《Doomsday Bunker Upgrade》


 Chapter 1

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    Christmas was around the corner. Having experienced multiple calamities year-round, people were eager for the year to come to an end, and with it, a respite.


    Ultimately, it was a painful year for all of mankind.


    Plague, Famine, War, and Death. The Biblical Four Horsemen of the Apocalypse had ravaged the world, and human beings had found themselves powerless against the wrath of mother nature.


    Even in the face of disaster, humanity had never given up hope. We were always fighting hard, putting the most precious golden spirit of mankind on display ¨C full of hope and unrelenting perseverance against adversity.


    However, it was as if God played a huge joke on mankind. On that day, a huge meteorite more than ten kilometers in diameter was discovered by astronomers. Current projections confirmed that the orbit of this huge meteorite would intersect with the Earth, and it would crash into it within a few months.


    The governments of various countries tried to keep the news under wraps as soon as they learned of it. To avoid widespread panic, almost every astronomer was issued a gag order.


    Nevertheless, that kind of news could not be contained for long.


    After all, the meteorite was looming in the sky. As it got closer to the Earth, amateur astronomers around the world could see the comet in the night sky growing brighter and bigger through their telescopes.


    Moreover, due to space operations and numerous countermeasures that were immediately deployed by governments of various countries, it was difficult not to take notice of it, especially in the era of the Internet.


    These clues naturally spread around the Internet, arousing eager discussion. Simultaneously, some foresighted people began to hoard materials after discovering the imminent crisis.


    There had been too many disasters this year, as many people had experienced.


    Food, medicine, protective equipment, communications equipment¡­ Those emergency supplies were sold out immediately.


    Fortunately, due to the huge number of disasters this year, companies that produced disaster-response essentials had drastically increased their output, There was an especially high demand for emergency food items that could be stored for 20 or even 40 years.


    Even though throughout that year, the demand for emergency food was second only to protective gear when compared with other essentials.


    Nevertheless, in Chen Xin¡¯s view, digging a bunker for oneself was more important than snapping up those supplies.


    Chen Xin was an internet writer. He made a living by writing for several websites. As a writer, his most valuable assets were his imagination and cognitive ability. After all, any successful form of writing had to have a clear organization of entertaining ideas and a coherent flow.


    That undoubtedly led Chen Xin¡¯s thinking to be more complicated than others when facing such a possible disaster.


    ¡®That meteorite would hit Earth sooner or later, how would humans avoid such tragedy?¡¯


    For the first time, that question arose in Chen Xin¡¯s mind.


    Fortunately, as an Internet writer, Chen Xin was never one to let his imagination run dry. He also had the habit of recording his ideas and then conceptualizing them. The outcome in which the meteorite struck the Earth was well within his predictions.


    Even while stocking up on supplies and searching the Internet for any information that could be found, Chen Xin had always remembered to revisit his collection of ideas and unfinished thoughts.


    When the giant meteorite strikes the Earth, it would first bring about a violent impact.


    Judging by the size of the meteorite, even if various countries had a space interception plan in place, the probability of success was low. The meteorite would likely break into many smaller fragments that could still cause widespread destruction.


    However, that did not mean that the damage would be reduced. A smaller meteorite did not imply that it was any less dangerous. After all, it was still a part of a rock that was ten kilometers across in diameter.


    Even if it were broken into smaller pieces, those meteorite fragments would still average several kilometers in size. If any of them stuck, it would be devastating.


    When a meteorite the size of more than five kilometers in diameter strikes the Earth, everything within a radius of at least one thousand kilometers would cease to exist.


    The impact would throw everything around the impact site directly into space. The thermal energy generated by the meteorite¡¯s friction with the atmosphere and the energy released by the impact would send out a wall of fire at least ten kilometers high, with temperatures exceeding thousands of degrees Celsius. The fiery wall would incinerate everything within a radius of at least 1,500 kilometers.


    Within the blast range, even if you could hide in an underground bunker, there was a high probability that the high temperature would roast you like the famous Meizhou stuffed barbecued chicken from Guangdong. Granted that you could dig deeper underground, you would be buried alive by the magnitude 11 earthquake that followed.


    If you were lucky, perhaps your fossilized remains would be dug up by humans tens of millions of years later.


    Should you be interested in leaving behind a message for mankind, you could raise your middle finger, and future humans would be moved by your optimistic, albeit satirical spirit.


    The shockwave caused by a meteorite impact would travel around the world at several times the speed of sound. No matter where you were on Earth, you could hear the violent sound of the impact.


    If you were on the opposite hemisphere where the meteorite hit, there would be no immediate danger. The shockwave would just be enough to remind you to hide in the bunker.


    However, that was only the beginning.


    Throughout the next few days, a firestorm made up of haze and rubble would cover the Earth¡¯s atmosphere. This would cause the global temperature from the two poles to the equator to rise to 70-200 degrees, turning Earth¡¯s surface into a gigantic oven.


    The entire surface would become unsuitable for human survival. All flora would be roasted by the spike in temperature. The harmful toxic gases produced by global fires would spread throughout the atmosphere and kill most of the surface organisms.


    Moreover, this was still just a prelude to the disaster. It would be like being served an appetizer before the main course.


    Due to the increase in atmospheric temperature, the sea level would also rise rapidly. The kinetic energy released by the meteorite impact would produce a tsunami that was thousands of meters high, and it would effectively decimate almost all coastal cities.


    The dust cloud set off by the impact and the haze formed by the toxic gases from the global fire would block out all sunlight, plunging the Earth into a long period of darkness for dozens or even hundreds of years.


    The material thrown into space by the meteorite impact and the smaller fragments entrapped within the meteorite itself would continue to rain down on Earth.


    It would be as if the hemisphere where the impact site was located was carpet-bombed. The continuous meteorite impact would greatly reduce the chances of survival.


    Even if one could hide in an underground bunker, it was impossible to survive the daily meteorite bombardment, especially when the fragments ranged from a size of a few meters to a few hundred meters.


    As for the opposite hemisphere of the impact site, it would fare better, but there would still be meteorites falling randomly. It could almost be said that there was a chance that the meteorites would smash several tall buildings when you went out.


    Even then, it would not be over yet, because the atmosphere would be covered by thick dust clouds and a haze formed by toxic gases. Within the next few months, the temperature would cool rapidly.


    If the high-latitude cities were not destroyed in the impact, their temperatures would drop to minus 70 degrees, while the equatorial regions would be slightly better off with temperatures around minus twenty or thirty degrees.


    As the darkness and extreme cold would last for up to a century, the new Ice Age would finally become a reality.

 Chapter 2

    The only difference between reality and a game was that you had neither energy towers to provide heat, nor robots to work. Moreover, you would not see sunlight for a hundred years.


    Faced with a calamity of this scale, Chen Xin felt that he did not need to do anything if the impact site was in the hemisphere where he was. He would eat well and have fun for a few months, then just raise his middle finger at the meteorite when it eventually falls.


    However, if luck was on his side, and the meteorite falls on the opposite hemisphere, then he should be able to survive the disaster by digging a deep enough bunker. He would then face a hundred years of extremely cold long nights.


    In that case, digging a bunker was not unrealistic.


    In fact, in the 1970s, when Vermillion and Russia had a bad relationship, Russia had planned to carry out a surgical nuclear strike against Vermillion. However, it was not followed through because the United States of America opposed the plan at that time.


    On the other hand, based on the news leaked in the USA newspapers, The Director proposed a plan to build underground bunkers. They invested a lot of manpower and material resources to construct a large number of air-raid shelters across the country. Those constructed at important and strategic locations were even connected by long underground tunnels.


    There were bunkers scattered in every city in Vermillion, and most of them were still intact.


    The air-raid shelters were usually 20 meters deep, 200 meters long, and 3 meters wide. The two walls were brick walls, and the roof of the cave was made out of cement boards that were held together by support tools.


    There was ventilation, electricity, lighting, and other equipment in the cave, which could be used to survive air raids during the war, as well as post-nuclear war temporary residences for emergency evacuation.


    Furthermore, those air-raid shelters were in use until the 1980s and 1990s.


    After the Soviet Union¡¯s collapse, due to the increase of Vermillion¡¯s overall national strength, the international situation had gradually improved. Those air-raid shelters gradually lost their place post-war, and many had been repurposed for civilian use. Many places became material warehouses, vacation spots during summer, and even underground commercial streets.


    Besides that, subway stations that were built in major cities and double-deck residential underground parking lots were also another form of an air-raid shelter. After all, subway stations that ran tens or even hundreds of meters deep made for excellent cover, as nuclear bombings or airstrikes were not enough to cause structural damage.


    At any rate, it would be difficult to destroy the overall structure of the bunkers, even with specially-designed earth-penetrating weapons or cloud blast bombs that had proven to be effective at underground destruction.


    For the first time, the subway lines that extended in all directions could serve as the main transportation network. The bomb bunkers and subway stations would evolve into underground cities like those seen in ¡°Wandering Earth¡±, but not as deep.


    Chen Xin looked through his ideas and the information he found on the Internet. He was fairly convinced that the government would start digging deep underground following the meteorite impact, to provide the people with the means of evacuation and self-rescue.


    However, simply digging a bunker could only guarantee people¡¯s survival when the disaster struck. How would mankind go on to survive the cold dark winter that would last for decades?


    Food storage? That was indeed a feasible method. Most emergency foods on the market had a shelf life of 5-10 years at room temperature, but as the global temperature drops, subzero temperatures would be sufficient to preserve those foods for decades or even up to a century.


    Nevertheless, in the few months before the meteorite hit, one would be considered very lucky to have collected enough food to last a few years. Unless you were prepared ahead of time, it was impossible to amass enough food to last a few decades.


    Moreover, there was another critical necessity ¨C energy.


    After the meteorite hits Earth, the impact would disrupt its ionosphere, sending out an EMP shockwave around the world that would render a large number of electronic devices useless. In that case, it was impractical to count on the electrical power supply being fully-functional.


    Although post-disaster reconstruction would start as soon as the environment had stabilized, and should the power supply be restored within a year, power generation required a source of energy.


    When the global temperature drops to subzero, the Three Gorges Project, Vermillion¡¯s largest water dam and hydroelectric power station would freeze into a huge lump of ice. All similar power stations in the country would also share the same fate, regardless of size.


    That would deprive Vermillion of nearly 20% of its power generation.


    It was not a small number. More than 70% of Vermillion¡¯s power came from thermal power stations. Under a global disaster of that scale, how many power stations and power supply lines would still be intact?


    The answer would be a very pessimistic number, because most of the high-voltage transmission lines in Vermillion were built at high altitudes, due to safety issues.


    Under ravaging firestorms and subzero temperatures, the probability of those cables surviving was really small.


    By that time, the situation would be akin to life during the ice age. Humans would need to harvest coal for heat and cooking food.


    To a large extent, society may also regress to the city-state era, where each city would work only for themselves and struggle to survive.


    Of course, with the Vermillion government¡¯s influence and execution capabilities, their basic government functions and social structure should remain. Life after the disaster may be a little tough, but mankind could still survive.


    On the other hand, having taken into consideration the various scenarios and actual conditions brought about by the meteorite impact, it would take at least one to three years for the situation to stabilize.


    Therefore, what laid before Chen Xin was how to prepare in those three months so that he could survive that catastrophe smoothly and get through the first few most turbulent years.


    Fortunately, when Chen Xin conceived of that idea, he had already formulated a complete plan following some serious discussions with friends on the Internet and in-depth research.


    If his plan was implemented from now, everything was still not too late despite the tight schedule!


    As he thought of that, Chen Xin did not waste any time. Through his connections, he hurriedly put together a team of trustworthy engineers. He planned to dig an underground bunker for himself.


    Regardless of whether the meteorite would hit Earth, and whether he would survive the first impact, it was always better to be prepared.


    In addition to digging bunkers, storage of food and drinking water was also very important. Chen Xin took out his mobile phone to check his bank balance and decided to go on a buying spree.


    Fortunately, due to prior disasters, Chen Xin had also stocked up a lot of things at home, such as gas masks and medical first aid kits. Those were items that he did not need to buy. What he needed to stock up instead were food and water.


    As long as there was food, drink, and a bunker to hide in, the necessities for human survival were not too elaborate.

 Chapter 3

    While Chen Xin was busy working to save himself, the governments of various countries were also not idling by.


    The first to take action was the five strongest nations on Earth.


    We had often ridiculed that the top five nations were in fact, only two and a half. Although the remaining two were close to being removed from the list, these five nations were still leading in terms of overall national strength and disaster-response when compared with the rest of the world.


    Ultimately, in the face of calamity, men had decided to put aside their differences and work together.


    Among the many operations carried out by various countries, the priority was to destroy the meteorite or change its orbit.


    After all, compared to surviving underground, that was simpler and less troublesome, and it could also minimize the damage of the impact.


    However, for a meteorite with a diameter of more than ten kilometers, it was an almost impossible feat considering Earth¡¯s existing technology.


    There were not many practical solutions that the countries could come up with.


    In the United Nations Special Assembly that was led by the top five nations, various plans were proposed and rejected. In the end, only three plans were approved by the majority.


    One of the plans was proposed by Vermillion. When the meteorite approaches the lunar orbit, a high-power thruster would be installed on its surface. With its propelling force combined with lunar gravitational force, the meteorite¡¯s orbit would be altered to prevent the meteorite from crashing into Earth.


    That plan was the most feasible and effective among the three, but the technical requirement was the highest.


    With the current aerospace technology possessed by mankind, only manned spaceflight in the Earth-Moon system had been successfully attempted. Humans had only launched unmanned probes in the outer reaches of the moon¡¯s orbit. To install a thruster on a meteorite that was approaching the moon¡¯s orbit was going to be a great test of human aerospace technology.


    Not to mention that the meteorite itself was a behemoth tens of kilometers in diameter.


    Even with the help of lunar gravity, the project still required the transportation of a thruster that was much more powerful than the largest spacecraft currently built by mankind, as well as the fuel needed to propel the meteorite.


    Even though humans could urgently modify a spacecraft in three months, the success rate of that plan was still low.


    The second plan was proposed by the USA. The plan was formulated upon references from Hollywood science-fiction films ¡°Armageddon¡± and ¡°Deep Impact¡±, thanks to the talent of Hollywood screenwriters.


    A selected team would land on the meteorite, dig a hole in it, plant a nuclear bomb, and then detonate it.


    If all went well, the force generated by the nuclear explosion would be sufficient to change the orbit of the meteorite. At worst, it would still break up the meteorite into smaller pieces, minimizing the damage caused by the impact.


    That solution was technically less difficult than the one proposed by Vermillion. Although both solutions required humans to land on the meteorite, it was much easier to install nuclear bombs than installing thrusters. Moreover, nuclear bombs that could push a meteorite forward were much easier to build than a high-powered thruster.


    There were ready-made nuclear bombs of that level in the top five nations¡¯ nuclear arsenals. Russia even stated on the spot that they could provide their Tsar Bombas if that plan was adopted.


    However, a big problem with that plan was that although a nuclear bomb explosion could sway a meteorite, it was more likely to destroy it, which would cause multiple smaller meteorites to hit the Earth.


    In that case, the damage to Earth¡¯s civilization would not be lower than that of the meteorite hitting the Earth as a whole, so the majority was more inclined to the plan proposed by Vermillion.


    Nevertheless, considering its difficulty, the Vermillion plan was retained as a necessary Plan B.


    As for the third proposal, it was proposed by Russia.


    Russia¡¯s plan was very simple and straightforward. It was crude and embodied the characteristics of a fighting nation. Their idea was to utilize all of the top five nations¡¯ nuclear weapons to carry out a concentrated nuclear attack on the meteorite. In short, to blow it to pieces.


    Although the fragments would still hit Earth¡¯s surface after entering the atmosphere, the damage they would bring was at least manageable, and most of them would burn up before they hit the ground. Granted, there would not be too many fragments reaching the Earth.


    The only problem with that plan was mankind¡¯s existing missile-launch technology. It was not powerful enough to deliver payloads too far into space, so we would have to wait until the meteorite was close enough to Earth to launch the nuclear bombs.


    In addition to that, to guarantee its hit rate, a spacecraft would be needed to travel with the nuclear bomb as guidance.


    However, there was a high probability the spacecraft would not survive after the hit. That was due to the overwhelming amount of shrapnel that it would face post-detonation.


    Much like laser guidance on the battlefield, if it was a cruise missile, the soldiers on the ground could still keep a safe distance from the target. However, if it was a thermobaric weapon or a nuclear bomb, it was difficult for all soldiers on the battlefield to survive.


    Even so, considering that it was a matter of life and death for human civilization, the various countries did not feel that making a smaller noble sacrifice that difficult a choice.


    Although the difficulty of implementation and the success rate of the three schemes were different, the astronauts who performed the mission were unlikely to survive either plan.


    After heated discussions, the countries finally decided to implement a combined-response plan, and the three plans were carried out simultaneously.


    Vermillion and the USA would first land on the surface of the meteorite, install thrusters and nuclear bombs respectively, and then try to use nuclear bombs and thrusters to change the orbit of the meteorite or explode it.


    Russia¡¯s plan would only be used as a backup. If the first two plans failed, then that would be humanity¡¯s last resort.


    The various countries would also equip their people with self-rescue measures, build underground bunkers, and gather resources to save as many people as possible.


    In the face of a common disaster, there was unprecedented unity between the world¡¯s powers at that time. Even the countries that did not have much say were actively contributing.


    The USA took the initiative to provide Vermillion with the Falcon Rocket. Every bit of effort could increase the chances of human survival even by a little. A technology blockade was not something that should be practiced at that moment.


    On the other hand, the Russians also opened up their nuclear arsenal. Several Tsar Bombas that were secretly preserved during the Soviet era were provided, two of which would be used in the USA¡¯s blasting operations.


    Concurrently, the top five nations pooled together and redirected all their global aerospace resources to serve in the implementation of the three plans.


    However, in addition to the deployment of disaster-response measures, the various countries were also preparing additional contingencies, should the grand plan fail.

 Chapter 4

    Vermillion cleared out all the air-raid shelters that were built that year and subsequently carried out overhauling and maintenance operations. They also upgraded the bunkers and expanded their capacity in the shortest time, to ensure that the refugees would have a greater chance of survival.


    Simultaneously, the underground transportation systems of major cities were rapidly being transformed. Abandoned platforms were being repurposed, subway stations rebuilt and expanded, and underground transportation networks connected¡­


    A series of work was underway in full swing. Despite the news of the meteorite hitting the Earth having spread like wildfire, the overall social situation in many countries was still stable due to strict regulations such as curfews.


    Fortunately, Chen Xin¡¯s bunker was successfully built. He was able to gather enough food to last himself at least two years because he prepared ahead of time.


    However, he did not store much drinking water. Even with large water tanks and sewage treatment systems being installed in the bunker, he still felt huge pressure when considering that humans would face a hundred years¡¯ worth of extreme cold darkness.


    At that point, the best he could do was to collect as many shelf-stable bottled drinking water as he could.


    It was just that everyone was in a hurry to stock up at that time. Bottled drinking water and emergency food supplies had become the most in-demand items. All distribution channels were experiencing a shortage of supply which made it very difficult for Chen Xin to procure more goods.


    Fortunately, Chen Xin joined a small group formed by outdoor sports enthusiasts. After the news of the disaster spread, his friends in the group pooled together their resources to save themselves. Many people were busy with preparations for their own bunkers, just like Chen Xin.


    Those friends in the group suggested that they could use empty barrels to store tap water, which allowed Chen Xin to stockpile a lot of freshwater resources.


    Although barreled tap water was not as shelf-stable as bottled purified water and was unsuitable for drinking, Cen Xin did not have much of a choice. Under extreme conditions, you would have to drink urine or even water from feces. What was so bad about unclean tap water?


    The city that Chen Xin lived in was located along the Dongting Lake in the middle reaches of the Yangtze River. The population density was not high. Due to personal reasons, he did not live in the city but lived alone in the suburbs instead. His residence was near some woods and it was quite convenient to dig a hole for an underground bunker.


    With the help of construction machinery, it was not difficult to dig an underground bunker that was capable of defending against natural disasters. Also, the project undertaken by Chen Xin was run by a relatively professional engineering team who was working with small excavators. Under those circumstances, the bunker was quickly completed, and Chen Xin also moved all his supplies into it.


    That engineering team went way back with Chen Xin, and he was also close to the foreman. The quality of the construction left Chen Xin very satisfied.


    Because of the high temperature and extreme cold caused by the meteorite impact, Chen Xin wanted to dig a very deep bunker. He had found it best to go as deep as fifty or sixty meters, like a subway station.


    However, that was a bit unrealistic. The engineering team could do it, but it would take too much time and work. So Chen Xin decided to dig a downward passage oblique to the ground under the mountain near his home, and then build a bunker at its base.


    That was also a common practice for building air-raid shelters in various countries. Using the mountain itself as a bunker could effectively cut the work by half and at the same time provide adequate protection.


    Chen Xin¡¯s bunker was not too big, totaling about 300 square meters. Besides, he still needed to fit a garage, a water tank, a fuel tank, farming equipment, and a greenhouse for growing food. What was left would be the livable area, which was only 30 or 40 square meters.


    Nevertheless, for Chen Xin alone, that area was more than sufficient.


    As for the living conditions, Chen Xin¡¯s bunker was not merely a cave. After the hole was excavated, a set of specially-customized container homes were installed.


    Besides good thermal insulation, a variety of living facilities were also readily available. Chen Xin would be able to live comfortably even in extreme temperatures.


    That kind of container housing was technologically mature. During the epidemic at the beginning of the year, the emergency hospitals that were built by many countries also used similar container homes.


    Compared to traditional reinforced concrete, that kind of container homes could be prefabricated in the factory and be readily assembled when shipped to the site. It was far more time-saving, and it was cheap.


    Even so, the entire set of container homes, plus the construction cost of the bunker still bled Chen Xin¡¯s savings dry.


    On the other hand, after living in his finally-completed bunker, Chen Xin felt that it was well worth the money.


    He took a few photos of his bunker and sent them to a small survival group which consisted of himself and his friends. Chen Xin immediately attracted envy. He was very well-prepared, and the bunker would greatly increase Chen Xin¡¯s chances of survival when doomsday came.


    There were even girls in the group who sent private messages to Chen Xin asking if he lacked a girlfriend. As long as Chen Xin agreed for her to move in, she could even bring another girlfriend if he felt that one was not enough.


    Looking at the photos of the two beautiful girls whom Chen Xin barely knew, he almost nodded in agreement.


    However, Chen Xin managed to hold back. Although his situation was ideal, he was a little tight on supplies. It was possible to accommodate two more girls, but it would greatly reduce his chances of survival.


    After all, according to his estimation, after the disaster struck, many flora and fauna would die, and the source of food would likely be reduced to only mice, cockroaches, and mushrooms. Those would not disappear even if humans were extinct. That was his only guarantee of survival.


    As for building a greenhouse, it could indeed provide some food, but its upkeep would require a lot of resources. For Chen Xin, he was not sure how long his resources could sustain the greenhouse.


    Therefore, reducing consumption as much as possible and lasting through the post-disaster reconstruction after the environment stabilizes were the key to his survival in that predicament.


    Nonetheless, despite all possible preparations, Chen Xin still hoped that he would not need to use them when the time came. He sincerely wished that all countries could resolve this crisis.


    After all, who would want to hide in a hole and eat mushrooms, when they could live freely in the sun?

 Chapter 5

    Chen Xin¡¯s construction of his bunker was actually illegal. In terms of procedures, he neither filed for a building permit nor obtained civil approval from his local government.


    However, in the face of the imminent disaster, the whole country had entered a state of emergency. All manpower and material resources of the municipal departments had been diverted to the ongoing civil air defense projects. The state also encouraged its people to dig up bunkers, so no one paid any attention to Chen Xin¡¯s underground project.


    The civil air defense project was a nationwide project that Vermillion had been working on since the 1970s. Although it was hidden from the public eye, there were actually many civil air defense projects underway in major cities. People just did not pay much attention.


    For example, it would seem there was nothing out of the ordinary regarding the underground parking lots of shopping malls or residential areas except for the heavy lead-grey iron doors at its exits. However, that would indeed make it part of a civil air defense project. It could be used as an air-raid shelter or temporary refuge in event of a foreign invasion or nuclear war.


    And now, despite possible meteorite impacts, the country was not only strengthening its defenses but also vigorously transforming those civil air defense projects into bunkers that could accommodate residents for a long time.


    Due to the high temperature generated by the impact, dust clouds, and toxic haze that would engulf the atmosphere. Earth¡¯s surface would become unsuitable for human survival for the next 100 years as temperatures dropped. The only thing left for humans on the surface would be extended periods of darkness and subzero temperatures, which may last the next few decades or even hundreds of years.


    Therefore, under such circumstances, the underground civil air defense project turned bunkers would become the last standing home for human beings to survive and live in.


    Originally, those civil air defense projects did not consider long-term residential use when constructed as they were designed only for short-term refuge during an attack.


    Now that humans were more likely to have to live underground, it became necessary to overhaul those existing civil air defense projects.


    Especially after a meteorite impact, it would bring about an intense but short heatwave and extremely cold weather, which heightened the requirements for the ventilation facilities of those civil air defense projects.


    Therefore, while the state had joined forces with other countries in the world to actively respond to the imminent impact, municipalities and engineering personnel across the country had also been mobilized to upgrade and transform those civil air defense projects, as well as expand their holding capacities.


    Large underground facilities such as subway stations and underground shopping malls were being planned to become future underground cities.


    After all, a facility like a subway station that was buried deep underground and could be connected to other subway stations at the same time was the ideal choice for the base of an underground city.


    That was actually one of the subway stations¡¯ predicted functions during its planning and construction.


    It was known that when the Germans air-raided London during World War II, Londoners escaped the German bombing by hiding in subway stations.


    In addition to the transformation of civil air defense projects, the stockpiling of various resources had also become the focus of the country¡¯s response to disasters.


    Food would not be in short supply for the country in the foreseeable future. The country¡¯s food reserves were sufficient to last for three years, but most of the food was stored in designated granaries across the country. Now, it needed to be distributed from those granaries to bunkers across various cities.


    All tasks were being carried out in a disciplined and orderly manner. Some people tried to take advantage of the chaos by instigating riots and looting supplies but were soon subdued by the army. After the state had announced a state of emergency, it was the army who were responsible for maintaining law and order instead of the police. Those who sought the death-penalty naturally had their wishes fulfilled.


    Under the country¡¯s meticulous planning and stringent control, most of the bunkers had been completed on schedule, and material reserves had been put in place. The bunkers were at that time ready for civilians to move in.


    Simultaneously, the population along coastal areas were evacuated inland, considering that the meteorite could hit the Pacific Ocean. Although this had caused serious losses to the national economy, in the face of a possible tsunami, the country could not bear to put the lives of hundreds of millions of people on the southeast coast at risk in return for economic benefit.


    Just like the famous saying of our ancestors, ¡°We live to fight another day¡±. As long as people were alive, the civilization could be rebuilt; but if people were gone, who would take on that responsibility?


    In just a few months, the country had to fabricate a plan to deal with meteorites as well as putting disaster-response measures in place across the country. Even in a country like Vermillion, where the government had a great influence, it must do its best. The country could only barely manage to complete the work on schedule if everyone worked in unison towards one goal.


    On the other hand, in countries where the government was not in control, society had fallen into a state of collapse.


    The order of small countries in Southeast Asia, the Middle East, Africa, and Latin America had entirely collapsed because their governments were unable to respond to a crisis of such magnitude. At that time, those communities had entered a state of disorder.


    People in those areas would kill for a pack of food. Human life was not even as valuable as a piece of bread.


    In those areas, humans had regressed to their most primitive state. It was to kill or be killed. The only thing they could think about was how to survive.


    Even though the people in other areas where order was still intact thought the same way, the steps they took to ensure their survival were very different.


    If it was before, other countries might still lend a hand to other regions in need, but now all countries were overwhelmed. Even the top five nations of Earth could only look after themselves in the face of the impending global catastrophe.


    Even among the top five nations, only Vermillion was in the best condition. Its government had a high degree of control over the country. Although Britain and Gaul were not in a state of disorder, the society was still in utter chaos. There were large numbers of demonstrations and riots. Those events had put the governments of the two countries in a dire situation.


    As for Russia, the situation was much better compared to Britain and Gaul. Especially as a former superpower, Russia retained most of the Red Army¡¯s legacy. With the blessings of its Soviet heritage, coupled with its unique geographical environment and climatic conditions, Russia did not experience much chaos, and its predicament was much better than that of Britain and Gaul.


    On the other hand, the situation of the USA, the only superpower surviving on Earth, seemed a bit strange.

 Chapter 6

    Some states in the USA were in good condition because of the unique political system in which each state was autonomous. Citizens stocked up supplies and dug bunkers in an orderly manner. They actively participated in the prevention of the disaster. However, some states had fallen into bigger chaos than Britain and Gaul, where the local state government had lost control of the situation.


    As for the federal government of the USA, their resources were focused on the defense against the meteorite. In addition, the government itself had limited control over the states. Therefore, they simply kept a blind eye and let the state governments handle their own affairs so that they could fully focus on the defense plan.


    After all, as long as they could manage to change the orbit of the meteorite, Earth would be freed from impending disaster. The many disturbances and social problems caused by the impacts of the meteorite would also subside at that time. Then, the government would only need to supervise the post-disaster recovery phase in all states.


    Perhaps, it was because the United Nations had those thoughts, that the disaster prevention preparations were not ideal.


    Of course, the USA also had shelters and nuclear bunkers, but most of these were built during the Cold War.


    The Cold War ended along with the dissolution of the Soviet Union. The USA became the world¡¯s superpower and commanded the strongest military. The country was safe, and the shelters and nuclear bunkers were abandoned as they did not serve any further purpose.


    Although there was a saying that went by ¡°Peaceful America, shootouts every day¡±, the two World Wars were never fought on American soil. In dealing with possible disasters, the Americans had always maintained a kind of optimism that often confused other countries. It was as if they did not have any sense of danger.


    To face the disaster, normal American citizens could only rely on their own basements, but that only included families that could afford to live in villas. As for the poor, they could only live in their apartments. How was it possible for them to find any basements as a bunker?


    Of course, the truly wealthy ones would build their own bunkers with complete facilities and living supplies. That was indeed unmatched by other countries.


    However, although all countries had their own problems to handle, they never slacked in the defense against the meteorite. They mobilized all possible resources and forces they could to ensure all three plans would be carried out smoothly.


    At that time, none of the countries could hide their nuclear silos any longer. Both hidden and known nuclear silos had already entered a ready combat state. The nuclear warheads had been loaded with missiles and were ready for launch.


    As the core of the three plans, the space shuttles of Vermillion, USA, and Russia were completed around-the-clock. They would only have to wait for the arrival of the meteorite and the plans could be put in motion.


    The USA deployed two space shuttles, the Atlantis and the Endeavour which were out of service. They overhauled and repaired the shuttles regardless of the cost. These two old shuttles that had been out of service for more than 20 years were brought onto the launch pad once again.


    According to the USA¡¯s plan, not only did they need to carry nuclear bombs to propel or detonate asteroids, but they also needed to carry drilling rigs as well as crews to operate them, and to plant the nuclear bombs. They would also have to perform a successful landing while carrying a heavy load.


    The USA¡¯s spacecraft were the only ones in the world that, besides having such carrying capacities, could also re-launch after landing on the meteorite.


    On the other hand, after the United States provided the Falcon Rocket, Vermillion combined it with its own Long March rockets to form a heavy-lift spacecraft with multiple engines. Its job was to apply sufficient thrust to the meteorite as it approached the moon to alter the meteorite¡¯s orbit, with the help of lunar gravity.


    However, all the data they had at that point was based on speculation. Nobody knew how heavy the meteorite was, and whether Vermillion¡¯s giant rocket could achieve sufficient thrust to change its orbit.


    After much deliberation, the United Nations operation team decided to adjust the plan. First, the United States¡¯ crew would land on the meteorite and carry out their plan. They would drill holes to plant the nuclear bombs and blow up the meteorite into two pieces, one big and one small to reduce the weight of the main body.


    At that same time, Vermillion would install the heavy-lift spacecraft onto the surface of the bigger fragment. They would change the orbit of that meteorite and deviate it from its impact trajectory with the combined forces of lunar gravity, the thrust from the spacecraft itself, and the thrust from the nuclear explosions.


    As for the remaining fragments, it would be up to the Russians. They would direct a large number of nuclear warheads launched from Earth to conduct a concentrated nuclear attack on the smaller meteorite fragments until they were completely shattered.


    If the whole plan went well, the large meteorite that was likely to cause human extinction would eventually be blown into a pile of debris in Earth¡¯s low orbit, and then fall into the Earth¡¯s atmosphere and incinerate.


    Maybe some larger fragments would eventually fall on Earth, causing some damage, but that level of disaster was still bearable for overall human civilization.


    When Vermillion, the United States, and Russia were ready to respond, the meteorite had finally closed by the moon¡¯s orbit and was gradually approaching Earth.


    The three teams that had been on standby for a long time were launched into space one after another. They would refuel at the International Space Station and Tiangong Space Station in low-Earth orbit and then use the gravity of Earth and the moon to accelerate. That was so that Vermillion and USA¡¯s spacecraft could accelerate to a speed that would allow it to land on the surface of the meteorite.


    To achieve that, Vermillion had sped up the completion of the Tiangong Space Station in the past three months while the United States carried out a major overhaul of the International Space Station. The two countries sent a total of six astronauts as the operation team to ensure that the stations could provide refueling services for their spacecraft.


    The fuel needed for the entire project had also been launched to the space stations with the assistance of the SLS system. They were only waiting for both spacecraft to arrive at the respective space stations.


    The rescue effort that affected the fate of all mankind had attracted the attention of everyone on Earth. All major media outlets and TV stations broadcasted the operation live for 24 hours a day.


    Whether a person was a religious believer or an atheist, everyone prayed for the success of that plan.


    Under the attention of six billion people around the world, Vermillion¡¯s spacecraft and the United States¡¯ spacecraft arrived at the Tiangong Space Station and the International Space Station respectively and started refueling.


    As for the Russians, because they were responsible for intercepting the meteorites, they would not mobilize until Vermillion and the United States began their operation. After all, their mission was to direct those nuclear warheads. Relatively speaking, it was not necessary to launch their space shuttle so early.

 Chapter 7

    Chen Xin also sat in front of the TV and watched the broadcast. After all, it was a life and death situation involving all of mankind and every major news outlet on Earth was reporting the incident around the clock.


    Although the meteorite was getting closer to Earth and all countries had issued warnings, the meteorite was only approaching the moon¡¯s orbit. The Earth had not yet been substantially affected. That was why Chen Xin did not hide in the bunker that he dug.


    The bunker might be safe, but there was no internet and TV. Chen Xin wanted to understand the situation of the rescue operation, so he chose to watch TV at home.


    As for other people in the city where Chen Xin was located, they were evacuated one after another during that period. In batches, they entered bunkers that were mostly remodeled.


    If the operation went well, they would leave the bunkers after the meteorite was intercepted successfully. However, if the interception failed, everyone would spend the rest of their lives in the bunkers.


    Chen Xin did not live in the city due to personal reasons. Although government workers had urged him to go to the bunker, Chen Xin stayed at home rather than going to the bunker built by the country because he had dug his own bunker.


    Moreover, although the country had tried its best to remodel the bunkers and was also trying its best to accommodate everyone, not everyone could enter the refuge. This was due to some of the bunkers not being completed in time and having limited capacity.


    According to Chen Xin¡¯s prediction, the city where he lived could still manage to handle it because the population was not huge. Most people could still enter the bunker.


    However, in terms of the whole country, Chen Xin thought that it would already be remarkable to be able to relocate 80% of the population into bunkers.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Vermillion and the United States¡¯ spacecraft would set off once again from the Tiangong Space Station and the International Space Station after they had completed refueling.


    They would first orbit the Earth and accelerate toward the moon with the help of the Earth¡¯s gravity. Then, they would accelerate a second time with help of the moon¡¯s gravity so that the spacecraft could synchronize with the meteorite¡¯s travel speed. Only then they could accurately land on the meteorite.


    Looking at the three spacecraft that gradually became smaller from the camera at the space station, Chen Xin prayed in silence for the warriors on board.


    The hope of all mankind rested on them. If the operation failed, mankind would have to face global extinction as the dinosaurs did sixty-five million years ago when the meteorite struck the Gulf of Mexico.


    Some people may argue that the cause of the dinosaurs¡¯ extinction could not be identified yet as a meteorite impact. However, Chen Xin could say with full confidence that if the meteorite approaching Earth crashed, ninety percent of living species would become extinct. Whether it was land or sea creatures, they would face the same catastrophe.


    Birds, as the last descendants of dinosaurs, might have escaped the previous disaster, but they might not be so lucky this time. The extreme temperatures and toxic gases brought by the firestorm that would sweep the world, accompanied by extremely cold nights would wipe out birds in the skies, large creatures on land, most plants, and all the fishes in the shallow parts of the ocean.


    Only tenacious animals such as mice and cockroaches that were good at digging holes could escape this catastrophe, but it was also unknown whether they could survive the extremely cold nights when food was scarce.


    As for marine life, there was nothing to worry about. Although marine life ecology in the shallow sea area would be devastated, the marine life living in the deep sea would not go extinct. Even some shallow sea marine life could survive if they were lucky enough.


    Humans, on the other hand, would have to depend on their luck.


    People who lived in countries where the social order had not collapsed would at least have the government organize an asylum for them. After surviving the disasters following the meteorite impact, there was still a high probability for them to survive and preserve human civilization.


    However, people living in countries where the social order had collapsed were not as lucky. If they lived far away from the point of impact, managed to find a solid basement, and stocked up on sufficient food supplies, there was still a chance to survive.


    Otherwise, they would very likely die within a few days from the ensuing disasters caused by the meteorite impact.


    Of course, if they were a little unlucky and lived near the point of impact, then they might not be able to even survive for a day. They would die an immediate and painless death.


    Although the TV station had been broadcasting live, Chen Xin did not stare at the TV all day long because it would take quite some time for the spacecraft to arrive at the moon¡¯s orbit. Instead, he was doing his final preparations before entering the bunker.


    Although Chen Xin hoped that the operation that dictated the fate of six billion people would succeed, he was not optimistic about it.


    Vermillion and the United States intended to blow up the meteorite with nuclear bombs, then propel the meteorite away from its impact trajectory with thrusters. That scheme sounded good, and its feasibility was not low. By disregarding the cost, it was indeed possible with mankind¡¯s current technology, but there were also many uncertainties.


    For example, before landing on the meteorite, there would be flows of debris around the meteorite which would prevent the spacecraft from landing, or even worse, destroy the spacecraft. Furthermore, there would be a possibility that the meteorite surface was too tough to drill holes into.


    A meteorite was not a sphere with a uniform texture. Its irregular shape and uneven texture might withstand the blasts of the nuclear bombs without even breaking apart. Or, it may be blown too wide apart and split into several pieces.


    If it was not blown apart, the texture of the meteorite may be harder than expected, which meant its mass would also be much larger. In that case, the heavy spacecraft prepared by Vermillion may not be able to propel the meteorite, or the thrust might be insufficient to completely change its orbit.


    In that case, mankind could only rely on the Russians to strike down the meteorite with all available nuclear warheads on earth.


    Even so, the world would suffer a huge wave of meteorite showers, causing astronomical losses to human civilization.


    If the meteorite exploded into several pieces, that would be the worst-case scenario.


    That was because Vermillion had only prepared one heavy-lift spacecraft and could only propel one meteorite at a time.

 Chapter 8

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    If the situation evolved to the meteorite getting blown into several pieces, the largest piece would very likely be propelled away by Vermillion¡¯s spacecraft, but the remaining pieces would still strike Earth.


    The nuclear warheads prepared by the Russians might destroy some or all of them. If they struck all of them, there would be a massive wave of meteorite showers.


    If there was a relatively large piece of meteorite that was missed¡­


    Mankind would redraw the world map and outlines of all the continents again.


    That was why Chen Xin was not optimistic about the operation. There were too many uncertainties that could affect its success rate.


    Nevertheless, mankind did not have the time and leeway to think about those. There were only two choices before mankind, to fight for the small probability of surviving or to give up and perish along with ninety percent of living creatures, facing the same fate as the dinosaurs.


    Therefore, mankind could only try their best to adopt a plan that had the most feasibility and a certain success rate, in hopes of saving the Earth and humanity.


    Let¡¯s pray that they could succeed. If there was a God, no matter which God it was, please bless those brave astronauts to complete their mission, to save the Earth and mankind!


    Chen Xin prayed piously, chanting the names of all the Gods, even those of ancient rulers and foreign deities. At that time, it would be much better to have any unknown disaster that could drive mankind crazy rather than have a meteorite impact, where everyone could only helplessly stand and point their middle finger at it.


    After all, prayers were only for psychological comfort. After praying for a while, Chen Xin organized some things that were to be moved to the bunker, packed them in boxes, and transported them.


    Chen Xin had already moved all the supplies such as food and drinking water after the bunker was dug up. He even drove his car into the reserved garage.


    The things he had just moved down were some furniture, personal belongings, and clothes.


    As for electronic products, the TV was still at home while his computers and gaming consoles were. Chen Xin would have to wait and decide whether he would move the TV into the bunker depending on the outcome of the operation.


    Although it could be foreseen that electricity and the internet would be cut off should the operation fail, Chen Xin would be alone in the bunker. According to his prediction, he would need to hide underground for at least one year. He would probably die of boredom if he had nothing to occupy his time with.


    As for the EMP impact caused by the meteorite impact disrupting Earth¡¯s ionosphere, it would be easier for Chen Xin to defend against it. That was because his container homes were made of metal and could be regarded as Faraday cages. Plus, it was buried deep underground, which would limit the EMP impact¡¯s damage to his electronic products.


    After arranging his things, Chen Xin also checked the three tons of gasoline he had stored in a large custom-made water tank. That was the result of the combined efforts of him and his father¡¯s old contacts. The gasoline would be his sole fuel reserve for the next one to two years.


    Of course, the gasoline was not used for heating or cooking, nor was it used for the car parked in the garage. Although he would eventually use the gasoline to cook when necessary or to start up his car, it was not intended to be used for the moment.


    In fact, the gasoline was intended as a backup in case of a power outage so that he could generate electricity.


    When he built that underground bunker, Chen Xin took into account the power outage and bought two small household generators.


    Those kinds of household generators were small, and an adult can even carry it one-handed. Its power generation range was around 3-10KW, which was sufficient for household use.


    The two small household generators purchased by Chen Xin only had a power of 5.5KW, which was considered to be a medium model. After being filled, The fuel tank could hold about 20 liters of fuel and could work for 12-15 hours at rated power.


    Considering the three tons of gasoline that Chen Xin had in reserve, it was enough to last him for a whole year.


    Of course, when he used it, he would not use up a full tank in a day, that would be too extravagant.


    Chen Xin had prepared a large battery for the bunker. The plan was to use the generator for six to eight hours a day. In addition to fulfilling normal power consumption, excess power would be stored to minimize fuel consumption.


    After all, there were no high-powered electrical appliances in the bunker. It was at most an induction cooker, an electric blanket, and any electronics that Chen Xin may use. The small household generators that he prepared were more than enough for that. He would only have to work for one-third of a day to ensure a sufficient power supply for the rest of the day.


    Although the long nights and cold winter would last for decades, there were only so many supplies that Chen Xin could collect.


    As for whether those materials could last him for a year, and what should be done after they were depleted, Chen Xin remained optimistic.


    Considering the current preparations made by the country, as long as the meteorite did not directly crash onto Vermillion, then the basic social structure of the country and most of the population would be preserved. Although everyone would be living in the bunkers by then, they would eventually survive.


    In one year, when the environment had stabilized, the country would also commence reconstruction work and restore social order.


    At that time, Chen Xin believed that he would be able to find a way to obtain food or fuel. Worse comes to worst, he could still rely on government bunkers. He was not worried about survival at that moment.


    After he checked his inventory and confirmed that all the supplies were sufficient for a year with a few months¡¯ worth of surplus, Chen Xin left the bunker. He returned home and once again paid attention to the latest progress of the operation.


    Even though he was not optimistic about the operation¡¯s success rate, if they managed to save Earth, Chen Xin would still be very happy because he would not need to spend the rest of his life in a bunker.


    However, the spacecraft would obviously take some time. It would take about four to five days for them to reach the moon¡¯s orbit, given the speed that humans launched the spacecraft at. After all, they would need to accelerate with help from the Earth¡¯s gravity to save time and fuel.


    At that moment, they had only just completed the first lap of acceleration. They would still need to orbit Earth twice to gain sufficient kinetic energy and speed to fly toward the moon. Only then they could carry out the operation after landing on the meteorite.

 Chapter 9

    In the quiet and eerie environs of space, the moon was quietly orbiting Earth.


    Not far from the moon¡¯s orbit, a meteorite with a long, bright, and sparse comet tail was on course toward Earth. If no other factors were affecting it, the meteorite would hit Earth in a few days, causing the same mass extinction that Earth faced sixty-five million years ago.


    It was just that humans dominated the Earth today instead of dinosaurs sixty-five million years ago. The wisdom and technology they possessed allowed them not only to confront but also achieve the possibility of surviving the meteorite impact.


    At that time in the moon¡¯s orbit, the three aircraft that were flying toward the meteorite were carrying the strongest weapons mankind ever created, along with hopes of destroying the meteorite to prevent catastrophe.


    ¡°Houston, that is Endeavour. We are close to the meteorite. Request for approval to commence the rescue plan.¡± On the Endeavour, the captain was communicating with Earth.


    There were nervous expressions on all of the seven astronauts in the cabin, but there was also a little bit of excitement, along with a sense of duty.


    That was because they carried the hopes of all mankind. If the operation was successful, they would also become heroes who saved the world.


    Perhaps Hollywood had made too many movies about saving the Earth. Those astronauts felt more or less like they were the protagonists of an American science-fiction film and that they would definitely be able to save the world.


    That boosted the confidence of the astronauts. Together with the other seven astronauts on Atlantis, those astronauts from the United States maintained an optimistic attitude that they would be able to complete the mission.


    Optimism was not a bad thing. After all, if they had failed, what awaited Earth was a devastating catastrophe. They carried the burden of the lives of trillions of living creatures.


    In fact, the astronauts of the United States, Vermillion, and Russia had personal psychologists assigned to counsel them after learning about their mission, which kept them in an optimistic mental-state.


    That was because the burden on their shoulders was far too heavy. The lives of all of mankind and living creatures were dependent on them. If their resilience were slightly weaker, they were very likely to experience an emotional breakdown.


    Although astronauts themselves were people with extraordinary mental health who were carefully selected after many levels of screening, not to mention only the most experienced with the best psych evaluation were selected for that mission, nobody dared to place their bets on them. That kind of mission that could directly affect mankind¡¯s fate was too much stress to bear.


    In the instance where an astronaut failed to handle the emotional pressure and collapsed, it would ruin mankind¡¯s only opportunity to save themselves.


    Therefore, the United Nations operation team deliberately kept those astronauts in a more optimistic attitude. Not only did it make them more emotionally stable, but also allowed them to be in a better mindset when performing the tasks, which could increase the success rate of the mission.


    At a time where the fate of six billion humans was dependent on the mission, the operation team would try out any method that could increase its success rate, as long as it was effective.


    It was just that although the UN¡¯s action team had mobilized all the resources in the world and did everything possible to support the rescue plan while hoping to increase the mission¡¯s success rate, everyone knew that it was still a gamble. A gamble for a slim chance to succeed at the cost of mankind¡¯s fate.


    Despite it being a gamble, mankind still had hopes of winning. This would ring true if the astronauts of the three countries succeeded in their mission and eliminated the threat of the meteorite impacting Earth.


    As a result, under the attention of six billion people around the world, the two spacecraft Endeavour and Atlantis, which had gotten approval from NASA flew toward the meteorite while the spacecraft piloted by Vermillion astronauts remained. They needed to wait for the United States to complete their task before they could begin their task.


    At the same time on Earth, Chen Xin was using his mobile phone to discuss the rescue mission with his group of friends in the survival group chat while nervously watching the live broadcast of both United States¡¯ spacecraft approaching toward the meteorite which was captured by Vermillion¡¯s spacecraft¡¯s cameras.


    Landing on the surface of a meteorite was not as simple. Even if the United States used a spacecraft that could take off and land like an ordinary airplane, it was still a very difficult feat.


    First of all, the spacecraft was not launched directly toward the meteorite. Otherwise, the spacecraft would have difficulty landing due to the difference in speed between the two, and would even crash directly onto the meteorite.


    Therefore, the two spacecraft had to be directed in the same direction as the meteorite, and with sufficient speed, maintain a relatively consistent velocity with the meteorite so that they could land on the surface.


    The intersection point at the orbit was calculated in advance so that Endeavour and Atlantis could approach the meteorite at a synchronized speed after being accelerated by the moon¡¯s gravity. Then, they could land on a relatively flat surface of the meteorite.


    However, the meteorite had formed a comet tail as it was gradually approaching the sun.


    That was the trajectory formed in space by the material on the surface of the meteorite under the influence of the solar wind. If looked at from earth, it would be a very beautiful flash of light.


    If they wanted to go through it, it would be equivalent to driving in a sandstorm or hailstorm for the astronauts. Life or death would depend on luck.


    If they were lucky, it may just be a slightly windier sandstorm. It would be difficult to land but it would not be fatal.


    If they were unlucky, there might be hailstones that could smash a car¡¯s window and dent the roof of a car. It was enough to destroy the spacecraft.


    At that moment, the astronauts on Endeavour and Atlantis were gambling with their lives, betting on a chance to land on the meteorite.


    ¡°Houston! We are in trouble. The meteorites are surrounded by pyroclastic flows. They are blocking our way. We need help!¡± The voice of the American astronaut on TV made Chen Xin¡¯s worries come true.


    As it was a simultaneous live broadcast to six billion people around the world, there was no such thing as inserting an advertisement or cutting the view back to the studio. The astronaut¡¯s call for help caused an instant commotion around the world.


    In the small group established by Chen Xin and his friends, many people had already begun to cry that the rescue operation would fail. They felt that they would live in a bunker for the rest of their lives.

 Chapter 10

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    ¡°It¡¯s over! If the United States¡¯ astronauts can¡¯t land, our astronauts can¡¯t land either. In that case, the meteorite could neither be blown up nor pushed away. It will be over for Earth!¡±


    ¡°I am panicking a lot now. could someone tell me if a bunker 50 meters underground could withstand the impact of meteorites or not?!¡±


    ¡°We¡¯re so dead! The bunkers near my house are already full. My sister, my besties, and I haven¡¯t gotten a place in the bunkers. We have to wait for the next slot!¡±


    ¡°Aren¡¯t there bigshots in the group who built their own bunkers? Could we stay at your refuge? I¡¯ll send my sister¡¯s and my bestie¡¯s pictures over! (picture) This is my sister and my bestie, what do you guys think about it?!¡±


    Looking at the seemingly crooked discussions in the group, Chen Xin did not hold his hands back and opened the picture. He did not intend to let them come over but just wanted to take a look at the clothes the ladies were wearing.


    Right, just to take a look at their clothes, he did not have other intentions.


    After all, if the meteorite really crashed, it was estimated that there would be no girls in low-cuts and backless outfits in the next one to two hundred years. The weather conditions would not allow them to.


    Aside from the drama, Chen Xin continued to pay attention to the rescue operation. He felt that neither the UN operation team nor the astronauts of Vermillion and the USA would give up their mission because of the pyroclastic flow on the surface of the meteorite.


    At that time, there were two counter-solutions. One was to rely on Team Vermillion to disrupt the gravity near the meteorite with the weight of their heavy-lift spacecraft, thereby attracting part of the pyroclastic flow, opening a gap for Team USA, and allowing them to land on the surface of the meteorite.


    If they did this, then Team Vermillion would not be able to complete their original mission.


    After all, the fuel carried on the spacecraft was limited. If they did this, they would consume the fuel originally planned for completing their tasks, which may cause the mission to fail.


    Of course, they could also adopt another scheme. They could drop a nuclear bomb first and blow away the pyroclastic flow on the surface of the meteorite. After all, both spacecraft were equipped with Tsar Bombas sponsored by the Russians.


    With blast energy large enough to move Europe, the Tsar Bombas could blow away the pyroclastic flow on the surface of the meteorite temporarily.


    After landing on the meteorite, as long as the United States¡¯ astronauts could successfully plant the nuclear bombs, the explosion would not only blow up the meteorite but also blow away the newly generated pyroclastic flow. Then, Team Vermillion could also land and alter the meteorite¡¯s trajectory with the thrusters from their heavy weighted spacecraft, deviating the meteorite from its impact trajectory.


    For Team USA, they had little choice.


    Although using up a nuclear bomb would leave them with only one left to blow up the meteorite, there was still hope in completing the mission. Otherwise, they could only choose to return and give up on changing the orbit of the meteorite.


    Therefore after a little consideration and inquiring about the specific conditions of the astronauts on both spacecraft, the United States decided to use a nuclear bomb to blow away the pyroclastic flow so that both spacecraft could land successfully.


    Soon on the live broadcast, one of the United States¡¯ spacecraft, the Atlantis, opened its cabin and dropped a nuclear bomb.


    The Tsar Bomba dropped by Atlantis was quickly captured by the gravitational force of the meteorite and fell toward the surface of it. The astronauts in the spacecraft also took the opportunity to detonate the nuclear bomb.


    This was the second time in human history that nuclear weapons were used formally other than nuclear tests. It was also the second time a Tsar Bomba was detonated after its development and its first official combat mission.


    It was just that at that time, the most destructive weapon invented by mankind was no longer used to kill and destroy, but to save mankind itself. It was ironic.


    The Tsar Bomba did live up to its name as the strongest nuclear bomb ever created by humans. Although the explosion did not set off a mushroom cloud in space, it swept the surface of the meteorite clean, like a broom.


    When the audience of the broadcast watched the stream of debris being blown away by the shock waves of the explosion, they cheered joyfully.


    Even in Chen Xin¡¯s group chat, everyone was astonished. They felt that there was still hope and the crisis brought by this meteorite could be resolved.


    ¡°Is this the legendary Tsar Bomba? I really love it. If only there was a picture of it!¡±


    ¡°What kind of situation are we in now? Why are you still fantasizing about your imaginary wife? If the meteorite really falls, there¡¯ll be a global power outage and you won¡¯t even be able to connect to the internet. There won¡¯t be any luxury for you to be fantasizing on your phone!¡±


    ¡°Compared with this, I¡¯m more concerned whether big shot¡¯s bunker could still take in others? I also have a bestie (pictures, pictures)¡±


    Chen Xin continued watching the live broadcast on the TV seriously as he ignored the messages from the group chat.


    When the nuclear bomb exploded, it blew open a gap in the pyroclastic flow that was large enough for two spacecraft to go through and land on the surface of the meteorite.


    As he watched the disappearing Team USA take advantage of this costly gap and plunge toward the meteorite¡¯s surface, Chen Xin could not help but feel nervous and paced around the room.


    He thought he had already looked past death, but when he saw the two spacecraft rush down without hesitation when the surface was exposed, Chen Xin inevitably felt anxious and worried.


    Could Team USA complete their task? Could the Tsar Bomba blow up this meteorite with a diameter of more than ten kilometers? Would the explosion disintegrate the meteorite into a pile of fragments?


    Those kinds of questions boggled Chen Xin¡¯s mind, which made him feel anxious and restless.


    At that time, most of the people in the world had shared Chen Xin¡¯s sentiments, but everyone was waiting. They were waiting for Team USA to detonate another Tsar Bomba and blow this meteorite apart.


    However, the wait felt like a lifetime. Every second that passed felt like gruesome torture to the six billion people around the world.


    It was as if they were awaiting their death sentence. You may be dead the next second, but you also might be alive.


    Still, it would take some time for Team USA to plant the bomb. If they wanted to blow the meteorite apart, they must first drill a hole big enough to plant the Tsar bomb.


    Drilling was quite a time-consuming job, which was why everyone ended up waiting. What worried the people was that communications with Team USA were disrupted because of the earlier explosion.


    Therefore at that moment, besides Team USA themselves, nobody knew the situation on the meteorite¡¯s surface.

 Chapter 11

    The two Team USA space shuttles disappeared on the surface of the meteorite. It was like the whole world fell into an indescribable silence.


    No one knew what was going on. The explosion of the Tsar Bomba caused a strong magnetic disturbance so the Earth already lost their connection with the three frontline spacecraft. The TV broadcast screen was filled with static, it seemed like even the broadcast director was petrified by what happened and forgot to switch the cameras.


    The unbearable silence went on for almost a minute but it felt like an eternity.


    The broadcast director remembered that he had to do his job, he cut the scene from static to visuals of NASA Federal Agency live reports.


    The two space shuttles were commanded by NASA because the spacecraft was from the United States.


    Everyone was desperately hoping for an explanation or a statement from NASA since they lost contact with the astronauts. They need something to calm their anxious heart.


    Chen Xin was nervous too but he convinced himself to stay calm. He expected the magnetic disturbance when the United States dropped a nuclear bomb.


    However, the magnetic disturbance would not last too long, the spacecraft was designed to combat this situation. Once the temporary magnetic disturbance was over, connections would be back online with the astronauts.


    That was what Chen Xin thought of. An expert who worked at NASA gave the same explanation on TV. He comforted the general public and hoped for their patience. He implored the general public to stay calm.


    Despite what the NASA expert said and how he acted, Chen Xin could tell he was not as confident as he looked.


    The NASA command center behind the expert was wrapped up in their work, it seemed like they fell into chaos.


    They expected this when the nuclear bomb dropped so they stopped panicking.


    The disconnection with the astronauts did not last long, Vermillion had already managed to reconnect with the Vermillion spacecraft.


    Space visuals from the spacecraft were back on screen. Chen Xin watched the screen attentively.


    There was an incoming meteorite as large as a mountain, its surface flared up with a streak of white light like a huge comet.


    Chen Xin knew the white flares were due to friction from the air, causing the surface of the meteorite to shed dust and debris. The United States dropped the nuclear bomb to avoid the pyroclastic flow coming from the meteorite. However, the pyroclastic flow was back in a short amount of time.


    Surprisingly, the connections were back online with Team Vermillion but not for Team USA.


    No one had heard anything from them ever since the two space shuttles went towards the meteorite.


    ¡°Are the two space shuttles goners? Why haven¡¯t we heard from them?¡± A few netizens from a Survival Groupchat that Chen Xin was in started to worry.


    It was possible. Although they avoided the pyroclastic flow with the nuclear bomb, no one knew what was the situation and no man had ever landed on a meteorite before. They might accidentally crash into the meteorite and die.


    There were another bunch of rational netizens who argued in the group chat, ¡°I think it¡¯s just the debris and all that disturbed the connection. According to the United States, they have to drill and set up a nuclear bomb on the meteorite¡¯s surface. It¡¯s not an easy mission so it¡¯s normal for them to take some time.¡±


    That netizen did drilling work as a profession. Although it was not as cool as drilling on the surface of the meteorite, he did dig wells at the Northeast so he had the right knowledge to comment on this.


    Chen Xin did change the group chat name into ¡®Survival Groupchat¡¯, the theme of the group chat was about survival. However, before the meteorite, the group chat was meant for a bunch of outdoor sports lovers.


    All outdoor sports lovers were decently wealthy and they were in diverse professions. The group chat members all had something up their sleeves, they could build their own apocalypse bunkers. None chose to use the official bunker provided by their government.


    The girl who seduced Chen Xin with the photo was underestimated. She claimed she did not have a bunker to stay in and wanted to move in with Chen Xin. However, she was well equipped. Chen Xin had a year full of emergency food supplies and other survival equipment, all because of the girl.


    Chen Xin was the only member who showed off his bunker to the group chat, but all other members had bunkers of their own.


    The girl who wanted to move in with Chen Xin had her own bunker now, Chen Xin could tell from the photo she sent of her with her sister and her bestie. Her bunker might end up being better than his.


    Her bunker could at least supply three people, unlike his bunker, especially when it was girls.


    ¡°I think it¡¯s a connection disturbance too. There are two space shuttles, it¡¯s unlikely that both of them crashed, right? We should be patient at a time like this.¡±


    ¡°I¡¯m feeling so anxious waiting for the news. It¡¯s like I knew there¡¯s a knife hanging above my head, but I¡¯m unsure whether it would fall on me.¡±


    ¡°Don¡¯t say that. Even if the meteorite strikes, as long as it doesn¡¯t hit on Team Vermillion¡¯s side, we would have a chance of survival in our bunkers. Author said so, right?¡±


    ¡°But what if we¡¯re unlucky? What if the meteorite strikes on our side?¡±


    ¡°Then we will rest in peace, no doubt about it.¡±


    Chen Xin sighed at the discussion in the group chat. His nickname was ¡®Author¡¯ in the group chat, he did say that if the meteorite landed on the United States, bunkered survivors could live.


    However, apart from himself, no one posted their bunker photos in the group chat. He was unsure whether they were fully prepared for the meteorite.


    He quickly sent a text in the group chat, ¡°It seems like I¡¯m the only person that showed photos of my bunker, are you guys prepared? Or are you guys choosing the Government bunkers?¡±

    ¡°Author, you¡¯re the first person to build a bunker in the group, I¡¯m almost done with mine too (Image attached, image attached) Right now I¡¯m moving my supplies in.¡±


    ¡°(Image attached, image attached, image attached) I already moved in, right now I¡¯m planting vegetables, I¡¯ll be down here until I¡¯m sure it¡¯s safe to come out. If the meteorite strikes, and if our life will be as our Author predicted, these vegetables might be the key to my survival! (Image attached, image attached)¡±


    This netizen was an agriculturist that did soilless culture. While everyone was discussing how to build a bunker, this netizen suggested everyone to build a greenhouse farm in their bunkers. The plants could provide oxygen through photosynthesis. Veggies, rice, and wheat could be a source for their food supplies too.


    Chen Xin thought it was a fantastic idea. That was why he built a greenhouse in his bunker. The greenhouse farm was about a hundred square feet.


    Although it was quite small, it could ensure his survival. It was still okay since it was just for Chen Xin alone, the production part was a bit worrying.


    Chen Xin had to continuously maintain the electricity and water source to keep his greenhouse running at the right temperature.


    ¡°I don¡¯t have a bunker yet, any of you big shots want to consider me? I can bring my sister and my bestie along. (Image attached, image attached)¡±


    She said she did not have a bunker yet, but the photos she posted were of three shy gorgeous ladies in a bunker.


    ¡°I suggest you all to not be wasteful. I can see everyone stored a lot of supplies, but when it comes to fuel, try to save up. You guys don¡¯t want to be looking for fuel in the freezing cold, right? Water is important too. Although we have a recyclable system for our water source, we should all still try to conserve on water,¡± A netizen said. This netizen is the true big shot of the group chat. He ran a tech company that produced this recyclable water system. It could turn air, soil, even human excrement into drinkable water.


    This technology was initially meant for airlines and space jets. The prototype was inspired by the recyclable system for water used in space stations. This big shot netizen created his version of the system meant for RVs. His technology could recycle the dirtied water from an RV into drinkable water making it very eco-friendly.


    The cost of the system was high so their company mainly targeted high-class RVs which classified it as a luxury product.


    However, the product was unexpectedly vital for a situation like this. With everyone building a bunker, their supplies would come to an end eventually. If they could recycle and reuse their supplies, their chances of survival would improve significantly.


    This big shot generously provided his company product to everyone in the group chat, he even helped everyone build their recyclable system for water in their bunkers.


    Chen Xin used the equipment provided too, it was effective and useful. He felt slightly grossed out at the idea of drinking water from feces and pee, but the equipment could indeed turn it into standard drinkable water.


    When the agriculturist suggested using soilless culture, Chen Xin came up with the idea of differentiating his water usage into two parts, a water system similar to an RV ¡ª used water and dirtied water.


    Used water meant the water he would use for daily life, dirtied water meant the water used in the bathroom.


    Recycling undrinkable used water was not as gross, Chen Xin decided for it to be his drinkable water source. He intended to recycle dirtied water for watering his plants.


    He could ensure his bunker has a stable water source this way.


    Time flew by while everyone was discussing in the group chat.


    An hour was a short amount of time for sixty billion people, but it was the toughest hour ever in human history.


    Everyone was about to give up. Suddenly, the meteorite shined brightly. A space jet dodged the debris and flew out from the pyroclastic flow.


    The space shuttle left with another Tsar Bomba, the United States completed its mission.


    Through visuals captured by the Team Vermillion Spacecraft, everyone could see what was happening on their TV screens. Chen Xin dropped his jaw and looked at the huge shiny meteorite glowing from within. It cracked in half. He was suddenly overjoyed.


    He could not help but screamed, ¡°We did it!¡±


    The meteorite exploded into halves. And it split apart according to the plan, with one half bigger than the other.


    Team USA had executed their mission successfully.


    There was only one space shuttle. What about the other one? What if¡­


    ¡°Houston, this is Space Shuttle Endeavour! We completed the mission, the nuclear bomb was detonated!¡± Live reports from Space Shuttle Endeavour could be heard on TV through NASA Federal Agency. They asked NASA loudly, ¡°Is the meteorite blown apart? Did we succeed in our mission?¡±


    They had no idea that the meteorite was split in half because they were busy fleeing from the explosion on the meteorite.


    NASA witnessed everything with the cameras from Team Vermillion Spacecraft. The expert who was interviewed by the reporters earlier immediately told them the good news, ¡°The meteorite was blown apart! Space Shuttle Endeavour! You successfully completed your mission! Congratulations, you¡¯re remarkable!¡±


    ¡°Really? We did it? Awesome!¡± Space Shuttle Endeavour cheered loudly, the astronauts were obviously thrilled to succeed in their tasks.


    The NASA experts noticed there was only one space shuttle. They asked, ¡°Space Shuttle Endeavour, this is Houston, where¡¯s Space Shuttle Atlantis? Have they returned from their route?¡±


    This question silenced the astronauts in Space Shuttle Endeavour. Half a minute passed before they answered, ¡°We were sucked in by the meteorite¡¯s gravity when we landed, we went off route and were forced to land. Atlantis crashed. The remaining survivors located us and finished the mission.¡±


    Chen Xin could not help it, he had a moment of silence. He paid his respect to the astronauts on Space Shuttle Atlantis. They saved the Earth by sacrificing their lives.


    ¡°Come on back, heroes.¡± Space Shuttle Endeavour finished telling the story of Space Shuttle Atlantis. NASA commanded them to come back, they would be in the international spotlight. A huge celebration awaited them.

 Chapter 13

    The success of Team USA encouraged Team Vermillion, sixty billion people on Earth cheered and celebrated too. Even Chen Xin was feeling confident after the success of the mission.


    Team USA completed their mission with their lives, the rescue operation was partially completed. If Team Vermillion succeeded with their mission too, the meteorite would be pushed off its course. The meteorite strike and the apocalypse would be avoided.


    At a time like this, everyone stopped what they were doing and watched their TV screens attentively. They paid attention to the people that tried to save Earth three hundred and eighty thousand miles away.


    Team Vermillion fired up their spacecraft. The debris was blown away from the explosion, leaving the meteorite¡¯s surface exposed. The Vermillion Team quickly went towards the meteorite through a gap.


    Maybe it was the meteorite or the EMP (electromagnetic pulse) shockwave caused by the nuclear bomb explosion, the signal was weak when they nearer the meteorite.


    Everyone could watch the meteorite clearly from the camera on the spacecraft. They watched the visuals turned from a big mountain-like meteorite in the universe into terrain on the surface.


    Chen Xin was astounded, it was not something you would see every day on Earth.


    The Vermillion spacecraft installed a wide-angle lens, so the visuals captured were wider than a normal camera lens making it look more astounding and impactful.


    The surface of the meteorite was bumpy with craters caused by impacts by space debris. Some thought it looked like a burnt cake.


    No one would find this humongous ¡®cake¡¯ appetizing though.


    Even if the United States blew the meteorite apart, the two halves of the meteorite were still relatively large. The visual impact of watching it through the Vermillion spacecraft camera was an indescribable feeling.


    If it had to be described with a metaphor, it would be as if the Himalayan Mountains were falling from the sky.


    Chen Xin could not help but wonder, if the meteorite strikes, could humankind even survive?


    He built his bunker and prepared his food and water supplies. He considered every aspect and was ready for survival. However¡­ there was a deadly threat Chen Xin could not prepare for.


    Unfortunately, their chances of survival depended solely on their luck, and whether the meteorite would strike directly on them.


    The meteorite was not as huge as it once was, but it would still cause tremendous damage. Chen Xin knew if the meteorite crashed in Asia, his chances of survival were slim to none.


    He was scared and frightened he when looked at this huge impending rock of doom.


    As an imaginative sci-fi author, a meteorite strike was not worth mentioning in his web novels. It caused Chen Xin to lack a sense of danger upon this disaster.


    He did his best to prepare for the apocalypse, he stored supplies, built his bunker, and was ready for survival¡­


    However, he did not have an exact concept of what would happen if a meteorite strike did indeed occur.


    Hypothetically, it was like a tiger. Everyone knew a tiger is dangerous, but they would not know how dangerous it was until they witnessed a tiger eating a man alive. This caged animal in the zoo was like a big soft kitty, chubby and lazy. They forgot it was a fierce beast.


    Humans would only be scared when faced with danger.


    Chen Xin was the same. He prepared for the apocalypse calmly. He was feeling scared now that he saw the meteorite.


    Well, scared was not the right description, Chen Xin was terrified of death.


    You could imagine how much pressure the astronauts were under.


    The astronauts in the Vermillion spacecraft fearlessly flew towards the meteorite, the lives of sixty billion people depended on them.


    The astronauts from the United States made a forced landing on the meteorite surface look easy. It then struck the astronauts from Vermillion on how difficult it was.


    Although the debris was out of the way, it was still extremely dangerous to land on a meteorite.


    Some debris might hit them if they were not cautious, the spacecraft could be damaged, or even worse, crash into their ultimate demise.


    Thankfully, the Vermillion spacecraft was designed to be more agile than the USA Space Shuttle. The astronauts were well-trained with flight simulations too. They landed successfully with only a few scratches on the paint and a few antennas gone. All things considered, it was a good landing.


    The landing was the first step. Now, the astronauts had to carry out their assignments by stepping out of the spacecraft. Their mission was to ensure the main body part of the spacecraft ¡ª a specially made booster and its fuel tank were connected and secured to the meteorite surface. The rest of their mission was to manually push the meteorite off its course.


    Their landing spot was carefully calculated to ensure the booster had an accurate pressure point to push the meteorite in the right direction. If the booster worked but the meteorite was pushed in an unexpected direction, it would be all for nothing.


    Fortunately, Team Vermillion landed on the right spot. Despite losing a space shuttle, the rescue operation was going according to plan so far.


    All they had to do was activate the booster and use the help of the gravitational pull from the moon, the meteorite would be out of the way and Earth could avoid the apocalypse.

 Chapter 14

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    Three astronauts stepped out of the spacecraft and started working with their tools.


    The time was limited for the meteorite to pass through the orbit of the moon. If they wanted to push the meteorite off its course with the gravitational pull of the moon, every second counted.


    They watched the astronauts in their heavy space suits through their TV screens. As they worked, Chen Xin prayed and rooted for them.


    Unlike Team USA who lost their connection, Team Vermillion had a slightly better feed throughout the whole process, meaning people from Earth could still track their progress.


    The TV stations provided some narration too where the narrator explained what the astronauts were doing. The audience could listen to the live news, and based on the narration, they better understood what the astronauts were doing and how far they were progressing.


    Team Vermillion had an easier mission in comparison to Team USA. Team Vermillion only had to drill and secure the booster. Team USA however, had to drill a hundred-meter hole for the nuclear bomb.


    Although they needed to drill more holes, it was a relatively easier task. The three astronauts worked together and managed to complete their drilling in a short amount of time.


    When the astronauts were done, Chen Xin and the TV audience became agitated. Even the broadcaster said in an excited voice, ¡°Alright! The drilling is completed! Next, all that¡¯s left for the astronauts is to install the screws. Once the screws were installed, the astronauts would have completed all their tasks, they could go back into the spacecraft and initiate the booster. The meteorite would be pushed off!¡±


    Chen Xin stood up upon hearing the news. He watched the astronauts install the screws clumsily because of their heavy spacesuits. He could not resist his urge to reach out through his TV screen and help them tighten the screws.


    He was far away so he could not do anything but worry.


    Luckily the astronauts were prepared for the screw installation before they set off for their mission. They had a professional drilling tool that helped them install each screw within a second. Plus they were working together, so the screws were quickly installed. Sixty billion people watched them complete their mission.


    The commanding officer at NASA hastily grabbed the microphone and yelled at the astronauts, ¡°Return to the spacecraft immediately! Initiate the booster! Leave the f*cking equipment behind!¡±


    The TV station cut to the old commanding officer with white hair. Chen Xin looked at him on his TV screen and wondered if his heart could handle the strain at his age.


    It was understandable why the commanding officer yelled since Chen Xin wanted to scream at the astronauts too. He wanted to tell them to ignore the tools and hurry up with the booster.


    Every second mattered. The sooner they got onto that spacecraft, the sooner they would be able to push that meteorite off its course and save the world.


    When it came to saving the Earth, tools and gadgets meant nothing in the rescue operation, especially when a billion-dollar USA space shuttle was sacrificed in the process.


    The astronauts followed their orders. They checked the screws then immediately ran towards to spacecraft. They then quickly activated the booster.


    The custom made booster fired up and the spacecraft separated, leaving the meteorite surface.


    The USA space shuttle could take off easily because their nuclear bomb cleared away the pyroclastic flow, unfortunately, the Vermillion spacecraft had to face incoming debris.


    Fortunately, the booster helped cleared a gap for them to fly through. They were back in space and were joined by the Space Shuttle Endeavor. Both of them began their return to Earth.


    Meanwhile, the meteorite changed course from the thrust generated by the booster and the gravitational pull of the moon.


    ¡°Thanks to the bravery, heroic sacrifices of our USA and Vermillion astronauts, the meteorite is moving away from Earth. According to scientists, the meteorite will be pushed off its course within a few hours. In the next few days, the meteorite will no longer hit Earth, the fate of humanity is restored!¡±


    A good-looking female reporter almost cracked her voice from cheering. Chen Xin cheered loudly too. Although it meant his preparations were all for nothing, it was all worth it. All he wanted was Earth to be saved and for humans to continue living under the warm sunlight.


    He cheered and celebrated until he lost his voice. Chen Xin calmed down when he felt thirsty.


    He noticed the TV station missed out on mentioning something important. The meteorite was blown into two halves. The one meteorite that was pushed off its course was the big meteorite half, but what about the smaller half?!


    Chen Xin ran to his laptop and checked for the latest news. He simultaneously switched the TV news channels.


    However, the TV stations were all about cheering and celebration. The TV audience relaxed as if the danger was completely removed. It disappointed audiences like Chen Xin who wanted to be informed on important news.


    Thankfully, the Internet would provide the information he needed. Some netizens asked the same question on the smaller meteorite. Would the small meteorite crash into Earth?


    Someone replied with facts and evidence, ¡°The Russians will blow the smaller meteorite into bits with a nuclear bomb.¡±

 Chapter 15

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    ¡°We Russian are invincible in space! Huzzah!¡± chanted the Russians while they launched their spacecraft along with twenty powerful nuclear bombs from the top five nations of Earth.


    Their mission was to stop the smaller meteorite from crashing into Earth with nuclear bombs, therefore, the launch route was different from the usual parabolic orbit. The nuclear bombs could not be activated from Earth because of the ozone layer which meant the Russians carried the bombs with them to space.


    The two meteorite halves were moving in different directions but at the same speed towards Earth.


    The bigger half would miss Earth completely because of the booster. However, the smaller meteorite would still crash into Earth.


    It was an expected result, the third part of the rescue operation depended on the Russians who needed to attack the smaller meteorite with their bombs until it was blown into bits.


    The smaller meteorite measured around four kilometers in its diameter.


    It was smaller in comparison with the larger chunk, but if it crashed, a part of Earth would be destroyed.


    They could not allow this to happen.


    The best solution was stopping the smaller meteorite in outer space.


    A nuclear bomb was the most powerful weapon ever invented by humans. But it worked differently from outer space.


    When a nuclear bomb was launched on Earth, an explosion would occur along with lasting radiation damage.


    However, there was no air in outer space. A normal explosion would not occur in a vacuum plus, there would be no mushroom cloud.


    Honestly, the radiation was not a concern since the nuclear bombs nowadays were radiation-free. The world learned well from the mistakes of Chernobyl.


    Moreover, there was radiation all over space anyway.


    The nuclear bombs were still immensely powerful since it was the pinnacle of weapons research from the nations of Earth.


    It was powerful enough to blow the small meteorite into bits.


    It was the reason why every nation was in a more relaxed state.


    They believed they had already saved the world, this mission was a piece of cake for the Russians.


    It was a risky decision to announce the danger was over, but it was a decision they had to take. The previous disasters put nations in a perpetual state of panic.


    All nations suffered economic and social losses in previous disasters. Most smaller nations even fell into a state of chaos.


    Especially in Southeast Asia and Latin America, those countries fell into a government-less state. Anarchy reigned there like it was the end of the world.


    Every nation hoped for the natural disasters to be over so they could spend money and effort on rebuilding their countries.


    As for the capitalist nations, it was better if they could announce a danger-free situation so they could hurry up and rebuild their countries. That way they could benefit from it, it was what politicians only cared about.


    They were spreading propaganda that the danger had passed through the media. So they could calm the people and lead things back to normal. Losses would be huge if people were in a state of panic.


    However, the top five nations were still on their toes. They knew there was a possibility that the meteorite could still crash into Earth.


    They risked it all for the first two parts of the rescue operation. Every nation did not have the time to calculate the meteorite¡¯s mass and orbit, they just chose their best weapons and boosters.


    The scientists, commanding officers, and the astronauts had no precise clue about the effect of the bombs.


    The big meteorite was pushed off its course, but it was not yet over.


    When it passed through the orbit, it might change its route due to the gravity of the Earth¡­


    If it did not miss Earth, the consequences would be detrimental.


    The United States operation squad were on guard at all times, observing the larger chunk and calculating its route non-stop. They were supported by data provided from Russia too, all they could do was pray that no unexpected accidents would occur.


    They were out of options to deal with the larger meteorite piece if anything untoward happened.


    All remaining nuclear bombs were to be used against the small meteorite. They no longer had any cards to play should a backup plan be needed.

 Chapter 16

    The US government did not allow the citizens in the government bunkers to come out because they were worried that the danger had not yet passed.


    They hurriedly built the bunker before the meteorite could pass by Earth. They wanted every citizen to be sheltered safely.


    Meanwhile, the United States government also ordered for their power stations and water plants to be upgraded and secured. They want to ensure their bunkers could survive a possible disaster.


    A meteorite crash might cause an earthquake, fire, and a series of other natural disasters.


    The citizens would not stand a chance of survival if their facilities failed.


    Chen Xin wholeheartedly agreed with the actions of the USA government. The news stations were reporting only good news, a lot of other countries were celebrating. Some cities even had parades. Chen Xin felt like it was not over yet.


    He stuck to his plan and moved his supplies to his bunker.


    However, Chen Xin was not ready to move in yet. His underground bunker did not have an internet connection so he was not able to receive the latest news.


    It was unacceptable for Chen Xin.


    He would not be able to know if doomsday was coming, where the meteorite would strike, and whether it would be dangerous or not to stay above ground¡­


    Chen Xin could not stay in the bunker and wait without information, that was not his style of doing things.


    He was the type to take charge, like how he took charge when building his bunker and upgraded his facilities then stocked up on supplies. He was the type to face his problems head-on.


    Even if the meteorite struck upon him, he would be the type to point his middle finger at it and yell, ¡°Motherf*cker!¡±


    He would not hide like a turtle in its shell and await his fate.


    That would make him feel like his already insignificant life depended on others, staying in his bunker would not make him less insecure.


    Unlike the netizens in his group chat, Chen Xin chose to not move into his bunker yet.


    He might be able to install a few antennas in his bunker so that he could receive an internet connection, broadcast news, or something. Chen Xin thought about it but decided to discard the idea.


    It was not because it was troublesome to listen to the news in his bunker, but instead, Chen Xin felt like it was unnecessary to install antennas.


    According to his calculations, the EMP shockwave caused by a disturbance in the ionosphere would wipe out electronic devices and equipment anyway. The fragile antennas would be the first outdoor device to be destroyed in the first wave of disasters.


    He instead prepared a shortwave antenna that would still work under freezing temperature. This high-class equipment was usually hard to get.


    Chen Xin pulled some strings to get two Russian military-grade antennas. Obviously, he could not waste it by installing it now. He wrapped it securely in aluminum foil and placed it in a big metal case, he decided to install it after the meteorite crash.


    Chen Xin learned to reduce the EMP shockwave by wrapping it in aluminum foil from movies. It was not as good as placing it in a microwave, but it was good enough to protect it.


    The big metal suitcase was going to be in the underground bunker regardless, so the protection was good enough.


    He packed and sat in front of his TV while still scrolling on his phone for the latest information. His laptop was already moved to the bunker.


    The TV stations were still broadcasting live from NASA and the rescue operation. Although it was still a global broadcast, the news content now showed broadcasters in their respective studios. Unlike previously when they only showed visuals from NASA and the spacecraft.


    Meanwhile, the Russians had arrived at their destination, they were ready to face this meteorite.


    The broadcaster and the invited expert displayed a rather positive attitude, even Chen Xin felt optimistic towards the rescue operation.


    The Russians activated the twenty nuclear bombs, never in history had so many nuclear bombs been detonated at the same time.


    It seemed assured that the small meteorite would be blown to bits.


    Chen Xin was excited to watch the Russians do that. Suddenly, the NASA control center erupted in chaos. The Russian spacecraft abruptly stopped their attacks.


    Chen Xin did not understand what was happening, he switched to a few channels to find the same situation.


    He was confused. However, the live reporter on TV seemed to have figured it out, the live reporter went pale and said to the camera, ¡°The bigger meteorite that was pushed off its course was affected by Earth¡¯s gravity. It broke down into smaller meteorites and they are heading towards Earth!¡±

 Chapter 17

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    When gravity pulled on an object from outer space, and the said object had a different gravitational source, it would be torn apart. The difference in their gravitational source was also known as a tidal force.


    Using the same concept, it could be said that a tidal force was everywhere throughout the universe.


    As long as something had a large mass, there would be a gravitational source.


    The burning sun, the Earth, the moon, and the other planets were gravitational sources.


    A tidal force would not be able to tear objects apart under normal circumstances. Take Earth as an example.


    Earth was moved by the sun and affected by the moon. Tidal waves in the ocean was a phenomenon from the tidal force of the moon, yet Earth had not been torn apart despite being between two tidal forces.


    However, the meteorite was different.


    First of all, it did not have a huge mass, it was affected by the moon, the Earth, and the sun.


    Secondly, it was initially strong enough to not be torn apart. But then the astronauts drilled along its center with the explosion.


    The core of the meteorite was unintentionally damaged when they cracked the meteorite apart.


    The meteorite would be fine if they just left it as was when it was first discovered.


    Metaphorically, the meteorite was like a bedsheet. If three people pulled on the bedsheet, the bedsheet would not be ripped apart. If the center of the bedsheet had a huge hole, it would still be fine. However, if the bedsheet had a hole in the center and three people pulled on it, it would be easily ripped along with where it was damaged.


    Using the same concept, the meteorite separated into three smaller chunks due to gravity.


    The worst part was, due to their lighter mass, they were easily captured by the planet¡¯s gravity meaning they were now headed towards Earth.


    A meteorite crash was an insignificant event when it came to the entire universe. Earth was just a speck of dust.


    Truthfully, some small asteroids and meteorites have crashed into Earth before. Usually, they would land in the middle of nowhere or they would be burned to ashes because of the ozone layer. This meant very few meteorites made it to the surface of Earth.


    A human civilization with sufficiently advanced technology would have their ways to combat this kind of natural disaster, they would still find a way to survive.


    What if a meteorite crash occurred in a civilization with less advanced technology?


    One would not need to go back too far, take the eighteenth-century for example. If this meteorite happened upon Earth two hundred years ago, humans could say the same thing as dinosaurs did, ¡°Goodbye.¡±


    The steampunk era was not technologically advanced enough to combat a natural disaster like this. They would not able to build a sufficiently strong bunker.


    Modern civilization had its limits too.


    They used up all their weapons to deal with the meteorite. They thought the bigger meteorite was out of the way, but now they have three smaller meteorites to worry about. The presidents of the nations were all immensely pressured now.


    The broken off meteorite chunk had not yet been dealt with by the Russians, yet now they faced three additional meteorite chunks from the larger one. It was like their hard work was all for nothing. Doomsday was impending and it got worse.


    At a time like this, the presidents wanted to curse, ¡°What the f*ck?!¡±


    However, they could not give up and wait for their doom. They called an emergency meeting and try to come up with possible solutions.


    ¡°So far there are four meteorites incoming at 11.5 kilometers per second. They are expected to crash into Earth within a few hours,¡± said a scientist from the USA operation squad. The scientist reported to the presidents about the location too, ¡°According to calculations, the meteorites would most likely crash on North America and the Pacific Ocean.


    The scientist did not speak of the ensuing disasters after the meteorite crashed. Everyone had a rough idea of what would happen, they were facing extinction like the dinosaurs.


    The priority right now was to stop the four meteorites.


    At least stop them from crashing all at once.


    ¡°What can we do to stop the meteorites?¡± asked the President of the top five nations on Earth.


    ¡°Truthfully, we don¡¯t have any solutions. We can¡¯t launch a spacecraft in a mere few hours, that¡¯s not enough time, we can¡¯t even finish refueling one on time. Plus we don¡¯t have any spaceships left,¡± said Britain¡¯s president with a long face and a heavy heart.


    Britain had run out of options, they had limited sources for a global crisis like this.


    The President of Russia disagreed, he said affirmatively, ¡°We still have something up our sleeves! The Russian spacecraft is still in space, we can use the twenty nuclear bombs to blow them up!¡±


    Every eye in the meeting lit up with hope. It was their last chance at saving humanity and the last thread of good news.

 Chapter 18

    If the Russians initially intended to attack one meteorite, all they had to do now was change their mission into attacking four.


    The other scientist from the operation squad said, ¡°Twenty nuclear bombs was enough to blow a meteorite into bits. However, we¡¯re facing four different meteorites with different orbit routes! The Russian spacecraft can¡¯t aim precisely at four meteorites at the same time.¡±


    ¡°They can either go for the initial meteorite or go for the three torn meteorites, they have to pick one of these options! The initial meteorite could be easily destroyed, but they might miss the remaining three.¡±


    The scientists lost hope.


    The Russians couldn¡¯t stop all four meteorites at the same time since they were going in different directions.


    After a minute of uncomfortable silence, the President of the United States asked the scientist, ¡°Can you identify which meteorite is going towards North America? If it¡¯s possible, we have to prioritize destroying it with nuclear bombs! We have to ensure the safety of North American citizens! If we can¡¯t stop the meteorite heading towards the Pacific Ocean, then we should give it up! May God bless those innocent souls!¡±


    His words were cold and cruel, the Americans were shameless. They would sacrifice the other countries to ensure the safety of their own.


    The scientist answered despite the moral ambiguity, ¡°The meteorite heading towards North America is the meteorite that the Russian spacecraft was originally ordered to attack. According to the calculations, the three torn meteorites were heading towards Australia and Hawaii.¡±


    The USA president was overjoyed at hearing that, he said loudly, ¡°Alright, let the Russian spacecraft continue with their mission, destroy the first meteorite chunk! If the Russian¡¯s bombs are not enough, the United States will launch more!¡±


    It seemed like the president chose to ignore the three remaining incoming meteorites. He only cared about the one headed towards North America.


    The citizens in the Pacific Ocean region did not even have government bunkers, why would he care about them?


    It was cruel, but it was a sacrifice he was willing to make. He would not hesitate to sacrifice the Pacific, a few small countries, and Australia if it meant he could save Earth.


    He was arrogant, the other presidents thought his actions were unacceptable.


    The Australian president was in the meeting too, he wanted to punch this shameless American *sshole, politely ¡®ask¡¯ how his family were doing, and then f*ck his wife and daughter.


    Before he could say anything, the head of the scientists spoke up, ¡°That would be such a waste! It is illogical for us to use twenty nuclear bombs against one meteorite. If a choice had to be made, we should choose to attack the three meteorites heading towards the Pacific Ocean!¡±


    ¡°That meteorite will destroy my city! Think about all the casualties on American citizens! We should choose to attack the one meteorite. Ignore the three meteorites, not a lot of people would be dead anyway!¡± His shamelessness was showing.


    The Russian president was extremely upset hearing those words, ¡°I will order my astronauts to destroy the three meteorites heading towards the Pacific Ocean. As for the meteorite heading towards North America¡­ let¡¯s just say the nuclear bombs belong to the former Soviet Union.¡±


    The USA president choked on that, he pointed angrily at the Russian president and cursed, ¡°That is murder! Millions of innocent American citizens will die by your hands! They will die because of you! You murderer!¡±


    The President of Russia remained calm and indifferent.


    It was the end of the world. Pretty soon, most Americans would be dead. What could he do? Call him cruel? He would be dead by then.


    The USA president was dropping ¡®f-bombs¡¯ left and right. He simply ignored him. The head of the scientists supported his decision, ¡°Truthfully, going for the three meteorites is our only choice. The damage will be worse than one meteorite. If the three meteorites crashed into the Pacific Ocean at the same time, it would be the apocalypse.¡±


    The statement from the scientist changed the minds of the rest of the leaders, they suddenly all supported the Russian president.


    The American citizens were innocent, the head of the scientist did not want to see the end of America so he added, ¡°We don¡¯t need twenty nuclear bombs to destroy that one meteorite. Let it get closer to Earth, the USA could launch a nuclear bomb and blow it into bits.¡±


    He knew it was a risky decision. Usually, a bomb launched from the surface did not have navigation, it could easily miss the meteorite.


    The Russian spacecraft was carefully designed to have bomb navigation, they could hit their target with precise aim.


    Not all the presidents agreed to that advice, but the scientist said something that all of them agreed upon, ¡°The United States is the best military nation, right? You have a lot of nuclear bombs. The United States national missile defense can stop missiles, a meteorite shouldn¡¯t be a problem with your capabilities, right?¡±

 Chapter 19

    Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation


    Chen Xin did not know about the USA missile defense system that the Americans were so proud of. All he knew was the impending doom of the meteorites.


    The female reporter that was acting optimistic on TV just now was now forcing herself to act calm. She looked serious and slightly terrified.


    The twenty nuclear bombs were initially prepared for that four-kilometer-radius meteorite. It was excessive but it was sufficient to destroy it.


    Now the Russians had a change in plans. Their mission was to change their route towards the three torn meteorites which were falling at high speed towards Earth. The difficulty level of their mission became significantly higher.


    Chen Xin was not a pro at astronomy but he knew the Russians had a low chance at stopping all three meteorites at once.


    They could probably stop one or two but it was too difficult to successfully aim at all three.


    In the previous live broadcasts, the reporter purposefully repeated that the nuclear bombs were navigated at the initial meteorite with precision and calculation. They repeated that to boost the confidence of the citizens.


    The Russians only had to aim and fire the bombs.


    Plus there was only one target, so they could easily fire away.


    They could hit two targets as long as they were not in the front and back of each other.


    However, they were now facing three targets doing the Brownian motion. They were moving in random directions towards Earth!


    If one of the meteorites ended up in front of the other two, all the twenty bombs would fire at the same time, leaving the two meteorites in perfect condition!


    In conclusion, hitting two meteorites was the best possible outcome!


    As for the meteorite heading towards North America, Chen Xin had little hopes for that. It was out of the question.


    The missile interception system that the Americans were so proud of was actually a defense system. It was designed to intercept missiles launched by other countries.


    A missile should not be in compared with a meteorite. It was easier to aim, but it was not powerful enough. Intercepting a missile required one or two missiles, but to stop a meteorite? They need everything they got. It was way more difficult.


    They were also using normal missiles, the Americans were unsure whether they could stop the meteorite in time without more firepower. The United States had no choice but to use multiple missiles.


    There was another problem, the destroyed meteorite debris would also potentially be contaminated with radiation, meaning it could spread all over the ozone layer!


    Only North America would be contaminated if they were lucky. If they were not, the whole world would become an irradiated wasteland.


    Chen Xin thought of the worst-case scenario for humanity.


    He packed his TV with his sleeping bag, then tied it securely with ropes. Chen Xin took one last look at his home, said his goodbyes, then headed straight toward his underground bunker.


    There was no chance he would return to his home. Even if he did, he would not be living here anymore.


    These thoughts upset Chen Xin, he was sentimental for a few minutes before he held onto his TV and sleeping bag. He locked the door and left his house.


    The bunker would be his new home.


    His phone was still broadcasting live on his way to the bunker. The Russians already opened fire. The meteorites were covered and nowhere to be seen.


    Chen Xin stopped dead in his tracks.


    Maybe, just maybe, the nuclear bombs could stop the meteorites.


    He did not need to move into his bunker if the meteorites were destroyed, right?


    Chen Xin prayed to the Gods and spirits that watched over humanity. He prayed for some luck at the last chance to save the world.


    The fate of the world depended on the twenty nuclear bombs.


    It was ironic that the weapon meant for destruction was their last hope of survival.


    Everyone prayed and hoped that the nuclear bombs would blow the meteorites into bits.


    The first nuclear bomb hit a meteorite, it shined brightly like a bright spark in the universe.


    Chen Xin looked up and saw the light in the sky caused by that nuclear bomb.


    More sparks followed, his phone screen was shining a bright white light. It was like the biggest fireworks display in the sky, caused by the greatest weapon ever invented by humans.


    It shined like a foreign sun.


    ¡°Is it gone?¡± Chen Xin stared at the sky. He did not care about the dazzling light hurting his eyes, he needed to know what was the result.

 Chapter 20

    ¡°Is it gone?¡± The president of the United States asked the same question just as Chen Xin said it.


    However, he was asking about the meteorite heading towards North America, the one that the Russians were originally going to destroy.


    They launched another bomb to stop the meteorite. Five powerful war bombs were used in total.


    The explosion wiped out their radar and equipment completely. They had to wait for the results.


    ¡°I¡¯m sorry Mr. President, we can¡¯t tell what¡¯s going on right now, all our equipment is down,¡± reported one of the soldiers. He had never seen an explosion from five war bombs before too.


    He immediately ordered the other soldiers to fix their equipment.


    Soon, one of them rerouted the surveillance equipment and managed to get a visual in the government bunker. A huge fireball was seen burning up in the sky.


    Everyone was electrified by the scene, it was burning because the bombs hit the target.


    Someone asked confusedly, ¡°Wait, that¡¯s the effect of five war bombs?¡±


    A war bomb might not be as powerful as a nuclear bomb but it was still powerful. There was something wrong with the way it looked, something was off about the size of the meteorite.


    Just when everyone was confused, there was a fiery meteorite shower striking the ground out of nowhere.


    ¡°What is that?!¡± Everyone was on edge, they hurried up to try and figure out what was going on.


    More burning meteorites struck the ground, it was a raining disaster in North America.


    ¡°Holy f*ck! Can somebody tell me what¡¯s going on?!¡± The USA president dropped a few f-bombs.


    However, it did not work. He was not the Hulk, he could not solve things just by being angry.


    He cursed angrily and threw all his manners into the ditch but still could not figure out what was going on.


    He was about to smash something when someone finally pointed it out.


    ¡°Mr. President, I figured it out! The bombs didn¡¯t explode at the same time. There are only two bombs that successfully exploded on the meteorite, the other bombs went off before they could hit the meteorite,¡± he hastily explained.


    A situation like this was expected, they launched so many bombs to ensure they hit their target at least once. They did not expect that all the bombs would explode at the same time.


    It was still an acceptable situation.


    ¡°Then what about the meteorite shower? Is it debris from the meteorite?¡± asked an associate standing next to the president.


    ¡°Yes, it¡¯s meteorite debris! The bomb exploded on the meteorite, but it did not blow it into bits! According to NASA, we have a lot of incoming debris heading our way, one of them has a diameter of one kilometer!¡±


    ¡°What?!¡± Everyone in the bunker panicked.


    Meteorite debris was not a big deal, only the buildings would be hurt, it would only be troublesome to rebuild them afterward.


    However, a meteorite with a one-kilometer diameter was destructive enough to eliminate the United States!


    Scientists once discovered a meteorite crater in Greenland with a diameter of thirty-three kilometers. It was hit by a meteorite exactly like that! According to scientists, everything in a seven-kilometer radius of the surface was cratered!


    The crash was not the worst part. The worst part was the series of disasters that would ensue.


    ¡°Mr. President, what should we do? Please give us orders,¡± a soldier looked at the president. It was time for the chosen president to make a decision.


    Everyone looked at the president and awaited his orders.


    He took a step back and almost fell.


    He held on to a table to steady himself. He looked at everyone in the bunker and asked, ¡°Can we stop the meteorite with bombs?¡±


    ¡°Sorry Mr. President, it¡¯s too late,¡± answered one of the soldiers.


    The president blacked out at that, he put his hand on his forehead and took a deep breath, ¡°Use all channels to release this news to the world! Let every citizen take shelter, calculate the meteorite landing location from NASA at the same time, do everything we possibly can to evacuate¡­¡±


    He had trouble breathing, he stopped for a while then continued, ¡°I announce that the United States of America is hereby in a state of emergency. Go to Defcon 1. We are on a war footing, the whole nation should be on guard. Every government, every military soldier, and every policeman should do their job and keep an orderly society¡­ until we get through this.¡±


    Everyone listened in silence, it was depressingly awful. A female staff bit her lip and held on to her shirt collar nervously.


    Finally, the USA president gave his last order. He looked at the silent bunch and sighed, ¡°I shouldn¡¯t say this as the President of the United States at a time like this but, may God bless America.¡±


    He grabbed a nearby chair and sat down. The others asked his associate, ¡°What about the Russians¡¯ mission? They sacrificed the United States, did they manage to save the rest of Earth?¡±

 Chapter 21

    The Russians did not succeed in their mission. The interception had failed, or only part of it succeeded.


    As predicted, the nuclear blast shattered one of the three meteorites. Although it also hit the other two, it did not destroy them. It only burnished their surfaces. Those remaining meteorites were still falling toward the Pacific Ocean.


    According to astronomers¡¯ estimates, they would fall between Australia and Hawaii.


    Even so, that had nothing to do with Chen Xin. No matter where the meteorites fell, with a diameter of five kilometers, they were large enough to cause a global disaster. The impact would set off a cloud of dust, obscuring the sky, and drag the whole world into a long and cold night.


    All that Chen Xin could do at that point was to take one last look at the bright, sunny world, and then quickly seek refuge in his bunker.


    He had to do so because there would be no more sunlight on the surface for the next dozen or even hundreds of years. It was very likely that that would be the last time Chen Xin would see the sun in his life.


    At that time, in addition to the sun, there were two huge fireballs blazing through the sky at a very high speed, flying toward the east.


    Along the trajectory of those huge fireballs, little like sparks flew out from time to time, leaving a long, bright trail across the sky.


    Chen Xin knew that those were the two meteorites that were about to hit the Earth. Those sparks that the meteorites gave off were nothing more than fragments that peeled off from the meteorite burning up due to atmospheric friction.


    When those two meteorites crashed, the Earth would face another mass extinction, just like the fifth mass extinction that occurred at the end of the Cretaceous period 65 million years ago. More than 80% of the life on Earth would die, and the entire ecosystem would collapse.


    Whether the fate of mankind would be the same as the dinosaurs that ruled the Earth back then, Chen Xin did not know.


    If human beings could survive that crisis, then there was still a chance to rebuild their homeland.


    If not, then humans would become a stepping stone at the feet of a new generation of terrestrial overlords, much like the extinction of dinosaurs gave way to the mammals¡¯ dominance.


    However, matters that pertain to the fate of the entire mankind were too far out for Chen Xin to consider. What he needed to do then was to quickly enter his bunker and try to survive.


    ¡°Hey everyone, I have entered the bunker. If everyone manages to survive, let¡¯s keep in touch using the shortwave radio, and please use the channel that we agreed on before.¡± Chen Xin sent the last message in the survival group chat as he saw everyone talking about the same thing. He thought about it, then added another message: ¡°Live long and prosper.¡±


    That was a Vulcan salutary greeting from the movie ¡°Star Trek¡±, but then Chen Xin felt like there were no words of blessing more suitable.


    Faced with the imminent crisis, what mankind needed the most was the vitality and resilience to prosper again after the disaster.


    Just as Chen Xin sent that message, everyone in the group chat reciprocated similarly and planned to enter their bunkers with their belongings. Suddenly, there was a roar in the sky similar to the sound of a jet engine flying overhead.


    Chen Xin quickly looked up, only to see a red flame in the sky approaching his location.


    It was a meteorite!


    Chen Xin picked up his pace, hurriedly put away his mobile phone while holding the TV set wrapped in a layer of bedding, and ran towards the bunker. He could not help but regret it, why did he take his own sweet time!


    Could humans outrun meteorites?


    That question was difficult to answer.


    The fastest record for men¡¯s running speed at that time was 36.86 kilometers per hour. That was not considered slow, but the velocity of meteorites could easily change the unit of time into seconds. Many objects in the universe traveled at a velocity of tens of kilometers per second.


    Unless you were a superhero or cartoon character with special abilities such as The Flash or Quicksilver, there was no way human beings could even come close to outrunning meteorites.


    However, if one simply avoided the impact of a meteorite, as long as the volume of the meteorite did not exceed a certain limit, one could still travel out of the impact range and avoid being pulverized.


    Chen Xin was a little unfortunate. When he was approaching the entrance to his bunker, the meteorite that was en route to his location had landed.


    Fortunately, Chen Xin was not hit directly. The shockwave of the impact swept him off his feet, and he fell to the ground along with the bedding-wrapped TV set that he was carrying.


    The blast caused an uncomfortable ringing in Chen Xin¡¯s ears. He held his head firmly, and it took a long time before he recovered.


    Looking at his scratched palm, feeling the pain of his whole body from the shockwave, he was not in the mood of cursing or rejoicing.


    A little embarrassed, Chen Xin got up from the ground and checked whether the TV set was broken, and he was relieved.


    As luck would have it, there were pillows wrapped inside the bedding, and the TV was not damaged.


    Chen Xin wrapped the TV up again and opened the door to the bunker. He stood at the door and hesitated, then put down the TV, turned around, and stumbled toward the direction of the crash site.


    Since the meteorite hit the ground and caused an impact, there was a huge chance it did not completely burn up in the atmosphere.


    At that time, the meteorites that could crash into Earth were fragments of the two larger meteoroids in the sky, even if they were not part of the original meteoroid that spanned a diameter of ten kilometers.


    To Chen Xin, it seemed like a good idea to pick up a fragment of that meteorite as a souvenir, since it was going to bring about the end of the world.


    If it were under normal circumstances, Chen Xin would have not followed through with that idea.


    However, that one in million chance scenario would only happen when the whole world was going to be hit by meteorites. Since that meteorite just crashed in front of him, Chen Xin was not sure if the same opportunity would present itself again if he did not obtain a fragment of it as a souvenir then.


    The meteorite that hit the ground looked small. Except for a trail plowed out by the meteorite about several tens of meters in length, it left behind a crater that was about ten meters in diameter.


    The impact lifted all the soil near the landing point and pushed it aside. At the bottom of the pit, there was a slightly burnt trace, which seemed to still be steaming from the heat.


    Chen Xin climbed down, and the heat from the impact could still be felt at the bottom of the crater, but all he was concerned about was whether the meteorite could be found.


    To his surprise, Chen Xin saw something at the bottom of the crater, but it did not look like a meteorite.


    That was because meteorites could not be standard spheres anyway, nor could they emit light.


    What the hell was that? Chen Xin stopped in his tracks in fear.

 Chapter 22

    Chen Xin was a little undecided. He was worried that the object might be something weird, especially since it was still glowing. He started to associate the situation with bad outcomes given that The Colours Out of Space in the Cthulhu Mythos was also referring to a deadly virus that traveled on meteorites that eventually crashed into Earth. Those pathogenic organisms also emitted globules of colored light.


    However, Chen Xin¡¯s bunker was not far away. Even if it was The Colours Out of Space, it was too late for him to avoid its effects. Chen Xin gritted his teeth and approached the unknown object, then kicked it.


    The object at the bottom of the pit was not huge. It was about the size of a ping-pong ball, and there were some burn marks on its surface which peeled off when Chen Xin kicked it. It seemed like those marks were burnt residues of whatever substance the object was engulfed in as it traveled through the atmosphere.


    As the heat dissipated, the light emitted by the object gradually dimmed, and it became no different from any ordinary metal ball.


    When he saw that the object no longer shone, Chen Xin¡¯s gradually felt a sense of relief. It seemed that that was not The Colours Out of Space.


    He kicked it two more times. It did not seem to be dangerous, as there was no other reaction. Chen Xin hesitated for a while before picking it up.


    When he picked it up, the object was still a little hot. When he held it, the heat made the wound on his palm sting.


    Chen Xin did not care too much. He looked at the object and found that it resembled a small metal ball with a smooth surface. There was nothing special. It was still glowing before, but now it was just an ordinary metal ball.


    There was nothing more that he could tell from the object¡¯s appearance, so he put it into his pocket, and planned to return to the bunker so he could inspect it in detail.


    Chen Xin searched the crater and found nothing else that looked like a meteorite. He climbed out and walked toward the bunker.


    On his way, Chen Xin looked up at the sky and saw that those two meteorites had trailed below the horizon. He knew that the impact was going to be anytime soon.


    Although his location was far from the impact point, the effects of the blast would soon be felt.


    Chen Xin did not hesitate anymore and quickly returned to his bunker. After closing the heavy door, he picked up the TV on the ground and walked toward the depths of the bunker.


    Since Chen Xin¡¯s bunker had to be dug deep enough, the corridor leading down to the lower levels was about fifty meters long


    The corridor was built diagonally downwards. It was also fairly wide, considering that it had to provide access to construction equipment and for future vehicles entering and exiting.


    As he arrived at the inner bunker, Chen Xin put down the TV that he had been holding. Then, he sat down and looked around for the medical kit, intending to treat the scratch wounds on his palm.


    However, just as he found the medical kit and proceeded to wash his wound with water, he found that the wound had healed.


    If it were not for the bloodstains remaining on his palm, Chen Xin would have thought the injury was a hallucination.


    That strange occurrence immediately had Chen Xin thinking about the small metal ball he picked up from the crater, so he quickly took it out of his pocket.


    Chen Xin¡¯s pockets were a little tight. When he took it out, the ball fell to the ground.


    At the moment it hit the ground, a bright blue halo emerged where it touched the floor. In an instant, it scanned everything in the room, then retracted into the ball again.


    With the retraction of the halo, the ball lit up again and suspended itself in the air, parallel to Chen Xin¡¯s line of sight.


    Seeing what had just happened, Chen Xin still did not know that there was something wrong with the object he picked up. He stepped back with a bit of fear, picked up the medicine kit, and wanted to embolden himself.


    ¡°The Doomsday Survival System has been activated¡­¡±


    ¡°The target gene has been collected¡­¡±


    ¡°Confirming genetic makeup, carbon-based organisms¡­¡±


    ¡°Confirming living environment, the meteorite crisis, the possibility of biological extinction¡­ the conditions are met, the binding program commences¡­¡±


    The little ball made a mechanical beep. Much to his surprise, Chen Xin could understand what the little ball was saying, although the sound it made was in another language.


    As it continued beeping, the small ball flew in front of Chen Xin, projected a blue light that scanned his body, and then bolted toward Chen Xin.


    Chen Xin hurriedly blocked with the medical kit in his hand, but the small ball hit the back of his hand and then melted into it.


    Chen Xin was shocked. He threw down the medical kit and inspected the back of his hand, but found nothing unusual.


    Just when Chen Xin was feeling bouts of unease, his body underwent unexpected changes. A green halo that resembled a digital grid emanated from under his feet and scanned the entire bunker. It then retracted into his body, much like a radar echo.


    Chen Xin dumbfoundedly gaped at everything that was happening. His brain drew an utter blank. He had no idea what was going on, nor what kind of expression he should make.


    Chen Xin was puzzled for a long time. After he recollected his thoughts, he regained his senses and asked, ¡°What the hell is going on?¡±


    As Chen Xin raised that query, a large amount of information appeared in his mind and projected onto his retina in the form of words he knew. That quickly allowed him to figure out what was going on.


    To put it simply, Chen Xin had obtained an artificial system. It was akin to the leveling systems that were largely seen in tasteless and trashy fictional novels.


    That system was called the Doomsday Survival System. It was created by a certain advanced civilization in an unknown time and space, and it seemed to be one of their toys for entertainment.


    Even so, it did not matter how that system came about, what mattered was its functionalities.


    Since it was named the Doomsday Survival System, the function of the system would naturally be related to survival.


    According to the information displayed, as long as the host bound to the system manages to survive in the predetermined doomsday environment, he could obtain survival points for every day that he stayed alive.


    That was somewhat similar to accumulating experience points in other leveling systems. However, the Doomsday points could not be exchanged for just anything, it could only be used to upgrade items.


    Due to its intended nature as an entertainment product for some highly-advanced alien civilization, it was used to experience the fun of surviving a calamity. If one could trade for any item out of thin air, there would be room for cheating, and the overall experience of the survival game would be severely affected.


    Hence the function of that system was only to upgrade items, similar to the item synthesis upgrade function in many games, but in that case, the upgrade function was more robust and many times more powerful.

 Chapter 23

    Chen Xin was extremely excited about discovering the system.


    It was as if a mischievous child had suddenly got himself a novel toy. He could not keep his hands off it.


    In the bunker, to protect his electronics from the imminent EMP shockwave, he wrapped all of them in tin foil, then placed them in an iron box. Asides from playing around with his newly acquired system, there was nothing else that he could do.


    As Chen Xin tinkered around the system, he finally figured out how it worked, and what capabilities it had.


    The system itself was very crude. It was not so much a complete system, but more like an auxiliary program.


    There was no user interface for the program. There were only a few pieces of information that were displayed when Chen Xin engaged the system. Those were mainly his remaining survival points, projected in the corner of his retina; and the relevant upgrade information of the items that could be observed in Chen Xin¡¯s visual field.


    For example, when Chen Xin kept his gaze on a ballpoint pen he placed on the table, he could see two different upgrade options appearing on it.


    The first option was to add a bright flashlight function to the ballpoint pen, upgrading it to a pen-shaped LED flashlight similar to those commonly used by doctors in hospitals; the other was to add a glass-breaking function to make it a tactical survival tool.


    Chen Xin had often seen the first option in various medical dramas. It was an unassuming but hugely convenient pen that could turn into a bright flashlight with one click. Doctors would use it to inspect a patient¡¯s body at any time and anywhere. It was a very practical tool.


    As for the second option, in fact, as a survival enthusiast, Chen Xin had such a pen in his possession.


    It was made of titanium alloy. Its texture was hard and could be used as a tent nail or even a crowbar. It also adopted a bolt-type structure, which was much more reliable and easier to use than a button pen. The pen tip was designed to be a glass-breaker, which could be used to smash car windows in case of a car accident. It was pragmatically-designed and easy to use.


    Chen Xin also liked it very much. He used to keep it close to him. Whenever he got inspired, he would take it out and record his ideas.


    Of course, a titanium pen was not cheap. It cost Chen Xin more than 400 dollars.


    If it were not for the fairly decent compensation that Chen Xin¡¯s job as an online writer offered, he would probably not spend so lavishly on a pen.


    However, at that point, Chen Xin did not need to spend more than 400 dollars. He only required a two-dollar ballpoint pen, plus 5 survival points, and he could acquire the same titanium tactical pen.


    Although Chen Xin was eager to try out the item upgrade function, he did not do so due to having insufficient survival points. As such, he could only satisfy his curiosity by navigating through the upgrade options of various items provided by the system.


    The system¡¯s survival point round-up method was based on a 24-hour cycle. At every midnight, Chen Xin would acquire a day¡¯s worth of survival points, provided he stayed in the doomsday environment for 24 hours.


    Despite not having survived the first 24-hour cycle, Chen Xin was still rewarded survival points for the day as a novice benefit and introductory fund.


    That kind of benefit was only available when the system was activated. If Chen Xin escaped from the doomsday environment determined by the system, its functions would be temporarily frozen. The system would not be reactivated until he returned to the doomsday environment. At that point, Chen Xin would have to wait for another 24 hours before his survival points were rounded-up and rewarded.


    As for how Chen Xin could escape the current world that was fraught with catastrophes, it was a problem that the system¡¯s artificial intelligence was not equipped to solve.


    Due to having low survival points, Chen Xin did not bother to consider how many points it would cost to upgrade his items. Instead, he went through all the things in his bunker and wanted to see what the system could upgrade, and what were the options offered.


    Chen Xin knew he needed to plan for his future survival. He drew up a limited list of upgrades based on those available upgrade options so he would know which items to upgrade first.


    In the system, everything that appeared in Chen Xin¡¯s sight could be upgraded with survival points. Ordinary pens could be upgraded to tactical pens, ordinary scissors could be upgraded to emergency folding scissors, and flashlights could be upgraded to fully-functional tactical flashlights equipped with infrared and lasers¡­


    Even the self-heating food stocked by Chen Xin could be upgraded to visually appealing, high-end life-saving foods like those seen in science fiction.


    Chen Xin also discovered that the system could not conjure matter out of thin air. It could only transform existing matter into something else.


    Just like that plastic ballpoint pen that could be upgraded to a titanium tactical pen. The system could only change the material of the pen from plastic to titanium.


    Even so, that would only be realized on the premise of consuming survival points, so having survival points meant that one could acquire everything.


    The system upgrades were also not solely dependant on survival points. It also provided an option for material upgrades, which could reduce the consumption of survival points, but increase material consumption.


    In particular, if Chen Xin¡¯s ballpoint pen had 50g of titanium alloy, it would only need 1 survival point to complete the upgrade. If it was made of 200g of iron, 3 survival points would be required.


    As for other items, they basically adhered to similar upgrade rules. If Chen Xin could provide enough materials and ingredients, the survival points needed to upgrade his items would cost less. As for how much lesser, it would specifically depend on the materials that Chen Xin could provide.


    Chen Xin was very satisfied with the system¡¯s functions, which provided him with two options for survival.


    The first option was to be the power-leveling Swordmaster of Ten-Mile Hill. Chen Xin would hunker down in the bunker, accumulating survival points while upgrading his items and stay put until the bunker was solid and indestructible.


    The other way was to wait for the external environment to stabilize, and actively go out to collect materials, use them to upgrade the bunker, and ultimately make it impenetrable.


    Both upgrade methods were not necessarily better or worse than the other, but they represented two different development routes. Moreover, there was no one to stipulate that Chen Xin must choose one and give up the other.


    He could very well stay in the bunker for some time until it was upgraded to a certain level. After he was certain he had enough protection for his survival, he could go outside to collect materials and accelerate the upgrading process.


    On the one hand, it would take a certain amount of time for the external environment to stabilize. On the other hand, the external environment would become fraught with danger and uncertainty due to the doomsday natural disasters.


    After all, faced with the aftermath of a meteorite impact, most countries in the world would certainly fail to maintain a peaceful social order. The harmonious and pleasant living environment that humans were used to would cease to exist.

 Chapter 24

    The environmental effects of the meteorite impact would linger and devastate the Earth for the next dozens or even hundreds of years to come. Earth¡¯s surface would be devoid of sunlight and temperatures would drop to sub-zero. For animals and plants alike, it was impossible to survive in such an environment. Naturally, farming and food production were out of the question.


    In that situation where there was a shortage of supplies, many things such as cold-proof clothing, food to fill your stomach, fuel for heating, and bunkers to take refuge in would become very in demand. People would start becoming inured to murder, even if for a little bit of food.


    Even before the meteorite struck, millions of people were already dying every year because of hunger.


    In those war-torn countries that were ravaged by starvation, even human beings themselves could become dinner for others. Let alone the act of killing people for their food?


    If it were not for Master Druid Yuan¡¯s seminal discovery of hybrid rice, Vermillion would suffer from a food crisis just like other countries around the world.


    The food problem was a worldwide problem. As the world began to lose sunlight and became colder, it spelled the end of the global food production chain.


    When food production came to a halt, most countries in the world would plunge into a food crisis and their population would soon starve to death.


    This was because a considerable number of countries around the world had not solved their food security issues. They were usually dependent on imports, and no one could provide them with food once disaster struck.


    Under such circumstances, the more populous the place, the faster the consumption of reserve supplies. Any materials that may still exist in the outside world would become highly desirable.


    No one would say no to a surplus of supplies that guaranteed their survival.


    However¡­in a post-apocalypse world where morality, law, and order were lost, whoever had the biggest fist naturally stole the right to procure and hoard materials.


    In fact, to decide what to eat in the coming days was a problem for mankind. Without food from farmlands, human beings could not survive by relying on the reserves alone.


    The bunkers that the country had built should have a certain amount of materials in reserve, which would allow production to resume to an extent. After all, Chen Xin had a greenhouse farm in his bunker. He did not believe that the country was underequipped to accomplish that.


    Even so, a greenhouse farm could only provide a very scarce amount of vegetables and fruits. It was impractical to grow food in large-scale greenhouses at that time.


    At the very least, for the first few years of the natural disaster, it would be unrealistic to build a large-scale greenhouse farming system. It was also not cost-effective.


    It was important to know that although hybrid rice had a high yield, it was still a plant. Farming consumed a lot of water resources. Obtaining sufficient water resources was a huge problem in itself in the apocalyptic world, given the subzero temperatures.


    In truth, the state had no plans to construct large-scale greenhouses to grow food. According to the information released by the state to official government bunkers, the state would start growing mushrooms and raising rats to ensure future food security for the refugees.


    Compared with traditional crops that required sunlight and a lot of water, mushrooms were much easier to grow. As long as the culture could be kept in a humid environment and the darkroom could maintain a temperature of about 18-20 degrees, its growing conditions would be met.


    Although mushrooms were not as delicious as fruits and vegetables, edible fungi were rich in fat, protein, sugar, dietary fiber, and various vitamins, which could meet the nutritional needs of the human body.


    As for raising mice, it was a better way to obtain meat resources than raising other poultry and livestock. After all, mice were known to have high vitality, and it could be fed with minimal food resources.


    As long as the breeding environment was clean and hygienic, a stable meat source could be obtained.


    Nevertheless, even if those two plans could ensure a food supply, it would still be barely enough.


    After all, only the main bunkers in major cities were equipped with those facilities when they were built. Other bunkers in residential areas that were overhauled from underground air-raid shelters may not have had time to get those facilities installed.


    Even if there was, the projects would take a certain amount of time to fulfill the demand. In the early days of the doomsday era, most bunkers would still rely on stockpiled materials to survive.


    Unfortunately¡­ the material reserves were limited.


    As the calamity approached, the country had indeed built many bunkers, successfully migrated most people into them, and saved the lives of many in the first wave of disasters caused by the meteorite impacts.


    However, that also created another problem, that was, a higher population meant more material consumption.


    Survival would inevitably depend on the rate of consumption of food and water. In a shortage of supply, various social problems would arise as a result.


    The various disasters caused by the meteorite impact would destroy most of the communication facilities on the surface of Earth. The level of human communication was likely to regress to the era of telegraphs and wired telephones. Mobile phones and wireless communication would be rendered useless.


    When communication was poor, and everyone stayed in a closed and relatively independent environment, it was foreseeable that those communities would form their small circles. When the cat¡¯s away, the mice will play.


    Until the country regained control, the chaos could not be stopped. The dark side of human nature would be exposed as well.


    When would the country be able to resume production, construction, and rebuild social order? It was up in the air. Moreover, in the case of any extremities, the dangers of the outside world could rise exponentially.


    Just like the rescue team in ¡°The Wandering Earth¡±, they were equipped with exoskeletal armor and heavy firepower to perform rescue missions on the surface. Their firepower was not intended for petty reasons like breaking glass.


    In that situation, if Chen Xin did not have the means to protect himself and the bunker, he would certainly be unable to defend himself against foreign enemies. Then everything he had would become irresistible in the eyes of others.


    For Chen Xin, the 30 years before his life were peaceful years. He lived in the most secure country in the world, and he had never worried about his safety.


    Given that the doomsday era had arrived, that was a problem he had to worry about.


    Fortunately, playing survival games outdoors in the past had equipped Chen Xin with things that he could use to deal with possible dangers.


    A katana, a recurve bow, and two daggers. Those weapons would undoubtedly be confiscated by the police if wielded during peaceful times. Nonetheless, they gave Chen Xin a great sense of security in that doomsday era, as they could be used as a wilderness survival tool or self-defense tool.


    Especially since Chen Xin discovered that those weapons installed in the cabinet could be upgraded together with the cabinet as a whole, he felt even more confident.

 Chapter 25

    ¡°Simple Iron-Made Weapon Cabinet¡±


    ¡°Upgrade Plan A ¨C Upgrade cabinet material, increase cabinet volume, add maintenance and modification functions, existing weapon technology level +1, upgrade required survival points 500.¡±


    ¡°Upgrade Plan B ¨C Upgrade cabinet material, increase cabinet volume, add gun manufacturing module, obtain gun manufacturing blueprint +1, upgrade required survival points 450.¡±


    Looking at the upgrade plan of the weapon cabinet provided by the system, Chen Xin realized that the upgrade function was not as simple as he had expected.


    In other words, the upgrade function was much more powerful and advanced than he thought.


    Technology level +1, manufacturing blueprint +1, those were entries that did not appear when Chen Xin checked on other items.


    The other upgrades only showed what would be upgraded and the functions that would be acquired, there was no additional prompt stating things like XXXX +1.


    Chen Xin was astonished by that discovery. The entries of technology level + 1 and manufacturing blueprint + 1 meant that Chen Xin could make and modify his high-tech firearms!


    That made Chen Xin look forward to it. If he had continued upgrading, could he produce lightsabers and power armor¡­?


    Chen Xin fantasized about the scene where he would polish a Gundam mobile suit with his hands in the future, and passionate tears flowed from the corners of his mouth. Which boy on Earth did not like robots?


    Besides, the upgrade entry appeared on the cabinet as a whole, which meant that Chen Xin could pack things in a box or cabinet to upgrade them as a whole instead of one by one. That would completely change the game!


    For example, Chen Xin had his eyes locked on the room he was in at that moment.


    ¡°Container-type Modular House ¨C Bedroom Components¡±


    ¡°Upgrade Plan A ¨C Upgrade container material, improve insulation, improve temperature regulation and air circulation, life support level +1, required survival points to upgrade 3000¡±


    ¡°Upgrade Plan B ¨C Upgrade internal soft decoration materials, add smart home functions, living comfort level +1, overall technology level +1, required survival points to upgrade 4500¡±


    When he saw the whole room in his field of vision light up and the upgrade plan emerging, Chen Xin¡¯s mood became better. Being able to upgrade the bedroom also meant that he could upgrade the entire bunker.


    Just imagine, would it not be more efficient if he could get an upgrade of bunker technology +1?


    Furthermore, upgrading the bunker could also increase Chen Xin¡¯s survivability in the doomsday era.


    However, Chen Xin calmed down after he thought about those things. That was due to the survival points required for an upgrade.


    It only required five points to upgrade a pen and one point for a self-heating meal, but the toolbox required a hundred points, the generator for two hundred, and the weapon cabinet for five hundred. It would cost more than a thousand points for a single room. Those numbers quickly sobered up Chen Xin, who had zero points.


    Being able to upgrade an item or the bunker itself was wonderful, but the survival points could only be accumulated day by day and he did not know how many points he could obtain daily. In case he could only get one point a day, it would be impossible for him to save up enough to upgrade the entire bunker.


    The system itself did not provide any relevant data, but it did explain that when the host¡¯s survival conditions improved, there would be more points awarded daily.


    Therefore, being in a situation where only one point was obtained a day should not happen. Plus in Chen Xin¡¯s view, he should be able to obtain several points daily as he had his own bunker after all. Although the condition was not the best, it was still considered pretty good.


    Chen Xin put aside his worries as he thought about it that way. He picked up and tore open the first generation self-heating food that he took out to verify the system¡¯s ability, grabbed a bottle of mineral water, and prepared for dinner.


    The acquisition of the system brightened up Chen Xin¡¯s future, but it did not change the fact that it was doomsday and everyone was in a tough situation.


    Even though Chen Xin had hoarded a large number of supplies before the disaster, he limited himself to only having one pack of self-heating food which could last 2 meals, and a 1.5-liter bottle of mineral water a day to avoid wastage.


    Those were Chen Xin¡¯s conditions for survival after doomsday began.


    Even so, Chen Xin¡¯s living condition was considered as good as he had thought when compared to many people.


    At least Chen Xin had his private bunker which provided sufficient space for activities, adequate food reserves, and could generate electricity. He could even take out his electronic devices to play games and pass the time when the aftereffects of the EMP shockwaves had subsided.


    In comparison to the people who were now crowded into bunkers that were repurposed from underground garages or air-raid shelters, Chen Xin¡¯s living conditions were relatively exceptional.


    Chen Xin had also paid attention to when the government announced information about the official bunkers, the survival conditions there were not bad. However, the living conditions there were much worse than in Chen Xin¡¯s private bunker because so many people had to live together.


    To say nothing of other things, when hundreds of people were living in the same bunker, access to drinking water and toilets would be two of the most difficult issues to circumvent.


    After all, with the arrival of doomsday, a water supply would be the top issue faced by governments and many bunkers as the external temperature dropped.


    Although the government had carried out emergency renovations to those facilities before, guaranteeing a sufficient supply of drinking water under a subzero temperature environment was still a serious issue.


    As for the toilets, one could only imagine how bad a public toilet would look like when there were no janitors to clean them 24/7.


    There would be hundreds of people that needed to eat and defecate every day. If there were no prior planning and management, it would be disastrous.


    The country had taken precautionary measures in advance, but the period from the disaster warning to doomsday was too short. Even if Vermillion was an infrastructure powerhouse and had the best industrial infrastructures in the world, it had 1.3 billion citizens!


    In just three months, the preparations made by the country could only guarantee that most people would survive, but it was impossible to let everyone live comfortably at the same time.

 Chapter 26

    Previously, Chen Xin had read the information published by the government on the bunkers. Every family was allocated a room smaller than a university dorm.


    The rooms were only about ten square meters, even the beds provided were steel wired beds. It was not hard to imagine how tough the living conditions were.


    In Vermillion, it was normal for a family to live in a house about ten square meters back in the 70s and 80s, or even the 90s.


    However, half a century had passed since then and the standard of living conditions had considerably improved.


    Now that doomsday had arrived, the living conditions had to regress to the 70s, or even worse. That would no doubt be a huge test for mankind who had long been accustomed to the comfort of modern convenience.


    It was unimaginable for modern people to live without takeaways, the internet, soft drinks, and even meat.


    Other than that, they had to hide in underground bunkers and were not allowed to leave. To many people, that was no different from being thrown in jail.


    Even though the whole country managed to stay quarantined at home under the restrictions implemented by the government at the start of the year, many people succumbed to mental illnesses when the pandemic broke out.


    Chen Xin finished his meal while thinking about that. He threw the trash into the garbage bin after rinsing his mouth.


    Chen Xin had no intentions of throwing out his trash as the environment outside had not settled. He would definitely throw them out when the environment settles down.


    After dinner, Chen Xin had nothing to do, but he resisted the urge to play with his phone. Instead, he checked out his bunker for other things to do.


    However, there were not many things that he could occupy his time with.


    All the supplies were already neatly organized. Chen Xin had only moved in today, therefore there was nothing that needed to be arranged.


    Also, the bunker was not very big as it only contained a bedroom, a living room, a bathroom, and an electrical room. Those rooms were built with shipping containers and were Chen Xin¡¯s main activity spaces.


    Temperature-wise, the containers were much more comfortable than cement built rooms as they were filled with insulating materials.


    Besides that, the storage, water tanks, fuel tanks, sewage treatment tanks, generators, and the garage were placed in rooms dug out in the mountains outside the containers. After all, he only needed to ensure that the ambient temperature would not affect the functionality as they did not need to be insulated.


    If Chen Xin had lived in the bunker for a long time, he would need to check on all the equipment periodically for maintenance. However, only the generator was operating at that time, even the sewage treatment tanks were still clean.


    Chen Xin scratched his head, he could only inspect the generator¡¯s fuel tank again. Seeing that there was still enough fuel in it, he walked toward the electrical room.


    Chen Xin only had about 4000 liters of gas stocked up while his generator needed 20 liters per filling to generate over ten hours of electricity.


    However, Chen Xin did not need to let the generator empty its tank as his daily electricity consumption was not very high.


    Around six to eight hours of power generation was sufficient to fully charge the large batteries in the electrical room, which could supply enough electricity for the rest of the day.


    That day, the generator had already been in use for about four hours. It had not been for as long as he planned, but Chen Xin did not use much electricity other than for lighting purposes. Therefore, most of the electricity was used to charge the batteries.


    Chen Xin did not know if the batteries were full. If it was, he could then turn off the generator in advance and save some gas.


    In the electrical room, the indicator on the large batteries flickered as they charged. The fuse box next to it was also working normally.


    To be honest, Chen Xin did not plan to install a fuse box when the bunker was built. After all, it was only a small bunker with a small generator to light up the rooms. It would be a waste to install a fuse box.


    However, when he bought the container houses, the manufacturer included a fuse box with his order. So, Chen Xin just made use of it.


    Coincidentally, the fuse box, together with the electrical room and the generator could be regarded as one complete electrical system that could be upgraded simultaneously.


    Moreover, both upgrade options suggested by the System had fuel-saving and efficiency-improving entries.


    That was undoubtedly great news for Chen Xin. The post-upgrade increase in power generation and reduction in fuel consumption were both important to him because it would make his fuel reserves last longer than expected.


    After doomsday, gasoline would surely become an important commodity and it would not be as easy to obtain as before. Therefore, if one could save even just a little, there was no reason not to.


    Chen Xin checked on the large batteries¡¯ indicators. They did not show that they were fully charged yet, so Chen Xin was not in a rush to turn off the generators.


    He estimated another hour¡¯s time until the two batteries would be fully charged. Chen Xin then looked at his watch and took note of the time, and went back to his bedroom.


    Nevertheless, Chen Xin still had nothing to do when he returned to his bedroom. He had no choice but to lie on his bed and daydream.


    If it was in the past, he would have taken out his mobile phone to play games and watch videos, but now the mobile phone was wrapped in thick layers of tin foil and stuffed in an iron box. He would need to wait for a few days for the aftereffects of the EMP shockwaves to subside before it could be used.


    Chen Xin could not use any electronics for a few days.


    As he thought of the EMP shockwaves, Chen Xin could not help but wonder about what the outside world was like currently.


    Chen Xin had already entered the bunker for more than half of the day. Throughout that period, the shockwave generated by the meteorite impact had swept across the Earth. Even if he hid underground, he still heard the violent blasts. It made him think that something in the bunker might have broken, or maybe the meteorite crashed at the entrance.


    Since the meteorite had fallen, the vicinity of the impact site had become hell. The heat released by the impact would eventually set the whole Earth on fire.


    Thinking of that, Chen Xin could not help but sigh.


    That was not a wildfire, nor the extinction of a species. It would be a raging flame that would sweep through the world, destroying the entire ecosystem.


    More than ninety percent of land creatures on Earth would not escape that conflagration.

 Chapter 27

    ¡°Cough!¡± Chen Xin choked and woke up.


    It was Chen Xin¡¯s third day in the bunker. After two days of adjustment, Chen Xin felt like he had already adapted to life here.


    It was just that the whole bunker was filled with smog which choked and woke him up.


    Chen Xin got out of the bed and switched on the lights as he coughed and covered his mouth.


    He tremblingly put on his clothes, but still felt dizzy. Even his breathing was ragged.


    Chen Xin knew that it was not because he was only half awake. It was because he inhaled the harmful gases in the smog which made breathing difficult.


    If he did not wake up and continued to sleep, he would most likely be dead due to anoxia or severe intoxication.


    Chen Xin came to his senses and hurriedly found the gas mask and oxygen tank from the cupboard. After he took a few breaths of oxygen, he put on the gas mask.


    At that moment, Chen Xin finally felt at ease. Only then did he have time to think about what happened.


    There should be no fire outbreak because he had not started any fires earlier. He had only used an induction cooker for boiling water.


    However, Chen Xin did not think too much. He ran to the garage, picked up the fire extinguisher from the trunk, and started to inspect every inch of the bunker.


    What made it stranger was there were no fire outbreaks, nor were there any smoking points.


    Where did the choking smog come from? Obviously, those gases were the result of something being burnt! Chen Xin did not believe that there was no fire at all!


    When Chen Xin circled back, he finally found out that the smoke was coming in from the ventilator.


    That discovery made Chen Xin realize that the outside was on fire!


    It had just been two days, did the fire caused by the impact finally reach here?


    That also made Chen Xin feel helpless. Even if he knew the cause, he could not solve the problem.


    That was a fire that spread through the entire world and most plants would be set ablaze. Although Chen Xin had not gone out, he believed that the mountain above the bunker had caught on fire. Otherwise, there would not be so much smoke in the bunker.


    Not to mention the ventilation system was specifically designed to filter smoke and harmful gases under normal circumstances.


    Nevertheless, given the current situation¡­ The concentration of the smog had already exceeded the ventilation¡¯s limit.


    Chen Xin felt helpless and hopeless at that time. Would he suffocate to death?


    Although he prepared gas masks and oxygen tanks, those items had a functional time limit.


    In an environment where the smoke gradually got denser, the gas masks could only last a few hours before the filter had to be changed, even if the quality was good enough. The oxygen tank could only last him for about two hours.


    According to Chen Xin¡¯s estimation, the fire in the mountains would not last very long as it would be extinguished due to the drop in temperature as a result of the sky being obscured by dust clouds. Even so, it would still last for several days or more than a week.


    Originally, Chen Xin thought that his bunker¡¯s ventilation was sufficient, but reality had given him a merciless slap.


    The ventilation that Chen Xin was so confident of obviously could not withstand the fire outbreak in the mountains. If Chen Xin could not figure out a solution, he would suffocate to death when his gas masks and oxygen tanks ran out.


    Escape? That idea was obviously impossible.


    The smoke had already gotten into the bunker, it was conceivable that the outside was surrounded by flames. Even if Chen Xin opened the door and ran out, he would only turn from smoked bacon into a roast duck.


    Even if he could make it out, where could he possibly go?


    The fire was not only at his mountain but had spread throughout the entire world.


    At that moment, ninety percent of the plants on earth had been set ablaze by the heat released from the impact. Every surface on earth caught on fire and there were no places to escape to.


    There may be no flames on the sea, but how was Chen Xin supposed to travel from inland to the coast?


    All transportation systems had been shut down due to the meteorite impact. There may be secret routes in the country, but why would it be opened up to an ordinary person like Chen Xin?


    Plus, if he could use the secret routes, why would he still need to run? He could have just stayed in the country¡¯s secret bunkers.


    As for the official bunkers, those were indeed an option.


    The main problem here was, how should Chen Xin convince the officials to open up the door under the blazing heat?


    As a matter of fact, Chen Xin had built a twelve-centimeter thick explosion-proof metal door. Even if you hit the doors with sledgehammers from the outside, the people inside might still not be able to hear you let alone knocking with bare hands. Plus, Chen Xin even installed double layers for safety reasons.


    One could only imagine how the gates of the official bunkers would be like.


    That was why Chen Xin had never considered escaping from the beginning.


    However, if he did not escape, what should he do to survive?


    The ventilation system had already reached its limit. Unless he could upgrade his ventilation, otherwise he would end up suffocating to death in the bunker he built for himself!


    Hold on! Chen Xin roused and realized he had neglected something important!


    He could actually upgrade the ventilation because he had The System!


    When he thought that, Chen Xin immediately opened up the user interface and directed his sight onto the ventilation duct.


    As expected, the ventilation duct in his view lit up, and an upgrade plan appeared.


    ¡°Natural ventilation system¡±


    ¡°Upgrade plan 1: Upgrade filter material, improve air filtration level, increase forced mechanical ventilation function, upgrade required survival point 100¡±


    ¡°Upgrade plan 2: Upgrade pipe material, increase insulation level, increase temperature adjustment function, upgrade required survival point 100¡±


    Chen Xin chose the first upgrade plan without hesitation.


    As he confirmed, the grid-like light appeared again as it did when the system was booted for the first time. The light only covered the ventilation duct at that time.


    Soon, the brightness dissipated, and the ventilation ducts had been renewed. The upgrade had been completed.

 Chapter 28

    However, even as the upgrade was completed, the bunker was still filled with smog and harmful gases. Chen Xin immediately wanted to engage the forced ventilation function to circulate the air.


    He found the switch for the function, but nothing happened even after he pressed it twice.


    Chen Xin was taken aback and hurriedly examined its surroundings. Only then he realized that the function required electricity.


    Fortunately, the ventilation circuit had already been connected to the switchroom. He only needed to turn on the circuit to engage the forced ventilation function.


    After messing around for a while, Chen Xin finally felt relieved when he heard the sounds from the duct brought by the spinning fan and the high-speed airflow.


    However, the batteries had limited electricity after all. Chen Xin then filled the generator with fuel and started it up as he was worried the electricity might be insufficient. Then, he collapsed onto the sofa in the living room.


    After forcing the ventilation for about half an hour, Chen Xin thought that it was enough. He took off the gas mask, sniffed the air, then disengaged the function when he felt like he could not smell the smog anymore.


    Although the function saved Chen Xin¡¯s life at that time, it did not need to be turned on all the time. Not only was it very noisy when turned on, but it also consumed a lot of electricity.


    If it was not necessary, it would be better to leave it turned off and save on resources.


    After he did so, Chen Xin returned to the sofa. Only then did he let go of the anxiety and panic caused by the incident. He started to think about what happened.


    That incident was alarming for him as his seemingly safe bunker still had loopholes. If it was not for the upgrade system, he might have already suffocated.


    If he did not wake up on time, he would probably be smothered to death in his sleep.


    Therefore, if Chen Xin wanted to survive, he had to increase his alertness. Simultaneously, he had to make good use of the system and upgrade the bunker as much as possible to better protect his life.


    Through that incident, Chen Xin had also determined that if it was not necessary, all the survival points would be invested in upgrading the bunker instead of other disposable items. Other than that, he would need to save up points in case of an emergency.


    If it was not for Chen Xin having just enough survival points, even if the system could be upgraded, he would have insufficient points to do so. In the end, he may still have suffocated to death due to an overdose of harmful gases.


    Chen Xin obtained ten points a day at that time. The reason why he managed to save up the required hundred points to upgrade the ventilation system was that he gained an achievement when The System first rounded-up his survival points.


    ¡°Rewarded with one hundred survival points for owning a bunker.¡±


    Through that, Chen Xin also learned that an alternative way to obtain survival points for The System was through achievements.


    However, he was still miserable about what kind of achievements were there. He did not research it very thoroughly. Therefore, he was still depending on the ten points awarded daily.


    Of course, as the bunker was upgraded, Chen Xin¡¯s living conditions would improve, and the daily rewarded points would also increase accordingly.


    Therefore, Chen Xin was very confident about his future. Even if the world came to an end, he would be able to live in better conditions with the help of The System as long as he worked hard.


    With that belief, Chen Xin cheered up again.


    Although he was choked by the harmful gases, his mind became sober as the effect of the gases gradually subsided with the oxygen tanks providing him oxygen.


    When he recovered, Chen Xin thought about it seriously. The System¡¯s condition for increasing the daily rewarded points was to improve his living conditions. Then, what were the things in the bunker that could be done to improve that?


    Chen Xin took out his portable notebook in which he recorded some of his findings in the past two days.


    He flipped through the records and looked at the contents he had listed down. After thinking about it, he took out a pen, turned to a new page, and drew a new table on it. The first line he had written down was medical treatment.


    That incident reminded Chen Xin that the first criteria of survival were to ensure that he could stay alive. Therefore, a complete medical infrastructure would exponentially increase his chance of survival.


    In an environment where there was a lack of doctors and medicines, Chen Xin could not leave for a doctor¡¯s visit no matter how ill he was. On top of that, he only had some common medicines in storage. It would still be okay if he had caught the flu or fever, but what if it was an uncommon disease? If that happened, he might as well just shut his eyes and wait to die or stab himself with a knife.


    Hence, a complete set of medical facilities was exactly what Chen Xin needed the most. It would be best if there could be a medic room, or even better if there was a medical bay that could treat someone who had their brains blown off like in science-fictional movies.


    Fortunately, The System existed. Chen Xin believed that it was not difficult to accomplish that. It was only a matter of accumulating sufficient survival points.


    After careful consideration, Chen Xin added food before medical treatment.


    Eating was an inelastic demand for everyone every day. Nobody would dare to say that they did not need food.


    It was the same for Chen Xin, he also needed to eat.


    Although he had stored enough food in the bunker, it would eventually run out. That was why he built a greenhouse and got it sorted out in the first two days. He had even sown the first batch of seeds.


    ¡®Maybe I should upgrade the greenhouse next?¡¯


    Chen Xin listed the greenhouse as a priority to be upgraded, but not as his first choice.


    That was because he had to consider how to maintain the greenhouse¡¯s operations before upgrading it.


    Chen Xin used supplementary lighting to provide artificial sunlight to the plants, but those supplementary lights consumed a high amount of power. If he wanted to upgrade the greenhouse, he would first need to consider upgrading the electrical system to ensure there would be sufficient energy.


    As he thought of the greenhouse, Chen Xin decided to pay a visit there. He did not know if the seeds he planted before had sprouted.


    Chen Xin was very concerned about it. After all, it would directly affect if he could eat fresh vegetables, and if he could still eat after his reserves had been depleted.

 Chapter 29

    The greenhouse farm in Chen Xin¡¯s bunker was not big. It was only one hundred square meters, which was one hectare, or one-sixth of an acre.


    Chen Xin had made a mistake there. When building the greenhouse, the construction team asked him how big he wanted to build it. He mistook hectare for acres. In consequence, the area of the greenhouse was six times smaller than planned.


    In Chen Xin¡¯s original plan, it would be used to grow upland rice and vegetables. That would provide him enough food to guarantee his normal consumption and to exchange for resources.


    However, the output was far from enough as he had made a mistake in his calculations.


    The yield per acre of upland rice was about nine hundred pounds, and it would drop to about seven hundred after the rice was dehusked. One hectare was equivalent to only about one-sixth of an acre, so the projected yield would be just over one hundred pounds then.


    The total amount of rice that an adult needed to eat in a year was about three hundred pounds. In addition to that, they would need to eat the same amount of meat and vegetables. In other words, if Chen Xin wanted to maintain a healthy body, he must eat at least five to six hundred pounds of food a year.


    As food was the main provider of energy to humans, perhaps his food consumption would only increase because the surface temperatures would drop to sub-zero.


    In that predicament, Chen Xin had already given up on meat. However, even if he could harvest rice twice a year, his yield would be around three hundred pounds at best. Despite that, he still would not have sufficient space to plant vegetables.


    Three hundred pounds of rice could never meet Chen Xin¡¯s needs for a year.


    Chen Xin had intended to plant half an acre of upland rice for himself, to begin with. The other half would be used to plant carrots, cabbages, lettuces, and other vegetables.


    Other than providing enough vegetables for himself, he would also trade for resources with other bunkers using the surpluses.


    After all, doomsday had arrived. There was no sunlight on the surface and temperatures had dropped drastically. The farming of crops and vegetables could only depend on those greenhouses.


    Having a greenhouse that could grow food and vegetables was a guarantee toward one¡¯s living quality and food supply. At least Chen Xin could still rely on the greenhouse to survive when there were no other food sources available.


    In addition to that, if Chen Xin had found a reliable way to produce food and vegetables in the apocalyptic era, it would turn into a very reliable source of income in the future.


    At that time, exchanging fresh vegetables for other kinds of food and supplies, or even fuel would be a very feasible option.


    That was just like the underground city in ¡°Wandering Earth¡±. The food that everyone ate was made of earthworms. If you had suddenly brought out fresh fruits and vegetables, it could be exchanged for some rare items.


    It was just that because of his calculation error, his output had shrunk to one-sixth of the original. It was not even enough to meet his consumption, how would it provide him with surpluses for trading?


    If he wanted to meet his consumption for the year, the size of the greenhouse had to be at least doubled. If he wanted to produce extra to exchange resources, the size had to be at least three to four times larger.


    From the get-go, Chen Xin could not expand the greenhouse. Although the greenhouse was not like the container houses, he had the construction team insulate its walls. He even poured cement into it. If he wanted to expand it, at least one side of the wall had to be knocked down, and he would need to slowly dig at the walls with a shovel.


    It was true that there was nothing to do in the bunker, but to dig a hundred square meters greenhouse would take Chen Xin at least two months.


    As for insulating the walls after that, he could forget about them. He did not have the right materials.


    However, it was different for him at that time since he had The System.


    ¡°Basic Greenhouse Farm¡±


    ¡°Upgrade Plan A ¨C Add drip irrigation system, increase the number of hydroponic grow trays, crop yield +10%, irrigation water consumption -10%, upgrade required survival points 2000¡±


    ¡°Upgrading Plan B ¨C Increase planting area, improve lighting efficiency of supplementary light, crop yield +10%, lighting time -10%, upgrade required survival points 3500¡±


    The two upgrade plans were different, but both increased the farming surface area of the greenhouse.


    The hydroponic grow trays in the first plan would be set in the air. It would turn the hundred square meters greenhouse into a two-layer system, with the lower layer being used for upland rice and the upper layer for vegetables and fruits. Plus, the upgrade would increase the crop¡¯s yield by ten percent, which would be sufficient to meet Chen Xin¡¯s needs.


    As for the second plan, it was the same as what Chen Xin had planned at first. One side of the wall would be knocked down to expand the greenhouse to two hundred square meters. That could also meet Chen Xin¡¯s consumption needs, but compared to the first plan, the utilization of space was much lower.


    Moreover, the first option also added a drip irrigation system. That was the most effecient method and could reduce the usage of up to ninety-five percent of his water resources. It was originally used for irrigation in areas where drought was common. As for Chen Xin who would face difficulty in obtaining water resources in the future, that would save him a lot of water which would otherwise be wasted.


    However, Chen Xin was also interested in the improvement in the efficiency of supplementary lighting in the second upgrade plan.


    Supplementary lights were used to simulate artificial sunlight. Most greenhouses needed that equipment to increase photosynthesis for the plants.


    That was because most of the time, the lighting condition was not ideal. That would affect the growth of the plants, especially for expensive and delicate breeds. The supplementary lighting was necessary as plants in different stages of growth had different daily lighting requirements.


    Chen Xin had four lights installed at the greenhouse. With the lights turned on for twelve hours a day, it could completely replace natural lighting and reduce lighting time for an hour, saving quite a bit of electricity.


    The area was still small and the energy-saving effect was minimal, but if the area expanded and the number of lights increased, the effect would be more obvious.


    However, Chen Xin was only accumulating ten points a day. He had not saved up enough survival points to spend for the upgrade, which required two to three thousand points.


    Therefore, Chen Xin could only devise a plan according to the upgrade fees and importance of different rooms. As to upgrading the rooms for real, Chen Xin estimated it would take about one year.


    Of course, if Chen Xin had chosen to upgrade a certain piece of equipment or item instead of the whole room, it would only take him a few months to save enough points.


    However, when he considered the price-performance ratio, Chen Xin still did not want to go through the hassle of upgrading item by item.

 Chapter 30

    Perhaps it was because he naturally had a slight obsessive-compulsive disorder, Chen Xin preferred collecting things in sets. It was just like video games where you would equip a complete set of equipment instead of some spare armor. Therefore, he preferred upgrading the room as a whole instead of by parts.


    Of course, that was also to reduce the hassle when it came to improving the set. After all, he could just upgrade the whole set instead of wasting effort in manually adjusting the coordination between parts.


    If it was someone who knew the ropes, they would certainly be able to integrate different parts together as they would know what parts work best with each other, maximizing their performance.


    However, what about the people who did not know? It was a given they would not be able to do that. How would they be able to integrate a full set if they did not even know what each part did?


    Sometimes, a complete set may not be optimal, but at least it could still prove useful.


    Chen Xin worked hard researching doomsday survival and learned a little bit in every aspect, but he was not a survival guru who knew everything.


    For example, would there be a conflict between the hydroponic growth trays and the drip irrigation system? Could the drip system be used for the hydroponic growth trays? How should he use the supplementary lights to ensure adequate lighting between different crops?


    Chen Xin could not answer these questions. Even the configuration of his greenhouse was done according to someone from the survival group chat who had hydroponic cultivation experience. If he had to do it himself, he would have plowed the field, sowed the seeds, and watered them the old fashioned way.


    No one could be a know-it-all. If Chen Xin was a survival guru, he would know what suited his needs the best, which functions should be upgraded, and how to maximize his survival probability.


    However, Chen Xin was just an ordinary outdoor survival enthusiast, and his professional knowledge was limited. It was already very good that he was able to judge what needed to be upgraded based on the plans offered by the system.


    If it were someone else, they would probably panic as they wanted everything.


    Of course, Chen Xin wanted everything too, but that required capital. How was he going to accumulate sufficient survival points for all the upgrades?


    Moreover, the system was a bit strange. It would only offer two choices when upgrading. If you wanted to use survival points, you could only choose from one of the two plans.


    If you wanted the upgrade to include features from both plans, you would need to provide all the materials required.


    Therefore, Chen Xin could only think about how he should spend the points while he saved up daily.


    At that time, he could not get out and gather any resources. That meant he could only rely on the survival points to upgrade anything.


    At the rate of ten points a day, he could earn up to three thousand and six hundred points a year. That was enough to upgrade an entire room, but Chen Xin thought if that was the case, then the system was quite useless.


    Hence, Chen Xin considered upgrading some key equipment to improve his living conditions and increase the daily awarded points.


    It was just that Chen Xin was still anxious about what he should upgrade.


    It was not that he could not find anything to upgrade, nor did he panic because he did not have survival points, but there were too many choices. It was very difficult to determine what should be upgraded to improve the system¡¯s assessment of his living conditions and increase his daily points.


    Fortunately, there were not enough points for Chen Xin to upgrade anything yet. Plus, there was nothing much to do in the bunker, so he had a lot of time to think about it.


    At that moment, Chen Xin was also concerned about the seeds sowed in the soil of the hundred square meters greenhouse.


    There were three kinds of seeds that he planted, namely carrots, cabbages, and lettuce.


    The cabbage seeds had already sprouted as Chen Xin processed them in advance. The carrots and lettuces would take a few more days to grow.


    In Chen Xin¡¯s original plan, the seeds of the upland rice should have been sown together with the vegetable seeds, but he could only plant the vegetables first because he had made a mistake during the greenhouse¡¯s construction. At least he was able to ensure vegetable supplies.


    Among those vegetables, lettuce grew the fastest. Under optimum temperature and humidity, it could be harvested once a month.


    The growth cycle of cabbage was similar to that of lettuce, and it could also be harvested in about thirty days when growing conditions were optimal.


    As for the carrots, it would be slower. Even if the temperature were suitable and the irrigation guaranteed, it would take three months to harvest. Carrots had the longest harvest cycle amongst the three.


    However, compared to cabbages and lettuces which had a shorter shelf life, carrots could be stored for a longer time.


    The reason Chen Xin planted vegetables first was also that they could be harvested in one month and the output could be obtained as soon as possible.


    As for upland rice, even if it could be harvested twice a year, a six-month growth cycle was still fairly long for Chen Xin at that time.


    Were it not for the system, Chen Xin would choose to grow the upland rice first. It could guarantee a steady food supply before his reserves were depleted. After sufficient food was harvested, he would plant some vegetables. While adjusting his palette, he could also bring some produce to the outside and trade with other bunkers.


    However, things had changed for Chen Xin since he had acquired the system. If he had planted vegetables first, not only could he eat better and improve his living conditions, he could also save some of his reserves.


    As Chen Xin had accumulated enough survival points, he could expand the greenhouse. He could still plant the upland rice by that time and it would not cause a food shortage. After all, he could still trade the vegetables for other kinds of food.


    In truth, vegetables were very rare for people who had been eating mushrooms and mice. Chen Xin was not worried that he could not make a decent trade.


    After he inspected the moisture level of the soil and turned on the supplementary lights, Chen Xin left the greenhouse.


    Greenhouse farming had one advantage over outdoor farming, that was he did not need to worry about pests and diseases. He would only need to ensure irrigation, lighting, and maintain the environment at an optimum temperature to guarantee a harvest.


    The crops had not grown yet, so there was nothing much that Chen Xin could do. He just had to check whether they needed to be watered.


    Upon closing the greenhouse door, Chen Xin walked toward the storage. He took a pack of self-heating food and a bottle of mineral water, then returned to the living room to prepare for dinner.


    Food was limited and energy consumption was not high. Chen Xin only ate two meals a day. Although it was not quite enough, it could still fill his stomach.


    While the food was heating up, Chen Xin suddenly thought whether he should build himself a kitchen. That should be regarded as an improvement to his living conditions, right?

 Chapter 31

    Chen Xin did not know whether building a kitchen would improve his living conditions, but he could tell his survival points went up ever since he started upgrading certain things.


    Once he upgraded his ventilation system, his survival points went from ten points to eleven.


    An improved ventilation system only helped with one survival point, Chen Xin felt like it was not enough. However, it was still good news.


    Chen Xin was confident in renovating his cooking area so he planned to build a kitchen and gain more survival points.


    Even though Chen Xin was ahead of schedule, he still tried to clear an area for his induction stove, pots, pans, and his tableware. However, he could not do much without survival points.


    Thankfully, the system provided previews, Chen Xin knew it was possible to have a kitchen. He did not have a real kitchen yet, just a bunch of stuff in a cooking area.


    ¡°Basic Simple Kitchen¡±


    ¡°Upgrade Plan A ¡ª Integrate an induction stove, a sink, and a wall cabinet. Two hundred survival points were required for this upgrade.¡±


    ¡°Upgrade Plan B ¡ª Integrate a multipurpose stove, a sink, and a freestanding dishwasher. Three hundred and fifty survival points were required for this upgrade.¡±


    Chen Xin felt relieved and excited seeing that the system recognized his abundance of stuff as a kitchen.


    He was excited because the system could do more than upgrade the existing rooms. By using the same method he used to renovate the kitchen, he could group a bunch of items together and create useful areas like a medic room or a gym. As for his unboxed electronic devices, he might be able to build a gaming area or an entertainment room from them.


    He should try upgrading the entire bunker to see whether he could create new rooms. It was more effective than trying to upgrade his existing rooms.


    The kitchen upgrade plan did not require a lot of survival points so Chen Xin decided to prioritize the kitchen if there were no other important room options to build.


    The medic room was at the top of his list too. He grouped his medical items together but unfortunately, the system did not consider it as a medic room. It recognized it as medical items and provided upgrade options for a first-aid kit or a medicine equipment package.


    Chen Xin was disappointed that he could not build a medic room.


    He expected this since he only had a few medical items. He only had an outdoor first-aid kit and a family-friendly medicine kit. His outdoor first-aid kit was basic. It was useful for minor injuries but it was far from a battlefield first-aid kit, he could not perform a surgical first aid.


    Chen Xin needed to wait until it was okay to go outside and collect more equipment to be able to build a medic room.


    He could also use all his survival points on his medical items like constantly upgrading his first-aid kits. He might end up being able to create a medic room just from upgrades.


    However, it was unrealistic. His medic room would end up being too costly, and he could not afford to waste his survival points.


    Chen Xin considered it but gave up on the idea.


    He could not go outside yet because it was not safe, Chen Xin decided that the medic room could wait.


    The medic room was not a priority even if he could go outside. Chen Xin felt like he should gather and collect items before considering a medic room.


    He decided his next step was to focus on upgrading the kitchen. He placed the medicine kits back in the cabinet of the living room.


    Chen Xin noticed a big metal case underneath the cabinet, it was the metal case he used to contain his electrical equipment.


    He used it to prevent the EMP shockwave from the meteor crash. Chen Xin wrapped his electrical equipment in aluminum foil and placed it in this metal case before moving into the bunker.


    This was the only way he could think of to preserve his electrical equipment.


    It was boring in the bunker, even with the help of the system. He would just tend to the plants, worry about upgrades, and tidy his items. He would mostly worry about the situation outside. Basically, he did not have much to do.


    If Chen Xin did not have the system, he might feel like it was the end of his world.


    All he did was to prepare his bunker, he was alienated from the outside world. It was hard to get information and he did not know whether he would survive, so he worried about his future and the future of humanity.


    Chen Xin did not want to go outside eventually and find out that Earth was destroyed. It would be even worse if he was the only survivor left in the world.


    Chen Xin felt like it would be easier to kill himself if that was the situation.


    He could not imagine living and dying alone as the last human.


    Chen Xin did not have to courage to survive like Will Smith in the movie ¡°I Am Legend¡±, he could not face the danger and loneliness by himself.


    Chen Xin wanted to take out his electronics from the case. He could pass the time by playing some video games on his phone or laptop, but most importantly, he could contact the outside world with his shortwave radio.


    He promised to stay in contact with his friends in the survival group chat, before moving into the bunker. They previously agreed on setting a radio channel to send messages and contact each other on.


    However, Chen Xin eventually resisted his urge and did not open the case.


    The EMP shockwave might not have passed yet, also he could not access the radio anyway.


    Chen Xin was a bunker two hundred meters underneath the ground. He was alienated from the outside world and there was no reception that deep.

 Chapter 32

    Chen Xin had to install the antenna outside to receive radio waves and to contact the outside world.


    He had to wait until the fire outside was extinguished to do that. Chen Xin could only walk out of the bunker when the temperature had cooled down, which according to his calculations, would take at least a month.


    However, the EMP shockwave would pass in just a few days.


    EMP stood for electromagnetic pulse, it was a sudden high-intensity pulse of electromagnetic radiation that usually lasted a second.


    Electromagnetic pulses were usually caused by explosions, lightning, sunspots, electrical conduits, or sparks from electrical equipment. An old TV model would be broken when struck by lightning because of the electromagnetic pulse caused by the lightning which would burn and destroy the TV parts.


    It does not last for long under normal circumstances, but an electromagnetic pulse from a meteorite strike would last a bit longer than usual.


    Chen Xin waited for days because aside from the big meteorite, there were smaller meteorite bits and debris that kept falling from space.


    The meteorite debris and other space matter kept crashing on Earth these days, the ionosphere was constantly disturbed and creating electromagnetic pulses.


    The safer method to protect his electronic devices was to wait for a few days.


    He would not wait forever for the small debris strikes to be cleared, because it might take a few hundred years for that. The disturbance in the ionosphere would be constant but it would not have a huge impact anymore.


    The big meteorite crash affected the ionosphere globally, the small space matters were less effective in comparison. It would not last long and quite frankly irrelevant.


    Chen Xin was waiting for the bigger debris to strike, it would last around a week according to his calculations. He would wait for a week before unboxing his electronics.


    The EMP shockwave from the small debris strikes was not powerful enough to penetrate underground, his electrical items would not be affected.


    He could tell because his lightbulbs had been flickering all day at first, some of the lightbulbs were already burnt, but now they would only flicker once every few hours.


    Chen Xin only had to endure it for a few more days but he was extremely bored, he wanted to play video games on his devices.


    His underground bunker was not as deep as the others, but the thick soil above it was sufficient to avoid all kinds of disasters. It had also alienated him, he could not hear anything that was going on outside.


    Chen Xin was used to being alone because of his work as an author. Truthfully, were it not for his career, he would feel like a military prisoner placed in solitary confinement.


    It was way too quiet here. He depended heavily on the lights too. Chen Xin would not be able to tell between day and night if he switched off the lights.


    He referred to a mechanical pocket watch and the daily round-up for the time, or else he would be confused on what time it was. He had no idea what day it was or whether it was bright or dark outside.


    The sky outside must be covered with dust because of the meteorite crash. They might not see the sun again making it hard to tell the difference between daytime and nighttime.


    Chen Xin knocked on his forehead. He suddenly felt like he should have bought a smart window. Not the type that would automatically adjust the lighting and UV rays, but instead a smart window that could artificially display outdoor scenery.


    He could change the scenery according to the time, it was a must-have cheerful item for someone like Chen Xin.


    The Earth had been destroyed by the wildfires, followed by long nights and the freezing winter solstice, it was obvious that beautiful landscapes did not exist anymore. He wished he had the smart window as a reminder of what Earth once was.


    However, it was wishful thinking, he did not think of getting a smart window so he could only gaze at the cold ceiling.


    He could not create a smart window with the system. Maybe he might be able to once he upgraded his room, there might be new items following the upgrades. Chen Xin felt like he should prioritize the lighting system.


    A lighting system upgrade feature was that it could automatically adjust the brightness and tone according to the time. It was way better than the same stoic bunker light from the fluorescent tube.


    He could schedule his time better if he felt the transition in time, he also did not have to live so gloomily anymore.


    Chen Xin took out his notebook, flipped to the page that had ¡®food¡¯ and ¡®medic¡¯ on it. He wrote ¡®lights¡¯ on that page.


    However, if he upgraded the lights, would his electric usage increase?


    He stopped writing and thought about it. He inserted ¡®power source¡¯ in front of ¡®lights¡¯.


    The electric usage in the bunker was not a lot. Plus, his generator was not running at full load either so most of the generated electricity was stored in the battery, but if he upgraded his equipment he might have an increase in electric usage. He had to put upgrading his generator into consideration.


    A generator upgrade meant burning more fuel, how long could he last with his three tons of gasoline?


    Chen Xin carefully thought about it and realized it was not a big deal. He could wait until it was alright to go outside, trade his vegetables for other resources as he originally planned. Or he could simply upgrade his fuel generator into a black technology device. Both ways could solve his problem.

 Chapter 33

    Chen Xin finally waited until the lightbulbs stopped flickering after a week in the bunker. He opened the big metal case at the speed of light. He hurriedly tore off the aluminum foil as he took out his phone, laptop, and gaming console.


    Chen Xin felt a sense of joy and happiness brought by technology.


    A phone was already an indispensable accessory for the modern-day human being. Smartphones had a lot of functions even without an internet connection and signal.


    The simple apps on a smartphone had a lot of different functions. If you observe closely, these apps already seeped their way into our daily lives in various aspects.


    For example, Chen Xin used to scroll on his phone for half an hour when he woke up, and before he went to sleep. He was not trying to scroll for something important or to chat with someone, it was just an unfixable habit. He needed to check every app he had on his phone.


    He knew he did not have an internet connection, but he still clicked on the apps subconsciously and tried to check for news.


    Chen Xin refreshed his apps but there was no signal in the bunker, all the news was from a week ago. The last news on his feed was about the failed rescue operation.


    Chen Xin silently stared at the news. He let out a deep sigh and was feeling depressed.


    The news represented the end for humanity, the end of their glory days. Humans faced a new era of difficulties and hardship.


    It could be said that this news was a wake-up call, reminding everyone that humans would struggle for survival in the long cold nights.


    Chen Xin motivated himself after a moment of sadness.


    Human civilization might be over, but they were far from losing hope.


    The glory of human civilization might be history, but humans were still alive!


    It was true that they fell into hardship, they were met with a shortage of food and all sorts of resources. The whole world was a dark winter dystopia!


    However, as long as humans existed, they should not give up hope. They could get through this! They would overcome any obstacles and rebuild their homeland!


    This unbreakable human spirit was the most valuable asset of humanity. It was how humans survived since Ice Age and got to the top of the food chain, the rulers of the world. Humans built civilizations and societies, humans even defied gravity and wandered in space!


    They did it because humans always had hope.


    It was like a spark of flame, it might be insignificant, it might look small, but it was everything.


    Hope carried humans through hardship and obstacles, again and again, passing down the flame of humanity through generations!


    The situation was bad, but our ancestors faced worse with only sticks and stones. We were lucky in comparison!


    A safe solid bunker was a better shelter than a cave from our ancestors.


    Warm clothes were better than animal fur.


    We replaced Ice Age creations with various functioning tools.


    Our war machines were far superior to the weapons of our ancestors.


    We were better at everything than our ancestors. There was no reason that we could not be like them, to find a way and get through obstacles, right?


    _____________________________


    Chen Xin recollected himself and turned on his laptop. He organized the information he had so far.


    He downloaded all sorts of information on his laptop before entering the bunker because he knew he would not have any signal down here. He copied a lot of stuff in his hard drive file.


    The information included tutorials and videos on how to maintain a greenhouse farm, how to fix a broken generator, how to fix cars, and reparation tutorials¡­


    Whatever Chen Xin could though of were all downloaded into his phone and laptop. He had no problem looking for information even without the internet.


    At least in the next few days, Chen Xin would not run into any issues with the information at hand.


    Of course, he could not miss out on novels, movies, and entertainment.


    Without the internet, Chen Xin felt like he could never see the endings of the novels he used to read. As for video games, he could only access the single-player games.


    However, for someone like Chen Xin had no access to electronic devices the entire week, even Poker or Minesweeper was good enough. Plus he had a lot of premium AAA video games on his laptop.


    Chen Xin finally got his hands on electronic devices, but he did not instantly play video games to relax. Instead, he checked for information storage in his laptop, he wanted to ensure no files were corrupted by the EMP shockwave. He looked at his notebook and created digital copies of his bunker upgrade plans on his laptop.


    Chen Xin took simple notes for convenience, but now he had access to his laptop so he could create a more complete Excel form. That way he could keep track of his plans and progress.


    Moreover, Chen Xin used CAD for simple illustrations for better planning.


    The easiest way to upgrade the bunker was to choose the general bunker upgrade from the system. It was the most convenient and fastest way, it was also the most direct way.


    However, Chen Xin only gained little survival points daily, it was not yet up to a hundred survival points. It was not enough for the general bunker upgrade, at least not in a short amount of time.


    ¡°Basic Simple Bunker¡±


    ¡°Upgrade Plan A ¡ª Defense level up, increase bunker ability to avoid disasters, increase comfort, technology in bunker level up +1, 12000 survival points required.¡±


    ¡°Upgrade Plan B ¡ª Expansion of bunker, increase the number of members allowed in the bunker, increase protection of resources, members allowed in bunker +5, 15000 survival points required.¡±


    These are the two options of bunker upgrading plans. Chen Xin ignored the high survival points that made his blood pressure went up, he only analyzed how he could benefit from the two options, how he could upgrade his bunker and increase his chances of survival.

 Chapter 34

    Chen Xin stared at the two plans on the system and analyzed them.


    The first plan was not hard to understand, a defense level up meant upgrading the build quality of the bunker.


    Chen Xin knew if he picked this route, he could avoid disasters. Small earthquakes, fire, landslide, etc. would no longer threaten his safety.


    As for the options of increasing comfort and technology in bunker level up +1, it was to increase his lifestyle quality.


    Upgrade Plan A was meant to be chosen for someone who lived in the bunker alone. It could benefit him.


    Chen Xin felt like this plan was more suitable for him right now.


    He was living in the bunker alone so he did not need to expand his bunker.


    Upgrade Plan B was not entirely useless to Chen Xin. It might come in handy in the future when he had a girlfriend or a wife. Why would he spend the rest of his life alone?


    More members meant more tasks could be done too. For example, if he had enough manpower, he would expand his greenhouse farm, turn it into a real big farm to plant vegetables and even fruits.


    It would not only improve his living conditions, but he could also trade for more resources.


    Chen Xin could tell it was a waste to rely on survival points to upgrade.


    He would rely on a second way to upgrade from now on. He would try to gather more items for upgrades so that he could reserve his survival points.


    The 12000 survival points could be reduced. If Chen Xin could gather a ton of high-quality steel and twenty bags of cement, he could reduce the survival points required by ten percent.


    Ten percent might not sound like much for something that required few survival points, but for a big project like this, ten percent meant saving 1000 survival points! Chen Xin could build a room with that.


    Chen Xin could not afford the general bunker upgrade. The rest of the content in his excel form was a room upgrades list.


    ¡°Modular Container Room ¡ª Bedroom, upgrade required 3000/4500 survival points.¡±


    ¡°Modular Container Room ¡ª Living room, upgrade required 3500/4200 survival points.¡±


    ¡°Modular Container Room ¡ª Washroom, upgrade required 800/1200 survival points.¡±


    ¡°Modular Container Room ¡ª Switchroom, upgrade required 2000/3200 survival points.¡±


    There were four modular container rooms in his bunker, they were also his main activity space.


    The more expensive upgrades were the bedroom and the living room. The cheapest would be the washroom.


    Chen Xin expected the washroom to be cheap, after all, it was just a small room next to the bedroom. The washroom contained a complete set of toiletries. It was basically like a normal washroom in a motel, it was decent.


    Even though the upgrade was cheap, Chen Xin was satisfied with what he had so far.


    The bedroom and the washroom were his priority despite being expensive, they were his main activity space.


    After all, Chen Xin already secured his survival condition, it was time to improve his living conditions.


    He did not forget that an improvement in his survival condition also meant an improvement to his daily round-up from the system. Chen Xin could improve his survival condition by improving his living condition.


    As for the switchroom, Chen Xin did not want to upgrade this room, it was unnecessary because the electric usage so far was not worth the upgrade. The switchroom upgrade was at the bottom of his list.


    According to his plans, the bedroom and the living room would be prioritized for the upgrades if Chen Xin had sufficient survival points.


    Unlike the bedroom, the living room could be split into different rooms.


    Chen Xin wanted a kitchen, a medic room, an entertainment room, a communications room. He planned to have a study area in the bedroom too.


    His kitchen items, medic items, and all sorts of electrical items were placed in his living room. It was not too shabby, Chen Xin was okay with that. However, he had the system, which required him to improve his living conditions. Chen Xin had to organize the rooms to improve his living condition.


    He did not know whether he would improve his daily round-up by doing so, but it was necessary for Chen Xin to try.


    Chen Xin was fine with a shabby kitchen because he was eating self-heating food. However, he wanted to stir-fry vegetables that he collected from his greenhouse farm, so he needed a better kitchen to cook better food.


    A communications room was a must.


    He was underground without an internet connection or any forms of communication with the outside world. The shortwave antenna was his only way to receive any outside signals. Upgrades for the communications room would greatly improve his chances of contacting the outside world.


    For someone like Chen Xin who could not step out of the bunker yet, it was very important.


    Chen Xin did not have social anxiety, although he was living alone and would not go to crowded places, he would still communicate with people through the internet.


    However, it was the apocalypse. He would be mentally ill if he kept staying alone like this.


    Even if Chen Xin could go outside when it was stable, he would not go out for no reason. He should not be communicating with others by yelling, right?

 Chapter 35

    Time flew by, it had already been a month since the end of the world. Chen Xin did not do much in the past month, he would wake up at the sound of his alarm clock. In the past, he would wake up whenever he wanted to.


    However, the bunker had no daylight. He could not differentiate between daytime and nighttime so Chen Xin set up his alarm clock to avoid not knowing what time it was.


    This was the first time he would set up an alarm in his entire life as a novelist.


    The routine lifestyle was refreshing to Chen Xin, he felt like it improved his health, it was a brand new experience to him.


    He had a lot of new habits following his routine lifestyle too. He would wake up, brush his teeth, wash his face. Then, he would tear open a packet of self-heating food as breakfast. He would exercise for ten minutes while waiting for his breakfast to heat up.


    His appetite would be better after a warm-up too.


    He would check on his equipment after breakfast, then fuel up his generator.


    Once he ensured the generator was providing electricity to the whole bunker, he would spend the rest of his morning tending to the greenhouse farm.


    He did not need to worry about weeds and pest insects, but he still had to water the plants and fertilize them.


    Planting and watering were relatively easy for Chen Xin. Although he had never done it before, he had his laptop video files to help him reach the standards.


    The vegetables had not flourished, but at least they were growing healthily. There was nothing wrong with it.


    Chen Xin could not stand fertilizing.


    He did not buy fertilizers when he moved into the bunker. He got soil from the garden of his neighborhood old farmer, it was good but the soil was not fertilized. The neighborhood old man had a garden in his house and used it for his own vegetables only, it was why the soil was not chemically processed or fertilized.


    He remembered when his neighborhood old farmer reminded him that the soil needed to be fertilized for the vegetables to taste good when he sold Chen Xin the soil.


    The fertilizer he was talking about was not chemical, it was¡­ natural.


    It was simply the dirtied water previously introduced in the recyclable water system. The fertilizer was fermented dirtied water in liquid form. The fermented process would produce a certain type of smell, also famously known as swamp gas.


    Farmhouses and countrysides would usually have a swamp site to dump feces and organic waste. The bacteria in swamp gas would produce methane gas. Methane gas could be used for cooking, warmth, lights, and generating electricity.


    Swamp sites were a common facility in the countryside of Vermillion. It was huge in the nineties. It used to improve the lives of the countryside people by processing feces.


    The recyclable system for water that Chen Xin installed had the same concept. The recyclable system used bacteria to recycle dirtied water, the organic particles in the dirtied water would be broken down and filtered out. Used water could not be dumped into a swamp site because it might have soapy liquid, detergent, shampoo, etc. These chemical ingredients would kill the bacteria in a swamp site.


    Chen Xin tried to use swamp gas as an energy source, but he realized he could not produce enough feces to attain swamp gas so he eventually gave up on the idea.


    However, a swamp site was important to recycle dirtied water.


    The smell from the fermenting tank was¡­


    Imagine a boys hostel filled with sweaty socks that had not been washed for a month, then imagine an expired jar that had not been opened for a month. It was kind of like stinky tofu or Surstr?mming.


    The acidic impact¡­ Chen Xin walked in with a gas mask but he still almost cried from the smell.


    Thankfully, the process tank was outside of the rooms. Chen Xin powered up the ventilations beforehand too. The smell would not waft through the entire bunker.


    The fermented liquid was collected in a plastic bucket that Chen Xin prepared in the greenhouse farm, then it was used on the soil with a ladle.


    Although the acidic smell was horrible, it was truly a natural fertilizer. It was organic and could help the vegetables grow healthily.


    After fertilizing the soil, Chen Xin had to water the plants. Halfway through watering, he suddenly realized the hose ran out of water.


    It shocked Chen Xin. He hurriedly ran to the water tank and the fermenting tank. He discovered his water tank that could store three tons of water was empty. The dirtied water process tank was only half full too.


    Chen Xin stared at the empty water tanks, he did not understand why this was happening. He had a recyclable system for water that could even collect water from the air, was the water used up?


    It was too late, there was no more water. He still had a lot of drinkable water stored up, but the water for his greenhouse farm was coming to an end.


    Chen Xin had to think of new ways to attain clean water, or else he would be facing a water shortage and forced to use drinkable water for his daily life.


    That was his last resort, he would not do that if he had another choice.


    Chen Xin had two choices.


    First of all, he could take a risk, step out of the bunker to look for a water source.


    A month already went by, the situation outside should have settled down by then. The cooling temperature would have stopped the fire. Step out of the bunker did not seem like much of a problem.


    Chen Xin was planning to do that anyway, he wanted to install the shortwave antenna outside the bunker to contact his companions in the group chat. If it was possible, he would like to trade resources with survivors in the same city.


    Chen Xin knew there was someone in the city without a greenhouse farm. He could bring fresh vegetables and trade things with her.


    However, there was a problem. How would Chen Xin bring back water to the bunker?

 Chapter 36

    Chen Xin could use a hose to fill up his water tank if the tap water supply from the area still worked. He had used a long hose from the construction team to fill up his water tank when he was still building the bunker.


    However, the construction team was gone, and Chen Xin did not have a long hose. Furthermore, he did not know whether the tap water supply still worked.


    Since there was the threat of fire and meteorites, the water plants might not have survived the disasters. It was concerning.


    Also, even if the water plants did survive through all that and the government ensured its operation, how would Chen Xin transfer tap water into his tank?


    A hose? He did not have a long hose, all he had were a bunch of 1.5L mineral water bottles.


    Some might say to just use the mineral water bottles, go for it!


    A simple scientific explanation of water mass and weight (also known as water density) needed to be carried out before doing so.


    The density of purified water was 1. A liter of water meant 1 kilogram, putting a ton of water as 1 unit.


    His water tank could store three tons of water, which meant he needed 3 units of water. He had about thirty 1.5L mineral water bottles. If he filled it all up, he could carry 45 liters of water, it was 45 kilograms in total. About the weight of a girlfriend.


    Putting Chen Xin¡¯s physical abilities and time concerns aside, how many times did he need to go back and forth to transfer the water?


    It was not a hard math question, even a pre-schooler could solve it.


    Three tons of water was equal to three thousand liters. Chen Xin could carry 45 liters of water each round, using a simple math equation, Chen Xin had to go back and forth around 67 times.


    Imagine carrying a girlfriend back and forth 67 times in one go.


    Chen Xin might do that if it were just a few couple times. If it were only ten rounds, he would find a tap water supply and fill up his mineral water bottles.


    However, Chen Xin lost his will to move at the thought of going back and forth 67 times.


    He might be able to pull it off if he split up the transfer rounds, but there was no secure and stable water source yet.


    He had to think of another solution. He considered a system upgrade.


    He avoided this at first because the system could not create something out of nothing, it could only upgrade what was already there.


    Chen Xin had no reliable water source, whether it be tap water supply outside the bunker or creating a water well inside the bunker. He had not prepared for this.


    Chen Xin thought about building a water well for the bunker so that he could attain a new water source even if he ran out of drinkable water.


    The construction team hired by Chen Xin did not know how to build a well, Chen Xin did not bother finding someone with the skills to build one either.


    Chen Xin was in the south part of Vermillion, it was nearby Daze Town. Daze Town was known for its underground water resources, a lot of water pumps could be seen in the countryside too.


    Chen Xin wanted a water well in the bunker but he ran out of time, so he gave up on the idea.


    Chen Xin wanted to upgrade the water supply. He was unsure of whether a well could be created along with the upgrade.


    However, it was better than running back and forth 67 times. Chen Xin had to risk it all and try.


    Thankfully, the survival system did not let him down.


    ¡°Water Shortage¡±


    ¡°Upgrade Plan A ¡ª Water system level up, higher chances of dirtied water being recycled, +2 units of water tank storage, recycled water +1, 500 survival points required for the upgrade.¡±


    ¡°Upgrade Plan B ¡ª Water system level up, higher chances of dirtied water being recycled, +1 water pump, +5 units of water tank storage, 300 survival points required for the upgrade.¡±


    ¡°Note ¡ª The water pump could reach 50 meters underground. If your bunker did not have water 50 meters underground, water could not be pumped.¡±


    Chen Xin let out a sigh of relief when he saw the water pump. Chen Xin glanced at the upgrade plan note and ignored it.


    He was on the southern side of Vermillion, home of many lakes and rivers. Being situated near Daze Town meant he access to underground water. Chen Xin had to avoid accidentally digging into a water source and ensure the bunker was waterproof when he built it.


    Chen Xin did not need to worry about whether there were water 50 meters underground. He just knew there was. He had a manual water pump at his house before.


    Chen Xin instantly used the survival points he saved up for a month on Upgrade Plan B.


    The net-shaped upgrade light shined and covered the water system.


    Chen Xin once again witnessed the glory and wonder of the system. A water pump formed out of thin air!


    Chen Xin was amazed. He checked on the water pump and looked for the switch in the switchroom. He turned on the water pump and it started operating.


    It was a small water pump, but it was still working with loud buzzing noises.


    The water pump was noisier than the generator, Chen Xin was observing it closely as if the water pump were a small brat throwing a tantrum. He hoped to hear the sound of water flowing in.


    Chen Xin was nervous, he knew there was water but what if the water was slightly deeper underground?


    The ¡®brat¡¯ did not disappoint him. Chen Xin was just starting to worry when the small pump had loud flushing noises. Soon, the buzzing noise was replaced with the sound of water pumping in. The water tank sounded like it was being filled up.


    The water was being pumped in!

 Chapter 37

    The water supply was refilled and the water tank enlarged. Chen Xin felt like he got the help he needed, and solved his emergency shortage problem.


    He could get water from the water pump whenever he needed it so he did not need to worry about water shortages anymore.


    He did have a recycling system for water that could transform air into purified water, but he could not achieve a pure vacuum state like a space station. Therefore the success rate was not always 100%. Truthfully, it was already impressive that the recycling system could reach a 90% success rate.


    Each recycled round indicated a 10% wastage. Three tons of water was nothing because according to statistics, an average Vermillion citizen would use 130-300 liters of water each day. That would amount to 4 to 10 tons of water used each month.


    That was excluding the water used for the greenhouse farm.


    Chen Xin figured he would last a month before he had any water shortage issues since he was saving up hard.


    However, he now had a water pump and a big water tank that could store eight tons of water. Chen Xin could finally use water more liberally. He felt like he was living like an astronaut before this. He would only use a wet towel to wash his face every day and whenever he took a bath, he would wet his body and lather up with soap, then wash it off in one go and would hurriedly turn off the water pipe.


    Chen Xin felt confident that his living conditions had increased.


    He believed his daily round-up would increase by at least 1 point.


    Chen Xin turned off the water pump after the tank had been filled. Then he continued to water the plants in the greenhouse farm.


    The farm was built in mind with feeding just him alone so it was modestly sized.


    Chinese cabbages and cabbages took a month to grow. When Chen Xin harvested the vegetables, he realized there was too much and he might not be able to finish it.


    Chen Xin did not know how much he harvested because he did not have a scale.


    He roughly had at least a hundred cabbages, excluding the other vegetables. He used half of the farm for planting carrots too.


    If he ate a head of cabbage every day, it would last him half a year.


    Chen Xin felt like he could finish it even if the cabbages were well preserved.


    He decided to keep part of it and trade the rest to others.


    It was his initial plan, after all. Chen Xin needed to step outside the bunker and check on the apocalyptic world.


    He stored the vegetables in a big plastic container and thought about how to deal with the vegetables.


    The big plastic container was set aside in the bunker, it was originally placed there to store items but Chen Xin realized there were not any items left to store. He did not expect to use it like this but it served the purpose.


    Chen Xin estimated the number of cabbages while storing it in the container.


    He had about eighty heads of Chinese cabbages. He placed them in two different containers, it seemed like it was about 300 to 400 grams. Chen Xin had around one-and-a-half-container-worth of cabbages, it was about 200 grams.


    The Chinese cabbages that Chen Xin planted were the fast-growing type. It was grown in a room with a specific temperature too, so it was fat and healthy. Chen Xin could eat a head of Chinese cabbage for a week.


    A Chinese cabbage could be stored for up to three to four months at a chilled temperature.


    Chen Xin stored one container of Chinese cabbages and half a container of cabbages in his storeroom. He moved the rest to the garage, preparing it for trading.


    He scratched his head when he placed it in his storeroom. Chen Xin felt like it was time to upgrade his storeroom, he should put it on his list too.


    Chen Xin stored mineral water and self-heating food in his storeroom, so there was no need for a refrigerator when he built this bunker.


    However, he had to consider it as an issue after he harvested the vegetables.


    Chinese cabbages could last for a while, but cabbages would be moldy after a few days.


    Chen Xin needed a refrigerator or a chiller.


    Some might say to place the vegetables outside since the temperature outside the bunker was freezing, right? Doing that would only end up damaging the vegetables. Moreover, the vegetables might freeze till it was rock hard, rendering them inedible.


    Also, it might not be freezing outside!


    Since the bunker was underground, he would have felt the cold in the bunker if it were freezing outside.


    Soil would spread temperature slowly. A temperature was not as easy to read if it were taken underground, but temperature changes from the surface would still spread underground eventually.


    According to scientists, being a thousand meters underground would have a temperature increase of 25 degrees celsius. Every hundred meters after that would have a temperature increase of 3 degrees celsius.


    Chen Xin was not feeling very cold. He would wear a single layer long sleeve shirt and a jacket.


    It was not hot in the bunker either. The vegetables might last for a while, but even if the temperature was cool, the vegetables still would not be well-preserved unless he had a refrigerator. It seemed like it was necessary if he wanted to better store food.


    Thankfully, it was the apocalypse. He could probably easily trade fresh vegetables to someone with an extra refrigerator. He might be able to trade other resources too.


    Chen Xin was ready to step outside the bunker.

 Chapter 38

    Chen Xin had to check on his transportation capabilities since he was stepping outside.


    Chen Xin had an SUV so he did not need to clear out the backseat for two containers to easily fit inside his car. However, he might not be able to fit a refrigerator inside.


    He had to figure out how to move a refrigerator back to his bunker if he traded the vegetables.


    Maybe he could tie it to the car roof? Or maybe he could place the refrigerator at an angle and tie it with ropes?


    It was not easy to carry it back with an SUV.


    However, it was not that big of a deal, if Chen Xin could get a refrigerator, he could find a way to bring it back to the bunker.


    He lived in the city for many years and had a lot of friends here. He could easily use fresh vegetables to get help.


    Despite that, Chen Xin was unsure of how many friends would help him out. He was not sure if they were still alive or are struggling in the government shelter.


    The car was abandoned for a month and had a layer of dust on it. Other than that, the car was okay, Chen Xin refueled it and was ready to go.


    Chen Xin prepared himself to go outside the bunker.


    He was unsure of the situation outside so he needed to take precautions. For example, there might be toxic gases outside, he also needed to consider the temperature and any other potential hazards.


    Chen Xin had to protect himself even if he had a car.


    Chen Xin took out his outdoor gear. His windbreaker sportswear would help him avoid bugs, it was waterproof and great for staying warm too. However, it would lose its warmth if it got wet.


    Outdoor hypothermia was dangerous even in the summertime, plus it was like winter out there, he had to wear clothes that would keep him warm.


    Apart from the specialized clothing, Chen Xin brought his gas mask along with him. He was concerned about the air quality outside.


    There was a wildfire releasing all sorts of toxic gases so Chen Xin had to make sure he could avoid the smoke.


    Chen Xin was ready to go. He hesitated and reached for his weapons.


    The Vermillion government did not give up and ensured order during the apocalypse. They provided citizens the government shelter too and maintained control. However, Chen Xin could not be sure of what the situation outside was.


    Law and order existed before the apocalypse and the government bunker, but what if they no longer had a bunker?


    Chen Xin was not sure if the world was as peaceful as he remembered.


    Weapons were a necessary precaution, it was more effective than fumbling around when faced with danger.


    He hung his EDC equipment on his clothes, placed a dagger in the back, hesitated then placed another dagger in his boots. He took his ASP stick that he hung on the keychain hanger.


    Chen Xin was confident in his fighting skills, he believed with these weapons he could handle two to three men, as long as they did not have a gun.


    Chen Xin made a mental note to upgrade the weapons one day. If he had a gun he would feel much safer.


    After he spent all his survival points on the water system, he was left with only 28 survival points. He would have to wait until next month for another upgrade.


    Chen Xin packed and brought along four 25L plastic containers, then opened the bunker gates.


    The big plastic containers were for fuel, he stored 4000 liters of gas fuel in the bunker and already used 300 liters.


    He spent another 50 liters on the car. Chen Xin needed to secure another source for fuel.


    There were two gates in the bunker, Chen Xin opened the inner gate and started the car. He drove into the tunnel connected to the outside world.


    Chen Xin stopped the car, got out, and closed the inner gate. He put on his gas mask, took a deep breath, and opened the outer gate.


    He was alienated from the outside world for a month, it had been a month since the meteorite crashed.


    What did the world look like during an apocalypse? How many people had survived? What was the situation outside?


    A myriad of questions filled his mind. He was confused and afraid to open the gates. He was scared to find out that it was the end of the world and he was the only survivor.


    It was not likely, but anything could happen in an apocalypse. Chen Xin could not ignore that possibility.


    He needed to find out and see for himself.


    He took another deep breath, forcefully pushed down on the gate handle, and pulled!


    The gate opened.


    There was no light outside.


    Chen Xin looked at a dark sky. It was supposed to be early afternoon, but it looked like it was late evening. The sky was covered with black clouds. Comets could be seen from time to time.


    The surface was charred from burning and covered in ash grey dust.


    Chen Xin found himself looking at an unfamiliar world.

 Chapter 39

    Safety first. Chen Xin should have turned on his car lights. However, he hesitated because he did not want to expose his location. He drove in the dark with the lights off to avoid any trouble.


    Thankfully, it was like late evening. Chen Xin could still see the roads clearly.


    Chen Xin lived in the suburbs, in bigger cities they would call it the countryside suburbs. His home was in a small town toward the south, so compared to big cities he was living in the middle of nowhere. There was not a lot of residences around, only a few farmers, it was like a quiet Townsville.


    Chen Xin loved the quiet of the countryside. He initially away from the city so he could focus on writing novels.


    Thankfully, Vermillion was great at building roads. The place where he lived was near a railway station so the roads were well constructed making his drive all the way to the city worry-free.


    The city streets were empty. It was not like those Hollywood apocalypse movies where cars were abandoned everywhere.


    This was what the apocalypse looked like in real life. Humans were informed of the meteorite three months prior to impact, everyone was evacuated into the government shelter. Why would the streets be filled with abandoned cars?


    If abandoned cars were seen, it meant that someone encountered a roadblock or a trap.


    There were no cars on the road, so Chen Xin did not face any problems driving to the city area.


    He left two tire tracks on the road due to the was white dust everywhere. Chen Xin looked at the cloud of ashy dust and felt a heavy pull in his heart.


    It was the ashes of the firestorm caused by the meteorite impact.


    Usually, he would pass by a river when heading towards the city area. It was not as beautiful as mother nature, but it was still an eco-friendly city and was even nominated as a great environmental city.


    It was all gone.


    The green mountains on the side of the roads were pitch black and covered in ash. It looked like charcoal with sprinkled snow on it. The plants were twisted like a horror movie, it was ugly and terrifying.


    The river was dried up, revealing a huge ditch. The bottom of the ditch had a blackish yellow tar. It looked like the infamous Deatholme in World of Warcraft.


    Chen Xin was familiar with this river. It was near his house, he used to come here on summertime nights to chill, he even walked with girls here too.


    The river was nigh unrecognizable. The high-quality wooden sidewalk was completely burnt with a few cement columns left.


    Chen Xin slowed down and looked at it sadly.


    The river was dried up, what about the things around the river? Chen Xin did not need to check it out to know everything was burned to the ground.


    Thankfully, the bridge connected to the city was still intact. The fire did not affect it, or else Chen Xin would not be able to enter the city.


    The city area did not fare any better than the suburbs.


    The beautiful eco-constructions were burned until there were only cement vases and uncharred trees. Road signs were burned until there was nothing left, even metal was burned to the ground, forming puddles of melted steel.


    A few stores Chen Xin used to frequent were also burned. The doors were melted and charred black.


    Chen Xin now felt the effects of the end of the world. It was like he time-traveled to a dystopian future.


    All the things he used to know, the lights, the busy streets, the skyscrapers, were all gone. The things he was familiar with, seemed so fragile in the face of the apocalypse.


    It was like a beautiful china vase. It was so stunning until it was dropped on the floor.


    Chen Xin always looked at war photos and documentaries for novel material reference, he was indifferent to a world in chaos. However, now that it happened to him in real life, he did not know what he had until he lost it.


    It was too late now, everything he knew was gone. A new generation of survivors was needed to rebuild their homes on this charred apocalyptic ground.


    Too bad it was only possible under non-apocalyptic circumstances. The temperature would only get colder. The world would stay in the dark and freeze eventually, it was the new ice age.


    Rebuilding was harder than it sounds at that point.


    Cement would freeze up before it was stirred, the ground could not be dug into, all the rivers and oceans would be frozen into ice¡­


    Earth was like a big refrigerator if there was no sunlight. Humans might not survive this after all.


    Rebuilding their home¡­ might be something Chen Xin would never witness for the rest of his life.


    However, Chen Xin should not think about that, it was not completely the end of the world despite doomsday already being here. It could be said that this was the last resort for humanity.


    As a survivor, he should try his best to gather supplies and resources. He needed to secure his bunker before the world froze completely.


    Chen Xin had a safe underground bunker and he picked up the survivor system. Staying alive was his number one priority.


    He needed to survive and needed to live more comfortably. That was all he needed to think about.

 Chapter 40

    Chen Xin drove past dilapidated yet familiar streets. He stopped at a junction and used a pair of binoculars to look at a building.


    The small building was at the corner of the junction. It was an L-shaped three-floored building that took up a wide space.


    The ground floor looked like it was tiled with stone yet it was all charred from burning. The stores with glass and metal doors were in luck. Although they were charred too, the insides of the store were still intact.


    The second and third floor was installed with anti-theft windows which were black with charring so Chen Xin could not see what was inside.


    This building was owned by one of his friends in the survival group chat. The ground floor was used for her outdoor gear shop. The second and third floors had an archery arena and a gym. The facilities were awesome but it was exclusive to members only, it was not open to the public.


    The building had two more floors underground. The first floor underground was a bar opened for members only. The other floor beneath it was her bunker.


    His friend was a lover of outdoor sports and was a fan of camping and survivalists. She did not come from an outstanding family, she moved twice when the city was expanding. She initially bought the land so she could move for the third time, but after she studied overseas and came back, she constructed this building and made a living by selling outdoor gear.


    The entire building was planned with the capability of housing an emergency shelter in mind. The underground floor was designed as a triple-proof bunker. Chen Xin used her bunker as a reference while he was building his own.


    The construction of the building was solid, plus her family was rich so she used the best construction materials. The building was alright despite the apocalypse with only the surface turning black from charring.


    Chen Xin looked up with his binoculars. He saw an installed antenna at the top of the building and smiled. He turned on his shortwave antenna on his car and adjust to their planned radio channel.


    ¡°Hello, hello, this is Author, I¡¯m at your place Nanana Ry¨±gaj¨­, over.¡±


    ¡®Author¡¯ was his nickname in the survival group chat. Nanana Ry¨±gaj¨­ was his friend. He called her Nanana Ry¨±gaj¨­ because they met in a Final Fantasy XIV game. She created a final fantasy Nanana Ry¨±gaj¨­ character with white hair and dark skin as her videogame avatar.


    She was the one who asked the big shots to take her, her sister, and her bestie to their bunkers in the group chat. She was also the admin of the survival group chat.


    She was the one who started the survival group chat and the group chat members were mostly her loyal outdoor gear customers. They were also members of her archery arena, gym, and underground bar.


    Chen Xin always called her Nanana Ry¨±gaj¨­ as her nickname, then he found out she was living in the same city. She was the one who introduced him to the world of outdoor sports too.


    Chen Xin was used to calling her by her nickname but her real name was Morgan, it was quite an artistic name.


    He felt nostalgic when he remembered how they got to know each other. It was a shame that they could no longer play together anymore because of the apocalypse.


    He sighed. He thought he was out of luck and the signal call did not go through. Suddenly, he heard something.


    ¡°Mayday! This is Nanana Ry¨±gaj¨­. Why are you here, stupid? Didn¡¯t you have a bunker? Why are you out?¡±


    Morgan sounded as energetic as usual. Her spirit could not be broken despite the apocalypse.


    ¡°As I said before, we have to keep in contact with each other after a month. I harvested a bunch of vegetables from my greenhouse farm. I recall that you did not have a greenhouse farm so I brought some for you. If you don¡¯t want it, I¡¯ll trade it with the government bunker.¡±


    ¡°Fresh vegetables? How much do you have? I want them all! What do you want to trade it with? Just tell me because I haven¡¯t eaten fresh vegetables for a whole month! I¡¯m almost puking from eating just spam!¡±


    Chen Xin listened to her unique accent and chuckled. Morgan was still the same Morgan.


    Chen Xin smiled, despite feeling depressed at the sight of the apocalypse, he was overjoyed at hearing the voice of his friend.


    He spoke on the radio, ¡°I have four hundred grams of fresh Chinese cabbages and cabbages. I can trade half of it for your spam and booze. I know you keep stock of those. If you have extra gas fuel or a refrigerator, I can trade you another hundred grams.¡±


    Chen Xin drove his car to the side of the building and waited for Morgan to come out.


    Chen Xin came around here a lot so he was familiar with the building. The three floors on the surface were not actually connected to the two underground floors. You could not walk to the underground floors with the building stairs. There was a side door next to the building with an elevator connected to the underground floors. Chen Xin had to wait for Morgan to open the door from the inside.


    Soon, someone with a gas mask on walked out from the charred side door. The person had a crossbow and was on guard.


    The person walked to his car and knocked on his window. Although the person was wearing a gas mask, Chen Xin could tell they were smiling.


    Chen Xin had on a gas mask too, he did not remove it. He waved and signaled that he was going to drive over there.


    The person nodded and pointed at the opened side door. They were signaling him to drive inside.


    Chen Xin drove into this familiar lobby. He did not stop driving, he went for the area that looked like a garage. Someone pressed the elevator button for him.


    Chen Xin drove in the elevator at their guidance.


    The person outside the lobby hurriedly closed the side door and walked with the person with a crossbow. Three of them walked in and they went down slowly through the elevator.


    Morgan had a huge elevator used for heavyweight loads. She was used to parking her car in her underground parking garage.


    Chen Xin drove out of the elevator and got out of his car. He took off his gas mask at the same time Morgan did, he said, ¡°Long time no see, Nanana Ry¨±gaj¨­.¡±

 Chapter 41

    "Long time no see! Ingredients Mo Qingyan directly hugs Chen Xin, holding him with two arms. She is unwilling to let go of him. Her face is full of emotion: "it''s so good that you''re OK! I''ve been crazy for a month underground. I can''t get in touch with you because of the situation outside. I''m worried to death! I''m relieved to see that you''re OK! "


    "How many times have you said, don''t call me ingredients." Chen Xin looked at the excited Mo Qingyan and gave a smile. Then he motioned her to let go of herself. He said with emotion: "I''ve had a terrible month. I can''t get any news from the outside world for a whole month. I almost ran out of water. It''s hard to say anything in a word."


    Having said this, Chen Xinye greets Mo Qingyan''s sister and best friend: "long time no see, Xin Xiaomei, Xiao Ding."


    "If you don''t let others call you food, you don''t call me xinxiaomei every time! How many times have you said that my name is mo Qingxin! " Mo Qingyan''s younger sister is obviously a little unhappy with Chen Xin''s address to her. Of course, it''s just a daily quarrel among friends. She doesn''t mean to be angry. She even has a smile around her eyes.


    As for one side, Mo Qingyan''s best friend is taking down the arrow from the crossbow and releasing the bow string to avoid accidental touch.


    After putting away the crossbow, she said to Chen Xin with some surprise: "writer, don''t you store a lot of fresh water? Why is it short of water? "


    Before entering the shelter, Chen Xin collected a large amount of bottled drinking water and tap water in purified water buckets. It was because of this that Mo Qingyan was surprised that Chen Xin said she was almost short of water.


    "You also said that those are drinking water. They are for drinking. I can''t take the drinking water to take a bath, wash clothes or water vegetables, can I?" Chen Xin can''t help shaking his head when he talks about this. If there is no system, it''s really hard for him to solve this problem: "fortunately, the problem has been solved, otherwise I will exchange fresh vegetables with you now."


    At this point, Chen Xin also opened his car trunk, patted two plastic boxes full of fresh vegetables, looked at Mo Qingyan and said with a smile, "here are 400 Jin of fresh vegetables. If you put them in the refrigerator, long Niang, it will be enough for you to eat for a month."


    Hearing Chen Xin say so, Mo Qingyan and her two companions immediately gathered around and looked at the two large plastic boxes in Chen Xin''s trunk, swallowing saliva.


    Although girls often say that eating vegetables is like eating grass and they can''t eat it, as long as they are normal people, they can''t avoid eating vegetables.


    It doesn''t matter for a few days or even a week, because in modern society, we can get enough nutrition from other kinds of rich food, but if we don''t eat vegetables for a long time, it will inevitably lead to malnutrition.


    But for Mo Qingyan, who was trapped in the refuge in the last days, although the food reserve was quite sufficient and the taste was not very good, they could still eat canned meat and lunch meat, but there were no fresh vegetables and fruits. They were very uncomfortable.


    Now I see two boxes of fresh vegetables in front of me, and three young girls feel that they just need to wash and eat them.


    After swallowing, Mo Qingyan turns her eyes away from the two boxes of attractive fresh vegetables, looks at Chen Xin and asks him, "what do you want to change, ah Xin?"


    Although she usually has a good relationship with Chen Xin, Mo Qingyan doesn''t have any idea of whoring in vain. Even to show her solemnity, she even changes her name to Chen Xin.


    In this era of doomsday, the original morality and law can no longer restrain the human beings who want to survive. Mo Qingyan, who had seen too many films and TV works about doomsday when she was studying in the United States, deeply understood this truth.


    At the end of the day, no matter how good the relationship was, it could not stand the test.


    Therefore, she hopes to exchange the fresh vegetables from the novice Chen rather than rely on the past relationship.


    What''s more, we can ask for it this time, but we hate our relationship with Chen Xin. The price we need to pay for getting fresh vegetables next time is not as simple as equivalent exchange.


    In this eschatological environment, the exchange of interests becomes more direct and explicit, and the old relationship and love can only get some preferential treatment. If you still want to take advantage or simply go whoring for nothing, the end result will be to hate your original friends and make yourself more difficult in this eschatological world.


    In the doomsday world, only unity and cooperation can make us live together. Mo Qingyan deeply understands this truth.


    Chen Xin was also very satisfied with Mo Qingyan''s attitude, nodded and said, "didn''t you just say that? Canned meat and wine, it would be better if we had gasoline or a refrigerator. "


    "I have a lot of canned meat, both lunch meat and real meat, and enough wine. How much do you want?" As for the exchange terms proposed by Chen Xin, Mo Qingyan agreed without any hesitation. As for the gasoline or refrigerator, she didn''t directly refuse: "I don''t have a lot of gasoline in stock. If you don''t want much, you can share it with me. If you don''t want the refrigerator, I have a big freezer of wine bar upstairs. You can drag it away."


    "If you can meat, two cases of lunch meat or one case of real meat, and one case of wine, is that ok?" Chen Xin looks at Mo Qingyan, thinks about it, and says the exchange ratio he can accept.Hearing the exchange ratio offered by Chen Xin, Mo Qingyan thinks for a moment and nods. There is no bargaining. This exchange ratio is acceptable to her.


    "In that case, I''ll give you a tin of luncheon meat and a tin of pork, plus a tin of Kim rum for 200 kilos of vegetables, but the tin of pork is a small can of 200g, isn''t it a problem?" Mo Qingyan looks at Chen Xin and takes out her exchange chips.


    Chen Xin nodded, indicating that there was no problem, and directly moved down a box of vegetables.


    "You can find something to load. I''ll take this box back." Chen Xin opened the box. The smell of fresh vegetables made the three girls'' eyes brighter, and the sound of swallowing was also very obvious.


    Mo Qingyan nodded, looked at her sister, and said to her, "Xiao Xin, you go to move the can and bring a plastic box by the way."


    With that, Mo Qingyan looked at her best friend: "ah Ning, go upstairs and move a box of Kim Lang Mu down."


    "I see. Where''s the key to the cellar?" Ding Ning looks at Mo Qing Yan and reaches for the key to the wine cellar.


    Mo Qingyan pulls off the key chain from her belt and throws it to Ding Ning.


    After all this, Mo Qingyan turns to Chen Xin and sends out an invitation to him: "ah Xin, are you in no hurry? Let''s talk? "


    "I''d like to know something about the city." Chen Xin nods and accepts Mo Qingyan''s invitation.

 Chapter 42

    Chen Xin is not addicted to alcohol and has no habit of drinking. However, after the doomsday, it is no doubt a consolation for Chen Xin to be able to put aside the pressure of survival and sit down with his friends for a drink.


    "That is to say, the current situation in the urban area is fairly stable, and the general situation is still under the control of the state?" While drinking the wine in the glass and listening to Mo Qingyan talking about the current situation in the urban area, Chen Xin finally put down a lot of worries.


    Mo Qingyan tilted her leg to the armrest of the sofa. She was lying on the wide sofa, holding her wine glass in her hands and nodding: "at present, the three large shelters built by the municipal government take in about one third of the city''s population, and restart the waterworks, power plants and railway stations. The basic living conditions are still guaranteed.


    Although there is limited time for water supply and power supply, only 12 hours of water supply and 8 hours of power supply are guaranteed every day, it is very difficult to guarantee water and power supply in this situation. I am also close to the two refuges of the shopping center and the city government, so I can rub some water and electricity from their lines, so as not to cut off the water and power supply. "


    Hearing Mo Qingyan say so, Chen Xin can''t help but feel envious: "then your condition is much better than mine. I finished the water pump these two days, but the water was almost cut off before."


    "It''s not as good as you think. Although the city government acquiesced in us to rub water and electricity, it''s the same as before. It''s not free." At this point, Mo Qingyan''s face became a little ugly. She spat and then continued: "although the city government is still in charge now, the people who work at the bottom have begun to be unscrupulous. The guy who came to me to collect water charges before dared to let me sleep with him! I really want to shoot him up and down the head with one shot


    In this case, although Chen Xin is very worried about the safety of her friends, looking at her now, Chen Xin knows that she has solved the problem.


    At the end of the world, although the state can still maintain the basic order because of the well prepared relationship, the old moral system has begun to collapse under the threat of the doomsday natural disaster, and some dark sides of human nature have gradually emerged after losing their constraints.


    The three large refuges directly controlled by the municipal government may be OK, but it''s inevitable that small refuges like Mo Qingyan''s family will be missed or even exploited.


    "No wonder I saw Xiao Ding holding a crossbow all the time just now. That''s what happened. So how did you deal with that guy? They will willingly give you water and electricity? " Chen Xin knows that Mo Qingyan must have solved the problem, but he is still curious about how she solved it.


    For this problem, Mo Qingyan just shrugged her shoulders gracefully and said with a smile, "I just asked Anning to find uncle Ding."


    "Oh ~!" Chen Xin made a sudden sound, and immediately understood how Mo Qingyan solved the problem.


    Uncle Ding is Ding Ning''s father and the captain of the special police team of the city police station.


    As the only legitimate armed force in peacetime, besides the army, who can control firearms, the importance of the special police force is self-evident after the end of time.


    For the city government, whether it can maintain the order of the three official shelters and other shelters in the city, large and small, and make them still obey the leadership of the city government depends on whether the city government can grasp the armed force of the special police force.


    As for the army, the city itself is only a prefecture level city. According to the military system of Yanguo, the army is divided into war zones. Although there are military divisions at the provincial and municipal levels, there are only militia reserves in the military divisions.


    Although the militia are also called soldiers, their training level, combat ability and armed level can not be compared with the standing armed forces such as the special police force.


    So in this doomsday environment, as the captain of the special police team, uncle Ding''s status in the city has undoubtedly been greatly improved. As his precious daughter, Ding Ning, naturally, no one dares to swat flies on the tiger''s head to provoke the aunt.


    However, thinking of the SWAT team, Chen Xin couldn''t help looking at Ding Ning, who was sitting on another sofa with Mo Qingyan in the same posture, and asked her, "I remember Xiao Ding, are you also a policeman? Don''t you have to go to the police station on standby at this time? Or did Uncle Ding open the back door for you? "


    "Nothing. My dad gave me a long vacation." Ding Ning''s mood seemed to be a little depressed. He took the bottle in his hand and poured a big mouthful of wine into his mouth.


    Hearing Ding Ning say so, Chen Xin clearly understands what she is now in.


    Obviously, uncle Ding loves his precious daughter and doesn''t want her to encounter any danger at this time, so he gives her a long holiday. Instead of going to work in the police station, he can stay in the shelter with sister Mo Qingyan, and the safety is undoubtedly much higher.


    Although this is power for personal gain, considering that it is the end of the world and the status of the special police force in the city, uncle Ding''s practice has been very restrained.


    And this operation in addition to make Ding Ning look like a deserter, there is no illegal place, even in the past, this is no problem.


    Although in an emergency, all the police in the police station will cancel their leave and return to the police station for standby, the police with a strong sense of responsibility will choose to rush to the front line even if they are suspended or can not go.Ding Ning just graduated from the police school last year. He was just in his hot-blooded youth. Now that he was hit by his father, it is conceivable that he was not in a beautiful mood.


    Chen Xin didn''t go to stir up Miss Ding, who was in a bad mood, so he continued to listen to Mo Qingyan and said, "is there any other refuge in the urban area besides the three major shelters?"


    "I know, I know!" Mo Qingxin immediately raised her hand to answer, and poured out all the information Chen Xin wanted to know like beans in a bamboo tube: "in addition to the three big refuges, there are refuges built by the state before the disaster in the municipal office building, the municipal police station, the riverside waterworks, the thermal power plant, the Binhu community, and the University of technology.


    Although it is not as big as the three refuges, the scale is not small. Besides, except Binhu community, all the others belong to government departments, and there are not so many people in the three refuges, so the living conditions are better. "


    Ding Ning nodded his head and added: "other places are not clear, but the shelter on the other side of the city police station is an air raid shelter reserved when the city police building was built. The infrastructure is better than the parking lot. In addition, there are basically only police officers and their families in the police station. The order is relatively stable, and the materials are relatively sufficient. It''s really better than the three major shelters It''s hard to do well. "

 Chapter 43

    After that, he gave Mo Qingyan two boxes of vegetables and exchanged them for a box of canned luncheon meat, a box of canned pork, a box of rum, 100 liters of gasoline and a large freezer.


    Chen Xin''s SUV can hold gasoline and materials, but he can''t get the big freezer back. The SUV can''t hold such a big thing.


    However, Mo Qingyan is very generous and agrees to Chen Xin to use her own car to help transport the freezer to his refuge. She doesn''t even need him to help with the transportation fee. After all, it''s easier for them to get gasoline in the city.


    After finishing all this, Chen Xin also gave up the idea of continuing to inquire about the situation in the urban area. Originally, he intended to take vegetables to other shelters to exchange materials, but since Mo Qingyan could exchange what he wanted here, he didn''t have to go to other shelters.


    After all, the vegetables in his hand are enough for Mo Qingyan and their small shelter with only a few people for a month, but a meal may not be enough for the big shelter.


    Under such circumstances, people may not pay attention to the exchange of goods and materials at the great refuge, and the goods and materials exchanged may not be as much as those exchanged from Mo Qingyan, but they may be missed.


    Although the urban refuge is still under the control of the city government to maintain order, but in this end of the world situation, the official wants to requisition your greenhouse, the city supplies a game of chess, let you move to the big refuge, the greenhouse to professionals to deal with what, Chen Xin a person has room to resist?


    Although this possibility is not high before the collapse of the current social order, since the risk of this possibility can not be ruled out and there is no need to go to the great refuge to exchange materials, Chen Xin naturally gives himself less trouble.


    As for communication with the great refuge, this is inevitable. But before finding a secure way of trading, Chen Xin thinks it is better to avoid communication with the great refuge for the time being.


    And now the situation in the city In fact, there is no optimism.


    While driving back, Chen Xin thinks about the information he heard from Mo Qingyan and analyzes the current situation.


    "The railway station can still operate now. Every once in a while, there will be trains carrying coal and a small amount of materials, so that the municipal government can guarantee the operation of the thermal power plant. Then the power supply in the urban area should be OK. Even if the temperature continues to drop, the railway transportation should still be able to guarantee." Chen Xin''s fingers are tapping on the steering wheel. While talking to himself, he is optimistic about the situation of the railway station, one of the three shelters.


    Railway station refers to the old passenger railway station in the city. There is the earliest underground shopping plaza in the city, but it was transformed into an underground hotel after the depression.


    It''s quite a big place, and there are several big shopping malls around it. Before, the city government specially connected the surrounding area and transformed it into a fairly large refuge.


    In addition, they are also backed by the railway station, which is a transportation hub. Under the current situation, their importance is self-evident. The municipal government will make efforts to ensure the normal operation of the railway station, so the situation of the refuge should be good.


    However, the old railway station is quite old, and the underground space has been reconstructed several times. Although the underground space must have been renovated when the government built the refuge before, it is an indisputable fact that the facilities are aging.


    So the conditions of the railway station shelter may be good, but the living environment should be the worst of the three shelters.


    As for the other two shelters, the shopping mall and the pedestrian street, they also have their own advantages and disadvantages.


    The shopping center shelter is the big shelter near Mo Qingyan''s home. It is mainly a large shopping center built in recent years. The underground is originally a parking lot and a large shopping supermarket, and the shopping supermarket itself is also attached with a logistics center, which has great advantages in material storage.


    Before the disaster, the city government had transferred a large amount of grain from the city''s national granary and transported it to various refuges. Because there were enough storage conditions in the shopping center, a considerable amount of grain was distributed, and the grain distributed by several surrounding communities was basically stored here.


    However, the problem here is that the shopping center is not big. After all, it is a shopping center newly built in recent years, surrounded by residential areas, so the place is really small.


    Even if the underground garages connecting several surrounding communities connect the surrounding areas, the place is only so large, and the capacity to accommodate the population is limited.


    On the other hand, on the other side of the pedestrian street, it was a civil air defense project built when the mayor was in office. Two streets were hollowed out underground, an underground pedestrian street was built, and the old pedestrian street was transformed into an underground square.


    In addition, there is the most prosperous commercial area in the city. There are many large shopping malls, which are connected underground. It can be said that they are equivalent to an underground city.


    Moreover, it is built according to the standard of civil air defense project. All facilities are relatively perfect, and the capacity is certainly good. It is the most populous of the three shelters.


    But this also brings a problem, that is, more people eat more, and the pedestrian street is full of shopping malls. There is no such large-scale supermarket and logistics center as the shopping mall. The material storage capacity is not good, and there will not be too much grain in reserve.On the whole, the Three Refuges have their own advantages and disadvantages. Relying on railway transportation, the railway station is an important channel for the city to obtain materials, and the existence of the refuges will not have any problems.


    In fact, the shopping center is not far from the municipal government. In addition, there is a large amount of grain stored here. Even if there was no connection between the shopping center and the municipal government during the previous transformation, the municipal government will certainly find a way to dig a channel between the two.


    On the contrary, although the living conditions on the other side of the pedestrian street may be the best, because there are too many people and there are no other advantages, they are likely to face the dilemma of lack of food and clothing in the future.


    As for other smaller refuges, they also have their own advantages and disadvantages, which will be difficult to clarify for a while.


    Chen xinsuoxing doesn''t think about it any more. Mo Qingyan''s refuge is with Ding Ning, backed by the special police force and the city police station. It''s much safer and more able to get good things.


    Thinking of this, Chen Xin thinks that his next development direction can completely improve the output of greenhouse planting, exchange vegetables for various materials he needs, and upgrade the refuge with materials, so as to save the cost of survival as much as possible, and upgrade more projects at the same time.


    With this idea in mind, Chen Xin has a new plan for the future development of his refuge.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 44

    Shilipo sword God is a kind of development idea, but it''s too meticulous. Although it''s the end of the world, it hasn''t reached the degree that the social order depicted in various film and television works has completely collapsed, the country no longer exists, all people struggle to survive, the dark side of human nature has been magnified infinitely, and all people have put away the good and want to do everything to survive.


    Now, of course, some dirty things will happen, and some dirty things hidden under the table will become more direct, but the basic social order still exists.


    In the absence of major changes, the pattern of the city has actually taken shape. The next step is to fine tune and stabilize the situation.


    Since the overall social environment is still stable, Chen Xin''s small refuge, which is far away from the urban area, will not be in great danger as long as it is not found and watched.


    Under such circumstances, Chen Xin, who has a relationship with Uncle Ding, can take a more bold development model and make himself develop rapidly by exchanging vegetables for resources.


    I''m afraid it will be the last autumn before the real cold winter. If we can''t seize the time when the weather is not very cold, we can get enough resources to develop shelters. When the temperature really drops to tens of degrees below zero, which is equivalent to the original temperature within the polar circle, it will be very difficult to collect and transport materials.


    Moreover, with the further reduction of temperature, more problems will be exposed.


    Chen Xin is not a person who thinks human nature too dark, and he will not speculate on others with the greatest malice.


    But the ugly side of human nature is an objective fact. No matter how much we believe in the beauty of human nature, we can not deny that some people really have a dark heart.


    Especially in the end of this itself is in the dark tone of the environment, the dark side of the human heart and the ugly side of human nature is to get the soil of growth, with the gradual deterioration of the living environment and more robust.


    This is the inevitable result of human nature, and it is also an unavoidable problem in the end world.


    That''s why the ancients used the saying of heavy allusion in troubled times, because in this precarious environment, people can do anything to survive.


    Only by showing unswerving determination and tough means can all the people with ulterior motives or panic be restrained and the fragile order be maintained.


    Now is the buffer period before the real crisis. Thanks to the sufficient preparations made by the state earlier, and the fact that the temperature has not yet dropped below freezing point, the living environment is not very bad, so the order is relatively stable, and all kinds of contradictions and problems have not been fully exposed.


    However, as the temperature drops further, especially to below the freezing point, and gradually approaches the polar temperature, the reserves of various shelters also consume a lot, and all kinds of survival problems will follow, just like the bubbles in the happy water of fat house.


    The environment will be worse than it is now. I don''t know how much. Without the means of self-protection, small shelters like Chen Xin and Mo Qingyan will be difficult to survive without support.


    Whether it is energy or food, it will become more and more difficult to obtain with the bad environment. For the small refuges that lack output, this is a desperate situation.


    For this point, both Chen Yu and Mo Qingyan have realized this problem in their previous discussions.


    If there is no system, Chen Xin may worry about this problem, but now that there is a system, these problems can no longer perplex Chen Xin.


    As long as we get enough supplies during this period, we can further upgrade the shelter, make the greenhouse produce enough food, and upgrade the power system into a self-sustaining energy system


    Chen Xin believes that as long as he has these, he will be able to survive well in this end of life.


    As there were no traffic lights on the road, they quickly returned to Chen Xin''s refuge. After Chen Xin opened the door, Mo Qingyan took the lead in driving into Chen Xin''s refuge.


    With the help of Mo Qingyan and Ding Ning, he lifted the freezer from their van and put it in the storage room. Chen Xin then said to the two people, "thank you, long Niang and Xiao Ding. You''ve really helped me a lot. I can''t get it back on my own


    "You are welcome to the ingredients." For Chen Xin''s thanks, Mo Qingyan and Ding Ning don''t care much. After laughing, they look at Chen Xin''s refuge.


    Although the appearance of Chen Xin''s shelter is obviously not as good as that of Mo Qingyan''s home, which was decorated by the decoration team at the beginning of construction, Mo Qingyan and Ding Ning are keen to find that Chen Xin''s shelter is much warmer than theirs, and the air is not muddy at all.


    "Food, you''re a good shelter! Although buried in the mountains, the air is not stuffy at all! You paid a lot for the ventilation system, didn''t you? " Mo Qingyan looks at Chen''s upgraded ventilation system and asks him.


    "At that time, everything was bought as a whole, and the integrated container board house, in order to save trouble, I chose the best one to buy everything." As for this issue, Chen Xin has been directly vague about the past. After all, he can''t explain the system upgrade.However, this problem has not bothered him for long, because the system directly displays a piece of information. The concept of an information state attached to something upgraded by the system is vague. People who see these things will subconsciously think that it is reasonable, and will not think that these things are abrupt or strange.


    In order to play the game of survival, the aborigines of the primitive planet would not notice anything unusual and avoid interfering with the primitive civilization. However, Chen Xin saved a lot of time to explain, so that he could confidently and boldly use the upgraded system.


    And this also makes Chen Xin have new ideas. Maybe even if he takes out power armor and machine armor, which are big toys in science fiction works, it won''t make people feel strange?


    Once this idea came into being, it was out of control. Chen Xin couldn''t help but imagine that he would be able to sit in the body he liked in those science fiction works in the future.


    "Writer, do you have a heater here? How do you feel much warmer than ours! " While Chen Xin was thinking about what kind of body he should open in the future, Ding Ning was curious why Chen Xin''s refuge was so warm: "it seems that if we can''t stay in the city, we can really move to you!"


    "Ha ha, I don''t dare to run uncle Ding''s baby daughter. He has to break my leg." Hearing Ding Ning''s words, Chen Xin shrugged his shoulders humorously.

 Chapter 45

    After serving Mo Qingyan and Ding Ning a meal at their own shelter, Chen Xincai sees them off.


    After they left, Chen Xin''s shelter was quiet again.


    Power on the freezer, debug it and make sure it starts to work. Chen Xin put the previously harvested vegetables in and refrigerated them at low temperature to ensure that they won''t rot.


    In addition to vegetables, canned luncheon meat and canned pork exchanged from Mo Qingyan were also put into the storage room by Chen Xin. Instead, the box of wine was moved to his bedroom by Chen Xin. After he removed one bottle and put it in the bedside table, the rest was stuffed under the bed.


    Although he usually doesn''t drink too much, in this end of life, a drink before going to bed can relieve his nerves and make him sleep better. So this time, Chen Xin went out of his way to find Mo Qingyan to exchange a box of wine.


    What''s more, these things will become extremely rare with the coming of the end. After all, wine making needs food. When people are hungry, there is no extra food to make wine.


    These wine from before the end of the world will also become a rare and valuable resource, and will become more valuable as the end of the world lasts longer.


    However, Chen Xin doesn''t have the idea of hoarding wine as materials. On the one hand, he has the system in hand. He just needs to upgrade the shelter. When the greenhouse has enough output, it''s not difficult to make wine. He doesn''t need to hoard it.


    On the other hand, it will take a long time for Chen Xin to wait until the wine becomes very valuable, and such a long time is enough for him to have the ability to make wine, and expand the planting greenhouse, so that the grain yield can support his brewing.


    Of course, some treasures in Mo Qingyan''s cellar are very attractive to Chen Xin. Maybe you can find her to exchange some good wine in the future?


    Chen Xin had this idea in his mind. He couldn''t help thinking about it, but he didn''t think much about it. It''s not something that needs to be worried for a while.


    Among the materials exchanged from Mo Qingyan today, what Chen Xin really thinks should be hoarded is canned pork.


    At the end of the world, the original food output of human beings has been basically reimbursed. Naturally, there is no way to raise poultry and livestock. Meat resources will become very rare, even more than wine to some extent.


    After all, wine can be brewed by growing grain in the greenhouse, but pork, beef


    Even if the country has built underground farms before the end of the world, these things are destined to become luxury goods on the table of a few people, instead of going into ordinary shelters, just as they were before the end of the world.


    Although the country did make a plan before the end of the world about what the refuge should rely on to get food after the end of the world, the taste of mushroom and mouse meat No one will think that these things can be the same as pork and beef.


    Of course, maybe we can look forward to the taste of synthetic meat?


    After all, if there is a demand, there will be a market. In the near future, artificial meat may be popular. The improvement of taste makes it taste more like meat. It should become a just need.


    However, for Chen Xin, it allows him to look forward to whether the function of animal breeding will appear after the upgrade of the planting greenhouse.


    If we can get the function of animal breeding, maybe Chen Xin can get a stable source of meat.


    Although people will not die if they don''t eat meat, malnutrition is not the necessary condition for survival in the last days. The intake of animal protein from meat is a necessary factor for maintaining human health and balanced nutrition.


    Although it is not easy to be able to eat well in the end, it is obvious that it can greatly improve the quality of life in the end.


    But there is a problem that still bothers Chen Xin, that is, where to find the animal''s mother.


    The system upgrade may enable the shelter to have the ability to raise animals, but Chen Xin''s system only has the function of upgrading. He is not sure whether several live animals can be attached randomly after upgrading the shelter''s ability to raise animals.


    It''s not easy for him to see living animals in this environment.


    But maybe there will be animals in the sanctuary? Apart from other things, mice and earthworms are two of the three important food sources prepared by the country for the end of the world before the end of the world. They plan to provide valuable food for the survival of the end of the world together with mushrooms.


    Just eating rats and earthworms This makes Chen Xin, who has not yet entered the state of "what to eat and what to eat" in the last days, feel somewhat baffled.


    Although mouse meat can be regarded as a kind of meat before the end of the world, although it is a bit curious, it can also be regarded as a decent food. As long as the sanitary environment is controlled, mouse meat can be regarded as a good source of animal protein in the end of the world.


    As for earthworms, few people really ate them before the end of the world, but in wandering earth, the earth was frozen. After human beings entered underground life, the main source of food was edible earthworms, and the concept that earthworms could eat was understood by people.Now the environment of Bluestar is quite different from that in wandering earth. After all, the environmental problems we are facing are almost the same, except that Bluestar is not as extreme as wandering earth, and human beings are not living in the underground city thousands of meters below the planetary engine.


    Of course, these gaps are caused by the technological gap between the film and the reality. After all, for the real human beings, it''s almost the same to dig a hole thousands of meters deep, but if we want to dig an underground city thousands of meters deep


    This is beyond the limit of what human technology can do now, and humans don''t really need to dig such a deep hole.


    In wandering earth, we dig such a deep underground city because of practical needs. In reality, people want to avoid the extreme cold in the last days. Although digging deep enough, it''s a good way to get warm with the help of ground temperature, the existing technology still limits us to do so, and it''s really unnecessary.


    Although the existing technology of mankind can build an underground city, for example, Montreal in maple leaf country has a 17 kilometer long underground city, which was built only in the middle of the 20th century, more than half a century ago.


    But the depth of the underground city is only the depth of the underground buildings under normal circumstances, which is equivalent to the depth of the existing underground pedestrian passageway or pedestrian street. It is not exaggerated to the depth of 5000 meters below the surface in wandering earth.


    In fact, under normal human conditions, it is almost impossible to construct at this depth.


    Moreover, although the underground city of Montreal is not deep, it can withstand the long winter of 40-30 degrees below zero for four or five months every year.

 Chapter 46

    For human beings, although the environment of tens of degrees below zero is indeed a forbidden zone for life, which is not suitable for human survival at all, even in the worst polar environment, human beings have also built permanent polar scientific research stations, and the scientific research stations are not buried deep underground, but directly placed on the surface.


    The low temperature of dozens of degrees below zero is indeed a desperate death, but with the current human science and technology, there is no problem to build a warm and comfortable scientific research station in this environment.


    Taking Yanguo''s scientific research station in the polar region as an example, the container room is sprayed with 120mm thick polyurethane insulation layer, and then decorated with outfitting board. It is both warm and beautiful, and can completely resist the freezing temperature of dozens of degrees below zero in the polar environment.


    Of course, the scientific research station itself does not produce temperature, even if the insulation is good, heat exchange is still happening, so the scientific research station itself still has heating equipment.


    But this is enough to prove that the existing human technology in the face of cold and low temperature really does not need to dig thousands of meters underground.


    With the existing scientific and technological strength of mankind, as long as the shelter is well insulated and protected, and equipped with reliable heating equipment, it is enough to ensure that a shelter can be warm and comfortable in the environment of minus tens of degrees.


    But reliable heating is not so easy to guarantee in this era of doomsday.


    Taking polar scientific research station as an example, there are generally two heating methods, electric heating and fuel heating.


    Because scientific research stations usually generate electricity 24 hours a day, larger scientific research stations usually use indoor electric heating for heating. This way of installation and maintenance is simple and easy, and can control the temperature at will, clean and clean. Sometimes, most of the power of scientific research stations is used for heating. When the temperature of the external environment is low, it is easy to cause overload of the generator, and improper use is also easy to cause electrical fire .


    Some scientific research stations use oil fired boiler as the main heating equipment, similar to the ordinary heating in northern China, which requires additional installation and maintenance of heating equipment, but it is not prone to electrical fire and other accidents, which can effectively reduce the generator load.


    In addition, some small scientific research stations in summer only have simple gas heating equipment. They use special gas heating to burn liquefied gas or natural gas in tanks indoors, but they need to pay attention to ventilation and pay attention to the concentration of carbon monoxide in the air at any time to avoid carbon monoxide poisoning.


    These three heating methods are mature and reliable. Although they have their own advantages and disadvantages, they can meet the needs of shelter heating.


    According to Chen Xin''s understanding, the three large shelters in the city are all built with additional boilers for heating, but they are not burning oil, but coal.


    Yanguo''s oil reserves are not particularly abundant, but its coal reserves are relatively abundant. After all, Yanguo''s oil reserves are the ninth in the world, but its coal reserves are the third in the world.


    What''s more, oil is produced from crude oil, which can''t be burned directly. It needs to be processed into gasoline, diesel and kerosene before it can be burned.


    But coal can be burned directly when it is dug out, so under the condition of ensuring railway transportation, coal burning is undoubtedly more cost-effective than oil burning, and it is stable and reliable.


    Therefore, it''s a very good choice for large-scale shelters to use boilers for heating. As for the extra maintenance work, the least valuable thing in the end is manpower. Tens of thousands of people live in a large-scale shelter, and they don''t worry about finding people to work.


    For the shelters which are not so large in scale, there is no need to adopt such a way. Under the condition that the power supply can be guaranteed, they can use electric heating for heating. There is no need to install heating boilers.


    Private shelters like Chen Xin''s and Mo Qingyan''s can basically meet their heating needs by installing a heating air conditioner or two electric heaters. It''s not practical to install boilers because they have money to burn and they have brains to smoke.


    However, this is a wake-up call for Chen Xin. In the shelter upgrade plan, the heating system should be put on the agenda.


    Although I have prepared an electric heater and blanket for myself, isn''t it good to upgrade to make my life more comfortable? Why do you have to wear cold proof clothes indoors and sleep with three quilts?


    Chen Xin thought so, and habitually took out his notebook, wrote and drew on the paper, considering the next upgrade plan of the refuge.


    The notebook is now written with four items, power supply, lighting, food and medical treatment, in the order recorded by Chen Xin. After thinking about it, Chen Yu added heating before lighting.


    The power supply system must be the top priority option for upgrading, because in the other four projects on the notebook, except for the medical treatment which is not a priority, the other three projects will increase the power consumption of the refuge, so upgrading the power supply system and increasing the power generation of the refuge is a must.


    Moreover, Chen Xin must also consider the fuel consumption caused by power generation. According to his current electricity consumption, the average daily gasoline used for power generation needs ten liters. With the increase of electricity consumption, the fuel consumption is bound to increase. Chen Xin must consider the supplement of gasoline and obtain a more durable and efficient power generation method.


    If it''s normal, the only long-term self-sustaining and efficient power generation method Chen Xinneng considers is nuclear power, which he can hardly touch. However, for Chen Xin, who has a system, geothermal power generation and geomagnetic power generation, which are still in the stage of science fiction and laboratory research for human beings, are all in his future upgrading plan.Therefore, Chen Xin is not worried about how to obtain an efficient and sustainable power generation method. He has been upgrading the refuge, that is, as long as there is enough survival for continuous upgrading, Chen Xin believes that even black technology power generation methods such as antimatter reactor or artificial sun can be upgraded.


    Although these sci-fi technologies are too far away for Chen xinlai, and the survival needed is astronomical, under the powerful power of the system, these are indeed things that can be expected.


    Although the future is promising, it''s still too early to think about these things. The most important thing now is to re cultivate and plant new vegetables on the land vacated from the previous harvest of vegetables in the greenhouse, so as to find Mo Qingyan to exchange the materials needed for upgrading next month.


    However, thinking of exchanging materials, Chen Xin thinks that he should make a list first to see what materials he needs now. In this way, he can find Mo Qingyan to exchange materials with a definite aim, and let her prepare in advance, so as to save time.


    You know, even if Mo Qingyan has a relationship with Uncle Ding, it takes time to get supplies.

 Chapter 47

    Now that it''s decided to exchange vegetables for materials, it''s obvious that the greenhouse is the place where Chen Xin needs to upgrade most.


    At present, half of the land in Chen Xin''s greenhouse is planted with carrots, which will take about two months to harvest. The other half of the land was planted with lettuce and cabbage before. Now that it has just been harvested, Chen Xin needs to re fertilize the land, and then turn over the soil to re sow new seeds.


    At the same time of re fertilizing the land, we also need to carry out ploughing, which is commonly known as plowing or arable land.


    In this way, the caked part of the soil will be broken to make the soil loose and more convenient for the growth of crops. At the same time, the fertilizer can also be turned into the depth of the soil, so that the crops can better absorb the nutrients in the fertilizer.


    Ploughing is one of the most important parts of the whole farming process, and it is also the most tiring of all farm work. This is why there were cattle and even war horses in ancient times.


    Because it''s too tired to turn a piece of land by manpower alone, the use of animal power can greatly save manpower, improve the efficiency of cultivated land and save time.


    After all, cattle farming and human farming are two completely different concepts.


    However, Chen Xin''s greenhouse is too small, and he has no cattle to use, so he has to dig the land bit by bit with his own hoe.


    Fortunately, Chen Xin''s land area is not large, and the temperature of the greenhouse is constant. He doesn''t have to catch up with the farming hours. He just needs to plant the seeds after digging.


    However, even so, it took Chen Xin more than half a day to complete the cultivation of 50 square meters of land and re sprinkle the seeds.


    Looking at the land he had finished plowing, Chen Xin hammered his back. He felt that doing farm work was really a tiring job. At the same time, he also thought about whether he should upgrade his farm tools when he was planting greenhouses, so as to improve the efficiency of farmland.


    With the upgrading of planting greenhouse, the planting area will certainly increase, and the increase of planting area will inevitably lead to the increase of workload.


    Although there is no other thing to do in the shelter, and it''s good to do farm work, this kind of physical labor really makes Chen Xin, who has never done farm work in the first 30 years of his life, feel a bit hard. Moreover, it doesn''t matter if the area is small only by manpower. When the planting area increases, the use of mechanical force is the right way to improve efficiency.


    Maybe you can find Mo Qingyan to change some small agricultural machinery? Although the precious survival can be used to upgrade farm tools, Chen Xin thinks it should not be so wasted. After all, small agricultural machinery, even in this era of doomsday, is not very difficult to start with.


    In addition to small agricultural machinery, Chen Xin also plans to get a few additional fill light lamps, which are necessary tools for planting greenhouses and materials for upgrading them.


    As for the other materials for planting greenhouse upgrading, they are only steel and cement, which are basically the building materials that will inevitably be used in the expansion of planting greenhouse.


    Of course, if Chen Xin adds all kinds of equipment needed for hydroponic cultivation to the upgrading materials, in addition to expanding the land area of the greenhouse, Chen Xin can also produce a layer of hydroponic cultivation plates, so that the planting area of the greenhouse can be doubled.


    This is also the difference between using material upgrade and using survival upgrade. Using survival upgrade, you can only choose one of the upgrade schemes given by the system. I can''t choose all of them in one upgrade.


    However, there is no such problem when upgrading with materials. As long as all the materials needed for upgrading are met, there is no need to consider the problem of one or two. You can upgrade at one time, and both options are required.


    As for the functional differences brought about by the two upgrading methods, Chen Xin understands that this may be the function set by higher civilization in order to add fun to the survival game when it was making this system.


    After all, for the higher civilized individuals who can play the survival game, what they want is a better game experience.


    If you just live in a certain place, and then play doomsday survival by accumulating survival upgrade items, it obviously makes people feel a little negative, and the game experience is poor, after all, there is no real sense of participation.


    Maybe I will spend some time in the early stage to build a hiding place or survival cabin for myself, but with the storage of survival, I can give up going out to collect resources and work by myself to improve the living conditions.


    But it''s different to collect upgrade materials. After all, the resources I collected are used for upgrading. Seeing that the accommodation I built is getting better and better, it will obviously greatly satisfy the sense of achievement and participation of those players.


    Moreover, the upgrade of collected resources can also save survival, which means that the system is changing to encourage upgrading with resources.


    After all, resource upgrading needs to save survival. When collecting materials, you can save enough survival, which virtually increases the survival probability of players who upgrade with resources.


    In particular, resources can be stored in advance, as long as there are enough resources and survival, they can be upgraded.


    As for those players who directly use survival upgrade, on the one hand, the function of the Upgraded items is weaker, on the other hand, if only survival is used, their upgrade progress will undoubtedly be much slower than that of the players who use resources to upgrade.However, these may be just games for higher civilization, but for Chen Xin, they are treasures that can save lives and greatly enhance his survival probability at the end of the day.


    Thinking of this, Chen Xin also made a list to confirm what he needed.


    "One hundred kilograms of steel, five bags of cement, a set of hydroponic planting utensils and a light lamp..." Chen Xin counted the resources he needed one by one. He couldn''t help shaking his head: "there are a lot of things to be asked for. If I want to exchange these things, I''m afraid it won''t be bleeding."


    Because half of the area of Chen Xin''s greenhouse is planted with carrots that can only be matured and harvested in three months, and the yield of vegetables planted in the other half is extremely limited. Before upgrading the greenhouse, Chen Xin wanted to exchange the current vegetable yield for what he needed. He felt afraid that he would have to give up all his monthly yield.


    But it''s not too urgent. He can ask Mo Qingyan to help collect materials through uncle Ding''s relationship. First, he can use the vegetables produced this month as a deposit. Next month, when the carrots are harvested, he can settle the balance.


    With these materials, Chen Xin can upgrade the greenhouse and increase the planting area of the greenhouse four times.


    What''s more, Chen Xin uses the system to upgrade, which does not have the construction period needed for normal construction, so it can save more time.

 Chapter 48

    According to Chen Xin''s estimation, if he can get materials from Mo Qingyan this month to upgrade his greenhouse and replant vegetables in time, next month he will not only harvest vegetables seven times the current yield, but also harvest carrots planted last month, which is a bumper harvest.


    It''s just that if you really accept so many vegetables, you have to deal with them in time. Chen Xin can''t finish eating so many vegetables by himself. His only choice is to take them out for supplies.


    The big freezer he bought from Mo Qingyan would be full if he could put down hundreds of Jin of vegetables. That is to say, if his harvest in one month really increased seven times, he would have no place to put so many vegetables.


    After careful consideration, Chen Xin decided to plant upland rice according to his original idea.


    If it is to upgrade the use of materials, increase the planting area and hydroponic cultivation plate at the same time, Chen Xin can completely plant upland rice on the ground and move the planting of vegetables to hydroponic cultivation plate.


    In this way, he can not only harvest enough food for himself, but also have enough fresh vegetables to exchange for supplies.


    After all, the upgraded greenhouse will be 200 square meters in size, with the same area of hydroponic planting plate, and 200 square meters of upland rice, which can harvest two seasons a year, and can harvest nearly 600 Jin of rice.


    For the vegetables planted on the hydroponic cultivation plate, with the current planting ratio of half carrots, half cabbages and lettuce, the average monthly harvest is about 600 Jin of cabbages, 600 Jin of lettuce and 300 Jin of carrots.


    Although the carrots are harvested in March, they are more storable. Undoubtedly, they are a kind of high-quality material that can be traded.


    With such a calculation, Chen Xin suddenly found that he had a lot of goods and materials, and he had a huge surplus of rice and vegetables.


    He can exchange most of his monthly vegetable output for supplies to upgrade his shelter and make his life better. At the same time, he can also exchange other things to enrich his table, such as meat and wine.


    These outputs can also be used in exchange for other things he needs, such as small farm machinery for farming and guns for self-protection.


    Of course, Chen Xin doesn''t have to change guns. He can change vegetables for materials, upgrade the weapon cabinet, point out the gun manufacturing drawings of the weapon cabinet, and make his own guns.


    It''s just that he''s not sure what his gun will look like. If it''s more primitive, its reliability and usability will be a little worse than the one he bought.


    After all, he can find uncle Ding to change a pistol from the SWAT team through Ding Ning. If he makes his own pistol, it is likely to be the kind of simple firearms without rifling even if the upgrade level is not enough.


    That kind of gun doesn''t mean it can''t be used, but it''s not very practical, and it''s not easy to carry.


    However, the upgrade of the weapon cabinet is sure to be carried out. As the old saying goes, "the heart of harming people is indispensable, and the heart of defending people is indispensable". Having a reliable weapon for self-defense is also a guarantee for you to live better in this end of life.


    With this in mind, Chen Xin added the materials needed to upgrade the weapon cabinet to his list. He decided to take the vegetables produced this month as a deposit to contact uncle Ding with Mo Qingyan in exchange for the materials on the list. The balance would be made up after he upgraded the greenhouse and expanded the output next month.


    Although this kind of payment method is somewhat unreliable in the end, Chen Xin believes that he can still get these things in exchange for his relationship with Mo Qingyan and Ding Ning.


    After making a list, Chen Xin is ready to put up his communication antenna and connect his shortwave radio station, so that he can get in touch with Mo Qingyan and them. He doesn''t have to say anything and go to the city.


    Now the temperature is not too low, so it''s not a big problem to take a trip. But as the weather gets colder and colder, you will suffer when you go out.


    With this in mind, Chen Xin takes out the military shortwave antenna made by Lucia, which he specially prepared from the tin box, and walks out of the shelter with the box.


    Of course, the best place to set up the antenna is at the top of the mountain where his refuge is located. However, considering that the maintenance and wiring of the antenna are troublesome, Chen Xin chose to set up the antenna at the mid mountainside.


    There is a cement base made in advance. Although the fire burned it badly before, the ash and residue on the surface were swept away. The cement base on the ground is still intact, which looks dark.


    Clean up the cement base. Chen Xin takes out the shortwave antenna in the box and sets it on the cement base. He also screws the fixing bolts into the reserved screw holes to fix the shortwave antenna on the cement base.


    After installing the antenna, Chen Xin also needs to connect the antenna with the shortwave radio station in the shelter.


    Fortunately, the cable has been buried here in advance, but there is no need to pull the cable.


    Chen Xin opened the grille of the shelter vent under the cement base, pulled out a cable from it, and then plugged it into the interface under the antenna.


    After all this, Chen Xin did not forget to cover the antenna with a layer of camouflage cloth to avoid damage.Although there are few people who can still appear in the wild at this time, it must not be ordinary people. If someone finds the antenna, steals it for him or finds his refuge, and has any idea that he shouldn''t have, it will also cause trouble for him.


    So in order to reduce some unnecessary troubles, Chen Xin put a layer of camouflage cloth on the shortwave radome to make the whole antenna look like a small black mound.


    Looking at his products and patting the dust on his hands, Chen Xin went back to the shelter satisfied.


    In the shelter, Chen Xin also took out the shortwave radio, put it on the table reserved in the living room, and connected the other end of the cable to the shortwave radio.


    After turning on the switch of the radio station and adjusting the channel, Chen Xin made his first call: "this is the writer. I''m calling all the survivors here. Please answer if you hear me. We are still alive, living and prosper.


    this sentence is the signal they agreed at the beginning. When we get in touch after the disaster, we will say this sentence to show our identity and the status quo of survival.


    Chen Xin is waiting, but there is a silence in the short wave radio station. Only the faint sound of electric current flows through, which makes Chen Xin feel a little frustrated.


    Just when Chen Xin looked at the radio station which had no response and wanted to turn it off, a response voice finally sounded in the radio station: "this is the old farmer of farming land. I''m glad to hear your voice, writer. We are still alive, lively and prosper.


    "here is a drilling master. I have enough materials to accommodate my companions who need refuge. We are still alive, lively and prosper.


    "this is the Panthera Panthera. It''s in good condition. I''m glad that everyone has survived this disaster. We are still alive, live and prosper.


    "here is..."


    One by one, Chen Xin''s heart was filled with joy and excitement. All his companions in the survival group responded at the moment, proving that he was still alive.


    And the last reply also remembered at this time: "I''m long Niang, and I''ve had a good life. It''s so good that no one lost contact! Wearestillalive£¬Livelongandprosper£¡¡±

 Chapter 49

    After the disaster, to get in touch with friends again, to confirm that everyone survived the disaster, this is undoubtedly the most gratifying thing.


    Through a brief communication on the radio, Chen Xin also confirmed everyone''s current situation and learned that although everyone may have encountered some minor problems, they are basically doing well, which makes Chen Xin very happy.


    After all, everyone in this survival group is a familiar friend before. If anyone is gone because of this disaster, it is undoubtedly a unpleasant thing.


    What''s more, it''s not the peaceful environment in the past. Just after the world-class disaster, there are some people in our hearts.


    This kind of time can meet familiar people or things, for all people, although not necessarily can play a big role, but more or less can bring some spiritual comfort, let everyone in the land after this disaster more can let themselves support things.


    In the exchange of needs, Chen Xin also learned about the current situation.


    Because we had made full preparations, accumulated enough materials, and built our own shelters. Everyone in the previous survival group is now in their own shelters, successfully avoiding the previous disaster. Some group friends with good conditions even have enough to accept others.


    However, although we all survived and relatively well off, the problem is not without.


    Although most of the group friends have shelters and relatively sufficient supplies, many of them have the same problem as before, that is, lack of domestic water.


    Although we can rely on the water circulation device for a while, but in the long run, it is bound to fall into the situation of no water available.


    Chen Xin has nothing to do with this problem. Instead, the "drilling expert" in the group proposed to drill wells to solve the water supply problem.


    On the one hand, this proposal is because all the refuges are built underground, and there are difficulties in construction. On the other hand, it is also because the "drilling master" is a friend of the city, and it will not play any role for a while and a half.


    Fortunately, although there is a lack of domestic water, this problem is not serious. At present, we are living a tight life and need to pay great attention to water conservation.


    "If there is a shortage of water, well drilling can solve the problem. Even if the construction is not good indoors, well drilling can be done outdoors, and then pipes can be connected indoors. I''ve done this job, and it''s not difficult."


    In the communication channel, "drilling master" provides solutions to the water shortage shelters with his own professional knowledge, and he also says that if you need, he can bring people from Linshi to help solve the water shortage problems.


    Just waiting for him to come from Linshi is not something that can be done in a short time.


    "You''d better not come here. No one knows what''s going on on the road now. For safety''s sake, let''s try our best." Mo Qingyan heard "drilling master" said to bring people to come, immediately out of a voice to stop him.


    When the meteorite fell down before, Yanguo was not the main disaster area, but there were still a lot of meteorite debris smashed down. No one knows whether it caused road damage.


    And even if the road is smooth, if you want to come from the city, there is still a great risk.


    So after a while of discussion, it was mo Qingyan who suggested that we should provide help from this side of the city for those shelters that are short of water.


    At least she can borrow the sprinkler used for municipal greening through the special police team, and use the water tank of the sprinkler to help these shelters replenish fresh water.


    After all, we all have water circulation devices in our shelters to replenish fresh water for a long time.


    "Let''s deal with it like this first. Ah Ning and I will go to see Uncle Ding and contact the municipal government to see if we can help solve this problem." Mo Qingyan said on the communication channel that at this stage, the government is still the first choice trusted by everyone.


    In the face of disasters, the way the government has been dealing with has established a strong credibility in the hearts of the people. Even now is the end of the world, before the government collapses or loses credibility, people are still willing to believe in the government.


    After everyone finished these things, Chen Xin proposed to Mo Qingyan that he wanted to change materials.


    "How big is your greenhouse? How can we exchange so many vegetables for materials? " When Chen Xin heard that he wanted to exchange materials, it was not Mo Qingyan who was the first to speak, but a group of friends called "old farmers of farming land".


    Because he is a farmer, and also engaged in hydroponic cultivation, he knows how many crops can be produced by greenhouse cultivation.


    Because of this, he was very surprised that Chen Xin needed to exchange so many materials, because he simply estimated that Chen Xin needed at least half an acre of land to produce so many vegetables in two months.


    "I''ve dug 200 square meters for the greenhouse, but now I plan to expand it, add hydroponic planting plates, and store some materials, so that in case there is any damage to the shelter or the place needs to be expanded in the future, there won''t be no resources." Chen Xin concealed the current situation of his greenhouse, just a simple explanation.Because she had changed vegetables from Chen Xin once, Mo Qingyan also knew that he could get the promised things, so she didn''t ask much, and agreed happily: "it should be no problem. When ah Ning and I go back to find uncle Ding, we will tell him that you can provide so many vegetables, uncle Ding will surely be willing to exchange with you."


    "I''ll trouble you, long Niang." Chen Xin sincerely asks Mo Qingyan.


    "It''s a small matter. You can just give me more vegetables." Mo Qingyan quite forthright response way.


    Having said these things, Chen Xin just ended his conversation with others and turned off his radio station.


    Mo Qingyan promised to help, which undoubtedly relieved Chen Xin a lot. As long as this can be done, the upgrading speed of his refuge will undoubtedly be greatly improved.


    As long as this channel can be stabilized and vegetables can be exchanged for materials every month, Chen Xin can save a lot of survival and greatly improve the speed of upgrading the refuge.


    After all, this time he exchanged materials according to the maximum material demand given by the system.


    According to the rules of the system, as long as he can provide all the materials according to the requirements given by the system, the survival needed in the upgrade is only one tenth of the original.


    Just like the planting greenhouse that Chen Xin plans to upgrade now, if he only uses survival upgrade, the two upgrade schemes need 2000 points and 3500 points respectively to complete the upgrade.


    But now Chen Xin is able to provide all the materials required by the two upgrading schemes, and his survival point for upgrading has been reduced to 400 points, which is because he has chosen two upgrading schemes at the same time.


    The same is true for other upgrade projects. As long as Chen Xin can provide enough materials, the upgrade points can be directly cut to zero.

 Chapter 50

    However, in order to achieve all this, Chen Xin must obtain a stable material access channel to ensure that he can obtain sufficient materials, so as to meet the needs of system upgrading.


    And he has to make sure that his sanctuary has enough output to be exchanged for goods.


    Otherwise, even if there is an exchange channel, it is useless for him to exchange things.


    Under this premise, planting greenhouse has become the key to everything. Only when the output of planting greenhouse and subsequent upgrading are guaranteed, can everything Chen Xin wants go on smoothly.


    "In this case, the kitchen and weapon cabinet upgrade will be put back." Chen Xin is making a table on the computer to count the materials needed for upgrading. At the same time, he is adjusting the priority of upgrading various facilities according to his actual needs.


    At present, in Chen Xin''s revised list, the first priority for upgrading is naturally planting greenhouses. As the top priority, Chen Xin even made red remarks.


    And then there''s the generator. After all, that''s the key to the safe haven.


    However, the upgrading of generators is not particularly urgent. If Chen Xin is willing to increase the use of oil, extend the daily power generation time, or connect the second standby generator to the power system of the shelter, he still does not need to consider the problem of power system in a short time.


    Therefore, although the priority of power system upgrading is very high, it is not something that needs to be upgraded immediately.


    And then there is the weapon cabinet. After all, if you want to go out, without self-defense weapons, Chen Xin will feel insecure.


    Next to the weapon cabinet is not the necessary communication system upgrade for Chen Xin, nor the kitchen he had planned to upgrade, but the vehicle, his SUV.


    In fact, this is also a very understandable choice. SUV is a good choice as a means of transportation in peacetime. But in this end, especially when Chen Xin still needs to transport vegetables for material exchange, the vehicles that are not designed to carry goods are obviously not enough.


    This time, the materials Chen Xin exchanged with Mo Qingyan are only half of his output this month. If the greenhouse is upgraded as planned, even if the ground is used to grow upland rice and the hydroponic plate is used to grow vegetables, he can harvest 1200 Jin of vegetables and about 800 Jin of carrots after maturity.


    The total weight of so many vegetables is close to one ton. If Chen Xin only uses his own SUV to transport them, he may have to run several times to complete them. Not to mention anything else, just the consumption of gasoline is a problem that Chen Xin has to face.


    Therefore, considering the future transportation needs, it is inevitable to upgrade the vehicle or get a new truck through material exchange.


    Mo Qingyan has a pickup truck there. It was the same car that helped drag the freezer to Chen Xin''s shelter. But it''s Mo Qingyan''s car. It''s OK to borrow it, but it''s impossible to ask her to borrow it every time she has to transport vegetables?


    Although Mo Qingyan may not mind, Chen Xin still thinks it''s not good.


    As for the use of cars in the low temperature environment with lower and lower temperature in the future, Chen Xin is not very worried about it.


    Although most of the world''s auto manufacturers do not have the spare time to design cars that can be used in polar climate, the car itself can still be used normally in the environment of tens of degrees below zero.


    This point has been well proved in the north of Yan kingdom in the past. You should know that in the north of Yan Kingdom, especially in Northeast China, winter is often minus 30 or 40 degrees.


    In this weather, although the use of cars is a severe test, but the vast majority of cars can still be used normally.


    However, antifreeze is really a problem to be considered. After all, cars can stand it, but people may not also stand it. The low temperature of tens of degrees below zero can really freeze people to death.


    After recording these thoughts on this schedule, Chen Xin turned off his computer, felt his hungry stomach and was ready to get himself something to eat.


    Thanks to vegetables, Chen Xin got his first harvest. Now he has a lot of food. At least he doesn''t need to eat a bag of self heating food every day. Instead, he can eat it with vegetables and canned luncheon meat. He can also occasionally add a meal to his own to have canned pork.


    The abundance of food not only increases the total amount of energy Chen Xin consumes every day, but also makes his nutrition more balanced and rich, so as to avoid the possibility of malnutrition due to lack of food.


    Come to the "kitchen" in the living room. Because the kitchen has been removed from the priority of the upgrade plan, Chen Xin''s current "kitchen" is just an induction cooker and a set of cookware used by Chen Xin outdoors.


    Of course, in addition to this, there is a simple chopping board and a fruit knife that can be used to cut vegetables. These are the cookers that Chen Xin used when he went to participate in outdoor sports or survive in the wild.


    Originally, there was a folding gas stove, but that thing needed to be connected with an additional gas tank. In this end of the world situation, Chen Xin felt that the tank of liquefied gas he had stored was better reserved for use at a critical time.Before the vegetable harvest, Chen Xin could only eat self heating food every day, so he only used a small pot which could be used as a frying pan or a lunch box.


    Now with vegetables and cans, Chen Xin can at least add fried cabbage or lettuce to his meal, or fried lunch meat and fried lunch meat with vegetables.


    As for canned pork, considering that it will be difficult to eat them after they are finished, Chen Xin does not eat every meal extravagantly. Instead, he plans to open one a week to save as much as possible.


    After all, pork is likely to be hard to eat in the future. Instead, it''s canned luncheon meat. If you don''t mind eating luncheon meat with cockroaches or mice as raw materials, Chen Xin believes that he should still eat it frequently in the future.


    With this in mind, Chen Xin also tore up the self heating food packaging bag, added a little water to it, and put it aside. Soon, the heating bag in the packaging bag reacted with water and released heat.


    At this time, Chen Xin took out half of the lunch meat that he had not finished in the morning, sliced it on the cutting board, and then put a frying pan on the induction cooker. After the pan was hot and the oil was poured, he put in the sliced lunch meat and began to fry it.


    A smell of meat diffuses with the sound of Zizi. Chen Xin, who hasn''t smelled the smell of meat for a month, can''t help shaking his fingers.

 Chapter 51

    Eating as usual, but today Chen Xin opened an extra can of pork for himself to improve his food.


    While eating, he was chatting with Mo Qingyan on the short wave radio, talking about materials.


    After a month''s collection, Mo Qingyan has obtained all the materials Chen Xin needs through uncle Ding''s relationship, and uncle Ding has agreed to Chen Xin''s terms of payment by installments. These materials have now been sent to Mo Qingyan.


    "Ingredients, shall I deliver them to you tomorrow, or will you come and get them yourself?" Mo Qingyan seems to be eating there. Even across the radio station, Chen Xin can hear Mo Qingxin shouting and Ding Ning grabbing food there.


    However, this did not interfere with Chen Xin''s thinking. Without much thinking, he replied, "you can help me transport it. My car can''t tow so many things. By the way, you can also tow the vegetables of this month."


    Mo Qingyan didn''t feel strange about Chen Xin''s choice, so she agreed happily.


    "It''s hard for you to get these materials so quickly. Thank you, long Niang." Chen Xin is very grateful for Mo Qingyan''s help. Although they really have a good relationship, they still have to say thank you.


    "It''s obvious to say that, and this batch of materials are mainly made by Uncle Ding. I just want to pass on a message for you." Mo Qingyan is as straightforward as usual, but she also reminds Chen Xin: "although uncle Ding promised you to make up all the supplies next month, he also asked someone to come to you to have a look, saying that he wanted to make sure that you could pay for so many supplies Xin, what do you think of this? "


    "What do you think? What can I think? If you''re not sitting or standing, can you still lie down and see? " Chen Xin has a poor mouth, is joking at the same time, but also understood the meaning of Mo Qingyan''s words, vigilant.


    Uncle Ding said that he would send someone to have a look. Maybe it''s just like what he said to confirm whether Chen Xin is able to pay the bill, but what if someone wants to see the money?


    Chen Xin and Mo Qingyan are good friends. They have a very close relationship. They have enough trust in Chen Xin. Ding Ning is also an acquaintance of Chen Xin. They have been living in the wild for several times, and their relationship has always been good. That''s why Chen Xin asked them to come to their refuge last time.


    But for uncle Ding, Chen Xin has only dealt with Ding Ning several times just because he is his father. He only knows his surname is Ding and is the captain of the city special police force.


    In addition, Chen Xin didn''t even know his full name. He just called him uncle Ding all the time.


    Maybe the captain of Tangtang special police team doesn''t care about Chen Xin, but what about others?


    What Chen Xin owns is a shelter with complete facilities and self-sufficiency, which is enough to make people envious.


    The reason why people can''t commit a crime is that most people can restrain themselves because of their noble morality. Most people are deterred by the law, which makes them know that the cost of crime is very high and fear the punishment that crime may bring.


    This is also the meaning of the law established by the state. It is not to punish you after you commit a crime, but to deter you before you commit a crime, so that you do not dare to commit a crime.


    However, with the advent of the end, after the collapse of the old social order, the original perfect supervision system has disappeared, the cost of crime has plummeted, and the crime rate is also growing.


    The person Mo Qingyan met before who wanted to have a wrong idea of her is enough to show that the dark side of people''s heart is growing in the present eschatological environment.


    Thinking of this, Chen Xin asked the shortwave radio station, "what do the people sent by Uncle Ding want to see?"


    "What else can I see? The old boss is afraid that I will be cheated. A little material is a small matter, but if I am cheated by his baby daughter, can you believe that he can turn over the whole city?" The reply is Ding Ning. She seems to be very dissatisfied with her own Laozi, but she is a little proud.


    Chen Xin shakes his head. He probably understands Ding Ning''s meaning. She thinks that uncle Ding just wants to send someone to check whether Chen Xin has the ability to pay the bill, or is cheating resources through Ding Ning, so there are some bad plans.


    This kind of worry is human, but for Chen Xin, it reminds him that we must pay attention to the protection of the refuge.


    After thinking for a while, he asked Ding Ning, "who is your father going to send? The man under his hand? I have nothing to look at. Didn''t you two come to see it last time? You don''t have to let people see it again? I don''t want strangers to know where my refuge is


    "Don''t worry. I told my dad about it. You know the people he sent." Ding Ning tone a few more silk smile, obviously understand what Chen Xin is worried about: "Lan elder sister you always know? Are you still worried that she will harm you? "


    "Qin LAN? Your father asked her to come? " Chen Xin was surprised and embarrassed. It was obvious that the man sent by Uncle Ding was beyond his expectation.


    Qin LAN is one of the few female special police officers in the city''s special police team. She is not a civilian who sits in an office, but a real special police member who acts as a sniper.As a female special police officer who is a rare species in the police system, and Qin LAN herself is not bad, she naturally becomes a police flower of the city police station, with many pursuers.


    However, Qin LAN did not have the idea of looking for an object in the police system, but under the introduction of Ding Ning, she once had an association with Chen Xin for a period of time.


    "What''s the matter? You''ve been breaking up for a long time. Sister LAN doesn''t care about it. " At the beginning, Chen Xin knew Qin LAN through Ding Ning''s introduction, so she naturally knew the things between them very well: "and you have a better relationship with sister LAN in the whole SWAT team, can you trust other people?"


    Ding Ning''s words made Chen Xin speechless.


    He broke up with Qin LAN at the beginning just because they had different personalities. There was no right or wrong between them. But now that they have become predecessors, the relationship will be more or less embarrassing.


    Just as Ding Ning said, other members of the SWAT team didn''t have a good relationship with him.


    As for the reason, it''s Qin LAN. After all, Qin LAN is chased by many people in the SWAT team.


    "Well, when are you coming tomorrow?" Chen Xin has no choice but to acquiesce in this matter at this time. After all, if Qin LAN comes, he can rest assured.


    "In the morning, let''s go over after breakfast." Mo Qingyan replied to Chen Xin and set the time.

 Chapter 52

    The next morning, with the alarm of the mobile phone, Chen Xin got up from bed.


    He brushes his teeth, washes his face, and shaves with a razor he hasn''t seen for a long time. Looking at himself cleaned up in the mirror, Chen Xin feels his freshly shaved chin, and his face is inexplicable.


    He didn''t know why he had to deal with himself like this. Normally, it was the end of the world. Chen Xin, who didn''t need to go out to meet people, didn''t even shave.


    But he set the alarm clock half an hour earlier last night, so that when he got up early, he cleaned himself up, just like when he was going on a date with Qin LAN.


    Thinking of this, Chen Xin couldn''t help holding his face down.


    This has become a natural habit. Every time I meet Qin LAN, Chen Xin will clean up himself.


    After all, Qin LAN is a beautiful woman. If Chen Xinli goes to see her, he will feel inappropriate.


    Thinking about these things in his mind, Chen Xin finished his breakfast as usual.


    Through the radio station to confirm that Mo Qingyan and Chen Xin have set out, Chen Xin just goes to the greenhouse and wants to collect the vegetables in the field before they come.


    The crops in the greenhouse are all mature. Under the careful care of Chen Xin, both cabbage and lettuce grow very well.


    In fact, even the carrots that have been planted nearby for two months can be harvested, but what is harvested is nothing more than a thumb thick thing. Although it can be eaten, it will lose a lot in yield, so Chen Xin decided to wait until next month to harvest.


    To harvest cabbage and lettuce, it is not necessary to pull the whole plant out of the field, which is not only easy to damage the crops, but also inefficient, and easy to make a mess of the original regular fields.


    The correct harvesting method should be to cut the roots of cabbage and lettuce with sickle, which can not only maximize the harvest of mature crops, but also save time and labor, and can be harvested quickly.


    However, novice Chen doesn''t have a sickle. He takes a long dagger from the weapon cabinet. This is a multi-functional dagger that he used to use when he was living in the wild. Although it''s not so suitable, it can make do without tools.


    Fortunately, Chen Xin had already collected vegetables once last month, and he had accumulated some experience. In addition, the field was not big, so he quickly cut all the cabbages.


    Just as Chen Xinzheng piled the cabbages together for packing later, he heard the radio in the living room ring.


    Because he was afraid that he would not hear Mo Qingyan''s call when he was collecting vegetables in the greenhouse, Chen Xin turned on the radio to the maximum today to ensure that he could hear the radio even in the greenhouse.


    After a simple wipe, Chen Xin went back to the living room and sat in front of the radio station.


    "Ingredients, ingredients! This is long Niang. Please answer if you hear me! If you hear me, please answer In the radio station, Mo Qingyan is calling. She shouts loudly, but Chen Xin turns up the volume, which makes Mo Qingyan''s voice very loud.


    Chen Xin quickly turned down the voice of the radio station. Then he rubbed his ears and replied, "yes, why are you roaring so loud?"


    "I''m at your door. Open the door quickly!" Mo Qingyan heard Chen Xin''s reply, although she lowered the volume, she was still urging Chen Xin.


    "I know. I know. I''m driving. I''m driving." With that, Chen Xin walked towards the gate of the shelter and opened the two gates of his own shelter.


    Outside the gate, a truck is parked at the door, full of Chen Xinyao''s materials. Mo Qingyan sees Chen Xin come out, has put down the window, and is greeting him.


    Chen Xin also smiles at Mo Qingyan, but his eyes unconsciously turn to the figure who is in charge of driving. This is the first time he meets Qin LAN after they break up.


    But no matter Chen Xin or Qin LAN in the car, there is no more expression.


    "Ingredients, can you drive in?" Mo Qingyan opens the door and jumps out of the car. As she asks Chen Xin, she also looks at the gate of the shelter behind him.


    Chen Xin looked back at his front door, then at Mo Qingyan''s car. He shook his head and said, "I''m afraid you can''t get in. Last time you drove a pickup truck, it''s smaller. Fortunately, the front of this truck is too high. I''m afraid it will get stuck."


    "Well, I expected that before I came." Mo Qingyan didn''t seem to be surprised. She nodded and walked toward the back of the car: "come and help unload the car!"


    Chen Xin walked over, and Mo Qingyan climbed directly into the car, pulled out a small cart from the car, and said to Chen Xin with pride, "fortunately I brought this, otherwise it''s really hard to move things."


    Seeing Mo Qingyan take out the cart, Chen Xin realizes that he has too many goods and materials, and the car can''t drive into his refuge. If there is no cart to transport, he won''t have to move by hand for a day.


    "It''s still long Niang. You think it''s thoughtful." Chen Xin praised Mo Qingyan and took the things she had taken from the car and put them on the cart.And at this time listen to the car Qin Lan also came over, want to help handle, move things together.


    When seeing Chen Xin, Qin Lan also said hello to him: "long time no see, ah Xin."


    "Ah lan..." Chen Xin sees Qin LAN and wants to say hello to her. However, one of them doesn''t notice. He almost doesn''t catch the cement bag that Mo Qingyan handed him from the car. Qin LAN reaches out to help, but doesn''t let the cement bag hit Chen Yu''s feet directly.


    "You still lack exercise as before." While talking about Chen Xin, Qin LAN easily put the bag of cement that Chen Xin almost didn''t hold onto the cart.


    Looking at Qin LAN relaxed appearance, Chen Xin embarrassed let to one side, said to her: "just did not take steady, and I rely on the brain to eat, how can and you compare."


    With that, Chen Xin reflected that this sentence was exactly what he said before they broke up and when they quarreled.


    "Ah Xin, your character has not changed! It''s the same as before. " Qin LAN smiles at Chen Xin, reaches out her hand and takes a bag of cement from Mo Qingyan''s hand and puts it on the cart. Then she says to Chen Xin, "it didn''t matter before, but now in this kind of environment, it''s better for you to exercise, even if it''s not for..."


    Speaking of this, Qin LAN can''t help but pause. She still likes to persuade Chen Xin to get rid of some bad habits as before, but now they are no longer friends and girlfriends. It''s not appropriate to say that again.


    Chen Xin didn''t feel anything at this time. He just nodded to Qin LAN and agreed: "it''s time to exercise, or you''ll be tired to death just by farming."

 Chapter 53

    With the help of Qin LAN and Mo Qingyan, Chen Xin quickly moved all the materials they had brought to his shelter and stored them in the storeroom.


    Because there are too many materials, the whole storage room is so full that some of them can only be put in the garage and piled next to Chen Xin''s SUV.


    "I said," ingredients, why do you exchange so many materials? Most of them are building materials. " Mo Qingyan takes off her gloves and pats the dust on her body because of carrying materials. Looking at the piles of things in front of her, she can''t help but wonder why Chen Xin has to change so many materials: "even if you want to expand the greenhouse, you can''t use so many things, can you?"


    One side of Qin LAN heard Mo Qingyan asked this question, she is also very curious to see Chen Xin, very want to know why he changed so many materials.


    "I''m not trying to rebuild the shelter before the temperature drops below zero!" Chen Xin hit a ha ha, although did not lie, but also did not reveal the truth.


    In fact, so many materials were used to expand the greenhouse, but Chen Xin obviously added a lot of surplus when exchanging materials.


    Now that the disaster is just around the corner, it''s relatively easy to collect materials. If we don''t reserve more materials now, it''s not easy to collect materials when the situation gets worse.


    "Transforming the sanctuary? You alone? Is that ok? Do you need me and Anning to come and help? " Mo Qingyan is surprised when she hears that Chen Xin wants to rebuild the shelter. She doesn''t remember how Chen Xin knows how to build the shelter.


    In the face of Mo Qingyan''s initiative to help, Chen Xin, although very grateful for her willingness to help at this time, still shook his head and refused: "no, the project is not large, I have no problem alone. There''s nothing to do in the shelter, just pass the time. "


    Of course, it''s impossible for Chen Xin to ask Mo Qingyan to help. Otherwise, when someone comes, he finds that he has nothing to do. Chen Xin can''t explain.


    "And I don''t have a place to live here. If you come here to help, you can only go back and forth every day. That''s too much trouble, isn''t it?" It seems that in order to distract Mo Qingyan''s attention, Chen Xin also deliberately said: "and now in this situation, do you need to reinforce your own shelter?"


    "That''s true. I''m running to you every day, and you have to control your food and control your life..." Mo Qingyan thinks about it for a while, and thinks it''s too troublesome to do so. Moreover, she thinks Chen Xin''s suggestion is very reasonable: "if I''m at home, it seems that I really need to repair the wall, and the front door of the store on the first floor should be sealed."


    As for Mo Qingyan''s idea, Chen Xin quickly suggested: "what you should reinforce most is the gate in your yard. There was no problem with the iron gate in the past, but now it can be knocked open by car collision, so you''d better reinforce it."


    After Chen Xin said this, Mo Qingyan reflected that her refuge really had many loopholes.


    "I know, then according to ah Xin, I''ll go back and transform the shelter well." Mo Qingyan obviously listened to Chen Xin''s suggestion and decided to go back and rebuild her shelter.


    After hearing Chen Xin and Mo Qingyan discuss the transformation of the refuge, Qin LAN is obviously a little out of the way on this topic. She is living in the collective refuge of the city police station, unlike the two people who live in their own private shelters.


    However, Qin Lan also reminded Mo Qingyan: "in fact, the three floors of your house can also be used. Now, although the temperature has dropped, the ground is not suitable for people to live on, but on the other hand, can''t low temperature be used to store materials?"


    "That makes sense! The surface temperature will be dozens of degrees below zero. Isn''t this a natural refrigerator? As long as you are not afraid of the cold, you can put it up, right Mo Qingyan was also reminded by Qin Lan''s idea. She patted her thigh happily, showing some excitement: "in this way, my original warehouse can still make some space, and I don''t have to rush to empty the wine cellar."


    Hearing Mo Qingyan mention wine cellar, Chen Xin immediately thinks of her wine collection.


    Mo Qingyan''s bar only serves members, so the wine she prepares is really good wine, many of which can be regarded as treasures.


    Although Mo Qingyan prepared these wines for the bar, the treasures are not always available. Even if Chen Xin and Mo Qingyan have a good relationship, they can only be drunk once in a while.


    Thinking of this, Chen Xin advised Mo Qingyan, "I think you can change the wine cellar into a greenhouse. Although you can''t grow vegetables and rice as I do here, you can also get some mushrooms or hydroponic vegetables."


    "Turn the wine cellar into a greenhouse and grow some mushrooms?" After hearing Chen Xin''s proposal, Mo Qingyan seriously considered the feasibility of doing so: "but in that case, there will be no place for my wine."


    "Your wine To tell you the truth, they are all good things that can''t be regenerated in the last days. It''s reasonable to keep them well. " Chen Xin was worried about the wine, so he quickly said: "but the key now is to fill your stomach first. Long Niang, your refuge has no self-supporting ability, and it depends on your stored materials. But how long can these materials last? If you don''t think about it now, it will be very dangerous in the future. "Chen Xin''s words make Mo Qingyan fall into thinking. She really needs to consider what to do after she finishes her reserve.


    Just for mushroom cultivation, Mo Qingyan has no idea. She doesn''t know how to start in this situation.


    "As for your wine, don''t waste it. Why don''t you give it to me?" Chen Xin is very concerned about the good wines collected by Mo Qingyan.


    "So you miss my wine! I said, "why did you encourage me to turn the wine cellar into a greenhouse?" When Mo Qingyan heard Chen Xin say this, she just pursed her lips and thought about it for a moment, then said, "it''s OK to change another batch of wine for you. I was going to empty the wine cellar, and make room for storing materials.


    Now that we can use the floor on the ground to store materials, it''s not impossible to change the wine cellar into a greenhouse, but I don''t know how to grow mushrooms. Even if we change the wine cellar into a greenhouse, it may not be of any use! "


    "In this case, the police station has a complete set of mushroom cultivation technical manual, which was prepared by the state for each refuge before. I can copy it to you later, and I can sell you some mushroom bags." Qin LAN is a great help to Mo Qingyan at this time.


    Hearing Qin LAN say that she can provide technical support for herself, Mo Qingyan is very happy and says thank you to Qin LAN.

 Chapter 54

    In fact, Mo Qingyan also knows how important it is to have a greenhouse that can produce food in the end of the world. However, the shelter of her family was built when the house was built. At that time, she did not consider the greenhouse. Instead, she designed the basement as a bar.


    As a result, Mo Qingyan''s shelter has no self-supporting ability in food.


    In the short term, of course, this is not a problem. Whether it''s exchanging goods with others or getting food in other ways, it can be sustained.


    Even because there is enough underground space, Mo Qingyan has a lot of materials in reserve, enough for her, Mo Qingxin and Ding Ning to eat for two years.


    If it''s just a nuclear war or other doomsday disaster, one or two years is enough time for them to wait for reconstruction or rescue teams.


    But now we have to face a century long cold night. The earth''s surface will be frozen for 100 years, which is not suitable for any crops. Almost 99% of human food production has been completely wiped out.


    In this case, all one can count on is the reserves of supplies before the disaster, and the underground, less temperature affected greenhouses built in shelters.


    Chen Xin may not know the situation because she is far away from the city, but Mo Qingyan knows something about the situation because she is close to the city''s Government shelters and shopping center shelters. Now the shelters in the city have begun to control the use of materials.


    Although the main source of food is the pre disaster grain reserves, it has also begun to match the food with the mushroom produced in the greenhouse and the mice raised.


    In Yanguo, mushroom cultivation technology has been quite mature, which is why the government chose mushrooms as the main food source for post disaster shelters.


    Mushroom is the main food source available in the current environment. If the management is reasonable and the planting area of 100 square meters adopts three-dimensional cultivation with five layers, the yield of even the most conservative output of 30 jin per square meter can reach 75000 Jin per year.


    The yield is not low, but if they want to ensure the food supply of a shelter, although it is difficult to build a greenhouse in a small shelter, they don''t need too much planting area to ensure the food supply.


    It''s like Chen Xin''s shelter, a 100 square meter greenhouse for planting mushrooms. If all kinds of mushrooms are used, Chen Xin will be able to eat enough to survive. There is still surplus production to be used to make mushroom wine and drown himself.


    But for the big shelter, the problem is more serious, and the bigger the shelter, the more serious the problem.


    Because the more people there are, the more food they need, and the larger the greenhouse area they need.


    After all, at first glance, one hundred square meters can produce more than 70000 Jin of food a year. However, the city has a resident population of 300000. Thanks to the policy of "not abandoning one person" of the government before the disaster, at least 90% of the people have been able to enter the refuge and survived.


    According to one ton of food consumed by one person a year, 270000 people need at least 360000 square meters of mushroom planting area to meet the consumption.


    Because no crops can be planted on the surface, all the food sources are underground greenhouses, but there is obviously no such large space for planting greenhouses in the shelter.


    And 360000 square meters is 3600 mu, 540 Mu and 36 hectares, which is equivalent to half of the Forbidden City, 1.7 bird''s nests and 51.4 standard football fields.


    Such a large area, if it is before the disaster, of course, is nothing, not counting the area of rural cultivated land, just the labor reform farms near the city have 36500 mu of cultivated land, food output is not a problem at all.


    As for those who want to build greenhouses, if they want to build them on the surface before the disaster, such a large area of greenhouses is nothing more than a matter of money, and there will be no construction difficulties.


    But at the end of the disaster, because of the severe cold, it is impossible to build a greenhouse on the surface. If we want to ensure enough food output, we can only dig out enough space underground.


    It takes a long time to dig out such a large area of underground space.


    Even if all the major shelters have enough manpower, they may have enough tools in reserve before the disaster. It is a very big project to dig out such a large space.


    In other words, in the future, if there are no other factors, food shortage will be an inevitable problem for the major refuges.


    Fortunately, the end of the world has just begun, and the major refuges have sufficient material reserves, which can last for a long time.


    This period of time is a golden time for all shelters. Whether they can cope with the food crisis depends on whether they can dig up enough greenhouses during this period of time.


    Therefore, it can be predicted that in the future, food will become the most urgent demand, and ensuring a stable food supply will become the top priority to survive in this end of life.


    Whether it''s Chen Xin or Mo Qingyan, or people in other shelters, if they want to survive in this last world, they must first solve this problem.Fortunately for Chen Xin, with systematic help, food is no longer a problem for him.


    "Well, with Alain''s help, the problem of long Niang is solved." Chen Xin looked at Mo Qingyan and said to her with a smile in his voice, "then you just need to empty the wine cellar and transform it into a greenhouse."


    "Well, if I empty the wine cellar, you can think about my collection, right? I tell you, if you want my wine, you can exchange it for something good! " Mo Qingyan snorts at Chen Xin.


    Looking at Mo Qingyan''s picture, Chen Xin immediately smiles: "don''t worry, I''m sure I won''t let you down!"


    Qin LAN just watched the quarrel between Chen Xin and Mo Qingyan. When they finished talking, she said, "if you''ve finished talking, is it time to get the dishes you promised to our SWAT team?"


    Although Chen Xin exchanges materials with Uncle Ding in the name of Mo Qingyan, both uncle Ding and Chen Xin understand that the two sides of the transaction are Chen Xin himself and the special police team.


    After all, although uncle Ding is the captain of the special police team, he can''t get so many materials himself, and he can''t take so many vegetables to eat alone. Therefore, it''s inevitable to collect materials in the name of the special police team and exchange vegetables to improve the food for the special police team.


    So it''s not a problem for Qin LAN to say that.


    In the face of Qin Lan''s urging, Chen Xin smiles and takes them to his greenhouse: "don''t worry, the dishes are ripe. I was harvesting before you came."

 Chapter 55

    With the help of Mo Qingyan and Qin LAN, Chen Xin''s 600 Jin vegetable harvest this month was quickly collected from the field and put in the box Qin LAN brought to their car.


    "Let''s go first, Xin. Take care of yourself." At the gate of Chen Xin''s shelter, Qin LAN looks at Chen Xin and says something to him, but feels it''s hard to say.


    "Well, Alan, you are the same. Now this kind of environment is no more dangerous than before. Now you should pay more attention to safety." Chen Xin see Qin LAN care about themselves, or very careful, also told her some.


    Qin LAN nodded. She was ready to leave without saying anything more. Just when she came out of the gate of the shelter, she looked back and frowned and said, "Xin, you should reinforce the gate of the shelter, and you should make some camouflage outside. As you said, now the environment is no longer better than before, you Pay more attention to safety. "


    "I see. I''ll deal with it later." Chen Xin nodded, Qin Lan said the problem he has actually considered, but not included in the top priority.


    See Chen Xin listen to his words, Qin Lan also nodded, this just got on the car, start the car ready to leave.


    "Ingredients, when you harvest carrots next month, remember to leave some for me. I''ll trade Lafite with you!" When she leaves, Mo Qingyan still sticks her head out of the window and places an order with Chen Xin.


    "I see!" Chen Xin responded and watched them go away. Then he turned back to the shelter and closed the door again.


    Back inside the shelter, Chen Xin couldn''t restrain his excitement and ran directly into the greenhouse to upgrade it.


    "Simple planting greenhouse"


    "upgrade scheme 1: increase drip irrigation system, increase hydroponic planting plate, crop yield + 10%, irrigation water consumption - 10%, upgrade survival points 2000"


    "upgrade scheme 2: increase planting area, improve lighting efficiency, crop yield + 10%, lighting time - 10%, upgrade survival points 3500"


    "do you provide Steel, cement, fill light lamp, micro vacuum pump, PVC pipe, PVC hydroponic planting plate and other materials will be upgraded


    "Scheme 1 materials have been provided, and the survival points required for upgrading are reduced by 90% and 200 points"


    "scheme 2 materials have been provided, and the survival points required for upgrading are reduced by 90% and 350 points"


    "scheme 1 and scheme 2 upgrade materials are met at the same time, and the survival points required for upgrading are reduced by 150 points and 400 points, do you want to upgrade?"


    In the face of the system to brush out the text, Chen Xin no doubt chose to upgrade, and this will also be his hand only 400 survival points are all used up.


    With Chen Xin''s choice to upgrade, the whole greenhouse is also shrouded in the light of the upgrade Chen Xin has seen twice.


    And this time, not only the greenhouse, Chen Xin placed in the storage room and garage of various materials are also covered by light, and become light points gathered in the greenhouse.


    When the upgraded light in the greenhouse dissipated, Chen Xin was presented with a double enlarged area and a layer of hydroponic planting plate hanging from the ceiling, which made it look much more advanced than before.


    The increase of planting area and the emergence of hydroponic planting plate are very intuitive changes, but it is a more subjective feeling that the greenhouse has become more advanced.


    After all, in the absence of upgrading the level of science and technology, to distinguish whether something is advanced or backward depends largely on people''s subjective judgment.


    But looking at the clean and tidy after the upgrade, which has been upgraded from the headlight to the fill light of the lamp tube, the light is soft and bright, the field is standard and tidy, even the crooked carrots planted before Chen Xin are re planned into a straight line of planting greenhouse, Chen Xin really feels a kind of advanced "fan".


    The greenhouse in front of us no longer looks like the ordinary shelter greenhouse that Chen Xin used to build, but more like a plant growing laboratory.


    But even so, the greenhouse is still used to grow crops and get food.


    So no matter how good it looks, for Chen Xin, the key is to make the upgraded greenhouse easy to use.


    Originally, the ground of Chen Xin''s greenhouse was directly soil. Previously, it was Chen Xin''s own ridge that was used to divide the land. There was no planning.


    But now 200 square meters of planting area, the land has been evenly divided into eight rectangular pieces of land, it seems a lot more regular.


    Standing between the ridges of the field, Chen Xin reaches out his hand and grabs a handful of soil from the ground. He rubs it with his hand to check the soil.


    It seems that even the soil has been affected by the upgrading, and these soils also seem to have been upgraded.


    Originally, the soil in Chen Xin''s greenhouse was obtained by him from the nearby farmers'' vegetable garden. It is ripe soil and has been carefully managed. It is suitable for crop cultivation.


    However, compared with the soil in the current greenhouse, the former soil is obviously grayer, and the contrast is quite obvious.Now the soil in the greenhouse is dark and shiny. The soil is fine and fluffy. When you pinch it with your hand, you even feel like you want to squeeze out oil, which makes you feel fertile.


    Although Chen Xin didn''t know much about the soil, he could probably guess that it was the most fertile black soil in the north of Yan country.


    This is much better than the soil he used before. This natural treasure given by nature is very suitable for planting crops. The whole Bluestar even has only three black lands.


    The changes in the soil gave Chen Xin a deeper understanding of the power of system upgrading. He did not expect that upgrading the greenhouse could upgrade the soil together, or upgrade it to this kind of black soil which is most suitable for crop growth.


    In addition to the change of soil quality, the most obvious change in the greenhouse is of course the hydroponic planting plate hanging from the ceiling.


    Among the materials exchanged by Chen Xin before, there was a set of hydroponic planting equipment, including hydroponic planting tray, nutrient solution circulation pipeline and micro vacuum pump. However, the equipment exchanged by Chen Xin was obviously inferior to the same type of equipment provided after the system upgrade.


    Although the hydroponic planting plate is called a plate, it is actually not a plate, but is composed of nutrient tank and planting plate.


    Chen Xin''s hydroponic tray is a very common plastic tray, and the planting board is a grid shaped board. It looks ordinary and feels rough to the touch.


    However, after the system upgrade, the tray has become an integrated sink, and the planting board has become a more professional planting board with one slot after another. In particular, the color has been changed to white by the system, and the feel is smooth and mellow, so it looks very clean.


    The bracket is also provided with a pipe for circulating nutrient solution and a light supplement lamp for providing light for the lower layer plants, so that the light of the lower layer crops will not be affected by the shelter of the hydroponic planting plate.


    Chen Xin reached out to hold the bracket hanging from the ceiling and tried to shake it. However, he found that the bracket was quite stable without any shaking. It seems that the quality of things after the system upgrade is also quite good.


    After checking the upgraded greenhouse, Chen Xin also began to prepare for the use of hydroponic planting system. Although hydroponic planting is hydroponic, it is not really just water.


    Although it is said that only water crops can grow, they can''t grow well and harvest naturally.


    Therefore, in the normal circumstances of hydroponic cultivation, it is necessary to add the formulated nutrient solution into the water to provide various trace elements needed for crop growth.


    Chen Xin naturally knows this, so when he asked Mo Qingyan to exchange materials for him, he not only got a set of equipment for hydroponic cultivation, but also a large bottle of concentrated nutrient solution.


    This nutrient solution is a general nutrient solution for plant cultivation, and it is a highly concentrated model. According to the instructions on the package, only 30 ml is needed to produce four liters of nutrient solution.


    The capacity of this bottle of highly concentrated nutrient solution is 1.8 liters. According to the area of Chen Xin''s current greenhouse, this bottle is enough for him to use for several years.


    After checking everything, Chen Xin was very satisfied with the greenhouse after the system was upgraded. After mixing the nutrient solution, he began to prepare for breeding.


    Hydroponic planting is different from soil planting. In soil planting, seeds can be directly sown into the soil, and the crops will germinate, take root and grow.


    But for hydroponic planting, even if there is a planting plate, breeding should be carried out in advance. Only when the roots and leaves grow out can they be moved to the nutrient tank for planting.


    Fortunately, Chinese cabbage and lettuce are the two new species. The breeding of these two crops is not complicated. Just take down the planting board, put seeds on the sponge used to fix the plants in each slot, and then water and mix the nutrient solution to keep the sponge moist, so that the seeds can germinate.


    When taking down the planting plate from the support, Chen Xin also noticed that there were still some problems with the installation height of the hydroponic planting plate.


    The ceiling of Chen Xin''s greenhouse is two meters and five meters high. Although it feels a little low, there was no problem when Chen Xin used it before.


    However, after the upgrade, there were more hydroponic plates. The height of hydroponic plates was about 1.5 meters above the ground, which led to Chen Xin''s inability to straighten up when taking care of the lower crops on the ground.


    Although farming is definitely bent down, if you can''t straighten up all the time, you will still feel very uncomfortable. After all, even when the farmer''s uncle plows the land, he sometimes straightens up to have a rest and won''t bend all the time.


    Fortunately, Chen Xin''s greenhouse is not big, and the land to be planted is only 200 square meters, so it won''t be too tired.


    Just aware of this problem, Chen Xin thought of the small agricultural machinery he had prepared to make before.


    This time, the materials exchanged with Uncle Ding did not include small agricultural machinery. It''s not that Chen Xin didn''t mention it, but that uncle Ding didn''t send the small agricultural machinery he wanted together. Instead, he said that he would wait until Chen Xin paid off the balance of the transaction next time.


    Obviously, uncle Ding is still wary of Chen Xin.It''s not about trust. Even before the disaster, it''s normal to ask a bank loan or a friend what kind of mortgage they need to borrow money from. Chen Xin''s installment payment makes the other party feel a little uneasy, so it''s normal to keep one hand.


    Chen Xin doesn''t have any dissatisfaction or opinions about this, but in this way, his work this month will be harder.


    Fortunately, when the system was upgraded, the soil on the ground was also upgraded. Instead of fertilizing and plowing the land, he just needed to sow the seeds of upland rice.


    It''s evening to finish the work of planting greenhouse.


    Although there is no change in the light, the night can not be called the night, but the work and rest time is still the same.


    After dinner, Chen Xin collapsed on the sofa in the living room, playing with the game machine.


    After a whole day''s hard work, Chen Xin feels that his muscles are aching. Although he has done a lot of farm work in the past month, he still feels very tired today, so he wants to play two games to relax.


    It''s normal to feel tired today. After all, we moved all kinds of materials in the morning, hydroponic breeding and upland rice sowing in the afternoon. Compared with the previous month, the workload has increased a lot.


    Fortunately, there is no need to plough today, otherwise Chen Xin feels that he is going to break his waist.


    While rubbing the handle, Chen Xin took a sip of the cup beside him. He couldn''t help smacking the pale boiled water in his mouth. At this time, it would be nice to have a bottle of feizhai happy water.


    Unfortunately, there is no fat house happy water in the refuge, which is a holy thing to eliminate fatigue. Some of it is only tasteless pure water.


    Before the disaster, Chen Xin mainly collected materials for survival. Although materials like happy water in fat house could not be collected, Chen Xin did not think about them at that time, so that when he could not drink now, he would think that he was not prepared at all.


    Now that the disaster has come, it may be possible to get happy water through material exchange. I just don''t know if there is any stock in the large shelter.


    After all, it belongs to consumables. Now after the disaster, I''m afraid that even if the country organizes to resume production, it will not waste resources to produce these non survival materials. Instead, it will use all resources to produce survival materials.


    Thinking of this, Chen Xin can''t help sighing. Not only happy water in fat house, but also familiar things will disappear with the disaster and become a record in the history book.


    I don''t know whether human beings can produce these things again after resuming production and rebuilding their homes. How many things of the past can be restored?


    Chen Xin doesn''t know the answer, but he sincerely hopes that if possible, he can restore his former life, even if it is only part of it.

 Chapter 56

    While Chen Xin is still busy upgrading the greenhouse and planting seeds, Qin LAN returns Mo Qingyan to the police station in a truck after returning her home.


    The gate of the original city police station is free to go in and out, because the city''s exit and entry management hall is in the office building of the city police station, where people usually come to handle the relevant procedures.


    This is also the city''s telephone alarm center, so the city police station has been very busy no matter day or night.


    But now, not only have the railings been put down, but also roadblocks have been set up outside the gate, which can be used to get in and out at will.


    Qin LAN honked the horn twice, let the guard in the duty room move the barrier at the door, raised the bar at the door, and then drove the car in.


    When Qin LAN drove the car in, the two guards at the door saw that the car was dragging fresh vegetables. Their eyes brightened a lot and they couldn''t help swallowing.


    After the disaster, although there was no shortage of materials in the police station, we didn''t see any fresh green vegetables for nearly two months.


    Although the greenhouse in the underground air raid shelter can produce fresh mushrooms, to tell you the truth, it''s really good to use mushrooms to fill the stomach and provide nutrition. It''s also delicious to use them to cook soup or roast them. But after eating mushrooms for two months in a row, everyone would like to have some fresh green vegetables.


    This kind of time can eat a fresh green vegetables, which afraid of raw chewing, will also make people feel delicious.


    However, the guard thought that he might just think about it. After all, it''s just a few hundred jin of vegetables. Even if it''s used to make soup, it''s not enough for the people living in the city police station to make soup one by one.


    After all, there are thousands of policemen and their families living in the underground air raid shelter of the city police station. Although the total number is not as many as the three shelters in the city, each shelter has 50000 or 60000 people, there are still more than 20000 people.


    Hundreds of Jin of vegetables, more than 20000 people, really can only one person a mouthful of soup, taste the taste.


    In fact, it''s impossible for one person to share these hundreds of Jin vegetables, because these vegetables are exchanged by the special police force. Of course, these vegetables are also materials under the name of the special police force, and it''s impossible to take them to all people.


    So when Qin LAN drove the car to the garage, before the car stopped, several SWAT team members waiting here directly climbed on the car and carried down the box with vegetables like a snatch, it was no surprise.


    but Lan Qin jumped down from the car and watched several officers seem to grab the same movement. Or did they make complaints about them? Haven''t you eaten fresh vegetables in two months? There will be every month in the future. Don''t be like robbing! "


    "Don''t say that, Qin LAN. We''re not afraid that other people will see us. Do we want to share it?" A policeman who is carrying the box says to Qin LAN, but the action of carrying the box is not slow at all.


    Hearing him say so, Qin LAN is not easy to say anything. Although this is a little destructive to unity, it is also true.


    In addition to the Municipal Police Bureau itself, there are four branches, more than ten police stations and various branches in the city. In fact, there are quite a few departments.


    Although we are all police officers, there are still differences between departments even in normal times. It is not said that any department that has made good things to distribute benefits will benefit other departments.


    Only if there is too much for them to use up, will they share a point with the brother department that has a good relationship with them.


    In today''s Doomsday environment, all departments pay close attention to their own materials. Although the food is distributed uniformly, all departments have more or less accumulated some good things for themselves before the disaster. In addition, the materials collected and exchanged after the disaster constitute the private warehouses of all departments.


    Qin LAN and the police officers carrying vegetable boxes went down from the elevator in the garage to the underground shelter. The vegetables they were carrying naturally attracted a lot of attention.


    In the past two months, in order to save materials, rationing system has already been implemented in the shelters. Although the food allocated is enough, everyone will want to eat better. In fact, the private coffers of various departments play such a role.


    It''s not selfish. It''s not too much to think about yourself when you can''t hurt others.


    In this eschatological environment, if we really distribute materials according to the standards of fairness and selflessness, it will not create a perfect collective of unity, but will only make everyone work hard, and eventually lead to no food for everyone.


    The average is the biggest injustice in the world, because there are always people who do more, and there are always people who do less.


    If they get the same results, what will people who do more think and people who do less think?


    Yanguo had an average system under the collective, which was to do more and less, but it turned out that the people who made this policy underestimated the selfishness of human nature.


    Qin LAN and others through the corridor of the underground shelter, back to the area where the SWAT team is located.


    The underground shelter of the police station covers a large area, because it was built as an air raid shelter before, and then it was expanded and reinforced. The place is really not small.There are not only rooms for people to live in, but also canteens and offices, which can be used as an underground base.


    According to the original division, there are offices, residential areas, activity rooms, and even a canteen and conference room. It''s just like an independent small area, with no entrance or exit.


    This is a very common situation for these underground shelters built in the last century in our city. After all, they have been built three or four times. The earliest part of them can be traced back to more than 40 years ago. It is not surprising that they have been expanded into such relatively independent small areas.


    In that special era, the city was part of the national defense project known as the third tier. Not only a large number of national defense facilities were built, but also the 6501 project, known as the seven top secret projects, was built in the suburbs of the city.


    Although it has been abandoned for a long time, it has to be said that the fortification known as the underground Great Wall has indeed played a great role in this context. A considerable part of the people outside the city are resettled there.


    These relics from that era, the fortifications originally used to deal with the possible war of aggression, became the key and foundation for Yanguo to settle down most of its people.


    After being assigned to this area, the special police team has carried out some transformation. Instead of using the office as an office, the office has also been changed into a living room. The activity room has become the private storehouse of the special police team, and some materials, guns and ammunition have been concentrated here.

 Chapter 57

    When Qin LAN brings people back, uncle Ding has been waiting at the door of the private library.


    Seeing that Qin LAN came back with vegetables, he nodded to Qin LAN and said, "Xiao Qin, it''s hard. Is nothing wrong on the way? "


    "Thank you for your concern. There was no problem along the way. This is the 400 Jin vegetables exchanged from a Xin, 200 Jin cabbage and 200 Jin lettuce. He will give us the rest after harvest next month." Qin LAN saluted uncle Ding, and then reported the exchange to him.


    Looking at these vegetables, uncle Ding nodded with satisfaction, motioned to put them in the private library, and then said to Qin LAN, "Xiao Qin, you come with me. I have something to ask you."


    Qin LAN nodded, did not ask, just followed Uncle Ding through the corridor to the conference room.


    The conference room has now become the office of the special police force. There is a big table in the middle, on which the current map of the city is spread. The major shelters are listed, and a lot of data and patrol routes are marked on it.


    There are several huge file cabinets around, and even two weapon cabinets. One of them is open, and you can see the guns inside. Next to the gun cabinet is a huge indoor planting box, in which some green plants are growing.


    Because of his daughter''s relationship with Mo Qingyan, although uncle Ding is the captain of the SWAT team and can reasonably be divided into a room, he didn''t want it. Instead, he put up a camp bed here in the conference room and pulled up the curtain to make a small partition, which was his own private space.


    Uncle Ding took out two tea cups from one side of the cabinet, and took out a small tea can from the small space behind the curtain for a long time. After opening it, he twisted a few pieces of tea from inside and put them into the cup.


    Seems to think a few pieces of tea is a little too stingy, so quite distressed to twist out a few pieces of tea into one of the cups, and then covered.


    "Xiaoning, is she OK?" Like casual inquiry, uncle Ding added boiling water in the cup and pushed the cup with more tea leaves to Qin LAN.


    "Ding Ning is very good. There is no shortage of materials for Qing Yan. The situation here is better than ours. Ding Ning is still in a mood for the captain. You ask her to magnify the fake." Taking the cup and looking at the few dozen pieces of tea in the cup, Qin LAN reports his daughter''s situation to Uncle Ding.


    Hear Qin LAN say Ding Ning situation is OK, uncle Ding this just grew a breath, but the face still maintain a serious expression.


    "Xiao Qin, what do you think of Xiao Chen?" Uncle Ding changed the topic and talked about the transaction with Chen Xin: "it''s really a worthwhile business to trade materials for vegetables from him, but is he reliable?"


    It seems that he is afraid that Qin LAN doesn''t understand what he means, and he adds: "I mean, can his vegetable output be guaranteed? If there are only a few hundred jin of vegetables a month, and the supply can not be guaranteed, then the matter is not so... "


    "On this point, I think ah Xin''s vegetable production can be guaranteed. He has a greenhouse for planting, and now he plans to expand it for hydroponic cultivation, so the yield should be improved." Qin LAN told the truth, neither because of his past relationship with Chen Xin to say a good word for him, but also did not deliberately hide anything: "this transaction I think can be done, but ah Xin''s vegetable output is stable, on the contrary, we have no stable output to exchange."


    "It''s really a problem." Uncle Ding frowned, drank a sip of tea and thought, "does Xiao Chen smoke?"


    Cigarettes, before the disaster is a very common consumer goods, good cigarettes are not only expensive to sell, but also a very common gift in the contacts of Yanguo people.


    After the disaster, such things that are not necessary for survival can not be stored as materials. However, the special police team can still get a little from the materials allocated by the municipal government every month. Uncle Ding thinks that if Chen Xin smokes, this is a pretty good trade product.


    You know, in the black market of shelters, a pack of cigarettes can change a lot.


    However, Qin LAN shook her head and said, "ah Xin, he doesn''t smoke much. Although he drinks, he doesn''t drink much, and he can change from Qing Yan."


    Hearing Qin LAN say so, uncle Ding can''t help feeling some regret, but as a veteran smoker, he can''t help but feel a little lucky. He has smoked for decades, but if he quits all of a sudden, it will be very uncomfortable.


    "Xiao Qin, what do you think we should do to maintain this deal with Xiao Chen? Now, as you know, Xiao Qin, if you can produce hundreds of Jin more vegetables every month, it will be very helpful for the special police force. " Uncle Ding asks Qin LAN for her opinions.


    But Uncle Ding doesn''t pay attention to it. Although the food in the shelter can be guaranteed, there is still a shortage of everything. There are hundreds of kilograms of vegetables every month. Whether you eat them or exchange them for other materials, it can greatly improve the living conditions of the special police force.


    Qin LAN couldn''t think of any good idea for a moment, but after thinking about it, she said, "maybe we can exchange our daily necessities with him? He''s just a person. It''s not convenient for him to get toothbrush, toothpaste, towel and soap. We can consider exchanging these living materials. "Hearing what Qin Lan said, uncle Ding nodded in agreement, but he didn''t make a final decision. He just said to Qin LAN, "I know about this matter. Xiao Qin, please go ahead. I''ll discuss it with the political commissar later."


    Qin LAN didn''t say much, just left the meeting room with a salute.


    Qin LAN, who left the conference room, went to her residence and planned to have a good rest. Today, she was a little tired after a busy day.


    "Sister Qin!" Just as Qin Lan was walking to her house, a little girl who looked only four or five years old suddenly appeared and said hello to her happily.


    "Huihui! What are you doing here? Where''s your mother? " Qin LAN looked at the little girl with some surprise, squatted down and said this to the little girl.


    This is a little girl named Huihui who lives next door to Qin LAN. Her father is also a member of the special police team, and her mother is a civilian of other departments of the Municipal Bureau. When they allocated accommodation, their family lived with Huihui''s father to the special police team.


    However, Huihui''s father is not in the shelter of the police station now, but is stationed in the shelter of the pedestrian street as a necessary deterrent to maintain the order in the shelter there.


    "Mom went to work. I was feeding the bread bug." Huihui with a little proud expression, said to Qin LAN with pride.


    Huihui said that the bread worm is a kind of insect that is distributed to each family in the shelter. It is a kind of insect with high protein, and it is easy to raise. It can be raised in a dry cage with a little food residue. Even a child of Huihui''s age can complete this kind of work.


    Just so small children need to do these things, or let Qin LAN can''t help but feel a burst of heartache.

 Chapter 58

    Among the materials Chen Xin exchanged from Uncle Ding through Mo Qingyan, in addition to the materials used to upgrade the greenhouse, there are also materials used to upgrade the weapon cabinet.


    Chen Xin, who has spent all of his survival on upgrading the greenhouse, has to wait for the new survival to arrive before he can upgrade the weapon cabinet.


    "Simple iron weapon cabinet"


    "upgrade scheme 1: upgrade cabinet material, enhance cabinet volume, add weapon maintenance and transformation function, existing weapon technology level + 1, upgrade survival 500"


    "upgrade scheme 2: upgrade cabinet material, enhance cabinet volume, add gun manufacturing module, obtain gun manufacturing drawing + 1, upgrade survival 450" ¡±


    "do you provide steel, file, claw hammer, vise, hand drill and other materials for upgrading?"


    "Scheme 1 materials have been provided, the survival points required for upgrading are reduced by 90%, and the survival points required are 50 points"


    "scheme 2 materials have been provided, the survival points required for upgrading are reduced by 90%, and the survival points required are 35 points"


    "scheme 1 and scheme 2 upgrade materials are met at the same time, the survival points required for upgrading are reduced by 25 points, and the survival points required are 60 points. Do you want to upgrade?"


    After upgrading the planting greenhouse, Chen Xin has gained 13 survival points every day, so after saving for a week, he can upgrade the weapon cabinet.


    Naturally, Chen Xin chose to upgrade directly.


    The upgraded Guanghua flashed by again. The weapon cabinet, which was originally just a green tin cabinet, became a bigger and stronger dark green cabinet after Guanghua disappeared. At the same time, there was a workbench with tools beside it. There was a weapon rack on the workbench, but now it was empty.


    Chen Xin can''t wait to open the weapon cabinet. The weapons originally placed in the cabinet have changed qualitatively at this time. It''s obvious that the "existing weapons technology level + 1" in the upgrade plan has already taken effect on these weapons.


    The change of the two daggers is not obvious. Chen Xin doesn''t pay attention to them. The first thing he takes out of the weapon cabinet is the American hunting bow that Mo Qingyan gave him before.


    The American hunting bow is considered to be a bow type originated from the Indians. The most important feature of the bow type is that it has an arrow platform. It usually has two bow types: straight bow and reverse bow. Chen Xin''s one-piece reverse bow, which was originally made of pure wood, was also a gift from Mo Qingyan when he joined Mo Qingyan''s outdoor shop.


    But now the wooden bow has changed a lot. Instead of the original wood, the bow body has become black carbon fiber. The handle has also become metal and engineering plastic. There is also a laser sight and ruler on the original platform.


    Only the bow type of this bow is still the previous reverse bow, and it has not become a composite bow with higher technology level.


    Although he preferred the handle of the original wooden bow, Chen Xin still tried to pull the bow string and wanted to try the handle and strength of the bow.


    With this pull, Chen Xin found that when he opened the bow, it was much easier than before, but when he let go, the sound of the bow string rebounding was still loud.


    Although no test has been done, Chen Xin can be sure that the tension of the bow has not decreased. On the contrary, it seems to have been improved.


    Chen Xin didn''t understand the principle, but he thought it had something to do with the material and structure of the bow arm.


    After putting the bow back in the weapon cabinet, Chen Xin checked his own quiver. However, it seems that this one is not included in the category of weapons, so it has not been upgraded.


    However, the arrows in the quiver have changed from Chen Xin''s glass fiber arrows to carbon fiber ones. Even the arrows have been upgraded, from a conical blunt head to a triangular pointed head. You can feel the edge of the arrow when you reach out.


    Chen Xin can''t help touching his nose. This thing has become a little dangerous.


    However, the original technology level of arrow is not high. Even if it is upgraded, there is no high-tech explosion arrow or other more dangerous things, which makes Chen Xin feel some regret.


    Perhaps in the original world, these are all controlled dangerous weapons, but in the doomsday world, everyone hopes that the more powerful the weapons used to ensure their own safety, the better.


    Besides the bow, the samurai sword in Chen Xin''s weapon cabinet also changed a lot.


    Originally, the wood handle wrapped with cloth became the material of engineering plastics. The handle with anti-skid texture is very comfortable to hold. The sheath upgraded from wood to metal is also a matte and frosted surface. When the color becomes black, there is almost no reflection.


    "Not bad!" Although there is no knife drawn, just the feeling of holding and the weight of the scabbard in the hand give people the feeling that it is a good knife.


    Chen Xin doesn''t know much about bows. Playing with bows and arrows is just a matter of being pulled to her club by Mo Qingyan to shoot a few arrows occasionally. But he is an obsessive fan of knives.


    This samurai sword was originally a real ancient craft which he bought from Yingzhou in the name of handicraft through many relationships.


    In order to buy this knife back, when he entered the state of Yan from Yingzhou at that time, he chose not to cut the blade. After Chen Xin received the knife smoothly, he asked professionals to cut the blade a little bit.The so-called "Bei Qian Dao" refers to the "Bei Qian Dao" of the five major Dao systems in Yingzhou, of which Chang Chuan is a branch.


    Among the five major sword systems in Yingzhou, Beiqian sword belongs to the best one in quality and quantity. The branch of Beiqian long boat has a long history, and there have been many famous swords in the history, such as Sasaki Kojiro''s Beiqian long boat Changguang and Yingzhou Warring States period''s famous sword Beiqian long boat cum Guang.


    Although this Dao is not so famous for novice Chen, it is also a good one.


    The scabbard and handle can only be regarded as external decoration. They can be replaced at any time. It''s the blade itself that really decides whether a knife is good or bad.


    After taking a deep breath, Chen Xin directly pulled out the love Dao named Sakura cut by himself, and wanted to see what changes have taken place after upgrading this beloved Dao.


    With Chen Xin''s action, a dark blade, like ink, slid out of the scabbard, and there was no reflection like the scabbard.


    This makes Chen Xin a little surprised. It''s the first time for him to see this kind of completely non reflective blade. Even this kind of pure black blade in the game is rare.


    Chen Xin carefully observed the blade and gently touched it with his fingers. He clearly felt the sharpness of the blade, as if it had been ground very carefully.


    But even so, the blade is still pitch black, as if the material itself is pitch black.


    What''s strange is that the blade doesn''t feel as matte and frosted as a scabbard, but as smooth as a mirror, which surprised Chen Xin.

 Chapter 59

    Lay the blade flat and hold the blade close to tan with only one finger. He wanted to feel the center of gravity of the blade.


    Feeling that the blade was balanced, Chen Xin released his hand holding the handle. Under the action of gravity, the blade stood up on Chen Xin''s fingers with the back of the blade.


    This is a characteristic of samurai sword. If it is well cast, when the finger is placed at the center of gravity of the blade, the blade will stand up by itself with the back of the blade under the action of gravity, and can be held by one finger.


    Seeing that the black knife was firmly standing on his finger, Chen Xin showed a satisfied smile at the corner of his mouth, hooked his finger, rotated the blade and grasped the handle.


    Holding the knife lightly, Chen Xin could not even feel the weight of the blade, as if he was holding only a feather.


    But in addition to its lightness, the knife does not give the holder a feeling of lightness. When wielding the knife, he can still feel the process of power transferring from the handle to the tip.


    Chen Xin is very satisfied with the change of his love for Dao, especially when he makes a chopping action with the Dao and the blade doesn''t make any sound.


    "It''s a good knife, but it''s not concealed by a gun." Although Chen Xin couldn''t put down his love for the new sword, he still put it back in the weapon cabinet after a bit of rubbing and playing.


    His purpose of upgrading the weapon cabinet is not to upgrade these weapons, but to obtain the capability of gun manufacturing.


    He pulled back his chair and sat down in front of the extra workbench next to the weapon cabinet. Chen Xin simply checked the tools on the table. Some of them he knew, but some he had never seen.


    After picking up a few tools at random and putting them back in their original places, Chen Xin found the drawings of the guns obtained after upgrading the weapon cabinet from the drawer of the workbench.


    "Drawing of 7.62mm double trigger semi-automatic pistol"


    "required parts: barrel, sleeve, re-entry spring, trigger, hammer, safety device, gun handle, cartridge clip"


    "parts can be processed by tool table or parts can be completed by survival"


    on the drawing is a pistol with familiar shape, some of which are similar to M1911, but there are some differences.


    However, Chen Xin is not a pistol enthusiast, and he doesn''t have a deep research on it. What he cares about is how to make a gun, not what kind of pistol it is.


    Through reading the drawings and consulting the instructions provided by the system, Chen Xin finally knows how to use the tool table in front of him to make a pistol.


    First of all, Chen Xin must have raw materials. If there are no or unqualified raw materials, he can spend the survival to supplement or improve the quality.


    Secondly, according to the size of the drawing, the tools on the tool table are complete, which can fully meet the needs of processing parts.


    It''s just that it''s a bit of a test of Chen Xin''s craft. If the machining accuracy is not enough, obviously there is something wrong with the pistol.


    Of course, it can also cost survival to make unqualified parts qualified.


    If you really want to save time, you can also directly spend the survival to make parts, but if you do, it will be a little more expensive than your own processing.


    As for the assembly of parts, it can''t be replaced by survival. The system only provides 3D dynamic assembly diagram, and Chen Xin needs to do the assembly himself.


    Knowing this, Chen Xin immediately wanted to make a pistol.


    In terms of raw materials, Chen Xin only needs to spend 2 survival points to improve the quality of steel because there is still steel left in the previous exchange.


    As for self processing, Chen Xin hesitated for a moment and gave up the idea. Instead, he chose to spend another 3 points to survive and let the system help complete the processing.


    Looking at the neatly placed parts on the workbench, Chen Xin restrained his excitement and called out the assembly diagram provided by the system. After carefully looking at it twice, he confirmed that he had clearly remembered the steps, and then he started the assembly.


    Carefully assembling each part according to the system''s instructions, Chen Xin''s action is quite slow. Compared with those people on TV who can quickly assemble guns blindfolded, Chen Xin is obviously a layman.


    But even so, he still stumbling to assemble the gun.


    After inserting the cartridge clip, Chen Xin pulls the sleeve and holds the pistol, which he has assembled by himself. Chen Xin makes a handsome aiming posture.


    "Bang!" With a bit naive mouth simulation gunshot, Chen Xin this will be the pistol back to the workbench.


    Gun is a familiar and strange thing to Chen Xin.


    Which boy didn''t play with a gun when he was a child? Even though they''re not real guns.


    Strange to say, thanks to the total ban on guns policy of the people''s Republic of China, it is very rare for ordinary people to see guns in their lives, not to mention touching them.


    Of course, even if Chen Xin has never seen a gun, he knows that the gun he assembled is useless except to scare people.


    Because it also lacks an important component, that is, bullets.The power of a gun depends largely on the bullet rather than the gun itself.


    The gun itself is just a platform for firing. Although it has a certain impact on the power of bullets, the advantages and disadvantages of the gun itself are more to affect the shooting accuracy than the power.


    In fact, most shooting games subconsciously ignore this point, leading many people to think that as long as the gun has bullets, it can kill enough. The better the gun, the more powerful it is. But in fact, it is not the case.


    Chen Xin''s pistol uses 7.62mm caliber bullets, and the clip can hold 12 bullets.


    This is an international model of bullets. Many countries in the world are using this caliber of bullets, not only for pistols, but also for machine guns.


    Of course, pistol bullets and machine gun bullets are still different in length. In general, the length of pistol bullets is 17mm, that is to say, the standard specification of 7.62mm pistol bullets should be 7.62 ¡Á 17mm.


    Since the worktable has the function of making firearms, bullets, as an important part of firearms, naturally will not be less.


    It''s just that Chen Xin, who doesn''t have gunpowder, still needs to spend 1 Survival point to supplement materials if he wants to make bullets.


    Fortunately, it''s easier to make bullets than to make gun parts, especially when there are machines. It took Chen Xin only some time to make a box of bullets.


    The bullets were filled into the magazine one by one, and then inserted into the handle of the gun. Chen Xin pulled the sleeve again, but this time one bullet had been pushed into the gun.


    Chen Xin, who is afraid of fire, turns off the trigger''s safety, pulls out the cartridge clip again and presses a bullet in. Then he inserts the cartridge clip back and touches the pistol, feeling a great sense of security.

 Chapter 60

    With the gun, Chen Xin felt that his safety had been greatly guaranteed and improved, so he had the idea of going outside.


    Although there''s nothing to look at outside now, it''s a part of doomsday survival to pick up rubbish. We have to experience it, and we can also understand the external environment.


    However, even with a gun in hand, Chen Xin feels that he should be well prepared to go out.


    At the very least, a protective suit that can completely wrap itself up, a gas mask that can be used for a long time in the external environment, and a strong flashlight that can provide good lighting must be prepared.


    In addition to these, water bottles, medical bags, and even carry on food, all need to be prepared.


    Chen Xin, of course, has already made preparations for the gas mask. Medical bags, water bottles and flashlights are all ready-made. There is no problem in going out to explore.


    The only thing that worries Chen Xin is protective clothing.


    At this time, Chen Xin has learned something about the external environment through the previous two exchanges of materials. Two months after the meteorite fell, the external temperature has begun to drop. At present, although it has not dropped below zero, it is relatively cold.


    If it was before the disaster, Chen Xin would have moved out the oven to burn at this temperature.


    So if you want to go out, warm clothes are necessary.


    It''s easy to say. After all, it''s silly to know that the temperature will drop to dozens of degrees below zero in the future and not prepare warm clothes.


    Chen Xin''s wardrobe does not say, down jacket, winter jacket these are two.


    Just considering the external environment, Chen Xin doesn''t basically stay in the car as before, but needs to be exposed to the external environment for a long time. Therefore, in addition to keeping warm, his clothes should also have certain protective ability.


    The protective ability here is not radiation protection, but skin contact with toxic and harmful ingredients in the air.


    In fact, the harm of toxic and harmful components in the air is more serious than radiation. Once some gases enter the human body through breathing, it will cause dizziness, dyspnea, shock and other symptoms, and even cause death in a short time.


    And some gases are more serious, even if only through skin contact, it may cause redness, ulceration, peeling, chapping and other injuries. Contact with eyes or mucous membrane will produce strong irritation, cause redness and swelling and many other reactions, and even lead to blindness.


    Originally, if it was just a big fire, there would be more toxic and harmful gases such as sulfide and carbon monoxide in the air, but there are many large chemical plants around the city.


    As a matter of fact, Chen Xin grew up in a chemical plant. At the beginning, his family lived in the family area of the plant, because all the people around him worked in the chemical industry. Under his influence, Chen Xin knew the dangers of toxic and harmful gases very well.


    Especially when he was a child, Chen Xin once saw an accident on his way home from school.


    At that time, at a maintenance site, a migrant worker who was working on the site fell into a spherical tank used to store chemical gas.


    When he was rescued, his skin was dry and cracked, as if he had been dehydrated by exposure to the sun, and there were layers of dandruff on the surface of his skin, even his eyes turned gray, and his hair was like dry straw.


    Chen Xin, who was less than 10 years old at that time, was shocked by the tragedy of the migrant worker, leaving him with a deep psychological shadow.


    So for toxic and harmful gases, Chen Xin has been afraid since he was a child. If he does not have enough protection, he will not take risks.


    What''s more, although chemical plants are very important for post disaster reconstruction, the municipal government should repair these chemical plants as soon as possible. Unfortunately, most of these chemical plants are special grade fire prevention units. Once a fire breaks out, it will cause an explosion


    Chen Xin also doesn''t know how damaged these chemical plants are, but it is certain that the air quality in this city must be very poor.


    Two times before I went out, one was driving, and the other was just staying at the gate of the shelter for a while. Both times I was not exposed to the external environment for a long time, so it was not a big problem.


    However, since the decision is to go to the waste soil to pick up garbage this time, it is obviously impossible to stay in the car all the time. It is necessary to stay in the potentially dangerous environment for a long time.


    In fact, for the survivors in the doomsday environment, unless they have to obtain resources, it is the most wrong way to leave the safe environment of the refuge.


    Because in the last days, no one knows what kind of crisis lurks in the once safe environment. It may be a potential zombie in a rotten zombie film, or it may be a gangster of wasteland, or it may be an invisible and fatal threat


    So when you can be self-sufficient, the safest thing is to stay in the shelter and not go anywhere.


    But Chen Xin still decided to go out once. The reason is not to experience the life of picking up garbage, but to go out for a walk, to have an overall understanding of the current environment, and to search for materials that may exist.Although the previous fire caused by meteorite fall burned almost everything, it does not mean that nothing can escape this disaster.


    For example, in some places such as supermarkets or grocery stores, although the storefront on the street will be burned out of shape, the warehouse in the store may not be able to survive.


    If Chen Xin can find such a warehouse that has not been burned down by the fire, even if he just finds a few bottles of feizhai happy water, it will be worth the ticket price.


    If you want to go out, protective clothing becomes the top priority.


    A set of qualified protective clothing should not only be able to wrap the body and avoid skin exposure as much as possible, but also need acid-base resistance and corrosion resistance. If it is used in a chemical plant, it even needs antistatic.


    For example, in death stranded, the protagonist is dressed as a courier, or a Rhode Island officer uniform.


    Both of them are often active in dangerous environment, and their clothes are protective clothing with certain protective function.


    In today''s external environment, it''s very normal to have acid rain. If you can''t have good protection performance and get drenched in acid rain, it''s not a pleasant experience. You may even have to literally peel off your skin.


    If there is no system, Chen Xin may restrain his mood and find Qin LAN to get a protective suit when he exchanges materials next month.


    The special police team is responsible for maintaining the security of the major shelters. If they need to go out of the field, a set of safe and reliable protective clothing will still appear in their equipment.


    However, since there is a system, Chen Xin has another choice.

 Chapter 61

    Open the wardrobe, Chen Xin plans to find a coat to upgrade, through the system to create a protective clothing.


    All of Chen Xin''s clothes are hanging in the wardrobe, including ordinary coats, down jackets necessary for winter, and the cold proof clothes and outdoor equipment he used to use when he and Mo Qingyan lived together in the wild.


    Chen Xin thought about it. Instead of taking an ordinary coat or down jacket, he took out a red winter coat and a dark brown tactical poncho.


    "Outdoor cold proof clothing"


    "upgrade scheme 1: upgrade the long velvet cold proof liner, add the cold proof mask, improve the thermal insulation effect, improve the outer waterproof effect, upgrade the required survival point 20"


    "upgrade scheme 2: upgrade the acid-base resistant outer fabric, add the digital camouflage coating, add the protective breathing mask, improve the protective effect of dangerous environment, upgrade the required survival point 35" ¡±


    "do you provide long staple cotton, waterproof cloth, gas mask, digital camouflage paint as materials for upgrading?"


    "Scheme 2 material has provided tactical poncho, the survival required for upgrading is reduced by 15, and the survival required for upgrading is 20, so whether to choose upgrading or not"


    this is the first time Chen Xin has chosen upgrading items. Although the upgrading method seems to be similar to the previous upgrading of other things, it is obvious that upgrading items is not so much upgrading as props synthesis.


    The tactical poncho is used as the upgrading material of the cold suit, but the upgraded cold suit obviously has the function of the tactical poncho.


    After some consideration, Chen Xin chose to upgrade, and also added an old down vest, which further reduced the survival of the upgrade, and improved the ability of cold protection and warmth for the upgraded cold proof clothing.


    After the upgrade, the cold proof clothing has become a long windbreaker with gray black color on the surface. The surface feels as smooth as the tactical poncho, but it feels much thicker. At the same time, there are many more velcros and tactical storage bags on the surface, which can facilitate Chen Xin to carry all kinds of things.


    Inside the clothes, there is a thick detachable down lining, which makes you feel warm.


    What makes Chen Xin feel most satisfied is that although the lining extends to the hem, it is not simply fixed on the hem. Instead, it is also wrapped with a layer of waterproof cloth, which can effectively prevent the mud splashed on the ground from polluting the inside of the hem.


    In addition, along with the protective clothing, there is a pair of pants of the same material.


    The hat originally contained in the collar has been enlarged a lot, and a waterproof edge has been added.


    It can not only ensure the head is wrapped, but also prevent the rain from floating to the face without affecting the sight.


    In particular, a detachable respirator is attached to the hat, which can wrap the whole face without additional gas masks.


    Chen Xin picked up the whole dress, put it on his body and tried it. Then he hopped twice and moved his hands and feet. He found that after wearing this dress, he could obviously feel its warm effect, and it was thick but not heavy.


    Moreover, the fit design of the arm does not affect the activity at all, which is enough for the flexibility of the body in outdoor activities.


    This makes Chen Xin feel very satisfied. Such a dress is very helpful for the external activities in the current environment.


    With protective clothing, Chen Xin finally feels that he can go out safely and boldly.


    Chen Xin also made two clips and a box of bullets from the last five survival points, and loaded the clips and 50 bullets into the ammunition bags attached to the protective clothing in case of emergency.


    This time out, Chen Xin did not drive.


    Although it would be more convenient to drive if he had to carry materials, this time he mainly explored the external environment and searched for possible materials. Walking was more hidden and flexible, and he could go deep into places where vehicles were not convenient to enter.


    As for the matter of transporting materials, Chen Xin thinks that he can move the materials after finding the place.


    After all, driving out consumes gasoline. A trip out of the car may run out of more than ten liters of fuel. Chen Xin must consider the consumption.


    Although there is no sign that all kinds of materials will be cut off at present, and there is still a way to get gasoline, in the end, any material is precious, and we must consider the economical use.


    After all the things that should be prepared were put into the backpack, the pistol was closed, the insurance was put into the tactical bag of the protective clothing, and the upgraded samurai sword was also fixed on the protective clothing with a Velcro. Chen Xin then put the breathing mask on his face, put on his hat, and walked out of the shelter.


    Although he was wearing thick and warm protective clothing and wearing a breathing mask on his face, Chen Xin still felt a little cold, and the breathing mask soon became a layer of water mist because of his breathing.


    He looked up and saw that the sky was as gloomy as before, and even darker today, almost the same as night, because it was raining.


    Although the rain is not big, or even just drizzle, with rainproof protective clothing, Chen Xin does not care about this degree of light rain, but it is not a good thing after all.Because in addition to the possible acid rain brought by the rain, the more important thing is to cool down, which is why Chen Xin still feels cold in his thick protective clothing.


    Maybe most people have experienced this experience. From September to October every year, if it doesn''t rain all the time, the weather will be very hot, as if the summer is not over.


    But once there is a rain, the temperature will drop immediately, as if autumn is coming in an instant.


    The South may be better, but in the north, after autumn, it''s really a layer of autumn rain and a layer of cool, often a rain, the temperature can drop precipically, maybe there was 30 degrees yesterday, today is only 20 degrees.


    And autumn seems to pass directly in these short rains, followed by the cold winter.


    According to the original time, it should be the end of May and the beginning of June. It''s time for the weather to gradually get hot. But now with the continuous drizzle, Chen Xin doesn''t have a thermometer on hand, but he just looks at the layer of water mist on his breathing mask. He thinks that the ambient temperature may not even be 10 degrees.


    This makes Chen Xin feel worried and worried. The temperature has dropped much faster than he expected. This is not a thing that can make people feel at ease.


    Even if he stayed in the shelter, with the ground as the insulation layer, the container house in the shelter was also insulated, but if the temperature continues to drop, I''m afraid that the consideration of heating must be put on the agenda.

 Chapter 62

    Because it''s walking, Chen Xin''s speed is not fast.


    He has a climbing stick in his hand, which can help him clear the obstacles at the same time.


    Although he was walking along the road, the roadside was not as clean and smooth as before.


    Because of the rain, the charred trees on the hillsides on both sides of the road are washed down by the rain and piled up on the roadside, with mud, stones and other things mixed in. If you walk on the road carelessly, you will easily step on or kick, or even trip.


    Chen Xin did not light up his flashlight, in addition to saving use, but also to avoid being found lighting.


    Although most of the survivors are now in the shelter, there should be few people outside, but there is no guarantee that someone is not in the shelter.


    He just came out to understand the current situation and collect some resources. The pistol is just for self-defense, and he doesn''t want to cause any trouble.


    Chen Xin continued to walk along the road. Although it was dark, he could not really say that he could not see at all, and he could not deviate from the direction when he walked along the road.


    "I don''t know if the supermarket has been emptied?" Chen Xin looked up at the front, hoping that the supermarket he wanted to go to had not been empty, and there were still materials left behind.


    Although Chen Xin also knows that this is unlikely, he still has some expectations in his heart.


    The doomsday natural disaster of meteorite impact is not like the disaster of biochemical crisis, which breaks out almost in an instant and destroys the government agencies of most countries. In fact, it is very difficult to happen in reality, because all countries have corresponding emergency plans for such emergencies.


    Knowing that a meteorite is about to hit the earth three months in advance, in addition to the series of measures taken before the meteorite falls, governments have not ignored how to resist the disaster caused by the meteorite after it really falls.


    Yanguo is the best country to deal with the meteorite disaster, whether it is the construction of shelters or the collection and storage of materials.


    For three months, most of the materials on the market have been collected by the government or the public.


    However, this kind of thing is not absolute. Although three months is enough to collect most of the materials in the world, there will still be some materials left behind.


    It''s hard to say what can be found, but if you are willing to search carefully, you can still find a lot of things.


    What Chen Xin wants to go to now is a fairly large supermarket near his home, where Chen Xin used to drive to buy vegetables and other living materials. Chen Xin wants to go there just to see if he can find some living materials.


    Although we don''t have to worry about food and drink now, although we are not unprepared for things like toothbrush, toothpaste, towel and underwear, it is good to collect more, because no one knows how long the end of the world will last and what the material supply will be like.


    Moreover, Chen Xin did not place all his hopes on that supermarket. On the way to the supermarket, there are about four or five small supermarkets and some shops, which are the main places Chen Xin wants to search.


    After all, compared with big supermarkets, these smaller stores are more likely to have materials left.


    Because the distance is not very far, Chen Xin soon came to his first destination, a convenience store in front of the residential area.


    Although Chen Xin''s home is located in the suburbs, the development of Yanguo''s cities, especially the real estate, has been very hot these years. Even in the suburbs, residential areas are gradually being built, which greatly improves the possibility that Chen Xin can search for materials.


    In fact, if he is willing to go door-to-door to collect, how can a residential area also collect a lot of useful materials.


    But for Chen Xin, he can exchange materials through the channels of the special police team, and he has a big killer system. In fact, he doesn''t need to search for materials like this.


    So Chen Xin''s goal is just to find the store at the gate of the community and see if he can find something left behind.


    Of course, Chen Xin didn''t have great expectations about whether he could find materials. Not to mention the raids before the disaster, the fire after the disaster also burned everything out of shape. How many things can survive is entirely a matter of luck.


    At the gate of the community, Chen Xin sighed.


    It''s not that he hasn''t been to the neighborhood in front of him before. Because it''s not far from his home, Chen Xin used to come back here occasionally to buy things.


    He had the impression that many trees were planted in the community, and the greening was very good. Even if he just stood at the gate of the community, he could see the lush trees in the community.


    There is also a bronze statue at the gate of the community. Although it looks like a wall street bull, as a decoration, the omen and moral are good.


    But now all the trees have been burned into a pile of coke, the whole community can no longer see any green, and the copper ox at the door is burned, revealing the fact that it is actually hollow inside.As for the row of shops at the gate of the community did not escape from the same fate as those in the city, which were charred. Everywhere there was a mess after the fire.


    Especially at this time, the sky is still under light rain, rain washed, black sewage flow everywhere.


    Even if it''s dark and you can''t see anything clearly, you can still feel an unspeakable desolation under the drizzle.


    "Human beings It''s really fragile. " Chen Xin stands at the gate of the residential area, looking at the deformation of the original copper bull burning on the location, can not recognize the original "copper bull", can not help but spit out such a feeling.


    Although human civilization seems to be powerful and prosperous, how much difference can human civilization make from this burnt copper ox in the face of this doomsday natural disaster?


    It''s just that human civilization can survive now, and this copper ox has turned into a beach that can''t see its original appearance.


    However, the vitality of human beings is very tenacious. Although human civilization has almost collapsed overnight, as long as we are not extinct, we will be able to rebuild all this one day.


    In the era of the lowest ebb, the population was once only a few thousand, but still survived the disaster and established a prosperous human civilization. Therefore, Chen Xin is not worried about the problem of human extinction.


    Even if modern humans are no longer the ancestors with strong survival ability in ancient times, and their bodies become weak and unable to adapt to the wild environment, the erectus ape with the most intelligent brain of Bluestar has never become the top of the food chain by strength.

 Chapter 63

    Chen Xin bypasses the gate of the community and comes to the place where it used to be a convenience store. He looks up at the place where it used to be a signboard light box. There''s nothing left there, even the iron shelves don''t exist.


    The owner of the convenience store remembers to close the door well before he leaves. He hopes that the country can prevent the disaster before the disaster.


    However, whether the country or the world is concerned, human beings have not stopped this disaster after all. The disaster caused by the meteorite fall still destroyed everything that had been.


    Chen Xin knocked on the closed door of the convenience store with his climbing stick. The turnstile was still strong. Although it was not burnt, it still kept its original appearance.


    Chen Xin banged up with his climbing stick, still locked as before, blocking everything outside.


    This makes Chen Xin look forward to it. If the turnstile is intact, it undoubtedly means that the store should not be damaged or ransacked, and the probability of finding materials is also greatly increased.


    Although he didn''t know what he might find, Chen Xin was obviously excited and looking forward to it.


    Just want to go in, or to open this is still in the dedicated turn gate.


    Try to mention it, Chen Xin did not mention it, obviously the boss had locked the door before he left.


    However, it''s not difficult for Chen Xin. The structure of this kind of revolving gate is not complicated. Besides using the key, it''s no trouble to open the door violently.


    After pulling out the upgraded Sakura cut, Chen Xin didn''t put out any sword structures or moves. He just stabbed the bottom of the rotary gate into the place where it was connected with the door frame, and then cut off the locking mechanism inside.


    After upgrading, the cherry cutting blade has become very sharp, and the turnstile has been burned again. Chen Xin just used some strength to destroy the locking mechanism of the turnstile.


    After the turnstile was destroyed, although the convenience store still had a glass door, it couldn''t stop Chen Xin.


    Walking into the convenience store, Chen Xin looked around. Although the store was not eroded by the fire, there were still traces of being roasted and burned, but it was not serious.


    But even so, the shelves are still empty, and there are not many things left.


    Chen Xin takes out a flashlight from his pocket, turns it on and lights up the shelf, trying to find out if there is anything left. After all, although the shelf is empty, it doesn''t mean that there is nothing left.


    Food and water must have been emptied, but Chen Xin found something left on the shelf near the convenience store.


    Two slightly burnt wooden handle cloth mops, three kitchen knives and four or five spoons, as well as two pieces of burnt soap wrapped in wrapping paper.


    There was a bottle of shampoo, but unfortunately, the plastic shell was baked and melted, and the liquid in it flowed all over the floor. It looked very bad.


    Although mops are not very useful, they may still be used for sanitation in shelters. As for kitchen knives, spoons and soap, these are the immediate gains.


    Taking a plastic bag out of his backpack, Chen Xin, with some excitement of picking up the garbage, put the things in the plastic bag before putting them into his backpack.


    The excitement of finding these materials makes Chen Xin want to find more things. He takes a flashlight, carries his backpack again, and walks to a small room in the convenience store, which is a small warehouse for storing some goods and collecting express.


    The small warehouse gave Chen Xin a surprise. Although most of the goods had already been emptied and most of the remaining things were damaged by the fire, Chen Xin was lucky to find a box of happy water in feizhai which was not burned down.


    This box of happy water is all pop-up cans. Obviously, the metal cans are more resistant to fire than the plastic bottles on the side, so that they can survive the fire.


    After a careful inspection of these happy water tanks, although a few of them may have been roasted in the previous fire, and they are still a little swollen, most of them have not changed.


    It''s a real surprise!


    Chen Xin hasn''t drunk happy water for a long time. When he was storing supplies before the disaster, he only wanted to collect survival supplies. These things that were easy to buy immediately became scarce after the disaster. It was a luxury to drink happy water again.


    To find this box of happy water is really heaven''s blessing for Chen Xin.


    In addition to this well preserved box of happy water, there are also half a box of canned beer in the small warehouse, which also survived because it was a metal can, which surprised Chen Xin.


    Chen Xin just thought about it in less than a second. He put down his backpack, took out the kitchen knife and soap that had just been put in the backpack, and stuffed several cans of happy water into the bag. After hesitating for a moment, he put the soap in the plastic bag and put it into the side bag of the backpack.


    As for the kitchen knife found, Chen Xin kept it and prepared to take it next time.


    He took out his kettle and drank some water. After a short rest, Chen Xin continued his exploration.It seems that the convenience store ran out of luck, and other stores in the community did not bring Chen Xin any new harvest.


    Most of the stores have been moved clean, and some stores with materials are in a mess because of the previous fire. Some leftovers are mixed in the blackened ashes. It is not easy to pick out the things that can be used.


    Chen Xin did not find anything useful.


    Although he knew that if he searched the neighborhood carefully, he could still find some useful things, but he didn''t spend so much time and energy on door-to-door search.


    Because of its location, this community did not build a shelter, and Chen Xin did not spend much time here.


    After putting all the things he had found in the convenience store together, he still put them in the small warehouse and blocked the door of the warehouse with a shelf, Chen Xin pulled the shutter of the convenience store and went on.


    The sky is still under the light rain, thin raindrops hit on Chen Xin''s protective clothing, came a rustling sound.


    Rain is not clean, which is mixed with dust, even if it does not fall to the ground, it has the same color as sewage.


    Fortunately, Chen Xin''s protective clothing itself is not stained with water, and the gray and black digital camouflage is also very resistant to dirt. Although rain and mud are the same color, Chen Xin''s protective clothing is not stained, but a few black mud spots are left on his breathing mask.


    If it is in the past, walking in the drizzle of Jiangnan with an oil paper umbrella, it is undoubtedly a thing full of poetic and romantic.


    But under the dark sky of the last days, there is nothing but heaviness and suffocation.


    Chen Xin''s ears were filled with his own breathing voice. He could not see any light in front of his eyes and walked heavily.

 Chapter 64

    In the garage of the city police station, Qin LAN, together with other special police, is sorting out the equipment. Today, they have a field mission to receive a batch of equipment from the railway station.


    "Li Tou, what equipment are we going to receive today?" When Qin LAN checks the gun in his hand, the team-mates next to him ask the leader curiously: "usually receiving materials, aren''t they all from the city government? Why do we need our SWAT team to receive equipment today? "


    "You didn''t listen to team Ding''s briefing with the political commissar just now? It''s a batch of vital materials for the shelter, so this time it''s an armed escort, and we need the special police team to receive it. " The leader known as Li Tou is also a field equipment, while checking the ammunition while answering the questions of his subordinates.


    But after hearing Li Tou''s answer, Qin LAN had some questions. She asked Li Tou, "Li Tou, shouldn''t escorting and escorting be done by the armed police? How did we get the Swat on? "


    In Yan state, the armed forces controlled by the state are divided into three parts: the army, the police and the armed police.


    Among them, the army is responsible for external operations and safeguarding national territorial sovereignty, while the police is responsible for maintaining social order and cracking down on crimes at home. The armed police is between the police and the army, not belonging to the police, but is established according to the requirements and establishment of the army, mainly responsible for local security and handling emergencies.


    In terms of functions, escorting important materials should really be a matter for the armed police.


    Li Tou himself has some doubts about this problem, but now that the tasks have been assigned, it is impossible for them to say that they will carry out the task after making it clear.


    So Li Tou can only say to Qin LAN: "maybe it''s the ghost that the city government is doing. Now it''s different from before. I''m afraid some things don''t come according to the rules."


    Li Tou''s words make Qin LAN don''t know what to say. She just wants to ask why it''s not the armed police escort, but the special police. But what Li Tou said is related to the careful thinking of some people in the city government, which inevitably makes Qin LAN feel helpless.


    Although the country is still in operation and the government agencies are still in normal operation, the end is the end. Although many things look the same as before, they are actually different.


    Li Tou may also feel that what he said is not appropriate, so he patted Qin LAN on the shoulder and said to her, "don''t think so much, maybe it''s just that the armed police can''t pull out their hands? It''s not like this has never happened before. Carry out the task first, and think about it when you come back. "


    Hearing what Li Tou said, Qin Lan also pressed down the messy ideas in her mind and focused on the task.


    The disaster caused by the impact of meteorite destroyed the original human civilization. Although there are not many survivors now, they just survived.


    For these survivors, the most important thing is to survive. As for the reconstruction of human civilization, although the country is carrying out post disaster reconstruction, the progress is very slow. It is still a very long thing to really rebuild human civilization.


    The doomsday natural disaster brought darkness and cold. On the surface, everything is OK now. It seems that soon people will be able to leave the shelter and start post disaster reconstruction.


    But in fact, the real test of meteorite impact has not yet come.


    Anyone who has studied biology in junior high school knows that everything grows by the sun. Without the sun, most of life on the earth cannot survive.


    Now, the dust raised by the meteorite has covered the sky and lost the sunshine. It is not only the decrease of temperature, but also the complete end of the ecology that can be gradually restored.


    The previous global fire has burned more than 90% of the earth''s vegetation, and a lot of carbon dioxide has been emitted into the air, which has maintained the temperature drop in a short time, but without sunlight, the temperature will soon cool down.


    Many people may not have any idea about this, but just think about the four seasons on the earth. Just because the change of the direct sunlight point can make the temperature fluctuate by tens of degrees, we can understand what the loss of sunlight means to the earth.


    And there is a more critical problem, that is, without light, photosynthesis can not be carried out, without photosynthesis, carbon dioxide in the air will not be converted into oxygen.


    Oxygen is the key to life. The bigger the body, the more serious the life depends on oxygen. Only some anaerobic bacteria can survive without oxygen on earth. Other organisms, whether plants or animals, need oxygen to maintain life.


    A big fire burns not only the forest vegetation that can convert carbon dioxide into oxygen, but also consumes a considerable part of oxygen and emits a large amount of carbon dioxide.


    Although marine ecology still exists, seaweed and other marine plants can still convert some carbon dioxide, without sunlight, even seaweed can''t carry out photosynthesis, and soon the ocean will fall into the crisis of hypoxia first.


    Without oxygen, the fish in the ocean will die and the marine ecology will collapse.As for the land, the previous global fire has wiped out a large part of the land life, and burned most of the plants, and the land ecology has collapsed at that time.


    After the double collapse of marine and terrestrial ecosystems, the oxygen cycle in the atmosphere will not exist, and the oxygen content in the atmosphere will be further reduced.


    Under normal circumstances, the oxygen content in the atmosphere is 20.9%, and the oxygen content is less than 18%, the human body will begin to appear hypoxia reaction.


    It''s just like altitude sickness. At the beginning, the breathing may be slightly faster, the heart rate and blood pressure will rise, and people who are stronger may not even feel tired.


    But with the further reduction of oxygen content, it will be followed by a significant sense of fatigue, attention began to decline, thinking confusion, or even loss of consciousness, into a coma.


    If the oxygen content continues to decrease, the body will have headache, tinnitus, dizziness, nausea, vomiting and other symptoms, and even lead to death.


    Originally, there were a large number of plants on the earth for photosynthesis, and the oxygen content in the atmosphere was maintained at a relatively stable level.


    But now that the ecosystem has collapsed, it is impossible for the ecosystem to recover the oxygen content in the atmosphere by self-regulation before the sun shines on the earth again.


    Fortunately, before the disaster, mankind has three months to prepare. Although the main energy of governments during that time is on how to prevent meteorites from falling, it does not mean that countries do not have a plan to deal with the disaster.

 Chapter 65

    Perhaps many people may not have any concept of the national plan. It seems that when the country is dealing with major disasters or accidents, it doesn''t feel that there are any special measures. It seems that they are all similar measures, not like there are any plans and arrangements.


    But as a matter of fact, for most of the things that may happen, small countries may indeed have no plans, but for large countries, they have far more than one plan for disasters and accidents.


    Most of the time, what you find common is probably the preparation of the country for certain events.


    Take the familiar Federation as an example. The supreme head of state and the commander in chief of the three services are their great commanders. They not only hold the supreme power of the Federation, but also hold the most important nuclear code of the Federation.


    Therefore, in the view of many people, as long as the commander is removed, it will be enough to affect the whole Federation and make it into a leaderless situation. In other words, kidnapping the commander will make the Federation lose the ability to launch nuclear weapons.


    But in fact, according to the federal law, when the commander-in-chief is suspended or unable to perform his duties, the deputy commander will take over. The deputy commander will also be the GG and the speaker of Congress. If the speaker of Congress is on the street, there will be other senior government officials who have the right of succession.


    Even to the extreme, there is a biological and chemical crisis or a disaster of national destruction, and the whole Federation collapses. However, as long as the federal government agencies do not completely collapse, people can still be found to continue to obey the federal instructions. The most important thing is that the army obeys the orders issued by the federal government. Even if more than a dozen generals are killed, the Federation can still find them People who meet federal law take that seat, even if they choose one now.


    Only a general commander who can be replaced at any time has such a replacement mechanism. It can be imagined that for a real big country, how much preparation and plan they have for disasters and various problems.


    As one of the common problems in the underground tunnel facilities, one of the most necessary factors for human survival, the problem of oxygen has countermeasures and plans, which is a matter of course.


    "Li Tou, are these materials coming from Hubei Province?" On the platform of the railway station, a special police officer holding a gun on guard asked Li Tou.


    Because the train carrying special equipment has not come yet, although the special police are in charge of guarding, some people will feel bored and want to talk about something.


    And this task is really a bit strange. Although he doesn''t talk about it, Li Tou himself is also a little nervous.


    So when someone wanted to talk about something, Li Tou didn''t emphasize discipline as usual. Instead, he replied, "well, it should be from three towns. The municipal government didn''t say exactly what it was. It just said that it was very important materials and equipment. After we picked up the car, we had to send them to the municipal government for unified allocation."


    "What''s so important?" Another SWAT couldn''t help but make a remark.


    When Li Tou heard the questions from his subordinates, he was also very curious about what was to be transported. So he turned his eyes to the person in charge sent by the municipal government on the platform and asked him, "comrade, what materials are we going to receive? We don''t know anything, and we don''t have the bottom of our mind when we carry out the task. Can you tell us? "


    While saying this, Li took out a pack of crumpled cigarettes from his arms, carefully took out one, and threw some meat to the person in charge.


    After taking the cigarette thrown by Li Tou, the other party''s eyes lit up obviously. He looked around and saw that all the special police and staff under Li Tou were on the platform. Then he took two steps to Li Tou and said to him, "borrow a fire."


    Li Tou took out a lighter from his pocket, helped the other party light a cigarette, watched the other party enjoy a puff, waiting for him to speak.


    "This time it''s oxygen equipment." Smoking, the person in charge of the city government lowered his voice and told Li Tou what the equipment was.


    "Oxygen plant? Does it need to be so careful? " When Li Tou saw that the person in charge of the municipal government was so careful, he lowered his voice and asked his doubts.


    For men, a lot of times, smoking together can be like a good friend for many years.


    The person in charge of the municipal government heard about Li Tou''s problem. He didn''t know whether it was the role of cigarettes or whether it didn''t matter to Li Tou. He vomited a cigarette ring and said, "don''t you understand? It didn''t need to be so careful before, but now it''s the end of the world! "


    "What does this have to do with eschatology?" Li Tou still didn''t understand it, but he still knew how to put it into practice: "if it''s grain or something, I can understand this oxygen making equipment I really want to ask for advice. "


    "I don''t dare to ask for advice, that is to say, it''s just a little bit more information than you''ve come into contact with." The person in charge of the municipal government took two more puffs of smoke, and then explained: "the primary school students all know that oxygen is produced by plants, but now the vegetation and other things have been burned up by the previous fire, and there is no sun, so photosynthesis is impossible. This oxygen..."


    At this point, naturally, there is no need to go on, because Li Tou is already sucking in air conditioning.Even if we don''t understand the importance of oxygen, we all know that people need to breathe. If there is no oxygen, people will suffocate, let alone mention it.


    The words of the person in charge of the municipal government obviously made Li Tou realize the importance of this batch of equipment, but what he still didn''t understand was why they wanted the special police team to escort them.


    So Li Tou asked the person in charge of the city government in a low voice: "what''s the name of brother? How did such an important thing make our SWAT team come? It''s not too much to move the army, is it


    "My name is Li. Just call me Xiao Li." The person in charge of the municipal government took a look at Li Tou and saw that he was older than himself and didn''t put on any airs: "I''m not sure about this, but the municipal government should have some ideas about this batch of equipment. It''s said that the equipment is not enough for each refuge."


    "Ah? It can''t be true? Is there not enough of such an important thing? " Li Tou could hardly suppress his surprise.


    "It''s not enough. All the equipment was sent in two batches. This is the first batch." The person in charge of the municipal government explained to Li Tou: "but since there are two batches, there must be a priority. No one wants to wait for the next batch, right?"


    "This is also..." Li Tou wanted to say something else, but the sound of the train came from the distance.


    A little white light accompanied by the sound of rolling wheels broke through the darkness and came slowly and quickly from a distance.


    Everyone on the platform was shocked and the train carrying the equipment arrived.

 Chapter 66

    Due to the impact of natural disasters, the original railway transportation system was seriously damaged. Although the railway line has been restored to operation after the disaster regardless of the cost of rush repair, the original electric locomotive is obviously unable to run. After all, most of the high-voltage power supply network along the line was destroyed by the previous fire and impact.


    So now the railway running in Yanguo are all old steam locomotives.


    Although the speed is not as fast as the electric locomotive, but in this case, this kind of coal-fired old locomotive is much more reliable than the electric locomotive, and the steam locomotive can run everywhere with a coal car, without the support of the high-voltage power supply network along the line, and the maintenance requirements are also much smaller.


    The railway does not mean that it will be finished when the tracks are laid. The smooth railway transportation depends on the maintenance of the railway. Now, it is not as difficult as before to maintain the normal use of the tracks. It is not easy to ensure the transportation of important materials.


    Hearing the roar of the train, Li Tou and the person in charge of the municipal government all adjusted themselves quickly. One quickly smoked out the cigarettes in his hand, threw away the cigarette ends and prepared to receive materials, while the other signaled his subordinates to raise their vigilance.


    With the sound of the train wheels, a locomotive spewing white steam appeared like a monster from the darkness. The driver sounded the siren, and the harsh sound cut through the night sky, just like the roar of some giant beast.


    Driving out of the darkness is indeed a monster. It is a giant vehicle wrapped in steel. The front of the vehicle is sprayed with rich white steam, which makes the whole platform filled with white fog and blurs the vision.


    Behind the front of the car spewing white steam, there are iron and steel "bodies". These cars are covered with heavy metal armor and full of shooting holes. Needless to say, there are turrets on some of the cars, which are very ferocious in the fog.


    "Is this an armored train?" Li Tou is quite knowledgeable and naturally knows something that he has only seen in war movies.


    This was something that appeared in the first World War and the Second World War. Trains were armed with armor and artillery and used as mobile fortresses and firepower strongholds. Relying on the mobility of trains, the safety along the railway could be effectively guaranteed during the war, and they could also be used to transport important materials as they are now.


    But this kind of armored train also has a big disadvantage, that is, it relies heavily on the railway. As long as the railway track is damaged, this kind of armored train is powerful, but it can''t be destroyed.


    However, in the current situation, this kind of armored train can be used to transport important materials and ensure the safety of materials.


    "It''s really Where did you pull this out? " Looking at the armored train slowly entering the platform, Li Tou couldn''t help but vomit. Although he also saw that it should be a new one, the armored train itself can be described as old Dong.


    The person in charge of the municipal government also felt that he couldn''t bear the picture. He had come to the railway station several times before to receive materials, but those times were ordinary coal trucks and trucks, not as exaggerated as armored trains.


    Looking at the turrets and shooting holes on the armored cars, he was also shocked by the momentum shown by the steel monster.


    Compared with Li Tou and the person in charge of the municipal government who was shocked by the armored train, Qin LAN saw the steel monster driving out of the darkness, and felt only a sense of magic.


    "Is this the Steampunk ah Hsin used to talk about?" Qin LAN can''t help muttering, the scene in front of her can only think of this adjective.


    Without the end of the sun, an armored train spewing steam and wrapped in steel, if it wasn''t for the reality after the end of the day, Qin LAN would really think it was a scene in a movie before the disaster.


    But unfortunately, this kind of scene that would have been seen only in movies or historical documentaries has become a reality in the world after the end.


    At present, the temperature is gradually decreasing, and June is comparable to December. Steam locomotives are more practical than electric locomotives in some aspects, especially when the railway power system has basically been reimbursed.


    At present, except for a few electric locomotives on railway lines, most of them have been replaced by steam locomotives.


    As for why the armored train is pulled out of the history, on the one hand, it is to ensure the safety of the important materials transported, on the other hand, it is also to deter those who feel that the times have changed and can carry forward the traditional art of railway guerrilla. Don''t take risks.


    So far, destruction of Railways and robbery of material transport trains have taken place everywhere. It is also a practical need to use armored trains to transport these important materials.


    Most of these people came from villages and towns. Before the disaster, they escaped by relying on the village shelters. In order to obtain materials after the disaster, it is not impossible for groups to destroy the railway and intercept trains.


    Most of these shelters were built temporarily three months before the disaster. Most of the people who lived in the same village or nearby villages had relatives. Gang crimes were common.In the past, this kind of thing was not uncommon in the country of Yan. It was illegal to set up road cards on roads to collect fees, create accidents, let trucks overturn and snatch goods


    Usually, it''s the whole village that commits crimes. It''s not responsible for the public because of the law. Even if the police go to many places, it''s useless.


    As for conflicts with the police, although not too many police cars are overturned, they are not individual cases.


    Before the disaster, of course, these people did not dare to destroy the railway and derail the train, but for the train stopped on the railway, they never gave up the idea of stealing from the train.


    Even before the disaster, these people became more unscrupulous after the disaster. So it''s no wonder that the government of the Republic of Yan used armored trains to escort important materials. After all, every car was equipped with equipment related to hundreds of thousands or even hundreds of thousands of people''s lives.


    Under such a heavy task, the armored trains received military orders, and the soldiers were all carrying out the tasks, and the military orders meant that people would be killed, but they would really be killed.


    The heavy armored train braked and stopped on the platform.


    When the car door opened, a group of soldiers with guns and live ammunition came down first. They quickly spread out the troops on the platform to guard. Then an officer with a document in his hand came out of the car.


    Seeing the officer appear, the person in charge of the city government rushed to meet him.

 Chapter 67

    "Hello, comrade! Our department has been ordered to escort three sets of large biological oxygen generators and five sets of medium biological oxygen generators. The goods are in good condition. Please accept them! " The officer saluted the person in charge of the municipal government. After checking the identity of the other party, he handed him the document in his hand.


    Looking at the uniform actions of the officers, the person in charge of the municipal government was relieved after taking over the documents. The pressure on these soldiers who are on duty is too great.


    Fortunately, after the documents were handed over to him, the officer in front of him restrained some momentum, which made the person in charge of the municipal government feel less pressure and turn around to let the people he brought unload.


    Li tougang has just learned from the person in charge of the municipal government how important the equipment is. At this time, he saw that the staff of the municipal government began to unload the car, so he looked inside the car curiously to see what kind of equipment is related to the life and death of more than 200000 people in the city.


    But to Li Tou''s disappointment, all the boxes that came down from the carriage were tightly sealed, so that people could not see what was in the boxes.


    However, when Li Tou watched the equipment coming down, he also understood that the person in charge of the municipal government had told him that the equipment was not enough.


    Needless to say, we all know that the three sets of large-scale equipment must be given to the three major shelters. After all, there are more than 100000 people in total, and no mistakes can be made.


    And to put it cruelly, as long as these three shelters are preserved, even if all the other shelters in the city are lost, at least half of the population will still be preserved.


    But even if only one of these three shelters is in trouble, tens of thousands of people will die.


    If all the three major refuges in the city are lost, even if one of the remaining small refuges is not lost, only half of the population will be left.


    I believe the municipal government knows how to choose as long as it has a good brain.


    Except for large-scale equipment, there are only five medium-sized equipment.


    This problem is not only discovered by Li Tou, but also noticed by Qin LAN, who just heard the dialogue between Li Tou and the person in charge of the municipal government.


    In addition to the three major refuges, there are six large-scale refuges in the city, including the city government, the police station, the water plant, the thermal power plant, the lakeside community, and the Institute of technology.


    In addition, there are other small-scale shelters in the city. As a special police officer, Qin LAN knows this. These small shelters add up to 11.


    And this does not include private shelters such as Chen Xin and Mo Qingyan. Of course, there is no need to include these private shelters.


    Apart from the three major refuges, there are so many refuges in the city, and there are only five sets of facilities Even six larger shelters are not enough.


    Aware of this, Qin LAN finally understood why the city government didn''t use the armed police force to escort and changed to the special police team.


    The number of armed police stationed in the city is not large. Although it is a detachment, in fact there are only three squadrons stationed in the urban area, with a total of more than 400 people.


    So even before the end of the day, the people of the municipal military division and the armed police were assigned together, and their shelters, even if they were the families of the staff of the listed military division, were less than 3000 in total.


    More than 400 of them are not local people because of China''s armed police system, and their families are not in this city, but in other places.


    At the beginning of the construction of the three refuges, the designed population was 50000. Although the city government and other six refuges designed to accommodate different populations, they all now live in at least 10000 people, such as the police station, and 20000 people live below.


    Together, that''s 240000 lives, and it''s the main survivor of the city now.


    Three sets of large equipment supply three large shelters, five sets of small equipment and six shelters are not enough.


    If the armed police are allowed to escort and distribute a set of equipment to the armed police, there will be only four sets of small equipment at the disposal of the municipal government, which will make the distribution problem that is difficult to choose even more difficult.


    In particular, we need to consider the time when there is a hospital with all medical resources in the city.


    If it''s a disaster, the municipal government doesn''t need to consider this at all, because whether the armed police or the army, their duty is to protect the people first.


    But now, the city has to think about all the possibilities.


    "Load the truck!" Seeing that all the equipment had been unloaded and the person in charge of the municipal government had checked it, he called for people to start loading.


    At this time, Li Tou also mentioned twelve points of caution, and told all the special police, "everyone, pay attention! Step up the alert! "


    The atmosphere on the platform suddenly became more tense, and the workers in charge of loading also speeded up their actions.


    Fortunately, a few sets of equipment and things are not much, one by one big box was quickly loaded on the transport vehicle specially prepared by the municipal government.


    The officers on the platform saw that the materials had been transported away, so they saluted the person in charge of the city government and Li Tou, and led the soldiers back to the armored train. The door closed, and the steel giant that had not been put out sounded its whistle again and drove out of the platform slowly.


    And Li Tou and the person in charge of the municipal government also walked out of the platform together, ready to escort materials to leave.Qin LAN and other members of the special police force kept alert and quickly evacuated the platform.


    Outside the station, every material transport vehicle is escorted by a special police vehicle. Except for a large set of equipment left for the shelter of the railway station, other equipment has to be transported away.


    When he got on the bus, Li Tou ordered the motorcade to set off. He felt that the car was moving. The person in charge of the city government relaxed a little. However, he still couldn''t relax because the equipment didn''t arrive at the shelters.


    "Comrade, which shelter shall we send first?" Li Tou asked the person in charge of the municipal government. Although he accepted the escort task, he really didn''t know how the municipal government allocated this batch of equipment. When he made the action plan before, he also included the forward route of each refuge.


    "Go to the pedestrian street first, then the city government, the police station and the shopping mall." The person in charge of the municipal government replied to Li Tou, and also said which shelter the last set of equipment should be given: "the operation of the water plant and power plant must be guaranteed, and the last set of equipment should be transported to the first people''s Hospital of the city."


    "I see, everyone, be alert! Pay attention to the road condition at any time! " Li Tou nodded to show that he understood, and gave instructions to everyone at the same time.


    After receiving Li Tou''s instructions, all the people in the team raised their vigilance. Although it was dark outside the car window, they were still watching with wide eyes.


    As a sniper, Qin Lan''s equipment has a pair of night vision mirror, which allows her to see the surrounding situation clearly in the current environment.


    Naturally, her sniper became an important eye of the whole team at this time.


    Holding his own sniper gun, Qin LAN carefully inspected everything on the route of the motorcade and was on guard against any possible danger.

 Chapter 68

    The drizzle has been falling, neither getting bigger nor stopping.


    Although the protective clothing has a good effect of keeping warm, Chen Xin still feels a bit cool.


    "Hoo Hoo... " Chen Xin''s panting is a little rough. Although the protective mask can effectively block the harmful ingredients in the air, it also affects breathing.


    It was OK before, but now with Chen Xin''s breathing quickening after a long walk, he feels a little out of breath.


    Chen Xin wanted to find a place to sit down and take a rest, but seeing the rain and mud all over the ground, he decided to move on.


    After all, it''s just a little bit short of breath. Chen Xin had a similar experience when he traveled to Sichuan before. Just slow down a little.


    However, this also made Chen Xin doubt whether he really lacked exercise as Qin Lan said. When he went to Sichuan for tourism, he was panting because of the altitude reaction caused by the local high altitude and thin air.


    Is it true that when a professional network writer is not exercising these years, his physique has become worse?


    Chen Xin has such doubts. He can''t help wondering if he should get a human powered generator to put in the shelter. Stepping on the human powered generator when he''s free can not only generate energy, but also exercise.


    But just as Chen Xin was thinking about it, he suddenly stopped and looked up at the sky.


    The rain fell on the screen of the protective mask, leaving an ugly stain, but Chen Xin was still staring at the sky, looking at the thick dust clouds in the dark sky.


    "Damn it! It''s hypoxia! " Chen Xin''s brain is not stupid, he just subconsciously ignored this problem.


    Who cares about the oxygen we breathe all the time? I''m afraid it''s only when you''re really out of breath that you realize you need oxygen, right?


    When preparing for the construction of the shelter before the disaster, Chen Xin also subconsciously ignored this problem, just prepared oxygen cylinders in the shelter.


    But now, when he realized that he had encountered the problem of lack of oxygen, he realized that when the plants on the surface were destroyed by the fire and the sky lost its sunlight, the air we used to take for granted had become the biggest problem for survival.


    People need oxygen to live, any activity of the human body also needs oxygen to maintain, and the more intense the activity, the more oxygen consumption.


    Without natural plants for photosynthesis, oxygen in the atmosphere will gradually decrease with the consumption of surviving human beings.


    Unless the dust clouds in the sky disperse, the sun shines on the earth again, and new plants germinate for photosynthesis, otherwise, the process will be irreversible.


    If the surviving human wants to survive, they can only find a way to produce new oxygen.


    Chen Xin himself is not worried about this problem. There is a greenhouse in his refuge. Under the light simulated by the fill light lamp, all the crops will still carry out photosynthesis, which is enough to maintain his oxygen consumption at present.


    As for the official refuge, Chen Xin thinks that the state should take this problem into consideration. The only uncertainty is whether the state can solve this problem perfectly.


    After all, the state should consider all the survivors in the country, not one of the refuges.


    Common oxygen preparation methods include physical oxygen production and chemical oxygen production. Physical oxygen production is simply to collect oxygen in the air to use where oxygen is needed. Chemical oxygen production is to reduce oxygen from carbon dioxide or other raw materials containing oxygen to form new oxygen through chemical reaction.


    These two methods were widely used in oxygen production before the disaster, but in the present end, they are not so applicable.


    Physical oxygen production needs a lot of electricity, and only the original oxygen in the air is extracted. In the present environment where the oxygen content in the atmosphere is gradually decreasing, this method is not applicable.


    As for chemical oxygen production, although it has no disadvantages of physical oxygen production, it also has disadvantages, that is, chemical oxygen production needs to consume chemical agents, and the cost is high, so it is not suitable for large-scale application.


    Therefore, if the government wants to solve this problem, it can only take measures other than these two means to solve it.


    - - - - - - - - - - - - - -


    "the task has been finished at last!"


    After completing the escort work of oxygen equipment, the SWAT team returned to the shelter under the police station, and everyone relaxed.


    Although most of the special police officers did not know what the materials they were escorting were, they could guess that they were very important materials when they saw the armored train at the railway station and the situation of the escorting.


    So when escorting these materials, everyone was very nervous.


    Now that we have finally completed the task, we are naturally relieved.


    The group walked to the area where the SWAT team was. Although the task was not tiring, everyone was a little hungry under high mental tension.Although the food in the shelter is not very good, it is a happy fact to have something to eat after the mission.


    But now the food in the shelter is mainly emergency food reserved before the disaster, so although there is a canteen, it is only used to distribute ration food, and there is no fire for cooking.


    After all, fuel is precious now, so it''s a bit luxurious to cook.


    As for the greenhouses that have begun to produce mushrooms, and the artificially raised mice and bread worms, although these foods have gradually begun to appear in the recipes of the shelters, they are not so far as the Swat members can only eat them.


    "What do you have to eat today?" A special police officer hooked his friend''s shoulder and listened to him.


    "I think it''s fried mutton with scallion. Yesterday''s is shredded pork with Beijing sauce. It''s time to change today."


    The companion responded to his words. It sounds like the food is OK, but in fact, what they said was only the taste of self heating food.


    In the two months after the disaster, except for mushroom and mouse meat, we haven''t seen fresh food for a long time.


    On one side, another member of the special police broke in and said, "I think there should be cabbage soup today. Yesterday we came back with a box of cabbage! A whole box of fresh cabbage


    "No! It''s me and the pillar who carry it together. It''s two hundred jin! " When a special police member who also went to carry vegetables yesterday talked about the cabbages, his eyes were already bright.


    Not everyone knows about the news of fresh vegetables. When they learned about it, many SWAT members cheered excitedly: "Oh! I haven''t smelled cabbage for two months! "

 Chapter 69

    To be able to eat fresh vegetables temptation, so that the SWAT team to speed up the pace, like a real run to the canteen.


    The delicious smell of the long lost food diffuses in the air, which makes the special police members who rush into the canteen like a swarm of bees can''t help swallowing.


    They really haven''t smelled such an attractive fragrance for a long time. Although the taste and taste of self heating food are passable, how can self heating food compare with fresh food!


    In the dining hall, master Fu Jiubu picked up the frying spoon and set up a large tray on the table. Although the materials and conditions were limited, only induction cooker and small frying pan could be used, the master was still trying to make a large pot of delicious dishes and was loading them from the frying pan to the tray.


    In fact, when the chef was cooking, he was short of seasonings and other accessories. All he could put was oil and salt, but even so, the fresh food was still very attractive.


    Smelling the delicious smell and looking at the attractive dishes in front of us, everyone can''t help it.


    He rushed to the desk and looked at the dishes on the tray. While swallowing his saliva, he asked the master, "master, what''s the dish today?"


    "Fried rat meat with cabbage! Fresh cabbage and fresh mouse meat Master Fu seems to be afraid of these SWAT team members worried about the uncleanness of the mice, and specially stressed: "don''t worry, I have washed and peeled each of these mice, to ensure that there is no dirt and smell, and it tastes no different from chicken."


    Of course, mouse meat can''t be considered as a proper food. For master Fu, if he was asked to cook with a mouse before the disaster, it would be an insult to him. He could make a dish with a kitchen knife.


    But now it''s the end of the world. I don''t even mention pork, beef and mutton. I even want to take second place. Chicken, duck and fish have become very rare.


    Chickens and ducks may still be seen, but fish has basically disappeared, even if the city is close to yunmengze, which was originally the land of fish and rice in Dongting.


    Although there is a large-scale reform through labor farm in this city, the output of agricultural and sideline products can no longer be expected in this situation. The situation on the other side of the reform through labor farm is even worse than that in the urban area.


    So the mouse, which was once despised, has become a good meat.


    Of course, the SWAT team members also know the situation, so they will not dislike the master to make them mouse meat. However, the taste of cabbage fried mouse meat still makes the SWAT team members a little uneasy.


    Although the shelter has started to eat mice and mushrooms, the supplies of the special police force are still sufficient. In the past two months, they have eaten self heating food. They have not tasted the mouse meat, so they are afraid.


    But as long as two months did not eat the temptation of fresh food or let these SWAT team members with appetite to overcome the heart of that little resistance.


    "Master, give me one first! More food! " A special police member couldn''t help but took a plate from the side and handed it to master Fu.


    The master happily scooped up a spoonful of cabbage fried rat meat, bumped it and then put it on the plate. He scolded the special police member: "there are so many dishes. If I give you more, there will be less for others! And wash your hands before you eat! "


    "Ha ha ha! Do you hear me? Wash your hands The other SWAT members burst into laughter.


    Qin LAN felt everyone''s lively atmosphere, and she couldn''t help smiling. Since the disaster, we haven''t been so lively and happy for a long time.


    This made her happy, and she went forward, waiting in line with everyone.


    Qin LAN thinks that whether the food is delicious or not is secondary at this time. It''s the most important thing for everyone to be so happy.


    "It looks like the meal is worth it." In the corner of the dining hall, uncle Ding and another man in police uniform looked at the rare lively atmosphere in front of them, and they could not help smiling.


    "It''s really worth it. In the past two months, the atmosphere was too depressing and the morale of the team was very low. Now I can make everyone happy. My work as a political commissar is much better." Uncle Ding is sitting next to the political commissar of the SWAT team. The low morale and depressed atmosphere of the SWAT team worried him for a long time.


    Hearing the commissar say so, uncle Ding feels the same way.


    For the SWAT team, personnel training and weaponry are of course the top priority, but morale can not be ignored.


    If a person is in a state of depression and tension for a long time, his mood will collapse.


    No one can imagine the extreme behavior of a person with emotional breakdown, especially a specially trained SWAT with a weapon in his hand.


    "In that case, do you think the political commissar can make a decision about the exchange of materials with that private refuge?" Uncle Ding asked the political commissar, although he could decide this matter as a team leader, he still had to ask the political commissar''s consent: "or should the Party group hold another meeting?"


    The commissar pondered for a moment, nodded and said, "in principle, I agree with this matter, but I''d better go over it again at the Party group meeting. The more time it is now, the more we can''t talk about it, so as not to be gossiped. "Although it''s the end of the world, but now the national order and government institutions are still in normal operation, the procedure should go again.


    Uncle Ding didn''t have any opinions when he saw the political commissar say that. He knew that even if he went to the Party group meeting once, it would still be passed.


    Having talked about this topic, the political commissar suddenly asked Uncle Ding, "speaking of Lao Li, what equipment are they escorting today? So many people have to be mobilized. "


    "It''s the oxygen making equipment allocated to each refuge. Scientists predicted before the disaster that humans would face the problem of lack of oxygen after a meteorite impact." After reading the information sent by the municipal government, uncle Ding knew something about it: "it''s still confidential. Don''t talk about it outside."


    "Don''t worry, I know the weight." The political commissar also nodded his head seriously. He knew that if this matter was known by the ordinary people in the shelter, it would inevitably cause panic and even riots.


    However, while understanding the importance of the matter, the political commissar was somewhat curious and concerned: "it''s said that it''s allocated to each refuge. Has our police station allocated it?"


    "Yes, it''s being installed now." As the captain of the special police team, uncle Ding naturally knew about it. He explained to the commissar, "the whole set of equipment is installed in the central room of the air circulation pipe reserved before."


    "It used to be used for this? I said how to reserve such a large room and make it the same as a pool. " The political commissar suddenly realized that he finally understood what the place reserved in the refuge was for.

 Chapter 70

    Chen Xin, who discovered the oxygen problem, wanted to go back to his shelter, but after a rest, he felt that he had recovered a lot. After hesitation, Chen Xin still went towards his set goal.


    On the one hand, the problem of oxygen is not serious at present. Although there are symptoms of hypoxia, it is not very different from the altitude reaction caused by the lack of oxygen in plateau areas.


    Moreover, Chen Xin felt it carefully. The burden it brought was just that he was a little short of breath. As long as he didn''t walk too fast, he could still bear the current state.


    Since there won''t be a big problem, Chen Xin doesn''t want to waste his chance to search for resources. After all, the happy water of fat house he found before gives him great encouragement, and makes him hope and look forward to finding more resources in the supermarket he is targeting.


    However, when Chen Xin came to the supermarket through the dark street in the rain, he suddenly stopped and hid behind a corner, holding the cherry cut on his waist.


    The entrance of the supermarket in front is bright!


    Chen Xin quickly took out a telescope from his tactical pocket and looked at it carefully. He found that the light was flickering like fire, and there were figures walking around.


    This made him very surprised.


    Although the supermarket in front of us is a semi underground building, it was not transformed into a refuge because the area was too small to accommodate many people before the disaster.


    There are no other shelters planned by the municipal government nearby. Because the population of the surrounding communities is not too large, they have moved to the shelters in the urban area for centralized resettlement.


    In principle, there should be no one here.


    Is it someone who comes to search for resources?


    Chen Xin denied this speculation.


    If it''s people who come to search for resources, they don''t need to make a fire at all. They just need to search for resources with a flashlight.


    Although the torch may be ignited due to the need to save the use of flashlight, in that case, the light should be mobile,


    it will not be like now. Although it is swaying, the position of the light source is very stable.


    Survivors who did not enter the shelter?


    It''s very possible.


    Although before the disaster, the country has done everything possible to let people into the shelter, but not all people were killed.


    After all, there are a few who can build their own shelters like Chen Yu and Mo Qingyan.


    Most of the people stranded outside the shelter did not survive the first shock and disaster caused by the meteorite fall, but still some people survived and stayed in the wild.


    Qin Lan''s special police team and the police in the city actually have part of their duty to search for survivors and transfer them to shelters.


    In fact, there are many underground buildings in the city that can resist the disaster caused by the first wave of shock.


    The underground parking lot, underground supermarket, basement, and even some large buildings with solid structure can be used as shelters to resist the disaster caused by the first wave of shock.


    As long as we find such a shelter and store enough materials before the disaster, it is not difficult to survive.


    So are the people in this supermarket the survivors?


    Chen Xin doesn''t know, but he doesn''t want to risk contact with them.


    Compared with the survivors who can enter the national refuge in time, the survival conditions of these wild survivors are much more difficult.


    Although the living conditions of the shelters built by the state may be crowded, they still need to work in the shelters. At least the safety and food can be guaranteed.


    But the survivors in the wild are not so lucky.


    They may be able to find a safe place as a refuge, but in this environment, food is very difficult to get.


    They may be able to support themselves for three or five months with food reserves before the disaster, but it is not a long-term solution.


    In particular, the lack of drinking water will force them to venture out to find all the materials they can collect.


    At this time, Chen Xin, a person with good equipment, appears. It''s hard to guarantee that no one will see the money.


    Although novice Chen has both a knife and a gun, it''s better to do more than less. There''s no need. He doesn''t want to get into trouble.


    After recording the place, Chen Xin didn''t move on. Instead, he took out a pistol from his body and held it in his hand. After a long distance, he quickly turned and left.


    After returning to his shelter, Chen Xin put down his backpack, took off his protective clothing and face mask, and then sat down on the sofa in the living room.


    Before, Chen Xin felt shortness of breath outside, but after returning to the shelter, his condition improved a lot.


    Because of the relationship between planting greenhouse, the crops inside can still carry out photosynthesis with the help of supplementary light, and the oxygen content in the shelter is now significantly higher than that of the outside world.Adjust their own state, the gun and cherry cut back to the weapon cabinet, this is to check their harvest this time.


    Before Chen Xin arrived at the supermarket that might be occupied by the survivors, he searched a street, six small supermarkets and about 89 other shops, and found something useful.


    One of the shops is in hardware business. There are more than ten steel pipes and more than twenty small valves in the shop, which is Chen Xin''s biggest harvest this time.


    In addition, it''s just some miscellaneous gadgets, such as screwdrivers that burn only metal parts, and a package of files that burn but are in good condition.


    They are all things that can be used, but they don''t know what they can do for a while.


    So Chen Xin just gathered and sorted out the things he found, covered them up, and didn''t bring them back.


    He is going to drive again tomorrow to bring back everything he finds.


    As for the food, Chen Xin didn''t find it. It seems that it was cleaned up, leaving only the box of happy water and half a box of beer that Chen Xin found.


    The two pieces of soap found together with happy water and beer have been put in the bathroom by Chen Xin. This kind of daily necessities is not easy to handle now. It''s a surprise to be able to supplement them.


    After sorting out the materials, Chen Xin still uses the radio to contact Mo Qingyan after thinking about it.


    "Ingredients, what can I do for you? How did you contact me today? " Mo Qingyan feels a little strange about Chen Xin''s sudden call.


    "Long Niang, do you have any plants that can still carry out photosynthesis in your refuge?" Chen Xin didn''t care about Mo Qingyan''s question, instead, he asked her about plants.


    Although confused by Chen Xin''s question, Mo Qingyan answered his question: "plants? photosynthesis? I have a green plant box in my bedroom. How can you suddenly ask about the ingredients? "

 Chapter 71

    Although confused by Chen Xin''s question, Mo Qingyan answered his question: "plants? photosynthesis? I have a green plant box in my bedroom. How can you suddenly ask about the ingredients? "


    "The sky is covered by dust clouds and sunlight is lost. What do plants rely on for photosynthesis? Without photosynthesis, where does oxygen come from in the atmosphere? " Chen Xin''s voice is very insipid, just telling a fact, but it makes Mo Qingyan feel a thrill: "although 70% of the oxygen in the atmosphere comes from the marine ecosystem, even algae need sunlight to produce oxygen, and now there is no sunlight."


    "Do you mean there will be no oxygen in the atmosphere?" Mo Qingyan asks Chen Xin with a few panics.


    Although Mo Qingyan couldn''t see it, Chen Xin nodded: "if we lose the conversion of carbon dioxide by photosynthesis in the ecosystem, the concentration of carbon dioxide in the atmosphere will soon increase, while the oxygen content will continue to decrease. In addition, when the oxygen disappears and the oxygen content in the atmosphere is less than 10%, human beings should be suffocated. "


    "Ah! What shall we do then? " Mo Qingyan rushed to Chen Xin for help, and her tone was full of confusion.


    In the face of such planetary disasters or environmental catastrophes, there is no possibility for personal power to make any changes. After all, this book is just a slightly unorthodox science fiction, and it is not a fantastic novel that does not even talk about the basic laws of physics.


    "Growing grass is a solution to the problem." Chen Xin half joked, half seriously said one thing, and then explained: "since you have a green plant box, this problem is not difficult to solve. The oxygen required for a normal adult breathing needs about 10000 leaves of average size for photosynthesis. If you calculate a tomato with 250 leaves, you need about 40 tomatoes, covering an area of about 100 square meters It''s about 50 square meters. "


    At this point, Chen Xin laughed. It was the first time that he saw Mo Qingyan flustered. After laughing, he continued: "so as long as you build a large enough greenhouse in your basement, it will be enough to ensure the oxygen you need in your daily life, and also provide you with enough vegetables and food."


    "Ah! i see! So no wonder last time I went to your place with Anning, I didn''t feel bored at all! It''s not good ventilation, but you have plants producing oxygen! " When Mo Qingyan heard Chen Xin say so, she finally responded.


    At the same time, Mo Qingyan also realized that the air in her bedroom was good not because of the good ventilation, but because of the green plant box in her bedroom, where she had always turned on the fill light.


    But this situation makes Mo Qingyan have new worries. She asks Chen Xin, "ah Xin, what about the shelter? Tens of thousands of people live in government shelters. If they lack oxygen, will they all die? "


    "You can think of this problem. Don''t you think the country can think of it? The government should have a plan to deal with it. " Chen Xin is not worried about this. He does not think that the state will ignore this issue as much as he does.


    If there are so many experts and scholars in the country who can''t come up with a disaster response plan that can at least deal with most of the problems under the condition of three months'' early warning of the disaster, then these people are absolutely living on a diet.


    Hearing Chen Xin say so, Mo Qingyan also finds that she is worried about nothing. If there is no way to deal with this kind of catastrophe involving all people, she can do nothing by herself.


    However, Mo Qingyan still asked Chen Xin, "all the countries have taken refuge from the government. What about our private shelters? Xin, it''s not a big problem that you have a greenhouse. What should I do? No, I really want to take Anning and Qingxin to your place, right


    "It''s not very difficult to solve this problem. If I realized this problem in advance, a few lights and water tanks could solve the problem before the disaster, but now..." Chen Xin hesitated for a moment, but still said to Mo Qingyan, "you can try to get a large water tank to raise algae. The metabolism of algae is very fast. Under the condition of ensuring the light, it can release oxygen quickly, which is more efficient than plants.


    But it will consume a lot of water and electricity to provide light, but now the city government is still supplying water and electricity, so it''s OK to ensure the survival needs of the three of you. "


    "Algae? How to do this? " When Mo Qingyan heard Chen Xin say so, she put down her worry and asked how to raise algae.


    "Use grill board to keep the surface moist, and then use fill light to shine continuously." Chen Xin and moqingyan said, while turning on the computer, looking up the information inside.


    Chen Xin remembers that when he was writing a book before, he found a document about the German ecological experimental building, which introduced that the German people used algae to make the biological facade of the building, cultivated biomass through photosynthesis for biogas reaction, and then generated carbon dioxide through biogas power generation to supply the biological facade for recycling.


    The main reason for the establishment of this cycle is that sunlight promotes the photosynthesis and mass reproduction of algae. Now, without sunlight, we can only make up for it by using fill light.


    But in this way, biogas power generation with biomass produced by algae is certainly not enough, and additional energy consumption is needed.Fortunately, Mo Qingyan doesn''t cut off the water and power supply. As long as the water and electricity supply is guaranteed, she can still guarantee the survival needs of Mo Qingxin and Ding Ning.


    Chen Xin explained in detail to Mo Qingyan the principle of the whole system and how to make it. Mo Qingyan also recorded what Chen Xin said and planned to build a set of such equipment in her own refuge to produce biological oxygen.


    "Thanks a Xin! If you didn''t remind me, I''m afraid I would have suffocated to realize this problem. " Mo Qingyan said thanks to Chen Xin, not forgetting to say: "don''t you miss my wine? I''ll give you a box of Kim rum later, and I''ll exchange the information with you. "


    Hearing Mo Qingyan say so, Chen Xin can''t help feeling a little surprised: "is it necessary to calculate so clearly with me?"


    "It''s said that if we''re brothers, we''d better be clear." Although Mo Qingyan said so with a smile, she was very serious: "although you don''t mind me taking advantage of you, ah Xin, now in the end of the world, we are still clear enough to avoid conflicts."


    After hearing Mo Qingyan say so, Chen Xin didn''t raise any objection. He just talked with her again about whether to tell the people in the survival group. Then he said to her, "by the way, long Niang, please help me talk to a LAN, that is, I found a survivor in a supermarket in the direction of the high-speed railway station..."

 Chapter 72

    On the road to the outskirts of the city, a black armored police car was moving.


    Sitting in the car is a team of armed special police, they are on a mission to the outskirts of the city.


    Chen Xin found the supermarket where there might be survivors. Instead of exploring or contacting it himself, he told Qin LAN about it and asked the police to deal with it.


    For Chen Xin, although he has no way to get any benefits, there is no danger.


    Moreover, compared with his own personal contact with those survivors in private, whether the other party is desperate or innocent, the police are obviously more capable than him.


    "Repeat the main point of this mission! This is an old supermarket that may be occupied by survivors. It''s not sure whether the survivors have weapons or what kind of attitude they have, so everyone must be on guard against the same thing that happened last month! " On the bus, the group leader in charge of leading the team was giving a serious lecture.


    And hear his words, the car''s several SWAT team members face changed a lot of grim.


    What the team leader mentioned is that more than a month ago, a group of ordinary gun police officers on patrol found an underground supermarket occupied by survivors in the urban area. One of the survivors attempted to snatch the gun from the police officers, causing three deaths and four injuries to the survivors and one minor injury to the police officer.


    At that time, the police officers in charge of patrolling found the survivors. When they contacted the survivors, they relaxed their vigilance because they were pitiful. One of the survivors with criminal record saw that the police officer had a gun on him, so he had the idea of snatching.


    In the process of robbing police officers with guns, a fire broke out, leading to the death of one survivor, and then triggered violent conflicts between the police officers and the survivors. Finally, a total of two survivors died on the spot, five were injured and sent to hospital, and one of them died of ineffective rescue.


    Although heavy allusions should be used in troubled times, it is not a happy thing for the police whose duty is to protect people''s lives and property to point their guns at the people they are supposed to protect.


    Although when the survivor snatched the police officer''s gun, he had become a criminal from the people.


    The team leader''s reminder made the Swat members in the car feel awe inspiring. In troubled times, it is necessary to use heavy allusions, but not everyone can immediately change their thinking and mentality, and point a gun at the survivors who were just ordinary people in cold blood.


    In particular, before the disaster, the laws of the Republic of Korea rarely allow police officers to shoot criminals, and the police regulations restrict police to shoot to death.


    For ordinary people, in the face of this kind of disaster, they are more worried, uneasy and worried about their own future and survival.


    The kind of people who can immediately change their mentality on the second day of disaster, become decisive and cold-blooded and merciless, are not those who have a hidden heart to kill before disaster, have a tendency to commit violent crimes, or are extremely selfish.


    Extreme environment will give birth to extreme emotions. When people can survive, not everyone will first think about how to kill their peers and seize their survival opportunities.


    At the moment when the national government still exists and the government departments still operate normally, the police will still perform their duties as before the disaster to ensure the safety of people''s lives and property.


    However, compared with before the disaster, their disposal methods will change somewhat.


    It''s like now, when the armored car arrives at the door of the underground supermarket Chen Xin found, and it turns out that there is a fire coming out, these special police officers don''t get out of the car to get in touch as they used to. Instead, they directly sit on the armored car and shout through the horn of the car to let the people out of the supermarket.


    Police door, no doubt scared the supermarket survivors.


    This is just a group of ordinary survivors. They didn''t get into the shelter in time before the disaster, but fortunately, they found a fairly solid basement, hoarded a lot of food and water, and survived the disaster.


    Although in the process, their number has decreased from a dozen to only a few now.


    There is no conspiracy or dark human nature in the process of downsizing. It''s just that those people didn''t survive.


    After a series of disasters, such as fire, cooling, acid rain, and even meteorites falling down every two or three days, only a few of them died. It''s lucky that they didn''t die without food and clothing.


    But it also turned the survivors into terrified quails.


    The first basement helped them through the fire after the impact of the meteorite, but the smoke choked two elderly people.


    Then an acid rain came down and the basement was flooded. One third of their food reserves were soaked in soup and had to be transferred to a small building which was still in good condition.


    They stayed there for a while, but a meteorite as big as peanuts smashed half a small building, so they had to change places.


    In the process, three girls caught in the rain had a high fever, two did not survive.When the meteorite hit the small building, there were two people in the half of it. When they went to save people, they only found one leg and three arms.


    As for their food and water reserves, they also lost everything until they found the supermarket.


    Most of the goods in the supermarket were wiped out before the disaster, but they still found some less edible food left in the supermarket warehouse.


    This let them finally lucky survived, until Chen Xin found out, and then called the police.


    "Did anyone come out and say something? We''re from the city special police team. We''re here to learn about the situation. Don''t be afraid. If you need help, we can help you. " SWAT did not go in, but still in the supermarket at the door with a loud speaker inside shouting.


    At this time, in the supermarket, a group of frightened survivors are holding weapons transformed with steel pipes, mop handles and other things. Their disheveled heads and dirty faces are shaking as if they were just rolling in the mud. Several survivors who look like girls are shaking into sieves.


    The survivors who have not seen the sun for two months are short of food and clothing, and even have difficulty in taking a bath and washing their face, which makes their spirit collapse long ago.


    At this time, in the face of the police shouting outside, these survivors are too scared to speak, and the supermarket door is more like a bloody mouth in their eyes, as long as they go out, they will be eaten.

 Chapter 73

    The special police yelled for a long time, but there was no response from the survivors in the supermarket, which made them a little strange.


    The fact that there was a fire at the door of the supermarket confirmed the information they had. At least there were signs of survivors'' activities.


    But after they yelled for a long time, the people inside were just like the criminals who resisted stubbornly. There was no movement at all. No one came out to reply and no movement was made.


    If not for the fire at the door, the Swat even thought that the people inside had escaped.


    "Chief, what shall we do now?" A special police team member looked at the supermarket which was still motionless and asked the team leader.


    The team leader frowned and looked at the supermarket in front of him. He was also in a dilemma.


    The supermarket in front of us is not a stronghold occupied by criminals, but a refuge for a group of survivors.


    Although they have not responded, it is impossible for the team leader of the operation to order the Swat members in the car to attack like the criminals.


    But it''s not a way to spend it. It''s not to say that we can''t afford it. It''s not like we''ve been arresting criminals for more than ten hours before.


    For these specially trained police officers, it''s no trouble waiting for more than ten hours in an armored car.


    The key is that they are not here to catch the prisoners now. They may be survivors who have lived outside for two months. They are likely to be in urgent need of help.


    After biting his teeth for a long time, the team leader decided to take people in.


    "Gangzi, Fengzi, and Gangqiang, you three take your equipment and follow me in. The others are on guard." The team leader ordered three team members to work with him.


    The armored police vehicle they came with a total of 10 seats. In addition to the driver and the commander of the operation, it also carried a sniper, an observer and six commandos.


    But today they didn''t bring snipers, only six SWAT team members, operation team leader and driver.


    The four men were equipped and ready to enter the supermarket.


    Called Gangzi, the commandos hold riot shields in one hand and police pistols in the other. They squat forward carefully.


    Behind the team are Feng Zi and gang Qiang, both holding assault rifles for the police, one in front of the other to provide cover for him.


    The operation team leader also follows Gangzi with a riot gun, responsible for commanding, providing support and negotiating with survivors.


    The four people in the group were walking slowly. As the group leader moved forward, he told the three people around him: "try to avoid conflicts, and give priority to uniforms. If you can''t shoot, you can''t shoot."


    "Yes The three members of the special police force all answered, and at the same time, they also raised their vigilance. They observed the surroundings more carefully, hoping to identify the survivors as much as possible and avoid accidental injuries.


    Although the police equipment has tear gas guns, which are non lethal equipment, and they also carry them, before confirming the identity of these survivors, the operation leader does not want to risk the lives of his team members.


    Although he made the judgment that the supermarket might be a survivor, it could not rule out the possibility of danger.


    Survivors in a stress state may be quite aggressive. Tear gas gun, a non lethal weapon with no lethality, is difficult to stop in this case.


    As for possible danger or ambush, two assault rifles are enough to deal with emergencies in this environment.


    But when they entered the supermarket, they saw a few people with simple sticks as weapons, huddled in the corner, terrified, looking at their survivors, the team leader knew that he was worried in vain.


    These survivors are really in a state of stress, but their physical conditions no longer allow them to make aggressive behavior, and they don''t look like they have the ability to attack.


    However, the chief of the operation did not relax his vigilance, and carefully approached the survivors together with the three SWAT team members.


    "Ah One of the survivors didn''t know if he was scared or what, but suddenly yelled, waving the steel pipe in his hand, he dashed at Gangzi with the riot shield.


    Gangzi quickly blocked with a shield, at the same time, the pistol in his hand also pointed at the survivor who suddenly went crazy.


    However, Gangzi didn''t shoot. He just took back his arm holding the shield. After holding the shield tightly, he bumped into the survivor with a cushion step and directly knocked him to the ground.


    The rest of the survivors were also frightened by the sudden situation. They immediately grasped the weapons in their hands and wanted to attack.


    But at this time, there was a sudden gunshot, which made them shiver and froze.


    A shell still steaming fell to the ground, making a clear crash sound.


    Seeing that the situation was under control, the team leader put down his shooting hand and put the pistol back into his waist.


    And Fengzi and Gangqiang behind him rushed up. One helped Gangzi hold down the survivor on the ground, while the other also pointed a gun at the group of survivors and yelled to them, "lay down your weapons!"Frightened by the sound of gunfire and shouts, the survivors have shaken into a sieve, and their sticks are almost unconsciously thrown to the ground.


    Seeing the survivors lay down their weapons, the team leader breathed a sigh.


    Finally, it was "peaceful" settlement of the matter.


    The survivors were sent to the shelter of the first people''s hospital.


    This is the only hospital still in operation in the city. Of course, most of the medical staff in the city are concentrated here. Other medical staff are stationed in several other shelters in the form of medical teams to provide medical services for the shelters.


    However, before the disaster, all the medical resources of the three people''s hospitals in the city were concentrated here, and became the only hospital in the city after the disaster.


    The survivors, who had been in the wild for two months, were in poor condition. They had to be sent to the hospital first for examination and treatment. After their mental and physical recovery, they could be considered to be transferred to other shelters.


    For the survivors, the doctors in the hospital have been used to their condition. This is not the first group of survivors in two months.


    After a whole process of sedation, cleaning, disinfection and examination, the doctors also found out the physical condition of these survivors. Except for individual special cases, these survivors are basically the same malnourished. After a few full meals and hanging a little glucose, they can basically recover.


    As for after The psychiatrist will guide them, and when the state slows down, the police will send them to a shelter.


    Now all the shelters are under construction, and there is a shortage of manpower.

 Chapter 74

    After learning that there would be oxygen problems, Chen Xin paid more attention to his own greenhouse.


    This is not only a place to provide him with food, but also the oxygen he needs to survive.


    If people don''t eat, they will die in about seven days. If people don''t drink water, they can last for about three days.


    But if you don''t breathe, you''re gone in ten minutes.


    There is no need to emphasize the importance of oxygen. Naturally, the importance of planting greenhouse which can provide oxygen is also greatly improved.


    Fortunately, Chen Xin has upgraded the planting greenhouse once before, and now not only the planting area has increased, but also the number and efficiency of fill lights have improved a lot.


    As long as it can maintain the operation of the planting greenhouse, even if the outside world is really cut off, the planting greenhouse is enough to provide him with the oxygen needed to survive.


    But this is not without hidden dangers, Chen Xin is not with planting greenhouse, there is no worry.


    Only relying on the light cooperation of plants to maintain the oxygen circulation in the confined space has been done for a long time. Even in those years, the Federation carried out a famous Biosphere 2 experiment to build a self-sustaining ecosystem.


    Unfortunately, these experiments failed.


    Plants can provide enough oxygen in a closed environment, but only if there is enough light.


    Once entering the night, photosynthesis stops, and the oxygen needed by plants and human beings will soon exhaust the limited oxygen in the confined space.


    Not only can the confined space not maintain such oxygen circulation, but also the biosphere No.2 laboratory, which was built with hundreds of millions of dollars of federal investment in that year, with a perfect artificial ecosystem, can not do the same thing.


    In the Biosphere 2 experiment, bacteria consume a lot of oxygen when they decompose the organic matter in the soil, but the released carbon dioxide is absorbed by the cement in the building, breaking the oxygen cycle and reducing the oxygen content in the air, which can not meet the needs of human survival.


    Of course, the solution to this problem is very simple.


    In the natural environment, because of the difference between day and night, plants can not maintain 24-hour continuous photosynthesis. In addition, plants need to consume oxygen to breathe, so they can not maintain the oxygen circulation in the confined space.


    But in the unnatural environment, this problem is not difficult to solve, that is, the use of fill light, to provide 24 hours of uninterrupted light for plants, to promote plants to maintain uninterrupted photosynthesis.


    If the plant carries out photosynthesis 24 hours a day, it can provide oxygen not only for its own breathing, but also for the survival of human beings living together.


    Only in this way, the consumption of energy will be greatly increased.


    Now is not before the disaster, with the sun this almost unlimited super large sustainable energy to provide the earth with a continuous stream of light and heat.


    Before the dust cloud blocks the sunlight, people can rely on the sun to enjoy its abundant energy, whether it is photosynthesis or solar power generation, which does not require additional energy input.


    But now that human beings have lost sunlight, they can only rely on the energy provided by the earth itself.


    Coal and oil, the most precious resources provided by the earth for human beings, are also the main ways for human beings to obtain energy.


    For the last generation of mankind, these two kinds of traditional energy have become the key to protect human survival.


    In particular, coal resources, whether heating or power generation, easy to use, easy to mine coal has become the most important material indispensable to human beings.


    However, for Chen Xin and his refuge, the main use is still gasoline.


    Just maintain 24 hours of uninterrupted light to ensure the production of oxygen in the greenhouse, and the consumption of gasoline for power generation will be greatly increased.


    It''s not that Chen Xin doesn''t want to use more efficient and reliable diesel, but that diesel will condense when the temperature is below zero, making it inconvenient to use.


    Although high-grade diesel can solve this problem, the price of high-grade diesel is higher than that of ordinary gasoline.


    After all, even if it is - 35 diesel, it can only be used at - 14 ¡æ to 29 ¡æ. Compared with the freezing point of ordinary gasoline at - 35 ¡æ, the advantage is not obvious.


    As for the higher grade - 50 diesel, it''s much more expensive than ordinary gasoline.


    When he first entered the shelter, Chen Xin only needed 10 liters of gasoline a day to generate electricity, which could meet all the power consumption. After upgrading the planting greenhouse, his daily fuel consumption was 20 liters. Because of the - 10% lighting time provided by the system upgrade, he only needed to irradiate the plants for about 12 hours a day.


    Now, if the greenhouse is kept in light for 24 hours, the fuel consumption will double, that is to say, Chen Xin will consume 40 liters of gasoline a day.


    That is to say, the gasoline that Chen Xin prepared at the beginning can last for one year, which is probably only enough for three months.


    And long time uninterrupted use of the generator, will also cause wear and tear to the generator, accelerate the damage of the generator."It''s time to upgrade the power generation system." Chen Xin rubbed his forehead and calculated his gasoline consumption. He decided that he had to upgrade the power system of the shelter.


    Otherwise, unless he can continue to get a lot of gas from the SWAT team to maintain consumption, he will face the situation of running out of gas.


    Just how to upgrade the power system? Simply increasing the output power of the generator is meaningless, because the energy is conserved, and increasing the output power only means consuming more fuel.


    It''s a feasible way to improve the efficiency of the generator, but it won''t play a big role. After all, saving 5% - 10% energy sounds like a lot, but when it comes to the actual consumption, it''s nothing more than delaying the days when the fuel is exhausted for a few more days.


    So the most appropriate way is to make the shelter self-sustaining, energy consumption and the output of the shelter balance, forming a cycle.


    Thinking of this, Chen Xin naturally thinks about the algae circulating oxygen generator he told Mo Qingyan.


    This system can produce oxygen and algae biomass, not only can provide oxygen, but also can be used to produce biogas for fuel cell power generation.


    Now that Chen Xin can extract groundwater, water resources are no longer a problem. Moreover, the consumption of water resources for algae cultivation is not large. In addition, it can be recycled. Chen Xin is not worried about the problem of water resources.


    As for the problem of carbon dioxide, after the whole system is put into operation, the carbon dioxide generated by biogas combustion can be collected to supply algae for photosynthesis consumption. If it is not enough, the carbon dioxide in the air is also a supplement.


    After all, Chen Xin''s refuge is not a completely closed ecological experimental cabin, which can be replenished with the help of external resources.


    The only problem is power consumption.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 75

    To solve the problem of power consumption, either Chen Xin''s oxygen generator can generate enough biomass for biogas power generation to meet his own consumption, or Chen Xin will continue to upgrade the power system of the current refuge, hoping to upgrade it into a more self-sustaining power system, such as a nuclear reactor that can operate for decades.


    The first option is naturally impossible because of the conservation of energy.


    If the biomass produced by the oxygen generator can be used for biogas power generation to meet the system''s own consumption, isn''t it a perpetual motion machine?


    So the way to solve the problem is to continue to upgrade the system, and to upgrade to energy saving and upgrading.


    It''s just that Chen Xin has checked his generator and power system. Among the system upgrade options, there are only two upgrade options: improving the working efficiency of the generator and improving the energy saving rate of the whole power system. It''s impossible to upgrade it to other types of generators for the time being.


    However, this is not absolute. When Chen Xin upgraded his protective clothing, he provided a tactical poncho to make the protective clothing more functional and tactical camouflage. He felt that if he could provide other power generation methods, he could integrate them into the power system.


    "If I integrate biogas power generation into the power system, with gasoline generator as the main force and biogas power generation as the auxiliary, the two methods can supply power at the same time..." Thinking of integrating other power generation methods into the power system, Chen Xin quickly took out a pen and paper for calculation.


    "at present, the consumption of planting greenhouse can only be maintained by 20 liters of gasoline consumed by the generator every day, and the consumption remains unchanged..."


    "Planting greenhouses can meet my own oxygen consumption when there is light, and there is surplus output But considering the overflow of the ventilation system and the oxygen consumption after turning off the lights... "


    "In the case of keeping the light time unchanged for 12 hours, without considering the existence of external oxygen, the oxygen produced by planting greenhouse can maintain my consumption for 16 hours..."


    "Prolonging the illumination time and increasing the oxygen output can provide the oxygen I need for 24 hours, but at least more than five hours of illumination per day will increase the gasoline consumption from 20 to 30 days..."


    "If we build the algae cycle oxygen generator, the power consumption is less than that of maintaining the greenhouse for a long time. With the power supplement brought by biogas power generation, we only need to increase the gasoline consumption by 5 liters every day..."


    By listing all the data for calculation, Chen Xin can easily calculate the results.


    Looking at the results of his calculation, Chen Xin touched his chin and obviously built an algae circulating oxygen generator that he told Mo Qingyan, which is the scheme with the least consumption at present.


    Moreover, after Chen Xin built such an oxygen generator, he could upgrade the oxygen generator through the system to improve its oxygen production efficiency, biomass output and biogas reaction efficiency Even the biogas power generation is transformed into biomass fuel cells or the biomass produced is transformed into edible algae.


    With these thoughts in mind, Chen Xin sincerely congratulated himself for picking up the system when he entered the refuge, instead of turning a blind eye to it as an ordinary meteorite.


    Now that he has decided to build an oxygen generator, Chen Xin obviously needs to take stock of his own resources first.


    After all, it''s not like upgrading an existing item. It can be upgraded directly with the help of the system''s survival points.


    This is also the biggest deficiency of this system. It can''t create something out of thin air, and can only upgrade according to what it has.


    Even if the items used as the basis for upgrading are simple and primitive, as long as there is a material basis, the system can continuously improve them.


    But without this foundation, nothing can be said.


    So even if Chen Xin builds a water tank with a wooden board to let algae grow in the water, and then insists that it is an oxygen generator, he has to build the water tank first.


    Fortunately, Mr. Chen is not short of materials. He doesn''t need to build a sink with wooden boards.


    To build an algae circulating oxygen generator, the first thing to have is not the water tank, but the foundation for algae growth, that is, the biological facade.


    This is not complicated. If you are not so particular about it, the screen windows used at home can also be used.


    Let the algae attach to it, and then provide water, carbon dioxide and light. Soon the algae will begin to grow and reproduce, and photosynthesis will release oxygen.


    As for the sink, it''s not necessary, because you can get a water pipe to hang on the attachment of the algae, and keep the algae moist through the water pipe, instead of soaking them in the water completely.


    If the conditions are better, it can provide a better basis for algae attachment.


    The German technology is to make hollow glass plates, connect the supply line and discharge line on these hollow glass plates, and then inject culture medium into the hollow glass plates to cultivate algae.


    At the bottom of a single insulating glass plate, carbon dioxide as a nutrient is injected into the medium through the supply pipeline to produce bubbles. The vortex formed during the rising of bubbles will stimulate the algae in the medium to absorb carbon dioxide and light, carry out photosynthesis, and continuously grow and reproduce.When the algae grow and propagate to a certain extent, the algae in the insulating glass plate will be recycled to harvest biomass.


    According to the experimental data given by the German at that time, such a one square meter insulating glass panel can produce 900 kg of biomass a year, about 10 liters of methane per day, and a 200 square meter insulating glass panel can produce more than 600 cubic meters of methane per year.


    The methane used for power generation can generate 4500kwh of electricity and 6000kwh of heat energy, which can be said to be quite clean and efficient.


    Of course, the Germans use fuel cells, rather than simply burning methane to generate electricity, which is much more efficient.


    As far as Chen Xin''s current supplies are concerned, he can only use screens or other things that are easy to attach to make an attachment foundation, and then drench it with water and provide light to let it grow algae.


    In short, it is to build a simple device, let it run first, and then consider upgrading it to improve operation efficiency and expand production capacity.


    All it takes to make a simple device is a water tank, a micro vacuum pump, several PVC pipes and an attached facade.


    After looking through his storeroom, Chen Xin quickly found out what he wanted to use, although they may not be so suitable and need to be reformed.


    There are many different sizes, so the pipes and vacuum pumps can''t be connected. The sink is just a plastic box, and the attached facade is also a screen window removed from the window of the container house


    Looking at these things, Chen Xin thinks that he should make a workbench for himself first.

 Chapter 76

    "What are these?" In the central room of the air circulation pipe in the shelter of the police station, uncle Ding looked at the things on the shelves in front of him and asked, "looks like a glass plate?"


    A technician who was debugging the equipment heard uncle Ding''s question. While continuing his work, he explained to him: "this is an algae culture tank. The standard name is biological reaction facade..."


    After checking the condition of a biological reaction facade, the technician continued: "of course, from the material point of view, you can really call them glass plates. These are all made of plexiglass. The facade is hollow. After filling the culture medium, water and carbon dioxide will be used to propagate algae."


    Looking at thousands of pieces in front of us, and still installing more biological reaction facades, the manager of the city police station with Uncle Ding asked, "can they be used to supply oxygen? By the algae? "


    "Yes, by the algae." The technician nodded and tapped a biological reaction facade on one side with his finger: "these algae will get the light energy required for photosynthesis under the sunlight. We fill carbon dioxide into it through the pipe at the lower end of the facade to make the algae inside carry out photosynthesis, while the pipe at the top is responsible for collecting the oxygen released by these algae to supply the oxygen The air circulation system of the shelter is used. "


    "That''s all What''s the facade of biology? " Another manager also spoke, revealing a strong suspicion and Distrust: "can these things be used by 20000 people in this refuge?"


    When the manager spoke, the managers of the city police station all had the same look on their faces.


    It''s not that these managers don''t know how to pretend to understand or despise the technicians, but the thousands of glass plates installed here can supply the oxygen consumption of the whole refuge, which really makes people doubt whether it can really do it.


    "These biological facades use microalgae biological reaction oxygen production technology. In the past, the German people had done a similar technology experiment, and built a building house with this biological reaction inside to build an external wall. The biomass produced by such a biological house after reaction can provide enough heat and electricity to meet the needs of the surrounding three houses." The technicians were not surprised by this, and continued to explain to the managers of these municipal police stations.


    After all, it''s about the life and death of more than 20000 people in this shelter, and the technicians feel that they really should explain it more clearly.


    "We have improved this technology. Originally, we intended to take it to the submarine for experiment, to see if it can be used as the oxygen supply system of the submarine, so as to improve the stay time of the submarine underwater." The technicians did not hide the fact that this was originally a military experimental technology, but continued: "the efficiency of algae in producing oxygen is actually the highest among all the organisms on the earth. 70% of the oxygen on the earth comes from the marine ecosystem, so it is absolutely no problem to rely on algae to supply oxygen for the refuge in theory.


    As for whether oxygen generation can guarantee the survival needs of 20000 people, please don''t worry. The system is designed to meet the needs of 30000 people.


    Moreover, although the oxygen content in the outside air will decrease, it is not to say that it will decrease to the point where human beings can not survive, but the oxygen content will decrease to a degree similar to that in plateau areas. The main purpose of this system is to prevent carbon dioxide deposition and oxygen deficiency caused by underground structure in the shelter after the oxygen content decreases. "


    The technical staff''s explanation reassured these managers. After listening to the explanation, several people in charge of logistics discussed something.


    "Do you say that the oxygen content of the external environment will not drop to the point where human beings cannot survive?" When the technicians mentioned the problem of oxygen content in the outside world, uncle Ding was particularly concerned about it, because the special police force is currently the most out of the field department in the police station, and he was very concerned about it.


    The technician seems to be very interested in solving this problem. He stops his work and explains: "the total amount of oxygen in the earth''s atmosphere is about 10 billion tons, and the oxygen a person breathes is about 270 kg per year.


    Even if calculated by 0.3 tons, even if the earth''s 7 billion people are still alive, it will take 550000 years to consume all the oxygen in the atmosphere, and it will take thousands of years to reduce the oxygen content by 1%. "


    Speaking of this, the technician laughed and jokingly added: "of course, in fact, it is impossible. Even if the atmospheric environment drops by only one or two percentage points, it is enough to cause human hypoxia reaction. If the oxygen content in the atmosphere is less than 15%, it is enough to cause serious consequences.


    The previous meteorite impact and global fire have consumed a considerable part of the oxygen in the atmosphere. According to the calculation, the oxygen content in the atmosphere has decreased by about 0.5 to 1 percentage point.


    In addition, there is no sunlight, photosynthesis is nearly stagnant, and there is no new oxygen in the atmosphere. The oxygen content in the external environment can still be maintained at about 18-15%. Of course, it depends on the region and environment.


    However, due to the problems of underground buildings and the ventilation system, the oxygen content in the shelter will be lower than that of the outside world. According to the calculation, if there is no oxygen supply inside the shelter, the oxygen content is likely to fall below 15% and form carbon dioxide deposition, leading to hypoxia. "Hearing the explanation of the technician, uncle Ding nodded clearly, but his brow wrinkled.


    Whether the external environment can survive or not, the special police forces need to consider different issues when they go out of the field.


    If the external environment cannot survive, the danger of the external environment will mainly come from the bad natural environment, which can be ensured by improving the field personnel''s protective equipment and security measures.


    However, if the external environment can still survive, but the conditions are worse, there is no doubt that the risk will be greatly increased for the field personnel who go out to perform the task.


    In peacetime, there are still many kinds of crimes, such as robbery, robbery and theft. In the end, with the weakening of government control over the city, even within the shelters, there will be crimes. What''s more, the wild areas are now beyond the reach of the government?


    The technician seemed to see Uncle Ding''s worry, and said with a smile, "but you don''t have to worry too much, comrade. In addition to the lack of oxygen, the temperature in the wild will seriously restrict human activities in the wild. With the low temperature of dozens of degrees below zero and the lack of oxygen, not many people can stay in the wild for a long time in this harsh environment."

 Chapter 77

    After listening to the technician''s words, uncle Ding thought that it was the same thing. Today''s external environment is not the peaceful era before the disaster. If you hide in the mountains, you can hide for a month without a net like investigation. The extremely cold and anoxic natural environment is enough to kill anyone.


    It''s like climbing Mount Everest or going to the north and south poles before a disaster. Without adequate preparation, professional protective equipment and warm clothing, you will only have cold and death.


    However, while watching the technicians install these biological reaction facades, uncle Ding suddenly thinks of his daughter Ding Ning and Mo Qingyan.


    Although Ding Ning and Mo Qingyan haven''t visited the shelter where they are, Qin LAN knows something about it when she went there, and has reported it to him when she came back, so uncle Ding knows that they don''t have greenhouses or any oxygen generating equipment.


    Out of worry about his daughter, uncle Ding asked the technician, "is it troublesome to make anesthesia with this kind of equipment? If private shelters want to build a similar device, can they do it? "


    The technician took a surprised look at Uncle Ding. It seemed that the special police captain''s focus was a little strange, but he explained: "if we just make a similar simple device, it''s not troublesome. It''s just that the oxygen generation efficiency and maintenance and cleaning of the equipment will be very troublesome.


    In the case of private shelters, if you want to make oxygen, it is better to plant greenhouses. In the case of electricity and water, greenhouses can provide both food and oxygen, which is much simpler than making a set of such oxygen making equipment. "


    Technical personnel''s words let Dingshu heart sink, immediately to dingning they are full of worry.


    He wanted to ask the technicians if they had any more equipment, but this was swallowed by Uncle Ding.


    The equipment in front of him is for the survival of more than 20000 people in the shelter. Uncle Ding can''t embezzle it for his own sake, even if he only needs a small part of it.


    Moreover, compared with getting a set of equipment for Ding Ning and Mo Qingyan, the easier way is to let them move to the shelter.


    This can not only solve their survival problems, but also provide security for their safety.


    After all, no matter what, in the shelter of the police station, uncle Ding, as the captain of the special police, is in charge of more or less, which can guarantee Ding Ning''s safety.


    After figuring out this truth, uncle Ding didn''t ask the technicians any more. He made up his mind to send someone to pick her up no matter what mood Ding Ning was in this time.


    It''s a big deal. I bow my head and admit my mistake to her.


    It''s no shame to bow to your daughter and apologize.


    However, Chen Xin had to do it by himself.


    However, instead of building another workbench, Chen Xin borrowed the workbench attached to the weapon cabinet.


    Although it''s a workbench for making and maintaining weapons, it should have all kinds of tools, and the related auxiliary materials such as adhesive tape and glue are also quite complete. Even if the tools are not very handy, it''s not particularly difficult for Chen Xin to transform the existing materials and make a simple oxygen making box.


    A hole is made on the side of the plastic box to connect the pipe and the micro vacuum pump, and then a vertical pipe is connected, which is mounted on the screen window placed in the plastic box to ensure that the water from the pipe can flow to the screen window, and then a fill light is installed in front of the screen window. This simple algae oxygen making box is completed.


    Although it is rough and terrible, the pipes are all connected by adhesive tape and sealed by glue, and the pipes and screens lack support, it seems to be tottering, but in the judgment of the system, it is still a complete survival equipment.


    "Simple algae biological oxygen box"


    "upgrade scheme 1: increase algae attachment surface, improve algae breeding efficiency, oxygen production + 10%, biomass production + 5%, upgrade the required survival point of 100"


    "upgrade scheme 2: change the water tank structure, improve algae photosynthesis efficiency, oxygen production + 15%, upgrade the required survival point of 80"


    see system improvement After providing an upgrade plan, Chen Xin was relieved. Since this crude device can be identified as an algal biological oxygen box by the system, his next task is to collect materials or directly use survival to upgrade the oxygen box.


    From the two upgrade methods provided by the system, Chen Xin also judged that the two upgrade routes of the algal oxygen tank should be the fuel cell route to become a biological generator, and the other to become a pure oxygen generator.


    The first kind of multicellular algae is obviously more suitable for attachment growth, which can recover a large amount of biomass for fuel cell to convert electricity.


    The second is more suitable for planktonic life. The purpose is to obtain more oxygen, not to recover biomass.


    For the two upgrading schemes, although both can be chosen, Chen Xin obviously prefers the first scheme, because he needs to obtain biomass fuel cells to provide power for the refuge.


    After all, he also has a greenhouse to provide oxygen. He doesn''t need to rely on the oxygen tank to produce a lot of oxygen, which is only auxiliary equipment in his plan.It''s just that the upgrade of this oxygen box can''t be carried out for a while. On the one hand, there are not enough materials for Chen''s novice. On the other hand, he has used up his survival points by upgrading his weapon cabinet and protective clothing.


    Considering that the oxygen content in the atmosphere is not so high that people can''t breathe, he also has a greenhouse to provide oxygen, and Chen Xin is not very urgent to upgrade the oxygen box.


    Moreover, Chen Xin, who reviewed the data at this time, also reflected that even if the earth''s surface and marine ecology all collapsed and there was no sunlight for photosynthesis, the oxygen in the earth''s atmosphere would be enough for humans to breathe for a long time.


    Although the previous global fires and meteorite impacts consumed a lot of oxygen in the atmosphere, the remaining oxygen is still enough for human beings to use for a long time, even enough to support the dust in the sky to disperse and the ecological reconstruction of the earth.


    Moreover, according to Chen Xin''s conjecture and the data he found in the data in his computer, the current situation of complete darkness and no light will be improved for at most one year.


    Although the dust in the sky still blocks most of the sunlight, the earth''s surface may change from a dull environment to a low light environment within one to three years. In the ocean, which accounts for 70% of the earth''s surface, algae can produce oxygen through photosynthesis in a low light environment.


    In other words, human beings may face the problem of lack of oxygen, but they will not be unable to survive because of lack of oxygen.


    The existence of oxygen generator is only to improve the living environment of human beings in the refuge and make human beings live better.

 Chapter 78

    On the road leading to the suburbs, a truck was moving. On the truck were the small agricultural machinery left in the materials that the special police agreed to exchange with Chen Yu, as well as the material samples that they planned to use to exchange vegetables with Chen Yu.


    The previous transaction with Chen Yu for vegetables is of course not worth mentioning to the whole police station, even if Chen Yu can provide nearly 2000 Jin of fresh vegetables a month after upgrading the greenhouse.


    But Chen Yu''s deal is only with the special police team, with 1000 or 2000 catties of vegetables a month, which is very attractive to the special police team.


    What''s more, the key point is that although the output of 2000 Jin vegetables is very attractive, it''s not too attractive. It will make the people of the special police force use their brains.


    After all, the people in the SWAT team say more, and less is not less.


    It''s just that there are more than 100 regular SWAT members, and 200 Jin of cabbage is only enough for the master to fry once. If you fry twice, you have to mix the mouse meat with the weight.


    Although people with a darker mind may be moved to occupy Chen Xin''s little refuge and enjoy themselves, for the special police force, if it''s only one or two thousand kilograms of vegetables a month, it''s not worth it.


    In any case, today the government is sound, the country and the army are still intact, and the city government also relies on the special police team to maintain the order of the city. However, the special police team is only a part of the police station, and the special police team has not been able to do whatever they want.


    "Sister LAN, do you think ah Xin will accept the exchange terms offered by my father?" Ding Ning, who has put on his police uniform again, sits in the co driver''s seat and asks Qin LAN who is driving.


    Under the tough attitude of Uncle Ding, Ding Ning is taken back to the shelter of the police station by him and put on her police uniform again. However, she is also transferred from the original unit to the special police team, responsible for fighting Qin LAN. In name, she is a reserve observer.


    This time, we are together with Qin LAN to send materials to Chen Xin and pull back the vegetables exchanged this month.


    Qin LAN, who is driving attentively, hears Ding Ning''s question and thinks about it for a while. He says, "based on my understanding of ah Xin, he should accept the price of living materials for vegetables. As for other materials, it''s up to us to talk with him."


    This is also Qin Lan''s main task this time, and Chen Xin to negotiate the specific proportion of material exchange vegetables.


    At present, the special police team is still rich in materials. In addition, they can get abundant supplies from the city government every month. In this situation, they can exchange a small part of fresh vegetables with Chen Xin to improve their food.


    Although it''s true that this is the end of the world, with the guarantee of material supply, ten or two kilos of vegetables for the special police force are really just improving the food. After all, vegetables are not staple food and can''t be used as food.


    Hearing Qin Lan''s reply, Ding Ning couldn''t deny it. He pulled out his gun from his waist belt and put it on his hand to play with. In a dissatisfied tone, he muttered: "ah Xin is still too unguarded. Even if it''s my relationship, he shouldn''t trust my father so much. If someone wants to rob his shelter, a gun will take care of him. "


    For Ding Ning''s words, Qin LAN naturally agrees. In her opinion, Chen Xin''s refuge does not have enough security measures.


    Although the two gates are enough to deal with natural disasters, it''s hard to say how important the two gates in the refuge can play if someone really has a wrong idea.


    The two arrived at Chen Xin''s shelter in a truck and still opened the door with a short wave radio.


    "Xiaoding? You''re back at the police station? Have you made up with Uncle Ding? " Chen Xin looked at Ding Ning''s police training clothes and a full set of single police equipment, and couldn''t help asking her.


    "Dad sent sister LAN to arrest me. What else can I say? At least I can put on my uniform again. " Ding Ning explained to Chen Xin, but at the same time, he explained helplessly: "originally, my father agreed to let sister Yan and xinxiaomei move to the shelter of the City Council, but sister Yan didn''t want to. Now she still lives in her own home."


    At the same time, Ding Ning''s face also showed his worry about Mo''s sisters.


    Before Chen Xin and Mo Qingyan talked about oxygen, Ding Ning naturally knew about it, and her father took her back from Mo Qingyan''s shelter to the shelter of the city police station. If Ding Ning could not think of the reason, she would be a little silly.


    From Ding Ning''s words, Chen Xin naturally recognized her worry, and he could not help frowning.


    But Mo Qingyan''s choice is not easy for him to interfere. He can only shake his head and say, "I''ll talk to long Niang later. I can''t help her make an oxygen generator."


    "Ah Xin, can you still make an oxygen generator?" Ding Ning and Qin LAN are obviously surprised by what Chen Xin said.


    Looking at their amazing appearance, Chen Xin couldn''t help feeling a little strange, so he said: "it''s easy to make a simple oxygen generator. You can transform one by yourself with aquarium or green plant box, even if you don''t change it. You can directly replace it with green plant box, but the oxygen supply is very low."


    "Oh, so it is!" Ding Ning nodded her head in a hurry and expressed her understanding. Just now, she thought Chen Xin was talking about an oxygen generator like the oxygen generating equipment used in the official refuge. She didn''t think about this simple oxygen generator at all.Chen Xin didn''t care about Ding Ning''s attitude. He asked Qin LAN, "a LAN, did you bring what I asked for last time?"


    "Don''t worry, all the small farm machinery you asked for last time was in the car, and this time I brought you something else." Qin LAN sure said, came to the back of the truck opened the car.


    Sit down and I''ll pour you some water Qin LAN will bring things into the storage room, Chen Xin asked the two to sit down in the living room, while looking for a cup to pour water for the two.


    It''s just that Chen Xin is the only one living in the shelter. He doesn''t prepare any extra water cups. After looking for them for a long time, he can''t find a cup to pour water for Qin LAN and Ding Ning.


    Seeing this scene, Qin LAN rushed to Chen Xin and said, "don''t look for ah Xin. There''s water in the car. You don''t have to bother. Sit down first. I have something else to tell you


    Hearing what Qin Lan said, Chen Xin had to give up trying to find a water cup and sat down on the sofa, waiting for Qin LAN to say something.


    He took out a piece of paper from his body and handed it to Chen Xin. Then Qin Lan said, "you said before about the exchange of materials for vegetables with our special police team. After discussion, the team leader and political commissar have agreed. This is the material quotation we sorted out. Ah Xin, please see if you can accept it. If there is something that needs to be revised or is not suitable, we will discuss it again. "

 Chapter 79

    After Qin Lan''s offer, Chen Xin nodded and looked at it carefully.


    It says all kinds of materials that the Swat can provide, including common building materials such as steel and cement, as well as living materials such as food, salt, sugar and toiletries. As for fuels such as gasoline and diesel, this paper also lists them.


    However, the most eye-catching items on this list are the qsz92g semi-automatic pistol specially marked in red and the matching 9mm bullet.


    "Even the gun can be changed! Is there no problem with this kind of thing? " Chen Xin of course noticed this specially marked red place, surprised to see Qin LAN.


    Qin LAN nodded and explained to Chen Xin, "ah Xin, you live alone in such a place in the suburbs. Now it''s safer to have a gun in this world, so I asked the team leader for help and got a gun for you."


    "Ah Xin, there are only two iron gates here. If you are cheated to open the gate, there is no room for resistance." One side of Ding Ning also couldn''t help but make complaints about the safety of Chen Xin''s refuge.


    Chen Xin naturally knows that the safety of his refuge is indeed worrying. Although the two protective doors have no problem in dealing with disasters, they can''t resist those who want to.


    So he is also planning to transform the gate of the shelter to increase the safety and protection of the shelter.


    However, Chen Xin has no urgent need for pistols. After he can make pistols, he doesn''t need to change guns with the SWAT team.


    But after less than a second of thinking, Chen Xin decided to exchange the gun.


    This is not to say that the guns provided by the special police force are better than Chen Xin''s own, but that it is an illegal act to manufacture guns in Yanguo.


    Although this means before the end of the world, Chen Xin, as the country with the strictest gun control in the world, does not think that the country will allow private ownership of guns after the end of the world.


    It''s better to be able to change a gun from the SWAT team and give yourself a reasonable reason to use it than to build one and then use it secretly.


    And this is Qin Lan''s heart.


    "Thank you, but what about the bullet?" Chen Xin looks at Qin LAN and asks her.


    "You can also change the bullets, but the quantity can''t be too much at a time. It can give you 50 bullets at most." Qin LAN explained to Chen Xin, as if afraid that he would think more: "it''s not that he won''t give you more bullets, it''s just for the sake of safety."


    Chen Xin heard Qin LAN say so, also nodded to show understanding: "don''t worry, I can understand, in the end Yan state is forbidden gun."


    See Chen Xin no opinion, Qin LAN this just feel relieved, let Ding Ning will bring a black box to Chen Xin.


    Seeing the letters qsz92g printed on the box, Chen Xin knew that it was the gun Qin LAN provided him.


    He reached out and opened the box. It was a black pistol inside.


    In addition to the gun, there are two magazines and a box of orange bullets in the box.


    Chen Xin picked up a magazine and saw that there was no bullet in it, so he picked up the gun in the box, inserted the empty magazine directly into it, then pulled the sleeve, held the pistol in both hands and made a standard holding posture.


    Qsz92g semi-automatic pistol is the latest generation of Police Pistol in Yanguo. It is an improved version of military qsz92 pistol.


    The biggest difference between the police type and the military type is the caliber. The military type is 5.8 mm in diameter, and the magazine capacity is 20 rounds. The police type is 9 mm in diameter, and there are 10 rounds and 15 rounds. The one Qin LAN brought to Chen Xin is the police type, and both magazines have the capacity of 15 rounds.


    In terms of the danger Chen Xin may face, two magazines with 30 rounds of ammunition are more than enough.


    "Ah Xin, have you ever used a gun before?" Qin LAN looks at Chen Xin''s skillful gun holding posture and frowns. As Chen Xin''s ex girlfriend, she has no idea that Chen Xin can even use a gun.


    Hearing Qin Lan''s words, Chen Xin couldn''t help laughing: "ah LAN, you look down on boys, don''t you? Which boy didn''t play with a gun when he was a child? Although the toy gun is not a real gun, the posture of holding the gun can be imitated as follows. "


    Chen Xin certainly won''t tell Qin Lan that he is actually playing with the pistol made by himself these days. He has tried all kinds of gun holding postures on TV.


    Although it doesn''t have much practical value, the feeling of holding a gun is still tempered.


    Qin LAN is suspicious of Chen Xin''s explanation, but since she has given the gun to Chen Xin, it''s better for him to use the gun, so she doesn''t say anything more. Instead, she asks Ding Ning to put another box in front of Chen Xin.


    This is a paper box. It''s much bigger than the box with pistols just now. It''s a little heavy because it''s full of things.


    Chen Xin uses a knife to cut open the box. The top half of the box is a variety of daily necessities, and the bottom half is a layer of plastic boxes.


    "This is the daily necessities that everyone in the shelter can get in a month, including toothbrush, toothpaste, towel and soap, as well as one month''s rations." Qin LAN sees Chen Xin looking at the things in the box, so she introduces and explains them to him.The toothbrush, toothpaste and soap in the box are put in a plastic bag, some of which are similar to the washing bags Chen Xin had seen in some express hotels before.


    In addition to these things, there is a roll of toilet paper in the box.


    Chen Xin took these things out and put them on the table. All that was left in the box was a layer of plastic boxes.


    Qin LAN took out a box from the box, opened it and showed it to Chen Xin: "this is the main food eaten in the shelter at present. It contains two portions of rice cooked with rice, potatoes and meat, and two energy bars.


    Each shelter will deliver raw materials and boxes used up last month to the processing plant every month, and the processing plant will process the finished products and return them to each shelter, so they are basically fresh. "


    Looking at the two bricks of food Qin LAN took out of the box and the two energy bars that looked like compressed biscuits mixed with nuts, Chen Xin couldn''t help touching his eyebrows: "it seems that the food is OK."


    "It looks ok. The meat inside is mouse meat." Carnivorous Ding Ning could not help but Tucao, who could make complaints about lunch meat and canned pork in Mo Qingyan''s refuge, and returned to the police shelter.


    Chen Xin didn''t mind this, but nodded normally: "rat meat actually tastes good. Now in this world, it''s unrealistic to raise pigs and cattle."


    Chen Xin is very satisfied with Qin Lan''s box of so-called shelter''s standard living materials. The food and use are pretty good. Although it''s not very good, it''s certainly enough.

 Chapter 80

    Qin LAN took a list of many goods and materials, but these goods and materials need Chen Xin to exchange with vegetables produced by his refuge. The list also lists the appropriate exchange ratio after discussion by the special police team.


    Of course, Chen Xin has no objection to material exchange, which is also very good for him, but he has different opinions on the proportion of material exchange.


    "Five bags of cement in exchange for one hundred catties of fresh vegetables? This ratio is acceptable. " Chen Xin looked at the exchange ratio marked on the list and checked one by one: "but is the steel bar a bit exaggerated? How can you change a steel bar with 20 jin vegetables


    Reinforcement is very useful for Chen Xin. Besides, reinforced concrete is necessary to reinforce the gate of the shelter.


    "What we provide is the standard steel bar of ¦Õ 12x12, and ah Xin, as you know, there is no steel factory in this city, all of which depend on Railway input. It''s understandable that the price is a little more expensive." Qin LAN explains to Chen Xin.


    Although they used to be girlfriends and girlfriends, they obviously didn''t worry about their past feelings when they were bargaining. They were both haggling.


    "But only 20 jin vegetables can be replaced with a steel bar. The price is still out of line. I think 10 jin is an acceptable price." Chen Xin opens his mouth and cuts the proportion of exchange in half, but his eyes look at Qin LAN, waiting for her to bargain.


    Sure enough, Qin LAN shook his head and refused directly: "ten jin is too little, 18 Jin at most."


    However, Chen Xin did not give up, still repeated: "ten jin, or I''ll go to someone else for it."


    "It''s impossible, even if you put it before the disaster, you can''t exchange ten jin cabbage for a steel bar." Qin LAN shook his head, but still made a compromise: "15 Jin, no less."


    Hearing what Qin Lan said, Chen Xin laughed and said to her, "one step back, 12 Jin. First get me 50 steel bars. I need them urgently."


    "In urgent need? Xin, what are you doing? Need so much steel? " As soon as Qin LAN heard that Chen Xin was in urgent need, she was curious.


    Chen Xin said directly: "it''s been three months since the end of the world. The temperature is almost freezing. I''m going to reinforce the gate of the shelter before it freezes. So in addition to steel bars, we also need cement, sand and steel plates. I can accept the exchange ratio of these building materials. Let''s ship them together as soon as possible. "


    Hear Chen Xin said is to be used to strengthen the shelter gate, Qin LAN clearly nodded, very happy agreed to come down.


    Now the official shelters are also undergoing large-scale expansion work. All the shelters are allocated a large amount of construction materials. Chen Xinyao''s supplies are not large. The special police team only needs to get a little out of their own supplies to meet his needs.


    After negotiating the demand for building materials, Chen Xin put forward another demand that was not on the list: "Alan, can you help me get some glass? It''s better to have a big glass tube like a cylinder. It''s better to have an aquarium of this shape. Besides, there''s a vacuum pump. "


    "Yes, I can, but what do you want with these things, Xin?" Qin LAN asked strangely.


    Chen Xin explained with a smile: "the aquarium can be transformed into the proposed algae oxygen generator. Living in an underground shelter will definitely have oxygen problems. I need one myself, and longniang also needs one. I can make one for her to exchange all her good wine. Drinking in cold weather can keep her warm."


    "You''re not a hairy boy. What are you doing drinking to keep warm?" Although Lan Qin make complaints about this, he still promised Chen Xin''s request, and wrote down what Chen Xin wanted in his little notebook.


    They checked the exchange ratio of all kinds of materials on the list again, as well as several items of materials added by Chen Xin, which ended the bargaining between them.


    At the end of the bargain, the topic between the three became much easier. Chen Xin also asked about some topics he was interested in.


    "What''s the main food in the shelter now? Isn''t it really mouse, earthworm and mushroom soup? " Chen Xin made a joke.


    But mice, earthworms and mushrooms are indeed suitable for raising animals and plants in low temperature and dark underground environment, and they are also the main food sources of shelters announced by the state before the disaster.


    For this problem, Ding Ning just shrugged and leaned on the sofa in Chen Xin''s living room: "I just avoided the difficulty recently. I''m not very clear about it, but what I eat is basically mouse meat stewed with potatoes and mushrooms, but it''s strange that rice can still be full."


    "the state has gathered a lot of rice before the disaster, and now it is not surprising that steamed rice is eaten." Qin LAN knows more about the situation than Ding Ning, so she explained to Chen Xin: "as for mushrooms and potatoes, mushrooms are the things that are planted in every refuge at present. The yield of mushroom sachets provided by the state is good. Now they can be harvested once a month. If the planting area is not enough, in fact, mushrooms alone can meet the needs of food."


    At this point, Qin LAN stopped for a moment and then continued: "as for potatoes, the country has not popularized them in a large area. Although they are high-yield, the demand for soil and fertilizer is also high, which is not as stable as that of mushrooms.Moreover, water and electricity are consumed, and the general shelters do not have the conditions for large-scale planting, so the city has opened up a special underground planting area near the power plant to grow potatoes, and the yield is not too high. "


    Chen Xin heard Qin LAN say so, also understand of nod.


    In fact, when he built the shelter, he first thought of planting potatoes.


    Thanks to the movie Mars rescue, everyone knows that potatoes can survive, so they feel that in the end, shouldn''t potatoes be planted at this time?


    Especially in all kinds of travel novels, in addition to burning glass to make soap, looking for potatoes is almost a must.


    It seems that everyone thinks that this is a miracle. For traditional agriculture, the yield per mu of several thousand jin of crops may not be as high as one tenth of that of potatoes, which is undoubtedly a blow to dimension reduction.


    Potatoes do have many advantages. First of all, the yield is high. It seems that the yield of several thousand jin per mu is very common for potatoes.


    Secondly, potatoes are very suitable for growing in alpine regions. Mongolia and Siberia are the main producing areas of potatoes. It can still grow healthily in the environment of temperature below 10 degrees, and it does not need too much water irrigation to ensure high yield.


    And potatoes are also rich in nutrition, rich in starch, in cold environment can provide a lot of heat and nutrition for the human body, is indeed an important food to maintain life.


    But potatoes are not perfect.

 Chapter 81

    First of all, the requirements of potato planting on soil are very strict. Only the soil with deep soil layer, loose structure, good drainage and ventilation and rich organic matter is the most suitable environment for potato growth.


    And this is not over, the growth and development of potatoes need more than ten kinds of nutrients, the demand for fertilizer is quite large.


    If potatoes are continuously planted in a plot, the soil fertility will be greatly reduced due to the absorption of soil fertility by potatoes. In the second year of continuous cropping, the yield will be reduced, and the tuber quality will also be reduced, especially the diseases, insects and weeds will be more serious.


    Even the protagonist of Mars rescue, when planting potatoes on Mars, is the vacuum dried excrement saved by the astronauts before reuse, fermentation into manure, before planting potatoes.


    More importantly, the stems and leaves of potato plants are poisonous, even the potato itself is poisonous.


    Solanine and Chaetomium are the main components of potatoes. Generally, when heated to 170 ¡æ, the toxin will decompose.


    Although the toxicity of cultivated potatoes is not high, but the consumption of more than 1.4 kg, the cumulative toxicity in the body will still produce toxic reactions.


    As for the solanine produced after potato germination, it is a kind of toxin that will be seriously poisoned if 0.2-0.4g is ingested.


    Especially for pregnant women, if long-term consumption of potatoes, which contains alkaloids accumulated in the body is likely to lead to fetal malformation.


    Before the disaster, of course, you can eat and grow potatoes at will. After all, there are a lot of potatoes, and you can avoid many problems in planting as long as you pay attention to rotation and fertilization.


    However, the toxin in potatoes is an unavoidable problem. After all, unlike before the disaster, people can choose a variety of food and eat many different kinds of food. The abundant supply of materials can also make people always eat fresh potatoes, greatly reducing the risk of poisoning.


    But in the end, there was no such condition. The underground land resources were limited. Basically, there would only be one kind of staple food.


    And that will lead to long-term consumption of potatoes.


    In addition, the shelter certainly can not be planted and eaten now, and the mildew and germination of harvested potatoes during storage can be predicted.


    Before the disaster, it must be throwing away. No one will eat the sprouted potatoes.


    But in the last days, this is an important food reserve. Mice, cockroaches and earthworms are used to eat. How many bad potatoes? As long as you can''t eat dead people, you can eat them cooked!


    So at this time, the toxin in potatoes is a problem that cannot be ignored.


    Considering from the national level, if you need to choose a staple food of doomsday at this time, potatoes are obviously not the best choice, especially when planting potatoes requires a lot of light.


    Because of these factors, Chen Xin chose upland rice as the main food source of his refuge.


    After seeing off Qin LAN and Ding Ning, Chen Xin tidies up the place and sits at the desk.


    While taking out the pistol from Qin LAN and pressing the bullet into the magazine on the workbench, he is also thinking about making an oxygen generator for Mo Qingyan.


    Although he chose a very simple and crude way to make his own oxygen generator, and later relied on the system upgrade to get the oxygen generator, this method is still too extensive.


    What''s more, the simple oxygen generator he made before is not worth mentioning in terms of efficiency, and the utilization efficiency of light energy is still very low.


    However, after upgrading the system, even Chen Xin''s simple and crude oxygen generator is now decent.


    Chen Xin chose the second plan to upgrade. The original square plastic box was changed into a straight tube. The fill light was directly installed in the hollow part of the tube to irradiate from the inside to achieve the maximum efficiency of light utilization.


    The algae are directly raised in the tube for reproduction, the oxygen will be discharged from the top, and there are pores at the bottom to inject carbon dioxide.


    The settled algae bodies will be filtered during the water cycle to recover biomass, which will be used to generate methane for fuel cell power generation.


    After upgrading, the whole system has become a green cylinder with a height of two meters. The light comes out faintly, and the whole cylinder is full of algae.


    The oxygen produced by such a device can maintain the survival needs of a normal person, while the electric energy produced by such a device can maintain the energy consumption of the whole equipment except for the light supplement lamp, with a slight balance.


    After all, under normal circumstances, the algae oxygen generation technology relies on the sunlight to promote the photosynthesis of algae. Now there is no sunlight, so the energy consumption of the fill lamp must be supplemented by other energy.


    Mo Qingyan''s refuge has all the power and water supply in the city. Although the supply is limited, it is not a problem to maintain the operation of the equipment.


    The bullets were pressed into two magazines, and Chen Xin put one of them back into the pistol.Holding the gun for a while, he could not help taking out the pistol he made and comparing the two guns on the workbench.


    Compared with the pistol made by Chen Xin himself, the caliber of the pistol Qin LAN gave him is obviously larger, but the weight is lighter. This is because Yan Guo used engineering plastic as the handle when manufacturing qsz92g semi-automatic pistol, which reduced a lot of weight.


    As for other performance differences, Chen Xin can''t compare the quality of the two guns without actually taking out dozens of bullets. That requires his professional knowledge and experience in using guns.


    After a little consideration, Chen Xin decided to use the pistol he got from Qin LAN as his usual self-defense weapon, while the pistol he made himself was put in the bedside table of his bedroom as a spare.


    This is also a kind of security strategy. It''s a good way to improve your ability to deal with danger to prepare weapons and equipment in the nearest place.


    Although in Chen Xin''s view, as long as the gate is closed and there is no heavy firepower in his refuge, it is very difficult for him to cause any security problems that he needs to deal with with with a gun.


    However, it is very important to have a gun in hand in case of any problems.


    After that, Chen Xin took his bow out of the weapon cabinet.


    Archery was just a hobby cultivated by Mo Qingyan before, and it had no practical use.


    At the end of the day, with the gun, the role of bow and arrow is greatly reduced. In a sense, the existence of this bow has become a chicken rib.


    What''s more, with the decrease of external temperature, the maintenance of the bow and arrow itself will become a problem if it is taken out for use.


    So Chen Xin plans to see if the bow can be used for other purposes after upgrading. If so, he plans to upgrade the bow into a crossbow, and then install it at the upgraded gate as a defense facility.


    Maybe you can''t stab with a crossbow, but it doesn''t mean you can''t use a crossbow as a mechanism.

 Chapter 82

    The steel, cement, glass and vacuum pump that Chen Xin asked for were delivered a week later.


    But this time, Ding Ning was the only one who came to deliver things. Qin LAN didn''t come here today.


    Ding Ning with a gas mask jumped out of the car and rushed to greet Chen Xin.


    Today''s weather is really bad, because there is no rain, there are too many pollutants in the air, and it is impossible to breathe outdoors without gas masks.


    "Ah Xin, here''s what you want." Wearing a gas mask, you can''t help talking in a loud voice. But if you speak louder, you can still hear clearly: "steel, cement, glass and vacuum pump you need. Aquarium is really out of reach. There is only a pile of broken glass left in the flower and bird market in the city before."


    Hearing Ding Ning say so, Chen Xin also didn''t think much of it, and nodded to her: "it''s OK. I''ll process it myself. Let''s get things in first."


    Finish saying, then and Ding Ning carry the goods and materials on the car together.


    Because they didn''t bring many things, they soon got everything into Chen Xin''s shelter.


    "It''s a tough day. I can''t imagine how to live outside without a gas mask." Closed two three defense door, Ding Ning this just took off the gas mask on the face, grew a breath.


    "Is it bad outside now?" Chen Xin looks at Ding Ning puzzledly. He doesn''t need to go out during this period of time, so he hasn''t been out all the time. He doesn''t know much about the changes of the external conditions, but he thinks the weather is very bad today.


    Ding Ning patted, afraid that his clothes had just fallen to dust, and then explained to Chen Xin: "several chemical plants around the city have exploded, especially the spherical tank area of Yanguo petrochemical. Ah Xin, your family used to belong to a chemical plant, and you know what the effect of that explosion is."


    Hearing Ding Ning say that the spherical tank of the chemical plant exploded, Chen Xin''s face turned white and nodded in silence.


    Of course, he knows about it. His parents used to work in a chemical factory, and they know a lot about it.


    In short, in a word, all spherical tanks are national special fire prevention units. Once an explosion occurs, a spherical tank is a mushroom cloud.


    "It''s a little better that it''s been raining all the time. There''s not so much dust in the air, but the rain has stopped these days, and the temperature is almost below zero, so it''s very hard to stay outside." Ding Ning sees Chen Xin nod, then continued to say.


    In fact, now the external environment can not be simply described as suffering, it is not suitable for human survival.


    If there is no professional protective equipment and gas mask, people exposed to the outside environment for half an hour will inhale too much toxic and harmful gas and dust and produce serious physiological reactions.


    In addition to the low temperature, which is now close to zero, even Ding Ning is fully armed. He not only has a gas mask on his face, but also wears a specially distributed warm winter suit.


    "Yes? Doesn''t that mean there are no survivors out there now? " Chen Xin can''t help but sigh that if the environment is as bad as Ding Ning said, even if there are survivors, they will almost die.


    However, Ding Ning shook his head and did not agree with Chen Xin: "there are still some survivors. Before Lan Jie and the special police team searched for possible survivors in the urban area, they still found a lot of people."


    "They''re lucky to survive!" Chen Xin sighed more and more about the good luck of these people.


    To survive the series of disasters after the doomsday without a solid shelter is impossible without any good luck.


    Especially when the weather gets worse and worse, they can be rescued by the special police, which is even better.


    But just now Ding Ning mentioned Qin LAN in her words. Chen Xin asked: "by the way, why didn''t ah LAN come here today? Does she have a task?"


    "Sister LAN, they went to clean up the shelters in the city today. The second batch of oxygen generation equipment distributed by the state arrived, but it was not enough for all the shelters. So the city government decided to move part of the population from small shelters to medium-sized shelters." This is not classified information, so Ding Ning did not keep it secret.


    Chen Xin immediately understood, but also worried about the question: "merger shelters, can live so many people?"


    "There''s no problem. The six medium-sized shelters in the urban area are designed to accommodate 25000 people. After the expansion, they can accommodate 30000 people. Now they are basically not full." Ding Ning shook his head and said that there was no problem. He explained to Chen Xin, "it''s better to move the people in these small refuges in. Although it''s a bit crowded for a while, it''s better than to be short of food and clothing and even lack of oxygen outside."


    Chen Xin can understand the government''s practice very well. This is the tradition of the Yan government. This country, this government and this nation have never abandoned the habit of their compatriots.


    "It seems that the country is still ready! In this way, people can be gathered together, which is not only convenient for management, but also can concentrate resources. " Chen Xin nodded and agreed with the municipal government.


    Although the inner darkness of human beings is deeper than we think, it will cause many problems if people are gathered together in this way, but it is impossible to watch these people die for fear of problems."My dad, they say the same thing. Although there are more people and more problems, it''s better than that the shelters are scattered and there''s something that can''t be dealt with in time." Ding Ning didn''t tell Chen Xin that some small shelters had something that people couldn''t bear to say.


    Those things are too challenging for human tolerance. Even if you just think about it, Ding Ning feels numb on his scalp and cold on his back.


    As for those who challenge the bottom line of human morality, a peanut is their best destination.


    These things Ding Ning knows, Qin LAN knows, even feed those people eat peanuts or Qin LAN personally do, but these things they did not tell Chen Xin.


    As for the reasons, there are so many reasons. The only thing we have to say is that they are the police, while Chen Xin is just the common people.


    Chen Xin naturally didn''t know about these things, but he could think of some things, so he said to Ding Ning: "now in this world, it''s uncertain when something bad will happen. Ah Ning, you have time to help me persuade long Niang to move in with you. Her It''s hard to save anything. "


    "I know. I''ve tried to persuade sister Yan, but she still can''t bear her own place." As Mo Qingyan''s best friend, Ding Ning could not have failed to persuade her: "but the official refuge To tell you the truth, that is to say, the security is better and the food and clothing are free. Compared with your private shelters, the living conditions are much worse. "

 Chapter 83

    Ding Ning lived in Mo Qingyan''s shelter, met Chen Xin''s shelter, and was taken back to the official shelter by his father. These days when he returned to the police station, he also saw other kinds of shelters in the city. He naturally had a clear understanding of the living conditions of these shelters after the end of the world, and also had a sharp contrast.


    When it comes to comfort, it''s naturally Mo Qingyan''s first refuge.


    Although the shelter built before the disaster was not designed to cope with the disaster, the living facilities and conditions were very complete. After years of careful management by Mo Qingyan, it was naturally comfortable to live in.


    However, when Mo Qingyan built the underground shelter, it was mainly designed for short-term refuge. Her plan was to spend about one to three years with materials.


    So her refuge is about nothing in self-sustaining ability.


    As for the abundance of materials, it is still an official refuge.


    Although it is the end of the world, all kinds of materials have become scarce and valuable, but the official shelters have national reserves before the disaster, and they also need to plan various response measures after the disaster. Coupled with the overall material allocation and planning of the country, at present, the official shelters really have everything.


    It''s just that the official shelters only consider how to make people live. As for the comfort of living and the quality of eating, they have retreated to the secondary position. They will only consider these when everyone is alive and has the spare power.


    It''s just like in the ice age, putting up a tent first gives the craftsmen a place to live, and then they will consider slowly upgrading their houses to cope with the severe cold.


    Chen Xin''s shelter is not as comfortable as Mo Qingyan''s. the shelter built with container houses embedded in the mountains is not excellent in terms of accommodation.


    However, at this end of the day, it''s very lucky to have such a place to live. Some small shelters in the urban area are not good at cold protection. Although the temperature inside is not too high to live in, they have to wear cotton padded clothes.


    And the most important thing is that Chen Xin''s shelter has a greenhouse, which can produce food.


    This is a very important point, because only self-sustaining shelters can guarantee the survival of survivors in such harsh environment that may last for decades or even hundreds of years.


    Otherwise, how long can we use the materials with more reserves without replenishment?


    "Ah Xin, what do you rely on to generate electricity here now? Gasoline? Is that enough? If it''s not enough, I''ll ask my dad to exchange more materials for you later. " Ding Ning asked Chen Xin. She thought of this question just now: "you are good at everything, but it''s a pity that energy is a problem. If the oil is burnt out, you will have a power failure."


    Thinking of this, Ding Ning also moved his mind, so he said to Chen Xin, "why don''t I go back to my father and get you a diesel generator! Diesel is more durable than gasoline, and you can use it a little longer


    "Thank you, Xiao Ding, for your kindness, but I have a plan." Chen Xin didn''t tell Ding Ning that he planned to do something about algae oxygen generation and biogas fuel cell.


    All these need to be upgraded later with the help of the system. It''s not easy to explain before upgrading, and there is no need to explain the fuzzy information state of the system after upgrading, so Chen Xin is simply too lazy to say.


    As for the diesel generator that Ding Ning said he would help him build, although the diesel generator is better than the gasoline generator in terms of efficiency and energy consumption, on the one hand, this little improvement is of little significance to Chen Xin who has the system, on the other hand, he really has no place to build a diesel oil tank.


    Now that Ding Ning has sent the materials, Chen Xin can start to work with Mo Qingyan as an algae oxygen generator.


    Compared with the one he rubbed himself before, the oxygen generator Chen Xin made for Mo Qingyan is much richer in materials.


    At least he doesn''t need to take the pipes with mismatched diameters and wrap them with adhesive tape for hard connection. In the materials Ding Ning sent, there are pipes and joints of various diameters.


    However, when he used to make his own oxygen generator, because the material was simple, and he didn''t need to do much fine work, Chen Xin just made do with the tools on the weapon workbench.


    Now that he is going to make an oxygen generator for Mo Qingyan, Chen Xin looks at the glass Ding Ning got for him and thinks that he still needs to make a workbench.


    After all, it''s OK to make do with the tools on the weapon workbench, but it''s better to use a professional workbench to process glass, connect pipes and weld circuits.


    "Fortunately, Xiao Ding has brought a lot of things this time." Standing at the door of the storeroom, looking at all kinds of things dingning sent, Chen Xin smiles.


    From the storage room to find out a few boards, nailed together as a table and countertop, and then put tools on it, a simple workbench even come out.


    When Chen Xin used to decorate his home and build a shelter, he used to see decoration workers do it.


    Three or two boards together is a table, but also the processing platform, very simple, but more convenient and practical.As long as the installation of tools and equipment, is a very good tool.


    After doing it well, Chen Xin didn''t examine and inspect it too much. He just opened the system and took a look at the upgrade materials. He spent 20 survival points to upgrade the workbench.


    After upgrading, the worktable suddenly changed its appearance. The original structure of only a few wooden boards nailed up has become a more solid table. A layer of green rubber cushion is also laid on the table, and a hanging board is added behind the table as well as the weapon worktable.


    But unlike the hanging board of the weapon worktable, the hanging board of the worktable is full of tools, while the worktable is clean, leaving a lot of space.


    Looking at the workbench in front of him, Chen Xin sat down on the stool in front of the workbench and tried the handle of the table. The smooth and flat table gave Chen Xin the impulse to do something immediately.


    However, although the workbench is satisfactory, Chen Xin works as a workbench in the garage, which undoubtedly makes the spacious space in the garage narrow and crowded.


    Chen Xin can''t help scratching his head, upgrading the garage to expand the area or simply separating the workbench as a studio. Naturally, but Chen Xin must consider the consumption of resources, especially the investment in survival.


    "It''s better to upgrade the defense of the gate now." Chen Xin sat in front of his desk, took out his notebook, looked at the information recorded on it, and muttered to himself: "maybe we can add a garage and defense room to the gate when upgrading the gate, move up the car and things for going out, and prepare to start at the gate like in the game..."

 Chapter 84

    In the bedroom, Chen Xin is leaning against the bed, using the CAD drawing software on his laptop to design the gate of the refuge.


    When the system upgrades items or shelters, it can be modified according to Chen Xin''s ideas, so Chen Xin decides to add his own ideas to the gates of the shelters.


    As the first door to resist the invasion of the outside world, it is also the strongest defense. In Chen Xin''s idea, the gate of the refuge is not only a gate.


    At the beginning, before the disaster, when the survival group discussed how to build the apocalyptic shelter, they put forward many plans for this problem.


    The original plan was put forward by the big man who made the water purifier equipment. He borrowed the federal plan of rebuilding the shelter from the abandoned missile silo, and proposed to buy an abandoned air raid shelter, and then transform it into a small shelter, where everyone lived together to form a small community.


    In this scheme, the gate of the shelter is designed to be a shielding door with the same level requirements as the civil air defense project built by the state. It is a reinforced concrete structure with a weight of more than three tons, wrapped with steel plate, plus supporting equipment such as poison filtering and air purification.


    According to the standard, this kind of gate structure is enough to resist the attack of nuclear shock wave, biological and chemical weapons and poison gas in wartime, giving people an incomparable sense of security.


    It''s just that the plan was abandoned at the beginning.


    No other way, Yanguo does not sell abandoned civil air defense facilities, especially at this critical moment when the end is coming.


    So later, according to the construction plan proposed by Chen Xin, we had to dig a cave at the top of the mountain, and then fill in the specially customized container houses to build shelters.


    Of course, the shelter built in this way is not as solid as the abandoned civil air defense project. However, considering that we are not facing such a terrible thing as nuclear war, this kind of shelter is enough.


    After all, we have to face nothing more than extremely cold temperatures and serious air pollution, which are much easier to deal with than nuclear radiation.


    And the shelter''s door is replaced by the three defense door that you can buy, instead of the shield door that you expected.


    Chen Xin didn''t think much about it. The three defense door he installed is 20 cm thick. If the two doors are locked from the inside, it''s really hard for a tank to remove the two doors.


    But now that the system has been upgraded, Chen Xin feels that he can make his door a little more solid and secure, and improve his defense.


    In Chen Xin''s idea, he will add the current two three defense doors to three, and transform the corridor into the refuge.


    The first door is naturally the outermost door of the shelter. After entering, it should be a disinfection room that can be cleaned and disinfected to clean and disinfect the personnel and vehicle equipment entering the shelter from the outside.


    Although there is no such deadly thing as nuclear radiation in the outside world, Chen Xin knows that the air outside is no less deadly than a nuclear bomb in front of his home after he knows that all the chemical plants have exploded.


    The decontamination room is absolutely necessary. The toxic and harmful substances that have been diffused into the air today may not be as lethal as nuclear radiation, but if they are accidentally contaminated, in this era, the medical conditions are far worse than those before the end of time, and the lethal degree may still be above nuclear radiation.


    Apart from other things, if you get drenched in acid rain, with today''s medical conditions, unless Chen Xin comes up with a medical cabin that can repair the body tissue, you will only live rather than die.


    Today''s acid rain is not the same as before the disaster. Before the disaster, the most important thing is to get red and itchy, cause allergy or lung disease, and need to see a doctor.


    But now the acid-base concentration of acid rain is much higher than that before the disaster. If it is drenched, it will really corrode the skin.


    After the decontamination room, Chen Xin is going to build a preparation room.


    The so-called servicing room is used to prepare travel equipment.


    Chen Xin plans to put all the protective equipment he may use when going out here, and move the garage up.


    In this way, it''s possible to get everything ready here and start from the preparation room without having to put the protective equipment inside the shelter again.


    This can not only make room for some crowded shelters, but also reduce the possibility of external harmful substances being brought into the shelters.


    Between the decontamination room and the preparation room, Chen Xin also plans to install another partition door to prevent harmful substances from entering the shelter through the air. At the same time, he can also install defensive weapons between the preparation room and the decontamination room.


    Although Chen Xin does not intend to harm others, he should be on guard.


    This is no better than the official refuge. All kinds of defense facilities are not as strong as the official refuge. In case the door is opened, he must have some means to protect himself against the enemy.


    The best way, of course, is to build a laser corridor like the one in the biochemical crisis movie. All the people who come here are dead.


    But Chen Xin is just thinking about it. Actually, it''s not that he can''t get it out, but it''s not cost-effective.So Chen Xin''s plan is to get a heavy machine gun right in front of the gate of the refuge. When an unidentified person or enemy comes in, he will shoot directly, which is convenient and fast.


    But now he doesn''t have heavy machine guns on hand. Chen Xin plans to replace them with bows and arrows.


    In a sense, the bed crossbow is even more powerful and effective than the machine gun.


    Even if it is transformed into a crossbow, its lethality is also unknown. Arrows can also be recycled, which is highly efficient, energy-saving and environmental friendly.


    With this in mind, Chen novice''s design is almost done.


    The first three defense door is used as the gate. After entering, there is the decontamination room. The decontamination room is connected with the servicing room, and the middle is connected with a short corridor. Two partition doors are installed. In the corridor, continuous fire heavy crossbows are installed. If someone is unidentified or is simply the enemy, shoot him a string of sugar gourds.


    After entering the preparation room through two partition doors, it is necessary to pass through a three defense door to enter the corridor connecting the refuge.


    At the bottom of the corridor is the last three defense door.


    With such protection, Chen Xin feels that the safety of his refuge can be improved a lot.


    In addition to protection, Chen Xin also plans to adjust the shortwave antenna and air vent inside the shelter, so as to avoid the danger of the enemy cutting off their own communication and injecting poison into the shelter through the ventilation duct.


    Should we even adjust the structure of the corridor? Make a floor concealed door and add another defense?


    Chen Xin thought it over carefully, but finally gave up the idea. It''s not impossible, it''s just unnecessary.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 85

    It''s really unnecessary to make the corridor into a floor door. After all, the front two doors have been broken through. It''s not significant to make the corridor into a hidden door. Can''t people find a door when they come in?


    Moreover, if the door is made into a floor door and the corridor structure is changed, it seems to be inconvenient to carry materials.


    Since we don''t plan to move to other places, the drawing of this gate will be finished.


    Looking at the CAD drawings made on the computer, Chen Xin can''t help feeling that this is the skill he learned by himself when he was looking for his first job after graduating from university. He hasn''t drawn any drawings for a long time.


    Originally, Chen Xin thought that after the end of the day, he would no longer draw drawings, but he did not expect to use this skill again so soon.


    But the reality is always more strange and complicated than we imagined. Maybe the fate will give you an unexpected surprise.


    Chen Xin couldn''t tell whether it was a surprise or a fright. He turned off his laptop again, put it at the head of the bed, checked the pistol in the bedside table and put it where he could easily get it. Chen Xin then put out the light in the bedroom, covered the quilt and closed his eyes.


    Tomorrow, he will upgrade the gate and make an oxygen generator for Mo Qingyan. There are still many things to do.


    But this sense of fullness is not bad for Chen Xin.


    When Chen Xin fell asleep, there was still a dim green light in the bedroom. It was the algae oxygen generator in the corner working.


    Chen Xin, who wakes up early, is already sitting in front of the desk. He plans to do a good job of the oxygen generator for Mo Qingyan first.


    Ding Ning sent enough materials to make oxygen generator. The only trouble is that although the glass she brought is as whole as possible, there are still many pieces of broken glass that need to be cut and spliced.


    In fact, if we can have a furnace to melt these glasses and then make them into the required shape, it is the best use of these broken glasses, rather than sticking them together with glass glue.


    However, for Chen Xin, he only needs glass as the raw material. With the help of the system, he can easily process the glass into whatever he wants.


    At this time, next to the workbench, the original broken glass has been reshaped into a tall circular cylinder, and Chen Xin is making the base.


    This kind of microalgae oxygen generator base is the key. The glass straight tube is only a container. It doesn''t matter what shape it is made of, but the ring straight tube is the most efficient for light utilization.


    A pipe and a vacuum pump need to be installed on the base to charge carbon dioxide into the circular cylinder to stimulate the photosynthesis of microalgae.


    Therefore, the chassis should be laid with annular pipe, and the carbon dioxide should be pumped into the pipe by air pump, so that the carbon dioxide can enter into the annular straight cylinder from the small opening on the pipe.


    It''s troublesome and dangerous to produce carbon dioxide with low purity, so Chen Xin directly uses ordinary air here to let the chassis absorb the surrounding air.


    As for the fill light, it is installed on the top cover, because the circular straight tube is placed vertically, the dead algae will deposit to the bottom, and the light transmittance will be relatively poor.


    With all kinds of tools on the workbench and the upgraded oxygen generator in the bedroom as a reference, Mo Qingyan''s oxygen generator can be made very quickly.


    After all, its structure is very simple, and its technology is relatively uncomplicated. With the assistance of the system, Chen Xin quickly made everything and assembled it together.


    Compared with the upgraded oxygen generator in the bedroom, Chen Xin''s hand-made one looks a little rough. Besides, it doesn''t make much difference. It''s enough for Mo Qingyan.


    So after the oxygen generator was finished, Chen Xin didn''t spend the survival to upgrade the oxygen generator, so he planned to give it to Mo Qingyan.


    Chen Xin took a look at the time and planned to have lunch first, have a rest and upgrade the gate in the afternoon.


    Although it is to confirm the upgrade, Chen Xin is not eager to finish it.


    There are not many things to do in the shelter every day. Chen Xin doesn''t want to finish everything at once and then become idle to play games.


    Of course, Chen Xin doesn''t really have nothing to do. The daily maintenance of the greenhouse can''t be saved.


    It''s just that as the crop goes into its growing season, all it needs is water and light to keep the greenhouse running.


    As for the control of common diseases and pests in greenhouses, Chen Xin is also very concerned.


    But I don''t know if it''s better to buy the seeds, or if the system has been upgraded. There is black technology in the greenhouse. At least so far, Chen Xin has not encountered any crop diseases and pests, and all the crops are growing healthily.


    The upland rice he planted has now entered the long panicle stage. From the young panicle to heading, this process will last about 30 days. According to the growth cycle, in a few days, these upland rice should enter the seed setting stage and start heading.It has to be said that Chen Xin had never planted rice before. After he really started planting upland rice, he realized that the so-called "two seasons a year" of upland rice was only because the environment and climate did not allow it.


    If it''s in a greenhouse, let alone two seasons a year, it can grow three seasons a year.


    In this way, Chen Xin found that after he expanded the greenhouse to 200 square meters, if he used half of the land to grow upland rice, he could harvest about 600 Jin of rice a year. Although not much, it was enough to eat as a staple food, at least to maintain Chen Xin''s consumption.


    Even if Chen Xin upgraded the greenhouse, and upgraded the current single-layer hydroponic cultivation to multi-layer hydroponic cultivation, all of which were used to grow vegetables, and the land was used to grow upland rice, his output could even afford one or two more people.


    As for further upgrading, developing a fish vegetable symbiotic circulation system and animal breeding, and simply raising more fish, chickens, rabbits and other birds, we will be able to maintain more life needs.


    What''s more, Chen Xin can now trade vegetables for food from the special police force.


    Although the food Qin LAN used to eat in those refuges was not flattering in terms of taste or taste, at least it was food. It was edible, and it was still a good food nowadays.


    When it comes to food, Chen Xin thinks about it and decides to eat Qin Lan''s mushroom stewed rat meat for lunch today. As for the canned meat from Mo Qingyan, he can keep it for a while.


    After all, there is some mouse meat to eat now, but pork is not sure when it will be eaten again.

    "Ordinary shelter entrance"


    "upgrade scheme 1: increase the thickness of the protective door, enhance the defense of the shelter entrance, add biochemical radiation decontamination room, upgrade the required survival point of 1500"


    "upgrade scheme 2: increase the screen door, increase the partition door, add the servicing room, upgrade the ventilation system air inlet of the shelter, upgrade the required survival point of 1350"


    look at these two options Chen Xin, who has already obtained enough materials from the special police force, did not consider the more appropriate plan, so he chose to upgrade all of them.


    For Chen Xin, who can now obtain 15 survival points a day, with sufficient materials to reduce the consumption of survival points to 10%, the consumption brought about by the upgrade mode of selecting all two schemes is already within his range.


    It''s just that Chen Xin didn''t expect that an oxygen making box that didn''t consume a few survival points could provide him with two survival points every day, which is beyond Chen Xin''s expectation.


    However, this is not hard to understand. After all, his upgraded algae oxygen generator not only produces oxygen, but also uses the biomass produced to ferment to produce biogas for fuel cell power generation.


    That is to say, this equipment is equivalent to the functions of oxygen generator, biomass incubator and fuel cell. It has greatly improved Chen Xin''s current living conditions, so it is understandable that he can obtain more survival.


    After choosing all the upgrades, the gate of the refuge is upgraded to the way he drew on the design drawing according to Chen Xin''s idea under the power of the system.


    Strong and heavy protective door, decontamination room for radiation and biochemical decontamination, servicing room for parking cars and sorting equipment, defense corridor with Heavy Crossbow


    Today''s refuge is like a real doomsday refuge, with a solid and reliable defense.


    He drove up the car that was originally parked below and parked it in the servicing room. Chen Xin also brought up the equipment that he might use when going out.


    Hanging heavy protective clothing in the wardrobe of the preparation room, all kinds of equipment and materials needed to be carried out are also stacked in order. Chen Xin looks at the neat things in front of him with a sense of satisfaction and pride.


    It''s like the sense of accomplishment you get when you play in my world and finally build a cabin that makes you feel safe and secure.


    And different from the game, this is the real world, this is the real refuge, this is the real refuge that can protect Chen Xin''s safety.


    Through the renovation and upgrading of the entrance to the refuge, Chen Xin also moved the vent and shortwave antenna that originally led to the hillside to the top of the entrance and put them in a small bunker made of thick reinforced concrete.


    This bunker is not big, just a small space. It is located above the decontamination room at the entrance of the refuge. It is similar to the machine gun blockhouse in war games.


    This is not a machine gun bunker, although in a sense, as long as Chen Xin sets up a machine gun here, it can really serve as a machine gun bunker.


    However, the actual function of this small bunker is to protect the shortwave antenna and air vent moved here. It''s not true that Chen Xin wants to build a machine gun bunker here.


    Although it is likely to become a defense facility in the future upgrade, now it is just a shelter for short wave antennas, and at most it will play a role of ventilation.


    The outside of the shelter is covered by the soil of the mountain itself, leaving only a gap about palm wide. It is impossible to enter the shelter from the outside, but only through the channel reserved inside the shelter.


    Compared with the shortwave antenna which was just covered by camouflage cloth and placed directly in the open air, the shortwave antenna under the protection of such a small shelter is much safer. Even if it is found, it is difficult to destroy the antenna which is placed in a solid shelter.


    As for the influence of the bunker on the antenna signal, it''s not without it, but it''s not serious. At least Chen Xin tried it, and he can receive the external signal and contact others smoothly.


    After the original vent was transferred to the shelter, there were new changes. Not only the protective cover and grille filter were added, but also an overpressure automatic exhaust valve was added after the vent pipe entered the shelter.


    This is the ventilation equipment that will be used in civil air defense engineering. The principle is to use the air pressure difference between the inside and outside of the shelter to form a seal, block the invasion of toxic and harmful air outside, and discharge the air inside the shelter to ensure the ventilation cycle.


    Although it sounds a little complicated, the structure of this thing is very simple. With it, there is no need to worry about external toxic and harmful substances entering the shelter along the ventilation pipe.


    Qin LAN and several special police officers are holding guns at the gate of an old shopping mall in the urban area.


    This is a large shopping mall in the city. There is an underground supermarket and a parking lot. Before the disaster, it was planned to be a small shelter, in which about 5000 people living in the surrounding community lived.


    The plan of this kind of small shelter was originally intended to let some people escape the doomsday disaster here, and connect other shelters with passageways after the disaster, so as to be used as an underground residential area.But now because of the deterioration of the environment and the temporary inability of oxygen generation equipment to supply small shelters, the city government can only transfer people to other medium-sized shelters and temporarily seal up the small shelters.


    It is planned to wait until the medium-sized shelters are connected to this area, and the oxygen generation equipment is surplus, and then it will be reopened.


    Qin LAN, they are here to help these people transfer, in addition to them, there are city government staff in charge of the transfer.


    The second batch of oxygen generating equipment was brought in not long ago, but this batch is much less than the previous batch, with only four small biological oxygen generating machines.


    Of course, two of them were transported to Binhu community and Polytechnic College, two medium-sized shelters that had not been assigned oxygen generation equipment before, while the remaining two were given to the shelters where the armed police were located, and the other one to the factories.


    It is also because of the lack of oxygen production equipment that the municipal government decided to temporarily abandon all the small shelters and all the population diversion channels and medium-sized shelters.


    Although there are only a few thousand people in the small shelters, the relocation of thousands of people is not an easy job. The staff sent by the city government are already in a mess, and they need to deal with all kinds of problems.


    Qin LAN stands on the shooting position of the armored roof, holding his own sniper gun. His eyes are constantly patrolling the crowd, searching for possible dangers.


    Now in this case, anything can happen, Qin LAN, they must put an end to any possible criminal behavior, to avoid evolving into a group event.

 Chapter 87

    Even before the disaster, it is a great thing for the state or the government to transfer thousands of people at a time, which requires strong organizational ability and executive power. As for various possible security problems, it is a headache.


    Now it''s no better than before. The dim environment is illuminated by the searchlights of several police cars around. Under the snow-white light, those faces are full of fear of the unknown and worry about their own future.


    It''s not like in the past, when the government said relocation, everyone was willing to believe it, because the image that the government has always set up makes people willing to believe it.


    But at the end of the day, the threat of disaster has already made people panic. They are worried about how to live their next life every day, and now they have to move from the safe haven. This is a great blow to these people.


    If it wasn''t for the efforts of the staff of the municipal government and the suppression of the special police nearby, it would have been chaotic.


    However, even so, there has been a commotion and uneasy whispering among the crowd.


    There are only more than 5000 people in this shelter. The city government has organized about a dozen buses to transport them away in batches. This group of people waiting is the third batch.


    About 50 people can be transported by one car, and one tenth of them can be transported by one trip, so only more than 500 people are waiting at the door, and the rest are still in the shelter.


    This is also for the sake of safety. After all, 500 people are much easier to manage than 5000 people, and there is no need to keep the rest of them waiting all the time. They are easily restless, and those who are waiting at the end are easy to get sick.


    Now the temperature is very low. Although the temperature below zero will not freeze for a while and a half, it is very difficult for people to stand outside for a long time.


    Especially now the air is particularly poor. With the low temperature and no rain, the toxic and harmful substances and dust in the air can not be reduced. If there is no protective equipment in outdoor activities, it is impossible.


    Even the swats with full protective equipment need to change shifts every once in a while.


    However, these people did not wait long, a dozen buses had already come over and stopped in front of them.


    Seeing the arrival of the bus, the waiting people have a sense of relief and peace of mind.


    Although the future is still uncertain, but at least now they can settle down, at least the government did not ignore them.


    Looking at the waiting people boarding the bus one by one under the guidance of the city government staff, a special police member in the armored car where Qin LAN is, asked Li Tou, who is in charge of the team: "Li Tou, is this the third batch? How many people have been sent away? "


    "Well, this batch should be more than 1700." Li nodded his head.


    For each group of people sent away by the municipal government, the number of people will be counted and reported to avoid omission.


    Hearing Li Tou''s reply, the Swat member couldn''t help feeling: "is this the seventh refuge? These people are pathetic


    "What can I do? If I don''t move it, I''ll suffocate!" Li Tou naturally understood what the Swat members around him were feeling, but there was no way to deal with this kind of thing.


    Hear their words, Qin Lan also can''t help but feel sad, really don''t move will suffocate.


    As a matter of fact, the city government was forced to make the decision to move. With the further decline of the temperature, the problem of hypoxia or carbon dioxide poisoning appeared in all shelters.


    If all shelters did not attach great importance to this problem and prevent it in time, I am afraid that many people would die as a result.


    However, even so, there are still many people died because of this, most of them are elderly people or children.


    So the city government decided to move all the people from the small shelters to the medium ones.


    After all, the three major refuges and six medium-sized refuges already have oxygen generation equipment, which can provide the most basic survival guarantee for the people living in them.


    Although this will bring a lot of troubles and problems, when more people can survive, the city government will not choose to give up the people in these small shelters and let them live and die.


    This topic has not been discussed. After shaking their heads and sighing, the SWAT team members who spoke looked at the buses full of people ready to leave. They could not help but worry: "in this weather, I''m afraid these buses will finish this mission. Should all the air filters be changed?"


    "It doesn''t matter. Anyway, the buses are useless for the people who transport these shelters." Li Tou didn''t pay much attention to this. Although it''s hard to get auto parts under the current situation, these buses are useless after transporting the people in these shelters.


    There are only 11 small shelters in the urban area. Hospitals, armed police forces, underground planting bases and factories will not be moved. Therefore, there are only seven small shelters to be relocated, and this is the last one.Listening to the discussion between Li Tou and the special police member, Qin LAN is naturally thinking about this problem. It''s useless for the bus to finish the task, but it doesn''t mean that there is no need to use the car.


    Apart from other things, the daily patrol of their special police force also causes losses to the vehicles, not to mention that Qin LAN has to go to Chen Xin''s shelter once a month.


    Although these auto parts were also stored before the disaster, if they can''t be replenished all the time, all the vehicles will be lost sooner or later.


    Although the vehicles of their special police team have been protected, they have specially replaced the paper dry air filter with the inertia oil bath air filter, which is more suitable for the harsh environment and is not easy to wear, but the consumption of air filter is still not small.


    However, with the recovery of various industrial facilities by the state, the supply of these things is gradually restored. However, at present, the consumption is still greater than the supply, and the previous material reserves must be consumed.


    Thinking of this, Qin LAN can''t help thinking that Chen Xin''s car hasn''t been specially protected. The air filter element on his car may not be replaced. Maybe he can add this to the list of materials exchanged with Chen Xin later?


    This idea gave Qin LAN a lot of inspiration. Since the car consumables can be listed in the list, other things such as generator repair parts can be used to exchange vegetables with Chen Xin.


    It has to be said that it may not matter if everyone can''t eat vegetables, but for the SWAT team, it has become their most anticipated thing to be able to eat fresh vegetables from Chen Xin every month, even though these vegetables are only enough for a few days in a month.

 Chapter 88

    In the preparation room, put on the protective clothing and buckle the protective mask on his face. Chen Xin arranges his own equipment.


    Originally, Chen Xin planned to let Qin LAN bring the oxygen generator to Mo Qingyan when she came to exchange materials with him, but out of worry about Mo Qingyan, Chen Xin decided to send it to her by herself.


    The whole oxygen generator has been crammed into the compartment of the SUV with the back seat down, and it has been bundled to make sure it doesn''t roll just because it''s round.


    After all, it''s made of glass. If it''s bumped, it''s broken.


    Chen Xin''s equipment is still flashlights, folding climbing sticks, which he used when he went out last time, but this time his pistol was changed from the one he made to the one he bought from Qin LAN.


    Originally, Chen Xin considered that he was going to the city and didn''t plan to bring a gun, but after hesitating for a moment, he put the gun on him. He was responsible for his own safety.


    In addition to these things, Chen Xin also brought a bottle of oxygen.


    This is the bottled oxygen he used to store. The quantity is not much, and there is no oxygen when he runs out. However, considering that the oxygen content outside is lower now, and there may be the risk of hypoxia, he still put a bottle on his body, so as to avoid having no idea in case of insufficient oxygen.


    After sorting out the equipment, Chen Xin opened the door of the upgraded shelter and drove the car out.


    When Chen Xin turns around and closes all the doors, he sets out to deliver the oxygen generator to Mo Qingyan.


    In the rear-view mirror, the gate of the shelter is much more decent than before. It is no longer the appearance of digging a hole and burying the door, but a strong gate reinforced with cement.


    In fact, it''s all reinforced concrete, not just cement. Although it looks conspicuous, it''s not without benefits.


    Of course, firmness is the most important. In addition, it can also facilitate drainage.


    Although the main precipitation has turned into snow as the temperature gets lower and lower, the solid cement floor is easier to drain and maintain than ordinary mud.


    Driving to the city, Chen Xin had to turn on the lights this time, instead of turning them off as before.


    Because the road has become a little damaged compared with when Chen Xin came out, and with the rain in recent months and the meteorite falling from time to time, there are a lot more debris on the road than when he went into the city last time.


    This slows Chen Xin''s progress a lot. The car is equipped with a glass oxygen generator, which is too bumpy and easy to be damaged. In order to protect the oxygen generator, Chen Xin can only walk slowly on a relatively smooth road.


    When Chen Xin entered the urban area before, most of the buildings in the urban area were just burned, but the overall structure was still there.


    However, when entering the urban area this time, Chen Xin clearly saw that some houses had collapsed.


    That is the collapse caused by the impact of meteorites. As time goes on, the dust and meteorite debris floating in the sky will gradually fall. The larger the volume, the faster the fall. Now the larger debris is falling.


    In a sense, this is also a good thing. As the debris keeps falling, the dust clouds in the sky will not be so thick. After one to two years, the earth will gradually return to sunshine.


    For today''s human beings, one or two years from no light to low light environment, can greatly improve the survival status of human beings.


    However, it will take a long time to return to normal light. The dust will cover the sky for at least several decades, at least two generations.


    As for the restoration of the earth''s ecology, it will take a longer time. The earth''s ecology may not be restored for hundreds of years.


    For the earth, perhaps this is just a short moment, a tiny moment in the earth''s billions of years. Although this moment has caused great damage to the earth''s ecology, it is still insignificant for the whole earth.


    However, for human beings, this is a doomsday catastrophe that lasts for generations and affects the survival and development of the whole civilization. We have to say that human beings claim to be the masters of the earth, but in fact, compared with the whole earth, human beings are so small and vulnerable.


    after arriving at Mo Qingyan''s house, Chen Xin called her on the radio as before.


    Compared with Chen xinlai''s last time, Mo Qingyan''s home has obviously been strengthened and rebuilt. There is a circle of barbed wire on the wall, and the iron door can be seen to be reinforced. Even the original doors and windows of the shop front have been nailed to death, and simple roadblocks made of triangle iron and wood have been put on the iron door in and out of the backyard.


    Although some of them are conspicuous, they can be regarded as a security guarantee. At least it''s not so easy for someone to do something to Mo Qingyan''s family.


    After receiving Chen Xin''s call, Mo Qingyan and Mo Qingxin open the iron door together. After removing the roadblock, they signal Chen Xin to drive in.


    After Chen Xin drove the car in, the Mo sisters quickly moved the roadblock back to its original position and closed the door again.As before, he drove the car into the elevator and went down to the shelter with Mo''s sisters. Chen Xin got out of the car and took off the mask on his face.


    "Ingredients, your protective clothing is good! Where did you buy it? Why didn''t I see you last time? " Mo Qingyan looks at Chen Xin''s protective clothing and can''t help showing her envy.


    Although she also has protective equipment, it is obviously not as good as Chen Xin''s very professional protective clothing.


    What''s more, what she has are protective masks, tactical ponchos and anti cutting gloves, which are far behind Chen Xin''s almost head to toe protective clothing.


    Hearing Mo Qingyan''s question about her protective clothing, Chen Xin lifted the hat on her head, and then replied, "I changed it myself. If you are envious of long Niang, you can give me the material, and I''ll change it for you."


    "Oh! Did you make it yourself? Well done! What materials do you need? Help me and Xiaoxin to make one later! " After hearing Chen Xin say that she can help make one, Mo Qingyan and Chen Xin are not polite.


    Chen Xin nodded and agreed that it was just a piece of protective clothing. Even if survival points were needed to upgrade, it would not cost a few survival points if Mo Qingyan provided materials.


    "By the way, this is an oxygen generator made for you. I told you about the oxygen problem before. I was worried that you could not deal with it, so I made one for you." Chen Xin, of course, did not forget the purpose of his visit today. He opened the trunk of his car and moved the oxygen generator out of it: "in the case of constant electricity, this machine is enough for you and Xin Xiaomei."

 Chapter 89

    "Ingredients, you can even make this! How awesome Mo Qingyan looks at the oxygen generator that Chen Xin has removed from the car and praises it sincerely.


    When Chen Xin told her to pay attention to the problem of oxygen, Mo Qingyan also heard from Chen Xin how to make a simple oxygen generator by herself, and even planned to make one with her sister Mo Qingxin, but only when she got to it did she find that it was not something that could be made casually.


    In the face of Chen Xin''s oxygen generator, Mo Qingyan was not only impressed by Chen Xin''s practical ability, but also moved.


    So she said to Chen Xin half jokingly, "ah Xin, you take this kind of thing, how can I exchange it with you? You can''t empty my wine cellar if I trade with you? Would you like me and Xiao Xin to have a good time with you? "


    Hear Mo Qingyan say so, Chen Xin has no what to say, the face of Mo Qingxin on one side immediately red up.


    Although Chen Xin and Mo Qingyan didn''t mind this kind of joke before, it really made Mo feel very shy and embarrassed to say it in person.


    "It''s OK to have a good time. I don''t have such an idea now." Chen Xin shook his head and refused Mo Qingyan''s proposal: "give me two bottles of your treasure, and give me two cases of wine and two cases of cans. As for saying that I really want to have a good time, wouldn''t it be better for you two to move to my place? "


    Even if something really happens between him and Mo Qingyan, it won''t affect their relationship, but Chen Xin still wants to stick to the bottom line.


    "Lying trough, I can''t see the ingredients. Do you still think of the golden house?" Mo Qingyan heard Chen Xin''s refusal, and was not sure whether he was glad or sorry, but soon he was very exaggerated and make complaints about Chen Xin.


    Chen Xin didn''t go on either. He just helped Mo Qingyan install the oxygen generator. After it was filled with water, he said to her, "the oxygen generator needs continuous power supply. If there is no light, the algae inside will not photosynthesis, so we must keep power supply. Long Niang, do you have a backup power supply here? "


    "Yes, I designed a battery pack when I built the shelter. It can be used for three days when it is fully charged, and I also have a generator here." Mo Qingyan nodded, indicating that there was no problem with the electricity.


    Hearing Mo Qingyan''s words, Chen Xin nodded reassuringly, pouring water into the oxygen generator and said: "the water in the oxygen generator doesn''t need to be changed often, but the algae deposited at the bottom should be cleaned to avoid blocking the bottom nozzle."


    Listening to Chen Xin''s explanation of the precautions for the use of the oxygen generator, Mo Qingyan nodded her head and asked Mo Qingxin to record it carefully.


    However, while recording Chen Xin''s notes, Mo Qingxin also asked with concern: "ah Xin, I''ve written down what you said, but where can we get algae? In this situation outside, are all the algae dead? "


    "Algae don''t die so easily. There should be some surviving algae." Chen Xin is naturally prepared for this. After he smiles at Mo Qingxin, he takes out a bottle of green liquid from his car: "but you don''t need to go outside to find it. I''ve already prepared it for you. It''s water from my own oxygen generator. It''s rich in algae. When it''s poured into your machine, it will reproduce by itself."


    "Self breeding? Don''t you need anything else? " Mo Qingxin looks at Chen Xin pouring a bottle of green liquid into the tank of the oxygen generator and asks curiously.


    "Normal use should also add nutrients to promote algae reproduction, but the conditions are limited Chen Xin shook his head helplessly, but at the same time explained: "even if it is placed normally, after a long time, the eutrophication of the water body will naturally produce algae, so you don''t have to worry about the propagation of algae.


    If the algae inside really don''t grow well, long Niang, you can go to a LAN or Xiao Ding. I heard them say that this kind of algae oxygen generator is also used in the official refuge. They should have the nutrients for algae. Just get some. "


    When Qin Lanzhi came to deliver the goods, he did mention it with Chen Xin, because he was also using the algae oxygen generator, so naturally he wrote it down.


    Hear Chen Xin say so, Mo Qingyan of one side hastily nods to answer a way: "I know, turn head I will ask a Ning."


    After turning on the power and letting the oxygen generator run, Chen Xin clapped her hands and said to Mo Qingyan, "OK, in a day or two, it should turn green and oxygen will be produced."


    Although he said that, Chen Xin has no idea whether he can generate enough algae in one or two days.


    After all, the system of his oxygen generator was upgraded directly, and the algae in it propagated rapidly after the upgrade. It took only one day to dye the water dark green, and the efficiency was far faster than that of the algae under normal conditions.


    However, algae are really easy to grow. If a puddle is left alone, the water will turn green in a few days. So Chen Xin is not worried that Mo Qingyan''s oxygen generator will not work properly.


    Seeing that Chen Xin had installed the oxygen generator, Mo Qingyan took the initiative to say to him, "it''s hard for you, ah Xin. You can stay at noon and go back after dinner.""Ah? oh Good Chen Xin didn''t know why he was stunned for a moment. After Mo Qingyan yelled, he regained his mind and agreed to her proposal to stay for lunch.


    Although Chen Xin agreed, while waiting for Mo Qingyan to cook, he always seemed to be out of his mind, as if he was thinking about something.


    I noticed Chen Xin''s state, but Mo Qingyan and Mo Qingxin didn''t say much. They just asked with concern. Seeing that Chen Xin didn''t have any problems, they didn''t care any more.


    For lunch, what Mo Qingyan brings out is still the emergency food reserved before the disaster. In addition to hot food, there is also a can of pork and cabbage Chen Xin exchanged for her.


    I have to say that this kind of thing that can be stored for several years and decades is really very useful in the current environment.


    Compared with storing rice, frozen meat or dehydrated vegetables and so on, emergency food can be kept for a longer time, but also has the advantage of saving fuel and water.


    After all, today''s emergency food is self heating, which can be heated by one mouthful of water. Compared with raw materials such as rice, which need to be boiled with water, it is convenient and reliable in the doomsday environment.


    The raw materials such as rice and frozen meat need to be cooked if they want to enter the mouth. They need to consume precious drinking water and fuel, and their self preservation also depends on storage.


    Rice is a little better. Ingredients like frozen meat can only be preserved for a long time in a low-temperature environment, which is far less durable than emergency food that can be stored in a place.

 Chapter 90

    After lunch at Mo Qingyan''s place, Chen Xin drove back to his refuge without staying.


    But along the way, his mood was a little excited, and his manner was also a little strange.


    After returning to the shelter, he parks the car in the preparation room, closes the door again, and takes off his equipment. Chen Xin then quickly returns to the shelter and sits down on the sofa in the living room, calming down his excitement caused by the unexpected harvest.


    "Help others to improve their living conditions and get 100 survival points"


    "help others to improve their living conditions and get 100 survival points for the first time"


    "help 2 people to improve their living conditions and get + 2 survival points every day"


    the system without any sense of existence suddenly brushed three prompts in front of Chen Xin, which made it difficult for Chen Xin not to notice these information.


    The sudden increase of 200 survival points and daily gain of survival points + 2 is undoubtedly a huge surprise and a rich harvest for Chen Xin.


    He helped Mo Qingyan make an oxygen generator. The survival points he put in were only a few of the material processing fees, but the harvest was equivalent to the survival points he got in half a month.


    With such a huge return, Chen Xin couldn''t help wondering whether he should make more oxygen generators for others.


    After all, among the three tips, except that "helping others to improve their living conditions for the first time" belongs to achievement and cannot be obtained repeatedly, the other two can be obtained repeatedly.


    Although "helping others to improve their living conditions" is a one-time income, the system does not say that it can only be done once.


    Chen Xin''s brain is not stupid. The oxygen generator can improve the living conditions. Can that kind of greenhouse be used? What about the ventilation system? What about biogas fuel cells? What about stronger shelters?


    To improve the living conditions of a refuge is the same as to improve the living conditions of Chen Xin''s own refuge. It is a project that can be continuously improved.


    It also means that he can get a lot of survival, as long as he is willing to help others improve their living conditions.


    By improving the living conditions of others, we can also gain more daily survival, which obviously greatly improves the speed of Chen Xin''s survival.


    Through these three tips, Chen Xin seems to see a huge amount of survival coming towards him, and the power armor and machine armor that he expected to appear after the upgrade of the refuge also seems to be slowly coming towards him, and even more to him.


    "To improve the living conditions of others, according to the head count, one person is a little more every day. If I can get the official shelters to write such a line, ten thousand people will be ten thousand a day!" Chen Xin talked to himself excitedly. Although this is only his fantasy, it does not prevent him from looking forward to a better future.


    However, there is a great possibility. As long as Chen Xin can improve the living conditions of a large refuge, according to the current prompt given by the system, a person can get a little increase in survival points every day, which is enough for him to get a lot of survival points according to his head.


    Of course, it''s not easy to do that.


    The big refuge is not like the small one. Chen Xin can upgrade anything to improve his living conditions.


    For the great refuge, if we want to improve the overall living conditions, it is undoubtedly necessary to upgrade the whole refuge.


    This obviously requires a lot more survivals than upgrading small shelters to achieve the goal.


    It''s like the oxygen generator in the official refuge, with thousands of biological facades, which Chen Xin can''t make.


    Even if we use survival upgrade, the survival consumed by such large-scale equipment may be enough for Chen Xin to upgrade his refuge as a whole.


    All in all, helping to improve the living conditions of the great refuge can bring huge returns, but it is not something Chen Xin can afford now.


    However, this also gives Chen Xin another way of thinking. It doesn''t affect the big shelters. There are still small shelters to use!


    There are quite a few people who build their own shelters in the survival group formed by Chen Xin and Mo Qingyan. According to the statistics after the disaster, there are more than 20 private shelters for all the group friends.


    Although in recent months, a small number of group friends abandoned their shelters and went to the official shelters with supplies because of inadequate preparation or the original plan to survive the disaster, there are still 19 private shelters left.


    Five of them are in Linshi, two are in Sanzhen, and the remaining 12 shelters are in this city except Chen Xin and Mo Qingyan.


    In the previous routine communication, everyone''s situation was fairly good, there was no big problem, and the material reserve was relatively sufficient, except for the exchange of needed goods, there was no need to even exchange materials.


    But now for Chen Xin, these ten refuges are the survival of baihuahua!


    It doesn''t even need more. Each refuge will send an oxygen generator, which can provide Chen Xin with 1000 survival points. As long as he gathers some more, he can upgrade the refuge with materials.Thinking of this, Chen Xin can''t help but get excited. He has already seen the powerful upgrade function of the system. If the refuge can be upgraded as a whole, it will undoubtedly bring him better living conditions and enable him to survive in this doomsday.


    But now the temperature has dropped to zero, and it will continue to drop. If we are not prepared, the coming extreme cold will be enough to freeze anyone who is not prepared enough.


    As for why helping others improve their living conditions can lead to survival, Chen Xin doesn''t find it strange.


    Human beings are social social animals. Helping others can be regarded as improving the overall social environment. When the overall social environment is good, the living conditions of individuals will naturally be improved.


    After all, it''s obviously easier to survive in the tough environment of doomsday than alone.


    It''s like the shelters that survived in the end of the ice age. If we don''t help each other, how can we survive better in the end?


    If Chen Xin doesn''t have a system, I''m afraid he should be eager to exchange materials with others now?


    After all, although we all store materials according to the same list, everyone can purchase different materials and build different shelters.


    Just like he and Mo Qingyan, who have vegetables and Mo Qingyan has wine and canned meat, the exchange between them can just complement each other in resources to a certain extent.

 Chapter 91

    It''s the same with other refuges. There are always some things that you have, I don''t have, and I have things that you don''t have. Trading and exchanging are the key to everyone''s survival.


    However, Chen Xin took the road of the special police team and could get more and more kinds of things from the special police team, so he didn''t exchange materials with other shelters.


    However, now that he knows that he can survive by helping others improve their living conditions, Chen Xin will not miss the opportunity to communicate with other refuges.


    During the regular communication time in the evening, Chen Xin first raised the issue of oxygen again. When he told Mo Qingyan about this issue, he also informed other group friends at the same time. So at this time, Chen Xin raised it again, and other people naturally responded.


    "Fortunately, you reminded me of this. Before I went out to search for materials, I almost had no oxygen cylinder."


    "But even if you know about it, there''s no good solution, right? My family relies on the plants in the greenhouse for photosynthesis to provide oxygen, and now I dare not turn off the lights. "


    "I''ve heard that it seems that the state has prepared oxygen generators in the official shelters, so now the city government is transferring the population of small shelters to several large ones. Do we also... "


    The group friend''s words did not finish, but his meaning was clearly expressed.


    If you can''t make it, go to the official shelter.


    This is not a choice that is hard to accept or a last resort. Before, several companions who could not survive had chosen this road. Now it is quite natural for someone to put forward the same idea.


    For Chen Xin, this is naturally the effect he wants, so he hastened to say: "I have a solution to the problem of oxygen! I''m able to make a simple oxygen generator. I''ve sold one to longniang before. If you need it, I can do it for you. "


    "Writer, can you make an oxygen generator?"


    "Really? Writer, if you can do it, I want one


    "I want one, too! What do you need for a deal? "


    "You are my half brother from today on."


    "Writer, what materials do you need to make an oxygen generator?"


    Chen Xin''s words immediately aroused strong repercussions. After all, for these survivors, to be able to obtain an oxygen generator will undoubtedly help them survive better in this last life.


    Although there is still a way to go to the official shelter, who wants to go to the official shelter to struggle for survival if there is a comfortable private shelter to live in?


    Before the end of the day, they did not know what conditions the state built shelters were. Although the conditions provided by the state were not bad, if they had a choice, they did not want to live in the official shelters.


    Although we didn''t say it, we all know something about the darkness of people''s hearts in the end of the world by the blessing of so many films and TV works before the disaster.


    In a sense, the more people there are, the more problems they are likely to have in this last world.


    At first glance, it seems to contradict unity and cooperation in order to live better, but in fact, the two do not conflict.


    Less people mainly face the threat from the external environment, while more people mainly face the internal contradictions.


    Faced with the threat of external environment, if there are too few survivors or just one or two people, they can do little.


    Besides, it is difficult for a person to build a strong shelter. If there are enough people, they can even send people to collect materials while building the shelter.


    But there is also the problem of more people. Everyone has his own ideas. It''s OK to have fewer people. We can discuss it.


    But when there are more people, there are more ideas. It''s impossible for most people to think about the same thing. If they think about it in one place, it''s more dangerous to have more people than to have fewer people.


    So at the beginning of the end of the world, when Chen Xin and his colleagues discussed the construction of the refuge, they actually found that the most reliable and appropriate way to survive was to build a community like existence, gather all the people together, divide the work in a small team, work together, and face the threat of the doomsday disaster.


    Unfortunately, unlike the federal government, Yanguo can sell abandoned missile silos and be transformed into refuges by the rich.


    Their plan was abolished from the beginning, and they could only build private shelters one by one.


    Although private shelters are more comfortable to live in than official large shelters, they are still lacking in supporting infrastructure.


    Chen Xin didn''t think well about what he wanted to exchange with the oxygen generator, because for him, giving the oxygen generator to others and getting survival on his own is his biggest gain.


    But it is obviously impossible for him to tell others that he wants nothing and gives them an oxygen generator for nothing.


    The story of Sheng mien fighting against Mi Qiu is the ancient wisdom of Yan Kingdom since ancient times.


    "To make an oxygen generator, we need glass, vacuum pump and fill light. I have materials here. You don''t have to worry about them." Chen Xin didn''t plan to let others provide materials, but he didn''t plan to give them away: "as for what to exchange, let''s see what you have. If I can use it, I''ll exchange it. I can''t really suffocate everyone.""Don''t worry, I won''t let you suffer. I have some fresh fish here. Do you want to eat fish?"


    "A few fish want to change the oxygen generator. Are you too stingy? Writer: did you buy your SUV in my shop? Now the environment is so bad, let me do a major maintenance for you! "


    "It''s getting cold. Do you need a heater? I have a spare heater here


    As soon as Chen Xin''s words came to an end, everyone immediately talked about his exchange terms. They wanted to impress Chen Xin and let him make his own oxygen generator first.


    After all, even if Chen Xin has the ability to make an oxygen generator, he is alone, and the production efficiency is certainly not high. If Chen Xin works slowly, some people will get it first and others will get it later.


    In this matter of life and death, no one wants to lag behind.


    Chen Xin can only feel helpless and funny about this, but he has not seen such a lively scene for a long time.


    Most of the time after the end of the day, he was alone. At this time, the lively atmosphere made him feel a bit more alive, and made him feel that he was not alone.


    However, in listening to the various exchange materials reported by everyone, Chen Xin heard something that interested him.


    "I use the medical box to exchange with you. There are all kinds of commonly used drugs, medical supplies, and a set of simple surgical instruments, which are enough to deal with all kinds of common diseases and trauma."


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 92

    For Chen Xin, a medical box with a complete range of drugs and full of various medical supplies is really what he needs.


    Although Chen Xin also has a medical kit and a field first-aid kit, it''s just an ordinary home medical kit and field first-aid kit.


    Although Chen Xin tried to match as many kinds of drugs as possible before the disaster, they were basically some common family drugs such as cold drugs and anti-inflammatory drugs.


    Certainly not as good as the professional medical box, especially the group of friends who provided the medical box specially said that they would prepare enough medicine and a complete set of simple surgical instruments in it.


    The former nickname of this group friend in the survival group was "doctor", and his own occupation was indeed a doctor, but he was not a doctor in the hospital, but opened a clinic himself.


    When the friends in the survival group discussed what kind of medical survival materials to prepare, he also provided a lot of advice and help from a professional point of view. He also got some drugs and medical supplies through his own relationship.


    He helped to make up the medicine in Chen Xin''s medicine box.


    Therefore, when the "doctor" mentioned that the oxygen generator could be replaced from Chen Xin with a medical box containing various drugs and simple surgical instruments, Chen Xin just gave him a little consideration and agreed.


    In fact, it has something to do with Chen Xin''s hope of getting himself a medical room.


    When he first got the survival system, he had tried to use the medical kit and first aid kit to separate a medical room, but obviously there was only such a simple tool, no matter how versatile the system was.


    Now "doctors" say that they can provide more professional medical equipment, which naturally makes Chen Xin very interested and interested.


    If we can make use of this wave of medical equipment to make out the medical room, for Chen Xin, it is a great good news and the improvement of the quality of life.


    The doctor''s refuge is located in the old urban area of the city, near Dongting Lake.


    It used to be an old urban area. When the mayor was in office, the area was upgraded and transformed into a gray tile and white wall building with the style of Jiangnan Water Town. The area was redeveloped and became a tourism commercial street.


    Before the disaster, the doctor''s home was here, and his clinic was also here.


    His home is not a new house after reconstruction, but an extra layer of exterior decoration after renovation of the old house.


    But even so, the original gray tile white wall is also very good-looking, but now it is also burned in pitch black, looks like ruins.


    By the time Chen Xin arrived, the "doctor" was already looking forward to it.


    "Writer, you are here at last!" Seeing Chen Xin''s appearance, "doctor" hastened to welcome him.


    "Long time no see, doctor." Chen Xin greets the "doctor" and stops the car at his door.


    "Doctor"''s home is not as wide as Chen Xin and Mo Qingyan''s. There is a place to drive cars into the shelter. His home is just a small building facing the street, with a half basement structure on the lower floor. In addition to the basement he dug when the block was rebuilt, this is the doctor''s shelter.


    The oxygen generator was removed from the car, and the "doctor" rushed to the medical box that he had already prepared.


    Chen Xin opened the medical box, checked the contents, then nodded to the "doctor", indicating that there was no problem.


    Seeing that Chen Xin had checked the goods and there was no problem, "doctor" immediately yelled at the clinic where he had changed his face. From there came an old man and a young girl carrying the oxygen generator in.


    Behind them, there is an elderly woman who is looking at them with alert face. At the same time, she is full of alert to Chen Xin.


    "Who are these?" Chen Xin frowned slightly. He once met a young girl, a little nurse working in the "doctor" clinic.


    A very simple little girl, but people are foreign, in the city after the health school to stay to work.


    As for the other two old men and women, Chen Xin has never seen them. Especially at this time, they both cover their faces with masks and scarves. They really can''t recognize who they are.


    "The doctor" heard Chen Xin''s inquiry and quickly introduced: "these are my parents. They used to live in the countryside. I didn''t want them to go to the official shelter, so I brought them to me."


    Chen Xin was not surprised to hear that the "doctor" said. This is also human nature. When he has the ability to have a place, of course, he has to consider his parents and family.


    If Chen Xin''s parents were not in his hometown in other provinces, he would let his parents live with him.


    However, Chen Xin is not worried about his parents. Before the disaster, he told his parents about the shelter and asked them to come back to live.


    However, Chen Xin''s parents think it''s too troublesome to run around. Moreover, the relatives in his hometown are from the same village, and the local people have built shelters in the village, so they don''t come back, but live with their relatives.So Chen Xin didn''t find it strange that "doctors" took over his parents.


    Just looking at the young girl who was carrying the oxygen generator with the father of "doctor", Chen Xin was a little curious about why she was here, and the look in her eyes at "doctor" became strange.


    It seems to be aware of Chen Xin''s eyes, "the doctor" suddenly felt embarrassed and quickly explained: "Xie Chang is alone in this city, and she can''t go back to her hometown after a disaster, so I left her to avoid going to the official refuge."


    "Is that so? So you''re going to be together? " Chen Xin looked at the "doctor" embarrassed appearance, immediately made fun of him.


    As a little nurse in the "doctor" clinic, it''s not strange for Xie Chang to say that there will be something between him and the "doctor". Especially in the current environment, the "doctor" has taken her in, and it''s not strange for them to be together.


    However, as soon as Chen Xin''s voice fell, his mother, who was looking at them, said in a very bad tone: "my son will not be with such a woman! Eat our family, live in our family, now still want to be my daughter-in-law? no way! She''s just a servant of our family


    "Doctor" mother''s words let Xie Chang move things can''t help but stiff.


    Chen Xin''s eyes suddenly changed when he looked at the "doctor" mother. Although this is reasonable, the attitude of the "doctor" mother is really uncomfortable.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 93

    "Mom, go ahead. It''s cold outside." The expression on the doctor''s face suddenly froze, and he quickly pushed his mother back into the room.


    After pushing his mother away, "doctor" said to Xie Chang, "Xiao Xie, my mother is such a person. She has no malice. Don''t take it to heart!"


    Obviously, the "doctor" did not regard Xie Changzhen as a servant who ate and lived in their house.


    In the face of other people''s housework, Chen Xin didn''t say anything. He just picked up the "doctor" to exchange his medicine box, explained to the "doctor" how to use the oxygen generator, took another look at Xie Chang, and then turned to drive his car away.


    On the way home, Chen Xin recalled his mother''s attitude towards Xie Chang, and felt inexplicably uncomfortable.


    Although the "doctor" mother''s attitude towards Xie Chang even before the end of the world seems to be a common norm, Chen Xin just thinks it''s wrong.


    Because it lacks the most basic respect between people.


    At the end of the day, maybe everyone is struggling to survive. Some people do selfish things in order to survive.


    But Chen Xin always thinks that even if he damages the interests and even lives of others in order to survive, he should maintain the most basic respect for others.


    The reason why people are called human is that we have human nature and morality, which is the biggest feature that distinguishes us from wild animals.


    If man can''t be called man, what''s the difference between man and beast?


    What''s more, even wild animals don''t make fun of bullying, maltreating and insulting the same kind.


    This is something that can only be done when people lose the moral bottom line and the most basic respect for people.


    Chen Xin has no intention to evaluate the "doctor" mother''s attitude towards Xie Chang, but he never hopes to meet such a person who does not know how to respect others.


    Fortunately, the doctor''s mother lives in their own shelter. Otherwise, if it''s an official shelter, her attitude towards people is likely to cause trouble.


    If put in the doomsday environment of those films and TV works, I''m afraid she is the fastest group of people to die.


    Chen Xin shakes his head. He seems to think that it''s not good to curse people to death. So he doesn''t think about it any more. He steps on the accelerator and plans to go home as soon as possible to see if the medical box given by the doctor can be upgraded into a medical room.


    It seems that the roads in the urban area have also been cleaned up. Although not all the roads are unblocked, at least several main roads remain unblocked.


    Chen Xin''s car didn''t drive slowly and soon returned to his refuge.


    After some cleaning up, Chen Xin returned to the living room with his medical kit. He found out his medical kit and first aid kit and put them together.


    Looking at his three pieces of medical supplies, Chen Xin thought about it and then moved a chair.


    If it is upgraded to a medical room, the upgrade level will not be too high. There is no need to make a medical bed, but at least there should be a place where you can sit down and deal with the injury or treatment.


    After getting everything ready, Chen Xin hesitated for a moment and put everything in the corner of the living room. Instead of moving to the empty garage, he planned to connect the medical room with the living room.


    Chen Xin plans to build a studio there to make some equipment or other things.


    After all, if we want to build big things like power armor or machine armor in the future, we must need space, although it is still far away for Chen Xin.


    Everything is ready, Chen Xin calls out the upgrade interface of the system.


    "Simple medical disposal room"


    "upgrade scheme 1: expand the space of medical disposal room, increase the operation seats, upgrade the surgical instruments, increase the sterile space, the bacterial reproduction rate is - 10%, and the survival point required for upgrade is 1000"


    "upgrade scheme 2: expand the space of medical disposal room, increase the detection equipment, increase the drug storage cabinet, and the drug storage time is + 10%, and the survival point required for upgrade is 1000"


    "upgrade scheme 2: expand the space of medical disposal room, increase the detection equipment, and increase the drug Survival 1100 "


    seeing the upgrade plan given by the system, Chen Xin finally felt relieved.


    He had been worried all the time. Even with the medical box given by the "doctor", the system still didn''t think it was enough to make up a medical room. What should he do.


    If that is the case, he will have to go to the "doctor" or get some medical supplies through Qin LAN.


    Although it''s not a lot of trouble, Chen Xin doesn''t like such a toss.


    Fortunately, the system has given Chen Xin a satisfactory result. He just needs to upgrade.


    Chen Xin is not in a hurry to upgrade. Upgrading the medical disposal room will require some materials if it is not just for survival.


    There are some things he doesn''t have. He plans to go back to Qin LAN to exchange.


    Anyway, now that he has the frequency of the communication channel of the special police team, he can contact Qin LAN by himself, and he doesn''t need to pass another message through Mo Qingyan.The result of being able to upgrade the medical room made Chen Xin feel in a good mood. It happened to be lunch time again. He decided to have something good today.


    From the storage room, he took out a can of pork and a shelter food from Qin LAN. After thinking about it, Chen Xin took out a box of luncheon meat and a cabbage.


    Since we have decided to eat better, it''s not a luxury to add one more dish.


    However, when leaving the storeroom, Chen Xin took a look at the beer and coke he had found from the outside, hesitated for a moment, and finally did not move.


    I''m afraid it will be a long time before the production of wine and drinks will resume in this end of life environment. Basically, what we can drink is the storage before the disaster. If we use a little, we can use less.


    It''s like the coke and beer Chen Xin found. Wheat is needed for brewing beer, but now it''s a luxury to brew beer with wheat.


    Coke may still be produced, but I''m afraid it will become something like a high-end luxury.


    So for the coke and beer that he found, Chen Xin won''t touch them easily before they expire.


    Unless it''s something that makes him happy enough, he''ll consider opening a can to celebrate.


    Open the can of pork, pour the stewed meat and congealed fat into the pot and heat it on the induction cooker. At this time, Chen Xin cleans up the cabbage, cuts it up with the lunch meat, and plans to fry it.


    When the gravy in the pot began to bubble, Chen Xin poured the meat and the juice back into the can.


    As for the remaining oil and a little juice in the pot, Chen Xin did not pour it out or wash it. Instead, he put it back on the induction cooker. Then he poured cabbage and lunch meat into the pot and stir fried them.


    At the end of the day, there is a shortage of materials. If you can save something like oil and salt, you can save it. After all, it''s hard for Qin LAN to get condiments like oil and salt.

 Chapter 94

    "Help others to improve their living conditions and get 100 survival points"


    "help 4 people to improve their living conditions and get 4 survival points every day"


    compared with Mo Qingyan who gave the oxygen generator to Mo Qingyan last time, Chen Xin received the survival point of "doctor" for two days.


    Of course, the reason is that he didn''t help Mo Qingyan with the door-to-door installation and provided a bottle of algae seedlings.


    Without the algae seedlings provided by Chen Xin, it will take some time for the "doctor" to get enough algae for the oxygen generator to work normally.


    However, since the survival has arrived, Chen Xin can naturally know that the oxygen generator of "doctor" has started to operate normally.


    In the past two days, Chen Xin was not idle. He used the materials at hand to make two more oxygen generators, but he didn''t go out to deliver them to the door.


    You know, a trip costs a lot of gas. In the past, it was just gas money. Now gasoline is an important material. Even if he has special police channels, the amount of gas he can change every month will be like his own consumption.


    It''s OK to go out once in a while and deliver it to people''s home, but he can''t even afford the generator.


    Before the biogas fuel cell is produced, Chen Xinke still relies on gasoline to generate electricity to support the operation of the whole refuge. If he can save gasoline, he can save it.


    Chen Xin himself does not go out, but others can come to him to get the goods.


    There is no unsalable trend in the two oxygen generators he made. Just as he said on the radio that he had made two more oxygen generators, someone decided immediately.


    Today, it happened that the survival of "doctor" had arrived, and the two oxygen generators were also taken.


    "Writer, I''m at your door. May I open the door?" Chen Xin was checking the growth of upland rice in the greenhouse. The radio station on his waist rang out a call.


    Chen Xin pulled the radio station from his waist and listened to the voice coming from it. He replied, "I know, Laonong. I''ll open the door for you."


    Seeing that people are already here, Chen Xin naturally can''t stay in the greenhouse. After a brief cleaning up, he plans to open the door.


    Of course, Chen Xin didn''t open the door foolishly. Instead, he went to the bedroom first, felt the pistol out of the weapon cabinet and put it on him.


    Even if he had a gun, Chen Xin didn''t open the door directly. Instead, he climbed from the passageway in the corridor to a small shelter with a short wave antenna, and took a look at the entrance of the shelter through the gap of the small shelter.


    Seeing that there was really only one car, and it didn''t look like there were other people in the car, Chen Xin climbed back down the passage and began to open the door.


    There were four doors in a row. After opening three doors, Chen Xin closed the innermost protective door connecting the shelter and the preparation room. Then he put on his gas mask, opened the remaining three doors and walked away.


    "The writer!" Seeing Chen Xin open the door and come out, the people in the car jumped down and said hello to Chen Xin.


    The person who came to get the oxygen generator is also a member of the survival group, nicknamed "old vegetable farmer", who is usually called old farmer.


    His real name is Li Wendong (provided by Shuyou No. 10 of Shuyou group). He used to operate hydroponic cultivation equipment in this city.


    When the disaster came, the group discussed how to prepare for the shelter. He also suggested planting greenhouses to ensure food output after the disaster.


    After the end of the day, we resumed communication. Chen Xin once heard him mention that he had built a fish vegetable symbiosis system in his refuge, which he envied a lot.


    We should know that this disaster can be called the catastrophe of the whole earth''s ecosystem. Not only the terrestrial life almost completely disappeared, but the marine and freshwater ecology also collapsed. The fish in Dongting Lake were caught on a large scale long before the disaster.


    On the one hand, this is to reserve more edible food, on the other hand, it is also to reduce losses.


    However, this batch of fish was not immediately used as food by the municipal government. Instead, it was canned and stored. It is regarded as the strategic reserve of the city.


    And this also led to the city now can not eat fish, even if Chen Xin can exchange materials from the special police team, there is no fish.


    But this is not a problem for Li Wendong.


    His fish and vegetable symbiosis system can provide him with fresh fish as well as vegetables as a normal greenhouse.


    This time, the price Li Wensheng paid for the oxygen generator from Chen Xin was ten fresh fish.


    In the last three or four months after the end of the world, Chen Xinzhen has never tasted any fresh meat, let alone fresh fish.


    He took the fresh-keeping box with fresh fish from Li Wensheng. Although he couldn''t smell it, he opened it and looked at the ten crucian carp in it. Chen Xin was still satisfied and laughed.


    He greets Li Wensheng into the shelter and takes out the oxygen generator from the garage of the servicing room and gives it to Li Wensheng.


    "Thank you so much, writer. Your oxygen generator is a real help in the snow!" After taking over the oxygen generator made by Chen Xin, Li Wensheng is busy thanking Chen Xin.Chen Xin looked at him strangely and asked, "old farmer, you have a fish vegetable symbiosis system in your family. Should the oxygen produced by the greenhouse be enough? You can''t use an oxygen generator! "


    "Writer, don''t mention the symbiosis of fish and vegetables. It''s hard to say!" Referring to his fish and vegetable symbiosis system, Li Wensheng had a helpless smile on his face: "the fish and vegetable symbiosis system is good, but it consumes electricity! You don''t know how much electricity the whole fish vegetable symbiosis system costs to run! "


    Hearing Li Wensheng''s complaint, Chen Xin couldn''t help picking his eyebrows and asked him, "Lao Nong, before you built this system, didn''t you consider its energy consumption?"


    "Of course I did!" The bitterness on Li Wensheng''s face was even worse, but he had to explain to Chen Xin: "at first, I thought it was not a big problem as long as there was no electricity in the urban area. As a result, because there was no official shelter in my home, the whole line was out of power.


    But it''s still within my expectation. I took this into consideration when I built the shelter, so I specially prepared three wind turbines. "


    "Wind turbines? They can''t cope with the current harsh environment, can they? " As soon as Chen Xin heard this, he knew exactly what kind of situation Li Wensheng had encountered.


    Speaking of this, Li Wensheng immediately complained: "yes, first acid rain penetrated into the bearing, resulting in power decline and serious wear of the bearing, and then low-temperature freezing rain directly froze the bearing All in all, the trouble is constant. All three wind turbines have been paralyzed in three months. "


    The resentment in Li Wensheng''s words made Chen Xin understand the dilemma he was facing at this time.

 Chapter 95

    Obviously, Li Wensheng originally intended to use wind turbines to power his refuge, so that all sufficient power can be used, but it is obvious that the harsh environment has greatly shortened the service life of the three wind turbines.


    Now it can''t be said that it is completely damaged, but the paralyzed wind turbine obviously can''t be repaired by Li Wensheng himself.


    So he had to rely on the generator as a backup power supply to power his shelter and maintain the operation of his fish and vegetable symbiosis system.


    This is obviously beyond the upper limit of Li Wensheng''s consumption, which makes him in a dilemma of energy shortage.


    "Then you won''t last long?" Chen Xin can''t help but worry about the current situation of Li Wensheng, especially when he just got the oxygen generator from Chen Xin. Although it doesn''t consume so much power, it needs to be on all the time.


    "Who said no? I''ve used more than half of the diesel I''ve stored. If I don''t replenish it, I won''t be able to sustain it for three months at most. " Li Wensheng couldn''t help shaking his head, his face full of sadness and helplessness: "I have now turned off half of the fish vegetable symbiosis system, and the harvested vegetables and fish have been temporarily processed and stored to reduce consumption. I hope I can last a few more months, or I can repair the wind turbine.


    If I can''t survive, I can only take my wife and children to the official shelter. I can''t watch them starve to death! "


    When Chen Xin heard Li Wensheng say this, he felt a little uncomfortable. He almost said that he could help Li Wensheng repair the wind turbine, but he still held back.


    Some things can help, and some things are better not to be so enthusiastic.


    Chen Xin, who resisted the help, thought about it for a while, but he still couldn''t bear to see the dying. So he said to Li Wensheng, "old farmer, if you have surplus output, try to exchange materials with the official shelter. Now I just exchange materials with the vegetables produced in the greenhouse and the official shelter, and I can barely keep on."


    Hearing Chen Xin say so, Li Wensheng''s face suddenly showed the light of hope, and quickly asked Chen Xin, "how did you change the writer? Can you change some resources for me? I don''t need anything else, just diesel! "


    However, Li Wensheng''s words have not been finished. Looking at Chen Xin and staring at him, he knows that he has said something wrong.


    Chen Xin didn''t say much to Li Wensheng, but just reminded him: "there should be a shortage of vegetables and fresh meat in the official shelters. Although they grow mushrooms by themselves and the city government has an underground planting area in the power plant, fresh vegetables and meat are still relatively scarce. Old farmers should be able to get the gasoline they need."


    "Well, thank you! I''ll go back first Li Wensheng left Chen Xin''s refuge with his oxygen generator because he was embarrassed by what he said just now.


    Chen Xin also closed the door of the shelter, carrying a box of fresh fish to the inside of the shelter.


    In fact, it''s not impossible for Chen Xin to help Li Wensheng change diesel oil. It''s just that he and Li Wensheng are not as familiar as Mo Qingyan, Ding Ning and Qin LAN. It''s OK to give him directions, but Chen Xin should come forward to help him change gasoline. Chen Xin thinks that he can''t be too enthusiastic.


    There are too many stories about Sheng mien fighting Mi Qiu in history. Although Chen Xin is not mean to help others, it does not mean that he will help others selflessly.


    In the final analysis, although Chen Xin exchanged materials with the SWAT team because the fresh vegetables on his hand were needed by the SWAT team, the main reason for reaching an equal deal was his relationship with Ding Ning and Qin LAN. Uncle Ding gave such a relatively generous exchange in the face of Ding Ning and Qin LAN.


    If Li Wensheng really can''t live any longer, Chen Xin may be able to help him change the diesel once or twice, but it''s impossible for Chen Xin to help him change the diesel for a long time to maintain the operation of his refuge.


    After all, Chen Xin has no reason to expend his human feelings to help others.


    However, the fish vegetable symbiosis system mentioned by Li Wensheng gives Chen Xin great inspiration and temptation. Maybe he can build a similar three-dimensional agricultural system.


    Try it the next time you upgrade the sanctuary?


    Chen Xin''s mind flashed this idea, can not help but began to seriously consider.


    While freezing the fish in the freezer, Chen Xin is thinking about the feasibility of this idea.


    Fish vegetable symbiosis system is a kind of circular compound farming system which combines fish culture and hydroponic cultivation. Its main principle is that ammonia nitrogen in fish manure is decomposed into nitrite by bacteria, and then decomposed into nitrate by nitrifying bacteria. Nitrate can be directly absorbed and utilized by plants as nutrition.


    After being absorbed by plants, the water is relatively clean and can be reused to provide fish, so as to realize fish culture without changing water and vegetable cultivation without fertilization.


    In this way, fish, vegetables and bacteria can form a complete cycle. Before the disaster of sunlight, the whole system can even feed fish with endless vegetables to achieve a closed-circuit cycle. Only 2-3 cubic meters of water and 20-30 square meters of vegetable cultivation area can basically meet the consumption needs of 3-5 people''s families.In the present eschatological environment, to maintain the operation of such a system, supplementary lights are needed to replace sunlight, and the planting area must be expanded to provide staple food output.


    Chen Xin''s current planting greenhouse does not have the conditions to do this. Although he once considered the symbiosis of fish and vegetables when building the shelter, the energy consumption of this set of equipment is far more than that of soil cultivation. Considering the energy consumption, Chen Xin gave up this idea and only built an ordinary planting greenhouse.


    But now that there is a system, Chen Xin thinks he can consider upgrading his greenhouse to a fish vegetable symbiotic system.


    However, energy consumption is indeed a problem that must be considered. After all, Chen Xin can only barely maintain the operation of the shelter at present, and the power supply depends on him changing gasoline from the special police force every month to maintain the operation of the generator.


    He doesn''t plan to increase the power burden of the shelter until he improves the power system.


    So the next step is not only to get the medical room out, but also to upgrade the power system.


    Although the power system was determined to be the top priority for upgrading from the beginning, but step by step, other things have been upgraded, but the power system has not been moved.


    Although the power system is still sufficient, Chen Xin decided to upgrade it. At least we should build up biogas fuel cells and reduce the load of generators.


    Of course, these things are not urgent. Right now


    Chen Xin looks at the fresh fish that has been put in the freezer and swallows his saliva. He hasn''t eaten fish for a long time.

 Chapter 96

    It''s not known whether Li Wensheng has changed to diesel. However, after he has built another oxygen generator, the materials he has on hand are exhausted. The remaining six friends who need the oxygen generator can only take the goods after he has obtained new materials from Qin LAN.


    Knowing this, the other six group friends can''t help themselves. In this case, waiting one more day will increase their chances of being in danger.


    But it is not easy to collect materials.


    Among the materials Chen Xin needs to make an oxygen generator, glass is the easiest to obtain. After all, if you don''t mind breaking glass, it''s really everywhere now.


    Pipeline, it''s easy to say, to have no one to live in the community demolition, how much can still be put together.


    It''s just that the vacuum pump and the fill light are not easy to collect. There are two friends in the fill light group who have their own spare parts, but no one really has the vacuum pump.


    So despite the urgency, in addition to the "doctor" who quickly got the oxygen generator, Li Wensheng and the other two group friends, the other six group friends still have to wait until next month.


    By sending out four oxygen generators and Mo Qingyan''s harvest, Chen Xin has earned a total of 600 survival points and an additional 16 daily survival points every day.


    Now Chen Xin has been able to harvest 18 + 16 survival points every day, and his monthly income has exceeded 1000 points.


    Compared with the time when Chen Xingang got the system, his monthly income was just over 300 points, which is really improving very fast.


    This also let Chen Xin understand the system to obtain the daily survival method.


    One of the natural ways is to improve the living conditions of his refuge.


    One is to help others and let more people improve their living conditions.


    They have their own advantages and disadvantages. It is not said that the latter is better than the former, but one may have a slower survival rate, and the other is faster, but there is a certain risk.


    After all, under the doomsday disaster, the darkness of the human heart breeds. Whether helping others is helping others or harming yourself needs to be well controlled.


    Therefore, it is more appropriate to help others appropriately, let oneself get more survival, and create a safer and more comfortable refuge for oneself on the premise of ensuring one''s own safety.


    Chen Xin, who is finally well-off in hand, doesn''t restrain his desire to upgrade and upgrades the kitchen.


    The kitchen is the place that Chen Xin considered upgrading at the beginning of acquiring the system. Originally, it was just the place where the induction cooker and kitchenware were placed. After Chen Xin upgraded, it was transformed into a formal stove, and there was a row of cupboards on the wall. It finally looked like that.


    However, the kitchen upgrade did not bring new daily survival for Chen Xin.


    This is not too hard to understand. After all, even if the kitchen is upgraded, Chen Xin still eats those things every day.


    Only if he can obtain more food materials and cook delicate and delicious dishes in the kitchen can he improve his living conditions.


    As for the medical room, because of the lack of some materials, Chen Xin can only wait for Qin LAN to send the materials and materials he wants this month before he can upgrade.


    Otherwise, he will have to spend 10 times of survival to upgrade.


    Although it is not impossible to say that, Chen Xin still insists on saving if he can.


    Besides upgrading the medical room, he also has to upgrade the power system, which is a big one.


    After all, the power system in Chen Xin''s plan also needs to be connected to biogas fuel cells, and if you want to have biogas, you must first build a biogas digester.


    Biogas digesters can''t be dug in situ. They can only be obtained by upgrading the algal oxygen generator. In addition, fuel cells must be kept as a survival.


    Qin Lan''s delivery time is quite punctual. Although we don''t care much about the time and date at the end of the day, Qin LAN still delivers Chen Xin''s materials on time at the beginning of each month.


    "Ah Xin, your gate is well repaired!" Qin LAN looked at the gate and entrance of the refuge which had become completely different from her last visit, and couldn''t help praising it.


    Hearing Qin LAN talk about this, Chen Xin can''t help but feel a sudden surprise. This is the first time that he has really exposed his upgraded system in front of others, which inevitably makes him nervous.


    So he asked Qin LAN casually: "do you think it''s good, Alain?"


    "Of course, it''s very good. Ah Xin, you can build it by yourself. It''s very powerful. Ordinary construction teams may not be able to do it like this." Qin LAN doesn''t seem to be aware of any violation. Instead, she praises Chen Xin''s craftsmanship: "I know you are skillful when I am with you. I didn''t expect that ah Xin has such ability."


    "I didn''t get a chance to show it before, did I?" Chen Xin can only smile right now.


    Through Qin Lan''s reaction, Chen Xin seems to understand what the system means by the fuzzy concept of information state.


    For example, the gate of this refuge, Qin LAN can see at a glance that this is not something Chen Xin can complete, but the concept of information state of the system is vague, which makes Qin LAN think that this is Chen Xin''s own construction and transformation.The concept of this information state is vague. It is difficult for Chen Xin to understand what level of technology it is, but it does not prevent him from understanding its effect.


    In short, it is to make everything reasonable and not to make people aware of the abnormality.


    Others will think that the upgrading of the refuge is Chen Xin''s own transformation. When new items appear, they will also think that Chen Xin made or bought them. In short, it is to make everything reasonable.


    Chen Xin doesn''t know if this is a halo of mental retardation. After all, this level is just rationalizing the appearance of various items, not mental retardation.


    Chen Xin didn''t think much about this problem and soon left it behind.


    Qin LAN will bring materials into the shelter, Chen Xin still asked her to sit down and drink water.


    Qin LAN didn''t refuse. She sat down on the sofa in the living room and looked around. Then she suddenly asked Chen Xin, who was pouring water for her, "ah Xin, don''t you have any heating equipment?"


    "Heating equipment? Yes, it should be enough to prepare an electric heater, sleep at night and an electric blanket. " When Chen Xin heard Qin LAN ask him about the heating equipment, he felt a little surprised, but he still replied, "I''m in the mountain. When I built the shelter, the wall was also insulated. The temperature is not too low. An electric heater is usually enough."


    "Your shelter is so big, there is only one electric heater, which can only warm one place. Is it cold in the room as a whole? And you still grow vegetables in the greenhouse. The temperature in the greenhouse can''t be too low! " Hearing Chen Xin say so, Qin LAN is still a little worried.

 Chapter 97

    Chen Xin doesn''t really care about Qin Lan''s worries. The system is in hand. He has the confidence to solve any problem. Even if he didn''t prepare enough, he can solve it by upgrading.


    It''s just like the problem of keeping warm in the greenhouse mentioned by Qin LAN. He can upgrade the greenhouse to one or two levels, so that it can have the function of heating and maintain a certain temperature by itself.


    Even according to Chen Xin''s plan, he wants to upgrade the shelter as a whole. The shelter can be upgraded with a heating system, just as he added a decontamination room and a servicing room when he upgraded the gate.


    In addition, the mountain itself has a certain heat preservation effect, so Chen Xin is not too worried about this.


    Just this words can''t just say with Qin LAN, so he nodded to Qin LAN and said thank you: "I know a LAN, thank you for your reminding, I will pay attention to this problem."


    "Ah Xin, you can only notice that there is heating equipment in the shelter of the Municipal Bureau. If not, I''ll go back and talk to the team leader and give you a more powerful one." Qin LAN takes the initiative to provide Chen Xin with a solution.


    Although they broke up, Qin LAN had no bad impression on Chen Xin. She still cared about him as before, but they were not so close, and they became just friends.


    Chen Xin actually feels the same about Qin LAN, but they are not suitable for each other.


    But maybe it''s a habit to care about Qin LAN before. Chen Xin still says to Qin LAN, "I don''t have a big problem here, but you should pay more attention to ah LAN yourself. You always carry out tasks outside. Now you are short of materials. You must wear more clothes when you carry out tasks outside without warm treasure."


    "I see. I will." Qin LAN smiles at Chen Xin.


    Looking at the familiar but long lost smile, Chen Xin said to Qin LAN: "stay for lunch and then go. I got some fish from my friends. I remember that you like to eat minced pepper fish head best, but I don''t have any pepper, otherwise I will make minced pepper fish head for you."


    Hearing Chen Xin say that there is fish to eat, Qin Lan''s face became obviously surprised: "ah Xin, can you even get fish? Now this thing is very scarce! It is said that there is fish culture in the underground planting area of the city government lane, but the yield is very low and there is no food at all.


    The fish caught before the disaster were also canned. The special police team got a batch of them, but the captain said that they were reserve materials and no one was allowed to move. "


    "In that case, ah LAN, you should stay for dinner." Chen Xinchong, Qin Lan said with a smile.


    In the face of Chen Xin''s invitation and the temptation of long lost fish, Qin LAN hesitates and chooses to stay.


    And Chen Xinjian Qin LAN agreed to stay for lunch, also took out his own reserves from the storage room, intended to treat her well.


    Although there are only canned pork, luncheon meat and mouse meat, plus his own cabbage, lettuce and carrots, the addition of a fish makes the lunch extremely luxurious and rare in today''s end of life environment.


    Find out sugar, vinegar and oil from the materials Qin LAN exchanged this time. Chen Xin plans to make a sweet and sour fish.


    Although all the fish Li Wendong brought are crucian carp, and crucian carp is not suitable for sweet and sour fish, Chen Xin still plans to make sweet and sour fish under the existing conditions.


    Because Chen Xin remembers that when Qin LAN cooked for him for the first time, he made his favorite sweet and sour carp.


    While thawing the frozen fish in the kitchen sink, Chen Xin puts all kinds of seasonings in the cupboard above the stove.


    "Alan, can the country still supply salt, sugar and soy sauce? It''s all out of production, isn''t it? " Chen Xin arranges these things while chatting with Qin LAN.


    "It''s OK. Although it''s scarce, it''s not enough to cut off the supply. There are sugarbeets and soybeans, even rice, planted by the municipal government in the underground planting area. There is no problem in making sugar, soy sauce and vinegar, but the yield is not high. " Hearing Chen Xin''s question, Qin LAN naturally answers his question.


    Some of the information Qin LAN heard when she was on a mission, while others were internal information she saw.


    The underground planting area built by the municipal government near the power plant does not only grow a single crop, but has a complete ecological agricultural system, which can produce a variety of crops, and can also carry out deep processing.


    Although the yield is not high, but the variety is very complete.


    Listening to Qin Lan''s answer, Chen Xin picked an eyebrow and asked curiously, "do they have pepper there?"


    "Of course! How can the people of Hunan not eat pepper! " Qin Lan''s face is natural.


    Qin Lan''s words made Chen Xin a little excited, and he quickly asked her, "can you get some pepper seeds for me? It would be better to have soybeans and beets, too. "


    "Oh, well, I''ll talk to the captain later. I think I can get it." Qin LAN nodded and agreed.


    If Chen Xin wants to grow crops, it may be a little difficult, but if Chen Xin only wants seeds, it is relatively not difficult to get them.


    Although the seeds of crops are very precious now, they are useless even if there is no land for cultivation. Therefore, the value of seeds is a little lower than that of crops in China.Of course, it''s still not something that everyone can get, but if the Swat wants to get some, it''s OK.


    Thinking of seeds, Chen Xin can''t help regretting the Doomsday Seed bag he bought before the disaster.


    At that time, considering the problem of planting after the disaster, Chen Xincai bought a complete variety of doomsday seed bags from the Internet to deal with the difficulty of getting food after the disaster.


    That seed bag contains 80 different kinds of seeds, from common vegetables such as cabbage and lettuce to watermelon and strawberry, even Cherry Radish, fruit cucumber, shallot and coriander.


    It can be said that as long as Chen Xin has this seed bag, he can not worry about food and drink. He can even build a small ecological park to meet all his food needs by using fish vegetable symbiosis and upland rice.


    Except for fish and vegetable symbiosis, Chen Xin didn''t think about it. That''s what he had planned. It''s a pity that he bought the seed bag through express delivery at that time. Even SF express, which has the most praise, can''t insist on delivering the express under the national martial law.


    So his seed bag was not delivered to him in the end, so it became an express that could never be received.


    After the disaster, he was able to grow only cabbage, lettuce and carrots, as well as upland rice.


    Fortunately, now Qin LAN says that she can help herself get the seeds, otherwise, Chen Xin can only consider asking other people who have extra seeds in their hands and find them to exchange some.

 Chapter 98

    After lunch at Chen Xin''s shelter, Qin LAN doesn''t stay long. She helps Chen Xin clean up and leaves.


    After Qin LAN left, Chen Xin directly looked at the medical supplies and chose to upgrade the medical disposal room.


    The green light still flashed by, but it didn''t build a room in place, but made a hole in the wall of the living room.


    The wall was decomposed by the green light, which extended to the mountain outside the wall. Soon a big enough hole was dug out in the mountain, and then a new room was built.


    When the green light dissipated, a small but fully functional medical room even capable of surgery appeared in front of Chen Xin''s eyes.


    With a little excitement, Chen xintui opened the door and went in.


    The medical disposal room is not big, just a long strip room. An operating chair is placed at the bottom of the room, and there is a curtain beside it, which seems to be able to be pulled up as a partition for the operation.


    In addition to the second half of the room, which can be used as a temporary operating room, the entrance of the room is a small table, on which are some things like testing instruments.


    Next to the table against the wall are two large cabinets, in which are some medicines and surgical instruments.


    There is no high-tech component in the whole medical treatment room, and it looks ordinary. Besides being able to do surgery, it can''t even compare with the school''s medical room.


    Chen Xin is very satisfied with this. No matter whether it is advanced or not, whether it is perfect or not, we should first solve the existing problems and then consider whether we want to make it better.


    After looking around the whole medical treatment room, he silently looked at all kinds of things, opened the cupboard and checked it. Even the operating chair was lying on it. After trying, Chen Xin felt that the medical treatment room was basically enough as it is now.


    After all, at this end of the day, the medical treatment room for ordinary minor injuries and minor diseases is fully adequate. As for the diseases or injuries that the medical treatment room can''t handle, Chen Xin doesn''t feel that he has enough ability to deal with them.


    In the final analysis, he is just an outdoor survival enthusiast who has learned first aid for a few days, not a professional doctor.


    When it comes to professional doctors, Chen Xin can''t help thinking about Mo Qingyan''s sister, who is a student of a famous medical college in Hunan Province and should have graduated this year.


    But last year, the school was delayed for more than half a year by various things, and her last year''s clinical practice turned into actual combat. Not to mention that she should have successfully graduated this year, she did not graduate because of the meteorite incident, and it is estimated that she will never get her diploma.


    Fortunately, this does not affect that Mo Qingxin has learned all the contents of the course. Originally, her last year was clinical practice. Compared with a formal doctor, what Mo Qingxin lacked was only experience.


    Thinking of this, Chen Xin can''t help thinking that if Mo Qingyan and Mo Qingxin can move to him, he can not only have two more people to work, but also have a doctor who is inexperienced but professional enough.


    However, this is just thinking about it. Not to mention how he persuaded Mo''s sisters to move to his shelter, even if they moved here and two women and a man lived in the same room, Chen Xin had no ability to refuse and resist, not to mention what he thought of Mo Qingyan and Mo Qingxin.


    Therefore, Chen Xin, who doesn''t want to be bothered by these problems, still doesn''t consider letting others move to the shelter for the time being.


    Of course, with the upgrading of shelters, recruitment is inevitable.


    After all, with the upgrading of the shelter, a lot of work needs to be done by hand. Sometimes, he alone can''t take care of it.


    It''s just that Chen Xin needs to think about it again. It''s a question of who to invite to his refuge and how to invite.


    Before clarifying his ideas and upgrading the refuge, Chen Xin doesn''t plan to think about it any more. At most, he can find out who he plans to invite.


    After all, even if the refuge upgrade is completed, according to the upgrade plan given by the system, it can accommodate only five people. Except Chen Xin himself, there are only four places left.


    After putting down the thinking about recruiting staff, Chen Xin turned his thinking back to the daily maintenance of the refuge.


    The current daily maintenance of the shelter is not easy. In addition to refueling the generator and daily cleaning, the maintenance of the planting greenhouse is Chen Xin''s most arduous work every day.


    When I came to the greenhouse, the vegetables on the hydroponic plate had been harvested, and now they were all empty, waiting for Chen Xin to plant again.


    The upland rice on the ground has already begun to be filled and harvested in another month.


    The carrots were replanted only last month. Now they are growing well. If Chen Xin wants to eat them, he can wash them and chew them raw.


    Although the tender carrot has not yet grown, the taste of this tender seedling is still good.


    However, Chen Xin did not do such a thing. Although he planted a lot of carrots in his field, his previous harvest had not been finished. There was no need to waste so much.


    After checking a cabbage and lettuce in the field, Chen Xin took down all the planting plates from the hydroponic plate and prepared for new breeding.It''s a troublesome job to keep seeds, because Chinese cabbage is a biennial plant. It takes about ten months to keep seeds. Even if the temperature in the greenhouse is constant and the growth cycle is relatively fast, it will take several months.


    However, the growth rate of lettuce is relatively fast. As the first batch of sown lettuce, the lettuce left by Chen Xin has already blossomed and seeded.


    It''s just that the seeds haven''t matured and can''t be harvested yet.


    Although lettuce can grow all the time if it only peels the outer leaves and leaves the heart, it also has a certain number of years. After one or two years, it will not grow. Therefore, Chen Xin still adopts the method of harvesting the whole plant and retaining the seeds.


    After cleaning the planting board, he took new seeds and put them into the planting board. After spraying water to keep them moist, Chen Xin put these planting boards back into the hydroponic tank.


    After a busy trip, he couldn''t help knocking his back, quite a bit sore.


    Although it is a person''s workload, it will be much easier if there is a person to help.


    Seeing that all the planting boards had been put back into the hydroponic tank, Chen Xin confirmed again that there was no problem, and then left the planting greenhouse.


    Although there is not much work to grow a greenhouse, Chen Xin came out of the greenhouse and looked at the time on his mobile phone, only to find that it''s time to have dinner.


    Of course, dinner is not as luxurious as lunch. Chen Xin just fried a lettuce and opened a portion of the shelter food Qin LAN sent today, which is regarded as dinner.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 99

    While eating dinner, Chen Xin is also planning his work for tomorrow.


    In fact, there are many things to do in the shelter every day, so Chen Xin has formed the habit of making a plan for himself to make things more organized.


    The greenhouse has already started breeding. It''s just necessary to check the germination of seeds these days. There''s no need to arrange the greenhouse work tomorrow. Just go and have a look in the morning, middle and evening.


    Qin LAN sent new materials and promised that the oxygen generators of the other six friends in the survival group need to be made as soon as possible. Chen Xin plans to make two of them tomorrow morning.


    Two oxygen generators are 200 survival points, and six are 600 survival points. Chen Xin can''t help paying attention to such a large amount of survival.


    However, Qin LAN has sent a lot of materials. Chen Xin has also reserved his share of making several more oxygen generators for his own use. He plans to make four more oxygen generators for himself this month, and then upgrade them with five oxygen generators as oxygen generating units, so as to improve the efficiency of oxygen generation and biomass generation of the oxygen generator as a whole.


    With enough biomass, Chen Xin''s biogas fuel cell can be put on the agenda.


    When the biogas fuel cell goes online, it can effectively reduce the load of the generator. When Chen Xin upgrades a new power generation method, the gasoline generator can be retired, and the gasoline can also be used for cars.


    In fact, in Chen Xin''s plan, the biogas fuel cell is only an electric assistant. The main significance of its existence is to consume the biomass produced by the algae oxygen generator, and release heat in the reaction process to supply the planting greenhouse.


    Chen Xin is not worried about the problem of low temperature heating mentioned by Qin LAN, but he still needs to consider it.


    After all, the level of the refuge is not high at present. Although the system upgrade can solve many problems, there are still many problems that can only be solved through the system upgrade after Chen Xin has found and thought of solutions.


    Thinking of these, Chen Xin is also thinking about how to upgrade the refuge for the first time.


    At present, as far as survival is concerned, as long as six oxygen generators are delivered to six group friends, he will be able to record another 600 points. Taking into account what he has saved before, according to the current rate of obtaining survival every month, Chen Xin estimates that in another month, he will be able to save enough survival for upgrading materials.


    As for materials, it is easy to say that the main ones are reinforced concrete, which can be provided by the special police force at present.


    Although there is a limit for Chen Xin to obtain materials from the special police force every month, just as there is a limit for the items sold in the store by limiting the players'' upgrade speed in the game, the total amount of materials Chen Xin needs is not large.


    Taking into account the materials that have been obtained from Qin LAN this month and the materials that can be exchanged next month, Chen Xin has calculated that they can almost meet the needs of upgrading.


    Chen Xin has been looking forward to upgrading the refuge as a whole since he got the system.


    After dinner, Chen Xin put everything away, turned on the TV and the game console, planned to play two games to relax himself, and took the wine out of the bedroom.


    However, while drinking and playing games, Chen Xin did not plan to play for a long time.


    He doesn''t play games very often. Although this is the only way of entertainment in the refuge at present, and it is also a channel for him to remember the years before the disaster, he doesn''t indulge in it. He still tries his best to restrain his desire to play games.


    On the one hand, game machines and TV sets are big consumers of electricity. It doesn''t matter when there was power supply in the past. It''s just a matter of how many words the meter left at the end of the month.


    But now it''s a matter of life and death. Chen Xin can''t waste too much power to play games. It''s better to supply the greenhouse with this power.


    On the other hand, Chen Xin doesn''t want to indulge in the game and cherish the past all day.


    This not only frustrates his own morale, but also has a bad effect on his mentality, which does not help him survive in this doomsday.


    Playing games properly can adjust the mood, relax the pressure brought about by the end of the day and relieve nervous tension, which is the same as playing games properly before the disaster.


    But if you indulge in games too much, it will bring all kinds of adverse effects just like before disaster.


    While rubbing the handle, Chen Xin suddenly thought that he had a game to play. What should the people in the shelter rely on for entertainment?


    Entertainment is necessary at any time. If only work is not relaxed, the negative emotions in one''s heart will grow rapidly, which will not only affect one''s mentality, but also lead to one''s character becoming more and more depressed, and even extreme thoughts.


    If only one person becomes like this, it''s OK. But if many people are like this, all kinds of social problems will follow.


    It''s like a string. If it''s stretched too close, it will break.


    Even the craftsmen in the ice age can enjoy drinking and boxing at minus 70 degrees to relax.


    However, after a little consideration, Chen Xin gave up thinking. It''s not that he can''t think of it, but that it''s too simple.Yanguo people have created too many ways of entertainment since ancient times. Before there was no TV in ancient times and now these dazzling electronic products, people''s entertainment life was also rich and colorful.


    Traditional opera may have been a bit old-fashioned, but the way of playing chess and cards is never out of date. Just a deck of playing cards is enough for a group of people to play all day.


    If you add mahjong, the quintessence of Yanguo''s traditional culture, it''s even more needless to say, playing eight laps first.


    Of course, these things are also the hotbeds for gambling, but Chen Xin does not think that the managers of the refuge will allow gambling to breed.


    And to be honest, Chen Xin didn''t think of anything to gamble on in the refuge under the doomsday.


    Although Yanguo''s government did not collapse and all departments were operating normally, it was obvious that money had become useless in the last days.


    So gambling? It''s better to bet on a few mushrooms.


    Maybe money can be used to buy things in the refuge, but when Qin LAN comes here to exchange goods, Chen Xin never mentions money. Chen Xin has a clear understanding of the purchasing power of money before the disaster.


    Moreover, under the doomsday, all the materials allocated to individuals are distributed according to their heads, which will be enough to meet the needs of survival. If someone is willing to pick something out of their teeth to gamble, Chen Xin can only wish him a good fortune as soon as possible and get rid of the doomsday.

 Chapter 100

    "Diddidi "Diddidi..." Set the time of the mobile phone on time, wake up the still sleeping Chen Xin.


    After grabbing the mobile phone and taking a look at the time above, Chen Xin puts the mobile phone back on the bedside table. After yawning, he rubs his face and sits up from the bed.


    He picked up the clothes at the head of the bed and just put a shirt on his body. Chen Xin suddenly felt a cool air passing from the clothes to him.


    Shivering with this coolness, Chen Xin quickly retracts the quilt.


    After wrapping himself in the quilt and warming his clothes with the help of the extra heat in the quilt, Chen Xin poked his head out of the quilt and thought about what happened today. It would be so cold.


    Now is not the past. If it is so cold in the morning before the disaster, it is estimated that we have encountered a cold current. It is not uncommon for us to cool down more than ten degrees a night in autumn and winter.


    In addition, the thermal insulation effect of ordinary houses in the south is the same thing. The outside temperature drops by more than ten degrees, and the inside temperature drops by at least three or five degrees or more without heating. It''s normal to get cold in the morning.


    But now it''s the end of the world, and Chen''s new residence is a shelter with good heat preservation effect, which should not be so cold.


    Is there something wrong with the heat preservation of the ventilation system? Chen Xin thought of this idea in his mind, but soon dismissed it.


    Although he feels cold now, it''s just because he doesn''t have many clothes on him. He just climbed out of the warm quilt and put on clothes with low temperature. In fact, the temperature is not so cold that people can''t accept it. At least he has a few degrees.


    If there is something wrong with the heat preservation of the ventilation pipe, which leads to the direct inflow of cold air from the outside, the temperature will be below zero at least.


    In that case, what Chen Xin feels is not cold but ice.


    And he only covered a camel hair quilt last night. Although the effect of warmth preservation is good, it is not so good that a quilt can resist the zero temperature.


    In the face of this strange situation, Chen Xin didn''t think about it any more. He quickly put on the clothes one by one and crawled out of the bed.


    After wearing the clothes, although Chen Xin still feels numb and cold because the temperature before the clothes is a little low, he can''t stand it.


    Especially after Chen Xin turned over all the sweaters and cotton trousers that he had put in the wardrobe, he didn''t feel cold.


    Previously, because of the shelter''s thermal insulation capacity, even if the outside temperature fell below zero, there were still more than ten degrees in the shelter. As long as he wore a thicker coat and had to work at ordinary times, Chen Xin didn''t think it would be cold.


    But today''s sudden drop in temperature caught him off guard.


    If it was before the disaster, Chen Xin might have felt his mobile phone to read the weather forecast before he got out of bed, but now he can only brush his teeth and wash his face to see the thermometer hanging on the wall of the living room.


    "Seven degrees? The temperature dropped six degrees in one night, isn''t it so terrible? " Chen Xin was surprised when he looked at the single digit temperature on the thermometer.


    I''m in the shelter. Not to mention the reinforced concrete walls around and the insulation measures inside, even the earth temperature brought by the earth mountain more than 200 meters above my head will not make the temperature of the shelter drop so much in one night!


    Chen Xin felt very strange, and even did not care to eat breakfast, so he left the living room and went to the public space, intending to check the ventilation system.


    However, looking at the ventilation system that still works well, and the cool air blowing from the ventilation system, Chen Xin can''t help touching his face. He already knows what''s going on.


    Chen Xin didn''t think much. It''s not the ventilation system or the heat preservation of the shelter. Unless he upgrades the ventilation system again or the shelter as a whole, this problem can''t be solved.


    Back in the bedroom, he turned out a temperature measuring gun. After checking that it could still be used, Chen Xinyou felt a large tool hammer from the workbench. Then he came to the servicing room and put on protective clothing. After putting on a protective mask, he took a flashlight and climbed to the small cover with communication antenna through the corridor.


    As soon as the door was opened, a cold wind came from the shop, which immediately made Chen Xin''s protective mask ice.


    Looking at the ice flower on the protective mask in front of him, Chen Xin reached out and touched it. When he saw that it couldn''t be wiped off, he stopped taking care of it. Anyway, it didn''t affect his sight.


    Turning on the flashlight, Chen Xin scanned the inside of a small shelter. As he expected, a layer of ice had formed near the vent, and the gap between the shelter and the outside world was covered with a thick layer of ice, which almost covered the whole gap.


    Carrying a hammer to the edge of the gap, Chen Xin raised his hand and knocked hard.


    Fortunately, the ice is not very thick. Although it is very strong, it can still be broken with a few knocks.


    As Chen Xin broke the ice that sealed the gap, more cold air poured in.


    Chen Xin raised his temperature measuring gun and pointed to the gap of the small bunker filled with cold air. The temperature displayed was - 34 ¡æ."No? Wasn''t there another one at minus four yesterday? 30 degrees in one night? " Chen Xin can''t believe it. It''s really terrible. It''s similar to the horror of the ice age in the movie the day after tomorrow.


    However, if the temperature drops by 30 degrees overnight, it will be similar to the effect shown in the day after tomorrow. After all, the ice age is 8-12 ¡æ lower than the normal temperature before the disaster, which is not so exaggerated.


    But Chen Xin can''t help worrying about another problem.


    Before the disaster, the climate of the blue star was already abnormal. At that time, scientists said that the blue star was going to enter a little ice age because of the destruction of the environment, the solar activity cycle entered the minimum period, and the heat shining on the blue star weakened.


    But this has always been just a statement. The little ice age that scientists want to talk about has never come, even though the time predicted by scientists is within 30 years.


    But now the situation of Bluestar is likely to enter the ice age directly, or it is already the ice age.


    If we enter the ice age, it is expected that the extremely cold night of a century will last longer.


    Human beings need a warm environment to survive. Although we expand our scope of activities to cold areas through construction, clothing, heating and other means, it does not mean that human beings can survive in the low temperature of tens of degrees below zero for a long time.


    Even for polar scientific research, it''s hard to be outdoors for a long time. Most of the time, they stay in the scientific research station.

 Chapter 101

    The sudden cooling makes the two problems of keeping warm and keeping warm become more and more serious.


    Although the external temperature is - 34 ¡æ and there is still 7 ¡æ inside the shelter, which is enough to prove that the shelter has excellent ability of keeping warm and resisting cold, it can not cover up the fact that the temperature inside the shelter is already very low.


    If the temperature is too low, it will affect the growth of crops.


    While thinking about these problems and cleaning up the ice in Xiaoyan''s body, Chen Xin had to think about how to improve the heating and warmth of the shelter.


    Compared with the problem of heating, keeping warm is not so difficult for Chen Xin. After all, his refuge is protected by more than 200 meters of soil layer. Even the entrance has a thick reinforced concrete and insulation layer. There is absolutely nothing to say about the thermal insulation performance. The indoor temperature of 7 degrees is the best proof.


    If you want to improve the insulation performance, Chen Xin thinks that he only needs to upgrade the insulation material of the wall again.


    as for the choice of upgrading insulation materials, Chen Xin has no idea what he wants, but if possible, he wants to change the insulation material of the wall into carbon aerogel.


    at room temperature and atmospheric pressure, the thermal conductivity of carbon aerogels can be as low as 0.013wm. K, which is the lowest thermal conductivity of LAN-STAR solid materials.


    Compared with the traditional polyurethane materials, the performance is more excellent, even in the extremely low temperature environment can still play a good insulation effect.


    But the heating problem is a little serious.


    Although the room temperature inside the shelter is still seven degrees, Chen Xin has no problem even if he doesn''t turn on the heater, but he can''t grow a greenhouse.


    Although low temperature will not cause crop death, it will reduce crop activity and slow down the growth rate. Crops that could be harvested in one month may take 40 days to harvest.


    Therefore, Chen Xin must find a way to maintain the temperature of the greenhouse at least 20 ¡æ to ensure the good growth of crops.


    undoubtedly requires a awesome heating system, which consumes a lot of electricity and petrol.


    After all, the calorific value of gasoline is here, and the energy that can be produced is fixed. When heat energy is converted into electric energy, there is a loss, and electric energy has to be converted into heat energy again. The energy loss in the middle is too high, and it is not worth the loss.


    After all, Chen Xin finds himself stuck in the energy problem. If this problem is not solved, it will be difficult for the shelter to continue to operate normally.


    After knocking on the broken ice in the small shelter and throwing it out of the crevice, Chen Xin hammered the tool back to the shelter.


    Taking off his protective clothing, he came to the planting greenhouse with a temperature measuring gun. He planned to measure the temperature of the greenhouse, and then he thought about heating.


    However, this measurement is somewhat beyond Chen Xin''s expectation. There is still a temperature of 11 ¡æ in the greenhouse.


    Chen Xin looked at the greenhouse in some surprise. He looked at the walls of the greenhouse and the lights hanging on the shelves.


    These fill light lamps are used to simulate the sunlight. The intensity can be equal to the natural light. Naturally, there will also be heat generation. In addition, the wall of the greenhouse is insulated. It is not difficult to understand that the temperature is higher than that of other places in the shelter.


    However, even so, Chen Xin still has to consider warming the greenhouse.


    Although the temperature of 11 ¡æ is not low, it will still affect the growth of crops.


    Put the temperature gun back in the bedroom cabinet, Chen Xin turned on the computer, eating self heating food as breakfast, while planning to check the information.


    Looking up the information, Chen Xin is also thinking about what kind of heating method is more suitable for him.


    Chen Xin''s refuge is located on the Bank of Dongting Lake. As the north gate of Hunan Province, the city has a large number of hot springs in both the South and the north. Unfortunately, there are no geothermal resources or hot springs in the city.


    If there are geothermal hot springs, Chen Xin feels that he can give up thinking and dig a large hot spring bath in the shelter. It is enough to use geothermal heat directly for heating. Even if geothermal heat is abundant, he can use it to generate electricity.


    However, Chen Xin no longer expects geothermal hot springs as a natural resource. Not to mention that there are no geothermal hot springs in the city itself. When Chen Xin upgraded the water supply system before, he drilled down 50 meters, and the extracted groundwater is not only not hot, but also a little cold.


    So Chen Xin doesn''t expect geothermal hot springs.


    While browsing the information, Chen Xin also noticed a piece of information that interested him.


    Although this information has nothing to do with heating, it still attracts his attention.


    This is a technology developed by an algae biofuel company in Florida. It uses the process of light synthesis in blue-green microalgae cells to produce ethanol.


    The ethanol produced by blue-green microalgae can be excreted through the cell wall, collected as a dilute ethanol solution from a closed photobioreactor, and purified into fuel grade ethanol.


    This is a new technology that was still in the experimental stage before the disaster, but the prospect is really promising, and the technology itself has been proved feasible.According to the company''s data, they expect to build 430 hectares of bioreactors, which can produce about 56000 hectares of ethanol a year. On average, one bioreactor can produce about 130 liters of ethanol.


    A photobioreactor has about 4500 liters of culture medium, which is 4.5 cubic meters by volume. Chen Xin thinks that he can consider upgrading his algae oxygen generator to this mode, producing ethanol while producing oxygen.


    You know, ethanol is a very good fuel. Although 130 liters is not a lot, it can be used in many ways.


    After recording this information, Chen Xin searched again, and then found the information he wanted to find, the shallow geothermal energy utilization project planned by Yanguo in the 13th five year plan.


    The so-called shallow geothermal energy refers to the geothermal resources contained in the surface 0-200m depth, which is a concept of energy relative to geothermal resources.


    Although it belongs to geothermal energy as well as geothermal resources, the definition of shallow geothermal energy is < 25 ¡æ shallow low temperature geothermal energy, and its main utilization mode is heating before disaster.


    Although the utilization technology of shallow geothermal energy is not a new technology, because the three shallow geothermal energy utilization projects in the city were only planned in recent years, they were not completely completed, let alone put into use, until the disaster.


    Looking at the introduction and related information about geothermal energy, Chen Xin couldn''t help feeling excited. Do you want to do this? If it is successful, it will not only solve the current heating problem, but also develop deeper geothermal resources in the future.

 Chapter 102

    Shallow geothermal energy is different from deep geothermal energy. Although both belong to geothermal energy, the utilization of shallow geothermal energy is much simpler than deep geothermal energy.


    The utilization of deep geothermal energy needs deep drilling, which is difficult to exploit and relatively difficult to use effectively.


    However, the utilization of shallow geothermal energy is not so complicated. It only needs to embed pipes in the shallow surface, inject circulating working fluid into the pipes, connect the heat pump units, and promote the circulating working fluid to continuously realize the process of absorbing geothermal energy and releasing heat energy, so that the shallow geothermal energy can be effectively utilized.


    In fact, its principle is the same as that of air conditioner and refrigerator. It uses circulating working medium to absorb heat, then compresses and condenses to release heat.


    But different from the public regulation and refrigerator, the ground source heat pump using shallow geothermal energy absorbs heat from the ground and releases heat indoors.


    In fact, this system can be used not only for heating, but also for refrigeration, which is totally useless in the current environment.


    Compared with other heating methods, the advantage of ground source heat pump technology is that it consumes less energy. Although it also consumes electricity, it only needs to supply the electric energy required by the compressor, and does not need to consume additional electric energy to heat.


    After all, whether it''s boiler burning or electric heating, in essence, it''s energy consumption to convert heat. Even air conditioning heating is also electric auxiliary heating, which needs to consume a lot of electric energy.


    But the ground source heat pump technology is different, its heat comes from the ground itself, the ground source heat pump unit is only used to compress and condense the circulating working medium, and release heat, there is no additional energy consumption.


    So relatively speaking, the ground source heat pump really needs to save a lot of energy.


    Looking at the introduction of the materials and the explanation of the relevant principles, Chen Xin came up with the idea of applying such a system to his refuge.


    On the whole, it''s not complicated to make such a set of things. All he needs is pipes, compressors, condensers, evaporators and expansion valves, which can be obtained by dismantling an air conditioner.


    And the installation is not troublesome. Since a simple shelf can be regarded as an algae oxygen generator by default, it should also be regarded as a ground source heat pump system if the pipe is buried in the soil of the planting greenhouse, and then other equipment is installed to dissipate heat to the planting greenhouse?


    Although this still aggravates Chen Xin''s power consumption and makes his already overburdened power system worse, as a necessary consumption for heating, Chen Xin can only accept this fact and chooses to upgrade the generator to increase the total power generation while increasing the fuel consumption.


    "Simple fossil fuel internal combustion generator"


    "upgrade scheme 1: improve the working efficiency of the generator, fuel efficiency + 5%, improve the motor material, power generation + 5%, energy consumption - 5%, upgrade survival 1700"


    "upgrade scheme 2: improve the output power of the generator, fuel consumption + 75%, power generation + 90%, energy consumption - 5%, upgrade survival 2" 000 "


    this is already a very high survival consumption upgrade. In addition to the overall upgrade of a room, Chen Xin upgraded a single device with more than 1000 points for the first time.


    Fortunately, in addition to Chen Xin''s spare generator, the required materials are all kinds of metal materials. Chen Xin provided a large number of steel as a substitute, but he still completed the upgrade with one tenth of the survival cost.


    After upgrading, the generators become bigger, and two of them become one. In addition to the increase of fuel consumption, the power generation is also greatly improved.


    However, in general, the energy consumption has been reduced, because Chen Xin can now use 1.75 times of the original fuel to obtain 1.9 times of the electric energy. In general, the consumption has been reduced.


    Moreover, after the upgrade, the power generation efficiency is improved, and the total power consumption remains unchanged, which means that the fuel consumption is reduced by changing the direction.


    Taking Chen Xin''s current fuel consumption as an example, his inventory and the gasoline he can exchange from the special police force every month can meet his own consumption.


    Of course, this does not include the upcoming increase in heating consumption.


    For heating, Chen Xin is also in a dilemma. Electric heating is the most efficient way, but it is the most simple and fast way. Chen Xin only needs to plug in his electric heater.


    As for the boiler is not bad, boiler water heating this is an old and mature technology, relatively more safe and stable, the carbon dioxide produced by combustion can also be supplied to the oxygen generator for oxygen recovery, can be said to be a very good choice.


    The only restriction for Chen Xin to adopt this heating method is the acquisition of fuel.


    To get warm in this way, Chen Xin may have to add coal to his monthly deal with the Swat.


    In exchange for coal is not a problem for Chen Xin. After all, coal is not gasoline, and Yanguo''s coal production is also quite high.


    Only in this way, the painting style of Chen Xin''s refuge will inevitably be close to the style of Steampunk.


    Although he personally likes the art of Steampunk style, it doesn''t mean he wants to live in such an environment, because Steampunk also means soot pollution.Of course, no one is going to investigate whether your PM2.5 exceeds the standard in this last world environment. The PM2.5 of the whole atmosphere has already exploded.


    So of course we can do it, but how to do it is a big problem.


    When Chen Xin was a child, he saw that kind of honeycomb coal stove in his hometown. Even now, this kind of thing is still widely used in the countryside of Yanguo.


    If it is to use honeycomb briquette for heating, Chen Xin thinks it should be an acceptable and effective choice.


    In addition, the ground source heat pump system with shallow geothermal energy is also a very good heating method, and even this system will not increase additional energy consumption. For Chen Xin, who has problems in energy acquisition, it is simply the most suitable heating method.


    In fact, the ground source heat pump technology has been used in Bluestar for a long time. It was first proposed in 1912, but at that time, the energy was relatively cheap. In addition, limited by science and technology at that time, there was no large-scale application.


    But after entering the new century, the energy problem of mankind is increasingly tense. Clean, efficient and recyclable new energy has gradually become the focus of people''s attention. The development and utilization of shallow geothermal energy by ground source heat pump technology has naturally been greatly developed and widely applied.


    In Yanguo''s Qinghai Tibet Plateau, this technology has been applied to the heating of local people, but the technology is not very mature. Although it has been applied, it is still limited to simple heating.


    However, the advantage of this technology is that its heating efficiency is quite high.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 103

    According to the law of conservation of energy, it is impossible to use 1kW ¡¤ h electricity to generate heat more than 1kW ¡¤ h, but if the ground source heat pump technology is used, 1kW ¡¤ h electricity can bring 4kw ¡¤ h heat or cooling.


    At first glance, it seems very magical, a bit like civil science cheating people, but in fact, it is a real technology, and things that can achieve this efficiency can be found everywhere in our lives, the most representative of which is air conditioning.


    In thermodynamics, the ratio of energy conversion efficiency is called cop.


    Among them, the energy efficiency ratio of electric heater, that is, direct electric heating, is the lowest, only about 60%, that is, it consumes 1kW ¡¤ h of electric energy and can produce 0.6kw ¡¤ h of heat.


    In addition to electric heating, the energy efficiency ratio of energy boilers is also different according to different fuels. The energy efficiency ratio of natural gas and oil fired boilers can reach 0.9, while that of coal-fired boilers is only 0.6.


    On the contrary, the energy efficiency ratio of the electric boiler is quite high, which can reach 0.95, that is, the so-called direct use of electric oven is not as good as using fast heating to boil water.


    It''s very efficient to achieve an energy efficiency ratio of 0.9. After all, the law of conservation of energy is stuck here and can''t reach 1 in any case.


    But when the air conditioner is cooling, the energy efficiency ratio can reach more than 3.


    This does not violate the law of conservation of energy, because the air conditioner uses refrigerant to carry the indoor heat to the outdoor, the heat driven by it is not generated by it, but exists in itself, and the air conditioner only carries it.


    In fact, in China, air conditioners with an energy efficiency ratio of less than 2.6 ~ 2.8 are not allowed to be sold at all, and only those with an energy efficiency ratio of more than 3.2 can be called air conditioners in the true sense.


    And understand this point, ground source heat pump can achieve 4 energy efficiency ratio is not uncommon.


    As for why air conditioning and ground source heat pump can achieve such energy efficiency ratio, it is because they all have a series of equipment including compressor, evaporator, condenser and expansion valve, which is much more complex than boiler and other equipment.


    But just because of a set of complex equipment, it also brings considerable energy.


    Using 1kW ¡¤ h electricity to bring 4kw ¡¤ h heat is obviously input > output.


    Looking at the data, Chen Xin has an idea in his mind. He finds a piece of paper and a pencil and plans to think about it.


    "Using 1kW ¡¤ h of electricity to bring 4kw ¡¤ h of heat, even if only half of the heat is used for heating, it''s more profitable than directly using the electric heater or electric boiler..." Chen Xin scribbles on the paper. He doesn''t want to draw anything. It''s just a tool for thinking: "if half of the heat is used for heating, the remaining half is used for power generation..."


    It doesn''t matter what is painted on the paper. What is important is what Chen Xin is thinking about. With his thinking, there is a ray of light in his mind!


    "No matter how low the efficiency is, as long as there is an energy efficiency ratio of 0.6, the system can run on its own!" Chen Xin slapped the table hard, and the whole person was excited.


    This is not a bullshit perpetual motion machine. It''s just a common waste heat recovery power generation in industry. Of course, Chen Xin''s waste heat recovery is a little too much, enough to make this set of equipment self-sustaining.


    It is not difficult to achieve this, because after the refrigerant brings heat from the stratum, it needs to evaporate and release a lot of heat. In this process, whether Chen Xin is preparing to boil water or thermoelectric power generation, it can generate enough power to maintain the operation of the whole system, and there is enough heat for heating.


    As for the need to drill holes in the ground to realize this system, Chen Xin lives in an underground refuge. Above his head is a soil layer more than 200 meters thick, which can be about 200 meters underground.


    This can be seen from the fact that Chen Xin''s shelter can still have a temperature of 7 ¡æ when the external temperature is - 34 ¡æ. If the ventilation system is not constantly ventilating, causing a certain loss of heat energy, the temperature of the shelter can actually be a little higher.


    So if Chen Xin wants to use the ground temperature, he doesn''t need too much trouble. He just needs to bury the pipes in the ground, or even directly into the soil of his greenhouse.


    Although it is possible to reduce the soil temperature of greenhouse and affect the growth of crops.


    But Chen Xin can just build the system in the soil layer where the greenhouse is planted, and then use the system upgrade to re plan, burying the pipeline into a deeper layer.


    In fact, Chen Xin''s entire refuge is wrapped in thick reinforced concrete and thermal insulation layer. If Chen Xin wants to bury the pipeline in the real stratum, he needs to pierce through at least 40 cm thick reinforced concrete.


    Without the help of the system, Chen Xin would give up the idea.


    After having the system, all Chen Xin needs to do is upgrade it with the system.


    Up to now, Chen Xin has thoroughly understood the horror of this system. Although there is only one simple upgrade function, and there are not so many different patterns and exchange functions of other systems, it is such a simple function. If you use it well, you can play with it.It''s true that the system can''t change things out of thin air, it must have basic items as the basis, but in fact, the upgrade of the system is still very terrible.


    Chen Xin is a novelist, and novelists are monsters with black holes above their necks. In addition, he likes to think, so Chen Xin has tried to analyze the principle of system upgrading.


    However, the conclusion is that the upgrade of the system is far from what he imagined. He stored high technology and then upgraded and unlocked it step by step.


    It''s a more terrifying concept upgrade.


    For the simplest example, if the system is upgraded by science and technology, then if Chen Xin has a tree stick, he can choose to process it into spears, sticks, swords or bows and arrows. In the subsequent upgrade, he can add new materials to replace it and make it more advanced.


    All these should have context and rules to follow. After all, the development of every science and technology must have its own pre science and technology.


    However, although the upgrading of the system seems to be the same, it is actually much more terrifying, because according to the function of fuzzy concept of information state attached to the system, Chen Xin analyzes that the so-called upgrading of the system is to make an object more powerful in the sense of concept and information.


    Since this higher civilization can modify the information contained in an article to make people think it is reasonable, it can also modify the information contained in an article to make it more conceptual. Chen Xin''s choice of upgrading scheme is the process of giving concepts.

 Chapter 104

    Chen Xin doesn''t know how powerful the function of the system can be. The result of his analysis is just the product of the black hole above the neck of the Internet writer.


    But this does not prevent Chen Xin from using the system, and he knows how to use it to make the system achieve his expected idea.


    "But before that, let''s get down to business." Chen Xin took a deep breath, closed his laptop, cleaned up the leftover breakfast, and then came to the radio station.


    Last night''s sudden cooling had a great impact on people like him who have solid and reliable shelters. It''s hard to imagine what those shelters in the city will be like.


    In particular, Chen Xinke, a few friends in the urban area, still owes others six oxygen generators! Chen Xin doesn''t want them to go to the streets like this before they have collected the 600 point survival.


    "Call, call, this is the writer. The temperature dropped suddenly last night. Are you all right?" Turn on the radio, although it''s not the fixed communication time agreed by everyone, Chen Xin still makes a call.


    "This is an old vegetable farmer. Last night, there was a sudden snowstorm in the urban area, and the temperature dropped by 30 degrees. Now it''s only - 35 ¡æ. I was directly awakened by freezing last night. Half of the vegetables in the greenhouse were frosted, and the losses were heavy!" The first person to respond to Chen Xin is Li Wensheng. His voice is full of heartache. It is obvious that the cooling last night made him lose a lot.


    Through Li Wensheng''s words, Chen Xin understands what happened last night, and has a clear understanding of the impact of the snowstorm that suddenly fell last night.


    Chen Xin''s shelter is well blocked by the mountain. Li Wensheng''s shelter is built directly under his villa. In terms of heat preservation and heat insulation performance, it is far from perfect.


    From Li Wensheng''s words, Chen Xin can know that the temperature of his shelter has at least dropped below zero, otherwise the vegetables in his greenhouse will not be frosted.


    Thinking of this, Chen Xin can''t help feeling a little worried about them.


    Although private shelters are built underground like official shelters, and people with a little money can do the same heat insulation measures as official shelters built by the state, it will undoubtedly increase the cost greatly.


    Like Chen Xin''s shelter, he made a polyurethane insulation layer in the wall, which also accounted for a large part of the cost of building the shelter.


    , but this is not enough money for everyone. For example, "doctor" home, Chen Xin knew that he did not make polyurethane insulation because of funding problems, but instead of foam plastics.


    Li Wensheng is a little better than "doctor". He uses ultra-fine glass wool, while Mo Qingyan uses the same polyurethane as Chen Xin.


    foam and superfine glass wool are both thermal insulation materials used in cockpit and cockpit. The performance of foam plastics is not bad, but it is much worse than that of ultra-fine glass cotton, let alone comparing with polyurethane.


    as for other friends'' shelters, they also have thermal insulation materials, but most of them are foam plastics similar to that of doctors.


    Although this relatively cheap material has average performance as thermal insulation material, its price is very affordable. It is a good choice for people who do not have much money to build private shelters.


    just had to face a question mark in the face of the thirty degree blizzard that cooled overnight.


    Fortunately, with Li Wensheng''s voice, other people also answered after hearing the call. After all, the blizzard brought about a 30 degree overnight cooling, which seriously affected everyone. It is possible to get help by contacting other people in time at this time.


    Listening to everyone''s report one by one, Chen Xin can''t help feeling a little heavy.


    Apart from him and Mo Qingyan, two of the ten shelters built by the group of friends in the urban area couldn''t hold up and chose to send a message for help to the official shelters.


    Chen Xin knows that the shelters of the two friends who gave up were changed into small garages. Although they are still well equipped, well prepared and have a lot of materials in reserve, it is obvious that their shelters are still lack of enough resistance in the face of this degree of cold.


    If it''s not that we can''t make it, who can''t keep the comfortable private shelters and squeeze the official ones?


    The abandonment of the two friends made everyone feel a little heavy, and Chen Xin wanted to do something for them.


    Even though Chen Xin has a system to help them, the two friends who choose to give up are already unable to withstand the cold. They can only light a campfire in the shelter with the reserved fuel and wait for the official rescue. They can''t last long.


    Unless Chen Xin can build heating equipment in the shortest time or provide them with better thermal insulation measures, what is waiting for them is freezing to death.


    But the blizzard outside has not stopped. In this weather, even if Chen Xin wants to save people, he has no ability to save people. In this weather, Chen Xin can''t drive out in the blizzard.


    However, Chen Xin said on the communication channel: "ladies and gentlemen, I can make ground source heat pump devices that use ground temperature for heating. It''s just that compressor, evaporator, condenser and expansion valve are needed to make this kind of equipment.In short, you can think of it as an air conditioner. The materials needed to make the equipment are available on the air conditioner. As long as you can bring me these parts, I will be able to make ground source heat pump devices for you. "


    "Ingredients are you kidding? Can you really build a ground source heat pump Mo Qingyan doubts Chen Xin. She is too familiar with Chen Xin. She has never heard of Chen Xin''s talent.


    And since Chen Xin has such ability, why didn''t he say that he could manufacture ground source heat pump before the disaster?


    At that time, whether they were collecting materials or installing equipment, they had far more resources to use and more convenient.


    "I can make it, but it takes a lot of materials to make one." Hearing Mo Qingyan''s query, Chen Xin naturally understood that his behavior was suspicious, but he explained: "I''ve been reading books on machinery manufacturing these days, and I''ve accumulated some experience. It''s no problem to make such a device, as long as you can provide materials."


    Manufacturing equipment may not be a problem, but it''s obviously not the end of the matter to make the equipment.


    Although Mo Qingyan believes that Chen Xin can indeed manufacture ground source heat pump devices as heating equipment, she still asks Chen Xin, "but ah Xin, you said that the ground source heat pump pipes should be buried underground, right? Even if you don''t need to hit hundreds of meters deep, you still need dozens of meters? Now the temperature is more than 30 degrees below zero, and the ground has already frozen hard. What can we do to open holes on the ground? "

 Chapter 105

    In the face of Mo Qingyan''s question, Chen Xingang is ready to say that he can have a drill to help them drill holes, but he can''t help but stop.


    Of course, he can take out the right bit. He just needs to upgrade the hand drill on the tool table, not to mention just making a hole tens of meters deep in the frozen soil. Even if he wants to drill deep, Chen Xin can also bring out drilling equipment through system upgrading.


    But is it really good for him to do so?


    Chen Xin couldn''t help shaking his head.


    These friends have indeed encountered difficulties, but they are far from being able to survive.


    At this time, they still have shelter to live in and supplies to support their lives. Although the temperature is really a little low, this issue was raised and discussed before the end of the day, and everyone has made full preparations.


    So, even though their shelters are really cold now, they are not so livable that they can still maintain enough temperature with heating equipment.


    It''s just that doing so will consume a lot of reserved fuel or increase energy consumption, shorten their theoretical survival time, and will not really make them unable to live.


    And even if we really can''t survive, just like those two friends who asked for help from the government, sending out a distress signal and moving to the official shelter is also the way to survive.


    Chen Xin''s help to them is only to help them continue to survive in the form of private shelters, not to help them tide over the survival crisis and save their lives.


    Since it did not endanger their lives, there was no need for Chen Xin to rush to help them by consuming a lot of survival.


    The system can really help him rationalize various items or equipment, but it''s only limited to the items themselves, so that people don''t think that a certain item is too black technology, instead of making people become idiots and turn a blind eye to the things Chen Xin brings out and the behaviors he makes.


    It''s normal for others to process or exchange some materials. After all, everyone needs something or lacks something at the end of the day.


    But I''m in a hurry to help others Although it''s true that doomsday survival is about unity and cooperation, it''s not the right gesture to help others in such a hurry.


    If they have run out of ammunition and food at this time, they will not survive without any help. Chen Xin will help them to survive anyway, but it is far from the last moment.


    -The low temperature of 34 ¡æ is indeed dangerous and fatal, but it is not impossible for human beings to survive in such an environment.


    The former leader of the union of sovia, father steel of Georgia, was once exiled to kuleika, a small village close to the Arctic Circle, which can not be found on the map. He spent a long five years in the cold winter of minus 60 degrees in Siberia. He lived in a simple wooden house and lived a primitive life like a wild hunter, living only by hunting and fishing.


    But even in such a bad environment, the steel father also tenaciously survived, and exercised his will like steel.


    Chen Xin nibbles his finger and thinks silently that helping group friends can help him gain survival, which is the biggest benefit for him. Moreover, he can take this opportunity to exchange a lot of resources he needs from group friends, although these group friends may not have what he wants.


    But it''s also easy to expose some problems, such as where Chen Xin''s equipment came from, and what''s his motivation to help people


    The darkness of people''s heart is deeper than we think. Chen Xin must consider what kind of consequences he will bring if he shows too warm kindness.


    Finally, he made a decision, so he pressed and held down the talk button on the radio station again and said in a cold voice: "I can get drill bits, provide ground source heat pump equipment, and even help you install them, but everything is not free. I need you to exchange materials."


    With that, Chen Xin quickly released the speaking key, took a long breath, relieved his nervous mood, and then waited for other people''s response.


    This is Chen Xin''s response. He puts forward an attitude of "help is OK, you need more money". It can help others to collect survival, and also avoid being thought that people are stupid and have more money, so they should not have some ideas.


    Coupled with a little military deterrence, Chen Xin thinks that this should be able to protect his own security.


    "Ah Xin, can you really get a drill? You don''t want to find a LAN... " Mo Qingyan takes the lead in speaking, but she turns her thinking to another direction and adds some plot to her mind.


    For Mo Qingyan''s guess and brain supplement, Chen Xin naturally understands her meaning as soon as she hears it, but this is what he wants to see.


    So Chen Xinshun continued with her words: "well, I''m going to ask the SWAT team to get a drill through a LAN. After all, even if I don''t install it for you, I will install such a set of equipment to keep warm. So I definitely want to get a drill, but I use it myself and help you with it."


    Chen Xin''s reply makes Mo Qingyan silent. He doesn''t know what Mo Qingyan wants to express, but other people don''t care about the strange atmosphere between them. Instead, they ask Chen Xin about the heating effect of ground source heat pump equipment and the installation conditions.And the most important thing is what kind of exchange terms Chen Xin needs to agree to help others make and install such a device.


    For the heating effect and installation conditions of ground source heat pump, as well as the maintenance and consumption after installation, Chen Xin has made a detailed explanation.


    However, when everyone asked about the cost, Mo Qingyan suddenly stepped in, interrupted everyone''s speech, and announced in a loud voice: "ingredients, give me the first set, I''ll give you ten cases of wine, ten cases of luncheon meat, five cases of pork And my sister! "


    "Mo Qingyan, what do you want?" Hearing the exchange offer offered by Mo Qingyan, Chen Xin was shocked and recovered for a long time.


    However, Mo Qingyan didn''t want to explain to him. She just stressed in a very tough tone on the radio: "I feel cold, so I want to be the first to install heating! Who has an opinion? Take out more things than me. I''ll let you pretend first


    Mo Qingyan''s attitude makes others do nothing but acquiesce to the fact that Chen Xinxian has installed ground source heat pump equipment for her.


    This also creates a very strange situation, that is, if other people want to install the ground source heat pump, the materials they exchange can''t be much lower than what Mo Qingyan brings out, but such a large amount of materials are difficult or reluctant to bring out.

 Chapter 106

    "So long Niang, do you want to block other people from exchanging ground source heat pump equipment with me in this way?" Sitting on the sofa in the living room of Mo Qingyan''s refuge, looking at Mo Qingyan sitting in front of her and Mo Qingxin standing behind her, Chen Xin can''t laugh or cry.


    Because Mo Qingyan''s speech before made it difficult for Chen Xin and other friends to ride the tiger, so after waiting for three days and the snowstorm abated, Chen Xin drove to Mo Qingyan and asked her about the motivation for doing so.


    However, the answer given by Mo Qingyan makes Chen Xin not know whether to thank her or blame her.


    In the face of Chen Xin''s inquiry, Mo Qingyan nodded her head very seriously and seriously, and criticized Chen Xin in a very angry tone: "you are so kind-hearted! How can you freely show that you have such ability in this kind of doomsday? What if someone has a bad heart for you? "


    "No, no!" Chen Xin smiles, but is very grateful to Mo Qingyan.


    Although Mo Qingyan doesn''t know his plan, and even his plan of harvesting survival has been affected by this, Chen Xin is very grateful for Mo Qingyan''s willingness to help him in this way.


    Although Mo Qingyan and he are very good friends and even good brothers, it doesn''t mean that Mo Qingyan needs to help Chen Xin so much. After all, it''s the end of the world. Everyone has to plan for their own survival. No one will really help others selflessly regardless of gains and losses, because that will only make him unable to live.


    Mo Qingyan was able to help him in this way, although she only said something to help him. She didn''t really have to pay so much money. In addition, it was very rare for her sister to change the ground source heat pump equipment from Chen Xin.


    After thinking about it, Chen Xin decided to tell Mo Qingyan what she really wanted to do instead of keeping her in the dark: "in fact, long Niang, you really don''t have to do this. The reason why I do this is to reap a wave of resources from everyone. If you stop me like this, you will scare other people away."


    "Harvest resources? How do you harvest resources? Are you not afraid that people will come to you and kill you when you open the door and take your refuge? " Mo Qingyan looks disdainful and even angry. She thinks Chen Xin has let her down.


    However, Chen Xin just looks at Mo Qingyan''s angry appearance, smiles for a while, and then takes out the pistol Qin LAN gave him from his clothes.


    "This is Guns? Xin, where did you come from? " Seeing Chen Xin take out a gun, Mo Qingyan and Mo Qingxin are shocked.


    Although it''s the end of the world, Yanguo is not a federation where primary school students always carry guns in school. Yanguo''s gun control has always been the most severe country in the world. Except for the police and the army, private people rarely hold guns. Chen Xin suddenly takes out a gun at this time, which is enough to surprise Mo Qingyan and Mo Qingxin.


    "This is a LAN help me get, with it in, at least I still have a certain guarantee of safety." Chen Xin explained the origin of his pistol to Mo Qingyan.


    "Ah LAN is so kind to you? But even if she''s a SWAT, she can''t get a gun, can she? " Mo Qingxin gave out a puzzled voice, full of questions: "before, when Anning lived here, uncle Ding didn''t give her a gun!"


    Mo Qingxin''s question is also Mo Qingyan''s question. She knows that Qin LAN is very kind to Chen Xin. It''s normal for Chen Xin to find a way to get him a weapon for self-defense, but a gun is still beyond Mo Qingyan''s imagination.


    You should know that even the police in Yanguo are not allowed to have access to guns casually. They have strict regulations on the use and management of guns. Every gun has a serial number and is not registered. They even have to write a report for every shot.


    Under such strict control, even if Qin LAN says that she lost her gun and gave it to Chen Xin, it''s impossible, so Mo Qingyan is very curious about how Qin LAN helped Chen Xin get the gun.


    In this regard, Chen Xin naturally can only explain to Mo Qingyan, "I have to trade at least 2000 Jin of vegetables to the special police force every month. A LAN convinced uncle ding that for my safety and to ensure the continuity of the supply chain, he specially gave me a gun."


    "So it is..." The shock brought by a gun is still too strong. Mo Qingyan and Mo Qingxin can''t slow down.


    Before the disaster, if someone said that, they would definitely slap him twice in the face to wake him up. If it was not for the gender, they would have to give each other a little yellow soup.


    Even though it''s the end of the world and the situation is totally different, it''s still frightening to be able to get a gun.


    However, with a gun in the rookie, Chen has opened up a gap with other people in terms of force. As long as he doesn''t wave by himself, or believes that other people will face him, his safety is guaranteed.


    After all, Chen Xin usually lives in the shelter of his own home, with solid and reliable door protection, and no one can hurt him.


    Think of here, Mo Qingyan also understand, a little embarrassed and embarrassed to say: "it seems that I destroyed your plan..."


    As she said this, Mo Qingyan''s face became a little strange, and she was annoyed by her impulsive behavior.


    Chen Xin didn''t mind that. He put the pistol away again and then said with a smile, "it''s not a bad thing. Long Niang, you made such a fuss before. On the contrary, you raised the price of the ground source heat pump equipment. If they want to change it, they have to take out something at least similar to your asking price. It''s not something they will be able to take out for a while."Hearing Chen Xin mention his previous offer, Mo Qingyan''s face suddenly blushes, and her expression becomes more and more embarrassed, especially when Mo Qingxin is standing beside her, which makes her more uncomfortable.


    After all, in the exchange terms Mo Qingyan offered Chen Xin before, Mo Qingxin was also involved.


    In fact, at this time, Mo Qingxin is also very embarrassed. It''s OK not to mention it. When it comes out, both she and Mo Qingyan are very embarrassed.


    Chen Xin seems to be aware of the embarrassment of their sisters and quickly digs off the topic, saying: "long Niang, your previous offer is too exaggerated. You don''t need to exchange so many things for a set of ground source heat pump equipment. If you need, I can accept the exchange ratio of five cases of wine, five cases of canned luncheon meat and two cases of canned pork."


    This exchange rate is half of the price offered by Mo Qingyan before. Although Chen Xin is very grateful for Mo Qingyan''s kindness, he still did not say that he would give Mo Qingyan a set of ground source heat pump equipment for free.


    However, Mo Qingyan shook her head and said, "no, I have air conditioning here, and the city government has not stopped the power supply. Heating is still OK. I said that just to help you."


    Mo Qingyan''s words made Chen Xin frown and ask her, "how long can your supplies last? a year? Two years? "

 Chapter 107

    "I have enough to eat here. Don''t worry. Just Xiaoxin and I will have enough for another three or five years." Mo Qingyan looks confident and optimistic: "after three or five years, the country must have begun to resume production. Even if she has to live underground, it will not be a problem to eat."


    For Mo Qingyan''s optimism, Chen Xin saw her guilty, but friends should not force others to accept your kindness, so Chen Xin did not continue to ask, just said to Mo Qingyan: "since you have said that, I will not force you, if there is any need to help, please contact me at any time. Besides, you... "


    Chen Xin hesitated for a moment, but still said to Mo Qingyan: "although long Niang''s reserves must be enough for you to eat, now is the end of the world after all, and no one knows what will happen in the future. I suggest you build a planting greenhouse with certain self-supporting ability, which can make you stick to it for a longer time and improve your life."


    As for Chen Xin''s proposal, Mo Qingyan has considered it before. After all, no matter how much food is reserved, there will be a day when the food is finished. She always has to make plans after the food is finished.


    "Food materials, your proposal is very good, but the problem is that I really can''t afford to plant greenhouses! Before, she told Alan that she wanted to grow mushrooms. Later, she asked someone to help her. She said it was not suitable for transformation, so I didn''t do it. " Of course, Mo Qingyan knows what she should grow, but she really doesn''t have the conditions to grow mushrooms.


    Although Mo Qingyan''s shelter has good thermal insulation and air conditioning, which can ensure that the temperature in the shelter will not be too low, there are many deficiencies in terms of mushroom cultivation.


    "Can''t you grow mushrooms? This... " Chen Xin frowned and thought about it, and said to Mo Qingyan, "since you can''t grow mushrooms, you''d better do hydroponic cultivation like me, long Niang."


    At this point, Chen Xin went over his thoughts in his mind and explained his thoughts to Mo Qingyan with a little excitement: "I''ll help longniang install a set of ground source heat pump equipment, and then connect this set of equipment with a fish vegetable symbiotic hydroponic planting system and waste heat recovery power generation device.


    So you can get energy through the ground source heat pump, which can generate electricity and heat, keep the whole system running, and produce food to you continuously


    "Is that really OK?" Mo Qingyan was also moved by Chen Xin''s description.


    Chen Xin said that this system is really beautiful, because it can generate electricity, heat and produce food. It can be said that with such a system, Mo Qingyan''s shelter needs not worry about heating and eating at least.


    Facing Mo Qingyan''s question, Chen Xin nodded for sure: "the ground source heat pump device can achieve an energy efficiency ratio of 4. If part of the energy is recycled for power generation, it will be enough to drive its own operation, and at the same time, it will have enough heat output.


    As for the hydroponic cultivation of fish and vegetable symbiosis, as long as the temperature is guaranteed, it''s still very easy to get. I''m going to get a set of such equipment myself, so long Niang, you can rest assured. "


    "In that case..." Mo Qingyan nodded, as if she had been agitated by Chen Xin: "let me think about it. After all, it''s a big project to make this, and you don''t even have a set of equipment for the food now, do you?"


    As for Mo Qingyan''s question, Chen Xin just said with a smile, "if necessary, the equipment can be ready at any time."


    "Well, let me think about it and get back to you." Mo Qingyan still didn''t agree directly.


    Chen Xin just nodded and said nothing more.


    When Chen Xin returns to his refuge, he contacts Qin LAN and asks her to exchange materials including drills and compressors.


    "Ah Xin, why do you want these things?" Qin LAN heard Chen Xin want things, and did not immediately agree, but asked his use: "you want these things we special police team does not have in stock, I''m afraid to go to collect to get you."


    "I''m going to use these things to build a ground source heat pump for my shelter." For this, Chen Xin has nothing to hide from Qin LAN.


    When Chen Xin said that he wanted to assemble the ground source heat pump, Qin LAN didn''t know what was going on. Chen Xin''s patient explanation made him understand what was going on.


    "So it is. I''ll ask the team leader later. In addition to the drill, many of the things you want are not easy to get now." Qin LAN is not sure that she can help Chen Xin get things.


    Although Chen Xin basically has all the things he wants on an air conditioner, and he can easily buy them before the end of time, it''s hard to get them in the end of time.


    Although the country is in the process of industrial restart, it is obvious that all production capacity is given priority to supply the most needed places. The first thing to resume production must be the basic industrial facilities, such as Chen Xinyao''s compressors and evaporators. Now, even if they are produced, they are also for large-scale industrial use.


    In other words, these products will be sent directly to factories where production is resumed, rather than sold to individuals.So if you want to get these things, even the SWAT team can only collect a little bit.


    At the end of the call with Chen Xin, Qin LAN naturally reported the news to Uncle Ding for the first time.


    "Political commissar, what do you think?" Uncle Ding looks at the Commissar. When Qin LAN comes, they are just talking about things.


    Uncle Ding always used to ask the political commissar''s opinion about such things that needed to be decided and judged.


    "I also know something about this kind of ground source heat pump equipment. It seems that during the 13th five year plan before the disaster, there were three heating projects applying this technology in our city, but the meteorite fell down before the completion." The political commissar knew something about this kind of technology and equipment, thought about it for a while, and replied, "if Comrade Chen Xin can really transform this kind of thing himself, I think we can help, and by the way, we can change some equipment."


    After listening to the political commissar''s advice, uncle Ding naturally understood the old man''s meaning: "political commissar, do you mean we also use this?"


    "If a snowstorm cools 30 degrees, the temperature may be even lower in the future. Although there is still power supply in the urban area and boilers in the shelters, all the coal is transported outside. What if the railway transportation is interrupted? There has to be a backup. " The commissar looked at Uncle Ding and said with burning eyes.


    After listening to the political commissar''s suggestion, uncle Ding nodded and said to Qin LAN, "in that case, Xiao Qin, please tell Lao Li and let him take people out to collect materials."

 Chapter 108

    In an abandoned community, Li Tou and his team are collecting materials in a residential building.


    "Li Tou, there''s another air conditioner that''s not burnt out!" A special police team member found an air conditioner that had not burned down, and quickly informed Li Tou.


    "Where is it? Take it down and take it away When Li Tou heard the report from his subordinates, he hurriedly looked at it, but he did not forget to give instructions.


    In addition to the snow, the strong wind also damaged many things, and even some buildings collapsed, which was comparable to the passage of a typhoon.


    After losing the deceleration effect of surface vegetation on wind, the harm of strong wind is also rising.


    Some of the buildings damaged by the previous fire in the urban area have collapsed in the blizzard, while the rest are still standing, but also severely damaged.


    Things such as air conditioners, windows and so on were basically blown away, and many of the things left in the house were literally swept away, which hindered them from collecting materials.


    Fortunately, this time they came to a community with relatively good building quality. Most of the buildings were not seriously damaged, but the glass was blown away.


    But even so, the search is difficult.


    Most of the external units of the air conditioner have been damaged, and the installation location of the external units of the air conditioner is the external wall of the building. Even if there are no damaged ones, it is a troublesome thing to remove them.


    In addition, it''s freezing now, and the snow on the ground can bury people. They have been here all morning, and only a few complete air-conditioners have been found.


    Although the Blizzard has stopped, but the temperature did not significantly pick up, the temperature of more than 20 degrees below zero, even just breathing can make the mask frozen.


    In such an environment, these SWAT team members have to climb to the outer wall of the building to remove the air conditioner, which is really not a matter of fooling around, and there is no way to deal with low efficiency.


    "Li Tou, it''s too inefficient to look for it like this. Let''s take down the bad ones that are not too serious. There are some useful things in them." A member of the special police team is giving advice to Li Tou.


    In the face of this special police member''s proposal, Li Tou just frowned and thought for a while, then asked: "how many units have been dismantled?"


    "There are eight in total. Three are in good condition. Four are damaged but can be used. One has no shell but everything is there." Another special police team member has been counting their harvest. At this time, Li Tou asked and soon gave the answer.


    Li Tou, who got the answer, could not help but gnash his teeth secretly, feeling a burst of annoyance.


    Although Taiwan''s achievements are not small, the political commissar told him to find more before he came here. That''s why Taiwan''s mission can''t be regarded as completed in any case.


    After thinking about it, Li Tou hesitated for a moment, but still said to the special police around him: "in the afternoon, let the brothers take down the bad ones that are not serious. This thing is not enough to go back to hand over."


    "Yes, Li Tou!" The Swat member answered and relayed Li Tou''s instructions over the radio.


    Looking at the busy look of his team members, Li Tou himself also turned on the radio and said: "after dismantling the hand of this machine, we first eat, eat enough, and strive to find more in the afternoon."


    Hearing that they could have dinner, the team members couldn''t help but cheer up and speed up their actions. Obviously, they wanted to have dinner early.


    Perhaps because of the temptation of lunch, everyone''s action became a little faster. The relatively intact external plane found was quickly removed, and the special police team members also returned to the police car to prepare for dinner.


    "Li Tou, what are we looking for these old air conditioners for? Don''t you want to use it to warm the shelter after repair? " Holding a self heating food and adding water to heat it up, an SWAT member asked Li Tou what they were doing to collect the external unit of the air conditioner while tossing his lunch on his hand and warming his hands by the way.


    "If you want me to tell you, it''s the most reliable way to burn a boiler. If the air conditioner is cut off one day, don''t you still have to be frozen?" Another special police officer put the hot self heating food on his knees and covered his knees, and he also interrupted: "but this day is really evil. Our city didn''t snow in winter for more than ten years before, and it snowed a little more in these two years."


    "Thought it was before? The sun is gone. It''s snowing. What''s the matter? " Li Tou, like his team members, was holding a bag of self heating food and waiting for the meal to be cooked. When he heard their discussion, he couldn''t help saying something.


    "Well, I don''t know when this day will end." The members of the special police who were pouring self heating food suddenly became depressed.


    It''s been almost half a year since the meteorite impact. However, in the past half a year, everyone''s life has gone from bad to worse. Who can live a life with no hope and no future?


    Hearing the despondent words of the special police member, Qin LAN takes her lunch and somehow remembers what Chen Xin said to her before the end of the day.


    "The impact of meteorites is just the beginning. The dust will cover the whole sky. The absence of the sun for a hundred years will not only freeze the earth, but also make the ecology extinct. Maybe in one to three years after the impact, part of the dust in the sky will fall, making the sky faint. But it will take at least a hundred years to recover to the way it was before the disaster."Unknowingly, Qin LAN even retells Chen Xin''s words.


    "A hundred years? Doesn''t it mean we''ll never see the sun in our life? " Qin Lan''s words immediately let the special police team members who eat in the carriage silence down.


    One hundred years is really short for the earth, not in a short moment. This apocalyptic disaster for the planet under our feet, I don''t know how many times it has experienced in its long 4.6 billion years, which is really small and not worth recording.


    Only those ancient biologists who study fossils can trace back to such a tiny trace.


    But a hundred years, for mankind, is how long!


    Life is rare since ancient times. It''s difficult for a person to live over a hundred years, even in peaceful times. What''s more, it''s the end when everyone is struggling to survive?


    "Why are they all down in the dumps? Now we have food, drink and a place to live. What''s the dissatisfaction? " Li Tou looked at the players in such a low mood, and immediately yelled at them.


    "Li Tou, I can''t see any hope these days!" One of the SWAT team members showed a bitter smile on his face and looked up at him: "do we live underground all our lives? We don''t care, but it''s impossible for the next generation to live such a dark life, right

 Chapter 109

    Listening to the words of his subordinates, Li frowned and said to them, "what''s the environment now, don''t you know? Hope to see the sun, can you go up, or can you let the black clouds set down? If you have the spare time to think about it, it''s better to think about how to find more resources in the afternoon to complete the task. "


    Of course, Li Tou understands why these players are so depressed. If we just live in a shelter, we can tolerate the bad environment.


    But now, with the coming of the snowstorm, the temperature has dropped further, and even the official shelter, the living environment has become worse.


    Low temperature brings not only cold, but also other associated problems, some of which need to be faced by shelter managers, while others need to be borne by every survivor.


    Originally, we were already a little overwhelmed after the end of the world, but now new pressure has been added, and some people with poor psychological endurance can''t bear it and begin to collapse.


    In the past six months, although the shelter has been thinking of various ways to relieve the pressure and reduce the psychological burden, some people have been unable to bear the pressure and choose to end their lives, and even some people have an antisocial tendency, causing violent incidents in the shelter.


    If the grassroots police and special police teams in various shelters are not handled in time, mass incidents may also occur.


    Now these SWAT members are just depressed and depressed, which can be regarded as a very normal performance.


    But Li Tou understood, but there was no good way to boost his morale. He even had to cheer these people up to finish their work in the afternoon.


    Li said that everyone could only eat more quietly, and the atmosphere in the car became more depressed for a moment.


    Seeing this situation, Qin LAN hesitated, came to Li Tou and whispered to him, "Li Tou, this is not the way to go on! People are in such a low mood that there will be problems. "


    Why didn''t Li Tou know that something would go wrong? But if he had a way, he would have used it for a long time. How could he make the whole team demoralized now.


    Qin LAN saw that Li Tou was silent and didn''t speak. After thinking about it, she said, "would you like to gather something to change the bar?"


    "Wine? Xiao Qin, do you know where I can get some wine? Don''t drink, let''s smell it! "


    "Don''t mention wine! I haven''t drunk for more than half a year. I''ve almost forgotten what wine is. When you talk about it, I''m a wine bug


    "Is sister LAN real? I haven''t tasted wine in half a year! If I can drink some wine, let me donate my rations and chew the mushrooms for half a month


    Qin LAN just said a word of wine, suddenly everyone was excited, and asked Qin LAN how to make wine, even a few people have begun to gather their own things, in order to make wine.


    Li Tou also attaches great importance to Qin Lan''s idea of changing wine. If he can get one or two bottles of wine to make his subordinates addicted to alcohol, it will be very helpful to improve their morale.


    This point can be seen from their current picture of wine insects in turmoil.


    Under the current situation, food is already very valuable, and wine making has obviously become impossible.


    Although various shelters have already organized scavenging teams to collect resources in the ruins of the city, wine is still hard to find.


    It''s as rare as two six-star officers in a company.


    So even if there is a black market, if you want to buy wine on the black market, the high price makes the Swat members flinch. That is to say, the black market itself is a scarce commodity with price but no market.


    "Xiaoqin, can you really get wine? How many things do I need to exchange? Is it going to the black market? " Li Tou looks at Qin LAN quite seriously, and at the bottom of his heart, he is calculating how many things he can take out for wine.


    Li Tou is addicted to alcohol. He used to like to drink two cups when he was free, but now


    But he is not the only one who hasn''t smelled alcohol for more than half a year. Before, it was revealed that some people went to the infirmary to steal medical alcohol and water to sell it as wine.


    "I know a friend who opened a bar before the disaster. She has a lot of wine in her house. You can exchange it with her." Although Qin LAN knows that Mo Qingyan''s family has wine and many good ones, she never tries to find Mo Qingyan to buy wine.


    The reason is very simple. First, it''s too expensive to buy. Second, although Qin LAN drinks, she is not addicted to alcohol, so she has no demand for it.


    When Qin Lan said that he knew his friends and had wine at home, everyone''s eyes lit up. In addition, the light in the car was dim. Qin LAN even thought that what he saw was a group of wolves. These people''s eyes were green.


    "Xiao Qin, ask your friend what you want for two bottles of wine. If the price is right, let''s get together and help you get it later. Do you think so?" Li Tou looks at his men, who are about to turn into werewolves. He shakes his head helplessly and swallows the saliva in his mouth. Then he asks Qin LAN about it.For Li Tou''s request, Qin LAN didn''t refuse, nodded and said: "after I go back, I''ll ask my friend. It shouldn''t be too expensive. Ah Xin used 200 Jin vegetables to exchange a box of wine from her before."


    Hearing this, everyone in the car felt relieved. Two hundred kilograms of vegetables for a box of wine, even six bottles for a box of wine, was not too expensive. They could still get together to exchange two bottles of wine.


    It''s confirmed that we should gather something to exchange wine. The atmosphere in the car has also warmed up a lot. There are also some smiles on everyone''s faces. They are no longer as sad as before.


    Looking at everyone''s morale rising, Qin LAN is also slightly happy. She is all her comrades in arms, and she doesn''t want to see everyone dejected.


    Thanks to the success of this event and the blessing of having a full lunch at noon, everyone has also burst out with enthusiasm for work, and the speed of collecting resources in the afternoon has been significantly accelerated.


    And these special police team members also learned from Li Tou why they wanted to collect these things. After knowing that they wanted to use them to make heating equipment, they also took a lot of care. They also took a glance at the burned debris in the morning and turned it into a more careful look.


    By the end of the work, they found 13 fairly complete air-conditioning units and about 20 air-conditioning wrecks that were not so badly damaged and could be removed.

 Chapter 110

    When the special police team helped Chen Xin search for raw materials for ground source heat pump equipment, several friends in the survival group were not idle.


    Although Mo Qingyan''s offer stopped many people before, a set of equipment that can continuously heat in this environment and still consumes low energy is still something that makes everyone excited.


    Their hesitation and hesitation is only because they are worried that they can''t bring so many materials to trade with Chen Xin, and they can''t find the materials to make the equipment.


    However, since these groups of friends can build their own private shelters instead of crowding the official ones, they naturally have some family background.


    In addition, they see the opportunity early and like to live outdoors. In fact, most of them still have a lot of materials on hand.


    If you really want to bite your teeth, they are not unable to take out the price Mo Qingyan offered before. They just need to weigh whether it is worth it or not.


    What really restricted them from trading with Chen Xin was the materials for manufacturing equipment.


    Even the special police force has to collect materials to collect materials. Naturally, these private shelters can also be imagined.


    However, among these people, Li Wensheng has the most advantage. His shelter is built under the original villa, surrounded by villas, so it''s much more convenient to find air conditioning than others.


    Even when Li Wensheng''s villa is initially equipped with household central air conditioning, the materials Chen Xin needs to make ground source heat pump equipment can be directly removed from above.


    Although Li Wensheng thinks so, it''s a pity that it''s not just his family. Most of the external air-conditioning units in his villa area are seriously damaged. He only found two relatively good external air-conditioning units after searching the whole community.


    After installing the two air-conditioners into his car, Li Wensheng moved his hands and feet, which were very cold, and said to his son, "OK, Xiaohai, go to the storage room and have another box of compressed biscuits."


    "All right, Dad." Li Wensheng''s son Xiaohai nodded, turned back to the basement of his villa, and resisted a compressed biscuit.


    He took the box from his son and put it in the trunk of his car. Looking at the things loaded, Li Wensheng said to his son, "go back first, Xiaohai. It''s cold outside."


    "Dad, be careful on the way!" Xiao Hai hands a flashlight to Li Wensheng and watches him get on the bus. Then he goes into the basement of his villa and closes the door.


    Watching his son close the door, Li Wensheng safely starts the car and drives to the outside of Chen Xinjia''s city.


    "Fortunately Xiaohai can help now, otherwise..." While driving, Li Wensheng also sighed.


    Li Wensheng was a farmer when he was young, but he had a bright head. He didn''t work hard in that area. In his early years, he went out to work and opened up his horizons in coastal cities. After earning some money, he came back to his hometown to contract land and set up greenhouses. He was the first person in his village to become well-off.


    Li Wensheng is not a man of peace. After the rise of hydroponic cultivation technology, he started hydroponic cultivation again. But this time, instead of planting his own land, he sold the technology.


    It has to be said that in those days, the adventurous people at least had their unique vision and courage. With a little ability, it was not difficult to succeed.


    Li Wensheng quickly made a lot of money by operating hydroponic cultivation. He also lived in a villa and drove a luxury car. His life was very rich at first sight.


    As for the problem that a man gets worse when he has money, it''s not his fault. His wife is his childhood sweetheart. He married him when he went out to roam for the first time. He has suffered and been tired for so many years, and the couple''s feelings of sharing weal and woe have also withstood the test.


    Xiaohai is his eldest son and has a younger sister. The two children are young. Even Xiaohai is just 16 years old and is in high school. Her daughter is not nine years old.


    Because of his early experience of going out and wandering, Li Wensheng was a restless person. After he had money, he became addicted to outdoor sports, and naturally got to know Chen Xin and Mo Qingyan.


    Maybe it''s the sense of crisis that he developed in his early years. At the beginning, when he heard that there might be a meteorite impact disaster in the group, he emptied his savings, built a shelter under his villa and stored a large amount of materials, regardless of his wife''s opposition.


    When the meteorite interception plan was successful, his wife complained that he had spent all his family''s money. But when the meteorite really fell, both Li Wensheng and his wife were glad that they had dug a refuge.


    Thanks to the early arrival of the opportunity, Li Wensheng''s refuge is more well prepared than Chen Xin''s, and the heating equipment is also equipped.


    If the three wind turbines he prepared were not broken, Li Wensheng would not worry about heating at all.


    But now, if we don''t solve the problem of heating, he doesn''t have much diesel in reserve. It will be the limit for him to support for three months at most, and this has not included the heating consumption of his refuge.


    Therefore, for the ground source heat pump equipment that Chen Xin said can be manufactured, Li Wensheng has an urgent need.The impact of the sudden drop in temperature is many, and the snow after the Blizzard is one of them. Although Li Wensheng wrapped the anti-skid chain on his tires, in the waist deep snow, even the tires wrapped with the anti-skid chain are still difficult to move.


    But fortunately, the weather is too cold, the snowstorm has been coming for a few days, the snow is basically frozen hard, but there is no risk of sinking into the snow pit.


    Moreover, the snow makes the road smooth. In a sense, it''s much easier to walk.


    In any case, after a long time, Li Wensheng drove to Chen Xinjia''s shelter.


    Snow covered, so that the original prominent shelter door has been buried nearly half, if not Li Wensheng has been here once, and the ability to recognize the road is also good, it is really difficult to find the door of Chen Xinjia''s shelter in the dark snow.


    Through short wave radio, Li Wensheng called Chen Xin.


    The gate of the refuge opened a gap in Li Wensheng''s uneasiness.


    Although snow provides camouflage for the gate of the shelter, it also brings some trouble for the door.


    Fortunately, you don''t need to open all of them, you just need to open a gap, and people can come out from inside.


    "Writer, I have what you want. Can you help me make a set of ground source heat pump?" Seeing the figure coming out of the shelter, Li Wensheng said to him, "I''m not as rich as the landlady in the exchange of goods and materials, but I brought a box of compressed biscuits. This is a deposit. I can take out another box of the remaining balance money and give you ten more fish. Do you think that''s enough?"

 Chapter 111

    He said his offer. Looking at Chen Xin who didn''t speak, Li Wensheng was somewhat worried. Of course, what he took out can''t be compared with the price offered by Mo Qingyan.


    The urban area has now formed a fixed black market, a place where several refuges in the urban area exchange their needs in private.


    Although the government is also aware of the existence of the black market, it has not cracked down on it, but acquiesced in its existence.


    In the black market, the most valuable goods are all kinds of non renewable materials produced before the disaster. Wine is the most powerful goods.


    even if it''s just a bottle of ordinary Baijiu, it can get enough food for one week to eat in the black market, let alone a better wine with higher value. Some even have more than one bottle of rations for a month.


    Although Li Wensheng''s box of compressed biscuits is also in hot demand on the black market, it is far from Mo Qingyan''s ten boxes of wine and ten boxes of canned meat, even one percent.


    Not to mention Mo Qingyan in the price also set up his sister.


    However, the price Li Wensheng offered was not cheap. What was valuable was the ten fish.


    If wine is scarce, meat is really rare. Even in the black market, there is no fresh meat, only canned meat left before the disaster.


    Most of them are pork or luncheon meat, which can hardly be called meat, not to mention fresh fish. This thing is extinct. In addition to the fact that the municipal government may have it in the underground planting areas, Li Wensheng may have it in his hands.


    For Li Wensheng''s offer, Chen Xin just frowned and said, "how many fish were there last time you came to me to change the oxygen generator?"


    Hearing Chen Xin''s words, Li Wensheng''s face turned red like constipation. If he didn''t wear a protective mask and the light around him was dim, he would be ashamed to bury his head in the snow.


    "Then I''ll add some more fish..." Li Wensheng is very embarrassed to raise the price, which is the same thing for him.


    Although he has a lot of fish, he has turned off half of the fish vegetable symbiosis system in order to save electricity, and he does not have many fish on hand. It is his limit to take out more than ten fish to exchange with Chen Xin.


    Fish is not a vegetable in the field. Seeds can be harvested within a month after they are sown, and even can be peeled for longer. It takes at least one year for a fish to grow from egg to adult, and it''s not uncommon for a fish to grow for two or three years.


    Looking at Li Wensheng''s picture, Chen Xin could not help shaking his head and asked him, "old farmer, you should have some extra fish and vegetable symbiosis equipment in your hand, right?"


    Hearing Chen Xin''s question, Li Wensheng was not sure what he meant, but he nodded and said, "there are only spare parts at home. There are not many. But the warehouse I used to store goods in is not badly burned. I''ve seen it before. I can search it and find out about three or five sets of equipment."


    When Chen Xin heard what he said, he nodded with satisfaction: "in this case, take two sets of equipment, plus six males and six females and twelve live fish as seeds. I''ll give you a set of ground source heat pump equipment and help you install it by the way."


    "This..." Li Wensheng hesitated when he heard Chen Xin''s offer.


    It''s not that he can''t afford two sets of fish and vegetable symbiosis equipment, or that he thinks the price is not worth it, but Chen Xin wants to change the fish and vegetable symbiosis equipment, which is obviously for his own use.


    In this way, Chen Xin has the ability to produce fish resources here, which naturally means that Li Wensheng can no longer trade fresh fish, a renewable resource for him, from Chen Xin, or that he can''t start selling.


    But after a little hesitation, Li Wensheng bit his teeth and nodded his head and said, "OK, two sets of fish and vegetable symbiosis equipment, twelve kinds of fish. This box of compressed biscuits I brought is still a deposit."


    Seeing that Li Wensheng was on the road, Chen Xin was a little impressed with him, so he nodded and said, "now that the price is settled, what about the materials? When the equipment is ready, I''ll install it for you later. "


    "It''s in the car." Now that the price has been negotiated, Li Wensheng doesn''t hide it. He takes Chen Xin to the back of the car and points to the things on the car. He says, "there are two external units of central air conditioning. What you want are all on them. What I choose are fairly complete external units. Everything should work."


    Chen Xin nodded, damage to him is no harm, big deal in the workbench with the system repair.


    He asked Li Wensheng to help him clear the snow at the gate. Chen Xin pushed the gate open and carried in two old air conditioners from Li Wensheng''s car.


    It''s also a wake-up call for Chen Xin. It seems that it''s not only the small bunkers with short wave antennas that need to be deicing every day, but also the front door of the shelter needs to be deicing and snow shoveling.


    Unless Chen Xin changes the gate to electro-hydraulic and has the function of deicing and defrosting, it will be necessary to shovel snow and deice.


    After all, although Chen Xin seldom goes out, he still has to go out.


    Watching Chen Xin pull things closer to the shelter and give Chen Xin a box of compressed biscuits as a deposit, Li Wensheng leaves.Although some people are not sure whether Chen Xinhui will take things and not give him equipment, now that he knows that Chen Xinhui''s refuge is here, he is not afraid of Chen Xinhui''s running away. It''s a big deal to come to collect debts.


    After seeing off Li Wensheng, Chen Xin closes the door of the refuge again.


    Although the blizzard stopped, but the sky is still floating snowflakes, which is also the sequelae of meteorite impact.


    Because in addition to the federal one, all three of them hit the Pacific Ocean. A huge amount of sea water was thrown into the sky. Coupled with the evaporation caused by the global fire, the whole atmosphere was full of water.


    A few months ago, Chen Xin didn''t go out. His refuge was built in the mountain, and there was no danger of water entering the gate of the refuge. Naturally, he didn''t feel much about it.


    But in fact, it rained for two or three months. This snowstorm was also caused by too much local rainfall, which caused a sudden drop in temperature.


    Meteorite impact not only obscures the sky, but also collapses the whole weather system after the loss of sunlight. Without the self-regulation of the weather system, extreme weather will only become more and more.


    However, all of these have little impact on Chen Xin, who lives underground. After all, no kind of weather can affect the mountain more than 200 meters.


    However, just as Chen Xin was pushing two external air conditioners into the shelter, a sudden shaking came from his feet, which made him unstable. He held the wall firmly.

 Chapter 112

    It''s an earthquake! Almost without thinking, Chen Xin has already judged what happened.


    However, the intensity of the earthquake is not high, the duration is not long, just a short period of shaking, then stopped.


    However, even so, Chen Xin did not dare to neglect, rushed back to the shelter with two air-conditioners, and then checked the damage of various facilities in the shelter.


    Although the shelter was built according to the highest standards, in theory, even a magnitude 6 earthquake would not collapse, Chen Xin could not tell the magnitude of the earthquake just now.


    What''s more, he''s not afraid of 10000, just in case, if something goes wrong, he doesn''t pay attention to it. It''s really a fatal thing.


    Fortunately, after a round of inspection, the construction quality of the shelter really passed the standard, and there were no cracks or other damages. Even Chen Xin opened the system perspective, and found no place that needed to be repaired.


    "Woo hoo, it seems that the construction team didn''t brag at the beginning. It can really resist the earthquake of magnitude 6." While Chen Xin put some displaced or fallen things back in place, he also praised the engineering team that helped him build the shelter.


    It didn''t take Chen Xin too long to clean up. After reorganizing everything, Chen Xin didn''t have the mood and physical strength to toss about the two air-conditioners he had just collected.


    However, when the two air-conditioners were stacked in the original garage, Chen Xin took a look at the workshop he had converted from the garage and suddenly found that the place was a little small.


    This is just a parking space designed by Chen Xin. Although the car has been moved away, the space left is about one and a half parking spaces.


    It''s more than enough to put down a worktable, but it''s a bit crowded to put some other things. In particular, Chen Xingang dragged two air-conditioners back, which made it seem cramped.


    Looking at this small place, Chen Xin didn''t have the idea of upgrading the workshop, but planned to upgrade the storage room.


    Even if the workshop is upgraded, it will also be upgraded in the direction of improving manufacturing and processing capacity. Although the space and area will be improved, the degree of improvement is not too high.


    But now what Chen Xin needs is a place where things can be put. From this point of view, it''s much more appropriate to upgrade the storage room.


    In particular, these two air-conditioners can only be regarded as appetizers, but he also asked the special police for supplies.


    Thinking of this, Chen Xin naturally came to the door of his storeroom.


    In fact, Chen Xin''s storeroom is not large in area. When it was designed, only 10 square meters of space was left.


    There are six simple iron shelves against the wall in the room, which are full of all kinds of food that Chen Xin initially stored, as well as the materials that he exchanged from the SWAT team and Mo Qingyan in recent months.


    In addition to these, the refrigerator he got from Mo Qingyan''s house occupied the most space, which contained vegetables harvested this month and fish that had not been eaten up.


    Originally, it only existed as a food storeroom. Naturally, it didn''t need too much space, just enough to put all the food in.


    However, after Chen Xin obtained the system, the function of the storeroom was not limited to storing food. A considerable part of the materials he exchanged from the special police team through Qin LAN were piled on the floor of the storeroom, making him a little helpless.


    And it''s the result of putting all the cement in the corner of the public space outside.


    "It seems that we need to make a classification, one for food and one for supplies." Looking at the storage room full in front of him, Chen Xin scratched his head.


    Although he is not the kind of hamster who is reluctant to throw anything away and likes to hoard a lot of things, he still has a sense of pride and peace of mind when he looks at the packed storeroom.


    It''s just that this is not the best way to store materials. Chen Xin still plans to store food and other materials separately, and at the same time classify the materials.


    However, the premise is to expand the storage room to at least separate two spaces.


    "Narrow storage room"


    "upgrade scheme 1: expand storage space, increase wall mounted storage rack, extend food storage shelf life, upgrade 800 survival points"


    "upgrade scheme 2: expand storage space, separate material storage room, reduce the aging probability of material storage, upgrade 1000 survival points"


    upgrade consumption is not big, and Chen Xin sees it For a moment, both of the two upgrading schemes can expand the area of the existing storage room by 50%, but scheme 1 is still a storage room, only adding shelves on the wall to put some things on the wall, changing direction to increase space utilization.


    As for the second plan, the storage room of the original room is divided into two rooms, one is a large room and the other is a small room. The smaller one is used as the food storage room, and the larger one is used as the material storage room.


    At a glance, Chen Xin saw that the two schemes were not bad, and the consumption of materials was not much, so he did not hesitate to upgrade the two schemes at the same time.


    With the consumption of materials and the flash of green light, the storage room in front of us didn''t seem to change much, but there was a door on the innermost wall, and there were several rows of shelves made of long strip boards on the wall. The iron shelves originally placed by the wall were also moved to the middle of the storage room, neatly arranged, and there were also two new shelves.This is not the place where the storage room has changed the most. The food and freezers that were originally placed here have disappeared. Instead, the cement and other materials that were originally placed outside the public space are stacked neatly here, while the steel bars and other materials that were previously stacked on the ground are stacked on the shelves in different categories.


    "Do you bring your own warehouse for the upgrade? It really saved me a lot of work. " Looking at the sorted materials, Chen Xin nodded with satisfaction.


    It really saved him a lot of effort. After all, if he was the only one to tidy up the warehouse, it would be a big project. Apart from other things, it would not be an easy job to move just a dozen bags of cement and a pile of steel bars.


    Go through the shelf to the inside of the storage room, open the new door, show in front of Chen Xin is a new space.


    The area is only about half of the material storage room outside. Chen Xin''s original freezer and food were transferred here.


    Chen Xin is very satisfied with the fact that the temperature of this food storage room is a little lower than that of the material storage room outside, but the low temperature is also more conducive to the storage of food.


    After checking it, he found that all the food was put on the shelf in different categories, so he closed the door and exited the storage room.

 Chapter 113

    The new storage space brought by the upgrade of the storage room did not increase too much, but expanded to five square meters of food storage room.


    However, compared with the original space of 10 square meters, it''s much more spacious for both food and materials. At least Chen Xin doesn''t have to face all kinds of materials.


    Especially for the shelves on the wall, after putting the steel bars and some small parts on the floor, the floor of the storage room is a lot cleaner. Besides cement, there is nothing to put on the floor.


    In this way, a lot of space is made up.


    At least Chen Xin can drag the two air-conditioners piled next to the worktable into the material storage room instead of piling them in the way.


    Drag two external air conditioners into the storage room, Chen Xin returns to the workbench and opens the system interface.


    The worktable produced by the system can not only manufacture all kinds of equipment, but also process all kinds of parts with the help of the system. In fact, it can also be used to disassemble all kinds of things.


    Of course, this is the function of the workbench itself, but with the help of the power of the system, Chen Xin can make the disassembly work easier and recycle resources more efficiently.


    For example, he is now sitting in front of the workbench. On the system interface, he can see the two external units of the air conditioner that have been stuffed into the storage room, and display the status of detachable and recycled resources.


    Obviously, under the great power of the system, Chen Xin can already sit in front of the workbench and directly disassemble the things in the storage room.


    Looking at the external unit of the air conditioner, which was shown to be detachable, Chen Xin just hesitated a little, and then ordered to disassemble it, one of which was disassembled into parts.


    The parts did not appear on the workbench, but were still in the storage room.


    However, after ordering the disassembly, Chen Xin is still very curious to come to the storage room again, and wants to see what is left after the system is disassembled.


    At this time, in the storage room, there was already one less external air conditioner piled up by Chen Xin against the wall, while there were many more disassembled parts in the vacant position on the shelf next to him.


    Chen Xin went to the shelf, picked up the disassembled parts and recognized that it was the compressor, one of the most important parts of the air conditioner.


    This is also a necessary part for Chen Xin to make ground source heat pump equipment. Although there is a system to help Chen Xin to make ground source heat pump, he can''t make these parts because of the insufficient level of the workbench.


    Chen Xin is not surprised by the fact that it seems that some parts of the game can''t be made and can only be acquired by field collection or task.


    In the case of ready-made parts, it is not difficult to build a usable ground source heat pump equipment through the transformation of pipes and the splicing of parts. Even as long as there are no problems with the parts, Chen Xin can assemble the ground source heat pump equipment without the help of the system.


    However, with the tools on the workbench, it''s impossible to build a compressor by yourself.


    Although the compressor used in the air conditioner looks like two long cans connected together, the structure inside is quite complicated.


    Before Chen Xin became a full-time writer and began to write online novels, he also did other jobs. Because of his work, he also came into contact with mechanical manufacturing.


    He clearly knows that the manufacturing of a compressor can not be done by hand workshop. Even if the compressor is disassembled into parts and given to him, he may not be able to install all the parts back as they are.


    In other words, even if it can be installed back, Chen Xin is not sure whether the compressor can still be used.


    Because the compressor is in a high-pressure state when it is working, in this case, even if it is just a leak or the assembly is not in place, it may turn the compressor into a bomb, causing serious consequences.


    Therefore, the manufacturing and processing of this kind of thing needs the real industrial level processing and manufacturing capacity, not the garage manual workshop.


    Chen Xin doesn''t really care about this situation. He doesn''t have a high demand for the parts of this kind of equipment. Relying on the materials that the special police team can provide, it is enough to meet his needs.


    Moreover, with the system, Chen Xin can finally produce the parts and equipment he needs by constantly upgrading his worktable and workshop if he really can''t get them.


    Chen Xin, who was already in no mood to work, looked at the disassembled parts, and somehow got excited. He went back to the workbench and planned to manufacture the first ground source heat pump.


    Ground source heat pump equipment is not as systematic as the gun drawings on the workbench of the weapon cabinet, which can be referred to by virtue of the powerful function of the system.


    The ground source heat pump equipment without drawings and references needs to be assembled bit by bit by Chen Xin himself. All the system can provide is some assistance.


    Just as Chen Xin built an oxygen generator before, the system can help him process materials and improve the accuracy and quality of parts at most, but it can''t replace him to directly process materials into parts.


    Although the structure of the ground source heat pump system is a bit complicated, Chen Xin''s notebook has the relevant structure flow chart and general circuit diagram. Compared with the drawings, Chen Xin can still assemble the whole equipment.Although it can be installed, the things Chen Xin assembled are still rough.


    And one thing Chen Xin didn''t think of before is that the refrigerant used by ground source heat pump equipment in the information he saw is usually water, unlike the chemical refrigerant used by household air conditioning.


    Water is a medium with the highest latent heat of evaporation in nature, and the heat carried from liquid state to gas state is also the largest. However, it is not suitable for small household air conditioners to use water as cooling circulation medium.


    The refrigerants used in household air conditioners are chemical media with small volume and fast effect, which can vaporize and condense at room temperature.


    As for the use of water as the cooling medium of air conditioning is not without, large central air conditioning or similar to ground source heat pump need cooling medium to carry more heat in the workplace, the advantage of water is reflected.


    In fact, it is just like the difference between small trucks and large trucks. Small trucks pull less, but the speed is fast and flexible, which is suitable for small-scale use; while large trucks pull more, but the volume is large, and the speed is slow, which is suitable for large-scale use.


    However, now Chen Xin does not consider directly replacing the remaining cooling medium in these equipment with water. Instead, he will assemble the equipment first.


    After all, this is only the external unit of the household central air conditioner. The cooling circulating medium used in it is still chemical medium, which leads to the fact that its circulating pipeline is very small. The evaporator and condenser are also designed for chemical medium, which is not suitable for water.


    If Chen Xin didn''t have a system, he couldn''t do it even if he wanted to, but with a system, it wouldn''t be too troublesome to modify the cooling medium.

 Chapter 114

    "Simple ground source heat pump"


    "upgrade scheme 1: replace the circulating medium, improve the heat exchange efficiency of equipment medium, upgrade the required survival points of 300"


    "upgrade scheme 2: replace the circulating medium, improve the circulating efficiency of equipment medium, upgrade the required survival points of 500"


    the ground source heat pump equipment assembled by Chen Xin is still an ugly guy, but compared with the original one The ground source heat pump equipment at least looks like a pile of things put together by the oxygen generator, so it doesn''t seem to be too crude and shoddy.


    Seeing the upgrade scheme displayed in the system, Chen Xin just picked his eyebrows and then confirmed the upgrade. He applied the two upgrade schemes to the ground source heat pump equipment.


    As the green light is still flashing, the whole GSHP equipment seems to be transformed, and the volume and structure of the equipment itself have also changed.


    Generally speaking, things are getting bigger, pipes are getting thicker, and structures are becoming more complicated.


    Or it can be said that what Chen Xingang just made is just a thing that can be barely called ground source heat pump, and the upgraded equipment is the real ground source heat pump equipment.


    But looking at the pile of pipes on the ground, Chen Xin can''t help scratching his head. Qin Lan''s drill hasn''t been delivered yet. How can he install it in the ground?


    The pipe part of ground source heat pump equipment is a very large structure, although because the equipment is not installed, a large number of pipes are just stacked together.


    However, looking at the large number of pipes, Chen Xin still feels a headache, which is different from what he expected. These pipes are assembled like a huge radiator. It''s not like a hole on the ground can be plugged in!


    Just when Chen Xin felt embarrassed, the system once again highlighted the sense of existence.


    "Is it necessary to consume 50 survival points to install ground source heat pump?"


    Looking at the system prompt that appeared in front of him, Chen Xin scratched his chin. Some days he didn''t shave, but he couldn''t help it, but the point is not here.


    "Is the system so powerful? It''s true that you can do whatever you want with survival! " Chen Xinmo rubbed his chin. Although he knew the power of the system for a long time, he still felt that he had not given full play to all the functions of the system.


    He had thought about installing the equipment through the system before, but Chen Xinna planned to put the ground source heat pump he had assembled into the planting greenhouse, pretending that after the installation, he would use the power of system upgrading to make the equipment installed in place.


    It''s not like now, the equipment is placed here, and the equipment can be installed in place by clicking directly with the system.


    However, since it has such a convenient function, Chen Xin didn''t bother himself, so he chose to consume survival to install the system.


    As for the installation location of the equipment, Chen Xin chose it next to the wall of the public space near the planting greenhouse, and connected a radiator to the planting greenhouse.


    The installation interface of the system is similar to the display interface of some operation and construction games, which is a green grid like virtual interface.


    Chen Xin tried. In this interface, he can move or adjust the structure of the refuge and the placement of objects at will, which is completely controlled by his mind and does not need his extra operation.


    Through this interface, Chen Xin can adjust the building structure and the location of objects in the shelter that he feels dissatisfied or inconvenient. He can even enlarge or reduce the area of the room, and even divide the functions. It is very convenient and powerful.


    Of course, such a convenient and easy-to-use function is also built on the consumption of survival.


    Chen Xin just adjusted and moved a few rooms, changed the location of the equipment, in the system display interface, the survival needed to achieve these changes is more than 1000 points.


    Looking at the numbers displayed by the system, Chen Xin had to give up the idea of adjusting the structure of the shelter and the location of the equipment. He just installed the ground source heat pump and closed the interface.


    Obviously, this interface is not what Chen Xin can afford.


    After installing the ground source heat pump equipment, looking at the ground source heat pump that occupies a considerable part of the public space, Chen Xin thinks that he should upgrade the whole shelter as soon as possible, or save enough survival to adjust the building structure and equipment placement of the shelter.


    Otherwise, he felt that his refuge would only get more and more crowded.


    Install the ground source heat pump in place, turn on the power and let it run. Chen Xin soon feels the heat emission next to its radiator.


    Set the temperature to 20 ¡æ on the control panel of the ground source heat pump equipment. After checking, Chen Xin took out today''s dinner from the newly added food storage room and prepared to eat.


    Today, Chen Xin''s food is very simple, just a shelter ration, plus a can of luncheon meat.


    Chen Xin simply fried the lunch meat, put the shelter rations in the pot and heated them, then sat down on the sofa with the pot and began to eat.


    After such a busy trip, even with the help of the system, Chen Xin still feels very tired.Eating slightly coarse food, Chen Xin has no reason to miss his mother''s sweet and sour ribs.


    It''s Chen Xin''s favorite dish from childhood to adulthood. The fresh and tender pork chops are cut into sections, boiled, fried, cooked in sweet and sour sauce, thicken once before leaving the pot, and then sprinkle with scallions


    When Chen Xin was a child, he could eat a bowl of rice even if he had no meat and only a bowl of rice with thick sauce.


    Thinking, Chen Xin''s eyes can not help but shed tears, dripping into the rice.


    His mother is now far away from home, more than 600 kilometers away, across the four provinces of Hunan, Hubei, Anhui and Jiangxi. If there is no system, Chen Xin is afraid that it would be extravagant to see his mother again in his life.


    Although Chen Xinqiang forced himself not to think about these things, his tears could not stop flowing and his missing for his mother could not stop pouring out.


    His parents are too far away. Even if he has a radio station, Chen Xin can''t talk to them. His hope of seeing them again in this life is slim.


    The spoon in his hand seemed to be very important. Chen Xin''s hand holding the spoon was always unable to lift up and sent the food into his mouth.


    At this moment, what he is thinking about is not eating, but whether his parents, more than 600 kilometers away, more than 1200 miles away, are OK.


    Unable to stop missing, Chen Xin simply dropped the spoon in his hand, pulled a piece of toilet paper, casually wiped the tears on his face, came to the bedroom and turned over the photo album that had been locked in the box.

 Chapter 115

    A little trembling fingers opened the album, which is a yellow old photos.


    Most of these old photos were taken by Chen Xin''s parents when they were young, because later, when Chen Xin went to university, digital cameras began to rise, so it was no longer popular to keep photos.


    Gently stroking these photos, looking at the high spirited and flourishing parents and just a little child himself, Chen Xin''s face was filled with more tears.


    Everything in the photos has long been a memory, and even the place where these photos were taken no longer exists. It''s hard to find. I have grown up to the age of my parents in the photos, and my parents have gray hair and old face.


    The greatest regret and sorrow in life is that a son wants to be raised but not treated by his parents.


    Fortunately, Chen Xin does not have the chance to see his parents again, as long as he can cross the thousands of miles in front of him.


    After wiping away the tears from her face and looking at the old photos and the parents above, Chen Xin bit her lip and determined to go back to her hometown to find her parents.


    After tearing a piece of paper from his notebook, writing down the four words "I want to go home" and pasting a family photo on the paper, Chen Xin pasted the paper in the most prominent position in the living room.


    Chen Xin, who is firm in his goal, looks at his parents in the photo. There is no sadness in his eyes, and some of them are firm.


    it is by no means an easy task to cross 600 kilometers, four provinces and return home to pick up your parents in the present environment.


    Of course, it''s not impossible to imagine. Although it''s 1200 kilometers to and fro, which adds up to nearly 3000 miles, even before the disaster, it will take one day and one night to drive, and even eight or nine hours by train, it doesn''t mean that the traffic is completely cut off now.


    According to the news Chen Xin heard from Qin LAN, although the national railway network and highway network have been greatly affected, the railway trunk lines connecting the provinces are still unblocked.


    As the north gate of Hunan Province, the city is an important land and water transportation hub connecting Hunan Province and Hubei Province. Even in this situation, a train full of goods and materials will come from Hubei Province every week to provide goods and materials for the city, the capital of Hunan Province and the surrounding counties and cities.


    Although we don''t know the traffic situation between Hubei Province and Anhui Province, since the railway between Hunan Province and Hubei Province is unobstructed, there should also be operational railway lines between Hubei Province and Anhui Province.


    If Chen Xin just goes back to his hometown to pick up people, without considering the system, it is his best and only choice to get on the train to Hubei Province.


    As for going by car on high speed Not to mention that the highway is still impassable, it''s just that it''s a fatal thing to drive more than 600 kilometers and then drive back in this weather of tens of degrees below zero.


    The slightest carelessness is car damage and death.


    And it''s not known whether the car can go all the way, not to mention the dark visibility outside.


    Even if Chen Xin wants to choose a road, he can only transform his car into an all terrain vehicle with the help of the great power of the system, and then he can consider choosing a road.


    However, although the road is difficult, if Chen Xin wants to return to his hometown to pick up his parents, he may really have to choose the road.


    Under the current situation and the general environment, it is obviously impossible for the railway to have passenger transport. Moreover, at the end of the day, it is too late for ordinary people to escape from the difficulties. Who will go far by train?


    So even if Chen Xin may get a train ticket through Qin LAN or the special police team, he probably won''t choose to take the train, but drive back to his hometown by road.


    Of course, the SUV in his garage can''t be driven back. Even before the disaster, he started from the city with a full tank of oil. If he wanted to go to his hometown, he would definitely have to add oil once, otherwise he couldn''t get home.


    And now in this case, where can there be a gas station on the road? It can''t be said that oil is on the road in barrels. When there is no oil on the road, pour it into the mailbox, right?


    In that case, in addition to filling up the car itself with fuel, Chen Xin should at least carry enough oil to fill two fuel tanks on the car to ensure that he can drive the car past and back.


    So to drive back, Chen Xin has to upgrade his car, either increase the fuel tank or change the power.


    Increasing the fuel tank is a solution. Although carrying more oil also means that the load of the car is higher, adding more water and adding more water is really a solution.


    For another kind of power, it is expected that the system will be upgraded to energy sources that can be used for a long time, such as nuclear batteries.


    Nuclear battery is not something only in science fiction. Its official name should be radioisotope battery. As early as 2012, a nuclear battery that can last for 14 years was installed on the federal launched Mars rover curiosity.


    In the field of aerospace, this technology is also gradually widely used.


    Chen Xin thinks that if he can install such a nuclear battery in his car, it should be enough for him to go back from the city to his hometown.Curiosity Rover weighs 3893kg. Since the nuclear battery can drive it to run, and its service life is as long as 14 years, it is not a problem to drive a car.


    However, human beings have not been able to apply this device to cars. As for the reason The total investment of the curiosity Rover project is $2.6 billion.


    Of course, for Chen Xin, who has the system, he only cares about how much survival it takes to upgrade his car to nuclear power.


    Despite his strong yearning for his parents, Chen Xin didn''t mean to leave immediately.


    Now the conditions of his shelter are not perfect. First, there is no place to live. Second, the shelter is not enough to bear the consumption of three people. He must at least upgrade the shelter as a whole, so that more people can live in the shelter and produce more food. Then he can consider bringing his parents back.


    Although it is more than enough for one person to manage his own life now, it will be three times more than Chen Xin''s consumption after bringing back his parents.


    If you are not prepared, bringing your parents back is just to make your life worse and let your parents suffer with you.


    Therefore, despite his firm determination to take back his parents, Chen Xin decided to make all the preparations first, and then carry out the plan of taking back his parents.


    After writing these things on the paper with a picture of his family, Chen Xin looked at the picture and touched it. He was more determined to take his parents back.

 Chapter 116

    "Ah Xin is back. Wash your hands and eat!" "Mom, I came first in my class in the final exam!" Hazy, the memory of the mother''s cry is so familiar and strange.


    "My son is wonderful! Dad will take you swimming this weekend His father always regarded himself as the pride of his life, but Chen Xin did not remember when his father no longer praised him.


    "Dad, I want to buy an astronomical telescope. I promise I can get four A''s at the end of this semester!" When I was a child, I always yearned for the sky. What was my ideal at that time? astronomer? astronaut? At that time, everyone seemed to think about the same thing.


    "Son, you should take good care of yourself when you are outside. If you don''t have enough money, please tell me." He was admitted to the University and left home for the first time in his life. His father, who was already white at the temples, stuffed a bank card into Chen Xin''s pocket.


    "Hello, I also belong to this dormitory. We will be brothers in the dormitory in the future." Chen Xin can''t remember who this is in the dormitory, but it should be the eldest brother, right? The oldest, he always takes care of others.


    "Ah Xin, look at that student sister, how soulful! Don''t rob me, I want to chase her as a girlfriend Sister? Chen Xin was impressed by her. He didn''t fight with his brother, but he was still lovelorn.


    "Who''s going to the canteen for dinner? Bring me one! Come on, come on! A point back to defense In the dormitory, a group of naked boys were playing games. At that time, they didn''t even have many notebooks. What were they playing? It''s like CS.


    "Lights out, don''t send messages to your girlfriend!" Someone is checking out the bedroom outside the door. Chen Xin almost forgets that they are not allowed to turn on the lights after 10 p.m. in the University.


    "Senior, do you have a girlfriend? If not, can I be your girlfriend? " This is the first few to express themselves to the younger sister? Since his sophomore year, Chen Xin has been in charge of the work of welcoming new students every year. In addition, he is quite handsome, so he can''t remember how many schoolgirls he has confessed to him.


    "Little Chen Xuedi, do you want to form a club with Xuejie?" Which sister is this? Why don''t you remember?


    "Let''s sing together! Celebrate the founding of our new society When did I form a club?


    "What''s the song? I can play piano accompaniment. It happens that there is a piano here Who can play piano? Why don''t I remember?


    "Can you play" the end of the earth "? That song was very popular a few years ago. " Why did I choose this song? Let''s celebrate the establishment of the new club. Shouldn''t we sing a more festive song?


    "The song adapted from the song of bamboo? I will. I''ve studied the original Japanese. " Sister sat in front of the piano, bright music sounded.


    However, it is strange that Xuejie sang the Japanese version, while Chen Xin sang the Chinese version himself.


    But the two songs use the same song, the melody is the same, so even if the lyrics are not the same, Chen Xin and her piano playing sister still cooperate very well.


    Just as they were singing together, the sound of the alarm clock suddenly broke the harmony.


    Chen Xin wakes up.


    He grabbed the mobile phone on the bedside table and turned off the alarm clock. Chen Xin sat up from the bed.


    The newly installed ground source heat pump has started to work, and now the temperature in the shelter has risen again, which is not as cold as it was a few days ago. Chen Xin doesn''t have to do a lot of ideological struggle in bed to get up every day.


    However, although people wake up, the memories that emerge in the dream make Chen Xin feel melancholy and make him still immersed in those memories.


    Little by little I lived with my parents when I was a child, the friendship I had with my classmates, brothers and friends when I grew up in school, and the people I loved in my life


    Memories are beautiful, but also heavy.


    However, what Chen Xin cares most about is not only his parents, but also the last of his dreams, the elder sister who sang with him.


    Strictly speaking, it''s not Xuejie, because she and Chen Xin are students of the same level, but they are half a year older than Chen Xin, so after they met, she would let Chen Xin call her Xuejie all the time.


    Recalling the high spirited self ten years ago, the things that were worth remembering in school, and the people who were worth remembering, Chen Xin felt that he was attracted by a huge vortex, and his emotions were constantly falling, and he couldn''t get rid of them.


    After brushing his teeth and washing his face, Chen Xin did not go to prepare breakfast as usual, but sat on the sofa with a bit of decadence and darkness.


    Chen Xin is not surprised that he dreams about the past. People''s dreams are related to what they think. It''s normal to have thoughts every day and dreams at night.


    But The people and things in the memories, the places full of memories, have disappeared and can''t go back.


    Looking at the paper he pasted on the wall last night and the goal he set, Chen Xin fell into deep self doubt. Can he really achieve this goal? Can you really stick to it? Does your persistence make sense?Chen Xin is not easily decadent or depressed, but at this moment he is deeply in self doubt and denial.


    He is doubting his ability, his motivation and his purpose of living


    The end of the world is not only an environment of great mental pressure, but also a continuous and almost endless heavy pressure environment.


    In such an environment, the pressure of survival, the loneliness of spirit, the despair of not seeing the future hope


    These emotions are constantly accumulating. Some people have poor tolerance and may soon collapse. But even those with strong tolerance can hardly keep optimistic and positive in such an environment.


    Because there is really no reason to make people optimistic, and there is no future to look forward to that can make people positive.


    Before Chen Xin, perhaps because of the existence of the system, he did not feel so much pressure. He felt that his life would only get better and better, and he was able to maintain an optimistic attitude.


    But when he recalls the past and the good, and contrasts with the loneliness, loneliness, darkness and coldness of the present, the pressure and negative emotions accumulated from the end of the world burst out at the moment, and Chen Xin can no longer hold on.


    He is not a Brooklyn kid who can never be defeated, nor is he the kind of dragon Aotian who can instantly change his mentality from an ordinary person to the one who strives to dominate the world and kill gods and demons.


    Chen Xin is just an ordinary person, who is no different from everyone else. He will cry, be afraid, be decadent and despair.

 Chapter 117

    Chen Xin is just an ordinary person, who is no different from everyone else. He will cry, be afraid, be decadent and despair.


    The only difference is that he is lucky to have a system that can improve the living environment and conditions and can be used as a plug-in.


    The system brings opportunities for change, and change means a better future.


    This is also the reason why Chen Xin didn''t have emotional breakdown before, because the system is like a carrot hanging in front of a donkey, allowing him to move on.


    But carrots are carrots. They are temptations that can be seen but not eaten.


    Perhaps in the long future, Chen Xin has upgraded the refuge to a sufficient level. He can live a good and comfortable life, but now, like others, he is still struggling in this doomsday.


    The future may be beautiful and bright. At last, the donkey may be able to eat the carrot that greeded him all the way, but along the way, it has to endure the temptation that the carrot does not exist all the time.


    Why can''t I stop and finish this carrot before I go on the road?


    Can''t a man be hanged by a carrot like a donkey?


    As soon as this idea appeared in Chen Xin''s mind, it broke out irresistibly.


    Relax, enjoy, let today''s own comfortable, why worry about their own tomorrow? That''s what I need to worry about tomorrow.


    I have to say that this idea is really It''s so tempting.


    For most ordinary people, depravity and enjoyment are too tempting and easy to obtain.


    Under the pressure of life, it''s too hard for us to strengthen our will and live a hard life.


    Compared with indulgence, it''s too hard for people to stick to their beliefs.


    The willpower required is not what everyone or most people have, not to mention that Chen Xin himself is not an ascetic.


    When I think about it, it will grow like weeds and can''t be restrained.


    Chen Xin finally understood why laziness was the second most common sin in Christianity.


    Because for a person, laziness is the most difficult to resist and the most easy to produce emotion.


    Thinking about the fact that he has been trying hard to survive for half a year, Chen Xin suddenly feels that it''s OK to take a day off.


    Forget it. Let''s indulge today.


    Chen Xin gave up the struggle and decided to take a day off today.


    Anyway, it''s the same to do things tomorrow. Why work so hard today?


    To hell with work! I want to play games today!


    Chen Xin takes out the coke he has been reluctant to drink from the storeroom. He is sorry that if there are potato chips at this time, he can''t do any better by drinking coke and eating potato chips while playing a game of gunfight with his friends.


    Unfortunately, now only coke, no potato chips, gunfight game can only play dull stand-alone mode.


    But whatever! There are always some games worth playing ten times, twenty times, even a hundred times!


    Besides, isn''t gunfight just about enjoying the fun of throwing bullets?


    "sister LAN, how long will it take to get there?" On the truck, the young special police who followed Qin LAN to deliver the goods for the first time looked at the dark area outside the window and asked Qin LAN.


    Because of the deterioration of the environment after the blizzard, the special police team was not confident that Qin Lan was driving alone, so they specially sent another person to avoid any danger or difficulty on the road. Qin LAN could not cope with it alone.


    However, there was no problem along the way, except that the snow made the road difficult.


    "Here we are. Ah Xin lives on the mountain ahead." Qin LAN looked up at the road in front of him and answered in a positive way. At the same time, she also looked at the young special police who was driving beside him and said with a smile, "how can I feel far after driving this road?"


    "No, it''s just..." The young SWAT organized the language for a while, but he didn''t know how to say it.


    "Look ahead, concentrate on driving." Qin LAN reminded him, but he also understood his emotion: "it''s easy to feel that I haven''t arrived after driving for a long time in this kind of road condition. But don''t worry, I''ll be there. I''ll turn ahead and drive up the mountain."


    "On the mountain? I see According to Qin Lan''s directions, the young special police are driving along the vaguely recognizable mountain road.


    That''s why he thinks he has been driving for a long time. In this ice, snow and dark environment, they can only move forward slowly, and the road condition itself does not support him to raise the speed.


    Fortunately, Qin Lan said that it was almost there. He drove less than 500 meters up the mountain and saw an iron door half buried in the snow in the headlights."Is that it?" The young special police officer looked at the door, which was almost covered by snow. While confirming to Qin LAN beside him, he also sighed that the place was really inconspicuous.


    If you don''t know the location and have Qin LAN to show you the way, it''s not easy to find the place accurately, especially when the snow is all around and it''s dark.


    "That''s it. I''ll tell him to open the door first." Qin LAN nodded, did not get off the meaning, but took out the shortwave radio, began to call Chen Xin.


    Qin Lan''s call soon got a response, but what made her feel strange was that Chen Xin''s voice on the radio sounded different from usual.


    However, Qin LAN didn''t make a deep study. After all, Chen Xin may be sick or something in this kind of weather and environment.


    She didn''t wait long, and soon the door half buried in the snow opened.


    A ray of light came out from the crack in the door. Qin LAN and the young special police officer saw the door open. Then they put on protective masks and got off the car.


    "Ah Xin, I''ve brought you what you want, but there are a lot of things. I only brought one third of them today, a total of eight air conditioners." Qin LAN greets Chen Xin and introduces what she brought here today.


    However, Qin LAN looked at the door behind Chen Xin with only one crack open, and asked anxiously, "ah Xin, are you blocked by snow? Shall we help clean it up? "


    "I just cleaned it up yesterday. It seems that it was blocked up again last night. It would be great if you could help me clean it up." Chen Xin nodded in a hurry. Although he planned to give himself a holiday today, everything came to the door, and he couldn''t really ignore it and be lazy.

 Chapter 118

    "Ah Xin, do you have to come out every day to clean up the snow? Otherwise, when it snows heavily and buries your gate directly, won''t you be shut down and can''t get out? " Qin LAN shovels the snow and jokes at Chen Xin.


    Although it''s just a joke, her worry is not unreasonable. A snowstorm will make the snow on the ground waist deep, and this kind of weather with continuously low temperature will not melt snow. If there are several more snowfalls, Chen Xinjia''s gate is expected to be completely buried in the snow.


    But for Chen Xin, especially today''s particularly decadent Chen xinlai, it is not something to care about.


    "If you bury it, you can bury it. Anyway, I have food and drink in my shelter. It doesn''t matter much if I can''t get out." Although Chen Xin is still shoveling snow, his attitude is very indifferent.


    Qin LAN can''t help frowning when she hears Chen Xin''s answer. As Chen Xin''s ex girlfriend, she realizes that Chen Xin''s state is not right.


    Just as she was about to say something to Chen Xin, the young special police officer who helped shovel the snow suddenly asked, "sister LAN, brother Chen, how is the snow black? At first, I thought it was just a layer of dirt on my face. Why is the snow so dirty under me? "


    Looking at the snow in front of him, the young special police officer asked Qin LAN and Chen Xin.


    "Look up at the sky." Chen Xin didn''t bother to explain, he just raised his hand and pointed to the sky.


    The young SWAT looked up and saw nothing but darkness.


    Looking at the puzzled look on the face of the young special police, Qin LAN couldn''t see it, so he explained to him: "ah Xin means that the dust in the sky is so thick now, even the sun is covered, even if it snows, it will bring a lot of dust, so the snow will be dirty naturally."


    "So it is! Thank you, sister LAN. I get it. " The young special police officer said thank you. He didn''t say anything more. He just shoveled the snow hard.


    After three shovels, Chen Xin stopped: "OK, so many shovels, the door can be opened."


    Hearing Chen Xin say so, the other two people stop their own actions, and look at the door, they shovel about one meter of snow. Qin LAN is worried and asks, "is that enough? Xin, can''t you get out of the car like this? "


    "I don''t need to drive out today, just open the door." Chen Xin shook his head, turned and opened the door of the shelter: "bring things in."


    Qin LAN looked at Chen Xin, more and more feel that his state today is very problematic.


    But she still made a gesture to the young special police, let them go to the car with themselves, and removed the six air-conditioners they brought.


    The three moved the eight air-conditioners into Chen Xin''s shelter. Qin LAN looked at the piled up air-conditioners and asked Chen Xin, "ah Xin, do you want to move these things down?"


    Qin LAN comes to Chen Xin more often. He knows that the space under his shelter is not very large. Some of these eight air-conditioners occupy space. If they move down, they may occupy a lot of space.


    However, Chen Xin shook his head and said, "move it down, put it on it. When I want to use it back, don''t I still have to move it up?"


    "Well, there''s a trailer. It''s no trouble to drag it down." Qin LAN nodded slightly. Without saying much, she and the young special police put the air conditioner on the trailer, and dragged the trailer to the shelter behind Chen Xin.


    As soon as she enters the shelter through the corridor, Qin LAN clearly feels the difference.


    "Ah Xin, how can you..." Qin LAN took off his protective mask and gloves, reached out to feel the temperature in Chen Xin''s shelter, and looked at him in surprise: "do you turn on the heater?"


    "No, it''s just the ground source heat pump. I installed it myself." Chen Xin said, then extended his finger to the ground source heat pump that he had installed.


    Qin Lan was surprised, followed Chen Xin''s fingers to see the ground source heat pump, and asked with interest: "can I have a look?"


    "Whatever you want, just don''t move." Chen Xin shrugged his shoulders and directed the young special police to send eight air-conditioners into the storage room with him.


    Qin LAN went to the ground source heat pump, looking at the working unit and listening to the hum of the compressor, Qin LAN couldn''t help reaching for the pipe above.


    "Hiss ~!" Qin LAN quickly took back his finger, looking at the tip of his finger was a piece of hot red, not surprised: "the temperature is so high?"


    "The one you touch is a heat pipe, which is used to transmit the temperature to the next greenhouse. Of course, the temperature is high." Chen Xin''s voice came from behind. He went to Qin LAN and took a look at her hand: "it''s OK, it''s not serious. I don''t need to apply scald ointment."


    Hearing Chen Xin say so, Qin LAN quickly pulled his hand back and said: "I''m not so delicate, it''s not boiling water."


    See Qin LAN this appearance, Chen Xin also can helplessly pick an eyebrow.


    This is actually the reason why they broke up at the beginning. Chen Xin always regarded Qin LAN as a weak woman and worried about her everywhere. However, Qin LAN felt that she was not so weak. On the contrary, Chen Xin felt that he was the one who needed to be protected because of his lack of exercise.This cognitive difference leads to conflicts in their daily life, and also causes a lot of quarrels between them.


    Chen Xin thinks Qin LAN is too strong, but Qin LAN thinks Chen Xin is too male chauvinist.


    Although they love each other, they can''t make both sides accept the difference between the other and their own cognition.


    "Sit for a while and then go. Would you like a coke?" Chen Xin looks at Qin LAN. Maybe he feels that no one has been chatting with him for a long time. He takes the initiative to invite Qin LAN.


    Qin LAN takes a look at the young special police who is eating melons. Seeing that he has no objection, they follow Chen Xin to his living room.


    "Ah Xin, this is..." Seeing Chen Xin''s coke on the coffee table in front of the sofa and the game of pausing halfway, Qin Lan''s eyebrows wrinkle up, but stretch out again. She just looks at Chen Xin''s eyes and worries: "are you in a bad mood recently?"


    "No? I''m probably just short of sugar. " Chen Xin denied it. He just reached out and picked up the unfinished coke on the tea table. After a sip, he said, "I found it in an abandoned shop. It''s not much. It''s only enough to ask you two to share a can. Take a cup and pour it."


    Hearing Chen Xin''s words, the young special police officer quickly shook his head and said, "I don''t need it. Sister LAN can drink it. I don''t like coke!"


    Chen Xin looked at each other''s appearance, and didn''t say much. He just nodded, picked up a can of unopened coke and threw it to Qin LAN.

 Chapter 119

    "I''ve told you many times that coke is not for throwing!" Although she raised her hand to catch the coke thrown by Chen Xin, Qin LAN didn''t open it. She just put it back on the coffee table and sat down beside Chen Xin: "there is still a handle?"


    "In the drawer under the TV, I want to play and take it myself." Chen Xin took a look at Lan Qin, silently saved the game he was fighting, then transferred to a two person combat game.


    The young special police on one side also sat down on the sofa, but he cleverly stayed away from the sofa where Chen Xin and Qin LAN sat, and only sat on the single sofa.


    Qin LAN took out the handle from the drawer, looked at the picture on the TV and understood Chen Xin''s meaning: "this handle should be the one I gave you before, right? Or the same? "


    "Choose people, don''t say I bully you, let you choose first." Chen Xin has some feelings. In the past, among the few hobbies he and Qin LAN shared, fighting games should be the most they did.


    Soon, as in the past, the two chose their roles and began to fight with each other by rubbing the game handle.


    Maybe the game can really affect a person''s mood. Before they play a few games, they have already yelled. Even the young special police who watch them play are very engaged.


    ¡°KO£¡ You lost again. " Chen Xin looks at Qin LAN and says with a smile, "ah LAN, your technology has regressed!"


    "You think they are all like you, playing games every day!" Qin LAN doesn''t seem to care about losing the match, but she still rushes to Chen Xin.


    putting down the handle, Qin LAN picks up the coke Chen Xin gave her before, but just about to open it, she hesitates and puts it back. Instead, she picks up Chen Xin''s can and pours it into her mouth.


    Chen Xin couldn''t help frowning: "didn''t I give you a can? Why do you have to drink mine? "


    "What''s the matter? It''s not that I haven''t drunk before, and I haven''t spoken to you." Qin LAN puts on a look of indifference. She has been more intimate with Chen Xin in the past, which really doesn''t matter to her.


    However, in the eyes of the young special police nearby, she was flirting with Chen Xin, which made him feel embarrassed, as if he was a light bulb.


    Chen Xin took a look at the young special police officer and thought it was bad to leave him in the cold, so he handed him the handle in his hand: "do you want to play a game?"


    "No, no! I just want you to play. " The young special police officer quickly refused. Although he also likes playing games, and his hands are itching at this time, he still refused with great insight.


    For the young special police, if Qin LAN doesn''t have to wait to go back together, he has no other place to go in Chen Xin''s shelter. He really wants to hide in other places, so as not to get in the way of these two people.


    But Qin Lan''s eyes swept from him, and seemed to detect his embarrassment, so she said to him, "Xiao Wang, you go back first. I''ll stay and have something to say with a Xin."


    "Ah? Sister LAN, don''t you go back? How do you go back? " Young special police heard Qin Lan said she did not go back, immediately some at a loss.


    "I live in a Xin for two days. Anyway, I just have to take turns." Qin LAN, who had already made a plan, told the young special police: "and I just told a Xin about the need for ground source heat pump in the team these two days, and supervised him to make the equipment for the team."


    "This..." Young special police want to say something, but see Qin LAN throw over the threat of eyes, immediately reaction, very firm answer: "good LAN elder sister, I know."


    With that, the young special police quickly stood up: "then I''ll go first, sister LAN, you play here slowly."


    Looking at the young special police officer who was ready to leave, Chen Xin gave Qin LAN a meaningful look and said to her, "OK, ah LAN, please send him out. Remember to close the door."


    "I see. I''ll come as soon as I go." Qin LAN nodded and stood up to send the young special police out.


    Chen Xin looks at Qin LAN and the young special police leave, and can''t help touching his chin. There''s something wrong with it.


    Although Qin LAN and he are former lovers, even when they are still in contact, Qin LAN has never taken the initiative to stay at his home.


    Now suddenly showing such a move, Chen Xin doesn''t think that she wants to stay for two days to play games with herself.


    However, Chen Xin doesn''t want to study the reason why Qin LAN stayed. On the one hand, he is extremely decadent today and doesn''t want to waste his mind to think about things. On the other hand, he has enough trust in Qin LAN and believes that she won''t do any harm to himself.


    A person continues to play the game. Chen Xinshun takes a coke that Qin LAN has just drunk. He looks at the mouth of the can and can''t help laughing. Then he drinks it directly.


    As Qin Lan said, she had never drunk Chen Xin''s coke before, but at that time she would still leave a lipstick mark on the jar.


    Qin LAN saw off the young special police. She quickly went back to the living room and saw that Chen Xin was still playing games. She sat down beside him and picked up the handle again."Why stay?" Chen Xin asked this question while playing the game.


    Not willing to use his head to think about things does not mean that Chen Xin will not find out why.


    "Ah Xin, are you in a bad mood recently?" Qin LAN didn''t answer Chen Xin''s question, but asked him a new one: "you used to be like this. When you were in a bad mood or under too much pressure, you liked to play games with cola and potato chips, a dozen for a whole day, didn''t you?"


    Qin Lan''s words make Chen Xin feel embarrassed. At the same time, there is a little accident. He didn''t expect that his behavior pattern is so easy to guess, and Qin LAN can find his situation so carefully.


    "Am I that obvious?" Although he chose to be decadent today, Chen Xin still felt uncomfortable when he was exposed.


    "You used to be my boyfriend, but I can''t even tell you are in a bad mood?" Qin LAN doesn''t look at Chen Xin, but she is worried about whether her words are too intimate.


    Chen Xin didn''t care about Qin Lan''s words, but sighed helplessly and said: "I dreamt about the things before last night, and today I''m in a bad mood."


    Hearing Chen Xin say so, Qin LAN turns her eyes to the paper Chen Xin pasted on the wall. Some guess the reason why Chen Xin is in a bad mood: "ah Xin, do you miss your uncle and aunt?"


    "How could you not?" A bitter smile appeared on Chen Xin''s face.

 Chapter 120

    Chen Xin didn''t answer Qin Lan''s question because he didn''t need to answer it.


    "Uncle and aunt, have they gone back to their hometown? How are you going to get them back, ah Xin? " Qin LAN put down the game handle in her hand and put her hand on Chen Xin''s shoulder: "if you need my help, ah Xin, just say that I can do it for you."


    Qin Lan said that she would help, which Chen Xin believed, but the place she could help was very limited, but Chen Xin still said to her, "thanks a LAN, I will say something."


    Looking at Chen Xinyi''s listless appearance, Qin LAN doesn''t force Chen Xinzhen to do it. She just says to Chen Xin, "if you''re in a bad mood, find something to do. The more decadent you are, the more difficult it is to recover."


    "Yes? What do you think I should do, Alan Chen Xin looked at Qin LAN. At this time, he still didn''t want to work: "and you said you would stay for two days? I don''t have any extra bed and toiletries. Where do you sleep at night? And you didn''t bring your laundry. What do you do when you take a bath? "


    "Can''t you wear yours?" Qin Lan said a word, but then she was embarrassed.


    When they were lovers before, Qin LAN did wear Chen Xin''s clothes, but now that they have separated, it would be too embarrassing to say that again.


    In the end, Chen Xin broke the embarrassment, flattened the coke can, stood up and said, "I wanted to take a day off today, but as a result, I can''t rest. Come and help. I''ll take down the outside air conditioners you brought


    With that, Chen Xin threw away the can in his hand and walked out of the living room towards the storage room.


    Qin LAN watched Chen Xin go out, and quickly followed him.


    Two people will be an air conditioner outside the unit from the storage room carried out, put on the workbench.


    Looking at the scorched air conditioner, Qin LAN asked: "Xin, is this still useful? How do you want to dismantle it? "


    "It''s not very hot. It should still work. Take off the cover first." Chen Xin sat down, reached for a screwdriver and handed it to Qin LAN: "help screw it."


    With that, he himself took another screwdriver and began to remove the screws on the external unit of the air conditioner.


    With Qin Lan''s help, the screws on the external unit of the air conditioner were quickly removed, allowing Chen Xin to remove the shell smoothly, revealing the appearance inside.


    Although it is protected by the outer shell, it seems that the interior is not badly burned, and all kinds of parts remain intact, but they are still burned black.


    "It looks good. Everything should work." Chen Xin nodded slightly, indicating Qin LAN to continue to help remove the screw.


    It''s easier to disassemble than to install things. Even if you don''t know how to disassemble and assemble, you can still do it with your hands when you screw with a screwdriver.


    If you loosen all the screws, you will be able to remove what you can.


    With Qin Lan''s cooperation, Chen Xin quickly disassembled the air conditioner into a pile of parts.


    Chen Xin put these parts on the worktable one by one. Looking at the blackened layer above, he frowned a little, so he said to Qin LAN, "ah LAN, you need to get a basin of water. These things need to be cleaned."


    These parts are black, even if not burned out, the surface of a layer of black ash is also necessary to clean.


    Qin LAN nodded, ready to pick up the water, but did not see the basin: "Xin, where are you basin?"


    "Basin?" Chen Xin was stunned for a moment. Then he remembered that he had not used the basin for many years, so he said to Qin LAN, "ah LAN, go to the storage room and get a bigger plastic box. I don''t seem to have a basin."


    Seeing this, Qin LAN had to nod her head and didn''t say anything more. She went to the storeroom to get the plastic box.


    Looking at Qin LAN into the storage room, Chen Xin suddenly moved an idea, want to test the information state of the system, the concept of fuzzy exactly what effect.


    So I opened the system interface, looked at the display of the detachable external unit of the air conditioner, and click disassembly.


    The green light flashed in the storage room. A public dispatching machine sent by Qin LAN today was quietly decomposed into parts and appeared on the shelf, but Qin LAN didn''t feel it.


    Seeing this, Chen Xin immediately felt relieved that he would not be afraid to use the system functions in front of others. Moreover, after the overall upgrade of the refuge, he could also consider recruiting other people.


    Qin LAN didn''t find out what Chen Xin had done just now. She took out a large plastic box from the storage room and asked Chen Xin, "ah Xin, can this work? Where''s your tap? "


    "The tap is next to the water tank over there. Just let it go." Chen Xin pointed to the water tank embedded in the wall next to the storage room.


    Qin LAN pointed out the location of the water tank, Chen Xin is also ready to take some parts out of the storage room, and then make a ground source heat pump.


    However, before Chen Xin got up, Qin LAN made a surprised voice: "ah Xin, are you using hot water? You can''t waste heat like that, can you? "


    Chen Xin felt puzzled. He stood up and came to Qin LAN. He asked: "I''ve always been cold water! I drilled a well to pump groundwater, not hot water! "However, when he reached under the tap and felt the water flowing out, he was also surprised: "what''s the matter? Why is the water so hot! "


    Surprised, Chen Xin presses his hand directly on the wall of the water tank. As a result, he still feels warm. Obviously, the water in the water tank is hot at the moment.


    "What''s the matter? I''ve been pumping cold water before! " Chen Xin was puzzled.


    The water stored in his tank has always been cold water. At first, it was just ordinary tap water. Later, after upgrading, it became groundwater extracted. The water temperature has always been cold.


    Now it suddenly turned into hot water, which made him feel very confused.


    While checking the water tank and water supply system with system functions, Chen Xin is also thinking about what changes the water temperature in the water tank.


    Ground source heat pump? This is obviously impossible. Although the ground source heat pump uses water circulation, the connected pipes have valves and one-way opening, so there is no possibility of backflow.


    As for the rise of temperature, it will not make the water tank feel hot.


    "Ah Xin, what groundwater do you use? Is it a hot spring? " Qin Lan thought of a possibility at this time.


    Hearing what Qin Lan said, Chen Xin thinks it''s possible, but it doesn''t make sense.


    "That''s not right. I''ve been pumping cold water before. It can''t get hot suddenly!" Chen Xin still felt very strange. He shook his head and said, "if I had found that there was hot spring water below, I would have no need to build a ground source heat pump. I would have pumped hot water directly. There was no need to build a shallow geothermal heating system."

 Chapter 121

    "That''s not right. I''ve been pumping cold water before. It can''t get hot suddenly!" Chen Xin still felt very strange. He shook his head and said, "if I had found that there was hot spring water below, I would have no need to build a ground source heat pump. I would have pumped hot water directly. There was no need to build a shallow geothermal heating system."


    Qin LAN heard Chen Xin say so, she can only nod to agree.


    However, although agree with Chen Xin''s words, Qin LAN is still puzzled by the current situation. Why does the cold water suddenly turn into hot water?


    "Ah Xin, do you know what can suddenly change the temperature of groundwater?" Qin LAN thinks, still feel is below ground water suddenly changed temperature.


    "Changing the temperature of groundwater? That''s unless there''s a geological change that causes the groundwater layer to break, allowing the deep groundwater to penetrate into the shallow groundwater. " Chen Xin has really studied this problem and understands this knowledge: "when I wrote a novel before, I studied the relevant knowledge. Because the deep groundwater is closer to the mantle, its temperature will be higher than that of the shallow groundwater. If geological activities lead to the rupture of the interval between the groundwater layers and the upward seepage of the deep groundwater, it may affect the shallow groundwater The temperature of water is different. But I didn''t... "


    Chen Xingang was about to say that there was no geological activity, but he suddenly thought of yesterday''s earthquake.


    Qin LAN listened to his words, also naturally thought of the same thing: "is yesterday''s earthquake?"


    "It''s possible that if the earthquake affected the groundwater, there would be hot water." Chen Xin also nodded at this time, affirmed Qin Lan''s words.


    "That''s great. Xin, you have hot spring water now." Qin LAN can''t help but feel happy for Chen Xin.


    However, Chen Xin didn''t feel much about it. He just shook his head and said, "that''s what hot spring water is all about, and how long this hot water can last is still unknown. Although geological activities may cause the deep groundwater to gush to the shallow surface or infiltrate into the shallow groundwater, it is also likely to be short-term and may not exist after a period of time.


    If you want to have continuous use of hot spring water, at least you need to form a stable channel below. It is possible to have continuous hot water pouring up.


    In fact, this kind of thing was quite common in the past. Suddenly, the well water became turbid, smelly and hot All these indicate that geological activities have affected the quality of groundwater, but they are generally temporary changes in nature. "


    Facing Chen Xin''s explanation, Qin LAN just looked at him and said with a sad smile after he stopped: "ah Xin, you still know a lot of things as before!"


    Chen Xin picks up her eyebrows and sees that there is enough water in the plastic box, so she turns off the tap and says to Qin LAN, "carry it over. Those parts need to be washed well."


    Qin LAN nodded and lifted the plastic box full of water with him.


    "Just put it on the ground." The plastic box itself is not heavy, but it''s still heavy when it''s full of water. Chen Xin doesn''t plan to put it on the table, just put it on the floor next to the workbench.


    After putting down the plastic box full of water, Qin LAN looks at the broken parts on the table and asks Chen Xin, "ah Xin, are these parts just thrown in and soaked?"


    "I need to brush it and clean the surface." Chen Xin took down two wire brushes from the hanging board and handed one of them to Qin LAN: "it should have been soaked with kerosene, which can effectively dissolve the dirt on the surface of these things, but now it can only be brushed slowly."


    Although the system can instantly clean these things, Qin LAN won''t find it, but Chen Xin thinks it''s OK to brush them so slowly.


    There is only one stool in front of the workbench. Chen Xin wanted to go to the bedroom to move a chair down, but Qin LAN just asked him to move aside and then sat down beside him.


    Chen Xin didn''t say anything. After he indicated to Qin Lan that there were rubber gloves on the table, he put on the gloves, picked up a burnt black part, and put the wire brush on his hand into the water to wash it.


    Qin LAN is also the same movement as him, but there is only one stool in the end, and the two people are sitting so crowded.


    "Ah Xin, you are thinner than before." Qin LAN brushes a part with the wire brush on her hand, chatting with Chen Xin.


    "It''s normal to grow and work every day, unlike in the past when you had to add a lot of sugar and heat to write a book Chen Xin naturally knows that he has lost weight.


    At least when he takes a bath every day, he can clearly see that his stomach, which was protruded due to middle age, has shrunk down again, and his abdominal muscles have become somewhat contoured.


    "Ah Xin, do you still like sugar so much? Is it painful for you to have no sweet food now? " Qin LAN can''t help but worry about Chen Xin. She has seen Chen Xin looking for food everywhere in a panic after he forgot to eat because he was too focused on writing books.


    This is also a common problem of mental workers, high-intensity mental work and concentration will consume a lot of blood sugar, but the consumption of calories is not high.


    Therefore, Chen Xinhui always wants to eat something when he is writing. He is especially hungry and likes sweet food.That''s why Qin Lan said that he lost weight. Chen Xin used to rely on high sugar and high heat food, but the sugar branch was consumed by mental work, but the heat was not consumed, so it just piled up and became fat on his stomach.


    For Qin Lan''s worry, Chen Xin just smiles and shakes his head and says, "it''s OK. Now it''s not so hard to think. It''s mainly physical work every day. Instead, the heat consumption is relatively large. It''s OK not to eat sweets."


    Listen to Chen Xin say so, Qin LAN hesitated for a moment, or took off a glove, stretched out his hand to open the clothes zipper, took out a snicker from the pocket inside the clothes, and then handed it to Chen Xin.


    "Snickers? LAN, how can you have this Chen Xin didn''t answer. He was just curious about Qin LAN.


    "I found it in a supermarket by the scavenger team before. I got it in exchange for them." Qin LAN simply explained that this snicker cost her three standard rations of the refuge.


    Although it sounds like a big gap, there''s no reason to talk about it in the end. Especially now, sweets such as chocolate are very popular, not to mention Snickers, which can be used as emergency food.


    Although Chen Xin didn''t know how Qin LAN got it, she told her it was not cheap, so she shook her head and refused: "you can keep it for yourself. I don''t lack food here, and if I want to eat sweets, I can also make maltose."


    See Chen Xin did not accept, Qin LAN is not reluctant, but she did not put the Snickers away, but put on the workbench.

 Chapter 122

    Although each part of a pile needs to be brushed, with Qin Lan''s help, the two of them quickly washed all the parts and threw them in the water.


    "Is it OK to just soak like this? Xin, don''t you add detergent? " Qin LAN looked at Chen Xin so all the parts with water bubble, concern to him again confirmed.


    Chen Xin nodded his head and answered in a positive way: "it''s a pity that there is no kerosene, otherwise kerosene is the best."


    "What are you doing now?" Taking off the gloves and putting them aside, Qin LAN looks at Chen Xin, waiting for him to speak.


    Chen Xin felt a little embarrassed when he was watched by Qin LAN. He buttoned his face with his fingers and said, "if I say continue to play games, will you beat me?"


    ¡°¡­¡­¡± Qin LAN looked at Chen Xin in silence. After a while, she said, "no, Xin, you can do whatever you want. But I still think you should find something to do. Playing games doesn''t make you happy


    Qin Lan''s words made Chen Xin smile, but he didn''t say much, just nodded and said: "in this case, ah LAN, please continue to help me to assemble the ground source heat pump. Uncle Ding asked you to send so many air-conditioning external units to replace ground source heat pump from me, right? How many do you need? "


    "Ah Xin, how many materials do you need to consume to make a ground source heat pump? How large is the heating range? " Qin LAN did not say his needs first, but asked Chen Xin about the relevant data of ground source heat pump.


    "A ground source heat pump can be made from the material removed from an air conditioner, and the effective heating range is about 100 square meters. As for the specific data, I don''t have the tools to measure it. That''s about it." Although there is a system, there is no data panel in this system, so Chen Xin doesn''t know much about the equipment he made: "the thermal efficiency of ground source heat pump is about twice that of air conditioning under the same power. According to this value, you should be able to roughly get the heating effect of a ground source heat pump. If you use it in a confined space, the effect should be good ¡£¡±


    Through Chen Xin''s explanation, Qin LAN has a general understanding of the performance of the ground source heat pump made by Chen Xin, and has a number in her mind, so she said to Chen Xin, "I''ve brought eight external air conditioners this time. If I can, I hope you can make at least six equipment. If the other equipment is made with two external air conditioners, can it improve the heating efficiency "Fruit?"


    Before coming here, the political commissar specially mentioned this issue with Qin LAN. The special police team didn''t want to say eight materials for eight equipment.


    Eight external air conditioners were replaced by six equipment, and the other two external air conditioners were Chen Xin''s labor costs. This was the result of discussion between uncle Ding and the political commissar.


    They still have some doubts about the heating effect of the ground source heat pump. Before Qin LAN came, the political commissar specially told her to ask more information about the performance of the ground source heat pump from Chen Xin, so as to understand the specific heating effect of the ground source heat pump as much as possible.


    However, when Qin LAN entered Chen Xin''s refuge, she had no doubt about it. Although Chen Xin''s refuge is only a private one, and the place is not big, at a glance, there are still two or three hundred square meters. The heat provided by such a large area of ground source heat pump equipment can keep the temperature around 20 ¡æ, and the effect is very good.


    "Two? Do you mean parallel equipment can improve the heating effect of single equipment? " As soon as Qin Lan said, Chen Xin understood her meaning, nodded and said, "of course, it can be done. The combination of two devices can really improve the heating effect. Do you need a high-power ground source heat pump?"


    For this question, Qin LAN of course gave a positive answer: "the area where the SWAT team is located is not small. Even if it is only for the main district heating, it also needs high-power equipment to meet the heating demand. And with high-power equipment, we can use pipes to disperse the heat to more rooms, so that more people can get heating protection. "


    "In other words, you want to use ground source heat pump equipment to make a heating system?" Chen Xin understood what Qin LAN meant.


    For the official shelter, where there is a large area heating demand, the heating effect of centralized use of multiple equipment and the heat energy provided by the equipment is better than that of separate use of separate equipment.


    If multiple devices work together, more heat can be obtained. Of course, the heating effect is better than that of a single device.


    "Xin, can you do it?" Qin LAN see Chen Xin understand their own meaning, so concerned asked.


    What she asked, of course, is not the larger ground source heat pump equipment that Chen Xin has already answered, but the heating system based on ground source heat pump equipment.


    Chen Xin thought about it for a moment, and after simply simulating the whole system in his mind, he said: "of course, it can be done, but it needs more materials and parts. High power equipment does not mean that a bunch of low-power equipment can be put together. It''s better to have matching parts.


    And if we want to do this kind of large-scale heating system, ground source heat pump equipment is not only enough, pipes, radiator, booster pump There are a lot of things I want. I haven''t made them. Maybe I need the help of professionals. "Qin Lan was not surprised by this. After all, although Chen Xin had worked in mechanical equipment in those years, his hands-on ability was really good. He could DIY the ground source heat pump equipment by himself, but he was not a professional after all. It was too high for him to make the heating system by himself.


    If it wasn''t for the novelist''s knowledge reserve, which is like a bottomless hole, and he needs to know a little bit about everything, I''m afraid Chen Xinlian can''t even say what it takes to make a heating system.


    "Professionals, ah Xin, you don''t have to worry about it. The city has done the project planning of ground source heat pump for central heating before. With experts in this field, you only need to be responsible for providing equipment." Qin LAN calms Chen Xin''s heart, which is also the research done by the political commissar and uncle Ding when they decided to do heating in the shelter area where the SWAT team is located.


    Without the support of professional theory, they dare not carry out large-scale reconstruction of the refuge.


    Ding Shuhe and political commissar also decided to use ground source heat pump equipment for central heating in the area where the special police team is located after they found relevant experts to verify the theory.


    "Since there are experts to guide me, I don''t have much to do. Just report me the requirements for the high-power equipment I need." Chen Xin heard Qin LAN say that there are experts to provide technical support, he did not say anything more, just nodded and agreed to this matter.

    However, although it is said that, the manufacturing of high-power equipment is obviously more difficult than that of ordinary equipment.


    The power of the compressor itself is a constraint. In addition, the size design of other parts is not designed for high-power equipment. If you want to manufacture high-power ground source heat pump, unless Chen Xin uses the system to help transform the parts, you still need real supporting high-power parts.


    Qin LAN certainly knows this, so she did not force Chen Xin to manufacture high-power equipment, but said to him: "since the high-power equipment is not easy to do, ah Xin, you''d better make a ground source heat pump according to one air conditioner, and make six ground source heat pumps for our special police force. As for how to use it, I''ll take it back and give it to the experts. You don''t have to worry about it. "


    "OK, since you said that, ah LAN, just do what you said." Chen Xin has no objection.


    Using the system to help transform parts also needs to cost survival. Although the cost is not much, why not save a little?


    With Qin Lan''s help, Chen Xin takes out a stack of parts from the storage room, which are just the parts of the external air conditioner he disassembled in front of Qin LAN.


    Of course, the things disassembled by the system are not as clean as the parts disassembled by hand.


    Perhaps due to the so-called fuzzy concept of information state, Qin LAN didn''t feel that there was anything wrong with these parts as new ones. He just assisted him to assemble them one by one under the guidance of Chen Xin.


    "Ah Xin, this pipe is so thin, can it work?" Qin LAN takes a copper tube and asks Chen Xin. The copper tube is only finger thick and thin. It doesn''t look like it can effectively transport heat energy.


    Chen Xin didn''t think much of it. He didn''t say that he could upgrade the system to improve the efficiency of the equipment and the diameter of the copper tube. Even the diameter of the copper tube itself was no problem.


    However, he explained to Qin LAN: "don''t worry, there is no problem with the thickness. The air conditioner uses such a thick pipe, can''t it achieve high efficiency refrigeration in summer?"


    "Is refrigeration the same as heating?" Although she knows that the working principle of GSHP is the same as that of air conditioning, she still doesn''t think the two sets of equipment are the same.


    With a smile, he took the copper tube from Qin LAN and connected it to the assembled equipment. Chen Xin said with a smile, "how can it be different? Isn''t it all about the heat? Moreover, the thermal efficiency of ground source heat pump is twice that of air conditioner. You can see the heating efficiency of this one. Don''t worry about it. "


    Qin LAN turned to look at the ground source heat pump installed here by Chen Xin, hesitated for a moment, then nodded for sure, took the opportunity to open the zipper of his coat, took off his coat: "ah Xin, I don''t think you are still a little hot if you don''t say it."


    "Who asked you to wear such thick clothes indoors?" Chen Xin took a look at the coat Qin LAN took off. It''s not surprising that it was thickened.


    Qin LAN stretched a stretch, and her considerable figure was wrapped in her thick gray sweater, which made Chen Xin look away awkwardly: "is this the sweater I sent you?"


    "Yes, ah Xin, you bought it for me with the first month''s contribution fee. It should be the first birthday present you gave me?" Qin LAN took a look at her sweater and laughed.


    "It''s been so many years in a twinkling of an eye. I didn''t expect you to wear it." Chen Xin could not help shaking his head with some emotion.


    At that time, he just quit his original job and planned to become a full-time Internet writer. Although his parents opposed this decision, Qin LAN spared no effort to support him.


    At that time, Chen Xin fell out with his parents and moved out of the house. He originally planned to rent a house by himself, but Qin LAN directly asked him to move to her.


    It is also with Qin Lan''s support that Chen Xincai has been able to persist and become an online writer.


    So after he became a full-time Internet writer and earned the first contribution, he bought this sweater for Qin LAN as her birthday present at that time.


    Qin LAN likes this sweater very much and cherishes it all the time, which is also the witness of their love.


    It''s just a pity that the two did not get together in the end, but chose to break up.


    "Yes, so many years in a flash." Qin LAN can''t help but feel some emotion, and even said: "I still remember ah Xin, you liked me very much at that time. I only wore this sweater! Why did you like to do that at that time? "


    For this problem, Chen Xin embarrassed side to face, rubbed his nose just said: "because at that time, you have a good figure ah LAN!"


    "It''s like I''m out of shape now." Hearing Chen Xin''s answer, Qin LAN smiles.


    However, she did not continue this topic, but continued to assemble the ground source heat pump with Chen Xin.


    With Qin Lan''s help, the assembly of this ground source heat pump is very smooth, much faster than when Chen Xin assembled the first one before.


    It''s just that the parts used in this ground source heat pump equipment come from the external unit of ordinary household air conditioner, while the parts of the first ground source heat pump assembled by Chen Xin come from the external unit of household central air conditioner. There is a big power gap between the two, so there is also a gap in the size of the equipment."Ah Xin, are you ready?" Qin LAN looks at what Chen Xin has assembled and confirms it to him.


    Chen Xin nodded, stretched and stood up: "the assembly is finished, but it still needs to be debugged. Check to see if there are any problems."


    "Oh, let''s put it first. Don''t worry about debugging." Qin Lan also stood up and wiped her hands with a rag.


    Busy for most of the day, she can''t help feeling a little hungry, so she asked Chen Xin, "are you hungry, ah Xin? Why don''t you eat first? "


    "Ah LAN, are you hungry? OK, let''s eat first See Qin Lan said she is really hungry, Chen Xin indifferent nodded: "you go to wash your hands, I''ll cook."


    With that, Chen Xin wiped his hands and planned to go to the storeroom to get food, but Qin LAN held him down.


    "I''ll cook today, Xin. You''ve been busy all afternoon, and you''re tired." Finish saying, wait for Chen Xin to oppose, then walk toward his storeroom.


    Chen Xin looks at Qin LAN like this, some eyebrow picking people look at her back, can''t help but hold her chest in both hands and put the second knuckle of her right index finger into her mouth.


    This is Chen Xin''s habit of thinking about some problems. Whenever he can''t figure out something, he will do it, which helps him to think.


    Biting his finger, Chen Xin fell into doubt and thought: "a LAN What are you trying to do? reunite with? It''s impossible for us... "

 Chapter 124

    Chen Xin doesn''t want to go deep into what Qin LAN wants to do. Emotionally, he believes that Qin LAN won''t harm him or have any unfavorable ideas for him.


    Under this premise, Chen Xin thinks that what Qin LAN wants to do is acceptable to him.


    In that case, why should he care too much?


    Originally, Chen Xin didn''t want to think about things very much today. He wanted to take a day off for himself. As a result, he was dragged by Qin LAN to work all afternoon. He was already very tired. If he was asked to think about things again, Chen Xin felt that he was afraid of explosion.


    So he simply gave up thinking. He just cleaned up the workbench and went to wash his hands to prepare for dinner.


    Although Qin LAN claimed that she was cooking, in fact, there was nothing to do because there was no material available.


    Chen Xin does have a lot to eat in his food storeroom, but he has no other ingredients except his own carrots, cabbage and lettuce.


    Some of them are the self heating food stored before the disaster, the shelter standard food exchanged by Qin LAN from the special police force, and two kinds of tins exchanged by Mo Qingyan for him.


    Perhaps for the sake of Chen Xinjie''s food, Qin LAN didn''t take a lot of things out of Chen Xin''s food storeroom. She just took two standard food from the shelter, a box of canned luncheon meat, a cabbage and two carrots.


    With these things back to the living room, Qin LAN saw Chen Xin lying on the sofa still playing games, did not say anything, just went to the kitchen to start cooking dinner.


    Since the materials are limited, Qin LAN doesn''t want to make any complicated dishes. She just cleans the cabbage and carrots, cuts them up with the luncheon meat, and then cooks them together.


    While cooking these things, she also heated two standard food of the shelter.


    These are the standard food she gave back to Chen Xin. In fact, it''s still very good food only in terms of nutrition and calorie supplement.


    Rice and potatoes are the main ingredients responsible for providing starch and calories as well as part of the nutrition, while mushroom and mouse meat can provide another part, and also provide a certain amount of animal protein and fat intake.


    If you ignore the fact that these things are simply cooked and only seasoned with oil and salt, they are really good for food.


    In particular, it also comes with two energy bars made of fried noodles and crushed nuts, which is enough for an adult to maintain nutrition and calories for a day.


    For children, they may eat too much.


    But the taste and taste of these foods Qin LAN can only say that under the end of the world can not be forced.


    Rice is only cooked, of course, no problem, potatoes are OK, only a little salt seasoning is not bad, even if the taste is poor, but also can make do with.


    But mushrooms and mice are only boiled in water Qin LAN doesn''t like the taste of cooked mushrooms.


    As for the fried noodles made into energy bars, this thing does not mean the fried noodles that are cooked with noodles, but directly fried flour.


    In the flour mixed with crushed nuts, add a little salt and then stir fry directly, borrow the oil from the crushed nuts to make the fried flour have a certain viscosity and not too loose, and finally use the mold to press it. This is the production process of the energy bar in the standard food of this refuge.


    It''s also because the food is for their SWAT team, so there are two energy bars in it, and there is only one energy bar in the model distributed to the general public in the shelter.


    In the official shelters, in order to save materials, only people who are engaged in manual labor or work outside can get the model with two energy bars.


    This kind of energy bar is also very simple to eat. After breaking it, add some water to it. After mixing it together, you can eat it directly. You feel that it''s not very cold. You can use hot water in your mouth.


    Seventy years ago, in the war that broke out on the peninsula between yankuo and the Federation, the ancestors of the volunteers ate this kind of food. Of course, there were no nuts in the fried noodles.


    A mouthful of fried noodles with a mouthful of snow, the fried noodles is this kind of fried flour.


    There are four energy bars in the standard food of the two refuges. After thinking about it, Qin LAN adds two of them to the cooking vegetable soup.


    With her stirring, the pot was very clear vegetable soup has become sticky, into a vegetable paste.


    She didn''t take apart the remaining two energy bars, just put them there.


    The vegetable paste is cooked quickly, and the heated food is heated quickly, giving off the aroma of food.


    Put the food on the tea table, Qin LAN knocked on Chen Xin''s leg: "have a meal, play later."


    Chen Xin Yiyan put down the game handle, stood up to wash his hands, and then came back to prepare for dinner.


    "Ah LAN, you are good at cooking! I remember you used to only cook instant noodles. " Chen Xin looked at Qin Lan''s hot food and cooked vegetables, and did not mean his praise.


    In the past, Qin LAN didn''t care about her quality of life because of her work. Moreover, the special police force itself often needs to go out on duty. The meal time is not fixed. Most of the time, what she can eat is cold takeout.Although Qin LAN looked beautiful at that time, because of the high-intensity training, her figure was also very strong, plus the temperament of female special police sniper, she seemed to be a perfect woman, but in fact her personal life was very bad.


    The house looks clean and tidy. She asks the housekeeping to clean it every week. The kitchen is spotless. She doesn''t go into the kitchen once a month


    The only thing Qin LAN could do at that time was to cook instant noodles.


    So seeing that Qin LAN can cook a pot of vegetable paste that smells good, Chen Xinzhen feels that her cooking skills have improved a lot.


    Qin LAN didn''t feel happy about Chen Xin''s praise. Instead, she raised her face and hummed, "you look down on people, don''t you? Don''t you have an intermediate chef certificate? Now you are the same, you can only make these foods, even instant noodles can''t be cooked! "


    "Yes, I''m just a cook who can''t cook instant noodles now. Thank you, Miss police officer, for your kindness in cooking for me." Chen Xin smiles indifferently. Qin Lan''s little emotion can only add her charm to him.


    Looking at Qin Lan''s face bulging, Chen Xin could hardly resist the impulse of reaching out to pinch her cheek.


    Of course, Qin LAN can see what Chen Xin wants. When they were together before, Chen Xin liked to tease her, and then pinched her face when she was not happy.


    Think of these, Qin LAN can''t help chuckling out, not angry white Chen Xin one eye: "OK, hurry to eat, will be cold."

 Chapter 125

    The food resources are limited, so there is nothing to say about this meal.


    After eating, Qin LAN helps to take the plate to the kitchen, while Chen Xin cleans the table while she washes the dishes.


    After cleaning the table, Chen Xin still holds the game handle, but Qin LAN moves her body after washing the dishes.


    Looking at Qin LAN stretching himself, Chen Xin couldn''t help but look sideways and ask, "a LAN, when did you form the habit of fitness after dinner?"


    "It''s not called fitness after meals. It''s just a little exercise to help digestion." Qin LAN while moving the body, also said to Chen Xinquan: "Xin, you should exercise, after eating a meal, the right amount of exercise can help digestion."


    "No, I want to play games!" Chen Xin simply refused.


    Qin LAN doesn''t insist on it, but she is still active, which can be regarded as the habit she formed after the end of the world.


    After all, the conditions in the official refuge are not as good as Chen Xin''s. without games to play, we can only exercise to pass the time.


    However, Qin LAN only does some stretching and shaping movements, and does not deliberately exercise her muscles. She still remembers Chen Xin''s saying that she likes girls to have muscle lines, but she doesn''t want to look like a King Kong Barbie.


    So although Qin LAN will exercise, but it is only to maintain physical fitness and core strength of the exercise, rarely deliberately to exercise their muscles, to avoid training too developed muscles.


    After some activity, Qin LAN can''t help sweating. In addition, she wears thick clothes to keep warm. She wants to take a bath after exercise.


    If she''s in the official shelter, she might have to hurry up a little bit.


    Because the water supply in the shelter is periodic. After nine o''clock in the evening, there is no running water in the shelter. Even if there is a water tank, the hot water can only be supplied until ten o''clock at most. If we don''t hurry up, we can''t finish the bath.


    So after she had the idea of taking a bath, she began to take off her clothes.


    In Qin LAN feel is a very normal move, but Chen Xin is a little surprised and asked: "a LAN, why do you take off your clothes?"


    "Take a bath, of course you have to wash when you sweat!" Qin LAN took off her sweater, unbuttoned her shirt and asked Chen Xin, "where is your bathroom, ah Xin?"


    Chen Xin saw Qin LAN as a matter of course. He could only look away, pointed to the bathroom and said, "there, there is hot water on the left side of the tap."


    "Oh, I see. I don''t have a towel. Is it OK to use yours? " Qin LAN takes a look at Chen Xin. At this time, she has even taken off her trousers. Her long, tight legs are really dazzling.


    Facing the temptation of his ex girlfriend, Chen Xin felt more and more embarrassed, so he stopped the game, got up and went to the bedroom: "I''ll get you a new one."


    Qin LAN looks at Chen Xin''s awkward figure and can''t help laughing. She feels that Chen Xin is much more shy in some aspects than before.


    Soon Chen Xin brought her a new towel and a piece of unopened soap.


    Handed the towel and soap to Qin Lan''s hand, facing the appearance that she had taken off only a vest, Chen Xin turned his face to one side and said: "there is shampoo in the bathroom."


    "It''s not like I haven''t seen it. What''s the shame?" After Chen Xin handed over things, looking at him a pair of dare not look at their own appearance, Qin LAN can not help but tease him, but also deliberately straighten the chest.


    "Come on, don''t seduce me, take a bath quickly!" Seeing this, Chen Xin slaps Qin LAN on her hip and urges her to take a bath as before, while he deliberately pretends not to care and sits back on the sofa and continues to play the game.


    Touched the place that had been photographed by Chen Xin, Qin LAN just walked into the bathroom with a smile.


    Seeing Qin LAN enter the bathroom, Chen Xin takes a long breath, reaches out and touches her face, only to find that her hand has just hit Qin Lan''s ass.


    "I feel better than before." Chen Xin didn''t know what kind of mentality he was, but he instantly distinguished the difference between the present and the past.


    But he has no idea about Qin LAN, and there is no beautiful woman bathing less than 10 meters away from him. There is only one door between him and her.


    Although Chen Xin knows that if he wants to take a bath together, Qin LAN will not refuse, but he still has no such idea.


    It''s not that Chen Xin is a gentleman or doesn''t like women. When he and Qin LAN are together, they don''t have any restraint in this aspect. They are both energetic types, and they often make trouble all night on weekends.


    Just after breaking up, Chen Xin feels that their relationship is no longer what it used to be. He shouldn''t have any trouble with Qin LAN. Breaking up is breaking up.


    They all broke up, so why bother others.


    This is why he has no contact with Qin LAN before, and Qin LAN can understand Chen Xin''s idea.


    Since two people broke up, then do not become a burden on each other, to start a new life is good for both sides.However, this disaster has broken the tacit understanding between the two people, let them meet again, also let Qin LAN originally feel that he has calmed down the emotional waves.


    Listening to the sound of the water in the bathroom, Chen Xin feels a little restless when he remembers what happened when he watched Qin LAN take a bath.


    This made him a little short of breath, so he put down the game handle in his hand and planned to go to the storage room to get a bottle of water to drink. Maybe cold water can calm him down.


    When he came to the storage room, he picked up a bottle of pure water, unscrewed the cap and poured down half a bottle at a time. Only then did Chen Xin feel more calm.


    He didn''t rush to go up. Instead, he pricked up his ears to listen to the sound of the water in the bathroom. He planned to wait for Qin LAN to go up after taking a bath, so as to avoid some unnecessary embarrassment.


    Perhaps because of the style of the special police, Qin LAN didn''t wash it for a long time. About ten minutes later, Chen Xin heard the sound of water stop.


    Estimate Qin LAN should be dressed, Chen Xin this just took water back to the living room.


    However, what he didn''t want to see was a picture in front of him - Qin LAN, who was only wearing a sweater, was leaning on the sofa, with a pair of porcelain white long legs stretched out, making his eyes drift to a place he shouldn''t have seen.


    Seeing Chen Xin come in, Qin LAN asked him, "what are you waiting for?"


    "I don''t think so. We all broke up." Chen Xin swallowed saliva, difficult choice refused.


    But for Qin LAN, it''s obviously not the answer she wants to hear.


    So the tigress jumps up, grabs her prey, falls it on the sofa, and then pours on it

 Chapter 126

    Both Chen Xin and Qin LAN lost their strength after the female tiger hunted and the prey came back. The female tiger once again overpowered the prey, and the prey still ate the female tiger.


    "Ah Xin, how about we get back together?" Lying on Chen Xin''s back, Qin LAN put her head on his shoulder and asked in a quiet tone.


    "When you first broke up, now you tell me to get back together?" Chen Xin lies on the sofa and turns his head to look at Qin LAN lying on his shoulder: "if you have any purpose, just say it. You don''t need to cover it up. It''s hard for me not to doubt that you have ulterior motives when you make such a sudden break-up


    Said by Chen Xin, Qin Lan''s face suddenly blushed, "is my performance so obvious?"


    "I knew you had a purpose from the moment you left, but I didn''t want to think before." Chen Xinru said, turned over and sat up, took the water bottle on the table, and poured a large amount of saliva into his mouth to supplement the consumption of intense exercise just now.


    Qin LAN reached out and took the water bottle from the novice Chen, and then said, "ah Xin, come back to the official refuge with me! I don''t really trust you to live here alone. "


    "What''s the matter with living here? I have food and drink. Now the problem of heating has been solved. I don''t know how comfortable I was when I was a child. " Chen Xin heard Qin Lan''s words, immediately shook his head and refused: "and you are no longer my girlfriend, what identity do you want me to accompany you back?"


    In the face of Chen Xin''s refusal, Qin LAN didn''t say anything about the movement just now. Although traditionally girls would care about it, she was not a woman with a very traditional mind, otherwise she would not be a female special police officer.


    And Qin Lan also knows clearly that these reasons are meaningless to Chen Xinyong.


    "Ah Xin, you live here alone. Although the living conditions are very good, you are the only one who has no one to speak to. Don''t you really think there is a problem? Didn''t you find that your emotional breakdown was due to too much psychological pressure? " Qin LAN is concerned about Chen Xin, and this is what she is worried about.


    She had been worried about Chen Xin''s mental state before. After all, in this end of life, there are psychologists in the official shelters, and there are other people who can communicate with each other. Many people have psychological problems.


    Even the members of the SWAT team who have been strictly trained are not spared. Chen Xin lives in this kind of private shelter in the suburbs. Whether it''s activity space or the opportunity to communicate with people, he is far less likely to have psychological problems than the official shelter.


    However, Chen Xin didn''t show any problems when she came here several times before. In addition, the environment was not particularly bad at that time. Chen Xin could go out to communicate with Mo Qingyan, and Qin LAN didn''t mention it.


    And anyway, they have been breaking up for several years, and both sides are trying to avoid contact for such a long time. In fact, Qin LAN lacks concern and interference, and Chen Xin''s position and reason.


    But with the increase of communication between Chen Xin and the special police team, Qin LAN met him more often. After that, the communication and relationship between them gradually changed back to their usual appearance, and Qin Lan''s concern for Chen Xin gradually increased.


    This time, seeing Chen Xinna''s different decadence and his habit of playing games only when he is in a bad mood make Qin LAN realize that Chen Xin has psychological problems at this time, not just in a bad mood.


    As a sniper, the psychological quality of the requirements are very high, Qin Lan also read a lot of psychological books, for how to judge a person''s psychological condition, Qin Lan also know.


    With her familiarity with Chen Xin, Qin LAN can easily judge that Chen Xin''s psychological problems are caused by the lack of communication with people for a long time and excessive pressure.


    Qin LAN took the initiative to stay, but also want to help Chen Xin adjust psychological problems.


    However, it is obvious that her present appearance and what she did with Chen Xin just now are different from what she originally expected.


    As for why she wants Chen Xin to go back to the official refuge with her, it''s because Qin LAN doesn''t want Chen Xin to continue to live like this.


    "Why don''t you come to live with me, Alan?" Chen Xin looked at Qin LAN and looked her in the eyes: "the living conditions here are obviously better than the official shelters. Alan, if you want to live with me, can''t you move here to live with me? As long as I get my parents back, it''s a complete home. "


    "Ah Xin! Don''t you see what I mean? I hope you can return to social life. You are not Robinson. You don''t have to live alone in the wilderness Qin LAN grabs Chen Xin''s arm and persuades him.


    In Qin Lan''s opinion, Chen Xin''s living alone in the wild is no better than living together in the official refuge.


    "It''s like this time, if we don''t come, you''re alone in the shelter, and the door is snowed, don''t you want to be trapped in it?" Qin LAN hopes that Chen Xin can listen to her persuasion, and takes the case of snow sealing the door as an example: "if you are in the official shelter, although the conditions are really poor, you don''t have to worry about these things, and you don''t have to bear so much pressure!"At this point, Qin LAN is also afraid of Chen Xin and his parents. She even takes the initiative to say, "if you are worried about your uncle and aunt, I will go back to the political commissar and the team leader to help you. I will go back to your hometown with you and pick up your uncle and aunt, OK?"


    Looking at the friendship in Qin Lan''s eyes, Chen Xinming knows that she really cares about herself. She also understands that it''s true that she says she has too much psychological pressure.


    Compared with a person living in a confined space, returning to collective life can change to a larger living space, which is really helpful to their mental health.


    But for Chen Xin, this is impossible, or a road he will not choose.


    Does Chen Xin know that living in such a cramped small private shelter will bring serious psychological problems?


    Of course, he knows that Qin LAN teaches a lot of psychological knowledge. How can he not know that the depressed and cramped environment will bring serious psychological problems.


    But what can he do when he goes to the official sanctuary?


    When a technician repairs equipment or does coolie dig?


    Although Chen Xin knows a lot, he is not a professional with strong technology.


    With the support of the system in his own refuge, he can still support himself. When he goes to the official refuge, he really doesn''t know what he can do.


    And the most important thing is that Chen Xin is not sure whether his system will continue to work after he goes to the official shelter.

    "No matter what you say, I won''t go to the official shelter." Chen Xin avoids Qin Lan''s sight and still refuses.


    "Ah Xin!" Qin LAN feels a burst of trouble, Chen Xin''s stubborn character she has already understood, but she did not think that in this kind of thing, Chen Xin still does not listen to advice: "can''t you listen to my advice? You''re the only one here. If something happens, no one knows you''re dead! "


    Qin LAN words a export, immediately feel regret, this saying is too hurtful.


    However, as soon as she tried to make up for it, Chen Xin raised her hand and stopped her: "ah LAN, you don''t have to say that. I understand your good intentions, but I really don''t want to go to official shelters.


    If I am really destined to die here, it will be my grave. "


    "Ah Xin..." Qin Lan also wants to persuade, but Chen Xin obviously has no interest to continue.


    Chen Xin shook his head, stood up and picked up his clothes: "Alan, you sleep in at night. There is an electric blanket on the bed. Don''t catch cold."


    Said he himself into the bedroom, holding a quilt out, but also put the original bedroom heater out.


    Seeing Qin LAN sitting on the sofa naked, Chen Xin sighed to her: "what''s the matter? Let''s talk about it tomorrow? I''m really tired now. Can you let me sleep? "


    Chen Xin''s words make Qin LAN feel irritable, but she still controls her emotions, picks up her clothes on the sofa, and walks into Chen Xin''s bedroom with a trace of anger.


    Seeing the door slammed, Chen Xin scratched his cheek and felt helpless.


    He put on his clothes again, pulled back the sofa and put on the quilt. Then Chen Xin lay down again.


    This sofa is a model that can be towed away and turned into a single bed. Originally, Chen Xin did not expect it to play this function, but now it has really become his bed.


    Just now, although he told Qin Lan that he was going to sleep, Chen Xin didn''t feel sleepy at this time.


    "Ah ~!" With a long sigh, Chen Xin feels that he and Qin LAN are really incompatible.


    At the beginning, the reason why she broke up was the same. Qin LAN felt that she was planning for Chen Xinhao, but Chen Xin preferred to choose what she liked.


    They have different opinions. If they can''t get along with each other, they will naturally have a quarrel. If someone is willing to take a step back, maybe there won''t be so many problems.


    But no matter Chen Xin or Qin LAN, they are not the kind of character who will take a step back. If they are strong enough to be together, there will be more and more conflicts, which will eventually lead to the breakup.


    Of course, Chen Xin understands that Qin LAN is for her own good, but sometimes what people want to choose is not always for her own good.


    It''s like everyone knows that drinking too much carbonated drinks is bad for health, but who can refuse the happiness brought by fat house happy water and potato chips?


    And for Chen Xin now, it is obvious that he is the best choice to stay in his own refuge, but he can''t explain this to Qin LAN.


    Therefore, Chen Xin''s choice to refuse Qin Lan''s kindness is inevitable.


    Although in this matter, as long as Qin LAN is willing to step back and choose to move over to live with Chen Xin, all problems can be solved.


    But both Chen Xin and Qin LAN know that this is impossible, just as Chen Xin will not move to the official refuge.


    Turning over, Chen Xin can''t let go of the woman who used to be his ex girlfriend because of her emotion and infatuation with Qin Lan''s body, but he can''t give up all of this for her.


    A lot of emotions and thoughts make Chen Xin toss and turn, making him completely insomnia.


    Chen Xin outside the door can''t sleep, and Qin LAN inside the door is the same.


    Chen Xin can''t let her go. How can she let Chen Xin go?


    "Dead Chen Xin! Why don''t you listen to me once! " Qin LAN clenches her fist and hammers her pillow. She is really annoyed at Chen Xin''s stubbornness.


    If she didn''t love this man deeply, why did she send him to the door like this?


    But in spite of her annoyance, Qin LAN can''t give up her feelings for Chen Xin.


    "Come on, if you listen like that, it''s not you." Qin LAN helplessly shakes her head, sniffs the smell of Chen Xin on the pillow and bed, buries her face in the pillow full of Chen Xin, and decides to persuade Chen Xin again tomorrow.


    There was nothing to say for a night. When Qin LAN opened her eyes and woke up the next morning, she had calmed down. At the same time, she warned herself to restrain her temper and have a good talk with Chen Xin.


    However, when she got dressed and came out of the bedroom, there was no Chen Xin on the sofa in the living room.


    The folded quilt and breakfast on the tea table show that Chen Xin has been up very early.


    Go to the tea table touch breakfast, found or warm, qinlan heart flow a warm current."Remember to make breakfast for me. You have a conscience." After humming, Qin LAN just went into the bathroom to wash.


    Despite the Limited supplies, Chen Xin still put a new toothbrush and towel on the washstand.


    Looking at everything that Chen Xin is ready for, Qin Lan''s eyes also show her nostalgia. When she was with Chen Xin before, Chen Xin silently prepared everything for her and took good care of her. She didn''t need to worry about her life at all.


    But this is all in the past, Qin LAN sighed, and then picked up the toothbrush and began to wash.


    However, when Qin LAN finished washing and came out of the living room after breakfast, she still didn''t see Chen Xin.


    This makes Qin LAN very confused, at the same time, the bottom of her heart can''t help pouring out a burst of worry, quickly looking for Chen Xin''s figure.


    However, there is no storage room, no greenhouse, no power distribution room, Qin LAN searched every place of Chen Xin''s refuge, did not see his figure.


    Qin LAN is in a hurry. She runs down the corridor to the entrance of the shelter. She worries if Chen Xin has run out because she doesn''t want to see her.


    However, the gate of the shelter was closed, just like she closed yesterday. Even if she opened several doors and rushed to the outside of the shelter, she didn''t see Chen Xin''s figure, and there were no footprints on the ground for him to leave.


    "Ah Xin!" Qin LAN looks at the dark outside, shouting Chen Xin''s name, but her heart is constantly calm.


    Where did Chen Xin go? In his own shelter will be missing, this is really let Qin LAN feel strange, but also deeply puzzled.


    There are no footprints left at the door. Did Chen Xin fly away out of thin air?


    Qin LAN falls on her knees at the door of Chen Xin''s refuge. The cold wind blows through her body, making her cold and desperate.

 Chapter 128

    Chen Xin, who is deicing in a small bunker, suddenly hears someone calling his name. He pastes it on the gap where the ice has been knocked off. Looking out, he sees the door of his shelter open and Qin LAN is kneeling on the snow.


    Chen Xin is a little confused, but he still uses his flashlight to shine at Qin LAN.


    "What are you shouting? Do you want to be frozen to death when you run out in the morning without wearing protective equipment? Go in and close the door for me Chen Xin roared at Qin LAN angrily.


    It just snowed a little this morning, and the temperature was low. Qin LAN ran out without any protective equipment. The low temperature of more than - 30 ¡æ can freeze people for a short time, and even freeze to death for a longer time.


    Seeing Qin LAN kneeling in the snow, it''s no wonder that Chen Xinhui is angry.


    Hearing Chen Xin''s voice, Qin LAN quickly turns around, but is dazzled by the light of the flashlight.


    Can only a hand block in front of the eyes, squinting at the top shouting: "Xin? How did you get up there? What are you doing? "


    "I''m deicing, you get in there quickly!" Chen Xin is more and more angry. He shouts at Qin LAN through the protective mask.


    Being yelled by Chen Xin, Qin LAN feels that she is cold all over. She quickly gets up from the snow and closes the door after entering the shelter.


    After knocking off the last bit of ice, Chen Xin returns to the shelter from the passage with a hammer. Looking at Qin LAN standing in the preparation room shaking with his arms, he lifts the protective mask on his face and yells at her discontentedly: "in the morning, you have a nervous accident! Just run out like this, you''re afraid of freezing to death! "


    "I I didn''t see you when I got up just now. I thought you You''re out... " Qin LAN very uncomfortable lowered his head, feel very wronged in the heart.


    However, looking at Chen Xin''s angry appearance, she rushed up and hugged him: "I thought you were angry with me and ran out to ignore me..."


    With that, Qin Lan''s tears rolled down.


    Looking at Qin LAN crying out with her arms, Chen Xin''s original dissatisfaction has disappeared. She reaches out her hand and taps her on the back twice, and says nothing more.


    "Where have you been?" Lying in Chen Xin''s arms and crying for a while, Qin LAN quickly sorted out her feelings, but her crying looks like a pear blossom with rain, which is quite different from that of the competent female special police officer, and even looks a little weak.


    "I went to deice the vent. Now it''s so cold that the vent of the shelter will accumulate ice every day. If it''s not deicing, it will be blocked." Chen Xin explains to Qin LAN and shows her the hammer in her hand.


    Looking at the hammer on novice Chen, Qin LAN finally believed that he was removing the ice, but she was still puzzled and asked: "where did you go out from? Why didn''t I see you just after I had a look inside? "


    For this problem, Chen Xin just made a helpless expression, took Qin LAN to the corridor, pointed to the channel opened on the wall of the corridor.


    "Is this the gate?" Qin LAN is surprised to see the passage opened on the corridor. She really doesn''t notice that there is a door here.


    "There are communication antennas and vents on it. I made a shelter with reinforced concrete. Because of the weather and the humidity of the air discharged from the vents is relatively high, it''s easy to freeze and need regular de icing." Chen Xin explained, this just closed the door on the wall of corridor again.


    After Chen Xin closes the door, Qin LAN takes a closer look and finds that the door is not well built. Although it is not hidden deliberately, the light in the corridor is poor, and the position of the door happens to be in the darkest place between the two lights. If she doesn''t pay attention, she will ignore the past.


    Qin LAN and Chen Xin feel a little embarrassed when they make such a big or small oolong.


    "Go ahead and warm up. I''ll take off my protective clothing." Chen Xin touched Qin Lan''s hand and saw that her fingers were cold, so he asked her to go back to the shelter first: "by the way, heat some hot water. It''s easy for you to catch a cold when you blow cold wind."


    At this time, Qin LAN didn''t say much. She nodded her head and went back to the shelter.


    Chen Xin also returned to the preparation room, closed several doors again, took off his heavy protective clothing and mask, and then returned to the shelter.


    In the shelter, Qin LAN has put on the coat she didn''t wear before. She is guarding the electric heater that has been turned on, and the water is burning on the kitchen hearth.


    "Better?" Chen Xin took up the Snickers that Qin LAN put on the worktable yesterday and handed them to her: "this is what you brought yesterday. Let''s eat to supplement the calories first."


    Chen Xin said. He came to the kitchen again and saw that the water was almost boiling. Then he found a cup and took the water from the stove down. He poured a cup of hot water for Qin LAN and brought it to her.


    Looking at Qin Lan''s pale face, Chen Xin shakes his head, goes into the bedroom, turns out a hot water bag from the cabinet, goes back to the kitchen, fills it with hot water, and then puts it directly into Qin Lan''s clothes.


    "What is this?" Chen Xin suddenly put something in her arms, Qin Lan was stunned, but soon the heat from the hot water bag warmed her up."Hot water bag, Alain, didn''t you use it when you were a child?" Chen Xin looked at Qin LAN, stunned for a moment, and then responded: "Oh, I forgot. I don''t think you''ve seen this kind of hot water at your age. What you''ve seen should be the kind of electric heating."


    Qin LAN listens to Chen Xin and reaches into her arms to take out the hot water bag, but Chen Xin holds her down.


    "Cover more for a while, and you''ll be warm again." Chen Xin stops her, but soon takes her hand back, because the place he just pressed is Qin Lan''s chest.


    Seeing Chen Xin withdraw her hand, Qin LAN is amused by his action, but she doesn''t mind it. She just smiles and asks Chen Xin, "ah Xin, why don''t you want to go to the official shelter?"


    "This question..." Hearing Qin Lan''s question, Chen Xin thought for a moment and then replied, "just like a LAN, you will not give up the work of the special police force and move to live with me. People always insist a little. Moreover, I have invested so much effort and energy here. All living conditions are better than the official shelters. How can I be willing to move now?


    If I can''t live any more, Alan, you ask me to move now, I''ll pack my bags and go with you. There''s no nonsense. But now, apart from no one to talk to me and lack of communication with others, I''m actually living very well. How can I move if you ask me to move? "

 Chapter 129

    "But if I move here, you have no place for me to sleep!" Qin LAN looks at Chen Xin. After such a disturbance in the morning, Qin LAN seems to face up to Chen Xin''s weight in her heart.


    As for the question raised by Qin LAN, Chen Xin just said with a smile: "if you are willing to move here, of course I can let you have a place to live, and you can sleep with me in the same bed no matter what? My bed is not very big, but it''s OK for two people to sleep


    "What about your parents? Don''t you mean to bring back your uncles and aunts? " Qin LAN asked Chen Xin a key question.


    Two people also said that if Chen Xin''s parents come back, it is obviously impossible to squeeze four people.


    If you don''t say anything else, you can''t squeeze the bed.


    "For this problem, I can expand the shelter!" Chen Xin smiles.


    With the support of the system, Chen Xin does not have to worry about where other people sleep when the population increases.


    Moreover, Chen Xin inquired the system last night about whether other people would find problems after upgrading the refuge.


    The answer given by the system is that other people will default that it is the result of your labor in a way that they think is reasonable.


    In other words, if Qin LAN and Chen Xin live in the shelter and Chen Xin upgrades the shelter or other things, Qin LAN will ignore everything that happened just as she did when the system was disassembled yesterday. As for the differences caused by the upgrade, she will make up for Chen Xin''s transformation of the goods or shelter in a reasonable way.


    As for more people, the vague concept of information state after the system upgrade will affect everyone''s memory and make them "reach a consensus".


    So Chen Xin doesn''t worry about exposing his secrets when there are more people in the refuge.


    Qin LAN heard Chen Xin say so, in the heart is some heart, but she bit her lip or gave up the idea.


    It''s OK to move in with Chen Xin, but she still can''t persuade herself to resign at this time.


    "Ah LAN, you don''t have to. I can live alone." Chen Xin saw the hesitation on Qin Lan''s face, but he didn''t persuade her to move in while the iron was hot: "I''m used to living alone, but you are different, ah LAN. There''s really no need to move in. And even if you move here, what about the work of your SWAT team? Can you really resign at this time? "


    Qin LAN heard Chen Xin say so, also can only be low head.


    However, she quickly raised her head and asked Chen Xin, "ah Xin, are you really OK?"


    "It''s OK. Yesterday was just a special case. After your treatment last night, I''m ok." Chen Xin deliberately said what happened last night as a treatment and laughed at Qin LAN.


    Hearing Chen Xin say so, Qin Lan''s face can''t help reddening.


    After a moment''s silence, Qin LAN seems to have made a decision, so she said to Chen Xin, "since the treatment is effective, I''ll give you treatment every month when I come to give you something. A course of treatment every month, you need to consolidate the treatment."


    Although Qin Lan''s words sound normal, Chen Xin laughs uncontrollably.


    "Once a month? Then I need to expand the bathroom and get a bathtub. " Chen Xin touched his mouth and tried his best to make him laugh less indecently: "in this way, you can come to the hot spring. But I remember that I made an appointment with you several times before, and now I can finally get what I want."


    Chen Xin''s words let Qin Lan also recall the past, can''t help feeling: "at that time, I was too focused on my work, every time you asked me, I promised well, as a result, every time I had a temporary task, a hot spring, said for three years also didn''t bubble."


    "Now I have underground hot water here. Next time you come, I''ll fix the bathtub and we can take a hot spring." Chen Xin looks at Qin LAN and makes a promise.


    As for Chen Xin''s promise, Qin LAN couldn''t help laughing: "ah Xin, didn''t you say it might be temporary? Don''t you worry that when you finish the bathtub, the ground water is cold again? "


    "Then take a hot bath! Anyway, it''s all the same groundwater, just one cold and one hot. " Of course, hot springs are not so simple groundwater, but Chen Xin is too lazy to distinguish it.


    Now under such conditions, it''s a luxury to be able to take a bath, not to mention a hot spring.


    Qin LAN naturally doesn''t have to have a hot spring either. Nodding is the default.


    Taking the cup on the table and drinking some hot water, Qin LAN felt warm. Then she asked Chen Xin, "by the way, ah Xin, are these ground source heat pumps easy to install? Maybe you need to go to the city


    "Door to door installation?" Chen Xin was stunned for a moment. He didn''t expect Qin LAN to mention this problem.


    For the installation of ground source heat pump, Chen Xin naturally knows that it is not difficult to install the main part of the equipment. He only needs to punch holes on the ground and fix them with bolts, which is not very different from the external unit of air conditioner.


    The key problem is the pipeline. In addition to the water supply pipeline, the ground source heat pump equipment also has the underground water inlet pipeline and heat exchanger.If this part is under normal construction, underground construction should be carried out.


    This one in Chen Xin''s refuge is installed by him through the system function. Can this function be used outside the refuge?


    What he originally planned to do was to get a drill from the special police team by Qin LAN. When installing it for others, he used the drill to drill holes on the ground. After inserting the pipe, he upgraded the equipment to realize the installation of the underground pipeline.


    But now with the more convenient installation method provided by the system, do you still need the drill bit?


    Just when Chen Xin thought about these problems, the system jumped out to show its sense of existence.


    Looking at the words emerging in front of his eyes, Chen Xin nodded reassuringly, so he said to Qin LAN, "since I have sold the equipment, I will certainly be responsible for the after-sales installation."


    "Well, at that time, ah Xin, you may have to stay a few more days to ensure the normal operation of the equipment." In the first half of Qin Lan''s words, it was business, but in the second half, it suddenly changed: "you can live in my place. The shelter of the city bureau is an old-fashioned air raid shelter. There may not be so many rooms But you don''t have to worry. I''m the only one in my room. The bed is very spacious. I didn''t ask if two people were sleeping... "


    Before Qin Lan''s words were finished, Chen Xin grabbed her hand, looked at the blush on her face, put his face close to her, and whispered in her ear: "I only care about the sound insulation of your room. If you are too loud and heard by others, then you really have to move here."

 Chapter 130

    The rekindling of old love between old lovers is only an episode after all. How to survive is the theme of this doomsday.


    For Chen Xin, he no longer has to worry about how to survive.


    The emergence of hot spring water greatly improves the heat energy that can be obtained by ground source heat pump. Even if Chen Xin turns off the equipment, the temperature in the shelter can be maintained at about 13 ~ 16 ¡æ due to the influence of groundwater heating.


    If it is not necessary to maintain the temperature of the greenhouse, the ground source heat pump just made by Chen Xincai is even redundant.


    But it also gave him a new idea, that is to use the heat generated by ground source heat pump to generate electricity.


    This is not difficult to achieve in technology, just need to connect a heat recovery device on the radiator, and then use the heat to carry out heat conversion, and convert it into electric energy.


    As for the means of transforming heat energy into electricity, steam turbines commonly used in thermal power plants are enough to complete the task.


    When it comes to steam turbines, Chen Xin used to be a geek fan for a while when he was in college. In his dorm room, he used air cushion bed blowers and discarded CDs to transform a Tesla turbine that could really turn light bulbs into electricity.


    Although it has no practical significance at all, it depends entirely on the blower to drive the impeller to rotate and work, but on the whole, the thing is made, and it is not complicated to make it. Chen Xin''s computer still has drawings he used at that time.


    Tesla turbine is a turbine invented by legendary federal physicist Nicolas Tesla.


    This turbine is much more efficient than the traditional blade turbine, and Nikola Tesla once dreamed of using it to generate electricity from geothermal energy.


    Of course, although this technology looks very beautiful, it is still restricted by many conditions in practical application, so that this technology has been invented by Nikolay Tesla for more than 100 years, and its practical application is still very few.


    The main reason that restricts the popularization and application of this technology is that the inner rotor must be arranged in a compact way with disks that are thin enough and smooth enough to form a large enough rotor. Only in this way can the rotor be driven to rotate at high speed by the fluid passing through the rotor under the action of boundary layer effect.


    There is no doubt that the material for making the disc is highly required, which is not only light but also strong.


    Moreover, the bladeless turbine has a big problem, that is, the higher the load, the lower the efficiency. In order to achieve a high enough speed, the fluid flow through the rotor must be as small as possible.


    However, this is not a problem for Chen Xin.


    With the help of the system, the production of the rotor is not a problem at all, and what Chen Xin needs is only a small generator that can meet the power demand of his refuge. Neither the load nor the fluid flow is too large.


    "Xin, what are you doing?" Qin LAN watched Chen Xin continuously process a piece of metal material into a thin circular metal sheet on the workbench. She couldn''t help but feel very curious.


    "To be a turbine, I''m going to use the surplus heat of GSHP to generate electricity. I need a turbine." Hearing Qin Lan''s inquiry, Chen Xin explained to her at the same time, did not stop the work in hand.


    In fact, Chen Xin is not processing these round metal pieces himself, but in Qin Lan''s eyes, Chen Xin is processing them himself.


    With the help of the system, the metal materials are processed into thin paper like metal discs and assembled, and then the main shaft is installed in the middle, and the rotor of the bladeless turbine is finished.


    Qin LAN looks at Chen Xin''s serious work and doesn''t disturb him. She just leans on Chen Xin''s desk and watches him work quietly.


    There is a saying that the man who works hard is the most handsome. At this time, Qin Lan''s eyes to Chen Xin undoubtedly confirm this sentence.


    However, Chen Xin did not notice that Qin Lan''s eyes were full of infatuation. He just installed the assembled rotor into the volute.


    After assembling the whole turbine casing and checking that there was no problem, Chen Xin turned the rotor by hand again and confirmed that the rotor was running normally by manual turning. Then he connected the whole volute to the gearbox.


    Although the speed of Vaneless turbine is high, the torque is not big. In order to obtain enough output power, it is necessary to reduce the speed of gearbox to improve the torque of transmission shaft.


    This is not a complicated process, a set of planetary gears can solve the problem.


    As for the generator part is more simple, cutting magnetic induction line power generation principle even junior high school students understand.


    After all the parts are assembled and a generator connected to a bladeless turbine is ready, the next step is naturally installation.


    "Alan, help me carry it over." The generator is a little heavy, so Chen Xin has to ask Qin LAN to help him.


    Two people will lift the generator to the side of the ground source heat pump, put down the generator, Qin LAN curiously asked: "where should this be installed?"


    "Just connect the pipe to the condenser. When the air flow in the pipe passes through the condenser, it can absorb the heat emitted by the condenser, so as to expand the air volume and form high-speed air flow to drive the rotor of the turbine." Chen Xin explained that he opened the system interface and chose to consume the survival point to install the device.The installation of the system is much more convenient than Chen Xin''s own manual installation. He even helped him to run the line well and connect the generator to the distribution room.


    As Chen Xin adjusted the output power of the ground source heat pump and turned on the switch of the turbine, the generator started to run.


    "It''s really moving!" Looking at the turbine and generator that Chen Xin received from the condenser, Qin LAN couldn''t help but exclaim: "ah Xin, you are so powerful!"


    "People who know a little bit about machining and physics can do this. It''s nothing." Chen Xin shook his head. He didn''t feel proud of Qin Lan''s praise: "if it wasn''t for the rise of ground temperature caused by underground hot springs, the power generation capacity of this system would be enough to maintain the operation of ground source heat pump equipment.


    But now the ground temperature rises, the excess heat energy can be converted into more electric energy. As long as the power of the generator is a little higher, it should be able to maintain the power consumption here.


    Now I''m only worried that the rise of underground water temperature is temporary. When the broken underground water layer is blocked again and the low temperature drops... "


    At this point, Chen Xin could not help showing a little worried expression.


    "Ah Xin, you are too pessimistic. If you think about it better, maybe it will be permanent? You''ll have hot springs in the future. " Qin LAN smiles and encourages Chen Xin to be optimistic.

 Chapter 131

    Comforted by Qin LAN, Chen Xin doesn''t say anything more, but he plans for the worst.


    Optimism is needed, but it''s also necessary to prepare for the worst.


    In other words, if you plan for the worst, no matter what happens, you can be optimistic and positive, because the situation can not be worse.


    For Chen Xin now, the worst is


    That is, another geological movement will lead to the loss of pressure in the deep groundwater layer, and affect the shallow groundwater layer, resulting in the shallow groundwater flowing into the deep groundwater layer. Finally, there is no groundwater available here.


    Although this is a very extreme situation, geologically speaking, it is not impossible for the groundwater to be cut off due to geological activities.


    According to Chen Xin''s current situation, if the groundwater source is cut off, he will face the dilemma of water shortage again.


    Although he can exchange greenhouse vegetables for drinking water, there is a big problem here, that is, crop cultivation needs a lot of water resources.


    Moreover, the vegetables planted contain a lot of water, which will not enter the internal circulation system of the shelter for recycling.


    Therefore, if this happens, Chen Xin must find a way to get new water. As for moving, it is the final choice.


    Fortunately, there is quite a lot of snow outside now, and snowfall happens from time to time. It''s a good way to collect the melted snow and use it as water.


    However, the snow outside is very dirty, and the collected snow needs to be purified and filtered.


    In addition, upgrading the water circulation system can make the well deeper and the pump head larger, which is the result of the system upgrading. It is also a way to solve the problem once and for all.


    After thinking about what he can do to deal with it, Chen Xin becomes more comfortable with the worst that may happen. At least he has enough means to deal with it.


    This naturally made him optimistic, and he laughed at Qin LAN: "OK, the generator is installed. Next, let''s continue to do the ground source heat pump. You''ve only made one equipment for the SWAT team, and there are still five to catch up with. I don''t know if we can finish it in two days. "


    "Ah Xin, your technique is so good that you can finish it on time, and I will help you." Having seen Chen Xin''s "process" of manufacturing these mechanical equipment, Qin LAN has full confidence in Chen Xin.


    "All right, Alan, help me take the parts cleaned yesterday..." Chen Xinzheng is going to let Qin LAN dry the parts washed yesterday, but the radio in the living room suddenly rings and calls.


    Qin LAN and Chen Xinyi turn their heads and look at the living room together. They are surprised and say, "is someone calling you?"


    "Well, I''ll see what''s going on. Alan, take out the parts you cleaned yesterday and dry them with water." Chen Xin orders Qin LAN and goes to the living room.


    Picked up the short wave radio speaker, Chen Xin responded to the call, a dialogue, which let Chen Xin reaction, is another group of friends came to him to exchange ground source heat pump equipment.


    After talking to Qin LAN, Chen Xin takes the gun and goes to the entrance of the shelter. Qin Lan also puts down her work and follows Chen Xin.


    After putting on protective equipment in the preparation room, Chen Xin still goes to the small bunker through the passage and looks out through the observation port to see who is coming.


    However, the car parked in front of his shelter surprised him a little.


    It was an eight wheeled truck like a heavy truck, with eight huge tires one meter high, which made the car walk on the ground even in the thick snow.


    But it is different from trucks. Instead, it has a solid and thick compartment like an armored car, and the windows on the compartment are also shining from the inside to the outside, dimly illuminating a cloud pattern of dragon head with black background and red lines on the body in the dark.


    It doesn''t need to be carefully identified. Just these conspicuous features are enough for Chen Xin to recognize it as a refitted RV and understand who its owner is.


    "Ah LAN, don''t go out yet." After Chen Xin nodded to Qin LAN, he opened the door of the shelter.


    Qin LAN watched Chen Xin push open the gate of the refuge and go out. She was nervous, and the gun around her waist was also in her hand. She was ready to rush out at any time.


    Chen Xin walked out of the gate of the shelter and saw that the other party had not turned off the headlights, which made him blink.


    So he raised the flashlight in his hand and directly illuminated the cab of the car in front of him. He directly shook the driver''s eyes with the flashlight.


    Obviously, the other side was dazzled by Chen Xinhuang, soon turned the headlight into a low beam, and jumped out of the car.


    However, the driver''s cab of the car was obviously a little high. After the other party jumped down, his legs were directly inserted into the snow.


    "Little brother Chen, why is the snow so deep at your door?" The people who got off the car pulled their legs out of the snow, and then they came to Chen Xin with deep feet and shallow feet.Looking at the figure walking in front of him, Chen Xin said with a smile: "how deep is the snow? Don''t you feel it when you drive from downtown? And how many times have I told you not to jump out of the cab all the time and not be afraid to break your leg? "


    "I''m used to it, I''m used to it. Besides, who''s going to have the patience to climb down in such a high chassis car?" Although the figure was wearing a protective mask on his face, the voice of a playful face suddenly made people recognize his youth.


    Chen Xin and this person are naturally familiar, otherwise the other party should call him a writer rather than an acquaintance like little brother Chen.


    "Why do you come to me, Bruce? Don''t you also want to change the ground source heat pump? " Chen Xin wants to laugh every time he calls Bruce Lee, because his surname is Li: "do you still need these in your shelter?"


    "Why not?" The man immediately refuted Chen Xin''s words and said to him, "my shelter is equipped with air conditioning. It used to be OK when there was electricity, but now there is no power supply. I rely on myself to generate electricity. I can''t afford the air conditioning!"


    Hearing this, Chen Xindao was able to understand the other party''s practice, so he nodded and said, "OK, but you know the rules. Have you brought both the materials and the goods exchanged?"


    "Brother Chen, don''t you know me? When did I fail to rely on Li Yulong? " Li Yulong immediately patted himself on the chest with a confident look: "according to what you said, the two external air conditioners are made of materials. In addition, I also brought you a pickled ham and two boxes of individual rations.


    Ham I wanted to take Iberian ham, but my father didn''t let me, so I took a Jinhua ham. Don''t dislike it, brother Chen. "

 Chapter 132

    Half a year after the disaster, Li Yulong was the only one who came out with an Iberian ham.


    Li Yulong''s father was a well-known businessman in the city. At first, he started his business in catering. Later, when his business became bigger, he opened a hotel. He was also a wealthy businessman in the city.


    As the only son, Li Yulong is naturally the second rich generation who grew up pampered. Although he is a second rich generation, he does not have too many bad habits and is very straightforward.


    After graduating from University, he did not wait to die at home or inherit his family property. Instead, he opened a 4S shop in the city with the help of his Laozi. Chen Xin bought his car from him, and they met at that time.


    Although Li Yulong has the style of a rich second generation, he is not bad, and he can still talk with Chen Xin.


    In addition to being rich and fond of playing, Chen Xin, who had already met Mo Qingyan at that time, took him to several outdoor activities organized by Mo Qingyan.


    Li Yulong was also fascinated by the activity of being able to leave the city and get close to nature. He not only bought a lot of equipment from Mo Qingyan, but also became a big customer of her outdoor goods store. He bought himself the car he is driving now.


    It cost him more than 10 million to rebuild the RV with the chassis of Mercedes Benz arocs 8 ¡Á 8 truck. The interior decoration is luxurious and can accommodate 4-6 people. It can be called a mobile villa.


    However, although they can still talk, Chen Xin and he are not the same people. Even before the disaster, they just play together occasionally and don''t have much contact.


    After the doomsday disaster, Chen Xin and he only talked a few times through short wave radio, and there was not much communication.


    As for the refuge of Li Yulong''s family, I have to mention his Laozi.


    The well-to-do businessman in this city changed his career from catering industry to hotel business. At first, he was just a small hotel. However, as his business grew, many hotels were acquired and newly built. According to Chen Xin, there are at least four hotels in this city under the name of Li Yulong''s father.


    The shelter of his family was built under the most luxurious hotel of his family. It was built completely according to the specifications of the nuclear war shelter. Besides, water and electricity were supplied by independent system, and there was also a large cold storage, which could store quite a lot of food.


    When the shelter was repaired, Li Yulong once invited Chen Xin to visit it. Naturally, Chen Xin was very envious of this kind of rich man''s Doomsday castle.


    This also made Chen Xin deeply impressed by the fully functional underground blockhouse.


    Because of this, Li Yulong said that his shelter can''t afford air-conditioning now, so he wanted to exchange ground source heat pump with him. Chen Xin couldn''t believe him.


    "Brother Chen, can you let me in? It''s so cold at the gate! " Li Yulong seems to see that Chen Xin doesn''t trust him, but the rich second generation has no sense of it and naturally proposes to enter Chen Xin''s refuge.


    Chen Xin took a look at his car and secretly touched the gun in his pocket. Then he asked, "are you the only one? No one else in the car? "


    "There is also a bodyguard in the car. He is my cousin. He stays in the car to watch the car." Li Yulong has nothing to hide, and his attitude is very frank.


    Seeing his attitude, Chen Xin believed him for the time being, so he nodded and said, "OK, go in and talk."


    Then he stepped aside and motioned Li Yulong to go in.


    Without hesitation, Li Yulong walked directly into the gate of Chen Xin''s refuge. After he went in, Chen Xin followed him and closed the gate.


    "Are you there, sister Qin? Did you get back together with brother Chen? " Of course, Li Yulong knows Qin LAN, but he used to be called his sister-in-law. Chen Xin changed his name to his sister after breaking up with Qin LAN.


    Qin LAN is very evasive about this topic. She just asks Li Yulong, "I''m here for business. What are you doing here?"


    "To replace the ground source heat pump, sister Qin, you don''t know. When my father built the shelter, he installed air conditioning, and now he can''t afford electricity." Li Yulong is still just to Chen Xin''s words, a pair of his father speechless appearance.


    However, neither Chen Xin nor Qin LAN believed it.


    "Well, you don''t have to say that. We all know what your shelter is like. If you say that your home can''t afford electricity, I''m afraid no one in the city can afford it." Chen Xin directly exposed Li Yulong, and directly said: "come on, what are you doing here?"


    Chen Xin doesn''t let Li Yulong enter the shelter again, and Qin LAN just looks at Li Yulong.


    "Don''t you tell me the truth? Bruce, you want to suffer again, don''t you? " Qin LAN shows a threatening expression to Li Yulong. Although she can''t see clearly with a protective mask, her tone is enough to show her attitude.


    By Qin LAN such a threat, Li Yulong also had to raise his hand to surrender.


    "I said, sister Qin, you are as fierce as before, that is, brother Chen can stand you." Li Yulong complained, and then explained to Chen Xin, "I''m really here to replace the ground source heat pump, but it''s not for my shelter. I built a base outside myself, and now I need heating equipment."Hearing what Li Yulong said, Chen Xin couldn''t help picking his eyebrows and said in surprise, "you are idle. What are you doing? If you can''t keep a good shelter at home, what kind of base are you going to build? "


    "Hey, brother Chen, you don''t know something about it." Li Yulong showed a proud smile in front of Chen Xin, and explained: "it''s comfortable to live in my shelter, but that''s just to live in it. And just like you said, I''m really idle at home. I have nothing to do. Besides eating and sleeping every day, I almost become a pig!


    Brother Chen, you know me well. How can I live in the shelter like my father? So I''m going to find something to do


    "Find something to do? So you want a base? What''s the point? You don''t have nowhere to live Chen Xin couldn''t help laughing and thought Li Yulong was full.


    However, Li Yulong was more proud and said confidently: "brother Chen, you don''t understand. I don''t want to live in this base for myself. Although I plan to live there in the future, the purpose of building such a base is to build a trading market."


    "Exchange market?" After listening to Li Yulong''s words, Chen Xinyi immediately understood his purpose: "do you mean the black market? You want to be a dealer? "


    So far, Chen Xin''s eyes on Li Yulong are different.

 Chapter 133

    "Hey hey, brother Chen is really brother Chen. He can understand it as soon as he says it. Unlike my father, he explained to him for a long time before he understood what I wanted to do." Li Yulong gives Chen Xin a hat.


    One side of Qin LAN heard Chen Xin say black market, also understand what Li Yulong want to do, immediately frown: "the city is not already a black market?"


    There is indeed a black market in the city. Although it is formed spontaneously, it has also formed a channel for exchanging needs among various shelters.


    The city government is also aware of the existence of the black market, but it has not cracked down on it.


    In the view of the city government, this is also a channel to communicate between various shelters, so that they can exchange what they need, so they acquiesce in their existence.


    Li Yulong naturally knew this, but he said with a smile: "sister Qin, what you said is not a black market. The so-called black market in the city is just a place to exchange things among several shelters, which is far worse than the real black market. I want to create a truly professional and standardized black market, which can collect and distribute materials, buy and sell resources... "


    "What you want to do is nothing more than a trading platform that is controlled by you and can be pumped into?" Although Li Yulong boasted a lot, Chen Xin saw through his intention at a glance: "you say you want to build a base, that is to say you want to build a field under your control. You do not directly participate in the transaction, but only provide a trading platform for other people, but you can charge a handling fee."


    Being exposed by Chen Xin''s real intention, Li Yulong couldn''t help chatting: "look at what you said, brother Chen, I''m also providing convenience for you, and making a little money by the way..."


    However, Chen Xin did not pay attention to Li Yulong. Instead, he continued: "if you want to build such a trading platform, you need at least a certain amount of capital and military protection. At the same time, you need to have enough credit and prestige among the people who come to trade. If your father comes forward, it is not a problem.


    In addition to these, if you want to build such a trading platform, the key point is that you can''t let the people who come to trade continue to barter, because you can''t make money or provide services for others.


    For those who come to trade, the original black market can do it only by barter, so you must provide valuation and equivalent. That is to say, your real purpose is to master the right to issue currency. Am I right


    Chen Xin looks at Li Yulong with a bright eyes and a little admiration for the rich second generation.


    To be able to think of these things at such a time and even plan to put them into action, Li Yulong can be regarded as a figure in terms of ambition and ability.


    But on one side, Qin LAN still frowned and asked Chen Xin, "if so, this kind of trading market can''t be allowed by the municipal government. It''s completely out of the control of the state. And even if the municipal government doesn''t care, what does he take as the equivalent, why can others believe him? It''s impossible to use a bottle cap just like radioactive waste soil? "


    For Qin Lan''s question, Chen Xin guessed Li Yulong''s idea, but he still shook his head and looked at Li Yulong: "these questions, ah LAN, you have to ask yourself, but I think since you come to me, you should have someone to help you and make a plan?"


    "You are not holy without brother Chen!" Li Yulong is still joking to give Chen Xin a top hat, but also solemnly explained: "I intend to engage in this black market, or according to little brother Chen you call trading platform, want to engage in really need the permission of the government, but this part don''t worry, my father can go to the city government."


    Hearing Li Yulong''s mention of his father, Chen Xin nodded with approval: "your father''s identity and relationship suggest that the city government should have no problem. Although the city government has acquiesced in the existence of the black market for the time being, it does not mean that the city government will not manage it. It is also good for the city government to establish a formal and orderly trading market.


    It''s easy to say the equivalent. The country is still there. Money can''t be used. It''s just that we can''t buy things now. If the municipal government is involved, as long as it promises to collect money, it will not be a big problem, and it will also avoid the market credit problem of making your own equivalent. "


    "Brother Chen, you are really good. My father said that after he understood my idea." Li Yulong did not give Chen Xin a high hat this time, but sincerely admired Chen Xin.


    Hearing this, Qin LAN basically made clear the situation. She believed in the establishment of the black market to a certain extent, but she still had doubts and did not answer them: "if so, the black market can really be established, but the problem is that you are willing to make money in such a market. Your way of making money is nothing more than transaction commission, but why others What about the money? "


    Li Yulong has not explained this problem, but Chen Xin laughs.


    He looked at Li Yulong with a little deep meaning and said with a smile to Qin LAN: "this may be the reason why he came to me. As a kind of heating equipment, ground source heat pump is just needed in the current situation. If only he can provide it in the market, it will naturally attract others to trade with him.


    In short, it is enough for him to accumulate the first resources and make a reputation. With the first amount of resources, others will also know his place. As long as we get more information for our daily life, a market will naturally run. ""Hey, hey, my dad said the same thing, so brother Chen, do you think it''s..." Li Yulong looks at Chen Xin with a smile on his face.


    However, Chen Xin didn''t pay attention to him at this time. Instead, he looked at Qin LAN and asked her, "a LAN, how does the official shelter pay people to work now? Money or token? Or direct distribution of living materials? "


    "At present, the official shelters are registered according to their status, and the working hours are registered every month. People with 25 working hours can receive sufficient rations and better living materials at the end of the month." Although Qin LAN didn''t understand why Chen Xin asked her this question, she still explained to him: "ordinary people can get 30 portions of shelter food every month, which is enough to maintain a person''s survival needs for one day; people who work are the same, but there are two energy bars in their food, while people who don''t work only have one."


    "Just like I got from your SWAT team." Chen Xin nodded clearly and understood the situation: "it seems that there is a lack of conditions for this to be done."


    Since the official shelters are still issuing goods directly, it is obvious that the so-called currency, that is, the general equivalent, has not yet been formed.


    Without the appearance of the general equivalent, the market transaction can only stay in the barter mode.

 Chapter 134

    Although Li Yulong''s thoughts and intentions were confirmed, Chen Xin still did not let him into his refuge.


    He just let Li Yulong into the preparation room to sit down and talk about it with him.


    "Brother Chen, you wronged me by saying that I want the right to issue currency. The government is still there! How can this kind of thing be allowed to be private. " Although Li Yulong is ambitious, he is still sober. He doesn''t feel that he can do whatever he wants when it''s the end of the world: "what I want is only the right of coinage, not the right of issue, and it doesn''t matter whether this kind of thing exists or not. The real core interest is that with the market, there will be commercial circulation."


    Hearing this, Chen Xin couldn''t help laughing: "you can see it very clearly. Only when money flows is money. Hoarding can only be called production materials."


    However, while praising Li Yulong, Chen Xin also asked curiously, "I can understand that you want to establish commercial circulation, but now the total amount of materials in the hands of survivors is limited. Without social production, these people will sooner or later exhaust their wealth, and the market will soon dry up. How do you plan to solve this problem?"


    "Brother Chen, can you use the ground source heat pump you made to build a greenhouse for planting?" For this question, Li Yulong is just a thief. Chen Yu smiles and asks another question.


    "Growing greenhouses? Of course, the ground source heat pump can continuously output heat to maintain the planting greenhouse... " Chen Xin instinctively answered this question. In the middle of his speech, he suddenly realized: "so it is. Plantation economy exploits surplus value."


    Seeing that Chen Xin understood what he thought, Li Yulong felt embarrassed and touched his head: "Hey, brother Chen, it''s hard to hear you say that. I''m not a capitalist. I just let other people live and absorb some oil and water myself."


    Both Chen Xin and Li Yulong can understand what the other party is saying, but Qin LAN does not understand.


    She can understand what Chen Xin means by saying that the market will soon dry up. Demand determines value. What survivors need most now are all kinds of survival materials, which are not only just needed, but also the most valuable wealth.


    However, the survival materials in each survivor''s hands are limited and will be gradually consumed over time.


    It''s like everyone''s money is limited. If they can''t make more money, they will spend all the money they have.


    Qin LAN only understood what Chen Xin said about the market drying up, but still didn''t understand what he and Li Yulong said about planting greenhouses, and what Chen Xin said about plantation economy and exploitation of surplus value, which only heard in high school ideological and political class, confused Qin LAN.


    "Xin, what are you talking about?" Don''t know to ask, Qin LAN directly to Chen Xin asked his doubts.


    "Sister Qin, we didn''t say anything, but I want to build a greenhouse and I need brother Chen to provide ground source heat pump." Li Yulong explains quickly, but he is obviously fooling Qin LAN. He doesn''t want Qin LAN to understand what''s going on in the middle.


    However, Chen Xin just took a look at him and explained to Qin LAN, "ah LAN, you should understand that if there is commercial circulation in a market, there must be a continuous flow of goods for trading, right?"


    "Of course, if there is no commodity for trading, there will be no commercial circulation. I still understand that." Qin LAN nodded to show understanding.


    Seeing that Chen Xin begins to explain to Qin LAN, Li Yulong''s face is a little ugly, but he still holds back his desire to say something, just coldly watching Chen Xin explain his intention to Qin LAN.


    "Alan, since you can understand this, you can understand that in the current environment, the materials in the hands of the survivors are limited. In addition to the new material output in the hands of the authorities, other survivors can be regarded as having no production capacity at present." Naturally, Chen Xin was able to detect the change in Li Yulong''s manner, but he continued: "therefore, if you really want to build a trading platform and establish commercial circulation, the source of goods is very important.


    Now, for all the survivors, the most valuable thing is survival materials, in which the survivors need nothing more than food and heating.


    The ground source heat pump that I can do is heating equipment. After Bruce Lee obtains the ground source heat pump heating equipment from me, he can sell a survivor in need, but it''s just a one-off sale, and the profit is too little.


    So Bruce Lee, who wants to make more profits, plans to use the ground source heat pump equipment to build a greenhouse for planting, and then hire survivors to work for him, produce more food, and then sell the food to the survivors, so he can get a steady stream of benefits. "


    "But then, why do people buy his food?" Qin LAN understood Chen Xin''s explanation, but she had a new doubt: "if you work in the official shelter, you can also get food?"


    "Good question!" Chen Xin gave a compliment, just as a good speaker met the audience, he stood up to explain: "if you just grow food to sell, then there is no need for him to set up a trading platform, just sell the food.But only primitive and stupid slave owners can make money in such an inefficient way, and smart capitalists can make money in a more effective way.


    If I were Bruce Lee, I would hire a group of people to work for me, and then after planting the food, I would distribute more food to everyone than they need. This part would become surplus means of production, which could obviously be traded.


    Let the people at hand have the materials that can be used for trading, then commerce can circulate, but this is not enough, because all the means of production still only flow in a closed loop, only from me to the workers, and then from the workers to me.


    This is not profitable for me, so I need to add another trader between me and the workers, that is, other survivors. "


    Chen Xin explained to Qin LAN, and at the same time began to draw with both hands. He pointed to Li Yulong and said, "suppose Bruce Lee is another survivor. You are my worker, Alan. The food you grow every day is not only enough for you to eat, but also a lot of surplus.


    Although I generously gave you enough food for two people, the total amount of food you produced is still far greater than the reward I gave you, and the extra part is the surplus value of you exploited by me.


    At this time, I can trade the surplus value with other survivors like Bruce Lee, and exchange the food for the materials I need in his hands, so as to make more business activities in the market.


    But this is not the end, because the materials I exchange from Bruce Lee are far greater than my own survival needs. At this time, I can sell these materials to Alain.


    But it''s too inefficient. I can ask Bruce Lee to sell these materials to you directly, and let Alain take part in the market circulation of the food you need in addition to survival.


    In this way, a tripartite trading market will be formed. As long as I maintain the existence of planting greenhouses and trading platforms, I will be able to obtain new profits from afar and continuously. This is the most efficient method of exploitation. You seem to get rich rewards, but in fact you still have nothing. "

 Chapter 135

    Qin LAN stares at Chen Xin''s explanation. After understanding what Chen Xin said, she finally understands what Li Yulong is going to do, which makes her glare at Li Yulong and even want to take out the gun and kill him directly.


    "Sister Qin, don''t look at me like that! Brother Chen, what he said is too exaggerated. It''s just normal business activities. " Li Yulong was staring at Qin Lan''s eyes and his back was chilly. He quickly explained to her, "and I can help more people live by doing this! Sister Qin, you can''t say that the merchant is killed because he has made money, can you


    "Businessmen make money because they work hard. What do you do now? You can make money by lying down! " Qin LAN is a little angry. After all, Yanguo is not a western capitalist country. She will instinctively resent this kind of exploitation.


    However, before Li Yulong explains, Chen Xin pats Qin LAN on the shoulder to show her to calm down.


    "No, you are too excited, Alan." Chen Xin calmed Qin Lan''s mood for a while, and then continued: "although the essence of things is like this, as Bruce Lee said, he can really make more people live, and this is not really exploitation."


    "What do you say?" Qin LAN looks at Chen Xin and doesn''t understand why he still helps him speak after seeing through the essence of what Li Yulong wants to do.


    "It''s the end of the world. For those survivors, it''s better to have a paid job and ensure that they have enough food to live." Chen Xin, with a helpless expression on his face, pulled the corners of his mouth for a smile and then continued to explain: "although it seems that Bruce Lee doesn''t pay much, as long as the whole model works, he can continuously make profits from it, but Alan, if you don''t have such a commercial circulation created by Bruce Lee, how do you think other survivors will survive?


    They have limited food on hand. After the food is consumed, they may turn to the official shelter for help and go to the official shelter for a bite. But the question is, what if they can''t get into the official shelter?


    When the food is finished and there is no heating equipment, they can only freeze to death and starve to death.


    Although Bruce Lee is suspected of exploiting his plantation, it has to be said that more people can survive. Moreover, it is a normal business activity.


    After all, planting greenhouses is the input of Bruce Lee''s means of production. You can''t say that entrepreneurs hire workers to produce their own products. Besides paying wages, they have to share all the profits they earn with the workers, right


    Chen Xin said that, Qin LAN just reflected that he was misled by Chen Xin.


    Although what he said is true and the essence of the matter, from another point of view, Li Yulong didn''t do anything wrong. On the contrary, he made money by his own ability.


    Although on the surface, Li Yulong is really exploiting others, without his so-called "Exploitation", the whole commercial circulation cycle will not exist.


    Without the output of planting greenhouse, there will be no necessary food to maintain other people''s survival; without the trading platform, we can not exchange what we have, we can only struggle to survive with limited supplies.


    Instead of being able to obtain the materials needed to maintain their own survival, as the whole mode has been put into operation, so that they can survive better.


    And just as no one would think that the workers who work for the enterprise to produce products can also regard the profits from the enterprise''s sales of products as their own after they get their wages, Li Yulong hired these workers to cultivate land for himself, and planted greenhouses, crop seeds and other inputs belong to Li Yulong''s means of production, and the value generated by these means of production should also be included It belongs to him, not to the workers who just paid for the labor.


    The worker pays his work and gets the reward he should get, and the rest of the profit is the profit Li Yulong should get.


    This is the same even if Yanguo is not a capitalist country, otherwise there will be no such people as Er Ma Yi Wang.


    "Sure enough, it''s brother Chen. Seeing the problem is thorough!" Li Yulong quickly complimented Chen Xin, with a flattering smile on his face: "so little brother Chen, do you think this ground source heat pump can..."


    In the face of Li Yulong''s flattery, Chen Xin asked: "since I understand all this, why do you think I want to sell the ground source heat pump to you?"


    "This..." Li Yulong got stuck. He didn''t expect Chen Xin to ask this question.


    "The ground source heat pump is mine. I can build a greenhouse, and I can also cooperate with the SWAT team through Alain. I can hire people from the shelter to grow plants through official channels, and cooperate with the government to build a trading market." Chen Xin looked at Li Yulong with a bad smile: "I have ground source heat pump, but you don''t, and I also understand the principle and operation mode, so I can completely bypass you to establish such a system. What reason do you think I have to cooperate with you?"


    Hearing Chen Xin ask Li Yulong like this, Qin Lan also looks at Li Yulong with great interest and wants to see how he answers."This..." For a moment, Li Yulong really didn''t know what to say. Just as Chen Xin said, he could completely bypass Li Yulong to realize all the things that Li Yulong imagined, but Li Yulong couldn''t bypass Chen Xin.


    However, since Li Yulong was able to come up with such an idea, he still had some intelligence. After a while of thinking, he said to Chen Xin, "brother Chen, you really know how to do it. Ground source heat pump is also a resource you have, but you only have one person. If you produce source heat pump and establish a trading market, you can''t be too busy.


    You always have to work with people, don''t you? Why not cooperate with me if you cooperate with others? I have my father''s resources, and I think I''m still very capable. With my cooperation with you and my father''s resources, the efficiency of building up the whole business circulation cycle is far higher than that of brother Chen. Are you going to work alone? "


    As he said that, Li Yulong also clarified his own ideas and advantages, and convinced Chen Xin that his words were more and more smooth: "the world has entered a new era. Although this is a doomsday era, it also means that all the old things have been destroyed and new opportunities are everywhere. At this time, how can one fight alone compare with the regiment How about collaboration? So brother Chen and I should cooperate

 Chapter 136

    Li Yulong''s original purpose was not to seek cooperation with Chen Xin, but simply to exchange ground source heat pump from him.


    However, it is obvious that his wishful thinking has been fully seen through by Chen Xin, and Chen Xin''s anti general army has also made him fall into a very passive situation.


    However, although Chen Xin saw through Li Yulong''s idea and purpose, he agreed to cooperate with him after Li Yulong''s persuasion.


    Li Yulong left the materials he brought in exchange. Although Chen Xin didn''t give him the ground source heat pump equipment immediately, he agreed to cooperate. For Li Yulong, the things he brought were also worth giving away.


    After Li Yulong leaves, Chen Xin and Qin LAN return to the refuge and continue their previous work.


    "Ah Xin, why do you agree to Bruce Lee''s proposal and cooperate with him?" Qin LAN handed a wrench to Chen Xin and asked him curiously: "just like you said, you can cooperate with the special police team and bypass him to do this. Why cooperate with him?"


    Chen Xin took the spanner and screwed a part. Then he answered Qin Lan''s question: "because I''m lazy, I don''t want to directly participate in this matter. There are too many things to do to build a market, and it''s not necessary for me to work hard. "


    While answering Qin Lan''s question, Chen Xin picks up another part and installs it on the equipment being assembled.


    This is a ground source heat pump that is being assembled. Because there is no system drawing, Chen Xin can only assemble it manually by himself. All the system can provide at this time is the renovation and specification adjustment of parts, so that he can put these things together, instead of being unable to install them because of the wrong size.


    "I don''t think I''m better at running a market as a book writer than Bruce Lee, who inherits his father''s business and comes from a merchant family." Chen Xin is busy with the work at hand, still answering Qin Lan''s doubts: "as for cooperation with the special police team, do you really think the special police team is suitable for this?"


    Qin LAN is not a fool, Chen Xin said so clearly, of course, she can understand Chen Xin''s meaning.


    "It''s true that the SWAT team is not suitable to intervene in the black market. It can only cooperate with the city government." Qin LAN nodded her head and admitted Chen Xin''s statement.


    The interests involved in the black market and its impact are great, and it is not too much to say that it can affect the power pattern of the city.


    If it is the end of the collapse of the country in the film and television works, who can control such a black market, or even the whole city in disguised form.


    Now that the government has not collapsed and the control of the city government over the whole city can be guaranteed, the city government can only and must do this. The special police can step in and share some benefits.


    But if the SWAT team comes to do it, it''s really the SWAT team and the city government.


    After understanding the relationship, Qin LAN didn''t ask any more questions. Although Chen Xin can really cooperate with the municipal government and the special police team as a guarantor, if he doesn''t want to do it himself, cooperation with others is the best way.


    "Well, that''s what happened. I''m not familiar with the people of the city government. Even if I cooperate with the city government through your special police team, I belong to the weakest of the three forces. If I want to maintain my own interests, I have to spend a lot of energy. I don''t have the time and energy to do such things." Chen Xin saw Qin LAN understand their own ideas, this just told her his next plan: "my next plan is to pick up my parents back, compared with this matter, other things are not important."


    "Ah Xin, are you going to pick up your uncles and aunts? How are you going to get there? Can I help you? " Hearing Chen Xin mention to pick up his parents, Qin LAN is also concerned about it.


    "Can you get away from Swat?" Chen Xin looked up at Qin LAN and saw that she looked resolute, so he said: "theoretically speaking, with the help of the railway that is still running, taking the train to reach Anhui Province through four provinces is the most time-saving and energy-saving way, but it should be very difficult to take the train now? Not to mention bringing my parents back from Anhui Province.


    What''s more important is that my parents and their relatives are all in their original hometown in the mountains. Even if it used to be an hour''s drive in the mountains, now it may have been snowed. Even if I can take the train to Anhui Province, it''s a trouble to get my parents. "


    For what Chen Xin said, Qin LAN nodded understandably. Chen Xin is just in the suburbs. Under the snow, the roads have become a lot more difficult. We can imagine how difficult it will be if he wants to drive into his hometown.


    "So you''re going to drive by yourself? But if you drive by yourself, your car... " Qin LAN is not optimistic about Chen Xin''s SUV.


    Chen Xinli certainly nodded and said, "my car is definitely not good. If you want to drive across four provinces, at least you have to be a car like Bruce Lee."


    "So you cooperate with Bruce Lee to change his car?" Qin LAN hears Chen Xin say so, surmise his purpose with the situation."It''s good to be able to change it, but I prefer to transform one by myself. His car is a RV for enjoyment, which is not particularly suitable in this environment." Chen Xin shook his head. Of course, he was greedy for Li Yulong''s car, but he didn''t have to get it.


    Li Yulong''s RV was rebuilt with a truck chassis. When it was rebuilt, it was designed for luxury and enjoyment, so the living facilities on the RV are very comfortable, but there is no response to the extremely harsh environment.


    Now it doesn''t matter to drive in the city like this. If you want to travel a long distance, this car doesn''t seem so suitable.


    What Chen Xin wants more is to transform a similar vehicle by himself, but be prepared and protected for the harsh environment, and then drive such a car to pick up his parents.


    To achieve such a plan, Chen Xin must need a lot of resources, which he can exchange through the special police team, but obviously the efficiency will be very low, and the collection speed will be very slow.


    So this is one of the reasons why he is willing to cooperate with Li Yulong. He can collect resources through Li Yulong instead of building a market by himself, and then slowly collect resources from the market.


    Moreover, before starting to pick up his parents, Chen Xin must upgrade the shelter to accommodate more people.


    Otherwise, he brought his parents back, but there was no place for them in his shelter, which was the most embarrassing thing.

 Chapter 137

    Two days later, the truck coming out of the city stopped steadily at the gate of Chen Xin''s shelter.


    With Qin Lan''s help, a total of six ground source heat pump equipment have been manufactured, so Chen Xin and Qin LAN will go to the urban area to help with the installation of ground source heat pump.


    "Sister Qin, we are here to meet you." Two young special police officers jumped out of the truck and said hello to Qin LAN who was standing at the gate of the shelter to meet them.


    "It''s hard for you. The things are in it. Load them first." Qin LAN nodded. Without too much politeness, she ordered the two SWAT team members to carry the equipment. At the same time, she did not forget to introduce them: "this is Chen Xin. He will go back with us later. He needs to install and debug these equipment."


    After hearing Qin Lan''s introduction, they both said hello to Chen Xin, and then they began to move the equipment.


    There are not a lot of ground source heat pump equipment. Although a relatively large truck is coming, it is not easy to put the six equipment and pipe parts on the car.


    With the help of Qin LAN and Chen Xin, two SWAT members carried the equipment, and they also went back and forth for six times before they moved all the equipment to the compartment of the truck.


    "Sister Qin, there are only two seats in the car. You and Mr. Chen sit in the front. I''ll watch the equipment in the back carriage." Seeing that the equipment had been installed in the car, one of the special police team members offered to look at the equipment in the car.


    There is only one row of seats in the cab of this kind of truck. Although it''s OK to squeeze three people, four people still can''t squeeze.


    Since someone offered to go to the back of the car, Qin LAN and Chen Xin did not object, nodded and climbed into the cab, and the special police team member also went to the back of the car.


    After confirming that everyone was seated, the special police officer in charge of driving lit the engine, turned the steering wheel and drove the car downtown.


    The last time Chen Xin went out, he went to Mo Qingyan''s home after the snowstorm. It didn''t take long, but the road condition was worse than when he came out last time.


    The strong wind blew, and the goose feather snowflakes fell directly on the window glass. Everything along the road was covered with thick snow. Only the charred building debris still stood, but it was also covered with snow.


    Don''t get me wrong, it''s not the new snowfall that hit the car window, but the snow on the ground was blown up by the strong wind before it was frozen.


    Looking at these gray and black snow flakes smashing on the window, making a light crackling sound, and soon being swept aside by the rain, Chen Xin could not help but sigh: "the weather is getting worse and worse now!"


    "Yes, the wind is getting stronger and stronger. We don''t dare to drive fast when we go out on patrol, for fear of being blown sideways." The driving SWAT team members heard Chen Xin''s emotion and also took a word.


    Hearing the driver''s special police team members say so, Chen Xin asked with some doubts: "what about going out in the city? It''s impossible to say that everyone stays in the shelter, isn''t it? "


    "The people in the shelter usually don''t leave the shelter, only those special police who need to go out to perform tasks and search teams who come out to collect materials will go out often." The driver of the special police team said, the tone also hard to cover the wind and Frost: "we come out to patrol, it''s OK to have a car, at least we don''t need to blow and get cold, but it''s also hard enough, those search teams who come out to collect materials really suffer, they search the ruins in order to find something that can be used."


    Said, this special police member also could not help shaking his head.


    Qin LAN and Chen Xin feel the same when they hear this. Qin LAN is a special police officer who has to patrol. Naturally, they understand the difficulties.


    But having said that, he quickly changed the topic: "as for the traffic problems between the various shelters, it''s OK. Since the end of the day, the urban area has been digging tunnels. Now the underground passage between the Municipal Bureau and the municipal government has been opened to traffic, and the underground passage over the shopping mall has also been dug. Now the final repair is in progress. It''s very convenient It can be finished soon.


    With these underpasses, it is no longer necessary to run outside in the wind and snow to and from various shelters. The passageways connecting other shelters are also being built and opened one after another, which will soon form an underground transportation network.


    That is to say, there is no subway in this city. Otherwise, relying on the subway line, that is the ready-made transportation network. "


    Hearing this, Chen Xin couldn''t help picking his eyebrows, and his face showed a surprised expression: "has it been dug? It seems that the construction efficiency of the municipal government is very high! "


    "Well, that''s true! It''s the end of the day. A large number of workers in the shelter have nothing to do at leisure. Digging holes can be regarded as letting them have something to do to avoid accidents at leisure. " The driver of the SWAT team immediately shook his head, it seems that this deep feeling.


    Qin LAN on one side took over the conversation and interrupted: "there are too many people and too few things in the shelter now. If most people can''t move, it''s easy to breed all kinds of social problems when they are idle."


    Qin Lan''s words also have feelings. A few months ago, their SWAT team dealt with too many such things.


    Of course, Chen Xin understands the problem. If people have nothing to do, they will be idle. The reason why the street skates make trouble is that they are idle.All of them move bricks. They work from morning to night every day. They don''t have time to be idle, so they can be honest.


    They chatted and went on. Although the car was not driving fast, it didn''t take long for them to enter the city.


    Chen Xin turns his eyes to the window, and suddenly sees a light in a building by the side of the road.


    He asked Qin LAN in surprise, "is that a survivor?"


    "Well, it should be an independent survivor." Qin LAN nodded.


    "A lot of them?" Chen Xin feels a little incredible.


    Although he knew that there must be some people in the city who chose to survive without going to the official shelters, he thought that there should be few such people.


    After all, even he and his friends in the survival group were well prepared before the disaster.


    Qin LAN just shook his head: "there are a lot of such people. Before cooling down, we transferred a group of survivors from all parts of the city into the official shelters, and also received a lot of help, but there are still many people living in families or small groups in all parts of the city."


    At this point, Qin LAN couldn''t help looking at Chen Xin and saying to him, "if Bruce Lee really wants to engage in the black market, it really can, and there are still many survivors in the urban area who will go to exchange materials."


    Chen Xin nodded clearly, and at this time the car also drove into the original compound of the City Public Security Bureau.

 Chapter 138

    It''s not the first time for Chen Xin to come to the Municipal Public Security Bureau, but there is a huge difference between Chen Xin and the Municipal Public Security Bureau at this time.


    The original glass curtain wall of the office building has all been broken, only a little bit of broken traces can be seen.


    However, some maintenance seems to have been carried out on the bottom floors. At least the broken windows are blocked, and there is a faint light. It is obvious that there are still people inside.


    I just don''t know whether it''s the survivors who can''t be placed in the shelter below or the police who are still working.


    Chen Xin did not ask much, the car quickly drove into the underground garage.


    Although according to the construction standards of underground garage and civil air defense facilities, the first floor of the underground garage does not belong to the civil air defense shelter, and there is no heavy protective door installed, the fire curtain in the garage is still lowered to block the cold wind blowing in from the outside, reduce the heat loss of the shelter below, and also block the invasion of some harmful substances.


    But this also caused the vehicle to want to enter the garage, how many will have some inconvenience, must wait for these already frozen hard fire curtain to rise, can enter the garage.


    After entering the garage, the driving special police team did not continue to drive down, but drove to a parking space and parked the car in the parking space.


    Chen Xin and Qin LAN get out of the car together. The driving SWAT team has come to the rear of the car, opens the door of the car and releases another SWAT team member who has been guarding the equipment inside.


    "It''s a tough journey." From the car out of the SWAT team moving hands and feet, the body is a little stiff.


    The car is no better than the cab, and there are no proper seats. It''s really hard to hold on all the way.


    Just as the four of them got out of the car, uncle Ding, who received the news of their return, came out of the next elevator with someone.


    "Captain! Political commissar See Uncle Ding with people came over, Qin LAN and two special police team members also rushed to say hello to them.


    "Hard work all the way, have you got all the equipment back?" Ding Shutong three people return a gift, also nodded to Chen Xin at the same time, then cared about the equipment on the car.


    Qin LAN quickly nodded, affirmative answer: "a total of six ground source heat pump equipment, together with all the pipe accessories, are in the car."


    One side before staying in the carriage of the special police team members also quickly said: "six equipment intact, I watched all the way, no bump."


    Hearing Qin LAN and the special police member''s reply, Ding Shuhe and the political commissar standing next to him looked into the carriage and saw that all the six devices were in the carriage. Then a smile appeared on his face.


    "Xiao Qin, you''ve been working hard these days! Come back and have a good rest. " The commissar said cordially to Qin LAN, and soon turned his eyes to Chen Xin, smiling more and more warmly at him: "is this comrade Chen? It''s really troublesome for you. I not only want you to produce the equipment for us, but also bother you to come to the door to install it. I''m so sorry! "


    "It''s nothing. During this period, I have entrusted you with the care of the SWAT team to help load something. It''s nothing." Chen Xin was a little unfamiliar with the commissar''s kindness. After a polite response, he said nothing.


    The political commissar didn''t have any dissatisfaction because of Chen Xin''s strange response, but he still nodded with a smile: "no matter what, it''s all guests. We have to treat them well. You''d better hang out with Xiao Qin and have lunch later. We don''t have much to serve here. The only vegetables we can offer are for you. I hope you don''t mind


    "No, it''s good to have something to eat now." Chen Xin didn''t take the political commissar''s politeness seriously. He just nodded with a smile and retreated behind Qin LAN.


    On the other hand, uncle Ding has already called up his own hands and started to carry the equipment from the car.


    Seeing that they began to move things, Chen Xin reminded uncle Ding, "Uncle Ding, these pipes and equipment are numbered. Please don''t mess up the order when you move them."


    "Well, I see. I''ll get their attention." Uncle Ding nodded, turned his head to look at the people who were carrying things, and said to them, "do you hear that? Be careful not to mess up the order of things. "


    Seeing that uncle Ding finished telling others, Chen Xin nodded at ease.


    Qin Lan also said to Ding Shuhe political commissar: "Captain, political commissar, I will take ah Xin down first."


    With that, Qin LAN takes the elevator beside Chen Xinchao, and the two former special police team members also follow up and take the elevator to the inner part of the city Bureau shelter.


    While pressing the button on the elevator, Qin LAN is also introducing the situation here to Chen Xin: "the refuge of the Municipal Bureau has five floors in total. The upper three floors are underground garages, and the lower two floors are underground air raid shelters built in the last century.


    Just now we were on the ground floor, which is mainly used for parking and storing some materials. At present, we don''t need to live in it.


    The underground second floor is a formal refuge area from the beginning. Because of the civil air defense facilities and the pre disaster reinforced thermal layer, the temperature here is still appropriate. However, there are no residents on the underground second floor. The previous administrative units of the Municipal Bureau are all settled here, which are usually used for daily office work to maintain the operation of the Municipal Bureau.Starting from the third floor underground, it is the place where people really begin to live. However, the living area divided by our special police force is in the old air raid shelter on the fourth floor underground. "


    Speaking Kung Fu, the elevator has been down to the fourth floor underground.


    After Qin LAN came out of the elevator, they walked through a corridor which was obviously an elevator hall. What they walked into was a very spacious hall.


    "This is an underground air raid shelter built as a part of the third tier during the peak of the cold war. At that time, it was built according to the standards of nuclear attack prevention. It was abandoned and sealed up until this disaster." Qin LAN takes Chen Xin through the hall with the style of that era, and walks into a passage beside the hall with a number of special police members: "this hall is the central hall of the underground air raid shelter, which connects different areas of the air raid shelter. In the past, it used to act as the auditorium, but now it has become a transit station."


    "This air raid shelter is very big!" Behind Qin LAN, Chen Xin looks at the passage beside him and sighs.


    Qin LAN nodded and affirmed: "the whole underground air raid shelter has been built intermittently for more than ten years since the 1970s, and it didn''t stop until the early 1990s. The space below is very large, and all the police and their families living in the city bureau are more than enough. Our special police team is only assigned to one area, but it is almost equivalent to a complete shelter. ¡±


    Qin Lan said that she and Chen Xin had crossed the channel and entered the area where the special police team was located.

 Chapter 139

    Qin Lan said, has and Chen Xin through the channel, into the area where the special police team.


    "This is my room. The corridor outside is a little noisy, but it''s OK to close the door at night. I''m not here during the day, so it doesn''t matter much." Qin LAN let Chen Xin into her room, with a little embarrassed face.


    Chen Xin doesn''t care about this. All the way, although all the family members of the special police force live here, some children in the corridor run noisily and hang ropes to dry their clothes.


    At the end of the world, even children have sad faces, crying more than laughing, so Chen Xin doesn''t mind Qin Lan''s so-called "a little noisy".


    Before the end of his life, Chen Xin would have despised such a noisy environment. Because of his professional needs and personality, he was particularly averse to noisy environment. Otherwise, he would not have left his house in the city and had to move to the suburbs.


    But now it''s the end of the world. Everyone is crowded in the shelter. There is no way to avoid noise.


    What''s more, in recent months, Chen Xin has been stuffy in his refuge. No one can communicate with him, and no one comes to quarrel with him. After a few months, he feels that his refuge is too quiet.


    At this time, listening to all kinds of voices around, Chen Xin felt a kind of life.


    "It''s nothing. It''s good to have such conditions in the current environment." Chen Xin enters Qin Lan''s room. After she closes the door, she looks at the room.


    This room is not big, it looks like more than ten square meters, which is slightly equivalent to a university dormitory.


    There is a desk and a single bed standing upright against the wall inside. There are two chairs beside the desk, one facing the desk, one near the bed, and two double door cabinets at the foot of the bed.


    In addition, there is a folding round table and several folding stools in the room, but they are all folded up and placed against the wall, which makes the room look spacious.


    Just to Chen Xin''s surprise, there was a washstand in the corner of the room that he thought should have been eliminated by the times. On it were two basins with two towels, and next to them were four water bottles.


    Qin LAN took off her coat and hung it on the hook behind the door. At the same time, she took off the heavy military and police boots on her feet and put on a pair of slippers. At the same time, she also took a pair of slippers to Chen Xin: "change a pair of slippers, just sit on the bed."


    According to Chen Xin, it''s natural to change shoes.


    Because of going out, he changed into a pair of heavy boots. It''s OK to walk outside. When he enters the room, because of the heating, he still burns his feet.


    When Chen Xin was changing his slippers, Qin LAN picked up an open water bottle on the ground and poured some hot water into the basin. After Chen Xin changed his slippers, he said to him, "come and wash your face. Has a Xin brought a towel? No one can use mine. "


    Since he decided to stay for a few days, Chen Xin certainly didn''t make the mistake of not bringing a towel. He took out his washing bag from his backpack, opened it, took out a towel and came to the washstand. Chen Xin couldn''t help laughing: "the last time I used this washstand to wash my face, it seemed that I was in primary school."


    "Don''t be garrulous. Wash your face. I''ll take you to dinner." Qin LAN knocks Chen Xin and urges him to wash his face quickly.


    Chen Xinchong and Qin LAN smile for a while. They don''t say anything more. They just wet and dry the towel and wipe their face.


    "Wash well! What kind of face wash are you doing this? " See Chen Xin just wipe, Qin LAN immediately some dissatisfaction.


    Facing Qin Lan''s displeasure, Chen Xin said with a smile, "ah LAN, why don''t you wash your face yourself? Don''t you want to use my shampoo? So you''d better wash it first and I''ll just wipe it. Men are not so particular about it. "


    With that, Chen Xin put away the towel and sorted out the things he had brought.


    Qin LAN looked at Chen Xin, a little helpless, but also slightly with a trace of joy, did not say anything more.


    After cleaning up, the two left Qin Lan''s room, only wearing slippers to the special police canteen.


    "Just now, Alan, you said that there are five floors in the refuge of the City Council, but this is the fourth floor. What''s the purpose of the fifth floor below? Isn''t it a greenhouse? " Walking into the canteen, Chen Xin asks Qin LAN curiously.


    Qin LAN nodded and admitted: "well, the fifth floor was excavated during the reconstruction of the refuge before the disaster. There was no such floor before. The excavated space was used for planting mushrooms, raising mice and earthworms, and installing oxygen generators. But because these facilities are very important, the fifth floor can''t go down at will. "


    "Oh, yes." Chen Xin made a sudden understanding of the expression, but he had a new question: "Alan, didn''t you tell me that the official shelter is a monthly ration? How come the canteen still provides food? "


    When Chen Xin asked this question, his eyes also turned to the dining room window, where the smell of food was sending out, which made him swallow."We do take food, but we are not allowed to use fire or heat food in the shelter, in order to avoid unnecessary danger, so the food is heated and supplied in the canteen, and we eat it by ourselves during meal time." Qin LAN explained to Chen Xin that he seemed to be afraid of Chen Xin''s misunderstanding and added: "it''s not that the government departments have extra food rationing, it''s just centralized supply.


    However, some of the output of each shelter''s greenhouse can be intercepted by itself, so the canteen can also have additional dishes. As for what it is, it depends on the output of the shelter''s materials. "


    Chen Xin can''t deny to pick an eyebrow, didn''t say much, just followed Qin LAN to the dining room window.


    "Master, give me two meals." Qin LAN lowered her head and whispered a few words to the master behind the window. Master Fu nodded and handed out two pieces of heated food in the plate.


    Qin LAN handed one of them to Chen Xin. Then he and he took the plate to one side and sat down at an empty table, ready to eat.


    Chen Xin looked at the food in the plate with a surprised expression on his face.


    There was no difference in ingredients between the food and the standard food he got from the shelter. However, the master of the canteen here obviously reprocessed the food and it looked delicious. Besides, a side dish with mushroom and mouse meat made the food look more attractive.


    Feeling a little hungry, Chen Xin didn''t hesitate any more. He picked up the chopsticks and began to eat.

 Chapter 140

    When Chen Xin and Qin LAN are having dinner together, Ding Shu and political commissar also appear in the canteen.


    They noticed Chen Xin and Qin LAN and came over together.


    "Xiao Qin, Comrade Chen, are you eating?" Commissar to two people very cordial smile said hello: "can I sit here?"


    "There''s no one here. Political commissar, please sit down." Qin LAN quickly greets the political commissar and sits down, while Chen Xin nods to say hello.


    The commissar sat down with Chen Xin and Qin LAN. Of course, it was Chen Xin who said this, while Ding Shu went to the window of the canteen to get two meals. Then he turned back and sat down.


    "Did Comrade Chen start the equipment installation in the afternoon?" Although the political commissar was very polite, he didn''t have too many extra greetings and soon turned the topic to the main topic: "I don''t know what we need to cooperate with? We need to do our best to cooperate. "


    "In terms of cooperation, where are you going to install the equipment? And how are you going to do it? " When Chen Xin heard the political commissar''s question, he was not polite: "the installation of ground source heat pump is different from other equipment. The heat exchange tube needs to be deeply buried in the ground, so it is necessary to carry out drilling operation, and at the same time, it also needs to have a suitable installation site.


    As for the pipe layout and heating arrangement, that''s what you plan for yourself. I''m only responsible for the installation, operation and commissioning of the equipment. "


    The political commissar nodded his head. Although Chen Xin was responsible for the door-to-door installation, there was neither the actual situation of the site nor the demand for the use of the ditch. He just sent a few recycled waste air-conditioning external units to Chen Xin, who brought in six ground source heat pumps after the transformation. If Chen Xin could know how to install them, it would be a complete hoax.


    However, the political commissar is not unprepared for this issue.


    What makes official shelters better than shelters for the dead is that they have so many people that they can find enough people and professionals no matter what they have to do.


    In addition, the city has made project planning for the use of shallow geothermal energy before, and has been under construction. If it is not a disaster, it may be able to use shallow geothermal energy for heating in a year and a half, so it is no problem to find a professional to do the heating pipe and equipment installation planning.


    "In this regard, we have found a professional designer to do the project planning, and the design drawings are also good. The main difference is Comrade Chen''s equipment specifications and pipe diameters on your side." The political commissar was very happy to introduce the situation to Chen Xin, and said that the drawing was in the conference room of the special police team, and Chen Xin could go to see it after eating.


    Chen Xin nodded clearly and replied positively: "since there are drawings, it''s easier to say. After dinner, go to see the drawings first."


    Hearing Chen Xin say so, naturally, the political commissar will not object.


    As they were eating, Chen Xin seemed to think of something and asked Uncle Ding, "Uncle Ding, where''s Xiao Ding? Didn''t she come to dinner? "


    "Ah Ning has a mission today. Now he is on duty outside. He will come back in the evening." Uncle Ding didn''t feel strange about Chen Xin''s involvement in Ding Ning. He just explained: "now the city bureau is short of manpower. Even my daughter is nothing special. She has to go out on duty."


    Chen Xin is not qualified to comment on whether Ding Ning needs to go out to take charge of the field. Although in his opinion, uncle Ding has no problem fighting for some preferential treatment for his daughter, Chen Xin can''t say anything about whether it''s family affairs and the internal affairs of the special police force.


    After dinner, Chen Xin followed political commissar and uncle Ding to the conference room to check the drawings, while Qin LAN went back to his room.


    Although they have a good relationship, and the political commissar also said that Qin LAN should treat Chen Xin well, it''s obvious that a female special police officer can''t always do reception work. Qin LAN still has her own task.


    Especially in the past two days, she asked for leave to live with Chen Xin. Although she had a good reason, her work was delayed a lot.


    Chen Xin didn''t think there was anything wrong with this. After following the political commissar and uncle Ding to the conference room, the political commissar quickly got the drawings for him.


    "Do you plan to install the ground source heat pump equipment on this floor, and then connect the heat exchange pipes installed on the lower floor through pipes?" Chen Xin unfolded the drawing and looked at the above pipeline layout design. He didn''t put forward any suggestions for modification, but nodded: "there''s no problem with such pipe layout, but the equipment I brought with me doesn''t have so many pipes to prepare, which requires your own piping. At the same time, there is the heater itself, which is not included in the ground source heat pump equipment, and I''m not responsible for the installation. ¡±


    "of course, we have all these things ready. As long as we have confirmed the pipe diameter of the ground source heat pump equipment you made by Comrade Xiao Chen, we can complete the pipes." The commissar made sure.


    Chen Xin didn''t say much about this, but said to them: "in this case, I need to see the actual situation of the installation site. In addition, the installation of heat exchange tubes needs drilling. I asked Alain to tell you that I need a drill bit. Don''t you know if I''m ready? "


    "Don''t worry, Comrade Chen. We''ve already prepared the drill bit. It''s used to drill wells. It''s not a problem if it can drill tens of meters deep." The political commissar made a promise and banged his chest.


    Chen Xinjian knew all about the situation, so he didn''t say anything more. He just said that he wanted to see the situation of the installation site.Of course, the political commissar would not object. He personally took Chen Xin to the place where he planned to install the computer room in the future, and also called an engineer.


    This is a specially reserved room, and the six ground source heat pump equipment delivered by Chen Xinhao are also temporarily placed here.


    Chen Xin checks the room and takes out a tape measure to measure the data.


    While busy, Chen Xin also expressed curiosity about the two huge cylindrical water tanks placed in the room: "what are these two water tanks for?"


    "This is a thermal energy storage tank, which may not be used in private shelters, but we need to use it here to collect and store the heat, and then use it for heating." The engineer explained that he seemed to have an inexplicable worship for Chen Xin.


    In the end of the world, people who can produce a ground source heat pump by hand with only waste air conditioners are really powerful for people who understand the difficulty of machining and manufacturing, and it''s not surprising that they have a feeling of worship.


    However, after listening to the engineer''s words, Chen Xin nodded and said: "this is not necessarily true. For a private shelter with such an energy storage tank, besides heating, it also means 24-hour hot water. Even if the equipment is shut down, there will be enough hot water in it for a while. "


    When Chen Xin said that, the engineers showed great interest and talked with Chen Xin about the technical problems of ground source heat pump equipment.

 Chapter 141

    At dinner time, Chen Xin, who has been busy all afternoon, comes back to Qin Lan''s room to have dinner with her.


    "What did you do this afternoon, Alain?" However, Qin LAN is not in the room, but let Chen Xin wait for a while, she came back to the room, which makes Chen Xin curious.


    "Clean up the work I''ve accumulated in the past two days." Seeing that Chen Xin was already waiting for him, Qin Lan was also a little embarrassed, but she quickly explained her work in the afternoon, but didn''t elaborate: "ah Xin, are you in a hurry? Let''s go to dinner. "


    "I haven''t been waiting long. I just came back. Let''s have dinner together." Chen Xin is not curious about what Qin LAN went to do in the afternoon. He just asks her to go to the canteen together.


    Compared with lunch, the dinner was less disturbed by the political commissar and uncle Ding. Chen Xin and Qin Lan also seemed a lot more casual and chatted about some more casual topics.


    But just as they were chatting, a special police member came to Qin LAN and said eagerly, "sister LAN, you are back! When can you go about your promise to help your friend change wine? My brothers are dying of greed! "


    "Ah! I forgot Remember! Have you got everything together? I''ll go in the evening when I get together. " Qin LAN obviously forgot about it, but she soon changed her words.


    Before Qin LAN agreed to the same group of special police team members, help them to find Mo Qingyan for wine, the result of this matter because she was in Chen Xin there for two days, she forgot.


    Fortunately, this matter itself is not a particularly urgent matter, before their group of SWAT members also did not put together to exchange things, so even if Qin LAN forgot, it will not have any impact.


    Now when it comes to this, Qin LAN just needs to help them get the wine. It doesn''t cost much. After all, Mo Qingyan''s family is very close to the city Bureau. Even in this weather, she can walk there.


    "Things have already been put together. I''ll wait for sister LAN to come back!" After hearing Qin Lan''s promise, the special police almost forgot: "since you go to change wine at night, I''ll go to your room now!"


    With that, the special police team member did not care about the meal, so he left the canteen in a hurry.


    Looking at the special police team members left, Chen Xin couldn''t help laughing: "Alan, is your special police team short of wine?"


    "It''s not that much, it''s that everyone hasn''t had a drink for months." Qin LAN helplessly explained to Chen Xin what happened before, and then continued: "I should have gone to help them change wine before, but it was delayed for two days in a Xin, so it''s now."


    "Oh! So it is At the same time, Chen Xin has a bad smile on his face.


    Seeing the bad smile on Chen Xin''s face, Qin LAN didn''t know what Chen Xin was thinking. Suddenly, her cheek flushed and she kicked him under the table.


    "I''m wrong, I''m wrong!" Chen Xin, who has been kicked by Qin LAN, quickly takes it as soon as possible. Instead of continuing to tease her, he changes the topic and asks, "ah LAN, are you going to go to longniang''s at night?"


    "Well, let''s go after dinner. Qing Yan''s is not far from the market. Let''s just walk over." Qin LAN nodded.


    Chen Xin has no objection, but while agreeing to accompany Qin LAN to find Mo Qingyan to exchange wine, Chen Xin also thinks of something new: "is there such a shortage of wine now? Even your SWAT team doesn''t have alcohol? "


    "It''s not so bad to say that there isn''t any at all, but most people haven''t drunk any more since the disaster. After all, even if there is some left before the disaster, it will be consumed in the first month or two." Although Qin LAN doesn''t drink, when she promised to help her teammates change wine, the group of people gave her a good popularization of wine.


    Hearing what Qin Lan said, Chen Xin nodded understandably. After all, the official shelters and private shelters are not the same, and everyone''s material reserves and consumption are also different.


    "According to what you said by Alan, Bruce Lee still has a bright future in the black market." Through what Qin Lan said, Chen Xin thinks of what Li Yulong said before about the black market, and immediately finds business opportunities: "grow some grain to make wine, and then exchange wine for resources, which is still very promising."


    As for Chen Xin''s statement, Qin LAN frowned: "can''t you do it like this? Now that there is not enough food to eat, how can there be surplus food to make wine? "


    "That''s not necessarily. For some people, you can make them eat less than one meal a day, and they will be willing to use the saved food to make wine." Chen Xin knows a lot about some people''s love for wine.


    Although Yan people are not as good as lucians to drink alcoholic antifreeze or detergent for a little alcohol, some people are willing to eat less for wine.


    Qin LAN heard Chen Xin say so, think of his teammates who want to change wine, also can''t help shaking his head, didn''t say any more.


    After dinner with Chen Xin, they go back to Qin Lan''s room to get something. Since they have decided to go to Mo Qingyan, they still need to wear protective equipment.


    However, when Chen Xin and Qin LAN return to her room, they see a paper box at the door and two SWAT members standing beside them laughing. Qin LAN can''t help shaking her head: "are you not so good? Are you still worried that I''m greedy of your things? ""Look what sister Lan said. If sister LAN can help you get wine, this box of things will be filial to you. It''s OK!" One of the special police team members is in a hurry to please Qin LAN.


    Qin LAN helplessly shook his head, sighed: "OK, put it, I and a Xin change good equipment to help you change wine, come to get it later."


    "Thank you, sister LAN! Thank you, sister LAN A member of the special police team was busy saying thank you to Qin LAN, and even asked, "sister LAN, do you want us to help you carry things out? This box is a little heavy


    "No, I''ll carry it with Alain for a while. Just wait for a drink in the evening." Chen Xin blocks the two people''s proposal before Qin LAN opens her mouth.


    Qin LAN didn''t say much about it, but after thanking them for their kindness, he and Chen Xin carried the box into the room and closed the door.


    Two SWAT team members can only turn and leave.


    In the room, Qin LAN looks at Chen Xin curiously and asks him, "ah Xin, are you worried that others will know their position?"


    "It''s necessary to be defensive. There''s so much wine in Qingyan''s place. I''m afraid someone will have a bad idea." Chen Xin nodded directly: "after all, they are the only two sisters there. If someone has a bad heart, they can''t cope with it."

 Chapter 142

    Wearing protective equipment again, Chen Xin and Qin LAN leave Qin Lan''s room carrying the paper boxes just sent by two SWAT members, ready to find Mo Qingyan to exchange wine.


    However, Qin LAN did not take Chen Xin out from the previous route, but took him through the hall, from the passage around to another elevator, which took the elevator up to the ground floor.


    "Before we came in, the entrance was specially for vehicles. This is the personnel entrance." Carrying the box and Chen Xin out of the elevator, Qin LAN is also introducing the situation here to him: "in the past, you can take the elevator directly to the ground, but now after cooling down, you can only go to the underground floor, and then go out by stairs."


    Chen Xin nodded his head, but he curiously pointed to a deep looking passageway and asked Qin LAN, "is this the underground passageway? Where does this lead to? "


    "It leads to the city government. If you go from here, you can walk quickly. As for the way to the shopping center, it''s not repaired yet, so you can''t use it. Otherwise, it will be faster to go to Qingyan''s house." Then Qin LAN pointed to the other side of the channel.


    "Is there a way to the ground over there?" Chen Xindun is curious, because even if that road leads to Mo Qingyan''s house, it will be closer, but it won''t specially open a way. If you want to go to Mo Qingyan''s house, you still have to go from the ground.


    However, Qin LAN shook her head and said, "it''s not like this, but from that road to the refuge of the shopping center, and then from the refuge there, it will be closer to Qingyan''s home. You forget that when you went to their home, you always took the bus to the shopping center."


    Qin Lan''s words let Chen Xin knock his head, said with emotion: "this is only a few months, I actually forget that the Dragon Mother''s home is closer to the shopping center."


    Hearing Chen Xin say so, Qin LAN can''t help sighing: "for many people, I''m afraid they don''t want to recall the things before the disaster?"


    Chen Xin doesn''t know how to answer Qin Lan''s exclamation. He can only carry the box with her and leave the ground from the stairs leading to the ground.


    As soon as they got to the ground, they felt the impact of the strong wind. Even if they were carrying a piece of paper box, they swayed twice before they could stand firm, and a layer of snow fell on the paper box in their hands.


    Chen Xin presses his protective mask, turns on the headlamp he specially wears, wipes away the ice and snow on the surface, looks at Qin LAN and makes a forward gesture to her.


    Qin LAN nodded, did not speak, just raised his hand than an OK gesture, then motioned Chen Xin forward.


    Two people stepped on the thick snow, one foot deep, one foot shallow forward.


    Because of the strong wind and the fact that Chen Xin didn''t have a portable radio, they didn''t speak. They just communicated with each other through gestures.


    However, with Chen Xin''s headlights, you can light up the surroundings without the risk of getting lost.


    Mo Qingyan''s home is not far from the shelter of the City Council. Although it is difficult to walk in the snow, they still carry paper boxes, but they still arrive at Mo Qingyan''s home half an hour later.


    "Ah LAN? A Xin? How did you two come all of a sudden? " After Chen Xin and Qin LAN take off their face masks, Mo Qingyan shows great surprise.


    "I came to the city to help the SWAT team install the ground source heat pump. A LAN''s colleagues asked her to change the wine, so I came with them." Chen Xin explains to Mo Qingyan why he is here, and then pushes the box carried by himself and Qin LAN to Mo Qingyan.


    Qin LAN takes out a tactical knife from her body, and cuts open the box while saying to Mo Qingyan: "the people in the team want to drink, so they gather these things. I don''t know what they gather. Look at it, Qingyan. Just give me two bottles of wine to send them back."


    At this time, Mo Qingyan finds out what''s going on, so she squats down and looks at what''s in the box Qin LAN opened.


    "Energy bars, standard rations It''s basically these things. They should have brought their extra rations. " Qin LAN took a look at the things in the box and made a judgment soon.


    Even the members of the special police team do not have much material to exchange in this end of life. These rations should be saved from their own mouths.


    This can be seen from the fact that there are too many energy bars in the box. They should have dug out all the energy bars in their ration and added a few standard rations to make up such a box.


    Looking at this box of things, Mo Qingyan is a little sad, but after counting the number, she says to Qin LAN, "these things are OK. What kind of wine do your teammates like to drink, ah LAN? I have a lot of foreign wine here. The stronger ones are vodka and whisky. Why don''t I give you a bottle of No, two bottles of red


    Hearing Mo Qingyan''s change of tongue, Qin LAN shook her head and said, "a bottle is OK. Anyway, whiskey needs to be mixed with water. A bottle of wine is enough for them. I don''t need to give them another bottle in my face."


    Mo Qingyan sees Qin LAN say so, also did not insist, just nodded, let Mo Qingxin to take wine.Three people sit down in Mo Qingyan''s living room. Chen Xin then asks Mo Qingyan, "long Niang, what did you think about the ground source heat pump that I told you last time?"


    "Well, I''ve thought about it. I''d better install one. After two days, the weather will be a little better. Xiaoxin and I will remove two of the external air conditioners and send them back to ah Xin." After Chen Xin told her about it last time, Mo Qingyan really considered it seriously and finally decided to install a ground source heat pump for herself.


    When Chen Xin heard her saying this, he immediately nodded happily: "OK, when I go back to the old farmer, the two sets of fish and vegetable symbiosis equipment that he promised me are in place, I''ll send them to you when I finish everything."


    "I''ll trouble you." Mo Qingyan nodded, her face also showed a smile, but looking at Qin LAN sitting beside Chen Xin, she deliberately joked and said: "since it''s settled, I''ll send Xiaoxin to you later."


    Hearing this, Qin LAN suddenly feels strange and asks Mo Qingyan, "Qingyan, why do you want to send Qingxin to ah Xin?"


    "Well? Didn''t ah Xin tell you? In addition to materials, there was Xiaoxin in the price code of the equipment I exchanged with him before! " Mo Qingyan looks at Chen Xin and Qin LAN with a bad heart, and says with a deliberate sigh: "Hey, if you want to exchange with a Xin, what can you do without something good? I''ll have to make up with my sister. "


    Hearing Mo Qingyan say so, Chen Xin''s face turned green.

 Chapter 143

    To give Mo Qingxin to Chen Xin is only a joke of course.


    However, even with the explanation of Chen Xin and Mo Qingyan, Qin Lan''s face is still stinky, and Chen Xin''s eyes are horizontal. Obviously, she plans to go back to clean him up at night.


    They didn''t stay at Mo Qingyan''s house for long. After getting the wine they exchanged with Mo Qingyan and chatting about their own interests, Chen Xin and Qin LAN left Mo Qingyan''s house.


    Just before leaving, Chen Xin expressed concern about the safety of Mo Qingyan''s family.


    "Long Niang, there are only you and Xin Xiaomei. We should pay more attention to safety." Chen Xin told Mo Qingyan, pointing out the biggest security risk of her home: "usually if you don''t go out, lock the elevator underground, so that even if someone turns into your yard, as long as you lock the stairwell, the bad guys can''t come in."


    Listening to Chen Xin''s advice, although Mo Qingyan thinks that Chen Xin is a little worried, she still takes his words seriously and nods to show that she will pay attention to the problems he mentioned.


    Seeing that Mo Qingyan wrote down what she said, Chen Xin was relieved.


    They left Mo Qingyan''s home and still walked back in the wind and snow. Because of the relationship between wind and snow, even if they could not hear clearly, neither of them had the idea of chatting in this environment.


    Because the whole city has been seriously damaged, and the street lamps and other things have been damaged for a long time. Naturally, the whole city is black at this time.


    There may be survivors living in the ruins of the city, but the light they can emit is too small compared with the darkness of the whole city.


    Just like the fragile human life facing this terrible doomsday disaster, the weak flame may be extinguished by the cold wind at any time.


    Chen Xin and Mo Qingyan walk faster because they don''t need to carry anything any more. In order to avoid being lost in the dark, Chen Xin takes Qin Lan''s hand.


    Two people in Chen Xin''s body under the headlights, step on the footprints left when, quietly forward.


    It''s not easy to identify the direction in the darkness. The darkness obscures the sight, and the snow covers the road. When they come, they rely on a little bit to identify the outline of the building ruins on the roadside and the memory of the road in the past to find the right path.


    You don''t have to be so troublesome when you go back. Although the footprints left by the wind and snow have begun to blur, you can at least judge the direction and guide the path.


    However, when they could see the bright office building of the Municipal Bureau, there was a cry of "help" in the snow.


    Chen Xin and Qin LAN stop abruptly. They look at each other. Although they are blocked by a protective mask, they are still surprised in each other''s eyes.


    Chen Xin is still a little hesitant, not sure whether to go to see what''s going on, but Qin LAN has pulled out his gun and rushed to the direction of the cry.


    Seeing this, Chen Xin gritted his teeth, took out his gun from his pocket, turned off his headlight and followed him.


    In the wind and snow, the two people followed the direction of the cry, and they came to an alley. Suddenly, they saw three figures beating another figure on the ground.


    One of the three men was wearing a flashlight, so that Qin LAN and Chen Xin could see the figure of the three men and the figure on the ground.


    Just when Chen Xin and Qin LAN have rushed over, Chen Xin noticed that one of them held something up in his hand and flashed by the flashlight, which looked like a red thing.


    "Don''t move Qin LAN yelled, but the voice obviously did not penetrate the snow, or let the other party stop.


    Chen Xin saw the figure holding up the red object and still wanted to wave his weapon.


    "Bang!" Qin LAN shot.


    "Bang! Bang! Bang After a shot, there were three shots in a row, but Chen Xin noticed that although Qin LAN hit three people, none of them fell down. They even noticed Qin LAN and his arrival. The man with the flashlight had illuminated them.


    "Bang! Bang! Bang! Bang! Dang


    With four shots in a row, the heads of the three standing figures all burst into blood. Even the red weapon, which had been dropped, was hit by a bullet. It flew out and fell to one side without hurting the figure on the ground.


    Qin LAN looks back at Chen Xin gasping with a gun. Surprised by his shooting technique, he doesn''t think much about it. He runs up to check the figure on the ground.


    Chen Xin''s hands trembled and he was still immersed in the shock that he had just killed.


    He killed himself, but he still killed three people.


    Chen Xin is very clear about his achievements just now. Even though the surrounding light is not good and the flashlight is dazzling, he still knows that he has three shots in the head and one shot flies the fallen fire axe.


    Because all this in his eyes at the moment under the tactical eyepiece, are so clear.Just now, when he rushed over, Chen Xin took out his gun, but he knew how he had never fired at all. So he smashed 400 survival points and upgraded his pistol to two levels, turning it into an intelligent pistol with automatic aiming and a pair of tactical eyepieces.


    With the plug-in of automatic aiming, it''s not difficult to blow a gun''s head.


    But in the game, the first blow only brings the pleasure of killing, but in reality, the first blow only brings bloody shock.


    He killed three people.


    It is an indisputable fact that no matter who the other party is or what cruel things they have done, he personally ended three lives, or in such a cruel way as to blow his head.


    Although Chen Xin''s number of kills in the game has already exceeded five digits, in reality, he has killed the most chickens and has only seen the killing of pigs. He really understands the impact of three human lives by himself, which makes his brain blank at this time.


    Qin LAN, who has checked the scene and dealt with the wounded on the ground urgently, sees Chen Xin still standing in the snow with a gun, and runs over.


    "Ah Xin, it''s OK. It''s over!" Qin LAN can''t speak in a low voice at this time. She can only shout at Chen Xin and try to let him put down his gun.


    "I Did I kill someone? " Chen Xin lowers his arm under Qin Lan''s pressure and looks at Qin LAN. His face is unbelievable.


    "It''s OK, ah Xin. It''s just three thugs. You didn''t hit. I did." Qin LAN looks at Chen Xin and tells a little lie. She doesn''t want Chen Xin to bear these.

 Chapter 144

    Qin Lan said that he didn''t hit the target. She hit the target because of her good intentions. After all, as a special police officer and sniper, it''s not the first time for her to get blood on her hands. It''s also her job.


    However, Chen Xin is different. He is not a soldier or a policeman. He is just an Internet writer and an ordinary civilian. His hands are not stained with blood.


    It''s just that this kind of lie is meaningless to Chen Xin.


    Qin LAN may have thought that it was dark and Chen Xin didn''t see clearly what happened, but in the night vision perspective of the upgraded tactical eyepiece, everything was so clear that it couldn''t even be described as delicate.


    In addition, the tactical eyepiece also has the functions of zooming in, zooming out and focusing. Chen Xin almost watched with his own eyes as his bullets went into the heads of the three dead people, smashing them like a watermelon, taking away most of their brain contents. By the way, his skulls were broken, and his whole head collapsed like a shrunken skin pocket.


    Such a bloody and shocking scene shocked Chen Xin so much that he didn''t recover for a long time.


    Although I have seen the scenes of head bashing in various film and television works, and I have played at least a thousand different types of head bashing in my own games, it is impossible for them to show the most real head bashing scenes to the audience or players, whether it is film and television works or video games, because it is too bloody.


    So even though Chen Xin didn''t think he was short of endurance, he didn''t think he had never seen a blow out, but he was still frightened by the three rotten watermelons in a row, and his whole body was shaking.


    Fortunately, it''s not far from the Municipal Bureau. After Qin LAN called for reinforcements, a police car patrolling nearby soon came.


    The police who arrived were also surprised by the scene in front of them. They killed three people. This is not the scene in the game. In reality, I''m afraid there has never been such a bloody scene in this city except in the war years.


    But at least it''s the police. They don''t have the psychological endurance. After learning about the situation with Qin LAN, they rushed the injured and Chen Xin into the car and sent them directly to the refuge of the first people''s Hospital of the city. Only two people were left to collect the body.


    And Qin LAN is not at ease Chen Xin, also jumped on the car, followed by the hospital.


    In the car, Chen Xin''s gun is still in his hand. Qin LAN tries to let Chen Xin put down the gun, but the problem is that Chen Xin, who usually has little strength, holds the gun to death. It''s useless for anyone.


    Qin LAN is not good at grabbing, so as not to stimulate Chen Xin to let him fight with a gun. He can only close the gun insurance in his hand when Chen Xin doesn''t resist.


    Although according to the Convention, Qin LAN should drop Chen Xin''s gun at this time, considering that Chen Xin Gang has been greatly stimulated, Qin LAN and other policemen in the car can only try their best to avoid stimulating him again.


    After all, if people are in a state of stress, it is very dangerous and irrational.


    However, Chen Xin is not as excited as they think.


    Before, he did suffer a great impact and was in a state of stress, but now he is in the car, and Qin LAN has been comforting him all the time. Chen Xin has been relatively relieved.


    The reason why he didn''t let go of his gun was that he didn''t want others to touch the gun he had just upgraded.


    However, in order to avoid being worried about him all the time or being regarded as a dangerous element by the police, he still let Qin LAN close the insurance on the gun.


    Although Chen Xin has been psychologically prepared for the danger he will face and the possibility of confrontation with others since he entered the last days, it is beyond his expectation to kill people with head bashing.


    This can''t help but make Chen Xin regret that he upgraded his gun too high-end.


    Originally, I only wanted to open an automatic aiming, but it turned out to be an automatic head blow. Although it was all killing, it was obviously different.


    Chen Xin was scared, in addition to the spiritual impact of the first killing, the most important thing was that the scene of head bashing was too bloody.


    It has to be said that although the upgraded tactical eyepiece is powerful, it is a very useful tool for users.


    But when the focus and zoom function of the tactical eyepiece brings the lens close at hand, and the night vision line of sight allows him to see the whole killing process clearly, which is similar to the head bashing animation in the game, for the first time shooting and killing civilians, Chen Xin didn''t spit out. He remembered that he was wearing a protective mask, and if he vomited, he would be killed I took it with vomit on my face.


    Chen Xin as much as possible to calm his mood, let his hand is not so shaking, this will be put away the gun.


    Seeing him put the gun away, several policemen around him were obviously relieved.


    Even the police will be nervous when facing a gunman who has just shot out three heads.


    "Ah Xin, are you ok?" See Chen Xin put the gun away, Qin LAN rushed to his concern asked, very nervous Chen Xin at this time of state.


    Chen Xin nodded slightly, reached out to take off the protective mask on his face, took a deep breath, and then said to Qin LAN, "I''m a little out of breath."With that, Chen Xin didn''t wait for Qin LAN to speak, so he grabbed her arm and asked her, "ah LAN! Did I kill someone just now? I saw that I hit the three men and their heads exploded! "


    Chen Xin is not acting at this time, but he is really taking advantage of Qin Lan''s concern for him, because in the final analysis, the law of Yan state was very strict before the disaster. Ordinary people can''t even have a decent knife, let alone shoot.


    Shooting and killing, even if he was assisting Qin LAN, the policeman, should have killed three murderers, but the nature and consequences of the matter are still serious.


    "It''s all right, it''s all right! You didn''t hit the three men. I shot them. You didn''t hit the three shots. " Qin LAN is still emphasizing that she killed the three people. Looking at Chen Xin, she really dare not tell him that he killed them.


    If Chen Xin is stimulated to be good or bad, the consequences will be more serious than her lying to him that she didn''t hit.


    "But I saw the heads of the three men explode!" Chen Xin at this time in the heart of Qin LAN silently said sorry, but still can only continue to install.


    Seeing this, Qin Lan said quickly, "that''s me. I''m a sniper. Have you forgotten? It''s normal to hit three shots at such close range. It''s time for me to say sorry to ah Xin. I should have hit my chest for you to see such a scene. "

 Chapter 145

    Through the entrance of the original underground garage of the hospital, the police car entered the refuge of the first people''s Hospital in the city.


    The injured was quickly sent to treatment, while Chen Xin was sent to a ward to rest, waiting for a special psychologist to come and give him psychological counseling.


    "Ah Xin, don''t take this matter too seriously. The three people I killed were gangsters. They were robbing the injured at that time, and they were going to cut her with a fire axe. Even if you shot them, it was self-defense and courageous. What''s more, you just shot them, and I killed them." Qin LAN accompanies Chen Xin, at this time is trying to comfort his mood.


    However, at this time, Chen Xin was still in a trance, as if he had not recovered.


    "Kuang Kuang, I''m sorry. I''m a psychologist for psychological counseling. Can you excuse me for a moment, comrade policeman?" There was a knock at the door of the ward. A nice voice reminded me that the voice was very sweet, but it gave people a cold feeling.


    Qin LAN looks back. A woman doctor with glasses is standing at the door of the ward with her medical record in her arms. An ordinary white coat is worn on her, which shows a kind of fashionable temperament.


    What surprised Qin LAN in particular is that it''s such an extremely cold environment now. The female doctor is still dressed in a shirt and skirt, silk stockings and high heels, with a long hair and a hairpin on the back of her head. She doesn''t look like a doctor in a refuge at the end of the day. Instead, she looks like a special doctor who provides customized services in a private hospital before the disaster.


    Qin LAN doesn''t know why she thinks so, but somehow, Qin LAN just feels that she has an indescribable taste, and doesn''t look like a serious doctor.


    However, she soon gave up the idea, said "trouble" to the doctor, and then withdrew from the ward.


    Seeing Qin LAN leave, the woman doctor closes the door of the ward, pulls the curtain and sits in front of Chen Xin''s bed.


    He took out a pen shaped flashlight and shook it at Chen Xin twice to check his condition. The expression on the woman doctor''s face changed. She reached out and pulled out the hairpin pinned to her hair, letting her long hair fall down.


    While shaking her hair, the woman doctor put the medical record book aside and said lazily to Chen Xin, "OK, now that she has recovered, don''t pretend. Don''t you feel uncomfortable?"


    "How do you know I''m pretending?" Chen Xin saw the appearance of a female doctor, and recovered from the trance. He looked at the woman doctor who was out of the ordinary: "Dior''s red poison, is there anyone else who uses perfume in this environment?"


    This is the turn of the female doctor a little surprised, she couldn''t help picking eyebrows: "the nose is very smart, a man can smell red poison, even before the disaster is also very great."


    "It''s just that I''ve tried to do it myself before, so I''ve studied all five poisons." Chen xinlue went over the topic and looked at the doctor: "although I''m not really in a trance, I think I still need psychological counseling, so doctor, can you start?"


    Seeing this, the woman doctor shook her head, picked up the medical record book on the table again, held the hairpin in her hand and pressed it. Then she began to write on the medical record book: "I thought it would save something. Shouldn''t you men recover soon when you see a sexy woman doctor like me in the last life? You need me to give you psychological counseling, don''t you want to see more for a while? "


    "If you''ve just seen three people''s heads burst in front of you like a broken watermelon, I don''t think there are people who want to see beautiful women at this time." The woman doctor''s words were a little harsh, but Chen Xin just made an ironic remark as usual, and added: "of course, if someone uses sex to alleviate the psychological impact, when I didn''t say it."


    Hearing Chen Xin say so, the female doctor couldn''t help picking an eyebrow: "just saw three people were shot in the head, you can slow down to fight with me, it seems that your psychological quality is very good!"


    For this evaluation, Chen Xin can''t deny that: "maybe it''s the novelist''s surplus. In the past, he wrote novels to check too much information, and saw too many bloody pictures, which can be regarded as resistance. Just now, he just didn''t slow down. After all, when he saw someone''s head exploding in front of him, he still lacked the impact compared with watching videos and photos."


    The female doctor nodded her head and agreed. She continued to write the medical record with her hairpin pen and chatted with Chen Xin: "your emotional self-regulation ability is good. Now you can chat with me in such a clear and orderly way to distract your attention. Don''t think about the picture you just saw?"


    "So you''re a psychologist? Deliberately wearing such a perfume, should be deliberately create a sense of yesterday''s phantom, so that when you allow psychological counseling patients to relax, there is a kind of illusion still before the disaster? " Looking at the woman doctor, Chen Xin couldn''t help thinking that she was very interesting. On the contrary, he didn''t think about the shooting in his mind.


    At this time, the laziness on the face of the female doctor is completely disappeared, and the whole person has become a lot of serious, without the kind of sycophantic behavior that makes Qin LAN feel that she is not a serious doctor.


    "It seems that he is worthy of writing novels. I want to praise his ability of observation and analysis." The female doctor laughed and praised Chen Xin''s observation. At the same time, she finally returned the topic to Chen Xin''s current state: "after shooting, I saw someone was shot in the head. This kind of psychological stimulation really has a great impact on ordinary people. Even if the police do this, they have to carry out psychological counseling. You can adjust yourself. It''s very good to prove your psychological control It''s a good system.But I still suggest that you pay attention to rest, relax your nerves more, and don''t put too much pressure on yourself. In this end of life, everyone''s pressure is great. I have medical records of emotional collapse almost every day. You are one of the patients I''ve seen these days. It''s rare that you can adjust yourself. Don''t crush yourself. "


    As for the woman doctor''s words, Chen Xin kept them in mind, nodded to her and said, "I really broke down before, but now I''ve adjusted. But thank you for your concern, doctor. May I have your name, please


    "Since you know I spray red poison, you may as well guess my name. Red poison is a hint." The woman doctor gave a mysterious smile.


    heard the woman doctor say so, Chen Xin also can not help but start thinking and analysis, guess the name of the woman doctor and red poison perfume what is the relationship between.

 Chapter 146

    Red poison, this is a perfume from Gallo fashion brand Dior, the exact name is HYPNOTICPOISON luxehome wonderful flower, although translated literally is hypnotic poison.


    because Dior''s series of fragrances are called poison, and different kinds of perfume have different colors.


    as to what Chen Xin knew, it was because he had been asked by Mo Qingyan when he traveled to Thailand, and ran around the drugstore in Bangkok to help him buy the white money in that series of perfume, that is, white poison.


    but there were other kinds of perfume at that time, except for this white poison.


    , especially after he had been in fashion for a while, and Chen Xin had tried to make his own perfume, he was very impressed with this brand of perfume.


    However, as for the female doctor who said her name was related to red poison, Chen Xin gave up guessing after thinking about it for a while.


    It''s not that he can''t come up with the answer to the question, but that he has a simpler and more direct way to get the answer.


    "It turns out that your name is Hong Rui. Hong is really a rare surname. Let me give you a suggestion. The next time you ask someone to guess your name, remember to cover the name tag, otherwise it''s not a guessing puzzle at all. " Chen Xin took a look at the name tag on the pocket of the woman doctor''s chest, and accurately called out her name.


    Hearing that Chen Xin read out her name accurately, Hong Rui looked down at the famous brand on her chest, which made her smile: "it seems that I was negligent, but Mr. writer, your eyes are really sharp!"


    "Good at observation, accumulation of writing material, that''s all." Chen Xin didn''t continue to chat with Hong Rui. After skipping the topic, he asked her, "Dr. Hong Rui, how is my mental state?"


    "On the whole, there''s no problem, except for excessive pressure and mental tension And the more serious stress reaction, there is no other problem Red Rui turned over his hands of the medical record, read out a series of nouns, this just solemnly said Chen Xin no problem.


    However, for Hong Rui''s answer, Chen Xin also nodded his head seriously, saying that these are really no problems.


    Under the doomsday, which person''s spirit can not be tense, and can live without pressure?


    As Chen Xin had seen in the urban refuge before, even children are sensible in sharing housework for their parents. No one can live carefree in such an environment.


    A little bit of stress? This is so normal.


    As for the rest, it''s not a serious psychological problem. You can take a good rest and relax.


    After Chen Xin''s diagnosis, Hong Rui indicates that he can have a good sleep here. He turns on the stereo and plays white noise. He adjusts the light to make people feel relaxed and comfortable. At the same time, he lights a piece of incense.


    "The incense tastes a little special. Did you make it yourself, Dr. red?" The smell of incense is special, which makes Chen Xin care about it.


    "The prescription I made has the effect of calming the nerves and calming the nerves, but now it''s not easy to make it. I can''t buy many materials." Speaking of this, Hong Rui''s expression was also a little regretful: "now I can only plant some herbs in my office, which is not enough. Well, let''s not talk about that. Just close your eyes, relax and have a good rest. "


    Hearing what Hong Rui said, Chen Xin nodded and closed his eyes.


    When Chen Xin was being treated by a psychologist, the political commissar who received the news also rushed to the hospital.


    Originally, it was not necessary for the political commissar of the special police team to come forward, but Chen Xin was concerned with the installation of ground source heat pump equipment, and the people were invited by them, so the political commissar arrived at the hospital as soon as he received the news.


    After learning the story from Qin LAN, the political commissar was relieved. Although it shouldn''t be said that, killing three unimportant murderers is really not as important as Chen Xin.


    At this time, Qin LAN still insists that she killed the three people. Although Chen Xin fired, he didn''t hit the target effectively.


    The political commissar obviously accepted this saying, judging that Chen Xin just saw three murderers were shot in the head, and he fired again. Under the impact of the spirit, he thought that he was the one who killed himself.


    This kind of thing is not too difficult to deal with, as long as good psychological counseling, basically will not leave any sequelae.


    However, to be on the safe side, the political commissar said to Qin LAN: "this matter, Xiao Qin, you did not do it properly. Although the situation is urgent and you shoot, I can understand it, but it is not good for ordinary people to see this kind of scene.


    I heard that he has a good relationship with you, so you should accompany Comrade Chen more in the future, and don''t let him have any psychological burden. "


    "When I know the political commissar, I will do a good job in the follow-up work of pacifying ah Xin." Qin LAN nodded seriously, knowing that Chen Xin shot and killed the three murderers. She was more worried about Chen Xin''s psychological shadow than the political commissar.


    Just as she talked to the commissar about this, Hong Rui, who let Chen Xin sleep, came out of the ward."Dr. red, how is the patient?" The political commissar and Hong Rui are also familiar. Before the end of the day, she did a lot of psychological counseling for the special police team, so when she saw Hong Rui coming out, the political commissar immediately met her.


    "The patient''s self-regulation ability is pretty good, there is not too serious psychological shadow, just a moment by the stimulation, rest for a period of time, relax the spirit will be OK." As a professional psychologist, Hong Rui did not pull professional terms, but simply described Chen Xin''s situation.


    Hear red Rui say so, no matter be political commissar or Qin LAN feel relieved a lot, but Qin LAN is still very concerned to red Rui asked: "then how is he now?"


    "You are him..." Red Rui looked at Qin LAN, with a clear look on her face, and then replied to Qin LAN, "I''ll let him relax and have a rest. Let him sleep here tonight. If you want to accompany him, you can go in and accompany him, but try not to wake people up. There are more beds in the ward. You can rest here."


    Seeing that Hongrui said so, the political commissar also pushed the boat along with the current and said, "in this case, Xiaoqin, you can stay here and accompany Comrade Chen for the time being. You can go back when he''s OK."


    Although Qin LAN, a sniper, has been unable to carry out his task for several days because of Chen Xin, the political commissar is generous enough to let Qin LAN stay with Chen Xin for the time being.

 Chapter 147

    For Chen Xin, this may be the most comfortable sleep he has ever had in such a long time.


    The soft white noise, the warm dark light source and Hongrui''s special incense all make his nervous tension relieved.


    After relaxing, he naturally fell asleep quickly until he woke up naturally.


    Chen Xin, who opens his eyes, sees Qin LAN sleeping by the bed. He can''t help but show a surprised expression. His body moves and wakes Qin LAN.


    "Ah Xin, are you awake?" Qin LAN didn''t seem to be sleeping very much. She soon woke up and saw that Chen Xin had woken up. She quickly asked, "how do you feel? Is it better?"


    "Much better. It''s OK after a sleep. Why don''t you go to the bed next to you, Alain? How uncomfortable it is to lie down Chen Xin saw Qin Lan''s face because of a long time lying down and left the red seal, immediately some heartache.


    However, Qin LAN just laughed and comforted Chen Xin: "don''t worry about me. Anyway, I''m a special police officer. I''ve received professional training, which is nothing for me."


    With that, Qin LAN stands up and stretches. After she shows that she has no problem, she says to Chen Xin with some guilt: "I''m sorry, I let you see that scene last night. I should deal with it better and aim at the trunk."


    If Chen Xin didn''t know anything, he might have believed Qin Lan''s words, but he watched his bullet shoot from the muzzle and hit the three murderers in the head.


    But he can''t say it, because Chen Xin knows that Qin Lan''s reason for saying it is for his good to take the matter of killing someone to her.


    So Chen Xin at this time can only say to Qin LAN sorry: "I''m not good, if I can bear a little stronger."


    Speaking of this, Chen Xin also sat up from the hospital bed and asked Qin LAN, "did I shoot you any trouble? If I had known, I would not have taken out my gun! "


    Chen Xin doesn''t pretend to blame himself. He really doesn''t want to bring any inconvenience or trouble to Qin LAN.


    Qin LAN just shook her head and comforted Chen Xin: "ah Xin, if you care, you will be in chaos! Have you forgotten what''s going on now? And I''m a swat. The team has already issued documents for a long time. In case of such things, they can be shot.


    As for you have a gun, this is nothing. The commissar knows you have a gun. Besides the fact that you have a gun, what you did last night, even before, is that you really killed those three people. It''s not a crime at all


    Hearing what Qin Lan said, Chen Xin was relieved. He nodded and said nothing more.


    Seeing that Chen Xin didn''t worry about it any more, Qin Lan was relieved and asked him, "are you hungry, Xin? The food in the hospital is good. I''ll get you some breakfast. Gargle yourself and wash your face! There''s a sink over there. You can make do with it first. "


    Qin Lan said, pointing to a corner of the ward sink, at the same time from the body took out a handkerchief, handed to Chen Xin.


    After Qin LAN handed over the handkerchief, Chen Xin nodded, and Qin LAN left the ward to get food for him.


    The food of the hospital is better than that of the SWAT team. This is not to say that the treatment of the hospital is better than that of the SWAT team, but the demand of the two is different.


    What the SWAT team and the city bureau need is high calorie food that can eat and maintain consumption, while what the hospital needs is all kinds of nutritious meals that can speed up the recovery of patients, which leads to the fact that the food in the hospital is different from that in other places, or even much better.


    In a sense, hospital food is the least changed thing compared with before the disaster.


    In the canteen of the hospital, Qin LAN even got porridge and steamed bread, and even soybean milk.


    Qin LAN couldn''t help swallowing her saliva, smelling the smell of breakfast in her hands and the greedy insects in her stomach. Then she took the breakfast to the ward.


    However, when Qin LAN returns to the ward, she sees more than Chen Xin.


    Red Rui, who is in charge of treating Chen Xin, is checking Chen Xin''s condition.


    "Good morning, Dr. red!" Qin LAN and Hong Rui say hello and put down their breakfast before asking her, "how''s ah Xin? Is he all right? "


    Red Rui nodded, affirmative reply way: "the condition restores is good, has a rest to be able to go back.". After going back, take more rest and pay attention not to put too much pressure on yourself. "


    "Yes? Thank you, Dr. red Qin LAN heard red Rui said Chen Xin is OK, immediately happy to say thank you to her.


    For Qin Lan''s thanks, Hong Rui didn''t care too much. After a smile, she said to Chen Xin, "about the vanilla seeds, I''ll give you one later. If you can have more, it''s really wonderful."


    "Don''t worry, Dr. red. My greenhouse is quite big. There''s no problem growing a little vanilla." Chen Xin gave a positive reply to Hong Rui''s words.


    After Hongrui left, Qin LAN asked Chen Xin, "ah Xin, what did you just say to doctor Hong?""It''s about incense." Chen Xin didn''t hide anything from Qin LAN. He picked up breakfast and explained: "the incense used by Dr. Hong last night was made by her. I''m a little curious about her formula. I just asked about it. Red doctor said that now many herbs can''t buy materials, so they can only grow by themselves.


    I said that I could help her grow some. Anyway, my greenhouse is quite big. I can get some flowerpots to help grow some herbs. I can also make some incense later to improve the air in the shelter. If you only rely on the ventilation system, it will still taste after a long time. "


    Qin LAN heard Chen Xin say so, immediately also came to interest, very concerned said: "at that time, ah Xin, you do a good job of incense, share me! I feel like I need to smoke my room, too! "


    Chen Xin while eating has been quite a long time no steamed bread, while force nodded, agreed to Qin LAN.


    "I didn''t expect that the hospital could eat steamed bread and soybean milk. The food here is quite good!" Chen Xin eats steamed bread and gives Qin LAN soybean milk and another steamed bread. He plans to drink porridge and eat a steamed bread for breakfast.


    For this problem, Qin LAN took over Chen Xin''s steamed bread, and without affectation, while eating steamed bread and drinking soybean milk, agreed: "the materials in the hospital are directly supplied from the planting area, although the quantity is not large, but the type can still be guaranteed."


    "Then I''ll find a way to exchange seeds with them!" Chen xinruo nodded thoughtfully, obviously thinking about other people''s seeds.

 Chapter 148

    After breakfast, Chen Xin and Qin LAN, who were allowed to leave, naturally did not stay in the hospital for a long time.


    After getting the seeds from Hongrui, they left the shelter where the hospital was.


    Thanks to the fact that the tunnels between the major refuges are gradually connected, we can return to the city from the hospital instead of walking in the low temperature of minus 20 or 30 degrees above the ground. Instead, we can walk in the underground tunnels with warmer temperatures.


    And it''s just a detour to another shelter.


    With the identity of Qin Lan''s special police team, Chen Xin and Qin LAN get on a free ride and head for the refuge of the University of technology.


    "Master, what goods are you delivering?" Sitting in the car, Chen Xin felt a little dull, so he chatted with the driver.


    "Some commonly used medicines and medical consumables. Some medical supplies in the health center over there are running out. I''m going to replenish them in this car." The driver replied to Chen Xin with a smile and explained his purpose.


    Chen Xin was chatting with the driver. Seeing the smile on his face, he asked, "master, I think you are very happy! Now in this world, there are not many happy people like you


    "Hey, what''s acid! When I used to run a long distance outside, it''s not that I''ve never met a worse situation. What''s more, it''s not that life can''t go on now, it''s not that hard life has never been before, as long as you can''t die of hunger, what are you worried about? What''s more, it''s a day for you to cry and laugh. Why don''t you laugh? " The driver looked indifferent and laughed at Chen Xin again.


    Listening to the driver''s words, Chen Xin also laughed: "master, you are very open-minded!"


    "What''s open-minded or not is to be more open-minded than others. As long as life goes on, there''s nothing to be unhappy about." The smile on the driver''s face seemed to have a kind of appeal. Even Qin LAN, who had been sitting on one side and didn''t speak, couldn''t help laughing.


    Because it''s an underground tunnel, and there are no forks or curves, this car will soon arrive at the University of technology.


    After getting off at the underground parking lot of the University of technology and saying thank you to the driver, Chen Xin and Qin LAN look around and plan to take another bus to the municipal government and return to the Municipal Bureau from there.


    However, because there are not many cars from the Polytechnic University to the city government, they can only wait for a car to come out at the entrance of the underground tunnel.


    Looking at the deep underground tunnel in front of him, Chen Xin couldn''t help sighing: "our country''s infrastructure capacity is really strong, such a tunnel was dug in a few months!"


    "Is this normal operation? The tunnel is not long, and now there are plenty of manpower. It''s normal to dig and repair at the same time Qin LAN doesn''t feel much about it, but thinks Chen Xin is a little surprised: "and now there''s no such thing as defaulting on the project payment. It''s no surprise that the wages can be paid monthly or even daily. The workers point to work to eat, work harder and repair faster?"


    For this problem, Chen Xin can only pick an eyebrow and say: "I can only say that you are used to the infrastructure speed of Yanguo, but other countries are not so fast." What make complaints about


    is that Chen Xin can not help thinking of what he used to do when he was able to surf the Internet. He could often see foreigners in the outer network sigh why all the countries were quick to build up what they were doing.


    At the beginning, he could not understand why a road could be built for more than ten years in some countries. An airport was proposed to be built in 1959, and it was not officially named until 2000, and construction began in 2002.


    It wasn''t until he learned more and more that Chen Xin realized that it was not that other countries were slow, but that Yanguo was too fast.


    However, it''s meaningless to discuss this topic now, because there are two opinions about whether there is any foreign country, and who can compare the speed of infrastructure construction with Yanguo?


    Maybe Lucia still exists. Britain, Gaul and Hans, the European powers, may or may not survive. After all, their government''s ability to control the country is speechless.


    As for the Federation of the first power of the blue star, which should have survived, we can only say that heaven does not protect the Federation, and all living beings are equal under the meteorite.


    If you''re a little bit less lucky, a meteorite hits Yellowstone Park and causes Yellowstone volcano to erupt, or hits the earthquake zone or something, then you can only wish the federal people good luck.


    Thinking about these things, Chen Xin and Qin LAN finally wait for a car that just carries the shift police back to the city Bureau, and then they go back to the city Bureau smoothly.


    When returning to the Municipal Bureau, Qin Lan was told by the political commissar to accompany Chen Xin these days, so he did not go on duty, but followed him.


    Chen Xin has nothing else to do in the shelter of the Municipal Bureau. Although he has just returned from the hospital, he still cares about the installation of ground source heat pump.


    Although Chen Xin was not present, when he discussed with the engineer yesterday, Chen Xin had already had a detailed communication with the other party about the relevant technical parameters and installation problems, so even without Chen Xin, the work such as drilling and drilling was still going on smoothly.Looking at several workers drilling holes on the floor with masks, Chen Xin took the Engineer in charge of the site construction to one side and asked him loudly, "is there any problem with the installation?"


    "Not at present. Now we are drilling according to the size given by Chen Gong. Later, we will lay steel plate as the foundation. After leveling and alignment, we will put the equipment on it." The engineer explained to Chen Xin, and at the same time, he opened the drawing in his hand and explained to Chen Xin: "Chen Gong will be responsible for debugging the equipment at that time."


    "It''s my job." Chen Xin has no objection to this. Since he doesn''t need to drill holes by himself, he is also happy to stand by and watch these workers busy.


    Although Qin LAN can''t understand what these workers are doing, her task now is to accompany Chen Xin, so she doesn''t have any opinions. She just stands beside Chen Xin and accompanies him to watch the workers work.


    Soon the workers finished the drilling on the ground, and after driving in the expansion pipe, they began to install the steel plate as the anchor on the ground.


    Looking at the construction of the workers, Chen Xinxin inevitably raised an idea, that is, if he now uses the system function and spends survival to complete the installation of the six ground source heat pumps, in the eyes of these workers, what is their understanding of the installation process?


    However, this idea was dismissed by Chen Xin after a while in his mind. Although there are a lot of survival points now, and he made preparations like this at the beginning, since there are workers in the construction, it''s better for him to save a little. There''s no need to waste survival points like this.

 Chapter 149

    The installation of ground source heat pump equipment is very smooth, the workers in charge of the construction are obviously very professional, whether it is the laying of the cement base, or the leveling and alignment of the equipment, people can''t find a fault.


    This also gives Chen Xin an inexplicable sense of familiarity. From small to large, he has seen too much about these mechanical equipment and on-site construction, and has been exposed to too much.


    Whether it''s the experience of living in a chemical plant as a child, watching the construction site with his father, or his own personal experience after work, Chen Xin is very kind to the installation and debugging of this kind of equipment.


    It''s just that Chen Xin feels kind and familiar. For Qin LAN, who is on the sidelines, it''s boring.


    As a sniper, Qin LAN certainly does not lack patience, but it does not prevent her from feeling bored.


    However, since accompanying Chen Xin is a task and what she hopes to do, she can still endure the boredom in front of her, but it is inevitable that she will show some emotion.


    Chen Xin seems to be aware of Qin Lan''s emotion, so he said to her, "ah LAN, if you have something to do, go ahead. It doesn''t matter if I''m here alone."


    "Ah? No, it''s OK. I have nothing to do today. Just stay with you. " Qin LAN quickly shakes her head. Although she is a little bored and has nothing to do, she still insists on accompanying Chen Xin.


    Chen Xin is not reluctant to see this, but still said to Qin LAN: "it''s up to you, but a LAN, if you really have something to do, go ahead, don''t delay it because you accompany me."


    "Don''t worry about ah Xin. Yesterday, the political commissar said that my task in the past two days is to take good care of you." Seeing Chen Xin say so, Qin LAN couldn''t help laughing: "ah Xin, you don''t know that the political commissar and team leader of the ground source heat pump system attach great importance to it! It''s going to be the top priority in the team. I''d better stay with you. "


    This statement makes Chen Xin feel flattered, but looking at Qin Lan''s insistence, he doesn''t say anything more.


    And in his opinion, Qin LAN may be a little boring to accompany him like this, but it''s better than going out to carry out the task.


    Although it''s a bit selfish to say that, Chen Xin still hopes that people he knows will suffer less.


    The construction of the workers was very smooth. In addition, there were not many holes and footings on the ground for the six ground source heat pumps. In one morning, they basically finished the work.


    However, the last anchor used for reinforcement is fixed with cement, so it needs to be placed for a period of time after the completion of the construction, and the ground source heat pump can only be formally installed when the cement is dry.


    "What are you doing this afternoon, ah Xin?" At lunch time, Qin LAN heard Chen Xin say to wait for the cement to dry before they can continue to install ground source heat pump, naturally also asked about his arrangement in the afternoon.


    "In the afternoon, it''s mainly to drill holes in the lower layer to place the heat exchange tubes." Chen Xin answers Qin Lan''s question, seems to think that she may have any arrangements in the afternoon, so he also asks her: "a LAN, do you have anything in the afternoon?"


    For this problem, Qin LAN shook his head: "I have nothing in the afternoon, mainly worried about ah Xin you. I only experienced such a thing last night, and I have to work today. I''m afraid you can''t carry it."


    "Then you''ll worry too much. I''m just standing on the side to watch and give guidance once in a while. I won''t be tired." Qin Lan''s worry made Chen Xin laugh. At the same time, he seemed to be changing the topic and asked: "by the way, ah LAN, why did you shoot those three people so decisively last night? Generally speaking, shouldn''t we warn before shooting? "


    Hearing Chen Xin ask about last night''s incident, Qin LAN is nervous for a moment, but seeing that he asked why he shot, Qin LAN put down her heart and adjusted her mood. She replied, "I''ve already called ''don''t move'', but the three men also raised their fire axes to attack the wounded on the ground. In that case, I can only shoot."


    At this point, Qin LAN seems to be in order to strengthen Chen Xin''s impression that she killed the three people, but also deliberately apologized to him and said: "sorry, ah Xin, I shouldn''t have hit the head directly last night, if I hit the trunk, I don''t think I would have scared you."


    Chen Xin, of course, knows what''s going on. For Qin Lan''s apology, he just shakes his head indifferently: "nothing. I can''t bear it enough. But why does this happen? It''s reasonable to say that three people are not going to chop people with fire axes, right? It''s not an eschatological drama in Europe and America. In order to depict the darkness of human nature, we deliberately engage in cannibalism. "


    "Ah Xin, you think so well of things!" Qin LAN couldn''t help but smile bitterly. After denying Chen Xin''s conjecture, she replied: "people''s hearts are not so dark that cannibals come out, but some people are not so good.


    Since the disaster came, some dark minded guys thought that the time had come, and all kinds of violations of law and discipline, even vicious and brutal things had come out.


    The so-called rescue of other survivors, but in fact it''s men who kill or work as coolies, women who are forbidden to vent their desires, and those who kill for fun There are so many evils!


    The municipal government has also issued a letter for a long time. In the face of vicious incidents, it is no longer to arrest but to suppress. What''s more, the woman came out to exchange food last night. She was found by the three men and wanted to rob her things. She even wanted to kill people! "All the information Qin Lan said was obtained from the wounded after she and the police came to support Chen Xin and the wounded to the hospital last night.


    As for the three murderers who were killed, their identities were not confirmed, but their violence against the injured and their attack with fire axes were confirmed, which also confirmed the confession of the injured.


    In fact, Qin LAN has seen too many things like this. At the beginning of the disaster, she may not have shot so decisively.


    However, there have been serious injuries caused by late shooting before, and even the police have been injured. After confirming that the other party has a tendency to attack or violence, shooting directly has become a new criterion for the police.


    After Qin LAN explained to Chen Xin, he nodded his head with great understanding: "it''s really the case. It doesn''t matter that the state was strict in the past, but now in this world, who knows if the seemingly harmless people will suddenly take out a knife?"


    Chen Xin has no sympathy or regret for the three people he killed. Even if they are really three innocent people, in the case of last night, he killed them by mistake.


    Hearing what Chen Xin said, Qin LAN finally laughed: "ah Xin, it''s so nice of you to think so!"

 Chapter 150

    With professional workers and engineers, the six ground source heat pumps Chen Xin provided to the special police team were successfully installed.


    Even if we need to wait for the cement to dry completely, we don''t waste too much time. After three days, the whole set of equipment can run smoothly.


    However, the equipment is only for trial operation. Because the special police team has not yet connected the equipment with the heating equipment in the area where the special police team is located, Chen Xin just started the equipment and tested its operation.


    "There is no problem with the operation of the equipment, but whether it can run for a long time is still unknown. My suggestion is to connect the line with the hot water line in the bathroom, so that we can test whether the heating and operation are stable first. " Chen Xin proposed to the engineer beside him.


    Because the ground source heat pump equipment is not connected to the heating pipeline, the heat obtained by the ground source heat pump is stored in the energy storage tank in the form of hot water after heat exchange.


    But the capacity of the energy storage tank is limited. Under the continuous operation of six ground source heat pumps, the energy storage tank has been half full.


    Looking at the water level displayed on the energy storage tank, the engineer calculated the heating efficiency of the six ground source heat pumps, nodded his head and said, "according to the current operation data, the six ground source heat pumps can provide 2 tons of hot water in an hour, and the efficiency has been quite high!"


    Speaking of this data, engineers are obviously excited.


    Although we know that the thermal efficiency of ground source heat pump is very high, it is still very exciting to see that in half an hour, the energy storage tank that can hold 5 tons of water has been filled up by one fifth. In particular, he participated in the installation of this set of equipment.


    So looking at the equipment running so well, the engineers are also full of a sense of achievement.


    For the excitement of the engineer, Chen Xin also laughed, but he continued: "now because it''s just testing, I didn''t turn on the maximum power of the equipment. I suggest you connect the energy storage tank with the hot water pipe of the bathroom, so that you can provide hot water for the bathroom and test the stability of the maximum power long-term operation of the equipment.


    After all, this set of equipment is only made by myself. I can''t guarantee the stability of operation. It''s better to test it. "


    "It''s true that long-term smooth operation of the equipment is the key. We will transform the pipeline for testing." The engineer also agreed with Chen Xin''s words. After nodding and writing it down, he asked Chen Xin with concern: "Chen Gong, are you going back?"


    Chen Xin didn''t deny it, but nodded: "the equipment has been installed, and now it''s running smoothly, so I''ll go back tomorrow. My greenhouse is still growing vegetables. I''m a little worried that I haven''t taken care of it for a few days."


    "Oh, it''s time to go back and have a look." After listening to what Chen Xin said, the engineer also felt that he had no reason to stay.


    However, although Chen Xin felt that it was time to go back, the engineer was still worried and asked, "if there are any problems in the future operation of the equipment, will Chen Gong come back then?"


    "Please rest assured that if there is any fault in the operation of the equipment, the special police team knows where my home is, and I can come at any time." It''s about after-sales, Chen Xin is very straightforward to make a guarantee.


    After chatting with the engineer about the operation and maintenance of the equipment for a while, Chen Xin turns around and leaves, while Qin LAN is already waiting for him.


    "Ah Xin, are you going back now?" Qin LAN looks at Chen Xin beside him, can''t help but give up.


    These days, she lives with Chen Xin again. In close contact, Qin LAN feels as if she has fallen in love with him again, and she feels a little uncomfortable about Chen Xin''s departure.


    Chen Xin sees Qin Lan''s emotion, but he doesn''t want to compound with Qin LAN. At this time, he is not suitable to be too close to Qin LAN.


    Although these days he and Qin LAN have returned to the same level of intimacy as in the past, Chen Xin knows that even Qin LAN doesn''t mean to get back together, otherwise she would have spoken.


    So although Qin Lan''s mood is not right, he can only nod his head to Qin LAN and say, "well, it''s time to go back. Nobody takes care of the greenhouse these days. I don''t know how bad it is. I have to clean it up when I go back."


    Chen Xin is not so worried about whether there will be problems in the greenhouse after so many days'' absence.


    He had turned on the ground source heat pump and generator before going out, so there was no danger of power failure.


    As long as there is no power cut, the water and heating will not stop for a few days.


    However, he has to take care of all kinds of vegetables, especially the first batch of upland rice he planted should be harvested this month, and he has to go back to collect rice.


    Qin LAN naturally knows these, although a little reluctant to leave Chen Xin, but still nodded and said: "ah Xin, be careful yourself, today I will be on duty, let ah Ning send you back."


    "Xiaoding? I haven''t seen her these days. Has she come back? " Although Chen Xin was surprised that Qin LAN didn''t send her back, she also understood what she meant and didn''t say much. She was just curious why she didn''t see Ding Ning these days."Ah Ning has been on duty in other shelters these days, and he only came back on duty today." Qin LAN explains why he didn''t see Ding Ning these days. After taking Chen Xin back to his room to help him pack, he didn''t send Chen Xin away.


    Looking at Chen Xin''s back, Qin LAN doesn''t know why she feels uncomfortable. The last time this feeling appeared, it was when she broke up with Chen Xin.


    Chen Xin knows that Qin LAN is looking at him all the time, but he doesn''t look back. He just sighs and leaves the shelter in the elevator.


    Under the escort of Ding Ning and another special police member, Chen Xin returned to his home where he had been away for several days.


    The door is still covered with snow. With the help of Ding Ning and another special police member, Chen Xin was able to enter the door after shoveling away the snow.


    Ding Ning and another member of the special police force did not stay long. They just sent Chen Xin to the police station and left, while Chen Xin began to clean up his shelter.


    A few days away from home, although everywhere is still clean, the ground does not need how to sweep, but more or less fell some dust.


    As for the water circulation system, because Chen Xin is not at home these days, he doesn''t use it, but he doesn''t have to clean it up.


    The situation in the greenhouse is also good. The crops not only grow normally, but also grow better than before because Chen Xin hasn''t turned off the fill light these days.


    The only thing that bothers Chen Xin is the small shelter where he put the antenna. There is thick ice here, and even the gap between him and the outside world is completely blocked. It''s a hard work just to break the ice.

 Chapter 151

    With the hammer from the workbench, Chen Xin hammered the ice in the bunker, and couldn''t help panting.


    Leaning on his waist, Chen Xin leaned against the wall of the shelter and inhaled deeply. Although the oxygen content in the shelter was not low because of the existence of the oxygen generator and the planting greenhouse, this position was actually outside. After Chen Xin Gang had just deicing, he could not help feeling short of breath.


    He reached out and took out an oxygen bottle from his pocket, opened the protective mask on his face and took a few puffs at his nose and mouth. Chen Xin, who felt much better, put on the protective mask again and straightened up.


    "Hoo hoo, it''s going to take a long time." Chen Xin can''t help feeling that after the ice is thick, it''s not the small hammer in his hand that can knock it. If he smashes it hard, he will knock some ice debris down.


    This makes him feel a little frustrated. De icing is not an easy job. It''s not like shoveling snow. How can you clean it with a shovel.


    But the ice, especially the frozen hard ice, is very difficult to clean. In the past, if it was frozen in many places, the snow and ice would not melt until the spring.


    But now Chen Xin can''t wait until the temperature rises and the ice melts. He has to find a way to remove the ice that is at least 30 cm thick.


    To tell the truth, he had expected that there would be ice accretion, and he knew that ice accretion would be more serious in a few days, but he didn''t expect that the ice would have frozen a foot thick.


    It''s very difficult to clean such thick ice, even with professional ice pick and iron fiber, even with a sledgehammer. What''s more, there is only a small sledgehammer in the novice Chen.


    He took a hammer and hit a few more on the ice, but it seemed to have a good effect. Except for a little ice debris, there was not even a crack on the ice.


    Chen Xin can''t help but feel depressed. He laments in his heart that there is no way to solve the problem of ice accretion at one time. It would be better if he could further solve the problem of ice accretion here.


    How can it be so easy just to solve the problem? Chen Xin gave a wry smile and smashed it on the ice with a hammer.


    While smashing, Chen Xin is also thinking about how to solve the problem of ice accretion.


    The main reason for ice accretion is that the air blown out of the shelter by the vent contains water vapor, which condenses and sinks rapidly when it is cold. It has frozen into ice before it flies out, and then accumulates here.


    This can be seen from the fact that Chen Xin has been pounding ice for a long time and his protective clothing is covered with ice.


    Chen Xin sighed when he photographed the ice on the surface of the protective clothing. Although he knew the principle, it was not a matter of upgrading the ventilation system to remove the moisture from the air blown out of the vent.


    In order to remove moisture from the air, Chen Xin does know the method, that is, air drying. However, it is mainly a technology used in industrial production. It is too wasteful and expensive to use in the ventilation and exhaust of shelters.


    So in Chen Xin''s idea, it''s enough to just not freeze in the small body.


    In this case, improving the ventilation form of the exhaust outlet, or adjusting the structure of the small shelter to change the outlet to the outside can also solve the problem.


    But Chen Xin is reluctant to change the vent to the outside, because in that case, the air temperature from the vent will be significantly higher than the ambient temperature. Although it can''t be seen by the naked eye, with an infrared telescope, the vent will be as conspicuous as the searchlight in the dark.


    And although the vent is not as easy to climb in as it is in European and American movies, it will still cause a lot of problems if it is found.


    Now put it in a small bunker. Although it may be found, the danger is much less.


    So to solve the problem, it''s better to find a way to make the water vapor form ice in the small body.


    Chen Xin thought hard, suddenly a hammer hit, brain flash, finally opened the mind.


    "I''m so stupid. I''m just going to upgrade my system!" Chen Xin slaps himself on the forehead. He is annoyed that he is confused in Qin Lan''s mind these days. He doesn''t even remember that he can use the system upgrade to solve the problem.


    Chen Xin calls out the system interface and takes a look at the four digit survival on it. He has enough confidence in his heart.


    These survival points are prepared by Chen Xin to upgrade the shelter as a whole. He used to consume some points when manufacturing ground source heat pumps, but he has not been at home these days, so he has gained a lot of survival points every day. With the income of nearly 40 survival points every day, he can easily take out the survival points of upgrading the small bunkers.


    "Simple observation room"


    "upgrade scheme 1: increase the area of observation room, improve the building structure, increase the concealment and permeability, enhance the signal receiving ability of shortwave antenna, upgrade the required survival point 700"


    "upgrade scheme 2: improve the defense ability of observation room, improve the building strength, increase the heat insulation protection performance, increase the protection of observation port, upgrade the required survival point 700"


    "upgrade scheme 2: improve the defense ability of observation room, improve the building strength, increase the heat insulation protection performance, increase the protection of observation port, upgrade Cundian 1100 "


    the two upgrading schemes are not very cheap, and the emphasis is still different. However, because of the lack of building materials and the fact that the existing materials are all prepared for the overall upgrading of the refuge, Chen Xin did not upgrade in the way of both.After comparing the two schemes, he chose to spend 700 points to upgrade the first scheme, which is the option to enhance the concealment, ventilation and air permeability of the small shelter. At the same time, he can also improve the signal receiving ability of the shortwave antenna installed here.


    Although Chen Xin also wanted the second plan, the survival points should not be consumed too much. After hesitating for a moment, he gave up the upgrade option, which is obviously to evolve the small bunkers into blockhouses.


    After upgrading, the area of the small bunker has increased a little, showing a round shape as a whole, but it has not expanded too much. The observation port is still the same as before, and has not changed.


    It''s just that the original vent in the room becomes the ventilation pipe buried in the wall, which will be ventilated through the facade of the external wall of the small bunker.


    This obviously perfectly solves the problem of air vent icing in the room, and because the air vent goes from the exterior wall of the observation room, the air from the air vent will first lower the temperature in the air vent and then exhaust, which is not so obvious from the infrared perspective.


    For this point, after the upgrade, Chen Xin came out from the gate of the shelter and used the infrared visual function of the tactical eyepiece to observe the position of the observation room. He really couldn''t see the trace of the air discharged from the vent.

 Chapter 152

    Climbing up the observation room, Chen Xin wants to check the upgraded observation room.


    From the outside, the upgraded observation room is like a flat tin box embedded in the mountain. It is covered with snow. In the dark environment, it is not impressive at all.


    Just opposite the gate of the shelter is the observation port, which is still not wide enough to look out from the inside, making the whole observation room look like a machine gun bunker commonly seen in war movies. The only thing Chen Xin lacks is that he doesn''t put a heavy machine gun in it.


    After upgrading, the vent moved to the exterior wall of the "blockhouse" is a louver type design. The air discharged from the shelter will drop a lot after passing through the lower temperature pipe in the exterior wall of the observation room, and then it will be discharged from the vent on one side of the wall.


    This structural design makes the problem of icing no longer a problem for Chen Xin. There is no air with water vapor ejecting from the inside, and the observation port will no longer be sealed by the condensed ice. Chen Xin naturally avoids the heavy daily de icing work, and does not have to smash the ice with a small hammer every day.


    Chen Xin is satisfied with the upgraded observation room. However, while he is satisfied that he will not have to do the de icing work in the future, Chen Xin is really aware of his lack of physical fitness and the defects of his protective clothing.


    Although Chen Xin''s physical condition is much better than in the past few months because of doing farm work, and his physical fitness is as good as that of normal people, he is still not strong.


    So exercise, this is an option to be included in the plan.


    In the past few days at the shelter of the special police force, Chen Xin was taken to the special police force''s gym for exercise because he had nothing to do at night.


    This not only made Chen Xin''s muscles ache for a few days, but also made him realize that his refuge might also add a gym.


    After all, it can not only exercise, but also kill the free time every night, instead of playing games every night.


    It''s not that playing games is not good. It''s just that compared with playing games, exercise is more conducive to health.


    In fact, Chen Xin has a lot of spare time in the evening. After exercising for an hour, he can play games for another hour. There is no problem of choosing between them.


    It''s not complicated to add a gym, and it doesn''t have to be divided into a room. Just add some fitness equipment in the living room and exercise after dinner in the evening.


    It doesn''t even need Chen Xin to consume valuable survival, just need to get a set of fitness equipment, and even make do with it.


    When he made up his mind, Chen Xin naturally included it in his plan and recorded it in what he would do next.


    In addition, the upgrading of protective clothing is another thing Chen Xin recorded in his list of plans.


    There is no problem with the performance of the protective clothing itself, and the anti-corrosion and heat preservation effect has been very good. However, with the decrease of temperature, the protective clothing needs to deal with not the corrosive acid rain, but the severe cold caused by low temperature and strong wind, and the low oxygen environment after the oxygen content is reduced.


    Although it''s not a big problem not to adjust, Chen Xin still hopes to add an oxygen supply function to his protective clothing, so that he won''t feel difficult to breathe when he does physical work outdoors next time.


    In addition, the protective clothing itself needs to be adjusted. Although the former Long hem is good in preventing rain and keeping warm, if you wear it for physical work, you will find that the long hem is not easy to work. Relatively speaking, the short hem is more suitable.


    Therefore, the adjustment and transformation of protective clothing is naturally included in the transformation plan by Chen Xin.


    In addition to these two things, the ground source heat pump promised to Li Wensheng, Mo Qingyan and other friends will also be produced, and the dry rice that will mature this month in the greenhouse will also be harvested, as well as Li Yulong''s things


    Chen Xin finds that he has a lot to do this month.


    Fortunately, most of the things are not very urgent. After listing the things one by one and planning them, you can still handle all the things according to the planned schedule.


    The renovation of protective clothing and the gym are not urgent. If you have time, you can do it again. Instead, you promise Li Wensheng''s ground source heat pump. Chen Xin needs to do it as soon as possible, so that he can make a deal with him and get the fish and vegetable symbiosis equipment he wants.


    After all, I had made an agreement with someone before. As a result, I went to the official shelter these days. I think Li Wensheng can''t wait for these days.


    Because Qin LAN is no longer here, Chen Xin''s manufacturing of ground source heat pump is not as slow as when she was there.


    Chen Xin, who is already a skilled worker, only spent more than an hour to build a new ground source heat pump.Of course, this ground source heat pump is different from Chen Xin''s own, and there is no turbo generator added.


    The finished equipment was left on the ground beside the workbench, and Chen Xin did not immediately start making the second equipment.


    So far, in addition to the one he promised to Li Wensheng, only the equipment he promised to Mo Qingyan needs to be made. Of course, other friends also want the ground source heat pump, but Chen Xin, who has not been at home these days, has not received any new orders, so naturally he does not need to produce new equipment.


    As for the equipment to be given to Mo Qingyan, Chen Xin wanted to add steam turbine generator and fish vegetable symbiosis equipment to it. Before Li Wensheng delivered the promised fish vegetable symbiosis equipment, Chen Xin could not make it.


    So after completing the ground source heat pump for Li Wensheng, Chen Xin has no order to make.


    But it doesn''t mean that he is idle. The greenhouses that he hasn''t taken care of in a few days need to be taken care of. The dry rice that has been filled and matured also needs to be harvested. He has to be ready for harvesting.


    Although he doesn''t grow a lot of upland rice, if he cuts it by hand, Chen Xin feels that with his own efficiency, he may not be able to cut it all day, and cutting rice is a very tiring job.


    Fortunately, in exchange for a small agricultural machinery, Chen Xin can use a small harvester to harvest rice instead of cutting rice by himself.


    Of course, before the official start of harvesting, he also needs to check the small harvester that has never been used before, to understand how to use it, so as to avoid any problems caused by his improper use.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 153

    The small harvester looks like a hand-held weeder, although there is almost no difference between the two from the structure to the principle, and even a harvester can be transformed with a little modification of the hand-held weeder, but there are some differences between the two.


    Chen Xin, in particular, is a miniature combine with threshing function, which is quite different in shape.


    The principle of the two is to use the engine to drive the blade to cut the stem of the plant, but the height of the blade needs to be adjusted according to the needs of the weeder to avoid cutting the lawn too bare, while the harvester needs to increase the blade appropriately and add the guide blade to cut the stem of the crop better.


    When using, you only need to start the machine, then aim at the crops to be harvested, and then push forward at a certain uniform speed.


    This kind of small harvester has roller and crawler at the bottom. As long as you hold the handle firmly, you can harvest the crops smoothly, and there is no possibility of skew or deviation.


    Compared with manual harvesting, mechanical harvesting has considerable advantages in both efficiency and cost. After all, people are tired, but machines are not.


    Chen Xin''s one is too small, so it''s a hand-held one. Even if it''s a little bigger, there are seats on it. It''s completely comfortable to sit on.


    So when the upland rice in the field is ripe, Chen Xin has filled up the small harvester with oil and is ready to harvest after it is started.


    "Zizizi! Zizizizi With the operation of the engine, Chen Xin just needs to push the machine forward, and the sharp blade will quickly cut off the rice stalk.


    In addition, Chen Xin uses an integrated combine harvester, which directly smashes and threshes the cut rice under the action of machinery, and turns it into husked grain in a bag, leaving only the rice stalk on the ground after threshing.


    Compared with the traditional manual harvesting, which requires holding the rice straw by hand and cutting it with a sickle, this is really much simpler.


    After all, manual harvesting is connected to the stem of the rice, and it needs to thresh again. Even with the help of thresher, it is also a very heavy work.


    But with the combine, there is no such trouble, cut down the rice can be directly processed into grain with shell.


    So when a ridge of rice is cut and all the grains are in the bag next to the harvester, Chen Xin can''t help whistling happily.


    He thought that harvesting rice would be a very tiring job before he got a small agricultural machine, but he didn''t expect that it would be so easy after using the machine.


    This naturally greatly enhanced his enthusiasm, pushing the harvester to continue to harvest quickly, striving to cut all his rice fields in an hour.


    Chen Xin doesn''t have much to harvest. In a total of 200 square meters of land, there are still 50 square meters of land planted with carrots, so what he wants to harvest is just 150 square meters of rice fields.


    However, although the small harvester made the harvesting work very easy, Chen Xin still had to keep his head down, as if he were lying on the armrest of the harvester with his back bent, because the height of the hydroponic planting plate on his head was a little low, so he could not straighten up.


    Of course, it''s much easier and more comfortable than bending over to cut rice.


    So it didn''t take much time for Chen Xin to cut all the 150 square meters of upland rice.


    The cut rice is threshed by the combine and put into the bag on the machine.


    The bag was not sealed, but it was full. Chen Xin tried to reach for it, but it was so heavy that he could hardly lift it.


    One hundred and fifty square meters of upland rice are filled with three huge sacks after harvest, with an average of about 70 or 80 Jin.


    Of course, this is the grain that has not been shelled. It needs to be dried and stored for a long time.


    Although direct shelling into new rice is not impossible, but because there is still a lot of moisture, rice is likely to break.


    If this process was in the past, it would not be very troublesome. Just find a place where the ground is flat and spread out the grain to dry. As long as it is a flat cement ground, it can be used to dry the rice.


    Chen Xin had even seen farmers drying rice on the road before, so this work mainly depends on the weather, not the site.


    But now the most convenient and direct heat source, the sun, is gone, and the millet can''t be taken out to dry in the snow. The only place to dry is inside the shelter.


    However, considering the lack of space inside the shelter, Chen Xin decided to use mechanical drying to remove moisture from the grain instead of natural air drying.


    Although mechanically dried grains taste worse, it''s better than putting them in this way to cause mildew or germination.


    As for how to carry out mechanical drying, the continuous heat source of ground source heat pump is not difficult to solve.


    Whether it is to bake with a tray or to blow hot air with a blower, it is a way to remove moisture from rice.


    Chen Xin did not put the three sacks of rice into the storage room. Instead, he opened the sacks and put them in the public space.Before the dryer is made, the rice can''t be stored in the warehouse, so it''s the right way to open it first.


    As for making a dryer, Chen Xin scratched his head a little. He had never done it or seen it.


    Even the information in the computer, also did not find the relevant pictures or text description, which makes Chen Xin very worried.


    How to make this thing? Do you really want a big tray to bake?


    However, Chen Xin just gave up the idea after a while in his mind, because it''s really a bit unreliable. After all, if it''s roasted at a low temperature, it''s OK to say that it''s not dry. If the temperature is too high, it''s embarrassing to bake the rice directly.


    However, under the meditation, Chen Xin thought of the clothes dryer he used and the household dryer his mother used before.


    The principle of both is in a relatively closed space, with relatively high temperature of air to dry wet goods, remove moisture.


    Can you make something like this and use it to dehydrate the grain?


    Chen Xin thought about it and thought that this method should be feasible, but before he started, he still planned to draw a drawing to study it.


    After all, I haven''t practiced it. If I do it directly, it''s not a big deal if things break down. If I use the system to dismantle and recycle materials, but if the grain is destroyed, the loss will be at least one third of this year''s harvest.


    So for the sake of prudence, Chen Xin decided to draw the drawings of the equipment first, and then carefully study the feasibility.

 Chapter 154

    While Chen Xin was collecting his hair in order to design a drying oven for drying grains, Li Wensheng also sent two sets of fish vegetable symbiosis equipment he wanted to replace the ground source heat pump equipment Chen Xin promised him.


    Originally, Chen Xin said that he could install it at home, but Li Wensheng did not enjoy Chen Xin''s door-to-door installation service.


    When he came to find Chen Xin to pick up the goods, he met Li Yulong, who also came to find Chen Xin. After knowing this, the rich second generation used a piece of Iberian ham and a box of canned tuna to replace Chen Xin''s drilling rig and became a designated installer.


    Originally Chen Xin did not want to do so, but Li Yulong''s persuasion convinced him.


    "I think brother Chen, it''s too bold for you to do this. If someone plans to use the door-to-door installation method to cheat you out of the shelter, and then murder you or seize your shelter, what will you do?" Although Li Yulong is no less than guessing others with the greatest malice, he still thinks Chen Xin is a little too good.


    After listening to Li Yulong''s persuasion, Chen Xin agreed to Li Yulong''s request to install ground source heat pump.


    After all, Chen Xin himself to install, he does not spend survival, it is also a very troublesome thing.


    What''s more, Chen Xin also thinks that what Li Yulong said is very reasonable. Although he has a gun on his body, he is not likely to have an accident under normal circumstances. However, in case someone swindles him out of his trust and sneaks on him, it will also kill him.


    Chen Xin may have been unprepared for coming to him because he was all acquaintances. In addition, Qin LAN and Mo Qingyan are indeed trustworthy, so he subconsciously ignored this problem.


    But now that Li Yulong has put it forward, Chen Xin feels that he should still keep this matter in mind and pay more attention to personal safety.


    This is an episode, but although it is the ground source heat pump that Li Yulong helped Li Wensheng install, it still brings Chen Xin an income of 400 survival points and an increase of survival point + 4 every day.


    As for Li Yulong, he successfully cooperated with Chen Xinda.


    It has to be said that there are quite a few businessmen in the city. After Li Yulong instigated his father, in the past few days when Chen Xin stayed in the special police team, Li Yulong''s father has got through with the city government and obtained the market operation license.


    The municipal government allows Li Yulong to run the industries of market and planting farm, but correspondingly, he still needs to pay taxes as in the past, and the municipal government will send supervisors.


    But now that he has obtained the license, it is enough for Li Yulong, which means that he can carry out his own business plan.


    And Chen Xin is undoubtedly a very important part of his commercial territory. After all, both markets and farms need Chen Xin''s ground source heat pump.


    Although it is not difficult for Li Yulong to get through the relationship between the city government and get other heating equipment, as a rich second generation, he chooses the best one for everything.


    After a horizontal comparison, Li Yulong is also convinced that Chen Xin''s ground source heat pump is the most efficient heating equipment and can be self-sustaining.


    This is exactly the most important point in this era. After all, whether it is coal or fuel oil, the city needs to rely on external input and railway supply.


    If the railway breaks down and the materials cannot arrive in time, it will easily affect the market and farm operation.


    Therefore, the ground source heat pump which can be better self-sustaining has become Li Yulong''s first choice.


    Because of this, he came to Chen Xin twice in person, and brought the meat, which is very precious now, to do business with Chen Xin, in order to get the opportunity to cooperate with Chen Xin.


    After comprehensive consideration, Chen Xin did not refuse Li Yulong and agreed to take a share in ground source heat pump equipment, accounting for 20% of the shares.


    In the whole market and farm project, Li Yulong himself accounted for 50% of the shares. Chen Xin took 20% of the shares. Of the remaining 30%, 10% was paid as tax, 10% was attributed to the city government, and 10% was given to the special police force.


    Chen Xin doesn''t have any opinions on the distribution plan. It''s enough for him to take 20% of the shares. As for the separation of the municipal government and tax payment, Chen Xin has to admire Li Yulong''s ability to do business.


    And the share given to the SWAT team is also due. After all, public security and other things have to be maintained by the SWAT team.


    So after reaching the transaction intention, Chen Xin also impolitely accepted the materials sent by Li Yulong.


    Even before the disaster, Iberian ham was very rare. Chen Xin only bought a small bag of cut ham to taste it. The price of the whole ham was at least tens of thousands, which was before the disaster.


    In this last age, such a pig leg is a luxury and rare thing. It''s hard currency to exchange for anything.


    However, Chen Xin did not take this out of the idea of trading, but will be received before Jinhua Ham hanging together, intend to keep their own slowly eat.


    These two hams, if eaten carefully, will last him a year or two.


    After reaching a deal with Li Yulong, Chen Xin also gave him a list of materials he needed and explained to him that his share dividends were converted into these materials.Knowing Li Yulong''s plan, Chen Xin guessed what certificate he and the municipal government would probably offer as the general equivalent of market transaction. However, that kind of thing is far less beneficial to Chen Xin than materials. If Chen Xin wants materials, he has to replace them, so what he wants directly is materials.


    As for how to get these materials, that''s what Li Yulong needs to worry about. Chen Xin is still designing his own dryer for drying rice.


    Chen Xin considered building a layer by layer structure like the circular steamer used by his mother. After drawing the design, he gave up the idea and decided to build a large cabinet with layers of trays inside.


    Although the round is good, the structure of the split layer by layer steaming grid is more complex, and the drawer type cabinet is relatively simple.


    A large cabinet made of metal materials, which is divided into layer by layer intervals with drawer type trays, is Chen Xin''s expected dryer.


    As long as the tray is covered with rice, and then the hot air is continuously blown into the cabinet, the harvested grains can be dried to remove moisture.


    Chen Xin hesitated about the form of the tray. Although he said he wanted to make it into a drawer, it was undoubtedly a big tray. Is the bottom of the tray made of iron sheet airtight or gauze mesh breathable?


    Chen Xin looked at the design drawing he drew and fell into hesitation.

    Chen Xin still hesitated about the form of the tray. Although he said he wanted to make it drawer type, it was undoubtedly a big tray. Is the bottom of the tray made of iron sheet airtight or gauze mesh airtight?


    Chen Xin looked at the design drawing he drew and fell into hesitation.


    The whole cabinet is not difficult to design, it can be made into a four legged vertical cabinet, as for the bottom, as long as a hot air blower is placed, it is a perfect design to blow hot air upward.


    What makes Chen Xin feel embarrassed is the design of the tray used to hold rice in the cabinet. He has made a mistake in choosing the structure to use.


    In the whole cabinet, Chen Xin plans to put about 12 layers of pallets, so that he can dry more rice under the condition of ensuring ventilation. Three bags of more than 200 Jin rice can be dried in four or five times.


    But the question is whether the pallet should be made of iron sheet or gauze mesh?


    The iron tray is more load-bearing, and it can put more rice on it. However, the load-bearing performance of the yarn mesh is not very good. Obviously, it can hold less rice, and it is likely that you will have to do more work.


    Moreover, the structure of the iron sheet tray is relatively simple, and it is relatively easy to do. If you cut a piece of iron sheet and roll an edge, you will be finished.


    In the case of gauze mesh, the frame must be made first, and then the gauze mesh shall be fixed. And the fixation of gauze mesh does not mean that it is finished by nailing a few nails. Instead, it needs to press the four sides tightly with a pressing strip, so that it will not fall off.


    The key is that the yarn mesh is not durable, even if the wire mesh is often heavy, it is easy to take off the yarn.


    But if you can get the leaky mesh or screen used in the kitchen before, it''s the best. It''s hard, stronger than steel mesh, and the mesh is fine and dense, but it has enough air permeability. It''s the most suitable one to do this.


    It''s just that it''s hard to get this kind of thing now, and even if there is one, it''s not big enough. If you make that kind of fine metal mesh by yourself, even if you have system assistance, it''s a laborious job.


    After all, if there is no drawing, with the help of the power of the system, it is only to process the materials into the shape Chen Xin wants, and the assembly of parts still needs his own hands.


    So while Chen Xin was drawing designs and collecting his hair, he also asked Li Yulong to help him find a way to get a grain dryer or some metal screens.


    However, even Li Yulong, who wants to get the market, feels a bit embarrassed and says that he will try his best to find it, but there is no guarantee that he can get it.


    In this regard, Chen Xin also feels helpless. If he really can''t find a suitable screen, he can only consider overturning the vertical cabinet design and making it into a roller.


    The so-called roller is a rotatable cylinder placed horizontally. There will be baffles in it. After the grain is put in, the wall of the cylinder will be heated by electric heating and rotated at the same time. The moisture in the grain will be baked by temperature until it is dry.


    This kind of drum type and vertical cabinet type are two common types of dryer, no matter large or small models, but relatively speaking, the electric heating of drum type is undoubtedly more power consumption than that of blower.


    It is also because of energy-saving considerations, Chen Xin still wants to use the vertical dryer instead of drum type electric heating.


    Fortunately, the rice can still be stored for a few days after harvest. The dryer is not needed immediately, and it is not enough. Chen Xin can spread out the grain on the floor of the shelter and dry it naturally.


    Of course, the efficiency of natural air drying is very low, and it takes up a lot of space. The spread of more than 200 kilograms of grain is also a big pool. For Chen Xin, the only place he can think of to spread the grain is the corridor connecting the gate of the shelter and the interior.


    The tens of meters long corridor has a fully hardened cement surface, which is straight and flat. If the grain is spread out there, it can really have the effect of natural air drying.


    But in that case, it may take a week to dry the grain.


    There is also a problem to be considered here, that is, the air humidity inside the shelter is relatively high. Although the ventilation system will allow part of the water vapor to be discharged, and the water circulation system installed by Chen Xin when he first built the shelter can also recover part of the water vapor in the air, due to the existence of planting greenhouses, the air humidity is still relatively low under the effect of plant transpiration It''s higher for me.


    So this drying can make the grain dehydrate, but it can''t achieve the effect of dryer drying. There will still be some moisture in the grain, which will affect the storage.


    However, if there is no other way, we can only do so.


    However, before considering these issues, Chen Xin has a more important thing to do.


    That is cook rice!


    How can you taste the fruits of your hard work without cooking a bowl of delicious rice?


    Rice husking is not a troublesome thing. If it is dried or sun dried rice, even if it is rubbed by hand, the husk on the grain can be rubbed off, making the grain turn into brown rice.


    However, if the water removal is not enough, it can only be processed with the help of tools.


    Before the disaster, even in the countryside, few people use manual threshing. Generally, there are grain processing stations and special machines in the countryside. After the rice is poured in, white rice will come out, and the husks will be collected as chaff.Bran is a good thing. Although it''s only the husk from rice, it also contains certain nutrients. Some scholars even found that the rice bran oil contained in bran can reduce cholesterol.


    Moreover, the bran itself can be eaten. Although most of the bran is now used to raise livestock, it is not unusual for poor people to eat bran in ancient times.


    Whether it''s the idiom eat bran pharyngeal vegetables, or the northern region now has bran Wotou or bran fried noodles, this is the poor people used to eat bran in the past.


    Of course, Chen Xin doesn''t eat bran. Instead, he plans to keep it to see if he can raise some livestock himself.


    Pigs are certainly not affordable, but Chen Xin thinks he should be able to afford chickens or rabbits.


    It''s just that it''s difficult to get seedlings. Even if there are these things in the underground planting area of the municipal government, it''s difficult to get them from them.


    As for the rice after bran removal, strictly speaking, it is not the rice that people often eat before the disaster, because before the disaster, the rice that ordinary people eat is refined rice after reprocessing, and it will turn white only after the husk, that is, the cortex and germ, on the surface of the rice grain is milled.


    The rice with only husks removed should be light brown or light brown, which was popular before the disaster, or whole grain.


    Because the cortex and germ are preserved, the nutritional value is relatively higher.


    For Chen Xin, he decided to husk the rice by pounding.

 Chapter 156

    Chung rice is a very old and practical agricultural production activity, its history can even be traced back to the early history of human civilization.


    It was born in the early sprouting period of human civilization, when slash and burn farming had the earliest farming. It spread for thousands of years in Yan country, and it was not until the emergence of modern mechanical processing that it gradually replaced this ancient agricultural production activity.


    But even so, in the vast rural areas of Yan country, we can still see this ancient art.


    Chung, with the sound of Chong, means to put things in the mortar or bowl, with the pestle to smash the meaning.


    This is an ancient hieroglyph with a mortar character at the bottom and two people holding a pestle at the top in the inscriptions on bronze and Xiaozhuan, which vividly and vividly expresses the meaning of this character.


    And understand the meaning of this word, then want to restore this ancient agricultural production activities is very simple.


    Find a strong enough container, put rice in it, and then use a heavy object to pound in continuously, until all the rice husks are broken, exposing the rice grains, even if the process of pounding rice is completed.


    This container in the vast rural areas is usually made of stone mortar, more primitive and ancient is to burn a pit with stumps.


    As for the tools used for ramming, wood, stone and metal are OK, as long as they are heavy enough to pound rice husks.


    Chen Xin''s method is to use metal materials to make a big bowl and a metal rod, and then put the rice into the bowl and pound it with a metal rod.


    Because the rice was not dried, and he didn''t pound all the rice, he just processed a little to cook. It was enough to pound the rice in a big bowl.


    Put the golden rice into the bowl, pound it with a metal rod, and watch the rice husk gradually break, revealing the light brown rice grains inside. It is a very happy thing to feel the labor.


    In particular, the rice has not been dried, so it still has a faint fragrance, which makes people feel more happy and makes Chen Xin look forward to tasting the rice he planted himself.


    Because Chen Xin only pounded a bowl of rice, he didn''t spend much time pounding it.


    But at this time, the rice and bran have not been separated. Obviously, they can not be directly cooked when mixed together. We need to screen again to separate the rice and bran.


    Chen Xin knows that the most traditional method is to sieve the rice bran mixture together with a flat basket. The rice grains are heavier and fall back to the basket under the action of gravitational potential energy after sieving, while the chaff or chaff will be blown away by the wind in the process of sieving because they are lighter.


    And the dust mixed in the rice grains will fall down the gap of the flat basket, leaving only clean rice grains.


    However, at this time, there was no bamboo basket on Chen''s hands, and he could not make one himself, because the bamboo basket was made of bamboo strips. Where could he find bamboo in the end?


    If you use metal materials, it''s just a sin for yourself. How hard does it take to screen an iron flat basket?


    So at this time, we need to use a little more modern means.


    Sieve rice itself is a very classical and simple application of physics knowledge. Although the ancestors who did this may not be able to understand the physics principles contained in it, it does not prevent them from doing so.


    And know that the principle of screening rice is to use the weight difference between the grain and the husk, and use the wind to take away the chaff and chaff, then things will be easy to do.


    Chen Xin just needs to make a blower to blow the mixture of rice and bran once and blow the bran out.


    Blower is not difficult to do, especially the separation of bran and rice does not need too much wind, even the electric fan or hand blower can be competent for this work.


    With the help of the system, a hand-operated blower is made on the workbench, and a funnel is installed at the air outlet of the blower, and an opening is opened on one side of the funnel to facilitate the separation of bran, so that Chen Xin can easily get clean rice grains.


    The bran was carefully collected by him in a small bag. The light brown rice grains were put in the bowl. Chen Xin couldn''t wait to taste it.


    Clean the rice grains with water, put them into the iron pot, add proper amount of water and cook them together. The rest is just waiting for the rice to be cooked.


    While waiting for the meal to be cooked, Chen Xin went to the food storeroom to cut some Jinhua ham and Iberian ham, and took a cabbage, as well as canned pork and tuna to celebrate today''s harvest.


    Iberian ham is raw ham. The best way to eat it is to cut it and eat it raw.


    Although it can also be used to make salads, bread and fruit, or soup and other hot dishes, the former has no conditions, while the latter is too wasteful.


    So Chen Xin just cut a few pieces and planned to match them with rice.


    Jinhua ham can be used in a wide range of applications. It can be used to stir fry cabbage, stew soup, or even spread on rice and stewed together. It''s an excellent delicacy.


    So for Jinhua ham, Chen Xin cut half of his ham into thin slices and planned to put it on the rice, while the remaining half was cut into pieces and planned to fry cabbage.As for canned pork and tuna, this is just a side dish after heating.


    Humming a happy tune and cutting cabbage, Chen Xin feels that he has found the joy of cooking.


    Being able to test his cook certificate as a non professional chef is enough to prove that Chen Xin really likes cooking, but after the end of the world, he lacks food materials, which makes him unable to play his cooking skills and can only eat ready-made food, which makes him want to cook for too long.


    Now, although there are still only a few simple ingredients, we can have one or two dishes.


    Compared with the shelter food with simple seasoning, the food he was preparing was just as simple, but the taste and happiness and satisfaction he brought were totally different.


    The former is just to fill the stomach, while the latter is to really enjoy the delicious food.


    In this extremely cold and dark end, it is a very luxurious behavior to be able to enjoy the happiness brought by real food.


    But it has to be said that in many construction games, rich food can improve people''s happiness and the morale of the warriors. This is really reasonable and reasonable.


    Eating enough and eating well can really make people get a great sense of happiness and satisfaction.


    When Chen Xin added Jinhua ham to the rice and the rice gradually ripened, it gave off a strong fragrance. While swallowing, Chen Xin had the deepest experience.

 Chapter 157

    After eating the first meal after the harvest and the first formal rice when he came to the shelter, Chen Xin patted his bulging belly and felt satisfied.


    It''s been a long time since the end of the world. After all, it''s totally different between having food and being able to eat it.


    The former is half full, while the latter is full. The difference in food consumption between the two is also very large. Maybe the former is 0.8, while the latter is 1.5, and the difference is even enough for another meal.


    So Chen Xin really feels very satisfied and happy.


    After eating and drinking enough, Chen Xin didn''t turn on the game machine today. Instead, he planned to play the game with his notebook and began to ponder over the drawings of the dryer.


    If you use a notebook, you can start to work directly after playing the game. You don''t have to turn off the TV and the game console. It''s also easier.


    Just turn on the computer, but Chen Xin has opened a refuge game.


    This is a very simple pixel wind horizontal version of the game, the main plot of the game is also a family suffered a nuclear war after their own construction of an underground refuge to avoid the end.


    This game should have been played by Chen Xin a long time ago. Because the game is not big, he has always forgotten to delete it and left it on the computer desktop.


    In this game, players need to control the characters to go deep into the city to collect materials, expand their shelters, and finally collect parts to repair cars to escape from the end of waste.


    In the process of the game, the characters will encounter various crises and difficulties, some encounter enemies, some encounter excessive radiation, some get sick or hungry due to lack of water or food, and even have psychological problems due to shooting and killing


    These things need players to deal with one by one, let the shelter run, let the game characters survive, until the car is repaired to escape the end.


    But Chen Xin plays, but found a fundamental problem, let him feel particularly want to laugh.


    Because he himself is in the end of the world, because when playing this game, he has a special feeling. Chen Xin has encountered various problems in the game, some of which he did not, but the protagonist in the game has been relying on collecting food from the abandoned city to survive, which makes Chen Xin unable to accept.


    This may be the biggest gap between Eastern civilization and Western civilization. Westerners always want to plunder resources for development, while Orientals think more about farming.


    For a Yan Chinese, if he is in the last days, with the stability of the environment, he will want to plant something as long as he has the conditions, even if he just makes a flowerpot to plant a tomato or something, he will have to plant something.


    Therefore, the two modes of thinking are not the same, and the survival strategy adopted by Chen Xin is completely different from that in the game.


    Of course, maybe it''s because he has a system, plug-ins and conditions for planting. If Chen Xin, like other shelters, has no conditions for planting greenhouses, he really can''t grow them.


    However, the thinking mode of planting land is deep-rooted. As long as there are conditions, we will try our best to plant something.


    Because in the eyes of Yan people, relying on heaven, earth and parents is not as good as relying on themselves.


    If we expect to obtain materials from abandoned cities, how can we have the stability of farming our own land? You can grow your own food and exchange more with others. Isn''t that a good development model?


    And you don''t need to take the risk to collect materials from the ruins of the city. Isn''t the safety greatly improved?


    If you can farm safely, you will have food. Why risk your life to go out and fight with others just to grab a little food?


    If there are no conditions, there is no way. But if there are conditions, Chen Xin thinks that no one would like to risk his life to find food instead of farming safely.


    Maybe this is the difference between Yanguo people and people in other countries. The thinking mode of western countries towards the end of the world is similar to the wild animals in the dark forest. We all hide ourselves carefully, watch out for others, and struggle to get some food. If other people find out, it''s a fight, and the loser becomes the prey of the winner.


    But for Yan people, they are more inclined to work together to cultivate land, and then build their homes, unite and make a better life.


    It is precisely because of this deep-rooted idea, and Chen Xin himself has enough conditions to achieve all this, that he will pay special attention to his own planting greenhouse. He not only grows upland rice and vegetables to eat, but also exchanges fish and vegetable symbiosis equipment with Li Wensheng. He plans to engage in fish and vegetable symbiosis in his own planting greenhouse and raise some fish to enrich his menu.


    However, although Li Wensheng has brought the fish and vegetable symbiosis equipment, Chen Xin has not started to raise fish immediately. On the one hand, the equipment has not been installed, and Chen Xin has no place to raise fish. On the other hand, Li Wensheng has not brought live fish.


    In addition, Chen Xin has been busy collecting rice these two days, so he has left behind the installation of fish and vegetable symbiosis equipment.


    Now after collecting all the rice and eating the rice cooked by Xinmi himself, Chen Xin naturally remembers about it.As for the fish vegetable symbiosis equipment, Chen Xin''s original idea was to integrate it into the planting greenhouse, combine it with hydroponic cultivation, and grow vegetables as well as fish.


    This is not difficult to achieve. Fish and vegetable symbiosis is developed and designed for hydroponic cultivation. There will be no conflict or inappropriate place for Chen Xin to integrate fish and vegetable symbiosis equipment.


    But the fish and vegetable symbiosis equipment Li Wensheng sent is not big. According to what he said, this set of equipment is a small household equipment. The design maintenance area of one set of equipment is 30 square meters of hydroponic planting area and three cubic meters of aquaculture water.


    In terms of the consumption of a family, of course, it is enough for 3-5 people, but for Chen Xin''s greenhouse, a set of equipment can''t even cover one fifth of the area.


    Therefore, if Chen Xin wants to transform his hydroponic cultivation system into a fish vegetable symbiosis system, he can either install more sets of equipment or use these equipment as upgrading materials to upgrade the whole cultivation greenhouse again.


    However, the survival time needed to upgrade the greenhouse again is three times that before. What''s more, Chen Xin does not have enough materials. If he only provides fish and vegetable symbiosis equipment, he can only reduce the consumption of upgraded survival time by 10%.


    Fortunately, in his greenhouse, the water tanks of the hydroponic cultivation plates are separate rather than integrated, so he can first connect part of the hydroponic cultivation plates to the fish vegetable symbiosis system.


    Anyway, he only found Li Wensheng to exchange ten live fish, and for a while and a half, he could not use a large volume of aquaculture water.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 158

    With the installation function of the system, Chen Xin just moved an idea to install a set of fish vegetable symbiosis equipment originally placed in the storage room into the planting greenhouse, and connected several water tanks of hydroponic planting plates.


    The fish vegetable symbiosis system has strict requirements on the oxygen content, pH value, total nitrogen, temperature and alkalinity of the water body, so after Chen Xin installed the equipment, although he did not let the equipment run, Chen Xin still needs to use the monitoring instrument attached to the equipment to detect the water quality to ensure that it can meet the requirements.


    Fortunately, Chen Xin uses groundwater, and only adds nutrient solution to grow vegetables. There is still no problem with the water quality.


    However, due to the recent rise of groundwater temperature, the temperature of water used in the shelter is somewhat high, which is also associated with the high temperature of water in the hydroponic cultivation tray in the greenhouse.


    There''s no problem growing vegetables, but if it''s used to raise fish, unless it''s tropical fish, it will make the fish a little uncomfortable.


    So in the actual use, Chen Xin needs to consider the control of water temperature, lest the water temperature is too high, and fish farming becomes fish soup.


    This is actually very easy to control, because the groundwater used by Chen Xin is pumped up first and then stored in the water tank. When needed, it is transported from the water tank to the water pipe in the shelter.


    Therefore, as long as the groundwater with higher temperature is pumped up by the water pump, it will not be used immediately, but it will be reused after cooling for a period of time.


    As for the hot spring bath that Qin LAN wanted before, it''s easy to do. Just add a heat preservation water tank and put the hot water into the heat preservation water tank for heat preservation. It''s even simpler. You can use it as you like.


    After all, the temperature of most of the so-called hot springs is either too high or too low. There are few hot springs that are really suitable for bathing. Therefore, most of the hot springs need to be heated or cooled, and even some of them are just hot spring water transported to the pool to boil.


    With these thoughts rolling in his mind, Chen Xin had no inspiration when he looked at the drawings of the dryer on the computer. He was so upset that he didn''t bother to do it any more. So he simply turned off the computer, took a bath and went to bed.


    The efficiency of Li Yulong''s work is very high, perhaps because even in the end, there are still people under his father''s hands working for him.


    So he didn''t let Chen Xinjiu wait. After two days, he came to the door again.


    "Bruce Lee, did you get the dryer I wanted or the gauze?" Invited by Li Yulong to his luxury saloon car, sitting on the sofa, looking at Li Yulong''s happy face, Chen Xin asked curiously.


    Li Yulong didn''t sell the key, but said with a smile: "brother Chen, you are lucky. Before you told me you wanted the dryer, I went back to find the source of goods. Guess what? I found it


    "Did you really find the dryer?" When Chen Xin heard Li Yulong say this, he couldn''t help showing a happy expression and asked him, "what kind of dryer, how big is it? What''s the effect? "


    "I found it. It''s a fruit and vegetable machine used to be used in the kitchen of my father''s hotel to make dried fruits. At that time, I bought a relatively large machine, which can dry about 30 to 40 kilograms of fruits at a time. It''s also a LCD touch screen with intelligent temperature control. It''s very good." Li Yulong looks like he''s asking for credit. At the same time, he''s boasting about what he''s found.


    After listening to Li Yulong''s explanation, Chen Xin suddenly widened his eyes and said in surprise, "fruit and vegetable machine?"


    "Yes, fruit and vegetable machine! Although it was used to dry fruits, I found the manual, which said that there was no problem in drying grains. And it''s almost brand new. I bought it in the second half of last year, and I hardly used it. " Li Yulong did not expect to find such a thing.


    Chen Xin was so excited by the situation introduced by Li Yulong that he asked him, "what about the power consumption? Is it big? "


    "The power consumption is 500 watts. This thing doesn''t consume as much power as an induction cooker." Li Yulong seems to know that Chen Xin wants to ask these questions, so he takes out the prepared manual and hands it to Chen Xin: "it''s a little big, because it''s for the hotel, but it''s already towed over. It''s in my car and can be dragged in at any time for brother Chen."


    After receiving the manual from Li Yulong, Chen Xin seriously opened it and looked at it.


    This fruit and vegetable machine is really as Li Yulong said. It''s a little big, but it''s not particularly big. It''s less than one meter high. Although it weighs 40 kilograms according to the instructions, it''s not too big.


    Although you can only bake 30-40 Jin of grain at a time, some of them are very good.


    So Chen Xin nodded with satisfaction and said, "it''s really good. Now it''s hard to find such a machine. Help me get it in."


    "All right, brother Chen, you are satisfied!" Li Yulong still nodded with a smile and asked the bodyguards to help Chen Xin carry things into the shelter.


    After placing the fruit and vegetable machine in a public space and putting it against the wall, it was turned on. Seeing that it could be turned on normally, Chen Xin brought a bag of rice from the corner of the wall and was ready to try the machine.Seeing this, Li Yulong asks the bodyguard to go back to the car outside first, while he happily stays with Chen Xin and helps him put the rice into the mesh tray of the fruit and vegetable machine.


    Because it is the first time to use it, Chen Xin adjusted the temperature to a relatively low level and set it for only one hour. He planned to see the effect first.


    Seeing Chen Xin testing the machine, Li Yulong didn''t rush to go. Instead, he talked with Chen Xin about how to set up a greenhouse after he got the ground source heat pump from him.


    "Bruce Lee, if you want to build a plantation, and the ground source heat pump comes from me, then the heating problem is solved, but where are you going to set up the plantation?" Chen Xin looked at Li Yulong and asked him this crucial question.


    This is a very important problem, because in the current environment, even with the ground source heat pump provided by Chen Xin, it is still impossible to build a plantation on the surface, not only because of the bad environment on the surface, but also because the cold will affect the construction.


    In the freezing cold, how to mix cement and build bricks?


    Even if we use steel and glass to build a greenhouse, how can such a fragile structure resist the erosion of the environment?


    Compared with spending a lot of resources to build plantations on the surface, it is the most reasonable way to find a suitable underground space. Even if we use manpower to dig holes in the ground, it is better than building houses on the surface.


    So Chen Xin is very curious about where Li Yulong, who has won the support of the city government and his father, will choose the site of the plantation.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 159

    "On the issue of site selection, the municipal government has given me a choice. They have opened five small refuges that were temporarily suspended due to the problem of support for me to choose from." Li Yulong obviously considered the site selection. He explained to Chen Xin, and at the same time gave the location of five small shelters.


    Of course, there are more than five small refuges that have been closed in the urban area, but other small refuges are not among Li Yulong''s choices because of their location or other reasons.


    At present, the small shelters open to him are located around the city government, the city Bureau, the railway station and the shopping center. There are just one around the railway station and one around the shopping center. The remaining three are located around the city Bureau and the city government. One of them is even in the middle of the two big shelters.


    As for the location of these five small shelters, both Chen Xin and Li Yulong knew that this was the restriction imposed by the municipal government on Li Yulong.


    After all, although the municipal government has agreed to allow Li Yulong to engage in trading markets and plantations, it is obvious that there is still a need for supervision.


    Even if the supervisors are sent, the trading market and plantation should be located where the city government can monitor.


    This is not only convenient for supervision, but also convenient for the municipal government and Li Yulong to do business.


    "These five places..." Hearing what Li Yulong said about the location of the five sites, Chen Xin couldn''t help touching his forehead and asked him, "Bruce, how do you think about it yourself?"


    "The railway station and the shopping center, one of the two places focuses on material circulation, the other on material storage. Choosing these two places means to contact and cooperate with the railway station or the shopping center." For Chen Xin''s problem, Li Yulong did not immediately express his own ideas, but began to analyze the advantages of each site one by one.


    After listening to Li Yulong''s analysis, Chen Xin nodded and went on: "the remaining three places are all close to the municipal government or the Municipal Bureau, because you have already reached cooperation with the municipal government and the special police team. It doesn''t matter to be close to these two big refuges, so at this point, these three places have some advantages over the first two places, and there is no need to increase partners."


    Li Yulong definitely nodded and agreed with Chen Xin''s point of view: "indeed, there are enough people in the tripartite cooperation itself. Another party''s share of the cake will only let the city government and the special police team have opinions."


    "So you tend to choose from the last three addresses?" Chen Xin has understood Li Yulong''s meaning: "is it the municipal government or the Municipal Bureau?"


    "I choose the City Council." Li Yulong gave Chen Xin the expected answer.


    Chen Xin nodded and said nothing more. Instead, he asked him about the Plantation: "now that you have chosen the address, what are you going to do with that kind of plantation? Soil planting? Hydroponic farm? Or fish and vegetable symbiosis


    "I didn''t think about it in detail. My father asked a professor of agriculture in Polytechnic University to help design the plantation. When the plantation was completed, the professor and his research team would also work for me and help look after the plantation." Li Yulong himself really knows nothing about professional knowledge, but he knows how to use resources to achieve his goal.


    This answer let Chen Xin Leng for a while, but also very understanding nodded.


    "But initially, I''m going to plant some rice and vegetables, just like you, brother Yu. I''ll make sure I have something to eat first, and then I''ll consider other things. If there are conditions in the future, I''d like to plant fish and fruits, so as to enrich the variety of products." Although Li Yulong didn''t know how to farm, he knew how to grasp the market demand.


    Chen Xin nodded slightly, did not express any opinions on his plan, but after thinking about it, he asked Li Yulong, "since there are agricultural experts to plan for you, it must be possible to build a plantation, but have you considered raising poultry or livestock? I don''t know about other places, but the municipal government should have some seedlings on hand, right


    "Yes, but it didn''t come down." For this question, Li Yulong''s answer is very positive.


    "Not to talk, not to talk?" Chen Xin understood Li Yulong''s meaning, pondered for a while, and then continued: "in that case, I''ll talk about it later, but now, Bruce Lee, can you help me get a batch of seeds? The quantity is not much, but the variety should be rich. The seed package I bought before the end of the day didn''t arrive by express delivery. There are too few seeds on hand now. "


    Hearing Chen Xin''s request for seeds, Li Yulong hesitated for a moment, but he agreed soon.


    Having settled the matter, Li Yulong decided to leave when he thought it was almost done. Only before he left, he finally confirmed the supply of ground source heat pump to Chen Xin.


    For this problem, Chen Xin said that if there are materials, there will be a source of goods. He wants high-power or larger equipment. As long as he can provide the materials, he can make things.


    Li Yulong, who got the answer he wanted, left contentedly.


    Chen Xin also closed the door of the shelter again and went back to the inside of the shelter, guarding the millet he was baking.


    "young master, why do you value this man so much? It''s just ground source heat pump. The boss can''t find anyone to do it. Why do you have to cooperate with him? " On the way home, Li Yulong''s bodyguards asked him such doubts.Facing the question asked by his bodyguard, Li Yulong just looked at him and replied, "what I value is not that brother Chen can do ground source heat pump, but that he is himself."


    "Is this man so powerful? It''s rare to see you admire a man like that, young master. " Li Yulong''s bodyguard has been with Li Yulong for many years, clearly knowing how proud he is.


    As the second generation of the rich, there are few people in this city who can look up to Li Yulong, but Chen Xin is obviously more than just looking up to him.


    "When I explained to them about my market and plantation work, including my father, I thought that I wanted slavery, that I wanted people to work for free, and that I could pay at most. Only brother Chen thought that I was going to do an economic cycle. Do you think such a person is not enough to be admired?" Li Yulong looked at his bodyguard and saw that he was suddenly enlightened. Then he continued: "although little brother Chen doesn''t seem to show his talents, he can''t compare with all kinds of professionals, but he always knows the essence of things. That''s what I admire him most."


    "Listen to young master, Mr. Chen Xin is really great." The bodyguard said to Li Yulong.


    Li Yulong just laughed and told the bodyguard, "when you go back, remember to ask someone to pick out a copy of all the seeds kept at home and send it to brother Chen."

 Chapter 160

    Although Li Yulong has brought Chen Xin a fruit and vegetable dryer, it is not a large-scale dryer after all. Chen Xin still needs to slowly dry his rice plate by plate.


    Fortunately, this machine can bake 20 plates of millet at a time, with a processing capacity of 30-40 Jin at a time. A bag of millet can be dried in two times, and three bags of millet are only six times.


    From time to time, he put his hand in and turned it over. In addition to turning up the rice with water in the bottom layer, Chen Xin also felt the dryness of the rice with his hands.


    Only when it is confirmed that the rice is completely dried and there is no moisture at all, can it be bagged and stored.


    After drying more than 200 Jin of rice and pounding off the chaff, about 170 Jin of rice can be produced. If calculated by the amount of rice Chen Xin eats, he can eat for more than half a year.


    As long as he can harvest twice a year, it is enough to ensure his own ration. In the greenhouse, because he does not consider the relationship between environmental temperature and humidity changes, he can calculate according to the most suitable conditions, taking 90-110 days as a cycle, planting three seasons a year.


    In this way, Chen Xin can get more than 600 Jin or nearly 700 Jin of rice, more than 500 Jin of rice and more than 100 Jin of bran in almost a year.


    Coupled with the fact that he can harvest hundreds of Jin of vegetables every month in the greenhouse, so much food is enough to support two or three people.


    "As long as the old farmer brings the fish, he can get new seeds through Bruce Lee and Alain At last, I can eat and drink without worry. " Chen Xin calculated the output of his own greenhouse, and finally had a sense of sureness.


    There is grain in the hand, the heart is not flustered, this old saying that describes the people of Yan country no matter when it is put, it is particularly reasonable.


    Counting the resources in his hand, Chen Xin determined that he could ensure the three people''s rations. Only then did he finally put on the agenda to pick up his parents from his hometown.


    The reason why he didn''t consider taking immediate action before is that Chen Xin understands that it''s useless to bring his parents back even if he can''t guarantee enough food supply.


    Now that the food supply can be guaranteed, the prerequisite for bringing back one''s parents will be met, which can be considered formally.


    To get his parents back, Chen Xin needs to cross the 600 kilometer road of four senior officials.


    In the past, it took more than half a day to complete the whole journey by taking a high-speed, non-stop road. Now that everything is frozen and the snow on the ground is almost one meter deep, it is not easy to cross such a long road.


    So the first thing Chen Xin needs is a car that can cope with the current environment, and can run the whole journey and then run back and forth.


    This kind of vehicle, of course, is commonly known as all terrain vehicle, which can be competent for maneuvering in a variety of complex terrain and special conditions, including jungle, mountain, desert, snow, beach, swamp, water network and lake.


    Among the various all terrain vehicles, Li Yulong''s modified luxury RV is also an all terrain vehicle. However, compared with his luxury RV, Chen Xin prefers the "mang style" and "Junma" all terrain vehicles equipped by the military of Yan state.


    "Mang style" and "Junma" are articulated two compartment tracked all terrain vehicles. In addition to the cockpit, they can also drag a carriage behind.


    Among them, the mang all terrain vehicle is a heavy-duty vehicle, which can carry 30 tons at the same time with its own weight of 30 tons.


    The horse is a little smaller, with a weight of about 10 tons, a maximum speed of 60 kilometers per hour and a maximum driving distance of 500 kilometers. It can easily cross a 1.5-meter wide ditch by relying on the track, or climb a vertical obstacle of 0.6 meters and a slope of more than 30 degrees.


    Compared with Chen Xin''s own SUV, the gap between them is just like the difference between an elephant and a horse.


    With Chen Xin''s idea, getting a horse, and then transforming the rear compartment into a living cabin in the style of a RV, will be enough to meet the needs of his journey.


    Of course, it would be better to have a Mangshi. After all, Mangshi''s bigger and heavier car body also means that it can have larger cars, carry more materials and have larger living space.


    Unfortunately, before the disaster, Chen Xin didn''t think about it, otherwise Mangshi couldn''t get it, and Junma could still find a way.


    But now, he can upgrade his SUV to make an all terrain vehicle.


    And to be honest, as the snow gets deeper and deeper, Chen Xin''s SUV is becoming more and more incompetent for travel.


    Without Li Yulong''s one meter high tires, driving on this nearly meter thick snow, if you don''t pay attention, you will sink the wheels into the snow.


    So after thinking about it for a while, Chen Xin''s first thought is to change the tires of his car into tracks.


    If the speed is higher than the speed, of course, the tire wins. But if the capacity is higher than the speed, the difference between the tire and the track is as big as the difference in speed.After all, the load of the track is greater than that of the tire, which requires the engine to have a stronger output power.


    In this case, a diesel engine with high horsepower is more suitable than a gasoline engine.


    However, for the power system of this car, if it is to be reformed, Chen Xin prefers electric drive rather than fuel power.


    First of all, the electric drive is more clean and efficient, and the electric vehicle is no longer a new thing. In addition to the two problems of battery and charging, which still restrict the use of electric vehicles, this new form of vehicle has been accepted and recognized, and has become the development trend of future vehicles.


    As for Chen Xin, there is no large number of factors restricting the development of electric vehicles. Isotope thermoelectric battery as the power source and high-performance energy storage battery as the battery pack are enough to make an electric vehicle run for decades without stopping.


    For others, it''s still a remote idea in the laboratory, but for Chen Xin, it''s a matter of survival upgrade.


    And he is seriously prepared to do so. He plans to upgrade his car after completing the overall upgrade of the refuge.


    While considering the power system and driving mode, Chen Xin is also considering how to design the car''s living cabin, which is the same hatchback as mang style and Junma style? Or the one-piece car like Li Yulong''s?


    Both of them have their own advantages, but they also have their own problems. Chen Xin rubbed his lips and fell into thinking.

 Chapter 161

    "Is the air pump connected, Xiao Hai?" In the garage, Li Wensheng is checking his car, while his son Xiaohai has just put the goods into the trunk. Some worried Li Wensheng can''t help asking more.


    Xiaohai nodded: "connected, the oxygen making head is also put into the water according to your father."


    Hearing his son say so, Li Wensheng also nodded and said to him, "OK, you go back, take good care of your mother at home, and take good care of your sister. I''ll go out and deliver some goods."


    With that, Li Wensheng is about to get on the bus and get ready to drive out.


    However, Xiaohai did not obediently return to his home shelter, but said to Li Wensheng: "Dad, I want to go together!"


    "Together? No, it''s too dangerous outside! " Li Wensheng immediately frowned and refused without hesitation.


    "Dad! Let me go with you! I want to help you! " Xiaohai pleads with Li Wensheng, feeling that she has grown up and is eager to share some pressure for her father.


    But Li Wensheng refused his son''s request. He got on the car, closed the door, rolled down the window and said to his son who was still standing there: "go back, be obedient and help me take care of your mother. Taking care of your sister is the biggest help."


    With that, Li Wensheng started the car and drove it out of the garage.


    "Close the garage door and go back!" Li Wensheng poked his head out of the car window, turned around and yelled at his son, who was still standing there. Then he drove away.


    Xiaohai was disappointed to see his father driving away in the dark, and then reluctantly closed the garage door and went back to his own shelter.


    Li Wensheng drives the car carefully. He can''t see the road clearly. He relies on the buildings that are not completely buried on both sides to judge the traces of the road.


    At this time, you should be very careful when driving. A single negligence is likely to cause all kinds of accidents.


    It''s a small thing for a tire to slip or a wheel to get stuck in the snow. Li Wensheng thinks he can handle it. But if the car skids on an icy road, it''s very dangerous.


    If you hit something, it''s probably the damage of the car or even the crash.


    In today''s world, if a car breaks down, it can only be repaired by itself. It can no longer be towed to the repair shop as it used to be, and there are no replacement parts for the damaged parts.


    Li Wensheng drove to the bridge leading to the suburbs, which was the bridge Chen Xin had to pass before driving into the city.


    At this time, Li Wensheng''s psychology is full of tension, the speed has been reduced to the minimum, and he drives the car on the bridge very slowly.


    Li Wensheng was not careful. Although the bridge was built solidly, it also had a two-way six lane width, but the railings on the bridge deck were not one meter high. At this moment, the bridge deck was already covered with nearly one meter thick snow. If you drive on the snow without railings, you will rush down if you are not careful.


    Fortunately, before going out, Li Wensheng put on the anti-skid chain to the wheel, and he drove slowly enough, and finally passed the bridge without danger.


    With a long breath, Li Wensheng raised his speed a little and drove to Chen Xin''s home.


    After driving smoothly to the place, Li Wensheng took out the shortwave radio, contacted Chen Xin and told him that he had sent fish.


    In the dark snow, the vision is very poor. Even if he turns his headlight on to the high beam, it is difficult to see things 100 meters away. It is dark everywhere, just like some kind of monster, or some kind of danger lurking, which will jump out or devour him at any time.


    Although it''s hard to say, Li Wensheng is really afraid of the dark, which has something to do with his childhood experience.


    But there is no way to say this to others, because he can''t tell his wife and children that he is afraid of the dark.


    And as a man, if he doesn''t stand up at this time, can he let his wife and children go out in this situation?


    Li Wensheng thinks he can''t do such a thing.


    Fortunately, without keeping him waiting, Chen Xin quickly opened the door of the refuge, adding a ray of light to the darkness.


    "Writer, I''ve sent you the ten fish you asked for. They''re all alive. I''m afraid to die on the road. I''ve been giving oxygen and heating in the car to ensure that they don''t freeze to death." When Li Wensheng saw Chen Xin, he spoke eagerly and ostentatiously about the fish he had brought.


    It seems that he is showing some merit, but Li Wensheng himself can''t tell whether he is showing off or dispelling the fear of darkness just now in his heart by talking to Chen Xin.


    Chen Xin doesn''t seem to doubt him. He asks Li Wensheng to open the trunk and check the fish he sent. He confirms that they are all fresh. Then he nods his head and asks him to drive into the shelter.


    Let Li Wensheng drive the car into the shelter, Chen Xin just closed the door, the darkness and cold out.


    "It''s hard for you, old farmer. If it''s convenient, help me to send the fish down." Chen Xinchong and Li Wensheng politely pulled the trailer and the plastic box with water on it.


    Naturally, Li Wensheng would not refuse to help. The two men transferred the fish from Li Wensheng''s trunk to Chen Xin''s plastic box. As Li Wensheng said, the fish were still alive. One of them jumped and splashed all over their bodies.Finally, all the ten fish were transferred to the plastic box. In order to avoid water spilling everywhere, Chen Xin directly covered them.


    Li Wensheng helped Chen Xin deliver the cart and box to Chen Xin''s shelter. Although he has been to Chen Xin''s home several times, it is the first time for Li Wensheng to enter Chen Xin''s shelter.


    Looking around at Chen Xin''s refuge, Li Wensheng couldn''t help admiring: "you are still a writer. You are really good at repairing this refuge."


    Hearing this, Chen Xin picked his eyebrows and said with a smile, "we all use the same basic design. I just added a few more containers. They are all the same."


    While saying this, Chen Xin opened the door of his greenhouse and pushed the cart in.


    The fish and vegetable symbiosis equipment previously taken from Li Wensheng has already been installed in place. While opening the equipment, Chen Xin transferred the fish from the plastic box to the water tank of the hydroponic cultivation plate.


    Fortunately, the water body has been adjusted before. At the moment, there is no obstacle or maladjustment for the fish to enter the water.


    At this time, Li Wensheng curiously went into Chen Xin''s planting greenhouse. Looking at his planting greenhouse, he was filled with envy, especially the dry rice roots in Chen Xin''s field. Li Wensheng envied and said, "you are a good rice grower, writer! It looks like a good harvest

 Chapter 162

    "It''s not a good harvest. It''s enough for one person." For Li Wensheng''s admiration, Chen Xin just shook his head slightly.


    Although the yield of rice in the field is good, it is not a good harvest, especially the upland rice planted by him. Compared with rice, the yield is only 60-70% of that of rice.


    After hearing Chen Xin''s explanation, Li Wensheng nodded understandably and agreed with Chen Xin''s view, but he also put forward an idea: "writer, can you change paddy field here? If you grow rice, the yield of paddy field will be higher, right


    "Paddy field? Do you make paddy fields underground? " Chen Xin frowned, feeling that it was a bit impractical.


    However, Li Wensheng explained: "of course, it''s not good to make traditional irrigated paddy fields underground, but what if you use hydroponics? It should be possible to plant rice on a hydroponic plate and plant it on water. "


    Chen Xin was greatly inspired by Li Wensheng''s suggestion. He quickly asked, "rice itself is an aquatic crop, isn''t it planted directly in the water? How can there be water planting? "


    "Although rice is directly planted in water, there are still requirements. There should not be too much water, otherwise it will be waterlogged." Li Wensheng had been planting rice for a long time, and he knew something about it: "besides, rice only has roots and stems soaked in water. If leaves are soaked in water, they will get sick, so we can''t grow rice with too much water. As for the water planting method, it is to fix the rice on the water with the planting plate. The root system is still in the water, but the other parts are above the water


    After listening to Li Wensheng''s explanation, Chen Xin immediately understood it. He nodded and said, "I understand what you said, but this planting method is simple to say, but it should be very difficult to operate in practice?"


    "It''s not easy. I''ve seen people do it before. It''s not very easy, but it''s on the lake. It''s different if you plant greenhouses." Li Wensheng admits that it is technically difficult to grow this kind of rice, but it doesn''t mean that it can''t be done at all.


    Chen Xin nodded and said nothing more, while Li Wensheng took the opportunity to leave.


    Seeing off Li Wensheng, Chen Xin returns to the shelter, still thinking about the rice planting method mentioned by Li Wensheng.


    If rice can be grown by hydroponics, Chen Xin can certainly figure out how much the yield has been improved. This is an attractive idea.


    The normal yield per mu of upland rice is about eight or nine hundred jin in one season, but the yield of rice is much higher. Even if the super rice in Yanguo is not included, the yield per mu of ordinary rice can reach 1000 Jin to 1200 Jin, and the yield of some high-yielding varieties can even reach 1500 Jin or so.


    In addition, in most areas of Yanguo, rice can be harvested twice or three times a year. As long as the farmers are a little diligent and plant it in a scientific way, there is no problem that they can grow one or two tons of grain from the field a year.


    If we change to upland rice, even if we plant it in greenhouse like Chen Xin, we can only get more than one ton of yield by planting three seasons a year.


    Although high-yield rice relies heavily on hybrid cultivation of rice seeds and the use of fertilizer, even so, it is very attractive for Chen Xin to grow some grains.


    Maybe the next time I upgrade the greenhouse, I can modify the current planting mode?


    Chen Xin is seriously thinking about the feasibility of this idea. He has a system in hand. Even if he really changes the land in front of him into paddy field, he is not worried that his idea will not be realized.


    In addition to the ten fish Li Wensheng sent, Li Yulong soon sent the seeds he promised Chen Xin.


    Pepper, eggplant, spinach, coriander, tomato, white radish, lettuce, chrysanthemum, long beans, lentils, amaranth, cabbage


    Chen Xin counted bags of seeds sent by Li Yulong, with a happy smile on his face.


    The seed bag he bought originally contained these common crops. According to Chen Xin''s original idea, he should grow grain in half of the land, vegetables in a quarter of the land, and fruits in a quarter of the land in his greenhouse.


    In this way, even if the access to food from the outside is cut off, he can still eat and drink in the underground shelter.


    But people are not as good as God. Who can imagine that he bought the seeds, but the express didn''t deliver them to him?


    Chen Xin thought that after his doomsday, he could only eat cabbage, lettuce and carrots.


    But now Chen Xin has no such trouble. With this batch of seeds sent by Li Yulong, Chen Xin can live a life of what he wants to eat and what he wants to grow, greatly enriching his own recipes, so as not to turn his intermediate chef certificate into waste paper.


    And there is something that makes Chen Xin feel happy and excited, that is, the seeds of more than a dozen kinds of fruits.


    There are mango, watermelon, strawberry, jujube, Hami melon, kiwi, orange, litchi Although some of these varieties are not easy to grow, Chen Xin can grow them in his own greenhouse, such as strawberry, watermelon and grape.Poor God, he really hasn''t eaten fruit for nearly half a year.


    This let him get the seed already can''t help but want to plant something first, good comfort his long-awaited stomach.


    Fortunately, Chen Xin restrained this impulse.


    Now his hydroponic plate is used to grow vegetables in his greenhouse. Before this batch of vegetables are harvested, it is impossible for him to say that he has pulled up the vegetables in advance and replaced them with fruits.


    Although the fields are now empty, Chen Xin, after some consideration, decided to continue planting rice instead of taking the fields out to grow fruit.


    Of course, after the harvest of these carrots, Chen Xin still plans to reduce the area of carrots and spare a small plot to grow some strawberries or something to improve his food.


    In addition, Chen Xin must also consider what Li Yulong wants from himself for so many benefits.


    You know, Li Yulong came to Chenxin several times. Apart from the fact that the fruit and vegetable machine was not valuable, the two hams and a large number of seeds he sent were hard currency that was very popular in the last days.


    Chen Xin doesn''t feel that his relationship with Li Yulong is so good that he can give something to himself in this way without asking for anything in return. There is no good thing in this world that pays without asking for anything in return. There is no good thing before the end of the world, and even less after the end of the world.


    Chen Xin just agreed to cooperate, but the cooperation has not started yet. Li Yulong has invested so much in advance, so what he wants is more.

 Chapter 163

    Push open the heavy protective door that was originally closed, and the small shelter that was originally closed opens the door again.


    Standing at the door, Chen Xin can still see some debris scattered on the ground, which is obviously left over from the previous evacuation.


    "It looks like it needs a good cleaning." Although they haven''t entered yet, Chen Xin and Li Yulong''s first impression of this small shelter is that it''s a bit dirty.


    "After evacuating people who used to live here because of oxygen supply problems, the shelter was temporarily sealed up." The staff sent by the city government heard Chen Xin''s comments, but they didn''t feel anything wrong. They just nodded and introduced the situation here: "this refuge was originally an underground parking lot, with two floors up and down, each of 2000 square meters. Because only the second underground floor meets the civil air defense standards, only this floor has been transformed into a refuge, designed to accommodate 1000 people. "


    "A thousand? That sounds big! " Li Yulong listened to the introduction of the staff of the municipal government. As he walked in, he asked Chen Xin, "brother Chen, do you think we can use such a big place?"


    To this question, Chen Xin just shook his head and replied, "it''s not enough. Two thousand square meters is only three mu. If you are planting vegetables and fruits, it''s OK. Growing rice is not enough for the workers."


    "It''s not that expensive, is it?" Hearing Chen Xin say so, Li Yulong frowned and thought that the two thousand square meters sounds very big. He didn''t understand why Chen Xin didn''t say enough.


    "The greenhouse of my refuge is 200 square meters, and the yield per mu is 1200 Jin. If you plant rice, you can harvest 1200 Jin in three seasons a year. How much do three people eat, but not four people. Do you still think this place is big?"


    "Ah? no Two thousand square meters of land, growing food is not enough for 50 people to eat? Isn''t there super rice in our country? What''s that for? " Li Yulong seems to have been splashed with a basin of cold water, and he suddenly feels disheartened.


    However, Chen Xin said with a smile: "super rice can indeed yield 2000 Jin per mu, but it is very dependent on seeds and fertilizers. It needs to change seeds one year after planting, otherwise the degradation will be very serious. Even if you can find someone to breed for you, the operating cost will be very high, so if you build a greenhouse just to grow rice, it''s just a waste of time and energy. "


    Although Chen Xin said this with a smile, the people around him who came down with them all recognized the irony in his words.


    Because of the cooperation with the special police team, a special police team will be stationed here to maintain law and order in addition to daily patrol tasks.


    Chen Xin is selfish and persuades uncle Ding to send Qin Lan''s team. Therefore, Qin Lan also came here today with them to check the situation here and make some preparations for the future stationing of the special police force.


    When Chen Xin said that, Qin LAN frowned and asked, "but we have to plant grain! If we don''t grow food because we are short of it, won''t everyone starve to death? "


    "It''s right to say that, but Bruce Lee''s priority in planting is to obtain economic value." Facing Qin Lan''s question, Chen Xinchong continued to explain after giving her a comforting look: "of course, this is all based on the premise of planting only one kind of crop. In the current environment and existing planting conditions, the three-dimensional planting should be adopted, and the space utilization should be changed to expand the planting area as far as possible.


    In this way, the usable planting area and the variety of crops that can be planted will be greatly increased. If the fish vegetable symbiosis system is used, aquatic products can be provided, and the yield will be more guaranteed. "


    "Three dimensional planting, fish and vegetable symbiosis? How do you do this? " After hearing Chen Xin''s words, Li Yulong suddenly became excited again, as if he was not the one who had been disheartened just now.


    "It''s very simple. The ground is dug deep to make a pond for fish culture. The surface is paved with planting boards to grow rice, and then several layers of hydroponic planting layers to grow vegetables and fruits." Chen Xin simply explained a few words, looked at the empty shelter and asked Li Yulong, "Bruce, do you have a good idea of how to plan here? Two thousand square meters can''t be used for farming? "


    "It''s not impossible to use them all for farming, is it?" Li Yulong joked, but soon said, "I plan to divide two-thirds of the area for planting, and the remaining one-third of the area will be transformed into a residential area."


    "That place will be a bit crowded!" When Chen Xin heard of his arrangement, he already understood his plan. He said with a smile, but he didn''t say anything more. He just followed the staff of the city government to check the situation of the shelter.


    Although it is only a small shelter, it was built according to the standard at the beginning, and the facilities are perfect.


    Chen Xin followed the staff of the municipal government to make an inspection tour. He was very satisfied with the normal operation of the water and electricity facilities.


    After introducing the internal situation of the shelter, the staff member talked about other supporting facilities: "after the disaster, the upper floor of the shelter was transformed, but only half of it was used as a coal stack. Because the shelter is heated by boilers, which are installed on the upper floor, so the coal is also piled on the upper floor. "


    "Can the boiler be removed? We''re installing ground source heat pumps. There''s no need to keep the boilers. " When Li Yulong heard Chen Xin and the municipal government staff talking about heating equipment, he immediately didn''t want the old-fashioned coal-fired boiler.However, Chen Xin shook his head and said, "keep it. In case something happens, when the ground source heat pump fails, there is a second emergency plan. Besides, the equipment can''t run forever. It has to be shut down for maintenance. "


    "Listen to brother Chen, but half of the area upstairs is too much for stacking, isn''t it?" Li Yulong nodded to agree with Chen Xin''s opinion, but also asked his doubts: "brother Chen, do you have any plans for this?"


    Facing Li Yulong''s question, Chen Xin just patted him on the shoulder with a smile: "you have ideas. Why ask me? The boss is you. Do as you want. "


    Finish saying, Chen Xin then walked toward Qin LAN in the past, two people attitude intimate get together, seem to say what private words.


    Li Yulong watched Chen Xin and Qin LAN go to one side to talk about their business, shrugged casually, and continued with the staff of the municipal government: "in this case, the boiler will not be dismantled, can the municipal government supply coal?"


    "It''s no problem, but the city government won''t provide it for free." Although the staff of the municipal government can''t figure out who is in charge between Chen Xin and Li Yulong, they are not careless about their own work. When they heard Li Yulong talking about coal supply, they immediately talked about the price with him.

 Chapter 164

    While Li Yulong was bargaining with the staff of the municipal government, Chen Xin and Qin LAN went up to the underground floor through the original stairs of the refuge.


    "Ah Xin, will you move here later?" Qin LAN and Chen Xin come to the boiler room and look at Chen Xin checking the boiler. Qin LAN somehow asks this question.


    Chen Xin is checking the frozen boiler at this time. He suddenly hears Qin Lan''s question and looks back at her in surprise. However, he quickly replies, "no, this place will be used as a trading market and a plantation in the future. All the people who live here are workers. I will come and have a look, but I won''t move here."


    "Oh, well, I also said that if you moved here, I would live here." Qin LAN lowered her head and bit her lips. She felt that her expectation had failed.


    "If you move here, you might as well move to me. At least the conditions are much better." The meaning of Qin Lan''s words is very clear, and Chen Xin naturally responds to it.


    But Qin LAN didn''t respond to him. She just lowered her head and didn''t know what she was thinking.


    Seeing Qin Lan''s attitude, Chen Xin didn''t say anything more, just continued to check the boiler and pipes in front of him.


    This is an important part of the shelter heating system. Even if Li Yulong plans to install ground source heat pumps here, these pipes will still be used.


    However, when Chen Xin knocked on the pipes that were obviously frozen, he scratched his head to listen to the dull sound inside. It was obvious that there was still water in the pipes and they froze. It was a troublesome thing to make them run again. It needed to melt the ice in the pipes bit by bit.


    If you directly start the boiler or connect it to the ground source heat pump, because the ice in it does not melt, it is very likely that the pipe will burst under the blockage.


    However, Chen Xin is not a professional engineer, so he just checked the condition of the boiler, not along the pipeline.


    Although the boiler can still be used, it is obvious that the whole set of pipelines need to be cleaned. When the boiler was evacuated, the person in charge of the boiler must have been lazy and did not drain the water in the pipeline. Therefore, under low temperature, the pipeline must have been blocked by ice.


    "What''s good about this boiler?" Qin LAN saw that Chen Xin was still paying attention to the boiler, so she couldn''t help eating it.


    "This is the heating system of this shelter. If there''s something wrong here, it''s a big problem." Chen Xin naturally recognized Qin Lan''s taste and turned to smile at her: "there should be ice in the pipe. If you want to restore heating, you have to solve the problem of ice first. But I''m not in charge of this. Let Bruce Lee worry about it. "


    Chen Xin suddenly took off one hand''s gloves, reached out and took out a thermos box from his clothes. After opening it, he took out a sandwich made of rice and handed it to Qin LAN: "try it. This is what I made in the morning. I cooked it with my own rice and fried it with lettuce and ham. The ham is an Iberian ham from Bruce Lee, although it''s not good It''s time to eat this kind of rice cake, but now the materials are limited, so we can only eat what we have. "


    With that, Chen Xin handed the rice sandwich to Qin LAN.


    Qin LAN looked at the sandwich, some hurriedly took off the gloves and face protective mask, took a little warm rice cake sandwich and quickly bit it.


    "It''s delicious! It''s delicious Qin LAN chewed with a big mouth, smiling and delicious.


    Seeing Qin Lan''s delicious food, Chen Xin handed her the rest of the box with a smile.


    Of course, it''s not very delicious, it''s just a combination of ingredients.


    Although both of them are not particularly heavy tasting things, Chen Xin specially added lettuce to understand the greasiness, and the taste is not too bad, but there is still a long way to go between them.


    Qin Lan''s delicious food can only be attributed to the fact that she hasn''t eaten anything delicious since the end of the world. Even if it''s just a rice cake sandwich, it can make her feel delicious.


    While Qin Lan was eating a sandwich, Chen Xin suddenly asked her, "a LAN, do you know where else I can get a car in the city?"


    "Car? I''m afraid it''s very difficult. " Qin LAN has made two of three and eaten a sandwich. She swallows the food in her mouth and replies to Chen Xin: "the cars of the city government and our special police team are all the cars before the disaster, but it''s impossible to give you one.


    If you want spare parts, there is still a discussion. The three towns of Hubei Province and Jianning of Hubei Province have car parts in the materials transported by railway every week. When you pass through the city, you can get some parts. If your car breaks down, you can still get some parts for maintenance. "


    Because of fear of things cold, Qin Lan said, and picked up the second sandwich, to the mouth.


    "Is that so? That''s a bit of trouble! " Chen Xin couldn''t help frowning.


    "What''s the matter? Xin, is your car broken? If it''s going to be repaired, I can ask the repairman in the team to help you. " Qin LAN looks at Chen Xin a pair of embarrassed appearance, can''t help but concern a way.


    Chen Xin shook his head and explained to her, "my car doesn''t break down, but the problem is that ordinary SUVs can''t drive on this kind of snowy road now. I''m going to rebuild it or replace it with other vehicles that can drive in the snow.""That''s true. Not to mention the problems of oil freezing and diesel solidification, just the wheel slip is troublesome enough. Two cars in the team nearly hit each other when they went out on a mission two days ago." Qin LAN understands Chen Xin''s dilemma, but there is no good solution.


    However, although there is no way to solve Chen Xin''s problem, Qin LAN still provides him with a message: "I heard that the municipal government has also considered this problem and intends to replace the vehicles for the municipal government itself and the special police team.


    Maybe a batch of cars will come from Star City next month. At that time, ah Xin, you can ask the team leader or ask Bruce Lee to find the relationship with the city government. You must also use cars to build plantations. Maybe you can get it through Bruce Lee''s relationship? "


    "Yes? But there should be no difference between the car from Star City and the one I drive now, right? It''s nothing more than freezing protection. " Chen Xin''s mind didn''t turn around. He thought Qin Lan was talking about ordinary cars.


    However, Qin LAN laughs and returns the heat preservation box to Chen Xin after eating it. Then he explains to him, "it must be snow trucks and all terrain vehicles that pass through the snow! The city government is looking for the remote heavy industry to order tracked snow trucks and all terrain vehicles, which are much better than today''s tire cars. "

 Chapter 165

    Chen Xin doesn''t need to intervene or worry about the reconstruction of the small refuge. If he doesn''t look at the face that Li Yulong has given him so many good things, he won''t be drawn to do the scene investigation.


    As for the follow-up, it is the responsibility of Li Yulong''s professionals, and Chen Xin is not required to intervene.


    What''s more, the ground source heat pump plus fish and vegetable symbiosis system he promised to Mo Qingyan is what really needs his attention.


    After Li Wensheng delivered the fish and vegetable symbiosis system, Chen Xin had finished manufacturing the equipment, but Li Yulong''s side of the business got him in the way. For a moment, he didn''t deliver it to Mo Qingyan''s home at the first time.


    However, after dealing with Li Yulong, Chen Xin quickly informed Mo Qingyan to pick up the equipment.


    It''s not that Chen Xin doesn''t want to deliver the goods to his home. It''s that his SUV can''t drag down the whole set of equipment this time. Mo Qingyan can only drive her own pickup truck.


    "Ingredients, it''s getting harder and harder for you to leave." Welcomed by Chen Xin into his refuge, Mo Qingyan jumps out of the car and complains to Chen Xin about the difficulty of the road.


    Of course, Chen Xin also has feelings about this. Now is not before the disaster. Even if it''s freezing, rainy and snowy, there are sanitation workers and municipal departments to clean up the snow on the roads to ensure smooth traffic.


    It is very difficult to keep the roads unblocked when the snow thickness is about to exceed one meter. Especially now, the municipal government has no energy and manpower to clear the snow on the roads, and in fact, it is not necessary.


    In addition to Chen Xin and others living in the official shelters, who are still using the old roads, the city government has been gradually opening up the underground passage between the official shelters.


    When these underpasses are opened, the traffic between the official shelters can be completely turned underground, and the roads on the ground can basically be left unattended.


    But for Chen Xin, the survivors who did not join the official refuge, the difficulty of the road undoubtedly means that it is more difficult to travel and less material access.


    Mo Qingyan may be OK in the urban area. If the journey is not too far away, it''s not impossible to walk. She can make do with short driving.


    After all, she is not far from the three official shelters of the city government, the City Council and the shopping mall. Even if she wants to borrow the underground passage, it''s OK and there won''t be any trouble.


    But Chen Xin''s side is not so convenient. It''s not difficult to be far away from the urban area. The key is that to get to him, you have to pass the bridge, otherwise you need to go three times as far as possible to bypass the now dry river.


    In today''s weather, it is dangerous to cross the river and take a detour. As for whether the latter is more dangerous or the former is more difficult, it is not a matter to judge.


    "It''s getting colder and colder, and the road is getting harder and harder to walk." As for Mo Qingyan''s complaint, Chen Xin didn''t feel that it had a serious impact on him: "however, it''s self-sufficient to eat and drink, and you don''t have to worry about going out. Other people come to me for anything."


    "Yes, it''s still the food you''re comfortable with. If you have food and drink, the special police team will come to you to exchange materials and ah LAN will deliver them to your door. Don''t be too smart!" When Mo Qingyan heard Chen Xin say so, she couldn''t help showing her expression of "I''m not envious at all.".


    As for Mo Qingyan''s "not envious" appearance, Chen Xin just smiles and helps her put the ready ground source heat pump fish vegetable symbiosis equipment on her pickup truck. Then she claps her hands and says, "long Niang, now that you have this equipment, you can also be self-sufficient. You can change the seeds and fry with the old farmer, or ask a LAN if you can plant them from the municipal government District lane.


    I have calculated this system. The heat generated by the ground source heat pump and the converted electric energy are enough to support the plant growth and fish breeding of the fish vegetable symbiosis equipment, so as to ensure that there is no problem for you and Xin Xiaomei. "


    "Yes? Thank you very much Mo Qingyan heard Chen Xin say so, looking at the equipment put on her pickup, her face also showed a happy and expectant expression.


    Although she hoards a lot of materials, after more than half a year of consumption, Mo Qingyan''s total amount of materials is still decreasing.


    Although it can be maintained by the exchange of wine for goods, it is still not a long-term solution. The set of equipment provided by Chen Xin can be said to solve her urgent need.


    "You''re welcome. It''s just a set of equipment. Do you still have to say thank you to me? " For Mo Qingyan''s thanks, Chen Xin didn''t care too much: "you can go to Bruce Lee for the installation. He connected my installation of ground source heat pump. You just need to contact him."


    "OK, I see." Mo Qingyan naturally knows Li Yulong and nods to show that she has written it down.


    "Bruce Lee wants to cooperate with me to build a plantation in a small shelter sealed up by the municipal government near the Municipal Bureau. A trading market will be set up in the back. At that time, you can go there if you want to change anything." Chen Xin didn''t forget to talk to Mo Qingyan about Li Yulong''s plantation and trading market. It''s not far from Mo Qingyan''s home. It''s a very convenient trading channel for her. Moreover, Chen Xin also said, "sometimes I will go there. If you have something to ask me, you can go there. If I''m not there, you can ask Bruce Lee to help me pass on the message."Learning that there will be an additional plantation and trading market near her home makes Mo Qingyan more excited.


    For the survivors of these private shelters, the current survival of materials depends on the reserves before the disaster, as well as the exchange of each other after the disaster, or such as Chen Xin, who can be self-sustaining and self-sufficient.


    As for the city government, although it has underground planting areas and materials have been transported in by railway, these materials are basically scattered in various official shelters for the first time, and will not circulate to the market, and the city government has no intention of selling materials.


    Only some of the goods and materials circulating to the market are sold out through the people in the official shelters, and then they circulate to the black market. Moreover, these goods and materials are in short supply, and they are usually sold out as soon as they appear.


    People without access and information channels are unlikely to buy them.


    So for Chen Xin to help her build a set of self-sufficient equipment, this for Mo Qingyan, is undoubtedly a thing worthy of her good thanks.


    However, when Mo Qingyan was thinking about how to thank Chen Xin, he took out a bag and handed it to Mo Qingyan: "this is the dry rice I planted before. Recently, I have harvested it. If you want to share it, you can keep it for rice seed."


    Looking at the bag which weighs about four or five Jin handed to her hand, Mo Qingyan takes it and looks at Chen Xin. She can''t help kissing Chen Xin on the face.

 Chapter 166

    Mo Qingyan''s kiss did not bring any different changes to their relationship, because both she and he knew that it was just a kind of thanks.


    Chen Xin doesn''t take this matter to heart, and Mo Qingyan doesn''t think she will have any idea about Chen Xin. They just treat each other as brothers.


    So after Mo Qingyan kisses Chen Xin, she drags the equipment home and asks Li Yulong''s people to help install the equipment. Chen Xin is still doing her own work step by step.


    After the harvest of upland rice, he had to re fertilize the land. The herbs he promised to help Dr. Hongrui grow also needed to plan out the planting area, and the vegetables that were about to mature also needed to be harvested. It can be said that there were still a lot of things for novice Chen.


    For these things, he can only do one thing at a time. After all, there is only one person who can only do one thing at a time.


    It''s easy to say the two things of applying base fertilizer and plowing the land after the harvest of upland rice. The small agricultural machinery that Chen Xin exchanged before is not only a combine harvester, but a cultivator can combine the functions of plowing, weeding, ditching and sowing.


    All Chen Xin had to do was to get the machine ready, fertilize it and turn over the land.


    Because the soil has not hardened in winter, the soil in Chen Xin''s greenhouse is still soft. Even if he doesn''t plough, it''s not a big problem. The main reason why Chen Xin does this is to apply base fertilizer to the soil and enhance its fertility.


    After all, after a round of cultivation, the fertility in the soil has been greatly consumed. If there is no fertilization supplement, it will undoubtedly affect the growth and harvest of crops in the next season.


    The reason why high-yield seeds have such a high yield, in addition to varieties, the most important is the dependence on fertilizer.


    Chen Xin can''t stop the seed degradation and cultivate new species by himself, so what he can do is to ensure the soil fertility as much as possible, so that the crops can grow as well as he can harvest more.


    With so many things to do, Chen Xin naturally has to get up early every day, otherwise he may not have enough time.


    So after being awakened by the alarm clock, Chen Xin immediately put on his clothes, brush his teeth, wash his face and eat, and then prepared to start the day''s work.


    It has to be said that with rice, Chen Xin even had a rich breakfast.


    In the past, he could only eat shelter food or his own emergency food, but now he can cook a pot of porridge in the evening and put it there. When he gets up in the morning, white rice porridge with ham slices and two energy bars are enough to make him comfortable and full.


    After eating, Chen Xin did not immediately go to work in the greenhouse, but planned to clean up the snow outside the shelter.


    Although as he said, he can not go out for a long time, but more snow at the door will still cause some trouble to him.


    After changing into a short two-piece suit and wearing a breathing mask, Chen Xin opened the door of the shelter.


    Because Chen Xin had cleared the snow once before when Mo Qingyan came, there was no snow blocking the door and the door could not be opened.


    Chen Xin has also considered changing the door that opens outwards to open inwards, which can be quite convenient. However, after serious consideration, Chen Xin still thinks that the structural design of the door will not be changed for the time being.


    This is not because of other reasons, but because the outward opening has better protection performance than the inward opening, although it doesn''t matter whether it is used or not.


    It''s just that Chen Xin''s feeling when the gate is opened today makes him confused. The wheel used to open the gate seems to be blocked, which makes him waste some energy. He even uses a wrench to turn the wheel. There are some obstacles when he pushes the gate open. The gate is not very smooth.


    "Strange, is it freezing outside?" Chen Xin can''t help but frown, this kind of strange thing is the first time.


    After all, even when the door was almost buried by heavy snow, Chen Xin was able to open the door smoothly. This was the first time that the door was not opened smoothly.


    This made Chen Xin a little more alert. After holding the gun and flashlight in his hand, he walked out of the shelter and checked what was wrong with his door.


    However, Chen Xin was stunned when the flashlight caught the scene outside the gate.


    A man was holding a little girl in his arms. Two bodies were frozen to death on the gate. It was nothing else that hindered the wheel. It was the man''s frozen arms on the wheel.


    Because Chen Xin wanted to open the door, his frozen arm was broken at the moment.


    Looking at these two words, Chen Xin felt a pain in his heart, but he could only shake his head helplessly.


    Almost without thinking about it, he could guess what happened.


    A father, protecting his young daughter, somehow left the shelter where he lived and walked through the snow. He finally found Chen Xin''s shelter, thinking that he could be saved. But the heavy protective door not only blocked the cold, but also their cries.


    The 20 cm thick protective door is wrapped with steel plate and reinforced concrete. Even if it is hit with a big hammer, it is difficult to make any sound, let alone transmit the sound to tens of meters underground to wake Chen Xin up.Unable to open the gate of the shelter, the father and daughter could only be frozen into an ice sculpture in despair on a snowy night.


    Looking at the two corpses, Chen Xin''s heart was frozen, as if the warm breakfast had turned into ice, which made his internal organs feel frozen.


    This made him regret that he should have installed a doorbell at the door. If there was a doorbell last night and someone was outside, he would at least have a look at what happened and give the father and daughter a chance to take refuge.


    Although they won''t be allowed to enter the shelter, it''s not a problem to let them sleep in the decontamination room just across the door, so they won''t freeze to death at their own door.


    But unfortunately, people are dead. Even if Chen Xin wants to make any changes, it''s too late.


    With a sigh, instead of moving the two bodies, Chen Xin goes back to the shelter and contacts Qin LAN, telling her that there are two bodies in front of her house to deal with.


    After calling the police, Chen Xin came to the gate with a pot of hot water, melted the broken hand that had been frozen on the gate runner with hot water, and put it beside the man.


    Looking at this father who is holding his daughter in his arms until he dies and trying to cover the snow for her as much as possible, Chen Xin feels sad from the bottom of his heart.


    Life is so fragile, death is so easy, just one night of cold will let two lives leave the world, and one of them is so young, has not yet appreciated the beauty of the world.

 Chapter 167

    After receiving news from Chen Xin, Qin LAN informed the relevant departments of the matter.


    It didn''t take long for Chen Xin to wait. A car carrying people came to Chen Xin''s house.


    Qin LAN didn''t follow him. He was a special police officer who came to Chen Xin last time, and two staff members.


    Seeing the father and daughter frozen into ice sculptures in the snow, everyone could not help sighing.


    "What a pity! Why do you come outside on such a cold day?" Looking at the dead little girl, the special police who came to Chen Xin last time may be because of their youth.


    "Without professional protective equipment and enough warm clothing, people can freeze to death in a few hours in this kind of weather." Some of the staff who came to collect the corpse were not surprised, but they felt sorry for the little girl who died of freezing.


    Listening to their words, Chen Xin asked: "are there many people who freeze to death? Isn''t there an official sanctuary? "


    "Only 80% of the population is in the official shelters." With a wry smile and a sigh, the staff explained: "although the vast majority of people can enter the refuge in time before the disaster, there are still a small number of people who did not enter the refuge. They survived the first wave of the disaster by various means, but they were short of food and clothing.


    Before the weather was not so cold, they can barely survive, but the weather is getting colder and colder, and they are living more and more difficult. Although the city government has been trying to rescue, there are still many people living outside. Frozen bodies can often be found in the urban area, and they don''t even know when they died. "


    While saying this, the two staff members are trying to separate the father''s and daughter''s corpses so that they can be put into the body bag, but the frozen corpses are not so easy to separate, especially when the father holds his daughter firmly in his arms. If they want to separate, they can only break the father''s arm.


    Seeing this situation, the expressions on the faces of the two staff members were more complicated. When the attempt failed, they sighed and could only put the father and daughter into a body collecting bag.


    Looking at the corpse in the bag, both Chen Xin and the young special police officers looked very uncomfortable.


    "Brother Chen, if it''s OK, I''ll go first." Seeing that the body had been restrained, the young special police officer said goodbye to Chen Xin and was ready to leave.


    See young special police to go, Chen Xin did not stay, just asked him: "a LAN today is a mission?"


    "Well, sister LAN, their team went to the shelter in the county. It was said that there was trouble there." The young special police officer nods and tells Chen Xin where Qin LAN is going. Then he turns around and drives away with two staff members.


    Watching them leave, Chen Xin looks back at the blood left behind when he broke his hand because it was thawed on the runner at the door before he left the shelter. He can''t help sighing again.


    But the deceased is gone, and Chen Xin does not continue to be sentimental. He goes back to the shelter and closes the door. Today, he has already delayed a lot of time and has a lot to do.


    On the other side, Qin LAN and his teammates are sorting out their equipment and preparing for the mission.


    "Last night, baling county government received a call for help from No.2 shelter in Baling county. A group of gangsters intended to control the whole shelter and achieve their criminal purpose." It was still Li Tou who led the team. He was making a task report very seriously: "after receiving the call for help, the county government of Baling County attached great importance to this matter, and immediately contacted the county special police team and the armed police. They rushed to the scene for disposal at the first time.


    However, the criminals occupied the shelter and blocked the gate. The county special police team and the armed police lacked heavy weapons and could not forcibly enter the shelter, so they asked the city government for help.


    The leaders of the Municipal Bureau also told us to attach importance to this matter. In addition to us and Lao Zhang, the municipal Armed Police Corps sent an armored car and a squadron of soldiers as support.


    After arriving at the scene, the negotiation experts will negotiate first. If the criminals can be persuaded to give up resistance through negotiation, it is naturally the best solution. However, if the criminals resist stubbornly, the armed police force will use armored vehicles to forcibly break through the gate of the refuge, and we will attack it together with the armed police force.


    At that time, the armed police force will be responsible for killing the rebellious criminals as much as possible, while we will be responsible for rescuing the hostages that may exist. In addition, if the criminals agree to negotiate, we will be responsible for protecting the negotiators. "


    After introducing the task, Li Tou looked at his team members sitting in the armored car and asked them seriously, "do you understand?"


    "I understand!" All the people roared, then they were silent and did not speak any more. They just adjusted their state seriously and grasped the weapons in their hands.


    As a sniper, Qin LAN took the bullets of his beloved sniper gun out of the magazine one by one, and then pressed them one by one, so repeatedly.


    This is what she does every time she performs a major task, just to make her inner mind calm and focused, so that she can perform the task in the most calm and focused state.


    The sniper doesn''t have a second shot. This is what Qin Lan''s instructor told her when she first received sniper training.The instructor told her that in the battlefield, the sniper must be absolutely calm, and every shot must have absolute confidence to hit, because there will not be a second chance to fire, the sniper must hit with one shot.


    So before you shoot, you have to calm down and focus all your attention.


    Qin Lan''s action of disassembling and assembling bullets is exactly the small action that she uses to make her focus.


    Qin Lan''s teammates have been familiar with Qin Lan''s habits for a long time, and did not disturb her. When the vehicle arrived at the mission site, others got off the vehicle and began to prepare for the battle, Qin LAN finally pressed the last bullet into the magazine, loaded the magazine into the gun body, stood up and entered the shooting position on the roof, and set up the gun.


    Because it''s a heavy attack mission, although it needs sniper cover, it doesn''t need to find additional shooting positions. The shooting opening on the roof is the most suitable position.


    Qin LAN doesn''t like lying position shooting. On the one hand, lying on her stomach always makes her feel oppressed and uncomfortable. On the other hand, if she lies on the roof of the car in this weather, she will soon be frozen with a gun.


    Relatively speaking, standing in the car body, just the gun and upper body out, can let her keep the best shooting state.


    Outside, the special police and the armed police have been in place. The lights of several police vehicles are facing the gate of No. 2 shelter in Baling county. On the armored police vehicle coming from the armed police, a 12.7mm revolver machine gun has been aimed at the gate of the shelter. With its terrorist shooting speed of 2000 bullets per minute and the armor piercing ability of large caliber bullets, it is enough to tear open the gate of the shelter.

 Chapter 168

    Five armored vehicles of the special police and the armed police stopped at the gate of No. 2 shelter in Baling County, putting on a siege.


    Although only one of the five armored vehicles is equipped with heavy weapons on the roof, and the other four are only light personnel carriers, it only needs this heavy machine gun to break through the gate of the refuge.


    The machine gun didn''t ring, although the shooter had put his finger on the trigger, and the aiming center of the machine gun in the field of vision had aimed at the gate of the refuge in front of him.


    "Still no response?" Li Tou looked at the snow-white shelter gate illuminated by the lights of five armored vehicles, and asked another special police officer who led the team.


    He, the special policeman, the officer in charge of the armed police force, and the commander of the special police force and the armed police force of Baling county together constitute the temporary command of the scene. All decisions will be made by the temporary command group composed of five of them.


    "The phone got through, and the station called, but no one answered." The other special police officer in charge of the team, whose surname is Zhang, is also called Lao Zhang. However, his temper is a little impatient: "if I say it''s better to attack by force, I don''t need to use a heavy machine gun to load explosives on the four rotating shafts of the gate to unload this kind of protective door."


    The gate of No.2 refuge in Baling county only uses ordinary civil air defense door. According to Lao Zhang, a blasting expert, there are many ways to open the door.


    In fact, Li Tou supports Lao Zhang''s idea that he wants to attack. It''s not a good thing for everyone to wait in preparation on such a cold day. In case his brother freezes up and something goes wrong, Li Tou thinks it''s not worthwhile for them to pick their skin and cramp.


    Now it''s not like before. The confrontation for a few hours is nothing more than patience. Now it''s more about whether the team members can bear the severe cold of dozens of degrees below zero.


    There is no reason to say that criminals spend time with the police in the shelter, while the police can only be exposed to the cold in the ice and snow.


    In fact, the armed police officers in charge of commanding also tend to attack directly. Although the soldiers can persist, it is difficult to make a breakthrough in this confrontation in a short period of time, and he does not want to let the soldiers under him suffer cold.


    "Give an ultimatum, wait another ten minutes, we''ll go in if they don''t open the door!" In the end, the officer made a decision.


    After receiving the order, someone immediately followed the instructions, and Li Tou, Lao Zhang and the other two commanders also ordered their soldiers to prepare for the attack.


    Ten minutes went by in a flash. Seeing that the gate was still closed and there was no sign of opening it, the armed police officer in charge of the command gave the order of a strong attack.


    However, just as they were about to demolish the gate of No. 2 shelter in Baling County by blasting, the wheel on the gate moved.


    The gate of No. 2 shelter in Baling County, which was closed, was finally opened.


    pushing the small cultivator, Chen Xin hummed happily as the blades on the machine smashed the soil and the remaining rice roots together.


    After harvesting this month''s vegetables, he also began to plow the land to plant the second crop of rice this year.


    Although it is intended to change upland rice into rice, because the current conditions are not available, the second crop of rice is still upland rice.


    At present, the rice seed has begun to raise seedlings. He needs to turn out the ground before the seedlings grow.


    Chen Xin''s face is wearing a protective mask, because the greenhouse that has just been fertilized has a strong smell. Without the protective mask, the taste is too strong.


    The fertilizer is still from his water treatment reactor, which is the product of fermentation from toilet wastewater treatment. It is traditional organic fertilizer.


    In the past, these fertilizers may not be enough, but with the harvesting of the first crop of rice and the biomass produced in the oxygen generator, the raw materials for composting are temporarily enough.


    Chen Xin smashed these rice stalks and put them into the upgraded reactor. Of course, it is impossible to turn these rice stalks into fertilizer after a few days of fermentation. However, the remaining parts and the improvement of fermentation efficiency after the system upgrade still make Chen Xin get enough fertilizer.


    These fertilizers are sprinkled in the field and then turned into the soil with the ploughing. This method is called base fertilizer, which can affect the growth of crops in the whole season.


    Before there was no chemical fertilizer, applying base fertilizer and ploughing were very important parts of traditional agricultural production activities. Even with modern agricultural production activities of machinery and chemical fertilizer, it was still an indispensable agricultural production activity.


    Pushing the tiller, the small fields were soon turned over.


    Looking at the field, Chen Xin''s face is smiling. At the same time, he is looking forward to a good harvest this season.


    "Grow up quickly!" After cleaning up the used cultivator, Chen Xin looks at the seedlings on one side and sincerely hopes that they can grow up faster.


    However, no matter how urgent Chen Xin''s desire for seedlings to grow up is, the growth of plants should follow the objective laws of nature, and it is impossible to grow up in an instant.So even though Chen Xin''s eyes were eagerly staring at these seedlings and sincerely looking forward to their rapid growth, these seedlings still looked like new shoots breaking the ground, and had no change.


    But even so, Chen Xin is still very happy to stare at these seedlings, as if they have become a heavy harvest.


    Although he had high expectations for the seedlings, Chen Xin turned around to do other things after seeing them for a while. After all, in addition to these seedlings, there are other important things for him to pay attention to.


    The herbs promised to Dr. Hongrui have been sown, because they have not been planted, and Chen Xin has no foundation. He just planted one third of the seeds first, and planted them on a specially reserved planting board according to the planting method explained by Dr. Hongrui.


    At present, the situation is still good, the seeds are basically germinated, but whether they can grow and eventually bring harvest, Chen Xin is not sure.


    After all, in the process of plant growth, problems can''t be more normal. Although his greenhouse seems to be due to the upgrading of the system, there hasn''t been any crop disease for more than half a year, Chen Xin still feels that he can''t be careless.


    After checking all the crops carefully and making sure there was no problem, he left the greenhouse.


    According to the Convention, Qin LAN will send this month''s supplies today, and Chen Xin also needs to sort out the harvested vegetables and prepare for the exchange.

 Chapter 169

    As usual, the car of the special police team arrived at the gate of Chen Xin''s shelter on time, bringing materials for exchange, and preparing to transport the vegetables Chen Xin produced this month.


    It''s just that Chen Xin feels very strange that it''s not Qin LAN who follows the car today, but the young special police officer who came here before and another special police officer he doesn''t know.


    "Why are you here today? Didn''t Alan come?" Chen Xin looked at the two special police officers who came to pick up the goods and couldn''t help frowning.


    Qin LAN has made an appointment with him to come to pick up the goods every month and stay for two days. She is not a person who will break her promise. If there is no delay, Qin LAN will never break her appointment.


    Sure enough, Chen Xin asked why Qin LAN didn''t come. The two special police officers looked at each other, with hesitation and uneasiness on their faces.


    This made Chen Xinyue worried and asked them nervously: "what''s wrong with Alain? Is there something wrong? "


    "This Brother Chen, don''t be nervous. Sister LAN didn''t come because she was injured. Now she is in hospital! " The young special police officer who had been here before quickly calmed Chen Xin''s mood. He knew that the relationship between Chen Xin and Qin Lan was unusual, and he quickly explained the cause of the matter: "yesterday, sister LAN went to perform the task, but as a result, there was an accident. Sister LAN was injured in the shoulder by a stray bullet, and now she is in the hospital for treatment."


    It seems that she is afraid of Chen Xin. The young special police officer also added a consolation to Chen Xin: "brother Chen, don''t worry too much. Sister LAN is only bruised by stray bullets, and the situation is not serious. The doctor is afraid of her wound infection, so she is sent to hospital for treatment. She really doesn''t matter!"


    Listening to the explanation of the young special police, Chen Xin''s face is completely dark. He didn''t expect that Qin LAN would have such a thing.


    Although it seems that the situation in the mouth of young special police officers is not serious, they are only bruised by stray bullets, but if you think about it with your head, you know that there will be such a thing as being bruised by stray bullets. It is obvious that there has been a gunfight, otherwise, where are the stray bullets coming from?


    Although Qin LAN is a sniper, the sniper should be the most hidden combat unit on the battlefield. Now the snipers are injured, how fierce should the battle be?


    Chen Xin can''t restrain his worry at the moment. He wants to go to the hospital to see Qin LAN immediately.


    But he has to solve the problem before he can go to the hospital.


    So Chen Xin can only restrain his nervousness and worry, helping the two special police officers count the vegetables they used to trade this month, but he didn''t see the supplies they sent. He let them pile up in the preparation room at the gate, so he was ready to drive out to visit Qin LAN in the city.


    Seeing Chen Xin so excited, two special police officers quickly stopped him.


    "Brother Chen, calm down first. You can drive to the hospital like this. It''s easy to have an accident on the way. You''d better take our car!" The young special police didn''t stop Chen Xin from going to the hospital, just didn''t let him drive: "now the road condition is so bad, sister LAN is OK, don''t brother Chen, you have an accident first!"


    Chen Xin listened to the young special police officer''s words, hesitated for a while, then immediately gave up the idea of driving to the city, nodded, closed the door of his refuge, and went to the city by car with them.


    In the hospital in the city, Qin LAN is leaning on the bed with her arms suspended. Her face is a bit remorseful and scared.


    Her coat and clothes were untied, revealing her left arm and shoulder, which was now wrapped in a thick bandage and hung around her neck.


    Qin LAN never thought that she would be hit by stray bullets. She never thought that the criminals had been subdued and she could be hit by stray bullets.


    However, recalling yesterday''s task, Qin LAN still felt that her heart beat too fast and was afraid of the ferocity of those criminals.


    At that time, after the temporary command group issued an ultimatum to the criminals who occupied the refuge, the criminals chose to open the door, and everyone thought that the task was over.


    The criminals who came out of the door were all subdued, handcuffed and ready to be sent back to the city in the prison car, but no one expected that one of them had hidden explosives and detonated.


    Two close special police members were affected by the explosion and died on the spot. A dozen other special police members and armed police soldiers were also affected and injured in different degrees.


    After the explosion, a group of prepared criminals rushed out of the shelter, snatched the guns in the hands of the injured special police and the armed police, and attempted to resist tenaciously or even counter attack.


    There was a fierce gunfight between the two sides, and even the revolver gun, which was not intended to be used, roared and fired at the criminals.


    Qin LAN, as a sniper in charge of support, naturally has the responsibility to fight. In fact, she should be the first person to find the problem, because she saw the action of the criminal pulling the detonator from the sight of the sniper gun, and pulled the trigger at the first time to kill the criminal.


    But when she pulled the trigger, it was too late. Although the criminal was killed, the detonator was still pulled.


    Although the gunfight didn''t last long, and the criminals were quickly killed at the gate of the shelter, a stray bullet still hit Qin LAN in the shoulder.After the end of the battle, all the wounded were sent back to the urban hospital for rescue at the first time. However, three of the wounded were too seriously injured to be rescued, and five of them were still being rescued.


    Of all the people, Qin LAN, who was hit by a stray bullet, was the least injured.


    This made her feel lucky and afraid, and she could not help blaming herself. If she had shot even one second earlier, it might not have led to such tragic consequences. A total of five people died, five were seriously injured, and more than a dozen were injured in different degrees. This can be said to be the heaviest loss suffered by the police system since the founding of the people''s Republic of China.


    The thought of her comrades in arms dying and injured because she shot slowly makes Qin LAN feel very sad. The pain of the wound on her shoulder also affects her, so that she hasn''t closed her eyes since she took out the bullet on her shoulder after the operation last night.


    Just staring at the lamp on the ceiling, my eyes are full of blood, but my mind is reappearing the scene of yesterday.


    If you can shoot a second earlier, if you can find the abnormality earlier, then many people will not be sacrificed and injured!


    This idea is in Qin Lan''s mind, which makes her recall the scene of yesterday again and again. She is trying to find out the evidence that can convince her that she didn''t shoot too late, and the "evidence" that she didn''t find in time.


    But this did not play any role, but deepened her remorse and remorse, so that she was almost engulfed by it, until Chen Xin broke into the ward, which pulled her out of the constant cycle of memories.

 Chapter 170

    "Ah LAN, how are you? Are you all right? " Seeing Qin LAN lying on the bed with a dejected and red eyes and a thick bandage on her body, Chen Xin hurriedly asks her what she cares about.


    However, seeing Qin LAN just lying there with her eyes still open, Chen Xin was relieved, and finally let go of her worries.


    After all, Qin LAN didn''t seem to be short of arms and legs at this time. Besides the bandage on her shoulder, she didn''t have any obvious scars, and she didn''t feel unconscious.


    It just seems that the mental state is very bad, and this is not a particularly serious situation, good cultivation can recover.


    "Ah Xin..." See Chen Xin appear, Qin LAN called his name, but the voice is particularly hoarse and dry.


    Looking at Qin Lan''s nearly cracked lips and listening to her hoarse voice, Chen Xin doesn''t need to think about it to know that she hasn''t drunk water for a long time, so he quickly picked up the cup on the bedside table and poured a glass of water for Qin LAN from the kettle.


    Carefully holding Qin Lan''s neck and feeding water to her mouth, looking at Qin Lan''s thirsty appearance, Chen Xin comforted her: "drink slowly, don''t worry, there is something else."


    However, after drinking the water in the cup, Qin LAN shakes her head and stops Chen Xin from feeding her water again.


    Seeing this, Chen Xin also put down the cup and sat down at the head of Qin Lan''s bed. Looking at her haggard appearance, he touched her forehead and asked with concern: "what''s the matter? How do you make yourself like this? It''s not like you at all! "


    "Ah Xin..." Feeling Chen Xin''s gentle comfort to herself, Qin Lan''s emotion that she had been accumulating since yesterday suddenly burst out. She called Chen Xin and cried.


    Hand wipe Qin LAN face tears, looking at her cry so sad, Chen Xin did not stop her, just gently stroked her forehead, comfort her: "it''s OK, it''s OK, just cry out."


    Qin LAN cried for a long time, as if tears could not stop.


    Until Chen Xin felt that her crying would hurt her body, it stopped her from crying. He coaxed her and tried to figure out what was going on.


    After crying, Qin Lan''s emotion seems to be released. At this time, she can finally restrain her emotion, sobbing and intermittently telling Chen Xin what happened.


    "It''s all my fault. If I fired that shot earlier and I was more decisive, those brothers would not have died!" After explaining to Chen Xin what happened, Qin LAN has a tendency to cry. She is always blaming herself, regretting her own mistakes and thinking that she caused all this.


    Listening to Qin Lan''s words, Chen Xin didn''t know how to comfort her. She could only wipe away the tears on her face quietly and gently, and said to Qin LAN, "don''t be like this, ah LAN, you don''t want to, who knows that things will turn out like this? And even if you shoot in time, with the madness of those people, they must have other means. You can''t blame for this. "


    "Why don''t you blame me? If I had shot earlier, I would have stopped the criminal from pulling the detonator, and the comrades standing beside him would not have died! " Qin LAN roars at Chen Xin, venting her dissatisfaction with herself.


    "How can I blame you? You can''t have known in advance that the criminal had gunpowder and detonator on him! You have responded in time. You can only say that the criminals are too vicious. You should blame the criminals, not you. " In the face of Qin Lan''s emotional collapse, Chen Xin can only try to appease her: "and even those who sacrifice, they certainly don''t want to see you look like you blame yourself. If you feel sorry for them, shouldn''t you cheer up and try to bring those criminals to justice? "


    Listening to Chen Xin''s words of comfort, Qin Lan''s mood finally eased and gradually subsided.


    Although still feel remorse for themselves, but did not continue to shout and cry.


    But after the mood eases down, the thick tiredness surges up, Qin LAN quickly closes her eyes and falls asleep.


    Looking at Qin Lan''s frowning with her eyes closed, Chen Xin was distressed, but he didn''t do anything more. He just covered her with a quilt and sat on the chair beside the hospital bed, intending to guard her.


    However, when Chen Xin was guarding Qin LAN, a hand suddenly pressed on his shoulder.


    Chen Xin quickly looked back, but saw that Hongrui was standing behind him, with a finger pointing at him and making a "hush" gesture.


    Seeing that it was Dr. Hongrui, Chen Xin didn''t scream, but asked quietly, "Dr. Hongrui, when did you come?"


    "I''ve been here for a while, when you told her not to cry." Dr. Hongrui explained and gave a smile to Chen Xin: "I was supposed to help her with psychological counseling, but I didn''t intervene because you did a good job. Thank you for saving me a lot. "


    "No matter what doctor Hong says, ah LAN is mine..." When Chen Xin said this, he suddenly got stuck and shook his head with a smile. Then he continued: "when she comes across this kind of thing, within the scope of my ability, I can''t stand by."While saying that, Chen Xin looked at Qin LAN on the hospital bed and sighed.


    Who can think that she who is always strong will be so vulnerable? Not long ago, she was comforting herself not to break down.


    Thinking of this, Chen Xin sighed again.


    Listening to his continuous sigh, Hong Rui shook her head, patted Chen Xin on the shoulder and whispered to him, "let''s go out and have a good rest here."


    Hear red Rui say so, Chen Xin also nodded, followed red Rui to walk out of the ward together.


    When they come to the corridor outside and close the door of the ward, Hong Rui and Chen Xin speak in a normal voice.


    "I didn''t expect to see you again, Dr. red. I haven''t said thank you for last time." Chen Xin is polite to Hong Rui, but he is also concerned about Qin Lan''s situation: "how is ah Lan''s situation? Is it serious? "


    "It''s not serious, but the psychological trauma may be very serious. I''m afraid it''s hard to cure for a while. It takes time for her to walk out slowly." Red Rui shook her head, did not say any complex professional terms: "encounter this kind of thing, she must also feel bad, this time more care to accompany her, what she needs most is the company of family and friends."


    "I see. I''ll take care of her." Chen Xin nodded solemnly.

 Chapter 171

    After a deep sleep because of fatigue, Qin LAN wakes up because of the pain of the wound on her shoulder.


    "Ah LAN, are you awake? Are you hungry? There''s porridge here. I borrowed a thermos bucket specially. It''s still hot. " Seeing Qin LAN open her eyes, Chen Xin cares about her state for the first time.


    Qin LAN takes a look at Chen Xin. It seems that she wants to get up, but it''s really inconvenient for her to hang a hand. Moreover, when she moves, she obviously pulls the wound, which makes Qin Lan''s face show a painful expression.


    "Don''t move, don''t move! Remember, I''ll help you! " Chen Xin quickly and carefully hold her down, which will shake up the bed, so that Qin LAN can sit on the bed.


    For Qin Lan Sheng a bowl of still warm porridge, Chen Xin sat to the bedside, with a small spoon scooped a spoon, gently blowing, stretched to Qin Lan''s mouth: "eat something, I asked the doctor, they said you sent from yesterday did not eat, must be hungry."


    Qin LAN looks at the hot porridge fed in front of her. Chen Xin says that, and she really feels hungry. So she opens her mouth and asks Chen Xin to feed the hot porridge to her mouth.


    However, as soon as the porridge came into her mouth, Qin LAN tasted the difference and asked Chen Xin, "is this a Xin you cooked? You are the only one who likes to put salt in white rice porridge. "


    "Seasoning, seasoning!" Seeing that Qin LAN still has the spirit to discuss the taste of white rice porridge with himself, Chen Xin smiles and scoops up a spoonful of porridge to feed Qin LAN.


    While eating Chen Xin''s porridge, Qin LAN can''t help but ask curiously: "a Xin, where did you come from? Can''t buy rice now? "


    "Have you forgotten the upland rice I planted in the greenhouse? The rice has been harvested. This is my own rice. " Chen Xin explained to Qin Lan that she seemed very happy to see that she didn''t continue to dig into the corner, so she continued to talk about rice: "after shelling, there is no pure white. It''s just a simple smash, which can be regarded as germ rice. Ah LAN, you are injured. Now you need to eat something nutritious. "


    Hearing Chen Xin say so, Qin LAN looks suddenly dark, looks at his shoulder, and thinks of his former comrades in arms.


    But after a sleep, Qin Lan''s spirit is much better, and she doesn''t fall into remorse and regret as before. Although she is still very sad, she has recovered from the previous shock and collapse.


    But her heart is not so easy to eliminate for this matter.


    Chen Xin naturally saw this, so while continuing to feed Qin LAN with porridge, he also asked her what he thought when she was asleep: "a LAN, you told me before that it was a criminal who pulled the explosives on her body that caused such a big injury, but it doesn''t make sense!"


    "Doesn''t it make sense? What makes sense? " Qin LAN looked at Chen Xin and frowned. She didn''t understand what he meant.


    "When you say that criminals occupy shelters, I believe that in the last days, there will always be some people who want to make trouble when they feel that the state and the army can''t deal with them and can start their own business. But these people are just some careerists who can''t get on the stage or the second disease in the brain. How can they have the charm and executive power to make people carry explosives to suicide attacks? " Chen Xin didn''t figure this out before. At this time, he asked Qin LAN about his doubts.


    Suicide attacks are not uncommon. During the Second World War, the Japanese kamikaze and JuShui special attack, the soldiers who knew they would die on the battlefield, the fanatics who were brainwashed by religion and carried out terrorist activities


    These examples are all suicide attacks, but all of them are supported by strong spiritual thoughts. No matter good or bad, only the most determined people can make such attacks and use their lives to kill the enemy and opponents.


    But the firm will needs the spirit and thought as a guide, without systematic training, it is difficult to establish enough firm spiritual belief.


    However, how can a group of criminals have such firm thoughts and will?


    Knowing that he would die, even if there were no bones left, he still firmly chose the suicide attack, detonated the explosives tied to his body, and even made Qin LAN, a sniper, have no time to react. You can imagine how determined the other party is when doing this.


    They are not Japanese soldiers brainwashed by the education of the Communist Party of China and the spirit of Bushido. They are not terrorists who have been turned into madmen by religious fanaticism. However, they are just a group of criminals in the ordinary third tier cities of Yanguo. It is their normal to be greedy for life and afraid of death. How can they be so fierce and fearless of death?


    "This..." Chen Xin said that, Qin Lan also realized that it was not right. The criminals who occupied the refuge behaved abnormally.


    In addition to the criminal who detonated the explosives, the criminal who later rushed out of the shelter with the intention of counterattack was also very resolute and resolute. Even the action of grabbing guns and counterattack was very well-trained. If they didn''t focus on machine gun shooting, they might even cause greater losses.


    None of this can be done by a group of ordinary criminals with temporary intention. Only those who have undergone strict training and mental control can do it.


    "You mean they''re terrorists?" Qin LAN looked at Chen Xin and understood what he meant, but she was also puzzled: "but this is the central part of Yan country, not the Middle East or South America in war! Where are the terrorists from? ""I don''t know. It''s something that your police should look into, isn''t it? But you have to admit, it''s just freaking out Chen Xin smiles and continues to feed Qin LAN porridge.


    He knows that Qin Lan''s attention has been transferred from regret and self blame, and he begins to pay attention to the abnormality of this matter, which also achieves his goal.


    "Ah Xin, since you have discovered this, have you not told anyone else?" After Qin Lan''s thinking was guided by Chen Xin, his professionalism began to show itself: "since I found a problem, I should report it to the team leader as soon as possible!"


    Qin LAN wants to get up and go to Uncle Ding to talk about it.


    Chen Xin quickly held her down and stopped her reckless action: "don''t worry about this matter, Alan. I can see the problem. I don''t think uncle Ding can''t see it. Besides, you have injuries on your body now. If you have anything to do, you have to take care of them first. Even if you want to send a message, I can help you pass it on."


    "Ah Xin, please call the team leader as soon as possible! There''s a call to the SWAT team at the hospital! " Qin LAN hears Chen Xin say so, hasten to urge Chen Xin.


    Just when Chen Xin pacifies Qin LAN and is ready to make a phone call, Ding Ning''s voice suddenly comes from the door: "what''s the matter to call my father?"

 Chapter 172

    "Xiaoding!" Chen Xinchong Ding Ning said hello: "how did you come here?"


    "I heard that sister Lan was injured. I''ll come and have a look. What were you talking about? What do you want to tell my dad? " Ding Ning, while greeting Chen Xin and Qin LAN, is also concerned about what they have just said.


    Chen Xin explained to Ding Ning, and then said what he had just speculated: "when a group of ordinary criminals are hit by special police and armed police, they can resist at most. They will fight hard only when they are in the most desperate situation, and most of them are dogs jumping from the wall.


    But these criminals are obviously not. They are obviously premeditated and planned to launch suicide attacks. Even their behavior of occupying the refuge itself is very suspicious. They can''t be unaware that occupying the refuge will lead to the encirclement and suppression of the police, the armed police and even the army. "


    "It can also be too stupid to know." Ding Ning listened to Chen Xin''s analysis and added a possibility.


    Chen Xin nodded his head and affirmed Ding Ning''s supplement, but said: "but those stupid people can''t do such things as suicide attack and decisive charge, unless they are all idiots. They are so stupid that they don''t even know how to die."


    Speaking of this, Chen Xin turned to Qin LAN and asked her, "a LAN, do you think those people are idiots?"


    Qin LAN seriously recalled the criminals she saw through the sight glass, shook her head and said: "it''s not like a fool, it''s like..."


    It has to be said that those faces that have been deeply engraved in her mind are only ferocious and fierce, without any foolishness. What she insists on is that those people are very fanatical.


    "Their goal is very clear, their action is also very decisive, even in the fierce battle, they are not influenced by the dead accomplices, and their fighting will is very tenacious, which is not like a group of bewitched fools or ordinary criminals." In calm time, Qin Lan''s brain as a sniper is still very easy to use, and quickly analyzed the key elements.


    Ding Ning listen to Chen Xin and Qin Lan''s analysis, look dignified, can''t help nodding his head and said: "if it''s really like sister Lan''s analysis, then this matter is to quickly tell my father."


    As a policeman, Ding Ning can certainly understand the seriousness of the incident, and she can''t be unaware of what happened yesterday when there were more than 20 casualties.


    Since both Ding Ning and Qin Lan said so, Chen Xin didn''t insist on his own opinion, and felt that he really wanted to tell Uncle Ding about it.


    The hospital has a telephone. Although the mobile phone has been unable to use because of the disconnection of satellite and base station, the traditional wired telephone is still playing a role.


    After listening to Chen Xin''s analysis, uncle Ding also attaches great importance to this matter.


    After all, it was more than 20 casualties. This is the first time in the history of the city. No matter the Municipal Bureau, the municipal government or the armed police, they were very angry about this. The municipal government even ordered a thorough investigation into this matter.


    A special investigation team has been set up to find out why terrorist activities of such a bad nature occur. As the captain of the special police team, uncle Ding is also a member of the investigation team.


    Chen Xin''s analysis is timely. Although the investigation team has collected many clues, Chen Xin''s analysis still gives them a new idea.


    After thanking Chen Xin, uncle Ding also asks him to tell Qin LAN on the phone that she can take good care of her injury, have a good rest, and don''t have any burden. The team grants her a month''s long holiday and sends Ding Ning to take care of her.


    Hang up the phone back to the ward, Chen Xin can not help but some strange, this time to give Qin LAN a month''s holiday, but also let Ding Ning to take care of her, this is no problem?


    With such doubt, Chen Xin tells Qin LAN and Ding Ning about it. After they listen, they look strange.


    "It''s really strange. It''s no problem to get hurt and have a holiday, but why does my father want me to take care of sister LAN?" This is the most puzzling part of Ding Ning, arrange to take care of the injured Qin LAN, what is the intention?


    Qin Lan also feels a little strange. Although she has been injured for 100 days, it''s no surprise that she has been shot for a holiday. However, it''s better to give herself a month''s holiday in such an obviously eventful autumn.


    Although she was hit in the shoulder by a stray bullet, she will return to normal in a week or so according to the doctor''s expectation after taking out the bullet.


    Even if they are worried about their own psychological problems, or have to carry out relevant investigations, a month''s time is too extravagant at this time of employment. Moreover, uncle Ding, who is the captain of the special police force, has sent Ding Ning to take care of her, which makes things more suspicious.


    Although Ding Ning can''t say that she can''t take care of others, if someone really takes care of Qin LAN, it''s not that there are no people who have nothing to do in the shelter. Hiring someone is more reliable than Ding Ning.


    "Don''t think so much. Since uncle Ding said he would let you off, you should cultivate yourself first." Chen Xin can''t tell why. He is trying to persuade Qin LAN to take good care of her.


    Because Ding Ning is temporarily sent to take care of Qin LAN, Chen Xin doesn''t have to stay with Qin LAN all the time, so he can go back to his refuge to deal with things.After all, at this point in time, the vegetables in Chen Xin''s shelter need to be replanted, and the rice seedlings that are already in the process of seedling cultivation need to be transferred to the fields in time. There are not many things to do.


    After leaving the hospital and returning to his refuge, Chen Xin did not forget to say thanks to Li Yulong who sent him back: "thank you very much this time. If it wasn''t for Bruce Lee, you''d lend me a car, my own car would not be able to travel to and from the city frequently in this weather."


    Before, Chen Xin took advantage of Qin Lan''s sleeping time to cook the porridge in the hospital. He came back from the city to the shelter and took the rice he had planted. He was able to travel to the city in a short time because of Li Yulong''s generously lent modified RV. Even the porridge itself was cooked in the kitchen of his fully functional RV.


    Chen Xin also envies and appreciates such a convenient saloon car. He thinks that if he wants to transform the car, he doesn''t care what style he adopts. As a living cabin, the function of the car must be complete, and there must be a kitchen.


    "Brother Chen, you''re welcome. I''m worried about sister Qin''s accident. It''s just borrowing a car. It''s nothing." Although Li Yulong is a businessman, he seems to be brother enough in this kind of thing, and he is not reluctant or stingy.


    Chen Xin thanks him again, but when he says thank you to Li Yulong, the system that hasn''t had any reaction for a long time suddenly jumps out a prompt: "people in other people''s shelters die, and they get survival - 2 every day."

 Chapter 173

    Someone''s dead? Looking at this tip, Chen Xin could not help but feel very surprised.


    "Other people''s shelter personnel died" obviously means that he received the oxygen generator and ground source heat pump equipment provided by him, which gave him a shelter for survival.


    In fact, the scope is very narrow before the official shelters are settled.


    Doctor, Li Wensheng, Mo Qingyan They are all friends in the survival group.


    So whose shelter is dead? So far, Chen Xin has replaced eight oxygen generators and two ground source heat pumps for group friends, with a total of 3400 survival points, one-time survival points and + 34 points a day.


    But now it''s + 32.


    Will the increase that has been gained decrease with the death of people? Chen Xin secretly wrote down this point, at the same time, he was more concerned about who died in the shelter.


    It''s just that it''s not easy for him to ask openly. It''s impossible for him to turn on the radio and shout "who died in the shelter?"?


    After thinking about it, Chen Xin can only write down the incident, and plans to ask which group of friends had an accident when he makes routine communication.


    Apart from this emergency, there is nothing else to disturb Chen Xin''s arrangement.


    After cleaning up the empty planting board in the greenhouse, putting new seeds on it, and checking the rice seedling raising and the fish in the sink, Chen Xin finished the circle.


    After kneading his hungry stomach, Chen Xin also began to prepare dinner. This evening, he plans to go to the city to see Qin LAN again and send her dinner by the way.


    Although the food in the hospital is not bad, there are porridge and other vegetables, but the rice is obviously old rice stored in the granary, and it is white rice after being refined. In terms of nutritional value, it is worse than germ rice or brown rice.


    It''s not that Chen Xinfei insists that germ rice is better than white rice, but in the current environment, the food in the hospital is not bad, and it''s only relative to the standard food in other refuges. Although it''s not bad, it''s just the ordinary level before the disaster.


    For the wounded like Qin LAN, being able to eat more nutritious food will also help her recover.


    He took some rice from the food storeroom, cut a piece of Jinhua ham, and took out a piece of previously frozen fish from the refrigerator, as well as some stored carrots. After thinking about it for a while, Chen Xin took a can of tuna, and then came out of the storeroom to prepare dinner.


    The rice husk is removed, the rice bran is blown away, and then the rice bran is washed to make porridge. Chen Xin then deals with other ingredients.


    The frozen fish came from the trade with Li Wensheng before. Chen Xin didn''t eat well, so there were still some left. The live fish in the greenhouse were used for breeding. He won''t move yet, so there were only frozen fish.


    Fortunately, these fish have already been disposed of, and Chen Xin has cut them in sections, so they can be used for cooking only by thawing.


    Chen Xin plans to stew a pot of fish soup. As a high protein food, fish is very good for wound recovery.


    "It''s a pity that there is no ginger and garlic, so we can only stew it with wine." Chen Xin can''t help sighing. Fish has a fishy smell. If you do it normally, you need ginger and garlic to go fishy. But now without these things, you can only cook some wine to go fishy.


    Fortunately, it''s stew. Chen Xin doesn''t worry that wine will affect Qin Lan''s wound recovery.


    Put the thawed fish into the pot and fry it for a while, then cook a little rum along the edge of the pot. After smelling it, Chen Xin felt relieved to put the fish into the stew pot and add water to start stewing.


    As for Jinhua ham and carrot, they should be stewed together in the soup.


    Jinhua ham is fresh and seasoned, and carrot is rich in nutrition. It is a good auxiliary material for fish soup.


    While thinking about this, Chen Xin opened the tuna can and smelled it before adding it to the porridge he was cooking.


    White rice porridge has no flavor, and adding a little tuna can be regarded as seasoning.


    After everything was ready, Chen Xin warmed up a shelter food for himself as his supper.


    After a quick meal and a simple bath, the soup and porridge were stewed. Chen Xin packed the soup and porridge separately with the thermos bucket that he had brought porridge to Qin LAN before, and stored the rest in a sealed fresh-keeping box. Chen Xin then drove his car to the city with the thermos bucket.


    Considering that the road is difficult to drive and there is no refitted RV of Li Yulong, Chen Xin hesitated for a while and then decided to upgrade his SUV.


    However, because of the temporary intention, and the constraints of materials and survival, Chen Xin only spent 500 points to improve the tire and the traffic capacity of the vehicle, but did not make a major transformation.


    The SUV with modified tires and improved traffic capacity runs much smoother. Even when it encounters a crosswind on the bridge connecting the urban area, Chen Xin''s car just shakes, and there is no sideslip.


    Driving steadily to the hospital, Chen Xin comes to the ward with a heat preservation bucket. Ding Ning is chatting with Qin LAN.The content of their conversation is undoubtedly what Chen Xin analyzed before. They are still discussing who can be identified as terrorists.


    Ding Ning guessed that it might be a member of some terrorist organizations, but Qin LAN didn''t think that there could be any terrorist organizations in the hinterland of Yan state, and that there could be such a big stir. Instead, he thought that it might be some cult.


    After all, the only thing that can make people brave and fearless of death is faith, but some beliefs urge people to work hard, and some beliefs can only make people blind and fanatical.


    In today''s eschatological environment, the refuges are relatively closed, which can be said to be a good soil for the spread of cults. If the city government and refuges had not strictly controlled this, I''m afraid all kinds of doomsday heresies would have spread long ago.


    Even so, Qin LAN has already seen all kinds of absurd or ignorant, even evil and cruel cults in her previous duty.


    However, she does not think that these cults, which have sprung up like mushrooms, can have such organizational and executive power, and can make believers believe enthusiastically, which is the basic skill of the spread of a cult. However, it is by no means what ordinary cults can do to make believers launch suicide attacks so fearlessly and well-trained.


    Moreover, it is not possible to cultivate such a dead man like believer overnight.


    So Qin LAN thinks that this is probably a cult that has existed for a long time. It''s just that they have been hiding under the water all the time before, but the coming of the end has exposed their ambition.

 Chapter 174

    Although Qin LAN has a lot of speculation about the identity of those criminals, she can''t do anything about it when she is on holiday. Now she can only recuperate in the hospital.


    Fortunately, there was Ding Ning with her, but she didn''t have nothing to do.


    And Chen Xin still gives her food every day. Although there are not many available ingredients, Chen Xin still tries his best to make food for her, so that she can supplement more nutrition.


    This incident may have had only so much impact on Qin LAN and Chen Xin, but it caused a stir in the whole urban area and the counties and cities under the jurisdiction of the urban area. Even the provincial government was alarmed. An urgent investigation team was sent to the city government to conduct joint investigation with the investigation team of the city government. At the same time, all the refuges in the urban area were screened.


    No matter big or small, official or private, all shelters must be inspected by the joint investigation team. For this reason, not only the city''s Armed Police and special police are fully mobilized, but the provincial government''s investigation team has also transferred an army from the provincial capital.


    Although there are only two companies of soldiers, they are real combat forces. Different from the armed police and special police, which are internal security forces, they are military forces used for external operations. What the use of the army represents is that the significance of this matter has become quite different.


    If it''s just the armed police and the special police, it can be said that this is a contradiction among the people. These people are not foreign enemies.


    But once the army is used, it means that the criminals who made this incident no longer belong to the ranks of the people, but to the enemies outside the masses of the people.


    This is just like the riot in Xiangjiang before the disaster. Although Yanguo has garrisons in the local area and the armed police forces in the next city, it is the local police, not the garrison, who are responsible for handling the incident.


    This is not only a political consideration caused by the threat of foreign hostile forces, but more importantly, these people are still regarded as part of the people, not as enemies of the country.


    In the state of Yan, it has always been a national policy for the army to be external and the police to be internal.


    Although the army will also be deployed to rescue and rescue or help the people in all kinds of disasters, military operations are only aimed at foreign enemies. In the history of Yan state, the muzzle of the army has never been aimed at the people.


    But now that the provincial investigation team has transferred troops, the nature of the incident is undoubtedly quite different.


    At the request of the joint investigation team, all the shelters were inspected, the identity and origin of the people in the shelters were screened by special personnel, the suspicious people were investigated and inquired, and the relevant responsible persons were also stressed the seriousness of the matter.


    It can be said that for a moment, the whole city has entered a state of panic, shrouded in a serious and tense atmosphere.


    In such an atmosphere, the black market, which was originally formed spontaneously in the urban area, naturally could not go on. It was immediately raided by the special police force, and no private transactions were allowed, so as to avoid providing materials for potential criminals.


    And Li Yulong''s plantation was temporarily suspended after the small shelter was checked. Although Li Yulong was not regarded as a suspect with the endorsement of the city government, the project was put on hold for the time being. I''m afraid it will not be able to resume operation until a result of the investigation.


    This is undoubtedly a huge blow for Li Yulong, who is determined to do a big business. His just started business has suffered such setbacks. Although it can not be said that he has failed, it also makes him feel depressed.


    "Brother Chen, what''s the matter with you? Who am I provoking? " Li Yulong is complaining to Chen Xin. In this matter, he can only find Chen Xin to complain.


    "It''s just a disaster. You''re just affected by it." Listening to Li Yulong''s complaint, Chen Xin is not in a good mood: "even my shelter has been searched by special police. Your project has been stopped rather than cancelled. Thank God."


    Hearing Chen Xin say so, Li Yulong felt even more depressed: "it''s true to say so, but it''s really unpleasant!"


    "If you don''t like it, go and find out what''s going on and find out those people." Chen Xin looked at Li Yulong and said to him seriously, "your family is black and white in this city. Can''t you find out about it? As long as you can find out who did it and put clues in front of the joint investigation team, I believe they will restart your project soon. "


    Since Li Yulong''s father was a well-to-do businessman in the city before the disaster, and he also worked in the catering and hotel industry, he naturally had a very deep personal relationship in the city, so it''s easy to check some things.


    But after listening to Chen Xin''s words, the expression on Li Yulong''s face became more depressed.


    "Don''t mention it. I told my dad to find a relationship to check this, but he told me not to get involved. The project will stop when it stops." This is the reason why Li Yulong is most depressed.


    When his business was shut down, his father not only didn''t help him find a way, but also told him not to get involved, which undoubtedly made Li Yulong''s enthusiasm empty, just like a punch in the air.


    Hearing Li Yulong say so, Chen Xin frowned, which is very interesting.His son''s business has been affected. Li Yulong''s father not only doesn''t help Li find a way out, but tells him not to get involved in this matter for the time being. This is not because Li Yulong''s father thinks it''s too dangerous to cause trouble, but also knows what he doesn''t want his son involved in.


    What kind of idea does Li Yulong''s father belong to?


    I think it''s possible that the water is too deep. Although Li Yulong''s plantation project has been affected, it''s not too deep. As long as we don''t take care of it, it''s nothing.


    However, Chen Xin always feels that this matter is not so simple.


    However, it''s a matter between father and son. Chen Xin doesn''t want to get involved in it, so he digs off the topic and talks about other things with Li Yulong.


    "Brother Chen, do you know? A few days ago, there was an accident at the family of the "doctor" in the group. Because of the lack of heating equipment in his family, his parents were frozen to death a few days ago. " Now that he has digged off the topic, Li Yulong naturally doesn''t mention it any more. He turns to what happened among his friends before.


    "Well? The doctor''s parents are dead? " Hearing what Li Yulong said, Chen Xin suddenly remembered the system prompt he had received before. It seems that he should have died at that time.


    It''s just the doctor''s parents. Why do they die? In this weather, although the shelter of his family is simple, it has been cooling down for some time. How can it freeze to death at this time?


    But thinking of his parents'' faces when he went to the doctor''s last time to deliver things, Chen Xin could not help shaking his head and did not want to go into the cause.

 Chapter 175

    Chen Xin has little to do with other people''s lives. What he needs to worry about now is his own life.


    Chen Xin''s original plan to upgrade the shelter was also affected by this incident. Chen Xin''s original plan to collect materials through Li Yulong''s trading market was temporarily destroyed with the suspension of the trading market and the plantation. In the short term, the material trading on the side of the SWAT team will not be able to do so.


    After all, the trading market project has been suspended, and the special police force has to put the police force into the investigation of this incident. The material transaction with Chen Xin can only be maintained in the exchange of basic living materials.


    This makes it impossible for Chen Xin''s original refuge upgrade plan to continue in a short time.


    Although the survival settlement has been made after the ground source heat pump unit on the side of the special police team has run smoothly, which makes the survival reserve of Chen Xin''s head close to five figures, and the daily survival has also exceeded 100. As long as he has accumulated more time, it will be enough to upgrade the refuge with survival, but Chen Xin still doesn''t want to upgrade in this way.


    On the one hand, it costs too much, on the other hand, a single upgrade scheme can not meet the needs of Chen Xin.


    During the settlement of survival on the other side of the SWAT team, Chen Xin also found out that according to the rules set by the system, the maximum survival he can obtain at a single refuge or settlement is 5000 points, and the maximum daily survival he can obtain at a time is 50 points.


    This obviously limits Chen Xin''s idea of quickly obtaining a large number of survival points in a short time, and then directly upgrading the refuge with survival points.


    Maybe you can choose an upgrade scheme first, and then make subsequent adjustments, but if you can, Chen Xin still hopes to upgrade the whole refuge at one time.


    Therefore, because of the shortage of materials, Chen Xin had to shelve his plan to upgrade the refuge and put his energy on other things.


    For example, the upgrading of their own cars.


    In recent days, he frequently goes to and from the urban area to deliver meals to Qin LAN. With the increasing demand for cars, Chen Xin also has more requirements for his own car. Therefore, upgrading the car has become his immediate priority.


    However, this is not a big impact. After all, the vehicle renovation was the top priority in his priority list. Now it''s just a move back on the overall upgrade of the refuge, making it the top priority.


    Previously, in order to go out, Chen Xin had upgraded the wheels to improve the traffic capacity of the tires on the snow road.


    But this is only the most basic upgrade, and can''t change the vehicle performance completely.


    Although it is enough in the current situation, Chen Xin wants more.


    In the past, the modification of the tire only made the ordinary snow tire more grip, and adjusted the chassis height and suspension system. But if you want to continue to improve the performance and ride comfort, you must upgrade more things.


    For example, the structure of the chassis.


    Now Chen Xin''s car is still a wheeled chassis, with the advantages of low fuel consumption, light weight and good mobility, but its traffic capacity is worse than that of a tracked chassis.


    Although the crawler chassis is more bulky and has higher fuel consumption, it has stronger carrying capacity and can drag a heavier car body.


    And the driving force of the crawler chassis is larger, and the ground pressure is smaller, so the off-road performance and stability are good, and the climbing ability is large, which is more suitable for the traffic under the complex road conditions of the wild ups and downs.


    Especially when driving in the snow, the wheel chassis is prone to tire falling into the snow, while the track does not have such trouble. The track with larger grounding area can make the vehicle run smoothly on the snow surface, without causing the wheel falling into the snow.


    Therefore, for Chen Xin, he would like to replace the chassis of the SUV with crawler, and upgrade it from SUV to ATV.


    However, tracked chassis has many advantages, but energy consumption is a key point that Chen Xin can''t avoid. After all, there is no engine with high horsepower that can''t move the tracked chassis forward, and high horsepower also means high fuel consumption.


    "So we have to go around nuclear power." Chen Xin looked at the design sketch he had painted on his computer and felt that he still wanted to give nuclear power to his car.


    Because only nuclear power can meet his needs. After all, if the crawler chassis is replaced, the fuel consumption is also amazing.


    As for nuclear power, it''s not high technology. Although many people talk about nuclear discoloration and directly associate nuclear with radiation, they always think it''s very dangerous. However, we have to say that with the current level of human science and technology, we can use nuclear energy cleanly and efficiently.


    Moreover, the sustainability and stability of this kind of thing are also very reliable. The nuclear power lighthouse built in the pre sovya era is still in operation today, but the radiation leakage only occurs due to the long-term lack of maintenance and aging of the equipment.


    Therefore, in history, those who failed to make a decision on nuclear bombs not only made nuclear powered tanks, which are four track monsters, but also used nuclear bombs to repair reservoirs and plug oil field fires.And it''s not complicated to put nuclear power on the vehicle, just need a radioisotope thermoelectric generator.


    The principle of this kind of thing is to use the radiation with heat energy released by radioactive substances in the decay process to convert heat energy into electric energy in thermoelectric elements.


    Radioactive materials are very stable in the decay process, and the released energy and speed are not affected by the temperature, chemical reaction, pressure and electromagnetic field in the external environment. Therefore, radioisotope thermoelectric generator is famous for its strong anti-interference and accurate and reliable operation.


    Another characteristic is that the transmutation time is very long, which determines that the nuclear battery can be used for a long time.


    Of course, Chen Xin doesn''t have a nuclear battery in his hand, and he has no place to buy it, but he has a system, which means he can upgrade himself.


    If you want to make a nuclear cell, you need to make a long half-life isotope into a charge, and then wrap it with thermoelectric elements. For safety reasons, you may also wrap it with a layer of lead to prevent radiation leakage.


    But the upgrade of the system is not so troublesome. Chen Xin only needs to prepare long half-life isotopic materials, thermoelectric components and lead to upgrade the car battery on his SUV to a nuclear battery.


    Of course, without these things, it''s no problem to upgrade directly with survival points.


    After carefully considering various advantages and disadvantages, Chen Xin decided to upgrade a nuclear battery directly from the survival point, and then consider the issue of obtaining isotopic materials.


    After all, isotopes are controlled materials in Yanguo. They are not as easy to get as thermoelectric elements and lead. He can''t get them directly.


    However, if there is a nuclear cell as a sample and says that he can make a nuclear cell, Chen Xin still hopes to get some isotopic materials.


    Thinking of this, Chen Xin picked up a wrench and a driver from the workbench and decided to first remove the car battery from his car and upgrade it to a nuclear battery.

 Chapter 176

    It is a very simple thing for Chen Xin, who is already familiar with how to use the system upgrade, to upgrade the car battery to a nuclear battery.


    Remove the car battery from your SUV, open the system interface, invest in survival, and click upgrade.


    The 1000 survival point disappears and the green light flashes. The car battery made of black-and-white plastic has become a cylindrical nuclear battery with a metal shell shining green.


    Looking at this familiar shape, Chen Xin can''t help pressing his forehead. Isn''t this the battery of Titan in Titan fall?


    In the game, this thing is the driving energy of Titan''s big guy. It only needs one to make Titan''s tall humanoid fighter move, and three batteries can make it gallop freely on the battlefield and play a strong combat effectiveness.


    If it''s the kind of nuclear battery in the game, it''s very suitable to use it in vehicles.


    Titan is not only firing guns, but also moving. It also needs to support shields and release all kinds of black technology skills. Nuclear batteries can move, let alone a car.


    However, although the nuclear battery was built, Chen Xin still had to check it.


    Apart from other things, at least voltage, current and output power still need to be measured to ensure that there will be no problems in use.


    After all, if the current is too high, burn the circuit or something, it''s not fun.


    Fortunately, after some inspection, Chen Xin confirmed that this nuclear battery can continuously produce 300A current at 500V, and the actual power is 150KW, which is about 200 horsepower when converted into horsepower.


    This power is already quite large. The batteries used by the popular new energy vehicles before the disaster are basically of this power, but the power stored by those batteries is only about tens of kW ¡¤ h, which is also an important factor restricting the endurance of new energy vehicles.


    But this nuclear cell is different, with long half-life isotopes as the heat source, and its theoretical service life is more than ten years.


    Of course, if Chen Xin used to fight on a Titan as in "the fall of the Titan", a nuclear battery would not last long. However, it is obvious that Chen Xin does not need to use it so violently. He just uses it as the power source of the car.


    With the output power of 200 horsepower of this nuclear battery, driving an all terrain vehicle naturally has no problem. After all, before the disaster, the engine power of the international classic Swedish bv206 all terrain transport vehicle was only 136 horsepower, only two-thirds of that of this nuclear battery. The weight of the bv206 vehicle was 4.34 tons, and the maximum carrying capacity was two tons.


    The weight of an ordinary car is only about one and a half tons, and the output power of this battery is enough for Chen Xin to toss about.


    With the most restrictive energy problem solved, the next thing is much simpler.


    The chassis Chen Xin of course likes the crawler type, but the body Chen Xin does not want to make a hinged two car like the bv206, but wants to make an integral body.


    The advantage of hinged two car is that it is convenient to replace the rear car and realize the switching of different functional modules. At the same time, the hinged connection can also eliminate the torsional load acting on the frame, so it can improve the reliability of the whole structure and greatly reduce the requirements of the vehicle suspension system when the vehicle passes through rough areas.


    But what Chen Xin wants is not a carrier car or truck, but a more comfortable RV, which allows him to have a relatively comfortable driving and living environment in the process of driving, not to say that the car bumps like a roller coaster.


    Therefore, it naturally has high requirements for vehicle suspension and shock absorption.


    What''s more, Chen Xin planned to go back to his hometown to pick up his parents. After driving hundreds of kilometers, Chen Xin must consider stopping to have a rest.


    If he chooses two hinged carriages, if he wants to use the rear compartment when he stops for a rest, he has to get down from the cab of the front compartment to enter the rear compartment from the outside of the car body. In the current environment, naturally, the danger is greatly enhanced.


    The integrated car naturally has no such trouble and danger. It can enter the living cabin of the rear car directly from the cab.


    In addition, when he is besieged or at rest, he can enter the cab directly from the living cabin and drive away, instead of having to get off the car and go around to drive.


    Therefore, after synthesizing his own needs, Chen Xin decided to transform it into a trailer with tracked chassis and integrated body.


    Without the help of the system, it is obviously impossible for Chen Xin to transform his SUV into this kind of thing. First of all, the wheeled chassis will not become a tracked chassis, and the transmission structure and power system need to be redone, not to mention transforming the small body of the SUV into the living cabin of the RV.


    But with the system, nothing is a problem.


    However, in order to complete the transformation, in addition to the investment of survival, it also needs a lot of materials. After all, without the input of materials, the cost of survival is too high.However, there are quite a lot of materials needed to complete the transformation, even more than the materials needed by Chen Xin to upgrade the refuge as a whole.


    Of course, this mostly refers to the type, not the quantity of a single material. After all, the total amount of materials needed to transform a car can''t be compared with that of a shelter.


    Just looking at the various transformation materials displayed by the system, Chen Xin can''t help scratching his head.


    Most of the various transformation materials are automobile parts. In addition, there are cold proof materials and materials needed for the transformation of living quarters. Even Chen Xin saw water circulation devices and short wave communication radio stations in the material list.


    "To get these things..." Chen Xin copied the material list on the paper, thinking about how to get these things.


    Now, no more than before the disaster, it is no longer possible to spend money on these things to solve the problem. It can even be said that many things can no longer be obtained with money, and some even depend on relationships.


    It''s easy to say about auto parts. Li Yulong used to work as a 4S shop. Chen Xin believes that he can still get auto parts.


    As for the cold proof materials and some materials needed for the transformation of the life cabin, Chen Xin found out the list of materials he used when exchanging materials with the special police force, and saw a lot of materials he needed on it.


    But the rest, such as water circulation devices, shortwave communication stations Chen Xinyou does, but they are all important facilities installed in the shelter. Is it necessary for him to dismantle the equipment in the shelter in order to rebuild a car?


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 177

    Chen Xin doesn''t plan to dismantle the equipment of his refuge, so he has to collect additional resources or make his own parts to rebuild the vehicle.


    Fortunately, he has a workbench. He can process some parts of the materials needed for the transformation of the vehicle by himself. What he really needs to exchange and collect are some raw materials and materials that are more complicated to process and more convenient to collect by exchange.


    Among them, such as auto parts, cold proof materials, and all kinds of steel needed for vehicle transformation, Chen Xin had to exchange with Li Yulong and the special police team to get them.


    But for other materials such as shock absorbers, crawler parts and water circulation devices, he can make them by himself. What he consumes is only a small amount of survival and raw materials.


    However, most of the raw materials in Chen Xin''s reserve are prepared for the overall upgrade shelter originally planned, most of which are construction materials such as cement and steel bars, and the rest are mostly insulation boards and other things.


    There are not many high-performance steel products, such as shock absorbers and crawler parts, but only a few steel plates intended to strengthen the shelter structure.


    "So we have to collect a batch of steel!" Looking at the list of materials, Chen Xin sighed helplessly.


    Although there is a system, even the simplest metal materials can be used as raw materials, or even not metal materials, considering the cost and investment, as well as the subsequent use, Chen Xin thinks it is more appropriate to get a batch of steel.


    Fortunately, in addition to these parts that need metal materials to process, things like water circulation devices do not need to consume a lot of metal materials. Although the effect of metal materials is better, they can also be replaced by other materials.


    So Chen Xin decided to use the existing materials on hand to make everything he could, and see if he could make some lower level substitutes for those he could not, and then use the survival upgrade to make up for it.


    Although the function of system upgrade is powerful, the consumption of survival is not a small number. Although he has nearly five digit survival, according to the consumption listed in the list, if Chen Xin uses the system function to make these things without scruple, he will use at least one fifth of his survival.


    So saving or saving.


    In fact, it''s not too difficult to make water circulation device, and it doesn''t need to consume too much materials. The most important thing is the recovery of wastewater and sewage, as well as the recycling after purification.


    There is no need to worry about the recovery of wastewater and sewage. When the water circulation device is installed on the vehicle, the pipes in the water area can complete the sewage recovery. The real focus is purification treatment.


    Simple sewage purification treatment is not complicated, just using activated carbon, sand and other materials to precipitate and filter the sewage.


    However, the effect of such simple filtration is not good, and the chemical pollutants and heavy metal ions that may remain in the sewage will not be separated because of such simple filtration.


    Chen Xin has purchased portable filters necessary for survival in the wild, and has also taken apart and studied the structure inside.


    In addition to the basic sand and activated carbon filtration, the key is the filter membrane, which can effectively filter bacteria and other harmful substances in the water and make the original sewage return to the drinkable level.


    Chen Xin used this portable water purifier when he lived in the wild before. When it was difficult to find a clean water source, or when there was a lack of boiling water conditions to boil the water for drinking, this kind of filter was really a very convenient device, which could easily get clean drinking water.


    This kind of filter is used as the water purification component of water circulation device, not to mention overqualified, but more than enough.


    However, Chen Xin did not directly use his portable filter as a part to make a water circulation device, nor did he take it apart to obtain parts. Instead, he planned to make one himself.


    Saw a section of PVC pipe as the main body, and then cut off more pipes as auxiliary materials. Use the system processing function to transform the structure, turn the pipe as auxiliary material into end cover, and the rest is to fill the main pipe with filter material.


    The filter membrane material is special, Chen Xin does not have it on hand. Although it is not impossible to do it with the help of the system function, Chen Xin does not need so much trouble.


    Since we need to borrow system functions, why not upgrade them directly?


    After filling the sediment and carbon into the main body of the filter, Chen Xin compared the consumption required by making his own filter membrane and upgrading the filter directly, and resolutely chose direct upgrading.


    After all, it''s just a small thing. It costs 10 survival points to make its own filter membrane, but it only costs 15 survival points to upgrade it directly by adding a little material. In contrast, Chen Xin can afford this survival point.


    After upgrading the self-made filter to the same level as the bought portable filter, Chen Xin assembled the filter as a water purification component into the same self-made water circulation device.


    In this way, as one of the important parts of the vehicle transformation, the water circulation device is completed.


    After checking the list, Chen Xin looked at the materials and parts listed in the list and thought about what he would do next.But just as he was thinking, his radio suddenly rang.


    at this time, outside Chen Xin''s shelter, a police armored vehicle was parked at his door.


    "Chen Xin said that he would open the door immediately." On the bus, a special police member put down his walkie talkie and reported to Li Tou and a man sitting next to him who was not in police uniform and looked like an official.


    Both nodded and said nothing more about it.


    In the previous operation, although not only Qin Lan was injured and hospitalized, but also several other members of Li Tou''s team were also injured and treated in the hospital, even though they were short of manpower, they were still sent out to work with the staff of the joint investigation team on the non official shelters under the current situation of mobilizing the whole city for large-scale rehearsal Work.


    "Here lives a member of the public who has cooperated with our special police team. He mainly provides fresh vegetables for our special police team in exchange for some survival materials. We have checked before, and there is no suspicion." Li Tou explains the situation to the officials around him, but he is obviously helping Chen Xin to say a good word to avoid the possibility of Chen Xin being suspected.


    "Of course, the work of the comrades of the Municipal Bureau is trustworthy, but the joint investigation team has decided to conduct a second inspection, which is safer." The official like man nodded slightly, and did not make any obvious response to Li Tou''s words.


    However, looking at his manner, Li Tou also understood what he said, and he listened to it.

 Chapter 178

    "Lao Li? Why are you here again? Haven''t you checked it before? " Opened the door of the shelter, let the special police team and the staff of the investigation team into the shelter, Chen Xin asked Li Tou his doubts.


    "I came here once last time, but this time it''s the joint investigation team''s request. Comrade Chen, please understand and cooperate with our work." Li Tou is still polite to Chen Xin. After all, he knows that Chen Xin has a good relationship with Qin LAN and Ding Ning, and he doesn''t seem too serious.


    Chen Xin also nodded his head and affirmed: "I''ll try my best to cooperate if I can, but what do you want to do this time? You know all about it before. "


    "In fact, it''s still the same question. Comrade, you just need to give a simple answer." The staff from the joint investigation team spoke to one side.


    Chen Xin heard what he said and looked at Li Tou. Seeing that Li Tou didn''t show much, he nodded: "OK, let''s talk inside. It''s cold outside."


    After that, he took Li Tou, the staff of the joint investigation team, and two other special police officers to his refuge. In order to avoid suspicion, Chen Xin did not close the outermost door.


    After passing through the decontamination room at the gate, the staff of the joint investigation team obviously saw the crossbow at the top of the corridor. They were surprised and said, "comrade, you What''s it for? "


    After upgrading the system, the original crossbow has already become a four armed Heavy Crossbow, and it is equipped with a unique gear structure and loading mechanism, which makes it a continuous fire weapon. From the appearance, it can be said that it is particularly ferocious.


    In particular, Chen Xin installed the Heavy Crossbow at the top of the passage and pointed it directly at the entrance of the passage. Anyone who entered the passage would feel that the crossbow pointed at his head.


    "This..." Chen Xin heard that the staff member asked about his bed crossbow. Seeing that Li Tou didn''t say anything, he explained to him, "it''s a little defensive measure. After all, I live alone. If someone breaks in, it''s also a defensive measure, which can at least block dangerous elements."


    Hearing what Chen Xin said, the staff member could quite understand his idea. He just looked up at the crossbow with thick fingers and said, "safety measures really need to be taken, but the bed crossbow is a bit Are you exaggerating? "


    Chen Xin didn''t know what to say about this evaluation. He just laughed and led them to the shelter.


    After they sat down in the living room, Chen Xin said to them, "I don''t know what you are going to ask this time. If you have anything I need to answer, just ask."


    "Don''t be nervous, comrade. We just want to know the basic information. You just need to tell me some basic information about you, such as how many people live here and the basic personal information of each person." The staff of the joint investigation group took out a questionnaire and asked Chen Xin while filling in the information.


    Because there is not much to ask, Chen Xin is really the only one living here, and soon the staff of the joint investigation team completed the investigation.


    Looking at the staff to collect the questionnaire, Li Tou said to Chen Xin, "Comrade Chen, please show us around. It''s routine. Please forgive me."


    "No problem. Anyway, you''ve seen it last time." Chen Xin didn''t object to this. Li Tou just wanted to look around, not to mention searching. Chen Xin would not ask him for a search warrant.


    So they looked around in Chen Xin''s shelter.


    Chen Xin is not a big place here, so he soon looked around.


    Because they have been here once, Li Tou and others are not surprised by Chen Xin''s situation here, but for the staff of the joint investigation team, they are shocked by the abundant material reserves in Chen Xin''s storeroom and the sprouting works in the planting greenhouse.


    "It''s really It''s amazing The staff member''s eyes widened. Since the end of time, it''s hard to see so many emerald green colors even in the official shelters.


    "It''s all right. It''s mainly the preparation before the disaster." Chen Xin was modest for a moment, and said to Li Tou by the way: "I recently got a batch of seeds, including cucumber, tomato and other vegetables, which have been planted this time. If there is no accident, we should be able to provide more kinds of vegetables in the future. At that time, I hope your special police team can exchange more materials for me."


    When Li Tou heard what Chen Xin said, he quickly agreed happily.


    To be able to eat more vegetables is of course a dream. Li Tou can''t and won''t refuse such a thing.


    After watching Chen Xin''s greenhouse, his whole shelter was checked again. No suspicious places were found. Li Tou and others were ready to leave.


    But just as they were about to leave, Li Tou noticed Chen Xin''s water purifier and scattered drawings on the workbench, so he asked curiously, "Comrade Chen, what are you doing? Looks like a car? ""I''m going to rebuild my car. In this weather, ordinary cars can''t drive out. It''s too bad not to drive, so I have to rebuild my car." Chen Xin didn''t hide his intention. He explained to Li Tou and said by the way, "but now there are still some materials missing. Maybe we need to find someone to exchange them."


    Li Tou was a little strange at first when he heard Chen Xin say that, but he noticed the staff of the joint investigation team standing beside him. He immediately understood Chen Xin''s concerns, so he didn''t say anything, so he nodded to Chen Xin and left with them.


    Seeing them off and closing the door of the shelter again, Chen Xin was a little relieved.


    Although he didn''t do anything bad and was not afraid of ghosts knocking on the door, Chen Xin was still a little nervous when he was visited by special police twice in a row.


    If only the special police team is OK, everyone has interests, and people know him well. But with the staff of the joint investigation team on the side, Chen Xin is really afraid that the other party will find out that he has a gun.


    Now this kind of investigation of dangerous elements is found to have a gun, even if the gun is from the special police team, Chen Xin will inevitably cause trouble, even involving Qin LAN, uncle Ding and the special police team.


    You know, even if Chen Xin shot and killed three people last time, Qin LAN took the matter and said it was her shot. Chen Xin just saw people killed and covered up the fact that he had a gun.

 Chapter 179

    After using his own materials to make the parts that can be made at present, and even adding half of the track, Chen Xin''s materials are exhausted.


    Although there are still many parts in the storage room, those parts can not be applied to vehicle transformation unless Chen Xin recycles them into raw materials and then reprocesses them.


    In order to avoid this unnecessary waste, Chen Xin decided to find someone to get some more resources.


    It is estimated that the SWAT team will not be able to do so for the time being. After all, the SWAT team has to avoid suspicion on the top of the storm, so what Chen Xin can find is the group Friends of the survival group and Li Yulong.


    The group Friends of the survival group don''t have much resources to exchange, and they mainly rely on survival materials. They also need to collect the parts needed to transform the car to get them.


    Therefore, after Chen Xin said this in his daily routine exchange of news, he did not place his hope on how much materials the group friends could get him. Instead, he set out to enter the city again to find Li Yulong.


    Li Yulong has now moved to the small shelter that will be used as the plantation and trading market he wants to operate next. However, because the municipal government has temporarily stopped the project, although the small shelter has been reopened and the relevant construction and transformation is still in progress, it can not be put into use.


    When Chen Xin saw Li Yulong, he was standing in the area originally designated as a plantation and was angry with his subordinates.


    "What''s the matter, Bruce, with such a big fire?" Being taken to Li Yulong''s side and looking at his angry appearance, Chen Xin asks curiously.


    "I''m so angry! Brother Chen, you''re just in time! " When Li Yulong saw Chen Xin''s arrival, he immediately adjusted his expression, but his anger still remained: "you know the situation, you can judge. Now the municipal government has stopped the project, should the planting greenhouse be temporarily sealed? Even if it''s not sealed, it''s better to grow something for storage, isn''t it


    "That''s right. What''s the matter?" When Chen Xin heard Li Yulong''s question, he turned his eyes to the plantation in front of him.


    Planting has already started in the plantation, but as Li Yulong said, when the municipal government temporarily stops the project, it should not continue to plant crops in the plantation.


    Because at the beginning of the planning, the plantation was used to grow crops with high economic value, such as fresh vegetables and fruits, but all of these things have a very distinctive feature, that is, they are not easy to preserve.


    It is not impossible to freeze it at low temperature, but when it is thawed again, it is basically frozen, and can only be refrigerated at low temperature, and there is still a time limit for preservation.


    If it is made into freeze-dried or dehydrated vegetables, although the nutritional value will not have any problem, there will undoubtedly be a huge gap between fresh vegetables and fruits in taste, and there will also be a big gap in price.


    Although Chen Xin doesn''t know what kind of crop Li Yulong''s men are planting, from the leaf, it is likely to be some kind of fruit.


    "These guys don''t know if they mean to annoy me, or they don''t understand me at all. They grow strawberries and grapes!" As soon as Li Yulong mentioned it, he was very angry, obviously very dissatisfied with it.


    Looking at his angry appearance, Chen Xin couldn''t help laughing.


    Of course, it''s not a mistake for Li Yulong''s men to grow strawberries and grapes. However, in the current situation, it''s really inappropriate for them to do so.


    If everything goes according to the original plan, planting strawberries and grapes is certainly a good choice. With the opening of the trading market, fresh strawberries and grapes will be directly put on the market for trading, which will undoubtedly become the most marketable commodities.


    Even if it can''t make a huge profit, it can also make Li Yulong''s pot full.


    But now the project has been stopped, and I don''t know when it can be reopened. Under such circumstances, when the trading market can be set up, there is a question mark. Whether these fruits that can''t bear to be stored can be sold in time after they are planted is even more a big question mark.


    If it can''t be sold in time, all the investment in planting this batch of fruits will be wasted.


    Even before the disaster, it can make the growers lose all their money, not to mention the end of the world where every resource can not be wasted.


    "Don''t worry about getting angry. Think about how to remedy it." Chen Xin can only persuade Li Yulong not to get angry.


    "Remedy? How can this be remedied? The seeds have sprouted. Can''t they all be pulled? " Li Yulong was still upset. Although his family had a lot of crop seeds in reserve before the disaster, he could not afford such a waste.


    Chen Xin really had some ideas about how to remedy the problem. He also had a share of this kind of plantation, so he said, "it takes time for strawberries and grapes to ripen. There''s no need to worry about this for the moment. Maybe the municipal government can find out what happened during this period? At that time, you will naturally lift the ban, and these things will naturally be sold when they are planted. "


    "Brother Chen, what you said is the most ideal situation. The problem is that the city government is making such a big move now. How can it have a result in a short time?" Of course, Li Yulong knows that this kind of situation mentioned by Chen Xin is possible, but this kind of thing is too idealistic. For Li Yulong, he will not place his hope on this kind of idealistic situation."Of course I know this is the most ideal situation, but you can''t say it''s impossible, can you?" Chen Xin laughed and saw that he was not so angry, so he patted Li Yulong on the shoulder and continued to say, "if it''s too bad, you can make strawberry jam and wine. It''s not complicated to make, and it''s more storable. You don''t have to worry about getting angry. Maybe jam and wine sell better?"


    After hearing Chen Xin say so, Li Yulong''s mood calms down, and after swearing at his subordinates, Li Yulong and Chen Xin go to the rest room.


    Sitting down in the lounge, Li Yulong poured water for Chen Xin and asked, "brother Chen, how did you come here today?"


    "I''m going to rebuild my car recently, so I''d like to ask if you have any spare parts. If you have, I''ll replace them." Instead of being polite to Li Yulong, Chen Xin told him his intention.


    Hearing Chen Xin''s intention, Li Yulong frowned and hesitated. Then he said, "brother Chen, how are you going to transform? I remember your car was an SUV, right? What parts do you need? Do you have a list? I don''t have all the spare parts that I store now. I can''t guarantee it for you. I can only say that I''ll try my best to collect them for you. "


    "It''s enough to have you. What I need is basically some common parts." Chen Xinchong and Li Yulong laughed.

 Chapter 180

    Chen Xin and Li Yulong have reached an agreement on auto parts. After giving him his list, he is ready to leave.


    He is going to visit Qin LAN in the hospital today, so he didn''t sit here for a long time.


    Just when Chen Xin left, he unexpectedly saw the people who should not be here.


    "Doctor"? What are you doing here? " Looking at the "doctor" appearing in front of him, Chen Xin was surprised why he was here. Especially, he didn''t look like he came in from the outside. He didn''t have protective clothing on him. He looked like he was living here.


    "The writer? The warmth of our shelter is too poor. Xie Chang and I originally planned to go to the official shelter. But Mr. Li said he was short of people here, so Xie Chang and I moved here. " "Doctor" was surprised to see Chen Xin, but he politely said hello, but his face was a little haggard. It seemed that the death of his parents had a great impact on him.


    Listening to the opening of the "doctor", Chen Xin''s eyes slightly coagulated. The doctor''s name used to be Xie Chang, but they were all Xiao Xie. When did they become unfamiliar?


    However, Chen Xin did not go into the matter. He nodded to the doctor and left.


    While driving to the hospital, Chen Xin is happy to see the doctor move to Li Yulong.


    After all, "doctor" is a qualified doctor. He used to run a small clinic. He moved to the future trading market, which is good for attracting customers in the future.


    Of course, hospitals can provide perfect medical services, but sometimes people prefer small clinics.


    Chen Xin arrives at the hospital soon. When he comes to the ward, Hongrui is checking Qin LAN.


    "Hello, Dr. red, how did you come to examine Alain?" Chen Xin looks at Hong Rui and greets her.


    "As police officer Qin''s psychologist, this is just a routine examination." Red Rui is still familiar with the dress of short skirt, silk stockings and white coat, which is in sharp contrast with Qin Lan''s simple hospital uniform: "Mr. Chen, you''ve been running to the hospital very often recently! Is there any attempt against officer Qin? "


    Hongrui teases Chen Xin and says "you chat" to Qin LAN. Then she turns around and leaves the ward.


    looked at red Rui leaving. Chen Xin rubbed his nose and said, "she didn''t spray perfume today."


    "Sit down, ah Xin. I''ll ask you to deliver food to me every day. It''s really troublesome for you! Thank you Seeing Chen''s new hand holding a heat preservation bucket, Qin LAN knows that he has sent food to her again, which makes her moved and feel that it''s too troublesome for Chen Xin.


    "It''s just a meal for you. What''s the trouble? Didn''t you take care of me when I was in hospital?" Chen Xinchong and Qin LAN smile and put the heat preservation bucket on the bedside table. After opening it, she takes out all the food in it: "by the way, where''s xiaodingren?"


    "I asked her to go back and help me with some washing and changing clothes. After staying in the hospital for a few days, her clothes should also be changed." While answering Chen Xin''s question, Qin LAN looked at the food Chen Xin took out of the thermos: "ah Xin, would it be too extravagant for you to cook so much food for me every day? I feel like I''ve gained weight these days! "


    Hearing what Qin Lan said, Chen Xin couldn''t help laughing: "how can it be? You are the wounded now. You can get better by eating more. "


    With that, Chen Xin has brought the food to Qin LAN and started to feed her.


    Although Qin LAN only hurt one hand, she can eat by herself, but in order to take care of her and avoid the wound, Chen Xin still insists on feeding her.


    While feeding Qin LAN, Chen Xin also talked to her about Li Tou''s investigation at his home.


    However, it made Qin LAN feel very strange: "you said Li Tou and they went to your house twice? It''s a bit strange. It''s enough to do one row. It''s really strange to do two rows in a short time! "


    "Strange? Why do you say that, Alan? " Chen Xin heard Qin LAN say so, immediately curious.


    "Generally speaking, large-scale mopping usually only needs to be done once, because the workload of mopping is very heavy, and now the flow of people between various shelters is very small. It''s enough to do a mopping once to find out the situation within a certain range. There''s no need to do such intensive and frequent mopping twice in a short time." The more Qin Lan thought about it, the more confused she felt. She wanted to be able to leave the hospital immediately and find out what was going on.


    But now she is injured, and is on holiday by Uncle Ding. Even if she has doubts, she can''t participate in the investigation. She can only think about it in vain.


    Listening to Qin Lan''s puzzled words, Chen Xin didn''t feel wrong as she did, but said: "Lao Li said that the previous mopping was arranged by the municipal government, while the latter mopping was arranged by the joint investigation team, and the two mopping were ordered by different people, so it should be possible, right?"


    "It''s against common sense to arrange two rounds of rehearsal in a short time, unless it''s..." Qin Lan said here, suddenly want to think of something, eyes suddenly turned to Chen Xin, the whole person is excited to sit up, almost his hand spoon all knocked down.


    Looking at Qin Lan''s excited appearance, Chen Xin quickly put down the spoon in his hand and pressed her back to the bed: "lie down, lie down! It''s not good yet! Why are you so excited? ""Ah Xin, you don''t understand! If it happens twice in a short period of time, it is very likely that the area where the suspect is located has been determined for the first time, and the second time is to find out the suspect after narrowing the area! " Qin LAN excitedly looked at Chen Xin and said quickly: "that is to say, if there is no other reason, it is very likely that the first time to find clues when touching the row, to determine the area where the suspect is located, and your home is in this area, so there will be two consecutive touching the row door!"


    Hearing what Qin Lan said, Chen Xin raised his eyebrows, but he still shook his head and said, "it doesn''t matter if you find the suspect. Your task now is to take good care of your injury. Even if there''s anything, you''ll have to wait until your injury is healed. Can you still shoot like you are? "


    Chen Xin''s words make Qin LAN unable to refute. Now she is in such a state of hanging an arm that she is reluctant to use a pistol, let alone a sniper gun. Moreover, even if the wound is healed and the thread is removed, it still takes time for her to recover to the normal level.


    But Qin LAN did not give up and said: "but in this way, ah Xin, you will be in danger there! What if the terrorists are after you? That''s a great hiding place for you

 Chapter 181

    "Hiding in my house? How ungrateful are they? " Qin Lan''s words made Chen Xin dumbfounded: "don''t mention that the people of your special police team come to exchange materials every other month. I have regular contact with longniang and Xiaolong every day. If I haven''t heard from them for one or two days, maybe there won''t be anything. If I haven''t heard from them for three or five days in a row, others may not have any reaction, but longniang will surely find that she doesn''t know Yes, to call the police. "


    "But the problem is that even if Qing Yan or other people find out something is wrong, you''ll have an accident at that time! Those are terrorists. Now it''s the end of the world. If people want to rob you, how can they be polite to you? " Qin LAN of course knows that Chen Xin is telling the truth, but she is still deeply worried about Chen Xin.


    Because all these can only be regarded as remedial measures after the accident. If Chen Xinzhen has an accident, it is very likely that he will be killed by the terrorists or other criminals who seize his refuge at the first time, leaving no possibility for others to rescue him.


    Although it may not be appropriate to say that, in this case, the survival rate of men is far lower than that of women.


    In most cases, men will be killed for the first time because they are more threatening, but women are not. Because in many people''s subconscious, women are much weaker. Therefore, it is a subconscious choice for many people to leave less threatening women to enslave or vent their desires instead of killing them for the first time.


    As for leaving men to be enslaved, it may still be possible for ordinary criminals, but Qin LAN doesn''t think they will be so merciful to terrorists who are not afraid of death as before.


    And another possibility Qin LAN looked at Chen Xin''s face, and immediately drove the idea that it would affect appetite out of her mind.


    Chen Xin doesn''t know what Qin Lan thought just now, but after thinking about what she said, Chen Xin said, "my refuge is safe. Without heavy weapons or explosives, it''s basically impossible to enter my refuge.


    And I''m not without resistance. If I can''t resist for a while, I still have the strength to send out distress signals and wait for people to come to the rescue. "


    Hearing what Chen Xin said, Qin LAN admitted that he was right, but still worried about Chen Xin and said, "ah Xin, your shelter really has no big problem in defense, but now you have to go out every day. What if someone stares at you and attacks you when you go out? Otherwise, you''d better not come to deliver food to me. During this time, you''ll stay in the shelter and don''t go anywhere! "


    In Qin Lan''s opinion, Chen Xin''s resistance to real criminals or even more dangerous terrorists can be ignored, although he is not so helpless.


    But Chen Xin didn''t think so. The reason is that the upgraded intelligent pistol and supporting tactical eyepiece are used by Chen novice.


    In the dark environment where everyone has poor vision, Chen Xin has a tactical eyepiece with infrared vision, which is similar to unilateral battlefield transparency.


    Coupled with the intelligent pistol that can automatically aim at the lock, it can be said that the enemy can blow his head as long as he is seen by Chen Xin.


    Under such circumstances, Chen Xin doesn''t feel that he can be in any danger when he meets a small number of criminals or enemies. After all, Yanguo''s gun control is still very strict. Even now it''s the end of the world, it''s not easy to get a gun.


    So Chen Xin is not particularly worried about his own safety.


    However, for Qin Lan''s worry, Chen Xin also understood and responded: "what you said is reasonable. When you leave hospital, I won''t come to deliver food."


    After hearing Chen Xin say so, Qin LAN plans to persuade him again, but after hesitating for a while, she still doesn''t say any more. After all, her wound recovers quickly, and she can be discharged in a few days. Moreover, Chen Xin is not a person to be advised. It''s good that he is willing to take a step back.


    Nevertheless, Qin LAN told Chen Xin: "ah Xin, you must be careful when you go out these days. Before that group of terrorists were very dangerous. You must take the gun with you. If there is any danger, don''t shoot so many directly!"


    She should not have said that to Chen Xin as a policeman, but because of her worry about Chen Xin''s safety and what happened last time, Qin Lan thought that Chen Xin might be worried about shooting, so she specially told him.


    Compared with others, Qin LAN hopes Chen Xin is safe and sound.


    Chen Xin naturally agreed. After all, compared with other things, his own life is more important.


    Especially now, in the end of the world, we can only talk about other things when we are alive, and there will be nothing when we are dead.


    Hello, Qin LAN finished her meal and chatted with her for a while. Until Ding Ning came to the hospital with Qin Lan''s washing clothes, Chen Xin was ready to go back.


    Seeing that Chen Xin is ready to leave, Ding Ning follows Chen Xin out of the ward in the name of sending him out. He grabs Chen Xin in the corridor and asks him, "ah Xin, can you live for two more people?"


    "What about me? You can squeeze it. What''s the matter? " When Chen Xin heard Ding Ning''s question, he nodded after thinking about it."When sister LAN leaves the hospital, I''ll take her to you for a while." Ding Ning looked a little serious and said it seriously.


    When Chen Xin heard what Ding Ning said, he suddenly felt a little strange. Thinking of the recent events, he couldn''t help but feel awed in his heart and asked Ding Ning, "do you two move there? What''s the matter? "


    Ding Ning heard Chen Xin ask, gave Chen Xin a "you guessed right" look, but did not explain, instead deliberately raised the volume, said: "what can happen! Don''t you welcome me and sister LAN to live with you? Go back and tidy up the place! Don''t let me go with sister LAN and see that you are in a mess everywhere


    With that, Ding Ning pushes Chen Xin out, but in the process of pushing Chen Xin, she seems to have put something in Chen Xin''s pocket.


    Chen Xin naturally understood Ding Ning''s suggestion, but quietly pretended to be unknown, so he was pushed out of the hospital by Ding Ning.


    After leaving the hospital and getting on the bus, Chen Xin drove back and was about to get out of the city. Then he took out what Ding Ning had just put in his pocket and took it out. It was a small note.


    I saw the words "cooperate with the action, protect Qin and Ding, burn after reading" written in very small words.


    Looking at these words, Chen Xin immediately realized that he took out the cigarette lighter on the car and lit the note. After burning the note so that he could not see what it was written, he threw the fragment out of the window and was blown away.

 Chapter 182

    The content of the note makes Chen Xinli nervous and alert. He understands that this is obviously a big move of the police, and he is involuntarily involved in this matter.


    Why Qin LAN and Ding Ning were given a month''s leave before, and why their shelters were checked twice has also been explained.


    Chen Xin doesn''t reject cooperation with the police. It''s also a good thing that Qin LAN and Ding Ning can protect him.


    However, the two girls moved to live with him, even in order to protect him, it still formed a certain trouble for Chen Xin.


    After all, it''s two girls. They live here. It''s a question where they sleep.


    If only Qin LAN, it''s easy to say, anyway, the two people have not lived together, which can''t be regarded as a problem.


    But Ding Ning and Chen Xin are just ordinary friends, and they don''t even have a very good relationship, which obviously causes Chen Xin''s distress and makes him think about giving them two places to live.


    At least, arrange a separate room for dinning.


    While thinking about this problem, Chen Xin went back to his refuge.


    Since he knew that he might be in danger from Ding Ning, he was naturally concerned about the safety of the refuge.


    After closing the gate, Chen Xin is also planning to improve some of the protection, such as upgrading the gate, improving the protection performance and adding a little defense weapons.


    However, this can be postponed temporarily. Chen Xin still has to take the lead in solving the housing problems after Ding Ning and Qin LAN come.


    In fact, this problem is not too difficult to solve. After all, in addition to the bedroom and living room, there is also a medical room. If you don''t mind, you can sleep in the multifunctional operating chair. After all, the chair is a temporary operating table, which is the size of a train sleeper.


    It''s just that it''s too simple. If Chen Xin has no other way, he can consider doing it. But when there are other ways to think about it, he still doesn''t intend to do it.


    Sitting in front of the workbench, opening the system interface and browsing the various materials in the warehouse, Chen Xin is thinking about making a high and low bed by himself.


    In fact, it''s not complicated to make a high-low bed, and the materials used are also simple. If it''s the kind of iron frame bed in Chen Xin''s university dormitory, it even requires only a few steel pipes to weld one.


    Chen Xin looked at the materials in his warehouse. There are still a number of steel pipes, including angle steel, channel steel and I-beam. He wants to weld a high and low bed. Even if there is no system, Chen Xin can use these materials as long as he knows how to weld.


    So Chen Xin did not hesitate. He pulled out two steel pipes from the storage room and cut them into four columns. Then he cut them with four angle steels and welded them into two rectangular frames. He connected the four columns to the top corners of the two rectangular frames. A high-low bed frame was finished.


    A few beams are welded in the rectangular frame, and then the bed board is laid. This bed can sleep. The high and low bed in Chen Xin''s college dormitory is such a thing. The quality may not be as solid as Chen Xin''s own. After all, he has the impression that one of his overweight classmates collapsed the bed.


    However, although the high and low bed was made, Chen Xin did not dare to use it to sleep for Qin LAN and Ding Ning. After all, it was too simple to have a bed board.


    So after making the steel frame, Chen Xin found a composite board and a sheet iron from the warehouse as additional materials, and spent 20 survival points to upgrade the bed.


    After upgrading, the high and low bed looks like a little bit. The four pillars have been thickened a lot, and the bed board has been added to the bed. Besides, there is a ladder for climbing up and down. It looks like that.


    With a bed, the rest is easy.


    After leaving the workbench and looking at his bedroom, Chen Xin opens the system interface again.


    "Containerized composite house bedroom components"


    "upgrade scheme 1: upgrade the box material, improve the thermal insulation performance, upgrade the temperature regulation and air circulation performance, life support level + 1, upgrade the required survival 3000"


    "upgrade scheme 2: upgrade the internal soft decoration material, increase the smart home function, living comfort level + 1, the overall science and technology level + 1, upgrade the living environment" This is the data displayed by the system when Chen Xin checked the bedroom upgrade options before, but after Chen Xin found out how to use the system, now he can control the upgrade direction of the upgrade scheme.


    So when he opens the bedroom upgrade interface again, the data displayed becomes:


    "containerized combined house bedroom component"


    "upgrade scheme 1: expand the living area, accommodate + 3 people, upgrade the box material, improve the thermal insulation performance, upgrade the temperature regulation and air circulation performance, life support level + 1, upgrade the required survival point 50 "Upgrade plan 2: living space + 1 (single living space can accommodate 2 people), upgrade internal soft decoration materials, increase smart home function, living comfort level + 1, overall technology level + 1, and upgrade the required survival point of 6500"The price has gone up, but the upgrade plan has obviously added something.


    Seeing that the system upgrade plan has changed under his own will, Chen Xin immediately nods with satisfaction. As for the cost of the upgrade, the materials required for the two upgrade plans are in his storeroom, and the materials Chen Xin prepared for the overall upgrade refuge have a considerable degree of coverage, so Chen Xin can get the upgrade materials required for both plans.


    Only in this way, about one fifth of his materials will be used up, which will undoubtedly have a great impact on his overall upgrade of the refuge.


    However, at present, the materials for the overall upgrade haven''t been put together. It seems that it''s not impossible to misappropriate part of the materials to upgrade the urgently needed bedrooms. After all, we were going to get another batch of materials, but now misappropriation is nothing more than getting more materials.


    After thinking about it, Chen Xin only chose the upgrade of scheme 2.


    After putting in the materials, using the survival point, confirming the upgrade, the green light is still flashing. Everything is as simple as changing the theme style of the computer display interface. Just a refresh, it becomes different.


    The high and low bed that Chen Xin made just now has disappeared from the side of the workbench, and a new door has appeared next to the original bedroom door of the living room.


    When you open the door, you can see a bedroom with a sense of technology and a bit of future color. The simple style, white main tone and warm light source make the bedroom look not like a refuge in the end at all, but like a future residence in a science fiction movie.

 Chapter 183

    This bedroom belongs to the room expanded after upgrading, which is the same size as Chen Xin''s original bedroom in area. A white high-low bed is against the wall, and the bed is covered with clean white sheets and a brown blanket. It looks very neat, and people can''t bear to disturb it.


    This is an upgraded version of the high and low bed made by Chen Xin before. The material is obviously no longer steel tube, but a little metal texture material to the touch, and the shape is more like what will appear in science fiction works.


    In addition to the bed, there is a desk and a small round table in the room. The desk and the bed are at one end of the room, leaning against two corners respectively. The small round table is placed at the other end of the room, and there is an oxygen box beside which green plants can be planted.


    This is a spare oxygen generator in Chen Xin''s warehouse. It can be used as an equipment after upgrading materials. Green plants can be planted in the box to provide more oxygen for the bedroom.


    But now the oxygen box is still empty, obviously the seeds need to be added.


    Looking at the empty planting box, Chen Xin plans to transplant some of the herbs that Hongrui promised to plant. While increasing oxygen, he can also use the natural aroma of herbs to increase the effect of meditation.


    In addition to these, there is a white radiator under the wall with the desk, which is connected with the ground source heat pump to provide enough warmth for the bedroom. Even after the upgrade, the thermal insulation performance of the bedroom is enough to ensure that it is very comfortable inside.


    The light in the room comes from the two light strips on the ceiling. The non dazzling warm color light adds a warm feeling to the room and makes the bedroom more comfortable.


    As for the two wardrobes placed at the foot of the bed and another corner, they are just ordinary ones.


    Chen Xin cares about the material of the wall. When he reaches for it, it feels like plastic steel. The frosted surface doesn''t reflect strongly, and it feels very comfortable.


    After checking the room and experimenting with the smart home and temperature control functions mentioned in the system upgrade plan, Chen Xin can see where the technology level + 1 and life support level + 1 are reflected.


    Near the door of the room, there is a touch screen like device on the wall. After opening, it can set the room. Then it can intelligently adjust the light, temperature and ventilation of the room according to the settings, monitor the air humidity, body comfort and other data of the indoor environment, and even play music.


    There are several chairs in the room, one is the back chair in front of the desk, and the other three are the low sofa in front of the small round table. Chen Xin tried it and found it very comfortable.


    Experiencing the comfort of the upgraded room, Chen Xin is extremely satisfied with it. He deeply feels that the survival and resources he has spent are not in vain, which has greatly improved his quality of life.


    However, after checking the bedroom to be a guest room, Chen Xin has to check his own bedroom.


    After all, Chen Xin put a lot of things in his bedroom. The entry of technology level + 1 made him salivate. He was eager to see if the things in his bedroom could also be covered by this attribute.


    However, when he returned to his room, he was disappointed that the weapon cabinet and laptop, the two items he was most looking forward to, had not been upgraded.


    The whole room is like a replica of the room next door, but there is an extra weapon cabinet and workbench beside the desk.


    All of Chen Xin''s personal belongings are still placed as they are. Even the wine under the bed is put into the upgraded drawer under the bed.


    Looking at all this, although Chen Xin is disappointed, he has no dissatisfaction. After all, this is only the upgrade he expects, but strictly speaking, these things can''t be included in the category of bedroom.


    Instead of worrying about it, Chen Xin sat down in front of the weapon workbench and decided to make several defensive weapons, which he added when upgrading the gate to increase its defensive power.


    Bows and crossbows are excluded from Chen Xin''s choice of defensive weapons.


    It''s not that the crossbow is not easy to use. The Heavy Crossbow he installed in the corridor has quite terrible power. If someone is shot at the door, the power will not be less than that of being shot at close range by a large caliber anti equipment sniper rifle.


    The key problem is that the bow arm and bowstring of the crossbow have high requirements on the material, and the service life of the crossbow will be seriously affected in the low temperature and severe cold environment.


    Although the property of the weapon cabinet includes the maintenance of weapons, Chen Xin has not used this function so far, and he is not sure whether the function of the weapon cabinet for crossbow damage in severe cold environment can be repaired.


    So what Chen Xin plans to do is still guns.


    Although there is only one drawing of pistol on the worktable, the principle of firearms is interlinked in terms of structure. It is not impossible to transform the pistol to produce more powerful firearms.


    And no matter how poor it is, it''s not impossible to make a pistol and upgrade it to a mini submachine gun.


    What''s more, Chen Xin has all kinds of information in his computer, including gun drawings. From the most old flint guns to the Mauser rifles and leenfeld rifles in World War I and World War II, although these weapons were invented decades or even hundreds of years ago, no one says that the old weapons can''t kill people. Swords and swords have been used by human beings for thousands of years, and they are not the same today Still a killer?At the beginning, Chen Xin collected these drawings only to accumulate writing materials, but also a personal hobby. However, it has to be said that these drawings are a valuable asset and a great help for him now.


    Chen Xin doesn''t plan to make a rifle. As for the systematic drawings of pistols, he doesn''t bother to look through them. What he wants to do is machine guns.


    After all, although the old-fashioned Markham machine gun was the first successful automatic gunpowder weapon in the world, it killed 60000 people in one day in the Somme River battle of the first World War. Until the 1970s, the country still used this kind of old-fashioned gun, even though it was only equipped with militia troops.


    If a Markham machine gun covering the whole gate is mounted in the observation room above the gate of the refuge, Chen Xin feels that even if there is an army attacking his refuge, it will not be able to enter without heavy weapons.


    As for the drawings of Markham machine guns, the drawings of weapons that have been used for more than 100 years are really easy to find. There are a lot of drawings of derivative models. When there is a network, you can easily find them by searching the Internet. There are several different models of drawings in Chen Xin''s computer.


    Now all he needs is to make it.

 Chapter 184

    It is not difficult to make a machin machine gun. This kind of antique model is even sold on a treasure. Its unique elbow joint reentry mechanism is not complicated in structure.


    compared with the drawings, Chen Xin used the system to transfer materials from the storage room.


    Although high performance steel is needed to manufacture machine guns, ordinary steel is enough for the system, and Chen Xin can confidently hand over the rest to the system.


    With the help of the processing function of the worktable, makchin''s parts are manufactured, and then these parts are assembled bit by bit, and soon makchin appears on Chen Xin''s worktable.


    Although Chen Xin has not yet completed all the assembly, he has only completed the barrel and machine parts, not even the most important bracket. The unpainted gun body is completely in the original metal color and looks miserable, but he does not hide the power of this terrible killing machine.


    Markham heavy machine gun is the first truly successful automatic weapon in the world, which uses gunpowder and gas as energy. Once applied, it has become the most efficient killing machine in human history.


    In the war between the Japanese and the lucians, the army God Mumu Xidian, who was blown to heaven by the Japanese, led 60000 people to attack the positions of the lucians, and adopted a very brainless strategy of pig sudden advance, killing 5000 people in three hours.


    Although he defeated the lucians in the end, by the time of the final attack, namutidian had 60000 soldiers, and more than 30000 people had been killed.


    In the first World War, makchin won the title of widow maker for his terrible killing efficiency.


    In the battle of Somme River, the death firepower network composed of hundreds of makchin killed more than 60000 people in one day, and almost killed a whole generation of people in Europe at that time in the first World War.


    This horrible killing machine uses the recoil force generated by bullet shooting to achieve automatic shooting. Compared with the great Bodhisattva Gatlin of South Africa, which was invented by federal doctors to reduce the casualties of soldiers, it is much more efficient and easier to use and maintain. Therefore, it soon replaced Gatlin after it came out.


    However, because of its high firing rate of 600 rounds per minute, Markham will produce a lot of heat when shooting. In a few minutes, the barrel of the gun will turn red because of shooting.


    Therefore, there will be a huge round sleeve on the barrel of Markham''s gun. When it is used, cooling water will be injected into the sleeve to cool the barrel. As long as there is water in the sleeve, the temperature of the barrel will not exceed 100 degrees, and it can continue to shoot.


    Some people may think that this kind of weapon has great advantages in cold weather. After all, if the environment is cold enough, the cooling effect must be very good.


    But in fact, there are a lot of inconveniences when makchin is used in cold areas.


    Because markqin uses water injection pipe to add cooling water. In cold areas, water drops into ice. Cooling water must burn ice and snow into water before it can be added to the gun barrel, which often causes the cooling water to freeze and affects the use.


    Therefore, in cold areas, antifreeze must be added to the cooling water, and the widely used antifreeze at that time was alcohol.


    This is the reason why some lucians drink antifreeze, because the cooling water added with alcohol as antifreeze is really a delicious drink for Lucian soldiers, who were called gray cattle at that time. If they have nothing to drink, who can control the gun?


    Later, in order to solve this problem, the sovya people learned from the Finns and improved the nozzle on the barrel sleeve, turning it into a big flap, which can be directly filled with ice and snow, which effectively solved this problem.


    Of course, for Chen Xin, he won''t use such a troublesome way to cool the barrel of the gun. After all, he has only one person, even if Qin LAN and Ding Ning come, there are only three. It''s better to install defensive weapons at the door, which is fully automatic and can be controlled remotely in the shelter.


    As for the problem of cooling, it may be a difficult problem for people in Markham''s time, but for modern military industry, it can also be solved by replacing it with recyclable coolant for recycling.


    It''s just that the army has already been equipped with air-cooled machine guns, so there''s no need to fight on water-cooled machine guns.


    For Chen Xin, he doesn''t have to worry too much about the coolant. As long as he keeps the firing rate low and doesn''t use it for a long time, makchin manufactured by modern technology doesn''t have much demand for cooling and heat dissipation. After all, the manufacturing process and materials used are completely different.


    The last part was installed on the gun body, and gun oil was added between the parts of the gun body for lubrication. A makchin without support frame was made.


    Looking at this iron guy like a round roller, Chen Xin reached out and patted him, trying to hold him up with both hands.


    Although it''s a bit heavy, it''s still within the range that Chen Xin can hold up. However, it still needs a support frame as a fixed weapon. It''s impossible to hold up and shoot like a light machine gun in movies and TV plays.


    So if Chen Xin wants to use this kind of machine gun, he needs to make a bracket for it.


    However, when Chen Xin was preparing to make a scaffold, he suddenly remembered a picture he had seen. After thinking about it, he decided to make another one.Because only steel is needed to make makchin, soon the second makchin also appeared on the workbench.


    looked as like as two peas in the two identical Mark heavy machine guns on his own workbench. Chen Xin nodded satisfactorily and began to make a support frame.


    Compared with the machine gun itself, the structure of its bracket is more complex, because in addition to being used as a support, the bracket of the machine gun has many different functions.


    Some have added shields to resist the splashing of stray bullets and fragments; some have added seats to shoot on the bracket; some have simply integrated the spare barrel on the bracket, which can be removed and replaced when necessary


    What Chen Xin has done is that he can install two macchin frames together in parallel, and change the original macchin frame into a duplex one.


    Because of the original bracket structure as a reference, it is not difficult to make the double mount bracket. Chen Xin just took a little time to make a bracket that can install the two maxines.


    Although the structure is a little unreasonable and simple, it can hardly adjust the shooting range and angle, but it is still a complete support.


    After installing the two maxims, the name of the system interface changed from Maxim water-cooled machine gun to double Maxim water-cooled machine gun. Chen Xin just ordered the upgrade.


    It''s still the familiar green light, the survival of 100 points and the consumption of part of steel, which makes the original rough and crude double pack Markham become different in an instant after the green light.


    The original white metal appearance has become black, and part of the structure has been replaced by engineering plastics. The diameter of the thick water cooling sleeve has become smaller, but the length has been lengthened. The longer sleeve and the longer barrel not only improve the heat dissipation performance, but also enhance the power of the bullets from the barrel.


    The crude support has also been improved, from the original simple three support feet into a complete support structure. The movable connection structure that Chen Xin did not do has also been added. After removing the fixation, the gun body can rotate within a certain range to achieve multi angle shooting.


    The trigger part has also been modified, from two guns and two triggers to two guns and one trigger, which combines the structure and reduces the complexity of operation.


    As for the upper muzzle, it was also adjusted from the original direction to one side, and according to Chen Xin''s idea, a large capacity magazine was added to the upper muzzle.


    The ammunition chain is still used in this kind of high-capacity magazine, or simply speaking, the magazine is just a ammunition box for loading bullets. However, due to the system upgrade, there is an additional ammunition delivery mechanism on this magazine, which can directly send bullets into the loading port as long as it is installed on the machine gun.


    After finishing the production of the machine gun, Chen Xin believes that no one can break in without heavy vehicles or heavy weapons as long as the double mounted Markham is installed at the gate of the shelter.


    However, a machine gun has a shooting angle limit. After considering it, Chen Xin decided to install two guns.


    So he made the same double machine gun, and was ready to install them on the gate of his refuge.


    The two machine guns were installed on the left and right sides of the gate by Chen Xin, because the terrain outside the gate of the refuge is inverted. Although the snow is accumulated around, the terrain is still flat. To enter Chen Xin''s refuge, you must stand in front of the gate, that is, within the range covered by the two twin mounted markchin firepower.


    In this range, if there is not enough protection, no matter how many people are beaten into a sieve.


    In addition, Chen Xin installed the two machine guns in the wall and only opened a small shooting hole. Even if he wanted to destroy the two machine guns, without heavy firepower, if he wanted to destroy them, even if he wanted to use a human life pile, he could only consume Chen Xin''s bullets in vain.


    The capacity of the high-capacity magazine is 200 rounds, and the two double loads are 800 rounds.


    Even for strafing, 200 bullets from a single machine gun is enough to sweep for almost a minute. If it is a short shot, if you want to consume all these bullets, it may not take hundreds of lives to pile them up.


    In particular, after installing the machine guns, Chen Xin upgraded the door with 1000 survival points and a lot of materials. He strengthened the strength of the door, changed the manual push-pull door to the electro-hydraulic lifting door, and added the automatic aiming function to the two machine guns, and installed the infrared night vision monitor and dynamic induction on the door.


    The infrared night vision monitor and dynamic sensor are directly connected to the computer in Chen Xin''s bedroom. At the same time, they are also connected to two machine guns. Chen Xin can operate them in his bedroom.


    As long as a suspicious person appears and triggers the dynamic response, Chen Xin will be awakened by the alarm bell in his bedroom, and can see the situation outside the door through the computer screen.


    If there''s a conspiracy The four overlapping tongues of fire are a nightmare even on the battlefield.

 Chapter 185

    Two double mounted Markham machine guns have been installed, and the gate looks thicker and stronger after upgrading.


    In particular, the structure of the gate has changed from push-pull type to lift type. The whole gate has been completely embedded in the wall. If you want to open it without lowering the gate, you have to blow up the whole wall.


    After upgrading, the gate, which was originally made of reinforced concrete wrapped with ordinary steel plate, has become a solid heat-treated homogeneous Ni Cr alloy steel plate with a thickness of 30cm.


    During the Second World War, the Japanese used this kind of steel as the main armor of the Yamato class battleship, and stacked its thickness to 650mm.


    At that time, the armor of Daiwa class main gun was 650mm thick, which could not be penetrated by any gun in the immune zone at that time.


    In fact, the Federation found such a steel plate after the war. In order to test the performance of this steel plate, they used the 410 main gun of the Missouri class battleship to carry out zero angle bombardment at a distance of 300 meters before they penetrated such a steel plate.


    However, it is almost a century ago. Now, nickel alloy steel has become a kind of ordinary steel which can be bought in the steel market at a low price.


    Among the materials collected by Chen Xin before, there are such a number of nickel alloy steel columns, which are sold as raw materials for metal processing.


    In Chen Xin''s original plan, these materials were used not only to reinforce the gate, but also to reinforce the internal structure of the refuge.


    Of course, in Chen Xin''s original plan, there was no plan to make the gate into a solid metal door with a thickness of 30cm, and a hollow structure made of a few centimeters of steel plate, which was still reinforced concrete.


    But after Ding Ning gave him the note, the inexplicable sense of crisis made Chen Xin choose to turn the gate into solid metal, although it nearly doubled the survival cost of upgrading.


    Although Chen Xin''s gate is not as thick as the main gun armor of the Yamato class battleship, his enemies also don''t have the main gun of the battleship.


    As for the use of explosives, it can''t affect such thick armor, otherwise there is no need to use armor piercing bullets in war to effectively penetrate the armor of battleships.


    Looking at the gate, which can only be described as solid, Chen Xin feels a great sense of security. At the same time, he can''t help scratching his head. Now the defense of the gate is enough, but the wall is not as strong as the gate.


    However, there is no need to worry too much about this problem. After all, his refuge is underground, and above his head is a mountain more than 200 meters high. The hardness of the thick soil layer will not be much worse than that of metal after freezing. If you want to dig up the frozen soil layer, it will be impossible to rely on manpower.


    So now as long as Chen Xin doesn''t open the door, no one will want to enter his refuge.


    The hydraulic lifting structure of the gate ensures the reliability of the gate, but if there is no electricity, it''s a bit hard to open the gate.


    Fortunately, the hydraulic mechanism of the lifting column of the gate has an emergency door opening device. If necessary, the liquid inside can be directly discharged to make the lifting column fall instantly and open the gate.


    But this is an emergency measure that can only be used once. It can only be used in the most critical moment or when necessary, because once it is done, the door will be closed again.


    With such a solid and reliable gate and Markham installed on it as a defensive weapon, Chen Xin is completely relieved of his own safety.


    After returning to the shelter and sitting on the sofa in the living room, Chen Xin had enough time to think about the whole story.


    First of all, the beginning of the incident should be the attack on No. 2 shelter in Baling County, that is, the mission in which Qin Lan was injured.


    Because in this incident, the terrorists who attacked the shelter used suicide attacks, resulting in more than 20 casualties, which attracted the attention of the city government. An investigation team was set up to investigate. Chen Xin''s first encounter was also at that time.


    Later, the provincial government, which received the notice from the municipal government, was also shocked by the incident. So it sent a special investigation team from the provincial capital Xingcheng to the city, and formed a joint investigation team with the investigation team of the city, and then launched a second trial.


    According to Qin LAN, it is very likely that the municipal government had an important clue in the first Mopai, and determined that the terrorist who made the attack was in the area where Chen Xinjia was. Therefore, the second Mopai still included Chen Xinjia.


    But there is a doubt, because Qin Lan was injured, Ding Ning was sent to take care of her, and the two were given a month''s leave. This happened after the attack and before the municipal government set up an investigation team to carry out the rehearsal.


    "Uncle Ding and the special police team knew in advance that it had something to do with me?" Chen Xinmo rubbed his chin and always felt that something was wrong here.


    According to the truth, even if Uncle Ding wants Ding Ning and Qin LAN to protect themselves, it should be the first time to make such a decision when he determines that the terrorists are in his own area.


    But Uncle Ding gave Qin LAN and Ding Ning a month''s leave at the beginning, as if he knew in advance what would happen, and then deliberately gave Ding Ning and Qin LAN a reason to support them.As for the note given to him by Ding Ning, Chen Xin thinks it''s quite normal. After all, it''s the second time that the arrangement is over. If we want to arrange any action, we should have enough clues and intelligence.


    It''s just that uncle Ding always loves Ding Ning. In order not to let Ding Ning be in danger, he gave her a holiday before the disaster and asked her to go to Mo Qingyan


    When Chen Xin thought of the holiday, he had inspiration and connected several things.


    Before the attack, as the captain of the special police team, uncle Ding probably received intelligence or clues from some channels, but he did not know the time and place of the attack, or that the attack would cause so many casualties.


    So at this time, Ding Ning and Qin LAN are all at work as usual.


    With the time of the attack, Qin Lan was injured, and more than 20 police officers of the special police force and the armed police force were injured or killed. All of a sudden, things became worse.


    So at this time, uncle Ding took advantage of Qin Lan''s injury and sent Ding Ning to take care of her, and directly gave them a month''s leave, which should be intended to let them stay in the relatively safe place of the hospital.


    This is why Ding Ning didn''t give the note to himself at the beginning, and didn''t say anything about moving in with Qin LAN.


    But with the two investigations, it is obvious that something happened that Chen Xin did not know, which led to the change of things.


    Ding Ning''s note is handed over to him at this stage. Obviously, uncle Ding''s original arrangement has changed.


    This may be a sign of what big action the joint investigation team is going to carry out, otherwise uncle Ding can''t put his daughter here, which is likely to be in a refuge within the scope of terrorist activities.


    However, this is not necessarily. Chen Xin''s fingers are hitting his knees. After straightening things out, he has a lot of clear ideas and new judgments.


    What he analyzed just now are the thoughts of the police and the joint investigation team. But if we take the perspective of these terrorists, Chen Xin thinks that they may not come to his refuge.


    Because although terrorists are crazy, they are not crazy. Since they can attack official shelters at the cost of more than a dozen lives and make suicide attacks, they must have their own goals.


    No matter what the target is, the suicide attack is likely to be just the beginning, because for terrorist organizations, more than a dozen people who have been strictly trained and dare to launch suicide attacks are also very valuable, and can not be wasted so unintentionally.


    So the first attack they made is likely to attract the attention of the police and the city government.


    Assuming that their goal is achieved, now the attention of the municipal government and the police has been attracted to baling County, it means that the attention of the municipal government and the police to the urban area has declined. Under such circumstances, if terrorists want to launch the next attack, where will they choose?


    Chen Xin thinks the answer is obvious.


    Thinking of this, he can''t help worrying about his friends in the city, especially Mo Qingyan and Mo Qingxin, who lack strong enough defense and have little resistance. If anything happens, they really have no ability to deal with it.


    Why don''t you let the two of them come here and stay away for a while?


    Chen Xin considered the idea, but hesitated.


    On the one hand, Mo''s sisters may not be willing to come. On the other hand, if he wants to live with five people and four of them are girls, it will be very embarrassing for him.


    However, considering the possible danger, Chen Xin thinks that after Qin LAN and Ding Ning come, he should discuss with them before making a decision.


    Only in this way, where I live


    Chen Xin can''t help scratching his head, and finally upgraded the bedroom. As a result, does he still want to sleep on the sofa?


    But it''s all later. Now Chen Xin thinks that he should be ready for Ding Ning and Qin LAN to come and live. After all, they are two girls. Some things still need to be prepared.


    This inevitably makes Chen Xin feel in trouble, but the arrival of Ding Ning and Qin LAN can''t be said to be no good. At least they are two people who can work. Although they only live temporarily, they can help themselves to share a lot of things in the shelter.


    At least there are a lot of things in the greenhouse. Now someone is helping. Chen Xin doesn''t have to be busy from morning to night.


    And the shelter with other people, also can be lively, some people with their own chat, night break time can also play games together.


    To tell you the truth, it''s good to play games alone, but it''s better to play with others.


    Thinking of these, Chen Xin can''t help but look forward to the arrival of Qin LAN and Ding Ning.

 Chapter 186

    Qin LAN and Ding Ning arrived later than Chen Xin expected.


    However, they arrived at the door of Chen Xin''s house in a special car.


    Using the remote control to open the door after the new upgrade for the first time, watching the heavy metal door slowly fall and the cold wind pour in, Chen Xin''s heart is also filled with an unspeakable flavor.


    He felt as if he was a big boss or a villain in the bunker. He didn''t look like the protagonist at all.


    After all, in the movie, the door opens like this, and most of the people behind the door are not the protagonists or positive characters.


    But it''s just a bit of random thoughts. As the gate drops completely, looking at Qin LAN and Ding Ning coming down from the car at the gate, Chen Xin takes a few steps forward and welcomes them.


    But the snow at the door is a little deep, half a meter deep, so that Ding Ning and Qin LAN can''t come down directly.


    "What a cool gate Ding Ning jumped down from the snow on the door with his bag. After he turned around and helped Ding Ning down, he asked Chen Xin, "but last time I came here, it didn''t seem like this, did it?"


    "I''ve made some improvements. The old push-pull gate can''t be opened when the snow is thick. It''s much better to replace it with the current lift gate." Chen Xin explains to Ding Ning, and at the same time looks at Qin LAN: "ah LAN, are you here?"


    Qin LAN nodded slightly to Chen Xin and answered in a soft voice: "well, this period of time is disturbing."


    "It''s too late for me to be happy that you can come." Chen Xin answered with a smile and looked up at the person who sent them outside. Although he was a young special police officer Chen Xin didn''t know, he still said to each other, "comrade, please send them here. Come in and have a drink."


    But the other party shook his head and said, "no, I have other things to do. I need to go back to the city right away."


    With that, the other side handed down a large black luggage bag and a long box, said hello to Ding Ning and Qin LAN, then turned to get on the car and left.


    Watching the other party leave, Chen Xin didn''t care, so he closed the door again.


    When the door closed, he looked at Ding Ning and asked her, "Xiao Ding, what did you mean by that note before? What''s going on? "


    "There is a big action in the Bureau, you need to cooperate with ah Xin. Sister LAN and I are here to protect you." Ding Ning quickly explains, but also looks at Qin LAN, indicating that she continues to explain, while she quickly opens the bag and checks the contents.


    Chen Xin has no choice but to turn his head and look at Qin LAN, waiting for her explanation.


    "Ah Xin, do you remember the father and daughter who froze to death in front of your house?" However, Qin LAN did not directly explain, but asked a seemingly unrelated question.


    "Father and daughter frozen to death at my door?" Chen Xin was a little surprised, but he still nodded. After all, such a thing is really hard to forget.


    Seeing that Chen Xin remembered the incident, Qin LAN continued: "the father and daughter escaped from a private shelter nearby. It was originally built by them and other relatives before the disaster, but they were occupied by the terrorists who attacked No. 2 shelter in Baling county. They escaped for help. It''s a pity..."


    Chen Xin knows what Qin LAN is pitying for. After all, the father and daughter froze to death at his door.


    But Chen Xin still felt a little strange and asked Qin LAN, "how did the police know about this?"


    "In the little girl, we found a mobile phone. After opening it, we found the pre recorded video in it." Qin Lan''s mood is not high. She doesn''t know whether she has just been discharged from the hospital or because she thinks of her dead comrades in arms. But she goes on: "the video is secretly recorded, which shows the origin of the terrorists who occupy their refuge and their plan to attack the important facilities of the city government."


    At this point, Qin LAN obviously stopped for a moment, adjusted his mood, and then continued: "after the shelter was occupied by terrorists, they were not killed by terrorists, they were just controlled. But the little girl''s parents still tried every means to escape. With the sacrifice of the little girl''s mother and the cooperation of other relatives, they escaped. They thought ah Xin was the official refuge here, so they came to knock on the door, but they didn''t expect It''s freezing at your door. "


    "This That''s unfortunate. " Chen Xin sighed, if only he had installed a doorbell at the door.


    Maybe this topic is a bit heavy. Qin LAN quickly jumps over this paragraph and continues to introduce: "the attack happened later. When I was injured in the hospital, the city bureau had already launched an operation and sent someone to the shelter, but The terrorists have left, and all the people in the shelter have been killed. "


    Listening to Qin Lan''s introduction, Chen Xin''s scalp is numb. It doesn''t really feel that there are terrorists in the game or TV news. But if this kind of thing changes to reality and happens around him, it will inevitably make people feel creepy and scared.


    "Who are they? Why do you do that? " Chen Xin calms down and asks Qin LAN a key question.For this question, Qin LAN did not answer, but looked at Ding Ning who was still checking the equipment: "ah Ning, come on, you know better than me."


    This time, Qin LAN and Ding Ning brought a full set of special police combat equipment, including helmets, bulletproof vests and a series of equipment, while the long box contained Qin Lan''s sniper gun.


    These equipment are obviously disguised as the luggage of Qin LAN and Ding Ning. Ding Ning was just checking and sorting.


    Hearing Qin LAN calling himself, Ding Ning stood up and explained to Chen Xin, "ah Xin, do you know that this city is located in the northern end of Hunan Province, bordering Jiangxi Province and Hubei Province?"


    "Of course, I know that. In the past, because this city belonged to the junction of the three provinces, although it was an important transportation place connecting the three provinces, because of mountainous land and difficult water transportation, it almost belonged to the area where the three provinces met. It was not improved until the founding of the people''s Republic of China." Chen Xin recalled that he had checked the city''s materials for writing novels in the past, and naturally spoke out smoothly.


    Although this city is an important land and water transportation place, connecting not only the three provinces, but also the north and south of the Yangtze River, there are many hills and rugged terrain here. Because of the hilly landform, the winding Yangtze River has nine turns and eighteen bends here, and the hidden reefs and beaches, which is not a good place to go in ancient times.


    The 240 km long waterway is only 80 km in straight-line distance, with 16 bends, which is called "nine twists and turns". Even in ancient times, this section of the Yangtze River waterway within the jurisdiction of the city had the saying that "the Yangtze River is ten thousand li, and the danger lies in Jingjiang".


    That is to say, after the founding of the people''s Republic of China, in order to get through this section of waterway, the state specially built a bend cutting and straightening project, straightened the Yangtze River waterway, and blasted off the reefs at the bottom of the river, so that this section of Yangtze River waterway was unblocked.


    As for the land, because Yanguo has been vigorously promoting the national infrastructure construction in recent years, and highway after highway has been built, Chen Xin still doesn''t feel much about the land road.


    But when you think back to the section where you drive through the junction of the three provinces, the mountains and hills and the bridges and tunnels, you can imagine how hard it was to walk here in the past.


    "Ah Xin, since you know this, it''s easy to explain." Ding Ning nodded and praised Chen Xin''s knowledge before continuing to explain: "because this city used to belong to Sanwu. Although there were not as many bandits as in Xiangxi, the boundary was not peaceful. Some historical problems still had some influence even after so many years. Therefore, in some remote mountain villages of Baling County, there are still some people related to Bailian religion It''s my faith


    ¡°WhattheF**k£¡¡± Chen Xin was stunned by the news that Ding Ning said. What he blurted out was the English national curse.


    However, Ding Ning and Qin LAN both understand why Chen Xin has such a big reaction, because the white lotus sect is so old that everyone can hear the name in novels or folklore. For network writers like Chen Xin, it is the excellent villain material in many novels.


    But in reality, the white lotus sect has really become the villain''s material, which Chen Xin did not expect, especially today there are still white lotus sect activities, which is really incredible.


    "At the beginning, we didn''t believe it as much as you did, but according to the clues collected, these people are really related to the Bailian sect. They belong to the Bailian branch that survived from the tartar Dynasty and have been handed down in the remote mountain villages of Baling county all the time." Qin Lanchong gave Chen Xin a bitter smile. She didn''t expect that she would be right. Those terrorists were really evil cult.


    Chen Xin pinched his nose and relieved his mood. Then he continued to ask, "but since they have existed since the end of the Qing Dynasty, didn''t the municipal government know it before? In the past, when we broke the four old ways and fought against feudal superstition, we didn''t get rid of them? "


    "Of course, the city government has cracked down on them, but it just makes them turn from light to dark. Their faith has been rooted for one or two hundred years, and they are quite deep-rooted." Ding Ning shook her head helplessly. When she heard the political commissar talk about it, she also had the same reaction as Chen Xin: "in addition, they basically abide by the law. The Bailian cult worships Maitreya Buddha, which is very hidden and difficult to eradicate. The city government just keeps one eye open and one eye closed. It''s mainly because they don''t make a big noise, so they go with them."


    "But no one thought that the coming of the end would be an opportunity for those people to make such a big deal." Chen Xin summed it up with a bitter smile on his face.

 Chapter 187

    "No matter how they come in, why do they come to this city to make trouble? This is the hinterland of Yan state. It''s not a place like Southeast Asia. Aren''t you afraid of being suppressed by iron fist? " Help Qin LAN to carry her things to the shelter, Chen Xin asked the heart of doubt.


    high streets and back lanes are all the most important questions in Chen Xin''s mind. The state is not only strict with the guns but also the public security. The streets are all covered with cameras before the disaster. The strict registered residence management system can even trace every person''s whereabouts.


    That is to say, after the disaster, the original social order of the country collapsed, coupled with the bad environment, the government''s control over the country declined. Otherwise, they would have been found out and arrested by force.


    So Chen Xin wondered why a group of mercenaries from Southeast Asia came all the way to Hunan Province in the hinterland of Yan state.


    "Because the core of this group of mercenaries are from this city." Ding Ning explained to Chen Xin.


    Qin Lan was injured in the hospital before and didn''t know much about it, but Ding Ning had a more detailed understanding of the situation because of her participation in the mission.


    "According to the information we have, the head of the group of mercenaries is the local people, and several key figures with him are also the companions who went to Southeast Asia with him at the beginning." Ding Ning continued to explain to Chen Xin, saying what the police had at present: "before the disaster, they had been wandering in Southeast Asia, not to mention committing all kinds of crimes, but there was no taboo in killing and setting fire. They were mainly employed by local warlords to fight for them and train their troops.


    With the advent of the disaster, the order of the whole Southeast Asia collapsed. A large number of refugees swarmed to the border at that time, intending to enter China for refuge. A considerable number of them crossed the border. These people should have entered China at that time.


    As for why they come back to the city, it should be related to the fact that they are from the city. Maybe they still have relatives and friends in the city. But we haven''t figured out the specific situation. After all, it''s no better now than before. Even if we want to make a large-scale search, we can only investigate the official shelters and the private shelters that have mastered the location. If someone really wants to hide, it''s hard for us to find them out. "


    At this point, regardless of Ding Ning''s frustration, if the police really wanted to find these mercenaries before the disaster, it would be much easier than now.


    Before the disaster, the Skynet system, which was composed of monitoring systems all over the streets and alleys, was the most grassroots community cadres and village cadres in the state of Yan. They could also get a clear picture of the situation in their respective areas of jurisdiction, to every household. As long as they started, they could find out these mercenaries.


    Chen Xin also understood this truth, but he didn''t say anything more. He just took Qin LAN and Ding Ning to the bedroom prepared for them. After putting down their luggage, he introduced them: "this is a room specially made for you two. The conditions are limited. If there is anything inconvenient, please remember to say it in time."


    "Ah Xin, you are very polite. The conditions here are very good. Even before the disaster, it is difficult to find such a comfortable room." Qin LAN quickly responds to Chen Xin''s polite words, and at the same time says with some apology: "we''ve come here to give you a new trouble."


    She came to Chen Xin and lived here for a period of time. She also knows something about the situation here.


    In front of her, the room looked clean and tidy. She didn''t have it when she came last time. It was obvious that Chen Xin had prepared it for them this time.


    This can not help but let Qin LAN feel that he and Ding Ning come to live, is to add trouble to Chen Xin.


    Chen Xin shook his head and said with a smile: "nothing. You come here to protect me. It''s also right to clean up a room for you. You put your things away first and have a rest. You''ve been here before. I''m in the greenhouse. If you have anything to do, please call me."


    With that, Chen Xin turned and left the room.


    As Chen Xin leaves, Qin LAN and Ding Ning pack their luggage. Although the bags they bring contain their equipment, they also bring some clothes and personal belongings.


    "Elder sister LAN, you''re not well hurt. Just sleep below. I''ll sleep on the upper berth." Ding Ning took a look at the high and low bed in the room and directly threw his things onto the upper bunk.


    Seeing this, Qin LAN had to nod her head and didn''t say much.


    Although the wound on her shoulder has healed, it is not complete. Climbing up and down will still have an impact on her.


    Although in Qin Lan''s own opinion, this has not been a big obstacle, will not hinder her action, but Ding Ning is not at ease to let her climb up and down.


    Two people put the luggage, dingning this just sat down with Qin LAN, discussed this task.


    "Sister LAN, how do you think we should carry out this mission to protect ah Xin?" Although Ding Ning has a clear understanding of this task, she was just an ordinary grass-roots policeman before and did not do this kind of job of protecting people, which makes her not know where to start this task.


    Ding Ning didn''t know what to do, but Qin LAN didn''t have the experience.


    She is a special police officer, but she has never carried out the task of protecting others. At this time, she can only rely on her experience and say: "first, find out the surrounding environment There''s nothing to find out about the surrounding environment. As long as ah Xin doesn''t go out, I don''t think those terrorists can get in. "When she came in, she noticed Chen Xin''s gate. The heavy gate was as strong as a metal wall, not to mention a mercenary. Qin LAN felt that even if all the special police officers went out and brought all the equipment, they might not be able to break the door.


    That''s not something that light weapons can handle.


    "The main thing is to understand some basic information about ah Xin and see if there are any defense loopholes." Qin LAN can only say this at this time. After all, she doesn''t realize that Chen Xin has any loopholes here: "as for him, if he wants to go out, we can follow him, but we''d better avoid going out as much as possible."


    Listen to Qin LAN say so, Ding Ning can only nod. After all, for Chen Xin''s refuge, there is no way to come in except to attack his heavy and solid door.


    However, Ding Ning''s thinking was a little bit out of the way. When she said this, she also thought of some other questions: "in this case, in case the terrorists call, how can we defend? You can''t just hide behind closed doors and call for reinforcements? That''s too much for me


    "Isn''t it good to finish the task simply?" Qin LAN looked at Ding Ning and laughed, but still thought about it and said to her, "ah Xin has built an observation room above his gate, where he can go up through a secret door. It''s a small room similar to a blockhouse, where he can arrange a firepower point. If someone attacks, it''s also a means of counterattack."


    Hear Qin LAN say so, Ding Ning this just happy: "no wonder elder sister LAN you want to take the sniper gun, if there is a blockhouse, cooperate with elder sister LAN you this top sniper, how many people are free!"


    Ding Ning''s words didn''t make Qin LAN happy. She just shook her head and touched her injured shoulder. A slight tingling came to remind her that she hasn''t fully recovered.


    The injured shoulder is the left shoulder, and Qin LAN usually used to shoot with his left hand. When using the sniper gun, the butt of the gun is naturally on the left shoulder.


    Shoulder injury will undoubtedly affect her shooting, although it is not unbearable if it is really necessary.


    Seeing Qin Lan''s action, Ding Ning asked: "sister LAN, your wound hurts again?"


    "No, just a touch." Qin LAN shook his head and said to Ding Ning, "ah Ning, go and see what ah Xin can do for you. We are going to live here for a month. How can we help ah Xin do what we can? It''s impossible to say that we live here and do nothing? "


    "Well, I know. I''ll go to find a Xin. Elder sister LAN, have a good rest first." Ding Ning nodded, then got up and left the room.


    Watching Ding Ning leave, Qin Lan also stood up and put the long box on the table of the room.


    Sitting on the chair in front of the table, she reaches out her hand to open the box. Looking at her beloved sniper gun in the box, Qin LAN can''t help but gently touch it.


    The cold touch from her fingertips made her feel at ease. At the same time, there was a faint reluctance.


    This is her weapon. Last time she failed to use this gun to stop the terrorists from making suicide attacks, this time she will never let the same thing happen again!


    Thinking like this, Qin LAN held back the stabbing pain from his shoulder and assembled the sniper gun with both hands.


    Although it was slower than before, Qin LAN felt that it was still acceptable when she put her right shoulder against the butt of the gun and practiced aiming.


    If shooting with the left hand does have an impact, try to switch to the side that has no impact. Since you are here to protect Chen Xin, you should restore your fighting capacity as soon as possible to ensure that you can protect him.


    While Qin Lan was loading his gun, Ding Ning also came to the greenhouse. Chen Xin was watering the upland rice seedlings in the field.


    Looking at Chen Xin''s action, Ding Ning said hello to him and then asked, "sister LAN asked me to help. Is there anything I can do?"


    "Help? For the time being, there''s nothing special to help. It''s just watering. I''ll be able to do it by myself. " Chen Xin shook his head, but he still said to Ding Ning: "but ah Ning, you can help me do something else."


    "What''s the matter, you say? It''s on me." Ding Ning looked at the green greenhouse in front of him, patted his chest and assured him that he was eager to try.

 Chapter 188

    The arrival of Qin LAN and Ding Ning adds a lot of popularity to Chen Xin''s refuge.


    After all, he was the only one. If he didn''t speak and make any noise, the whole shelter would be very quiet.


    Therefore, although the operation of the generator and ground source heat pump will produce a lot of noise, Chen Xin has never considered eliminating the noise or making sound insulation, because the sound makes him feel that he is not living in a tomb, and he will not feel too quiet and fall into claustrophobia.


    However, the arrival of Qin LAN and Ding Ning also brought other influences on Chen Xin''s life. At least now Chen Xin has to make three portions of breakfast.


    "Xin, do you eat this in the morning?" Ding Ning looks at Chen Xin making breakfast, can''t help but ask strangely.


    It''s not that Ding Ning thinks Chen Xin''s breakfast is not good, but that he is too extravagant.


    Fresh rice porridge, which can also be said to be Chen Xin''s own kind of rice, and in the field to pick up this, how to eat it does not matter.


    But the sliced Iberian ham he put aside made dinning feel a little unacceptable. Even before the disaster, few people would eat breakfast like this, which was really luxurious.


    "You mean this Iberian ham? This is a gift given by Bruce Lee before. The quality of Ham will decline if it is kept for a long time. Moreover, since I have opened it, I can''t keep it for a long time. " Chen Xin explained, looking at the porridge in the pot has been almost cooked, so he turned off the stove and put the breakfast on the table.


    Put breakfast, Ding Ning also brought chopsticks, three people this just sat down to eat breakfast together.


    "It smells good!" Although Ding Ning said that she felt luxurious, when a piece of ham came into her mouth, she couldn''t help but utter tut Tut''s praise.


    Qin LAN is to appear quiet a lot, no matter how to say before she was in hospital, Chen Xin every day to send the sick rice have these, although she still feel very delicious, but also not like Ding Ning so cry out.


    However, while eating breakfast, Qin LAN inquired Chen Xin: "Xin, what can I do for you? Although we''re here to protect you, it''s not as if we''re living here for nothing. If you need any help, just ask


    One side of Ding Ning also hastily nodded his head, busily echoed: "yes, yes, if there is anything we can do, just say, don''t like yesterday, say so formally, the result is just let me help you water."


    "If you want to talk about things, there are some, but I have finished the relatively tedious and heavy work a few days ago, such as plowing, seedling raising and transplanting. If you came a few days ago, you would have been busy." When Chen Xin heard that they wanted to help, he thought about it for a while and then explained, "it''s relatively easy these days. The rice in the field only needs watering, and the vegetables in the hydroponic plate basically don''t need to be cared. Just let it grow by itself."


    "But we can''t do nothing, can we? It''s like we''re here for free. " Qin LAN still hopes to help Chen Xin do what she can.


    Seeing Qin Lan''s insistence, Chen Xin thought about it and said, "in that case, there is something you can do for me, ah LAN."


    "What''s the matter?" Qin Landun stayed up.


    Chen Xin smiles, taps her bowl with chopsticks, and says, "eat first, and then eat."


    breakfast was finished soon. After Ding Ning took the initiative to help clean up the dishes, Chen Xin took them to the oxygen generator of the shelter.


    There are five oxygen generators in Chen Xin''s refuge. In addition to the one in the living room, four are placed next to the generator.


    "This is the algal oxygen generator of the shelter, which is mainly used to provide oxygen for me. Because it''s a biological oxygen generator, algae leave a lot of sediment. " Chen Xin raised his hand and knocked on the green sediments at the bottom of the can. He said to Ding Ning and Qin LAN, "these sediments are all pure natural algae. The so-called health foods like Spirulina popular before the disaster are similar to these things. What I need your help is to remove the sediment from the tank and add it to the biogas reactor as raw material. "


    After Chen Xin explains, Ding Ning and Qin Lan also understand what he wants them to do.


    Chen Xin took a bucket and put it next to a valve at the bottom of the oxygen generator. He opened the valve and said, "this valve is prepared for extracting these deposits. As long as you open the valve, these deposits will be sucked out by themselves. Just use the bucket to connect them."


    As the water left in the valve carries the sediment out of the bottom of the oxygen generator, a large bucket of dark green liquid is soon added to the bucket.


    On the other hand, the dark sediments at the bottom of the oxygen generator were also discharged, which made it look much lighter.


    Chen Xin closed the valve, poured the green liquid in the bucket into another big bucket, then put the bucket back to the bottom of the valve and opened the valve again.


    "Because the valve is only used for drainage, so in this process, it can''t discharge all the deposits well at one time, so an oxygen generator needs to be discharged about three times." While explaining his practice, Chen Xin knocked on the bucket next to him: "although there is a lot of sediment in the discharged water, it is mainly water, so it is necessary to filter in this bucket and use the filter to remove all the sediment."With that, Chen Xin picked up a filter hanging on one side and fished it out of the bucket. The filter immediately had a layer of green algae.


    "Of course, you can also put the filter on the bucket, which can save a little work, but be careful not to get water everywhere." Chen Xin took out another bucket to scrape the algae from the filter net into the bucket, and handed the filter net to Qin LAN: "just put the filtered algae in this bucket. The biogas reaction tank is over there. There is a sign. Just open the lid and pour these things in. However, the taste is quite strong. It''s better to wear a mask when adding materials."


    "It sounds complicated!" Ding Ning couldn''t help but sigh.


    "It''s a bit cumbersome, so I''m thinking about how to transform it. I don''t need to be so cumbersome, but I don''t have any idea yet." Chen Xin nodded. In fact, he thought it was troublesome, but he was not in a hurry to improve.


    Qin LAN took the filter and tried to put it on the bucket to receive water directly, which quickly filtered out a lot of green algae.


    Then she turned to another bucket and said, "I''ll take care of this. Just filter out all the algae deposits, OK?"


    Chen Xin nodded, pointed to the sediment at the bottom of the oxygen generator tank beside him, and said, "just take out the sediment. After the bucket is full, go to the biogas reaction tank for feeding. You can cooperate with two people."


    Qin LAN and Ding Ning both nodded. The work just seemed a little more complicated. It wasn''t very troublesome and tiring. They could finish it quickly with their cooperation.


    "After the sediment is fished out, you just need to open the water inlet valve nearby to add water to the oxygen generator. The water doesn''t need to be filled too much. There is a scale on the jar. Just add it to that position." With that, Chen Xin turned around and walked toward the greenhouse, while Ding Ning and Qin LAN began to cooperate to discharge the sediment from the oxygen generator.


    When Chen Xin, Ding Ning and Qin LAN are doing their own work, the joint investigation team in the urban area is also holding a meeting to deploy the next action.


    "According to the clues we have at present, the next target of these terrorists will be the shelters in the urban area, but it is not clear which one is, so each shelter must do a good job in defense." In the conference room, a person who seemed to know that he was a senior official was speaking, and other people at the conference table were listening to him seriously.


    After the senior official finished his speech, a leader of the Municipal Bureau in police uniform at the conference table also said: "our Municipal Bureau attaches great importance to this operation, and has deployed capable forces to cooperate with the comrades of the armed police force to carry out joint defense and control of various shelters. Checkpoints and defense facilities have been set up at the gate of each shelter to ensure that everyone entering and leaving the shelter will be protected Check and don''t bring dangerous goods into the shelter. "


    "Our armed police will also cooperate with the Municipal Bureau to ensure the safety of every refuge." Next to the leader of the Municipal Bureau, an officer in the uniform of the armed police also made a pledge.


    The senior official who presided over the meeting nodded his head with satisfaction, but there was no expression on his face. These are basic things. If we do well, we should do well. If we do not do well, we will lose our jobs, or even lose our heads in this special period.


    Before the attack on No.2 shelter in Baling County, there was a vicious incident of suicide attack. The relevant personnel in charge of the management of No.2 shelter in Baling County, as well as the county government management of Baling County, were all punished. Some people were even investigated for responsibility, arrested and locked up, waiting for the liquidation after this incident.


    "Defense is not enough, we have to attack! We need to find these terrorists! Now let''s talk about the arrangement of the arrest operation The senior official who presided over the meeting set the tone, turned his eyes to the leaders of the Municipal Bureau and motioned him to speak.


    The leaders of the Municipal Bureau did not dare to neglect, cleared their throat and said: "after two large-scale investigations, we have now locked the terrorist activity area and are arranging the arrest operation..."


    The leaders of the Municipal Bureau introduced the arrest operation being arranged by the Municipal Bureau, and all the participants listened carefully.


    Just in the corner, an official of the municipal government was listening to the introduction of the leaders of the Municipal Bureau. At the same time, his eyes flickered, as if he was thinking about something.

 Chapter 189

    With the help of Qin LAN and Ding Ning, the work in the shelter is much faster than when Chen Xin was alone.


    With the joint efforts of three people, the work that Chen Xin had to finish in a whole day had already been finished in one morning.


    "I didn''t expect someone to help me. Things can be done so quickly. In this way, it will be OK in the afternoon." After lunch, Chen Xin couldn''t help sighing. Sure enough, it was easy for someone to help.


    Hearing Chen Xin say so, Ding Ning could not help but tease him: "ah Xin said so, it seems that he wants someone to stay! Do you want me and sister LAN to stay? Or do you just want sister LAN to stay alone? "


    Ding Ning''s words made Chen Xin and Qin LAN feel a little shy, but Chen Xin shook his head and said, "I want you two to stay, but it''s not convenient for you two to go to work, is it?"


    Although Chen Xin''s car upgrade is already in progress, considering the distance between Chen Xin''s refuge and the urban area, even if his SUV is upgraded to ATV and can drive them to work, it is still not a convenient choice.


    After all, even if the vehicle transformation is completed, driving out frequently in today''s environment is still a troublesome thing, not to mention, it is not a safe choice.


    So Ding Ning just joked. After Chen Xin said that, he skipped the topic.


    See Ding Ning skip this topic, Chen Xin also don''t think, three people still eat lunch, while chatting about other topics.


    "Xin, what are you going to do this afternoon?" Qin LAN takes the initiative to ask Chen Xin about the arrangement in the afternoon.


    She is not a leisure person, and now in this environment, nothing to do is a very tormenting thing.


    "I''m going to continue to fiddle with my car this afternoon and rebuild it." Chen Xin answers Qin Lan''s question and asks her the same question: "what are you going to do with Xiao Ding this afternoon? If you want to play the game, you can play the video game as you like. "


    In the face of Chen Xin''s politeness, Qin LAN shook her head and said, "just play the game. In the afternoon, I want to do some physical training. I''ve been lying in the hospital for such a long time before. I feel that the whole person is rusty."


    Chen Xin heard Qin LAN say so, also did not stop her idea, just told Qin LAN to pay attention to the wound, there is no more to say.


    On the other hand, Ding Ning said that he was very interested in the transformation of the car. He wanted to see how Chen Xin did it, and also called it personal protection.


    Hearing Ding Ning say so, Chen Xin didn''t stop her. After all, Ding Ning was also sent to protect him. It''s no problem not to worry about guarding him.


    After lunch, Ding Ning takes over the job of washing dishes, while Qin LAN goes back to her bedroom to have a rest and start the afternoon''s restorative physical training. Chen Xin sits in front of the computer in her bedroom and looks at the design of the car''s transformation. By the way, she turns on the monitor to check the situation outside.


    From the perspective of cameras, almost half of the gates of Chen Xin''s shelter have been submerged by snow.


    It''s not all from the snowfall in the sky. Although the city has abundant rainfall all the year round due to its proximity to the Yangtze River and Dongting Lake, with the further decrease of temperature, most of the newly formed snow now does not come from the sky, but from other places where it is blown by the wind. Everywhere is the remaining snow.


    This also reflects from the side how bad the weather is today. Without sunlight, the atmospheric cycle will lose its power source, which makes the climate worse.


    The vegetation on the surface was destroyed in the previous fire, and it is impossible to regenerate the vegetation in today''s environment. The wind has lost its obstruction and constraint, and it has become more and more violent.


    In this environment, human survival will only become more and more difficult.


    Perhaps now, because of the material reserves before the disaster and the fact that the national system is still in place, the vast majority of the people who survived can still guarantee their basic living conditions, or even further improve their living conditions. But this does not mean that everything has passed. The next step is post disaster reconstruction, and everything is developing for the better.


    Take this city as an example. At first glance, it seems that everything in this city is working normally. Except that the surface is uninhabitable and people have to live in underground shelters, everything seems to be recovering.


    The roads between the refuges are open, and the supply of food and materials is guaranteed. As long as people in the refuges in the urban area are willing to work, they will always have a meal to eat. Even if they are not willing to do dangerous work, they will not starve to death if they just look for jobs in the refuges.


    But the premise of all this is based on the fact that there is no problem in the material supply of the city.


    It''s a good thing to say that the city had granaries before the disaster and stored a large amount of food. After the disaster, the official planting areas and various shelters planted mushrooms, raised mice and bread worms, which can ensure food self-sufficiency to some extent. Although there are only a few kinds of food, it can at least ensure that people will not die of hunger.


    But other aspects of material supply is a problem, especially the supply of coal.The city is located on the Bank of Dongting Lake. Before the disaster, it was really close to mountains and rivers, which can be called beautiful scenery and beautiful environment. Chen Xin still remembers that his mother had a colleague from Northeast China who came to the city because he met the enterprises in the city to recruit workers at school and was attracted by the beautiful scenery of Dongting Lake and Yueyang Tower described in the poems.


    But no matter how beautiful the scenery is, it can''t be used as food, let alone firewood.


    Before the disaster, the city''s dense vegetation and forests may be used as firewood, but after the end of the natural disaster, there is not much to burn on the surface.


    In addition, there is no coal resource in the city, and all coal is transported by railway. Once the railway transportation is interrupted, the coal supply in the city will be cut off


    As long as the game players who have played in the ice age can imagine the consequences, in the case of minus 70 degrees, a large number of severe patients with frostbite and amputation will appear in one day, and people will be frozen to death in two days.


    Although underground shelters can protect against cold and keep warm, and block the invasion of cold, most of the coal transported into the city is transported to power plants for power generation in addition to heating.


    This is not the 18th century in the game. At that time, there was no large-scale use of electricity. Without electricity, life would not be affected. However, for modern human beings, without electricity, there is no coal in the steam age. All production and life would be affected or even stagnated.


    Especially now people live in underground shelters, ventilation, heating, lighting, cooking, boiling water It can be said that all aspects of life are extremely dependent on electricity supply, and large shelters need electricity to maintain the operation of oxygen generation equipment and planting.


    It can be said that once the external supply of coal resources is interrupted, depending on the city''s existing coal reserves, the temporary emergency may be able to support for a few days, but if the time is too long, causing a blackout crisis, it will not be three days before a large number of people in the city will die.


    For Chen Xin, after manufacturing the nuclear battery through the system, he has now got rid of the problem of electric energy. After all, no matter how high the energy consumption of his refuge is, it can''t reach the exaggeration of 150KW. He only needs to connect a nuclear battery in the power distribution room of his refuge to ensure the power demand of the whole refuge.


    However, Chen Xin does not feel that other people are the same as himself just because his current living environment is free from security threats.


    Now the smooth life in the urban area is just like a fragile soap bubble or a castle on the beach. It looks really beautiful, but when a big wave strikes, any crisis may destroy it.


    Chen Xin only hopes that he is worried, and that the city government has enough ability to deal with the crisis.


    Otherwise, just like this terrorist attack, if the terrorists are not going to attack the shelters, but use the gunpowder used for suicide attacks to destroy the railway, I''m afraid the city is in chaos at this moment.


    Thinking of this, Chen Xin''s face suddenly changed, and he stood up suddenly, with more and more worries in his heart.


    However, after thinking for a while, he sat down again. After all, this is a problem that he can think of. He doesn''t believe that people in the city government can''t think of it.


    Moreover, railway transportation is the top priority for the city and even the province, especially the materials transported from Hubei Province must pass through the city. If someone destroys the railway, it will be a nightmare.


    Therefore, Chen Xin thinks that the municipal government, and even the provincial government, should have done something to prevent this kind of thing, and it will not be so easy for people to damage the railway.


    Moreover, it is meaningless to simply blow up the tracks. It is just a matter of delaying a few hours for workers to replace the damaged tracks and sleepers. With the level of modern industrial infrastructure, it may take a little time to rebuild a railway, but if only a small section of damaged tracks is repaired, it will not take a few hours.


    But Chen Xin is still a little worried, so he leaves the room to find Ding Ning and tells her his worries.


    "So ah Xin, do you think those terrorists may damage the railway and threaten the safety of the whole city and even the whole province?" Ding Ning understood Chen Xin''s meaning, but the expression on his face was more serious than Chen Xin, so he had to confirm with Chen Xin repeatedly.


    Chen Xin also seriously said to Ding Ning: "no matter whether they are aware of this problem or not, since we have found this problem, it''s better to inform your father. Otherwise, if something really goes wrong, it will be serious."


    Hear Chen Xin say so, Ding Ning also nodded: "that I contact my father immediately."

 Chapter 190

    With the help of Chen Xin''s short wave radio station, Ding Ning got in touch with the Municipal Bureau and informed them of Chen Xin''s speculation and worries. He was at ease at last.


    Although I don''t know how effective my reminders can be, it''s better to remind than not to come, and it can also make me have a clear conscience.


    However, there are only so many things Ding Ning and Chen Xin can intervene in this matter.


    In the final analysis, both Ding Ning and Chen Xin are ordinary people. Ding Ning has the father of the captain of the special police team at most, while Chen Xin just picked up the plug-in of the system.


    But dingning special police team''s father to her care is also limited, it is impossible for her daughter regardless of the chaos, Dingshu also has no such right.


    As for Chen Xin, although he is really powerful in some aspects with the system, the problem is that before he got the system, he was just an ordinary person, and his foundation was so weak that he could not quickly use the system to enhance his own strength.


    At present, the biggest role of the system is to ensure that Chen Xin can live better in today''s environment, and he can not have the ability to interfere in other things.


    So after the announcement, Ding Ning and Chen Xin didn''t continue to pay attention to it. They just discussed it briefly. Chen Xin was busy with his afternoon work, and Ding Ning came to help him.


    Chen Xin''s vehicle transformation plan is on schedule, but at present, because the parts and materials promised by Li Yulong have not been delivered, Chen Xin can do very limited.


    And he doesn''t want to spend more money on the car before upgrading. Chen Xin doesn''t plan to upgrade the car again at this time. So although he said to Ding Ning that he wanted to carry out vehicle upgrading, in fact, Chen Xin is just dismantling and checking the car in front of him.


    After all, this car is not designed to run in such a bad environment. Although Chen Xin has driven out a few times in the past half year, the damage caused by extreme cold and dust is not small. Inspection, repair and maintenance are necessary.


    Although Chen Xin has never done vehicle repair and maintenance by himself, he can''t say that he drives his car to a 4S shop to do maintenance now, so he has to do it by himself.


    Fortunately, as a car owner, Chen Xin still knows how to judge and eliminate the basic faults.


    After opening the hood and looking at the dusty engine and other parts under the hood, Chen Xin took out a big brush and began to brush the dust on it.


    As for other more professional parts fault inspection, Chen Xin can judge which parts have problems with the help of the system upgrade interface. After all, in the system interface, if there is a fault, it will be displayed as "faulty XXX parts".


    However, although the dust accumulation is a bit serious, Chen Xin''s car is still in good condition, and it does not show which part is faulty.


    "Ah Xin, how are you going to transform your car?" Ding Ning plans to help, curious about how Chen Xin plans to transform the car.


    There is no fault in Chen Xin''s engine compartment. Previously, Chen Xin removed the battery and upgraded it to a nuclear battery. However, the upgraded nuclear battery is not the same size as the original battery, and its output power is also very different. Chen Xin can not directly install the nuclear battery as a battery.


    So Chen Xin had to spend another 500 survival points to upgrade the power system of the car, upgrading it from fuel power to electric power. Only then did he install the nuclear battery back, avoiding the dilemma that the car could not start because of the removal of the battery.


    But because Chen Xin didn''t want to waste the upgrade points, this upgrade only adjusted the power system, and didn''t make any other changes. Even the ash accumulation in the engine compartment didn''t decrease. It seems that this car has been like this for a long time.


    Because of the existence of information state concept fuzzy function, and the battery itself is not impressive, under the cover of dust accumulation in the engine compartment, it just looks like a gray part.


    For Ding Ning, who doesn''t know much about cars, she can''t even tell whether it''s a fuel car or an electric car. Naturally, she can''t tell the nuclear battery which has been blurred.


    "Ah Xin, how are you going to transform your car?" Ding Ning watched Chen Xin cleaning the engine compartment, so he stepped back a little to avoid dust falling on him.


    "At present, I''m going to change the wheels to crawler type, so it''s more convenient to drive in the snow. The tires are still too easy to get stuck in the snow." Chen Xin answers Ding Ning''s question while clearing away the dust.


    According to the standard cleaning process, the engine should be cleaned with cleaning agent after cleaning the dust inside the engine compartment with a soft brush. But now the conditions are limited, so Chen Xin can only clean the dust.


    When Chen Xin said that he wanted to change the wheel into a crawler, Ding Ning felt a little incredible: "is the crawler chassis totally different from the wheel chassis? How can this be transformed? "


    "What can''t be changed? It''s a pity that I didn''t buy that kind of track modification before the end of the day, otherwise there was no need to do this kind of modification at all. " Chen Xin cleaned up the dust in the engine compartment with a brush, and then closed the engine hood. He didn''t care about Ding Ning''s problem.However, Ding Ning was intrigued by Chen Xin''s words, and asked him, "what''s the change? What is that? "


    "A kind of thing called snow track wheel, which is a track structure, can be stuck on the wheel through the connecting mechanism, making the wheel become a track." Chen Xin explained to Ding Ning that he had only seen that kind of thing on the Internet. He wanted to buy it at that time, but he didn''t see it on sale in Yanguo.


    Ding Ning was very interested in this and pestered Chen Xin to ask him about this kind of snow crawler wheel: "what kind of thing is that? Xin, do you remember the structure? Can you do it yourself? "


    "I remember the structure, but I have to say that I made it myself..." Chen Xin is a little bit bothered by Ding Ning, but she still answers her question. She just wants to say that she can''t do it, but suddenly stops.


    It seems that with the help of the workbench of the system, can he make this thing?


    First of all, the structure of the snow track wheel is not complex. It does not replace the wheel like the traditional track system, so it does not need to modify the car''s transmission or replace the tire. It only needs to put the snow track wheel on the ground, then drive the car and clamp it on the wheel to complete the installation.


    Both of them have no power, but rely on the original wheels of the car to drive the track forward, so there is no complex transmission structure, let alone the design problem of the power system.


    Knowing the structure and principle, it''s not difficult to make a similar thing, especially for Chen Xin who has a system, it''s easier to make it.


    Ding Ning looked at Chen Xin, stunned, and then pushed him: "ah Xin, what are you doing? Can you make this? If you can do it, I think the demand is still quite large. You can exchange materials with my dad after you do it.


    A lot of cars in the bureau are a bit crouching now. They can''t drive in the snow. It would be great if you could solve this problem! "


    Being pushed by Ding Ning, Chen Xin came back to herself, nodded at her and said, "I was just thinking about the structure of this thing. It seems that it can be made, but it''s not complicated."


    Chen Xin said, then took Ding Ning from the garage back to the refuge in front of the workbench, took out a piece of white paper and pencil, began to draw a sketch.


    Since it is called snow crawler wheel, it must be a crawler structure, so a crawler is essential, but there is no need to use metal crawler, rubber crawler is enough.


    While recalling the kind of snow crawler wheel that he had seen, Chen Xin outlined it on the paper, and Ding Ning also looked at it with interest, and from time to time raised some curious questions about Chen Xin.


    "Ah Xin, how did it get stuck on the wheel?" Ding Ning looked at the sketch gradually drawn by the novice Chen and asked him curiously.


    Although Chen Xin drew the sketch and general structure of the snow track wheel, he still didn''t know how it got stuck on the wheel.


    After all, he has only seen pictures and videos, but not real objects. Therefore, what he draws on the paper is only what he remembers by feeling. If he wants to explain what is going on, he can only know by doing it.


    However, Chen Xin replied to Ding Ning with feeling: "it is used under the wheel, so it should be pressed by the weight of the vehicle itself, and it should be fixed on both sides of the part connecting the tire, which should also be prepared to prevent it from falling.


    I''m not sure if it''s like this, because I haven''t seen the real object, and I''m just painting it based on my impression. So whether it''s good or not may be known only after it''s actually used. "


    Chen Xin said, while constantly improving the design, but also thinking about how to make things out.


    As Ding Ning said, if it can be made, it will be in great demand, because it can solve the driving problems of most vehicles with wheel chassis in today''s environment, instead of using more laborious ways to unload the wheels and replace them with tracks.


    Although it is a once and for all choice to replace the crawler system in today''s environment, since the underground passage has been built in the urban area, many cars still need to be driven by wheels. After all, the wear and tear of the track on the road is far greater than that of the tire.


    Therefore, this kind of track modification which can be easily disassembled is much more convenient and practical than the track system which needs to disassemble wheels.


    If he is not sure about the specific fixed structure, Chen Xin can only make one first, and then use the system upgrade method to determine its fixed structure. After all, it is impossible to fix it just by pressing the weight of the vehicle itself on it, as he said. In that case, it is very easy to fall off when you cross a ditch or ridge on rugged terrain.

 Chapter 191

    When Chen Xin was thinking about how to make snow crawler wheels, the atmosphere in the city became increasingly tense.


    Although the surface is calm, but in fact, under the surface of calm is ready to start the huge waves.


    At the gates of the major shelters, there are tight sentries set up by the city government''s management personnel, police and armed police forces to strictly check everyone who comes in and out.


    The management personnel are responsible for the identity examination to ensure that the identity of each person who passes through the gate of the refuge is well documented and has the residence certificate and pass issued by the city government.


    This is a management system implemented after the disaster. Although there was a pass and residence permit system before, the control was not very strict. Just like the ID card before the disaster, many people would not even take it with them. However, if we want to strictly check it, everyone must have it and be able to match the number.


    On the other hand, the police are responsible for security inspection to ensure that people entering and leaving the refuge do not carry dangerous goods or contraband. The armed police are responsible for maintaining the order of the scene. Suspicious elements are handed over to the police for arrest and detention. Criminals with the intention of sabotage or making trouble are arrested by the armed police, and the Protestant clergy can be directly killed.


    Under the close cooperation of the three, although we dare not say that there is no leakage, at least on the surface, it looks orderly, and criminals with ulterior motives can never fish in troubled waters.


    Most shelters are so tightly guarded, especially the one where the city government is located.


    As the current office location of the city government, it is also the residence of the joint investigation team. The soldiers of the joint investigation team from Star City are stationed here, so that the examination and defense at the gate of the city government is one level higher than other shelters, even if there are no flies now.


    However, despite the strict examination of entering and leaving the shelter, it is relatively easy and simple if you don''t come out and just stand at the gate of the shelter and smoke.


    Because the shelter is closed inside, it''s very troublesome to want to smoke.


    After all, smoking in a closed environment, if the smoke can not disperse, it will leave a very bad smell, and smoking in the shelter is also easy to cause fire and other safety hazards.


    Therefore, smoking inside the refuge is prohibited, but cigarettes themselves are not. It''s just that if you want to smoke, you need to come to the entrance of the refuge and smoke in a place with good ventilation.


    Considering the pressure of life in the doomsday environment and the fact that there are more people who are addicted to smoking, each shelter has designated a small area at the door as a smoking place.


    It''s just that the so-called smoking place is just a corner where the wind blows. Although there is no cold wind rolling up the ice and snow and slapping it on the face, standing for a cigarette is basically the limit. If you stand in this place for a long time, your feet will not lose consciousness, but will be frozen in the physical sense.


    But for smokers, it''s also a very rare enjoyment to smoke a cigarette in the current environment. Although cigarettes are very expensive, they need to spend a lot of food and materials on the black market, or they have enough contribution and work points to get a very rare package from the materials issued by the shelters every month.


    The same is true for the officials who have just held a meeting in the city government, especially for the boredom and brain drain brought by the long meeting. A cigarette can really refresh the mind.


    Although as the management, they are not lack of tobacco, but they still have to abide by the regulations to come to the smoking place at the door.


    Because the smoking place is located in the gate of the checkpoint, the police and the armed police in charge of the inspection only look this way, and they don''t pay much attention to it, and the staff are even less likely to offend their superiors.


    As a result, a few more smokers stood at the gate of the city government shelter.


    "Fortunately, I still have a cigarette here, otherwise I can''t stand the continuous meeting." It was a slightly rich official who spoke with a little star city accent, indicating that he came from the provincial capital.


    On the side, a city official who was also smoking couldn''t help echoing: "who said no! Now in this kind of environment, we can still have a few cigarettes to smoke, otherwise people can''t bear the addiction. "


    Several officials came out to smoke during the break of the meeting. At this time, they didn''t care about their identity or the difference between the provincial government and the municipal government. What they chatted about were also topics related to smoking.


    However, the time for a cigarette to burn was not long, and the break between meetings was also not long. Soon several people finished their cigarettes and were ready to avoid the difficulty and continue the meeting.


    Only one of them fell behind and didn''t seem to want to go in.


    This behavior naturally attracted other people''s attention. One of the officials asked, "Secretary Li, don''t you go in yet?"


    "I''ll finish this cigarette before I go in." The yelled man raised his hand and only smoked half of his cigarette, and laughed.


    Naturally, the person who asked him understood very well that a cigarette is very valuable now. It''s impossible to put it out after half of it.


    Other officials did not ask much. A group of people who had finished smoking went back to the shelter, leaving only Secretary Li, who was still smoking.But half a cigarette is also very short. When the others are almost gone, Secretary Li''s cigarette is almost finished.


    After the last two puffs, he threw the cigarette end into the garbage can.


    Just when Secretary Li wanted to go back, he found that the shoelaces on his feet were loose, so he squatted down and tied them again.


    When Secretary Li finished tying his shoelaces, he stood up and went to the shelter. When he met the cleaner who came to clean up, he nodded politely and said hello.


    The cleaner also politely greets Secretary Li. After he passes, he comes to the smoking place where a group of officials have just smoked, sweeps the cigarette ends on the ground, and empties the things in the garbage can into his own bag.


    There is nothing suspicious about this, so the police and armed police at the gate did not pay attention to this side. They paid more attention to the outside of the shelter and watched everyone in and out of the shelter warily.


    However, no one noticed that when the sanitation worker put the garbage can back, he had a note in his hand.


    The sanitation worker cleaned up the ground and then walked back to the shelter with his bag full of garbage.


    In Chen Xin''s shelter, Chen Xin soon finished the design of snow crawler wheels.


    The connection between the snow track wheel and the wheel is still a problem, but after some consideration, Chen Xin decided to add a chain on the bottom of the car and a fixing rod on the wheel hub to increase the fixing points. In addition, the clips on the wheel are used to fix the snow track wheel on the wheel, so as not to slip.


    As for no need, it''s easy to remove it. Just untie the fixing rod on the wheel hub and the chain under the car, fix the snow track wheel, and pull the wheel out of the snow track wheel.


    Looking at his drawings, Chen Xin feels that they should not be much different from the original. Even if there are some differences in structure and details, they are small things.


    The next problem, of course, is how to make it. Naturally, parts processing is not a problem. With the existence of a system, Chen Xin can easily get the parts he wants, but he still can''t make shoes without rubber.


    Rubber is a very common industrial material before the disaster, and all kinds of rubber products are also full of people''s lives.


    As an important industrial raw material, whether it is natural rubber from Southeast Asia or chemical rubber obtained through petrochemical technology, it is very easy to obtain before the disaster.


    Unfortunately, after the disaster, it is difficult to get rubber.


    In addition to the rubber raw materials left before the disaster, natural rubber is estimated to be gone. After all, even if those rubber trees have not been burned, now that the world has entered the ice age, those rubber trees have lost their growing environment, and no one is going to cut rubber.


    However, chemical rubber should be produced in the country. After all, it is a very important industrial raw material and should be used in all aspects. Even if the quality of chemical rubber is not as good as that of natural rubber, it is impossible to build a special greenhouse to grow rubber in today''s environment.


    According to Chen Xin''s estimation, the state should have preserved some industrial facilities and oil wells before the disaster. Relying on these preserved industrial facilities, production should have resumed after a little half a year.


    But now the transportation is in a state of half cut off, only railway transportation can go, the entire road network is almost paralyzed, even if the rubber is produced, it will be transported to the most needed place, and will not waste valuable production capacity and transport capacity to this city, which is a non key industrial city.


    Although there are many large-scale chemical plants in the city, which are important industrial production enterprises, in the previous disaster, the chemical plants around the city have been affected by the fire, and it is difficult to count how many equipment can survive.


    After all, the chemical plant itself is a flammable and explosive place. For Chen Xin, who grew up in the chemical plant, this can be said to be a familiar thing.


    Therefore, the industrial base of the city is almost gone now. Only the factory area under the jurisdiction of the city government can produce some materials needed for various shelters. Chen Xin can''t get these products without chemical rubber.


    So if Chen Xin wants to use rubber tracks, the only way is to get the rubber products that were left before the disaster, and use the system function to extract rubber that can be used as raw materials.


    And the most suitable rubber products, of course, are tires.

 Chapter 192

    For Chen Xin, in order to get enough materials, besides the extremely inefficient and dangerous way of picking up garbage himself, it is the simplest and direct way to get materials through Li Yulong.


    Originally, the SWAT team was also a very suitable partner, but now the SWAT team''s energy is focused on arresting terrorists, so naturally there is no extra energy to deal with the material exchange with Chen Xin.


    Previously, Chen Xin also revealed to the special police that he wanted to exchange more materials, but the reply he got was that he needed to postpone temporarily.


    This is obviously because the special police team has no way to allocate enough manpower to deal with this matter. It can only postpone this matter for the time being. Only after the terrorists have been dealt with can they have the time and energy to deal with the exchange of materials with Chen Xin.


    So Li Yulong became the only channel for Chen Xin to obtain materials.


    However, Chen Xin didn''t show this. After all, the group Friends of other survival groups can''t exchange goods and materials. It''s just that they can exchange too few goods and materials, and few people can arrive at his home to exchange goods and materials with him.


    After receiving Chen Xin''s request, Li Yulong moved quickly. He didn''t ask Chen Xinjiu to prepare the materials he needed and send them to Chen Xin''s home.


    In addition to the waste tires Chen Xin wants this time, there are also the auto parts that he and Li Yulong said were used to transform his car.


    "Brother Chen, I''ve brought you what you want!" Li Yulong still came here in person, while greeting Chen Xin, he flattered him and said: "for our hard work, can you make me a pair of snow crawler wheels first?"


    Listening to Li Yulong''s words, Chen Xin couldn''t help smiling and said to him, "your RV doesn''t need this, does it? And it''s not easy to make such big wheels and matching snow crawler wheels. "


    Chen Xin didn''t deliberately refuse Li Yulong. As he said, Li Yulong''s RV itself uses large snow tires, and the chassis itself is high enough. Even in today''s environment with more than one meter of snow on the road, it can drive smoothly, and there is little demand for snow crawler wheels.


    And large tires, naturally, should be equipped with large snow crawler wheels.


    Compared with ordinary car tires, which may be the size of ordinary people''s knees, Li Yulong''s RV is equipped with tires that can reach people''s chest. If such a large tire is equipped with snow track wheels, it naturally needs to be bigger.


    But to increase the size obviously does not mean to make it bigger.


    "How can this kind of thing be difficult for you, brother Chen?" At the same time, Li Yulong also said to Chen Xin, "I don''t want to experience how easy it is to use first! If it''s easy to use, it can also be our special product in the trading market, won''t it? "


    "Do you want to sell snow crawler wheels as commodities in the market?" Chen Xin listened to Li Yulong''s statement and rubbed his chin, but he didn''t object.


    A trading market, in addition to providing a trading platform for other vendors, has its own characteristics and other people can not copy the goods, is the key to attract more customers and vendors.


    Originally, what Li Yulong had prepared for the trading market was the ground source heat pump obtained from Chen Xin, which naturally attracted customers. But who would think that he had too many products that could make money?


    At least neither Li Yulong nor Chen Xin felt that way.


    Therefore, the two soon concluded a new cooperation agreement. Li Yulong provided materials and Chen Xin helped to make snow crawler wheels.


    Moreover, because Li Yulong felt that the technical difficulty of this thing was not very high, he also hoped that Chen Xin would teach his people how to make snow crawler wheels, and that they would learn how to repair them if they could not.


    After all, the snow crawler wheel is different from the ground source heat pump. Compared with the ground source heat pump, which doesn''t need too much maintenance after installation, the snow crawler wheel is a consumable.


    Although it doesn''t mean that it will be broken after one use, it''s normal to replace worn parts after a period of time.


    In particular, the rubber track used by Chen Xin is obviously worn and needs to be replaced regularly.


    As for Li Yulong''s proposal to teach his subordinates, Chen Xin nodded and agreed after considering it.


    However, Chen Xin did not say that he would teach them manufacturing technology, but only promised to teach them maintenance.


    Although Chen Xin didn''t agree to teach his staff manufacturing technology, it was very good for him to master the maintenance technology, so Li Yulong didn''t feel dissatisfied and readily agreed to it.


    Not only that, Li Yulong is also very enthusiastic with Chen Xin, want to see how he made the snow crawler wheel.


    Chen Xin didn''t mind Li Yulong''s following him. After his subordinates moved all the supplies and materials into his storeroom, Chen Xin sat down at the workbench and prepared to make the first pair of snow crawler wheels.Ding Ning and Qin LAN, who are staying here for the first time, naturally surround him. They are curious to see how Chen Xin makes things.


    In the face of three onlookers, Chen Xin didn''t care. He directly used the system interface to transfer out a waste tire from the warehouse and started the transformation.


    In the interface of the system, a worn-out tire that had been worn flat was quickly melted, and then deformed again. Together with the steel wire inside, it was woven into a new look. A rubber track component soon appeared on Chen Xin''s workbench.


    In Chen Xin''s eyes, we can naturally see how this used tire turns into a crawler component, but in the eyes of the three onlookers, Ding Ning, Qin LAN and Li Yulong, we can see how Chen Xin cuts off a used tire, flattens it, cuts it into a proper size, and then processes it into a crawler component.


    "Brother Chen, you are really skillful! You can play with a scrap tire in your hand Li Yulong couldn''t help exclaiming, even Ding Ning and Qin LAN couldn''t help echoing.


    For the praise of the three, Chen Xin didn''t care, Chong dingning said: "Xiao Ding, help me get the parts made there."


    Hearing Chen xinphen''s instructions, Ding Ning naturally helped Chen Xin take the parts he had made before and put them in front of Chen Xin.


    In addition to the track itself, the components of the track structure include driving wheel, load-bearing wheel, inducer and belt pulley. The driving wheel is a mechanism that transmits power to the track through the meshing of gears and track teeth.


    However, Chen Xin''s snow track wheel is just a track component, which does not need the driving wheel to provide power, so he did not design this part on the snow track wheel, only the load-bearing wheel, inducer wheel and belt pulley.


    As the name suggests, the load-bearing wheel is used to load and regulate the track; the inducer is responsible for guiding and supporting the track, and the belt pulley is used to support the upper track.


    In addition, although there are many supporting parts, the snow track wheel is not a tank track after all, and its structure is not so complex, so it is much simpler to make.


    As long as these wheels are assembled on the fabricated support, then the track components are assembled and installed on these wheels, and finally the fixed components are installed, a snow track wheel will be finished.


    Looking at the finished snow crawler wheel, Chen Xin felt that it looked rough enough.


    However, it doesn''t matter. After all, the crawler itself is associated with the impression of silly big black rough. As long as it''s easy to use, it doesn''t matter if it''s a little rough.


    This is also the consensus of Ding Ning, Qin LAN and Li Yulong, who are surrounded by Chen Xin.


    As long as it''s easy to use, why care if it''s rough or delicate?


    In this kind of doomsday, if we want to investigate whether the shape of something is beautiful or exquisite, we can only say that it''s either bad brain or too full.


    "Brother Chen, is this the snow crawler wheel? How do you use it? " Li Yulong looked at the snow crawler wheel made by Chen Xin and asked him curiously.


    Chen Xin knocked on the assembled snow track wheel in front of him and explained to the three people watching behind him: "through a pad, let the wheel clip into the slot, and then fix these fixings to ensure that the thing won''t slip. After that, just need the wheel to rotate and drive the transmission mechanism to make the track wheel move and drive the vehicle forward."


    "Wow, isn''t that convenient?" One side of Ding Ning issued a exclamation of admiration.


    Chen Xin nodded slightly: "although in terms of transmission efficiency, it''s not as powerful as directly removing the wheel and replacing the crawler structure, but in terms of convenient use, this kind of snow crawler wheel is much more convenient. It''s much easier to install it when you need to use it and unload it when you don''t use it."


    Listening to Chen Xin''s introduction, the three onlookers nodded. They didn''t understand everything. They naturally distinguished the difference between directly changing tires and installing this kind of crawler wheel. However, it was obvious that this kind of crawler wheel made by Chen Xin was more suitable for today''s use.


    After all, most of today''s vehicles are still wheel structures. It''s not only cumbersome and cumbersome to replace the wheel with a crawler, but also requires professional and technical personnel to operate it. How can there be such a kind of crawler wheel that just needs to be placed on the ground, and then it''s easy to drive the car?


    Seeing the production of the first crawler wheel, Li Yulong couldn''t wait to say to Chen Xin: "brother Chen, make the other three, let''s try the effect on them."


    Chen Xin heard him say so, also nodded, said to him: "to help me move a few waste tires."


    Hearing Chen Xin''s instructions, Li Yulong rushed to Chen Xin''s storeroom.

 Chapter 193

    A set of snow crawler wheels was soon finished and placed on Chen Xin''s worktable.


    Looking at the four snow crawler wheels, Chen Xin has nothing to say, but Ding Ning and Li Yulong are eager to try.


    "Brother Chen, why don''t you try it out? Now that it''s made, we have to try it out, OK? " Li Yulong said tentatively to Chen Xin with a few expectations.


    Chen Xin thought about it, nodded and said, "it''s better to have a try. Let''s have a try with my car to see if there''s anything that needs to be improved."


    Seeing Chen Xin''s agreement, Ding Ning and Li Yulong can''t wait to run to the gate of the shelter with two snow crawler wheels in their arms.


    Looking at the two people running up, Chen Xin and Qin LAN looked at each other and couldn''t help laughing at each other. Then they went up together.


    The installation of snow track wheel is very simple, just put it on the ground, put on two boards, and then drive the car up, using the weight of the wheel itself to clip the wheel into the groove on the snow track wheel, even if the installation is completed.


    So it didn''t take long for the newly made four snow track wheels to be installed on the wheels of Chen Xin''s car.


    Now that he has promised to try out the new equipment, Chen Xin has no nonsense. He asks Ding Ning and Qin LAN to change into protective equipment for going out. He also puts on protective clothing in the preparation room, puts a pistol in his pocket, and puts on a breathing mask. Then he opens the door of the shelter, sits in the car, and is ready to drive out.


    Qin LAN sat in the co pilot''s seat, while Ding Ning and Li Yulong crowded together in the back seat.


    Seeing that everyone had fastened their seat belts, Chen Xin started the car and drove towards the gate of the shelter.


    Part of the snow at the door has collapsed because Li Yulong''s men carried materials, which just provides a ramp for Chen Xin''s car to go out.


    If the car is not equipped with snow crawler wheels, it is not easy to go up even if there is a basically stepped down ramp facing the snow more than half a meter deep at the door.


    But with snow crawler wheels, everything will be different.


    Because the snow crawler wheel is added to the wheel, the original chassis of Chen Xin''s car has been raised a lot, which undoubtedly increases the traffic capacity of the vehicle through rough roads or roads like snow that are easy to sink in.


    The baffle installed in front of the snow crawler wheel can help the wheel to press on the snow surface, without directly sinking in.


    As the wheels turn, they drive the track. The whole car suddenly lifts its head and rides on the snow slope. Then it comes out with a burst of high-speed running of the engine.


    "It''s a good climbing performance!" Since Li Yulong is an SUV salesman, he naturally knows how to drive a car. When there were three extra people sitting on the car on the uphill just now, he was so relaxed, which was enough to show the climbing ability of the car.


    Chen Xin can''t help nodding: "the climbing ability of the crawler is better than that of the tire, the grounding area is larger, the friction is greater, and it''s not easy to slip."


    However, although he drove the car out, Chen Xin didn''t drive forward immediately. Instead, he parked the car at the door and said to the three people on the car, "wait for me. I''ll go down and check it. By the way, close the door of the shelter."


    With that, Chen Xin got out of the car. While closing the door of the shelter with the remote control, he turned on the flashlight and looked at the four wheels of his car to check the situation after the snow crawler wheels were installed.


    Naturally, there is no problem with the installation. The climbing performance just now is very good, which naturally makes Chen Xin very satisfied.


    However, the problem is that the snow track wheel is only a modified part, not a complete snow track component, and it still sinks in the snow.


    Although the subsidence is not much, only a few centimeters, it still makes Chen Xin aware of the problem.


    Compared with the professional snow track components, the grounding area of the snow track wheel is still not large enough, causing subsidence is inevitable.


    Of course, compared with the tire, the performance of the snow track wheel is very good, and this degree of snow subsidence can not bring any impact on the use of the snow track wheel, it can still run very smoothly, and hold the whole car firmly, won''t get stuck in the snow.


    After checking the connecting components and the chain under the car, Chen Xin came back to the car.


    "Ah Xin, is that ok?" Qin LAN, sitting in the co pilot''s seat, asks Chen Xin with concern.


    "The crawler is not wide enough, and it''s a bit sunken, but it doesn''t affect the use." Chen Xin shook his head and explained the situation to Qin LAN. Then he looked back at the two people in the back seat and asked them, "since it''s a test run, where do you think you should drive?"


    "Now in this kind of environment, it''s almost the same to drive anywhere?" Ding Ning thinks that there is snow everywhere now, and there is no difference in where to test.


    But Li Yulong had a different opinion. He thought for a moment and said, "why don''t you go to the high-speed railway station? It''s quite open there, so it''s good to try its performance. Even if you have to test the rugged road, there are mountains between here and the high-speed railway station. Mountain climbing is the best test. ""High speed railway station?" Chen Xin hesitated for a moment. Seeing Qin Lan''s approval, he didn''t say anything more. He stepped on the accelerator and drove towards the original high-speed railway station.


    From Chen Xinjia to the high-speed railway station, there was originally a road connection. Before it snowed, Chen Xin walked to the high-speed railway station and found a group of survivors.


    However, with the decrease of temperature and the accumulation of snow on the ground, the original road has long been unable to see clearly. What we can see is a little undulating snow.


    Driving in the snow, the snow crawler wheels run very smoothly, except that the noise may be a little bigger than just using tires, there is no other feeling.


    But the feeling of experimenting with a new thing still makes Li Yulong and Ding Ning in the back seat very novel and excited. After Chen Xin drove the car to a relatively open place, the two people also took the opportunity to propose that they want to experience what it''s like to drive a car with snow crawler wheels.


    Chen Xin doesn''t like it. After stopping the car, he and Qin LAN change to the back seat and let Ding Ning and Li Yulong sit in the front.


    The two men in order to fight who to open first, but also to a stone scissors cloth duel, the result Ding Ning won, was able to hold the steering wheel.


    Looking at the two people laughing in the front seat, Chen Xin can''t help shaking his head. If it''s before the disaster, this kind of picture is very common, but with the advent of the doomsday disaster, he hasn''t gone out with his friends like this for a long time, and he hasn''t heard such laughter for a long time.


    However, although the inside of the car is still very similar to the past, the outside of the car is still cold and dark with cold snow.


    Although with the memory of the past, and not far away from the statue which has not been completely submerged by snow, we can judge that this is the square in front of the high-speed railway station, it is obvious that the former square has been completely buried under the snow.


    Even the statue, which was more than ten meters high, has been damaged, leaving only a little base protruding from the snow and a broken statue.


    The high-speed railway station in the distance can only see a shadow standing in the wind and snow, and the shadow also collapsed a corner, which seems to be caused by a meteorite impact.


    High speed rail network is an important national transportation network built by Yanguo in the new century, which greatly facilitates the travel of Yanguo people, and even changes the travel mode of Yanguo people.


    However, compared with the traditional railway, the high-speed railway network built by Yanguo with huge investment is more dependent on the daily maintenance and the support of the modern civilization system. However, all this collapses with the fall of the end of the world, and the high-speed railway network also loses the most important support and becomes useless.


    The operation of high-speed railway is extremely dependent on electricity. After all, the high-speed train itself is an electric locomotive, and it can''t run without electricity.


    Therefore, the whole high-speed rail network is only useful for the railway tracks and high-speed rail stations. The original electric locomotive has not enough power to supply the whole high-speed rail grid in today''s environment, and there is not enough human and material resources to maintain the whole high-speed rail network.


    Chen Xin doesn''t know what''s going on in other places. Maybe some places can make one or two sections of high-speed railway run because of the need for use and their good conditions, but obviously the high-speed railway stations here in the city have been abandoned.


    After all, if only the use of rail, the original old rail will be enough to use, there is no need to spend more energy and resources to maintain the operation of the high-speed railway station.


    In particular, because the high-speed railway station in the city is built in the suburbs, the surrounding residents rarely do not say, and there is not enough underground space for renovation, unless a new shelter is built on the spot.


    So for the municipal government, it is not difficult to make a choice and judgment about the abandonment of high-speed railway station here.


    Looking at the abandoned high-speed railway station outside the window, Chen Xin can''t help sighing. He sighs for the high-speed railway network that Yanguo spent a lot of money to build, and for the collapse of prosperity and civilization.


    Just as Chen Xin sighed, a sudden dull sound came from his ear, just like thunder.


    This made him wake up quickly from the sadness just now and look at the other three people in the car. Ding Ning, the driver, also stopped the car in a hurry.


    "What happened?" Li Yulong was a little suspicious and looked out of the car window, hoping to find out what happened.


    "Isn''t it a meteorite? It''s very common now. It happens every few days in the city. It should be... " Ding Ning is a bit optimistic, think it should be the impact sound of meteorite falling down.


    However, before her words were finished, the next dull sound came again.


    This next Ding Ning and Qin Lan''s facial expression all changed, they obviously already reflected, this is not what meteorite impact sound, but the bomb explosion sound.


    "It''s a bomb!" Ding Ning called out, quickly turned his eyes to Qin LAN and Chen Xin in the back seat, and asked, "what shall we do?"


    "Drive back and don''t worry about anything." Chen Xin took a look at Qin LAN and said.

 Chapter 194

    None of the four people on the bus had the idea of meddling in their own business, and they didn''t want to watch the excitement.


    So after the attitude reached an agreement, Ding Ning hit the steering wheel, stepped on the accelerator to the end, and drove back to Chen Xin''s refuge quickly.


    Fortunately, the high-speed railway station is not far from Chen Xin''s refuge, and the four soon returned to Chen Xin''s refuge.


    After stopping the car and getting off, Li Yulong asked Chen Xin with a nervous face: "little brother Chen, what''s the matter? Is that really an explosion? "


    "It''s hard to say whether it was an explosion, but it''s certainly not the sound of a meteorite falling down." Chen Xin''s face was also very serious at this time. He thought about it and said to Li Yulong, "Bruce Lee, you''d better take your people back quickly. Remember to close the gate of the shelter after you go back. Don''t open the door if you have nothing to do, and call the police if you have something to do."


    "OK, I''ll listen to brother Chen!" Li Yulong didn''t have a big temper at this time, so he agreed directly.


    Chong Chen Xin reminded Chen Xin to pay attention to safety, and then returned to the city with his men who had been waiting outside Chen Xin''s shelter.


    Watching Li Yulong leave, Chen Xin also closes the door of the shelter.


    With the door of heavy nickel chromium alloy steel locked, Chen Xin was relieved.


    "Ah Xin, what do you think is going on? Could it be... " Qin Lan''s face is dignified and asks Chen Xin.


    As a special police officer, her professionalism has made her recognize that it was an explosion. In connection with the recent events, she naturally has a guess.


    Chen Xin looks a little hesitant. He is not sure whether the explosion was caused by the terrorists Qin LAN suspected, but he still says to Qin LAN: "it may be, so I will close the door for the moment. You and Xiao Ding had better not go out before confirming the safety."


    "All right." For Chen Xin''s decision not to go out of the shelter, Qin LAN answered positively, and Ding Ning nodded.


    Although for Qin LAN, she would like to bring the terrorists to justice and revenge for her comrades in arms, she is by no means reckless.


    Qin LAN clearly knows that she can''t fight against a group of terrorists by herself, and her current task is to protect Chen Xin, and she can''t leave Chen Xin''s side until she completes this task.


    What''s more, even if she wanted to go out and catch the terrorists, she didn''t know where to catch them before she knew what happened. The explosion just now was too abrupt to judge where the sound came from.


    The three agreed and went back to the shelter.


    At this time, Ding Ning grabbed Chen Xin and asked him, "ah Xin, what do you think was the explosion just now?"


    "It''s hard to say. There''s too much to fry." Chen Xin can''t judge what caused the two explosions just now: "it''s possible that terrorists are attacking the shelters in the city, the city government is encircling terrorists, and it''s more likely that terrorists are attacking other places There are too few clues to two explosions, and I can''t tell what happened


    "Then I''ll contact my dad and ask what happened?" Ding Ning''s first thought is her father as the captain of the Swat.


    Chen Xin shook his head slightly and stopped Ding Ning''s move: "wait a minute. If something really happens, uncle Ding is busy now. You can only make trouble for him if you contact him now."


    Hearing Chen Xin say so, Qin Lan also agreed and said: "yes, ah Ning, no matter what caused the explosion just now, even if it''s not a terrorist, the team is busy now. You contact the team leader at this time, and he has no time to say more to you, so we''d better wait and see."


    Seeing that Qin LAN and Chen Xin both said so, Ding Ning also gave up the idea of contacting uncle Ding immediately, but he was still worried about the situation in the urban area: "if only he could know what happened in the end."


    "It''s not that easy! There''s no radio in the city right now. " Chen Xin could not help shaking his head.


    It is reasonable to say that after the disaster, although the TV signal has disappeared for various reasons, there should always be broadcasting. But I don''t know why the municipal government has not resumed broadcasting, so that Chen Xin now has no channel to know some news.


    There was no new news, and even if they discussed it, they couldn''t get any results. At last, they casually talked about their own opinions, and they didn''t talk about the topic again.


    At this time, the encirclement and suppression of terrorists in the urban area has come to an end.


    Although the terrorists detonated the bomb at the gate of the city government''s refuge, because the city government had been on guard for a long time, the city government''s refuge gate was also heavily guarded. The bomb that should have been brought into the refuge and detonated was blocked outside the gate. Needless to say, the terrorist elements attacking the city government''s refuge were also jointly suppressed by the special police, armed police and the army.


    Although these terrorists showed a strong will to fight and were not afraid of death, they were short of weapons and were blocked at the gate of the city government''s refuge. Soon they were eliminated.


    Only a few survivors were specially left by the special police in order to obtain intelligence.Just watching his men clean the battlefield, uncle Ding and the commander of the armed police force look very ugly. Even the officers from the army on one side have the same black face.


    Everyone should be happy to have been able to eliminate the terrorists in this way. However, after the terrorists detonated the bomb in the previous battle, what came from afar was that although the railway promised to build the railway bridge in five and a half days, the municipal government still needed to prepare for the worst.


    "From now on, all departments must do their best to ensure that the repair of the railway bridge can be completed on schedule! At the same time, from now on, in addition to the necessary power consumption, all shelters have begun to take power rationing measures to reduce the power generation of power plants, so as to ensure that during this period, the coal for heating and the basic power generation of power plants will be used in all shelters. " The mayor made the final decision.

 Chapter 195

    Overall restrictions on electricity use will undoubtedly have a huge impact on shelters.


    Although the policy of phased water supply and power supply was adopted in the urban area before, which limited the power supply time, the power consumption was not limited during the power supply period.


    So a lot of people will charge their power storage devices in this period of time, so that they can use them after they stop the power supply.


    For example, every household is equipped with emergency lights for lighting, some electronic equipment saved before the disaster, some small household appliances that can be recharged These are the things that the survivors in the shelter need to recharge every day.


    The electronic equipment preserved before the disaster provided the few entertainment in the shelter, while the emergency light was the only lighting device for every household in this situation once the power supply was stopped.


    After all, it is forbidden to use open fire lighting such as candles in shelters. Emergency lights, which can provide lighting for a long time and can also be used as batteries, are very useful.


    However, now it has begun to restrict the use of electricity, and the use of various electrical equipment has been greatly restricted, which has also caused considerable panic.


    "What''s going on? How to stop using electricity all of a sudden? Is there no lighting for the power supply time? " One survivor, with obvious panic and worry on his face, asked the shelter''s management what was going on.


    "Yes, yes! What the hell is going on? Doesn''t the city have an explanation? " Another survivor''s attitude was obviously fierce, but still showed tension and worry.


    Of course, some people have long been dissatisfied with the management of the refuge, and take this opportunity to vent their emotions: "what are you doing? Don''t you care about the life and death of our common people? "


    Although it''s the end of the world, books still need to be read and homework still needs to be written. Teaching sites have been set up in various shelters, and daily teaching activities are still going on.


    But it also caused parents to worry: "how can there be no electricity! Children have to read and do their homework


    In the face of all kinds of problems, the managers of various shelters can only try their best to persuade each other with the help of the police, explain the current situation, and ask everyone to overcome the difficulties.


    Although most people feel very uneasy about this, since the explanation given by the municipal government is only temporary, they are willing to believe in the explanation given by the municipal government and overcome the difficulties for the time being.


    Of course, there are also people who want to make trouble or have ulterior motives, but these people are directly arrested by the police without exception.


    It was not imprisonment and imprisonment that were waiting for them, but rather hard labor.


    This is also the main means of punishment for criminals after the disaster. After all, there are no prisons for prisoners now. Instead of wasting food, they should be sent to work.


    Under such control, there was no trouble at all in the shelters. The survivors quietly accepted the current situation and believed that the crisis the city government said was temporary.


    ¡­¡­


    For the official shelters, this is only a temporary crisis or a temporary difficulty, but for the private shelters, the impact of this matter is light and heavy.


    Of course, the self-sufficient private shelters have no sense of the crisis, and they do not rely on the power and water supply of the city government. They are all on their own and naturally do not feel any impact.


    For example, the refuge of Chen Xin is a typical example.


    But for a shelter like Mo Qingyan, which relies on getting electricity and running water from the power supply lines of the official shelters, the city government restricts power supply, which is fatal.


    Mo Qingyan had a good life before, because she was able to get power from the power supply line of the official refuge to maintain the operation of her refuge. But now the official power supply is restricted, and the private refuge like her is obviously in danger.


    There''s not enough electricity, heating, lighting, maintaining the greenhouse Even for some people, it''s difficult to heat food.


    It is obvious that Mo Qingyan has been in crisis at this time.


    Although the ground source heat pump unit that Chen Xin installed for her ensures the heating and basic lighting power of her home, the power of her home''s ground source heat pump is limited, and the power generated is only the surplus after heating and maintaining the fish and vegetable symbiosis system. The power to maintain the lighting is barely enough, unable to drive other electrical equipment.


    ¡°¡­¡­ So now I can only live a hard life. If it wasn''t for the ingredients, you helped me install the ground source heat pump, I would have been frozen to death now. " Through the radio, Mo Qingyan explains her current situation to Chen Xin, and at the same time, she also tells him about her sufferings.


    "What are you going to do now? Can your family survive? " Listen to Mo Qingyan say her family problems, Chen Xin is also quite concerned about her situation.


    In the face of Chen Xin''s concern, Mo Qingyan''s tone is very helpless: "it''s not that I can''t support it. With the ground source heat pump you installed for me, heating is not a problem, and I''ve got the fish and vegetable symbiosis together. The ground source heat pump can maintain their operation, and there''s no need to worry about food. It''s just that there''s no electricity. Lighting and heating food are very difficult."If it is before the disaster, it is still able to use pipeline gas, but with the advent of the disaster, the pipeline gas that used to go into every household has obviously been unable to use.


    The self heating food stored before the disaster was also limited. Now more than half a year has passed, and Mo Qingyan''s self heating food is almost consumed. The rest is canned food that must be heated to eat.


    Although Chen Xin''s symbiosis system with fish and vegetables can provide her and her sister with vegetables and fish as food, it is obvious that these things can''t be eaten raw.


    Maybe vegetables can be eaten as salad, chopped and seasoned, but it''s not enough to eat vegetables.


    Hearing Mo Qingyan''s story, Chen Xin hesitated for a moment and then said to her, "how about long Niang, you move here for a while? The problems of the municipal government should only be temporary. It will be better after this period of time. "


    "To move to you? Ingredients where do you have a place for me and Xiaoxin to live? " Mo Qingyan obviously feels incredible about Chen Xin''s proposal. She has also been to Chen Xin''s home. Although all kinds of conditions are available, it is obviously not like she can live in two more people.


    "About this, I recently renovated my room. I came out with an extra bedroom, so that I could live more people. Besides, Alain and Xiaoding are here with me now." Chen Xin explains to Mo Qingyan and signals Qin LAN to help him persuade Mo Qingyan.


    Qin LAN is a little surprised by Chen Xin''s move, but she helps him explain to Mo Qingyan: "Qingyan, ah Xin can live two more people here now. You can move here. It doesn''t matter."


    Just so finish saying, Qin LAN then didn''t have good spirit of horizontal Chen Xin one eye.


    "Then let me think about it." Mo Qingyan didn''t make a decision right away. After a reply, she cut off the communication.


    After Mo Qingyan cut off the communication, Qin LAN pressed Chen Xin and asked, "ah Xin, I can understand that you asked Qing Yan and Qing Xin to move here, but where do you want them to live when they come?"


    "Let them live in my house, I sleep on the sofa, but just stay for a while, no problem." Chen Xinchong and Qin LAN smile. Obviously, they have already made arrangements for this.


    Let Mo Qingyan and Mo Qingxin stay for a few days and sleep in the two beds in his room. If he only sleeps on the sofa in the living room for a few days, it''s not hard to deal with the past.


    However, Qin LAN heard Chen Xin say so, but did not have the good spirit to hum a: "you knew the rotten good person! Do you sleep on the sofa by yourself and let Qing Yan and Qing Xin sleep on your bed? Do you think it''s appropriate? "


    "Well, this..." Facing Qin Lan''s interrogation, Chen Xin scratched his head and didn''t know what was wrong.


    Seeing Chen Xin''s attitude, Qin LAN can only look at him helplessly and says to him: "I move to your room to sleep. The empty bed is crowded by Qing Yan and Qing Xin, so it''s no problem."


    "Ah? Alan, you moved to my room? " Chen Xin is surprised by what Qin Lan said. Although this arrangement is the best for him, he still doesn''t understand why Qin LAN arranged it like this.


    "Ah, what! Only you and I can live in the same room, right Seeing that Chen Xin didn''t understand, Qin LAN could only explain to him: "it''s no problem that you ask Qing Yan and Qing Xin to move here, but you let them live in your room and you sleep on the sofa. What do you want Qing Yan to think? When she came to take refuge, she squeezed you out of bed? "


    Hear Qin LAN say so, Chen Xin also responds.


    Although he and Mo Qingyan are good brothers, it doesn''t matter if they sleep in one bed, but they really don''t let the guests sleep in the bed and the master sleep on the sofa.


    "That''s also true. Let''s do what Alain says." Chen Xin understands and agrees with Qin Lan''s arrangement.


    See Chen Xin agree, Qin LAN this just nodded, let him go back to the room, intend to move his luggage in the past.


    However, seeing Qin LAN carrying luggage, Ding Ning, who is resting in the room, is surprised and asks, "sister LAN, what are you doing? Finally, I can''t help but get back together with ah Xin? "


    Qin LAN heard Ding Ning say so, shook his head and said: "no, ah Xin asked Qing Yan and Qing Xin to move here for the time being, but something happened in the city. I moved to his room to sleep in the empty bed. It''s free for Qingyan and Qingxin. They can sleep in the same bed. "


    "Ah? I thought you finally figured it out, sister LAN, and wanted to get back together with ah Xin! " Ding Ning a face of regret, it seems that Qin LAN and Chen Xin do not take this opportunity to compound, it is a waste.


    For Ding Ning''s regret, Qin LAN just sighed helplessly: "I can''t get back together with him."

 Chapter 196

    The city government''s comprehensive restrictions on electricity use have had a serious impact on various shelters in the city, even the city government''s shelters themselves.


    In addition to the necessary electricity, all the extra electricity has been restricted and cancelled. Even the city government officials are only using emergency lights in meetings, instead of using electric lights as before.


    This is obviously a special experience for the officials, but at this time, no one will say anything superfluous, ask for special treatment, turn on the lights or anything.


    Although the restriction of electricity consumption has a certain impact on the daily work of the municipal government, it is not insurmountable. Using emergency lighting can still maintain the daily work.


    However, although the immediate difficulties can be overcome, it does not mean that the problem has been solved.


    The problem of coal shortage is still a major problem for the municipal government.


    The relevant situation has been reported to the provincial government, and the provincial government has been urgently allocating materials to support the city. The construction team of the railway department is also carrying out emergency repair of the railway bridge.


    But it will take time, and the situation is still not optimistic.


    So at present, the atmosphere in the city refuge is particularly tense, and all people are nervously dealing with the things at hand.


    Emotional comfort, material distribution, distribution and use of existing coal for survivors in various shelters


    All kinds of work made everyone busy. No one mentioned any vacation or off work. They were all busy and tired. They had a little rest and then went on to work.


    From the top officials to the bottom staff, there is no exception.


    The gate of the city government is still heavily guarded. Even because of the previous bomb attack and railway bridge explosion, the inspection is stricter. Not only do you have to check in, but also you have to check out.


    Secretary Li, as the Secretary of the city government office, does not enjoy any privileges. Even if he wants to leave the refuge for business, he also needs to go through a series of security procedures.


    "I''m sorry, Secretary Li. You need to check your bag, too." Of course, the staff in charge of the inspection knew Secretary Li, but he didn''t dare to say anything friendly or give him any preferential treatment at this time.


    Secretary Li didn''t mind. He just handed his briefcase to the other party and let the other party check it. At the same time, he was also being searched.


    There are some documents in the briefcase, and the staff did not take a close look at them. As long as they are sure that they are not dangerous goods or confidential documents, there are no strict restrictions on carrying other things.


    After the inspection, the staff returned the briefcase to Secretary Li: "sorry, Secretary Li, I''ve delayed you."


    "It''s OK. You need work, too." Secretary Li seemed to be very easy to speak. She took back her briefcase with a smile. Then she passed the checkpoint and left the shelter.


    Just looking at the figure of secretary Li leaving, the staff member murmured strangely to his colleagues: "what is secretary Li going to do? Why not take a bus? "


    "It''s no wonder that we don''t leave here by car." Colleagues nearby didn''t find this strange.


    If you go to other shelters by car, now that the underground passage has been basically opened, just take a car directly from the underground garage. There is really no need to go up to the ground and go out through the gate.


    After thinking about it, the staff member felt that there was nothing wrong with it, so he didn''t care about it, stopped the next person who wanted to go out and continued his inspection work.


    Secretary Li, who left the shelter, didn''t walk too far. He stepped on the snow for about a street. He looked around warily and saw that there was no one around. Then he pointed his flashlight at a nearby building that had not collapsed and flashed the light a few times.


    Soon there was also a flash of light in the building.


    When Secretary Li saw this, he looked around warily and made sure that no one was following him. Then he walked towards the building.


    Inside the building, in a closed room surrounded by walls, several people who can''t see clearly are waiting for Secretary Li.


    Seeing him coming in, the leader of them stood up and said hello to him: "uncle, you are here!"


    "AZU, what do you want to do! Why blow up the railway? " However, Secretary Li didn''t have any politeness to the people who said hello to him. He took off the protective mask on his face and asked him.


    "Second uncle, what do you mean?" The person who greets Secretary Li is still mild when he hears his question, but he doesn''t seem to understand what Secretary Li means.


    Secretary Li''s face was even more discontented, so he said angrily to him: "at the beginning, we agreed that I would send you a message, just to help you escape the capture of the city government, not to let you bomb the railway and bomb at the gate of the city government! Now you blow up the railway, the power supply and heating of the whole city will be affected! A lot of people will die! "


    "What does that matter? It''s just a necessary sacrifice. " This person seems to pay no attention to this, the expression on the face is still mild, but the eyes are not a trace of temperature, it is very cold."You call it necessary sacrifice? What do you think of human life? " Secretary Li looked at the person in front of him, as if he couldn''t believe it: "what do you want to do? Ah Zu


    "What I want to do is just to realize my ideal, so that everyone can get freedom and happiness. Zhengfu is just a shackle restricting freedom. Only by overthrowing the ruler can people get freedom! To be truly happy The face called AZU still has a mild expression and seems to have some smile, but his eyes turn from cold to fanatical, and he looks at Secretary Li sincerely in his tone: "this is my ideal! What I want to do! Second uncle, join us! As long as our plan is realized, the city will be managed by you, the second uncle, and you will be the mayor. Isn''t that what you always dream of


    "I want to be mayor, but not this one!" Secretary Li was shaken for a moment, but soon he shook his head and refused. He still asked AZU, "how many people are you going to kill for your freedom?"


    "Anyone who stands in the way of freedom is one." Perhaps Secretary Li''s refusal angered him, and the expression on AZU''s face became cold, and his reply was cruel.


    Secretary Li seemed to be shocked, stepped back a few steps, shook his head and said in disbelief: "AZU, how did you become like this? That''s human life


    "Sacrifice is always necessary for freedom." AZU didn''t seem to want to spend more time with Secretary Li. He said to him directly: "second uncle, you''d better think about it. If you join us, you''ll still be my good second uncle. When we occupy the city, second uncle, you''ll be the mayor of the city, and the city will be managed by second uncle.


    But if you are still so stubborn, I can only express my regret. Even if you are my second uncle, my only relative, I can only... "


    AZU said, took out the pistol from the body, but did not aim at Secretary Li, just from the exit of the magazine, and then took down a bullet, put into his coat pocket: "this bullet I keep for the second uncle you."


    Secretary Li looked at AZU''s action and understood what he meant.


    If Secretary Li is willing to join in and become an accomplice of AZU, he will use this bullet to kill a person and make a petition.


    But if Secretary Li is not willing to join, then that bullet is the one that sent Secretary Li on the road.


    With that, AZU took a look at his men: "send my second uncle out."


    Secretary Li seems to be scared by AZU. Although he wants to say something more, he can only be invited out by AZU''s men and leave stumbling.


    "Zuge, why are you so polite to him? Even without his help, we can''t do it." AZU''s subordinates don''t seem to understand what he''s doing. They ask AZU, but the subordinates don''t speak Chinese, but Vietnamese.


    "After all, he is my second uncle. After my parents died, my second uncle raised me. If it''s not necessary, I don''t want to fight him." AZU also answered his subordinates'' questions in Vietnamese, as if giving himself a reason not to kill Secretary Li: "besides, we are only mercenaries. We are good at fighting and killing, but managing cities Who knows? "


    AZU''s hands looked at each other, and he could not help shaking his head. These people let them kill and set fire. They are all good hands, but how to manage the city? They will only rob money and women, and those who make trouble will be killed.


    Seeing the appearance of his subordinates, AZU naturally knew that none of these people could be competent for the post of city manager. He shook his head helplessly and said, "so we need professional officials like my second uncle. Only he knows how to manage a city."


    "I see, Zug." AZU''s men nodded to show that they understood, but they asked new worries: "but brother Zuge, will he inform? Even if he is your second uncle, it doesn''t look like he will join us. "


    "Second uncle, he will not betray me, so he can''t escape." AZU seems to have a lot of trust in Secretary Li, but his next sentence shows that it''s not because of family affection: "and Lu will watch him. If he really wants to betray us, even my second uncle, I won''t be soft handed."


    Lu u is the only female under AZU''s command from Vietnam, and the only killer and intelligence officer in their whole team. So AZU put her next to his second uncle to protect Secretary Li and obtain intelligence on the one hand, and to monitor him on the other.


    After hearing what AZU said, AZU''s men looked at each other. It seemed that there was no problem, so one of them asked, "what are we going to do next?"

 Chapter 197

    "Here you are, sister." Mo Qingxin hands Mo Qingyan a can baked on the ground source heat pump hot water pipe. While opening her share, she asks Mo Qingyan, "sister, why don''t you want to move to ah Xin?"


    "Ah Xin doesn''t owe me anything. People have helped us so much. Do you want to stay with him?" Mo Qingyan looks at her sister and opens the can in her hand.


    Because the external power supply has been cut off, they can only rely on the electric energy from the ground source heat pump for lighting, and use the heat from the hot water pipe to heat the cans.


    Fortunately, these tins are cooked food. They only need to be heated, and they don''t need to be fully cooked.


    Eating cans, Mo Qingyan asked her sister, "Xiao Xin, how many cans are there at home?"


    "There are still seven cases of luncheon meat, four and a half cases of pork, and twelve cases of other canned food. It''s enough for the two of us to eat for more than half a year." Mo Qingxin had only counted the supplies before, so when Mo Qingyan asked her, she told them about their current supplies: "as for wine, there are still eight cases, plus your bottled collection. These things are enough for us to eat."


    Mo Qingyan heard that her sister said there was enough food, so she nodded clearly. She didn''t say much, but ate the can in silence.


    Mo Qingxin seems to feel that the atmosphere is a little dull, so she asks Mo Qingyan, "elder sister, why do you think the power failure of the municipal government is? Didn''t you have a good time before? No problem? This suddenly limits the use of electricity. Is there something wrong


    "There should be something wrong with the supply of coal." Even if she didn''t know what was going on, Mo could still guess: "now all the power supply in the urban area depends on coal-fired power plants. Now there is not enough power, it is only possible that there is something wrong with coal."


    "Ah? What can we do? Will it be like this in the future? " Mo Qingxin can''t help worrying.


    Although it has been more than half a year since the end of the world, and she has gradually become accustomed to today''s life, she has always lived with Mo Qingyan in the shelter of her own home, and the living conditions are not bad, and even there is not much sense of hardship after the end of the world.


    But now because of the power failure, the original electrical appliances in her shelter are basically unusable. She can only rely on the ground source heat pump installed by Chen Xin to maintain the heating and lighting. Her quality of life has dropped sharply.


    This undoubtedly makes Mo Qingxin feel quite uncomfortable.


    In fact, this is also one of the impacts of the comfortable conditions of private shelters. Because the preparations before the end of the world are sufficient, the private shelters can maintain a higher standard of living after the end of the world.


    Under such circumstances, people living in private shelters do not have the real sense of struggling to survive in the end.


    Because of adequate preparation, food, water and other materials, it can be said that as long as private shelters do not go out, they will not be very different from those before the end of the day.


    Of course, if the preparation is not enough, for example, like Mo Qingyan, there is no generator and well, and he relies on external power supply for water supply. Once the external power supply is cut off, it will be a huge blow to Mo Qingyan''s family as a private shelter.


    Their quality of life will decline rapidly, so that they can really feel the difficulty of survival at the end of the day.


    Of course, now that Mo Qingyan''s family has the ground source heat pump and fish vegetable Symbiosis System Chen Xin has sent her, the living conditions are not so bad.


    This whole set of equipment can provide heating, food and lighting, and even drinking water if you don''t mind. If you just keep two people alive, it''s no problem at all.


    It''s just that life has been very comfortable before. Mo Qingxin can''t adjust for a while. She still hopes to live a more comfortable life.


    "Let''s get used to it earlier. In the future Who can tell? Maybe it will get more and more sad. " Mo Qingyan shook her head and poured the last bit of juice from the tin into her mouth: "although it''s said that this time it''s a temporary power restriction, no one can tell what will happen in the future. In case of this situation in the future, Xiaoxin, you have to adapt to the harsh conditions."


    Hearing Mo Qingyan say so, Mo Qingxin can''t help but bow her head. Of course, she knows that she has to adapt to the current conditions of life, even worse living conditions and environment, but for a while and a half, she still can''t adjust.


    After dinner, because of the lack of electricity, the computers and game machines that the two sisters could play had been temporarily out of use, so the two sisters could only sit and chat around the little lighting provided by the fill light tube of the fish and vegetable symbiosis system.


    "Elder sister, what do you think is the cause of this blackout?" For this sudden power failure, Mo Qingxin is still very curious and wants to know what causes the power failure.


    Although we don''t know the specific situation, it''s not hard for Mo Qingyan to guess: "the power plant''s power rationing can only be caused by the damage of the generator set or the lack of coal. These things are controlled by the state. The plan must have been made before the disaster, so there was no problem for most of the past half a year. Now there is a sudden problem, either someone is doing damage, or where someone is Make trouble. ""Ah? How sick is it that you want to make trouble at such a time! " Mo Qingxin obviously didn''t think about this kind of thing. She really can''t understand why people still want to make trouble and sabotage in this eschatological environment: "even if they succeed, what good can they do? Not to mention the army''s encirclement and suppression, the country has taken a card of materials from outside, and everyone will starve to death! "


    For his sister can think of the topic, Mo Qingyan just shrugged, indifferent said: "if they can think of these, they will not make trouble.". And to be honest, for these people, they don''t need to consider the life and death of others at all. What they care about is whether their ulterior purpose can be realized.


    And don''t expect too much from the IQ of those people. When you were in the hospital, did you forget those people who came to see you with the information from online search? Last year, there were people in the Federation who believed that injection of disinfectant into their bodies could kill the virus. Do you expect those people to have brains


    "But, but This is in the state of Yan! Do you think that the army''s suppression is not fast enough to make trouble and sabotage in the state of Yan? " Mo Qingxin still thinks that she can''t understand. Even if some people have a bad brain or are blinded by lard, she can''t even see the gap in force, can she?


    For this problem, Mo Qingyan can''t help but show a sarcastic smile on her face: "when foodstuff used to write novels, she asked a LAN to help him find out how many people became emperors after the founding of the people''s Republic of China. How many people do you guess?"


    "No? Elder sister, do you mean after the founding of the people''s Republic of China? " Mo Qingxin''s face was shocked. She couldn''t imagine that after the founding of Yan state, there were still people who wanted to restore the monarchy.


    "Yes, after the founding of the people''s Republic of China, according to the records of a LAN''s files, from the founding of the people''s Republic to the present, there are at least dozens of people who call themselves emperors, from the early days of the founding of the people''s Republic to the 1990s." Looking at her sister''s face, Mo Qingyan said with a smile: "some of them are just ignorant peasants who want to be addicted to the emperor and incite a few relatives and friends to claim the title of emperor. Some of them really encourage hundreds of people to make trouble in the county and cause the army to suppress them. Some of them have been solved because of traffic congestion for more than ten years


    In general, there are more than a dozen detailed information circulating on the Internet. The most recent one was even last year when he claimed to establish a federation or elect himself as a commander in chief in a foreign hotel This man, once he has ambition, his brain will not work well. "


    Mo Qingyan is telling a joke, but Mo Qingxin feels that her three views have been subverted.


    Now it''s more than 70 years since the founding of Yan state. The last emperor has been dead for more than half a century. How could anyone want to restore the monarchy?


    It''s hard to imagine what these people are thinking.


    However, since there are such people, there are people who want to take advantage of the end of the world to engage in sabotage or make trouble, it''s not surprising.


    And to tell you the truth, in today''s state of inconvenient transportation, if the railway is broken, it is equivalent to blocking the traffic. Although it blocks the input of external materials, it also blocks the connection between the city and the outside world.


    In the case of excluding the influence of external factors, if only a small place like a county to make trouble or engage in destruction, the probability of success is not small.


    Thinking of this, Mo Qingxin can''t help but agree with her sister''s judgment. She thinks that this time, someone is really doing damage.


    The two sisters did not continue to talk about this topic, and for a moment, it was a little dull.


    Mo Qingyan stood up and washed the empty cans that the two sisters had eaten with water. Then she put them aside. These cans are all made of metal. They are very useful things in this end of life. It''s a good choice to pack things or use them to do something.


    It''s just that Mo Qingyan doesn''t have Chen Xin''s hands-on ability and system support, and she can make all kinds of things, so for her, these tins can only be used as materials. Maybe she will exchange them for other things.


    Just as Mo Qingyan was thinking about what these tins could be used for, Mo Qingxin on one side suddenly opened her mouth and asked her, "sister, if your parents are still here, what will they say when they see us like this?"


    "Dad must be concerned about how we eat and how we live..." Hearing her sister mention her parents, Mo Qingyan''s face changed: "as for mom I''m afraid we still don''t think we''re married yet? "

 Chapter 198

    The blackout in the urban area has caused quite a huge impact, but the culprits who created everything have not been affected.


    Although AZU had met with his staff and Secretary Li in the city before, in fact, the stronghold he and his people occupied has been outside the city.


    The stronghold controlled by AZU is quite far away from the urban area. Although it is in the same area as Chen Xin''s refuge, it is far away from the urban area. It is just a small village level refuge.


    Although these shelters were built three months before the disaster, considering that the population of the villages and towns was not large and the construction quantity of these shelters was not particularly large, the government of the state of Yan built many such small shelters in villages and towns at all levels at that time.


    The area of this kind of refuge is not large, and the construction depth is not deep. Most of them just dig a large pit more than ten meters deep on the ground, and then build a small bunker that can accommodate about a few hundred people in the pit, and then backfill the excavated soil to form a soil layer about 20 meters thick.


    Although the construction is relatively simple, it is enough for three or five hundred people to take refuge in a short time.


    After all, it is only used to resist the fire, low temperature and other possible secondary disasters brought by the doomsday natural disasters, not to resist the military attacks such as nuclear bomb or conventional missile attacks. It does not need to reach the defense level of civil air defense fortifications.


    However, all the advantages and disadvantages of this kind of small refuge are natural. Because the place is small, it is impossible to have a special greenhouse and supporting living facilities like the large refuge. Coupled with the area, the living environment of the survivors in the small refuge is hardly comfortable.


    This refuge is not a refuge occupied by AZU and his subordinates, but a refuge in the village where their original family and relatives lived.


    Of course, AZU didn''t come out of thin air, and they were not crazy people with bad brains.


    AZU and his closest brothers are all from the city, but they were brave and fierce when they were young. In the local dialect, they were called Cao Zi, who did not study well and did not mix in the street.


    AZU''s parents died when he was a child. Although he was raised by his second uncle, he was already a civil servant of the municipal government at that time. He didn''t have much time to manage him, so he became a street thug.


    However, Secretary Li already had a certain position and relationship at that time, so he was sent to serve as a soldier for the sake of AZU.


    But even if he entered the army, some of AZU''s bad habits have been formed. After two years of being a soldier, he still idles and has no serious work.


    Secretary Li couldn''t bear to see him degenerate like this, so he went to his friend who was doing business in Yunnan Province and introduced AZU to him, hoping that AZU could learn some skills from his friends.


    So AZU followed Secretary Li''s friend to Yunnan Province.


    As for how AZU became a mercenary, and how he became famous in Southeast Asia with a group of brothers, we can only say that everyone has his own fortune.


    Originally, AZU and a group of brothers were pretty good in Southeast Asia. They helped local warlords fight and train their troops. They lived a smart life. Even the regular troops of several local countries were not paid attention to.


    Although they can''t fight, they can''t help it.


    This kind of life, although there is no future, but there is nothing bad. After all, they are mercenaries. They may die one day, and they don''t think much about the future.


    But by chance, AZU came into contact with a doomsday sect.


    The core tenet of this sect is not complicated. What it preaches is freedom and happiness. At first glance, there is no problem, but their interpretation of freedom is very perverse.


    According to the doctrine of this sect, real freedom can not be bound by anything. All morality, legal system and rulers are just the shackles of oppression and restraint of freedom. Only when the end comes and all these constraints are broken, can real freedom be won.


    In the eyes of any normal person, this kind of words is pure fart, and there is no so-called absolute freedom in this world, because people will always be affected and restricted by other factors in this world, and it is impossible to completely do what they want.


    And you do what you want. What about the others?


    Take the simplest example. If you want to roll on the street at will, and others want to drag on the street at will, if there are no rules, it must be someone else driving over your head.


    Therefore, the existence of rules and constraints is necessary, and the ultimate result of unrestricted freedom can only be destruction.


    But this kind of bullshit is very popular with the lawless people like mercenaries, even in their hearts.


    So AZU and his brothers believed in this doomsday sect and became more and more lawless. Even the regular armies of Southeast Asian countries were more and more ignored.


    At first, it''s OK for everything to go on like this. Either AZU was killed by the regular army on the battlefield one day, or they made enough money to retire, or they were bewitched by the doomsday sect and became cult members.However, the arrival of meteorites has disrupted all this. Under the threat of doomsday natural disasters, no country in Southeast Asia can control the situation, and everything is in a mess.


    Under the collapse of order, this should have been the era of freedom advocated by the doomsday sect, but that sect was just a tool for the high-level of the sect to collect money under such a banner. Under this real doomsday natural disaster, the high-level of the sect itself collapsed.


    AZU was obviously disappointed by this situation. After killing all the collapsed high-level sects, what to do made them confused.


    Finally, an old brother proposed to go back to his hometown. AZU found their goal and direction. A group of people made use of the money they had accumulated for many years and some relationships and contacts to enter the state of Yan through the border of Yunnan Province. After several rounds, they returned to their hometown in Hunan Province.


    because the group of Zu Zu has registered residence in the country of Yan, they are not mercenaries in Southeast Asia and have no real identity with them. So they are just a group of normal people who come back from Southeast Asia. What''s more, there is no identity problem.


    In addition, they entered the country through regular channels and did not carry dangerous goods, so their entry did not cause any trouble and waves.


    Back in his hometown of Hunan Province, even the lawless mercenaries were much more honest before the end of the natural disaster. They didn''t cause any trouble and disturbance, and they entered the small refuge in their hometown very smoothly.


    As I have said before, the living conditions of these small shelters are far from good. At first, they were able to endure the threat of natural disasters. However, with the stability of the external environment and the bad living environment, some ideas in the minds of these mercenaries began to breed.


    With the help of the methods learned from the doomsday sect, AZU and his followers began to spread the teachings of that doomsday sect in the small shelters. With the help of their relatives, they soon turned hundreds of people in the shelters into believers, and spread their faith to several small shelters at the nearby village level.


    For this group of mercenaries who have been living in Southeast Asia for a long time, the end of chaos is simply the best environment for them. In addition to the teachings of the doomsday sect, they easily obtained a large number of loyal believers, among whom the elite were strictly trained and controlled by their spirit, and became the elite "cannon fodder" who were not afraid of death.


    This is also the reason why they are able to use suicide attacks when they attack No. 2 refuge and municipal refuge in Baling County, because they have "dead men".


    However, it''s not easy to cultivate these "dead men". If it wasn''t for the purpose of realizing his plan, AZU would not have consumed his own staff.


    Now that his basic purpose has been achieved, it''s time to consider the next step.


    "Old four, what''s the situation with the shelter you were staring at before?" AZU looked at one of his brothers and asked him.


    The so-called old four is a special intelligence and surveillance officer in their mercenary team. Hearing that AZU asked about the shelter, he replied: "basically, it''s the same as before. There''s nothing moving. As mentioned before, two policewomen have lived in it, and they haven''t been out of the house during this period.


    Only two days ago, when we started, a group of people came. Later, they drove a car out. The car has been transformed and can run normally in the snow. This technology is very useful and we should master it. "


    After listening to the fourth report, AZU couldn''t help picking his eyebrows: "a car that can run normally in the snow? It seems that the people living in that shelter are unusual! We need this person in our career. "


    As mercenaries, even if they don''t know the technical content of normal driving in snow, they also know what mobility means in military operations.


    "But that shelter is not easy to fight. I''ve seen his gate. Even if there are rockets, it''s hard to fight in. As long as the other side doesn''t open the door, we can''t do anything about it." Fourth, of course, knows the meaning of the shelter they are talking about, but the problem is that it''s really a hard bone to chew. He seems to be afraid that AZU doesn''t understand. He added: "we''ve been observing that shelter for several months, where a cart of vegetables can be produced every month, which is enough to prove that the other party doesn''t have to worry about food and drink. In the case of not breaking the door, the other party can afford it, and we can''t afford it I''m sorry


    "So we have to make a quick decision, attack quickly when the other party opens the door or goes out, and control the people in the shelter." Of course, AZU understood Lao Si''s meaning, but he didn''t care. He was just an ordinary man and two policewomen. Even if he had a gun, how could he do it with his brother and a group of trained dead men?

 Chapter 199

    Chen Xin naturally knows nothing about AZU and others'' intention to seize his refuge or even control him. Even Chen Xin does not know that his refuge has been monitored.


    But even if he knows, I''m afraid in Chen Xin''s opinion, it''s not something that deserves his attention.


    Even the modern army has to rely on heavy firepower to blow the door open because of the firmness of the 300 mm thick nichrome armored steel gate at the main entrance of the refuge.


    This kind of heavy firepower does not mean heavy machine guns or rocket launchers, or even mortars. It means real heavy firepower, at least the armor piercing projectiles from the main guns of the main battle tanks.


    Don''t think this is an exaggeration. During World War II, the front armor thickness of the main turret of Bismarck class battleship was 360mm, that of hood Battlecruiser was 381mm, and that of Missouri battleship was 495mm


    It can be said that Chen Xin''s gate was the battleship class defense during World War II. During World War II, the main turret armor of battleships was the thickest part of the whole warship. Only the main guns of other battleships could penetrate it.


    Even with the development of modern military science and technology, the armor piercing ability of artillery has been greatly improved. It is not possible for ordinary caliber artillery to penetrate 300 mm homogeneous Ni Cr alloy armor steel.


    Moreover, this kind of large caliber heavy artillery, even in a big military country such as the blue star five, is also used to equip the first-line main combat forces, not to mention the special police or the armed police, even the general second-line forces may not have such heavy firepower.


    Therefore, several terrorists are really ignored by Chen Xin.


    Even if they can launch a man bomb attack and let the fearless cannon fodder be bound with explosives to blow up the door, the two double mounted markchin in front of Chen Xin''s door are not for display.


    Although not many bullets were prepared, there was no problem in killing three or five hundred people with the help of automatic aiming.


    It''s not nice to say that with the current defensive ability of Chen Xin''s shelter, even if the special police and the armed police in the urban area attack together, there is no possibility of fighting down.


    Perhaps the biggest result they can achieve is to leave a few bullet marks on the gate of Chen Xin''s refuge with heavy machine guns.


    With this kind of defense, Chen Xinli certainly won''t worry about his own safety problems, so he has time to transform his car.


    After Li Yulong sent the car parts and other related materials, Chen Xin''s car transformation plan also went smoothly.


    Today''s car is no longer the SUV it used to be, or even two cars.


    If it wasn''t for the information state concept fuzzy technology provided by the system, I''m afraid no one would think that this car comparable to a large bus is transformed from an SUV, and there is no similarity between the two.


    Under the 12 meter long vehicle body is a segmented crawler chassis. Under the front double row three defense cockpit is a four meter long crawler. Under the rear life cabin is a six meter long crawler.


    Chen Xin originally intended to build a whole track, but after the upgrade, it became such a segmented type. He can only default. After all, he is not a professional, and he can''t tell which one is better than the other.


    The whole car uses 9mm thick steel plate as the skin, and the main parts are equipped with armor plates. The chassis can resist the attack of mines or grenades. Even the front cockpit glass can only be penetrated by large caliber anti equipment sniper rifles.


    The surface is painted with snow camouflage. In this dark snow environment, this is the best camouflage. In addition, the car uses the triple 200 kW isotope thermoelectric battery as the power source for electric drive, which makes the car extremely difficult to be found.


    The infrared night vision device attached to the cockpit allows the car to drive without driving the lights, which effectively eliminates the possibility of the car being found.


    In addition to these, the car is equipped with a radar that Chen Xin doesn''t know about, which can easily detect all moving objects within a radius of 5 km; and four military UAVs, two of which are equipped with machine guns as weapons.


    There is also a hidden 12.7mm caliber three barrel Gatling machine gun on the roof, equipped with high explosive combustion armour piercing ammunition. Except for the main battle tank, there is no land vehicle that can withstand this degree of fire.


    As for the interior of the car, the living cabin is equipped with a luxury saloon car. It is equipped with a fully functional flow table, an induction cooker, a microwave oven, a sink, a washing machine, a dishwasher, and a cabinet that can store a large number of kitchenware.


    In addition to the bathtub, the dry wet separation toilet on the car is no different from the ordinary household toilet.


    After careful design of two 2.1m ¡Á 1.8m double beds and two 0.8m ¡Á 1.8 single beds, you can sleep at least six adults without pressure. Even if you squeeze it, there is no personal problem.


    The car has a complete water circulation system, with a water tank that can hold five tons of water and a water treatment and filtration system, which is enough to provide sufficient domestic water for six to eight passengers on board.Even in order to ensure that the car can meet the needs of long-term survival in the wild, Chen Xin also installed a planting box with five layers of 0.2m ¡Á 0.6m, which can provide sufficient vegetables, with a large trunk at the rear of the car, and can hold enough food for six people for a month without pressure.


    With this car, Chen Xin has enough confidence to be able to return to his hometown and pick up his parents.


    He believes that with this car, he can cope with the journey of more than 600 kilometers across four provinces and successfully pick up his parents.


    Of course, such a luxury configuration, excellent performance of armored RV up the cost of transformation is extremely amazing.


    If Chen Xin hadn''t gathered a lot of raw materials through Li Yulong, and transformed and processed a large batch of spare parts by himself, the survival points needed to upgrade such a car would be enough to upgrade a half refuge as a whole.


    Even with sufficient materials, the 2500 point survival still makes Chen Xin feel extremely painful.


    But he bit his teeth and put the survival into it.


    After all, it''s a car to pick up his parents. Now he''s afraid that there are some shortcomings or loopholes in the car, which will not make him return to his hometown smoothly.


    In addition, no matter how much resources and survival are consumed, Chen Xin will give up.


    Now that such a car has been upgraded successfully, Chen Xin also feels that it is worth the money.


    "It''s over at last! Ah Xin, your hands-on ability is too strong! " Ding Ning looked at the armored caravan in front of him, and was amazed.


    In her and Qin Lan''s eyes, the car was transformed bit by bit by both of them with Chen Xin, so it''s hard to be excited to see the upgraded armored RV, no matter Ding Ning or Qin LAN.


    However, in Chen Xin''s opinion, it''s a bit of a violation. In order to avoid exposing his biggest secret, Chen Xin said to Ding Ning and Qin LAN, "thank you for your help. If I want to complete the transformation of this car alone, I don''t know how busy I will be."


    "Ah Xin, you''re welcome. Ah Ning and I didn''t do anything. We just gave you a hand. It''s nothing." Qin LAN shook her head. Although she and Ding Ning did help a lot in her perspective, her personality did not make her feel that she had done much.


    Chen Xin didn''t like it either. He opened the door on one side of the car, put down the gangway and said to them, "two beauties, do you want to go up and have a look together?"


    In the face of Chen Xin''s invitation and the powerful but restrained heavy armored RV in front of them, Qin LAN and Ding Ning look at each other and can''t help laughing at each other. They board the car together.


    Because it''s a car from the middle of the car body, so after getting on the car, what appears in front of them is a table and a circle of zigzag sofa around the table.


    Chen Xin also got on the bus at this time and said to them, "this is the living area. You can sit here to eat or chat. The front is the cab, and the back is the bedroom, kitchen and bathroom."


    As he said this, Chen Xin lowered the table in the middle of the sofa and explained to them with a smile: "this table can be lifted and lowered. After it is lowered, there is a double bed."


    "Double bed?" Ding Ning looked at the table that had fallen to the level of the sofa beside him, and couldn''t help saying to Chen Xin: "it looks very spacious. Is it comfortable to sleep at night?"


    "I don''t know. I have to go to sleep and try." For this problem, Chen Xin can only smile that he does not know.


    Compared with Ding Ning, Qin LAN is more concerned about the living area. She takes the initiative to go forward and enters the cab after passing through a passage less than half a meter long.


    Chen Xin naturally follows. Seeing Qin LAN looking at all kinds of equipment around the driver''s seat curiously, he takes the initiative to introduce them to her one by one.


    Listening to Chen Xin''s introduction of the radar, UAV and night vision equipment, Qin LAN could not help sighing: "ah Xin, you are better than the armored vehicles used in our team."


    "No way! After all, I have to go through six provinces and run more than 600 kilometers to meet my parents. If the function of the car is not complete, I can''t run so far to come back. " Chen Xin can only say that this is a practical need.


    However, after hearing Chen Xin''s words, Qin LAN just looked at him and asked him a question: "ah Xin, when are you going to leave and go back to your hometown to meet your parents?"

 Chapter 200

    It''s the most urgent thing for Chen Xin to go back to his hometown to meet his parents.


    Originally, there was no proper means of transportation, which was the biggest obstacle for him to do it. But now that the car has been transformed, this matter has been put on the agenda, and has become what Chen Xin is about to do.


    But no matter how urgent his mood is, it is still not a walk on the road.


    Although he has the means of transportation, he has a long way to go. He must have enough water and food and other related materials. After all, he doesn''t know what''s going on with his parents.


    Before the disaster, Chen Xin finally received the news that his parents and relatives had entered the village''s shelters.


    All the people in that village are relatives of their families. Since the construction of the shelter, Chen Xin has been giving them advice on various precautions and the construction of survival facilities. What Chen Xin has prepared for himself, he has told them to prepare.


    Therefore, the living conditions of that mountain village shelter are not bad, and there is almost no big difference between it and the shelter before Chen Xin upgraded the system. Even because the area is large enough, it may be more comfortable to live in.


    So Chen Xin doesn''t worry about the danger or trouble his parents and relatives will encounter. The village is more than ten miles away from the nearest town, and it takes an hour to drive from the county. No one will be interested in such a remote mountain village.


    However, although it is said that, what will happen is something that no one can predict. The closed environment in the mountain not only avoids external interference, but also brings great inconvenience to the contact between the mountain village shelter and the outside world.


    After all, the village in the nearest town has more than ten miles of road, and the mountain road itself is not easy to walk. It is not easy to enter the mountain under the condition of heavy snow, and it is also very difficult for mountain people to get out.


    If something happens in the mountains, it is very difficult to come out for help or go in for help.


    Although Chen Xin doesn''t think there will be a big accident at the mountain village refuge, he has no guarantee that there will be no accident there.


    In order to cope with the possible situation, Chen Xin must be well prepared to set out.


    No one knows what will happen along the 600 kilometer road. It is hard to say whether there will be a refuge on the road. Chen Xin must prepare for the worst.


    More than 600 kilometers of journey refers to the highway before the disaster. In the past, the service area was used to provide rest and supplies along the way, but in this case, it is very likely that there will be no refuge along the way, unless Chen Xin specially enters the city.


    If he can''t supply all the way or meets a shelter, he should at least have enough supplies on board.


    Thinking of materials, Chen Xin can''t help but ask Qin LAN: "a LAN, there are so many things happening in the urban area, can the special police team come to exchange materials this month?"


    "It should be possible. Although there have been a lot of things recently, the exchange of goods and materials itself should not be affected, that is, the goods and materials used for exchange may be less than satisfactory." Qin Lan thought for a while, think this matter should have no hindrance, can carry on the material exchange normally.


    Chen Xin nodded to show his understanding, but after thinking about it, he said to Qin LAN, "then you can contact uncle Ding for me and tell him that I will use the materials for the next two months as collateral to advance some materials with him. If I want to meet my parents back home, I need to prepare sufficient materials."


    "It''s going to be a bit difficult, I''m afraid." Hearing Chen Xin''s request, Qin LAN frowned: "although the exchange of goods and materials can be carried out as usual, now all the staff of the special police team should be devoted to dealing with the recent attack, and there is no spare energy to collect goods and materials.


    Ah Xin, there should be no problem if you want to exchange food and other materials, but other materials are enough. I can only try my best to help you tell the team leader that I can''t guarantee what can be exchanged. "


    "OK, I know the situation of the special police force. I''ll make a list for you later. It''s mainly about building materials and steel. I''ll change what I have." Chen Xin knows the current situation of the special police team, so he also understands what Qin Lan said.


    But before he set out to pick up his parents, he planned to upgrade the shelter as a whole. In addition, he had to prepare materials for going out. Materials and materials are indispensable.


    "Well, you can give me the list later and I''ll ask the captain." Qin LAN nodded and agreed.


    Because the car has been transformed, Chen Xin will start to load all kinds of materials into it in the next time.


    Of course, water and food are the first things to be loaded into the car.


    For Chen Xin, there is no shortage of food. Up to now, there is a lot of food in his storeroom. Even if he eats it alone, he can eat it for half a year.


    He took two boxes of unopened shelter food from the storeroom and put them on the car. Chen Xin estimated that the journey was more than 600 kilometers, which should be between 1300 and 1400 kilometers.If there is something wrong with the road and you need to make a detour, you may have to run 1500 kilometers.


    Chen''s new conservative calculation is that it will take about a month to run the whole distance according to 50 kilometers a day.


    Two boxes of shelter food can be regarded as the basic rations for him during this month''s journey. If there is no supplies on the way, these foods can be regarded as his minimum rations.


    In addition to the two boxes of shelter food, Chen Xin also planted lettuce in the planting box on the car and brought a bag of seeds.


    These lettuce are not only rations, but also can be used to exchange food supplies with Refuges or supply points on the road when necessary. Although there may be no supply points on the way, they pass through four provinces and several cities. If necessary, they can also go to refuges in these cities.


    Of course, these are just supplies for emergencies. What Chen Xin really plans to eat on the road is a box of canned luncheon meat and a box of self heating food.


    In addition, he plans to prepare 100 Jin of dehydrated vegetables and 100 Jin of rice for himself. He also plans to prepare two boxes of shelter food after the material exchange is completed this month. In this way, even if he receives his parents, Chen Xin will have enough food on his way back.


    As for the domestic water on the road, Chen Xin doesn''t worry about it at all. After all, there is a water tank with a capacity of five tons. So much water is enough as long as it is not wasted.


    After all, when Chen Xin was alone, he used three tons of water a month. In addition, he also prepared a purification filter in his car. When he couldn''t, the snow on the roadside could be used as a source of water.


    Chen Xin connected a water pipe for flushing from the decontamination room next to the garage. While filling the water tank, he was still thinking about what he had not prepared.


    He doesn''t need gasoline. There are three isotope thermoelectric batteries in this car. One is used to power the engine, the other is used to power the compartment, and the other is used for standby or connected to the engine when necessary to overload the engine.


    Each isotope thermoelectric battery has a service life of more than 10 years, with a rated output power of 200kW. Along the way, you don''t have to worry about "running out of oil".


    The trunk is full of food. One hundred jin of rice and one hundred jin of dehydrated vegetables, together with a box of self heating food and a box of canned food, are the main food on the road. Four boxes of shelter food are emergency reserves. Even if there is any accident, they should be enough to eat.


    The water is being added by itself. The outlet of the water tank is connected with a purification filter. If necessary, you can shovel snow directly from the roadside and throw it into the water tank for water replenishment. You are not afraid that the water tank may be polluted.


    Other things that need to be prepared


    Just as Chen Xin was calculating what else he needed to prepare, Qin LAN, who had contacted with the special police team, came to him and said, "I''ve already talked to the team leader about the exchange of goods and materials. The team leader said that there''s no problem with what you want, and you can promise to advance the next two months'' transaction of goods and materials, but the team leader said that there is a prerequisite for all this ¡£¡±


    "Preconditions? What are the conditions? " Chen Xin looks at Qin LAN and says that uncle Ding is willing to exchange materials only if he has preconditions, which doesn''t surprise him or make him unacceptable.


    "The city government plans to open a previously closed small shelter. It wants to use the ground source heat pump technology you provided to the team as the heating and power generation facilities of this small shelter." Qin LAN looked at Chen Xin with a calm look, and then explained to him: "that small shelter is about the same size as the one allocated to Li Yulong by the municipal government, so the team leader asked me to ask you, how many ground source heat pumps are needed to meet the heating and power needs of such a shelter, how long can you deliver the goods, and what materials do you need."


    After listening to Qin Lan''s introduction, Chen Xin picks his eyebrows and feels a little surprised. However, he feels that this is reasonable: "is the municipal government planning to adopt a new model?"


    "It may be due to the shortage of coal, so I want to share the risk." Qin LAN did not know the reason why the municipal government did this, but there was nothing strange about it: "Xin, can you solve this problem?"


    "It''s not hard to meet the heating needs of a small shelter. As for electricity..." Chen Xin touched his chin and thought about it for a while. He said, "if you don''t think about planting greenhouses like Bruce Lee, 50 sets of ground source heat pumps should be able to meet the needs of heating and basic lighting. However, this figure is only my estimate, and I can''t guarantee that it will be enough. It may take two weeks to deliver the goods, and the materials are the same as the last transaction."

 Chapter 201

    The city government wants to install ground source heat pump in small shelters, which in Chen Xin''s view should only be an attempt for large-scale application of ground source heat pump.


    This time, because of the shortage of coal in the urban area caused by the explosion of the railway, the shortage of electricity in the urban area and the possible heating crisis have sounded the alarm for the municipal government.


    Of course, all kinds of emergency plans had been made before the disaster. For example, in this case, the municipal government relied on the emergency coal reserves in advance to support for several days, waiting for the provincial government to allocate coal from other places, and solving the problem of coal shortage.


    But all of this is clearly not foolproof.


    This time, only the railway was destroyed, which delayed the railway transportation for about a week. As long as we get through the railway, we can solve the problem. But what if this crisis can not be solved in a week, and the provincial government can not allocate coal from other places in time, or the railway that allocates coal into the city is blocked?


    The city government must consider the possibility of various accidents, and at this time the group of ground source heat pumps in the special police team naturally became one of the choices that the city government considered.


    This batch of ground source heat pumps have been put into operation for a long time, and their survival points have been settled. At that time, they brought a total of 5000 survival points and daily income of survival points + 50 points to Chen Xin, which made Chen Xin know that a refuge under the current scientific and technological level can only obtain so many survival points on an improvement item, and put an end to his idea of large-scale brush survival points.


    Of course, even so, 5000 points of survival and daily income + 50 points are still a very rich income for Chen Xin.


    It is precisely because of this income that Chen Xin dares to transform his bedroom and upgrade his car.


    Now the municipal government proposes to use ground source heat pump for heating and power generation in a small shelter, which is a good chance for Chen Xin to earn a lot of survival.


    Although he still has thousands of survival points on hand, and his daily survival income exceeds 100 points, as an important resource for using the system, no matter how many survival points Chen Xin has, he will not have too many.


    It''s just that Chen Xin is going to pick up his parents now. He has no time to rub the ground source heat pump slowly in the shelter.


    However, the city government obviously didn''t mean to push forward the project after he went to get his parents back. Can we get the parents back with the help of the city government?


    Through the city government to pick up the parents in their hometown instead of themselves, this kind of thing is also under Chen Xin''s consideration and plan.


    However, he consulted Qin LAN and asked Uncle Ding about it. The current railway transportation network is not open to civil or passenger transportation, and there is no demand for it.


    In addition to material transportation, only in case of emergency can railway trains carry people, and there is no special train, only in the rear of the material transportation car with carriage.


    At ordinary times, officials need to go to other cities. They also need to issue various certificates to explain the reasons, and then they can get a free ride on the material transportation train.


    For example, in this attack on the city government, people from the provincial government came to the city from the star city only through an emergency car and a material transport vehicle hanging on the back of the north.


    Chen Xin hopes to take over his parents by railway through the relationship between the city government, which is almost impossible.


    It may be possible to adjust the relationship within the province by relying on the municipal government, but Chen Xin has to go through four provinces along the way, which is obviously far beyond the jurisdiction of the municipal government. Even the provincial government may not be able to clear the barrier along the way.


    After all, it''s too far to cross four provinces, and there are too many hurdles on the way.


    What''s more, even if the municipal government has the ability to get through this barrier and help Chen Xin take over his parents, why do they have to sell Chen Xin''s face and help him?


    Therefore, taking the train to pick up people is naturally excluded from Chen Xin''s choice. He can only pick up people by himself.


    But now the municipal government has proposed to pilot ground source heat pump equipment in small shelters, and Chen Xin obviously does not want to give up this matter.


    Although it''s just a small shelter for the pilot, since it''s a pilot, it''s natural to think that it will be promoted after it''s good. In addition, Chen Xin''s departure is not a one-off affair, and he will come back in a month or two at most. He should not refuse it.


    But this conflicts with his going to pick up his parents. How should he deal with this?


    Of course, it''s OK to postpone his departure time and make a batch of ground source heat pumps for the municipal government for two weeks. However, in order to avoid long dreams, Chen Xin still hopes to start as soon as possible and doesn''t want to delay two weeks.


    To complete this order in a short time, and then reach a deal with the municipal government, you can set out to pick up your parents according to the original plan. Of course, this is the most ideal choice and solution.


    However, there is no system drawing for ground source heat pumps. Even if Chen Xin can use the workbench to process parts conveniently, he can produce at most two or three ground source heat pumps a day. The number of 50 ground source heat pumps he reported to the municipal government will take two weeks in any case.


    In front of Chen Xin, it seems that the only choice is to upgrade the workbench and improve the efficiency of the workbench in manufacturing ground source heat pump.Fortunately, this choice is not unacceptable to Chen Xin.


    "AZU, I''ve received a message from Lu that the city government will have a batch of supplies to the shelter in two days." Laosi found AZU and told him the latest news: "this is a great opportunity to take the shelter!"


    "Are you sure?" AZU was not as excited as old four, but confirmed to him.


    "It''s from Luu. It won''t be a problem." The fourth obviously believes in Lu''s ability and does not doubt the accuracy of the intelligence.


    AZU also nodded when he heard that, but he obviously thought more about it: "by what means did the other party contact the municipal government? How does the city government send materials to him? Are you clear about these questions? "


    "Luu has already inquired about it. The shelter communicates with the city government on a short wave radio station, and there will be a lorry to deliver goods and materials at that time." Lu didn''t leave out these details, and Lao Si naturally told AZU.


    After hearing Lao Si''s explanation, AZU thought about it seriously and said to Lao Si, "prepare two plans. Go and get a truck to disguise as a material delivery vehicle, cheat the gate of the shelter, rush in and control the people inside.


    If the scheme fails, wait for the people of the city government to send them materials. When he opens the door, he organizes people to rush to seize the refuge.


    It''s very important for the people in the shelter who can transform the car and let the car run on the snow. Try to control him and let him join us, so we can not kill people and try not to kill people. "


    "I know, AZU, that''s the best way to do this kind of thing!" Old four is good at intelligence, not at this kind of camouflage attack, but some of AZU''s brothers will do this kind of thing.


    Although the camouflage level is not high, but the operation in the old four do not seem to use too high level of camouflage.


    AZU naturally knew the strengths of his brothers, so he nodded and said, "I believe in the ability of old three, but for the sake of safety, you let old six go with him. Old six is more clever. In case of any emergency, he can deal with it better than old three."


    "I see. I''ll go to the third and sixth." Old four nodded.


    "ah Xin, why do you want to rebuild the shelter? Isn''t it nice for you to live in this shelter now? " Qin LAN helped Chen Xin and the municipal government confirm the ground source heat pump, but he was puzzled why Chen Xin had to change so many materials to transform his refuge.


    Although the concept of information state provided by the system is vague, Qin LAN can automatically rationalize the cognition of Chen Xin''s upgrading of the refuge, and thinks that he is only carrying out the transformation, but the motivation of the transformation itself cannot be rationalized, which still needs Chen Xin''s own explanation.


    "I''m going to pick up my parents and make the place more comfortable, right? It''s a bit cramped for me to live alone in such a big place. Plus my parents, it''s necessary to expand it. " The system has helped him turn the most unreasonable places into compound logic, and it is certainly not difficult for a former Internet writer to make up a reasonable reason and excuse.


    Qin LAN heard Chen Xin say so, but he nodded understandably, and then turned to ask: "so you want to complete the transformation before you start?"


    "Well, I''ll finish the renovation of the shelter and the GSHP order from the city government before I go to pick up my parents." Chen Xin nodded and affirmed Qin Lan''s question: "it may take a month or two to run this trip. I can feel more at ease if I start after the transformation of the shelter."


    One question has been answered, but Qin LAN has another question: "Xin, I can understand what you say, but once you go for a month or two, what do you know from the captain about the materials for the next two months? If you are not here, who will take care of it? "


    "Let the dragon lady take care of it for me. She didn''t want to let her sisters live here before. Maybe she was afraid of being in debt to me. Now let her help me take care of the land outside my home. If I owe her, it should be OK." Chen Xin has long planned to solve this problem. He explains his arrangement to Qin LAN and explains the reason at the same time: "I was going to ask Bruce Lee to send someone to take care of it, but after thinking about Bruce Lee, I can believe that the people under him may not be good. It''s not good if I spoil it or break it, so I''d better ask Mrs. Long to take care of it."


    "Well, Qing Yan and Qing Xin are more reliable than Bruce Lee''s men." Qin Lan also agrees with Chen Xin''s choice.

 Chapter 202

    As the municipal government, which has mastered the resources of a city, it is very fast to provide the materials Chen Xin needs.


    If it wasn''t for the transportation of materials, they could even deliver things to Chen Xin''s house in a day.


    However, even so, the city government quickly prepared what Chen Xin needed.


    Chen Xin also contacted Mo Qingyan, explained the situation to her, and asked her to help take care of the shelter while she was not at home.


    For Chen Xin''s request, Mo Qingyan agreed after a little thought.


    But she also raised a problem, that is, she and Mo Qingxin can''t take care of Chen Xin''s shelter, especially the crops in the greenhouse. They don''t know how to take care of the crops.


    Mo Qingyan had hardly managed the fish vegetable Symbiosis System Chen Xin had given them before. That is to say, according to the precautions Li Wensheng told her, she poured some water every day and paid attention to the fish not to die.


    So let the two of them take care of Chen Xin''s greenhouse. What they can do is to water it on time. Maybe even harvesting can only pull out the whole plant.


    And they need to look after their own shelter. If the two sisters move in, their own home will become a problem.


    As for running on both sides, it is obviously impossible in the current environment.


    But these two things are not difficult to solve. Ding Ning, Mo Qingyan''s shelter, says she can help take care of them. After all, she has lived there before, so it''s not a big problem.


    On the other hand, Chen Xin said that he would transform the shelter before leaving, adding a monitoring program to the greenhouse, which would automatically prompt what needs to be done, so as to ensure that Mo Qingyan and Mo Qingxin do not have to worry too much about taking care of them.


    This kind of intelligent monitoring program is nothing new. The vegetable planting box, which was popular for a period of time before the disaster, has this function. It can monitor the growth status of crops and the environment of the planting box at any time, and prompt whether it needs watering, fertilizing and adjusting the light.


    Even some greenhouses and greenhouses before the disaster have the same function, but the corresponding cost will be very high.


    For Chen Xin, to achieve this function, it''s just to add an option when upgrading. It''s not a problem if it can be solved by survival.


    After confirming these things, Mo Qingyan also agrees to move in before Chen Xin leaves. What Chen Xin needs to do is wait for the materials from the city government to come, and then realize the first overall upgrade of the long prepared refuge.


    the city government is preparing materials, and Lu, who lurks around Secretary Li, also passes on the relevant information obtained from Secretary Li to AZU.


    AZU, who received the news, also asked Laosi to prepare with Laosan and Laoliu. They planned to disguise as a truck transporting materials from the municipal government before the truck arrived, and then seize Chen Xin''s refuge.


    In order to achieve this goal, in addition to the third and sixth pretending to be delivery men, the fourth specially selected more than 20 capable men to hide in the car at that time, as the backhand to deal with the accident.


    However, the old three felt sorry that they only had a dozen local rifles and pistols made by themselves after the disaster, and they didn''t even have decent weapons.


    After all, this is the country of Yan, the country with the most strict gun control in the world. It''s because they found a craftsman who can make clay guns after the disaster.


    Thinking of this, Lao San can''t help remembering the old days. At that time, why did they worry about weapons? As long as you have money, you can always get what you need.


    Unlike now, money is a piece of waste paper, weapons and food are the most powerful things.


    And they, not only can not get any weapons, even food is just barely self-sufficient.


    It is also because of dissatisfaction with this situation that AZU and his brothers want to occupy the city.


    If they can control a city, they will not have to worry about food or weapons, right? At that time, some people will have guns and food, and they will certainly be able to do a great job as AZU said!


    Third, thinking in this way, he was more concerned about seizing Chen Xin''s refuge.


    You know, it''s a shelter where you can exchange fresh vegetables with the city every month! Fresh vegetables in today''s world, but the real scarcity of materials!


    In addition, the refitted car that they saw when they were monitoring the shelter, which could drive normally in the snow, was also enough to attract the third man.


    It not only means that they can take advantage of mobility, but also shows that there are machining equipment and at least one person who knows how to machine in that shelter.


    This is very important to them!


    Because the equipment of mechanical processing and the talents who know how to process means that they can make their own guns!


    The craftsman AZU found who can make his own muskets can only make muskets with a few simple tools. If he has professional machining tools, he believes that he can at least make decent guns instead of only making iron sand and steel balls."Third and sixth, you already know the details, so I won''t say anything more." Old four found the other two brothers and explained to them: "tomorrow, when you enter the shelter, you will subdue the people in it as soon as possible, and try not to kill people. The people in the shelter are very helpful to our career. We need such people."


    "Don''t worry, old four. Old six and I know how to handle things properly. We won''t miss things." Old three just laughed at old four''s advice and didn''t think much of it.


    They are all lawless mercenaries who have been fighting for a long time. Even if the level of fighting is not comparable to that of the active servicemen of a military power, they are also a group of veterans who have been fighting for a long time.


    Third doesn''t think there are people who can treat them in that shelter. In the final analysis, they are just a civilian and two policewomen. Even if they have guns, third thinks that it will take a little effort for him and sixth.


    Fourth, of course, he trusted his brother''s ability, but he said a few more words: "it''s the key point to control the people. The materials transported by the city government to this refuge should also be eaten, and they should not be found, so you must disguise at that time! This shelter is for us to use as a stronghold. It can''t happen again when someone ran away like last time! "


    Talking about the last time someone ran away, Lao Liu''s face became a little embarrassed and ugly.


    What Laosi mentioned was the father and daughter who froze to death outside Chen Xin''s refuge last time. At that time, when the father and daughter ran away, it was Lao Liu''s turn to guard the captives. Because he couldn''t control himself for a moment, he was attracted by the little girl''s mother and agreed to give the father and daughter some preferential treatment, which led to their escape.


    For this reason, he was reprimanded by AZU and killed all the people in the shelter himself. However, the shelter became useless. Originally, they planned to turn the shelter into a stronghold.


    At this time, old four brought up the old story again. Although old six understood that it was just telling him not to make mistakes, old six still felt very embarrassed. For a moment, he was cold and didn''t want to say anything.


    Or old three played a round, said to old four: "don''t worry, old four, I look, there will be no problem. I know you like to play. When it''s over, I''ll go and tell AZU that the two policewomen have given it to you. You can play whatever you want. Now don''t miss the point. "


    "I see, third brother." By old three so a pass to say and, old six this just don''t want to nod.


    Chen Xin also made some adjustments to the shelter for Mo Qingyan and Mo Qingxin, who are planning to move here to help take care of their shelter.


    Qin LAN naturally moved to his room, while Ding Ning was going to move to Mo Qingyan''s shelter after Chen Xin left, and the room here was given to Mo''s sisters.


    As for Qin LAN, because she is still on holiday, she will stay here for a while before returning to the SWAT team.


    "Ah Xin, your room is the same as before." Qin LAN looks at the quilt spread out on Chen Xin''s bed and can''t help laughing.


    When they were dating before, she knew that Chen Xin didn''t have the habit of making quilts. Now when she saw that his bed was as messy as before, she couldn''t help feeling kind.


    Chen Xin didn''t say anything about it. The stage of embarrassment caused by this kind of thing has long passed. He and Qin LAN have long been used to each other''s small problems in life.


    "I''ll sleep in the upper bunk. Alan, you can sleep in the lower bunk. I''ll clean up later and change the sheets, quilts and pillows." Chen Xin still didn''t let Qin LAN sleep in the upper berth.


    Qin LAN doesn''t care about it. After living here for so many days, her shoulder is almost as good as before. Although she still has some pain, the healed wound doesn''t affect her action any more.


    Watching Chen Xin put her things in the cabinet of the room, Qin LAN noticed Chen Xin''s weapon cabinet and workbench, went to the workbench, looked at the tools on the workbench, and asked Chen Xin, "it''s not enough for you to have a workbench outside. Do you want another one in the room?"


    "The one outside is for other things, and this one is for weapons." Chen Xin didn''t cover up the real use of this workbench in front of Qin LAN. Moreover, he said that Qin LAN had seen this workbench when he stayed with him in his bedroom last time: "besides ordinary weapons, guns can also be made. Do you have any favorite or habitual weapons? I''ll make one for you? "


    "Can you make a gun?" Qin LAN took a surprised look at Chen Xin, but didn''t feel surprised. After thinking about it, she said to him, "don''t use other things. Help me make a pair of finger tigers. It''s simple."

 Chapter 203

    In the early morning, although there is no difference between day and night, the method of timing left behind in the past has been preserved.


    The staff of the city government are ready for the supplies, and the trucks used to load the supplies are ready to leave.


    "The supplies have been loaded and ready to go." Secretary Li reported to a leader next to him. This leader is the person in charge of the city government''s ground source heat pump reconstruction project for this small shelter. At present, he is also the direct leader of secretary Li.


    As the Secretary of the municipal government office, the logistics of material exchange is within the jurisdiction of the office itself. With Secretary Li''s own efforts, it becomes his direct responsibility.


    The leader didn''t say anything about Secretary Li''s report. He just looked at his watch and nodded to Secretary Li: "have you contacted with him?"


    "We have already informed the other party that we are going to transport materials, and the other party also knows that we are going to transport materials." Secretary Li nodded to the leader. In fact, he not only contacted Chen Xin, but also contacted his nephew, AZU, through Lu, and told AZU the departure time of the material transport truck on this side of the municipal government.


    The leader didn''t know what Secretary Xiaoli was doing in the middle, but nodded with satisfaction and said to him, "time is almost up. When you''re ready, let''s go. Xiao Li, you''ve made this trip."


    "Yes, yes!" Secretary Li busily nodded to the leader, quite a bit of flattery: "leader, do you have any instructions? If not, I''ll go. "


    "Let''s go. Be safe on the way." The leader was very kind and gave Secretary Li a smile.


    With the permission of the leader, Secretary Li got on the material truck and let the driver drive away.


    Looking at the departure of the material transport vehicle, the leader put away the friendly smile on his face and said to the people beside him: "inform the comrades of the municipal bureau that the bait has started."


    At the same time, AZU also received a message from Luu. He said to the third and sixth people who were ready: "let''s go. The city''s transport car has already started. My second uncle is in the car. He will help you delay for half an hour."


    "Don''t worry, Zuge. Ten minutes is too much for this kind of thing. In half an hour, we will definitely handle it well." Old three made a promise to AZU, while old six secretly winked at old three.


    Thinking of his promise to Lao Liu, Lao San was annoyed that his brother was not sensible. However, he was also hindered by his promise and said to AZU: "brother Zu, you know Lao Liu''s fault, the two policewomen in the shelter Can you give it to him afterwards? "


    "Lao Liu can''t control himself again?" AZU took a look at old six standing beside old three, but he was not angry.


    However, after some consideration, he shook his head: "we need to attract the talents in the shelter. These two policewomen may have something to do with each other and can''t be wasted."


    "Ah? Zugor Old six heard a Zu say so, the expression on the face immediately became discontented, quickly looked at old three: "third brother, this is what you promised me! You can''t eat your words


    When Lao Liu made such a fuss, Lao San couldn''t get off the stage. He looked at AZU and said in embarrassment: "brother Zuge, Lao Liu has such a hobby. I also promised him. Look at this..."


    However, AZU just shook his head, but perhaps considering that Lao Liu''s plan would be affected if he was not appeased, he compromised and said, "you can''t move the two policewomen now. When we control the city, I''ll find you two other women."


    It''s a great concession for AZU to make such a promise. Lao Liu also knows that AZU has always said that he is not good at it. Although he still feels a little dissatisfied, he stops when it''s good. Instead of saying anything more, he gets on the truck ready with Lao San and drives off.


    In addition to the old three and six, there are about twenty men hidden in the car. If the plan doesn''t go well, they will be the guarantee to seize the refuge by force.


    Looking at the truck driving out, AZU didn''t know why he was worried. However, he shook his head and let this worry out of his mind. He felt that he was worrying about something.


    But on one side of the old four see the action of AZU, can''t help but comfort him: "AZU, don''t worry, although old six is not reliable, isn''t there old three? They''ll take care of it. "


    AZU gave Lao Si a smile, nodded and said, "I believe Lao San, but Lao Si, on your side, the whole plan should be pushed forward as soon as possible. If the municipal government really transfers resources from other places, it will disrupt our whole plan."


    "I''ll take care of it. Don''t worry!" Old four assured AZU.


    After receiving the communication from the municipal government, Chen Xin is also preparing to receive materials and upgrade the shelter as a whole.


    He made a lot of space in the storage room for storing materials later. He also made a detailed inspection of all parts of the shelter to ensure that there was no problem, or that the overall upgrade would bring him any trouble or inconvenience.Chen Xin had never tried to upgrade the whole shelter before, so he had to make sure that every place in the shelter had an accurate arrangement in his mind. Otherwise, because of his brain heat, he would be very embarrassed if he wanted any fancy functions.


    Chen Xin is doing his own business, and Ding Ning and Qin LAN are not idle.


    Of course, the two of them knew that the city government wanted to take advantage of this fishing event, so after receiving the notice from the city government, they had changed their equipment.


    Qin LAN is holding his sniper gun came to Chen Xin after the upgrade of the observation room, the gun in the narrow observation port.


    The view here is very good. With her night vision and infrared sight, Qin LAN can monitor all the people coming from the front of the shelter even if she doesn''t have an observation hand.


    The flat gentle slope in front of her gives her a panoramic view of everything in her sight, even without a raised mound, which is the most challenging terrain for a sniper, because no one can avoid the aim of a sniper in this terrain.


    Qin Lan was sleeping in Chen Xin''s room last night, and Chen Xin naturally didn''t hide from her about the two double outfits at the gate.


    Although surprised by Chen Xin''s ability to make makchin, Qin LAN doesn''t intend to tell others about it, and doesn''t intend to expose it to others.


    That''s why she''s staying in the observation room at today''s low temperature close to - 40 ¡æ to prepare for sniping.


    Qin LAN hopes that she can use her own sniper gun to solve the enemy this time, instead of relying on the two widows who Chen Xin installed at the gate.


    If it was a peaceful time before the disaster, Qin LAN would never help Chen Xin hide all this, but now it''s the end of the world. According to Qin Lan''s understanding of Chen Xin, even if he has these things, he just wants to live more safely, instead of doing something he shouldn''t do with these weapons.


    So Qin LAN doesn''t mind hiding some secrets for Chen Xin, so that he can keep a card that can resist the threat.


    Because neither the city government nor the terrorists appeared, Qin LAN had leisure to think about these things.


    While she was thinking about these things, she also took down a pair of finger tigers that were originally hanging on her waist and played with them in her hands.


    This is the weapon she asked Chen Xin to make for her last night, a pair of finger tigers that look as beautiful as butterflies.


    In fact, tiger is very embarrassing. It is a kind of controlled weapon, and the police will define it as armed when judging. But in fact, the lethality is at the bottom of all weapons. The lethality may not be as good as a brick picked up by the roadside.


    People who don''t know how to use a finger tiger may even break their hands.


    But this kind of thing can play a great role in the hands of those who are proficient in fighting or fighting.


    Although it''s not as lethal as a knife, it can effectively improve the strike ability of fists. As for the use of scraping to increase the lethality of a tiger with a blade, although it''s not fatal, it will leave a rather ferocious wound.


    However, Qin Lan''s two finger tigers are small and delicate. They don''t have any edge or sharp spines on them. They just look like a pair of metal crafts with some aesthetic feeling. They don''t even look like weapons at all.


    But Qin LAN, who knows exactly what this pair of finger tigers are and what their functions are, will never think it''s just a pair of handicrafts.


    Because this is a pair of electric shock finger tigers, the high-voltage electric shock function attached to it is similar to the police electric rod, which can paralyze people at the moment of contact.


    The electric shock finger tiger certainly exists, but Qin LAN once saw it. It''s just a plastic product with two electric shock pieces on it. Its practical performance is not high. It''s not as simple and practical as preparing an electric torch.


    But this pair of finger tigers made by Chen Xin is not so fancy.


    The all metal material ensures that even if it has no electric shock function, it can also play the proper function of a finger tiger, which can effectively increase the blow effect of fists and protect fingers from injury.


    In addition, although Qin LAN has not tested its electric shock ability, she knows that if she really uses this pair of weapons, she only needs to hit the opponent with one punch to instantly put them down.


    It can be said that this is a pair of very practical non lethal weapons.


    When Qin LAN wants to try this pair of finger tigers, a light suddenly flashed outside.


    Qin LAN put her eyes on the infrared sight of her sniper gun and saw a truck coming towards her direction. She immediately got serious and said through the headset, "someone''s coming!"

 Chapter 204

    "Lao Liu, be smart for a while. Don''t stare at women." Sitting in the car, looking at the heavy metal door in front of the gradual settlement, the third is still telling the sixth.


    "Don''t worry, brother. I know the importance. I won''t let things go wrong in this kind of thing." Old six also know their own problems, in old three told him, did not feel old three annoying, just seriously nodded.


    Although both of them are veterans, they are a little nervous at this time. The sixth sense they have cultivated for many years makes them subconsciously feel that there seems to be some danger.


    "Be careful." Old three didn''t mean anything. He reminded old six. At the same time, he raised his vigilance. Then he got out of the car with old six.


    The gate of the shelter in front of them has been opened. Chen Xin and Ding Ning are standing at the gate together. However, Chen Xin has not lowered the gate completely, but only lowered about two-thirds of it, and one-third of it is exposed outside, just like a parapet.


    This is a special use of this gate. It can be lowered by two thirds and left one third outside. It can be used as a necessary shelter so that people in the shelter can face people outside without losing protection.


    "Are you the delivery people from the city?" Chen Xin didn''t mean to open the gate completely or come out of the shelter. He just stood behind the parapet like gate and asked old three and six.


    "Yes, comrade, we are here to deliver things to you. Can you open the door and let us in?" Seeing Chen Xin''s defensive posture, Lao San somehow felt more dangerous, but he still said hello to Chen Xin, trying to make him open the door completely.


    But Chen Xin was indifferent and asked them, "what materials have you brought? Is everything ready for me? "


    "Building materials, steel, comrade, we have all the materials you want. Do you think we can open the door so that we can drive in and unload the car? It''s cold out here. " The third pretended to be honest and honest and said something to Chen Xin, just to cheat the door in front of him.


    Although the metal gate dropped by two-thirds, it was just a sprint for him and the sixth mercenary, but the exposed part of the metal gate was still chest high. It was obvious that the car could not drive in anyway.


    And there were only two people in front of them, and there was a policewoman who didn''t know where she was. In case when they rushed in, others were already ambushing with guns. Didn''t they rush in and die?


    The safest way is to drive the car in directly, and let more than 20 people on the car rush in. It''s the best policy to subdue all three people. If it doesn''t help to lower the "breast wall" in front of us, the people they bring will be able to rush in better.


    However, Chen Xin was obviously indifferent to this. He just shook his head and said, "I''m sorry, the gate seems to be frozen. It can''t come down. You work hard. Just unload the truck."


    Chen Xin said so, and specially extended his head to look out, as if to give the old three advice, said: "you can reverse the car, put the rear of the car at this side, unload the goods directly, we''ll just pick it up here. If you come in to unload the goods, you''ll have to help move them, so that you can save some work. "


    After hearing this, Lao San felt like swearing. Is this something to save?


    I don''t need you to save trouble, I just need you to open the door! If you really want to save something for me, it''s the easiest to open the door and surrender!


    However, although he was full of swearing in his heart, the third man could only flatter him and said, "there are a lot of things on the car, so it may be difficult to unload them. Moreover, we can help, can''t we? Where is the door frozen? We have hammers in the car to help with the de icing. "


    With that, old three seems to be really trying to help de icing, and comes to Chen Xin''s side. He seems to want to see where the gate is frozen.


    Old three is walking this way, old six is going to the back of their truck, as if to get tools.


    However, seeing their actions, Chen Xin''s eyes narrowed and a smile appeared at the corner of his mouth, as if everything was in his expectation.


    He didn''t stop the old three''s action. He just winked at Ding Ning and walked towards the door, but he walked towards the side of the door, looking like he was going to check the switch of the door.


    Third, there is no doubt about him. Sixth, at the end of the truck, is calling his men to get off the truck. They think they have got the plan. Chen Xin has been taken in, but they have never thought that their every move is actually monitored by Qin LAN in the observation room above.


    "Xin, be careful! There are still people on the other side''s car! " Qin LAN issued a warning to Chen Xin while sticking her eyes on the aiming glass, aiming at the people who got off the car, ready to shoot at any time.


    Listening to Qin Lan''s warning in the headset, Chen Xin''s eyes flashed a certain look, but he didn''t say anything. He just stood by the gate.


    Although it seems that he is checking the door switch, the remote control that controls the door lifting is always in his pocket. He can close the door at any time.


    Third, he didn''t know that they had been exposed, but he was still enthusiastic. He pretended to check the gate and said to Chen Xin, "comrade, there seems to be no problem outside. Would you like to try again and see if you can open it? Or I''ll go in and check it for you. Is it frozen inside? "Third, he wanted to climb up the "breast wall" and turn into the shelter.


    Chen Xin just said with a smile: "OK, I''ll try to open it."


    While saying this, he pressed the remote control in his hand and raised the door again.


    Seeing the gate rising, the third man was in a hurry. He turned over the wall and cried out: "sixth man!"


    Hearing the cry of old three, old six also knew that things had changed, and yelled "follow me!" to the car He rushed towards the gate of the shelter.


    Old three''s skill is not bad, although the door is rising, but he quickly turned in, but when he wants to rush to subdue Chen Xin, Ding Ning has taken out a pistol at him, shouting: "don''t move! Hands up


    At this time, the gate of the shelter behind him has risen to half of the position. Chen Xin has also opened the secret door beside the gate and grasped the grip of a double mounted Markham machine gun.


    Third, he doesn''t know what Chen Xin is doing. The problem of angle makes him unable to see the machine gun hidden in the wall. He thinks it''s just the control switch of the gate, but he doesn''t hesitate. Instead, he squats down and pounces on Ding Ning, trying to grab the pistol in her hand, subdue her, then subdue Chen Xin, and then lower the gate again.


    "Bang!" The gun went off.


    On the other hand, Secretary Li is trying to slow down the city government''s material transport vehicle.


    "Master, the snow is so deep on the road. Drive slowly and pay attention to safety. We are not in a hurry anyway. It doesn''t matter if we are late." Secretary Li said to the driver. On the surface, he was worried about safety, but in fact, he was just procrastinating.


    But the driver didn''t care. He just nodded and said, "don''t worry, leader. I''ve been driving for more than ten years. I''m steady! There will be no problem


    In the face of such an attitude of the driver, Secretary Li didn''t say much about it, so he couldn''t keep talking.


    Delaying the speed of the car is just one of secretary Li''s means. The real plan to delay time is to let AZU''s men block the car''s way ahead of time and force the car to change its way.


    They didn''t plan to park the car on the road, which would be too obvious.


    So what AZU asked Secretary Li to do was to make a detour and drive slowly, trying to buy time for old three and old six to seize Chen Xin''s refuge.


    Secretary Li participated in the planning of the forward route of this material transport vehicle. He knew that there was a key position on this route. After blocking it, he needed to make a big circle. Even before the disaster, he had to delay at least 20 minutes. Now in this kind of environment, this detour would take half an hour.


    As for the roadblocks, of course, Secretary Li doesn''t need to worry. Lu, who got the line from him, will inform AZU''s men to do it.


    Sure enough, when the material transport vehicle arrived at the bridge leading to the outside of the city, there was a car across the bridge, which seemed to be trapped in the snow.


    "Leader, there seems to be a situation ahead." The driver master naturally found out the situation in front of him and asked Secretary Li how to deal with it.


    "Ask about the situation first, and help if you can." Secretary Li has a kind-hearted appearance, and has nothing to say.


    Of course, he knows that the car in front of him was prepared by AZU''s men. He can choose to make a detour, or he can choose to ask the material transport vehicle to help pull the car out of the snow to get through the line. The two will take about the same time, but the delay of the trailer will be less.


    It''s just that Secretary Li is a little strange. The footprints around the car trapped in the snow are in a mess, and the ground is trampled in a mess.


    This made him feel annoyed. He felt that the work of AZU''s men was really bad.


    The driver stopped the car slowly. It seemed that he went to inquire about it. Then he came back quickly and said to Secretary Li, "leader, their car is stuck in the snow. They want us to help drag it. Do you think we can help you?"


    "Will it take time?" Secretary Li also pretended to take a look at the watch, and then said to the driver: "if it doesn''t delay our business, please help us."


    "Good! It''s a matter of ten minutes. It''ll be ready in a minute. They''re not in a serious trap. " The driver took the tools out of the toolbox and got off to work. Secretary Li looked at the driver''s work and felt a little relieved.

 Chapter 205

    Unlike what Secretary Li expected, with the help of the driver, the car was quickly pulled out of the snow. It didn''t even take more than five minutes.


    Looking at all this, Secretary Li faintly felt that something was wrong. It was obviously different from the arrangement of AZU''s side to easily pass through the roadblock, but it was obviously impossible for him to directly ask the driver why he was finished so soon.


    It''s just that Secretary Li can''t ask the person next to the car why he didn''t delay. After the driver picked up his tools and got on the bus again, he asked him vaguely, "master, what''s the matter with that car?"


    "Oh, it''s nothing. Their front wheels are stuck in the pit. They can''t get out of the wheel. I helped them and they fell out by themselves." The driver answered Secretary Li''s question with a smile, but suddenly he said to Secretary Li, "leader, I didn''t delay, did I?"


    "Oh oh No, no, go on! " Secretary Li was startled by the driver''s words and quickly signaled him to move on.


    The material transport vehicle continued to move forward, but the car that broke away from the snow pit did not move forward. When the tail light of the material transport vehicle disappeared from sight, the people on the vehicle started the car, but they did not drive outside the city, but turned around and returned to the urban area.


    Secretary Li, of course, doesn''t know what happened to the car behind him. At this time, he is sitting on the material transport vehicle, watching the car getting closer and closer to the target. He is also more and more worried that AZU''s men haven''t robbed Chen Xin''s refuge, racking his brains to think about what else can delay the time.


    "Master, can you pull over? I want to go to the bathroom. " Secretary Li held on for a long time, and finally thought of a way to delay a little time.


    However, the driver looked at him in surprise, reached out and took out an empty plastic bottle and handed it to him: "do you go to the toilet outside in this weather? Aren''t you afraid to freeze you up before you finish peeing? Use this. Sprinkle it in the car. I''ll open the window. It''s easy to smell


    Secretary Li looked at the empty plastic bottle handed over by the driver. She didn''t take it either. She froze awkwardly for a moment.


    Noticing that Secretary Li froze, the driver finally laughed, but the smile was inexplicably cold: "why, can''t you pee? They''re all big men. Why don''t you dare to see people? "


    At this time, Secretary Li noticed something was wrong and quickly said, "no, I''d better bear it for a while."


    "That''s OK. Hold it. Don''t pee in your pants!" At this time, the driver was not polite to Secretary Li. After throwing the plastic bottle to him, he stepped on the accelerator to make the car faster.


    At this time, Secretary Li did not dare to say anything more. He could only hope that AZU was finished and would not let him reveal his identity.


    The driver didn''t pay attention to Secretary Li any more. He firmly believed that Secretary Li didn''t dare to open the door and jump to escape.


    Don''t say if he will jump to death, just such a cold day, even if he jumps, where can he go? He was frozen to death in the snow.


    What''s more, although it''s a truck, there''s no saying that someone jumped down and couldn''t catch up.


    While driving, the driver, instead of pretending to be honest, asked Secretary Li, who had already guessed his identity: "what''s the real name of that woman in your family? When did she show up at your house? "


    "She..." As soon as Secretary Li heard the driver''s question, his heart immediately cooled. He knew that he was exposed, but he still wanted to struggle: "master, which woman are you talking about? I''m the only distant niece in my family... "


    "Oh, it''s quite like that! But it''s a pity that we have found out for a long time that you can still fight for a lenient treatment if you tell us now. If you refuse to tell us, it''s resistance and strictness! " The driver changed his attitude directly.


    After being drunk by the driver''s master, Secretary Li''s last fluke was broken, but he still asked: "you Who on earth are you? "


    "Hum, Li Minamata, leader of the second squadron of the first brigade of the city special police detachment! I thought you were passing information to your nephew through terrorists disguised as cleaners in the name of smoking. We don''t know? " The driver master shows his identity. It''s Qin Lan''s old boss, Li Tou: "think about it carefully, think about the problems that should be explained clearly, and when you enter the interrogation room, save yourself some effort, and also save us some effort."


    Listening to Li Tou''s identification, Secretary Li collapsed on the seat. The plastic bottle that Li Tou had thrown to him also rolled off his hand and fell on the floor of the cab.


    And a pair of bright silver bracelets also handed to his hand: "put it on yourself."


    when Li Tou drove to Chen Xin''s shelter, he was startled by the bright red he saw.


    At least seven or eight bodies fell on the ground with their backs toward the shelter, blood flowing all over the ground and scarlet the snow under them.


    Close to the gate of the shelter, a lorry was parked in the same place, with more than a dozen bodies lying in a pile, as if they were all shot when they tried to rush into the shelter.Seeing this scene, not only Secretary Li in the car almost peed in his pants, but also Li Tou felt fluffy. He quickly took out his walkie talkie to contact Qin LAN, for fear that a bullet from nowhere would snipe him.


    "These two wenches, can''t they kill crazy?" Li Tou muttered and called Qin LAN: "Xiao Qin, I''m Lao Li, can you hear me?"


    "I can hear you, Li Tou. Here you are at last." Qin Lan''s voice came from the walkie talkie, but with a trace of fatigue: "I can see you, so let a Xin open the door for you."


    Finish saying, Qin LAN hang up communication, let Li head want to ask want to say all hold back to go back, can only side uneasy waiting for the shelter to open, while trying to look around looking for Qin Lan''s position.


    But his uneasiness didn''t last long, and the gate of the shelter soon came down again.


    Li did not dare to drive the car in the past, for fear of running over the body, so he hit a steering wheel, pulled the car to one side and said to Secretary Li: "get off the car, don''t try to play tricks, there are snipers here."


    See Secretary Li obediently out of the car, Li head this just get off the car, although the face with a mask, but a bloody smell or let him almost want to spit out.


    Soon Ding Ning came out of the shelter and said hello to Li Tou: "Uncle Li, you are here. Go in and say it."


    While saying that, Ding Ning also looked at Secretary Li and asked Li, "is this the inner ghost of the city government?"


    Li Tou nodded and didn''t say anything more. He just urged Secretary Li to go to the shelter and asked Ding Ning: "what''s the matter with the corpse at the door? Are you sweeping with machine guns? Your dad got you submachine guns? "


    "My father is not so generous. A Xin made this. He made a submachine gun himself." Ding Ning obviously knows what happened, but she deliberately conceals the situation for Chen Xin: "this guy is too practical. He made a Chicago typewriter according to the drawings he found on the Internet."


    "Chicago typewriter?" Li Tou looked at the corpse on the ground and shook his head. Obviously, he didn''t think that the Chicago typewriter could cause such terrible damage, although it was also a very famous gun.


    However, Li Tou did not expose Ding Ning''s "lies", but escorted Secretary Li and Ding Ning into the refuge together.


    In the shelter, novice Chen is holding a Chicago typewriter, while old three and old six are all collapsed on the ground, their hands are all handcuffed, and old six''s leg is still tied with a bandage, bleeding out.


    "Li Tou, you are a little late! We''ve solved the battle. " Chen Xinchong Li Tou is joking, although his face is very pale.


    Li Tou took a look at his Chicago typewriter. He already knew the situation in his heart, so he said with a smile: "you''re lucky to say that I''m in a hurry to help you. As a result, the three of you are so good that two of you are left alive!"


    "I can''t blame them for this. They rushed to my house in a swarm. I was scared and didn''t stay." Chen Xin deliberately said the lines he had just discussed with Qin LAN and Ding Ning in a embarrassed tone.


    Qin LAN doesn''t want Chen Xin''s heavy machine gun exposed, and Ding Ning naturally doesn''t want to tell his secret, so they come up with such a move.


    As for Chen Xinxian''s Chicago typewriter, it was made by Chen Xinxian. As for why he used this kind of gun as a cover up, it''s just that the caliber of the Chicago typewriter is the same as that of Maxim.


    Li Tou listened to Chen Xin''s statement, but he had no intention to investigate what was going on. For Chen Xin, it was nothing more than excessive defense and illegal possession of guns. However, in the present eschatological environment, no one would go deep into these two things.


    So he just nodded and said, "OK, it saves a lot of work to have no living. It''s just a little trouble to collect the corpse. What''s the situation with these two people?"


    "The two of them should be the main figures of the terrorist gang. Before, they were two drivers pretending to deliver goods. They tried to rush in and open the gate of the shelter. As a result, they were both overturned by dinning. And mercenaries! It''s a really low level. " Chen Xin explained the situation to Li Tou, but he did not forget to despise the two prisoners on the ground.


    Hearing what he said, old three and old six felt sad and indignant. They were not inferior at all. The reason why they were put down by Ding Ning alone was that besides Ding Ning had a gun, Ding Ning also had electric shock weapons made by Chen Xin in his hands. They were all put down by that pair of electric shocks.


    After all, no one will be able to stand up after being hit by a fist wrapped in tens of thousands of volts of high-voltage electricity.

 Chapter 206

    Old three and old six were led into the car by Li Tou, waiting for them will be a fair trial.


    As for the incomplete corpse on the ground, it was cleaned by the professional corpse collection team. It was just the scarlet blood on the snow and some residual limb fragments, which were really difficult to clean up. They didn''t have any trouble. They just took a shovel and shoveled the frozen red ice into the body collection bag, leaving only a dark red bloodstain.


    "The Chicago typewriter is about the same caliber as those bullet holes, but the submachine gun doesn''t work that way, does it?" Looking at the body dragged away, Li Tou whispered to Qin LAN who had come down from the observation room.


    Of course, Qin LAN knew that he couldn''t hide it from Li Tou, but he just said in a low voice: "we haven''t written the report yet, just don''t know about it."


    Being choked by Qin Lan''s words, Li Tou could only shake his head: "OK, but it''s a serious matter that someone has a heavy weapon. If it''s found out..."


    "Ah Xin is not a man who will mess around. He is just a card to protect himself. No one will check this." Qin LAN doesn''t think that Chen Xinhui is the one who has taken the important weapon to make trouble, and she doesn''t worry too much about being found out.


    After all, the times have changed. In the present eschatological environment, there will still be people who really want to investigate this kind of thing. But there is a justifiable reason to cover it up, and no one will hold on to it and have to turn it over.


    Li Tou thought about it, and it is true. When these corpses were taken back for autopsy, they were only written in the autopsy report that they died of gunshot wounds. As for the gunshot wounds that were swept to death by heavy machine guns or by submachine guns, only professionals can understand the difference between them.


    Even if the forensic doctors write it as it is, the leaders above will not read it carefully, or even read the autopsy report at all. They will only listen to the report about how many criminals have been killed.


    As long as no one deliberately mentions this matter, as Qin Lan said, after covering up, no one will be bored to find out whether a group of terrorists were killed by heavy machine guns or submachine guns.


    After all, this is the end of the world. Even if the terrorists are alive, they will start to work hard for ten years or even send away a peanuts.


    Thinking of this, Li Tou didn''t say anything more, just nodded: "I''ll say hello to the people in the corpse collection team."


    Seeing that Li Tou was willing to help, Qin Lan also said thank you to him. At the same time, he took out a wine bottle full of "water" and handed it to Li Tou: "it''s hard to drive here. Take a drink to quench your thirst."


    "This I''m really thirsty. " See Qin LAN handed over the wine bottle, Li head face burst out a smile.


    When Li Tou drinks "water" to quench his thirst with a wine bottle, Chen Xin is counting the materials brought by Li Tou.


    Although this is a fishing plan, the materials transported by the material transport vehicle are real. The municipal government is really preparing to open a small shelter and try to install the ground source heat pump designed by Chen Xin to heat the shelter.


    If this plan can work, the city government will gradually open the previously closed small shelters, and redistribute the population in the large shelters.


    The first reason why the population of small shelters was concentrated in large shelters was because of the oxygen problem. After all, the oxygen generator only covered large shelters and medium-sized shelters, and there was no oxygen generating equipment in small shelters.


    Another important factor is that the heating problem is not easy to solve.


    Now with Chen Xin''s ground source heat pump, this problem will no longer become a problem of restriction. Heating is solved. The problem of oxygen can be solved by building a greenhouse in a small shelter and using the plant light cooperation to produce oxygen. In this way, the living conditions of the small shelter can be improved and the survivors can be accommodated again.


    Since the city government learned that there is a ground source heat pump which is much more energy-saving than coal-fired boiler heating in the SWAT team, it has always attached great importance to this matter, and even when arranging the arrest of terrorists, it still did not forget the promotion of this matter.


    We have not only prepared enough materials for Chen Xin, but also the raw materials needed for the manufacture of ground source heat pump. If we were not worried that Chen Xin would not be able to pile up here, we might have shipped them together this time.


    However, even so, according to Chen Xin''s list of materials, enough materials were sent to make ten ground source heat pumps.


    Secretary Li was supposed to be in charge of transporting these materials and talking with Chen Xin about the ground source heat pump, but now he is arrested as a terrorist''s accomplice, so it''s natural that someone else will come to talk with Chen Xin about this.


    It was the former leader of secretary Li who came to talk about this with Chen Xin.


    "I''m so sorry, Comrade Chen. We didn''t do our work well. You were surprised by this." The leader arrived at Chen Xin''s shelter shortly after the corpse collection team left. As soon as he met, he said hello to Chen Xin very politely.


    Chen Xin didn''t really take the politeness of the leader seriously. He just said hello to the leader with a smile. He also said politely: "the leader is polite. Cooperating with the municipal government to fight against terrorists is also to protect my own safety. This is what I should do. It''s cold here. Why don''t you go in and talk? "Chen Xin said that he invited the leader and himself to the shelter to talk about the ground source heat pump.


    When Chen Xin talked with the leaders of the municipal government about the ground source heat pump, AZU and his brother were being encircled by the special police and the armed police.


    "What''s the matter with TM! How did the police find us? " Old four side to prevent the hands of resistance, while to AZU loud persuasion: "AZU, let''s run! If it goes on like this, all the brothers have to be explained here! "


    "I don''t believe it! How can they possibly find us here! " AZU at this time a pair of manic appearance, his face is not reconciled and can not believe.


    It''s really no wonder that AZU was unwilling. Before he was blocked by the police, he was still thinking about how to occupy Chen Xin''s refuge, how to use the output and materials in his refuge, and how to develop his own power by taking advantage of the shortage of materials in the city government, and then control the city at one stroke.


    As a result, in the twinkling of an eye, the police not only blocked the shelter, but also killed many of his subordinates in the resistance just now. Even three of his brothers died under the police gun.


    AZU has only six brothers in all. Lao San and Lao Liu went to Chen Xin''s place, and now they are estimated to have been caught by the police. Three of the remaining brothers died, leaving only Lao Si, who is still organizing resistance.


    As for the group of people he brought back from Southeast Asia, several of them were already lying on the ground and out of breath. Only a few of them resisted under Lao Si''s organization, and at the same time, they scolded Yue language and let AZU run away.


    Although the shelter they blocked is just an ordinary village shelter, according to the design, there is only one exit at the gate, AZU''s men still dug an escape passage here for emergency use, and now is the time to make this passage work.


    But AZU was very unwilling. He was unwilling that his brother would die, his ambition would end, and he would run for his life like a dog.


    He couldn''t figure out how the police came to the door and how he was exposed.


    "AZU! There are police outside. Let''s go Laosi persuades AZU that three brothers have already died, and Laosan and Laoliu are in danger. He really doesn''t want to be here with AZU.


    They have only a few inferior pistols and some local rifles in their hands. They can''t compete with the well-equipped special police and armed police in any case.


    The reason why they are still able to resist now is that they are stuck in the terrain and the police don''t want to cause too many casualties. After all, the two previous suicide attacks are enough to show that these terrorists have soil bombs on their hands and they are not stingy with suicide bombers.


    But now they don''t have any soil bombs, and the three previous explosions have used up their stocks.


    The reason why they are still resisting now is that they know that even if they are caught, they will die, and there is an escape way to escape.


    "But did the second, fifth and seventh die in vain?" AZU still can''t persuade himself to escape like this, although he knows that resistance is nothing more than being caught or dying.


    "Run, AZU! Only by surviving can we avenge them! There''s nothing left to die here! " Old four painstakingly persuades a Zu, the difference drags him to leave.


    Looking at another man who was hit in the head by a flying bullet, AZU bit his teeth and was dragged to the direction of the secret road by Lao Si.


    AZU''s men watched as AZU and Lao Si began to run away. The people they brought back from Southeast Asia were also very clever, fighting and withdrawing. Only a group of abandoned children who were used as cannon fodder by them were still resisting.


    But with the withdrawal of AZU''s core subordinates, their resistance became more and more weak, and soon a team of special police officers came in.


    The bodies of the terrorists killed on the ground did not attract the attention of these special police officers. They just checked whether there were any survivors and whether they were bound with bombs. They did not continue to pay attention. Instead, they quickly searched the whole refuge in order to catch the terrorists led by AZU.


    The special police officers soon found the secret road where AZU fled, and at the same time, they also reported the incident to Uncle Ding, who was commanding outside.


    "Run away? I know how to save my life! But can you run? " Hearing the report, uncle Ding, who was in charge of the command, didn''t say anything, but his heart was full of anger.


    For those special police who died before, he has already made up his mind to arrest AZU and their group.

 Chapter 207

    Under the pursuit of the special police, whether AZU, Laosi and his subordinates can escape is an undoubted question.


    Even if they can escape this time, where can they escape in the ice and snow? Yanguo is not a small country in Southeast Asia. Even if it is the last time, it is not difficult to catch a group of fugitives.


    However, Chen Xin doesn''t need to worry about this problem. After seeing off the municipal leaders who came to discuss the matter, Chen Xin has time to come to his storeroom to check the materials sent by the municipal government.


    By this time, Chen Xin''s storeroom was already full. All kinds of building materials and metal materials had piled up, leaving him nowhere to go. The materials consumed by upgrading his bedroom and car had been replenished.


    This also means that he is fully prepared for the overall upgrade of the refuge, and what he lacks is only an upgrade.


    Chen Xin plans to leave the overall upgrade for tomorrow. Although he already has enough materials and survival points, today, the door is full of blood. Although it has the meaning of red, it is still a bit unlucky.


    Chen Xin still cares about this, so he plans to wait for this important upgrade tomorrow morning.


    After all, the overall upgrading of the refuge is also a very important event for Chen Xin.


    "Ah Xin, what are you doing here? Do you count the materials? " Qin LAN didn''t go back to the city with others. She was still on holiday and stayed in Chen Xin for the time being.


    "Well, count out the materials and see if there is enough for the reconstruction. I plan to start the reconstruction of this shelter tomorrow. After that, I will start to pick up my parents." Chen Xin looking back at Qin LAN, she is still a special police combat equipment, but it is quite heroic.


    But today''s Qin LAN does not have any feminine weakness. She has just killed several gangsters who want to escape. At this time, she also shows a kind of hard to hide evil spirit.


    But today, Chen Xin is the most ferocious one. He uses a heavy machine gun to shoot the gangsters. The time of shooting is not even ten seconds, but the effect is extremely terrible.


    The effect of heavy machine gun strafing is definitely not like the one on TV where there is a bullet hole on the body, and then a real person can faint and fall down again, or roll around and stand up like a nobody and continue to fight.


    The caliber of the Markham heavy machine gun was 11.45mm in the early stage, and it was reduced in the later stage. The caliber of the m1910 was 7.62mm, but its power


    The m1910 uses a 7.62 ¡Á 54mm m1908r cartridge with a bottom edge, with an initial velocity of 860 meters per second. This is not a large caliber cartridge. However, after hitting the human body, although the front view is a small hole, the back view is a hole as big as a large bowl ramen.


    By Markham heavy machine gun fire, or double Markham, those people can have a complete body is lucky.


    In fact, the gangsters who were killed by Qin LAN were lucky. They had only one bullet hole on them. But most of the gangsters who were swept to death by Chen Xin were dilapidated. Some of the gangsters who rushed to the front even broke their bodies into several pieces, which brought great trouble to the corpse collection team. They had to use shovels to clean them up.


    But Chen Xin didn''t have any so-called evil spirit. He didn''t think too much when he pulled the trigger just now, but when all the dust was settled and he opened the door to wait for the corpse collection team to clean up the corpses, the ground was red, green, yellow It''s so close that he didn''t spit it out.


    That''s why Chen Xin''s face turned pale when Li Tou came.


    Fortunately, things have passed, Chen Xin is not the first time to shoot and kill, he has now recovered, a lot better state, have the mood to chat with Qin LAN here.


    "When I saw you for the first time, you were all in training clothes, right? At that time, I was still thinking about what kind of woman would wear training clothes on her first date. " Looking at Qin Lan''s combat equipment, Chen Xin can''t help but make fun of her.


    Hearing Chen Xin talking about the past, Qin LAN couldn''t help laughing: "speaking of this, you didn''t get much better then, did you? Other people don''t talk about dressing up in a suit on a date, or at least clean up yourself. Ah Xin, you didn''t even shave that day. "


    "Ha ha, I didn''t know it was a blind date that day. Xiao Ding told me to ask me to play games. I''m used to it at ordinary times, and Xiao Ding didn''t see me slovenly, so he simply cleaned up and went." Recalling what happened at the beginning, Chen Xin felt a little funny. At that time, not only was he cheated by Ding Ning with the excuse of playing games, but Qin Lan also had the same reason, so she appeared in training clothes at that time.


    At this point, the two of them couldn''t help looking at each other and laughing. The two people who didn''t leave a good first impression on each other were able to get together later. It''s really amazing that their fate is wonderful, although in the end they chose to break up because of some personality reasons.


    "Don''t say that, ah Xin. Are you going to leave after all these things?" Qin LAN and Chen Xin talked about the business and asked him, "are you going to go on the road alone?"


    Chen Xin nodded his head and answered positively, "I originally said that I was going to let you accompany me, but think about it. It''s too hard for you to accompany me all the way. Moreover, it''s my own private business. There''s no need for you to accompany me.""Why don''t you go to pick up your uncles and aunts, and I''ll go with you? My uncles and aunts used to treat me very well, so I should go to pick them up. " Qin LAN heard Chen Xin say so, still want to go with him.


    Qin LAN has even figured out the reason. She thinks she should be able to persuade Chen Xin to change her mind, even though she has never succeeded in this kind of thing: "and you also said that it''s a long way, and it''s more than 2000 miles to and fro. When can you drive alone? If I accompany you, how many two people can drive instead, and I still... "


    "You can stay and help me look after this place." Chen Xin looked at Qin LAN with sincere and serious eyes: "I know you want to go with me, but the problem is that I don''t want you to accompany me along the way. It''s my business, not your business."


    "But I..." Qin Lan also wants to explain, but Chen Xin raises a hand to her.


    "I understand what you mean, but Alan..." Chen Xin put his hands on Qin Lan''s shoulders and said to her seriously, "I''m going to pick up my parents. This is what I have to do as a son. You don''t have to take this risk with me.


    I don''t know if I can finish the whole journey and come back alive. You don''t have to go with me! If you really want to do something for me, take care of it for me, so that when I come back, I won''t even have my home. "


    "Didn''t you ask Qing Yan and Qing Xin to look after this place for you?" Qin LAN is not convinced by Chen Xin, just as she can''t persuade Chen Xin.


    Chen Xin smiles and says to Qin LAN, "long Niang and Xin Xiaomei want to live here for a long time, but do you think they can really hold such a big place here? With no one to look after? "


    Hearing Chen Xin say so, Qin LAN can''t help thinking about this problem seriously.


    How about Chen Xin''s shelter? If it is the initial state, it can only be said that in general, it is no problem to be a private nest, but it is not as much thought about by people.


    But with Chen Xin''s step-by-step use of the system for transformation and upgrading, other than his 30 cm thick metal gate, the official refuge does not have such a good gate!


    In addition, Qin LAN, who has lived here for a long time, can definitely say that there is no more comfortable and better place in the city than here.


    If Chen Xin himself is here, it''s easy to say that he relies on the two ferocious double couplets in front of the door, plus the trade and contact with the SWAT team and now with the city government, which is enough to stop the new people from thinking about him.


    However, Chen Xin was ready to leave immediately. He crossed more than 600 kilometers in four provinces and returned to his hometown to meet his parents. It''s not too much to describe his uncertain future and unpredictable life and death.


    Under such circumstances, Chen Xin entrusts Mo Qingyan and Mo Qingxin to look after his home. Although this is not impossible, the possibility of being missed is greatly improved. In particular, Chen Xin plans to carry out some transformation before leaving, which undoubtedly makes this refuge more attractive.


    At that time, if someone wants to force Mo Qingyan and Mo Qingxin back to their own home, and then occupy the place, which is called "looking after Chen Xin''s home", then even if Chen Xin can finally come back successfully, it will not be easy for him to take back his refuge.


    And by that time, it''s uncertain how much of what he''ll be able to keep in his sanctuary.


    Although Mo Qingyan and Mo Qingxin are not poor in ability, and have good relations with Qin LAN and Ding Ning, they are not Chen Xin after all. It''s good that they can maintain the material exchange with the special police every month. They can''t continue the cooperation between Chen Xin and the municipal government on ground source heat pump, and naturally they can''t enjoy the protection brought by these relations.


    So if Mo Qingyan and Mo Qingxin want to keep Chen Xin''s refuge, it doesn''t mean that they can''t, but there will be some problems.


    Qin Lan''s existence is more or less a force deterrent. After all, she is a sniper of the SWAT team. In a sense, she can represent the SWAT team to protect Chen Xin''s refuge.


    "If you want to travel so far alone, aren''t you afraid of danger?" Qin LAN looks directly at Chen Xin and still hopes to go with him.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 208

    Chen Xin finally convinced Qin LAN to agree to stay and take care of her shelter instead of following him to travel thousands of kilometers back home to meet someone.


    As for Chen Xin''s way of persuading Qin LAN, she naturally saw all kinds of weapons and equipment he had prepared on the tracked armored RV.


    Looking at Chen Xin''s radar, UAV and heavy machine gun installed in his car, Qin LAN knows that these things are enough for Chen Xin to protect himself along the way. As long as he doesn''t go with the army hardtop, ordinary robbers and so on, he can''t help his armored car.


    The only thing that worries Qin LAN is that Chen Xin is alone. If something happens on the way, she may not be able to deal with it in time.


    However, this is not a problem, Qin LAN did not continue to insist on accompany Chen Xin to go this trip, so after Chen Xin put out the weapons on the car, Qin LAN did not continue to struggle.


    Moreover, what Chen Xin said is also reasonable. Once he goes there for a month or two, she needs to help Chen Xin look after his home.


    With Qin Lan''s help and Mo Qingyan and Mo Qingxin''s help, Chen Xin has no worries about his home.


    Now we just need to upgrade a complete shelter and manufacture the ground source heat pump needed by the municipal government, and then we can start.


    In order to prepare for the upgrade, Chen Xin took a bath in the evening and went to bed early so as to give himself a good condition and wait for the upgrade of the refuge after getting up early tomorrow.


    Qin LAN has moved to his room, but this evening, no matter he or Qin LAN, they didn''t say they wanted to do something intimate. Chen Xin climbed up the upper berth and soon fell asleep.


    Qin LAN sleeps in the lower bunk, listening to Chen Xin''s even breathing sound in the upper bunk, and soon goes to sleep. However, the corners of her mouth are slightly tilted up, with a satisfied smile on her face.


    The next morning, Chen Xinqi got up very early, even earlier than Qin LAN, who always got up early.


    After washing and preparing breakfast, Chen Xin shouts Qin LAN.


    Ding Ning had to go back to the Municipal Bureau to report the situation yesterday, so he left with them yesterday. Only Qin LAN stayed here because she was still on a convalescent leave.


    So there were only two of them for breakfast this morning.


    After eating Chen Xin''s porridge with minced ham, Qin LAN asked Chen Xin, "ah Xin, you said you would start to transform your home today. How do you plan to start? Is there anything I can do for you? "


    "Where to help? There''s no place to help. I''ve finished most of the transformation. The reason why I didn''t finish it before is that I just didn''t have enough materials. " Chen Xin heard that Qin LAN wanted to help, thought about it and declined her kindness: "now the city government has sent materials, I''m enough alone, a LAN, you have a good rest today."


    With that, Chen Xin finished cleaning the table and went to the storeroom alone.


    Qin LAN heard that Chen Xin said that he didn''t need his own help and didn''t ask for it. Instead, he turned on his game console and was ready to have a good rest as Chen Xin said today.


    And Chen Xin came to the storeroom, looking at the materials filled with the storeroom, ready to start the overall upgrade of the shelter.


    Open the system interface, control the thinking, and focus on the whole refuge. The system interface also shows the option to upgrade the whole refuge.


    "Simple shelter"


    "upgrade plan 1: upgrade the shelter protection level, enhance the shelter disaster prevention ability, enhance the survival comfort, the shelter overall technology + 1, upgrade the survival 12000"


    "upgrade plan 2: expand the shelter living space, increase the shelter capacity, improve the shelter material support ability, the shelter can accommodate people Chen Xin did not adjust the same upgrade plan as before, but he had his own detailed ideas on some details of the overall upgrade of the refuge.


    Without too much hesitation, he directly put in all kinds of materials in the storage room and chose two plans to upgrade at the same time. It still takes nearly 3000 points to reduce the survival cost to one tenth, which is two-thirds of the survival cost of Chen''s novice. Most of the materials stored in the storage room are directly consumed, leaving only a little bits and pieces.


    It can be said that Chen Xin''s accumulation over the past six months has been consumed in this upgrade.


    But as the green light spreads to every inch in front of him, Chen Xin closes his eyes with a smile of joy and expectation. He wants to open his eyes and see a new refuge.


    When he opened his eyes again, the green light had gone, and the shelter had changed.


    He is still standing in the storeroom, but this storeroom has become a simple food storeroom, with shelves to store all kinds of food.


    Chen Xin looks at the food storeroom as big as the original storeroom, and checks the refrigerator upgraded from the previous food storeroom and refrigerator. Chen Xin nods and leaves the storeroom with satisfaction.After going out of the storeroom, Chen Xin should face the original public space, but now it has been upgraded into a hall.


    This is one of the changes made after the overall upgrade of the refuge. Chen Xin changed the original refuge into two floors, with the public space as a hall connecting the upper and lower floors.


    The rooms on the first floor are storage room, workroom and infirmary, as well as the power generation area composed of ground source heat pump, algae oxygen generator and power distribution room. The passage connecting the planting greenhouse is also arranged on this floor.


    The main body of the second floor is a semi open living room and kitchen, because the public space runs through the upper and lower floors, so one side of the living room is just a structure similar to the balcony, you can directly see the first floor.


    There are five double rooms around the living room. Each room has a separate bathroom and bath function. However, Chen Xin has built an independent bathroom on the second floor, which can be regarded as fulfilling his promise to Qin LAN and making a hot spring bath.


    Chen Xin didn''t go up to the second floor, although as soon as he looked up, he could see Qin LAN sitting in the living room playing games, as if she didn''t feel anything.


    Turn around and come to the planting greenhouse through the channel connecting the planting greenhouse. There have been earth shaking changes here.


    The original square planting greenhouse has become a huge cylindrical structure with a diameter of 15 meters and a height of 20 meters, and the biggest change is not the space of the planting greenhouse, but its internal planting area.


    The bottom of the greenhouse has become a one meter deep pool, in which several swimming fish are swimming happily. It seems that Chen Xin was too depressed to raise them in the sink before, but now he finally has enough space to swim.


    In addition, the original one layer hydroponic planting plate and soil planting area have also changed into a square hydroponic planting plate with six layers and an area of one hectare, one layer on top of the pool, which is irrigated by the circulation system in the planting greenhouse.


    The bottom two layers of planting plates are planted with upland rice before. It seems that there is no big difference, but the rhizome at the bottom is no longer rooted in the soil, but replaced with planting plate and nutrient tank.


    On the top four are a quarter of carrots, a quarter of cabbages, a quarter of lettuce, and the remaining quarter of strawberries. The other three are vacant.


    These are the crops planted before Chen Xin. Obviously, the system upgrade only changed the structure of the greenhouse and did not affect these crops.


    The whole planting greenhouse has now entered the mechanical automation stage. It is more advanced than Chen Xin''s previous practice of digging and harvesting the ground by himself.


    This is obviously the embodiment of science and technology level + 1 in the overall upgrade.


    After checking the planting greenhouse, Chen Xin came to the power generation area again. As the energy supply core of the whole refuge, this area can be regarded as the heart area. Especially after the upgrade, Chen Xin connected the ventilation system of the refuge here, and the whole power generation area became more important.


    The power generation area is also a large room. On the floor are four ground source heat pumps and their matching generators. Against the wall are four huge green glass cans, which are algae oxygen generators.


    However, after they are upgraded, they not only become larger, but also can be automatically extracted from algal sediments. Even the algae inside have changed to produce ethanol.


    Although the output is not high, it can only provide Chen Xin with 100 liters of ethanol a month, but this is very good news. At least the output of the refuge is a new product.


    The algal oxygen generator is now connected to the air exchange system, and the oxygen produced by the algal oxygen generator will be directly transported to every corner of the refuge through the ventilation pipe.


    As for the power distribution room, it is still a combination of power distribution cabinet and storage battery, but there are three more battery installation positions beside it, which can be used to install the isotope thermoelectric battery used by Chen Xin in armored RV.


    Although Chen Xin himself has made isotope thermoelectric batteries, commonly known as nuclear batteries, he has not directly changed the refuge to use nuclear batteries or nuclear reactors for power supply. Instead, he has prepared three isotope thermoelectric batteries as backup power in the power distribution room.


    "That''s good! In this way, it''s different to worry about power failure and lack of oxygen. " Chen Xin nodded his head with satisfaction, although the problem of lack of oxygen and power failure has long been ignored by him.


    After looking at the power generation area, Chen Xin took another look at the medical room and the working area. There was no big change in the two. The working area only had a more advanced worktable with various kinds of small lathes and equipment, while the medical room separated a sterile operating room and a ward, which looked more like a small medical station than just a medical room.


    These are the main parts of the shelter after the overall upgrade, but Chen Xin knows that in addition to these, the entrance area on the other side of the gate has also changed dramatically. At least he moved the material storage room to the top and turned it into a material warehouse.

 Chapter 209

    Originally, Chen Xin''s connecting passage between the main part of the shelter and the entrance part was a 50 meter long ramp. At that time, it was built to facilitate the cars parked inside the shelter to get in and out of the shelter, but in fact, the use of this corridor was not as convenient as originally expected.


    Because the length is only 50 meters, but the height difference from the entrance to the shelter is nearly 20 meters, which makes the slope very steep. It''s not very convenient to drive in and out, or even to drag materials with a cart.


    But at that time, when building the shelter, Chen Xin only thought about building the shelter a little deeper to avoid possible meteorite impact on the shelter. He wanted to use the soil layer more than 200 meters above the shelter as protection, so he didn''t have to worry about too many details.


    After all, it''s just that the slope is relatively large, so it''s not very convenient to use. It''s not totally unusable.


    However, now that the system can be upgraded, Chen Xin has also adjusted the corridor. The original inclined connection corridor has been changed into two horizontal passages, and the elevator is used in the middle to go up and down.


    This is one of the reasons why Chen Xin had to wait until the materials from the municipal government were delivered before upgrading the whole refuge. The materials for the elevator were collected by the help of the municipal government. Originally, Chen Xin planned to process them by himself.


    After upgrading, the elevator area can stop an ordinary family car. The whole car is a tubular car with a diameter of 7 meters and a height of 3.5 meters. The bottom of the car can rotate. This solves the problem that the car can''t turn around because of the narrow access.


    Take the elevator to the upper floor. After passing through the passage, it is still the original servicing room, but on the other side of the servicing room, there is an additional material storage warehouse.


    This is an adjustment made by Chen Xin due to the inconvenient transportation of materials before. He put the material warehouse on the upper floor where the entrance is, and only the food storage room is kept inside the shelter.


    In this way, the materials can be directly stored after being transported in from the door, and there is no need to transport them down.


    Anyway, for Chen Xin, where the materials are put is almost the same. He only needs to open the system interface to use the materials, and does not need to pick them up in person.


    Through the preparation room, it is still the channel where the crossbow is placed.


    Chen Xin didn''t make any big changes here. After all, it''s just a channel. The attack ability of Heavy Crossbow is enough.


    His only adjustment is the trigger mode of the heavy crossbow, changing it from the original flap mechanism to infrared induction automatic shooting, and setting up a hidden mechanism to hide the whole Heavy Crossbow in the ceiling.


    Anyone who crosses the corridor when the alarm is on will be directly hit by a heavy crossbow with 90 rounds per minute, which is no less powerful than Chen Xin''s heavy machine gun at the gate.


    As for the way to turn on the alarm, Chen Xin set it to turn on from inside and trigger the attack through face recognition.


    That is, every time you come out from the inside, you can turn on the alarm switch to start face recognition. In this case, through face recognition, you can naturally enter the shelter.


    However, if a stranger enters but fails to pass face recognition, the Heavy Crossbow on the ceiling will be activated to enjoy the experience of dodging the heavy crossbow.


    As for going out through the safety channel, Chen Xin didn''t make any changes in the decontamination room, just upgraded the decontamination equipment inside.


    The outside of the decontamination room is still a garage and a space that can be called a foyer or a porch.


    This is an L-shaped space. The short side is connected with the gate and the decontamination room, while the long side is used to park the armored RV after Chen Xin''s magic transformation for an extended garage.


    There''s nothing to say about the garage and the porch. The garage only adds the function of vehicle maintenance and some repair tools, and the porch is just an open space.


    What''s really remarkable is the gate of the sanctuary.


    It''s still the previous lift metal armor door, but Chen Xin changed it from homogeneous armor to multi-layer composite armor this time, and the thickness increased from 30cm to 35cm. Although the thickness only increased by 5cm, the defense performance is equivalent to 120cm thick homogeneous metal armor.


    The original double mounted Markham at the door has also been replaced by a double mounted 12.7mm three barrel Gatling machine gun, which is the same type as Chen Xin''s armored RV. It can still be controlled by computer and aimed by automatic lock.


    Of course, you can still exercise like Chen Xin did yesterday, and experience 3600 turns at a breath, showing great compassion to the world.


    After reviewing the whole shelter, Chen Xin was very satisfied with the overall upgrading effect. In addition to the improvement of the overall pattern and the level of science and technology, even the original gray concrete wall of the shelter was covered with paint, and the metal support frame was added, which made it look clean, tidy, spacious and bright.


    Even the lighting facilities that used to be just light bulbs have been replaced with LED tubes, which softens the light inside the shelter. What''s more, it adds the light control that Chen Xin has always cherished. The lighting can be adjusted with the change of time, so that people inside the shelter can feel the passage of time.As for Chen Xin''s observation room, which was originally set above the gate, has also been adjusted and upgraded this time. It has evolved from a simple tree antenna room to a formal blockhouse. Not only some living facilities have been added inside, but also a double-layer vacuum glass has been added to the observation port to block the entrance of cold air.


    Of course, in order to retain the defensive function of the observation room, the glass of the observation port can be opened to make it return to the shooting hole.


    As for the vent connected to the external wall, Chen Xin did not make any major changes, but added a ventilator and air filter inside the ventilation duct to improve the ventilation efficiency.


    Back inside the shelter, Qin LAN is still sitting on the sofa playing games. Chen Xin''s previous experience seems to have no effect on her. Although her living room has completely changed, the game console has been upgraded from PS4 to ps5, and even the size of the TV has been enlarged a lot.


    "The work is done?" Qin LAN watched Chen Xin pick up another handle on the side to access the game, and also pressed the pause to switch the game out to double mode.


    Chen Xin sat down, nodded and said, "I don''t have much work left. As long as the materials are in place, it can be done quickly. Now it''s all finished."


    "If you''re done, come and play with me. Last time you lost to me, now you have a chance to win me!" Qin LAN looks at Chen Xin and deliberately uses a method to motivate him.


    Chen Xin also a free and easy smile, holding the handle said: "that is I let you!"


    "Ha ha, who let who also perhaps!" Qin LAN is obviously unconvinced and challenges Chen Xin: "how about a bet?"


    "All right, what''s the bet?" Chen Xin gladly responded. Although the ps5 was launched before the disaster, he hasn''t tried the latest model yet: "you can''t default if you lose!"


    Qin LAN bit his lip, thought about it and then made up his mind to say: "the loser is below at night!"


    "Down there? Don''t you sleep in the lower berth? What''s next... " Chen Xin responded, and the expression on his face suddenly became meaningful: "bet so much? Then I''m going to use 12% of my skill! "


    Qin LAN now is full of shame, but still very brave said: "hum! Anyway, I won''t lose. I''ll see how you die! "


    With that, he threw a provocative look at Chen Xin and started the game directly.


    Chen Xin smiles, and is also serious. It''s a matter of man''s dignity. This kind of thing can''t be lost. Even if it''s lost, it''s nothing for Chen Xin to lose.


    It''s not enough to know how to decide between them. Anyway, when Chen Xin woke up the next morning, Qin Lan was lying in his arms.


    After carefully pulling out his arm, Chen Xin gets up from the bed and puts on his clothes. In order to avoid waking Qin LAN, he goes to the bathroom of another room to wash, and then comes to the upgraded new kitchen to prepare breakfast.


    However, Qin LAN didn''t sleep very much. The lack of pillow people around her made her wake up quickly.


    Qin LAN, wrapped in a blanket, comes to the living room and looks at Chen Xin, who is busy in the kitchen. Instead of disturbing him, she leans against the kitchen door.


    The upgraded heating system provides a warm enough environment for the shelter. Even if Qin LAN is wrapped in a blanket, she doesn''t feel cold. Instead, she watches Chen Xin busy with great interest.


    "Get up, why don''t you sleep a little longer?" There are many people at the kitchen door, which naturally can''t hide from Chen Xin. He looks up at Qin LAN and continues to cut the lettuce that has just been scalded with boiling water.


    "I can''t sleep without you." Qin LAN looked at Chen Xin and suddenly said something almost coquettish: "what do you eat in the morning?"


    "You can''t sleep without me?" Chen Xin gave her a smile and looked at her fondly, then said, "I made some lettuce salad and cooked porridge, but I don''t know if you are used to it without salad dressing? Go brush your teeth and you''ll be able to eat in a moment. "


    "Lettuce salad? It''s good to have fresh vegetables now. There''s not so much fussiness. " Qin Lan also laughed, wrapped in a blanket and went to the room: "then I''ll brush my teeth."


    Qin LAN goes to brush her teeth, and Chen Xin''s lettuce salad is also cut. Just use salt and other seasonings to flavor it, and you can serve it on the table.


    When Qin LAN came out of the bathroom and sat down at the table with only a shirt on, the table was already set with chopsticks and steaming porridge.


    "Ah Xin, it''s better for you to have everything here, even breakfast is so comfortable!" While eating breakfast, Qin LAN asked Chen Xin, "I''m going back to the Municipal Bureau today. How about you, ah Xin? What are you going to do today? "


    "I plan to make the ground source heat pump that the municipal government wants. If I finish it early, I can start early." Chen Xin answers Qin Lan''s question and asks her, "do you want me to take you back?"

 Chapter 210

    After the overall upgrade of the refuge, Chen Xin''s worktable has also been upgraded to the + 1 level of science and technology, adding a lot of new processing equipment, not to mention, making the already easy-to-use worktable more convenient.


    Especially after the upgrade, the new drawing recording function of the workbench is a long-awaited function for Chen Xin, which enables him to save a lot of effort.


    For the worktable upgraded from the system, having drawings means that the products can be automatically produced according to the drawings with the help of the processing capacity of the system, instead of Chen Xin''s own processing parts one by one and then assembling them by hand.


    Chen Xin can make use of the system processing function to process the parts and raw materials into the parts required by the drawings, and then assemble them together through the system to produce the finished products, saving a lot of time and energy.


    The only thing he needs to do is to input the drawings into the drawing library of the workbench, which requires him to operate by himself, or draw, or make a device to let the system record the drawings. Of course, he can also input the ready-made drawings through the computer.


    Through his notebook, he input all the drawings stored in the computer to the workbench. Chen Xin also picked up a pencil and spread out the white paper on the workbench to draw the drawings of the ground source heat pump.


    Of course, Chen Xin knows mechanical drawing. He learned this skill when he was in high school. Although he could not draw a complete drawing with a pencil like his father''s, mechanical drawing itself was difficult for him.


    However, I learned CAD drawing after I worked. I haven''t used this skill for a long time. Now I pick up the pencil again, and I''m back in my old business.


    It''s not that Chen Xin can''t use computer CAD to draw drawings, it''s just that his computer is just a notebook. Even when upgrading the refuge, Chen Xin paid special attention to it and enjoyed an upgrade, but it still can''t cover up the essence that it''s just a notebook. He can''t do CAD drawing while transferring big data files.


    This is not something that can be done with an upgrade, and for Chen Xin, there is no need to do so. The time he spent drawing by hand is only a little more than computer drawing.


    After all, it''s just a simple general assembly drawing. Chen Xin doesn''t need to draw every part carefully.


    Hum a little song, hand a few pencils rotation, a pair of not complex ground source heat pump assembly general plan has been drawn out by Chen Xin.


    The drawings are submitted through the system. As the newly drawn drawings on the workbench are swept by a green light, a new drawing has been added to the system interface.


    Seeing that the drawing has been uploaded successfully, Chen Xin quickly points out the drawing and intends to try to see if it can be used to manufacture a ground source heat pump.


    This is also the main purpose of Chen Xin''s drawings. If the drawings can be used for manufacturing, it will only take a few days for the city government to order 50 sets of ground source heat pumps from Chen Xin, and he can start early.


    The system is still as reliable as ever, and has not failed to live up to Chen Xin''s expectations. As he points out the drawings, the manufacturing options of the required materials and parts also appear in front of Chen Xin.


    However, just when Chen Xin was planning to start manufacturing, he suddenly stopped, and an idea came into his mind. Since the items can be upgraded, can the drawings also be upgraded with survival?


    If it can be upgraded, does it mean that it can upgrade the existing drawings and make better equipment?


    With Chen Xin''s idea, new options are also emerging on the system interface.


    Chen Xin can improve the drawings under the current scientific and technological level by consuming survival points.


    "Isn''t it an upgrade?" Looking at the options displayed in the system, Chen Xin was surprised.


    What the system provides is not a drawing upgrade, but a drawing improvement option. Chen Xin, who has been used to the system''s ability to upgrade everything, is really surprised and novel.


    However, after carefully looking at the tips given by the system, he also understood.


    Drawing upgrade can only upgrade the carrier of the "drawing". For example, it can upgrade from paper to other materials. For example, the flexible touch screen e-ink drawings that can be seen in movies can be zoomed in and out, adjusted and modified at will


    However, the contents of the drawings can not be upgraded, they can only be improved.


    Moreover, due to the limitation of the workbench, the improvement of the drawing content can not exceed the technological level of the workbench itself.


    In other words, Chen Xin must improve the drawings within the scope of the current technological level of the workbench.


    This is not a particularly useful function for Chen Xin, but it can not be said that this function is useless.


    At least now, he can make some modifications to the drawings of GSHP to improve the output power of a single GSHP, or transform the existing drawings into larger equipment with higher power.


    At first glance, it seems that there is no difference between the two, both are to improve the power of ground source heat pump, but in fact there is still a big difference.To improve the output power of a single ground source heat pump is to optimize the equipment structure and improve the working efficiency of the equipment without changing the equipment volume and material consumption, so as to improve the output power.


    The upper limit of this optimization is not much, it only belongs to the category of general product upgrading.


    The latter is to concentrate the materials consumed by multiple equipment on one equipment, and to produce large equipment with higher power and larger volume.


    At present, the ground source heat pump Chen Xin is able to manufacture belongs to the small equipment type for family use in terms of specifications and models. There is no problem for a single equipment to meet the small space use of private shelters.


    But for the official shelter, even if it''s just a small shelter, it''s not a small facility that can meet the demand.


    This is also why when the municipal government mentioned to Chen Xin that the ground source heat pump heating pilot should be carried out in a small shelter, Chen Xin would say that a small shelter needs 50 sets of ground source heat pumps.


    Because he does not have the ability to manufacture large-scale equipment with higher power, he can only adopt the way of parallel connection to meet the use needs.


    However, with the improved function of this drawing, Chen Xin can make use of this function to manufacture large-scale ground source heat pump with higher power, which can meet the heating demand of 50 sets of equipment and several sets of equipment.


    Having made up his mind, Chen Xin did not hesitate. He directly used 100 survival points to improve the route of large-scale equipment on the GSHP drawings he just uploaded.


    After the improvement, a large-scale ground source heat pump drawing was added to the system interface.


    However, to Chen Xin''s surprise, in the system interface, the original GSHP drawings did not disappear, but still exist.


    "It seems that the improved drawings will not consume the original drawings!" Chen Xin is a bit fussy, but he doesn''t worry about it. Instead, he looks at the drawings of a large-scale ground source heat pump. He can''t wait to see how much material is needed to produce a large-scale ground source heat pump, and what kind of output power a device has.


    In the system interface, the materials required for a large ground source heat pump equipment have been listed in detail, and the performance of the equipment is also displayed in the form of data list, so that Chen Xin can intuitively compare the differences between large ground source heat pump equipment and small ground source heat pump equipment.


    The output power of Chen Xin''s small ground source heat pump equipment is about 10kW, which needs to consume an ordinary household air conditioner as the material to manufacture.


    Of course, the reason why an ordinary household air conditioner is used as the material unit is that the parts contained in an ordinary household air conditioner are enough to meet the manufacturing needs of a small ground source heat pump equipment.


    However, after the system upgraded the workbench, a series of parts such as compressor, evaporator and condenser have been listed in the list of required materials on the drawing.


    Chen Xin can get parts by dismantling the air-conditioner units sent by the municipal government. He can also directly use the parts as materials for production and manufacturing, and even use the drawings to make his own parts with raw materials.


    This is naturally good news for Chen Xin. In this way, he doesn''t have to worry about that if there is no external air conditioner, he will not be able to produce ground source heat pump.


    Compared with the small ground source heat pump equipment, the output power of the large ground source heat pump equipment is increased to 50KW, and the materials consumed by the equipment are naturally doubled. Only the parts and some raw materials contained in three ordinary household air conditioners can be manufactured.


    Compared with the original consumption of five air-conditioning external units as materials to produce five 10kW small ground source heat pumps, it naturally saves materials, and can also save more installation space.


    Although the volume of large-scale ground source heat pump equipment is much larger than that of small-scale ground source heat pump equipment, it is not as large as one of the top five, which is also a very important consideration for underground shelters with limited underground space.


    Looking at the large-scale ground source heat pump equipment on the drawing, Chen Xin thought about it for a while, and decided to first make three large-scale ground source heat pumps with the materials of ten small-scale ground source heat pumps sent by the municipal government.


    When the leaders of the municipal government came to discuss with Chen Xin about the ground source heat pump, they asked him to manufacture larger ground source heat pump equipment. At that time, Chen Xin explained the past on the ground that the materials could not meet the needs.


    For the municipal government, of course, large-scale equipment is better than small-scale equipment. When Chen Xin was able to manufacture large-scale ground source heat pump equipment, they would only clap their hands and applaud, rather than feel that he had violated the previous agreement.


    So without hesitation, Chen Xin directly started the workbench and began to manufacture the first large-scale ground source heat pump equipment.

 Chapter 211

    Compared with manufacturing ten 10kW small equipment, three 50KW large equipment is obviously stronger in the overall output power.


    Another advantage of large equipment is that although the output power of a large equipment is the same as that of five small equipment, the power consumption of large equipment is obviously lower at the same output power.


    The manufactured equipment did not appear on Chen Xin''s worktable, but directly exported to the upper material warehouse.


    This is undoubtedly one of the new functions after the upgrade. Chen Xin can choose to make the manufactured items appear on the workbench, or he can also choose to put the items directly into the material warehouse, so as to avoid some items occupying the internal space of the main body of the refuge.


    The manufacturing time of three large-scale ground source heat pumps is much shorter than that of ten small-scale ground source heat pumps originally expected by Chen Xin.


    According to Chen Xin''s last time of manufacturing ground source heat pumps for the special police force, he can probably complete three small ground source heat pumps in one day, but now he has finished manufacturing three large ground source heat pumps in about one noon and afternoon.


    This is undoubtedly a major positive for Chen Xin.


    Originally, he needed to manufacture 50 sets of small-scale ground source heat pump equipment. Now he has replaced them with large-scale ground source heat pump equipment. With the same total output power, Chen Xin has completed nearly one-third of the task requirements with one-fifth of the original materials and less than one-fifth of the construction period.


    You know, Chen Xin''s original calculation was that ten small devices could be upgraded in two to three days. Now it took only one day to complete all of them, and there was a little surplus in the materials. For Chen Xin, it saved him a lot of time, and he could start a few days earlier than expected.


    The result was reported to the people contacted by the municipal government through the short wave radio station. Sure enough, after learning the news, the municipal government also showed great joy and interest.


    After all, people in the municipal government can tell which one is easy to maintain and use, ten or three.


    Moreover, Chen Xin is able to manufacture large-scale ground source heat pump equipment, which is also a very significant good news for the city government''s plan to reopen small shelters.


    If it is not for the city government''s original plan to use ground source heat pump heating in a small shelter as a pilot, and then decide whether to use more small shelters according to the effect, the leaders in charge of this matter are going to ask Chen Xin to order more equipment, so as to reopen all the small shelters that were sealed up in the urban area.


    But after all, it''s the leader. He doesn''t have such an impulse to do things. Besides, Chen Xin also says that he needs to go back to his hometown to pick up his parents. It''s not easy for people in the city government to change their plans and force Chen Xin to stay.


    Therefore, the leader of the municipal government in charge of this matter just asked people to send the manufacturing materials discussed before to Chen Xin''s refuge, and at the same time, three large-scale ground source heat pump equipment were received and sent to the small refuge to be opened.


    As for the installation of ground source heat pump, Chen Xin or the leaders don''t need to worry about it. Naturally, there is a municipal construction team to deal with this kind of thing. Chen Xin only needs to be responsible for providing equipment, while the leaders only care about the results.


    As things go smoothly, Chen Xin naturally doesn''t worry about it any more. Next, he just needs to use the materials provided by them to complete the production of ground source heat pump according to the requirements of the municipal government.


    In addition, what Chen Xin needs to worry about is how to transfer his refuge to Mo Qingyan and Mo Qingxin before he leaves.


    Chen Xin has negotiated with Mo Qingyan about this matter, and she has agreed to come back to take care of Chen Xin''s shelter, but for the time being, she and Mo Qingxin have not moved here.


    However, Mo Qingyan also agreed that she would move in two days before Chen Xin''s departure, so as to set aside enough time to get familiar with Chen Xin''s refuge, so that she would not use the equipment in his refuge after Chen Xin left, causing any unnecessary trouble.


    In addition to these things, Chen''s vegetables in the greenhouse are about to be harvested, which means that the monthly material exchange with the SWAT team is approaching.


    It''s just that the materials from the special police team had been sent to him by the city government before, but the vegetables from Chen Xin''s side had not yet reached the harvest time, so this material exchange was just Chen Xin''s unilateral delivery of the harvested vegetables to the special police team.


    And this kind of thing because Chen Xin had advanced the exchange share of the next two months, and he had to do it twice before he could exchange materials again.


    According to Chen Xin''s own estimate of time, if everything goes well, by that time he will have picked up his parents from his hometown.


    So after thinking about it for a while, Chen Xin decided that Mo Qingyan would be in charge of this material exchange and the next two material exchanges, while he could leave a few days in advance and go back to his hometown early.


    Fortunately, now his greenhouse has been fully mechanized, and both sowing and harvesting can be done by machines. Mo Qingyan only needs to operate on the console, and she doesn''t really need to do farm work like Chen Xin did before.While thinking about these things, Chen Xin also came to the planting greenhouse, came to the console, and checked the growth of crops in the greenhouse through the monitor screen.


    After the upgrade of the greenhouse, the console is a very convenient tool. Through the monitor screen on the console, Chen Xin can see the growth of each crop on the six layers of hydroponic cultivation tray above his head, without climbing up for visual inspection.


    Examining the crops that are about to mature, Chen Xin suddenly noticed that on one layer of hydroponic cultivation plate, there is a small piece of crops that is different from other crops. It looks like a pile of weeds.


    Chen Xin drew the camera closer, and then he realized that this was the herb he had promised to plant for Dr. Hongrui.


    Chen Xin planted them before and took care of them later. However, it is obvious that so many things happened during this period that Chen Xin himself has forgotten that he also planted these herbs.


    The growth of these herbs is quite good, but as medicinal materials, they don''t grow as fast as the vegetables on the side. It will take some time to cultivate them before they can be picked.


    After checking these herbs, Chen Xin didn''t care too much. The herbs are growing well at present, and it''s still early to pick them, so he didn''t care too much.


    Just looking at these herbs, he thought of something he had ignored.


    That is, although he prepared a first-aid kit on the armored RV, he did not prepare enough medicine.


    It''s not that Chen Xin forgot to prepare the medicine. Before, he took all kinds of medicine from the medical room and put it in the medicine box of the armored RV.


    Not only medicine, but also a simple operation bag that can be used for emergency operation. Chen Xin has prepared two to avoid accidents on the road.


    However, these drugs were prepared before the disaster, and the types were limited to some common drugs. In addition, Chen Xin had to leave some of them in the shelter, so although it was not enough, it might not be enough in case of some accidents.


    "It seems that we have to find a way to get some medicine!" Chen Xinmo rubbed his chin, seriously thinking about what medicine he would like to prepare: "unfortunately, something happened at the doctor''s home, otherwise he would be a good place to change his dressing. Now he is on Bruce Lee''s side, I can''t find him to change his dressing."


    It''s not that Chen Xin thinks there''s something wrong with going to Li Yulong''s place to change the medicine. Instead, he goes to the doctor to change the medicine, which is bound to let Li Yulong know about it. If Li Yulong knows about it, I''m afraid the medicine will not be changed because of his personality.


    Although Li Yulong asked Chen Xin for help, Chen Xin did help him, but on the whole, Chen Xin still owes Li Yulong the favor. Even if he wants to collect wool, he can''t always collect it on Li Yulong alone.


    What''s more, it''s not easy to repay the debt of human relations. When there are many such things, they will affect the relationship between Chen Xin and Li Yulong.


    So there''s no need. Chen Xin prefers to go to the hospital through the municipal government to exchange some drugs for use on the road.


    And there is also an advantage to this, that is, the doctors in the hospital are obviously more professional, and the prepared drugs are more able to cope with various situations.


    Now that we have thought of the lack of preparation, we should make up for it immediately.


    Chen Xin didn''t delay. When the staff of the municipal government came to deliver the second batch of materials and towed away the three large ground source heat pump equipment, Chen Xin also mentioned that he needed a batch of drugs with the person in charge of delivering the materials.


    This person in charge is to replace Secretary Li, who is mainly responsible for the handover of materials and equipment with Chen Xin.


    After listening to Chen Xin''s request, he agreed to help Chen Xin contact the hospital and ask the hospital to prepare a batch of drugs for him. He even took the initiative to invite Chen Xin to go back to the city with him and go directly to the hospital to get the drugs.


    Naturally, after completing the handover of materials and equipment, Chen Xin and the person in charge went back to the city in the municipal government''s car.


    When he came to the hospital, the person in charge went to the people in the hospital to help Chen Xin mix drugs, while Chen Xin was bored and sat in the hall of the hospital waiting.


    There is still no big difference between the hall of the hospital and before. Although it is the end of the world, it is also a hospital transformed from a refuge, but there is also an endless stream of patients as before the disaster.


    But Chen Xin can''t take out his mobile phone to play games as before. He can only sit idly watching "cat and mouse" on the TV in the hall.


    Just when Chen Xin felt bored and was about to yawn, a cry full of surprise came from behind: "little Chen Xuedi?"


    Chen Xin was also a little surprised. In his impression, only one person would call him that name.


    As he looked back, he stood up from his chair. The man who appeared in front of him was the one who would call him like this: "Xuejie?"

 Chapter 212

    "Xuejie, why are you here?" Chen Xin was surprised to see the person who appeared in front of him. He never imagined that he would see his sister ten years after graduation.


    "I''m on a business trip here, little Chen Xuedi. This is Oh, I remember. You are from home. You brought lotus seeds to the club activities It seems that Xuejie is also very surprised to meet Chen Xin here. While greeting him, she also looks at the old classmate whom she has not seen for ten years.


    Because it''s going out, Chen Xin is wearing his own protective suit. Although he took off his face protective mask indoors, it seems that he can see at a glance that this is an excellent protective suit, and it''s not a type that can be easily bought.


    Compared with the ordinary warm clothes on other people around, Chen Xin''s dress is obviously a little bit of a standout effect.


    What''s more, I haven''t seen her for many years. The memory of Chen Xin in her mind still stays in the past student days. Chen Xin at that time was not as calm as he is now and had the temperament accumulated over the years. She was full of spirit, confidence and green. That''s Chen Xin in her memory.


    But I haven''t seen Chen Xin for many years. Today, Chen Xin is no longer the green boy at the beginning, nor is she the gentle girl in Chen Xin''s memory with long hair and always a light colored skirt.


    Looking at the student sister with short hair and a black winter coat, Chen Xin said with some emotion: "it''s a long time no see. Since you graduated, you and I haven''t seen each other for ten years, have you?"


    "It''s been more than ten years since I graduated." As she looked at Chen Xin, she also sighed: "it''s been ten years in a blink of an eye! How are you doing now


    "It''s OK. Now in this world, no one can say that he''s living well, just barely alive." Chen Xin shook his head slightly, did not say too much on this topic: "how about you, Xuejie? I remember when you graduated, it seems that you went to take the exam, right


    Xuejie nodded and showed Chen Xin her national emblem pinned on her collar: "Provincial Commission for Discipline Inspection, it''s OK. This time there was such a big event in your city, I was also sent by the province to investigate some things. "


    The elder sister did not elaborate on what she came to investigate. These are confidential matters. However, it is self-evident that people from the provincial Commission for Discipline Inspection appeared in the city before such a big thing happened. What they came to do.


    So Xuejie said that she came to check things, which is not a leak.


    The name of the Commission for discipline inspection made Chen Xin feel awe struck, but he was dumbfounded. Even if the elder martial sister came to kill the treacherous officials with Shangfang''s sword, what does it have to do with the ordinary people like him?


    If it is true, he should clap his hands and say "master Qingtian".


    Thinking of this, Chen Xin couldn''t help laughing: "this is the choice you will make. When I heard that you would go to kaogong, I thought you would go to other units!"


    "My family wanted me to go to the tax bureau, but I still chose my present job to realize my original ideal." Speaking of this, Xuejie also asked Chen Xin curiously, "how about you, Xiaochen Xuedi? I remember when you said that you wanted to "write about the spring and Autumn period, and make up for the injustice in the world."


    Chen Xin''s face is a bit embarrassed when she is told about her ideal of being a secondary school student. Maybe she didn''t feel that she was a secondary school student at the beginning, but now she is 30 years old. Looking back at her original self, she will still feel some shame.


    However, he pretended to be helpless and replied to his sister: "I later chose to write online novels, which can be regarded as realizing the first half of my ideal. It''s just a matter of injustice in the world. Even if I want to write, I can''t send it out!"


    When Chen Xin said this, she couldn''t help laughing: "when I was a student, I felt that I should set up my heart for heaven and earth, set up my life for the living people, carry on my unique studies, and make peace for all the world. But when I really did it, I found that things were far more difficult than my ideal.


    It''s easy to know but difficult to do. It''s not easy for you to do what you want to do. We are all changed by time... "


    Xuejie wanted to say something more. The person in charge of helping Chen Xin prepare the medicine had already got the medicine and came back.


    Seeing Chen Xin''s elder sister, she was surprised and said to her, "team leader Tang, why are you here? Do you know Comrade Chen? "


    "This is my younger brother when I was in college. At the beginning, we formed a club together." Xuejie briefly mentioned the relationship between herself and Chen Xin, but it seemed to avoid any unnecessary trouble for Chen Xin. She still stressed: "unfortunately, we haven''t been in touch with each other since we graduated from university. I didn''t expect that we would see Xuedi again after more than ten years."


    "Is Comrade Xiao Chen the younger brother of group leader Tang? What a surprise When the person in charge heard what the elder sister said, he suddenly looked at Chen Xin in a different way, and his tone was kind: "by the way, Comrade Chen, this is the medicine you want. It''s all ready for you. There are mainly some medicines to prevent common diseases caused by frostbite and low temperature, and some commonly used medicines. I hope they can help you. ""Thank you very much. With these medicines, I feel much more at ease." Chen Xin took the medicine box from the person in charge and said thank you to the other party.


    "Xiaochen Xuedi, you are..." Looking at the medicine box on Chen''s novice, the elder sister could not help showing some concern. It was obvious that such a large medicine box was not commonly used.


    "I''m going to Anhui Province. That''s my hometown. My parents were stranded there before the disaster. I''m going to pick them up now." Chen Xin explained a sentence to Xuejie.


    However, Chen Xin''s explanation surprised Xuejie very much. She couldn''t help staring at Chen Xin and asked, "Xiaochen Xuedi, do you really want to go to Anhui Province? How do you get there? Now in this environment, airplanes can''t fly and railways are not open to civilian use. How can you get there? "


    "Drive your own car." Chen Xin was not surprised by her surprise, but showed her the medicine box in his hand: "that''s why he needs to prepare more medicine for road use. If there is something on the way, he can also have a way to deal with it."


    When she heard Chen Xin say this, she was speechless. She didn''t expect to reunite with Chen Xin ten years later, and he was going to do something that seemed to her almost impossible.


    "Is your car ready? If you drive by yourself, the civil car will freeze out in one night. You can''t drive out at all! " Xuejie still thinks that Chen Xin''s idea is too unrealistic and wants to dissuade Chen Xin.


    The low temperature of tens of degrees below zero is a very harsh environment for the car. Although it is not impossible to drive, it can only be done when the engine is still running. If the engine stops running, the low temperature will not only freeze the car quickly, but also freeze the equipment and parts that are not resistant to low temperature.


    Chen Xin had been prepared for this problem for a long time. She said with a smile, "you don''t have to worry about this student. When did you see me and do something without being prepared? I''ve got a RV ready, and I''ve made some modifications to deal with the environment. "


    "That''s true, little Chen Xuedi. You used to be very safe, but I was too nervous." Xuejie shakes her head. She is amused at her unexplained nervousness. She gives up her idea of persuading Chen Xin and reaches out her hand to him: "then Xuejie can only wish Xiaochen Xuedi a good journey! When you come back, if you are free, you can come to Xingcheng to find me. It''s easy to find out. "


    "Xie Xuejie, Jiyan, I''ll leave first. I''ll visit Xuejie when I come back." With a smile, Chen Xinchong turned to leave with the medicine box.


    However, before Chen Xin got far away, the person in charge quickly called him and helped him arrange a car to take him back.


    When Chen Xin returns to his shelter, he arranges the medicine box and transfers the medicine to the armored RV.


    But while sorting out the medicine he brought back, Chen Xin can''t help sighing that he was able to see her again.


    Although she called her Xuejie, she was only half a year older than Chen Xin, and they were students of the same level. However, after getting acquainted with each other, she asked Chen Xin to call her Xuejie all the time on the pretext of being older, and she also called Chen Xin Xiaochen Xuedi all the time.


    At that time, although she was very gentle in appearance, she had a strong personality. She joined the student union in her first year of enrollment, and formed a club with Chen Xin. She was a great figure in the school.


    Chen Xin remembers that in the second year of the University, she ran for a student union cadre. She became the vice president of the student union. In order to solve the problem of food quality in the canteen, she organized students to write a letter to the University, asking to improve the quality of food in the canteen


    In the two years when she was vice president of the student union, she did a lot of such things. With these things, she became president of the student union in the last year of her senior year.


    However, at that time, everyone was about to graduate, and they didn''t have much energy and time to spend on the work of the student union. In addition, they had to practice. On the contrary, Chen Xin didn''t feel much about the chairman of the student union of the elder sister. She had more impression of the things she did when she was the vice chairman of the student union.


    After graduation, Xuejie went to take an examination of the public. Naturally, she was admitted to the public office successfully because of her ability. However, Chen Xin found an ordinary job and only after many experiences did she choose to be an Internet writer. As a result, they broke up contact.


    Now looking back on the campus life at that time, it seems that the elder sister occupied a considerable part of Chen Xin''s whole university memory, as if his whole university life was almost spent with the elder sister.


    Although they were different in men and women, and they were not even classmates of the same major, Chen Xin and his elder sister were inseparable friends.


    Just ten years later, the once inseparable good friend has become a stranger. It''s like Chen Xin can''t remember the name of this student sister. He only remembers that he called her "Tangtang" in addition to calling her "Xuejie".

 Chapter 213

    "The greenhouse is fully automated. Longniang, you can harvest mature vegetables and replant them automatically every time you go through the console and follow the system prompts above. You don''t need to do it yourself." In the greenhouse, Chen Xin introduced her own greenhouse to Mo Qingyan, and also taught her how to take care of the greenhouse: "I put the seeds in the storage cabinet next to me. When I need to replant, I just follow the system prompts. As long as you follow the steps, it won''t be difficult."


    "It''s all a fool''s operation. If I still find it difficult, then I''m disabled." Mo Qingyan looks at the automatic and mechanized greenhouse in front of her eyes, and her eyes are full of wonder.


    Although she knew that Chen Xin had strong hands-on ability, she did not expect that Chen Xin could build such a highly automated greenhouse.


    Of course, this kind of greenhouse is not without it, but it''s all the laboratories of some agricultural universities, which are specially used to cultivate new crops or research new agricultural technologies. For the first time, Mo Qingyan has adopted fully automatic mechanization to plant ordinary crops just to save her troubles.


    But it also saved her a lot of things. When she promised Chen Xin to help him take care of the greenhouse, she thought she wanted to cultivate the land by herself. Unexpectedly, she just had to press the button and press the prompt to operate the joystick.


    At the same time, Mo Qingyan assured Chen Xin: "don''t worry about the ingredients. You are so advanced and automated. I will take good care of your greenhouse."


    "It''s up to you. Just a few days later, these vegetables can be harvested. At that time, you can harvest all the vegetables, leave some for yourself and Xin Xiaomei, and then give the rest to the people of the special police force." Chen Xin heard Mo Qingyan say so, and naturally she was very relieved. At the same time, he also told her: "they will come to exchange every month Materials, but in the last three months, because I have advanced materials, you just need to give them the crops you produce. "


    "Come on, I don''t know the special police. I won''t miss you." Mo Qingyan nodded. Although she said she didn''t care about it, she wrote it down in her heart.


    Chen Xinjian has explained all the things that should be explained. Then he takes Mo Qingyan out of the greenhouse. In the hall on the first floor of the shelter, Mo Qingxin is dragging her luggage to the room on the second floor. Qin LAN and Ding Ning are helping her.


    "Sister, do you want to sleep in the upper berth or the lower berth?" Lying on the railing of the living room, Mo Qingxin pokes her head out and asks Mo Qingyan.


    "There are so many rooms. What''s the point? Are we allowed to occupy only one room? If you want to sleep up and down, I won''t sleep with you Mo Qingyan felt a little embarrassed when she saw how her sister called, so she said something to her.


    Mo Qingyan said so, Mo Qingxin quickly retracted his head, but did not put his sister''s words in mind, dragging luggage to find a room to live in.


    "Ah Xin, are you ready to start now?" Qin LAN looks at Chen Xin, has explained everything clearly, some do not give up looking at Chen Xin.


    "Well, I''ll leave after lunch. I''ve explained everything that needs to be explained and prepared. There won''t be any problem." Chen Xin naturally understands Qin Lan''s worries and concerns about him, but he doesn''t say anything comforting at this time, just smiles at her.


    In front of Mo Qingyan''s face, Qin LAN is not good at being too close to Chen Xin, so she can only nod her head and say with concern: "then you must pay attention to safety on the road. The radio is on at any time, so we can contact you."


    "I will. Don''t worry too much. You''ve seen my car. I''ll be fine." Maybe he doesn''t want Qin LAN to be too sad. Chen Xin tries his best to be indifferent.


    Looking at him like this, Qin LAN bit his lip a little bit reluctantly, but still didn''t make a special expression, just said to Chen Xin: "I''ll make the lunch for you."


    "Well, if you want to." This kind of thing is inevitable.


    insert the key into the key hole under the steering wheel, start the car, and watch the console in front of him light up. Chen Xin puts his right hand on the touch screen and looks at the camera hidden above the driver''s seat.


    "Face recognition passed, fingerprint recognition passed, the system is starting up." With Chen Xin''s action, the voice of the operating system sounded in the car: "the system is self checking, please wait a moment."


    "The power system is normal, the energy output is 100%; the water circulation system is normal, the water storage in the water tank is 100%; the radar system is normal, the environment is scanning; the communication system is normal, the radio station is in standby, and the UAV is in standby; the life support system is normal, and all data are normal..."


    "The self-test of the system has passed, the car is in good condition, waiting for hit."


    "Engine warm up, ready to go." Chen Xin said the instructions directly in his voice, then opened a side window and waved to the four women who came to see him out: "long Niang, open the door, I''m going!""Be careful on the way!" Mo Qingyan is not sentimental. She just waves at Chen Xin and opens the shelter door.


    Looking at the dark outside the open door, Chen Xin took a deep breath, waved to Mo Qingyan and Qin LAN, and then closed the window: "first gear, move forward!"


    With Chen Xin''s instructions, the engine started to run, and the track under the body began to move forward slowly under the drive of the transmission mechanism.


    Assisted by the operating system, Chen Xin grasped the steering wheel and steered the armored RV out of the shelter.


    Outside the shelter, the wind and snow were still raging, and the roaring wind instantly covered the glass of the cab with a layer of snow.


    He turned on the wiper and wiped off the snowflakes in front of him. Although it was still dark and his field of vision was almost zero, he could only see the light in front of him. Chen Xin habitually did so.


    Through the rear-view mirror beside the front of the car, Chen Xin could see four women standing at the gate of the shelter looking at him. However, he didn''t say anything. He just honked the horn, pushed the control lever, stepped on the accelerator, increased the speed, drove into the dark and embarked on the journey.


    The shelter behind him is getting farther and farther away, and the figure is no longer visible. Chen Xin said to the operating system, "start the terrain display, compare the map, and start positioning and navigation."


    "In the process of generating environment terrain display, the navigation map has been loaded, the intelligent comparison is completed, and the positioning navigation is in progress."


    With the prompt sound of the operating system, a 3D three-dimensional map is projected on the bridge. This is the surrounding environment scanned by the onboard radar. After the processing of the operating system, the map is formed. It not only has the red dot symbolizing the car, but also has a plane map and a marked line.


    The plane map comes from the map stored in Chen Xin''s previous navigator on the SUV. Although the terrain has changed greatly and the satellite positioning signal in the sky has been cut off, the map can still be used as a reference.


    Through the compass to calculate the latitude and longitude, and then according to the latitude and longitude to deduce their own position on the map, although this map is not suitable for the current environment, it can still help Chen Xin determine the direction and his way forward.


    "Release the reconnaissance UAV, switch to automatic navigation driving and maintain cruise speed." Chen Xin saw that he was driving in the right direction, and again issued new instructions with his voice.


    "The reconnaissance UAV has been released, the automatic navigation is switching, the driving authority has been received, and the console is locked." Under the prompt sound of the operating system, Chen Xin released the steering wheel he held, and then the car did not lose control. The steering wheel just shrank back, and then it was locked by the operating system, and the whole car entered the automatic driving mode.


    Autonomous driving is not a particularly new technology. It was invented several years ago, but it has not been put into practice.


    Since Chen Xin wants to transform his car, of course he will not miss this technology. He has already equipped his car with an intelligent system capable of speech recognition and added automatic driving function.


    After all, Chen Xin has only one person. If he is driving on the road and suddenly wants to go to the toilet, he can turn on the automatic driving function, go to the toilet by himself, and let the operating system drive automatically.


    Or like now, although people are still in the cab, the car is moving forward automatically.


    As for the UAV just released, it is used to detect the surrounding environment or detect whether there is hidden danger. Although the radar can scan the surrounding terrain, it may not be able to scan everything, so it is necessary to release the UAV.


    Chen Xin''s car is equipped with four UAVs, two of which are equipped with machine guns, and the other two are equipped with high-resolution infrared night vision cameras, which are mainly used to identify the possible heat sources in the surrounding environment and determine whether they are dangerous targets.


    With these heavy protections and a layer of composite armor wrapped around the car body, Chen Xin dared to go on the road alone instead of taking other measures.


    Although the operating system is driving, Chen Xin is not idle. Instead, he slides the map with his hand to confirm his way forward.


    In fact, before the disaster, there were three routes to choose from from Hunan Province to Anhui Province. The first route was to cross the Yangtze River from the city through the three towns of Hubei Province to Anhui Province. The second route was to go south to Jiangxi Province, cross the Yangtze River through Xunyang, and then enter Anhui Province. As for the third route, it was to go along the border of Hubei and Jiangxi Province, cross the Yangtze River through Huangshi, and cross between the two provinces to enter Anhui Province.


    Each of the three roads has its own advantages and disadvantages. The third road is the shortest and the latest one, while the three towns are the farthest. But this road is very old. Even if you don''t take high-speed roads, you can take provincial or national roads, so you won''t be stuck on the road because of road problems.


    Chen Xin''s choice is to take the road of three towns. After all, he wants to cross the Yangtze River, so it''s safer to take three towns.

 Chapter 214

    Although the crawler chassis has many advantages and is more suitable for moving forward in the snow, the biggest problem of the crawler compared with the wheel is that the speed of moving forward is not fast enough.


    In addition, the car itself is heavy enough, and the maximum speed it can run is only 80 km / h. even if Chen Xin overloads the engine, he can only run to 160 with twice the power.


    The overload mode is used in an emergency. Chen Xin can''t open it easily, and after the overload mode is opened, it will cause a huge loss to the track, engine, transmission device and even the car body itself, which can''t last long.


    Moreover, the theoretical maximum speed at that time could only be reached by running in a straight line on a flat and barrier free road. With the current complex road conditions and poor sight, Chen Xin''s current speed is only 15 kilometers per hour, which is only the speed of the car, not the speed he travels on the map.


    After all, in this kind of environment, the original roads are buried under more than one meter of snow, and the surrounding environment has long been beyond recognition. Chen Xin can''t follow the original road at all. He can only determine his position by comparing the map while waiting for the UAV and radar to scan the surrounding road information, and then decide how to move forward.


    Sometimes the straight line is only 100 meters, but because there is a big crater in the middle of the road, if you want to go around it, you have to walk several hundred meters more, which naturally takes a lot of time.


    So it seems like a speed of 15 kilometers per hour. In fact, it''s hard to advance 10 kilometers an hour on the map.


    "Is there another crater? What''s the number one I''ve come across today? " Chen Xin couldn''t help complaining that through radar and UAV scanning, there was another crater with a diameter of more than 50 meters on the road ahead, forcing him to make a detour.


    Although the track''s off-road performance is good, and it''s not impossible to drive straight down to climb the pit, Chen Xin still doesn''t want to climb the pit if there is a flat road.


    This section of the road, Chen Xin has not let the operating system to drive automatically, but holding the steering wheel, carefully forward.


    Automatic driving is easy, but the intelligence level of the operating system Chen Xin installed on the car is not high enough. For road condition identification and route planning, only the car can pass through. So yesterday, when Chen Xin let it drive automatically, he rushed into the crater on the road several times.


    Although relying on the climbing performance of the vehicle itself, these craters can not hinder Chen Xin''s progress after they are covered with snow, for Chen Xin sitting in the car, the bumps caused by the vehicle climbing the crater are too uncomfortable.


    If he can, he is willing to make a little more detour and go as flat as possible.


    However, when it comes to craters, I don''t think that although there are houses destroyed by meteorites in the urban area, craters are not very common.


    However, after he came out, Chen Xin found that there were quite a lot of craters on the road. On average, he could walk for about an hour or two and meet one.


    Most of these craters are tens of meters to hundreds of meters in diameter, most of which are formed by falling debris.


    At the beginning, in order to prevent the meteorite from falling into the blue star, Lucia guided the nuclear bomb launched by the 5S to bombard the meteorite. Although it did not completely smash the meteorite, it also blew down a lot of debris.


    Instead of falling directly to the surface of the blue star, the debris temporarily floated in low earth orbit, just like the space debris around the blue star.


    Some of them will gradually fall to the earth''s surface over time, and some will always float in low earth orbit. Most of the debris that fall on the surface of the blue star will burn up in the sky after burning in the atmosphere.


    Even if the debris that can fall to the surface is not large, the crater caused by the fall is only a "small crater" of tens to hundreds of meters.


    In fact, since the meteorite impact on the blue star, the dust formed by the meteorite impact in the sky has been falling continuously for more than half a year now. Although it is still dark and the sunlight can''t penetrate, as time goes on, the dust is falling more and more, and the sunlight will eventually penetrate the clouds.


    But this time may be very long. In a short period of time, the inland watch can only recover to the low light level environment, rather than the current dark environment.


    If the earth''s surface can be restored to a low light level environment, then the living conditions of human beings should be improved, right?


    Chen Xin took control of the steering wheel, bypassed the crater, and then switched to automatic driving mode again, which he thought about himself.


    Sunshine is very important for human beings and life on the earth. It can be said that life only comes with sunshine.


    Compared with cold, lack of sunshine is the biggest problem. After all, in the past, the temperature on blue star was not as low as minus 60 or 70 degrees in winter. However, even in cold Siberia, there are dense forests, so cold will not cause the extinction of life.


    But without sunlight, most life would not survive.


    So if the earth''s surface can recover to a low light level, Chen Xin believes that even if the earth''s surface is covered with dozens of degrees below zero temperature and ice and snow, there will still be traces of life slowly recovering.But the process of recovery will be very long, long enough to use a hundred years as a unit of calculation.


    In the history of blue star, it is not uncommon for the whole ecosystem to be destroyed and the species to be almost completely destroyed. Even now, the global temperature drops to tens of degrees below zero. This extremely cold climate stage is called the ice age by scientists.


    There have been two of the most famous ice ages on the blue star.


    One occurred in the Pleistocene, about one million years ago, when human beings had just begun to evolve, because the orbit of the blue star around the sun changed, and the continental margin along the coast of the North Atlantic was covered with thick ice.


    Another is that about 21000 years ago, most parts of North America and Europe were covered with ice as thick as 2km, which caused the sea level to drop by as much as 120m. The most brutal ice age in 500 million years affected at least 30% of the surface of Bluestar.


    However, neither of these two glaciations is more dramatic and cruel than the global glacial events between 800 million and 550 million years.


    Between 800 million and 550 million years ago, ice formed on the surface of the blue star from the poles to the equator. Only a small amount of liquid water remained on the bottom of the sea. At that time, the whole blue star was completely frozen, which was nicknamed "snowball Blue Star" by scientists.


    As for the reasons for the formation of "snowball Blue Star", there are many reasons, such as the sun is blocked, the ice chamber gas is produced in large quantities, or the ice sheet reflects the sun.


    However, no matter what the origin of the "snowball Blue Star" is, the surface of the blue star at that time was all covered by thick ice, only the ice layer in the equatorial region was a little thinner, maybe only a few meters thick.


    So for the blue star itself, extremely cold climate is not a problem, for life, it does not make it completely extinct.


    But for humans and other creatures living on the surface of the blue star, it is a natural disaster that can make everything extinct.


    Nowadays, the surface of blue stars is rapidly cooled because of the sun''s shielding. In addition, a lot of surface water has been evaporated by meteorite impact before. Under the influence of both phases, the surface has been covered by ice and snow, which is very similar to the environment of blue stars in the "snowball Blue Star" period.


    In such a cold environment, even the ocean has to be frozen, and the whole planet has been frozen into a snowball before the dust dissipates and the sun shines on the surface of the blue star again.


    That is to say, even if the normal light is restored, the temperature is still very difficult to rise under the reflection of ice and snow on the surface. The extremely cold weather may last for a long time, and this is very long, based on the blue star itself.


    "It''s really unpleasant!" Although it is no different for Chen Xin whether the extremely cold winter lasts for one hundred years or one million years, it is still a reality that it is difficult for people to have a good mood.


    The long night may pass quickly, but the cold will not.


    Maybe it will be a long time before human beings want to see spring flowers bloom again.


    Maybe human beings can relive the old days by building greenhouses, but it will be a very long wait to see green mountains, green waters, blue sky and white clouds again.


    However, such a thing, even if we think deeply, should be the work of scientists, but it has no significance for Chen Xin himself.


    Maybe in the future, with the help of the power of the system, he can create a planet reformer to transform the planet''s environment, so that the ice and snow of the blue star will melt ahead of time, the environment will return to before the disaster, and even directly transform the blue star into Gaia, but this is the future.


    For Chen Xin now, it''s more practical to think about where to rest at night.


    Looking at the map on the console and the records on the display screen, Chen Xin''s driving mileage today is about 150 kilometers, but the straight-line moving distance on the map is less than 40 kilometers, so it can be said that he has not gone far.


    The main reason why Chen Xin only walked a straight distance of more than 40 kilometers was that he had to turn back a long way to get off the highway and bypass the damaged section because of the damage to the viaduct on the highway.


    This detour has undoubtedly delayed him a lot of time. If there is no detour, according to Chen Xin''s estimation, he should walk 10 kilometers more in a straight line today.


    However, in Chen Xin''s view, he is not afraid of being slow, but of being unable to walk.


    As long as we can move forward and walk slowly, we will arrive. But if the road ahead is blocked, that is the most troublesome thing.


    After driving the car to a windy hollow, parking and putting down the eight hoes at the bottom of the car, Chen Xin left the cab and went to the life cabin to make dinner for himself.

 Chapter 215

    "Diddiddidi, diddiddidi..." When the alarm bell rang, Chen Xin opened his eyes and got up from the bed.


    Brushing his teeth, washing his face, and the wet and dry toilet in the car allow Chen Xin to even take a shower. But without this demand in the morning, he didn''t go into the bathroom.


    After finishing his personal hygiene, Chen Xin came to the Liuli table and smashed the two energy bars attached to the shelter food into a cup. After adding a little salt and sugar, he boiled them with hot water to serve as his breakfast.


    Eating this semi liquid breakfast, Chen Xinxin tasted the semi salty but not sweet taste of the energy bar in the cup. He couldn''t help muttering: "less sugar, it seems that we can grow some coffee beans and beets in the future."


    While muttering about this, Chen Xin came to the cab and put the cup in his hand into the cup holder on the console. At the same time, he opened the map projection on the console and thought about how to go today.


    Chen Xinjia''s city is the north gate of Hunan Province. To leave the administrative scope of this city is to leave Hunan Province and enter the boundary of Hubei Province.


    Chen Xin is very familiar with this section of the road. After all, in the past, his parents would bring him to this hot spring every year.


    Moreover, Hubei Province, a city adjacent to Hunan Province, is also very famous in history. The "Three Kingdoms zhoulang Chibi" mentioned in Su Shi''s famous poem "niannujiao ¡¤ Chibi nostalgia" is located in this city.


    Speaking of the famous battle of Chibi, it has something to do with the city as well as the city where Chen Xinjia is located.


    After all, Yueyang Tower, which is also well-known throughout the ages, was originally used by Lu Su of the eastern Wu Dynasty to train the water army. In the battle of Chibi, the Sanjiangkou, where Cao Jun fought with the Allied forces of the eastern Wu Dynasty, was the entrance of Dongting Lake into the Yangtze River, where Jingjiang River, Yuanjiang River and Xiangjiang River met.


    It can be said that the battle of Chibi had a deep relationship with these two cities.


    However, as Su Shi said in his poem, "when the river goes to the East, the waves are washed away, and the heroes of the past have been washed away for more than 2000 years. Now, even the traces engraved on the rocks have been covered by ice and snow.


    I don''t know if anyone will remember a legendary war under the ice and snow in another 100 years?


    Chen Xin had such an idea in his mind, but he didn''t rely on the idea of hanging on to the ancient battlefield. His planned route was to pass through the urban area of Chibi, not to reach the ancient battlefield by the Yangtze River.


    On Chen Xin''s way forward, he will pass by a hot spring resort, which makes him interested. At the same time, he has some nostalgia. After all, his parents brought him to the hot spring resort.


    Just along the way, Chen Xin didn''t change his direction. He finished his breakfast in the cup, sent the cup to the counter to wash, and poured himself a cup of hot water. Then Chen Xin released the hoe used to fix the car body, started the engine, and went on.


    Because of geological activities, there are abundant geothermal resources underground in this area of Hubei Province. Coupled with abundant water resources, it has created the reputation of hot spring city here.


    In the past, hot springs may only be tourism resources for leisure and vacation. Geothermal development may not have been applied on a large scale due to technical reasons. However, in the present environment, a hot spring can affect the life and death of countless people.


    If we build shelters around hot springs, water, heating, electricity Can be solved with geothermal resources, it can be said that as long as the effective use of geothermal resources, will be able to survive in the present end of the world.


    Thinking of this, Chen Xin can''t help feeling that there is a large circle of hot springs around his city, but there is no hot spring in his city.


    Even the hot spring water in his refuge was produced before because of the earthquake. Even if you want to use geothermal resources, there is not enough geothermal resources to use. You can only use shallow geothermal energy. People have to envy the natural geothermal resources of the surrounding cities.


    However, there are both advantages and disadvantages. Rich geothermal resources also mean that underground magmatic activities are relatively rich. The impact of meteorite impact is likely to intensify geological activities and cause magmatic eruption in weak surface areas.


    For regions rich in geothermal resources, it also means danger.


    Although there are no volcanoes in the boundary area of Hubei Province and Hunan Province, the magma is likely to form new volcanoes due to earthquakes and other reasons. After all, the volcanic belt and seismic belt on the blue star are highly coincident.


    Fortunately, the problem Chen Xin was worried about didn''t happen, and he didn''t see any volcano along the way. Instead, when he arrived at the original hot spring resort, he found a shelter built around the hot spring through the radar on the car and the infrared camera of the UAV.


    "Hot spring shelter? It''s really built around hot springs! " Chen Xin was surprised when he looked at the picture from the UAV on the monitor.


    Although the shelter is built around the hot spring and relies on the original hot spring resort, the surface is still covered with a thick layer of snow, but affected by the relatively high internal temperature, the vent and gate of the shelter have obvious heat sources, which are very obvious under the infrared vision of the UAV.Looking at the refuge in front of him, Chen Xin didn''t rush forward. Although he was curious about the refuge built around the hot spring, he didn''t visit it directly.


    He had just started for a few days, and there were plenty of materials on board, so he didn''t need to replenish them.


    What''s more, even if he needs to replenish materials, Chen Xin still prefers to replenish them after entering the urban area of Chibi, rather than replenishing them in the shelter in front of him.


    Therefore, although he is curious about how to use the geothermal resources in the present refuge, Chen Xin is not the kind of person who will take risks for the sake of his curiosity. After some consideration, he still gives up the idea of contacting with this refuge.


    Along the road to continue to move forward, just in case, Chen Xin released a second reconnaissance drone, so that two drones one after another to monitor their own situation, at the same time, he also turned on the radio next to the console.


    In this car, Chen Xin installed a high-power short wave radio station. Under good conditions, this radio station can transmit signals up to 6000 kilometers away. Last night, when he was idle, he did receive a piece of Russian information.


    Chen Xin didn''t understand Russian very well. He tried to send a reply in English. The other party seemed to be very excited and muttered a lot, but Chen Xin didn''t understand it. The two sides talked with each other for a long time, but they didn''t establish effective communication.


    However, Chen Xin can hear that the other party is very happy to receive the information, and his tone is full of excitement.


    As long as the frequency and conditions are suitable for short wave communication, it is not particularly difficult to talk with people from all over the world.


    For example, in the radio station that Chen Xin turns on now, what comes out is a kind of voice that he can''t understand or even distinguish what language it is.


    Feeling helpless, Chen adjusted the frequency of the radio station, but did not receive any other signals.


    He had to turn off the radio again and drive on.


    It seems that there are many vehicles passing by on the road from this hot spring refuge to Chibi City. It should be left by the communication between this hot spring refuge and Chibi City, which also makes the road smooth and easy to walk.


    Chen Xin is moving along the track, and his speed is also much faster. According to his estimation, he may be able to reach the urban area of Chibi before noon.


    Although the roads are roads, they are actually covered with snow. Even the roadsides are flat, burying all the farmland in Chen Xin''s impression under the snow.


    "I don''t know if these fields can be planted when the snow melts..." Chen Xin had this idea in his mind, but he was soon dumbfounded.


    When the snow melts, there is no shadow. The existence of animals and plants is lost in the soil, and the ecological cycle should be gone. Even if the ashes of the previous global fire can increase the soil fertility as a kind of inorganic fertilizer, when the snow melts, the more than one meter thick snow will turn this place into a muddy swamp.


    Maybe human beings will no longer need to cultivate farmland by then? After all, it''s a long time to wait until the snow melts. During this period of time, human beings are affected by extreme cold and lack of sunlight, and the agricultural production mode should change greatly.


    After all, agricultural cultivation now relies on greenhouses and artificial light sources. Even if the light is restored in the future, the only way to plant land on the surface is to build greenhouses and clear away the snow on the surface. It''s really not easy.


    Coupled with the progress and improvement of human science and technology in a long period of time, maybe at that time, human beings will adopt more efficient planting methods instead of traditional farming.


    Maybe I can develop in this way?


    Chen Xin thinks of the upgraded greenhouse in his home and thinks that the multi-layer and three-dimensional planting system is worth promoting. However, he has no way to copy the system in other places now. Maybe he can study it later.


    He made up his mind that there was no trace of other moving objects behind him, so Chen Xin planned to take back the second reconnaissance drone.


    However, when he was about to do so, the sky suddenly lit up, a bright fireball lit up the dark sky, cut the sky in the rolling smoke, and fell toward the earth.


    Chen Xin looked at the huge fireball in surprise. He was shocked by what he saw. He hadn''t seen what the sky looked like for more than half a year.


    However, as the fireball was getting closer to the ground, he was awakened by the light in front of him. He stepped on the brake in a hurry and let the car stop. At the same time, he quickly put down the hoe under the car to fix the body and prepare for the impact caused by the fireball falling to the ground.

 Chapter 216

    The orange red fire lit up the sky, and the huge fireball crossed the sky like a meteorite and fell down.


    The sky brightened up as if the sun had risen again.


    After half a year, the earth was illuminated again. The vast expanse of ice and snow on the illuminated field reflected the orange red light, as if everything was shrouded in the fire.


    Chen Xin, sitting in the driver''s seat, has smashed the hoes under the car body into the ground, hoping to fix the car body.


    Once such a big fireball falls to the ground, it is bound to cause great impact. Chen Xin can only hope that he will not be blown away.


    However, to Chen Xin''s surprise, the falling speed of the fireball is not fast, or even very slow. Even the UAV that was originally released has returned to the car. This huge fireball has not yet landed, and even seems to be slowing down.


    Chen Xin is very surprised. He stares at the huge fireball seriously and thinks it may not be a meteorite.


    Thinking of this, Chen Xin quickly took out his telescope and looked in the direction of the firelight to see what the fireball was.


    The orange fire light envelops the objects in the fireball, making it difficult for Chen Xin to see what it is. In addition, the magnification of the telescope is not high, so it is difficult for Chen Xin to judge. But from the shape, it does not look like a meteorite.


    "Isn''t it a satellite or something? But why is it slowing down all the time? " In addition to meteorites, the only things that can fall from the sky are spacecraft and so on.


    If it''s a spacecraft, it''s no surprise that it will slow down. Some spacecraft with return program will slow down when they enter the atmosphere to avoid being burned. On the one hand, it is to avoid excessive temperature caused by severe friction between the surface and the air; on the other hand, it is to avoid impact caused by falling too fast.


    And being able to slow down means that this thing should still be working properly.


    Thinking of this, Chen Xin was relieved that he did not need to resist the impact, which made him feel relieved.


    He confirmed that he was not in danger, and the fire light on the surface of the spacecraft in the sky was also weakening, which means that its speed has been gradually decreasing. Chen Xin also looked at it with a telescope with great interest.


    Many people may have seen the rocket launch, but not everyone is lucky to see the picture of such a spacecraft returning from space and landing on the ground.


    It''s just that Chen Xin still thinks it''s a bit strange. Normally, the spacecraft will not land in places like Hunan Province or Hubei Province, because there are too many mountains and there are not enough flat areas, so it''s not suitable for the spacecraft to land.


    Take Yanguo as an example. Normally, the landing area of spacecraft returning from space is usually on the sea or on the desert or Gobi in Mongolia and Xinjiang provinces. The open environment is easy to recycle. Not to mention, it can effectively reduce the damage caused by accidents.


    As for landing in Hunan or Hubei Province, as it is now, it can only be an accident or an emergency.


    Thinking of this, Chen Xin can''t help but worry. After all, this is a spacecraft that is still in operation and can return to the ground by itself, although he doesn''t know why it landed here.


    Maybe you should take a look? Should someone come to recycle such a large spacecraft?


    Chen Xin thought like this. He adjusted the radar on the car and aimed it at the aircraft that had been decelerating gradually and the surface fire had weakened a lot. He wanted to see where it would land.


    However, Chen Xin''s radar performance is not so strong, or the landing spacecraft is not within its scanning range. Chen Xin can only give up the idea of using radar to track the spacecraft, and use telescopes to observe the trajectory of the spacecraft.


    However, when he saw the spacecraft through the telescope again, because the flame on the surface had weakened a lot, Chen Xin could finally see that it was a return capsule.


    Chen Xin is also an astronomy enthusiast, and he is familiar with the spacecraft of Yan state.


    In addition, more than half a year ago, when various countries joined hands to prevent the meteorite from falling, they made lengthy reports on the spacecraft of Yanguo astronauts. At present, the shape of the capsule is impressive for Chen Xin.


    Is this an astronaut returning from space? Chen Xin felt that his brain was not enough. The astronauts came back now and landed here in Hubei Province?


    Chen Xin thought that because of the failure to prevent the meteorite from falling, the astronauts had already died!


    After all, when they first landed on the surface of the meteorite, blasted the meteorite and changed its trajectory, their speed of return was not as fast as that of the meteorite itself. When they arrived at the earth, in fact, the meteorite had collided, causing a global disaster.


    The low earth orbit may be full of meteorite debris, and their spacecraft may be directly hit and damaged by meteorite debris.


    Even if they are lucky enough to escape the impact of meteorite debris, the harsh environment on the surface makes it impossible for them to return. They can only stay in space, or try to break through the atmosphere full of dust and debris, and bet their luck to see if they can successfully land on the ground.It is not particularly strange that they can successfully return to the ground. After all, as long as they are lucky enough, the quality of the spacecraft is excellent enough to guarantee their return.


    As for why they landed in Hubei Province, the earth''s surface is now full of dust and debris. From outer space, the whole surface should be covered with dust. In the absence of sufficient reference targets, it is a miracle that they can still land on the territory of Yanguo.


    The only thing that makes Chen Xin feel strange and incomprehensible is why they returned half a year later.


    How did these astronauts survive for more than half a year? There is no way to carry so much food on the spacecraft. What do they eat and drink?


    However, Chen Xin soon put this problem behind him, because the flame on the surface of the spacecraft had been gradually extinguished, and began to slow down further, and was about to land on the ground.


    Chen Xin saw this, quickly put away the hoe under the body, restart the car, and drove in the direction of the spacecraft landing.


    No matter why the astronauts are returning now or why they are here, now that they are back, Chen Xin feels it is necessary to help them, and he has the ability to help them.


    Driving the car, as fast as possible toward the spacecraft landing direction, Chen Xin constantly looking at the spacecraft in the sky, while also driving the radar power to the maximum, scanning whether there are other people around.


    Chen Xin thinks that it''s hard for anyone to ignore the big news just now. If someone else has discovered the spacecraft and is going this way, the matter will be complicated.


    It''s easy to say if they also want to help, but if someone has a bad idea, it''s not a good thing for these astronauts who have gone through a lot of hardships to return to the ground.


    With this in mind, Chen Xin hesitated for a moment, then took a look at a red switch on the console, which is the switch of the heavy machine gun on the roof. Pressing it down can lift the heavy machine gun on the roof.


    However, Chen Xin did not see anyone else on the radar, so he did not lift the machine gun immediately.


    With Chen Xin approaching, the spacecraft in the sky is about to land on the ground. Three huge parachutes have been opened on its top, and it is further decelerating.


    Chen Xin is chasing the position of the spacecraft. At this time, the vehicle speed is very fast, but it still can''t catch up with the descending speed of the spacecraft. Before Chen Xin reaches the landing position of the spacecraft, it has fallen to the ground.


    Seeing the landing of the spacecraft, Chen Xin can''t help but get nervous. He turns on the radio and tries to call the spacecraft. He hopes that while he can contact the astronauts inside, Chen Xin is also approaching the spacecraft as soon as possible.


    However, no matter how Chen Xin called on the radio, there was no answer or reply from the spacecraft, which made Chen Xin nervous and worried.


    Fortunately, when Chen Xin arrived near the spacecraft in a nervous car, he finally saw that the cabin door of the spacecraft was opened from the inside, and an astronaut in a heavy spacesuit climbed out and fell on the snow.


    Seeing this, Chen Xin quickly stopped the car, put on his protective clothing and got out of the car. He ran a few steps to the side of the astronaut. Chen Xin patted his shoulder and yelled to him, "can you hear me? Are you ok? "


    The astronaut raised his arm, nodded slightly to Chen Xin through the mask, indicating that he could hear him. At the same time, he pointed to the spacecraft beside him, as if to indicate that there was someone in the spacecraft.


    Seeing that the astronauts seemed to be in good condition, Chen Xin put him down and ran towards the spacecraft. Looking inside from the cabin door, he found that there were still two astronauts inside, and they were trying to get out of it.


    One of the astronauts saw Chen Xin appear, his face showed a surprise expression, just ready to take off his helmet, Chen Xin quickly stopped him and said: "don''t take off the helmet, it''s only minus 40 degrees outside! Give me your hand and I''ll pull you out! "


    With the help of Chen Xin, two astronauts finally climbed out of the spacecraft.


    Looking at the three astronauts who collapsed on the ground, Chen Xin was in a bit of a dilemma. He had only one person. He had just pulled two astronauts out of the spacecraft with great efforts. Now it''s not easy to move them to his own car.


    Chen Xin thought about it for a while and said to them, "you wait here. I''ll drive the car."


    After that, he ran back to the car and drove his car over. Then he picked up an astronaut''s arm, lifted him up from the ground and carried him to the car.

 Chapter 217

    "Thank you so much!" In the car, astronauts who have taken off their helmets and heavy spacesuits hold Chen Xin and pour them hot water. They are thanking him.


    "You''re welcome. It''s just a matter of lifting a hand. Someone else will save you." Chen Xin didn''t care too much about the other party''s thanks, but just laughed.


    He was impressed by the three astronauts. When Yanguo sent people to space to change the orbit of the meteorite, he also made lengthy reports on the three astronauts. When Chen Xin watched the live broadcast, he also saw an exclusive interview with them before they set out.


    Looking at the spacesuits they took off and piled on the table, Chen Xinjian seemed to have recovered a lot. Then he asked them, "how do you feel now? I have limited conditions here, and I can''t check for you. If there is anything uncomfortable, please let me know in time. "


    "We''re all OK, except that we''ve been in space for too long and may be a little short of calcium, there''s nothing wrong with everything else." One of the three astronauts answered Chen Xin''s question. Chen Xin remembered that his name should be Zhang Yiguang, but after half a year, Chen Xin could not remember clearly.


    It''s only half a year. What happened at the beginning seems like a long time has passed. Chen Xin thought so in his heart, but said to the three astronauts: "since you have no problem, you should have a good rest in my car first, and then I will pass by the three towns in Hubei Province. I will send you to the official refuge, where you should get help ¡£¡±


    "Thank you very much! But haven''t the state started the haven program? " Next to another astronaut asked, Chen Xin impression he seems to be surnamed Zhao, but the name has been completely forgotten.


    Facing the problem of the astronaut surnamed Zhao, Chen Xin nodded with certainty: "the shelter plan started very early. When you went to heaven to save the world, most people had already evacuated to the shelter ahead of time. The disaster caused by the meteorite impact did not cause large-scale casualties. At least most people in my City survived."


    "That''s great!" There is a trace of happiness and guilt on the faces of the astronauts.


    Chen Xin looked at them and didn''t know what to say.


    He can understand the guilt of these astronauts. After all, in their view, it was their mission failure that caused the meteorite to hit the blue star. If their original mission could succeed, the blue star would not have such a disaster.


    Chen Xin also watched the live broadcast at that time. He clearly remembers how these astronauts risked their lives to install thrusters on the meteorite. Their actions can be said to have done their best.


    No one has the right, no one has the right to reprimand them, let them to be responsible for the disaster of blue star.


    Slightly shook his head, Chen Xingang is going to say something to comfort them, but the radar in the cab suddenly issued an alarm.


    The three astronauts, still immersed in their emotions, suddenly became nervous and looked up at Chen Xin. They didn''t know what had happened.


    "It''s the radar. I''ll see what''s going on." With that, Chen Xin ran to the cab.


    Sitting in the driver''s seat, Chen Xin manually launched the UAV while looking at the radar display screen. On the display screen, four bright spots appeared in the radar scanning range one after another, and were approaching the location of Chen Xin and the return capsule.


    "What happened? Is there anything we can do for you? " Three astronauts also came to the cab, seems to want to help.


    "There are other people coming. They should have seen you fall from the sky. That''s why they came here." Chen Xin explained to the three people that he was operating the UAV to fly in the direction of four bright spots at the same time, and the infrared camera of the UAV also sent the pictures back to the screen of the console in real time.


    The three astronauts are high-quality talents with professional training. Naturally, they can''t understand the pictures taken by the radar screen and infrared camera. Naturally, they can see that the four bright spots on the radar screen are four cars.


    Looking at the pictures taken by the UAV, Chen Xin frowned, turned to the three astronauts and said, "they should have come for you and the re-entry module, but I''m not sure if they are kind-hearted. After all, no one knows what will happen in this environment, so you''d better stay in my car and go to Sanzhen with me."


    For the immediate situation, the three astronauts quickly made a judgment.


    Although they have just returned to the ground, they also speculated about what the current situation is before they decided to return. Although the exchange with Chen Xin was very short, they can also speculate what the current situation is in Yanguo from the implementation of the refuge plan.


    Chen Xin was able to rescue them at the first time, which made the three astronauts have a preliminary trust in Chen Xin, and Chen Xin''s car also gave them a great sense of security. In this case, they are willing to trust Chen Xin''s judgment.


    As for the four approaching vehicles, the three astronauts are on guard. This is not before the disaster. No one can guarantee that the four vehicles are here to help, or that they are only here to help.It''s necessary to be on guard.


    However, as the captain of three astronauts, Zhang Chengguang, who was recorded as Zhang Yiguang by Chen Xin, still said to Chen Xin after whispering with his two companions, "can you contact them, please?"


    "Touch it? I don''t recommend you to do this. If they have any ideas, I''ll be alone, you''ll be three, and they don''t have any weapons. Once they see what they want, things will become very troublesome. " Chen Xin frowned and didn''t quite agree with Zhang Chengguang.


    Although the four cars for the heavy machine gun he installed on the roof of the car are just a few things that can be exploded by firing, Chen Xin still doesn''t want to casually expose this kind of big killer without revealing his weapons.


    "You can''t take the re-entry capsule with you, can you? If these people can help to transport the re-entry module, we still hope to recover it. There are some very important data on it. If we can, we can''t give up the re-entry module. " The last astronaut who didn''t say much began to explain.


    Hearing this, Chen Xin didn''t like it, but after thinking about it for a while, he asked, "should there be a data memory? Can you take that off? These people may not be good people. I''m not sure what they will do. "


    "This..." Chen Xin''s words made both astronauts look at Zhang Chengguang.


    "If I have tools, I can take them down, but it will take a little time." Zhang Chengguang nodded, indicating that he could dismantle the data memory.


    In Zhang Chengguang''s view, if the people on the four vehicles are malicious people, as Chen Xin said, then it is the best choice not to contact them rashly. However, they can not give up the re-entry module, so it is the best choice to take the data brought back from them.


    Hearing what Zhang Chengguang said, Chen Xin took him to the life cabin without saying a word, found out the toolbox on the car, handed it to him, and asked him, "it''s cold outside. Do you need help?"


    "It''s very small in the re-entry capsule. I''m more agile by myself, but I need a little time to buy me ten minutes." Zhang Chengguang is ready to get off with his toolbox, but Chen Xin throws his protective suit to him.


    Facing Zhang Chengguang''s eyes, Chen Xin said: "put on, it''s only minus 40 degrees outside, you can''t carry it for ten minutes."


    With that, he went back to the cab, looked at the bright spots on the radar, and yelled to Zhang Chengguang, "they are still eight kilometers away from us. If you hurry up, we can leave before they come."


    Zhang Chengguang answered, put on Chen Xin''s protective clothing, got out of the car with the toolbox, and ran towards the return capsule.


    Chen Xin can naturally see the situation outside the car from the inside. While watching Zhang Chengguang''s action with the other two astronauts, he glances at the machine gun control switch on the console, but suppresses his impulse to use the machine gun.


    "Can you bring the drone closer?" The astronaut surnamed Zhao approaches Chen Xin and looks at the image captured by the infrared camera of the UAV on his console. He feels a little fuzzy, so he asks Chen Xin.


    Chen Xin nodded, stretched out his hand and scratched on the touch screen of the console. The camera soon drew closer.


    Under the infrared camera, all the situations on the four vehicles were photographed, so that Chen Xin and two astronauts could see clearly the situation on the vehicles.


    , this is just four ordinary civilian cars, each car has three to four people, but the most important thing is that they all have sticks, shovel and other weapons, including three of the three people in a car with a flash of gun.


    "These people don''t look like they''re coming from the right place!" The two astronauts were surprised to see this.


    They didn''t expect that things were really like what Chen Xin said. The people on the four cars that came here all looked ill intentioned.


    Looking at the four cars approaching, Chen Xin picked up the walkie talkie hanging on the console, cut to the horn outside the car and said, "all the people in the four cars are armed, and some of them are armed. It''s fast. You don''t have much time. They are only seven kilometers away from us."


    Zhang Chengguang, who is dismantling the data memory in the outside re-entry cabin, hears Chen Xin''s voice. First, he pauses. After hearing what Chen Xin says clearly, his speed of dismantling is obviously accelerated. He takes out a box from under the seat of the re-entry cabin. After opening it, he takes out a self-defense pistol and a signal gun from the inside and puts them aside for a rainy day .

 Chapter 218

    Although Zhang Chengguang just came down from space, his hands and feet are in a state of powerlessness, and even his own walking belongs to gritting his teeth and insisting on it, he still dismantled the data memory in the re-entry capsule as soon as possible.


    In Zhang Chengguang''s opinion, the data storage is more important than himself and even the other two astronauts. That is all the observation data of the blue star from the space station Tiangong in the past half a year.


    After the initial mission failed, they were unable to return to the blue star, so they took control of the spacecraft and went to the Tiangong space station, which used to be the operation support base.


    Tiangong space station has a large amount of fuel and supplies for this mission. Although most of the fuel has been supplied to the three spacecraft flying to the meteorite in the previous mission, the supplies are still very sufficient.


    After they arrived at the Tiangong space station, they tried to use the communication equipment on the Tiangong space station to get in touch with the blue star. Indeed, they once got in touch with the command center to observe the meteorological and other data of the blue star according to the requirements of the command center, so as to provide data support for scientists to analyze the impact caused by the meteorite impact.


    But with the fall of the meteorite, the dust completely covered the entire blue star, and their communication was seriously disturbed, so they could hardly get any more contact with the ground.


    In the next few months, although they had been trying to resume communication with the ground, they had little effect. They could only receive a little bit of ground signal sporadically, but most of them were disorderly civilian radio signals.


    As for the communication with the command center, it has been unable to recover.


    In a few months, they gradually exhausted the supplies in the Tiangong space station, but in desperation, they decided to risk using the return capsule to return to Bluestar.


    It''s almost a gamble, because they only have one return capsule. Once they start to return, there is no chance to fail again.


    And landing failure, for them, is just a dead word.


    The three astronauts didn''t care about their own life and death. They were ready to sacrifice for their country long before they set out to carry out the mission.


    However, they have to find a way to hand over a large amount of valuable data collected from the Tiangong space station to the state in any case, which is far more important to them than the lives of the three of them.


    That''s why they took the risk of landing in the densely populated area along the Yangtze River, rather than in the sparsely populated northern desert.


    On the one hand, this is to facilitate rescue after landing. On the other hand, they are considering that in case of landing failure, their wreckage will fall in this area. As long as someone can find the re-entry module, the data memory in the re-entry module will also be found.


    In this way, even if they are sacrificed, these precious data can still be returned to the surface of the blue star and sent to scientists.


    However, they seemed to be lucky. When they landed, although the shell of the re-entry module had been hit by all kinds of debris and dust, so that the shell of the re-entry module had been smashed out of shape, but it was not damaged, and they were still sent back to the surface of the blue star very smoothly.


    However, the situation on the ground is worse than they expected. If Chen Xin didn''t happen to save them, the three astronauts with soft hands and feet would not be able to find refuge in the cold weather of tens of degrees below zero.


    After all, even if they are strictly trained astronauts who have stayed in the space gravity free environment for more than half a year and suddenly return to the earth''s surface, it is impossible for them to make a long journey in their space suits of more than 20 kg.


    Not to mention that they have to face the ill intentioned survivors in the wind, snow and darkness, and hand over the data storage they bring back to the country.


    Fortunately, they are really lucky to meet Chen Xin, who has the ability to help them, but also has no bad ideas for them.


    Zhang Chengguang quickly disassembled the data memory. Although cheap disassembly was considered in the original design, in order to protect the data memory itself, it was fixed very firmly, and more than one had to be disassembled.


    Zhang Chengguang''s hands don''t work hard. He does everything easily in a gravity free environment. After half a year, his body has been used to the gravity free environment. When he suddenly returns to the gravity environment, he can''t help feeling that everything is hard to do.


    But now is not the time to worry about this. He has to remove several data memories as soon as possible.


    Zhang Chengguang''s action is not slow. He said it took ten minutes, but it only took more than five minutes. Only the last two data memories needed to be disassembled were left. At his speed, he could do it all in three minutes.


    Only at this time, Zhang Chengguang''s ears also heard the sound of the car engine, the four cars have approached.


    This made Zhang Chengguang anxious, but he didn''t panic. He pulled the pistol on the side directly, and then continued to tear down the data memory against the clock.


    Chen Xin and the other two astronauts on the car were also worried. They saw the four cars in sight earlier than Zhang Chengguang.These cars didn''t hide their intention at all. The light of the headlights penetrated through the night and came directly. There was no arrogant cover up at all.


    Chen Xin gritted his teeth. These four cars are no threat to him. His car has armor protection, even the windows are bulletproof, and there is a heavy machine gun on the roof. It can be said that Chen Xin is willing to solve these guys every minute.


    However, the existence of the three astronauts makes him worry about exposing his heavy machine gun. If it''s just pistols and other weapons, Chen Xin believes that the three astronauts won''t go deep into anything, but the meaning of heavy machine gun is quite different. Even in this era of doomsday chaos, it''s not something ordinary people can load into their cars.


    However, if things come to a time of last resort, Chen Xin will not hesitate for such a small matter. Four ill intentioned cars and three astronauts will not let him catch up with him for the sake of confidentiality.


    "I''ll go down and help Lao Zhang!" An astronaut stood up and wanted to get off, but Chen Xin stopped him.


    "It''s more than 40 degrees below zero outside. You''re looking for death if you go out like this!" Chen Xin''s tone is not polite, and another astronaut also cooperate to pull the astronauts who want to get off.


    It''s more than 40 degrees below zero, which is extremely cold that the human body can''t bear. Without enough protection, it only takes more than ten minutes to freeze a person, and it can directly freeze to death in half an hour.


    That''s why Chen Xin gave his protective suit to Zhang Chengguang to stop the astronauts from getting off the train.


    As for the spacesuit that astronauts used to wear, although it has very good protective performance and the total weight is less than 20 jin, it takes more than ten minutes to put it on, so it''s too late.


    In this case, Chen Xin thought about it for a moment and then started his car. He put the car body between the direction of the four cars and the return cabin to form a protection for Zhang Chengguang.


    However, Chen Xin didn''t stop the engine. He just stopped the car. At the same time, he picked up the phone hanging on the console and handed it to the astronaut. He said to him, "you can shout to the outside. You can say something to scare those people first."


    The astronaut immediately understood Chen Xin''s meaning, and quickly, as he said, took the phone and yelled out. Chen Xin was also very impolite and turned on the loudspeaker outside the car to the maximum volume.


    "Stop the traffic ahead now! Stop the vehicles ahead immediately! This is Yanguo space agency. It''s on a secret mission! No one is allowed near! Please stop at once! Otherwise, we will take military measures to drive away! " Although Chen Xin and two astronauts were on board, the astronaut seriously pulled out the flag of the space agency.


    For ordinary people, the space agency and secret missions are enough names to scare them from some ideas they shouldn''t have. Even in today''s Doomsday, Yanguo''s national institutions still have full deterrent power.


    Sure enough, under the bombardment of the loudspeakers, the four cars that had rushed towards Chen Xin''s location all stepped on the brakes, braked on the snow and stopped several hundred meters away from Chen Xin''s car.


    Clearly, deterrence is working.


    The four cars parked in the distance seem to be hesitating. If the other side rushes over regardless, Chen Xin can only turn over the heavy machine gun on the roof and blow them up one by one.


    And now they stop, not only to save themselves, but also to keep Chen Xin from exposing the heavy machine gun.


    However, no one knows how long this deterrent will last. Maybe these people will take risks in the next moment, or maybe the name of Yanguo space agency can scare them away. But for Chen Xin and the three astronauts, all they need is a few minutes'' delay.


    Seeing that the four cars just stopped and did not withdraw, Chen Xin signaled the astronauts beside him to continue to shout. At the same time, he launched a second UAV and approached the four cars with two UAVs, posing a threatening posture.


    Chen Xin doesn''t know who these people are, but no doubt his operation has calmed them down and made them dare not act rashly.


    Zhang Chengguang, on the other side, naturally heard the sound. He quickly removed the last data memory, packed up his tools, held six data memories in his arms and was ready to take them away, but the heavy weight was not easy to take.


    This makes Zhang Chengguang suddenly anxious, he almost did not hesitate to take off his protective clothing, put six memories in the protective clothing, and he climbed out of the re-entry capsule with the protective clothing.


    The air-conditioning immediately eroded his whole body. Zhang Chengguang felt a piercing cold, but it didn''t affect his movement. He rushed to Chen Xin''s car quickly, and Chen Xin, who had been staring at this side, opened the door when he rushed.


    Standing at the door of the car, two astronauts saw Zhang Chengguang rushing over and quickly reached out to pull him into the car.


    Seeing Zhang Chengguang getting on the bus, Chen Xin quickly closed the door, and no matter what the reaction of the four cars was, he drove away from here with a bang of the accelerator.

 Chapter 219

    The people on the four cars were obviously not willing to be fooled, and immediately caught up with them.


    However, they did not catch up with all four vehicles, and one remained in place, presumably trying to get the re-entry capsule away.


    Chen Xin saw the pursuers behind him through the pictures taken by the UAV, but he didn''t care too much. If it''s just this kind of pursuit, his car won''t be afraid of anyone.


    "Ask if we''ve got everything. If there''s nothing missing, we''ll leave." Chen Xin looks at the astronaut on one side and signals him to ask Zhang Chengguang if there is anything missing, but the main thing is to see Zhang Chengguang''s state. Just now Chen Xin saw him take off his protective clothing.


    The astronaut nodded and left, while Chen Xin controlled the car to move forward. Although the three cars behind were very tight, they still couldn''t catch up with Chen Xin.


    The reason why he didn''t leave at high speed was that he was worried that Zhang Chengguang still had something missing.


    If there is anything that needs to be taken back, Chen Xin will impolitely bump all the three cars out here, then drive back to solve the problem of the last car, and then take the things.


    The reason why he didn''t do this just now is that Zhang Chengguang was not in the car. In case Chen Xin went to bump into someone, he would be in great danger.


    "Lao Zhang said that the data memory has been brought up. Although the things in the cabin are valuable, they are useless to ordinary people." The astronaut looked at the data memory Zhang Chengguang brought back, and then came back to explain the situation to Chen Xin: "in addition, Lao Zhang brought up the self-defense pistol prepared for us in the return capsule. He said that when you send us to the place, the pistol can be left to you."


    For astronauts, a pistol is nothing, as a reward to Chen Xin is no big deal.


    Of course, they would not have done this before the disaster, but after what happened just now, Zhang Chengguang clearly has a clear understanding of the current situation and environment. In his opinion, it is a good deal to exchange a pistol for Chen Xin''s help.


    Chen Xin didn''t care about this. He just nodded, sped up the speed, threw away the three cars behind him, and then readjusted the direction on the map, heading for Chibi City according to the original plan.


    After experiencing such a crisis, Chen Xin and three astronauts became familiar with each other and learned the names of Zhao Wu and Zhang Yao besides Zhang Chengguang.


    When the car stops at the side of the road, Chen Xin returns to the life cabin, and the six data memories that Zhang Chengguang removed from the cabin are placed on the table in front of him.


    Looking at the six black brick memories, Chen Xin didn''t show much curiosity. He just said hello to Zhang Chengguang and the other two astronauts and asked, "it''s almost lunch time. What would you like to eat?"


    Hearing Chen Xin say eat, the expressions on the faces of the three astronauts are vivid.


    For more than half a year, what they eat in the sky is space food. Although the treatment of astronauts is very good, what they eat is nutritious and delicious, and there are even a variety of dishes to choose from, they still miss the food on the ground more.


    Chen Xin just looked at their vivid expression, but threw a basin of cold water on them: "I brought a lot of food, including canned food and shelter food, and some energy bars. I''m still full and full."


    "Can, energy bar?" The three astronauts looked at each other, and finally Zhang Chengguang asked: "is the shortage of materials to this extent? Don''t the state have emergency reserves, meat and vegetables? How come there''s only cans and bars? "


    "National emergency reserve? I don''t know about that. Maybe my city didn''t use it. " Chen Xin shrugged his shoulders. In the puzzled eyes of the three astronauts, he took out a shelter food from the cupboard and put it on the table: "this is a standard shelter food. It contains rice from the reserve before the disaster, rat meat and Tenebrio molitor raised after the disaster, mushrooms from the underground greenhouse, and a small number of fresh vegetables.


    Such a standard shelter food is all the food that the survivors in the shelter can get in a day. The two energy bars in it can only be received by people who go out to work, and the ordinary people have only one. "


    Chen Xin''s introduction obviously shocked the three astronauts who had just landed, but it''s no wonder that when they went to heaven, the disaster had not really come, and the material supply was normal.


    When they were in the sky, they also ate standard astronaut supplies. Although they estimated the situation on the surface, they did not expect that the conditions would really become so difficult.


    "We eat this. This should be enough for the three of us." Zhang Chengguang picked up the shelter food on the table and decided that the three of them would eat the shelter food, which could be regarded as adapting to the current material shortage in advance.


    Chen Xin smiles, waves his hand, and takes out dehydrated vegetables and rice, as well as a canned luncheon meat from the cupboard: "although the official shelter does eat the one you have, I still have something else. Fruits are really not available, but dehydrated vegetables and rice are still available. Canned luncheon meat is available. I hope you don''t dislike it."With that, Chen Xin put a pot on the electromagnetic cooker of Liuli platform, ready to make lunch.


    "This It''s really expensive for you Zhang Chengguang looked at the food Chen Xin brought out, and could only be so polite.


    After all, if what Chen Xin said is true, the food he brings out now can be regarded as a very rich treat in the current world.


    But it also made the three astronauts deeply worried about the current situation of Yanguo.


    after lunch, Chen Xin still drove through Chibi City according to the original plan. There was no accident that he found the refuge in Chibi City. However, neither Chen Xin nor the three astronauts on board wanted to stop and communicate with the official refuge in Chibi City.


    Chen Xin did not need to stop to replenish because he had sufficient supplies, while the three astronauts felt that the data they carried was too important. It was better to do more than less. It was much better to go directly to three towns than to waste time in such a county-level city.


    After all, Chibi City is only a county-level city. Even if they contact the local government and the official shelters, they can get very limited help. The most they can get is to add some supplies or send a few policemen or armed police to protect them.


    But for Chen Xin and the three astronauts, it is not necessary or meaningful.


    It''s safer to go directly to the three towns than to attract unnecessary attention just to help a few people.


    So they quickly passed through the urban area of Chibi and drove along the road where there was no trace of the road at all.


    Zhang Chengguang, the co driver, looked at the darkness outside the window and asked Chen Xin, "do you live in such an environment for more than half a year?"


    "It''s not all. It was good at the beginning. In the first month, because the meteorite had just hit, there were fires everywhere, and they couldn''t get out of the house, so they stayed in the shelter to hold on. Except for a little bit of hardship, it was also good." While driving, Chen Xin chatted with Zhang Chengguang. He found that Zhang Chengguang was actually a very talkative person: "after the first month, the temperature was not very low. At that time, the environment was not as bad as it is now, so most people came out to collect materials for exchange.


    However, the network has been cut off, and the mobile phone can''t get through. Only some official wired phones can make calls. It''s hard to get the situation in other places, and I don''t know the situation in other places. However, the municipal government in my city can still guarantee the supply of materials. Although life is a little hard, it can still live without lack of food and clothing. "


    "Sounds like it''s good?" Zhang Chengguang couldn''t help showing a little surprised expression. According to Chen Xin, the situation is really good.


    Chen Xin also nodded his head and affirmed his words: "the last few months were really passable, basically the same as those in the 1970s and 1980s or earlier, and the food was guaranteed. Generally speaking, it was really good.


    However, when the temperature came down, it was more difficult. The low temperature of tens of degrees below zero, unless there were enough cold clothing or protective equipment, people would freeze in less than half an hour when they went outside.


    Although the underground shelter can withstand part of the cold, it can still kill people without heating. Moreover, under the low temperature environment, both crop growth and animal breeding have been greatly affected. A friend''s greenhouse was almost destroyed. "


    "Cold, dark..." Zhang Chengguang''s mood has become a bit complicated and uncomfortable, and his self reproach surges up again. If their task had not failed at the beginning, maybe they would not have suffered all this.


    Chen Xin seemed to see his idea and said to him, "don''t take the responsibility too much. You''ve done your duty and done what you can do. As for the situation, no one wants to, but now that it''s done, let''s look ahead! The most important thing is to strive to live and live in the present


    "Thank you Comforted by Chen Xin, Zhang Chengguang smiles at him, but he still can''t get over the hurdle.


    How can this kind of thing be passed with a few words of comfort? Maybe we have to wait for Zhang Chengguang to figure it out.


    Chen Xin did not continue to tangle, continue to drive, along the dark direction of the "road" forward.

 Chapter 220

    With three more people on board, Chen Xin is still an astronaut, a super elite who has been trained systematically and professionally. Naturally, he saves a lot of effort.


    Besides, three astronauts can rotate with him in the matter of driving, even though he can make the operating system drive automatically by himself before.


    Moreover, the three astronauts are experts in all kinds of professional knowledge. The planting box Chen Xin placed in the life cabin was manipulated by Zhang Yao and planted vegetables.


    "I didn''t expect that astronauts could grow vegetables? You don''t just know how to fly a spaceship. " Chen Xin looked at Zhang Yao watering the planting box and adjusting the temperature, and couldn''t help laughing at him.


    "Ha, astronauts need to know everything. They can only fly a spaceship, but they can''t go to heaven." Zhang Yao also laughed at Chen Xin, but explained to him: "before this disaster, the space agency had been preparing for a manned lunar landing, and we had been preparing for it.


    According to the plan, a large number of scientific experiments will be carried out in the process of going to the moon, including experiments on crop cultivation. I am the person in charge of the experiments, so I have received a lot of training in this field.


    I didn''t expect to go to the moon. Instead, I went to a meteorite. It''s a mistake. I just don''t know if I''ll have a chance to go to the moon in my life. I''ve been preparing for it for ten years! "


    Zhang Yao said with emotion on his face.


    Chen Xin can understand this feeling. The astronauts are all selected from the pilots. The pilots themselves are the elites of one in a million, and the astronauts can be described as the rarity of one in a million. There are more than a dozen astronauts selected by more than one billion people in the country, and one in a million is considered to be affluent.


    And these astronauts are selected and have to go through a lot of training, but they may not be able to really go into space.


    Since the beginning of the manned space program, Yanguo has selected more than a dozen astronauts, but only a few of them have ever been in space. Among the remaining astronauts, there are those who have never been in space in their lifetime.


    As Zhang Yao said, he has been preparing for the moon landing for ten years, but how many years can a person waste?


    And he was lucky, at least to be able to go into space.


    "If you think so, you''ve been in space! And it may be that for a long time in the future, human beings will finally be able to land in space. Now that the dust in the sky does not disperse, there is no way to continue to engage in space Chen Xin patted Zhang Yao on the shoulder and joked at him.


    Chen Xin and Zhang Yao may be close in age.


    "You''re right. At least I''ve been in space and lived there for half a year!" Zhang Yao also laughed, and soon adjusted his mood: "these seeds are growing well. As long as you take care of them carefully, you can harvest them soon. Moreover, your planting box is very good, and its functions are very comprehensive. Where did you buy it?"


    "I made it myself. In the end, I can''t survive alone without understanding these things. In this environment, even if I want to buy it, there''s no shop open! It''s not like you used to be able to shop online. " Chen Xin smiles and explains why he has to do it himself.


    Zhang Yao couldn''t help patting his forehead, knowing that he was thinking badly.


    He went to space before the disaster. He had been in space for more than half a year before, but now he has not changed his mind. He still stays in the mode before the disaster.


    So it''s no surprise that Chen Xin bought his planting box.


    However, Zhang Yao also knows that now is not the past, so he is trying to adjust his mind as much as possible, trying to adapt to the present doomsday.


    "Comrade Chen, can you tell me more about the present situation? We spent more than half a year in the sky before, but we still don''t understand the situation on the ground. Can you tell me more about it? I also know a little bit more about it and try to adapt to the present life as soon as possible. " Zhang Yao asked Chen Xin to tell him more about how people lived after the end of the world.


    "Not bad, but not good." Chen Xin nodded slightly, then shook his head and explained: "the official shelters have attracted a lot of survivors, so the living conditions are certainly not as good as those of private shelters like me, but it can''t be said that it''s very bad. At least we can have three meals, food and clothing, a place to live, medical and health care and so on. Although the days are hard, we can still live. ¡±


    "if I hear you say that, I have a bottom in my heart. If we can live well, then everything will be better." Zhang Yao is very optimistic. After listening to Chen Xin''s words, he feels that things are not as bad as he thought.


    For Yanguo people, as long as they can survive, there will be no problem. They can always rebuild their homes and make life better and better.


    Although he had been in the sky for more than half a year, he did not know how the country on the ground was arranged, but both Zhang Yao and Chen Xin believed that Yan state must have a set of plans to rebuild the country.


    It''s not that when a disaster comes, you can only ask God''s blessing, place your hope on the illusory gods, or think that this is what punishment you can only endure, rather than trying to save yourself.When the sky is broken, you can mend it by refining stones; when the flood comes, you can dredge the river without asking the prophet; when the disease is prevalent, you can try medicine and cure it by yourself without seeking miracles; when you drown in the East China Sea, you can fill up the East China sea, and if you are exposed to the sun, you can shoot down the sun


    For the people of Yanguo, we will never be lambs on our knees, nor will we yearn for the illusory grace of God. We will only wipe our blood and tears, lick our wounds, and then stand up to rebuild our home.


    Therefore, for every Yan people, they have never doubted that they can rebuild their homes. They just have doubts about when and how to rebuild their homes.


    In fact, judging from the current situation, after the first wave of disasters, all parts of the country have begun to gradually resume production and rebuild their homes.


    Just as Chen Xin and Zhang Yao were discussing these matters, Zhao Wu came over from the cab and said to them, "it''s going to Xianning City ahead. Lao Zhang asked me if I want to go to the city to supply."


    "Are you in Xianning?" Chen Xin was surprised. Xianning is also one of the important cities in Hubei Province. After that, further north is the three towns.


    "It''s almost here. Because I''m in a hurry, Lao Zhang drives faster." Zhao Wu nodded.


    Because the three astronauts were in a hurry to send the data storage to the state as soon as possible, so when the three astronauts drove, their speed was obviously faster than Chen Xin''s.


    Chen Xin has no doubt about this, but he still went to the cab, opened the map on the console, carefully checked it, then nodded and said: "the materials on the car are still sufficient, there is nothing to add. As for fresh water, there is still half water in the water tank, which is enough to drive to three towns."


    "So we don''t go into the city to supply?" Zhang Chengguang asks Chen Xin for his opinions. Although there are three of them, Chen Xin owns the car, so we should listen to his opinions.


    Chen Xin nodded and said, "just go through the city as before."


    Chen Xin''s decision can be said to be in Zhang Chengguang''s favor. Now he is eager to drive all the way to Sanzhen directly. So since Chen Xin says he doesn''t need supplies, he doesn''t drive to Xianning City. Instead, he drives along the road outside the city and intends to pass directly.


    However, Zhao Wu was still worried. He asked Chen Xin curiously, "doesn''t this car need gas? We''ve passed two cities. Chen Xin, you don''t go to refuel. Is the oil in the tank enough to support three towns? "


    When it comes to this problem, even Zhang Chengguang is very curious. He chimed in and said, "yes, Chen Xin, your car is a bit strange. There is no fuel gauge on the dashboard. Is your car a rechargeable car?"


    Zhang Chengguang''s last remark is obviously a joke. Electric cars are very common, but electric trucks are still rare. He just said it casually, but he didn''t expect to make a guess.


    "The car does use batteries, so don''t worry about refueling." Chen Xin didn''t say much. He just pointed it on the console and called out the power display: "the three batteries on the car are basically full. Even if I drive to the imperial capital, I won''t be out of power."


    "What battery is so powerful? Has our country made a breakthrough in electric energy storage in the past six months? " Zhao Wu''s first reaction to Chen Xin''s words is that he doesn''t believe it, because no electric car dares to say that he can run from the Yangtze River to the imperial capital and then come back without charging.


    Even if it''s an oil burning car, it''s not enough unless it''s equipped with an oil tank.


    However, Chen Xin did not answer this question. Although isotope thermoelectric battery is not a great technology, it is not a technology that should be used in civil vehicles. Moreover, the isotope thermoelectric battery Chen Xin used is obviously different from the "ordinary" isotope thermoelectric battery.


    Seeing Chen Xin''s evasion, neither Zhang Chengguang nor Zhao Wu pursued it. This is obviously Chen Xin''s secret, and they are not the kind of people who want to get to the bottom of the matter.


    The three people in the cab were all silent. Zhang Chengguang was driving along the road. However, just after the car had passed the downtown area of Xianning and was about to cross a road, they were stopped.


    Looking at the roadblocks at the intersection and the checkpoints nearby, Zhang Chengguang and Zhao Wu look at Chen Xin. They don''t know what''s going on now. They can only hope that Chen Xin can know what''s going on.


    However, Chen Xin is also puzzled about this, but he still motioned Zhang Chengguang to stop the car, and then got up from the driver''s seat. Instead, he sat in the driver''s seat, intending to see what happened first.

 Chapter 221

    Chen Xin slowly stopped his car in front of the roadblock and watched a few bloated people come out of the roadside inspection station. One of them went to the window and lowered the window. He asked: "master, what''s the matter?"


    "Routine check, where are you from? This car is good enough! " The man who went to Chen Xin''s window looked at Chen Xin''s car, but he didn''t show any seriousness. He just explained to him, "now all the cars from Xianning to the three towns must be inspected. The three towns are more strict. If you go to the three towns, there are still several inspections ahead."


    Hearing this, Chen Xin didn''t say anything. Instead, Zhang Chengguang asked: "master, what''s the matter with such strict investigation in three towns? Is something wrong? "


    "Are you from out of town? It''s not that there''s something wrong with the three towns, it''s just that they are more strict. After all, the distribution of materials in the central part of the country depends on the dispatching and regulation of the three towns, and the management of personnel and vehicles in and out of the country is more strict. " When the inspectors heard Zhang Chengguang''s question, they didn''t find it strange.


    Although the transportation between different places basically depends on the railway, and the highway transportation is almost cut off, it does not mean that there is no car to run.


    At least since the establishment of this checkpoint, basically every two or three days a car can be seen. Although most of the cars come from the three towns, it is not that there are no cars going from here to the three towns. Therefore, this checkpoint is not a complete decoration.


    "What''s in your car? We need to get on the bus and check it. In addition, you can take out your pass. I''ll have a look. You need a pass to get in and out of the three towns. " The inspectors didn''t have bad behavior or bad looks, or took the opportunity to ask Chen Xin what he was doing, but they just carried out the inspection procedure normally.


    Chen Xin didn''t resist the inspection. He just said "just a moment", then he closed the window and planned to open the door.


    Before opening the door, he gave Zhang Chengguang and the other two astronauts a wink, let Zhang Chengguang receive the pistol, and let the other two astronauts raise their vigilance.


    Chen Xin opened the car door. Although there were several inspectors outside the door, only two of them came up. Moreover, there was no detailed search after they came up. They just completed the inspection after a simple turn.


    Only when they saw the green vegetables that had just sprouted in Chen Xin''s planting box, their faces showed an expression of desire.


    Chen Xin can see that they should have not eaten fresh vegetables for a long time.


    However, the inspector just swallowed his saliva and ignored Chen Xin''s planting box. He did not put forward any requirements. This surprised Chen Xin a little. He thought these inspectors would make some gray income.


    "Why do you three look a little familiar? This dress is printed with" Yanguo aerospace " The inspectors turned their attention to the three astronauts.


    Because they are still wearing the usual clothes of astronauts and have not changed their clothes, they still look conspicuous.


    As for the spacesuits they took off, Chen Xin had already received them in the cabinet and did not put them outside. The inspector did not immediately think that they were astronauts.


    "They''re from the space agency. Doesn''t that matter?" Chen Xin stood in front of the inspector and asked him, blocking his sight by the way.


    For the three astronauts, this is not the time to reveal their identities.


    "Oh, nothing. No wonder you''re going to three towns. Is it the space agency''s business?" The inspectors didn''t ask in detail. After a simple sentence, they said to Chen Xin, "do you have a pass? Now you need a pass to go to three towns. "


    "Pass?" Of course, Chen Xin didn''t. He looked at the three astronauts, and they obviously couldn''t know about it. So Chen Xin said frankly, "we are from Hunan Province. We don''t know what kind of pass is required by the regulations of Hubei Province? If not, where should I go? "


    When Chen Xin said that there was no pass, the inspectors didn''t take it seriously. Although they couldn''t pass without a pass, Chen Xin didn''t pay special attention to it since they didn''t break through. He just explained: "the pass is issued by the provincial government of Hubei Province. You need a pass to enter the three towns or travel in Hubei Province. If you come from Hunan Province, do you go to Chibi? Is there no one over there to stop you? "


    Chen Xin was a little surprised. The management of Hubei Province was different, but he explained: "I came from Chibi, but I didn''t meet the checkpoint. Where should I apply for the pass? Can I get a car from other provinces? "


    "Oh, it''s simple. Just go to the municipal government to handle it. There''s a special department to handle it. It''s also OK to register cars from other provinces." The inspectors explained to Chen Xin the process of handling the pass, and then said to Chen Xin, "if you want to go to the three towns, you must go to the municipal government to handle the pass, otherwise you can go here, and the three towns also need to check. There are several inspection stations along the way."


    "I see. Thank you very much." Chen Xin said thanks to the inspectors, and by the way, he took out two energy bars and handed them to him: "you work hard."For the energy bar Chen Xin handed over, the inspectors still want to refuse, but Chen Xin has been forced to put it in his hand.


    With Chen Xinsai''s energy wand, the inspector hesitated for a moment. He gave it to another inspector who was also on the bus, and then received the remaining one in his pocket.


    The two inspectors tacitly said that they didn''t say anything after they received the things in their pockets. However, they didn''t dare to let Chen Xin''s car go. They still said that he would go to apply for the pass, but the two inspectors also told him who could handle it faster.


    After thanking the two inspectors and getting them out of the car, Chen Xin turned around and drove the car away from the checkpoint, but instead of going far, he stopped at the side of the road.


    "So we''re talking about getting a pass or not?" Zhao Wu saw that Chen Xin called the three astronauts together and took the lead in asking questions.


    However, Zhang Chengguang shook his head, took a look at Chen Xincai and said, "the pass must be handled. Chen Xin, what you are worried about is whether we should disclose our identity?"


    Chen Xin nodded, which was exactly what he was worried about.


    Chen Xin didn''t think of the strict management in Hubei Province, but considering the importance of the three towns, many important materials in Hunan Province were sent from the three towns, which is understandable for the strict management in Hubei Province.


    However, under such circumstances, whether the identities of the three astronauts should be revealed is still a concern for Chen Xin.


    To show one''s identity, under the strict management of Hubei Province, and with the help of the local municipal government, one can go to the three towns better. Of course, this is advantageous.


    However, when Chen Xin and Zhang Chengguang discussed with each other before, they all hoped that more would be better than less. After all, they didn''t know what trouble would be caused if their identities were exposed.


    The data they are carrying is very important. The three astronauts do not want any accident. Although these data are useless to ordinary people except scientists, their identity as astronauts, especially those who are going to carry out the rescue plan, is too sensitive.


    No one can guarantee that there will be people who resent that they didn''t finish the task at the beginning and blame them for the meteorite impact.


    After all, even the three astronauts themselves feel that this is their responsibility and that they have not completed the task. It is hard to say that no one would not think so.


    After thinking about it for a while, Chen Xin said to the three astronauts, "I suggest that you don''t show your identity for the time being. Later, if you lend me your clothes, you will say that the space agency is carrying out the mission. We will go to the three towns directly after we have got the pass, and don''t cause more trouble."


    As for Chen Xin''s decision, Zhang Chengguang agreed after a little thought. Although it is not appropriate for Chen Xin to pretend to be a member of the space administration, it is also acceptable to act in a hurry.


    As for the fact that they are wearing astronaut''s regular clothes, it is difficult for ordinary people to distinguish whether these clothes are the uniform of the space agency or not.


    After discussing the solution to the problem, Zhang Yao, who is close to Chen Xin in figure, takes off his astronaut''s regular clothes and gives them to Chen Xin to put on. Chen Xin, who has changed his clothes, drives to the refuge where Xianning municipal government is located according to the guidance of the people in the inspection station just now.


    It seems that Xianning municipal government is not surprised that there are outsiders to apply for the pass. In addition, Chen Xin is playing the flag of the space agency, so they dare not delay. After registering the necessary information, they quickly get the pass for Chen Xin.


    With the pass, Chen Xin''s way to the three towns is naturally unimpeded.


    Back at the checkpoint again, after checking the fresh pass of Chen, the inspectors let them go.


    After moving on, Zhao Wu didn''t quite understand and asked, "can this kind of inspection really find out anything? And this checkpoint is not the only way, is it? Isn''t it hard to get around from other places? "


    "It''s not difficult to go around, so they didn''t check very strictly. After all, if you are willing to go here, it means that you have no ghost in your heart. Just check whether you have a pass or not." Chen Xin explained that he didn''t think it was incomprehensible: "besides, people have also said that there are still several inspections ahead, and those should be the places with strict inspection. After all, this is only the intersection of Xianning City, and that is the place to enter the three towns."

 Chapter 222

    Indeed, as Chen Xin expected, they moved all the way to the three towns, and both inspection and defense became tight.


    The first checkpoint was set up at the highway toll stations in the past. Although Yanguo has already cancelled the charges of ordinary national and provincial highways, the toll stations built in those years have not been completely demolished. Now they are just in use.


    Compared with the inspection station in Xianning, the inspection here is much more rigorous. It''s not the ordinary inspectors, but the police. Even Chen Xin unexpectedly saw a police dog wrapped in a thick cotton padded coat.


    This is the only living animal Chen Xin has seen in the past six months, except for bread worms, fish and mice.


    Although he didn''t like cats and dogs, Chen Xin had the impulse to roll the dog when he saw the police dog.


    However, police dogs are police dogs in the end. They don''t act like coquetry. As soon as they get on Chen Xin''s car, they start sniffing everywhere, searching for any suspicious dangerous goods or contraband.


    However, Chen Xin''s car is clean. The only problem may be Zhang Chengguang''s pistol.


    However, the space agency brand is really easy to use. Although the police on board the car are very strict, they are still very polite after knowing that they are from the space agency, and even take the initiative to ask if they need help.


    Chen Xin and Zhang Chengguang had already discussed it before, so naturally they declined the police''s help.


    After they had checked the vehicles, Chen Xin drove on to the three towns.


    In fact, in terms of administrative divisions, they have entered the scope of the three towns, but now they are still in the outskirts of the three towns, and they have not entered the urban area.


    As the only mega city in the central region of Yanguo, the three towns are also the central cities in the central region of Yanguo, and the area under their jurisdiction is also very vast.


    In fact, even the name of the three towns comes from the fact that the central area of the city is composed of three important towns.


    The three important towns themselves are geographical divisions formed by the division of the Yangtze River and the Han River. In the past, they were always three cities. It was not until the establishment of the Yan state that the administrative divisions of the three cities were aggregated together with the development of the times and became today''s three towns.


    Because of its well-developed land and water transportation, the city has been known as the "thoroughfare of nine provinces" since ancient times. It is one of the four cities in the world and the most important water, land and air transportation hub in Central China.


    At the same time, the three towns are also the headquarters of the joint logistics support force of Yanguo army, the core city of the Yangtze River economic belt, the strategic fulcrum of the rise of central China, and the comprehensive innovation and reform experimental area. They are one of the three intelligence intensive areas in China, and are also the national central cities.


    It can be said that it is precisely because of the three towns in the central region that Yanguo is able to maintain its control over the central region after the doomsday disaster and ensure the material supply and logistics support of the central provinces and cities.


    All these undoubtedly make the three towns different from other cities.


    Compared with the city where Chen Xin lives, the roads in the three towns are obviously much busier. Vehicles can be seen on the streets from time to time, and the snow on the roads has been cleaned to a certain extent. In addition, the checkpoints set up along the way, if it were not for the dark sky, the ruins like city on the ground and the craters that appear from time to time, Chen Xin really thought it was just winter The three towns of the season.


    But it''s clear that, whether it''s more stringent inspection, or the dark city, it''s the end of the world.


    However, the atmosphere of the three towns is obviously different. In other words, the city is more dynamic and more dynamic.


    Although Chen Xin''s city is also trying to recover from the disaster, the atmosphere in the city is closer to the feeling of struggling to survive in the last days.


    But the three towns are different. Although the ruins and snow are still visible in the process of approaching the urban area from the suburbs, the closer to the urban area, the more vitality the city exudes.


    Some buildings that are obviously under construction, the vehicles that come and go on the road, and even the scattered lights on the roadside all indicate that the city is being reborn.


    Maybe this is the difference between big cities and small cities. After all, this is the most important city in the central part of Yanguo. It''s not unusual that reconstruction has begun here.


    Just looking at the roadside building under construction, Chen Xin''s expression is a little strange.


    Zhang Yao noticed his change and asked curiously, "what''s the matter? Is that a problem? "


    "No, I just think it''s a little early to start rebuilding the city now?" Chen Xin raised his finger to a building ruins outside the car window, which was obviously collapsed by meteorites. He said to Zhang Yao, "you came down from the sky. It should be very clear that there are still a lot of meteorite debris in the sky. Now we start to rebuild the city. What if there are still stones falling down?"


    Hearing what Chen Xin said, Zhang Yao thought of the impacts he had suffered when he came down from space in the re-entry capsule, and he could not help nodding his approval.


    However, although he agrees with Chen Xin''s view, on the other hand, he does not fail to understand why the post disaster reconstruction of the three towns has started now: "however, it is not difficult to understand that it is a matter of probability to start the post disaster reconstruction now. After all, it is impossible to put the post disaster reconstruction work on hold because of a certain degree of danger Do it?It may take a little risk to start the post disaster reconstruction now, but compared with the delay of the overall progress and the delay in the production of various materials, this risk can still be tolerated. After all, most of the debris that can fall down now are small pieces of meteorite debris. Many of them burn up before they fall to the ground, and the volume that can fall down is not large. At most, just smash a pit and fill it up. "


    Zhang Yao''s words left Chen Xin speechless, but he had to admit that Zhang Yao was right.


    It is a good thing for the country and the common people to be able to resume production earlier in this eschatological environment.


    After all, the disaster caused by the previous meteorite impact caused serious damage to the original industrial system. The chemical plants around Chen Xin''s city were basically destroyed, and the whole city had only a little industrial production capacity preserved in the underground factory area.


    This is true for a city, especially for a country. Although the country will retain part of its industrial production capacity and restore part of its underground production, it is obviously unable to meet the needs of the whole country.


    It''s just like the case of the oxygen generator in the official refuge before. If it''s before the disaster, how can there be a shortage of equipment?


    With the industrial production capacity before the disaster in Yanguo, under the condition of intervention at the national level, not to mention meeting the domestic demand for use, there is even spare power to export to foreign countries to receive foreign trade orders.


    Therefore, the resumption of production should also be the first consideration of Yanguo''s senior management.


    As for the possible losses, it is obvious that we have to make a choice at this time.


    When Chen Xin was thinking about this problem, they had gradually entered the three towns. Instead, there were fewer cars to be seen on the road. It seemed as if trucks were not allowed to enter the city as before the disaster.


    And relatively, although the city is also in the process of debris clearance work, but there are not so many construction sites outside the city.


    It seems that the three towns first cleaned up the suburban areas, restored the industrial production, and then considered the internal reconstruction of the city.


    From the outskirts of the city to the city, Chen Xin encountered a new checkpoint. This time, the inspection was more detailed. Even the whole car needed a scanner to scan the car body.


    Under the careful scanning, Chen Xin''s car was inevitably stopped.


    "Hello comrade, we need to check your car. There is a place on your car that can''t be scanned. Can you open it for us to have a look?" After getting on the bus, the people at the checkpoint asked Chen Xin directly.


    As soon as Chen Xin heard it, he understood what the other side was saying, but he hesitated to open it for the other side to see, because what the other side was saying was the power source of the car, where the three isotope thermoelectric batteries were installed.


    Because the thermal energy of the isotope thermoelectric battery is generated by the radiation released by isotope decay, for the sake of safety, metal lead is used in both the three batteries and the installation slot of the battery.


    This not only insulates the radiation, but also prevents the scanner from working.


    However, seeing Chen''s hesitation, the people at the checkpoint were obviously nervous, thinking that there was something shady on Chen''s new car.


    Not only the inspectors who got on the bus, but also the staff in the inspection station came out with guns and fell down the roadblocks of the inspection station, obviously preventing possible emergencies.


    This makes Zhang Chengguang on one side nervous. They quickly look at Chen Xin and ask him if he needs their help. After all, if they show their identity, they can help Chen Xin cover up the past in the name of the space agency.


    Chen Xin motioned for the three to be calm, and said to the inspectors: "this comrade, we belong to the space agency. Some things on this car are secrets of the space agency. It''s not impossible for you to read them, but they must be kept secret. And you can check them by two people at most. Do you think it''s ok?"


    After hearing Chen Xin say so, and the clothes of the three astronauts next to him are indeed printed with the words of Yanguo aerospace, the inspectors agreed to Chen Xin''s request after a discussion.


    When Chen Xin saw this, he took two inspectors to the cab and opened a cover plate of the connecting part between the cab and the life cabin, revealing the three batteries installed inside.


    "What you can''t scan out should be this part. The structure of this part is lead, and the three above are isotope thermoelectric batteries, which are used for power generation. Because of certain radiation, they are sealed with lead." Chen Xin indicated to the two inspectors that after they had seen it, they would cover the cover again.


    After checking, the inspectors did not find any problems, so they did not say anything more. Under Chen Xin''s advice, they agreed to keep it secret, so they got out of the car.


    But when the inspectors got off the train, the three astronauts looked at Chen Xin with strange eyes.


    Zhang Chengguang couldn''t help asking Chen Xin, "Chen Xin, who are you? Isotope thermoelectric battery is not something that ordinary people can get! "


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 223

    "Isotope thermoelectric cells are not very complicated, are they? As long as you can get radioactive elements with a long half-life and get a few thermoelectric chips, it''s not difficult to make such a thing yourself! " Facing Zhang Chengguang''s inquiry, Chen Xin showed a very indifferent attitude, hoping to muddle the matter.


    Looking at Chen Xin''s indifferent attitude, Zhang Chengguang feels awkward and helpless.


    The principle of isotope thermoelectric battery is very simple. To put it bluntly, it is thermoelectric conversion. A primary school student can give you materials and explain the principle clearly. But the problem is that radioactive elements are controlled materials in Yanguo and even all over the world. It''s hard for ordinary people to buy them and even see them.


    Even if Chen Xin had access to a piece of radioactive elements enough for his use, he also got a high-performance chip for thermoelectric power generation, and made such an isotope thermoelectric battery. But this kind of thing can be used to light an electric lamp or make a heater at most. It''s impossible to drive an armored tracked RV with a weight of at least ten tons!


    Zhang Chengguang is an astronaut. He has also had contact and understanding with isotope thermoelectric battery. In the aerospace field, this kind of battery has a wide range of applications. After all, it is a battery that can output electricity for a long time. It can be used on both satellites and detectors.


    But even the Yanguo space agency, regardless of the cost, may not be able to make an isotope thermoelectric battery that can drive Chen Xin''s car.


    Zhang Chengguang himself has driven this car these days. He clearly knows how good the power performance of this car is. Besides the good engine, he also needs a heart with strong output.


    It''s amazing that even three isotope thermoelectric cells can achieve the output power of at least 100kW. If this kind of cell can be used on Yanguo''s spacecraft, the solar panels can be thrown into the garbage.


    Moreover, in today''s eschatological environment, this kind of isotope thermoelectric battery with strong output has broad prospects and wide applications.


    Even before the disaster, the energy problem has always been a problem that plagues and restricts the development of all countries. The traditional fossil energy is drying up, and the pollution is serious, but the development of clean new energy is not so fast. The problem of energy shortage has always been a heart disease of blue star countries.


    Especially for Yanguo, a developing country, the energy problem is even more serious, which seriously restricts the country''s development speed.


    When the end comes, the energy problem becomes more serious.


    But Chen''s isotope thermoelectric battery is a good way to solve many problems. Whether it''s used to power a small shelter, to power a car, or to use it for other purposes, this kind of isotope thermoelectric battery, which looks small but has a very strong output power, is too widely used!


    Zhang Chengguang even came up with at least ten or twenty places where he could use this kind of isotope thermoelectric battery after a little thought.


    But now the problem is that in Zhang Chengguang''s view, the strategic materials that can change Yanguo''s existing energy structure are Chen Xin''s personal things. He even said that he made them himself, and even the technology is in Chen Xin''s hands.


    Zhang Chengguang is dubious about Chen Xin''s claim that he did it himself.


    The letter comes from the advanced technology of isotope thermoelectric battery used by Chen Xin, which is beyond the reach of scientific research institutions in Yanguo at present. No matter how smart Chen Xin is, he is unlikely to buy this kind of battery from other places. He can only make it by himself.


    The reason for the doubt is that Zhang Chengguang has not seen Chen Xin''s hands-on ability, and some doubt whether these isotope thermoelectric batteries are Chen Xin''s own.


    After all, it is impossible to surpass the vast majority of scientists and achieve the things that these scientists have spent countless resources and time on, unless they are the kind of genius who can really change the whole world by themselves.


    However, after hesitating and hesitating for a while, Zhang Chengguang still didn''t ask Chen Xin any more. He just asked: "Chen Xin, the technology for manufacturing this kind of battery, do you mind selling it to the state? Or selling finished products is OK! "


    Hearing Zhang Chengguang''s question, Chen Xin didn''t answer immediately, but appeared to be hesitant and hesitant.


    Seeing Chen Xin''s hesitation, Zhang Chengguang, though very urgent in his heart, still restrained his emotions and took the initiative to say: "you may not be able to make a decision on this matter for a while, so it''s better to think about it more. However, I still hope you can at least provide the country with finished isotope thermoelectric batteries. After all, this can provide great help for the country''s post disaster reconstruction ¡£¡±


    "I''ll think about it." Chen Xin did not say much, but nodded to Zhang Chengguang.


    after Chen Xin promised Zhang Chengguang that he would consider selling the technology or finished product of isotope thermoelectric battery to the state, neither side mentioned it again.


    Chen Xin''s car, driven by Zhang Yao, finally drove along the road into the downtown area of the three towns.


    On the way, they also met two other checkpoints, which also strictly inspected Chen Xin''s car.After passing through these checkpoints, Zhang Yao, while controlling the steering wheel and following the guidance of the staff of the checkpoint, drove to the seat of the provincial capital of Hubei Province, which is located in three towns, also asked Chen Xin, "Comrade Chen, what did you do before? Do you know a lot about mechanics, such as refitting cars, making your own planting boxes, and this isotope thermoelectric battery? "


    "I don''t know much about it, but I''ve been influenced by my father since I was a child, and I''ve been engaged in this work since then. I have accumulated a little bit." Chen Xin smiles and answers with some disappointment.


    Zhang Yao recognized Chen Xin''s melancholy. Knowing the purpose of Chen Xin''s trip, he also understood the emotion, so he comforted him: "Comrade Chen, you don''t have to be too melancholy. You will be able to reunite with your parents. Everything will be fine."


    "Thank you first, brother Zhang. Everything will be fine." When Chen Xin heard Zhang Yao''s consolation, he burst into laughter.


    However, while comforting Chen Xin, Zhang Yao also said curiously, "Comrade Chen, your father is very powerful. Just a little edification can make you so young and promising. I believe your father must be a great man. I really want to get to know him."


    "Ha ha, brother Zhang, if you want to know my father, you''ll have to wait for me to pick him up, and you''ll be able to see him when you go back through three towns." For this problem, Chen Xin can''t help joking: "but the prerequisite is that brother Zhang, you were still in Sanzhen at that time."

 Chapter 224

    It is not hard for Chen Xin to hand over the technology of manufacturing isotope thermoelectric battery to the state.


    Of course, he knows how good isotope thermoelectric batteries are for the country and what role they can play in post disaster reconstruction.


    Just imagine that a small isotope thermoelectric battery can achieve hundreds of kilowatts of power output. If the technology is applied to small nuclear reactors to improve the output power of small nuclear reactors, how amazing the effect will be.


    It can be said that if the technology of manufacturing isotope thermoelectric battery can be thoroughly understood and extended, it will be enough to change the current situation of energy application in China, change the energy structure system of the whole country, and even affect the development strategy and situation of the whole country!


    Even before the disaster, this is enough to change a country''s core strategic technology.


    Although Chen Xin is not the kind of person who can give everything to the country for free, he does not want to say that he has such technology in his hands and still wants to hide it in his own hands. He is not willing to help the country for his own interests.


    But the problem is that although he made the isotope thermoelectric battery on novice Chen himself, it is something that can only be made by relying on the system. It is not something that he can understand the technical principle, explain clearly, or reproduce without the system.


    In other words, Chen Xin can make finished products and improve them to make them more powerful, but he can''t tell how to make them and what principle they are based on.


    What he can sell to the country is only the finished products of isotope thermoelectric battery, but not the related technology.


    This is the fundamental reason for his hesitation and hesitation, because he does not provide technology, but only provides finished products. In some ways, Chen Xin is not willing to provide technology.


    Maybe you can provide the drawings yourself? Chen Xin scratched his head, but he had a new idea.


    His workbench can record the drawings of the items he made, so he can record the drawings of the isotope thermoelectric battery, and then provide the finished products and drawings for those scientists to carry out reverse research. In this way, a lot of things can be saved.


    As for the related technology, this is really not available. We can only rely on those scientists to do reverse cracking.


    After thinking about it, Chen Xin was much more relaxed, and aware of the change in his mood, Zhang Chengguang and the other two astronauts could not help feeling a little more expectation and hope.


    Although Chen Xin did not agree or express anything, Zhang Chengguang still can see that Chen Xin has made a decision on his proposal.


    Driving by Zhang Yao, Chen Xin''s car arrived at the capital of Hubei Province.


    The astronauts'' affairs are too important. In the current environment, they can only contact a provincial government to ensure the security of the important data in their data storage.


    For the arrival of the astronauts, as well as the important data they carry, Hubei provincial government also attaches great importance to it after being surprised.


    However, the provincial government does not have the ability to process these data, so after meeting the three astronauts, the high level of Hubei Province sent armed police to escort them to the optical valley of the three towns.


    The three astronauts did not object to the decision of Hubei provincial government.


    The provincial government is an administrative organ, so it is impossible to deal with this kind of data related to scientific research, but the optical valley is different.


    This is an important high-tech industrial zone in Central China. Before the disaster, there were more than 40 universities and more than 50 national and senior government research institutes. In addition, there is the largest and most complex underground complex in Asia, the underground city of Optics Valley.


    For the underground city of Optics Valley, Chen Xin only learned about this underground city, which is known as the largest single underground building structure in the world, from the TV program, and has not really been here.


    However, when Chen Xin drove down to this place under the escort of two armed police armored vehicles, he was obviously surprised by the huge underground building.


    "Why did you build such a big underground city here? Is it for disaster prevention? " Driving slowly into this huge underground city, Chen Xin is quite surprised to ask the staff sent by Hubei provincial government about the original purpose of building here.


    The optical valley underground city is a huge disc-shaped building. Just looking from the entrance, you can feel the huge internal space, just like the terminal of a large airport.


    This also makes Chen Xin very curious. Why did the high-rise buildings of the three towns and Hubei province build such exaggerated buildings in the central area of the city, especially underground.


    "It''s so big here, but it''s mainly for practical use." Of course, the staff of Hubei provincial government have a deep understanding of this huge underground city. After all, it was not only the largest underground complex in Asia in the past, but also the largest underground refuge in Hubei Province, or the underground city worthy of the name.


    "Usage requirements?" Chen Xin is more and more curious about what kind of use needs to build such a large underground building: "is this a subway station? But the subway station doesn''t have to be this big, does it? "As for Chen Xin''s conjecture, the staff explained with a smile: "the underground optical valley was the most congested intersection in the three towns five years ago. At that time, the municipal government wanted to improve the traffic so as to speed up the development of Optical Valley, so it planned such an underground complex to be used as an underground transportation hub.


    Here, the three metro lines and two highways of the three towns converge here. During the peak period, 80000 people need to pass through each hour. If we don''t build a large site, we can''t accommodate so many people, and we can''t meet such a large traffic demand. "


    After listening to the staff''s introduction, Chen Xin realized that this huge underground city was not the underground shopping mall or simple underground building he had originally thought of, but a transportation hub or a huge subway station.


    Chen Xin believes that when it was first built, those engineers must have spent countless efforts here to build it to meet all the needs of use, and at the same time, it was spacious, bright and beautiful.


    But now, this once beautiful underground complex has been transformed into a huge underground city.


    The top of the whole complex has been reconstructed and reinforced. The glass structure which could let sunlight into the interior of the complex has been obviously sealed, which not only plays a protective role, but also provides thermal insulation.


    And when Chen Xin looked up at a subway line crossing the complex, a train just entered the platform.


    "The traffic lines here are still in operation. Although the number of subway trains is not as dense as before, they are still in operation. However, many platforms along the subway have been transformed into underground shelters, and their supplies depend on the subway." See Chen Xin looking at the train, the staff also rushed to introduce.


    Chen Xin was not surprised at this. He just asked the staff, "are all the scientific research institutions concentrated here now?"


    "So far, the schools and scientific research institutions of optical valley are still in their original positions, because they actually have underground bunkers or underground parking lots and civil air defense projects, so the scientific research institutions basically just abandoned part of the buildings on the ground and transferred the research facilities to the underground." It seems that the staff talked about Chen Xinhui''s problems, guiding Chen Xin''s way through the complex. At the same time, they also introduced the situation here: "various scientific research institutions and schools have been transferred to the underground, and the three town government has dug underground passages connecting these scientific research institutions and schools, connecting the whole optical valley area. The core is here.


    It can be said that the whole optical valley area is an underground city worthy of the name. What we are now in is just the core part of this underground city. The research institute you are going to is not far from here. In the past, it was only five minutes'' walk. "


    According to the instructions of the staff, Chen Xin turned the car into a tunnel, followed by two armed police armored vehicles.


    This kind of configuration looks a little scary, but people on the side of the road see three armored cars passing by, but they don''t say anything about it. It seems that it''s common.


    After driving into the tunnel, Chen Xin continued to ask, "it seems that I didn''t see any residents just now. Aren''t there many survivors here?"


    "Before the disaster, there were 400000 students and more than one million permanent residents in the optical valley area. After the disaster, there were more than 100000 students stranded and more than 800000 other survivors. How can there not be many people?" The staff showed a wry smile, but he still answered Chen Xin''s question: "it''s just that the optical valley complex is not used to accommodate a large number of people. It is mainly used as a transportation hub and regional center, and the surviving population is mainly distributed in other underground shelters in this area."


    Such a large underground space has not been transformed into a living space? Chen Xin was very surprised. Even the three astronauts in the car were puzzled. It is reasonable to say that if the underground space as large as the optical valley complex is transformed into a living space, there will be no problem for tens of thousands of people to survive.


    After all, according to the staff''s introduction just now, the whole underground complex of Optical Valley covers an area almost as large as 32 football fields, and it''s not hard to live in tens of thousands of people.


    However, facing the questions raised by Chen Xin, the staff still had to smile bitterly: "the underground complex of Optical Valley is mainly used as a transportation hub. Although the underground public space is huge, it is very transparent. In this kind of environment, even if we have transformed and closed the entrances and exits, because the internal space is too large, it is still difficult to keep warm, so we should simply stay here There will be no residents, but will be used as a material distribution center. "

 Chapter 225

    Chen Xin''s car, escorted by two armed police armored vehicles, finally drove into a branch of the underground tunnel, passed through two gates with sentries, and stopped in a parking lot.


    "This is a state-level scientific research unit in Sanzhen, which is responsible for computer research. There is a large-scale computer that can process the data you bring back. At present, it is also connected with other places in the country that can access the network, and the National Space Administration is also in it. After the data is uploaded here, it can directly share the data with the National Space Administration. ¡±After everyone got off the train, the staff of Hubei provincial government introduced Chen Xin and the three astronauts here.


    When the staff member introduced them, people from the scientific research unit also welcomed them and took them in.


    After entering the scientific research unit, Zhang Chengguang did not delay, but directly took the data storage which was reloaded in a suitcase to upload data with the people of the scientific research unit. Chen Xinze and two other astronauts, accompanied by the staff of Hubei provincial government, attended the national scientific research unit.


    The whole scientific research units are now underground, because most of the above ground parts are seriously damaged by the previous meteorite impact. Even if they are still intact, most of them can no longer be used as scientific research laboratories.


    Nowadays, most of these ground buildings are used as dormitories and office areas for some staff after cleaning and repairing, and important research facilities are placed underground.


    However, even so, the research atmosphere of the whole scientific research unit has not been affected. It can even be said that because of the disaster, the researchers here are more devoted and enthusiastic to their work.


    "Due to the influence of doomsday, many original scientific research projects have been cut down. Now our main research direction is how to restore the network system, so that all parts of the country can realize network connection again. At present, our main research direction is wireless signal transmission, and the idea is to use the signal base stations set up in various cities as transit and transceiver terminals." Chen Xin and two astronauts were briefed by a researcher in a white coat on their ongoing scientific research projects.


    Chen Xin naturally can see that they mainly introduce the two astronauts. He just comes by, but this kind of treatment is no accident or dissatisfaction for Chen Xin. Anyway, it''s a visit for nothing. Just listen to it.


    Chen Xin doesn''t feel much about the scientific research and project research, because for him, it''s just a matter of upgrading the system.


    Whether he can do it or not depends on whether Chen Xin has such an idea in his mind and whether he has enough survival.


    Of course, Chen Xin has great admiration and respect for the spirit of scientific researchers'' hard work. He is just an ordinary person with golden fingers, which is different from those who really rely on their own efforts to change the world.


    However, out of respect for these researchers, and out of the hope that the current situation in Yanguo can be improved, and more importantly, in the hope that the network can be restored, Chen Xin took the initiative to ask, "do you have any achievements now? I''ve heard that you''re still connected to other places. Is it through the device you''re studying? "


    Chen Xin''s inquiry aroused the interest of the researchers. He smiles and nods: "yes, this is a military project that we were originally studying. It was originally used to maintain network communication when the army was fighting in the field, but this project used to transmit signals through base stations and satellites. Now we can''t connect satellites. We can only use base stations for signal transmission It''s time to build a simple transmission network. "


    Hearing what the researcher said, Chen Xin said: "that is to say, if there is a base station, it can still recover the wireless network signal of a region?"


    "That''s true, but without our access equipment, we can''t access the network, and all signals must be transferred through the base station. Considering the current bandwidth of the base station, we still can''t provide civil services." This researcher can naturally understand what Chen Xin means by restoring the wireless network signal in a region, but he is not optimistic about the civilian application of this technology.


    With Chen Xin, two astronauts and the accompanying provincial government staff, we walked into a room for exhibition. A set of wireless network access equipment and a small base station were placed on the table.


    "This is what we''ve developed." The researchers showed Chen Xin and the two astronauts the equipment on their desks that looked like two big boxes: "this set of base stations with large antennas can cover an area with a radius of 50 kilometers. Within this area, as long as you use this set of access equipment, you can realize network access and signal transmission within the signal range. If this base station can connect to satellites or more A large base station can realize signal transmission in more areas and more devices. "


    Chen Xin looks at these two devices. On the surface, he is still interested in the devices, but in fact, he has called out the system interface.


    "Wireless signal access equipment transmission base station"


    "upgrade scheme 1: the coverage area of transmission base station is increased, the signal of access equipment is enhanced, the stability of signal transmission is increased, and the survival point required for upgrade is 1500"


    "upgrade scheme 2: the volume of access equipment transmission base station is reduced, the battery storage capacity is increased, the energy consumption is reduced, the confidentiality is enhanced, and the survival point required for upgrade is 1100"Seeing that the system is still able to use these two devices normally, Chen Xin smiles and looks up at the researchers: "can I have a look at these two devices? Is it developed for military use? "


    "Yes, it''s a military prototype. We''re still improving it, but we haven''t finalized it. As for the fact that we can establish signal connection with other places, it''s because we have a large base station and transmitting antenna on our head, which can transmit signals What are you doing! " The researchers are still introducing the situation, but they are suddenly shocked by Chen Xin''s action and rush to stop him.


    In the eyes of the researcher and other people in the room, after Chen Xin put his hand on the equipment, he took it apart and fiddled with it.


    After the researchers stopped Chen Xin, his hand left the equipment, but the equipment he touched was obviously different.


    "On the spur of the moment, I thought it could be improved, so I started it directly. I''m sorry!" Chen Xinchong apologized. Although he didn''t know what he had done in their eyes, he still explained to the researchers: "I adjusted the signal transmission strength of the equipment and the coverage area of the base station. Their performance should be improved. Unfortunately, the materials are not very good. Otherwise, I should be able to reduce their size and improve the battery life and signal quality "The confidentiality of the contract."


    When he heard Chen Xin''s words, the researcher''s first reaction was that he didn''t believe them. However, looking at Chen Xinyan''s chiseling appearance, he hesitated for a moment, and still called someone to inspect the two devices.


    And Chen Xin three people also cannot continue to visit naturally, but was invited to a room to stay temporarily.


    "Comrade Chen, do you really improve the performance of the equipment by fiddling with it?" Zhang Yao still didn''t believe it and asked Chen Xin in a low voice.


    Chen Xin nodded, his face was full of confidence, but what he was confident about was not his own technology, but the upgrade function of the system.


    Seeing Chen Xin like this, Zhang Yao didn''t say much. He looked at Zhao Wu and then calmed down.


    It''s not a big deal. After all, the equipment itself is for display. If it''s damaged, it won''t be a big problem. This is also the place where the equipment is researched and developed. If it''s damaged, it can be repaired.


    Moreover, if the equipment is damaged by such manipulation, it can only prove that the quality of the equipment is not good.


    So on the whole, it''s not a big deal.


    However, it is not a small matter to say that it is small, because Chen Xin''s manipulation has improved the performance of the equipment, which is undoubtedly not a small matter for these researchers.


    Because they are trying every means to improve the performance of the equipment day and night, but many researchers are trying their best to improve the performance bit by bit. Chen Xin just raised his hand and played with it, which is undoubtedly a very difficult thing to accept.


    Of course, compared with the improvement of equipment performance itself, whether the scientific researchers can accept it has become insignificant. After all, the most important thing is that the new equipment can be improved, and how Chen Xin did it is the real focus.


    "How on earth did you do it?" Just now, the scientific researchers went back and forth, holding a test result in their hands, and their faces were crazy and confused: "the coverage area of the base station has been increased by 30%, the signal transmission strength has been increased by 40%, and the stability has been significantly enhanced. How can we do this? I don''t see where you''re moving! "


    "It''s just a small skill that can improve the new capability of the equipment. You can compare my adjusted equipment with your original equipment and adjust the original equipment according to the differences." Chen Xin can''t explain where he moved, so he can only be so vague.


    However, researchers obviously can''t accept such a saying. For these researchers, when they come across a problem, they must find out what''s going on, especially when Chen Xin gives the answer but doesn''t give the problem-solving process. This is undoubtedly the most maddening and intolerable thing for researchers.


    However, Chen Xin didn''t know how to answer, which led to Chen Xin''s ambiguity and refused to answer his questions.


    Just as the two men were constantly entangled, Zhang Chengguang finally completed the data transmission and reunited with them. Chen Xin finally got rid of the entangled scientific researcher and left the scientific research institute with the three astronauts.

 Chapter 226

    After leaving the scientific research unit, Chen Xin should have parted ways with the three astronauts.


    After all, he had nothing to do with the three astronauts. He promised to send them to three towns, and Chen Xin did.


    Now that things are almost done, it''s time for Chen Xin to start his journey again, crossing the Yangtze River from three towns, and then going to Anhui Province.


    However, for Zhang Chengguang and the other two astronauts, letting Chen Xin go is the biggest loss.


    This loss refers not only to themselves, but also to the whole country.


    If it had not been for what happened in scientific research institutions, they might not have realized this.


    However, when they saw that Chen Xin could improve the performance of the device by just playing with his hand, they clearly realized that Chen Xin was a genius, and they became convinced that he could make isotope thermoelectric batteries.


    As a result, Chen Xin''s value in the eyes of the three astronauts is rising.


    Although Chen Xin intends to leave as soon as possible, the three astronauts hope to retain him as much as possible.


    However, although Chen Xin understood the three astronauts'' intention to retain themselves and their importance in their eyes, Chen Xin also understood that he was powerful only by relying on the system. It was totally impossible for him to explain those technical principles. He could only provide finished products, but could not provide technology.


    After all, although the system can upgrade anything that Chen Xin can see, it does not allow the system to provide technology.


    As for the technology of parsing system upgrade Even if you can''t see the system upgrade, how can you analyze the technology it uses?


    So we can only deduce the technology on the finished product according to the finished product provided by the system.


    However, one of Chen Xin''s purposes is to make the country pay more attention to itself, and take the opportunity to provide some upgraded products to help the country''s post disaster reconstruction. At the same time, he also takes the opportunity to reap a wave of survival.


    So after politely refusing the three astronauts to stay, Chen Xin also took the initiative to open the battery compartment cover of his car, removed an isotope temperature difference battery from the battery compartment and handed it to Zhang Chengguang.


    "I understand what you mean, but there are some things that I only know how to do, and I don''t know why, let alone how to say." Chen Xin, with a helpless smile on his face, handed the battery to Zhang Chengguang and said, "you can use this battery to find someone to do reverse cracking research. Afterwards, if you need, when I come back from Anhui Province, you can also go to Hunan Province to find me the drawing of the battery. I can even show you how I made it, but you want me to explain what I mean What can be done, and what principles I use to do it, is really embarrassing for me. "


    Chen Xin''s explanation was obviously unacceptable to the three astronauts, but his attitude was already very sincere, and the three astronauts could not force anything more.


    But Zhao Wu was still a little reluctant to believe and muttered: "I know how to do it, but I can''t explain the principle clearly. How did you design it?"


    This makes Chen Xin speechless. Indeed, if he only makes drawings, he will know how to do it and why.


    But since Chen Xin is a designer, he should know the design principle. Otherwise, how can he know how to make things? It''s not an original tool. You can make mistakes step by step with your experience.


    In the face of this kind of questioning, Chen Xin can only say with a wry smile: "I can''t explain this. It''s just like some people who fall on their heads and become proficient in five foreign languages. I just know how to do it, but I can''t explain to you why I want to do it."


    It''s not something made up by Chen Xin, but a real case.


    And this case is not isolated, there are about dozens of such people around the world, they are collectively known as acquired scholar syndrome.


    Chen Xin discovered the existence of this magical disease just because he wrote books and searched for information. Now it''s just right to use it as an excuse to cover up his own peculiarity.


    After all, even before the disaster, no one could explain clearly how the magical thing of acquired scholar syndrome happened. Therefore, Chen Xin said that he suddenly awakened his mechanical ability or something, and no one could raise a favorable question.


    Sure enough, after hearing Chen Xin say so, Zhang Chengguang also completely gave up the idea of continuing to ask Chen Xin, can only reluctantly accept Chen Xin''s explanation.


    "Whatever the reason, Chen Xin, it''s good that you are willing to contribute to the country." Zhang Chengguang handed the isotope thermoelectric battery in his hand to Zhao Wu, and said to Chen Xinyu: "I know that people of your generation often say that the state expropriates private things, and people with special performance will be arrested for research or slicing, but these words are just deceiving children. Yanguo is not a federation, and it will not be so chaotic."


    After that, Zhang Chengguang smiles at Chen Xin and leaves Chen Xin''s car with two companions.


    Seeing Zhang Chengguang and the other two astronauts leave, Chen Xin can''t help but smile and shake his head. In fact, he doesn''t have the ideas Zhang Chengguang said.As an Internet writer, he even knows more about conspiracy theories than Zhang Chengguang, but in fact he doesn''t think the country will really do so dark.


    Chen Xin starts the protection mode of the vehicle and is ready to take a bath. He has a good rest tonight and will continue his journey after crossing the river tomorrow.


    Because it was in the parking lot arranged by the Hubei provincial government, Chen Xin just parked his car in a parking space and did not put down the hoe under the car body.


    Originally, the staff of Hubei provincial government arranged accommodation for Chen Xin, but considering the current accommodation conditions, he still chose to sleep in his own car.


    When Zhang Chengguang and his wife were in the car, Chen Xin asked them to go to bed. However, they were obviously embarrassed to sleep in Chen Xin''s bed, so they chose the sofa in the living room. After the table was lowered down, they could make a double bed with the sofa. It was no problem to squeeze three people to sleep.


    Now that everyone is gone, the sofa on the car has naturally restored its original function.


    Take off the dirty clothes and throw them into the washing machine under the Liuli desk. Then take out the clean clothes from the wardrobe. Chen Xin goes into the bathroom and takes a bath.


    Chen Xin didn''t wash this bath for a long time. After all, although there is plenty of fresh water on the car and there is a filtering device for circulation, it can''t be too wasteful.


    However, thinking of this, Chen Xin secretly reminds himself that he should find a way to replenish the fresh water on the bus tomorrow and treat the sewage in the gray water tank and the black water tank by the way.


    In addition, there are three more people on the bus these days, and some food has been consumed. We should go to find a way to replenish it tomorrow.


    It''s just what you can supply yourself with Today, I gave Zhang Chengguang an isotope thermoelectric battery, which should be able to replace a large number of supplies, right?


    Although I have known Zhang Chengguang for only a few days, Chen Xin doesn''t think he is a mean person.


    Thinking about these things, Chen Xin took a bath and prepared to burn some hot water to drink, but there was a knock on the door outside the car.


    Chen Xin scratched his head and put on his clothes. Then he opened the door and found that the former staff member of Hubei provincial government was standing outside.


    "I''m sorry to disturb Comrade Chen Xin. You''ve had a rest. They said that you were short of supplies, so they sent some to you. Do you want to put them in the car or in the trunk?" There is also a car behind the worker, which is full of supplies.


    Colonel Zhang, of course, said that Zhang Chengguang, the astronauts of Yanguo are all active servicemen, and everyone is at least a military rank at the school level. Some of the astronauts who went to heaven before even carried generals later.


    Seeing the supply, Chen Xin scratched his head, but thanks the staff member for his kindness, and then opened his trunk.


    The staff sent quite a lot of supplies. In addition to the same kind of food that Chen Xin had brought to the shelter, there were some dehydrated vegetables and dried fruits, as well as a large box of processed dried meat and other food. These supplies were even more than the total amount of supplies Chen Xin had prepared before his departure.


    Chen Xin''s eyes widened and asked in surprise: "there are so many things. Is there no problem? What''s more, there are dried fruits and dried meat. Are there such abundant supplies in Hubei Province? "


    "There is no problem with these materials. Comrade Chen Xin, we still understand how important the things you give to Colonel Zhang are. These materials are just for compensation." The staff member always had a shallow smile on his face, which made people feel very good. When he explained, his tone was quite friendly: "our three towns are at least the core cities in the central region. There are a lot of strategic reserve materials stored here. If we don''t make do with time, we can prepare more abundant materials for you. Comrade Chen Xin, if you need anything else, I can help you to deploy it and try to bring it to you tomorrow morning. "


    Although this staff member talks about fighting for it, Chen Xin knows that as long as he talks, this staff member must be deployed overnight and delivered on time tomorrow morning.


    However, after thinking about it, Chen Xin said to the staff member, "I need two car batteries and some corresponding parts. Just now, I gave Colonel Zhang a battery. I''m missing one, so I can only make do with it by changing it to a car battery."


    After hearing Chen Xin''s request, the staff member''s eyes brightened obviously, wrote down Chen Xin''s request, and politely left, immediately began to contact the matter of material allocation, and informed the Hubei provincial government of the matter.


    Chen Xin doesn''t know that his request has made the staff take this matter as an important task to complete, but he can guess the consequences of his request. However, Chen Xin doesn''t care about it. Since he decides to show some things, there is no need to hide them.

 Chapter 227

    Sure enough, the next morning all the car batteries and related materials Chen Xin needed were delivered to him, along with an official from Hubei provincial government and several scientific researchers.


    Chen Xin didn''t object to the fact that these researchers set up the operating platform and set up the camera solemnly to record all his operations.


    In fact, he is also quite curious about what kind of picture will be presented if the system upgrade process is photographed with camera equipment.


    Is it a "reasonable" picture with self consistent logic, or a real picture with a flash of green light, or a "real" picture with fuzzy effect?


    This really makes Chen Xin curious.


    In particular, in the spirit of pragmatism and truth-seeking, and in order to prevent the possible failure of the equipment, these researchers not only set up a number of machines, but also got a variety of photographic equipment with different storage forms.


    There are large cameras for TV stations with tapes and small cameras with memory cards, and there are even staff with hand-held PTZ.


    What makes Chen Xin feel exaggerated in particular is that they even got a film machine for making movies.


    He was startled by the exaggeration of these people, but Chen Xin still acquiesced in their behavior, because he was really curious. Maybe the pictures recorded by different devices would be different.


    After a few polite words with the officials of Hubei provincial government, Chen Xin came to the work table arranged by the scientific researchers, and all kinds of materials he needed were already on the table.


    Chen Xin touched his chin, as if thinking about how to start, but in fact, he was just thinking about whether he wanted to rub the nuclear battery or not.


    In the final analysis, it is still a systematic matter to transform the automobile battery into an isotope thermoelectric battery, that is, the so-called "nuclear battery". For Chen xinlai, there is no question of whether the process is complex or whether the materials are fully prepared.


    Even if there are no radioactive elements in the materials Chen Xin asked for yesterday, he can "make" an isotopic thermoelectric battery that is completely reasonable in the eyes of these researchers by using these things in front of him.


    However, in order to avoid subverting the Three Outlooks of these researchers, or to say that they are not really regarded as monsters, Chen Xin thinks that he should be a bit clumsy and transform a battery that can meet the use needs. The upgrade of nuclear battery can be done after leaving three towns.


    However, after talking with the officials of Hubei Province, he gave up his idea and felt that he should not be clumsy.


    Because the meaning of this official''s words is to keep Chen Xin in the three towns. He even proposed that Hubei Province send someone to help Chen Xin pick up his parents and arrange accommodation for him in the three towns. A series of follow-up work units and welfare benefits are also easy to discuss.


    In a word, it is to win over Chen Xin with various conditions.


    Of course, the official did not use any coercion and inducement, and his attitude was amiable, and his identity was enough to make Chen Xin feel that Hubei Province attached great importance to him.


    But this is different from Chen Xin''s original plan.


    In Chen Xin''s prediction, he showed his ability to attract the attention of the government, and then cooperated with the government to help the country complete the post disaster reconstruction faster and better with his system black technology. All these steps Chen Xin expected were to deal with the national level, and also to carry out the whole plan in an equal and cooperative way.


    But now, according to the meaning of this Hubei provincial government official, Hubei Province itself wants to recruit Chen Xin. Although it attaches great importance to Chen Xin, it is more like recruiting talents than equal cooperation.


    This kind of thing is not unacceptable to Chen xinlai, but it is also something he does not want to accept.


    His friends are in Hunan Province, and his family is in Anhui Province. No matter from which angle or aspect, he has no contact with Hubei Province, that is to say, a netizen who used to know is a network writer in Sanzhen.


    Under such circumstances, even if Chen Xin accepts the solicitation, he should be in Hunan Province or his hometown Anhui Province.


    Moreover, considering the basic problems, Chen Xin could not give up everything he had in Hunan Province and come to Hubei Province.


    And to tell the truth, Chen Xin has pride in his heart. Cooperation with the state is the bottom line he can accept. Even if he is recruited, he thinks that at least it should be the departments with the national character, not the provincial character.


    So in order to avoid the trouble caused by being "despised", Chen Xin decided to show his "value" and make himself more important.


    At least let this Hubei provincial government official understand that one province is not enough to attract him.


    After thinking things over, Chen Xin stopped thinking, turned to the car battery, and then opened the system upgrade interface.


    In Chen Xin''s perspective, the familiar green light is still flashing, and the car battery has become an isotope thermoelectric battery.


    "So fast! But why did he change this way here? "


    "What is this for? Why can''t I understand this step! "


    "Is this strengthening the structure? Why do batteries use this structure? "However, in the eyes of the researchers on one side, what they saw was quite different. Even these specially selected researchers did not understand Chen Xin''s operation.


    Chen Xin didn''t feel surprised to see that they were puzzled, but he turned his eyes to the staff in charge of shooting to see if there were any different expressions on their faces.


    But obviously, the ability of the system is impeccable and powerful. These staff members are also confused and don''t understand. No one shows any special appearance.


    Seeing this, Chen Xin also had a bottom in his heart, so he went to a camera and asked the staff in charge of the shooting: "have I photographed my operation just now? Can you show me? I haven''t seen myself at work yet


    Of course, this staff member won''t refuse Chen Xin. After operating on the device, he played the picture just taken for Chen Xin in a small window.


    In the picture, Chen Xin sees that he has two hands on the table, and then he can''t understand the operation at all. It''s just like the old-fashioned cartoon shows that when making objects, there is a cloud of smoke between his hands, and then after all kinds of parts fly, things are done. After the same effect, the car battery becomes an isotope thermoelectric battery.


    Looking at the recorded picture, Chen Xin felt a little funny, but also shocked.


    Obviously, the concept of the so-called information state of the system is vague. Even these devices are covered, and there will be no difference between the pictures taken by the devices and the pictures seen by the naked eye.


    And what surprised Chen Xin most was that he only had a moment to click on the upgrade, but the picture captured by the camera lasted about ten minutes.


    Is this filling the storage medium with information in a flash?


    Chen Xin can''t understand this technology, but he can understand this effect. It''s just like those researchers who just see the moment of their own upgrading, but can make up a lot of brain processes. It''s obvious that they can only make up their brain in a moment when they get enough information. Otherwise, even if they have to make up a reasonable explanation, they don''t have enough information source material.


    This makes Chen Xin even more curious about what the film machine on one side has captured. After all, the shooting speed of this old machine is stuck. Digital products can write data instantly, but this old machine uses optical recording. It''s impossible to make the equipment run countless times faster in an instant and record all the information transmitted by light, right?


    In that case, the black technology of the system is too black.


    "Do you think this technique can be applied to the small nuclear reactor we are developing? I think his technology of processing battery shell can be used for core protection. This structure can effectively block the radiation from the reactor and save materials... "


    "Well, I think it''s appropriate, and the way he adjusted the contents of these batteries I didn''t know that adding these additives could turn the battery liquid into radioisotope! This technology is so powerful! The point is we''re standing so close that the Geiger counter doesn''t even ring! "


    "It''s a sight to rub the nuclear battery with bare hands! With these hands alone, I believe that this is acquired scholar syndrome. Normal people can''t practice such hands even if they study for a lifetime! It''s like living! "


    When Chen Xin was curious about the pictures taken by the film machine, those researchers had obviously completed the brain filling, but what they discussed surprised Chen Xin.


    What''s going on? Are they inspired by their own brain tonics?


    The concept of information state is vague, and it can''t have the effect of ancient god''s language, can it? Can you understand knowledge and technology after reading it? Before that, Qin LAN had seen the picture of upgrading her own items. Why didn''t she understand anything? Is it because Qin Lan''s knowledge level is not enough to understand these things, and these researchers have enough knowledge level to understand them?


    Chen Xin can''t imagine what these researchers saw in their eyes and what kind of information they got from the instant upgrade picture. However, it is obvious that what they have just gained is far beyond Chen Xin''s imagination.


    Because the eyes of these researchers looking at Chen Xin are no longer looking at a person, but at the feeling of a God.


    "I''ll put this battery in the car first, and I''ll get the rest later." Chen Xin said that he returned to the car with the newly baked isotope thermoelectric battery, opened the cover of the battery compartment and installed the battery on the car.


    Chen Xin asked for two car batteries last night. Originally, he planned to transform two ordinary batteries to make them work together. But just now, he adjusted his plan temporarily and made a move to rub the nuclear battery. He didn''t know how much impact this had, but it must be much bigger than what he had before.


    At least the Hubei provincial government official who just planned to recruit Chen Xin has become very dignified. If his mobile phone is not big enough now, he must have taken out his mobile phone to call the top officials of Hubei Province.

 Chapter 228

    The impact of rubbing a nuclear battery by hand, for anyone who knows how to do it, is as great as the impact of a nuclear bomb explosion.


    In the eyes of scientific researchers, it''s just like magic or pseudoscience. An ordinary car battery is just an isotope thermoelectric battery after being manipulated for more than ten minutes by someone. After an operation that is so hard to understand, it turns into an isotope thermoelectric battery!


    If they hadn''t seen this kind of thing with their own eyes, they would have seen a little bit of truth, and Chen Xin, the second finished product, left them to carry out various tests. Even if they killed these researchers, they would not believe that someone in the world could actually do such a terrible thing as rubbing a nuclear battery by hand.


    But after watching how Chen Xin made an isotope thermoelectric battery by hand, these researchers have no choice but to believe it.


    This undoubtedly makes these specially recruited researchers eager to let Chen Xin stay and work with them to figure out how he makes isotope thermoelectric batteries.


    But Chen Xin didn''t delay. After the researchers finished testing the finished product of the second isotope thermoelectric battery, Chen Xin took back the battery and drove away, leaving behind a group of researchers who looked as if they had been robbed of their wives. They watched Chen Xin''s armored RV go away.


    "That car actually uses nuclear power. I knew I should have come here last night. I can still study his car..."


    "Yes, the electric vehicle can pull such a heavy load, or track drive. I really want to have a look at its power system!"


    Several researchers are obviously full of curiosity and desire for knowledge about Chen Xin, but unfortunately, people have left, and they have no choice but to leave with the video data and the test data of isotope thermoelectric battery.


    However, the official in Hubei Province was full of regret. He knew that Hubei Province had missed a top talent this time.


    It doesn''t matter what people in Hubei province think. Chen Xin knows that with such a play, his existence will be known by higher-level figures.


    As for the future, although Chen Xin is not without plans and preparations, he has to go one step at a time. What kind of attitude and how the country will cooperate are very worth thinking about, but Chen Xin himself can''t grasp.


    After all, Chen Xin is only an Internet writer. He has only seen the story of a novel, and he has no idea what it will look like in reality.


    It is just like a multinational enterprise will not sign any strategic cooperation agreement with a small street workshop. It is almost impossible for a country to cooperate with an individual.


    But according to Chen Xin''s idea, after he has demonstrated his value and ability, the senior officials of Yanguo should still be willing to cooperate with him. After all, Chen Xin has demonstrated his talent in mechanical transformation as well as the manufacturing technology of isotope thermoelectric battery.


    He believes that the vision and insight of a country''s top leaders are enough to realize his own value.


    In Chen Xin''s opinion, cooperation itself is not a problem. The only thing he is not sure about is how the country will cooperate with itself.


    In Chen Xin''s view, the most appropriate way of cooperation is for the state to provide Chen Xin with prototypes and materials of various kinds of equipment, so that he can upgrade these equipment that may only be imagined in the laboratory, and then turn them into finished products, and then hand them over to the scientific research personnel for reverse research, so as to improve the scientific and technological strength of Yan country.


    After all, Chen Xin''s ability is limited. Even if he has a black hole on his neck instead of a head, his idea is limited.


    No matter how many ideas a person has, how can he compare with the talents of a country?


    As for what Chen Xin can gain by doing this, not to mention that the products upgraded by the system can help others improve their quality of life in an indirect sense and reap a wave of survival. Only by rebuilding the world in the ashes as much as possible and bringing life back to the past as soon as possible, can Chen Xin decide to do so.


    Thinking about these problems, Chen Xin drove along the road.


    In addition to seeing Zhang Chengguang off, he also came to the three towns to cross the Yangtze River.


    However, unlike Chen Xin''s idea of crossing the Yangtze River from the Yangtze River bridge or directly across the frozen river, there is a simpler and faster way to cross the Yangtze River from the three towns.


    That''s the river crossing tunnel.


    In the three towns, there are eleven Yangtze River bridges. Before the disaster, only one of them was still under construction, and the other ten bridges have been completed and opened to traffic.


    There are also two highway tunnels and four subway tunnels that have been opened to traffic.


    However, with the advent of the disaster, the last Yangtze River Bridge under construction has not been completed due to the bad weather after the disaster, while the other ten bridges have been damaged to varying degrees.


    Although after the disaster, the municipal government of three towns and the provincial government of Hubei Province have made great efforts to renovate and maintain the ten bridges, only seven of them have remained unobstructed, and the remaining three bridges have been suspended.And although it is still unobstructed, considering the maintenance of the bridge, there are some restrictions on the vehicles that can pass through the bridge. Tracked heavy vehicles such as Chen Xin''s armored RV are not allowed to pass the Yangtze River Bridge.


    So Chen Xin can only choose to pass through the river crossing tunnel, cross the Yangtze River underground from the Yangtze River waterway, and reach the other side of the river.


    Chen Xin has learned before that although the Yangtze River is frozen, there is still water flowing under the river. The thickness of the ice layer is about three to five meters. It is not a problem for pedestrians or ordinary household vehicles, but it is difficult for Chen Xin''s armored RV to guarantee that it will be able to pass.


    In case the car reaches the middle of the river, the ice will break and the car body will be stuck on the ice, not to mention falling into the Yangtze River. In this case, it is difficult to get rescue. Therefore, Chen Xin honestly chooses to take a ready-made road instead of driving directly from the ice.


    Moreover, passing through the Yangtze River through the river crossing tunnel is much easier than passing through the river.


    This also leads to the fact that although the traffic flow is far less than that before the disaster, there are still many vehicles passing through the river crossing tunnel, which is quite prosperous in the past.


    Chen Xin controls the speed and follows the traffic. Naturally, his tracked armored RV has attracted many people''s attention. Some people even flash at him when passing by.


    The lights in the tunnel are not as bright as before the disaster. The lights originally installed on the wall are basically out, leaving only a small part to maintain the minimum lighting in the tunnel.


    This is obviously to save electricity.


    After all, the larger the city is, the higher the power consumption will be. Even after a large city with a permanent population of over 10 million before the disaster has reduced a lot of power consumption, the daily power consumption is astronomical.


    In addition, the three towns are now actively carrying out post disaster reconstruction, and it is obvious that they need to save where they can.


    After all, although power plants still exist now, the state grid that used to connect the whole country was completely destroyed in the previous disaster. Most of the high-voltage transmission lines were damaged in the first wave of shock and fire.


    Each region can only rely on its own power plants to generate electricity, there will be a certain shortage of power supply, and the larger the city, the more obvious it will be.


    If the city where Chen Xin lives does not have the advantage of a large-scale power plant, he may not be able to wait for coal-fired power to be in short supply.


    So when visiting scientific research institutions before, Chen Xin also heard from scientific researchers that the relevant national scientific research institutions are now trying to study the technology of small nuclear reactor. Although there have been technical researches in this field before, the small nuclear reactor in the real sense has just been demonstrated before the disaster, and the technology has not been popularized on a large scale .


    This is one of the reasons why Chen Xin handed over the isotope thermoelectric battery to Zhang Chengguang. He hopes that the scientists in Yanguo can introduce more nuclear power technology from the battery provided by him, so as to improve the nuclear power technology of Yanguo itself and add strength to the energy problem of post disaster reconstruction.


    Now it seems that Chen Xin''s goal has certainly been achieved, which makes him feel better.


    Out of the tunnel, Chen Xin has been in the North Bank of the Yangtze River, along the road out of the city, Chen Xin once again faced with the choice of which road to take.


    Because of the actual use needs and the need to provide work for some survivors in the three towns, the snow on the roads in the city is cleared every day, so that the original roads can be exposed.


    But outside the city, there is still a snow cover, and the road can''t be seen at all.


    Let the car drive in the snow again, Chen Xin released the investigation UAV on the car, opened the map again, thinking about which road he would choose to take.


    There are many mountains to the north of the gaoguanjiang River in Hubei Province. If you want to go here to Anhui Province, there is only one highway from Sanzhen to Shanghai Stock Exchange and a national highway G318.


    Considering that it is difficult to travel in mountainous areas, Chen Xin actually has another choice, that is, to walk along another high speed along the Yangtze River, around a large circle, and walk in a relatively gentle area.


    It''s just that it will take longer on the road.


    So after thinking about the map, Chen Xin decided to take the national highway.


    It''s not before the disaster. It''s not a day or two to make a big detour. Moreover, Chen Xin, the national highway G318, vaguely remembers that he will pass by his hometown. He can''t go wrong along this road.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 229

    Out of the three towns, along the way it seems that you can not see the bustling city.


    In fact, along the G318 National Road, there are no big cities along the way.


    Because Chen Xin''s route is from mountainous areas, there are no more developed cities in this area, while the more developed cities in Hubei Province are either distributed in the west of Hubei province or concentrated along the Yangtze River.


    This does not coincide with the direction that Chen Xin wants to move forward, so it''s not unusual that he can''t see the city.


    The scenery along the way is still similar to that on the road before it. It''s dark everywhere, and the sight is covered with snow.


    He reached out and picked up a piece of dried fruit from the workbench and threw it into his mouth. Chen Xin was reluctant to chew it. He just sipped the taste of the dried fruit and missed it.


    Seriously, this seems to be Chen Xin''s first time to eat fruit after the disaster. Although it''s only dried fruit, it''s already a very rare thing.


    Just eating dried fruit, recalling the appearance of the three towns and the dark scene along the way, Chen Xin still felt the huge difference.


    In the big cities, the country has begun to rebuild after the disaster, and the general small and medium-sized cities have recovered from the disaster and began to actively resume production.


    Because the state, the army and the police still exist, everything is not as bad as expected.


    But in the countryside far away from the city, what should it be like?


    Chen Xin didn''t know and didn''t investigate, but judging from what he has seen and what he has learned, I''m afraid that the farther away he is from the city, the worse the situation will be?


    After all, the farther away from the city, the fewer places can be called underground bunkers before the disaster. Most of them may be just the cellars of farmers'' families.


    Even in the three months before the disaster, the state built shelters in villages and towns. Although most of the rural residents could escape the disaster, the time for the construction of those shelters was very urgent. It was difficult to say that enough shelters were built and that they could ensure that no one could provide the necessary living conditions.


    Lack of food and clothing, shortage of medical services and medicines, shortage of electricity and fresh water Chen Xin doesn''t even need to think about it to be able to count out a lot of possible problems.


    Especially for the lack of oxygen in his city before, the ventilation of small shelters may be better. In addition, there may be only one or two layers, and the depth may not be enough, so there will be no problems such as carbon dioxide deposition. However, it is difficult to have a good heat preservation effect for this kind of shelters which are not deep enough.


    Even if the temperature can be kept as high as possible, if there is not enough heating facilities inside, it will soon cool down and become like a huge ice cellar.


    Although it is possible for many people to survive in a shelter from the cold rather than directly facing the low temperature of minus 30 or 40 degrees, people in low temperature environment will need more high calorie food to maintain their body temperature, and people in low temperature environment are more likely to get sick.


    And what kind of consequences will these two lead to Chen Xin, who has played the ice age, clearly knows that once the number of hungry and sick people reaches a certain level, riots and discontent will breed.


    In the game, the rogue people will die of disease and starvation to a certain extent, and the discontent value will lead to riots and drive the managers away. But in reality, I''m afraid that when someone starts to die of disease, many problems and contradictions will break out, making things out of control.


    This also makes Chen Xin worry about his parents. They live in their hometown with their relatives. It''s just a county, and their parents and relatives don''t live in the city.


    Although all the people living together were relatives, they had lived together for several generations before the disaster, and even the ancestral hall for the Fengxian people was the same, which was not to say that there was any mess. Moreover, before the disaster, Chen Xin specially explained how they would hoard materials and build shelters, but his heart was still full of worry.


    It''s just that he''s worried that Chen Xin won''t be able to walk faster. His speed is much faster than he expected. After three towns, he has already walked half the way. It''s only five or six days since he started.


    This is much faster than Chen Xin''s estimate. According to his current speed, he is sure to arrive in Anhui Province in five days. Considering the return time, he can go back in almost a month.


    Even if there is something to deal with after receiving the parents, it will take a few days at most, and there won''t be too many variables.


    Thinking of this, Chen Xin felt relieved.


    Now he''s the only one in the car. Chen Xin has to find a way to adjust his mood so that he doesn''t get too impatient. Otherwise, although the car can speed up, it''s right, but it also means danger when it gets faster.


    This can be seen clearly from the snow covered road in front of Chen Xin''s eyes.


    In front of us, this section of road should have been built on the mountain. The road was dug out on the mountain, with mountain walls on one side and valleys on the other.But now with the snow covering the whole road, there is no trace of the road ahead. The snow has turned the whole hillside into a whole, making people unable to see where the original road is.


    "The snow is too thick!" Looking at the snow in front of him, Chen Xin frowned and was thinking about how to cross this section of road.


    The road is covered with snow, so it is impossible to take the original road, unless Chen Xin can clear the snow on the road.


    But Chen Xin has the time and energy to clean up the snow. He might as well find a way to change the road or upgrade his car so that it can drive on the slope like snow.


    Although according to the design, even on such a sloping slope, this crawler chassis has enough grip to ensure that the vehicle will not slide into the valley, it is a bit too risky to drive like that. If you are not careful, you will fall directly into the valley below.


    Chen Xin hesitated for a moment and let the two reconnaissance UAVs fly. He planned to scan the whole surrounding terrain to see if there was a gentle place for him to pass.


    Although there are mountains all around here, the mountains are not steep and precipitous. There are relatively flat places in the valley to pass through.


    However, compared with the original road, the journey from the valley is more winding.


    But now Chen Xin has only one choice, unless he wants to spend more time on the other side of the highway.


    Taking high-speed can only be a forced choice. Although the route of high-speed is straighter and the road undulation is less, there must be bridges and tunnels everywhere to build high-speed in such a place full of mountains.


    The tunnel is easy to say, but the bridge


    Recalling the collapsed bridge that he had seen all the way, Chen Xin directly let himself give up the plan.


    After all, even if Yanguo''s infrastructure strength is excellent, the infrastructure maniac will not be able to build a highway bridge that can withstand the impact of meteorites and will not collapse.


    Soon, the UAV will scan out the results back to the map on the console, in the form of color block displayed.


    Looking at the yellow and red areas on the hillside, Chen Xin can only focus on the relatively gentle green areas in the valley. While controlling the UAV to continue to scan forward, he also restarted the car and continued to move along the green block signs.


    It''s not dangerous to scan while walking, but Chen Xin''s speed can''t be raised. He can only creep forward slowly. The speed has dropped to 10 kmh, which is comparable to tortoise speed.


    "It''s really hard to go! Fortunately, there used to be a river in this valley. It''s a ditch. Otherwise, there might not even be a road. " Chen Xin shakes his head and compares the terrain scanned by the UAV with the map. Looking at the original river course in the valley marked on the map, he can''t help sighing.


    Just now, I thought I was not slow. As a result, I immediately encountered the situation that I had to slow down. Chen Xin could not laugh or cry.


    Fortunately, he has a good attitude. He doesn''t get impatient because of this situation. He has to pass quickly by force, but he can accept the current speed.


    In this kind of field driving speed itself is not fast, after all, it is not like driving on the road before the disaster, the road is flat and straight, there is no pothole and mud on the hardened Road, as long as you do not exceed the speed limit, you can step on the accelerator to the end and rush forward.


    When there is no road in the field, we must first plan a direction and route for ourselves, and then deal with the complex road conditions in various environments.


    Problems such as ponding and mud are the best solutions. Now in this eschatological environment, a series of obstacles, such as gravel, trees and rivers, have become snow covered roads. Relatively speaking, the road conditions have become single, but they are not better.


    If you have to make an analogy, driving in this snow covered area is actually the same as driving in the desert, except that the snow may be a little bit stronger than in the desert, and the wheels or tracks will not sink in so easily.


    The snow itself also has the potential danger of soft collapse, even the hole under the snow.


    This is why Chen Xin did not start the operating system to drive automatically, but held the steering wheel by himself.


    After all, people''s judgment ability and reaction ability are stronger than this kind of rigid operating system.


    However, this also made Chen Xin a little annoyed. When he was in Sanzhen before, he forgot to ask them for more resources and simply upgraded the car''s operating system to be intelligent.


    In that case, you can relax a lot, right? Chen Xin couldn''t help walking.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 230

    "It''s a tough road to go!" Looking at the planned route on the map, Chen Xin turned the steering wheel again and adjusted the car''s forward direction back to the projected route in front of his eyes. Then he scolded.


    All the roads on the mountain are covered with snow. The snow more than one meter thick not only makes it impossible to distinguish the roads, but also makes it impossible to walk on the mountain.


    But the valley at the foot of the mountain is not easy to walk. Although the terrain is gentle and there are places to pass through, the snow itself is soft and hard. Some places are frozen and hard, but it''s nothing to drive up. But some places are not frozen at all. If you don''t pay attention, the car body will tilt to one side.


    Even though Chen''s new car is equipped with radar and UAVs constantly scanning the surrounding environment, these devices are not strong enough to penetrate the snow and scan the snow.


    So Chen Xin can only judge the direction by feeling, and at the same time, with the help of the line planning of the operating system, he can move forward with difficulty.


    It''s not an easy thing to drive like this. Chen Xin must concentrate all his attention. If he doesn''t pay attention, it''s very likely that the car will overturn.


    If it wasn''t for Chen Xin''s big car and superior performance, maybe he would have overturned.


    Even with the intelligent assistance of the operating system, Chen Xin, after driving for two hours, had to find a relatively gentle and windy depression and stop the car for a rest.


    Putting down the hoe under the car body to make it stable, Chen Xin went back to the living cabin to pour himself a cup of hot water and planned to have a rest.


    However, during Chen Xin''s rest, the vehicle itself did not stop working, the radar was still scanning the surrounding environment in the largest range, the UAV was also flying forward to detect the terrain, and even the on-board operating system was analyzing the scanning results and planning the forward route.


    After all, Chen Xin''s journey depends on the existence of these things so that he won''t lose his way in the snow. Otherwise, there is no ready-made road. It''s dark all around, and even the prominent landmarks are covered by snow. It''s like driving all night in the snow in the middle of the night. There is no road, so it''s hard to get lost.


    Fortunately, novice Chen mastered the system and had a plan for these things. Only in this way could he successfully complete most of the journey without much delay on the road, let alone getting lost or going the wrong way.


    That is to say, when I just went out, I met the high-speed road and the bridge was broken, leading to a section of turning back.


    And all this is due to the equipment on the car.


    Chen Xin himself knows whether he can successfully return to his hometown depends on the equipment on the car. So although he has a rest, he still goes back to the cockpit after pouring water. He sits in the driver''s seat and looks at the operating system, analyzes the data sent back by radar and UAV, and plans his way forward.


    It seems that the road ahead is not easy to walk. Within the radar scanning range, there is a mountain which is not too high, but also several hundred meters high. Coupled with the problem of mountain trend, the valley at the foot of the mountain is very narrow.


    Originally, the road was tunnelled through the mountain, but the hundreds of meters of tunnel is really not worth mentioning for Yanguo''s powerful infrastructure and engineering capacity.


    But now the entrance of the tunnel is almost completely covered by snow. If a person wants to climb over it, it''s a good thing to say. After all, in the pictures taken by the UAV, the entrance of the tunnel is not completely covered by snow, and there is a gap less than half a meter wide leaking out. It''s OK to climb in and get people.


    But if you want to drive in, it''s impossible, unless Chen Xin is willing to spend most of the day digging up the snow.


    It''s not that we can''t dig. We just have time to dig the snow at both ends of the tunnel. Chen Xin can drive under the valley without wasting so much time. After all, the whole tunnel is only a few hundred meters long. Even if we need to walk around the valley, it''s just a matter of walking one or two kilometers more.


    Moreover, Chen Xin is more concerned about the snow on the mountain than this.


    Although the mountain is not steep, the side near the valley is not so smooth. In case of landslide and avalanche caused by snow more than one meter deep on the mountain, Chen Xin walking at the bottom of the valley will be directly buried by the snow.


    Chen Xin''s worries about avalanches are not groundless. Along the way, Chen Xin has encountered several avalanches. If the UAV hadn''t discovered them earlier, he might have been buried several times.


    Although Chen Xin''s car is so strong that he can escape even if it''s really buried by an avalanche, it''s better not to encounter this kind of thing.


    So Chen Xin now controls the UAV to take all-round pictures of the mountain, collect data as much as possible, and then analyze whether there will be an avalanche.


    However, according to the images, it seems that the mountain is unlikely to avalanche, which also reassures Chen Xin. He plans to have a rest and start again.


    Let the drone fly back to the car for charging. Chen Xin suddenly feels a little hungry and plans to go to the life cabin to get something to eat.


    However, just as Chen Xin stood up and went to the living cabin, there was a sudden shaking. The whole car was shaking. Chen Xin stretched out his hand to support the wall of the car and stabilized his body. He did not dare to stand up until the shaking passed.He was a little shaken. For a moment and a half, he didn''t know what happened.


    But the shaking didn''t last long, only about ten seconds. By the time Chen Xin finally got up, the shaking had subsided.


    "Earthquake? Or did it avalanche? " Chen Xin was a little suspicious. After thinking about it, he went back to the cab and scanned the surroundings again by radar. At the same time, he opened the car body self-test to confirm whether the shaking had caused any damage to the car body.


    When the radar is turned on, everything around seems to be normal, and no changes are found in the scanning. However, when a self-test brush is applied to the car body, no problems are found.


    This makes Chen Xin frown. It''s hard to judge what caused the shaking just now.


    If it''s an earthquake, it''s just a small earthquake with not too strong magnitude, at least it didn''t cause any damage to the car body.


    But if it''s an avalanche, it should be a big one if it can cause such a big shock.


    Only from the radar scanning, there is no change in the surrounding mountains. It doesn''t look like an avalanche.


    "So was it an earthquake?" Chen Xin is not sure what to pay attention to, and he always has a very bad feeling in his heart. So he puts down his water cup and plans to release the UAV for another scan.


    However, before the UAV took off, Chen Xin found that the water cup he put on the cup holder of the console began to ripple.


    Chen Xin quickly looked at the radar display, sure enough, the snow on both sides of the mountain wall has just started to collapse because of the earthquake.


    Avalanche! Chen Xin''s mind flashed this idea. He didn''t dare to delay at all. He quickly put away the hoe under the car body. Without waiting for the hoe to rise completely, Chen Xin had stepped on the gas pedal and let the car move. He wanted to escape from the valley which was about to be buried by avalanches on both sides.


    The snow surges down like a wave, driving more snow along the way and making the avalanche bigger and bigger. Chen Xin can even feel that the whole car vibrates more severely than just now. The water he put on the cup holder of the console has been sloshing out, but Chen Xin doesn''t care about it.


    The surging snow, like two waves, rushed down from the mountains on both sides, and even produced a great roar along the way.


    If it wasn''t for the lack of light, Chen Xin believed that at this moment, white snow and fog should have risen on the mountain walls on both sides.


    It was a spectacular sight. If he was not driving for his life, Chen Xin believed that he would be very happy to see the avalanche pouring down from the mountain in a safe place.


    But when they are under the avalanche, or two avalanches, no one is willing to use their lives to appreciate the spectacular.


    Chen Xin''s speed has been raised to the highest level. At this moment, he doesn''t worry about whether the ground is stable and whether he will fall into the snow pit. If he doesn''t run quickly, he will not fall into the snow pit, but will be completely buried by the snow.


    It seems that the maximum speed of only 80 km / h is not enough. Judging from the radar results, Chen Xin is afraid that if he can''t get out of the valley, he will be affected by the avalanche.


    At this time, Chen Xin is very glad that he has overloaded the car.


    Without hesitation, he photographed the red overload button on the console, and the car body suddenly heard a roar, as if a wild animal had been awakened and roared. The huge feeling of pushing back came from behind. Chen Xin could obviously feel that the speed had been greatly increased.


    Running 160 km / h with a crawler chassis is something Chen Xin does not dare to think about. Although he designed the overload mode, Chen Xin never thought that he would really use this escape function.


    It''s a very dangerous speed. A little carelessness may make the whole car fly out. But at this moment, Chen Xin can''t care so much. Even if he now has the whole car flying up and smashing on the snow due to the terrain from time to time, he doesn''t dare to stop at all.


    However, even though Chen Xin has driven the car to the fastest speed, the avalanche still mercilessly smashed down!


    For a moment, Chen Xin''s eyes were all gray. He couldn''t see anything clearly. Even the radar signal was a blur. He couldn''t scan anything at all.


    But Chen Xin did not give up, now it is just loose snow, he still has the chance to escape!


    At this time, no matter what the route planning, Chen Xin has given up adjusting the direction, just stepped on the accelerator and rushed forward.


    This is the only way he can escape from the avalanche.


    However, the snow still covered the car. At the moment when Chen Xin''s car body was suspended due to a raised ground, the snow from the mountains on both sides engulfed his car.

 Chapter 231

    "Hiss!" Chen Xin opened his eyes, but he felt a lot of pain in his head. As soon as he was ready to raise his hand to help his forehead, he felt a deep pain in his arm.


    "What the hell is going on!" The pain made Chen Xin swear, but he still tried to turn his eyes to his right hand, but his eyes were red with blood, and he felt that there was something in his eyes, which made him unable to see anything clearly.


    Chen Xin tried to lift his left hand, and found that his left hand did not feel the same pain as his right hand, so he touched his forehead with his left hand.


    Touch, is a greasy feeling, and was touched by the fingers of the place also came a burst of pain.


    It seems that he hit his head. Chen Xin has a judgment about his head. As for the red in front of him, it should be caused by the blood covering his eyes.


    Chen Xin is not sure how hurt he is, but he just feels dull pain in his head, and he is still sober. It is estimated that the injury is not serious.


    And from the bloodstain I felt, the amount of bleeding should not be very large, and the time is not long. After all, the blood has not dried, but it has stopped bleeding.


    But it should be dealt with in time. After all, it''s the head that''s hurt. If there''s something wrong, it''s not good.


    With this in mind, Chen Xin wiped his eyes with his left hand. After regaining his sight, he looked around to see what had happened.


    He is still sitting in the driver''s seat, the whole person lying on the driver''s seat, the car light is still, but the surrounding windows are all covered with snow, he seems to be buried under the snow.


    "So it''s still buried by the avalanche? What bad luck Looking at the snow outside the window, Chen Xin quickly found out what had happened before.


    After encountering an avalanche and overloading, he ran away quickly. As a result, he was still buried under the snow by the snow brought by the avalanche, and he fainted because of the collision. His head should have been broken just now.


    With this judgment, Chen Xin is relieved. He is afraid of more serious problems, but now it is not a big problem.


    The car body didn''t overturn. At least Chen Xin looked at the glass he had put on the console before, and there was even some water left in it. This proved that he didn''t overturn at least, and the car body was just a little crooked, which saved a lot of effort for his later extrication.


    However, the matter of getting out of trouble will be discussed later. For Chen Xin now, it is to deal with his own injury. The car is not overturned, the glass is not broken, and the heating inside the car body is still on. There is no big problem.


    "System, self test." Chen Xin starts the vehicle self-test of the operating system with difficulty. Listening to the inspection results reported by the inflexible voice of the operating system, Chen Xin finally looks at other parts of his body.


    His right hand seems to be fractured, his forearm bent into an abnormal arc, but there is no blood on his sleeve. It is estimated that the bone inside is broken, but fortunately there is no external skin damage, otherwise, during the period of his fainting, just bleeding can make him die.


    As for the rest of Chen Xin''s body, there seems to be no problem. He tried to move his feet, but he didn''t feel any discomfort, and his body is basically in good condition.


    Try to leave the driver''s seat, stand up and walk to the life cabin with his left hand supporting the car wall. Chen Xin has to deal with his injury.


    Fracture is a very troublesome thing. There is no detection equipment in the car. If you want to treat it, it may cause bone healing problems. In that case, this hand will be useless.


    Although Chen Xin is worried about this, he is not overly nervous. This degree of injury is not fatal. Even if his arm is really useless, it''s not a big problem for him to amputate and install a prosthetic body, or to make a new hand for himself after upgrading the medical equipment that can cure his head exploding.


    In a word, the hand problem can be put back. Anyway, Chen Xin can''t deal with the fracture himself now. He can only find a way to fix it first, and then consider how to treat it.


    However, the head injury should be dealt with in time. After all, the head injury and hand injury are totally different concepts, and the head injury is easier to deal with.


    When he came to the bathroom, Chen Xin stood in front of the mirror. In the mirror, his face was covered with blood, and his forehead looked like a big hole, but it was frightening. The blood had stopped by itself, and Chen Xin didn''t feel anything wrong except that he felt dull pain in his head.


    He took a little water with his left hand to wash the blood on his face carefully. Because only one hand can use it, Chen Xin spent a lot of time cleaning the blood on his face.


    Chen Xin did not clean the wound directly. On the one hand, he was afraid that the wound would bleed again. On the other hand, he was not suitable to clean the wound directly with clean water. It was better to clean it with hydrogen peroxide, so as to avoid wound infection.


    Although the risk of wound infection is very low in this low temperature environment, we should pay attention to it.


    After cleaning the bloodstain on his face, Chen Xin wants to take off his clothes, but his fractured right hand is obviously an obstacle. He can''t take off his clothes well, because if he wants to move his sleeve, he will inevitably encounter the fracture of his right hand.But it''s not a problem, it''s just a loss of a suit.


    Chen Xin finds out the medical box, takes out the emergency medical scissors from it, and directly cuts open his clothes.


    With the sharpness of the emergency medical scissors, the sleeves were easily cut. Chen Xin didn''t hesitate or give up. He cut all his clothes and took them off with his left hand.


    In fact, this is also a part of emergency first aid. If the injured person is found to have injuries, it is obviously too late to take them off one by one. It is the most simple and effective way to cut them all with scissors.


    Throwing his clothes aside, Chen Xin went back to the bathroom again, standing in front of the mirror to check whether he had any other wounds.


    Fortunately, he didn''t get any other injuries, even in the dark blue.


    That is to say, Chen Xin was injured only in his forehead and right hand.


    Taking out hydrogen peroxide from the medical box, because he had only one hand, Chen Xin had to open the bottle with one hand, and then found out the cup. After pouring out half a cup of hydrogen peroxide, he took a piece of gauze dipped in hydrogen peroxide to clean the wound on his forehead.


    Hydrogen peroxide reacts with the blood scab coagulated on the wound, constantly bubbling, and at the same time, it also makes Chen Xin feel a tingling pain.


    But he can only endure, must use hydrogen peroxide to clean up the wound, before the next step of treatment.


    After scrubbing with gauze, Chen Xin looked in the mirror, picked up the bottle of hydrogen peroxide, poured some into the wound and washed it.


    The piercing pain made him clench his teeth, and it took him a long time to ease.


    But the wound is clean, and now there is a trace of blood exudation.


    After a close look, Chen Xin was relieved to see that the wound was not too big. He continued to take out a first-aid kit from the medical kit and opened it. He tilted his head and sprinkled some hemostatic powder on the wound. Then he took a piece of clean gauze and dipped it in iodine to cover the wound.


    This is not the end. Chen Xin took a larger piece of gauze and folded it a few times before he covered it on the iodophor gauze on the wound. He pasted tape to fix it. This is the end of the treatment of the wound on his head.


    Now Chen Xin can only treat his own wound in this way. Although it is more correct to sew the wound and use anti-inflammatory drugs, Chen Xin can''t sew his head, so he can only make do with hemostatic powder.


    Fortunately, this bag of hemostatic powder also has some anti-inflammatory effect, which is enough for emergency treatment.


    After dealing with the head, the next step is the arm. In the


    medicine box, there was a bottle of emergency analgesic spray. Chen Xin sprayed some wounds on the wound. The feeling of cool Bing Bing cooled the pain on his arm quickly.


    But if the fracture wants to be healed, the most important thing is reduction and fixation. Topical drugs will not have much effect, that is, they can relieve pain and disperse stasis.


    Without the help of X-ray, it is impossible for Chen Xin to have fracture reduction. He is not an experienced orthopedic doctor. He can achieve correct reduction with his eyes closed and hands touched.


    And fracture reduction will be very painful. Even if Chen Xin can resist the pain, he can''t get his arm back to the right position.


    So what he can do now is to fix his arm. As for whether it will heal and dislocate, it can only be considered later.


    After taking out a roll of splint from the medical box and pulling it apart with the help of teeth, Chen Xincai put his right hand up, which inevitably brought him a burst of pain.


    Biting his teeth, he took out a roll of bandage and wrapped it around his right hand, fixed the splint with his right hand, and then bent his right hand back to hang it on his neck. Even if the fixation was temporarily completed, Chen Xin would not have any problems without moving his hand, making the injury worse.


    After dealing with the two wounds on his body, Chen Xin collapsed and sat on the sofa of the life cabin, and the whole person breathed a long breath.


    Looking back, Chen Xin felt a little cold. Then he remembered that his clothes had been cut to pieces. Now he had to take another clean one to put on.


    Although there is heating in the car and I feel a little cold naked, it is necessary to put on clothes.


    However, when Chen Xin found out the clean clothes and decided to put them on, he found a very serious problem, that is, his splinted right hand made him unable to put them into his sleeve, so he couldn''t dress well.


    In the face of this situation, Chen Xin had no choice but to find a thicker dress to put on his body first, and then he began to think about what he should do next.

 Chapter 232

    The injury has brought great inconvenience to Chen Xin. It is a great torture for him just to dress.


    The impact of the fracture of his right hand makes Chen Xin even move his right hand. When the muscle is pulled down, the broken bone will cause unbearable pain around the fracture.


    Dressing itself is an action that requires the cooperation of both hands. It can be said that every time Chen Xin moves, he has to endure the pain as if he were stabbed by a needle. However, the fracture itself makes him unable to finish dressing quickly, and his right hand can not cooperate.


    It took Chen Xin more than half an hour to put on his clothes, and the pain made him sweat.


    If Chen Xin didn''t have the foresight to bite a towel in his mouth, he would have bitten off his tongue in pain, which is really torture.


    After dressing up again and taking a rest for a while, Chen Xin began to think about getting out of trouble.


    In the previous system self-test, no damage was found. In addition to the damage caused by snow cover and overload driving, the avalanche did not cause any damage to the vehicle itself.


    Therefore, Chen Xin can spend time in the car to deal with the injury, dress, rest and think about how to get out of the difficulty. On the one hand, it is not to increase the air around his body so that he will not suffocate. On the other hand, it is also to expand the activity space of his limbs and increase the possibility of self-help.


    When there is enough space around the body to move, you can try to dig the snow around yourself and find a way to dig yourself out from the snow.


    For Chen Xin, with a car, it''s not difficult for him to do this.


    At least the power of a car is far greater than that of a person. As long as Chen Xin starts the car, he believes that it is not very difficult to drive the car out with the horsepower of the car and the snow on the top of his head.


    The key problem now is that Chen Xin doesn''t know how much snow there is on his head. If the snow is too heavy, Chen Xin still has to work hard to get out of the difficulty.


    And if you want to get out of trouble, just as recklessly let the engine turn, and then rely on the power of the vehicle itself to drive the snow, this is not the best way.


    This is not to say that it is impossible to get out of trouble, but it is the most laborious and the least efficient way to get out of trouble.


    Want to be able to more quickly out of trouble, or to take some more effective methods.


    Hanging his fractured left hand back to the cab, Chen Xin felt a headache when he looked at the thick snow outside the window, but no matter how many difficulties there are, they will always be overcome.


    Although there is a lot of snow, it''s not that he can only be reckless and can''t imagine. Chen Xin already has some ideas at this time, but he still needs to find something useful in the car to see if he can make it easier to get out of trouble.


    Chen Xin opened the console with his left hand and called out the list of various devices installed in the car, hoping to find out if there are any devices that can improve the intraocular pressure.


    "Radar? The previous antenna was damaged by the avalanche. It couldn''t be used before it was repaired Help hoe? Now that the whole car is fixed, it''s superfluous to put the hoe... " Chen Xin looks at all kinds of equipment he has installed in his car and judges the role these equipment can play one by one, but he always feels a little dissatisfied.


    These equipment on the car body can help Chen Xin in other environments, and the functions are also very complete. It can be said that Chen Xin has installed all the equipment that can be installed on a car.


    But these things have little effect on dealing with avalanches.


    Just when Chen Xin is thinking about whether he can only do things recklessly, and these devices are useless, a special piece of equipment gives Chen Xin an idea.


    Inflatable pontoon is a kind of airbag made of flexible material installed outside the car body. When the vehicle falls into the river in danger, or when it is going to pass through the ground which is easy to sink or accumulate water, such as mire or beach, it can inflate and expand the airbag to provide additional buoyancy for the car body.


    This is Chen Xin''s preparation for crossing the Yangtze River. He is worried that if he falls into the river or gets into an ice hole, he can rely on this to prevent the car from sinking.


    However, this device is not useful now. After all, it is cold and there is no place to use a float.


    But for the current situation, this set of things can be of some use.


    Opening the window, Chen Xin reached out to test the hardness of the snow, and found that it was still soft. He could make the snow fall down like powder with a flick of his hand, instead of freezing into pieces. Chen Xin had a better grasp of how to get out of trouble.


    The soft snow is more likely to be squeezed. In this way, you just need to expand the buoy, use the increased volume of the buoy to squeeze the snow around the car body, and then just fold up the buoy, you can expand the space around the car body.


    After getting more space, the car itself will have more space to move. In this way, the car itself will also have the power distance. Even if it is very short, it will save more effort than directly starting the car.


    With the idea, Chen Xin plans to start.After all, he is still injured. Although he has done emergency treatment, it''s better to find a professional doctor to have a look and deal with it again.


    In particular, Chen Xin''s right hand is still fractured. If we don''t find a doctor to reset the bone as soon as possible, then his hand is likely to be bent.


    Although there is no way to repair it, it can save some trouble. Chen Xin still hopes to cure himself as soon as possible and avoid all kinds of troubles when dealing with it later.


    And fracture is not a joke. In case the injury gets worse or necrotic, this hand will be amputated.


    Although the mantis knife is very handsome, Chen Xin also wants to try it on, but he never said that he would like to cut off his healthy hands to install the prosthetic body. He is not a fan of cyber prosthetic body. If he can use his original hands, it''s better to use the original ones.


    With Chen Xin''s operation on the console, there was a slight explosion around the car body, and then a burst of inflation.


    Chen Xin can clearly feel that the car body shakes. With the sound of inflation, the snow around the car window is obviously affected and seems to be pushed away.


    "It seems to have worked." Chen Xin looks happy and feels that he is hopeful of getting out of trouble.


    The next thing Chen Xin needs to do is to start the car, take advantage of the buoy to spread the snow around, let the car move, push forward more snow.


    However, after starting the car, you still need to take back the buoy. After all, if the car is just filled with air, the car body and snow will be squeezed after starting the car. Even if Chen Xin''s buoy is very strong, it will be very easy to crush the buoy.


    So Chen Xin waited for a short period of time, until the surrounding snow was a little more stable, then released the air in the float through the console.


    As Chen Xin released the air in the buoy, the snow around him collapsed obviously. At least Chen Xin could see that the snow outside the car window had dropped obviously.


    Seeing this, Chen Xin quickly started the car, stepped on the accelerator to a low level, and used the maximum torque to make the car move.


    Thanks to the loose snow around, the car started smoothly. Although he could feel great resistance, Chen Xin could still feel that although the car was very slow, it was moving forward unswervingly.


    However, what Chen Xin wants is to get out of trouble. It''s very difficult for the car to get out of the snow straight ahead. If you want to get out of trouble, you have to drive up.


    But it''s too hard for a car.


    After all, it''s easy for a car to go left, right, forward and backward, even if it wants to twist an S-shape, but it''s really difficult for a car to drive upward, because no car is designed to drive upward.


    Fortunately, it''s not difficult for Chen Xin. He controlled the car and drove forward a little bit. He felt that the body of the car could not move any more. Then he stopped the car and went back.


    Depending on this operation, a space of about five meters appeared in front of Chen Xin''s car.


    "Yes, next we just need to put something under the track to raise the front of the car." Chen Xin saw such a big gap in front of the car as he thought, and felt that he had a greater hope of getting out of trouble.


    However, the next work can''t be done in the car. If you want to pad things under the track, you can''t do it without getting off the car.

 Chapter 233

    With the help of two pieces of escape boards, Chen Xin successfully built a slope in front of the track, which raised the front of the car and finally allowed the whole car to drive up.


    This time, Chen Xin didn''t hesitate or hesitate any more. He stepped on the accelerator to the end and let the engine drive the track with maximum power, driving the whole car directly into the snow in front of him and rushed out with thick snow.


    After rushing out of the ground, Chen Xin released the drone again and looked back at where he was buried.


    What is left in place is a big hole about ten meters deep, which can even be used as the snowhouse of the Inuit with a little processing.


    However, Chen Xin also noticed that although the big hole he left was more than ten meters deep, the height from the bottom to the ground was not high, only about two or three meters high.


    Maybe this is the reason why Chen Xin was able to get out of the difficulty easily. After all, the weight of snow only a few meters deep is not an exaggeration, and there is no frozen solid, so it is not impossible to push it open.


    Of course, this is not an easy depth for ordinary people or ordinary cars. A few meters of snow is enough to suffocate a person below. Ordinary cars can''t start because their air intake is blocked by snow and they can''t breathe in air. Moreover, if the horse is not strong enough, they can''t open the snow after a few meters.


    Only Chen Xin''s car, which is driven by electricity, has enough horsepower and enough friction provided by the track, can push away the snow a few meters later and get out of trouble.


    Finally, Chen Xin took a long breath. He readjusted the UAV, observed the surrounding environment, and wanted to determine what the surrounding environment had become and how he would go next.


    Because the radar is damaged, Chen Xin is unable to scan the surrounding environment now, and can only rely on the infrared camera of the UAV to photograph the surrounding environment, which brings great trouble for Chen Xin to judge the situation of the surrounding environment.


    Fortunately, there are four UAVs in the car. After all of them are released, a reconnaissance network will soon be formed, and the surrounding terrain will be photographed, so that Chen Xin can judge his own situation.


    The snow on the surrounding mountains seems to have been brought down by the previous avalanche. On the contrary, there is no snow on the mountains, and even the roads buried by snow also show some traces.


    The valley is filled with a lot of snow, and the thickness of snow increases by several meters. It seems that the whole terrain has changed.


    In the face of this situation, after thinking for a while, Chen Xin decided to drive up the mountain and continue along the original road instead of going down the valley.


    One reason for this is that part of the road has been exposed after the avalanche. Although there is still a lot of snow on the road, it can barely drive on it.


    On the contrary, in the valley, because the snow brought by the avalanche has not frozen solid, the whole car will be trapped in the snow.


    And considering that Chen Xin still needs to find a doctor to deal with his injury, he needs to go to the next crowded place along the road.


    Although there are no big cities along the way, there are still several counties to visit.


    Through the voice control operating system, the car climbed up the mountain, returned to the road, switched to automatic driving, and continued to move along the road. Chen Xin was also looking for a place to go for help against the map.


    The village is obviously not good, not to mention whether there is a doctor in the village shelter, even if there is, it is estimated that the doctor in the small shelter will be very difficult to deal with the injury such as fracture.


    Chen Xin needs to set the bone and re fix his arm, so at least he needs to find a place where he can take X-rays.


    Because he switched to automatic driving, Chen Xin didn''t dare to drive too fast, so he had to drive slowly.


    Fortunately, the road is relatively flat after all, and some traces of the road are exposed after the snow avalanche. If you move forward against the map, as long as you don''t encounter the damage of the subgrade, it is more comfortable to run than to walk in the valley, and relatively speaking, the speed is faster.


    But even so, Chen Xin ran for a day, but still did not arrive at the nearest county.


    On the one hand, the speed of automatic driving is not fast and it doesn''t go too far. On the other hand, it is because Chen Xin took painkillers after he was injured, which makes him drowsy. In order to avoid the dangerous event that the car is still driving and people have fallen asleep, Chen Xin has to stop the car and find a place to have a good rest and sleep.


    After coming out of the three towns, there are only two prefecture level counties subordinate to Huanggang City on the way. The county close to Chenxin is very small in area from the map, which looks like a very ordinary small county.


    Chen Xin is not sure whether he can treat his injury here, but now this is the nearest place to Chen Xin for treatment, so he can only move forward to this county and take a chance.


    If there is no way to treat fractures in this county, Chen Xin will have to go back to the three towns for treatment or move forward to the next slightly prosperous county to see if he can get treatment.However, Chen Xin does not want to go back. After all, if he returns to Sanzhen for treatment, it will undoubtedly delay a lot of time. At this time, Chen Xin says that he may be able to reach his destination.


    As for Chen Xin, he would rather have a problem with his arm and cut it into a disguised form than delay his time on the road.


    To make up his mind, Chen Xin walked from the cab to the life cabin, dimmed the light, and then lay down on the bed to go to sleep.


    Because he hurt his arm, Chen Xin was worried that he would press it. He could only lie on his back to avoid touching the injured arm as much as possible.


    Looking at the splint and bandage wrapping his fractured arm, Chen Xin suddenly wants to try to upgrade the splint. Can he better protect his injured arm? Maybe when upgrading, he can add a bone setting function to straighten his arm?


    Chen Xin is a little eager to try, but he still gives up the idea because of his sleepiness.


    Bone setting can be very painful. Even those experienced orthopedic doctors in the hospital usually consider giving anesthesia injections when they reset the broken bone of the fracture, and then operate after local anesthesia. Otherwise, the patient will cry like a pig.


    After all, not everyone has the ability to scrape bone and cure poison. General Liu has the ability to count how many knives the doctor has cut.


    Chen Xin is just an ordinary person. He has no anesthetic in his hand, so he doesn''t want to try to set his bones without anesthesia. Especially now he wants to have a good sleep. In case he can''t sleep after the severe pain, he will be at a loss.


    With this idea, Chen Xin adjusted her sleeping posture to make her sleep as comfortable as possible. After that, she didn''t take off her clothes and just fell asleep in bed.

 Chapter 234

    Driving, Chen Xin slowly into the front of this quiet some excessive county.


    The town is too quiet for Chen Xin to feel the feeling and atmosphere that the county is still alive.


    Although the radar on the car is broken and Chen Xin can''t repair it because of his hand injury, the UAVs on the car are still good. Their infrared shooting function is enough to capture all the heat sources in this small county.


    When Chen Xin drove past Chibi before, even the UAV could capture the heat emitted from the vents of hot spring resort outside the city. Chen Xin didn''t think that the refuge in this small county could escape the search of UAV.


    But now the county is really a dead silence. Under the infrared vision of UAV, it is completely gray, without any color.


    "Damn, people in this county are all dead..." Chen Xin feels that he has a headache. If so, the problem will be serious.


    Of course, Chen Xin also hopes that this is his own thinking. After all, such a large county is a small one compared with other places, and even there are few high-rise buildings. According to the regulations of the state of Yan, even such a county should have at least eight people''s defense facilities to accommodate people for refuge. No matter how tragic it is after the disaster, it is not enough to say that all people are dead.


    After the disaster, although the road traffic was cut off and Chen Xin didn''t find a railway station in the city, he didn''t think that no one in the county would survive.


    Just looking at the dead city in front of him, Chen Xin still felt that something was wrong.


    The map of the county before the disaster was called out from the console. According to the marks on the map, Chen Xin marked the location of the county government, the hospital and the largest shopping mall. He planned to search these places with a UAV first.


    If there are still survivors in this county, these three places are the most likely.


    However, the UAV has made several turns in these three places, and even the battery is almost dead, there is still no discovery.


    Not only can not find any heat source, the ground is also covered by thick snow, there is no trace of human activity.


    "Isn''t this really a dead city? It''s impossible Looking at the pictures taken by the UAV in front of him, Chen Xin couldn''t figure out what was going on.


    Even if the county is short of materials and food, it''s only half a year after the end of the world. The traffic is cut off after the temperature drops. It''s not half a year yet. It''s impossible for all the people in the county to die in such a short time.


    But where did everyone go? Chen Xin really can''t figure it out.


    He called two reconnaissance drones back for charging, and planned to search again with two combat drones.


    However, before releasing the combat UAV, Chen Xin thought a little and controlled two combat UAVs to stop outside the door.


    Putting on his protective clothing and opening the car door, Chen Xin felt cold all over. However, he upgraded the two UAVs and added life detection modules to them before closing the door again.


    Rubbing his cold arm, Chen Xin went back to the cab. After drinking hot water, he continued to operate the UAV to search the whole county.


    This time, though, it seems a little different.


    There is still no one in the direction of the county government, but there are new discoveries in the direction of shopping malls.


    The upgraded combat UAV is equipped with a life detection module, which can search for signs of life within a radius of 500 meters. After the upgrade, Chen Xinfa still has several signs of life in the underground garage of the shopping mall.


    And one of them seems to be leaving the underground garage and wanting to go somewhere else.


    This makes Chen Xin interested. After flying a UAV into a shopping mall, he finds a clean place to land down and monitor several signs of life left in the underground garage. Chen Xin controls the sign of life that another UAV left behind, hoping to see what happened.


    The people who left did not choose to go out of the city or find a place to hide, but walked in the direction of the hospital.


    "Is someone sick and looking for medicine?" Looking at the figure captured by the infrared camera of the UAV, Chen Xin became interested in the purpose of the man, but he still wondered: "but how can there be so many living people in such a big county?"


    Although the county in front of us is only a small one, even so, it seems that there should be at least more than 100000 people. Even if the disaster hit, most of the people died, but it is impossible for only a few people to survive in such a large county.


    Maybe the answer lies in these people, but for now, it''s better to find out what this person is doing in the hospital. If there are doctors among the survivors, Chen Xin feels that he can''t help them, as long as they have the ability to treat their own fractures.


    Under the surveillance of the UAV, the figure laboriously entered the abandoned hospital.


    The figure seems to be very familiar with the hospital. After entering the hospital, he did not search everywhere, but went straight to his goal and searched for what he wanted to find."It looks like a hospital person, maybe a doctor." Chen Xin saw the identity of the other party from the action of the figure. At least he should have worked in the hospital, otherwise he would not be so familiar with the hospital.


    Through the pictures taken by the UAV, Chen Xin noticed the other party''s way forward. If he is not familiar with the hospital, he may search room by room, but he obviously knows the route and what he is looking for. He did not hesitate about the way forward.


    "The hospital was burned, and now it''s almost frozen. What is he looking for? Does anyone need medicine when they are ill? " Chen Xin stares at the display screen on the console, touches his chin and has an idea.


    He controlled the drone to fly in from the broken window of the hospital, and then walked around behind the figure.


    The figure obviously heard the sound of the propeller of the UAV, looked back at the UAV like a frightened rabbit, and was obviously startled by the sudden appearance of the UAV.


    Chen Xin turns on the searchlight on the UAV, and the snow-white light illuminates the figure. Before the other party, there is only a small flashlight in his hand. The sudden strong light makes the person quickly raise his hand to cover his eyes, and he wants to turn around and run away.


    However, Chen Xin, who managed to find a living person, obviously won''t let the other party run like this, so he controlled the UAV and blocked the other party''s way directly. He picked up the car''s walkie talkie and yelled through the buzzer on the UAV: "don''t run, there are guns on the UAV."


    Hearing Chen Xin''s voice, the figure just froze in the same place. Looking at Chen Xin''s figure in disbelief, I don''t know what to do.

 Chapter 235

    The figure who was controlled by the UAV froze in the same place, looking at the UAV with great fear, and did not dare to run away.


    But it still can''t hide its own fear. Through the camera of the UAV, Chen Xin can clearly see the man shaking constantly.


    Chen Xin knew that he had scared the man, but he had no choice but to say to him through the UAV: "follow the UAV and walk out of the hospital slowly. If you dare to run, I''ll shoot. Your companions in the shopping mall are also under my surveillance, so don''t think you can escape."


    Chen Xin mentioned his companions in the shopping mall, which undoubtedly made this man more afraid and scared. He was more nervous, for fear that some of his actions might lead to Chen Xin''s misunderstanding and hurt his companions in the shopping mall.


    "I''ll do what you say!" It seems that the figure said something, but Chen Xin didn''t hear it. There was no microphone installed on the UAV. However, seeing the figure''s hands raised, Chen Xin roughly understood what he meant, so he controlled the UAV to fly out.


    Instead of trying to escape, the figure obediently followed the UAV and came out of the hospital. Then he stepped on the snow with deep and shallow feet and followed the UAV to Chen Xin''s car.


    When tracking with the UAV, Chen Xin has already driven the car nearby, even earlier than the man who is being detained by the UAV.


    Seeing that someone has come, Chen Xin is ready to open the door and let the other party get on the bus, but before that, he must make some preparations, so as not to make the other party think that he is injured and have some unnecessary thoughts.


    He took out his smart pistol and put it on the table in front of the sofa. Chen Xin sat down in the middle of the table and put the gun in the most convenient position. In this way, even if the other party had any plans after coming up, he could not rush to Chen Xin at the first time. Chen Xin could easily pick up the gun and shoot.


    Ready, Chen Xin Let the operating system open the door and said to the figure standing at the door, "come up."


    This person seems to have been in a state of panic, whether it is the UAV or the armored car in front of him, some beyond his imagination.


    After waiting for someone to get on the bus, Chen Xin said to close the door. However, the closing of the door seems to make the person in front of him more and more afraid.


    Chen Xin has no intention of alleviating this fear. Sometimes fear helps to communicate.


    So he said straight to the point, "answer my question, if I''m satisfied, I''ll let you go, and I''ll let your partner go."


    "Really?" This man looked at Chen Xin, his eyes were burning. Obviously, under great fear, he would not let go even a little hope.


    Just hearing this man speak, Chen Xin looks a little strange and asks him, "are you a woman?"


    It''s no wonder that Chen Xin has such doubts. Although this person is thin and small, because of the cold, she is covered with a thick layer of protection and looks very bloated. She can hardly see her gender. Chen Xin can see that it is the result of wearing several layers of clothes.


    Her face was wrapped in a scarf, and she was wearing something similar to protective glasses, but it was very dirty, and it seemed to be seriously damaged. It could only be said that it was barely windproof and had no practical effect.


    In addition, she has been wearing a hat. It''s not surprising that Chen Xin can''t see whether she is a man or a woman.


    Gender exposure didn''t deepen the fear of the man in front of her. She just stared at Chen Xin like a drowning man seizing the last straw and confirmed to Chen Xin: "will you really let me go? Will you let my companion go? "


    "As long as you answer my question truthfully." Chen Xin gave a positive answer.


    The woman in front of her obviously got hope from Chen Xin''s answer. She managed to calm herself down and still held her hands high in French military salute. She said to Chen Xin, "ask me."


    Chen Xin nodded slightly and asked her, "why did you come to the hospital?"


    "Someone''s sick. I have to come for medicine." The woman didn''t hide her purpose. Her companion in the shopping mall was also found. She didn''t have any need to hide.


    "Why are you so familiar with hospitals? What medicine are you looking for?" Chen Xin asked a question that had nothing to do with what he wanted to know.


    "I used to be a pharmacist in the hospital. One of my companions had a high fever. We were short of drugs. I came here to look for antipyretic and anti-inflammatory drugs." The woman continues to explain, but her career disappoints Chen Xin. He thinks she is a doctor and can help him.


    Chen Xin''s disappointment was obviously noticed by the woman. She noticed Chen Xin''s arm and head injuries hanging in front of her body, so she quickly said, "if you need someone to treat you, I have learned first aid. If you are willing to believe me, I can show you some common injuries that I can deal with!"


    The woman is not kind-hearted, but hopes to highlight her role by treating Chen Xin, so as not to be killed by him as a useless person.


    After all, although Chen Xin has not pointed a gun at her so far, the gun on the table still gives her a great sense of deterrence."I don''t believe you yet." Chen Xin waved his hand and did not ask the woman to treat him. Instead, he continued to ask, "Why are there only a few living people like you in the county? Where are the others? Why are you still here? "


    Chen Xin''s question made the woman''s eyes look strange. It seemed that she was wondering why Chen Xin didn''t know about these things, but she answered truthfully: "people in the county town were moved to Huanggang City before the temperature dropped. We were from the surrounding villages. When we moved, we received the news relatively late. When we arrived from the village, we got to the county town People have already left, we can''t catch up, so we are stranded in the county


    This answer is a good answer to Chen Xin''s doubts. After all, it''s strange that a living person can''t see such a big county.


    And to answer this question, Chen Xin is not surprised why the woman and her companion stay in the underground garage of the mall.


    When the woman answered these questions, Chen Xin couldn''t figure out what else to ask, but after hesitating for a while, he asked the woman, "can any of you treat fractures?"


    "Fracture? Is your hand broken? " Hearing Chen Xin''s question, the woman naturally looks at Chen Xin''s right hand hanging on her chest.


    "It''s none of your business. You just have to answer whether I can or not." Chen Xin put his left hand on the pistol on the table.


    Seeing Chen Xin''s action, the woman replied busily, "yes! I can treat fractures! "


    In the face of the woman''s answer, Chen Xin has doubts: "you? How does a pharmacist know how to treat fracture? "


    "I really understand! I''ve learned first aid, and I''ve helped people deal with fractures. As long as it''s not too serious, I can handle it! " The woman seems eager to prove herself. She takes two steps forward and seems to want to come to Chen Xin to check his injury.


    However, seeing the woman approaching him, Chen Xin''s left hand immediately picked up the gun and pointed at the woman.


    Being pointed at by Chen Xin with a gun, the woman hurriedly retreated, her eyes full of fear: "I have no other meaning, just want to see your injury! Really, I didn''t lie to you! "


    "My hand fracture, although not serious, but the bone has been dislocated, I need a professional doctor to help me with bone reduction, you know what I mean?" Chen Xin did not put down his gun, but looked at the woman and said it seriously.


    "Although I''m not a professional orthopedic doctor, I really can set the bone. If your arm is only slightly fractured, it''s not difficult to reset it!" Although the woman is not a professional orthopedic doctor, she has worked in the hospital and learned first aid, so she can still get a rough idea of the injury.


    And although Chen Xin is hanging his right hand, the woman can see that the curvature of his right hand is not big. For some people who know how to reset, they can even reset the fracture themselves.


    This degree of fracture is still within the range of treatment for a woman.


    Listening to the woman''s words, Chen Xin hesitated for a moment, but finally put down his gun, pointed to the medicine box beside him and said: "there are anti-inflammatory drugs and anti fever drugs you need in the box. I can give them to you, but the premise is..."


    "I know. Fix your fracture." The woman forced herself to calm down. Instead of looking at Chen Xin''s gun on the table, she nervously walked up to him and said, "can you show me your hand? I need to examine your injury


    Chen Xin nodded and motioned to the woman to look at his arm.


    With Chen Xin''s permission, the woman nervously came to him and carefully stretched out her hand to untie the bandage hanging her right hand. Then she dragged his right hand and gently untied the bandage and splint.


    Seeing Chen Xinna''s swollen and unnaturally bent right arm, the woman pressed it carefully, which caused Chen Xin to frown and hum. She quickly explained, "I want to confirm the fracture of your bone. At present, there is no X-ray machine, so I can only touch it like this."


    what Chen Xin said nothing, just nodded, said, "there is a pain killer spray in the medicine box."


    "I''m going to get it now!" The woman hurried away from the medicine box and put out the spray of pain relief and sprayed on Chen Xin''s arm. After


    sprayed the painkiller, Chen Xin felt that the pain in her right arm had been relieved for a while.


    Seeing this, the woman gently touched Chen Xin''s right arm with her hand and felt the fracture of the bone.


    "The good news is that your bone fracture is not serious. I can reset it." After the woman''s examination, she said to Chen Xin, "but the bad news is that I need help, or I won''t be strong enough alone."


    Chen Xin''s eyes narrowed for a while. After thinking for a while, he said, "don''t play tricks."


    With that, the operating system drove the car to the mall, and sent the combat UAV beside it.

 Chapter 236

    "What''s your name?" Chen Xinxin let the woman deal with the wound on her forehead again. Because it hurt a little, she chatted with her to distract her attention.


    "Zeng Liu, the willow of willow, my father has no culture. When he named me, he saw the willow in the ditch at the gate, so he named it." The woman, Zeng Liu, carefully peeled off an old gauze from Chen Xin''s forehead with tweezers and washed the scabby wound on his forehead with a cotton ball dipped in alcohol.


    After cleaning up the wound, Zeng LIUCai said to Chen Xin, "although you used hemostatic powder to treat the wound is the right emergency method, it also has a little impact on the wound, which may leave a scar."


    "It''s a small problem. It''s not in the way." Chen Xin doesn''t mind having a scar on his head. It''s no big deal for a man.


    Under the control of the operating system, the car drove to the shopping mall. After Zeng Liu re drugged and bandaged Chen Xin''s forehead, he packed the things on the table, put them back in the medicine box, and threw the dirty gauze into the garbage can on the car.


    Feeling Zeng Liu''s wound after dressing herself again, Chen Xin took a look at her and said, "your dressing level is good. Thank you. If you can cure my hand, I can help you get out of the county


    Hearing Chen Xin''s words, Zeng Liu was obviously moved, but he didn''t say anything. He just nodded to show that he knew about it.


    There are no living people in this county. Zeng Liu and his gang could see several living people in the city before, but now there are fewer and fewer living people, and they haven''t seen anyone else for a long time.


    Now the materials are more and more scarce. Although the materials that can be collected in this county are not lacking, the materials that they can collect are almost consumed.


    In the present situation, if they can''t leave the county, go to other places of refuge, and wait for their end, it will undoubtedly be death. The only difference is to choose between freezing death, starvation death and death.


    So hearing Chen Xin say that he can take her away, Zeng Liu is really excited.


    Just before Chen Xin''s attitude and the gun in his hand scared Zeng Liu, she can''t believe Chen Xin at this time, also can''t show too excited.


    They didn''t say much, and the car soon drove to the mall.


    After driving into the underground parking lot, Chen Xin found a windy place to stop the car and said to Zeng Liu, "go to find your partner. You can take the medicine first. After you finish your work, you can bring someone to treat me."


    "I know. I''ll be back when I get the medicine." Zeng Liu nodded, indicating that he would not play tricks.


    Just now, Chen Xin has shown her the surveillance ability of UAV. At the same time, he has made her understand that the novice Chen is carrying a real gun, which makes Zeng Liu even more afraid and dare not have any other ideas.


    Now it''s the end of the world. In the struggle to survive for more than half a year, Zeng Liu has witnessed more than one killing.


    In Zeng Liu''s opinion, Chen Xin is not a good man or a good woman. She dares not gamble on Chen Xin and dare not shoot.


    After getting out of the car, Zeng Liu put on the scarf he had taken off from the car for the convenience of cleaning Chen Xin''s wounds. He could not help but take a breath of air conditioning to cool his overheated head, which was roasted by the heating because he stayed in Chen''s new car. At the same time, he calmed down his mood.


    She looked back at Chen Xin''s car and bit her lip. She knew clearly that Chen Xin''s two drones were monitoring his companion in case of any tricks.


    But Zeng Liu knew that he would not play tricks, but his companions were


    Zeng Liu shakes his head and shakes these ideas out of his mind. He pinches the medicine he gets. No matter what, once he gets the medicine, his friends will be saved.


    Through the quiet and dark underground garage, Zeng Liu went down to the next floor of the underground garage by the flashlight on her hand. It was also transformed into a refuge, but now only Zeng Liu and her companions live here.


    Although the shelter''s facilities are relatively complete, they can''t start the heating boiler or use the generator for lack of materials. They can only get some furniture from the shopping mall above and use it as firewood for heating.


    That''s why Chen Xin didn''t scan the heat source. After all, there were only one or two bonfires, and the heat had almost dissipated before it was transferred to the surface through the ventilation pipe.


    "Zeng Liu, are you back? Have you found the medicine? " Seeing Zeng Liu coming back, one of her companions who had been waiting for her rushed to meet her, with a happy look on her face.


    Zeng Liu nodded to him and asked, "how is sister Ning? Is her condition stable? "


    As she asked, Zeng Liu also looked at several other companions sitting around a dark campfire. What she was most worried about was these people. They were not Zeng Liu''s first companions, but appeared here after the massive evacuation of the county.


    Zeng Liu didn''t know where these people came from, but Zeng Liu had seen them kill people.Since then, Zeng Liu and her companions have kept away from this group of people. With two policemen and a pistol among them, they can still frighten this group of people and maintain the safety of both sides.


    But now one of the policemen in Zeng Liu''s group has fallen ill. While the deterrent power is weakened, it also makes the other party ready to move.


    On the one hand, Zeng Liu took the risk of looking for medicine because the sick person was her friend, and on the other hand, it was to maintain her own deterrent power.


    "Fortunately, I have been using a towel to help her with hot compress. Now the situation is stable. Have you got the medicine?" The companion is another police officer, but he and the sick sister Ning are just ordinary police officers, or even the kind of assistant police officers who have no establishment.


    If it wasn''t for the uniform and a little deterrent, and they came out with a gun from the police station, they couldn''t frighten those vagrants who were not good people at first sight.


    Originally, he did not agree with Zeng Liu to go out to look for medicine, but now in this case, once one of the two policemen with deterrent power on their side falls down, the fragile balance between their small group and each other will be broken.


    "When we get the medicine, let''s go to sister Ning''s room and let her take it first." With that, Zeng liula and his companions planned to go back to their room.


    However, just as they were about to walk into the room, several people in the group by the campfire stood up and blocked Zeng Liu''s way: "you actually got the medicine. It''s really unexpected, but I don''t want to waste it. Anyway, she is dying of illness. It''s better to leave it to us, and it can be used more."

 Chapter 237

    "What do you want to do?" Zeng Liu looked at several people blocking in front of him, and his face became more and more nervous.


    "What for?" The head of a tramp showed a bad smile: "ha ha, we don''t want to do anything, just hope you don''t waste precious medicine on people who can''t be saved at all."


    "What are you talking about! Sister Ning just has a fever. She will get better after taking the medicine! " Zeng Liu felt a burst of anger.


    Of course, she can hear that the purpose of these people is to prevent her from saving sister Ning, so that the strength of Zeng Liu and his group will become weak. At that time, these vagrants will be able to eat them, snatch the materials they have, and even kill or enslave them.


    Zeng Liu''s companions also felt angry and directly pulled out the gun, which was their biggest deterrent. They had a strong deterrent to these vagrants before.


    But this time it doesn''t seem to work.


    "Hey, hey, you took out your gun, then you shot it!" It seems that the leading vagrant does not pay attention to Zeng Liu''s gun at all.


    However, if Zeng Liu and her companions can calm down, they can see that there are sweat stains on the forehead of the head tramp.


    In fact, the other party was also very nervous, but deliberately provoked Zeng Liu and her companion''s anger with provocative words and irritating attitude, making them lose their calm and judgment. The gamble was that Zeng Liu''s companion was just an assistant police officer and did not dare to shoot at all.


    Of course, the leading vagrant also knows that if a person is angry, he will do something irrational, so although he deliberately uses words to motivate Zeng Liu and her companions, he does not press too hard.


    Seeing his companion pull out the gun, Zeng Liu quickly pressed his arm, pressed down the muzzle of the gun, and said to him, "Old Tang! chill! Don''t be impulsive


    After comforting her companion, Zeng Liu looks at the head tramp angrily. Seeing the pleasure on the other side''s face, Zeng Liu bites her teeth. She knows what the other side wants to do, but she doesn''t have any time to waste.


    Chen Xin outside gave her a strong sense of oppression before. She didn''t dare to gamble on how much patience Chen Xin had to wait for her.


    In case Chen Xin thinks Zeng Liu is playing tricks on him, or gets impatient and lets the drones come in to kill him, he can''t even stop the two drones with these rotten fish and shrimps.


    "Listen! I don''t have time to argue with you! Get out of the way, I can''t afford to delay it Zeng Liu tried to push the vagrants away, but they pushed them back. One of them was unstable and nearly fell to the ground.


    On one side, Tang quickly helped Zeng Liu and glared at the vagrants.


    "Hey, I can''t afford to delay. I''ll just delay. When that smelly woman dies, you don''t have to waste precious medicine to save her. Ha ha ha!" The head of the vagrant laughed, and the other vagrants behind him also followed a strange laugh, which made Zeng Liu angry and anxious.


    She said the delay can''t afford is not refers to the sick Ning elder sister, but outside still waiting for her to give him the treatment of fracture Chen Xin.


    However, when Zeng Liu pulls old Tang, who wants to have a conflict with the group of vagrants, and plans to get up and ignore the group of vagrants, she suddenly hears the sound of the propeller of the UAV.


    "What''s that noise?" The tramps apparently heard the sound, but they didn''t recognize that it was a drone.


    Zeng Liu''s face changed at this time. He quickly got up, took out the medicine he had brought back and gave it to Lao Tang. He said to him, "Lao Tang, take the medicine quickly and I''ll delay for a while."


    Then he wanted to go outside and ask Chen Xin to let the UAV wait a little longer.


    However, when Zeng Liu turned to the door, all four drones had come in, and the muzzle of two combat drones had been aimed at the group.


    "Miss Zeng Liu, my time is precious. Please don''t waste it." Chen Xin''s voice comes out of the UAV, which can keep the indifferent business. It is particularly nervous to match the fan sound of the UAV.


    Zeng Liu quickly explained to the UAV, "I''m not wasting time, I''m just delayed. Please wait a little longer, and I''ll finish the work here soon!"


    With that, Zeng Liu turned to Lao Tang and said, "Lao Tang, you go to feed elder sister Ning quickly. Then you guard elder sister Ning and call little leaf. I need his help when I have something to do!"


    The appearance of the four UAVs obviously shocked the vagrants who intended to be in a dilemma with Zeng Liu, especially the barrel of the two combat UAVs.


    After all, these four drones don''t look like what should be here.


    Lao Tang was obviously confused by the situation, but he was not surprised. He took the medicine Zeng Liu gave him and went to their room. Before leaving, he did not forget to give the gun to Zeng Liu''s hand to keep her self-defense, but also to continue to deter these vagrants.


    The head of the vagrant obviously saw this scene, he couldn''t help but turn his eyes and thought of an idea.


    "Zeng Liu, what''s going on? Where do these drones come from? " The head of the tramp raised his hands and went to Zeng Liu. While staring at the UAV, he asked Zeng Liu in a low voice."When I went to the hospital, I met a man with a fracture. He asked me to help treat the injury. He was in control of these drones. Don''t mess around. These Drones will really shoot." Although Zeng Liu had a gun in her hand, she didn''t dare to shoot at all. She just raised her hands with a gun in one hand and pointed the muzzle toward the ceiling to avoid causing Chen Xin''s misunderstanding.


    However, some people would like to try what Zeng Liu did not dare to do.


    The Ranger standing beside Zeng Liu''s eyes fluttered to Zeng Liu''s gun. In his opinion, as long as he grabbed the gun and shot down the UAV before it was fired, there was no problem.


    Zeng Liu said that these drones are controlled by people, but the people who control the drones have broken their arms. A wounded person should be very easy to deal with. As long as they shoot down these drones, can they still deal with a broken disabled person?


    He thought so and did so. Before Zeng Liu did not react, he snatched the gun in her hand and pointed at the UAV to shoot.


    But the gun didn''t ring.


    Chen Xin, who saw this scene from the pictures taken by the UAV, was almost laughed, but it didn''t affect his judgment and decision. He directly pressed the shooting button.


    The machine gun under the combat UAV instantly locked the group of vagrants. With only a few slight noises, they all fell to the ground.

 Chapter 238

    When Lao Tang finished feeding the sick elder sister Ning, he rushed out of their room with the little leaves that had taken care of her. He wanted to help Zeng Liu, but what he saw was the tramps who had fallen to the ground and were constantly wailing, and Zeng Liu, who was standing by with his hands raised and his face dull.


    "Zeng Liu, what''s the matter?" Looking at the tramps who fell to the ground and were shot in the leg, Lao Tang was also frightened.


    For a moment, don''t know what to do, old Tang can only learn from Zeng Liu''s appearance, raised his hands, put on the French military ceremony, stood beside her, to avoid being attacked by UAVs.


    But Xiao Ye, who came out with Lao Tang, looked at the four drones curiously. He didn''t think these things were dangerous. Instead, he was full of curiosity.


    "They wanted to shoot these drones, and you saw them all." Zeng Liu also felt very helpless. She had tried her best to avoid getting into trouble, but these vagrants still made things develop towards the situation she least wanted.


    Chen Xin also felt helpless when he looked through the camera of the drone at the three men who saluted him.


    If he can, he certainly does not want to create such a situation that he is a villain, but it is the most important thing to cure his arm now, and it is not important what these survivors think of him.


    The big deal is that after they have treated themselves, they fulfill their promise to Zeng Liu, take them out of this deserted County, and find a shelter to put them down.


    However, it''s still important to urge these people so that they don''t continue to stand and salute the French army. Although it''s very interesting, it''s still more important to treat their own fractures.


    "Miss Zeng Liu, can you treat me now?" Chen Xin once again called Zeng Liu through the drone''s buzzer.


    Hearing Chen Xin''s words, Zeng Liu''s face looked even more flustered. However, she still kept her emotions and said to Xiao Ye, who came out with Lao Tang: "Xiao Ye, you come with me, Lao Tang, you take care of sister Ning. If this can be done, we can leave here."


    "What about these guys?" Looking at these tramps on the ground, Lao Tang didn''t know whether to save them or not.


    "They..." Zeng Liu didn''t know what to do, but after thinking about it, he said, "let them stop bleeding by themselves, but they were shot in the leg and tied up the wound with a cloth strip. They can''t die."


    At this time, Zeng Liu also knew that it was not a time to spread his sympathy, and he didn''t have much sympathy for these vagrants.


    Lao Tang nodded to show his understanding. After looking at the four drones in fear, he carefully picked up the gun on the ground, said a word of caution to Zeng Liu and Xiao Ye, and then returned to their room.


    And Zeng Liu also looked at the little leaf, bit his teeth, and took him out, leaving only a tramp groaning with his legs covered.


    Zeng Liu with a small leaf came outside, Chen Xin''s car is still in place.


    "Little leaf, don''t look or talk after going up later. That person is very dangerous." Zeng Liu tells Xiao Ye to come to the door with him, waiting for Chen Xin to open the door.


    The door opened, and Xiao Ye got into the car after Zeng Liu with curiosity.


    In the car, Chen Xin is still sitting on the sofa with his gun in front of him, and his face is very flat.


    In Xiaoye''s eyes, this is just an ordinary looking person, not as dangerous and terrible as Liu once said.


    But according to Zeng Liu, he didn''t look at or move anything.


    But Chen Xin took a look at Xiao Ye and asked Zeng Liu, "is this your companion? It looks like a kid. "


    "Xiaoyezi is only 14 years old. She should have gone to high school." Zeng Liu explained to Chen Xin, "Xiao Ye is here to help. I need his help to stabilize your arm. Then I can help you set your bones."


    Chen Xin nodded, looked at the little leaf, and then looked at Zeng Liu again, indicating that Zeng Liu would start.


    Zeng Liu didn''t dare to talk nonsense and didn''t dally. He took out what he wanted from the medical box still on the table and let Chen Xin sit out for a little convenience. After he and Xiao Ye operated, he said to Xiao Ye, "Xiao Ye, help me hold his arm."


    Xiao Ye nods and comes to Chen Xin without saying anything. Under Zeng Liu''s instruction, she holds Chen Xin''s fractured right hand and signals to Zeng Liu that he is ready.


    Zeng Liu once again untied the bandage and splint on Chen Xin''s arm, sprayed two times with the pain spray in the fracture area, and saw Chen Xin confirming that he felt no pain. Then he said, "you have been injured for two days, and the position of the bone is not right before. So when I am going to be bone setting, I need to break your broken bone back in place. It may be very painful. I hope you can bear it."


    Chen Xin was psychologically prepared for this. He nodded and didn''t say anything. He just urged Zeng Liu to say, "let''s go."


    Zeng Liu took a deep breath, sank his heart, and said to the little leaf beside him, "little leaf, you must grasp his arm, use your greatest strength, don''t move, understand?""I know, sister Liu." Xiao Ye nodded and grasped Chen Xin''s arm with more strength.


    See two people are ready, Zeng Liu this just said to Chen Xin: "I started."


    With that, Zeng Liu grasped Chen Xin''s broken arm and began to pull. Although


    sprayed the pain spray, Zeng Liu''s action still made Chen Xin feel a sharp pain, and instinctively wanted to pull his hand back.


    Xiao Ye quickly stabilizes Chen Xin''s arm to prevent him from pulling it back. Zeng Liu also changes his posture, holds Chen Xin''s wrist, and says to Xiao Ye, "Xiao Ye, you can jam his elbow, hold the bone, and then pull it back!"


    After Xiao Ye pinched the bone of Chen Xin''s right forearm near the elbow joint as Zeng Liu said, Zeng Liu pulled forward the wrist joint of Chen Xin''s right hand, straightening Chen Xin''s originally bent right arm.


    As Zeng Liu straightens Chen Xin''s arm, Chen Xin feels a sharp pain in his right hand. It''s like someone wants to tear off his hand. He can''t help crying out.


    But it''s obviously not over. After straightening Chen Xin''s arm, Zeng Liu didn''t let go. Instead, he continued to hold his wrist with one hand, while holding the other hand with his fingers at the place where he broke the bone to realign it.


    This is no doubt more painful than just pulling apart the broken bone. Chen Xin almost grabbed the gun on the table and killed the two men. But he still gritted his teeth to resist the pain of digging out the bone, but his forehead was in a cold sweat.


    once again sprayed the pain spray on Chen Xin''s arm, and again pinched Chen Xin''s bone with his fingers, confirming that when the broken place was pinched back to the right place, Zeng Liu only released Chen Xin''s wrist and signaled the loose leaf''s hands.


    "This is me and an old doctor of traditional Chinese medicine. Without X-ray, I can''t guarantee that the reset is completely in place." Zeng Liu wiped the sweat on her forehead. Just now, she also sweated: "but it''s just a fracture of the ulna and radius. It''s relatively easy to reset. As long as it''s fixed well, it can basically achieve clinical healing in 4-6 weeks. After three months, it''s basically sharp. Even if it''s not in place, it won''t affect the function of your arm."


    Chen Xin nodded slightly to show his understanding, but the severe pain just now made him speechless. He just motioned to Zeng Liu and wrapped his arm up again.


    Zeng Liu picked up the splint that had been removed from the table and readjusted the posture of the splint. Then he asked Xiao Ye to help and fix Chen Xin''s arm again.


    Once again, the bandaged arm was hung in front of Chen Xin''s chest. However, this time, Chen Xin was more comfortable and beautiful than before, and his arm was successfully repositioned, which was not as curved as before.


    Chen Xin is very satisfied with this. Although he still plans to wait until the next refuge to go to the hospital and the doctor for a review, he is very satisfied that he can do so under the current conditions.


    "You did a good job, thank you." Chen Xin calmed down and said thank you to Zeng Liu.


    Zeng Liu looked at Chen Xin and saw that he seemed to be in a good mood. Then he bit his lip and summoned up the courage to ask him, "can you take us out of here? You promised before that as long as I cure your arm, you can take us out of the county. "


    Chen Xin looked at Zeng Liu and looked at her for a few seconds. After staring her pale, he nodded and said, "it''s OK to take you. If you don''t have a large number of people, you can also take them with you, but those guys who were knocked down by UAVs are not included."


    When Zeng Liu heard Chen Xin say this, he took a long breath and quickly said, "thank you! We don''t have many people, just me and Xiaoye, and old Tang and sister Ning! Those people are not with us. "


    Chen Xin nodded to show his understanding, and then said, "I''ll stay here for about a day to repair. After you pack up your things, I''ll take you away."


    "Thank you. Thank you so much!" Zeng Liu is excited, and she can finally leave this place that has become a dead city. She is full of gratitude to Chen Xin from the bottom of her heart.


    One side of the small leaf seems to understand, also rushed to Chen Xinmang express thanks.


    Chen Xin didn''t care about their thanks. He just waved his hand and said, "go back and pack up your things. Don''t take any unnecessary things with you. Take your necessary personal belongings with you. We''ll leave one day later. I won''t wait for you."


    "We know that. Please rest assured that it will not cause you any trouble!" Zeng Liu was only grateful to Chen Xin and changed his address to honorific. He didn''t have any thoughts or dissatisfaction because of Chen Xin''s request.


    After Chen Xin waved that they could go, Zeng Liu and Xiao Ye got out of the car gratefully and went back to the place where they lived to inform Old Tang and sister Ning of the good news.

 Chapter 239

    After correcting the broken bone, Chen Xin''s injury was managed properly, but the pain caused by bone setting was so severe that Chen Xin took a long rest to recover.


    He told Zeng Liu that he would stay for one day, not to wait for them to pack up, but to repair the antenna damaged in the avalanche.


    At the same time, Chen Xin also plans to maintain his car.


    Although the system did not find any problems before self-test, it suffered from an avalanche and was completely buried under the snow. Therefore, we should do a comprehensive inspection and maintenance to avoid possible problems.


    And along the way, Chen Xin found that although the car is very good in all aspects, it still lacks polishing and adjustment, and some parts still need to be adjusted.


    Of course, these adjustments refer to the adjustment of the parts and state of the vehicle, which does not require Chen Xin to spend the survival.


    It''s just that this kind of adjustment needs professional knowledge and understanding of the vehicle. Chen Xin only knows a little bit about it, just making some minor adjustments.


    Previously, Chen Xin was injured in his arm, and because of the outdoor environment, he was not very good at repairing his car, so the radar antenna was always broken.


    But now that the arm has been treated and the underground parking lot is still quiet, Chen Xin will be able to repair the damaged radar antenna.


    From the stairs of the living cabin to the second floor, which is strictly only half floor, it can be used as the second double bed. You can sleep or sit on the ground, but there is no space to stand up. There is also an exit to the roof.


    The roof exit itself is designed for the maintenance of the top of the vehicle, so even if Chen Xin injured a hand, he can easily climb to the roof.


    However, looking at the snow on the top of the car, Chen Xin scratched his head. After thinking about it, he went back to the car and took back the three drones, leaving only one of them with a searchlight to provide lighting. Then he took a broom and went back to the top of the car.


    The snow on the roof of the car was swept with a broom, and Chen Xin came to the position of the antenna.


    Looking at the radar antenna that was obviously smashed and twisted, Chen Xin knew that the antenna was hopeless even if he didn''t know any mechanical knowledge.


    Although half of it is still intact, the other half has been twisted into a ball. If you want to repair it, you have to replace it or rebuild it.


    However, for Chen xinla, this is not too difficult to solve. It will cost 100 survival points to upgrade the "damaged radar antenna" to "improved radar antenna", and the repair work will be completed.


    After repairing the antenna, Chen Xin went back to the car and turned on the radar again while taking back the last UAV.


    Chen Xin was relieved to see that the radar was back online and working again. The damage to the radar in the past two days made him feel very unaccustomed.


    Now that the radar has brought the surrounding environment under control again, Chen Xin feels at ease. At least he doesn''t have to smear the road any more. He only relies on UAVs to detect the road conditions.


    In today''s black environment, even if the UAV has an infrared camera, its detection range is extremely limited. Compared with the radar which can scan a radius of five kilometers, it can obtain too little peripheral information.


    If there was a radar, Chen didn''t need to install a life detector on the UAV. He could search zengliu''s life signals directly by using the radar.


    After repairing the radar, Chen Xin scanned the surrounding area again with the radar, and sure enough, he made a new discovery.


    It is true that this county town is almost abandoned, but in the radar scanning area with a radius of five kilometers, Zeng Liu is not the only group of survivors.


    About three kilometers away from Chen Xin''s location, Chen Xin also detected other life signals.


    Other survivors? Chen Xin is not a good judge, but he has no intention of contacting them.


    More is better than less. Zeng Liu helped Chen Xin to treat her arms. Since she promised to take them to the next refuge, Chen Xin thought it was better to keep her promise.


    But he didn''t have much love. He felt that everyone had to save him.


    So Chen Xin just sent a UAV to fly by and take a turn to see what happened to the other side.


    Seeing that the other party seemed to be a little better than Zeng and Liu, Chen Xin didn''t care about them any more.


    As for whether these people can survive, Chen Xin thinks it has nothing to do with himself.


    Now there are too many people in the world who need to be saved. Chen Xin doesn''t feel that he can save everyone. He has neither the strength nor the idea.


    If you see one, you want to save one. Sooner or later, you will put yourself in.


    If you meet someone who can help you, Chen Xin won''t be stingy with his help, but Chen Xin won''t do this kind of thing that he is in a hurry to help others.


    Instead of paying attention to the survivors, Chen Xin adjusted the radar to alert mode and found a toolbox to adjust the state of the vehicle.Although Chen Xin is very satisfied with all aspects of the car''s performance, there is still room for adjustment.


    So Chen Xin found out his toolbox and planned to take this opportunity to adjust it.


    However, when Chen Xin opened the cabinet of his toolbox, he was surprised to find that there were three sets of spacesuits and a pistol left by Zhang Chengguang and Zhang Chengguang in the cabinet. There was a piece of paper under the pistol, which seemed to be left by Zhang Chengguang and Zhang Chengguang.


    Chen Xin picked up the paper and wrote a message from Zhang Chengguang on it. In general, it means that these three sets of spacesuits and pistols are given to Chen Xin as a gift of thanks for helping them along the way. He also specially reminded that spacesuits can be used as protective clothing to provide enough life support for Chen Xin, while the pistol told him not to take them out casually as a way to save his life when necessary Self defense weapons.


    Not only that, but also the notes on how to wear the spacesuit, how to check, how to supplement oxygen and so on.


    With this piece of paper, Chen Xin was somewhat moved and felt that he had not saved the three people in vain.


    Chen Xin just scratched his head at the things in the cupboard. He didn''t know how to deal with them.


    It''s easy to handle the gun. It''s OK to put it in the cabinet. Just find a place to put it away properly, but the spacesuit is actually a little chicken ribs.


    Of course, space suits can be used as protective clothing. This kind of clothing prepared for the space environment can be put on the ground, which is simply a defense surplus.


    But this thing as a protective clothing has a big problem is heavy.


    A suit of spacesuit should be at least 20-30 Jin, which is not included in the weight of extravehicular backpack and thruster.


    In space, of course, this weight is nothing. No matter how heavy things are in zero gravity environment, we can''t feel it. But the problem is that when we put it on the ground, the weight of 20-30 Jin is a little hard.


    It''s OK to wear it for a short time, but if you wear it for a long time, it will feel like wearing a suit of armor and doing weight-bearing exercises, which will consume more physical strength.


    More physical consumption means more physical energy consumption, and more food is needed to recover.


    It''s very important to save every bit of consumption for this kind of food, which is very precious in the last days. If you can, you should try to avoid such unnecessary consumption.


    And now although the environment is very bad, but also really do not use a suit of spacesuit to do protective clothing, both waste and unnecessary.


    But it''s Zhang Chengguang''s kindness. Although such a suit is very expensive now, it''s astonishingly expensive. Whether it''s the materials on it or the attached machinery and equipment, even before the disaster, the cost of each suit is astronomical.


    It''s normal for an in cabin suit like this. If it''s an extra cabin suit, it costs about 200 million yuan.


    Therefore, Zhang Chengguang and Chen Xin were able to leave three sets of spacesuits. They really wanted to thank him sincerely, and they also gave him a very heavy gift.


    It''s just that this gift is a little too heavy for Chen Xin to know what to do with these things.


    How about upgrading to a more high-tech spacesuit?


    Chen Xin thought of this idea, but he gave up.


    To upgrade, it''s not to be a spacesuit. After all, Chen Xin can''t go to space now, and he can''t use space level protection at all. When he has the ability to go to the sky, he must have no shortage of spacesuits.


    So the biggest use of these three spacesuits is to upgrade to the direction of protective clothing. Maybe the power armor Chen Xin always wanted is on these three spacesuits.


    However, at present, this is just an idea. Chen Xin''s demand for protective clothing is not urgent, and he has no desire to buy new equipment.


    So he just checked the three sets of protective clothing, locked them back in the cabinet, and then carried the toolbox to adjust the car.


    When Chen Xin adjusts his car, Zeng Liu and others in the underground garage are also packing their things.


    Because Chen Xin said that they were only allowed to bring their own important belongings, Zeng and Liu were turning out their belongings and sorting them out one by one.


    Although he wanted to take it away, he also felt that he could not put it down, but Zeng Liu was still making a choice, taking only the most important or necessary things.


    Perhaps because of the desire to leave here immediately, whether Zeng Liu or Lao Tang, or sister Ning who is still ill, she is very happy. The little leaf on one side is even more excited. She turns around from time to time, picking up and putting down all kinds of things. She doesn''t know what to do.


    In fact, even Zeng Liu and Lao Tang were very excited, but they had to be more or less stable, and they had to prepare to take things away, so they didn''t have the same feelings as Xiao Ye.


    But even so, their hearts are also happy and excited to be able to leave here and start a new life.

 Chapter 240

    In Zeng Liu''s busy life with some anxieties and expectations, the day passed quickly.


    They also packed up what they needed to carry and were ready to start.


    Zeng and Liu can pack up their things and leave the dead town, but those tramps who were injured in the leg by Chen Xin are not so lucky.


    Although Chen Xin didn''t take their lives, and their injuries were not affected by their own treatment, neither Chen Xin nor Zeng Liu intended to take them with them.


    So the only people who can finally leave with Chen Xin are Zeng Liu and the four of them.


    This obviously made the group of vagrants feel particularly jealous, but they were hurt and deterred by the force of UAV. Even if they wanted to do anything, they didn''t have the ability to do it, and they missed the opportunity.


    Maybe in the evening when they were packing up, the group of vagrants could surprise them. Maybe they could do something else, but it was obvious that they were completely frightened by the previous UAV attack.


    After all, it''s just a group of indecent vagrants. A pistol can hold them down, not to mention two drones that can really shoot.


    Zeng Liu and his family left smoothly. Although they had a little too many things to take with them, Zeng Liu and his family went back and forth several times. They carried all the things up and piled them beside Chen Xin''s car.


    Looking at the things Zeng and Liu brought up, Chen Xin couldn''t help frowning and said, "I said you only need to carry the necessary personal belongings, right? These things are not personal belongings in any way. "


    "These are our clothes, food, and some..." Zeng Liu wants to explain.


    Although they have made trade-offs, they still have the idea of breaking up their family, and they are reluctant to lose it. They want to take away a lot of things they have accumulated.


    However, in Chen Xin''s view, these things are just a pile of rags.


    Because most things, by definition before disaster, are really crappy.


    There are empty cans, reusable plastic bottles, self-made simple filtration devices And a bunch of pots and pans, and even a sack of charcoal.


    Although we can understand the reasons why Zeng and Liu were reluctant to give up these things, and understand that these things were important resources for their survival before, Chen Xin still can''t let them take all these things with them.


    So without letting Zeng Liu finish talking, Chen Xin interrupted her, shook her head and said, "there is not such a big place in the car for you to take these things, food, clothes and necessary personal belongings. You can only carry these three types of things."


    With that, he turned and got into the car, without paying any attention to Zeng Liu.


    Hearing Chen Xin''s words, Zeng Liu and old Tang couldn''t help looking at each other, and holding sister Ning''s little leaf on one side was also at a loss.


    Finally, sister Ning, who was a little weak, said, "do as he said. We have no choice, and we really don''t need to bring so many things."


    Seeing that elder sister Ning said so, Lao Tang and Zeng Liu just counted a lot of things they had brought up, cleared out the unnecessary things and prepared to give them up.


    However, it''s hard to give up all the things they''ve collected or made before.


    Fortunately, both Lao Tang and Zeng Liu know the importance of things. They can''t offend Chen Xin for such a lot of things and lose the chance to leave the city.


    So they still cleaned out most of the unnecessary things, leaving only some of the food they collected, the clothes of the four and some of the things they carried with them, which re sounded the door of Chen Xin.


    "It seems that you have made a choice." Chen Xin took a look at the four people who had rearranged their luggage, and then nodded with satisfaction.


    Chen Xin got out of the car, took four people to the back of the car, opened the trunk and said, "put your luggage here."


    Seeing this, Zeng Liu and Tang quickly put the things they wanted to carry into the trunk.


    When they put their luggage into the trunk, old Tang couldn''t help looking at the things in the trunk. He was obviously surprised by the food in the trunk.


    They haven''t seen so much food for a long time since the county population moved to the three towns.


    But Lao Tang and Zeng Liu didn''t have any idea about these things. They just envied Chen Xin for having so much food.


    Put the luggage, old Tang and Zeng Liu this just and small leaf and Ning elder sister together on the car.


    On the bus, Chen Xin looked at the four people who got on the bus and said to them, "I promised Zeng Liu that she would help me with my injuries. I took you to the new shelter, so I let you get on the bus."


    "Thank you for your help. We''ll get off when we get to the new shelter. It won''t cause you any trouble." Zeng Liu sees Chen Xin say so, make clear to him in a hurry oneself four people won''t depend on don''t go.


    The other three also hastened to follow suit, indicating that they did not mean to stay.Chen Xin nodded slightly, then continued: "I''m going to Anhui Province next, and the next county is estimated to have the same population as this county, so I may send you to Anhui Province."


    "Anhui Province?" Old Tang could not help but ask, they are all from Hubei Province, if they want to go to Anhui Province, this is really something they did not expect.


    After all, it''s not before the disaster. If you go to Anhui Province, you will probably never come back to Hubei Province.


    Chen Xin didn''t say anything about this, but after explaining his next course of action, he didn''t say anything more: "the table here can be put down to make a double bed. In addition, people can sleep on it from the back and on the top. You can sleep in these two places at night.


    If there''s nothing else, I''ll start right away. The road is bumpy. You''d better find a place to sit down. "


    With that, Chen Xin did not care about the four people any more. He went to the cab and started the car to start.


    Seeing this, Zeng Liu and others also sat down on the sofa.


    This is the first time that the four of them took a bus after the disaster, or fled from the dead County town, which makes them feel as if they were separated from each other.


    "Sister Liu, have we left the county?" Feel the car under the body moved up, small leaf side holding Ning elder sister to rest on the sofa, at the same time to Zeng Liu uncertain inquiry.


    Zeng Liu nodded and said with certainty, "Mr. Chen Xin has promised to send us to the next shelter. We can really leave here."


    Hearing Zeng Liu say so, Xiao Ye really felt that she could finally escape from the abandoned County town with a happy smile on her face.

 Chapter 241

    The car carrying Zeng Liu and others drove out of the county, feeling the shaking of the car. Although the outside of the car was dark, and there was no window on the car, Zeng Liu and others still had an inexplicable mood.


    Some of them are reluctant to leave. After all, all four of them are local. They have lived here before.


    Although the county is now deserted, it is still their hometown. They were born here, grew up here, studied here and worked here


    It can be said that almost all the memories in their lives are closely related to the county and the land.


    But now in order to survive, they have to leave their hometown where they have lived for almost a lifetime, which inevitably makes them feel a little different.


    After all, in terms of the current environment, once they leave, it is estimated that they will be hard to come back in their lifetime. I am afraid that this abandoned County town is also hard to be inhabited.


    Maybe the country will have a plan for post disaster reconstruction in the future, but it is far away for Zeng Liu and others. Even at that time, it is hard to say that the reconstructed county is not what they remember.


    Among the four, sister Ning was still sick and weak. Before the car left the county, she couldn''t carry it. Zeng Liu and Xiao ye put her on the sofa to have a rest.


    Because Xiaoye is relatively young, she doesn''t feel much about this kind of thing. She is more happy to leave this hopeless place and worried about sister Ning who is still ill.


    However, because Zeng Liu got the medicine from Chen Xin in time, sister Ning was actually much better, but she was not completely well, and she was still very weak.


    But by such a interruption, Zeng Liu''s sadness also subsided a lot, more is the expectation of the future.


    Because this is Chen Xin''s car, Zeng Liu and others do not dare to walk around. Although they are looking forward to a new life in the future, they are still bored.


    The four of them have been living together for a long time, and they are actually very familiar with each other. After a few simple conversations on some topics, we can''t help falling into a state of speechless.


    Zeng Liu can''t help but let Tang look at Xiao Ye and Ning Jie. Then she comes to the cab and looks at Chen Xin, who is driving. She wants to thank him.


    "Mr. Chen Xin, thank you very much. If it wasn''t for your help, we couldn''t have the chance to leave the county. Thank you very much!" Zeng Liu said thank you to Chen Xin very seriously.


    She could imagine that without Chen Xin''s help, nine out of ten of them would not be able to pass this time. The vagrants had obviously planned to swallow them, and their fate would be really hard to say.


    Although Chen Xin was frightening at the beginning and frightened Zeng Liu, Zeng Liu was still full of gratitude for Chen Xin after thinking about it with expectation and anxiety all night, and now he really left the county.


    Chen Xin didn''t feel much about it. He nodded at Zeng Liuwei: "it''s a little help. Besides, you also helped me to treat the fracture. It''s an equivalent exchange."


    Chen Xin really doesn''t feel much about rescuing Zeng Liu. Just like rescuing a cat and dog by the roadside, it''s nothing more than a matter of lifting one''s hand. He may have some sense of achievement, but it''s hard to feel too excited.


    Zeng Liu seems to realize that Chen Xin doesn''t have any special emotions, but it doesn''t affect her gratitude to Chen Xin.


    It''s just that Chen Xin always looks so cold and light, and Zeng Liu doesn''t know how to thank him.


    Because of the shaking of the car body, Zeng Liu was sitting in the back seat of the cab. She didn''t know what to do, but she didn''t want to go back to the back to sit with Lao Tang and them. In addition, she was curious about Chen Xin''s car, so she stayed in the cab.


    Looking at the radar screen on the console, Zeng Liu asked Chen Xin curiously, "Mr. Chen Xin, is this radar? What are the dots on it? "


    "Light spot?" Hearing Zeng Liu''s question, Chen Xin glanced at the radar screen beside him and then replied, "it should be other survivors. The radar can scan signs of life and moving objects within a radius of five kilometers. It seems that there are more than a few of you in this city."


    When Zeng Liu heard Chen Xin say this, she immediately opened her eyes. She did not expect that there were other living people in the deserted county.


    He wanted to ask about these people, but Zeng Liu didn''t have a position to ask. After thinking about it, he could only give up these ideas and asked Chen Xin, "Mr. Chen Xin, where are we going next?"


    "The next step should be to go along G318 national highway to the next county, but the population of your county has all migrated, and the next county may be in the same situation." Chen Xin has no expectations.


    After all, the two counties along the way are counties with inconvenient transportation. In the past, there was G318 national highway, and the new expressway was built. It''s not that there was any obstacle, but the economic development was not as fast as other places.


    But after the disaster, with the snow blocking all the roads, these small counties without railway transportation security have been in a state of internal and external difficulties, traffic cut off.It''s not to say that the road is completely impassable. After all, Chen Xin got through by himself, which may be a little more difficult for others. But if we want to keep the traffic smooth, we can still do it for Yanguo, but the cost is too high.


    After the disaster, there is a shortage of resources such as fuel. In addition, it takes a lot of manpower and material resources to maintain a road. If it is not a very necessary traffic artery, it is not worth spending such a huge cost to maintain it.


    For the high-level officials in Yanguo, it is obviously more cost-effective to maintain the smooth railway transportation with larger capacity and easier maintenance than to maintain the smooth road transportation.


    So it''s not surprising that all the people in such a small county moved to the nearby big cities. After all, the high-level officials of Yanguo could not let the people in these small counties live and die on their own.


    Although that''s what he said, Chen Xin obviously wants to go further if he wants to put Zeng Liu and others down in the next refuge. After all, there are only two counties along the way. If the population is withdrawn, the road will be deserted.


    Thinking of this, Chen Xin asked Zeng Liu, "I''ll send you to the next shelter. Although it may be in Anhui Province, what are your plans next?"


    "Intend to..." Hearing Chen Xin''s question, Zeng Liu shook his head after thinking about it: "I don''t know. I just thought about how to live. I really didn''t think about the future."


    "Then you can start thinking about it now." Chen Xin took a look at Zeng Liu and said nothing more.

 Chapter 242

    Compared with the underground parking lot where Zeng and Liu used to live, Chen Xin''s RV has a smaller space, but its comfort level is completely different from that of the sky and the ground.


    Zeng Liu and his family never even thought that they could enjoy a warm and comfortable room in the last days, and they could drink warm and clean hot water without worrying about what to eat tomorrow, and eat delicious food rather than just food.


    This is all they have never thought of.


    Before boarding Chen Xin''s car, Zeng and Liu were already in a situation of material shortage.


    Food is collected from abandoned buildings, water is filtered after melting ice and snow, and fuel is collected from the outside to chop wood


    Although the bonfire can provide them with hot food, in this freezing environment, even if a cup of boiling water is poured out, it can form ice even before it falls to the ground. The so-called hot food is just a little better than eating cold food.


    In such an environment, it''s a matter of gratitude that they can have a bite to eat. They don''t dare to expect anything to be able to eat well and have enough to eat.


    This also led to the fact that the four of them had been malnourished for a long time. The reason why sister Ning was so seriously ill also had a lot to do with their lack of food and clothing.


    But in Chen Xin''s car, even the most humble shelter, standard food and energy bars are already very good food for them, filling their hearts with gratitude and happiness.


    All four of them are trying to put more food into their stomachs, giving people the feeling that they will not have another meal after eating. Chen Xin can''t laugh or cry when he looks at them eating.


    However, Chen Xin can also understand that if a person is half hungry for a long time and can''t find any food, he can suddenly get a full meal. Even if the food is ordinary, it is precious to him. He will worry that he won''t have another meal after eating.


    "Brother Chen Xin, are these foods really the standard rations in the shelter? Isn''t the food wonderful? " Chewing an energy bar, Xiaoye asks Chen Xin curiously. He can''t believe that he can eat so much in the shelter.


    Chen Xin shook his head, pointed to the energy bar in his hand and the food on the table, and said: "the standard food in the shelter is only the energy bar and the mushroom rice in front of you. As for other things, they belong to me extra."


    "I said, if everyone in the shelter could have such good food, we would not..." Little leaf with a smile on his face, also want to say something, one side of the old Tang kicked him under the table, let him shut up.


    Chen Xin didn''t pay attention to Tang''s small actions. Besides the standard food in the shelter, he also brought some dehydrated vegetables with him before. After boiling with water, he made a little seasoning. It didn''t taste bad.


    Generally speaking, although the food is still very simple, it''s not bad in this end of life. Especially considering that Ning Jie is a sick woman, Chen Xin cooked some rice porridge for her.


    As for other things, it''s not that Chen Xin was stingy and didn''t bring them out. It''s just that there is no need and no reason to be extravagant.


    What''s more, these people have nothing to do with Chen Xinfei. It''s reasonable to give them a little food to eat, but it''s too much to give them more supplies to have a big meal.


    Fortunately, Zeng Liu and others have been very satisfied with such food, and there is no extra extravagance.


    But while eating, Chen Xin still asked Zeng Liu the question: "what are you going to do next?"


    "When we get to the next shelter, we''ll get off. It won''t cause you any trouble, Mr. Chen Xin." Hearing Chen Xin''s question, Lao Tang didn''t hesitate as much as Zeng Liu did. He naturally replied, "there''s no plan in the world today. To live well is the biggest extravagance and plan."


    "Alive?" Chen Xin nodded and said nothing more.


    For these four people, old Tang and sister Ning are police officers. Although they are only assistant police officers, they are still members of the system. When they get to the next refuge, it''s not difficult to find a job.


    Not to mention Zeng Liu, in today''s eschatological environment, anyone with medical skills is a scarce resource, and is not worried about finding something to do.


    On the contrary, Xiaoye is just a child who graduated from junior high school. If there was no such disaster, he should go to senior high school now.


    At the next refuge, he is the only one who really needs to think about the future and the way ahead. After all, even in the last days, books still need to be read.


    However, it''s not Chen xinlai''s turn to worry about this. He just needs to put these four people in the next shelter, and I believe the officials there will properly settle and handle their affairs.


    After all, according to the tradition of Yan state, even if the world is over, as long as there are conditions, children still have to go to school.


    What''s more, according to the plan released by the state before the disaster, small and medium-sized shelters should have primary education, large shelters should have primary and secondary education, and cities, counties and regions should have high school education. For children like Xiaoye, it is no problem to continue to study.It can''t be said that in three years'' time, he will take part in the college entrance examination and continue to study in University.


    For Yanguo, even if it is the end of the world, education is absolutely impossible to relax. Moreover, maintaining the operation of the education system and continuously cultivating new talents for the country are also the top priority of accelerating the post disaster reconstruction.


    Otherwise, if children do not study, there will be a talent gap after a long time, which will be a huge obstacle to the future reconstruction of the country and the recovery of social production.


    In many eschatological works that Chen Xin has seen before, there is a lack of description in education, which is one of the important factors for the collapse of social order, the decline of human morality and the despair of the whole world in those eschatological works.


    Before the disaster, there are only a few people who have received a complete education and have the skills and knowledge, and most of them are adults. As time goes by, most of them will die because of age, disease and other reasons.


    If the rest of the next generation has not received a complete education, it will be difficult to continue to maintain the existence of civilization, and human society will soon fall into a primitive and ignorant state.


    So for the end of the world, the maintenance of the education system is more important than before the disaster.


    After a silent meal, sister Ning, who is still ill, is helped to have a rest by Xiao Ye. Lao Tang takes over the task of cleaning the table and washing the dishes. Zeng Liu is responsible for checking Chen Xin''s head wound and changing his dressing.


    Carefully opened the wound gauze, Chen Xin forehead wound healing is not slow, looks better than before.


    "The wound healed well. I changed the medicine today. I''ll change it again in two days. I don''t need to change it later." Zeng Liu explained the recovery of the wound to Chen Xin while skillfully changing the medicine.


    Chen Xin didn''t say anything. He just looked at Zeng Liu and expressed his gratitude.


    Zeng Liu quickly finished treating the wound on Chen Xin''s forehead, changed the medicine for him, and bandaged it up again.


    After dealing with the wound on his forehead, Zeng Liu examined Chen Xin''s fractured right hand again.


    Compared with the wound on the forehead, the healing of the fracture is much slower, and there is no medicine to use. What Zeng Liu can do is spray some external medicine for swelling and pain relief on Chen Xin''s arm, so that the congestion on his arm can be removed, and some swelling and pain can be reduced.


    As for the healing of the bone itself, it can only rely on the natural healing of the bone after his arm is fixed. There is no medicine that can effectively promote bone growth and healing.


    Even the treatment of fractures in hospitals is mainly bone setting and reduction. The reason why some people need medicine is that their bones are reset by surgery. Drug treatment is to promote the healing of the surgical edge, not the bone itself.


    Although Chinese medicine sometimes uses some medicine such as ointment to help and promote bone healing, the effect is very limited, otherwise there will be no saying that it will hurt the bones and muscles for 100 days.


    "Does the fracture still hurt? Do you feel any discomfort? " Zeng Liu asked Chen Xin, did not rashly open the bandage and splint.


    "The place of fracture is a little swollen and painful, but there is no discomfort." Chen Xin described his feelings and tried to move the fingers and wrists of his right hand: "if you move your fingers, there will still be a little pain."


    "It''s better not to use this hand as much as possible. At present, it''s just to help you reset the bone. The broken bone has not healed. When the muscle is pulled, it is likely to cause dislocation again." Zeng Liu reminded Chen Xin.


    Chen Xin nodded and accepted her reminder.


    However, Zeng Liu was still a little worried and asked Chen Xin with concern: "by the way, Mr. Chen Xin, what''s your next schedule? Your arm needs further treatment. I suggest you find a shelter with a professional doctor for further treatment. You put us down in the next shelter, and you hurt your arm all by yourself? "


    "There should be no problem. It''s just a hand injury. It won''t affect my life." Chen Xin didn''t feel that there was any obstacle to this. Although he could only use his left hand, there would be a lot of inconvenience in life, but there was no big problem: "my next trip is to meet my parents in Anhui Province, and then I will return along the same road. If there is no refuge in Hubei Province, I can only put you in the refuge in Anhui Province."


    "So..." After listening to Chen Xin''s words, Zeng Liu seemed thoughtful, nodded and did not speak again.


    Chen Xin didn''t like it either. Seeing that Zeng Liu had checked himself, he got up and went back to the cab, started the car and continued the journey.

 Chapter 243

    The next journey can be described as lacklustre. Although there were four more people on the bus, it didn''t make Chen Xin''s journey much different.


    Compared with Zhang Chengguang and his three astronauts, Chen Xin didn''t trust Zeng and Liu too much, so he didn''t ask them to help drive.


    Moreover, among the four of them, Lao Tang can drive, but Lao Tang obviously does not have the professional skills to recognize radar scanning images. Even if he is allowed to drive, he is not very good at using the equipment on Chen''s new car, which may cause danger.


    But relatively speaking, it''s not without benefits. At least some people do dishes and cook. For Chen Xin, who has hurt his hand, it saves him a lot of things.


    Chen Xin''s original plan was to put Zeng Liu and others down in the next county. However, just as he had expected, this county was the same as Zeng Liu''s previous county. All the people were evacuated, and there were only a few survivors in the county.


    Chen Xin didn''t have the idea of dealing with these people, and didn''t contact them. He just scanned the county with radar, and when he saw that there were no people in the county, he turned around and continued his journey.


    "Mr. Chen Xin, are there any other shelters ahead?" Sitting in the co driver''s seat of the cab, Zeng Liu saw that Chen Xin didn''t stay in the county, and asked him with some trepidation.


    Zeng Liu was very afraid. He was afraid that there was no other refuge. Chen Xin sent them all the way. It is very likely that there will be no next refuge at the end of the road.


    However, Chen Xin was not worried about this. He just shook his head and said, "it is estimated that there is no refuge in Hubei Province, but there should be a refuge in Anhui Province. The place I''m going to is an important city in Anhui Province. Even the county below has a railway, so it should not move all the people away. "


    Hearing what Chen Xin said, Zeng Liu was still worried, but he didn''t say anything more. He just nodded and closed his mouth.


    In fact, this is also the worry of Old Tang and elder sister Ning. After recovering, elder sister Ning, who used to be the backbone of the four, called Zeng Liu and old Tang together to discuss what they should do next.


    No matter Zeng Liu or old Tang and sister Ning can feel that Chen Xin doesn''t mean to take them in. It''s only because Zeng Liu has treated him.


    Now I haven''t driven them out of the car, but I think there''s a shelter in front of me. I''ll just put them down at that time. Besides, Chen Xin''s injury hasn''t healed, so I need someone to take care of him.


    When they just left, they didn''t have this kind of worry, just immersed in being able to leave the dead County town, but along the way, they didn''t find a new refuge, which inevitably made their expectations continuously decline and became uneasy.


    After all, Chen Xin has always said that Zeng and Liu have cut off contact with the outside world for a long time. They don''t have a concept of these situations, so it''s not strange that they think there may be no other shelters.


    Zeng Liu''s previous inquiry also wanted to find out about Chen Xin. They were afraid that Chen Xin would drive them out of the car. In that case, the four of them would not survive.


    But it is clear that Zeng Liu''s trial did not produce any results.


    This can''t help but cast a shadow on Old Tang and elder sister Ning''s heart.


    Only Xiaoye, because she was younger, didn''t feel much about it. On the contrary, she was worried that she had to continue to study when she got to the shelter.


    Chen Xin doesn''t know Zeng Liu''s worries and anxieties. Even if he does, he is unlikely to comfort them or do anything.


    In the final analysis, Chen Xin''s idea of Zeng Liu is still just to help them, save them if he can, but he doesn''t care about anything, let alone how much he cares about them.


    Although the snow made the mountain road difficult, Chen Xin arrived at the border of Hubei and Anhui after several days'' delay.


    "It seems that there is no new refuge in Hubei Province, so we are going to Anhui Province next." Chen Xin looked at the roadside by snow buried more than half of the monument, helplessly shook his head.


    "Is there no refuge in the capital of Anhui Province?" Zeng Liu anxiously looked at the boundary pillar beside the road and the damaged and almost invisible slogan "welcome to Hubei province again". His mood became very complicated and worried.


    Chen Xin shook his head. He didn''t worry about it. He just said to Zeng Liu, "don''t worry about it. There must be shelters in Anhui Province. Moreover, Hubei Province moved the population of the two counties because of the inconvenient transportation. The places I want to go in Anhui Province are railways, highways and airports. The transportation is very convenient. There is no need to move the population.


    And if there is no new shelter, it''s a big deal that you stay in my car for a while. When I return, I''ll pass by three towns and put you in three towns. "


    "Three towns Is that really OK? " Hearing Chen Xin mention the capital of Hubei Province, Zeng Liu couldn''t help looking a little excited.


    Although there are no other refuges, the three towns still have a deep position for the people of Hubei Province. In Zeng Liu''s mind, if there are any refuges in Hubei Province, the three towns must be one of them."There''s nothing wrong with it, and nothing wrong with it. Anyway, I''ll send you to an official shelter that''s still in operation." Chen Xin set the tone for the incident and said nothing more.


    It''s just about where to put Zeng and Liu down. For Chen Xin, it''s not a big problem to put them down even if he takes them back to Sanzhen.


    After all, after receiving his parents, there may not be enough space in the car, and he doesn''t want Zeng Liu and his parents to have too much contact and interaction.


    Thinking about these things, Chen Xin drove his car across the border between Hubei Province and Anhui Province and entered Anhui Province.


    Anhui Province is Chen Xin''s hometown. Although he went to Hunan Province with his parents when he was four years old and lived there for nearly 30 years, his hometown is always his hometown.


    Although Chen Xin''s impression is that his hometown is a poor and shabby place. Every time he comes back for the new year, it''s always inconvenient here and there, but his relatives have lived here for generations.


    The elders who love them and other relatives in the family all live here.


    Although I don''t like this place very much, it is Chen Xin''s hometown anyway.


    And the most important thing is that Chen Xin''s parents are here. He will take them back anyway.


    After crossing the provincial boundary, the road is still the same bumpy and difficult, which is not different because of the boundary between Hubei Province and Anhui Province.


    In particular, Chen Xin''s road, whether in Hubei province or Anhui Province, is a mountain road between mountains. It was good before the disaster, but now the snow capped mountain situation is just like Chen Xin''s tracked vehicle. Ordinary cars have no traffic capacity at all.


    "Mr. Chen Xin, do you know where to find your parents?" Zeng Liu is a little curious about this problem.


    After all, as we all know, transportation and communication have been cut off for a long time. Chen Xin traveled through Hunan, Jiangxi, Hubei and Anhui provinces to pick up his parents. He spent so much energy and cost, and even broke his hand. How can he be sure that he will be able to pick up his parents?


    Chen Xin nodded and said, "before the disaster, I still had contact with my parents. Their location was in the mountains of their hometown, where a small shelter was built.


    The shelter was built according to my suggestion. Food, drinking water and heating were all considered. Basically, it was the same as the shelter I lived in. If I could survive, my parents would also survive.


    And the people who live in that shelter are all relatives from my hometown. They can take care of my parents if they have any problems. There won''t be any problems. "


    Hearing Chen Xin say so, Zeng Liu didn''t ask any more, just nodded, didn''t say anything to hit Chen Xin.


    Although in Zeng Liu''s heart, he still felt that Chen Xin''s parents might not be alive, or that he could receive his parents smoothly.


    Before Zeng Liu met Chen Xin, although her companions were only Lao Tang, Ning Jie and Xiao Ye, as well as a group of vagrants who were not companions, they were not the only ones.


    But after the evacuation of the county, they were short of food and clothing, materials, medicine and effective medical treatment, so that many people died of illness, starvation and freezing.


    Zeng Liu clearly remembers that one of his friends fell asleep and didn''t wake up the next day.


    And more companions didn''t even have the chance to sleep like this. Zeng Liu once watched a child cry and said to himself that he didn''t want to die, but he died.


    So it''s not surprising that Zeng Liu is pessimistic about whether Chen Xin''s parents can survive, because she has seen too many tragedies, and her heart has long been pessimistic about the world.


    However, Zeng Liu is not the kind of person who can''t speak. This kind of cold water words can''t be said directly to Chen Xin.


    After all, if Chen Xin gets angry and drives them out of the car directly, Zeng Liu can''t afford the price.


    So after skipping this topic, Zeng Liu was silent.


    Chen Xin doesn''t know what Zeng Liu is thinking. If he does, Chen Xin may really drive her and her companions out of the car, even though Chen Xin is not a cruel person.


    As a matter of fact, Zeng Liu''s worry about Chen Xin had been there, but before he saw his parents, Chen Xin was full of hope and kept the idea of things going in a bad direction to a minimum.


    In any case, people always expect things to develop to the good side, no one will expect things to develop to the bad side.

 Chapter 244

    "Why are there so many mountains in this area?" Sitting in the co driver''s seat, Zeng Liu grabs the armrest beside him, feels the bump and tilt of the car body, and asks Chen Xin nervously.


    I can''t help but feel nervous, because they are now driving on a slope, and the whole car body has tilted at least 15 degrees. It feels like they are about to slide down.


    Chen Xin doesn''t feel nervous about this. He is very confident in his car''s grip and side slope capacity. Even on a 30 ¡ã slope, the car won''t slide down. What''s more, it''s only 15 ¡ã now.


    However, Chen Xin answered Zeng Liu''s question and explained to her, "because this area belongs to the eastern extension of the Dabie Mountains, and the main peak of the Dabie Mountains is in this area. It is normal to have many mountains. Otherwise, the revolutionary base of Hubei, Henan and Anhui would not have been established here, and Liu Deng''s army would not have entered the Dabie Mountains during the war of liberation."


    "Is this Dabie Mountain, too?" Zeng Liu certainly knows the name of Dabie Mountain. In fact, the county where she was originally located is also within the scope of Dabie Mountain, but she didn''t expect that it was out of Hubei Province and still within the scope of Dabie Mountain.


    "What''s so strange about this? The Dabie Mountains cover Hubei, Henan and Anhui provinces, with Wuhan in the West and Nanjing in the East. It''s a large mountain range, not a mountain." As an Internet writer, Chen Xin doesn''t think that Dabie Mountain is as simple as a mountain.


    "I know that! But - ah Zeng Liu is saying something, but the car body suddenly shakes, so that everything she wants to say is swallowed.


    The shaking of the car body returned to the level. It turned out that the shaking just now was that they had passed the slope and re entered the gentle road.


    Interrupted by this, Zeng Liu did not continue to discuss the Dabie Mountains with Chen Xin. Instead, he asked him, "Mr. Chen Xin, is your hometown in the Dabie mountains? Where we''re going is also in the mountains? "


    "It''s me, not us. I''ll put you down at the next shelter." Chen Xin reiterated this point, and then explained: "my hometown should be considered as the remnant of the Dabie Mountains strictly, but you are right. The place I want to go is really in the mountains."


    Hearing Chen Xin say so, Zeng Liu bit his lip and didn''t know what he was thinking.


    After pondering for a while, he asked, "are we going to continue to go east?"


    "Yes, continue to the East, through the county, it is into my hometown of Shuzhou where the region." As Chen Xin said, he called out the map on the console and explained the next journey to Zeng Liu: "now we are in Yuexi County. I will pass through the county. If there is a refuge there, I will put you down there. After that, I will continue to go east and enter Shuzhou County along the provincial road."


    Looking at Chen Xin''s map and the route marked with red lines on the map, Zeng Liu suddenly asked Chen Xin, "Mr. Chen Xin, what if the population of Yuexi County moved like the county we passed before?"


    "Then I will take you to Shuzhou county." Chen Xin took a look at Zeng Liu. She didn''t know what she was thinking, but she gave a positive answer.


    After getting Chen Xin''s reply, Zeng Liu nodded and said nothing more.


    It seems that things are indeed developing in a bad direction. Chen Xin in Yuexi county still hasn''t found an official refuge in operation.


    This made Zeng Liu''s heart cast a shadow, for their future is also more and more not optimistic.


    Chen Xin doesn''t think there is any problem with this. Yuexi county is the same as the two counties in Chenxin road of Hubei Province before. It''s located in the mountainous area. Except for roads, there is no other means of transportation in the county. In today''s environment, it''s not impossible or strange to move people out.


    As for his hometown, Shuzhou County, Chen Xin is not very worried about being relocated, because there are railways in Shuzhou county.


    As long as the railway transportation is not cut off and materials can be continuously imported, then the refuges in this area can still operate without considering population migration.


    After all, population migration can ensure the survival of most people in a certain area, but it will also cause great pressure on the Immigrating Area, so if it is not necessary, the country will not easily migrate the whole population in a certain area.


    So although Zeng and Liu seem very uneasy and worried about their future, Chen Xin doesn''t care about these things.


    All he wanted to do now was to finish the last part of the journey and get to his hometown to pick up his parents.


    Therefore, Chen Xin did not continue to delay in Yuexi County, where there were few people, but directly passed through the city and headed for his hometown.


    In Chen Xin''s memory, the village where his relatives live is not too far from Yuexi County. In the past, it took only half an hour to drive to Yuexi County. Even now, it takes less than a day to walk there.


    Walking on the road that has made him feel more and more familiar, Chen Xin''s mood has become a little excited and expectant.Although he didn''t see his parents for a long time before, he could contact them by phone or other means before the disaster, and Chen Xin could know the situation of his parents at any time. It was something that Chen Xin had never experienced before that he completely cut off contact with his parents for more than half a year.


    This makes him more and more eager to see his parents, so that he drives faster and faster, which makes Zeng Liu have to remind Chen Xin to slow down.


    Reminded by Zeng Liu, Chen Xin slowed down the car again and said sorry to her: "sorry, I''m a little excited."


    "I can understand. If it was me, I would be very excited." Zeng Liu''s words were a little sad. Although she did not experience the difference between her parents and family, her parents and family had all stayed in the county.


    Chen Xin nodded slightly, only to adjust his mood, then said: "I will go to see my parents first. Before the disaster, the last message they gave me was that they and my relatives live together in the refuge in the village, hoping that it has not been moved, otherwise we will have to walk another day to enter the county."


    "Mr. Chen Xin, don''t you want to go to the county?" Zeng Liu looks at Chen Xin and feels that he seems to have some rejection of the county.


    "Not to mention, the county still has to go, at least I will send you to the county." Chen Xin didn''t explain anything. He just gave a simple answer, and then he focused on driving again.


    Zeng liuruo thought, but she didn''t say anything more, so she was silent.


    The road from Yuexi county to Chen Xin''s hometown is not long. Although the mountain road is rugged, it took three or four hours for Chen Xin to arrive at the town nearest to the mountain village where his parents and relatives live.


    To Chen Xin''s surprise, he is ready for no one in the small town. However, this small town has a refuge in operation.


    And what surprised Chen Xin in particular was that the people in the town were several times more than he thought, and even there was more than one shelter.


    Chen Xin''s car into the town, of course, was found by the people in the town, we are vigilant to watch these two unusual tracked RV, quickly called the police in the town.


    "Hello, comrade. Where are you from?" After Chen Xin stopped, the police quickly came to the window. When Chen Xin lowered the window, they asked him.


    "I''m from Hunan Province." Chen Xin answered the police''s question, in order not to cause unnecessary misunderstanding, Chen Xin also took the initiative to explain: "my hometown is also here, come back to pick up my parents in the past."


    "Did you drive here from Hunan Province? Now in this kind of environment, you can actually drive the car, which is also a good skill! " When the police heard Chen Xin say that he was from Hunan Province, they immediately showed surprise and admiration to him.


    Chen Xin didn''t say much about this. He just laughed. Although it was not easy to walk all the way, and he broke his arm when practicing himself, there was no need to talk about this with the police.


    "My family is from XX village. What''s the situation there now? I remember that before the meteorite fell, my family told me that there was a shelter there. " Chen Xin to the police to listen to the situation of relatives in his hometown, the heart can not help but nervous.


    When the police heard Chen Xin''s inquiry, they didn''t find it strange. They just thought for a moment and then replied, "XX village? Oh, the situation over there seems to be OK. The county will transport the materials to the town every month, and then the town will send them to these villages in batches once a week. To be honest, these shelters in the village are more comfortable than those in the town. There are too many people in the town. "


    Hearing this, Chen Xin finally put down his heart. A big stone hanging in his heart fell to the ground. What he was most afraid of was that something had happened to his hometown village, or that the people in the village had been moved away.


    After letting go, Chen Xin was also attracted by another thing mentioned by the police, so he asked curiously, "Why are there so many people in the town? I don''t remember there were so many people in the town before, did I? "


    "You remember correctly, there were more than 20000 people in the whole town before, and most of them were still in the countryside and villages. There were really not many people in the town." The police nodded, and then explained to Chen xinlue helplessly: "but before, in order to prevent disasters, the country moved all the population of coastal cities. Because Anhui Province is next to Zhejiang Province and Jiangsu Province, a large part of the population of these two provinces moved to Anhui Province. Even our broken town now has more than 50000 people, and three light shelters have been built We are also very busy


    Hearing this, Chen Xin also shook his head and sighed. Then he asked the police, "now if I want to go to XX village, is the road still workable?"


    "The road is impassable, but if you go along the river, you can still get to XX village. In the way of your car, it''s no problem." The policeman took a look at the track under Chen''s new car and gave him a thumbs up.

 Chapter 245

    According to the previous police guidance, Chen Xin drove the car to the beach near the town.


    "It seems that this place has become a passageway." Looking at the fresh ruts on the river, Chen Xin couldn''t help laughing.


    Maybe it''s getting closer and closer to his parents that Chen Xin is in a very happy mood.


    Zeng Liu and others have been put in the refuge in the town by Chen Xin. Among the four, sister Ning and old Tang are very happy. Although they are still nervous and nervous about the strange environment, they can meet the official refuge which has a large population and is still in operation. It''s a dream for sister Ning and old Tang to settle down.


    Xiaoye has no doubt about it, but she is anxious about going to school again.


    Only Zeng Liu seems to be a little uncomfortable and hesitant when he gets off the bus.


    Chen Xin doesn''t pay attention to this, or even if he finds out Zeng Liu''s abnormality, he won''t say anything. After all, he is just four strangers who were saved by hand. It''s very kind of him to send them here.


    So after handing the four of them over to the official staff of the town, Chen Xin drove away in a hurry.


    Walking along the ruts on the river, Chen Xin can''t help but think of the story his mother told him. When his mother was young, she lived in the mountains of her hometown. At that time, there was no road. When it snowed, the mountains would be closed. It was very inconvenient for villagers to get in and out of the mountains. They could only walk on the river after the river was frozen.


    But that was Chen Xin''s mother when she was a child. The river has rarely been frozen these years, and the village has long been connected with roads. No one has walked across the river in winter for many years.


    But now, it''s clear that the river is once again functioning as a transportation line.


    Up along the river, as the river on both sides gets narrower and narrower, Chen Xin knows that he is about to get home.


    Although he has never lived here since childhood, home does not mean a place or a house, but a place where there are family members.


    Only when there is a place where one''s family is located can one be called home, which is the end result of one''s soul.


    Finally, Chen Xin drove his car to the mountain village where he lived.


    Although it is covered with snow, Chen Xin can still identify the general terrain.


    There is a small river crossing the village. Although it has been filled with snow for a long time, Chen Xin can still vaguely identify the small river where he caught crabs as a child from the results of radar scanning and the pictures taken by the camera of the UAV.


    The field beside the ditch is often talked about by my grandfather. When he was young, he planted sesame seeds in the field, although later the land had changed its ownership.


    The small flat land in the village used to be a rice farm. It''s used to dry rice in the village, but there are fewer and fewer people drying rice these years.


    Chen Xin parked his car at the head of the village. There was no spacious road in the village. In the past, he could drive in, but now Chen Xin''s big car is obviously impossible to drive in.


    After parking the car, Chen Xin changed into protective clothing. Although he said that one hand was broken and it was not convenient to wear clothes, Chen Xin still used both hands and mouth. He soon put the protective clothing on his body and put on a protective mask and was ready.


    Opening the door, Chen Xin holds a snow stick in his left hand and puts on his specially prepared snow walking boots. He walks towards the village with a snow stick in one hand.


    It seems that in order to be able to accept the supplies from the town, the village swept away a piece of snow on the Bank of the river. The snow in this place is not so thick. Chen Xin is not particularly troublesome when he walks, but occasionally he can''t stand steadily and needs a snowstick to support his body.


    Even so, he soon went to the village.


    The village has long been different from what Chen Xin remembers. All the houses are buried in snow. Even the ancestral hall, which is the most important place in the village, the old house left over from the Ming Dynasty, is now crushed by snow and completely buried under it.


    In addition to these, the biggest difference is that there is a hill covered with snow next to the village, which was originally a mountain depression field. The snow on the ground just extends here, so that Chen Xin can judge that this is the refuge of the village without thinking about it.


    Chen Xin can see that this is not the kind of shelter that is completely dug underground. Instead, half of it is dug to repair the building part of the shelter, and then the excavated soil layer is covered on the building, so as to quickly build a thick enough soil layer in this simple way, rather than digging a hole in the mountain in a more expensive way.


    In fact, Yanguo was able to resettle the majority of the population in three months, and the shelters built in this way accounted for a large part of the credit. After all, a considerable part of the rural population lived in such shelters.


    Chen Xin walked along the road to the gate of the shelter. There were ruts and footprints on the ground. Chen Xin could see that it was left by people coming in and out of the shelter. Moreover, the snow on the ground was not frozen or covered up. It was obvious that these footprints would not last long.However, Chen Xin did not care about this. Instead, he stood in front of the gate of the shelter, took out the radio station and yelled at the radio according to the communication channel that the town police had told him before.


    "Is anyone here? Can anyone hear me? " Chen Xin shouts to the radio in his native dialect. Although the cold wind around him and the snow blown by the wind almost instantly turn him into a snowman, even if he is wearing protective clothing, it''s cold, but Chen Xin still feels hot in his heart.


    He is about to see his parents. How can he not be excited!


    Soon, a voice came from the radio. The familiar local accent made Chen Xin so excited that he could hardly hold the radio station in his hand: "which one? what''s the matter? Didn''t the supplies of this week just come in the morning? "


    "Second uncle, it''s me, ah Xin! Open the door Chen Xin exclaimed excitedly. Of course, he could hear his second uncle''s voice.


    "Ah Xin? How did you come back, you little boy? " The second uncle was obviously surprised by Chen Xin''s sudden appearance. A stampede and shouting voice came from the radio: "you wait, I''ll call people to open the door!"


    Chen Xinxin waited anxiously, his chest thumping, and he tried to breathe to calm himself a little bit.


    Second uncle didn''t let Chen Xinjiu wait. Soon someone opened the door of the shelter. What appeared in front of Chen Xin were his long lost relatives and his parents.


    "Dad! Mom! I''m back! " Chen Xin cried out and finally burst into tears.

 Chapter 246

    When Chen Xin is welcomed into the shelter, all the relatives of his family gather around him and sit down in the hall of the shelter. Then everyone asks Chen Xin all kinds of questions.


    "Ah Xin, how did you come back? It''s snowing so hard outside. Did you suffer a lot when you came back from Hunan Province? "


    "Ah Xin, what are you doing back here? Can''t you stay there so far? "


    " did you eat? I''ll make you something to eat, but there''s nothing good. Ah Xin, you''ll make do with it. "


    Facing the concern of relatives at home, Chen Xin felt that he couldn''t cope with it. He responded one by one with a wry smile. Chen Xin then asked his parents, "Mom and Dad, are you ok? Is there any problem here? "


    "What''s the problem? It''s not the same all over the country now. Your father and I are in good health. Some eat and some sleep. There''s no problem." Chen Xin''s mother responded to Chen Xin''s question, but suddenly noticed Chen Xin''s sleeve and asked nervously, "son, where''s your hand?"


    With that, Chen Xin''s mother nervously touched Chen Xin''s sleeve.


    In order to avoid his mother''s worry and tension, Chen Xin quickly opened the neckline of the protective clothing, hung it on his chest, exposed his arms, and explained: "it''s OK, here it is! I had a bit of trouble on the way here, and I just had a bit of a broken hand. "


    "Why are you so careless! Does it hurt? Why didn''t you get a cast? " Seeing her son''s broken arm, Chen Xin''s mother felt distressed and cared.


    "It''s OK. It''s already dealt with. I didn''t meet the hospital on the way, so I didn''t have a plaster cast, but I got a splint. It''s OK." While coping with his mother''s concerns, Chen Xin quickly brought the topic to the focus of his return: "Mom and Dad, I''m here to pick you up."


    "Take us back?" When Chen Xin''s parents heard what he said, they were stunned and couldn''t help looking at each other. They didn''t know what Chen Xin meant.


    Seeing this, Chen Xin quickly explained to his parents, "well, the shelter I built in Hunan Province has now been transformed and has..."


    When Chen Xin explained to his parents, Zhang Chengguang and Zhang Chengguang returned from Sanzhen to the space launch center in Sichuan Province with the isotope thermoelectric battery Chen Xin gave them and the image data of Chen Xinbei rubbing nuclear battery recorded by Hubei Provincial researchers.


    This is one of the three most important space launch centers in Yanguo, because it is located in the strategic rear of Sichuan Province, which is the most important of the three launch centers.


    Because of its unique geographical location and natural environment, Sichuan Province has been an important strategic depth since the founding of the state of Yan. It has concentrated a large number of important military industry and scientific research institutions, and many important military facilities of the state of Yan have also been set up in the mountains of Sichuan Province.


    It can be said that since the founding of the people''s Republic of China, many military facilities and underground projects have been built in Central Sichuan for strategic deep use. The most famous mountain city has built a large number of air raid shelters since the Anti Japanese war.


    After the disaster, many military facilities and underground projects that had been sealed up were reopened, and a large number of scientific research institutions that migrated from coastal areas to inland areas were sent here.


    So it''s only natural that they were sent here after they learned that Zhang Chengguang and Zhang Chengguang had returned to the ground and carried important observation data.


    In fact, Zhang Chengguang spent most of their time training here. Even the spacecraft they set out to carry out the mission was launched from here. It can be said that returning here is like returning home.


    However, they didn''t have time to feel the warmth of their home. As soon as they returned to the space launch center and handed over the isotope thermoelectric battery and video materials to the scientific research department, the chief engineer of the space center called them to the office.


    "I''m sorry, Xiao Zhang, you just came back and didn''t let you rest, so I called you to ask." The white haired chief engineer and Zhang Chengguang exchanged greetings, and then directly asked the main question: "I have read the report submitted by Hubei Province. If what is said in the report is true and the isotope thermoelectric battery you brought back has such exaggerated performance, it is of great significance to the whole country!


    I specially called you here to ask your views on Comrade Chen Xin.


    You are the people who have been in contact with him for the longest time, and you know more about the situation. Your opinions are very important! It will also serve as an important reference for us to make contact with Comrade Chen Xin and formulate response plans and measures, so you should tell us all the details of your contact with him, the more detailed the better! "


    Hearing what the chief engineer said, Zhang Chengguang and his colleagues were all a little nervous, but they quickly sorted out their ideas and recalled all the details of their contact with Chen Xin.


    Fortunately, before they came back, they had expected that their superiors would inquire about them. They had done some induction and collation, but they were not at a loss. They didn''t know how to start.


    However, the three did not expect that the chief engineer would ask the question in person. They thought it would be someone from the relevant department who would make a record.The chief engineer''s personal interview also made them feel the importance of the superior and the state.


    After sorting out his ideas, Zhang Chengguang took the lead in saying: "according to our contact with Chen Xin in recent days, I think he is a cautious but warm-hearted man. In the current eschatological environment, he is willing to help others, which is enough to show his good character.


    And he''s willing to tell us that he can make isotope thermoelectric batteries, and let''s record the whole process of making batteries. I think this is enough to show that he is willing to contribute to the country. "


    Zhang Chengguang wanted to say a few good words for Chen Xinduo, so his speech was biased, but he did not cover up the facts.


    Zhang Yao, on one side, is relatively the one who has the most contact with Chen Xin among the three. After Zhang Chengguang finished, he also said, "Chen Xin claims to be acquired scholar syndrome. I don''t think this is necessarily true, but he should not lie. He really only knows how to do it, but he can''t say why."


    After listening to them, the chief engineer felt thoughtful, but he didn''t say anything. Naturally, there was a professional analysis department to do these things. So the chief engineer just thought about it and looked at Zhao Wu and asked him, "Xiao Zhao, what''s your opinion?"


    "Chen Xin has pride in his heart. Before, Hubei provincial officials wanted to recruit him on behalf of Hubei Province, but he didn''t care about it. He also deliberately made an isotope thermoelectric battery by hand, which shows that he was arrogant in his heart." Zhao Wu expressed his views and finally added: "so I think we should have a good relationship with him and try our best to get in touch with him with an equal and cooperative attitude. If we take a high attitude, it may arouse his disgust."

 Chapter 247

    Chen Xin, who returned to his hometown, naturally received warm hospitality from his relatives. Although there was no rich material in the mountain village shelter, these relatives still took out what they could and warmly entertained Chen Xin.


    As the village head''s second uncle also specially arranged for people to clean up the room for Chen Xin, so that he can live at ease.


    But Chen Xin refused his kindness, indicating that he would not live in the shelter: "don''t bother. I came back by car. I just sleep in the car at night."


    "How can sleeping in a car compare with sleeping in a bed! Don''t say so much. I''ll find someone to make room for you, and I''ll settle down at night. " The second uncle obviously thought that Chen Xin was just driving an ordinary car, so he tried to keep him: "don''t worry, just clean up a room, it doesn''t cost anything, and the things are ready-made, or just delivered in the morning, they are all new, no problem."


    Chen Xin is really hard to say when he is asked to stay by his second uncle. He can only accept his second uncle''s kindness.


    However, he said to his second uncle that he had brought something back from the car and asked him to send someone to move it with him.


    "You said you''d come back and bring something else! Our town will send materials every week. The greenhouses you asked us to make before the disaster can collect a lot of vegetables every month. You can take them to the town to exchange things. We don''t need anything here. Keep it for yourself! " Second uncle immediately refused, did not want new things Chen.


    However, Chen Xin shook his head and said, "it''s all food. When I passed three towns on the road, some friends gave me food. I can''t finish it myself. It''s easy to break when I put it on the car. I''d better give it to my family! I have it myself


    Hearing Chen Xin say so, second uncle is not good to insist on anything, had to let Chen Xin''s two cousins to help move things.


    The two cousins had no idea about this. They pulled a sledge out of the shelter and went out with Chen Xin.


    "The plough was sent by the town. It was said that it was used to transport materials and travel for each refuge, but in fact it was rarely used, because now it can only be pulled by people, and each refuge has no surplus materials to support the animals pulling the plough. The transportation of materials is barely enough. It''s not enough to go out." Chen Xin and these two cousins are not very familiar, but one of the big cousins is very enthusiastic about Chen Xin.


    The second cousin also said politely to Chen Xin that since Chen Xin had hurt his hand, he would watch them move later.


    In this regard, Chen Xin just smile, did not say anything, then with two cousins came to his car at the entrance of the village.


    Seeing Chen Xin''s armored tracked RV, the two cousins were obviously stunned and looked at Chen Xin in surprise. They couldn''t believe that this is what Chen Xin said.


    "Ah Xin, is this your car?" Although the big cousin''s face was covered with a mask, the surprise in his eyes could not be concealed: "how much is the car! No wonder you can drive back from Hunan Province. With such a powerful car, you are really not afraid of snow


    Chen Xin didn''t say anything, but with a modest smile, he opened the trunk of the car and said to his two cousins, "I changed the car myself. It didn''t cost much. Besides, what''s worth now is materials."


    Hearing Chen Xin say so, the two cousins put away their surprise and went to the trunk to move things.


    However, looking at a lot of things in Chen Xin''s trunk, they all looked at Chen Xin, waiting for him to explain which can be moved.


    "This, this, and this..." Chen Xin ordered two boxes of shelter food, a bag of dehydrated vegetables he made himself, and dried meat and dried fruit he got in Sanzhen: "move these back."


    "Ah? So much back? " The second cousin obviously didn''t expect Chen Xin to be so generous and let them carry so many things.


    "It''s nothing. These are all from friends. If we don''t have to leave food rations for our return journey, it''s nothing to give them to everyone." Chen Xin is very generous about this, just a little food, he really doesn''t care.


    Seeing that Chen Xin is so generous, the two cousins look at each other, but it''s not easy to say anything more. They decide to move things back first. As for whether to leave things or send them back, it''s up to the elders to make a decision. At most, the two of them just go again, and it doesn''t cost much.


    After Chen Xin moved the things he ordered to the plow and tied them with the ropes he brought, the two cousins waited for Chen Xin to close the trunk before dragging the plow back.


    The things on the plough are obviously a little heavy, especially when they are pulled by manpower in such snow. Both cousins are panting, but they are very happy. Even if the elders feel that they can''t leave so many things, they will certainly leave some of them.


    This is a powerful supplement to the village, a small refuge, even if only a part of it is left behind.


    The three returned to the shelter. Sure enough, the second uncle and several relatives in charge expressed dissatisfaction with Chen Xin''s bringing so many things. They didn''t even see what Chen Xin was bringing, so they asked him to take them back.


    But Chen Xin just shook his head and said with a smile, "you can keep these things, second uncle. For me, these things are really nothing. If I want to find a friend, I can get them again."After several times of persuasion, Chen Xin''s father finally opened his mouth, and the second uncle accepted it.


    But accepted the thing, the second uncle a check, immediately by Chen new big pen surprised.


    Of course, two boxes of shelter food is nothing. This kind of food accounts for a large proportion of the supplies sent by the town every week, and it is also the main food reserve in the shelter at present.


    Dehydrated vegetables are hard goods. Although the shelter in the village also has greenhouses and can produce a lot of vegetables every month, most of these vegetables are taken to the town by the second uncle to exchange for other materials, and there is not much left to eat.


    The air dried meat is even more exaggerated. For the second uncle, they haven''t seen real meat for more than half a year.


    "Ah Xin, it''s too expensive! We can''t have it! " Second uncle looked at the large box of dried meat, although he was also very greedy, but still the first time to return things to Chen Xin.


    In this regard, Chen Xin deliberately cold face at him, said to the second uncle: "said to accept and push back, the second uncle you look down on me?"


    Speaking of this, the second uncle was unable to give way, so he had to send things to the warehouse for storage.


    But Chen Xin''s parents were surprised that Chen Xin suddenly took out so many things. They asked Chen Xin, "son, where did you get so many things?"

 Chapter 248

    It''s always a good feeling to go home. Even if the conditions are a little poor, it''s still a happy thing for Chen Xin to be able to meet his familiar family again.


    Especially in today''s environment, if you are separated from your relatives or friends, it may be hard to see them in your life. After all, not everyone has the condition of Chen Xin, who can drive across four provinces to meet his family.


    "The conditions are a little rough. Don''t give up, Xin. Have a good rest first." After dinner, the second uncle took Chen Xin to his room and explained to him.


    Two cousins have already told him that the car Chen Xin drove back is a very luxurious and large saloon car. Compared with that car, the conditions in the shelter are much worse, which makes the second uncle feel a little embarrassed that he didn''t entertain Chen Xin who came all the way back.


    Chen Xin didn''t mind laughing at this, and said to his second uncle, "it''s nothing. It''s already very good. We all know what kind of world it is now. It''s very good to have a place to sleep and to be able to fill your stomach so as not to freeze to death or starve to death."


    Hearing Chen Xin say so, the second uncle also laughed, as if to put down some of the burden, and Chen Xin simply said a few polite words, told him to have a good rest, then left the room.


    Seeing his second uncle leave, Chen Xin is a little relieved. He has to say that the enthusiasm of his relatives makes Chen Xin a little overwhelmed. In particular, his second uncle is a man who wants to save face. This has not changed even now that he is in the last days.


    Chen Xin looked at his room, but he couldn''t help raising eyebrows.


    The room arranged by the second uncle for Chen Xin is a standard room temporarily vacated, which is no different from other people''s rooms. It''s just that Chen Xin sleeps alone, unlike other rooms, which are obviously shared by two people.


    The furnishings in the room are also very simple. There is a table with a lamp on it and a chair in front of it. There is a high and low bed with a steel frame. The bunk on the lower floor is covered with new and thick bedding. There is nothing else.


    "Don''t you have anything extra like a water bottle?" Chen Xin looked around and felt that the conditions here were even more shabby than before when he saw Qin Lan''s room in the city, and some necessary daily necessities were in a state of material shortage.


    Although the second uncle let people vacate the room, spread the bedding, and brought the table lamp, there was no basin, towel, and hot water for washing face and feet in the room, which was enough to show that the living conditions here were not very good.


    In particular, the second uncle also said that this week''s supplies were only sent to the town in the morning.


    This makes Chen Xin want to do something, at least to improve the living conditions of his relatives.


    However, this is not something that can be done for a while. Even with the system upgrade, Chen Xin can''t say that he simply smashes the survival to upgrade the refuge.


    You know, it''s a lot bigger than his own refuge, and there''s a lack of materials. If you want to survive, you have to survive. For Chen Xin, it''s an astronomical amount of survival.


    It''s not that Chen Xin is reluctant to invest so much, but that there''s no need to waste so much. Chen Xin can upgrade some infrastructure for this refuge as he did for upgrading his refuge, so as to improve the living conditions here, instead of directly smashing down a large amount of survival and upgrading the whole refuge.


    After all, it''s because he''s not so rich.


    Just as Chen Xin was thinking about these problems, Chen Xin''s second aunt also brought him a thermos full of hot water, as well as a brand-new washbasin and towel and a hot water bag, which made Chen Xin feel embarrassed and feel like he had caused a lot of trouble to his relatives.


    Shaking his head, Chen Xin decided to have a good night''s rest.


    Although one hand is not very convenient, Chen Xin still irons his feet with hot water and pours a hot water bag for himself, so he is ready to go to bed.


    The temperature in the shelter is a little low. Although it''s good to keep warm indoors, it''s still very cold in the room without heating equipment. Going to bed early is also a way to save energy and keep warm. After all, the quilt is too warm.


    The next morning, Chen Xin woke up very early, but he was not so much awakened by himself as by cold.


    Strictly speaking, the temperature in the room can''t be too low, but even if there is no heat in the quilt, the hot water bag in my arms is already cool, but it feels a little cold.


    This kind of situation is also a different experience for Chen Xin. After the disaster, he almost always stayed in his refuge. In fact, he did not experience the impact of severe cold.


    After all, whether his shelter or the armored RV he lives in on the way here, they all have perfect heating and insulation facilities, so that Chen Xin can sleep comfortably when he is sleeping, rather than being frozen.


    However, it is obvious that the shelter in my hometown has no such good conditions. It is an unexpected but reasonable thing to be cold awakened.Since he was awakened by the cold, and the quilt was not very warm, Chen Xin had to get up, put on his clothes with one hand, and washed with his head, which was not awake, and because of the cold weather, he left the room.


    The rest of the shelter apparently got up early and started the day.


    In fact, most of the relatives in their hometown are older. Before the disaster, most of the younger generation wandered outside or moved to the county or city, or even stayed in the town. As a result, most of the people in this shelter are older now.


    Looking at such a scene, Chen Xin can''t help thinking about whether he can do something for them or help them improve their life.


    With this in mind, Chen Xin came to his parents'' room.


    Chen Xin''s parents have got up and are cleaning up their room. Yesterday, Chen Xin had talked with them about taking them back to Hunan Province, but they obviously hesitated.


    Chen Xin''s parents, of course, are convinced that they can have better living conditions and live with their son when they go back. Their hesitation is mainly due to the fact that they can''t let go of their relatives.


    After all, once you leave, you may not be able to come back, and these relatives in your family may not be seen for a lifetime.


    Chen Xin''s parents are different from Chen Xin. Chen Xin didn''t grow up in his hometown when he was a child, but went to Hunan Province when he was about four years old. He didn''t have deep feelings for these people and things in his hometown.


    But Chen Xin''s parents were born and raised here. They grew up here, studied here and got married here. After Chen Xin was born, they went to Hunan Province because they wanted to give Chen Xin a better life.


    It can be said that for his hometown, Chen Xin''s parents are far more affectionate than Chen xinlai.


    That''s why they are hesitant and reluctant.


    Chen Xin didn''t find it strange or unexpected. He didn''t urge his parents. He was quite sure that they would go back to Hunan Province with him. It just took a little time to make a decision.


    "Ah Xin, you have broken your hand. Have you seen a doctor? What did the doctor say? " Chen Xin''s mother, who was making the bed, saw that Chen Xin was still hanging an arm, and her clothes were not very stretched, so she helped Chen Xin pull his clothes and asked him about his arm injury.


    Chen Xinshun asked his mother to help him with his clothes and replied: "on the way here, I found a doctor who knows how to set the bone for me. But there is no X-ray and I don''t know how the specific situation is. At present, there is no big problem."


    "Then you go to the county hospital to have another examination and have a good treatment." Chen Xin''s father suggested to Chen Xin, looked at Chen Xin''s arm, and said to him, "arm fracture is not a joke. It''s safe to go to a doctor for a good look."


    Chen Xin saw that his parents were so concerned about him, so he nodded and agreed.


    In fact, the county is quite far away from the town. It takes more than half an hour to drive before the disaster, and most of them are mountain roads. In this case, even if you can go to the county, it will take a lot of time.


    Therefore, if Chen Xin wants to go to the county to see his hands, he has to start in the morning.


    Chen Xin told his second uncle about it, and his second uncle also agreed. Although there is no doctor in the town, especially after a large number of people have migrated, the medical and health level in the town has been improved, but it is mainly for common diseases.


    More serious injuries like fractures still need to go to the county hospital for treatment.


    However, it is obvious that both his second uncle and Chen Xin''s parents are worried about Chen Xin''s driving to the county, so after some discussion, they decided to let one of Chen Xin''s cousins drive for him, and Chen Xin''s parents will also go to the county with him.


    After breakfast, when they came to Chen Xin''s car at the entrance of the village, they were also shocked by Chen Xin''s car. Even Chen Xin''s parents could hardly believe that the armored RV in front of them was Chen Xin''s.


    Fortunately, the RV itself has the information state provided by the system, and the concept is vague. Coupled with Chen Xin''s reasonable explanation, they soon believed Chen Xin''s words.


    After getting on the bus, Chen Xin taught his brother-in-law how to drive the car, and sat down in the life cabin with his parents.


    "No wonder ah Xin, you said yesterday that you should go back to the car to sleep. Your car is more comfortable than the shelter." Chen Xin''s mother felt the air conditioning in the car and looked at the living environment in the car. She couldn''t help saying to Chen Xin, "I come here to sleep at night. Is there any place to sleep in the car? It''s so cold in the shelter that I haven''t been able to sleep well


    Chen Xin nodded and said, "at least six people can sleep in the car. There''s enough room to sleep, and you can take a bath and cook. There''s no problem at all."


    Hearing Chen Xin''s reply, Chen Xin''s mother showed a satisfied expression on her face.

 Chapter 249

    The county is a long way from the town, and Chen Xin''s brother-in-law has never driven such a big car as Chen Xin''s RV, so they drove slowly and carefully, so that they didn''t arrive at the county until the afternoon.


    There are more people in the county than in the town. Although there are not many people on the street, the huge life signs on the radar screen show that Chen Xin can deeply feel how crowded the county is now, or how many people are crowded in.


    Because of the super tsunami caused by the initial meteorite impact and the subsequent melting of glaciers in the north and south poles caused by high temperature, the southeast coastal area of Yanguo is a disaster area.


    So when Yanguo received the news that the meteorite was going to hit the blue star from the beginning, it had already started the migration plan.


    However, the time of three months is still too short. Even with the overall dispatch of the state and the cooperation of various departments, the population in the coastal areas is mainly migrated to the neighboring provinces and cities, and only a small part of the population is migrated to the central and northwest regions.


    This has led to a large number of immigrants from coastal provinces, such as Anhui Province, which is close to coastal provinces.


    Even the population of this ordinary small county in Chen Xin''s hometown has increased sharply from the previous two or three hundred thousand to nearly half a million, and the doubling of the population has almost filled the whole county.


    If the migration is not carried out according to the city, the original municipal, medical, police and other departments are well established. When they arrive at the local area, they can quickly resume operation and coordinate with the local departments. I''m afraid that the food and drink of these migrated people alone will make the immigrated area collapse completely.


    The impact of the population explosion is also reflected in the shortage of medical resources. When Chen Xin and his parents came to the original county hospital, they saw a hospital waiting hall even more crowded than before the disaster.


    Chen Xin still has a lot of familiarity with the county hospital. His grandmother used to live opposite the county hospital and was a doctor in the Department of infectious diseases in the hospital. Chen Xin''s mother also worked in the county hospital for the first time.


    Even Chen Xin himself spent most of his childhood here before he left.


    However, for Chen Xin, the outpatient building full of familiarity no longer exists, but becomes a building similar to a bunker.


    Entering through the open protective door, Chen Xin looked around to find out what was going on here.


    The county hospital has a very long history. This place has not been changed for decades since the establishment of the county hospital. Therefore, there are underground air raid shelters excavated in the 1970s and 1980s under the county hospital.


    Before the disaster, the county government made use of it, restored the original air raid shelter, deepened it, and connected it with the outpatient building and inpatient building on the surface. Then, the floors above the first floor of the outpatient building were demolished, and the remaining surface buildings were reinforced. Finally, the demolished construction waste and excavated soil layers were stacked on the surface of the building to act as buffer layers This is what Chen Xin sees now.


    At the moment, there are a large number of people coming to see a doctor in the outpatient hall, not only noisy, but also extremely crowded. Obviously, the low temperature and severe cold lead to a large number of patients.


    However, Chen Xin has not been greatly affected. Most of these people have colds or colds. There are not many fracture patients like Chen Xin, so after queuing up for registration, Chen Xin went to the underground department with his parents.


    In the past, Chen Xin''s parents had a large number of acquaintances in the hospital. Although most of their acquaintances have retired over the years, they can still find a lot of relationships by making a phone call.


    However, it''s very troublesome to find a relationship now. Chen Xin can only see the doctor according to the rules.


    Fortunately, there are not many people in the Department of orthopedics. Except for Chen Xin, there is only one who broke his leg, such as a construction worker.


    After the doctor had checked the patient, it was Chen Xin''s turn to see him.


    The orthopedic doctor was obviously much more professional than Zeng liuna, a pharmacist who had only studied orthopedics. After some inquiry and examination, he asked Chen Xin to take a film.


    "Don''t worry, young man. The orthopedic technique is good. There should be no big problem. The main purpose of taking a film is to confirm the condition of the bone and its healing. Don''t worry about it." The doctor specially comforted Chen Xin.


    After hearing what the doctor said, Chen Xin didn''t care much about himself. His parents are quite relieved. After all, it''s his son. Fracture is a great event for ordinary people.


    After a circle of film examination, the doctor also had an understanding of Chen Xin''s arm bones. He put the X-ray on the light box and explained to Chen Xin, "it''s good for the person who set your bones, but there are still some places that are not in place. It can be seen that the technique is very sophisticated but inexperienced, so we still need to adjust it again to avoid problems."


    "Still need to adjust?" Chen Xin remembers the pain when Zeng Liu set his bone last time, and his face is not good.


    "Don''t worry, it''s not a big problem. It''s just a small adjustment to make your bones reset more closely. After all, you can see from the film that there is still a gap between your two broken bones." The doctor seemed to see Chen Xin''s hesitation and convinced him: "although it''s not a big problem to put it like this, there will still be some influence. After adjustment, you can avoid that your hands are not the same length!"Hearing what the doctor said, Chen Xin hesitated, bit his teeth and nodded.


    Seeing this, the doctor quickly untied the bandage and splint on Chen Xin''s arm. According to the X-ray, he set the bone of his arm again.


    Fortunately, Zeng Liu had reset his broken bone before. Now the doctor only needs to make some minor adjustments. Although Chen Xin still feels a pain, the pain is much less than when Zeng Liu set his bone.


    After the doctor made some adjustments, he drugged Chen Xin and fixed him again. Then he said to him, "if you used to, you could go back and eat more bone soup and milk to speed up bone recovery, but now Eat more nutritious food. "


    The doctor''s expression is also very helpless, now this kind of material shortage, let alone bone soup, even milk has disappeared, can be called nutritious, that is, mouse meat and synthetic vitamin tablets and so on.


    Chen Xin also wrote down the doctor''s advice, and took the list to the pharmacy to prescribe medicine.


    I have to say that after the disaster, one thing is very good, that is, medical care is free.

 Chapter 250

    Chen Xin finished reading his arms and originally wanted to go back to the village, but it was too late. If they rush back now, it might be very late. So Chen Xin proposed sleeping in the car for a night and going back tomorrow.


    This is what Chen Xin said to his second uncle before he came here, so even if they go back tomorrow, there will be no problem.


    Let my brother-in-law drive the car to a leeward place outside the county and park it. Chen Xin turns around and goes back to the life cabin.


    In the living cabin, Chen Xin''s parents are preparing to cook. However, because they are not familiar with Chen Xin''s car, they can''t figure out where to put the things. They are searching.


    Seeing Chen Xin coming, Chen Xin''s mother quickly asked him, "ah Xin, where are your food in the car?"


    "In the cupboard above, there are still some things in the trunk. You can take them directly from here." Chen Xin said. He went to the Liuli platform and opened a small door close to the double bed behind the living cabin, which led directly to the trunk of the car.


    This is what Chen Xin prepared when he was rebuilding the car. He can not only open the trunk to get things without getting off the car, but also act as an escape passage in a critical moment.


    But so far, the only use here is the passage to the trunk, so that Chen Xin can get things from the trunk without getting off the car.


    Taking out some food from the trunk and putting it on the Liuli table, Chen Xin didn''t ask his parents to cook dinner. Instead, he took out his own Kitchenware and heated the food he wanted to eat at night on the induction cooker.


    Although the induction cooker on the Liuli table can also be used to cook some simple food, and Chen Xin has enough cooking utensils in his car, the ingredients are limited, so he doesn''t make so many patterns. He just cooks a pot of paste with dehydrated vegetables and energy bars, heats up four portions of shelter food, and matches it with a small bag of dried fruits.


    Although it looks very simple, but now, it is a good meal.


    "Ah Xin, you should eat more. If you have a broken arm, you can get better quickly." Chen Xin''s mother looked at Chen Xin''s injured right hand and couldn''t help persuading him to eat more: "in the shelter, your second aunt and aunt also raised a few chickens. I''ll go back and order some eggs to make up for you."


    Hearing this, Chen Xin was very curious and asked his mother, "is there any chicken now? How did you stay? "


    "There are only a few hens and a rooster. It''s the way your second aunt came up with. She left a few eggs at the beginning, and then hatched the chickens." Chen Xin''s mother explained to Chen Xin, "chickens eat less than big ones, so it''s better to raise them. That''s why we feed these chickens. We can touch a few eggs every day."


    Chen Xin''s mother''s introduction widened her eyes, but she also regretted that if she had done the same thing, she could raise a few chickens in her refuge now, and she could eat eggs every day. She could also provide meat for herself.


    Thinking of the smell of chicken soup and drumsticks, Chen Xin couldn''t help swallowing and asked his mother, "what kind of chicken is the second aunt raising?"


    "In general, local chickens in rural areas are raised by eating leftovers." Chen Xin''s mother answered Chen Xin''s question very casually.


    Hearing his mother say that he is a native chicken in the countryside, Chen Xin has a bottom in his heart, and understands that these chickens should be very common Chaiji.


    The so-called Chai chicken is a very common breed in the countryside of Yan country, also known as Ben chicken. It can be roughed, and has strong adaptability and low feeding cost. Before the disaster, it is one of the chicken breeds that are very suitable for family breeding.


    Although it is not as good as the white feather chicken, which can reach the slaughter standard in 40 days, Chai chicken is still a good kind of chicken. Although the maturity period of five months is a little long, it is still acceptable.


    And the most important thing is that this kind of chicken can eat anything, and the leftovers that people can''t finish eating can be used to feed the chicken, which is very easy to feed.


    You know, Chen Xin''s shelter still has the bran from the rice harvest last time, which is the best feed for chickens.


    Thinking of this, Chen Xin said to his mother, "Mom, can you help me find my second aunt and ask for some eggs that can hatch chickens? I''ll take some back, and I can raise chickens there. "


    "Where do you keep chickens? Is there a place to raise it? " Chen Xin''s mother has not agreed, but his father has doubts about Chen Xin''s words.


    Chen Xin nodded his head and answered positively: "before I came here, I upgraded the whole shelter. Many places have been transformed and expanded. Now there are places to live and raise chickens. And my greenhouse also has enough output, now there are vegetables, rice and fruit, can use rotten vegetable leaves and bran to feed chickens, no problem


    After that, Chen Xin told his parents how he used greenhouse output to exchange materials, and then transformed his shelter step by step.


    In the process of Chen Xin''s explanation, Chen Xin''s father asked him a lot of questions, which made Chen Xin almost unable to resist. Fortunately, the concept of information state provided by the system was vague, which made everything reasonable. Chen Xin made it through some explanation.


    "In that case, ah Xin, you can not only harvest a thousand jin of vegetables a month, but also fruit and rice?" After listening to Chen Xin''s explanation, my cousin couldn''t help feeling envious, so he asked Chen Xin, "can you help us rebuild this refuge? Although there is a little output in the shelter now, it''s really not high. Everyone''s life is very hard. "My brother-in-law said this not for himself, but for his two sons. The elder was in grade one of primary school, and the younger was born last year.


    As a father, of course, I hope my children can live a better life and not suffer with their parents since childhood.


    Chen Xin thought about it and said, "of course, it''s no problem, but I need to think about how to transform it, and I have to discuss it with my second uncle. After all, if we really want to transform it like this, we need a lot of materials."


    His brother-in-law''s request was exactly what Chen Xin wanted to do before, so after thinking about it, he agreed.


    However, Chen Xintong needs to consider how to transform, where to transform, and whether the upgrading of these transformations will consume survival points or upgrade through materials.


    Before thinking of a concrete and feasible plan, Chen Xin will not rashly try to transform the refuge in his hometown.


    After all, the impact of this transformation will be his relatives, Chen Xin does not want to act rashly.

 Chapter 251

    After a night''s rest, Chen Xin, his parents and his cousin, who is in charge of driving, return to the refuge in the village.


    Back in the shelter, naturally, there was a lot of concern. After Chen Xin dealt with it, she found her second aunt and told her that she wanted to take some chicks back.


    "It''s easy to say, but Xin, can you take the chicken back? It''s so cold now, it''s easy for chickens to freeze to death! " The second aunt expressed her worry and took Chen Xin to the chicken farm in the shelter.


    The second aunt opened the door of the chicken farm, and a different heat gushed out from the slightly cold air in the shelter, which made Chen Xin''s eyes turn sideways.


    This chicken farm is transformed from an ordinary room. There are about seven or eight hens and one rooster in it. A chicken nest is built with bricks and asbestos tiles in the corner, and an electric heater is placed on the other side.


    This is the first heater Chen Xin saw after he came to the shelter.


    "All the chickens are here. It''s OK for you to take the chickens back to raise them. It''s OK to give you two hens. But on such a cold day, I''m afraid your chickens will freeze to death if you can''t take them back." The second aunt opened the baffle at the door of the chicken farm and went into the chicken farm. While touching the eggs in the chicken nest, she complained to Chen Xinban: "now the chicken is better than others. People don''t have a fire. Instead, the chicken has to make the nest warm for it so as not to lay eggs! What kind of world do you think this is


    Listen to his second aunt''s words, Chen Xin also can only follow a smile, did not say much.


    Now what is the world, everyone knows, the second aunt is just a few complaints, do not need Chen Xin to answer her words.


    However, Chen Xin was quite sure whether he could bring the chicks back. He replied positively to the second aunt, "I don''t want to hatch the chicks either. Second aunt, you can just give me some eggs that can hatch the chicks. I''ll take the eggs back and hatch the chicks when I get back. I have heating equipment there, the temperature is not low, there is no problem raising chickens. "


    "That''s very good. It''s good to raise a few chickens. I can eat two eggs every day." The second aunt heard that Chen Xin had conditions to raise chickens, so she didn''t say much. She just asked him, "how many eggs do you want, ah Xin? Why don''t you bring an extra hen? Otherwise, it''s not easy to raise a chicken without a hen


    "It should be enough to hatch three or five chicks'' eggs, mainly male and female, which will be better." Chen Xin put forward his own requirements.


    "Then I''ll choose ten eggs and a hen for you. Go back and build a nest. Keep warm so that the hens can almost hatch." The second aunt nodded, put the eggs in a basket, gave them to Chen Xin, and cleaned up the chicken manure on the chicken farm again. Then she took Chen Xin away from the chicken farm.


    Together with the second aunt, Chen Xin sent the harvested eggs to the storeroom. Looking at the small storeroom, he could not help frowning: "second aunt, there are not many things here! Is that all you have here? "


    "Quite a few! Other villages around us are not as good as us. " The second aunt said with great emotion, but also affirmed Chen Xin''s statement: "the food delivered in the town every week is only enough for one week. We can have this kind of food in stock only by the chickens in the greenhouse and chicken farm that you told us to build. They can get a lot of vegetables and eggs every month.


    In other villages, life is much more difficult than ours. They can only live on the food sent by the town every week. If the town does not send the food in time, they will starve, or even starve to death. "


    The second aunt''s words made Chen Xin feel palpitation and starve to death, which is already the memory of the previous generation in Yan state.


    Yanguo is a traditional farming civilization country. It has always been very dependent on the land to maintain the lives of the people. Even in the modern era with advanced science and technology, all kinds of natural and man-made disasters can still affect the farmers'' harvest and life to a great extent.


    In fact, before the large-scale promotion of hybrid rice in Yanguo, the grain yield of Yanguo has always been unable to meet the needs of the people, and the per capita cultivated area of Yanguo is also quite low in the world.


    This is also why, in the memory of the previous generation, the national famine was caused at the beginning of the war.


    If it wasn''t for yuan dadrui''s hybrid rice and the efforts of the majority of agricultural scientific research workers, Yanguo''s grain yield would have been able to achieve growth even though the cultivated land area was decreasing year by year, Yanguo would have faced the food crisis for a long time.


    In fact, it was only after entering the 21st century that Yanguo realized the transformation from not having enough to having enough.


    However, with the arrival of the doomsday disaster caused by the meteorite impact, the food crisis has actually come to the people of Yan country.


    The disaster caused by the meteorite impact is in all aspects, and the most direct impact is that the cultivated land of the whole country has been destroyed.


    Before the disaster, Yanguo''s national grain reserves were enough for the whole nation to eat for three years, but there was no output. Even if these grains can be eaten for ten years, they will be eaten up one day.


    Before the disaster, thanks to the efforts of the state, 80% of the population of Yanguo survived. These populations provided abundant labor for the post disaster reconstruction of Yanguo, but also brought enormous pressure on logistics, especially food supply.Before the disaster, Yanguo''s grain output has reached 650 million tons per year, and the per capita grain share is about 470 kg. So much food can meet the consumption of Yanguo people, which is why Yanguo people have changed from insufficient food to full food before the disaster.


    But now the 650 million tons of annual grain production has been completely turned into fly ash, and all the cultivated land in the country has been destroyed in the disaster caused by the meteorite impact. Limited by the current climate and environment, it can no longer be cultivated.


    At present, the main food source of Yanguo is the limited food produced by the greenhouses of various refuges and special planting areas, which can meet part of the needs and consumption, but absolutely can not meet the needs of nearly one billion survivors in the country.


    In short, if the country can''t solve the problem of food supply and demand before the grain reserves are consumed, a considerable number of survivors will starve to death in two to three years.


    For Chen Xin, he certainly can''t influence the whole country and let the people of the whole country have enough to eat, but he can still make his relatives at least have enough to eat in this apocalyptic disaster.


    As for the key to achieve this, naturally, it depends on the system to upgrade the refuge.


    However, upgrading can not be said to be a survival without any planning, which is easy to cause all kinds of problems. Even if we want to upgrade this refuge, Chen Xin must also consider the actual needs of his relatives.


    When Chen Xin finds his second uncle, he plans to ask him what are the current problems and what are the most urgent needs of this refuge in the village, and then consider the priority of upgrading.


    "What are the problems and needs of the village now?" After listening to Chen Xin''s question, the second uncle touched his chin and thought for a while, and then replied, "the question is nothing more than clothing, food, housing and transportation. Now we don''t need to go out on such a cold day. The only thing we need to consider when living in a shelter is heating.


    As for the rest of the food and clothing, it''s not a big problem. With the supplies sent by the town every week, plus the greenhouse in the shelter and the chickens raised by your second aunt, we can still guarantee that we will have enough to eat. "


    Chen Xin nodded and said summarily, "in other words, the most urgent need in the village is heating?"


    "It can be said that the weather is getting colder and colder. Everyone is doing things and activities during the day, but it''s hard to sleep at night." The second uncle showed his worry and said to Chen Xin helplessly, "now the shelter is heated by a generator, but the generator depends on a little gasoline sent by the town every month. If the next time the town doesn''t send enough gasoline or doesn''t send it at all, we won''t be able to survive."


    When Chen Xin finished listening, he immediately understood.


    Sure enough, even in different places, the demand is mostly the same.


    "Let me try to solve these problems for the village." Chen Xinchong''s second uncle made a promise, but also put forward some requirements: "I can help the village shelter do some transformation, but may need some materials, so please ask the second uncle you to ask for or change in the town."


    "Upgrading? Xin, can you really do it? What can that transform? " Second uncle heard Chen Xin say so, immediately showed concern.


    "There are many things that can be changed, but the first thing is to solve the problem of power supply. I first remove a battery from my car and connect it to the circuit of the shelter. In this way, the problem of power supply can be solved for the time being, and then I will carry out some transformation to make the power self-sufficient. " Chen Xin expounded his own ideas and explained them to his second uncle.


    After listening to Chen Xin''s idea, the second uncle showed a happy expression on his face, and the wrinkles on his forehead stretched out a lot: "if we can really solve the problem of power supply, it will be a great help! When the shelter was built, we listened to a Xin''s suggestion and installed a heating system, but unfortunately, the electricity has not been able to keep up, and now we dare not open that thing. "


    "Is there a heating system in the shelter?" Chen Xin can''t help picking eyebrows, but suddenly.


    Obviously, many problems were taken into consideration when the country built the shelter, and Chen Xin also reminded them of a lot of precautions about building the shelter at the beginning. There must be a solution to the problem of heating.


    It''s just that the shortage of energy makes the heating system a decoration.


    So first solve the problem of power supply, so that the heater can be turned on! Chen Xin made up his mind.

 Chapter 252

    In the power distribution room of the shelter, the second uncle and several elders stood at the door, looking forward to Chen Xin directing two young electricians to connect the isotope thermoelectric battery he removed from the car to the circuit of the shelter.


    "Well, just connect the red line and the blue line. With the power generation and service life of this battery, it can supply the whole shelter for more than ten years." Chen Xin watched two distant relatives connect the battery to the transformer of the power distribution box of the shelter with the circuit connecting cable, and then nodded to their second uncle for sure.


    "Can this really meet the electricity demand? Just a little bit of battery? " An elder obviously couldn''t believe it. After all, the isotope thermoelectric battery Chen Xin brought to us is too inconspicuous.


    It''s beyond the imagination of the elders who have been farming all their lives to supply such a large shelter with a thing as big as a hot water bottle.


    Chen Xin''s father was more receptive and asked Chen Xin, "what''s the output power of this battery? How high is the voltage? "


    "500V voltage, 150KW output power, this is for my car battery, to meet the needs of the shelter is no big problem." Facing his father''s question, Chen Xin answered seriously: "the voltage is a little high. You must connect the transformer to use it, and it is dangerous. You need to pay special attention when using it. But it''s not a big problem. After that, I will upgrade and optimize the circuit and adjust the access mode. There won''t be any problem. "


    Hearing Chen Xin say so, Chen Xin''s father calculated it, and then said to his second uncle: "the power is a little low, but it''s enough to meet the heating, that is, when other high-power electrical appliances are used, we should pay attention to the possibility of power shortage."


    "It''s good to turn on the heating, and there are other high-power appliances in the village." Second uncle heard Chen Xin''s father say so, immediately a pair of happy appearance, did not care about Chen Xin''s father said can''t open more high-power electrical problems.


    However, Chen Xin also heard his father''s words, thought about it and said, "this is not a problem. I made this battery by myself. I can change it with a car battery. If you go back to my second uncle and change two car batteries in town, I can change a battery pack. In this way, there will be no problem, and the production capacity of the greenhouse can be expanded by one Point out


    This is also what Chen Xin plans to do. Like his own refuge, he will increase greenhouse production capacity and obtain more output in exchange for more materials, forming a virtuous circle.


    "Can greenhouses increase capacity?" Second uncle is particularly concerned about this. As the head of the village for many years and a farmer who has cultivated land all his life, he is most sensitive to the output of crops.


    Chen Xin nodded his head and replied in the affirmative: "yes, after the electricity comes up, the fill light and heater in the greenhouse can work longer, so as to speed up the growth of crops and obtain higher yield. And I''m going to transform the structure of the greenhouse so that you can grow more food here. "


    Chen Xin''s words immediately made the elders present happy. For them, it is more practical than anything to be able to grow more food.


    "That''s a good feeling. It''s a good thing to grow more food! If you have grain in your hand, you will not panic. " The second uncle''s face was red with joy, which was quite different from the way Chen Xin had seen him for the first time when he came back.


    Chen Xin didn''t make any promises either. He just nodded and didn''t say much. He just had an idea about the transformation of the greenhouse. He had to see how to do it first.


    Now, second uncle, they can''t wait to turn on the heating in the shelter.


    With the heating on, the temperature in the shelter finally rose, and all the faces were smiling.


    Chen Xin also received the system prompt for a long time:


    "help others to improve their living conditions and get 5000 survival points"


    "help 4 people to improve their living conditions and get 50 survival points every day"


    of course, there are more than 50 people in the village, but only so many survival points can be gained by a single refuge to improve their living conditions.


    For Chen Xin now, these gains are gratifying, but they don''t make him pay special attention. What''s more important is that this way can bring him income.


    Thinking that he has provided isotope thermoelectric batteries to the state, Chen Xin can''t help but look forward to how much survival it will bring if the state promotes this technology.


    Even if a shelter has only 50 points, it is an astronomical amount of income under the large base of so many shelters in the country.


    Now the only thing that worries Chen Xin is whether the isotope thermoelectric battery produced by others under his own influence can be recognized by the system, thus bringing him the income of survival.


    Chen Xin is not sure about this problem, but the problem is not big. Even if the isotope thermoelectric battery produced by others is not recognized by the system, he can produce it himself and sell it to others.


    As long as the country starts to promote this kind of thing, it will inevitably become a hard currency. It will not worry about the sales volume. The impact on Chen Xin is nothing more than the survival of the final harvest.And as Chen Xin can provide more products, he will be able to harvest more survival. After all, although the harvest of survival can only be harvested once, there are too many places that can be improved in a refuge. He can cut one crop after another just like cutting leeks.


    The greenhouse of this shelter in the village is quite different from that of Chen Xin. Although it is also a greenhouse, the area here is obviously much larger.


    Moreover, Chen Xin can see that the greenhouse should have been transformed after adding a cover to the original farmland, instead of transporting the soil from the outside to the shelter as farmland.


    But even so, the area of cultivated land is limited. According to the second uncle''s introduction, the area of cultivated land here is only about one and a half mu, a total of 900 square meters.


    The 900 square meters of land is like a huge nine palace grid. In the center of the greenhouse, there are four thick supporting columns, and there are twelve similar supporting columns beside the wall to support the top span beam.


    Nine hundred square meters of farmland sounds like a lot of land, and the output is fairly good. But considering that there are more than 100 people in the village, the output is not much. After all, this greenhouse is not like Chen Xin''s, which can turn on lights and heaters 24 hours a day.


    The greenhouse with only one layer of soil is not like the multi-layer greenhouse upgraded by Chen Xin, which can realize three-dimensional planting and obtain greater yield.


    The crops planted in the field are also relatively single, with only cabbage, radish and a large area of leafy crops unknown to Chen Xin.


    "Second uncle, what kind of plant is this?" Chen Xin went to the edge of the leaf crop and looked at the vines and leaves growing almost close to the ground. He asked his second uncle curiously.


    "It''s sweet potato. It''s been planted for almost four months. It''s almost ready to harvest." Referring to these crops, the second uncle''s face was full of pride and satisfaction. As he said, he had grain in his hand, but he didn''t panic.


    For farmers in Yanguo, these crops with good harvest are the biggest source of happiness.


    When Chen Xin heard his second uncle say that this kind of sweet potato is sweet potato, he immediately showed a surprised expression: "is this sweet potato?"


    "Well? Ah Xin, haven''t you seen sweet potatoes? " Second uncle some doubts, sweet potato this kind of thing should be very common, Chen Xin should not have seen it.


    Chen Xin shook his head, reached out and touched the vines and leaves of these sweet potatoes, and said, "of course I''ve seen sweet potatoes, but I really haven''t seen the vines and leaves growing in the ground."


    Hearing Chen Xin say so, the second uncle nodded his head with understanding. It''s true that many people have eaten sweet potato, but not everyone knows sweet potato vine and sweet potato leaf.


    "Do you have a greenhouse yourself? Do you want to bring some sweet potatoes back? This kind of thing is very good. A sweet potato can be used as a seed after it is chopped up. " The second uncle thought that Chen Xin also had a greenhouse, and immediately proposed to him.


    Chen Xin heard the second uncle said so, but he didn''t refuse. He stood up and said, "I''ll trouble the second uncle. Although I have a lot of seeds, I really don''t have sweet potatoes."


    "It''s a small thing, but what kind of staple food do you grow there? You can''t just grow vegetables. It''s not enough to eat vegetables. " The second uncle is worried about Chen Xin. Obviously, in his opinion, the staple food should be planted in any way.


    Chen Xin didn''t have any questions about this. He replied with a smile: "I grow upland rice, which is more than enough for me to eat. In addition, there are many vegetables, so I can get a lot of food. After all, my place is a city, and the food is much better than my home. "


    When the second uncle heard Chen Xin say this, he nodded and asked him, "ah Xin, I''m relieved if you say that. Then you can see what can be transformed in this greenhouse. It''s good to increase the output more, so that the villagers can have enough to eat."


    This is also the second uncle''s most concern and expectation. Most of the greenhouses in front of him are planted with sweet potatoes, and the growth of sweet potatoes takes at least five to seven months. Even short-lived sweet potatoes take four months. Before harvest, the villagers can''t talk about how full they are.


    "I''ll have a look first. I just have an idea about how to transform it. I''ll see more about it." Chen Xin didn''t make sure, and asked his second uncle for his request: "second uncle, what do you think greenhouse should do? My idea is to add a hydroponic layer so that we can grow a lot of crops. "


    Hearing Chen Xin say so, second uncle can''t help but worry: "hydroponic cultivation? Is it easy to do? I''ve heard of this technology, but no one in the village has done it! "


    "This technology is not complicated. Second uncle, listen to me..." Chen Xin laughed and introduced hydroponic cultivation techniques to his second uncle.

    Although Chen Xin has transformed his own greenhouse from ordinary soil planting to hydroponics and soil planting at the same time, and added a comprehensive three-dimensional culture and planting system such as water fish culture, this experience is more suitable for small-scale greenhouses. For large-scale greenhouses, at least for the planting greenhouses in the village, the experience can not be applied mechanically .


    It''s also easy to understand that Chen Xin''s greenhouse is small and relatively simple to transform. Even if hydroponic cultivation and water aquaculture are added, it doesn''t need to add too much in terms of cost and investment. It only needs to add something to realize his idea.


    This is the so-called boat small good turn, but for a larger greenhouse, this is not easy to achieve.


    Not to mention anything else, the area of this greenhouse in the village is nine times that of Chen Xin''s original greenhouse. If hydroponic cultivation is carried out, the corresponding increase in investment and cost will be at least ten times, or even more.


    The increase of area is not only the accumulation of unit cost, but also other costs.


    For Chen Xin, or for the second uncle, these are things that must be carefully considered. We can''t make a decision directly.


    What''s more, we need to consider how to transform the greenhouse. If the area of the greenhouse is nine times larger, it''s not like Chen Xin''s greenhouse. Just build a shelf and put up the hydroponic planter.


    Water circulation in hydroponic tank, installation and circuit wiring of light supplement lamp, and installation mode of hydroponic planting tank There''s too much to think about.


    However, compared with many considerations about planting greenhouses, they can not be upgraded immediately. After Chen Xin solved the problem of electricity, the heating equipment in the shelter finally came into operation, which brought about immediate changes.


    Although the original shelter has a certain heat preservation effect, the temperature has always been very low. Even indoors, everyone has to wear thick cotton padded jacket to resist the cold. This is why the second aunt told Chen Xin that people''s life is not as good as that of chickens. After all, in order to ensure that chickens can lay eggs normally, they have heaters to heat, so people can only warm themselves by shaking.


    Fortunately, with the heater turned on, the temperature in the shelter increased significantly. At least everyone''s face, which had been gray due to the low temperature, was ruddy, so they didn''t look like they were whitewashed.


    Although low temperature does not directly lead to frostbite like severe cold for human body, long-term exposure to low temperature environment will still cause serious damage to human body, which is not only reflected in the pale complexion.


    Even from the damage to health, long-term low-temperature environment, human body damage is greater than frostbite.


    Although both of them can cause death in serious cases, one dies fast and the other dies slowly.


    In fact, for the vast majority of the survivors in the shelters today, hypothermia caused by low temperature is a problem they have to face. Lack of food, shortage of heating, and various factors, plus hypothermia is not as obvious as frostbite, it can be said that the number of people suffering from hypothermia is far higher than that of frostbite.


    Therefore, Chen Xin''s ability to make the heating equipment in the shelter work has a greater impact on the whole shelter than other things.


    In order to make sure that there are no other problems, Chen Xin and his father went to the machine room where the heater was installed to check the heating equipment. Naturally, Chen Xin also wanted to see what could be done to upgrade the heating equipment.


    "Cooling capacity 140kW? I don''t think the power of this central air conditioner is very high. " Chen Xin looked at the name plate on the device in front of him and was not satisfied with the output power.


    "It''s enough. This kind of central air conditioning is used in general hotels or office buildings. At most, there are several more in parallel." Chen Xin''s father didn''t care much about this, and even jokingly said to Chen Xin, "do you think that central air conditioning is like a circulating water cooling tower in a factory, with a flow of thousands of tons? Small devices don''t dissipate that much heat. "


    Chen Xin thinks about it for a moment, and it seems that this is true. After all, the relevant equipment he has been exposed to in his previous work are all large-scale equipment in the factory. The air-cooled cooling tower that takes circulating water as the cooling medium, even if it is a small cooling tower with only a few hundred tons of flow, its cooling capacity can reach several thousand kilowatts, which is really not comparable to this kind of small central air conditioning.


    "Do you want to revamp the equipment? Increase the output power? " Chen Xin asked his father, in his opinion, although the cooling capacity is not small, it is not satisfactory.


    It''s true that the temperature in the shelter is much higher than before, but the temperature has only risen from 0 ¡æ to a few ¡æ, which is not satisfactory. Chen Xin thinks that the output power can be increased a little bit.


    Chen Xin''s father hesitated for a moment and asked Chen Xin, "how do you want to change it? How much input, how much output power can be improved after the modification? How much more electricity will be consumed? "


    As a manager who used to be in charge of large state-owned chemical plant equipment, Chen Xin''s father has already formed a habit. When Chen Xin mentioned the transformation, he directly asked several key questions, and even almost wanted Chen Xin to produce a feasibility report.Chen Xin didn''t find it strange about his father''s professional habits for many years, but after thinking about it, he replied: "improve the operation efficiency of the equipment, increase the output power, and make the refrigeration capacity reach 200kW. The increase of power consumption should not exceed 30%."


    Of course, this is not the data that Chen Xin made up casually, but the conclusion that he came to by observing the external unit of the central air conditioner in front of him with the help of the upgrade interface of the system.


    When Chen Xin''s father heard that, he did not immediately agree. Instead, he continued to ask him, "it''s a way to increase the output power, but what''s the efficiency of converting the output power into cooling capacity? Compared with the original work efficiency, is it improved or reduced?


    You are only connected to a 150KW battery now. After the transformation, you have to consider whether it can meet the working needs of the equipment and whether the whole circuit can bear such a large load. You can''t just think about improving the efficiency of the equipment. "


    Chen Xin''s father has too much experience in this kind of equipment transformation. He clearly knows that the transformation of an equipment is not simply to improve the output power of the equipment.


    In his many years of work experience, he has encountered too many cases where the data on the surface looks very good, but the actual transformation can not achieve the desired effect, so he can''t help asking more about Chen Xin''s idea of transforming the heating equipment of the shelter.


    Of course, Chen Xin can understand his father''s worries and concerns. Although Chen Xin can solve these problems by relying on the system even if they arise, it is obviously more appropriate to consider the problems clearly before doing it than to solve them after an accident.


    So after listening to his father''s question, Chen Xin also rearranged his ideas, let the system upgrade interface show the new upgrade scheme, and then explained to his father in detail how he planned to reform.


    After listening to Chen Xin''s explanation, Chen Xin''s father thought about it and said, "you can change it like this, but I suggest you adjust the circuit first to ensure that the circuit can withstand such a heavy load, and then move the equipment to avoid problems."


    "I know, this is not urgent, and the transformation also needs materials. I have to ask my second uncle''s opinion, and he agrees to start the transformation." Chen Xin did not immediately accept the idea.


    Seeing that Chen Xin had already thought about it, his father didn''t say anything more. He just nodded to him: "just think about it."


    Of course, the shelter in the village can be transformed in more than three aspects: electric circuit, heating and greenhouse. However, after serious consideration and after asking his father and his second uncle for their opinions, Chen Xin decided to transform only these three aspects.


    Other places of the refuge can also be upgraded, but compared with these three aspects, the upgrading of other aspects is not urgent, and the improvement of the quality of life is not so obvious.


    Although for Chen Xin, as long as there is improvement and improvement in the quality of life, he will be able to gain survival, but in the second uncle''s opinion, it is not necessary to transform and upgrade where it is not necessary.


    The second uncle is in favor of the transformation of electric circuit, heating and greenhouse, but for other aspects of the transformation, because the improvement of the quality of life is not so obvious, in the second uncle''s view, it belongs to some waste and luxury.


    After all, Chen Xin didn''t use the method of directly smashing survival to upgrade. All of the transformation required his second uncle to exchange vegetables from the greenhouse in the town for the materials needed for upgrading. He obviously needed to consider the cost of the transformation.


    Chen Xin can also understand this, so he has no opinion about the second uncle''s plan to reform only three aspects.


    What''s more, Chen Xin''s original intention is to improve the quality of life for his relatives. For Chen Xin, helping relatives improve the quality of life and gain survival is just an expected extra gain.


    So in this matter, Chen Xin still fully respects their second uncle''s opinions. Since they have decided to only improve the electric circuit, heating and greenhouse, Chen Xin will not do much.


    After deciding to transform only the three aspects of electric circuit, heating and greenhouse, Chen Xin also made a list of the materials needed for the transformation and gave it to his second uncle, who also promised to go to the town as soon as possible to get the materials together.

 Chapter 254

    After working out the transformation plan with Chen Xin, the second uncle began to prepare the materials for the transformation.


    This is a big expense for the village. If it wasn''t for Chen Xin who proposed the transformation, and Chen Xin proved that he could improve the living conditions of the refuge through his actions, my second uncle might not be able to make up his mind to transform the refuge.


    Although there is a large greenhouse, a considerable part of the output of the greenhouse is used to exchange other food and various materials, and the rest is provided to the villagers. Therefore, the village is not rich. If we want to exchange materials for upgrading, we must reduce the expenditure on the other two aspects.


    This is not an easy decision to make in today''s world.


    Even if the second uncle is the head of the village, he needs to call a meeting to discuss and get everyone''s consent before making this decision.


    However, everyone in the village is very much looking forward to the improvement of living conditions. Although it will take a short time to live a tight life, the decision has been unanimously adopted, agreeing to exchange the vegetables to be harvested in the greenhouse this month for the materials to be used for upgrading.


    We will make such a decision. On the one hand, we hope for a better life. On the other hand, we trust Chen Xin.


    And this kind of trust of relatives also makes Chen Xin feel the pressure, although he will not live up to this trust.


    The second aunt''s father was responsible for the exchange of goods and materials. After he asked people to collect the mature vegetables in the greenhouse, he personally took these vegetables to the town.


    Chen Xin also came to the town with him, but in addition to dealing with the exchange of materials, he also needed to go to the hospital in the town to change the dressing for the wound on his head.


    Originally, Chen Xin could completely change his dressing in his car, but his mother still asked him to go to the hospital in the town to find a doctor to change his dressing.


    Chen Xin didn''t object to this kind of thing. Anyway, it''s just on the way.


    But when he came to the hospital in town, he couldn''t help regretting it.


    Without him, there are too many people in the hospital.


    The hospital in the town is expanded by the original town health center. After all, the original town health center can only provide basic medical services, and the number of patients that the design can accommodate is not high. After more than double the population in the town, the town health center obviously can not afford such a heavy load, and the expansion is a reasonable necessity.


    However, even after the expansion of the town health center, in the face of the medical and health needs of more than 50000 people, there is still a sense of unbearable burden, and even let Chen Xin feel that there are more people here than in the county hospital.


    After all, there are not enough doctors and too many people coming to see them.


    Compared with the majority of frostbite patients in the county hospital, the patients in the town hospital are more patients with hypothermia, which can be seen from the state of these people.


    This has no effect on Chen Xin. He just comes to change his dressing, not to see a doctor. Any little nurse can handle his affairs.


    With the help of a little nurse, she changes the medicine for the wound on her forehead. Chen Xin goes out of the treatment room and is about to leave the hospital to find her second uncle. However, she meets Zeng Liu in the corridor.


    "Mr. Chen Xin, how did you come to the hospital?" Zeng Liu said hello to her benefactor.


    Meeting Chen Xin in the hospital is also an accident and a surprise for Zeng Liu. After all, Zeng Liu is grateful for Chen Xin''s helping her.


    "Miss Zeng Liu, do you work here now?" Chen Xin didn''t find it strange to see Zeng Liu wearing a white coat.


    For this town hospital, which is already overburdened, it is good to have even one more medical staff, even though Zeng Liu is only a pharmacist.


    Zeng Liu nodded to this, and answered positively: "I have a pharmacist''s qualification certificate. The staff who was responsible for receiving US registered for us before. After that, Ning Jie and Tang were assigned to other shelters to continue to work as police officers, while I was assigned to the town hospital to continue to work as a pharmacist.


    Thank you very much. If it wasn''t for Mr. Chen Xin''s help to bring us out of that county, I''m afraid we might be dead now? There''s no reward for saving your life! "


    With that, Zeng Liu wanted to bow to Chen Xin to express his thanks.


    However, Chen Xin quickly stopped her and said, "it''s just a matter of lifting a finger, and you also helped me treat the fracture of my hand. It''s just an exchange of equal value."


    When Chen Xin said that, Zeng Liu had to put away her gratitude, but she was still grateful to Chen Xin.


    "Mr. Chen Xin, have you found your family?" Zeng Liu still remembers Chen Xin saying that he came here to find his parents, so he began to care about this problem.


    Chen Xin nodded, gave Zeng Liu a smile and said, "I''ve found my parents. I''ll go back to Hunan Province with them after I finish some work here."


    Hearing Chen Xin say so, Zeng Liu''s face couldn''t help showing an envious expression: "congratulations to Mr. Chen Xin. It''s really great to be able to reunite with his family in the current world!"Zeng Liu''s admiration is absolutely from her heart. After all, her family is no longer there. Seeing Chen Xin reunite with her family, she feels envious and sad.


    After all, who doesn''t want to be with their family?


    Perhaps it is aware of Zeng Liu''s emotions, Chen Xin and she talked a few more words, then left.


    Zeng Liu on the other side, watching Chen Xin leave, inevitably fell into a kind of confusion and hesitation. After all, before arriving in this town, Chen Xin promised her that if she didn''t meet other shelters, she could follow him to three towns on the return journey.


    Compared with this strange town with only three companions, Zeng Liu had some friends in the three towns where he had studied in University.


    However, this idea just appeared less than a moment, and was dismissed by Zeng Liu.


    Having accepted such a great favor from Chen Xin, she is embarrassed to ask for more.


    So he just shook his head and went back to work.


    As for Chen Xin who left the hospital, he went to find the second uncle who went to exchange materials according to the information that his second uncle told him before.


    However, when Chen Xin found their second uncle, they seemed to be in a bit of trouble.


    After communicating with his second uncle, Chen Xin realized what had happened to them.


    It''s not that someone embarrassed the second uncle, but that they didn''t exchange enough goods in the town.

 Chapter 255

    Of course, the materials that ordinary towns can provide can not be compared with the city where Chen Xin was originally located, and even compared with the county not far from here, they can only belong to the degree of material shortage.


    The town where Chen Xin is now living has been expanded with a large number of people, and because of the expansion, a large number of materials have been concentrated.


    "Ah Xin, we only got the car batteries and some building materials you want." With an expression of embarrassment on his face, Chen Xin''s second uncle explained to Chen Xin the dilemma they are facing: "there are no metal materials and cables needed to transform the heating system in the town. We have to go to the county to get them. As for the things needed to transform the greenhouse, even if the county may not have them, we have to go to Anqing city to have them. "


    "Ah? No material? " Chen Xin did not expect that he would face such a situation and seemed to be unprepared.


    Did you underestimate the material tension under the present eschatology? Or is it just that there is not enough material in the town?


    Chen Xin quickly gave up thinking about the reasons, because no matter what the reasons are, they are all problems that need to be solved. As for what causes these problems, we can think about it after the problems are solved.


    Now what Chen Xin has to face is how to complete his upgrade plan with limited materials.


    "Second uncle, you can exchange what you have first. As for the other materials you lack, let my cousin drive my car to the county tomorrow to see if you can exchange them." Chen Xin said to his second uncle, but he didn''t feel embarrassed because of the shortage of materials.


    There is a lack of materials for upgrading the greenhouse, which is not something that Chen Xin can do nothing about. The big deal is to build a workbench first, and then use the workbench to process raw materials.


    It is also acceptable for Chen Xin to spend more time in one process to gather the materials he needs.


    As for the lack of raw materials Although there is a shortage of materials in counties and towns, it is not enough to say that even raw materials are in short supply.


    Hearing Chen Xin say so, there is no good way for the immediate situation of the second uncle can only nod, a little helpless said: "also can only first like this."


    After exchanging materials, they returned to the shelter.


    "Ah Xin, there are no materials available now. What are you going to do? If there are no materials, can''t the transformation be done? " Back in the shelter, the second uncle, who was quite worried, took Chen Xin to discuss the upgrade with him.


    Chen Xin, who has already had an idea about this problem, doesn''t worry that things can''t go on. He just smiles at his second uncle and says, "it''s not a big problem. There are materials, there are ways to make materials, and there are ways to make materials without materials. Besides, it''s not that we don''t have any materials now. Let''s stick to the existing materials first. It''s really no good to get some raw materials back. I can process them myself. "


    "Can you make it yourself?" The second uncle obviously didn''t expect Chen Xin to have such ability, and this answer obviously exceeded his expectation.


    "Well, it''s just some simple rough machining. With raw materials and tools, it''s not a big problem." Chen Xin nodded, for the system, this is really not a big problem.


    In the worst case, he made a living out of nothing.


    The second uncle, who didn''t know that Chen Xin had this ability out of nothing, looked embarrassed and said to Chen Xin rather apologetically, "is this too much trouble for you, ah Xin? Otherwise, we should stick to the things with materials first, even if there are no materials. "


    Chen Xin can naturally understand the second uncle''s idea, but Chen Xin neither wants to explain, nor does he need to explain, let alone explain that materials are not necessities for him.


    So in the face of the second uncle said "no material even if the" such words, Chen Xin can only smile after saying: "first tight some materials to do it, as for the rest of the look back, cousin tomorrow to the county can get something more, right?"


    See Chen Xin all said so, two uncles also can promise Chen Xin''s words, first tight some material to get.


    However, he was very embarrassed to Chen Xin and said, "I''ll trouble you, ah Xin. I''m sorry to give you a busy schedule before and after the injury is over."


    "It''s all my own family, so I don''t have to say that. Besides, it''s just a small lift, and it''s not much trouble." Chen Xin just politely said goodbye to his second uncle and went back to his room.


    There is no entertainment in the shelter that can hold hands. Even the traditional entertainment such as playing cards and mahjong could not be carried out because of the low temperature before Chen Xin started to run the heating system. In fact, everyone in the shelter has long been used to having a rest early after dinner.


    After all, for them, they will wake up very early in the morning. In this case, it is a natural choice to go to bed early that night so that they can sleep more time in the day.


    However, for Chen Xin, he still has a lot to deal with.Because he didn''t expect that there would be a shortage of materials in advance, Chen Xin''s previous list of materials for upgrading his second uncle was based on parts, such as the radiator and compressor for upgrading the heating system, rather than the raw materials for manufacturing these materials.


    So now Chen Xin needs to adjust his demand list, adjust the material list according to the existing materials, adjust the materials of some parts into raw materials, and also add the materials of the workbench.


    Although the total amount of materials required is increased, the difficulty of obtaining materials is reduced.


    "OK, give this to my cousin tomorrow, and let him go to the county to see if he can gather enough materials." Compared with the system, after reorganizing the list of materials needed for the upgrade, Chen Xin couldn''t help taking a breath and rubbing his left wrist.


    Chen Xin is not left-handed, but when his right hand is injured, he can only write with his left hand. This undoubtedly makes Chen Xin, who usually doesn''t write with his left hand, feel particularly uncomfortable. At the same time, he wastes more efforts to write clearly.


    Fortunately, I finally wrote a list that people can see clearly. I just need to give it to my cousin who is responsible for changing materials in the county tomorrow.


    Put things away and Chen Xin is ready to go to bed.


    However, just when Chen Xin had finished washing his feet, poured himself a hot water bag and was ready to get into bed, his door was knocked.


    "Xin, are you in the room?" People outside the door asked.


    "What''s the matter? I''m going to sleep. " Chen Xin got up to open the door and saw a relative who was not very familiar with Chen Xin.


    "Ah? Xin, are you going to sleep? I want to have a chat with you The relatives outside seemed embarrassed, but they still tried to say something to Chen Xin: "can you have a simple chat? It won''t take you too long


    "Is there anything you can''t say tomorrow? I''m really going to bed Chen Xin couldn''t help frowning, but he was not happy.


    Although all the people in the village can be regarded as relatives, even the relatives are close and distant. At present, this relative is just a relative on the lips, not familiar with Chen Xin at all.


    Maybe Chen Xin''s parents know who he is, but they don''t even know the name of the other person or how to call him.


    This also makes Chen Xin not want to take care of him very much, just want to send people away as soon as possible, and then go to bed.


    It''s just that this man is stuck at the door and does not walk. Chen Xin is really disgusted.


    In particular, what makes Chen Xin feel bored is that this man has been chatting around at the door for a long time, but he doesn''t say what he has to do with himself. By beating around the Bush, Chen Xin doesn''t know what his intention is.


    If it''s normal, Chen Xin may deal with it and think about what the other party will do to find himself. But now he just wants to go to bed, which makes him lazy to analyze what this person is looking for himself for, and just wants to send people away.


    Just when Chen xinkuai was about to lose his temper, the second uncle appeared in time. After three or two words pulled the man away, Chen Xin was able to close the door and lay on the bed with a long breath.


    The warm bed comforts Chen Xin''s mood and makes him feel in the mood to think about what happened just now.


    In fact, it''s not hard to guess the purpose of the relative he doesn''t know very well. Although he has been beating around the Bush and refusing to speak directly just now, it''s not hard for Chen Xin to see that the other person''s purpose is to get along with him.


    But why do relatives suddenly come to have a relationship with themselves? I''m a relative I don''t know at all.


    This made Chen Xin confused and didn''t understand what was going on.


    For Chen Xin, the relatives in the village are not very familiar. Even for his second uncle, who are still familiar elders, Chen Xin only met once or twice with his parents every year when he went to visit relatives on New Year''s day. If it wasn''t for his parents'' relationship, Chen Xin might not be as familiar as some of his more familiar friends.


    People don''t treat a person well for no reason, so this unknown relative suddenly comes to try to have a relationship with him, especially when he is about to go to bed, obviously to avoid the sight of other people, which makes Chen Xin feel very confused.


    It''s not a shameful thing to have a relationship. Can''t we do it in the daytime? Why do you have to choose when you are going to sleep at night?


    Moreover, this kind of relationship is obviously not the main purpose of the relative. He must ask for something from himself, and then he needs to have a relationship because of the estrangement.


    So what does he want to do? Chen Xin''s mind reverberated with such questions, so he fell asleep.

 Chapter 256

    Chen Xin thought that it was only an example to find his relatives, but he did not expect that this was not an isolated incident.


    The next morning, Chen Xin came to his car and had breakfast with his parents. When he told them that he was going to let his brother-in-law drive his car to the county town to exchange materials, Chen Xin''s parents told him that not only relatives came to him last night, but also relatives came to them.


    Of course, Chen Xin''s parents are easier to deal with than him. After all, they have lived here for more than half a year. No matter how often they are unfamiliar with their relatives, they have been familiar with them for more than half a year.


    "So what do they want?" Chen Xin felt very puzzled, and then asked his parents.


    These relatives are neither close nor familiar with their families, and they even have five clothes. Chen Xin can''t help wondering what these people are doing.


    As for Chen Xin''s questions, his parents were more thorough than him. Chen Xin''s father said to Chen Xin with a smile, "have you ever heard a word, poor in the downtown, no one asks, rich in the mountains, distant relatives. These people are your mother''s distant relatives, not even your distant relatives, but you are living a good life now. Naturally, these people want to get some light from you. "


    "What''s the point? What kind of world is it now? I can take good care of myself. I''m already in charge of a few relatives and friends. I don''t care about distant relatives! " Chen Xin can''t help complaining.


    and Chen Xin can''t help but Tucao: "and even if there are distant relatives in the mountains, what can I make complaints about these distant relatives? I''ll go back to Hunan Province after I help my second uncle to upgrade their equipment. Do these people want to follow me back to Hunan? "


    However, speaking of this, Chen Xin suddenly noticed his parents look at him, some suddenly, but also some can''t believe it.


    He looked at his parents and asked, "do they have this idea? Are you crazy? "


    "Crazy? He''s smart! " Chen Xin''s mother took a bad look at Chen Xin. She didn''t explain much, and didn''t say anything good for her relatives who were all out of five clothes. It seemed that Chen Xin had to think and judge everything by herself.


    However, Chen Xin''s father still couldn''t figure it out, which reminded him: "do you think your life is bad now?"


    Hearing his father''s warning, Chen Xin immediately responded.


    Do you have a bad life? Of course not!


    If Chen Xindu said that he had a bad life, I''m afraid few people dare to say that he had a good life.


    There is no need to worry about food and drink in the private refuge, and there is a stable supply of goods and materials. As long as there is no disaster that completely destroys the world or changes the terrain, under his current conditions, even if he completely cuts off contact with the outside world and relies on his own refuge, Chen Xin can survive.


    Moreover, he has the ability to cross four provinces and run more than 600 kilometers to pick up his parents home, which is not what people struggling on the survival line can expect.


    In particular, after Chen Xin arrived at his hometown''s shelter, he took out the goods and other food. It''s a good thing to say that air dried meat is really scarce nowadays. I''m afraid that people who are not idle even want to smell it.


    However, Chen Xin was able to take out a box of dried meat and give it to others. It is obvious that he has abundant materials to do such a thing.


    This can not help but make Chen Xin a little annoyed that he is reckless, and only cares to bring some gifts to his relatives. As a result, he even forgets such things as not showing his wealth.


    Besides reflecting on this, Chen Xin is also thinking, do these people really have a bad life? So I want to follow myself to Hunan Province.


    However, after Chen Xin made a comparison, he found that compared with him, these people really had a bad life.


    Before Chen xinlai, we were able to live on, but we were short of supplies and heating. We didn''t live as well as we did. It was only slightly better than the situation of starving people in the nearby village shelters.


    As for the situation in the town and the county, it may not be so bad, but considering that there are so many people with hypothermia in the town and so many people with frostbite in the county, it is conceivable that their life is not very satisfactory.


    After a comparison, Chen Xin found that if he changed himself, he would make the same choice. He would live a better life with his relatives who obviously had a good life, instead of staying hungry and suffering from cold.


    This only needs to pull down a little bit of face to have a relationship with distant relatives who are not familiar with us at ordinary times. There is nothing more cost-effective than this.


    And whether Chen Xin is willing to take them or not is of course a matter of gambling for them, but it''s just a matter of face. If the gambling is successful, Chen Xin will not be able to take them with face. Even if it''s just to take them to the city where Chen Xin lives in Hunan Province, it''s better than to suffer cold in this mountain village, isn''t it?


    You should know that Chen Xin''s city is also a prefecture level city, which is four levels higher than the village, the lowest administrative unit in the country. In terms of material supply and living conditions, it is equivalent to Anqing City, the higher administrative unit in the county.For people in mountain villages, it''s better to go to the city to suffer from hunger and cold than to be in the village.


    Facing this situation, Chen Xin can only shake his head and feel helpless.


    In any case, these people can be regarded as relatives. Although they say five clothes, they can still be regarded as relatives. Although Chen Xin won''t really take them with him, there''s no need to shake their faces. After all, he doesn''t smile.


    And after all, Chen Xin did consider taking a few people back to increase the number of people in his refuge.


    His refuge now can accommodate at least ten people. If he and his parents are the only ones, there is a suspicion of waste.


    What''s more, if Chen Xin and his parents are the only three people in such a big shelter, many things will be too busy. Moreover, Chen Xin is fractured now, and even if he goes back, he will not be able to do heavy work for at least two or three months. His parents are also old, so they really need to consider the labor force.


    However, people always have distant relatives. Even if they really want to take people back, Chen Xin is also considering his serious relatives, rather than those who have five clothes.


    This is also a wake-up call for Chen Xin. Maybe he should talk about it with his second uncle? If there are really suitable relatives willing to go to their own place, Chen Xin feels that he is not unable to take them with him.


    As for what kind of people to take back, Chen Xin thinks it''s necessary to consider carefully. After all, the ability of the people to take back is secondary. The key is to be reliable in character. Otherwise, it will lead wolves into the house.

 Chapter 257

    He lent his car to his brother-in-law, who was in charge of driving, and to his relatives, who were going to the county to exchange goods and materials. Chen Xin then went back to the shelter and found his second uncle, ready to see what the materials he exchanged yesterday could do.


    The cables needed to transform the circuit were not replaced in the town yesterday, but the car batteries used to upgrade the power supply were obtained. With these, Chen Xin could first get out the isotope temperature difference batteries and put together a battery pack to supply power for the shelter.


    The second uncle knew Chen Xin''s arrangement today, took him to the warehouse, moved out the materials exchanged yesterday, and asked Chen Xin, "ah Xin, what can I do for you today? Would you like to get two men to fight for you? "


    Hearing his second uncle''s words, Chen Xin shook his head: "unless he is studying nuclear physics, he can''t help. Moreover, he has no physical work today. Just help me move things."


    Seeing Chen Xin say so, the second uncle didn''t insist, but after helping Chen Xin deliver two car batteries and some materials to his room, the second uncle called his nephew to help Chen Xin.


    Seeing his nephew called by his second uncle, Chen Xin, who should be calling his cousin, looks attentive. Chen Xin shakes his head. How can he not understand his second uncle''s meaning.


    "This cousin, you help to take things in first. I have something to say with my second uncle." Chen Xin explained to his cousin, took his second uncle to one side and asked him, "second uncle, do you have anything to tell me?"


    "Nothing..." Of course, the second uncle can understand Chen Xin''s purpose, but the second uncle, who can''t wipe off his face, still wants to play haha and put it off.


    However, Chen Xin shook his head and said to his second uncle, "the people who came to see me last night, and the people who went to see my parents Second uncle, you should know what they are going to do, right? Some things, even if I want to do, I must find reliable relatives. It''s definitely impossible for people who can''t make ends meet. "


    Because he was not sure what his second uncle meant, Chen Xin didn''t tell the purpose of those relatives directly, but Chen Xin put some things on the table. He believed that his second uncle should be able to understand him.


    Sure enough, the second uncle nodded to Chen Xin and said with a smile, "don''t worry, the people I recommend to you must be trustworthy relatives. They won''t do you any harm."


    Of course, Chen Xin has enough trust in his second uncle, but he is not sure about his trusted relatives.


    However, he is not good at directly refuting the second uncle''s face, so Chen Xin thought for a while and said: "the person you recommend must be trustworthy, but I still have to test the place to test. Whether a person is trustworthy or not, ability is one of them, but character is more important."


    "That''s right. You can try it. If you have any problems, come to me and I''ll solve them." The second uncle patted Chen Xin''s chest and made a promise.


    "I''m relieved to have your second uncle. If there are suitable people, you can let them come to me." Chen Xin is also very satisfied with the result, and the second uncle said two words, this just returned to the room.


    For Chen Xin, there is nothing worth describing about upgrading an ordinary car battery to an isotope thermoelectric battery.


    But for those who have never seen this scene, it is still beyond the scope of normal people''s understanding.


    After experiencing the recording of his upgrading process by those scientific researchers in Sanzhen, Chen Xin also thought about how this process was going on. However, the only thing Chen Xin could associate with was the nameless horror in the myth of kesulu.


    Because what we see and record is beyond the scope of ordinary people''s understanding, we can''t understand and analyze it. Even if we see and hear it, what we get is meaningless or distorted information.


    However, for those who have accumulated enough knowledge or are interested in exploring, they can obtain fragments of original information from meaningless and distorted information, and understand such a small amount of things.


    Although compared with the true information contained in the original, this scale and half claw thing is just a drop in the bucket, but it is the scope that ordinary people can analyze and understand, although this scale and half claw thing is likely to drive people crazy.


    Perhaps this is why in the myth of ksuru, those who pursue and explore the existence of the indescribable are crazy. They are not crazy, they just accept too much knowledge that ordinary people can''t understand.


    Of course, Chen Xin''s system may only have the same level of information as the indescribable existence. It does not mean that the system is an indescribable existence, or that the system also has the ability to distort and corrode everything.


    However, Chen Xin himself is not sure about this, because the concept of information state is vague. In a sense, the system''s ability to cover up and confuse is also a kind of distortion and erosion. Even compared with the nameless terror, what erodes and distorts is only the external form of matter, and the ability to distort and change the internal concept and essence of matter is more terrifying It''s a lot more.The so-called concept of fuzzy, this is a need for a little imagination, or even brain hole to understand the concept.


    For example, if we assume that the world we live in now is a virtual network world, everything is composed of data and information, and everything has its own attributes, then the concept of information state of the system is vague, that is, to modify the data of the object directly from the background, so that its attributes change, and all other people who see it will not be affected by the number It''s strange because of the changes in the structure and attributes.


    This is very terrible and terrible. To put it simply, this is a hacker who can tamper with the world''s data at will. In the eyes of the system, the whole real world is just a virtual game that can modify the data at will.


    But now the hacker''s ability is limited and restricted. What Chen Xin has mastered is the authority to control the hacker''s ability, and the survival point is the resources or energy needed to use this ability.


    The restrictions Chen Xin needs to use the system functions are just some irrelevant rules to avoid Chen Xin playing the game directly.


    No wonder in the original explanation of this system, it will be an entertainment system. For the higher civilization that can produce it, a material world, planet or civilization on the verge of destruction, maybe it can only be said to be a game?


    After all, to be able to turn this ability into an entertainment project, for this higher civilization, looking back on the destroyed world, planet and civilization is just a matter of reading a file, just like a game.


    As for why the system appears in front of him, and whether there is any conspiracy behind it, Chen Xincai is too lazy to think about it, because thinking is meaningless.


    Is it necessary for the advanced civilization that can make such a level of things to make any conspiracy to invade the world like Bluestar?


    Directly modify the "data" of a sweeper robot, and transform the household sweeper robot into emperor Titan, rampage first, GATA emperor, and demon Z Destroying the earth is nothing more than changing two more data.


    No one really thinks that the higher civilization of manufacturing this system needs to spend survival to "upgrade" a certain item, right?


    Even if they want to use Chen Xin to do something, can Chen Xin guarantee that his memory is not passive? It''s not very difficult to modify memory. In a sense, humans on the blue star can do it by themselves.


    So thinking about whether there is a conspiracy behind this is purely to find trouble and trouble for yourself. After all, even if there is a conspiracy, it is not something that Chen Xin, an ordinary person, can change and stop.


    Instead of asking for trouble, it''s better to make good use of the functions of the system to improve life for yourself and your family, so that you can better live in this end of life.


    In the town hospital, Zeng Liu finished his day''s work and said hello to his colleagues. After the handover, he left the pharmacy and went to the dormitory.


    After Chen Xin sent him to this small town, Zeng Liu was naturally assigned to work in the pharmacy because he had the qualification of a pharmacist.


    Although other medical departments need more manpower, it is difficult to find pharmacists with professional qualification in the town. In addition, the population of the town is soaring. Although the migrated population is also a complete town and has brought the manpower of a town health center, pharmacists are still insufficient and pharmacies are often too busy.


    Zeng Liu''s arrival can be said to be quite timely, so that the pharmacy can finally evolve from two shifts to three shifts, and the working hours of each pharmacist are reduced from 12 hours to the normal 8 hours.


    The town hospital is also a complete shelter, and the dormitory is naturally within the scope of the shelter. However, when Zeng Liu returned to the dormitory area, he found that old Tang and sister Ning were waiting for her at the door of her room.


    "Zeng Liu, can we have a chat?" Seeing Zeng Liu coming back, Ning said hello to her and then told her why she and Lao Tang came to find her.


    "Sure, sister Ning. What do you want to talk about?" Looking at sister Ning and old Tang, Zeng Liu happily welcomed them into his room: "come on, this is the dormitory assigned to pharmacists. My roommate just changed shifts with me, and now I''m the only one."


    Ning Jie and Tang are brought into their room. Zeng Liu pours a glass of water for them. Then he sits down and looks at them. He wants to know what they are looking for.


    "Zeng Liu, do you have any contact with Mr. Chen Xin who sent us here?" Sister Ning asked Zeng Liu about the purpose of her and old Tang.


    "Mr. Chen Xin? Are you looking for him? " Zeng Liu doesn''t know why she looks at sister Ning.

 Chapter 258

    People want to live a good life, which no matter who can not avoid.


    If someone deliberately pursues hard life, he either has ambition to sharpen his will, or has firm belief to purify his mind through pain.


    Apart from these two kinds of people, what other ordinary people want and yearn for is still a better life.


    Before Chen Xin returned to the village, although the life of the people in the village was better than that of the surrounding villages, it was also very limited and could not be regarded as very good.


    After Chen Xin came back, the life of the villagers has obviously improved.


    The restoration of heating, which is the biggest change affecting the shelter where the village is located, is just the beginning.


    The news that Chen Xin plans to upgrade the heating equipment and expand the greenhouse is not secret. His second uncle did not hide it from the villagers. Affected by this information, the villagers can naturally think that Chen Xin can bring them a better life.


    If that''s all, the villagers will not rush to Chen Xin.


    But Chen Xin only came back to pick up his parents. He is still in the village because he still has some affection for his relatives in the village and wants to do something for them.


    When Chen Xin finished these things, he still wanted to leave.


    What ordinary villagers think of is that Chen Xin''s appearance makes their life better than before. However, for people with more active mind, they can naturally associate with the equation of "Chen Xin = good life" and understand that they can live a better life with Chen Xin.


    This is not a difficult problem to think of or figure out. Although most of the people in the village are farmers, only a small part of them have gone out to work, it only means that they have less knowledge, but it does not mean that they are stupid.


    After figuring out that they can have a good life with Chen Xin, the first people who are shameless have already found Chen Xin or his parents last night, and the people who are close to Chen Xin''s family have also started to find their second uncle, who is the village head. All parties have begun to show their magic power and start their own actions.


    As for the villagers who are a little slower, less likely to lose face, and not particularly close to Chen Xin''s family, although they also want to have a good life through Chen Xin, they can do much less.


    It''s just that some people think that they are good at it, so they come to Chen Xin and hope to lead him to a "good life".


    Looking at the young man in front of him, who was wearing glasses, a suit and obviously dressed up, Chen Xin looked a little strange, but he still touched his chin and asked him, "do you want me to take you with me when I leave? It''s not a problem, but give me a reason to bring you. "


    It''s a long time since he resigned and became a full-time Internet writer, Chen Xin has not faced such a scene similar to an interview or recruitment, although he has participated in several interviews and presided over two recruitment.


    But now this kind of situation can be regarded as a kind of recruitment, only Chen Xin recruited not company employees, but members of his own team.


    This is also an inspiration to Chen Xin. In this end of life, he really needs to form a team. No matter in games or movies, the protagonists usually have teams or companions. In fact, there are few cases of fighting alone.


    It''s just like a team with a complete set of combat methods and nomadic occupations in online games. In the end, a team with its own strong points must have a better survival ability than a single person in the face of various crises and problems.


    What kind of companions do you need?


    While thinking about this problem, Chen Xin looked at the guy who obviously took the matter of looking for himself as an interview and listened to his self introduction.


    "I graduated from a 985 famous school in China and majored in finance. Before I worked in an investment company in the provincial capital, I had experience with it before..." The guy in front of Chen Xin seems to take it as an interview, and naturally recite his resume. But when it comes to his work experience, Chen Xin interrupts him directly.


    In the face of this man''s confusion, Chen Xin shook his hand directly and said to him, "now it''s the end of the world. It doesn''t matter what you''ve done before. Let''s talk about what you can do."


    "I am good at financial analysis, market investment, stock market forecast..." The young man spoke again, explaining his usually proud professional skills, but he was interrupted again by Chen Xin.


    Facing each other''s extremely confused and puzzled eyes, Chen Xin asked him helplessly: "in addition to the financial industry, which has no Mao month''s Dragon slaughtering skills, will you order anything else?"


    "Why is the financial industry useless! This is clearly the ultimate solution to all contradictions! " The young man was obviously very angry that Chen Xin''s evaluation of his ability was useless. He retorted very discontentedly.


    However, after hearing what he said, Chen Xin began to laugh, even with a stomachache: "is finance the ultimate solution to all contradictions? Ha ha ha, indeed, let the so-called financiers plunder everything and destroy everything through financial investment, which really solves all contradictions. ""Why do you say that? Financial investment clearly brings the necessary funds for the vitality and development of entrepreneurs and industries who lack funds through financing! " This young man is quite young and full of vigor. Although he came to curry favor with Chen Xin and hope to take him when Chen Xin can go, he now argues with Chen Xin.


    Facing the young people''s refutation, Chen Xin just said to him flatly: "finance itself does not create any wealth and value. It is only the economic behavior of the market main body to transfer funds from the surplus side to the scarce side through various financial instruments. This itself is no problem, and it is indeed a normal economic behavior to promote social development.


    However, financiers take advantage of this kind of economic behavior and turn the original normal monetary financing into a kind of plunder and destruction. No matter how the financial circles and financial experts beautify this kind of behavior, they still can''t cover up the evil behavior of bankers and investors plundering with the help of financial economic behavior. "


    Chen Xin seemed to be looking at the young man''s unconvinced appearance, then continued with a smile: "you just said that financial investment has brought vitality and development to entrepreneurs and industries who lack funds, which I don''t deny.


    But how many entrepreneurs have been kicked out of their own companies because of this so-called financial investment? How many industries have gone from the sunrise industry with bright prospects to the sunset industry without people''s attention because of the craziness of capital


    "But, but..." Young people want to refute Chen Xin''s words, but they can''t deny these facts.


    "If none of these can convince you, let me give another example. The famous Asian economic crisis in the 1990s was caused by the speculation of Siam''s currency by the federal financial investors at the beginning." As an Internet writer, Chen Xin has also checked quite a lot of information about the financial crisis in that year. Although there are many factors affecting it, the speculation on Siam''s currency is only the cause of the financial crisis, but it does not prevent him from taking this as a case to convince the young people in front of him.


    Chen Xin''s words certainly made the young man speechless. The financier who was in charge of the attack on Siam''s currency was revered as a God by the international financial community. This is his most successful and brilliant case. Even many finance textbooks will repeat it.


    Of course, young people have studied this financial case, and they are even familiar with the consequences of this case.


    Because of the Asian financial crisis caused by that financier''s speculation on Siam''s currency, in the next 20 years, the whole Asian region was depressed and stagnated from rapid economic development.


    The four little dragons of Asian economy, which had been recorded in textbooks at the beginning, almost fell into stagnation in the next 20 years. Only Yanguo avoided the impact of the financial crisis because it blocked the relationship with the financier at the beginning.


    "But don''t you see any good in finance? Financial investment is also permitted by the national policy, and finance is also a serious course in universities! " Young people obviously don''t want to be denied the degree they have studied hard for many years and the achievements they have worked hard for in recent years. They try to argue with Chen Xin.


    Chen Xin just shook his head and said without comment: "financial behavior itself is not wrong. Even if it is well used, it can greatly promote economic development and social progress, but uncontrolled and uncontrolled financial behavior will only bring damage and disaster to society.


    And to be honest, I don''t think financial behavior can play a big role in this end of the century. The state has been carrying out comprehensive material control, and all the means of production are in the hands of the state. Money in the market is almost equivalent to waste paper. In this case, it is all kinds of real industries that are really useful.


    I really don''t think the financial industry, which is totally dependent on the monetary system and does not produce any value, will play any role in this end of life and in the coming decades.


    So if you don''t have other skills and can only do this, then I can only say sorry to you. You have no effect on me because I don''t have the money to invest. "


    Hearing what Chen Xin said, the young man suddenly became very depressed, but he didn''t leave. After thinking about it, he asked Chen Xin, "I''ve been working in a financial investment company for several years, and I''m good at receiving customers. I''m good at receiving people and things. Is this useful to you?"


    "That''s OK. If I can''t find any staff, or if there''s a vacancy in the car, I''ll take one of you with me." Chen Xin thought for a while, but decided not to refuse directly.

 Chapter 259

    There is more than one relative who comes to find Chen Xin, and he has various abilities.


    In addition to the young man who studied finance at the beginning, some of Chen Xin''s other relatives came to see him. Some of them knew clay bricklayers and used to work in the construction team. Some of them were just farmers in the village and only knew how to farm. Some of them had worked as electricians and knew some electric power technology


    Chen Xin was a little annoyed by the appearance of various people, but he also saw the skills of these relatives.


    It has to be said that there are all kinds of people in the village, and there is even a Taoist priest who usually practices funeral rituals for all villages and townships, which makes Chen Xin feel fresh and fresh. At the same time, he can''t help laughing and crying.


    Some of these people are naturally very useful talents for Chen Xin. Even the farmers who only know how to cultivate land can be very useful in today''s end.


    Even Chen Xin, who studied finance before, felt that he could be thrown into the black market where Li Yulong was going to open up to become a salesman, so that he could make the best use of things and talents.


    But some people really let Chen Xin not know what he can do. For example, the profession of Taoist priest was in great demand in the rural areas in the past. When the older generation left, they needed someone to brag and chant scriptures. But now, in the end of the world, when people die, they just need to burn them. Who has the spare thought to hold funerals?


    However, even so, Chen Xin made a piece of paper seriously and recorded the situation of finding his relatives in the future. He planned to seriously discuss with his parents and then decide whether to take some of them back.


    While Chen Xin is busy dealing with his relatives, his cousin and second uncle finally get the materials he needs in the county with Chen Xin''s reorganized list.


    "Well, with these materials, the relevant transformation can be carried out." At the gate of the warehouse of the shelter, Chen Xin nods his head and says happily to his second uncle, looking at the second uncle''s request to move the materials back into the warehouse.


    The second uncle is also very happy about this. As the village head, he has been under great pressure since the disaster. After all, the life and death of hundreds of people in the village are all on him.


    Now Chen Xin says that he can improve the life of the villagers, which makes him the head of the village feel relieved.


    "Ah Xin, when can you start the transformation?" This is the second uncle''s main concern.


    "Let''s start tomorrow. Let''s upgrade the circuit first. By the way, I''ll set up the workbench and process these raw materials. Then we can transform the greenhouse." Chen Xin explained his arrangement to his second uncle, and also said: "the transformation of the greenhouse will increase the power consumption, and the power consumption will also increase after the heating system is upgraded, so upgrade the circuit first, so as not to overload the circuit later."


    As for Chen Xin''s arrangement, the second uncle didn''t have any opinions, but nodded his head and agreed: "ah Xin, you can do what you think you should do. If you need me to do anything, just open your mouth. If there are not enough people in the village, just ask! Let him come to me if he has any opinion. "


    "Don''t worry, second uncle. I know what to do." Chen Xin saw that his second uncle supported him and nodded to show that there was no problem.


    With enough materials, the upgrading of the circuit will not be as troublesome as before, and the electrician will be needed to connect the battery to the circuit.


    Chen Xin just asked people to move his two isotope thermoelectric batteries to the power distribution room. At the same time, he took a bundle of cables from his brother-in-law, and then directly opened the system interface for upgrading.


    Three isotope thermoelectric batteries were connected to the circuit, but Chen Xin did not let the three batteries connect to the circuit at the same time for power supply.


    After all, the total power of the three isotope thermoelectric batteries is as high as 450KW. This is just a village level refuge, and it does not have such a high power consumption.


    Even if Chen Xin has upgraded the heating system and the greenhouse, plus the daily electricity consumption, two batteries are enough to meet the electricity demand, and three batteries only use one of them as a backup.


    Although there is a suspicion of waste, it''s not a big investment for Chen Xin, and maybe it''s because he always liked the plan of "two open and one standby" when he was working on a project, so he did it easily.


    After upgrading the circuit, Chen Xin naturally received feedback from the system:


    "help others to improve their living conditions and get 5000 survival points"


    "help others to improve their living conditions and get 50 survival points every day"


    looking at the prompt given by the system, Chen Xin nodded with satisfaction and estimated again if he would upgrade three projects How many survival points can be gained after all.


    Before departure, because of the overall upgrade of his refuge, Chen''s survival has been basically exhausted. He has been walking for nearly a month, and he can get more than 100 survival points every day, but he has accumulated more than 3000 survival points again.


    Previously, he helped the village''s shelters to restore heating, but now he has upgraded the circuit. Together, Chen Xin has gained 10000 points of survival and 100 points of survival every day.If the greenhouse and heating system can be upgraded in the future and the survival of the top grid can be harvested, then Chen Xin will get a total of 20000 survival points in the shelter in his hometown, and 200 more survival points will be added every day, which can be described as a very rich income.


    By this calculation, Chen Xin predicted that the survival stock would reach about 23000 points, and continue to increase at more than 300 points per day.


    This is more than the total harvest of Chen Xin who spent more than half a year reforming his refuge.


    This also makes Chen Xin deeply understand that there is no future for a man to be a sword God of Shilipo. To actively cooperate with others and help other shelters improve their living conditions is the right way to obtain survival on a large scale.


    If he had chosen to go directly to the official shelter to upgrade, perhaps his total survival now has exceeded six figures.


    After all, there are not many projects that can be upgraded in a shelter. The two projects of electricity and heating can''t be bypassed. Chen Xin can go up and down like this in every shelter. Seven or eight shelters can be wiped down. The survival of six figures should not be too good.


    However, with so many survival points, Chen Xin also has some new ideas on how to use them. Maybe some ideas and ideas that were originally abandoned because of the lack of survival points can be put on the agenda.


    With such an idea in mind, Chen Xin first set his eyes on his own car, but there are still many ideas that he didn''t apply to it. Now that he has enough survival, he may be able to afford luxury.

 Chapter 260

    After having a carpenter''s relative in the village make a workbench for him and spend hundreds of points to upgrade it, Chen Xin processes all the raw materials for upgrading the heating system and greenhouse into corresponding parts.


    With these parts, the upgrading of the heating system and the transformation of the greenhouse have been successfully completed, which has brought Chen Xin rich survival income.


    And after doing these things, Chen Xin is also ready to take his parents home.


    All of a sudden, many people who want to leave the poor valley through his relationship and want to live a good life are anxious. They come to him more and more frequently, hoping to be liked by Chen Xin and take him with them.


    In order to achieve this goal, these people not only volunteered to show their talents, but also used all kinds of devious ways and means.


    It''s a basic operation to get close to relatives, because the whole village can talk about relatives, and a considerable part of them are still in the Chen Xin family. If you really talk about relatives, you can only be close to the Chen Xin family.


    So some other means are expected, such as inviting Chen Xin to dinner and giving gifts.


    Although there are no good things in the shelter, after all, the village is nearby. Before they live in the shelter, the villagers still have enough time to hide or put away their valuable treasures.


    However, the antiques of prosperous times and the gold of troubled times were valuable things in the past peaceful times. Now, in this last era, there are few things that can really be valuable.


    After all, gold and silver jewelry can not be used to eat and drink, nor can they be put on to protect themselves from the cold. Even if they are sold on the black market, they are not worth a radish.


    For Chen Xin, the so-called valuable things brought out by these relatives really don''t exist in front of his eyes. On the one hand, he really doesn''t like them, and on the other hand, in order to avoid trouble, Chen Xin refuses them one by one.


    In order to avoid those annoying relatives, but also to make their own living more comfortable, Chen Xin simply moved back to his car.


    Of course, the conditions in the car are better than those in the shelter. His parents had already lived in the car a few days ago. Now Chen Xin can''t bear to move back.


    But after moving back, Chen Xin found it inconvenient.


    Although there were other people in the car, they were just strangers. It would be nice to borrow a place to sleep for these people. Chen Xin could sleep in the most comfortable bed in the car, and there was no inconvenient place.


    But his parents live in the car. No matter what, Chen Xin has to let out the most comfortable double bed at the back of the car. He either sleeps on the sofa or on the double bed on the roof of the car. But for Chen Xin, who has a broken hand, it''s either inconvenient to go up and down, or it''s not comfortable enough to sleep on the sofa.


    In addition, Chen Xin is already in her thirties, and there are some inconveniences in her life with her parents, which makes Chen Xin more determined to change the car again.


    After a night in the bed on the roof of the car, Chen Xin can''t afford to collect materials to save on living expenses. Anyway, there are more than 20000 living expenses now, and there are more than 300 income every day. He has enough confidence to directly smash the survival to upgrade his car.


    This time, Chen Xin didn''t go to the big structure of the EMU. Instead, he planned to upgrade the living cabin and adjust some functional areas of the car to make the car more comfortable and have more living space.


    So in Chen Xin''s idea, he doesn''t plan to move the front part of the car, but only plans to expand and heighten the rear living cabin.


    The expansion and heightening of the life cabin will inevitably affect a series of things, such as the track at the bottom, the power system, and the wiring inside the car. Fortunately, Chen Xin can completely hand over these things to the omnipotent system. He just needs to figure out how to transform himself.


    Now Chen Xin doesn''t plan to move the sofa area of the living cabin, but he wants to move the flow management platform which was originally in the middle of the living cabin forward and put it in the front of the living cabin to keep up with the sofa.


    The door, which was originally opened in the front of the life cabin, was moved back and placed in the middle of the car body, from facing the sofa to behind the side of the sofa.


    This kind of adjustment makes the space in the living cabin a little more compact. At the same time, it also makes space in the rear of the living cabin, leaving room for Chen Xin''s next transformation.


    According to Chen Xin''s idea, the living cabin is no longer an open double bed, but a few separate enclosed spaces based on the design of the space cabin bed.


    First of all, the original double bed in the back cabin will be reserved. After the adjustment, Chen Xin plans to make it into a double cabin with two people half lying inside, and equipped with a mirror, air conditioning, shelf, coat hook, a small cabinet and lighting.


    And because of the heightening, there is a cabin of the same size and design above the double cabin.


    In addition, Chen Xin also reserved a total of four single cabins with the same structural design and internal configuration, except that only one person can lie inside.Two of the single cabins are placed close to the door, against the bulkhead of the living cabin, opposite the toilet, and the bottom is connected with the double cabins.


    The other two single cabins are next to the double cabins, which means that Chen Xin has changed the space at the rear of the living cabin where the double bed used to sleep only two people into four cabins that can sleep six people.


    This kind of cabin is a kind of cabin bed design Chen Xin used for reference. However, compared with the so-called cabin made of wood and ABS material, the cabin Chen Xin added to his car is obviously more comfortable and advanced.


    The sofa that can sleep in the living cabin is still preserved. As for the double bed on the roof, Chen Xin has made a certain transformation.


    It is no longer the shape of a bed, but some semi reclining sofas upgrade it from the original double bed to a leisure area with the function of a bed, and bookshelves and cabinets are designed on the wall, adding a lot of life functions.


    In addition, there is no big adjustment to Chen Xin''s car body. It''s just that with the increase of vehicle load after the transformation, the power system has been enlarged year on year, and at the same time of enlarging the living cabin, the water tank placed in the living cabin has also been enlarged, so that it can hold more living water.


    After the final design, Chen Xin looked at the system. If the whole upgrade does not use materials and reduces the investment in survival, it will cost 12000 points.

 Chapter 261

    The new upgrade of the car has not brought any great changes, except that it makes the car more comfortable than before, that is, the car body has become larger and higher.


    For Chen Xin, the three improvements and upgrades of the village shelter have been completed, and his car has been upgraded again. He has been able to leave with his parents.


    So naturally, Chen Xin began to prepare to leave the village and return to Hunan Province.


    This is quite normal for Chen Xin and his parents, but it''s not good news for people in the village who want to rub against them and follow them to Hunan Province for a good life.


    These relatives are all anxious, want to use all kinds of methods to entangle Chen Xin, squeeze him back to Hunan Province car.


    In the face of this situation, even if Chen Xin wants to take people away, it is impossible to take all these people with him, not to mention that most of them are ordinary people who have little ability and help Chen Xin, and their relatives are not so good.


    "Ah Xin, are you ready to leave?" The second uncle finds Chen Xin, who is preparing to leave and stores water in the water tank of the car, and asks him.


    Chen Xinkan, who had been looking for his second uncle, and two young men who were standing behind him looking a little cramped, immediately understood what his second uncle meant.


    For the second uncle to bring people to find themselves, Chen Xin has no antipathy.


    He really needs to recruit some people to form his own team. If the people recommended by his second uncle are suitable, Chen Xin doesn''t mind taking them with him.


    Chen Xin still needs to investigate whether these two people are really suitable, so he asked his second uncle, "all the things that should be done have been done, and the preparations are almost finished. If there is no accident, I will take my parents back in the next two days. Second uncle, are you going to recommend these two people to me? "


    "Yes, these two are my nephew, the son of my sister''s family, who calls your second aunt aunt as well." The second uncle introduced the two young men behind him and explained their abilities to Chen Xin: "this is Han Ze. You''ve met him once before. You can call him Xiao Han or Xiao Ze. He used to work as an electrician in Anqing. He has an electrician''s certificate. His level is not wrong, and he is very honest.


    In addition, Han Ping is Ozawa''s elder brother. He used to be a soldier in the army. He is a driver in the army. His skills are also good. The two brothers are of the same character. They are honest and reliable people. They are also hardworking and down-to-earth. Ah Xin, you can rest assured. "


    "It''s very good to hear that from uncle two, but I still want to ask, do they really want to follow me to Hunan Province? What about their family? " When Chen Xin heard the second uncle say so, he didn''t have any other opinions, but to be on the safe side, he asked one more question.


    For this question, the second uncle just looked at the two brothers helplessly, and replied in a sad tone: "the two brothers were not lucky. When it snowed in their village, the shelter collapsed. There were more than 100 people in a village, and they ran out of more than 30 people. They had no place to go before they came to me.


    Now ah Xin, you have important people here, and I think of their two brothers. Don''t worry about them. They are honest people, and they won''t make trouble for you or have any bad thoughts.


    If you are not satisfied with what they do, you are free to fight and scold them. Even if you want to drive people away, you can''t seize such a good opportunity. Let them go and die on their own. "


    Second uncle''s words were a little heavy, but Chen Xin could tell that second uncle was afraid that he would not accept the two brothers.


    However, Chen Xin noticed that the two brothers didn''t refute or resent the second uncle''s words. They really seemed to be two honest people.


    Chen Xin thought about it and said to his second uncle, "if there are only two brothers, it''s no problem to leave them. But I''ll leave them and other people will find him. What are you going to do?"


    "What''s the matter? I know better than you about the situation of these people in the village. Most of them are incompetent. I can see the ability and character of these two brothers. I recommend them to you with a clear conscience. You don''t have to worry about other people''s opinions. I''ll deal with them!" The second uncle took out his dignity as the head of the village.


    It has to be said that the second uncle, who has been the head of the village for most of his life, still has enough prestige in the village. After hearing what he said, Chen Xin put down his worry about it and agreed to leave the two brothers.


    The second uncle saw that Chen Xin agreed to leave the two brothers, so he turned to leave directly, leaving only the two brothers and Chen Xin.


    Chen Xin looked at the two brothers and didn''t say anything. He just looked at the display on the car body and noticed the water storage in the water tank. He let the two brothers stand in the snow and watch.


    After the water tank on the car was full, I went to turn off the tap, put away the water pipe, and asked the two brothers to get on the car.


    After that, Chen Xin had a preliminary impression of the two brothers. Just now, he filled the water tank for a long time, and the two brothers didn''t complain. They just stood by and waited, and didn''t ask anything. They really looked very honest.After letting the two brothers get on the bus and pouring them a cup of hot water, Chen Xin said, "let''s introduce ourselves first. Although the second uncle has just said that, you two still talk about your own situation, so that I can have a better understanding of you."


    The two brothers looked at each other. After making eye contact, Han Ze, whom Chen Xin had met once, took the lead in saying, "my name is Han Ze. I''m 25 years old. Before that, I had been working in Anqing city. I worked as an electrician in a telecommunication company. I was mainly engaged in the power maintenance of communication base stations. I studied technical school and learned this knowledge. In addition, I knew a little about radio because of my personal hobby Some. "


    For Han Ze, Chen Xin didn''t ask too much because he had seen him once before. After listening to his self introduction, he nodded and looked at the other brother.


    "My name is Han Ping. I''m two years older than my brother. I''m my brother. I''m 27 years old. I didn''t go to college. I went to the army after I graduated from high school." Han Ping saw Chen Xin look at himself, also very directly began to introduce himself: "I became a soldier for four years, in the army is a car soldier, learn how to drive, no other specialty, not as good as my brother."


    After listening to the two brothers'' self introduction, Chen Xin didn''t feel that the two brothers were incompetent. After nodding slightly, he continued to ask Han Ping, "have you ever been a soldier, can you shoot?"


    This problem is beyond Han Ping''s expectation, but after four years in the army, it is impossible to say that he will not shoot, so he nodded and said that he will shoot.


    Chen Xinjian said so, but he didn''t say anything. He just got up and took out the pistol that Zhang Chengguang had left behind from the cabinet behind the life cabin, and handed it to Han Ping: "how many minutes will it take to open it and put it back together?"


    Han Ping was obviously surprised why Chen Xin had a gun, but he didn''t question anything about it. After thinking about it for a while, he replied: "the best result in the army is that the pistol is disassembled and then assembled in 19 seconds."


    "19 seconds? Try it. " Chen Xin says, took out the mobile phone that cannot make a phone call from the body, called out the timer, put on the desk.


    Seeing this, Han Ping picked up the pistol on the table and checked it. Then he put the pistol on the table again, indicating that he was ready.


    Chen Xin taps his finger on the phone and shouts, "let''s go!"


    Han Ping instantly picked up the pistol on the table, took the whole pistol apart a few times, turned it into a scattered table of parts, and then quickly assembled them together.


    When he inserted the magazine back into the gun and finished the whole assembly, Chen Xin knocked again on his mobile phone and looked at the time recorded above, which showed "21 seconds".


    While Han Ping was holding the gun, his expression seemed to be tangled, but he still asked Chen Xin, "Mr. Chen, where do you come from?"


    "I saved three astronauts before. This is their self-defense pistol. They gave it to me when they left." Chen Xin explained to Han Ping, reached out and took the pistol from his hand and put it on the table.


    He didn''t worry about Han Ping''s threat to himself. Since he dared to take out the gun, he naturally unloaded the bullet inside.


    As for saying that Han Ping wanted to threaten him by force, he still had another gun in his pocket, which had bullets.


    When Han Ping heard Chen Xin say this, he quickly accepted this explanation. After all, the gun Chen Xin took out is a standard pistol. Although he has retired from the army for several years, he is still familiar with the standard pistol. This kind of new gun, which has never been used and has almost no wear and tear in the barrel, can not be easily obtained.


    Chen Xin is quite satisfied with Han Ping''s attitude. At least he has a sense of responsibility.


    After all, Yanguo is no better than other countries. When you suddenly see a gun, it''s either the people of the country, or the criminals, or the ferocious one.


    Han Ping can ask questions, in this situation, his performance has been very good.


    After that, Chen Xin continued to ask the two brothers a few questions. After a careful understanding of the situation of the two brothers, he asked the two brothers to go back to pack up and prepare to move to the car.


    As for the arrangement for the two brothers, Chen Xin thinks that his brother Han Ping can act as a driver and his own bodyguard, which can be regarded as a force in the team he is about to build.


    His younger brother Han Ze, who knows electrician and radio, can exist as a technician. Later, he can be specially responsible for radio work and act as a communicator.


    In addition, the two brothers grew up in the countryside, and they are not unfamiliar with farming. The second uncle''s recommendation sent Chen Xin two very useful people, which made Chen Xin very satisfied.

 Chapter 262

    Chen Xin recruited two nephews of his second uncle. Naturally, it soon spread to the whole village.


    For this matter, relatives naturally dare not complain about Chen Xin, even if they do. After all, Chen Xin is their only hope to leave the mountain village, and no one can directly express their resentment to Chen Xin.


    But for the second uncle, these relatives have nothing to say.


    Obviously, everyone felt that the second uncle was using his power for personal gain. Because he was the village head and close to Chen Xin, he first sent his two nephews to Chen Xin.


    For a moment, the shelter was full of gossip about the second uncle, and it was rather ugly.


    For this kind of situation, the second uncle naturally had expected that since he made such a decision, he was also prepared to face the subsequent impact.


    As a village head for many years, the second uncle has long had experience in this kind of thing.


    Although all the villagers are relatives, they are far away from each other, and even relatives put their own interests first.


    When their own interests are damaged, don''t say bad gossip, even pointing at the nose is light.


    Second uncle had already experienced too many similar things when he was young. He also had experience in how to deal with these things. After all, after so many years as the village head, he didn''t rely on inducing people to give in and become a peacemaker.


    Some people pointed to their noses and scolded that they wanted to smash their pots with bricks. In those days, the second uncle was able to control these people, but now of course, he is not afraid of his hands and feet because of the mere gossip.


    So on the whole, although things have some ups and downs, they have no impact.


    Naturally, the second uncle suppressed the affairs in the village, which did not affect Chen Xin. After he had finished all the preparatory work, he was ready to go back.


    The original recruitment plan did not go on. Except for the two brothers recommended by the second uncle, Chen Xin did not add new staff.


    Originally, Chen Xin agreed to take the young man who studied finance with him when he left. Unfortunately, the young man had his parents and an aunt besides himself. He hoped Chen Xin would take them all.


    This is obviously beyond the scope of Chen Xin''s acceptance, so he can only be rejected.


    As for Han Ping and Han Ze, they don''t have such trouble. The two brothers have already explained their own situation in their previous communication with Chen Xin. Their father died when they were young, and their mother brought them up, and then taught them to study.


    That''s why Han Ping, the elder brother, went to work as a soldier instead of going to college, while Han Ze, the younger brother, went to technical school. It''s not that they didn''t go to college, but that the family can''t afford it.


    Even Han Ze''s ability to study in a technical school is the tuition that Han Ping saved for his younger brother after he became a soldier.


    Although the two brothers are not highly educated, they are both hardworking and hardworking. Han Ping is advanced every year in the army. If he didn''t worry about his mother''s presence, he would have made better progress in the army and would not have retired to work in agriculture in order to take care of his mother.


    Although Han Ze didn''t go home to take care of his mother like his brother, he has been working hard to make money in the city. All the money he earned was sent back to his brother to take care of his mother.


    It''s just a pity that the shelter where the two brothers were originally located collapsed. The two brothers were young and strong, but they escaped with their mother. However, their mother, because of old age and cold weather, didn''t insist on waiting for the rescue and died, leaving the two brothers to go to the second uncle.


    Some of the information was said by the two brothers themselves, while some was inquired by Chen Xin through his parents.


    In Chen Xin''s opinion, the two brothers are very filial and reliable. This is the main reason why he agreed to take them with him. The recommendation of his second uncle is just the reason why Chen Xin is willing to give them a chance.


    So in the end, although many people want to go with Chen Xin to Hunan Province, he is only going to take the two brothers.


    Let Han Ping do a check on the vehicle, confirm that all aspects are in good condition, all the preparatory work has been completed, Chen Xin is ready to leave.


    However, just when Chen Xin Let Han Ping get on the bus, got into the co driver''s seat, prepared to drive and set out, and planned to teach Han Ping how to operate the car, Han Ping saw a truck driving in front of the shelter.


    "Mr. Chen, it''s a vehicle to deliver supplies to the shelter." Han Ping saw that Chen Xin also noticed the truck, so he explained it to him.


    "It''s none of our business. Don''t worry about it. Now I''ll show you how to drive this car." Chen Xin just took a look at it, but he didn''t care about it any more. Instead, he began to teach Han Ping how to drive: "this car is started by voice, so you must first input your voice into the console and give you permission."


    Han Ping listened to Chen Xin''s explanation carefully and cooperated with him to input his voice into the console.


    However, Chen Xin didn''t take care of the delivery truck, but the people on and off the truck came straight this way and knocked on the door next to the cab.Chen Xin opened the window, looked down and found that Zeng Liu was knocking on the door.


    "Zeng Liu? Why are you here? " Chen Xin can''t help being curious and asks Zeng Liu.


    "I came with the delivery truck. I came to visit Mr. Chen Xin about some things." Zeng Liu explained to Chen Xin that seeing that the car had been started, he quickly asked, "Mr. Chen Xin, are you ready to leave?"


    "Yes, I''ve already received my parents. I''ve done almost everything here. But miss Zeng Liu, you said you came to me for something. What''s the matter?" For Zeng Liu suddenly something to find himself, Chen Xin some strange, do not understand what she is in the end.


    Zeng Liu bit her lip and felt a bit embarrassed. She did have something to do when she came to find Chen Xin. She was asked by old Tang and sister Ning. But now Chen Xin is ready to leave, which obviously disrupts her steps and makes her not know what to do to achieve her goal.


    However, Chen Xin''s inquiry gave Zeng Liu the last glimmer of hope. Although this woman looked ordinary, she was able to seize the opportunity at the critical moment, so she said to Chen Xin, "Mr. Chen Xin, can I go up and talk?"


    "Come up? Well... " Chen Xin pondered for a while, then nodded and said: "come up."


    With that, Chen Xin signaled Zeng Liu to get on the car from the door of the living cabin on the other side. At the same time, he closed the window and said to Han Ping: "Han Ping, you should familiarize yourself with the operation console and various equipment first. I''ve given you permission. You can let the intelligent system of the operation console teach you to familiarize yourself with various equipment first, and I''ll see the guests."


    "Yes, Mr. Chen." Han Ping nodded seriously.


    Leaving Han Ping in the cab to get familiar with the console, Chen Xin turns back to the life cabin. After seeing Zeng Liu coming up from the door, he closes the door and asks her to sit down on the sofa.


    "Miss Zeng Liu, why did you come to me all of a sudden? What''s the matter? " For Zeng Liu''s arrival, this is quite unexpected to Chen Xin, but he still politely asked Zeng Liu why she came to find herself.


    Zeng Liu bit his teeth and then said, "Mr. Chen Xin, don''t you know you are still short of hands?"


    "Hands?" Looking at Zeng Liu biting his teeth, Chen Xin felt his chin: "it''s not a lack of manpower, but it''s good to have more people. Do you want to go to me?"


    Chen Xin was not surprised that Zeng Liu wanted to join him, but he didn''t like it.


    At the beginning, he saved her life and brought her companions with him. Chen Xin felt that he had done his utmost. Although he helped her to treat her fracture at the beginning, it was only a deal after all. Chen Xin had already paid for them and brought them to the refuge in the town, giving them a new life.


    Now Zeng Liu is entangled again, which seems to be a bit entangled in Chen Xin''s mind, which makes him feel too much.


    After all, Chen Xin doesn''t owe Zeng Liu anything. If she thinks she can do something with her previous friendship, Chen Xin can only say that she is delusional.


    However, some things went beyond Chen Xin''s expectation. Zeng Liu shook his head after getting his reply and explained to him, "it''s not me. It''s elder Tang and Ning. They don''t quite adapt to the life here. They think that you can have a better life with Mr. Chen Xin, so they ask me to come to you. I hope you can take them with you when you return."


    After hearing Zeng Liu''s words, Chen Xin was surprised, but he didn''t say anything. He just continued to touch his chin and asked, "what about you? Do you want to follow me? "


    Chen Xin''s problem made Zeng Liu feel embarrassed for a while, but she shook her head and said frankly: "if I had this opportunity, I would like to live a better life, but Mr. Chen Xin, you have helped me a lot, helped me to get rid of the dead city, and sent us to this small town so that we can survive. This is a great favor. I shouldn''t ask for more "Yes."


    "But your two companions don''t seem to think so." Looking at Zeng Liu, Chen Xin is satisfied that she can have such a cognition. By contrast, it seems that her two companions are a little out of proportion.


    However, Chen Xin still did not say anything. After all, Zeng Liu''s answer was only one side of her story, and Chen Xin had no way to judge whether it was true or not.


    "Sister Ning and old Tang They just want to live a better life... " Zeng Liu wanted to explain it for them, but he didn''t know how to explain it. After all, this kind of behavior was really out of proportion and excessive.


    Just remembering how Ning Jie and Lao Tang took care of themselves before, and their sincere request for themselves, Zeng Liu said to Chen Xin, "Ning Jie and Lao Tang want to take Mr. Chen Xin''s car to three towns. They promise that if you can send them to three towns, they will pay for it."


    "Well, pay? It''s fair. " After hearing Zeng Liu''s words, Chen Xin nodded and said, "but I refuse."

 Chapter 263

    Chen Xin didn''t care about the four people he rescued from the abandoned city.


    From the perspective of recruiting partners for the team, among the four, elder Tang and Ning Jie are just ordinary grass-roots police officers. Their professional ability and quality are very ordinary. They can''t compare with Han Ping and Qin LAN.


    They don''t have any more professional talents, which leads to that in a team, if they are fighters, they are not strong enough, and as professionals, they don''t have irreplaceable professional knowledge.


    So for Chen Xin, he doesn''t want to recruit these two people, especially when he has helped these people once, and they try to get him to help them.


    On the contrary, Zeng Liu is more valuable to be recruited. After all, he is a qualified pharmacist and knows some other medical skills. For a team, he can be a doctor or a healer.


    On the one hand, Zeng Liu didn''t mean to join Chen Xin''s team. On the other hand, Chen Xin has a better choice.


    On the other side of Hunan Province, Mo Qingxin, Mo Qingyan''s sister, although she has not yet received her diploma, is also a medical student who has completed all the systematic knowledge, and is already a qualified doctor.


    Moreover, Chen Xin also knows a "doctor" who can set up a clinic independently. His professional ability is more trustworthy, and he can also have a small nurse. He can buy one and get one free, which is very cost-effective.


    If the game is used as a metaphor, Zeng Liu''s four people are just the blue sky and white clouds that can be seen in the card pool, which can be used without other choices. However, Chen Xin already has purple rare partners like Qin LAN and Mo Qingxin around him, so naturally he can''t see blue sky and white clouds.


    Of course, if Zeng and Liu can show their aptitude and ability equivalent to the Golden Legend, Chen Xin is not unable to treat them differently.


    But it''s a pity that so far, among the people Chen Xin has met, there are only three astronauts, Zhang Chengguang, who can be called the Golden Legend. In addition, other people have not reached the level that Chen Xin thinks they can be called the Golden Legend.


    Therefore, it is inevitable for Chen Xin to refuse Zeng Liu''s request.


    However, he still thought that maybe he could give Zeng Liu a chance, so he asked her, "they want to take my car to Sanzhen. What about Miss Zeng Liu? Do you want to go to three towns? "


    For this problem, Zeng Liu did not hide his true thoughts, nodded and said: "if you can go to three towns, it is certainly good, but Mr. Chen Xin, you have helped us once, and we have no reason to ask you to help us again. Even if you pay, Mr. Chen Xin, you are not a taxi driver. There is no need to promise such a thing, is there?


    And now I have my own job and start a new life. It would be irresponsible for me to leave like this. So if I want to go to three towns, I hope I can achieve this goal through my own efforts rather than asking for help from Mr. Chen Xin. "


    "Well, in that case, I can only wish you success." Chen Xin is very satisfied with Zeng Liu''s attitude, and gives a compliment, which dispels his idea of recruiting Zeng Liu.


    After all, people intend to live better through their own efforts, and Chen Xin has no reason to stop her from working hard for her future.


    After a few more polite remarks, Chen Xin sent Zeng Liu out of the car. Then he went back to the cab and said to Han Ping, who was studying the console: "OK, we can get ready to start. Watch how I do it."


    "Yes, Mr. Chen." Han Ping hastened to respond and was ready at the same time.


    "System, cruise speed, forward." Chen Xin gave the command through voice, while holding the steering wheel with one hand, controlling the direction of the vehicle, making the whole car move.


    When Chen Xin set foot on his way home, in a confidential Laboratory of Chuanzhong space launch center, a group of researchers in heavy protective clothing had disassembled the isotope thermoelectric battery provided by Chen Xin and placed it on the experimental platform.


    "The radiation index is quite high, which is much higher than that released by normal isotope decay. It seems that the output of the battery can be improved by accelerating the decay and releasing more radiation energy." A researcher with a Geiger counter in his hand, put it close to the disassembled battery, looked at the reading of the meter, and said seriously.


    Another researcher was studying the battery liner on the table. Shaking his head, he said: "not only does it increase the rate of isotope decay, but also the heat energy conversion efficiency of the battery itself is quite high. We have tested the efficiency of the liner to convert radiant heat into electric energy before, which is at least twice as high as the efficiency of similar products of the federal government It''s incredible


    In addition to the two researchers, other researchers are also evaluating the disassembled isotope thermoelectric battery in their respective fields of expertise. Although many tests have been done before, they have fully understood the superior performance of the battery, but it is obvious that the technology contained in the battery still shocked them.For those who don''t understand, it''s nothing more than a very powerful battery. Although it''s powerful, it doesn''t have any real sense, and it can''t really realize how powerful it is.


    But for researchers who are so knowledgeable, they can clearly feel how powerful such an isotope thermoelectric battery is, and how difficult it is for them to do the same thing.


    "The machining accuracy of these parts is too high! Even Lucia and the federal government could only make similar products in a few high-end laboratories before the disaster, but these parts were only hand-made by others. It''s incredible... " A researcher, holding a magnifying glass, carefully observed a part in his hand and marveled at the machining accuracy of the part.


    Among the researchers, the chief engineer of the space launch center is the first. The white haired old man is wearing a heavy protective suit. At this time, he is commenting with admiration: "the high-precision processing ability is really admirable, but it is not the key point. The most important thing in this isotope thermoelectric battery is technology! Technology of transforming ordinary automobile battery into high performance isotope thermoelectric battery


    The chief engineer stressed this point, looked around at a group of scientific researchers standing in front of the experimental platform, and said to them earnestly: "although this comrade Chen Xin said that he was a postnatal scholar syndrome, he didn''t know why he had such ability and knowledge, and he couldn''t answer why he could do it, we can''t use this as an excuse to give up research and exploration Rope!


    As researchers, what we have to do is to explore the unknown! Since you don''t understand it, go and understand it! Since you don''t understand, try to analyze it! We should try our best to analyze the technology contained in this battery!


    Even if we can''t reverse restore all the technologies contained above, we should at least make imitations to improve the performance of our products, reduce costs and popularize them as soon as possible!


    This is related to the reconstruction of the country after the disaster, whether human beings can survive the present disaster! Such a high-performance battery can bring, will be a new energy revolution! So comrades, we must do our best to overcome all difficulties to complete the reverse analysis of this battery! Do comrades have confidence? "


    "Yes!" All of the scientific research personnel in the face of the white haired old chief engineer, together with a strong promise.


    "Well, that''s the spirit! Let''s get to work The chief engineer nodded his head with satisfaction. With a single order, all the scientific researchers immediately began to work.


    After all, the old chief engineer was old and had little energy. Seeing that the work had started orderly, he left the laboratory.


    After taking off his heavy protective clothing, the old chief engineer went back to the office and sat on the sofa feeling tired. He could not help feeling that he was really old.


    But the old chief engineer just had a little rest, then he picked himself up and went back to his desk to work.


    For the general manager who is responsible for the overall affairs of the space launch center, although the subordinates have done as much as possible to reduce the burden of the elderly, the elderly still have a lot of work to complete every day.


    Especially in the end of life, the elderly need to do more.


    "Chief engineer, this is our draft plan for cooperation with Comrade Chen Xin. Please review it." The door of the old man''s office was knocked open, and a staff member submitted a plan to the old man''s desk.


    After completing the performance test of the isotope thermoelectric battery, the state attached great importance to it and directly set up a special team to be responsible for the cooperation with Chen Xin, and the staff in front of us were the members of this team.


    The chief engineer raised his head and looked at the staff standing in front of the desk. He didn''t immediately go to read the plan sent by the other party. He just nodded and said, "put it on. I''ll see it later."


    "Yes, chief engineer." The young staff nodded, ready to quit the old chief engineer''s office, but looking at the tired look on the old chief engineer''s face, he still couldn''t help advising the old chief engineer: "chief engineer, please take a rest, don''t be too tired."


    "Thank you for your concern, but the old man can hold on. It''s not time to rest." The chief engineer didn''t accept his old age. He just laughed and continued to work.


    When the staff saw this, they had no way to say anything more. For the whole space launch center, the old chief engineer was a god of the sea needle. There were too many things that needed to be controlled by his old people, and the staff could only persuade the old people to take care of themselves.

 Chapter 264

    In Chen Xin''s shelter, Mo Qingxin looks at her sister coming out of the room with a good meal. She worries and asks, "sister, does LAN still refuse to eat?"


    "Well, she still doesn''t want to eat." With a worried expression on her face, Mo Qingyan nods to her sister and brings the food back to the kitchen.


    In the face of this situation, Mo Qingxin can''t help but feel anxious and said to Mo Qingyan, "but if you don''t supplement nutrition, it''s not good for her wound healing! Now this kind of situation, LAN elder sister does not eat how to go! "


    "Ah, understand ah LAN. After all, such a thing happened." Mo Qingyan sighs, and she worries more about Qin LAN.


    When Mo Qingxin heard her sister say that, she could only lower her head with regret. She also sighed and said, "if only ah Xin were here, he would have a way to persuade ah LAN."


    "Yes, he''ll certainly have a way." Mo Qingyan also nodded and agreed with her sister''s words: "so we should take good care of ah LAN now. When ah Xin comes back, we can find a way to enlighten her and let her out of the shadow of this matter."


    "I know elder sister, but now elder sister LAN has been unwilling to eat, her body can''t stand it! We have to find a way to get her to eat! " As a doctor, Mo Qingxin knows that for the injured, timely supplement of nutrition can get better faster and maintain the consumption of body recovery.


    If you don''t eat, the body will consume more nutrients than usual, and people will soon be unable to bear it.


    "Think of other ways. Put the food here first. Later, Xiao Xin, you can heat them up, and then give her a try." Mo Qingyan has no better way at this time, so she can only let her sister try again.


    Mo Qingxin nodded and agreed: "give it to me, elder sister. You can also have a rest. You haven''t had a good rest taking care of elder sister LAN these days."


    "I''ll leave it to you. I''ll take a bath and have a rest." Mo Qingyan smiles at her sister wearily. Then she goes to the room, ready to take a bath and have a good rest.


    Looking at her sister''s tired appearance, Mo Qingxin can''t help sighing again. She can''t help thinking that if only Chen Xin were here, she hopes that he can come back soon.


    But in the room, Qin LAN is lying on the bed lifeless at this time, with a dead look. It''s as if she has completely lost her spirit, leaving only a body lying here.


    Obviously, it is only when we are hit hard and the whole people are in despair.


    As for the reason why Qin LAN became like this, we just need to turn our eyes to her right hand, because Qin LAN has lost her right hand at this time, and her whole arm has completely disappeared from her shoulder.


    This happened two weeks ago. Qin LAN encountered an accident when she was on a mission. At that time, in order to save people, she was crushed under the collapsed bricks and earth.


    Although she was rescued in time, her right hand had to be amputated because of the heavy injury.


    This kind of thing is not to mention a special police sniper, even for an ordinary person, but also an unbearable blow.


    For a special police sniper like Qin LAN, the loss of one hand means that she has lost everything she used to be. So far, she has been working hard on her dream and has worked hard and hard


    All this is lost as she changes from a healthy person to a disabled person who has lost one hand.


    She can no longer hold her beloved sniper gun, can no longer return to the battlefield and fight side by side with her comrades in arms, and can no longer embrace her beloved with both hands. Everything is impossible.


    All these make Qin Lan''s heart sad. Even after two weeks of treatment in the hospital, her other injuries are cured and she can be discharged from the hospital, but her hands can''t come back and her inner trauma can''t be recovered.


    If Chen Xin is here, there may be a way to comfort Qin LAN, but when Chen Xin is away, there are only two sisters, Mo Qingyan and Mo Qingxin, who really don''t know how to comfort her.


    All they can do is to take Qin LAN from the hospital and put her in Chen Xin''s place so that she can take care of her at any time.


    However, even with the care of Mo Qingyan and Mo Qingxin, Qin LAN is still emaciated with naked eyes. Her whole life is full of vitality and vitality, as if her life has completely lost hope.


    Of course, Qin LAN knows that she can''t do without food, but she has no appetite and idea at all.


    For her, the loss of her right hand has become disabled, it is better to die so happy.


    In fact, Qin LAN might have committed suicide if she hadn''t been stopped in time.


    After all, such a thing for a girl, it is too big a blow.


    In Qin Lan''s opinion, her future life is hopeless.


    If it is before the disaster, perhaps she can rely on the prosthesis to restore the basic ability of self-care, not to despair, but also to start a new life.


    But in the present eschatological environment, she lost a hand and became disabled. Even if she was attached with a prosthesis, she also lost her ability to work, and she completely became a useless person. Who would spend a lot of money to install a prosthesis for her, and then accept her as a waste who lost her ability to work?Chen Xin? He will certainly take her in, but Qin LAN doesn''t want to be a drag on Chen Xin.


    She can be sure that after Chen Xin knows that she has broken a hand, she will try her best to get a prosthesis for herself, so that she can recover as much as possible. If Qin Lan''s mind is a little bit worse, she will rely on Chen Xin. She believes that Chen Xin will not drive her away, but will take good care of her.


    But Qin LAN doesn''t want to be like this. She doesn''t want to become Chen Xin''s drag and burden. That kind of life is not what she wants. If she really does that, she will feel shameless and die happily.


    On the one hand, the care of Mo Qingyan and Mo Qingxin prevented her from ending herself.


    On the other hand, Qin Lan also has a last wish in her heart, that is to say goodbye to Chen Xindao.


    Even if she wants to end her life, Qin LAN still wants to see Chen Xin for the last time.


    "Sister LAN, may I come in?" Just as Qin LAN thinks about this, Mo Qingxin pushes the door and comes in, holding the food that Mo Qingyan had brought once before.


    Put the food on the bedside table, Mo Qingxin checked Qin Lan''s body, and then advised her: "sister LAN, have something to eat! If you go on like this, your body can''t stand it! Even if you really don''t want to live, don''t you want to see ah Xin again? How can you hold on to him like this? "


    ¡°¡­¡­¡± Mo Qingxin''s words touched Qin LAN, and her eyes finally moved.

 Chapter 265

    Chen Xin naturally knows nothing about what happened to Qin LAN. At the moment, he is still on his way home.


    "Mr. Chen, why do we go from three towns? If you go to Huanggang City, you can save a lot of time. " Han Ping studied the map in his hand, some of which didn''t quite understand Chen Xin''s choice.


    Although there are no other refuges and supply points on the way back from Anhui Province along Chen Xin''s road, so that the consumption of materials is a bit large and must be supplemented, Huanggang City, as an important city in Hubei Province, has refuges and supplies.


    So Han Ping didn''t quite understand why Chen Xin had to walk a long way around the three towns.


    To this, Chen Xin just answered: "when I come here, I have an appointment with people. When I go back, I will go to three towns."


    When he heard Chen Xin say so, Han Ping didn''t say much. He just expressed his doubts and didn''t want to interfere in Chen Xin''s decision.


    For Han Ping, he is Chen Xin''s driver. Asking questions is what he should do, but it is Chen Xin who makes the decision. Since Chen Xin has made the decision, he just needs to implement it.


    Unless Chen Xin''s decision is too bizarre, in Han Ping''s opinion, all he needs to do is implement it.


    Hand over the driving to Han Ping, Chen Xin turns around and goes to the rear living cabin, intending to have a rest.


    With the addition of Han Ping and Han Ze, the biggest advantage for Chen Xin is that he is much more relaxed. Most of the things can be done by these two brothers, and he just needs to give orders.


    Han Ping, the elder brother, is responsible for driving, while Han Ze, the younger brother, is responsible for acting as the co driver. At first, the two brothers are still a little unfamiliar with the car, but after they are familiar with the driving style of the car, they are already competent for their work, so that Chen Xin can rest assured to give them all the driving matters.


    Back in the living cabin, Chen Xin saw his father standing in front of the planting box, as if he wanted to water the vegetables inside. So he went to his father and asked, "Dad, what are you doing here? Where''s my mother? "


    "Your mother is resting on it." Chen Xin''s father pointed to the top of his finger, then looked at the planting box in front of him and asked Chen Xin, "do you need to water this vegetable every day?"


    "Well, it doesn''t need to be watered every day. It has its own irrigation function. It will drip irrigation according to the soil moisture and crop growth, so as to ensure that the water needed for crop growth will not be over watered at the same time." Chen Xin explained one sentence.


    Hearing Chen Xin say so, Chen Xin''s father couldn''t help showing a pair of exclamation expression: "now technology is really developed, even watering don''t have to do it yourself."


    "Yes, the development of science and technology is very fast." Chen Xin nodded in agreement, echoing his father''s words.


    Talking about this topic, Chen Xin''s father didn''t know what he thought of. He suddenly asked Chen Xin, "son, do you think human beings will perish?"


    "No Chen Xin gave the answer to his father''s question without even thinking about it.


    "But now there is no sunshine, and we can''t farm. It''s still so cold outside. How can human beings survive?" Chen Xin''s father obviously finds it difficult to accept Chen Xin''s answer, or to get convincing reasons from Chen Xin. He still asks Chen Xin.


    "The dust in the sky will disperse in a few years. Although the dust in the stratosphere may not fall down for hundreds or even thousands of years, the dust in the troposphere will almost fall down in ten or eight years, and the sun will shine on the earth again at that time." Chen Xin also asked Zhang Chengguang some related questions before. When his father asked, he naturally answered in the affirmative.


    Before landing on the blue star, Zhang Chengguang used the observation equipment of the space station to observe the blue star for more than half a year. According to their observation, the blue star was surrounded by a large amount of dust and debris formed by meteorite impact.


    The materials raised by the impact of meteorites are distributed in the whole atmosphere and the near earth orbit of blue stars. From the troposphere at the bottom of the atmosphere to the outer escape layer at the top, they are densely distributed. It is these dust and debris that shield the sky and prevent sunlight from reaching the ground.


    The debris with large volume and weight will first fall to the ground due to the influence of gravity, and burn up due to atmospheric friction.


    The rest of the dust will fall one after another according to its height in the atmosphere.


    The dust in the troposphere at the bottom of the atmosphere will be the first to fall, and the dust in this layer is also the most dense. When the dust in this layer settles, the surface will transform from a dark environment to a low light level, and the light intensity will gradually increase.


    Although the dust in the upper atmosphere will be difficult to fall because the upper atmosphere is mostly translational, the light will still return to the acceptable level within ten years.


    Chen Xin explained to his father about the sun, and then added: "the sun is not the most critical factor restricting human beings. In terms of the science and technology currently mastered by human beings, although ten years without sun will have a great impact on human civilization, many people will die because of lack of food and cold, but it is not enough to destroy human beings."Hearing Chen Xin say so, his father is obviously relieved. After the disaster, the hardship he faced is not hard, but the lack of hope and future is the most unbearable.


    Chen Xin obviously understood this, so he said to his father, "the country is now in the process of post disaster reconstruction. The towns below may not feel much, but big cities like the three towns are gradually recovering. Perhaps the present living conditions will be a little harder, but they will certainly be better in the future! "


    "You don''t have to comfort me. I suffer more than your generation. It''s not your turn to comfort me." Chen Xin''s father has some embarrassment on his face, but he still maintains his dignity as a father.


    While father and son were still talking about this topic, Han Ze suddenly ran over from the cockpit and said to Chen Xin, "Mr. Chen, come and have a look. We have received the signal from the three towns. It seems that they are testing some equipment."


    "Where''s the testing equipment in three towns? We''re a long way from three towns, right? You can get their signal now? " Chen Xin was shocked and went back to the cab with Han Ze.


    As for Chen Xin''s question, Han Ze quickly introduced the situation: "I was debugging the radio station just now to see if I could receive the signal. As a result, I received the communication from the three towns, but they didn''t send it to us. They should be doing some testing. They started a high-power signal source, but we were just in the signal coverage."


    Chen Xin nodded slightly. After understanding the situation, he directly sat in the co pilot''s seat and said to the console, "system, replay the signal just received."


    "Signal playing..." The system''s electronic audio starts, and a signal is replayed at the same time.


    ¡°¡­ Long Communications In the test, third Test... " The signal doesn''t seem very clear, but it can be heard clearly.


    Chen Xin listened to the intermittent signals played by the system and generally understood what was going on.


    As Han Ze said, this should be a test, and his car only received the signal when it was within the signal coverage.


    Chen Xin didn''t find it strange about this. There are so many scientific research institutions in the three towns, so it''s not strange to do communication testing.


    As for saying that your car is shrouded in the signal coverage, it''s not surprising. That is, the satellite signal can''t be received in this kind of environment, otherwise it''s strange that there is no signal.


    "People are doing communication tests, so let''s leave it alone." Chen Xin confirms what''s going on, so he doesn''t care any more. He says to Han Ze, and then stands up to leave the cab.


    However, at this time, the console received a new signal: "thanks On That Chen Xin The adjustment of students This set of The end of the equipment To achieve long distance I''ve heard from you


    Hearing this, the expression on Chen Xin''s face couldn''t help showing his interest. Is it still related to him?


    It seems to have something to do with the set of communication equipment that they adjusted when they visited Sanzhen last time. Are they testing their adjusted equipment now?


    Chen Xin just a little association, then thought of what is going on, so he reached out and picked up the intercom on the console, a little operation, his car''s signal is also connected to the other party''s communication channel, pressed the call button, said: "I seem to hear someone mention my name, it seems that the last time I adjusted the equipment effect is not bad!"


    "Mr. Chen Xin? Why are you on our channel? " The other party seemed very surprised that Chen Xin was able to access their communication channel, but soon responded: "Mr. Chen Xin, are you back from Anhui Province?"


    "Yes, I''m on my way back now. I should arrive in three towns in two days." Chen Xin answered the other party''s question and said, "are you testing the equipment? Then I won''t disturb your work. "


    "No, no, Mr. Chen Xin, if you can, we hope you can help us test the new equipment!" The other side obviously does not intend to let Chen Xin quit like this.


    Researchers who have seen how Chen Xin modulates the device instantaneously will not let go of Chen Xin''s powerful foreign aid. Moreover, Chen Xin is just outside Sanzhen now. It is also a very important test to test the signal stability of the device when the target is moving with his help. It can save them a lot of things to ask Chen Xin to help.


    "All right, how can I help you?" Chen Xin is not stingy. Anyway, it''s just a matter of lifting a finger. He is idle on the road.

 Chapter 266

    While marching towards the three towns and cooperating with researchers to test their communication equipment, Chen Xin''s journey is not so boring.


    However, although the work of testing communication equipment is important and complex, it is actually not troublesome. Chen Xin and Chen Xin just need to accept the information sent by the other party, and then give feedback.


    In short, let a person sit in the co driver''s seat, chat with each other and answer questions through the communication equipment on the car.


    Although it''s simple, it''s not so boring as that. After all, Chen Xin was too busy to do a lot of things. After Han Ping and Han Ze shared the two tasks of driving and investigation, there was nothing for Chen Xin to do in person.


    After all, even his mother takes care of cooking because she loves the beauty of his broken hand. Every day, Chen Xin wakes up, eats, and sleeps.


    After two days of such a happy life, Chen Xin''s car once again entered the scope of the three towns.


    Relying on the pass I got last time, I went all the way to the three towns. Before I drove into the urban area, I sent letters to scientific research institutions, inviting Chen Xin to "sit down" with them.


    Chen Xin did not refuse the invitation. According to his estimation, the state should have completed the evaluation and testing of the isotope thermoelectric battery he handed in. Naturally, it should have come up with a plan on how to cooperate with him.


    Now to go to scientific research institutions is to talk about how to cooperate.


    What''s more, Chen Xin had promised to see each other again when he passed the three towns, so he had no reason to refuse the invitation.


    But this time, Chen Xin''s car couldn''t cross the river tunnel. The upgraded RV couldn''t enter the tunnel because of its super width. He had to cross the river or the Yangtze River Bridge.


    In the face of this situation, Chen Xin hesitated for a moment, thought about it, or let Han Ping drive the car from the river.


    Although I''m worried about the firmness of the ice layer, the ice surface, which has been frozen in the low temperature of tens of degrees below zero, is a little safer than the Yangtze River Bridge, which has been damaged several times by the disaster. After all, Chen Xin didn''t go to the Yangtze River Bridge last time.


    The situation on the ice surface is better than Chen Xin expected. Although the ice surface is very slippery, it is not a problem for the crawler chassis. Moreover, the thickness and load-bearing capacity of the ice layer are stronger than Chen Xin expected, and there is no such situation as cracking.


    This enabled Chen Xin to pass the Yangtze River very smoothly, even in the place with the thinnest ice layer in the middle of the river, there was no problem.


    The only problem is that Chen Xin''s car is too wide and too high after upgrading, and there is no way to drive into the underground passage connecting the optical valley.


    But it''s not a big problem. You can''t walk underground and you can walk on the ground.


    After Han Ping drove the car to the door of the building where the scientific research institution was located, Chen Xin left his parents in the car and only took Han Ping to enter the scientific research institution from the original door of the scientific research institution on the ground.


    "Mr. Chen Xin, we have to wait! We''ve been looking forward to your return since the day you left! " Last time, a researcher who saw Chen Xin rubbing a nuclear battery with his bare hands rushed up and held Chen Xin''s hand, saying "welcome" to him.


    Facing the excessive enthusiasm of the researcher, although Chen Xin could understand each other''s attitude, he still felt very embarrassed and quickly pulled his hand out of each other''s hands: "sorry, I broke my arm, I can''t shake hands."


    The researcher was shocked and asked: "how did it hurt? Doesn''t it matter? Please rest assured that there are the best doctors in our three towns who can provide you with the best medical conditions. Mr. Chen Xin, your hand is a national treasure. You can''t have any accident! "


    With that, the researcher yelled at the other staff around him and asked them to contact the hospital and doctors.


    Watching these people start to get busy, Chen Xin feels a little funny, but also very moved.


    Although these people attach so much importance to themselves because they master the black technology endowed by the system, it also means that Chen Xin is more important than he expected.


    "No, no, that''s why I had a slight fracture when I was driving in an avalanche. I''ve seen a doctor and taken a film. It''s not in the way." Chen Xin didn''t want to go to the hospital again. He quickly refused the kindness of these researchers.


    After Chen Xin comforted and explained, these researchers put out the idea of looking for a doctor to see Chen Xin again.


    After some twists and turns, Chen Xin and several researchers sat down in a conference room and began to discuss Chen Xin''s cooperation with the state.


    "Mr. Chen Xin, before we talk about cooperation, we would like to know if there is any limitation on the scope of your acquired scholar syndrome?" A researcher asked Chen Xin a question they were most concerned about.


    Because Chen Xin''s improvement ability has scope limitation and no scope limitation, which are two completely different concepts.


    Limited in scope, limited to one or two or a few subjects, Chen Xin is still very important, but not as influential.This will affect the research progress of one or two disciplines at most and accelerate the development of some disciplines.


    Although it can ultimately affect the whole country, it will take a certain amount of time for this kind of influence to have an effect.


    This is similar to the fact that there are top academic leaders in one or two disciplines, but Chen Xin does not engage in research, he only produces results.


    However, if Chen Xin''s capabilities are not limited in scope, the significance will be quite different. It is an important factor that can rise to the level of influencing the whole strategic deployment of the country and change the power of the whole country in a short time.


    So just now that researcher said that Chen Xin''s hand is a national treasure, it''s really not too much. No matter whether Chen Xin''s ability is limited in scope or not, it''s not too much to use Guobao to describe such talents who can at least accelerate the rapid development of a certain discipline or industry.


    In fact, these researchers have regretted that Chen Xin was injured. If they had paid more attention to Chen Xin and asked Hubei Province to send someone to follow him when he left, or even Hubei Province to send someone to Anhui Province to pick up his parents, Chen Xin would not have been injured.


    In the eyes of these researchers, Chen Xin is really a treasure that can''t be bumped at all. It''s better to stay in a safe laboratory and give full play to his ability, rather than running around like this and breaking himself.


    As for the questions and attitudes of the researchers, Chen Xin rubbed his forehead and asked, "how about the scope? What if there''s no scope? "

 Chapter 267

    Of course, Chen Xin''s ability is not limited in scope. As long as he wants, everything can be upgraded.


    For the system, as long as there is survival and physical reference, then nothing is a problem, there is no limit.


    Even as long as Chen Xin has enough survival, he can take the whole Yan Kingdom and even the whole blue star as a whole and upgrade directly.


    Of course, Chen Xin doesn''t have so many survival points. Unless he can brush all the refuges in the whole country, it''s impossible.


    However, if we really get to that point, it''s also a difficult choice for Chen Xin whether to choose the universe emperor or the Death Star fortress.


    Fortunately, Chen Xin does not need to consider these things or make a choice. What he has to do now is to consider whether to accept the cooperation proposal of the state.


    After learning that Chen Xin''s ability is not limited by the so-called scope, the eyes of these researchers have been staring like copper bells, and they are almost glowing.


    A postnatal scholar syndrome that has no scope limit and can improve anything. Even if he can''t provide any science and technology, as long as he can provide products, it is the scientific research institutions and researchers who will reverse crack the products he provides.


    Therefore, after confirming that there is no limit to the scope of Chen Xin''s ability, the first cooperation plan proposed by these researchers is naturally to let Chen Xin stay in the three towns, and the state will provide him with the best treatment, and establish a new research institution around him. Chen Xin only needs to improve what the country needs according to the needs.


    However, this kind of treatment similar to being raised in captivity is obviously impossible for Chen Xin to accept.


    If Chen Xin really has the so-called acquired scholar syndrome ability, then this kind of treatment is not unacceptable to him. After all, in this end of life, he can enjoy the special treatment of the country, which is the dream of most people.


    Unfortunately, Chen Xin''s ability is based on survival and system.


    Given special treatment by the state, although Chen Xinhui has a good life and his parents will be well taken care of, it also means that he has lost a certain degree of freedom.


    After all, it is an important existence related to the national strategic planning. I''m afraid Chen Xin will have bodyguards standing guard at the door when he goes to the toilet.


    Under such circumstances, it is much more difficult for Chen Xin to obtain survival points than it is now.


    At that time, he personally improved something to improve other people''s living conditions, so as to obtain survival. The only way for him to obtain survival is for the state to reverse the improvement and promote it, thus affecting other people''s living conditions and enabling Chen Xin to obtain survival.


    This is obviously not acceptable to Chen Xin.


    Chen Xin''s refusal did not exceed the expectations of scientific researchers. In fact, when a country really takes someone seriously, it is not hard to guess what kind of decision you will make after all kinds of psychologists and behaviorists have analyzed it.


    After all, as long as people are not neurotic, their behavior is logical, and once the logic of thinking is seen through and analyzed, it is not difficult to guess what kind of choice they will make.


    Therefore, at the beginning, the project team specially set up for Chen Xin at the space launch center prepared several sets of cooperation plans. The one just proposed is just the most ideal one for the country.


    Chen Xin''s refusal is also in the plan given by the project team, so the scientific research personnel also threw out a second set of cooperation plan.


    Chen Xin cooperates with the state in his own name. The state issues tasks to him in the form of project entrustment. Chen Xin completes the improvement of something for the state, and the state pays Chen Xin according to the results of the improvement.


    This kind of cooperation mode is quite in line with Chen Xin''s mind. The only thing to consider is the payment of remuneration, which is obviously a very good problem to solve.


    After all, the cooperation with Chen Xin is Yanguo, one of the most powerful countries on the blue star. Even for individuals, no matter how astronomical the conditions are, it is nothing for the country.


    What''s more, Chen Xin is not particularly concerned about this issue. The survival that can be obtained by upgrading is what he values most. As for the remuneration paid by the state for an improvement project, it can only be regarded as an addition for Chen Xin.


    Although not as good as not, but also no special value.


    After a discussion has determined a general payment mode, Chen Xin has negotiated cooperation with the state.


    After the negotiation, these researchers can''t wait to take him to the exhibition room where Chen Xin came last time, and see the communication equipment still placed here.


    Obviously, after Chen Xin''s last visit, these researchers carried out reverse cracking on this set of communication equipment, and quickly understood the technology used to improve their things.


    Because Chen Xin is faced with a set of obviously upgraded equipment.


    "Is this the device I improved last time?" Chen Xin asked the researchers.


    "Yes, this is the product that we readjusted according to the equipment that Mr. Chen Xin helped us improve last time. Compared with the previous generation, the performance has been greatly improved. Thanks to the technology that Mr. Chen Xin used, we have been able to make the signal coverage of the base station reach a radius of 60 km." The researchers excitedly introduced their achievements to Chen Xin.Based on the device that Chen Xin improved for them last time, after reverse cracking, although they can''t improve the signal coverage of the device by 30% as Chen Xin did, they also have a significant performance improvement.


    If a large fixed base station is built, it will be enough for two cities not far away to resume communication.


    This is exactly the original purpose of the research and development of this set of equipment, and this goal has obviously been achieved now.


    This is also the reason why the researchers tested the communication equipment before. They need to determine the maximum communication range that the communication equipment can support, and then set up permanent base stations in various cities of the country on this basis, so as to rebuild the communication network.


    However, it is obvious that some of these researchers are addicted to ready-made food. I hope Chen Xin can help them improve it, and then they will continue to reverse crack it.


    This is not to say that these researchers have lost their research spirit, but just want to find the right answers directly, so as to reverse the problem-solving process and reduce the time to explore and find solutions.


    For this kind of request, Chen Xin just thought it over a little and then nodded his head and agreed.


    According to the upgrade requirements given by the system, let scientific researchers prepare materials. Chen Xin also looks forward to how much survival can be brought to him after the national communication network is restored after the equipment is put into use.

    Chen Xin didn''t stay in Sanzhen for a long time. He helped the researchers upgrade their equipment again. Then he got a set of finished products and put them on his car to upgrade the radar on the car to a signal base station. Chen Xin left Sanzhen.


    However, because of the cooperation with the state, his car also had an additional staff sent by a scientific research institution.


    The main task of this staff member is to communicate with Chen Xin, because it is a very troublesome thing to contact Chen Xin from three towns before the communication network is reestablished. Therefore, they must send someone to follow Chen Xin, know where he is, and then establish a stable communication channel through the local official agencies.


    Moreover, after establishing cooperation with Chen Xin, the state also needs to transport upgraded equipment and materials to Chen Xin through local official institutions, which also needs to find out the local transportation, communication, scientific research and industrial production capacity.


    If the foundation of Chen Xin''s city is too poor, it may be necessary to persuade Chen Xin to move to another place or strengthen the local infrastructure. These are all issues that need to be considered.


    Therefore, in order to better cooperate with Chen Xin, the scientific research institutions simply sent their staff to follow Chen Xin for field investigation and find out the specific situation.


    Chen Xin didn''t feel that there was one more person in the car. After the other person got on the car, Chen Xin didn''t care about him. All his attention at this time was attracted by the information obtained from the network after he was connected to the Internet again.


    Because the radar in the car has been upgraded to a signal base station, Chen Xin has been able to access the network that the scientific research institutions are using. Although the network only covers the three towns and the places where he can physically connect with the scientific research institutions in the three towns, Chen Xin still obtains a lot of information from the above through the authority given to him by the scientific research institutions.


    "Statistics of population resettlement in China..." Chen Xin browses the information on the internal network through the console and finds a message with a title that he cares about very much.


    Chen Xin clearly remembers that before the disaster, the national population had reached 1.4 billion, but three months before the meteorite fell, the national refuge plan was expected to accommodate 1.2 billion people.


    According to the information he read on this website, before the impact of the meteorite, only 80% of the country''s population had been taken in.


    It''s a pretty brutal piece of data.


    Of the 1.4 billion people, less than 960 million successfully entered the shelters before the disaster.


    Nearly a third of the population did not enter the shelters.


    Perhaps these people can avoid the first impact of meteorite, but the ensuing rainstorm, the decline of atmospheric oxygen content, extreme cold and low temperature and a series of disasters are enough to make any survivors who do not enter the refuge die.


    The chance that they can survive is already very small, even if someone is still alive, it can only be regarded as survival in the end.


    What''s more, this statistic is accompanied by a list of death rates in shelters.


    Because this is an internal network, the above data are official internal statistics, there is no false part, but it is more uncomfortable.


    According to the above statistics, in the first month of the meteorite impact, the death rate of the population inside the shelter was normal, about 3 ¡ë, much lower than the 7 ¡ë death rate under normal circumstances. After all, most of the people who can enter the shelter are healthy young adults, and they are not so easy to die.


    However, with the passage of time, the mortality rate increased significantly. Three months after the impact, that is, the temperature dropped to below zero, the mortality rate increased significantly, from 3 ¡ë to 8 ¡ë.


    This is not an unacceptable data. On the whole, in the harsh environment of low temperature and severe cold, only this mortality rate is a relatively normal value.


    However, if we consider that the birth rate of newborns is less than 1 ¡ë, and the negative growth of population is more than 7 ¡ë, it will be terrible.


    What''s more, it should be noted that this is the national demographic data, and the total average is calculated.


    However, in fact, the death rate of all provinces and regions is extremely uneven!


    In big cities such as the three towns, because of their good basic conditions and sufficient material reserves, the actual population mortality rate has been maintained at about 1-3 ¡ë. However, before the disaster, they belonged to poor areas. In counties and cities with poor basic conditions, the population mortality rate exceeded 1%.


    In fact, it''s not uncommon for Chen Xin to see a whole county abandoned and hundreds of thousands of people migrate to other areas. Such a large-scale population migration will obviously have an impact on the statistical results of the data.


    In addition to the errors caused by the current communication difficulties, the actual situation will only be worse.


    In addition, Chen Xin learned from his website that the impact of the tsunami caused by the impact of the meteorite and the impact of the global fire have led to the disappearance of all coastal areas below sea level.


    One of the worst hit areas is along the Bohai Bay. The Beijing Tianjin Hebei region, where the capital was originally located, has been inundated by sea water. The central authorities have all been transferred to the Sichuan Basin, and Chongqing, as a municipality directly under the central government, has once again become a temporary capital.The North China Plain no longer exists because of its topography, and the Northeast Plain has also been affected by the tsunami. The whole plain in the middle and lower reaches of the Yangtze River has become a land of glory.


    The four great plains of Yan state are now three of the four, leaving Guanzhong Plain not engulfed by the sea.


    According to the valuable observation data brought back by Zhang Chengguang, the coastline has moved from the original Shanghai stock market to Anhui Province, and the whole Jiangsu Province has become an underwater world under the ice.


    Today, the famous Shandong Peninsula can be taken out of half a word, which is a real island. Other parts of Shandong Province are not so good. They are also separated from the land and become an isolated island. The land can only be seen from the west to Changshan.


    Even more than half of Chen Xin''s hometown, Anhui Province, and Huaibei area in the north, disappeared below sea level.


    On the contrary, the impact on the south is not so serious because of the mountainous relationship. Most areas of Guangdong and Fujian provinces are not submerged by the sea because of the mountainous relationship. Even Zhejiang Province, which is adjacent to Jiangsu Province, has retained most of the land.


    However, most of the economically developed cities in these areas are close to the sea, especially in the Pearl River Delta and the Yangtze River Delta. Because they are close to the sea, they are among the first areas destroyed by the tsunami.


    It can be said that the most important grain producing areas and economically developed areas of Yanguo disappeared in the tsunami impact caused by the meteorite impact.


    As for the melting of glaciers and the rise of sea level caused by the global fire, it is just that the land that has not yet had time to ebb after the tsunami has been completely frozen under the ice.


    If we have a basic understanding of the geography and terrain of Yan state, we can clearly judge that the third step of the three steps of Yan state is only Liaodong hills, Daxinganling, Taihang Mountains, Shandong hills and Southeast hills, and other places no longer exist. With much land and few people, the


    and the Inner Mongolia plateau are the most important examples. The Tarim Basin, to say nothing of the desolate Gobi and desert, is only a Loess Plateau, Sichuan basin and Yunnan Guizhou Plateau.


    Beijing, Shanghai and Guangzhou, once the first tier cities, were all killed in battle. Now only three towns and Chongqing are left in Yanguo, which can be called a super city.


    If it had not been for the evacuation of people from coastal areas inland before the disaster, I am afraid that half of the population would have been lost instead of one third.


    Chen Xin now also understands why tens of thousands of people can move into the towns under his hometown, because the coastline has extended to Anhui Province! A little further east from Anqing is the sea!


    Looking at these data and satellite images, Chen Xin''s heart has been heavy beyond comparison.


    After the disaster, although life is far worse than before, Chen Xin''s life is not bad because of his systematic relationship. In addition, the situation in his city is not too bad to bear. This inevitably gives Chen Xin the illusion that the situation is not too bad.


    Especially after he went to Hubei Province, he saw that the country was carrying out post disaster reconstruction in full swing in the three towns. He even felt that the apocalyptic disaster was nothing. The difficulty was only temporary, and everything would be better.


    But now, seeing that one tenth of the country''s land has sunk under the sea, one third of the population has disappeared when the disaster hit, and all the economically developed coastal areas have been destroyed by the tsunami, Chen Xin clearly feels that this apocalyptic disaster is the real end of the world.


    In fact, even Chen Xin''s city, because of its proximity to Dongting Lake, was flooded with seawater when the tsunami came. The area of the whole lake area has expanded to the extent of yunmengze in ancient legend.


    If it wasn''t for the hilly terrain of Chen Xin''s city, I''m afraid it would be like the Poyang Lake area in Jiangxi Province next door.


    Chen Xin can''t help sighing that the civilization that human beings have spent thousands of years to build is like a castle on the beach in the face of the last natural disasters, which is easily destroyed when the waves come.


    For Yanguo, most of the achievements in economic construction over the past few decades have been wiped out in this disaster, and everything seems to have regressed for decades.


    This can not help but make people worry, can we really overcome the immediate difficulties and rebuild our homes in this disaster?


    Chen Xin thought seriously, but he didn''t despair.


    For Yan people, we have experienced too much suffering since ancient times, but we have never been knocked down by the disaster.


    When the sky is broken, you can mend it by refining stones; when the flood comes, you can dredge the river without asking the prophet; when the disease is prevalent, you can try medicine and cure it by yourself without asking for miracles; when you drown in the East China Sea, you can fill it up, and if you are exposed to the sun, you can shoot down the sun; in the face of disaster, there are always Yan people who will die.


    Just like the old saying before the flood, the people of Yan country are invincible! We will be able to overcome all suffering and rebuild our home!

 Chapter 269

    In the shelter in the early morning, Chen Xin had already made breakfast. Seeing Qin LAN coming out of the room, he naturally asked her, "a LAN, are you still used to using your hands?"


    Hearing Chen Xin''s question, Qin LAN raises her right hand, with complicated eyes.


    Her right hand is no longer original, but a prosthesis made of carbon fiber with large black and red lines as embellishment, and a red metal glove matching with the prosthesis is placed on one side of the table.


    "I''m not used to it, but it''s much better than before." Qin LAN moved her fingers and answered to Chen Xin, "the touch of prosthesis is still a little strange."


    Qin Lan''s impression of Chen Xin''s prosthetic limb is complicated and has some small emotions, especially when Chen Xin comes back and makes her second hand.


    In fact, when Chen Xingang came back, he heard that Qin Lan was very worried about her because she lost her right hand.


    However, in order to arouse Qin Lan''s desire for survival, Chen Xin deliberately said to Qin LAN, who was ready to say goodbye to the world when Chen Xin came back, with a very indifferent attitude: "isn''t it just a hand? I''ll make one for you and it''s over! "


    Such words, combined with Chen Xinyi''s completely indifferent attitude, make Qin LAN angry.


    In order to see Chen Xin again, she supports herself until he comes back, but Chen Xin doesn''t care about her, which is undoubtedly a great shame for Qin LAN, and even makes her forget about her suicide.


    I want to live and die for you, but you don''t care? "It''s just a hand." do you think it''s easy to make a prosthesis?


    Qin LAN with anger, want to see Chen Xin is how to do a hand out, the result for Chen Xin, this is really just to do a finished thing.


    Qin Lan''s intact left hand was measured with a tape measure, and the dimensions, modeling, flipping, composition and design were recorded. Then it was input into the workbench and materials. A brand-new metal prosthesis was made in this way, and then it was spent by Mo Qingxin in the operating room. About half an hour later, it was installed on Qin LAN.


    "This hand is only made temporarily. You can make do with it first. After a while, I''ll get some carbon fiber materials to make a better one for you."


    Qin LAN still remembers what Chen Xin said when he saw the prosthesis installed and walked out of the operating room, which made her feel that for Chen Xin, it really didn''t seem like much.


    While adapting to her right hand, which is much heavier than before, Qin Lan''s original ambition to die is also diluted by anger.


    After calming down and giving up her will to die, Qin LAN finally reacts that Chen Xin deliberately angers her and makes her not think about suicide because she is angry.


    Because Chen Xin knows Qin Lan''s character very well until she is very strong. If Chen Xin shows compassion and sympathy, it will only hurt Qin Lan''s self-esteem and make her feel more and more like a drag and want to commit suicide.


    But if Chen Xin doesn''t care about her performance, she feels that she is dying for this, which can stimulate Qin Lan''s desire for survival.


    After that, Chen Xin quickly fulfilled her promise to rebuild a carbon fiber prosthesis for her and a red power glove for her right hand.


    It''s just because she knows all this and understands how much Chen Xin has done for herself that Qin LAN has a complicated impression of her prosthesis, because she still feels that she is a drag on Chen Xin. Even though the carbon fiber arm Chen Xin made for her is no different from her original arm in terms of flexibility and sensitivity, even better.


    Qin LAN knew that it was Chen Xin who had such a prosthesis.


    If there is no Chen Xin, she is still the one who broke her hand. In the end of the world, when everyone is struggling on the line of life and death, she has no choice but to wait for death.


    Maybe the police will arrange a relatively simple job for her, which can be completed with one hand, so that she can do something, at least not to die, but this is unbearable for Qin LAN.


    She can''t bear to be the object of pity and sympathy for her pride, and she can''t bear to be a person who can''t even take care of herself and needs to be taken care of by others.


    But Chen Xin gave her a second chance, a delicate and flexible prosthesis, so that she could put down the sleeve of her right hand and put on gloves, which was no different from that before she was injured, and this hand was no worse than her original hand. Wearing the power gloves specially made for her by Chen Xin, she could even dismantle the civil vehicle with bare hands.


    But the better this hand is used, the more Qin LAN feels that she owes Chen Xin a lot.


    Because of this debt mentality, Qin LAN didn''t return to the police force, but stayed with Chen Xin all the time. She knew that as long as she still used this hand, she would never know Chen Xin''s kindness.


    For Qin Lan''s mentality, Chen Xin also feels helpless, but does not think it is a good thing.


    After all, Qin LAN is a professionally trained sniper. In terms of personal quality and combat effectiveness, she is even stronger than Han Ping, a veteran. In particular, Chen Xin has made her power gloves, which is to build her to an inhuman level.Qin LAN has been staying here with a sense of debt, which can be said to have added a valuable strength to her refuge.


    Maybe it''s suspected of taking advantage of others'' danger, but Chen Xin can''t do it. He can''t watch Qin LAN commit suicide because of the broken arm.


    Now the result should be the best for her and Chen Xin.


    So now both of them didn''t mention it, just discussed the use of the prosthesis peacefully.


    "It feels strange. Do you think it''s ok? I didn''t think there was any difference between a little cold and a little hard last night. " Chen Xin puts a breakfast in front of Qin LAN.


    Hearing Chen Xin''s words, Qin Lan''s face turned red. She twisted Chen Xin''s body with her left hand and said, "don''t say it! Do you know how hard it is to wash! And you''re not afraid your parents heard that? "


    "Did they hear that? I think my mother only cares when you marry me. " Chen Xin, with an indifferent bad smile on his face, deliberately teases Qin LAN.


    In the face of such words, Qin LAN can''t go any further. She can only eat her breakfast with her head down. At this time, Mo Qingyan, Mo Qingxin and Chen Xin''s parents also come to the table one after another to prepare for breakfast.


    "Xinxiaomei, go up there and call Hanping. They''ve come down for breakfast." Chen Xin takes a look at Mo Qingxin and tells her.

 Chapter 270

    According to Chen Xin''s original arrangement, Han Ping and Han Ze also live in the lower room of the shelter.


    However, as a brother, Han Ping, after a detailed understanding of the structure of Chen Xin''s refuge, said that he would live with his brother at the entrance of the upper floor as a guard and guard.


    "Mr. Chen, if everyone lives underground, in case something happens up there, it may be too late to come up. So we should still arrange sentries at the entrance, so that we can report anything in time. "


    This is Han Ping''s original words, and Chen Xin agreed to his remarks after considering them.


    While Han Ping and Han Ze were allowed to live on the upper floor as gatekeepers, Chen Xin also transformed the observation room, adding a bedroom for the two brothers.


    Although there is a feeling that the two brothers are excluded from the core team, it is Han Ping''s own request, so he doesn''t think so either. Instead, he thinks it''s better and he can play his role better.


    After all, in Han Ping''s opinion, he and his younger brother have no talent. In Chen Xin''s place, apart from being a driver for him and doing some chores, the only role they can play is to be a security guard and a guard.


    Chen Xin naturally respects Han Ping''s choice, and it''s a good thing for Chen Xin to do so, because the safety of the refuge is much better than before, and if someone comes, Han Ping can receive him in time, so as not to need Chen Xin to open the door from below as before.


    But the corresponding Han Ping and Han Ze brothers have to be called or sent to eat every day.


    Everyone finished their breakfast and began their day''s work.


    Mo Qingyan and Mo Qingxin are now living in Chen Xin, but they have not returned to their shelters.


    So now Mo Qingxin stays in the infirmary every day, which seems to be a tacit admission that she is a doctor in the shelter, while Mo Qingyan is responsible for Chen Xin''s greenhouse every day, which seems to be the person in charge of the greenhouse.


    Chen Xin can only acquiesce to this. After all, the two sisters have been helping themselves to take care of the shelter before. Now they are willing to stay. Of course, Chen Xin has no opinion.


    As for Chen Xin''s parents, Chen Xin didn''t arrange anything for them, but the two old people are obviously restless. Chen Xin''s mother cleans up the shelter every day, which makes the sanitation and tidiness of the shelter visible to the naked eye.


    Chen Xin''s father has no fixed tasks. Sometimes, he helps with cleaning under Chen Xin''s mother''s instructions. Sometimes, he cooperates with Chen Xin to help with mechanical processing in front of the workbench. Occasionally, he also helps with planting greenhouses.


    Chen Xin himself now needs to contact the scientific research institutions that have established network connections every day to assist them in the research of related projects.


    Qin LAN can''t help Chen Xin in this kind of thing, and she is not very good at other aspects, so her only job is to take care of the hens and the eggs Chen Xin brought back every day besides planting greenhouse to help Mo Qingyan.


    Because the hens were allowed to brood, and Chen Xin was able to ensure the incubation temperature, after more than 20 days of incubation, the chicks were able to break their shells and hatch successfully. It seems that only one egg failed to hatch because of some problems.


    Qin LAN showed a great deal of maternal and gentle attitude towards these chicks, and took good care of them every day.


    And because she was afraid that her right hand would be too hard to hurt the chicks, she only touched the chicks with her left hand every time to avoid hurting them.


    For Qin LAN, she felt the beauty of life through these chicks. Every day, watching these new lives growing up, the last trace of decadence and death will disappear in her heart.


    However, this also leads to a problem that Qin LAN squats in front of the chicks'' incubator every day, and looks at it all day, even protecting her chicks more than an old hen.


    Chen Xin can''t help laughing and crying about this, but seeing that Qin LAN can come out of the shadow before, Chen Xin will follow her.


    After confirming the location of Chen Xin''s refuge, the staff of the scientific research institution who came back with Chen Xin got in touch with the municipal government, contacted the three towns through the municipal government, and soon established a branch of the scientific research institution in the urban area.


    The main task of this branch is to connect the scientific research institutions and Chen Xin. Before the communication tower was established, the communication network was not connected. Chen Xin could not directly contact the scientific research institutions. This requires this branch as a relay to communicate the connection between the two.


    The scientific research institutions will send the upgraded equipment and related project requirements to the branch offices in the urban area, and the branch offices will send things to Chen Xin after receiving the equipment and project requirements.


    After receiving the equipment and project requirements, Chen Xin will observe the equipment through the system according to the project requirements and put forward the materials and resources he needs.After receiving Chen Xin''s request, the branch will transfer Chen Xin''s request to the scientific research institution, which will allocate the materials and Resources Chen Xin needs, and send them to the urban railway station at the first time.


    After receiving the goods, the branch will transport the goods to Chenxin in time. After Chenxin has finished upgrading the equipment, it will drag the equipment back and send it back to Sanzhen by train.


    After handing over the upgraded equipment, in theory, Chen Xin''s work in this project is completed, and the rest is the scientific research institutions'' reverse technology cracking of the upgraded equipment.


    Of course, technology cracking is not an easy or short-term task, so the scientific research institutions in charge of contacting Chen Xin in the three towns do not do it themselves, but subcontract the project to other branches or scientific research groups below, and they are mainly responsible for organizing and coordinating, confirming the priority of the project, and judging what project should be the first The time is sent to Chen Xin for upgrading and optimization, and what projects need to be called back to let those research departments work by themselves.


    On top of the scientific research institution, there is a special project team, which will be responsible for coordinating the links between the scientific research institution and the logistics department, as well as other relevant departments.


    Because a project involves quite a lot of departments, scientific research institutions alone can not coordinate these things, and scientific research institutions themselves should not waste their energy on the coordination of various departments, so these work naturally rose to a higher level of special groups.


    The special group at a higher administrative level also has greater power to better coordinate these work.


    After all, a project involves not only the R & D Department of the project, but also the relevant production department and the final user. Many of these things need special groups to coordinate and communicate.


    What''s more, Chen Xin doesn''t know what materials he needs when upgrading the equipment. He will give a list only after seeing the equipment. It''s not a simple matter to allocate the materials and supplies he needs in the shortest time.


    Although the special group and scientific research institutions have mobilized a wide range of materials because of the consideration of cooperation with Chen Xin in advance, sometimes the materials Chen Xin needs can not be deployed immediately in a short time.


    Sometimes they even need to contact a special factory to customize for Chen Xin.


    Although for Chen Xin, whether there are materials or not is just a matter of survival consumption, since he cooperates with the state, and the other party can allocate a large number of materials and meet the corresponding types of needs, Chen Xin naturally does not need to use low-grade materials to replace high-grade parts, or simply use ten times survival to meet the upgrading needs.


    And it''s not a bad thing for the country.


    Because the materials and materials Chen Xin needs are actually applied to the upgraded equipment. Knowing what materials Chen Xin needs in advance can also allow the special team to confirm what raw materials are needed after the equipment is put into production, which can better coordinate the production, organize the production of raw materials, and save the preparation time from equipment finalization to production .


    In the half a month since Chen Xin returned to his refuge, more than a dozen projects have been optimized and upgraded here and sent back to three towns for reverse cracking. Five of them have completed reverse work and started production.


    One of the most important natural is the communication base station project. This project, which has been upgraded twice by Chen Xin, now has enough practical value and performance. It has not only been finalized and transferred from scientific research institutions to production departments, but also has permanent communication towers in three towns and the city, Chibi City and Xianning City between them.


    Obviously, after the communication base station project was put into practice, the first thing the special team thought of was to establish contact with Chen Xin.


    For Chen Xin, this is what he is looking forward to. To be able to resume network communication again after such a long time, even if it is only connected to the internal network of scientific research institutions, not to the civil network, is also good news for Chen Xin.


    In addition, Chen Xin can get quite rich rewards for cooperation in every project. For him, it is no doubt a business that makes no loss.


    Moreover, after the establishment of the communication base station, it also means that the living conditions of the city where the communication base station is located have been improved, and a large amount of survival income is waiting for Chen Xin.


    Now, he is only looking forward to more projects, not too many things.

 Chapter 271

    "Mr. Chen, about the isotope thermoelectric battery, the project team put forward new requirements, hoping to develop a small battery." A staff member stood in front of Chen Xin with a document and informed him of the latest project requirements.


    Listening to the other party''s request, Chen Xin didn''t think there was any problem, just confirmed the specific requirements to the other party: "small battery? How small is it? What are the performance parameters? "


    The size and weight of the isotope thermoelectric battery originally made by Chen Xin is not very big, which is almost the size of a water bottle. One can carry it around. Now he wants to make a smaller battery, which inevitably makes Chen Xin wonder how small they want to make.


    "On this point, the request from the project team is to make a large thermos cup that can be carried easily by individual soldiers, with the size of 20cm in height and no more than 10cm in diameter, which is almost the size of a large thermos cup." The staff opened the file in hand and read the specific requirements: "the rated output power of the battery shall not be less than 30kW, and the service life shall not be less than one year. The battery can be overloaded to improve the instantaneous output power at the cost of reducing the service life. In addition, there are no other requirements."


    With these words, the staff also handed the documents to Chen Xin.


    After listening to the request read out by the staff, Chen Xin took the document he handed over, looked through it a few times, and said with great interest: "this small size, do you want to use it on individual power armor?"


    "This The project is highly confidential, and we only know the performance requirements. We don''t know what to apply to. " The staff were unable to answer Chen Xin''s questions. Although he was able to access some highly confidential information because he needed to be responsible for the relationship with Chen Xin, he was not authorized to know anything.


    For the staff''s answer, Chen Xin shrugged his shoulders, shook his head and said, "OK, if you don''t know, you don''t know. Did you send the prototype?"


    "Yes, the relevant prototypes have been sent. The priority of this project is level 1. We will give top priority to any needs you have." The staff quickly asked the people around them to send in a small container. Then they opened the container and showed Chen Xin the prototype of a small isotope thermoelectric battery made by the relevant project team.


    Chen Xin is not surprised that the country has been able to make small prototypes of isotope thermoelectric batteries so soon. With his isotope thermoelectric batteries as a reverse reference, the country itself has accumulated technology in this area, so making small prototypes is not a problem.


    However, it is obvious that the isotope thermoelectric battery of this small prototype can not meet the design requirements in all aspects of performance, otherwise it will not be sent to Chen Xin.


    "It seems that you have made good progress in the research of isotope thermoelectric battery. When can you put it into practical use?" Chen Xin is still very concerned about this. After all, once the isotope thermoelectric battery is put into use in all aspects, it can bring Chen Xin a lot of survival income.


    To this point, the staff is not easy to answer, and he does not know much about the relevant project process, so he can only answer: "I am not very clear about the specific situation, but since the prototype of small battery has been developed, it should be fast?"


    "Well, it seems that the progress is slower than I expected." Chen Xin didn''t care about it either. After all, it''s scientific research, not the production of skills in the game.


    Han Ze was asked to reload the small container and send it to the studio below. At the same time, Chen Xin also said to the staff, "I''ll study it first. I''ll let you know what materials I need later."


    "Well, Mr. Chen, let''s leave first." With that, the staff politely said goodbye to Chen Xin and left Chen Xin''s shelter with others.


    After these people left, Han Ping was about to close the door, but Chen Xin stopped him and said to him, "get ready, go out with me and call ah LAN by the way."


    "OK, I''ll get ready." When he heard that Chen Xin was going to go out, Han Ping didn''t ask where Chen Xin was going, so he went directly to prepare for going out.


    Where are we going Qin LAN, who is called out by Chen Xin, is a little surprised why Chen Xin wants to call himself out together.


    "Go to Bruce Lee. He''s officially running now, so go and have a look." Chen Xin answers Qin LAN and explains to her: "you''ve been at home all this time. I''m afraid you''re in a bad mood, so I call you to come out and have a look."


    "Thank you. Is it lonely to go out on such a dark snowy day?" For Chen Xin''s words, Lan Qin could not help but make complaints about it.


    "That''s not what I said. I''m afraid you''re suffocating." Chen Xinchong Qin LAN smiles, but he soon corrects himself and asks Qin LAN, "in addition, I just want to ask a LAN what do you think of power armor."


    Chen Xin''s question surprised Qin LAN and asked: "power armor? What''s in science fiction movies? What''s the point of saying that? ""Yes, because I think the country should be developing this thing. Moreover, it''s not difficult for me to make a set of usable power armor, so I want to ask you, if I make a set of power armor for you, what functions do you think it should have and what requirements should it meet? " Chen Xin answers to Qin LAN and does not hide his thoughts.


    "Xin, can you really make power armor?" Qin LAN couldn''t believe it, but after Chen Xin gave her a positive answer, she thought it over carefully and said, "it''s the most important thing to provide systemic protection, isn''t it? Second is Environment scanning, battlefield support?


    It''s hard for me to answer if you ask me that for a while, but personally, from the perspective of game experience and actual combat, I hope to have the concealment function and provide aiming assistance. For snipers, these two should be the most important ones, right


    "Yes? So, Alan, what do you think of the specialized power armor Chen Xin is not surprised. After all, Qin LAN is a sniper. Her needs must be based on her own experience and put forward relevant requirements.


    After asking Qin LAN, Chen Xin looks at Han Ping who is driving and asks him, "Han Ping, what do you think?"


    "Ah? I? I don''t know! " Han Ping didn''t respond for a moment, and he didn''t know how to answer.


    "By the way, you''ve heard of power armor, haven''t you? If you were given a power armor, what functions would you like to have? " Chen Xin did not let Han Ping go, still want to hear his opinions.


    "This..." Han Ping got into thinking, but after thinking about it, he didn''t have any idea. He just tentatively replied, "can I run faster, jump higher, and have more strength?"


    "Faster, higher, stronger? It''s a very average idea Chen Xin didn''t think Han Ping''s answer was perfunctory, but thought it was of great reference value.


    Perhaps Han Ping thought his answer was too simple. After racking his brains, he added: "when I was a soldier, what I was most afraid of was the load-bearing cross-country after the emergency assembly. If I could carry more heavy things and carry more ammunition, I think this should be a more practical choice?"


    "I think this is reasonable. For ordinary soldiers, carrying more ammunition and equipment is the key to enhancing their battlefield survival ability." Qin LAN makes a sound and agrees with Han Ping''s suggestion.


    Although he is a sniper, Qin LAN still knows the needs of ordinary soldiers on the battlefield.


    After listening to Han Ping and Qin Lan''s suggestions, Chen Xin nodded and said summarily: "in your opinion, a set of power armor should at least improve the user''s speed, load-bearing and defense ability, so that the user can carry more materials, persist in the battlefield for a longer time, and have good protection at the same time?"


    "These should be basic. If they are classified and specialized, such as snipers, blasters or attackers, they should be classified and strengthened according to different uses." Qin LAN added again.


    "Yes, I''ll design a basic model first, and then improve it according to the basic model." Chen Xin nodded his understanding.


    Qin LAN didn''t doubt Chen Xin''s words after he said that he could make power armor. Instead, Han Ping, who didn''t know enough about Chen Xin, asked curiously, "Mr. Chen Xin, can you really make power armor? The development and manufacture of this kind of thing is not personal, is it? Isn''t this the only technology a country can have? "


    "That''s right, but it''s not as difficult to make power armor as you think." After listening to Han Ping''s question, Chen Xin also showed curiosity. Chen Xin just laughed and explained: "the manufacturing of power armor itself is not complicated. The core is just hydraulic transmission and structural support. Even with all kinds of functions, as long as you have relevant knowledge, even individuals can complete the design, production and assembly in private workshops It''s loaded.


    Before the disaster, in fact, countries were already developing power exoskeletons and other things, which were actually the unprotected version of power armor.


    It''s actually the energy problem that really restricts the development and application of power armor. It''s the same with the power exoskeleton. Charging can only take a few hours or even more than ten minutes at a time. That kind of thing has no actual combat value. "


    "So when ah Xin made the isotope thermoelectric battery to solve the energy problem, it became inevitable that this kind of thing, which was originally on paper and in the laboratory, would be applied quickly?" Qin Lan said the key answer.

 Chapter 272

    Chen Xin didn''t think about power armor for long. For him, it''s nothing more than how to do it, rather than the problem of not being able to do it.


    So after consulting Qin LAN and Han Ping, Chen Xin put it down.


    Han Ping soon drove the car to the small shelter where Li Yulong lived according to Chen Xin''s instructions. It has been operating again during the period when Chen Xin left. Now the trading market that Li Yulong had imagined has also begun to operate.


    Although it seems that there are still a few things left to do, Chen Xin knows that the business here is not bad.


    However, when entering the shelter, there was a small problem, that is, after two upgrades, Chen Xin''s RV has become extremely high and wide, which is comparable to that of a large container truck. If it is difficult to get on the road before the disaster, now it has no way to enter the shelter.


    Facing this situation, Chen Xin can only take Qin LAN out of the car, walk into the shelter, and leave Han Ping in the car to watch the car.


    "It seems that a Xin, you need to prepare a car for going out at ordinary times. Now it''s OK for you to go out for a long time, and it''s a burden in the urban area." Qin LAN and Chen Xin enter the shelter. She looks back at the tracked RV parked at the gate of the shelter and says to Chen Xin.


    Chen Xin nodded slightly, for this problem he also realized: "back again, now this demand is not urgent."


    "Well, you can do it as you like. It''s no trouble to get a car anyway." Qin LAN, who knows something about Chen Xin''s current situation, didn''t say much about it. For Chen Xin, if he just wanted a scooter, he said that someone would send it to him.


    They went through the cold trading area and came to the area inside the shelter. Li Yulong, who had been waiting for a long time, saw them and immediately welcomed them.


    "Brother Chen, sister Qin, here you are!" Li Yulong is very enthusiastic and seems to be very happy with the arrival of Chen Xin and Qin LAN.


    "Long time no see, Bruce!" Chen Xin said hello to Li Yulong, looked around and then asked him, "how''s business recently? It seems that a lot of things have been sold out! "


    "Ha ha, it''s not thanks to brother Chen. I can''t run this business without your help." Li Yulong responded warmly and politely to Chen Xin.


    Qin LAN looked at the polite two and said with a smile: "Bruce Lee, you won''t let us just stand and talk, will you?"


    "Look at me! Sorry, sorry! Sister Qin and brother Chen, please come inside! " Li Yulong pats his forehead and makes a gesture to Chen Xin and Qin LAN.


    Under the leadership of Li Yulong, Chen Xin and Qin LAN come to a room in the shelter with him, and then sit down on the sofa.


    The room was obviously elaborately arranged by Li Yulong.


    Although not to mention how luxurious the decoration is, compared with the ordinary shelter, which is directly concrete walls, there is no furniture decoration, and even the lighting is just a fluorescent tube room with insufficient brightness, this room is pasted with wallpaper, carpets, sofas, tea tables and wine cabinets, and even the lamps are soft and bright. The decoration is very good It''s too late.


    Before the disaster, such a room was nothing, but in today''s end, it is a symbol of power and wealth to maintain such a room.


    Of course, in a sense, this so-called symbol of power and wealth is meaningless. Hunger is not edible and thirst is not drinkable. This so-called symbol of power and wealth can not be exchanged for a better life in this last world.


    The power and wealth that can support all this behind is the real important existence.


    For Li Yulong who owns all this, Chen Xin is the important existence behind him.


    So after Chen Xin and Qin LAN sat down, Li Yulong quickly asked his men to bring wine and snacks. After pouring a glass of wine for Chen Xin and Qin LAN, Li Yulong talked to Chen Xin about business.


    "Brother Chen, in the month after you came back, eight of the 20 ground source heat pumps you provided were sold, while more than 300 bottles of strawberry jam and more than 200 pieces of wine bricks we prepared in advance were sold. Judging from the current situation, the market has not yet opened." Li Yulong told Chen Xin about the sales this month.


    Hearing what Li Yulong said, Chen Xin nodded slightly, took a look at the snack made of strawberry jam on the table, handed a piece to Qin LAN, and asked Li Yulong, "who are the main customers to deal with?"


    "It''s mainly people in private shelters. After all, the people who can come to buy things are those who have surplus goods on hand." Li Yulong took the sales list and handed it to Chen Xin before he continued: "all the eight ground source heat pumps were sold to private shelters, and strawberry jam was also purchased by these people. People in the official shelters knew that there were some people who came to this place sporadically, but they didn''t have much materials to trade, and their purchasing power was not strong."


    "It''s expected that if you want to do business, you have to be able to trade directly with the official shelters." Chen Xin is not surprised by this situation.Li Yulong also agrees with this, but he is also bitter to Chen Xin: "but it''s not easy to deal with the official. Although my father helps to dredge the relationship, the municipal government seems to ignore our output. Because of Qin Jie''s injured relationship, the municipal police station is now out of touch, and it''s hard to communicate.


    So the current situation is a bit difficult, but I believe it is temporary. Our commodities are hard currency. I believe that with the opening of the market, our business will be better and better. "


    "I don''t doubt that, but Bruce Lee, have you lost contact with the Municipal Bureau? Even if Alain is not in the SWAT team, you can go to Xiaoding, right? She''s captain Ding''s daughter. How can she help you? " Chen Xin looks at Li Yulong and doesn''t understand why he doesn''t go to Ding Ning.


    Facing Chen Xin''s question, Li Yulong was embarrassed and didn''t know what to say: "this I I don''t dare to see Ding Ning


    Hearing this, Chen Xinzheng was puzzled, but Qin LAN laughed: "why, Bruce Lee, do you still remember that a Ning threw you into the river last time? How can a big man be so timid? "


    "Sister Qin, it''s not timidity, it''s psychological shadow!" Li Yulong laughed bitterly.


    Qin LAN scoffs at Li Yulong''s so-called psychological shadow, but he doesn''t say much. He promises to help him find Ding Ning.


    Chen Xin is also mentioned by Qin LAN. She remembers that Li Yulong was thrown into the river by Ding Ning because he molested Ding Ning''s friends.


    Strictly speaking, Li Yulong is not teasing each other. It''s just that the second generation of the rich see their beautiful little sister and want to have a little more than friendship with each other. As a result, they annoy Ding Ning and are pushed into the water by her neck.


    Obviously, for Li Yulong, it''s a bit of a blow to him.


    But Chen Xin can see that Li Yulong''s words are just excuses. He wants to get through the relationship with Uncle Ding through him and Qin LAN.


    After all, he went to find Ding Ning himself. Even if he could get through the relationship, it would not be as good as Chen Xin and Qin LAN.


    Chen Xin naturally understood this, so he didn''t care about Li Yulong''s small calculation, and acquiesced to Qin Lan''s promise to help him get through the relationship.


    Having said this, the three people also changed from formal talks to small talk, and naturally they talked about the power armor that Chen Xin and Qin LAN talked about before.


    Li Yulong naturally shows great interest in power armor. If this kind of thing can be sold here, it will be more powerful than ground source heat pump, and it will soon make his little-known trading market take off quickly.


    However, Chen Xin poured cold water on Li Yulong''s expectations: "don''t think about this kind of thing. The state can''t let private people control power armor."


    "Well? Do you still make it yourself, brother Chen Li Yulong can''t understand the situation.


    Chen Xin shook his head to him. Li Yulong didn''t know about Chen Xin''s cooperation with the state, and Chen Xin didn''t answer his doubts. He just said to him, "I have my own way. It''s no problem to make two sets by myself, but it''s a problem to let you sell them. So don''t think about it."


    "Ah? What a pity Li Yulong can''t help but feel sorry that if he can have power armor as a fist product, his development plan will flourish like adding rocket thrusters, and he doesn''t need to sell strawberry jam as slowly as he does now.


    Chen Xin didn''t comment on Li Yulong''s ambitions and ideas, but he didn''t strike him too hard. After all, Li Yulong is his partner. The better Li Yulong can develop, the better for him.


    So after pouring cold water on Li Yulong, Chen Xin said to him, "it''s impossible to make power armor, but exoskeletons and protective clothing are still available. It''s similar to the cold protective clothing and basic exoskeletons worn by ordinary workers in wandering earth. This kind of civilian things can be sold."


    "Exoskeleton? Protective clothing? Brother Chen, can you do it? " Li Yulong''s eyes lit up like a light bulb.


    "I can do all kinds of power armor, not to mention the beggars'' exoskeletons and protective clothing? It''s just a matter of drawing a few drawings and using brain cells. " Chen Xin is very confident, and it''s really not difficult for him.

 Chapter 273

    Chen Xin didn''t stay long with Li Yulong. After chatting with him, he took a look at the greenhouse and picked Qin LAN a small basket of strawberries and two wine bricks. Chen Xin and Qin LAN left Li Yulong.


    "Do you want to go to Xiaoding now?" Back in the car, Chen Xin asks Qin Lan that she has just agreed to help Li Yulong get through the relationship with Ding Ning. Chen Xin thinks that she may want to see Ding Ning.


    However, Qin LAN shakes her head, washes the strawberries and puts them on the table at the Liuli terrace, sits down, picks up one and throws it into her mouth. Then she says, "it''s not urgent. To tell you the truth, what Bruce Lee sells there is not much need for the SWAT team. Fresh fruit, jam, wine These things are not necessities of life, and now they belong to the category of luxury goods.


    Even if I ask Anning to help dredge the relationship between the captain, the team''s purchase of these things, the amount will not be very large. So it''s not something to worry about. It doesn''t matter to see Anning next time. Let''s go back today. "


    Hearing Qin LAN say so, Chen Xin also doesn''t think so, nodded to signal Han Ping to drive back.


    As Han Ping drives back, Chen Xin looks at the strawberry Qin LAN is eating on the table, and suddenly laughs, with a strange expression on his face.


    Seeing the expression on Chen Xin''s face, Qin LAN asked curiously, "what''s the matter? Think of something funny? "


    "No, I just think it''s a bit ironic. Now most people should still have enough to eat for three meals, but we can eat fresh fruit as before. It''s really..." Chen Xin couldn''t think of any suitable adjectives, so he could only shake his head helplessly.


    Before the disaster, although Chen Xin''s family was not poor, it was not a rich family. He never thought that one day he would live a better life than most people.


    "What do you mean by that? Ah Xin, even if you are worried about the country and the people, you don''t feel that you need to lower your living standards to share weal and woe with others, do you Qin LAN picked up a strawberry and put it into her mouth.


    Chen Xin nodded, affirmed Qin Lan''s words, and then explained, "I''m thinking about the plantation that I discussed with Bruce Lee before. If I can, build a large-scale greenhouse plantation and get a lot of food and other crops. This is the way to improve other living conditions."


    "That''s right. You should be able to do it. How do you want to start? Do it yourself or cooperate with the country? " Qin LAN looks at Chen Xin and thinks that he has a lot of ideas today.


    Chen Xin naturally noticed Qin Lan''s idea and explained with a smile: "I haven''t come up with a plan before I think about how to do it. But now I have a general idea."


    "Oh? Can you tell me about it? " Qin LAN suddenly came to the interest, very want to listen to Chen Xin.


    Chen Xin nodded, reached for a strawberry and put it in his mouth. Then he said, "I plan to complete the Commission of miniaturization isotope thermoelectric battery, lay the foundation for the development of power armor and exoskeleton protective clothing, and then complete the exoskeleton protective clothing that can be used for civilian use, and then consider the establishment of large-scale planting greenhouse."


    "It''s really your style, step-by-step plan." Qin LAN is not surprised by this. Although Chen Xin sometimes has many ideas, he will never let all ideas come together. Instead, he will have a plan to let things come one by one.


    However, Qin Lan was still very curious and asked: "I can understand that you develop miniaturized batteries first, but why don''t you develop power armor, but civilian exoskeleton protective clothing first? Does that have anything to do with building a large greenhouse? "


    To this question, Chen Xin gave a very positive answer: "yes."


    Seeing Chen Xin say so, Qin LAN didn''t ask him to answer immediately. Instead, he went through his head and thought about it for a while before saying: "the biggest function of exoskeleton protective clothing is to resist the harm of bad environment and low temperature to human body.


    Taking the movie "wandering earth" as a reference, it should also be able to provide oxygen, so as to ensure that users can also engage in heavy physical work in the current environment where the oxygen content is not as good as before.


    In addition, the exoskeleton itself is a kind of power assisted machine, which can enhance the power of the user, lift heavier things, and achieve higher labor efficiency.


    So shin, you need to develop exoskeleton protective clothing first to enable people to move and work freely in the outside world, right? Are you going to build a large greenhouse on the surface? "


    "Well, that''s right." Chen Xin nodded and then explained: "the underground space is limited. Now most of the underground space is used for living. If you want to plant crops in a large area, there is no place and the cost is too high. If you build a large-scale greenhouse on the ground, the planting area and cost will be relatively small."


    "And according to the forecast, the dust will fall in the next few years, the sun will gradually recover, and the use of fill lights will be reduced accordingly, saving operating costs. It is really better to build on the ground than underground." Qin LAN contacted the information she had recently obtained through Chen Xin and nodded clearly."Yes, that''s what happened. And I''m afraid it should start as soon as possible, because although the country''s grain reserves can last for several years, there will be a crisis of grain shortage in the future. Therefore, it is also very important for the country to resume grain production as soon as possible. " Chen Xin is still worried about the food problem in the future. Although he is not worried about it, it is very important for the country.


    "But how much can greenhouses do?" Of course, Qin LAN can understand Chen Xin''s worries, but she doesn''t have much confidence in how much food the greenhouse can grow and whether it can meet the future food needs.


    However, Chen Xin only gave a serious answer to this question: "it''s better to save one than to save one. Now we have a variety of rice, and we can support one more person in the future. It''s better than nothing."


    At this point, Chen Xin seems to feel that it is a bit impractical to say so, and added to Qin LAN: "moreover, I only solve the difficulty of large-scale construction of greenhouse. It''s the country that really promotes large-scale ground greenhouse. I just do what I can do."


    "That''s great. If everyone can do what they can, it''s enough to change the world." Qin LAN chuckles at Chen Xin and pinches his hand on his face.

 Chapter 274

    Back in the shelter, while Chen Xin is busy miniaturizing the isotope thermoelectric battery, he is also seriously thinking about how to do the exoskeleton protective clothing.


    The manufacture of exoskeletons is a very simple thing for Chen Xin. In fact, it is not difficult to manufacture a set of exoskeletons even for Yan Guo.


    Before the disaster, a variety of exoskeletons have been put into use, not only in the military, but also in the delivery delivery brother.


    However, this kind of exoskeleton belongs to passive exoskeleton, which is simply a load-bearing bracket without power source. Through scientific ergonomic design, it can effectively support heavy objects and reduce the physical consumption of users. It is a kind of power assisted device.


    However, this kind of exoskeleton obviously can''t meet Chen Xin''s requirements, and he doesn''t need to work hard to develop this kind of thing. The country already has something ready-made to use.


    The exoskeleton that Chen Xin wants to develop should be called mechanical exoskeleton or power exoskeleton, which is a kind of mechanical device made of steel frame and can be worn by people. This equipment can provide additional energy for limbs movement.


    This kind of equipment is common in all kinds of sci-fi works, such as 50 pieces of good brother''s armor in StarCraft, Mark''s steel suit in iron man, atongo''s suit in tomorrow''s edge, ugly T Series in radiation, Spartan''s hammer in halo, etc


    These are the exoskeletons that people recognize, or more simply, power armor.


    In fact, strictly speaking, there is not much difference between the two in essence, or the exoskeleton just lacks more solid protective power armor, while power armor is a more comprehensive exoskeleton.


    The concept of this kind of equipment was put forward in the federal government in 1960. After years of research, various related technologies and R & D ideas about exoskeleton have already been proved. What''s left is the hard bone that modern science and technology can''t solve.


    There are two key problems: the first is how to control the exoskeleton in the human-computer interaction mode, and the second is the power source of the exoskeleton.


    The choice of human-computer interaction is not a problem in the development of exoskeleton, but it is not so easy to solve.


    One of the biggest difficulties in the research and development of exoskeleton is the power source.


    In order to solve the problem of power, someone even proposed to make EVA cable powered exoskeleton.


    However, these problems are not very difficult for Chen Xin. Take a few steel pipes, weld an active shelf, arrange a mechanical transmission, connect a battery, and even don''t need hydraulic assistance. Even if a set of original power exoskeleton is made, the subsequent work can be handed over to the system. Chen Xin just needs to upgrade.


    But this is not what Chen Xin wants, or this time, Chen Xin needs to consider more problems and factors.


    Because this exoskeleton protective suit is designed for civilian use, it is mainly provided for construction workers and those who need to leave the shelter to work, so as to provide them with warmth and protection in severe cold and harsh environment, as well as a certain degree of help enhancement.


    Therefore, this exoskeleton protective clothing mainly focuses on protection and warmth, and it doesn''t need to be too strong for power enhancement, and because it is to be mass-produced and put into use, the cost of production and maintenance and the convenience of use should be put in the first place.


    It''s very easy for Chen Xin to make a set of his own. He can only pile survival without considering the cost. Even if he finally piles up a nano armor like mark85, it''s not a problem, but it''s only limited to his own use or small batch supply for people in the shelter.


    Mass production of exoskeleton protective clothing is not a matter of several sets or dozens of sets, or even hundreds of thousands or millions. There are still hundreds of millions of people in China, even one tenth of them need to use exoskeleton protective clothing, which is also tens of millions of sets. If the cost and maintenance are not taken into account, even countries like China can not afford such a huge burden expenses.


    This is the reason why Chen Xin gave up the idea of making full body protective power armor. It''s not that he can''t make it. It''s not that it''s too dangerous and not suitable for civilian use. It''s that there''s no basis for widespread popularization.


    In fact, in Chen Xin''s idea, such a suit of exoskeleton protective clothing can''t even use the miniature isotope thermoelectric battery. It''s enough to install a rechargeable battery that can run for dozens of hours. After all, its main function is to keep warm and protect.


    It''s a good way to keep warm. The pilot''s anti-G suit has ready-made technology. Just add resistance wire like electric blanket to make the protective suit have electric heating function. The only problem is whether the battery can bear it.


    Moreover, according to Chen Xin''s judgment, in the future, this kind of electric heating method will become the main thermal clothing of human beings together with synthetic fiber clothing, because the traditional natural fabrics such as cotton, linen and wool have lost most of the source of raw materials, and even if some of the production capacity can be preserved, it is not for ordinary shelter residents.Therefore, in terms of protective clothing, Chen Xin plans to use one-piece synthetic fiber clothing with electric heating wire to ensure the protective clothing''s resistance to cold.


    After all, this is a relatively low cost, and more convenient way to obtain raw materials, and also more convenient for production.


    In the past, it was difficult to obtain raw materials for duck down and cotton filling to keep warm, so instead of using the filling to keep warm in the past, it was better to directly install electric blanket on the body.


    As long as the thermal performance of the outer structure is good enough, the effect of electric heating is good enough, even if the temperature is dozens of degrees below zero, such a suit of exoskeleton protective clothing is enough to ensure that the wearer will not be frostbitten.


    In addition, a fully covered helmet connected with oxygen supply equipment is enough to resist the harm of various harmful environments to the wearer.


    As for the exoskeleton, it can be relatively simple. It can be based on the relatively mature technology of the existing blind exoskeleton. It can even directly use the blind exoskeleton as the ordinary civil version, and the one with power assisted system can be provided as the upgraded version for the construction workers and other people who need heavy physical labor.


    As for the battery part, Chen Xin plans to develop a large capacity and high-performance battery that can be recharged repeatedly as the power source of the exoskeleton protective suit after completing the miniaturization of isotope thermoelectric battery.


    On the one hand, exoskeleton protective clothing is a common civilian equipment, which does not need long-term power supply. In addition, isotope thermoelectric battery is radioactive element no matter what, so there will be some safety problems when it is used for civilian use.


    On the other hand, due to cost considerations, although the production cost of high-performance battery is not low, it is much lower than that of isotope thermoelectric battery.


    Therefore, after comprehensive consideration of various factors, Chen Xinli also has a concept of how to design the exoskeleton protective clothing.


    Find out a set of old overalls that he got from his father when he was still working, dig out the electric blanket that can''t be used after installing the ground source heat pump, and then go to the warehouse to get the metal materials needed to make exoskeletons. Chen Xin sits in front of the workbench and is ready to make a prototype machine.


    With the old work clothes as the main body and the electric blanket as the material, a set of protective clothing with electric heating function was freshly produced after Chen Xin decided to upgrade.


    Then you need to install the battery, exoskeleton and helmet.


    Among the three batteries, Chen Xin still uses batteries, but this time he is upgrading the batteries to the direction where they can be recharged quickly and repeatedly, rather than making them into highly durable nuclear batteries.


    As for the helmet, Chen Xin only plans to make a simplified cover for the time being. Whether to add other functions in the future is a matter of follow-up research and development. As a prototype, it is enough to be able to seal, provide oxygen and shelter the cold outside.

 Chapter 275

    When a set of samples is made, it''s natural to test them. Because it''s his father''s old work clothes, Chen Xin invites his father to help him with the test.


    However, Chen Xin''s father is not satisfied with the exoskeleton protective suit made by Chen Xin.


    "I can''t walk, I can''t lift my hands, it''s not suitable for work." Chen Xin''s father put on this suit of exoskeleton protective clothing and gave his opinion after moving his body: "moreover, the helmet is too big and inconvenient."


    "So many questions?" Chen Xin was surprised by his father''s comments on the finished product.


    Chen Xin''s father wanted to take the helmet off his head, but because of the joint structure of the exoskeleton, he was unable to bend his arm more than 90 degrees, so Chen Xin had to help take off the helmet.


    Chen Xin''s father, who took off the helmet, said to Chen Xin, "even the helmet needs help. How can you have no problem with this design? Exoskeletons should at least ensure the normal activities of the human body, and should not cause obstacles. "


    "I''ll adjust it. It''s about the joint structure." Chen Xin listens to his father''s advice with an open mind, and he has seen the problems.


    Because of the cost concerns, Chen Xin adopted a relatively simple design for the exoskeleton structure, but it is obvious that this kind of over improvised design greatly reduced the flexibility of the exoskeleton, and even could not meet the actual needs.


    He helped his father remove the exoskeleton from his body. Chen Xin asked his father, "Dad, how about protective clothing?"


    "It''s a little heavy, but it''s OK. It''s like wearing a cotton padded jacket." Chen Xin''s father opened the zipper of the protective clothing and took it off: "it''s a little stuffy to wear, but nothing else is wrong."


    "That seems OK. I''ll try to reduce the weight and adjust the air permeability." Chen Xin took a pen and wrote down what his father said in a notebook.


    After taking off the slightly heavy exoskeleton protective clothing, Chen Xin''s father said to his son, "the problem of clothes is a small matter. The key is the exoskeleton. If you design this thing for people to wear when doing things, you can''t affect the flexibility of the body in the first place.


    To design a thing, you must first make clear what you design it for. All your designs and functions should be designed around this core function. If your design deviates from this core function, then your design itself is wrong. No matter how good the design is, it is also contrary to your original purpose.


    So think about it, what is the purpose of your design, what do you want to do with it, what kind of effect do you want to achieve, and whether your existing design is designed around this core. "


    Chen Xin''s father patted his son on the shoulder and was called to help by Chen Xin''s mother.


    Chen Xin was taught by his father so much that he readjusted his mind and put the whole set of exoskeleton protective clothing on the workbench in order, intending to readjust it.


    One of the key points mentioned by Chen Xin''s father is the joint design of exoskeleton.


    It is not so easy to put the action that is very easy to realize for human skeletal joint on the mechanical exoskeleton. The more flexible the mechanical joint is, the more complex its mechanism will be.


    In order to reduce the cost, Chen Xin''s exoskeleton joints are all connected by swing, which can only swing in a certain degree in one plane. If he wants to move flexibly, he needs multiple joints to cooperate.


    This undoubtedly limits the range of motion and flexibility of exoskeleton joints.


    It''s OK to put it on the lower limbs. After all, most of the time, the human legs just do pendulum movement. They just need to swing back and forth. No one is bored to split the fork.


    But for the upper limb, it''s a bit awkward.


    The upper limb of the human body, that is, the arm, apart from the finger joint of the palm, has four joints: shoulder, elbow, wrist and radius.


    The shoulder joint has the functions of flexion, extension, abduction, internal and external rotation, so the joint head is spherical, which is called spherical joint. With the advantages of spherical joint structure, the shoulder joint can bend 0 ¡ã to 180 ¡ã, extend 0 ¡ã to 50 ¡ã, abduct 0 ¡ã to 180 ¡ã and rotate 0 ¡ã to 90 ¡ã internally and externally, which is one of the most flexible joints in human body, even more flexible than wrist joint.


    Chen Xin''s father said that the inability to lift the arm was largely due to the movement of the exoskeleton in the shoulder joint.


    After all, Chen Xin uses two pendulums to connect the shoulder joint of exoskeleton, one is responsible for swinging back and forth, and the other is responsible for swinging up and down. The combination of the two joints can also make the arm move flexibly within a certain range.


    The flexibility of this part is limited due to the limitation of the structure itself and the need to connect the auxiliary structure.


    The most obvious performance is that the user''s arm can not be raised higher than the shoulder, and there is no way to bend back.


    In addition, the elbow joint of exoskeleton can only do 0-90 ¡ã flexion and extension because of the problem of connection structure. Compared with the normal arm joint 0-150 ¡ã flexion and extension, it has a full 60 ¡ã range of motion, which makes it impossible for users to take off the helmet on their own hands.If we want to improve the flexibility, we can only adjust the connection structure of exoskeleton joint, increase its movement angle, or adopt more complex structure to make it more flexible.


    It''s not impossible to use spherical joints with the same structure as human bones. It''s just that there is a layer of cartilage on the joint surface of human bones and joints. Relying on this layer of cartilage that can be regenerated continuously, the human body can withstand the wear and tear of joints.


    And even so, there are still people because of high-intensity labor, resulting in serious joint wear, joint strain disease.


    For machinery, if it is replaced by spherical joint, mechanical wear will be an unavoidable problem.


    Bearing and lubrication can only be used to reduce friction, or replace after serious wear. However, frequent replacement will undoubtedly increase maintenance costs, which goes against Chen Xin''s original intention to reduce costs.


    Moreover, the use of ordinary metal materials on spherical joints can not support the use of high strength, and the use of wear-resistant high strength materials will increase the cost.


    In addition, there are only more active joints to achieve a more flexible angle of movement, but the complex structure will make maintenance extremely troublesome, which makes Chen Xin suddenly fall into a dead cycle.

 Chapter 276

    Although Chen Xin was puzzled by the problem of exoskeleton mechanical structure design, it was not difficult to solve the problem.


    The orthodox solution is to send this problem to the national scientific research institutions, and let the experts of relevant disciplines to improve the design.


    After all, it''s not very complicated or highly technical. Joint design in exoskeleton development is really a big problem, but it''s not an unsolvable problem.


    The country already has mature experience in exoskeleton design and related research and development, so it is not a big problem to apply it.


    The more convenient way is to upgrade the exoskeleton with the system. Anyway, Chen Xin has to use the system upgrade function to solve the energy problem of the exoskeleton. It''s just a convenient thing to optimize the mechanical structure of the exoskeleton.


    This time, however, Chen Xin did not continue to use the upgrade function of the system to optimize the structure of the exoskeleton after completing the upgrade of exoskeleton energy, that is, high-performance rechargeable battery.


    Although this is a very simple thing, in Chen Xin''s opinion, relying on the convenience brought by the system upgrade all the time will make him more and more lazy, and his thinking will become more and more passive.


    It''s like playing a game with the modifier turned on. After the modifier is changed to kill with one strike, you won''t think about how an enemy should be defeated, and what attributes and weaknesses the enemy has, because for you, it''s all about touching.


    The original formidable enemy has become a porcelain doll that can be knocked down at one touch. The game itself has lost the challenge and a considerable part of the fun for you to immerse yourself in.


    As for Chen Xin, he also hopes to solve problems through his own ability, rather than relying on the system for everything.


    After all, it''s just the joint structure of the mechanical exoskeleton, which can be solved by his own ability. If he really can''t solve the problem, Chen Xin certainly won''t be stingy with the use of the system upgrade ability.


    But now, he still wants to try to solve the problem himself.


    In the final analysis, the system is only providing an upgrade scheme according to Chen Xin''s idea. If Chen Xin has no idea in his mind, even the system is difficult to work.


    Therefore, it is necessary for Chen Xin not to rely on the system, but to rely on himself to solve problems and exercise his thinking ability.


    In the final analysis, this problem is not difficult to solve. Either wear-resistant materials are used to directly connect the spherical joints, or more flexible structural design is adopted. Chen Xin has the ability to solve both problems.


    However, while Chen Xin is seriously studying the mechanical structure of the exoskeleton and thinking about how to solve the problem, Mo Qingyan finds him.


    "Ah Xin, the vegetables in the greenhouse can be harvested this month. Is it the same as before, trading with the Swat?" In the face of Chen Xin, Mo Qingyan''s look was a little cold, and she didn''t even call him his nickname as before.


    In this regard, although Chen Xin understood the reason why Mo Qingyan was indifferent to her, he didn''t say anything more. He just nodded and replied, "it''s better to follow the previous process."


    "But the output of this month has at least doubled that of last month. The special police may not be able to eat so many vegetables." Although Mo Qingyan is a little indifferent to Chen Xin, she is not affected in dealing with specific matters.


    Chen Xin also reacted to Mo Qingyan''s words. Before he left, he upgraded the planting greenhouse from 200 square meters to 600 square meters. Last month, because he had just finished the upgrade, the hydroponic planting plate of the six layer three-dimensional structure of the planting greenhouse had two layers of rice, one layer of fruit, one layer of vegetables, and three layers of vacant space, so it was difficult to produce rice There has been no increase in quantity.


    But last month, after handing over the output of that month to the special police force to repay Chen Xin''s material debt, Mo Qingyan planted crops on the empty three-layer planting plate in the greenhouse, which led to a direct tripling of vegetable production this month.


    When Chen Xin left, there were a quarter of carrots, a quarter of cabbages, a quarter of lettuce, and a quarter of strawberries in the first floor. There was no plan for the vacant three floors.


    After a harvest, Mo Qingyan adjusted the four layer planting plate. The carrots and strawberries did not move, but planted the other two crops with longer growth cycle. At the same time, she moved the planting of cabbage and lettuce to the two vacant layers, and directly planted one layer, and planted pepper on the last layer.


    For the people of Hunan Province, they don''t get hot peppers. They really don''t smell good at anything.


    Before that, there was no such condition, so I didn''t demand it. After all, I don''t have enough to eat. Who cares what I eat?


    But here in Chen Xin, Mo Qingyan obviously doesn''t need to think about whether she has enough to eat. In addition, she saw that there were pepper seeds, so she planted one layer directly.


    Chen Xin knew this when he came back, but he didn''t have any opinions on it. Although Mo Qingyan''s planting plan deviated from his expectation, it was not unacceptable. After all, although Chen Xin is from Anhui Province, he has lived in Hunan Province for decades, and he also likes spicy food.Moreover, pepper, as an indispensable food for Hunan people, can be sold in hard currency even if they can''t eat it. Chen Xin doesn''t want to rot these things.


    Of course, all of these can be put into the future. What Chen Xin has to face now is that the yield of vegetables has tripled, which is equivalent to four times the original yield.


    There is no doubt whether the special police team can eat so many vegetables or not. Such a big special police team can''t eat so many vegetables. Besides, there are other departments of the whole city police station and the refuge of the whole city police station. It''s no problem that Chen Xin''s output is consumed.


    It''s just that Chen Xin can''t give away so many vegetables for nothing. What to change has become a problem Chen Xin needs to think about.


    For Chen Xin now, it''s no problem that he needs any materials after cooperating with the state. When he was making Qin Lan''s second artificial limb, Chen Xin wanted to use carbon fiber materials, and the scientific research institution he cooperated with sent them to him without saying a word, so Chen Xin really has no shortage of materials.


    In terms of basic materials, Chen Xin, who has entered the stage of food and clothing after the overall upgrade of the refuge, is not very keen on this.


    In Chen Xin''s opinion, the scale of the refuge is enough now, and there is no need to expand it. Even if it is upgraded, it will gradually improve the level of science and technology and comfort, so he is not interested in building materials and metal materials.


    What''s more, four times of the original output will be able to exchange more materials. If you directly exchange construction materials, you have to fill the warehouse.


    So what should I exchange? Or don''t you give all these vegetables to the SWAT team and let Li Yulong sell some of them?

 Chapter 277

    Chen Xin didn''t worry too much about the surge of vegetable production. As long as the vegetables are not harvested, they will not be bad if they are planted on hydroponic plates all the time, but the taste will get old.


    But it can''t be left alone. While thinking about how to improve the exoskeleton, Chen Xin is also thinking about how to deal with the surge of vegetable production.


    Although the number of people in the shelter is much more than before, and the consumption is also increased, compared with the surge of production, the increased consumption is really not worth mentioning.


    After all, it''s vegetables that add up to nearly two or three thousand kilograms. According to the agreement between Chen Xin and the special police force, so many vegetables need to be traded to them for a quarter. Eight people in the shelter reserve about one tenth of their share. At present, some chickens and fish can be consumed, but more than half of them are still left. At least more than 1500 kilograms of vegetables need to be considered.


    More than 1500 kilograms of vegetables, if it is before the disaster, dragged to the vegetable market may be sold out in a day or two, it is not a matter at all.


    Now, after the disaster, although it is also a very tight supply, if Chen Xin is willing to sell more, people want to buy it, but Chen Xin doesn''t want to exchange these vegetables for a lot of things that he can''t use.


    But Chen Xin still wants to get rid of the more than 1000 kilograms of vegetables. Especially when he brings back sweet potato seedlings from his hometown, he needs to set aside a layer of planting plate in the greenhouse to plant them. Chen Xin can''t let these vegetables still occupy the planting plate.


    What''s more, he has to find a way out for the extra output every month after the planting area in his greenhouse has expanded and the output has doubled.


    The trading volume of the special police force can be expanded a little, but considering what can be exchanged, the potential of this part of trading share is limited. Chen Xin exchanges more shelter rations and living materials every month at most.


    He can get this part of things from other people, especially when Chen Xin is cooperating with the state. Other things may be a little difficult, but even if Chen Xin asks for food and living materials, he can get them.


    So after thinking about the pros and cons, Chen Xin decided to let Li Yulong sell the rest of the deal in his market, except for expanding the fixed deal with the SWAT team.


    On the one hand, this is a kind of support for Li Yulong''s trading market, adding fresh vegetables as marketable goods, which can help the trading market better open up the situation.


    On the other hand, it can also be regarded as an investment. Since Chen Xin doesn''t know what to exchange for, it''s better to use these vegetables as an investment to help Li Yulong. In this way, he can get more returns.


    And this is also to find a way to consume the monthly increase of vegetable production, so as not to find a market for the increased vegetable production.


    After learning about Chen Xin''s decision, Mo Qingyan didn''t express any opinions on this matter. She just confirmed to him the harvest time of crops in the greenhouse, so she didn''t say anything more.


    In the face of Mo Qingyan''s indifference, Chen Xin feels helpless for a while. But with his parents around, Chen Xin is really not good at dealing with this kind of emotional problem. In addition, he really treats Mo Qingyan as a friend all the time, and does not develop the idea of a relationship beyond friendship. He can only put this matter on hold for the time being and deal with it coldly.


    After dealing with these things, Chen Xin continued to put his energy into the improvement of the exoskeleton mechanical structure. After all, this is what he is most concerned about right now.


    For the lack of joint flexibility of exoskeleton, Chen Xin first adjusted the movable range of each joint and increased the movable angle of each pendulum connection.


    After the adjustment, the flexibility has been improved to a certain extent. At least now Chen Xin can take off the helmet on his head without wearing an exoskeleton.


    But the movable range of the shoulder joint is still insufficient, the arm can only be lifted flat, unable to extend backward and upward.


    This is mainly due to the limitation of the structure itself and the need to install a hydraulic telescopic rod for power assistance.


    After all, joints, as the main moving parts, are also the main power points. While adjusting the flexibility of joints, Chen Xin must also consider the problem of power assisted mechanism.


    Elbow joint adjustment is relatively easy, because the elbow angle itself is not too big, through the hydraulic telescopic rod length adjustment, it can make do.


    But the adjustment of shoulder joint is not so simple.


    There are two active joints in the shoulder joint, one of which is an axis perpendicular to the back, which is located in the position of the human scapula. The structure of the whole exoskeleton arm part is connected to this axis, thus connecting with the main body of the exoskeleton, which is also the main joint of the arm part that can swing forward and backward.


    The motion of this joint is that the shaft itself is fixed, and other structures connected to the shaft rotate around the shaft. Limited by the structure itself, and the swing range of the arm is not too large in actual use, the shaft can only swing 0 ¡ã to 70 ¡ã in a limited way, and it can reach 90 ¡ã after adjustment. Although it is not very flexible in use, it is enough.The rest is a shoulder joint, which is a typical pendulum connection. It is responsible for connecting the axial joint structure of the back and the main part of the arm. It is the most important activity joint of the whole exoskeleton upper limb, and also the joint with the largest range of activity.


    In theory, these two joints can make the arm swing back and forth, but because of structural problems, the swing range of the shoulder joint pendulum is only 0 ¡ã to 120 ¡ã now. This swing range can''t even respect the French military salute. It can only respect the German military salute during World War II.


    To improve this joint, other connection methods will only make the structure more complex. Although the flexibility is increased, the installation of the booster becomes troublesome.


    Chen Xin has considered using universal joint, magnetic suction joint and spherical joint of air bearing as the connection method, but the effect of the samples is not ideal after trial, which will not only make the structure of exoskeleton more complex, but also interfere with the assist structure. In fact, the flexibility that can be improved is limited.


    This makes Chen Xin very scratching his head.


    Chen Xin can''t really think of a way to improve it. After a bout of irritability, Chen Xin chooses to leave the table full of useless plans and decides to play a game to relax. By the way, he also wants to find inspiration from science fiction games.


    After turning on the game console, Chen Xin holds the handle to pull the game. Halo and mass effect have little reference value. They are power armor. The structure of the whole body is totally different from the exoskeleton structure of just two iron bars.


    It is the exoskeleton in call of duty 11 that makes Chen Xin feel bright in front of his eyes, but after careful observation, he can only learn from it in part.


    In call of duty 11, the exoskeleton back is fixed, but the shoulder directly uses the same spherical joint as the human body structure, and two spherical joints are connected, providing enough flexibility for the shoulder.


    Of course, this kind of structure can be used, but the friction surface of the spherical joint is too large, and if we want to ensure enough flexibility, we can not use the fixed structure. We can only wrap it with flexible materials or simply make it into magnetic absorbers like human joints.


    Of course, rubber is the first choice for flexible materials, but now the rubber can only be synthesized in industry, and it is easy to become brittle and lose its original effect in the low temperature environment of minus tens of degrees. In the case of magnetic absorption, how to ensure the stability of the structure, not to be disjointed in use, and the wear of the magnetic absorption surface are all problems to be considered.


    And the most important thing is that there''s no problem with how to design the game. There''s no need to consider whether science and technology can do it or whether the structure is really reasonable. Even if it''s designed as a magnetic suspension joint, others will only say that technology is awesome.


    But in reality, Chen Xin has to consider more, especially when he is aiming at saving cost to consider the design of structure, it is even more impossible to adopt too complex or too high cost structure.


    So thinking about it, Chen Xin ruled out the connection of spherical joints.


    However, it is still very difficult to solve the problem.


    Fortunately, the mechanical structure of several games still gave Chen Xin a lot of reference. After careful thinking and comparison, Chen Xin decided to add a new joint on the basis of the original two shoulder joints, so as to increase flexibility.


    The back shaft joint remains unchanged, and the original pendulum connection of the shoulder part is changed into a disc-shaped connection structure, which integrates the assist structure and the joint. The rotation angle of 0 ¡ã to 270 ¡ã is achieved by the motor driving the internal structure of the disc.


    At the same time, at the lower part of the disc structure, there is a rotation joint whose rotation axis is perpendicular to the rotation axis of the disc, so as to ensure the flexible rotation of the arm.


    After this adjustment, we finally solved the problem of the flexibility of the exoskeleton upper limb, so that the arm can get help while ensuring enough flexibility.


    After solving this problem, the biggest problem for the whole set of exoskeleton protective clothing has been solved. As for the problem of high-performance batteries and the helmet that Chen Xin''s father reflected is too big, this is a good solution.


    According to his father''s suggestion, Chen Xin reduced the original huge helmet from the original helmet like a spacesuit to a motorcycle like helmet that completely fits the head with only partially transparent eyes and connected with a breathing mask. Finally, Chen Xin made a set of test samples of exoskeleton protective clothing.


    This time, he put on the experimental exoskeleton protective suit himself. Without other people''s help, Chen Xin spent about five minutes to put on the whole exoskeleton protective suit.


    Although it''s a bit cumbersome, Chen Xin thinks that it''s an acceptable level. After all, it''s just a civilian type, and there''s no need to consider the need for quick wear and take off. As long as you can wear and take off by yourself, and it won''t take too much time and effort.


    After wearing the exoskeleton protective suit, Chen Xin turned on the power and walked into the elevator, intending to go outside to test the effect of the exoskeleton protective suit.

 Chapter 278

    Chen Xin walked out of the shelter in exoskeleton protective clothing, while Han Ping followed him warily, looking around with his eyes to prevent possible dangers.


    Originally saw Chen Xin want to go out to test exoskeleton protective clothing, Han Ping is to want him to test for Chen Xin, let Chen Xin stay in the shelter.


    After all, Han Ping was introduced to Chen Xin by his second uncle to work as a bodyguard and driver for him. In addition, since Chen Xin came back, he has established a cooperative relationship with the state. Naturally, Han Ping can understand the importance of Chen Xin. During this period, people from the army even came to him to protect Chen Xin carefully.


    This naturally makes Han Ping pay special attention to Chen Xin''s safety. Fortunately, Chen seldom leaves the shelter, and his shelter is as strong as a blockhouse. Even if he wants to go out, he will drive an armored car, so Han Ping doesn''t need to worry about Chen Xin''s safety.


    But this time Chen Xin wanted to test the exoskeleton protective clothing, and he really walked out of the shelter, which inevitably made Han Ping nervous, even more nervous than when he first performed a task as a soldier.


    Fortunately, Chen Xin didn''t go far. He just tested at the gate of the shelter.


    Chen Xin, who just came out of the shelter, didn''t turn on the heating function of the exoskeleton protective suit. He needed to test its resistance to low temperature and cold under normal conditions.


    The test results were somewhat unsatisfactory. The instrument Chen Xin specially installed on his arm showed that the ambient temperature was - 37 ¡æ. After standing in the snow for only a short time, he felt that his legs were cold and almost unconscious, and his body was cold. Even the surface of his clothes was frozen.


    This makes Chen Xin quickly turn on the heating function of the clothes.


    Soon the temperature rose, and the hot air came out from the electric wires all over Chen Xin''s body. It soon dispelled the cold air in Chen Xin''s body, and even his cold and unconscious feet recovered in a burst of numbness.


    Feeling the temperature rising, Chen Xin moved his hands and feet again, ready to take a look at the temperature displayed by the instrument on his hand. However, he reflected that the instrument on his hand can only display the ambient temperature, and has no function of monitoring the temperature inside the clothes.


    This made Chen Xin want to clap his forehead, but when he raised his hand to the middle, the idea was gone, because the reaction speed of exoskeleton was not so fast, and his hand was only raised to the middle.


    Looking at his half lifted arm, Chen Xin knows that there are still many things to be modified in this exoskeleton protective suit. For example, the status display just thought of should not only display the ambient temperature and internal temperature, but also display the oxygen and battery power, so that users can know their own status at any time.


    At the same time, Chen Xin also found that he was missing one of the most important components, which was the phone. Just now he wanted to shout to Han Ping and ask him to record for him, but he found that the voice could not be transmitted. That''s why he found out the problem.


    The sealed helmet does have good performance in wind protection, heat preservation and oxygen supply, but after being isolated from the inside and outside, there is no way to transmit the voice without using the phone.


    This is inevitably inconvenient.


    However, these are details. Chen Xin doesn''t deal with them. He hands over the prototype to the state, and the R & D Department of the state will fill in these details, but he doesn''t have to worry too much.


    What we really need to test and consider is the flexibility of the exoskeleton protective clothing and the heat preservation and heating functions that have been tested just now.


    The thermal performance can only be said to be unsatisfactory. The suit itself is not designed for cold protection, so the cold protection effect can only be reluctantly. The heating function is fairly good. After a short meeting, Chen Xin feels warm all over.


    So he did a set of radio Gymnastics in the snow, which was specious and basically forgotten.


    However, although he did it in a mess, Chen Xin didn''t really want to do radio gymnastics. He was just testing the flexibility of the exoskeleton in this way.


    After all, to say physical activity, radio gymnastics is absolutely second to none, the effect is good.


    After a messy set of broadcast gymnastics, Chen Xin finally has a complete concept of the flexibility of the improved exoskeleton. Generally speaking, all aspects are very good. The upper limb can be lifted and put down freely with both hands, stretched forward and backward, and bent at will. Basically, it has met the needs of arm movement under normal circumstances.


    It''s just that after all, it adopts the operation mode of force feedback. It''s still a little slow in response sensitivity. It has a sense of delay, but it doesn''t affect the use. It''s just a little slower when it''s used.


    After all, it''s just a set of exoskeleton for civilian use. It''s mainly used for moving bricks on construction sites, not on the battlefield. It doesn''t need to be so sensitive.


    After testing the sensitivity of the exoskeleton, Chen Xin even completed the test, so he turned and went to the gate of the refuge.


    When Han Ping saw that Chen Xin had finished the test, he was also quietly relieved, but he did not relax his vigilance. He still looked around carefully to avoid possible danger.


    Just as they were about to return to the shelter, a little light suddenly moved towards them from a distance."Mr. Chen, it seems to be coming this way." Han Ping said to Chen Xin, and asked him to go to the shelter first: "for safety''s sake, you''d better go first."


    Chen Xin didn''t insist. He nodded and walked into the shelter. Although he was wearing this suit of exoskeleton protective clothing, it was warm on the outside and cold on the inside. After the ice on the surface melted, the water vapor had wet the clothes, especially the trouser legs.


    This makes Chen Xin find another area that can be improved, that is, the clothes must be waterproof, otherwise it doesn''t matter if they are worn in dry places. If the ambient humidity is a little higher, they may become ice shells.


    However, in addition to water-proof, de icing is also something that needs to be paid attention to. Otherwise, the joints of the exoskeleton are unable to move due to freezing, or the circuit is short circuited due to freezing and water ingress, but there will be a lot of problems.


    So after returning to the shelter, Chen Xin took off his exoskeleton protective suit.


    When taking off, Chen Xin also found that this suit needs to add a temperature regulating function. It''s really OK to heat it all the time outside. Anyway, the temperature outside is low enough. It''s just right to keep warm when it''s always on.


    But in the room, if there are only two options of switch, and there is no option to adjust the heating temperature according to the ambient temperature, the clothes are rather chicken ribs.


    Moreover, the temperature control function is not complicated. The temperature control technology is just a matter of reforming the control switch.


    The exoskeleton protective clothing was put on the workbench. Chen Xin took out his notebook and recorded what he had just thought. He was ready to improve step by step.

 Chapter 279

    Outside the shelter, a truck accurately stops at the gate of Chen Xin''s shelter.


    From the car down is Qin Lan''s old boss Li Tou, since Qin LAN injured left the SWAT team, and Chen Xin''s side of the contact is transferred to him.


    And behind Li Tou came Ding Ning. But for some reason, the little girl''s face was smelly. It seemed that she was angry with someone.


    Because there was contact before arriving at Chen Xin''s shelter, when the car stopped at the gate of the shelter, Han Ping had just opened the door again, so Ding Ning and Li Tou got out of the car and went directly into Chen Xin''s shelter.


    "What about the ingredients?" Seeing Han Ping coming up, Ding Ning asked him directly, "who are you? I haven''t seen you before! "


    "My name is Han Ping. I''m Mr. Chen''s driver. My brother and I followed him from his hometown in Anhui Province." Although Han Ping didn''t know who Ding Ning was, he politely introduced himself and said, "Mr. Chen is downstairs. I don''t know what''s the matter with you two?"


    Han Ping said, but did not directly let the two people into the shelter, but waiting for others to come out to pick them up.


    He doesn''t know the two people in front of him. Although the communication sent by the other party said it was from the special police team, he asked Chen Xin and got the answer that he could open the door, but he was still very alert and didn''t put Ding Ning and Li Tou in directly.


    However, after receiving his notice, Qin Lan said that he would come out to meet someone, so he didn''t have much to do, just stopped them at the door, waiting for Qin LAN to come up.


    Qin LAN came up quickly, and did not let Ding Ning and Li Tou wait for a long time to appear in front of them.


    "Sister LAN!" "Ah LAN!" Ding Ning and Li Tou greet Qin LAN together.


    Ding Ning noticed Qin Lan''s right hand, ran to her immediately, held Qin Lan''s right hand, asked her: "sister LAN, your right hand is cured?"


    However, when Ding Ning holds Qin Lan''s right hand, he only feels the hardness, and immediately understands that Qin Lan''s right hand is not cured, but a prosthetic limb.


    "Well, ah Xin made me a prosthetic limb, which is basically the same as before." Qin LAN smiles at Ding Ning. Now she doesn''t care much about her right hand. At the same time, she looks at Li Tou: "long time no see, captain."


    Seeing Qin Lan''s present appearance, Li Tou was relieved. He said with a smile, "it''s a long time since I saw you. I''m relieved to see that you''re ok now."


    Before Qin LAN broke her hand, Li Tou went to see her when she was treated in the hospital, but at that time Qin Lan''s face was full of death ambition, and the whole person was lifeless, as if she was going to die soon. How could she be so smiling and full of vitality now.


    "It''s worrying you, captain." Qin LAN is also a little embarrassed, before his appearance of dying, now it seems that it is not worth it, but also let the people who care about themselves worry too much.


    Ding Ning doesn''t seem to have so much thought. Seeing that Qin Lan''s right hand is as flexible as she said before, she said happily: "it seems that the food material is quite capable. It''s actually cured elder sister Lan''s hand."


    Qin LAN didn''t care much about Ding Ning''s words, but after a smile, she looked at Li Tou and asked him, "Captain, what are you doing here today?"


    "Well, it''s the same as before. It used to be Xiao Qin. You are in charge of this. Now team Ding has handed it over to me. " Li Tou nodded and explained why they came.


    "Well, I''ll take you down. Ah Xin transformed the greenhouse before, and the vegetable yield is a little high this month." Qin LAN chuckled at them. Then he took them through the corridor, into the elevator and came to the lower floor of the shelter.


    Walking out of the elevator, Ding Ning looks around curiously. This is the first time that Chen Xin has come here after upgrading the whole refuge. She is surprised and curious.


    "This place has changed a lot. It seems that the ingredients are still quite tossable." Ding Ning saw the clean and comfortable shelter inside, and his heart was sour.


    Previously, Mo Qingyan and Mo Qingxin were invited by Chen Xin to look after the house for him, while Ding Ning and Qin LAN lived in Mo Qingyan''s refuge. Although the conditions there were not bad, there was a gap compared with Chen Xin''s refuge after the overall upgrade.


    At least Mo Qingyan''s home is not as comfortable as Chen Xin''s. she can''t put on her heavy clothes and wants to take off her coat.


    "Xiao Ding, Captain Li, why are you two here today? Is it for the exchange of goods and materials? " Chen Xin raised his head in front of the workbench, looked at them and said hello to them.


    Ding Ning and Li Tou came to Chen Xin. Before Li Tou spoke to Chen Xin, Ding Ning saw Chen Xin''s exoskeleton protective clothing on the workbench and said in surprise: "is this exoskeleton? You made the ingredients yourself? "


    "I did it myself, but I haven''t finished it yet. Many places need to be improved." Chen Xin did not hide the fact that he was able to make exoskeletons.


    "Wow, you are really good! I thought you would be great enough to write a novel, but I didn''t expect you to be an iron man! " While praising Chen Xin, Ding Ning put out his hand and patted him twice on the shoulder: "when can I have one too?""When I''ve finished it, I''m sure you''ll have it." Chen Xin did not mean a set of protective clothing, readily agreed to come down.


    When Ding Ning finished his exoskeleton painting and color matching, Li Toucai said: "Mr. Chen, we are here to get the vegetables you promised this month. Before, you advanced three months'' trading share from our special police team. This month is just the last month."


    Chen Xin had no objection to this and nodded directly, but he still said to Li Tou: "of course, there is no problem with the share promised before. However, when I went to rebuild the shelter, I expanded the greenhouse. This month''s vegetable production has quadrupled. In the future, I will be able to provide more vegetables. This month, I will have to add a few hundred kilograms of vegetables Let''s exchange our share for living materials and rations. "


    "It''s no problem, but we didn''t bring supplies today. We can''t bring them tomorrow." Just now I heard Qin LAN talk about it. Naturally, I''m ready.


    Chen Xin nodded. He was not afraid that Li Tou didn''t deliver the goods. He was greedy of his vegetables: "OK, just so many vegetables need time to harvest, so please come back tomorrow."

 Chapter 280

    In the early morning, when Chen Xin finished washing and took the elevator to the observation room on the top of the shelter, Han Ping and Han Ze were cooking a pot of thick hot soup around the stove. The smell of food wafted in the air, and the heat from the stove also slightly dispelled the cold in the room.


    "Good morning, Han Ping, Han Ze. Did you sleep cold last night?" Chen Xin felt the temperature in the room for a moment and asked the Han brothers, who were wearing temporary exoskeleton protective clothing.


    "Mr. Chen." When Han Ping saw Chen Xin come in, he quickly pulled his younger brother aside and stood up to greet Chen Xin: "it''s OK. I can stand it in the room at night, but I have to turn on the heating of my clothes when I watch the night, otherwise I can''t stand it."


    After hearing Han Ping say so, Chen Xin motioned for them to sit down. Then he took a look at the observation window which has been blocked by the glass in the observation room. He shook his head and said helplessly: "it''s good if you can stand it. No, you can go to sleep at night. It''s too cold for anyone to come here in this bad weather. "


    However, Han Ping still shook his head and said: "the more such weather is, the more vigilant we should be. People who can come out of this weather are either ferocious or can''t live. They are very dangerous and must be vigilant."


    Facing Han Ping''s attitude, Chen Xin can''t say anything about him, but he complains about the snowstorm without warning.


    Not long after Li Tou and Ding Ning had been here before, there was a blizzard that night, and the temperature dropped sharply again. The temperature dropped from more than 30 degrees below zero, which was tolerable, to more than 70 degrees below zero, accompanied by a strong wind that could overturn an ordinary car.


    The arrival of the blizzard without any signs, as if it is blowing up in an instant, before people have no reaction, it has swept everything.


    Chen Xin can understand the appearance of this kind of weather. After losing the protection of vegetation and the regulation of atmospheric circulation, the weather system on the whole earth''s surface has completely collapsed. The strong wind has lost its blocking and become more and more violent. The appearance of extreme weather is only one of the effects of the collapse of the weather system.


    In the past, the cold wave in winter will cause a large-scale cooling of the whole country. Now that the weather system has collapsed, the cold brought by this snowstorm will also affect many places. What is different from the past is that once the temperature drops, it is difficult to recover.


    Because the sun, the main source of heat on the surface of blue stars, has been blocked by dust, it is still very difficult for the temperature to recover even if the snowstorm dissipates.


    At this time, the strong wind of more than 12 levels outside the shelter is whistling, rolling up countless goose feather and heavy snow. If there is still the sun, we can see the vast white scene of heaven and earth.


    However, the snowflakes floating in the sky at this time are not ice crystals, but carbon dioxide snow formed by the liquefaction and condensation of carbon dioxide in the air at low temperature, which is commonly known as dry ice.


    The extreme low temperature has obviously broken through the limit of most buildings to resist the cold. Even Chen Xin''s upgraded shelter can''t stand it, so Chen Xin has to turn on the heating system in the shelter to the maximum power to ensure the indoor temperature and the survival of indoor plants.


    This also makes Chen Xin realize that the ground source heat pump as a heating equipment has a problem, it is affected by the formation temperature, and temperature limit.


    Although there is no problem at present because his shelter is deep underground, if the snowstorm continues, the temperature will not rise again. The deep layer may not have any effect, but the temperature in the shallow layer will certainly decrease.


    This will undoubtedly affect the ground source heat pump equipment, which mainly depends on the temperature of the shallow layer to obtain heat, and reduce the heating effect.


    So if the temperature continues to drop, Chen Xin must consider using other heating methods in the shelter.


    Now, the temperature in the upper observation room on the earth''s surface is as low as 20 degrees below zero, which is the result of Han Ping and Han Ze''s stove being on all the time.


    It was because of the low temperature that Chen Xin wanted the two brothers to go to the lower level of the shelter. It was too cold up there. He was worried that the two brothers could not bear it.


    But Han Ping insists on staying on it, and has been doing night watch work with his younger brother.


    Chen Xin, who can''t be persuaded, can only let Han Ping and his younger brother stay at the top of the shelter, but for the sake of safety, Chen Xin has prepared a stove and two sets of emergency protective clothing for them to avoid frostbite and damage in the low temperature environment.


    With protective clothing, Han Ping and Han Ze actually feel that the temperature is tolerable. After all, they are wrapped in an electric blanket. In addition, there is a stove where they can cook hot food at any time to supplement their body heat. Apart from being a little hard at night, they are all OK.


    However, Han Ping was still worried and asked Chen Xin, "Mr. Chen, our conditions here are so good and it''s so cold. Is it colder in other places?"


    "Other places? If you don''t do a good job in keeping warm and cold, I''m afraid it''s not just a colder problem, it''s going to freeze to death. " Asked this question by Han Ping, Chen Xin shakes his head.The temperature of more than - 40 degrees below zero can still be met in the north of Yanguo, but the temperature of more than - 70 degrees below zero is already very extreme.


    In this kind of temperature, the scene that the helicopter flying in the sky directly freezes down in the movie the day after tomorrow will really appear.


    Even if there are buildings that can withstand the cold wind, if there is no heat source, the temperature drop is enough to freeze all life.


    The urban area relies on coal-fired boilers for heating, which should still work normally in this weather. However, most of the shelters in the urban area are not deep underground, and most of the cold proof and heat preservation were temporarily renovated three months before the disaster, which makes Chen Xin very worried about the situation in the urban area.


    But in this environment, even Chen Xin does not dare to go out. The snowstorm outside is enough to put any vehicle into a desperate situation. Even his modified tracked RV is difficult to guarantee no accident in this environment.


    Maybe only the heavy-duty vehicles in wandering earth can cope with such bad weather?


    Chen Xin thinks so in his heart, and his attitude of becoming more comfortable because of better living conditions has become nervous again, feeling the crisis of survival.


    Although Chen Xin is able to live without food and clothing, it is not that he really has no survival crisis.

 Chapter 281

    Seeing that Han Ping and Han Ze didn''t have any big problems, Chen Xin chatted with them again, and then returned to the lower level of the refuge.


    Compared with the observation room on the upper floor, where even if the furnace is turned on, the temperature is only 20 degrees below zero. After Chen Xin has run the ground source heat pump at full power, the temperature on the lower floor of the shelter is still about 10 degrees.


    Although a human body will feel cold, it is not too cold.


    However, the temperature is OK for the human body, but it is still a little low for the crops in the greenhouse, especially for Chen Xin who is still breeding.


    "Ah Xin, the temperature in the greenhouse is still a little low. I''m worried that there may be problems in seedling raising. Do you want to use a seedling box?" Seeing Chen Xin coming back, Mo Qingyan finds him for the first time and asks him.


    Hearing Mo Qingyan''s inquiry, Chen Xin thought for a moment and said to her, "try to cover the seeds with a wet cloth. It shouldn''t be a big problem to ensure that the temperature is above 20 ¡æ. If the temperature is still not enough, you can use a seedling box."


    "OK, I''ll try first." Mo Qingyan nodded.


    There are many effects of low temperature, and the effect on Seed Germination in greenhouse is only one of them.


    "Long Niang, have you harvested all the mature vegetables in the greenhouse before?" Chen Xin thought of the vegetables that had not been harvested when they came to Li Tou and asked Mo Qingyan.


    "You don''t have to worry about that. I''ve picked all the vegetables that can be harvested before cooling down and sent them to the warehouse above." With that, Mo Qingyan seems to be afraid that Chen Xin is not sure about the stored vegetables. She continues to add: "as for the warehouse above, it''s the same as the frozen warehouse now. There''s no need to worry about the damage of vegetables on it."


    "And be careful not to freeze out." Chen Xin thought of the low temperature above, which was more than 20 degrees below zero, and didn''t worry about what Mo Qingyan said.


    At such a low temperature, all vegetables will be frozen quickly after they are put in, just like the quick freezing mode in the refrigerator, so there is no need to worry about the damage.


    "But there are still a lot of vegetables. It''s no problem to put them in the warehouse for the time being, but it''s better to ask the special police to send someone to pull them away as soon as possible." Mo Qingyan is obviously worried. If that batch of vegetables can''t be taken away in a short time, and she is planting new seeds and waiting for the new vegetables to mature next month, it will explode.


    Although this kind of problem sounds a little worrisome, under the current situation, whether the Blizzard can stop within a month is really a problem.


    Chen Xin obviously also considered this problem, but he was not optimistic: "I''m afraid we can''t get here in a short time. In this snowstorm weather, it''s all death to drive out."


    "Is it serious outside?" When Chen Xin and Mo Qingyan say these things, Qin Lan also comes over.


    She was checking the chickens just now. Although the temperature of more than ten degrees is not low for chickens, the chicks still have the risk of premature death in the face of this low temperature. That''s why Qin LAN went to check the room where the chicken coop is, so as to avoid freezing the chicks to death.


    Chen Xin nodded with a heavy face: "without the forest, the wind speed on the surface has exceeded level 12, and the temperature has dropped below - 70 ¡æ. If there is no protective equipment, it will freeze to death within half an hour after going out, and it is very likely that the front foot will go out, and the back foot will be blown away by the wind."


    -A low temperature of 70 ¡æ and a gale of force 12 or above are totally inconceivable to ordinary people. Such a bad climate would only appear in the Antarctic continent, and even a low temperature below - 70 ¡æ would only appear in some places of the Antarctic continent.


    For modern humans, such a low temperature is unimaginable in life before the disaster.


    "Seventy below zero? Oh, my God Qin LAN can''t help exclaiming. She can''t help asking Chen Xin, "can the shelter in the city bear such a low temperature?"


    For this problem, Chen Xin shook his head and looked a little heavy: "I''m afraid it''s choking. Their thermal insulation measures may not be able to withstand the severe cold, and the efficiency of the heating equipment of coal-fired boilers is also limited. If they can guarantee the fuel supply, they can still stick to it. But... "


    Chen Xin''s words did not finish, but Qin LAN and Mo Qingyan understood his meaning.


    In such extreme weather, I am afraid that even the train is difficult to continue to transport, and the city is likely to face the shortage of coal again.


    The last time there was a shortage of coal in the urban area, Qin LAN and Mo Qingyan experienced it personally. They knew clearly what terrible consequences would be if the coal supply in the city was interrupted.


    This makes Qin LAN nervous. She reaches for Chen Xin''s arm and asks him, "is there any way to solve this problem?"


    Chen Xin shook his head bitterly. Although there is a system, he can create some black technology equipment to make his refuge cope with the cold winter without problems, but it is really difficult for him to solve the problems of the whole city.


    See Chen Xin also have no way, Qin Lan also understand that he is forced, only a face of loss released Chen Xin''s arm.


    Seeing Qin Lan''s loss, Chen Xin comforted her: "maybe the situation is not as bad as you think. After what happened last time, the city government must have made an emergency plan and reserved emergency coal. They can deal with this kind of crisis."Of course, Qin LAN can hear that Chen Xin''s words are just consolation, but at this time, she can only choose to think about the good side.


    "I''m going to see what''s going on with my dad. Before that, I asked him to check the ground source heat pump." Chen Xin said to Qin LAN and Mo Qingyan, and then went to the room where the ground source heat pump was installed.


    In the room, Chen Xin''s father is checking the operation of ground source heat pump equipment and recording it in a book.


    "Dad, how''s it going?" Chen Xin asked his father.


    "At present, all the equipment are running at full load, in good condition for the time being, no problem." Chen Xin''s father put away his pen and answered Chen Xin''s question.


    For Chen Xin''s father, who has worked with mechanical equipment all his life in the factory, these ground source heat pumps are just a piece of cake for him. However, these ground source heat pumps involve the heating of the whole refuge, and he is very serious about it.


    So after answering Chen Xin''s question, he continued to say to Chen Xin, "now all the equipment is running at full load, and there is no standby equipment. In case of a failure that causes the equipment to stop running, do you have any remedial measures?"


    "Don''t worry, Dad. I''m prepared for that." Chen Xin is really not worried about equipment damage. He is only worried that the temperature will continue to drop, and these equipment will not meet the heating needs.

 Chapter 282

    Chen Xin is only worried that the boiler can not meet the heating needs, but in the urban area, this problem has become one of the most important problems faced by various shelters, which has brought severe challenges to the survival of the survivors in the shelters.


    The boiler inside the refuge is coal-fired boiler. Compared with oil-fired boiler or other heating methods, this kind of boiler has low operation cost and mature technology. But before the disaster, it has been gradually eliminated due to environmental protection problems, and its thermal efficiency is not as good as the new gas-fired boiler.


    But the coal-fired boiler is the most suitable heating equipment after the disaster because of its mature technology, relatively simple maintenance and easy storage and transportation.


    After all, the cost of new boilers, whether they use natural gas or fuel oil, is higher than that of coal-fired boilers, whether before or after a disaster.


    But now the boilers in the shelters have reached the maximum power, just like the monsters devouring coal, they are devouring coal and sending out heat to supply the shelters, but they are still unable to meet the heating needs of the shelters, and the internal temperature of the shelters has already dropped below zero.


    After the shortage of power supply due to the shortage of coal in the urban area last time, the municipal government considered whether the heating would be affected under the shortage of coal, and strengthened the cold proof and heat preservation measures inside the shelters.


    In theory, even if there is no heating, even if it is 40 degrees below zero, it can ensure that the indoor temperature is not lower than zero.


    But now in the face of the extreme cold of minus 70 degrees, even if the boiler has been continuously heating, the internal temperature of each shelter has been below zero, and it is still further reduced with the bad weather.


    Although the low temperature below zero for the human body can resist and adhere to, wear more clothes, more activities, and there will be no freezing death, but all kinds of diseases and frostbite caused by low temperature bring huge pressure to the medical system.


    Moreover, in order to maintain body temperature, the human body will need to consume more food in low temperature environment, which is also a great test for the food reserves of various shelters.


    In this case, the elderly and children are often the first to fail.


    As a result, the infirmaries of various shelters are full of old people and children who come to see a doctor, and the serious cases need to be sent to the hospital.


    The surge of patients has also made the supply of drugs in a tense state. The medical system itself has also entered the overload state of the heating system. If patients surge further, the medical system will face collapse.


    In the hospital, even Hong Rui, a former psychiatrist, was taken out to the emergency department to help, working continuously for more than 16 hours.


    But there is still a steady stream of patients were sent to the hospital, most of them are caused by hypothermia complications and frostbite of various parts, although it is not difficult to deal with, but patients have been sent, or to the hospital medical staff brought great pressure, also let them have no time to rest.


    Frostbite treatment is not particularly troublesome, just let the patient out of the low temperature environment, let the frostbite parts warm again, keep dry, do a good job to keep warm, serious can be coated with frostbite ointment for treatment.


    But this is a very complicated and troublesome process, because frostbite can not be roasted by fire, only warm water can be used to warm the frostbite parts, and warm water can be used for half an hour to one hour.


    In this low temperature environment, the warm water will cool down soon, so someone must change the water constantly.


    What''s more, the frostbite cases sent to the hospital are more serious, which need further treatment, which aggravates the workload of doctors.


    In order to avoid that all doctors are overworked, resulting in no doctors available, the hospital is also adjusting the personnel, so that doctors who have worked for more than 10 hours go to rest first, and at the same time, people from other medical departments who are not very busy are transferred to supplement, so as to maintain the operation of the medical system.


    Because Hong Rui had been busy for more than ten hours, she became the first batch of doctors to be replaced.


    At this time, Hongrui was already very haggard, no longer the delicate appearance that Chen Xin had seen before.


    In fact, Hongrui''s appearance is good, but her face is haggard, and her dark circles are a little heavy. Other doctors even get blistered and peeled because they have been massaging the frostbitten parts with their hands.


    The doctor who was replaced to rest fell asleep after sitting down on the chair in the rest room, and their last trace of energy had been drained by more than ten hours of continuous work.


    Looking at the coworkers slumping on the chair, Hong Rui can''t help worrying. If this continues, what should we do if everyone is tired.


    However, she has no good way to solve this problem. In addition to working continuously for more than ten hours, Hongrui can only go back to her office to have a good rest and raise her spirits, so that she can support for a while later when she is on shift.


    As she walked to the office, the hospital corridor was full of patients.


    Some of these patients have been treated or are in the process of treatment, while others are still waiting for treatment.Because of the pain, quite a few of them are groaning in pain. In addition to the crowding and cold, it looks very uncomfortable here, as if it is full of suffering.


    Seeing this situation, Hong Rui''s heart is more worried. Obviously, the patient can''t get timely treatment, which is enough to show that the medical system has exceeded its load capacity. In this way, it will only make things worse.


    This makes Hongrui feel more and more heavy. She goes back to her office through the crowd. Without even taking off her shoes, she lies on the sofa in the office and is ready to go to bed. In order to work better, she must hurry to sleep.


    In fact, if Chen Xin knew what was happening in the urban shelters, he might sigh that "ice age" was not deceiving me.


    Although "ice age" is a serious game of private goods, a sentence "is it really worth it" is just bullshit, which is a complete mockery of order is not as good as faith.


    But many of the settings in the game are very real. At least when the temperature of the living environment is too low, it will lead to more patients. Patients will leave their jobs, leading to the collapse of the work efficiency of various facilities. There are not enough beds in the medical system, which will make the patients from mild to severe, and the severe patients will continue to die after they continue to receive no treatment. This is really no different from the reality.


    In the urban shelters, what is happening now is such a scene. Even compared with the game, there are still a few days to turn the situation around. As long as more medical facilities are built, the problem can be solved. In reality, it is more difficult to turn the situation around.


    Unless the temperature rises again, the situation will only get worse, even worse because of the shortage of coal supply.

 Chapter 283

    In the shelter of the city police station, Ding Ning is wearing a thick duty coat and wrapping himself up. He is standing in the canteen to maintain order.


    Because of the continuous low temperature, the temperature inside the shelters even with continuous heating has dropped to more than minus 10 degrees. The city government finally used the emergency reserve to provide additional meals for the survivors in the official shelters, so that they can get more heat to resist the cold.


    At first glance, it seems that there are some problems, but in theory, there are no problems, because people get life sustaining calories by eating.


    Many people may have had such an experience. If they don''t eat in winter, they will feel very cold. But after a bowl of hot soup, they will soon warm up because the food brings heat to the body.


    So as long as there is enough and warm food, it can provide enough heat, so that people can resist the cold.


    It is for this reason that the city government has used the emergency reserve that has not been used before to provide various shelters with meals for the survivors.


    In view of the current grim situation, although the meal increase was announced, in order to prevent people from disturbing the order, police forces were used in various shelters to maintain order in the restaurant, so as to ensure that all people can eat in an orderly manner and get their own food.


    Even if the shelter of the city police station is full of policemen and their families, it can not be exempted.


    Although no one is likely to make trouble, if there is no one to supervise the order, it is inevitable that some people will want to jump in the queue, or muddle through, and want to have a second meal.


    Although the municipal government has opened up emergency reserves and provided a lot of food, it can only let everyone eat one portion at a time, and it is impossible for people to open up to eat.


    As for the food itself, it is a thick rice porridge with a large amount of protein powder made from bread worms and dehydrated vegetables and meat in emergency reserve.


    This is a very rare meal for the survivors who have not eaten serious meat for nearly half a year.


    In fact, the situation in the police station is a little better than that in other shelters. To be exact, the temperature in the area where the special police live is a little higher.


    After all, the ground source heat pump provided by Chen Xin was installed before. In addition to providing hot water, this set of equipment is for heating.


    This also makes the temperature of the SWAT team three or four degrees higher than that of other places in the shelter of the city police station. Although it is also below zero, at least it is not so difficult.


    "Ding Ning, what''s the situation here?" When Ding Ning was looking at the crowd in the dining hall, the commissar came to her and asked her about the situation.


    After a salute, Ding Ning replied, "report to the political commissar that everything is normal at present. Everyone is having a meal in an orderly way. There is no accident."


    Maybe it''s all the family members of the police and the police who take turns. They are better than other places in keeping order. In addition, the food and heating conditions of the special police force are better than those of other places. Naturally, people are not particularly greedy for this stutter.


    But in today''s world, if adults don''t go out to work, it''s hard to have enough food. They can only barely get half full. A child may be able to eat enough with a ration, but for adults, it''s nothing more than not hungry.


    Therefore, to be able to eat one more meal is attractive enough for everyone.


    The political commissar naturally knows the situation. Of course, he didn''t come to Ding Ning specifically to ask her about her duty. Naturally, other people will report this to him.


    His real purpose is to care about Ding Ning himself. After all, Ding Ning is uncle Ding''s daughter. Although uncle Ding, as the captain of the special police force, has not given special care to Ding Ning, the political commissar, as his old partner, should still care about Ding Ning so as not to encounter any problems here that may affect uncle Ding''s work.


    So after asking about his work, the political commissar also said to Ding Ning, "don''t be so serious, just chat casually. I can still remember that when I went to your house before, you called me uncle. Your father didn''t take you to the playground, you asked me to take you out to play."


    When the commissar talked about his childhood, Ding Ning was a little shy, but he quickly said seriously, "it''s all about childhood. Dad said that he should be more serious at work."


    "All right, but how are you doing now, Ning Ning? Your father is busy with work and has no time to care about you. I heard that you are living outside alone now. Is that ok? " The commissar was concerned about Ding Ning''s situation and advised her, "don''t take it easy on yourself and your father. He is really busy and has no time. It''s not that he doesn''t care about you. You live outside alone, but he told me several times that he was worried about what danger you might encounter outside. Why don''t you move back, Ding Ning? "


    "Political commissar, it''s not like this. I lived outside because I had to take care of my friends'' house before. And originally sister LAN lived with me, but after she had an accident, I lived alone. I didn''t get angry with my father. It''s unnecessary." Ding Ning shook her head. Although she did have some conflicts with her father, she was not so angry.


    Hearing Ding Ning say so, the political commissar was relieved, but he turned to care about whether there were any problems in Ding Ning''s life: "Ding Ning, do you need any help in your life? Although we are short of materials and limited conditions, we can still help you a little bit. ""Help me? No, my friend''s conditions are very good. Ground source heat pump, fish and vegetable symbiosis and microalgae oxygen production are all available. Two or three people can live without relying on the outside world. " Ding Ning counted what Mo Qingyan''s family had and felt that he didn''t need anything extra.


    Of course, in the current extreme cold of more than minus 70 degrees, even if Mo Qingyan''s house is equipped with ground source heat pump, the temperature is also below zero, and even the vegetables are frozen. If it wasn''t for the fish vegetable symbiosis system that was connected with ground source heat pump before, I''m afraid all the fish in the pool would freeze to death.


    But even so, Ding Ning doesn''t feel that there is any place where she needs help living in Mo Qingyan. After all, the help that the political commissar can provide here is nothing more than supporting some materials. But now that resources are scarce everywhere, Ding Ning thinks that these materials should be left to those who are in more need, rather than to those who are not worried about food and clothing for the time being.


    Hearing what Ding Ning said, the political commissar could only care a few more words. At the same time, he told Ding Ning to go to him if he needed anything in life. Then he left the canteen.


    Ding Ning is worried about Chen Xin. Among the people she knows, Qin LAN, Mo Qingyan and Chen Xin are all living together now. If they have any problems because of the snowstorm, she really can''t even save people.

 Chapter 284

    When Ding Ning is worried about Chen Xin, Chen Xin, Qin LAN and Mo Qingyan are also worried about Ding Ning in the city.


    The snowstorm, which has lasted for several days, shows no sign of calming down. The gate of the shelter is about to be buried by snow. In this case, even if the snow stops, they will have to dig a big hole at the gate.


    In fact, not only the gate, but also the observation door of the observation room has been covered with snow and covered with frost.


    Now in this situation, even if Han Ping proposed several times to let him go out in protective clothing, at least to clean up the snow outside the observation port, Chen Xin did not agree.


    After all, with such deep snow and cold weather, even if Han Ping had protective clothing, it was very dangerous to go out.


    But the more so, the more worried they are about the situation in the urban area.


    Even they are in such a situation here. Aren''t all the shelters in the city going to be covered with snow?


    However, considering the underground roads that connected the various shelters, Chen Xin was not worried that the shelters were completely buried in snow and cut off from inside and outside, and all the people inside were trapped. After all, after the underground transportation network was opened, there were no problems in the supply of materials and the transportation of coal.


    What really worries Chen Xin is whether the urban refuges can cope with the extreme bad weather rarely seen in the north and south poles even before the disaster.


    Chen Xin doesn''t think that in this kind of indoor weather where water can drip into ice, people can afford without enough heating.


    "Ah Xin, do you think there will be any danger over there? She lives alone with Qingyan. I''m afraid she won''t be able to hold on. " Qin LAN watched Chen Xin busy in front of his desk. Although she couldn''t bear to disturb Chen Xin''s work, she expressed her concern to him.


    Hearing Qin Lan''s words, Chen Xin looked up at her, put down her work, and nodded: "Xiaoding is a little dangerous. Although I installed a ground source heat pump for longniang, I should not worry about heating, but the heat efficiency of a ground source heat pump is limited. In this kind of weather, I''m afraid that her indoor temperature can reach minus 20 degrees is a good measure to keep warm It''s over. "


    Chen Xin''s words are no exaggeration. The outdoor temperature is more than minus 70 degrees, the indoor temperature is more than minus 20 degrees, and the indoor and outdoor temperature difference reaches more than 50 degrees, which is enough to prove the heating effect of ground source heat pump.


    After all, before the disaster, under normal circumstances, it was very cold when the outdoor temperature could reach minus 20 or 30 degrees. Even in Northeast China with heating, the indoor and outdoor temperature difference was only 40 or 50 degrees.


    But now the outdoor temperature is more than minus 70 degrees, and the temperature rise of 50 degrees can''t bring the indoor temperature back to zero. It must have a temperature rise of at least 70 or 80 degrees.


    But for the general heating equipment, they are not designed to be used for heating in this extreme environment, and to achieve this effect, there are requirements for the cold proof and warm keeping effect of the building itself.


    "What can we do for her? I''m afraid the situation in the urban area is not optimistic. I think we should do something. " Qin LAN knows that his words are a little too much. Now, it''s very rare for Chen Xinneng to take good care of himself. How can he have the energy to take care of others?


    Thinking of this, Qin LAN quickly added: "I''m just saying this, Xin, don''t force me."


    With that, Qin LAN felt that he was a little hypocritical. He didn''t know how to explain it. The whole person froze.


    Chen Xin doesn''t think Qin Lan''s words are wrong. Helping others when he has the ability or doing something that can make more people live better is actually a kind of self sublimation.


    Qin Lan said that she thinks she should do something, which is decided by her own career. As a policeman, it''s strange if she doesn''t think about what she can do in this situation.


    Even if she is no longer an active police officer, that will not change.


    So Chen Xin just gave her a smile and explained to her, "I want to do something, but the problem is that in this situation, unless I can build a giant energy tower that can heat the whole city in the ice age, it will be very difficult to change the situation."


    ¡°¡­¡­¡± Qin LAN some loss of low head, this kind of thing even if is to use to think of also know impossible.


    But Chen Xin is obviously not the one to make fun of this kind of thing. After all, he has a system. Even if he really wants to build an energy tower, it''s not that he can''t build it. It''s just that there are too many things to do, and it can''t be completed in a short time.


    Chen Xin actually has another plan.


    "So I''m going downtown to see if there''s anything I can do to help." Chen Xin tells Qin LAN what he thinks.


    "Downtown? But how can you get to the city in such a big snowstorm outside? Even if your car can go downtown, you can''t get out now! " Of course, Qin LAN knows that the gate of the shelter has been buried by the snowstorm. In this situation, it''s hard for her to imagine how Chen Xin will go to the city.


    "The car can''t drive out before the snow stops, but it doesn''t say that people can''t get out." Of course, Chen Xin knows that his car can''t be driven out in this weather. After all, the snowstorm outside is so severe. Although his car is heavy enough not to be blown away by the wind, it''s also very difficult to drive to the city.When Qin LAN heard Chen Xin''s words, she had a little idea, so she asked Chen Xin tentatively, "do you mean the exoskeleton protective suit you made? If you wear that, you can really try to go downtown, but it''s still too dangerous, isn''t it? "


    "The protective ability of exoskeleton protective clothing is limited, and it''s a little too reluctant to resist this kind of snowstorm. Although the low temperature is no problem, the strong wind of level 12 can''t be resisted by a suit of protective clothing made of cloth." Chen Xin shook his head, picked up the thing he was making on the table and handed it to Qin LAN: "remember the power armor I told you about?"


    Qin LAN took what Chen Xin handed over. It was a metal glove similar to her red power glove.


    Looking at this metal glove, Qin langdeng understood it and asked Chen Xin in surprise, "are you going to make power armor and then go downtown in power armor?"


    "Well, I''ve solved the energy problem. The small isotope thermoelectric battery is enough to support the energy consumption of a set of power armor. The strong metal shell can also resist the attack of strong wind. The heavy enough weight can completely guarantee that I won''t be blown away. With such a set of equipment, I''m sure I can go to the city." Chen Xin said confidently.

 Chapter 285

    In fact, after Chen Xin finished the production of exoskeleton protective clothing, he can actually make power armor. The difference between the two is that there is only one more layer of protection.


    Now it''s not a time to worry about whether to solve the problem by oneself, so Chen Xin directly made two sets of protective clothing with the drawings of exoskeleton protective clothing stored in the workbench, and then directly upgraded to power armor.


    For power armor, Chen Xin adopts a structural design similar to the T Series in radiation, which can be unfolded from the back, and then people can enter it and completely close it.


    The whole power armor has a thick and solid composite outer armor, and there are protective armor plates at key parts. It is powered by a small nuclear fusion battery. Under the condition that the battery is not damaged, the whole armor can run for ten years without shutdown.


    It is equipped with a set of life support system. Because of the temporary rush work and Chen Xin''s lack of understanding of this, this set of life support system only monitors the user''s vital signs and some simple drug injection and emergency hemostasis. Its main function is to monitor the blood oxygen content and deliver oxygen.


    Although the ugly T-series power armor design in radiation is used in the structure, Chen Xin still can''t accept the evil empire style helmet in appearance. In addition, the original exoskeleton protective suit adopts the style of motorcycle helmet, so after the upgrade of the whole armor, it looks more like the 50 pieces of good brothers in StarCraft.


    The whole set of armor is black. It seems that all parts are thick and round, and there are no sharp edges. The helmet is not independent, but is directly integrated into the armor like the "StarCraft" brothers. It has two layers of protective masks. The outer layer can be opened, while the inner layer generally does not open, so as to maintain the internal sealing of the power armor.


    Two sets of ready-made power armor are parked beside the worktable. The rear part of the whole power armor is fully expanded. If you want to put on this set of power armor, just go in and start it.


    Seeing Chen Xin make two sets of power armor, Qin Lan''s eyes are full of exclamation and can''t help saying: "is this really power armor? Can I have a try? "


    "Try it, but I need to remind you that the power armor I use is a force feedback power way, that is, when you make an action, the armor will assist with the force, so when you do the action, don''t make too much range, in order to avoid danger." Chen Xin didn''t stop Qin LAN from trying. He motioned to her to take off the power gloves on her right hand prosthesis and then said that she could go in.


    Qin LAN with a nervous mood, according to Chen Xin''s tips, stood behind the power armor, looking at the open power armor behind the human shaped groove, asked: "do you want to take off your shoes?"


    "No, the interior space of the armor is self-adaptive, not tight or loose, ensuring comfort." Chen Xin smiles and signals her to step on the feet of the power armor and put her head into the helmet first.


    When Qin LAN felt that her body had fitted the armor, her hands were naturally put into the arms of the power armor.


    "And then?" Although Qin Lan was a little nervous, after taking a deep breath, he was full of expectation for power armor.


    "And then? "Start up." With a smile in his voice, Chen Xin walked into a set of power armor beside him and said, "start up!"


    With Chen Xin''s voice, the back of the power armor he entered automatically closes, the power system is connected, the locking mechanism locks all the parts of the armor that were originally opened, the air valve automatically empties the excess air, seals the power armor and insulates the inside and outside, and the life support system starts to work.


    Then the inside of the helmet lights up, and the operating system installed in the helmet starts to self check, and displays the situation of the helmet, so that Chen Xin can see the situation of the whole suit of armor without turning his eyes.


    Qin Lan also finished her dress according to Chen Xin''s instructions, but she didn''t dare to move because of Chen Xin''s warning just now.


    "Well, after the armor is activated, it will automatically turn on radio communication. You can talk to me through the built-in intercom in the helmet. Now the default mode is intercom mode, which is a team channel." Chen Xin went to the front of Qin LAN and let her see herself. Then she reached out and pressed a button next to her helmet: "this button can be switched. Pressing it is an internal call, two full channel broadcasts, and holding it is an external call."


    Qin LAN heard Chen Xin''s explanation and wanted to raise her hand to have a try. However, because she was not familiar with the operation of power armor, she restrained her thoughts and just said through the helmet phone: "I know, how to operate this armor? I''m afraid to move now. "


    "This is actually very simple. You try to lift your arm gently. If you worry about your right hand, just use your left hand. It''s very common to lift it slowly." In fact, Chen Xin is not familiar with the operation of power armor, but he made it himself. He has the experience of operating exoskeletons with the same principle before, so he can get started quickly and provide teaching for Qin LAN.


    According to Chen Xin''s suggestion, Qin LAN controls her left hand and raises it slightly. She can obviously feel the burden of her left hand, but it is not heavy.However, because she didn''t put the palm of the power armor in her hand, it was like a puppet raising her hand.


    "The control of the palm is realized by the control lever held by your finger. You can use any finger you want to move. Now try to move your finger." Chen Xin saw that Qin LAN had successfully raised her hand, so she went on with the next step of teaching.


    While Chen Xin and Qin LAN are teaching power armor, Mo Qingyan and Mo Qingxin are also around. They are very envious that Qin LAN can be the first to try power armor.


    Mo Qingxin may be just pure envy, but Mo Qingyan''s heart is somehow jealous of Qin LAN. She can''t help but say to Chen Xin, who is teaching Qin LAN how to walk in Power Armor: "food, it''s good. How about a whole one for me?"


    "Do you want it, too? Yes, but I''ll have to wait a few days. I''m going to go to the city with Alain first, and I''ll make another set for you when we come back. Xinxiaomei also has one. " Chen Xin takes a look at Mo Qingxin and makes a promise.


    Hearing Chen Xin say so, Mo Qingyan nodded: "OK, but I don''t want this kind of black look. Can you paint it for me?"


    "Painting? It''s casual. Black is just that I''m too lazy to spray paint. If you want to make it look better, you can spray any color. " It''s just spray painting. Naturally, Chen Xin won''t refuse Mo Qingyan''s request.

 Chapter 286

    After a day of practice, Qin LAN basically mastered the use of power armor.


    Of course, this kind of mastery is only for the normal operation of wearing power armor. It is still a long way to get familiar with the performance of power armor and give full play to it.


    Apply the settings in the game is to learn skills, can be used out, but proficiency is basically zero, no power.


    However, in general, Qin LAN did not fall on the ground when he was walking in power armor, nor did he smash his helmet because he raised his hand too much. He was also familiar with how to pick up objects with the arms of power armor.


    Under such circumstances, she can wear power armor to accompany Chen Xin to the city.


    Just when preparing to start, Qin LAN is very concerned and asks Chen Xin, "don''t we need to prepare weapons? Although the main problem we have to face when we go to the urban area is Blizzard, if we meet dangerous elements, there will still be danger without weapons, right


    "Dangerous people? What kind of dangerous elements do you think can fight against a power armor? " Chen Xinchong and Qin LAN smile, but only ask her a question.


    Although he knew what Qin Lan said was true, and he could indeed equip power armor with weapons, it was unnecessary.


    First of all, this is power armor. The whole body is wrapped by steel plates of at least 3 mm. There is a composite buffer defense structure inside. The main parts are all thickened and reinforced. There is also an outer armor of more than 5 mm thick. The surface is carbonized and coated. The hardness is amazing. At the same time, the circular structure can easily eject bullets.


    With the defense of this armor, even if you are shot by a pistol or an automatic rifle at close range, it will not cause any damage. At most, it will rub off a layer of paint.


    If you want to destroy such a set of power armor, you will not have any damage unless the rocket launcher or grenade is thrown at your feet.


    Power armor itself has a strong power output, arms can easily lift 2.5 tons of weight, running speed can reach 40kmh, Chen Xinzhen does not know what kind of dangerous elements in the country can fight against such a power armor, and what is the need to use weapons.


    In addition, the oxygen supply of the internal life support system can provide 40 hours of oxygen in a vacuum environment. The air filtration function can ensure that the user can survive in a harmful environment for more than a week. It also has its own drinking water filter and an emergency compressed biscuit that can support for three days. It can also send a distress signal and persist until the rescue arrives.


    What''s more, they didn''t go to the war zone, they just went through the blizzard into the city.


    Qin Lan also reflected that she thought badly. She assessed in her mind what she would do if the SWAT team she used to be in was faced with such a power armored machine. The result is that in the case of no heavy weapons, even if the power armored machine has no weapons, a SWAT team member in the case of no heavy weapons, unless he can wear it with a sniper rifle If the armor bullet penetrates the mask and directly blows the head, otherwise, it is difficult to cause any effective damage to the power armor.


    After all, in order to show her the defensive power of the power armor, Chen Xin asked her to take his police pistol and shoot the power armor at close range. As a result, the surface of the armor didn''t even leave a mark, only a little paint was scraped off.


    Although the two men''s power armor did not carry weapons, they each carried a 20 liter cylindrical bag on the back of the power armor, which contained some emergency supplies. They planned to bring them to Ding Ning after entering the urban area. In addition, Qin LAN insisted that Chen Xin put the pistol in the power armor and carry it with him.


    One of the main purposes for Chen Xin and Qin LAN to enter the urban area is to check the situation of Ding Ning. Of course, what''s more important is that Chen Xin wants to get in touch with the branches of scientific research institutions stationed in the urban area, learn more about the situation, and see what he can do.


    After finishing the packing, they opened the gate of the shelter. Relying on the brute force of the power armor, they made a way out of the snow that had piled up to the top of the gate and left the shelter.


    Looking at the shelter door behind him closing, Chen Xin and Qin LAN turn on the light on the shoulder of the power armor, step forward and backward in the waist deep snow and walk towards the city.


    "It''s snowy. I can''t see the direction clearly! A Xin, how can we determine the way forward? " Qin LAN looks at the snow on the mask and asks Chen Xin.


    The light on the shoulder of the power armor is only equivalent to two flashlights. In such a blizzard, only a few meters in front of the two power armor can be illuminated. In such bad weather, even if there is sunshine, it is difficult to confirm the direction by naked eyes, let alone the long night when you can''t see your fingers.


    However, Chen Xin obviously considered this problem, so he said to Qin LAN: "you try to use voice to say ''turn on the navigation''. I have uploaded the map and the forward route to your power armored system. The navigation system comes with compass, small map and positioning, so that even if you lose your way in the snowstorm, you can find my position."


    Hearing Chen Xin say so, Qin LAN starts the navigation system, and sees a map of the same model as the mini map in the game appear in the upper right corner of his perspective, and there are yellow lines on the map to indicate the way forward and red dots to indicate Chen Xin, so he can safely follow him through the snowstorm.Qin LAN and Chen Xin, who are braved by the snowstorm, can only see the endless darkness in front of their eyes except the gray and black snow flakes illuminated by the light. Besides the sound of the wind and snow which is not obviously blocked by the helmet and mask, they can only see each other''s voice.


    If you don''t know that there is a shelter behind you, that you are surrounded by companions, and that you need to go to the city in front of you, in such a dark and lonely environment, you may forget how long you have been walking, lose your direction, and eventually freeze to death in the ice and snow.


    This kind of thing is not uncommon. Even with the blessing of modern technology, it is also a very dangerous thing to encounter a snowstorm outdoors. Every year, people will be frozen to death in the wind and snow.


    Fortunately, Qin LAN and Chen Xin didn''t have a long way to go. With the help of power armor, they only spent more than an hour walking to the bridge connecting the urban area.


    The bridge has been completely invisible in the snowstorm, only a few faint traces can make people recognize that this is the original location of the bridge.


    Through the light from the power armor, we can even see the snow under the bridge, and even the piers are about to be buried, which will completely engulf the whole bridge in the ice and snow.


    "It seems that the performance of the power armor is not bad. We can enter the city through the river." Chen Xin praised the power armor he made, and then took Qin LAN to step on the snow from under the bridge, across the river and into the city.

 Chapter 287

    In the dark and endless snowstorm, Chen Xin and Qin LAN finally crossed the street completely covered by snow and came to the gate of the city police station.


    The original guard box has now been completely buried in snow, even the top can not be seen, and the gate has no trace.


    The magnificent police station building seems to be a little better than when Chen Xin came last time. Under the light of the power armor, Chen Xin can see that the broken glass on the whole building was repaired because of the disasters after the meteorite impact.


    But the first floor of the building has been completely covered by snow, and the thick ice and snow has even piled up to the windowsill on the second floor.


    "Will the entrance of the shelter be buried in such heavy snow?" Chen Xin looks at the ground which is almost filled with snow in front of him, and asks Qin LAN in some dilemma.


    The refuge of the municipal police station is a medium-sized official refuge nearest to the refuge of Chen Xinjia, so Chen Xin and Qin LAN will arrive here after leaving the refuge of Chen Xinjia and entering the urban area.


    However, looking at the snow all over the ground, Chen Xin was obviously worried that the entrance to the shelter was blocked by snow.


    Qin LAN is not sure about this, but she still takes Chen Xin to the police garage with her memory: "go to the garage first. It''s one of the main entrances and exits of the underground refuge, and it''s connected to the underground highway. It shouldn''t be buried there."


    Hearing what Qin Lan said, Chen Xin nodded and walked towards the garage with her.


    However, the situation is worse than they expected. The snow has buried the garage, and the gate of the garage is completely covered with snow.


    "It looks like we''ll have to change the way." Looking at the thick snow in front of Chen Xin''s eyes, he felt a little scratched.


    After all, they also came to the city to find Ding Ning, who lives in Mo Qingyan''s house. Now the snow is so thick that nine out of ten Mo Qingyan''s house has been buried in the snow. The elevator entrance is probably not usable.


    This makes Chen Xin worry about the condition of Mo Qingyan''s home, which is likely to be frozen into an ice cellar and abandoned.


    Although this situation is almost inevitable in the current bad weather, it is mo Qingyan''s and Mo Qingxin''s home. Even if they live in Chen Xin''s home now, when do they want to go back to their home?


    You can''t let them dig their house out of the snow first, can you?


    If possible, Chen Xin still hopes to find a way to keep Mo Qingyan''s home.


    But before that, he and Qin LAN still have to find a way to enter the shelter of the city police station, so that they can know where Ding Ning is now.


    "Let''s try to find a window to enter the building. There are entrances and exits to the garage in the building. Should they be closed?" Qin LAN suggests to Chen Xin, and at the same time, she also recalls how to get to the passageway leading to the garage inside the police station building.


    Chen Xin, of course, is not familiar with the city police station. At this time, she can only follow her advice.


    They came to the building together and looked at the building in front of them. Chen Xin asked Qin LAN, "how do we get in? Do we climb in through the broken window?"


    "Now it''s the only way. Find a window by the corridor, and we''ll go straight in." Qin Lan''s attitude is very decisive, with Chen Xin directly came to a window.


    As a special police officer, although Qin LAN has been trained to break the window many times, it''s the first time for her to break the window into the office building of her police station.


    Standing in front of the window, Qin LAN didn''t hesitate and think much, but after taking a deep breath, he directly raised his fist, and then controlled the power armor, smashing the window glass in front of him.


    Qin LAN smashes the whole glass window into glass slag in the moment when he hits it with his fist. Although he is not very proficient in the operation of power armor, the tactical action that has already formed muscle memory makes Qin LAN turn in cleanly.


    Chen Xin also climbed in from the window broken by Qin LAN.


    Two people stand in the corridor, shoulder light shining on the corridor, it is very clear that there is no snow in the corridor, but the walls on both sides and the ground are already covered with frost.


    Chen Xin asked Qin LAN, "go down? Or does it mean there''s no garage here, so you have to go inside the building? "


    "This staircase only goes to the first floor. We need to get inside the police station and go down another staircase to get to the garage." Qin LAN looked up and carefully identified it before giving the answer to Chen Xin.


    Chen Xin just nodded, then followed Qin LAN up the stairs, through a door into the police building.


    There is also a small episode here, that is, the foot area of power armor is obviously much larger than that of normal people, and the stairs in the police station building are designed for normal people, which makes Qin LAN and Chen Xin encounter a lot of trouble when they go up the stairs.


    Fortunately, the performance of the power armor was good, and the built-in gyroscope for balance also worked well, so they went up the stairs after a little effort.The interior of the police station building is dark at the moment, which is completely illuminated by the light on the shoulders of the two men''s power armor. This kind of environment makes Chen Xin feel like he is playing some kind of adventure game, or the kind of horror game of the eighteen prohibitions.


    Of course, reality is not a horror game. Although there is a shelter under the police station building, there is no bald head in a green army coat, no disgusting monster, and no skinned toad that can pop eight meters away from the ceiling. Chen Xin is not a vehicle killer himself, and Qin LAN does not wear a red cheongsam.


    But think of this, Chen Xin can''t help but come up with an idea in his mind, maybe he can try to let Qin LAN wear Qipao another day?


    Taking this idea down, Chen Xin follows Qin LAN quickly through the already empty corridor and the office with some traces of use, and goes to the stairs leading to the underground garage.


    Previously, the police station building was restored and several floors on the ground floor were put back into use, but now with the blizzard raging, these floors on the ground have obviously been abandoned again, leaving only some traces of hasty evacuation.


    Obviously, when the snowstorm came, the people who were still working here were not informed and prepared. They were in a hurry to evacuate to the underground shelter.


    Chen Xin and Qin LAN go down the stairs to the underground garage, where the door is really closed.


    "Knock on the door, or violence?" Chen Xin stands in front of the closed fire door leading to the underground garage. He can''t open it, so he looks at Qin LAN.


    Qin LAN directly replaced the answer with action and directly knocked the door open.

 Chapter 288

    The moment Chen Xin and Qin LAN open the door, people in the underground parking lot are shocked. Several police officers with quick reaction quickly pull out their guns and hide behind the bunker to take aim.


    However, two black steel monsters came out from behind the door which was knocked open. They were stunned when they saw it. They didn''t know whether they should shoot or not.


    The reason why they wanted to shoot was that the two iron monsters looked terrible. They were all black and cold. They broke through the door. At a glance, they didn''t look like good men and women.


    But after weighing the pistol in their hands and looking at the thick armor on the other side, they don''t think that the pistol in their hands can cause any harm to the other side. Shooting rashly may irritate the other side.


    Fortunately, after breaking the door, Qin LAN and Chen Xin did not show a tendency to attack, Qin Lan also quickly opened the outside to shout, to the police showed their identity.


    Hearing Qin Lan''s identity, the police officers put down their heart and took back their guns. They came out from behind the bunker and came to Qin LAN and Chen Xin.


    "Qin LAN?" There is a policeman who knows Qin LAN. He can''t believe it, because Qin Lan''s power armor looks too incredible.


    "It''s me. How''s the situation in the bureau?" Qin LAN opened the helmet''s mask, revealed his face, to the police in front of him to listen to the situation.


    Seeing that it was really Qin LAN, the police officer took a long breath and said to her, "I''m scared to death. I thought it was some kind of alien monster that came in! You are so handsome


    "The situation in the bureau is not optimistic. The weather is too cold. Many people suffer from hypothermia. There are also a lot of people suffering from frostbite. But now the whole city is basically like this. The situation in the bureau is still good. At least you special police team can take a hot bath to treat frostbite." Another police officer also said to Qin LAN, although the tone seems very indifferent, but it shows a bitter taste: "other places can be difficult, many people after frostbite simply can not get timely and effective treatment, can only be sent to the hospital, now the hospital is also unbearable, in such a situation, I''m afraid it''s really going to happen."


    Hearing what the police said, Chen Xin and Qin Lan''s faces became a little ugly. Although they expected that the situation in the urban area would not be very good, they did not expect that they had reached this point.


    Especially if it''s just what the other person says, it may actually be worse.


    In the face of this situation, Qin LAN rushed to the police to listen to Ding Ning''s news: "do you know Ding Ning''s situation? How is she now? "


    "Ding Ning is OK, she is now in charge of the order maintenance of the special police canteen, no problem." The police officer answered Qin LAN, suddenly showed a concerned expression and asked: "Qin LAN, what are you doing here?"


    "We were in the suburbs before. We saw a snowstorm. We were worried about the situation in the city, so we came to see if there was anything we could help." Qin LAN explains to the police why she and Chen Xin come here.


    Hearing Qin LAN say that he came from the suburbs, two police officers showed an unbelievable look on their faces. But looking at Chen Xin and Qin Lan''s power armor, they believed what they said. After all, with such power armor, they can really break through the snowstorm.


    However, this is not the point. After hearing that Qin LAN and Chen Xin came to see if they could help, the police officer thought about it and said to them, "we don''t know what we can help. Go down and ask the person in charge below."


    The police didn''t stop Qin LAN and Chen Xin from going down. On the one hand, they couldn''t stop them. On the other hand, Qin Lan was also a member of the special police force. Although she was trained because of her disability, her identity has not changed. She is still a policeman of the special police force.


    So after Qin Lan said that he was here to help, the two police officers directly chose to believe it. After informing the shelter below, they let them go down.


    Chen Xin and Qin LAN wear power armor down to the shelter interior, arrived at the floor where the special police team.


    Two people out of the elevator, Ding Shu and political commissar, as well as two armed special police are waiting for them in the elevator door.


    Seeing Chen Xin and Qin LAN in power armor, the four people waiting at the elevator door and the people passing by were shocked. The appearance of power armor is really shocking. After all, this kind of thing in science fiction movies is beyond the imagination of ordinary people.


    Fortunately, uncle Ding and political commissar were not ordinary people. They soon regained their composure and welcomed Qin LAN and Chen Xin, saying, "Chen Xin, Qin LAN, it''s really timely for you to come back at this time."


    "There''s no need to be polite. We''d better go straight to the theme in this situation. Is there anything we can do?" Chen Xin looked at Uncle Ding, but he didn''t show too much politeness.


    "This If it''s just manpower, we don''t lack it. Now the key problem is heating. Although there is still coal supply in the urban area, and it''s very difficult to send coal from outside, the comrades on the railway front are still working hard, so there is still coal, just.... " The political commissar looks helpless. It''s a good thing to have two people to help at this time, but there are too few things that two people can do."Is it a matter of temperature rise and thermal efficiency? If that''s the case, I can do something to help improve the boiler, which can improve the heating efficiency, but it may increase the consumption of coal. " When Chen Xin heard what the political commissar said, he immediately understood what was going on, so he indicated that he could help transform the heating equipment.


    Hearing this, both Ding Shu and the political commissar could not help but have a flash in their eyes. Although the increase in coal consumption will make the current reserves of coal run out faster, if the snowstorm continues and the coal is used up again, it will cause a greater crisis. But now we should raise the temperature first. After all, if it goes on like this, the coal may not burn out and people will freeze to death.


    "Then raise the temperature first! We don''t have enough coal. We can do something else! " Uncle Ding made a direct decision and asked Chen Xin to help transform the heating system: "political commissar, please call them first. Chen Xin, tell the political commissar what you need to transform, I''ll go to the director!"


    With that, uncle Ding went into the elevator, pressed the floor, and went to the director of the municipal police station to talk about the transformation of the boiler.


    Chen Xinze and Qin LAN follow the political commissar into the refuge.


    "In fact, in addition to heating, the current medical treatment is also a big problem, a large number of frostbite and hypothermia patients can not be treated in time, we can only let them take a hot bath to relieve." As the political commissar walked along, he was still talking about the situation here: "if it wasn''t for Comrade Chen Xin, you helped us install ground source heat pump before, I''m afraid the days would be even more difficult now..."

 Chapter 289

    In the shelter of the city police station, in the room where the ground source heat pump is installed, Chen Xin has taken off his power armor and is standing next to the ground source heat pump to check the condition of the equipment.


    The ground source heat pump is a very important equipment for the current special police force. It is precisely because of the existence of ground source heat pump that the special police force can still maintain a certain amount of heating and hot water supply in this extremely cold weather, so that some people suffering from hypothermia and frostbite can take a hot bath to relieve the pressure brought by the long-term low temperature environment It''s the harm that comes.


    But the heating of ground source heat pump equipment is limited. If the heating is maintained, the bathroom can not be opened for a long time, so now the bathroom of the special police team can only be opened once every other period of time. Only people with severe frostbite can go in for a hot bath to relieve frostbite.


    "Comrade Chen Xin, is there any way to improve the heating efficiency of ground source heat pump?" The political commissar stood beside Chen Xin, watching him check the equipment, and asked him with some expectation: "thanks to the set of equipment you sold to us, it really played a big role! Can we find a way to make the equipment produce more heat energy?


    Now we really need more hot water! If you can do it, whatever you need, just talk! Even if I throw these two hundred catties into the boiler and burn them, you don''t have to do it. I''ll jump in myself! "


    When Chen Xin heard the commissar say this, he laughed, shook his head and said, "it''s not so exaggerated! It''s a waste of fuel to burn corpses. The combustible content of human body is too low! What''s more, it''s materials that are needed to transform the equipment. How can we burn people? "


    "Comrade Chen Xin, what materials do you need? I''m going to have people prepare! " From Chen Xin''s attitude, the political commissar saw that he had a good idea. He quickly asked him what materials were needed for the transformation. It seems that he can''t wait for Chen Xin to transform the ground source heat pump.


    "I need to add two compressors, the evaporation tank needs to be enlarged, and new pipes need to be added..." Chen Xin said to the commissar, "get two air-conditioning compressors, and then get some steel pipes and iron sheets. These things should be enough."


    As soon as Chen Xin''s voice fell, the political commissar wanted to turn around and prepare the materials, but Chen Xin suddenly stopped him.


    As if he remembered something, he patted his head and said to the commissar, "send someone else to the Polytechnic to inform the people of the scientific research institutions, tell them I''m here, and ask them to send someone over."


    "All right, I''ll arrange it now!" When the political commissar saw Chen Xin finish, he confirmed that he had just trotted all the way to arrange what Chen Xin said, while Chen Xin looked at the ground source heat pump in front of him and thought about whether there was a better way to improve heating.


    While Chen Xin was thinking about the renovation of the ground source heat pump, uncle Ding also reported to the director about the renovation of the boiler. After getting permission, he went back to the special police team and found Chen Xin.


    "The director has agreed to reform the boiler. Chen Xin, how do you plan to reform it? How long does it take for the transformation, and does the boiler need to be shut down? " Uncle Ding finds Chen Xin, but he is not polite. He directly asks Chen Xin what he is most concerned about.


    Chen Xin thought about it and said, "I''ll see the boiler first."


    "Well, I''ll have you checked the boiler." Uncle Ding nodded and agreed directly.


    led to the boiler room of the shelter of the municipal police station, Chen Xin went to the working boiler, listened to the roar of the burning flame in the boiler, felt the heat wave from the boiler, and nodded clearly.


    "Can change, do not need to shut down." Chen Xin turned his head and looked at Uncle Ding, who came with him. He answered his previous question: "but the transformation needs a lot of things. I''ll make a list later. With all the relevant materials ready, we can start the transformation."


    Hearing what Chen Xin said, uncle Ding felt relieved.


    How to improve the heating in this extremely cold weather is a problem that plagues all the refuges in the urban area. If Chen Xin can solve this problem, even if it is only temporarily solved, it can save many people''s lives, which is a great good thing to let go of the big stone in his heart.


    And uncle Ding, who was relieved, hastened to urge Chen Xin to list out the materials needed for the transformation.


    Chen Xin promised that he didn''t take a close look around the boiler. For the system, it''s enough to see the boiler.


    The coal-fired boiler used in the medium-sized shelters in the urban area is a layer fired boiler, which has the advantages of less auxiliary equipment, simple manufacture and installation, easy operation, and is suitable for small and medium-sized boilers.


    However, because the combustion mode is to lay coal blocks on the chain grate for layered combustion, it will have the disadvantages of incomplete combustion and high combustible content in slag and fly ash. Generally, the efficiency of the boiler can only reach 75-85%. In fact, there is a lot of room for transformation.


    Of course, this room for reform is for Chen Xin, who owns the system, because he can completely change the combustion mode of the boiler without shutting down or dismantling the boiler equipment, and transform it from the inefficient layer combustion type to the more efficient chamber combustion type or cyclone type.


    The difference between these two boilers and layer combustion boiler lies in the combustion mode, because both of them use the way of completely crushing coal into pulverized coal and then fully burning to carry out coal combustion. Therefore, both the degree of full combustion and the boiler efficiency are much higher than that of layer combustion.However, the chamber combustion boiler needs more supporting equipment than the layer combustion boiler because it needs to screen, crush and grind the raw coal into most of the pulverized coal with particle size less than 0.1 mm, and then blow it into the furnace through the burner for suspended combustion.


    This kind of boiler is obviously not suitable for small and medium-sized shelters, but because the room fired boiler can do a lot, it is more suitable for large shelters.


    Therefore, Chen Xin did not choose the chamber combustion furnace as the transformation direction, but chose the cyclone furnace.


    Some of the boilers with this combustion mode are between the layer combustion furnace and the chamber combustion furnace. The pulverized coal particles or coarse pulverized coal with particle size less than 10 mm are first whirlwind combusted through the front mounted cyclone to produce high-temperature flue gas, and then enter the main furnace for radiation heat exchange, so as to fully burn the coal and release heat.


    Compared with the chamber combustion furnace, the cyclone furnace can also be very small, so it is very suitable to be used as the transformation direction.


    The only problem is that the applicable coal type of cyclone furnace is limited by ash melting point and slag viscosity, and the boiler load variation range is small, so it can not start and stop quickly.


    And because the temperature in the furnace can reach about 2000 ¡æ, the harmful gas NOx emission is large and the air pollution is serious.


    But now it''s the end of the cold, and the boilers are running nonstop. And now the sky is like this, air pollution and other things can only be put back a little, so that human beings can get through this disaster first and survive.

 Chapter 290

    A few hours after Chen Xin arrived at the shelter of the city police station, people from scientific research institutions finally got the news and rushed to him.


    Before they met Chen Xin, these researchers were still thinking about how Chen Xin got to the city through the snowstorm. But after they saw the power armor that Chen Xin had parked in the special police team, all their doubts were thrown out of the air and turned into a frenzy. They were eager to take it apart immediately.


    Fortunately, Chen Xin stopped them.


    "Just have a look. There will be drawings and prototypes for you later. This one is my own private product, so I won''t give you any research."


    When Chen Xin made exoskeleton protective clothing, the predecessor of power armor, he wanted to give these things to the state for mass production. Naturally, he would not exclude the desire of these researchers to study power armor.


    However, he has to rely on this set of power armor to return to his shelter. In addition, he also plans to keep this set of power armor for himself, so he does not want to give it to scientific researchers for dismantling.


    Although the researchers feel sorry for this, they can still understand Chen Xin''s choice and ignore the power armor. They are also concerned about why Chen Xin suddenly ventured through the snowstorm in this bad weather and came to the urban area.


    "The situation in the urban area is so bad that I want to see what I can do to help." Chen Xin explained to the scientific researchers and explained what he was doing: "now I plan to upgrade the ground source heat pump and coal-fired boiler of the shelter heating system of the municipal police station. I have a little idea about the problems caused by the snowstorm, and I need to discuss with you."


    Hearing Chen Xin say so, the scientific researchers put away their desire to study power armor, and their expressions became serious.


    Because we have lost the ability of weather forecast, this sudden Blizzard is a sudden accident for all of us, which caught us unprepared. No one is prepared for it.


    Although the municipal government has made plans for sudden disasters or emergencies, limited by the existing conditions, there is no plan to deal with the blizzard that lasts for more than a week and the temperature reaches minus 70 degrees.


    As a result, the heating problem has become the most severe test for all shelters and survivors. If they can survive, they will be happy. If they can''t survive, they can just seal the door of the shelter and use it as a graveyard.


    As a matter of fact, this snowstorm has not only affected this city. According to the contact between scientific researchers and higher authorities through internal lines, this snowstorm is blowing from Siberia and has affected most of the central and eastern parts of the country along the way.


    If there are satellite images, you can see that almost half of the territory of the whole country is covered in the raging snowstorm.


    It can be said that this blizzard is not only threatening this city, but also forcing most of the country to a very dangerous life and death line.


    Under such circumstances, any way to improve the current situation is good. As long as the method is effective, it is equivalent to saving more than half of the people in Yanguo.


    "What are you going to do, Mr. Chen Xin? It''s not easy to solve the heating problem in this situation now! " There is no good way for researchers to do this. They really want to know what Chen Xin thinks.


    At present, the main heating methods of various shelters are coal-fired or oil-fired, gas-fired boilers, and electric heating.


    Oil fired and gas-fired boilers are mainly the original boilers before the disaster, but considering the tight supply of oil and natural gas, the use of these oil-fired and gas-fired boilers is very problematic.


    Although coal-fired boiler is no better than oil-fired boiler and gas-fired boiler in efficiency and environmental protection, coal-fired supply is relatively simple and low cost, which is also the most common heating method at present.


    As for electric heating, it mainly exists in small shelters and private shelters. After all, such small shelters, even the smallest boilers, are very wasteful and unnecessary under normal circumstances.


    After all, if small shelters and private shelters burn boilers, they will not be able to effectively use all the heat energy output from the boilers, which will be wasted to a large extent.


    Even in this case, the boiler is still a waste for small shelters, and can not play a good heating effect.


    As for the large shelters, not to mention, the boilers are almost overloaded, and they can''t raise the temperature above zero.


    Some people may talk about the polar scientific research station, but the problem is that although the polar scientific research station also uses these methods for heating, the cold protection and heat preservation measures of the polar scientific research station are not comparable to these shelters.


    Far more space than a few houses in the polar scientific research station, and the inevitable loss of heat due to the need for air circulation, lead to the temperature can not rise.


    In order to solve this problem, in addition to avoiding heat loss, the simplest way is to provide more heat, but this point goes back to the origin, so it is necessary to improve the boiler or have a new heating method.


    In fact, researchers have been working hard in this area, but they really can''t think of a better way.In fact, it''s not difficult to transform the boiler or electric heating, but the problem is that the boiler needs to be shut down by conventional means, and then the whole boiler needs to be disassembled for transformation. Regardless of the transformation cost, just stopping the transformation period of the boiler is enough to freeze all the people in the refuge into old popsicles, which will not revive.


    Chen Xin said that he had an idea, which naturally made the scientific researchers overjoyed. They had great expectations for Chen Xin, who had been working miracles in their eyes.


    "The main problem of heating is lack of heat. I can not stop the boiler to improve the combustion efficiency and heat efficiency, but the improvement is limited, so I still need a new way of heating." Chen Xin sorted out his ideas, thought about it and said: "electric heating is a good supplement. On the one hand, some shelters do not have electric heating equipment. On the other hand, it is the output of electric energy. After all, coal is also used in power plants, and the electricity generated is actually heat energy. It is better to directly burn coal for heating after another transformation.


    So I plan to transform the isotope thermoelectric battery that I made before, and try to make an isotope generator. After installing one in the shelter, it will be connected to the circuit of the shelter. In this way, with enough electric energy, we can use electric heating to make up for the lack of heating. "


    Hearing Chen Xin say so, the researchers are shocked, but they really don''t know what kind of expression they should show.


    The isotope generator, which is only in science fiction, is beyond their imagination.

 Chapter 291

    "Mr. Chen Xin, by isotope generator, do you mean radioisotope generator?" When a researcher heard that Chen Xin mentioned isotope generator, he naturally thought of radioisotope generator which is no different from isotope thermoelectric battery.


    The so-called radioisotope generator is a generator that uses the heat energy released by isotope decay to generate electricity. From principle to structure, it is no different from the radioisotope thermoelectric battery. As for the power generation capacity, it is about one hundred watts. Compared with the radioisotope thermoelectric battery made by Chen Xin, which can reach more than one hundred kilowatts, it is more than one thousand times in the true sense There is a big gap.


    As soon as the researcher said that, he reflected that there was something wrong with what he said. Chen Xin was able to make isotope thermoelectric batteries with power generation capacity of more than 100 kW. How could the isotope generator he said be just as simple as the radioisotope generator?


    Sure enough, Chen Xin shook his head and said, "no, I''m not talking about isotope generators, but isotope fusion generators. Some of them are similar to the principle of isotope thermoelectric battery I gave you to study. They use some means to accelerate isotope decay and release more radiation energy to generate electricity."


    "Sounds like an isotope thermoelectric battery in parallel, and then used as a generator?" Chen Xin''s explanation made these researchers quickly understand what he said about the isotope generator.


    "It''s about the same, but in terms of generating capacity, it''s more powerful." Chen Xin nodded and continued to explain: "although the decay rate of isotope thermoelectric cells has been accelerated, the reaction rate is still relatively flat, so a battery can last for ten years.


    But the isotope generator is different. If the fission reaction is going on, the isotope charge in it may have to be replaced in a year, but in exchange for a strong power output, it can be used as a generator. "


    "Is that so? If there is enough electricity, there will be more electricity for heating in each shelter, and a large amount of coal will not need to be used for power generation, but can be directly used for heating! " The researchers understood Chen Xin''s idea and supported it.


    Chen Xin also nodded. In fact, he has more ideas, but in the current situation, he said that this is the fastest way to get results.


    In fact, if conditions permit, he would like to build a device similar to the energy tower in the ice age, which can directly disperse the cold of the whole city, rather than the installation of generators in a shelter.


    "So I''d like you to help me raise some materials. I used to make isotope temperature difference batteries. First I made isotope batteries, and then I transformed them into generators. Each shelter can be equipped with one to ensure all the power consumption. The maintenance only needs to replace the batteries once a year." Chen Xin told the researchers his requirements.


    In addition to leaving one person to help Chen Xin, the researchers quickly left and went back to prepare materials according to Chen Xin''s requirements.


    Chen Xin needs to transform the ground source heat pump of the special police force first. While he is waiting for scientific researchers, the political commissar has collected all the materials needed for the transformation.


    When he heard that Chen Xin was going to transform the ground source heat pump, the researchers who stayed to help him were very excited. He had heard about Chen Xin''s ability for a long time, and was able to see Chen Xin demonstrate his ability with his own eyes. Even if it was just to transform the ground source heat pump, he was still excited.


    Chen Xin didn''t feel much about this. After the commissar sent the materials, he plunged into the room where the ground source heat pump was installed, opened the upgrade interface of the system, and was ready to start the upgrade.


    "Mr. Chen Xin, is there anything I can do for you?" Seeing that Chen Xin was ready to work, the researchers asked him if there was any place where they could get involved.


    Chen Xin was stunned when he heard this question. Then he responded and shook his head and said, "don''t use it for the time being. I''ll do it myself."


    With that, Chen Xin directly chose to upgrade these ground source heat pumps installed by the special police force on the system interface.


    After Chen Xin''s upgrading, the single ground source heat pump originally installed here is integrated under the action of the system. After absorbing the upgrading materials, it becomes a large-scale equipment. Although there are sub units, it is a complete whole.


    In Chen Xin''s eyes, the power of the upgraded ground source heat pump has increased by nearly 50%, and the heat dissipation efficiency of the matching heating pipeline has also increased by 30%, and it has been upgraded from water heating to air heating. It can be said that this upgrade has greatly improved the heating of the special police force.


    After Chen Xin finished the upgrade, the system also prompted that the single 5000 point deposit and daily 50 point survival increased as before.


    This was a surprise. Chen Xin didn''t respond. Before his transformation, he forgot that he could gain survival.


    However, this is also good. This single 5000 point survival income is enough for him to recover the investment he just put in and earn more.


    While Chen XinPan was lighting up his harvest, the researchers on one side were in a daze. He was still shocked by what he had "seen".Affected by the system, in the eyes of this researcher, Chen Xin combined several separate ground source heat pumps with his own efforts and transformed them into a complete whole. Not to mention, he did this in the operation of the equipment, which really opened his eyes.


    "Is this your ability, Mr. Chen Xin? That''s amazing The researchers sincerely praised it.


    Hearing the voice of the scientific researchers, Chen Xin looked back at him and recalled the scene when he saw his Upgraded items last time. He just said with a smile, "these ground source heat pumps are all made by me before. It''s relatively simple to transform them. It''s nothing."


    "That''s very powerful. Is this equipment connected to their heating line? Can we improve the heating here? " With curiosity and exploration, the researchers asked Chen Xin.


    "The power has been increased by 50% compared with before, and the heating mode has been changed from water heating to air heating, which should be able to improve the heating situation here." Chen Xin explained his transformation effect to the scientific researchers a little, but he didn''t say much. On the contrary, he said he didn''t understand the technology setting.


    "That''s great. It''s good for the shelter now, even if it can increase the heating effect by 1%." The researchers praised it sincerely.

 Chapter 292

    When Chen Xin and his researchers left the room where the ground source heat pump was installed and came to the canteen of the special police force, the heating effect of the ground source heat pump was obviously improved after the transformation. Although the temperature is still cold, the temperature in the room has increased significantly.


    Before Chen Xin''s renovation of the ground source heat pump, people here wanted to stick it on the radiator, but now they have changed from water heating to air heating. These people are just around the radiator, and obviously they can feel comfortable.


    In fact, it''s easy to understand that water heating is to heat water through a boiler or heat source. The temperature is generally about 60 ~ 80 ¡æ, which can be held directly by hand without feeling very hot.


    But gas heating is to heat the water into high-temperature steam through the heat source. When the temperature is above 100 ¡æ, it can scald people.


    Although both of them are heating, the gap in heating efficiency can be said to be very different.


    For the heating system, if there is no enough surplus heat source, there is no way to use air heating.


    However, for now, only the SWAT team can enjoy the air heating in the whole refuge of the city police station. After all, the whole refuge uses water heating, and the air heating and water heating can not operate at the same time. So just now, when Chen Xin was upgrading, he only transformed the heating system connected with the ground source heat pump in the area where the SWAT team is located into air heating system Warm.


    If we want to transform the heating of the whole city police shelter into air heating, we can only wait for Chen Xin to transform the boiler of the shelter.


    For this, Chen Xin is not worried at all, because it is really no trouble at all. The only thing he has to wait for is for the municipal police station to collect all the raw materials for the boiler transformation.


    So at this time, Chen Xin''s look is much more relaxed than before. When he finds Qin LAN and Ding Ning in the canteen, his face is also smiling.


    "Xiao Ding, a LAN!" Chen Xinchong greets them and walks to them. The researcher beside him walks to one side with great insight, without disturbing Chen Xin and his friends.


    "Ah Xin! Sister Lan said that you just went to do the transformation of the ground source heat pump. What''s the situation now? " Ding Ning is very happy to see Chen Xin''s performance. While warmly greeting him, he also inquires with concern.


    "The upgrade has been completed. Don''t you feel the temperature of the heating system rising now?" Chen Xinchong Ding Ning smiles for a while, explains one sentence and then asks her, "Xiao Ding, do you live here recently? Do you know what''s going on in the dragon lady''s house? "


    For this problem, Ding Ning shook his head in embarrassment and explained: "when the blizzard came, I was on duty here and began to go back once, but later there was no time to go back. That place should have been buried by the blizzard now."


    At this point, the expression on Ding Ning''s face was a little embarrassed. When Mo Qingyan handed over the house to her before, she asked her to take care of it. Now the house is buried in snow. Although it''s due to the weather and irresistible manpower, it''s true that she didn''t take care of it.


    Hearing Ding Ning say so, Chen Xin nodded clearly, this situation he obviously expected, so he said to Ding Ning: "when I came here, long Niang also talked to me. I''ll go back and have a look. It''s her home. Although she has moved to my home now, her home still can''t give up."


    "Well, ah Xin, tell me when you go. If I have time, I''ll go with you. I still have my things there." Ding Ning thought of what he didn''t have time to bring out and said a word to Chen Xin.


    Chen Xin nodded and took a look at the canteen. He asked Ding Ning and Qin LAN, "can I get something to eat here? I''m a little hungry. Are you hungry, Alain


    "A little bit, but there are too many people here. We''d better eat our own food." Qin Lan also took a look at the canteen, and saw the long line at the dining window. She and Chen Xin had emergency food in their power armor, so there was no need to squeeze with these survivors here.


    Chen Xin also nodded to agree, so he asked Ding Ning: "Xiao Ding, does a LAN''s room still exist? Or do you know where we can get something to eat? "


    "Sister Lan''s room is still reserved. You can go there directly." Ding Ning looks at Chen Xin and Qin LAN enviously.


    In fact, she is already very hungry, especially when she is on duty in the canteen. She is more likely to be hungry when she smells the food.


    But the responsibility is that no matter how hungry she is, she must stick to her post before she can have a rest, instead of getting something to eat just because she is hungry.


    Chen Xin and Qin LAN didn''t say much. After saying goodbye to Ding Ning, they went out to the canteen together.


    Seeing Chen Xin and Qin LAN walking out, the researchers on one side immediately pasted up and asked Chen Xin, "Mr. Chen Xin, what are you going to do?"


    "I''m going to have a rest and eat. I came out in a hurry in the morning. After I came here, I was busy. I was a little hungry. " Chen Xin answered, looking at the scientific research personnel thought for a while, said: "you also go to eat something, don''t always follow me."The researcher quickly shook his head and said, "no, no, we had lunch before we came here. I''d better follow Mr. Chen Xin. It''s very enlightening for me to see Mr. Chen Xin transform your equipment."


    Chen Xin knows that the concept of information state of the system is vague, which can instill a lot of knowledge and pictures into people who see the upgrading process in an instant. The more knowledge people have, the more instillation they can get. It''s not surprising what the scientific researchers said, so he nodded and acquiesced to the other party''s following their own things.


    However, Chen Xin went to restart the power armor he had parked before. After wearing the power armor and Qin LAN came to the room before her, he took off the power armor with Qin LAN and walked into the room together.


    The room seems to be the same as before, but Qin Lan was away for more than a month, and a thin layer of ash fell on the table.


    Qin LAN finds out the rag and wipes the table and chair. Then she asks Chen Xin to sit down. However, the researchers who are with them do not come in. Instead, they are obsessed with looking at the power armor that Chen Xin and Qin LAN stop at the door, looking like they want to study.


    Chen Xin doesn''t care about this either. He and Qin LAN just take out the emergency food from the silo behind the power armor and eat it.

 Chapter 293

    It involves the survival of all the survivors in the shelter. The reconstruction of the boiler in the shelter is advancing rapidly. Although Chen Xin needs a lot of materials, the underground road between the shelters is still unblocked. After some time of mobilization, the materials he needs have been transported to the shelter of the city police station.


    "Comrade Chen Xin, the materials you need have arrived. When do you think we can start the transformation of the boiler?" The commissar finds Chen Xin who is eating in Qin Lan''s room. Although he feels embarrassed to disturb Chen Xin''s meal, he still asks Chen Xin about it.


    During the period when Chen Xin was eating, because Chen Xin upgraded the ground source heat pump and heating, the temperature of the whole area has risen up, about 78 degrees from the original minus 10 degrees, and the temperature is still rising, which is expected to break through zero.


    And because the heat generated after the transformation of the ground source heat pump is more than before, the bathrooms that rely on the ground source heat pump to supply hot water also have more hot water, which can be opened for a longer time, so that more people can take a hot bath.


    This is very important for the SWAT team and even the whole city police shelter. After all, what most frostbite patients need most is not medicine, but hot water.


    Therefore, in the view of the top management of the city police station, if the boiler of the shelter can be transformed like the ground source heat pump of the special police force, so that it can improve the heating efficiency and output more heat, it is undoubtedly the most important thing at present.


    Because of this reason, commissar Ming knew that Chen Xin and Qin LAN were having dinner, so he found Chen Xin for the first time. He hoped that he could go to reform the boiler as soon as possible.


    Naturally, Chen Xin also knew the importance of this matter, so when he saw the political commissar coming to him, he didn''t show the meaning of shirking responsibility. After finishing his lunch, he followed the political commissar to the boiler room he had been to once before.


    And Qin LAN sees this, also hastened to follow up.


    However, the researchers who have been standing at the door of Qin Lan''s room just now to study the two power armors are a little tangled. On the one hand, he wants to see how Chen Xin upgrades the boiler in work, on the other hand, he is reluctant to see the two power armors in front of him.


    He had been fascinated by these two power armours for more than ten minutes. He wanted to sit up and drive them, or even take them apart to have a look.


    However, he still remembers that Chen Xin made the two power armor in front of him, and he also promised that he would provide the prototype to his department for research, so the researcher quickly adjusted his mind and caught up with Chen Xin, and this time he also prepared the camera in his pocket.


    Before Chen Xin upgraded the ground source heat pump, he had not had time to take out the camera. Chen Xin was finished, which made him very regretful. This time, he prepared the camera in advance and decided to record the whole transformation process of Chen Xin.


    The party came to the boiler room, where Chen Xinyao''s materials had been piled up. Because there was coal in the boiler room, Chen Xinyao''s materials were quite a lot, which seemed very crowded for a moment.


    Chen Xin didn''t mind. He went to the boiler and was ready to upgrade.


    Seeing this, the researchers immediately approached Chen Xin with a camera, stood behind him, selected a position to start shooting.


    Chen Xin didn''t mind each other''s shooting. Seeing that everyone looked forward to him, Chen Xin directly used the system upgrade function for the boiler.


    It is still a flash of green light. Even the structure and style of the whole boiler have changed greatly in the green light, from the original layer burning furnace to the cyclone furnace, and the volume, structure and ancillary equipment have changed greatly. It can be said that after the green light swept, the whole boiler room has completely changed.


    But the boiler itself is still burning, and because of the different combustion methods of the cyclone furnace, it makes a more violent whistling sound, as if there is a fire dragon whistling in the furnace.


    Everyone doesn''t mind the whistling sound coming from the furnace of the boiler. The louder the sound and the more vigorous the combustion, it means that the boiler can generate more heat. This is the most important thing for the present shelter.


    However, after taking a picture of Chen Xin''s upgrade, the researchers came to Chen Xin and asked him, "Mr. Chen Xin, the structure of this cyclone furnace is a little different from the common horizontal cyclone furnace, isn''t it?"


    For this problem, Chen Xin, who upgraded the boiler, was very confused. He shook his head and explained, "I''m not sure about this. I just think this structure is better to use and more in line with the current needs."


    After hearing Chen Xin''s answer, the researchers felt helpless. He had already known about Chen Xin''s transformation and upgrading, regardless of the explanation of the principles and ideas. But for the researchers, when they see something, they can''t understand its design ideas and principles. This is undoubtedly painful.


    In particular, you can only explore all the things by yourself, but you still don''t know what makes it.


    In the eyes of scientific researchers, the cyclone furnace is not a common horizontal cyclone furnace, because the combustion form of the cyclone furnace increases the volume of the furnace. Theoretically, the volume of the cyclone furnace under the same conditions is smaller than that of the layer burning furnace. But now the boiler in front of us not only increases in volume, but also has a structure obviously different from that of the common cyclone furnace. How can we not let the scientific researchers ignite it The desire to explore?Fortunately, after hesitating for a while, Chen Xin explained: "I have made some adjustments to the structure of the boiler. Now the pipes of the heating system are connected to the boiler, and the water is directly heated into steam by the boiler and fed into the heating pipe to heat the whole refuge.


    The original water heating has no effect at this temperature, but the air heating efficiency is higher and the temperature can rise more. "


    "The effect of air heating is better than that of water heating, but why is the transformation of this pipeline connected in this structural form?" The researchers pointed to the heating pipeline connected to the boiler and were full of doubts, but it was obvious that Chen Xin would not explain these to him.


    Fortunately, he also knew that Chen Xin would not explain to him, so he squatted beside the steaming boiler, took the camera and looked at what he had recorded over and over again, frowning and thinking about why the boiler in front of him had to be so transformed.


    Chen Xin can''t help but turn around and leave with Qin LAN.


    Instead, the political commissar and several leaders of the Municipal Bureau are busy thanking Chen Xin. Chen Xin''s move this time can really be said to have saved all the people in this refuge.

 Chapter 294

    After rebuilding the boiler in the shelter of the city police station, Chen Xin and Qin LAN return to Qin Lan''s room again.


    It has to be said that after the transformation of the boiler heating effect has been completely different, at least Chen Xin and Qin LAN sitting in the room, has obviously felt the temperature rise, and the frost on the wall is slowly receding.


    "It seems that the temperature has gone up to zero." Qin LAN looked at the receding frost on the wall and looked at Chen Xin: "the people in the shelter should be much better now?"


    "At least it''s more comfortable than ten degrees below zero. At least it''s not so easy to get frostbite when it''s above zero." Chen Xin specially took a thermometer and took a look. The room temperature really rose to 1 ¡æ, which made him smile.


    This time, although the transformation of the boiler and the ground source heat pump made Chen Xin gain two survival points, which add up to a total of 10000 survival points and an increase of 100 survival points every day, Chen Xin also invested 11000 survival points in these two transformations.


    And this is the result of Chen Xin''s letting people from the police station gather the materials.


    The transformation of large-scale equipment requires a lot of investment. Even if Chen Xin can get more than 400 survival points every day, it will only be more than 12000 in a month. With his previous accumulation, Chen Xin''s survival point is still enough for him to transform four boilers.


    Of course, this means that Chen Xin can only rebuild four more boilers when he has no income. Taking into account the 5000 survival points that can be harvested after the reconstruction of each refuge, Chen Xin can actually rebuild all the boilers in the city''s refuges.


    However, this requires the full cooperation of the municipal government. Otherwise, without materials, it will cost ten times more to survive. For Chen Xin, he can''t afford to transform a boiler.


    And before that, it is still scientific research institutions that find Chen Xin first.


    They are already mobilizing materials according to Chen Xin''s requirements, but it takes time for them to do so. However, these researchers can''t help but want to understand what Chen Xin said about isotope generators.


    In the face of these researchers can''t wait, Chen Xin hesitated for a while, and after a little consideration, he and Qin LAN returned to their research institutions in the city with two power armored vehicles and researchers.


    It is said that it is a scientific research institution, but in fact it just occupies a laboratory in the Institute of technology. In fact, it is just a transit station.


    After all, their main task is not to carry out research, but to send Chen Xin''s upgraded projects collected by the superior special team from the national scientific research institutions to Chen Xin according to the priority and materials after receiving them, and then take back the finished products of Chen Xin''s upgraded projects and send them back to the original institutions for reverse cracking.


    So for this scientific research institution, they are just like a transshipment warehouse, but they can''t let people who do logistics and warehousing take charge of these things.


    Because all the project samples that can be sent here can be called high-end products. Many things can''t even be touched compared with the most expensive porcelain. In addition, they have to classify and prioritize. Many things can''t be done without professionals.


    This leads to a group of serious researchers working as porters.


    However, these researchers themselves are quite indifferent. Having seen Chen Xinna''s completely unscientific upgrading ability, they also know how important their work is, and they have to deal with these project samples carefully. They don''t mind that they are just a warehouse porter.


    Just because the researchers themselves don''t mind, it doesn''t mean that no one here has any opinions.


    At least when Chen Xin and Qin LAN follow the researchers to their laboratory in the refuge of the Institute of technology, a young researcher passing by is very angry with Chen Xin. He hums at him and goes around without saying hello, just like Chen Xin is something dirty.


    This makes Chen Xin feel puzzled, while the researchers on one side are particularly embarrassed.


    Chen Xin asked them a question, but these researchers were embarrassed to explain it.


    Although Chen Xin''s ability is really against the sky, especially in this last age, Chen Xin''s ability can be said to save a lot of research funds and research time, and enable many important research projects under study to be quickly transformed into finished products, which is of great strategic significance for the whole country.


    But Chen Xin''s ability is very unscientific. It is clear that all the processes are made by him, but he can''t explain the truth and principle, and even has no design ideas. This makes Chen Xin a typical pseudo science and civil science swindler in the eyes of many academic or orthodox researchers.


    In the eyes of these people, the state should not spend a cent on Chen Xin, who cheated the world and stole his fame, and who didn''t know how to cheat the state, let alone waste resources on him.


    These resources should be used in more useful places, such as their research projects.


    The young researcher just now is actually such an academic figure. His tutors are orthodox scientific researchers with some achievements. They always look down on folk figures like Chen Xin.After listening to the explanation of the scientific researchers, Chen Xin can only shake his head helplessly. In a sense, his ability is really a liar, because he does not have any knowledge and ability, and everything depends on the system.


    Upgrading depends on the function of the system, not on his own ability. In a sense, Chen Xin is really cheating.


    But what he can provide is real, and all the upgrades are visible. Only when they have real effects will the state be willing to set up a special team for him to deploy national resources to serve this matter.


    It''s just that the level of national strategy is too high, and Chen Xin''s ability is too important for the country. The "truth" of this matter has been blocked. Although the researchers in the Institute of technology can understand that the establishment of this scientific research institution here is due to Chen Xin, a private figure, it is difficult to understand Chen Xin''s real ability.


    Therefore, this undoubtedly gives these people who do not understand the situation an illusion, that is, Chen Xin is very much like a liar who swindles the national resources.


    "Well, let him do this kind of thing. We can do our own thing well." In the face of this situation, Chen Xin can only be helpless. After all, he has no way to explain one by one. He can only say that he can do his own thing well. In the end, he will be clear and turbid.

 Chapter 295

    In the laboratory, researchers sit around Chen Xin and look at him with expectation.


    Although these researchers all know Chen Xin''s existence and ability, there are still a few who have actually met him. It is very exciting for these researchers who have been famous for a long time to invite Chen Xin to them.


    In particular, Chen Xin also said that he would build an isotope generator, which made these researchers even more excited.


    Isotope generator is also a kind of nuclear power. However, according to Chen Xin, it obviously belongs to the category of small or even micro nuclear power, and it is different from the experimental technology of radioisotope generator under power. Because Chen Xin has the endorsement of isotope thermoelectric battery, the isotope generator he can take out can be put into practice The technology used.


    This is very important and worth looking forward to for Yanguo, because the main energy technologies that can still be applied on a large scale are thermal power generation and nuclear power.


    Solar energy has been unable to use because of the lack of light, hydropower has been stopped because of the freezing of rivers, and wind power can not be used because of the excessive wind. In this case, small and micro nuclear power, which is stable and clean, and does not need too much investment, and also covers a small area, is very worthy of promotion and application.


    If it were not for the high requirements for the construction and application of small nuclear reactors and nuclear power plants, Yanguo''s senior management may not have no plan to promote nuclear power on a large scale.


    Now, the isotope generator proposed by Chen Xin obviously provides a pillow for the high-level sleepiness of Yanguo. As long as Chen Xin can make the isotope generator he said and reverse crack the technology, the high-level of Yanguo will surely popularize it on a large scale.


    "As for the isotope generator, its structure should be a triangular column shape. The part on which the battery is installed can quickly dismantle and replace the battery inside. The battery is the isotope temperature difference battery I provided before. How about your reverse cracking technology?" Chen Xin introduced the isotope generator he wanted to make to these researchers, and specially drew a schematic diagram on a white board.


    As for the isotope thermoelectric battery, after Chen Xin submitted it to the state, the senior management attached great importance to it and dispatched the most capable experts and scholars in China to carry out reverse research. These researchers, as project related personnel, also knew about these things.


    So after Chen Xin asked, he quickly answered: "the reverse technology of isotope thermoelectric battery is progressing smoothly. However, because there are too many technical problems to be solved, the project team has only successfully trial produced a 10kW power experimental prototype, which is still a certain distance from manufacturing an engineering prototype and putting it into practice."


    Chen Xin can''t help but frown when he hears what the researchers say. He didn''t expect that he had already provided the finished product, and the country still had many difficulties in reverse cracking.


    So Chen Xin continued to ask the researchers, "what are the limitations? Is there anything I can help you with? "


    "This..." After the researchers looked at each other, one of them replied to Chen Xin: "it''s mainly about the overall industrial strength. Many things can be processed in the laboratory, but if mass production is needed..."


    "Now the national industrial facilities have been seriously hit. Many important large-scale industrial equipment have been seriously damaged in the previous disaster because of their huge volume and inconvenient handling. At present, the country has only some industrial facilities preserved before the disaster, so there are some problems in the processing of some materials and the manufacturing of parts." Another researcher immediately took over the conversation and continued to say to Chen Xin: "although the country is steadily recovering its industrial strength according to the plan before the disaster, it still takes time. Moreover, some parts and industrial raw materials that originally needed to be imported are now out of supply. We can only find available substitutes ourselves, which also brings great trouble to industrial production."


    When Chen Xin heard what the researchers said, he could only nod heavily. This kind of thing can not be improved by himself.


    The promotion of a country''s industrial strength needs improvement and development in all aspects. It needs a strong country and a strong comprehensive national strength as support, which is the embodiment of a country''s real strength.


    This can not be achieved by upgrading one or two equipment or projects. What it needs to upgrade is all the things involved, from a screw to a nuclear power plant.


    "If so, doesn''t it mean that the isotope generator can only be manufactured by me?" Chen Xin felt his chin and frowned.


    "It''s very likely that this is the case, and if the supply of isotope thermoelectric batteries can''t keep up, there will be problems in the application of isotope generators." A researcher answered with some expectation.


    If the state can''t manufacture isotope thermoelectric batteries, the promotion of isotope generators will be meaningless, because without batteries, isotope generators will be an empty shelf, which obviously can''t be done.


    After serious consideration, Chen Xin asked the researchers, "is it feasible to build a production line that can produce isotope thermoelectric batteries?""This..." Several researchers looked at each other, looked at each other, and then replied, "of course, it''s feasible, but the matching of parts and materials..."


    "Then the raw material processing and parts manufacturing are also included in the production line!" Chen Xin knows what he is talking about. If it was before the disaster, no one would have built such a production line. No one would have built a complete set of supporting facilities for such a product, from raw materials to parts, just because he wanted to make a product.


    In general, the supporting facilities are built after the relevant projects are put into construction, and most of the parts will be imported from other places, so a complete system will not be built at one time.


    However, for Chen Xin, it is not impossible to grasp the ultimate killer of the system.


    "Is that really OK?" The researchers still can''t believe it.


    Chen Xin replied without hesitation: "of course, I can go back and study it carefully to see what supporting facilities are needed. By then, directly establishing such a production line can also solve some employment problems and pave the way for the promotion of isotope generators in the future."


    Seeing that Chen Xin had made up his mind, the researchers could not say anything more. They could only prepare to report the matter to the special group at the higher level immediately.

 Chapter 296

    "Can you reach other places now?" Hearing that the scientific researchers said that they needed to report the production line of isotope generator and isotope thermoelectric battery to the special team at a higher level, Chen Xin couldn''t help but wonder how they would contact each other.


    To this question, the scientific researchers answered Chen Xin in detail: "at present, our main means of communication with the outside world are still relying on telephone lines and national defense optical cables. These are national communication networks that existed before the disaster, in order to meet the communication needs after the failure of satellites.


    As for the communication base station that we planned to set up before and the communication network between cities, the project was delayed due to the impact of the snowstorm, and it may not continue until the snowstorm subsides. "


    Chen Xin nodded clearly, but asked another question: "what about radio communication?"


    "Radio communication basically can''t be used. The interference of the snowstorm is too serious. Even if we can get in touch, the signal is intermittent and can''t communicate effectively at all." Scientific researchers also feel helpless about this. Now that satellite communication is not available, in addition to wired telephone and national defense optical cable, radio is the only communication means that is relatively easy to use.


    However, none of these communication methods can be used at will. The national defense optical cable is related to national defense and belongs to military facilities. Under normal circumstances, it is not open to the public. Although the wired telephone can be used for civil use, the bandwidth of the wired telephone is also limited, and limited by the laying of telephone lines, only the place where the telephone is installed can communicate with each other.


    Radio communication is a good means of communication, but it''s hard to get in touch with others in this snowstorm.


    This is also the reason why scientific research departments and the state tried to build a communication network before. Although this kind of communication network still uses wireless communication, the signal between base stations can still be stable, so that an effective and stable communication network can be built.


    But now the whole country is shrouded in the snowstorm, there is no way to continue construction, has begun to build the communication base station can only be temporarily suspended.


    Because this scientific research institution is involved in important national scientific research projects, telephone lines and national defense optical cables are all connected. When necessary, it can directly contact the higher authorities or even higher levels, and it can also mobilize the army.


    In this case, the scientific research institution is the most powerful department in the city.


    Chen Xin understood the situation and didn''t say anything more. After discussing with Qin LAN, he stayed in this scientific research institution for a while.


    In terms of accommodation, this research institution is quite good. The original Institute of technology, as the only university in the city, has good conditions.


    After being transformed into a refuge, in order to provide logistics support for scientific research personnel and the need for confidentiality of scientific research institutions, although the Polytechnic is one of several medium-sized shelters in the city, the population is not large, which makes the accommodation here the best of many shelters in the city.


    But even so, it''s the same cold here. There''s no Chen Xin in the city police station. After the transformation, the temperature can reach above zero comfort.


    Fortunately, this is not a big problem for Chen Xin. If he puts on power armor, he can ensure that he is not cold. The Institute of technology has its own boilers, which are better than other shelters. If necessary, Chen Xin can completely transform the boilers here.


    In fact, after learning that Chen Xin has transformed the boiler which is the refuge of the police station, and coming to the Institute of technology, the leaders of the Institute of technology are already expecting that he can also transform the boiler of the Institute of technology.


    And the leaders of these polytechnics did come to ask Chen Xin to help transform the boiler.


    Chen Xin didn''t refuse this, but it took time to raise the materials needed for the transformation. Chen Xin didn''t deal with it at the first time.


    However, in addition to the Polytechnic, other shelters also need boiler renovation. After receiving the notification from the municipal police, the municipal government also attaches great importance to this matter.


    Moreover, the municipal government''s idea is different. In addition to reforming the heating boilers in each shelter, they also hope that Chen Xin can help to reform the power generation boilers in the power plant.


    In the view of the municipal government, the heating capacity of the refuges will be improved after the transformation of the heating boilers. Although more coal will be consumed, the consumption of electric heating can be reduced in turn, and this part of coal can be saved. The total consumption of coal has not been greatly improved.


    The boiler transformation of the power plant can further improve the combustion efficiency and thermal efficiency, so that the heat energy contained in coal can be better utilized and the use of coal can be saved.


    Therefore, the municipal government specially sent an official to find Chen Xin and explained the municipal government''s idea in detail, hoping that he could come up with a feasible transformation plan to help the municipal government complete the transformation of heating boilers and power generation boilers in various shelters.


    The request put forward by the municipal government is what Chen Xin intends to do. Both sides have the same idea. Naturally, the matter will be settled soon. As for how to reform and how to implement it, we need to discuss and discuss it carefully.Chen Xin happens to have nothing else to do, and the municipal government is also interested in this matter, so naturally it has plenty of time and energy to discuss it.


    After detailed discussion, the whole transformation plan was finalized. According to calculation, if Chen Xin can complete the transformation of the heating boilers and power generation boilers of all large and medium-sized shelters in the city, the total coal consumption of the city can be reduced by 10%.


    This is already a very satisfactory result, because while saving coal, the heating problem of each shelter can also be solved. Although the external temperature is still maintained at a very low level under the blizzard, the internal temperature of each shelter can at least break through zero, so that the temperature can return to zero, so that a large number of survivors will not freeze Injury or hypothermia.


    And such a transformation is also a very beneficial thing for Chen Xin. The survival he has accumulated may consume a wave, but the subsequent daily survival increase is a continuous income, which is not a loss for Chen Xin.


    So after drawing up the plan, Chen Xin agreed to the requirements of the municipal government, and the municipal government immediately began to actively deploy the materials Chen Xin needed to upgrade the boiler.


    After seeing off the officials from the city government who came to discuss the reconstruction plan, Chen Xin said with a smile to Qin LAN, "now the problems in the urban area can be solved, and the people in other shelters can be much better!"

    In the hospital, Hong Rui rubbed her sour back and sighed that she could finally get off work today.


    In recent days, there are still a lot of patients in the hospital, but compared with the previous few days, there are a lot less patients, mainly from the municipal police station and Polytechnic, as well as the power plant.


    According to the news, Hongrui knows that this is because the heating boilers of the three shelters have been transformed, and the internal temperature has been increased. Naturally, there are not so many people suffering from hypothermia and frostbite.


    This makes Hong Rui feel very envious. She envies that the people in the shelters have heating to bake. It''s not so cold.


    Although the hospital is a key care unit, its heating is the same as that of other shelters, but relatively speaking, the security measures are better. The key wards also have electric heating.


    After all, with the improvement of heating in the three shelters, the shift within the hospital has been shortened from 16 hours to 12 hours, and patients waiting for treatment are no longer crowded in the hospital corridor.


    This also makes Hongrui hope that if the heating in the hospital can also be improved, then a large number of patients with hypothermia and frostbite in the hospital can get more effective treatment and get better faster.


    Thinking about this, Hongrui walked towards her office. During this long period of working overtime, the dark circles on her face were very thick, and her whole face was swollen and looked like she had taken off.


    If this kind of thing is before the disaster, I''m afraid Hongrui has tried every means to reduce her swelling and dark circles, and put a thick makeup on her face to cover it. But now she just walks to her office and wants to have a good sleep.


    However, when Hongrui is walking to the office, she meets Chen Xin who is walking here with a group of people.


    "You are Dr. Hongrui Seeing Hongrui, Chen Xin was stunned and recognized her. He quickly said hello to her: "are you just off work? It looks so hard! "


    "Nothing. The hospital is busy these days. Mr. Chen, where are you going?" Hongrui also responds to Chen Xin, but her eyes notice that one of the people with Chen Xin is the vice president of the hospital, and the other is the leader of the city government she once met.


    This makes Hong Rui wonder what''s wrong with Chen Xin, and he seems to be the leader.


    "Oh, the municipal government is going to transform the heating boiler in your hospital. I''m responsible for the transformation." Chen Xin explained to Hong Rui that he didn''t say much, so he said to Hong Rui, "I''ll go there first. I''ll go back and find Dr. Hong Rui. You can talk about it in detail."


    Seeing this, Hong Rui didn''t delay Chen Xin''s work. After watching him go away from others, she reflected that Chen Xin was talking about reforming the boiler.


    This surprised Hong Rui. She didn''t expect that Chen Xin, whom she met several times, had such ability. From the people around him, Hong Rui can see that Chen Xin is not just an ordinary person. He must have a more important identity. Otherwise, the leader of the city government should be the most important one among those people.


    However, Hong Rui just felt a little curious about it, and she didn''t pay much attention to it. She wanted to have a good sleep now.


    Hong Rui, who returned to her office, was awakened by heat.


    Feeling the rising temperature in the office and the warm feeling on her body, Hongrui rubbed her forehead to wake up, then looked at the thermometer hanging before work, which showed 3 ¡æ.


    "The temperature of the boiler has risen?" Hongrui was a little surprised. Before that, even if the heating in the hospital was better than that in other places, the temperature was only - 7 ¡æ.


    It can be said that all of a sudden the temperature rose by 10 degrees. It''s really rare. No wonder she would wake up from the heat.


    Although not hot to sweat or how, but the body really warm up, or let red Rui feel the obvious difference.


    At least, she doesn''t have to sleep in the office any more. She is also wearing a sweater. She has to cover herself with a quilt, a blanket and an overcoat, so that she can''t breathe to keep warm.


    Taking away her heavy coat and blanket, Hongrui gets up and rubs her face. After looking at the time, she finds that she has only slept for two hours, but it''s almost time for dinner.


    This makes Hong Rui hesitant and hesitant. She doesn''t know whether she should go to eat or lie back in the warm quilt to sleep.


    But eventually appetite conquered doze. Hongrui took a little water to wash her face in front of the wash basin in the office. After waking herself up, she walked to the canteen with some heavy steps.


    These days, even though she is only a psychologist, she is too busy to touch the ground in these days when she is transferred to the emergency department for help. Her feet are swollen and she can''t wear her usual high-heeled shoes. Coupled with the cold weather, she can only change into a pair of fat flat bottomed snow boots.Red Rui with snow boots came to the canteen, looked at the team in front of the window, went to the doctor''s window, and lined up with some expectations.


    The food in the hospital has always been guaranteed. Even if the quality of food in other shelters declines, the food in the hospital is guaranteed. After all, people in the hospital need better food.


    And after the city government used the emergency reserve, the food here in the hospital is more appetizing.


    These days, if not every day after work to eat steaming and delicious nutritious food, I''m afraid Hongrui really can''t hold on to this more than ten hours a day.


    Fortunately, now that the boiler in the hospital has been transformed, she believes that her work will be easier.


    When Hongrui is thinking about this, it''s her turn to have dinner. She comes to the window and orders some dishes with the master Fu who is in charge of cooking. After the master has finished cooking, Hongrui plans to find a place to eat.


    "Dr. Hongrui, come and sit down with us." When Hongrui is looking for a seat with the meal, Chen Xin''s voice suddenly rings, which makes her turn her eyes.


    Chen Xin, the vice president she had met before and the leaders of the municipal government were eating together, and there was just a vacancy beside them.


    Red Rui see this, hesitated to just walk past, sat down on the vacant seat.

 Chapter 298

    After lunch, the leaders of the municipal government and the vice president of the hospital had their own things to do, so they left after leaving with Chen Xin. One of them wanted to go back to the municipal government to report on the transformation of the boiler in the hospital, the other wanted to deal with the daily work of the hospital. They were able to have lunch with Chen Xin because Chen Xin was able to transform the boiler.


    For the leaders to leave, Chen Xin didn''t feel left out or despised. On the contrary, he was not used to the treatment of being surrounded by others.


    Now that all these leaders have left, Chen Xin feels more comfortable.


    "Mr. Chen, do you have anything else to do this afternoon?" After dinner, ready to go back to the office of red Rui looking at Chen Xin, politely asked.


    "There''s nothing to do in the afternoon. I''ll go back later." Chen Xin didn''t mean to go back to his own home, but to his temporary residence in the Institute of technology. But after that, he said to Hong Rui as if he remembered something: "by the way, doctor Hong, the herbal seeds you gave me last time have sprouted and are growing well. Do you need me to deal with them and give them to you?"


    Hearing Chen Xin say so, Hong Rui laughs instead and explains to Chen Xin: "those herbs need to grow for at least three months before they can be used as medicine. They don''t germinate and grow out, and some even need to be planted for more than a year to have enough efficacy, so it''s not urgent.


    But Mr. Chen, it''s really rare for you to remember this. At this time, everyone thinks about how to grow a little more grain. Mr. Chen, it''s really rare for you to help me grow herbs. "


    "Grain should be planted, but herbs should not be lost! All these things can cure diseases and save lives, can''t they? " Chen Xin also laughed, and did not explain the problem.


    If he really only had the 100 square meter greenhouse when he first built the shelter, he would only grow enough food for himself, not to mention help grow herbs. Even if he took vegetables for trading, he would have to carefully calculate and consider everything to ensure his survival.


    But he has enough spare power to help others after getting the system, so he will not grudge that little kindness and help.


    Human nature may be selfish, but also everyone''s heart has a certain kind, when you see others in need of help, it''s not a very boastful or strange thing to give a hand.


    "Anyway, I want to thank Mr. Chen for your help. Not only did you help me grow those herbs, but also you helped to transform the boiler." Hongrui feels that she should thank Chen Xin. Both in public and in private, she has reasons to thank him: "you have improved the heating of the hospital by reforming the boiler, which has helped us a lot. Those patients with frostbite and hypothermia can be treated, and we doctors don''t need to work for more than ten hours a day.


    Even if it''s just for this, both our doctors and those patients should thank you very much. "


    "I don''t care about that. Instead of thanking me, their healthy survival is the best reward for me." Chen Xin didn''t care about Hong Rui''s thanks. For him, if he could die a few less people, he felt that his hard work in this period was not in vain.


    Hearing what Chen Xin said, Hong Rui was surprised to see him, but she nodded and said, "if everyone can think like Mr. Chen Xin, that''s great."


    "I think that''s what most people think, right? I have something else to do, so I''ll go ahead and don''t disturb Dr. Hong''s work. " With that, Chen Xin turned and left.


    Looking at Chen Xin''s back, red Rui''s eyes can''t help flashing for a while, and she can''t help but look at Chen Xin with new eyes.


    After leaving the hospital, Chen Xin returned to the Institute of technology. Although he didn''t do much physical work, his busy morning and running between the two shelters made him feel a little tired and wanted to have a rest.


    Just when Chen Xin was going to go back to the room prepared for him to have a rest, the young researcher Chen Xin had met before, who was dismissive of him, found him and said to Chen Xin in a very strong tone: "Professor, come with me!"


    Then, without waiting for Chen Xin to answer, he plans to take Chen Xin to see the professor he said.


    Before Chen Xin knew what was going on, he was led by the young researcher to the direction of the boiler room.


    Although he was pulled by the young researcher and staggered for a while, Chen Xin quickly stood firm, broke away with his backhand, and then pressed the young researcher.


    "What''s the matter with you? Like a bandit Chen Xin frowned. Although he can understand the idea that these traditional researchers despise him as a folk, it doesn''t mean that he has no temper and can be called around.


    "Let go! How can you be so savage! Let go! I''m breaking my hand The young researcher was held down by Chen Xin''s backhand and immediately cried out. He did not expect that Chen Xin would resist, let alone that Chen Xin would hold him down directly with his backhand.


    The young researcher yelled so loudly that it immediately attracted other people''s attention.


    However, even though he was surrounded by a group of people, Chen Xin still didn''t let go of the young researcher, just pressed him to ask what was going on.Young researchers may feel that they have lost face, or they want to take everything on their own, and they don''t want to involve the professor behind them. They just wring their arms, holding on to Chen Xin and refusing to explain. They just ask him to let go.


    Facing the young researcher''s attitude that he is not afraid of boiling water, Chen Xin can''t help feeling a little annoyed, so he tried harder to make the young researcher cry louder and refuse to let him go.


    Although Chen Xin is evaluated by Qin LAN as lack of physical exercise, she can catch up with the policewoman Hua of the special police force as a girlfriend. The so-called lack of exercise is also compared with Qin LAN, which does not mean that Chen Xin is really weak.


    Compared with these researchers who are in the lab all day and in sub-health, the strength of the two is not a heavyweight at all.


    As a result, although the young researcher wanted to break free, he could not get rid of Chen Xin.


    Just when they were in a stalemate, an old professor who got the news looked at the young researcher who was caught by Chen Xin and asked them, "what''s the matter? I asked you to invite people. Why did you get caught? "


    With that, the professor looked up at Chen Xin. Although he couldn''t help frowning, he said to Chen Xin, "comrade, no matter what happens, can you let go of my students first?"

 Chapter 299

    Under the protection of the old professor, Chen Xin still let go of the young researcher he caught.


    The researcher, who was released by Chen Xin, rushed to the old professor and complained to him with resentful eyes: "Professor, this is the liar! This man is so savage. When I say you want to see him, he wrists my arm and won''t let me go! "


    Hearing what his students said, the old professor did not have a preconception, but confirmed to Chen Xin: "is this the case? My student came to ask you to come over, and you twisted his arm? "


    "It''s about the same in general, but he left out a little detail." Chen Xinjian, an old professor, didn''t seem to be unreasonable, and he didn''t lose his temper. So he calmly explained to him, "as soon as I came back from the outside, you rushed over and said in a very strong tone," professor wants to see you, come with me. "He also held my arm. If I didn''t exercise, I would be pulled down by him.


    If you meet such a person with a new professor, will you think about resisting and subduing the other party at the first time


    Hearing Chen Xin''s explanation, the old professor twitched his face, turned around, glared at his students, and scolded him: "I asked you to invite people. Is that how you invited them? What do I usually teach you? "


    Looking at the old professor scolding the young researchers, Chen Xin didn''t say anything and didn''t say much. He just looked at all this blandly.


    However, Chen Xin''s expression was insipid, but the young researcher was very angry. He explained to the old professor, "Professor, this is a liar. Why are you polite to such a person! He must be thinking of something to cheat! Professor, you can''t be fooled by him! "


    When Chen Xin heard this, he was only amused. He had nothing to do with the young researcher, but he was a barbarian and a liar. This made Chen Xin feel especially funny and ironic. He was still a researcher in the Institute of science and technology, and now he is undertaking important scientific research. It is full of absurdity and irony Check.


    Thinking of this, Chen Xin turned his eyes to the old professor and wanted to see how he would deal with it.


    In Chen Xin''s opinion, the old professor may not be a person of great honor and respect to be able to teach such students.


    However, the old professor''s treatment exceeded Chen Xin''s and even everyone''s expectation.


    "I''m sorry, I can''t teach him. As a professor, it''s my dereliction of duty not to teach him how to be a man." The old professor bowed to Chen Xin, apologized sincerely to Chen Xin, and then explained: "before, I really thought that you were the kind of swindler who cheated money with the so-called high-tech concept because of some prejudice, so I had some negative comments on you. These words were heard by my students and had a bad impression on you.


    But today, I have checked the boiler after your transformation, which is indeed a considerable improvement compared with before, which is enough to prove that you are not a liar. I apologize for my previous prejudice.


    Originally, I wanted my students to invite you to come over and discuss the relevant technical issues. I also wanted to formally apologize to you, but I didn''t expect that things would turn out like this and give you trouble. I''m really sorry. "


    "How kind of you, old man! I can understand why you think I''m a movie. I won''t believe this kind of thing. " Chen Xin was startled by the old professor''s humble attitude and hastily expressed that he didn''t mind.


    If the old professor confronts himself or ignores himself, Chen Xin feels that he can accept it and doesn''t care too much. However, an old man apologizes to himself in front of a group of people with such a sincere attitude. Whether he is a professor or not, or whether he really needs to apologize, Chen Xin feels that he should be more generous.


    The old professor obviously apologized very sincerely. After apologizing, he took a look at the crowd around him and realized that he might have caused trouble to Chen Xin. So he didn''t stay any longer. He just said to Chen Xin, "it seems that today is not a suitable time. Let''s stop here. I''ll visit again when the next time is right ¡£¡±


    With that, the old professor turned to leave. He saw that his students were still indignant and didn''t scold him. He just said to him, "follow me first."


    Then he left with his students.


    When others saw the result, they could not help whispering, but they didn''t say much and soon dispersed.


    But Chen Xin stayed in the same place and could not help rubbing his chin, thinking about what was going on.


    If all this is on the surface, there is no problem. Perhaps the old professor is just a temporary prejudice. Now that he can sincerely apologize, Chen Xin will forgive him and his students.


    But if it''s all designed Chen Xin can only say that the darkness of human heart is beyond our imagination.


    However, he didn''t think that the old professor was intentional. After all, from a certain point of view, the old professor could have apologized more sincerely just now, and even pulled his students to play a bitter game, which could have forced Chen Xin into a corner, from the original reason to no reason.But the old professor didn''t do that. After apologizing, he turned around and left cleanly, and didn''t make a pretence on purpose, which made it difficult for Chen Xin to judge whether the old professor was a good man or a bad man.


    Shaking his head, Chen Xin went back to his room.


    Although it bothers Chen Xin a little, it''s just an episode. After thinking about it, he ignores it. For him now, he really has no time and energy to worry about it.


    Compared with worrying about such intrigues, Chen Xin feels that it is more practical to spend some time thinking about isotope generators.


    It''s the end of the world now. It''s too shallow to think about personal interests and intrigue.


    To care with such people will only lower one''s own level to the other''s, and then be defeated by the other with rich experience.


    And even if we win, we will not get any benefits, let alone any improvement and help to the living conditions of Yanguo and the whole mankind.


    You know, even if Chen Xin can transform the boilers and heating equipment of all the refuges in the city, all he can save is this city. For Yanguo, where almost the whole country is shrouded in the snowstorm, it''s just a drop in the bucket. After all, 99.9% of the people in Yanguo are suffering from the snowstorm.

 Chapter 300

    Under the organization and planning of the municipal government, Chen Xin spent about a week to complete the transformation of three large shelters and six medium-sized shelters in the urban area, so that the urban area was still warm under the storm.


    Chen Xin didn''t have a very intuitive feeling about the significance of this warmth before, but when he finished the boiler transformation of the hospital and went to the pedestrian street shelter to carry out the boiler transformation of this large shelter, the survival status of the survivors in the shelter still shocked Chen Xin.


    Pedestrian street shelter is a large underground space, and because its structure is a double-layer underground pedestrian street, there is a sunken square. Although it was designed as a civil air defense facility at the time of construction, its ventilation is very good.


    Good ventilation is of course necessary for underground buildings, but good ventilation also means that heat loss is easier, especially when the underground space is larger, more vents are needed and more heat is lost.


    As a result, the temperature of pedestrian street is lower than that of other medium-sized shelters.


    In particular, the sunken square in the middle of the whole pedestrian street is open. Even if reinforcement and heat preservation measures are taken during the reconstruction of the refuge, it is still an important problem that will reduce the temperature of the refuge.


    Moreover, the strip structure of the pedestrian street also leads to the rapid flow of air in the whole refuge, which may not be felt when walking normally. However, when the temperature drops below zero, the flowing air will make any point of heat in the refuge quickly dissipate and lose.


    As a result, there are many people suffering from frostbite and hypothermia in pedestrian street shelters. Many people are even unable to leave the room to treat themselves. They can only lie in the cold and narrow room, wrapped in cold quilts and blankets, huddled in front of the radiator, and rely on the little bit of residual temperature to get worse in shivering.


    Although the managers of the shelters have arranged inspectors to help the survivors in need, there are too many people in large shelters and the places are too large. Even if there are inspectors, it is difficult to provide help and treatment for everyone in time.


    Many people are seriously ill before they can be sent to the hospital for treatment, and this is good, some people because of physical weakness or other diseases, even directly in the cold.


    When Chen Xin arrived at the shelter on the pedestrian street, at the entrance of the sunken square, he saw no less than 20 body collecting bags, which had been filled with bodies. In this way, they were arranged in a row at the entrance of the shelter, waiting to be cremated.


    This is a very heavy picture. Looking at the survivors who huddle in the small rooms transformed from the facade of the original underground pedestrian street, Chen Xin can deeply feel their helplessness and despair.


    Doomsday, disaster, cold All of this is hopeless.


    It has to be said that the pedestrian refuge is indeed the worst one in the city. Compared with the other two large shelters, it is not so easy to lose heat.


    In fact, even after Chen Xin completed the renovation of the boiler and even replaced the heating pipeline of the refuge with air heating, the temperature inside the refuge did not rise above zero.


    But fortunately, the temperature here has been significantly improved after the boiler transformation, from minus 20 degrees to a few degrees below zero, barely making the residents inside the shelter no longer feel warm with quilts on the radiator.


    After Chen Xin renovated the boiler and heating pipeline, the residents in the shelter can still make the temperature in a small space rise above zero under the effect of heating as long as they close the doors of their rooms.


    But compared with other shelters where the overall temperature has been raised above zero, the conditions are undoubtedly much more difficult.


    Fortunately, the hot water from the boiler room is still very hot, so people here can have a good hot bath to relieve the pain caused by the continuous low temperature and cold for many days.


    After the reconstruction of three large-scale shelters and six medium-sized shelters in the urban area, Chen Xin can finally put his energy on the isotope generator.


    After all, Chen Xin said that although he has completed the boiler renovation of all the large and medium-sized shelters in the urban area, so that more than 100000 people will not die of cold in the blizzard, for the whole country, more than 99.99% of the population is still suffering the same fate.


    And they are not so lucky, they can have people like Chen Xin to help them, they can only rely on their own to fight the storm.


    Chen Xin is not confident that they can survive this.


    For this reason, Chen Xin also specially consulted people from scientific research institutions and asked them if there were other ways to help those who were still suffering in the snowstorm, but the answer was frustrating.


    Even the country has no good way to deal with this terrible snow disaster, only to increase heating to survive.


    So this makes Chen Xin pay more attention to the isotope generator.In theory, an isotope generator is enough to supply all the power needs of a shelter, and the equipment itself occupies a small area, which can be put into a normal size bedroom after assembly.


    If it can be mass produced and then transported to the shelters all over the country, it can provide them with abundant electricity for electric heating, so as to cooperate with coal-fired heating, so that they can support themselves in the snow disaster that they don''t know when it will end.


    This is why Chen Xin knows that the finalization and manufacture of isotope generator will take time, but he still devotes his energy to this project.


    If it was in the past, with the adjustment of weather system, no matter how severe a snowstorm was, it would last for a few days, and the large-scale cold wave cooling weather would not last long.


    But now that the weather system has collapsed and the world is frozen, the Blizzard has lasted for more than two weeks, and no one knows when it will end.


    It could be tomorrow, it could be next week, it could be next month, it could even be like a storm on Mars for a whole year.


    Therefore, in order to avoid further deterioration of the situation, Chen Xin thinks that if he can do it, he should try his best to do it, at least to save more people instead of watching them freeze to death.

 Chapter 301

    The research of isotope generator still starts from isotope thermoelectric battery.


    As the energy source of isotope generator, isotope thermoelectric battery is a mature thing for Chen Xin. He only needs raw materials to make it continuously.


    Of course, as a person, the efficiency of manufacturing isotope thermoelectric batteries is limited. Even if he has the upgrade function of the system, he can upgrade as long as he sees it. However, in terms of efficiency and cost performance, it is more appropriate to make the production line for other people to produce.


    However, before that, in order to facilitate the manufacture and research of isotope generators, Chen Xin used a number of isotope thermoelectric cells as research materials.


    "Mr. Chen Xin, how to make this isotope generator?" The researchers sent all the materials and parts Chen Xin needed to his lab, and looked at him eagerly, wondering how he would make this kind of isotope generator that sounds like science fiction.


    To this, Chen Xin just laughed, and then explained: "I''m not easy to explain, just look at it. Generally speaking, connect the three batteries together, and then increase their output power."


    With that, Chen Xin began to assemble the parts in front of him.


    As before, although the system can be upgraded infinitely, turning ordinary car batteries into isotopic thermoelectric batteries, Chen Xin still has no way to upgrade them into isotopic thermoelectric batteries if he does not assemble three isotopic thermoelectric batteries together and make something that can be called a bracket and combine them into a whole that can be regarded as a generator The generator''s.


    After all, three batteries are three batteries. It is impossible to regard them as a generator without putting them together.


    Seeing that Chen Xin was assembling parts, these researchers came together in a hurry to help him. Although they were busy, they were also orderly. They didn''t bring any obstacles to Chen Xin, showing high professional quality and organization.


    When Chen Xin and others assembled the parts, the old professor who had a conflict with Chen Xin also rushed over.


    Although the project should be highly confidential and should prevent others from waiting, the old professor succeeded in letting the person in charge of blocking at the door come in and intercede with Chen Xin after showing his identity.


    "The old professor? He wants to take part in the project, too? " Chen Xin was a little surprised, but also doubted the purpose of the old professor.


    But the person who came to talk to Chen Xin explained to him, "this old professor, whose surname is Zhou, is the academic leader of the Institute of science and technology, and is also the leading nuclear physics expert in China. If anyone in the Institute of science and technology can help Chen Xin in the development of isotope generators, it''s this old professor."


    Chen Xin didn''t comment on this comment, because he really didn''t understand these things. In recent years, too many experts and scholars from all walks of life have emerged on the Internet, and individuals dare to say that they are well-known scholars and authorities in the field. The proliferation of such words once made the so-called experts become experts.


    However, considering that all the people around him are researchers sent by the state, Chen Xin nodded after hesitation and agreed to let someone invite the old professor in.


    The old professor was soon invited in and saw what Chen Xin was assembling. He didn''t comment rashly or intervene. He just stood aside and watched Chen Xin assembling things very carefully.


    The assembled device is a triangular bracket about two meters high, with a disc on the base and upper end, and three slots on it just for fixing the isotope thermoelectric battery.


    In addition, there are some simple circuits at the bottom of the whole bracket, which seems to be used to export the battery power. The whole device looks rough and crude.


    No one in the lab, however, found this strange.


    Chen Xin knows that after upgrading, this thing will look good. There is no need to spend so much unnecessary energy on the prototype.


    Old professors and other researchers have long been used to the rudimentary appearance of equipment prototypes. After all, in scientific research, we have always pieced together to solve the problem and then slowly improve it.


    No prototype has ever been fully functional, and no researcher will consider whether it looks good when making a prototype.


    But even so, the old professor frowned and said, "your circuit design is too rough. You just connect three batteries in parallel. Why don''t you optimize the connection mode of the circuit?"


    "Assemble the equipment first, and I''ll solve the optimization later." Chen Xin looked back at the old professor and explained to him, "this is my ability. I got acquired acquired scholar syndrome by accident before. I can optimize and transform any equipment, but I only know how to do it, and I don''t know how to explain the principle."


    "And that kind of thing?" The old professor obviously felt that his cognition had been impacted, but he didn''t say much. After all, Chen Xin''s achievements in reforming the boiler were solid, and he didn''t intend to make any comments before he saw Chen Xin''s ability.As long as we can verify the results and copy the process, in the old professor''s view, this is scientific. Science should not be a dogmatic theorem formula, but a cognitive method that can be falsified. As long as we can falsify, it is in line with the laws of science.


    As for the incomprehensibility, it can only be said that the accumulation of knowledge is not enough, and it is impossible to recognize all things.


    Chen Xin didn''t plan to explain to the old professor that sometimes it is more effective to do it once than to say 10000 times, so after he installed three isotope thermoelectric batteries on the device in front of him, he directly started the upgrade function of the system.


    The green light flashed, and in a flash, the original rough equipment had changed dramatically. The original bare equipment body was wrapped with a beautiful white shell, which looked simple and clean.


    The circuit connection rejected by the old professor also has a new appearance. Although it is covered under the shell, it can be judged that the circuit has been completely optimized.


    The old professor who saw Chen Xin use his ability for the first time was already in shock. He was shocked by what he had "seen" and could not help muttering to himself: "how It''s like... "


    The old professor, who has been studying hard all his life, doesn''t know what to say now. He can''t even find an accurate adjective to describe what he "sees".


    Chen Xin can''t help feeling helpless when he looks at the old professor. Fortunately, his ability doesn''t come from the myth of kesulu. Otherwise, the old professor will be impacted and become a believer of the old dominator in the face of the performance of the system?


    After all, in the eyes of ordinary people, system upgrade is really indescribable enough.

 Chapter 302

    Although the process of Chen Xin''s upgrading is an indescribable embodiment for ordinary people, the more knowledge they have, the more information they can get, and the fool will not get any information, ordinary people can''t realize the truth of the system upgrading in any case.


    However, we can''t realize the truth of the system upgrade. For people with rich knowledge, such as old professors and other researchers, it''s quite fruitful to see Chen Xin upgrade his equipment with his own eyes.


    "Can we still do this? The circuit can be connected in this way, and isotopes can catalyze the decay process in this way, releasing more radiation energy? " In the process of Chen Xin''s upgrading, the old professor saw a process of completely subverting the existing physical theory, which almost made him feel the destruction of the three outlooks. The whole person''s understanding of physics established in decades was almost subverted.


    Because from the physical point of view, the decay period of isotopes, that is, the half-life, is the inherent characteristic of radioactive elements and will not be affected by other factors.


    This is also the reason why scientists can estimate the age of blue stars and even the whole universe by the decay of radioactive elements, because this cycle is stable and free from any interference.


    If the decay of radioactive elements can be accelerated by some means, the nuclear waste will not only be buried and placed in no man''s land, waiting for its natural decay.


    If this is true That''s really a big event enough to change the world, because it will overturn the theoretical basis of modern physics and make the whole knowledge system of physics re established.


    "How do you accelerate the decay of isotopes?" The old professor excitedly grabbed Chen Xin''s clothes and forced him to ask. His excited look was just like an old man who had been holding on for decades seeing a peerless beauty.


    Although this description is not quite appropriate, for a scientist who has been studying nuclear physics all his life, Chen Xin''s technology that can accelerate the decay process is undoubtedly a peerless beauty, which has irresistible charm for any scientist who understands its significance.


    "Old man, can you let me go first? I can''t explain why you hold me like this Chen Xin tried to break off the old professor and grasp his hand, but he didn''t expect that the thin old professor''s hands were as hard as pliers and hard to break.


    When Chen Xin said that to the old professor, he let Chen Xin go and asked him, "how did you do it? Why can the decay process be accelerated? Did you know that it completely overturned the foundation of modern physics? "


    "Please calm down, old man. I have just said that I know how to do it, but I don''t know how to explain it." Old professor Chen Xinchong grinned bitterly.


    This is simply the best example of ten lies to make up for one lie. Now he really can''t explain to the old professor how this is going on, and how the system can completely subvert the cognition of modern physics.


    However, a researcher on one side seemed to have gained something, thought about it for a while, and said, "will it be through weak nuclear force to affect decay? This is feasible in the existing physical theory, but human beings have no way to affect the weak nuclear force


    "Human beings are only in the cognitive stage of the weak nuclear force now, and even the theoretical system has not been completely established, let alone the influence and utilization. If it is the weak nuclear force, it would be terrible, right?" Another researcher can''t help but feel a thrill. The device that can affect the secondary force is so lightly made in front of him. It''s really like the shock of an atomic bomb exploding directly in front of his eyes.


    The researchers argued about it endlessly, but the old professor himself let Chen Xin go and threw himself on the equipment. After observing it carefully for a while, he directly asked Chen Xin, "can you take it apart? I''ll take it apart and study it carefully! "


    "Of course. I made the prototype for you scientists to do reverse research." Chen Xin readily agrees that as long as the old professor doesn''t force him to explain the principle, it''s no problem for him to do two more for research.


    Just when the old professor asked two researchers on one side to help dismantle the isotope battery on the machine and begin to dismantle the isotope generator, other researchers on the other side were still arguing about how to realize the decay catalysis of radioactive elements.


    "Nuclear decay is a spontaneous change of the nucleus. It is a quantum transition process. It should obey the laws of quantum statistics. The exact time of decay is unpredictable, but the period of decay is constant. I think the principle of this machine is to complete the decay process in a short time, and the period of decay itself is constant." According to his own knowledge system, one of the researchers put forward his own understanding.


    "But how can decay be concentrated in a short time? Isn''t this still going back to the application of weak nuclear forces? " Another researcher thinks that this is nonsense and unscientific. The decay process should be uniform and constant without any influence. Otherwise, the half-life of matter will not be an important means of measuring time.


    When a group of scientific researchers argue, Chen Xin can only stand aside and watch them discuss. He is not a Xueba. He only learned the basic concepts of nuclear physics in high school, and he is not even a scratch. Now watching a group of scientific researchers almost fight for this argument, he can''t get in the middle of it. At the same time, he laments the wonder of the world.Who would have thought that although he was not a scum, he was not a bully. What he made could make a group of bullys almost fight?


    "It''s the weak nuclear force that affects the decay, but do you influence the decay through the unity of electromagnetic force and weak nuclear force and the weak interaction of electricity?" The old professor took apart the equipment, looked at the internal structure of the equipment, frowned and thought, but suddenly asked a question.


    Chen Xin has no way to answer this. As for the weak nuclear force, he checked the data when he was writing novels before and knew that it was called the four basic forces together with the strong nuclear force, electromagnetic force and gravity.


    In the popular science soft articles on the Internet before the disaster, the four basic forces were predicted by Einstein to be "divine power" that "once human beings master these four basic forces, they can enter a higher dimensional universe and change the world". Some even claimed that once they master these four basic forces, time is just a coordinate, and human beings can roam in time.


    Now, the equipment based on the application of electromagnetic force and weak nuclear force is placed in front of these researchers.

 Chapter 303

    The impact of isotope generators on scientific researchers is obviously beyond Chen Xin''s expectation, and he did not expect this kind of thing to be so exaggerated.


    For Chen Xin, it''s just a new type of generator, but it''s obvious that sometimes a thing''s importance doesn''t depend on whether it''s complex or expensive. It may be a very simple thing, but it contains a high content of science and technology.


    This is just like the smart phones that can be seen everywhere in our daily life. If we put them into the World War II, they will be enough to change the world.


    Because at that time, people could not imagine that computers could fit into a person''s pocket.


    Therefore, Chen Xin can understand the impact and impact of the isotope generator, but it has not affected his original plan and arrangement.


    At a time when a group of scientific researchers are devoting their energies to the dismantling of the isotope generator, hoping to crack the technology and find out how to use the electromagnetic force to influence the weak nuclear force, thus changing the physical law of the decay cycle, Chen Xinze and a few less crazy scientific researchers are preparing for the establishment of the isotope thermoelectric battery production line.


    "According to the current statistics, large shelters do need isotope generators, medium shelters can also install isotope generators if they have high energy consumption projects, while small shelters can use isotope thermoelectric batteries directly to meet their power needs." A scientific researcher is explaining to Chen Xin with a form.


    This kind of statistics is very necessary. Although Chen Xin has helped build the production line, there is no need to worry about the output, it can not be said that every refuge is equipped with isotope generators, which will constitute a serious waste.


    In this doomsday, the acquisition of every resource is more difficult and precious than before the disaster, and there should not be any waste.


    Moreover, with the actual data investigation, we can also control the output of isotope thermoelectric batteries and isotope generators, so as to avoid that too many generators are built without enough batteries.


    After all, a generator needs three batteries. If the output of batteries can''t keep up, even a generator is useless.


    "Let''s set up a battery production line first. We can produce a batch of isotope thermoelectric batteries, and let some shelters ease the situation first." After listening to the statistics, Chen Xin nodded clearly.


    The researcher with the investigation report also nodded and affirmed: "this is the most suitable solution at present. Countries of isotope thermoelectric battery have had relevant reverse analysis before. If we set up a production line here, with reference to our technical experience, other places can also set up new production lines quickly, which can effectively improve the production efficiency Quantity.


    I don''t really recommend that we rush to build the production line of isotope generator. Its technology has not been analyzed yet. Even if we build the production line, it is difficult to effectively control the product quality. If the yield is too low, it will only be a waste of resources. "


    "There''s no need to worry about the yield. Workers only need to know how to operate the production line. They don''t need to know the technical principle of the product." Chen Xin retorted, but did not oppose the decision: "but what you said is reasonable. Let''s set up the production line first."


    "OK, then we''ll contact the city government to determine the venue first." The researcher nodded. Although it''s a good thing that the matter has been settled, the next work is not easy.


    Now there is still a snowstorm outside, and the outside temperature is more than - 70 degrees below zero. In such an environment, let alone construction, even the transportation of materials is extremely difficult.


    Even a train full of coal is in danger of derailment under the strong wind of level 12. Although the country has made every effort to ensure the transportation of railway materials, and the comrades on the railway front are risking their lives to maintain the smooth railway transportation, the supply of materials is still tight.


    In the case of limited transportation capacity, the most important coal has always been the priority of transportation. If there is a need to transfer materials from outside to build a production line here, it will certainly occupy valuable transportation capacity, which is likely to cause more serious impact.


    Therefore, how to allocate materials requires careful study by the staff.


    As for the construction and site, it''s not too much trouble.


    After the scientific researchers went to coordinate with the city government, a small shelter that had been sealed up before was allocated. Although the place is not big, and the interior also needs to be renovated, there is at least one place.


    And the construction workers To put it mildly, the most important thing now is people.


    Although the production line of this level certainly needs professional construction personnel, it''s good to have someone to work in the current world. It''s hard to find too professional personnel for a while.


    In a word, with the cooperation of the municipal government, the production line of isotope thermoelectric battery is still under construction.


    While the municipal government and scientific research institutions are promoting the construction of the production line, Chen Xin and Qin LAN go back to their refuge together.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª"It''s still comfortable here!" Qin LAN takes off his power armor and stretches his body. At the same time, he asks Chen Xin, who is also taking off his power armor: "why do you want to come back suddenly? Is there anything you have to come back for? "


    "Well, there are some things to do. I can use the workbench at home easily." Chen Xin also moved his body joints. Although the power armor has a power assist device, wearing it for a long time will also make people tired.


    In fact, Chen Xin wants to make a set of universal tools, so that he can easily set up the production line of isotope thermoelectric battery.


    Of course, this universal tool is not the handheld device in "quality effect" that integrates microcomputers, analysis and detection kits, and small processing and manufacturing tools. What Chen Xin wants to do is just a similar manipulator.


    In short, it is to integrate a microcomputer, some analysis and detection instruments, and a set of processing tools into a mechanical arm that can be installed on the body.


    This is also Chen Xin''s idea after he encountered some inconveniences when he was working in the urban area recently. If a person always takes time to find tools or frequently replace the driver and spanner when he is working, everyone will want a tool that can cope with all work situations.


    What''s more important is that Chen Xin''s universal tool should also have the processing ability of worktable in his vision, and can make articles according to drawings.


    This is very important for Chen Xin, because next he plans to build an isotope thermoelectric battery production line with the help of a mechanical arm.

 Chapter 304

    In front of the workbench, Chen Xin is designing his own universal tools.


    Although the inspiration of this thing comes from the universal tools in the "quality effect" game, Chen Xin still can''t do the thing that can realize all functions with only one chip implanted in the game, or he doesn''t have enough survival and materials to upgrade it.


    So Chen Xin plans to build a mechanical arm that integrates all the commonly used tools, which is equivalent to carrying a toolbox with him.


    Moreover, after the installation of a microcomputer and a scanning analysis instrument, the manipulator can also analyze the situation by itself and replace the appropriate tools, eliminating the trouble of users changing different types of spanners and screwdrivers.


    People who don''t work in factories may never understand how annoying it is to have no proper spanner or driver when working on site.


    Sometimes, because a spanner can''t be found, the work will be delayed for hours or even days to borrow and buy, which often causes a lot of time delay. For factories, the loss caused by one day''s equipment shutdown is hundreds of thousands or even millions.


    So if you can have such a manipulator, it''s really a great choice, even if it will be very heavy.


    Chen Xin conceived this mechanical arm in his mind, and at the same time, he was putting together what he needed.


    There is no ready-made microcomputer, but Chen Xin found an old mobile phone as a substitute. Now the mobile phone is useless, so it''s just right to replace it.


    As for the analysis and detection instruments, Chen Xin got cameras, temperature guns, rangefinders, velocimeters, tachometers Although there are a lot of things to pile up, after they are integrated, there will be no problem.


    As for the tool aspect, it is the simplest. Taking a toolbox out can meet all kinds of needs.


    But in addition to these, Chen Xin also wants to add a 3D printer to it.


    This comes from Chen Xin''s father''s suggestion. People who have been involved in site construction all the year round know that sometimes parts need to be processed on site, such as welding a bracket, connecting an elbow, or even temporarily processing a part


    Because on-site construction often meets all kinds of situations. It''s very common that the equipment can''t be installed and the parts don''t match. In his decades of working career, Chen Xin''s father can''t remember how many parts he has temporarily processed on site.


    So seeing that Chen Xin wants to integrate a universal tool, as a father, he still gives his son some experience from the elderly.


    Chen Xin naturally follows his father''s advice, cutting, welding, sheet metal, boring and milling All these functions are necessary, but Chen Xin prefers to print a suitable part directly with 3D printing rather than using materials to process parts on site.


    It''s just that he doesn''t have a 3D printer on hand yet, so this function can only be put on hold for a while. After he has finished the mechanical arm, he will see if there is any alternative plan when he upgrades it for the second time.


    Moreover, not only 3D printing has not been installed, but also argon arc welding, electric welding, sheet metal, boring and milling functions have not been integrated due to the lack of equipment, so they can only wait for the second upgrade.


    However, this is not a big problem for Chen Xin. It''s just a matter of spending more time to survive in the second upgrade.


    What''s more, even with these shortcomings, he also wants to make this manipulator.


    Chen Xin found an angle steel, cut it on the worktable, and began to pile up various tools and instruments.


    It seems that there is a feeling that the big green skiers are thinking about a new big bang. The sparks caused by metal cutting are completely out of order. They are just tools stacked together. Some instruments are even wrapped up with tape


    The finished product not only has a strong punk style of waste soil, but also has a very green maneuverability. It''s rough, bulky and not even practical. I think it''s so good, so I did it without any reason or design specification.


    Of course, what Chen Xin eventually used was not such a green thing. In fact, he couldn''t use the thing he finally assembled because there were so many tools installed on it that he even had to work hard to pick it up, let alone use it.


    So an upgrade is still needed.


    After a flash of green light, the original green leather type equipment has become a mechanical arm with the style of mechanical theology. Although it is thick and complex, it has become a lot of neat. There is no more excess thread and tape. The originally exposed angle steel has also become a silver white support shaft, wrapped in a metal shell, and has become a real mechanical arm.


    The complicated tools and instruments on the mechanical arm are well integrated into the mechanical arm, and some replaceable parts and components are neatly stored, and can be easily replaced at any time.


    The whole mechanical arm looks like a big backpack. After the back, there will be a three-axis rotating mechanical arm folded behind, and next to it is a display screen that can reach to the side of the head to operate and display data.Of course, the 3D printing, welding, sheet metal, cutting, boring and milling processes that Chen Xin needed before are also integrated into the mechanical arm. Now the mechanical arm is capable of all the needs of on-site construction. Even Chen Xin has added a detachable drill bit on it, which can even be used to mix cement with a blender.


    However, although the function is perfect, and the robot arm becomes lighter and more convenient to use after integration and upgrading, Chen Xin found that it still can''t be used easily by one person after trying.


    At least Chen Xin himself can''t easily pick it up without wearing power armor or exoskeleton.


    This makes Chen Xin scratch his head a little. He can''t pick up the tools when he makes them. It''s really ironic. Does he have to get fit and become a weightlifter again?


    Or do you want to integrate directly into the power armor and make yourself a guest casting master of mechanical God?


    Chen Xin scratched his eyebrows and thought this idea was quite good.


    And there is a saying that he really feels like a foundry master now.


    Chen Xin drives his power armor and asks Qin LAN to wear her power armor to help install the whole mechanical arm on the back of his power armor.


    And then Just need to upgrade again, a set of power armor with mechanical arm will appear.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 305

    After the finished universal manipulator is installed on the power armor, it''s like the back of the power armor has a third hand.


    Although the "hand" is a three-axis mechanical arm with a drill, pliers and a screwdriver at the front end, and the hidden saw blade makes it look more like a tool of torture than a tool, in terms of the way it is used, both of them can be used at the same time.


    After all, as a tool, it is used to process steel. If you use it to process the body, it will only be bloody.


    In particular, the robot arm now has its own 3D printing function. As long as the brain hole is big enough to play, it can make the evil spirits happy and play magic.


    However, Chen Xin didn''t make this mechanical arm for 18G. It''s a serious mechanical tool for him. At most, he sometimes plays as a close combat weapon of power armor.


    Putting on the power armor again, Chen Xin tests the performance of this mechanical arm in front of the workbench. The way to test is to use this mechanical arm to make and add accessories to Qin Lan''s power armor.


    "Is this a sight?" Qin LAN looks at Chen Xin putting several lenses and lenses on her power armored helmet and asks him curiously.


    "The combined multi vision mode collimator has infrared, low light level, sonar and other modes. It can lock life signals within 500 meters through sound waves, heat sources and other modes. Even if the target is hidden in a building or buried under the ruins, it can easily find and lock the other side." Chen Xin explained to Qin LAN, and also tested the function of this set of sight through the mechanical arm: "at the same time, it also comes with the hacker function. Within 100 meters, you can blackout all the devices that can be connected to the wireless network signal through the built-in signal transmitter. Inside, I added a small program to you. The function of blackout device is automatic, of course, you can also Take wired connection, manual black in, test your hacker technology. "


    Chen Xin said that he also pulled out a connecting line from the hidden part of the sight, showing Qin LAN the wired connection mode of the device.


    "What if the connector doesn''t match?" Qin LAN some Lengshen looking at Chen Xin, did not expect that he could put a sight to make so many flowers, but what she thought at this time is not how many tactics she can do with this set of sight, but how to do if the connecting line can not be inserted.


    "The interface of the thread head has a deformable adaptive structure. In theory, all interfaces can be plugged in. If there is no interface, it''s wireless black in." Chen Xin activated the deformation function of the interface and showed Qin LAN the interface like liquid metal.


    At this time, Qin Lan also returned to normal calm and thinking, and asked Chen Xin, "how much is the multiple of this sight?"


    "1.5 ~ 16 times magnification, millisecond level auto zoom, with wind resistance, wind deviation correction calculation, I think in your sniper, enough to play a strong power." Chen Xin put the thread back, adjusted the lens of the collimator to zoom, and tested their sensitivity.


    Hearing this, Qin LAN can''t help feeling surprised. It''s a magic weapon for a sniper.


    "And the gun?" As a sniper, with an artifact like sight, a high-precision sniper rifle is enough to incarnate the battlefield God of death.


    "I can make it, but now..." Chen Xin took a look at the power armor, shook his head and said: "first, there is no weapon manufacturing license, second, there is no actual need, because it is meaningless to build a sniper gun that is also used for mecha. The caliber is lower than 12.7mm, but that kind of large caliber sniper rifle Do you think I need enemies with weapons of this level? "


    Qin LAN heard Chen Xin say that and thought about it seriously. It seems that it is true. After all, for the power armor, the size of the gun needs to be made separately, and because of the bearing capacity of the power armor, it is enough to bear much more recoil than the human body.


    In that case, why use small powerful guns? Make a big bang! The best is a big bang that can solve all the problems. As long as you fire one shot, you can kill all the enemies!


    Of course, such a green weapon manufacturing idea is a bit extreme, and it''s not suitable for Qin Lan''s power armor which is going to develop to the sniper route.


    After all, even if Chen Xinzhen made a single soldier mushroom egg launcher, he could directly grow mushrooms to play with relying on the radiation protection ability of the power armor, which did not need a sniper power armor to do this.


    The weapon that is really suitable for Qin LAN should be a top-level sniper rifle with high precision, high power and high penetration. It''s better to have no wind deviation within the effective range, ignore the wind resistance, and the bullet can penetrate the tank armor. Such a gun is suitable for sniper type power armor.


    As for Chen Xin''s own power armor, he is a master foundry after he has the universal mechanical arm. He is not going to the battlefield at all, so it is enough to have enough self-defense ability. Even if there is any place to fight, he can use the 3D printing function of the mechanical arm to build a Vulcan gun on site to sweep all directions, so he does not need to be equipped with special weapons .


    With these words, Chen Xin also completed the transformation of Qin Lan''s power armor.


    There are not many places for Chen''s new transformation this time. In addition to adjusting the weight, protection and output mode of the power armor itself to make it lighter and more dexterous, it only improves its agility and concealment performance, making it more suitable for snipers and the sight added to the helmet.The reconstructed power armor is much thinner, and there are five sight glasses stacked on the right eye of the helmet, but there is not much change.


    But for Qin LAN, he suddenly fell in love with this set of power armor. After Chen Xin said that the transformation was completed, he couldn''t wait to put it on and wanted to try its performance.


    Chen Xin didn''t stop this. After all, after the transformation of power armor, it really needs to test its performance.


    Moreover, his own set is not only equipped with a universal mechanical arm, but also made some other detailed modifications, which can also test the performance together, so that he can familiarize himself with the ability of this set of power armor for better use.


    But in addition, another important thing is to calculate the design drawings of general purpose power armor based on these two sets of power armor.


    In today''s snowstorm weather, a set of power armor can do a lot of things. Chen Xin needs to hand over the drawings of power armor and exoskeleton protective clothing to the state, so that they can make more exoskeleton protective clothing and power armor, so that they can better save themselves in such Snowstorm Weather.

 Chapter 306

    After upgrading the power armor, Chen Xin and Qin LAN rush back to the city.


    Originally, Han Ping and Han Ze wanted to follow Chen Xin together. Han Ping was Chen Xin''s bodyguard, so there was no reason not to follow Chen Xin. Han Ze was called by Han Ping to fight for Chen Xin.


    However, Chen Xin refused the two brothers'' proposal and left them in his own shelter for good reasons.


    "My parents and my two friends live here. They need protection. Han Ping, since you are my bodyguard, please protect my family. If I have this power armor, no one can hurt me." Chen Xin says to Han Ping, who wants to go downtown with him.


    Faced with Chen Xin''s strong reasons, Han Ping can only stay in the shelter, responsible for protecting Chen Xin''s parents and Mo Qingyan''s sisters.


    Chen Xin and Qin LAN went through the snowstorm again and returned to the urban area.


    This time, however, instead of going to the city police station or polytechnic, they went to a small refuge designated by the city government as an isotope thermoelectric battery production line.


    Obviously, the city government has sent someone to clean up the place. Even if the heating boiler has been turned on in this small shelter in the low temperature environment of more than minus 70 degrees, it is shivering and even freezing.


    However, with the mobilization of the city government and the slight improvement in the situation of various shelters, there are still enough people to clean up the area and begin to tear down some partition walls according to Chen Xin''s previous requirements.


    Some of them are ordinary light partition walls, which can be easily removed by removing the fixed buckle, but some of them are brick walls which play a supporting role, so it is difficult to remove this part.


    Even under normal circumstances, it takes a lot of effort to demolish a brick wall. Now, with the low temperature of tens of degrees below zero, even the soil can freeze harder than granite, and a hammer will only leave a white mark. In this case, it is not a big hammer that can demolish a brick wall made of water mud and bricks.


    After arriving here wearing power armor, Chen Xin also tried to use power armor to demolish a brick wall. As a result, he could hit the brick wall with power armor with a punch of more than 1.25 tons, which was just a hole.


    And this also makes the mechanical structure of the power armor hand slightly deformed. Obviously, this kind of maximum force hitting hard objects will damage the mechanical structure of the power armor.


    However, this is obviously not the correct use of power armor. Although this can be done, just like anyone with a brain will choose to smash the wall with a hammer instead of hand, power armor can smash the wall with a fist, but it is unnecessary.


    After activating the mechanical arm on his back, Chen Xin manipulated the steel hand to switch to the right tool, and then along the place where he had just smashed his fist, he easily expanded the big hole in his fist, and the bigger it was, the bigger it was, and soon he pulled out a big hole one person high.


    This kind of efficiency is undoubtedly amazing, but it is the power armor should play.


    Qin LAN asked the workers to borrow a hammer, and then he swung it directly to the wall. After several rounds, he also succeeded in smashing another wall into a depression, kicking it up and kicking a big hole.


    In fact, even if half of the brick walls were demolished by Chen Xin and Qin LAN, the workers took a lot of effort to demolish them. It usually took them a long time to demolish so many bricks. The progress was quite slow.


    But even so, Chen Xin and Qin LAN did not use power armor to help demolish the wall, but found the person in charge of the construction and confirmed the structure of the refuge with each other.


    Although it has been confirmed as the production line of isotope thermoelectric battery, the specific construction drawings of the production line have not yet come out, because the drawings themselves need to be modified according to the structure of the site. Although the plant is normally built according to the equipment requirements, there are also equipment that need to be installed according to the site.


    So this is not a strange thing. Moreover, although the site and other things have been almost prepared, in fact, because there is no precedent to refer to, the production line is just the idea in Chen Xin''s mind, and it has not been turned into a finished product at all.


    Of course, this is not a problem at all for Chen Xin. Having an idea is enough to use the upgrade function of the system to upgrade the production line.


    According to Chen Xin''s idea, the whole production line should include raw material processing, metal parts casting, radioactive loading processing, high-precision parts production and other aspects, and finally converge to the final assembly line.


    It is difficult to arrange the metal parts casting and radioactive charging processing.


    Metal parts casting is mainly used for radiation isolation inside the battery to ensure that the radiation released by radioisotope inside the battery will not leak, so this part will use lead alloy as material for high-precision integral casting.


    The most critical problem of casting parts is the need for a high temperature furnace to melt the material into a state of fusible casting.Of course, the use of stamping manufacturing is not bad, but now in this environment, water press is obviously not suitable, on the contrary, the furnace is more suitable for some.


    Fortunately, since the isotope generator has been built, it is enough to meet the power demand of the electric furnace, so there is no need to worry about the energy problem.


    The energy consumption of the electric furnace is easy to solve, but the heat released by this device during work is not so easy to solve. After all, it is in the closed underground. All kinds of problems brought by using the furnace need to be considered.


    The oxygen consumed, the high temperature released, and the precise temperature control environment required during the furnace operation are not things that can be easily determined. If Chen Xin does not have a system, he wants to arrange these things, but he needs detailed demonstration and calculation. After the final results are obtained, he can prepare for the installation of the furnace.


    As for the radioactive loading and processing, it is better than the furnace arrangement. As long as the anti radiation measures are taken, and even the country can process and send the radioisotopes as raw materials in other places, we only need to be responsible for the loading here.


    Although radiation protection is not easy to do, considering that every link of the production line can be exposed to radiation except the initial processing of raw materials, the whole small shelter is the place where the whole process of radiation protection needs to be done. In fact, this can only be regarded as a rigid requirement, on the contrary, there is no need for additional calculation and arrangement.

 Chapter 307

    Although the layout of the production line is very troublesome and requires a lot of professional knowledge, the good thing is that there are professional people to do professional things. Chen Xin only needs to submit the drawings of the isotope thermoelectric battery to them for specific planning, and explain the required materials. Naturally, there are professionals responsible for the planning of the relevant production line.


    Chen Xin originally planned to work out the design drawings of the production line by himself, but when he was still in the small shelter and the construction personnel confirmed the site conditions, the special team in charge of cooperation with him had already sent the drawn design drawings through the military optical fiber line, and even printed them.


    This is not to say that the country is forced to such an extent that the design drawings can be produced in such a short time. Even if the designers are forced to be bald, they can''t hand in the draft. This is not the problem of determining the scheme, but simply drawing the drawings can''t be done in such a short time.


    As a matter of fact, this drawing is not in-situ, but the design of the production line was started when the state got the sample of isotope thermoelectric battery provided by Chen Xin.


    At that time, the situation was not as bad as it is now. In addition, the country still maintained a certain means of communication, so the technical communication in all aspects was relatively smooth. Naturally, the plan was quickly determined and the draft was produced.


    However, the reverse cracking progress of isotope thermoelectric battery is not so fast, and the key technical indicators have not been determined. Although 10kW samples have been produced in the laboratory, there is still a long way to go before the final production.


    So the drawing has been in the draft state, and did not complete the final details.


    This time, Chen Xin took the initiative to set up a production line. After receiving the news, the special group thought of the drawings of the semi-finished products.


    So it took a little time, at the cost of a few designers pulling out a lot of hair, to improve the design drawings, and sent them through military optical fiber lines.


    Of course, although there are several designers, there are no specific technical parameters. Although this drawing has been improved, it is still impossible to build the production line by this.


    Because there are no specific technical parameters, we don''t know what kind of equipment we should use. We just make do with the equipment, and we don''t know what to produce.


    After all, what they want to produce is isotope thermoelectric battery, which is a dangerous material with high radioactivity. It''s not a "three no" product that black workshops make do with.


    This kind of high-level radioactive product requires high precision in the production process. Any small error is likely to cause radiation leakage or brewing more terrible consequences. So after getting the drawings, the scientific research personnel went to Chen Xin to confirm the process standard of the production line with him.


    However, it''s difficult for Chen Xin. Although he can make isotope thermoelectric batteries, he can also rely on the system''s upgrade ability to make the production line, or directly adjust it to the best state after the production line is laid out, but it''s obviously not a question he can answer to ask him to tell the corresponding process parameters of the production line.


    However, it is not inconceivable that since the state has been able to trial produce a 10kW isotope thermoelectric battery, it is obvious that it will try to trial produce it only after it has a deep enough understanding of the product and technology. Chen Xin can fully learn from their imitated technical parameters.


    Through these data as a reference, first set up the production line, and then Chen Xin through the system upgrade to "debug" the production line, can make the production line to meet the production needs, and even can improve the efficiency of the production line, so that the product yield is higher, avoid waste of materials.


    For Chen Xin to let them directly use the existing data as a reference, which obviously makes the researchers of research institutions feel uncomfortable.


    After all, the establishment of a production line must first determine what products to produce, how much quantity to produce, and the specific process parameters of the products, then it can establish and design the production equipment according to these data, because there is no production equipment that can produce all products in the world, especially the production line.


    The reason why the von Neumann machine in science fiction works is science fiction is that it can produce all kinds of equipment, even copy itself.


    Of course, with the invention of technologies such as 3D printing, universal devices are gradually emerging, but at present, there is no production line that can adjust process parameters at any time and produce any product.


    Different process parameters will result in different products. In order to adjust the process parameters, the whole production line must be modified.


    It takes a lot of resources and time. If it wasn''t for Chen Xin''s ability to upgrade, he would not dare to say that he could do such a thing.


    But Chen Xin''s ability, these researchers also have some understanding. They can understand the reason why Chen Xin can''t come up with the specific process parameters, so they don''t have to say anything more. According to his suggestion, they use the imitation process parameters to design the production line and equipment.


    In fact, these researchers also have their own ideas. In their opinion, they can adjust the production data with the help of Chen Xin, so as to find out why the power of the products imitated by the laboratory before can not reach the level of the samples provided by Chen Xin.After all, the gap between the output power of 10kW and that of 160kW is too big even for technical reasons.


    In addition to the production process parameters, there is a very important thing for Chen Xin to pay close attention to.


    "In this case, how can the equipment on the production line be transported in?" Chen Xin asked the researchers, this is also the biggest problem now.


    After the city government mobilized enough manpower, the site has been gradually cleared up, and the technological parameters have been sorted out with the help of the laboratory. In the later stage, Chen Xin can adjust it. Generally speaking, it is not a big problem.


    But how to transport the equipment to the city, and how to install it in the factory, is a difficult problem.


    Because of the blizzard, all railway flights are now in a state of serious delay. Although trains can still transport things to their destinations, in order to avoid the threat of strong winds, these trains not only walk very slowly, but also need to stop to avoid strong winds. Obviously, they are not a smooth transportation state.


    Under such circumstances, it is very difficult to ensure the coal supply, not to mention free up the transport capacity to transport industrial equipment.


    However, the researchers have only one sentence to answer Chen Xin: "please rest assured that the special team has specially deployed a special train for this purpose, and will bring in all the necessary equipment."

 Chapter 308

    Although there is only one simple sentence that the researchers answered Chen Xin''s question, what it means is the hard work of many people. Train city city is wildly beating gongs and drums in


    , another city in Hunan Province, near Chen Xin''s city.


    The meteorite not only brought dust to block out the sun at night, but also destroyed the railway power supply lines all over the country, so that the country could only take out the old coal-fired steam car head and use it again, while most of the original electric locomotives were lying in their nests.


    Although there are still some fuel locomotives that can be used, because of the shortage of fuel, all these locomotives that can move are deployed to the most critical places to be responsible for the transportation of the most critical materials.


    But in addition, comrades on the railway front have been trying to restore railway capacity.


    Now the train they are debugging is a new one specially researched and developed by Jianning''s railway factory in order to restore railway capacity.


    The car body of the train is specially designed for heat preservation, cold protection, frost resistance and wind resistance, which not only thickens the car body wall, but also increases the stability of the car body.


    According to the original design index, the new car needs to cope with the strong wind of force 10 and the low temperature of minus 50 degrees, but now it obviously needs to face more severe challenges.


    The factory workers adjusted and reinforced it, increased the counterweight for the car body, and replaced the insulation material in the car wall to ensure that it can still have enough insulation effect in the environment of minus 70 degrees.


    Because this train is not only used to transport some valuable materials, but also an attempt made by the state to resume personnel transportation.


    Before the disaster, Jianning was an important train production base in Yanguo. The locomotives produced here were also famous in Yanguo. Even the trains running on the important high-speed railway lines in Yanguo were mostly produced here.


    Therefore, for the workers of Jianning railway factory, they are quite rich in both technology and experience.


    In fact, before the disaster, they had developed a high-speed train that could still operate normally in the low temperature of - 40 degrees. Now they just optimized the technology.


    However, after the disaster, the railway power supply network all over the country was destroyed, and the electric locomotives lost their power supply and could not operate normally. The original advanced electric locomotives were lying down, even if they were not damaged by electromagnetic pulse, they could not operate because of lack of power.


    After all, the servicing weight of an ordinary trunk truck is as high as 240 tons, and the traction power reaches 9600kW. Without the surging power supply, it is impossible to move this giant.


    So the focus of this new car''s debugging is actually the power system of the front of the car, not the carriage.


    Because it is no longer possible to supply power through transmission lines, it is necessary to let the front of the car generate power by itself.


    This is a good thing to do. Whether it''s coal or fuel, it can drive the steam turbine to generate electricity, so as to provide enough power for the whole train.


    However, this time, the new train made by workers of Jianning railway factory is not powered by internal combustion engine, but by small nuclear reactor.


    This is a nuclear locomotive.


    The reactor used is the technology of Yanguo itself, which was originally used in nuclear submarines. However, due to the limitation of technology, its volume has not been able to be reduced, nor can it be applied to trains and civil ships.


    Moreover, the tonnage of nuclear submarines ranges from several thousand tons to tens of thousands of tons. The reactor that can drive nuclear submarines is too powerful for a train. If you want to apply it to a train, you should not only reduce the volume, but also further reduce the power.


    However, this is not an easy thing to do. Apart from the nuclear loading part of the reactor itself, the relevant supporting equipment will occupy a huge space. A cabin is specially designed on the submarine to provide a place for the nuclear reactor. It can be done on a large warship, but obviously the train can''t do it. There is not such a big place.


    But Chen Xin''s isotope thermoelectric battery has given researchers a lot of inspiration and technical support. They have successfully miniaturized the reactor on the original nuclear submarine, improved the relevant technology, and successfully built a small nuclear reactor that can be installed on the train.


    This reactor is not a traditional light water reactor, but a thermoelectric conversion type similar to isotope thermoelectric battery, which directly converts heat energy into electric energy.


    Naturally, there are many advantages in doing so. The radioactive core can be completely sealed to prevent radiation leakage, because it only needs to transfer heat into electric energy, instead of injecting cooling water into the reactor to boil water to drive the steam turbine to generate electricity. Naturally, the former is more efficient in terms of energy conversion efficiency.


    With such a small nuclear reactor, driving a train has become a very easy thing. Even a passenger train''s traction power is more than 5600kW.


    Because the general small nuclear reactor refers to the reactor whose output power is less than 300MW, 1MW is 1000kW, if you want to drive a train, only 10 ~ 15MW power is enough.At present, the output power of the small reactor installed on the new train is 35mW, which can not only drive the train itself, but also provide abundant power for the body for heating, lighting and a series of power needs, including deicing and obstacle clearing.


    The project started three months before the meteorite fell, and the manufacture of the car body started at that time.


    Other parts of the train have made rapid progress. The only restriction is the power system. It was not until Chen Xin provided the state with isotope thermoelectric batteries that the restriction was lifted, and the new train finally successfully stepped down the production line and was about to put into operation.


    The first task of this new nuclear power train is to transport production equipment to Chen Xin''s city.


    It is the special train mentioned in what the researchers told Chen Xin.


    Its successful operation is not only the improvement of railway transportation and transportation capacity, but also marks a more convenient and safe way of nuclear power application.


    The power generated by the small nuclear reactor used on the train is enough to supply all the power of a small county before the disaster. In this case, if a city can have a small nuclear reactor, the power consumption of the whole city will not have to worry, and even the heating mode can be converted into electric heating.


    The reason why Yanguo didn''t do this before the disaster was that there were too many technical problems that could not be solved, and it was too late to build a new nuclear power plant temporarily, so it didn''t use this way to supply power for the refuge before the disaster.


    But now, with safe and reliable small nuclear reactor technology, Yanguo''s top management will obviously not let go of such clean, efficient and convenient energy.

 Chapter 309

    When the new trains arrived in Chen Xin''s city full of production equipment, the blizzard began to weaken miraculously.


    The blizzard, which has been raging for more than half a month, has finally shown signs of calming down. Although the temperature is still more than minus 70 degrees, the wind has dropped from level 12 to level 10.


    It seems that after the violent sweeping of most of the country, this terrible snowstorm has been unable to continue.


    It also gives a glimmer of hope to survivors who have endured the blizzard for more than half a month, although it is not so hard for the city.


    There is no final conclusion on the cause of the blizzard, but according to some information Chen Xin obtained from scientific research institutions, the blizzard should be just a cold wave in the past.


    However, without the regulation of the atmospheric circulation and the heat from the sun, the cold wave did not subside in a short time, but lasted for more than half a month, and it seems that it will continue for some time.


    It''s hard to say that this is good news for Chen Xin, although he has been looking forward to the end of the blizzard.


    Wearing power armor, standing on the platform of the railway station, Chen Xin raised his hand to wipe the snow on his mask and looked up at the end of the rail in his sight.


    There, a train is breaking the snow, like a monster towards the station.


    Before the blizzard, the railway track had been buried by snow. If the train wants to move forward, it must break through the thick snow. This also makes every train running like a car that doesn''t slow down on the waterlogged road before the disaster, splashing two spectacular snow waves.


    Reflected by the headlight of the train, the two snow waves are shining brightly, which looks like the collar of the paralizard.


    However, although it looks gray, and gradually smaller as the train decelerates, it is a symbol of hope in the snowy cold night.


    The train slowly stopped at the platform, and the snow on the platform had already been cleaned up, although it didn''t take a few minutes for the howling cold wind to cover the newly cleaned platform with snow.


    The door opened and several staff members came out, but it was obvious that they had not yet adapted to the temperature difference of nearly 70 degrees between the inside and outside of the car. While they were coated with white frost, they were frozen stiff.


    Fortunately, their clothes were thick enough and their faces were wrapped tightly enough. They soon recovered and said hello to Chen Xin and others on the platform: "Hello, comrade, we are here to send equipment. Who is the comrade in charge of receiving?"


    "I am. Please show me the delivery list." A staff member next to Chen Xin raised his hand and hurried forward to handle the handover.


    While the staff of the two sides are handing over, Chen Xin is carefully looking at the train in front of him.


    Under the platform light, the whole body of the train looks silvery white, and the carriages are similar to the past high-speed trains. Each carriage is closely connected, but there are no windows of high-speed trains on the carriages, making the carriages look more like iron boxes.


    However, from the white gas emitting from the opened door, we can see that the temperature inside the car is not low, and the lights inside are bright. Obviously, the whole car is not short of electricity.


    Chen Xin can''t help but be interested in this and turns to look at the train carefully from the perspective of system upgrade.


    Naturally, Chen Xin discovered that this is a nuclear powered train.


    "Is this a nuclear train? Our country can already apply nuclear reactor to train? " Chen Xin can''t help asking.


    Hearing Chen Xin''s inquiry, a staff member from the train said in a rather proud tone: "yes, this is the first real nuclear powered train in human history. If it wasn''t for the breakthrough in nuclear reactor technology made by the state, we would not be able to realize this amazing idea."


    "Nuclear power train, it''s really amazing!" Chen Xin can''t help nodding in agreement with this view.


    "Comrade, this device on you should also be nuclear powered, right? It seems that the country has indeed made quite an amazing breakthrough in the application of nuclear energy! " Looking at Chen Xin''s armor, the staff members couldn''t help but wonder.


    "This? It''s nuclear power, but unlike the reactor used on the train, I only use radioisotopes. " Chen Xin explained that some people want to get on the train and visit it. After all, it''s a nuclear powered train. Anyone wants to broaden their horizons.


    However, Chen Xin was wearing power armor, and it was a troublesome thing to get on the bus.


    Although there are doors on the car body, because of the weather, the doors are narrower than the normal ones, so as to keep warm and cold.


    Ordinary people can enter normally. If they wear more clothes, they may feel that the door is a little narrow. However, those like Chen Xin who wear power armor can not squeeze in anyway.


    But at this moment, the side wall of a car was opened, and it rose up to the roof like a box, revealing the interior of the car.


    This surprised Chen Xin. It was the first time that he saw a train with "door" opened in this way."Because the car body has enough power, we use this method to open the car, which is also convenient for loading and unloading." The staff on one side explained with some pride.


    In this way, the door opening is more convenient than the ordinary door opening. Whether the goods are in bulk or in bulk, they can be loaded or unloaded more easily.


    Now, for example, because all the sides of the carriage are open, the forklift truck that has been waiting for a long time on the platform directly drives over, forks up the goods in the carriage, directly transports them out, and loads them on the truck on one side.


    Although the forklift used to be used in the past, it is obviously not as convenient as it is now.


    Soon all the goods in the carriage were unloaded, and at the same time, some ready goods on the platform were also loaded.


    These are the finished products of some projects improved by Chen Xin by the scientific research institutions before. Because of the impact of the snowstorm, this batch of goods has been stranded here. Now the special train arrives, so it''s natural to transport them away.


    In addition to this car, other cars are also full of goods, but now the loading and unloading capacity on the platform is limited, only one car can be unloaded at a time.


    So after unloading one car and loading, the second car opened its wall and began to unload.


    Looking at the orderly loading and unloading on the platform, Chen Xin finally couldn''t help but asked the staff on one side, "can I get on the bus and have a look? Is this train more than just a truck? "


    "Of course, we''ve also brought the passenger compartment, but if you want to go up, you may have to take off this iron guy." The staff did not stop Chen Xin from getting on the bus, but said he needed to take off his power armor.

 Chapter 310

    Chen Xin took off his power armor. Although it was cold outside, he didn''t feel cold because he had changed into his special driving suit.


    This driving suit is specially made by Chen Xin for power armor. The innermost part is a layer of close fitting lining. Some of it is similar to the integrated design of dry diving suit. It is breathable and waterproof, and has good thermal effect.


    On the outside of the inner lining, this is the body of the driving suit. Drawing on the design of the exoskeleton protective suit, it is equipped with an electric heating structure, which looks similar to the pilot''s flying suit. It is also an integrated design. A high-performance rechargeable battery is responsible for supplying power to the driving suit. It can be charged by connecting the power supply of the power armor. It can last 48 hours when it is fully charged.


    There are also radio, locator, signal transmitter and other miscellaneous equipment on the driving suit, all powered by batteries, which is enough to ensure that the driver can still survive in the harsh environment after leaving the power armor.


    In addition, Chen Xin specially improved the head structure of the power armor. He designed a light helmet for the driving suit. When driving, the driver can directly put his head into the head of the power armor with the helmet, and then connect it with the power armor through the external connection, instead of directly putting his head into the head of the power armor with his bare head.


    The advantage of this is that it can provide more head protection for the driver, and the driver''s head will not be frozen when he leaves the power armor.


    However, the driving suit itself has no oxygen supply capacity. The helmet only has air filtration function. If necessary, the life support device in the power armor needs to be removed and installed on the driving suit to provide oxygen supply.


    Of course, Chen Xin can''t use these functions now, so he just boarded the train and wanted to have a good look at the nuclear power train.


    Entering from the door, it is a small compartment, connecting the two carriages and separating the interior of the carriage from the door. Its main function is to prevent cold air from entering the interior of the carriage when parking and opening the door.


    The interior of the carriage is not very different from that of the ordinary high-speed railway, but the interior space is relatively compact, and the decoration is not as beautiful and comfortable as that of the high-speed railway. On the whole, it looks more pragmatic, on the contrary, it feels like an old green car.


    But generally speaking, this coach is good enough in the current environment. At least Chen Xin can see that the temperature inside the coach is at least 10 ¡æ through the display on his helmet after he walks in. This is a very comfortable temperature now.


    "Will this train be put into passenger service?" Chen Xin asked the staff on one side.


    At this time, there were only some staff in the carriage. They seemed to be testing the train, and there were no other passengers on board.


    "Not for the time being. Although the state has the idea of resuming railway passenger transport, at present, there is only one nuclear locomotive. The carriage is specially designed for electric locomotives, and the steam locomotive can''t use this kind of carriage." The staff explained and asked Chen Xin, "do you want to visit the power cabin?"


    Hearing what the staff member said, Chen Xin naturally would not miss such a good opportunity. He nodded and followed the staff member through several carriages to the front of the car.


    It seems that the train has put all kinds of functional carriages together for testing, so while Chen Xin follows the staff to the front of the train, he also sees many carriages with different functions.


    "This section is a dining car, which is mainly used to provide food for the whole car. According to our design, as long as the food materials are sufficient, it can provide at least 500 main and auxiliary hot food in an hour. If it is only heated, it can heat 2000 parts in an hour according to the specifications of emergency food in the shelter." The staff are very proud to introduce the situation of the dining car. Obviously, in today''s environment, it is quite practical and amazing to heat 2000 portions of food an hour.


    At least Chen Xin can imagine that if there is a need, just hang a dining car on the front of the car and drag a few more sections of food. Then he can quickly provide hot food for places where there is no food through the railway. This can save many people''s lives at a critical moment.


    In addition to the dining car, there is also a storage compartment on the train. In order to test the function of the storage compartment, there are some food here. It can be seen that it should be the ration of the staff on the train.


    However, what makes Chen Xin feel a little speechless is that the storage compartment is thermostatic. When the outside temperature is high, it will cool down, but now it is actually heating to ensure that the temperature in the compartment will not be too low.


    This point was also introduced to Chen Xin by the staff. Although the external temperature is very low enough to freeze the food in a low temperature environment for a long time, it does not mean that the food can be preserved in a frozen state without doing anything.


    "This storage compartment is not only used to store food, sometimes it will transport some drugs or other important materials that need constant temperature storage, so the temperature must be controllable, not completely ultra-low temperature." The staff explained and added with a smile: "in fact, because the power of the nuclear reactor is too abundant, we will build a thermostatic compartment here. Otherwise, it will not be so wasteful. A small storage box is enough."Chen Xin nodded his head to show that he understood that this is the benefit of nuclear power. With sufficient energy, he can let go in many ways.


    For example, this train has water storage compartment, shower compartment, ecological experiment compartment, sleeper compartment, permanent resident compartment and so on It seems that after they have enough energy, they have completely released themselves. All kinds of ideas have been turned into practical products, and this time they have been dragged out for testing.


    "You There''s a lot of variety. " Looking at such a wide range of cars, Chen Xin can understand the necessity of some of them, but he still thinks that some designs are unnecessary.


    "Most of them are experimental models. If you test them, you may not be able to produce them in mass production, but you should be prepared. If you need them, you don''t need to design them temporarily. You can use ready-made drawings." The staff shrugged, facing Chen Xin''s evaluation, they could only say so.


    Chen Xin nodded, but suddenly thought of something, so he asked the staff, "don''t you want to build a snow train?"


    However, to Chen Xin''s surprise, the staff member really nodded: "we do have such a plan. The train is already under design."

 Chapter 311

    XueGuo train is not only a train, but also a science fiction work. The train itself is the most important stage in this science fiction work.


    In the original work "snow train", the blue star becomes a cold hell for inexplicable reasons. In the end, the surviving human beings are crowded on an endless train driven by a perpetual motion machine. As long as the train stops, human beings will freeze to death, so the train has been moving forward endlessly.


    On the train, the rich live the same life as before. Coffee, tobacco, botanical garden, aquarium, library All these things used to be enjoyed by the rich, while the poor at the bottom live in the last class cars. They can only survive on the protein blocks made of cockroaches. They have to endure the torture of crowding, squalor and hunger, and live a life without dignity.


    This is a quite anti Utopian science fiction work, which describes the huge life differences between the rich and the poor and the polarization of social classes in a very ironic way. It is a quite classic work.


    Of course, this is of little practical significance to the staff on Chen Xinhe''s train. Although the environment of Bluestar is also a hell of extreme cold, even worse than that described in the original snow train, the surviving human beings on the Bluestar have not yet reached the point where they need to be crowded on a train to survive, especially the impossible one with perpetual motion machines West drive train.


    However, the concept of XueGuo train is desirable. In today''s harsh environment, people need railway transportation. It is very important to be able to operate normally in this environment, and XueGuo train is a good reference object.


    "Among the design tasks required by the state, there is a plan for mobile shelters, which is to develop trains that can live permanently or for a long time on the basis of railways, move along the railway lines, transport the survivors from the north to the south where the environment is better, or simply drive along the railway lines." The staff didn''t hide the matter, and it''s not something that needs to be kept secret.


    After thinking about this topic, Chen Xin shook his head and said, "it''s too expensive to drive along the railway. How can you provide enough food for the survivors on the train? The number of people that a train can carry is no more than 1000 or 2000 people.


    Considering the need to carry supplies and ensure survival, it''s amazing that a train can guarantee the survival of hundreds of people, and the cost of keeping the train running is enough to build a shelter that can accommodate more people. "


    "That''s right, but it''s a backup plan. After all, it''s always good to be prepared in case something really needs to be done." The staff naturally understand how much resources it will cost to build a train that can accommodate hundreds of people, but as he said, they prefer to be prepared for use rather than available.


    Chen Xin agrees that there will never be too much science and technology. If someone thinks that science and technology has reached its peak and human beings will not have any new inventions, it will only be that someone''s brain is not working well.


    So for XueGuo train, Chen Xin also gives some suggestions of his own.


    After all, he is a novelist. In some aspects, Chen Xin may not have as much knowledge as scientists, but he is not inferior to those scientists in creativity. Even because of his career, he has more inspiration.


    The staff are also very interested in Chen Xin''s suggestions. After recording some practical ideas, they are very interested in inviting Chen Xin to go to the train manufacturing plant in Jianning when he has time to actually participate in the development and design of XueGuo trains.


    Chen Xin was very interested in this, but he didn''t agree directly. He just said that he would think about it when he had time. After all, he still has a lot of things to do here.


    As for why he accepted the invitation, it was because Chen Xin thought of a more feasible but also more difficult setting from the idea of XueGuo train, that is, mobile base.


    This is a more common setting than the snow train in all kinds of science fiction or fantasy works, many games, novels, comics and film and television works have appeared.


    The small one may be a car, similar to Chen Xin''s own RV, but the big one may be such super large units as Rhode Island, mobile city-state and floating city.


    Small mobile base is easy to realize. In terms of modern technology, it is not too difficult to build it.


    As for the larger mobile base, it is not to say that there is no mobile base. For example, an aircraft carrier can be regarded as a mobile base swimming in the water.


    But in addition to these, it is difficult to build a land mobile base like Rhode Island.


    It''s not that it can''t be built, but that there is no suitable road for such a big thing. Not to mention the structure, materials, shock absorption, energy, life support A series of problems are restricting the emergence of mobile base on land.


    However, these problems may be constraints and troubles for others, but for Chen Xin, they are not problems at all. The big deal is to upgrade the system, which can be created.


    It''s just that Chen Xin turns around and thinks that he doesn''t need to build such a thing, or that he doesn''t need to build such a big one.Mobile base is not a necessity for him. It''s just to take his family to avoid the disaster when there may be an irreparable disaster, so it doesn''t need to accommodate too many people, and it doesn''t need to be built too large.


    So he doesn''t have to build a Rhode Island, just a mobile base car.


    After a few thoughts, Chen Xin didn''t intend to put this idea into practice immediately. After all, mobile base is different from fixed refuge. It involves too many things. Even if Chen Xin can get help and resource support from the state, it is impossible to easily build a shared mobile base.


    However, he thinks that when he upgrades his refuge, he can add some functions appropriately, integrate the structure of the existing refuge, and slowly adjust it to the direction of mobile base. Maybe after several upgrades, it can become a mobile base.


    When Chen Xin was thinking about where he would go when he had a mobile base in the future, he and his staff finally got to the front of the train and saw the nuclear reactor in operation.


    "This is the car''s nuclear reactor. At present, it can provide up to 35mW of output power. Now we just let it run at 70% power." The staff are obviously very satisfied and proud of the nuclear reactor, which is less than the size of a six seat minibus.

 Chapter 312

    After visiting the train, when Chen Xin got off the train, the goods had already been loaded and unloaded.


    After the goods unloaded from the platform are filled with transport vehicles, they will be directly driven away and transported to the small shelter that has been cleaned up now. The staff there will cooperate with the scientific research personnel to install and debug these equipment and prepare for the production of isotope thermoelectric batteries.


    Chen Xin watched the train close the upper wall again after loading the goods, and then slowly drove out of the station. He asked the staff beside him, "where will this train be used in the future?"


    There are so many things that a nuclear powered train can do. No wonder Chen Xin asked.


    "Now it''s just a test run. After this run, it will readjust the carriage and then it should be used for the transportation of emergency and important materials." The staff didn''t know where the nuclear powered train would be used, but he felt that trains that could operate normally in such weather would be used to transport important materials in nine cases out of ten.


    Chen Xin also nodded, did not continue to ask what, just with the staff to get on the car, go to the small shelter cleared out.


    The small shelter is located near the underground factory in the urban area. Originally, it was an industrial area in the urban area. It was mainly an arms factory for the production of clothing and other logistics materials. In the past, it was designed to resume production underground in wartime.


    So three months before the meteorite fell, it was transformed into an underground factory, mainly used for the production of living materials in the city and the processing of shelter food.


    The small shelter is the underground garage of a residential area near the factory area. Now it has been cleaned up. When the equipment arrives, the construction of the production line will begin, and the interior will be rearranged to meet the production demand.


    After all, the more perfect the production line in this small refuge is, the easier it will be to upgrade later.


    After all, he only plans to adjust the process parameters of this production line, not to make major changes.


    When Chen Xin and his staff arrived at the small shelter, all the equipment they brought in first had been put into the space vacated as a warehouse in the small shelter, and some staff were carrying out open box inspection.


    "What about the equipment?" Chen Xin asked one of the staff responsible for checking the equipment.


    "The equipment is in good condition. Thanks to the nuclear power train, there is no sign of freezing damage." The staff reported to Chen Xin with a happy face.


    It''s not unusual for the equipment to be damaged by freezing. Even the metal material is easy to be damaged by freezing at a low temperature of - tens of degrees, and it will lose its original material properties.


    In the past, one of the most important things Chen Xin''s parents did in winter was to freeze the equipment.


    When some scientific research prototypes that need to be upgraded by Chen Xin were transported from other places, the equipment was damaged by freezing or parts were damaged due to low temperature, so this batch of equipment would need to be unpacked for inspection after it arrived.


    These boxes are not ordinary wooden boxes before, but special transport boxes with heat preservation treatment.


    but what happened before the train was awesome, but this time because of the force of the nuclear powered train, the temperature inside the car remained at zero, so there was no problem with the equipment coming all the way.


    "That''s good. Get all the equipment ready as soon as possible and speed up the site construction." Chen Xinjian didn''t have any problems with the equipment and didn''t talk too much. He just asked the staff to get everything ready as soon as possible so that they could install the equipment earlier and put the production line into use.


    "Don''t worry. We''ll be watching all the time. We won''t delay." The staff also know the importance of things. In fact, during this period of time, they also work in shifts and stare here round the clock.


    After getting out of the small shelter, Chen Xin and several researchers returned to the Institute of technology by car. Because the small shelter was not connected to the underground road, they had to walk from the ground by car.


    The snow on the ground and the strong wind make it almost impossible for the car to move, but they only need to drive to the nearby underground factory to be able to return to the Institute of technology through the underground road, which is not a few steps away.


    "Have you sent the drawings of exoskeleton protective clothing to the research department?" On the bus, Chen Xin asked a scientific researcher about the drawing he had asked them to hand over.


    "The drawings have been sent through the military network, and the other side said that it would start research and production immediately. I believe there should be results soon." The researchers quickly answered to Chen Xin that they dare not neglect anything about Chen Xin, especially such important things.


    Although they were very envious of Chen Xin''s power armor and wanted to carry out research, Chen Xin never gave them samples, and they were embarrassed to ask for it, but they didn''t expect that Chen Xin turned around and gave them a design of exoskeleton protective clothing.


    As for the design drawing, they have evaluated that as long as the weather is not as bad as before, the protective clothing can provide good protection, and the exoskeleton can also be used as an engineering aid, which can play a considerable role in the post disaster reconstruction of the whole country.In fact, these researchers do not know that they have shocked the top leadership of Yanguo after they submitted the drawings.


    In the view of the top leadership, such a suit of exoskeleton protective clothing is worth promoting. It can completely change the situation of Yanguo, even the situation of Bluestar.


    When the disaster came, all the countries and forces of the whole blue star were greatly impacted. Basically, small countries were killed, and there were not enough resources and national strength. In the face of this devastating natural disaster, they were completely destroyed.


    Yanguo, as one of the top five hooligans, is in the best situation. At least most of its citizens have been saved. At present, the areas under actual control have not shrunk too much. The army is well preserved and production is recovering.


    Although the blizzard caused severe damage to the whole country, many people who survived died because of the cold, and many important construction projects were also affected, the reconstruction work still did not stop.


    Although this suit of exoskeleton protective clothing does not look very impressive, it can actually improve the progress of the reconstruction work, and also enable more people to have the ability of outdoor activities, which plays an immeasurable important role in the whole reconstruction plan of the country.


    And that''s enough to make Yanguo the first country to recover from Bluestar.

 Chapter 313

    A series of disasters caused by meteorite impact are irresistible natural disasters for small countries.


    The countries in Europa are good. Although the governments of small countries are unable to cope with the disaster, and even before the impact of the meteorite, the order of these countries collapsed because of the social chaos, at least these countries were not directly flattened by the tsunami as in the Nanyang region, and a large number of people survived the first wave of disasters by self-help.


    But in these places, it is very difficult to survive because of the lack of government organization and adequate response. The survivors of these countries have to rely on themselves to collect available materials from the ruins. They need to face all kinds of dangerous environments. Not to mention, they also need to fight against other survivors. Every day is very difficult.


    If we prepare for the doomsday before the disaster, we can still have some coping ability in the face of such a disaster, but the vast majority of ordinary people who do not have such preparation can only hold their heads and wait to die.


    On the one hand, their government collapsed long before the disaster because of the social chaos brought about by the doomsday panic; on the other hand, these ordinary people have no skills to survive in the end, and most of them may not even be able to avoid the first wave of disasters brought about by the meteorite impact.


    In these areas, perhaps only those who are truly apocalyptic can survive?


    The situation of big countries is relatively better. At least these countries have the ability to build shelters and military bunkers in peacetime. Even after a disaster, they still have certain military strength and organizational structure, and they can organize a group of social elites to hide in the shelters and survive the initial disaster.


    In the aftermath of the disaster, these countries also have the strength to resume production.


    Moreover, for these Europa countries, without the need for high welfare and the burden of various opinions, they are more able to take part in the reconstruction of their own country with some social elites as the main body.


    Of course, such an elite model also has problems. Without a large number of grassroots people, it is bound to bring problems such as insufficient labor force and slow development. However, with fewer people and less burden, it is better to slow down than to collapse as a whole.


    After all, there are essential differences between Europa and Indonesia. Their people''s obedience and the government''s control over the country are not as good as that of Indonesia. In the case of being unable to restrain ordinary people, elite groups are more suitable for these countries.


    If there are several other countries in the world that can keep their vitality in the face of disaster and start to rebuild quickly after the disaster, on the blue star, there are only three big countries, namely, Japan, the Federation and Lucia.


    The other two countries of the five hooligans have already degenerated to the point that they are no different from the ordinary big powers in Europa. In peacetime, they may still have some strength, but in the face of such a doomsday disaster, which is an extreme test of their comprehensive national strength, they can hardly do anything.


    Among all the countries, the situation of Yan state is the best after the end of the world, because there are a large number of people and a wide range of land. There are not only a large number of survivors as the labor force after the disaster, but also enough places to build shelters. At the same time, a large number of materials and means of production before the disaster are preserved, so that production can be quickly restored and reconstruction work can be carried out after the disaster.


    And Lucia''s words, although the country has long been in decline, and even the dignity of a big country is just struggling to maintain, but the original red polar bear left behind a rich legacy, even if it has been dead for decades, Lucia also ate the legacy for decades, still let Lucia have the courage and strength to deal with the disaster.


    If you understand the history of Lucia, you will know that this country needs an iron hand ruler. Every generation of famous kings or rulers in the history of Lucia is a symbol of iron hand and power.


    Therefore, in the face of this disaster, what Lucia lacks is not the strength to deal with the disaster, but a strong enough ruler to control the country and rebuild her home after all the resources and means to survive the disaster.


    At the beginning, Lucia was able to rebuild a superpower from the ruins and embers after World War II. In fact, they did not lack the possibility and opportunity to rise. All they had to do was to see if they could have a leader who could control the country.


    As for the first power Union on the blue star, the situation is somewhat complicated.


    When the meteorite fell, a meteorite flew to the federal territory, and the federal launched a nuclear bomb to block it, but the result was not ideal.


    The meteorite still fell on the west coast of the Federation, and the whole west coast was destroyed. Although it was not the worst result, it crashed into Yellowstone volcano and exploded the volcano. The result was not too bad.


    After all, the nuclear bombs launched by the Federation with radiation have spread over most of the federal territory with meteorite debris and dust, making the Federation enter the end of wasteland.


    Moreover, because of the unique regime of the federal government, after the disaster, the federal government has lost its control over the States. Only a few states close to the capital still reluctantly follow the instructions of the federal government, but they just listen, not obey.


    As for the other states, the West Coast states have completely become dead places. If there were no Rocky Mountains to stop them, I''m afraid the central region would fall with them.


    Now, thanks to the existence of the Rockies, the impact of the meteorite impact and the subsequent secondary disasters, as well as the radiation dust generated by the previous nuclear bomb explosion, the central and eastern parts of the Federation east of the Rockies have been preserved, but they have fallen into a state of separation.Florida and other southern states formed the Confederacy, while New York and other northern states still belonged to the Federation in name, while Wisconsin and Minnesota in the five Great Lakes region formed an independent but loose union to fight against the original Federation.


    Central states like New Mexico and Texas have become independent, but their situation is different.


    The painting style of these States, which are influenced by their ethnic, cultural and traditional customs, is different from that of other states in the Federation. The people of Texas, who have strong folk customs, have long had the idea of independence, and most of them do not obey the local state government very much.


    So after the doomsday disaster, the survivors of these places quickly formed a small group. They did their own things, but they also started fighting with each other, which almost turned the whole central plain of the Federation into a war zone.


    If it wasn''t for the cold weather, these areas would be engulfed by ice and snow. Coupled with the desertification terrain, it really feels like waste soil.


    These situations have greatly hindered the ability and progress of the Federation in post disaster reconstruction. Although a considerable part of the strength of the Federation has been preserved, these forces have been scattered and cannot be concentrated.


    Now, all countries have stood on a new starting line again. Some are leading, some are lagging behind, and others are starting again. Who can really take the lead in the new world after this disaster depends on who is the first to break free from the disaster.

 Chapter 314

    If you want to take the lead in the game after the disaster, post disaster reconstruction is undoubtedly the most direct thing that can affect the result of the game.


    When it comes to post disaster reconstruction, human resources are undoubtedly one of the most important resources. After all, no matter what the post disaster reconstruction project is, it cannot be separated from the fundamental factor of human.


    In today''s bad weather, it is very difficult for ordinary people to carry out activities in the outside world, let alone work. The low temperature of tens of degrees below zero is enough to freeze anyone who is not well protected. Even if there is enough protection, it is easy to freeze a layer of ice on the body and hinder activities.


    Therefore, it''s normal for protective clothing that can cope with harsh environment to be popular at this time, not to mention the exoskeleton protective clothing that Chen Xin brought out has mechanical assistance, which can fully enable workers to maintain sufficient labor ability in harsh environment and maintain the work efficiency of post disaster reconstruction.


    This is also the reason why only a piece of exoskeleton protective clothing can alarm the top leaders of Yanguo, because it really has quite important strategic significance.


    The things that can influence the national strategy are not as big as many people think. Most of the time, they may be the gadgets that can be seen everywhere in our lives, but they can affect the national economy and people''s livelihood.


    However, although Chen Xin has provided such an important thing to the country, he is still focusing on the construction of isotope thermoelectric battery production line.


    Compared with the drawings of exoskeleton protective clothing submitted to the state, Chen Xin also submitted the drawings and samples of isotope thermoelectric battery to the state, but it is obvious that the technical contents of the two are quite different.


    Exoskeleton protective clothing is a kind of similar product that can be made even if it can''t be made with drawings. But isotope thermoelectric battery is something that can''t be imitated with drawings, samples or even technology.


    Otherwise, ah San won''t be able to get other people''s aircraft production line and have hands-on teaching. The aircraft he builds will fall dozens a year.


    So Chen Xin of exoskeleton protective clothing can confidently and boldly hand over the drawings to the state for imitation, but if he wants to use isotope thermoelectric battery urgently, this production line will be built anyway.


    Fortunately, with the investment of the state and the small scale of the production line, it is not a problem to build it.


    After the arrival of the equipment, with the supervision of scientific researchers, the construction progress of the site is not slow. Each plant has been basically completed, and Chen Xin has also sent the isotope generator, which is the power source of this refuge, and has entered the stage of installation and commissioning.


    "Are you really going to install this generator here?" The old professor who came to install and debug the generator with Chen Xin looked at Chen Xin wearing power armor and checking the generator with a mechanical arm. He asked Chen Xinfa if he didn''t agree.


    In the old professor''s opinion, the technology involved in this generator is too important. It should be thoroughly analyzed in the laboratory, and put into practice after the technology is thoroughly studied, rather than being directly transported to install the generator for power generation.


    To this point, Chen Xin just shook his head and said: "in the laboratory, it''s just a good-looking object. Although technical analysis is important, I think it''s better to let it play its original function and practical value first, and then consider what the scientific skills it contains bring."


    This is the difference between Chen Xin and the old professor. According to the old professor, we should first analyze the technology of isotope generator, and then use these technologies to promote the development of science and technology and benefit the whole country and even mankind. However, Chen Xin will first use isotope generator to generate electricity and play its essential role.


    Of course, there is no right or wrong between the two attitudes, but the choice and focus are different.


    The old professor didn''t have to ask Chen Xin to give him the isotope generator for analytical technology, and Chen Xin didn''t stop the old professor from studying the isotope generator.


    "But speaking of this, you have done some research and Analysis on this generator before. Do you have any clue?" Chen Xin adjusted the generator and connected it to the circuit of the small shelter. At the same time, he asked the old professor.


    The isotope generator has been put in the Institute of science and technology before, and it was studied and analyzed by old professors and other researchers, trying to analyze its related technical principles.


    However, time is so short that it is almost impossible to find anything. Therefore, Chen Xin only asked the old professor if he had any clue or ideas, not what he found.


    "At present, there is a little clue, but the weak nuclear force is still too early for human beings. To study it, we need to complete too much theoretical basis." This is also the main reason why the old professor did not object to Chen Xin''s direct use of isotope generators for power generation.


    Because the theoretical basis is too poor, even if some phenomena are found, it is very complicated and time-consuming to analyze the knowledge contained in them.


    Chen Xin was not surprised by this, but after thinking about it, he said: "if it''s too troublesome for you to analyze the generator, I think you can start with the battery. The isotope generator uses the isotope temperature difference battery as the charging material. It should be easier to study this first. Moreover, the state is also studying this aspect, and has made certain achievements and made great achievements It''s an imitation. ""I''ll think about it, but there''s no choice for scientific research. It''s impossible not to do research because of the lack of theoretical basis." The old professor''s attitude was very firm, and he didn''t change his mind because of Chen Xin''s persuasion.


    Chen Xin didn''t insist on this either. He just said to the old professor, "after the production line of isotopic thermoelectric battery is completed, I will build another production line of isotopic generator. Although I can''t tell you the technology, I can still make things. At that time, you can take one of the products to study."


    "Can you make a production line for isotope generators?" The old professor felt a little incredible, but when he recalled seeing Chen Xin upgrade his isotope generator, he nodded slightly and said, "with your ability, you should be able to do it. It''s really enviable. Acquired scholar syndrome is totally equal to ordinary people''s diligent study all their lives! If it is not impossible to explain the principle of this disease, I am afraid everyone wants to get this disease? "


    "Who can say that well? And it''s not sure what kind of ability this disease will acquire. Some people may be proficient in eight foreign languages, others may be proficient in advanced mathematics without a teacher, and some may be able to play all musical instruments directly. The human brain is wonderful. " Chen Xin said half seriously and half perfunctorily.

 Chapter 315

    While the construction of the production line of the isotope thermoelectric battery is progressing steadily, the municipal government is also organizing people to open up the underground access from the underground factory to the small shelter.


    After all, the temperature outside is dozens of degrees below zero, and the snow is more than one meter deep. If people don''t step on it well, they will sink directly into their chest.


    In this case, outdoor is not suitable for survival and activities, so instead of the trouble of walking on the ground, it is better to directly open an underground passage.


    These things naturally have the responsible staff to deal with, and Chen Xin himself finally has time to go to Mo Qingyan''s home with Qin LAN to see the situation.


    In fact, there is nothing to see. Under the storm of minus 70 degrees, the original small building of Mo Qingyan''s family has been completely engulfed by the snow, and the antenna that should have been erected on the top of the building has already been blown so that they don''t know where to fly.


    Chen Xin and Qin LAN stepped on the snow and arrived at the fence of the yard. If it wasn''t for the heavy power armor, their lower bodies were completely immersed in the snow. With the thickness of the snow, they only need to lift their legs to get into the yard.


    But now it''s not too much trouble, holding the top of the wall with both hands, you only need to use a little force to turn over the same.


    Chen Xin and Qin LAN went inside without much effort. However, there was no big difference between inside and outside Mo Qingyan''s courtyard. They were also completely buried by more than one meter thick snow. The original elevator was completely engulfed by the snow. They could only see a little bulge on the ground, but there was no elevator under the snow.


    "It seems that we need to take the stairs." Qin LAN looked at this situation, helpless to Chen Xin said.


    Chen Xin also nodded. In this case, even if the elevator is not damaged by freezing, they don''t need to dig it out of the snow. It''s more convenient to take the stairs directly.


    Although Mo Qingyan''s family mainly relies on the elevator to get up and down, it''s not that there are no stairs to go down. After all, no matter how to build the underground shelter, it''s not enough to say that only the elevator is left.


    The two spent a little effort to find the stairs from the inside of the vacant building, but this time it was not Qin LAN who hit the door, but Chen Xin who used the universal mechanical arm to pry the lock.


    With the help of the universal manipulator, Chen Xin quickly opens the door and enters Mo Qingyan''s refuge with Qin LAN.


    Before the disaster, it used to be a bar. Just like the gym in the upper building, it was only open to members. Chen Xin and Qin LAN used to come here.


    When they were still dating, they were frequent visitors here, but later they broke up and never came together again.


    However, they came here to find Mo Qingyan quite a lot, so they are familiar with both Chen Xin and Qin LAN.


    In the past, the bar has been transformed into a warehouse by Mo Qingyan. There are a lot of food reserves in it, but now most of them are frozen.


    "I remember our first date here, right?" Chen Xin suddenly opens his mouth to Qin LAN and mentions the past.


    Qin LAN looks at the bar that has changed its face, remembers the scene of their first date, and has the feeling of revisiting their hometown. She nods her head and says, "you were more likable then than you are now."


    "People always change. Just like here, they have changed completely." Chen Xin shook his head and sighed. He and Qin LAN went through the frozen boxes on the ground and continued to walk down.


    When they came downstairs, they saw Mo Qingyan''s wine cellar. It was a pity that the wine cellar had been frozen because of the low temperature.


    "If Qing Yan sees her wine cellar become like this, she should cry." Qin LAN knows how precious Mo Qingyan is. The reason why she has a bar upstairs is for these treasures.


    It took her a lot of hard work to build this wine cellar. Now it''s all frozen up. If Mo Qingyan sees this scene, she can imagine her mood.


    "It''s just frozen. I should be able to save it. But don''t move now. I''ll wait for longniang to deal with it." Chen Xin did not rush to move the frozen wine cellar.


    All the wine in it is mo Qingyan''s treasure. Maybe it can be saved now. If Chen Xin breaks them, it can''t be saved.


    Qin LAN heard Chen Xin say so, also did not say much, nodded and Chen Xin continued to go down.


    The situation of the lowest refuge is better than that of the upper two. Because of the ground source heat pump that Chen Xin installed for Mo Qingyan before, the temperature is not too low. Coupled with the barrier of the upper two layers and the thick snow on the ground, the temperature here is not too low to be acceptable.


    At least when Chen Xin and Qin LAN came down, the sink on the fish and vegetable symbiosis equipment connected to the ground source heat pump was not frozen. Although the fish in it were not very active, they were still breathing around the heating tube, without tumbling or dead fish.


    The dishes on the sink are frosted, and the leaves are covered with white frost. It seems that they should be eaten as soon as possible.


    Seeing this situation, Chen Xin and Qin LAN feel relieved when they come here. At least Mo Qingyan hasn''t turned into the worst state here. Although it looks terrible now, the loss is not big and the place can still live."The temperature here is very low. It seems that if long Niang wants to come back to live, she has to upgrade the heating again." Chen Xin was born in power armor. He kept his body warm by the electric heating of his driving suit. He wandered around Mo Qingyan''s house to check the things here.


    Mo Qingyan''s air conditioning, television and other electrical equipment have a layer of white frost. You can see that the frost is very thick when you rub it with your hand.


    Obviously, the low temperature has caused great damage to these electrical equipment, but it is obvious that these equipment can no longer be saved. Chen Xin just looked at them and gave up the possibility of repairing them.


    Chen Xin tried to press the start button, but there was no response: "the air conditioner should have been damaged. It seems that long Niang wants to come back to live. A lot of things here have to be changed."


    "It''s better than scrapping it directly here, and compared with air conditioning, I think ground source heat pump may be more practical." Qin LAN took a look at the air conditioner that could not be started and the ground source heat pump that was still in operation. There was no need to judge which was better: "Xin, do you want to help Qing Yan repair this place?"


    "She has this need. Let''s say that first." Chen Xin shakes his head and doesn''t have the idea of helping Mo Qingyan repair her home now: "it''s estimated that long Niang won''t come back to live for the time being, and Ding Ning can''t come back either. Let''s put it here first. After all, it''s a big project to repair it. Let''s wait until the snowstorm is over and consider these things."

 Chapter 316

    The blizzard that has been raging for nearly a month has finally subsided, but even so, the temperature has not picked up.


    The cooling brought by the snowstorm is an instantaneous process, but now without the sun, it is a very long process for the temperature to rise.


    However, after the blizzard stopped, the temperature rose from - 70 degrees below zero to - 60 degrees below zero. It is not easy to rise more than 10 degrees.


    "According to the forecast of the meteorological department, the temperature should be able to rise to about - 50 degrees below zero, but this is already the limit. Unless the dust in the sky is dispersed, it is difficult for the temperature to rise again." The researchers explained to Chen Xin the weather forecast made by the meteorological department and gave him a detailed analysis report.


    Chen Xin took over the report. Although he didn''t know most of the professional terms above, he still read it carefully and said, "it seems that the weather can only be like this now. Does it affect our subsequent construction?"


    "There will certainly be an impact, which is inevitable in the current environment." The researcher sighed helplessly, and then continued: "the meteorological department has calculated the current environment with the help of supercomputer. In the current situation that the world is in extremely cold weather, even if the dust in the sky is dispersed and we get light again, the cold weather will last for hundreds of years or even thousands of years before it can be relieved.


    Therefore, construction in cold weather is a problem that must be faced at present and even in the future. Even if there is an impact, we can only find a way to overcome it. "


    To this, Chen Xin can only nod his head: "unless we build a dome city like in science fiction, cover the whole city with a cover, and then raise the ambient temperature in the dome, otherwise this low temperature weather can not be avoided and changed."


    "Dome City..." Hearing Chen Xin''s words, the researchers shook their heads: "that''s really beautiful, but we can''t make it now!"


    The dome city is certainly beautiful, but if you want to build a dome that can cover the whole city, the requirements for materials simply break through the sky, which is far from the level of science and technology that human beings have now.


    Even if Chen Xin has the ability to upgrade the system and wants to build a dome City, it is not easy to do. The survival cost of upgrading a city alone is a number that Chen Xin can''t afford.


    But the dome city can''t make it out. Other things are possible.


    "As for the drawings of exoskeleton protective clothing submitted by me, has the state arranged for production?" Chen Xin asked the researchers that he didn''t want his hard work to be shelved.


    Hearing Chen Xin''s question about the exoskeleton protective clothing, the scientific research personnel quickly replied: "about this, the country has been organizing the production, but I heard that the exoskeleton and protective clothing are produced separately."


    "Separate production? Why? " Chen Xin is a little strange. He doesn''t understand why he should take apart a good suit of exoskeleton protective clothing.


    "It seems that there are still some technical problems to be solved in the production of exoskeleton, and the national side thinks that protective clothing needs to be spread out first." Researchers don''t know much about it, but they can still understand how it is.


    The exoskeleton is obviously more complex and requires higher technology than the protective clothing which only adds metal wire to the clothes to obtain the heating function.


    Besides, there is also a key part, that is, the high-performance battery used for the function of the exoskeleton. This thing, together with the control system of the exoskeleton, is the core of the whole exoskeleton. If these two parts can not be manufactured, the exoskeleton is just a pile of empty shelves and has no practical application value.


    In these two parts, the control system is just a matter of chip and programming. With the system template on the sample provided by Chen Xin, it''s not very difficult to copy a set of system according to a gourd''s brush, but it takes time for high-performance batteries to decipher how the contents of the batteries are made.


    However, it is obviously impossible for the state to produce exoskeleton protective clothing after all the technical problems have been solved. Therefore, it is a natural choice to split it up and produce some protective clothing which is easy to manufacture to meet the needs of the shelter residents.


    Chen Xin quickly understood why the state did this, but didn''t say much. Instead, he asked the researchers about the installation progress of the production line: "what about the installation progress of the production line? How soon will it be finished? "


    "The site construction has been completed, all the plants have reached the national standards, and the equipment is being installed and debugged. All the installation work can be completed this week, and the equipment debugging will start next week." The scientific research personnel took a look at the record book in their hands, confirmed the progress again, and then reported to Chen Xin.


    However, after that, the researchers also asked with concern: "at present, we are using the process parameters sent by the laboratory. They have developed a 10kW isotope temperature difference battery according to this process parameter. It should be no problem to produce according to this process parameter, but the power of the battery is estimated to be very unsatisfactory.


    Although there is also the idea that we can adjust the process parameters through trial production, I don''t think we should waste too much resources on this. The key is to adjust the process parameters as soon as possible and produce products that meet the requirements. ""Don''t worry, I already have a plan for this. When all the equipment is installed and debugged, I will adjust the existing process parameters of the equipment, and then start the first production." Chen Xinchong''s scientific researchers are making a guarantee that this is what he plans to do.


    The researcher nodded and recorded this in his notebook. Then he continued: "as for workers, the municipal government has assisted us in recruiting a group of workers. They are currently receiving training. They should be able to take up their posts when the equipment debugging is completed."


    "We must pay attention to safety issues. Standards can only be high, but not low, so as to eliminate any possible safety accidents." Although Chen Xin himself can rub isotope thermoelectric batteries with his bare hands, he doesn''t think other people can do the same thing.


    In particular, a large number of radioactive materials are used in the production process of isotope thermoelectric battery. Any radiation leakage or pollution accident will cause very serious consequences, so the safety problem can not be overemphasized.


    "Please rest assured that we also attach great importance to safety issues and will definitely eliminate all hidden dangers." In the face of this problem, the scientific research personnel also have a positive face and solemnly guarantee to Chen Xin.

 Chapter 317

    When the snowstorm stopped and Chen Xin came out of the shelter to the surface, he was surprised to feel the clarity of the sky.


    Although there is still thick dust blocking the sun, when Chen Xin looks up, he feels that the air under the dust is very clean.


    This is a very contradictory feeling, but very easy to understand.


    Because of the blizzard, the dust and other particles in the air are blown away by the strong wind above level 12, so it''s not unusual for the air to look clean and clear when the strong wind stops.


    This is why many people say that the weather will get better after rain or strong wind, because the dirty things in the air are taken away by rain or strong wind.


    However, the atmosphere is stratified, and the disturbance of the lower atmosphere is difficult to affect the upper atmosphere. The dust and particles suspended in the upper air are the main factors to block the sunlight from shining on the ground, and they are not affected by the snowstorm.


    This is why when Chen Xin looks up, he can still see the dark sky, but he can also feel the clarity of the sky.


    "The snow has finally stopped!" Chen Xin and Qin LAN came to the outdoor again. Looking up at the snow in the sky, they could not help but take a breath.


    "Yes, it''s finally stopped. If it doesn''t stop, I don''t know how many people will die because of the snow." Qin LAN can''t help sighing.


    Before, Qin LAN followed Chen Xin to various shelters and met many people who had been frozen to death because of low temperature, which made her feel very uncomfortable.


    Now that the snow had stopped, she let go of her worries about the survivors of other shelters.


    "The storm is over. Everything will be fine." Chen Xin knows what Qin LAN is feeling. For those who have frozen to death, Chen Xin also has a heavy heart, but he values those who are alive more.


    The dead have died, which is irreparable. We can''t do more for the dead than mourn and mourn.


    But the living people still have to live. We can do something for them to make them live better.


    "Well, everything will be fine." Qin LAN looks at Chen Xin and nods her head seriously.


    Her confidence is not in the world, but in Chen Xin. She believes that Chen Xin will make everything better.


    "Let''s go back. We''ve been out for so many days. We don''t know what''s going on at home." Chen Xinchong and Qin Lan said, with a bitter smile on her face: "after so many days away from home, I don''t know what''s going on at home. My parents may be worried again."


    However, Qin LAN shook her head this time and refused to say to Chen Xin, "ah Xin, go back alone. I have something to deal with, so I won''t go back with you."


    "What''s the matter? What''s the matter? " Chen Xin is not surprised that Qin LAN does not go back with him, but he habitually asks.


    "In the team, when I hurt my hand, I was already out of the front line, but there has been no formal procedures. I want to formally resign from the police force." Qin LAN explains to Chen Xin why she wants to stay alone.


    Chen Xin looks at Qin LAN. Although she looks calm on the surface, Chen Xin knows that her heart should be very excited at this time.


    As Qin Lan''s ex boyfriend, Chen Xin understands how much effort Qin LAN has made to be a good policeman. It can be said that being a policeman is Qin Lan''s ideal in life and her biggest goal and pursuit in this life.


    But now she said that she wanted to put an end to this matter. Obviously, she made such a decision with great determination.


    But Chen Xin didn''t persuade Qin LAN or interfere in her decision. He just nodded and asked, "do you want me to accompany you?"


    "No, I want to deal with it alone. Go home first. My uncle and aunt must be worried about you." Qin LAN shook his head, and did not let Chen Xin stay.


    "Well, if you need me, please let me know." Chen Xin can only say this, which can be regarded as a promise.


    "Well, I''ll ask you for help." Qin LAN doesn''t want Chen Xin to help, but she doesn''t refuse his kindness. She just agrees, but she doesn''t intend to ask Chen Xin for help.


    Chen Xin, of course, saw that Qin LAN didn''t want to ask for help, but he didn''t force it. After a few words with Qin LAN, he turned and walked towards his home.


    Because of the blizzard before, the snow outside was thick and deep, and most of the entrances and exits of the shelters were covered with snow. Now they are in the process of cleaning up, so it is almost impossible to take a car. Chen Xin has to walk back on his own just as he did when he came.


    Looking at Chen Xinyuan''s back, Qin LAN has been watching his figure disappear. Then she turns back to the shelter and plans to deal with her own affairs.


    Because of the absence of snow and wind, Chen Xin''s journey home did not encounter any obstacles, but when he returned to his home, he could not find his home.


    The thick snow has completely buried the whole shelter, and no trace can be identified. Even the observation room, which was still prominent, has disappeared under the snow."It seems that I have to dig out my own house?" Feeling helpless, Chen xinlue uses the radio to contact Han Ping and Han Ze brothers in the shelter to open the door from the inside, controls the universal mechanical arm on his power armor to sweep away the snow in front of him, and uses the metal detector to find the exact location of the gate of the shelter.


    Han Ping and Han Ze are obviously always in front of the radio station and receive Chen Xin''s communication. Han Ze''s excited voice soon spread out: "Mr. Chen, are you back?"


    "Yes, the Blizzard has stopped, so I came back. Is everything OK at home? The gate is completely covered with snow. Open the door from inside and dig a way up Chen Xin tells Han Ze his instructions, but he doesn''t stop trying to find the gate of the refuge.


    Without power armor, Chen Xin may find it hard to find his own gate. After all, after the snowstorm, even the topography has been changed. It''s obviously not an easy job to find his own gate. It''s hard to find the location of his own gate without digging up all the snow.


    But fortunately, he has a universal manipulator. Through the metal detection and echo location of the manipulator, Chen Xin quickly found the door under the snow.


    In addition, Han Ping also opened the door from the inside according to his instructions, and dug out with Han Ze, so Chen Xin quickly dug out the snow, joined Han Ze and Han Ping who dug out from the inside, cleared the snow in front of the gate of the refuge, and returned to his home.

 Chapter 318

    Together with Han Ping and Han Ze, Chen Xin cleans the snow at the gate and closes the gate of the shelter. Chen Xin returns to the shelter and takes off his power armor.


    "Mr. Chen, you are back at last!" Han Ping is a little excited when he sees Chen Xin coming back. The shelter is blocked by snowstorms these days. He has been worried about Chen Xin''s safety and regrets that he didn''t go downtown with him that day.


    Now that Chen Xin is back, he puts down his worries about Chen Xin. After all, as a bodyguard, he should be with the target who needs to be protected.


    "How is everything at home? Nothing wrong? Where are my parents? " Chen Xin shrugged, took off the helmet of his driving suit and asked Han Ping.


    "Everything is fine here. Although you were trapped by the snowstorm before, the shelter can be self-sufficient, so there''s no problem. Your parents are all down here." Han Ping soon recovered his mood and answered to Chen Xin.


    Chen Xin nodded, patted Han Ping on the shoulder and said, "if it''s hard for you, nothing''s wrong. I''ll go down to see my parents first. You two should do your own business first."


    With that, Chen Xin went to the elevator.


    He took the elevator to the lower floor because he had learned from Han Ping that Chen Xin had come back. His parents and Mo''s sisters were waiting for him to come back.


    "Mom and Dad, I''m back." Chen Xinchong greets his parents and smiles at the Mo sisters.


    "Just come back, where''s Xiao Qin? Didn''t come back with you? " Chen Xin''s mother sees that Chen Xin is the only one and asks about Qin LAN.


    Although Chen Xin and Qin LAN have broken up, when they were together, Chen Xin''s mother had regarded Qin LAN as her daughter-in-law.


    When they broke up, Chen Xin''s mother was a pity that such a good daughter-in-law was gone. Now they are getting together again. Chen Xin''s mother is very concerned about them. She hopes that they can get together again, and she can have grandchildren as soon as possible.


    So see Qin LAN did not come back together, naturally also very concerned about this matter.


    "Ah LAN has something else to do in the city, so I came back first." Chen Xin explained that he was concerned about his parents and asked, "Mom and Dad, have you nothing happened these days? How are you at home? "


    "Everything is fine at home, except for a little cold, nothing else. You''re tired when you come back. Go wash and have a good rest Chen Xin''s father nodded slightly. Seeing that nothing had happened to his son, he put down his heart. After two sentences, he turned around and left with Chen Xin''s mother.


    Seeing his parents leave, Chen Xin looks at Mo Qingyan and Mo Qingxin, greets them and asks, "Hi, two beauties, are you used to living in my house?"


    "Not bad. It''s time to harvest vegetables this month. The other chickens are also growing well. The hens started laying eggs two days ago." Mo Qingyan is still a little cold, but after answering Chen Xin''s question, she told him: "before, my uncles and aunts were worried about you. If nothing happened, don''t run around. Uncle and aunt are so old. If something happens to you, how can you make them bear it? "


    "I see. Thank you for your concern." Chen Xinchong and Mo Qingyan smile, which means that they remember what she said.


    In the face of Chen Xin''s attitude, Mo Qingyan can only nod her head, without more expression.


    Instead, Mo Qingxin asked Chen Xin with great concern: "ingredients, what''s the situation in the urban area now? Before such a big snowstorm, the situation in the urban area should be very serious, right


    "The situation in the city is really serious. Almost all the places are covered with snow. There are frozen people in several official shelters I went to." When it comes to this issue, Chen Xin''s face is also a little heavy: "fortunately, it has survived now. When I came back, the municipal government had been organizing self rescue and production recovery after the disaster."


    "Is it freezing to death? How serious it is When Mo Qingyan heard Chen Xin say that people in the city were frozen to death, her face changed.


    Although she knew the severity of the blizzard, because Chen Xin had taken enough cold prevention measures here, and used ground source heat pump to keep the temperature at a level that human body could bear, Mo Qingyan felt that the situation in the urban area should not be worse. However, she did not expect that Chen Xin''s mouth was frozen to death in the urban area, which greatly exceeded her expectation.


    Chen Xin nodded heavily, then continued: "the problem of low temperature is quite serious. We have ground source heat pump here, but it''s not a big problem, but the power of the boiler in the city is not enough, so the temperature can''t rise. Before I went to the city, the temperature of many shelters was more than ten degrees below zero, so that many people suffered from hypothermia, and even more directly It''s freezing to death. "


    With that, Chen Xin gave a detailed introduction to the two sisters of the Mo family about the situation in the urban area and why he stayed so long in the urban area.


    "I didn''t expect you to do so many things in the city. It''s hard for you." Knowing Chen Xin''s busy time, Mo Qingyan''s attitude towards him softened a lot, and she was even more moved. He even remembered to visit his home: "let''s do that for the time being in my house. It''s very troublesome for those wines to thaw. Moreover, the taste will have an impact after thawing. It''s better to keep them, and I''ll deal with them later."Although she is very distressed about her collection, Mo Qingyan can''t go back to deal with the wine now. Moreover, her family is frozen under the snow. She and her sister alone have no ability and method to clean it up.


    So she didn''t get tangled. She planned to put it like this first. She planned to wait for a period of time and try to deal with it when she went back.


    "Well, since you say so, we''ll talk about it then. When Alan and I came out, we locked the door again. No one will go in. You can rest assured about that. " Chen Xin''s attitude towards Mo Qingyan is natural.


    Having said all these things, Mo Qingyan sees Chen Xin''s face is a little tired, so she holds her sister who wants to say something else and says to Chen Xin, "ah Xin, go to have a rest first. You must be tired when you come back from the city. Have a good rest first, and talk about something later."


    "Well, I''m really a little tired. I''ll take a bath first. I haven''t taken a good bath in the city for so many days, but it''s suffocating me." With that, Chen Xinchong, Mo Qingyan and Mo Qingxin smile for a while. Then they go to their room upstairs and plan to take a good bath to relax themselves.

 Chapter 319

    Chen Xin, who returned to his home, threw himself into the bathroom, and the whole person was comfortable in the warm bath.


    This room is designed as a bathroom, in addition to a large bath and two shower heads that occupy 80% of the bathroom area, there are no other facilities that can make people fully enjoy the fun and comfort of bathing.


    The water in the bath is hot spring water from the underground. Although the extremely cold weather has also affected the water temperature, it is still a very comfortable thing to soak in with the help of auxiliary heating.


    Although each room in the shelter has its own shower facilities, bathing and bathing are obviously two different things. One is just to clean the body, the other is to relax the body and mind.


    Before the disaster, this may be a very common thing. Most ordinary people can enjoy it if they want to.


    But now, after the disaster, it''s a real luxury. Without enough resources, it''s hard to enjoy bathing.


    Before, in the urban area, although the refuges had better heating capacity and sufficient hot water supply after Chen Xin improved the boiler, what they could provide to the survivors was only hot shower, not bath.


    Although bath from the direction of treatment, for hypothermia and frostbite has a very good therapeutic effect, but let people take a bath and let people take a shower, the consumption of the two is completely different.


    After all, in order to save water resources and coal, although the official refuge has opened the shower, so that survivors can take a hot bath, there is a time limit. Although 15 minutes is enough time to take a comfortable bath, there is absolutely no enjoyment.


    Thinking of this, Chen xinpao couldn''t help thinking about whether he wanted Li Yulong to set up a bathroom in his refuge in the city. Many people would like to take a bath, right?


    However, this idea is to give up after hovering in his mind. It doesn''t mean that he can''t do it. On the contrary, it''s too simple for him to do it specially. As long as he talks with Li Yulong, he can deal with it well.


    Today''s Chen Xin is more concerned about how to help the country''s post disaster reconstruction and how to improve the living standards of the survivors. He has no energy to think about such small things.


    This is not a superhero plot in which Chen Xin sets himself too high, nor is it a superhero plot in which the more capable he is, the more responsible he is. It''s just a very simple story. If he is poor, he will be alone, and if he is successful, he will help the world at the same time.


    It is not difficult to understand or impossible to take good care of yourself and your family when you are not able to do your best to help others when you are able to.


    Although it is more difficult to survive in the end of the world, everyone is already struggling to live on their own and has no spare energy to help others. Some people even become selfish and will seize the opportunity for others to live in order to survive.


    But for Chen Xin, he has been able to live a good life, can also live a better life, and help others live a better life at the same time, there is no problem.


    Because he has the ability, and to do so, there is no loss for him.


    Now he has given the drawings of the national exoskeleton protective clothing, which can enable most people to regain the ability of outdoor activities. The country is also organizing the production; the production line of isotope thermoelectric battery has been built and will be put into use soon; the construction of the improved communication base station has been started before the blizzard, and the laying of the communication network is only a matter of time There are


    In fact, Chen Xin has done a lot of things and helped a lot of people.


    For example, if there were no help from the 200000 survivors in the urban area, a considerable number of them would have died in the blizzard. For Chen Xin, saving so many lives is a matter of great achievement.


    In addition, for Chen Xin, it is also very attractive if he can let the country complete the post disaster reconstruction, let everything return to normal, and let his life return to what it was before the disaster.


    So he is now considering how to continue to improve the living conditions of the urban area and speed up the post disaster reconstruction.


    The Dome City mentioned in the previous discussion with scientific researchers is certainly a very suitable choice, but the construction of the dome city is too difficult and impractical.


    In addition, there are other ways to improve the living conditions of cities.


    In the current environment, the biggest problem and challenge for survivors is cold. If the temperature can be raised, many problems can be solved.


    And when it comes to heating up, the energy tower that can still guarantee urban heating in the low temperature of more than 100 degrees below zero, which is also in the cold environment construction game "ice age", is obviously a good choice.


    Although it''s the black technology in science fiction, the energy tower itself is only based on the product of the steam age. It''s not impossible to recreate it in reality.


    It''s just that even if it''s reproduced, it''s impossible for the energy tower to be able to heat a city, because it''s a big boiler. It''s better to use steam or hot water to heat a city simply by using a boiler.In this way, not only the heating efficiency is higher, but also the heating effect is much better. After all, except for Chen Xin, who wants to raise the temperature of a whole area, no one will consider the radiant heating method of energy tower, which is too low in efficiency.


    Unless it''s not just burning coal to generate heat, it''s using coal to drive the machine and get more heat from other sources.


    This is really feasible. For example, the ground source heat pump Chen Xin now uses in his refuge is such a product. It relies on electricity to drive compressors and pumps to get more heat from the ground.


    Thinking of this, Chen Xin can''t help thinking of the setting that in order to build the energy tower in the game, we must first dig a deep foundation. He conceived in his mind and thought that this is a very feasible plan.


    First, dig a deep enough pit to reach the deep stratum, and blow air into the pit to form air flow, so as to bring the geothermal energy in the deep stratum to the surface, and then use it to raise the temperature. In this way, a small amount of energy consumption can be used to obtain a large amount of heat energy.


    And with enough heat, whether it''s for heating or generating electricity, it''s enough to change the status quo of a city.


    With this in mind, Chen Xin gradually formed a construction plan with the energy tower as the core.

 Chapter 320

    Chen Xin plans to build an energy tower, and then use the energy tower as the core to heat and power a city.


    If there is no system, this is only a beautiful idea. Although it can be realized technically and theoretically, in fact, it is impossible to build such an energy tower.


    First of all, it is a very large amount of construction to dig a deep pit underground enough to reach the deep stratum. Although a deep well of several thousand meters can be drilled with modern drilling technology, that kind of deep well does not have the value of being used as the foundation of energy tower.


    Take the Kela deep well excavated by Lucia, the most boasted online, as an example. On the Internet, many people boasted that she had dug directly into the deep well of hell, from which many monsters had flown, known as "the gate of hell". Even in those years, former sovya intended to dig through the blue star


    However, if you really look up the data, you will find that the so-called "gate of hell" well is 12262 meters deep, with a diameter of 92cm in the upper part and 21.5cm in the lower part. In terms of its diameter, it''s hard for people to go down.


    In fact, the so-called deep wells on the earth are not giant tunnels as you imagine, but small holes with only one drill bit and drill pipe, even oil drilling.


    The deepest mine in the world is more than 4000 meters deep, but that is the result of continuous downward excavation in more than 100 years. It is not a deep well directly to the bottom, but several excavation planes. The so-called 4000 meters deep part is the deepest bottom of the whole mine .


    Here, the environment is extremely harsh, the temperature can reach 57 ¡æ, which is beyond the limit that the human body can tolerate.


    Of course, it also proves the feasibility of drilling deep wells into deep strata to utilize geothermal energy.


    According to Chen Xin''s idea, the structure of the energy tower should be to drill two wells more than 3000 meters deep underground and make the bottom of the tower run through. One well is responsible for blowing air downward and the other is responsible for pumping air upward to extract deep geothermal energy through air.


    The surface part is actually equivalent to a huge blower and heat energy converter, which is used to blow air into the deep well to extract geothermal energy, convert the extracted heat energy into electric energy, or directly transport the heat energy to the place where it is needed.


    Moreover, Chen Xin does not intend to adopt such a bold and unconstrained way of directly discharging into the air. Instead, he plans to use the existing underground transportation network to lay heating pipes and transfer heat energy to all parts of the city.


    In this way, the overall temperature of the city can be improved. In addition, the refuges are not very deep underground. After the temperature rises, the excess heat energy is emitted to the surface through the bottom layer, which can indirectly improve the surface temperature.


    Of course, if you really need to create a heating field on the surface, you can also use pipes to connect a radiator on the surface, so as to create a heating area.


    This is similar to the radiator or stove in the game. You can create a small heating field artificially. Although the heating efficiency may not be good due to the environmental impact, it is also of great practical significance to raise the temperature from - 50 ¡æ to - 30 ¡æ!


    Whether it is ground construction, or the establishment of surface greenhouse, or other purposes, it has a high practical value.


    What''s more, with Chen Xin''s improvement, the small heating field made of this kind of radiator can''t only raise the temperature by 20 degrees.


    If this idea can be realized, as long as the efficiency of the energy tower and radiator is enough, then human beings can really return to the surface to live.


    In the future, even though the surface temperature is still very low, after the return of sunlight, there will be an energy tower and radiator to let human beings return to the surface, rather than a refuge under the ground. This will have a completely different significance for human civilization.


    However, it is not difficult to realize the radiator that can build a small heating field, but the energy tower that can provide heat for a city is not so easy to realize.


    This involves engineering, thermodynamics, materials science, building mechanics and so on It''s not up to one person.


    Even if Chen Xin can use the system upgrade method to save many steps, if it can''t be copied in other places and can only rely on Chen Xin''s system upgrade to build the energy tower, the practical significance of this thing is still small.


    After all, Chen Xin is alone. He needs to spend a lot of survival points to build such an energy tower. If he wants to build such an energy tower in all or most cities of Yanguo, it will take too many survival points and time for Chen Xin. Even whether he can do such a thing in his lifetime is still unclear.


    Therefore, the best way is the same as before. He builds a finished energy tower, and then gives it to the state to send people to reverse crack it. In this way, we can realize the idea of letting human beings return from the underground to the ground without relying on Chen Xin to copy it in other places. Only with the support of the state can we erect energy towers in most cities in China.


    However, it is obviously very troublesome and complicated to build an energy tower. After all, Chen Xin''s ability is only upgraded, not created out of nothing. He must have a foundation that can be regarded as an energy tower to upgrade it into a real energy tower.This is the usage rule of the system. Even if he just makes an iron shelf to burn coal inside, he must weld an iron shelf first.


    Therefore, this matter can not be solved or made effective in a short time. Chen Xin decided not to think about it for the time being. This kind of long-term investment can only be effective without rushing to start. It''s more practical to first look at what can be done in the near future.


    "The battery production line has almost been installed now. If you go back and upgrade it, you should be able to use it." Chen Xin is lying in the bath, counting what he has done or is doing. At the same time, he is planning what he plans to do: "when the battery production line starts to run, we can consider building a generator production line, so that we can have enough energy. The rest is to build a large-scale greenhouse and energy tower on the ground. Maybe these two things can be done together... "


    Chen Xin thought of his previous plan to build a large-scale greenhouse on the ground, and felt that it could be connected with the plan of the energy tower. After all, the main function of the energy tower is heating, and planting a greenhouse just needs large-scale heating.

 Chapter 321

    After a night''s rest in his room, Chen Xin got up the next day and finished his breakfast. Then he took the elevator to the upper floor again. However, instead of coming up alone, he came up with his parents and Mo''s sisters.


    Not only that, everyone, including Chen Xin, is also wearing an exoskeleton protective suit and holding a shovel and other tools made by Chen Xin.


    They are going to sweep the snow.


    When Chen Xin came back yesterday, Han Ping just dug a way out of the shelter so that Chen Xin could come in. The whole gate of the shelter was still covered with snow. If you want to go out, you must clear the snow at the gate.


    Cleaning up the snow that can cover the whole person is obviously not something that one or two people can do. Chen Xin naturally mobilized the labor force in the shelter.


    Originally, Chen Xin only planned to call Mo Qingyan and Mo Qingxin, but his parents thought they could do it, so they came with him.


    A group of people to the surface, Han Ping has also put on protective clothing, waiting in front of the gate.


    Han Ze didn''t come along, but was sent by Chen Xin to keep on guard to prevent them from coming when they were working.


    After all, when clearing snow, the gate of the shelter is open. At this time, if someone wants to raid the shelter, it is very dangerous that no one stands guard.


    However, Chen Xin did this just in case. In the current situation outside, it''s difficult to walk or drive. Before, he was able to walk all the way back from the city with power armor. He doesn''t think other people have such ability, but there should be some safety measures.


    "Han Ping, please help my parents. They are old. Take care of them." Chen Xin gave the tools to the crowd, and whispered to him when he handed Han Ping the shovel.


    Han Ping nodded clearly and took the initiative to go to Chen Xin''s parents to help them with their tools.


    However, Chen Xin''s parents refused Han Ping''s help. Seeing this, Han Ping had to stay with them and planned to do more later so that Chen Xin''s parents would not have to work too hard.


    After all, among so many people, only Chen Xin''s parents are the elderly. They are not as strong as the young people. They should do more.


    Chen Xin took the lead in climbing out along the passage Han Ping dug yesterday. Instead of directly shoveling snow, he estimated the position above the gate according to the position he climbed out. He planned to clean up the snow outside the observation room and at least expose the observation window.


    is a place to live in, but Chen Xin is familiar with her home. Chen Xin uses the gate as a reference. Chen Xin soon found the approximate location of the observation room, shovel the snow with her spade, and set a foothold for herself. After that, Chen Xinbian dug up with the help of the exoskeleton.


    The reason why he didn''t wear power armor today is that the weight of power armor is a little heavy. If he was wearing that suit, even if Chen Xin patted all the snow under his feet, it would be very difficult for him to stand up. If the whole person was trapped in the snow, he would not be able to move unless he was forced to squeeze in the snow by the power of power armor as before State.


    So relatively speaking, more lightweight and flexible exoskeleton protective clothing has become a more suitable choice than power armor.


    Relatively speaking, power armor is more suitable as a kind of combat equipment. If it is used for daily work and going out, Chen Xin still feels that exoskeleton protective clothing is more comfortable to wear after using it for a period of time.


    with the help of the exoskeleton, Chen Xin quickly excavated a large amount of snow with a spade. He pushed the snow aside, and dug as much as possible to the target, and soon he dug up the hard stuff and struck it with the spade, shaking Chen Xin''s hands.


    cleared the snow. Chen Xinwa arrived at the wall of the observation room. The shovel just touched the wall.


    Now that the wall has been dug, the rest is much simpler. Chen Xin quickly cleans up along the wall, digs out the observation room which is deeply buried in snow, cleans up the snow in front of the observation room, and reveals the observation window under the snow.


    However, there is obviously some ice on the observation window. Chen Xin still needs to break the ice, and he should be careful not to break the glass together.


    He knocks off the ice on the observation window and greets Han Ze inside. Chen Xin turns his head and continues to clean up along the observation room. He does not forget that the vent of his refuge is installed next to the observation room.


    Because of the relationship between the greenhouse and the oxygen generator, whether the air vent can be changed or not has little impact, but if the air vent is buried, there will still be some inconvenience, so we still need to take advantage of the opportunity to clean out the air vent.


    The process of cleaning the vent is very easy. Although there is ice near the vent, it doesn''t take much effort.


    By the time Chen Xin finished clearing the snow at the vent and went down the way he had come up, Han Ping and the Mo sisters had cleared a large area at the gate of the shelter.


    "It''s very sharp, long Niang!" Chen Xinchong says hello to Mo Qingyan."You''re not slow, either. All the snow on it has been shoveled away?" Today''s Mo Qingyan seems to be in a good mood, not as cold as before to Chen Xin.


    "Well, it''s all cleaned up. The observation window and vent are a little frozen, but it didn''t take much effort." Chen Xin explained to Mo Qingyan the situation above, and waved the shovel to clean up the snow at the gate with her.


    The snow brought by the previous snowstorm has accumulated more than four meters deep at the gate of Chen Xin''s shelter. Although this is only the part close to the gate, the deeper the snow is, the shallower the snow is, it is not an easy job to shovel all the snow.


    Even with the help of exoskeleton, it doesn''t take much effort to dig out a large area of snow, but it''s a huge project to dig out the snow with an average depth of more than two meters and an area of at least one or two hundred square meters in front of the door.


    Fortunately, including Chen Xin, a total of six people are wearing exoskeletons. Even if Chen Xin''s parents are older and less able to work, the efficiency of cleaning up is still not low.


    From the morning to lunch time, a large piece of snow has been cleared out of the gate, revealing the gate which was buried by snow and a small open space at the gate.


    "Well, let''s finish here in the morning, have a lunch break, and do the rest in the afternoon." Chen Xin took the initiative to ask the Mo sisters and their parents to have a rest.


    Just as Chen Xin said this, Han Ze''s voice came from his communicator: "Mr. Chen, there is a light in the distance!"


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 322

    Hearing Han Ze say that there is a light in the distance, Chen Xin is surprised and puzzled. The snowstorm has just passed. How can someone come here?


    However, it didn''t affect Chen Xin''s response. He asked his parents and Mo''s sisters to return to the shelter. He also took Han Ping to close the door of the shelter. Chen Xin then came to the observation room, took the telescope from Han Ze and looked into the distance.


    Sure enough, as Han Ze said, in the snow in the distance, there are several lights coming towards the direction where Chen Xinjia is.


    "So fast! What is this? " Chen Xin estimated the speed of light approaching, but found that the speed of that thing was very fast, obviously not like a car.


    Because of the snow, the car can''t move quickly on the snow, and the light obviously looks like a vehicle with only one light, not like a car should have two lights.


    Just when Chen Xin was confused, the vehicles represented by these lights also approached Chen Xin''s shelter, stopped in front of the empty space just cleared by Chen Xin and others, and sent a communication.


    "Comrade Chen, it''s me, old li of SWAT team! Please open the door Li Tou''s voice came from the radio. Chen Xin was relieved and asked Han Ping to open the door.


    And he himself in the observation room with binoculars and carefully looked at two eyes, this is from the observation room down to the door.


    When the door opened, Li Tou and others rushed down from the vehicle and separated two people to look at the vehicle. At the same time, the others quickly entered Chen Xin''s refuge.


    After the gate was opened, Chen Xin finally saw clearly that the vehicle Li Tou and others were riding was a snow motorcycle by the light inside the gate.


    This kind of vehicle was originally used for snow, but now it is very practical. In particular, there is a crawler with a body in the snow motorcycle ride by Li Tou and others. It looks like it is used to tow goods, which makes Chen Xin even more conspicuous.


    "Snowmobiles? You''re freezing to death on such a cold day! " Chen Xin looked at the ice shell on Li Tou and others who walked into the shelter, and the snowflakes on their eyebrows. He couldn''t help laughing.


    "No! But I can''t help it. If I can''t drive now, I can only ride this one. " Li Tou shook the snowflakes and ice cream on his body. Then he replied to Chen Xin with a bitter smile: "Comrade Chen, what are you wearing? It looks good! "


    "Exoskeleton protective clothing, the state has a production plan, there should be the first batch of exoskeleton protective clothing in the near future. It depends on whether you can get it." Chen Xin shrugged his shoulders and brought the topic back to business: "you people in cold weather don''t do post disaster reconstruction in the urban area. What are you doing here? To pick up the vegetables you left here last month? Don''t worry, it''s all frozen in the warehouse for you. If you want to take it away, it will be confiscated this month. If you want, you''ll have to wait for tomorrow. "


    "Thank you very much Li Tou was overjoyed to hear Chen Xin say so.


    They did come to get vegetables, but they didn''t give much hope when they didn''t come. After all, after a snowstorm, no one expected vegetables to be preserved for a month.


    However, Chen Xin put the vegetables in the warehouse before and made them survive for a month by freezing them at low temperature. Although they may be damaged by freezing, they can still be eaten at least.


    Knowing that last month''s vegetables were still there, Li Tou was relieved and turned to explain to Chen Xin why they came here: "the material supply in the urban area is a little tight now. Although there is enough grain in reserve, it has been almost a year since the meteorite fell down. Almost half of the grain in the shelters has been eaten, and vegetables and fruits have been gone for a long time A large number of bread worms and mice raised in the past have been frozen to death this time. The city government is having a headache about this! "


    Although Li Tou said it was not serious, the information he revealed still made Chen Xin feel the seriousness of it.


    "Isn''t the city government engaged in underground planting? I used to see it when I helped them rebuild their boilers. Don''t they have vegetables and fruits there? And fish and poultry. And what about the mushrooms in the shelters? " Chen Xin frowned and asked Li Tou. Although he expected that the cold brought by the snowstorm would affect the food problem, he didn''t think it would be so serious.


    Li Tou shook his head with a sigh and explained to Chen Xin: "although there is still a lot of output in the underground planting area, compared with the consumption of more than 200000 survivors in the whole urban area, it is just a drop in the bucket! Moreover, this snowstorm has also seriously affected the underground planting area, and many crops have been seriously reduced even if they did not freeze to death.


    Although the mushrooms in each shelter have a certain output, they can only partially supplement the food consumption. The previous snowstorm destroyed most of the mushroom houses, and everything has to be done again. It is difficult to resume production in a short time.


    In addition, the municipal government used emergency reserves before, and now the material supply in the urban area is really a little tight. Now we are considering limiting the supply. "


    When Chen Xin heard what Li Tou said, he realized the seriousness of the problem.


    But in the face of this problem, he has no good way.


    He can upgrade the greenhouse, increase the planting area of crops, so that people can plant more crops, but it takes time for crops to grow. Even if high-yield seeds and chemical fertilizers can push up the yield, it can''t go against the law of nature, so that the seeds can be planted today and grow tomorrow.As for his own output, although it''s more than enough for him to eat, he can also give some support to others. However, if we want to solve the food crisis, we can''t rely on Chen Xin to solve this problem unless he regenerates his greenhouse several levels and turns it into a large-scale planting factory.


    If we really want to solve this problem, we have to rely on the state.


    But although the country''s material reserves are large, a large number of materials have been stored before the disaster, but after more than a year of consumption, how much can be left is a worrying problem.


    After all, this is not to say that today''s food supply will be over. No matter how much food reserves are used up, we must consider how to supply so many people''s rations after the food reserves are used up.


    Although Yanguo has the largest population after the disaster, which provides a large number of post disaster reconstruction labor and technical personnel for Yanguo, it is also a heavy burden, which forms a huge test for Yanguo''s logistics support capacity and material production capacity.


    However, for Chen xinlai, this kind of thing is neither involved nor concerned by him. Instead of worrying about whether the country has enough food to eat, it''s better to consider the large-scale cultivation of greenhouse in his plan. If it can be successful, it can not only open up food producing areas, but also provide technology accumulation for the future energy tower plan. It can be said that it can achieve more with one stone .

 Chapter 323

    He took the vegetables that had been frozen in the warehouse to Li Tou and watched them put boxes of vegetables on the snowmobiles. Chen xinyuefa felt that he could get some of these snowmobiles.


    So he asked Li Tou, "where did you get these snowmobiles from? If I want to exchange, will you exchange it? "


    "This is provided by the Municipal Bureau. It can''t be changed, can it?" Li Tou doesn''t know how to answer this question. These are police equipment. Obviously, they can''t be traded according to the management regulations. But in this world, no one can say what to do with some things.


    What''s more, with Chen Xin''s current cooperation with other countries, it''s very easy for him to get two snowmobiles.


    Thinking of this, Li Tou said to Chen Xin, "Comrade Chen, don''t you have a good relationship with the scientific research institutions over there? If you want to get two snowmobiles, it should be easy to get them, right? The snowmobiles in our SWAT team are also distributed from the top. It may be easier for you to find them directly. "


    Hearing Li Tou say so, Chen Xin also gave up the idea of exchanging snowmobiles through the special police team.


    If there is no cooperation with the state''s scientific research institutions, Chen Xin may really have to find a way through the SWAT team, but now that he has reached cooperation with the state, it is not difficult to get two snowmobiles.


    Chen Xin gave up the idea of exchanging snow motorcycles through the SWAT team, but this month''s vegetable output will be exchanged.


    However, with the increasing output of Chen Xin, the materials he needed to exchange gradually changed from food to daily necessities.


    Although Chen Xin does not worry about food and drink, all kinds of vegetables and staple food have begun to be produced, and even can be eaten in a different way. With the growth of chickens, Dalian meat will also get a stable supply, but when it comes to daily necessities, most of them cannot be made by themselves.


    The most intuitive thing is toilet paper, which can be said to be used every day, but basically can''t be self-made.


    There are soap, shampoo and so on. It seems homely, but in fact, few people will consider self-made things, which are also unlikely to be self-made.


    At present, Chen Xin can only obtain these things by exchanging materials with others. Although it is not limited to the SWAT team, Chen Xin can also obtain living materials directly through scientific research institutions. However, Chen Xin does not intend to do so, but continues to maintain the trading channel with the SWAT team.


    Even if it''s not for the exchange of materials, it''s necessary to maintain the relationship with the SWAT team.


    After seeing off Li Tou and others, Chen Xin returns to the lower level of the refuge.


    His mother is cooking lunch, while Mo Qingyan is helping.


    Chen Xin goes to the kitchen door and talks to Mo Qingyan about what happened just now. He tells her, "long Niang, don''t shovel snow in the afternoon. Let''s collect the vegetables in the greenhouse with Xin Xiaomei."


    "It''s enough for me to collect vegetables alone. Xiaoxin, I''d better help you." Mo Qingyan doesn''t plan to ask her sister to help.


    Chen Xin''s greenhouse is fully automated. Although harvesting by one person may be a bit tiring, it doesn''t mean that two people are required.


    And Mo Qingyan, who has been shoveling snow for a whole morning, knows how much work there is. One less person may be able to finish today, but two less people will have to put things off until tomorrow.


    Hearing Mo Qingyan say so, Chen Xin didn''t object, but nodded his head to agree.


    "By the way, I saw you have a dryer before, and I wanted to tell you at that time, but when you go downtown, you forget about the food." Mo Qingyan stopped her work, went to Chen Xin and said, "I think you can use the dryer to make dehydrated vegetables, which can reduce the storage space and prolong the storage time of vegetables.


    You have fresh vegetables every day. You don''t need them, but you can sell them to Bruce Lee. I think it''s more practical for him to sell dehydrated vegetables than strawberry jam. "


    "Dehydrated vegetables? This can be done, but is my dryer efficient? " When Chen Xin heard Mo Qingyan say this, he first thought about whether the dryer was enough.


    After all, it will be a big project if we want to rely on the dryer that can only dry dozens of kilos of vegetables at a time.


    However, Chen Xin was still talking to Mo Qingyan about this, while Chen Xin''s mother suddenly said, "what kind of dryer do you want? You wash the vegetables and dry them, then put them on the heat pipe of the ground source heat pump and dry them in one day.


    When you were a child, I used to dry pickles in the water pump room, but at that time, it was the heat emitted by the motor, not the heat directly put on the pipe. "


    Hearing what his mother said, Chen Xin also patted his head and felt that he really lacked life experience.


    Their generation has been used to buying all kinds of things online, relying on machines or various auxiliary tools to achieve their goals, but like Chen Xin''s parents, their generation are more used to solving problems by what they have on hand.Like dehydrated vegetables, Chen Xin and Mo Qingyan think of dryers, but Chen Xin''s mother thinks of sun drying first, followed by drying, and drying can be done as long as there is a heat source, not limited to having a sufficiently large dryer.


    When Chen Xin was a child, his family wanted pickled vegetables or something in winter. Without the sun to dry them, they would put the washed and dried vegetables on the radiator and dry them with the heater.


    Compared with using the dryer, it is not only less labor-saving, but also does not need additional costs.


    Chen Xin also reacted, so he said to Mo Qingyan: "in this case, long Niang, you should take all the vegetables first, and you should divide the parts for the special police team and put them in the warehouse above. We can eat the rest by ourselves, and the rest will be dried in the machine room to make dehydrated vegetables."


    "OK, but in this case, I can''t deal with so many vegetables alone. I''ll go back to..." Mo Qingyan hesitated for a moment, and then said to Chen Xin, "come back and help. Aren''t you an intermediate chef?"


    Hearing Mo Qingyan say so, Chen Xin smiles, but still nods: "OK, you take the vegetables today, I''ll deal with them for you tomorrow."


    With that, Chen Xin walked into the kitchen, came to his mother and asked if he could help.


    Mo Qingyan watched Chen Xin roll up her sleeves to help cook. After a pause, she went over and continued her work and helped to cook lunch together.

 Chapter 324

    At present, the total amount of vegetables that can be harvested in one month in Chen Xin''s greenhouse has exceeded 2000 Jin.


    In addition to cabbage and lettuce, there are carrots, cucumbers and tomatoes, as well as pepper, which is indispensable for people in Hunan Province.


    Mo Qingyan planted cucumber, tomato and pepper last month, but they have not yet borne fruit. If all these crops bear fruit, Chen Xin''s total vegetable production will go up to a higher level.


    So far, Chen Xin has planted two layers of upland rice, one layer of cabbage, one layer of lettuce and one layer of pepper, one half layer of carrot, one fourth layer of yellow flower and one fourth layer of tomato.


    Cabbage and lettuce can be harvested once a month, which is the main vegetable output of Chen Xin. Every month, they are used to exchange living materials with the SWAT team.


    As for carrots, peppers, cucumbers and tomatoes, they are collected only once every few months. Although most of them are also exchanged by Chen Xin for goods, most of them are stored and eaten by themselves.


    In addition, some other vegetables and fruits were planted sporadically in the corner of the greenhouse, as well as the herbal medicine that Chen Xin promised to grow for Hongrui. However, it only occupied a small area in the greenhouse, and the yield was almost negligible. That is to say, it was enough for the people in the shelter to taste and change their taste.


    But even so, the total output of more than 2000 Jin of vegetables per month, even though Chen Xin and the special police team have expanded the total amount of transactions, and exchanged the largest part of each month''s output for living materials, the rest is still a big weight.


    Although several hundred jin of vegetables can be thrown into the warehouse and stored directly at low temperature, Chen Xin''s warehouse still needs to hold other things, and can''t put down many vegetables. Once rice and carrots can be harvested, the warehouse is bound to burst.


    So it is necessary to make fresh vegetables into dehydrated vegetables.


    Dehydrated vegetables are not traditional dry vegetables. There are great differences in processing methods and nutritional value between them.


    Traditional dried vegetables are dried in the sun for a long time to remove moisture. Because the drying time is too long, the vegetables not only lose color and moisture, but also lose a lot of nutrients, and the organizational structure is damaged. Even if they are soaked in water, they will not recover, and the taste will be very poor.


    So usually, sun dried vegetables are not eaten directly, but used for pickling, making secondary processing products such as pickles, pickles or pickles, which are easy to store and improve the flavor.


    If you eat it at ordinary times, these pickled dried vegetables are of course refreshing dishes. It''s a good choice to enrich the dishes, seasoning and remove the greasy.


    But if it is in the case of food shortage, long-term consumption of pickles will undoubtedly cause malnutrition and many other physical problems, in this cold environment, it is very unhealthy.


    Dehydrated vegetables are not the same, because they are dehydrated in a short time by artificial means, and both nutrition and taste can be retained to a great extent. As long as they are put into water, they can restore their original appearance. It is not only convenient for storage, but also convenient for eating. It is a very good way to store vegetables in the last days.


    It''s not difficult to make dehydrated vegetables. Chen Xin helped Mo Qingyan put the part of the harvested vegetable seeds that needed to be handed over to the special police team into the warehouse, and then began the preparation of dehydrated vegetables.


    "Ingredients, are you going to cut these vegetables?" Mo Qingyan looks at Chen Xin moving fresh vegetables to the kitchen and asks him curiously.


    Chen Xin nodded and took the vegetables out of the plastic box and put them into the sink. While turning on the tap to wash them, he replied to Mo Qingyan, "cut them into strips to keep them. If you want to keep the whole plant, it''s not easy to drain and dry them."


    "I''ll help you. How can I cut it?" Hear Chen Xin say so, Mo Qingyan very active want to help.


    "Why don''t you just cut it into strips?" Chen Xin looked up at Mo Qingyan strangely and asked, "I remember long Niang, you should have done this? Why don''t you seem to be able to do it? "


    As a field survival enthusiast, Mo Qingyan will certainly make emergency reserves for dehydrated vegetables, but she doesn''t look like she will.


    In the face of Chen Xin''s question, Mo Qingyan just said slightly: "I''m not worried that your practice is different from what I know! You''re an intermediate chef. Who knows if you want a flavor or something? "


    "Er..." Facing Mo Qingyan''s obvious arrogance, Chen Xin could only touch his eyebrows and said, "it''s just dehydrated vegetables, not dried fruits and vegetables. Why should I make seasoning. But you remind me that next month, you can adjust it, plant less cabbage and lettuce, plant sweet potato and other crops, and then you can make some dried fruits and vegetables to eat. "


    ¡°¡­¡­ Well, whatever you like. " Mo Qingyan looks at Chen Xin and hears him say so. It''s hard to say more.


    Chen Xin saw that Mo Qingyan didn''t say anything more, so he turned his attention back to the treatment of vegetables in front of him. He washed some vegetables in the pool and broke them into pieces before he said to Mo Qingyan, "these vegetables I washed are cut into shredded vegetables. The chopping board and kitchen knife are there. Be careful not to cut your hands.""I see. Do I look like someone who can cut his hands when cutting vegetables?" Mo Qingyan replies to Chen Xin, then goes to the kitchen table, takes the chopping board and kitchen knife, puts Chen Xin''s dishes on the chopping board and cuts them.


    While cutting vegetables, Mo Qingyan suddenly asks Chen Xin, "are you and a LAN going to get back together?"


    "Well, why do you ask that?" Chen Xin was a little surprised. The question Mo Qingyan asked was obviously unexpected.


    "Well? Isn''t it? You both sleep in the same bed. If you don''t want to be with Alain, you''re a scum man. " Mo Qingyan''s attitude is very direct and her words are very straightforward.


    "Well Let''s see what ah LAN means. You know the original situation. I can''t say whether she wants to be with me or not. " Chen Xin''s answer is somewhat evasive.


    This answer obviously can''t satisfy Mo Qingyan. She yells at Chen Xin with some dissatisfaction: "what do you mean? Ah LAN is sleeping in the same bed with you. Would you like to see her? What do you want from a girl that you think she''d like to be with you? Ah LAN has to say "we are together" to you, right


    "Well OK, OK, I know. I''ll talk about it with Alain. " Chen Xin nodded awkwardly. However, when he continued to wash vegetables, he muttered in a low voice: "what do you mean when you live in my house like this?"

 Chapter 325

    Mo Qingyan''s questioning of Chen Xin can only be regarded as a small interlude, because Qin LAN is not in the refuge. Although Chen Xin feels embarrassed, it does not cause any impact or change.


    Chen Xin washed several hundred jin of fresh vegetables and gave them to Mo Qingyan to chop. After that, he took them to the machine room and spread them out on the shelf made yesterday.


    These shelves are very simple. They are just a few steel pipes welded together and covered with layers of gauze. This is what Chen Xin did last night for the convenience of drying vegetables today.


    Put the cut vegetable silk on the gauze net and spread it to facilitate water evaporation. Chen Xin put these shelves on the heating pipe of the ground source heat pump.


    "Is that all right? Will it not dry? " Mo Qingyan saw that Chen Xin just put the shelf on the water pipe instead of putting the cut vegetables on the water pipe as Chen Xin''s mother said. She couldn''t help worrying about whether it would not dry.


    Chen Xin shook his head and explained to Mo Qingyan, "of course, it''s OK to put it on the tube, but the utilization rate is a little low and it''s not conducive to the evaporation of water vapor. Plus, the amount is a little large, so it will be better."


    Hearing Chen Xin say so, Mo Qingyan didn''t say much, just asked: "is the temperature enough? I remember that dehydrated vegetables used to be dried at 80 ¡æ in the oven. Even if you put them on the heating pipe, the temperature may not be enough, right


    "The temperature of the heating pipe exceeds 80 ¡æ, and the temperature of the air above is close to 60 ¡æ. It''s no problem to dry vegetables." Chen Xin of course considered this problem, and did not worry about it: "and generally, the temperature of about 60 ¡æ is enough for drying vegetables and fruits. In addition, it is open, and the water vapor evaporates quickly, so it will not dry."


    Although Chen Xin said so, Mo Qingyan still felt uneasy and touched the heating pipe. She really felt some hot hands. The air above the pipe was also hot, so she nodded at ease.


    Although Chen Xin''s shelves are multi-layered, several shelves can''t hold hundreds of kilograms of vegetables. Especially in order to ensure adequate ventilation, Chen Xin can''t put too many vegetables on the gauze net, so after all the shelves are full, more than half of the vegetables are not put on.


    Seeing this, Chen Xin could only say to Mo Qingyan, "it seems that we can only dry them in batches. This batch should be dried here first, and the rest should be put on when this batch is almost dry."


    "Will you put the rest away?" Mo Qingyan looks at the rest of the vegetables and is worried that it will be bad if they are put like this.


    Chen Xin thought about it and said, "let''s put it here, spread it out a little, and turn it every few hours to avoid water accumulation. One day''s work will not be bad."


    "All right, as you say." Mo Qingyan nodded and together with Chen Xin piled the remaining vegetables in the corner of the machine room.


    After leaving the machine room, Mo Qingyan was about to go to the greenhouse, but she suddenly stopped and asked Chen Xin, "by the way, the sweet potatoes you brought back before are going to be planted after this season''s rice harvest? You said cabbage and lettuce should reduce the planting area, so what do you plan to plant next? "


    "Well..." Asked this question by Mo Qingyan, Chen Xin pondered for a while, considered it for a while, and then asked Mo Qingyan, "can the sweet potato I brought back last time be planted?"


    "That''s OK. After you get it back, I''ll do the seedling raising, which can be planted in a month." Mo Qingyan nodded, indicating that these sweet potato seedlings had been planted for a long time.


    Chen Xin made up her mind when she heard that, so she said, "since the lettuce and cabbage have been collected, only a quarter of them will be planted this time. Let''s spare one layer for sweet potato. As for the remaining half layer, you can see what kind of vegetables or fruits you want to eat. Just plant a few more varieties, and the output will be enough for us to eat. "


    "Is that so? That''s fine. I''ll plant whatever I want Mo did not object to Chen Xin''s decision, but confirmed to him, "do you want more leafy vegetables or more melons and fruits?"


    "There are many kinds of leafy vegetables. I remember the seeds of green onion, garlic and coriander, which can also be used as seasoning when cooking." Chen Xin remembered that he hadn''t eaten onion, garlic and coriander in his meals for almost a year, so he couldn''t help being greedy.


    For Chen Xin''s proposal, Mo Qingyan also readily accepted, nodded her head seriously and said: "these things need to be planted, otherwise, the food will not smell good! And the fish in the pool under the greenhouse has been raised for such a long time, so it''s time to eat. "


    "If you don''t tell me, I forgot. Do those fish lay eggs?" Chen Xin inquired about the fish in the greenhouse, but he valued them very much. At the beginning, he asked Li Wensheng for a mixture of male and female in order to breed new fry.


    However, for this problem, Mo Qingyan shook her head and said: "at present, I haven''t seen spawning. Maybe it''s not the breeding season, but I don''t know how to raise fish. I have to ask someone to find out about it."


    "OK, let''s do it first. You can plant whatever you want to eat, long Niang." Chen Xin is not entangled in this matter, those fish will always raise small fish, nothing more than wait and eat.After chatting with Mo Qingyan, Chen Xin also plans to go to the greenhouse to have a look, so he goes to the greenhouse with her.


    In the greenhouse, the six layers of hydroponic planting layer still looks magnificent, and a group of swimming fish in the pool at the foot also looks very healthy. If the two layers of hydroponic planting layer had not just been harvested, it would be like a planting factory in science fiction.


    After checking all the places in the greenhouse and the growth of all kinds of crops, Chen xinlai was most concerned about the chicks in the cage.


    Now these chicks have grown up, and they begin to grow up. They are chicks, not chicks.


    Qin LAN took care of these chicks, but before Qin LAN went to the city with Chen Xin, they were taken care of by Mo Qingyan. Now it seems that they are all growing well. The hen lies in the breeding cage. Qin LAN used to make a chicken nest with straw for it, and it looks like there are eggs under the bottom.


    When Chen Xin saw this, he immediately opened the lid of the cage and planned to reach in and touch the eggs.


    However, before Chen Xin''s hand reached in, Mo Qingyan slapped his hand: "don''t move! This egg is specially reserved by me to hatch chickens

 Chapter 326

    Chen Xin''s leisurely life at home didn''t last long. However, he spent three or two days in his shelter, and just dried the vegetables that needed to be made into dehydrated vegetables. Before he could put them away, people from scientific research institutions came to him and told him that the production line of isotope thermoelectric battery had been installed and debugged.


    Hearing this news, Chen Xin didn''t dare to neglect it, so he simply explained what happened to his shelter and took Han Ping back to the city.


    With the people of scientific research institutions riding snowmobiles back to the city, Chen Xin and Han Ping are well protected by exoskeleton protective clothing, but the staff who came to pick them up were obviously very cold.


    This obviously makes these staff very envious of Chen Xin''s equipment. Unlike them, they can only wear as much as possible.


    Of course, the clothes on these staff members are also very warm, not only down jacket and windbreaker, but also sweaters and thermal underwear.


    The clothes on the field workers like them have been the same as the equipment of the Antarctic scientific research team members, and there will be no frostbite or damage due to insufficient clothes.


    Even if the temperature is now more than minus 50 degrees, as long as you wear a thick sweater, you can still resist the cold.


    But how can this degree of clothing keep warm compared to the exoskeleton protective clothing worn by Chen Xin and Han Ping? It''s heated by electricity. It''s more comfortable than the protective clothing that is heated by electricity, which is windproof and warm.


    It''s just admiration. The country has begun to imitate Chen Xin''s exoskeleton protective clothing, but it still takes time to imitate. It''s almost impossible to distribute it to these field workers in a short time. They have to wait for a while before they want to wear such protective clothing.


    Chen Xin and Han Ping entered the small shelter, which has been completely transformed. After entering, there are not only strict safety inspection, but also special radiation protective clothing, dust removal and disinfection to ensure the cleanliness and safety of the production area.


    "Mr. Chen Xin, you are here at last. Everything is ready. You are waiting for the final debugging." Seeing the arrival of Chen Xin, several researchers who had been waiting for a long time welcomed him.


    "Is all the equipment in place?" Chen Xin said hello to the researchers and asked about the business.


    "All the equipment has been installed and debugged, and now it can be put into use. However, in terms of process parameters, because we still use the experimental parameters given by the laboratory, we have not yet carried out trial operation." The scientific research personnel talked about this matter with Chen Xin in a serious manner, and they still had worries that could not be covered up completely.


    It''s not that the scientific researchers have no confidence in Chen Xin, but that this kind of production is not to be joked or careless.


    The country has invested so much energy in this matter, even in the case of Blizzard, it still invested a lot of resources to build this production line. Although it was known that there was a problem with the process parameters at the beginning, it was also prepared to waste part of the materials to test and find out the correct process parameters, but the process parameters were even a small error It may cause serious safety accidents, and the scientific researchers are obviously not at ease to do so directly.


    What''s more, in this kind of environment, every resource is very valuable. If we can not waste it, naturally no one wants to waste it.


    "Don''t worry, I''ll have no problem when I come. It''s relatively easy to adjust the process parameters." Chen Xin is confident about this, and is not as worried as the researchers.


    Neither side continued to talk nonsense. After Chen Xin asked the researchers a few more questions, he was ready to enter the production area.


    Since Chen Xin wants to enter the production area, he naturally has to change his protective clothing.


    According to the rules and regulations, he and Han Ping removed the exoskeleton and helmet together, put on special radiation protective clothing with the help of the staff, and entered the production area after strict dust removal and disinfection procedures.


    In the production area, all the equipment has been installed, and the lighting system powered by isotope generator is bright, which makes the whole production area shine like day.


    It''s a long time since the end of the world, where there is darkness everywhere and only man-made lights can bring a little light.


    Chen Xin also can''t help looking up at the fluorescent tubes installed on the ceiling, feeling as if they were separated from each other.


    However, he soon put these ideas out of his mind, with Han Ping and scientific research personnel, Chen Xin began to inspect these production equipment.


    Chen Xin''s check is different from others. He just opens the upgrade interface of the system and checks the number of survival points needed for upgrading all devices.


    Unlike previous upgrades, this time Chen Xin didn''t want to make a big change or qualitative leap in the whole set of equipment. He just adjusted the process parameters of the equipment. Strictly speaking, this is also an upgrade. It''s just a small upgrade, not a big change.


    The corresponding consumption of survival points is not much, even if Chen Xin does not invest materials to reduce the consumption of survival points, the survival points needed are not much.


    However, even if it is not much, Chen Xin will not waste his survival. He turns the whole production area around. After seeing all the production equipment, he chooses to upgrade it as a whole. He only improves the production process and technical parameters, and makes small changes and improvements to the equipment production efficiency, so as to adjust the process parameters and improve the production efficiency The purpose of the project.Chen Xin must restrain himself from changing the whole production line into a fully automated production line, because in that case, the consumption of resources and survival points will completely exceed expectations, and this is not conducive to the promotion of this production line across the country, contrary to the original plan.


    After all, according to the plan, the process parameters should be adjusted with the help of this production line to ensure that the isotope thermoelectric battery produced can achieve the expected performance, and then the new production line should be copied in other places.


    Therefore, Chen Xin can not upgrade the production line on a large scale, but can only make small adjustments.


    Fortunately, this is not difficult. As long as you control your thinking, you can achieve the purpose of adjusting and upgrading the scheme.


    As for the materials needed for this upgrade, as long as Chen Xin opens his mouth, naturally someone will send them to him.


    After getting the upgrade materials, Chen Xin did not delay, and directly used the upgrade function for the whole production line.


    Although it is a small upgrade and materials are prepared, the upgrade of this set of production line still uses up 2000 survival points of Chen Xin.


    Fortunately, the effect of the upgrade is absolutely satisfactory. After looking at the green light, Chen Xin said to the researchers, "I''ve finished the adjustment. Let''s get ready for trial operation."

 Chapter 327

    The so-called trial operation is to run the test for a period of time before the formal operation, so as to find and deal with the possible problems.


    This is very common in production. After all, there are always differences between theoretical design and actual operation. No one knows what problems will happen.


    After Chen Xin announced the completion of the adjustment of the production line, the trial operation of this isotope thermoelectric battery production line will naturally be carried out.


    There is nothing to say about the trial operation itself. Let the workers turn on the equipment and operate it according to the actual operation. As long as there is no problem and the equipment runs smoothly, the trial operation will naturally turn into formal operation.


    After a strict selection and training of workers in accordance with the rules and regulations wearing protective clothing to complete the cleaning and disinfection, which entered the plant their own jobs.


    For these workers, it may be very dangerous to work in this radiation environment, but such a job, which does not need to go out to face the storm, but also pays well, is very valuable in this end. No one will be foolish enough to make mistakes and be fired or give up such a job.


    One person''s job, which can satisfy the whole family, is very rare in this last days.


    As I said earlier, the food in the shelter is graded. If you want to get enough food, you have to work. But even the best paid field personnel don''t have more preferential treatment. It''s just that there are two more energy bars in the food, which can be eaten by themselves or distributed to their relatives.


    But the salary of this production line is that you can get double rations, even if there is no energy bar food, which is enough to make a family of three or four full.


    So everyone who can come to work on this production line wants to do their work well.


    Chen Xin, standing in the general control room, watched the workers enter the work position through the monitor. Then he said to the researchers who were waiting for him: "when you are ready, let''s start."


    "All right." The scientific research personnel answered, then picked up the loudspeaker on the operating platform and yelled to all the people on the whole production line: "preparation for trial operation of equipment, attention of all departments! Ready to start


    "The power system is normal, the equipment is electrifying!" In front of the console in the main control room, a staff member reported loudly.


    "Switch on, power on! Ready to feed The scientific research personnel in charge of the command issued new instructions in a hurry.


    Through the monitor, Chen Xin can see that with the issuance of this order, the raw materials already prepared have been put into the feeding port of the production line.


    Looking at these pictures, I feel the serious atmosphere of the staff around me. Although there should be no problems after the system upgrade of this production line, Chen Xin can''t help looking forward to and getting nervous because of the atmosphere.


    "Ready for feeding!" A staff member reports.


    "The power on of the device is normal, it can be started!" Another staff member looked at the console and saw that all the lights were on. Then he called out.


    "Start the production line! All departments should pay attention to monitoring! " The scientific research personnel in charge of the command issued the start instruction, and at the same time pressed the red button to start the production line from the console of the main control room.


    As the button is pressed, all the equipment in the whole production line is running.


    At the end of the production line, Chen Xin and the researchers are all nervously around.


    The first isotope thermoelectric battery produced by this production line is about to leave the production line. Everyone is waiting nervously and expectantly for the completion of this battery.


    The researchers are worried about whether the battery can meet the expected quality requirements.


    Although the first batch of products produced in the trial operation of the production line may not be satisfactory, researchers still have great expectations for the first isotope thermoelectric battery, hoping that it can achieve the expected performance.


    Soon, a silver white battery was sent to Chen Xin and others along the conveyor belt of the production line. On the display screen on the side of the battery, a green light belt was particularly eye-catching, indicating that the battery is in good condition.


    Two researchers who had been waiting for a long time quickly reached out and lifted the battery to one side for testing.


    "Radiation is normal." A researcher took a Geiger counter and scanned the battery carefully. The Geiger counter didn''t alarm.


    Because radioisotope charging is used, the battery itself has radiation. If the production process is not up to standard and the sealing is not enough, the battery will have radiation leakage, which will be very dangerous.


    Now the battery has passed the test of Geiger counter, which undoubtedly makes everyone feel at ease. At least the quality of this battery is qualified in sealing.


    The next step is to test the power of this battery, which is also the most concerned topic of all present.


    After all, this thing is made to get energy from it. If the thing made is equivalent to the 10kW battery with output power trial produced in the laboratory before, although it is not unusable, a 10kW battery and a 100kW battery are obviously used differently.As expected, the battery produced by the production line is required to achieve at least 120 kW output power. Although there is still a gap with Chen Xin''s 160 kW output power isotope thermoelectric battery, the output power of 120 kW is enough to meet the vast majority of use.


    The researchers connected the battery to the instrument and began to test. Everyone''s eyes focused on the instrument, waiting for the measurement results.


    "Output power 120! 120KW£¡ Stable output The staff in charge of the measurement looked at the rising reading, and the whole person was excited and loudly reported the data displayed on the instrument.


    "It''s a success!" Many researchers are excited to jump up, cheering loudly.


    Although it''s not an exciting project, it''s still a matter worthy of everyone''s cheers and celebrations to build this production line after working so hard for a long time and in the case of a blizzard.


    "Hurry to record the process data and send it to the laboratory!" When everyone cheered, the scientific research personnel in charge of the command obviously did not forget the important things, and asked several other scientific research personnel to record the process parameters first.


    Chen Xin watched them continue to work with the joy of success, and his heart was filled with an indescribable sense of achievement.

 Chapter 328

    The smooth production of isotope thermoelectric battery is not only good news for Chen Xinhe''s researchers, but also a very important thing for this city, even for the whole Hunan Province and even for the country of Yan.


    This means that in this era, Yanguo is the first to get rid of the energy constraints of the old era.


    To put it more bluntly, instead of burning coal, Yanguo can rely on nuclear power to meet the energy demand in this extremely cold end.


    In the field of nuclear power, the most widely used radioactive element is uranium ore. The energy produced by the fission of uranium-235, a natural isotope in nature, is equivalent to the heat released by the combustion of 2700 tons of standard coal.


    Before the disaster, Yanguo was one of the top ten uranium producing countries in the world, with an annual output of more than 1600 tons.


    Uranium itself is also a kind of element widely existing in nature, and its content is higher than that of gold and silver. As long as we master the use of uranium, we will not have to worry about the energy problem at all.


    For Yanguo, having an isotope thermoelectric battery means that they can generate two batteries from one shelter. In the next ten years, this shelter will not have to worry about energy at all.


    Before the isotope in the battery decays, the battery will provide enough power for the shelter.


    And let the country''s refuges get rid of the dependence on coal, which means that the country can liberate a lot of human and material resources used to maintain coal transportation.


    Instead of using most of the transport capacity to maintain coal supply, railway transportation can transport more production materials.


    Instead of burning the coal directly, the mining sector can use the coal instead of oil, coal gasification and other coal chemical industries to produce more industrial raw materials and accelerate the recovery of industrial production.


    It can be said that if there is no need to provide coal for heating and power generation for shelters across the country, the post disaster reconstruction speed of Yanguo can even double!


    It is precisely because of the importance of isotope thermoelectric battery that the successful operation of the production line makes these researchers so happy.


    In order to celebrate this event and to thank Chen Xin for his contribution to the construction and operation of this production line, the person in charge of the scientific research personnel specially took Chen Xin and said that they would invite him to dinner and thank him very much.


    However, Chen Xin refused, and this was indeed something to celebrate, so he agreed.


    followed the leader to a lounge. The leader took out a bottle of Baijiu and two cans, and got two hot food. This is a big meal.


    Looking at these things on the table, Chen Xin can''t help but raise eyebrows. Before the disaster, these things can only be called make do meals, but in this end of life, these things are really good things.


    There are two tins, one is lunch meat and the other is fish meat. There is no fancy advertisement on them, just a simple black label with the name and production information. As for the production time, it was last month.


    This is not the inventory before the disaster, but the new production. Chen Xin understood this when he saw the production date on the can.


    as for self heating food and Baijiu, this is indeed the stock before the disaster, because these two are now unable to produce because of lack of enough raw materials.


    Now every grain of food is very precious. The main food for the survivors in the shelter is the national grain reserve before the disaster. The supplementary food is the mice and mushrooms raised by the shelter itself, plus the Tenebrio molitor which has been made into protein powder.


    Therefore, the country does not have surplus food to make wine, nor does it have surplus food to raise livestock. Therefore, the wine and self heating food with cumin mutton on on the package can not be produced after the disaster.


    According to the information Chen Xin has learned, the state does keep biological samples in some places, raising some meat livestock such as pigs, cattle and sheep. However, only the top officials of the state and some people who enjoy special treatment can enjoy natural meat.


    Chen Xin can get special treatment if he wants to, but it''s not attractive to him.


    Just as Chen Xin looked at these things, the person in charge also found out two cups, poured a glass of wine for Chen Xin, opened the can on the table, poured water for self heating food and heated it.


    "Here''s to you. Without your help, Mr. Chen, we would not have built such a production line in any case! Thank you for your contribution to our country The person in charge touched Chen Xin with the cup, then killed the wine in the cup.


    Looking at the excited look of the person in charge, I can''t help but feel a bit trance and surprised. In his impression, the person in charge has always been a very serious look, usually not smiling, and rarely showing any expression.


    However, with the downfall of alcohol, the person in charge also opened his mouth to Chen Xin: "to tell you the truth, I envy those ancestors in those years. Although their conditions were hard, people at that time were energetic. Although they were lack of material conditions, they were rich in spirit!They fought against heaven and earth and built our country today with boundless fighting spirit and pride, which is the envy of our younger generation! The reason why I chose this job at that time was that I wanted to contribute to the country like my predecessors! "


    "We can''t say that. Aren''t we also contributing to our country now?" Chen Xin can understand the idea of the person in charge. Although with the enrichment of material life, many people are pursuing enjoyment, there are still such a group of people who are dedicating their youth and blood to the country.


    "I can''t compare with those ancestors. I''ve wasted most of my life, but I''ve done something trivial for my country." The person in charge''s eyes were moist, and his emotion was even more excited: "I really want to thank you, Mr. Chen, for giving me such an opportunity to contribute to the country! This is really the chance I''ve been looking forward to for half my life! Thank you


    With that, the person in charge took Chen Xin''s hand and shook it two times.


    Through the power of the palm, Chen Xin can feel the sincerity of the person in charge.


    "You''re serious. I just did what I could. It''s not worth your praise." Chen Xin was embarrassed by the person in charge and said modestly.


    "Ha ha, Mr. Chen, you are modest! Maybe it''s people like you who can better contribute to our country? I''m still vain. I always want to do something big. I''m not satisfied with what I''ve done... " The person in charge shook his head, sighed and raised his glass again: "no, thank you, thank you for all this!"


    Then the two wine glasses met.

 Chapter 329

    A bottle of Baijiu is not what good wine, Chen Xin and the responsible person are all very happy.


    On the one hand, today''s event is really worth celebrating. On the other hand, it''s no better than before. Even if it''s not a good wine, it''s wine.


    Some drinks are already good, and neither Chen Xin nor the person in charge have the idea of being choosy.


    There are wine and vegetables. Two men get together again. When they get drunk, they naturally chat.


    However, Chen Xin and the person in charge didn''t talk about any irrelevant topics. What they discussed was still related to the current situation and the national economy and people''s livelihood.


    "Now that the whole world is frozen, where does food come from? You can''t just grow mushrooms in shelters to raise mice, can you? Isn''t that enough to eat? " Chen Xin has always been concerned and worried about this issue.


    He sipped a sip of wine and explained to Chen Xin, "the state has considered this matter before the disaster, so in the three months before the disaster, the state has built large-scale grain planting greenhouses and breeding areas in the mountainous areas of Lingnan and Qiongzhou to ensure the food supply after the disaster ¡£¡±


    "It turns out that the country has a plan for a long time, but I''m not worried about it." When Chen Xin heard the person in charge say so, he felt that the stone hanging in his heart had fallen to the ground.


    Although he does not worry about food and drink, in case of a national food crisis, it will have a great impact on him.


    "The plan is done, but these things can''t guarantee to feed everyone in the country." However, for Chen Xin''s words, the person in charge shook his head and denied: "how many survivors are there in the country? Lingnan and Qiongzhou alone can''t feed so many people.


    According to the previous statistics, the output of Lingnan and Qiongzhou is only enough to meet one-third of the national food consumption. Each shelter grows its own mushrooms and raises mice, which can fill about one-fifth of the gap. The rest You can count the difference yourself. "


    The person in charge didn''t finish what he said, but he shook his head helplessly.


    Hearing this, Chen Xin can''t help but be surprised. He didn''t expect that the country would have such a big grain gap.


    Although he had guessed that there might be problems with grain before, Chen Xin only thought that he would be a little nervous, but he didn''t expect that he would be short of two-thirds directly.


    This is not a small number. If the problem is not solved, it means that at least half of the people in the country will starve to death!


    "This Does the state have any measures to deal with it? " Chen Xin asked with concern.


    If the problem is so serious, the country must have measures to deal with it. It is impossible to really watch more than half of the people in the country starve to death.


    "There are some countermeasures. After all, the country can''t really watch so many people starve to death." The person in charge nodded. When it came to this problem, he gave Chen Xin a serious toast. Then he continued: "thank you, Mr. Chen, for this matter. The emergence of isotope thermoelectric battery can solve many problems! With sufficient energy, it''s much easier to build a new greenhouse or maintain the operation of the existing greenhouse! "


    At this point, the person in charge seemed very happy, filled himself and Chen Xin with wine, and continued: "in fact, the country had a plan at the beginning, but three months before the disaster, the country''s main energy was on the defense of meteorites, and these plans were not easy to make on a large scale. At that time, everyone thought just in case. After all, if the meteorite defense was successful, there would be no such plan So much.


    So the national plan at that time was to use grain reserves for a period of time after the meteorite fell, and then build large-scale greenhouses in the central Sichuan plain and the Qinghai Tibet Plateau during this period to fill the shortage of grain production.


    However, because of the energy problem, the implementation of this plan has not been very smooth. Most of the transport capacity of the railway has been limited. It is necessary to maintain the national coal supply. In addition, the transportation of materials on the Qinghai Tibet Plateau is difficult. This plan is only carried out in the central Sichuan plain as planned. "


    Hearing this, Chen Xin knows a lot. According to the original national plan, the whole plan was obviously divided into two parts. Before the disaster, he spared no effort to build large-scale planting and breeding areas in Lingnan and Qiongzhou, which are close to the tropical areas, and relied on the temperature in the tropical areas to maintain agricultural production after the disaster.


    After the impact of the meteorite, a second large-scale planting and breeding area was built in the Shuzhong plain and the Qinghai Tibet Plateau, which were not seriously affected by the mountain area, to make up for the shortage of production in Lingnan and Qiongzhou.


    As for each shelter growing its own mushrooms and raising mice and Tenebrio molitor, this is the third part of the plan prepared to fill the gap between the first two.


    If everything goes according to the state''s expectation, the food problem may arise, but obviously it will not be too serious. However, according to what the person in charge has said, the plan is obviously not going very smoothly.


    "In that case, is it not food or will it be tense?" Thinking of this, Chen Xin became more and more determined in his mind to engage in large-scale cultivation of greenhouse: "in this case, I have an idea to engage in greenhouse cultivation, which should also be able to solve some food shortages for the country?"


    The person in charge wanted to say that with the isotope thermoelectric battery provided by Chen Xin, the national plan could be smoothly carried forward, and there would not be food problems. However, hearing that Chen Xin also had the idea of planting greenhouses, he immediately stopped talking and asked him, "Mr. Chen, what are you going to do?""At present, I just have an idea. I plan to dig a well to bring the deep geothermal energy to the surface to form a thermal field, and then build a greenhouse to keep the heat. In this way, I can have a planting environment and grow food crops." Chen Xin just gave a brief account of his idea, without giving a detailed explanation of how to do it.


    However, even if it was just a simple idea, the person in charge understood what was going on as soon as he heard it. After a little thought, he nodded his head and felt that the idea was feasible.


    However, although it is feasible, it may not be realized.


    "But how can we get deep geothermal to the surface? The country does have geothermal related technology, and because of the end of the world environment is also vigorously developing related technology, but want to effectively use the deep geothermal this is not easy ah The person in charge frowned. Even though Chen Xin had been outstanding, he didn''t think this problem was easy to solve.


    "Dig deep wells into the ground, and then use the air for heat exchange to bring heat to the surface." Chen Xin gave his own plan, but he also said to the person in charge Ming: "but these are just my ideas. At present, I haven''t figured out how to realize them."


    However, Chen Xinqian''s eyes lit up: "what you said is hot dry rock technology?"


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 330

    Deep geothermal is a new energy technology which was studied in the federal government around the 1970s.


    Its main principle is to guide the heat contained in the dense and impermeable high-temperature rock mass at the depth of 2000-3000 meters underground to the surface through drilling, water injection and other means, and use it in the fields of heating, power generation and so on.


    This technology is favored because of its low cost, clean and recyclable advantages. It has been promoted and applied in many countries with abundant geothermal resources. However, limited by the speed of development of technology, this technology has not formed a mature utilization system until this century.


    "The utilization of deep geothermal in China started relatively late and formed a considerable scale only after the technology matured in recent years." The person in charge seems to know a lot about this area, and when he talked with Chen Xin, he was also gushing: "a few years ago, a national new district in Chang''an adopted this kind of deep geothermal well as a heating method, which is a successful case of China''s utilization of deep geothermal resources. After that, high temperature dry hot rock was produced in Qinghai, and China is in the forefront of the world in this area."


    "Is deep geothermal energy only used in China these years? But I remember when I was still in primary school, Yangbajing in Tibet province should have been built geothermal power generation, right? Isn''t that deep geothermal development? " Chen Xin is a little strange. In his mind, Yang Bajing was very famous when he was still in primary school.


    In the face of this problem, the person in charge shook his head with a smile, and then explained: "Yangbajing in Tibet province belongs to medium temperature shallow geothermal, where the geothermal resources are basically ready-made, and there is no need to drill deep wells to make use of it. However, Yangbajing''s geothermal power generation is very early indeed. In the 1990s, megawatt geothermal power generation was realized, which is also a famous case of geothermal development. "


    "I see. Shallow geothermal and deep geothermal are not the same thing." Chen Xin nodded clearly, quite a sense of sudden realization, but he then asked: "the high-temperature dry hot rock in Qinghai, is it of high utilization value? Is the country technologically mature in this area? "


    Chen Xin is very concerned about this problem. If the country has ready-made technology, his idea of building energy towers to build greenhouses and even district heating fields will be easier to realize.


    "Ha ha, that''s the point you''re asking!" For this problem, the person in charge seems to have been scratched to the itch. The whole person is excited. He adjusts his sitting posture and takes a sip of wine. Obviously, he plans to have a good talk with Chen Xin.


    Chen Xin also made a serious attitude to listen, want to have a good understanding of this knowledge.


    "For many years, the total amount of geothermal utilization in China has been the first in the world, but it mainly focuses on the utilization of shallow medium and low temperature geothermal. For deep geothermal resources, on the one hand, there is a lack of relevant technology, on the other hand, there is a lack of resource exploration. It is only in recent years that the country has made many breakthroughs in this regard." At this point, the person in charge sighed a little, not only sighed: "geothermal resources are good things! Its application cost is much lower than solar energy and wind energy, and it is clean and environmentally friendly, with huge reserves!


    Especially in China, there are about 856 trillion tons of standard coal in the dry hot rock resources at the depth of 3-10 kilometers in the mainland, accounting for about 16% of the world''s resources. It is a pity that China has not conducted research and development on this kind of energy before. Until the discovery of dry hot rock resources in the Qinghai Tibet Plateau, it fills the gap that China has not explored and discovered dry hot rock resources. "


    "In this case, why didn''t the state consider large-scale exploitation of dry hot rock and use deep geothermal to build shelters to avoid this crisis?" Chen Xin suddenly felt strange. According to the person in charge, it is easy to exploit the dry hot rock resources and the application cost is low. It is reasonable that the country should exploit them on a large scale. Why is it still burning coal now?


    For this problem, the person in charge is a wry smile: "don''t you want to be a country? The southern part of the Qinghai Tibet Plateau accounts for about 15% of the total dry hot rock resources in mainland China. The state plans to build planting and breeding areas in the Qinghai Tibet Plateau, and the plan is to use geothermal energy for heating and power generation. However, the construction environment on the plateau is too bad, and the plan is advancing very slowly.


    Besides the Qinghai Tibet Plateau, the Songliao Basin, the Bohai Bay Basin and the southeast coast are all frozen by the rising sea level. In this case, it is very difficult to develop and apply the deep geothermal resources on a large scale. "


    Hearing this, Chen Xin nodded clearly. The sea water has poured into Dongting Lake. Shandong Peninsula has become Shandong island. Now it is not very practical to develop geothermal resources in coastal areas.


    However, although there are many difficulties in this aspect, the utilization prospect of deep geothermal is still broad.


    Chen Xin thought about it seriously and then said, "since the country has the technology in this area, it should be no problem for me to use geothermal resources to build a greenhouse for planting, right?"


    "That''s hard to say." The person in charge shook his head and filled Chen Xin''s glass with wine. Then he continued: "the deep geothermal technology currently used in our country is mainly used for the development of dry hot rock, that is, impermeable rock with no fluid or a small amount of fluid.Specifically, by injecting water into deep wells to develop fractures, a planar artificial dry hot rock heat storage structure is formed, and heat is extracted by recovering high-temperature water and steam. This technology requires the geological structure. In places like Hunan Province, where the groundwater resources are too rich, if you want to exploit the deep geothermal resources, you need to change the technology, but there are many problems! "


    "Let me solve the technical problems. As long as I can put up the shelf, I can make it practical." Chen Xin didn''t think it was a problem.


    With the support of the system, it is not difficult to exploit the deep geothermal.


    "I forgot Mr. Chen, what you are good at most is technical improvement!" The person in charge gave a smile, patted his head and made a promise: "since Mr. Chen, you have such an idea, I''m willing to give my full support. After that, I will reflect the situation with the higher authorities and strive to set up a pilot here. At that time, Mr. Chen will need you to improve the technology.


    If this can be done, the development technology of deep geothermal resources can be popularized on a large scale, which will benefit the country and the people! "


    "I''ll wait and see!" Chen Xin raised his glass and touched the person in charge again.

 Chapter 331

    "Awake? Drink some water. "


    Chen Xin opened his eyes and saw a cup of hot water in front of him and a red mechanical prosthesis holding the cup.


    "Ah LAN? What are you doing here? " Chen Xin sat up from the sofa and rubbed his forehead. Then he woke up. He took a drink from a water cup and diluted the sour taste in his mouth. At the same time, he asked Qin LAN who didn''t know when to come.


    At the same time, he also remembered that he had drunk with the person in charge before. He drank a little too much and fell asleep on the sofa in the lounge.


    Thinking of this, Chen Xin looked at the table next to him and saw that the mess had been cleaned up.


    "I came to see you, but they said you were drunk. I''m here to watch you." Qin LAN explained the reason why he appeared here, took the cup that Chen had emptied and asked, "do you want more?"


    "Well, a little thirsty." Chen Xin nodded and motioned to Qin LAN to pour him another glass of water.


    Qin LAN nodded and got up to pour water from the kettle. She also asked curiously: "I haven''t seen you drunk for a long time. How are you in a good mood?"


    He took the cup Qin LAN handed over and drank it dry again. Chen Xin nodded: "OK, it''s mainly because he was engaged in chatting, so he drank two more cups unconsciously."


    Hearing Chen Xin say so, Qin LAN sat beside him again and shook his head with some disapproval: "drink less wine, it''s bad for your health. Pay attention next time."


    "Well, I see." Chen Xin agreed to come down, wake up, this just stood up from the sofa.


    After straightening out the folds of his clothes, Chen Xin asked Qin LAN, "yes, what about Han Ping? Didn''t you see him when you came? "


    "He stayed outside all the time when you were sleeping. I told him to take a rest when I came." Qin Lan also stood up and helped Chen Xin straighten his collar, but smelling the smell of wine on his body, he said with some displeasure: "you smell so bad. Go to take a bath and change into clean clothes."


    Hearing Qin Lan''s words, Chen Xin''s expression has become a little strange.


    He took a look at Qin LAN, didn''t say much, just nodded and walked towards the door.


    Looking at Chen Xin left the room, Qin LAN just reflected that her words just now seemed too close to Chen Xin.


    Aware of this, Qin LAN blushed, but soon calmed down.


    For her, if she really wants to get back together with Chen Xin, she will never be shy.


    Chen Xin, who left the room, found a staff member and asked him to help him with a clean suit. Then he went to the bathroom.


    This place was originally a refuge. Naturally, there were perfect bathroom equipment. In the previous transformation, these equipment were retained, and even upgraded and optimized.


    According to the management regulations, since the products produced here are products with radiation, the necessary radiation decontamination measures still need to be done, and there are certain requirements for sanitary equipment. After all, not all sanitary equipment can complete radiation decontamination.


    When he came to the bathroom, Chen Xin took off his dirty clothes with the smell of wine, took the bath supplies given to him by the staff just now, found a compartment and prepared to take a bath.


    These bath products are all new, including soap, which is unopened, which makes Chen Xin, who is a little bit of a cleanliness addict, very satisfied.


    Although in the last days, with limited conditions, Chen Xin is not unable to accept the use of things used by others, but if he can, he still does not like the use of things used by others.


    Turn on the tap, hot water spilled down, standing under the water to wash his body, wash away the wine gas, but also wash away the heavy body.


    Chen Xin takes a bath very quickly. In fact, he is not allowed to take a bath for too long in this environment.


    Of course, if he is in his own home, he is likely to go to the big bath after washing. Generally, he won''t get up for half an hour.


    After washing his body and changing into clean clothes, Chen Xin left the bathroom fresh and fresh.


    As for the dirty clothes, naturally, I found a bag to put them in and planned to take them to clean later.


    Chen Xin''s clothes are obviously a work uniform here, which can also be regarded as one of the benefits of the workers working here. A whole set of clothes includes washing and changing.


    Of course, this is not a waste of the country''s excess resources. Although we rely on the chemical industry to resume production, chemical fiber textile can ensure that we still have clothes to wear, but the production capacity is not so wasted.


    The main reason for sending out a whole set of clothes here is to work in the production area and need uniform and standardized clothes.


    Don''t think it''s just formalism. In fact, standardized clothing can improve the safety of production to a great extent, because if you wear your own clothes to enter the factory, the non-standard clothing is likely to be entangled and caught by the machine, which may affect the production, or even cause death, and the whole person will be involved in the machine.


    In particular, the production here is isotope thermoelectric battery, which has high radiation. Any potential safety hazard must be eliminated.Wearing a suit of work clothes, Chen Xin returns to the rest room. Qin LAN is sitting on the sofa with her feet up.


    Chen Xin noticed that the clothes on her body were not the same police uniform in the past, but a set of private clothes.


    The dark denim trousers and the light Knitted Top outline Qin Lan''s beautiful figure, and a pair of black boots wrap her legs, making her more slender and slender.


    For Chen Xin, he hasn''t seen Qin LAN wearing a private dress for a long time, because in most of his memory, Qin LAN has always been a uniform, even dating is often a black training suit, just tearing off the armband and police rank on the clothes.


    "Why haven''t I seen you in this suit before?" Chen Xin sat down beside Qin LAN, but he pulled her right hand and looked at the mechanical prosthesis with power gloves. Chen Xin took off her power gloves and checked the prosthesis: "are you still used to using this prosthesis? Is there anything I can help you adjust? "


    "I used to go to work every day. Of course, I had to wear a uniform! Even if I''m dating with you, I have to guard against being called back to work by the team. For convenience, I can only wear training clothes. Now I''ve resigned from the team, so I can wear them at will. " Qin LAN doesn''t care, let Chen Xin check his right hand.


    Hear Qin LAN say so, Chen Xin is to pause for a while, this just appearance seems to ask carelessly: "really quit?"


    "Quit. You''ll support me later." Qin LAN leans on Chen Xin''s shoulder.

 Chapter 332

    On the platform of a railway station in a city, a group of people are waiting anxiously.


    "Isn''t the train late?" Among a group of people, a leader who seems to have been in a high position for a long time inquires the Secretary beside him. Although he knows there will be no problem, he is still a little worried.


    Seeing the leader''s inquiry, the Secretary quickly replied, "don''t worry, mayor. This time we are here is the new nuclear power train put into operation in our country. It won''t be late. The time is almost up. It should be coming soon."


    Hearing what the Secretary said, the mayor didn''t feel much relieved. He also knew what the Secretary said. Asking the secretary was just a psychological comfort.


    Waiting for the train to arrive, in fact, both the mayor and other people around him are worried.


    Since the disaster came, the local governments have been in a state of heavy burden. The survival problem of a city''s population is from hundreds of thousands to millions, which makes everyone nervous and dare not be careless.


    With an idiom to describe that is like walking on thin ice, for fear of making a little mistake.


    But the previous Blizzard still let everyone understand why the old saying goes that there are no two blessings, and disasters never come singly. A blizzard suddenly hit the already overburdened shelter.


    Not all cities are so lucky, someone can improve the boiler, improve the heating efficiency.


    More than one tenth of the city''s people were directly frozen to death in the previous blizzard, nearly 30% of the survivors faced various degrees of amputation threat, and more than half of them needed treatment.


    With the influx of so many patients, the medical system directly collapsed. Many medical staff themselves suffered from the diseases caused by low temperature and needed treatment.


    The urgent need for food and coal also worsens the situation of the city. If it wasn''t for the snowstorm, the comrades on the railway line risked their lives to deliver goods and materials, I''m afraid the city would have been finished long ago.


    Now that the storm has stopped, all the reconstruction work is in a myriad of ways. Although the staff who can still stick to their posts are good and know what to do, the cooperation between many departments still needs to be coordinated.


    As a mayor, he should have dealt with these things in his office at this time, but the goods and materials that came here are particularly important. The state also clearly orders that the mayor himself must receive these goods and materials, which makes the mayor have to put down his work and bring people to the railway station to receive these important goods and materials that he doesn''t know what they are.


    Under such circumstances, we can imagine the mayor''s impatience.


    Fortunately, the train was not late. Just when the mayor was impatient and began to look at his watch frequently, a train finally cut through the darkness and came slowly from a distance.


    Seeing the train appear, everyone on the platform can''t help but draw a breath and finally come.


    The train pulled into the station and stopped steadily on the platform.


    Seeing that the train stopped steadily, the mayor quickly adjusted his mood and expression and walked towards the door. He wanted to see what materials were so important that the mayor himself had to sign for them.


    However, in front of the train, the heavy armor with clear water chestnut and the heavy machine gun and turret on the top of the carriage let the mayor know that the goods and materials are really very important.


    Otherwise, it is impossible to dispatch such fully armed armored trains. It is said that they are still nuclear powered.


    The door of the carriage opened, and a staff member holding documents, accompanied by several armed soldiers, came down to meet the mayor.


    Seeing these people get off the bus, the mayor''s eyebrows can''t help stirring up. It''s not that he doesn''t have enough energy. It''s just that these people''s clothes are too surprising.


    The staff holding the documents are OK, just a silver gray one-piece protective suit with a helmet on their head.


    But the soldiers behind him were dressed differently, with the same one-piece protective suit painted with gray snow camouflage, the helmet changed into a tactical style, and a bunch of equipment that the mayor knew or didn''t know.


    But this is not what surprised the mayor most. If this is the case, the mayor just thinks that the country has made a new breakthrough in protective equipment, and he will not have any other ideas.


    However, these soldiers also have a set of exoskeletons painted with snow Digital Camouflage, and also have the shape of defensive armor to protect the vital parts of the body. Two of them carry a three barrel heavy machine gun on their shoulders.


    "What are the important materials that need to be so fully armed?" The mayor murmured, but he didn''t think much about it. Instead, he directly said to the staff who came by: "comrade, it''s hard work. What kind of materials do you need me to receive in person?"


    Instead of being polite to the mayor, the staff carefully checked his identity. After confirmation, they explained: "it''s nuclear battery. According to the instructions of the state, all shelters will transform the existing coal-fired heating and power supply into isotope thermoelectric battery for power supply and heating through electric heating starting from receiving these materials."


    "What? Battery? Isn''t this nonsense? " As soon as the mayor heard the explanation, his eyebrows flew up. In his mind, the mayor was shocked when he heard the explanation from the staff, which made him a little embarrassed. However, after years of city administration, he stabilized his mood instantly, took the list from the other party, checked the things listed above, pointed to one of the lines and asked, "what are this protective clothing and exoskeleton £¿¡±When the staff saw the mayor and asked, they pointed to the soldiers wearing exoskeleton protective clothing beside them and said, "this is the exoskeleton protective clothing."

 Chapter 333

    In the factory, a new batch of isotope thermoelectric batteries are being packed.


    Each battery was neatly packed into a special fixed box, and the staff attached labels and qualified inspection marks, then it was immediately pulled away. There was no warehousing procedure.


    At present, the materials of the whole country are planned by the state, and the isotope thermoelectric batteries produced here are in short supply.


    A batch of raw materials have been transported by the state, and the finished products have been ordered where to go before they are produced.


    Now the whole factory is in the state of three shifts. It can produce about 100 isotopic thermoelectric batteries 24 hours a day at full capacity without stopping people and machines.


    Trains for transporting materials and pulling away finished products run every three days, which can basically meet the needs of a small and medium-sized city.


    As for large cities, it''s more troublesome. They need two or three trains.


    But even so, more and more cities are weaning themselves from coal as batteries are pulled away.


    Because of the geographical location, the first batch of cities to use battery power are mainly located in Jiangxi Province.


    Although this province is surrounded by economically developed provinces, Jiangxi Province has always been in a backward position in economy. In addition, there are many mountains in the region, so the situation is not very good after the disaster.


    Therefore, in the previous blizzard, the disaster situation in Jiangxi Province is more serious than that in other neighboring provinces and cities.


    The first batch of isotopic thermoelectric batteries were transported to Jiangxi Province, which can be regarded as a real timely help for them.


    During the days when the factory was put into operation, Chen Xin basically lived and ate here, because everyone was "the first time for a big girl to get into the sedan chair". Even if Chen Xin had absolute confidence in the production line produced by the system, he had to watch at any time to avoid problems caused by unskilled workers or other reasons.


    You know, after the plant is running at full capacity, a large number of uranium isotopes will be transported every day as raw materials, and this kind of thing has a familiar name, uranium-235, which is the raw material of nuclear weapons.


    Although these uranium isotopes had been processed into materials before they were transported, and the concentration did not reach the concentration of weapon grade, which is just the concentration of materials loaded in general nuclear power plants, even so, if there is a safety accident, causing nuclear radiation leakage or other problems, it is still not a small matter.


    After all, it''s something related to nuclear. Even if we know it''s safe, we still have a weak mind when we touch it. We will be more careful.


    In fact, in this period of time, the problem is not without.


    Although the workers have been strictly trained before they take up their posts, some big or small problems still occur in the actual production process.


    Some of the problems are not serious. It''s just that the workers didn''t carry out the safety production standard in place. It''s basically gone to emphasize.


    However, some of the problems were due to dereliction of duty, nonstandard operation and direct contact with isotope loading, which almost caused safety accidents. Chen Xin and the person in charge of the scientific research institution were very angry and directly expelled the workers who caused the problems.


    It''s not that they are unkind, but that they must be strictly managed.


    And because of these things, both Chen Xin and other researchers are nervous, for fear that there will be any more problems.


    This also makes Chen Xin do not sleep well during this period of time. He will be awakened by people for various reasons within a few hours of sleep every day, so that he can only find time to catch up when he is busy with what he is doing.


    Because of the irregular work and rest, Chen Xin''s face appeared black circles with naked eyes, and the whole person looked haggard.


    This undoubtedly makes Qin LAN who has been accompanying Chen Xin quite distressed.


    Now that she has resigned, she has nothing to do with herself. In addition, after that sentence was uttered that day, her relationship with Chen Xin has become closer. She has been following Chen Xin these days, completely replacing Han Ping''s bodyguard job.


    Moreover, because of her closer relationship with Chen Xin and her relationship with a woman, Qin LAN not only acts as a bodyguard around Chen Xin, but also takes care of his daily life to a great extent.


    Although Qin LAN doesn''t know how to cook, and she is not that kind of gentle and considerate personality, Chen Xin''s quality of life has been greatly improved.


    As for the change of their relationship, Chen Xin actually enjoys it. It has to be said that there is a person who knows the cold and the heat and can serve you tea. It''s also a novel and enjoyable experience for Chen Xin.


    Chen Xin can see that Qin LAN is learning how to do a lot of things. After all, what she used to hold most is a gun, and many things she couldn''t do before.


    "OK, I''ll do it myself. I''m not disabled enough to have my face washed." After Qin LAN handed over the towel, Chen Xin washed his face, wrung the towel to dry the water stains on his face.


    Qin LAN stands beside Chen Xin and looks at the way he washes his face. He is in a trance.


    She had never served Chen Xin like this before when she was dating Chen Xin. At that time, when they were dating, she was suddenly called away by the phone of the team, which disappointed Chen Xin who wanted to be romantic or romantic.At that time, Chen Xin always said that it didn''t matter, and helped Qin LAN pack up her things, so that she could start immediately, instead of letting Qin LAN do something for him.


    In fact, this is also one of the main reasons for their breakup to a large extent. Every time, conflicts accumulate over time. No matter how good Chen Xin''s temper is, he can''t stand it.


    So in a discussion about marriage, Qin LAN still left halfway, Chen Xin finally broke out.


    After they had a quarrel, it became a matter of course to break up.


    "You said that if I didn''t devote myself to my work, but cared more about you, would we have been together long ago?" Qin LAN empties the water from the basin and air the towel. Then she looks at Chen Xinru who is shaving.


    Hearing Qin LAN say so, Chen Xin looked at her in surprise, but shook his head: "this kind of thing assumption is meaningless, with your character, even if you are willing to care more about me, it''s still a phone call, you have to carry out the task, it won''t make any difference."


    Chen Xin''s words make Qin LAN a little embarrassed, but also understand that his character is really like what Chen Xin said.


    Thinking of this, she couldn''t help but want to make up for Chen Xin, so she went to Chen Xin, took his razor, pressed him on the sofa, rode on it, and said to Chen Xin, "sit down, I''ll help you shave."

 Chapter 334

    "Mr. Chen, here are the technological parameters we have sorted out. Do you have anything else to adjust?" In the office of the factory, the person in charge put a specially reorganized and summarized process parameter in front of Chen Xin.


    Although the factory has been running at full capacity and can produce 100 batteries with the same temperature difference every day, three days is enough to meet the power demand of a city, but the country can not only rely on this production line, this factory.


    Before the disaster, excluding the special three places on both sides of the Taiwan Straits, there were 663 cities in Yanguo, including 4 municipalities directly under the central government, 293 prefecture level cities and 366 county-level cities.


    Even if each city only needs 300 batteries to achieve full power supply, that is, the output of the factory in three days, it will take five and a half years to produce batteries that can meet the needs of 663 cities.


    Among them, there are counties, townships and towns without cities. It is undoubtedly a grand project to make the whole country get rid of the original coal-fired power supply system and use isotope thermoelectric batteries for power supply.


    Although the state does not intend to replace all power supply methods with isotope thermoelectric batteries, it is obviously impossible to expect that this production line can meet the needs of the whole country.


    It is imperative to build a new production line.


    Chen Xin took over the specially sorted out process parameters and carefully read them.


    Although I don''t know much about this, I''ve been in the factory for so many days, and I''ve read the relevant parameters for so many times, and I''ve memorized them.


    After checking it, Chen Xin nodded and handed over the process parameters to the person in charge: "it''s the same as the process parameters we use now. I don''t think there''s anything to modify. Send it to the top. Building a new production line earlier can help more people."


    "All right." After the person in charge collected the process parameters, he asked Chen Xin, "Mr. Chen, now the production of the factory has been stable, do you have any plans next?"


    "The next thing I should be busy with is the geothermal greenhouse planting that I mentioned to you before. The food issue is still very important." Chen Xin thought about it for a while, and thought that the next thing he would be busy with was this: "the previous cooperation projects should also be restarted, right?"


    The cooperation between Chen Xin and scientific research institutions was also affected and interrupted by the blizzard. Now that the Blizzard has subsided, the cooperation will naturally continue.


    "It''s natural that we should be responsible for the cooperation. The country on the side of the factory will send someone to take over." The person in charge nodded.


    This is also a matter of course. The former scientific research personnel are responsible for the production supervision and management of the factory. They can not always be responsible for the production and management of the factory, and then they must be handed over to the professional administrative personnel.


    Chen Xin is also clear about this, did not say much, just ready to pack up things, left here to go home.


    However, just as Chen Xin says goodbye to the person in charge and is ready to pack up, Qin LAN suddenly comes in from the outside with Mo Qingyan.


    "Long Niang? What are you doing here? " Seeing the appearance of Mo Qingyan, Chen Xin was a little surprised, but his heart gushed with some worries: "isn''t something wrong at home?"


    Mo Qingyan has been staying in her shelter. How can she come here suddenly? Could it be something happened at home?


    When Chen Xin was worried, Mo Qingyan came to him and said, "it''s OK at home. It''s Han Ze who received a message for help. It''s from Linshi. My uncle and aunt asked me to come to you."


    "From Linshi?" Hearing Mo Qingyan say so, Chen Xin couldn''t help picking his eyebrows: "what''s going on?"


    See Chen Xin so ask, Mo Qingyan also hastened to explain.


    Linshi is a county-level city under the administrative division of the city, which is much larger than the urban area of the city in terms of area alone, and its population is only a little less than that of the urban area.


    Although it''s a county-level city, it''s almost the same as some smaller prefecture level cities.


    Moreover, in terms of geographical location, Linshi is located in the northeast of the city, which is just the traffic throat from Hubei Province to Hunan Province.


    However, although the location of Linshi is very good, because it is only the lower administrative unit of the city, and the two cities are close to each other, there is only a very small railway station in Linshi, and most of the trains do not stop here, so the geographical advantage of Linshi has not been brought into play.


    If it is before the disaster, the impact may be nothing more than a certain impact on the economic development of the neighboring city. After all, both high-speed railway stations and airports are built in the city rather than the neighboring city, and the residents of the neighboring city may have to travel around the city.


    But after the disaster, it has brought a very serious impact to the city.


    The small railway station can only bear the loading and unloading work of the materials needed by the whole city. Many times, it even has to load and unload the materials on the train directly outside the railway station. It is impossible for the train to load and unload the materials on the platform.


    Before the blizzard, for Linshi, it was no more than a little trouble in loading and unloading materials. They were also actively expanding the platform of the railway station and building loading and unloading stations to facilitate the loading and unloading of materials.But with the coming of the blizzard, the small railway station in Linshi was buried under the snow with the platform.


    This undoubtedly brought a devastating disaster to Linshi.


    When the Blizzard is raging, it''s really fatal to use manpower to load and unload materials in the face of the severe cold of more than minus 70 degrees and the gale of level 12.


    Every material loading and unloading can be said to be filled with human life.


    It can be said that in this blizzard, the disaster situation in Linshi was quite serious.


    After the disaster, although Linshi actively organized production and self-help, the damage caused by the blizzard was too serious. The municipal government of Linshi had tried its best, but it was still quite helpless.


    Without the assistance of external forces, Linshi is likely to be unable to survive.


    With all the official power, we can imagine what a private sanctuary would be like.


    So it''s no surprise that Han Zehui received a distress signal from Linshi, although it came from Chen Xin''s former friends living in Linshi.


    "You mean that the" well diggers "in the group used to send signals for help. The situation in the city is very bad now. He hopes that we can find a way to help them?" Chen Xin summed up what Mo Qingyan said and asked her back.


    Mo Qingyan nodded: "Daren said that the situation in Linshi is very bad now. A shelter was even buried by the previous snowstorm. There are too many people who are sick. They are short of medicine and can''t support them any more."

 Chapter 335

    "Can he ask me for help? But the question is, "what can I do for him?" After listening to Mo Qingyan''s request for help from Linshi, Chen Xin didn''t immediately go to rescue people.


    Hearing this, Qin LAN and Mo Qingyan did not express any dissatisfaction, because this is the truth.


    Perhaps now Chen Xin''s cooperation with the state and his system as a plug-in enable him to help his friends in the city.


    But only in terms of his personal ability, without computing the system plug-in, I''m afraid that this kind of time can only help.


    Chen Xin is able to understand that the city''s "well digger" asks him for help. After all, after the snow disaster, he is facing difficulties, so he can only ask his friends who can still be contacted for help, because this may be his only way to ask for help.


    But the problem is still that one. What can Chen Xin do?


    "Or what he wants me to do for him? If he can''t survive, I hope I can help him out. It''s easy to say, just drive a car, pick him up and send him to the official shelter. " Chen Xin is still willing to help his friend on this point. It''s not a particularly troublesome thing for him to go for a trip: "but if it''s other help, I don''t know if I can help him."


    Mo Qingyan shakes her head and explains to Chen Xin: "he can survive, but the current situation of Linshi is He asked for help, which means that he hopes to convey the situation of the city to the municipal government through you, and organize forces to rescue. He also knows that personal power is limited, so he hopes that we can seek help from official channels. "


    "Seek help from official channels? Strange, if Linshi really can''t support it, why don''t the leaders of Linshi directly ask for help from this city? It is impossible for the municipal government or the provincial government to sit by and ignore it. " Chen Xin frowned, which was really strange.


    Even if the city asks for help, there are official channels to go. The traditional red phone of Yanguo is not a decoration. In this case, it''s normal for the city government to ask for help from the superior city or provincial government. It''s also very convenient and direct. There''s no need to go around such a big bend through the folk channels.


    Even if Chen Xin was able to convey the message to the municipal government, it would be difficult to explain all the information clearly. Even if the municipal government wants to send forces to rescue, it needs to send people to find out the situation first.


    This time, the trouble will not be mentioned. The key delay may make some people face the difference between life and death.


    "I think he may be compassionate. Although he can survive, if people around him are in trouble, he will find some ways to help others." Qin LAN, with his professional habit as a policeman, tries to analyze the motives of the helpers: "there should be two possibilities for this matter. One is that the municipal government near the city is unable to ask for help because it is willing to do so. It can only send out help messages through private channels, or because the railway will transport materials to them. The municipal government near the city feels that it can stick to it, so it is not in need The extent of the request for help.


    But for ordinary people, it''s not something they can''t understand that they choose to seek help from the outside world when they are living a hard life. Maybe it''s just the spontaneous behavior of the person you are talking about when he sees the living difficulties of the survivors in the city


    "It''s possible that" Daren "is a person who is very enthusiastic about helping others. If, as he said, the situation in Linshi is very difficult, and there is a shelter buried in the snow, it''s really possible for him to do such a thing." For Qin Lan''s analysis, Chen Xin nodded in recognition.


    However, no matter what the purpose of the "well digger" is to send out a distress message, the current focus is still on how to help Linshi.


    "I think we can report this to the municipal government first and see what the municipal government decides to do." Qin Lan''s idea is more inclined to the official, after all, before or the police, more or less with some procedural habits.


    Moreover, in the face of such a city level disaster, the official rescue force is far more powerful than that of the folk, and it is also more professional in rescue.


    But to Qin Lan''s this proposal, Mo Qingyan has raised the objection actually.


    "I think it''s urgent for us to find out what the situation is in the city first, so that we can have a definite aim. Then, whether we ask the municipal government for help or decide to use other rescue methods, we can have a basis and reference to know what they lack and what they need." Mo Qingyan said, looking at Chen Xin with burning eyes, as if trying to persuade him.


    Seeing Mo Qingyan looking at Chen Xin, Qin LAN turns her eyes to him, waiting for his decision.


    Chen Xin shook his head, obviously not very satisfied with the two people''s plans.


    After thinking about it, he said to the person in charge who had been listening to them: "can you help me contact the municipal government and ask what''s going on in Linshi?"


    "No problem. I''ll call and ask." The person in charge agreed directly and asked, "is there anything we can do for you?"


    As a research institution with high authority, if the person in charge is willing to help, they can mobilize materials through their channels and provide great help.However, Chen Xin still shook his head and did not ask the person in charge for assistance: "the current situation is not clear, even if we need help, we still need to wait until we have a clear picture."


    "OK, I''ll call first." The person in charge had no objection to this, so he turned and left to make a phone call.


    After the person in charge left, Chen Xin explained to Qin LAN and Mo Qingyan, "we don''t know the situation of Linshi at present. Even if we have received the" Daren "signal for help, we can''t make a decision easily even if we know some of the situation. So first, ask the municipal government if we know the situation of Linshi and whether there is a rescue plan.


    If the city government has a rescue plan, we don''t have to worry about it. We should prepare some materials that we can raise by ourselves, and then go there and help the "talent" with our own strength


    For Chen Xin''s response, Mo Qingyan and Qin LAN agreed after thinking about it.


    This is also a relatively safe way to deal with the situation, which can not only understand the situation in time, but also avoid the waste of some unnecessary rescue forces.


    However, while nodding to agree with Chen Xin, Mo Qingyan asked uneasily, "what if something really goes wrong with Linshi?"


    "Then we''ll find a way to go to Linshi, find out what''s going on, and then contact the municipal government to prepare rescue forces here." Chen Xin also has a corresponding plan and response.

 Chapter 336

    The situation of Linshi is beyond Chen Xin''s expectation.


    The situation is really as bad as the "drilling expert" said, because of the snow disaster, the whole city is very seriously affected.


    The important railway station was buried by the previous blizzard. Although the wind has stopped, the loading and unloading of materials still rely on manpower outside the station. At present, Linshi has no way to organize enough manpower to dig out the original railway station.


    The shelter buried by the blizzard in Linshi is also true. Not only one shelter was buried, but almost one fifth of the survivors in the shelter also died in the disaster. Now that shelter has become a tomb of ice and snow.


    And the medical system in the city is now seriously overloaded and completely in a state of collapse. Although it is still in operation, it can not effectively treat a large number of patients with frostbite, hypothermia and other diseases in the urban area. At present, it can only take palliative treatment to delay the time, hoping that the patients can recover themselves.


    Fortunately, the snow disaster has passed, and some mild patients are indeed in the process of self-healing, but the situation of severe patients is still serious, and even a large number of frostbite patients have limb necrosis and need amputation.


    However, the place beyond Chen Xin''s expectation is also here. The municipal government is working hard to save itself. Although they have informed the city of the situation, they did not ask the city to send out rescue teams. They just hope to get more support in materials.


    This is not incomprehensible. After all, if Chen Xin didn''t help improve the boilers in our city, the situation in our city would be better than that in Linshi in the face of this snowstorm.


    Faced with the same medical collapse and the plight of people''s livelihood, even if the city can send rescue forces, it will be very limited. Even if the city calls for help, it will not get much help. It is better to rely on its own efforts to help itself.


    In fact, in addition to the light of Chen Xin and the improvement of the boiler, the situation in the face of Blizzard is relatively ideal. In addition, the situation in most of the cities hit by blizzard in Yanguo is very bad.


    The vast majority of problems focus on the medical system, because the huge number of patients caused by low temperature makes all medical institutions bear the load far beyond expectation, a large number of patients rush into hospitals or clinics, making the vast majority of people difficult to get effective treatment.


    And a large number of patients on the consumption of drugs is also huge, which also led to the vast majority of the city of Yanguo drug emergency.


    At this time, if the pro city to the city for help, its most need is a medical team, can provide help for the already overburdened Pro City medical system.


    As for materials, because the railway transportation has not been interrupted, the market is not very tense in terms of materials other than drugs.


    That''s why Linshi didn''t ask for help from this city, because they didn''t expect to get much help from this city. As for materials, it''s not impossible to have the best.


    After learning about the situation from the person in charge, Chen Xin naturally asked, "does the municipal government have any rescue plan for Linshi now? Now the city should still have the spare power to rescue the neighboring city, right


    "I just asked about this. The municipal government said that it would organize a medical team to visit the city as soon as possible, but how to get there is a problem." Speaking of this topic, the person in charge shook his head, his face is not very good: "at present, the two roads leading to Linshi are all buried by snow and can not pass, although the railway is smooth, but the location of the city and Linshi is too close, the trains stop in Linshi, if you want to go through the railway, you must coordinate the frequency, but this is a very troublesome thing!"


    Chen Xin can understand this very well, because the distance between this city and Linshi is 45 kilometers, and the railway line is a little shorter. In the past, people used to drive between the two cities by road, and it was only half an hour''s drive.


    Although there are two k-prefix trains running between the city and adjacent cities, the average train running time of 70-90km / h is only half an hour.


    Such a short distance is a waste of time even for ordinary trains that are not high-speed trains.


    Therefore, after the end of the world, when setting the frequency, Yanguo railway staggered the city and the neighboring city. The trains that stop in the city will not stop in the neighboring city, and the trains that stop in the neighboring city will not stop in the city.


    The two are staggered to improve the operation efficiency of the train.


    This has resulted in the current situation that although the railway is unobstructed between the city and the neighboring city, there are no trains in fact.


    Under the current situation, it is very troublesome to adjust the railway frequency, temporarily open additional trains, or make a train stop at one more station.


    Because there is not only one train running on the railway, all the trains are running on the railway at the prescribed speed and time according to the plan made in advance. If there is an error in the running time of one train, it will affect the whole railway network.


    And now, compared with before the disaster, there was a perfect communication network at that time. The railway only needs to coordinate in the general control center to control the movement of all trains in the country. A train can stop temporarily or open in time, and there will be no problem.But even so, there are often train delays across the country due to the problems of one train.


    But now, in the case that communication basically depends on cable telephone, there is no way to coordinate the national railway frequency. If a train stops on the railway for a long time, it is likely to collide with the train behind and cause serious traffic accidents.


    This is the same even if there are not so many trains on the railway.


    So in this case, even if the city organized a rescue team or a medical team, it is very difficult to get to the city.


    However, this is not a problem for Chen Xin. He thought about it for a while and said, "it should be OK to take the road. When I went from Hunan Province to Anhui Province, I used to take the road. My car didn''t have any problems. If it was a crawler chassis, I didn''t think it was a big problem when I drove there."


    "The city government also has this kind of consideration, but the road condition information is not clear. It''s very risky to drive there." The person in charge is full of worries. Just because he understands the situation, he knows how dangerous it is.


    However, Chen Xin thought for a moment and said, "if the municipal government has organized a medical team to visit the city, my car should be useful. My car has radar and UAV, which can detect road conditions and avoid many dangers."

 Chapter 337

    Although the municipal government has decided to organize a medical team to support the city, it still needs time to organize, and it can not immediately pull up a medical team to the city.


    And because of traffic problems, it is not easy to go to Linshi.


    According to Chen Xin''s idea, driving along the original road to Linshi is the most feasible plan at present.


    On the railway side, although the municipal government is also making active efforts to coordinate, there are too many things involved, which will not be well coordinated for a while.


    If you have to take the railway to Linshi, you can only get on the train from the city, take the train to three towns, and then transfer the train to Linshi.


    Although this is a highly feasible scheme, it is still lack of practicability at present.


    After all, this time, it will waste a lot of time. Compared with driving directly to Lincheng, it''s a little too troublesome.


    Obviously, the municipal government has also considered this problem, so the municipal government has made two preparations. On the one hand, it has coordinated railway transportation to facilitate large-scale rescue; on the other hand, it has deployed all terrain vehicles that the municipal government can deploy to organize a rescue team to enter the city first.


    After learning the news of the rescue team organized by the municipal government, Chen Xin signed up for the first time, hoping to participate in the rescue team.


    Although he is not a professional medical staff, the reasons he gave are quite sufficient, that is, his previous experience from Hunan Province to Anhui Province, and his RV with radar and UAV as detection means.


    With the help of the person in charge of scientific research institutions, Chen Xin joined the rescue team smoothly.


    The rescue team was successfully established, but it did not start immediately.


    It is not difficult to transfer personnel. At present, the temperature inside each refuge is suitable, the number of patients is maintained at a normal level, and the medical system operates normally. It is not a problem to transfer some doctors to set up a rescue team.


    As for the manpower in other areas, it is not a problem. Under the coordination of the municipal government, all the staff will be in place soon.


    However, for the rescue team, equipment and vehicles are more important than personnel.


    There are naturally professionals in the preparation of medical equipment, and relatively speaking, the main problem facing the city is the lack of medical power. A large number of patients are suffering from frostbite and hypothermia, as well as diseases caused by cold weather. Warmth is the best treatment, and the demand for equipment is not particularly large.


    However, considering the surgical treatment that may be needed for severe frostbite, the rescue team brought a set of mobile surgical equipment.


    This is a new equipment that has been provided to the hospitals in our city in recent years. It is mainly used for medical rescue and temporary operation in case of emergency. It can be regarded as the treasure of pressing the bottom of the box in the hospitals in our city.


    It''s just that the medical equipment is easy, but the car is not so ready.


    Ordinary cars are obviously not qualified for this trip. Even if they use the track assembly Chen Xin made for Li Yulong and put the tire on the track, it''s OK to deal with the relatively gentle snow road indoors. However, they still can''t challenge the mountain road between the city and Linshi.


    Those who are really qualified and capable of this trip must be tracked all terrain vehicles.


    Fortunately, the city government has found several such cars, but these cars are not special medical vehicles. Most of them are only manned vehicles, and there is no way to bring the trailer type mobile operating room.


    Without Chen Xin''s help, the municipal government may consider only allowing the rescue team to go to the city first, and sending the mobile operating room to the city by rail or other means.


    Fortunately, Chen Xin offered to help with the chassis transformation of the vehicle, which solved the problem of the vehicle. At the same time, he also brought the whole set of mobile operating room with him.


    "Mr. Chen, thank you so much this time. You not only went with us in person, but also helped us to rebuild the car. You helped us so much. I really don''t know how to thank you." After Chen Xin helped to rebuild the vehicle, the leader of the rescue team was busy thanking him.


    "It''s nothing. I can do what I can, and I can help you solve these problems. You can arrive in Linshi earlier and help more people." Chen Xin said politely, but without much delay, he directly asked the team leader, "how many of you are going to Linshi this time? Is there any other equipment besides this cart? "


    "Because of the tight time and limited vehicles, we only transferred 15 medical staff and five drivers, a total of five vehicles, one surgical vehicle, one material transport vehicle and three people." As for the composition of the rescue team, the team leader did not need to hide from Chen Xin, and told him directly: "in addition, Mr. Chen, your car and a police car, there will be a team of special police comrades responsible for protecting the safety of the rescue team in the city."


    "When are you going to start?" Chen Xin is still satisfied with the rescue force. After all, they are only the leading forces. When they enter the city to find out the situation, they provide some limited help.


    As for more rescue forces, the municipal government is still organizing and coordinating, and will arrive in Lincheng after them."At present, there are still some materials that are not in place. We can start when everything is ready." The captain took a look at his watch and estimated the time before he said to Chen Xin, "if there is no problem, you can start early tomorrow. Mr. Chen, you can go back to have a good rest and keep your spirits. We can leave early tomorrow or arrive in Linshi early."


    Hearing what the captain said, Chen Xin nodded and agreed: "OK, I''ll come back tomorrow morning. It''s better to leave early. It''s not easy to go to Linshi. I used to walk this section when I went from this city to Anhui Province. At that time, the snow was not as thick as it is now. It took me a long time to walk from this city to Linshi. Now it''s more difficult to walk. You should be prepared. "


    "It takes more than half a day to walk tens of kilometers. Is the road so difficult?" The team leader was a little surprised. He thought that even if it was snowy, it would be several hours before the city could get to Linshi. But he didn''t expect that Chen Xin would spend most of the day talking.


    "All roads are covered with one or two meters of snow. If there is no road to find, it''s very fast to walk about five to eight kilometers in an hour on such thick snow." Recalling his last experience, Chen Xin also felt helpless. It''s not easy to walk these dozens of kilometers.


    Hearing Chen Xin say so, the team leader nodded thoughtfully. At the same time, he planned to hold a meeting with the members of the rescue team in the evening to prepare everyone.

 Chapter 338

    A convoy of seven cars left the city in the early morning and headed for Linshi under the leadership of Chen Xin.


    Chen Xin''s speed is not fast. In fact, after he got out of the city, he had slowed down his speed and let his car go at the speed of 10kms.


    It''s not that it can''t be faster, but Chen Xin needs to take care of the six cars behind him to keep up with them and keep driving safely.


    The road conditions leading to Linshi are much worse than when Chen Xin drove back to his hometown last time. The snow has become thicker and deeper, and at the same time, the surface has been buried more seriously.


    Don''t think that the snow is deep enough and it''s easy to walk on a flat road. In this kind of dark night, without reference object, it''s easy for people to deviate and get lost.


    Even if Chen Xin has radar positioning and UAV detection, in this case, he can ensure that he does not deviate, but also ensure that the six cars behind him do not deviate.


    For Chen Xin, it''s also a brand new experience. After all, he hasn''t been the leader of a team.


    Keeping in touch with the other six cars through the radio station, Chen Xin personally drives the car forward while also paying attention to the situation of the team at any time.


    Fortunately, the distance is not far, the drivers of the team are all old drivers, and the police car of the special police force is used as the tail car to hold the line. Generally speaking, there is no problem.


    In the car, Chen Xin only planned to take Han Ping with him, but Mo Qingyan and Qin LAN finally got into the car and insisted on going with him.


    Mo Qingyan''s reason is very good, because she received the distress signal first. The "drilling expert" in Linshi is also her client and friend. At this time, she should go with her in both emotion and reason.


    Qin Lan said that she wanted to protect Chen Xin, and Han Ping had to work as a part-time driver, which could not protect Chen Xin''s safety.


    In the face of their insistence, although Chen Xin felt baffled and helpless, he finally agreed to let them both follow.


    After all, Qin LAN has the power armor Chen Xin has made for her, and Mo Qingyan has a suit of exoskeleton protective clothing. When she gets to Linshi, even if it''s just a labor force to help her move things, many people will help her.


    As for the troubles and problems caused by the two women getting on the bus


    First of all, Qin LAN and Mo Qingyan are not unreasonable. Even if they have any problems, they will not really make trouble.


    Moreover, even if something really happened, Chen Xin felt that he should be able to deal with the problem well.


    In a word, with the worry of Linshi, the seven cars of this line are marching towards Linshi in the dark, hoping to help them.


    - -


    "the front radar detection shows that the snow is soft, the rear car should pay attention to avoid, keep close to the front car, and pay attention to follow the rut of the front car." Chen Xin, holding a walkie talkie, is reporting the road conditions to the vehicles in the rear.


    After his last upgrade and calibration, the radar system can now detect the condition of snow and the condition of snow, and the UAV has also added the function of acoustic detection. The combination of the two makes Chen Xin have a very clear grasp of the road conditions.


    Controlling the steering wheel allows the vehicle to avoid the road section where the snow is soft and may collapse, and drive along the place where it is more solid. Chen Xin also slows down the speed, so that the car behind can react and follow his ruts.


    Although this section of the road looks very flat, through the detection of UAV and radar, Chen Xin knows that the place he is bypassing is actually a slope below.


    They should be in the same position as the highway in the past, but the highway is now buried under more than two meters of snow.


    Not only that, this expressway is actually a supported elevated line. Chen Xin''s route is the location of the expressway in the past, because the support of the expressway bridge below is stable and solid.


    But the snow on both sides of his route is much softer, because the snow is empty, without any support, it is pure snow.


    Walking in this section of the road, even if Chen Xin has enough confidence in his car, he also moves forward cautiously.


    Last time he passed here, he could still see the expressway bridge. Although the bridge deck was seriously damaged and many places collapsed, which made him go back for a while, at least he could walk and see the traces of the expressway in the past.


    However, now even this trace can not be seen, everything is just a flat, only slightly undulating snow.


    Qin LAN and Mo Qingyan are both sitting in the back seat of the cab at the moment. Looking at the snow plain illuminated by the car lights in front of them, they seem to be a little distracted.


    "Ah Xin, the last time you went back to your hometown, did you take the same road?" Qin Lan thought of Chen Xin''s return to his hometown last time, and suddenly asked him about it.


    Chen Xin, holding the steering wheel, nodded and replied: "last time I went from here too. At that time, I could still see the crater on the road. The highway and bridge were smashed and collapsed, so I had to take the national highway.""Did this place use to be a highway? Isn''t that the way we used to go Mo Qingyan recalled that she used to organize friends to go to Linshi for outdoor activities. She was very surprised when she walked this way: "but I remember that highway should be very high, right? It''s at least seven or eight meters from the ground. Are they all buried? "


    For this, Chen Xin was also surprised, but he nodded and said: "it should be, at least the situation shown on the radar, the original highway bridge is under us."


    "This is really..." For a moment, Mo Qingyan was speechless and didn''t know what to say.


    Looking at Mo Qingyan in the rearview mirror, Chen Xin shakes his head. He seems to have some emotion about her performance, so he says: "in fact, it''s not impossible for a snowstorm like before to cause this situation. You know, it''s a snowstorm with a wind speed of - 70 ¡æ reaching level 12, which is enough to freeze and destroy everything."


    "But it''s not enough to say that this kind of snow is more than ten meters, is it?" Mo Qingyan thought in mind that the distance between the snow surface and the original ground was still unable to make complaints about it.


    Chen Xin just had no choice but to smile: "because of the obstruction of building debris in the city, the snow in most parts of the city is only more than two meters thick. In better places, it may be only more than one meter, and the serious situation is only five or six meters. But in the suburbs, where there is no vegetation now, the Blizzard has no obstacles, and can carry a large number of snowflakes and form more than a dozen The snow behind the meter is no exaggeration

 Chapter 339

    There was no accident on the way to Linshi. After all, it was only a few tens of kilometers. Chen Xin''s car had complete detection means and had a good grasp of the road conditions. The probability of occurrence was not very high.


    However, when they arrived at Linshi, they were surprised by the state of Linshi.


    The terrain near the city is a typical valley terrain between the two mountains. The other end of the valley is facing the Yangtze River, and there is a lake between the city and the Yangtze River.


    That lake is a relic of Guyun Mengze, which has not been connected with the Yangtze River and Dongting Lake for a long time. The crab produced in it was a famous product of the city before the disaster. In the crab eating season every year, a large number of crabs consumed by the city come from here.


    However, not to mention that the whole lake has been frozen into ice, and no more delicious crabs can be eaten. The water level of the Yangtze River has also surged due to the seawater flooding caused by the tsunami, flooding the lake. "Coastline" once approached the urban area near the city.


    In fact, it''s not just the city. Although the city is located in the central part of Yanguo, the sea water flooding caused by the tsunami is at the end of its rope when it arrives at Dongting Lake, but it still makes the water level of Dongting Lake rise a lot, and most of the areas along the lake in the city suffer from flooding.


    If the city is not hilly terrain, the terrain is relatively high, I am afraid most parts of the city will be soaked in water.


    On the other hand, the city side is worse than the city side. After the water level rises and freezes, the side of the city facing the Yangtze River becomes unobstructed.


    When a snowstorm comes, the valley terrain with two mountains and one ditch, coupled with the flat ice surface, makes the whole city a wind pocket. Because of the mountain trend, the wind speed of the snowstorm blowing towards the city is faster and the snowstorm is more concentrated.


    Originally, due to the abundant water vapor near the Yangtze River and lakes, they all turned into ice and snow under low temperature, and were carried by blizzards to Linshi.


    Because of these factors, the whole city has been almost completely covered by snow.


    Most of the buildings in the city have been buried under the snow, and only a few of the higher buildings have their roofs exposed.


    After all, Linshi is only a county-level city. There are not many high-rise buildings in the urban area. Under the blizzard, most of the buildings are engulfed by snow because of their insufficient height.


    But in the face of this situation, all of the rescue team have a sense of whether they are late or not.


    "Linshi Isn''t everyone buried under the snow? " In the walkie talkie, a female voice made such a question.


    She is a doctor of the rescue team. She signed up to save people. As a local, she also has some relatives and friends in the city.


    But now that the whole city is covered with snow, it''s hard for her to believe that there are still survivors in the city.


    Chen Xin naturally has the same worry, but relatively speaking, he is not so pessimistic.


    "The situation should not be so bad. In the communication with the urban area before Linshi, Linshi did not indicate that there was a big problem. It is impossible to say that the whole city was gone in such a short time before we came here." Chen Xin spoke calmly, and took the initiative to propose a response plan: "the UAV and radar on my car can detect life signals. Let''s find a place to stop the car first, and carefully search for the traces of survivors."


    "I agree with Chen Xin. Let''s find a place to stop the car and get to know the situation." As the leader of the rescue team, the captain chose to support Chen Xin at this time.


    In the process, Chen Xin also released his UAV and switched the radar to the life signal search mode, hoping to find the traces of survivors.


    As for the other vehicles, the team leader is trying to contact the municipal government of Linshi to send them the message that the rescue team has arrived. However, everyone on the other vehicles is worried. They are still worried about the situation of Linshi and whether they are really late. At the same time, they are actively doing all kinds of preparatory work.


    After all, if there are still survivors in the city, once they are found, the rescue team will immediately put into the rescue operation.


    Among them, Chen Xin''s radar and UAV were the first to find the survivors.


    "A heat source signal was found nearby. It should be the vent of the shelter." The display of heat sources on the radar is still very obvious. Chen Xin just raised the UAV to high altitude, and then switched to infrared mode to find several obvious heat sources.


    Chen Xin doesn''t know exactly what''s going on under the snow, but judging from the number and distribution of heat sources, he thinks this should be the main refuge in Linshi.


    When they learned that the shelter was still in operation, the people on several vehicles were relieved. This is very good news. At least they didn''t make a trip in vain, and Linshi didn''t become an empty city.


    In addition to Chen Xin''s news here, the team leader also contacted the municipal government and informed them of the arrival of the rescue team.The municipal government is very excited and happy for the rescue team to arrive. Although the number of rescue teams arriving is not large and the help they can provide is limited, it at least means that the urban area has spare power to help them at this time. The arrival of the rescue team has injected hope into the cold darkness.


    According to the information obtained after the team leader contacted the municipal government, the rescue team stopped at a place that should have been a square in the city center.


    It was supposed to be a commercial square. This is the biggest refuge in Lincheng.


    There is only one large shelter and three medium-sized shelters in the city. The total number of survivors after the disaster is only over 100000.


    In the previous blizzard, a medium-sized shelter was buried by the blizzard, and now it has been abandoned. The total population still living in the city may have been less than 100000.


    Knowing the situation, after all the cars were parked, the team leader found Chen Xin, along with the special police in charge of leading the team and a doctor.


    "I''m sorry, Chen Xin. You''re the only one with a lot of space, so I''d like to borrow your place for a meeting." The team leader said sorry to Chen Xin, and then sat down with other people under Chen Xin''s greeting and talked about the business: "now we have arrived at Linshi, and the Linshi municipal government has just informed us about the relevant situation. Now the situation in Linshi is very bad. We must discuss how the rescue team should carry out the rescue work."

 Chapter 340

    After some discussion, the rescue team did not directly enter the refuge near the city to carry out the rescue.


    On the one hand, the internal situation of the shelters near the city is unclear, and there will be some security risks if they enter rashly. On the other hand, there are too many patients in need of rescue in the shelters. Without a reasonable classification, it is very likely that they will not be able to play the greatest role if they directly invest the rescue forces.


    For a simple example, if the rescue team entered a shelter to treat the patient, who would be the first to receive treatment?


    Some people may think that the serious patients should be treated first, but in fact, on the contrary, in this case, the light patients who still have the strength to come to the rescue team will be the first to get treatment.


    Because the serious patients are too sick to compete with the mild patients to get the chance of treatment.


    As for asking the rescue team to look for serious patients inside the shelter and treat them It can only be said that this idea is very beautiful. If the number of patients in the shelter does not exceed a certain limit, it is feasible. After all, everyone knows the priority. If the critically ill are treated first, more people can survive.


    However, when the number of patients breaks through a limit, especially when some people in the shelter have died and most of them have been ill, everyone will first want to survive, rather than think that they can stick to it and give priority to those who need it more.


    In the case of no survival pressure, people may be willing to help others. When there is a certain survival pressure, there are still people who are willing to help more needy people without endangering themselves.


    But in the face of life and death, the vast majority of people first consider how to survive, and even seize the opportunity for others to survive, rather than to help others.


    So for the rescue team, if you want to rescue effectively, go deep into the shelter to treat the patients, the effect may not be good.


    Of course, that doesn''t mean the rescue team will do nothing.


    Although most of the goods and materials they brought were medicine and medical materials, they also brought a set of medical tents, which can be deployed in a suitable place to serve as a temporary hospital.


    In fact, after discussion, the rescue team did the same.


    They surrounded seven cars into a circle, then put up the medical tent they brought with them in the circle and built a temporary medical station.


    The whole medical station looks a bit like the shape of an M. two tents are put together to form a horizontal line, and the other six tents are joined together to form three vertical lines.


    The two horizontal tents are the clinic, while the six vertical tents are the preparation ward. All the tents are connected by closed channels, and a windproof compartment is specially made at the entrance to protect the heat in the tent.


    The tent itself is also a special cold proof tent, and the temperature is acceptable when the heater is set inside.


    As for the power supply of the tent, the rescue team originally planned to use a generator to supply power, but Chen Xin connected the power line of the tent to his car, and used the isotope thermoelectric battery to supply power, which was much easier than using a generator.


    After the installation of the medical equipment in the tent, the temporary medical station of the rescue team officially began to operate.


    According to the plan discussed before, five drivers of the rescue team and two special police officers will enter the shelter near the medical station with the assistance of the staff sent by the municipal government, and transport the critically ill patients out of the shelter for treatment.


    At the same time, the medical station will also be open to ordinary patients for necessary treatment to help them recover.


    However, unlike severe patients who will be admitted to the ward, mild patients will not stay in the medical station after being treated.


    Before departure, the city government had already equipped the rescue team with protective clothing, and the special police in charge of safety were also equipped with exoskeletons, which can be said to be very safe.


    Soon after the medical station started working, survivors from the shelter under the snow came to see a doctor.


    Considering the reception capacity of the medical station, and in order to avoid disorder, only about 50 mild patients come for treatment at a time. After the doctors of the rescue team have treated the 50 patients, they will return to the shelter, and then new patients will come to see the doctor.


    Under the command and coordination of the staff of the municipal government, the work was carried out in an orderly way.


    However, most of these patients have varying degrees of frostbite, and some of them need amputation.


    This undoubtedly makes many people reluctant. After all, no one wants to be short of arms and legs. Even if his hands and feet have begun to turn black and necrotic, it is likely to endanger his life if he does not amputate.


    In the face of this situation, in addition to explaining the situation and persuading patients to accept amputation as much as possible, the rescue team has no good way.


    Although it''s not to say that the amputation can''t be forced, the doctors of the rescue team still hope to persuade the patients to accept the operation voluntarily, even though they don''t have much time to persuade the patients.Fortunately, although most people are reluctant to do so, they will basically choose to live among the options of death without amputation and life with amputation.


    But there are still some other people who think that the doctor is harming him and want to cut off his hands and feet so that he can become disabled from a healthy person.


    If he just refuses to cooperate with the doctor''s treatment with such an idea, it''s just his own death, but very few people still want to fight against the doctor.


    Although the severe frostbite makes people who need amputation have little ability to move, even if they want to fight with doctors, they will be suppressed by the special police in an instant, but it still has a very bad impact.


    For the survivors in the city, they are in a state of stress. They have survived the blizzard in the cold, but they can only drag the sick body to die. Now it is not easy to have doctors to treat them, but there are still people making trouble. It is easy to frighten these survivors.


    Once people are stimulated and frightened in a state of stress, it is easy to act excessively, and even lead to riots.


    Fortunately, the special police in charge of maintaining order are fully armed, and they are also wearing exoskeleton protective clothing specially made into police colors with police lights. They are still strong enough in deterrence to maintain order.


    As for those who want to make trouble under the control of the police, they will be forced to take compulsory measures.


    Although they will not be given up treatment, they will obviously have to clear their minds and be responsible for their mistakes.

 Chapter 341

    The situation in the city is really too bad. After the rescue team set up the ambulance station, only a few hours later, the six tent wards originally prepared by the rescue team had been filled with all kinds of serious patients.


    The first aid tents brought by the rescue team are not small. Eight beds can be set up in one tent, and six tents can be crowded to accommodate 50-60 patients.


    Although the number is not very large, it is not easy for a temporary ambulance station to provide so many beds.


    You know, even the clinics in the shelters can provide only so many beds.


    But in a few hours, the beds in the six tents were quickly filled with all kinds of critically ill patients and patients who had just undergone amputation.


    At the same time, a steady stream of patients are being sent here.


    In the face of this situation, a nurse found the team leader who was discussing with Chen Xin and reported to him that the ward was full: "team leader, now all the beds are full, but there are still patients who have been sent. We can''t accept them any more!"


    Hearing what the nurse said, both Chen Xin and the team leader were shocked, but neither of them showed panic.


    After the team leader said that he knew to let her go back to work, he said to Chen Xin, "it can''t go on like this. It''s only a few hours! I didn''t expect that the situation in the city was so serious that our rescue force was just a drop in the bucket!


    We must find a way to expand the number of patients in the first aid station, otherwise our rescue will not play any role at all, but will drag us down! "


    "Let two material carriers follow my car and go back to the city for help." For this situation, Chen Xin did not expect. At this time, the only way he could think of was to send someone back to ask for help and let more materials be transported from the city.


    However, in addition to asking for help, Chen Xin felt that they could not just wait. After thinking about it, he said to the team leader, "in addition to asking for help, we need to think of other ways."


    "I can''t think of any other way! The tent is only that big. No matter how much it is put in, it can be put in at most. Twelve people will die. " The team leader seemed to be very experienced in this kind of thing. He shook his head, obviously he couldn''t continue to add people to the ward: "the ward is not like a settlement. The settlement can set up a double bed, and it doesn''t matter if there are more people in the tent. You can''t set up patients in the ward!"


    "Can you find a way for the workers in the city to make room for the patients in the shelter?" Chen Xin thought about it and thought that this method should be feasible.


    Most of the patients placed in the ambulance station are caused by low temperature environment. All kinds of diseases are aggravated due to long-term lack of treatment. After the doctor''s treatment, they only need to have a good rest and cooperate with the treatment, and can gradually recover.


    However, some of these patients need medical equipment for support, and they can only continue to be placed in the ward of the ambulance station.


    But the other part does not need medical equipment support, the situation is slightly better, only need bed rest, can be transferred to other places for resettlement.


    As for the other part of patients with amputation due to frostbite, they can actually be transferred to other places for resettlement after they have passed the dangerous period of operation.


    What most people cut off is not the whole leg or arm, but fingers or toes. In fact, they don''t need a bed in the ambulance station.


    Although it seems a little inhuman to do so, it is worth doing so considering that if we can transfer this part of patients from the ambulance station, we can make the ambulance station treat other patients more effectively.


    The team leader obviously took this into consideration. After thinking it over, he nodded his head and agreed with Chen Xin''s suggestion: "then I''ll go to the staff of the city to coordinate, and I can really transfer some patients with moderate illness out."


    In fact, this is the same as the establishment of special hospitals and shelter hospitals in the event of major outbreaks. Special hospitals are used to treat patients with moderate to severe and critical illness, while patients with mild illness can continue to receive treatment in shelter hospitals.


    In this way, medical resources can be effectively utilized and more patients can be treated.


    But now the rescue station of the rescue team can only treat the patients with severe and critical illness. The patients with mild illness will return to the refuge after treatment, while the patients with moderate illness will be transferred to the designated ward for follow-up treatment.


    After all, most of the patients here are not infectious, and most of the patients with mild and moderate diseases can recover naturally as long as they are treated, and they do not need to be hospitalized.


    See the team leader to busy with the city staff to coordinate this matter, Chen Xin also turned back to his car.


    Only Han Ping is staring at the car radar in case of any emergency. Qin LAN and Mo Qingyan go to "drilling expert" together.


    Although Qin LAN and Mo Qingyan came to Linshi with Chen Xin and the rescue team, what the rescue team needs most now is professional medical personnel. Qin LAN and Mo Qingyan can''t help much, so they went to "drilling talent" and other friends of Linshi to see their situation.If they need help, Qin LAN and Mo Qingyan can also help depending on the situation.


    As for their safety, Chen Xin is not worried at all, because Qin LAN is wearing her power armor, and Mo Qingyan also borrows Chen Xin''s suit.


    When Chen Xin first made the power armor, considering the comfort of the power armor, he designed its internal size to be self-adjusting. As long as the difference between two people''s figures is not particularly big, they can wear it.


    So Chen Xin doesn''t mind lending her power armor to Mo Qingyan to provide her with a security guarantee.


    When they come to the cab, Chen Xin and Han Ping say hello, and then they call up the radar monitoring screen from the console. They see the red dots representing Qin LAN and Mo Qingyan. After thinking for a moment, they launch the reconnaissance UAV on the car and fly towards their positions.


    Although he knew they were safe, Chen Xin was still worried about their situation.


    The UAV flies very fast, but before the UAV approaches Mo Qingyan and Qin LAN, it unexpectedly scans a heat source signal first.


    Chen Xin was somewhat surprised to find that the heat source signal did not come from the official refuge near the city, but from a private refuge.


    Chen Xin was quite surprised. In Linshi, in addition to the "drilling expert", several other group friends also built a private shelter. Now that they have found a private shelter, Chen Xin can''t help but care whose shelter it is, so he controls the UAV to fly towards the heat source.

 Chapter 342

    Under the snow, Bao Zhen is trying to dig an upward passage with his hoe.


    At his side, a German Shepherd is also struggling to help dig the snow, but a dog''s ability is limited. When Bao Zhen is struggling to dig up the passage, the dog is just digging a pit for him.


    "OK, jackal, I know you want to help. Go to the side and have a rest. I''ll do it myself." Bao Zhen looked at his dog planed for a long time, but he didn''t find anything famous. On the contrary, he shivered with cold and immediately let the dog go back to rest.


    This drummon, named hulang, was very obedient. Although he did run to one side and lay down to have a rest, he kept looking at his master and didn''t go far.


    This is the 37th day that Bao Zhen was trapped underground. Because of the low terrain of his shelter and the structural problems, the entrance of his shelter was completely covered with snow when the snowstorm was raging, and it was still very deep.


    If the ventilation pipe of the shelter had not been connected from the inside of the building to the top of the building, and the ventilation pipe had not been buried, I''m afraid Bao Zhen would have hung up by now.


    Although the ventilation pipe can still be used, because there is a planting box to provide oxygen in the room, it won''t suffocate. However, three and a half floors of the four story building he lives in has been buried by snow. If Bao Zhen doesn''t dig out, he will be buried underground all the time.


    Although Bao Zhen is well prepared before the disaster, and he has a whole set of living facilities built by himself, which is enough for him to eat and drink for one person and one dog, he has consumed almost all the fuel in his reserve. He must find a way to replenish the fuel, otherwise he will not be able to sustain for a few days if he is trapped underground without fuel.


    And no one would like to be buried in the snow, even if they will not die. This is no different from the prison life. No one is willing to live, especially if you are the only one.


    Just as Bao Zhen was trying to dig his way to survive, the UAV controlled by Chen Xin flew to his place and found Bao Zhen along the heat from the vent on the roof.


    Only through the UAV observation, Chen Xin looked at the buildings almost completely buried by snow, and found no place to enter the buildings for a long time.


    Although there are still some places on the top of the building that are not completely covered by snow, when you enter the room along the broken window of the top floor, you will find that the room has been filled with snow in the previous blizzard. Although there are still some gaps, it is impossible to enter the building from the top floor.


    However, although unable to enter the building, Chen Xin still found Bao Zhen, who was trying to dig up underground, through the life detection equipment of the UAV.


    However, I don''t know if Bao Zhen''s communication equipment has been damaged. Chen Xin tried to make a call with a radio station, but he didn''t receive any reply.


    In the face of this situation, Chen Xin decided to save people after thinking about it.


    Although his power armor was worn away by Mo Qingyan, Chen Xin still has a suit of exoskeleton protective clothing, which is enough to meet his needs for going out.


    Chen Xin Let Han Ping continue to stay in the car staring at the radar, and he called two temporary city staff together, toward the position where he found Bao Zhen. After the blizzard subsided,


    also received a number of protective clothing and exoskeletons. Although the number was not large, the two staff members who came with Chen Xin may have a protective suit on their work because of their work needs. One of them, armed with shovel, had even an exoskeleton.


    The exoskeleton produced by the state is different from the version provided by Chen Xin. It is obvious that some of Yanguo''s own technologies are applied, rather than just copying according to the drawings provided by Chen Xin.


    And the exoskeletons produced by the state are also divided into civilian, police and military exoskeletons that Chen Xin knows have this model, but has never seen.


    This staff member is obviously a civilian type, and only has some simple power functions. Compared with the original version of Chen Xin''s body, his output is lower, and it should also be simpler. There is no protective armor of police exoskeleton on the rescue team''s special police.


    But even so, such a civilian exoskeleton for ordinary staff is completely enough.


    At least when we went to Bao Zhen''s place with Chen Xin, the staff without exoskeleton had difficulty walking in the snow, but the staff with exoskeleton could walk freely and help their companions.


    After all, Linshi is only a prefecture level city with a long and narrow urban distribution. The place where Baozhen is located is not far from the ambulance station.


    "Mr. Chen, is the survivor under this building?" The staff looked at the top floor of the building, which was not covered by snow. They didn''t know what to do.


    "Yes, the life signal detected by the UAV is just below here. He should also be actively helping himself, digging up the channel. We just need to dig down." Chen Xin introduced the situation to the two staff members, and contacted Han Ping through the communicator on his exoskeleton, asking him to transfer the pictures taken by the UAV to him.Although two staff members felt that three of them might not be able to dig out the people buried below, they did not refuse to take the blame. They picked up their shovel and were ready to help.


    Chen Xin relied on the projection of the helmet on his face mask, and found the position, then shovel the first spade.


    though only three people, the tools were only three shovel, but with the help of two exoskeletons, three people quickly dug a big pit on the ground.


    "Don''t dig so vertically. Let''s unload and dig a spiral channel, or we''ll have to find a way to come up later." Chen Xin saw that the pit was already a little deep, so he told the staff on one side and adjusted the direction of digging downward.


    Although the workload of unloading and digging a spiral passage is several times larger, the two staff members also know that it is necessary, so they can only cooperate with Chen Xin and continue to dig downward.


    The people above are digging down, and naturally the people below are not idle. Bao Zhen is also trying to dig up, and he has been digging up spirally from the beginning. After all, if he dug up vertically, he could not dig himself out of the ground.


    But Bao Zhen, who is still working hard to find his own way to survive, doesn''t know that someone has come to save him over his head.


    Now the problem is that the snow is about ten meters deep. When the two sides dig together, the speed of digging on the ground is five times that of underground. Half an hour above the ground, one meter can be dug down. How long can we dig through this section of snow?

 Chapter 343

    When the snow on the top of him collapsed and covered his face, and even two people fell down, he was stunned.


    However, when he shook off the snow and stood up, he stopped the wolf barking at the two figures who were also sitting up. He asked the two men happily, "are you here to save me?"


    Chen Xin patted the snow on his body and looked at the figure in front of him. Although he didn''t recognize that this man was Bao Zhen, he nodded and said, "yes, we are here to save you."


    To tell the truth, Chen Xin did not expect the collapse, which made both sides very embarrassed, but did not cause serious consequences, and successfully dug out the trapped people. The result is very ideal.


    After successfully opening up the upward channel, Bao Zhen was not in a hurry to go out for a while. Instead, he warmly invited Chen Xin and two staff members to his refuge for a rest.


    Chen Xin and two staff members didn''t refuse. After all, they dug for several hours. Even with the help of exoskeleton, they really worked hard and needed a rest.


    Four people go back to Bao Zhen''s shelter. After he takes off the headgear, Chen Xin recognizes him. Bao Zhen also recognizes Chen Xin who takes off his helmet.


    "The writer? How did you get to the market? Are you an exoskeleton? Where are you from? How cool Bao Zhen is actually a few years younger than Chen Xin. After recognizing Chen Xin, he simply says hello and focuses on Chen Xin''s exoskeleton.


    "Daren sent me a distress signal, saying that you are in a bad situation near the city and are going to be unable to hold on. Let me find a way to save people. Just as the city is going to send a rescue team, I will come with you." Chen Xin was also surprised to meet Bao Zhen. He was a little happy and explained to him: "as for this, exoskeleton is the material recently distributed by the state. I got it because I came with the rescue team. It''s you. How''s it going? "


    After listening to Chen Xin''s explanation, Bao Zhen''s face was full of envy. He asked the three to sit down and poured them a cup of hot water before he said, "I''m not in a good situation. Although food and water are still enough, there are not many fuel and living materials left.


    Before the blizzard, the antenna I installed outside was damaged, so my communication with the outside world was interrupted. Later, I was simply buried in the snow. These days, I heard that the wind was low outside from the vent, so I began to dig out, ready to dig a way out, and you hit me in the end. "


    "It sounds OK. At least you didn''t freeze to death or starve to death." Chen Xin listened to Bao Zhen''s explanation of his situation during this period and made a very pertinent evaluation.


    When Bao Zhen heard this, he immediately said, "what are you talking about! How can I be frozen to death or starved to death? Curse me, don''t you


    Although the tone of dissatisfaction, but Bao Zhen is obviously joking, and did not take this too seriously.


    "No, you''re really OK. At least you have food and drink, and a dog with you. You''ve been buried in the snow for a month, but there''s nothing wrong. There''s no disease or disaster. It''s really better than most people." But Chen Xin explained it very seriously, obviously not as a joke.


    And the two staff members nodded together, also feel that Bao Zhen''s living condition is very good.


    This made Bao Zhen very surprised. He couldn''t help but ask Chen Xin, "I''ve been buried in the snow for more than a month, but it''s still good. What''s worse in other places?"


    "Because of the previous blizzard, a shelter in Linshi was completely buried by the snow, and many people died." Chen Xin''s expression is dignified, and his tone is also full of sigh: "there are still many people who need amputation because of cold injury and illness, but they can''t get timely treatment, leading to necrosis of hands and feet. The rescue team also came to support the city."


    Speaking of this, Chen Xin patted Bao Zhen on the shoulder and said to him, "brother, you are really lucky!"


    Bao Zhen was very surprised by Chen Xin''s situation in the city. He couldn''t believe it. But after confirming to the two staff members, she had to believe that she was really lucky, and the living conditions were really good.


    Although Bao Zhen is now facing some difficulties due to the shortage of fuel, he is not short of food and drink. He even grows some vegetables with a planter, raises some chickens and ducks, and has a dog and a fox as pets. The situation is much better than most people.


    Knowing the situation, Bao Zhen was a little more worried about the situation of Linshi and asked Chen Xin, "is there anything I can do for you?"


    "What we are short of now is doctors to treat patients. There is no shortage of other people. You''d better solve your own problems first." Chen Xin shook his head and declined Bao Zhen''s offer to help.


    In Chen Xin''s opinion, Bao Zhen''s own problems are still unsolved, and it doesn''t help much to ask him to help.


    Bao Zhen thought about it and thought it was true, so he didn''t insist on helping. He just asked Chen Xin, "can you help me get some diesel? My fuel reserves are almost bottoming out. If I don''t replenish it, the generator won''t work. It would be better if I could get some toilet paper and other daily necessities. "For Bao Zhen''s needs, Chen Xin can''t provide them at this time, but he looks at the two staff members who are with him. They are city staff. If you want to get the materials Bao Zhen wants, it''s obviously more appropriate to find them than Chen Xin.


    Being watched by Chen Xin, the two staff members didn''t refuse. These materials belong to the scope they can get, but they obviously can''t provide them to Bao Zhen for free, so they asked him, "we can get you what you want, but it''s not free."


    Bao Zhen understood that even before the disaster, the state would provide at most some emergency supplies, which should be exchanged with some supplies in his own hands.


    "I''ll trade my own chickens and ducks for you! Do you want chicken or duck? How about a 150L gasoline Bao Zhen thought about it and took out what he could exchange now.


    "150L is too much! We can get you 100L or 150L at most, and we can''t get it for you! " When the staff heard that Bao Zhen said that he could exchange chicken and duck, they immediately swallowed and talked with him about the price.


    Looking at their bargaining, Chen Xin didn''t interrupt. He just came to one side and teased Bao Zhenyang''s Fox and his dog.


    This is the first time Chen Xin has seen a large living animal since the disaster.

 Chapter 344

    Chen Xin did not stay with Bao Zhen for a long time. When he and two staff members agreed to exchange a chicken for 120L diesel, Chen Xin and the staff left.


    Bao Zhen sent Chen Xin out of the shelter, and he continued to dig the tunnel with his shovel. Though the tunnel had been opened, if Bao Zhen wanted to use it, he needed some reinforcement and amendment.


    Chen Xinze and the staff returned to the ambulance station together.


    "Chen Xin, are you back? I''m looking for you Seeing Chen Xin coming back, the team leader immediately found him and said to him, "the car back to the city for help is ready. You need your car to drive, but your driver said you didn''t come back and didn''t dare to promise. You see, you should tell him quickly that the car for help is ready to go."


    When Chen Xin heard what the captain said, he immediately wanted to pat his head. When he went out just now, he forgot to tell Han Ping about it.


    So Chen Xin hurried back to his car, found Han Ping, told him about it, and asked him to drive back to the city with other cars asking for help.


    Han Ping didn''t refuse. In fact, he was ready to start when the team leader came to him, but Chen Xin wasn''t there, so he didn''t dare to agree to it.


    Now that Chen Xin is back, he is sure to go back to the city to ask for help. Naturally, without saying a word, Han Ping drives his car and takes the other cars on the road.


    It''s just a pleasure to promise to go back to the city for help, but when the car drives away, Chen Xin is a bit embarrassed about where he sleeps at night.


    After all, he, Qin LAN and Mo Qingyan all sleep in the car. Now that the car is gone, the bed they sleep in is gone, so they have to find another place to sleep at night.


    However, it''s not too difficult. The other cars from the rescue team can also sleep, but the conditions are not as good as Chen Xin''s, and it''s just a matter of making do for one night. When Han Ping drives back, it''s OK.


    Qin LAN and Mo Qingyan are two girls. They are still inconvenient and need extra care.


    So Chen Xin didn''t care much about it either. After talking to the team leader and asking him to help arrange the accommodation for the night, he went into the tent of the ambulance station to see what he could help.


    There are still a lot of patients in front of doctors in the emergency station. Several special police officers wearing exoskeletons are standing in the tent to maintain order, flashing red and blue lights peculiar to the police lights.


    Compared with what Chen Xin had seen before, the situation now seems to be much better. At least the patients who come to see the doctor are basically in a stable mood, and they look forward to seeing the doctor.


    Even if there is a need for surgery or amputation, but also basically in the doctor''s persuasion can calmly accept.


    This kind of change surprised Chen Xin a little, but I can understand it when I think about it. After all, it''s only a few people who make trouble. Most people are willing to let themselves live instead of making trouble out of nothing.


    Chen Xin didn''t know anything about medical skills, so he couldn''t help these doctors, so he went through the reception area and came to the back ward.


    The ward was a little empty than before. At least when Chen Xin came in, he saw the empty bed. It was much better than before.


    "Head nurse, is there anything I can do for you?" Chen Xin finds the head nurse in the ward and sees that she is doing an examination for a patient. When she is finished, Chen Xin asks her if she can help.


    The head nurse was so busy that she was a little dizzy. Chen Xin''s appearance made her stunned for a moment, but she thought about it very quickly and said to Chen Xin, "can you go and help move the oxygen bottle that you brought in the car? I''m all girls. They can''t move that one. Several drivers are driving back. I''m worried about no one to help me! "


    Chen Xin heard the head nurse say so, Chen Xin just asked her: "where is the oxygen bottle?"


    The head nurse quickly called a little nurse and asked her to take Chen Xin to move the oxygen cylinder.


    He left the ward with the little nurse and came to a car around. The little nurse opened the door and pointed to the blue oxygen bottle on the car and said to Chen Xin, "the oxygen bottle is on the car. You can help move two of them down and send them to the ward over there."


    Chen Xin nodded and asked the little nurse to stand aside. Then he jumped into the car, lifted a one person high oxygen cylinder, rolled from the car to the door, and with the help of the little nurse, he carefully inserted it in the snow.


    This kind of oxygen bottle is not light, and because it is filled with liquid oxygen, it can not be placed horizontally, so it can only be inserted in the snow.


    After Chen Xin moved another oxygen bottle down, he asked the little nurse, "didn''t you have an exoskeleton when you came here? Why doesn''t it work? "


    "We don''t know how to use it. Just a few drivers trained before they came here. They were afraid that they didn''t dare to use it if something happened." The little nurse explained to Chen Xin and said, "thank you for your help. If it wasn''t for your help, we would be really hard to handle these oxygen bottles."


    An oxygen cylinder is very heavy. In general, if you want to move it, you should put it on the ground and roll it after tilting. In this way, you can easily push it. However, if you want to move it, it is difficult for two adults to move the full oxygen cylinder.Fortunately for Chen Xin, with the help of exoskeleton, the 70 kg oxygen bottle can still be lifted.


    Holding an oxygen bottle in his arms, Chen Xin said to the little nurse, "let''s move it twice. It''s not easy to move the two together. Is it to the tent in front of us?"


    "Yes, just move there. Thank you very much." When the little nurse saw Chen Xin holding up the oxygen bottle easily, she could not help feeling envious. After thinking for a while, she asked Chen Xin, "can you teach me how to use the exoskeleton?"


    "Of course, it''s not complicated to use. You can learn it quickly. If you can use it yourself, it''s much more convenient." Chen Xin readily agreed to the little nurse''s request.


    They moved the oxygen bottle to the ward. After putting it away, Chen Xin didn''t leave. Instead, he followed the little nurse to get busy in the ward.


    There are a lot of things in the ward. New patients need to arrange beds, patients who have finished surgery need to carry beds, and medical instruments need to be carried and intervened


    Just relying on the strength of a few nurses in the ward, we can''t be busy at all. Even with Chen Xin''s help, everyone is busy and has no leisure.


    For these little nurses, they just took a few hours'' bus from the city in the morning to the city. In the afternoon, they immediately put themselves into the work and worked hard for most of the day.


    Until dinner in the evening, most of the patients have been settled down, so we can have a little leisure and have a rest.


    But at this time, the former nurse found Chen Xin and planned to use this spare time to learn how to use the exoskeleton.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 345

    "Exoskeleton is a kind of power assisted mechanism. It''s not troublesome to use, because it is used to assist you. You don''t need to control it. In the process of use, you just need to adapt to the power provided by it." She helped the little nurse put a set of exoskeletons on her protective clothing. Chen Xin instructed the little nurse how to adapt to the exoskeletons.


    The little nurse who put on the exoskeleton for the first time was a little nervous. The fatigue of working all day also made her eyelids fight. It was difficult to concentrate her energy, but she still listened to Chen Xin''s explanation and tried to learn how to use the exoskeleton.


    Chen Xin saw the little nurse''s nervousness. He just laughed and calmed the little nurse''s mood. He took out a toolbox that had been prepared for a long time and said to her, "the exoskeleton itself plays a role of support and assistance. In short, it can make it easier for you to pick up heavy things.


    Take the box in my hand for example. Normally, it may take some effort to pick it up. I think it''s a little heavy, but if you use the exoskeleton, you will feel very easy to pick it up. "


    With that, Chen Xin motioned to the nurse to raise her arm, and then handed her toolbox to her.


    When the little nurse took over the toolbox, she thought it would be a little heavy at the beginning, but when the toolbox was handed to her hand, she felt that she could really pick up the toolbox easily, because she obviously felt that the exoskeleton she was wearing provided a borrowing point, which made her hand seem to have extra support.


    "It''s amazing. I feel as if someone is holding my hand here!" The little nurse excitedly described her feelings to Chen Xin, which she had never experienced before, which made her feel very novel.


    Chen Xin nodded with a smile and explained to the little nurse, "this is the support and power function of exoskeleton. It provides you with a new support point, and it can also provide certain assistance. This toolbox is not too heavy, and you may not feel it obviously. If it is the oxygen bottle before, you can obviously feel the borrowed power. ¡±


    hearing what Chen Xin said, the little nurse couldn''t help but turn her eyes to the oxygen bottle placed on one side.


    Chen Xin moved it in the afternoon. Because it was not used directly, it was put beside it. Chen Xin''s words made the little nurse eager to try, and wanted to experience what he said about borrowing.


    Chen Xin sees this, also did not obstruct, only signals the small nurse to be careful, simultaneously oneself also helped the oxygen bottle in the side, avoided her because of the improper operation and the accident.


    "When carrying heavy objects with exoskeleton, remember not to use too much force, because the exoskeleton itself is force feedback. The greater the force you use, the greater the force provided by the exoskeleton. Although the civilian version of the exoskeleton you use will not produce much force, it is not as if you throw out the oxygen cylinder, but you should also be careful to flash to your waist." Chen Xin said that she also patted the little nurse on the back to indicate her attention to the back force: "this is also the most common problem in the use of exoskeleton. At the beginning, because she was not used to the exoskeleton''s force, she strained her own muscles too hard."


    "I see. I''ll pay attention." The little nurse listened to Chen Xin''s reminder, and when she bent over to hold the oxygen bottle, she also deliberately restrained her strength.


    However, a person''s habit is difficult to change in a short time. When she lifted up the oxygen bottle, she still exerted a little force. She pulled up the oxygen bottle like a radish and lost her balance. She could not help but take two steps backward and almost fell down holding the oxygen bottle.


    Chen Xin quickly held her shoulder from behind to help her stand firm again.


    The little nurse was also frightened by this. She recovered and put down the oxygen bottle again. Then she patted her chest and said, "I''m sorry, I''m too hard! It''s a little scary! "


    "Fortunately, if you don''t adjust it for the first time, you don''t need to care too much, just get used to it." Chen Xin comforted her, but didn''t find it strange.


    The little nurse also quickly adjusted herself. After converging her emotions, she tried again under the guidance of Chen Xin.


    This time, she didn''t have any more problems, but just as Chen Xin demonstrated before, she easily lifted the oxygen bottle.


    "Well done. It looks like you''ve got the knack." Chen Xin watched the little nurse successfully lift up the oxygen bottle and gave her a look of approval.


    "Mr. Chen, you taught me well. Thank you very much." The little nurse put down the oxygen bottle and sincerely said thank you to Chen Xin.


    "It''s just a little thing. Don''t be so polite." Chen Xinqian said modestly, but he didn''t forget to tell the little nurse: "it''s not difficult to use the exoskeleton. It''s easy to master the secret, but I suggest you practice more. It doesn''t matter to carry such heavy things as oxygen bottles, but if it''s carrying patients or something, if you don''t master the strength well, you may hurt people. You''d better pay more attention to practice. "


    "Well, I''ll practice more. Thank you, Mr. Chen." The little nurse sincerely expressed her thanks again, and boldly hugged Chen Xin.Confused by the little nurse''s sudden embrace, Chen Xin stepped back and wanted to pull her away. However, the little nurse''s exoskeleton provided her with assistance at this time, which made Chen Xin not push her away.


    Just then, a cry came from behind Chen Xin: "what are you doing?"


    Chen Xin quickly turns around and sees Qin LAN and Mo Qingyan who happen to come back together.


    Startled by the cry, the little nurse also responded and quickly let Chen Xin go. Quite embarrassed, she said to Chen Xin, "Mr. Chen, I won''t disturb you. I''ll leave first."


    With that, the little nurse ran away.


    Seeing the little nurse running away, Qin LAN and Mo Qingyan just came over. They looked at Chen Xin up and down together. Qin Lan said in a bad tone: "what were you doing just now? Why are they all together? Who is that woman? "


    "Ah LAN, long Niang, are you back?" Seeing that the expressions on Qin Lan''s and Mo Qingyan''s faces were not good, Chen Xin quickly explained to them: "it''s a nurse from the rescue team. She asked me to teach her how to use the exoskeleton. Just now, she fell down and I went to help her, so she hugged me."


    "Really?" Qin LAN looks at Chen Xin suspiciously. Her eyes are full of disbelief.

 Chapter 346

    By the time Chen Xin woke up the next day, Han Ping had already come back with urban support overnight.


    Although it''s really dangerous to drive late at night, considering that there is no sunlight at all and the visibility is the same, it can be completely ignored.


    But Han Ping didn''t have a rest at night when he drove back. It was really very hard. When Chen Xin saw him, his sleepiness could not be covered up.


    "Hard work, Han Ping. Go wash your face and have a sleep." Chen Xingang just woke up and saw Han Ping''s appearance. He advised him to have a rest.


    Han Ping really can''t support it. Although he didn''t have 100 kilometers to go back and forth, it took him a whole night to go back and forth on the road. He just went back to the city and had a rest while waiting for the city government to mobilize materials. At the moment, he heard that Chen Xin asked him to have a rest, but he didn''t say much. He nodded and got on the bus to have a rest.


    Chen Xinjian Han Ping went to have a rest. Then he came to the team leader who was receiving and counting materials and asked him, "what materials are supported by the municipal government? It looks like a lot of things! "


    When the rescue team came, they brought two material transport vehicles. Before they went back for help yesterday, all the materials on the vehicles had been unloaded. Now the vehicles back are not only filled with the materials urgently needed by the rescue team, but also two ordinary trucks, which are also full of materials and parked here.


    At this time, the four cars were unloading, so that Chen Xin was full of supplies.


    The team leader was also very pleased with this and said excitedly to Chen Xin: "the municipal government has allocated two sets of medical tents, and the supporting medical equipment has also been transported together, and there is also a set of spare tents. Although there is no supporting medical equipment, there are enough folding beds and heaters. With these, we can build two more severe wards and one less severe ward, so as to save people''s lives The station will be able to accommodate more people! "


    "That''s great! It''s just Chen Xin naturally felt very happy about this. He just thought of the busy work of the nurses when he helped in the ward yesterday. He hesitated for a moment and then asked the team leader, "if there are more patients, can the rescue team be busy? The number of medical staff we brought here is not large. Can we not take care of them? "


    The team leader nodded, affirming Chen Xin''s worry, but explained without worry: "you can rest assured that the municipal government has helped to call up volunteers. Today, a group of volunteers will come to help. They can share a lot of work of medical staff, and there will be no problem."


    Hearing what the team leader said, although Chen Xin is at ease with the increase of staff, he is still hesitant. After all, not everyone can replace the work of medical staff. What volunteers can do is only some physical work and some simple medical work, which may not be able to share too much.


    However, it''s better to have someone to help than no one. Chen Xin naturally doesn''t say much about it. He just remembers that the little nurse learned how to use the exoskeleton from herself yesterday. He told the team leader about it That''s what happened. I think we should take time to train all the people in the rescue team on the use of exoskeletons. At least when we need to use it, someone can use it. It can''t happen that there is a need but no one can use it. "


    "It''s really my negligence. I''ll arrange it today. Chen Xin, do you think you should teach it or let others teach it?" The team leader also reflected that he had neglected this matter and figured out who to teach it.


    Chen Xin is a suitable person for the team leader. Although he is also a member of the rescue team, he is not a medical worker. Relatively speaking, there are few things. It is not a troublesome thing for the team leader to let him be responsible for teaching the medical workers of the rescue team how to use the exoskeleton.


    However, Chen Xin refused the job.


    "I''m afraid I don''t have the time. Yesterday, I took a look at the medical tent. It''s still a little crude. The temperature inside the tent is very low with heating equipment, which is not conducive to the recovery of patients. So I plan to transform the tent." Chen Xin said his idea to the team leader, and hoped that he could find the staff in Lincheng to coordinate and get the materials needed for the transformation.


    As for Chen Xin''s ability to transform things, the team leader knew that before he came here. After all, Chen Xin is also an important talent in the country. His safety and trends can be said to be involved in a wide range. As the team leader of the rescue team, it is impossible not to know about him.


    At this time, Chen Xin said that he wanted to transform the medical tent and improve the thermal insulation effect of the tent. Naturally, the team leader was happy to see this.


    However, he was not without worry, so he asked Chen Xin, "Mr. Chen, where do you need to move to rebuild the tent? Will it affect the patients inside? In addition, what materials are needed for the transformation? On the side of the city, I had a talk with their staff yesterday. They are very short of supplies now, and they may not be able to draw anything out. "


    At this time, strictly speaking, the goods and materials in Linshi are in a state of polarization. When the goods and materials such as food and daily necessities are transported, they are calculated according to the population before Linshi, but now because of the blizzard, the population in Linshi has been reduced a lot. In fact, they are in an objective surplus state.


    But in addition to these, there is enough coal for heating. After all, although there is no shelter, there are still so many people for heating, and other shelters have to turn on the power of the boiler.For example, medicine and other materials are obviously a little nervous. After all, railways used to transport coal and other important materials before, and there was no surplus transport capacity for other materials.


    After listening to the captain''s explanation, Chen Xin also understood this point. He nodded and thought about it. Although the system is powerful and people who see it will understand what happened, Chen Xin didn''t want to be too shocking, so he said to the captain: "if so, give me the spare medical tent. I''ll use the spare one After the tent is finished, you can transfer the patients to this tent, and I''ll transform other tents. "


    "That''s all right, that''s it! When the volunteers come, I''ll send some people to help you. As for the materials I need, I''ll ask the staff in the city if they have them. If not, I''ll have to trouble Mr. Chen to find another way. " After listening to Chen Xin''s request, the team leader made a little consideration and agreed.


    Chen Xinjian agreed, but he didn''t think it was a big deal that Linshi couldn''t find the materials. He just said with a smile, "don''t worry, they can''t get the materials together. I have a way, just a little trouble."

 Chapter 347

    The number of volunteers assigned to the rescue team by the city is not large. After Chen Xin had breakfast, a team of about 50 volunteers led by the city''s staff came to the rescue station to help.


    After these volunteers arrived, they were immediately assigned to work in the reception area to help maintain order, help patients see a doctor, and go to the ward to help take care of the critically ill patients It has to be said that with these volunteers, the work of the rescue team has really become a lot easier, and the medical staff can better focus on how to treat patients.


    As he promised, the team leader sent five volunteers to Chen Xin to help him transform the spare tent.


    "Hello, we are volunteers here to help. What do we need to do?" Five volunteers came to Chen Xin and looked at Chen Xin, who was wearing his power armor today, with envy and fear in his eyes.


    Power armor, which was only seen in science fiction works before, is naturally enviable. In addition, the five volunteers are all young people, so they are even more greedy for power armor. It''s a good thing that they can''t see at ordinary times.


    However, the mechanical arm on Chen Xin''s back is quite ferocious, and it''s not surprising that he is afraid of the unknown power armor.


    Looking at their appearance, Chen Xin just laughed and said to them, "help to set up this set of tents first. I need to do some cold proof renovation for these tents."


    "OK, how can I do this?" Several volunteers did not refuse, came to Chen Xin and asked what they should do.


    "These white bags are tents. I''ll choose the right place. You just need to spread out the tents and inflate them with the air pump over there. Then you can put up the tents." Chen Xin pointed to the white bags under his feet and explained to them, "this kind of tent is easy to set up, but after that, you need to install lighting and put hospital beds. It''s hard for you."


    "This is what we should do. You help to save people. We just do some physical work. It''s nothing." Several volunteers were very modest and polite.


    Chen Xin didn''t say much. He directed five people to spread out the tent. After the tent had been laid in the selected place, he inflated it with the air pump prepared in advance.


    This kind of tent relies on the air column support inside. It only needs to be filled with air, and the whole tent can be supported. It is a kind of convenient temporary equipment. With the help of five volunteers, the first tent only took more than ten minutes to be set up.


    However, this can not be regarded as a good tent. In addition to continuing to inflate air to maintain the strength of the air column and the support of the tent, it also needs to use ground nails to fix the tent, such as lighting tubes, heating furnaces and matching hospital beds.


    Chen Xin asked two volunteers to fix the ground nails. He and another volunteer installed the light tubes to be fixed on the top of the tent. The remaining two volunteers were sent by Chen Xin to carry the beds and heaters.


    The space inside the tent is not low. If ordinary people install lights, they may have to set up a stool, but Chen Xin only needs the help of a mechanical arm.


    Looking at Chen Xin installing the light tube to the reserved position on the top of the tent with a mechanical arm, the volunteer on one side suddenly asked curiously, "brother, is your power armor made by the state? Is there such a good thing in our country? How can I get this set? Are you from the special forces? "


    "You say this? I don''t know. If you want to know, you should ask the relevant departments. " Chen Xin made a vague remark, did not elaborate on anything, and did not mention that this set of power armor was made by himself.


    Although he could understand the curiosity and admiration of the volunteer for power armor, there was no need to tell people about some things.


    When the volunteer heard Chen Xin''s words, he thought it was Chen Xin who needed to keep secret, so he didn''t ask any more questions. He just looked at the power armor with more envy.


    They were busy for more than half an hour. With the help of five volunteers, all the spare medical tents were set up.


    This set of spare tent is the same specification as the one that is now used as the ambulance station, except that the supporting medical equipment and medical staff are missing. The other parts are all the same. As long as the medical staff and medical equipment are provided, this is the second ambulance station.


    But at present, the medical staff of the rescue team is limited. Even if the volunteers are included, they are only enough to use the second set of medical tents as a new ward, and there are not enough doctors to open up a second ambulance station.


    In fact, the cold proof effect of the medical tent itself is not bad. According to the technical parameters in the manual found by Chen Xin, the tent can adapt to the temperature of - 40 ¡æ ~ 65 ¡æ, even in the severe cold weather conditions.


    It''s just that it can adapt to the ambient temperature of - 40 ¡æ, which is not enough for now, so it must be upgraded in terms of cold protection.


    The cold proof of the tent mainly depends on the space between the inner and outer layers of the tent, which is used as the heat insulation layer to achieve the effect of heat preservation.It''s just like that double-layer glass is more cold proof than single-layer glass. The efficiency of heat conduction between different media is different. Leaving space between two layers of cold proof materials to avoid heat transfer directly to the outer layer can play a better insulation effect.


    But the effect is limited, so now the medical tents are equipped with heaters for heating, which can maintain the temperature in the medical tents at a relatively low temperature.


    In addition, there is also a very important thing for the tent, which is the mat. Without a good insulation mat to insulate the heat from losing downward, the temperature in the tent is still very difficult to maintain.


    Similarly, if Chen Xin wants to upgrade the thermal insulation effect of the tent, it is mainly aimed at these two aspects.


    Chen Xin has checked before that the material of the spare medical tent and the erected medical tent is PVC airtight cloth, which is mainly used for heat preservation through a layer of cold proof cotton and the interlayer space between the inner cloth and the outer cloth.


    If you want to improve the thermal insulation effect, the first choice is of course to improve the materials. Replacing the tarpaulin and mat materials with materials with better thermal insulation performance can naturally improve the thermal insulation effect of the tent.


    Another option is to improve the structure of the tent, block the way of heat conduction, reduce the heat emission, which can also play a thermal insulation effect.

 Chapter 348

    In fact, there is not much room for structural improvement. First of all, the tent itself needs to be in contact with the air. In addition, it is a tent made of soft materials. It is impossible to create a vacuum sandwich between the outer cloth and the inner cloth of the tent, or fill some hard high-performance insulation materials to make an insulation layer.


    The traditional double-layer design is already a very reasonable structure, even in the Everest and North and south polar scientific research, this double-layer structure tent is enough.


    What Chen Xin can do is to add an inflatable heat insulation layer at the bottom of the tent to prevent heat from losing to the ground. At the same time, he can add a small porch with two layers of curtains at the door, so that when someone opens the curtain, it will not let the cold air from the outside directly enter the tent and block the heat loss inside.


    For a large tent such as a medical tent, the tent door and floor are the two main channels of heat loss. As long as the heat loss in these two places is blocked, the tent can get better insulation effect.


    In addition, it is the improvement of materials.


    Because of the cost problem, the material used for this large tent is PVC air tight cloth. As we have said before, the temperature resistance of PVC material is - 40 ¡æ ~ 65 ¡æ. Beyond this range, the properties of the material will be changed and the original performance will be lost.


    In small tents, manufacturers can use better performance materials such as PU and PE as the coating of tarpaulin, so that the tents have better protection performance.


    However, PU material, that is polyurethane, is the best insulation material in the world at present. The insulation material used by Chen Xin and his friends when they built the refuge was polyurethane coating.


    According to different material formulations, this kind of material can withstand - 50 ¡æ ~ 150 ¡æ. Among them, TPEE thermoplastic polyester elastomer, also known as polyester rubber, has excellent performance and can withstand the temperature difference between - 70 ¡æ and 200 ¡æ. It can be said that it is an excellent thermal insulation material now.


    If you can, Chen Xin certainly wants to use this kind of material to upgrade the current medical tent. Unfortunately, this kind of high-performance thermal insulation material is also in urgent need for the country. Although there is a lot of production, there is not much stock in the market.


    In the face of this situation, Chen Xin can only consider making do with some existing materials.


    For the tent reconstruction, the team leader did his best to help Chen Xin find the staff in Linshi to coordinate the materials he needed.


    Pu material, a high-performance thermal insulation material, is naturally a good steel for Linshi. It is not likely to be evenly distributed to Chen Xin to improve the tent.


    However, the staff can still provide some cold proof felt for Chen Xin.


    "Cold proof felt? How much can I get? " Chen Xin heard from the staff that there was only cold proof felt. Although he felt that the material he wanted was far from what he wanted, since there was a shortage of materials, he could only use what he wanted.


    Seeing that Chen Xin didn''t dislike the cold proof felt, the staff quickly said, "it was used for building greenhouses before the disaster in the city. However, after the meteorite impact, the greenhouses were not built, and a lot of cold proof felt ordered at that time was overstocked. I can have someone get you a batch if you need it. "


    "Well, let''s make some rolls first, and cover them on the tent for more or less insulation." Chen Xin can only say so at this time.


    When the staff went to arrange for the cold proof felt to be delivered, Chen Xin was not idle. He went back to the tent, ready to see what could be improved.


    In the tent, five volunteers assigned to him are burning in front of a heater.


    They don''t have protective clothing like Chen Xin and the members of the rescue team. They only have ordinary cold proof clothes on them. At this time, they are sitting in front of the heater, baking their shoes wet with snow, which makes the tent smell a little bad.


    Although Chen Xin was wearing power armor and had an air filtration system, he could not smell it, but he could still imagine what it was like.


    This obviously reminds him that in addition to improving the thermal insulation performance, the tent can also improve the heater, so that the heater can provide more heat.


    This is obviously Chen Xin''s old line of work, and he still has such a useful tool as a universal manipulator, and he can''t even upgrade the heating furnace system.


    Next to an unused heater to himself, Chen Xin control the power armor, some clumsily sat on the ground.


    Although this set of power armor is not as exaggerated as one or two tons in sci-fi works, it still weighs a few hundred jin. Therefore, Chen Xin is not easy to sit in the temporary hospital bed beside him. He is afraid that it will collapse directly and can only sit on the ground.


    Fortunately, flexibility was taken into consideration when designing joints at the beginning, so sitting on the ground is not a problem.


    The heater was disassembled by the mechanical arm, and the scanning equipment on the mechanical arm was used to scan the heater as a whole. While dismantling the heater, Chen Xin looked at the scanning results projected on the helmet screen and considered how to carry out the transformation.There are four heaters in the tent. Considering the safety, they are all electric heaters, powered by external power supply. As for the power supply, it is the isotope thermoelectric battery on Chen''s new car yesterday.


    The output power of an isotope thermoelectric battery is more than enough to power several tents.


    Therefore, on the premise of not worrying about the power consumption, the simplest and crude way to transform the heater is to directly increase the power. Although it is a very wasteful practice, it has to be said that many times things can be solved in this way.


    Considering that the isotope thermoelectric battery can output stable power for ten years, the power amplification of Lida flying brick is actually the simplest choice at present.


    Chen Xin chose this way just for a little consideration.


    But in this case, we need to optimize the circuit of the heater itself, at least not because the power is too large and burn or short circuit.


    Controlling the mechanical arm to continue to dismantle the heater, Chen Xin decided to try this time to complete the transformation of the heater without upgrading the system. Anyway, with such a top-level tool as the universal mechanical arm, Chen Xin doesn''t think he can''t even handle a heater.


    However, after he disassembled the heater into parts, Chen Xin discovered a fact that made him a little embarrassed.


    That is, without raw materials, even if he has a universal manipulator that can 3D print parts and do all kinds of machining, Chen Xin still can''t complete the transformation of the heater out of thin air.

 Chapter 349

    The embarrassment of not having any raw materials really put Chen Xin in a dilemma for a while. However, he soon extricated himself from this dilemma and put the parts of the heater that had been disassembled in front of him aside. Chen Xin said to the volunteers who were baking that he wanted to go out for a while, and then walked out of the tent.


    The shortage of raw materials is one of the difficulties facing Chen Xin, and also one of the problems facing the city at this time.


    Therefore, Chen Xin did not plan to find the staff of Linshi to get some raw materials to complete the transformation, but planned to find and collect some useful things in the city.


    Although Chen Xin believed that there was no problem in getting enough materials to transform the heater when he went to find the staff, considering that the staff had told him that there was a shortage of materials at this time, Chen Xin didn''t think it was necessary to do so.


    After all, with power armor and mechanical arm, it''s easy for him to find some materials.


    The ambulance station is located next to a refuge in Linshi. It was originally a prosperous commercial area in Linshi. Although most of the buildings around are buried by snow, many things can be found in the buildings.


    Chen Xin found a building that had not been completely buried by snow, and climbed in through the window that exposed the ground.


    There was also a lot of snow in the building. Although Chen Xin was able to climb in, he could not stand up straight and could only lie on the ground.


    After clearing the snow with a mechanical arm, Chen Xin reluctantly raised his head and made room for himself.


    "What a pain But fortunately, as I expected, there are still some things. " Complaining, Chen Xin raised his hand to catch the metal material cut from the ceiling with a mechanical arm, and was very satisfied with his harvest.


    In fact, as Chen Xin thought, although people have three months to prepare and collect materials before the disaster, most of the things that can be found in the buildings have been taken away, but the materials contained in the buildings themselves are not.


    The simplest example is the ceiling that Chen Xin is cutting.


    It should have been a shopping mall. The ceiling on the top floor has a gusset ceiling, which is used to hide the ventilation pipes and ugly circuit wires on the ceiling.


    This layer of gusset ceiling is made of aluminum alloy. It seems that it has been for some years. Not only is there a thick layer of dust inside, but also the metal parts between the layers are full of rust. Some of them are deformed due to disrepair.


    However, this does not prevent Chen Xin from recycling them, dismantling them one by one with a mechanical arm, and simply cutting them into the right length, and then twisting them together for easy carrying.


    In the past, these aluminum alloy parts disassembled by Chen Xin can only be sold by scrap collectors, and they are of little use.


    But for Chen Xin now, he can completely recycle these wastes.


    As long as we recycle these materials, extract the useful parts, and then use the 3D printing function of the mechanical arm to transform several heaters, it''s really not a troublesome thing.


    Of course, these materials can only be regarded as additions, not what Chen Xin came here to look for.


    Cut the ceiling gusset boards one by one, and cut the ventilation pipes behind the gusset boards. Chen Xin finally found what he wanted after removing most of the ceiling that he could see.


    Fan coil unit of central air conditioning.


    This is the terminal equipment of the central air conditioner, which includes small fans, motors and air heat exchangers. This is what Chen Xin is looking for this time.


    This kind of thing usually chooses to be installed in the ceiling or other places, so even if most of the materials in the building are recycled and disassembled, few people think of demolishing this kind of thing.


    Chen Xin will be twisted into a bunch of metal strips and cut down the ventilation pipe together into a roll, this is waving the mechanical arm to remove the fan coil.


    According to Chen Xin''s estimation, if he dismantled one, it would be enough to transform the four heaters.


    Chen Xin can''t help laughing at the fact that he is dismantling the fan coil. He seems to have a special preference for dismantling the air conditioner. In the past, he used to dismantle the external unit of the air conditioner to make the ground source heat pump, but now he is dismantling the fan coil of the central air conditioner to refit the heater. It seems that he always has a problem with the air conditioner.


    However, it''s also easy to understand that the air conditioner itself is made of a lot of metal materials, and because of its working principle, many of the above parts are not low in science and technology.


    In addition, in this end of life, no one would want to dismantle two air conditioners for recycling when collecting materials. Naturally, this kind of thing, which contains a lot of metal materials and can be disassembled into various parts, becomes the most suitable source of recycling materials.


    Chen Xin didn''t think much about this either. After removing the fan coil unit, he held it in his arms and dragged out the abandoned building together with the metal materials that had just been rolled into a bunch.


    Using a mechanical arm to lift the metal material, Chen Xin turned and returned to the ambulance station.


    When Chen Xin returns to the ambulance station, Qin LAN and Mo Qingyan just come together to find him. Seeing Chen Xin carrying a lot of scrap metal, they are both very curious."Ah Xin, you are Have you just come back from collecting junk? " Qin LAN looked up and down at Chen Xin and could only think of this description.


    However, Chen Xin nodded his head and answered positively, "I''m going to reform the heater. I found that I didn''t have the right materials on hand, so I went to collect some."


    Hearing this, Qin LAN and Mo Qingyan feel a little speechless, but they don''t say much. They just ask him, "is there anything we can help?"


    "No..." Chen Xingang wanted to say that he didn''t need help, but after thinking about it, he swallowed what he almost said and said, "yes, I just need your help. Come with me."


    With that, Chen Xin took the materials he had brought back and walked towards his car.


    Seeing this, Qin LAN and Mo Qingyan also follow Chen Xin.


    When Chen Xin comes to the car, he throws the materials he has brought back to the ground. Then he asks Qin LAN and Mo Qingyan, "a LAN, long Niang, have you heard the word electromagnetic metallurgy?"


    "Electromagnetic metallurgy? What''s that? " Qin LAN and Mo Qingyan look at each other, and they are all at a loss from each other''s eyes.


    Seeing that they didn''t understand, Chen Xin explained to them, "the so-called electromagnetic metallurgy is simply a technology that controls and influences the metal smelting process with the help of the electromagnetic force formed by current and magnetic field."


    "Why do you say that? We don''t understand! Just say what you want and how you want us to help you! " Mo Qingyan doesn''t like Chen Xin''s flashy appearance and asks him directly about his purpose.


    Chen Xin picked his eyebrows and said, "I''m going to build an electromagnetic metallurgy furnace to recycle these recycled scrap metals into usable metals. I need you to help me build this furnace."

 Chapter 350

    Qin LAN and Mo Qingyan don''t know exactly what Chen Xin said about electromagnetic metallurgy, but since Chen Xin asked them to help, they naturally wouldn''t refuse. They are doing what Chen Xin said he asked them to do.


    "Qing Yan, these metal rods have been wrapped with copper wire. Take them to a Xin." Qin LAN gives Mo Qingyan some metal rods wrapped with copper wire and asks her to take them to Chen Xin.


    Mo Qingyan takes Qin Lan''s iron bar and nods to Chen Xin.


    Chen Xin is making a strange looking machine at this time. Several metal rods also wrapped with copper wires are connected to a round turntable by him, which looks like a three legged stool that can rotate upside down.


    Mo Qingyan gives Chen Xin the metal rods she has brought. She takes a look at what Chen Xin is making and asks him, "ah Xin, what else can I do for you? Is it enough just to make a few iron bars and wrap copper wires? "


    "That''s enough. I can do everything else myself. The machine itself is not complicated." Chen Xinchong and Mo Qingyan smile, saying that it is enough.


    Several metal rods Mo Qingyan took over were welded on another disk with a mechanical arm. Chen Xin then assembled the two disks and the other mechanical arm together.


    Mo Qingyan looks at Chen Xin putting this thing in place and thinks it looks like an egg beater. She can''t help but wonder how it works.


    Asked Chen Xin about her doubts, Mo Qingyan did not expect an answer, because she felt that even if Chen Xin explained, she might not be able to understand.


    "This thing uses these metal rods as electrodes, and then discharges the metal materials placed in the middle. By using the arc generated by the discharge, these metal materials can be melted." Chen Xin assembled the machine, turned several metal rods on the disc like chicken feet, and introduced to Mo Qingyan, "as long as the current is strong enough and the arc temperature is high enough, nothing can''t melt."


    ¡°(¡Ño¡Ñ)¡­¡± Mo Qingyan said she didn''t understand what Chen Xin was saying.


    Chen Xin was not upset about this, but just said with a smile: "it doesn''t matter if you don''t understand. You just need to know that I can use this machine to melt the recycled metals and turn them into new materials."


    "Oh, so it is!" Mo Qingyan has a "I fully understand" expression.


    Chen Xin can see that Mo Qingyan doesn''t understand at all.


    However, he didn''t care. After the machine was installed, he connected it to another isotope thermoelectric battery which was removed from his car and planned to use this battery for power supply.


    Now one of the three batteries on the car is removed to supply power to the ambulance station, and the other is used here by him. Now there is only one battery on the car to supply power. On the premise that Chen Xin does not install the battery back, the car can not be driven for the time being.


    This has little effect on Chen Xin. Now he only needs to live in his car, but he doesn''t need to use it. He doesn''t need to drive for the time being. Even if he needs to, it won''t take much effort to build a battery temporarily or install it back.


    Of course, the device in front of him is just a very simple one. To be able to use it, Chen Xin still needs to invest some survival in it.


    The investment of survival makes the machine look brand new, and at the same time, it becomes more science fiction and something like that. A simple description is that it has changed from green skin painting style to NEC painting style.


    The overall shape of the machine has not changed much. It is still a pillar connecting the upper and lower discs with several metal rods.


    The bottom disc is like a large tray, surrounded by three metal rods, which still looks like a chicken claw, while the top is slightly different. Several metal rods turn black, which looks like a plug.


    After the upgrade, Chen Xin was very satisfied with the machine and decided to try the effect of the machine.


    After putting some scrap metal on the bottom disc and motioning Mo Qingyan to step back, Chen Xin pressed the start switch of the machine.


    With the power on, the three metal rods at the bottom of the machine rotate. With the acceleration of speed and the increase of current, the waste metal on the tray surrounded by the three metal rods gradually shake up and then suspend.


    "The three metal rods are actually electromagnets. They rotate at high speed to form an electromagnetic field, so they can absorb the waste metal." Chen Xin explained to Mo Qingyan and Qin LAN who didn''t know when to come. At the same time, he saw that the rotation speed of the metal rod had been able to hold the suspended waste metal steadily, so he pressed the second switch.


    Several metal rods on the plug at the top of the machine are lowered slowly until they touch the waste metal suspended in the middle of the machine, and then the discharge begins.


    The bright electric arc is released from the electrode on the top of the metal rod, hitting the suspended waste metal. While crackling, there are also violent electric sparks. Qin LAN and Mo Qingyan can''t help but raise their hands to cover their eyes, while Chen Xin has already pulled down the light shield on the mask.


    With the sound of the arc, the waste metal constrained by the magnetic field began to melt gradually, and the electric spark released from the electrode became more and more bright, which looked like welding.Qin Lan''s power armor also has a light shield. She pulled down the light shield to see that the waste metal in the machine had melted into a mass of orange red liquid under the action of electric arc.


    The molten liquid metal releases a lot of heat, which makes the snow around the machine begin to melt, transpiration a lot of steam, but because of the high temperature, it is directly sublimated into water vapor.


    However, although it has melted into a mass of liquid, the liquid is still constrained by the magnetic field and suspended in the middle of the machine.


    "Ah LAN, what''s the situation?" Mo Qingyan''s helmet has no light shield. At this time, she can only put one hand in front of her eyes and ask Qin LAN.


    "I don''t know. It seems that after ah Xin started the machine, a lot of electric sparks came out, and then the scrap iron melted. Now it seems that there are impurities dripping down." Qin LAN adjusted the sight on her helmet and switched the visual mode. Then she saw that there were black impurities on the surface of the metal solution, and then they fell on the tray below.


    At this time, Chen Xin has no mind to answer Qin Lan''s and Mo Qingyan''s questions. With the operation of the machine, Chen Xin is also very focused on the machine, looking at the mass of orange red liquid metal, and constantly monitoring its state through the scanning equipment on the mechanical arm.


    "The machine is still a little simple, it can''t control the temperature, and it''s difficult to discharge impurities. It seems that it needs to be improved." Chen Xin was not satisfied with the gradual stratification of liquid metal in front of him.

 Chapter 351

    New metal materials are obtained from waste metal recovered by arc smelting, and then the melted metal materials are processed into required parts by mechanical arm. Chen Xin finally completes the transformation of several heaters in the tent.


    When Chen Xin was engaged in electric arc smelting, the staff of Linshi also sent the cold proof felt that he had promised before, so that Chen Xin and the material of the medical tent were upgraded.


    Although there are some twists and turns, Chen Xin is very satisfied with the renovation of the medical tent in the case of insufficient materials.


    After finishing everything, Chen Xin finds the team leader and tells him that the new medical tent can be put into use.


    "Is it ready to use? That''s great, so we can take in more patients. " The team leader was very happy about this, and quickly arranged for the doctors of the rescue team to transfer the new patients to Chen Xin''s transformed medical tent.


    The staff of the city are also very excited about this. For the present city, other aspects can still support it. The municipal government is also making efforts to improve the situation and actively carry out post disaster reconstruction.


    But in the aspect of medical treatment, the pressure brought by excessive patients has directly crushed the medical system of the city. Although the arrival of the rescue team has slightly improved the situation faced by the city, the role that the rescue team can play is still a drop in the bucket for the whole city.


    It is undoubtedly good news that more beds can be set up to receive more patients.


    Although the effect of this is still limited, and only a small number of patients with serious illness can be admitted to the ward for treatment, it is still a valuable hope for the city.


    Looking at the team leader arranging for new patients to be transferred to the ward, Chen Xin did not disturb his work. Instead, he took the staff to one side and asked each other, "what is the biggest difficulty in the post disaster reconstruction of Lincheng city?"


    Although it is very important to transform the medical tent and help the rescue team treat patients, Chen Xin is not a doctor and is not good at treating patients and saving people. Therefore, he thinks that he should play his role in a more suitable field.


    For Chen Xin, the place where he can give full play to his strength is undoubtedly to help them upgrade what they urgently need in view of the difficulties faced by Linshi.


    "The primary problem we are facing is the lack of medical resources. In addition, it is the railway station." The staff didn''t know Chen Xin''s purpose, but when asked by the other party, they said the main problems facing the city: "as you have seen, there are too many patients and a serious shortage of medical staff. As a result, a large number of patients in the city can''t get effective treatment. Although your arrival has solved some of the problems, there are still many people who don''t get effective treatment Methods to get timely and effective treatment.


    As for the railway station, the whole railway station is now covered with snow. Even if there is a train coming into the station to transport materials, it is difficult for us to load and unload them effectively, which makes it very difficult for us to obtain materials. Moreover, the station warehouse buried together with the railway station also makes us have no suitable place to store the materials even if we unload them. Now it is very troublesome ¡£¡±


    "Didn''t you try to dig out the railway station?" Chen Xin has some doubts. Since he knows what the problem is, why don''t he organize people to clean up the snow at the railway station and dig it out.


    "We want to do that, too! But the problem is that the vast majority of people are sick now. Even the people who have gathered together to load and unload materials are reluctant. How can we have hands to clean up the snow in the railway station? " The staff gave a bitter smile.


    Of course, they also want to clean up the platform so that the train can enter the station to unload, but the problem is that they really don''t have hands to clean up the station.


    Before the blizzard brought heavy damage to the whole city, a large number of survivors fell ill because of the low temperature, but the rest of the healthy people were transferred out because the city government had to maintain supplies, and braved the Blizzard to load and unload supplies for the railway.


    This kind of struggle lasted for a whole month, which consumed a lot of living force in Linshi. After all, there is a high probability of frostbite, cold, and even death in the environment of minus 70 degrees.


    Now, although the Blizzard is over, there are few healthy survivors who are not ill in the city.


    This is something like the blizzard in the ice age. If the technology of cold prevention and heating is not fully used, the patients who blow up the watch will surely get sick when a blizzard comes down. Even the doctors themselves will get sick, and most of them will die soon.


    At this time, the limited number of workers who can work will naturally be sent to maintain the access to urban resources, and then the medical system will operate as much as possible, so that the sick can recover.


    At this time, it is meaningless to waste resources to upgrade the house, because the Blizzard has passed, and the heat preservation of the house can be maintained at an acceptable level.


    It''s just that reality is not a game. In the game, engineers can do research or become doctors. If they have the resources, they can build a hospital right away. But in reality, these are impossible.


    A professional medical staff needs five years of medical education in the university to be trained. A little more skilled also needs a lot of time to accumulate clinical experience. It can be said that every medical staff is very valuable.That''s why before the disaster, when the epidemic happened, Yanguo needed to send medical staff from all over the country to support the epidemic areas, because the medical system would really collapse in the face of a sudden increase in the number of patients.


    As a result of the collapse of the medical system, it will be a complete tragedy and disaster.


    In fact, the medical system at this time has collapsed, and the arrival of the rescue team just pulled it back from the collapse, but it did not achieve the real sense of turning the situation around.


    However, this is the limit that the rescue team can achieve. Unless Chen Xin can upgrade the medical equipment of the rescue station to the medical cabin in the science fiction works, the situation will not be greatly improved.


    After all, even if they are treated, it will take time for the patients to recover. Unless it''s the kind of medical cabin in science fiction where people lie down to sleep and get better after they get sick, it''s hard to make a big difference in the current situation of the city.


    However, even if Chen Xin is willing to survive to transform the medical cabin, he can''t get anything under the current situation of lack of materials. It''s impossible for him to save resources by recycling scrap iron from the semi-finished electromagnetic furnace he made himself?


    Therefore, to improve the situation of the city, Chen Xin thinks that digging the railway station out of the snow so that materials and external support can smoothly enter the city is the first thing to bear the brunt of the moment.

 Chapter 352

    When Chen Xin, Qin LAN and Mo Qingyan came to the original railway station near the city, what they saw was a ravine like a canyon and a snow plain completely buried by snow, with almost no traces of architecture.


    Gully is the original railway, although there is a certain amount of snow on it, but there are often trains passing by, so that there is not much snow on the railway, so that a gully like trace is left in the snow.


    The railway station in Linshi was the fourth-class station in the station classification before the Yanguo disaster, which was only one level higher than the lowest level used for train passing and overtaking.


    The station itself is a small flat building, even lower than the surrounding houses. After the blizzard, it will be completely covered with snow without any trace.


    After all, it was a small station with only five trains a day before the disaster, and it was unnecessary when the place was big.


    Before the disaster, Linshi was also trying to expand the railway station and build a loading and unloading station, but obviously this work has not been completed.


    From the side of the gully formed by the train passing through, we can still see some traces of the loading and unloading stations built before. After all, Linshi still has to load and unload the trains transporting materials to them.


    It''s just that the snow around is more than ten meters deep. When you look down from the gully, it''s like looking down from the top of a four story building. You can''t help feeling that everything created by human civilization is not worth mentioning in front of the great power of nature.


    However, although the snow here is deep, a large part has been dug up to form a relatively gentle slope.


    This is obviously a place for loading and unloading goods and materials in the city. Otherwise, it is not an easy job to jump from the snow top of four stories to the track below.


    Even if you can''t fall to death in the snow, it''s impossible to transport the materials under you without digging out a slope.


    "Ah Xin, how do you dig out the railway station? This railway station is not big, but there is so much snow. Even if you have enough hands, you have to dig for several days, right Qin LAN stands beside Chen Xin and takes a careful look at the railway below and asks Chen Xin.


    Chen Xin shook his head, for Qin Lan''s question, he was very helpless and said: "several days? Ah LAN, you underestimate the workload. Even if you give 200 people, it will take at least 10 days and a half months to dig out the railway station. Only after they are equipped with exoskeleton protective clothing can they make this progress. Otherwise, you may be able to dig out the original roof of the railway station in a month or two. "


    "Ah? In that case, how do you dig out the railway station? " Qin LAN can''t understand what Chen Xin is thinking.


    It is clearly said that they want to come to the field to investigate how to dig out the railway station so as to make the train loading and unloading more efficient. But now they say that even if there are enough people, they can''t clean up the railway station in a short time. Isn''t that self contradictory?


    "Of course, it''s not hand dug. It''s too inefficient and there are not enough people." Chen Xin walked towards the slope in front of him. As he slid down the slope, he continued to say to Qin LAN: "I''ve come to see if there is any way to remove the snow more effectively. It doesn''t need a lot of manpower. It''s easy to say even if the time is slower."


    "Do you have any idea?" Qin Lan also followed Chen Xin to slide down. Both of them were wearing power armor, so it was more convenient to slide down than to walk down.


    Standing at the bottom of the gully and looking up, Chen Xin has a more intuitive feeling about the thickness of snow. He turns on the measuring function of the mechanical arm and measures it. He finds that the thickness of snow is 10.12 meters. It''s a huge project to empty the railway station just by digging.


    Even with the help of construction machinery, it is not an easy job.


    As for clearing only one platform to facilitate unloading, it''s OK, but the problem is that there is no one available to do it.


    So now either wait for the situation in the city to improve and the patients with mild symptoms to recover and get enough labor force, or wait for the city to find a way to send new reinforcements, or Chen Xin can think of a way to directly evaporate the ten meters of snow in front of him.


    Evaporation is actually a feasible idea. As long as it can create a large enough heat source to raise the temperature of the railway station to above zero and melt the snow, it only takes a few days to melt the snow here.


    But the problem is that in the current environment, it is also a problem to create a large enough heat source, not to mention where the energy comes from. After the heat source is produced, how to ensure that the heat can spread to the whole railway station.


    Although the fourth-class railway station is only a few hundred meters long, it looks very small, but such a large area depends on a heat source to maintain heat and evaporate the snow here. All Chen Xin can think of is the heat supply field that can be created by the energy tower and heating hub in the ice age game.


    Fortunately, this is not something that Chen Xin can''t do at all. After all, he was thinking about this problem before, but now, instead of using the energy tower to build a greenhouse, he uses it to dig a railway station first.


    Just want to build an energy tower, in addition to the need for a lot of materials, but also need to drill a geothermal well deep enough.The problem of materials is easy to solve. Chen Xin now has an electromagnetic metallurgical furnace. With this furnace, he can obtain materials for building energy towers by recycling the waste metal in Linshi.


    But drilling a geothermal well deep enough requires not only professional equipment, but also professional drilling personnel.


    Thinking of this, Chen Xin responds that there is a drilling expert in Lincheng?


    So Chen Xin quickly asked Qin LAN, "a LAN, you went to" Da Ren "yesterday. What''s his situation like?"


    "What about the" talent "? He''s in good condition. He dug a hot spring when he was digging a well for himself. He can live well by the hot spring. Ah Xin, why do you ask? What can I do for him? " Qin LAN hears that Chen Xin seems to need "drilling experts" to do something for him.


    Chen Xin nodded and said to Qin LAN, "let''s go to find the" talent ". I need him to help me drill a well."


    "Drilling? But ah Xin, didn''t you just talk about clearing away the snow at the railway station? What does drilling have to do with that? " Qin LAN is confused by Chen Xin. She doesn''t understand how drilling and clearing snow are connected.


    Chen Xin cocked up his mouth confidently and said to Qin LAN with a smile: "the answer just now, didn''t you mention it yourself? "Daren has dug a hot spring, so he can rely on the hot spring to resist the cold. So I asked him to help me dig a deep well. I want to use geothermal energy to evaporate the snow here."

 Chapter 353

    Chen Xin is not a person who will delay. He and Qin LAN come to the home of "drilling master" directly from the railway station. They plan to ask him for help to drill a deep geothermal well to build an energy tower.


    The home of "drilling master" is located at the foot of a mountain in the suburb. Because of its location, the snow here is not so deep, and it has been cleaned up, so that Chen Xin can see that it should be a courtyard similar to a small factory.


    It seems that the yard and the factory building have been abandoned, but the snow has been cleared up so that Chen Xin and Qin LAN can enter the yard from the outside and see that the yard is obviously equipped with a protective door.


    Behind the protective door should be the refuge of "drilling master". It seems that like Chen Xin, he chose to dig a living space against the mountain, effectively using the mountain as the protective layer of the refuge.


    Chen Xin and Qin LAN contact the "drilling expert" through the radio on the power armor, and soon he opens the protective door and appears in front of Chen Xin and Qin LAN.


    "I haven''t seen you for a long time," he said Chen Xin greets the "drilling expert" and looks at his friend whom he hasn''t seen for more than a year.


    "Drilling master" is a middle-aged man who is nearly 40 years old. In Chen Xin''s memory, he used to be very rich and well maintained. Although he works on the construction site all the year round, like a contractor, he is very generous and kind, and he is the big brother in the survival group.


    But now the "drilling master" looks a lot thinner, the whole person is also a lot older, and his black hair has become white. Obviously, it took him more than a year to bear a lot of pressure before he became like this.


    However, in spite of this, the forthright and cordial character of "drilling talent" has not changed. He warmly greets Chen Xin: "it''s a writer! Long time no see. Welcome! What brings you here? Come on, come in and sit down! "


    Then he called Chen Xin and Qin LAN into his refuge.


    Although it is similar to Chen Xin''s refuge, which is excavated in the mountain, the "drilling master" here is still different from Chen Xin''s home. He did not dig a tunnel like Chen Xin to dig the refuge in the mountain, but dug it directly along the mountain wall.


    Although the protection ability is slightly poor, the construction difficulty is much smaller and the cost is relatively lower, which is a more economical and applicable method.


    After Chen Xin and Qin LAN entered the shelter and sat down, Chen Xin said his intention: "Daren, is your drilling equipment still there? I need you to help me drill a deep well


    "Deep well? How deep are you going to drill? " Talking about his own professional field, "drilling master" showed his confidence as a master: "my drilling equipment is still in service, and I can start work after maintenance. It''s not my boast. My drilling rig can drill hundreds of meters deep. How deep do you want to drill? Three hundred or five hundred? "


    Hearing this, Chen Xin shook his head and said with a smile, "it''s not 300, it''s not 500, it''s 3000. I want to drill a 3000 meter deep well."


    "Three thousand meters?! Are you kidding, writer? " Hearing Chen Xin say that he wants to drill a 3000 meter deep well, even if he is called "master", he can''t help shaking his head: "if you want me to drill a well of three or five hundred meters, you want me to drill it casually, but 3000 meters I can''t do that. "


    Chen Xin was not surprised to see that the "drilling expert" said that he could not do it. Instead, he asked him seriously: "what are the reasons why you think you can''t do it? Your rig is not good, or your technology is not good? "


    "There are two reasons. I haven''t drilled that deep, and my rig can''t drill that deep." "Drilling master" is very helpless shaking his head, a deep look at Chen Xin, his request is speechless.


    However, even so, the "drilling expert" explained to Chen Xin: "although my old Cao called himself" drilling expert ", he was just a man who helped people to drill machine wells. As you know, the local writer of Hunan Province, if he could not drill down 50 meters without water, he was short of water. A few deep wells were drilled in the mountains before, because of the thick soil layer on the mountains A well hundreds of meters deep.


    But now you want me to drill a 3000 meter deep well, not to mention that the maximum depth of my drilling rig can only drill 1000 meters. I don''t have any experience in drilling such a deep well!


    Drilling is nothing else. If you go down and drill directly into the rock formation or something, it''s OK to say that if you drill into the water layer or magma or something like that, this well will be abandoned. "


    The real name of "drilling expert" is Cao Daren. That''s why he gives himself the nickname of "drilling expert". Moreover, because it sounds like a word different from the tiger of serious crime group, he prefers to be called by others.


    However, although Cao Daren gave himself the nickname of "expert", he still knew very well that drilling is not to drill anything else. Although as long as the drill bit is hard enough, the drill pipe is long enough, and how deep a well can be drilled out, there are all kinds of problems in the process of drilling. These are not to say that the drill bit is hard enough and hard drilling can solve them.


    Blowout, overflow, sticking, lost circulation, collapse Since he began to work in this field in his twenties, Cao Daren has encountered all kinds of problems for more than ten years. He deeply knows that every time the drill moves one meter underground, the possibility of all kinds of problems will increase by one point.A 3000 meter deep well can never be drilled easily.


    After hearing what Cao Daren said, Chen Xin thought about it for a while and then said to Cao Daren, "if I can help you solve the problem of drilling rig, can you try to drill a 3000 meter deep well?"


    "It''s not just about the rig. I''ve never drilled such a deep well before." Cao Daren smiles bitterly. He is not unwilling to help, but really knows the danger of drilling a 3000 meter deep well.


    However, facing Chen Xin''s eyes, he thought about it for a while and then replied, "if you can help me get a professional deep well drilling rig, I can try it, but I don''t guarantee that I can drill so deep. Besides, I can''t do it alone. At least you have to find some helpers for me."


    When Chen Xin heard Cao Daren say this, he nodded his head clearly. It seems that it is impossible to drill a deep well directly into the deep stratum to bring out the geothermal energy in the deep stratum, as he thought before.


    At present, the most appropriate way is to drill a shallow geothermal well, build the energy tower, and then upgrade the energy tower to deepen the well, so as to exploit deeper geothermal resources.

 Chapter 354

    Drilling sounds like a very technical job, but in fact it is.


    Yanguo has a tradition of drilling since ancient times, but in ancient times it was called drilling. In addition to the common wells, there are salt wells, mines, and even natural gas wells.


    It''s not easy to drill a well in ancient times. It''s totally up to people to go down to the bottom of the well and dig by hand. It takes a lot of time and effort to drill a deep well.


    Therefore, before drilling a well, we must choose a good location first, and then we can start drilling.


    Although drilling now is much easier than drilling in ancient times with mechanical assistance, the technical content is not reduced at all.


    It''s OK for an ordinary well with a depth of tens of meters. For modern drilling machines with a depth of tens of meters or hundreds of meters, drilling a well with a depth of tens of meters is only a matter that can be done in a few hours, as long as the geological conditions are not particularly complicated.


    But looking for water vein, determining drilling location, analyzing geological structure and so on It doesn''t mean digging down anywhere.


    Drilling a deep well is even more troublesome. It requires not only professional engineering personnel, but also geological experts to analyze the local geological environment to determine whether drilling will cause geological damage, and then select a relatively easy place to drill and start drilling.


    In the process of drilling, we also need to deal with the three high problems from the formation itself, high temperature, high pressure and high ground stress.


    These three are also the three major problems that restrict the drilling depth, and they are the great test of drilling technology.


    "This is my drill. It''s just an ordinary drill. Although it can drill a depth of 700 meters, the drill is also an imported drill I specially bought. It can withstand high temperature and high pressure, but it''s impossible for this equipment to drill a deep well. If you want to drill a deep well of several thousand meters, you have to use a large-scale drill for drilling oil." Cao Daren took Chen Xin and Qin LAN to visit the rig he stored in the factory and introduced the rig he owned to them.


    Just now Chen Xin had learned about the situation from Cao Daren, so he didn''t have any questions about what he said. He just looked at the drill in front of him and said to him, "I can transform your drill so that it can drill to the required depth."


    "Rig modification? Writer, do you have the ability? " Cao Daren accidentally raised his eyebrows, but when he saw Chen Xin''s power armor, he nodded suspiciously, but he still didn''t guarantee: "the drilling rig is just a tool, and the main thing is to solve all kinds of problems that may occur in the drilling process. I haven''t done this kind of work. If I try to find out everything from the beginning, I''m afraid it will take less than half a year to finish it, and I can''t guarantee a long time The success rate of fixed drilling


    Cao Daren has enough say in this matter. He said that he does not guarantee the success of drilling. Although he is modest, he is not sure.


    "If there is a high-performance drilling rig, can it increase the confidence of success?" Chen Xin asked Cao Daren uncertainly that with the ability of the system, even if he wanted to drill the moon with a laser drill, it was not impossible. If experience was not enough to ensure success, he would use equipment and technology to make up for it.


    Cao Daren didn''t doubt him about this. After thinking about it for a while, he said: "if there is a good drilling rig, the success will be more certain. After all, some professional drilling rigs drilling a depth of one or two kilometers are the same as playing, but it is also related to the stratum. If it is to drill into granite, it will be a lot of trouble, just the soil layer, it will be very fast."


    "OK, let''s do it first. I''ll try to transform your rig into a large rig that can drill that deep, and then we''ll prepare for drilling." When Chen Xin heard what Cao Daren said, he was relieved.


    But Cao Daren suddenly asked: "writer, what do you want to do with such a deep well? If you drill a well for 50 meters, it will be finished. Even if you drill a deep well for three or five hundred meters, the hot spring has already come out! "


    The geothermal resources in Linshi are quite rich. Although there are no geothermal hot springs on the surface, there are geothermal hot springs underground. Cao Daren himself dug out the hot springs after more than 100 meters.


    "I want to get deep geothermal, so I have to get this deep." Chen Xin explained to Cao Daren why he had to drill a 3000 meter deep well, but he also told Cao Daren that he didn''t have to go to the right place at one time: "deep dry hot rock geothermal resources are distributed in the depth of 3000-6km. Only by drilling a well deep enough can we exploit it. However, if you think it''s difficult to drill a deep well, we can drill a well several hundred meters first Well, take advantage of the underground hot spring. "


    Hunan Province is a province rich in geothermal resources. Most areas of the province are rich in shallow geothermal energy and hydrothermal geothermal resources. Deep dry hot rock resources are also widely distributed. Linshi just belongs to the area with hydrothermal geothermal resources, that is, hot spring resources. The temperature of hot spring is not high.


    Therefore, whether Chen Xin plans to drill deep wells or shallow wells, he can exploit geothermal resources, but the geothermal resources mined by deep wells are more abundant, the temperature is higher, and they are more in line with Chen Xin''s needs.


    Hearing Chen Xin say to drill a well several hundred meters to test water, Cao Daren''s worried expression suddenly disappeared, and the whole person seemed relaxed. He said to Chen Xin with a smile: "if it is like this, it will be too simple. I can''t guarantee it in other places, but if it is within the scope of the city, I will drill a well, not say 100% hot water, but 80% hot water Chance to give you warm water! ""Yes? In that case, I need to dig a well in the location of Linshi railway station. I need to draw out underground geothermal energy to evaporate the snow in the railway station. " Chen Xin was a little surprised at Cao Daren''s self-confidence at this time, but since he was so confident, Chen Xin naturally asked him to drill a well first.


    When Cao Daren heard Chen Xin''s words, he almost dropped his eyes to the ground in surprise. He looked at Chen Xin in disbelief and asked uncertainly, "how can we use geothermal energy to evaporate the snow in the railway station? This Can this really be done? "


    "From the theory of physics, it can be done, but only if you help me dig out the well first, and you have to dig into the hot spring." Chen Xin looks at Cao Daren and asks him.


    Cao Daren was not confident again, but after hesitating for a while, he nodded and said, "if you can help me improve the drill so that the drill can reach a depth of 1000 meters, I can guarantee you a hot spring!"


    "Yes? We''ll see. " Chen Xin saw that Cao Daren agreed to come down, and then a smile appeared on his face.

 Chapter 355

    On the square in front of Linshi railway station, a drilling machine has been set up and is drilling down.


    "Pay attention to clean up the gravel and soil, don''t let them pile around the drilling hole!" Cao Daren is now standing beside the drill with great energy, wrapping himself up like a bear and directing several workers who are helping at the side of the drill.


    The feeling of returning to his old career is a very rare opportunity for Cao Daren, which makes him full of enthusiasm for this job.


    Chen Xin helped him find these workers. After the rescue team opened an ambulance station to treat the patients, some of the mild patients recovered after two days'' rest and were ready to work.


    Most of them were assigned to places in urgent need of manpower by the municipal government. Relying on the face of the rescue team and the municipal government''s own desire to clean up the railway station, Chen Xin brought in ten workers from the staff to help him and Cao Daren work together.


    Since Cao Daren agreed to help, he would not miss anything. After Chen Xin helped him find the workers, he pulled his rig to the railway station square with more than ten meters of snow. Without doing any geological survey, he directly set up the drill to start drilling.


    It''s not that Cao Daren is reckless, but that the whole city of Linshi is located in the geothermal fissure, and you can drill down to the geothermal zone.


    This geothermal fissure is the largest geothermal belt in Hunan Province. It runs through the whole province, not to mention Hubei Province. Chibi City, Hubei Province, where Chen Xin once visited, is also on this geothermal belt.


    Moreover, the geothermal resources contained in this geothermal zone are quite rich. The only two hot springs with water temperature over 100 ¡æ in Hunan Province are the embodiment of this geothermal zone.


    However, although Cao Daren is full of energy in drilling, but he is not without worry.


    "Writer, the snow is so deep underground. If we drill into the geothermal layer, the heat will rise and cause the snow to melt, which will affect the stability of the drilling rig. Moreover, your purpose is to evaporate the snow here. It is impossible to stand the wellhead more than ten meters above the ground?" Cao Daren finds Chen Xin, who has just returned from collecting materials, and tells him his worries.


    Chen Xin naturally considered this issue and comforted Cao Daren: "don''t worry about this. I will drill support columns under the rig to fix the rig. Even if the snow begins to melt, there will be no problem with the support columns supporting the rig."


    "Well, since you''re ready, I''m relieved." Cao Daren didn''t ask Chen Xin where he would stand the wellhead at that time. In his opinion, as long as the drilling rig can keep stable, the rest is not a problem.


    Chen Xin saw that Cao Daren had no other questions, so he came to the electromagnetic metallurgy furnace with the scrap metal he had just collected.


    In order to facilitate the construction, Chen Xin has moved this electromagnetic metallurgical furnace here, and has carried out the secondary upgrade, and adjusted some problems encountered in the previous use, so as to make it more efficient and convenient.


    Put the scrap metal on the tray in the middle of the machine, start the machine, and after a burst of spark charging and cloud steaming, a spherical metal ingot with fire red is melted.


    Turn off the machine, let the ingot cool down quickly, and fall back on the tray. While Chen Xin picks up the ingot with his mechanical arm, he also cleans up the residue on the tray and throws it into an iron bucket beside the machine.


    These residues are wastes, but they can''t be thrown everywhere. They will be collected and treated in a centralized way.


    Of course, the spherical ingot is not useful. Chen Xin still needs to process it again.


    With the help of the mechanical arm, the ingot, which was originally just an iron lump, was processed into various metal parts and then put aside.


    It''s just that most of these parts look like long strips of metal and various rings. Before Chen Xin completely assembled them, he couldn''t see what they were.


    However, Chen Xin doesn''t care about this. These parts are made according to the drawings stored in his micro-computer on the mechanical arm, and each part has its corresponding number. At that time, you just need to assemble them according to the drawings.


    As for what is assembled, even if someone has seen Chen Xin''s design drawings, they must have a good guess to reflect what it is.


    After all, before Chen Xin made this thing, no one in the world would build a large radiator more than ten meters high.


    This is a device designed by Chen Xin after the heating hub in the ice age. It looks like a heating hub in the game in terms of shape, but its working principle is quite different. It''s not coal-fired.


    Its bottom will be connected with the geothermal well drilled by Cao Daren, and the underground heat energy will be continuously extracted through pipeline circulation. After it is transmitted to the ground, it will be emitted through the heat sink on the heating hub, so as to improve the temperature around the heating hub.


    This is a rather rough and wasteful way of using energy, because it dissipates heat directly to the air, and there is no thermal insulation measures around. It needs a lot of heat energy to raise the temperature. If this heat energy is used for power generation or building a house for heating, it is much more efficient.But for Chen Xin, this is the most appropriate way to achieve his goal of evaporating the snow around the railway station.


    In addition, for him who has a system, he can completely improve the drawings to make the heating hub work more efficiently, and really form a stable heating field around like the heating hub in the game.


    This is not difficult for Chen Xin to achieve.


    And according to his plan, after the construction of the heating hub is completed, he will continue to upgrade the heating hub, turn it into a real energy tower, and extend the geothermal well at the bottom of the tower into the dry hot rock, so as to exploit the deep geothermal energy efficiently.


    As for the waste caused by rough use, there is no need to worry. Compared with the geothermal resources used by Chen Xin, the geothermal resources under the stratum can be regarded as endless.


    Unless the core of Bluestar goes out, the geothermal resources will be inexhaustible. As long as we pay attention to the mining methods and do not cause geological damage or over exploitation, there will be no problem.


    Relying on the electromagnetic furnace, Chen Xin continuously smelts the collected scrap metals, and has assembled most of the parts. Next, as long as Cao Daren has drilled the well, Chen Xin can start to build this heating hub.


    At that time, as long as the heating hub is put into operation, a continuous stream of heat energy will melt the surrounding snow, realizing Chen Xin''s goal of clearing the snow here.


    However, thinking that all the snow will melt at that time, Chen Xin has to consider a problem, that is, how to drain the water after the snow melts.

 Chapter 356

    Chen Xin and Cao Daren are doing hot work, but the operation of Linshi railway station has not stopped.


    Or to put it another way, it should be called that the transportation of railway materials near the city has not stopped.


    During the time when the rescue team arrived in Linshi, there were still trains that would deliver much-needed materials and coal to Linshi every week.


    The city also needs to organize a large number of people to unload materials and coal as much as possible during the period when the train stops.


    Perhaps such an operation has been organized before, or it may be that it is easier to load and unload materials without the interference of the snowstorm after the end of the snowstorm, or it may be a combination of the two. Chen Xin sees that Linshi municipal government has organized a large number of labor forces. After the train stops, it begins to move the materials on the train like ants.


    As I have said before, due to the time limit specified in the train timetable, the stop time and travel time of each train are fixed. In this case, if the materials can not be unloaded as soon as possible, the train will leave because it has reached the stop time.


    For a city which itself is short of materials, this must be unacceptable.


    Although the staff on the train are not unkind and will help them as much as possible, the help they can provide is also limited. It''s just that the original half-hour stop time is extended by three to five minutes. After all, they can still get the two to three minutes back by running faster on the road.


    Therefore, the municipal government will organize a large number of people to carry the materials transported by the train in the way of ants.


    But even if a large number of people are deployed in the city, we are also working hard to carry the materials on the train, but the time is still limited, and the loading and unloading efficiency is also limited. Although most of the materials have been unloaded within the time limit, some of the coal has not been unloaded.


    The train whistled, and the staff on board helped the people near the city to load the last bag of coal, which closed the door after the wheels rolled.


    As the train drove away, these people sorted out the materials they had just unloaded and prepared to transport them away.


    At this time, Chen Xin also withdrew his attention and prepared to go back to manufacturing the parts of the heating hub. Now he has melted enough metal ingots and manufactured almost all the parts. He will soon be able to build the heating hub.


    But just as Chen Xin turned and walked back, someone stopped him from behind: "Mr. Chen, wait a minute!"


    Chen Xin stops, turns his head and sees two people in protective clothing.


    This surprised Chen Xin a little. Although Linshi also received exoskeletons and protective clothing, the number was not large. A considerable number of people who came to load and unload materials just now only wore their own clothes and did not have protective clothing.


    When they came to Chen Xin, Chen Xin recognized that one of them was a researcher from a scientific research institution in the city. Chen Xin, who came with him, seemed to have the impression that he had seen him in Sanzhen, but he didn''t remember clearly.


    "Hello, Mr. Chen. I''m from the scientific research institution in the three towns. We met once before." The man introduced himself to Chen Xin and explained his intention: "I came to see you from three towns."


    "Come to me from three towns? What''s the matter? " Chen Xin picked an eyebrow, can''t help but wonder what it is that makes the people in front of him come to find himself from Sanzhen.


    "The thing is, because of Mr. Chen''s coming to the city, many of the projects you cooperated with us have been affected, so I came here specially to ask when you will go back, or whether we need to transport the project samples to the city." The man explained to Chen Xin why he came to him, and then he looked at Chen Xin with an inquiring look, waiting for his reply.


    Chen Xin was stunned after hearing what he said, and then he reflected that he came to the city to be a rescue team. If he had left all the work in the city, he would have left behind.


    He is not alone now. After he promised to cooperate with the state, there are many things hanging on him. The state has specially set up a special team for him, and many scientific research institutions are affected by him


    It can be said that now Chen Xinzhen is a sneeze can make a lot of people panic, but he is good to die to run to Linshi to be what rescue team!


    This made the person in charge of the special group who knew about it almost raise their blood pressure.


    But they also don''t want Chen Xin to feel that his freedom is limited. After all, Chen Xin''s ability is very important for Yanguo now, that is, Chen Xin has no requirements for the country, otherwise he can enjoy the top treatment.


    So after weighing things up, I decided to send someone to ask. If Chen Xin goes back to work immediately, everyone will be happy. But if he doesn''t want to go back for a while, he can only coax him to send all kinds of project prototypes to the market to let Chen Xin carry out transformation and upgrading, so as not to delay the progress of research and development as much as possible.


    Chen Xin naturally understood what the people in front of him meant, so he nodded and said, "I''m going to stay in Linshi for a while. It''s best if you can send the prototype project to Linshi. However, in Linshi''s current situation, I think you can consider letting people drive from the urban area. It''s very troublesome for the railway to unload the goods.""I understand. I will convey Mr. Chen''s meaning to the superior department for their coordination. As for the way to transport the project prototype to Linshi, I believe the superior department will make reasonable arrangements." The man who came to find Chen Xin seems to be a civil servant, and his speech is a bit of bureaucratic.


    Chen Xin didn''t mind this. He just nodded his head and agreed to it. Then he said to the researchers on one side, "you''re here just in time. I''m working on a project in Linshi. I mentioned to the person in charge before that if it goes well, we can get an effective way to use deep geothermal resources."


    "Deep geothermal resources utilization?" They looked at each other and were curious about what Chen Xin said.


    "It''s not clear how to say that. It''s more intuitive to see it directly with your eyes." Chen Xin couldn''t explain clearly for a moment, so he took them to the site where they were drilling. He pointed to the drilling rig and said to them, "now we are drilling here. My plan is to drill a deep well that can reach the dry hot rock 3000 meters deep underground. By installing equipment at the wellhead, we can extract deep geothermal energy for heating, power generation and other purposes."

 Chapter 357

    "This thing What''s advanced? " Looking at the mechanical parts piled up by Chen Xin, the researchers didn''t feel at all that advanced. They even felt that the heating hub, which has not yet been assembled, is primitive, like something from the steam age.


    Although Steampunk is a very popular element before the disaster, many people like the painting style full of steel, steam, soot and industrialization when they mention science fiction, and like the flavor of living in the heyday of the first industrial revolution in the Victorian era in the 18th century.


    But from a scientific point of view, it''s still a way of using energy that lags far behind waste.


    Although many sci-fi works have injected indescribable black technology into Steampunk, and even let the steam engine drive a fortress to fly, the energy conversion efficiency of the steam engine can be magnified 100 times, the steam source can provide unlimited steam, and artificial intelligence can be developed with the help of the differential engine with paper tape holes


    However, only when the fuel is not fully burned can soot be produced, and only when the waste heat cannot be efficiently used and recycled can a large amount of steam be produced. From the perspective of modern industrial aesthetics, this is undoubtedly a great waste.


    In the eyes of this scientific researcher, this pile of heating hub parts that Chen Xin has devoted a lot of effort to is not as coveted as the electromagnetic metallurgical furnace on one side.


    You know, that metallurgical furnace uses a magnetic field to constrain this technology, which is difficult to reproduce in the laboratory, not to mention keeping the liquid metal magnetic at high temperature and still suspended.


    If we can master the magnetic field confinement technology, we will make great progress in the research of controllable nuclear fusion, making nuclear fusion a new energy source. Isn''t this more efficient and clean than pumping heat?


    But Chen Xin didn''t think so. In the face of the doubts from the scientific researchers, he just shook his head with a smile and said: "it''s not advanced in itself, and there''s nothing to say about the technology of geothermal resources utilization. It''s just pouring water into the ground, using geothermal to heat the water flow, and then pumping it up for heat dissipation.


    However, the heat dissipation efficiency of this thing is very high. According to my design, it can create a heating field with a temperature rise of 50 ¡æ within a radius of 200 meters. If everything goes well, I can use this heating hub to evaporate the snow at the railway station where we are now, instead of relying on manpower to clean it up.


    You have just seen how people in this city load and unload materials. If the railway stations are not cleaned up, the efficiency of loading and unloading materials in this city will be very difficult to improve. "


    "It''s right to say that, but I still feel that it''s a waste to do so. It''s really a waste to heat the air directly..." The researchers tangled about their wording and didn''t know how to say it in order to be polite.


    Chen Xin just took a look at the researcher''s tangle, without too much evaluation, but explained to him: "it''s really a waste to heat the atmosphere directly. If the energy can be used more effectively, it can play a greater role. For example, it''s more efficient to clean up the snow by driving electrical equipment after generating electricity with thermal energy.


    But now Linshi obviously does not have these conditions. We can only rely on this kind of extensive method to clear the snow at the railway station, which will be a waste for the time being. However, after clearing the snow, I will transform this heating hub to provide heat and power for the railway station, so that the heat dissipation will not be so extensive at that time. "


    "It turns out that''s true. Then it''s really feasible." After listening to Chen Xin''s explanation, the scientific researchers thought about it carefully, and found that it was really feasible, and they soon thought that this technology could be applied in other places: "for example, on the construction site, we should first establish such a heating hub, expand the heating field, raise the regional temperature, and make the construction go smoothly. After the construction is completed, we should transform the heating hub into a new one It''s a very feasible technology for building heating and power supply! "


    Hearing what the researchers said, Chen Xin nodded in surprise: "yes, yes! Your idea is more widely used and feasible than I thought before. My original idea was to use the heating hub to build the greenhouse. Now it seems that the application scope of this thing should be more extensive! "


    "Greenhouses? It''s a good idea to build a greenhouse with this! In this way, we can reuse some cultivated land which has been covered by snow! The country is short of food now. If we can resume the use of part of the cultivated land, that''s really good news! " This scientific researcher is obviously not the kind of person who only focuses on scientific research and is indifferent to other things. When Chen Xin mentioned greenhouse, he naturally thought of cultivated land and grain.


    Chen Xin was also interested at this time. He wanted to have a good chat with the professional researchers about the heating hub. He not only projected the design drawing of the heating hub on the snow through the mechanical arm, but also attached the reconstruction drawing and the energy tower drawing. Pointing to the three drawings, he said: "this is the completed heating hub. According to the design, there are two forms One is this kind of heat dissipation mode, which can expand a heating field with a radius of 200 meters, and the other is this kind of energy supply mode, which does not conduct heat dissipation, but converts heat energy into electric energy to supply nearby places in need. ""Is this large heating hub of amplification mode?" The scientific researchers took a look at the two modes of the heating hub and focused on the drawings of the energy tower.


    "This is an energy tower. According to my design, it can exploit deep geothermal resources below 3000 meters, and it can be used with a heating hub." Seeing that scientific researchers are interested in the energy tower, Chen Xin also enthusiastically introduced: "build an energy tower in an area, and then build a heating hub where there is a need. It is connected with the energy tower through pipes, and the energy tower will provide heat energy for the heating hub. In this way, a heating network can be built."


    "Is this for city heating? If we can build a geothermal heating network in the city, that would be great! " The researchers are very much looking forward to this. They have changed their attitude and are very optimistic about Chen Xin''s project.


    However, some of the civilian officials on one side couldn''t get in touch. He only understood what Chen Xin and the researchers talked about. Before he turned the corner, they had changed the topic, which made the civilian official feel a little uncomfortable. So he took advantage of the pause between them and interrupted: "since Mr. Chen has decided to stay in Linshi for the time being, I will go back to reply to the higher authorities Department, but you are studying this project here. Do you need someone to help you? "

 Chapter 358

    In addition to the two people who came to Linshi to find Chen Xin, another rescue team came from the city.


    This is the second batch of rescue teams arriving in Lincheng. Compared with the first batch of rescue teams, their equipment and materials are much more primitive. Most of them only have their own clothes, no protective clothing, and they don''t carry medical tents, but they carry a lot of urgently needed medicines.


    The arrival of these rescue workers made Linshi municipal government overjoyed and rushed them to the rescue station.


    Because they came by train, compared with the first batch of rescue teams, the number of them increased greatly. The arrival of the second batch of rescue teams with 60 people greatly replenished the shortage of personnel in the rescue station, and also made more patients get treatment.


    Chen Xin learned from the scientific research personnel that they first got on the train from the train station in the urban area, took the train to the three towns, and then transferred to Linshi through the coordination and arrangement of the three towns.


    It was the route that Chen Xin discussed when they set out as the first rescue team.


    After the first group of rescue teams opened up the situation in the urban area, the second group of rescue teams were sent out to send people and materials by this relatively time-consuming route.


    "Mr. Chen, if you have anything that needs to be transported from the urban area, you can also transfer it through this line. At that time, you only need to load it together with those project prototypes." After explaining the situation to Chen Xin, the researchers also said that they could deliver something for Chen Xin that he needed.


    Chen Xin doesn''t have much demand for this, but after thinking about it, he said: "I personally don''t have anything to transport. If I can, I hope you can help me get some materials. There is a shortage of materials in the city. I have to go out to collect scrap metal and come back to smelt and make parts again. The efficiency is a little slow. Not to mention the quality of the materials It''s a pass. "


    "It''s easy to say. As long as Mr. Chen needs anything, he can get it for you!" The scientific research personnel are in charge of all kinds of things, and there is no sense of embarrassment.


    However, this is also true. When Chen Xin was in the urban area, he told the scientific research institutions what materials he needed, and they would get them for him.


    "It''s mainly steel. The construction of heating hub needs steel. I''ll write a list for you later. I can send raw materials directly. I can process them here." Chen Xin was not polite when he heard what the researchers said. He was going to make a list later and write down everything he needed.


    While chatting with the researchers, Chen Xin came to the temporary residence of Chen Xin, Cao Daren and the workers, a row of tents buried in the snow.


    This is a tent specially modified by Chen Xin. As for his own RV, he left it at the ambulance station for Qin LAN and Mo Qingyan to live in, but didn''t drive over.


    As for the power supply here, Chen Xin has found several other car batteries. Two new isotope temperature difference batteries have been developed. One is used for his electromagnetic furnace and the other is used for drills. The heating and lighting in the tent are connected to the battery that supplies the electromagnetic furnace.


    Limited by the relationship between raw materials, Chen Xin''s use of electromagnetic furnace is not much.


    Therefore, the power supply in the tent is quite sufficient and stable, and the lighting and heating are guaranteed. Besides the space is a little smaller, it''s very comfortable.


    Chen Xin took off his power armor and put it outside the tent. Then he took the researchers into the tent.


    After picking up a cup and pouring water for the researcher, Chen Xin asked him to sit down.


    However, the space in the tent was limited, and there were no tables and chairs. There was only a small low table for putting things, so they sat directly on the ground.


    "Mr. Chen, do you live here? It looks good! " The researcher looked around the tent and couldn''t help praising it.


    Although the space in the tent is not big, there is no crowd after sitting for two people. The bottom is at least two meters wide. Three or four people can lie down side by side. It''s really good for Chen Xin''s tent.


    "Well, because of the construction here, we have built such a residence here. Besides me, there are workers who also live here." Chen Xin also poured himself a cup of hot water and added a little salt and sugar to it.


    In today''s cold environment, sugar and salt water can effectively supplement the water, electrolyte and energy needed by the body. It is a very good drink.


    "As I have said before about the heating hub, the main thing is that qualified steel is needed as materials. The strength of materials is very worrying because of the waste metal collected." Chen Xin brought the topic to the point of business and told the scientific researchers his current needs: "in addition to materials, what I need is geologists, especially experts in geothermal resources, because both I and the friend who is responsible for drilling wells are lack of knowledge in this field, and professionals are needed to help deal with the whole process of geothermal resources exploitation Possible problems. "


    "I understand. I''ll tell the other side of the city about this and ask them to find a way to send a geothermal expert over." This is a very reasonable request, and the scientific research personnel also know that this kind of thing must be handed over to the professionals, so they frankly agreed.After agreeing to Chen Xin''s request, the researcher also asked Chen Xin about the heating hub and energy tower.


    As for Chen Xin''s previously mentioned building greenhouses with the help of heating hubs and building urban heating networks with energy towers, this is quite attractive to this researcher.


    Although the researcher himself is not engaged in this field of research, he still has full enthusiasm for such things that can improve people''s livelihood.


    If Chen Xin''s ongoing project is completed, this technology can be applied to most areas rich in geothermal resources in Yanguo. When the time comes, energy towers and heating hubs will be built in the city, so that the snow on the surface will melt, the temperature will rise, and people will return to the surface life. It''s not too beautiful!


    "Mr. Chen, you said before that you could build a greenhouse with a heating hub. Are you planning to use the heating hub that is being prepared?" The researcher thought of the greenhouse mentioned by Chen Xin and asked him curiously.


    According to the researcher, the railway station is not a suitable location. After all, there are many buildings around it. If Chen Xin wants to build a greenhouse, he''d better build it on the original farmland.


    After all, the original cultivated land is mature land. Even if it is frozen by snow, it is much better than demolishing abandoned buildings and clearing a piece of ground.


    It''s not only about the amount of construction, but also about the fertility of the soil.


    "I''m not going to put the greenhouses in the city. I''ll drill another geothermal well and build a second heating hub." Chen Xin naturally understood this, so he didn''t have the idea of building greenhouses in the urban area.

 Chapter 359

    The researchers did not go to the city staff to arrange accommodation like the civilian officials who came with him. Instead, they lived directly in Chen Xin.


    Fortunately, there are many tents prepared by Chen Xin here. After a slight adjustment, he made room for the researchers.


    But living in a tent is not as good as living in a shelter. After all, it''s not as good as eating, drinking, pulling, scattering and sleeping before the disaster. Among the five necessities of people, eating, drinking and sleeping in a tent are all easy to solve, but the problem of personal excretion can''t be solved in a tent.


    Even if you don''t dislike the taste, it''s very troublesome to deal with it.


    So under normal circumstances, we all went outside the snow cave where the tent was set up to deal with personal hygiene problems.


    Going to the toilet in this kind of weather, we have to say that it is a very difficult test. Squatting for a little longer is likely to cause frostbite on the buttocks.


    And considering the smell after heating, even if Chen Xin dug another hole near the snow cave to use as a toilet, he could not install a heater to bake his ass.


    This leads to a huge challenge every time you go out to the toilet.


    In addition, bathing is also a uncomfortable thing for everyone, because although the temperature in the tent is not very low, there is no place for people to take a bath. They can only make a basin of hot water, and then wipe their bodies in the tent.


    The action must be fast, otherwise even if there is no wind in the tent, the body will be very cold for a long time, but it will be very troublesome if you catch a cold.


    However, if someone really wants to take a bath, Chen Xin and Cao Daren will not stop them, but will give them half a day off to avoid taking a bath.


    After all, the shelter is in the downtown area. It won''t take long to go back and take a bath.


    Of course, because the drilling work does not start for a few days, none of these workers want to go back to take a bath, and they can tolerate it.


    After all, even if there are bathing facilities in the shelter, it is a luxury to take a bath in the current environment. Generally speaking, it is good for the survivors in the shelter to take a bath once a week.


    The available water resources are quite valuable. Although the country is still maintaining the supply of tap water, in addition to the water to be used for bathing, there is also water to be used for washing clothes. It is precisely in consideration of the consumption of washing clothes that we take a bath once a week.


    Chen Xin didn''t need to think about these problems before. All kinds of living conditions in his refuge are very complete. It''s OK to wash one bath a day, and so are his clothes.


    In addition to worrying about the damage caused by washing too much clothes, Chen Xinzhen has nothing to worry about.


    But now living in a tent like this in a snow cave, many problems that Chen Xin didn''t worry about come out one by one, which makes him have to devote part of his energy to deal with these problems.


    This makes Chen Xin lament that he had a good life before, but at the same time, he can''t help looking at his current environment and thinking about whether there are some places to improve, so that he and others can improve their living conditions.


    Chen Xinke didn''t forget that his own system gained survival points on a large scale by improving the living conditions of others.


    During this period of time, products produced by isotope thermoelectric batteries and exoskeleton protective clothing have been sent to all parts of the country, and Chen Xin has begun to harvest survival points on a large scale.


    Although there is an upper limit, it has to be said that the huge Yan state, such as many refuges, has also brought an astonishing number of survival points to Chen Xin, whose total number of survival points has reached six figures.


    This is a very rich survival. If Chen Xin is willing, he has enough capital to realize many of his ideas.


    For example, Chen Xin has always liked the large-scale mecha, which can''t be built as high as, but the Titan is not necessarily. If Chen Xin really wants to, a Titan in "Titan falls" can still be built.


    Thinking of this, Chen Xin is also ready to move.


    However, he still well controlled his desire. The most important thing now is to build the heating hub, and then build the energy tower.


    As for things like mecha and Titan, it''s not that they can''t be made, but that they should be put back a little.


    After all, other people can''t still struggle on the line of life and death. Chen Xin can enjoy himself and make big robots, can he?


    Although such selfishness is not out of the question, for Chen Xin, he still can not accept such a practice. Moreover, the way the system obtains a large number of survival also determines that Chen Xin needs to help others.


    It''s just that although I can convince myself to restrain some impulsive ideas, I can also convince myself that GAODA and mecha, which are human shaped machines, are very weak, and I don''t need to build such a big toy with high force value


    But thousands of reasons, all kinds of reasons, is always no match for a "big robot, isn''t it fragrant?"


    It''s really fragrant.


    For boys, robots, transformers, up to This kind of large-scale human shaped iron and steel creation always has an irresistible attraction.Otherwise, why are there always boys crying for their parents to buy the handsome toys in the toy store?


    Although Chen Xin said the age when he would cry and want to see something, since he has the ability to build a real one, why should he bear it?


    Even with many reasons to convince himself, Chen Xin still wants to build a robot to play with.


    But when he was considering building robots, he also considered the practicality of this thing and decided to build an engineering mecha first.


    This kind of thing can be said to be of great practical value. In today''s environment, an engineering machine can play a very important role. If it is used well, it can be worth dozens or even hundreds of workers.


    Just like the train loading and unloading work in the city, if there are several engineering machines, the loading and unloading efficiency can be improved several times!


    With this in mind, Chen Xin can''t restrain his inner impulse. With the help of the power armor and the micro-computer on the mechanical arm, he began to conceive his own engineering mecha design.


    Just when he had just designed the skeleton for his engineering mecha, Cao Daren suddenly rushed in from the outside and found Chen Xinchong. He was happy and said in a loud voice: "fight it out! It''s coming out! Writer, here we are


    Cao Daren was so a shout, Chen Xin Leng for a moment to react, quickly asked him: "hit the hot spring?"? Is it really hot spring? "


    "Yes! It''s coming out! It''s really coming out! " Cao Daren was very excited. He pulled Chen Xin to go out, but he didn''t pull the power armor. However, this didn''t affect his excited mood: "the drilling rig drilled more than 400 meters deep, and after penetrating a layer of rock, it met the aquifer, and now it has come out of the water!"

 Chapter 360

    The drill has stopped at this time, and several workers are surrounding the drill to pull out the drill pipe one by one.


    At the same time, steam has been gushing out of the drill hole under the drill, and a hot spring is constantly spraying water upward, making the scene cloudy and foggy.


    Chen Xin and Cao Daren came to the rig and looked at the hot water gushing from the bottom of the well. Chen Xin was surprised and asked Cao Daren, "have you measured the water temperature? What''s the temperature? "


    "The water temperature is over 70 degrees. It''s very hot." Cao Daren is also very excited at this time. He answers to Chen Xin and introduces the situation: "before, after the drill bit broke through 400, I had a premonition that I would come out of the water today, so I paid special attention to it. Sure enough, I met the rock below and began to come out of the water after penetrating it."


    Hearing Cao Daren say that the water temperature is more than 70 degrees, Chen Xin is very happy. High water temperature means rich heat energy. In this way, it can provide more heat, which is very good news for the heating hub.


    However, looking at the gushing hot spring water, Chen Xin also had some worries and asked Cao Daren, "will this water keep gushing? If it is sprayed all the time, will the later construction be affected? "


    "You can rest assured that the water pressure is not high. Now the water is spraying because the aquifer has just been broken. The pressure has a release process, and there is a bit in the casing. The space is relatively small, so the water can be sprayed out. After the bit is pumped out, the water will not be sprayed so much, and it can be blocked by adding a cover." Cao Daren knew this very well and soon explained it to Chen Xin to dispel his doubts.


    At this time, the scientific research personnel also knew the news of drilling out of the hot spring. Looking at the gushing hot spring water, they were excited and asked Chen Xin, "Mr. Chen, I have seen your design drawing. Should the hot water inside the heating hub be recycled? Is it necessary to drill a water injection well? "


    Of course, it''s impossible to pump geothermal resources in this way. Although Hunan Province is rich in groundwater resources, it can''t stand such use.


    Under normal circumstances, the utilization of geothermal resources is carried out through two wells. One well is used to extract groundwater to obtain heat, while the other well is also driven into the groundwater aquifer and connected with the water intake well underground. After the heat is released, the hot water extracted from the water intake well is injected into the ground again through the water injection well to realize recycling.


    "Water injection wells are sure to be drilled, but where and how to drill water injection wells still need the guidance of professionals. This matter is not urgent for the time being." Naturally, Chen Xin knew that he wanted to drill a water injection well, but he was in no hurry.


    The water injection well is not like the water intake well, as long as it is driven into the aquifer and can produce water.


    Because it is to inject the pumped groundwater into the ground again and form a circulation with the water intake well, the location of the water injection well must be in the same aquifer as the water intake well. When positioning, it is also necessary to analyze the trend and geology of the aquifer, the size and area of the aquifer, whether it is permeable or not, and many other factors. It is not a simple matter to drill a hole every few hundred meters.


    This is one of the reasons why Chen Xin said that he needs the help of geologists. This kind of professional analysis really needs real professionals.


    Chen Xin is discussing with scientific researchers about drilling water injection wells, while Cao Daren is more concerned about construction.


    When Cao Daren asked the workers to continue the construction, he asked Chen Xin, "the writer, now the well has been drilled out, what do you want to do next?"


    "Next..." Chen Xin habitually raised his hand to touch his chin, but his hand touched his mask. He had to reluctantly put it down before he said, "next, when the water doesn''t spray, let the workers clear the snow around the well and get ready to build the frame. There''s no need to clear too many places. Dig around the derrick to see the ground, so that it''s convenient to lay the foundation. ¡±


    "are you ready to start building a heating hub?" One side of the researchers heard Chen Xin say, immediately understand what Chen Xin wants to do next.


    Chen Xin nodded his head and answered positively: "yes, clear away the snow, lay the foundation of the heating hub, and set up the scaffold for construction. After that, I just need to assemble and install the parts I have made."


    After learning about Chen Xin''s arrangement, the scientific researchers and Cao Daren did not raise any objection, but Cao Daren still put forward a question to Chen Xin: "writer, after you build this heating hub, are you going to use it to melt the snow? There will certainly be a lot of accumulated water here at that time. In addition, there is no water injection well now. This water intake well will have to continuously pump water at that time. Is the discharge of this water also a problem? "


    "You don''t have to worry about the drainage of the pumped water. I''ll wait until the water injection well is completed and the whole equipment can be operated circularly before starting it. Now I can test the machine at most. In that case, it doesn''t matter if the water is discharged directly." Chen Xin naturally took this into consideration and did not plan to drain the water everywhere.


    However, Cao Daren mentioned that the drainage after snow melting is really a problem that needs to be paid attention to. They dug a well to build the heating hub just in front of the station square of Linshi railway station. However, due to the small size of the railway station, and their own purpose is to clean up the accumulated snow in the railway station, when the heating hub starts, the snow melting is most likely along the railway The gullies where the tracks are running are likely to freeze the railway.This is not a trivial matter. If the track is frozen, it will cause a serious accident of train derailment.


    So drainage must be considered.


    "About drainage How about pumping it away and discharging it to other places? " Cao Daren''s idea is relatively simple, and of course more practical: "anyway, it''s snowy now, and the direct discharge is also instantaneous ice, so it won''t have much impact."


    After hearing Cao Daren''s idea, Chen Xin and the researchers thought that this method was feasible, but they always felt that something was wrong.


    The researchers thought about it and said, "isn''t it good to discharge directly? According to Mr. Chen, the heat supply field generated by the heating hub can cover a radius of 200 meters. If the snow is more than 10 meters thick, it already has the size of a small lake. If so much water is discharged at will, I''m afraid it''s not going to freeze out an iceberg. I think we can find a way to use it. "

 Chapter 361

    How can the accumulated water from melting ice and snow be used? If it''s before the disaster, I''m afraid no one will think about it.


    Although the fresh water resources on blue star have been in a state of relative shortage, generally speaking, in the areas where water resources are not particularly scarce, there is not much restriction on water use, and the snow is mostly allowed to melt and evaporate naturally, so few people will consider recycling snow.


    It''s as if few people would consider recycling rainwater unless it''s in a dry area.


    But now, in order to avoid the formation of ice layer on the railway after snow melting, which will affect railway transportation, Chen Xin must consider the problem of water discharge after he used the heating hub to melt the snow around the railway station.


    It is obviously impossible to let it flow naturally, because natural flow will only flow along the gully where the railway is located, which is exactly what Chen Xin wants to avoid.


    "In other words, can we take away the water and make it into ice bricks to build a house? Don''t we live in a snow cave? Is it OK to build an igloo or something with ice? Isn''t that how Inuit used to live in igloos? " Cao Daren thought of the video he had seen before and the snowhouse of the Inuit living in the Arctic, so he suggested.


    Chen Xin and the researchers looked at each other and shook their heads. In the end, Chen Xin explained to Cao Daren, "the kind of igloos built with regular snow bricks you see are used to cheat tourists. The real Inuit igloo is to dig a hole in the ground and then seal the top with snow bricks, leaving only a small entrance.


    Those neat and beautiful igloos are either artistic works or commercial attractions used to cheat tourists. The real Inuit igloos are no better than the snow caves and tents we live in now. "


    "Well, in that case, can it only be discharged?" Cao Daren was embarrassed when Chen Xin said that, but he still asked Chen Xin how to deal with the snow.


    Chen Xin shook his head, thought about it carefully, and said: "the idea of building a snowhouse is feasible. After that, the snow here will melt, and our tent also needs to be moved. So instead of continuing to dig snow holes, it''s better to use the snow to build a semi submersible snowhouse, which is more comfortable to live in."


    "That''s fine, but we''ll live here later?" Cao Daren is a little strange. The hot spring has come out and the heating hub has been built. Do you still live here after that? Chen Xin doesn''t have a shelter. Even if he doesn''t have a place to live in Linshi, he won''t live in the snow all the time, will he?


    "I don''t live here all the time, but I''ll stay here until the heating hub is running normally and I''m sure there''s no problem." Daren, you can help me finish drilling the well and go home. " Chen Xin recognized Cao Daren''s meaning and didn''t stop him from going home.


    After all, Cao Daren just came to help him. After all, people would go home to live their own life.


    When Cao Daren heard Chen Xin say that, he felt relieved. Although living in a tent in a snow cave is not too hard, he can''t take a bath, and it''s inconvenient to go to the toilet. Compared with the comfortable life in his shelter, there is still a big gap.


    If it wasn''t for Cao Daren, who had been used to living in the open before doing some projects, it would be very difficult for him to live in a good shelter in the current world and run to live in a tent with Chen Xin.


    Seeing that there was no problem with Cao Daren, Chen Xin looked at the scientific researchers and said to him, "now that the construction has started here, please report the matter of asking geologists to help as soon as possible. In addition, please send the materials I need as soon as possible."


    "Don''t worry, I''m going to contact the above. I believe that the next train from the three towns will be able to deliver materials and geological experts." The researcher nodded, did not stay here, but immediately turned to find a place to contact with the higher authorities.


    Watching the researchers leave, Chen Xin doesn''t say anything. He just nods, looks at Cao Daren, and says to him, "we''ve got talent. Let''s arrange workers to start work as soon as possible."


    "Good! When the water can''t be sprayed, I''ll arrange for the workers to start the construction. " Cao Daren nodded, this is his job.


    Sister LAN, please take this patient to the back ward. Thank you A special police officer wearing an exoskeleton is giving Qin LAN a patient who has just finished an operation, asking her to help send him to the ward.


    Qin LAN nodded, took the patient, then walked toward the ward.


    Chen Xin is busy with the heat supply hub. Qin LAN and Mo Qingyan don''t go with him. Instead, they stay at the ambulance station to help.


    Although the ambulance station has been joined by 60 medical staff from the three towns, the shortage of staff has been greatly alleviated, and a total of four medical tents can be equipped with full hands, there are too many patients in the city. Less than 100 medical staff and 50 volunteers are still busy every day.


    However, with the arrival of the second batch of medical staff, the operation of the ambulance station is much smoother, and more patients can be treated every day. At present, the situation has gradually improved.


    As for why Qin LAN and the special police helped to transport the patients, it was mainly because the people in the ambulance station were too busy to come over. They took the initiative to help. After all, Qin LAN has power armor and SWAT has exoskeleton, which is much more convenient than ordinary medical staff who have nothing.After all, the power of power armor and exoskeleton is much stronger than that of ordinary people. If two or three people can transport the exoskeleton, one person can complete the transport.


    Qin LAN sent the patient to the ward, and helped the medical staff put the patient on the bed, which left the ward.


    Although she is only helping, there are many things.


    Fortunately, the staff of the ambulance station can rotate now, and the medical staff also have enough time to rest and eat. There is no overload.


    Qin LAN has been busy, until a medical staff asked her to go to dinner, she found that the meal.


    Together with the medical staff to the temporary canteen, Qin LAN sees Mo Qingyan directing several volunteers to eat for the medical staff, and greets her.


    Mo Qingyan wanted to go to the ward to help, but later found that the logistics side was more suitable for her, so she helped in the canteen side.


    It has to be said that when she was able to run such a large outdoor goods store, Mo Qingyan''s ability is undoubtedly very strong. A canteen is quite orderly under her management.


    "Ah LAN, are you here? There are some vegetables just delivered at noon today. Eat more vitamins! " Mo Qingyan smiles at Qin LAN, but remembers something and asks her, "ah Xin, he''s still busy over there. Didn''t he come back?"

 Chapter 362

    In the evening, when Qin LAN and Mo Qingyan come to find Chen Xin after they are busy with their own affairs, they see that he is still busy.


    The well has not been watered any more, and the workers have removed the drilling rig. Now they are clearing the snow to make room for the construction of the heating hub.


    The workers are cleaning up very fast. At this time, there is a snow pit more than three meters deep on the ground. Relying on his own power armor, Chen Xin is helping the workers lift the snow from the bottom of the pit, so as to facilitate the transportation.


    "Ah Xin!" Qin Lanchong is helping workers to clear the snow out of the snow pit Chen Xin said hello.


    "Ah LAN, long Niang! What are you doing here? " Chen Xin also said hello to them. He dumped a basket of snow on a cart and threw it back into the pit. Then he stopped his work and asked them, "isn''t the ambulance station busy? Why do you come to me when you have time? "


    "It''s OK at the ambulance station. When the second batch of rescue team arrived, they could basically run. After they were busy, they still had time to rest." Qin LAN smiles at Chen Xin and answers his question.


    Looking at the busy workers on the construction site, Mo Qingyan asked Chen Xin curiously, "ingredients, don''t you have a rest so late? It''s hard work! "


    Although it''s always dark and can''t distinguish between day and night, most people still keep their work and rest before the disaster to avoid time confusion because they can''t distinguish between day and night.


    So from the time point of view, it''s already eight or nine o''clock in the evening. It''s time for Chen Xin to finish their day''s work and get ready for a rest, but they are still busy.


    "It''s also good. Today, I''ve been waiting for the hot spring well below to stop spraying water, so I started work late. I''m almost done in the evening. I''ll work another day in the daytime tomorrow, so I can clean up the snow here and start construction the day after tomorrow." Chen Xin explained why he was still working at night.


    However, asked by Mo Qingyan, Chen Xin looked at the time and the depth of the snow pit, considered it for a while, and yelled to the workers, "let''s get here today. Let''s go back and have a good rest. We''ll start work early tomorrow. We''ll try to clear this one day tomorrow and start construction the day after tomorrow."


    "Oh Hearing Chen Xin say that they can have a rest, the workers immediately cheered. Then they stopped their work, sorted out the tools, climbed out of the snow pit and walked towards the tent.


    See workers go to the tent, Chen Xinye and Qin LAN and Mo Qingyan together toward their temporary residence.


    When they arrive at the snow cave, Qin LAN and Mo Qingyan are obviously stunned. Although they know that Chen Xin''s conditions are not so good, and they don''t live in a house, they obviously don''t think that Chen Xin''s experience is just a outdoor experience.


    However, although Qin LAN and Mo Qingyan did not expect that Chen Xin had set up a tent in the snow cave, their reactions were quite different.


    Qin LAN looks at Chen Xinzhi''s tent in the snow cave. Her first reaction is heartache. She instinctively says to Chen Xin, "ah Xin, do you sleep in the tent like this at night? This condition is too hard. Why don''t you go back to sleep in the car at night? No, I can''t. I''ll just ask Han Ping to drive over! "


    "It''s not as hard as you think. There''s a heater in the tent. The temperature is not low." Chen Xinchong Qin LAN smiles. Although she is comfortable with Qin Lan''s care, she doesn''t feel that she is so hard.


    With that, Chen Xin took off his power armor and took two people into the tent.


    The sound insulation of the tent is not very good. The voice of workers outside can be clearly transmitted to Chen Xin''s tent.


    Listening to the noise, Qin LAN can''t help frowning. At the same time, she feels even more sorry for Chen Xin. As Chen Xin''s girlfriend, she knows that Chen Xin hates noise very much, especially when he sleeps, even a little noise can wake him up.


    "The tent is not sound proof. If someone snores at night, won''t it make you sleepless?" Qin LAN looks at Chen Xin and hopes to persuade him to go back to sleep.


    She didn''t have any other purpose, but simply hoped that Chen Xin could sleep better at night.


    "Fortunately, if you have earplugs, you can''t hear them. You can''t put on your driving suit. You can''t hear any sound with your helmet." Chen Xin photographed his driving suit. Theoretically, this suit can be completely isolated from inside and outside. Shielding a little noise is totally trivial.


    Chen Xin didn''t do that, and he just felt a little uncomfortable sleeping in his driving suit.


    Seeing Chen Xin say so, Qin Lan also knows that it''s no use persuading him again, so she has to give up persuading him to go back to the car to sleep, but the look in Chen Xin''s eyes also becomes a little resentful.


    For the resentment in Qin Lan''s eyes, Chen Xin can feel it naturally, but he can''t promise to go back to sleep.


    After all, he also wants to go back to sleep comfortably, but everyone lives in a tent. Chen Xin''s special way to go back to sleep in his own luxury saloon car makes him unable to do such a thing.


    In the past, Chen Xin also felt that sharing weal and woe is a show to buy people''s hearts. But when he really started to work, who was impatient to think so much?For people who really do things, it''s normal to eat and live on the construction site with workers.


    "Since you don''t want to go back, ah Xin, let''s do it first! Do you have anything to eat? " Mo Qingyan pulls Qin LAN, but she is very careless. She looks for food in Chen Xin''s tent. "I remember you said you wanted to go to the Arctic to see how the Inuit live in the igloo. Now it''s a personal experience, isn''t it?"


    "That''s right, but travel experience and living in such an environment are totally different experiences. Long Niang, didn''t you say before that you wanted to experience the ice and snow hotel which only operates in winter? " Facing Mo Qingyan, Chen Xin is half joking, and also joking about what the other party has said before.


    When Mo Qingyan heard Chen Xin say this, she nodded generously: "yes, I really like the ice and snow hotel in northern Europe. It''s said that the rooms are made of ice and snow furniture. Even the bed is covered with snow, but you can sleep in the sleeping bag and only wear underwear. It''s exciting to think about it!"


    Hearing Mo Qingyan''s words, Chen Xin couldn''t help laughing: "if you really want to experience the kind of environment where you only wear underwear and sleep in a few degrees below zero, it''s very easy. Just stay at night. There''s a heater in the tent and the temperature is five or six degrees. Even if you kick the quilt at night, it won''t be frozen."


    Chen Xin''s words were just a joke, but Mo Qingyan didn''t know what was wrong. She nodded her head and said happily, "OK, I won''t go back in the evening!"

 Chapter 363

    Qin LAN hears Mo Qingyan say that she won''t go back at night, and immediately looks at her with sharp eyes. However, seeing Mo Qingyan''s flattering expression behind Chen Xin''s back, she still nods after hesitating for a moment, and doesn''t say anything.


    In fact, they have reached a consensus on some things, but it is not enough to say what this consensus is.


    The only thing I know is that the consensus they reached is a good thing for Chen Xin.


    But Qin LAN didn''t object, but Chen Xin couldn''t help picking an eyebrow. He was just joking, but Mo Qingyan really wanted to stay, which made him say: "do you really want to stay? I''m all old men. You''re a girl. Where do you sleep at night? This tent is occupied. "


    "Can''t I sleep here? You''re the only one in your tent, right? There''s nothing wrong with you sleeping down. " Mo Qingyan said without caring, and at the same time, she lay down, as if trying to find out if Chen Xin''s tent could sleep for two people.


    However, as soon as she lay down, Mo Qingyan had to sit up again. Her exoskeleton didn''t take off, and this lay down obviously pushed her back.


    Chen Xin looks at Mo Qingyan''s performance and turns to Qin LAN for help, but Qin LAN doesn''t seem to see it. She just discusses with Mo Qingyan whether it will be cold to sleep here at night.


    "Oh, it won''t be cold! There are sleeping bags and heaters, and the temperature should be enough. " Mo Qingyan patted her magnificent chest with a indifferent face, pointed to Chen Xin''s sleeping bag and said, "I''ve sold this brand of sleeping bag before, and the quality is very good. Even if the external environment temperature is - 10 ¡æ, you can take off the light in the sleeping bag. And there is a lot of space inside the sleeping bag, even the single version of the sleeping bag can also squeeze in two people, or put the clothes in to warm up, so as not to be frozen when you want to get up. "


    Looking at Mo Qingyan''s appearance and Qin Lan''s inaction, Chen Xin looks at them helplessly. Although he doesn''t know what the two women are going to do, Chen Xin can''t really drive Mo Qingyan away.


    "How do you squeeze two? You girls can squeeze a sleeping bag for two. Anyway, they are petite and men can''t Although Chen Xin has no way to drive Mo Qingyan away directly, he still wants to refuse her to stay: "and I''m just a sleeping bag. Long Niang, you can''t really squeeze a sleeping bag with me, can you?"


    "Why not! In the past, when people went camping, they crowded through a tent, didn''t they? " Mo Qingyan has a indifferent attitude.


    Mo Qingyan''s indifference is pretended, but what she said is true. In the past, when a group of them went camping, the tent was limited, and there were several people crowded in a tent. At that time, there were no men and women.


    But at that time, we all wore a lot of clothes, and a sleeping bag for one person, crowded together, there was no obstacle.


    Chen Xin can''t refute Mo Qingyan''s statement. She shakes her head and leaves the tent to store materials. She finds out two spare sleeping bags and takes them back. After throwing them to Mo Qingyan, it''s her default to stay.


    "Ah LAN, why don''t you stay at night? It happens that the three of us haven''t talked together for a long time." Chen Xin also simply let go at this time. In order to avoid Qin Lan''s blind thinking or misunderstanding with Mo Qingyan, he simply let Qin LAN stay at night.


    When Qin LAN heard Chen Xin say this, she took a look at Mo Qingyan, whose face had become ugly. She couldn''t help laughing and nodded: "well, although we usually live together, we haven''t talked about each other for a long time. It''s good to have a chat and talk from the heart."


    Hearing Qin LAN say so, Mo Qingyan''s face collapsed. Obviously, things have deviated from her original expectation.


    In the evening, the workers outside the tent purr rhythmically. Three sleeping bags inside the tent are laid out and all three of them have shrunk into the sleeping bags.


    Two sets of power armor were put outside the tent. Mo Qingyan also took off her exoskeleton protective clothing. All three of them were wearing only close fitting clothes.


    The temperature in the tent is not low. The heater is working well, providing enough heat for the tent to maintain the temperature at an acceptable level.


    Chen Xin sleeps on the side with Qin LAN in the middle and Mo Qingyan on the other side.


    Originally, according to Mo Qingyan''s plan, she should sleep with Chen Xin, and then use the cold excuse to drill Chen Xin''s sleeping bag at night, and then let some things happen naturally.


    But it is obvious that Chen Xin is very traditional or has a bottom line in some aspects. Qin LAN sleeps among the three, just separating Chen Xin from Mo Qingyan.


    Mo Qingyan also had to give up some preparation for a long time, and finally summoned up the courage to come to the door. She really chatted with Chen Xin and Qin LAN for a long time.


    "Ah Xin, why did you come to the market? Even if there is a "talent" to ask for help, you can actually ignore it, right Mo Qingyan is very curious about this. In her opinion, Chen Xin has already fulfilled his duty by transmitting Cao Daren''s distress information to the municipal government in the urban area. Why come to the city?Do so many things not to say, but also sleep in the tent at night, so hard, this is really let Mo Qingyan feel a little confused.


    It''s not that Mo Qingyan thinks Chen Xin shouldn''t come. She just thinks Chen Xin doesn''t have to work so hard.


    To this question, Chen Xin replied with a smile: "maybe it''s just a kind of self satisfaction. I think I have the ability, so I want to help those who need help."


    Chen Xin''s answer is sincere.


    Before he got the system, Chen Xin was a helpful person, but at that time, he only helped others to do what he could, not like now, which can be described as desperate.


    But with the system and the ability that others can''t, he naturally feels that he should do more.


    This is not a superhero "the greater the ability, the greater the responsibility", but just the old patriarch''s teaching that "if you are poor, you can be alone, and if you are successful, you can help the world at the same time".


    Now Chen Xin can fully meet the standard of "reaching". Naturally, what he is thinking about is how to "help the world at the same time", instead of "being alone" in the past as long as he can ensure a good life.


    For Chen Xin''s answer, neither Mo Qingyan nor Qin LAN felt that there was anything wrong. Since Chen Xin wanted to do so, they naturally had no reason to object.


    However, Qin LAN asked: "what do you plan to do, ah Xin? It''s impossible to stay here all the time, isn''t it? "


    "That''s not true. My plan is..." Chen Xin laughed and explained his plan to them.

 Chapter 364

    Chen Xin''s plan was not complete before he came to the city.


    His ideas and plans came to Linshi, and then gradually had a context and outline, and then gradually improved it into a mature idea.


    In Chen Xin''s plan, the first step is to clean up the railway station, and the second part is to build a heating hub and energy tower, which is what Chen Xin is currently doing.


    Among them, Chen Xin will build a loading and unloading station at the railway station to improve the material loading and unloading efficiency of the railway station, and build a greenhouse using the heating hub to try to grow crops.


    Among these two things, the loading and unloading station of the railway station is very important to the city. After all, it is impossible to always mobilize the labor force of the whole city to unload the trucks. Besides delaying other things, so many people work together. In fact, the efficiency is not high, and everyone''s strength can not be maximized.


    Therefore, a loading and unloading station that can effectively improve the efficiency of material handling is very necessary for the city.


    It''s just like in the construction game, if you don''t build resource buildings, you can''t get enough resources to build other buildings and maintain the operation of the city.


    But these are just the beginning for Chen Xin.


    According to the plan he conceived during this period, what he really wants to achieve is to build a heating network composed of energy towers and heating hubs in Linshi, which he mentioned before.


    At the beginning, Chen Xin''s idea was to upgrade the heat supply hub into an energy tower, and then raise the regional temperature to build a greenhouse. However, after discussing with scientific researchers, Chen Xin found that his idea was not perfect, so after constantly improving his ideas and plans, the idea of heating network came into being.


    If the heating network can be built smoothly, human beings will be able to get rid of the constraints of shelters and return to the ground life, which is of great significance to the whole human beings.


    Not to mention how much energy can be saved by using sunlight to provide light for crops in the future when the dust in the sky falls and sunlight gradually recovers.


    In Chen Xin''s plan, Linshi, as a pilot city of heating network, will build a large-scale energy tower, launch a heating field in the center of the city, and cooperate with several heating hubs to provide heating and power for buildings, so that most people can return to the surface life and resume production.


    In the periphery of the city, a large number of greenhouses are also built by the heating hub for agricultural production.


    In this way, the overall living standard of the neighboring city can be restored to the level before the disaster as much as possible, and the productivity level and food output of the city can be restored to the same level as before the disaster as much as possible.


    We should know that there is a huge gap between the current productivity level of Yanguo and that before the disaster, and the remaining industrial production capacity is not even one tenth of that before the disaster.


    Although the country is now trying to restore production, after a year of construction, it has restored a lot of production capacity, but on the whole there is still a big gap.


    Take the urban area where Chen Xin lives as an example. In the past, the annual output of various chemical products of several large-scale chemical plants and refineries around the urban area was calculated as 100000 tons. However, now these production capacities are all gray, and only a few underground plants in the urban area are preserved. The recovery of the overall production capacity is far away.


    Although the state has put part of industrial production into shelters, many problems in industrial production determine that it is not impossible to put them underground, but there will be many problems.


    Limited by this, coupled with the blizzard that lasted for more than half a month, the overall recovery of the industrial system is slow, which is not difficult to understand.


    If Chen Xin''s conception of energy tower and heating hub is successful, and the heating network can be built smoothly, then the country can take this opportunity to resume industrial production on the ground, and let the country''s post disaster reconstruction enter a new stage.


    Of course, affecting the whole country is the final stage of Chen Xin''s whole plan. At this stage, his purpose is to set up a heating network in Linshi, and take Linshi as a pilot to test how much influence the heating network of "energy tower + heating hub" has on the recovery of urban production and life.


    This plan has been reported to the special group through the scientific research personnel, and has received the attention and support of the senior management of Yanguo.


    All the geologists and related materials Chen Xin needs have been prepared. Together with a batch of engineering construction equipment and newly produced exoskeleton protective clothing, they will be loaded on the truck, waiting for Chen Xin to come.


    On Chen Xin''s side, after chatting with Qin LAN and Mo Qingyan about their ambitions, they talked about some other topics. Seeing that the two ladies were dozing off, Chen Xin reached out and turned off the tent light hanging on the top of the tent and said to them, "go to sleep. You have to get up early tomorrow!"


    Seeing this, Qin LAN and Mo Qingyan say good night to Chen Xin. Then they shrink into their sleeping bags and close their eyes.


    Soon there was only the sound of even breathing in the tent.


    However, after a while, Qin LAN quietly opened her eyes and secretly looked at Chen Xin. Seeing that he was asleep with earplugs on his ears, she carefully turned her head and looked at Mo Qingyan.Sure enough, Mo Qingyan didn''t sleep at all. She opened her eyes when she heard the news.


    "What are we going to do now?" Mo Qingyan asks Qin LAN silently, with a trace of sadness in her eyes.


    Qin LAN looks at Mo Qingyan and looks back at Chen Xin. After thinking about it, she says to Mo Qingyan in the same way: "I''ll drill a Xin''s sleeping bag later. When he''s not ready, I''ll pretend to go to the toilet, and then change you."


    "Can this be done?" Although she wanted to stay for the night on her own initiative, this kind of thing still made Mo Qingyan blush and feel nervous.


    "Yes, as I say." Qin LAN has no feeling that she is pushing her boyfriend out. She confidently tells Mo Qingyan.


    In fact, it''s nothing, but two people sleep in a sleeping bag all night. Qin LAN doesn''t think anything will happen.


    Seeing Qin Lan''s confident appearance, Mo Qingyan also knows that she is on the verge of success. She missed this opportunity. She doesn''t know when she will have a second chance, so she bites her teeth, overcomes her tension and shame, and nods to Qin LAN.


    Seeing that Mo Qingyan agreed, Qin LAN immediately showed a successful bad smile on her face. As she climbed out of her sleeping bag and prepared to get into Chen Xin''s sleeping bag, she imagined how interesting it would be when Chen Xin woke up tomorrow morning and found that someone was wrong.

 Chapter 365

    "What are you doing?" Early in the morning, Qin Lan''s scream directly wakes Chen Xin.


    Chen Xin, awakened by this scream, is a bit confused. He feels that he seems to be holding a person in his arms. He vaguely remembers that Qin LAN got into his sleeping bag last night, but now Qin LAN is talking. Who is in his arms?


    Chen Xin squints his eyes. He doesn''t know the situation. He opens his eyes and looks to the side. Then he sees Qin LAN sleeping in the sleeping bag beside him. He looks at himself angrily and says to Chen Xin: "what are you doing?"


    This makes Chen Xin a little confused. Qin LAN is beside him. What''s in his arms?!


    Chen Xin reacts and looks down in his arms. Sure enough, Mo Qingyan is blushing and shrinks in his arms. She looks up at Chen Xin. It seems that she is shy and buries her face again.


    "Long Niang? Why are you in my sleeping bag? " Chen Xin wants to push people away, but he can''t because of the limited space in his sleeping bag. He quickly moves his hands away from Mo Qingyan.


    Opened the zipper of the sleeping bag, drilled out from the sleeping bag, Chen Xin this just looked to the side of Qin LAN, although in the brain chaos, but also thinking about how this is going on.


    Chen Xin remembers that when she went to bed last night, Qin Lan was sleeping next to her, Mo Qingyan was on the other side of Qin LAN, and the light in the tent was always on, so there was no possibility of climbing the wrong sleeping bag at night.


    And Chen Xin clearly remembered last night that although someone had drilled into his sleeping bag, he clearly felt a cold iron hand at that time. Because Qin Lan''s prosthetic limb was too cold, it made him wake up. It''s impossible to remember wrong.


    But now who is in his sleeping bag has become Mo Qingyan? What happened in the middle of this?


    Although Chen Xin is not clear about the situation, he can be sure that something deliberately happened last night.


    Qin LAN in his arms, if she did not take the initiative to climb out, how can people change into Mo Qingyan? Mo Qingyan didn''t take the initiative to climb into his sleeping bag. How could she get into his sleeping bag from the sleeping bag across from one person?


    How did these two people change places last night?


    It is because of this that Chen Xin suddenly has doubts in his mind.


    When doubts arise, Chen Xin''s confused mood calms down. He takes a look at Mo Qingyan, who is still shrinking in his sleeping bag, and Qin LAN, who is angry with her cold face, suddenly notices a detail.


    Qin LAN, Mo Qingyan and Chen Xin have known each other for many years, and Chen Xin knows their personalities very well.


    Although Mo Qingyan is very straightforward and easy-going, she is like a brother to Chen Xin, but Chen Xin knows that she has always been very traditional and conservative in her emotional problems and the relationship between men and women. Her shyness at this time is a very normal reaction.


    But Qin LAN is different. As a boyfriend who has been with her for a long time, Chen Xin knows very well that if he has any cheating behavior, Qin LAN will blow his head at the first time. It is impossible to ask the question "what are you doing" calmly.


    Chen Xin is particularly concerned about Qin Lan''s hand, which is stretched at this time, but he clearly remembers that as long as Qin LAN is angry, she will unconsciously clench her fist, which she does not know.


    So she''s not really angry? Is it just an act?


    Thinking of this, Chen Xinzhong seems to have realized something and seems to understand it. But at this time, he is still not sure whether his guess is correct, so he plans to cheat them. So he puts away the panic on his face, looks like a sudden realization and calmly does it. Then he seriously asks Qin LAN and Mo Qingyan, "whose idea?"


    As soon as Chen Xin''s words come out, Mo Qingyan''s face suddenly changes from shyness to panic. Qin LAN seems to want to keep angry and says to Chen Xin, "what''s your idea? Ah Xin, you haven''t told me. What''s the matter! Let''s be clear. What''s going on? "


    Hearing what Qin Lan said, Chen Xin had a bottom in his heart. If he had guessed before, now he could be sure that what happened was planned by them.


    Although Chen Xin doesn''t know why Qin LAN and Mo Qingyan do this, he can be sure that Qin Lan''s anger is pretended.


    So Chen Xin felt more relaxed, but still maintained a serious expression on his face and looked at Qin LAN: "what''s the matter? Don''t you know? It was Alan who drilled my sleeping bag last night, right? How can Qingyan come in if you don''t climb out by yourself? And if you were really angry, would you ask me what''s going on? In your character, it''s time for me to eat my fist now. "


    "You mean I have a bad temper!" When Qin LAN heard Chen Xin''s words, she immediately wanted to reach for his collar.


    "You see, that''s what Aran looks like when you''re really angry!" Chen Xin points to Qin LAN and grabs her hand. While pointing out her behavior, he also asks her, "so this is a LAN''s idea?"


    By Chen Xin so point to say oneself, Qin Lan also can''t maintain the angry expression on the face, snorted after this just to Chen Xin ask: "how do you see?"Mo Qingyan is also very embarrassed to climb out of Chen Xin''s sleeping bag and sit upright beside Qin LAN.


    "I know Qing Yan. She won''t take the initiative to do this kind of thing. On the contrary, it''s ah Lan You..." Chen Xin pauses for a moment and takes a deep look around. Qin LAN then continues: "if you can see my embarrassment, you will want to trick me."


    When Chen Xin said that, both Qin LAN and Mo Qingyan''s faces were full of grandeur. They didn''t know what to say.


    Although the incident was carried out according to their expectations, the result was obviously beyond their expectations, especially now it was exposed by Chen Xin, which made both of them fall into a rather embarrassing situation at this time.


    However, Chen Xin obviously has no intention to study the matter in depth. How can he not understand that Mo Qingyan, who has a traditional character, took the initiative to sleep in his arms for a whole night? What does it mean? Her mind has already been made clear.


    Besides, Qin LAN, who is on the other side of the story, has planned the event. Obviously, she is not against Mo Qingyan''s liking for him. They may even have reached some agreement.


    Although it''s a very happy thing to be able to enjoy the happiness of all, Chen Xin didn''t say that he had any resistance to it. He just felt that this scene is not a good time to deal with it.

 Chapter 366

    After what happened in the morning, Chen Xin did not stay in the tent, which only deepened the embarrassment among the three.


    After dressing up and washing up a little, Chen Xin got some food and left the tent. Other workers outside got up one after another and were ready to go to work.


    Mo Qingyan and Qin LAN in the tent watch Chen Xin leave, and their facial expressions are not very good-looking.


    Qin LAN feels embarrassed and sorry for Mo Qingyan because Chen Xin has seen through the incident, while Mo Qingyan is lost and shy. After all, she has taken the initiative, but Chen Xin still doesn''t say anything.


    However, they did not choose to stop Chen Xin and ask him for an explanation. After all, it can still be said that last night was just a joke, and there is still room for things to turn around. If they have to open up and let Chen Xin express his position, in case he refuses, there will be no room for things.


    So Qin LAN and Mo Qingyan, after a long silence, clean up and leave the tent, ready to go back.


    This episode has not had any impact on Chen Xin''s work. Although he may not have expected how pleasant it would be to put Qin LAN and Mo Qingyan in the same bed, he still needs to do his work seriously.


    Yesterday, a snow pit was cleared from the snow near the hot spring well. According to Chen Xin''s estimated project schedule, today, the snow can be cleared and the site needed for construction can be sorted out.


    So after breakfast, Chen Xin and the workers came to the construction site together and continued the work that was not finished yesterday.


    Today''s weather is much better than before. Although it is still very cold and there are occasional strong winds, compared with the time when the snow was several meters deep in a day when the blizzard was raging, it is very good that the workers only dropped a layer of not very thick snow on the tools they put on the site last night to clean up the snow.


    The workers went down to the snow pit, shook off the snow from the tools and went on to dry.


    In fact, these workers don''t know what they are going to do here. Chen Xin just tells them what to do, but they just work.


    As for what to do and what is the significance of doing these things, Chen Xin did not tell the workers all these things, although it may effectively improve work efficiency after telling them.


    As a matter of fact, there is not a big gap between them. As long as there is work to do, even if there is no reason to shovel snow, they will do it seriously. After all, one day''s work will bring one day''s rations. This is something that no one can resist in this world.


    Workers are not slow in clearing snow. Although they are paid by the day, they do not have the idea and performance of cheating on others and delaying the construction period. On the contrary, they work very hard. They do not need supervision or chicken blood.


    Chen Xin fully understands the ideas of these workers. In fact, most of them don''t have the idea of cheating. As long as the daily payment is paid on time, everyone will work hard to do a good job.


    You know, in the current environment, it''s very happy to have a job, eat enough every day and support a family.


    So these workers worked very hard, and the progress of the project was even faster than Chen Xin expected.


    By noon, the snow pit had been cleared, more than two-thirds of the total workload.


    According to this speed, Chen Xin estimated that all the cleaning work should be finished in the afternoon.


    This naturally makes Chen Xin very satisfied. Although the work originally arranged today is only to clean up the snow pit, if the cleaning work can be completed as soon as possible, the time saved will be a good choice, whether it is to let the workers leave work in advance, or to send the prepared parts and materials of the heating hub to the construction site to prepare for tomorrow''s construction.


    Just when Chen Xin was thinking about whether to let the workers go off work early to have a rest and get ready for tomorrow''s work, or to transport the prepared parts and materials from the snow cave first, the staff of Linshi found Chen Xin in a strange car.


    "Hello, is that Mr. Chen? We are from the municipal government. The municipal government knows that you are working here, so let''s come here to express our sympathy. " The staff introduced his identity to Chen Xin, and pointed to his car and said to Chen Xin: "today is new year''s Eve. The municipal government is very grateful for your rescue team coming from the city to help us. I feel very sorry that you can''t go back to the new year and reunite with your relatives, so I specially prepared dumplings for you."


    "It''s new year''s Eve?" Chen Xin looked at the staff with some surprise. Since the meteorite fell, the sky has fallen into a long dark night. He has not paid attention to which day it is for a long time. At most, he just looked at his watch to confirm whether the time is am or PM.


    But it''s new year''s Eve, which Chen Xinzhen didn''t expect.


    Thinking of this, he also made a decision on what he was hesitating about. He said to the staff, "thank you so much. I forgot that today is new year''s Eve! Is the dumpling in the car? Please send it to our place where we can cook it. I''ll let the workers eat it. ""Our car is a field dining car. We can cook it here." Hearing Chen Xin''s words, the staff quickly said that they could cook dumplings directly in their car.


    However, Chen Xin shook his head: "it''s not hidden. Even if it''s cooked, it''s cool when the cold wind blows. There''s a heater in our house. The temperature is a little warmer, so that the workers can eat hot dumplings."


    "Oh, so it is! Then I''ll let the driver drive by. " The staff also responded, quickly nodded and asked the driver to drive to the direction of the snow cave pointed by Chen Xin.


    Chen Xin quickly found Cao Daren and told him about it.


    "Look at my brain, I forgot that today is Chinese New Year!" Cao Daren also patted on the forehead, obviously he also forgot about it.


    However, to be able to eat dumplings is obviously an irresistible temptation for Cao Daren.


    He looked at the time and said to Chen Xin, "writer, if you don''t let the workers go back to eat dumplings first, there will be so much work left. In the afternoon, they will definitely finish their work. Let them go back to eat hot dumplings and come back. In the afternoon, everyone will work harder, finish early, and have a holiday with them in the evening. What do you think?"


    "I think so, too." Chen Xin smiles at Cao Daren.

 Chapter 367

    A steaming dumpling is a long time no see for these workers.


    In the whole year after the disaster, all kinds of difficulties came. Although there was no shortage of food to the point of starvation, people who didn''t work were just starving and had to work if they wanted to eat enough.


    However, even for those who have to work outside every day, the food is just standard shelter food, and everyone has been fed up with it for a long time.


    If you want to eat something different, unless it''s a private shelter like Chen Xin and there are plenty of goods, otherwise, no matter how tired you are, you can only eat the same kind of shelter food.


    So for these workers, I''m afraid the last time they ate dumplings was in the new year before the disaster.


    As a result, this meal of dumplings has an extraordinary catalytic effect on these workers. After eating the dumplings, they become energetic when they work in the afternoon.


    Thanks to the great improvement of the efficiency of the workers, they even finished the work earlier than Chen Xin had expected. They also transported the parts of the heating hub to the construction site and made preparations for the construction.


    Looking at the hard work of the workers, Chen Xin did not leave them behind. Instead, he asked them to go home today to reunite with their families after work.


    Not only that, Chen Xin also asked them to take back some of the unfinished dumplings sent by the staff at noon, which can also be regarded as new year''s welfare. When they go back, they can share them with their families.


    Although these dumplings are filled with vegetables and no meat, they are still a rare delicacy.


    Because it was new year''s day, Cao Daren saw that Chen Xin had let all the workers go, and he himself went home after he told Chen Xin about his crime. After all, he was also a city resident, and his family were all in his own refuge, so he also wanted to go back to spend the new year with his family.


    So only Chen Xin was left at the construction site. After hesitating and hesitating for a while, he simply left the construction site, and no one stayed.


    the staff near the city of the ambulance station also sent dumplings, which made the medical staff who worked hard here have a good meal.


    Originally, the medical staff also planned to give dumplings to the patients in the ward, but both the staff in the city and the patients refused the offer.


    In the eyes of the staff and patients in Lincheng City, these dumplings are given to the medical staff. It represents the gratitude of all the people in Lincheng city to the rescue team who came to help them. They can''t and shouldn''t share the dumplings.


    The medical staff of the rescue team gave way. However, in order to avoid waste, they just accepted the kindness. However, when the canteen was dividing dumplings, they still added a few dumplings to each patient''s lunch, which was regarded as the Spring Festival together.


    Because it is new year''s day, the staff of Linshi municipal government still spend a lot of time to organize and decorate, hoping to have more holiday atmosphere in the first new year after the disaster and dispel the heavy haze.


    It''s just that the conditions are really limited. The staff did their best to get some red paper. Several skillful staff and the medical staff of the rescue team wrote Spring Festival couplets together, cut them into stickers, and pasted them on the door of the medical tent for decoration. It''s a little festive atmosphere.


    Qin LAN and Mo Qingyan are still helping the rescue team in their respective posts today. They also know it''s Chinese new year when they see the staff coming to deliver dumplings near noon.


    This makes them regret. Last night, Chen Xin is afraid that he won''t see them today. In this way, Chen Xin is likely to spend the new year alone.


    Thinking of this, Qin LAN and Mo Qingyan both want to find Chen Xin again. No matter what, they all hope that Chen Xinzhen will not be alone during the Spring Festival.


    However, after a busy day, they made a dumpling in the dining hall at night and were ready to take it to Chen Xin. When they wanted to go back to the RV to find out if there was a heat preservation bucket, they smelled the smell of meat as soon as they got on the bus.


    The two men fixed their eyes on the table and saw that there were several steaming dishes on the table, including not only fresh vegetables, but also a lot of meat. In the middle of these dishes, there was a white casserole, which was covered with a lid. I didn''t know what was in it.


    Qin LAN and Mo Qingyan are very surprised to look at the kitchen of the RV. Sure enough, Chen Xin is frying the dishes in the pot in front of the Liuli counter, emitting a strong aroma.


    "Are you back? Wash your hands and get ready for dinner. Today, for the Chinese new year, I specially stewed duck soup and made a braised chicken. Unfortunately, I didn''t get fish, so I can''t have more than one year. " Chen Xinchong and Chen Xinchong laughed and poured the sauce into the pot to thicken the braised chicken.


    Seeing Chen Xin''s appearance and his familiar movements, Qin LAN and Mo Qingyan feel a little at a loss. They didn''t expect that Chen Xin would come back and cook a table of dishes after such a thing happened in the morning.


    But it''s not the way to be so stunned. Qin Lan''s reaction is faster. He put the dumplings they brought back on the Liuli stage and said to Chen Xin, "let''s bring the dumplings back and eat them in the evening! You should have some dumplings for Chinese New Year"Put it here. I''ll cook it later." Chen Xin nodded and took a look at the dumplings. He said to Qin LAN and Mo Qingyan, "you two wash your hands quickly. I''m almost ready. I can eat it soon."


    Seeing that Chen Xin said so, Qin LAN didn''t say much. She took Mo Qingyan over Chen Xin and went back to their respective cabins to take off their protective clothing. Then she came out and washed her hands in front of the sink of Liuli platform and sat down at the dining table.


    After the two of them sat down, Chen Xin also put the stewed chicken on the table.


    Habitually clean up the Liuli desk, Chen Xin sits at the table in the uneasiness of Qin LAN and Mo Qingyan.


    None of them moved their chopsticks, as if they were waiting for something.


    "Ah Xin, how did you come back?" In the end, Mo Qingyan asked this question.


    "The workers finished the work ahead of time. Thinking that today is Chinese new year, they were given a holiday ahead of time to let them go back for Chinese New Year." Chen Xinchong, Mo Qingyan, smiles and explains to her: "Daren is a local. He also wants to go home for the new year. I''m the only one on the construction site. I still don''t need to stay there, so I came back. I think it''s new year''s day, so I''m going to do something good. I asked Bao Zhen for chicken and duck. "


    "Let''s eat then?" After listening to Chen Xin''s explanation, Qin Lan was relieved to see that Chen Xin did not mention the morning''s business, so she quickly advised Chen Xin to have dinner.


    "Wait for Han Ping. I''ll let him get some wine. He should be back soon." Just as Chen Xin said this, the door opened and Han Ping rushed back with the wine.

 Chapter 368

    A rare new year''s Eve dinner, whether it''s for Chen Xin, Qin LAN and Mo Qingyan, or Han Ping who looks like a meal, can be regarded as precious and memorable.


    Now it''s the end of the world. It''s hard to see a feast of chicken, duck, fish and more than 20 dishes in the past New Year''s Eve dinner. But it''s very rich to have meat and vegetables, chicken and duck.


    In addition, it''s new year''s day. All four of them are away from home. They didn''t celebrate the new year with their relatives. In this special environment, everyone had to drink more.


    Han Ping has enough vigilance, and he used to exercise well when he was a soldier. A few glasses of wine didn''t make him drunk, so after eating, he packed some leftovers and got out of the car with the rest of the wine. He planned to have another drink with the special police he knew in recent days, but also to avoid the three people in the car.


    Although he doesn''t talk much, he still has eyes. He certainly can see the strange atmosphere between Chen Xin, Qin LAN and Mo Qingyan. Now they are all drinking wine. If something happens, doesn''t he want to grow needle eyes?


    After Han Ping gets off the bus, Mo Qingyan and Qin Lan also carry the drunk Chen Xin to his cabin.


    "Ah Xin''s smell of wine has not bathed for so many days. Why don''t we take a bath for him?" Qin LAN looks at Mo Qingyan and suggests to her.


    "Ah? Come back? It was your idea last night. It''s so embarrassing this morning. Do you still come now? Are you not afraid that tomorrow he will be really angry? " Mo Qingyan is not happy to hear that Qin LAN is going to do something again. At the same time, she also shrinks.


    After all, that happened in the morning. Even if she wanted to get back together, she could not make a breakthrough immediately.


    But on Qin Lan''s side, I don''t know if it''s the effect of alcohol. She''s obviously a little too excited at the moment. Mo Qingyan is very familiar with this state. To put it bluntly, she drinks too much wine and goes to the top.


    When she was still running a bar, although she was a member and her bar was a relatively light bar, there were often people who drank too much and took the opportunity to get drunk. Mo Qingyan was very familiar with people in this state.


    Now Qin LAN is no doubt in the strength of wine, want to do some of the same thing as the drunken.


    But I don''t know if Mo Qingyan has drunk too much. After a while of fear, she can''t help but feel unwilling.


    He got into Chen Xin''s bed, but it turned into a farce. How could Mo Qingyan bear it?


    "Well, so what? Anyway, he can''t beat me. If it''s a big deal, he''ll have to bow hard! That''s what I did when I first slept with him. Didn''t he follow me, too? " Qin LAN looks like a hooligan at this time. It''s really hard to imagine that she used to be a calm and serious special police sniper.


    Excited by Qin Lan''s words, Mo Qingyan has no intention to investigate whether Qin Lan''s appearance is the contrast of drinking too much wine, or she usually suppresses her own nature, just stimulated by Qin Lan''s "overlord bows hard".


    So Mo Qingyan nodded, agreed to Qin Lan''s proposal, and extended her hand to Chen Xin''s collar.


    nothing to say all night.


    When Chen Xin wakes up, he opens his eyes and sees the familiar ceiling, which is the cabin of his RV.


    The ceiling is surrounded by dark light strips, which not only provides light for the cabin, but also makes Chen Xin see the situation clearly.


    His arms were pressed down, both left and right sides made him feel heavy, especially his chest was more like two weights.


    Chen Xin lowered his head and pressed a man on his right side. His neat short hair and a black prosthetic limb let Chen Xin know that it was Qin LAN, whether it was the familiar posture or the familiar feeling of Chen Xin''s right hand.


    But Chen Xin sighed helplessly and turned his eyes to the left.


    A cloud of black temples piled up on his chest. His hair was scattered and covered his face. The heavy weight of the part that Chen Xin touched with his left hand, and the situation that he did not consider the second candidate in the car, no matter how slow Chen Xin was, he should know who it was and what it was now.


    Although it''s a man''s dream to support each other, it''s realized when he doesn''t know anything. This is not the result Chen Xin wants.


    Especially last night, I had no memory? I have to be responsible for things I can''t remember in the morning. Isn''t that a bad experience?


    Although Chen Xin didn''t have any irresponsible ideas, he actually had the idea of being responsible for Mo Qingyan yesterday morning, but he really couldn''t say what he was responsible for under the circumstances yesterday. After all, Qin LAN is his woman. It''s not like he''s cheating when he talks about being responsible to another woman?


    Or to put it more appropriately, step on two boats in front of your girlfriend.


    But now the two girls throw themselves in their arms and wash themselves clean in front of them. In addition to trying to experience it again and restore the memory of last night, Chen Xin has decided to be responsible for Mo Qingyan.As for Qin LAN, Chen Xin will certainly live up to her.


    Just sandwiched between two people, Chen Xin still can''t get over the hurdle.


    After all, it''s a man''s dream to support each other. When we really want to do this, we have to face two women who have received monogamous education from childhood to adulthood and have been instilled with the concept of loyalty to marriage. It''s still very difficult for Chen Xin to take this step and cross this barrier.


    However, the reality did not give him much time to think. When he thought about how to speak, Mo Qingyan on his left chest obviously moved.


    Chen Xin can''t help but move her left hand, which is held down by Mo Qingyan. As a result, she doesn''t pull out her hand. Instead, because of her position, she holds the heavy part she touched before.


    ¡°¡­¡­ Let go Mo Qingyan''s voice was like a mosquito, but it was full of shyness.


    Chen Xin quickly released his left hand and moved his arm away from Mo Qingyan.


    And his this move, Qin LAN on the right side was obviously also affected. After turning over his body, he also woke up.


    In particular, Qin LAN conveniently pressed the light switch on her side.


    All of a sudden, the cabin lights up, and Chen Xin sees the two jade bodies in front of him.


    Obviously, no matter he or Qin LAN or Mo Qingyan, he didn''t wear clothes when he went to bed last night.


    "Wow, I didn''t expect you to have such a good figure, Qingyan! It''s a new bargain! " Qin LAN makes fun of Mo Qingyan, and makes her face redder. At the same time, she pats Chen Xin on the chest: "Hey, ah Xin, you don''t want to be silly now, do you?"

 Chapter 369

    Of course, Chen Xin is not an irresponsible person, but under the current situation, he really can''t make any commitment to Mo Qingyan.


    In fact, there is no commitment between him and Mo Qingyan. What he needs to give Mo Qingyan is only the recognition of emotion and the change of relationship, from a good brother to a lover.


    What really matters is how to deal with the relationship between him and the two women in the future.


    Chen Xin never had the experience of associating with two girls at the same time, and never thought that he would sleep in the same bed with Qin LAN and Mo Qingyan at the same time.


    This makes him a little confused about the new relationship between the three at the moment.


    So after saying some comforting words to Mo Qingyan and agreeing to Qin Lan''s unequal treaties, Chen Xin fled his RV with some embarrassment and returned to the construction site.


    For Chen Xin''s escape, Qin LAN and Mo Qingyan are a little angry. After all, no woman would want a man to run away on the first day of the relationship.


    However, they are also magnanimous to show understanding, willing to give Chen Xin, but also to give themselves some time to adapt to the changes in the relationship between the three.


    To be honest, for Qin LAN and Mo Qingyan, it does take time to adapt to the changes in their relationship.


    After all, even if Qin LAN has already reached an agreement with Mo Qingyan, their previous relationship is also very good, but neither Chen Xin nor Qin LAN and Mo Qingyan ever imagined that their relationship would become like this.


    So it''s not just Chen Xin who needs time to adapt and adjust, it''s the same with them.


    After returning to the construction site, Chen Xin quickly put his energy back to work. Although he has just experienced the changes that have had a significant impact on his life, his work still needs to be completed seriously.


    The workers who went home for the New Year holiday yesterday have already returned to the construction site early in the morning, and they are working energetically at this time.


    Chen Xin put on his power armor and went down to the bottom of the snow pit. At this time, the workers were tearing down the exposed concrete floor under the ground, preparing to lay a foundation for the heating hub.


    The whole heating hub is more than 10 meters high, which is almost equivalent to a four or five story building. A complete set of evaporative heat dissipation devices will be installed inside, making the completed heating hub look like an iron tower.


    Of course, the current heating hub is just a pile of parts that have not yet been assembled. Workers need to assemble them bit by bit after laying the foundation.


    Chen Xin, who went down to the bottom of the snow pit, saw that the workers were hitting the cement on the ground with air picks, but the effect was not good, and the construction progress was not ideal.


    Chen Xinzao had expected that after all, the low temperature of tens of degrees below zero has already frozen the ground hard. Even the ice layer formed by the nearby snow is as hard as granite. It is not easy to drill through the already hard cement ground and make enough holes on the ground to serve as the foundation of the heating hub.


    However, Chen Xin obviously won''t just watch the workers spend time and effort slowly smashing the floor. Chen Xin, with power armor, can easily break the cement on the ground and make holes that meet the requirements of the design drawings.


    "Get out of the way, let me do it." Chen Xin told the workers to stop their work and move out of the way. Then he squatted down and controlled the mechanical arm to the position where the workers had just broken it with the air pick.


    It was just hit by the workers with a pneumatic pick, but there were only a few white spots on the ground, and there was no sign of rupture.


    Obviously, the freezing brought by the cold makes the already solid cement more solid and hard to break through.


    But it didn''t work in front of Chen Xin''s mechanical arm. With all kinds of tools on the mechanical arm working together, Chen Xin soon cut a piece of cement directly from the ground.


    Although the cement is very hard and cannot be broken by air pick, it does not mean that it can resist the cutting of cutting machine.


    After cutting the cement, it doesn''t mean that the work becomes easier, but it''s relatively less difficult to deal with.


    Because under the cement is gravel and soil. These are the foundations filled in the past when the square was built, and they were pressed by the road roller. While ensuring the smoothness of the ground, the soil and gravel under them were pressed more tightly.


    If this is the case, it will be over for the workers to dig with hoes. However, the cold and low temperature turns the soil into frozen soil, which can not be dug casually by manpower.


    In fact, Chen Xin asked the workers to have a try. Even if he used the air pick, he just made a small pit on the gravel and frozen soil. Although it was not useless, it would take a long time for Chen Xin to use the air pick to make the foundation he needed on the ground.


    In the face of this situation, Chen Xin can only continue to wave his mechanical arm.


    So, in the eyes of the workers, Chen Xin''s mechanical arm is nearly ten times faster than them, and has made all the foundations needed for the construction of the heating hub on the ground."Well, the foundation has been finished, and the next construction is up to you." Chen Xin got up from the ground and felt that his waist was a little sour, so he told the workers to continue the construction, and then he climbed out of the snow pit.


    Although the workers are very surprised at the efficiency of Chen Xin''s power armor, they can only envy it. When it''s their turn to work, they still have to use their hard-working hands.


    According to Chen Xin''s requirements on the drawings, several main support columns of the heating hub are embedded in the foundation just laid. Other supports are assembled according to the drawings. After the main support columns are fixed and kept horizontal and vertical, the water mud is poured into the foundation.


    Of course, the cement used by the workers is no longer the ordinary cement in the past. Although that kind of cement is not unusable, the temperature must be raised to above zero. For Chen Xin, they do not have such construction conditions for the time being.


    So they use antifreeze cement with antifreeze agent and water reducing agent to ensure that the cement will not freeze because of the water setting too fast in the process of use, resulting in cavities and other phenomena in the cement.


    These workers are skilled workers, so there is no problem in this step, all the support columns are very smooth in accordance with the construction requirements to complete the cement pouring.


    And because the weather is too cold, the cement has soon frozen as hard as stone, firmly fixed the support column of the heating hub on the ground.

    Taking several supporting pillars as the longitude and ten rings as the latitude, a cylinder composed of grids quickly stood in the snow pit.


    This is the main structure of the heat supply hub. All the rings are nested on the support columns and connected with the support points by welding and bolts. The whole structure is quite stable. Even if Chen Xin pushed it twice with power armor, there was no shaking.


    The stability of the main support frame also means that the subsequent construction has a good foundation.


    The support and cross plate were placed on the wall of the main support frame and the snow pit. The workers started the two-stage construction. The main support frame was installed with evaporative cooling device, and the relevant pipes were installed.


    There are four stages in the whole installation work, and the remaining two stages are the installation of the outer heat sink and the overall assembly.


    Compared with drilling and snow clearing, the whole installation work is relatively simple. According to the original construction plan, workers can complete all the installation work in two days.


    However, thanks to the high morale of the workers, these energetic workers have advanced the construction period a lot. According to the current construction schedule, the whole construction period has been almost half a day ahead of schedule, and the whole construction period has been shortened by 30%, which is quite gratifying.


    However, compared with the gratifying progress of the construction period, Chen Xin is worried about whether another thing will delay time.


    That''s about the location of the return well.


    Obviously, this return well can''t be drilled anywhere. As for the reason, we have already said that the construction of the return well can''t be started before the geological experts arrive.


    So Chen Xin is very worried now. It is very likely that the pumping well on this side has been completed, the heating hub has been put into operation, and the return well on that side has not yet been selected.


    In that case, unless Chen Xin decides to directly discharge the recyclable hot spring water from the pumping well, it will inevitably delay the construction period.


    Fortunately, Chen Xin''s worry did not come true. As workers were installing several core components of the steam cooling device on the main support frame, another train drove into the Linshi railway station.


    besides the relevant relief materials allocated by the state after knowing the situation in the city, the train also supplies materials and materials for Chen Xinyun, and the most important geological expert.


    What''s more, it''s not just a geological expert, but a geological exploration team composed of several geological experts.


    "Are you Comrade Chen Xin? Hello Hello! I''m from the Geological Bureau of Hunan Province. My name is Zhang. You can just call me Lao Zhang. " A white haired old man held Chen Xin''s palm in his powerful hands and warmly said hello to him: "these are my colleagues. According to the instructions of the superior, we will cooperate with your work. If you need anything, just tell me."


    The old man, who calls himself Lao Zhang, is obviously nearly eighty years old, but he is very healthy. Even if he is wearing protective clothing, Chen Xin can feel the spirit of the old man and his fighting spirit.


    Chen Xin was a little surprised at the age of Lao Zhang, but he was not surprised at the age of the old man when he thought that it would take time to study, and geological work would require a lot of time to collect geological data in the field.


    As for the other members of the geological exploration team who came with Lao Zhang, they are younger, but this is only relative to Lao Zhang. In addition to two young people who should be college students, the remaining three members of the team are all in their 40s.


    Through Lao Zhang''s introduction, Chen Xin learned that these three middle-aged people were all Lao Zhang''s students. After graduating from University, they were engaged in geological work. They have worked with Lao Zhang for more than 20 years. They have become middle-aged uncles from the same youth as those two college students.


    Looking at these geological experts, Chen Xin deeply felt what it means to devote his life to his career.


    Chen Xin didn''t show too much courtesy to several geological experts. After greeting them and introducing himself, Chen Xin directly projected the design drawing of the heating hub with the mechanical arm of the power armor and explained to several people: "this device is a device that uses the hydrothermal geothermal resources with a burial depth of about 400-800 meters to obtain heat energy. Its main work is as follows The principle is to pump the geothermal hot spring water whose temperature is much higher than the ambient temperature, and radiate the heat through the evaporation and heat dissipation device.


    Although it is not impossible for the device to operate independently, the direct extraction of underground hot spring water is undoubtedly a great waste of underground water resources and geothermal resources, and it will also affect the stability of underground geological structure. Therefore, it is necessary to drill a return well in the same aquifer to inject the hot spring water pumped up and cooled into the ground again.


    Due to our lack of relevant geological knowledge and relevant data, we have no way to determine where the backwater well should be drilled, so we need Professor Zhang''s assistance to help us locate the distribution and direction of the aquifer we are drilling, and determine the location of the backwater well, so that we can start the construction of the backwater well as soon as possible ¡£¡±


    "Your equipment is very convenient! If we had this equipment when we were engaged in geological work, we would not have to carry a lot of heavy and space occupying drawings with us. Now the technology is really advanced! " Lao Zhang sighed, nodded to Chen Xin and said, "I have understood the situation. Before I came here, the superior department also told me the relevant situation. So I have brought all the geothermal resources exploration data of Hunan Province in recent years. Through these data, we only need to carry out on-the-spot investigation to determine the aquifer distribution and backwater wells that Chen Xin needs It''s the right place to work. "Lao Zhang should have formed the habit of vigorous and resolute work in the past years. While talking with Chen Xin, he asked two young college students to open their luggage, take out relevant maps from them and spread them out in front of Chen Xin.


    Mr. Zhang pointed to the diagram above and said to Chen Xin, "Comrade Chen Xin, look here. This is the mountainous area where Linshi is located. This mountainous area is a fractured zone. In fact, geothermal resources here are very rich and dense.


    You are now drilling a well in a geothermal layer covering the whole city. The underground thermal energy reserves are quite rich. If you can effectively use it, that would be great! "


    Lao Zhang''s expression is full of a kind of positive fighting spirit. Even though his eyebrows are white, he is far more energetic than the young college students who are responsible for moving things.


    After explaining the relevant situation to Chen Xin, two young college students were left to settle the luggage and build their houses, while he, three of his students and one of Chen Xin''s staff in the city set out with the necessary exploration instruments.

 Chapter 371

    The group of geologists who came to support Chen Xin did not live up to his expectations, nor did they break their promise.


    Professor Zhang and his three students, accompanied by the staff of the city, spent about half a day to determine the location of the return well.


    "The aquifer is widely distributed, with the railway station as the middle point, the seventh middle school in the northwest and the hospital in the southeast. It can be said that the area is still very wide." Professor Zhang spread out a map in front of Chen Xin, on which he marked in detail the distribution range of the aquifer where the well they had dug in the square of the railway station.


    Chen Xin looks at the map carefully. Although he doesn''t know much about geology, he can still see the area marked by Lao Zhang with colored pencil.


    Looking at the area covered by the colored shadow on the map, including the original shopping mall where the ambulance station is located, he pointed this point on the map with his finger and asked Professor Zhang, "Professor Zhang, this shopping mall is a refuge in the city. The rescue team from the city has also built an ambulance station here. Is this a suitable backwater point? If the return well is drilled here, is that ok? "


    "Here?" Professor Zhang looked at the position pointed out by Chen Xin on the map, thought about it carefully, and replied: "it''s still within the range of aquifer, and the distribution of rock strata is relatively uniform, so it''s no problem to drill wells."


    Professor Zhang''s words made Chen Xin happy. If a well could be drilled at the location of the ambulance station, he could drill the location of the return well next to the ambulance station, and build the heating hub supporting the return well here to supply heat and power for the ambulance station and underground shelters.


    This is very useful and effective to help the survivors of the disaster.


    Although Professor Zhang doesn''t have a deep understanding of Chen Xin''s plan, he also knows the impact and role of the completion of the heating hub. He also hopes that every heating hub can play the greatest role and be built in the position where it can play the greatest role.


    In addition to the fact that more than one wellhead location was selected during the previous exploration, he added to Chen Xin, "in fact, in addition to this point, the seventh middle school and Xiangbei hospital in Linshi can drill wells to build the heating hub you designed."


    "Seventh middle school? Xiangbei hospital Chen Xin looked at the two points on the map, looked at them carefully, asked Professor Zhang, "Professor Zhang, can these two points also be used to drill wells? Is that a return well or a discharge well? "


    Facing Chen Xin''s inquiry, Professor Zhang pointed to the location of Linshi No.7 Middle School on the map and said to Chen Xin: "Linshi No.7 Middle School is located at the foot of the mountain. The terrain is higher than that of the railway station square. It''s surrounded by the original farmland. It''s appropriate to drill the backwater well here. Moreover, it''s not far from the railway station square. It can cooperate with your current well Get up.


    As for the Xiangbei hospital, there is basically no big difference between the terrain and the shopping mall where the shelter and the ambulance station are located, so no matter which is the return well or which is the outlet well, the impact is not big. If you have to distinguish, I suggest you set the return well in the shopping mall. After all, according to what you say, the demand for heating there should be higher. "


    "Since Professor Zhang has said so, let''s follow your advice. You are the expert in geological matters. I''ll listen to you." Chen Xin follows the advice of Professor Zhang and determines the next plan.


    See Chen Xin has determined the next construction plan, Professor Zhang immediately feel completed a task.


    Just happy to finish the task, Professor Zhang asked Chen Xin with concern: "Comrade Chen Xin, are there only four heating hubs in your plan? What about the rest of the city? How do you arrange it? "


    "Other places?" Chen Xin was stunned for a moment, but quickly responded and replied to Professor Zhang: "I''m not very clear about the situation in other places. The well here in the railway station square was drilled because it was necessary to clean up the railway station. Without geological exploration, the site was selected and a well was directly drilled here.


    In other words, Professor Zhang, you are here before we can properly select the site. But now we only survey this aquifer. There are only four places that can build heating hubs in the area covered by it. Other places near the city are not on this aquifer. Even if I want to build heating hubs in other places, you need to survey the distribution of underground geothermal resources first There''s a point in view


    Hearing Chen Xin say so, Professor Zhang seems to have prepared to take out another map and spread it out in front of Chen Xin. He said with a smile: "little comrades are careless in their work! How can other places forget? This is a map drawn by the Provincial Geological Bureau when it searched the geothermal resources of the whole province. Although it is an old thing, its geographical location has not changed in general.


    Comrade Chen Xin turns on your projection instrument and projects the current map of Linshi on it. Then you can know whether there are geothermal resources in the important position of Linshi. By comparing the two, you can know whether the heating hub can be built. "


    Professor Zhang''s hand obviously shocked Chen Xin, he was surprised to pick eyebrows, smoothly in accordance with Professor Zhang''s request to open the projection equipment on the power armor, in front of this map projected the city''s urban map, and the two were proofread, so that it combined."That''s very clear! Comrade Chen Xin, look at this. This is the municipal government and the first people''s Hospital in the city. This location is just on the aquifer underground! This aquifer, I remember, is a sulfur hot spring below, which is not up to the standard of medical hot spring and has no tourism development value, but the water temperature is more than 60 degrees. Should it be enough to meet your heating hub? " Professor Zhang looked at the map and asked Chen Xin happily.


    Chen Xin also nodded and pointed to the map: "not only the temporary municipal government and the first people''s Hospital, but also the sixth middle school, the second people''s Hospital and the first middle school in Linshi. These places can be used to build heating hubs. Moreover, there are just a few shelters planned by Linshi. If the heating hubs are built, they can be covered These are the refuges


    With that, Chen Xin adjusted the projection and projected the location of several shelters in Linshi onto the map.


    Looking at the location of the refuges projected on the map, Professor Zhang nodded excitedly and said to Chen Xin happily, "in this way, more than half of the refuges in Linshi are covered by the heating hub!"

    Now that the location of the well has been chosen, Cao Daren''s drilling rig is naturally used again.


    He took Chen Xin''s workers to Linshi No.7 Middle School to prepare for the drilling of the return well, while Chen Xin continued to complete the installation and commissioning of the heating hub with the rest of the workers.


    Because the two groups of people have to work separately, Cao Daren''s group needs to rebuild a stronghold on the side of the seventh middle school to settle their tents.


    This also makes the first thing they do after they go to the seventh middle school is to dig a hole in the snow.


    In the original snow cave on the side of the railway station, the space left by Cao Daren and his group of workers after they left was not wasted. Professor Zhang took the members of the geological exploration team to live in, and helped to improve the snow cave, making it more comfortable to live in.


    For those who are engaged in geological exploration in the field all the year round, they live in tents for a long time than they live in houses.


    The years of trekking through mountains and rivers have made these geologists lose their scholarly spirit. On the contrary, they have accumulated a lot of field survival experience, and everyone can be called a master of field survival.


    In Professor Zhang''s opinion, the living conditions of snow cave tents are not much worse than when they were in the wild, and in many aspects they are even better.


    "It''s much better than when I just started working! At that time, I was just in my twenties. A young boy who had just graduated from school went to Wulingyuan with the geological team to do surveying and mapping. At that time, there was no tent. We just built a shelter with branches and leaves and spent a whole month outdoors During lunch time, Professor Zhang was holding a very old aluminum lunch box. While eating lunch, he told Chen Xin about his experience in his youth: "it''s like now, tents, sleeping bags and ponchos are so well equipped! It was amazing that we had a rubber raincoat at that time


    Listening to Professor Zhang''s story, Chen Xin was quite touched.


    At the age of Professor Zhang, when he was a young man in his twenties, it was the most turbulent time in the country. At that time, he was still able to endure the harsh conditions to engage in geological research rather than sports, which was very rare in those years.


    "Professor, why do you use this old lunch box all the time? Now the weather is so bad, this kind of old metal lunch box will soon be cold, and it''s very inconvenient to use. I''d better get a new lunch box for Professor! " Chen Xin noticed the lunch box in Professor Zhang''s hand. Although he didn''t know why he used such an old lunch box, Chen Xin still wanted to give him a lunch box that could at least keep warm.


    However, Professor Zhang shook his head and refused Chen Xin''s kindness with a smile: "no, this lunch box has been with me all my life. There''s no need to change this old man when I''m old, and this lunch box is of great significance to me."


    Professor Zhang''s words let Chen Xin pick eyebrows, but did not say anything more about it.


    "Professor, how about the distribution of dry hot rock resources in Linshi?" Chen Xin turned the topic to his work and asked him another question he was most concerned about at this time.


    Compared with the heat supply hub using water and heat resources, what Chen Xin really wants is an energy tower that can exploit deep geothermal resources. After all, an energy tower is more powerful than a heat supply hub in terms of power and efficiency.


    But what the power tower needs is to drill a hole thousands of meters deep underground, not just hundreds of meters deep.


    No matter the total amount of construction or the technical difficulty, they are totally different.


    "The terrain of Linshi area is typical of two mountains and one gully, the terrain is high in the South and low in the north. Although the whole city is east-west, it is still a north-south geological fault from the overall terrain. The main geothermal resources of Hunan Province are distributed in this fault zone." While eating, Professor Zhang explained to Chen Xin the topography and the distribution of geothermal resources in Linshi: "on this fault zone, there are major reserves of dry hot rock resources in Hunan Province.


    Because of the formation of geological faults, it is relatively easy to exploit the shallow and middle geothermal resources in this area. Many of them even form hot springs and gush out of the surface. However, due to the formation of geological faults, the geological structure in this area is relatively complex. If we want to exploit the deep geothermal resources, drilling will be a huge challenge. "


    Chen Xin''s heart sank when he heard Professor Zhang say so.


    The implication of Professor Zhang is very simple. Let Chen Xin concentrate on the development of shallow and middle geothermal resources first, and think twice about the deep underground resources.


    Chen Xin naturally listened to Professor Zhang''s suggestion, but he didn''t give up his idea on the development of deep geothermal resources, instead, he considered it more carefully.


    "Even if it''s a challenge, now we have to face it." Chen Xin''s tone is a bit heavy, but he is also very firm. He asked Professor Zhang, "Professor, if we want to exploit deep geothermal resources in Linshi, what problems do we need to face?"


    "That''s too much. First of all, you have to solve the problem of drilling rig." Professor Zhang put down his spoon and pointed out the biggest difficulty: "if you want to exploit deep geothermal resources, you must have a professional drilling rig. Your friend''s drilling rig not only does not have enough depth, but also has a very limited diameter. It''s possible to exploit shallow and middle geothermal resources like now, but if you want to continue to dig deeper, it''s not so difficult It''s easy.The geological structure of Hunan Province is very complex. If you drill down with this bit, you can hit anything. It''s OK to say that the rock strata are drilled slowly. But if you hit other geological strata, it''s very troublesome. If you don''t have rich experience, it''s very difficult to deal with all kinds of problems in the drilling process. "


    "You don''t have to worry about the rig. I''ll solve it." Among the problems pointed out by Professor Zhang, what Chen Xin is not worried about most is the problem of drilling rig, which can be solved only by upgrading once.


    However, the complicated geological problems mentioned by Professor Zhang can not be solved by Chen Xin. After all, no matter how he upgrades, it is nothing more than improving the bit, which cannot affect the formation itself.


    Unless Chen Xin is able to produce a giant laser drill or a planetary miner to directly cut the strata for mining, the drill will have to face the competition between the drill bit and different strata.


    As for the laser drill and planet miner, this is obviously not something Chen Xin should consider now. In his spare time, he might as well build a world engine to directly transform the earth''s environment.

 Chapter 373

    Because all the parts have been prefabricated in advance, workers only need to assemble them, so the construction of the heating hub does not take too much time.


    Taking into account the time of laying the foundation, we finished all the work in just two days.


    After the installation of the heating hub, Chen Xin originally planned to connect the pipes on both sides and start the heating hub after the water return well on the side of the seventh middle school was also completed.


    After all, in addition to the problem of drainage, there is also the danger that a large amount of groundwater extraction may cause rock cavity and collapse. In today''s situation that it is difficult to replenish groundwater naturally, we should avoid excessive groundwater extraction as far as possible.


    However, after consulting Professor Zhang for relevant knowledge, Chen Xin put down this concern.


    It is true that a large amount of groundwater extraction will cause underground rock cavity, but it will take a long time and continue to extract a large amount of groundwater. If the amount of groundwater extraction is small in a short time, the impact is not big.


    Because the geological collapse caused by groundwater extraction mostly occurs in the areas where groundwater is extracted on a large scale all the year round. The uncontrolled use of groundwater in those areas, coupled with the relatively poor water resources, the precipitation is not rich enough, and the groundwater is extracted for a long time and can not be supplemented, which will form the underground cavity and cause the geological collapse.


    As long as it is not a large number and a long time of extraction, it will not cause such serious consequences.


    Moreover, although the geological structure of Linshi is complex, it is relatively stable, and there has been no geological disaster such as earthquake or collapse for many years.


    In this case, Chen Xin did not hesitate to start the heating hub.


    With the operation of the heating hub, the underground hot spring water is pumped up with abundant heat energy, and the heat is emitted by the evaporation and heat dissipation equipment, and then it becomes cold water to be discharged.


    According to the design, the cold water should be piped to the return well and then re injected into the ground.


    But since the construction of the return well has not been completed, the cold water can only be discharged naturally.


    Chen Xin''s worry that the water would flow along the railway did not happen. Affected by the high terrain in the South and low terrain in the north of Linshi, the water was drained to the south of the railway station by workers through pipes.


    The south of the railway station used to be the family area of the railway station staff. It is only separated from the railway station by a wall, and can be reached by crossing the railway.


    Further south, there are wasteland and a pool. This is a relatively low-lying area near the city. Although there is a lot of snow cover, the terrain has slightly increased, but if the altitude is measured, it is still a low-lying area.


    So after using a water pipe to stand on the gully above the railway and guiding the water pipe across the railway, you can safely and boldly discharge it here.


    It is not only the cold water after heat dissipation, but also the accumulated water after snow melting.


    However, the situation of water accumulation is not particularly serious, because the heating hub emits heat to melt the snow. At the same time, the environmental temperature also affects the snow melting, which leads to the snow melting speed is not very fast.


    Just standing next to the snow pit, watching the heat wave from the heating hub at work, melting the surrounding snow a little bit, and at the same time rising white "steam", it really makes people feel the beauty of heavy industry in the steam age.


    The reason why "steam" is produced is not that the temperature is too high, which makes the melting ice and snow directly turn into white steam, but that when the snow melts, part of the water vapor evaporates into the air. After leaving the influence range of the heating field of the heating hub, these small water droplets condense rapidly and become small ice crystals.


    Small ice crystals are too small and light to fall to the ground. Driven by the air flow, they rise into the air and naturally become white "steam".


    Chen Xin reached out to wipe the water vapor from his helmet. Looking at the melting snow, he finally showed a satisfied smile on his face.


    The speed at which the heating hub melts snow is certainly not as fast as the speed at which the snow evaporates as soon as the heating equipment is turned on in the ice age game. However, watching the snow melt into water at the speed visible to the naked eye, flow and fall at the bottom of the snow pit, and then be pumped away after it becomes stagnant water can still give Chen Xin a very strong sense of satisfaction.


    This is what he made, in this era will be warm back to the earth, although it is only a small place, still proud.


    Chen Xin walked down the bottom of the snow pit, where the water has gone beyond the feet of the power armor, but Chen Xin didn''t care.


    Because this is for the convenience of the pump pumping, will let it accumulate so much, otherwise the water is too shallow, the pump can not absorb water also trouble.


    Through the environmental monitoring of the power armor, Chen Xin can clearly know that the temperature around the heating hub has reached 27 ¡æ. However, because the snow around the heating hub is more than 10 meters high, almost equal to that of the heating hub, at present, the only area covered by the heating site is the snow pit, which does not reach the radius of 200 meters in Chen Xin''s design.


    However, with the continuous melting of snow, the snow pit has begun to become wide at the top and narrow at the bottom. As long as it continues, it will become a big trumpet, like the shape of a sea bowl.Looking at the booming heating hub in front of him, Chen Xin thought about it, opened the lock of the power armor, came out of the power armor, and took off his helmet.


    Warm and rich in water vapor, let Chen Xin can''t help but take a deep breath, let the moist air along the nose into the body, full of his chest.


    I haven''t seen you for a long time!


    This kind of feeling of standing outside and breathing warm air freely!


    With a long breath, Chen Xin looked up at the tower like heating hub in front of him.


    Thanks to it, the air around here is warm and humid, just like the feeling of the past summer.


    Compared with the slightly dry and cold air in the shelter, the air quality here is not as good as it can be, but the feeling is quite different.


    Just standing outside and being able to breathe warm and humid air is enough to make people excited.


    After all, now the whole earth is a huge ice and snow hell. It''s very rare to be able to stand outside and breathe warm air freely, which has been a long time since.


    Feeling this kind of thing, which used to be common in the past but has become very rare now, Chen Xin shakes his head slightly and has a firm belief in promoting it.


    Chen Xin believes that relying on these heating hubs and planned energy towers, he will be able to do so in his lifetime.

 Chapter 374

    The operation of heating hub has undoubtedly injected new hope and vitality into Linshi.


    Although there is only one heating hub in operation, the other is still drilling wells, and the heating hub in operation has not played a very brilliant performance, standing next to the snow pit and looking at the melting snow, no matter who it is, there is a feeling that hope is gradually rising.


    However, Chen Xin did not allow many people to get close to the heating hub, and even standing next to the snow pit was forbidden, because as the temperature rose and the snow gradually melted, the pit wall of the snow pit was also collapsing on a small scale. Although the impact was small, it was still dangerous.


    Fortunately, this kind of thing is very easy to deal with, as long as the prohibition of access to the snow pit.


    At present, the heating hub has entered a smooth operation, in addition to the need for continuous drainage, there is no need for additional maintenance.


    The whole heating hub is driven by electricity. Although there is a plan to use heat energy for power generation in the future, considering that there is no generator connected to the heating hub and there is no surplus heat energy for power generation at present, when Chen Xin designed the heating hub, he still used isotope thermoelectric battery for power supply.


    It has to be said that the isotope thermoelectric battery is quite easy to use. Chen Xin only needs to install the battery into the heating hub, and one battery is enough to keep the whole heating hub running smoothly for ten years.


    In this process, workers only need regular maintenance and overhaul of the heating hub, and then they can complete all the maintenance work.


    Because when Chen Xin designed the whole heating hub, he took stability and reliability as the main design standard, and the heating hub he built was also quite reliable.


    Of course, limited by materials, the whole heating hub still needs regular maintenance to avoid damage due to accidents.


    Because the snow around the heating hub is constantly melting, Chen Xin, together with the workers and the geological exploration team, has evacuated their original camp and rebuilt the camp in a new location.


    However, this camp is still a temporary camp. After the expansion of the heating field is completed and the snow within a radius of 200 meters is melted, Chen Xin will move to the heating field of the heating hub with his workers and geological exploration team.


    On the one hand, of course, it is to enjoy the warm welfare brought by the heating hub, on the other hand, it is also to be able to maintain the heating hub nearby.


    After all, it''s the first time that this thing has been put into use. No one knows whether it will break down or not.


    The construction of the new camp is not too troublesome. With Chen Xin''s power armor and mechanical arm, one person can stand up to everyone else in this kind of thing.


    They found a building that was not completely covered by snow, but also complete. They dug a row of snow pits against the wall of the building, put up tents under the snow again, and built a new camp.


    The new camp is far away from the railway station and the heating hub than the old camp. However, it is more stable when it is backed by the external wall of the building, and it can also play a windproof role for the buildings completely buried in snow.


    However, because this is only a temporary camp, as long as we can live in it, we didn''t manage it very carefully.


    However, Chen Xin spent a lot of time on the place where he used to install the electromagnetic metallurgical furnace. Every time the electromagnetic metallurgical furnace was running, it would release a lot of heat. Chen Xin had no choice but to choose a firm place to install it, so as to avoid the occurrence of accidents such as snow melting by heat and machine tilting.


    The reason why we attach so much importance to the electromagnetic furnace is that Chen Xin still needs to provide spare parts for the next several planned heating hubs, especially for the seventh middle school where Cao Daren is digging a well, but the backwater well has long been scheduled to build a second heating hub.


    Therefore, Chen Xin must seize the time to complete the relevant parts of the second heating hub, so as not to delay the construction period.


    This is one of the reasons why Chen Xin chose the building as the new camp site. Clearing a piece of space on the roof of the building is enough to install the electromagnetic furnace.


    After all, Chen Xin''s furnace itself is not heavy. As long as it is placed on the cement floor, it can stand steadily. Obviously, the cement floor is not as easy to melt as the snow floor, which is enough to ensure the smooth operation of the electromagnetic metallurgy furnace.


    Thanks to the scientific research department, Chen Xin did not need to go out to collect waste metals for the second heating hub. The materials transported together with the geological exploration team can fully meet Chen Xin''s needs.


    Compared with the waste metal collected by Chen Xin before, the performance of these materials is undoubtedly much better. According to Chen Xin''s requirements, different materials can be used for different parts according to the difference of material performance, which can improve the performance of the heating hub itself.


    For the simplest example, the heat sink of the first heat supply hub is made of waste copper recycled by Chen Xin. Although the heat dissipation performance of copper is better than that of iron, Chen Xin''s electromagnetic furnace can also purify and process the materials in the smelting process, the heat sink made of waste copper is obviously inferior to that made of new materials by Chen Xin in quality The board is broken.After all, one is only the product of secondary smelting after the recovery of copper scrap, while the other is the copper alloy specially made to improve the heat dissipation performance. Although the former can also meet the design requirements of the heating hub, it is obvious that the latter has higher heat dissipation efficiency and material properties.


    It is obvious that the scientific research departments that transport materials to Chen Xin get good things, and with these materials, even if Chen Xin does nothing but makes the materials into parts, it is enough to improve the work efficiency and output power of the heating hub by 10%.


    If we upgrade the system and optimize the design, even without actual data support, Chen Xin thinks that we can increase the work efficiency and output power by another 20%, and even increase the radius of the heating field of the heating hub to 250 meters or even 300 meters.


    According to another calculation model designed by Chen Xin before, when the heat sink of the heating hub is folded up and the heating field is not opened, the heat energy output of the heating hub is used for power generation, which is enough to reach 1MW ¡¤ h of power generation.


    As long as there are several such heating hubs to form a heating network, it is enough to meet the power demand of a city.


    Even in today''s environment, these heating hubs need to consume a considerable part of the heat energy for heating, and the remaining power generation is enough to meet the use needs.

 Chapter 375

    Chen Xin''s ability to upgrade is of great significance to a country, but it is not indispensable.


    Without Chen Xin, a country can develop, but with Chen Xin, the process of development is only accelerated.


    If you want to make an analogy, it''s like playing with stars and picking up a scientific research hub at the beginning, which can provide you with a large number of scientific research points each round, so that you can turn the technology that only produced one in more than ten rounds into several rounds or even one in a round.


    This can really give you a quick advantage and lead, but it won''t bring much improvement in the short term, because it takes time for technology to transform into strength.


    Whether it''s colonizing other planets or building fleets, it takes a lot of resources, energy and the most indispensable time.


    And these are not to say that simply upgrading science and technology can achieve a qualitative leap.


    What''s more, Chen Xin can''t play a more important role than a scientific research hub that can influence the overall situation. The scope of his ability to radiate is based on what he can touch.


    In short, if you don''t send what you are studying to him, he can''t play any role in the research.


    However, there is no doubt about the importance of Chen Xin to the current state of Yan. This can be seen from the whole newly refitted special forces carried on the train from three towns to Linshi.


    This is a special force with complete organizational structure, and its number is about the same as that of a reinforced company. The total number of troops is more than 150. All the troops are equipped with the latest military exoskeleton, heavy firepower of individual soldiers never seen before, and all kinds of newly distributed snow vehicles.


    Whether it''s firepower and mobility, or individual combat capability, this is an elite team that can make the enemy cold.


    In the past, it was not impossible for such an elite special force to play a far greater role than a regiment, or even a brigade or division on the battlefield as long as it was used reasonably.


    But now they have just been equipped with new equipment, and before they can adapt to the use of new equipment, they are dispatched to Linshi, and their main task is to protect Chen Xin.


    In terms of Chen Xin''s importance to the country, there is no problem in enjoying the protection of a special force. The role he can play can fully afford such treatment.


    It''s just that Chen Xin has always resisted this kind of thing. On the one hand, he felt uncomfortable that someone would follow him to protect himself. Just like Buddha didn''t want 500 Arhats to follow him wherever he went, Chen Xin didn''t want a bunch of people to follow him when he went out of the door.


    On the other hand, he doesn''t think he should waste the national resources like this. He is just a very ordinary person with no talent. He just gets the ability that ordinary people don''t have by relying on the system. He doesn''t think he is important enough to need someone to protect his steps.


    So at the beginning, after reaching an intention of cooperation with him, the state proposed to send someone to protect Chen Xin, but Chen Xin refused.


    At that time, the officials in charge of the talks with Chen Xin did not do so on the premise of respecting Chen Xin''s personal wishes and considering that Chen Xin had been living in his own shelter and there would be no great threat to his security.


    This time, however, after Chen Xin completed the construction and design of the isotope thermoelectric battery production line and exoskeleton protective clothing, which are of great significance to the country, his presence has reached the highest level of Yanguo, and his importance has been greatly improved.


    For the sake of protecting talents, the state transferred a special force with new equipment to protect Chen Xin.


    Of course, the military has played a considerable role in this. After all, it is enough to protect a person. Usually, a dozen people in a combat team are enough. Before the disaster, the federal commander just has a force on standby for him.


    Of course, there is no bad idea for the military to do so. What bad idea can brother Bing have? Just want to have more big bang.


    In fact, anyone who understands Chen Xin''s ability will have some ideas, and the new products he brings out aggravate such end-to-end Association.


    With exoskeletons, isn''t it good to upgrade to power armor?


    Isn''t it good to change the tank to electric propulsion?


    Although the humanoid robots like Kodak are not very practical, are the individual combat mecha and humanoid tanks not good?


    What''s more, isn''t it good to build a land cruiser like Rhode Island?


    In the past, of course, the military would not have such an idea. No matter how fragrant these things are, the top military officials knew that they could not be realized in a short time.


    There is still some hope for the realization of power armor or all electric tank, but there is also a lack of short-term practical possibility. As for other things, it can only be regarded as science fiction material.


    But Chen Xin''s appearance makes all this possible.


    Of course, the military is also a little careful, of course, it is not a bad idea.


    They just sent the special forces with the latest equipment to protect Chen Xin. At the same time, they told the officers and soldiers of the special forces that they would show these new equipment in front of Chen Xin when they had nothing to do, and then enticed Chen Xin to help them improve.As long as one or two pieces of equipment can be improved and mass production and promotion can be realized, this is a very cost-effective deal for the military.


    After all, the possibility of war breaking out in this situation is too low. Such an elite special force is also idle. It''s better to be transferred to carry out the protection task and get new toys by the way. It''s really very cost-effective.


    So the elite special forces were sent here, and their protection target Chen Xin did not know about it.


    This special force is carried by a special train specially approved by the military. In addition to the soldiers themselves and their personal equipment, there are also their vehicles, ammunition, supplies, mobile barracks that can accommodate all of them, high-efficiency communication facilities that can communicate with the superior headquarters, and other new equipment that may be used.


    Quite a lot of the supporting equipment is equipped for the first time. On the one hand, the military wants to test the effect of these new equipment. On the other hand, it also hopes to let Chen Xin see these new equipment. Maybe any new thing that interests Chen Xin can be improved easily?


    So these should have been put in the warehouse, and they would only be distributed when they needed to be used. The wrong new equipment was all packed and packed, and filled more than a dozen cars.


    Now this special military train, under the traction of the nuclear locomotive, has entered the city.


    However, at the first glance, what appeared in front of these special forces soldiers was a railway station that was constantly steaming, as if it had been boiled open.

 Chapter 376

    The impact of the arrival of a whole special force is amazing.


    Although this special force is only transferred to protect Chen Xin''s security, in the current situation, if a whole armed special force is transferred to the city, even if they do nothing, it is enough to make everyone pay attention to them all the time.


    This is a fully armed and well-equipped special force. In the past, people may have seen special forces in movies and TV, but it''s not so easy to see a whole special force, or a special force on the verge of war.


    This special force obviously didn''t care about other people''s eyes, and now in this weather, there are few people to watch.


    Those who can see this special force enter Linshi are just a group of porters temporarily organized by Linshi municipal government.


    They are responsible for helping these special forces unload goods from the military train, so they are lucky to see this special force, which can be called the most advanced equipment in Yanguo.


    It has to be said that when the elite special forces are equipped with exoskeletons with a sense of the near future, the combat effectiveness of the whole force may not be seen by ordinary people, but the atmosphere of extermination is enough to make people shudder.


    This group of porters organized by the city are basically ordinary people. Even in peacetime, it is inevitable to be a little nervous to see such a full armed force, not to mention that all people are depressed and nervous in this end of life environment.


    Affected by the momentum of these special forces, the city''s porters even feel a little nervous.


    Maybe some people think that the people''s soldiers should be warm and kind to the people, just like the soldiers and the people? How can it give people a sense of extermination and make these porters nervous to the point of trembling?


    The army we usually see is not so serious. When we see military vehicles and troops driving, we will not be afraid.


    But it was a time of peace. How could the soldiers who defended their country show their murderous side to the people they protected?


    Only when these soldiers are ready to fight, fully armed and ready to fight at any time, will these friendly people''s soldiers become like a sharp sword coming out of the scabbard and a fierce tiger coming out of the cage, enough to frighten any enemy who faces them and fear that the sharp sword will pierce their throat in the next second.


    Fortunately, the political commissar of this special force noticed this situation and made a mention with the team leader. They soon adjusted their position. These special forces put away their strength and cooperated with the porters more actively and cordially.


    This is a good way to ease the tension of these porters. After all, the army of Yan country is really like relatives to the people of Yan country. Just now, it was just scared.


    With the active cooperation of the special forces, the speed of unloading materials from the train was naturally improved, and soon all the materials were unloaded.


    The vehicles they brought were driven directly from the train, and they also temporarily served as a means of transportation to transport the unloaded materials away.


    This special force was ordered to protect Chen Xin. Naturally, the station they chose would not be too far away from Chen Xin.


    With the cooperation of the staff in the city, the special forces soon came to Chen Xin''s camp, which is not far from the railway station.


    The workers in the camp are relatively idle during this period of time. After all, the first heating hub has been built. They only need to be responsible for the maintenance and take away the melted water every day. They don''t need to work every day as they did in the previous few days.


    So when the special forces arrived, there were still a few workers in the camp resting.


    Standing on the roof, Chen Xinran, who is melting materials with an electromagnetic furnace to make parts for the second heating hub, noticed this special force for the first time. He was surprised by the great movement of this special force when it arrived, but he didn''t have any other emotions.


    After all, this is the state of Yan. Chen Xin doesn''t think this army will bring him any danger.


    Although there is no danger, it does not mean there is no trouble.


    "So what you mean by that is to let me move to your barracks and live under your protection 24 hours a day?" Looking at the commander and commissar of the special forces, Chen Xin scratched his head helplessly.


    He didn''t wash his hair for several days. His scalp is itchy.


    "Yes, Mr. Chen, the Military Commission has sent us to protect you for your safety. It''s safer for you to live in a military camp than in the wild." The political commissar of the special forces persuades Chen Xin that political cadres are really better at this kind of thing.


    Chen Xin shook his head: "the barracks are inconvenient. My work here requires me to focus on the construction site. Living in the barracks is not only troublesome, but also affects my work. What''s more, you are temporarily dispatched, and there are no ready-made barracks on the side of the city, right


    "You don''t have to worry about this, Mr. Chen. When we set out, the Military Commission specially allocated a batch of the latest mobile barracks. It only took eight hours to build a standard barracks, and we carried all kinds of heavy and light weapons to protect your safety." The political commissar emphasized safety, which was specially explained by the superior leaders before he came.For this army, their most important task is to ensure the safety of Chen Xin. Whether they can obtain new equipment from Chen Xin can only be regarded as a joint and several goal.


    But Chen Xin doesn''t want to live in a military camp. Although it''s really safe, it''s just too safe that people don''t like it. After all, he''s not a national leader. There''s no need for him to go out and pass several sentries. He''s surrounded by machine gun cannons 24 hours a day to protect his safety.


    However, Chen Xin is not a stubborn person. After thinking about it for a while, he said to the two officers in front of him: "I will not go to the barracks. There are too many restrictions for me, and many things will become inconvenient. However, I am willing to accept your protection. Just Send a few people to follow me. In this way, even if I want to go anywhere, it will be more convenient, and I won''t be able to go It''s too extravagant and wasteful, and it''s too influential. "


    Chen Xin''s proposal made the commander and political commissar of the special forces look at each other face to face. After they thought about it and discussed with each other, they finally nodded: "since Mr. Chen said so, we will be stationed near you, and then send a combat team to protect your safety."


    "That would be perfect." Seeing that they agreed, Chen Xin took a long breath.

 Chapter 377

    The special forces camp was soon built near Chen Xin''s camp.


    Today''s field barracks are no longer the kind of military green tent barracks that many people think.


    With the development of science and technology and the improvement of military logistics support capability, the barracks have long been different from before.


    It is not only becoming more and more modern, but also becoming more and more convenient and fast.


    With the help of exoskeleton, the barracks, which is composed of prefabricated houses and mobile shelter, is made up of explosion-proof walls and guard tower. It took only a few hours to build a barracks with complete functions and facilities.


    This kind of modular barracks is the army''s latest field camp construction technology. All materials have been processed before departure, and are numbered and classified according to the purpose, so that they can be installed in place in a short time after arriving at the destination.


    This is a new technology specially developed by the army in order to solve the problems of huge investment, long construction period, low frequency of use and poor support effect in setting up field camps in the past. This technology has only been applied experimentally in some military exercises before, but this time it is a real combat test in a sense.


    Because all the materials have been processed and classified, and they can be assembled very quickly. Although there is no construction machinery, with the help of exoskeleton, it takes a few hours for these special forces to complete the assembly of the prefabricated houses, put the mobile shelter in place, and even connect the water and electricity of the barracks, so that they can enter the barracks.


    Here I have to mention Chen Xin''s contribution to this matter. If it wasn''t for his completion of the construction of the first isotope thermoelectric battery production line, so that the country can mass produce isotope thermoelectric battery, which is a convenient energy source, these special forces can also quickly build barracks, but the water and electricity will not be so convenient.


    The traditional way of power supply is nothing more than fuel oil generator set and disposable power supply. Among them, the disposable power supply is the traditional battery. Although this kind of thing can be recharged repeatedly, its capacity is too small to supply limited small equipment. The power supply of the camp still depends on fuel oil generator set.


    But it has a very serious dependence on oil, and it is also a huge test for the logistics support ability of the army.


    After all, unlike the ancient army, the modern army doesn''t just bring food and grass. The modern army relies too heavily on the logistics support system. It can be said that logistics is the embodiment of the combat effectiveness of the modern army.


    If the enemy cuts off the logistics supply line and the troops are short of fuel, that''s not good news.


    Now, with the isotopic thermoelectric battery provided by Chen Xin, the army does not need to bring a generator. One installation of two batteries is enough to guarantee the power consumption of a temporary military camp.


    This is much better than using a generator. With the continuous progress of science and technology, the heat generated by the oil-fired generator set is very conspicuous in front of some investigative means. The heat emitted by two hot eggs can expose a latent army, let alone a generator set?


    What''s more, the isotope thermoelectric battery can be applied to vehicles. Compared with fuel vehicles, all electric vehicles rely much less on logistics.


    Let''s not mention anything else. Take the main battle tank as an example. Under normal circumstances, a tank can only carry enough fuel to run four or five hundred kilometers. This is still the data of road driving. If the terrain is complicated, a tank of fuel may be enough to charge.


    But the isotope thermoelectric battery is not the same. This kind of thing that can be used for ten years can be installed on the tank, not to mention four or five hundred kilometers. Even if you run four or five thousand kilometers, you won''t run out of oil. At most, the tank itself needs to be maintained.


    This alone is enough to change the way tanks are used as a weapon of war and make a new change in the war situation.


    This is also the reason why the CMC has sent a whole special force to protect Chen Xin. If it was before the disaster, he would have been invited to the military base under layer upon layer of protection, and foreign spies would have been staring at him like flies.


    The construction of the camp of the special forces was completed, and the combat team sent by the commander to protect Chen Xin also came to him.


    "Hello, comrade, we are the combat team ordered to protect you. You can call me Wang Hai. These are my team members. We will work with another combat team to protect your safety 24 hours a shift." A soldier with the rank of second lieutenant saluted Chen Xin and then introduced himself to him.


    "Oh, Hello, how are you going to protect me? Is there anything I can do for you? " Chen Xin took the initiative to say hello to the second lieutenant Wang Hai. They are here to protect him. He doesn''t need to show his face to others. Instead, he should actively cooperate: "my main job now is to make parts for the heating hub in the camp, and then go to the construction site according to the situation. In addition, you can only go out occasionally. You can arrange your action plan according to these Draw


    "Thank you for your cooperation, but there is no such exaggeration as you think, comrade. We will set up a guard around you, which will not affect your work at ordinary times. On the contrary, if you need to go out, we will send someone to follow you." Wang Hai was very happy with Chen Xin''s cooperation and explained his arrangement to him.For the special forces like Wang Hai who carry out the protection task, the cooperation of the protected targets can undoubtedly reduce a lot of their work, so that they can better carry out the protection task.


    In addition to his own character, Chen Xin''s cooperation also comes from Qin Lan''s influence on him to a great extent.


    After all, Qin LAN used to be a special police officer, and has also carried out protection tasks. Chen Xin also heard about the possible problems and effects when he first contacted Qin LAN, so he also knew how to cooperate to protect his own people.


    After introducing his team members to Chen Xin, Wang Hai asked them to spread out and set up a guard near Chen Xin''s camp, while he and another soldier followed Chen Xin.


    Chen Xin didn''t feel uncomfortable when he had two more people around him. Although he was not used to it, it didn''t hinder him, so he let it go.


    However, looking at Wang Hai''s military exoskeleton protective clothing, he became interested. After all, it was produced according to his original drawings. Chen Xin wanted to see how different the national production was from his own.


    "Can I have a look at your exoskeleton?" Chen Xin asked Wang Hai.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 378

    Chen Xin wants to have a look at his exoskeleton. Wang Hai certainly has no idea or reason to oppose it.


    Before he came, both the team leader and the political commissar told him that in addition to protecting Chen Xin''s safety, the most important thing was to ask him to help improve his equipment.


    Wang Hai was still trying to achieve this in what way. Now Chen Xin takes the initiative to take a look at his exoskeleton. It''s just dozing. When he meets a pillow and sends it to the door, Wang Hai naturally agrees immediately and takes off his exoskeleton and puts it in front of Chen Xin.


    See Wang Hai so on the road, Chen Xin just need a little bit over the brain can understand what is going on.


    However, he doesn''t care about it. After all, it''s a good deal for him to improve his armaments. When will it be useful to sell favor to the military?


    Just like now, if the military does not want to upgrade its military equipment, how can it deploy a fully armed special force to protect him?


    A few thoughts flashed through his mind. Chen Xin didn''t think too much about it. Instead, he focused on the military exoskeleton in front of him.


    Military exoskeletons are essentially different from civilian exoskeletons that Chen Xin had seen before.


    Although all exoskeletons are exoskeletons, the main material of civil exoskeletons is metal. Besides being bulky, the strength of the body is relatively small. At the same time, the exoskeletons have no protection for users. In short, they are just a power assisted mechanism. There are no additional equipment on them. They are just some basic accessories.


    But the military exoskeleton is different, its main structure not only uses high-performance alloy with better performance, but also uses a large number of engineering plastics as materials, so that the whole exoskeleton is not only lighter, but also more able to adapt to the harsh environment.


    Engineering plastics are not ordinary plastics. This kind of material can be used to make mechanical parts or engineering materials instead of metal materials. Compared with ordinary metal materials, it has high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation. It can be used in harsh chemical or physical environment.


    For the current low temperature environment, the use of engineering plastics is much better than metal materials, but the cost of engineering plastics is much more expensive than metal materials.


    Therefore, the elite troops can use this kind of sparing no cost equipment. The ordinary troops may not have such an advanced version.


    Accordingly, since the country has spent a lot of energy to build, these exoskeletons are naturally more functional and powerful.


    It not only has the upgraded and enhanced version of the oxygen supply, lighting, communication and other functional modules on the exoskeleton of the ordinary civilian version, but also has the weapon rack, ammunition storage box, emergency medical kit and other accessories that will not be equipped on the civilian version, which can be said to be enough to meet the needs of a soldier in various environments.


    In addition, there are some experts in the national design and research of exoskeletons. Although there are some hard conditions that can not be achieved due to the constraints of the level of science and technology, the practical exoskeletons can not be made before, but after Chen Xin made the original version of exoskeletons, there is no problem in improving them.


    So this set of military exoskeleton is much better than the original version that Chen Xin made with the help of the system. The two can be summarized as the difference between the prototype and the special installation machine.


    Wang Hai''s exoskeleton is a surprise configuration, with balanced performance in all aspects. The added bulletproof plug-in board provides enough protection. The blessing of exoskeleton itself adds a lot of agility. With the improvement of strength, it can carry more auxiliary equipment and ammunition, which is enough to turn the soldiers wearing this exoskeleton into war machines on the battlefield.


    In particular, this exoskeleton obviously has some interface hanging points that can be modified and added with other accessories. It can carry heavy weapons that can only be equipped by vehicles, such as heavy machine guns, rockets and so on, so that ordinary soldiers can not only play a strong firepower, but also have the flexibility that individual soldiers should have and play a stronger combat effectiveness.


    Facing this set of exoskeleton, Chen Xin couldn''t think of how to improve it.


    After all, Chen Xin is not a weapon expert, nor is he a genius cursed by knowledge who can make a set of power armor out of thin air. He mainly relies on his extensive knowledge and experience as a network writer.


    The insight brought by his extensive study enables him to say something about many things, but it does not mean that he is omniscient.


    In fact, Chen Xin has encountered this situation several times. In the project samples sent by the state for him to improve, there are some things beyond his knowledge. When facing these things, Chen Xin will feel that the mouse can''t pull the turtle.


    Fortunately, this is just the difficulty brought about by Chen Xin''s limited knowledge. In front of the system, as long as there is a survival, upgrading is just an idea.


    Even if Chen Xin doesn''t know how to upgrade and doesn''t have a concept, he can also improve the performance of the item by force.


    Although the system upgrade is largely based on Chen Xin''s ideas and subconsciousness, if he does not have ideas, he will not be able to upgrade, but it does not say that if Chen Xin only has the idea of upgrading, the items can not be upgraded.So in this situation where he can''t figure out how to improve himself, Chen Xin''s usual practice is to directly smash the survival point and forcibly upgrade.


    However, this exoskeleton doesn''t need to be done. Chen Xin studied it for a while, turned to Wang Hai and asked, "this exoskeleton is very well designed. Do you think it needs to be improved in daily use?"


    Chen Xin, this is also a proper question. After all, it often takes a long time for a set of equipment from research and development to finalization. It''s not that designers can determine the final performance of the equipment by patting their heads in the office. It''s inevitable that a batch of samples will be produced and sent to the army for actual use, and then feedback will be collected to finally adjust the appropriate products.


    Wang Hai naturally understood Chen Xin''s meaning, but he couldn''t say: "we only developed this set of equipment before this mission. We just mastered the usage of exoskeleton, and now we can''t say where we need to improve it."


    Hearing Wang Hai say so, Chen Xin also clearly nodded and gave the exoskeleton back to him: "in that case, you can use it first. If you have any problems in actual use, please come to me. I''ll see how to improve it for you."


    "All right!" Wang Hai quickly agreed. Although Chen Xin didn''t help upgrade his exoskeleton this time, since he agreed, the subsequent improvement of the exoskeleton would be settled. The task assigned by the superior was not successfully completed, but at least the goal was achieved.

 Chapter 379

    The arrival of the special forces is good news for Chen Xinyi and other workers.


    At least, they can go to the canteen of the barracks every day instead of cooking in the snow pit.


    And the place to eat can also go to the canteen of the military camp, and sit comfortably on the table. You don''t have to rush back to the tent to hold the lunch box every time the meal is ready, for fear that if you stay outside for a while, the meal will be cold.


    What''s more, this is a field camp of special forces. The food standard is much better than the previous food standard of workers. When these workers come here to rub their meals, the army can''t do a separate job for them.


    What''s more, a few workers, Chen Xin and members of the geological exploration team cooked their rations together with those of the army. It''s not a big deal to eat them together. It''s just to check the food more to avoid some unnecessary accidents.


    Originally, the commander of this special force wanted Chen Xin to take the workers and the geological exploration team to live in the military camp, but Chen Xin declined this proposal, and the workers and the geological exploration team could only continue to live in their own camp with Chen Xin.


    There seems to be no desire to move to the military camp.


    Although the conditions of the barracks are better, they can live in prefabricated houses and sleep in decent beds. The conditions are much better than the tents in the snow pit, but the barracks are bound for ordinary people. Even if the conditions are good, ordinary people will still have a certain fear.


    What''s more, considering the accommodation conditions of these workers, the commander of the special forces also spared a set of spare mobile barracks they brought, which were built in the snow pit to improve the accommodation conditions for them.


    This mobile barracks is mainly composed of movable board houses. The specially processed heat insulation plates and steel prefabricated parts are combined together to form two complete barracks with modular bathrooms and toilets, and an additional office, which instantly makes Chen Xin''s living conditions rise to a higher level.


    Because of this, the workers and the geological exploration team will not have any opinions on Chen Xin''s refusal to live in the military camp.


    Of course, this mobile barracks is not as simple as a few prefabricated houses. In fact, such a mobile barracks also comes with supporting water and electricity facilities and air conditioning, which is enough to enable soldiers using mobile barracks to obtain better logistics support in any environment.


    Of course, now the cold air conditioning of the mobile barracks is not available, and the plywood of the barracks wall is also treated with cold protection. When the air conditioning is turned on, in the face of the low temperature of dozens of degrees below zero, the mobile barracks can still ensure that its internal temperature is comfortable enough.


    For this mobile barracks, Chen Xin has some ideas than the exoskeleton facing Wang Hai, because if this mobile barracks continues to upgrade, it will either develop into a large LEGO or an orbital airdrop module, just like the population building of the Terran in StarCraft.


    Even if we don''t use sci-fi technology, through certain design and transformation, we can turn the original building block type prefabricated house into a folding house. After it is transported to the place, we only need to select the location, and then it can be directly launched, and it doesn''t take time to assemble, which is also excellent.


    Chen Xin mentioned this idea to the political commissar of the special forces, and happily agreed to the convenience, saying that Chen Xin could transform the mobile Barracks at will, and it would be fine if it was damaged.


    For the military, although Chen Xin was not the first to improve combat equipment such as guns, logistics equipment is sometimes more important than guns.


    It''s like the modular planting shelter in the military camp. They can provide fresh fruits and vegetables for the army anytime and anywhere, which is an important guarantee for the combat effectiveness of the army.


    However, although he planned to start the transformation, Chen Xin did not immediately upgrade the mobile barracks.


    At present, the most important thing for him is the construction of the heating hub. Although upgrading equipment for the military is also a very important thing, Chen Xin''s priority is still not as high as that of the heating hub.


    After all, the latter has little influence earlier and later, but the former matters a lot.


    During the time when the special forces arrived, Cao Daren finally drilled the backwater well in the seventh middle school.


    Knowing the news, Chen Xin immediately took the spare parts of the second heating hub that had been prepared and went to the seventh middle school with the workers.


    There is another advantage of the close protection of the special forces, that is, Chen Xin can now go out for nothing to whore the special forces vehicle.


    Although this special force has only one company with more than 100 troops, it carries many vehicles. In addition to five JM8 all terrain vehicles with different functions, there are nine Bobcat all terrain vehicles and two Python all terrain vehicles.


    Among them, the python type is a heavy-duty vehicle with a load of more than 30 tons, which is mainly used to transport materials and ammunition. The steeds are lighter than the python type. The load is not so high, but they are more flexible. In addition, the hinged design can replace different hanging cabins to play various roles. The five steeds carried by this team have different functions.Chen Xin asked them to borrow one of the steeds to carry the transport bucket for hauling the parts of the second heat supply hub. After all, it''s not far from the camp to the seventh middle school, but it''s not near. It takes a lot of time and effort just to rely on the workers to carry the parts.


    But with a tow truck, it''s totally different.


    In less than half an hour, the team of one steed and three Bobcats transported Chen Xinhe, his workers and the spare parts of the second heating hub to the seventh middle school. Wang Hai also came with his combat team.


    "Here you are, writer! What''s the matter with these soldiers? " When Cao Daren saw the motorcade coming, he was obviously surprised. He didn''t expect to see the people in the army.


    "Nothing. They''re here to protect me. You don''t care." Chen Xinchong and Cao Daren simply explained, and then asked him about the situation here: "has the backwater well been drilled here? Is there anything wrong? "


    "Don''t you mind if I do things? The well has been drilled, there is no problem, just waiting for you to install the heating hub. " Cao Daren watched the workers unload the parts of the heating hub from the car, looking relaxed.


    "All right, check it for the last time, and start to install the equipment if there is no problem." Chen Xin saw that Cao Daren was confident and didn''t say much.

 Chapter 380

    Because of the construction experience of the first heating hub, when building the second heating hub, both Chen Xin and Cao Daren learned the relevant experience, improved the construction process, and made the construction of the second heating hub more smooth.


    For example, when they built the first heating hub, Chen Xin dug up the snow and laid a good foundation underground before they began to assemble the heating hub. However, when they built the second heating hub, they did not do so.


    Instead, we use the method of digging down and assembling the heating hub at the same time. After the pit is dug, the equipment is also assembled, and it only needs to be fixed to the foundation.


    This construction method undoubtedly saves a lot of time. Although the installation period of a heating hub is not long, it is good to save some time.


    The workers are working nervously. Wang Hai and his combat team spread out around to set up a guard. Chen Xinze and Cao Daren are discussing the next construction plan.


    The two heating hubs have been built now, but under the two heating hubs, there is a pumping well and a return well. If they want to play their respective roles, they also need to lay pipelines between the two towers to re inject the water from the pumping well into the ground through the return well.


    However, the laying of this pipeline is a troublesome thing.


    First of all, the bottom of the heating hub is at the original ground level, that is to say, it is more than 10 meters lower than the current snow level.


    The pipeline needs to be laid close to the ground, not on the snow. After all, when the heating hub works, it will melt the surrounding snow. The snow itself may be affected by wind, temperature and other natural factors, and it is not stable enough.


    This means that the pipeline between the two heating hubs must be drilled under more than ten meters of snow before construction.


    As for digging up the snow, Chen Xin vetoed the plan without even thinking about it. It''s not worthwhile to say that the amount of construction is too large.


    The distance between the seventh middle school and the railway station is not far, and the terrain is relatively flat. If you want to lay a pipeline, it is very simple without snow.


    But once plus more than ten meters thick snow as the premise, simple construction will become very troublesome and difficult.


    "It''s feasible to let workers dig holes, but the efficiency is too low, and the speed is too slow. Although it doesn''t seem far away, it can''t be finished in ten days and a half months! It''s a waste of time. " Cao Daren took the map and measured the distance between the seventh middle school and the railway station. He frowned and said to Chen Xin.


    Chen Xin also nodded. For such a long distance, even before the disaster, it would take several days to lay a pipeline. Now it is still necessary to dig a hole under the snow more than 10 meters deep. Even if the snow is easier to dig than the soil, it is not an easy job, and the efficiency is low.


    "But no matter what, the pipe must be paved! Even if we really let the workers dig by hand in the end, we still have to dig. " Chen Xin first set the tone for this matter, and then said to Cao Daren, "is there any other simple construction method? Like melting snow, or saving time with tools? "


    "Unless it''s the shield machine, but where can we get the expensive shield machine in a small place like Linshi? Things that don''t exist in the urban area can only be obtained by the provincial capital, and now even if you can, you still don''t know if you can deliver them. " Cao Daren knows about shield machine, but he doesn''t think it''s realistic. This kind of large-scale equipment specially used for underground drilling is not so ideal.


    "Shield machine? If you really want one, it''s not impossible... " Chen Xin knows that he can get it if he needs to, but this is not Chen Xin''s first choice.


    It''s not that Chen Xin is hypocritical or anything, but that he thinks it''s just to lay a pipe under the snow, and there''s no need to use the shield machine.


    They don''t want to build a subway. What they are facing is not hard rock. It''s just snow. If it''s not that the snow is more than ten meters thick, and he also wants to shorten the construction period, so that workers can dig it by hand.


    We should know that the cost of a shield machine is tens of millions, and it can lay pipes while driving, which is a real overkill to deal with snow.


    Cao Daren didn''t know what Chen Xin was thinking. He was surprised to hear that he could not get a shield machine: "writer, you don''t really want to get a shield machine, do you? That''s too wasteful. If you have the time to use shield machines, it''s better to find more workers to work separately to increase efficiency! "


    "It''s also a way, but is there no better way?" Segmented construction can improve efficiency. Of course, Chen Xin can think of it, which is also a practical solution, but Chen Xin still thinks that there should be some simple methods.


    However, he was not a sharp minded man. He didn''t come up with a suitable method, but he didn''t demand it. So he said to Cao Daren, "now that he can''t think of any good method, he can only use the method of sectional construction. I''ll go back and contact the staff in Lincheng to see if we can send some more workers to us. "


    "OK, as long as there are enough people, I can guarantee to finish the task on time according to the quality and quantity!" Cao Daren agreed, and made a promise to Chen Xin.In fact, this kind of thing is simple and easy. As long as there are enough manpower to carry out the construction in sections, it is not difficult to save time.


    But Cao Daren looked at the special forces on guard around him and asked Chen Xin, "writer, can these soldiers come and help? I think they all have exoskeletons, and they are certainly more efficient than ordinary workers. With their help, we can build much faster! "


    "These are all special forces. They are different from ordinary soldiers. Besides, they are here to protect me. It''s hard for me to ask them to help with the construction." Chen Xin shook his head and rejected Cao Daren''s idea.


    "In this way, we can only rely on ordinary workers. I really envy them for having exoskeletons. It''s an artifact to work with." Cao Daren''s words are full of regret. Looking at the exoskeleton of the special forces nearby, he is full of envy.


    Seeing this, Chen Xin couldn''t help laughing and said to him, "if you really envy me, I''ll come back and find a way. I can''t get the shield machine, and several sets of exoskeletons are still OK."


    Cao Daren heard Chen Xin say so, his face also showed a surprise expression: "that feeling is good! If we can have exoskeletons, we can at least double the efficiency of workers! "

 Chapter 381

    The construction of the second heating hub is very smooth, but even if the construction is completed, the heating hub can not be put into use immediately like the first heating hub.


    Limited by the fact that the return well below is used to inject water into the ground, this heating hub can not directly extract heat from the ground, but can only rely on the hot water extracted from the first heating hub on the other side of the railway station, which is transported by the pipeline, to play the role of the heating hub.


    As for whether the hot water extracted from the first heating hub can still be supplied to the second heating hub after its own evaporation and heat dissipation and pipeline transportation, it depends on the total amount of heat energy carried by the groundwater extracted from the first heating hub.


    "As long as the hot water extracted from the first heating hub can provide enough heat, there is no problem in supplying the two heating hubs." In the face of Wang Hai''s question, while planning the pipeline construction line, Chen Xin explained to him: "in addition, each heating hub is installed with an isotope temperature difference battery, and the output power of the battery is maintaining the operation of the heating hub. As for the surplus, the electric heating mode can be turned on when necessary."


    After listening to Chen Xin''s explanation, Wang Hai seems to know nothing about it. He is just a soldier. He doesn''t know much about this kind of thing, and he just asks.


    Chen Xin naturally knows that Wang Hai doesn''t know much about this kind of thing, but he just gives a smooth explanation and adjusts his mood after work.


    Otherwise, it would be very tiring to work so sullen all the time.


    "In that case, the heating hubs built in the future are all in this mode of pairing?" Wang Hai looked at the standard points on the map in front of Chen Xin and made a little analysis to determine that these points should be the places where the heating hub will be built in the future.


    "Not necessarily, I may take a more effective way in the future." Chen Xin shook his head, opened the projection on the power armor and projected the drawings of the heating hub and energy tower.


    This time, however, Chen''s projection is not a plan, but a three-dimensional image.


    "This is the energy tower that I plan to build to extract deep geothermal energy. It will extract geothermal resources from a depth of more than 3000 meters underground, transport a large amount of heat energy to the surface, then transport it to various heating hubs through pipelines, and then re inject it into the ground through the pipelines below the heating hubs." Chen Xin explained and controlled the projection for demonstration, which made Wang Hai intuitively understand what kind of system this is and how it works: "this is the heating network I designed. Now these two heating hubs are just a test unit, to verify whether my idea is feasible. After the relevant problems of this technology have been verified, it will be a real challenge The construction of a new heating network will begin. "


    Wang Hai looked at the projection demonstration in front of him, but he couldn''t help raising his eyebrows. Although he didn''t understand it very well, he probably knew the benefits of such a heating network, which made him feel quite confused.


    But Chen Xin told Wang Hai about these things, of course, not just to show him.


    Limited by the troubles and troubles caused by the pipeline construction, Chen Xin told Wang Hai that he just wanted to clarify his ideas while explaining these things to Wang Hai, so that he could use his brain to think about whether there was a way to complete the pipeline laying work in a short time without using a lot of hands.


    Of course, part of the reason is that Chen Xin himself has a strong desire to express himself. He is a performance personality. He likes to show others his ideas and ideas in this way, which will make him feel very successful.


    It''s like saying that a performer always needs the audience to appreciate his performance on stage. As a novelist, even if he is only a network novelist, Chen Xin hopes to have more people to read and appreciate his works.


    Even now that he has stopped writing books, he hopes that the things he creates will be praised by others.


    However, apart from showing off, Chen Xin is really thinking about how to solve the problem of pipeline laying.


    Now it''s only a few thousand meters away. It''s a way to solve the problem by putting in a lot of manpower, but it''s also a stupid way.


    If possible, Chen Xin hopes to have more efficient and smarter ways to solve problems.


    After all, if you want to build a heating network in a real sense, the laying of pipelines will inevitably become one of the problems in the construction process.


    Instead of leaving the trouble to be solved later, it''s better to think about how to solve this problem once and for all.


    Of course, the best solution to this problem is to use the shield machine. Although the cost of using the shield machine is high and the snow is not suitable, the shield machine is indeed the best solution to this problem.


    As for the problems existing in the shield machine, this is a good solution for Chen Xin, and it is good to use the system for targeted upgrading.


    As long as there is a system, Chen Xin is confident to transform a shared shield machine.


    Chen Xinzheng thought this way, but he suddenly realized that since he was able to upgrade the existing shield machine, why not design a shield machine that can be used here?The real shield machine is used to build tunnels. It''s huge. Because it has to face the complex terrain conditions such as rock stratum, it also has extraordinary requirements for material, so the natural cost is very expensive.


    But what Chen Xin wants to use here is different. First of all, what Chen Xin needs to face is not hard rock and complex soil layer, but homogeneous and soft snow. In terms of material, even if Chen Xin uses wood to make a shield machine, he can dig snow.


    Moreover, Chen Xin doesn''t need to dig the hole much. He just needs to be able to lay the pipe in. Even considering the construction of laying the pipe, he just needs to make a diameter as big as two people can work inside.


    Even Chen Xin doesn''t need to dig out how strong the tunnel is, as long as it can be supported until the pipeline construction is completed, even if it collapses later, it doesn''t matter to Chen Xin.


    And digging such a tunnel, naturally, the requirements for mining tools are not so high.


    In short, Chen Xin does not need to build a real shield machine. All he needs is a tunneling tool, which is not difficult to build.

 Chapter 382

    In fact, it''s not as difficult to make a shield machine as many people think, because the world''s first shield machine was born at the end of the 18th century two hundred years ago, and it was also hand dug. Compared with today''s large mechanized shield machine, there is no high-tech part.


    However, although the early shield machine has simple structure and no high-tech place, it is the originator and principle source of modern shield machine.


    Chen Xin wants to build his own shield machine. Unless he finds another way to design it from scratch, he can''t get around the principle of shield machine, which has laid the foundation more than 200 years ago.


    The principle of shield machine is not complicated. The main principle is to build a shield to protect the tunnel and resist the collapse of the tunnel while the TBM is driving forward, that is, to repair while digging.


    Of course, with the progress of science and technology, although the principle of shield machine is still the same, some large or super large shield machines no longer need to build "shield" in the process of excavation, they can directly repair the tunnel in the process of excavation, which is convenient and fast.


    The basic principle of the shield machine comes from a marine organism, the ship maggot, which continuously digs into the wood and secretes mucus to protect the wood around its body from corrosion and expansion by sea water.


    So for Chen Xin, he doesn''t need a regular shield machine. In fact, he only needs to make a machine that can dig quickly in the snow, and support the excavated tunnel so that it doesn''t collapse before the pipeline construction is completed.


    And it''s not hard to do either.


    Snow is not frozen ice. Although it has a certain hardness, it is easier to excavate than soil. Moreover, the texture of snow is uniform, and there is no complex structure. There is no need to consider the problems of rock strata or other complex geological structures encountered in the process of excavation.


    As for the second point, it''s easier to solve. At the current ambient temperature, just heat the excavated tunnel wall slightly during the excavation process, so that the snow on the tunnel wall melts and condenses quickly, and an ice shell can be constructed to support and protect the tunnel from collapse.


    After all, it''s just snow, not any complicated geological structure. It''s enough to have an ice shell to support it.


    And clear these two points, want to be able to use a shield machine, primary school students may not be able to, but the hands-on ability of some high school students can complete the design.


    A cylinder is used as the main structure, in front of which a blade or drill bit like a fan blade is made of relatively hard metal, and a circle of electric heating wire is laid on the shell for melting snow and internal insulation. This thing is basically completed, and can meet the needs of construction.


    As for the rest, it''s nothing more than to optimize the internal mechanical structure and add some auxiliary functions.


    For example, the fan blade or drill bit in front can be shaken by human power, or it can be made into mechanical power by adding a motor. The snow dug can be transported by human power, and it can also be mechanically transmitted. Even Chen Xin is willing to spend some time to make the whole shield machine fully automatic. He only needs to put it into the snow to dig and complete the whole construction by himself.


    But Chen Xin was a little hesitant about how big a device he wanted to build.


    It''s a simple and crude way to build a large tunnel, dig a tunnel directly, and then the workers go in and set up the pipeline. In this way, the machine doesn''t need to be too complicated and advanced, so it can dig quickly.


    But in this case, the construction speed will be relatively slow. After all, if the construction is large, the heading face will be relatively large, the amount of snow work to be excavated will be doubled, and the construction period will be longer.


    As for building a small one, or simply only having the thickness of the pipeline, it will undoubtedly save a lot of work to dig and connect the pipeline.


    But relatively, if we build small shield machines, the technical content will undoubtedly have to be improved a lot.


    After some consideration, Chen Xin weighed the advantages and disadvantages between the two and chose the small shield machine.


    After all, it''s the easiest thing for him to improve his technology.


    With a multi-functional mechanical arm, it is not difficult to process such a shield machine. It only needs to cut a section of pipe, install a drill bit for tunneling at one end of the pipe, connect a pipe inside to remove the "ice shaving" from the excavation, and finally connect the motor to provide power and power. This thing is even good.


    Of course, although this thing is ready and can be used to start work, Chen Xin still needs to give him a small promotion if he really wants to put it into use and rely on it for tunneling.


    For example, it is necessary to install a microcomputer on it, so that the equipment can be remotely controlled or programmed to operate automatically.


    Chen Xin even considered installing a 3D printer on this little thing, which can print the pipeline directly while driving, and even omit the layout of the pipeline itself.


    However, after some consideration, Chen Xin still didn''t do so. He just installed a remote control on the small shield machine he made to ensure that he could control the machine forward, backward and stop by remote control.


    The final shield machine is like a bullet. The front end of the machine is a hollow drill. It cuts ice and snow through the arc-shaped edge, and then the broken snow is removed through a pipe inside the drill to ensure the smooth progress of the drill.In addition to the pipe, there is a heating ring behind the drill, which is used to heat the snow around the whole shield machine. After the snow melts, it quickly freezes under the influence of low temperature to form an ice shell to stabilize the tunnel.


    The power of the whole shield machine comes from a small power motor installed in it by Chen Xin, which is responsible for driving the drill bit and the crawler wheel at the bottom of the shield machine forward, while the power supply relies on a small battery.


    After Chen Xin finished the shield machine, he took it to the nearby snow for an attempt, and the experimental results are very ideal.


    The drill bit worked very fast in the snow. Chen Xin only allowed it to drill for about three or five minutes, and then drove forward for about two meters. According to this speed, one hour is enough to drive 20-40 meters, which is much faster than relying on manpower.


    Seeing that the shield machine he made was quite effective, Chen Xin was satisfied and was ready to let the workers prepare for the construction.


    But at this time, some workers asked Chen Xin the question, shield machine really can dig quickly, but how to put the pipe into the tunnel?


    The diameter of the shield machine is only a few centimeters thicker than the pipe. It''s no problem to put the pipe straight in along the drilled tunnel, but the pipe is not a straight branch, but there is an elbow in the middle.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 383

    Because the pipeline construction needs to avoid the buildings on the ground, and considering the influence of factors such as thermal expansion and cold contraction, the pipeline cannot be pulled into a straight line, and the elbow must be set in the middle.


    So in the process of construction, how to install the elbow, and how to deal with the change of pipeline direction after the installation of elbow, has become the problem Chen Xin must consider.


    The installation of the elbow itself is easy to say. It''s a big deal to dig a shaft from the ground to put it down. Although there is a certain amount of work, it''s still easy to complete. As for how to weld, Chen Xinda can use the mechanical arm of the power armor to do it.


    But after the pipeline line changes direction, how to put the pipeline down is a difficult problem for Chen Xin.


    In the past, if you want to lay a pipeline, if it is not directly on the ground, the most common way for the construction party is to excavate the whole ground for construction, and then cover the soil and backfill after completion.


    Of course, Chen Xin can also use this method. He can dig up more than ten meters of snow to put down the pipeline. Unless Chen has hundreds of exoskeleton equipped workers and a lot of construction machinery, he is not suitable for such a huge construction method.


    And if Chen Xin wants to use this method to construct, he doesn''t have to make a small shield machine himself.


    Facing this problem, Chen Xin did not scratch his head alone, but found Cao Daren and asked him if there was a suitable way.


    After all, Chen Xin used to be only a writer who wrote online novels. Although he didn''t completely understand this kind of construction project, he certainly didn''t have much contact with Cao Daren.


    "If this is the problem, I suggest you use the pipe jacking method for construction." Sure enough, when Chen Xin asked, Cao Daren had already given a practical plan, and said to Chen Xin, "I thought you had already thought of using this way to construct! The shield machine is used for tunneling, and the pipe is jacked in one by one at the back. Isn''t this the plan you expected in advance? "


    "The plan I envision is really to use the shield machine to dig the tunnel, and then put the pipe in, but it''s still a little different from the pipe jacking method you said." Listening to Cao Daren''s introduction, Chen Xin understood how the pipe jacking method was going on, but it was quite different from his original construction method.


    With the development of science and technology, pipe jacking method is a kind of pipeline construction method to solve the problems of complex underground pipeline and inconvenient excavation.


    The main way of construction is to excavate the operation well to reach the operation depth, and then use Jack and other tools to push the prefabricated pipeline one by one into the predetermined pipeline at the predetermined pipeline position to realize the pipeline installation.


    Of course, this technology is mainly used in the installation of large pipelines, and according to the different ways of pipe jacking, it can be divided into mechanical excavation jacking, extrusion jacking, hydraulic mechanical excavation jacking and manual excavation jacking.


    Chen Xin''s shield tunneling method can also be regarded as mechanical excavation jacking.


    "In this case, we need to take thermal insulation measures for the pipeline first, and then put it into the operation well for jacking operation." For the scheme given by Cao Daren, Chen Xin agreed after thinking about it, and soon thought of the problems that should be paid attention to in the construction.


    When Cao Da heard Chen Xin say this, he nodded and said, "this is for sure. It''s impossible to do insulation after the pipes are laid. That would be too troublesome."


    Cao Daren agreed to carry out jacking operation after the pipeline was insulated, mainly because the working surface where they installed the pipeline was snow, not soil or rock, because if it was soil or rock, which was harder, the insulation material wrapped in the outer layer of the pipeline was easily worn during jacking.


    "Can you do this? I''m not a professional engineer after all, and I have other things to do. " Chen Xin looks at Cao Daren and asks him.


    What he said was the truth. Although he had been in touch with engineering construction when he was still at work, Chen Xin at that time was not the person in charge of directing the construction on site and had no experience in this field.


    As for the other things he said, it''s his cooperation with the country. The prototypes of the projects that need him to upgrade and improve have been transported to Linshi by military train with special forces before, and are now stored in the military camp.


    And the prototypes of related projects previously accumulated in the urban areas are also preparing to be transported recently, so Chen Xin really needs to deal with these things during this period of time, so as not to delay the progress of national projects.


    Although Chen Xin''s appearance is only a surprise for the country, and the original project plan was designed without his help, it doesn''t mean that Chen Xin can leave the work that should have been completed behind.


    So Chen Xin plans to take advantage of the construction of the second heating hub and pipeline laying to clear up the backlog of work first.


    Moreover, for Chen Xin, he has been busy with all kinds of things during the time when he came to Linshi for disaster relief, first the ambulance station, then the railway station and the heating hub. After this busy journey, he took a little rest on the new year''s day, and was finally given a big "surprise" by Qin LAN and Mo Qingyan.This also makes Chen Xin want to take advantage of the opportunity that other things are on the right track during this period to change his mind by dealing with the backlog.


    Chen Xin took the initiative to deal with the backlog of work, which is of course what the researchers around him can''t wait for.


    The researcher has been here since he came to Linshi. In addition to being responsible for contacting the urban area and the superior departments, the researcher has also helped Chen Xin a lot. At least he has contributed a lot to the construction of the heating hub.


    In the past, he needed to use the communication channel of Linshi municipal government to contact with the superior departments. Now the special forces have come, which not only built the barracks, but also brought the communication facilities and set up the communication network, so that the researcher can use the communication equipment of the special forces to get in touch with the superior departments more conveniently.


    This is a good thing for both the researcher and Chen Xin, which makes their communication with the superior departments much smoother. After all, it is somewhat inconvenient to borrow the communication channel of Linshi municipal government before.


    The special forces don''t have such troubles, because they are equipped with perfect communication equipment when they come, which also has the factor of ensuring Chen Xin''s communication with the superior scientific research department.

 Chapter 384

    In the barracks, Chen Xinzheng fiddles with a disassembled equipment in front of a workbench.


    Although his upgrading of the project prototype sent by the state all depends on the upgrading ability of the system, it does not mean that he really knows nothing about the improvement of the equipment.


    At least with the help of a mechanical arm, take apart a project prototype to see what structure is inside. Chen Xin can still make it.


    This is one of Chen Xin''s hobbies since he was a child. He always wanted to take apart things to have a look. More than half of his toys were broken like this when he was a child.


    Because at that time, the ability was limited, so it would not be able to install it after being disassembled. Or, like the plane repairmen in the third family next door, they could save a new plane after repairing a few more screw parts.


    Of course, now that Chen Xin can''t take it apart, he can''t take it back. Not to mention the improvement of his ability, he is sure to take it apart and put it back. With the help of the mechanical arm and the microcomputer, he can''t take it apart and put another screw on the table.


    The device in front of Chen Xin is one of the plug-in devices of military exoskeleton, which is a laser guidance module.


    The so-called laser guidance is a kind of equipment that provides guidance for missiles in the sky on the ground and is used to mark targets.


    If you often watch movies, you will have an impression of the laser irradiating device that is similar to a large telescope in your hand when federal fourth-class marun calls for air support.


    This kind of equipment reflects the light to the laser guided missile''s guidance head in the sky through continuous laser irradiation on the target, so as to guide the missile to attack the target accurately.


    It''s just that under normal circumstances, considering the efficiency of the laser irradiating equipment when irradiating the target, this thing is usually large, and it''s normal to be like a large telescope.


    However, in front of Chen Xin''s eyes, the laser guidance module installed on the exoskeleton is not too large. It seems that it can be linked with the aiming module on the exoskeleton, removing some unnecessary optical components and reducing the volume a lot.


    Chen Xin doesn''t quite understand this thing, but he can still understand the principle of this thing.


    To put it bluntly, this is a laser launcher. It shoots laser at the target and then reflects the laser to guide the missile. Generally speaking, the principle is quite simple and crude.


    But how to ensure the accuracy of the laser guide, so that the laser can effectively guide the missile to hit the target is not simple at all.


    Moreover, the laser guidance device needs continuous irradiation to guide the missile to hit the target, so how to maintain the stable and continuous laser irradiation is also one of the important problems in the development of this kind of equipment.


    The countries that can play this laser guided missile on Bluestar, except for a few hooligans, really no small country can play this thing. Even the neighbor of Yanguo across the sea, although his economic strength and scientific and technological strength are good, also needs to import relevant equipment from their master sub Federation, and he has no manufacturing capacity.


    The laser guide module in front of Chen Xin''s eyes is specially developed for exoskeleton, but Chen Xin can also see that it should be transformed from the original laser guide, and the slot used to install optical components can be seen from some parts.


    This is also a common fault of the project prototype. After all, it''s just to make samples to verify the technology. Sometimes even the shell is simple and rough, and it''s wrapped with black tape. It won''t do more exquisite or optimize the internal structure.


    As for optimizing the circuit, adjusting the size of parts, reducing the volume and weight, it''s all the work after the technology is finalized.


    However, in Chen Xin''s case, it''s different. Through system upgrade, he can put all these steps in place in one step.


    It doesn''t cost much survival to upgrade such a laser guidance module. After playing with it in hand, Chen Xin reassembled the disassembled parts, and then ordered the system upgrade.


    For the upgrade of the laser guide module, Chen Xin did not make any major changes, just optimized the structure and improved the performance of the equipment.


    Chen Xin didn''t want to add some other functions to the laser guide module, such as laser cutting.


    However, this will make a big change to the equipment and greatly increase the energy consumption of the equipment. Chen Xin gave up this idea after considering it. After all, the function of laser cutting is not practical.


    Laser cutting is mainly used for precision machining, plus there is no tool, can carry out some angle cutting, in machining and other aspects has its unique advantages.


    However, we can''t use this kind of thing on the battlefield. After all, laser cutting can directly kick things, or even open the last grenade or door opener.


    So Chen Xin doesn''t have to bother about laser cutting. If he really wants to make a laser cutter, he should provide it to the industrial sector, not to the military as a weapon.


    After all, high-precision laser cutting instruments can be used in many fields. It is a great waste to put them on the battlefield, unless Chen Xinzao''s laser weapons are science fiction.


    But if Chen Xin wants to build a laser weapon, he just needs to build a laser gun. Why use someone else''s laser guide to transform it?Chen Xin, who was thinking about rubbing a laser gun to play, put the upgraded laser guidance module back on the table, went to one side and poured himself a cup of hot water, intending to have a rest.


    He is now in the office specially prepared for him in the military camp. The indoor temperature is 15 degrees, and it is equipped with hot water, TV and computer. Although the TV has no signal and can''t watch TV programs, it''s OK to download movies or TV programs in advance. Although the computer is a military computer and can''t be used to play games, it''s also connected to the Internet, It can be used to browse some information on the internal network.


    Not only that, this office also has matching bathroom facilities and bedroom. If Chen Xin wants to have a rest, he can take a comfortable hot bath at any time, and then lie in bed and have a good sleep.


    That is to say, Chen Xin does not want to stay in the military camp, otherwise he will enjoy better treatment.


    However, when Chen Xin was resting, he heard the sound of a large propeller coming from the outside, which made Chen Xin have to pick his eyebrows, helicopter?


    Chen Xin is not surprised that after the disaster, due to a large amount of dust and particles in the air, all aircraft have been unable to take off, unless the engine is not used, otherwise no aircraft dares to take off in such bad air conditions.


    But now he can actually hear the sound of helicopters in the military camp, which makes Chen Xin very curious. What is so important that he has to risk using the aircraft, or is it that the current weather conditions have allowed the aircraft to take off?

 Chapter 385

    Because of curiosity, Chen Xin left the office and went to the corridor outside. Because of the cold protection, there is a glass corridor outside the barracks, which can not only see the outside, but also effectively block the cold, so that Chen Xin can see what happened without going out.


    In the middle of the barracks, a huge black helicopter is slowly landing on the specially leveled snow.


    This is a large helicopter with round head and round brain, but without losing its edges and corners. The five huge rotors are gradually stopping rotating, and their huge weight and even the landing gear are trapped in the snow on the ground.


    Fortunately, the snow had been leveled in advance, and the helicopter just sank down a little and stopped steadily.


    Looking at this helicopter, Chen Xin can''t help but raise eyebrows. Although he is not a military fan, Chen Xin can recognize this zhi20 helicopter, which was only equipped with the army of Yanguo before the disaster and has a very high degree of spread on the Internet. After all, its prominent five rotor is still very characteristic.


    As a domestic helicopter very similar to the famous Black Hawk helicopter of the Federation, it was just installed in the army of the Republic of China at the beginning of the disaster. It is regarded as the new equipment of the army.


    It''s just a pity that before the army can play with its new toys, the meteorite has fallen into the sky, making the air full of dust, making it difficult for all planes to take off.


    We should know that the aircraft engine has a huge demand for air intake, but there is no such thing as air filter. If a large number of dust or particles in the air enter the aircraft engine, it is very easy to damage the aircraft engine and cause the whole aircraft to be scrapped.


    Coupled with the strong wind caused by the collapse of the weather system after the disaster and the loss of the risk of satellite navigation flight in the dark environment after the dust obscured the sky, not only large aircraft, but also small aircraft such as helicopters have never taken off again.


    But now the arrival of the zhi20 clearly indicates that Yanguo seems to have returned to its own airspace.


    This obviously makes Chen Xin a little curious. How does the zhi-20 solve the problem of dust and particles in the air? Or is the air quality ready to allow the plane to take off?


    With such doubts, Chen Xin also noticed that something seemed to be added to the air inlet of the zhi20, but the light was dim and Chen Xin could not see clearly.


    Just when Chen Xin was confused, the commissar of the special forces came in from the outside.


    "What''s the matter with this helicopter? Is the plane ready to fly now? " Chen Xin looked at the commissar and asked him curiously.


    "At present, the plane has not gone around. This helicopter is used for testing, mainly to test the new air filter installed on the plane, to see if the helicopter can fly normally with the air filter installed." The political commissar obviously understands the situation, and he came to Chen Xin just for this matter: "in addition, there are things sent for Comrade Chen Xin on this plane. In addition, I hope Comrade Chen Xin can check the air filter of the plane to see if there is anything that can be improved."


    "What did you bring me? What is it? " Chen Xin was surprised to hear that the plane in front of him came to deliver things to him.


    Although I know that I can enjoy good treatment now, it''s not a general treatment to use a helicopter to deliver materials to me!


    Compared with the close protection of the whole special forces, a helicopter obviously makes Chen Xin feel the treatment he enjoys now more intuitively.


    As for the aircraft air filter mentioned by the political commissar, Chen Xin remembered that in the previous improvement project he cooperated with the state, it seemed that there was an improvement of the air filter. At that time, Chen Xin thought that it was a new type of air filter for cars, and he once wondered why a car air filter had to do so much air intake.


    Now it seems that I misunderstood its purpose. The air filter with super large air intake is obviously prepared for aircraft.


    Chen Xin remembers that he upgraded the filtering effect and ventilation capacity of the air filter according to the requirements, and also improved the material of the air filter element to make it more durable. Needless to say, he could clean it directly by washing, which greatly improved the performance of the air filter.


    Judging from the fact that the helicopter can land smoothly, it seems that it has helped the plane return to the sky.


    Thinking of this, Chen Xin can''t help feeling excited and excited. You know, with a plane, many things will be very different.


    Take the snow disaster near the city as an example. If we could get two helicopters like zhi20 in the urban area at the beginning, the rescue team would not have to drive over at great risk.


    It is necessary to know that a straight 20 aircraft with a take-off weight of more than 10 tons can carry at least two tons of materials or one class of soldiers. According to the number and materials of the rescue team at that time, the aircraft only needs to fly several times to transport the whole rescue team and materials from the urban area to the nearby city, and it can continuously transport medical staff and rescue materials from the urban area to the nearby city .


    It''s much more convenient to transport people and materials from the urban area to the city than it is now.What''s more, if the helicopter can take off normally, the connection between different places will become closer again, and both material transportation and information transmission will become more efficient and fast.


    In addition, the new communication network that the state plans to build is enough to restore the state''s control over local areas to the level before the disaster, so that the whole country can return to a whole and play a more powerful role.


    "Go and have a look!" At this time, Chen Xin could not restrain his mood. He went back to his room and put on his protective clothing. He left the barracks with the political commissar and stepped on the snow to the apron.


    At this time, the engine of the zhi20 helicopter has stopped completely, and a white gas can be seen on the shell of the engine. At the same time, a layer of frost is quickly formed.


    But this does not affect the power and handsome appearance of the zhi20 helicopter, on the contrary, it adds a different momentum.


    "Are you Comrade Chen Xin? Hello, here is a special material for you. Please sign for it Next to the plane, a man in the uniform of an air force pilot took out a document and handed it to Chen Xin for his signature.


    Chen Xingang had just heard the political commissar mention this, and naturally he was not surprised.


    He took the document and opened it. Chen Xin''s eyebrows flew up: "these things are too..."

 Chapter 386

    What Chen Xin brought by helicopter is not strange, but the radioactive element materials he asked for from scientific research institutions.


    However, Chen Xinyao''s radioactive element materials are different from those previously used to make isotope thermoelectric batteries, because they are a batch of weapon grade enriched uranium with more than 90% uranium 235.


    And the weight from the helicopter is enough to build a 100000 ton tactical nuclear bomb.


    If it is before the disaster, or under normal circumstances, it is absolutely impossible for the state to hand over so much weapons grade enriched uranium to individuals. Even experts studying nuclear weapons must be subject to strict supervision before they can have access to these nuclear materials.


    But now, unlike in the past, Chen Xin has shown his value to the country, and has shown that he has the ability to use these nuclear materials, and has put forward the justifiable reasons for using these weapons grade enriched uranium. Only when the country agrees to give these weapons grade enriched uranium to him.


    Even so, along with this batch of approved raw materials came another order, which was directly given to the commander of the special forces in front of Chen Xin.


    That order requires the special forces to supervise the use of these nuclear materials while protecting Chen Xin. In case of loss or leakage, the special forces will control the situation at all costs.


    Although Chen Xin was not targeted in the order, he could still hear that if he really intended to do something bad with these approved materials, the special forces who were originally protecting him would point their guns at him.


    Chen Xin doesn''t care about this situation. After all, it''s the raw material that can build a 100000 ton tactical nuclear weapon. Even if Chen Xin doesn''t use it to make a big bomb, he just makes them undergo fission reaction. If something goes wrong, it will be the next Chernobyl or Fukushima.


    In such a situation of high threat, these special forces as a safety valve to restrict Chen Xincai''s normal operation. No matter how much the country trusts a person, there will still be some security measures.


    As for why Chen Xin needs this kind of weapon grade nuclear material, it is because he wants to build a small high-power nuclear fusion furnace.


    If you are familiar with the design of Golder''s works, I''m afraid you can understand that the so-called nuclear fusion furnace is the power source of Golder.


    This kind of thing can be made theoretically, but it is not so easy to realize technically, otherwise small nuclear reactors will not be so difficult to produce, and controllable nuclear change is still in the stage of theoretical improvement.


    However, this is not a problem for Chen Xin. He is sure enough to create what he needs.


    As for why he was surprised by the list of documents sent, it was because there was a special supply along with the nuclear materials.


    Frozen fresh vegetables, fruits, beef and mutton, as well as milk and eggs


    If these things arrived before the disaster, they would not be too exaggerated. They are only of high quality, which ordinary people may not be able to buy or see.


    But in today''s environment, these things are very luxurious and precious.


    Especially beef and mutton, people may be hungry, where to feed cattle and sheep? Even if cattle and sheep can only eat grass, the problem is that it is unrealistic to get a lot of grass in this environment.


    It can be seen that this batch of materials is really special.


    "These materials are the treatment you should enjoy for Comrade Chen Xin. Your contribution to the country is not commendable with just a little food. These things only enable you to eat well and have more energy to contribute to the country." The pilot who came to deliver the supplies was obviously told before he came, and he specially explained it to Chen Xin.


    Hearing what the pilot said, Chen Xin thought it was a bit exaggerated, but after scratching his head, he was very happy to accept these things.


    As the pilot said, it''s just a little bit of food, which is nothing compared to having a whole special forces force to protect themselves.


    Moreover, in terms of Chen Xin''s contribution to the country, it is entirely possible to enjoy these things, or even better things.


    So he accepted it with peace of mind, and let the commissar of the special forces help him put these things away.


    As for the nuclear raw materials delivered with the materials, we need to take them seriously. Although the radiation dose of these weapons grade enriched uranium is very small before the chain reaction begins, and it can be completely exposed without protection, we must pay special attention to the transportation and storage.


    The commander of the special forces even called a combat team to take charge of the safety of these nuclear materials. Among them, Chen Xin''s eyes could be seen from the heavy machine gun and small caliber machine gun carried on the exoskeleton of the heavy firepower.


    Is it OK for these heavy weapons originally used for anti vehicle to directly use individual equipment to hit people with the help of exoskeleton?


    Just as Chen Xin watched these special forces move away the nuclear materials, the pilot came to Chen Xin and said, "Comrade Chen Xin, there is another thing I want you to do for me. Do you think it''s ok?""What''s the matter?" Chen Xin turned to look at the pilot, a little curious about what he had.


    "The thing is, our plane is used to test the new air filter, which you have improved before. This time we fly here to test the performance of the new air filter, so I want to ask you to see if there is anything that needs to be improved." The pilot said, then pointed to the straight 20 behind the engine intake, where the new air filter is installed.


    Hearing what the pilot said, Chen Xin nodded after picking his eyebrows: "it''s a piece of cake, but I need to take things down. Will it affect your mission?"


    "No, no, our task is to test the effect of the new air filter and send things to Comrade Chen Xin. There is no strict limit on the return time." Hearing that Chen Xin was willing to help, the pilot quickly explained, "and if we really need it, we can also contact the superior through the communication equipment to explain the situation, which will not delay the mission."


    "Well, you wait for me, I''ll get the tools." Chen Xinjian''s pilot said so, but he didn''t say anything more. He just went back to the office and put out his power armor.


    Wearing power armor, he went to the side of zhi20. Chen Xin pointed to the air inlet of the engine and said to the pilot beside him, "come here and help me. I want to take things down first."


    Then he opened the mechanical arm and began to remove the air filter installed on the air inlet of the straight 20 engine.

 Chapter 387

    Helicopter equipped with air filter is a kind of black technology.


    After all, before that, no aircraft in the world would install an air filter on its own intake duct, which really affected the air intake.


    However, with the powerful function of system upgrading, Chen Xin has developed an air filter that can be installed on a helicopter, so that the helicopter can fly with an air filter.


    "After installing the air filter, will the dynamic performance of the aircraft be affected?" Chen Xin put the two air filters removed from the zhi20 on the table and asked the pilot beside him as he took them apart.


    "There is a certain impact. The intake air does have a certain attenuation compared with before, but on the whole, it can still meet the flight needs, only the engine power is lower than before, and the load needs to be adjusted." The pilot reported the situation to Chen Xin, and also told Chen Xin about the changes of aircraft performance parameters after the installation of air filter.


    After listening to the pilot''s introduction, Chen Xin nodded clearly: "it seems that the installation of air filter still has a great impact on the engine''s air intake. Although it is not impossible to fly, it also has a great impact on the engine power. Without moving the engine, we can only continue to improve the air filter or enlarge the intake duct. "


    "If you enlarge the intake duct, it will affect the structure of the aircraft, right?" Naturally, the pilot is also knowledgeable. When Chen Xin said that he wanted to improve the air culvert, he was worried that it would damage the aerodynamic layout of the aircraft.


    "It may have a certain impact, but it can be adjusted and it won''t get in the way." Chen Xin doesn''t care about this, and what he says seems to be understated.


    Enlarging the air inlet duct does not affect the aerodynamic layout of the aircraft. This will be a big project for a normal aircraft designer, even equivalent to redesigning the whole aircraft. But for Chen Xin, who holds the system in hand, this is really nothing.


    While studying the disassembled air filter, Chen Xin suddenly asked the pilot curiously, "how did you come here when it''s so dark without satellite navigation?"


    "If there is a positioning instrument on the plane, you can still determine the position. If you use it with an altimeter, there will be no risk of being lost." It''s easy for pilots to say, but only they know the danger and difficulty.


    Night flight itself is a very difficult challenge. Before the disaster, with satellite positioning, tower guidance, air control and many other auxiliary conditions, night flight seems not so difficult. Anyway, it''s just to fly according to the preset data. After all, there is no reference when flying high. Everything depends on various flight auxiliary systems on the plane, and even can turn on the automatic control Pilot, let the pilot have a rest.


    But with the loss of these things, flying has become a very dangerous thing in the past that tests the level of pilots.


    After losing the modern auxiliary means, there is not much difference between today''s aircraft flight and World War II, except that today''s aircraft is more advanced, with the help of computer. Compared with World War II pilots who can only calculate their own position by compass and watch, today''s pilots can intuitively read from various instruments on the aircraft The exact location of the target.


    However, this does not reduce the risk of night flight, especially in the case of low visibility, where there is almost no reference object on the ground, and the helicopter''s flying altitude is not high, it is likely to hit the mountain and cause disaster.


    Under such circumstances, the pilot is really risking his life to fly the helicopter here. It''s really amazing.


    "Anyway, it''s very dangerous!" Chen Xin sighed and admired the pilots.


    "How can soldiers fear danger?" The pilot seems to have been aware of this for a long time, and did not show any emotion: "since he has chosen to be a pilot, he has already thought about the danger he will face."


    Hearing what the pilot said, Chen Xin couldn''t help looking at him deeply, but didn''t say anything more. He just turned his attention to the air filter in his hand, and then upgraded it with the functions of the system.


    "I have made some adjustments to this air filter, which should improve the air intake. You can test it when you go back. After you go back, let the professional technicians have a look. If you have any problems, you can call me at any time." Chen Xin handed the upgraded air filter back to the pilots and helped them install it on the helicopter.


    The pilot saluted Chen Xin and said, "thank you for your help. Let''s go first."


    Perhaps because of the military''s poor words, although the pilot expressed his thanks to Chen Xin, he didn''t say much, but his thanks to Chen Xin were sincere.


    "Bon voyage." Chen Xin didn''t mind. He laughed at the pilot and watched him get on the plane, restart the plane and set off a gust of wind.


    Back a few steps, back to a safe distance, watching the helicopter''s propeller rolled up all over the snow, and then gradually pulled up and disappeared in the night sky.


    "If we can get the plane back in flight, then life will be much better in the future." Looking at the helicopter flying away, Chen Xin couldn''t help sighing."Helicopter may not be a big problem, but is that kind of big jet OK? The air intake problem of large aircraft engine is much more serious than that of helicopter engine, isn''t it One side of the commissar heard Chen Xin sigh, suddenly curious to ask him.


    Compared with helicopters with limited carrying capacity, fixed wing aircraft is the real focus. After all, civil aircraft, transport aircraft and military fighters are all fixed wing aircraft, and their engine intake is more huge, especially for large aircraft. While several engines bring huge lift, the demand for air is also extremely amazing.


    But if we can solve this problem and let large aircraft return to the sky, it will bring amazing changes to the current situation.


    "For large aircraft, consider the traditional propeller aircraft first. Their engine intake is not as exaggerated as that of jet aircraft. They can still fly with air filter, and if necessary, they can be electric." Chen Xin is still thinking about this, but he has no good idea about jet aircraft: "as for jet engine If the air quality is not greatly improved, it''s better to consider redesigning. The air filter can''t meet the flight needs. If a sound barrier is broken, the air filter will be broken. "


    Although not all jet aircraft can break through supersonic speed, it is obvious that the supersonic fighter in the army is the key to solve the problem.


    However, Chen Xin can''t help him with this. If he gives him an aero-engine, he may be able to transform it into an engine that can be used in today''s environment, but it''s not very necessary.


    Because the dust in the air will only affect the flight temporarily. As the dust gradually falls, when the air quality meets the flight requirements, those jet planes can naturally return to the sky. There is no need to redesign an engine to meet the short-term needs.


    After all, you can''t fly, so can other people.

 Chapter 388

    Seeing off the pilot, Chen Xin naturally turned his attention to the weapons grade enriched uranium.


    This is really a good thing, and it''s also a big killer.


    There are only a few countries in the world that can produce this kind of enriched uranium of weapon grade purity. Small countries have no scientific and technological strength and industrial strength to study related technologies.


    Coupled with the control and blockade of nuclear technology by the five rogues themselves, it is even more difficult for small countries to have the opportunity to study and manufacture such weapons grade nuclear materials.


    If it is put before the disaster, such a batch of nuclear materials that can produce 100000 tons of equivalent tactical nuclear bombs is very valuable. Although the cost of a kilogram of weapon grade enriched uranium is about 500000 US dollars, in fact, there is no market at all. Let alone idle people, idle countries can''t buy it.


    Before the disaster, if anyone could resell such a batch of nuclear raw materials, it would be hard to say if they could make money, but at least they could not spend so much money in their lifetime.


    If Chen Xin is not in Yanguo, a nuclear power, and the country has the ability to manufacture nuclear weapons and nuclear raw materials, he can''t easily get access to this level of nuclear raw materials. Instead, he can consider buying some uranium ore to purify himself. After all, before the disaster, uranium ore was only controlled, and the price was not expensive.


    But now thanks to the state''s blessing, Chen Xin has obtained this batch of weapon grade enriched uranium. Naturally, there is no need for Chen Xin to slowly purify the uranium ore and make his own enriched uranium.


    The reason why Chen Xin needs to enrich uranium is to build a fusion reactor.


    Some people may wonder how enriched uranium, which is clearly the raw material for fission reaction, can be used to build a fusion reactor?


    This is not Chen Xin''s mistake, or his plan to upgrade the fission furnace into a fusion furnace by means of the system. Instead, it is possible to build a fusion reactor through the fission furnace.


    Before explaining how to do this, we need to know that the fuel for fusion reaction is usually the isotopes of deuterium and tritium. Although deuterium is abundant in nature, tritium needs to be produced artificially.


    The way to produce tritium is to bombard lithium-6 compound target with neutrons produced by fission reaction, and tritium can be obtained in large quantities.


    After that, we only need to enrich tritium to more than 99% by thermal diffusion method, then we can use fusion reaction.


    Of course, what we can get by doing this directly is a violent thermonuclear fusion reaction, which is usually called hydrogen bomb explosion, releasing huge energy in an instant.


    Therefore, all the countries that have the ability to study nuclear fusion are looking for ways to control the nuclear fusion reaction, which is the origin of the idea of controllable nuclear fusion and cold nuclear fusion.


    It''s not difficult for Chen Xin to achieve controllable nuclear fusion and cold nuclear fusion by holding the system in hand. Even if he is willing to toss about, he can get science fiction power sources such as GN solar furnace and antimatter reactor.


    But of course, what Chen Xin wants is not something black and irrelevant, but something that can be copied and promoted.


    So he doesn''t plan to get too black technology, even cold fusion, but a controllable hot fusion reactor.


    For this thermonuclear fusion reactor, Chen Xin''s idea is not to add fuel to the reactor by injecting fuel from the outside, but to install a fission reactor under the fusion reactor, which directly bombards the target material with the fission reactor to produce tritium and supply the fusion reactor as fuel.


    That''s why Chen Xinhui needs nuclear materials. Otherwise, even if he can make a furnace, it won''t burn without fuel.


    As for why we don''t use fuel grade enriched uranium but use weapon grade enriched uranium, it is because according to Chen Xin''s idea, he needs to use high-purity nuclear materials as fuel.


    "Seriously, it''s a bit numb to see so many nuclear materials piled up in front of us." In the warehouse where nuclear materials are temporarily stored, Chen Xin looks at the box in front of him for storing nuclear materials and the huge nuclear radiation sign on the box. He really feels numb in the back.


    "Weapons grade enriched uranium with more than 90% purity will not kill many people if it flows out." As the commander of the special forces, he has carried out many dangerous tasks. Naturally, he can understand how dangerous this thing is and how many people will risk their lives for it.


    "So please take care of it. Before I build the reactor, I can''t lose a gram of these things." Chen Xin looked at the commander, his face turned to serious: "these nuclear materials will be temporarily stored here, and then I will continue to work in Linshi. After the work here is completed, these nuclear materials will return to my own refuge with me, where I will complete the manufacturing and loading of the nuclear fusion reactor, and then carry out the test run. The whole process of security tasks will be completed It''s up to you. "


    Chen Xin''s words made the commander of the special forces look awe inspiring. Although he had been called by the superior leaders before the departure of this mission, and he was psychologically prepared, Chen Xin let him guard these important and dangerous nuclear materials, but still let the commander breathe in a hurry.


    But as a soldier''s sense of mission and responsibility, he almost instinctively replied to Chen Xin: "guarantee to complete the task!""This is an extra trouble I brought to you. Originally, you only wanted to protect my safety, but now you have to be responsible for the safety of these nuclear materials." Chen Xin also knows that he has brought troubles to others, but these troubles are inevitable.


    After all, it''s weapons grade nuclear material. The state can''t just hand it over to Chen Xinji. If the special forces hadn''t been ordered to protect him, I''m afraid the state would not have handed over weapons grade nuclear material to him so easily.


    Therefore, this special force has been shouldering the task of protecting the safety of nuclear materials and Chen Xin''s next fusion reactor since they started.


    Fortunately, in the current environment, it is not too much trouble to protect the safety of Chen Xinhe''s batch of nuclear raw materials. As long as we keep the barracks well and ensure that the batch of nuclear raw materials do not flow out, there will be no problem.


    After all, in the land of Yan state, there is no force that can break the barracks guarded by an elite special forces, and can rob things from the barracks.


    "The existence of this batch of approved raw materials should be blocked as far as possible. The less people know about it, the better. I''ll ask you for all this." Chen Xin didn''t know how to do it, but he put forward his own requirements to the commander according to his impression.


    The commander also nodded to this, and replied in a positive way: "it''s true that the less people know about this kind of thing, the better. After that, I will explain it to the soldiers in charge of security and let them keep it secret."

 Chapter 389

    With the efforts of Cao Daren and the workers, the pipelines connecting the two heat supply hubs were finally laid. Although they encountered some problems in the construction, they quickly solved these problems and made the pipeline successfully completed in a short time.


    In order to build the heating hub as soon as possible, the municipal government has invested considerable manpower and material resources in this matter.


    It not only provided sufficient manpower support for the project, but also specially sent all the construction equipment available in the city to the construction site.


    Only when several construction points are constructed at the same time can the whole pipeline be completed faster than expected.


    After the completion of the construction, the two heating hubs were finally able to operate at full power without hindrance, but the heating field could be completely expanded.


    Because the heating field on the side of the railway station has been started before, after the completion of pipeline construction, the heating field soon reached the maximum range, digging the whole railway station out from the snow.


    With the railway station re exposed to the ground, the supply of materials in the city has finally returned to normal.


    At last, the municipal government did not need to organize a large number of labor force to load and unload materials every time the goods and materials were transported by train.


    After the railway station re exposed to the surface, the loading and unloading station originally planned by Linshi municipal government will naturally continue to be constructed. After the completion, the loading and unloading capacity of Linshi materials will be further improved, and more labor force will be liberated, which can be put into the post disaster reconstruction of Linshi.


    After seeing the benefits of the heating hub, the municipal government has naturally increased the investment in this area.


    Cao Daren was not only employed as the head of the municipal government''s engineering team to be specially responsible for the construction of the heating hub, but also set up several construction teams. With the help of Professor Zhang, the geological exploration team, after determining the construction points of other heating hubs, the project started rapidly at the same time, intending to completely spread the heating network in the city.


    Chen Xin, of course, is happy with this. He not only made an electromagnetic metallurgical furnace to make parts for the newly added heating hub, but also enthusiastically invested in it, helping the engineering team to install and debug the heating hub on the construction site.


    More importantly, he also improved the drawings again and upgraded the already built heating hub to make the heating hub more efficient and consume less.


    Because of what Chen Xin has done, the situation in Linshi has changed greatly.


    When Chen Xin and Chen Xin arrived in Linshi, the whole city was paralyzed. Although the municipal government was still trying to improve the situation and struggled to carry out the post disaster rehabilitation work, if there was no external intervention at that time, Linshi would only usher in a lot of deaths when the medical system had collapsed, and the whole city would be in a desperate situation.


    However, now, the rescue station established by the rescue team has effectively curbed the deterioration of the city''s medical situation. With more and more mild and moderate patients recovering and the serious patients getting better, the pressure of the whole medical system is also getting smaller and smaller, and it can be effectively operated again, which has greatly improved the health condition of the city.


    In addition, the situation in the railway station has improved, the handling of materials is normal, and the supply of materials in the city has been effectively guaranteed. The situation in all aspects has finally made a good change and improvement. It can be said that the city has finally got rid of the previous disaster, completed the rehabilitation work after the disaster, and can be rebuilt after the disaster.


    Obviously, the heating network formed by heating hub is one of the key points of post disaster reconstruction.


    It is very important for Linshi to have a heating network that can provide effective heating and enough geothermal energy for power generation. Once it is completed, it will provide a bright future for the city. Therefore, it is understandable that Linshi municipal government has invested all the things that can be invested in this plan.


    For Chen Xin, the main purpose of his coming to the city is to make the temporary situation better and get everything back on the right track. Now the situation of the temporary market does not need him to do more, and it will become better and better. Chen Xin has no need to stay.


    After the construction of the heating hub, the heating network he envisioned has a rough rudiment. The next step is to increase the number of heating hubs to form a real network.


    However, this is a kind of repetitive work. After the state has sent relevant technical personnel, it is natural for them to be responsible for the work instead of Chen Xin himself.


    However, for Chen Xin, he still has one thing to do, that is, the initial idea of the whole heating network, the construction of the energy tower.


    The energy tower is different from the heat supply hub. No matter the equipment volume, drilling depth, heating efficiency or manufacturing investment, it is much larger than the heat supply hub. Therefore, its construction is not as easy as the heat supply hub, and it needs to invest more energy.


    For this reason, Chen Xincai did not leave Linshi immediately. Instead, he planned to complete the construction of the energy tower and leave Linshi after the construction of the whole heating network.


    "The design of the heating hub has been very perfect. As long as it is spread out, it can help many people and many cities. For Linshi, it only needs to build more energy towers. Why do you have to work hard to build such a large energy tower?" Has moved to the melting snow of the railway station square camp, Cao Daren puzzled to Chen Xin asked.In his view, the heating hub is already a very practical and perfect thing. It is already perfect to use underground hot spring water for heating. There is no need to build any large-scale energy tower and drill thousands of meters deep underground wells to extract deep geothermal energy.


    "No, no, the meaning of the two is quite different!" The retort is Professor Zhang, who retorted to Cao Daren: "the heating hub is indeed a very good technology, but this kind of shallow buried and easy to develop hydrothermal geothermal resources is not widely distributed in China, and the reserves are limited.


    In some areas with rich traditional geothermal resources, it is indeed worthy of promotion and application, but for some areas lacking shallow geothermal resources, especially in areas lacking groundwater resources, the application of this technology is very limited.


    But the energy tower technology is not the case. The distribution of deep geothermal resources in China is far more extensive than that of shallow geothermal resources, and the reserves of dry hot rock resources in China are also very rich. If it can be exploited and applied on a large scale, it will be of great benefit to China''s existing energy structure and improve the current situation of the country


    "This..." Cao Daren was temporarily speechless. He really couldn''t understand Professor Zhang''s great principle. However, Professor Zhang said that the energy tower was very important. He still understood it, so he nodded and said, "how can the energy tower be built?"

 Chapter 390

    How to build an energy tower? I''m afraid only Chen Xin can answer this question.


    According to the prior design, the most important thing is, of course, to drill a deep well directly underground to exploit the deep geothermal resources.


    In addition, considering the problems of reuse and the medium through which geothermal energy should be transmitted, another deep well with the same depth should be drilled to transport water or air back to the ground.


    Therefore, a total of two deep wells can not be less.


    As for the main body of the tower on the ground, this is relatively simple.


    After having the experience in the construction, design and use of the heating hub, even if Chen Xin didn''t do it himself, other engineering and technical personnel can design the main body of the energy tower, although the effect may not be as good as Chen Xinqin''s.


    "So to build an energy tower, it''s the same as drilling a well first." Chen Xin looked at Cao Daren. Now Cao Daren is the leader of the construction team of the heating hub in Linshi. Of course, the work of drilling wells should be handed over to him.


    "But I should have talked to the writer about that, right? I don''t have a suitable rig and I lack experience. How do you solve this problem? " Cao Daren''s answer was the same as before. He didn''t have a drill to drill thousands of meters underground, and he couldn''t take the job.


    Chen Xin had heard Cao Daren say this before, and naturally thought of a solution: "don''t worry about the drilling rig. After the normal loading and unloading of materials is restored at the railway station, I have already reflected the situation to their superior departments through people from the scientific research department. Later, a deep well drilling rig will be sent to Linshi, and there will be one with deep well drilling experience "We need not worry about this problem," he said


    "Oil drilling team? They''re very experienced, aren''t they? " When Cao Daren heard that Chen Xin had prepared the drilling rig and drilling team, his face was suddenly a little unnatural.


    Compared with the professional oil drilling team, Cao Daren is just a well digger. There is a gap between the two in terms of experience and technology. Cao Daren has a feeling of worrying about gain and loss, and thinks that the emergence of this team will replace him.


    Chen Xin didn''t notice Cao Daren''s mood change, but said to him, "when the drilling rig and drilling team arrive, the deep well drilling work can start. When the time comes, you can cooperate with them."


    "OK, I see." Cao Daren didn''t say anything more in front of Chen Xin. He just nodded, but he had already turned several thoughts in his heart.


    "Another is the selection of drilling sites. Please work hard on your side, and try to select the drilling sites as soon as possible. When the drilling rig comes, you can start drilling directly." Chen Xin looked at Professor Zhang and asked him: "in addition, we have little experience in how to exploit deep geothermal. If there is any deficiency, please give me more opinions and suggestions, so that I can know how to improve."


    "Don''t worry, the old man can do some of these things, and won''t delay things!" Professor Zhang laughed and agreed.


    Chen Xin nodded slightly. Seeing that the matter had been finished, he said to them, "in that case, let''s do it. I have other things to do. Let''s go first."


    With that, Chen Xin left the meeting camp and headed for the military camp.


    Seeing Chen Xin leave, Cao Daren and Professor Zhang look at each other. Suddenly, Cao Daren asks Professor Zhang, "what is the writer doing recently? It seems that he has been staying in the barracks all the time. He is very busy every day and doesn''t come back to bed until very late. "


    Cao Daren is just curious, but some want to explore what Chen Xin is doing in the barracks, so that he can mobilize a lot of resources.


    It''s hard for Cao Daren not to be curious that a drilling rig capable of drilling deep wells and an oil drilling team can not be mobilized at will, but Chen Xin can come as soon as he opens his mouth.


    "Who knows? We should inquire less about matters related to the army and state secrets. The less we know, the better. " But Professor Zhang shook his head directly. After finishing the map on the desk, he was ready to leave. When he came to the door, he stopped and said to Cao Daren, "it''s better not to know some things. Do your job well and don''t expect things you shouldn''t expect."


    With that, Professor Zhang walked out of the room, but Cao Daren''s expression became hesitant and hesitant.


    In the barracks, outside Chen Xin''s room are two special forces armed with heavy weapons.


    Their original exoskeleton has been upgraded by Chen Xin, and now it has become something like the heavy-duty mecha in "call of duty 11".


    The fully covered armor is firmly wrapped around their bodies, and the chest part restores the design in the game. Two heavy armor plates are added as the defense shelter.


    The right shoulder is a 12.7mm Gatling machine gun, which is connected by a mechanical arm on the back. It is usually mounted on the back. When it needs to be used, it will stretch to the front and be held by the right hand. It is controlled by the direct connection with the helmet''s aiming system. The firing rate of 1200 rounds per minute is fierce enough to tear all light units in the battlefield.The right shoulder is equipped with two 57mm rocket launchers, which can launch a total of 12 57mm rockets. It is common to the small caliber aviation rocket ammunition currently equipped by the military. It can also kill heavy vehicles such as tanks.


    Although it seems to be equipped with few weapons, these two kinds of weapons are enough to make this kind of heavy mecha incarnate the most fierce individual war machine in the battlefield.


    What''s more, Chen Xin also installed a folding mortar on the left leg of the mecha. When using it, he only needs to kneel on one knee to set up the mortar to provide artillery support for the battlefield. At the same time, he can hold the machine gun with his right hand to protect himself from the fire point.


    Chen Xin has transformed five of these heavy-duty mechas, two of which are used to guard his office, while the other two are used in the warehouse where nuclear materials are stored. They are used by four special forces in turn, to ensure that people and machines will not stop and provide 24-hour uninterrupted protection.


    As for the last one, it has been taken away by the helicopter that came to the camp for the second time and handed over to the researchers of the military industry system to reverse crack and prepare for imitation.


    Under such strict protection, Chen Xin''s work is actually very good. He is carrying out the drawing design of the fusion reactor, and is trying to build a miniature reactor to verify the rationality of his proposed structure.

 Chapter 391

    In the eyes of many people, it may be much easier to make a model than to make a complete thing.


    After all, the model is so small that it doesn''t take much material or effort.


    But people who have made a model, especially those who have made a 1:1 completely real model, will tell you that it is sometimes more difficult to make a model than to make a real one.


    Because it''s easy to make a small thing big, but it''s hard to make a big thing small.


    Although what Chen Xin wants to do is a miniature nuclear fusion reactor, his technical requirements are not lower than that of building a large-scale reactor at all, and even his requirements for the machining accuracy of parts are higher than that of a large-scale reactor.


    Although the requirements of large-scale nuclear fusion reactor are strict, the tolerance of large-scale equipment still has a certain margin, but when you reduce the equipment in equal proportion, the original tolerance margin will also be reduced.


    For example, in large-scale equipment, the error of ¡À 5 may not exist in the model of equal scale reduction, and the smaller the model, the more so.


    Especially when you have to completely restore the structure and function of large-scale equipment, the smaller the machining accuracy, the higher the requirements of the parts. In many cases, the cost is many times higher than that of the parts required by large-scale equipment.


    For a simple example, in the existing nuclear fusion reactor technology, the structure of magnetic confinement nuclear fusion device to block neutrons and plasma, prevent high-energy hydrogen ion splashing and serve as heat exchange in the future is called the first wall. In the material selection of nuclear fusion reactor, this first wall has very high requirements.


    In reality, the first wall can be processed to a certain thickness to block neutrons. However, when the scale of the model is very small, the thickness of the first wall will become thinner. In this case, if we want to continue to block neutrons, we have higher requirements for it.


    Especially the first wall itself is a consumable, with the neutron bombardment of the first wall, its surface will bubble!


    Large equipment can rely on the thickness to extend the service life, regular replacement to avoid the first wall being penetrated.


    But for a small model, it''s very deadly. After all, it''s impossible to say that the reactor will stop and change consumables after a few revolutions, right?


    This is also the reason why the current nuclear fusion device is becoming bigger and bigger. Because of technical reasons, only by making the device bigger can the expected performance be achieved, so as to realize the ignition of nuclear fusion.


    However, what Chen Xin wants to do is just a model for verifying technology. If it''s not too exaggerated, he even wants to make a model as big as a table.


    But in the end, he made a compromise with reality. Instead of building an iron man led lamp, he built a miniature reactor about one person high.


    Although it is a miniature reactor with the same model, the structure and function of the nuclear fusion reactor previously conceived by Chen Xin can be reproduced on this miniature reactor, and it can really ignite and react, and the reaction can be controlled, and it can continuously and stably output energy.


    To achieve this, it is obvious that there are very strict requirements on the materials and technology for manufacturing this micro reactor.


    Fortunately, Chen Xin''s drawing is a product after the system has been upgraded, and the tools he uses to make parts are also the mechanical arm and worktable produced by the system, so there is no problem in terms of machining accuracy and part quality.


    As for the materials used to make the micro reactor, Chen Xin chose to obtain some of the core parts by upgrading the system, while other parts were obtained from the national scientific research department. After obtaining the materials, they were processed by the workbench and manipulator. As like as two peas,


    did not only make a small upgrade to his own arm, but also made a similar drawing in the office of the camp, and had the function of drawing, scanning and upgrading in the office of the shelter in order to process these parts. Chen Xin did not only make a small upgrade to his own arm.


    Because of this, Chen Xin was able to upgrade the drawings of the heating hub, the energy tower and the nuclear fusion reactor.


    After upgrading the drawings, not only the technical design was optimized, but also the parts were optimized. The requirements of the drawings specially adjusted the upgrading direction for the parts were simplified and the difficulty was reduced, and Chen Xin''s idea of manufacturing a micro reactor verification technology was realized.


    Because it''s just a micro reactor, it doesn''t need a lot of related materials, and some rare materials are used in a small amount. So when the helicopter came for the second trip and pulled away Chen''s newly upgraded heavy mecha, it also brought the materials he needed.


    It has to be said that after the aircraft regained its flying ability, at least the transportation became much more convenient.


    After Chen Xin got the materials sent by air express, he directly started the manufacturing of the micro reactor. However, because there are other things to deal with, he basically goes to deal with other things in the morning every day. In the afternoon, he comes to the military camp to manufacture the parts of the micro reactor, and goes back to sleep at night.


    In fact, to a large extent, this kind of regular work and rest is easy to be understood by people. Whether it''s kidnapping, assassination or tracking, it''s easy to find flaws and opportunities.


    But fortunately, more than half of Chen Xin''s time is spent in a military camp with a whole Special Force stationed. When he goes out, he just walks to a camp less than 100 meters away, and there is a combat team to escort and protect him all the way. There is enough guarantee for his safety.Under such circumstances, Chen Xin''s manufacturing work on the micro reactor was also carried out smoothly. Various precision parts were manufactured and then assembled.


    Soon, the fission furnace part of the micro reactor was completed.


    Compared with fusion reaction, fission reaction is undoubtedly much better controlled. In addition to people''s years of research on nuclear fission technology, a miniature fission furnace is not very difficult to make.


    Of course, this is not difficult for Chen Xin. For others, it is still a very difficult thing.


    Because the smaller the reactor, the higher the enrichment of the required nuclear fuel, and the higher the control requirements for the reactor, the higher the difficulty and cost of manufacturing.


    And don''t confuse radioisotope batteries with nuclear reactors. They are two different things in principle.


    Radioisotope battery itself is not nuclear reaction, it is just the use of radioisotope released by the rays with heat energy, heat energy into electric energy.


    However, the nuclear reactor uses the energy released by the material during the nuclear reaction to generate heat and convert it into electric energy. There is a big difference between the two in terms of volume and efficiency.


    Chen Xin is able to make isotope thermoelectric cells, but this is the first time to build small nuclear reactors.

 Chapter 392

    "Fission reactor ignition preparation, countdown 3, 2, 1! Start Although only Chen Xin and the political commissar and commander who came to watch Chen Xin start the reactor were in the room, Chen Xin still counted down and pressed the start button of the reactor.


    As Chen Xin pressed the button, the reactor in front of him, which was more than two meters high and more than two meters wide, and looked like two round cakes stacked together, began to enter the operation state, making a buzzing sound.


    The political commissar and commander on one side were very nervous, with a feeling that they did not dare to go out. Although they were all experienced soldiers, it was the first time for them to start the nuclear reactor. In addition, because of the modern human awe of nuclear energy, their psychology at the moment was also somewhat subtle.


    Fortunately, this technology has been put into practice for a long time. Although the small nuclear fission reactor is amazing, it is still acceptable.


    But the fusion reaction furnace is different. Not to mention that human beings have not mastered the technology of controllable nuclear fusion, the most well-known fusion reaction product is the sun which has been hanging over human head, but is now covered by thick dust.


    The simple point of fusion reaction is to confine the energy of a star to a small container and harness its energy enough to destroy everything.


    Why do mortals bind the sun? Even in mythology, there has never been such a legend.


    Even if we look at all the myths and legends in the world, I''m afraid only the ancestors of Yan people have the story of Hou Yi shooting the sun as a mortal challenging the sun.


    Now, is the power of a sun bound in this little machine?


    Although the two people who stand aside and watch Chen Xin busy know that this is not a real sun, and the gap between the sun and the star is also between the dust and Mount Tai, the energy it can release is still amazing, and the temperature that thermonuclear fusion can reach is still the same as that of a star.


    Can Chen Xin really control it, confine the stellar temperature in this small machine, and safely control the power comparable to hydrogen bomb explosion?


    In case of any danger, if this thing explodes, it should be comparable to a nuclear explosion, right?


    Before Chen Xin, although all countries in the world were studying controllable nuclear fusion, no country or scientific research institution had developed a truly stable controllable nuclear fusion device. Chen Xin''s micro reactor was the first in the world.


    If there is really an unpredictable situation, should we rush to rescue the equipment first, or should we send Chen Xin, a "scientific researcher" of great significance to the country, to a safe place first?


    The same idea appeared in the mind of the commander and Commissar. They looked at each other tacitly and soon had a clear division of labor.


    If there is an accident, one person will rush up to rescue the equipment as much as possible to prevent the reactor explosion, while the other person will take Chen Xin away at the first time and send him to a safe place.


    Chen Xin didn''t notice the communication between the two soldiers behind him. At the moment, all his spirit and attention were focused on the reactor in front of him.


    Although this reactor was built with the help of the system, and the reliability of the system has been proved for a long time, Chen Xin is still a little nervous. After all, this is a nuclear reactor. Even if it is just a micro reactor, the consequences will be unimaginable in case of accidental leakage or explosion.


    And most importantly, before Chen Xin built the reactor, no one had tried to combine fission and fusion reactions.


    Therefore, no one knows what terrible consequences a fission reactor and a fusion reaction will have if they go wrong.


    Under such circumstances, how dare Chen Xin relax?


    Fortunately, the products produced by the system are very reliable. The micro reactor in front of us has been operating normally. Tritium has been produced in the fission reactor, which is being enriched and transported to the fusion reaction chamber for fusion ignition.


    Looking at the fuel filling amount on the monitoring screen rising bit by bit, Chen Xin was also nervous.


    "Fusion reaction is ready to ignite. Who wants to press this button?" In order to ease his tension, Chen Xin turns to the commander and commissar behind him and invites them to press the ignition button.


    The commander and political commissar did not expect Chen Xinhui to issue such an invitation. They could not help but look at each other for a moment. Then they quickly declined and said, "this is the first fusion reactor that can be successfully ignited in human history. This honor should be attributed to Comrade Chen Xin. We will not seize this honor."


    Hearing what the political commissar said, Chen Xin thought for a moment and said to them, "what is this? It''s just pressing a button, or stone scissors and paper?"


    "Forget it, Comrade Chen Xin. Just press it yourself." The stone scissors and cloth are too playful. The commander and political commissar don''t mean to play around with Chen Xin.


    When Chen Xin heard them say this, he could only shrug his shoulders and sigh: "you two are too boring and lack of sense of humor. At this time, the stone scissors decide who presses the button to ignite the fire. When you mention it later, it''s also an anecdote in the scientific community!"With that, Chen Xin put his thumb on the bright red button on the console, and then pressed it hard.


    And with Chen Xin''s this, the whole micro reactor also came out a bigger roar, as if something was whistling.


    The political commissar and commander behind Chen Xin are nervous. They can''t help but hold their hands tightly and tighten their bodies. They are ready to take Chen Xin to a safe place and rush to shut down the reactor in case of problems.


    However, the quality of the reactor produced by the system is very reliable, there is no accident, and the operation is very smooth.


    "The sound is so sweet, it''s like a kitten snoring!" Listening to the buzzing of reactor operation, Chen Xin finally showed a smile on his face.


    The monitoring screen shows that the reactor temperature has reached 15 million degrees Celsius, and it is still rising, and the reactor pressure is also rising.


    Behind Chen Xin, the commander and political commissar look at the data displayed on the monitoring screen with a sense of panic. The data is really terrifying.


    "Don''t worry, thermonuclear fusion is like this. Only high temperature and high pressure can realize self-sustaining fusion reaction. The temperature of the reactor that human beings have ordered or succeeded in before can reach hundreds of millions of degrees. This is nothing at present." Chen Xin noticed their nervousness, gave them a smile, and then said, "connect the circuit. This thing is generating electricity. We can''t waste it."

 Chapter 393

    If the energy released by the fusion reactor is used for power generation, even the micro reactor in front of Chen Xin is enough to supply the whole Linshi city today.


    Although there is an ongoing heating network plan in Linshi to provide electricity and heating, there is no lack of energy at all, but before the complete completion of the heating network, especially the construction of the energy tower as the core, the heat and electricity that the whole heating network can provide is still limited.


    Therefore, it is also a proper intention to connect the micro reactor that has been in operation to the power grid in the city, so as to avoid the waste of power generated by the reactor.


    In addition, it can also test the stability of the reactor during operation and check whether there are any problems, which can be said to be a good thing.


    However, after the successful ignition and smooth operation of the reactor, the importance of the market has obviously changed dramatically.


    In less than 24 hours after Chen Xin reported to the scientific research department that the nuclear fusion reactor had been successfully ignited, several zhi-20 helicopters arrived in Linshi, escorted by two Wu zhi-10 helicopters, and sent more than 10 experts in nuclear physics.


    Many of them were already grey haired, but after the plane landed, they jumped out of the cabin without even waiting for the plane to stop. After they found out where the reactor was, they rushed to the room where Chen Xin installed the reactor.


    If the soldiers in charge of security at the gate did not stop them, these excited old people would rush in directly.


    Even so, after a safety inspection according to the process, these experts were able to enter the room in the shortest time and see the micro reactor in operation.


    Seeing the arrival of these experts, Chen Xin took the initiative to hand over the place to them, and also handed over the already prepared reactor design drawings to them.


    Chen Xin doesn''t intend to interfere in the research work of the reactor. The reason why he built such a micro reactor is just to verify his idea. Now that the technology and idea have been verified, the nuclear fusion reactor that he really wants to build will follow.


    As for the current micro reactor, it has perfect technology and runs very smoothly. There is no place for Chen Xin to spend more energy on it.


    Whether these experts want to move it to another place for research, or transform it into a nuclear power plant, and then continue to study on the spot, or even turn off the engine and disassemble it into parts for reverse technology, or simply use it to build Gundam or hunter mecha.


    Chen Xin himself can also turn his attention back to the construction of the heating network. The reactor can be completely handled by the people of the state. Anyway, the state can''t treat him badly.


    In fact, it is true. The day after the scientists arrived by helicopter, a special train arrived at the renovated railway station in Linshi.


    This special train is temporarily added. It is loaded with not only the equipment, instruments and relevant staff needed by scientific research experts, but also an official who specially came to see Chen Xin.


    It''s not unusual for an official to come to Chen Xin. He has encountered such things several times before. After all, his importance is becoming more and more prominent now. It''s normal for an official to come to him.


    However, this time, this official obviously belongs to the category of senior official, because he is a national prefix Department official from the temporary capital of Chongqing.


    Although the official said that he came specially to find Chen Xin, he didn''t stay long. After a brief in-depth conversation with Chen Xin, he left.


    What Chen Xin was left with by this high-ranking official who came and went in a hurry was the number of academicians of the highest scientific research institute of Yanguo, as well as the whole package of salary promotion.


    There is no need to elaborate on the specific treatment. It''s just that the price that the official originally intended to persuade Chen Xin to go to Chongqing, the temporary capital, was to build a special base for Chen Xin in Chongqing, not a refuge, but a serious underground research base.


    There are not only the best living facilities, underground greenhouses, gardens and swimming pools, but also a whole special force guarding the door for him, as now. Even the official said clearly that Chen Xin can ask for any personal requirements, discuss the conditions within the scope of national laws, and even let the organization solve the problem of the object, which belongs to Chen Xin''s parents Fine.


    What''s more, Chen Xin can also make a list of his family and friends who he wants to take to Chongqing. They can all be taken away. The people in the country can still afford it.


    This kind of condition may be very attractive to other people, but it is not so attractive to Chen xinlai. After all, with the system in hand, what kind of living environment do you want?


    However, Chen Xin still has two problems to solve for the seemingly attractive organization to solve the problem of the target. How dare he put forward the condition of making his home uneasy.


    In addition, Chen Xin agreed to other issues raised by the senior official, such as further deepening cooperation with the state and building a research base for Chen Xin.


    In fact, it''s the same thing to ask Chen Xin to move to Chongqing and build a base for him, but on the premise that Chen Xin didn''t want to go to Chongqing, the base was built in the city where Chen Xin was.Chen Xin also took this opportunity to select the site of the base at his own door. His request is to build the scientific research base on his own shelter. In addition, the special force responsible for protecting him will also be stationed in the past.


    Originally, Chen Xin was not willing to accept such layers of protection, but on second thought, this would be tantamount to putting his family under layers of protection, and Chen Xin was naturally willing to agree to such conditions.


    After all, for anyone who is not too cold-blooded, it is very important for his family to have a safe environment.


    Especially in this end of life, Chen Xin no longer wants to encounter the same things as the people of AZU before.


    It used to be OK to live alone, but now that his parents live here, Chen Xin can''t beat a group of terrorists into a pile of meat in front of them. Does he have to use shovels and plastic bags to collect the corpses?


    But if you have a team of special forces to guard the gate and build your home into a military base, this kind of thing can be completely avoided.


    After all, no matter how stupid or hard headed the lawless elements are, they don''t dare to break into the military bases of the five hooligans.

 Chapter 394

    It''s true that there are no Han critics who break into the five major rogue military bases, but people can''t be generalized.


    It''s not strange for some people to do irrational things when they are extremely angry. After all, no one can generalize, and some people think they can kill tigers.


    Especially for AZU, whose brothers are all dead, if the burning anger can be used to burn water to generate electricity, his current power generation should not be worse than Chen Xin''s micro reactor.


    The experience of losing all his brothers and subordinates and being chased like a bereaved dog has already let his anger burn through his reason.


    AZU is still alive indeed. After making such a big deal at the beginning, he escaped the pursuit of the police and survived successfully.


    After all, in this kind of environment, the snow in the wild is too thick and the visibility is low. It''s very difficult to chase. In addition, the brother who escaped with AZU fought hard to stop the pursuers and bought him time to escape with his life. It''s not impossible for him to escape.


    However, it has to be said that AZU, who was able to make a career, was really outstanding. In the process of escaping from the urban area, he actually relied on human resources to cross the dozens of miles of mountain road between the urban area and Linshi, and escaped to Linshi.


    You know, it''s a long night with extremely low visibility. Without a map as a guide and no other preparation, it''s like walking through the snow mountain to death.


    Even if the temperature was not as low as it is now when AZU fled, it would be a near death for him to hike through the mountain road for tens of miles and climb the mountain which has become a snow mountain.


    And even if AZU successfully climbed over the snow mountain and escaped from the urban area to Linshi, he also paid a very painful price, even nearly died.


    When he came to Linshi after walking dozens of miles of mountain road with the support of his will, his whole body was severely frostbitten, and his toes and fingers were badly necrotic.


    If it wasn''t for the medical institutions in the city that didn''t have problems at that time to treat him, amputate his necrotic seven toes and four fingers, and lie in the hospital for more than half a month, he might even have been difficult to survive.


    If it was before the disaster, AZU certainly would not have any chance or possibility to escape. After all, in the Internet age, not to mention the Skynet system composed of cameras all over the streets, only the wanted notices issued by the whole country are enough to make him escape.


    However, due to the impact of various disasters, the communication between different places has been greatly hindered. Even from the urban area to the neighboring city, the communication can not be as smooth as before.


    In addition to the frostbite that AZU suffered in the process of crossing the snow mountain, he lay in the hospital for more than half a month and grew a beard. His whole life has changed a lot. People who are not familiar with him may not recognize him.


    This also made a hole for AZU to settle down in Linshi.


    Because he was originally a local, AZU disguised himself as an ordinary survivor. He even got a job and went to work every day. It seemed that he was ready to live in peace.


    However, in fact, AZU''s heart is full of hatred and anger. He is always thinking about how to take revenge.


    But he lost all his brothers and men, and his body was greatly damaged because he walked through dozens of kilometers of snow. He had no capital to revenge, and he had no chance to revenge, which made him quiet and stable.


    After all, what AZU can have now is only his own rotten life.


    There is nothing he can do now. Even if he wants revenge, he can kill one or two people with his own life.


    If you only hurt one or two people, for AZU, it can''t be called revenge.


    In AZU''s view, only by making more people feel pain and burying them with enough human lives can they sacrifice their dead brothers.


    So AZU has been patient, waiting for an opportunity he thinks is appropriate, an opportunity for revenge.


    Originally, AZU felt that he might have no hope of revenge in this life, especially after the blizzard hit, the whole city fell into a dilemma. Under the double attack of disease and hunger, he even felt that he might die of disease or starvation.


    However, the arrival of Chen Xin and the rescue team not only brought hope to Linshi, but also let AZU see the hope of revenge.


    Destroy the rescue station set up by the rescue team, there should be a lot of people die, right? In this way, the city will die!


    If you can use a city to bury your brother, AZU thinks it seems acceptable.


    But before he had time to think about how to destroy the rescue station, the special police who followed the rescue team made him realize the gap.


    The gap between criminals with only a knife and SWAT armed with exoskeletons can not be overcome by will or hatred.And AZU found a more suitable target than destroying the ambulance station, that is Chen Xin.


    No need to deliberately observe, AZU can also judge that Chen Xin is an important person in the rescue team. If you kill him, it will definitely have a huge impact on the rescue team.


    Although it will not directly destroy the rescue team and rescue station, it is not a feasible way to let Chen Xin have an accident and affect the whole rescue team.


    So by pretending to be grateful to the rescued and talking to the special police of the rescue team, AZU finally got the information about Chen Xin, which made him more determined to kill Chen Xin.


    Not to mention anything else, after learning that his brothers were beaten into beehives in Chen Xin''s house, AZU firmly believed that he must kill Chen Xin.


    If this revenge is not avenged, what face does he have to go to see his dead brother?


    However, it is not easy to kill Chen Xin.


    AZU observed for a long time, but he couldn''t find a chance to kill Chen Xin. After all, Chen Xin was wearing power armor almost all the time. When Chen Xin took off his power armor and went to sleep, he was in an armored RV, so he had to wait for the opportunity.


    Just when AZU was waiting for the opportunity, the special forces who came to protect Chen Xin finally arrived. Facing the heavily guarded military camp, AZU almost fell into despair.


    A heavily guarded military camp, even if it is garrisoned by the worst army in the world, is not something he has the ability to break.


    No matter how much he wants revenge, he won''t really rush to a military camp. Moreover, he also finds that Chen Xin doesn''t stay in the military camp all the time. He still has a chance.

 Chapter 395

    Of course, Chen Xin didn''t stay in the military camp all day. He had said before that he would still go to the camp in the morning to deal with the construction of the heating network.


    This is the only chance for AZU to get close to him. As for Chen Xin''s sleeping time in the camp at night, AZU doesn''t think he has a chance.


    Although Chen Xin is also in the camp, the workers are busy in the camp during the day. It''s not obvious and strange for someone to walk around the camp. But at night when everyone is sleeping, it''s very obvious for someone to walk around.


    So AZU decided to find a chance to get close to Chen Xin in the daytime, and then he tried to kill Chen Xin and avenge his dead brother.


    But if you want to do this, AZU has to find a way to sneak into the camp first, or you can''t even enter the gate to kill and set fire. That''s a fart!


    Fortunately, the opportunity soon appeared. Because of the expansion of the construction team of the heating hub in Linshi, AZU took the initiative to sign up and became a member of the construction team.


    Although he has become a member of the construction team and theoretically has the opportunity to go to the camp to get close to Chen Xin, or wait for Chen Xin to appear at the construction site, it is still very difficult for AZU to really wait for the opportunity to get close to Chen Xin.


    After all, not all construction teams will go to Chen Xin''s camp. They are scattered in various construction sites. Only the main personnel in charge of construction will occasionally go to the camp to report the construction progress and related problems.


    Chen Xin himself does not go to the construction site every day. If he wants to wait for him to show up, he has to take a chance.


    So if AZU wants to get close to Chen Xin, he has to be the main member of a construction team to go to the camp and meet Chen Xin.


    This is not difficult to achieve. After all, although there are only a dozen people in a construction team, in addition to the person in charge of each construction site, there are always one or two leaders among the workers.


    As long as AZU becomes the leader and has a good relationship with the person in charge, he will naturally have the opportunity to approach Chen Xin.


    A little bit of small means, let the person in charge for a while, AZU can replace the person in charge to report to the camp.


    Come to the camp, AZU restrain his excited mood, let himself look nothing unusual, carefully searching for the figure of Chen Xin.


    But AZU was not careful. After entering the camp, he saw Wang Hai and his fighting team.


    In the past, AZU didn''t have the courage to touch Wang Hai, but now he has no weapons and no men, and he is half disabled. If he wants to meet the elite special forces, it''s just an egg against a stone.


    And once the identity is found, it is impossible to kill Chen Xin.


    So AZU must be very careful to make everything right.


    Fortunately, before long, Chen Xin appeared in the camp, which made AZU''s heart beat faster.


    What surprised AZU was that Chen Xin was accompanied by a woman with an intimate look, which made him pick his eyebrows.


    While insinuating that Chen Xin didn''t forget her woman when she was dying, she followed others into the meeting room with no expression on her face.


    They are here to report their work. No matter how much AZU wants to kill Chen Xin, he can''t do it in full view of the public. In that way, he can''t even change the limit.


    Therefore, we must wait for the opportunity to create an opportunity to be alone with Chen Xin in the room. Only in this way can we have the opportunity to kill him and give ourselves enough time to escape.


    But now it seems that AZU thinks he may have to kill one more person.


    The process of the meeting was very good. The person in charge of each construction site reported the progress of the work, and said some areas that needed coordination and cooperation. The meeting was over.


    Since you need to disguise yourself, AZU naturally is the same. He seems to report his work to Chen Xin seriously.


    After the meeting, everyone left the meeting room one after another. AZU pretended to have something to say and left the meeting room a few steps later.


    When Chen Xin and the woman around him were about to leave, he rushed up to Chen Xin and said, "Mr. Chen, can you spare me a little time? I want to ask you something. "


    Hearing AZU''s voice, Chen Xin picked his eyebrows, but he didn''t refuse. He just said to the woman beside him, "ah LAN, go outside and wait for me first. I''ll find you later."


    Then he asked AZU, "what''s the matter with you?"


    "Well, we encountered some problems in the construction, and the person in charge asked me to come to you for advice." As AZU spoke, he approached Chen Xin. He was not armed, but he was confident that he could kill Chen Xin with one hand: "you are the designer of the heating hub. We can only consult you about this."


    "Oh? What''s the problem? " Chen Xin did not doubt that there was him, let AZU explain at the same time, he also sat down again: "is the problem encountered in the construction?"


    "Yes, we met..." AZU saw that Qin LAN had gone out and closed the door. Then he got close to Chen Xin and suddenly put out his hands and pinched him by the neck: "go to die!"Chen Xin didn''t expect to encounter this kind of situation. For a moment, he didn''t react as well. He was grabbed by AZU''s throat. He reached out to resist, but he couldn''t breathe at all. He couldn''t break AZU''s forceps like hands. Even the cry for help was suppressed in his throat.


    Seeing the hopeless struggle, he even began to blacken, and his body was pressed on the chair. Suddenly, Chen Xin reached out to the table, pushed it hard, and made a loud noise.


    At this time, AZU completely indulges in the pleasure of revenge, and does not care about Chen Xin''s action. He just pinches Chen Xin''s neck with a ferocious face and wants to strangle him alive.


    However, at this time, Qin LAN, who had already gone out, came back again. When she opened the door, she saw that a Zu was pinching Chen Xin''s neck. She was shocked. The whole person rushed over, grabbed a Zu, pulled him back, and hit him on the head.


    Being pulled by Qin LAN, AZU doesn''t want to let Chen Xin go, but the power of Qin Lan''s right hand is irresistible to him. In an instant, the whole person is pulled to a stagger, and then he is hit by Qin Lan''s fist.


    This is beyond AZU''s expectation, but he is also a mercenary who has been through a lot of battles. He wants to conquer Qin LAN and then kill Chen Xin, but he doesn''t expect that he has not recovered from Qin Lan''s fist before, and Qin Lan''s second fist hits his head like a hammer.


    Boom! AZU felt that his head was really hit by a hammer, and he was immediately blinded, and then he lost consciousness.

 Chapter 396

    When Wang Hai hears Chen Xin''s cry and rushes into the meeting room, what he sees are Chen Xin, who is sitting on the chair rubbing his neck, Qin LAN, who squats beside him and is anxiously examining him, and AZU, whose half face on the ground is smashed with blood and swelling like a pig''s head.


    "What''s going on?" Wang Hai quickly let his soldiers control AZU on the ground. At the same time, he asked people to call the medical soldiers in the team. He came to Chen Xin and asked him.


    "I don''t know. He''s a worker who came to report his work today. After the meeting just now, he told me that he had a problem to ask for advice, but he suddenly rushed up and grabbed my neck. If Alain hadn''t rushed in and subdued him, I would have been strangled by him." Chen Xin rubbed his neck and explained to Wang Hai intermittently. Just now, he really thought he was going to die.


    "Don''t tell me, where''s the doctor? Call the doctor quickly to check ah Xin! " One side of Qin LAN stopped Chen Xin to continue to say, shouting at Wang Hai.


    Wang Hai is also in a cold sweat. Under his 24-hour protection, some people can touch Chen Xin and assassinate him. This really makes Wang Hai''s scalp feel numb.


    If it wasn''t for the fact that no dangerous goods were allowed to be carried into the camp, the killer would have to pinch his hands to delay his time, I''m afraid Chen Xin would be dead now.


    For Wang Hai, this is not only a blot of mission failure, but also a great shame!


    As the most elite special forces of Yan state, he was ordered to protect an important person, but the protected person was almost killed. Whether the reason was Wang Hai or not, it was his responsibility not to protect him.


    If Chen Xinzhen is successfully assassinated, their whole army will be shamed. In that situation, Wang Hai feels that he is still happy.


    Of course, before that, he would catch all the people who assassinated Chen Xin and drown them in the toilet!


    But now is not the time to blame himself. While Wang Hai asks the soldiers to detain the controlled AZU for interrogation and ask him if he has any accomplices, he also asks his combat team to enter a fighting state and protect Chen Xin more closely. At the same time, he is also contacting the military camp to send reinforcements.


    Their whole army was sent to protect Chen Xin. Now that something has happened to Chen Xin, it is obviously impossible for Wang Hai to protect him.


    When Qin LAN urges Wang Hai to call a doctor, the medical soldiers rush over from the outside. After an examination, they confirm that Chen Xin is not seriously ill, but his neck is still injured. It''s better to go to the hospital for a professional examination and be treated by a professional doctor.


    Hearing what the medical soldiers said, neither Wang Hai nor Qin LAN had a second word, so they immediately prepared to send Chen Xin to the hospital for treatment.


    However, Wang Hai did not immediately let Chen Xin leave the room. Instead, after the support from the military camp was in place, he let several soldiers escort Chen Xin and send him to the armored car driven out of the military camp.


    At this time, around the armored vehicles, the special forces ordered to protect Chen Xin simply poured out. Several armored vehicles and all terrain vehicles carrying soldiers and light and heavy weapons surrounded Chen Xin''s armored vehicles to provide protection.


    At the same time, several combat teams were scattered to search and clean the surrounding buildings and any suspicious places to avoid other potential dangerous elements.


    As for the other side of the camp, all the people have been controlled by these special forces and are under centralized guard, waiting for the follow-up investigation.


    When Chen Xin was assassinated, although these people may be irrelevant, they are all suspected. At this time, we can only catch 1000 people by mistake, and we can''t let one go.


    The military camp was originally to escort scientific research experts, but the two Wuzhishi helicopters that had not yet left also took off at the request of the commander of the special forces, hovering over Chen Xin''s armored vehicle, providing detection and firepower cover.


    Such a big battle obviously scared everyone who saw such a big scene, and the municipal government was also shocked by this incident.


    The senior officials who had come to talk with Chen Xin had just said hello to Linshi municipal government before they left, asking them to take good care of Chen Xin. Now Chen Xin was assassinated, which really made them sweat.


    What''s more, the big battle of the special forces is really frightening. When they watched the whole convoy come down from the helicopter to a hospital with the best conditions in Lincheng, they thought that Chen Xin, an important person, was dying and probably could not be rescued.


    After all, Linshi is only a small city with limited medical level and conditions.


    However, when Chen Xin got off the armored car with Qin Lan''s help, people from the municipal government and the hospital were relieved.


    No big problem is the best news. As for the follow-up investigation of responsibility and the handling of related problems, it can be put in the future. As long as Chen Xin is OK, the responsibility of relevant personnel will undoubtedly be much lighter.


    Although these words are utilitarian, Chen Xin''s dead and undead are two completely different concepts. Undead need to be rescued and undead need not be rescued are also two different situations.


    Even if Chen Xin needed to be rescued, he failed to rescue or successfully rescued in the rescue process, which would lead to completely different results.Now Chen Xin does not need too much treatment, but needs comprehensive and meticulous examination and recuperation, which is the most ideal situation for many people.


    A group of people surrounded Chen Xin and sent him for examination and treatment. This time, the commander directly sent two fully armed combat teams around Chen Xin, and directly asked two soldiers to protect him for 24 hours. Chen Xin was not allowed to leave their sight for a second.


    Under such strict protection, Chen Xin finally completed all kinds of examinations and confirmed that there was no serious problem. Only after the soft tissue contusion in the neck, he was sent to the best ward of the hospital for further hospitalization.


    Although Chen Xin doesn''t feel that he needs to be hospitalized, at the moment, everyone dares not to let him mess around any more. Qin LAN is very determined to press him directly to the hospital bed, and to handcuff Chen Xin''s handcuffs to the hospital bed.


    In the face of Qin Lan''s radical approach, Chen Xin has no choice but to let it go.


    After all, for Chen Xin, he almost died before, which was a great shock to him.


    Lying in the hospital bed, he couldn''t help but reflect on whether he was too careless and didn''t care about his own safety.


    Maybe I should consider improving my personal combat effectiveness and protection level?


    Chen Xin seriously thought about this problem, but without waiting for him to figure out a way of thinking, a burst of tiredness gushed out, which made him close his eyes and fall asleep on the bed.

 Chapter 397

    After Chen Xin was assassinated, the news of his assassination was reported to their respective superior departments by the commanders and scientific researchers of the municipal government and special forces through different channels.


    The impact of this incident is far beyond Chen Xin''s own expectations, even because he has just accepted the status of academician of the highest Academy of Sciences of the state of Yan. This incident also shocked the highest leadership of the state of Yan.


    Under such circumstances, no one dare to let him stay in Linshi.


    Both the municipal government and the commander of the special forces were ordered to send Chen Xin to a safe place.


    So after a few days of training and confirming that Chen Xin is OK, the commanders of the municipal government and the special forces plan to send him to a place safe enough to have people watch over him 24 hours to avoid such an accident.


    Chen Xin himself has no objection to this. After all, he was assassinated and almost lost his life. Now he just wants to go back to his refuge and build it into an iron wall that no one can enter to protect his safety.


    As for Chen Xin''s idea, the commander of the special forces naturally gave great support. He not only sent two-thirds of the soldiers to escort Chen Xin home, but also assigned all the heavy weapons to these soldiers to ensure Chen Xin''s safety on the road.


    And Linshi side became alarmed.


    All the shelters were searched jointly by the soldiers of special forces and the police. After a close search, some people were found to have problems and taken away by the police.


    As for the people related to this matter, they have been strictly examined and cross examined, and the responsible persons have also been investigated one by one.


    After all, AZU was involved in the construction team before, which led to a thorough review of the whole construction team.


    The construction team that AZU had been in before was replaced directly by everyone, and a construction team was reorganized to take over.


    Naturally, the progress of construction has been affected. After all, the construction team is under review, and the project will be suspended naturally. Even if there is no problem, the workers will not help but become panic and uneasy.


    Fortunately, after a period of review, no one was found to have any problems. Only a few of the workers had some petty theft. After these workers were transferred, the municipal government organized a group of people to appease them, so that the project could continue.


    But as the project goes on, Chen Xin can no longer be in charge of it, but someone has to be responsible for it. After some discussion, the head of heating network engineering falls to Professor Zhang.


    One is that the old professor himself is a geologist. In addition, he has participated in the construction of the heating hub before. He has at least an understanding of the problems encountered in the construction process of the project. As the general director, it is most appropriate to make overall planning.


    Second, Chen Xin strongly recommends that, after all, in the construction of the heating hub before, only Professor Zhang and Cao Daren were familiar with all matters and were able to take charge of the overall situation. Compared with Cao Daren, who is now the general leader of the construction team, Chen Xin believes more in Professor Zhang''s ability.


    Cao Daren''s hesitation about the arrival of the oil drilling team eventually made Chen Xin feel that he was a little short-sighted, while Professor Zhang, an older generation, would not at least put his personal interests before the national interests in the matter of national construction.


    In addition to the heating network, Chen Xin''s micro nuclear reactor in the military camp was handled by scientific research experts who came to study it. However, Chen Xin only used a small part of the nuclear raw materials before, but he had to go with him.


    Chen Xin himself has the right to dispose of this kind of thing and stay in the military camp. Other people have no authority to dispose of weapons grade nuclear materials.


    As for the two induction furnaces he made, they were also left to the researchers for disposal.


    For Chen Xin, although these two induction furnaces are easy to use, they are not necessary to be taken away. On the one hand, Chen Xin can redo them at any time, and on the other hand, the heat of the induction furnace is amazing.


    It''s OK to put it outside the city. If you take it back, put it in the shelter. Chen Xin doesn''t think he has a place to cool it.


    So it''s better to leave it to the researchers to dismantle the research. Maybe they can reverse some powerful technologies.


    As for Chen Xin''s own use, is it better to go back and build a new and better molecular metallurgy furnace?


    After all, Chen Xin, Qin LAN and Mo Qingyan, escorted by a large number of special forces, went through the snow between the city and the city and returned to his refuge.


    Just before going home, Chen Xin deliberately tells Qin LAN and Mo Qingyan, and Han Ping, who is so remorseful for not protecting Chen Xin before, that he doesn''t allow them to tell his parents about his assassination.


    For Chen Xin''s request, Qin LAN and Mo Qingyan look at each other and agree. After all, Chen Xin''s parents are old. If they know that Chen Xin was assassinated, they will be worried.Since Chen Xin is no longer in serious trouble, he has come back to his own shelter obediently, and there are a large number of special forces guarding outside. If safety is not a problem, Qin LAN and Mo Qingyan are not the talkative women who like to complain.


    However, Han Ping blamed himself for not protecting Chen Xin as a bodyguard. At this time, facing Chen Xin''s request, he put forward an exchange condition.


    "Mr. Chen, you brought our brother to Hunan Province to make a good life for us. You are the great benefactor of our two brothers. Originally, I should have listened to you, but the previous events were too dangerous. I hope I can follow you in the future, lest similar things happen again and I can''t protect you." Han Ping doesn''t really want to tell his parents about Chen Xin''s assassination. He just wants to put forward that he should pay more attention to protecting Chen Xin in the future.


    For Han Ping''s request, Chen Xin thought about it or nodded and agreed to Han Ping''s request.


    Although Han Ping used to be an auto soldier, his ability is mainly to drive as a driver. As a bodyguard, his skill is only better than Qin LAN before he was injured. Now he can''t stop Qin LAN who has power boxing.


    However, Han Ping is very down-to-earth. During this trip to the city, Chen Xin told him that everything had been done very well, which made Chen Xin have more trust in him.


    In addition, Han Ping is a man, and many things Qin LAN is not convenient to do are more suitable for Han Ping to do.


    Therefore, although there will be special forces following Chen Xin 24 hours later, Chen Xin still agrees to Han Ping''s request and lets him continue to follow him in the future.


    After dealing with these things, Chen Xin goes home with Qin LAN and Mo Qingyan.

 Chapter 398

    Back at home, where he had been away for more than a month, Chen Xin could not help feeling a lot.


    Although Qin LAN and Mo Qingyan did not tell his parents about his assassination according to his request, they came home after more than a month, which inevitably attracted their parents'' concern and nagging.


    If it was in the past, Chen Xin might not care much, and even find his parents'' nagging a little annoying.


    But in the end of the day after this disaster, this nagging and concern is precious.


    However, many things settle down after Chen Xin goes home, and Chen Xin also needs to make an inventory of the things on hand.


    After all, now that he has accepted the title of academician of the highest Academy of Sciences granted by the state, his cooperation and ties with the state have become closer, and many things have become different.


    First of all, it is natural that the treatment he negotiated with the senior officials from Chongqing, and the most important one is to build a scientific research base for Chen Xin.


    The site of the research base was put in front of Chen Xin''s home and merged with the special forces barracks that came to protect him.


    On the one hand, Chen Xin does this for convenience. At least he doesn''t have to run around when he goes out to work, and he doesn''t have to be away from home for a long time. In addition, there are special forces stationed at his own door. Naturally, there are no more security problems.


    On the other hand, it is natural to upgrade the scientific research base and barracks with the help of the system.


    In this way, we can not only upgrade the three as a whole, but also integrate them into a whole. It is convenient for Chen Xin to use.


    After going through a series of things in the city, Chen Xin also has some new ideas for his home and wants to implement them. Now he has to build a scientific research base and a military camp at his home, which is just convenient for him to realize these ideas one by one.


    According to Chen Xin''s idea, the military barracks and scientific research bases should be placed on the ground, while the underground is his own refuge. The three should form a whole, rather than simply placing the general barracks and scientific research bases at his door.


    After all, Chen Xin is not good at real scientific research. All he has is to use the system to make all kinds of black technology equipment.


    Therefore, under such circumstances, it is impossible for Chen Xin to engage in scientific research, and the scientific research base is not really used for his research.


    In fact, the upper level departments also clearly know that the role of this scientific research base in Chen''s novice is not as good as that of a machining workshop, but they still gave it.


    Because Chen Xin is not the only one in a scientific research base.


    Previously, Chen Xin cooperated with the state to help the state upgrade its research projects. Such cooperation can not be said to be inefficient or bad, but for the state, it is actually a waste.


    Because all kinds of scientific research projects leave Chen Xin, other researchers can also produce results, but compared with Chen Xin, it''s much slower to produce results after one pass, and it takes more resources and time.


    Although the state realized Chen Xin''s value before and accelerated various scientific and technological processes through cooperation with him, which really brought great benefits to the state, after Chen Xin manufactured the micro nuclear reactor, the senior management obviously realized that Chen Xin''s usage was not like this.


    Using existing scientific research projects to upgrade Chen Xin is certainly a way to accelerate the progress of science and technology and make it develop rapidly, but it also limits Chen Xin''s play.


    This time, the micro reactor and the heating network made the senior management realize that it is better to let Chen Xin play freely than to let him follow the existing path.


    After all, the distance between the large Tokamak device that is still under research and the micro fusion reactor on Chen Xinsheng''s is unreasonable. If we follow the normal development of science and technology, we can''t say that we can achieve what Chen Xin can do in a hundred years, but at least in a few decades.


    So this time, what the top management wants to do is to give Chen Xin enough manpower to build a scientific research base to play his own role. Chen Xin is only responsible for turning his ideas into reality, leaving the rest to these researchers.


    For Chen Xin, he is also happy to see such a change in the way of cooperation.


    Through this trip to the city, Chen Xin also realized that although he has a system and can play a role in many things, his role in many cases is limited, and even affects others because of himself.


    Just like this time he was assassinated, because he stirred up the whole city, almost everything was delayed.


    This is obviously not a good thing, or even a very bad situation.


    It is the instruction of our ancestors since ancient times that the son of a thousand gold does not sit down. Although this is not necessarily true, it does have its truth.


    Just like Chen Xin, nowadays, even if he is injured a little bit, many people will be shocked. Many big people who Chen Xin could not touch before come back to ask for help. However, if something really happened to him, some people will be involved in it.


    And these are only the second. With the influence of Chen Xin''s ability, if anything happens to him, it will be a huge loss for the whole country.Under such circumstances, the high-level officials of Yanguo certainly hope to find a safe place to offer Chen Xin like the most precious porcelain, so as to avoid bumping.


    Although Chen Xin had not been assassinated when the state sent someone to talk to him about the incident, Chen Xin had been in the city for more than a month before, and more than one or two scientific research projects were delayed.


    Compared with the losses caused by these delayed projects, it is not worth mentioning to build a special scientific research base for Chen Xin, and Chen Xin himself deserves such investment from the state.


    Now that things like assassination have happened, Chen Xin''s safety has naturally become more important.


    Although there is a whole special force at the door, which looks like it has been raised in captivity, for Chen Xin, this is not protection?


    And to be honest, these special forces only come to protect Chen Xin''s safety, and will not restrict his personal freedom. If Chen Xin really wants to go out, these special forces can only follow him, and they can''t have any restrictions on him.


    Therefore, upgrading the scientific research base together with the military camp and his own refuge is the next thing for Chen xinlai.


    As for such a large-scale upgrade, are there enough upgrade points for Chen novices?


    Since he went to Linshi before, Chen Xin has not paid attention to his total number of survival points for some time. After all, since the production line of isotope thermoelectric battery started to run, one hundred isotope batteries per day, with an average of three to five batteries, can bring 5000 survival points directly to Chen Xin''s account. Chen Xin''s total number of survival points has already exceeded six figures.


    Unless there is a change in the first digit, there is no need to look at the increasing number every day.

 Chapter 399

    Chen Xin is not surprised that his survival has exceeded six figures, and even thinks that it seems a little less.


    This is the benefit of cooperation with the state. Chen Xin can also get survival if he helps others indirectly. Therefore, by improving the living conditions of others on a large scale, the state can naturally bring him a large number of survival.


    In fact, if the production of isotope batteries had not increased, Chen Xin would have gained more survival points.


    So this is the reason why Chen Xin is less and less concerned about the growth of his own survival points, because there is really no need to pay much attention to it. As long as he confirms that he will not spend it all at once, a large number of survival points will be recorded again in a few days.


    With a large number of survival points, Chen Xin has enough confidence and strength to do what he wants to do. He doesn''t have to worry about survival points any more.


    If Chen Xin didn''t choose to cooperate with the country at the beginning, but only slowly saved his own survival points, he might have saved a year, which may not be as much as the current day.


    After all, the survival base that a country can provide is too large. Even if there is a single acquisition limit, as long as the number goes up, the total amount will naturally go up.


    As for the fact that there are only private refuges, no matter how they develop, the speed of development can not be compared with that of a country.


    Chen Xin once thought carefully that maybe this is the real usage of the doomsday survival system he obtained.


    After all, before disaster and doomsday, personal heroism is meaningless. Only when we unite and gather the strength of all people together, can we do more things and let more people live, rather than just a few people, even the continuation of civilization and population.


    Chen Xin doesn''t want to be the hero in the early stage, and he doesn''t think he can lead other people. It''s good for him to be an assistant of exporting black technology like this.


    Just like when playing RPG at the beginning, Chen Xin preferred to play the role of assistance and treatment in the team rather than the role of output or tank, and he didn''t want to be the team commander, although his command ability was not bad.


    Although Chen Xin doesn''t want to be a leader now, when a large group of people around him, he is naturally placed in the position of leader, which makes him have to think about the next way.


    According to Chen Xin''s idea, he is planning to build an ecological dome in this part of his home.


    This is not a whimsical idea, nor is it something that can be realized even if we have a system.


    When many people hear about the ecological dome, the first thing they think of is the kind of protective cover that covers the whole city in science fiction. They think it''s a very black technology.


    But in fact, the ecological dome has been mentioned before, and human beings have built similar existence long ago.


    The famous Biosphere 2 experiment is actually an ecological dome, but it is not built into a spherical dome, but a square stepped pyramid structure.


    The whole project was built in the 1980s. At that time, technology was not as advanced as it is now, so its structure could not really build a large spherical dome.


    Limited by various technical problems at that time, the Biosphere 2 experiment finally failed, unable to achieve internal circulation and independent of external materials.


    However, with the development of science and technology, the technology of large-span spatial structure has become more and more mature, and the internal space of related buildings is also more and more broad. It is not a problem to build a small ecological dome.


    As for the ecological cycle inside the ecological dome, if we really want to build an ecological circle completely isolated from the outside world, on the premise that Chen Xin does not use the system upgrade, it is certainly not enough.


    But it''s not easy to build an environment similar to a plant greenhouse.


    After all, the most important air and water can be imported from the outside, so it is not difficult to maintain the operation of the whole ecological dome under such a premise.


    According to Chen Xin''s design, the plan is to build a large dome on the ground with a span of about 500 meters, covering the area in front of the mountain where his refuge is located.


    Then raise the temperature of this area, and build scientific research buildings and military barracks in this area.


    Although the construction of a large dome with a span of about 500 meters is very difficult, it is not impossible to complete with Yanguo''s infrastructure capacity. After all, it is not impossible for large airports, stations and gymnasiums to have a larger space span.


    In addition, Chen Xin does not plan to build a hemisphere to buckle on the ground, but only plans to build a flat arc dome. The construction technology is not as difficult as he thought. Even if there is no support column inside, it can be built.


    When there is a relatively closed environment, as long as the building materials are enough thermal insulation, and there are enough heating facilities inside, it is easy to create a warm enough greenhouse environment.


    As for scientific research bases and military barracks, when the dome is built, all the buildings can be completed by the way.With the suitable temperature in the greenhouse environment and the stable supply of fresh water, it is not difficult to plant and build a small ecosystem.


    Even if a small ecological dome has all the elements, there are too many things involved in how to make the ecosystem self cycle, which is not what Chen Xin can do.


    But fortunately, he has a system, and any problems will be solved as soon as he upgrades.


    Even if there is no need to upgrade the system, it is still possible for the state to send two biologists to help build an ecosystem with stable circulation.


    For Chen Xin, of course, he won''t use the sharp weapon of system upgrade, and he won''t say that he is working hard alone.


    At that time, let the state send biologists to build the ecological system, and then upgrade and optimize the system by themselves. In this way, we can create a comfortable ecological dome and recreate the scene of the past under the snow and darkness!


    Of course, such an ecological dome is not for enjoyment. Although it is a kind of enjoyment to live in such a warm and comfortable ecological dome with green ecological environment in the present environment, the establishment of the ecological dome is also of great scientific significance.


    The large-span spatial structure can be used not only to build ecological dome, but also for large-scale planting greenhouse. The small-scale ecological cycle can not only create a comfortable green ecological environment, but also help to study circular ecological agriculture.


    It can be said that the technology of building ecological dome can be used to build planting greenhouse.

 Chapter 400

    "Ah LAN, long Niang, do you think there''s anything to be changed in the shelter now?" In his own shelter, Chen Xin spread out a blueprint of the current shelter on the table and asked Qin LAN and Mo Qingyan who were sitting in the room.


    Now that he has decided to upgrade his refuge and the scientific research base to be built together with the military camp, Chen Xin has decided to ask everyone''s opinions to see how to adjust his refuge.


    With Chen Xin''s inquiry, the blueprint spread out on the table also projected a 3D stereo projection. The light blue lines formed the structure of the current refuge, and the text instructions were carefully attached.


    Looking at the projection of the shelter in front of him, Qin LAN asks Chen Xin curiously, "Xin, do you want to transform the shelter?"


    "Yes, I accepted the title of academician of the highest Academy of Sciences issued by the state and the corresponding treatment. One of them is to build a scientific research base for me. I plan to put this scientific research base on it and transform the refuge by the way." Chen Xin explained to Qin LAN and gave them a special look: "I used to live alone, and then the transformation was nothing more than adding a few more rooms and adjusting the structure, but now you still have your parents and Han Ping and their two brothers live here, so it''s better to transform them again."


    "That''s true, but there is a lot of work to be done in the reconstruction of the refuge. It''s a bit too much to do with the walls and the earth and stone excavation, isn''t it? Now that the shelter is very comfortable, I don''t think it''s necessary to make trouble. " Mo Qingyan shakes her head after hearing Chen Xin''s words. She doesn''t seem to support Chen Xin''s reconstruction of the refuge.


    It''s normal. After all, if you don''t use the system upgrade, from the perspective of normal people, if you want to reconstruct an already built underground shelter on a large scale, the construction volume is really large. In Mo Qingyan''s view, it''s unnecessary.


    Chen Xin could not deny this, but only nodded slightly, but still asked them: "I will solve the construction problems. Without considering the construction problems, do you think there is anything that can be improved in the shelter now?"


    Hearing Chen Xin''s question, Qin LAN and Mo Qingyan look at each other. Although they don''t understand why Chen Xin wants to transform the comfortable shelter that seems to be living now, they still don''t firmly oppose Chen Xin. After all, they just make a design drawing and put forward some ideas, which is nothing.


    So after they thought about it for a while, Qin LAN took the lead in saying: "I think it would be good if there was a fight training room. This time, ah Xin, you were assassinated. If you can accept some fight training and react, that person is not so easy to hold your neck."


    "Fight room? Can add, just can also be used to exercise at ordinary times Chen Xin thought about it and thought it was a good suggestion. After all, he had thought about building a place for physical exercise before, but later he forgot.


    As Chen Xin agreed, he pointed to the blueprint and adjusted it a few times. Next to the medical room on the first floor, he pulled out another room, which was very large.


    When Mo Qingyan saw that Chen Xin had made the space on the drawing so large, she thought he was just imagining it, so she said half jokingly, "in that case, I think we can draw a special farm. Now, although there is enough space to grow in the greenhouse, the chicks have grown a little bigger. If we want to raise chickens or other livestock later, we still need to have a bigger farm It''s a little bit of a place. "


    Mo Qingyan''s suggestion is also serious. The hens Chen Xin brought back and the chicks hatched from eggs are all raised in the planting greenhouse, but there is only a small area for these chickens to live in. The place is not big.


    As the chicks are growing up, the place has obviously become a bit crowded.


    If Chen Xin doesn''t want to confine the chickens in cages, like the way in the past when chickens were raised in cages from chicks to slaughtering, it''s necessary to make it bigger. At least, it''s necessary to make the place where the chickens can move as a farm.


    So after Mo Qingyan made a suggestion, Chen Xin also raised his hand and pulled out a space that could be used as a breeding farm beside the original greenhouse.


    And Chen Xin also conveniently adjusted the structure and location of the greenhouse and the height of the whole shelter, poking the top of the greenhouse out of the ground.


    "Well? Why poke the roof of the greenhouse out of the ground? " Qin LAN to Chen Xin such modification, immediately feel some don''t understand.


    The whole shelter was placed underground to avoid all kinds of natural disasters caused by the impact of meteorites. Naturally, the planting greenhouse was also wrapped in soil. However, with Chen Xin''s adjustment, the top of the planting greenhouse was exposed to the ground, which is really puzzling.


    "When I was near the city, I had observed that the sky would be slightly bright at noon when the light was the strongest." Chen Xin replied that it seems to have nothing to do with the exposure of the top of the greenhouse, but immediately added: "the dust in the sky is expected to gradually begin to fall within one year, and gradually return to the original light level in about three years.


    Although there is still a large amount of dust in the stratosphere, which affects the light intensity, generally speaking, after three years, the sky will be bright, and the light intensity can reach the light intensity that can appear in strong haze weather.In this light intensity, although the plant growth will be relatively slow, but with the light lamp can still grow crops normally. So I put the top of the planting greenhouse out of the ground, just for this, and then I can use the sunlight to provide light for the crops by installing transparent glass and light panels on the top of the planting greenhouse


    "I see. Are you going to use the light board to refract sunlight into the greenhouse?" Mo Qingyan suddenly understood Chen Xin''s idea.


    In fact, this method of refracting sunlight for lighting has been used since ancient times. Many high-rise buildings in modern buildings have adopted similar design. By installing refracting light panels on the external walls of buildings, the external sunlight can be refracted into the interior for lighting, so as to reduce the use of artificial lighting.


    "It''s a good design, but in that case, isn''t the shelter going to be transformed?" Qin LAN looks at the blueprint that is changed by Chen Xin in front of him and asks him something uncertain.


    Qin LAN did not ask, but if Chen Xin did, it would be too big to change the whole shelter.


    Chen Xin just nodded and added some other things to the blueprint. Then he said, "the state will pay for this transformation. Of course, we need to add back some designs that were abandoned for various reasons when we built the refuge."

 Chapter 401

    At the beginning, when Chen Xinhe''s group Friends of survival group designed the shelter, the most ideal solution proposed was to use missile silos or abandoned military air raid shelters to transform the shelter and build it into a small community.


    But the plan was abandoned because of China''s policy and economic problems, and everyone turned to build their own private shelters.


    In the initial idea, we actually had many ideas about the design of the shelter.


    Some of these ideas are very practical, such as planting greenhouse, water circulation system, air filtration and communication facilities, but some are unrealistic, but they can also play a role.


    For example, it''s a good idea to build a library and bring a large number of paper books into the shelter. After all, paper books can last longer than electronic products. When reading, as long as you cherish books, a book can be read for decades.


    Of course, this is a very practical idea, but it''s a pity that before the disaster, with the development of the Internet, people rarely read physical books. Even the bookstores that used to be all over the streets have disappeared for many years, and it''s very difficult to buy physical books.


    In addition, everyone brought electronic products into the shelter, so the library was not so necessary. So when Chen Xin built the shelter, he left out the library.


    When they first referred to the design of some foreign refuges, they saw other people''s refuges, such as cinemas, supermarkets and swimming pools. In fact, they had some ideas in mind.


    It''s just limited by the actual situation, because it''s not the community model originally envisaged, so the supermarket is useless directly, and the cinema can prepare its own home theater in the living room, which is just fine.


    As for the large area of the swimming pool, it also consumes precious water resources. If the weather is too cold, we have to prepare a constant temperature equipment for the swimming pool. It''s too luxurious and troublesome. It''s better to prepare a big bathtub. No one really builds a swimming pool.


    In addition, there are bars only owned by Mo Qingyan''s family, billiards rooms of some group friends who used to like playing billiards in the urban area, and VR experience rooms of group friends who used to play VR. These functional facilities belong to only one or two talents, which are also yearning but not available to others.


    Although Chen Xin later provided himself with functional facilities such as fish ponds and medical rooms through material exchange, he still did not have some things.


    Now, however, Chen Xin feels that he can build some facilities to improve his quality of life, so that he can lead a better life and a more comfortable life.


    For example, the frozen wine in Mo Qingyan''s cellar, Chen Xin was discussing with Mo Qingyan when to get the wine out.


    If he can get that batch of wine, Chen Xin thinks he can build a wine cellar and bar in the shelter.


    Moreover, although he built a hot spring bath, he didn''t think it was any good to use it alone before. Now that there are more people in the shelter, Chen Xin still feels that it is necessary to expand it. At least, men and women should be separated. It''s not necessary to say that every time he wants to use the bath, he has to divide the time between men and women.


    In addition, since it is necessary to carry out research and manufacture things, Chen Xin feels that the original workplace is a little smaller and should be adjusted.


    With the emergence of Chen Xin''s many ideas, the refuge on the drawing has become quite different.


    Not only a few more spaces have been created, but the overall floor area is even larger. Not to mention, the main part of the shelter, which was originally buried underground and had a drop of tens of meters from the entrance, has also been adjusted on the drawings. The drop between the two is now only one floor high.


    This height difference is not a problem in terms of building structure and protection performance. Originally, Chen Xin buried the main body of the refuge so deep, mainly to cope with the meteorite impact and subsequent disasters.


    Now that the disaster is over, there is no need to live underground.


    As for the water, electricity, heating and air filtration facilities, Chen Xin separated them from the main part of the building and set up a separate space to place them. In this way, these facilities no longer need to be placed in the main area of the refuge, and any problems will not affect the residents in the refuge.


    After some adjustments, it can be said that the overall planning of the refuge is more clearly differentiated, and several new production and living facilities are added, with more perfect functions.


    However, looking at the somewhat messy layout of the refuge, Chen Xin thinks that it should be adjusted.


    Although we don''t have to worry about the difficulty of construction and the lack of space, we should make the planning of the whole refuge more reasonable.


    Thinking of this, Chen Xin remembers a video he saw before about the federal rich transforming the shelter with abandoned missile silos. The shelter transformed from the missile silos in it is really good. Both the comfort level and the function perfection are very satisfactory, and the design is also very reasonable.


    So after thinking about it, Chen Xin decided to readjust the layout of his refuge.


    First of all, there is no need to lay out the newly added functional areas of the refuge, which can be stacked completely. The whole refuge is designed as a multi-storey structure, which can be up and down through elevators and stairs. In this way, the layout of the building can become compact and more convenient and practical.After all, in the shelter, going up and down stairs and turning around a few corridors are totally different experiences.


    Moreover, Chen Xin also plans to adjust the current four square shelter structure into a circular shape, following the example of a shelter transformed from a missile silo.


    This is not to say that Chen Xin is copying or imitating, but because the circle is relatively more efficient in space utilization and can be more convenient for layout.


    Of course, there is another point that the structural strength of the circular structure is stronger, and it saves more materials. Of course, Chen xinlai doesn''t care about this.


    Therefore, after some adjustments, the whole refuge has become a multi-storey cylindrical structure, which is still connected to the entrance of the refuge through the corridor, but it no longer needs to go down dozens of meters through the elevator to enter the interior of the refuge.


    Instead, it can reach the first floor of the main part of the refuge directly, and then go down to the lower floor through the elevator or stairs in the center of the circular structure.


    As for the main part of the refuge, Chen Xin separated the living room, kitchen and hot spring bathroom, which were originally connected with the bedroom. They were separately placed on other floors, and the bedrooms were concentrated on the first floor to increase the living area.


    After this adjustment, everyone can have a single room and a more comfortable bed, no longer need to sleep in high and low beds.

 Chapter 402

    "After the renovation, the shelter will be divided into seven floors, from top to bottom are the living room on the first floor, the living room, dining room and kitchen on the second floor, the working room and infirmary on the third floor, the bedrooms on the fourth floor, the bar and entertainment room on the fifth floor, the gym and fight training ground on the sixth floor, the swimming pool and hot spring bathroom on the seventh floor." Chen Xin showed the people in the shelter his revised design, and explained each floor.


    Looking at the design, Chen Xin''s father took the lead in asking questions, pointing to the two ancillary buildings on both sides of the main body of the shelter and asking, "these two should be the planting greenhouse and the power distribution room, right? You''re putting the water treatment and distribution room together? Is there a security problem? "


    "This part is the triple functional area of power distribution, air filtration and water treatment, with a total of three floors." Chen Xin looked at his father and asked, "because of the lack of space, the power distribution room and water tank were placed in the main part of the shelter. In fact, there were some hidden dangers and mechanical noise.


    So this time, I moved these facilities out and put them aside.


    The top layer here is the air filter, which is connected with the outside by the ventilation pipe. The air will be filtered before it is transported to the shelter. In addition, the oxygen transported from the planting greenhouse will also be mixed with the filtered air here to supply the needs of the shelter.


    The middle floor is the power distribution room, and the main power supply facilities are the three isotope thermoelectric batteries previously installed. In addition, there is a fuel generator, but it is only used in emergency.


    The bottom layer is the reservoir and water treatment equipment. Groundwater is pumped from the ground by the pump. Because of the relationship between hot springs, the water will be divided into two parts. One part will be directly transported to the hot spring bath after filtration, and the other part will be imported into the reservoir for domestic use.


    This is the overall situation. I have readjusted all the equipment. There should be no safety problem.


    In addition, it is put aside alone, even if there is a safety problem, it will not affect the main part of the shelter. The middle channel can be cut off, and the maintenance can also be entered through the maintenance channel at the top. "


    "We must pay attention to safety issues, especially water and electricity. When I was in the factory, I saw many safety accidents because I didn''t pay attention to some small details, so we must pay attention to them." Chen Xin''s father seems to be a bit nagging, but maybe he has been dealing with these things all his life for safety issues. He is very sensitive and careful about these things.


    Chen Xin nodded his head and answered in a positive way: "safety must be paid attention to. After the transformation, I hope you can check it every day. After all, you don''t understand it."


    "Well, tell me what you should pay attention to later." Chen Xin''s father nodded and agreed.


    Seeing that his father promised to be responsible for the safety inspection, Chen Xin immediately felt relieved. If an experienced technician like his father, who had been in state-owned enterprises, wanted to ask him to work before the disaster, he would have to earn at least 400000 a year. With his help to deal with these safety problems, Chen Xin could hardly feel relieved any more.


    "Do you have any other questions, or do you think you need to revise them?" Chen Xin took a look at the people in front of him and asked them again.


    "Ah Xin, what about the heating equipment? You used to install ground source heat pumps for heating. Now what about these ground source heat pumps? " Chen Xin''s father is concerned about the safety of water and electricity, but Mo Qingyan is concerned about another aspect.


    Chen Xin certainly won''t ignore the heating problem. He smiles and enlarges the design drawing in front of him. He points to a part of the floor where the swimming pool and hot spring bathroom are located at the bottom floor and explains to the public: "the original heating equipment was moved here by me. After hot water is extracted, it is cooled by the ground source heat pump and converted into heat energy to supply the circulation system to provide heat for the whole refuge, while After cooling, the water will be transported to the pool to maintain the temperature of the pool, and then it will be re transported back to the ground


    "The swimming pool is thermostatic?! It''s a luxury Qin LAN heard that Chen Xin would maintain the water temperature of the swimming pool. She could not help feeling that it was too luxurious.


    In this regard, Chen Xin did not avoid nodding his head, and answered positively: "it''s snowy outside, warm inside, hot springs and constant temperature swimming pool. It''s really a luxury. But since we have the conditions, and we have passed the difficult stage, I think it''s no problem to live a better life and improve the quality of life."


    "Well, it''s really no problem." Although Qin LAN doesn''t agree with luxury life, she still nods and doesn''t refute Chen Xin.


    Chen Xin also noticed Qin Lan''s attitude, but also did not say anything. Since Qin LAN is not firmly opposed now, Chen Xin knows that she still supports herself, just a little unhappy. There is no need to put it in front of everyone. When they are alone at night, Chen Xin can naturally comfort and persuade her.


    "Since you want to live a more comfortable life, you can just use the kitchen better, so that you can eat more comfortable." Chen Xin''s mother also put forward her own suggestions or requirements at this time. After all, after she came, the kitchen of the shelter was mainly used by her, not Chen Xin, who is the best cook among all.Chen Xin just nodded and agreed to his mother''s request. This kind of request is really simple, and there is nothing to say.


    But Han Ping and Han Ze, who usually don''t talk much, raised their hands and said, "Mr. Chen, can you improve the accommodation of the observation room above? It''s still cold at night. "


    "Well, this is also one of the key points of this upgrade. After this upgrade, a new adjustment will be made to the observation room on the top. I will improve the accommodation of your two brothers. In the future, you two will no longer have to stand guard at night." Chen Xin half jokingly explained, but also adjusted the blueprint, explained to Han Ping and Han Ze: "after the outside, there will be a communication base station, which will be able to access the country''s current communication network. In the future, your two brothers'' work is to maintain communication, and security issues will be taken over by special forces."


    "Will the special forces stay here in the future?" Han Ping naturally knows the special force that sent Chen Xin back, but he doesn''t know that this force will stay here. In the future, Chen Xin''s security problems will be in their charge.

 Chapter 403

    When Chen Xin was planning how to upgrade his shelter, the engineering and technical personnel sent by the state also arrived in the city and came to Chen Xin''s shelter to discuss with him how to build a scientific research base and military camp.


    Theoretically speaking, these problems do not need to be discussed with Chen Xin. We just need to consult him to determine what he needs and then we can build them step by step.


    But Chen Xin''s situation is somewhat different, so the engineering and technical personnel of Fu and the researchers assigned to the scientific research base need to contact and negotiate with Chen Xin to determine what Chen Xin''s needs are, and then what aspects he mainly studies.


    Only when these are confirmed can the scientific research base specially built for him confirm how to build it.


    What''s more, Chen Xin also proposed a new design scheme, which requires engineers and technicians to connect with him.


    "So academician Chen of this scientific research institution, do you want to build a closed structure, and then build a small ecosystem inside?" After listening to Chen Xin''s idea, the researchers who originally came to contact Chen Xin quickly understood what he meant and said with great approval: "this is a very meaningful research topic! If we can build a small self recycling ecosystem, it will be of great significance to rebuild the ecological cycle of the whole earth after the natural environment is restored! "


    "I haven''t thought about it for a long time. The main purpose of the research on small-scale ecosystem is to study ecological agriculture, to consider how to improve food production for the country, and to make myself comfortable by the way. In addition, I haven''t really thought about that much." Chen Xin didn''t consider the things mentioned by the scientific researchers. The ecological environment of the whole earth is far away from him.


    And even if we really have to consider these problems, Chen Xin has a better choice. He does not need to study how to restore the whole ecosystem through a small ecosystem.


    World engine, planetary transformation, mega dome, ring the world There are so many technologies that can be used. Although a small ecosystem technology can be regarded as the basis of these technologies that affect the whole planet, it really doesn''t need to be too concerned.


    "It''s a long way to recover the global ecology, but it''s still very meaningful to study the self recycling ecosystem. Apart from other things, it''s very worthwhile to recover the biological samples before the disaster." The researchers are obviously enthusiastic about this, and specially told Chen Xin: "before the disaster, the country preserved a large number of plant seeds and animal embryos, all of which were frozen in the life seed banks of Kunlun Mountains and Himalayas.


    If we can build a self recycling ecosystem, we can use these preserved plant seeds and animal embryos to restore the animals and plants before the disaster! In this way, we can restore the precious animal and plant resources and not leave a barren world for our future generations. "


    For the excitement of the scientific research personnel, Chen Xin seems a little indifferent, and the engineering and technical personnel on one side also have the same expression.


    It''s not that they don''t pay attention to the significance of this event, but they think that what the researchers mentioned is too far away.


    After all, people all over the country are still facing the problem of food and clothing. It''s really too far away to think about how to get more food to feed people all over the country and how to restore animal and plant resources and the earth''s ecology.


    Even if this research is meaningful, it will not make sense until we have enough to feed and ensure that more people live.


    However, Chen Xin did not dampen the enthusiasm of the scientific research personnel, and they still need to do the research work in the future. If the enthusiasm of other people is dampened, the research in the future will not be good.


    So Chen Xin waited until the scientific researchers calmed down, then he continued to say to the engineers and technicians: "after the dome is built, the interior is mainly used for the research of small-scale ecosystem and ecological agriculture. In addition, the scientific research department also needs to carry out reverse research on the things I made, and assist me to complete the upgrading of the research projects transferred by other research departments.


    So in terms of scientific research facilities, we may need to be all inclusive and have everything, because I don''t know what to study and what to use. "


    "In that case, it might be a bit of trouble! If there is no definite direction, the construction of this research base will be very troublesome. " Engineering and technical personnel can''t help but frown at Chen Xin''s request.


    Although we know that this task is different from the past, the most difficult thing to meet is that there are no specific requirements and there are all kinds of requirements, which makes the engineering and technical personnel feel difficult.


    We should know that different research directions have different requirements for research facilities. Some require dust-free, some require aseptic, some require absolute cleanliness, and even require vacuum environment Even with ready-made drawings and now integrated modular shelter, the construction of these research facilities is very troublesome.


    Not to mention that some large research facilities need to be specially designed to accommodate them.


    At this time, the researchers on one side could understand Chen Xin''s meaning. After thinking about it for a while, they said, "that is to say, we need at least a biological laboratory to study the small ecosystem, a physical laboratory and a mechanical laboratory. As for the others, I think we can put them back and leave space in advance Add when necessary. ""Well, I don''t have a problem with this plan, but the research of small ecosphere is not only a biological laboratory, I also need a greenhouse for agricultural research." Chen Xin added.


    The engineering and technical personnel''s face looks good. At least they don''t have a clue.


    "By the way, since the research facility will use a fully enclosed dome structure, how can the internal heating problem be solved? Is it electric heating or boiler heating? " Engineering and technical personnel asked Chen Xin that these are all things that need to be confirmed before the construction starts, and they must be determined one by one before the construction can start.


    "In terms of heating, I plan to use geothermal heating, and the related technology is the deep geothermal energy tower technology that I put forward when I was near the city." Chen Xin obviously does not plan to use electric heating or boiler heating, but adopts the new technology he proposed in Linshi: "building an energy tower near here can just heat the whole research facility. Needless to say, the excess heat energy can also be used to generate electricity."

 Chapter 404

    After confirming the relevant requirements from Chen Xin, the preparatory work of the research base soon began.


    Different from the research base that needs to design drawings first and then consider how to construct on site, the camp of the special forces was soon established outside Chen Xin''s refuge.


    The former mobile barracks, however, were upgraded by Chen Xin. They became easier to set up and move, and their thermal insulation performance was better. Therefore, the construction was soon completed, allowing these special forces to settle in.


    However, this is only a temporary camp. After the construction of the scientific research base is completed, these special forces will move to the permanent camp built together with the scientific research base.


    On the issue of permanent camp, Chen Xin also discussed with the political commissar of the special forces, because Chen Xin is not sure whether they are permanently stationed here, so some issues must be discussed.


    Fortunately, this army has been given clear instructions before it comes. They will be responsible for protecting Chen Xin until they receive new orders.


    And they also received new instructions from the higher authorities. After the construction of the scientific research base is completed, they will be stationed here to take charge of the security work of the scientific research base.


    This reassured Chen Xin a lot, and at the same time, he had plans for the construction of barracks.


    After all, if this special force is not stationed here, but other troops or armed police are transferred here, some facilities in the barracks will have to be changed.


    If it''s special forces, Chen Xin can confidently and boldly hand over some of his improved weapons and equipment to them, but if it''s ordinary forces and armed police, some of the equipment obviously can''t be handed over to them so directly.


    Although the special forces, the ordinary forces and the armed police forces are all Yanguo''s troops, there are many differences between the troops in terms of equipment and confidentiality level.


    Now that it has been determined that the army will continue to protect itself, Chen Xin will be able to confidently and boldly provide some obviously black technology weapons to the special forces.


    For example, Chen Xin once again provided them with enough heavy machine armour to arm two combat teams, so that this special force can go a step further in heavy equipment.


    In particular, Chen Xin has kindly replaced the 12.7mm revolver gun originally equipped on the right shoulder of the mecha with a 50mm portable short barrel recoilless gun, and installed a short chain saw on the right arm of the mecha, which makes the heavy mecha more and more like the terminator armor in the 40K hammer.


    Of course, the army is overjoyed with the equipment provided by Chen Xin. Which army doesn''t like this kind of hard and thick pipe?


    What''s more, they are shouldering the mission and task of getting new equipment from Chen Xin. Now with Chen Xin''s initiative, they can easily complete the tasks assigned by their superiors. Why not?


    As for their military superiors, after seeing the heavy mecha provided by Chen Xin, they are so happy that they can''t see it. They just want more and have no opinions.


    Although many people say that the mecha is not as good as the tank in terms of firepower and defense, the mecha is more flexible and can be deployed more flexibly than the tank.


    In the environment where it is not convenient to deploy tanks, mecha can just fill in the lack of defense and firepower support in infantry operations, provide strong support for the army, and fill the gap in this aspect of the army.


    After these heavy mecha are equipped to the special forces, the military even plans to send operational experts to study how to use these heavy mecha and formulate new operational tactics for them.


    This also led to Chen Xin''s addition of a military combat research laboratory in addition to different scientific research laboratories.


    Chen Xin is also happy with this. After all, he plans to make something more interesting. With the help of the military, many problems are much simpler.


    In terms of design drawings, because of the special environment of the end of the world, many private design companies can not continue to exist, and only the design institutes belonging to the state organs can undertake the design work in the present environment.


    Chen Xin''s scientific research base is in charge of a design institute in Xingcheng, the capital of Hunan Province.


    The reason why he wanted to go to the Design Institute of Xingcheng is that Chen Xin is located in Hunan Province. Before, he had been dealing with the three towns of Hubei Province, and the leaders of Hunan Province had a lot of opinions. Therefore, the design and construction of the scientific research base was snatched by the leaders of Hunan Province, in order to have a good relationship with the academicians of the highest Academy of Sciences in the province.


    In design, the design institute intends to use steel span beams as supports, and then use light materials and tempered glass to make the dome.


    In fact, there is no difficulty in the design. Although the diameter of 500 meters sounds exaggerated, similar applications have been used in airports, high-speed railway stations and gymnasiums for a long time, which is nothing for Yanguo, a big infrastructure country.


    The design institute didn''t do anything about this either, and soon came up with the first version of the design.


    The overall shape of the ecological dome is similar to that of the yurt. The slightly curved circular dome is supported by 12 ge shaped supporting columns, while the circular dome itself is erected on the supporting columns by light materials in a form similar to a bucket arch, and then the hexagonal honeycomb structure of tempered glass is laid as the dome.On the whole, the design institute didn''t play any fancy. It adopted some very avant-garde designs. On the whole, in addition to the hexagonal honeycomb structure of glass, other places can even be described as simple.


    However, it is no wonder that it is impractical to build a building with a sense of design in this environment. Everything should be practical rather than artistic.


    Although there are also designs that take into account both art and practicality, at present, they should be practical.


    Only when there is spare power can we give consideration to the sense of art.


    After determining the design scheme, it is naturally the drawing of detailed construction drawings, as well as the preparation of related materials and parts.


    However, there is a thorny problem here, which almost makes the project impossible.


    The twelve supporting columns needed to build the dome are large-scale metal components. Because of the need of supporting strength, the whole structure needs to be integrated. However, affected by the disaster, Yanguo''s industrial production capacity, which is still recovering, cannot complete the processing of such large-scale metal components.


    According to the design of the Design Institute, the height of a support column is more than 30 meters, and the transverse branch is more than 50 meters long. If you want to process it as a whole, you need to ensure the support strength. You can imagine the high requirements of the processing technology.

 Chapter 405

    A steel structure more than 30 meters high and more than 50 meters long can''t be made, which is very strange in the state of Yan.


    If before the disaster, bigger and more demanding metal components had been made, Yanguo people would never be limited by the rule.


    However, in a country where a large number of industrial production capacity has been affected, it is really very difficult to make such steel members. Without sufficient industrial base, it is really impossible to do so.


    Of course, there are solutions. As a big country in infrastructure construction, Yanguo has its own alternatives.


    Of course, the simplest way is to change the design, and replace the current supporting column scheme with more columns and supporting beams that can be processed or simply poured with reinforced concrete. The construction of the dome can also be completed, but correspondingly, more supporting columns need to be added inside the dome.


    Such a scheme is more practical, but more supporting columns in the corresponding dome will have an impact on the internal space. Although the planning is reasonable, it has little impact, but in the end, it is not as good as a transparent overall structure.


    The second method is to use the welding process to manufacture the parts of the support column in sections, and then assemble them by welding.


    This method can naturally meet the requirements. Yanguo''s welding process can already meet the requirements, but on the whole, segmented welding will still have an impact on the support strength, which is not as strong as integrated molding.


    Both schemes can play an alternative role, but scheme 1 affects the space utilization, and scheme 2 affects the structural strength. The design team can''t make a choice for a moment, so it can only send both schemes to Chen Xin for Party A to make a choice.


    The design team is not throwing the pot, and they also want to see if Chen Xin can come up with other solutions.


    Chen Xin, is there a solution here?


    The answer, of course, is yes.


    "There are two solutions to this problem. One is that I can make a machine that can process steel members of this size to process the required things, and the other is that I can use 3D printing technology to print the required things." Chen Xin doesn''t think the problem is too difficult to solve. He also gives two solutions.


    "What are the characteristics of these two schemes? Is the structural strength enough for 3D printing? " The engineers and technicians who came to submit the scheme to Chen Xin asked Chen Xin that although 3D printing technology has developed rapidly in recent years, no one dares to say that its own technology can be used to print such a large metal structure.


    Moreover, even if such a large metal structure can be printed, how can 3D printing ensure that the printed components can meet the requirements in strength?


    As for Chen Xin''s manufacturing of a machine capable of processing components of this size, engineers and technicians have no doubt that Chen Xin can do it.


    "It''s not good to build a machine to make components. Apart from the updating of processing accuracy and processing technology, it''s basically similar to the normal processing of such components. It''s just that my machine may consume less energy and produce better components." Chen Xin gave a simple explanation, and did not give more explanation to his first proposal.


    However, for 3D printing, he said with great interest: "as for 3D printing, this technology is basically the same as the existing technology on the market, which is spraying materials through nozzles, and then melting and solidifying the materials through laser sintering, so as to form a stable structure."


    At this point, Chen Xin stopped for a moment. After the engineers and technicians had digested what he said, he continued: "however, the laser sintering technology I used is better than the one currently on the market, and the sintered materials are more durable in structural strength.


    In addition, the technology I provide does not need a sealed environment to strictly control the air flow and air humidity. It can be applied to the printing and manufacturing of large structures or buildings. Even in the raw materials, it is also possible to use ordinary metal powder to feed in proportion, and then print the alloy. "


    "Can I print alloy?" There was a look of surprise on the engineer''s face.


    If you just print large metal components, this is not enough to shock engineers and technicians, but directly mixed with a single metal powder can be printed out of the alloy, this technology is somewhat incredible.


    The alloy manufacturing department is not only mixing metals together, but also different treatments are needed to obtain different properties.


    It''s like the stainless steel tableware in your home and the shipbuilding steel for warships are made of nickel chromium alloy, but there is a great difference in performance between them.


    However, this is nothing for Chen Xin. Even if he wants to build a molecular metallurgical furnace, it is no problem. It is also possible to directly decompose various materials from the molecular level, and then rearrange and combine the molecules according to the needs to obtain the materials he needs.


    Of course, this level of metallurgical technology is too exaggerated, and Chen Xin is not ready to make it.


    Just now this kind of 3D printer that can print alloy is enough."It''s hard for me to explain the specific principle and technology, but you just need to know that I can do it." Chen Xin is still a "I just do things, you study the principle of your own" attitude, but he also said: "I can do a small, you take it to test, see the effect."


    "That would be the best!" At this time, the engineering and technical personnel have been excited to say nothing more. They are just looking forward to the 3D printer that Chen Xin promised to print alloy.


    If Chen Xinzhen can achieve this, even if he just prints some simple alloys, it will have extraordinary significance in practical application.


    Chen Xin naturally saw the excitement of the engineering and technical personnel in front of him. For Chen Xin, this kind of scene that someone was excited because of his own words has been seen too much, and he didn''t respond to it all the time, so he just nodded and said: "I''ll make a small prototype for you first. You can take it to experiment and confirm the effect Let''s talk about the subsequent construction plan. "


    "Yes, academician Chen!" Engineering and technical personnel agreed, the excitement in the heart is not easy to suppress down.


    As for the change of the construction scheme, of course, it is also a proper meaning. If it is a traditional construction scheme, it needs to build a shelf and be installed and welded by workers bit by bit.


    But if you use 3D printing, you can build a high-rise building from the ground. You don''t need so many construction workers. You just need to let the 3D printer print out the main structure by itself, and then let the workers handle the follow-up work.


    They are quite different in engineering quantity and construction difficulty.

 Chapter 406

    As we all know, in nature, metals exist in a combined state, that is, they form so-called compounds.


    Only those extremely inactive metals exist in the form of simple substances, such as gold, silver, platinum, palladium These precious metals are also known as inert metals because they are stable and difficult to react with other substances.


    Therefore, most of the metals that human beings can obtain in nature are minerals in the form of compounds, which need to be smelted to obtain new metal elements.


    However, the physical properties of pure metal are single, which often can not meet the needs of use.


    For example, the well-known iron, in fact, pure iron is very soft. Only when it is combined with carbon to form an iron carbon alloy, can it have a hard texture.


    According to this physical property, we can process the iron carbon alloy at different temperatures to obtain iron carbon alloy with different properties, which is commonly known as steel.


    The history of using alloy is very long, which can be traced back to the ancient Babylonians more than 6000 years ago. They are the earliest known civilization that began to smelt bronze, that is, copper tin alloy.


    In the Shang Dynasty more than 3000 years ago, the ancestors of Yan people had been smelting and using bronze on a large scale, and even could obtain sharp swords by forging and other processing methods.


    The famous Yue King Gou Jian sword is still extremely sharp even after thousands of years. It can cut more than ten layers of paper with one stroke.


    So in human life, alloy can be said to be everywhere.


    But it''s still very difficult to print alloys with 3D printing.


    First of all, theoretically speaking, this can be done, because the definition of alloy is a kind of solid product with metal properties obtained by mixing and melting one metal with another or several metals or nonmetals, cooling and solidification.


    Therefore, to print alloys by 3D printing, in theory, we only need to mix the elemental raw materials of metals according to the required ratio, and then process them by laser to obtain the required alloys.


    But it''s not easy to do that.


    First of all, the mixing of metal powder must be very uniform in the overall proportion of raw materials for each sintering. Otherwise, the metal proportion will produce errors, and the printed material performance will also have problems, which will damage the overall structure of the printed product.


    Before the disaster, Bluestar had laser 3D printing technology, and even someone printed a set of iron man armor with titanium metal, which can resist rifle fire.


    But this is in the closed equipment will be covered with metal powder only about 0.1 mm or even a few microns of a layer, and then laser sintering in the area to be printed.


    So repeatedly, layer by layer after sintering, the parts can be printed out.


    In this process, if there is airflow disturbance, it will directly blow away the unfired metal powder.


    For the time being, it is difficult to print large parts and alloys due to the harsh conditions.


    If only the powder particles that have been processed into alloys are sintered, it is naturally very simple, but it is not so easy to process metals with different elements into alloys.


    Because a very important factor here is the temperature.


    Sintering is to process at a temperature slightly lower than the melting point of the material, so that the powder particles are bonded. However, it is obviously impossible to process different materials into alloys only by sintering.


    What''s more, if we want to obtain some special alloys, the processing temperature is even much higher than the melting point of the material, and we need to maintain the temperature for a certain period of time to make the material properties change fully.


    And these are exactly what 3D printing technology is now difficult to achieve.


    But these are not problems for Chen Xin. He can melt the single metal powder particles with laser, mix different metal elements together to form an alloy, and then cool and sinter the alloy to become the required parts. All the 3D printers he makes can do it.


    And Chen Xin''s 3D printer doesn''t print through a fixed frame and print head like traditional equipment, but looks like a small robot.


    A small robot carries part of the raw materials, melts them into alloy according to the pre-designed procedure, and then prints them.


    When there are enough robots, a large part can be printed quickly.


    The inspiration of this technology comes from some science fiction games, in which the so-called nano robots are often used to make objects through 3D printing, which Chen Xin learned from.


    It''s just that he didn''t make the robot that small, but made it into a small UAV.


    After he agreed to make a small prototype for the engineers and technicians, Chen Xin quickly finished the prototype through the worktable and manipulator in the shelter, and also upgraded it."This It''s amazing Engineers and technicians can''t help but wonder when this small 3D printing robot like UAV prints out a miniature model of the Eiffel Tower in front of their eyes.


    "This is the small prototype of 3D printing equipment. According to the actual needs, it can be bigger or smaller. The size at present is more common in various occasions." Chen Xin showed the prototype of the 3D printing equipment while introducing it: "it can carry about two kilograms of raw materials at a time. It can be processed alloy powder or a mixture of metal powder. It can be printed online by multiple equipment to print the required large metal components."


    "With this, building construction will be much easier!" Engineers and technicians have begun to imagine hundreds of such 3D printing robots working at the same time, making buildings grow like bamboo shoots in the ground.


    "Well, it''s not only for building construction, it can also be used for mechanical manufacturing and metal processing. The advantage of using 3D printing is that the printing accuracy is enough, the printed metal parts don''t even need to be processed, and no matter how strange the shape you need, it can be realized for 3D printing." Looking at the excited look of the engineering and technical personnel, Chen Xin said with a smile: "for some fields that need high-precision parts, this is very useful."

 Chapter 407

    "After our discussion after synthesizing the opinions of all parties, the final design is like this." In the living room of Chen Xin''s refuge, the designer in charge of submitting the design scheme is introducing the whole design scheme to him: "the maximum diameter of the main part of the ecological dome is 512M, the arc of the dome itself is 1.1rad, which is a round structure, the diameter of the ground part is 496m, and the maximum height of the dome is 41.2m. The whole building is divided into three floors above the ground and one floor underground.


    The central part is a small ecological circle and a heating hub which provides heat for the whole building. The main part of the building is distributed in a ring around the atrium.


    The above ground part is mainly used for the placement of various laboratories, while the underground part is used as a weapon testing ground and storage warehouse, and space may be reserved for underground experimental institutions in case of emergency. "


    After listening to the structural introduction of the main part of the ecological dome by the designer, Chen Xin was quite satisfied with the design, but after thinking about it, he still asked, "where are the military camp and the planting greenhouse I mentioned earlier, and do you plan to use the heating hub to heat the ecological dome?"


    "Yes, the heating hub and energy tower technology is a very efficient way of geothermal utilization, and can be directly converted into electric energy. Compared with another power plant for power supply and the construction of a boiler for heating, the construction of geothermal power plant can not only obtain efficient and clean energy, but also heat the ecological dome, which is much less than other schemes." Obviously, the designer considered a lot of schemes before finally choosing the current design scheme.


    Chen Xin didn''t say much about it. Although the technology came from him, he didn''t feel proud or other emotions about it. He just nodded his head and said, "it''s enough to use the heating hub to heat the ecological dome, but it seems that power supply is another calculation according to your opinion?"


    "Yes, according to our design, we should build an energy tower near the ecological dome to extract underground heat, mainly for power generation, and the remaining energy will be transmitted to the heating hub in the ecological dome for heating, and the circulating medium will be re injected into the ground through the return well under the heating hub." Since the designer will adopt this scheme, of course, he has a detailed understanding of the relevant technology.


    "Well, it''s a good application. It can generate electricity and heat. It''s very good." Chen Xin nodded and was sure of the design of the scheme, but he looked at the design drawing and continued to ask, "so you put the planting greenhouse and military camp outside the ecological dome? Although connected together, it is not placed in the main body of the ecological dome? "


    "That''s right, because according to our calculation, it''s not impossible to put the planting greenhouse and military camp in the ecological dome, but it will make the internal space crowded out and appear very cramped, so it''s better to adopt such a design that can be spread out." The designer elaborated his design concept and explained it on the drawings: "we design the direction of the barracks as the main entrance. If we want to enter the ecological dome area, we must pass through the area where the barracks are located. In this way, it can also play the role of security and inspection.


    The other two sides are geothermal power plants and planting greenhouses, which are respectively located on both sides of the ecological dome, so that the whole presents a triangular layout, so that each part can obtain enough space, at the same time, the arrangement is relatively close. "


    "You know better than me in this aspect. Just follow your design. As long as you can meet my needs, nothing else will be wrong." Chen Xin did not express different opinions and opinions on this. After nodding, he continued to ask, "what are you going to do in construction? Use heating hub to bake snow and then level the ground for construction? "


    This is the method Chen Xin used in Linshi railway station before, and it is also his original intention to design the heating hub. Considering that there is also more than ten meters of snow in front of his home, Chen Xin first thought of this construction method.


    "Yes, so we will complete the construction of the geothermal power plant and the heating hub first, and then the construction of the ecological dome and other buildings." In the face of Chen Xin''s question from Party A, the designer answered his question in great detail, saying everything: "after the construction of the geothermal power plant and the heating hub, we will first lay the foundation for the ecological dome, and at the same time start the construction of the military camp.


    After the foundation is laid, the supporting part of the main steel structure of the ecological dome will be constructed through the 3D printing robot provided by academician Chen. After the overall completion, the glass exterior wall and internal structure of the dome will be laid. "


    "Are glass walls reliable? Now, although the frequency of meteorite fall has been reduced a lot, but still occasionally see scattered meteorite debris fall to the surface, right? How do you think about this? " No wonder Chen Xin has such doubts. After all, the disasters of Bluestar are all caused by meteorite impact.


    More than a year ago, even though Yanguo was not the main disaster area hit by meteorites, we could often see firestars falling down from the sky.


    In such a case, it is not necessary to say whether it can resist the sporadic meteorite impact, but at least it should be ensured that after the impact, the whole building''s external walls will not be completely broken, and all the things that need to be rebuilt will not happen.


    "What we use is a multi-layer composite structure of glass exterior wall, the main material is tempered glass, and the sandwich is made to prevent crushing. At the same time, the glass itself has a heat absorbing coating, and the light transmittance can be adjusted according to the light intensity, so as to ensure maximum access to natural light and light radiation, and to have the effect of keeping warm." Obviously, the designer has given full consideration to this. He specially found out the design of the glass exterior wall from the drawings and said to Chen Xin with pride: "considering the possible meteorite impact, we adopt the hexagon honeycomb splicing design for the glass exterior wall. If the impact occurs, although some of the glass may be broken, it will not let the glass break through The bottom is crushed.Moreover, we have also made adjustments to the internal structure of the building. Even if there are many factors such as internal explosion or meteorite impact, the impact on the glass exterior wall will not be very strong, and it will not lead to the fragmentation of all the glass exterior walls of the whole building. "


    "If so, I have no other opinions. Let''s start the construction according to your design." Chen Xin felt that he knew enough, so he clapped his hand and said, "as for the 3D printing robots needed for construction, I will deliver them to you before we start."

 Chapter 408

    Because of the high-level Hunan Province want to win over Chen Xin, a new academician, the construction of the ecological dome started very quickly.


    After finalizing the design drawings and providing a 3D printing robot for the construction, the front of his shelter soon became a hot construction site.


    Two drilling rigs transferred from Hunan Province started at the same time, one is responsible for drilling the pumping well of the energy tower of the geothermal power plant, and the other is responsible for drilling the return well of the ecological dome heating hub. At the same time, another construction team is in the process of pipeline installation.


    Because of the simultaneous construction of many groups, the front door of Chen Xin''s house is very busy and noisy, and the special forces stationed are also on guard against this situation.


    Although Chen Xin''s refuge has a defense comparable to the main armor of a battleship, and heavy machine guns are installed on both sides of the gate, Chen Xin can completely achieve internal self-sufficiency when he doesn''t go out, but the commander of the special forces who has dealt with the affairs in the city still feels that he is not safe enough.


    Therefore, in addition to entering the construction area and inspecting the construction site, they also mobilized some people to set up sentries at the gate of Chen Xin''s refuge to prevent all the others from approaching, so as to ensure Chen Xin''s safety and avoid the same thing as last time.


    Nevertheless, Chen Xin can not always stay in his own shelter.


    "Academician Chen, I''d better advise you not to go out." Facing Chen Xin who wants to go out, the new officer who replaces Wang Hailai as Chen Xin''s security guard tries to dissuade Chen Xin from going out.


    In the face of the officer''s dissuasion, Chen Xin put on a very helpless attitude and said: "Lieutenant Deng, you can''t stop me from going out, can you? What''s the difference between that and putting me in jail? "


    "But academician Chen, your safety problem..." The second lieutenant Deng was obviously told by his superiors before. In any case, he should pay attention to Chen Xin''s safety: "although the assassination in Linshi has come to an end, academician Chen, if you go out, you may still encounter danger. I must ensure your safety!"


    "If you want to ensure my safety, you can go out with me and deal with any danger in time, instead of saying that for my safety, you won''t let me out of the door." Of course, Chen Xin understood that this second lieutenant Deng was kind-hearted, but he promised to let the state send someone to protect him, not to be restricted in his freedom.


    As for safety, after the last incident, Chen Xin really reflected on himself. He not only began to learn some basic Sanda and fighting skills with Qin LAN, but also improved his equipment.


    Power armor is of course Chen Xin''s first choice, but Chen Xin''s previous power armor is too heavy and bulky. Although it is safe to wear, it is not convenient and flexible enough.


    As for the exoskeleton, of course, it''s also a good choice, but unless it''s equipped with a military protective plate, the exoskeleton''s protective performance is not much different from that of not wearing it.


    For a variety of reasons, in fact, the ghost agent''s protective clothing in StarCraft, the well-known iron man armor, and the nano combat clothing in graphics card crisis are more suitable for Chen Xin.


    On the one hand, the protection ability is enough, and on the other hand, the two are light and dexterous, so they are not too bulky and bulky.


    It''s just that Chen Xin of the previous generation of iron man armor didn''t like it very much. Only the last generation with nanotechnology design made him like it very much. However, if he wanted to restore the reality, he had to smash in tens of thousands of survival points to make it.


    The ghost agent''s protective clothing and nano combat clothing are relatively simple. It''s very easy to make a similar set of equipment without deliberately restoring the unscientific and non magical settings in the game.


    Only in this way, the products become very common. Chen Xin might as well wear military exoskeleton armor.


    Therefore, after some twists and turns, Chen Xin still gritted his teeth, relying on the current rich survival income, just smashed out a set of nano armor similar to the iron man battle suit in the movie.


    However, Chen Xin''s nano armor is still different from mark 50 and mark 85 in the movie. At least, Chen Xin doesn''t use gold and red to match colors. Moreover, Chen Xin doesn''t insist on putting the energy core on his chest like a light bulb.


    The final nano armor is a watch fastened on Chen Xin''s wrist. When he needs it, he will release a large number of nano units to cover his whole body, and then form a set of protective armor.


    According to Chen Xin''s own test, it takes about three seconds for the whole set of nano armor to cover the whole body from zero. Although it is not very fast, it is enough to cope with most cases.


    Of course, Chen Xin also considers the possibility of encountering unexpected situations, so the watch in his hand also has the function of energy shield, which can form a close energy layer on his body surface to resist external invasion without causing any obstruction or dead angle.


    In terms of the strength of the shield, even if it is shot with a large caliber anti equipment sniper rifle, it is impossible to penetrate the shield.


    It is precisely because of such protection that Chen Xincai has enough confidence in his own safety and dares to go out.Otherwise, after being assassinated, he is very concerned about his own safety.


    Originally, Chen Xin was not willing to show his nano armor and energy shield to others. However, looking at Deng''s attitude of "no matter what reason you have, I''ll never stand still" when he stopped him, Chen Xin started his nano armor after thinking about it.


    Because of the need to use nano armor, Chen Xin now generally wears the driving suit of power armor directly on his body, but he doesn''t wear a helmet.


    In this way, the nano armor can be deployed in the shortest time without being hindered by the clothes you wear.


    Deng was obviously stunned by Chen Xin''s nano armor. He watched Chen Xin put on a layer of silver glittering liquid armor in an instant, and then in the blink of an eye, the whole armor became dull. Deng had no chin and fell to the ground. He was very calm.


    Of course, maybe he was stunned.


    In a word, after showing off his new equipment, Chen Xin asked Lieutenant Deng, "this is my newly made nano armor. Its defense can withstand the direct attack of rocket launcher. In addition, you can follow me with all your equipment. Is there no problem with safety? If someone can hurt me under such protection, it''s useless even if I stay at home. "


    In the face of Chen Xin''s remarks, Lieutenant Deng hesitated for a while before saying, "I want to ask the captain and political commissar for instructions."

 Chapter 409

    The appearance of nano armor is obviously beyond the imagination of commanders and political commissars. They thought Chen Xin would not exaggerate even if he made something, such as liquid bulletproof vest.


    After all, Chen Xin gives people the impression that he is a kind of technical talent with explosive hands-on ability. However, what Chen Xin brings out is science fiction products in the true sense that are completely beyond the scope of existing science and technology.


    The so-called nano armor has different performance in different science fiction works. In the movie, iron man battle suit realizes various functions and changes the shape by controlling the core to arrange nano molecules into armor.


    The nano clothing in "graphics card crisis" is different from it. It has a fixed shape. It is only made of nano materials. When needed, it can switch between different modules to achieve different functions of war armor.


    Nano suit is just ordinary combat armor. Although the performance effect is cool, it is much worse than iron man suit in the movie.


    Through the different arrangement of nano molecules, the combination of components with different functions can be realized, and various abilities can be exerted. From the perspective of visual performance and film effect, it is really cool.


    From a practical point of view, nano armor is also very practical, because it is composed of so-called nano molecules, which can be arbitrarily arranged and combined, and new molecular structures can be obtained at the micro level, so that they have a variety of physical properties.


    At the same time, it can also form various components with different functions from the macro level, which can play a role no matter what kind of environment.


    Just like in the movie, it''s a hammer when it needs a hammer, a gun when it needs a gun, and a shield when it needs a defense


    To equip a suit of armor is to have the function of countless sets of armor. It can be said that there is no equipment that is more popular with the logistics and front-line soldiers, because only one piece of equipment is needed to meet all the needs.


    And logistics does not need to worry about all kinds of different sizes and specifications of ammunition, nor does it need to worry about the increasingly cumbersome and complicated types of equipment of the modern army. It just needs to send nano molecules to the front line.


    "As you can see, this nano armor can be turned into a power armor in three seconds, and it can also be turned into a shield to resist the attack of weapons. With the close protection of my combat team, I don''t think there will be any problem with my safety." He showed the commander and political commissar his nano armor and conducted a close range shooting test. Chen Xin was very relieved about his safety.


    As for Chen Xin''s security problems, in fact, after he showed nano armor, the commander and political commissar were no longer worried.


    They are concerned about another issue at this time.


    "Academician Chen, can this nano armor be mass produced?" The commissar looked at Chen Xin with burning eyes and asked him.


    Chen Xin touched his nose, shook his head and said, "I can do it, but the current domestic industrial production capacity I can''t do it, but if it''s a nano suit like "island crisis", it''s OK to make some elite troops in small quantities at any cost. "


    After all, Chen Xin has provided a lot of good things to the military, and they have not reached the point where Chen Xin cares about every good thing.


    Moreover, commanders and political commissars also understand that there is a gap between the conceptual equipment that can be made in the laboratory and the stereotyped equipment that can be used to equip troops.


    "So I can go out now?" After taking the nano armor back into the wrist watch, Chen Xin looked at the commander and political commissar and once again expressed his wish to go out.


    It has been confirmed that Chen Xin has the ability to protect himself, and the commander and political commissar are not good enough to continue to stop Chen Xin from going out. After a discussion, they agree to Chen Xin''s request.


    However, when Chen Xinzhen finally went out, he kept up with Deng''s combat team and sat in an armored car.


    "Speaking of it, does the man who assassinated me in Lincheng have any accomplices? You''ve been in such a big fight that I thought he had some friends who were thinking of taking my life at any time! " Sitting in the armored car, Chen Xin can''t help joking with Lieutenant Deng.


    Although Chen Xin was greatly affected when he was assassinated before, after the incident passed, especially after his safety was re guaranteed, Chen Xin was able to look at it with a more relaxed attitude.


    "We have interrogated the person who assassinated academician Chen in Lincheng. We have confirmed that he is indeed a person, and no relevant accomplice has been found." Compared with Wang Hai, Second Lieutenant Deng was more straightforward. Facing Chen Xin''s question, he answered in great detail: "this man was originally a mercenary in Nanyang area. Because of this disaster, he came to this city. The terrorist attacks in the urban area before were launched by this man and his accomplices."


    "It''s him!" Chen Xin suddenly realized.


    He heard Qin LAN talk about it before. At that time, although most of the terrorists were arrested, there were still two people fleeing. One of them was killed and only one was missing.Originally, the police did not carry out a large-scale search because of the current bad environment, and thought that the other party would be frozen to death because of the cold, but did not expect that he actually fled to the city.


    "This person is really not simple, this kind of weather can walk from the city to the city." Chen Xin can''t help but sigh, it''s obvious that AZU''s endurance is beyond his expectation: "what will this man do in the end?"


    "Bang!" Second lieutenant Deng also pointed out that he made a shooting position beside his head.


    "Well, there''s really no need to keep such people." Chen Xin shook his head and changed the topic: "if it''s lieutenant Deng, are you sure you can walk from downtown to Linshi in this weather?"


    In the face of this question, Lieutenant Deng thought for a moment before answering: "if we are prepared, everyone in our army can do this. In fact, we''ve been to the Northeast before, training naked in minus 20 or 30 degrees to exercise cold resistance.


    For example, the survival and March in the extremely cold environment of walking tens of kilometers in the field is also part of the training of special forces. Therefore, it is still possible to walk from the urban area to the city in this kind of environment.


    However, we must be prepared in advance to have enough assurance. If we cross these dozens of kilometers of mountain roads unprepared, we are likely to freeze to death.


    Especially in this dark environment without sunshine, once you lose your way, you will only freeze to death. "


    Hearing what Deng said, Chen Xin rubbed his chin and fell into meditation.

 Chapter 410

    Chen Xin''s going out this time, of course, did not mean to have a problem with the special forces protecting him. He wanted to express his attitude that he did not want to be restricted.


    Although it is not that there is no expression of willingness in this regard, the main thing is that Chen Xin really wants to go out and deal with some things.


    As Chen Xin gained the status of academician and built a scientific research base outside his refuge, the transaction between Chen Xin and the special police team of the Municipal Bureau could not go on.


    It''s not that Chen Xin is not willing to continue to provide vegetables and fruits for the SWAT team, but in this case, the deal between the SWAT team and Chen Xin has become very embarrassing.


    So Chen Xin went out this time to talk with the special police team about how to deal with this matter.


    Escorted by armored vehicles and special forces, Chen Xin and his party did not come to the Municipal Bureau, but to the municipal government.


    The difference of identity brings about the change of people''s identity.


    When Chen Xin was just an ordinary Internet writer, he only dealt with his friends, who were also ordinary people and had no contact with senior government officials.


    That is, after the disaster, with the transformation of the relationship between the old order and natural disasters and the improvement of Chen Xin''s own system, he gradually began to contact some people he could not contact.


    Now he is an academician of the most advanced science institute in Yanguo, and the identity of the people who deal with him is also rising.


    It turned out that Chen Xin came to the municipal government to see at most a few ordinary staff members, and the leaders in charge were rarely seen. But now it is a vice mayor who receives him.


    "I didn''t expect to see academician Chen in our city. I didn''t find academician Chen earlier. Your talent is a mistake in our work. Please don''t blame academician Chen!" After the vice mayor exchanged greetings and politeness with Chen Xin, he asked Chen Xin what he wanted to do: "I don''t know what academician Chen is doing here today? If there is anything that needs to be dealt with by the municipal government, we will do our best. "


    Chen Xin didn''t take the vice mayor''s politeness and flattery seriously, but only explained with a reserved smile: "before, I used to trade goods for vegetables and fruits with the special police team of the Municipal Bureau, which helped me a lot, and the special police team also helped me a lot.


    But now we are building a scientific research base, and then we will build large-scale planting greenhouses and study ecological agricultural technology. The output of this agricultural and sideline product will be greatly improved. In addition, changes in the situation and the material trade of the special police force will also be affected.


    So I want to ask if the municipal government can sign a new agreement with the research base to purchase the agricultural and sideline products produced by the research base. On the one hand, it can digest the output of the research base, and on the other hand, it can improve the quality of life of urban residents. "


    The question raised by Chen Xin made the vice mayor fall into thinking. This matter is big or small, but it is not small at all.


    Among the refuges in the urban area, there are underground farms. Although the output is difficult to meet the demand of vegetables and fruits in the whole urban area, it can still guarantee a certain output.


    However, this small amount of production certainly can not meet the needs of the whole city, and even it is difficult to simply meet the food needs of a shelter.


    Therefore, the distribution method adopted by the municipal government is to reward fresh fruits and vegetables and other agricultural and sideline products to individuals or collectives who have made outstanding contributions every month, so as to make the best use of the resources without causing any problems due to uneven distribution.


    But now Chen Xin says that his scientific research base will build large-scale planting greenhouses and study ecological agricultural technology, and there will be a batch of agricultural and sideline products, which will obviously affect the original material distribution plan of the municipal government.


    Therefore, the vice mayor must seriously consider how to respond.


    "Academician Chen, how many agricultural and sideline products can you produce?" After thinking about it, the vice mayor asked Chen Xin carefully.


    If it''s just a little output, it''s very easy for the urban area to digest it, as long as it continues to be used as a reward together with the original agricultural and sideline products. However, if the total amount of agricultural and sideline products produced by the research base is large, the problem will be embarrassing.


    After all, it''s just a research base. Even if the output of agricultural and sideline products is large, it can''t meet the needs of the whole city. But if the output is large, it will be cheap to continue as a reward, which will make the original reward system very embarrassing.


    "At present, because the construction of the planting greenhouse has not started, I am not very good to answer this question, but the planning area of the planting greenhouse is 12 hectares, which will be used to study the three-dimensional ecological agricultural planting technology. In terms of yield, there should be dozens of tons of agricultural and sideline products every month." Chen Xin is not very good at calculating this. After all, different fruits and vegetables have different yields, and three-dimensional planting will be adopted in the greenhouse. He has no idea how much yield he can achieve.


    Of course, the output is not small, but it is not much. Although tens of tons sounds like a lot, it is still not enough for a city. On average, each person may have enough to eat, but as before, it seems too much as a reward.


    "There''s a lot of production! If there are so many fruits and vegetables, it will be a great blessing for the urban residents! " No matter what you think in your heart, this kind of thing is always a good thing. Naturally, the vice mayor will enthusiastically agree.As for how to deal with the follow-up, he can only say to Chen Xin, "just how to deal with so many agricultural and sideline products? I need to have a meeting with the comrades of the relevant departments to discuss it before I come to a conclusion. Academician Chen, if you don''t think so, let''s first work out a general plan, and then we will determine the specific treatment plan after you harvest the fruits and vegetables?"


    "It''s OK. You can deal with it as you should, and I don''t know much about these things." Vice Mayor Chen Xinchong also politely said a few words before leaving.


    After leaving the city government, Lieutenant Deng on the armored vehicle suddenly asked Chen Xin curiously, "academician Chen, are not many dozens of tons of fruits and vegetables? Can''t the research base be digested internally after it is built? "


    "Ha ha, you don''t think there is only one greenhouse, do you?" Facing this problem, Chen Xinxiao has profound meaning.


    Although there is only one greenhouse planned now, Chen Xinzao planned to build a large-scale greenhouse before he went to Linshi. Now that the conditions are ripe, how can he build only one?


    Ignoring the confused second lieutenant Deng, Chen Xin said to the driver, "don''t hurry to go back first. I have to see a friend."

 Chapter 411

    In Li Yulong''s shelter, looking at Chen Xin and the special forces standing beside him, his eyes were full of envy and shock.


    For Chen Xin, Li Yulong certainly admired him very much. Especially when this last natural disaster came, Chen Xin''s various responses and the changes of the whole person after the disaster made Li Yulong treat Chen Xin with great admiration.


    It''s just that he never thought that Chen Xin could become an academician of Yanguo''s highest Academy of Sciences, and even have the close protection of special forces.


    This kind of treatment, usually can only be seen in the network novel, in reality, which one of these academicians is not the seniority, the author can have this treatment?


    "Little brother Chen, you are so powerful, academician title, special forces personal protection, card face! If there is anything I can do for you in the future, you must speak up! " Li Yulong compliments Chen Xin.


    As a businessman, he has a natural instinct and a unique family knowledge about what kind of people he should flatter, win over and adopt.


    However, for Chen Xin, these are just the things that have been heard almost quickly these days.


    And for Chen Xin, he regards Li Yulong as a brother and friend, and does not like the way he is now.


    "If you talk like that again, believe it or not?" Chen Xin shook his head and said to Li Yulong, "you are indispensable for good, and you are also indispensable for something. I regard you as my brother, so don''t play with me."


    Hearing what Chen Xin said, Li Yulong immediately laughed, but his face looked more natural: "Hey, this is not brother Chen. You''ve become so powerful all of a sudden. I can''t get used to it!"


    "Is there anything I can''t get used to, isn''t it the same as before?" Chen Xin said disapprovingly, but he also understood that he could not really get along with him as before.


    When I wrote novels in the past, I often wrote that some people are in high positions and want to get along with their friends just like in the past. Although they have maintained their past mood, with the change of their status, their friends can never go back to the past.


    The calculation of gains and losses of various interests is no longer as straightforward as it used to be.


    Originally, Chen Xin thought that this was only the plot in the novel, or only those who were really in a high position would express the feeling of being too high to be cold, but now he is going to have the same feeling.


    As a second-generation rich man, Li Yulong had the best family background among Chen Xin and his friends. In addition, his personality is not bad. Everyone is willing to make friends with him and treat him as a friend and brother. Although his status as a second-generation rich man does not flatter him, it still has some influence.


    But now, even Li Yulong, a second-generation rich man, has to curry favor with Chen Xin. In addition, the former vice mayor and other big people who were hard to see in the past have handled him carefully, which makes Chen Xin feel that as expected, after his identity has changed, not only the people he contacted have changed, but also other people''s attitudes towards him have changed greatly.


    Chen Xin said to Li Yulong, "I''ve come to see you for business."


    "Brother Chen, if you can do it, you will never refuse!" When Li Yulong saw Chen Xin''s zhengse, he took it seriously and looked at Chen Xin waiting for him to speak.


    "I''m building a research base now, and then there will be a 15 hectare greenhouse for ecological agriculture research. My plan is to use it to find ways to increase the yield of food, fruits and vegetables." Chen Xin introduced the situation to Li Yulong and let him know the general situation before he continued: "after that, there will be a lot of output in my side every month. I have talked with the municipal government before and they will purchase these outputs, but the municipal government has not made up its mind about how to allocate these outputs."


    "So we have a chance to step in?" Li Yulong''s eyes suddenly lit up, and the merchant''s intuition made him aware of the business opportunities.


    "No, no, if it''s just a step in, don''t bother. I''ll just share your output." Chen Xin raised a finger and shook it, with the same smile on his face. He said, "I want you to take over the distribution of the output of these fruits and vegetables. On the one hand, it''s for your care, on the other hand, it''s for the distribution of more output in the future."


    "More output? But... " Li Yulong was stunned for a moment, but he soon responded.


    Since Chen Xin can build a greenhouse, he can certainly build more greenhouses in the future. As long as there are more greenhouses, there will be a steady stream of food output.


    Now it may be just a little, not enough to meet the needs of all people, but what if there are more greenhouses?


    There will always be times when we can meet everyone''s needs.


    In this process, Li Yulong undertakes the distribution of these outputs. With the increase of the total output, he will be able to participate in the material supply of the whole city.


    This is undoubtedly a great opportunity for Li Yulong. Even before the disaster, such an opportunity can be met but not sought, or even not at all.For ordinary people, food, clothing, housing and transportation are the four most important things, of which food is the most important. Otherwise, there would be no saying that food is the most important thing for the people.


    And being able to control the food supply of a city, even if it is only a part of it, is enough to make Li Yulong grow into an important existence for the city, even surpassing his father.


    Originally, such an opportunity could not be turned to Li Yulong, but now Chen Xin has put such an opportunity in front of him.


    Next, it depends on whether he can grasp such an opportunity and grow up.


    "After brother Chen, you are my brother! What do you want me to do? " Li Yulong was excited and patted Chen Xin''s chest with a look of going through fire and water.


    However, Chen Xin shook his head and said to him, "how to do it is up to you to think about it. I''m just telling you about it. And it''s a test for you. I''ll win the material distribution work with my ability. Otherwise, even if I give you the opportunity, you will not be able to hold on to it in the future. "


    Hearing Chen Xin say so, although Li Yulong was a little disappointed, he nodded understandably.


    Anyway, he was educated by his father since childhood. He knows that business can only be done for a short time by relationship. Others can help you once, but not for a lifetime. Only his own strength is enough, can business be done for a long time.

 Chapter 412

    Chen Xin, who returns to his refuge, calms down here. The life inside the refuge is orderly, and the construction site outside is also orderly. It seems that everything has calmed down temporarily.


    However, Chen Xin did not have leisure, and even had the impulse to find something to do.


    As a new academician, although Chen Xin has not officially started his work, the research projects previously assigned to him still need to be dealt with by him. Although with his becoming an academician and after the state adjusted the cooperation mode with him, these research projects have become fewer, but they still take up part of Chen Xin''s time.


    In addition, Chen Xin also needs to establish some research topics for himself.


    This is also one of the things Chen Xin needs to do after he becomes an academician. After all, as an academician, he can''t only upgrade the research projects assigned to him by the state.


    Although the construction of the scientific research base has not been completed, and the research work can not be carried out immediately, it is still possible and necessary to determine the subject first.


    At present, Chen Xin has established four major research projects: ecological agriculture, geothermal heating, controllable nuclear fusion and military equipment research, which are also the main research projects after the completion of the research base.


    However, in these four projects, military equipment research does not have specific weapons or equipment types. Instead, Chen Xin will study whatever he makes. Therefore, it can only be regarded as a big topic, not a specific research.


    Just like the heavy machine armour and mobile barracks provided by Chen Xin for the protection of his special forces, if they are research topics, they can be divided into two completely different research topics and two research groups have been established.


    As for geothermal heating and controllable nuclear fusion, both of them are vital energy issues for the country. However, after Chen Xin handed over the relevant equipment and drawings to the country, he did not need to do much in this regard.


    The state has sent more professional researchers to take over the relevant research, and Chen Xin is also not required to do anything.


    After all, all he can do is to upgrade the equipment without considering the theoretical basis. As for the relevant theoretical research, it can only be handed over to others.


    As for ecological agriculture, it''s even more so. If you want to build an ecosystem that can self circulate, it''s not something that Chen Xin, who can''t even do water circulation in the refuge, can play. The knowledge involved is not even something that one can learn in his life.


    If we want to study the ecosystem, we must have a large group of people to work together.


    Although Chen Xin only wants to create a small self recycling ecosystem, rather than studying the whole ecosystem, it is still not a simple task.


    In addition, the construction of the ecological dome has not been completed, and the related work can not be carried out. This topic is just a topic, and even the relevant researchers are in the process of deployment and recruitment.


    So in a short time, Chen Xin really didn''t know what he could do or what he wanted to do.


    Continue to upgrade your equipment and upgrade the nano armor and power armor?


    Chen Xin shakes his head and gives up the idea. Now he has enough defense, output and mobility. With the existence of nano war armor, he can fly away and fight crime like the iron man in the movie.


    Although there is no occasion for Chen Xin to become a superhero, he doesn''t want to do the same thing as underwear.


    What''s more, no matter how powerful a person''s force is, no enemy can kill a dragon.


    What''s the big difference between killing an enemy with a bullet and killing him with a missile?


    After serious consideration, Chen Xin shakes his head and gives up the idea of upgrading his equipment in a short time. Although he plans to build something like Kodak or Titan to play with, it''s not now.


    However, his own equipment does not need to be improved, but the equipment of the army is not necessarily. Moreover, for Chen Xin, what an army can upgrade is not only the equipment, but also the soldiers themselves.


    "Lieutenant Deng, I want to know, as a special forces soldier, what do you think of the human body reconstruction?" While walking on the construction site, Chen Xin inquired about the second lieutenant Deng who was following him.


    "Human transformation? It''s evil, isn''t it? " Second lieutenant Deng doesn''t know much about this, but in the past, the setting of evil scientists in movies and TV programs for human body reconstruction had some influence on him. Naturally, he felt that this kind of thing was not very good.


    However, Chen Xin does not think so, and this is not the answer he wants.


    "The chief sergeant in the halo series knows? Want to be as strong as him? " Chen Xin asked in a different way.


    "Chief Sergeant? Spartan fighters? Academician Chen, can you do that? " Second lieutenant Deng is young, even younger than Chen Xin. Naturally, he still knows about this fire science fiction game: "but don''t Spartan soldiers want to transform from childhood? Academician Chen, are you... "


    "These are not for you to think about. Answer my question. Do you want to have that kind of power?" Chen Xin didn''t ignore Deng''s groundless Association, as long as he answered his own questions.Asked by Chen Xin, Lieutenant Deng seriously thought about it and replied, "if I can, of course I want to have such a powerful force, but if it is based on the transformation of children''s body, it''s too cruel."


    "Spartan soldiers'' technology is really cruel, and the mortality and cost are too high. If I come, I will choose adults who are willing to accept the transformation, and reduce the risk and cost of surgery." Chen Xin shook his head, obviously for the game Spartan transformation technology is not too optimistic.


    In fact, it''s true. Although the Spartans in the halo series are really strong, especially the sergeant, who is so strong that he can''t fight against heaven and earth, it seems that the sergeant is not good enough compared with the fierce men in other science fiction works.


    In terms of physical fitness alone, the star fighters who can live for hundreds or even thousands of years in Warhammer 40K series are undoubtedly much stronger than sergeants.


    Thinking of this, Chen Xin suddenly recalled the idea that came out of his mind before, so he asked second lieutenant Deng, "if you can get more powerful strength and physique, but the cost may be great changes in your body, or even some animal characteristics. Do you think this is acceptable?"


    "Animal characteristics? Body changes? What are the specific characteristics and changes? Academician Chen, can you talk about it in detail? " Second lieutenant Deng did not refuse at the first time, but wanted to make a careful judgment. If the impact is not significant, he does not think it is unacceptable.

 Chapter 413

    If you are familiar with science fiction and like to play games, you should not be unfamiliar with the name of Warhammer.


    This board game, created by a British desktop game company, is famous for its grand background and complicated settings, and has a considerable degree of fans all over the world.


    The whole series of Warhammer is divided into middle ages, 30K times and 40K times, among which the middle ages is a fantasy background, which is quite different from the space opera like sci-fi settings of 30K times and 40K times.


    As an Internet writer, Chen Xin is also a Warhammer fan, but his main favorite is 30K and 40K science fiction series.


    In these two series, human civilization has flourished to an incredible level. The Empire has a territory all over the galaxy, with a population of trillions. It has more fleets than stars. It also has a huge Legion whose death list can only record numbers. It is fighting endlessly with countless enemies who can destroy the whole galaxy.


    In the whole human Empire camp, the most famous and characteristic is undoubtedly the Star Warrior.


    The 18 star warrior battle groups with their own characteristics and the individual combat power comparable to the demigod of the human world undoubtedly make the Star Warrior the absolute protagonist of the Warhammer series.


    Each of the 18 Star Wars regiments has its own unique shape and characteristics. Chen Xin''s favorite is undoubtedly the space wolf whose prototype is from the Vikings.


    Their primitive and crude temperament, Viking style and wolf like fighting style make this group unique even among the 18 Star Wars.


    In the background setting of space wolves, the most distinctive and legendary is their wolf genes.


    This unique gene obtained by oral administration of drugs will make the soldiers of the space wolf change dramatically from spirit to body, increase their body size by 80%, reshape most of their bones, grow exuberant hair and huge wolf teeth, and even become "werewolves".


    It''s not only physical changes, but also barbarism and bloodlust of soldiers who have acquired wolf sex gene. Although they can rely on training and rational suppression at ordinary times, these instinctive characteristics will appear again when they fight against the huge pressure on the battlefield.


    What Chen Xin wants to do is to create a realistic version of the space wolf.


    They are human demigods in the true sense. Their physical strength alone is enough to fight against the existence of an army. What''s more, they are known as a Star Warrior team, which is enough to suppress the rebellion of a planet.


    Of course, because of the background setting, the transformation technology of star fighters has a certain degree of mystery, including their birth, manufacturing, growth and fighting process, which are affected by mysterious elements, which is almost impossible to replicate in the real world.


    What''s more important is the setting of Warhammer 30K and 40K series, which is tens of thousands of years in the future. Human science and technology has developed to an incredible stage. It''s very difficult to truly recreate the Star Warrior or space wolf in the real world.


    Even if Chen Xin has a system to help, it''s hard to do so. At least in terms of equipment, Chen Xin can''t provide a complete set of equipment for every reformed soldier, let alone have hundreds of years to wait for them to grow up.


    But if it''s only a certain degree of reproduction, for example, through the implantation of wolf sex gene, it''s easy for ordinary soldiers to grow rapidly and have strong combat effectiveness.


    This is exactly what Chen Xin wants to do.


    Genetic modification technology and the production of wolf sex genes are not impossible for Chen Xin.


    Although the upgrade function of the system can not be used by people and other animals, and even plants are not within the scope of the system''s influence, it is still possible for the system to manufacture an instrument that can be genetically modified or gene compiled.


    Chen Xin only needs to make the relevant instruments, and then use the instruments to make the wolf genes and the gene seeds needed for the Star Warrior''s 19 surgical transformations, so that he can reproduce the Star Warrior in reality, which is comparable to the existence of a demigod in the human world.


    You know, even the most common star fighter is taller than little giant Yao Ming and stronger than Shaquille O''Neal.


    Just imagine, a group of soldiers who are more than two meters tall, bulky and strong, just like wolverine, appear on the battlefield. They are also equipped with powerful weapons and armor. How terrible should they be?


    Some people may think that in the current environment, where do we need such powerful soldiers? All countries are too busy to fight. Who will launch a war at this time? Do you need such a strong soldier?


    To answer this question, Chen Xin just wants to say that there is no sword in his hand, and there is no sword.


    Moreover, in the current environment, perhaps all countries are really worried about themselves, but the more this happens, the more careful they need to be, because there are always people who will jump over the wall because they can''t survive.Ordinary small country is not terrible, but the bear in the north of Yan country is not a vegetarian.


    As the same five hooligans, there was more than one war between them in history? The country sandwiched between the two countries was originally the territory of Yan country. It was abruptly split by the bear and became a so-called country!


    Perhaps because of the changes of the times, the two countries have been close as brothers, and now they have friendly relations. But in the face of a country''s life and death, any idea of putting hope on the enemy''s kindness is killing its own people.


    And there is also a very important factor, that is, star fighters exist for the purpose of fighting in the space environment. Their physical quality is very strong enough to fight against any bad environment.


    In particular, the space wolves live on a planet where the sea is frozen for half of a year. The powerful power given by wolf sex genes even enables them to walk through the ice sheet thousands of miles away.


    In today''s situation, it is excellent to have a fighting force that can fight against extreme environment, even if it is not used for fighting, but for disaster relief. After all, our army has always had the tradition of rushing to the front line of disaster relief.


    After serious consideration, Chen Xin made sure that he had no problem with his ideas. Then he sorted out his ideas and decided to make space wolf his next task, and thought about how to start.

 Chapter 414

    "Does the country keep animal gene samples or live embryos before the disaster?" While fiddling with a prototype of the project, Chen Xin asked a researcher nearby.


    This time, this researcher came to send him prototypes of research projects that need to be upgraded. Although the total number of projects allocated to Chen Xin has decreased a lot, many prototypes of projects will still be sent to Chen Xin every once in a while, so he needs to upgrade them.


    After hearing Chen Xin''s question, the researcher recalled it and then replied, "before the disaster, the state has established seed banks in the Kunlun Mountains and the Himalayas, where a large number of plant seeds, animal embryos and gene samples are preserved. Academician Chen, do you need this?"


    Chen Xin was reminded by this researcher''s reply. He had heard about this before. The state has frozen a large number of plant seeds and animal embryos in the seed banks of Kunlun Mountains and Himalayas as the basis for rebuilding the earth''s ecological environment after the end of the world.


    If there is anything that Chen Xin needs now, these two places are undoubtedly the most likely ones.


    After asking about this, Chen Xin nodded and said to the researchers, "can the gene samples and living embryos in these two seed banks be applied for research? I''m going to do some research on genetic modification. I need wolf gene samples and live embryos. "


    "Genetic modification research? Academician Chen, what kind of research are you going to do? " When the researchers heard Chen Xin say this, they immediately felt curious.


    After all, Chen Xin was basically dealing with machines before, and had no contact with biological research. Now, although Chen Xin is preparing to start research in the field of ecological agriculture, it can really use genetic transformation technology, why does Chen Xin need wolf gene samples?


    "I intend to cultivate a kind of wolf that can adapt to the current climate and environment to help human beings survive better in the current environment." Chen Xin did not tell the researcher his ultimate goal.


    Chen Xin decided to talk about the cultivation of star fighters himself. If the information is transmitted through ordinary scientific researchers, it will be bad if the information is leaked.


    "Academician Chen! Even if other people have this idea, they can''t put it into practice. Academician Chen, you are so powerful! If we can cultivate a group of animals that can adapt to the present environment, it will play a big role! " Researchers need only think a little to understand the prospects of Chen Xin''s ideas.


    Apart from other things, even if these animals have no other uses, it is good to kill and eat meat and get fur.


    Not to mention that Chen Xin wants to cultivate wolves and close relatives of dogs. If he cultivates well, he can be a good helper for human beings.


    "So can these embryos and samples be applied for?" Chen Xin didn''t care about the flattery of the researchers, but only about whether he could get gene samples and live embryos.


    After all, no matter how powerful he is and how powerful the system upgrade function is, there is no way to create something out of nothing. We must have gene samples and living embryos for the transformation to make the whole transformation work.


    And the most important thing is that this is just the beginning. After he has bred new kinds of wolves, he still needs to extract the so-called "wolf genes" from these wolves for his real purpose - the transformation of space wolf soldiers.


    Of course, in the future, we can''t call them star fighters and space wolves. After all, they are only ground troops, and they can''t reach the original level of galloping over the sea of stars and hunting in the sky.


    "If it is academician Chen, you should be ok? I don''t know about this. The seed bank is for the preservation of species samples and the restoration of ecology after the end of the day. If it is for the restoration of the natural environment, it may take hundreds or thousands of years before it is put into use. " The researcher touched his chin, thought about it, and said to Chen Xin, "academician Chen, if you apply in the name of research, you should be able to apply. After all, you have to carry out ecological environment research, and you should apply for a batch of gene samples."


    "Thank you for your advice. I''ll think it over." Chen Xin nodded, and he had already made plans in his heart.


    After upgrading the prototype of the project and letting the researchers take it away, Chen Xin went to the temporary military camp of the special forces, found the commander and explained his intention. With their communication equipment, he sent his application for wolf gene samples and live embryos, along with the genetic transformation plan conceived by Chen Xin.


    After passing on the information, Chen Xin also talked with the commander about the idea of genetic modification to make super soldiers.


    "Can this kind of genetic modification really be done? Will there be any bad consequences? " The commander''s first thought was whether such genetic modification would have side effects.


    Chen Xin shook his head. He was very confident in his own technology, or the ability to upgrade the system: "there are no bad consequences, but according to my imagination, the soldiers after the transformation can reach 2.3-2.5 meters in height, weigh more than 200 kg, and have a single arm of more than half a ton of strike power.


    It may be accompanied by thick hair, abnormal growth of canine teeth, a certain degree of violence and bloodthirsty tendency. If you mean these bad consequences, some of them can be controlled and adjusted, and some of them can''t"Which ones are controllable?" The commander asked with concern, if you just grow tall and strong, these are actually very acceptable, but violence and bloodthirsty are not the characteristics that a soldier should have, at least not in Yanguo.


    As for the commander''s question, Chen Xin had expected, which is also a reasonable question. He replied with a smile: "the growth of height and weight is inevitable, which is also the effect of genetic transformation. As for thick hair and abnormal growth of canine teeth, it''s not a big problem. Violence and bloodlust are controllable and adjustable.


    However, I personally think that it is more conducive to the exertion of combat effectiveness to appropriately retain certain wildness. Although it may bring some adverse effects, it is generally controllable. "


    "Sounds good. What''s a man with a little hair?" The commander obviously didn''t think that thick hair on a man was a side effect. It was just a matter of using razors more frequently in the future: "but this violent bloodthirsty is very dangerous. Our soldiers can''t do this."


    Chen Xin can''t deny this, just nodded and said: "it''s not difficult to get rid of it, and it can be controlled by training the day after tomorrow."

 Chapter 415

    Genetic modification is a controversial thing, which involves moral, ethical and other issues enough to hinder anyone who wants to study it.


    Even with unswerving determination to study it, some people will still ask you: "if a person changes his genes, can he still be called a person?"


    Similar conceptual conflicts and disputes are common in all kinds of sci-fi works. At any time, there will always be a group of so-called human supremacists clamoring for "a clean world for the sake of blue".


    Even in order to prevent the so-called crime of "tarnishing human genes", they will concoct more appalling and more anti-human evils, and glorify it as necessary sacrifice.


    ¡°¡­¡­ But what can we really call people? How can a man be a man? " Chen Xin asks Qin LAN the same question.


    "Well, isn''t human being human? The reason why human beings are human beings is that we are intelligent, intelligent and thoughtful? " Qin LAN has seen some sci-fi works under the influence of Chen Xin before, but she can''t answer the question he asked.


    However, this answer is obviously not comprehensive enough, at least not completely correct.


    "The reason why people are human is because we have wisdom and thought, but is wisdom and thought innate? The answer is not necessarily Chen Xin is really like a scholar, sitting in front of Qin LAN and talking: "if a baby grows up in human society, he can naturally have the wisdom and thought that can be called a person, but if a baby is far away from human society since childhood, or even raised by wild animals, he can''t have what a person should have The wisdom and thought of the people. "


    For Chen Xin''s this view, Qin LAN did not refute, but agreed with the nod.


    In 1920, in a small town named midnapol in the northeast of Calcutta, India, two girls raised by wolves, known as wolf children, were found and caused a sensation.


    The oldest of the two girls was about seven or eight years old, and the youngest was about two years old. The two little girls were sent to the orphanage in midnapol to raise them, and they were named as Kamala and Amara. The next year Amara died, and Kamala lived until 1929.


    Through this event, people have come to a conclusion that if wolf children are not born with congenital defects, then this example shows that human knowledge and talent are not innate, upright walking and speech are not innate instincts, all of which are the products of acquired social practice and labor.


    "So the reason why people can be called human beings and have wisdom and ideas is because of the existence of the whole human civilization and society. If we lose these, we are not much different from wild animals." According to Chen Xin, the reason why human beings are called human beings comes from thought and soul, not from body: "if we only look at them from species, human beings are Homo sapiens. They are only one of the species of Mammalia, Mammalia, primates and ape.


    Even under the category of Hominidae, subfamily Hominidae, there are 16 other species listed with Homo sapiens. Although they are extinct, they can also be called humans from a biological point of view.


    So simply from the perspective of biological classification, there is no essential difference between human beings and other animals. The so-called supremacy of human beings is just the arrogance of human beings. "


    "But even if there is no essential difference between human beings and animals, human beings also belong to animals. Isn''t genetic transformation still polluting the purity of human genes?" I don''t know when Mo Qingyan, who appeared on one side, suddenly put in a word: "and put aside other problems, ah Xin, you use wolf''s genes to transform human beings. Are you a wolf or a human? Don''t do such things that are against morality and ethics? Before the disaster, the state just issued a crime of illegal gene editing? Ah Xin, have you violated the law? "


    "That is a new provision added to Article 336 of the criminal law, which regards it as a crime to implant human or animal embryos edited or cloned by genes into human or animal bodies, or to implant animal embryos edited or cloned by genes into human bodies." Because of the need to do relevant genetic transformation research, Chen Xin also consulted the relevant legal provisions: "embryo implantation is a crime, pure gene research, not a crime."


    "But even if it''s not illegal, it''s also against morality! Human genes are the perfect product of evolution. How can they be modified at will? " Because of her professional habits, Qin LAN didn''t like Chen Xin''s attitude that I could do without legal provisions.


    "Morality really needs to be obeyed, but if there is ignorance in morality itself, do we still need to obey social morality? In feudal times, women''s lack of talent was virtue, which was the social morality at that time. But do we still need to abide by this kind of thing now? Society is developing and progressing, and so is morality. " Chen Xin painstakingly explains to Qin LAN and Mo Qingyan, trying to persuade them.


    This is the two of them. If they had changed to other people, Chen Xin would have been impatient. How could he have such good patience to explain slowly.


    "Even if social morality needs continuous progress and development, this is not the reason to modify human genes at will, is it?" Mo Qingyan calms Qin LAN, who is a little excited, turns to Chen Xin and asks, "the human body is a perfect masterpiece of natural evolution. Even if there is something inappropriate, can''t we wait for human self evolution? Why do we have to take such radical measures as genetic modification? ""Is the human body perfect? Hahaha, long Niang, I''m afraid you''ve read too many novels. Do you really think that human beings are born with Tao, and monsters have to become adults before they can practice? " Hearing this, Chen Xinxiao seemed to have a stomachache. Until Mo Qingyan twisted him discontentedly, he stopped laughing and continued to explain: "the reason why human beings are like this is just the result of continuous compromise to the natural environment, because human evolution is not the body, but the brain. From the perspective of biological evolution, human body is actually very cumbersome and bloated It''s swollen.


    And it''s not only our bodies, but also our genes. Countless redundant chains are full of our genes. Some of them come from the remnants of our evolution from the sea to the land in the past, and some of them are just emergency mechanisms evolved to adapt to the environment of a special period, but all of these things remain in our genes It is miscellaneous and useless.


    It doesn''t matter if it''s just extra garbage, but these complex and complicated genes are mutating all the time, and even self collapse, forming life eroding tumors in the body.


    To remove the sacredness of human beings, from the point of view of the strength and quality of biological structure, all human organs are not the best, or even a lot of bad ones.


    Overlapping organ functions, wasteful neural channels, winding like the most complex labyrinth, but not as good as straight-line blood vessels and neural networks, as well as all kinds of abandoned and useless information from the beginning of genes


    If human beings are regarded as an engineering creation, then this creation can only continue to work through various coincidences and external factors.


    Therefore, with the development of human science and technology and the progress of medicine and biology, it is necessary to optimize and transform genes

 Chapter 416

    Although Chen Xin''s reason is very good, but in the end, they still can''t convince Qin LAN and Mo Qingyan.


    Of course, they also did not persuade Chen Xin to give up the idea of genetic transformation.


    The discussion between the three nearly broke up in a bad mood, but Chen Xin finally chose to give in and promised that he would start with simple gene strengthening and adjustment, and create the adjusters in the series of GAODA, instead of starting to build star fighters.


    Although there is no essential difference between the two, it is much easier to say to the extent that ordinary people can accept it.


    And for Chen Xin, manufacturing regulators are also much simpler.


    The reason why the star fighters are powerful and have a strong physique beyond imagination is that they have to undergo a total of 19 surgical transformations for 10 years, and implant various strengthening organs for themselves, so that they can grow into super fighters with a height of 2.5 meters and a weight of more than 200 kg.


    And after that, they need to go through 100 years of recruit training, inherit the combat memory from the gene precipitation and inheritance of 10000 years, in order to become a real sense of interstellar fighters, put on the power armor which also inherited hundreds or even thousands of years, and become the most powerful force of the Empire and the demigod of the world galloping across the galaxy.


    Although the adjusters of the Gundam series started genetic transformation from embryos in the original work, it is much easier for Chen Xin to make the gene enhancer mentioned in the ancient science fiction and directly inject it to realize gene optimization and adjustment than to really copy the Star Warrior.


    After thinking about it this way, Chen Xin feels that he really doesn''t need to step too far.


    With Chen Xin''s promise, Qin LAN and Mo Qingyan don''t say anything more. They just have reservations about it.


    It''s just that Chen Xin of Qin LAN and Mo Qingyan is easy to handle, but it''s not so easy for the country to push this matter forward.


    Knowing that Chen Xin wanted to carry out genetic research, the state''s attitude was originally very supportive. However, the genetic transformation plan proposed by Chen Xin to create super soldiers was opposed by many people.


    After repeated meetings, debates and even quarrels, the state sent a moral and ethical review team composed of experts in relevant fields to Chen Xin to review his research topic.


    Instead of rejecting this, Chen Xin explained to them what he wanted to do, the relevant ideas and the means to achieve it.


    "In other words, academician Chen, the genetic modification experiment you are going to carry out is not based on gene editing of embryos?" After listening to Chen Xin''s explanation, an expert in the review group asked Chen Xin this question with a slightly loose expression on his face.


    To this question, Chen Xin did not nod his head directly in order to pass the examination. Instead, he explained: "in my expectation, the transformation of wolves can only be achieved through genetic adjustment of embryos. However, considering the growth time of a normal human, I think it is a faster way to directly transform adult individuals."


    "Gene editing itself is not illegal, the state is also carrying out research in related fields, and the restrictions in related fields are not as strict as expected." The expert nodded slightly. Although he didn''t say anything clearly, his attitude showed kindness.


    However, the expert was kind-hearted, while the other expert was very malicious and showed a very disgusting attitude towards Chen Xin.


    "Have you considered the consequences of human genetic modification? Polluting the gene pool of human beings is a violation of social ethics and a threat to national security! " As soon as the expert opened his mouth, his hat fell off.


    Chen Xin just looked at the expert and said, "you can accept cyberpunk style whole body reconstruction. Why are you so opposed to simple gene enhancement? Anthropocentrism? Fundamentalism? If scientists hold such an idea, human civilization will not progress. "


    "You Chen Xin''s words are very hard to hear. He almost points to the expert''s nose and scolds people for being archaic, which naturally annoys the other party.


    But the expert was held down by the leader of the review team next to him.


    "Academician Chen Xin, the main purpose of our review is to examine whether your research conforms to the moral and ethical standards. Scientific researchers should respect life, abide by the rules, protect a pure land in the field of cutting-edge science and technology, and make innovative achievements better benefit mankind." The leader of the review group stressed to Chen Xin that his attitude is not bad, nor good: "although the development of science and technology has brought tremendous changes to society, and now is also a special period and special environment, scientific research still must abide by the ethical norms of scientific research, and the bottom line of scientific research ethics can not be touched or challenged.


    Your research is not about gene editing of embryos, but even so, will individuals who have completed the genetic modification pass on the modified genes to the next generation? Will this inheritance cause side effects or unpredictable consequences? Are these genetically modified people still human? Or should we call them new humans?


    Academician Chen Xin, you are very young and have a lot of ideas. This is the vitality that we old guys don''t have. But I think you should be more careful. Do you have a comprehensive consideration of these problems? "The remarks of the leader of the review group softened Chen Xin''s original tense attitude and readjusted his mood. Then he said: "genetic transformation itself is the optimization and promotion of human genes. This kind of change directly affects adult individuals and will indeed be passed on to the next generation.


    As for whether there will be side effects or unforeseen consequences, I can''t give you a positive answer, because less than 2% of the genes in the human body encode proteins, and we can''t confirm the role of the remaining 98%.


    Although the genetic transformation I want to carry out will only adjust the 2%, I can guarantee that there will be no problems within at least three generations, but whether the transformation will conflict with the original human genes or produce new mutations will require long-term experiments and observations.


    As for the problem of new and old humans, there is no problem at all, because everyone can accept genetic modification to become new humans. "


    At this point, Chen Xin deliberately pauses, looks at the expert who was disgusted with him before, and then continues: "of course, if someone thinks that human genes are sacred and inviolable, and any modification is blasphemous, they can also choose to retain the original genes to maintain the purity of human gene pool."

 Chapter 417

    The ethics review group did not immediately come to a conclusion. After all, what Chen Xin said is only conceptual. When the actual research is carried out, many things will be different from the original idea.


    In particular, it involves human body modification and gene editing, which will have an extremely huge impact. It is not up to the members of the review group to be cautious.


    However, the people in the review group are still carefully discussing and reviewing Chen Xin''s research, while the people in the military have taken the lead in finding Chen Xin and learning from him about the super soldier transformation plan he put forward before.


    The military also understands the problems and effects of human body modification and gene editing, but the super soldiers described by Chen Xin still make the military have some exploration and curiosity.


    After all, isn''t the man in the movie who wears the federal flag and a shield to kill the World War II also a genetically modified man?


    If we can get all the soldiers No, it''s tempting for the military to be able to reach the human limit of combat capability even if it''s just a division or a special combat brigade.


    Of course, the premise for the military to support Chen Xin''s research is that the research will not bring harm and adverse consequences.


    "As far as the technology I have at present is concerned, the realization of the combat effectiveness of the captain in the movie will not cause any adverse effect." Chen Xin still took the combat power standard familiar to him when he wrote his fellow novels as an example and explained to the Commissioner sent by the military: "in fact, this degree of genetic transformation can not be called transformation strictly. It can only be regarded as strengthening, so that human genes show the optimal state. This strengthening is in fact the same as transgenic soybean can enhance the ability of disease resistance and insect damage.


    As for whether there will be any adverse effects, I can only say that there will be no problems within three generations of heredity and within 50 years of individual survival. More follow-up effects need long-term experimental observation to draw more conclusions. "


    In fact, it is easy for Chen Xin to achieve gene enhancement without side effects with the black technology displayed by system upgrading. But at this moment, no one will believe him if he says so.


    So Chen Xin said a more conservative answer.


    "Won''t there be any problem within three generations?" Even for the military, the first consideration is genetics and sequelae.


    "Well, this result is calculated. As for the consequences after three generations, I don''t have a supercomputer to calculate the possible consequences." It''s true that supercomputers can be used for this kind of calculation. Chen Xin is not asking for supercomputers. He is just expounding a fact.


    Moreover, after the completion of the scientific research base, it is sure to be equipped with supercomputers.


    "Three generations This is about 50-70 years at least! " The Commissioner of the military made a little calculation of the time, and he realized that Chen Xin had said that the 50 year survival of an individual was actually consistent with the genetic time.


    "This time is not long, and the probability of real problems is lower than the probability of human genetic variation. In short, the probability of gene enhancement problems is far lower than the probability of a normal person getting cancer." Chen Xin gives a typical example of comparison, but he also understands that there is not much comparability.


    Although the probability of cancer is very high, and even everyone has the probability of getting cancer, but cancer is only a disease, and it is not infectious, and there is only one death at most, with limited impact.


    But if there is something wrong with the gene reinforcement, it is likely to affect all the individuals who have received the gene reinforcement, even their offspring.


    We can''t be too careful on this issue.


    The military Commissioner does not have the right to make decisions, and he only records all the information after learning from Chen Xin for the use of inquiry and discussion.


    Therefore, after asking about gene enhancement, the military Commissioner also asked about the problem mentioned in Chen Xin''s previous plan of obtaining enhanced genes of wolves through genetic modification to create more powerful super soldiers.


    "Academician Chen, how did you come up with the idea of using wolf genes to transform people? This is not a simple ethical issue, is it? It''s not nice to say. It''s a cross between man and animal! " The military Commissioner''s words have been very heavy. After all, it is individuals who will reject the transformation of people into beasts.


    However, for this problem, Chen Xin just touched his chin, then took out his notebook, opened a piece of information and showed it to the military commissioner.


    This is the background setting and related information of the space wolf in Warhammer 40K, which is also the source of inspiration for Chen Xin''s whole transformation plan.


    "Is this the game setting? Academician Chen, is that your inspiration? But the so-called Star Warrior transformation surgery above all 19 procedures are implanted with 19 artificial organs, making an ordinary man into Superman. Can it really be done? " The military Commissioner did not have any idea because Chen Xin came up with a game setting. Instead, he seriously evaluated the information and judged the impact of the transformation of star fighters."If it''s just reconstructive surgery, I can say there''s no problem." Chen Xin really dares to make this guarantee, because it''s not difficult to realize the technology related to the transformation of star fighters.


    What''s really difficult is the cultivation of artificial organs, which is the root of star fighters in Warhammer 40K - gene seeds.


    "The artificial organ No wonder academician Chen, you need wolf gene samples and live embryos, and you need to do human genetic transformation! " The military commissioner has understood Chen Xin''s meaning, showing a sudden expression.


    Chen Xin nodded for sure, pointed to a picture of a star fighter on the computer and explained to the military Commissioner: "through the genetic modification of wolves, we can make gene seeds to cultivate artificial organs, then cultivate artificial organs from the gene seeds, and then implant the artificial organs into the modified human body through surgery.


    Technically speaking, the genes of the human body will not be affected in the whole process, because the modification operation does not achieve the enhancement of the star fighter by modifying the genes, but affects the work of the original natural organs of the human body through the implanted artificial organs, so as to achieve the enhancement of the star fighter. Theoretically speaking, the genes of the human body will not be affected.


    And that''s why, in the game settings, it takes a full 10 years to complete all 19 Star Warrior transformation operations, because this is not a mutation caused by gene compilation, but a secondary development under the influence of artificial organs. "

 Chapter 418

    Despite Chen Xin''s patient and detailed explanation, neither the ethics review team nor the military commissioner was convinced by him.


    After a rigorous investigation and evaluation, the ethics investigation team only passed Chen Xin''s application for genetically modified experiments on wolves, while the research on human genes was rejected and banned.


    The military did not support Chen Xin in this matter. Although they were also very greedy for Chen Xin''s powerful fighting power, they did not choose to support Chen Xin''s research on genetic transformation. Instead, they persuaded him to focus on the research projects that were tangible and would not cause any adverse consequences.


    Even the military has made it clear to Chen Xin that if Chen Xin wants to build the Titan, Gundam, space carrier and battle goblin snow wind in the game, the military will give full support to Chen Xin as long as he can make them.


    Obviously, since Chen Xin made exoskeletons and power armor, which were originally from science fiction works, the military has done a lot of research on the design of some science fiction works, and evaluated which things Chen Xin could make and which are good for the military.


    If it was before, Chen Xin might be very interested in it. After all, Gundam, Titan and space carrier are also very attractive to him.


    But now Chen Xin is in a depressed mood. Even if he receives an express from the military Commissioner, he is still in a little bit of a lack of interest. He just agrees that he will try to make Titan.


    This is the end of the dust. No matter how dissatisfied and depressed Chen Xin is, he can''t force himself to do research in private.


    In the final analysis, although he wants to do research and transformation in this field, there is a bottom line in the end. Without legal permission, he will not do it secretly.


    Although in terms of Chen Xin''s ability, even if he really secretly studies, others can''t help him. After all, when something happens, he may be a real star fighter.


    It''s just that although he won''t do things, Chen Xinli is still very depressed.


    His depression did not come from other people to prevent him from doing genetic transformation research, but from why these people would be so resistant to genetic transformation.


    Whether the review team or the military Commissioner, they prevented Chen Xin from carrying out the research on genetic transformation because they were responsible for the matter, not because of their personal feelings. Therefore, Chen Xin would not have any opinions on this.


    However, in the process of examination, Chen Xin felt that they were too conservative and conservative because of their uneasiness and resistance to genetic transformation.


    In a depressed mood, Chen Xin of course wants to have a chat with someone, but Qin LAN and Mo Qingyan have expressed their resistance to this before, and he is not easy to talk with them.


    After thinking about it, Chen Xin found his father and talked about it with him. He wanted to listen to the elder''s advice.


    After listening to his son''s complaints, Chen Xin''s father did not directly express his views on the matter of genetic transformation, but asked Chen Xin, "how many years do you think your own technology is ahead of the current technology? Can you do better than everyone else? "


    "I haven''t done this research before, but if you give me a chance to start my research, I''m sure I''ll be 50-100 years ahead of others! I can really do better than them Chen Xin is full of confidence in this matter, although the confidence comes more from the unspeakable system.


    However, after hearing Chen Xin''s words, Chen Xin''s father shook his head and said to Chen Xin, "don''t be so rash and impetuous. Since you are better than everyone else, why don''t you wait for others, or just pull them, and then do what you want to do when everyone reaches a level?


    As the old saying goes, the rafters are rotten first. If you are too strong alone, it will make you suffer unnecessary pressure. You are half a step ahead of others. You are a genius, but you are one or even more steps ahead of others. You can''t see the shadow of others. We will be afraid of you. "


    Chen Xin''s father did not comment on whether the research Chen Xin wanted to do was good or bad. Instead, he advised his son from another angle not to behave beyond ordinary people''s cognition.


    A few years ago, Chen Xin might not have been able to listen to this. He thought that keeping a low profile was just a lack of ability, or he thought I had the ability to hide. But now that he is in his early 30s, he has already passed the age of youth. He can still listen to his father''s suggestions.


    "Dad, you think I''ve gone too far, so they''re afraid No, it should be said to prevent me from taking off? " Chen Xin thought about his father''s words and suddenly changed his mind.


    "It''s a very dangerous thing. You ask two people to do it. You know the ability of one of them. Although he is not very capable, at least you know the consequences even if he can''t do it." Chen Xin''s father looked at his son, his eyes seemed to be gratified, and gave Chen Xin an example: "but although you know that he is very powerful and powerful, you don''t know how strong his ability is, and you don''t know what the consequences will be if he does it badly.At this time, are you willing to trust the first person and let him do things, or are you willing to trust the second person and let him play freely? "


    The example of Chen Xin''s father made Chen Xin take a breath. He reflected that he was acting too hastily in some things.


    Wood show in the forest wind will destroy it, although this is not necessarily right, but there is his truth, he can perform better than others, but too good, for mediocre people, is undoubtedly a kind of oppression and threat.


    Although the vast majority of people will not have any bad ideas because others are too good, but a certain degree of fear and preparedness is everyone may have.


    "I see, Dad." Chen Xinchong''s father nodded and understood what his father wanted to tell him. After that, Chen felt much better.


    And this calm down, Chen Xin also began to reflect on himself, some of his previous performance is indeed a little floating, or urgent.


    In the past, whether it is exoskeleton, isotope thermoelectric battery or geothermal power generation, these are technologies that ordinary people can understand and accept, and the state is also researching. Even controllable nuclear fusion reactor is a technology that has not been realized, but at least has mastered the principle and can be successful.


    However, genetic transformation is too advanced and sensitive. Chen Xin knows that he has the ability to control it, but others may not be able to understand it.

 Chapter 419

    After readjusting his mood, Chen Xin rearranged his ideas and plans.


    Since it''s too early for human genetic modification, this plan can only be shelved for the time being, waiting for the right time in the future.


    However, although the human genetic transformation plan has been shelved, the transformation and cultivation of wolves can continue in the future. It is a very promising research to cultivate large and cold resistant wolves as new domestic animals in the current environment, and the state is also very optimistic about it.


    Without Chen Xin''s human genetic transformation plan, it is believed that the transformation and cultivation of wolves alone will surely get strong support from the state.


    Fortunately, it''s not bad now. The ethics review team has passed the review of the experiment before. After the construction of the research base is completed, relevant wolf gene samples and live embryos will be sent.


    It''s not difficult to complete this research. After all, there are some wolves, such as the Kenai mountain wolf, which is 1.2 meters tall and more than two meters long. There are also polar wolves, which can resist the low temperature of minus 50 degrees. In addition, wolves and dogs are close relatives. It''s very easy to cultivate large wolves with enough body size, good endurance and cold tolerance.


    Of course, it''s also OK to breed on the basis of dogs, but relatively speaking, under normal circumstances, dogs are much smaller than wolves, and only a few large dogs are relatively large, so it''s easier to breed the large creatures Chen Xin needs on the basis of wolves.


    It is obviously not easy to cultivate a suitable large organism. In addition to genetic modification, we need to modify and adjust according to the cultivated living samples, and explore a suitable cultivation method.


    After all, this is a living animal, not a machine. After setting the program, it can move by itself.


    When it comes to machines, Chen Xin can''t help feeling his chin. Maybe Sox is also a good choice?


    Although it''s just a kind of toy setting, Chen Xin likes the long tooth lion series very much and has collected them.


    However, after thinking about it seriously, Chen Xin had to give up this idea. Although the appearance of Sox mechanical beast is just like the steel machine of Gundam and Titan, it is a metal life in the design.


    Even if you are just building a similar mecha, if you want to be able to fight in real life, the relevant requirements of artificial intelligence and machining are also very high, which is not something that the manufacturing capacity of the country can play well.


    So let''s make Titans easier to build first, and then consider building mechanical animals and Gundam.


    In addition, there is still a very important problem to be solved in order to prepare large cold tolerant wolves.


    As we all know, the reproduction of mammals requires the mother. After all, mammals are the species that develop their larvae in the mother until they reach a certain stage, which is different from the oviparous animals that develop in the eggs.


    So even if Chen Xin can get live embryos, he still needs the mother to breed them, or use artificial cultivation to make them mature.


    Artificial breeding is obviously not so easy, even before the disaster, all countries in the world are studying it, but the artificial uterus technology needed for artificial embryo cultivation is still not mature.


    However, this is simple for Chen xinlai. It doesn''t take much to make the training warehouse. The key is the technology.


    After all, Chen Xin only provides equipment, not technology, so he still needs experts in this field to assist in the research. This is the main work and research topic of the biological laboratory after the completion of the research base.


    In a word, after reorganizing his thinking, Chen Xin made a list of what he wanted to do.


    Of course, after the construction of the ecological dome of the scientific research base is completed, the connection between the scientific research base and its own refuge will be upgraded once again.


    The second is the cultivation of cold tolerant wolves, which is further divided into several sub items, such as cultivation barn manufacturing, wolf gene adjustment, embryo cultivation, individual training and live reproduction. It can be said that it is a long-term work.


    In fact, there is no priority gap between the third Titan manufacturing work and the second wolf breeding work. In this work, Chen Xin mainly makes Titan prototypes, and then helps the factory to realize technology cracking and reverse research, complete the construction of production line, so as to start the production of this combat weapon.


    As for other animal like body manufacturing and Gundam construction, or simply starting metal life cultivation and making real Sox beasts, they are all things that will be done later. We are not in a hurry now.


    And the fourth energy project research is also a very important research topic. Although there are three technologies such as controllable nuclear fusion, deep geothermal exploitation and isotope thermoelectric power generation, at present, these three technologies still have great potential to be tapped.


    In addition to these major projects, Chen Xin is also considering the manufacture of individual protective armor.


    Although the exoskeleton protective clothing has begun to be popularized, and the military has begun to use military exoskeletons, the protective ability is not bad, Chen Xin still wants to do some other things.For example, although Chen Xin made the whole body power armor, it has not been imitated or mass produced. The military has been greedy for this for a long time.


    In addition to the power armor itself, supporting weapons and vehicles carrying soldiers wearing power armor need to be developed.


    Weapons can also make do with the original weapons, but it is difficult for vehicles to make do with them.


    After all, a soldier''s total weight and body size change a lot after wearing power armor. Take the zhi20 helicopter as an example. A zhi20 helicopter could have sat down ten soldiers with ordinary equipment without carrying weapon modules, while a weapon rack could only carry eight soldiers.


    However, if it is to carry soldiers wearing power armor, even if it does not carry weapons, it can only carry six people and their equipment, and there is not enough space in the cabin to accommodate these soldiers and their power armor.


    This is especially true for armored personnel carriers. Even the height of ordinary soldiers is limited in the space of the carriage, not to mention the soldiers wearing power armor.


    In particular, the heavy-duty mecha Chen Xin provided to the military has not been mass-produced, but it can''t sit on any vehicles except trucks. Even helicopters can only be transported by lifting.


    Therefore, the development of relevant supporting vehicles must be carried out, which is also the focus of the military.


    Fortunately, the front army did not rely on Chen Xin, but let other relevant research institutions use the original vehicles for research and development. At present, it is said that the research progress is fairly good.

 Chapter 420

    After readjusting his status, Chen Xin stopped worrying about genetic modification and instead focused on several important things at hand.


    However, most of the projects need to wait for the completion of the construction of the scientific research base before they can start. The only thing that can be done is the research on military weapons.


    The R & D of Titan and large vehicles is limited by the site. Chen Xin didn''t do it right away. Instead, he planned to wait until the scientific research base was built and the conditions were ready to carry out the R & D work. Now he just planned to use the time before the scientific research base was built to make a few exoskeletons and power armor supporting weapons.


    If it''s just exoskeletons, it''s OK to use ordinary weapons. Although the power brought by exoskeletons is not very strong, it can at least make soldiers use heavier guns and weapons with stronger recoil force to play a more powerful firepower in the battlefield.


    The power armor is different. Apart from other things, the trigger of ordinary guns is designed according to the thickness of ordinary people''s fingers. You can wear tactical gloves or something, but if you wear heavy anti freezing gloves, your fingers are almost as thick as carrots. I''m afraid your fingers can''t fit into the trigger ring.


    Therefore, weapons equipped with power armor should at least be enlarged in the size of the trigger.


    What''s more, soldiers equipped with power armor are much stronger both in strength and load.


    In this case, using ordinary guns, they can even hold an automatic rifle in one hand and shoot continuously without holding and pressing the gun. So naturally, they can be equipped with heavy weapons such as 12.7mm Gatling machine gun, which can only be used with vehicles.


    However, the 12.7mm caliber is still too powerful. Apart from the main battle tank, ordinary vehicles, even armored vehicles, can hardly withstand the 12.7mm caliber armor piercing incendiary bombs.


    Chen Xin remembers that when the weapons research department of Yanguo designed the 12.7mm Gatling machine gun, it tested it with a car, and the car was directly shot through, not to mention the whole car.


    Therefore, it is inevitable to design a kind of gun with moderate power, which is more suitable for soldiers equipped with power armor to be used as ordinary weapons.


    After all, you can''t always carry a heavy machine gun that can tear ordinary people into two sections to perform tasks, can you? That''s too much firepower.


    "If you want to design a weapon for power armor, what do you think it should look like, Lieutenant Deng?" Chen Xin is holding a record board to ask second lieutenant Deng. At this time, Second Lieutenant Deng is testing the power armor made by Chen Xinxin.


    This set of power armor is made by Chen Xinxin, using the prototype design that Chen Xin had completed when he made his and Qin Lan''s power armor.


    And Chen Xin improved its power system, using the same small isotope thermoelectric battery as the exoskeleton power supply, but the output power was amplified a little, and some adjustments were made in flexibility.


    The whole power armor looks a bit like medieval knight plate armor, which is rather round due to the lack of edges and corners.


    In terms of design structure, this set of power armor is actually the design of exoskeleton packaging deck. On the whole, a set of exoskeleton is designed first, and then armor plates are installed on the exoskeleton skeleton.


    Unlike the two sets of Chen Xin and Qin LAN, the internal structure of the two sets is more complex power armor skeleton, not just exoskeleton armor.


    The reason for Chen Xin''s design is not that he is reluctant to give good things to the military, but that he needs to consider the manufacturing cost and whether the manufacturing process can support the complex design structure.


    People who know about World War II all know that Hans military industry is famous for its precise design and high quality, especially for tanks. Tiger, leopard and tiger king tanks are invincible in the battlefield. However, corresponding to them are complex structures and a large number of parts, which are not only troublesome to repair, but also time-consuming to build.


    Correspondingly, suvia''s T34 tank is simple in structure and hard to build. If it is damaged, it will be easier to repair. Even with maozi''s extensive maintenance style, it can stand up to setbacks, and it will be easier to manufacture. Even during the battle of Stalingrad, there was a story about the T34 made by a tractor factory going to the battlefield without painting.


    By comparison, we can see that it is very important for a country''s logistics and armaments to be simple, reliable and easy to maintain.


    Of course, Chen Xin can make power armor with advanced technology, comprehensive functions and powerful force, but that kind of thing is closer to the rich toys such as Iron Man Battle clothes, rather than a military equipment that can be used to train troops on a large scale.


    In addition, the country is now in mass production of exoskeleton, using the production line, using a large number of parts with the same specifications, can also reduce the investment in manufacturing, convenient and faster production.


    Lieutenant Deng didn''t feel much about this. He was quite satisfied with his power armor.


    Although it''s motion feedback power armor, he doesn''t feel any slow response. Basically, when his body moves, the power armor has already responded, and the efficiency is very good.


    As for Chen Xinwen''s question about weapons, Second Lieutenant Deng thought about it and said, "I think it''s necessary to have a stable and reliable automatic rifle. Although many weapons in games or science fiction works are tall, such as electromagnetism, Gauss and laser, they are simple and reliable, and can output fire continuously and stably."Chen Xin nodded. It''s no surprise that a good gun will not end with high precision and fast firing speed. What''s more important is its reliability and stability. Otherwise, the AK47 will not be the world''s highest production gun, even since World War II.


    "I see. I''ll pay attention to that." Chen Xin recorded Deng''s opinions and then asked him, "do you think there is any improvement in this set of power armor?"


    "Every aspect is very good, but our special forces will bring a lot of things when they are on duty. How can we load this set of power armor? Is it a plug-in carrying device? " Lieutenant Deng asked a key question.


    In all kinds of film and television works and video games, we usually don''t think about how the characters carry materials. The former is for aesthetic and visual effects, while the latter has omnipotent backpack space, and even doesn''t need to dig things.


    But it can''t be done in reality. Even Chen Xin himself has built a silo behind his power armor. This kind of power armor for the military must have a place for loading things, otherwise there is no place for ammunition and other things.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 421

    In a sense, it is very easy to make a gun, because there are only three necessary parts for a gun: the barrel, the barrel and the firing pin.


    The gun chamber is used to contain and excite ammunition. In the era of rifles, the gun chamber needs to have enough air tightness to ensure that the kinetic energy generated during the combustion of gunpowder will not leak out due to poor sealing, which will affect the range.


    The barrel is used to stabilize the trajectory of the bullet, so that the walk after the bullet is shot out of the muzzle will not become very terrible.


    The bullet also needs a firing pin to hit the cap at the bottom of the cartridge case, which stimulates the primer to ignite the gunpowder, so the firing pin is also an essential part of the gun.


    Therefore, if a gun has these three elements, it can be called a gun.


    As for the accessories with many other functions, such as ammunition feeding, air guiding, aiming and recoil slowing, they are not necessary in a sense, because the existence of these things is just more convenient for you to use the weapons in your hands.


    But if you want to design a good gun, these functions are needed.


    You need to slow down the recoil to stabilize the muzzle so that it doesn''t go up. At the same time, you need to make the muzzle more stable during continuous firing, so that it can play more intensive walks.


    You need an automatic ammunition feeding mechanism, because you can''t load one bullet at a time when it''s really fighting. That''s too inefficient.


    You need a good air guiding system to let the gas in the gun chamber after burning quickly and do not interfere with your sight. Although most of the bullet powder is smokeless powder, the gas itself has a certain temperature. If it is sprayed on the face, it is almost the same as directly facing the exhaust gas of the truck at close range, which is a very influential thing in combat.


    You also need a good targeting system to avoid all your hits by faith


    So it''s not easy to design a gun, especially a good one.


    Although Chen Xin has a lot of ready-made guns and sci-fi weapons as a reference, he still has no clue.


    Laser or laser, of course, can solve the problem of energy supply. This kind of weapon, which is very common in science fiction works, can be launched. However, if the power is too small, it has little practical significance. If the power is too large, it is not as cheap as traditional guns.


    If it''s just traditional firearms, Chen Xin doesn''t have any advantages in this respect, and he''s not as good as the current firearms designers in the country. If he only designs traditional firearms, he can send the use requirements to the national firearms designers for them to design.


    Even if a mature weapon needs a lot of time to design and modify in order to be finalized, it is not difficult to make simple modifications on the basis of existing weapons.


    So Chen Xin is more interested in electromagnetic rifles.


    Among all kinds of science fiction works, power armor with electromagnetic rifle is already a standard configuration. Not to say, electromagnetic rifle itself does not rely on the kinetic energy generated by gunpowder combustion as traditional guns, which can break through the upper limit of traditional guns'' bullet power, that is, the muzzle speed of 2000ms.


    What''s more, the electromagnetic rifle relies on the electromagnetic force to push the ammunition, so the ammunition of the electromagnetic gun can only be the projectile itself, instead of the shell and charge, which greatly reduces the weight of the ammunition, reduces the shell throwing time, and improves the firing speed.


    Of course, for modern wars, the power of bullets in World War II was too great, so we came up with such things as reducing the load of ammunition. Naturally, the power of guns and bullets was not too great.


    But considering that it is equipped for power armor, naturally there is a necessary requirement that it can at least penetrate power armor.


    Otherwise, when we really need to face the enemy who is equipped with power armor, the weapons in our hands can not penetrate the enemy''s armor, which will be very embarrassing.


    Although it can be said that heavy weapons can be used to forcibly destroy power armor, heavy weapons are heavy weapons after all, which can not be used casually and are not suitable for each person.


    So at this time, it is necessary to use electromagnetic rifle, which has enough power and many other advantages.


    But Chen Xin is now more difficult is how to design an electromagnetic rifle.


    The relevant principle of electromagnetic rifle is very simple, and even has certain hands-on ability to make a thing at home that can shoot bullets.


    It can be said that the technology is relatively mature, and even the military of Yan state has begun to equip experimental electromagnetic guns and rifles.


    As far as the form is concerned, the coil type is formed earlier, which can launch heavier projectiles with stable orbit and high shooting accuracy.


    The orbital type has a high initial velocity, and can adjust the width of two orbits to launch various shapes of projectiles. Not to mention, because of the high initial velocity, the range can also be very long.


    But as far as the electromagnetic rifle is concerned, the coil type is more practical than the track type, because the track type consumes more electric energy and higher consumption. As a single soldier weapon, it is not very practical.


    However, Chen Xin did not abandon the design of the Orbital Electromagnetic rifle. Instead, after making some modifications, he made a version of the sniper rifle. He planned to make one for Qin LAN, just to match her power armor.As for the electromagnetic rifle equipped for ordinary soldiers, Chen Xin decided to use the coil type.


    The production process is quite simple. After all, it''s only the basic application of physics knowledge in middle school. On the premise that Chen Xin doesn''t pursue to create too powerful things, it''s OK to find a steel pipe and wind a few circles of copper wire. At most, he can use 3D printing to make a shell.


    The rest of the work can be handed over to the system upgrade to deal with, a survival hit down, there will be a good electromagnetic rifle out.


    In fact, just like this, after the green light flashed, an electromagnetic rifle had been lying in front of Chen Xin.


    The model of this gun is based on the C-14 electromagnetic rifle of the machine gunners in the StarCraft series. It adopts the design of no butts and drum feeding. The bullet adopts the 7.62mm diameter pin cartridge. The barrel is a 40cm long coil barrel, and there is a picardini guide rail on the top of the barrel, which can be installed with different sighting devices.


    Compared with the C-14 electromagnetic rifle, the gun in front of Chen Xin is much thinner and lighter. At least Chen Xin can easily pick up the gun and launch it with one hand without power armor.


    The gun body is also powered by a high-performance battery installed under the barrel. One battery can support more than 2000 continuous shots, while one drum can load 70 rounds, which is enough to support a high-intensity battle.

 Chapter 422

    On a snowy slope outside the shelter, after a very light dull sound, Qin LAN looks a little strange and checks the gun in her hand.


    This gun is an electromagnetic sniper rifle specially made by Chen Xin for her. It is launched in orbit. Its initial speed is very high and its accuracy is quite good after her test. Even the wind resistance doesn''t need to be corrected. But somehow, Qin LAN still feels strange.


    "Alan, how do you feel? Is there anything else to adjust this gun?" Chen Xin sees Qin Lan''s face is strange, so she asks with concern.


    For this sniper rifle, Chen Xin is even more attentive than the ordinary electromagnetic rifle made for the military, and naturally hopes to achieve perfection.


    In the words of the game, what Chen Xin does for the military is a mass-produced version of blue-green equipment, while what he does for Qin LAN is at least a purple one, and Chen Xin seems to want to make it into an orange one.


    In the face of Chen Xin''s inquiry, Qin LAN organized a language and said: "it''s very comfortable to fight on the shooting hand. There''s no recoil, the trajectory is very stable, and the accuracy is also good. It''s just that I''m not used to it. I always feel strange. Maybe I haven''t used an electromagnetic rifle."


    "Feel strange? What''s so strange about it? " Chen Xinjian Qin Lan said so, took the gun from her hand, carefully checked it, and asked her.


    "I can''t say it. I don''t know how to describe it, but it''s different from the gun used before. It''s not that the gun is not easy to use, or it''s a bit unsuitable." Qin Lan thought about it, but she didn''t use this kind of electromagnetic weapon.


    Hearing Qin Lan''s words, Chen Xin thought about it and said, "can you describe the handle of this gun and the one you used before? What does it look like to compare the two? "


    "Well Although the accuracy of the gun used in the past is not so high, and the recoil force is also relatively strong, I can know what the result will be every time I shoot. The feedback from the gun itself is very good, "Qin Lan said, pausing for a moment and organizing the language to continue:" the exaggeration is that the original gun I can achieve the unity of man and gun, but now this gun is for me I feel strange.


    Although I also shot, I didn''t feel too much recoil, no muffler and no sound, so I didn''t know where the bullet would fly after shooting and what effect it would have after hitting. I couldn''t grasp all of these


    Qin Lan''s answer makes Chen Xin a little bit difficult. If Qin LAN can say the specific shortcomings, he can still make the revision.


    However, this kind of mysterious statement makes Chen Xin feel that he has no way to start. He doesn''t know how to modify it.


    Qin LAN seems to think that his statement is somewhat difficult, so he quickly added: "it''s not that this electromagnetic sniper gun is not easy to use, mainly because I''m not used to it. After you pull the trigger with this gun in your hand, there is almost no vibration. It doesn''t feel like you are shooting."


    Qin Lan said that to let Chen Xin seem to have a little understanding. He weighed the electromagnetic sniper rifle in his hand, raised the gun to aim directly, and then pulled the trigger.


    It was still a slight sound, and the bullet had hit the target in an instant, while Chen Xin only felt that the gun in his hand had a slight shock.


    After firing the gun, Chen Xin holds the gun and thinks seriously. He seems to have a little inspiration, but he can''t catch it.


    "The feeling of the gun It''s a little strange indeed. " Chen Xin also has to admit that the feeling of using this gun is really strange.


    In the past few hundred years, the guns used by human beings are powered by gunpowder. The recoil force produced by the natural gunpowder driving the projectile is also a problem that has plagued human beings for hundreds of years.


    Although modern military science and technology is developed, the recoil of the gun itself can be greatly reduced by the application of various accessories on the gun, but the recoil still exists.


    The slight frustration and vibration can make the gun user clearly feel the bullet flying out of the gun.


    Although this is not a practical feeling, for many people, it is a kind of feedback given by the gun to the user, especially for the sniper.


    Maybe not every sniper has such a habit. He feels that he has to feel the shock before he shoots the bullet. But it is obvious that Qin LAN prefers to feel the recoil or hear the gunshot.


    Although the recoil force of electromagnetic weapons is not to say that there is no recoil force, after the installation of the components to reduce the recoil force, the impact it can produce is very slight, even can not be described by feeling.


    It''s like playing with a toy gun. Even if you pull the trigger, it''s just a sound, but you don''t feel the gun jumping back or up.


    For Qin LAN, who has long been used to the obvious recoil feedback of traditional guns, this gun does not need to be loaded or shell thrown, and even has no recoil. It really feels strange.


    Chen Xin understood this point.


    As Qin Lan said, it''s not that the gun is not easy to use, it''s just that she is not used to it.


    Chen Xin can allow her to use more time to adapt to nature. Of course, she can also make some subtle adjustments to the gun body, so that it can provide clearer feedback.If it''s a weapon for the army, Chen Xin may not have to adjust it. But since it''s exclusive equipment for his girlfriend, Chen Xin decided to adjust the gun again.


    "I think I know what the problem is. I''ll take this gun and adjust it again." Chen Xin nodded to Qin LAN, saying that he already knew where the problem was.


    Seeing this, Qin LAN didn''t say anything more. She just nodded to Chen Xin full of expectation.


    For her, to be able to pick up the sniper gun again is what she has been looking forward to. After all, so many years of training has branded all the sniper in her soul, which is not so easy to give up.


    For a sniper, a good gun is undoubtedly the dream.


    After they had tried their guns, they walked back together. Because the space in the shelter was limited and the door was under construction, they chose a gentle snow slope nearby, which was just right for them to test their guns without interference.


    However, as they walked back, they suddenly felt the ground shaking.


    Chen Xin and Qin LAN steady body, look at each other, from each other''s eyes to see the surprise.


    "Is it an earthquake?" Qin LAN asks Chen Xin.


    "I don''t know, but it doesn''t feel very strong. Even if it''s an earthquake, it''s not our place." Chen Xin shook his head, only such a slight shaking, it is difficult to judge what is going on: "go back first!"

 Chapter 423

    When Chen Xin and Qin LAN returned to the shelter, the atmosphere here also seemed quite tense.


    The construction on the construction site has stopped temporarily, and all the workers are at a loss. They gather together and don''t know what to do.


    The soldiers of the special forces stood up, maintaining order, and guarding against possible dangers.


    Noticing Chen Xin and Qin Lan''s return, the commander and political commissar of the special forces came to Chen Xin and asked him, "academician Chen, do you know what happened? Was that an earthquake just now? "


    "I''m not sure about the specific situation. Did the shock have any impact? There were no casualties, were there Chen Xin asked the commander.


    As he asked, Chen Xin walked quickly to the special forces station, where there was communication equipment to contact the outside world. If he wanted to know what happened, the fastest way at present was to ask through the communication equipment.


    "Two workers accidentally fell off the scaffold. Fortunately, they fell on the snow. It''s OK." The commander replied to Chen Xin.


    Workers fall from the scaffold, which is of course a safety accident. It is reasonable to trace the cause, clarify the responsibility and investigate the potential safety hazards.


    It''s just that it''s more important to find out what happened just now.


    When he came to the barracks and contacted other places through communication equipment, Chen Xin quickly asked what happened to the vibration just now.


    If the earthquake is felt only in this city, it may be a small-scale earthquake or something. But if there are earthquakes in many places, it may be a larger earthquake or even a more serious thing.


    However, in the anxious waiting of Chen Xin, commander and others, the reply they received was a very bad answer.


    "There are obvious earthquakes in the area south of the Yangtze River in China. According to the seismic network, an earthquake with a magnitude of more than 9 on the Richter scale occurred in Southeast Asia. The epicenter is located in Sumatra island. The specific magnitude and detailed epicenter location are still being calculated..." Chen Xin looked at the reply, but his face turned pale.


    The commander on one side didn''t seem to know what was going on. He was still thankful: "fortunately, the earthquake didn''t happen in China. If Sumatra island, the magnitude 9 earthquake should not affect China. Now the sea should be frozen, not even tsunami... "


    However, before the commander''s words were finished, Qin LAN noticed the horror of Chen Xin''s expression and asked: "a Xin, what''s wrong with this?"


    "It''s probably not an earthquake..." Chen Xin shook his head. Although he thought of a very terrible possibility, he still didn''t want such a thing to happen: "no, we can''t make a blind judgment until the specific information comes out."


    Chen Xin shakes his head and says nothing. Instead, he stays in front of the communication equipment and seems to be waiting for the result.


    The commander and political commissar didn''t quite understand what was going on with Chen Xin at this time, but seeing Chen Xin''s dignified and worried face, they seemed to realize that things seemed more serious than they thought, so they both stayed and waited with Chen Xin.


    As time goes by, Chen Xin, who is in front of the communication equipment, is always cold, and even prays in a low voice not to be the worst result. Undoubtedly, this also affects other people, and makes them worry and nervous. They are afraid to go out.


    In such a repressive atmosphere, although the waiting time was less than half an hour, it was as long as the last half century.


    Finally, the communication equipment rings again, and a new message is sent.


    "The confirmed magnitude is 9.2 on the Richter scale, the epicenter is between 2.5 degrees north latitude and 98.4 degrees east longitude, and the epicenter is located in DOPA lake, Sumatra island..." The commissar read the message, but before he finished, Chen Xin sat down on the chair as if he had been shocked.


    Noticing Chen Xin''s strange appearance, Qin LAN quickly asked, "ah Xin, what''s the matter with you? What the hell is going on? What''s the matter? "


    The commissar and commander on one side also expressed concern to Chen Xin: "academician Chen, what''s the matter? Is there anything special about this place called DOPA lake? How did you get such a big reaction? "


    After repeated questioning, Chen Xin took a deep breath, and then explained to them in a low voice: "DOPA lake is the largest volcanic lake in the world. It was born more than 70000 years ago. It was formed by the huge crater left behind by the eruption of DOPA volcano. The eruption of DOPA volcano..."


    At this point, Chen Xinjian and his three men still didn''t seem to understand what was going on, but they all listened to their own explanation carefully. After sighing, they continued: "DOPA volcano is the second largest volcano in the world. It has erupted four times in history. The one more than 70000 years is the fourth and the most violent eruption of DOPA volcano, and it is also the blue star in the past 25 million years One of the most powerful volcanic eruptions.


    The whole eruption lasted for several weeks, and more than 3000 cubic kilometers of eruptions erupted from the volcano. In just three days, the volcanic ash had spread all over the world, the sky was gray, and the temperature also decreased. As a result, the whole blue star entered the glacial age, leading to a large number of species extinction, and the number of early humans at that time dropped to less than 2000 people Step"Ah?" After listening to Chen Xin''s explanation, the three people couldn''t help but make a voice of surprise. They didn''t expect that things would be so serious.


    "Maybe it''s just an earthquake, not a volcanic eruption? And this volcano has become a volcanic lake. In more than 70000 years, it has become an extinct volcano, right The commander said optimistically, and he also began to look forward to things not becoming so bad just like Chen Xin just now.


    However, Chen Xin shook his head and said helplessly: "DOPA volcano is not an extinct volcano. There is still a huge amount of magma in its magma pool. Once it is hit by an earthquake, it will erupt. Even if it is not a volcanic eruption this time, an earthquake of magnitude 9 or above will still trigger the eruption of this volcano, so DOPA volcano must have entered the stage of eruption.


    And now the key is not the eruption of this volcano, but whether its eruption is caused by the previous meteorite impact.


    If the geological activity caused by meteorite impact caused the eruption of DOPA volcano, then several other volcanoes are likely to erupt along with it. You should know that there are seven super volcanoes with the same grade as DOPA volcano on the blue star. If they erupt together, the world will really be over. "

 Chapter 424

    Chen Xin is able to find out where the problem lies. Naturally, it is impossible for the state to find out.


    The impact of super volcano eruption is also global, even not weaker than the disaster caused by meteorite impact.


    Take mount DOPA as an example. In history, the volcanic ash from its latest eruption spread to the whole blue star in three days, obscuring the sky, causing global haze and triggering volcanic winter, which lasted for several years.


    During this period, the global temperature plummeted and entered the glacial period. Not to mention, it caused a large number of animals and plants to die. Even the early human beings were almost extinct.


    Although human science and technology have been able to withstand this degree of disaster without being completely destroyed, it will still be greatly affected, and even the current civilization and social order of human beings may collapse.


    Although the human environment is bad enough, and the eruption of DOPA volcano may not make the problem worse, it is obviously impossible for the country to place its hope on no problem.


    So experts and scholars from all walks of life and relevant personnel have been called together to study whether the eruption of Mount DOPA will have a more serious impact on Yanguo.


    Chen Xin thought that this kind of thing would not call him. After all, he didn''t think he was an expert or scholar.


    However, with the title of academician, he was also on the list called by the state. Two helicopters flew directly to his refuge to take him to Chongqing, the temporary capital of Yan state.


    Although he was surprised that the state even called him in, Chen Xin quickly packed up his belongings and got on the plane.


    Because of the urgency and confidentiality of the incident, no one else was with Chen Xin. Only Lieutenant Deng, who was responsible for protecting Chen Xin, was allowed to follow Chen Xin on the plane.


    Two helicopters took off quickly and flew into the vast night. They came all of a sudden and went in a hurry.


    The two helicopters are straight 20, but they are different from the straight 20 Chen Xin had seen before. The two helicopters are full of weapons on both sides of the fuselage, and even equipped with machine gun pods under the nose, which can be called fully armed.


    Naturally, the feeling of riding in a military helicopter is not comfortable. Even because of the weather, the temperature in the cabin is very low. If the pilot and the people in the cabin, including Chen Xin, are not wearing protective clothing, I''m afraid that no one will be frostbitten.


    "How long are we going to fly?" Wearing the noise reduction earphone used in cabin communication, Chen Xin inquires through the microphone on the earphone.


    "It''s about 800 kilometers from here to Chongqing. We need to fly for two and a half hours." The pilot explained to Chen Xin, adding: "but we need to refuel halfway, so the whole journey takes three hours."


    Hearing what the pilot said, Chen Xin nodded slightly to show that he understood. He leaned against the cabin wall and closed his eyes slightly.


    During the flight, there was no light in the cabin, so Chen Xin couldn''t do anything to pass the time when it was dark. On the contrary, taking a rest with eyes closed was the most suitable choice.


    In three hours, Chen Xin''s helicopter arrived in the sky of Chongqing city.


    It''s not that Chen Xin has never been to Chongqing. Chen Xin, an 8D magic city famous in Yan Kingdom and even in the world, has heard about it for a long time. He also came to Chongqing in person at that time and had a relationship with a sister from Sichuan.


    But things have changed, the original thing has already died, I do not know where the girl is now?


    Chen Xin''s face became a little complicated and strange when he looked at the dark Chongqing City dotted with lights outside the window.


    Colorful lights, cities shrouded in darkness, a world on the verge of destruction, imminent disasters, people struggling to survive


    If all this is just a novel, these elements are quite interesting. It''s easy to write a good novel if the level of the writer is acceptable and the writing style is OK.


    However, it is obvious that what is in front of us is not the plot of the novel, but the real reality. What mankind is facing at this moment is the real crisis of extermination. Even Chen Xin is just thinking about it. He doesn''t have the mind to think about the plot of the novel, and soon draws his own thinking back to the business.


    In fact, the direct impact of super volcanic eruption on Yanguo is not great. Even though Sumatra is not far away from Yanguo, the biggest direct impact is the slight earthquake before and the volcanic ash that may fall after.


    But the indirect impact is hard to say. Although the whole world is covered by the thick dust formed by the previous meteorite impact, the global temperature has already dropped to tens of degrees below zero. In this case, even if the volcanic eruption caused the volcanic winter, it will not make the situation worse.


    However, all kinds of poisonous and harmful gases brought by volcanic eruption can not be ignored. The air quality itself is not good. Now that volcanoes come to join in the fun, it can be imagined that the external living environment will only become worse.What''s more, what worries Chen Xin is the cause of the eruption.


    If this is just a volcanic eruption caused by normal geological activities, the impact may not be great, and it may only affect Southeast Asia.


    Although it''s very inhumane to say that, if it''s just a disaster in Southeast Asia, Chen Xin may have to applaud and celebrate. After all, it''s very different to only affect Southeast Asia and the whole blue star.


    But if this volcanic eruption was caused by a previous meteorite impact, Chen Xinke will have to worry more about some problems.


    At the beginning, the impact point of the meteorite was between Australia and Hawaii. Hawaii itself is a volcanic island. Not to mention, it also belongs to the zone with relatively weak crust. The impact of the meteorite is likely to cause a wide range of geological disasters, and even affect volcanoes around the world.


    If the eruption of DOPA volcano is just the beginning, and then there will be global geological changes that will lead to global volcanic activity, and each super volcano will enter the active period to erupt one after another, it will be really great fun for all mankind.


    A super volcano is enough to destroy the ecology on the surface of a blue star. If the super volcanoes all over the world erupt together, the volcanic ash will be enough to bury the whole earth.


    If so, the consequences will be very serious.


    Although the human situation is very difficult, it is not to the point of extinction. However, if the global super volcanoes erupt together, it is really time for human beings to consider pointing the middle finger.


    Is this terrible? Yes, it''s terrible.

 Chapter 425

    The helicopter landed on a specially cleared apron. Chen Xin stepped down from the helicopter and looked around. It seemed to be the top of a building, but there were other high-rise buildings beside it. It looked like he was at the bottom of a building.


    This is also the characteristic of Chongqing city. This mountain city will always encounter such magical things. After all, due to the limitation of the terrain, the buildings can only be built according to the mountains.


    However, it also brought many benefits to Chongqing. Before the disaster, this unique landscape became a unique feature of Chongqing. It not only attracted a large number of tourists every year, but also made it into the game.


    In the past, Chongqing was full of cyberpunk style.


    Even now, this special terrain is still providing benefits for Chongqing.


    Many mountains mean many obstacles. In addition, Chongqing has dug many air raid shelters since the war years, which makes Chongqing not seriously affected in the previous disasters.


    Although many buildings have been damaged, on the whole, Chongqing should be considered as the lightest large city in the territory of Yanguo, otherwise the high-rise buildings would not choose the capital of Linshi here.


    The light disaster situation means that the post disaster reconstruction and recovery is fast.


    When Chen Xin looked down from the sky just now, the stars he saw were the results of Chongqing''s post disaster reconstruction.


    Although it can''t be compared with the neon city before the disaster, at least it won''t make the earth dark and recover some vitality.


    However, Chen Xingen was not able to take a close look at the scenery, so he came to receive his own staff. He took Lieutenant Deng through several snow swept streets, entered a building, climbed several stairs, and came out of another street.


    Again through a few stairs, a few times around, but did not climb the stairs, but entered an air raid shelter.


    When entering the air raid shelter, Chen Xin looked up on both sides and could still see the sign of "Dongzi hot pot", but it was covered with dust and looked rather decadent.


    However, Chen Xingen could not feel it. He followed the staff through the air raid shelter where no one lived, and suddenly his eyes lit up and opened up a lot.


    At this time, the staff in charge of the guidance introduced to Chen Xin: "there are many air raid shelters and civil air defense facilities in Chongqing. Before the disaster, the state decided to move the temporary capital to Chongqing. After the disaster, the municipal government of Chongqing decided to vigorously build underground space, so that more people can enter it for refuge and survival.


    So they have connected most of the original air raid shelters, hollowed out several mountains, built large underground shelters and underground roads, and we are now in a shelter on one of the main roads, from which we can go to the meeting place by car. "


    If it''s normal, Chen Xin may feel for the underground space which is at least tens of meters high, but the threat brought by super volcano eruption makes him have no intention to think about these things.


    Under the arrangement of the staff, they got on a prepared special car with Lieutenant Deng and drove to their destination.


    Chongqing used to be a city with few level roads, and there was even a joke that no one rode a bicycle in Chongqing, because there were too many uphill and downhill, and the time for wheelbarrow was too much longer than cycling.


    However, the underground road excavated in the mountain is quite flat, and there is no change in the uphill and downhill. After a few turns, the special car takes Chen Xin to his destination, an underground refuge obviously different from other places.


    There are not only soldiers in the same military exoskeletons as Lieutenant Deng, but also heavy machine armour made by Chen Xin for the military. Only after passing the inspection can they move away and put people in.


    Chen Xin couldn''t help looking at the heavy mecha. It''s not a month since he handed it over to the state. Now he can see the heavy mecha that has been put into use, which makes Chen Xin feel a bit surprised.


    Maybe they had said hello before. After the staff showed their identification, they passed the inspection quickly and were able to enter the shelter.


    After entering the shelter, the car stopped quickly. Chen Xin got out of the car with the staff and looked up to see that he was in a parking lot. There were other cars coming in next to him. All the experts and scholars who came down were also invited.


    Some of them noticed Chen Xin, but everyone''s face was heavy, so they just nodded and said hello, and then hurried away. No one was here to exchange greetings.


    If they are other experts and scholars, they may know other people because they have been in the academic circle for a long time. However, for Chen Xin, these experts and scholars are very strange. He knows no one except a few people who may have seen them on TV or in textbooks.


    Therefore, he did not stay here, so he followed the staff to leave the parking lot.


    It seems that this refuge is specially divided for the reception of these experts and scholars, and the conditions look good. At least it is cleaner and brighter than other shelters Chen Xin has seen.


    The staff led Chen xinlai to a room. There was a sign with Chen Xin''s name at the door."Academician Chen, this is the room arranged for you. As the participants are not all here yet, please have a rest here. We will inform you when the meeting starts." The staff opened the door and introduced Chen Xin into the room: "there is a canteen, just upstairs. If you feel hungry and need to eat, you can call someone to deliver your meal through the internal telephone, or you can go to the canteen to eat by yourself. You don''t need to spend money to eat here. You just need to show your ID card.


    In addition, this is the relevant information we have so far. You can have a look at it before the meeting. "


    With that, the staff handed a certificate and a piece of information to Chen Xin.


    Chen Xin took the certificate and looked over it. It only had a few words on it. It looked like it was left over from some meetings before the disaster.


    However, it''s very good to have a certificate for this kind of temporary meeting. It''s unrealistic to do something new within a few hours, and it''s also a waste of resources.


    In addition to the certificate, the staff also gave Chen Xin a magnetic card, which is commonly used inside the shelter. Each participant can get one card to pass through the doors with access control.


    After giving the things to Chen Xin, the staff left the room, leaving Chen Xin and lieutenant Deng behind.


    "Academician Chen, would you like to have a rest first?" Second lieutenant Deng looked at Chen Xin and asked him.


    After more than three hours'' helicopter ride, I feel a little tired.


    However, Chen Xin shook his head, raised the information in his hand to lieutenant Deng, and said to him, "I want to see the information. Go and get me something to eat."

 Chapter 426

    Because it was an emergency meeting, and the military used helicopters to directly pick up the people, the participants soon arrived, and the meeting also started immediately after the personnel arrived.


    Chen Xin walked into the venue alone. Due to security restrictions, Lt. Deng was obviously not qualified to enter, so Chen Xin was the only one.


    Entering the meeting hall, Chen Xin couldn''t help looking around to see what people were coming to the meeting.


    However, most of them were strangers or had only seen them on TV, and most of them looked serious. The atmosphere of the meeting was dignified, which made Chen Xin instinctively want to sit in a corner.


    After all, it''s the first time for Chen Xin to attend a meeting of this kind. Chen Xin is unavoidably nervous. Moreover, he feels that he is not a real expert and scholar, and it''s not his turn to speak. Just sit in an inconspicuous position and go back after the meeting.


    Just as Chen Xingang was about to go to the corner, a staff member found him and quickly came over to Chen Xin and said, "are you academician Chen Xin? Your seat is at the front. Let me show you there. "


    With that, he led Chen Xin to the front row of the conference room and arranged Chen Xin in a very prominent position.


    People around him couldn''t help gazing at him for a few seconds. After all, Chen Xin is too young to find any younger participants in this conference room except the staff.


    In particular, with other participants seated, Chen Xin was surrounded by white haired elders, especially many people Chen Xin had seen on TV, and his name even appeared in textbooks, which made Chen Xin more restless.


    If he didn''t know the importance of the meeting and how much he had seen the big scenes, Chen Xinzhen would have the impulse to seize the door and run away.


    Although relying on the system, Chen Xin is now an academician and a talent of great importance to the country, the talents around him are the real treasures of the country.


    In the past, Chen Xin probably only thought that he could be with such a group of people when he was writing novels. As for joining them, it was something Chen Xin never dreamed of.


    Fortunately, this cautious attitude did not last long. With the entrance of the high-level leaders who presided over the meeting, the meeting began directly.


    ¡°¡­¡­ From the analysis of the data obtained at present, the eruption of DOPA volcano has not caused much impact on China, but affected by it, the seismic belt in Southwest China will become active, and the probability of geological activity in Southwest China will increase in the future... "


    ¡°¡­¡­ The meteorological department predicts that the volcanic ash will spread to China in the next week, but it will not affect the existing climate. The volcanic ash may land in Hainan, Guangdong, Yunnan and Tibet, and the specific impact on the local area needs further analysis. "


    ¡°¡­¡­ At present, the transportation department has made preparations. Forty nuclear powered locomotives and sixteen newly developed nuclear refuge trains can be put into the work of material transportation and personnel transfer at any time. The comrades on the railway front will spare no effort to ensure the smooth flow of the main railway lines.... "


    ¡°¡­¡­ In aviation, at present, only helicopters can take off. Although we have urgently transformed the existing military transport helicopters, the current transport capacity is mainly used to ensure the transportation of materials in Plateau and remote areas. It is impossible to deploy a large number of transport planes, and the reserve of available aviation fuel is still tight, unless strategic reserves are used... "


    ¡°¡­¡­ The agricultural production in Lingnan mountain area and Qiongzhou area may be affected by the volcanic ash, but from the current situation, it may have little impact. However, if an earthquake occurs in the southwest area, it may have a significant impact on the agricultural production in the Qinghai Tibet Plateau. The current material supply in Tibet Province depends entirely on the Sichuan Tibet railway. If the railway transportation is interrupted, the consequences will be unimaginable... "


    In the conference room, participants from various departments talked in their own fields about the possible impact of the eruption of Toba volcano on the country.


    At this time, Chen Xin wanted to speak, but he didn''t know where to start, and even some couldn''t get in the way. He didn''t understand what some experts said.


    However, from the speeches made by these people, Chen Xin still understood that the impact of the eruption of DOPA volcano on Yanguo was mainly due to geological activities.


    The southwest area of Yanguo is in the seismic belt itself, which is also an earthquake prone area. If the eruption of DOPA volcano causes the seismic belt in the southwest area to be active, then it is likely to lead to frequent earthquakes in the southwest area.


    Earthquake disaster can be large or small, a slight earthquake is nothing more than shaking, even the human body has no feeling, but a serious earthquake


    Everyone who has experienced the earthquake in Yanguo will not forget the earthquake that affected hundreds of millions of people in Sichuan Province.


    Especially in the current situation where everyone lives in underground shelters, once there is a severe earthquake that is serious enough to destroy buildings or even change the terrain, the casualties will be unimaginable.


    However, it is impossible for Yanguo to move the population of the whole southwest region because of the possibility of an earthquake. This is not only because of the large population in the southwest region, but also because the migration of these people will bring a huge amount of work and various follow-up problems.What''s more, Southwest China has always been the strategic rear area of Yanguo. At present, the southeast coast of Yanguo and even the middle and lower reaches of the Yangtze River are inundated and frozen by the rising sea water, so it becomes more important for Southwest China to be less affected by disasters.


    It is obviously impossible for the state to give up the southwest region in this case.


    In the current situation, it is best that the southwest region is not affected. But if the southwest region is affected, on the premise of not giving up the whole southwest, it can only enhance the ability of the southwest region to resist disasters.


    What is needed to resist disasters?


    Chen Xin turned over the materials from the meeting and wrote such a line in the blank on the back with a pen.


    The most important thing for human beings to maintain life is clothing, food, housing and transportation. Clothes now have exoskeleton protective clothing, which is enough for civilian use. Whether it is cold and warm or going out to work, they are competent. Even if there is a real disaster, there is no problem for disaster relief.


    Although food is not completely guaranteed, at least there is no hunger crisis. However, Chen Xin heard from an agricultural population just now that food consumption and stable supply have not yet been realized in China.


    At present, the consumption is all the materials stored by the state before the disaster. Even if the grain production in Hainan Province and Lingnan region is not affected, it can not meet the needs of the whole country.


    Therefore, although the food problem is not imminent, it must be dealt with in time at least. Ecological three-dimensional agriculture may be the first problem to be solved later.


    Chen Xin''s fingers beat on the table, but his thoughts focused on the remaining two things.


    "Live" and "go".

    While Chen Xin was thinking about the problem, the meeting continued.


    All aspects of the problems and situations have been summarized in front of the senior leaders. For the possible impact and problems caused by dopa volcano, all departments have done a good job in the discussion.


    It''s just that the previous meteorite impact eventually brought serious damage to Yanguo and the whole world. Even though Yanguo has been reconstructed and recovered a lot, there are corresponding countermeasures and plans, but the situation is still not optimistic.


    ¡°¡­¡­ Judging from the current situation, China''s current emergency response capacity and rescue forces are only 30% or less of those before the disaster, and the transportation capacity is also stretched. If there is a large-scale geological disaster in Southwest China, we are unable to mobilize enough forces to carry out the rescue work. " An official finished his report with a heavy expression on his face.


    Although Yanguo is the country with the strongest mobilization ability on the blue star, in the face of all kinds of disasters, the government of Yanguo has never given up any of its people, but the disaster hit the whole blue star too much. Even Yanguo has not retained enough strength, and it can no longer mobilize the strength of the whole country to rescue a place as it did before the disaster.


    It''s not just a loss of economic power, transportation, communications, production, material reserves After suffering devastating damage in many fields, Yanguo is now like a giant who has been seriously injured. Although the injury is improving and recovering, it is no longer able to clench its fist and use its whole strength.


    Now Yanguo is like a weak giant, he not only needs to recuperate, but also needs to repair his own damage.


    "Is it still a transportation problem? Do comrades from the transportation department have any solutions? " The senior leaders who presided over the meeting could not help but frown and look at the representatives of the transportation department.


    "This I''m afraid it''s hard! " At this time, the representative of the transportation department was also helpless and explained to the leader: "at present, all the highway traffic in the country is basically paralyzed, even if it is only between regions, it is almost impossible. The country now relies on railway transportation to maintain the basic material circulation.


    In aviation, all jet aircraft can''t take off, and the dust and particles suspended in the air have a great impact on the aircraft engine. Even if we have the air filter device that can be used for aircraft engine before, we can only let helicopters and some old propeller aircraft fly.


    However, the range of helicopters is limited, and the number and transport capacity of old propeller aircraft are insufficient. Generally speaking, the transport capacity of aviation is very difficult to achieve, and what can be achieved at present is only the emergency transport of a small amount of materials and personnel.


    If we want to restore our aviation capacity, we need an aircraft that can carry at least 20 tons of cargo, take off in this weather, and have a range of more than 3000 kilometers. "


    Hearing what the representative of the transportation department said, the leader could only nod his head with a heavy expression. Instead of embarrassing the people in the transportation department, he turned his eyes to the position of the people in the scientific research institutions and asked, "what can the comrades in the scientific research institutions say? Can the requirements put forward by comrades in the transportation department be met? "


    "This..." The representative of the scientific research institution was puzzled for a moment. Scientific research can''t produce results in a short time. He can''t produce such a plane that can meet the requirements.


    However, when the representatives of scientific research institutions were in a dilemma, Chen Xin suddenly raised his hand to indicate that he wanted to speak, and then asked, "what about Yun 9? I remember that yun-9 can take off at Lhasa airport with a load of 15 tons and a range of more than 3000 kilometers. It is also a medium range transport aircraft with propeller engine. Can''t it meet the requirements? "


    "Yun-9 uses a turboprop engine, which also requires a lot of air intake. Although we can install an air filter on it, it will greatly affect its engine efficiency, resulting in a serious drop in the weight and speed of the aircraft during takeoff." Next to a representative of a scientific research institution is an expert in aircraft R & D and manufacturing. While answering Chen Xin''s question, he added: "although the problem can be avoided by using piston engine, it is a very troublesome and complicated project to replace an aircraft, especially one with different working principles. Although we can do so, it is still a short time and a half I''m afraid I can''t finish the work. "


    Chen Xin can''t say anything more about this. Although there are large, medium and small models of domestic transport aircraft, before the disaster, everyone has gradually abandoned the old piston propeller and replaced it with turboprop in order to achieve higher efficiency and lower fuel consumption.


    Moreover, the aircraft itself is very delicate, and it has certain requirements for the weather and environment of flight. It is not too strange that we can''t get a usable aircraft under such circumstances.


    "It''s hard for you. You''d better take out a plane that can fly as soon as possible. The time is tight and the task is heavy, but it''s still a burden to you." Although leaders can also understand objective facts, they still put forward requirements.


    In the face of the leadership''s request, the scientific research department after a discussion, or nodded down.


    When Chen Xin listened to the leader''s assignment, he suddenly recalled what he had just thought.


    Food, clothing, housing and transportation, food and clothing for the time being, shelter for the time being, Chen Xin can''t worry about it. What about that?From the current situation, transportation is obviously a big problem. Let''s not mention the highway for the time being. The railway can cope with nuclear power, but the aviation does not have the right aircraft.


    Chen Xin thought about it, then raised his hand and said, "if I need a plane, I should be able to provide one that meets the requirements of the transportation department."


    "Are you academician Chen Xin? I''ve heard of you and know your skills. Can you really provide a plane that can meet the requirements of comrades in the transportation department? " The leader looked at Chen Xin unexpectedly, and was obviously surprised that he suddenly said that he could provide aircraft.


    "To carry more than 20 tons of cargo, we can take off in this weather and sail more than 3000 kilometers. If these are the only conditions, I can meet them." Chen Xin is full of confidence: "however, I need the design drawings and research data of yun-9, as well as a yun-9 as a sample for research and transformation. Within a week, I can come up with a feasible design scheme."


    "If you really can do it, academician Chen, I can meet these requirements, but this is not a joke. Can you bear the responsibility?" The leader heard Chen Xin say so and looked at him very seriously.


    Chen Xin nodded his head and answered with the same seriousness: "dare to set up a military order."

 Chapter 428

    "Academician Chen, how do you take out a plane that can meet the requirements within a week? This is no joke At the end of the meeting, representatives of scientific research institutions, together with experts in aircraft R & D and manufacturing, found Chen Xin and asked him with concern.


    Your expert in aircraft R & D and manufacturing is also frowning, because with his decades of work experience, he can''t figure out why Chen Xin dares to come up with a solution in a week.


    The number of years for designing an aircraft has always been based on years. Yun-9 transport aircraft was first approved in 1969, and it didn''t officially appear until 2005.


    Although there are all kinds of problems in the middle that lead to the interruption of the research and development of yun-9, the time needed for aircraft research and development can also be seen.


    Even if Chen Xin only makes improvements on Yun 9, it''s not something that can be accomplished in a week.


    Of course, Chen Xin has a good idea of this problem, but he also knows that the problem can not be solved by one plane.


    What they say about an aircraft is not a simple one, but a model, or a solution that can make a batch of ready-made aircraft fly in a short time.


    This may be impossible for others, but for Chen Xin, one week is enough.


    "Please don''t worry, I have already set up a military order in front of the leaders, so I won''t make fun of this kind of thing." The two in front of Chen Xinchong''s eyes laughed and explained to them, "yun-9 is a very well-designed aircraft with ready-made models. On the basis of it, I don''t need to make any major changes.


    We only need to improve the engine and intake duct of the aircraft, so that the aircraft can be competent for the immediate environment, and then we can meet the requirements and complete the task.


    Although it''s a bit tight in a week, I''m confident that I can handle it. "


    "That''s what I said, but are you sure, academician Chen?" Experts confirm to Chen Xin, he is still worried about Chen Xin is really able to complete the task: "Yun 9 design I also know, or I''ll help you!"


    "Thank you for your kindness, but you should have some important work to do yourself? Please believe me, since I dare to make a pledge and set up a military order, I will have enough assurance to complete the task. " Chen Xin declined the expert''s kindness, and had a system to help Chen Xin, who was confident enough to solve the problem himself. Of course, he didn''t need to waste other people''s time to help himself.


    Seeing that Chen Xin is so confident, the representatives and experts have no choice but to acquiesce to his practice of completing this task independently.


    "Why not use airships? The Zeppelin airship is a bit slow, but it should still be useful in this kind of environment? " Chen Xin thought of an old flying tool and asked the representative in doubt.


    Airship first appeared in the 19th century. At that time, although it was a new type of aircraft, it was not very mature and practical.


    It was not until 1900 that the Earl of Zeppelin of Hans built the world''s first hard airship that this kind of aircraft really matured and began to shine.


    Not only for civilian use, but also in the era when there was no aircraft, this kind of large aircraft that could fly into the sky was widely used in the military.


    This also gave birth to the largest aircraft in human history - the Hindenburg airship.


    The 803 foot giant has an amazing volume, which can accommodate 72 passengers. In the era when the plane was not able to fly across the Atlantic Ocean, it took only two days to fly to the other side of the ocean, and it took five days to complete the whole journey. At that time, it was amazing when only cruise ships could cross the Atlantic Ocean.


    Of course, the load capacity of such a large airship was not high. At that time, in order to ensure the smooth launch of the airship, everything on the airship was reduced, and the carrying capacity was still not high.


    Although it has a huge size comparable to Titanic, but at most, together with the staff, it did not carry 100 people.


    In 1937, the Hindenburg suffered an air crash, which completely burned down in a short time of 32 seconds. It also declared the decline of the era of airship. Since then, human beings have never built a large airship, and the related research has gradually re emerged in recent years.


    However, although there are various problems with airship, it can still play a role in the current situation where this kind of aircraft can not be used.


    However, the representative shook his head and said helplessly: "airships can really be used, but their cost performance is too low. The cost of soft airships is relatively low, but the load is not high. It may be no problem to transport a few people, but large hard airships are still needed to transport materials.


    But the cost of a large hard airship Not to mention the cost, the carrying capacity and flying speed will not be good after it is built. It''s better to build an old propeller airplane! "


    "This is also..." Chen Xin touched his chin, but he didn''t think of it.


    When the representatives and experts saw that Chen Xin had made up his mind, they had no intention of persuading him again, so they said a few words when necessary, and then left.


    Soon after that, the yun9 design materials Chen Xin needed were sent over, and the aircraft he needed was in a combat readiness airport in Chongqing.In the past, the design data of yun-9 could be filled with only drawings, but now it only needs a hard disk.


    Looking at the design drawings of Yun 9 on the computer, although Chen Xin doesn''t quite understand these things, he can still understand the drawings.


    In fact, the Y9 itself can carry the mission in the current harsh environment, but the key lies in the air inlet of the engine.


    Even if you 9 uses a turboprop engine, the demand for air intake is only a little less than that of a turbojet engine.


    Yun-9 has four engines in total. The turboprop-6c engine independently developed by Yanguo is used. Its output power is up to 5100 horsepower, or 3751kw. It is obviously impossible to replace it with a piston engine.


    Even if Chen Xin can use the system upgrade to directly change the engine on the plane to piston type, it is a big project to replace all the planes in the country.


    Therefore, the solution that Chen Xin can provide must be a method that can solve the problem in a short time and with little investment. Otherwise, although it is not useless, it is not so practical for the country.


    After all, if it is a replacement, the cost and time of replacement and the cost and time of engine production are a huge consumption. In the current situation of facing crisis, there is no time for slow work.


    Therefore, for Chen Xin, the best way to solve the problem is, of course, to improve the intake duct of the aircraft and install the air filter device, as he did on the helicopter.


    You should know that after the eruption of DOPA volcano, in addition to the dust and particles brought by the previous meteorite impact, there will be a large amount of volcanic ash suspended in the air.

 Chapter 429

    In a combat readiness airport in Chongqing, a long-standing yun-9 was maintained and renewed, waiting for Chen Xin''s arrival with a group of ground crew.


    Since the disaster, all the planes in the country have been sealed up, and the ground crew who used to maintain the planes naturally have nothing to do.


    Although it is necessary to maintain the aircraft from aging or damage due to storage, compared with the usual workload, it is so much less that these ground services become idle.


    Of course, the state did not say to let these people stay idle all the time. Apart from maintaining the sealed aircraft every other time, they were also seconded to other departments.


    Now the ground service team is still aware that Chen Xin needs a plane to do transformation research, and then temporarily recalled it.


    Such a temporary recall is also a bit abrupt for the ground crew. After receiving the order, they almost completed the maintenance of the sealed yun-9 overnight. After a simple rest, they gathered again, waiting for Chen Xin''s arrival.


    "What do you mean when they suddenly call us together? Do you mean these planes can fly again? " A stout ground technician was listening to others and guessing the purpose of the country''s sudden call to them.


    Another ground technician looked a little tired and drooped. He looked as if he hadn''t had a good rest for a long time. He took the conversation and replied, "can''t you fly? I was asked before when I was loaned to land airlines to help them install air filters for helicopters. They said that jet planes can''t fly yet. "


    "Well? Air filters for helicopters? Who thought of it? Does it work? " The ground service technician, with a strong body, was surprised when he heard the news. He immediately guessed: "will we be called to install air filters for yun-9?"


    "The helicopter is quite useful, at least straight 20 is able to fly, but Yun 9 words..." The exhausted ground technician shook his head and yawned before he continued: "the air intake of Yun 9 is much more than that of Zhi 20, so installing air filter may not solve the problem, right?


    And I heard from the ground crew over there that although they were able to fly, the load of the plane dropped a lot, and the air filter still had an impact on the air intake. "


    "Well, never mind what we are called to do. It''s good to come back to repair the plane. I don''t want to move materials to the warehouse every day." Another ground service technician could not help but express a sigh.


    While a group of ground service technicians were chatting, Chen Xin finally arrived at the combat readiness airport with several staff members.


    "Stop talking, someone is coming!" Some people have sharp eyes. Seeing Chen Xin and others coming in, they quickly shout to others.


    All the ground service technicians quickly stopped the topic and stood together, watching Chen Xin and others come to them with some nervousness.


    "Let me introduce you. This is academician Chen Xin of the Chinese Academy of Sciences. He will be responsible for the transformation project of yun-9 transport aircraft in the next week. You need to assist academician Chen to complete the relevant transformation tasks in this week." The staff introduced Chen Xin to the ground service technicians and also explained the task.


    While the staff stressed the importance of this task, Chen Xin also looked at the ground service technicians.


    Although these ground service technicians are not yellow and thin, most of them are a little pale because they haven''t been in the sun for a long time. In addition to some malnutrition, most of them don''t look very good. Some of them even have dark circles under their eyes and look tired.


    Chen Xin knew that they had just finished the maintenance of Yun 9 last night. It was understandable that they were a little tired. So after the staff finished, he said to these ground technicians, "last night, you should have done the maintenance of Yun 9 overnight, right? People who are too tired can go to rest first. I can''t use so many people now, just leave a few people to help. "


    With that, Chen Xin turned to the staff and handed him a USB flash drive: "here are some parts needed for the transformation. Please arrange for someone to make them for me as soon as possible."


    "OK, I''ll arrange it now." Staff took the U disk, nodded, no longer polite, then turned away.


    A week''s time is really tight, there is no time for greetings and courtesy.


    After the staff left, Chen Xin looked at the ground service technicians in front of him. Some of them were really tired and seemed to be unable to bear the burden. They wanted to have a rest, but they were a little embarrassed and didn''t want to leave first.


    Chen Xin didn''t say much about it. He just ordered two ground service technicians who seemed to be in good condition and took them to Yun 9.


    The rest of the ground technicians looked at each other, a few of them were too tired. Then they said hello to the others and went to the side room to have a rest.


    This is the combat readiness airport, or there is a place for these ground service technicians to rest.


    Chen Xin came under the wing of yun-9, looked up at the air inlet of one of the engines, and asked the ground technician beside him, "can you remove the whole engine, the intake duct and the propeller?"


    "The process is troublesome, but it can be disassembled." Before that, the thick ground technician stood beside Chen Xin and nodded to show that there was no problem."First remove one. I''ll let someone do the air filter. Let''s see if the engine and intake duct can be modified." Chen Xin said to the ground service technician beside him, but he himself had a ladder brought by someone, put it under the wing, climbed up and looked at the air intake culvert at a close distance.


    The intake duct of yun-9 is not small. Although it is not as exaggerated as that of jet engine, it still allows people to climb in directly.


    As a matter of fact, the inspection and maintenance of the air intake duct of an aircraft do require people to climb in for inspection. It is the ground service that usually does these things.


    For example, after the fighter plane flies back, even if the temperature in the intake duct has not dissipated, these ground service technicians must climb in to check whether there is any abnormality or damage in the intake duct, and then repair and deal with it in time.


    At this time, Chen Xin stood on the ladder, looked at the black air intake duct in front of him, touched his chin, released some nano molecules from the wrist watch, formed a measuring tool, and measured the air intake duct.


    Although transformation is an idea for Chen Xin, it still needs him to think about what this idea should be.


    While Chen Xin was thinking, several ground service technicians also found tools and began to dismantle the engine according to what Chen Xin said.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 430

    Several ground service technicians are all proficient. Although it is not an easy job to dismantle an engine, they still dismantled the whole engine together with the intake duct after wasting some effort.


    Although Chen Xin has seen the design drawing of Yun 9, there are still differences between the drawing and the real object. Some things can only be determined by seeing the real object with his own eyes, or knowing how to do it.


    After seeing the real object of the engine, Chen Xin also made his own ideas clear.


    According to Chen Xin''s idea, the way that can be completed in a week, while taking into account the cost and transformation efficiency, is of course to install an air filter on the intake duct, which is the most simple, practical and economical way.


    There is no need to make major changes to the aircraft, and at the same time, it does not require too much investment.


    This plan is also Chen Xin''s first choice. The new air filter has been arranged for people to do it, and what he is going to do now is to see if he can do some more articles on the plane.


    After all, if only the air filter is installed, the aircraft engine will still have a certain impact, resulting in a great impact on the performance of the aircraft.


    To avoid these effects, it is necessary to work hard on the engine and intake duct.


    Without seeing the real object, Chen Xin had no concept in his mind, and the system upgrade couldn''t work, so he had to work hard for these ground technicians to dismantle the engine directly.


    With the disassembled engine and the complete intake duct, Chen Xin already has inspiration and direction in his mind, so the next work is relatively simple.


    Having studied the structure of the intake duct, Chen Xin clearly knows that after the installation of the air filter, if you want to ensure that the engine can still have enough power, one is to increase the intake volume. As long as there is a balance between the engine demand, the air filter block and the total intake volume, it can meet the actual needs.


    The simplest way to increase the intake volume is to enlarge the intake duct.


    This is naturally within Chen Xin''s consideration, but it is not the final choice, because it is necessary to enlarge the intake duct, but there are still some design problems in simple enlargement, which is not a simple enlargement.


    Moreover, in addition to enlarging the intake duct, the total amount of air intake can be increased by improving the air intake mode and air filter structure, rather than hanging from a tree.


    According to Chen Xin''s plan, it is to install a row of air intakes at the front end of the wing without damaging the structure, so that air can enter the engine from the wing.


    After all, if the intake duct is not enough, open one more intake port to ensure the total intake.


    However, there are also many problems in this design. No one has ever tried to add air intakes to the wing. Whether it will affect the flight and lift of the aircraft, and whether it will damage the structural strength of the wing, are all things that need to be demonstrated in practice. It is not the case that Chen Xinyi pats his head and upgrades the system a little bit.


    So the safest way is to improve the original air inlet to improve its air intake effect and ensure the air intake.


    Of course, in addition to this short-term effective and low-cost way, there is another effective way, that is, electric compensation or directly changing the aircraft engine to electric.


    Electric compensation is Chen Xin''s working experience when he sold chemical equipment. At that time, Chen Xin sold air-cooled equipment, relying on water pressure to drive the equipment to run, so as to drive the fan to produce enough air to cool.


    But sometimes the water pressure can not meet the operation requirements of the equipment, a small motor will be installed on the equipment to provide power compensation to ensure that the equipment can meet the operation requirements as a whole.


    This approach is also applicable to engines. After all, cars have hybrid electric vehicles, and it''s not surprising that airplanes adopt the same approach.


    Moreover, now that we have isotope thermoelectric batteries and miniature nuclear reactors, we can even realize full electric drive when we are equipped with airplanes. Therefore, there are many ways to solve the problem of air intake in airplanes.


    Before Chen Xin asked the staff to do the air filter device is one of them, improving the intake duct is the second, adding electric compensation auxiliary to the aircraft is the third, and all electric transformation is the fourth.


    This is the transformation plan and scheme Chen Xin made after reading the design data of Yun 9 all night. The resources and time consumed by the four are in direct proportion to the increase. Adding air filter is the simplest, and all electric transformation is the most difficult.


    However, with isotope thermoelectric cells and miniature nuclear reactors, there is enough basis for all electric transformation.


    If the full power transformation is really carried out, in fact, for the country, it can completely change the operation mode of the existing aviation field, and even restore the smooth operation of aviation throughout the country.


    After all, the main reason that restricts the national aircraft flight is that there are too many suspended particles and dust in the air. If we use the traditional engine, we have to face the problem of engine damage caused by dust and particles entering the engine.


    As for whether the particles and dust suspended in the air will cause damage to the aircraft itself when the aircraft flies, this conclusion is affirmative.


    After all, the relative speed is so fast, no matter how insignificant the dust will cause wear on the surface of the aircraft, but this is inevitable, unless Chen Xinzhen installed an energy shield on the aircraft, it can resist this kind of wear and tear.However, as long as it does not encounter particularly large dust or particles, in theory, it will not cause too much damage to the aircraft.


    It''s just hard work. Every time the plane takes off and lands, it has to be maintained. Otherwise, it will still break quickly.


    Chen Xin is not ready to solve this problem, especially since he has just experienced the previous events, and has already understood that too much is better than too much.


    It''s still within the normal range to take out the transformation scheme of the air inlet duct and the new air filter, and the energy shield is beyond the scope of ordinary people''s cognition.


    Even if we really want to do it, we can''t do it right now. At least we should do it step by step, and we can''t do it until we point out the advanced technology.


    While thinking about this, Chen Xin certainly didn''t delay his business. He was also thinking about how to reform the aircraft with all electric drive.


    All electric drive is not only electric compensation, but also a major transformation of the aircraft, especially the engine part. The whole aircraft should be redesigned completely, and the wing of the aircraft is the same.


    After all, the engine and fuel tank are installed on the wing. If the aircraft is replaced by electric, the original engine and fuel tank must be discarded. But how to put the new electric equipment on the wing and how to design the new electric drive engine are all problems.


    And the most important thing is that the electric drive engine of the aircraft has never been, and never has been, such a high-power electric drive engine. Everything has to be designed from scratch.

 Chapter 431

    Seven days passed in a hurry, and the lights on the runway of the combat readiness airport were bright.


    The ground crew is seriously checking the runway, which has not been used for a long time. They need to check before takeoff to ensure that there is no foreign matter on the runway that affects the aircraft take-off and landing.


    The airport tower in the distance has also been lit up for a long time, and entered the state of use, and ushered in a large number of people to stay here, ready to watch the upcoming aircraft test flight.


    "Runway 1 has been checked and there is no foreign matter or ice. It is ready to take off." Soon the news came from the runway that the inspection had been completed.


    "Runway confirmed, please take off from runway one." After receiving the message, the wisdom of the tower said to the plane that had been pushed out of the hangar and was ready to take off through the walkie talkie.


    "Test aircraft received, taxiing into runway." Soon there was a reply from the testing machine.


    From the window of the airport tower, you can clearly see that an aircraft is slowly sliding from the hangar to the end of the runway, adjusting its position and preparing to take off.


    "Can you really fly?" The leader who came to watch the test flight inquired about the people around him and seemed worried.


    "You can rest assured that academician Chen is young, but the project he is responsible for has never had any problems." The staff beside the leader said in a hurry that although they blindly believed in Chen Xin''s suspicion, it was obviously impossible to pour cold water on him at this time.


    After all, who knows whether the leaders are really worried or ask casually?


    However, there are some hidden dangers in this flight test. Chen Xin has been able to complete the transformation plan and specific transformation of the aircraft in such a short time, but now he has to do the flight test, which makes people feel a little worried.


    In seven days, although Chen Xin did complete the transformation plan on time, and also completed the transformation of the aircraft used for the transformation experiment, and pushed it onto the runway to prepare for the test flight, the time was really too short.


    Under normal circumstances, the aircraft itself needs to go through a series of strict inspection and acceptance to ensure that the inspection is correct before it can really carry out flight test.


    But now it is only seven days since Chen Xin took over the task and has been pushed onto the runway.


    After Chen Xin completed the transformation, he had already organized people to carry out technical demonstration and various inspections. Theoretically speaking, there is no problem, but who can guarantee that there will be no problem after the plane flies?


    You should know that even if the aircraft has passed the technical demonstration and various inspections, there will still be all kinds of problems during the flight test. After all, no one knows what kind of situation the aircraft will encounter when it really flies into the sky. A little carelessness will lead to the destruction of the aircraft and the death of people.


    And that''s why test pilots are the most elite pilots, and aircraft test flight is still one of the most dangerous jobs in the world.


    If possible, the leaders will not let the valuable pilots take such risks. They will ask the technicians to conduct more detailed technical demonstration and inspection, and they will not just give Chen Xin seven days to get a result.


    However, time is really not enough, there is no surplus to be able to slowly.


    During the seven days when Chen Xin reconstructed the plane, the volcanic ash from the dopa volcano has already spread to Qiongzhou and Guangdong Province. Although the earthquake did not cause a tsunami because of the ice layer on the sea, a large number of ice layers cracked, and even some broken ice was pushed to the Shanghai coastline, making people feel the existence of the crisis.


    In addition, the most important thing is that a magnitude 3.5 earthquake occurred in Southwest China in the past seven days. Although the magnitude was not strong, it made everyone nervous.


    The earthquake may be just a very common geological activity, after all, the southwest region itself is in the earthquake prone zone.


    But what if? What if the eruption of DOPA volcano affected the seismic belt in Southwest China and made it active?


    No one dares to gamble on this possibility.


    What the country can do now is to prepare in time and do all the preparatory work that can be carried out in advance, so as to avoid being in a hurry when disaster may happen in the future.


    "What about Comrade Chen Xin? Won''t he come to see the test flight? " The leader''s line of sight turned for a while, and did not see Chen Xin''s figure in the tower.


    "Academician Chen is over there in the hangar. He said that he would make the final inspection before the plane takes off," the staff replied


    "I see." The leader nodded and said nothing more.


    At this time, the aircraft on the runway has also completed all the checks before take-off, ready for take-off.


    "Tower, this is the test plane. Request to take off." The pilot''s voice seemed a little nervous, but he still applied for takeoff with a firm voice.


    The commander of the tower looked at the leader and nodded. Then he said to the pilot, "test plane, this is the tower. Take off is allowed."


    With that, the commander seemed to hesitate for a moment, and for the first time said: "Bon voyage."


    Hearing this, the pilot was stunned for a moment, but he responded quickly: "thank you for your blessing, I''m about to take off."As the pilot''s voice dropped, the people in the tower saw that the plane, which had stopped at the end of the runway, began to slide forward and was accelerating.


    This time, everyone in the tower''s heart was pulled up, nervously looking at the first fixed wing aircraft to take off after the meteorite hit the blue star.


    As the aircraft speed faster and faster, and closer to the end of the runway, the nose finally lifted up, the whole aircraft roared up from the runway and rushed into the night sky.


    Seeing the successful take-off, everyone in the tower cheered and even clapped.


    Although it seems like a normal night flight, it means that human beings have once again printed their footprints in the sky.


    However, flying does not mean there is no problem. The situation on the ground is much better than that in the sky. Most of the particles and dust have dropped almost in the past year, but there are still a lot of suspended dust and particles in the sky.


    Especially above the stratosphere, because the original air flow is relatively stable, resulting in a large number of fine dust and particles suspended in the air for a long time, and will not fall in a short time.


    As a result, when the aircraft enters the stratosphere, the engine will inevitably inhale a lot of dust and particles due to the intake air, which will cause wear to the precision parts in the engine.


    Now, although Chen Xin has installed an air filter on the air intake duct of the aircraft, the specific effect can still only be known by flying to the sky and actually flying around.

 Chapter 432

    Chen Xin originally wanted to take off with the plane, so as to monitor the state of the plane in the whole process.


    However, neither the ground crew nor the staff could allow an academician to take part in such a dangerous test flight, so they stopped Chen Xin before he got on the plane.


    Although he was stopped, Chen Xin still wanted to follow up and see the state of the plane. After all, it was a plane he had transformed. Although the quality of the system was guaranteed, Chen Xin still wanted to see what happened after the plane arrived.


    And even if not on the plane, Chen Xin can also fly, not because not on the plane, will not be able to monitor the situation of the plane.


    Releasing nano molecules from the wrist watch, Chen Xin directly put on nano armor this time and switched it to flight mode.


    Although the iron man uniform in the movie looks really handsome, Chen Xin doesn''t like the flying posture with his hands close to his waist and his palms open.


    As a matter of fact, Chen Xin doesn''t like the flying posture of meimanzhong. Whether it''s iron man''s hands on his waist or Superman''s fist clenching, it''s OK to watch it in the movie, but in reality, it''s embarrassing and awkward.


    For Chen Xin, it doesn''t matter what kind of posture he uses. The power of flight comes from the plasma engine on the back of the power armor. The attitude control mainly depends on the jet ports of the legs of the armor and the vector jet ports of the engine itself. All these are controlled by the flight control system of the armor.


    So it doesn''t hurt what posture Chen Xin uses to fly. He just needs to tell his armor where to fly.


    In fact, Chen Xin flies from the ground with a posture of 60% body tilt, and flies rapidly to the plane ahead with the strong thrust of the plasma engine.


    In the air, the only thing he needs to pay attention to is not to swing his legs. On the contrary, there is no limit to his hands. Whether he sticks to both sides of his body, raises his fist, takes a weapon or simply takes something out to eat, for flight, the only thing affected is the overall aerodynamic shape of the armor, which will cause air resistance.


    And this, for Chen Xin''s nano armor, just need a "big fly brick" to solve.


    The thrust generated by the plasma engine on the back of the nano armor is no worse than the four engines of yun-9 that are flying in front of Chen Xin. What the nano armor engine needs to push is Chen Xin''s body, which is less than 200 Jin, but the four engines of yun-9 need to push at least dozens of tons, even if the cabin of yun-9 is empty We''re flying.


    By comparison, it doesn''t matter what posture Chen Xin uses to fly. As long as he doesn''t fold his arm, he has no problem.


    Moreover, if Chen Xin wants to, the flight speed of nano armor can break through the sound barrier at any time, easily reaching Mach 5, that is, five times the speed of sound, regardless of the human body''s bearing capacity.


    The maximum acceleration that human beings can bear is 8g, that is, 8 times of the acceleration of gravity, which limits the maximum flight speed of supersonic aircraft to about Mach 2, because beyond this speed, the pilot will have to bear more than 8g acceleration, causing a huge load on the pilot''s body.


    Although anti-G suit and other equipment can be used to reduce the impact of acceleration on pilots, even if the instantaneous overload is too large, it will still cause a series of problems such as human blood vessel rupture, eye congestion and so on.


    So for the sake of safety, although his nano armor can easily break through the sound barrier, Chen Xin did not.


    After all, the speed of yun-9 is not as fast as the speed of sound. The normal speed is enough for Chen Xin to catch up with the test plane. There is no need to break through the sound barrier.


    Chen Xin soon got close to the flying yun-9. Through the multi-functional visual display on the nano armored helmet, Chen Xin could clearly see the inconspicuous aircraft in the dim sky except for the navigation lights, and the huge heat emitted by its engine when it was working.


    The advantage of nano armor over ordinary armor lies in the fact that any tool or function needed can be modified temporarily. As long as there are nano molecules and design drawings stored in advance, the required modules can be changed at any time when needed.


    Naturally, Chen Xin did the same. After adjusting the lens and camera on his helmet, the image displayed in front of Chen Xin''s eyes suddenly changed.


    A lot of data suddenly appeared around the body shape of the whole yun-9, and many data are still changing with the flight of the aircraft.


    Naturally, this is the flight data of yun-9, and it also includes the changes of the airframe and the monitoring of the working condition of the engine.


    Some of these data come from the monitoring equipment used by Chen Xin in the transformation of the aircraft. After all, there are many instruments used to monitor the status of the aircraft in modern aircraft, so that the pilot can know the flight status of the aircraft at any time during the flight.


    This part of the data can be obtained by connecting with the plane''s flight computer. The other data is thanks to Chen Xin''s multifunctional camera on his helmet.


    Because you have already got the flight data of yun-9 under normal conditions, you only need to compare the two data to know whether the plane after the transformation is stable and normal.Judging from the current situation, there is no problem with the plane that has been modified by Chen Xin.


    For this aircraft, Chen Xin adopted two different transformation methods on four engines, two of which adopted the transformation method of adding an additional air inlet below the original air inlet and installing an air filter on the air inlet at the same time.


    In this way, the engine itself has not been changed. Even if the air inlet and the redesigned intake duct are installed with air filter, they can still provide enough air intake for the engine and guarantee the engine power.


    As for the other two engines, there are no air intakes, just air filters to ensure that the air inhaled by the engine is free of particles and dust.


    However, the power of the two engines did not decrease, because Chen Xin installed a small motor on the two engines to provide power compensation, so that the engine can still achieve the required output power under the condition of insufficient air intake.


    It''s not clear which of the two plans is better for the time being. The experimental yun-9 still needs to climb.


    Under normal circumstances, planes fly in the stratosphere, and yun-9 is no exception. Therefore, both the plane and Chen Xin, who monitors the data on one side, have to fly up a little bit until they reach the stratosphere.

 Chapter 433

    Stratosphere is one of the layers of the atmosphere, which is located above the troposphere and below the middle layer. Because it absorbs a lot of ultraviolet radiation, the temperature of this layer is cold in the bottom layer and hot in the upper layer.


    This is just opposite to the upper cold and lower heat in the troposphere, and it is precisely because of this that the stratosphere is relatively stable, and there is no conventional convective activity and so connected air flow.


    Because of this characteristic of stratosphere, it is also called stratosphere. The temperature and airflow are relatively stable, so it is an ideal place for aircraft flight.


    Most of the world''s civil aircraft are cruising in the stratosphere to avoid the changeable weather and airflow in the troposphere, so as to maintain flight stability.


    In the past, because of the stable air flow, lack of water vapor and no alternation of cold and heat in the stratosphere, this layer can be called cloudless. Once the plane flies to this height, it can only see the sea of clouds below, while there is only endless blue sky and strong sun that can burn people above.


    However, as soon as Chen Xin and Yun 9 took off at this height, the only thing he could see was that it was as dark as a strong sandstorm.


    Chen Xin used to work in the imperial capital of Yan state. At that time, it was the most serious haze problem in the imperial capital. Once, when Chen Xin went to work, the weather was extremely bad. He stood on the side of the road and could not see the other side nearby.


    If it wasn''t for a huge outdoor electronic screen shining in a shopping mall on the other side at that time, Chen Xinzhen thought there was nothing on the other side.


    And the stratosphere at this time, and Chen Xin''s memory of the extremely bad weather in the imperial capital.


    Not only that, the dust and particles all over the sky block the sunlight that should have been shining down. Looking up, it seems that the whole world is a yellow, just like the last moment of the day, the earth is about to enter the darkness, but the sun struggles to burn the last ray of light on the horizon.


    Although it is a long lost sunshine, it gives people the feeling that a world has come to an end, even the sun has burned out, and the whole world has turned into a desert.


    However, this is not waste soil, but at an altitude of 12000 meters.


    The visibility of Chen Xin''s line of sight does not exceed 200 meters. If the distance between Chen Xin and Yun 9 is not kept at less than 100 meters, he will even lose the trace of the plane.


    Even so, in this dusky world full of dust, the distance of 100 meters still blurs Yun 9''s figure.


    Because of the disturbance of the airflow, a yellow cover gradually appeared around the aircraft, which is the scene of dust flowing along with the airflow on the surface of the aircraft.


    This situation will obviously cause great impact and damage to the aircraft. Even if Chen Xin installed air filters on the aircraft engine, he will not last long in such an environment.


    Sure enough, it''s only a short time since the plane entered the stratosphere. In Chen Xin''s field of vision, all the data of the plane have begun to turn red. Especially for the engine, it''s obvious that the intake volume and power of the engine have been affected, and even the propeller blades have begun to vibrate.


    Seeing this situation, Chen Xin decisively connected the plane''s communication channel, and yelled to the pilot in the channel: "the plane''s state is affected by the dust, and it won''t last long. Lower the altitude immediately!"


    "Academician Chen? How do you know The pilot suddenly heard Chen Xin''s voice and was surprised. He wondered how Chen Xin knew the state of the plane.


    However, the various instruments on the plane also showed the problems encountered by the plane at this time. Many instruments have started to alarm. Before, the pilot wanted to test the limit of the plane under this state under pressure.


    But now Chen Xin ordered him to lower the altitude, and the pilot did not disobey his order. He pressed the lever and let the whole plane begin to lower the altitude.


    Chen Xin has been following the plane, watching it re-enter the troposphere, take off the lingering yellow "Ribbon" and be surrounded by darkness again. Then he yelled to the pilot through the communication channel: "open the tail hatch, I want to go in."


    "The hatch? Academician Chen, are you outside? How did you get here? " The pilot was completely shocked. When he was flying the plane for the first time, he heard someone tell him to open the cabin door and let people outside come in.


    This is a plane, not a car! No one ever said to open a door to let people in when a plane is flying in the sky.


    However, after repeated confirmation, Chen Xin still insisted that he open the door, and the pilot could only open the hatch of Yun 9 according to Chen Xin''s instructions.


    As a transport aircraft, the tail cabin of yun-9 can be opened, and it can be opened in flight for airdrop or parachute jump.


    But no matter how big the brain hole of the original designer was, I''m afraid I didn''t think that someone would be able to enter the plane in the sky through the open hatch.


    However, with flying nano armor, Chen Xin can really get into the plane through the open cabin door during the flight.


    Although it looks similar to the scene in the movie, Chen Xin did fly in and landed in the cabin of yun-9 when the hatch of yun-9 was opened.


    Several crew members in the cabin were surprised to see Chen Xin in nano armor. No one thought that someone would enter the plane on such an occasion.Seeing Chen Xin entering the plane, the crew quickly closed the hatch again.


    It''s not easy to open the cabin door at high altitude. The pressure difference inside and outside the cabin will cause pressure loss inside the cabin.


    "How many items have not been tested in this test flight?" Chen Xin opened the helmet''s mask and let the nano molecules that make up the helmet flow down. He showed his face and asked the crew.


    There are many test items in this flight test, and these crew members are responsible for these tests.


    "A lot of high-altitude flight tests have not been done. The plane just entered the stratosphere for a period of time, which is not enough." A crew member looked through the record board in his hand and reported to Chen Xin.


    As the crew of this test flight, they all met Chen Xin before taking off, and naturally knew this young and shameful academician.


    Chen Xin nodded and said to them, "in addition to the test that you have to fly to the stratosphere, do the other tests like this. Tell the pilots to keep flying at the altitude of the troposphere instead of rising to the stratosphere."


    "Yes, academician." The crew answered, but asked Chen Xin, "do you need to tell the academician on the ground about your coming up?"


    "Let them know." Chen Xin nodded, then went through the door inside the cabin and toward the cockpit.

 Chapter 434

    After all the tests in the sky, yun-9 finally returned to the combat readiness airport and was pushed into the hangar again after landing.


    Many problems have been exposed in this test. The plane not only needs to be inspected and maintained, but also needs to be repaired in many places.


    When the leader came to the hangar with a group of people, he was about to ask Chen Xin why he wanted to go up with the plane. However, he saw that he was floating in the air with the help of the flight ability of nano armor to check the propeller of the plane. He had to hold back the responsibility and asked Chen Xin about the plane.


    "Academician Chen, how was the flight test?" The leader raised his head and asked Chen Xin, who was floating in front of the propeller.


    Hearing the leader''s voice, Chen Xin turned his head and looked at him. Then he came down from the sky and said hello to him: "good leader, the flight test is good, but there are still many problems."


    "Can you be specific?" When the leaders heard Chen Xin say this, they couldn''t help being serious.


    "The flight condition of the aircraft in the troposphere is OK, but the environment above the stratosphere is too bad for the aircraft to adapt to this situation at present." Chen Xin explained to the leader, and took the leader to the bottom of the engine of the aircraft, and showed the air filter that had been removed by the ground service technician to the leader: "leader, please look here. Although this air filter can effectively prevent the dust from entering the engine, it also has serious dust accumulation because it blocks the dust from entering the engine.


    Because there are a lot of dust and particles in the stratosphere, the aircraft engine will inhale a lot of air during flight, which will cause dust accumulation in the air filter, and a lot of dust accumulation will affect the air filter effect, resulting in the decrease of aircraft engine power. ? "


    hearing Chen Xin say so, the leader''s face became a little dignified. He asked Chen Xin," is there any way to solve this problem? Can''t the plane fly normally now? ? "


    facing the leader''s question, Chen Xin replied:" at present, the environment is like this, we have no way to solve it, but if we want to make the aircraft fly normally, there are still ways.


    We can make the aircraft only fly below the stratosphere. If it doesn''t enter the stratosphere, the air environment in the troposphere is OK. The normal flight of the aircraft can be guaranteed only by air filtration.


    Of course, we can also make all electric aircraft, so as to ignore the impact of dust and particles on the aircraft engine. This is also the second transformation scheme I proposed, using the micro nuclear reactor as the power source of the aircraft, so as to use the electric engine to provide power for the aircraft. ?


    "electric aircraft? Is this really possible? " A staff member beside the leader asked Chen Xin.


    Chen Xin nodded and showed a drawing to the leader.


    "This is the electric aircraft I designed. It uses a 3 megawatt nuclear reactor as power to provide sufficient power for the four engines of the aircraft. "As Chen Xin said, he pointed out on the drawing:" I refer to the famous Osprey helicopter, which also adopts the tilting rotor design, but compared with the Osprey helicopter, the propeller of this aircraft is four, which can provide more lift for the aircraft. ? "


    " four propellers How does this look like a UAV? " The leader looked at the plane on the drawing and felt that the layout of the propeller was really like a UAV.


    Chen Xin nodded, did not hide what he was referring to, and answered positively: "I just refer to the propeller layout design of UAV. It can take off and land vertically like UAV, or take off and jump like Osprey helicopter. When in the air, the four propellers can provide both lift and thrust, which is enough for all kinds of complex rings It''s necessary to fly under the environment.


    Moreover, this design has one advantage over the original Osprey helicopter, that is, it can use two propellers on the front wing to provide lift vertically and two propellers on the rear wing to provide thrust horizontally.


    We don''t have to face many technical problems like the Osprey helicopter because of the change of propeller, although I have solved all these technical problems. "


    Hearing Chen Xin say such words, the leaders were deeply shocked.


    In seven days, Chen Xin not only completed the transformation of the original yun-9 transport plane to enable it to fly normally, but also completed the design of the new helicopter, which was beyond his imagination.


    Under normal circumstances, the design of an aircraft can only be completed in a few years at least. It took 20 years for the Federation to manufacture the Osprey helicopter!


    At this moment, the leader finally had an intuitive understanding of Chen Xin''s ability.


    "What''s the performance of this plane?" The leader calmed down, didn''t show his emotion on his face, but instead cared about the performance of the plane.


    "The length of the aircraft is 20 meters, the maximum wingspan is 16 meters, the height is 7 meters, the empty weight is 16 tons, the maximum take-off weight is 40 tons, the load is 20 tons, the maximum flight speed is 550 kmh, and the practical lift limit is 8000 meters. Because it is driven by nuclear power, its flight distance has no upper limit." Chen Xin introduced the performance of the aircraft in a rather proud tone, and said with pride: "the performance of the aircraft is slightly better than that of the Osprey helicopter, which can carry 12 fully armed special forces soldiers, or carry 2 tons of materials at the speed of 500kmh.Whether it''s used in combat, disaster relief, or material transportation, it''s perfectly competent. This is the best solution I can think of after referring to the current environmental conditions. After all, conventional engines of other aircraft always have to face the impact of dust in the air. "


    When Chen Xin said this, he also motioned to the leaders to have a look at the propeller of Yun 9.


    Following Chen Xin''s instructions, the leader was surprised to find that Yun 9''s propeller was full of scratches and wear marks, which almost covered the windward side of the whole plane.


    "If you just fly in the troposphere, it''s OK, but if the plane goes into the horizontal flow, a large number of particles and dust suspended in the air will cause great wear to the plane under the influence of the air flow. The faster the speed, the greater the wear.


    Therefore, in the current situation, the stratosphere is still a no fly zone. Unless the aircraft skin is made of higher strength materials, which are not afraid of wear and tear, and the engine can ignore the damage caused by dust, I do not recommend any aircraft to fly in the stratosphere. " Chen Xin looked at the leader and said to him solemnly.


    After listening to Chen Xin''s words, the leader looked at the scratch and damage on the surface of Yun 9. After thinking about it, he nodded his head seriously.

 Chapter 435

    Through the flight test of yun-9, the two transformation schemes proposed by Chen Xin have also been approved.


    Although the stratospheric situation still does not allow aircraft to fly, but at least there is Chen Xin''s proposed transformation scheme, which can allow aircraft to fly in the troposphere. For the current situation, it is a great good news.


    Although maintaining the aircraft in the troposphere will encounter very bad convective weather compared with the stratosphere, and will consume more fuel due to various conditions, it is better than not being able to fly or having to overhaul the whole aircraft once flying.


    One of the two ways to save money is to reform the air inlet of the aircraft. After all, if the electric drive compensation is added, the engine should be reformed, both in time and cost.


    Therefore, after some discussion and research, the high-rise building finally decided to adopt the method of reforming the intake duct.


    Moreover, this method has also been improved in the hands of researchers. It only needs to cut a hole under the original air inlet and connect the new inlet duct, and it does not need to redo the whole inlet duct.


    The final product looks like an additional plug-in, but from the effect, it is very practical.


    As for the electric drive compensation scheme for engine modification, although this scheme is very good, it has not been implemented in the end. It is only decided to modify one or two for the research of electric drive engine.


    After all, compared with the air filter transformation scheme, the nuclear power electric drive scheme is obviously more valuable and attractive.


    However, these studies were not handed over to Chen Xinji, but to several research institutes that originally studied aircraft engines. The design drawings of the new aircraft prepared by Chen Xinji were also handed over to the research department for research and trial production.


    This is not a requirement of the state, but Chen Xin offered not to be responsible for the development of the new aircraft.


    After all, this is a very time-consuming and laborious work, and he has done all the drawings well. As long as he makes the aircraft according to the drawings, he can make it.


    The work after that is nothing more than to adjust or improve various problems of the prototype, which requires professionals to spend a lot of time to complete. Indeed, Chen Xin does not need to do it himself.


    Even if he does it, it only needs one or two upgrades to solve all the problems.


    Of course, the state did not allow Chen Xin to be so idle, but entrusted him to develop more advanced new fighters.


    In today''s environment, of course, the country''s military strength has also been weakened.


    The army is OK. Although its mobility is limited, ordinary soldiers are still able to give full play to their combat capabilities. Although the attack is insufficient, it is still no problem to defend against the enemy''s attack.


    Especially after Chen Xin provided exoskeleton protective clothing, the military is mass producing this new equipment. At present, most of the main combat forces have been installed, which greatly improves the combat effectiveness of the army.


    Although there is no mechanical equipment, the individual combat ability is better than before the disaster, and it is enough to fight against any ground forces.


    Although in such an environment, neighboring countries do not have the ability to attack Yanguo, it does not mean that the army can relax its vigilance.


    Although the army still has the strength of the first World War, the Navy and the air force are about to be shaved off.


    The problem of the air force is mainly the problem of aircraft engines, whether it is jet or propeller aircraft, can not fly in the air filled with dust.


    However, thanks to Chen Xin''s new air filter and improvement scheme, as well as the gradual recovery of the environment and the gradual unsealing of the air force''s aircraft, the combat power has finally been restored to a certain extent, so as not to let the pilots who are more valuable than gold trained by heavy money be abandoned.


    But the problems facing the navy are much more serious.


    The rise of the coastline engulfed the Navy''s original ports and bases, which undoubtedly gave the Navy a heavy blow.


    Not to mention the damage caused by the global fire caused by the meteorite impact on the warships that can not be avoided. After losing the coastal port, the warships can not even find a suitable place to repair the damage.


    And then the temperature plummeted, the sea was frozen, so that all the warships lost their use.


    In the face of several meters of ice, even the nuclear powered aircraft carrier is difficult to play its role, and the professional icebreaker can not break the ice several meters thick.


    This makes the whole navy really a Marine Corps.


    Of course, Chen Xin knows something about this situation. Even if he doesn''t know, people in the military will tell him the news, and will not let him, who is most likely to solve the problem, not know the situation.


    But at present, what Chen Xin can solve is still the problem of Air Force aircraft. Although there is no way for Navy warships, under the current situation, the cost and time of moving warships are too large.


    Chen Xin doesn''t want to move those tens of thousands of tons of steel products for the time being, but it''s a good choice to help the air force design several new aircraft.


    Although the air force''s helicopters and some propeller aircraft have been able to gradually restore their flight capabilities, jet aircraft are still unable to fly.It is not only the problem of engine intake, but also the problem of dust and particles in the air when the aircraft is flying at supersonic speed.


    You know, even an ordinary civil aircraft can be hit by a bird, not to mention a supersonic fighter?


    Even now there are no birds in the sky, but those fine particles and dust can still cause great damage to the aircraft.


    This can be seen from the previous yun-9 test flight, but after flying in the stratosphere for a short time, the fuselage was covered with small scratches, even the propeller was damaged.


    In the face of this situation, the military and national high-level naturally hope to have an aircraft that can cope with the current situation.


    Originally, several domestic aircraft R & D institutions were competing for this R & D task, and they had begun to have some R & D intentions and ideas. However, Chen Xin could not bear to smash a mature Quad rotor aircraft directly in seven days, or tilt rotor like Osprey helicopter!


    This is the fastest and most advanced helicopter on Bluestar at present, but Chen Xin''s new aircraft is more advanced than the Osprey''s.


    The senior management has no way to ignore Chen Xin''s existence, and the military strongly recommends Chen Xin to carry out the research and development of new aircraft.


    In their opinion, Chen Xin will be able to complete this task in a short time, which is much faster than it takes several years or even decades for other R & D institutions to make achievements.

 Chapter 436

    Chen Xin was greatly interested in the research and development of the new aircraft.


    For him, it''s not limited to his ability to make a new plane.


    However, Chen Xin can''t be too open-minded. After all, he has to consider the actual production. Even if Chen Xin can make the X-Wing starfighter in Star Wars, the country can''t even make a lightsaber.


    This is the gap between the industrial system and the overall science and technology, which can not be made up by simply relying on Chen Xin''s opening.


    Therefore, even if Chen Xin wants to design a new fighter, he must also consider the country''s industrial production capacity and whether the new fighter can be built. In addition to design problems, there are also many factors such as cost and technology.


    This also led to Chen Xin can not use too exaggerated technology, it is better to design and Research on the basis of existing technology.


    For Chen Xin, it''s very easy to make the new aircraft design advanced. After all, there are so many sci-fi works, any one can be copied by the system.


    But to make the new aircraft more practical and less advanced It''s going to take some design.


    Fortunately, the place where Chen Xin is at this time is the temporary capital of the state of Yan. There are a lot of scientific research forces and relevant materials, and Chen Xin has the right to call these materials.


    Of course, Chen Xin can''t understand the specific scientific research materials, but if people sort out a catalogue and brief introduction of the technologies currently used by Yanguo in the field of aircraft manufacturing, Chen Xin can still find what he wants.


    For an airplane, the most important thing is of course the engine known as the heart.


    In those years, Yanguo had been spurted by people. The biggest problem was the engine performance and production R & D capability. It was once a great pity for Yanguo in the aviation field that there was no independently developed and reliable engine.


    Later, after the efforts of countless people, Yanguo finally made a breakthrough in this field, and the manufacturing and R & D of engine finally achieved fruitful results.


    However, for the new aircraft, Chen Xin does not intend to use the existing aircraft engine.


    Of course, there is no need to repeat the reasons. Chen Xin is optimistic about the electric propulsion system originally used in the aerospace field, also known as ion thruster.


    In short, the working fluid is electrolyzed into charged particles by electric energy, and then the thrust is obtained by accelerating the charged particles.


    This is also a common engine in science fiction works. It is usually used in spacecraft, and it is not considered to be used in the atmosphere.


    This is mainly because the thrust produced by the ion thruster is too small, or the power is too large.


    Ion thruster can accelerate charged particles to tens, hundreds of kilometers per second, or even higher. In this case, if a relatively large thrust is to be generated, the power required by ion thruster will be very large, and at the same time, it also needs a very large amount of energy to drive it.


    Taking the relatively mature technology on Bluestar as an example, if the power of the ion thruster is increased to 200kW, it can generate about 0.45kg thrust. Although it is not impressive in the atmosphere, if it is lifted into space, after getting rid of the influence of gravity, this thrust will be enough to push 2 tons of weight.


    Of course, this is the result of the original technology level of Bluestar.


    With the nuclear reactor technology currently mastered by Yanguo, it has been able to provide a micro reactor with a power of more than 10MW that can be installed on an aircraft, which is enough to provide abundant energy for the engine.


    What Chen Xin wants to do is to reduce the jet speed of the ion thruster, so as to increase its thrust.


    This is the same principle as a jet engine to reduce the jet speed and increase the engine thrust.


    Kinetic energy EK = MV ^ 22, momentum = MV, thrust is determined by momentum.


    For an aeroengine, the exhaust is the energy lost.


    In the case of constant momentum MV, reducing the exhaust speed can reduce the energy taken away by the exhaust and improve the efficiency.


    Similarly, keeping the momentum constant and reducing the exhaust speed requires a higher mass of working fluid, that is, more air is inhaled.


    So generally speaking, if an aeroengine wants to be efficient, it needs to drive a lot of air at low speed.


    However, although the principle of ion thruster is well understood, its demand for air, that is, working medium, is far lower than that of ordinary aero-engine.


    At present, the consumption of working medium per second of ion thruster is milligram level, and the thrust generated is 0.1N level. If this value is amplified to meet the thrust requirements of jet fighter, the consumption of working medium is still not worth mentioning.


    Taking the Taihang engine independently developed by Yanguo as an example, its thrust can reach 13.5 tons. If converted into cattle, it is 132300 cattle, and the corresponding consumption of working fluid is about 0.13 kg per second.


    The consumption of this working medium is absolutely not large. Similarly, taking Taihang engine as an example, its air intake is 118 kgsec, which is almost 1000 times that of ion thruster.Therefore, under the premise of using air as working fluid, the air intake required by ion engine is quite insignificant, even similar to that of ordinary household car.


    As for the problem of restricting the power of ion thrusters in the atmosphere, it is no longer a problem in the face of the abundant power provided by small nuclear reactors.


    To solve the problem of engine, for an aircraft, the rest is nothing more than aerodynamic layout, structural design and other details, and these details can be solved by the classic physical means of big flying brick.


    As long as the power is enough, no matter how bad the aerodynamic layout and structural design can fly, as long as it does not fall apart.


    Of course, Chen Xin hasn''t been so crazy that he plans to design the shape of the plane.


    But as a non professional, he considered more about the appearance of handsome, rather than rationality.


    Although according to a law of causality, the more beautiful the appearance is, the more advanced the technology is, but for the ordinary aircraft designer, the appearance should accommodate the technology after all.


    But for Chen Xin With systems in place, he can also achieve supersonic speed even if he builds a high-speed aircraft. Therefore, in terms of aircraft shape design, he can focus more on appearance than technology.


    After some brain holes and referring to the existing science fiction works, Chen Xin''s final design looks more like a space fighter than a fighter used in the atmosphere. Although the angular one is very handsome, it is not mellow at all.


    And the most important thing is that two of the three propellers Chen Xin installed on the aircraft are installed on the wings, which is quite different from the design and layout of the existing fighters.

 Chapter 437

    The new aircraft looks more like an armed helicopter, with three ion thrusters installed on its tail and wing, providing the aircraft with strong power up to Mach 3.


    It is also because of such a strong thrust that the pilot of a new aircraft must wear a special anti-G suit similar to a spacesuit to withstand it. Otherwise, the instant overload acceleration during maneuver will endanger the pilot''s life.


    This kind of three engine design is very rare in fighter planes. Except for some prototypes with big brain holes or models in science fiction, this is the first time that a model with three engines has appeared.


    Because of its strong power, Chen Xin didn''t think much about the aerodynamic layout, but he had a systematic optimization. Although the plane looked a little square, it still had a good aerodynamic shape, so it didn''t really have a lot of power.


    In addition, Chen Xin also takes into account the needs of radar stealth, so it will appear angular and not so round. But in front of the radar, the reflection area of the whole aircraft is not as good as a piece of A4 paper.


    The main power source of the aircraft is a 25MW micro nuclear reactor, which is installed in the belly of the aircraft to facilitate maintenance and repair, and to directly abandon the reactor in case of accident.


    Because the demand of ion thruster for working fluid is not large, Chen Xin only opened a row of air inlets along the wing.


    The flat air inlet can not only ensure the air intake, but also play a certain role in blocking the dust and particles, and can also blow away the dust blocked by the air inlet grille under the action of air flow, so as not to cause the air inlet blockage due to ash deposition.


    The cockpit is a standard single cockpit, and the highly integrated intelligent control system is enough to ensure that the pilot can easily control the aircraft and perform various tasks.


    In addition to the installation of nuclear reactors, the belly of the aircraft is also the main weapon carrying area. The four integrated weapon loading points can carry 16 missiles of various types, and can be put into the belly of the aircraft for secondary automatic loading when it is not in combat.


    At present, no fighter can do this. All fighters must be loaded before they set out to carry out the mission. The ground service will hang the missiles on the mounting points. No aircraft can load itself when it is flying in the sky.


    On the one hand, the aircraft''s take-off weight is limited, so it can''t carry so many missiles. On the other hand, the fuselage space is limited, so the automatic loading mechanism and the missile itself need to occupy a lot of space. In the case of limited aircraft space, there is no way to carry so many things.


    However, due to the use of ion thrusters, the new aircraft does not need to insert a huge fuel tank into the fuselage, nor does it need to install an engine much larger than the ion thruster, so it naturally has more load and space for installing other things.


    Although this set of automatic loading system can only complete one loading, it has been greatly strengthened for fighter, which is enough to enhance the combat capability of fighter more than twice and make it play a greater role in air combat.


    Moreover, Chen Xin also designed another mode for the new aircraft, that is, instead of carrying secondary loading missiles and automatic loading mechanism, it will be replaced by a wheeled pylon, carrying eight bombs for ground bombing, and turning into a type of aircraft that can carry out ground operations.


    In addition, under the nose of the fighter, Chen Xin also designed a magnetic rail gun for the fighter. Relying on the strong power provided by the nuclear reactor, the power of the magnetic rail gun is far more powerful than any aircraft gun currently equipped by Yanguo air force, and the ammunition load is far more powerful.


    As for another important avionics system on the plane, Chen Xin didn''t make any new things. He just upgraded the avionics currently used by Yanguo air force to a state that can be better integrated into the new aircraft.


    Nevertheless, the electronic countermeasure capability of the new aircraft is still excellent enough to easily confront the fighters of any country in the world.


    It can be said that the new aircraft is a versatile fighter with excellent performance. It is perfectly competent in air combat, ground attack, electronic countermeasures and air reconnaissance.


    After the design of the aircraft, it is natural to make it.


    As the chief designer of the new aircraft, Chen Xin is naturally responsible for the relevant work in this regard.


    The design drawings were sent to the relevant production units, and various parts were quickly produced and sent to Chen Xin with detailed drawings and investment regardless of cost.


    Although Chen Xin can use nano armor to turn into various processing tools to build the aircraft himself, considering that the aircraft needs mass production, Chen Xin still leaves the task of manufacturing parts to others.


    In this way, when the country needs to mass produce the aircraft in the future, the production units of these parts also have relevant experience, and no longer need to spend time on technical research and production line adjustment.


    The final assembly of the aircraft is a very complicated work. Fortunately, the combat readiness airport where Chen Xin is located has the conditions to assemble the aircraft, and the ground service technicians are at least experienced. It took Chen Xin a week to complete the bare metal assembly of the new aircraft.


    The assembled bare machine didn''t even paint. The metal skin of the whole plane was exposed in the primary metal color, which looked rough.In addition, the position of the aircraft''s nose seems to be missing due to the fact that the avionics and magnetic railguns are not installed.


    However, the aircraft is different from other aircraft''s strong lines, as well as the unique three hair styling and slender fuselage, which make the aircraft exude a unique aesthetic feeling.


    "Academician, the plane has been assembled, but the avionics system and the magnetic rail gun have not been delivered from the factory, and we can''t do the painting of the fuselage here." A technician stood beside Chen Xin and reported the assembly of the plane to him.


    For the lack of avionics and machine guns, Chen Xin clearly nodded, which was in his expectation.


    "Avionics and machine guns are not in a hurry. It''s difficult to manufacture these two parts. It''s understandable that the construction period is a little slower. First, install the fairing of avionics." Chen Xin asked casually while checking the status of the plane: "where is the painting going to be completed? Is the pilot ready for the test flight? What about the pilot''s anti-G suit? "


    "The pilot has been selected and will come to receive relevant operation and driving training tomorrow. The anti-G suit has been inquired before, and the reply given by the manufacturer is that it will be completed within three days." When the technician heard Chen Xin''s question, he turned over the record in his hand and quickly gave the answer: "as for spray painting, we have contacted the spray painting factory in Jincheng and they will finish the spray painting work."

 Chapter 438

    It''s still the runway 1 where Yun 9 was tested before, but this time at the end of the runway is a prototype of a new fighter designed and manufactured by Chen Xin.


    At this time, the plane is different from when Chen Xin saw it. Not only the avionics system and the magnetic rail gun of the nose have been installed, but also the whole plane has been painted.


    At the moment, it quietly stops at the end of the airport runway. It looks like a silent ghost, fully integrated into the darkness. Only a little light from the navigation lights can confirm its existence.


    The cockpit of this aircraft is completely different from the traditional transparent cockpit. The canopy is a metal outer layer connected with the avionics fairing of the nose. The interior is a display screen composed of several high-definition LCD screens, and the exterior high-definition cameras provide images for it.


    The pilot in the cockpit is not used to looking at the display screen around him.


    As an experienced pilot and a test pilot, there are a lot of airplanes flying by. The habit brought by the traditional transparent cockpit is hard to change for a while.


    However, although not very used to, but the pilot quickly found the benefits of LCD.


    If it is a traditional transparent cockpit, there is no light in the cockpit at night. Some of it is just a very weak luminous display on the instrument panel, so that you can''t see the reading clearly.


    What''s more, the sight is basically dark. Most of the operations are either guided by night vision devices or electronic systems, which can''t be confirmed by eyes.


    This is a very technical test for pilots, because when you fly up, the top and bottom are black, it is easy to lose the judgment ability, leading to the aircraft lost.


    But now, a large number of auxiliary displays on the LCD screen can not only help you judge the situation, but also bring intelligent high-definition display, which is much clearer than the pictures taken by naked eyes and night vision devices in the past.


    Even if necessary, the whole picture can be switched to day mode, that is, night can be turned into day through artificial rendering.


    Of course, this mode will take up a lot of onboard computer resources, and pilots will not turn it on unless necessary.


    After checking the systems manually, the pilot sent a signal to the tower to start the test flight.


    Although I have spent a lot of time to learn how to operate the new aircraft and how to use the new equipment on the aircraft, it is a new aircraft that is totally different from the previous one. The pilot is still a little nervous and sweaty.


    "Mocking wind, this is the tower. It''s clear when you run. You can take off." Just as the pilot nervously held the joystick and waited, the sound of the tower came from the headphones.


    "Jeer at the wind, ready to take off!" The pilot took a deep breath, grasped the joystick and began to steer the plane forward.


    The new aircraft was named mocking wind, named after the third son of the ninth son of Long Sheng, meaning that mocking wind was dangerous in his life.


    According to Chen Xin''s design, the three ion thrusters can flip the nozzle to allow the aircraft to obtain vertical lift and achieve vertical take-off and landing.


    But for the first test flight, we all chose the more stable ski jump takeoff instead of the vertical takeoff.


    With the pilot''s operation, the plane began to slide forward, and the speed became faster and faster. The strong sense of pushing back even pressed the pilot on the seat.


    But under the effect of the new anti-G suit, the pilot did not feel any pressure.


    With the acceleration of the aircraft, as soon as the pilot pulls the nose, the aircraft will jump into the air very light, light is not like a 20 ton aircraft, but like a swallow.


    "It''s so beautiful!" Inside the tower, watching the plane fly smoothly, everyone clapped their hands.


    Although we cheered in the same way in the run-9 test before, we still applauded for Chen Xin this time.


    A new fighter can complete the process from design to flight test in such a short time. Chen Xin''s "ability and level" has deeply convinced these people.


    However, Chen Xin just shook his head modestly. He didn''t get lost in these compliments. He turned to the commander in charge of air traffic control and asked, "did the two J20 take off?"


    "Two J20 simulated enemy aircraft have taken off from Jincheng airport and are expected to arrive at the scheduled operational airspace in 30 minutes." The commander took a look at the display screen in front of him and replied to Chen Xin.


    Chen Xin nodded and said to the commander, "let the jeer wind retract the reflection angle and test the effect of radar stealth."


    "Mocking wind, this is the tower. I want you to put away your reflection angle and enter stealth mode." The commander repeated Chen Xin''s instructions to the mocking pilot.


    In order to test the performance of the new fighter, Chen Xinli rejected the public opinion and applied for two J20 to carry out simulated air combat exercises before the new fighter''s flight test.


    After some discussion, the military passed Chen Xin''s application, transferred two j20s to him, and temporarily modified them to ensure that the plane could take off.However, in order to protect the aircraft, the three fighters did not fly high, but maintained the altitude below 8000 meters.


    According to the preset, mocking wind will approach the airspace where the J20 is in stealth mode and try to break through the interception of the two j20s. This breakthrough of course includes the option of mocking wind "shooting down" the two j20s.


    Although mocking wind, as a test aircraft, does not carry ammunition, and J20 does not carry live ammunition, as long as radar irradiation and locking are completed, it means that the aircraft has been shot down.


    After all, in modern air combat, being locked in is basically the same as being unable to escape.


    However, before the exercise started, there was a small problem on the side of mocking wind.


    Because when the mocking wind''s pilot retracted the reflection angle according to the command, the whole plane disappeared from all the radars.


    This caused a little commotion in the tower. The commander switched different radar bands, but there was no trace of mocking wind. If the communication had not been maintained, people would have thought that the new fighter had crashed.


    But the result is exciting, because if all our radars can''t find the wind, it undoubtedly shows that the stealth performance of the wind is excellent.


    "Academician Chen, is mocking wind so stealthy?" An air force officer who came to watch the exercise asked Chen Xin.


    "I''m not surprised by the result of the special coating on the shape." Chen Xin could only smile a little at this.

 Chapter 439

    On a plane taking off from Chongqing City, Chen Xin looked down at the city under his feet from the porthole of the plane. His face was in a trance.


    In recent months, he has been staying in Chongqing, dealing with the transformation of yun-9 and the research and development of mocking wind fighter. Now that everything is done, he can finally go home.


    In the past few months, yun-9''s transformation program has been widely promoted. At present, in addition to yun-9, several propeller aircraft have been able to return to the sky, re establishing Yanguo''s aviation network, providing important help for the communication and circulation between various regions.


    As for the mocking wind fighter, in the previous air combat exercises, mocking wind, which has excellent stealth ability, not only successfully broke through the blockade of two J20, but also successfully achieved radar irradiation and locking before J20 found itself, showing excellent air combat ability.


    This makes the air force very satisfied with the performance of mocking wind, and it is eager to carry out mass production immediately, and then equip the whole army.


    But this was not immediately implemented.


    On the one hand, the country''s main energy and strength need to be used to deal with the possible geological disasters in Southwest China, which can not be invested in the manufacture of new aircraft on a large scale.


    On the other hand, there are still some unsatisfactory aspects in the actual flight test of the mocking wind fighter, which need to be modified in detail.


    As for the plane, there are still some defects, which Chen Xin expected, but also some accidents.


    It is expected that this aircraft is largely from his brain and imagination, and the system is to ensure the realization of his imagination, so that the aircraft can really be realized. Naturally, there are some designs that Chen Xin wants, but which are not necessarily reasonable in practical application.


    In addition, Chen Xin also made some adjustments to the aircraft itself in order to enable the country to produce it, which made some problems more prominent.


    Of course, this is just to say that there are some imperfections in the design of the aircraft, not that the design of the aircraft has failed or failed.


    Moreover, all parts of the aircraft are distributed to manufacturing factories all over the country. Although they are all made in strict accordance with the requirements of the drawings, there will still be a little error, which needs to be adjusted and run in.


    So even if Chen Xin has left Chongqing, he is still responsible for the follow-up improvement work of mocking wind, and the whole project is also brought back by him.


    Even mocking wind''s prototype plane is flying with Chen Xin''s plane to the city where Chen Xin''s home is.


    Because of the re establishment of the aviation network, airports and related aviation facilities in various places are also being restored. Although civil aviation can not be restored at present, official and military aircraft can at least fly again, and these aviation facilities are also being used again.


    Chen Xin''s city has built an airport before, but the whole airport has been buried in thick snow. It takes time and effort to dig it out.


    However, now that the aviation network is restored, the airport here also has to undertake certain aircraft take-off and landing tasks. It is impossible if the airport is not restored, so the municipal government has adopted the method of building a temporary airport in the snow, which has finally restored the operation here.


    Although it is a temporary airport, it also meets the standard of a wartime runway. Both Chen Xin''s plane and Chuifeng can land.


    However, Chuifeng did not follow Chen Xin''s plane to land at the airport. Instead, he took off and landed at the completed scientific research base in a vertical way. Only Chen Xin''s plane landed at the airport.


    After getting off the plane, Chen Xin felt as if he was separated from the rest of the world. This is not only because after the disaster caused by the meteorite impact, he once again enjoyed the treatment of taking a real plane, but also because he had been to the airport several times in the past.


    The airport in Chen Xin''s city is a new airport, which has not been built or put into use for several years, so that Chen Xin still remembers what it looked like when he came to the airport last time.


    However, the new airport has now been submerged by snow. After all, it is not a big airport. It is just a small terminal and a runway. Now it has been buried under more than ten meters of snow, revealing only the faintly recognizable station name on the top of the terminal and the tower not completely buried by snow.


    However, since the end of the world, there have been so many things like this. Even Chen Xin can hardly have more feelings. He just shook his head a little, and then this feeling came out of his mind.


    On the special bus that had been waiting for a long time, Chen Xin returned to his refuge after a few months.


    In addition to the shelter, the ecological dome and scientific research base have been completed, and the geothermal power plant has also been completed. Even the planned greenhouse is ready for agricultural planting at any time.


    The barracks of the special forces were obviously reinforced, from the temporary camp which was originally composed of shelter and prefabricated houses to the semi permanent barracks.


    It''s just that before Chen Xin came back, all the facilities here, except the barracks, had not completed the final acceptance and put into use.


    Now that Chen Xin is back, naturally all kinds of acceptance work are on his desk.


    Fortunately, these things have been overstocked for several months, so there''s no need to rush for a while. Chen Xin just knows what things need to be dealt with, and then he''s ready to take a hot spring first to ease his spirits.As for the completed scientific research base, ecological dome and other facilities, according to Chen Xin''s original plan, they will be upgraded together with the refuge.


    Under the great power of the system, no matter what problems existed in the previous construction or what dissatisfied Chen Xin, it will become what Chen Xin imagined and needed in the later upgrading process.


    So for Chen Xin, the acceptance is just a walk through to let him know the functions and features of these facilities and avoid erasing them when upgrading.


    The survival required for system upgrading has quietly broken through seven figures in Chen Xin''s savings in recent months, which is enough for Chen Xin''s next extravagance.


    After clearing all this, Chen Xin naturally has no pressure and can rest assured to lie in his own hot spring bath and enjoy the relaxation and relaxation brought by the warm spring water.


    However, just as Chen Xin relaxed his nerves, closed his eyes and leaned against the hot spring pool to have a rest, the door of the bathroom was opened.


    The sound of two people''s footsteps sounded behind Chen Xin. At the same time, there was the sound of taking off clothes.


    Chen Xin did not open his eyes, but helplessly pinched his nose.


    Can enter the bathroom when oneself bubble bath, or two people come together, besides Qin LAN and Mo Qingyan, who else can have?


    Pity my waist! Chen Xin sighed helplessly.

 Chapter 440

    "Academician, you don''t look very well. Did you have a rest last night?" A staff member looked at some thick black circles on Chen Xin''s face and asked him with concern.


    Chen Xin shook his head, coughed, and then said, "nothing. It was a little late last night. It''s not in the way. Go on."


    "Yes, academician." Hearing Chen Xin say so, the staff had to nod their heads and continue to introduce Chen Xin: "at present, the whole ecological dome adopts drip irrigation, and the main water sources are extracted groundwater, snow water melting and recycled water recycling.


    The groundwater is mainly used to meet the domestic water and experimental consumption of the whole base, and the melted snow water will be used as a supplement after purification.


    In addition, we have also built a large-scale water recycling treatment device. The domestic sewage generated by the whole research base will be concentrated in the treatment device for treatment, and the treated reclaimed water will be used for crop irrigation


    Listening to the introduction of the staff, Chen Xin showed a satisfied expression on his face.


    Water is the source of life. Since ecological research is to be carried out here, the use of water is indispensable. If water supply can not be guaranteed, ecological research will be impossible.


    However, Chen Xin was still concerned and asked, "have you ever considered the problem of groundwater level decline when pumping groundwater?"


    "We have taken this into consideration. Now the weather is so bad that it is difficult to replenish the groundwater. So we are considering recycling the water vapor evaporated by plants and concentrating it to replenish the groundwater. But at present, this technology is still in the tentative stage, and the specific implementation can not be achieved." The staff member was somewhat ashamed when he said that, but he hastened to add: "however, this will be our research topic in the next stage. Once a breakthrough is made, the problem of groundwater compensation can be solved."


    Chen Xin can not deny the staff''s supplement.


    Other people are not him. Research can''t make a breakthrough by clapping their heads. Although the staff said that it would be the next stage of research, we can tell from this sentence that there is no sign of a breakthrough in research.


    Of course, this idea is very good, but with the progress of ordinary scientific research projects, it is too slow to achieve this goal.


    Besides, it is only possible to collect water vapor from plants in a closed greenhouse. For a large ecological dome, it can


    Thinking of this, Chen Xin suddenly raised his head and looked at the dome above his head, which was made up of glass and metal supports. An idea suddenly came into his mind.


    "You said, if the dome is modified to have the function of condensation and collection, can it recover the water vapor in the air?" Chen Xin looked at the staff and asked him what he thought.


    After hearing Chen Xin''s question, the staff quickly thought about it in their mind, nodded and said: "theoretically, it can be realized, but it needs to transform the whole dome. There is no problem in applying this design before construction. Now, it is a big and wasteful project."


    Of course, Chen Xin knows that the amount of reconstruction work is huge, but for him, it is equal to nothing.


    After understanding that this transformation method is feasible, Chen Xin also took out his notebook and recorded this one in the notebook, which he used when he was ready to upgrade later.


    According to Chen Xin''s expectation, the next upgrade will include the ecological dome, greenhouse, geothermal power plant, military camp, and his own shelter. Now of course, we need to understand all aspects of the situation clearly, and we need to record any feasible upgrade projects.


    It''s just the first time that the system has been upgraded on such a large scale. Chen Xin can''t help but feel uneasy. He doesn''t know how the system will solve the cognitive problems caused by the instant upgrade to ordinary people.


    If Chen Xin is the only one to complete such a large amount of work, it is obviously exaggerating. Is it to change the memory or cognition of the construction team?


    Chen Xin turned around the idea in his head, but the construction team had already left after the construction and did not stay nearby.


    However, this problem has not bothered Chen Xin. In his opinion, no matter what excuses the system shows, as long as the problem can be solved, there will be no problem.


    Even if the scope of this upgrade is too large, beyond the scope where the concept of the system can be vague, leading to the exposure of the system, it is acceptable for Chen Xin.


    After all, in terms of his current status, status and importance to the country, even if he only relies on the system to have the current ability, it will still not change his importance and strategic significance to the country.


    Because whether Chen Xin''s ability comes from himself or from the system, it is his ability. For the country, as long as Chen Xin continues to contribute to the country, both are the same thing.


    So Chen Xin doesn''t have anything to say now, and he doesn''t think about this thing that doesn''t mean much to him. Instead, he puts his energy on the idea of how to upgrade everything together.


    Simple upgrade is naturally simple, but just like the water vapor recovery function added just now, Chen Xin found many things that can be adjusted in detail when he walked around the whole scientific research base.For example, although the geothermal power plant is built according to the idea of energy tower proposed by Chen Xin before, in Chen Xin''s eyes, it still has room for improvement and upgrading. While improving the heat energy conversion efficiency, it also improves the energy utilization efficiency and reduces waste.


    The barracks of the special forces are equipped with shelter and movable board houses. Although the accommodation conditions are not bad, Chen Xin can upgrade them to barracks similar to those in science fiction works to make the soldiers'' accommodation conditions better.


    At the same time, it can also extend the defense system to the whole scientific research base and build an automatic defense network.


    In addition, the plan to change the structure of the refuge into a circular multi-storey layout was also made before, which should be adjusted and changed in the process of upgrading.


    While recording what he needed to modify, Chen Xin and his staff went to the underground of the ecological dome, where he used to research ordnance equipment. The mocking wind fighter that came back with Chen Xin was also parked here. At this time, several ground service technicians and researchers were surrounding it, doing inspection.


    Seeing this scene, Chen Xin knocked on his forehead and added another item to his notebook. This ordnance equipment research laboratory should at least have the ability to assemble vehicles such as airplanes and tanks. Otherwise, it would be too troublesome to try out a tank or an airplane and assemble it from other places.


    In addition to the general assembly capacity, should we build a machining center so that it can manufacture precision parts?

 Chapter 441

    If someone can see the upgrading scene of the scientific research base, then in his line of sight, he will see a green light column rising up, even soaring into the sky.


    At this time, the whole scientific research base is enveloped in the glory of green upgrading. Although there is no big change in appearance, there are many changes in details inside.


    For example, for Chen Xin, the most intuitive feeling is that the room he is in has changed from a square to a fan, and the original high and low bed in the room has changed into a double bed, and even three people can spread out.


    The soft clothes in the room have also changed, from the cold color of more recent future feeling to the warm color of more like a home, adding the warmth of several families.


    Moreover, the bathroom in the room has changed from only one shower room to a real bathroom and toilet with a series of facilities such as a washstand and a bathtub.


    These changes come from the drawings that Chen Xin had designed before. The whole refuge has changed from the original two-story square structure into a multi-storey cylindrical structure. The overall structure is more stable and the space utilization rate is also higher.


    Satisfied with the upgraded room, Chen Xin got up from the sofa and walked towards the door.


    The intelligent door senses Chen Xin''s body and opens automatically, revealing the clean, carpeted and brightly lit corridor outside.


    These are brought about by the upgrading, not only the upgrading of the level of science and technology, but also the comfort of living from the details.


    Stepping on the soft carpet along the corridor to the central elevator, Chen Xin pressed the button, and soon the elevator came up.


    Move the elevator from the corner of the original shelter to the center of the original column, which can save space. At the same time, other equipment that needs to run through the whole shelter can also be placed in the center, so that each floor of the shelter will not be occupied by space, so as to enhance the spacious feeling of each floor in use, and not feel that the space is narrow and underground.


    The elevator door opens and Chen Xin walks into the elevator, surrounded by dynamic landscape paintings.


    This is also one of the changes added in this upgrade, which comes from Mo Qingxin''s proposal.


    She felt that people lived underground for a long time, and it was dark outside. After a long time, people would be depressed. So when Chen Xin asked her what to add to the reconstruction of the refuge, she said that she hoped to see the scenery before the disaster.


    So after the upgrade, Chen Xin added an electronic window in each room of the shelter, which can play the scenery before the disaster or the picture of a city 24 hours a day. The same change has been made in the elevator, except that the four walls in the elevator are all electronic displays, which can enjoy the scenery 360 ¡ã without dead angle.


    It has to be said that once beautiful scenery can really bring physical and mental pleasure. If people have been depressed for too long in this disaster environment, they may even indulge in it.


    Of course, this has no effect on Chen Xin. It''s not that he is resistant enough or that he doesn''t have any trouble with it in his heart. It''s that Chen Xin has prepared for himself a holographic image room with holographic image projection, sound and smell simulation, and even air flow, light, temperature and other changes that can be fully simulated.


    There you can not only enjoy the scenery of the past, but also make people really immerse themselves, as if back to the past.


    So just a few dynamic landscape paintings in the elevator are not very attractive to Chen Xin.


    Taking the elevator to the top floor of the shelter, Chen Xin stepped out of the elevator, crossed the corridor and came to the gate. After a slight pause, he opened the heavy door.


    The gate is still the same as before, and Chen Xin has not made any structural changes to it, but the internal material and protection performance have been greatly improved in the upgrade. At least now, even the missile is hard to burst, especially Chen Xin has installed the energy shield on the gate.


    As for the original machine gun defense, Chen Xin did not upgrade the 12.7mm Gatling machine gun. After all, it is enough to be used as a defensive weapon.


    After all, if someone can break through the front heavily guarded scientific research base and kill all the way to his refuge, even if he upgrades the machine gun at the door to a howitzer, it won''t be very effective. Unless two 40K world knight titans are placed at the door, this kind of enemy can''t be stopped by automatic defense weapons alone.


    After going out of the gate, Chen Xin did not close the gate behind him, because there is a closed corridor connecting the ecological dome at the gate of his refuge.


    So even if Chen Xin doesn''t close the gate, it won''t have any impact on the shelter. Moreover, if someone comes to him later, it''s very troublesome to wait for the gate to open every time.


    Walking along the road in the dome, the temperature of the whole ecological dome is maintained at about 20 ¡æ, and the main source of heat supply is the heating hub standing in the center of the dome.


    The heat supply hub is connected with the energy tower of the geothermal power plant through pipes. After the first utilization of the geothermal power plant, the hot water will be transported here by pipes for the second round of heat dissipation, so as to provide heat for the whole ecological dome.Because there are no plants planted in the ecological dome, it is relatively open, but the water circulation system is still working well.


    There are several recycling water tanks around the heating hub, which are connected with the surrounding supporting columns and the top metal supporting structure of the dome. The dome that has been modified in the upgrading process can effectively recover the water vapor in the air, and then collect the water droplets bit by bit through the hollow pipes in the top metal supporting.


    These collected water droplets will eventually flow along the sink to the circular reservoir under the heating hub. The reservoir and the heating hub are made into a park like pool, but in fact its main function is to provide water vapor evaporation, so as to avoid the air becoming too dry because the heating hub is heating all the time.


    Around the heating hub is the reserved ecological area, and several annular planting slots have been put in place, just waiting for plants to be planted.


    As for the seeds of plants, there is no need for Chen Xin to worry about this. The relevant seeds have been mobilized and will be sent soon.


    Apart from the central ecological area, there are office areas and experimental areas around. Everything is divided according to the previous planning. The upgrading of the ecological dome mainly focuses on improving the ecological circulation capacity of the dome itself and the scientific and technological level of the laboratory, and there is no structural change.


    Looking at all this with satisfaction, Chen Xin came to the underground ordnance equipment test area through the elevator, intending to see the situation of mocking wind.

 Chapter 442

    At this time, the position of the fan belly was turned on, and several researchers were talking about the automatic loading device in the capsule.


    Obviously, the massive upgrading process just now does not exist for these people.


    Chen Xin did not deliberately ask anything, but walked to the side of the plane, these researchers stopped the discussion and said hello to Chen Xin one after another.


    Without waiting for Chen Xin to ask, one of the researchers took the initiative to say to Chen Xin, "academician, we were just discussing this set of automatic loading system. This is designed by you. Do you think it can be applied to other aircraft?"


    "Applied to other aircraft? Why do you think so? " Chen Xin looked at the researcher who asked the question. Instead of answering his question, he asked him back.


    In the face of Chen Xin''s rhetorical question, the researcher answered directly: "if this device can be used in all of China''s fighter planes, won''t they be able to carry twice the bomb load? In this way, we can gain more advantages in air combat! "


    With that, the researcher''s eyes showed a look of excitement.


    However, Chen Xin threw cold water on him: "the weight of the whole filling system is not to mention. When it is full, it will occupy most of the space of a fighter. The reason for mocking wind is that it doesn''t need the fuel tank to have an extra magazine in the fuselage to accommodate it.


    When it comes to other fighters, their structure is already very compact. To fight, they need external fuel tanks, and there is no room for this system in the belly.


    Even if it is forced to be loaded, it will only increase the take-off weight and slow down the flight speed, which will not play any role in actual combat. "


    Chen Xin''s words obviously darkened the researcher''s face. He also knew that things were exactly what Chen Xin said.


    If we can bring more ammunition, it is impossible for the former aircraft designers to miss these things. Even if they can''t make automatic loading, they will make more mounting points on the fuselage.


    But the researcher is still a little reluctant. After all, if the missile load of the aircraft can be increased, the firepower can be effectively improved.


    It''s just that not every fighter can save fuel tank and install only one reactor just like mocking wind.


    Even if other fighters are also transformed into nuclear powered electric propulsion, the fuselage structure, layout and many other factors are still restricting them, and it is impossible to insert the automatic loading equipment into the fuselage.


    It''s not that the researchers don''t understand this, but they will have some imagination when facing the automatic loading device in front of them.


    Unfortunately, this dream is doomed to fail, and Chen Xin seems to think that this is not enough, specially said: "and I am not satisfied with this automatic loading system. At that time, I just thought that there was still room in the cabin, and I just made such a system at any match point.


    In the actual test, the pilot also thinks that this system is not easy to use, so I intend to redo this system, or redo the whole missile launch part. "


    "Redo? What are you going to do, academician? " Another researcher heard Chen Xin say so, immediately asked curiously.


    In response, Chen Xin touched his chin and said, "have you ever seen a rocket launch nest? How about a similar missile launch module? "


    "Well This... " If you look at me and I look at you, I don''t know what to say for a moment.


    Although the rocket launching nest and the missile launching module are very similar in some sense, and the structure and principle are similar, they are still two different things in the final analysis.


    Moreover, the rocket launched by the launching nest is generally smaller, so it can be stuffed into a launching nest.


    But even if the missile is small, its volume is still there. It''s not impossible to plug it into a similar launch module, but its volume will be very large.


    Looking at the faces of several researchers, Chen Xin can certainly understand what they mean.


    As a rule, warships are the only ones that can fit missile launching pods, because subgrade missiles are usually one missile and one launching vehicle. Anyway, there is enough space on land to spread out, so it is not necessary to fit several missiles together.


    Only warships or aircraft have such demand.


    However, if the warship is big enough, it will be able to carry enough missiles. If the aircraft is not big enough, even if the missiles are not big enough, it still can''t carry so many.


    Although chiufeng is a special case, even if Chen Xin improves the missile carrying structure inside the aircraft, it is only able to install several more missiles, and it is not easy to launch.


    Just when everyone was in a dilemma, a ground technician suddenly asked: "this structure is really unreasonable. Maybe we can make the pylon into a traditional bomb pylon, and then launch it one by one like a magazine?"


    The ground technician said, but found that everyone''s eyes turned to him.


    This made the ground technician a little embarrassed, thinking that what he said was wrong.


    However, Chen Xin didn''t investigate. He just went to the belly of the aircraft and looked up at the automatic loading mechanism above his head and the missile pylons opened on both sides. After thinking about it, he said, "this proposal is not bad. If the bomb cabin is changed into a magazine type pylon, and the pylons on both sides are changed into a launching port, it will be better than the present one Structurally, it should be able to carry more ammunition. ""But in this way, you can only carry one kind of ammunition? This will have an impact on operational flexibility! " A researcher on one side thought along Chen Xin''s way of thinking and felt that there were still problems to be solved.


    "This is a good solution. Just open two more launchers on the back. The bomb compartment is divided into two parts. The middle part supplies the back launchers and the two sides supply the two sides launchers. In this way, we can carry two kinds of ammunition." Chen Xin just thought a little and gave a solution.


    After hearing what Chen Xin said, several researchers discussed it with each other and thought that this idea was more feasible.


    So one of them asked Chen Xin, "academician, do you need to modify the bomb cabin of the mocking wind fighter according to this plan?"


    "You first come up with a design plan. I''ll see if the bomb cabin is in a hurry. When your plan comes out, I''ll see if it really needs to be changed." Chen Xin was not in a hurry to start at this time, but let the researchers do the plan first.


    Although the transformation is very simple for him, it''s only a matter of thinking to get a feasible transformation scheme, but after all, Chen Xin is not a professional, so it''s better to let these researchers come up with a scheme, and he should improve on the basis of the professional scheme.

 Chapter 443

    The follow-up transformation of mocking wind is just one of many research projects in this scientific research base.


    Chen Xin just inspected a circle here, arranged the task, then turned and left.


    Now he is in charge of the whole scientific research base. For a single project, he is more responsible for these researchers to complete than for himself.


    However, because the scientific research base has just been completed and is not fully staffed, there are not many people in the scientific research base for the time being. We can''t make it work until the state sends the researchers.


    So after a turn, Chen Xin is ready to go back to his refuge.


    After all, the space in the whole research base is really open, even there is no plant in the ecological dome, which looks very empty.


    Fortunately, the seeds of plants will come with the relevant researchers, and they will start to plant after they settle down. Chen Xin doesn''t have to worry about the seeds of plants.


    As for the special forces, after the upgrade, the whole defense system has changed. Chen Xin needs to explain to the commander in the past and ask him to arrange for people to take over and control the whole defense system.


    Although the commander was surprised that Chen Xin upgraded and transformed the whole defense system, he did not show any incomprehension.


    He only asked Chen Xin for detailed drawings of the whole defense system so that he could deploy his own defense.


    In response, Chen Xin naturally readily agreed, and provided the commander with his own defense system drawings copied from the system, together with instructions for related facilities.


    This is what Chen Xin thought when upgrading. The upgrading of the whole defense system is not just a fence or power grid, but a complete set of automatic defense network.


    In addition to the wall, power grid and other accidents, surveillance cameras, patrol drones, automatic defense machine guns, dynamic induction alarm system And so on, many defense facilities are all over the research base.


    Without Chen''s drawing, it would take even well-trained special forces at least a week to figure out the general situation here.


    But now that we have the drawings and the specifications of the relevant facilities, the commander is confident that he will have a complete grasp of this place in three days.


    However, looking at the drawings and instructions in hand and seeing that Chen Xin has also deployed automatic defense machine guns and patrol UAVs, the commander deeply feels that unless someone uses large forces to attack, it is meaningless to attack here by means of group operations and individual penetration.


    He even estimated the possibility that these special forces under his hand would attack here after they had the new equipment provided by Chen Xin, but the result was an answer that made him feel a little frustrated and at ease.


    That is, when their special forces cooperate with the defense network, the same armed special forces need more than twice the strength to attack.


    This undoubtedly proves the reliability and security of the defense network, which also makes their security work better.


    Seeing that the commander was satisfied with the defense network, Chen Xin went back to his refuge without saying anything more.


    Of course, there are laboratories and offices for him in the ecological dome, but now that there are few people in the entire ecological dome, Chen Xin will not stay here.


    After returning to his refuge, Chen Xin is not used to the upgraded environment, but at least it is much more comfortable than before, which makes Chen Xin very satisfied.


    The workshop on the third floor of the new refuge is much better in terms of equipment and environment than the original one.


    If the original workshop is a processing workshop in a private garage, then the newly upgraded workshop is a processing center in a higher laboratory.


    Clean and tidy environment and sophisticated and advanced equipment make it possible not only to realize any of Chen Xin''s ideas and process all kinds of precision parts, but also to provide him with a good and comfortable working environment, so that he won''t be covered with stains after being busy like the previous workshops.


    What makes Chen Xin particularly satisfied is that in the process of upgrading, his original laptop has now become a graphics workstation, and a mainframe has been used as the storage terminal, and all data has been transferred to the mainframe.


    For Chen Xin, he used to use graphic workstations and mainframes when he was still at work. Now when he comes into contact with these things, he has a sense of familiarity that he has not seen for a long time.


    With workstations and mainframes, Chen Xin will be able to design drawings more conveniently and draw more complex drawings.


    However, the new device is certainly pleasant and gratifying, but Chen Xin did not immediately do something to try out whether the new device is easy to use. Instead, he sat in front of the work station, opened the screen and looked up his previously stored data.


    The problems in Southwest China are still lingering in Chen Xin''s mind. It has been less than half a year since the eruption of Duoba volcano, and the impact on the world has gradually begun to appear.Except for the frequent occurrence of small earthquakes in Southwest China in recent months, volcanic ash has not caused much impact.


    After all, the world is now shrouded in dust and haze. It has been a year or two since we saw the sun. The presence of volcanic ash just makes this dark day a little longer.


    What really worried Chen Xin was that after the plane was able to fly again, several deadly scientists took the plane to the stratosphere and collected air and dust samples from the stratosphere for analysis.


    In these air and dust samples, they detected not only the dust from the previous meteorite impact and the material from the dopa volcano, but also the eruptions from other volcanoes.


    After comparison, the scientists determined that it was the volcanic eruption from changgu volcano in the Federation and ASU mountain in the island country.


    And these two volcanoes are Grade 7 volcanoes that geologists determined earlier that may produce grade 8 eruption. Judging from the current situation, they have obviously erupted like DOPA volcano.


    At the same time, there are three volcanoes with a magnitude above 7, which is a disaster of extinction level for the whole blue star.


    The eruptions from the three super volcanoes have spread to the whole atmosphere. If there is no dust formed by meteorite impact, but only the volcanic ash can also make the blue star fall into volcanic winter and block the sun in the sky.


    Now, although the weather is not said to be getting worse, no one can predict what the eruption of the three super volcanoes will bring to the blue star.


    That''s why Chen Xin looked up the data he had stored, hoping to find a way to cope with possible disasters.

 Chapter 444

    For human beings, there are not many ways to avoid disaster.


    In ancient times, human science and technology were underdeveloped. At that time, most human beings had no resistance to natural disasters. Floods, earthquakes and other disasters could easily destroy human homes.


    A large number of people will die because of the disaster. Even the surviving human beings can only rebuild their homes, and more of them are displaced.


    So there were always refugees in ancient times. They were people who had to move to other places because they lost their homes due to famine or other disasters.


    Even in modern times, human science and technology have changed rapidly, but it is still quite difficult to fight against natural disasters.


    Ordinary small-scale natural disasters can still be resisted by human beings relying on the support of solid buildings and modern technology, at least not to be destroyed, and it is relatively easy to rebuild.


    However, in the face of major natural disasters that can change the terrain and change the way of mountains and rivers, human beings still have no resistance, or just can save their lives in the face of disasters.


    As for regional disasters, most of mankind still carry on the past. Fortunately, modern society is relatively advanced in science and technology, and post disaster reconstruction and resettlement of refugees are not too difficult.


    However, a global disaster like this meteorite impact is not easy to resist, and it is not easy to carry out post disaster reconstruction in order to get rid of the impact of the disaster.


    In such a disaster, the whole human civilization has no good way to resist.


    Originally, Chen Xin thought that the cold winter brought about by meteorite impact was the biggest challenge for human beings, but now the impact of the successive eruptions of three super volcanoes made Chen Xin realize that meteorite impact and long night cold winter are just the beginning.


    If we want to survive in this terrible disaster and continue human civilization, we need to face more challenges than we can imagine.


    It''s true that we can withstand the disaster by building underground shelters like this for a while, which is also the limit that human civilization can achieve under the current scientific and technological conditions.


    If you want more and better ways to fight against disaster, it can only exist in science fiction.


    What Chen Xin wants is the way to resist natural disasters in these sci-fi works.


    Said to resist natural disasters, "ark of tomorrow" this game is undoubtedly the most inspiring.


    In the ark world, in order to avoid natural disasters, human beings invented the mobile city. This kind of modular city can be divided and combined by units at will, and move by itself at the same time, so that the whole city has the ability of action and can avoid natural disasters. It is a very valuable existence.


    But it''s impossible to really build a mobile city.


    Not to mention the hilly and river network in the southern part of Yanguo where Chen Xin is now living, there is no condition for mobile cities to move. Even in the northern or plain areas where mobile cities can gallop, the existing technology of human beings can not build a vehicle that can carry a whole city.


    And even if Chen Xin really builds a mobile city by upgrading the system and provides relevant technologies for human beings, it will take too much resources to build a city that can move freely.


    More importantly, Bluestar is not Tara. There are not so many natural disasters to avoid. The city itself does not need to move frequently.


    So for Chen Xin, mobile city is just a good reference. He will make it when he really needs it. But before that, mobile city is far less practical and attractive than Rhode Island, the real protagonist in ark of tomorrow.


    Rhode Island is a huge land cruiser, its scale is about the same as an aircraft carrier, but it can drive on land, some similar to a small mobile city, but its area and scale is only as large as a small town.


    In fact, aircraft carriers built with modern science and technology are not inferior to Rhode Island in all aspects except that they can not travel on land like Rhode Island.


    Moreover, in terms of the size of the aircraft carrier, its interior is indeed equivalent to a small city.


    At least in terms of today''s shelters, the interior of an aircraft carrier can carry the population of the next medium-sized shelter.


    It is not a simple matter to move the aircraft carrier sailing at sea to land, or it is a problem that can be solved by the current technology of human beings.


    Even before the disaster, the whole blue star might have been studied and solved only by the Soviet Union and the Federation in the Cold War era, as well as by the rising states in the 21st century.


    And it will only be possible for these three countries to put in their efforts.


    It is no less than the super project of manned space project, only the really great country can realize it.


    After the disaster, Yanguo still has enough strength, but it''s too much investment to build such a giant on land.


    Now Chen Xin can only use it as a backup plan and can start to study it. He can''t say that he can definitely make it.Although he only needs to constantly invest in survival upgrade, he can upgrade a land cruiser like Rhode Island.


    "Land cruisers are still not useful in Southwest China." Although the manufacturing of Rhode Island has been included in the list of plans, in Chen Xin''s opinion, it is not very practical for a giant hundreds of meters long like Rhode Island to enter the southwest.


    Is there anything more practical? While recording the information of Rhode Island, Chen Xin continued to search for it.


    At this time, something suddenly occurred to him.


    In a novel he once read in the past, there are also descriptions of disasters. One of the stories is that the protagonist travels to the world of 2012, where there is no ark built by governments, but a private ark built by himself to avoid disasters.


    The way that the protagonist used was based on airship technology to build an air bag ark that could float in the sky, leading a group of people to escape the great flood in 2012.


    Maybe this is a good idea? If we can fly, the mountainous terrain in Southwest China will not be able to form a constraint.


    In this way, even if there is a large-scale geological disaster in Southwest China, which leads to traffic interruption, and it is impossible to enter the disaster area by land, and the plane can not land, there is still a way to enter the disaster area and move the victims out.

 Chapter 445

    Chen Xin had the idea of building airships for a long time, but the previous airship investment was too high in the first place and the cost performance was too low in the second place, which was not suitable for meeting the needs of the current country.


    But the balloon ark is different. It is more like a shelter that can fly. Some are similar to the lighthouses in the spirit cage, but it is much simpler and easier to build than lighthouses.


    Looking at the information he had collected before, Chen Xin was also thinking about how to build the air bag airship.


    At the beginning, the story he saw in the novel was too long to remember clearly, and he had no idea how to make it.


    At present, we can think of the same way as building airships, using large airbags as the source of lift.


    Because if we use the hot air balloon, the fuel is a big problem. Although heating the air can make the volume of the air bigger and provide more lift, it is obvious that the balloon ark needs a long time to fly, rather than falling down to replenish fuel after a period of flight.


    Chen Xin vaguely remembers that in that novel, the protagonist built a super large airship with an amazing load of 800 tons. If an adult weighs 60 kg, this airship is enough to carry 5000 people to live on, and has enough spare power to carry life supplies and other necessities.


    But how easy is it to build an airship capable of carrying 800 tons?


    The largest airship ever built in human history, the Hindenburg, has a load of only a few tens of tons. It''s impossible to build ten airships of the size of Hindenburg and then tie their air bags together, isn''t it?


    Not to mention how much resources will be consumed to build it, the final product will be a huge giant, which is not very cost-effective in terms of cost and investment.


    However, this idea inspired Chen Xin. Modern technology is not comparable to the Zeppelin era. Light alloy can greatly reduce the total weight of the airship and provide enough support to ensure that the airship''s air bag will not deform.


    The original Zeppelin airship was made of aluminum. Although aluminum is light, it is much heavier than carbon fiber and graphene.


    Scientists have already made new graphene materials in the laboratory that are lighter than plastic sheets but ten times stronger than steel.


    If the cost is not taken into consideration, Chen Xin is sure to increase the loading capacity of the new airship to 100 tons. In this way, it is theoretically possible to build an air bag ark that can carry 1000 people.


    With the support of the system upgrade, Chen Xin thinks that he can try to build such an airship for personnel transportation in Southwest China when necessary.


    After all, the most efficient domestic transportation is still the train, but in case of geological disasters, the train traffic will be greatly affected. Once the railway line is broken, there will be no way to go anywhere.


    The same is true for airplanes. The aviation network, which has just recovered its navigable capacity, relies heavily on airports. If there is no suitable airport for landing, even if there are airplanes, they will not be able to land, not to mention that ordinary airplanes can only carry more than 100 people.


    As for helicopters, it''s not far from being used to search and rescue and transport the wounded at the critical moment. But if you want to transport the survivors on a large scale, unless you can dispatch hundreds of them at a time, it''s just a drop in the bucket.


    Therefore, it is necessary to build a vehicle with enough carrying capacity and terrain adaptability.


    Now that he had made up his mind, Chen Xin opened the drawing software of the workstation and began to draw the design drawings.


    Of course, the so-called design drawing is just a concept drawing that can''t even be considered as a draft. The specific design will be improved only after it is completed. Now Chen Xin just records the ideas in his mind.


    It''s just a concept map. It''s very fast, of course.


    Chen Xin quickly drew a cigar like structure similar to the Zeppelin airship on the screen, with a large pod underneath.


    However, looking at this design, Chen Xin quickly denied such a design.


    The design of cigar type is not unreasonable, which can be regarded as a very classic design for airships. Even modern airships mostly follow this design, but special-shaped airships are rare.


    But what Chen Xin needs is an air bag ark with enough lift, not just an airship. Of course, enough lift and stagnation capacity are what Chen Xin needs. The faster forward speed brought to the cigar airship is optional for Chen Xin.


    So soon, the airship shape on the drawing became a disc shape.


    The whole airship looks more like an airship. The flat circular shape makes the airship look bigger. Although the length has not changed, the volume has undoubtedly increased a lot, the total amount of gas that can be contained inside has also increased greatly, and the weight that the airship can carry has also been improved.


    Looking at the modified structure, Chen Xin painted on it again. After a while, the design of the airbag ark was completed.


    It has a maximum diameter of 240 meters, and the height of the whole airship is 130 meters when it is full of gas. Chen Xin plans to use graphene material as a support and use multiple airbags to provide lift. In this way, when one airbags is damaged, other airbags can also provide enough lift, so that the whole Ark will not fall because of the damage of the airbags.The main part of the air bag ark is located below the air bag. It is a multi-layer dish structure with big top and small bottom. It looks like the inverted tower of Hanoi.


    The largest floor is used as a living cabin. The structure is similar to the circular layout of the city in the ice age. The rooms are arranged around the center to maintain the same size and area. The design can accommodate two people, with a maximum capacity of 1200 people.


    Further down is the living area and the power area at the bottom to ensure the normal operation and progress of the ark. At the same time, it also has the ability to temporarily prepare the gas required for the air bag inflation. When necessary, it can supply emergency gas for the air bag above the ark.


    As for the material storage part, it is placed above the living area and erected between the airbags, which can reduce the occupation of living space.


    But after finishing the whole design, Chen Xin can''t help scratching his head. It''s easy to make this thing, but the investment in this thing is still too high before large-scale and low-cost manufacturing of light materials.


    Apart from other things, graphene, which is used as airbag support, is a kind of material with excellent performance but extremely expensive.


    So before we build airbags, we need to get cheap materials? Chen Mo scratched his head, took his notebook and wrote about the large-scale preparation of light materials.

    Research on light materials, improvement of jeer fighter, research on ecological agriculture, manufacture of airbag ark, biological transformation of wolves


    Chen Xin turns over his notebook and finds that he has really added a lot of things to do during this period of time.


    Most of these projects belong to what Chen Xin wants to do, and they are not very urgent. So although Chen Xin looks at a lot of things to do, it doesn''t mean that he is very busy or has too many things on hand to do.


    Because doing research, unless there is such a systematic cheating as Chen Xin, every research is a long-term process.


    Even the most step-by-step and time-consuming improvement of the mocking wind fighter will take at least one or two years of testing to find out what needs to be improved before it can be modified and adjusted.


    After the adjustment, it may take two or three years to complete the transformation.


    As for the research of other projects, most of them are in the same situation. For example, the research of light materials, the emergence of graphene is not more than ten years ago. However, although a lot of achievements have been made in the research and application of graphene materials, the large-scale application is not so extensive.


    A new material research and development, researchers may be inspired to do things tomorrow, may also go into a dead end, more than a decade without results.


    Some people say that scientific research is like buying lottery tickets. The more you cast, the more likely you are to win.


    Some people even joke that if the European emperor is allowed to engage in scientific research, the possibility of producing results may be higher than that of professional researchers.


    Although it''s just a joke, it''s true that a lot of scientific research achievements come from the researchers'' flash of inspiration like winning a prize.


    Of course, it''s impossible to win a prize in this way for real research. We still need to screen out the wrong direction through a large number of experimental samples, and finally leave the exhaustive method in the right direction to get the right answer.


    As long as I have enough samples, I will be able to find the right answer.


    This is what many ordinary and great researchers do. For decades, they study a topic every day and repeat experiments hundreds or thousands of times in order to find out the possible differences.


    Chen Xin asked himself that he could not make such investment, but fortunately he did not need such investment.


    With systematic help, he is confident that he can solve these things in a short time, and achieve satisfactory results in every aspect.


    So although these things are all piled up in front of us, Chen Xin can still take his time and deal with them one by one.


    In fact, even if he wants to do these things together, he can. After all, the state has equipped a research team for each of these research projects in Chen Xin''s hands. With the completion of the construction of Chen Xin''s research base, these researchers have begun to report and work one after another.


    The researchers on the side of the mocking wind fighter are the first to arrive. They can be said to have come back with the plane and Chen Xin, so they have put themselves into work.


    If Chen Xin doesn''t plan to upgrade and improve the mocking wind fighter directly with the system upgrade, he can give the project to these researchers and let them carry out the improvement step by step according to the traditional procedures.


    In fact, it''s not just the improvement project of jeer fighter, light materials, ecological agriculture, genetic modification of wolves


    These research projects can be assigned to the national researchers. Chen Xin only needs to give the requirements and research direction, and give guidance and help when necessary. He does not need to spend too much energy to harvest results in a short time.


    But for Chen Xin, the efficiency is a little low.


    If Chen Xin just wants to be lazy, it''s no problem to do so. After all, even if he does, his research efficiency is still faster than others, and he can guarantee 100% of all the investment.


    But for Chen Xin, if he really wanted to be lazy, or just to make himself comfortable, he would not even want to build this research base.


    After all, his goal is to let more people survive in this human disaster and live a better life. For this purpose, Chen Xin will not choose any lazy and inefficient method.


    On the platform of the urban railway station, a train is stopping here, a group of people are standing on the platform, and the train is unloading.


    "Be careful. These are important experimental instruments. Everything should be handled with care!" A man with a horn is constantly telling the attention.


    "Xiao Wang, how many things have not been unloaded?" A grey haired old man came to the man and asked him.


    Seeing the old man coming, the man quickly replied to him, "Mr. Li, why are you here? These things will be unloaded soon. I''ll let them take you to the research base first. It''s too cold! You''ve been in bad health. Don''t freeze! "


    "It''s OK. It''s an old bone. It''s not so delicate." Li Lao didn''t care and laughed. He patted the protective clothing he was afraid of wearing and said with a smile, "besides, with protective clothing, I don''t think it''s too cold in this weather!"Seeing Li Lao''s action, Xiao Wang can''t help but look at his own protective clothing. This is the protective equipment that was distributed from the state only last year. It has its own heating function. In this extremely cold weather, it can really play a good role in preventing cold and keeping warm. Once it was launched, it was welcomed by everyone.


    And because of limited production capacity, this kind of protective clothing and supporting exoskeleton has always been in short supply.


    "Professor Li, there are still reports and handover in the research base. These things need to be connected with academician Chen. You''d better go with me first!" A woman in the same protective clothing persuades Professor Li that she is obviously better at speaking than Xiao Wang. After hearing her words, Li nods and leaves the platform with her.


    Seeing that Mr. Li and the woman left together, Xiao Wang was relieved: "it''s still group leader Tang who can talk, otherwise I really don''t know how to persuade Mr. Li!"


    Li Laoke is one of the state''s authoritative scholars in the field of ecological agriculture. This time, the state hopes that he will preside over the research in the field of ecological agriculture.


    It''s just that he is an 80 year old man after all. Although he has been taken good care of all the way, the old man is the old man, and no one dares to let anything happen to him.


    As for group leader Tang just now, he is the leader of the working group sent by the provincial government. He will be responsible for the administration after the scientific research personnel have settled in the scientific research base.

 Chapter 447

    On the way to the scientific research base, Tang Tang''s mood is a little complicated, and he is not sure about the work he will be responsible for.


    As a public official of the provincial Commission for Discipline Inspection, this kind of administrative work was totally unrelated to her.


    However, for some reason, the superior leaders chose her as the administrative director of the scientific research base, and gave her the job of receiving the scientific research personnel transferred from all over the country.


    This makes Tang Tang, who is always doing supervision work, almost afraid of others, lose his identity all at once, and the whole person is almost taken by surprise.


    Fortunately, in today''s big environment, everyone pays more attention to efficiency and practical work, but there is no past greeting and seeing off, which saves Tang Tang Tang a lot of time in dealing with interpersonal problems.


    What''s more, all of them are scientific research personnel. They pay more attention to reality. With the awe of the gold lettered signboard of the discipline supervision committee, Tang Tang has successfully completed his reception task.


    But now that she is going to the research base with these researchers, she has become a little worried.


    The reason for worry is very simple, because Chen Xin is in charge of the scientific research base, her younger brother many years ago, and they have met once before.


    Of course, Tang Tang understands that it is precisely because of this relationship that the superior leaders will transfer her to be responsible for the administration of the scientific research base. But it is also because of this relationship that Tang Tang worries about whether he can do this job well.


    Tang Tang is a very serious person. She doesn''t like to mix her personal feelings with her work, especially when she obviously uses her personal relationship to deal with work problems.


    Of course, her relationship with Chen Xin can make her work better and facilitate communication and cooperation with Chen Xinjin.


    But at the same time, it may interfere with her judgment and decision-making, or vice versa.


    It doesn''t matter if it''s good, but what if it''s bad?


    If things that would not have gone wrong had their own understanding with Chen Xin affected his judgment and led to problems, who should be responsible for such things?


    These problems for Tang Tang, can be said to make her deeply troubled.


    However, despite these problems, Tang Tang Tang is not a person who will be afraid because of difficulties.


    In that case, she would not have chosen the profession of disciplinary inspection committee.


    In the past, there were too many things in her work, such as selling people''s favor and trusting others. Tang Tang had already learned how to deal with the relationship between these things and work.


    If it wasn''t for Chen Xin''s special identity, Tang Tang would not have any worries at all.


    "I can''t, so I have to do business." As their car gradually approached the research base, Tang Tang settled down and set the tone for his future work. At the same time, he was thinking about how to carry out his future work.


    But before Tang Tang could figure out what to do next, the team was stopped by the special forces in charge of the security work of the research base.


    Tang Tang got out of the car and was surprised.


    The defense of this base is exaggerated!


    This is really a scientific research base, isn''t it a military base?


    Tang Tang looks at the special forces with live ammunition in front of him and the heavy mecha with black gun pipes in his hand. Suddenly, he has a great distrust of the job he is about to take over.


    Because the information she received before only said that this is a new research base set up by the state, there will be a group of scientific research personnel to be deployed, and someone needs to be responsible for the administrative work.


    That information also shows Chen Xin''s identity and related information in great detail, and someone listed the classmate relationship between Tang Tang and Chen Xin.


    But there was not a word in that document that there were special forces guarding here, with long guns and short guns.


    "Are you stationed here in charge of security?" Will bring the relevant documents to the soldiers in charge of the inspection, Tang Tang to one of the ranks is a second lieutenant asked.


    The second lieutenant took a look at Tang Tang. She had just introduced her identity, so the second lieutenant didn''t think it was impossible to say, so he explained to Tang Tang: "the main task of our army is to protect academician Chen, because he is in the scientific research base, so it is also included in our scope of protection together with the scientific research base."


    "You mean Xiao Chen No, academician Chen is now under the special protection of an army? " Tang Tang is very surprised. It''s the first time that she heard that in the state of Yan, someone needs an army to provide special protection in his place, which is not the treatment of the top leader!


    However, the second lieutenant nodded seriously: "yes, our task is to protect academician Chen."


    With that, the second lieutenant saw that the inspection had been completed, so he said to Tang Tang: "please come in. When you see academician Chen and get familiar with this place, you will know that academician Chen can afford this treatment."Hearing this, Tang Tang put away the returned identity documents and went back to the car. Then he entered the scientific research base with a somewhat shocked look.


    After Chen Xin upgraded the whole scientific research base, many places have become different and many details have been added, but the overall layout has not changed.


    So after Tang Tang''s motorcade passed through the barracks, they arrived at the entrance of the ecological dome.


    After getting out of the car and looking at the tall ecological dome in front of them, the researchers'' faces showed the same expression of fascination.


    "It''s such a big ecological dome. It''s much more powerful than Biosphere 2 of the federal people!" Mr. Li looked at the ecological dome in front of him as if he were looking at a treasure.


    It is undoubtedly very exciting and exciting for him to have such a large ecological experimental area for his research on ecosystem.


    If he was not too old, li felt that he could not wait to rush in.


    However, on the one hand, for the sake of heat preservation and on the other hand, for the sake of safety, the entry procedure of the entrance to the ecological dome is quite complicated, which requires everyone to clean and disinfect before they can enter.


    Mr. Li and other researchers can understand this level of measures very well. Usually, when they enter some laboratories with requirements for cleanliness, they also need to clean and disinfect. Some laboratories even need to change into protective clothing to remove dust before they can enter. Now, it''s just common for them to clean and disinfect.


    After a group of people entered the ecological dome, Chen Xin, who had been waiting for a long time, also welcomed them.

 Chapter 448

    After entering the research base, Tang Tang Tang quickly started his own work.


    All the researchers need to arrange accommodation, logistics supplies need to be distributed, and all kinds of complicated but very important work are piled up on her desk.


    Allocate the supporting dormitories of the research base, so that the subsequent researchers can settle in; count all kinds of materials, arrange the use plan; understand the specific situation of each laboratory, and formulate the management rules


    Tang Tang never thought that there were so many things to do to manage a scientific research base.


    Although she has done management work before, at that time, she was mainly in charge of an investigation team composed of several people. Compared with the huge scientific research base now, it''s really a small one.


    Fortunately, these things are relatively simple compared with the previous investigation of all kinds of cases that need to be taken apart. With the help of his subordinates, Tang Tang Tang quickly straightened out the clue, arranged all the work, and put the research base into operation.


    As for the work of scientific research, Tang Tang was not in charge of it. Chen Xin was in charge of it, while Li Lao assisted him in the management.


    Although Mr. Li is very old, he is in good health, and his age also means seniority and seniority. He can live well with his prestige. Even if he doesn''t need to do any specific management work, he can help Chen Xin coordinate the relationship and problems between various research groups.


    So after a few busy days, the whole research base is finally on the right track, all departments are running in an orderly way, and all research work is steadily advancing.


    Tang Tang sorted out all kinds of current situations and problems, listed them in a document, and planned to submit them to Chen Xin for review.


    This is her habit of working for many years. No matter how many jobs she has, she will sort out and list them so that she can check and solve them one by one.


    In fact, Chen Xin had the habit of running clubs together when he was studying. He was influenced by Tang Tang Tang.


    But at that time, Tang Tang was the president of the society, and Chen Xin was the one who helped her. Now the relationship between them is reversed. Chen Xin is the general director of the scientific research base, and Tang Tang Tang has become his "housekeeper".


    "At present, all the project teams are progressing smoothly. The improvement research team of the mocking wind fighter is improving the missile cabin pylon. Mr. Li is also leading people to design the construction of the ecological system in the ecological dome. The first batch of crops on the other side of the greenhouse have begun to sow. According to Mr. Li, this is their research project before the disaster, and now it just follows Continued research. " Tang Tang reports the current situation to Chen Xin. Although there are only a few words to sum up, it is the whole result of her work in these days.


    Of course, Chen Xin is very satisfied with Tang Tang''s work efficiency. However, after turning over a few pages of the report she submitted, he still asked Tang Tang: "sister, what''s the current situation of the physics laboratory and biology laboratory? I see what you said above is that the relevant equipment is not complete, and the research work has not started at present? "


    "Yes, they still lack graphene preparation equipment in the physics laboratory. At present, the research on related materials can not be carried out. Moreover, the researchers in the team also told me that even if they have equipment and enough raw materials, it will take a long time for them to make a breakthrough in new materials." Now that he has taken over the relevant work in an all-round way, Tang Tang naturally understands the situation. When Chen Xin asks, he tells him all the information.


    This is also understandable. After all, the research of light materials needs to be based on graphene. Without raw materials, scientists can''t develop new materials even by imagination.


    After all, practical research is different from theoretical research. It not only needs a lot of actual results to prove the theory, but also needs repeated experiments to prove the reproducibility of the results.


    What Chen Xin wants is a way to produce new materials on a large scale and at low cost. Without preparation equipment and raw materials, it is difficult to carry out specific research and experiments.


    Chen Xin nodded his head to show his understanding, so he said to Tang Tang, "sister, please tell them that advanced research, equipment and raw materials are also a matter of concern."


    "I know. Don''t worry." Tang Tang kept the matter in mind, nodded his head and agreed: "the relevant instruments and equipment in the biological laboratory are in place, but the person in charge there said that the live embryos and gene samples sent were too precious, and they had not done animal gene editing before the disaster, so they did not dare to waste them.


    And the person in charge also said that even if they can complete the gene compilation work you asked for, they can''t be cultivated without maternal embryos. Now there is no way to complete the whole process of artificial embryo development. "


    For this answer, Chen Xin expected, and he has already made preparations and plans.


    Embryo development needs necessary environment, which is a basic biological knowledge.


    The egg depends on the egg, and the fetus depends on the womb of the mother, which is the result of biological evolution and the necessary condition for life reproduction.


    Chen Xin plans to carry out the research on genetic transformation of wolves. The development of wolf embryos needs mothers. But now, in this environment, there are no two living dogs, let alone wolves?So the only way to do it is to find a dog as a mother to try cross species reproduction, or to use artificial breeding techniques.


    On the one hand, wolves and dogs are indeed close relatives, but in the final analysis, they are still two different species. It is still unknown whether there will be problems in cultivating wolf embryos in dogs.


    What''s more, even if you can use a dog as a mother, where can you find the dog when this kind of living animal is rare?


    So Chen Xin chose the second method, artificial technology to cultivate embryos.


    This technology had existed before the disaster, known as artificial uterus technology, but the related technology is not mature, can not really complete the process of an embryo developing from a fertilized egg to a mature individual.


    But this is not a problem at all for Chen xinlai. For things like artificial uterus, he can make available mature technology.


    "Don''t worry about this. I will solve the problem of embryo cultivation later. Since they are afraid of wasting valuable experimental samples, let them improve the relevant theory of this research first." Chen Xin thought about it. The live embryos and gene samples he sent were really valuable. They were unnecessary and should not be wasted. So he had better do theoretical research first, and then carry out practical operation after he helped them to complete the equipment.

 Chapter 449

    Since the disaster of meteorite impact, all countries in the world have been in the dilemma brought by the severe winter and long night.


    Yanguo is the best country in the world. After all, the government has enough control and mobilization power over the country, and it has made great efforts to make preparations. Therefore, both population and industrial production capacity have been preserved to a certain extent.


    But other countries are not so lucky.


    The Federation is the most miserable of the five Blue Star hooligans. The meteorite debris directly hit the mainland, causing the eruption of long island volcano. Before the extremely cold night came, the whole territory of the Federation had been reduced to scorched earth.


    Even if the federal government has a plan to deal with the disaster, only the army, scientists and the elite of the upper class can survive. The people at the bottom can only rely on their own hard struggle to survive, and the hope of survival is slim.


    Even if the Federation still retains a certain amount of national strength, it can no longer compare with that before the disaster.


    The loss of military bases all over the world and the sea and air power of blue star indicates that the Federation has lost its position as the first power of blue star.


    Even if the Federation can continue to exist in the future, it will not be able to maintain its position as one of the five Blue Star powers.


    The situation in England seems more miserable than that in the United States.


    As an island country, although in the past few hundred years, England once ruled a large part of the territory of the planet, known as the sun never sets Empire, but in the case of today''s sunset, what remains of this so-called empire is only the British three islands.


    Although England, located in Europe, did not face the tsunami caused by the impact of meteorite, the subsequent rise in global sea level caused a considerable part of the island country to be submerged in the sea.


    However, compared with the federal practice of completely ignoring the life and death of the people at the bottom and only retaining the elite class, ingrido is not so cruel to his own people.


    Together with France, the British government, at the cost of completely abandoning its native land and merging into France, obtained the permission of France to allow all English immigrants, so that the English people could cross the channel and enter the land of France and survive.


    As for France, although the two former empires still have a bit of family wealth due to the merger with England, now that the whole continent of Europe is in decline, there is really not much power to fight against the disaster. We can only say how much family wealth we can keep.


    Lucia''s legacy was not the most miserable.


    During the cold war, a large number of underground fortifications were built in suvia, which was originally used to resist a possible nuclear war. However, before the nuclear war came, suvia could not hold on and disintegrated, leaving only huge bodies to be carved up and slaughtered.


    Lucia, who has inherited most of suvia''s legacy, is one of the top five blue stars in recent years. Although the superpower''s foundation was almost defeated, some things that could not be defeated could still be used.


    For example, the subway network with a depth of 100 meters in the capital, originally built to prevent nuclear war, is now used to accommodate the people of Lucia who have taken refuge.


    In addition, Lucia itself is sparsely populated, and the pressure is not as great as that of other countries.


    It''s just that the weather is really cold. It used to be a country in high latitudes. When it''s freezing in winter, it''s normal to be tens of degrees below zero. Now the temperature is approaching more than 100 degrees below zero. Even if maozi''s body is full of cold resistance, it''s hard to resist such a cold winter.


    Originally, Lucia had to fight hard on her own. After all, everyone is living a hard life now, and no one has the spare power to help others in this situation.


    But recently, Lucia''s high-level officials received communications from Indonesia (in fact, the high-level officials of all countries have always maintained contact at the national level, and radio can guarantee this level of communication, of course, it''s just contact). Indonesia adheres to the traditional friendship between the two countries and is willing to provide some humanitarian assistance to Lucia.


    This information greatly shocked the senior management of Lucia. They knew that the situation of Yanguo was better than themselves, but they never thought that Yanguo could have the spare power to provide assistance at this time.


    In particular, although Lucia is theoretically bordered by Indonesia, the political, cultural and economic focus of Lucia lies in its European part, and the Siberian region of Asia is almost a no man''s land. At this time, Indonesia provides aid. How can they cross the continent of Europe and Asia between the two countries and deliver aid to the capital of Lucia?


    But it''s still a good thing to have help. Even if we have to pay more benefits and costs in exchange, it''s all a later thing for Lucia. The most important thing now is to tide over the current difficulties. It''s better to have someone to help than to resist.


    Originally, Lucia''s senior officials believed that Yancheng was transported from Siberia by land transportation. This railway was an important trunk line built in the era of suvia and connected with Yancheng''s railway network. Although the transportation was interrupted due to the obstruction of snow, there was still a way to go from land transportation.As for air power, Lucia has no expectations at all. Although it''s not impossible to take off with the scrapped aircraft engine in this situation, there is too little power that can be delivered and safety can''t be guaranteed.


    Unless it is a matter of life and death, countries will not waste precious resources that are already scarce.


    Therefore, Lucia would think that the way to send aid from Yanguo would be by land. They were ready to see the vehicles on the way from Yanguo.


    However, the way that Yanguo sent aid was far beyond the expectation of lucians.


    "What is that?" Several Lucian soldiers looked up at the sky. They were sent out by Lucia government to welcome the assistance of Yanguo after receiving the communication from Yanguo. But at the moment, they all looked up at the slowly descending giant in the sky: "is this an alien flying saucer?"


    Instead, a Lucia official on one side checked the notice he had received, took out his telescope and looked at the emblem and serial number on the giant, then said to the soldiers around with a trace of uncertainty: "that should be what we are waiting for, from the aid of Yan state."


    "This No one told me that Yanguo has been able to make UFOs! " When the officer in charge of the reception heard the official say so, he looked up at the huge flying saucer that was still descending overhead. His face was even more shocked than just now.

 Chapter 450

    When the suvians on the ground are shocked by the giant falling from the sky, the passengers on the giant are also surprised by the performance of the air bag ark they operate.


    "The temperature of the external environment is - 101 ¡æ. The No.2 engine is frozen and can''t deice automatically. The crew will send someone to deal with it." In front of the main console, the captain of the air bag ark took a look at the console in front of him, picked up the phone and gave orders.


    After putting down the phone, the captain could not help but sigh to the first mate: "it can still operate normally at more than 100 degrees below zero. The performance of this thing is really exaggerated!"


    "Yes, in this bad weather, it flies over 8000 kilometers across Eurasia. The performance of this kind of air bag ark is really amazing!" The first mate is also full of emotion.


    Although they have been used to the excellent performance of this air bag ark for a long time, they still can''t help feeling.


    This air bag ark is the latest air equipment of Yanguo. It was only started three months ago. A total of 12 vessels have been built. Eight of them are used for earthquake relief and resettlement of victims in Southwest China where a major earthquake occurred at the beginning of this year. Two vessels are responsible for material transportation, while the remaining two vessels are responsible for carrying materials to help Lucia.


    All the crew on the ark came from the Navy. Originally, they thought that the sea would be frozen and the naval ships would be lost. They would lose their role, but they did not expect that they would play a role again in this way.


    "Report to the captain, we have reached the predetermined altitude, we can see the capital of Lucia ahead, please give us directions!" A watchman reports to the captain through the intercom in the boat.


    Hearing the watchman''s report, the captain picked up the phone and said, "keep alert. The messenger will get in touch with Lucia according to the original plan and let them direct the direction!"


    When the captain gave the order, the first mate picked up the telescope and looked at Moscow under the ark. He said with some feeling: "Lucia''s capital, I was still studying here. I didn''t expect that now the whole city is buried in snow."


    "Which city is not covered by snow now? Do you think that the terrain of Chongqing is everywhere, and there are mountains everywhere The captain made a joke with the first mate.


    The two men have been together since they joined the army. Their old partner of several decades has already cultivated a tacit understanding. It is precisely because of this that the superior will transfer them to take over the air bag ark.


    Listening to the captain''s joke, the chief officer shook his head and said with great feeling: "I just think that these things taken out in China after the disaster are too amazing. If we don''t have these things, will we struggle for survival like them?"


    "If we didn''t have the treasures that were brought out after the disaster in these countries, we would have had a very hard time. You and I would not have had a chance to get together again, and we would have been able to come to Lucia''s place for humanitarian aid." The captain saw it very well, but he didn''t think the chief mate''s idea was meaningful: "but we can take out these precious black technologies, which is where we are better than them. And I think even if the country doesn''t have these black technologies, we will have a hard time, but it won''t be worse. The country can maintain the present situation, it doesn''t depend on black technologies."


    "That''s right. I think it''s bad. Without black technology, it''s just a bit hard. We can certainly overcome the disaster." The chief officer also felt that his ideas were redundant. Yanguo people were never technocrats or equipmentists. In their view, talent was the key factor in everything.


    While the captain and the first mate were chatting, the correspondent in front of the operation desk was also communicating with the ground in Russian by radio: "this is the Yanguo Xugou, coming to provide humanitarian assistance to your country, please provide orientation guidance!"


    Xu dog is the code name of this air bag ark. All the 12 air bag ark are named after the zodiac. This time, Xu dog and Hai pig came to Lucia to participate in the humanitarian rescue.


    After the correspondent yelled twice in a row, Vodka''s reply came from the radio: "Roger, we''re going to blow out red smoke!"


    At the same time of receiving the reply, red fireworks were also on the ground.


    Seeing the red fireworks on the ground, the captain was a little relieved. If there was no ground guidance, they would not have any problems, but it would be like looking for a needle in a haystack to find lucians in this city almost completely covered by snow.


    Even if the ark they also carry the country''s new breed of cold dogs, can be in the cold environment for certain search work is the same.


    It''s more than 100 degrees below zero. This kind of temperature is not suitable for any living things.


    "Turn on the searchlight! Contact the hogs and keep them in formation for landing The captain picked up the phone and gave new instructions.


    With the captain''s order, the huge searchlight equipped at the bottom of the ark came on. The snow-white light split the darkness like a sword. With the dog turning on the searchlight, the pig following him also turned on the searchlight.


    Two lights from the sky, the ground will be reflected in a white.


    Several lucians had to raise their hands to block the glare.For the first time since the disaster, they felt such a strong light, and their eyes were not adapted to it. But at this time, no one felt that the light was uncomfortable. Instead, they wanted to embrace it, because the light brought hope.


    Now for these lucians, all they expect is that these two giants will bring enough food.


    Although Lucia survived this terrible disaster by relying on the heritage of the suvia era, she did not live very well. Since the fall of the red giant bear, the people in this land have suffered a lot. This disaster only made the suffering more serious.


    Lucia official, who came to greet him, looked up and squinted at the shining giant. He couldn''t help feeling that if the red giant bear was still there, would the current situation be completely different? Does his motherland have the same ability to build such a huge flying vehicle?


    But all this can only be fantasy, the red giant bear has already fallen down 30 years ago, leaving only its body and traces of its existence.


    With these ideas in mind, Lucia''s officials saw a small airship like flying object break away from the large flying object and land towards the ground.


    While releasing the small airship, the large flying object is still gradually reducing its altitude.

 Chapter 451

    "Academician Chen, you really don''t have to go down to the ground. The disaster area is too dangerous now!" The captain of the ark is persuading Chen Xin.


    This time, the state mobilized eight newly commissioned airbags to participate in the earthquake relief work in Southwest China. As the chief designer of the airbags, Chen Xin took the initiative to follow the ark into the disaster area.


    On the one hand, it is for the further test of the airbag ark. Although it has passed the trial and acceptance, whether there is room for improvement is still to find out the problem through actual use.


    On the other hand, Chen Xin hopes to go to the disaster area in person to understand what the disaster area needs most, so as to provide targeted help for the disaster area.


    That''s why he appeared on the ark of the Chenlong, which was going to the disaster area for disaster relief, and the captain of the Chenlong was very worried about Chen Xin''s safety.


    For the National Academy of Sciences, the admiration for the captain of the ship is also of great significance.


    And he also understood the consequences of such an important researcher''s participation in earthquake relief and ark trials in case of danger.


    So he has been persuading Chen Xin to stay on the ark or just take the small airship equipped on the ark to observe the disaster situation in the air and not go down to the ground.


    However, Chen Xin shook his head in front of the porthole and said to the captain, "although geological disasters were expected to occur in Southwest China more than a year ago when Toba volcano erupted, and the balloon ark was also developed to deal with the disaster in Southwest China, now that the disaster has really happened, I still have to go to the front line of the disaster area in person to know the real situation in the disaster area What they need and how they can be helped. "


    "This..." Of course, the captain knows that what Chen Xin said is true, but he still thinks that researchers like Chen Xin should not take risks personally: "even so, academician Chen, you should stay in a safe place. I suggest you don''t go deep into the disaster area, just stay in the ark."


    In the captain''s opinion, the most important thing Chen Xin should do is to go back to the scientific research base immediately and stay well. However, since all the people have come to the disaster area, he can''t send them back, so he can only let Chen Xin stay in the ark, which is more or less safe.


    However, Chen Xin has directly rejected this.


    "That''s not good. I have a lot of tests to do. I can''t finish a lot of work in the ark." Chen Xin shook his head, refused and looked out of the porthole. He said to the captain, "it''s almost here. Prepare to land. I''ll see if the search and rescue dog is ready."


    With that, Chen Xin left the cockpit, but the captain looked at his leaving figure with helpless face.


    Although it is said that the captain has the highest command on the ark, it is still very difficult for Chen Xin, a researcher with high authority, to limit Chen Xin. The only thing he can do is to protect Chen Xin as much as possible to avoid danger.


    Leaving the cockpit, Chen Xin crossed the corridor and came to the small airship hanging on one side of the ark through the corridor bridge connected with the main body of the ark.


    This is the design added in the subsequent manufacturing process of the air bag ark. There are four grooves under the flat air bag to carry four small airships.


    On the one hand, these four small airships can provide additional lift for the ark while sailing, on the other hand, they are also used as transport boats and vehicles for the ark.


    After all, the ark is very big, so it needs a lot of space to land. Usually, the body of the Ark will not land on the ground, but transport materials and personnel by carrying small airships.


    It''s the same with the disaster relief this time. When eight airbags enter the disaster area together, they can be compared to eight football fields flying together in the sky, eight times more than Lao Wan''s famous scene. It''s almost impossible to find such a big place to land on the ground.


    When these ark were produced, they took off one by one, not eight together.


    Now, although the eight ark went to different places due to the division of tasks, it is still very difficult to find a place to accommodate the landing of a single ark.


    Therefore, a small airship less than 50 meters in length is very practical, and it is very easy for this small aircraft to land.


    "Academician, all the 12 search and rescue dogs we brought have been on the airship. Except for No. 4 and No. 7, they seem to be in a bit of a bad mood. Other dogs are in good condition and can be put into work at any time." A staff member saw Chen Xin coming and reported the situation to him.


    Listening to the staff''s report, Chen Xin turns his eyes to the cabin of the airship. Five white and gray wolfhounds are lying on the floor of the cargo hold, but two of them are not in good spirits. Their trainers are comforting these big guys.


    These five search and rescue dogs are the result of Chen Xin''s genetic transformation of wolves. The average shoulder height is one meter, the body length is more than two meters, and the weight is 65-80kg. The size of these dogs is comparable to that of some ponies, not as powerful as lions and tigers, which are large cats.


    And they also have a strong sense of mobility and group cooperation. They can walk at a speed of about 10 kilometers per hour for more than 10 kilometers, chase their prey at a speed of nearly 65 kilometers per hour, sprint at a distance of 5 meters per step, and their thick fur can survive at - 50 ¡æ.In addition, when carrying out genetic transformation, Chen Xin also specially improved their intelligence, being able to understand more complex commands and express themselves clearly with actions.


    In addition, the canine genes were integrated into the transformation process. These genetically modified wolfhounds were very loyal. In several rounds of tests, they showed a high degree of dependence and loyalty on human beings, and they would not attack human beings even when they were very hungry.


    On the contrary, their enhanced sense of smell can accurately smell the human smell in complex and bad conditions and take the initiative to rescue, which can be said to be a very qualified search and rescue dog breed.


    When Chen Xin entered the disaster area this time, he specially brought all 60 adult dogs bred in the scientific research base during this period. Except for 10 dogs, which were given to the two ark going to Lucia for rescue, the remaining dogs were all concentrated on the eight ark coming to the disaster area for rescue, and there were also five dogs on the Chenlong.


    Later, they will follow the first group of search and rescue personnel to land on the ground to search and rescue the disaster area and participate in the rescue work.


    And Chen Xin will go down with them to understand what the first-line disaster stricken areas need, and at the same time, he will further observe and record these big guys.

 Chapter 452

    Whether it is a small airship or an air bag ark, the materials used are all new lightweight materials developed by Chen Xin''s scientific research base.


    This new lightweight material is called "cloud steel" by Chen Xin. Although it sounds vulgar, it can well reflect the characteristics of the material, light and tough.


    After Chen Xin''s scientific research base was officially put into operation, he helped the physics laboratory to transform the graphene preparation equipment and improve the production process, greatly improving the production speed of graphene and reducing the cost, which made the light materials he needed to be successfully developed.


    After that, it is natural to set up a production line for mass production, which can complete the whole process from design to service in just four months.


    This kind of light material is not only used in the manufacture of airbags and small airships, but also has been put into use in the field of aviation manufacturing. After the mocking wind fighter was finalized, some parts of the aircraft were made of this material to reduce the weight of the aircraft itself.


    Other aircraft are also starting to use parts made by Yunnan steel. Although the scale of application is not large, it marks a beginning.


    In the past half a year, Chen Xin''s research base has also made fruitful achievements in the field of ecology, in addition to the tasks of wolf genetic transformation, research and development of light materials, manufacture of airbag ark and improvement of mocking wind fighter.


    And according to the achievements of Chen Xin''s research base, the country has set up a large number of greenhouse planting bases in the two lakes area, and the first batch of grain and vegetables have been produced.


    These grains and vegetables are mainly rice, soybeans, sweet potatoes, cucumbers, tomatoes and other common crops. After being processed by manual methods, they will be made into synthetic food blocks, some of which are similar to compressed biscuits, but they are more nutritious and hungry.


    After eating a small piece of food for a whole day, it will not be enough for adults to feel full for a long time.


    With the seasoning of Chen Xin, an intermediate chef, the taste and taste of this food are actually quite good. It''s a good kind of food, not only for people, but also for animals.


    It is precisely because of this technology that Chen Xin and his family can afford to raise the genetically modified large wolf dogs. Otherwise, the food intake of these large animals is very exaggerated. Even if they can be vegetarian, they can''t afford to raise them casually.


    This time, the ark went deep into the disaster area and carried a large amount of this kind of synthetic ration, which was used to distribute food to the victims at the first time.


    In addition, the ark is carrying emergency relief tents and heating equipment as well as medical supplies and other badly needed things in the disaster area.


    According to Chen Xin''s original plan, the airbags ark was designed to be an air shelter with complete facilities. After the victims are rescued in the disaster area, they can be directly placed, and then they can fly to the rear to unload the people.


    But after considering the actual situation and the carrying capacity of the ark, Chen Xin gave up the idea of air shelter and instead designed the air bag Ark as a transport ship.


    It''s not that air shelters don''t work, it''s unnecessary.


    Take the disaster relief in Southwest China as an example. The speed of the air bag ark is 240kmh, which is not slow, but it is troublesome for the ark to take off and land, and the transfer efficiency of small airships is relatively low.


    Although the ark can carry 1200 people at a time, with a maximum of 1500 people, it can transport people from the disaster area to a safe area for resettlement, which is almost a day away.


    Even if they were resettled nearby, with the speed of the ark, the eight ark participating in the disaster relief could save tens of thousands of people in one day.


    If only one city is affected by the disaster, of course, we can do so, but this time, the whole southwest region has been affected!


    Although the disaster situation in most areas is not too serious and there is no need for resettlement and transfer, there are still at least 100000 people in the core area of the disaster area who need to be rescued.


    Therefore, if we use the ark to transport the affected population, we should pay attention to efficiency and speed. Most people may stay on the boat for a few hours. There is really no need to design the Ark as a shelter for long-term residence. It is better to make room for more people.


    Therefore, the current airbags ark really deviated from Chen Xin''s original idea and became a large transport ship rather than an air refuge.


    But in this way, it also saves more transportation capacity, which can carry more materials or carry more victims.


    As for small airships, they are only traffic boats between the ground and the ark.


    It can be moored on the ark, powered by two electric propeller engines and powered by isotope thermoelectric batteries. It can carry 30 people or about 2 tons of materials.


    Now the four airships on the Chenlong are loading materials and rescue workers, but Chen Xin also has five search and rescue dogs on board.


    It took some time to land on the ground, and the two staff members on the airship first reached the ground through the hanging rope, and fixed the anchor and cable dropped by the airship, so as to pull the airship to the ground bit by bit.After all, this thing relies on the air bag to provide lift. It doesn''t fall to the ground completely by itself, but it still needs a little help when landing.


    When the bottom of the airship touched the ground, Chen Xin and others walked down from the airship.


    Several rescue workers were carrying the materials on the airship quickly, while several search and rescue dogs were led down to start the search and rescue work.


    The airship itself has to return to the ark and continue to transport materials.


    Chen Xin didn''t care about the airship behind him. After unloading the materials, he took off again. The crack in front of him, which is more than ten meters wide, has deeply shocked him.


    Just now when he was in the sky, he had noticed the cracks on the ground, but he couldn''t really see them before. Now when he landed, he could clearly see that the snow more than ten meters deep had all cracked due to the damage caused by the earthquake, forming huge cracks, exposing the original ground below.


    Some of the buildings that were buried in the city have shaken off the snow and re exposed the ground due to the earthquake, but they also collapsed due to the earthquake.


    The whole city still can hear the sound of houses falling or snow falling from time to time. Even the crack in front of Chen Xin and his family is still in the process of breaking ice and snow falling from the section to the bottom of the crack, making a huge sound.


    "Academician, please stay in a safe place. The ground is not stable. You must pay attention to safety." A staff member next to Chen Xin pulled him back to avoid him getting close to the crack.


    Chen Xin recovered and said to the worker, "I know. I''ll pay attention to it. Now let''s rescue first."

 Chapter 453

    Li Xi pulled the quilt on his body, trying to make it a little tighter.


    However, even if wrapped tightly, in the face of the low temperature of dozens of degrees below zero, it still does not play a role.


    But this is the only thing Li Xi can do now.


    In front of the fire, there were only a few embers that were not cool enough. Although there were still some flames, he had nothing to burn.


    And it''s not just fuel. In the morning, he had finished the last food he could find, and he drank


    Li Xi reached out to pick up the kettle beside the fire and shook it. He didn''t hear the sound of water. It was obvious that the remaining half pot of water was frozen.


    This is the third day of the earthquake. Although Li Xi was lucky, he escaped from the semi collapsed shelter for the first time, collected some food, clothes, bedding and other things that could be used for heating, found a place to shelter from the wind and built a fire, he was still about to die of freezing.


    Li Xi is desperate. Although he knows there are other survivors and the government should be organizing disaster relief, he still feels that he can''t stick to it.


    Because it was so cold that he felt that his blood was freezing, and even his heart was frozen.


    He was about to lose consciousness. His hands and feet were frozen yesterday. Now he even felt that his thinking was blurred.


    "I''m so hungry It''s so cold... " A few vague words floated out of his cracked lips, as if they were the last groans, telling of his last desire.


    At this time, Li Xi felt that he had an illusion in front of his eyes. He seemed to see a burning stove, emitting warm light, and in front of the stove was a table of mouth watering delicious food.


    The table is like the last New Year''s Eve dinner before the disaster. There are chickens! There are fish! There''s meat! Have their favorite spicy chicken and pig hoof!


    Beside the table was her mother, who had passed away because of her poor health after the disaster.


    But in Li Xi''s eyes, his mother is still the kind-hearted one she used to be, smiling and waving to her, as if she was greeting her to have dinner.


    It''s just like when I came home from school thousands of times from childhood, my mother had already prepared dinner for me and asked me to have dinner.


    "Ma!" Li Xi wants to reach out to his mother and catch her, but he can''t catch her.


    Just when Li Xi wanted to stand up, a beam of strong light hit his face, which made him cover his eyes.


    "Find the survivors!" Li Xi''s ear seems to be the sound of rescue, there are messy footsteps.


    But Li Xi doesn''t care any more. Now he just wants to sit down at the table and eat his favorite food with his mother, just like in the past.


    However, when Li Xi was thinking like this, he felt that his face met a hot thing. Not only did he get angry, but also a wet, soft thing swept around his face.


    Li Xi wants to open his hand, but his hands are already unconscious, which makes him particularly upset.


    Because of the interference of this thing, his mother and the dining table in front of him are getting farther and farther away. He must drive away this thing, so as to seize the opportunity to eat with his mother.


    But Li Xi raised his eyes to see the huge strength of his drummer.


    A big white wolf dog higher than Li Xi was sitting was sniffing on Li Xi''s face. Maybe it was too cold. The big wolf dog didn''t stick out its tongue to lick him. The wet thing Li Xi felt just now was just the dog''s nose.


    "How can there be a dog?" Li Xi seemed to be a little sober at this time. He looked his frozen head aside and saw two Gray figures crawling in along the passage opened by the dog and running towards him quickly.


    "Wake up! Don''t sleep! Wake up! Hold on Two people quickly came to Li Xi''s side, one quickly took out a thermos cup from his body and fed Li Xi a hot drink in his mouth, while the other hurriedly checked his state, and at the same time said aloud to him, asking him to hold on.


    But Li Xi was too tired and too cold. The warm hot drink flowed into his mouth. Although it made Li Xi wake up a little, he couldn''t hold on and lost his head.


    Seeing this, two rescue workers did not dare to neglect him. They fixed him to the search and rescue dog with a fixed belt and said to the big wolf dog, "come on, send people back!"


    The wolf dog understood the instructions. Although it was a bit difficult to tie a person on his body, the wolf dog quickly crawled out along the channel he opened, and quickly ran to the rescue point with his people.


    After the wolf dog went out, two rescue workers were still searching for other survivors in the collapsed ruins.


    They were lucky that they brought large search and rescue dogs, which were as strong as lions and tigers. After smelling the survivors under the ruins, they were able to dig away the snow and ruins at a very fast speed and find the buried survivors.With the ability of these big dogs, they have found many survivors.


    If it is in the past, it may be necessary to dig up the ruins above to send people out, but this huge wolf dog can fix people on them and then be taken out by dogs.


    "Fortunately, I brought these big dogs with me this time. Previous search and rescue dogs didn''t have this ability!" A rescuer continued to scan the ruins with instruments, feeling.


    "Yes, if the dog, let alone search and rescue, this kind of weather is freezing to death." Another rescuer also had some feelings. He obviously thought of his former partner.


    But unfortunately, after the disaster, he lost his old partner.


    "They are really good at digging holes. It used to take hours to dig in. Now with these big dogs, the search and rescue is much faster!" The first rescuer seems to have found another survivor and quickly patted his partner: "someone is still alive below! Come and help


    The two men saw that the instrument showed that there were still survivors under them, and they quickly dug the ground with their own tools.


    Although their digging speed is not as fast as that of wolf dog, with the help of exoskeleton, two digging tools are still digging the ground quickly to dig out the survivors.


    On the other hand, Li Xi, who was rescued by the wolf dog released by them, has already run to the street.


    The big dog almost kept on sniffing the air, then ran in one direction, and soon came to a temporary rescue point, barking loudly.


    And the staff who noticed the big dog also ran towards him, untied the man hanging on him and sent him for treatment.

 Chapter 454

    The situation in the disaster area is much more serious than Chen Xin initially expected.


    The earthquake caused many shelters to collapse and damage. Electricity, water supply and heating were all cut off. Buildings and snow fell everywhere in the city. The survivors either stayed in the ruins of the shelters or escaped from the shelters, but they were frozen in the cold wind because of the cold.


    Like Li Xi, who can hold on until the rescue arrives, there are no survivors.


    The situation here is much worse than when we were in Linshi.


    The city is only buried by snow, the city''s heating and power supply are not interrupted, and the collapse of the medical system is only because it carries too many patients.


    However, the power supply network of this city has been paralyzed. Although the power plant is only slightly damaged, the local government has been organizing emergency repair, but the power supply line is interrupted due to the earthquake, even if the power plant is repaired, it can not restore power supply.


    Although each shelter has isotope temperature difference battery which can supply power independently, the damage of the shelter itself causes most of the shelters to lose the ability of power supply and heating.


    Survivors can only hide in the ruins that have not yet completely collapsed, and try every means possible to maintain their body temperature, so as not to be frozen to death before the rescue arrives.


    But there is still little hope.


    A large number of survivors are buried under the collapsed ruins of the shelter. The abandoned buildings outside the shelter are also collapsing. The collapsed abandoned buildings will also bury the entrance of the shelter. If there is no external rescue, these shelters are likely to become a ready-made tomb.


    And time is running out. In the low temperature of dozens of degrees below zero, lack of food and heating, these people will not last long.


    However, the strength of the rescue team brought by the eight ark is limited. Without heavy machinery, it is difficult to dig up these collapsed buildings.


    How to more quickly and effectively rescue the survivors buried under the ruins has become the primary problem in front of the rescue team.


    The local municipal government has made contact with the rescue team, and part of the manpower that can be organized is also cooperating with the rescue team to carry out the search and rescue, but it still feels like a drop in the bucket.


    In the temporary rescue site, the local vice mayor is nervously discussing with Chen Xin and others how to carry out the rescue operation.


    "The municipal government has a batch of construction machinery, which can be put into the rescue operation." The vice mayor''s face was grim. He told Chen Xin and others about the rescue power that the city government could provide. At the same time, he was worried and said, "but the key is the shortage of manpower. Your rescue team has 800 people. At present, there are only more than 1000 people that the city government can organize, and 2000 people are not enough!"


    For this problem, the leader of the rescue team nodded, frowned and said: "there are too many collapsed shelters. Even if there are exoskeletons that can exert the power of several people, there is no way to dig up so many collapsed shelters in a short time! There must be more people or more powerful means to open these shelters! "


    "Before we set out, the country was already organizing the follow-up rescue forces. The air force will have transport planes carrying airborne soldiers to assist. I asked the captain of the Chenlong to contact the rear. They should arrive before six o''clock tomorrow morning." Chen Xin reported the information he knew to others, and looked at his watch: "it''s 2 a.m., and there are four hours left."


    "Let''s try our best to carry out the rescue first. It''s so cold and the earthquake has happened for so long that many people may not be able to hold on!" As a local official, the vice mayor knew that the earthquake had happened so long that even if someone could survive in the first place, it would not last long in such cold weather.


    Now it''s different from the past. In the past, the temperature was not so low. Even if the survivors didn''t eat or drink, they could persist for a long time. However, in the low temperature environment of dozens of degrees below zero, it''s very likely that they would be gone in a few hours.


    So now we have to fight against the clock.


    "First, put all the construction machinery into the rescue work, and clean up an airborne field as far as possible, so as to be ready to take over the airborne." The leader put forward the most feasible suggestion he could think of in the present situation.


    Chen Xin also had no objection to this, nodded and added: "the rescue team we brought is equipped with exoskeletons, so that they can be divided into several teams. First, we can go to the collapsed shelter to check the situation and get through the rescue channel.


    Even if you can''t get people out, you have to pass on the news that someone is coming to save them, and input the necessary food and water into the collapsed shelter to give the survivors hope!


    In addition, the tents we brought should be put up as soon as possible, and the survivors who have been rescued should be placed as well as possible! "


    "I''ll arrange the resettlement work. Deputy Mayor Zhao, you''ll organize the rescue work!" After hearing Chen Xin''s words, the leader of the rescue team made arrangements without any nonsense.


    "Well, I''ll take care of the rescue." The vice mayor was not polite either. He agreed happily. At the same time, he said to Chen Xin, "I''ll ask academician Chen for help from my superior."


    Of course, Chen Xin would not refuse, but also nodded and agreed: "no problem, I will contact the higher authorities and strive for more materials and manpower."After discussing the division of labor, we didn''t waste time, so we started to act separately.


    However, after walking out of the tent, Chen Xin looked at the busy rescue site outside and the ark hovering overhead. After thinking about it for a while, he suddenly said to the leader, "classify the survivors. If they are in good condition, let them have a rest and come to help save people. Even if they can''t help dig out people, they can help to place new survivors at the rescue site.


    As for the more serious survivors, small airships should send them to the ark. The conditions above are better, which is also conducive to the recovery of these survivors. Let them stay at the rescue site all the time, not only occupying the place, their mental state also affects the other survivors at the rescue site. "


    "OK, I''ll arrange it. Academician Chen, please contact your superiors as soon as possible." After listening to Chen Xin''s suggestion, the team leader also thought it was a good plan.


    The ark has now unloaded most of its materials, and its internal space is empty. It can indeed place some of the more serious survivors on it.


    If the ark needs to transfer materials, the survivors can also be sent to the rear for treatment, which will not affect the use of the ark.


    After Chen Xin finished his suggestion, he also boarded a small airship and went back to the ark of the dragon, intending to borrow the Ark''s communication equipment to inquire about the follow-up support.

 Chapter 455

    Chen Xin originally wanted to devote himself to the front-line disaster relief work. After all, his nano armor can be turned into large-scale construction machinery, and can also be turned into fog to penetrate into any crevice. Whether it is used for rapid excavation or to find survivors, it will have high efficiency.


    But both the vice mayor and the leader of the rescue team prevented Chen Xin from going to the front line to participate in the rescue.


    Scientists like Chen Xin should stay in the rear. Even if he has to come to the front line for any needs, he can''t set foot in dangerous places.


    After all, building collapses and avalanches still occur in urban areas from time to time, and even aftershocks have happened twice again. Under such circumstances, Chen Xin goes deep into the front line to participate in the rescue. In case of an accident, it will be the loss of the whole country.


    So even if they know that Chen Xin''s help can enhance the rescue force, they dare not let Chen Xin risk for this.


    Fortunately, Chen Xin himself knew that going to the front line to help would only add unnecessary burden to other people, so after two words of advice, he did not insist on directly participating in the rescue, but stayed at the rescue site to take charge of his own work.


    The air force said that the paratroopers would arrive on time. By that time, 400 paratroopers would directly parachute into the core area of the disaster area to provide support for the rescue team.


    However, it is still very difficult to transport the relevant relief materials into Kauai. Only the Wuma and Chou Niu, who are currently in charge of the transfer of materials, can carry out large-scale material transfer and some personnel transfer.


    In this regard, after discussing with the rear, Chen Xin transferred two ark boats from the rescue boats in the disaster area to participate in the material transfer, trying to transport more materials for the disaster area. At the same time, he also sent the survivors who are in poor condition and need treatment to the rear.


    At the same time, Chen Xin also contacted his own scientific research base and informed Tang Tang Tang to send new equipment in the experimental stage by transport plane, so as to provide more help for the disaster area.


    "New equipment? But that thing hasn''t passed the test. Is it safe? " Tang Tang received Chen Xin''s order. Although he knew that life in the disaster area was at stake and that rescuing the victims was more important than anything else, he was still worried about Chen Xin''s new equipment.


    Chen Xin, however, was adamant and said to Tang Tang Tang with his phone: "now that more support is needed in the disaster area, I regret that I agreed to let Xugou and Haizhu support the lucians. Although they are also miserable, we should really provide some help within our ability in this case, but now we are almost too busy to help ourselves!


    This batch of new equipment has passed the basic test and logic test before, and the safety test is better to directly carry out the actual combat test than to put it in the laboratory. Even if it is dangerous, it is worth rescuing more victims. "


    "Well, if you insist, I reserve my opinion." In the face of Chen Xin''s insistence, Tang Tang does not agree with the risky move of putting the equipment that has not passed the test directly into the rescue operation in the disaster area, but she does not firmly oppose it.


    Chen Xin is aware of Tang Tang Tang''s mood, but he can''t worry about so much at this time. The disaster area needs that batch of new equipment.


    "Arrange the shipment as fast as possible. I hope to see them arrive in the disaster area within 24 hours." Chen Xin says to Tang Tang Tang, confirms that she has received her own order, and then hangs up the communication.


    Unable to participate in the disaster relief work in person, Chen Xin did not go down to the ground at all. Instead, he came to the cab of the ark and looked down through the porthole to the rescue spot illuminated by the searchlight of the ark.


    People on the ground are as busy as ants, searching for signs of life, excavating ruins, rescuing survivors, transporting survivors to rescue sites for treatment


    All the people are busy, and the tents in the rescue site are constantly in and out, and each tent is constantly receiving the rescued survivors.


    And some survivors in serious condition are being transported to the ark by small airships.


    Compared with the tents temporarily set up on the ground, although most of the airship''s interior space is cargo space because it does not adopt the scheme of air shelter, the needs of taking in the wounded when carrying out the disaster relief mission are still considered in the design. The internal design of the sick room can accommodate the wounded, and only needs a little change and adjustment, it can become an air hospital.


    Therefore, after the more serious survivors were sent up, they were soon resettled.


    Just looking at the busy crowd, Chen Xin regretted that he had voted for it when he agreed to send two ark boats to Lucia to carry out the rescue mission.


    If we can get two more ark, we can save more survivors!


    Although the decision to provide assistance to Lucia occurred before the earthquake in Southwest China, Chen Xin regretted that he did not insist on keeping all the ark when he voted at that time.


    But this kind of thing is really hard to predict in advance. Now, Xugou and Haizhu two ark should have been flying to the capital of Lucia. Even if they turn around now, they will have to fly for another half a month.


    So Chen Xin quickly adjusted his mood. Instead of regretting that he let two ark ships go to Lucia, he thought about how to transfer more rescue forces to the disaster area.The airborne troops of the air force can make up for the shortage of manpower, but there is still a big gap in the construction machinery.


    When discussing the rescue plan with the vice mayor just now, he had already reported the number of construction machinery that the local government could mobilize. Although there was a batch, the number still could not meet the needs of rescue.


    But the personnel is easy to deploy, construction machinery is not so lucky to come in.


    Even the smallest excavator weighs a few hundred kilograms, while large excavators, cranes and other construction machinery weigh several tons, more than ten tons, or even dozens of tons. Even if these construction machinery are transported by ark, they can''t be transported much.


    What''s more important is that there is no airport for planes to take off and land in the disaster area, and the airborne soldiers can parachute. Are these construction machinery also parachuted down with the airborne soldiers?


    Therefore, the construction machinery that can be easily transported by aircraft and deployed to the disaster area in the form of airdrop with airborne soldiers has become the most needed materials in disaster relief.


    Fortunately, in the past half year, in addition to focusing on several major research projects, Chen Xin has also made time to manufacture a piece of equipment that he had planned for a long time, but had no time or opportunity to manufacture.


    Although there is no large-scale mass production of this equipment for various reasons, and only a small batch is trial produced by the scientific research base, they can just meet the requirements of air transportation and airdrop, and solve the urgent needs of the disaster area.

 Chapter 456

    In the sky, several large transport aircraft are flying slowly over the disaster area in formation, and their umbrellas are blooming behind them.


    More than 400 paratroopers are jumping down from the sky with great courage and heading for the preset landing field.


    As airborne soldiers, although they haven''t had airborne training for nearly two years since the disaster, parachute jumping, a basic skill of airborne soldiers, is still firmly engraved in their bones and is not forgotten or unfamiliar because of time.


    However, even the most experienced paratroopers may not have parachuted in such an environment.


    At the foot is the disaster area after the earthquake. The earth is tearing, buildings are collapsing, and mountains and rivers are broken. Although everything is shrouded in darkness, the light column cast by the huge ark in the sky still makes the city like ruins discernible in the night sky.


    This is also to guide them to parachute, so as to prevent them from falling into collapsed buildings or other severely damaged places due to the relationship of night, which deviates from the original designated landing site.


    The landing site specially designated for this group of airborne soldiers is illuminated by a giant searchlight, which is particularly conspicuous in today''s dark environment, so there is no possibility of mistake.


    But all of these give people a kind of fantastic unreal feeling, whether it''s the huge air bag ark, or the huge searchlight illuminating the landing field, or the huge figure descending with these airborne soldiers.


    That is the experimental equipment transferred by Chen Xin. Under the deployment of Tang Tang, they were finally loaded with the large transport aircraft sent by the air force in time, and arrived in the disaster area together with the second batch of airborne troops.


    These huge figures have roughly the outline of human shape. They look almost as high as two or three floors. Maybe it''s due to the trial production of models. Some of them are of different sizes.


    There are about twenty of these huge figures. Although they are of different sizes, they are all carrying three large parachutes for airborne tanks. Only a few of them do not open their parachutes, but rely on their own engines to control the speed of their fall. Obviously, these very few are capable of flying.


    With the decrease of height, the lights gradually illuminate these huge figures. They all have metal primary color shells and look like some giant robots.


    Their bodies look round or square, and some are slim, but without exception, their trunks are more or less bloated.


    The emergence of these big robots is obviously very eye-catching. Whether it is the airborne soldiers who are falling with them or the rescue teams waiting for reinforcements on the ground, they are obviously interested in these people who are very conspicuous at first sight.


    However, Chen Xin himself is the only one who knows enough about these big robots. He has already talked with the leader of the rescue team, the local vice mayor and other key figures, but he has not caused unnecessary misunderstanding.


    Among these large robots, those with flying ability fall a little faster. They first land on the ground. One of them, which looks thinner and taller than other individuals, walks around for a while and then walks towards Chen Xin and others who are waiting in a prominent light.


    Seeing the big robot coming towards him, the vice mayor and the rescue team leader, who were waiting for reinforcements with Chen Xin, were a little nervous and breathless.


    Not the others, but these big robots are very oppressive and intimidating, even though they are not equipped with any weapons at all.


    But when the robot came to Chen Xin, opened the cockpit and showed the pilot inside, Chen Xin''s face changed.


    He looked nervously at the driver''s distinctive right hand in the cockpit and asked nervously, "what''s the matter with you? Didn''t I let you stay at home? "


    "You ordered all Titans to come to the disaster area, including my one. As a pilot, I will come with you." Qin LAN jumps out of the cockpit, takes off her helmet and explains to Chen Xinru.


    Hear Qin LAN say so, Chen Xin helplessly shook his head, he some regret before why should agree to Qin LAN become Titan''s pilot.


    But since all the people came, he had nothing to say. He just said to Qin LAN, "in that case, you should follow the orders."


    With that, Chen Xin looked aside, watching him, Qin Lan''s vice mayor, and the rescue team leader. He sighed and explained to them, "these machines are called Titans. They are the products of the heavy-duty mecha project which is still in the experimental stage. At present, 27 experimental models of different models have been built.


    Each of them can lift a weight of about 10 tons with both arms, and the output of individual aircraft can reach 15 tons. It is a humanoid structure and is not easy to be restricted by the terrain. It can effectively assist the rescue team in excavating collapsed buildings and rescuing survivors. "


    "That''s great!" The deputy mayor had a look of surprise on his face.


    At first, he was still puzzled about these big robots, but now when he heard Chen Xin say so, he immediately understood what role these big robots played in rescue.The earthquake caused by the collapse of shelters and buildings, the biggest impact on the rescue is the debris after the collapse of those buildings.


    These fragments are large and small, and the smaller ones can be carried by several people together. After all, the rescue team is also equipped with exoskeletons. Even the civilian version, one person can lift hundreds of pounds of things.


    However, when encountering large pieces of building debris, even if there are exoskeletons, it is difficult to carry them. The weight is too heavy for several people to carry, sometimes there is not enough space for everyone to work together, which brings great trouble to the rescue.


    In the past, we could rely on construction machinery to use cranes and excavators to assist operations, but now the number of construction machinery is tight, even if all of them are put into the rescue line, it is still not enough.


    Although there are only more than 20 Titans in this group, it is undoubtedly a timely help for the disaster area, greatly enhancing the front-line rescue force.


    Chen Xin is also aware of this, just let Tang Tang will be all still in the experimental stage of Titan all transferred over.


    But Chen Xin didn''t expect that Qin LAN, who was asked to stay at home by him, would come with these Titans and give him an unexpected accident.


    However, since Chen Xin is here, she doesn''t want to ask Qin LAN to go back. Anyway, she is also the driver of one of the Titans. Although she watched Chen Xin build so many Titans at that time, she wanted to try what it was like to drive a big robot on the spur of the moment, but she was unexpectedly gifted.


    "This group of Titans will be assigned to you, but they are still experimental models. There may be some danger in safety. Pay attention to safety when using them." Chen Xin told the vice mayor and the rescue team leader nearby.

 Chapter 457

    Next to a collapsed ruins, a tall Titan is lifting a collapsed floor. It looks relaxed as if it is lifting a biscuit instead of a few tons of floor.


    Although Titan''s driver felt relaxed, he didn''t relax. Instead, he focused his attention and carefully lifted the floor to one side.


    Before that, some drivers were in a hurry because they wanted to save people. As a result, they moved away the collapsed building debris with some violence. As a result, these building debris broke up again, adding some unnecessary trouble to the rescue.


    Therefore, the rescue team also made clear Titan''s operation rules, and required to handle the rescue task with care to avoid causing unnecessary trouble.


    After Titan removed the collapsed floor, several airborne soldiers wearing exoskeletons quickly removed the remaining large building debris. With Titan''s assistance, they cleaned up the broken bricks and soon revealed a buried protective door.


    Although the protective door itself is very strong, and it is also made of steel plate wrapped with reinforced concrete, which has a very good protective ability, in the case of the collapse of the whole building due to the earthquake, the protective door is inevitably deformed, and even the bolt and rotating shaft of the fixed door are twisted, resulting in the door can not be opened.


    Seeing this situation, the rescue airborne soldiers did not find it difficult, nor did they take out any tools. Instead, after clearing the perimeter of the protective door, they yelled to the Titan standing behind: "the door is deformed and stuck, help to pull it open!"


    Titan''s driver said "received" and drove his car forward two steps to stand in front of the protective door. Then he controlled Titan to bend down, hold the protective door with both arms, and then stepped on the power pedal.


    The output of up to 10 tons made the whole Titan emit a crunching sound of metal friction. Even the broken bricks and stones at the feet of Titan were crushed even more, making people feel the power of the giant just standing beside.


    Before this amazing force, the deformed protective door didn''t last long even though it was strong. The whole door was pulled out from the original door frame with a bang.


    The deformed bolt and shaft were directly broken, and even the protective door itself was also deformed. The welding of the outer steel plate was broken, exposing the steel bar and broken cement inside.


    However, neither the Titan pilot nor the paratroopers on one side paid any attention to this. After the Titan threw the pulled down protective door aside, these paratroopers in power armor quickly took the rescue materials and entered the shelter behind the protective door.


    Titan was too big to enter, just standing at the door.


    However, the pilot did not idle, but controlled Titan to clean up the surrounding bricks and snow, and threw large pieces of building debris aside to sort out a passage.


    After all this, the two first airborne soldiers had carried a seemingly frozen survivor out of the shelter.


    "Come on, get this man to the rescue point!" Two paratroopers were running out with stretchers. Because of the power armor, they could run very fast even carrying one person.


    Titan quickly moved to the side, made way for the two paratroopers to carry people out.


    "It seems lucky that there are still people alive in this refuge." The pilot watched the paratroopers carry them away, and he couldn''t help sighing.


    Titan came to the disaster area and directly put into the disaster relief. With strong efforts, Titan dug up several collapsed shelters in a short time, just like now, but some of them were really unlucky. Even though the rescue workers tried very hard to save their lives, when the shelters were dug up, there were no living people in the whole shelters .


    The collapse caused by the earthquake directly killed many people, and the low temperature caused by the damage to the power and heating systems in the shelter made many of the wounded who were only slightly injured and could survive freeze to death.


    The whole sanctuary is like a huge grave, dead and miserable.


    However, for the rescue team, they have no time to be sad and miserable, there are more people waiting for them to rescue.


    So after digging up a shelter and confirming that no one survived, they only observed a minute''s silence, and then nervously put themselves into the rescue of another shelter.


    If there is no shelter for the survivors, they will be handed over to other rescue workers organized by the local government to clean up the remains.


    In fact, it''s not just that there is no shelter for the survivors. After the shelter is dug up, it is also handed over to the follow-up rescue workers for rescue and treatment. It''s just that the situation of the survivor just now is so bad that two airborne soldiers will carry out emergency treatment and send it to the rescue point.


    The follow-up rescue workers soon entered the shelter, searching for the survivors inside, while also carrying out a body.


    The paratroopers and Titans need to rush to the next excavation site to excavate and rescue the buried shelters.This is also the most efficient way at present. After all, Titan and construction machinery have a limited number, so they can only dig one and then go to dig the next, instead of digging one and staying in the same place all the time.


    Fortunately, in addition to the airborne soldiers who came to support, the rescue team and the people organized by the local municipal government also had exoskeletons. Although their efforts were not as good as those of the military version, they were still able to play a very important role in this case, saving many survivors buried under the ruins.


    The rescue point set up by the rescue team has become more and more busy and crowded as the survivors continue to arrive.


    At this time, four days have passed since the earthquake, and it is the third day for the rescue team to arrive in the disaster area. It is a celebration for the rescue team that a large number of survivors have been rescued, but their resettlement is a headache.


    The city where the Chenlong is located is the core area of the disaster area and one of the major cities in Southwest China. Before the disaster, there were more than 600000 people living in the city, and even after the disaster, there were more than 500000 people living in the city.


    But now the earthquake has caused varying degrees of damage to most of the shelters in the city. Even if the damage is not serious, the shelters can not live now, and a large number of rescued survivors can only be crowded in the tents temporarily built by the rescue team.


    With more and more survivors being rescued, tents will soon run out of use.

 Chapter 458

    The place where the rescue team set up the tent is a piece of flat ground sandwiched between two cracks. It is difficult to identify where it was originally, but because of the snow cover, it is a rare flat ground in the city at present.


    The rescue team also saw that the terrain here was relatively flat and relatively stable, so they chose this place as the rescue point and set up the resettlement area for the survivors here.


    Even the later airborne soldiers and Titan also chose to be near here. It can be said that this is the base camp for disaster relief.


    But the area of the flat land is not large. After the tents brought by the Chenlong were set up to accommodate the survivors, there was not much space left.


    "Is there any other place in the city where resettlement can be set up?" When the leader heard that the settlement had been overcrowded, he could not help feeling a headache.


    The rescue work is in a myriad of ways, and all kinds of things are piling up on his desk. He needs to be the leader of the team to deal with them. All kinds of things are too busy. Now there are new problems. It''s really hard for people to relax.


    "Most of the urban areas are affected by the earthquake, there is no relatively flat or stable large open space, it is not good to set up resettlement sites!" The vice mayor is also in a dilemma.


    The urban area is basically a crack formed by collapsed buildings and cracked snow. Even four or five days after the earthquake, there are still houses collapsing and snow falling in the urban area. The rescue team should be careful when they go deep into it. How dare they put the installation area in these places.


    But the city is surrounded by mountains, so it is difficult to find a flat place out of the city.


    "Do we have enough tents?" On the contrary, Chen Xin is more concerned about materials.


    "The tents are enough. When I came here, I took into account the need to resettle a large number of people affected by the disaster, and the inconvenience of transportation, so I brought a lot of tents." After hearing Chen Xin''s inquiry about the materials, the leader reported to him the current stock of materials: "at present, we only use about two-thirds of the tents we brought, and there are more than half of the other materials except food and drinking water. At present, medicine and heating equipment are the major consumers, and the others are OK.


    But now the resettlement sites are almost full. If we can''t open up new resettlement sites and the survivors can''t be resettled, there will be a big problem. "


    "I understand that, so the problem we need to solve now is to prepare a new settlement, right?" Chen Xin nodded and said that he understood the situation. At the same time, he asked the team leader and vice mayor.


    "Yes They both nodded and confirmed the answer.


    Hearing the two people''s answers, Chen Xin was silent for a moment, said "take a map" to the staff next to him, then held his arms and thought about it.


    The vice mayor and the team leader did not dare to disturb Chen Xinyi''s thinking when they saw that he was lost in thought.


    Both of them know Chen Xin''s identity. Seeing that he is thinking about this problem, they both feel that Chen Xin has a way to solve this problem. If this situation affects his thinking, it will be a big loss if the way he originally thought of flies.


    Soon the staff took the map and spread it on the table in front of the three people.


    The map is still printed before, so the urban planning and street signs on it are the same as they used to be, but generally speaking, they are still clear.


    Chen Xin stopped thinking after he brought the map. He took a look at the map, pointed to a blue lake area on the map and asked, "should it be frozen here now? Can we set up the settlement here? "


    Seeing the place where Chen Xin pointed, the vice mayor nodded and said, "this is the tourist area in the past. It should be frozen. But... "


    "But what?" Seeing the deputy mayor pause for a moment, Chen Xin asked him.


    "No one has been to this area since the impact of the meteorite. We are not sure about the situation there. We are not sure whether we can set up a settlement." Deputy mayor explained to Chen Xin.


    It''s also easy to understand. The lake marked blue on the map referred to by Chen Xin was originally a famous tourist attraction in the city, famous for its beautiful natural scenery. A few years ago, in order to protect the water quality of the lake area, the local government demolished more than 1000 inns around it to avoid polluting the lake area.


    Coupled with the cold weather after the impact of the meteorite, the whole lake area has been frozen for a long time, and few people in that area will pass.


    Chen Xin was not surprised. He looked at the leader and said to him, "send an airship to explore the situation. If there is no problem, set up a settlement in the lake area. Now it is estimated that the whole lake is frozen. It should be possible to set up a settlement on the ice."


    "I''ll send someone right away." The leader nodded at Chen Xin, turned around and gave orders to the staff.


    However, despite the order, the leader asked Chen Xin, "what if the lake area is not suitable for setting up settlements?"


    This is also a situation that we have to consider. Although theoretically the lake area is frozen and the whole lake surface can be regarded as a flat land, now after the earthquake, no one knows what the situation is at this time.


    However, Chen Xin was not worried about this. Instead, he asked them, "how many shelters have not been dug up? How about Titan? ""Relying on Titan, construction machinery and airborne soldiers, about 64% of the city''s shelters have been dug up, and about 21% of the remaining 36% haven''t been buried and don''t need to be dug up. Therefore, in general, the excavation work has been almost completed, leaving only other buried survivors to continue to search and rescue." The vice mayor knew the situation in detail, so he quickly told Chen Xin: "in addition, Titan is really easy to use. They are very efficient in excavating ruins. The rescue efficiency depends on them. However, two of them broke down during use, and others need to be repaired and maintained according to the driver."


    "It''s normal to work with high intensity and need maintenance in case of failure." Chen Xin nodded to show his understanding, so he asked the vice mayor, "is the rest of the excavation work done by construction machinery enough? Will it affect the search and rescue if Titan is transferred back for maintenance? "


    "It has a little impact, but it''s not a big problem." Said the deputy mayor after weighing it.


    Chen Xin was relieved and said to the vice mayor and the team leader, "in this case, take all the Titans back, and then take another 200 airborne soldiers to build a stable platform next to the current settlement, and build a new settlement."


    "Build a new settlement?" The leader and vice mayor were surprised by Chen Xin''s words: "how can we build this?"


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 459

    It is not impossible to build a stable platform beside the settlement to build a new settlement.


    Although there are two huge cracks next to the current settlement, the opposite side of the cracks is just a small piece of snow supported by a building wreck that has not completely collapsed. The area may be just enough to stop two small airships, which is not enough to set up a settlement.


    But if we want to build a stable platform on this basis to set up new settlements, there are still conditions and foundations.


    "Build a new platform? Academician Chen, what do you want to do? Is it possible to build a supporting structure with steel frames between cracks? " It seems that the vice mayor is quite familiar with the project. After a surprise at the beginning, he is also thinking about the possibility of Chen Xin''s idea.


    The cracks next to the resettlement site are not too wide. If steel beams are used to support both sides and then reinforce them, steel plates can be laid between the cracks to form a bridge that can pass through. On this basis, the snow on the opposite side of the crack can be expanded.


    It''s just that the construction volume of this scheme is too large. The vice mayor just estimated the required materials and man hours, and thought that this scheme is not feasible.


    Of course, Chen Xin did not want to achieve his goal in this way.


    "No, although we need to use structural support, it''s not between cracks, but to strengthen the area where we are now." Chen Xin said that there are nano molecules flying out of the wrist watch, forming a three-dimensional map on the table in front of him.


    The map shows exactly where the rescue site is now, and shows the surrounding cracks, several small flat areas that have not yet collapsed, and the building debris supporting these flat areas.


    Chen Xin didn''t pay attention to the surprise of the vice mayor and the team leader when they saw the stereoscopic map, but pointed to the surrounding small plains and said: "these plains are all due to the formation of snow, supported by building debris that has not yet collapsed. The area of the single building is small, and affected by the earthquake, there is a risk of collapse.


    Therefore, it is not realistic and safe to build a platform that can accommodate rescue points simply on the basis of these plains.


    Just now, Vice Mayor Zhao said that it is really a feasible method to build a supporting structure with steel beams. However, the investment in this scheme is too large and the working hours are very long, which is difficult to realize for the current rescue work.


    So my plan is to demolish all the buildings and demolish them completely, then level them, build a large area of flat land, and set up resettlement sites.


    Because the building debris that may collapse has been blown down, and it is in the form of debris accumulation. Even if there is an aftershock later, the risk of collapse or cracking here is not great, and it is a relatively ideal location for resettlement. "


    As Chen Xin said, the stereoscopic map projected on his desk also highlighted several building debris in red, and animated the process of building collapse, leveling by Titan, and finally building a settlement.


    Looking at the process demonstrated by the stereoscopic map, the vice mayor felt that the scheme was feasible, nodded and said: "I think it is possible. Although these buildings have not collapsed now, in case of aftershocks or strong earthquakes, no one can guarantee whether they will collapse, so it is a good choice to simply collapse."


    "I agree in principle with the plan of demolishing the building debris to level up an open space. Will the blasting here affect the stability of our current area?" The team leader evaluated Chen Xin''s plan and asked what he was worried about.


    Chen Xin nodded his head and explained to the team leader and vice mayor: "I have taken this into consideration. This is also the reason why I said that structural support and reinforcement are also needed.


    Before blasting, we need to build a supporting structure with steel beams to fix our area, and then blasting.


    In this way, even if there is an impact, the impact will not be very strong and within the controllable range. "


    "I think so. What do you think of Vice Mayor Zhao?" The team leader was convinced by Chen Xin and looked at the vice mayor with him, waiting for him to make a decision.


    At this time, the vice mayor did not hesitate or hold anything, nodded his head and said: "yes, we can implement this plan. I will coordinate the steel and explosives we need."


    Hearing that the vice mayor also agreed to the plan, Chen Xin showed a smile on his face. It''s really a happy thing to have a practical solution.


    However, he continued: "since we all agree, let Titan carry out the construction. It''s just right for them to do such things as construction machinery."


    In the original game of Titan fall, Titan is a kind of agricultural machinery, which was originally used for the agricultural production of human colonies on Mars.


    In short, it''s large agricultural machinery.


    But later, humans discovered the huge military potential of this large vehicle, which transformed it into a powerful war machine.For Chen Xin, he just wants to make a large vehicle. As for military or civilian use, he thinks it depends on where the country wants to apply it.


    In his opinion, if this kind of large vehicle is only used for war, it is really overqualified. During this period of time, Titan has played an obvious role in the rescue mission in the disaster area.


    They can not only effectively clean up the ruins, play more than ten times the work efficiency of ordinary workers, but also effectively improve the safety of construction.


    So for the rescue team in the disaster area, Titan is very popular, and everyone wants to have one.


    But now these big guys who are easy to use have all been transferred back, which makes the work of front-line rescue workers a lot of trouble, and makes many people have some strange guesses.


    But Titan''s pilots didn''t have these superfluous ideas. They had been told that they had a new mission long before they were transferred back.


    "Ah Xin, what''s Titan''s new mission?" Qin LAN is also a member of the Titan pilot. After returning to the settlement with other Titans, she finds Chen Xin and asks about the new mission.


    Although Qin Lan''s qualification as a Titan pilot comes from the back door, she really has this talent. At present, she is one of the most outstanding Titan pilots. With her special relationship with Chen Xin, she is naturally elected as the leader by other drivers.


    Although there is no official appointment, Qin LAN is still recognized by all drivers by her own ability.


    This time, Chen Xin suddenly transferred all Titans back from the rescue line. Of course, she told them that they had a new mission, but someone still encouraged Qin LAN to ask Chen Xin about the new mission.

 Chapter 460

    There are 27 Titans made by Chen Xin. Except one is Qin Lan''s car, the drivers of the remaining 26 are all drawn from the army by the state.


    The pilots were all army tank drivers with considerable vehicle driving experience. What they wanted was that they could quickly adapt to Titan''s driving.


    At that time, a total of 120 tank drivers were selected, of which 25 were elected and 25 were standby, a total of 50.


    At that time, a total of 25 Titan test planes were built. Later, two more were built by Chen Xin after testing and technical verification. Qin Lan was also a Titan pilot at that time.


    At first, these Titan drivers thought that Qin Lan was just pushed in through the back door, but in the subsequent training, Qin Lan''s hard work and talent soon made these people shut up, and then they convinced all Titan drivers with their own performance.


    It is precisely because of these performances that these drivers admit that Qin LAN is their boss.


    After all, Qin LAN has both ability and close relationship with Chen Xin. These drivers have not appointed a team leader. It''s not surprising that Qin LAN takes her as the leader after she is convinced.


    "Sister LAN, what did academician Chen say? What is our new task? " As soon as Qin LAN returned to the temporary residence of the Titan pilot, someone immediately surrounded her and asked her.


    Titan doesn''t need to refuel because of Chen Xin''s battery function, but it still needs maintenance for a long time.


    In the face of the driver''s inquiry, Qin LAN did not immediately explain. Instead, he waited for people to gather around him and said, "the rescue team needs to build a new settlement. Titan''s next task is to reinforce the foundation of the existing settlement, and assist in blasting several surrounding buildings to level the ground after blasting."


    "Let me tear down the house?" Several drivers around Qin LAN have strange expressions. Although they come to the disaster area to rescue people with Titan, they understand it very well and have no conflict with it. But now it''s strange for the original tank soldiers to let Titan really do the work of construction machinery.


    After all, the order they received at the beginning was to experiment with new vehicles. What they saw at Chen Xin''s research base were new military equipment such as new fighters, heavy machine armour and heavy power armor. Naturally, they also thought Titan was a new military equipment.


    However, what they are now allowed to do is construction work, which makes people feel that they are driving tanks to plow.


    Although it doesn''t contradict, it''s strange.


    Qin LAN certainly understood this idea and emotion, so she explained: "it''s not demolition, it''s blasting. Demolition is too slow. It''s direct blasting. Blow up the remains of the surrounding buildings and use them to level a flat ground to build a new settlement. Now there is not enough space for the settlement.


    If the workers are allowed to do this, it will not only take a lot of labor and machinery, but also time. If Titan is used, the efficiency will be much higher. "


    "I see. When will the mission begin?" The awareness of several drivers is naturally no problem. Just now, they just didn''t turn around. Now after Qin Lan said that, they are worried about whether they can carry out the task well: "these days, Titan needs maintenance. If the axle is broken."


    Two titans have been out of order before. Now these Titans do need to be overhauled, and some parts need to be replaced for maintenance.


    "So the comrades who have to work hard next night will work hard to repair all Titans overnight." Qin LAN saw that there were people in the servicing class among the people around him, so he also told Chen Xin another arrangement: "academician Chen asked that all Titans should be repaired and maintained before 12 noon tomorrow, and the reinforcement work of the existing settlement must start tomorrow morning. Is there a problem with the servicing team? Are spare parts and accessories enough


    "We have enough spare parts. This is not a problem." The monitor of the servicing class is also very concerned about the new task. At this time, he is beside Qin LAN. When he hears her ask, he answers with confidence: "most titans have no problems, mainly because of some damage to the shell and wear of parts. If you work overtime tonight, you should be able to finish it tomorrow morning."


    "It''s hard for you Qin Lan said hard work to the squad leader of the servicing class, then looked at the other drivers and said to them, "have a good rest tonight, adjust your state, and gather at 8 o''clock tomorrow morning for a Task Briefing."


    "I understand!" "Got it!" Around the drivers and servicing class agreed, and then scattered in twos and threes.


    A few drivers who feel that their bodies are in trouble are checking and repairing the bodies together with the people in the servicing class, while another part of the drivers seize the time to get ready for a rest.


    The rescue mission in recent days is very tiring for these drivers. They really need a good rest.


    Seeing this, Qin LAN didn''t go to rest with her, but walked towards her body.


    Qin Lan''s body is a more slender and short Titan, which is very different from other bodies.This is the second generation machine improved by Chen Xin according to the experimental and testing results after he made 25 prototypes. There are great differences in shape and structure.


    There are two second-generation machines in total, one is Qin Lan''s compact type, and the other is the enhanced type which strengthens the body''s output.


    There is no difference between the two machines, but the emphasis is different.


    As a matter of fact, none of the 27 Titans is the same as other bodies, each with different characteristics, in order to test the application of Titan in various situations.


    Qin LAN came to his car, opened the cockpit, inserted his identity verification key, and began the self-test of the body.


    Because of the short and compact structure of this aircraft, the cockpit is also relatively small. When Qin LAN sits in the cockpit, her body is tightly wrapped around her, and her feet need to be placed in the thighs of the aircraft. Unlike other aircraft, her feet are also placed in the cockpit.


    However, the corresponding is that the body has excellent flexibility. In many tests before coming, the legs of the machine are specially adjusted to anti joint structure, and the specially strengthened body has excellent jumping power and mobility, just like the agile assassin in the game.


    Qin LAN especially likes this machine. Although the power of the machine is smaller than other machines, the excellent flexibility makes Qin LAN know that if this machine is used in the battlefield, it will turn into the most dangerous assassin.


    Of course, this dangerous machine is just an easy-to-use construction machine at the moment, and it will have to move bricks at the construction site tomorrow.

 Chapter 461

    Next to the crevice, several titans are cutting grooves along one side of the crevice to place supporting steel beams.


    In order to avoid affecting the structural stability of the current resettlement site, it is necessary to reinforce the surrounding building debris.


    And the reinforcement method is also very simple, that is to build a frame with steel beams, fix the platform formed by snow where the settlement is located, and fill the frame made of steel beams with filler made of broken bricks and snow blocks, and then pour water to freeze it completely.


    In this way, the foundation of the settlement can be guaranteed and become firm and stable.


    It''s not a new idea. It''s just the old wisdom of sprinkling water to build a city that Prime Minister Cao used when he visited Xiliang more than 2000 years ago.


    However, the rescue team is still not as good as Prime Minister Cao. They can get water directly from the Wei River. They can only melt the collected snow first and then spill it to the place where they need it, and the speed must be fast. Otherwise, without sprinkling it, the water will freeze into ice at the low temperature of dozens of degrees below zero.


    With this method, Titan and the construction workers only need to dig out the groove for placing the supporting steel beam, and then insert the steel beam. They don''t even need cement, because the low-temperature frozen ice is strong enough to freeze the steel beam in the ice and snow.


    Of course, just as Prime Minister Cao splashed water to build the city was only a temporary emergency means, so freezing the steel beams in the ice by this means of freezing water into ice can only be a temporary emergency means.


    Although the ice and snow will not melt due to the warming of the weather at present, this is the earthquake stricken area. If there is an aftershock or a new earthquake, it is likely that the ice will crack due to the vibration. Therefore, this can only be used as an emergency measure to save time and construction materials under special circumstances.


    Relying on this rapid construction method and Titan''s far higher construction efficiency than ordinary employees, a steel structure frame was built soon, and even the filling materials filled into the frame had been buried in the construction process, making the location of the resettlement site firm and stable.


    After the foundation of the settlement is stable, the blasting work of the surrounding buildings will be arranged naturally.


    In fact, when Titan built the fixed frame, a construction team composed of airborne soldiers had already ventured into the still unraveled building debris to bury explosives for blasting.


    It''s a very dangerous job, not only because of the potential danger of burying explosives, but also because they enter the remains of buildings that have not collapsed after the disaster in Duolun.


    Although these building debris did not collapse for various reasons, the internal structure has long been unstable. No one knows whether they will collapse directly because of people entering and installing explosives.


    The collapse of the building debris itself is no problem, but when it collapses there are people inside, it''s really dangerous.


    Even if the airborne soldiers who enter to perform tasks have exoskeletons as protection, they can smash tens of thousands of tons of things on their heads. Even Titans can smash them, let alone human beings.


    Fortunately, these airborne soldiers were lucky. Although the work of going deep into the building debris to confirm the structure and place explosives was like dancing on a steel wire, they still completed the task without danger and prepared for blasting.


    "It seems that we need to study some weapons next time. In such a situation, it''s always too dangerous to bombard people directly and let people go in and plant bombs." Chen Xin, standing at a high place, saw the successful withdrawal of airborne soldiers who had entered the ruins of the building to place explosives. He could not help complaining at the same time.


    "How can a cannon demolish a house?" When the commander of the airborne soldiers heard Chen Xin say so, he couldn''t help joking.


    Just now, I have been worried about the soldiers who went in to place explosives. Now seeing them in the successful car, the commander is relieved. At least he is in the mood of joking.


    Just saying that, he could not help but sigh: "if there is a way to avoid the soldiers risking their lives to complete the task, it is certainly best! The duty of a soldier is to protect the people, but who is not raised by his parents? How can I not be distressed to see these soldiers risking their lives to carry out the task


    "That''s why there was a saying in ancient times that compassion didn''t take charge of the army. There was always a time when sacrifice and sacrifice were needed. Someone had to go." Chen Xin has the same feeling.


    In wartime, soldiers shed blood to defend their country. In peacetime, they also shed blood to make silent contributions to defend their country and people.


    If it was Chen Xin in the past, maybe he would only be moved. There is no way to do anything for these people, but now he can develop new equipment for these soldiers.


    Although it can''t protect the soldiers from danger, it can at least give them more protection in the face of danger.


    With this idea in mind, Chen Xin said, "I''ll think about what new equipment I can get in the future. It can at least increase the survivability of soldiers in this situation."


    Chen Xin thought of the heavy power armor that he was developing. This kind of equipment has excellent defense ability in the face of dangerous environment. It can not only resist the impact of explosives, but also ensure the survival probability of the wearer under the direct attack of small caliber artillery. It is very suitable to equip soldiers to deal with such dangerous tasks.However, Chen Xin himself did not participate in the development of heavy power armor. He just handed over several sets of prototype power armor to the research team and asked them to design an improvement plan. At present, there is not much progress.


    Now it seems that I may have to speed up my research.


    With such an idea, Chen Xin retreated to a safe place with the commander, and was about to explode. It was very dangerous to stand in front of him.


    In order to save time as much as possible, several buildings around were blasted together, which not only increased the difficulty of blasting, but also greatly increased the risk of blasting.


    Therefore, all the people in the settlement were required to stay in a safe place as far as possible and could not watch. As for the monitoring of the blasting, it was handed over to the ark Chenlong in the sky.


    "Five seconds, five, four, three, two, one! Detonate With a countdown, there was a loud explosion of explosives, followed by a tremor and a more violent roar.


    Chen Xin, who stayed in a safe shelter, clearly saw through the pre-set monitor that several building debris around him had a puff of smoke rising inside, and then the whole building began to collapse, just as he had planned, and turned into a pile of collapsed ruins.

 Chapter 462

    After several abandoned buildings were blown down, the next work was simple.


    It only needs to clear and level the ruins after the building blasting, which can be used to set up new resettlement sites and resettle the victims.


    While building new settlements on this side of the settlement, more survivors were sent over, and the airships that surveyed the lake area also completed their task.


    The results were not ideal.


    "Although the lake area was frozen, the ice surface cracked in a large area during the earthquake, and there were all large and small cracks on the ice surface. We tried to land down for investigation, resulting in further cracking and partial collapse of the ice surface, which was not suitable for setting up resettlement sites." The captain of the airship who completed the investigation task reported the situation to the leader and Chen Xin.


    At this time, only Chen Xinhe is in the command center of the resettlement site. The vice mayor is in charge of the overall construction and the resettlement of the survivors.


    Chen Xin was not surprised to hear the report from the captain of the airship, but he said with regret: "it''s a pity. If we can set up a settlement on the lake, we can send all the survivors in the urban area there. The area is enough to rebuild a city."


    "Fortunately, we have new settlements to use now, otherwise it''s still a big problem." It''s a pity for the team leader to hear the news.


    Fortunately, Chen Xin proposed the method of blowing up the surrounding buildings and clearing out a piece of open space. Otherwise, they still have to worry about how to place a large number of survivors.


    During this period, more than 90% of the shelters in the city have been opened, and the survivors have been rescued.


    It should have been a happy thing that all the survivors were rescued. However, looking at the dead and empty eyes in the resettlement site, as if they had been spirited away, they could only feel sadness and despair.


    Before the impact of the meteorite, this city was a tourist city with a population of more than 600000. It has picturesque scenery and pleasant climate in four seasons. It is known as the most suitable city for looking for poems and distant places.


    But after the meteorite impact, the surviving population of the whole city decreased to more than 500000, and nearly one fifth of the population disappeared in the disaster caused by the meteorite impact.


    The survivors were huddled in small shelters, struggling to survive.


    Originally, after the country received various kinds of scientific and technological support from Chen Xin, the days were gradually getting better. Although the post disaster reconstruction work was not progressing fast, it was also orderly.


    For the survivors in the shelter, this is also a glimmer of hope in the dilemma.


    But who would have thought that the earthquake would crush people''s only hope.


    Although the resettlement sites have been unable to accommodate more survivors, the rescue team has been fighting for a week. Less than 200000 survivors have been rescued from the ruins, and nearly two-thirds of the population has disappeared in the ruins.


    Although the rescue team also tried to clean up the ruins as much as possible, and the bodies of the victims in the shelters were collected and counted as much as possible, when the rescue team opened 90% of the shelters, only 190000 bodies were collected, and a considerable part of the bodies of the victims were still buried under the ruins and could not be cleaned up.


    These bodies are unlikely to be cleared for a long time.


    It takes a long time to clean up the collapsed cities. Most of the ruins are connected with the buildings themselves. Many of the destroyed shelters are not destroyed by the earthquake, but are crushed by the collapsed upper buildings. It is undoubtedly a huge project to clean up hundreds of thousands of tons of ruins.


    And those bodies buried under the ruins, if they are lucky not to be crushed, will be completely preserved in the low temperature of dozens of degrees below zero, and will probably not decay for decades or hundreds of years.


    Until in the future, when the dust dissipates, the sun shines on the earth again, and the ice and snow melt away, these remains may be able to see the sun again or perish.


    Except for the dead, the living also suffer.


    The vast majority of people are still immersed in the panic when the disaster comes, even if they have been rescued, many people still do not slow down.


    And this is good. After more people are rescued to the resettlement site and calm down, the first thing they think about is not others, but their relatives who are buried under the ruins and have not survived.


    The most grieving thing in the world is the separation of life and death. What the earthquake brings is that almost everyone in the city has suffered the loss of relatives and friends, and the whole city has fallen into pain and despair.


    Chen Xin understands this situation, as do the leader and vice mayor of the rescue team. However, at this moment, even the resettlement of the survivors has not been completed. How can they spare no effort to make people rekindle their hope for life?


    Even Chen Xin can''t think of any good way to deal with this situation.


    For Chen Xin, this is the second time that he has experienced such a situation that the whole city is in disaster.


    Last time in Linshi, relying on his exertion and the strong support of the state, the situation was finally turned around, but this time, he was somewhat unable to start.The disaster situation of the two cities is not the same. The temporary city is just buried by the snowstorm. The medical system can''t bear the surge of patients and collapses. As a result, the whole city can''t operate, but the infrastructure is not damaged.


    Disaster relief is only to solve the main contradiction, so that the situation can be quickly improved.


    But this city is totally different. Its situation is far more serious than that of the neighboring city.


    Almost all the refuges in the urban area can no longer be used. Most of the refuges have completely collapsed, and the ones that haven''t collapsed have been damaged to varying degrees. The reserves have suffered heavy losses, the industrial and agricultural production capacity has been completely destroyed, a large number of people have been lost, and the spirit of the survivors has suffered a huge blow


    So many problems are pressing on the city that even if people want to solve the problems, they can''t find a place to start.


    Everything needs to be solved, but also everything is not easy to solve.


    The disaster victims need to rebuild their habitable places, and the resettlement sites can only be temporary; the survivors who are short of food and clothing need more survival materials, and the transportation by ark is just a drop in the bucket; the industrial and agricultural production capacity is lost, and even if they want to rebuild, they must open up the railway transportation lines and re transport the raw materials and equipment; the loss of population


    Only by solving these problems, can these survivors who survived from the ruins rekindle their hope for life.


    Otherwise, it''s hard to live, and there''s no hope.


    Perhaps for ordinary survivors, these problems don''t need to be considered immediately. What''s more important is how to settle down as soon as possible and search and rescue the survivors that may still exist in the urban area. However, for leaders like Chen Xin, team leader and deputy mayor, we must start to consider these problems.


    The best way to solve these problems is to rebuild a new city.

 Chapter 463

    When Chen Xin and others were worried about the situation in the disaster area, the situation in Lucia''s capital was not much better.


    Although the arrival of dogs and pigs brings a glimmer of hope to Lucia in trouble, the country is so weak that it can hardly hold this glimmer of hope.


    Although Lucia is one of the top five blue stars, and her overall strength is not bad, this country itself is a sick tiger in the mire.


    In the era of suvia, the predecessor of Lucia, this country collapsed because of various social problems, and became Lucia and a series of countries. However, this kind of self collapse did not solve the various social problems left over from the suvia era, but made Lucia deeply troubled by these problems and in a more difficult situation.


    Before the disaster, suvia had disintegrated for nearly 30 years. Although the rich legacy left by Lucia barely maintained the dignity of the top five blue stars, and the efforts of the leaders also made the country struggle to get out of the quagmire, it still had little effect, and even the life of the people was not as good as that of suvia.


    In this case, Lucia is still involved in the fight against the meteorite.


    And it almost drained Lucia''s last breath.


    The country itself is extremely powerful. It has long lost the prestige of one of the two poles of the world that oppressed the whole of Europe in the era of suvia. The action of fighting back against meteorites can be said to be a gamble of almost all bets.


    If successful, Lucia may be able to recover through the way of post disaster reconstruction by relying on the credit of saving mankind and the people''s heart and national strength gathered by this event.


    Although it may not be able to make Lucia strong again, it can at least make things better at home.


    But this gamble failed, not only Lucia''s failure, but also the failure of all mankind.


    There is no winner. All countries are losers.


    And Lucia, also because lose too much, let his country almost usher in another collapse.


    When Yanguo''s aid arrived at the capital of Lucia after thousands of kilometers, although the city did not collapse, it was far more than Yanguo''s cold environment, shortage of various materials, and people troubled by cold and disease The capital of suvia, once one of the poles of the world, has become a desperate hell.


    The shelter under the capital subway station is already the best in the country.


    But even here, it''s not so much a refuge as a cellar full of starving people.


    More or less, people here can still get food that can keep them from starving, but that''s just starvation.


    Lucia is a high latitude country. The winter here is much longer than that in Yan country, and the agriculture is not developed.


    After the disaster, although the food supply was barely maintained by planting potatoes underground, many people starved to death.


    What''s worse than Yanguo is that the outdoor temperature of Lucia is lower than - 100 degrees, which is much worse than Yanguo. Outdoor activities can''t be carried out at this temperature. Everyone can only stay in the underground shelter.


    As a result, Lucia could not carry out post disaster reconstruction at all, so she had to try to continue digging underground to see if she could expand the refuge.


    What''s worse is that in the extremely cold temperature, the train can''t run, and the boiler can''t burn at more than 100 degrees below zero. The city is in a shortage of resources.


    At this time, the situation of Lucia''s capital is very similar to the fall of the winter home in the ice age. It is short of food and clothing, and the city is full of various problems.


    There is no stable supply of heating, coal and food!


    The arrival of the two ark of Yan kingdom is indeed a timely help, but what it can provide for Lucia is to pour a little alcohol into the firewood pile which has only been burned. Although it seems to be burning, when the alcohol is burned out, even the last ember can not be maintained.


    If you want to save this country, you have to inject new firewood.


    "You have seen the situation here. Lucia is in great need of Yanguo''s help now!" In the shelter of central subway station, Lucia''s leader met with the officials sent by Yanguo and told him frankly about Lucia''s dilemma: "only Yanguo can help Lucia now. As long as you are willing to help us through this dilemma, we are willing to repay your help with everything."


    At this time, the leaders of Western Asia have no room to negotiate with the country.


    The only thing he can do at this time is to put all that Lucia has on the negotiation table for Yanguo to choose, in exchange for help that can make Lucia live.


    "What do you need?" Maybe it''s the humility in Yan people''s bones. Even if they want to take all that Lucia can provide, Yan officials first asked about Lucia''s needs.


    After all, it''s all meat in the bowl. There''s no need to look ugly.


    "Food! drugs! Fuel! Even clothes! Lucia needs everything! We need everything to keep us alive! " Lucia''s leader kneaded his forehead helplessly and told the officials of the burning state of Lucia''s needs, even if it would expose Lucia''s weakness at the moment.However, Lucia''s leaders can no longer manage so much. Without any support, Lucia will perish.


    Before the disaster, of course, Lucia knew to be prepared. With the legacy of the suvian era, they did everything they could.


    However, the bad environment and the weakness of Lucia''s own national strength make them unable to do more things.


    Such as planting potatoes underground, Lucia certainly knows that this is the only way to get food after the disaster, but the weakness of her national strength makes it impossible for Lucia to have enough food to feed everyone.


    Now, Lucia''s leader can''t think about more. At the end of his life, he even thought about merging the whole country into the United Kingdom in exchange for the possibility that the country and its people will continue to survive.


    Compared with the hardship of Lucia''s leader, the official of Yan state was obviously more calm. He thought about it and said, "we have brought 50 tons of food and 10 tons of medicine. These are free gifts for you. You can deal with the emergency first."


    Hearing this, Lucia''s leader''s face was surprised.


    Although it''s really not much, it''s really a timely solution.


    "As for more aid, I need to contact China to make a decision. After all, the situation in Yanguo is not optimistic. The earthquake in Southwest China has brought huge losses to Yanguo, and we don''t have much spare power to help you." Yanguo officials have been keeping in touch with China, and of course they know the situation in China.


    At the moment, we are not only explaining the situation, but also bargaining with Lucia''s leaders.


    After all, Yanguo''s help is not really free.

 Chapter 464

    In the command room of the rescue team at the resettlement site, Chen Xin is studying how to rebuild the city against the map.


    At present, most of the survivors have been resettled in two resettlement sites. According to the statistics of the local municipal government, no more than 200000 people have been resettled in the two resettlement sites.


    In this disaster, more than 300000 people died.


    Through the efforts of the rescue team and the airborne troops later supported, about 210000 bodies were recovered from the ruins, and a considerable part of them were incomplete and unrecognizable.


    In total, there are more than 80000 bodies buried in the ruins of the city, unable to converge.


    In addition, more than 95% of the refuges in this city were scrapped, most of them completely collapsed, and a small part collapsed. The only remaining refuges also suffered from cracking, partial damage and other problems, and it seems that they can no longer be used.


    All the food and material production of the whole city has been interrupted. At present, 200000 disaster victims are relying on the materials brought by the rescue team to survive. Both the consumption and the gap are very large.


    In the short term, if we can''t restore the supply of materials and only rely on the ark for transportation, it will be difficult to ensure the survival of the remaining 200000 victims.


    At the moment, the city''s water supply and power supply have all been cut off, and the drinking water in the resettlement site is still supported by Chen Xin''s temporary water purifier, which melts snow.


    However, this is just the disaster situation of this city.


    The earthquake affected Sichuan, Yunnan and Guizhou provinces in Southwest China. The area and population affected by the earthquake were unprecedented in the history of Yanguo.


    Although the disaster situation varies from place to place, Chen Xin''s city is one of the most serious disaster areas, but the situation is similar.


    Lack of food and clothing, lack of water and food, although the country actively organized the rescue, but these are still the most important problems in the disaster area.


    In addition, the resettlement of the victims must be considered in the disaster area now. It is impossible for the victims to live in temporary tents all the time.


    Rebuilding cities and building new shelters, so that the victims can be resettled nearby, is of course the most ideal solution.


    But want to rebuild a city, even before the disaster is a huge project, in today''s Doomsday extremely cold environment, construction is extremely difficult.


    What''s more, in Chen Xin''s view, it is a time-consuming and laborious choice to rebuild the city on its original site. At the same time, there are still dangerous choices.


    In general, after a certain number of years, there will be subsequent earthquakes in areas where huge destructive earthquakes have occurred. The main reason is that the previous earthquakes have damaged the crustal structure of the area and become the energy release point of plate movement.


    Plate movement is non-stop, the subsequent energy concentration to a certain extent must be released, and the release process is generally earthquake, volcanic eruption and other forms.


    Although this earthquake in Southwest China is a release of energy, the impact of meteorite impact and super volcano eruption on plates and geological structures will last for quite a long time, and this is not the only destructive earthquake.


    Therefore, according to Chen Xin''s judgment, it is more prudent to move the residents in the geologically active areas to the areas with more stable geological structure, so as to avoid the disaster caused by another earthquake.


    But this kind of plan is too ideal, and it also needs more manpower and material resources.


    When the disaster came, Yanguo did move the population of several provinces along the southeast coast to inland areas. However, it did so only when the transportation, communication, production, construction and other forces were not affected, and because of the unprecedented concentration of the disaster, there was a threat of life and death.


    At present, security risks do exist in Southwest China, but it is not enough to remove all the population.


    What''s more, the country can''t move and resettle so many people in the three southwest provinces now.


    So now the only conceivable and feasible way is to build a new shelter nearby.


    However, it''s easy to say that it''s easy for the upper lip to touch the lower lip, but it''s not easy to really build a new refuge in this extremely harsh environment?


    In the past, only the north and south poles could compare with the present harsh environment, and the situation was even better.


    Not to mention anything else, at least the north and south poles will be able to see sunlight for half of the year, and the temperature will be warmer.


    But even before the disaster, countries around the world did not build any large-scale buildings in the north and south poles, only a few scientific research stations.


    Although this is to protect the ecological environment of the north and south poles, there is no large-scale ground breaking construction, but it is also because human beings do not have the necessary conditions for large-scale construction in Antarctica.


    Strong wind, frozen soil and extremely cold are all the problems restricting the construction.


    Even if Chen Xin can replace the construction machinery with Titan and greatly improve the construction efficiency, it is still not easy to rebuild a city.


    "Flatten all the building debris in the urban area to form a piece of land for urban reconstruction..." Looking at the map, Chen Xin is having a headache about how to rebuild the city and the shelter.Technically, it''s not difficult to level the ruins and the ground, just like Titan did before, it only takes a little time.


    To rebuild the city, it is not difficult to simply build surface buildings. Based on shelter and tent, the two existing settlements can be transformed into relatively livable settlements.


    Now the main problem of reconstruction in the disaster area is the shortage of materials. Without enough building materials, even if it can be constructed, it is impossible to build houses.


    If you want materials, you can only wait for the country to reopen the land transportation line. Otherwise, if you only rely on air drop or ark transportation, you will have exhausted all the transportation capacity just to maintain the lives of the victims in the disaster area.


    Moreover, in addition to the lack of materials, what makes Chen Xin more hesitant is the remains of the victims not cleared out from the ruins.


    This is not a small number, but the remains of more than 100000 victims.


    When the earthquake came, these 100000 people were either buried in collapsed shelters and did not escape at all, or they were killed when the surface buildings collapsed after they escaped. As a result, their bodies were buried under a large number of building ruins and could hardly be dug out.


    If the ruins are to be flattened, it is inevitable that the remains that have not been cleared out of the ruins will be destroyed.


    And after that, the new city will be built on the remains of the victims.


    Both morality and ethics make Chen Xin hesitant.


    Of course, the living are more important, but the dead are the 200000 living relatives and friends. Can they really accept the reconstruction of the city on the remains of their relatives and friends?

 Chapter 465

    "It''s really a difficult choice..." Facing the problems raised by Chen Xin, the vice mayor also felt very embarrassed.


    This is not an easy decision to make, nor is it an easy decision to make.


    Although 200000 people alive are very important, and their living and resettlement are the most urgent problems to be solved, 300000 people who died are also very important, especially 100000 of them were buried under the ruins.


    No one knows whether the 200000 alive will mind living on the remains of the 100000 people still buried under the ruins.


    There is no way for the remains of 100000 victims to converge. Even the survivors can understand this situation.


    After all, it''s lucky to be able to survive. There''s no way for the body to converge, and there''s nothing to do.


    But now, if we want to directly flatten the ruins and turn the remains still buried in the ruins directly into a part of the foundation, it is not easy to accept whether it is emotional or moral.


    "Yes, I''m embarrassed about that, too." With a wry smile on his face, Chen Xin explained to the vice mayor, "the resettlement of the disaster victims is an urgent task at present, and it is also the focus of your next work as the municipal government. However, this city itself is just a city built on the flat land around the lake, surrounded by mountains.


    The only flat land has been used up in thousands of urban development. There is no flat terrain around that can accommodate 200000 people. If you want to rebuild the city, you can only choose to flatten the existing urban ruins unless you build on the mountains. "


    Of course, the vice mayor knows about this. In fact, the biggest problem faced by the municipal government in the process of urban development in recent years is the shortage of urban land.


    This city is a city surrounded by mountains. The whole city is built around lakes. In the past, the scenery was really pleasant and the environment was beautiful. It was a very suitable place to live.


    In addition, the population of the city is not large, and it is indeed regarded as an ideal place for many people to come here to find their own poems and distant places.


    But that''s all in the past. In today''s long night and extremely cold environment, the mountains have become the shackles restricting the survival of the survivors.


    "Building shelters in the mountains Is it technically feasible? " The vice mayor considered it for a while and thought that it would be better not to disturb the dead when he had a choice.


    "It''s technically feasible, but you know the snow on the mountain. If there is an avalanche, it''s a big trouble to build a shelter on the mountain." Chen Xin still projected a three-dimensional schematic diagram through the nano molecules on his wrist, and explained: "if you really want to build a shelter in the mountains, you must dig out the snow, lay a foundation on the mountains or dig in directly.


    If the shelter is built directly on the snow, it is not only easy for the shelter itself to be buried by snow, but also the foundation is not stable enough. In the case of earthquake, it is very likely that the whole shelter will slide or even collapse due to avalanche.


    Therefore, for the sake of safety, the foundation must be laid in the mountain, or the mountain must be hollowed out to build a shelter in the mountain. However, if the construction difficulty is not mentioned for the time being, the engineering quantity itself will be very large. "


    Looking at the schematic diagram of shelter construction demonstrated by Chen Xin, the vice mayor''s face was a little bitter.


    If it is before the disaster, although it is also a big project, it is not difficult for him. As long as there is enough financial budget as support, such a project can still be built.


    However, at present, only the state can build such a large project, and local forces alone can not complete such a large project in any case.


    In fact, they can''t even push down the ruins to build houses if they only have their own local power.


    "I can''t make a decision on such a big matter by myself. I need to call a meeting of the comrades of the municipal Party committee to discuss it before I can give a reply." Although other major leaders of the city government have been killed, and now he is the top leader of the city as the vice mayor, the vice mayor has decided to hold a meeting with others to discuss this issue.


    "Let''s talk about it first. By the way, we can also have a survey of the victims in the resettlement sites to see if you can accept the flattening of urban ruins to rebuild your homes. I''ll think about other ways." Chen Xin didn''t say much, he just made a suggestion.


    The vice mayor nodded his head and said with approval: "this survey is definitely to be done. We will fully respect the opinions of the masses."


    With that, the deputy mayor left the command room.


    What kind of investigation are you doing, comrade In a tent at the settlement, city workers were held.


    This staff member is doing a survey, but it is obvious that the content of the survey is somewhat unacceptable. A middle-aged woman who has just been asked is already hiding her face and crying.


    This makes others feel uneasy, a kind of uneasy mood gradually spread, and the people in the tent can''t help whispering.Seeing this situation, the staff members quickly explained, "it''s a survey on post disaster reconstruction conducted by the municipal government. The municipal government is discussing the location of shelters for post disaster reconstruction, because there are some difficult places involved, so we need to conduct a public opinion survey."


    "Oh, why is this sister-in-law crying?" Holding the staff is a young man, looking at the woman crying in front of him, asking the staff.


    In his impression, this woman is a very strong woman. Although she lost her husband in the earthquake, she is still strong enough to take care of her young daughter and not be overwhelmed by life.


    But now because of an investigation, he cried so much, which really made the young man confused.


    With a sigh, the staff handed the questionnaire to the young man and motioned him to see for himself.


    The young man took the questionnaire, looked at the content above, and was stunned.


    It was written in the questionnaire: can you accept the city government to flatten the ruins of the city and build new shelters on the ruins?


    It is also noted that there are still about 100000 dead bodies in the ruins, which can not be converged and will inevitably cause damage to the dead bodies in the construction process.


    After reading it carefully, the young man felt that the questionnaire in his hand was extremely important, and at the same time, he understood why a strong woman would be made to hide her face and cry bitterly by a mere survey.


    Because he also lost his family and his favorite girlfriend in the earthquake.

 Chapter 466

    "Academician Chen, Vice Mayor Zhao asked me to give this to you." It has become the command room of Chen Xin''s office. A staff member of the municipal government handed a document and a letter to Chen Xin with a very solemn expression.


    Chen Xin took the things from the staff and was surprised. He asked, "what''s this?"


    "This is the result of the public opinion survey on whether to carry out the post disaster reconstruction work in the original urban area, and a letter from the people in the resettlement sites to the municipal government. After reading it, Vice Mayor Zhao asked me to pass it on to you. He said you should have a look at it." It seems that the staff have read this letter. They look sad and excited, but more proud.


    "OK, I''ll see it." Chen Xin seems to be aware of something, seriously nodded.


    After the staff left, Chen Xin opened the document in his hand, and the letter was put aside temporarily.


    It can be said that the result of the public opinion survey is in Chen Xin''s expectation, but it is beyond his expectation.


    More than 90% of the people who survived supported the reconstruction of the city and chose the option of rebuilding on the original site of the city.


    People support urban reconstruction, which is of course what Chen Xin expected. After all, Yanguo people have always said that people leave their hometown. Although migrants can be resettled to safer places, they are always far away from their hometown and become rootless duckweeds.


    If there is no way, who would be willing to stay away from the familiar place and living environment and go to a strange place?


    This is the result of the public opinion survey. Chen Xin was not surprised at all. Perhaps the only thing that surprised him was that 90% of the people supported the reconstruction of this road on the original site of the city.


    This is really beyond Chen Xin''s expectation.


    In particular, there is a special note at the bottom of this article, which is written with a pen, and this sentence also makes Chen Xin feel deeply shocked.


    This sentence is very simple, but when Chen Xin read it, he felt that every word was more and more important.


    "All the people of our city accept and understand the damage to the remains of the victims caused by the reconstruction work."


    In a short sentence, it seems very simple at first glance, and the meaning is also very clear. There is no misunderstanding or ambiguity.


    But the more so, the more you can feel the weight behind this sentence.


    It''s not one or two bodies or the simple consent of one or two people. It''s the hard and great choice made by the bodies of 100000 victims and 200000 survivors suffering from the loss of their loved ones under great grief and grief.


    The choice they made was to give up the remains of their relatives, not only to give up the collection of their relatives, but also to maintain the integrity of their bodies after death.


    Life and death matter, in the state of Yan, whether the dead can get peace after death is a very important thing.


    In the traditional culture of Yan state, we are very particular about the things behind the dead, not only death as life, but also whether the body of the dead is complete and whether they can be buried in the earth.


    If the dead can not be buried, or the body is incomplete when buried, it means that the soul of the dead can not get rest, and will sink into the world forever to bear suffering.


    This is a very taboo thing in the traditional culture of Yan state. Even though some feudal bad habits in modern society have been abandoned, the grief and respect for the dead relatives still make Yan people pay great attention to the peace of the dead.


    Even in modern society, it is still a taboo thing to be unable to collect the body of the dead and let it be exposed in the wilderness. It is also a great disrespect for the dead and the living.


    But now, the 200000 survivors of this city have chosen a very painful choice for them.


    Chen Xin did not dare to think about how the survivors, who suffered from the loss of their homes and relatives, made such a decision, and what kind of sacrifice it represented.


    Although the living people are more important than the dead, in the current environment and situation, it is the most important thing to let more people live.


    But it''s not just a cold body.


    They were living people not long ago. They are our most important relatives and friends. Now that they have passed away, it is a great blow to the living and an unbearable emotional pain.


    Now not only can''t collect their bodies, but also rebuild their homes on the ruins where their bodies are buried, and flatten the ruins where their bodies are buried. As a result, their bodies are incomplete and they can''t live in peace. This is not easy to accept in terms of emotion, morality and ethics.


    In fact, even if everyone is against flattening the ruins, Chen Xin thinks it is understandable.


    Now, however, the choice of 200000 people has been placed in front of him. They have chosen the most painful option for themselves.


    Chen Xin felt very heavy in his heart. He bit his lip, put down his opinion survey report, pinched the bridge of his nose, and then picked up the letter sent with the opinion survey report.Although I don''t know who wrote this letter and what content it contains, Chen Xin thinks it should have the answer he wants.


    With a sense of awe, Chen Xin began to read the letter.


    The letter is written on a piece of white paper. It can be seen that it is only a piece of paper temporarily found. There are even some stains on the paper, but it does not hinder reading.


    Because the content of the letter is not long, only a few lines.


    "The earthquake took away our relatives and friends. Their bodies were buried under the ruins and could not be collected. This is really a very painful thing."


    "But the dead are gone. Although it''s very difficult and painful to make such a decision, I''m still willing to agree with the municipal government''s decision to flatten the ruins and rebuild my home."


    "Although there are still remains of my family under the ruins, the living are more important than the dead."


    "Only by rebuilding their homes can more people live."


    "Flattening the ruins and destroying the remains is really unacceptable."


    "My family has left me forever. It''s really sad and painful, but I can''t let other people''s families leave them because of myself."


    "If I am also one of the victims, and if my body is still buried under the ruins, please take my body as the cornerstone of my new home. This is the only strength I can contribute."


    "Dead I have no hope, living people, please take my share of the future, build a new home."

 Chapter 467

    "All in silence!" Before the ruins, all the people, led by the vice mayor, Chen Xin and the rescue team leader, bowed their heads in silence for the victims under the ruins.


    After the results of the previous public opinion survey came out, the plan of flattening the ruins and rebuilding homes was finally passed.


    However, in deciding the construction scheme, the scheme with the least damage to the remains under the ruins was chosen.


    And before the construction began, the municipal government specially arranged the silence, hoping that the dead under the ruins could rest in peace.


    The weather under the doomsday is not so good. Today''s wind is also very strong. The snowflakes are blown up by the strong wind and crackle on the body, even making people unstable.


    But no one moved or dodged. Everyone was bowing their heads and praying sincerely for the victims under the ruins.


    Not only here, but in the settlement, all the survivors are doing the same thing.


    Everyone stopped their work and stood in silence and solemnity, lowering their heads and mourning for the dead.


    Even the wounded who can''t stand up are praying for those unfortunate people.


    On the Chenlong in the sky, the captain himself sounded the whistle, making a long sound, reverberating among the ruins that seemed particularly quiet, as if to comfort the souls of the dead.


    Strange to say, after the beginning of the silence, the fierce wind actually stopped.


    Just as God does not want this noisy wind to disturb the peace of the dead and destroy the solemnity of silence.


    The time of silence is not long, but the short three minutes make people feel very long. Many people shed tears because they think of their lost relatives.


    At this time, Chen Xin also bowed his head in silence for the victims.


    Just praying for the dead and wishing them rest in peace, Chen Xin is also thinking about how to prevent such a tragedy from happening again.


    Disaster itself is inevitable, in addition to preventive measures and early warning, people can not do much.


    Maybe by upgrading the system, based on some things in science fiction, we can finally upgrade the instruments that can control the crustal movement and make disasters disappear. But this is too far away.


    For Chen Xin now, a more practical way is to improve the existing construction technology, so that the refuges and cities can withstand the invasion of disasters.


    Thinking of this, Chen Xin can''t help remembering that the best way to prevent earthquakes is actually the island country in the East. After all, it is a country that has more than 1000 earthquakes a year, three times a day on average, even more frequent than three meals a day.


    Although most of the more than 1000 earthquakes are slight ones that are insensitive to the human body, we have to say that the island country has indeed accumulated rich experience in this respect.


    Perhaps I can learn from the relevant architectural experience and technology?


    Just as Chen Xin thought about this, the silence ended.


    Although the heart is still heavy, but the construction started as planned.


    Looking at the construction machinery began to flatten those still buried in the ruins of the victims, finally someone could not help crying.


    With this cry, it seems that the pressure and pain that everyone has suffered, as well as the sadness of losing their loved ones, have been released during this period of time.


    However, in the release of the pain at the same time, this cry seems to be the first cry of a newborn, indicating that the city will usher in a new life.


    Instead of staying on the construction site to watch the construction, Chen Xin returned to the resettlement site.


    During this period of time, although he did not go to the front line of disaster relief, and even did not participate in the disaster relief with the help of others, because of his identity, he had a more intuitive and real feeling about the disaster.


    For ordinary people, all they can feel is the passing of their relatives and the suffering they have suffered.


    The death of 300000 people in a city is a very intuitive number. For the survivors, their most intuitive feeling is that their relatives have died.


    This is enough to occupy all their minds, unable to think about what kind of damage this disaster has brought besides the death of their relatives and the destruction of their homes.


    However, for Chen Xin, the death of 300000 people is just the number of people killed in this city.


    His identity allows him to know from the country how terrible the disaster caused by the earthquake that affected the whole three southwest provinces.


    Chen Xin clearly remembers that when he was in college, the earthquake in Yanguo once caused the displacement of nearly 20 million people, the death of nearly 70000 people, and the disappearance of more than 17000 people. Ten counties and cities in the worst hit area, 41 counties and cities in the worst hit area, and 186 counties and cities in the general disaster area are the most destructive, the most extensive, the most serious disaster losses, and the most difficult disaster relief since the founding of the people''s Republic of China A big earthquake.


    However, this big earthquake is only stronger than that one, and the number of people killed in this earthquake has increased several times.When receiving the statistical data from the disaster relief teams all over the country, Chen Xin didn''t fall asleep all night. As soon as he closed his eyes, he seemed to be able to see the faces of countless victims and hear the cry of pain in his ears.


    If this disaster happened before the meteorite fell, it might not cause such huge casualties.


    However, after the meteorite fell, all people lived in shelters, and few people had outdoor activities. As a result, most people stayed in shelters that should have been used to avoid disasters when disasters came


    Those who can survive are lucky. They may be lucky that they didn''t stay in the shelter when the disaster hit, or the shelter where they were lucky didn''t collapse, or they escaped in time


    Whatever the reason, they survived, and they were luckier than those who died.


    But if this luck is compared with the misfortune of those who died, no one can be happy.


    This also made the atmosphere in the settlement very heavy during this period, and the heavy number of 300000 victims made everyone breathless.


    But now, the atmosphere in the settlement is not as heavy as it was a few days ago. It seems that the silence just now has also released the sadness in everyone''s heart, giving the atmosphere of the settlement a sense of hope.


    Feeling the change, Chen Xin felt better.


    Indeed, as the letter he received said, the dead are gone, and the lives of the living will continue.


    It doesn''t help to indulge in the past with sadness. Only with hope can we start a new life.

 Chapter 468

    The new shelter can no longer be built underground, and there is no need for air defense, so the plan of digging down is naturally abandoned.


    Now the new shelter adopts the same dome scheme of Chen Xin scientific research base. After all, there are few meteorites falling down, and the glass dome has no security risks.


    Moreover, the new shelter adopts this kind of architectural mode, which is more comfortable than the traditional spareribs mode, and it can also have larger internal space.


    In addition to the shelter itself, greenhouse, factory, power plant, waterworks and other supporting facilities are also under construction.


    For a while, although the whole city is still full of ruins, it has regained its vitality.


    Chen Xin originally wanted to stay behind to help the reconstruction of the disaster area. After all, with the system in hand, Chen Xin can greatly speed up the reconstruction of many things.


    But Chen Xin''s idea failed.


    As the railway line was robbed, a nuclear power train drove into the disaster area, which was responsible for transferring the victims who needed to be relocated to other places for resettlement. At the same time, it also brought the high-level order to let Chen Xin go back.


    "What''s the matter? Why do I have to go back all of a sudden? " On the train, Chen Xin asked an officer who was in charge of delivering orders.


    This is also what makes Chen Xin feel confused. Even if the high level has any requirements, it''s OK to send a government staff member or contact him through communication equipment. Why did he send an officer to give orders and arrange to take the train to go back?


    "It''s about state secrets." The officer took a look at Qin LAN sitting beside Chen Xin, and did not explain why.


    Qin LAN and Chen Xin go back together. Her Titan is now loaded on the train and will be transported back together, so she naturally accompanies Chen Xin.


    However, hearing what the officer said, Qin LAN immediately took the initiative to stand up, said "you chat" to Chen Xin, and then took the initiative to go out.


    After Qin LAN went out, the officer put the suitcase that he had been handcuffed to his wrist in front of Chen Xin. After opening it, he took out a document and handed it to Chen Xin.


    "It was brought back by the comrades who went to Lucia on the aid mission." The officer''s expression was very serious. After he handed the document to Chen Xin, he said, "the state has urgently organized experts to analyze it, but they have almost no clue. So the leader thought of academician Chen. I hope you can help with this."


    When Chen Xin heard the seriousness of the officer''s remarks, he took over the document and read it carefully. Only when he opened the first page, he raised his head in surprise and looked at the officer: "are you kidding me?"


    "Not really." The officer still looked serious and serious, nodded his head: "at first, when we got the information, we thought it was a big joke, but Lucia repeatedly assured the authenticity of the information.


    Moreover, the comrades who went there also saw the original documents. It''s true that the old documents of the suvian era are true. Unless they started to make fake documents from the suvian era, there is no doubt about the authenticity of the documents. "


    "That''s the most ridiculous thing I''ve ever heard!" Chen Xin threw the information on the table, and his whole face was full of disbelief.


    But after rubbing the bridge of his nose, he picked up the information again and read it page by page.


    Chen Xin looked at it very slowly, and the officer didn''t urge him. Instead, he patiently turned it over again after he had finished reading it all. Until Chen Xin put down the information, he asked, "academician Chen, what do you think of this?"


    "What can I think?" Chen Xin gave a wry smile and said, "unless I can go to the scene to see this kind of thing, I will only feel that you are joking, or that this is the setting of a science fiction game."


    With that, Chen Xin flipped the information on the table again, revealing the picture that made him laugh and cry.


    It''s a scan of a black-and-white photograph that looks a little blurry, but what''s in it is still clear.


    However, it is precisely this clarity that makes Chen Xin feel that it is unlikely that this thing really exists.


    But the seriousness of the officer and the assurance he mentioned about Lucia made Chen Xin a little suspicious of the existence of this thing.


    When it comes to suvia, everyone will think of the era when it competed with the two poles of the Federation for hegemony, and the most representative of which is the series of anti sky black technologies full of Soviet style.


    Whether it''s the female harrier ground effect vehicle, mig-105 space fighter, don-2n radar array, SVL high-speed train, K7 heavy bomber known as Caspian monster


    Or the Truman bus card, which seems insignificant, but makes the Federation lose face, is the glory created by the red giant bear.


    After the disintegration of suvia, many confidential information was also lost, including many black technology projects that were once the brains of the high-level leaders of suvia in the era of the federal cold war.


    These plans are either fanciful or too avant-garde. Although they are abandoned for various reasons, there are many feasible plans that are abandoned because of high cost or poor practicability.For example, the spherical tank, LPL flying submarine and 1k17 laser tank are all practical and feasible, but they were abandoned for various reasons. This time, when Yan sent people to Lucia, they got these precious materials.


    However, these materials are also mixed with things similar to the materials presented in front of Chen Xin, which make people feel too whimsical and unrealistic at first glance.


    For example, the carrier rocket carrying passengers, the giant hydrofoil cruise ship used across the Atlantic


    As well as the thing in front of Chen Xin.


    Chen Xin scratched his forehead and asked the officer, "where is this thing now? Did they really make it? "


    "The East and the West are in Siberia. At that time, the suvians built two prototypes and tested them for many times in Siberia. After the final design, they made a finished product. The three prototypes are now in Siberia, and they are in the experimental base built by the suvians at that time." The officer explained to Chen Xin that although all the information was written in the materials, since Chen Xin asked, he would answer.


    Chen Xin nodded, then asked the officer, "so besides transferring the victims, the real mission of this train is to send me to Siberia to see this thing?"


    "Yes, we will first send the victims to nearby cities for resettlement, and then go north along the railway line to take you to Siberia." The officer nodded for sure.

 Chapter 469

    The wheels rolled forward and collided with the steel track, making the sound of scuffing.


    Sitting by the window, Chen Xin looks at the scenery outside the window, and there is still a document in front of him that makes him feel like a bad joke.


    But now he has believed the truth of this matter, and he also believes that in the Cold War era, the suvians really opened their minds and made this thing.


    However, although he believed in the existence of this thing, Chen Xin still found it hard to accept. After all, this thing is really amazing.


    Although Chen Xin has also considered making similar things, Chen Xin thinks that the bottom line of this thing is that he has the system upgrade as his bottom line, so he dares to say that he can make it.


    However, at the beginning, the suvians had nothing to do with it. They only made it by relying on their excellent industrial strength and engineers'' brain holes in the sky. The difference between the two is very different in the real sense.


    After taking a sip of the cold boiled water on the table, Chen Xin decided not to think about it for the time being and planned to go to the dining car to get something to eat and change his mood.


    This train is one of the nuclear power trains which were officially put into use after the country''s nuclear power locomotive service.


    Unlike the experimental nuclear power train that Chen Xin once saw, this train, though also dragging 27 cars, does not have so many fancy functions.


    Of the seven carriages, 20 are long sleeper carriages for carrying victims, while the remaining six are functional carriages.


    A water purification car is responsible for providing drinking water for the whole train, and the main source of water is the purified snow along the way.


    I''ve seen a new dining car. It''s the same model as the old one.


    The two reserve cars carry food reserves. Because of the nature of the task, they need to provide a large number of meals, so they all carry shelter food, and there is no fresh food.


    The shelter food without excessive management is good enough for the victims on the bus.


    As for the remaining two cars, one is a freight car, which is now dragging Qin Lan''s Titan and some other goods carried by the car, while the last one is a scientific research car, which is specially prepared for the later mission to the north.


    The formation of this train is very interesting. Of course, the most important nuclear power front of the whole train is in the front. Behind the front is Chen Xin''s carriage, followed by the scientific test carriage, freight carriage, water purification carriage, dining car and two reserve carriages, followed by 20 long sleeper carriages.


    According to the officer who came to meet Chen Xin, this train is only temporarily responsible for transporting the victims. If there is an emergency, they will leave the 20 long sleeper cars carrying the victims and move forward light.


    In this regard, Chen Xin did not feel that there was anything wrong when he learned that the victims would be towed away by other vehicles.


    Passing through the carriages one by one, I came to the dining car. Because it''s not a meal, it seems a little lonely here.


    This kind of dining car is very different from the dining car on the train in the past, because it is not a passenger train, and it has to provide a lot of food for the whole car, so there are no tables and seats in the car.


    The whole dining car is a huge kitchen, which is made of all stainless steel integrated cooker. A total of five chefs are responsible for making or heating a large amount of food at the same time, providing meals for the whole car.


    "Academician Chen, what do you need?" Seeing Chen Xin enter the dining car, two chefs on duty greet him and ask him if he has any needs.


    As staff members, although they do not know the task of going north after the train, the food reserve and special carriage specially prepared for Chen Xin on the train, which are different from others, are enough to make these staff members realize the importance of Chen Xin.


    "I''m a little hungry from the information. Do you have anything to eat now?" Chen Xin is also not polite, put forward his own needs to the two chefs on duty.


    The two chefs on duty were on duty in the dining car to prevent the staff on the car from missing the meal and wanting to eat, not to mention Chen Xin''s special treatment in the car.


    So after Chen Xin opened his mouth, the two chefs were busy nodding their heads and preparing food for him.


    Because there was something that the staff might need to eat, and Chen Xin had special supplies, the food he needed was ready soon.


    After taking over the food prepared by two chefs, Chen Xin takes the food back to his car.


    "Academician!" However, as Chen Xin passes through the scientific research carriage, he comes across an officer who is delivering orders. He seems to be checking the equipment in the carriage.


    This makes Chen Xin a little curious about him. After all, the officer has been wearing a military uniform and doesn''t look like a scientific researcher.


    However, Chen Xin didn''t stop to talk with him. He just nodded and went through the research carriage and back to his own carriage.Although this car is short, it is relative to other standard length cars and the 20 long cars behind.


    In the past, according to the national standard, there were 60 hard sleeper cars and 40 soft sleeper cars. Each car had 11 cabins and was equipped with toilets and bathrooms, ranging in length from 24.4 meters to 26.6 meters.


    Now the long carriages are lengthened. The capacity of a hard sleeper carriage has increased to 90 people, and the length of the carriage has also reached 35 meters.


    Although Chen Xin''s short carriage is called a short carriage, it is actually 18 meters long. There are toilets, bathrooms and separate kitchens in the carriage. It is also designed with one large room, two small rooms, three rooms, a living room that can be used as a meeting room and a communication room equipped with communication equipment.


    The two small rooms in the carriage are designed to serve as guest rooms or guards for important passengers, while the large room even has independent bathroom. In the past, it may only be a little luxurious, but now, it is very luxurious.


    If necessary, the train can get rid of all the cars behind and only take this car forward at the fastest speed to ensure the safety of the important passengers on the train.


    Back in the car, Chen Xin sits down in the living room, ready to enjoy his own food, but while he is eating, Qin LAN comes out of the room.


    "Why don''t you sleep a little longer? It''s still early. " Chen Xin looks at his watch and asks Qin LAN.


    Qin LAN poured himself a cup of hot water and drank half a cup at a time. Then he said, "I can''t sleep, and I want to talk to you about something."

 Chapter 470

    Qin LAN seems to have something very important to say to Chen Xin, but she was interrupted when she was about to say it, so that she didn''t say it.


    Chen Xin wanted to ask her again sometime, but the train soon arrived at a station, where all the 20 long cars were unloaded. They and the victims would be sent to the resettlement place by other vehicles.


    Chen Xin''s nuclear power train was reorganized, with four more cars. After replenishing supplies, it went directly north.


    Originally, Qin LAN should have gone north with Chen Xin, but she didn''t do so for some reason. Instead, she and her Titan were unloaded along with the freight car, ready to go back to the scientific research base.


    This makes Chen Xin very strange, but under Qin Lan''s insistence, Chen Xin still agrees her request to go back.


    After all, the reason given by Qin LAN is also very normal. Her Titan has some faults in the previous disaster relief work and needs to be transported back for repair.


    In the absence of Titan, it would not be helpful for her to go north with Chen Xin, so there was no need to go to Siberia with her.


    So after the train was reorganized, Chen Xin continued to go north, while Qin LAN and her Titan were sent back to the scientific research base.


    As for the four carriages of the new group, one is armed, one is maintenance and two are troop carriers.


    The reason why there is a troop carriage is that it''s going to Siberia.


    It''s a famous cold and bitter place, and even before the disaster, most of it was primeval forest and no man''s land.


    In the history of Lucia, there has been a good tradition of banishing criminals to that land.


    From the December Party members to the old nobles, the eradicated criminals, the prisoners of war in the Patriotic War and so on, although most of the land is no man''s land, there are also a large number of poachers and criminals, as well as the local aborigines and wild animals.


    In addition, in the era of suvia, a large number of people with ideals came to this land to build their own motherland and develop this vast and rich land.


    But with the disintegration of suvia, Lucia was unable to continue the development of Siberia. These idealists either left or drowned in their former ideals, struggling in this land until they lost hope and chose to die.


    In Chen Xin''s memory, he remembers reading a report that there was a small city in Siberia that was originally built by the development of Siberia in the suvian era. In the suvian era, it was prosperous and beautiful. Although the environment was bad, people were full of hope.


    However, with the disintegration of suvia, it gradually became deserted. People living here gradually lost hope and lived with vodka all day long. They were intoxicated and paralyzed with alcohol.


    It is said that people there would get drunk every day, and then they would not go home. Instead, they would find a cold place to sleep in the snow.


    If you don''t wake up the next day, you are lucky to be frozen to death in your sleep and don''t have to continue to live hopelessly.


    If you''re not lucky enough to get up again, keep getting drunk and find a colder place to repeat.


    In addition to these, it used to be an important weapon Experimental Zone in the era of suvia. No one knows how many things suvia had hidden in that vast land in those years, even the lucians themselves do not know.


    They only know from the information they have, that in those years, suvia had tested a large number of weapons and confirmatory technologies on that land, built countless secret bases, and left behind a large number of military equipment.


    You can''t go to a place like this without enough hands and weapons.


    Even if Siberia is colder than it used to be, it''s more unfit for human survival.


    As for taking the engineering maintenance car, it is prepared to receive the things mentioned in the documents.


    After all, it was built before the disintegration of suvia. Even though the technology of the suvians is reliable, suvia itself has been disintegrating for more than 30 years. No matter how well it is preserved, it needs to be inspected and repaired before it can be put into operation again.


    Although for Chen Xin, a click on the system upgrade can make that thing completely new.


    When the train goes northward, it can''t talk about how fast it drives. After all, it''s extremely cold environment. There is snow and ice on the rail. If it drives too fast, even the train will overturn.


    And that makes the journey a little longer.


    According to the statement he asked the staff on the train, it takes about four or five days to walk in Yanguo, and there are four or five days to go after leaving the country.


    Considering some problems that may occur on the road, and the fact that the capital of Yan Kingdom has been submerged by the sea, the original route can not be taken any more. We need to go around Xinjiang Province to go abroad and enter Lucia through Kazak. It may take two weeks for this trip to reach the destination.


    Chen Xin really cares. Anyway, there is food and drink in the car. The car specially prepared for him is very comfortable. There are other people in the car, so it''s not boring.It is almost impossible to choose another way to go to Siberia. Even before the disaster, the main way to go to Siberia was by railway.


    What''s more, the place they are going to is the secret military base in the era of suvia. Except for a secret Railway built in the same era, there is only a simple military airport, which has been abandoned for many years and can''t be used.


    Going there by train is the only viable option at present.


    If it is before the disaster, the scenery of this line should be said to be very good.


    From the southwest to the northwest of Yanguo, then to Kazak in Central Asia, and finally to Siberia in Lucia, the landscape along the way changes with the rising dimension, so you can enjoy the natural scenery.


    But now the window is dark, except for a little bit of snow illuminated by the light from the window, nothing can be seen.


    It really made the journey a bit dull.


    However, compared with the underground shelter, it is still a very meaningful thing to be able to cross the old mountains and rivers by car and train.


    Even if you can''t see any scenery along the way, it''s still an interesting thing to guess where you are and imagine what the surrounding scenery should be like as the train goes on. It''s enough to kill the leisure time on the journey.


    What''s more, everyone has a lot of work to do along the way, which is not boring and boring.

 Chapter 471

    When it comes to artillery, many people are familiar with it. This kind of heavy attack weapon, known as the God of war, has a long history and is destined to dominate the theme of war from the moment it was born.


    The earliest artillery can even be traced back to the spring and Autumn period of Yan state more than 2500 years ago. At that time, a kind of military weapon called "Yi" appeared, which is the ancestor of today''s various artillery.


    It''s just that the early so-called cannon, to a greater extent, was used to fire stone bombs or incendiary bombs made of pine and other things. It was not so much a cannon as a huge stone thrower.


    However, with the development of history and the invention of gunpowder, the true artillery had its rudiment in the Song Dynasty. At the latest in the Yuan Dynasty, the true artillery, the smoothbore gun, was invented, which gave birth to all the cannons used in human history.


    In the history of the great artillery, a powerful weapon appeared.


    No matter who wants to win, he can''t refuse the ultimate plan to win.


    With the help of the ulban cannons, the Turks ended the Millennium glory of the Roman Empire, and since then there has been no fortress that will never fall.


    Relying on the concentrated use of artillery, Napoleon conquered Europe, and since then, artillery has never been absent from every famous battle in human history.


    Even on the other hand, in every famous battle since the large-scale use of artillery, has there been no artillery?


    However, as the barrel of the gun becomes thicker and more powerful, its weight becomes heavier and heavier. Naturally, the mobility and use of the gun are also restricted.


    Because of this, the Uban cannon was the largest caliber gun ever made by human beings for a long time.


    Until modern times, with the development of industry and science and technology, there were super cannons whose caliber broke through the sky, and the way to transport them was no longer the traditional way of relying on human or animal power to transport, but to carry these big guys onto the train.


    From this, the most powerful gun used in war in human history, train gun, was born.


    This kind of super gun relying on the rail movement is undoubtedly the largest caliber super weapon ever used by human beings in the war. In the first World War, Germany used to bombard France with the Paris cannon, the Gustav cannon and Dora cannon in the Second World War, and the mass-produced K5 (E) train gun, etc


    Although this kind of super gun is very troublesome to move or set up, it has to be said that once it is launched in war, its power is incomparable.


    Gustav''s cannon once shot through a 10 meter thick reinforced concrete fortification, leaving a crater as big as four football fields. It can be said that nothing can resist its shelling in the war.


    But this kind of cannon is too slow and troublesome to move, and the caliber of the mass-produced train gun is not big enough.


    So is there a kind of cannon that can not only meet the requirements of mobility on the battlefield, but also ensure the caliber of artillery?


    The answer is yes, and someone has built it. The result is what Chen Xin mentioned in the document he received, the ultimate weapon of land war built in the suvian era - the land cruiser.


    To tell you the truth, when he first saw it, Chen Xin seriously felt that it was made up by some science fiction writer, because it was too exaggerated.


    After the end of World War II, the suvians seized a large amount of German technical data, including naturally the train guns that had been brilliant in World War II and the Gustav heavy guns that had not been completely destroyed.


    At that time, suvia did not attach much importance to this, but sent some weapon experts to study and try to imitate its own train gun.


    However, with the confrontation between the Soviet Union and the Federation and the escalation of the cold war after the war, the suvians felt that they needed a land-based weapon that could withstand the invasion of the Federation from the east coast in Siberia. Naturally, the train gun became one of the key objects considered by the high-level officials of the Soviet Union at that time.


    After all, there is only one Bering Strait between the easternmost end of the suvian territory and the westernmost end of the federal territory, and the narrowest part of the Bering Strait is only 35 kilometers.


    The suvians could have set up their super cannons here and then bombarded the federal territory directly.


    Although it is of little significance to do so, it is necessary if the Federation intends to cross the Bering Strait and attack suvia by land.


    It''s just that Siberia is deserted, and it''s very troublesome to build a railway to deploy train guns.


    So when the weapon experts in suvia designed a 600mm caliber cannon with two rails, the plan was rejected.


    The first is that mobility is still not enough, because missiles and rockets have been put into use at that time, and train guns have become less popular and practical.


    Second, the senior management of suvia felt that the caliber and power of this device were not enough, especially at that time when suvia had already lit up its nuclear technology and train guns were no longer popular.So the weapon experts in suvia completely released themselves and created a second improved model.


    They replaced the train wheels of the trailer at the bottom of the gun with tracks, and made a super chassis with 16 tracks, an 800mm caliber super cannon with a range of more than 70km, and equipped it with specially designed nuclear shells.


    Satisfied with this, the high-level officials in suvia ordered the trial production of a door, and carried out the test firing at the Siberian weapons testing ground.


    But it''s not really useful. After all, it''s too heavy.


    Even with 16 tracks, it can barely walk on land, but in Siberia it can only drive normally after the soil freezes in winter, and snow will seriously interfere with its progress.


    When the temperature is higher and the ice and snow melt, the muddy frozen soil is enough to make it sink into the mud.


    The key point is that this thing is powered by a steam turbine, which needs a lot of fuel to move.


    So after the test launch, the senior management of suvia put forward new requirements to the weapon experts, hoping that this thing can be more practical. They can make it smaller and less powerful, but it should be practical and can be mass produced.


    This time, the requirements are very reasonable. The weapon experts in suvia have narrowed their brain holes a little, so a land cruiser that can be put into practical use in a real sense has been built, and two prototype vehicles and a subsequent improved one have been completed.


    This is what Chen Xin got from the document. It is a "Super Tank" with a length of 74 meters and a weight of 307 tons. It is equipped with a double 305 mm caliber main gun and uses a small nuclear reactor as the power source.

 Chapter 472

    The train is still moving forward.


    As a nuclear power train, although it is not as exaggerated as the snow country train with perpetual motion machine as energy in the novel, it can run forever, but it can also run for a long time under the condition of sufficient supply, without considering stopping to replenish fuel and so on.


    But even so, when the train entered the capital of Xinjiang Province, it stopped at the station for the last material supplement before leaving Yanguo.


    "We can''t get supplies until we get out of the border to Lucia. Although Kazakh allowed us to pass through, they couldn''t provide supplies." In the reception room of the carriage, the officer is explaining the schedule to Chen Xin.


    "Is the railway still working in Kazakhstan and Lucia?" Chen Xin doesn''t care much about the schedule. He is more concerned about whether the railway can still be used.


    Kazak and Lucia are not like Yan state. In order to ensure the domestic material transportation, the comrades on the railway front have been maintaining the railway track. In order to ensure the smooth flow of the railway line, they have made great efforts and sacrifices.


    But abroad, Chen Xin is not sure whether they can ensure the smooth flow of the railway.


    In particular, it is doubtful whether this kind of cross-border route can be guaranteed to be unblocked when it is difficult for all countries to protect themselves and there is no international exchange.


    However, the officer was not worried about this. He said to Chen Xin, "academician Chen, you can rest assured that the engineering vehicle we brought can carry out simple maintenance on the railway. If necessary, we can build a section of it by ourselves, which will not affect the journey."


    "Yes? Then I''m relieved. " When Chen Xin heard the officer say this, he nodded. It seemed that he was really relieved.


    Although for Chen Xin, this kind of thing is not worth worrying about. When it comes to the time of need, whether it''s changing the train into a track to drive directly, or repairing the original road section, or simply building a railway by himself, he can do it.


    However, there was a question that worried Chen Xin. He turned to the officer and asked, "I remember that the railway in Lucia is not the same width as the railway in our country. After we go there, shall we change the track?"


    This is inevitable. After all, for strategic reasons, Lucia''s railway tracks use wide rails, unlike the international standards used by Yanguo and other countries.


    "Yes, after we entered Lucia." The officer definitely nodded, but his expression was somewhat helpless: "Lucia said that we can use their station and wheels, but these things need to be operated by ourselves. There is no one there."


    Hearing what the officer said, Chen Xin could not help holding his forehead and said feebly: "their station should have been completely covered with snow, right? How do we use this? Do you have to spend months digging out the station for them first? "


    Relying on the surging power of the nuclear powered nose, there is no need to worry about the snow on the orbit, and it can be hard opened by the snow remover.


    But the station completely buried in snow is the same as the railway station that Chen Xin handled in Linshi. It''s not something that can be dug out by manpower.


    If you need to dig out their station to change the track in Lucia, it will be too difficult.


    "Yes, we are also worried about it. Although lucians said that they had put all the wheels into the warehouse before the disaster and provided the map of the station, we just need to clean up the warehouse and the cranes on the platform, it is still very troublesome." The officer''s serious face was sad.


    It is necessary to change tracks. Otherwise, trains with different gauge are easy to derail. Now the snow weather will easily cause the whole train to overturn.


    However, Chen Xin is not so worried about this problem as an officer. If he really wants to face this situation, he can directly upgrade the train and change the gauge. It won''t cost him much to survive.


    So Chen Xin said, "you don''t have to worry about this. If you have to dig a railway station to change the track, I can use the engineering vehicle to change the track directly. It''s not a big problem."


    "Directly change the track with engineering vehicle? Is this kind of thing troublesome? " The officers did not doubt whether Chen Xin could do it. They just worried about whether things would be very troublesome.


    In this regard, Chen Xin just showed up and said with a smile, "it''s not necessarily more troublesome than digging out the whole station."


    "Well, I''ll trouble you, academician Chen." The officers did not continue to worry about this. They took the engineering vehicles on the road just to cope with all kinds of possible situations.


    After putting this question down, the officer looked at the document in front of Chen Xin and asked him curiously, "academician Chen, do you have any ideas about this thing?"


    "Ideas? My only thought now is "what does the country want this thing for?" Chen Xin also took a look at the monster on the file with the double pack 280, and shook his head helplessly: "if there was such a thing in World War II, it was really a weapon of war.


    But it''s the 21st century. Aren''t missiles and rockets popular? You don''t need 280 guns in the Navy? What can I do with it? The chassis can be disassembled and modified to make it useful. Other things are really useless. ""This..." The officer''s face was embarrassed. He picked up the document without any trace and turned to the last few pages. Then he asked Chen Xin, "didn''t you read academician Chen''s part?"


    Chen Xin saw the pages that the officer turned to, picked his eyebrows and said, "take off the gun barrel and change it into an all terrain vehicle? That''s not a bad idea, but has the person who put forward the idea ever considered the cost? "


    "Cost problem?" The officer was stunned. He didn''t think of that.


    "It''s a product of the cold war. It''s still unknown whether it can be used after so many years. It needs to be overhauled thoroughly and its parts need to be replaced, especially if it uses nuclear power." Chen Xin pointed his finger on the document and said to the officer seriously: "even if we don''t say anything about it, we''ll treat it as the technical force of suvia. It can still be used now, but it''s half a century old.


    Even if it can still drive, many of its parts need to be updated. Instead of repairing this old antique and driving it back, I''d better go to Lucia and get the information and then rebuild a new one.


    And I don''t quite understand, what''s the point of turning this thing into an all terrain vehicle? Even if the military needs it, it can''t use such a big thing, can it? So what is the real purpose? Or is there something I don''t know about it? "

 Chapter 473

    Train gun may indeed be a very powerful battlefield support weapon during World War II, but after nearly a century of vigorous development of science and technology after World War II, the science and technology mastered by mankind has already undergone earth shaking changes.


    In front of the missiles, rockets, bombers and even more sci-fi space-based weapons equipped by the modern military, the train gun is just like a large target.


    Taking the military equipment in the hands of the modern army as an example, it only needs two armed helicopters to dismantle a train gun which was a sharp weapon in World War II.


    So although the Land Cruisers of the suvians really look very powerful and terrible, they are actually obsolete in history.


    In fact, after this thing was really made, the senior management of suvia realized that it was not practical, so they soon gave up the idea of mass production.


    Otherwise, with the craziness of the Soviet Union and the Federation during the cold war, after the successful development of this killer carrying two 305 thick tubes, there was no reason for the suvians to equip it on a small scale.


    As for the fact that the suvians can''t build so many tanks, just imagine that their production plans were all based on ten thousand tanks, from which they could spare a little to build a hundred and eighty such land cruisers. In terms of the industrial strength of suvians, there is no problem at all.


    However, the suvians did not choose to mass produce the Land Cruisers. They even built only two experimental aircraft and one mass production model, and then sealed them up in the secret military base in Siberia and did not use them again.


    It takes a lot of resources and time to produce the final product, but it is a waste of time to seal it directly.


    However, in the Cold War era, it is not inconceivable that a technology has invested a lot of resources in research, but found that the results have become out of date, which is very common in arms research.


    Especially after the Second World War, the rapid development of military science and technology led to the formation of many military equipment.


    However, some can make do with it, and some can only discard and seal the scheme.


    Moreover, it is not that the suvians did not consider using the three Land Cruisers. When the relationship between the two countries was the worst, and even the border conflict broke out, the suvians considered using the three monsters that had just been sealed up at that time to participate in the border conflict.


    However, because of the long distance, the three Land Cruisers can not be transported by train, and can only go to the conflict area by their own power, which takes too long on the road.


    At that time, it was just a border conflict. Although the two sides used force, they still kept restraint and did not break out a full-scale conflict. Although the suvians did consider using this device, they finally gave up the idea.


    This matter has become a dusty file, put half a century no one knows.


    It was not until this time that lucians took out all their sealed family belongings in order to get the aid of Yanguo that they found the record about this matter from a suvia filing cabinet full of dust.


    Also let Yan know, when the border conflict, the suvians actually intend to use this kind of big killer.


    Fortunately, it''s all in the past. Suvia has been disintegrated for more than 30 years. It doesn''t mean anything now. It just makes Yanguo interested in the three Land Cruisers.


    As for why we need to get these three Land Cruisers back, it''s not as simple as transforming them into all terrain vehicles.


    Although the top management does plan to transform the three Land Cruisers into all terrain vehicles after they are transported back, there is a deeper purpose in addition.


    The three Land Cruisers used nuclear reactors as power sources. With the nuclear technology of suvia at that time, it was really possible. After all, they also built mobile nuclear power plants at that time, but they were abandoned because of the city cutting incident.


    However, according to the top secret information of unsealing, Chen Xin learned that at that time, the suvians only used the nuclear reactor on the second test machine and the mass production model. As for the power source of the first prototype machine, the suvians did not use the nuclear reactor.


    Instead, they used an energy crystal that the suvians had accidentally acquired, which was the real purpose of Chen Xin''s trip to Siberia.


    If three Land Cruisers can be brought back, they can be brought back. If they can''t, they can do a good job in surveying and mapping. If they can get the drawings, they can build new ones themselves. However, the energy crystal used on the prototype is something that the senior management is really interested in and wants to obtain.


    It is precisely because of this that the high level sent such a team to Siberia in order to bring back this energy crystal comparable to a nuclear reactor.


    After all, according to another top secret information given by Lucia, the volume of this energy crystal is only the size of a fist, but it can stably output the energy of a small nuclear reactor of that era.


    If it wasn''t for the fact that the scientists in suvia used every means to copy this thing, or even to understand its principle and material structure, they wouldn''t have wasted it on Building Land Cruisers.This also makes Chen Xin very interested in this thing, because according to the research data of the suvians, although this crystal is continuously releasing energy, its mass has not been reduced. Even if the suvians used the most sophisticated instruments for measurement and long-term observation, they did not find any change in the quality of this thing.


    This is very contrary to common sense, because in the process of transforming matter into energy, the greater the energy released, the more the mass of matter will be reduced. In theory, the mass of matter will also be reduced if energy is continuously released.


    However, this crystal has been studied in the hands of the suvians for quite a long time and has been continuously releasing energy without any mass reduction, which obviously does not conform to the laws of physics.


    In this case, there are two possibilities: one is that the crystal absorbs new substances to supplement itself in the process of releasing energy, forming a cycle; the other is that it is actually a very high-density energy crystal, which has been releasing energy in the way of "low power". Although it releases energy, its mass is reduced too little, according to the view of the suvians at that time It can''t be found by means of measurement.


    As for what the situation is, Chen Xin can''t be sure now. Only after he really starts to use it, can he judge what it is.


    And because of the appearance of this thing, Chen Xin finally became interested in this journey.

 Chapter 474

    After crossing the border between Kazakhstan and Lucia, which was deserted even before the disaster, Chen Xin''s train arrived at the planned station on the border.


    However, just as expected, they encountered the problem of changing tracks. Not only that, the so-called station had already been completely buried by snow. To complete the operation, they had to clear out two rails of different widths. Not to mention, they also had to remove the cranes, warehouses with wide gauge wheels and platforms used for the operation from the snow Dig it out.


    Fortunately, this is nothing for Chen Xin. He instructs the soldiers on the train to help clean up the two tracks. After finding the wide gauge wheels, he asks them to build a temporary gate between the two tracks with an engineering vehicle.


    Then Chen Xin let their train through the gate to the wide track, and directly upgraded their train with the wide track wheels found by the soldiers.


    With the upgrading of Chen Xin''s order, the spacing between the wheels of the train was widened to a suitable width, which quickly solved the problem of changing tracks. It was not necessary for soldiers to dig out the crane on one side, and then spend several hours to lift the carriage onto the wide rail road.


    And after that, they moved on again.


    Only after entering Lucia, the road is not as smooth as in the territory of Yan and Kazak.


    The thick snow all over Siberia, together with the disaster caused by the impact of meteorites and the lack of maintenance after the disaster, made a lot of railway tracks here damaged, which made Chen Xin often need to walk for a period of repair. They wasted a lot of energy to get through the vast snow and reach their destination.


    This is a typical no man''s land deep in the great forest of Siberia. Before the disaster, there was no road leading here except a secret military railway which could lead to the secret military base deep in the forest.


    In order to isolate the unexpected situation, some people inadvertently set foot in it and discover the secrets kept by suvia.


    Before it was sealed up, the suvians built a small town here to serve the soldiers and scientists in the military base. The town has a series of living facilities such as stations, schools, hospitals and so on, ensuring that the soldiers and scientists living here can get all the life needs in the small town.


    However, with the sealing up of the military base, all the soldiers, scientists and staff who once lived in the small town have been evacuated, and the small town, together with the sealed military base, has been sealed up in the depths of the Siberian forest.


    If it is before the disaster, the scenery here is quite beautiful.


    With a clear suvian era of various small town buildings, surrounded by lush virgin forest covered with rolling mountains, there is a beautiful lake beside.


    It can be said that in the Cold War era, life here was extremely comfortable without the threat of war and the noise of big cities.


    Of course, there may be less recreational activities. However, there were not many recreational activities in that era. It was not a big problem that life was simpler.


    Now, however, everything here has been covered with thick snow, almost no trace of human life can be seen.


    "According to the information given by Lucia, our current location should be the railway station, which is located in the west of the town. In the center of the town is an office building, where there is an underpass leading to the military base. We can go through the underpass connecting the office building from below the railway station." The officer opened the town map provided by the lucians, pointed to the names marked in Russian on the map and explained to Chen Xin.


    Chen Xin took a look at the map and found that he could not understand the Russian language on it. He did not pay attention to the map any more. He just said to the officer, "since you are in charge of the operation command, you can make up your mind, but be careful. It''s hard to guarantee that there were no defensive measures left when the Soviet Union withdrew."


    "Please don''t worry. We''ve brought special explosive disposal engineers this time. There won''t be any problem." The officer nodded solemnly, which he also took into account, so he not only brought the EOD engineers, but also made them wear the heavy EOD mecha specially developed by the military.


    When Chen Xin saw two engineers appear in EOD mecha, he couldn''t help picking his eyebrows and asked in surprise, "is this the heavy mecha I designed?"


    "Yes, after analyzing the heavy machine armour designed by academician Chen, the military weapon experts have designed several other models according to the heavy machine armour, one of which is the EOD type. However, it is still in the testing stage. We borrowed these two for this mission, which can be regarded as helping the design Department to carry out actual combat testing." The officer explained to Chen Xinru, while at the same time, two heavy explosive disposal machines also entered the inside of the excavated railway station and found the passage to the underground.


    This is also a major feature of the architectural design in the period of suvia. Underground passages are built for air defense.


    In those days, this design was still very effective. In case of air raid, ground personnel could hide in air raid shelters and underground passages to effectively resist the damage of air raid.


    It''s just that this kind of design seems to be inferior nowadays. After all, the air raid shelters under most civil buildings are not deep enough from the ground. With the penetration of modern bombs, hiding in such old-fashioned underground passages or air raid shelters is likely to be directly buried by the collapsed soil layer.Of course, civil buildings are not likely to get big bombs. If it''s just ordinary shelling or bombing, the buildings on the ground may be flattened, but people underground still have a chance to survive.


    After two heavy-duty explosive disposal machines entered the underground passage, the explosive left over from the suvian era was discovered.


    It''s also a routine operation. After all, what''s sealed up here is an important military base. It''s normal to leave some security measures for civilian facilities connected with the base to prevent people from sneaking in.


    However, they are all things left over from decades ago. Many layout methods and corresponding elimination methods have long been well known. With the help of the explosive disposal machine armour, two explosive disposal engineers quickly demolished the explosives, allowing other soldiers and staff behind to enter the underground passage smoothly.


    After walking through the town along the underpass, they went a little further to reach the destination of this journey, a secret military base sealed up by suvia for more than half a century.

 Chapter 475

    As the explosion-proof door of the dusty military base opened, a decadent wind blew out from inside.


    However, Chen Xin and others did not care, but directly went in.


    It''s not that they don''t know that the underground facilities that have been closed for many years should wait for the air to drain out before entering. It''s just that everyone is wearing fully enclosed protective clothing.


    It was known that two of the three land cruisers were nuclear powered, and according to the records provided by the lucians, none of the three Land Cruisers had removed the power source at the time of storage.


    That is to say, apart from the prototype that uses energy crystals, the other two Land Cruisers also have nuclear reactors on board.


    In view of the possible radiation pollution and leakage after being released for so many years, everyone dare not carelessly put on the fully enclosed protective clothing which can isolate the radiation pollution, so as not to accidentally get contaminated with excessive radiation and explain themselves here.


    "Sure enough, there was a radiation leak, but it didn''t look serious." Inside the base, the Geiger counter in the hands of a staff member has been ringing, but the frequency of the sound is not fast, and the radiation dose is not dangerous.


    Hearing this, the officer told the soldiers who were waiting: "search the whole base, pay attention to safety!"


    "Yes A soldier in charge of leading the team answered and divided the soldiers who entered the base into several teams and began to search.


    And Chen Xinze, together with the officers and several staff members, under the protection of several soldiers, walked towards the depth of the base.


    As for the source of radiation, we all know that it comes from the sealed three Land Cruisers, and we don''t need to look for it. The map provided by lucians has already clearly marked the sealed place, so they just need to follow the map.


    As for the reason why someone was sent to search the long sealed base, it is because according to the information provided by the lucians, there are not only three Land Cruisers sealed up here.


    As a base for conducting secret military experiments and testing various kinds of equipment, there are many things left over from the suvian era.


    There are not only all kinds of experimental equipment and test records that were tested here in those years, but also many other things left over from the initial evacuation.


    After all, according to the information provided by the lucians, this place was abandoned after the disintegration of suvia. There were a lot of materials and information left behind during the evacuation. These things are of high value. Even after decades, they are still good harvest and worth taking away.


    In addition, they have another job is to eliminate the possible danger in the base.


    In any case, it is an old base that has been sealed up for decades. No one knows whether there has been any change after so many years, whether the things that have been stored for decades have expired or become any dangerous goods.


    So when the soldiers search the whole base, they are also checking these potential security risks.


    When the soldiers searched the base and gradually found some harvest, Chen Xin and others had come to a huge warehouse inside the base and saw three Land Cruisers sealed up.


    Although Chen Xin has seen the photos and clearly understood how big the object is, the photos and standing in front of the object to feel its greatness are two completely different effects.


    The land cruiser, which is more than ten meters high, is covered with a huge dark green felt cloth. It is covered with dust. Under the searchlights of several soldiers around it, it looks like an earth mountain with a humble face.


    Although they are covered with felt cloth, it can''t hide the ferocity and dignity of the steel giant under them. Two flat 305mm gun barrels jack up the felt cloth. If you don''t distinguish them carefully, you may even think it''s a hill.


    Even if it''s a flat barrel, the space under the barrel and felt still allows Chen Xin and all of them to stand in, and they don''t feel crowded.


    "Turn it off, all three." Chen Xin looked at the three Land Cruisers lined up and motioned to lift the felt.


    After hearing Chen Xin''s words, several soldiers lifted up the blanket covering the land cruiser and even climbed up for convenience.


    With the movements of several soldiers, the felt cloth which has been covered with dust for more than 30 years is gradually pulled away, and the dust rises with the movements of the soldiers. For a moment, people''s sight is also affected, but the same thing seems to add some momentum to the iron beast which has been seen under the felt cloth for more than 30 years.


    "What a spectacle! I can''t imagine how shocking this thing would be if it was fired! " Chen Xin uses the flashlight in his hand to shine on the gun barrel, looking at the thick gun barrel that can be directly drilled into by a person, he can''t help feeling.


    Not only Chen Xin, but other people also have the same idea when they look at the gun barrel that a strong man can''t hold.


    In modern war, although artillery is still used as an old but very useful heavy weapon, with the development of human science and technology, after we have more efficient and direct means, the caliber of artillery is not bigger and bigger, but smaller and smaller.Of course, this does not reduce the power of the artillery, but makes it more and more difficult for people to see how spectacular the firing of the artillery with a caliber of more than 150 mm is.


    At present, however, there are six Super cannons that can only be installed on battleships or large fortresses in the past.


    "By the way, is there a shell on it? Can you give it a shot? " Chen Xin looked at the officer beside him and asked him excitedly, "since I''ve come here to try to take this thing back, it''s right for me to check whether it can still be used?"


    "Well, this..." The officer felt a bit embarrassed and didn''t know whether to agree to Chen Xin''s request.


    The high level asked Chen Xin to take things back, referring to the energy crystals on the test plane and the chassis of the three Land Cruisers. As for the gun barrel, it is actually very despised. After all, the launching box with a DF missile is not as good as this thick tube?


    The time for two big guns to fire once is enough for DF missiles to fire once, and the whole target is leveled.


    But even so, the officer himself wanted to see what the 305 mm cannon looked like.


    He hesitated for a moment, looked at the land cruiser in front of him, and then asked Chen Xin, "academician Chen, is this a necessary test?"


    "Well, since we need to take it back, it''s better to take it back with the whole tail. If the barrel doesn''t work or there''s something wrong with it, it''s better to take it down now, so as not to take up space when we take it back." Chen Xin shrugged his shoulders and said.

 Chapter 476

    It is said that it is necessary to carry out artillery test, but in fact, it is not an easy thing to launch one.


    Although the three land cruisers were all intact when they were sealed up, it is still unknown whether these monsters can move after more than 30 years of the disintegration of suvia.


    Thirty years is enough time for a baby to grow up, get married and have children, so that a piece of metal is rusted to a certain extent, and two pieces of metal ingots placed together can even be completely bonded together.


    After 30 years of experience, the parts of these three land cruisers are aging and rusting, and the radiation pollution and leakage of nuclear reactors. These are all problems. We need to make a thorough inspection and overhaul before we can determine whether they can be used.


    Fortunately, it was sealed up in a secret military base with perfect preservation facilities. Although the technology is more than 30 years old, it has not caused much damage to the three Land Cruisers for at least 30 years.


    However, in addition to the prototypes that use energy crystals as energy sources, the nuclear reactors of the other two land cruisers are inevitably damaged during the idle period of more than 30 years. Radiation leakage and pollution have turned these two Land Cruisers into huge sources of radiation pollution.


    Although their metal shells prevent radiation leakage to a certain extent, the internal radiation level of the two Land Cruisers has exploded. Even if they go in wearing protective clothing, they will be instantly contaminated with a lot of radiation, which is enough to endanger people''s lives.


    So after measuring the radiation values of the two nuclear powered Land Cruisers, both Chen Xin and his officers lost interest in getting them back.


    They want usable equipment, not two large radioactive sources.


    However, it can''t be left in this way. Although there is no danger and the leaked radiation will not lead to a tragedy of the level of qiecheng, it''s better to deal with it.


    Although people can''t enter, robots and instruments can still enter the interior of the land cruiser for inspection.


    "It seems that the nuclear technology of the suvians at that time was really excellent. The nuclear lighthouse could still operate after serving for so many years. Needless to say, the two nuclear reactions were only slightly leaked after being stacked for more than 30 years. The quality is really poor." Looking at the pictures taken by the robot, Chen Xin couldn''t help praising the technology and quality of the suvia era.


    In fact, not only is the nuclear reactor technically excellent, but the quality of things in the suvia era is generally very good. Even in this military base that has been sealed up for more than 30 years, after finding the power supply, Chen Xin''s staff restarted the generator and restored the power to the whole base, while the lighting facilities more than 30 years ago still can operate normally.


    "That said, the reactor is no longer working, is it? Are we really going to deal with this? " The officer frowned as he looked at the radiation sign on the picture.


    It''s not that he doesn''t want to deal with these two nuclear reactors. This kind of thing that has been leaking nuclear radiation is very dangerous. Even now, he doesn''t worry that someone will accidentally dig them out or take them to do something dangerous. It''s also a threat to put them here all the time.


    But now the nuclear radiation inside the two Land Cruisers is already fatal, and it is impossible for them to let the soldiers and staff risk their lives to deal with it.


    After all, it''s not on our own territory. There''s no need for people to sacrifice.


    "It''s still necessary to deal with it. This is Siberia. In case the radiation leaks out and spreads to the sky, it will blow southward along the air stream, but it will blow to Yanguo." Chen Xin also doesn''t want to deal with the historical problems left over by the suvian era for the lucians, but this thing may still affect the state of Yan, so he still hopes to deal with it properly.


    However, Chen Xin is not a person who can take human life to fill this kind of pit. He thought for a moment and said, "my nano armor can resist nuclear radiation. I''ll go in and deal with it, dismantle the reactor and seal the reactor.


    Now I''m going to check first to see if I can dismantle the reactor. Have you got the drawing of this thing? Does it say how to change the reactor for this thing? If you don''t have it, you have to tear it down. "


    With that, Chen Xin started the watch in his hand. A layer of nano molecules covered his body and turned it into a set of heavy power armor.


    "Academician Chen!" The officer quickly grabbed Chen Xin''s wrist, stopped him and said, "this can''t do! You are more important than anything else! Even if all of us have filled in, we can''t let you in! "


    With these words, the officer called out to the soldiers around him and put Chen Xin away.


    Although it is said that the power of nano armor can easily break away, Chen Xin did not do so. He just told the officers, "I will not be in danger. Nano armor can completely isolate nuclear radiation. It is much safer for me to go in than for you."


    "No! Even if you let a soldier wear your nano armor, you can''t go in! " The officers were very persistent and firmly opposed to all the possible dangerous behaviors of Chen Xin.


    Seeing the officer''s insistence, Chen Xin had to give up the idea of going in himself. After thinking about it, he said, "in this case, don''t let people go in and take risks. I''ll switch the nano armor to the remote control mode, let the armor go in, and I''ll stay outside to control it."In fact, nano armor doesn''t have such a function. Chen Xin wants to upgrade it temporarily so that nano armor can have remote control mode.


    With that, a green light flashed across the whole armor, and these nano molecules flowed down from Chen Xin like mercury, and then molded into a silver human shape in front of him, and then turned into armor on the surface.


    Some of the nano molecules left in Chen Xin''s body converged on his head to form a pair of brain wave control glasses.


    Seeing this scene, the officer let the two soldiers who had blocked Chen Xin let him go.


    While controlling the nano armor to go inside a land cruiser, Chen Xin asked the officer beside him: "do you have neutron absorber?"


    "We didn''t bring it, but the suvians prepared it. We found a lot of boron and leaded cement that could still be used in the warehouse." The officer reported to Chen Xin that according to the information found, the materials were transported after the city cutting incident.


    "Looks like the suvians were going to seal the pile?" Chen Xin was surprised at this, but it''s not something worth paying attention to. He just said to the officer, "let people be prepared to seal the reactor and prepare for radiation protection. If we can''t take the reactor out directly, we may have to take the whole thing apart."

 Chapter 477

    The disposal of nuclear reactors is far more troublesome than Chen Xin thought.


    Nano armor smoothly entered the interior of the two Land Cruisers, and also checked the condition of the nuclear reactors. These two small nuclear reactors were used on nuclear submarines in the suvia era, and their quality was not bad. Even after so many years, only slight leakage occurred.


    However, even if the nuclear reactor is only slightly leaked, it is also a very serious accident, especially when the leakage is likely to have lasted for quite a long time and the whole base has been filled with radiation, it is more and more necessary to deal with it, but it is also more and more difficult to deal with it.


    The shell of the reactor has been corroded by radiation. As a result, the whole reactor has been deformed. It is not possible to remove it with the original normal installation method.


    In addition, when the suvians first designed the land cruiser, they didn''t want to change the reactor every other time. As a result, if they want to dismantle the reactor, they have to open a big hole in the whole land cruiser.


    Just as the whole deck needs to be cut to replace the reactor for a nuclear powered aircraft carrier, the shell of a land cruiser needs to be cut to replace the reactor.


    After all, it''s usually just a matter of replacing the nuclear fuel. After a reactor is installed, it can even be used to scrap the equipment for decades. Who would think about dismantling the reactor?


    But now, this problem has become what Chen Xin has to face. How can he remove the corroded reactor from the thick armor of the land cruiser.


    "We can cut it from under the chassis. The bottom of this land cruiser is A-type structure, which is mounted on four crawler chassis, so the bottom space is enough." A technician with the team pointed to the structural section of the land cruiser on the drawing and said, "we can cut a hole from this place, and then make a cement sarcophagus here. After removing the core of the reactor, we can directly put it into the sarcophagus through the cut hole, and then seal the sarcophagus as quickly as possible!"


    Chen Xin took a look at the drawings, simulated the structure of the land cruiser with nano molecules, then demonstrated it for a while, nodded and said: "this scheme can indeed reduce the harm and impact to the minimum, I think it can."


    Because we have found all the design drawings of the land cruiser, we also have a comprehensive understanding of Chen Xin and others.


    According to the design of the suvians, there are three ways to dismantle the reactor installed inside the land cruiser.


    First of all, naturally, it was just proposed to cut a hole from the bottom of the land cruiser to remove the core of the reactor.


    In addition, it can also open a door at the rear of the big guy, which is designed to lift shells and escape personnel. After opening, it is very close to the reactor, and can also be used as a passage to transport the reactor out.


    However, compared with cutting from the bottom, the workload of using this passage is greater. It needs to use a crane, not to mention cutting some structures inside the land cruiser to get through the passage to the reactor, which requires a lot of construction.


    As for the other passage, it''s not so troublesome. It doesn''t need to be cut. It''s also the way that the sovians used to install the reactor. As long as the turret of the land cruiser on the top is lifted by a crane, the whole reactor can be removed.


    This method is really simple, but the premise is that there is a large gantry crane that can lift the 305 mm twin turret.


    Although the military base has complete facilities, there is no such large gantry crane. What can be used is a small crane used to lift shells.


    So after some discussion, we chose to cut from the bottom to open the access from the outside to the reactor.


    Now that we are ready to dismantle the new reactor, we have no time to prepare for the dismantling of the new reactor.


    However, it''s freezing. It''s not easy to prepare the sarcophagus to be used for sealing the pile, so it''s not urgent. We have to take our time and do some preparatory work first.


    While controlling the nano armor to cut the interior of one of the Land Cruisers and prepare the passage for taking out the reactor, Chen Xin finally entered the interior of the prototype and saw the important target of his journey, the energy crystal.


    To be honest, Chen Xin was looking forward to this thing before he came here. In his opinion, it should be a high-energy object similar to the magic cube of the universe, or something that looks very cool or sci-fi.


    But when he finally saw the energy crystal, Chen Xin''s expression could be summed up in two words: this?


    The energy crystal embedded in this prototype by the suvians as an energy source looks dull and badly damaged, just like a burnt crystal left at the scene of the explosion.


    If it wasn''t for the dim orange light inside, Chen Xinzhen thought that the original energy crystal had been switched.With a last curiosity, Chen Xin carefully removed the thing from the shelf that fixed it, then packed it with the container he brought, took out the prototype machine, and took it outside, intending to use the instrument to analyze it.


    In fact, there is a more efficient way, that is to take a look at the system upgrade interface. So far, Chen Xin has not found anything that has not been identified in the system upgrade interface.


    And after he took the energy crystal out of the prototype, he did.


    "Dilapidated Dilithium crystal"


    "upgrade plan 1: repair the crystal structure, upgrade the survival: 120000"


    "upgrade plan 2: fill the crystal internal energy, upgrade the survival: 1100"


    Chen Xin looked at the so-called Dilithium crystal in his hand with some surprise, did not expect that such an insignificant piece of Dilithium crystal, actually need to be replaced It takes so many survivals to upgrade.


    This is the first time he has seen such a small thing that he needs six figure survival, which is far beyond Chen Xin''s expectation.


    And even with the help of the system, Chen Xin still didn''t understand what it was and what its role was.


    However, judging from the upgrade plan displayed by the system, this lithium-ion crystal seems to be broken, and it is not like the so-called energy crystal, because the survival required to fill the internal energy is too little, which is far too poor compared with the complete repair of the crystal.

 Chapter 478

    "So what on earth are you?" Chen Xin stares at the crystal in a transparent container and feels a headache.


    Although we know that this is not an energy crystal, new problems are put in front of Chen Xin.


    If it is not an energy crystal, what is it? Why does it keep releasing energy without any loss to its own shape?


    If this is a high-energy crystal, there is so much energy stored in it that it has dissipated. It is possible that there will be no effect for decades.


    After all, if you have the water from the Three Gorges Reservoir and connect it with a tap, even if you put it for decades, it may not have any impact on the whole reservoir.


    But the problem is that even if it''s a reservoir, it''s already a dry reservoir. Not to mention that Chen Xin has tried, this broken crystal is not a high-grade crystal.


    Although it does release energy all the time, after seeing this crystal, it gives people the feeling that the fire is about to burn out, and the heat in the remaining ashes has not completely dissipated.


    So it should not be an energy crystal, but something with other uses. It was just used as an energy crystal by the suvians.


    It''s just like in the past Nokia era, the main function of a Nokia mobile phone is to make phone calls, but it''s OK for you to smash walnuts with it.


    Obviously, the original suvians were the ones who smashed walnuts with their mobile phones.


    However, it is also possible that the suvians have not found the right way to use this kind of crystal at all, and there is no possibility of using it at all. They can only "recycle" it in the way they can think of.


    Thinking of this, Chen Xin has a headache.


    He couldn''t think of anything that the suvians couldn''t think of.


    After all, it''s an unknown new material. It''s impossible to guess what it is and what it''s used for from its name.


    "How did the suvians come up with this? It''s not like the Cold War era technology could make it. " Chen Xin hammered the table in front of him, looking a little incompetent and furious.


    On hearing Chen Xin''s complaint, the officer on one side thought for a moment and said, "it seems that this was not made by the suvians themselves. According to the information and documents we found in this base, this was found in the core area of the explosion after the Tungusic explosion by the expedition team sent by the Tsar at that time. It is said that a bracket and some metal were found together with this crystal Fragments.


    As for this piece of amber, which was lost to the Czarist in World War II, it was handed back to the suvia Institute for scientific research


    As the officer said this, he took out some information he had found in the base and handed it over to Mr. Chen.


    These materials look quite old. They are vacuumed and stored in bags one by one. Chen Xin can only look carefully to avoid damaging them.


    According to the records written in these materials and the matching ancient to ambiguous photos, Chen Xin thinks that if there is no problem with the contents recorded in these materials, then it is obvious that the truth of the Tungusic explosion, which has plagued mankind for nearly 100 years, has been very clear.


    It was an exploded spaceship or flying saucer, and the fragments of lithium crystal in front of us, as well as the metal fragments and supports found by the Czar''s expedition in those years, all came from the fragments of the exploded spaceship.


    Seeing these things, especially one of the photos taken by the expedition team when they discovered the crystal, Chen Xin had a new idea in his mind.


    He turned to the lithium crystal in the container, thinking about how to restore its original appearance and function.


    "Dilapidated lithium crystal crystal"


    "upgrade scheme 1: repair the crystal structure, add external parts, after upgrading, the catalytic core of the positive and negative material reaction furnace can be obtained, and the survival required for upgrading: 3200000"


    there is only one upgrade scheme emerging from the system upgrade interface this time, but there is no upgrade scheme 2.


    Chen Xin has now figured out what this is!


    If Chen Xin doesn''t understand what lithium crystal is used for, he can''t pretend to be a scientist. It''s more promising for him to go home and work honestly.


    It''s clear that among the countless brain holes about the cause of the Tunguska explosion, a few are right.


    It is obviously an alien spaceship that caused the Tungus explosion. After all, no one on the blue star knew what antimatter was. As for what caused the explosion of the spaceship, it is not known now. However, it is obvious that the great power of the Tungus explosion is largely due to the use of the antimatter reactor on the exploding spaceship.


    Positive and negative matter annihilation can completely convert matter into energy and release all the internal energy contained in matter. According to calculation, it even takes a few grams of positive and negative matter to react, which is enough to produce energy comparable to that of nuclear bomb explosion.So it''s easy to understand that there was a mushroom cloud in the Tunguska explosion, and the ship that exploded was almost dead.


    As for the reason why this crystal and its scaffold can survive, it is because it was originally installed in the positive and negative material reaction furnace. If it can not withstand the impact of the energy released by the positive and negative material reaction, it is not qualified to be used as the catalytic core.


    The reason why this thing has energy is also a good explanation. When this lithium crystal was placed in the positive and negative matter reaction furnace, it was always in contact with the positive and negative matter of the reaction, absorbed part of the energy released by the reaction, and converted into the internal energy of the crystal.


    This part of energy for the whole reactor may be only a tiny bit, but because of the high-energy environment in the reactor, the lithium crystal is full of energy.


    So after the explosion, maybe it''s because of the explosion, or the lithium-ion crystal itself will constantly release the internal energy, which has been slowly releasing energy outward for more than 100 years.


    It''s like a boiler after an explosion. Although the flame has been extinguished, its fragments still have residual temperature and need a period of time to cool down.


    It''s just that this piece of debris from the antimatter reactor contains a lot of "residual temperature". Even after more than 100 years of "heat dissipation", it still has a lot of energy left.

 Chapter 479

    Knowing what the crystal is, Chen Xin loses interest in it.


    Chen Xin is interested in the real energy crystal, but he has no idea to study it with the catalyst of positive and negative material reaction furnace.


    It is not only necessary to consume a lot of resources in order to really make the positive and negative material reaction furnace, but even if Chen Xinzhen made it, the positive and negative material reaction furnace is also very impractical.


    This is not to say that this technology is not good, but for the current Yan state, this technology belongs to the Dragon slaying technology, which can not be used at all.


    First of all, the positive and negative matter reaction furnace releases all the internal energy contained in the positive matter after complete annihilation through the reaction of positive matter and anti matter.


    The energy released by this way of releasing energy is amazing. Take coal as an example, the total heat energy released by a ton of standard coal in the conventional state is only equivalent to the energy released by 0.028 mg of material converted by mass.


    In other words, just a few grams of material into the positive and negative material reaction furnace, can produce hundreds of tons of coal to produce heat energy.


    A running reactor can produce more energy than a Three Gorges hydropower station.


    Such a huge amount of energy is too huge for Yan Kingdom and even the whole blue star to use.


    As for using only a few milligrams of material to react, it can only be called experiment, and it can not be regarded as a kind of energy.


    On the other hand, there is no stable and large-scale way to obtain antimatter for humans on the blue star. In the 100 billion dollar particle collider, physicists can often knock out some antimatter. However, due to their extremely rare number and easy annihilation, the cost of preparing one gram of antihydrogen atom is as high as 62.5 trillion US dollars.


    So even if Chen Xin got the antimatter reactor out, now Bluestar humans don''t have enough antimatter to burn.


    Now that Chen Xin has built a controllable nuclear fusion reactor, it is too early to study what kind of reactor is.


    However, Chen Xin thinks that it doesn''t matter that the country is interested in the crystal, and he doesn''t interfere. Anyway, the technology content of the crystal is very high. If the country wants to study it, it can study it carefully. Maybe it can produce some remarkable results?


    But Chen Xin himself is not interested in this thing. Now he just wants to get one of the three Land Cruisers back and transform it into a mobile base.


    This idea has been in his mind for a long time. He wanted to upgrade his RV to a mobile base like Rhode Island.


    However, although this idea has always existed, it has not been put into practice.


    On the one hand, Chen Xin doesn''t need to use the mobile base very much now, and it''s not practical to build one. On the other hand, it''s influenced by many other things, and he doesn''t have much time to study it.


    However, with a ready-made basic platform, Chen Xin thinks that he can still consider building a mobile base for himself.


    Anyway, the power sources of the three prototypes that can be safely used by the Land Cruisers have been removed, and the two nuclear powered prototypes can''t be used because of the nuclear leakage. It''s better for them to upgrade and get one that can be used to drive back.


    "Academician Chen, do you want to transform these Land Cruisers into mobile bases?" The officer was surprised by Chen Xin''s idea. Although he was also thinking about how to take these Land Cruisers back, he didn''t have Chen Xin''s exaggerated idea.


    He just wanted to put the lithium crystal back, use the spare parts found in the base to repair the prototype to the extent that it can be started, and then drive him back to Yanguo.


    However, this idea is obviously not as practical as Chen Xin''s idea of transforming it into a mobile base. After all, along the way, there are neither supply points nor navigation and guidance. It is not easy to cross thousands of kilometers from Siberia to Yanguo.


    With Chen''s new plan, it will be much easier to turn the land cruiser into a mobile base.


    "Yes, I had the idea of designing a mobile base that can travel on land, but I didn''t have a good idea for a moment. Now when I see the land cruiser designed by the suvians, I already know how to design what I want." Chen Xin explained to the officer and pointed to the Santai Land Cruiser standing on one side, saying: "one of them can be used as a transformation part. After being disassembled, it can be used to transform the other two. According to my idea, it should be possible to transform two mobile bases that can be used.


    At that time, we will be able to open these two mobile bases back to China and complete our tasks. Not to mention, these two mobile bases can be of great use in the current environment. For example, if we can open a mobile base to the disaster area in the southwest earthquake, it will play a great role. "When Chen Xin was talking about this, he was also thinking about whether he should get the mobile base out earlier.


    In fact, the functions of mobile base and air bag ark are similar, except that one is flying in the sky and the other is walking on the ground. Relatively speaking, air bag ark is more mobile, but on the contrary, although mobile base is less mobile, it can save in carrying capacity, versatility and other aspects.


    If Chen Xin can have a mobile base designed according to his idea during the earthquake, Chen Xin is sure to do better in the disaster relief process.


    As for Chen Xin''s idea of transforming the land cruiser into a mobile base, the officers did not stop him. After some consideration, they asked Chen Xin, "what about the nuclear radiation inside the two Land Cruisers? That''s enough radiation to kill people. It''s impossible to let people in, let alone take them apart and let the radiation leak out. "


    "How to deal with the radiation is my business. Anyway, what I can guarantee you is that after the transformation, we can get two mobile bases that can be used, and there is no nuclear radiation inside the mobile base." Chen Xin put his hands together to clean up the nuclear radiation in the two Land Cruisers with the strength of the system. However, it is difficult to explain to the officers exactly how to clean up.


    The officer also understood Chen Xin''s ability. He didn''t bother to ask Chen Xin to explain the process. He just said to Chen Xin, "academician Chen, you must pay attention to safety. Everything is based on safety."

 Chapter 480

    Mobile base is actually a very common setting. Large mobile vehicles or buildings appear in many games, movies and novels.


    Science fiction and magic are very common settings, and there are many derivative settings or related works.


    Take the land cruiser made by the suvians as an example. In fact, it is a kind of mobile base, but at the beginning, the suvians obviously used it as a combat vehicle in development, rather than as a mobile base.


    As for the difference, all the Land Cruisers developed as combat vehicles exist for the purpose of combat. Limited by the level of science and technology at that time and the design style of the suvians, they have narrow internal space and are basically used for combat cabins.


    In addition, there should be a place to accommodate the ammunition cabin and the transmission mechanism of the entire 305 mm dual mount battery. When driving this land cruiser, the soldiers can certainly play a strong combat capability, but they can''t think of any comfort.


    Chen Xin saw it in the prototype. Although this land cruiser does not involve the crew cabin, its space is basically just a narrow single bed on which soldiers can lie for a while.


    Moreover, these bunks are all designed with two or three bunks stacked together, which is narrower than the space between the upper and lower bunks in the sleeper compartment, and all bunks are basically near the combat position, which seems to be for the first time to enable soldiers to fight.


    As for the other functional cabins, they are all for fighting. In addition, a large number of sound insulation and shock absorption materials are laid inside the whole land cruiser to prevent the members inside from being directly killed when firing, so the space inside the whole land cruiser is even narrower.


    But mobile base is not the same, it has more complete functionality, can exist as a "base", provide logistics, materials and other aspects of security.


    And as a base, although it is not necessary to emphasize the comfort of living, there should be enough living space, even the kitchen and dining room.


    After all, it is a base. Although the mobile base is not necessarily as large as a regular fixed base, it should at least be able to cope with various scenes.


    According to Chen Xin''s design, the scale of the mobile base should be larger than that of the land cruiser, but there is no need to fill the interior so full. For example, the traditional structure that the suvians crammed in to install the 305mm dual turret and the buffer structure used to support the artillery attack can be completely removed.


    As for the sound insulation and shock absorption materials, they can be replaced with more modern materials, and the design structure can be optimized.


    In the final analysis, the mobile base still has to run on the road. For such a big thing, shock absorption and sound insulation also have to be done. Otherwise, it can overturn the table, but it can''t.


    "So the cannon is sure to be dismantled, and there is no need to use the original design for the nuclear reactor..." Chen Xin used nano molecules to project a three-dimensional image of the land cruiser, and is making adjustments bit by bit.


    The two prominent and powerful gun barrels were removed together with the whole turret, which not only released a lot of load, but also made a lot of space on the chassis.


    Although it is said that a gun should be installed as a self-defense weapon or a road sweeper, the caliber of 305mm is too large, so it is very inconvenient to use.


    Just as modern warships are only equipped with guns of less than 150 mm caliber and only one gun, the main means of attack has been replaced by better missiles. Even if Chen Xin wants to install weapons on the mobile base, he can only install a 130 mm naval gun at most. He will not use such a large caliber thing any more.


    The interior space of the whole land cruiser also needs to be redesigned.


    Although the original designers of suvia were very talented and could design such a big steel monster, suvia has been disintegrated for more than 30 years. Although many designs are exquisite today, many designs are outdated and need to be adjusted.


    Moreover, now that it is not for combat, many parts of it can be removed, and new functions also need to be added.


    According to Chen Xin''s idea, there must be restaurants and bathrooms, and the cabin should be more or less transformed into separate compartments instead of just a few single beds.


    In addition to these, Chen Xin also plans to add a hangar and apron to the mobile base.


    This is the result of referring to warships and mobile bases in many sci-fi works. If there are helicopters, mobile bases can quickly deploy action teams. If there is anything, you don''t need to drive the whole base to arouse the public.And with helicopters, all terrain vehicles and other vehicles naturally can not be less, so we have to add a garage.


    With Chen Xin''s idea, the stereoscopic images projected in front of his eyes are gradually changing.


    The gun barrel and turret disappeared, the body was elongated, and a pair of crawler chassis was added at the bottom, making it six from the original four tank chassis, with six pairs of 12 tracks.


    At the same time, the whole power system was replaced by Chen Xin. The original nuclear reactor really occupied the position, not to say, it was a very old-fashioned design. Now Chen Xin has simply replaced it with his own fusion furnace.


    Smaller size, more powerful output, enough to provide surging power and abundant power for this mobile base.


    In addition, a new garage is added at the rear of the chassis to fill the middle part of the original frame structure.


    Although this may reduce the traffic capacity of the car on uneven ground, considering that the track chassis on both sides is not particularly high, it is OK to add a garage.


    With the turret removed from the top, Chen Xin added a hangar and made a retractable apron on the side for helicopter take-off and landing.


    According to the size, four helicopters can take off and land at the same time, which is very enough.


    Naturally, all the cabins inside are redesigned to make them more reasonable and comfortable.


    Although the interior space of a mobile base is certainly not as spacious and comfortable as it is, it should be reasonably planned, with complete and modern functional facilities, so that the passengers will not feel depressed and depressed when they live in it.


    In addition to the kitchen, dining room, bathroom, toilet and other functional facilities, as well as auxiliary facilities such as water supply tank, the entire mobile base is adjusted.

 Chapter 481

    It was not the two nuclear powered Land Cruisers that were disassembled into parts for upgrading, but the prototype without nuclear radiation pollution.


    In fact, this is also inevitable. Although the system upgrade can deal with nuclear radiation, the system will not regard an integral thing as a part, and it must be disassembled.


    The dismantling of the two nuclear powered Land Cruisers will inevitably lead to a large amount of internal nuclear radiation leakage, so they cannot be dismantled.


    Since nuclear power cannot be disassembled, we can only disassemble the prototype, which has nothing to do with radiation.


    Although the 305mm twin turret, as the main part, can''t be removed without a large gantry crane, there are still small aerial cranes in this base, which can remove other parts.


    After dismantling, all that remained in the prototype was the internal main structure framework and the 305 mm dual loading turret that could not be removed.


    The rest of the parts are piled up on the ground in different categories and become parts of the ground.


    Although the accompanying staff were puzzled by Chen Xin''s dismantling of the available prototypes, they still carried out Chen Xin''s order.


    On the one hand, it is the suppression of Chen Xin''s identity level, which is an order that they should not carry out.


    On the other hand, they think that it is easy to understand the structural design of a land cruiser by dismantling one. After all, looking at the drawings and dismantling the real object are two completely different experiences.


    You can''t see why some designs are designed in this way on the drawings. Only after dismantling the real objects can you clearly understand why they are designed in this way.


    So we didn''t contradict. We directly disassembled the prototype of the land cruiser.


    After the dismantling, they now have a thorough understanding of the land cruiser.


    It has to be said that the design concept of this thing is very consistent with the idea of suvians that enough is enough. Many internal structural designs are designed with the idea of making one first, using it, and leather is durable.


    Although it does meet the needs of function and use, many places do make people feel very inhuman, and there is still room for improvement.


    Of course, this is from the perspective of the present.


    If we go back to the time when this thing was just designed, it would be a great thing to be able to build such a group of people with the technology of that time.


    As for whether it''s easy to use or not, for Yanguo, who also inherits maozi''s design concept, it''s better to solve the problem first, and then take a quick step. However, Yanguo''s consistent equipment design ideas and concepts don''t feel that the idea of suvians'' stupid big black rough solving the problem first is wrong.


    After the staff took photos of all the parts and kept records, Chen Xin used these parts as upgrade materials to upgrade the two Land Cruisers.


    As the green light in Chen Xin''s sight swept by, two Land Cruisers equipped with giant guns disappeared and replaced by two mobile bases that looked more square and solid.


    "This is..." the officer looked at the new mobile base and felt shocked.


    Chen Xin doesn''t care what kind of upgrade process he sees in other people''s eyes. Anyway, the system can help him solve the problem every time and give him a reasonable excuse. He doesn''t have to bother to explain it again.


    He can''t wait to get into the two mobile bases to see if the things he''s making are working well.


    The two mobile bases refer to the famous mule island in appearance. In front of the whole mobile base is a huge obstacle clearing device, which is used to clear the road and facilitate the driving of the mobile base.


    But different from Rhode Island, the whole mobile base is composed of six pairs of twelve tracks as the operating mechanism, like six tank chassis juxtaposed under the mobile base.


    As for the main support structure, Chen Xin still uses the (suvian) design, but adds a garage in the middle of the (suvian) support beam, which is equipped with an all terrain vehicle and several small all terrain vehicles.


    There are seven entrances to the mobile base, two entrances on each side of the car bottom, and two gaps between the three tracks, a total of four.


    The other two entrances are on the roof of the car, part of the hangar. The rear part is also an entrance, but that''s the garage door.


    Above the garage is the engine room. This floor not only has the nuclear fusion reactor as the power core, but also has the main power equipment such as generator and transmission mechanism, which is the core part of the whole mobile base.


    Even considering Chen Xin''s need to observe the road conditions while driving at the mobile base, he even put the cockpit on this floor.Above this level, there is the crew compartment.


    The passenger compartment is relatively simple. After all, the area is limited. Chen Xin doesn''t have it either. It''s very big here. Apart from the cabins arranged on both sides of the car body, there is a relatively large public space in the middle, which has multiple functions such as meeting room, living room and dining room.


    The bathroom and kitchen are set at the front and rear of the car respectively. The bathroom is public and close to the bathroom.


    Domestic water is provided by two huge cylindrical water tanks on the roof, and the domestic sewage generated will be recycled by the recycling system installed at the rear of the car for reuse.


    The parts that can not be recovered will be discharged after proper treatment.


    Along the crew cabin and on the Internet, there is the hangar and command center.


    Here, Chen Xin referred to the design of the aircraft carrier''s hangar and deck. The command center adopted a similar ship island design, which was located on the right side of the whole mobile base. The crew cabin and engine room were connected up and down, and elevators were installed to facilitate command transmission and personnel movement.


    The space of the hangar itself is not too large. It can accommodate up to six helicopters with folded blades. On the left side is a retractable apron, which can be used for four helicopters to take off and land at the same time.


    As for the part of the roof, it is also an apron. There is a similar lift on the aircraft carrier to lift the aircraft.


    The strength of the top apron is designed according to the strength standard of the aircraft carrier. It can be opened from the inside and the whole hangar can be expanded. Not to mention, in the case of closure, it can also allow fighters with vertical take-off and landing function to take off and land.


    In addition, Chen Xin has left a design margin in the overall structure of the whole mobile base. He can install a common vertical missile silo on warships in the whole mobile base near the front and rear of the vehicle, or abandon the use of the top vertical take-off and landing deck, cancel the opening and closing function, and directly deploy missiles.


    Of course, these design margins are reserved for military transformation. Chen Xin did not install these on the two mobile bases, but installed a 130mm gun in front of the command center ship island on the top for clearing obstacles.

 Chapter 482

    "With such a transformation, the internal space has really expanded a lot!" The officer and Chen Xin entered the interior of the mobile base together. Seeing that the interior space became much wider, they could not help sighing.


    "After deleting some unnecessary structures, the available margin of the internal space itself has increased a lot. Making the space more spacious is only the inevitable result of optimizing the structure." In the face of praise, Chen Xin just politely said another question: "these two mobile bases have now been transformed and can be taken back, but each one needs at least 15 people to drive. Do we have enough manpower?"


    To this question, the officer was very confident: "because when he came here, he thought about bringing back three Land Cruisers. We have 20 members for each land cruiser. All of them are tank groups drawn from the armored forces, and they can drive this thing back."


    If it was a land cruiser before, the officers didn''t think much about whether they could take it back. But now Chen Xin has transformed it into a mobile base, which has a completely different meaning. Naturally, they need to drive these two new mobile bases back.


    While they were visiting the mobile base, the officer also asked Chen Xin some questions about the mobile base.


    "Academician Chen, what is the main function of this mobile base? Where can it be used? " This is the major concern of officers. After all, such a big thing can''t be used as a transport vehicle.


    "At present, these two vehicles belong to white board vehicles, that is, prototypes. They do not have professional functions. At present, they mainly have limited functions, such as helicopter take-off and landing maintenance, rapid land and air deployment of operation teams, logistics support, combat command and firepower support." Chen Xin and his officers came to the public space of the crew cabin. As they opened a chair and sat down, Chen Xin projected a three-dimensional image of the mobile base on the table, so that the officers could see more directly.


    In the projection, Chen Xin simulated the rapid deployment of all terrain transport vehicles as operation teams under the escort of all terrain vehicles, as well as the landing and take-off process of helicopters and VTOL fighters.


    Seeing this, the officer nodded clearly. These are very practical functions. For a mobile base vehicle, these functions are worth the ticket price.


    In fact, the mobile base is very similar to the amphibious attack ship equipped by the Navy, but it is too small, and its tonnage and length are much different.


    But from the functional point of view, the two are very similar, with rapid support and deployment capabilities.


    However, compared with the Navy''s warships, which often weigh tens of thousands of tons, the mobile base is much lighter and more flexible, and easier to deploy and use.


    In the view of officers, this large land vehicle is not used as a transport vehicle, but carries an action team and is deployed rapidly by helicopter.


    The civil type can completely transform the hangar and crew cabin into a hospital, and realize regional rapid rescue by carrying helicopters and ambulances, which is very useful for earthquake relief.


    The military type can carry armed helicopters and combat teams to become a regional combat support platform. At the same time, it can also be used as a mobile action center to provide firepower and logistics support for regional operations after strengthening firepower.


    On the battlefield, such an operation center can rapidly deploy special forces and armed helicopters at any time, but it is very able to ensure the regional control.


    Chen Xin did not forget to introduce to the officers the fact that the mobile base can carry missiles, which made the officers feel that the mobile base is a very fragrant equipment for the military.


    Of course, the mobility of the mobile base and the difficulty of deployment make it a little less practical.


    After all, after Chen Xin''s renovation, although it is supported by six tank chassis and 12 tracks, it can keep its moving speed and not crush the road, but it can''t cover up the fact that it weighs more than 200 tons under no-load condition.


    According to Chen Xin''s estimation, the total weight of the mobile base can reach more than 300 tons when it is fully loaded, not counting vehicles.


    If the helicopter and all terrain transport vehicle, as well as the spare parts, fuel and ammunition prepared for them are included, the total weight can even exceed 400 tons, approaching 500 tons.


    This is a very exaggerated weight for the army. If it wasn''t for the suvians, when they first designed the land cruiser, they used it as a chassis for artillery, especially to strengthen the load-bearing capacity and supporting structure. When Chen Xin upgraded, he specially strengthened and improved the load-bearing system. The weight of 300 to 500 tons was enough to crush any road.


    However, even so, such a heavy mobile base can only drive on relatively solid ground. In today''s extremely cold environment, although the snow is strong enough to withstand this thing, it is not easy to say that it can''t bear it, but it can''t run around casually.Therefore, how to use the mobile base and how to transport and deploy it to the required area is a key problem.


    However, in general, the mobile base itself does not belong to the type of equipment for rapid deployment. It can be transported in the form of parts to the area to be deployed for assembly, or it can be produced and then driven to the destination by itself.


    Although the speed of the latter is really urgent, the rapid support capability of this mobile base is still considerable if it is deployed by region.


    "According to my imagination, this kind of thing can be used as a disaster relief command center. Although it overlaps and is similar to the airbag ark in function, and it can be deployed quickly without the airbag ark, it also has the advantages that the airbag ark does not have." Chen Xin seems to be interested in discussing the use of the mobile base with the military officers: "if the mobile base is transformed into a mobile hospital, as long as it can be deployed to the disaster area, the rescue and treatment can be carried out quickly to save more people."


    "That said, but the moving speed of this mobile base..." the officer said with a wry smile and tilted his head: "after all, it''s hundreds of tons. It''s too slow to drive to the disaster area by itself."


    "This is really a problem..." Chen Xin also nodded his head in affirmation, but he said: "according to my design, this mobile base can theoretically move at a speed of 30kmh under normal conditions, and 50kmh under full load limit state. As a mobile base, this speed is enough, and it is nuclear powered, There''s no need to think about parking at all.


    As for the issue of rapid deployment... Have we got the information on the MI-12 helicopters of the suvians? "


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 483

    How to quickly deploy the mobile base is not an issue Chen Xin needs to consider.


    He and the officers only discussed the possibility of using heavy helicopters such as MI-12 to lift the mobile base from the sky. After all, MI-12 helicopters have the amazing performance of lifting 40 tons in history. If there are five or six MI-12 helicopters, it is not a problem to lift the whole mobile base.


    It''s just like the movie in which a helicopter is used to lift a pretty boy from skull island. There are more than a dozen Mi-26 heavy helicopters to lift a mobile base for rapid deployment. It''s really not a problem.


    It''s really no good. Chen Xin thinks it''s a big deal to upgrade a few heavy helicopters with enough takeoff weight for the mobile base, which can also solve the problem.


    Skip the problem of how to deploy. Everyone in the mobile base thinks it''s a very practical thing.


    Although the mobility is not strong, it is very satisfactory to be able to provide good logistical support and regional support capabilities.


    After Chen Xin upgraded the original three Land Cruisers to mobile bases, Chen Xin and his party''s mission to Lucia was successfully completed. The next thing they had to do was to return home with two mobile bases and two lithium crystals.


    However, the return journey is somewhat troublesome. When they come, they take the train. Naturally, they return by the same way. However, it is obviously impossible for the two mobile bases to follow the train.


    "Let the two mobile bases go south by themselves. The mobile base itself has enough ability to cross Siberia and return to China. We leave enough materials for the two vehicles, which can be regarded as a test on the way." Chen Xin thought about it for a while, so he suggested.


    Of course, Chen Xin has enough confidence in the two mobile bases. It would be a shame if he could not even make the nuclear powered mobile base that he had painstakingly built.


    Of course, as far as the mobile base itself is concerned, it can indeed drive back to China from Siberia. The only worry is whether the members of the car can drive it back.


    After all, apart from material support, there is no navigation and map along the way. Along the way, there is no man''s land in the real sense of Siberia. It is not easy to drive back to China.


    "I agree that if we let the mobile base follow the train, we have to make a detour to Kazakh, where we can''t get supplies. The train doesn''t matter. It doesn''t take much time to come, and it can be faster to go back. But these mobile bases can''t keep up with the speed of the train. Instead of making them follow us around, we''d better let them go straight back." The officers also felt that it was inappropriate for the two mobile bases to follow the train.


    Chen Xinjian, an officer, agreed to do the same, so he nodded and added: "besides, a trip like this can also test the long-distance mobility of the mobile base, so as to have a comprehensive understanding of the performance of the mobile base.


    But it''s still dangerous to do so. In case the mobile base breaks down on the road, or they run the wrong way, the problem is very serious. "


    "I believe that our soldiers are all elite tank units drawn from the armored forces. Even without electronic navigation, they will not run the wrong way." Officers have full confidence in the soldiers they bring. After all, this is one of the basic skills of tank drivers: "as for whether the mobile base will be damaged on the road, isn''t it necessary to run a test? How do you know if it''s going to break without running


    Hearing what the officer said, Chen Xin didn''t think about it any more. After thinking about it, he said, "that''s it! There are two routes. The train goes back along the original route. The two mobile bases go south by themselves. I go back with the mobile base. Even if there are any problems on the way, I can repair them in time to ensure that they can drive home. "


    "Ah? This... "The officer heard Chen Xin say so, immediately want to stop, after all, Chen Xin is more important than the two mobile bases and soldiers.


    But Chen Xin held out his hand to stop him and continued: "as you can see, there is no problem with the safety of these two mobile bases. The only possible problem is that the mobile base breaks down or is damaged in the middle of the way, and we run out of supplies and starve to death on the road.


    But with me, even if it''s broken, I can repair it in time, and there won''t be such a problem. So I''ll go back to the mobile base, and there''s no security problem. "


    Mobile base is not a car or other vehicle. In terms of safety, it is much safer than the train they come from. The only problem is that there are no materials on it.


    After careful consideration, the officer agreed to Chen Xin''s idea of returning home with the two mobile bases.


    But he still insists on following Chen Xin and asking for personal protection.


    To this, Chen Xin also has no way to refuse, had to agree naturally come down.At the end of their discussion, when they made a return plan, they unexpectedly received a communication from Lucia.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "What''s going on? We are thousands of kilometers away from the nearest city. How did they contact us? " The officers were a little surprised. Although it is true that ultra long wave and long wave radio can communicate over thousands of kilometers, they are not carrying such ultra long distance communication equipment. It is not a simple thing to contact them.


    "It''s the pig. They''re on their way back. We''re in their communications coverage." The radio operator reported the situation to the officer: "only they said that there was an accident in Lucia. They returned home to ask for help."


    Hearing this, both Chen Xin and the officers changed their faces and asked in surprise, "what''s the matter with Lucia? Didn''t pigs and dogs go to support them before? Why do you need help? "


    "Haizhu said that a large-scale epidemic broke out in the capital of Lucia. Medical experts in Lucia said that it was an ancient virus released by the melting of Arctic glaciers before. The immune system of modern people can''t resist the attack of this virus. Now the epidemic is spreading in several major cities in Lucia and their capital, and the situation is very serious." The correspondent gave the information he had recorded from the Hai pig to officer Chen Xinhe: "someone on the Xu dog was infected with the disease. Now he is staying in the capital of Lucia to help rescue and prevent the spread of the disease. But there is no one on the Hai pig, so he went back to seek help."


    At this point, the correspondent stopped for a moment, took a look at Chen Xin and the officer''s face, and then continued: "Hai Zhu, I hope we can also help them."

 Chapter 484

    "Ask us for help. What can we do for you?" The officer could not help feeling that he had a big head. He couldn''t help this kind of thing: "we didn''t carry rescue supplies or enough medical supplies. We only had our own spare medicine. Even if we wanted to help, we couldn''t help it!"


    Chen Xin also nodded, frowned and said: "we are thousands of kilometers away from the capital of Lucia. It''s not easy to cross the vast wilderness of Siberia for more than 1000 kilometers, not to mention whether we can help."


    But at the same time, Chen Xin also looked at the correspondent and asked him, "how far is the Hai pig from us?"


    "Haizhu is currently on the return route to China, about 800 kilometers away from us." When communicating with the Hai pig, the correspondents recorded their location information through radio positioning.


    The technology of positioning by radio echo was originally used in ship navigation, and also in aircraft.


    After the airbag ark was manufactured, in order to give them positioning and navigation, it was also equipped with this set of equipment, which can locate the position of itself and each other through radio signals.


    It is precisely because of such equipment that Haizhu can find their location and get in touch with them when they turn on the radio.


    "Ask about the details of the Hai pig, Xu dog and the capital of Lucia, especially the spread of the epidemic. Even if we want to help, we have to know the situation first." Chen Xin told the correspondent to let him get in touch with the Hai pig again. At the same time, he also said to the officer, "take the map, let''s calculate how long it will take to get to the capital of Lucia from here."


    "Academician Chen, we can''t help lucians. You don''t want to go to their capital, do you?" When the officer heard Chen Xin say so, he wanted to stop him.


    However, Chen Xin shook his head and motioned to him to find the map first: "you go and get the map first. As for whether you want to go to Lucia''s capital or not, whether you want to go or not, we must be ready to go to rescue and return home."


    "OK, I see." Seeing Chen Xin say so, the officer took out the map of Lucia found in the base.


    Looking at the map, Chen Xin frowned. The military base they are now in is Siberia, which is the Asian part of Lucia, while the capital of Lucia they are going to is in its European part. The straight-line distance between them has exceeded 4000 km.


    "Too far away!" Looking at the distance measured on the map, Chen Xin really felt that they did not have the ability to participate in the rescue.


    It''s a straight-line distance of more than 4000 kilometers. Even if they can go to Novosibirsk, the central city of Lucia, from where they are now, and then go along the road to the capital of Lucia, there are almost 3200 kilometers of straight-line roads on the map.


    "Even if we go there by train, it will take us about a week on the way. This is still under the condition that the railway can keep open at present." Looking at the map, the officer frowned seriously: "according to academician Chen, the moving speed of the mobile base is about 30-40 kilometers in an hour. Even if we don''t consider other situations, it will take almost two periods to go to the capital of Lucia in a straight line.


    If there is any accident or breakdown on the road, it will take us at least one month to reach the capital of Lucia. Instead of taking such a long time to get there, we''d better go back to our country and try to find a way to get to the capital of Lucia from home, which will save some time. "


    The officer deliberately mentioned returning to China first. No matter how he wants to come, it''s serious to send Chen Xin back to China first.


    For a scientific researcher like Chen Xin, the first thing an officer should do is to ensure his safety. Now that he knows that the epidemic has spread in Lucia''s capital, he can''t be allowed to go to the epidemic area.


    As for whether Chen Xin will go to Lucia''s capital after he returns to China, that is another case.


    The officers believed that the state could not let Chen Xin go out of the house without proper preparations.


    Chen Xin naturally thought of this, but he didn''t have to participate in the rescue. After thinking about it, he said: "it seems that we can''t help. Even if we can get there, it will take at least half a month. For such a long time, it''s much faster for us to go back home first, and then take a plane or an air bag ark from home, and then go to the capital of Lucia."


    "Yes, even if we want to help, we have to go back to China first and replenish our supplies." The officer followed Chen Xin''s words and pointed out an objective fact: "we don''t have any medical supplies or relief materials here. Even if we get there, there are few places we can help. Moreover, our supplies are not enough, just enough for us to return home. ""Are we short of supplies?" Chen Xin looked at the officer in surprise and was surprised by what he said.


    "Originally, we had enough supplies, but they were calculated on the basis that we went back and forth by train. Although the time has come for us to prepare a plan to take the land cruiser back, and more supplies have been prepared, on the whole, our supplies are not enough. After the supplies left for the two mobile bases are separated, our supplies are only enough for us to return. " The officer explained the situation to Chen Xin.


    In fact, the materials they are carrying are not so tense that they need to be counted. After all, if the material card is so dead along the way, it will be finished in case of an accident.


    However, the officer played a careful eye here. He deliberately made the situation of materials a little nervous, telling Chen Xin that they had no spare materials to go to Lucia''s capital, so that he could give up the idea and return home quickly.


    After hearing what the officer said, Chen Xin thought about it seriously and gave up the idea of rescuing the capital of Lucia.


    "It seems that we have to go back to China first. As for the others, we''ll wait for the Hai pig to send us the details." Chen Xin finally gave up the idea of responding to the Hai pig''s request for help.


    Although for Chen Xin, he can take advantage of the several suvian helicopters found in the base, upgrade them and drive to Novosibirsk, which is not far from the base, and then go to the capital of Lucia from there.


    But it''s just Lucia, not the motherland. Chen Xin doesn''t need to spend so much effort on another country.

 Chapter 485

    Now that he has decided to go back and ignore Lucia''s affairs, Chen Xin and his officers will naturally pack up and prepare to go back.


    Although all kinds of instruments and equipment brought with them are hardly useful, they are still moved to the base. Now these things have to be packed and put back into the car.


    As for all kinds of information they found in this military base, they were naturally handled by special personnel and brought back.


    Some of the other valuable items found in the sealed military base were loaded on trains, while the rest were put on two mobile bases.


    Although Chen Xin did not design a large load and storage capacity for the mobile base when he designed it, he could still hold a lot of things.


    After all, the garage at the bottom and the hangar at the top are still empty. If necessary, these two places can be used as warehouses temporarily.


    As a matter of fact, the garages and hangars of the two mobile bases are now stacked with some well-developed military equipment and several aircraft from the military base.


    Although these things are old things decades ago, the design of some of the equipment still has considerable reference value even today. Since they can be taken away, naturally they will not be taken away for nothing, and they can also be taken back as a reference for the designers of Yanguo who have inherited the equipment design route of suvia.


    You should know that although the state of Yan got a lot of equipment and relevant information from suvia, many of these information were incomplete, or a whole series of steps from one to ten were missing.


    There may be only two, four and six in Yan state. If we want to make up for the missing one, three and five, and then go to ten by ourselves, the scientific research workers in Yan state have made great efforts and painstaking efforts that ordinary people can''t imagine.


    In the process of one to ten, there may be only seven or even five left here, but this can make up for the missing link of Yan state.


    What''s more, it used to be a secret military base for testing experimental equipment in suvia. Many of the works that can be sent here are full of creativity of designers in suvia.


    Although many of them didn''t have the value of mass production and equipping the whole army in the eyes of the leaders of suvia at that time, these things still represent the most cutting-edge achievements of the red giant bear in military science and technology in the Cold War era, which was one of the two poles of the world and once oppressed the whole world.


    Even more than 30 years have passed, some of the equipment still has a cross era significance, with extraordinary creativity.


    Although these things may have no great effect, they can provide more ideas and references for the current equipment research and development.


    After loading everything on the mobile base and train, the supplies brought by them have been redistributed, and the two mobile bases have been equipped with drivers. Chen Xin left the dusty old suvia military base and set foot on the road of return.


    As for the military base, it will still be closed again and remain here.


    Maybe a few years later, when the ice and snow melt and someone comes here again, they will dig it out again and tell people that there was a country called suvia in the past.


    Feeling the vibration from his feet, Chen Xin stood in the command room of a mobile base and looked through the window at the huge searchlight in front of the mobile base, illuminating the road ahead. Chen Xin asked the conductor who was in charge of the command: "how fast are we going now?"


    "Report, our forward speed is 21kmh now." The conductor quickly inquired about the cab of the engine room and reported the situation to Chen Xin.


    Chen Xin nodded slightly. Although the speed did not reach his expected 30-40kmh, it was not unacceptable considering the road conditions and their full load.


    "Keep that pace and move on." Chen Xin said, then nodded to the conductor and left the command center.


    The driver is mainly in charge of the cabin of the engine room, and the command center is responsible for the command of the whole mobile base. Although it sounds strange, the command center is not directly responsible for driving the mobile base.


    Leaving the command center, Chen Xin did not go to the crew cabin to rest, but went down to the engine room and came to the cab.


    Compared with the command center, the vibration of this floor is obviously larger, which makes Chen Xin pay attention to it and remind himself that after that, he should strengthen the damping of the mobile base.


    However, Chen Xin felt it carefully. In addition to the vibration caused by the contact between the track at the bottom and the ground, the vibration came from the operation of various equipment in the engine room.


    In fact, this is the same as ships and warships. The engine room is always the noisiest place on a ship and the worst place in the environment.But at the same time, it is also the most important place on the ship. If the engine room breaks down, the ship can''t go.


    And for this mobile base, the engine room is just as important.


    There are several soldiers in charge of maintenance. They used to be the drivers of tanks. Compared with tanks and combat vehicles, the space of the mobile base is much more spacious, and the vibration is not so exaggerated.


    Therefore, although the noise and vibration in the engine room are not small, the environment here is actually pretty good for those tank soldiers who are used to talking in tanks and need to use talkers, and the vibration can make people shake left and right to hit their heads.


    Chen Xin and a few soldiers said hello, this just walked into the cab.


    Like the command center, the cab can see the outside, but it is different from what the command center can see. From the cab, all you can see is that the huge obstacle sweeper in front smashes and clears all the obstacles in the direction of the mobile base.


    A large part of this huge obstacle sweeper comes from the original land cruiser, but the original design adopted by the suvians was a huge toothed roller, and Chen Xin improved it into a combination similar to comb and shovel.


    This huge obstacle remover will level the uneven road properly, and obstacles such as stones or trees will be pushed away or destroyed.


    As a result, when you look out of the cab, all you can see is the obstacle sweeper, which is huge enough to block the front of the mobile base, and the snowflakes and sawdust flying around under the obstacle sweeper.


    Siberian forest trees are very high, even if there is snow cover, there are still a considerable number of trees exposed to the ground, so if you want to drive past, you must cut down these trees exposed to the snow.


    When using the obstacle remover, it is directly crushed.

    Because the nuclear reactor is used as the power source, the mobile base does not need to stop and refuel like conventional vehicles, and the crew compartment inside the mobile base ensures that the mobile base can continue to move forward even at night, and the rest of personnel will not affect the operation of the mobile base.


    However, although it was night, Chen Xin still did not rest.


    On the one hand, the vibration and noise from the car body made him unable to sleep. On the other hand, he was still thinking about Lucia''s discovery of the ancient virus.


    The existence of ancient viruses has long been confirmed by scientists.


    These ancient viruses, which have been buried in the earth for tens of thousands of years, are quite different from all kinds of modern viruses that human beings are facing now. The key point is that all kinds of conventional antibiotics used by human beings have no effect on ancient viruses.


    Maybe some people think that modern viruses are more powerful than ancient viruses. The viruses that human beings are facing now are all evolved through the baptism of antibiotics. Modern viruses have nothing to do with human beings. What can ancient viruses do?


    Moreover, the virus is adaptive, and it evolves according to the host. It does not match with human. How can it infect human?


    Worrying about the ancient virus is nothing more than a groundless worry.


    However, these views are totally wrong.


    Nowadays, human beings are not afraid of viruses because we have built a complete defense system with antibiotics and modern medicine, which blocks the harm of viruses to human beings from the human body.


    In fact, without the protection of modern medical system and the immune system composed of a large number of antibiotics and vaccines, human beings are just weak and pitiful in the face of all kinds of viruses in nature.


    Before the disaster, COVID-19 had made human beings most incisive in the performance of the virus. Without modern medical system protection, vulnerable humans could hardly fight highly lethal and spreading viruses, and only bet on the 1/10000 probability of group immunity.


    However, even with the protection of modern medical system, it is still very difficult for us to win in the fight against unknown viruses.


    The war between human and virus is just a race against death.


    The mutation ability of virus is its most powerful weapon. Although modern medical science and technology are changing with each passing day, the mutation of virus has never stopped.


    Humans can develop a vaccine against a certain virus, but there will always be new viruses. In this war between humans and viruses, humans are on the defensive and can only defend passively.


    And the ancient virus is a new enemy that mankind has never faced.


    Fortunately, the extreme cold environment at the end of the day limits the spread of the virus. In addition, the long distance between Yanguo and Lucia physically blocks the way for the virus to enter Yanguo. This makes Yanguo not have to worry about the problem of ancient viruses for the time being, so that Yanguo can have enough time to deal with it calmly.


    But this is only temporary. Before the meteorite fall caused global fires, the Arctic and Antarctic glaciers, the Qinghai Tibet Plateau, the Siberian Plateau and other places have been affected. Those ancient viruses buried under ice and snow for thousands of years have been released. It is only a matter of time before their harm and impact will break out.


    At present, there is no epidemic situation in China, but it does not mean that there is no worry.


    So what Chen Xin is thinking now is how to prevent possible epidemics.


    It is not difficult to prevent the invasion of virus. At the beginning of the construction, the government shelters have considered filtering harmful substances in the air. In the case of no accident, the virus can not enter the shelters through air transmission.


    And human infection, as long as we can strictly implement the health regulations, do strict prevention, or can resist infection.


    But passive defense can''t solve the problem. With shield, there must be a spear to attack!


    Chen Xin is not a medical scientist or an expert in virus research, but he knows one thing, that is, the most effective way to fight the virus is vaccine!


    Vaccine is an automatic immune preparation for preventing infectious diseases, which is made of pathogenic microorganisms (such as bacteria, Rickettsia, virus, etc.) and their metabolites through artificial attenuation, inactivation or transgenic methods.


    The vaccine retains the characteristics of the pathogen stimulating the immune system. When the animal comes into contact with the harmless pathogen, the immune system will produce certain protective substances, such as immune hormones, active physiological substances, special antibodies and so on.


    Therefore, when animals come into contact with the pathogen again, the immune system of animals will follow its original memory and produce more protective substances to prevent the damage of the pathogen.In order to make a vaccine, the original strain of the virus is essential, and then it has to go through the multi-channel process of attenuation, filtration, animal experiments, human experiments and so on.


    According to the normal process of vaccine development, it usually takes more than three to five years, long or even more than ten years for a vaccine to be put into clinical use.


    So how to quickly and effectively develop vaccines and shorten the development cycle of vaccines is a very important thing in the process of anti-virus.


    Under normal circumstances, even if there is a large amount of investment, it is also a matter that can not get up quickly. After all, there should be no less programs.


    However, for Chen Xin, with the support of the system, we can consider manufacturing a kind of equipment that can quickly produce vaccines, and achieve rapid mass production.


    This is not very difficult for Chen Xin.


    In addition, because of this, Chen Xin turned his attention to medical treatment.


    Maybe it''s time to make some good medical equipment?


    Chen Xin thinks this can be put on the agenda.


    I took out a small notebook that I had always carried with me. It was full of various ideas and plans. Some of the things written on it have been realized, some have changed, and some have not been realized.


    With the development of medical equipment and vaccine preparation equipment for viruses written in the book, Chen Xin is also thinking about what kind of medical equipment he wants to make.


    Manufacturing medical equipment itself is not a difficult task for Chen Xin. Even the medical cabin that can automatically perform surgery and repair human trauma, and the nano robot that can enter the body to kill cancer cells


    For Chen Xin, these things are not very difficult to make, but he thinks that compared with all kinds of medical equipment for treatment, A light and compact, and can achieve rapid and accurate detection of the detection instrument is the most should be done out of the things.


    After all, most of the time, the difficulty is not how to treat, but how to detect and diagnose in time.


    As for what kind of testing instruments should be made, Chen Xin thinks that the three recorders commonly used by Lao Gu in Star Trek are a good choice.

 Chapter 487

    Because the whole route of the operation is wasteland, and the two mobile planes do not need to consider the issue of supply, they almost cross Siberia in a straight line, and are gradually approaching the country of Yan.


    "Where are we now?" In the command center, Chen Xin looked out of the window and asked the conductor.


    After a few days of adaptation and adjustment, now the entire fleet has gradually become familiar with and mastered the operation and driving of the mobile base. Compared with before, the mobile speed has been slightly improved, reaching the original design standard of Chen Xin.


    The conductor who was studying the route heard Chen Xin''s inquiry, looked at the map and replied, "we have entered uliyasutai now, about 1000 kilometers away from the border line. We should be able to enter Mongolia Province in two days."


    "Uriyasutai? I''m here. " Listening to the captain''s reply, Chen Xin opened the holographic map on the console in the control center, projected the map around the mobile base at this time, with a slightly emotional expression: "if suvia didn''t split it then, we would be back home now."


    For Chen Xin''s feelings, the conductor also has some empathy: "it''s really hard to say a word between Yan and suvia!"


    "Who said no? The old suvia For the response of the conductor, Chen Xin also gave a slightly complicated smile, with some emotion in his heart.


    It can be said that the relationship between suvia and Yan state is very complicated and has a very deep historical origin.


    At the beginning of the founding of the Republic of Yan, suvia was the first country in the world to recognize the existence of the Republic of Yan. At that time, suvia also gave a lot of help to the New Republic of Yan, so that for a long time, suvia was called big brother by the Republic of Yan.


    But later, the relationship between the two countries deteriorated, not only severing exchanges for decades, but also breaking out the fierce border conflict. The suvians used their troops to launch an attack on the country. The two sides fought fiercely for more than ten days, resulting in a total of 100 deaths and injuries.


    Although the relationship between the two countries has gradually returned to normal since the collapse of suvia, people who know the history of the two countries always have complex feelings when they mention suvia.


    Especially now they are stepping on the territory of Yan state since ancient times. However, in modern times, this land split from Yan state under the control of suvia and became a so-called country.


    "What''s the situation in uriyasutai? Their survivors should be more difficult than at home, right Chen Xin asked the conductor curiously, but didn''t expect him to answer.


    "The difficulties are certain. This country has been in a bad situation since it split up. Especially after the collapse of suvia, the external support was cut off and the people were in dire straits." The conductor seemed to know something about it and was very moved.


    Chen Xin knows something about this country. When Feng Yanran''s inscription was discovered in uliyasutai, a friend of his came to this country specially to see the great achievements left by his ancestors.


    This trip also gives Chen Xin''s friends the most intuitive understanding of uliyasutai.


    As the world''s second largest inland country, with the world''s 19th largest land area and rich underground mineral resources, the country is still poor, and its total economic volume is no match for a second - and third tier city in Yanguo, which can be said to be the poorest and backward country in Asia.


    More than half of their country''s population of more than three million people are crowded in their capital, resulting in almost most parts of the country being no man''s land.


    In order to maintain the operation of the capital, almost all the resources of the country are piled up in their capital.


    It is still a developing city in the last century. The pollution is quite serious. It is the most serious air pollution city in the world, and there is a huge gap between the rich and the poor.


    Such a country, it is difficult to believe that they have the ability to resist the doomsday disaster.


    Thinking of this, Chen Xin couldn''t help asking the conductor, "will we pass their capital?"


    "According to the way forward, we will not enter their capital, but academician Chen, if you want to have a look, we can also turn around." The conductor doesn''t mind. Most of the land in uriyasutai is Gobi and plain. Turning a little doesn''t affect the journey.


    However, Chen Xin shook his head and was not interested in it: "forget it, there''s no need to delay the trip in order to satisfy his curiosity. Let''s go straight home. They should have no hope."


    Chen Xin just made a little calculation in his mind and gave up the idea of taking a look.


    There are more than three million people in this country, and the industrial strength is almost zero. Half of the population of the country is concentrated in the capital. Although it is not impossible to build one or two shelters for high-rise buildings, it is doubtful how many people will survive.More than 3 million people can now have 1% left, and Chen Xin thinks that these people are in great danger.


    The conductor doesn''t think so either. Since Chen Xin is not interested, he won''t be fussy.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    When Chen Xin and Chen Xin entered uliyasutai, the Hai pig had already returned to China and reported to the high-level officials about the ancient virus infection in Lucia, which caused the epidemic to spread on a large scale.


    This has aroused the high attention of the senior management.


    Haizhu was completely isolated and killed. Although the members of the ship were not infected, no one dared to bet that the whole ark was not infected with the virus.


    As for whether to assist Lucia, the senior management has not made a decision, which is different from the previous material assistance. It''s a handy help and a good exchange.


    However, in the case of a large-scale spread of the epidemic in Lucia, the significance of helping Lucia is completely different, and the cost to Yan country is also completely different.


    In the case of a large-scale earthquake in Southwest China, the whole country is now in a situation of shortage of materials and medical resources. At this time, there is not much spare power to help Lucia.


    After all, the people of our country can''t be saved. How can we spare the strength to save the people of other countries.


    After all, the two countries have just reached an agreement on cooperation, and they have just come back with a pile of good things from Lucia. It''s not in line with Yanguo''s consistent style to leave them alone.


    What''s more, there is a dog ark trapped in Lucia. Before giving up rescuing Lucia, we have to get our family and ark back.


    Moreover, the emergence of the ancient virus also sounded the alarm for the country of Yan. Even if the outbreak of the disease in Lucia could not spread to the country of Yan, this situation is still worthy of vigilance and preparation.


    The virus on Lucia''s side may have been leaked from the Arctic and Siberia. There is also the Qinghai Tibet Plateau in Yanguo. But ancient viruses have also been found in that land. This kind of thing has to be prevented.

 Chapter 488

    Chen Xin''s speed of returning to China is not slow. Although the mobile base can only walk about 30 kilometers per hour, it can travel about 700 kilometers a day without stopping.


    Even though they set out thousands of kilometers away from Yanguo, after walking on the road for more than a week, the two mobile bases were able to smoothly enter the territory of Yanguo. After entering from Mongolia Province, they continued to go south.


    Because it has entered the country, communication has naturally been restored, and the senior management has also made contact with Chen Xin for the first time.


    After a brief exchange, Chen Xin also understood the current situation.


    Although the train that sent Chen Xin to Siberia went further, it was much faster, so they returned home much earlier than Chen Xin. Now they have arrived at their destination.


    In addition, Haizhu also returned to China, informed the high level of the situation, and is currently under isolation and observation.


    The other, infected by some of its crew, remained in the capital of Lucia, where the epidemic had already broken out, in order not to bring the virus back home.


    The top management is currently discussing whether to provide support to Lucia.


    As for the earthquake in Southwest China, at present, the aftershocks have subsided, and the post disaster reconstruction work is also in orderly progress.


    Although the whole southwest region was seriously affected by the disaster, a large number of casualties and material losses once made the southwest region fall into a very difficult stage, but with the deployment and full support of the high-level, the situation has improved.


    The worst hit City Chen Xin was in was rebuilt the fastest with Titan''s help.


    Although the reconstruction speed of other disaster stricken cities is not so fast, the reconstruction work has been carried out in an orderly manner, and the situation in the disaster area is also improving step by step.


    This reassures Chen Xin a lot. He just lets go of his worries about the disaster area. At the same time, he is also concerned about what decisions the senior management will make about Lucia.


    To this point, the high level did not give a reply, just let Chen Xin return as soon as possible.


    As for the two mobile bases, the senior management also did not give clear instructions, just let the two mobile bases send Chen Xin back first.


    In the face of such high-level instructions, the captains of the two mobile bases and the officers in charge of the two mobile bases naturally will not have any defiance and discount, driving the two mobile bases to the South without stopping.


    However, the senior management also learned that the supplies of the two mobile bases were running out, so they specially sent two helicopters to transport the supplies.


    "What do you mean by that? Aren''t you going to support Lucia? " Standing in the hangar, facing the cold wind outside, Chen Xin inquired with the officers beside him as he watched the two helicopters land on the extended tarmac.


    Since receiving instructions from the top, he has never let Chen Xin out of his sight. Except for Chen Xin eating and sleeping, he has been following.


    Now hearing Chen Xin''s question, the officer thought about it a little and said, "maybe the high-level officials have high-level considerations. To be honest, we don''t have much power to rescue Lucia. It''s not before the disaster. The most we can do is to send a medical team to study the situation of the virus and bring back the dog trapped there."


    Chen Xin has no other opinions about the officer''s reply.


    Indeed, as the officers said, the help that Yan could provide to Lucia was extremely limited.


    The shortage of domestic materials and medical resources will not be mentioned. Although it is not impossible to squeeze out at all, providing a medical team to help Lucia may be the limit that the senior management can achieve.


    As for shuogu, although the loss of an ark is heartbreaking, and those compatriots who are infected with the disease and trapped in Lucia are also worth saving, if saving shuogu means risking the whole country of Yan to spread the disease to China, Chen Xin thinks that the high level will make the right decision.


    Maybe cruel, maybe cold, but in the face of the safety of the whole country, the individual sometimes really insignificant.


    Of course, Chen Xin feels that things are far from here.


    After all, according to the high-level report, although Lucia had a large-scale spread of the disease, the death rate of the disease was not too high.


    In the absence of medicine, the mortality rate of those infected in Lucia is still at a low level, not even higher than that of influenza.


    Therefore, on the premise that the situation is relatively safe, the state is likely to send a medical team to Lucia to provide support for Lucia on the one hand and bring the dog back on the other.


    However, although the mortality rate caused by the outbreak of ancient virus in Lucia is not high, it does not mean that this virus is not dangerous.On the contrary, for viruses, the high fatality rate is not as terrible as expected. What is really terrible is the virus with high infectivity and high fatality rate.


    A virus has a high mortality rate, which can only show that the human body as the host is extremely incompatible with this virus, and it is easy to cause the rapid death of the infected person.


    The virus needs to self replicate and spread. If the infected person dies quickly, even faster than the speed of transmission, it is likely that the infected person will die before the epidemic has spread in a large scale.


    In this case, although it is said that the infected person will die quickly, resulting in a very high mortality, but the scope of infection is not very large.


    In fact, a "perfect" virus had better have a low mortality rate and extremely high infectivity, just like the well-known influenza. This virus has a high infectivity and relatively low mortality rate that spreads all over the world every year, so that there is hardly any good way to eradicate it.


    Therefore, a virus with a high fatality rate is not terrible, because it does not even have enough time to mutate, and it is easy to arouse vigilance. Although it is highly destructive, its scope of influence is relatively small.


    But highly transmissible viruses are dangerous. They are likely to spread quickly in a short time, and then start to mutate because there are enough infected individuals.


    With enough infected individuals, you can''t even imagine how many variants a virus can produce.


    Just like the epidemic situation before the disaster, the populous country in the South exposed the news that 7684 variants of the same virus were found.


    In this scale of mutation, only God knows what the virus will look like. Maybe the result of winning the first prize in the lottery will mutate into a highly pathogenic, lethal and easily transmitted super virus.


    For the outbreak of the ancient virus in Lucia, perhaps Yanguo can ignore its influence by relying on its long distance and cold weather, but what if a similar situation happens in China?


    So it''s good to send a medical team to Lucia to accumulate experience in dealing with the spread of ancient viruses.

 Chapter 489

    After another two days, the two mobile bases finally sent Chen Xin back to his home.


    The two mobile machines are also parked outside the research center, and will be further studied and tested, so as to develop other models and supplement vehicles at the same time.


    As for the large amount of information they brought back and the experimental weapons of the suvian era, the weapons research laboratory of the scientific research center will also take over the task of analysis and research, sorting out and archiving all the information, and then sending it to other research institutions.


    "I''ve come back from this trip." Back to his own site, from the mobile base down, Chen Xin can''t help feeling a word.


    Originally, he just went to test the air bag ark, but it turned into a disaster relief. After the disaster relief, he was pulled to Siberia for a turn. Now he finally went home, which made Chen Xin feel a little tired.


    However, despite this, Chen Xin did not go back to rest, but went to the laboratory of the research center. He had some ideas that needed to be put into practice immediately.


    In the two days after Chen Xin''s return, the senior management decided to send a medical team to Lucia. On the one hand, they really couldn''t help each other. On the other hand, they wanted to bring back the dog trapped in Lucia.


    Although the top management sent a medical team, the main task of the medical team was to bring the dog back and study the ancient virus spreading in Lucia.


    As for the assistance to Lucia, we can only say how much we can do in terms of personnel and destiny.


    What Chen Xin has to do here is to provide a set of reliable medical equipment for the medical team, so that they will not be infected with the disease themselves in the epidemic area of Lucia. At the same time, they can better isolate and analyze the ancient virus strains, and can quickly detect, diagnose and treat the patients.


    At first glance, it seems that Chen Xin is going to move a medical laboratory and a full set of medical equipment for the medical team, but in fact, when Chen Xin completed the whole set of medical equipment in the laboratory, they only packed a suitcase.


    The doctor who came to accept this set of medical equipment looked at the suitcase handed over to him, and his face was very surprised. He didn''t quite understand why he said that he would come to receive a set of medical equipment, but there was only one suitcase.


    Seeing the puzzled expression of the doctor who came to receive the equipment, Chen Xin opened the box in front of him and introduced the contents to him.


    There are only five pieces of equipment in the box, two of which are like instruments in hand, and the other three are like chest protectors that can be put on the chest after unfolding.


    "This is a three recorder. It has many functions, but it is mainly used to scan the human body for rapid detection." Chen Xin picked up one of the handheld devices and introduced it to the doctor: "I know that there are similar things in medical devices now, but the functions are not as comprehensive as this.


    This three recorder can scan more than 20 human conditions, such as breathing, heartbeat, body temperature, hormones, blood, bones, viscera, etc.. Generally, the physical examination report can be obtained only after a complete set of physical examination. With this, you only need to scan the target to get the result, just like this... "


    Chen Xin said, He scanned the doctor in front of him with the three recorder, then took a look at the screen on the three recorder, picked his eyebrows and said, "it seems that you have some low blood sugar and malnutrition? The heartbeat is a little fast, and other data are quite normal. "


    With that, Chen Xin handed the three recorders to the doctor and motioned him to see for himself.


    The doctor took the three recorder and took a look at the display screen. The doctor found that all his physical data were displayed on it, and his health status could be clearly seen.


    In addition, there is a CT and X-ray button beside the display screen of the three recorder. After the doctor presses down, a transparent human shape is projected on the top of the display screen of the three recorder, and there is a light screen on the head of the human shape, so that the doctor doesn''t know what this is for.


    "You can pull the light curtain to any part of the figure with your finger, and the instrument will display the CT image and X-ray image of this part." As Chen Xin explained, he raised his hand and operated on the projected human form.


    With his dragging, the light screen on the head of the human body swept the human body, and the CT image and X-ray image of the corresponding part of the human body were projected on the side.


    "Isn''t that convenient?" The doctor was pleasantly surprised that such a convenient instrument really helped them a lot.


    However, surprised by the new equipment, the doctor also asked, "is this X-ray imaging using X-ray? So direct irradiation should be very dangerous? "


    "Rest assured, the three recorders use the scanning beam which is harmless to the human body and will not cause harm to the human body." Chen Xin understands the doctor''s worries.


    After all, X-ray is a radioactive ray, which will cause harm to human body in the process of penetrating human body. X-ray machines in hospitals can only be operated in rooms covered with lead plates, so it is not a safe method to directly irradiate human body with hands.So when making the three recorders, Chen Xin has replaced the scanning beam with the beam that is harmless to the human body, which will not cause adverse effects on the human body.


    Moreover, the scanning beam can also analyze the chemical composition of the target, detect the secretion of various hormones in the human body and the content of various trace elements in the human body, and the detection effect is even better than that of blood examination.


    After listening to Chen Xin''s explanation, the doctor accepted the instrument at ease and said happily: "this is really great. With this three recorder, if we do the test, we don''t need the trouble of sampling and testing. We can directly get the results and know everyone''s physical condition."


    "Time is limited, so we only made two three recorders, and the other three are human body restoration devices." Chen Xin said that he took out another instrument in the box: "this instrument should be unfolded in this way, and then placed on the chest of the human body."


    As he spoke, Chen Xin unfolded the instrument and drew a position on himself: "after putting it in place, there is an automatic matching function on the three recorder. Just connect the instrument with the three recorder, and you can operate the instrument to repair the human body.


    The main function of this thing is to repair human body damage. At present, it is mainly used to repair trauma and internal organ damage. Its function is limited. You can make do with it. "


    "Just put it on? Isn''t that exaggerating? " The doctor doesn''t think it''s a disposable instrument that can directly repair human injury. Let alone having seen it, he hasn''t even heard of it.


    "It''s just that the self-healing of the body is promoted by radiation. It''s useless for many diseases, and it''s not suitable for all situations. It''s still very limited." Chen Xin is very modest about this.

    After giving the medical equipment to the doctor to take away, Chen Xin temporarily put down his attention to the matter.


    After all, even if the state sends a medical team to Lucia, it will take time for them to get there. Haizhu was designed by Chen Xin, and we still know its performance. This kind of large air bag aircraft can fly as fast as 80kmh.


    However, although Chen Xin has given up his attention to this matter, he is still thinking about relevant issues.


    In the shelter, Chen Xin sits on the sofa in the living room, in front of the structural projection of a dome type ground shelter currently being built in the disaster area by the state.


    "It''s easy to isolate the external infection source by improving the air filtration system, but the human body carries the virus..." Chen Xin is thinking about how to resist the virus in the shelter.


    The spread of air, water or other substances is easy to solve, but if the human body does not appear disease, just carrying the virus, it is difficult to detect and find.


    If Chen Xin lives in this kind of private small shelter, it''s OK. After all, there are few people, so we can monitor everyone''s health in real time.


    But if it is the kind of refuge for tens of thousands or even tens of thousands of people, it is unrealistic to want to monitor the physical condition of everyone in real time.


    Even if detection equipment can be installed at the entrance and exit of the shelter to strictly inspect all the people entering and leaving the shelter, if the infected person does not get sick and the virus is in the incubation period in his body, it is difficult to detect it without symptoms.


    It''s like a restaurant with an electronic temperature sensor installed at the door. Only people with high body temperature will be alerted by the instrument to remind the waiter to stop them.


    But if a person''s body temperature is normal, but there is a virus latent in his body, under such a condition, the instrument can not detect the virus in his body.


    The effect of Chen Xin''s three recorders is similar. All it can do is to detect the data of a person''s body. If any data deviates from the normal value, it can be easily found and treated.


    So for this problem, Chen Xin feels very headache.


    After all, what we have to face is the ancient virus. If it becomes highly infectious and infects a person, it can infect a whole shelter, or even spread between shelters, the consequences will be very serious.


    "What should we do?" Chen Xin felt very difficult and frowned.


    "What are you doing? A man is frowning here. " Mo Qingyan''s voice came from behind Chen Xin. She sat down beside Chen Xin and looked at him frowning. She was very concerned about him.


    "Thinking about how to improve the shelter." Chen Xin takes a look at Mo Qingyan, rubs her stiff face and leans on the sofa.


    Hearing Chen Xin say so, Mo Qingyan can''t help but feel a little curious, so she asks, "what''s wrong with this shelter? Doesn''t it look good? "


    "It''s very good, but there are still some shortcomings." Chen Xin explained to Mo Qingyan that maybe he thought that talking to Mo Qingyan would help to adjust his thinking. He pointed to the projection in front of him and said, "didn''t I go to Lucia before? There is an ancient virus spreading over there. The situation is quite serious. Although it can not affect us for the time being, we are well prepared. So I''m thinking about how to improve the protective measures of the shelter to prevent the spread of the virus. "


    As for Chen Xin''s idea, Mo Qingyan can''t help picking her eyebrows: "but the problem is that it''s hard to block the spread of the virus simply by relying on the protection of the shelter, right? As long as there is still a flow of people, there is still a way to spread the virus.


    Unless you completely close up the whole shelter, cut off the communication with the outside people, even if someone wants to go out, put on a full set of protective equipment, it is possible to avoid infection, but it is not absolutely no problem


    Because my sister is a medical student, and before the meteorite impact, there was an epidemic in Yanguo. Mo Qingyan knew about this aspect, and soon felt that Chen Xin''s idea was unlikely.


    "Yes, that''s what worries me." Chen Xin nodded, which is exactly where he felt embarrassed: "we can''t restrict people to leave the shelter, and the flow of people will certainly provide a way for the spread of the virus.


    My original idea is to install detection equipment at the entrance of each refuge, but this can only find out the infected people who have already contracted the disease, but can not find out the infected people in the incubation period, or can not stop the spread of the virus, and it is not realistic to install monitoring equipment in the refuge to monitor the health status of all people in real time, so I feel very difficult! "


    Listening to Chen Xin''s words, Mo Qingyan asked strangely, "ah Xin, is your idea a bit of a corner? And isn''t it easy to monitor everyone''s health through testing equipment? "


    "Easy?" Chen Xin looks at Mo Qingyan and doesn''t know why she says that."Wait a minute!" Mo Qingyan ran back to her room and quickly got something. After she came back, she said to Chen Xin, "ah Xin, look at this. This is the health bracelet I bought before. It can monitor my health in real time, but now it''s no longer available.


    When you say you can''t monitor everyone''s health, you mean covering the whole shelter with equipment and monitoring everyone in real time?


    That''s really hard, but if you use this, it''s OK! You just need to make sure that each person has one, who can monitor their physical condition at any time, who has physical problems, report to the police in time, and send a signal to the medical department or the management department? "


    Looking at Mo Qingyan''s health bracelet, Chen Xin suddenly has a kind of feeling.


    It''s really unrealistic to want to monitor everyone in the shelter in real time, but it''s still very easy to give everyone a healthy bracelet that can detect their physical condition at any time.


    As long as everyone is equipped with a bracelet that can detect their health status, when they find problems in their health status, they can mark them in time through the bracelet, and then another form of real-time detection of everyone''s health status can be achieved.


    In this way, although the possibility of virus transmission can not be completely eliminated, it can at least be found as long as someone gets sick, and the possible harm caused by the virus can be minimized.


    Thinking of this, Chen Xin jumped up from the sofa excitedly, hugged Mo Qingyan''s face and gave him a kiss. He said happily, "Qingyan, you''ve really helped me a lot! In this way, my biggest worry will be solved! "


    Mo Qingyan was startled by Chen Xin''s action, but looking at his happy appearance, she was also happy for Chen Xin''s happiness.

 Chapter 491

    Awakened by Mo Qingyan, Chen Xin soon completed the idea of a healthy bracelet.


    It''s not complicated to make this thing. Long before the meteorite fell, there were enough mature products on the market. What Chen Xin wanted to do was to improve it.


    To put it bluntly, this kind of bracelet is an inductive patch plus a computing chip, which can sense the data of human heartbeat, body temperature, etc. through the inductive patch, the chip is used to process the data sensed by the inductive patch, calculate and judge your physical condition.


    As for the alarm function, it only needs to preset a value in the chip. When the monitored data deviates from this value, the chip will automatically alarm without additional operation.


    The only problem is that there is no network signal covering every corner of the streets as in the past. The alarm function of the bracelet can only work in the shelter.


    However, this problem is not big. Chen Xin''s main purpose is to monitor the health of the people in the shelter and whether the people in and out of the shelter have health problems. As long as the people in the shelter can report to the police in time, this bracelet will work.


    As for the spread of the virus caused by the flow of people, this problem is not inevitable.


    The protective clothing designed by Chen Xin before has the ability to block viruses. After all, the whole protective clothing is designed to be totally enclosed, relying on the air filter module to filter the external air and block harmful substances. As long as you wear the protective clothing, you will not be at risk of infection.


    In terms of protective clothing, although limited by the problem of production capacity, even if it is vigorously promoted by the state, it still does not have one person, which can only ensure the use of outdoor work, but on the whole it is enough.


    So as long as everyone is equipped with a health bracelet to monitor their physical condition, outdoor work can do a good job of protection, in theory, epidemic prevention is no big problem.


    However, when Chen Xin made the bracelet and talked about it with other researchers in the laboratory, the other side was not optimistic about it.


    "Academician Chen, your idea is very good, but..." the researcher seemed a little hesitant, hesitated for a while, and then said: "the country should not have enough production capacity to make this so-called healthy Bracelet now, right?"


    "National capacity is not enough?" Chen Xin frowned. Although he knew that the state was in short supply, he could not even make a small bracelet, could he?


    Chen Xin frowned and asked the researchers his own question, but the researchers could only reluctantly answer: "a small bracelet is of course made by the country, but academician Chen, you should design a healthy bracelet for everyone in the country, right?


    The country''s main industrial capacity is now used to support the reconstruction of the southwest region. Of course, there is no problem in small batch production of some health bracelets, but if you want to have one person, I''m afraid you can''t free up such a large capacity before the reconstruction of the southwest region is completed. "


    "What about batch production? It''s impossible to say that we won''t do it because of insufficient production capacity? " Chen Xin asked, frowning.


    In Chen Xin''s view, this is a preparation for the prevention of the possible spread of epidemic diseases. It is an inevitable epidemic prevention system. If we do not do this just because of insufficient production capacity, he really can not accept it.


    Hearing Chen Xin say small batch production, the researchers nodded: "this is no problem, how to produce a batch of bracelets is still OK, but the specific amount of production depends on the overall arrangement of the country."


    This is also the current situation. All industrial production capacity is allocated by the state, as if everything is back to the era of planned economy.


    This is also an inevitability. After all, in this situation, further market competition will only waste precious resources and production capacity, and can not maximize the use of limited resources.


    If the state regulates everything as a whole, it will be able to use resources to places in urgent need, and at the same time, it will be more comprehensive and planned.


    Chen Xin also knows about the shortage of national resources. Otherwise, he would not have made Titan, which consumes a lot of resources, in order to apply it to industrial production such as mineral mining and obtain higher production capacity instead of human resources.


    Just did not expect Titan as an industrial machinery design, has not been applied to industrial production, first used in disaster relief.


    However, we have to say that the applicability of Titan is really good. From the feedback from the disaster area, Titan has played a great role in the reconstruction of the disaster area.


    This also makes Chen Xin seriously consider whether to design a special model for disaster relief in the subsequent development of Titan.


    Of course, this idea can only be regarded as a plan. At present, all Titans, except Qin Lan''s, are still in the disaster area. Even if we need to develop follow-up models, we can develop them according to the collected data after these bodies come back.After all, the Titans Chen Xin is making are all from the materials in the game and the brain holes of researchers at the development stage.


    Therefore, it is necessary to adjust the deficiencies and irrationalities, or to extend the design to other models, and to improve the specialization of specialized models according to the actual data collected.


    However, considering the actual use needs of Titan, Chen Xin thinks that mining, industrial and disaster relief should be the top priority in the follow-up development.


    The reason why we consider developing these three models is mainly because of what the researchers have just said.


    The country''s industrial capacity is insufficient, which is not only the loss of a large number of factories and equipment caused by the meteorite fall, but also the shortage of raw materials.


    After all, after the disaster, the original production capacity of industrial raw materials will be greatly affected, such as crude oil, coal, metal ores and non-metal ores. Tuoyan has a vast territory and abundant resources. Although it has been greatly affected, it is still able to restore domestic production and meet the needs of industrial production.


    However, agricultural products such as logs, natural rubber and raw cotton have been greatly affected. Many of them have been unable to recover in a short period of time or can not be recovered at all, which also has a great impact on industrial production.


    Although the dependence of modern industry on agricultural raw materials is gradually decreasing with the development of science and technology, and many raw materials can be replaced by chemically synthesized products, this situation is also not optimistic when the chemical production capacity is also affected.


    In this case, if we can improve the production capacity of raw materials and industrial production efficiency, it will greatly promote the recovery of the overall industrial capacity.

 Chapter 492

    In the shelter, Chen Xin is rarely busy in the kitchen.


    Since taking charge of the research center, he has had little time to cook by himself.


    On the one hand, there are too many things to do, so when you are busy every day, you seldom have time to cook by yourself. On the other hand, because the whole scientific research center has a complete logistics support system, you can eat without him cooking in person.


    And cooking in person has become a kind of leisure that Chen Xin uses occasionally to relax himself.


    Of course, this so-called "leisure" is extremely luxurious in today''s environment.


    After all, even if Yanguo now can ensure that ordinary people do not worry about food and drink, Chen Xin''s previous research on ecological agriculture has achieved certain results, but it only enables ordinary people to have enough to eat.


    It''s almost impossible to eat what you want and eat well, just like before the disaster.


    It''s hard to have enough food and clothing for three meals. It''s not impossible, but it''s also very hard to see Chen Xin doing something he wants to eat.


    Taking an ordinary family of three as an example, if both husband and wife have jobs and can get extra food rations, the quota obtained by working hard for one month can not only meet the daily needs of three people, but also save a little to exchange some fresh vegetables, fruits or meat to improve the food.


    It''s just like ordinary people in the 1980s and 1990s of the Republic of Yan ate meat once or twice a week. It belongs to improving food, not daily life.


    As for Chen Xin, even if not counting the ecological greenhouse of the research center outside, it''s just his own greenhouse that can keep vegetables and fruits growing every day.


    In terms of meat production, although there is only one kind of chicken, and the quantity is limited, it is impossible to kill chickens every three or five times, but ten days and a half months can still kill a chicken to eat, and eggs are enough.


    What''s more, Chen Xin can get extra special rations every month, which is enough to satisfy him in terms of food security.


    This also makes Chen Xin have the ability to cook on his own when the goods are in short supply, and regard it as a kind of relaxation.


    However, although there is no shortage of materials on hand, Chen''s dishes are not many. He just fried two small dishes and stewed a pot of soup.


    "Why are you in the mood to cook today? I haven''t seen you cooking for a long time. " Passing by Qin LAN smelled the taste of food, went to the kitchen, looked at Chen Xin placed on the table of food, curious asked a sentence.


    Chen Xin smiles and brings down the soup pot on the stove. Then he says to Qin LAN, "I just came back from work. I was hungry and wanted to have a snack. When I saw that there were some materials in the refrigerator, I decided to make a snack and have a drink. Recently, I was a little too tired. Why haven''t you slept yet


    "A little sleepless." Qin LAN shook her head, took two cups from the cabinet, and sat down at the table.


    "What''s on your mind recently?" Chen Xin took out the wine that he was going to drink by himself, poured a cup for Qin LAN, and then asked about her.


    Chen Xin remembers that before she went to Lucia, Qin LAN seemed to have something to say to herself, but she didn''t say it because she was interrupted.


    Looking at Qin Lan''s present appearance, Chen Xin thinks that she should have something on her mind, and has not found a suitable opportunity to tell herself, so she takes the initiative to ask.


    See Chen Xin asked, Qin LAN Leng for a while, this just nodded: "it''s about marriage."


    "Marriage?" But Chen Xin was stunned. Qin LAN would suddenly talk about marriage, which really exceeded his expectation: "how can we talk about this well?"


    "It''s auntie." Qin LAN raised her cup and took a sip. Then she continued: "when I went to the southwest, my aunt asked me and Qing Yan when you would get married."


    When Qin Lan said this, the whole person blushed, but still looked up at Chen Xin seriously, looking forward to his reply.


    "Ah? This... "Chen Xin didn''t expect that Qin LAN would suddenly talk about it.


    After all, he now strictly has two girlfriends. According to the law of the country, he can only marry one. Anyone who marries will be sorry for the other.


    As for the two married home what, in fact, and now there is no big difference, nothing more than a matter of fame.


    However, this problem is not easy to solve. Even though Chen Xin has made a lot of contributions to the country and can enjoy special treatment, this special treatment is not enough to allow him to marry two wives. Therefore, Chen Xin has never considered this matter.


    And Qin LAN and Mo Qingyan are also out of the same consideration, and don''t force Chen Xin to say what to get married.However, none of the three people thought that Chen Xin''s mother would suddenly ask about it, which made Qin LAN and Mo Qingyan do not know how to deal with it.


    Mo Qingyan chooses to pretend to be dead and doesn''t talk about it. Instead, she thinks it''s better to maintain the status quo, and no one will feel uncomfortable.


    As for Qin LAN, although she thinks it''s better to maintain the status quo, she still plans to talk about it with Chen Xin.


    And most importantly, she never thought about marrying Chen Xin.


    Anyway, when she and Chen Xin were dating, they both developed into cohabitation. The matter of marriage had been considered more or less before.


    Later, they get together again. Qin LAN doesn''t want to marry Chen Xin, which is impossible.


    Although the acquiescence of the relationship between the three people now, but there will be a little unwilling.


    But Qin Lan also knows that if she has to come up with a result, it is very likely that only three people will be unhappy, so she just mentions it with Chen Xin and doesn''t want to do anything about it.


    Chen Xin certainly knows what Qin LAN means and what his attitude is, but he can''t make any stand on this matter.


    "My mother, she..." Chen Xin wants to say something, but finds that he can''t say anything. Finally, he can only say to Qin LAN: "I will tell my mother about this."


    "Auntie is mainly concerned about you, I hope you can live a happy life." Qin Lan was afraid that Chen Xin and his mother would have any disputes, so she added: "so don''t talk to your aunt, ah Xin, just follow her meaning, as for this..."


    Qin Lan said here, did not continue to say.


    Although I really want to tell Chen Xin that I don''t mind, it''s impossible that I don''t mind.


    "I''ve wronged you and Qing Yan." Chen Xin saw Qin Lan''s picture, what else she didn''t understand, and comforted her.


    But this kind of comfort is too light, let Chen Xin always feel that he owes Qin LAN, also owes Mo Qingyan.

 Chapter 493

    For Chen Xin, there are many things he needs to deal with every day. Although he is not overworked, he has little time to rest and relax.


    In addition to the leisure time after he went back to his residence after the research center, he occasionally sat down under the ecological dome of the research center and had a cup of tea when he was busy dealing with all kinds of things.


    Tea is the output of the ecological dome. After the ecological dome was put into use, the biological research team planted many plants here, including several tea trees.


    Although there is very little tea that can be harvested, Chen Xin still gets some. Occasionally, he throws a few pieces into the cup to soak them. Then he sits in the rest area under the ecological dome and relaxes himself a little.


    Now the construction of the ecological dome and the planting of plants have been completed. Relying on the energy provided by the geothermal power plant on one side, the effect of sunlight in the past is simulated here to provide photosynthesis for these plants and illumination for the whole ecological dome.


    Because the mode of simulating natural light is adopted, and there are many green plants with luxuriant branches and leaves around, the rest area under the ecological dome has the flavor of before disaster.


    When people sit here, they will occasionally unconsciously forget that it is the cold winter of the long night after the meteorite fall, and they think that they are enjoying a leisurely lunch break and afternoon tea before the disaster.


    If you just look up, the black sky outside the transparent dome will remind you that it is still the end of the world.


    For Chen Xin, of course, he doesn''t forget that it''s the end of the world. After all, in terms of being able to let people forget the present predicament and re experience the beauty before the disaster, the hologram room he built for himself in the refuge is much better than here.


    So for Chen Xin, the rest area of the ecological dome is just a place where he can sit down and rest between work.


    Although his shelter and research center are separated by a corridor, Chen Xin is still not used to going back to rest during working hours. Even lunch is basically eaten with everyone in the canteen of the research center, and seldom goes home to eat.


    At most, I will come to the rest area to have a rest after lunch.


    Other people in the research center also know Chen Xin''s habit. When he has a lunch break, he usually doesn''t disturb him. Even other people who also choose to come to the rest area at noon will try their best to avoid Chen Xin and won''t disturb him.


    However, there seems to be an exception today. During Chen Xin''s break, someone came to find him and broke his silence during his lunch break.


    "Ingredients, I''ve brought you something delicious. Would you like to try it?" Mo Qingyan sat down in front of Chen Xin with a smile and put a covered plate on the small table in front of him.


    "Food? What''s that? Still so mysterious? " Chen Xin saw Mo Qingyan''s arrival, but he didn''t mind her disturbing his lunch break. He just looked curiously at the covered plate on the table and asked her, "what''s the matter with the cover so that I can''t see it?"


    With that, Chen Xin wants to reach out and lift the lid, but Mo Qingyan holds the lid down and says with a smile to Chen Xin, "it''s delicious, but you have to guess it right before you can eat it. If you don''t guess it right, you won''t be given it!"


    "Well? What are you doing? Don''t you give it to me? " Chen Xin looks at Mo Qingyan''s hand holding the lid, and her face is a little sad.


    "Guess! I put a lot of effort into it. How can you eat it so easily? " Mo Qingyan is still smiling, but she still insists on letting Chen Xin guess.


    In the face of Mo Qingyan''s attitude, Chen Xin felt helpless for a while. He could only follow Mo Qingyan''s meaning and asked, "if you let me guess, why don''t you give me some hints? Just cover it like this, let me guess, I can''t guess what it is. "


    "I''ll give you a hint and you''ll guess. That''s boring." Mo Qingyan refuses Chen Xin''s request, and the smile on her face is full of confidence.


    "No hint?" Chen Xin touched his chin and looked at the plate on the table: "this plate is not big, and you use a shallow cover. It should not be a big thing, and it doesn''t look like it''s covered for heat preservation, so it shouldn''t be a hot thing."


    Chen Xin tried to analyze it, and at the same time, he reached out and touched the cover of the plate. Sure enough, the cover was not hot.


    Seeing that Chen Xin starts to guess the things on the plate, Mo Qingyan''s smile is more brilliant. It seems that Chen Xin can''t guess what''s inside.


    However, Chen Xin took a look at her fingers, lowered his head, sniffed her clothes twice, and then said in surprise, "is it a cake? Where did you get the flour? "


    In the current situation of material shortage, cake is a luxury. After all, both eggs and milk are scarce. Chen Xin relies on the special supplies provided by the state to get some dairy products every month.In terms of flour, there was flour in the special supplies Chen Xin would receive every month. However, in recent two months, there has been a shortage of flour, resulting in no flour in Chen Xin.


    In fact, the situation is also simple. Because of the earthquake in Southwest China, the state transferred the grain storage to support the disaster area, and the flour that should have been distributed naturally disappeared.


    Now Mo Qingyan suddenly made a cake for him, which surprised Chen Xin.


    "You guessed it!" For Chen Xin to guess the answer so simply, Mo Qingyan seems to be a little disappointed, but still opened the lid, revealing inside a not too exquisite workmanship, but also covered with a layer of cream cake, the top also specially coated with a layer of strawberry jam: "the material is not much, I only made a small one, you try it, the taste should be good."


    With that, Mo Qingyan takes out a small fork from her body and hands it to Chen Xin.


    "Where did you get the flour? I remember there should be no flour at home, right? And there''s only a little sugar left. Don''t you use all the sugar? " Chen Xin is not surprised by the cake itself, but is more curious about where Mo Qingyan comes from to make the cake flour.


    "Don''t worry! I didn''t move your candy. The materials of this cake are all processed by the things planted in the ecological greenhouse. They want to give you a surprise. " Mo Qingyan explained to Chen Xin, urging him: "try it! I''ve been making this cake all morning! "


    Hearing what Mo Qingyan said, Chen Xin had to let go of his curiosity about the situation in the ecological greenhouse, cut a piece of cake with a fork and put it in his mouth.

 Chapter 494

    Ecological greenhouse is a research project established at the beginning of the establishment of scientific research center.


    Although the term "ecological greenhouse" has been used for a long time, and some people have been studying ecological agriculture and greenhouse planting before the meteorite fall, and there is no research combining the two, these ecological greenhouses are totally different from the ecological greenhouses in the research center.


    Before the disaster, the so-called ecological greenhouse was a system composed of various plants planted in the greenhouse, various animals, microorganisms and various natural factors.


    Although it can also form a relatively stable ecological cycle, most of the sunlight, air and water need to be imported from the outside world.


    In particular, the most important sunshine, which can almost be said to be an indispensable resource for all agricultural production before the disaster.


    However, with a series of disasters caused by meteorite impact and the impact of recent volcanic eruption, sunlight has long disappeared, and even in the next decade or so, it can only recover to a low light level environment at most.


    Without sunlight, it is a huge blow to the whole agriculture. People have to use artificial light to provide light for crops in a way that consumes a lot of energy.


    For the past ecological greenhouse, such impact and blow is fatal.


    So Chen Xin would like to do research on ecological agriculture before, and build an ecological greenhouse that can adapt to the current environment.


    Fortunately, this research is very smooth. After all, it has the research foundation of the original ecological greenhouse, and now there are geothermal power stations to ensure the energy supply and the warmth of the greenhouse. It is not very difficult to adjust the mode of the original ecological greenhouse under the condition that all conditions are complete, so that it can adapt to the existing environment.


    In fact, after the establishment of the scientific research center, the research of ecological greenhouse has made a good breakthrough and progress under the team led by Professor Li sent by the state, and on this basis, the second phase of greenhouse expansion has been carried out.


    And according to the model of greenhouse, a new greenhouse was built in an old reform through labor farm in the urban area, which made the original farm play a role again.


    And after these greenhouses were built, they soon played their role and began to produce a variety of agricultural products stably.


    However, most of them are fruits and vegetables. Poultry and fish raised in greenhouses are not produced at the first time because of the time, so they need to be raised for a period of time to provide meat.


    As for the most important food crops, rice was chosen at the beginning.


    On the one hand, rice is the staple food in southern China, and people are used to eating rice instead of noodles. On the other hand, the whole greenhouse is built for the purpose of forming a stable ecological cycle and realizing permanent cultivation.


    Planting more than two kinds of main food crops rashly will occupy a lot of limited resources in greenhouse.


    Now, no more than in the past, after the loss of sunlight and major precipitation, especially the destruction of surface vegetation, the nutrients that the soil can provide have become limited. The cultivation of greenhouse must consider the overall ecological cycle.


    Although it is not that it is not impossible to plant a variety of major food crops by artificial supplement to produce a large amount of food, and the country does do so in some places to obtain a large amount of food, this method is still contrary to the purpose of ecological agriculture.


    After all, the purpose of ecological agriculture research is to restore the destroyed environment of Bluestar in the future, and rebuild the Bluestar ecology. If we use the method of fishing with all our efforts, although it can really solve the immediate problem, it is not a long-term plan.


    Therefore, even if the country needs a lot of grain now, it still supports Chen Xin''s ecological greenhouses instead of using a way more similar to traditional agriculture, relying on artificial input of chemical fertilizer, light, water and other conditions to produce grain on a large scale.


    However, after the realization of rice based ecological planting system, the team led by Professor Li also began to study another planting system based on wheat.


    This is mainly to enrich the variety of food, but also to meet the differences in diet structure between the north and south of Yan country.


    Although there is little difference now, there is a strong desire for ChiYan people. Since rice has been cultivated well, it is impossible to give up wheat.


    Chen Xin knows that Professor Li and his colleagues are studying the wheat planting system recently, but he thought it would take some time, but he didn''t expect that they really gave him a big surprise.


    When Chen xinlai came to the ecological greenhouse, Professor Li and his research team were watching the mechanical harvesting of wheat.


    "Professor Li!" Chen Xin came to Professor Li and said hello to the old professor. Then he looked at the wheat being harvested in front of him and asked in surprise, "is this batch of wheat ready to be harvested?""Yes, it''s growing very well. It''s estimated that the yield per mu will be 1000 Jin!" Professor Li is very happy about the bumper harvest of wheat in front of him. When Chen Xin asked, he said happily, "we didn''t interplant this batch of wheat for the sake of safety. Now that we can guarantee the yield, we can start the experiment of Interplanting Wheat with other crops in the next step."


    Wheat interplanting is a very common way of wheat planting before the disaster. Chen Xin also learned about the relevant technology for the sake of ecological greenhouse. At this time, he was surprised to hear Professor Li say so.


    So he asked Professor Li, "Professor, wheat interplanting is to make up for the lack of light and temperature in some areas, right? There is artificial light and temperature in the ecological greenhouse, so there should be no need for interplanting, right


    "No, it''s different. Traditional interplanting is really to solve the problem that wheat can only meet the requirement of one crop a year due to the lack of light and temperature in some areas of China. Interplanting other crops reduces the competition for light and temperature under the condition of two crops a year." Chen Xin''s problem is just Professor Li''s professional scope, which naturally makes the old professor want to explain to Chen Xin.


    He took Chen xinlai to a piece of wheat that had not been harvested, pointed to the space of the root part of the wheat plant, and said to him, "the ecological greenhouse planting that we are using now can provide sufficient light and temperature, so the purpose of interplanting is not to reduce the competition for light and temperature, but to make full use of the planting space, At the same time, increase the grain yield per unit area.


    Now the traditional planting spacing is adopted for these wheat, and then we will adjust the spacing wider. Although the wheat planted will be reduced, the total grain yield per unit area can be increased by interplanting other crops, so interplanting is still very meaningful! "

 Chapter 495

    The ecological greenhouse of the research center is not the same as the traditional greenhouse, but also different from the ecological greenhouse before the disaster.


    The traditional greenhouse is mainly used to raise the temperature and artificially change the growing environment of crops.


    Although the ecological greenhouses before the disaster are different, they are actually used for this purpose, but relatively speaking, their functions will be more comprehensive.


    Chen Xin remembers that according to the information he found, there are even ecological greenhouses with solar panels, which provide energy for the greenhouses through solar power generation, and make full use of natural resources to improve the yield of crops in the greenhouses.


    But now it''s all out of the question.


    Including the new greenhouses built by the state, the most essential difference between these greenhouses built after the disaster and those built in the past is still on the walls.


    Most of the traditional greenhouses are made of transparent film, which is low cost and easy to maintain. Straw mulch or thermal insulation quilt is used to keep the temperature. In the past, it is enough to keep the temperature.


    However, if you want to maintain the temperature in the environment of tens of degrees below zero, this is not what the traditional greenhouses can do. Even in the past, the ecological greenhouses mostly used organic glass, transparent plastic and other materials in building materials, and the thermal insulation performance did not exceed too much.


    The four walls of the greenhouse in the scientific research center are all made of high-performance thermal insulation materials as interlayer, the outer layer is made of low temperature resistant metal materials, and the inner layer is made of composite materials. The three-layer structure can not only resist the invasion of external cold, but also prevent the loss of internal temperature and water vapor.


    Because there is no sunlight outside, so now the ecological greenhouse does not consider the problem of light transmittance, but in order to save as much as possible to reduce the escape.


    In addition to the structural differences, the greater difference lies in the interior.


    It not only uses a variety of technologies such as soilless cultivation, three-dimensional planting, ecological agriculture and breeding to upgrade the original plane planting area into a three-dimensional planting system, but also forms a cycle between various crops to form an organic whole.


    With the continuous supplement of the three necessary conditions of light, warm water, the ecological greenhouse of the scientific research center can not be said to be able to cultivate indefinitely, but there will be no problem in at least ten or twenty years.


    The goal of the research team led by Professor Li is that there will be no circulation problem within 50 years, and that the ecological greenhouse can still operate normally without changing crops except for mechanical maintenance.


    As for the maintenance of ecological greenhouses, it has been fully mechanized with the help of Chen Xin.


    Mechanical harvesting, mechanical sowing, mechanical irrigation, mechanical feeding... Under Chen Xin''s will, all the parts requiring human labor in the whole ecological agriculture system have been replaced by mechanized operation, and everything has become automation.


    As a matter of fact, the ecological greenhouse in the scientific research center is also fully automatic. Just set up the planting mode and ecological system, provide the original crop seeds and animal seedlings, and ensure the supply of light, temperature and water, so that the whole ecological greenhouse can operate on its own.


    Professor Li''s pursuit of 50 years without problems means that the whole ecological greenhouse can operate for 50 years without problems except for mechanical failures.


    In order to achieve this goal, Professor Li and his team have carefully selected all the crop seeds.


    They did not choose the seeds that were artificially bred in the past with high yield but could not inherit the traits for a long time, but the seeds that had stable traits and could be sown all the time without obvious yield reduction.


    Moreover, the ecological dependence between crops has been studied in detail, which can build the fully automated ecological greenhouse of the current scientific research center.


    With the help of Chen Xin''s equipment for breeding genetically modified wolf dogs, the animal seedlings used in the ecological greenhouse have optimized the traditional livestock seedlings and bred excellent breeds.


    It''s just that animals and plants are very different. They need special people to take care of them.


    Although the automatic machinery of the ecological greenhouse can provide them with the necessary water and food for survival, if there are diseases and other conditions, they still have to be handled by human beings.


    It has to be said that it has the flavor of automated agriculture in science fiction.


    And the ecological greenhouse, which has devoted a lot of efforts of Professor Li and Chen Xin, has not let them down. It can not only maintain itself all the time, but also continuously produce melons, fruits and vegetables every month, as well as a large number of agricultural and sideline products such as food crops, eggs, milk and meat.


    According to Chen Xin and Professor Li''s calculation, such a greenhouse can support at least 3-5 people per mu.


    Don''t think that this figure is very low. If we follow the traditional agricultural model, if we only grow rice in one mu of land, we can barely meet the needs of two or three people for rice if we plant 1000 catties of rice in two seasons a year and produce 500 or 600 catties of rice in one season and 1000 catties of rice in one year.But it is impossible for people to eat rice without vegetables or other meat.


    Therefore, theoretically speaking, if you want to support a person and meet his dietary needs, it is not enough to rely on one mu of land with traditional planting methods.


    And now this kind of ecological greenhouse can provide completely different.


    First of all, the ecological greenhouse which can carry out three-dimensional planting and ecological agriculture can completely turn the original one mu land into several mu land, and greatly increase the yield of crops.


    Moreover, the ecological system built in the ecological greenhouse can produce a wide range of vegetables and fruits, eggs, milk, meat and other agricultural and sideline products obtained by raising poultry and livestock.


    And the rich food types, especially the existence of meat, can greatly reduce people''s demand for a single grain.


    So just from how many people can be supported by one mu of land, of course, the ecological greenhouse is the winner.


    But correspondingly, the maintenance cost of ecological greenhouse has also been increased a lot.


    In traditional farming, one person can finish all the work in one mu.


    However, without the full-automatic machinery provided by Chen Xin and relying entirely on human resources, three or five people may not be able to maintain the operation of the ecological greenhouse with an area of one mu, and these people must have enough knowledge to enable them to deal with various problems.


    However, although the cost of investment is high, the ecological greenhouse is also a huge good news for the current situation in Yanguo.


    Because for Yanguo, the manpower needed to maintain the operation of an ecological greenhouse is secondary, and the main thing is to obtain more food output.


    After all, in the end of the world, manpower is not worth money, but food is very valuable.


    It is precisely because the first mock exam will give the eco high priority to the ecological greenhouse. It is intended to build a new ecological greenhouse in order to produce more food.

 Chapter 496

    Chen Xin, who got up in the morning after washing, dressed, had breakfast with his parents in the restaurant, and was ready to go out.


    "Ah Xin, are you going to inspect the ecological greenhouse on the other side of the reform through labor farm today?" However, when Chen Xinlin went out, Mo Qingyan suddenly stopped him: "can I go with you?"


    "I''m going to the farm, that''s right, but are you going with me, Qingyan?" Hearing Mo Qingyan say that she wants to go with her, Chen Xin feels a little strange.


    Under normal circumstances, neither Qin LAN nor Mo Qingyan will make such a request, because Chen Xin is going to work, and they have never made such a request that they will interfere with his work.


    However, Mo Qingyan clearly nodded: "want to see, can I go together?"


    Mo Qingyan said, looking forward to it, but a little worried.


    After thinking about it, Chen Xin felt that it didn''t matter to take her with him, so he agreed and said, "it''s OK to take you. Do you have anything to clean up? If it''s nothing, just go. "


    "Well!" Hearing that Chen Xin was willing to take her with her, Mo Qingyan quickly finished her breakfast, wiped her mouth and followed.


    The two left the shelter in the elevator, put on protective clothing, and then came to the research center together.


    On this side of the scientific research center, the team has been waiting for Chen Xin.


    Today, they are going to the reform through labor farm to inspect the construction and operation of the greenhouses and see if there are any problems that need to be improved. Therefore, in addition to Chen Xinhui, there are several researchers from Professor Li''s team.


    Originally, Professor Li wanted to go himself, but the old man was not in good health, so he was persuaded to change to some young researchers.


    After the meeting, the motorcade drove out of the research center and toward the reform through labor farm.


    The reform through labor farm is located on the other side of the city. It passes through the scientific research center and needs to pass through the city.


    The motorcade is advancing. There is no road to speak of now. The city is covered with snow.


    Except for several key places where snow was cleared to ensure that several main entrances to the urban shelters were not covered by snow, other places were covered by snow blown from the previous blizzard.


    As for transportation, we usually use roads built underground.


    After such a long time, all the official shelters in the city have been connected by the underground transportation network.


    Usually, the vehicle will drive underground, and will not be disturbed by the wind and snow from the ground. At the same time, it can also avoid the loss of low temperature to the vehicle in extremely cold environment.


    However, Chen Xin''s motorcade passed through the ground directly and did not enter the underground transportation network because the vehicles were all terrain vehicles.


    "I haven''t been downtown for a long time!" Sitting in the car, Mo Qingyan looked out of the window and couldn''t help sighing.


    Since moving to Chen Xin, she has not been to the city for a long time. As for her own home, it is still frozen under the snow and has not been treated.


    Hearing Mo Qingyan''s emotion, Chen Xin echoed: "it''s really a long time since I came here, and I haven''t seen Xiao Ding for a long time. I don''t know how she is now."


    Speaking of this, Chen Xin remembers that he has not seen his friends in the past for a long time. No matter Ding Ning, Li Yulong or Li Wensheng, Chen Xin has not seen them for a long time.


    It''s not that Chen Xin intended to alienate his friends, but that in the current environment, everyone is working hard for survival, and there is no time for everyone to get together.


    With this feeling, the motorcade passed through the city and drove for about two hours to reach their destination today.


    Before the disaster, the reform through labor farm was used to imprison petty criminals and carry out forced labor.


    After the disaster, because of the vicious change of the environment and various reasons, the reform through labor farm is no longer responsible for the labor reform of prisoners, and is basically abandoned.


    Among the prisoners who were originally held here, the remaining prisoners with shorter or the latest lighter term were pardoned and released, while the rest were transferred to other places and would participate in various kinds of labor together with the prisoners in other places.


    This is also the way the state deals with all kinds of criminals originally held after the disaster.


    Serious criminals can not be released. If they continue to be detained like this, they will consume a lot of resources. If they are allowed to work, they can provide a good labor force for the country.


    As for now, although greenhouses have been rebuilt on the original land of the reform through labor farm, the people who are responsible for maintaining the greenhouses are not criminals who were imprisoned before, but workers who have received special training.After all, because of the cost problem, we don''t use fully automated machinery, but only rely on manual operation of agricultural machinery to complete the work, but the ecological greenhouse still needs certain professional knowledge and work skills, which is obviously not enough by the prisoners.


    Coupled with the importance of ecological greenhouse, it is not suitable for prisoners to be the main labor force here.


    For the arrival of Chen Xin and others, the farm is naturally well prepared, specially arranged a special person to meet them, and took them to visit the greenhouse which has been built now.


    The whole farm used to have more than 30000 mu of arable land. Due to various disasters after the meteorite fall, less than 5000 mu of land has been cleared up for the ecological greenhouse, and only 3000 mu has been built. A considerable part of the land is being cleared up.


    Generally speaking, this is not a large area, but considering that the whole farm has been cleaned up and constructed again, that is, in the past half a year or so, it is very proud for Chen Xin to have this scale.


    The ecological greenhouse here adopts Chen Xin''s original idea, and a geothermal energy tower is built in the center of the farm to generate electricity and heat, so as to provide electricity and heat for the surrounding ecological greenhouse, so as to ensure the operation of the ecological greenhouse.


    As for the interior of the ecological greenhouse, it is more substantial than that of the scientific research center, because there are less mechanical parts and more crops.


    "Do you rely mainly on human resources now?" Chen Xin asked the accompanying staff.


    "At present, most of the work is done by manual operation of agricultural machinery, which belongs to semi mechanized labor. The overall amount of labor is not particularly large. On average, a 20 mu greenhouse only needs 6-8 people to complete all the work." The staff answered Chen Xin''s question and unconsciously expressed pride in his words: "we normally equip a greenhouse with six people for daily maintenance. When it''s time to harvest, we will add another two people to help harvest, which can fully ensure the operation and output of the greenhouse!"

 Chapter 497

    Everyone is satisfied with the current situation on the farm.


    Although the output of the farm is not much, as the surrounding land is constantly cleared out, the number of greenhouses and the amount of grain output will continue to increase.


    Now this piece of ecological greenhouse is just the beginning. With the national investment in food production, more and more new ecological greenhouses will be built, and more and more food will be produced.


    Just like the saying all the time, a single spark can start a prairie fire, and this ecological greenhouse that can still harvest food under the extreme night and winter is the spark that has been lit.


    He inspected the greenhouses in the farm and helped the farm workers solve some problems they encountered in the process of maintaining the operation of the greenhouses. It took almost a whole day for Chen Xin and others to complete the inspection and return to the research center.


    "The cost of the original full mechanical automation of the ecological greenhouse is really too high. I talked with those workers just now. They can maintain an area of 20 mu by six people, which is very meaningful!" Sitting on the bus back home, Chen Xin is talking with a researcher about the ecological greenhouse.


    Hearing Chen Xin''s words, the researcher nodded with approval: "fully automated mechanical harvesting can indeed save a lot of manpower investment, and also make the operation of greenhouse more scientific and efficient, but the investment is still too high. Two fully automated mechanized greenhouses are enough to build three non mechanized greenhouses of the same area."


    "That said, we still need mechanized greenhouses. If we don''t engage in full-automatic mechanization, we can try semi-automatic." Although Chen Xin also understands that the investment in fully automatic and mechanized ecological greenhouses is too high, he still feels that he can''t give up mechanization.


    The researcher who talked with Chen Xin agreed with this. He could understand Chen Xin''s meaning: "I also agree to appropriately improve the degree of automation. After all, there are six people in 20 mu of land and eight people in harvest. The labor cost is not low!"


    Although the current labor cost is not worth money, one mu of ecological greenhouse can support about three to five people, and only six people can maintain 20 mu of land. How to calculate, it is a matter of input exceeding output.


    But a lot of manpower investment also means that the corresponding logistics facilities have to keep up.


    After all, people have to have all kinds of needs to eat, drink and pull. Even if the conditions are a little harder now, all kinds of needs can be relatively simplified. It also takes thousands of people to maintain the thousands of acres of farm ecological greenhouses.


    In addition, there are workers around to clear the snow and build new greenhouses. After that, more and more people will be invested.


    Before the disaster, with the help of modern agricultural machinery, one person could cultivate 50-100 mu of land. Now, six talents have 20 mu of land. Even because the ecological greenhouse is a three-dimensional planting, the output is greatly improved, so it still seems that the human investment is too intensive.


    Therefore, in the view of Chen Xin and the researcher, it is necessary to consider reducing the number of people maintaining ecological greenhouses in any case.


    The reason why the ecological greenhouse needs so many people to maintain is that there are too many crops planted in it, and a lot of things need to be done every day to ensure the normal growth of all crops.


    Moreover, in order to maintain the symbiotic relationship of the ecosystem, the maturity cycle of crops is deliberately separated, so that the mature fruits and vegetables need to be harvested at intervals, which also increases the workload of daily maintenance.


    Because the ecological greenhouse over the scientific research center is for experiment, it adopts the fully automatic machinery provided by Chen Xin, which greatly reduces the investment of manpower.


    Only three to five people are needed to complete all the daily maintenance work for a 100 mu ecological greenhouse, and even harvesting does not need additional human input.


    Only the corresponding is the soaring construction cost.


    Therefore, in contrast, Chen Xin thinks that the mechanization degree of ecological greenhouses should be appropriately increased, not only to avoid the high cost of full-automatic mechanization, but also to avoid the excessive human input of full-time human maintenance.


    Properly improve the degree of mechanization, so that a person can be responsible for more work, which can not only reduce the input of manpower, but also improve the efficiency of work.


    After all, there is a problem of proficiency in human labor. There are many kinds of crops in one mu of ecological greenhouse. The maintenance workers not only need to know the crop habits, but also know the harvest time and method of each crop, which also has high requirements for the professional level of workers.


    Therefore, increasing the degree of mechanization, relying on machinery to complete part of the work that needs people to do, can not only reduce the labor intensity of people, but also better complete the work.


    Chen Xinzheng is thinking about how to improve after he goes back, but suddenly he notices that Mo Qingyan is looking out of the window with a trance and a trace of sadness.Chen Xin, who noticed this, asked her, "what''s the matter? Alone in a daze? "


    "Ah?" Hearing Chen Xin''s voice, Mo Qingyan regained her mind and quickly gave Chen Xin a smile: "it''s nothing. I just think of something."


    "Something?" Chen Xin hears Mo Qingyan say so, suddenly Leng for a while, this just reaction comes over: "is it the thing before? I remember hearing little sister Xin say that you and she used to live near the farm, right? "


    "Well, my family did live near here when I was a child." Mo Qingyan nodded, with nostalgia on her face.


    Seeing Mo Qingyan''s appearance, Chen Xin picks her eyebrows and thinks she may have said something wrong.


    After all, he clearly remembers that Mo Qingxin told him that their two sisters had a bad life when they were young. They were not only disliked by their mother, but also died early. The two sisters worked hard to get away from the home where they could not feel happy at all.


    So Mo Qingyan has lived in high school since she was a senior high school student. She has managed to earn her tuition by her own efforts. She has finally got rid of the unfortunate shadow of the past.


    As for why the two sisters are so rich, it is because when their father died, he left their land and house to them, and later they were demolished.


    After the two sisters left enough money for their mother for the rest of her life, Mo Qingyan used the rest of the money to start her own business. After a lot of hardships, she got her own business.


    Recalling these things, Chen Xin holds Mo Qingyan in her arms, saying nothing more, but comforting her with her own embrace.


    And Mo Qingyan also took advantage of Chen Xin''s arms.

 Chapter 498

    In front of the scientific research center, a transport vehicle is unloading Titan from the vehicle.


    This is the first batch of Titans returned from the disaster area. Because of the failure and the loss of spare parts, they can no longer be repaired locally, so they can only be transported back for overhaul.


    For this reason, Chen Xinhe and the researchers involved in Titan''s design and manufacture all gathered around the transporter.


    Looking at a surface full of scratches, it looks like the war damaged Titan that has been used too much has been transported from the car, Chen Xin can''t help shaking his head: "how did it get like this? Even if it''s overused, it''s not as if a Titan has been made like this! "


    For this group of Titans, Chen Xin treats them as his own works. He treats them as if they were hand-made models like Kodak.


    Now seeing that a Titan has become a war damaged version, Chen Xinxin has a kind of cherished feeling that his hands have been damaged by bear child.


    Although Titan was not made by hand, and it was not damaged by bear child, Chen Xin still felt a little bumpy when he looked at Titan with a sense of rags.


    "I''m sorry, academician, when we participated in the reconstruction work, we encountered the collapse of the building, and the two titans were buried under the ruins. It was our fault!" There were two titans in this group. The two pilots heard Chen Xin''s words and rushed to him to apologize.


    Hearing that the two titans were buried under the ruins, Chen Xin nodded slightly and asked them, "did the building collapse? What did you do with it? How did these two titans perform in this situation? What do you think is insufficient? "


    Although he was not happy that the two titans were made like this, Chen Xin didn''t let it affect him and asked the two drivers about the situation seriously.


    The two drivers looked at each other, and one of them explained to Chen Xin: "at that time, we were driving two titans to clean up the building ruins. Several ordinary workers were responsible for helping us clean up, but the building ruins collapsed again.


    When we fell down, in order to protect several workers, we covered them with Titans as supports. Bricks and stones fell on the Titans and buried the two titans, causing different degrees of damage to the two titans. "


    "The damaged parts are mainly the protective armor on the back of the Titan and the arm part. At that time, the ruins of the building pressed on the two titans, which were supported by the arms and legs, so that the workers were not crushed to death." Another driver also added, explaining the situation to Chen Xin: "because of too much weight, Titan''s arms were seriously damaged, and the back support structure was deformed.


    We didn''t have enough spare parts in the area, and some of the damage couldn''t be repaired, so we had to bring them back for repair.


    As for academician, we have talked with other drivers before about what other deficiencies you asked. We all think that the parts of the body arm are particularly worn, but the fastest consumption is the parts of the load-bearing structure. "


    "The parts of the arm are seriously worn. Are the parts of the load-bearing structure consumed the fastest?" Chen Xin heard the driver say so, clearly nodded.


    In fact, Chen Xin has predicted that the disaster relief work in the disaster area mainly requires Titan to use his arms to carry building fragments and some heavy objects. In this kind of action, the most commonly used is his arms, and the most stressed is the load-bearing structure.


    Therefore, the subsequent development of Titan engineering will naturally strengthen its arm, adjust the worn parts, and the load-bearing structure will also strengthen and upgrade the structure for the place with large loss.


    Send the two Titans back to the lab, where they will be disassembled.


    The worn-out parts sent back together with the two titans were taken for analysis and identification, so as to study the reasons why they were worn-out.


    Looking at the shell of the two titans being removed, revealing the structural parts inside, Chen Xin went to one of the Titans and observed it carefully.


    He found that most of the parts of the upper limbs of the two titans were worn and consumed more seriously than those of the lower limbs, especially some supporting auxiliary parts used to strengthen the stability of the legs, which looked as if they had not been replaced several times.


    "It seems that the stability of Titan is better than we expected. It seems that not every Titan needs auxiliary support components!" A researcher standing beside Chen Xin also noticed this.


    Chen Xin also agreed with this and affirmed: "when I was in the disaster area, I specially observed that Titan was able to stand well even on snow and ice due to the stability brought by its own weight, and there was no instability or slipping of the center of gravity caused by the humanoid structure that we were worried about at the beginning, This auxiliary support component is really not used much. ""Do you need to cancel this part for subsequent models?" After hearing Chen Xin''s words, the researchers asked him.


    Hearing this question, Chen Xin thought for a moment and then shook his head: "no, I''d better wait until the analysis results come out."


    Although Chen Xin can completely rely on the powerful functions of the system to directly cancel this auxiliary support component and adjust Titan''s structure, he does not intend to do so.


    Chen Xinzao Titan relies on the powerful functions of brain hole and system upgrade, so he can do it by patting his head or having an idea in his head.


    However, it is obviously impossible for the state to design and develop a piece of equipment like him. It requires not only step-by-step technical demonstration, but also careful consideration for every modification, and judgment can be made according to the actual situation.


    And even if it is modified, it still needs to go through various tests and verifications before it can be finally implemented on the equipment.


    If Chen Xin does everything and uses the system to solve everything, it will only make the design team lose the opportunity to exercise and eventually lose the ability of independent design. Chen Xin will be asked for everything. The consequences are very serious.


    So even if you use the system to upgrade can be very simple and direct to solve the problem, but Chen Xin still hope that these researchers through the conventional way to solve the problem.


    After all, Titan and other equipment have to go through mass production. If the research team doesn''t have the ability to deal with all kinds of problems, doesn''t know Titan itself, and has no way to solve any problems encountered in its future use, and doesn''t have the ability to develop subsequent models, it''s not a good thing for the country.

 Chapter 499

    For Titan''s follow-up improvement work, Chen Xin did not intervene, but in line with the idea of training the team to the scientific research team to be responsible for the follow-up work.


    Of course, although he did not intervene in the follow-up improvement work, Chen Xin still upgraded the original Titan drawings to the scientific research team through the system, and gave the improved design drawings of engineering, rescue and mining Titans.


    So that they can use these three drawings as a reference to provide a design idea while collecting the existing Titan usage data for analysis.


    At the same time, Chen Xin also encouraged these researchers to put forward their own ideas and ideas, not limited to the drawings he gave.


    As for the three drawings given by Chen Xin, the people in the scientific research team have long been familiar with them. Knowing Chen Xin''s "ability", no one would be surprised that he was able to take out three drawings in such a short time.


    As for the three drawings themselves, these researchers still admire Chen Xin''s talent in design.


    After all, Titan itself is Chen Xin''s design, and now there are drawings of subsequent models. In the view of scientific researchers, Chen Xin has almost taken over the task of the whole team.


    However, even convinced by Chen Xin''s talent and ability, these researchers did not copy his design completely.


    But according to the test results of the two damaged Titans and Qin Lan''s titans, we can judge where we need to improve, where we need to strengthen, and where we need to give up.


    In the final analysis, Chen Xin''s design is based on his own cognition and the result of system upgrading, which may have cognitive bias.


    For example, Chen Xin thinks that the rescue type needs to be equipped with a portable medical bag, which can treat the injured at the scene. What it should have is the role of field emergency medicine.


    However, in the view of the researchers of the scientific research team, the rescue Titan should be able to stabilize the situation of the injured in time, send them to the rear hospital for further treatment after emergency treatment, and play the function like an ambulance.


    There''s no problem with both of them. Whether it''s emergency medical or casualty transportation, both of them can be regarded as rescue Titan missions, but the focus of the two is different.


    If we focus on emergency medical treatment, the emergency Titan should have the similar ability as the medic in the game, and treat the injured at the first time on the scene.


    Although limited by modern science and technology, we can''t make the kind of medical equipment that can immediately resurrect with full blood, we should at least stabilize the situation at the scene, complete emergency treatment and preliminary treatment at the first time, and stabilize the situation of the injured.


    This is more similar to battlefield support or battlefield medical treatment. After all, Chen Xin is more influenced by game elements. In his opinion, the most important thing of rescue is to rescue and stabilize the injured at the first time.


    There are too many things in the world that can''t be rescued by the hospital. Although it can''t be completely avoided, Chen Xin still hopes to have fewer such things.


    And the researchers of the scientific research team have the right idea. Emergency treatment is really important in the rescue process, but there are also many problems in the transportation process.


    If the injured can be transported to the hospital in time for better treatment and avoid secondary injury in the process of transportation, it can also increase the survival rate of the wounded.


    However, the focus of the two is different, and the improvement of the prototype Titan is also different.


    The rescue drawings provided by Chen Xin are equipped with various medical equipment on Titan, striving to complete a series of rescue work that might have to be sent to the hospital.


    The idea put forward by the scientific research team is to increase the casualty cabin on Titan and enhance the rapid mobility of Titan, so that Titan can quickly move towards the hospital or the place where further treatment can be carried out after completing the emergency disposal of the wounded.


    As the chief designer of Titan, Chen Xin did not reject the ideas put forward by the scientific research team, but let them play freely.


    According to Chen Xin, they have different ideas, which is a good thing.


    After all, he was only a novelist before. Maybe he had more ideas than others, but his lack of professional knowledge was also obvious.


    Although Chen Xin has gained a lot of professional knowledge after becoming an academician, there is still a big gap between him and other professionals.


    Maybe he can rely on the powerful ability of the system to do things that others can spend a lot of time and energy to do, but others can also point out his shortcomings from a professional point of view.


    Therefore, Chen Xin has always been willing to accept different ideas and opinions of the team. After all, no one can guarantee that his ideas will be right. It is always good to listen to other people''s different opinions.As for Titan itself, in addition to the research and development of the three follow-up models proposed by Chen Xin, there is another research and development direction, that is, the military model.


    In fact, although Chen Xin has always said that this is construction machinery, it can not hide Titan''s military potential.


    Moreover, among the 27 Titans made before, a considerable part of them were designed for military use.


    But these Titans have not been further military transformation, they were sent to the disaster area as construction machinery to participate in disaster relief, although this has had a certain impact on the research and development of military Titans, but this work has continued.


    Chen Xin''s equipment research laboratory here is divided into two teams: military and civil. Although the two teams are not clearly divided in terms of personnel, there are still great differences in the design direction. The military type is mainly considered for military purposes.


    For example, after the Titan landed in the disaster area, the team''s researchers sent back the relevant data, and based on this, they are developing airborne and even flying models.


    However, Chen Xin did not intervene in the R & D and design work of military Titan, but completely left it to the military design team.


    It''s not that Chen Xin''s design is not good at military Titan, but his design ideas and impression of military equipment are more inclined to the game style, and he prefers cool modeling and powerful striking effect.


    This is also the best way to show this kind of large vehicle in the game.


    But in reality, there are obvious problems when this idea is applied to equipment design.


    So professional things are left to professional people. Chen Xin feels that he is still at ease to find out what is missing and provide plug-in support.

 Chapter 500

    At this time, in the distant capital of Lucia, the situation was far worse than that in Yan country, and even many places could only be described as hell on earth.


    Because of the spread of the disease, although Lucia has a relatively perfect shelter system, there is not enough manpower to run them now. There is a serious shortage of manpower in food, heating and medical treatment.


    As a result, all the refuges in the capital of Lucia are facing the difficulties of heating interruption, insufficient food supply, and the most serious patients are not treated and treated in time.


    The interruption of heating and the shortage of food supply are still temporary difficulties that can be tolerated. After all, we can tolerate the temporary difficulties in the current environment.


    However, the problems caused by the lack of timely treatment are extremely serious.


    The spread of the epidemic itself is very easy to bring panic. Even before the disaster, if an epidemic spreads in the city, even if the hospital has enough ability to treat it, it is also very easy to bring panic and fear in the crowd, leading to the rush purchase of living materials, drugs, and even riots.


    Not to mention now that the external environment is extremely bad and no one can get out of the house, being stuck in a shelter is tantamount to being put into a closed environment.


    If there are no infected people, then everyone''s mood can remain relatively stable. After all, the closed environment can also comfort the epidemic and the infected people.


    But if the infection breaks out in a closed shelter


    Have you ever seen a zombie in a zombie movie come out? In desperation, in order to find a way to live, when people are forced to the limit, they will be more terrible than zombies.


    Now, in the capital of Lucia, there are epidemic diseases in various shelters, and a considerable part of them are seriously infected.


    The speed of the spread of the disease has exceeded the official control of Lucia. Even the medical system itself has a large number of infected people. There is no way to effectively treat patients and curb the spread of the disease.


    The human resources and resources of the medical team sent by Yanguo are limited, which is even more difficult to play a role. Although some patients are treated and the doctors in Lucia are assisting in the treatment of the infected, the medical team with limited strength can only provide limited help for Lucia.


    If it''s a drop in the bucket, it won''t help much.


    They are more to ensure the health of the members of the two ark dogs and pigs, while collecting virus strains for vaccine production.


    Now the atmosphere of despair in Lucia''s capital is spreading, and there is hell everywhere.


    It''s like a powder keg that has ignited the lead. When it will explode, just see when the lead is burnt out.


    However, as Murphy''s theorem says, if there are two or more ways to do something, and one of them will lead to disaster, then someone will make this choice.


    In such an extreme situation, someone chose a more extreme way. A riot took place in a shelter in the capital of Lucia where the infection situation was not particularly serious, and swept other shelters faster than the spread of the epidemic infection, which made the situation in the capital of Lucia fall into extreme chaos.


    This can not be said to be a wrong choice. After all, under the multiple oppression of epidemic, hunger and cold, it is normal for people to choose the most extreme way to break out their emotions. However, in the current situation, it is no different from the worst choice.


    Now everything in Lucia has fallen into despair and chaos, and Lucia''s officials can only maintain the situation and not completely collapse. If we can provide effective treatment for the infected people and produce vaccines, or if we can spare more efforts to help Lucia, there is still a glimmer of hope.


    But at this time of the day, the riot will lead to the collapse of the order which can last for a period of time, which is tantamount to pushing everything into the abyss.


    If we lose order and lead everything to chaos, the fragile situation that we are still maintaining will collapse completely. If we lose the official system and medical power that are still working, we will only die of hunger and cold in disease and cold.


    No one is trying to treat infected people, no one is trying to maintain food distribution, no one is providing all kinds of security for shelters


    Everything is in disorder. People are smashing everything they see, destruction, violence, chaos. They are destroying everything that could have provided them with hope of survival.


    However, everyone fell into a frenzy, rational people tried to stop, but they were knocked down and trampled on countless feet.


    No one can stop the frenzied and turbulent crowd in the chaos, and no one can stop it.Even if Lucia''s leaders now use the army, it is only to curb the spread of the riot, and can not stop the situation from further worsening.


    After all, even the army is also infected by the epidemic. When a large number of soldiers are sick, they are also faced with a shortage of manpower.


    Unless Lucia''s leader orders the army to attack the rioting crowd, the little army Lucia can mobilize now will not be able to stop the riot.


    However, even if the rioting crowd could not break through the army, the impact of the rioting still spread, and more regions also fell into riots, which made the already stretched Lucia officials tired of coping.


    Not only that, some of the rioters also launched an impact on the direction of the medical team sent by Yanguo, intending to seize the two ark sent by Yanguo.


    Fortunately, the two ark did not land after the spread of the disease. In the face of the riot, they kept away from the ground in time, so they were not affected.


    But there are still some patients on the ark, while on the ground there are still some rescue team members from medical institutions in Lucia trapped.


    Under such circumstances, it is obviously impossible for the two ark to take off directly and leave. At least they have to rescue the trapped members of the rescue team.


    However, although the rescue team carried a certain amount of force, some of the soldiers needed to stay on the ark to protect the safety of the ark, and the other part had gone to Lucia''s medical institutions with the members of the rescue team.


    Originally they were to protect the safety of these rescue team members, but now even they are trapped on the ground.


    In the face of such a dilemma, it was impossible to ask Lucia''s official help. After discussing with the captain of the rescue team, the two ark captains sent a message of help to China.

 Chapter 501

    "What''s going on out there now?" Hu Jie asks the soldiers of Yan state who are guarding the door.


    She is a member of the rescue team sent to Lucia by Yanguo. Before, she had been working with the medical staff of Lucia to analyze the virus strains collected in a medical research institute in the capital of Lucia, hoping to make a vaccine.


    But the preparation of vaccine is a very complicated and time-consuming thing. Although the medical researchers in both countries are doing their best, the progress of research is not fast.


    So that when the riot happened, they had just finished the work of virus strain attenuation.


    This also led to them and Lucia''s medical researchers trapped in the medical research institute.


    Fortunately, this research institute was built in the suvian era, and it has good defensive ability. After Lucia''s soldiers in charge of defending this research institute closed several main entrances, the contact with the outside world was temporarily cut off, and the rioters did not break through the defensive ability in a short time.


    Although they are safe for the time being, they are actually trapped after cutting off contact with the outside world.


    People outside can''t get in, and people inside can''t get out either.


    Although there are some supplies stored in this research institution, these supplies are only enough to maintain the consumption of all people for less than a week, and will not last long.


    "It''s still very chaotic outside, and those rioters are still trying to break through our defense." Guard at the door of Yan soldiers to Hu Jie said, face a grim look, but still comfort her way: "Hu doctor, you''d better go inside, here we guard, it will be OK."


    In addition to a few Yanguo soldiers brought by the rescue team, Lucia''s soldiers are the main ones at the gate.


    Compared with the soldiers of Yanguo brought by the rescue team, Lucia has more soldiers stationed here, and they are basically doing the defense work. Because of the small number of Yanguo soldiers, they only provide some help.


    But if you look at the equipment of the two, the equipment of the soldiers of Yan country is far better than that of Lucia''s soldiers.


    Lucia was sent to protect the Institute by a special forces unit, whose soldiers were all wearing special polar winter suits.


    This is a polar combat suit that only high latitude countries like Lucia will be equipped with. It has quite good cold resistance.


    However, compared with the protective clothing and exoskeleton of Yanguo soldiers, this kind of cold suit specially used for polar combat is a time behind.


    The cold proof clothes of lucians are made of special fabrics, which can have good cold proof, waterproof and anti cutting effect to a certain extent. As a set of combat clothes, they are very good, but they are just a set of clothes.


    Compared with the protective clothing of Yanguo soldiers, which has a series of functions such as automatic heating, life monitoring, three proofs, air filtration and so on, the two just make people feel a huge gap from the appearance.


    Not to mention that the soldiers of Yan state are all equipped with the latest military exoskeleton and electromagnetic rifle.


    This kind of equipment looks like science fiction movie, but envies lucians. As soldiers, who doesn''t want to have a very reliable and cool equipment at the same time?


    However, although armed with such powerful equipment, Yanguo''s soldiers are still not sure to protect the members of the rescue team from the scientific research institute, break through the siege of the outside rioters and return to the ark.


    Even with the cooperation of lucians, they find it difficult.


    On the one hand, scientific research institutions are underground, and several major exits are also underground. Although there are no exits on the ground, the snow more than ten or twenty meters deep has already sealed the exits. It is not much easier to go from there than to fight directly.


    If you want to go out, in addition to the encirclement of the rioters, the outside is basically an underground passage, which is also a big restriction, which greatly restricts the movement of the soldiers.


    After all, the underground passage is much easier to block than the ground passage, and any obstruction can completely block it.


    So now, no matter the soldiers of Yanguo or Lucia, what they can do is to defend the Research Institute, ask for help, and then wait for the reinforcements to arrive before breaking out.


    Hu Jie naturally knew this situation. In fact, within the first time she found the rioters, Lucia''s soldiers closed the research institute with the help of the soldiers of Yan state, and sent a message for help to Lucia''s official.


    However, Lucia''s officials are now in a dilemma. The troops that can be used in the capital are short of manpower because of the epidemic. They have to mobilize troops from military bases outside the capital to enter the capital for reinforcement.And it takes time.


    According to Lucia''s official reply, the military bases outside the capital are also infected with epidemic diseases. Although reinforcements can be sent, it will take at least three to five days for the reinforcements to enter the capital, suppress the riots and rescue them.


    For those who have been trapped in scientific research institutions for such a long time, they can still persist. Although there are not many supplies in scientific research institutions, there is no problem in supporting them for three or five days.


    However, although we don''t talk about it, we are very worried about whether Lucia''s official can quell the riot, and whether reinforcements will really come in three or five days.


    If it was before the disaster, no one would worry about such a problem.


    After all, Lucia is still a big country no matter how declining she is. She is still one of the top five blue stars. A skinny camel is bigger than a horse. No matter what, it can''t be said that the hostages were trapped for three or five days without any rescue.


    But in this situation, how much power Lucia''s officials can mobilize is really a questionable question.


    Especially before, Lucia had spent a lot of manpower in the face of the epidemic infection caused by the spread of ancient virus, which led to many people becoming infected, greatly weakening the manpower available to Lucia''s official hands.


    Trapped in the research institutions are all medical staff, they know these situations very well, which naturally cast a shadow on their hearts.


    And another worry is the disease itself.


    This kind of ancient virus has been mutated to a certain extent after it spread, so that it can spread rapidly among people.


    Previously, Lucia officially ordered to block all the shelters. Although the virus spread rapidly in a certain shelter, they generally said that it blocked the spread of the virus to a certain extent.


    But now, everyone is involved in the riot, and most of the people who have the strength to participate in the riot are the only healthy people and some mild patients who are not seriously infected.


    Under such circumstances, the epidemic infection is bound to break out. At that time, even if Lucia''s officials can suppress the riot, how can the epidemic problem be solved?

 Chapter 502

    The first time the trapped rescue team members and Lucia medical researchers sent out a distress signal, Xugou and Haizhu knew about it and how they were trapped.


    As soon as they knew this, the captains of Xugou and Haizhu ark planned to organize rescue.


    After all, in addition to the rescue team personnel, all the crew members on the two ark were transferred from the Navy warships. They were professional soldiers who had received professional training and could fight with weapons.


    It is not a big problem to organize a rescue team to save people with the number of crew on the two ark.


    Only when they are ready to make a rescue plan, they find it difficult to save people.


    Although Lucia was unable to allocate enough manpower to provide assistance for the time being, she still gave great support in intelligence and information. They got the architectural drawings of the medical research institutions where the trapped people were located and the maps of the surrounding areas, as well as the riot situation shared by Lucia in real time.


    After some research, they found that if they want to save people, they have to go through several passages from underground. It is not easy to pass through countless rioters without mentioning whether the rioters will block these passages with obstacles.


    This is not a street fight in the city. There is only one underpass road. If you want to pass through a certain passageway, you have to be rigid in the front, and you can''t detour in the side.


    Although they are not without the ability of positive breakthrough, there is no way to use heavy weapons in the underground passage in order to prevent the passage from collapsing.


    Moreover, although the ark is equipped with weapons, there are no heavy weapons and weapons of mass destruction. All they can use are equipped military exoskeletons, electromagnetic rifles, and original assault rifles.


    With these weapons, if they want to kill them hard, it is not impossible, but in that case, the casualties will be too great.


    Although it is not impossible to do so, their purpose is to save people, not to suppress riots, not to kill people. Therefore, after serious discussions, they gave up the plan of killing people directly.


    "So we have to dig from the ground!" The captain of the Xugou, who had been on the ark all the time, was not infected with the same disease as the crew who went down to the ground. Now he was able to come to the pig to discuss the rescue plan.


    The captain of Haizhu nodded, affirmed what the captain said, but at the same time frowned and pointed out the difficulty: "but according to the information given by Lucia, this place was built in the suvian era, the building structure is quite strong, there is about ten or twenty meters of snow outside, and we don''t have any engineering equipment, It''s not easy to dig in! "


    "Even if it''s not easy, we have to do it. We can''t watch them trapped. We don''t do anything, do we?" The captain of Xugou is obviously more concerned about the rescue team being trapped than the captain of Haizhu. After all, the rescue team came to rescue them, which made him feel guilty and in debt. He wanted to work harder to rescue people.


    Although Lucia officials have been mobilizing troops to suppress the riot, reinforcements will arrive in about three or five days according to the progress reported by them and suppress the riot.


    But the captains of the pigs and dogs could not have hoped that the lucians would be able to suppress the riots.


    Of course, the captain of Haizhu understood this, so he nodded and said, "well, let''s gather all the soldiers equipped with exoskeletons on each ship, let them dig from the ground, and report the situation here to China, to see if China can think of other ways."


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    After receiving the information from the Hai pig and Xu dog, as well as the information from Lucia, China also paid close attention to this matter and felt it was difficult at the same time.


    Now is no more than in the past. If it is in the past, the senior officials of the Republic of Yan believe that Lucia has the ability to deal with this matter.


    Even if they can''t, it''s OK for them to send someone from home to rescue them. After all, flying to Lucia from Yan country in the past eight or nine hours is not very far away.


    But now, there are not many ways to get to Lucia quickly.


    Although Tuochen xindefu has solved the problem of aircraft flight in China, it can fly to Lucia in the night flight for nearly 10 hours without satellite navigation, or even landmarks, sky and ground as a reference. This is also a difficult and unimaginable challenge for pilots.


    This not only requires a high degree of mental concentration, but also has a huge test on the pilot''s psychological quality and endurance.


    After all, it''s dark outside and there''s nothing. Flying for nearly ten hours in such a situation, it''s easy to lose the sense of direction and judgment of the external situation. You don''t know where you are or what''s going on in front of you.Especially now the plane can not be lifted above the stratosphere, and can only fly in the troposphere. The complex weather conditions along the way are a great test of the pilots'' judgment ability and emergency handling ability.


    Therefore, although a rescue team was sent to Lucia before, it only used a slower means of transportation, such as airbags and ark, rather than a plane that can now fly again.


    There is another problem that aircraft need to consider, that is, take-off and landing. Lucia is not like Yanguo now. They don''t have runways to take off and land aircraft.


    However, it is impossible for the state to ignore this matter. It is necessary to consider how to support it.


    Under normal circumstances, the pilot may have to take the risk to try to fly to the capital of Lucia for nearly ten hours, and at the same time inform Lucia to find a way to prepare a runway for temporary take-off and landing within ten hours.


    But now there is another choice, that is to ask if the research center can come up with any effective solutions.


    After receiving the information from the senior management, Chen Xin was really surprised. Although he had imagined that there would be problems in Lucia''s side, he had never thought that there would be such problems.


    According to his assumption, Lucia''s most common situation is that the ancient virus mutates, the spread of the disease can''t be controlled, and the rescue team is trapped.


    But I didn''t imagine that Lucia, one of the top five blue stars, would also have a riot. It''s still in their capital!


    However, he was surprised, but since the senior management asked him about it, naturally he had to come up with a solution.


    In this case, Chen Xin is the only one who can come up with a solution in a short time and effectively rescue thousands of kilometers away.


    Fortunately, Chen Xin had been considering the rescue of Lucia before, but now he would not be caught off guard.

 Chapter 503

    In the open space outside the research center, a large helicopter is being towed out of the hangar by a tractor.


    The shape of this helicopter is very different from that of ordinary helicopter, because ordinary helicopter has only one propeller, while this helicopter has two huge propellers.


    Moreover, these two huge propellers are not placed on both sides or front and rear ends of the airframe like some twin propeller airplanes, but are all placed on the top of the airframe, showing an oblique cross appearance.


    This kind of helicopter is called parallel twin rotor helicopter, and only a few helicopters in the world will adopt this design.


    Its propellers are specially adjusted and designed. Although the trajectories will interfere with each other when they rotate, they will not touch each other.


    This design can improve the load and stability of the helicopter, although it will reduce the flexibility of the twin rotor helicopter.


    However, considering that it is aimed at improving the carrying capacity and stability, this is not unacceptable.


    This helicopter, of course, is not the product of Yanguo, but one of the gains Chen Xin brought back from Lucia, a prototype of a twin rotor helicopter developed in the pre suvia era.


    According to the information found, it should be the product of the same era as the V12 helicopter, which was the result of the development of heavy helicopter by suvia at that time.


    However, just as the V12 has not been put into production, this twin rotor helicopter has also been shelved and has not been put into production. There are only two prototypes found by Chen Xin.


    Two prototypes were naturally transported back by Chen Xin. One of the prototypes was handed over to the equipment research room for disassembly and research, and the other was put into the warehouse for standby after maintenance.


    When Chen Xin thought about rescuing Lucia before, he took into account the need to quickly support Lucia and transformed the spare prototype into what it is now, intending to use it as a medical transport plane.


    I didn''t expect that the original plan was just a backup, but now it''s really in use.


    There are two high-power engines on the top of the helicopter, which were originally fuel engines, but Chen Xin transformed them into the electric engines used by Yanguo at the time of upgrading, and prepared two sets of triple isotope thermoelectric batteries for each engine.


    A set of power supply, a set of standby, prepared.


    Thanks to this transformation, the maximum take-off weight of the helicopter has soared to 60 tons, while its fuselage weighs only 15 tons, making it able to take off with a maximum load of 45 tons.


    Because it was originally intended to be used as a medical transport aircraft, the internal layout of the cabin referred to the design of M26. The cockpit can accommodate six crew members, and the cargo cabin has 20 folding seats along the cargo wall. The internal space can accommodate two light infantry vehicles or two titans.


    If you don''t carry Titans, but only soldiers, the cabin of the helicopter can accommodate 80 soldiers equipped with exoskeletons.


    Now, in the cabin of the helicopter lie two lightweight specially equipped Titans, four fire enhanced heavy-duty mecha, and 40 soldiers wearing protective military exoskeletons.


    They will take the plane and fly directly to the capital of Lucia to carry out the rescue mission.


    Because it is impossible to transfer troops temporarily, the 40 soldiers on board are all special forces soldiers who used to guard the scientific research center, and they are the only ones who are most suitable for this task. After all, relying on the inherent advantages of the scientific research center, they are given to test every time new equipment is developed, and they are most familiar with these new equipment.


    "There''s only one helicopter, isn''t there a problem?" Looking at the helicopter that is nervously preparing for takeoff, Tang Tang asks Chen Xin.


    "There should be no problem. The helicopter itself is specially designed by me to be able to perform long-distance missions quickly. Considering the long flight time for long-distance missions, we also specially designed a cockpit to accommodate a crew of six, equipped with two crew members, which can rotate to avoid fatigue caused by long-time flight." Chen Xinxiang explains to Tang Tang Tang that on the one hand, it is comforting her, but on the other hand, it is enhancing his confidence: "moreover, the helicopter''s flying altitude is relatively low, so it can avoid the high-altitude airflow, so there will be no problem."


    "I hope they can successfully complete the task and get all the people back." After listening to Chen Xin''s explanation, Tang Tang nodded slightly. Then he asked Chen Xin, "for the spread of the ancient virus in Lucia, I thought you were very concerned about it. Are you worried about the spread of the virus to our country?"


    "I''m worried about this. Even if Lucia''s virus doesn''t spread, we have to prevent similar incidents in China." Chen Xin did not deny that he was worried about it.Hearing Chen Xin''s words, Tang Tang couldn''t help looking sideways. Although he felt that Chen Xin was a little worried, he should be prepared for the current situation.


    So he asked Chen Xin, "do you have any ideas? The current situation is quite different from that in the past. It''s not easy to do epidemic prevention work! "


    Chen Xin naturally agrees with this, but he is ready.


    From his pocket, he took out the health bracelet temporarily transformed from nano molecules and handed it to Tang Tang Tang. Chen Xin explained the function of this thing to her.


    "It''s really effective if you can monitor it in real time, but how can you guarantee that everyone will be willing to wear it?" Tang Tang seems to think more about this. She doesn''t think that a single bracelet can solve the problem: "what you''re saying is that we intend to use it to detect those infected with the virus, but without any disease. If the physical condition doesn''t change, how can the bracelet be detected?"


    "So this thing is only a preliminary plan, and the country may not be able to popularize it on a large scale now." In fact, Chen Xin has also considered the problems mentioned by Tang Tang. In addition to his previous understanding, he is also considering upgrading and adjusting the bracelet scheme.


    However, Tang Tang is not optimistic about the bracelet scheme. After holding up the bracelet, he shook his head and said, "no matter how low the cost of such a bracelet is, it will be a huge investment to popularize it nationwide to everyone. Even from the national level, it is not easy to do.


    And considering that the bracelet has a certain monitoring function, whether ordinary people can accept it is also a problem. If possible, I suggest Xiao Chen to think about other methods. I don''t think it''s suitable to use this bracelet. "

 Chapter 504

    Due to the slow flight speed of the helicopter and the fact that it is fully loaded, the reinforcements arrived in Lucia''s capital later than expected.


    However, this did not bring much impact. At least when they landed and learned about the situation with Xugou and Haizhu, the situation did not change significantly.


    The rescue team of trapped medical research institutions is still holding fast, the rioters have not broken through their defense, and Lucia has curbed the spread of the riot.


    Although most parts of the capital of Lucia are still in chaos, the overall situation has stabilized.


    In fact, some of the rioters have found that chaos and destruction can not solve the problem, and have begun to try to organize the rioters and re stabilize the order.


    Under such circumstances, it is undoubtedly a great benefit to the reinforcements.


    "Quick, take down the Titan!" The commander of the reinforcements yelled, urging the soldiers on the helicopter to get off the plane and unload the heavy mecha and Titan.


    This is an important firepower support and a major breakthrough means for them in this mission.


    "What are you bringing with you?" In order to meet the reinforcements, the captain of the Xu dog, who landed on the ground by airship, watched the Titan dragged down from the helicopter slowly stand up under the pilot''s operation, his eyes were straight.


    Because of the mission, Titan was still in the laboratory of the scientific research center when Xugou left Yanguo. He didn''t see it and didn''t know that the country already had this kind of thing. At first sight, he was surprised.


    "This is a lightweight and improved auxiliary unit for nuclear drive engineering, or Titan for short, which is widely used in all fields." The commander of the reinforcement force solemnly gave the full name of Titan, but he did not forget to explain to the captain of the Xu dog: "this is a new equipment that is still in the test stage, and will be mainly used for earthquake relief and engineering construction. This time, it is temporarily borrowed from us for this rescue task."


    I didn''t know that the commander of the reinforcement force was showing off in a low-key way. The commander of the dog looked at the weapons mounted on the Titan and didn''t believe it was the so-called engineering auxiliary unit.


    However, this did not prevent him from being shocked by the appearance of Titan, and he said with emotion: "is the technology progressing so fast now? Can you even make such a big guy? "


    The captain of Xugou didn''t delay his work. He adjusted his mood and discussed the rescue with the commander of the reinforcement force. The appearance of Titan greatly enhanced his confidence in successfully rescuing the members of the rescue team.


    "According to your previous plan, are you going to dig a passage through the ground?" Although the commander of the reinforcements likes to show off in a low key, it will not affect the mission.


    The captain of the Xugou definitely nodded and continued to explain: "because we were not sure when the domestic reinforcements would arrive, we deployed some personnel from the two ark to form a rescue team, landed in the airship to the trapped position of the rescue team, and dug the rescue channel from the ground.


    However, due to limited tools and insufficient manpower, we have dug more than two meters down, only about one tenth of the expected depth. It will take at least 50-60 hours to dig through. "


    "50-60 hours?" The commander of the reinforcement force touched the electromagnetic rifle in his hand, thought about it and said, "let the rescue team continue to dig. This rescue passage can be used as a backup plan and evacuation route. If our rescue is not successful, we can also let them evacuate from here."


    "Well, it''s a safe plan. How do you rescue?" The captain of the dog didn''t object to this plan. Even if the reinforcements could be rescued successfully, they really needed an evacuation route as a backup plan.


    After all, it''s totally different for the reinforcements to fight in and withdraw with people. For the sake of safety, it''s also necessary to prepare a safer evacuation route.


    "Contact Lucia, find a way for Titan to enter, we will attack directly by Titan and heavy machine armor! It''s going well. We''ll take the trapped comrades to evacuate. If there''s an accident, let the trapped comrades get out of your rescue vehicles. " The reinforcement force commander''s plan is quite simple and crude, but such a direct plan is also the most effective one in the current situation.


    After listening to the reinforcement commander''s plan, the captain of Xugou nodded after thinking about it. At this time, they could not play any tactical detour. The reason why they didn''t attack before was that they were not strong enough.


    Now that the reinforcements have arrived, they have enough strength and have the ability to break through by force. Naturally, they can choose to attack by force.


    However, before the reinforcements were ready for a strong attack, the captain of Xugou still told them: "although it is a strong attack, if it is not necessary, do not let the soldiers open fire at will, so as not to cause unnecessary casualties.""Rest assured, for this mission, we have specially brought shock bombs and tear gas. We will try our best to use non lethal force." The commander of the reinforcement force was also aware of the situation and was ready before he arrived.


    Hearing what the commander of the reinforcement force said, the captain of the dog was relieved and watched as they were ready to start the operation.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While the reinforcements were preparing for the rescue, the underground medical and scientific research institutions encountered unexpected emergencies.


    After more than ten hours of siege, the rioters gradually calmed down from the initial violence and chaos, and "elected" the leaders.


    With leaders, the rioters gradually restored some simple order and were reorganized.


    To be able to stabilize the mood of the rioters in this situation and reorganize them to restore order, the leaders of the rioters are obviously not incompetent.


    After organizing these rioters, they did not choose to continue to attack, but sent people to negotiate with medical research institutions.


    "If you are willing to treat the sick and the injured, we can provide you with food and water and keep you safe." Although the rioters'' representatives who were sent to negotiate were dirty in clothes and face, their eyes were bright. Although their attitude was not friendly, they also maintained basic politeness, which was very impressive.


    Looking at the negotiator in front of him, it seems that people can see a trace of the elegant demeanor of those ancestors who established suvia.


    However, in the face of the conditions proposed by the negotiators, the trapped rescue team members did not easily agree, but replied "need to discuss".

 Chapter 505

    "I object to their terms! The reinforcements sent from China have arrived, and they will start the rescue soon. At this time, more is better than less. We just need to stay here and wait for the rescue troops to come, and we can get out of trouble. There is really no need to cause more trouble. " One member of the rescue team took the lead in expressing opposition to the terms of negotiation proposed by the rioters.


    Although they were trapped, their contact with the outside world was not cut off. Naturally, they received the news of the arrival of the reinforcements at the first time.


    Under such circumstances, it is completely understandable that they are unwilling to accept patients and avoid causing trouble to themselves.


    After all, according to the information given by the reinforcements, they will come to the rescue within a few hours at most. If the patients are admitted at this time, there is no way to complete the treatment of the patients within a few hours.


    When the rescue troops arrive, whether the patients are taken away or left here, it will cause great trouble to the rescue.


    In the final analysis, these people are all doctors. If they are not admitted, it can be said that the conditions are not allowed. However, if they are admitted to the hospital, because of the professional ethics of doctors, they can not do such things as leaving the patients behind.


    "Although they are Lucian, we also don''t recommend treating them." Because Lucia''s medical staff are also trapped, and this is their main venue. Naturally, they also participated in the discussion, but their meaning is obviously opposite to the direction discussed by Yanguo people: "we can''t guarantee that what they send in must be harmless patients and wounded. What if this is a lie used by rioters to deceive us into opening our defense?


    What''s more, we are only a research institution, and we don''t have the ability to admit a large number of patients.


    The spread of the ancient virus has a very high infectivity, the treatment of patients need professional vacuum isolation ward, the treatment of patients also need professional medical equipment, which we do not have


    What lucians say is the fact that the main function of research institutions is scientific research rather than treatment of patients. It is very normal that they do not have the ability to treat patients.


    However, there are also people who object to this.


    "I noticed just now that many of the wounded are women and children. They should be innocent people who were injured in the riot. I think we can at least deal with the wounds for them. As for the patients..." said Hu Jie, who still hopes to do her duty as a doctor.


    Just now, when the negotiators sent by the rioters were talking with them at the door, Hu Jie saw outside and noticed that there were many injured people, many of them women and children, which undoubtedly aroused her sympathy.


    "I have no objection to helping the injured, but we are short of medical supplies. Even if we want to help, we don''t even have enough bandages and disinfectant. How can we help them?" Lucia''s people obviously have basic sympathy for their compatriots, but they really don''t have the ability to do so.


    For this problem, Hu Jie looked at the leader of Yan state.


    Noticing Hu Jie''s eyes, the team leader hesitated for a moment, and then said, "we have a repair instrument, which can treat human injury. Although it can''t treat diseases, it has a good effect on trauma or visceral injury."


    The repair instrument was handed over to the rescue team by Chen Xin together with Sanlu instrument. After they came to Lucia, they divided the equipment into two sets. One set was left on the ark for the treatment of the infected crew and the patients on the Xugou, and the other set was brought down by them.


    However, although the human body repair instrument has a good therapeutic effect on human injury, it has no effect on virus infection.


    In other words, it can only fight the virus by constantly repairing the damaged body of the infected person, which can not play a curative role, so the rescue team did not take out the repair instrument for the treatment of patients.


    "Is there anything else like that? Yan Guo''s technology is incredible Lucians obviously didn''t expect that Yan people still had such black technology.


    "I still reserve my objection. It''s too risky!" Although we now have the means of treatment, and after discussion, we also feel that it is acceptable to help the wounded, some people still reserve their objection.


    For this situation, Hu Jie thought for a moment and said: "we can ask each other to send only women and children in for treatment, and limit the number of people. That is to say, we can''t receive too many wounded at a time, let them come in batch by batch, and check the people who come in, and don''t allow them to carry weapons, so as to minimize the risk."


    "It''s a way. If we treat the wounded in batches, we can deal with them even if they have misdeeds." After discussing Hu Jie''s opinions with the person in charge of Lucia, the leader of the rescue team felt that this was a feasible plan.


    Finally, after some discussion, they agreed to treat the women and children among the rioters, but only a controlled number of them were allowed to enter the medical and scientific research institutions at a time, and they were not allowed to carry weapons.This conclusion was returned to the negotiators sent by the rioters. After discussing with some people, the other side also agreed to these conditions and sent the first batch of injured people.


    Looking at a child and a woman with a broken head and blood flow who were sent in after checking and confirming that they were not carrying weapons, the medical staff in the medical research institutions were moved with compassion.


    Although the rioters are hateful, these women and children are innocent in this riot.


    Although they may have participated in the riot and are not innocent, no one can be indifferent to the injured children.


    With the limited medical supplies on hand, the wounds of the injured were debridement, while appeasing the mood of the injured, the members of the Yanguo rescue team also took out the repair instrument, put it on the injured, and started the instrument to repair the wound of the injured.


    It has to be said that the instrument made by Chen Mo is really black technology. After the instrument is started, the wounds on the injured body begin to stop bleeding and scab at the speed visible to the naked eye. Most minor injuries are almost directly cured after treatment, and some serious injuries are also effectively treated.


    Soon, the injuries of the first batch of injured people were basically dealt with.


    Hu Jie sent the wounded after treatment out of the medical and scientific research institutions, and noticed that the negotiators of the rioters were always standing at the door. The look in his eyes at the wounded showed his sincere concern.


    "Thank you for your willingness to help these people. I''ll arrange for food and water for you." The negotiator noticed Hu Jie''s eyes and gave her a friendly smile.

 Chapter 506

    With an explosion, the roadblocks set by the rioters were opened again, and the pace of the reinforcements was still unstoppable.


    In fact, it''s too hard for a group of ordinary rioters to stop the combination of Titan and heavy mecha.


    The Titan and heavy mecha, which are all made of steel, are just like the main battle tank. Even on the battlefield, they can only be destroyed by heavy firepower.


    Even though Lucia''s rioters used the traditional skills of roadblocks and Molotov cocktails, they didn''t do much harm to the Titans and heavy mecha of the reinforcements.


    What they are facing is not a tank with inconvenient steering. It is impossible for them to burn the radiator of the tank''s engine with Molotov cocktail.


    For heavy mecha, Molotov cocktails may burn the driver in it for a while.


    But at the front of the team are two titans specially adjusted for this mission. Although they are light-weight in order to install helicopters, they are also equipped with enough shields to cover the front of the whole Titan in order to cover the rapid advance of their comrades behind in the underground passage.


    Although Molotov cocktail is a civil anti tank artifact, it can be smashed on a smooth shield. It has nothing to do with it except adding a layer of flame effect to the shield.


    The two titans pushed away all kinds of obstacles in front of them with their shields, opened the passage, and at the same time directly deflected the shields to aim at the opening.


    Sure enough, two Molotov cocktails were smashed directly, which ignited the gap just opened and ignited the flames all over the ground.


    This is not the first time that the reinforcements have encountered such a situation. They delay their actions through obstacles. After they break the obstacles, they throw Molotov cocktails. They have encountered the same routine too many times, which is about to make the two Titan drivers form conditional reflection.


    Two titans next to the heavy machine armour is also very direct in accordance with the previous experience step forward, arm equipped with grenade launchers fired directly at the gap.


    After a huge explosion and flash, the two titans continued to push the obstacles, while the four heavy mecha went through the gap and continued to move forward with the following soldiers.


    As for the rioters rolling on the ground with their eyes and ears covered, they were too lazy to deal with them. There were too many rioters on the way. Lucia''s army, which had been cooperating with them, had already captured the prisoners and had no bandages.


    Fortunately, they just threw it on the ground. Anyway, they were just flashed by the shock bomb, and they didn''t get any fatal injuries. They could get up even if they lay on the ground for a while.


    "How far is it?" The commander of the reinforcement force saw that with the cooperation of Titan and heavy mecha, he passed another obstacle and nodded slightly. While he was satisfied with Titan''s breakthrough ability, he was more concerned about the mission.


    The soldier next to him quickly took out the map provided by Lucia. After looking at it, he pointed to the exposed passage behind the obstacle and said, "through this passage, there is only one intersection left."


    "Let the comrades move faster and try to reach the target before the rioters create new obstacles." The commander gave a new order to the soldier beside him. He was really annoyed by the obstacles along the way.


    If he didn''t keep in mind that he was a soldier of the Republic of Korea and that he was not a federal army that could hurt civilians at will, he wanted to order the heavy machine armour to be replaced with grenades and went all the way.


    It has to be said that sometimes they are envious of the federal army. At least they can use lethal weapons against ordinary civilians without shame and scruples. Even if they cause casualties, they can say a word of accidental injury.


    But the soldiers of Yan state can''t do it. Even in the present eschatological environment, the state and high-level officials also default to use heavy allusions in troubled times, but as soldiers, they still have to abide by the most basic code of conduct as soldiers of Yan state, and can''t use lethal weapons against ordinary civilians, even if they are rioters.


    It''s not pedantic. It''s just that as an army, the soldiers of Yan state never kill innocent people like the federal army.


    Throwing away the little unnecessary emotion in Kaixin, the commander asked his soldiers to move forward quickly. They were not far from the medical research institution where the rescue team was trapped. He hoped to finish the task quickly.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "That army broke through too fast! We have set up seven obstacles, all of which have been broken through by them. Now they are only the last intersection from here! Vasili, we can''t stop them A man with a bloody forehead and a handkerchief was shouting to the negotiator who had been negotiating with the rescue team.The negotiator, known as Vasili, was almost wringing his brows. Of course, he guessed that the army which had been breaking through towards them was to rescue the people in the medical and scientific research institutions trapped by them, but he had to organize his own people to stop each other in a nearly futile way.


    Although an agreement has been reached with the people trapped in the medical research institutions to help treat the injured and provide them with food and water, it is impossible for him to release the army.


    In any case, they were rioters, enemies of Lucia''s authorities, and the army, of course, was their enemy.


    It''s one thing to negotiate with the trapped hostages to treat their own wounded, but it''s another to let the enemy go.


    Vassily is very clear about this kind of thing.


    Although the beginning of the riot had little to do with Vassili and his companions, they just stood up to organize the rioters and rebuild order after the riot began to spread. In a sense, they should be the pacifiers of the riot.


    But in Lucia''s official view, they are still part of the mob camp.


    But for Vasili and his companions, they would like to call themselves revolutionaries like those who overthrew tsarist Russia and founded suvia a hundred years ago.


    They are all young people born after the disintegration of suvia. They have not experienced the beauty of the suvia era, but they have experienced the darkest period of Lucia. They have heard from their parents and grandparents about the beauty of the suvia era.


    This makes these young people yearn for the former suvia. They think that all the sufferings of Lucia are due to the disintegration of suvia, and lucians have lost their original red faith.


    They want to rekindle the fire of revolution in Lucia''s land and let the red flag fly again!


    They believe that they can do what our ancestors could do 100 years ago, and by that time, Lucia will be able to get rid of her present suffering.

 Chapter 507

    To rebuild the red country is a wonderful ideal for lucians.


    Once the era of the red Empire, but also Lucia''s most brilliant era.


    Although they have had such brilliant monarchs as Peter the great and Catherine the great, and Alexander I, who has been full of legends all his life, there is no doubt that the most brilliant era in Lucia''s history is still known as the world''s two poles of the suvian era.


    In that era of bipolar hegemony, the red flag was a threat to the whole world, not only its enemies, but also its allies.


    This may be due to the desire for conquest and the desire for warm land in the bones of lucians. Since the era of Peter the great, Lucia has been a country full of desire for expansion.


    Ekaterina the Great wanted the whole of Europe to crawl under his feet. Alexander I defeated Napoleon. Even Nicholas II, the last czar, was still actively expanding when the whole country was struggling at home and abroad, and his rule was crumbling, In the first World War


    This has to make the whole world full of vigilance to this Lucia roller, not to mention how aggressive the original red empire was.


    So the dead suvia is the good suvia. The red empire is only suitable to be buried in tombs and engraved on monuments for people to remember and remember. Anyone who wants to rebuild it will become the enemy of the whole world.


    And this is the same for Yan state.


    No one wants to have a strong neighbor by his side, and this neighbor has come to your house to beat, smash, rob, bully you, and want to turn you into a neighbor of my younger brother.


    So Vasili and his companions are destined to choose an impossible path.


    Only Lucia before the disaster, of course.


    After the impact of the meteorite, it may be suffering for the whole world, but for Vassili and his companions, it is a good opportunity.


    Because they feel that suffering can awaken the people of Lucia, let them recall the lofty aspirations and ideals of their ancestors when they cut through the thorns to build a country, rather than drowning in despair in the ruins and ashes after the collapse of the red empire.


    But although suffering has come, but for Lucia did not let them wake up.


    Today''s Lucia has no real greats, and Vassili and his companions are not the revolutionary doers who dared to rob banks for their ideals.


    For a time, Vasili and his companions felt hopeless, that the country had no hope, that their great "revolutionary" ideal would not be realized, and that the country would die of hunger and cold.


    But the riot gave them a "great" chance, a chance to realize their "ideal".


    So they stood up, organized the disorderly and chaotic rioters, stabilized the disorderly order as much as possible, restrained the rioters, and intended to overthrow the present official Lucia on the basis of these rioters, and then establish their dream of new Sudan.


    Originally, everything went well. They succeeded in gaining the approval of most of the rioters, organizing them and controlling the situation.


    After all, they are all young people with "ideals". In addition, when discussing ideals, they are always very fierce, and their eloquence is very good. Although they can''t respond to each other, it''s OK to call on some rioters to listen to their own words.


    In addition, they have more or less certain ability, and have made some plans for realizing their "ideal". The progress at the beginning is really going as they expected.


    If there is no accident, it is possible for them to realize their "ideal" and rebuild suvia.


    However, everything is afraid of a "but", the reinforcements sent by Yanguo to rescue the trapped rescue team become the existence of lifting the table.


    Of course, this force is not to suppress the riot, but the front line of the rioters is unimpeded by the other side, which is absolutely unacceptable to the rioters.


    This will affect not only the leadership of Vasili and their opponents, but also the overall situation in the capital of Lucia.


    After all, the lines that the reinforcement troops of the Republic of Korea have penetrated can be a breakthrough for Lucia''s army to suppress the riots.


    Under such circumstances, even if vasilimin knew that he would release the trapped people in the medical research institutions, the army would leave, and he could not do so.


    If you do that, the rioters who are organized to listen to him will collapse.As a matter of fact, Vasili''s subordinates are already a little unstable. They have failed to organize defense for several times in a row, and a large number of people have been injured and captured. These rioters, who were originally scattered and barely gathered together, have already had a lot of opinions on Vasili.


    If no one can replace him, I''m afraid Vassili has been ousted at the moment.


    "Don''t let them pass! No matter what method you use, you must stop them! " Vassily clenched his teeth, and the rioters under his hand gave orders to die.


    Although he wanted to organize an effective defense, or bravely block the enemy with his flesh and blood as those great patriots did in the patriotic war, it was a pity that Vasili''s men were just a group of rioters organized temporarily, not the revolutionaries who experienced the test of blood and fire in those years.


    If they were the revolutionaries of those years, they would be able to stop the enemy with their flesh and blood, and win with their sacrifice and blood.


    However, it is almost impossible for these rioters and a group of young idealists with "ideals" who want ideals but no ideals, will but no will, and even lack of organization, to block an army with a generation gap in science and technology.


    Perhaps after giving them the opportunity to pass the test and exercise, these rioters and young idealists will turn into firm revolutionaries.


    But unfortunately, they are not.


    So even though Vasili has issued a death order, the rioters have tried their best to set up obstacles. What they can bring to the reinforcements is only a very limited delay.


    No matter how "solid" the defense can not stop the progress of Titan and heavy mecha. The team organized by the rioters who lack the support of ideals and beliefs is just a castle piled up with sand, which can be kicked down with one foot.


    "We are soldiers of the burning state. We are here to rescue you." The reinforcements, after breaking through the rioters'' last line of defense and making them retreat like a tide, said to Lucia, a soldier at a medical research facility.

 Chapter 508

    The arrival of reinforcements immediately solved the dilemma of medical research institutions.


    The originally besieged rioters have all withdrawn, leaving only some obstacles they had built nearby.


    However, these things are not much better than paper paste for reinforcements with two titans.


    As a result, after the reinforcements cleared away the rubbish at the entrance of the medical research institutions, the rescue team that had been trapped could leave with them.


    In the opinion of the commander of the reinforcement force, the task is simpler than expected.


    Of course, this is mainly due to their Titans and heavy machine armour. Otherwise, it is very difficult for ordinary soldiers to break through the obstacles set by the rioters.


    At least, the accumulated obstacles are not things that can be easily broken by human force in a short time.


    But with Titan, those obstacles, they directly use Titan to push or tear down brute force, which can''t be an obstacle at all.


    Even after seeing the actual effect of Titan, the commander thought that if it was urban street fighting, it would be better to have such a big guy than a tank.


    This also made the commander''s eyes on the two titans more intense.


    Despite the commander''s obsession with the two titans, the people trapped in the medical research institutions began to prepare to leave after the reinforcements arrived.


    Only those who are ready to leave with the reinforcements are the trapped members of the Yanguo rescue team, while Lucia''s medical researchers say they will stay and continue to develop vaccines against the epidemic.


    "Sorry, we can''t leave. It''s our job and task. We have to finish it." An elderly woman in Lucia''s medical researchers gave a smile to Hu Jie, who suggested that they leave together. She said seriously: "as a doctor, I can''t watch a disease ravage and be indifferent. As a Lucian, I can''t watch my motherland suffer and do nothing. If it''s doomed, I can''t leave here, Let this be my last time to protect my motherland and my people. "


    Looking at this woman, Hu Jie found that although both sides have worked together for a long time, it''s still her "this is something I got before. I''ll give it to you as a souvenir." With that, the woman hugged Hu Jie again.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    The rescue team followed the reinforcements and all the lucians stayed.


    Yan people did not persuade them to leave, after all, everyone has their own responsibilities and tasks.


    Although the people of the rescue team also want to stay to help develop the vaccine, the country has sent troops to rescue them, and there are riots outside. In this case, it is not a suitable choice to stay.


    Maybe it''s really important to develop vaccines, but it''s not only irresponsible for us to stay in the current situation, but also to live up to our country''s efforts of sending troops from afar to rescue them.


    So although they wanted to stay and help the lucians develop the vaccine, the rescue team finally took a sample of the virus strain and left with the reinforcements.


    However, before they left, they pushed back the obstacles that had been cleared, and sealed the entrance of the medical and scientific research institutions from the outside, so as to prevent the rioters from coming back here again and causing unnecessary trouble to Lucia.


    Although it''s not very safe, it can at least help the people in it stick to it for a long time.


    And the commander of the reinforcement force also told the lucians that they had dug a passage from the ground. Although the passage had not been dug through, there was still at least two-thirds of the depth. Although the Yan people would not continue to dig, it was not too difficult for the lucians to dig the passage themselves.


    On the way back, the reinforcements were ready to fight again, but I don''t know if it was the rioters who knew they couldn''t stop them, or they thought the rescue team had already come out. It was unnecessary to stop them again, or they were afraid of being beaten before. In short, no one stopped them.


    The reinforcements and rescue team were able to leave the underground of Lucia capital and return to the two ark.


    However, because the reinforcements and rescue teams came back from the epidemic area, they all need to be isolated and observed for the time being. After all, even if they wear fully enclosed protective clothing, there is no guarantee that they are not infected with the virus.


    So for a while, even if the state has decided to withdraw people, they will not be able to leave for the time being.


    Although it''s not impossible to isolate them when they return home, this is also the idea of these people. They don''t want to take the virus back, at least before the vaccine is developed.And back on the ark, Hu Jie went back to her room, and then she took out the red book and the medal that the old Lucian woman gave her and looked at it carefully.


    This is the highest medal awarded in the era of suvia at that time to reward and commend those individuals, collectives, organs, social organizations and troops who have made outstanding contributions to socialist construction and national defense.


    The old Lucia woman in the red book was awarded the medal for her outstanding contribution to the treatment of the wounded in the cheetown incident.


    She has defended her country and people once, and now for the second time.

 Chapter 509

    "... OK, I see. Let''s borrow the two titans first, and then I''ll let the maintenance engineer live with the spare parts." Chen Xin is talking on the phone in the communication room of the scientific research center.


    Hearing Chen Xin''s reply, he seems to have said something, but Chen Xin sticks the receiver to his ear, so that other people can''t hear what he said except him.


    "Vaccine development? I might be able to help with the production, but the research and development work... "Hearing that the person on the phone mentioned the vaccine, Chen Xin still knew something about it, and some didn''t quite understand what the other person meant by saying:" is there anything I can help with? "


    Vaccine research and development and production are two completely different fields. The research and development work is to find harmless viruses that can stimulate the human immune system, but will not cause damage or little impact on the human body.


    And production is to produce this kind of harmless virus isolated from the laboratory on a large scale, and then use it in actual medical treatment.


    In principle, there is nothing particularly high-tech about the R & D work itself. It is nothing more than the isolation of virus strains, then inactivation and attenuation.


    Although new technologies will be applied to the separation, inactivation and detoxification procedures in the medical field, the main purpose is to improve the efficiency of vaccine research and development and the efficacy of the final vaccine.


    If we ignore these two points, we can achieve the same result even if we use the laboratory of the general medical college and let the medical students operate.


    However, this time will be very long, and the efficacy of the vaccine can not be guaranteed.


    It''s like a pool of cards. Ordinary medical students are like the zero krypton party. They carry bricks every day to save a little stone, and then they just gamble on their faces to smoke pools without a minimum.


    Although the face of the basic black are heavy, but it can not be denied that some of the blush can only draw out a miracle.


    Professional medical laboratories, like the krypton gold party, can use krypton gold to get more stones. At the same time, they can also use the krypton gold at a discount and with a guaranteed bottom, with a special pool for up.


    Even if the face is not good, it may be crooked or sunk, the kryptonists still have the last way, and they can get it directly after drawing a certain number of times.


    Therefore, in a sense, to deal with a virus, vaccines can be developed in most cases, which is nothing more than the problem of R & D cycle.


    As for smallpox, rabies, tetanus and HIV, they belong to the case that the pool is too deep for discussion.


    Chen Xin''s role in this is to increase the up and delivery probability of the pool, reduce the minimum number of times, and make a discount, so that you can use fewer stones and times to achieve the purpose of delivery.


    Although there is not any place to help, in fact, there are still limited places to help.


    And in terms of modern medical technology, it can only be regarded as icing on the cake, and it has little effect on actual production.


    Because factory production and laboratory research and development are two different ways, laboratory is short, flat, fast, and factory production is cheap, accurate, stable.


    So, to achieve the same goal, laboratories like to use simple and efficient methods, and when it comes to production scale, these methods will be abandoned.


    For example, for the simplest solid-liquid separation, the laboratory must want to use membrane filtration for the first time. The specific point is the beginning of disposable membrane filtration, and then the high-end point is membrane chromatography, so small things, money is not a problem!


    But these technologies don''t talk about production, and they can''t go on in the pilot scale. It''s hard to scale up! What should I do?


    It''s cheap, stable and easy to use. Cipsip is not a problem.


    In this case, Chen Xin''s ability can play a greater role. He can upgrade the equipment of the factory to make them more advanced and efficient.


    However, the person on the phone with Chen Xin obviously considered these problems and said something to him before Chen Xin agreed and hung up.


    Seeing Chen Xin Hang up the phone, Tang Tang, who had been standing beside him and looking at him, asked, "what does it mean? Would you like to help develop a vaccine? "


    "No, it''s the rescue team." Chen Xin shook his head and then explained to Tang Tang: "they have been in the epidemic area before, so they can''t come back now, but they want to continue to develop vaccines, but they lack equipment.


    I hope that we can provide them with a set of simple equipment that can be used, and ask if there is any good way for us, otherwise we can only air transport instruments and equipment from China, which is too troublesome and expensive. "


    After listening to Chen Xin''s explanation, Tang Tang could understand it, but she still asked strangely, "why don''t they use Lucia''s equipment? They''re going to help Lucia. Lucians don''t even want to borrow a set of equipment, do they"The situation in the capital of Lucia is very chaotic now. Although they dispatched troops to suppress it, the situation has not improved. The rioters blocked the underground passage and confronted Lucia officials." Chen Xin told Tang Tang the latest information he had just obtained from the phone: "without using heavy weapons, Lucia''s military has no good way to solve the problem in a short time, so the situation is very bad now.


    For the sake of safety, the rescue team has withdrawn from the underground city of the capital of Lucia and stayed on the two ark, temporarily unable to use the equipment and Laboratory of Lucia


    "The situation is really bad enough..." Tang Tang also felt a little speechless about it. He was one of the top five blue stars. As a result, he couldn''t even suppress the riots in his capital. He really didn''t know what to say.


    But strictly speaking, these things have nothing to do with them, so Chen Xin quickly took a picture of Tang Tang Tang and said with a smile, "well, we don''t need to consider these things. Elder sister, you help me to transfer a batch of equipment, and the task explained above still needs to be completed."


    "OK, I see." Tang Tang nodded. Having been in the Research Center for so long, she also understood Chen Xin''s "ability" and knew how to cooperate with him: "are you going to improve a set of equipment and send it to him?"


    "It''s more convenient for them to use it by integrating it into an experimental shelter. It''s also troublesome for them to find a test site to send a set of equipment to them." After thinking about it, Chen Xin thought it was not convenient to upgrade a set of equipment and decided to build an integrated experimental shelter.


    After hearing Chen Xin''s words, Tang Tang just raised his eyebrows. Although he was a little surprised, he was used to it: "OK, I''ll arrange it."

 Chapter 510

    At this time, the situation in the capital of Lucia has been moving towards the worst, as irreparable as a derailed train.


    Stimulated by the destruction of their defense lines by the reinforcements of the Republic of Korea, the rioters in the capital of Lucia clearly realized the gap between themselves and the regular army, so they greatly strengthened their original defenses and obstacles, and further consolidated their sphere of influence.


    This undoubtedly brought great trouble to the Lucian army with no black technology equipment such as Titan and heavy mecha.


    Although Lucia''s official troops entered the underground city of Lucia''s capital, launched attacks on the rioters and recovered some areas, they did not achieve much in suppressing the riot itself.


    Lucia''s army was unable to destroy the rioters'' defense line as quickly as the Japanese army, so the government and the rioters fell into a state of confrontation.


    The official Army was unable to break through quickly, and the rioters were also unable to attack.


    After a few days of chaos and destruction, these rioters have been completely incorporated and organized by Vasili and his companions.


    Although the army of the Republic of Yan broke through their several lines of defense before, which made the rioters dissatisfied with Vasili and his companions to a great extent, and made a small number of rioters leave them and no longer obey their orders, there were still a large number of rioters under their command, which were incorporated and organized by them.


    These people think that the general situation has become, and the rioters must have formal organizations and names. So they named the incorporated rioters the revolutionary army and themselves the Revolutionary Committee, and gave everyone a title of committee member.


    However, none of the members of the so-called revolutionary committee really understood what revolution was and how to do it.


    Most of them have only read a few books describing the suvian era, and have not even read the real revolutionary thought works. They are just doing their so-called "revolutionary" work with their illusions and so-called revolutionary ideals about the suvian era.


    It''s just a simple copy of some organizations and appellations of the suvian era, one-sided copy of some forms of that era, and in the real management, it''s just a little better than the disorder before.


    Of course, although there are some problems and hidden dangers, there are no problems in general.


    True revolutionaries certainly need the guidance of revolutionary thought, but that is only guidance.


    A real revolution needs to decide exactly what to do according to the actual situation, rather than copying mechanically or applying experience and regulations.


    Although Vassili and his companions have no experience, no one is born with such experience. They now have the foundation and advantages of success. As long as they can seize the opportunity, it is possible for them to realize their ideal "revolution".


    In this process, after all kinds of tests and hones, Vasili and his companions may also be able to become real revolutionaries and understand what is a real revolution, just like those revolutionary ancestors who founded suvia.


    But only if they can seize the opportunity.


    Although they were just a group of idealists at the beginning, they were able to seize the opportunity, stand up in the riot and organize the rioters, which is enough to show that they still have enough executive power, at least they did seize the opportunity.


    But this is just the beginning. They have to face all kinds of problems.


    They did occupy most of the capital of Lucia, and even blocked the attack and repression of the official Army, turning the situation into a confrontation, but this does not mean that everything is OK.


    It''s true that they occupied the site, but without the official coordination and management, they also lost the resources imported from the official control area.


    These resources include the fuel and food they need most in the current situation, as well as the most important medicines.


    After all, it''s not the past. Even though lucians can''t bear the extremely cold environment, they have to face food shortage and epidemic.


    If the rioters had not been too disappointed with Lucia''s official position before, and had a certain degree of trust and support for the so-called revolutionary committee in a short period of time, and they had indeed improved some order and temporarily stabilized their rule in the current situation, I am afraid they would be the next to be overturned.


    Although the situation is optimistic for the so-called revolutionary committee at present, the people''s patience is sometimes very limited. Once they can''t make the situation better or make the people lose their expectations, they will soon be overthrown.


    Especially for the so-called revolutionary committees, they have not even mastered the most basic force.They are not the revolutionaries who founded suvia at the beginning. They have a leader with steel will who can obtain revolutionary funds by robbing banks and have channels to purchase weapons.


    Most of these so-called revolutionary commissars are just young people with empty ideals. Although they have enthusiasm and certain executive power and are willing to do something, they still have no real consciousness of struggle and sacrifice, and they do not understand that martial arts are the foundation of everything.


    Now they only block the official Army by setting up obstacles. In fact, they lack weapons, military training and systematic struggle strategies.


    If all this can''t be improved, as long as the official Army of Lucia finds a way to break through the obstacles, the so-called revolutionary achievements they have built up now will be destroyed soon.


    As a matter of fact, it is not that Lucia officials have no way to break through the obstacles.


    For maozi, never doubt the possibility that they want to do something, and their ability to find the simplest and most crude way to achieve it all.


    For example, they dare to use hydrogen bombs to blow up a reservoir, and they dare to use nuclear weapons to put out the oil field fire.


    At present, they just don''t want to use some destructive means in their own capital. Moreover, the Titan used by the Yanguo people before made lucians feel that the effect is very good. They are looking for Yanguo people to discuss how to use Titan to remove obstacles. For a while, they will not use heavy weapons to take destructive means.


    Because of this, the time left for Vasili and his companions was running out. Once the result of Lucia''s official search for Yanguo to borrow Titans came to fruition, the army would certainly launch another attack. The so-called revolutionary army and revolutionary committee could not resist the attack of the official army without military support.


    As for the matter of borrowing Titan itself, whether we can borrow it or not has no influence on the result.


    It''s nothing more than Titan''s demolition of obstacles, so that Lucia''s military can not use destructive means.

 Chapter 511

    As for Lucia''s official intention to use Titan to break down the obstacles set by the rioters, the high-level officials of Yanguo agreed after a simple discussion.


    On the one hand, it''s not a big thing. It''s just borrowing a piece of equipment. Although Titan''s technology is classified as a state secret, if it''s only borrowed, it won''t cause leakage.


    What''s more, borrowing or not actually has little influence on Lucia''s official suppression of the riot. It''s just a little easier suppression or a suppression that will destroy everything.


    On the other hand, the high-level consideration of Yan state is also the main reason why they agreed to lend Titan out of consideration of the relationship between the two countries. After all, Lucia''s officials have been dealing with Yan state for many years, and both sides know the root and the bottom.


    It can be said that the high-level exchanges between the two countries have been going on since the time of suvia. Over the years, both sides know each other and know how to communicate with each other.


    However, if there is a new leadership, Yanguo must re measure the relationship between the two countries and the cooperation with each other, and at the same time, there are many things such as whether the agreements reached before can continue to be implemented.


    Even before the disaster, this is not an easy job to complete.


    After all, great power diplomacy itself is a very complex matter. Every move may involve all aspects, even if a leader is careless and says a wrong word, it may lead to diplomatic events or even war.


    What''s more, the high-level officials of Yanguo don''t think that Lucia can''t even suppress a riot, even though Lucia is at its weakest moment.


    In the final analysis, they are just a group of rioters. They have no military guarantee, no experience of struggle, and even no external interference.


    Under such circumstances, if a group of rioters can successfully overthrow the official rule of one of the top five blue stars, then Lucia''s official is a bit too humiliating.


    However, although Lucia''s official borrowed Titans from Yanguo successfully, the two titans have not been put into use for a while.


    As a matter of fact, Titan, like all other vehicles, relies heavily on logistics.


    In the past, because it was only intended to be used once in the rescue operation, and the things were sent back after the mission was completed, Titan was directly loaded into the helicopter and transported here, without any logistics maintenance.


    Originally, there was no problem. No matter how Titan ate logistics, it was not exaggeration to say that it would be overhauled once.


    However, the previous rescue operation still caused some losses to Titan, which needs logistics maintenance.


    After all, the official crackdown in Lucia will obviously have a high-intensity use of Titan. In order to avoid problems, the logistics department must repair and maintain Titan before it can be safely put into use.


    Of course, it goes without saying that the logistics department is responsible for the maintenance of Titan and the collection of Titan usage data.


    Lucia also began to actively prepare for the next crackdown after getting the exact reply from Yanguo. She planned to solve the problem once Titan was ready.


    While Lucia officials were seriously preparing for the crackdown, the members of the "Revolutionary Committee" were also discussing this matter fiercely among the "revolutionary army" to be suppressed.


    "We should negotiate with the authorities! Discuss terms with them! " One of the young men, who looked a little frail, was frantically trying to convince others: "the government has the army, and our revolutionary army doesn''t even have decent weapons! If the army attacks, we can''t resist it at all! "


    What wenwenwennan said is the truth. Although they organized the rioters, reorganized them into the so-called revolutionary army, and carried out military training with great enthusiasm, it can''t cover up the fact that they can''t even have a gun.


    They are not even as good as the Frenchmen in the first World War. At least the Frenchmen can hold a gun and a bullet. They can only share a gun with five or six people, and they don''t have many bullets.


    However, in addition to the weak men, although other people also expressed concern about this, it was more of a blind self-confidence.


    "Don''t worry about wa Lianjing. Even if our comrades don''t have weapons, they won''t be afraid of those capitalists!" A woman with a warm and proud face persuades the weak man, WA Lianjing, and her words are widely accepted by others around her.


    "Dalia''s right! We are revolutionaries! We are destined to beat those rulers Some people applauded loudly and clapped at the same time, which made the atmosphere of the meeting very warm.


    But this did not convince wa Lianjing. He still looked grim, and his face was very anxious: "but we can''t let our comrades resist the bullets with their flesh and blood! Do you want them to block the army''s machine guns with their bodies? ""Why not? In the Great Patriotic War, did our ancestors block the German attack with flesh and blood Another "committee member" said, but no matter his attitude or tone, he was a bit frivolous.


    Although the "committee member" is speaking for Dalia, she obviously does not like the saying: "no, we are responsible for the lives of our comrades! Although wa Lianjing''s worries are pessimistic, they are still reasonable. We can''t let our comrades make fearless sacrifices! "


    "Then we''ll send someone to negotiate! We can settle it peacefully! " Walianjing heard Dalia say so, immediately revealed a trace of joy, excited to persuade her.


    "No, walianjing! We don''t negotiate! " Dalia shakes her head and rejects walianjing''s proposal: "revolution through tyranny! It is impossible for the revolution to succeed without bloodshed and only relying on the compromise of the rulers! We must resist resolutely! "


    At this point, Dalia raised her hand to stop walianjing who wanted to say something else. She looked at Vasili and asked him, "Vasili, you are the only one among us who has fought against the army before. Tell me your opinion!"


    Dalia''s eyes to Vassily are full of encouragement. They are very good friends. Vassily was also a man full of energy before, but his previous failure made him decadent. Dalia has been trying to encourage him to cheer up.


    "To be honest, we can''t stop it." Vassily shook his head helplessly, and recalled in his mind that the black steel giant easily pushed aside the obstacles, ignored the burning flame, and appeared in front of him like a demon: "before, the military used a terrible steel giant, I don''t know why they didn''t continue to use it, but once it was put into battle, It''s hard for us to resist even if we have weapons. "

 Chapter 512

    Vasili''s attitude undoubtedly made Vasili feel that he had found a supporter. He said hastily: "that must be the secret weapon of the military! Think about my friends back then! Suvia is one of the two poles in the world, the only superpower in the world. How many powerful weapons have we studied!


    The official Army must have inherited those great research and weapons, and used these weapons that should have been used to defend our country on its people. They want to suppress us with those powerful weapons! Put out the fire of revolution!


    We can''t just sit and die! We should find a way to preserve the fire of the revolution, so that we can have the hope of a successful revolution! "


    Walianjing looked very excited. He was always pessimistic about the resistance of the "revolutionary army" to the attack of the official Army.


    This is why he always wanted to persuade people to negotiate with the official. He felt that the "revolutionary army" could not defeat the official Army. Only through negotiation could they get the hope of survival and not be suppressed and exterminated by the official.


    But it is clear that the words of wa Lianjing did not convince others, and even angered a group of people who were blindly optimistic.


    "Walianjing! You revolutionary speculator! How much benefit have you received from the government to shake the morale of the army here? We are revolutionaries. Revolutionaries are invincible! We are destined to win the revolution and rebuild the great suvia! " One of the committee members cried out, looking very angry, and almost pointed to Vassily''s nose.


    However, WA Lianjing did not care about this. Although he was pale and had an abnormal flush, he still tried hard to persuade these people in front of him: "no, comrades, the revolution is doomed to victory, but in the process of victory, we have to go through twists and turns and tribulations!


    In the era of tsarist Russia, how many tests did our ancestors go through before they won the great victory and overthrew tsarist Russia? After the overthrow of tsarist Russia, how many tribulations did we go through to make suvia the greatest country in the world?


    Even so, the great suvia still fell under the enemy''s plot, we can''t be blindly optimistic! Only by negotiating with the government can we avoid being suppressed and save the fire of the revolution! Even the great iron and steel comrades of those years had peace talks with moustache? "


    "You bloody traitor!" The people who quarreled with wa Lianjing saw that they could not win with words, so they simply chose to solve the problem with physical means.


    However, before he swung his fist, he was stopped by Dalia: "stop! All the people in this room are comrades and comrades in arms! There are no traitors among us! Take back what you said and apologize to wa Lianjing! "


    "Dalia!" The person who quarrels with wa Lianjing looks at Dalia angrily. Obviously, she is still angry and doesn''t want to apologize.


    But Dalia''s attitude is very firm, and finally the other side is reluctant to say an apology.


    Although she pressed the other party to apologize, it did not mean that Dalia supported walianjing. She turned to walianjing and said to him, "walianjing, I know what you mean. You are also good for the revolution, but we don''t negotiate. The revolution needs blood and sacrifice. We can''t win by compromise."


    At this point, Dalia looked around at all the people and said to them seriously: "we have come to the present for the reconstruction of the great suvia. Although we will have different ideas and quarrels, we must unite, because only by uniting can we win, and it is because of uniting that the original suvia can achieve greatness!


    The enemies we are going to face are really strong, but they will not be stronger than the enemies our predecessors faced! Our ancestors can defeat the enemy by unity and faith, and we can do the same! Comrades, we must unite


    Dalia''s words are full of appeal. Although some people still disapprove of them, they all agree on the surface.


    They reached an agreement. Although there was no result in the discussion, at least everyone''s emotions were aroused. Dalia assigned some tasks and then announced the end of the meeting.


    The committee members in the room gradually dispersed, leaving only a few key members to hold another meeting.


    Although they don''t understand Dalia, they also understand that too many people can''t discuss anything.


    "Vasili, how is the construction of the defense line going?" Dalia first asked Vassily about it.


    Although the defense line he built before was the same as the paper one, among so many people in the Revolutionary Committee, Vassili was the only professional who studied civil engineering. Dalia asked him to take charge of this matter not only because of selfishness.


    Vassili shook his head and said in a low mood: "I''ve strengthened the defense line as much as possible. At present, it''s still effective. At least the official Army has stopped attacking. But I''m not sure whether these things can resist the previous steel giants.""It''s good that it can work. As for the steel giant, I don''t think even the official secret weapons can be used casually. We''ll be ready." Dalia encouraged Vassily as much as she could. She hoped her friends would cheer up as soon as possible.


    "Dalia, the problem now is not just to resist the enemy''s attack. We are running out of fuel for food and heating. We must find a way to replenish it." Another person raised another issue that they are facing now.


    If the official attack belongs to foreign aggression, then the shortage of materials belongs to internal worries.


    "It''s really a big problem. We don''t have many greenhouses in our control area. What we consume now is the previous reserves. We must find a way to obtain new food sources." Dalia also knows the importance of this matter, these days she has been trying to find a way: "there is a large official greenhouse outside the city, if we can control it, we can get new food supplies, we can try to send someone to take it!"


    "But it''s not easy to win there. We''ve sent someone to see it before. With our current strength, it will cost us a lot to win there." The speaker just now expressed his worry. Although the revolutionary army does not say that there is no force in hand, to be honest, it is enough to maintain public order. If there is a real war, it will not be of any use.


    "If you have to pay, you have to fight! And not only the greenhouses, but also the coal mines in the suburbs. Only by taking these places can we guarantee the supply of materials, and we can... "Dalia was talking seriously, but suddenly someone pushed the door in and interrupted Dalia''s speech with a look of panic.


    "No! Something''s wrong The face that rushes in can''t hide the panic, shouts to Dalia and others.

 Chapter 513

    There''s something wrong.


    Moreover, it is a great event that the "revolutionary army" can not handle at all.


    It has been said before that the initial rioters were due to the spread of the epidemic, and a large number of people fell ill in the shelter. However, Lucia''s official did not properly handle this matter, which led to the outbreak of the riots.


    But after the riots, the problem of the spread of the disease has not been solved.


    On the contrary, because of the riots, a large number of people came out of the originally closed shelters, resulting in the spread of the disease, but in a short period of time created a large number of infected people.


    Originally, the Revolutionary Committee intended to deal with the epidemic after the situation had stabilized.


    They just isolated the infected people and sent a few doctors to do what they can to control the situation.


    At first, it seems that there is no problem, but the virus will mutate.


    In fact, as long as the virus proliferates, its genome is mutated all the time, most of which are lethal, and only a few can survive.


    But in the process of a virus infection, it needs to proliferate millions of times, which naturally has the chance of mutation.


    Usually, the mutation of viruses will only be more adapted to the environment, but occasionally it will become very dangerous, such as lethality, air gel, droplet transmission and so on.


    Although the possibility is very low, there is still a virus mutation in theory, making people as aggressive as zombies.


    In fact, this situation is not without, for example, the well-known rabies, after infection, due to the attack of the nervous system, people will show certain manic, irritable and aggressive.


    Of course, this is only a possibility, and the mutated virus only makes the living people very aggressive. It''s against biology to expect that the dead body can still move and have simple intelligence, just like in the movie.


    As for the standard configuration of zombie novels such as high-speed evolution and instant self-healing, as well as such things as motivation and brain stones, it only exists in imagination.


    The problem that the "revolutionary army" encountered was that some of the infected people suddenly became manic, full of aggression, and even began to bite others.


    This kind of zombie movie scares all people and makes most of the infected people panic. They can''t tell whether it''s rabies or zombie virus. For a moment, everyone thinks it''s Zombie infection.


    So they collapsed in an instant.


    Everyone is screaming to get out of the quarantine area, and even the severely infected, who are unable to move because of the virus, are struggling to stay away from those who have become zombies.


    But they wanted to escape, and the people outside the quarantine did not dare to let them out.


    I''m kidding. Behind them are those guys who are as violent as zombies. Who can guarantee that these infected people have no problem?


    So for a moment, the gate of the isolation zone became a line of life and death. Outside the gate was life, inside the gate was the hell of death.


    Fortunately, although the incident happened suddenly, we have to say that there are still several reliable people under the Revolutionary Committee. They informed the Committee at the first time, and Dalia, Vassili and other leading members of the Committee arrived at the scene at the first time.


    Looking at this tragic situation, Dalia naturally wanted to release the infected person in it for the first time.


    But her decision was stopped.


    "Can''t let it out! They''ve become zombies. Let them out and we''ll all die! " Several of Lucia''s strong men with weapons were full of fear on their faces. Although they had guns in their hands, their legs were shaking at the moment.


    Even though Lucia''s men are not afraid, even brown bears dare to slap her in the face, zombies are different.


    Thanks to the popularity of zombie movies in recent years, everyone knows that this thing can be infected. If it is bitten, it will become the same thing, so no one dares to open the door.


    Even though Dalia has always been very authoritative, no one wants to listen to this order at this time.


    In particular, the constant screams in the isolation area make everyone unwilling to open the door to isolate life and death.


    But someone rushed up, ready to open the door.


    "What are you doing! You can''t open the door Two strong men guarding at the door pointed their guns at Vasili who was opening the door.


    However, Vasili didn''t look at the muzzle of the gun pointing at his head at all, but said calmly: "these people are still alive now, even zombies can''t stop the bullets. If we don''t take advantage of less infected people to control the situation, we can''t control them when there are more and more infected people!And don''t forget, the virus can be spread through the air. If it can be infected, you will be infected. It''s not something that can be infected just by a bite! "


    Although the two strong men who were frightened by Vassili''s words had been pointing a gun at Vassili''s head, they never pulled the trigger.


    Until he really opened the door and released the infected person who wanted to escape, the gun did not ring.


    Vassili and the two strong men, as well as all the people standing at the door, all rushed out of the way to avoid being scattered by the surging crowd.


    However, the infected people who escaped from the sky didn''t go far. The isolation area is a refuge area. The gate they were in just now is connected to the underground passage behind them, and the underground passage has been blocked by the people who were called by Vassili.


    Although these infected people escaped from the isolation area and were not bitten by the zombies inside, they were still restricted and isolated at this moment.


    Vassily didn''t take care of the escaped people. Instead, he grabbed a gun from the strong man beside him. He directly aimed at a guy with a bloody mouth and a ferocious face who rushed out of the isolation area. He didn''t hesitate to pull the trigger.


    The bullet was very effective. It went straight through the head of the infected man with his mouth full of blood.


    At the same time, Dalia grabbed another gun and stood with Vasili. The two guns sounded together, with more blood on her face, showing that the violent infected person was knocked down.


    Watching Vasili and Dalia successfully knock down these "zombies" with the blessing of "taking the lead in charge", the people who were originally sent to guard the zombies finally summoned up the courage to follow them and enter the isolation area together.


    "Tie up the undead of these ''zombies'' and carry them away. They are likely to have virus mutation. We need to let professionals have a look." Vassili thought of the doctors who had helped treat the wounded, and thought they might know what was going on.

 Chapter 514

    "What about them?" Looking at the doctor wearing heavy chemical protective clothing to check the "zombie" still alive, Vasili asked with great concern.


    After the incident, the older woman in Vasili shook her head as she spoke, apparently feeling very difficult about the mutation of the virus.


    Dalia listened to the feelings of the older women, and did not care about the mutation of the virus, but just asked her: "can they still be saved?"


    "In terms of our medical conditions, it''s hopeless." Older women didn''t mind Dalia''s attitude, but shook their heads helplessly: "nervous system damage is the most difficult to treat, which is why rabies has a 100% mortality rate. Once infected, there is almost no way to cure it."


    "Do all these people have to die?" Vassily felt a numbness in his scalp. It was not just that these people would die.


    The virus has become diseased and has begun to spread. No one can guarantee that only these people are infected by the mutated virus, especially before they were locked in the isolation area with other infected people. If other infected people are also infected by the mutated virus, many people will die.


    Vasili''s memory is not bad enough to forget how the riots happened before. If such a large number of infected people die, their "revolutionary army" will become a joke and will soon be overthrown again by the angry people.


    So in any case, we can not let the infected people die on a large scale, let alone let them become "zombies"!


    "In theory, it is so, but if..." the elderly woman thought of the body repair instrument used by the Yanguo rescue team before, and said with some uncertainty: "I have seen an instrument that can repair the human body, which may be able to repair their nervous system damage. As for eliminating the virus and infection, you can pray that our vaccine can be made as soon as possible."


    Although she thinks it''s not good to drag Yanguo people into the water, she really can''t watch her people die like this, and she doesn''t want to see the city she once built and lived in become a zombie siege. So the older woman still tells us what she saw before.


    "Is it the kind of instrument that used to heal the wounded?" Vasili still remembers this. Although he was later hanged by titans of the reinforcement forces of the inflammatory state, so that all his mind was captured by Titans, he also remembers that the wounded who were sent here for treatment almost recovered in a short time.


    The older woman nodded and said, "it''s just that kind of instrument, but it''s a pity that it has been taken away by the rescue team of Yanguo. It''s their thing. Otherwise, you can try to use that kind of instrument to repair the nervous system, although I''m not sure whether Yanguo people''s things can repair the nerves."


    When they heard this, Dalia and Vasili didn''t say much. They didn''t care about the instruments of Yanguo people, but more about how they should deal with the matter in front of them.


    "What should we do with the wounded? There are also many infected people who were isolated with them before. What measures should we take for them? " Dalia asked the older woman.


    "Of course, the best way is to send it to the hospital for treatment, but now we have no good treatment for the infection caused by this virus. We can only let the patient''s body heal itself through supportive therapy." The older woman sighed helplessly, but she was more dissatisfied with Dalia and Vassili: "it turns out that we can still rely on the official allocation of medical resources to research vaccines and treat patients, but your so-called" revolution "ruined all this!


    Without order and official deployment, and lack of resources and supply, we can neither continue to study vaccines nor treat patients! They have to wait to die now! If you are kind, you can make them go less painful. "


    Hearing this, both Vassily and Dalia''s face suddenly changed, and they became very unwilling.


    But Vasili''s reluctance comes from his inability to save these people, while Dalia is unwilling to slander their "revolution" by older women, but can''t refute each other''s words.


    The older women seem to see their attitude. Maybe they are in sympathy with the patients, or they feel that there are still people in pursuit of the so-called "revolution" in this era. She said to the two young people, "if you want to save these people, you can go to peace talks with the authorities and treat the patients first in a humanitarian spirit.


    As for your so-called "revolution", if you want to really engage in revolution, at least go to see revolutionary works and enrich your thoughts. Let''s talk about revolution again! If you just blindly imitate the former suvia, then what you can get is nothing more than the outcome of our past! "


    "Revolutionary works? Does that really work? What should we look at? " Dalia looked at the older woman in front of her, and seemed to think that her age should have experienced the suvia era. She was willing to listen to her words.After all, for these young people who yearn for suvia, they have not really experienced that era, and there are not many works of that era to read in modern times, which makes them really lack the corresponding theoretical knowledge.


    "Go and look for it. There should be libraries in the urban area. You can read all the books of that era on revolutionary process, experience and theory." At this time, the older women seem to have changed their attitude towards Dalia, telling her the titles of a series of revolutionary works in the suvian era.

    "When Vassili and I went to a professional research institution, the experts there suggested that we should make peace with the government and solve the epidemic together. What do you think of that?" Dahlia saw that no one else seemed to have any good ideas except the one she couldn''t possibly adopt, so she said what she had discussed with Vassily and was also asking for other people''s opinions.


    At Dalia''s words, there was a buzz in the hall, and everyone could not help discussing the matter.


    When walianjing proposed the negotiation before, most people opposed it, and no one even supported him clearly, because at that time, everyone felt there was no need to negotiate with Lucia.


    They are revolutionaries and are destined to overthrow each other. Of course, they have nothing to talk about with the enemy.


    But now, faced with an unsolvable dilemma, these people naturally have no so-called revolutionaries'' insistence, and they are very concerned about negotiating with the officials.


    However, before this time, WA Lianjing, who had been persuading everyone to negotiate with the official, stood up and said in a loud voice: "I am against direct negotiation with the official! So we are too passive! In that case, we are surrendering to them! We should wait for the official to take the initiative to negotiate with us! "


    "Wa Lianjing, what''s the matter with you? It was you who had always said to negotiate before, but now Dalia said to negotiate, and you jumped out to oppose it. What do you mean? " As soon as wa Lianjing''s words were finished, the people who quarreled with him last time jumped out again. I can''t stand the attitude of wa Lianjing.


    However, WA Lianjing knew what he was talking about. He ignored the people who jumped out and said directly to Dalia: "Dalia, before I hoped to negotiate with the official, it was because we couldn''t win. We were at a disadvantage. In that case, if we hit hard, we could only be exterminated by the official.


    Fortunately, we still have a certain strength, and the official can''t break through our defense for a while and a half, so we take the initiative to show our sincerity and desire for peace talks, so that we can preserve the fruits of the revolution.


    But the current situation is different. We need to seek help from the government. In this case, if we act too urgently and carefully, we will be suppressed by the government. We will be in a passive position in the negotiation. That will be too bad for us! "


    After his words, WA Lianjing looks at Dalia with burning eyes. He hopes Dalia can agree with him. After all, in his opinion, what he proposes is for the sake of revolution.


    Dalia listened to what wa Lianjing said and fell into thinking.


    If it was before, she might not listen to walianjing, and she would feel that he was too pessimistic and not loyal enough to the revolution.


    However, in the current situation, the so-called revolutionary army has fallen into a rather unfavorable situation and declining trend, especially after Dalia was educated by the elderly woman, her thoughts have also been changed to a certain extent. At this time, she has to admit that what wa Lianjing said is very reasonable.


    However, although she thought that what wa Lianjing said was very reasonable, Dalia had to admit another thing in her heart, that is, neither wa Lianjing nor she was a real revolutionary, or a pure revolutionary.


    They lack the spirit of revolutionary struggle, otherwise they would not be entangled in this issue at all.


    If they are real revolutionaries, they will not shrink back and compromise no matter what kind of hopelessness they face. They may fail and give way for a while, but their inner beliefs are always pure and firm, and they will go on unswervingly in order to realize their own ideals and beliefs.


    But Dalia and walien Kyoto are not such people, or there is no such revolutionary in their so-called revolutionary committee.


    At first, they were just a group of young people who were dissatisfied with Lucia''s present life and found out the beauty of the suvia era from the old paper pile in the past.


    The so-called revolution is just a kind of imagination of them. They imagine that they can start a revolution like their predecessors, so they call themselves revolutionaries.


    But in the final analysis, they just think that if they start a revolution, they can rebuild suvia and make life as beautiful as described in books. As for how to start a revolution and what to do after a revolution to make life better, they didn''t think about it at the beginning.


    That''s why they are so naive now that the so-called revolution has begun.


    Although they managed to control the situation by imitating some things of the suvian era, and some of them were talented, which enabled the so-called revolutionary committee to operate, it was just a fragile existence. A sudden crisis could completely destroy everything they had established.Now that the crisis has occurred, the so-called revolutionary army they have built is in danger.


    But now Dalia has realized her own problems. When she makes a decision, she will start to think about her shortcomings and make progress.


    If everything goes well, with such continuous progress, Dalia may really grow into a qualified revolutionary and leader.


    But only if she does have the opportunity and the time.

 Chapter 516

    Anton is a special forces of Lucia, originally stationed in an important border military base in the European part of Lucia.


    When the meteorite hit, Lucia completely reduced her strength. Most of Asia was no man''s land, but it was nothing. She just had to withdraw the population and the people from some secret military bases.


    In addition to some very important functional military bases, many military bases used only for garrison have been abandoned, and these soldiers have also been withdrawn around the capital.


    For this reason, Anton returned to Lucia''s capital with his troops.


    His family has also been living in shelters in the capital since he served in the army, instead of staying in the small town of his hometown.


    However, Anton now regrets that he brought his family to the capital, because the previous riots made him feel that the capital was too unsafe, especially now there is an epidemic.


    Thinking of this, Anton can''t help pressing the mask on his face, as if it can make him feel more secure.


    "Damn it, the logistics doesn''t send two sets of anti chemical clothes, only masks can do anything!" Anton could not help but curse.


    His current position is the front line facing the rioters. For the sake of epidemic prevention, the higher authorities have provided each of them with epidemic prevention equipment and a bag of masks.


    This makes Anton really want to greet the female relatives of his superior family. After all, the global epidemic only happened before the impact of the meteorite. We all have a little understanding of how to defend against the epidemic, so we don''t know that the epidemic is spreading without wearing masks.


    It is because of this kind of cognition that Anton knows how dangerous the epidemic he is facing. At this time, he wants a set of full body closed protective clothing that he used to wear during chemical defense exercises.


    That thing can bring him a sense of security. Although this mask is not useless, it really makes Anton feel uncomfortable.


    Just as Anton complains, behind the obstacles piled up by the rioters in front of him, several rioters remove some obstacles used to block and clear a narrow passage.


    Vasili stood in the passage and looked at the guard post set up by the opposite army, where Anton, wearing a mask, stood.


    "It''s the sentry of the official Army. It seems that there are only two or three people. It''s safe." Vassily looked around and saw that there were only two soldiers dressed the same as Anton. Then he said to Dalia behind him, "give me the white cloth and I''ll negotiate."


    "Vassili!" Dalia grabs Vassily''s arm. She''s worried that Vassily will go out to negotiate.


    After all, the current situation is that they are really unable to deal with the epidemic.


    If they do not negotiate with the authorities, they will soon be unable to maintain the banner of the revolutionary army.


    Under such circumstances, negotiating with the government and using the power of the government to stop the spread of the epidemic and mutated virus is their only choice now.


    Although they will go to negotiate with the official, the decision made by the Revolutionary Committee is to reach an agreement with the official only on the prevention and control of epidemic diseases. Apart from that, they will not talk about any other issues.


    The negotiator they elected was not walianjing who had always wanted to negotiate, but Vasili who offered himself.


    "Don''t worry, Dalia. I''m going to negotiate. The authorities don''t want to say that we are not given this opportunity to have a dialogue." Vasili comforted Dalia and felt what she was ready for. She felt that the possibility of successful negotiation was very high.


    After all, what the mutated virus means is so terrible that Vasili believes that the authorities can''t be indifferent or play tricks on such things.


    When someone opened the barrier, Vasili stretched out the white cloth Dalia had given him and shook it. Seeing that the soldiers on the opposite side noticed, Vasili slowly walked out of the barrier holding the white cloth.


    "Hey! I''m here to negotiate! Don''t shoot Vasili yells at Anton, trying to hold up the white cloth to show that he is here to negotiate.


    Anton naturally noticed Vassili, and the white cloth was still very conspicuous.


    In the face of this situation, Anton doesn''t know how to deal with it, but he reacts very quickly. Although he raises his gun, he doesn''t aim at Vassily. He just yells at him: "stay there! Keep your distance


    After shouting, Anton said to the two soldiers beside him, "go and call an officer! It needs to be dealt with by officers! "


    With that, Anton turns his head to Vassily and shouts to him, "I''ll ask someone who can talk to you to tell you, stay there!"Vassily was relieved to hear Anton say so. He nodded at him and cried, "OK, I won''t move. Please hurry up!"


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    What the rioters wanted to negotiate was quickly reported to Lucia''s leaders, which was a relief to Lucia''s leaders who were worried about the riot.


    After all, the riot has seriously shaken Lucia''s current stability. As a leader, he does not want his country to be broken, especially he has experienced the pain of his country''s breaking.


    As a member of the former red country, Lucia''s current leader clearly knows how much suffering it brought to the people of Lucia after the collapse of the red country. He also knows that if the rioters really overthrow Lucia''s current official, it will only make the country fall into the abyss.


    Those rioters will not understand the serious consequences of Lucia''s loss of order.


    It is with such an idea that as the leader of Lucia, he would not hesitate to offer the suvian heritage to Yan country in exchange for the opportunity of assistance and cooperation, in order to help Lucia in today''s predicament and not collapse.


    He also plans to directly mobilize the army to use violent suppression to end the riot, in order to avoid more damage to Lucia caused by the riot.


    Now we have received the news that the rioters want to negotiate, which makes Lucia''s leaders very relieved. This is a better result. Although there may be some hidden dangers and troubles, at least we don''t have to kill in our own capital.


    Thinking of this, he cheered up and was ready to deal with the negotiations with the rioters himself.

 Chapter 517

    "Lucians want to negotiate with the rioters? What''s going on? Didn''t they prepare for violent repression before? " The two captains of the ship are gathering to discuss this issue.


    "According to the information provided by Lucia, it should be the rioters who can''t hold on. There is a virus mutation in the area under their control. The infected people will become as aggressive as zombies. They are scared." The captain of the Haizhu explained to the captain of the Xugou, and put a piece of information in front of each other, which was a picture of the "zombie".


    Looking at the ferocious "zombie" in the picture, with his mouth torn and his face covered with bloodstain, even the captain of Xugou had experienced many battles, had a lot of knowledge and was startled.


    He picked up the photo, looked at the captain of the pig in surprise, and asked, "is this real? It''s not an April Fool''s Day joke, is it? Don''t foreigners like April Fool''s day, Halloween or something? Are they kidding at the festival


    It''s not that the captain of the dog didn''t believe it, but that this kind of thing was too amazing for him to accept.


    However, the captain of the Hai pig shook his head and replied in the affirmative: "it''s true. In order to enhance their persuasion, the rioters who call themselves" revolutionary army "also provided Lucia with a living" zombie ".


    In addition, these "zombies" are alive. They have been eroded by the mutated virus into the nervous system, so they become full of aggression. It doesn''t mean that they really become the kind of zombies in the movies. "


    "Isn''t it just like rabies?" The captain of the dog was relieved. The zombie in the movie was too dangerous.


    But as long as it''s not that horrible thing, it won''t make him feel too much pressure if it''s just a rabid patient.


    After all, today''s military has Titan and heavy machine armour, which will not have any pressure even if they meet the zombies in the movie. As long as they are willing to use bullets, they can still suppress the siege of zombies.


    However, the captain of the Hai pig splashed cold water and said, "don''t think about it. This mutant virus is also highly infectious. According to the information provided by Lucia, although there is no evidence that this mutant virus can be transmitted by air, it can be transmitted by droplets just like the original virus, It''s also very dangerous


    "What shall we do now? Have you reported the matter to China? " After the captain of the dog calmed down, he immediately thought of reporting to the mainland.


    "The relevant information has been reported to China, and there are no new instructions in China at present. Let''s hold still and do a good job in epidemic prevention and vigilance." The captain of Haizhu was also having a headache about this, so he asked the captain of Xugou to discuss: "do you think we should withdraw all the people on the ground and let the ark rise to a safe height?"


    At present, the high speed of the two ark is a relatively low mooring height. If necessary, they can rise to a height of one or two kilometers to maintain a distance from the ground.


    There are still some people on the ground. They are mainly the former reinforcements, who are responsible for maintaining the helicopter that sent Titan and guarding the materials on the ground.


    It''s not that the captains of the two ark were unkind, and people came all the way to save people and left them on the ground. It''s Titan and heavy mecha. It''s very troublesome to transport such equipment to the ark. It''s very difficult to operate at the mooring height if it''s transported by airship.


    In addition, considering the fact that Lucia''s officials wanted to use Titan to suppress the riot, they didn''t transport Titan and heavy mecha to the ark before, but set up a simple camp under the ark to place Titan and heavy mecha, as well as the soldiers of the reinforcement troops below.


    Now, if we want to raise the ark, we must consider withdrawing the people. After all, it is not convenient to send people down to reinforce the ark when it is tens of meters high. If it is one or two kilometers high, it is not convenient to transport supplies.


    "It''s better to maintain the current height for the time being. In the current situation of Lucia, it doesn''t threaten us." The captain of the dog shook his head. Although Lucia''s condition is very bad now, it''s not enough for the ark to rise to an altitude of one or two kilometers.


    The ark has three heights: a mooring height of about 50 meters from the ground, a hovering height of about 300 meters, and a safe navigation height of more than 1000 meters.


    Under normal circumstances, the Ark will remain at the hovering height or mooring height, and will rise to a safe height only when in danger or moving.


    "Although there''s no threat, it''s better to be vigilant. I think we should at least rise to hover height." The captain of the hog still thinks it''s safe.


    After thinking for a moment, the captain of Xugou nodded and said, "in this case, raise the altitude to 300, and the people on the ground will not withdraw for the time being. Let''s send two airships down to prepare them for quick evacuation if necessary.""Well, that''s OK. It''s safe." The captain of the hog agreed.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While the captains of the hog and dog discussed how to deal with the problem of Lucia''s capital, they also received news from them at home.


    The news of the virus mutation has obviously shocked China. According to the information shared by Lucia, this is only a virus that will corrode the nervous system of the infected person and make it aggressive. It is not a kind of terrorist biochemical weapon that can revive the corpse and stand up again, but it still makes China very nervous about this.


    The high level held an emergency meeting to discuss how to deal with the matter. At the same time, they also asked various domestic research institutions whether they had any way to deal with the situation.


    However, most of the scientific research institutions have obviously not encountered this situation, and what they give is nothing more than some suggestions on epidemic prevention.


    Only Chen Xin''s scientific research center, because of Chen Xin''s black technology, has put forward some different suggestions.


    "To deal with zombies, we can make soldiers wear power armor or protective clothing with enhanced defense. Anyway, they are only living people who have been infected, and their killing power is limited by teeth. It''s no problem to do a good job in epidemic prevention." In the face of the high-level inquiry, Chen Xin was indifferent: "as for vaccine and treatment, it needs professional medical experts to deal with it. What I can help solve is the need of medical equipment. I had the idea of making a medical cabin before, and maybe it can be used in this aspect."


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 518

    The apron of the research center was cleaned up and a huge flying vehicle was pushed out.


    The reason why it is called a flying vehicle is that it looks more like an aircraft than an airplane or a helicopter.


    There are no wings on both sides of the aircraft and no propellers on the top. Instead, four plasma jet engines are installed at the tail, which are suspended by two cantilevers that can change angles.


    Now the four engines are facing the ground. After the aircraft is loaded, they will provide enough thrust to make the aircraft take off more like a car than an aircraft, and then adjust the cantilever angle to enable the four engines to jet backward and make the aircraft fly forward.


    This is a new model improved by Chen Xin on the basis of the previous medical transport plane. It has larger internal space, can carry more things, and also has faster speed.


    In addition, the aircraft is not much different from the previous medical transport aircraft, except that the cockpit is opened, the cabin is divided into upper and lower layers, and the lower layer is still used for transporting materials.


    On the upper deck, Chen Xin installed a newly made medical cabin.


    It''s different from the medical cabin in science fiction, but it''s not the kind that infuses a lot of nutrient solution to soak people in, but some medical cabin that can automatically detect their physical condition and carry out treatment when lying on it, which is similar to that in blissful space.


    Of course, Chen''s new version of the medical cabin can''t be as exaggerated as the one in "blissful space" where half a face is blown up and can be repaired, but there is no problem in treating some human injuries.


    For example, the nerve damage caused by Lucia''s mutant virus can be cured with this instrument.


    As for the principle of treatment, it is the same as the repair instrument Chen Xin gave to the rescue team, which stimulates human regeneration through a special kind of radiation.


    However, the stimulation effect of this kind of radiation is limited. In addition, the human body itself can not do such exaggerated things as limb regeneration or limb regeneration, so the function of the medical cabin itself is limited.


    But this is only compared with the medical cabin in science fiction. If you just look at this medical cabin, it can treat many diseases.


    It is precisely because of this medical cabin that Chen Xin dares to say that he has a way to deal with Lucia''s affairs.


    After all, even if this version of the medical cabin can''t treat those infected, it can be upgraded directly to be cured.


    In addition, there is a simple small medical laboratory on the transport plane, which can be used for vaccine research.


    In fact, the medical cabin is placed in the medical laboratory. After all, the space of the transport plane is limited. Even if Chen Xin divides it into the upper and lower layers, it is very difficult to accommodate a small medical laboratory and medical cabin.


    The newly completed medical transport plane will fly directly to the capital of Lucia after loading a team of experts in materials and viruses.


    At this time, the expert team temporarily dispatched by the state has started boarding. Only when they get on the plane and put their personal belongings away, they notice that there is a person in the cabin who should not be here.


    "Academician Chen? What are you doing here? Are you going to Lucia in person A medical expert had met Chen Xin before, and when he saw him on the plane, he immediately showed a surprised expression: "it''s too dangerous. If you go in person, we can''t bear the responsibility in case of infection!"


    "Don''t worry. I''ll go with you. I''ve got permission from the top." Chen Xinchong, a medical expert, laughed for a while and then explained to him: "there is a simple laboratory I installed on the plane, in which there is a state-of-the-art medical cabin. That instrument can treat all kinds of human injuries, including nerve injuries.


    But this instrument is only an experimental model. No one except me understands its specific situation. If something goes wrong, only I will repair it, so I have to go with it. Of course, one of my assistants will also come with me. "


    "But this..." after hearing Chen Xin''s explanation, the medical experts were surprised at the appearance of the medical cabin, but they were more surprised that Chen Xin would go to the epidemic area with him.


    After all, they have been informed that the epidemic area is very dangerous, and there have been zombie type infections and mutated viruses, which makes all members of the expert team very nervous.


    As experts in this field, they are a group of people who know the harm of the virus best, and know how harmful the mutated virus will be if it spreads.


    In this case, it is no doubt dangerous to go to the epidemic area.


    As a matter of fact, even before they came, they all came on a voluntary basis, and they all signed a life and death certificate and wrote a suicide note.So they instinctively do not want other people to take such risks, especially researchers like Chen Xin.


    In the view of this medical expert, Chen Xin is undoubtedly a very powerful researcher who can develop such an instrument as the medical cabin. In particular, he said that only he knows the specific situation of the medical cabin, let alone let him risk his life.


    It''s just that the medical expert has something more to say. The rest of the expert team also got on the aircraft one after another. The team leader came over and shook hands with Chen Xin.


    "Academician Chen, I already know what you are going to do together." The team leader held Chen Xin''s hand. Although he looked easygoing, his attitude was very serious: "although I don''t object to your going together, I hope that after arriving at Lucia, academician Chen, you can stay in a safe place and don''t enter the epidemic area.


    This time, the virus is very terrible and dangerous. We don''t know about this virus at present. Although the samples we brought back were analyzed, we still don''t know enough about it and there is no good treatment at present.


    In this case, if you are infected, the consequences will be very serious, so I hope you can always stay in a safe place, so as to minimize your risk of infection. "


    The leader said so, but there was no doubt in his eyes when he looked at Chen Xin.


    Although he agreed to go to Lucia''s capital with Chen Xin, the team leader also knew the importance of Chen Xin and obviously could not let him enter the dangerous area where he might be infected.


    Chen Xin naturally won''t have any willful and reckless action in this kind of thing. He nodded his head and said: "you are experts in virus, you are the boss."


    "OK, I hope we can complete the task successfully this time." When the team leader heard Chen Xin say this, he was relieved and laughed at him. Then he sat down in the cabin.


    Chen Xin saw everyone on the plane and said to the pilot in the cockpit, "take off! Let''s go

    The efficiency of the new aircraft is comparable to that of the helicopter''s "slow" vehicle.


    In fact, for the first time after they flew, the new aircraft''s flight speed became subsonic.


    If not for the body bearing capacity of the members of the aircraft, the maximum flight speed of the aircraft can directly exceed the speed of sound.


    Of course, if you do that, except for the driver wearing anti-G suit, other people''s bodies must bear a great G force, but something will happen.


    However, even so, subsonic flight speed, or make the aircraft in a few hours across thousands of kilometers, arrived in the capital of Lucia.


    "The dog and the pig have been found and are in contact with them." The pilot''s report came from the cockpit, and soon gave a new feedback: "they have built a temporary landing site on the ground, I see the light signal."


    As the pilot''s voice dropped, Chen xinmingxian felt that the speed of the aircraft had dropped, and he switched from the original high-speed flight to the low-speed hovering for landing.


    A few minutes later, the aircraft had landed on the ground.


    "It seems that the landing method needs to be improved. It''s a bit bumpy." Chen Xin looked at a cup of water beside his seat and recorded this.


    After all, it''s a new aircraft. Although there is no problem in every aspect literally, some details are a little rough. For example, the bumps during landing will make the passengers in the aircraft feel uncomfortable.


    If this kind of aircraft is only for military use, there is no need to consider the comfort of this aspect. After all, military aircraft is not for civilian use, so it doesn''t matter if the comfort is poor.


    However, if the aircraft is used for medical rescue, it is necessary to consider this point, because the aircraft may be loaded with the seriously injured, and the bumping will cause the injury to be aggravated.


    However, these are all the details that need to be dealt with after going back. Chen Xin did not take care of these problems when he recorded them. Next, his focus is on the prevention and control of the virus that Lucia is spreading.


    Although the prevention and control work is mainly in the charge of the expert team, Chen Xin is not responsible for specific affairs, but he can improve the equipment and equipment to be used, so that it can better defend against virus invasion, and provide great help for the treatment of patients.


    The leader of the expert group naturally knew this, so he agreed that Chen Xin would come with him.


    "Well, put on your helmets. It''s cold outside." Chen Xin took a look at the display screen on the cabin wall and said to the panel of experts who were still sitting in their seats.


    Lucia''s ambient temperature is undoubtedly much lower than that in China, reaching an astonishing 100 degrees below zero. When exposed to this ambient temperature, the moisture in her skin will be frozen instantly, which is the real death temperature.


    Just imagine, your whole body''s skin is frozen in an instant, and the whole person is frozen from a living person to an ice sculpture in a very short time.


    The helicopter frozen in flight in "the day after tomorrow" and the last time Han Zi''ang was frozen in "wandering earth" are enough to show how terrible the temperature is when it is low to a certain extent.


    Of course, in the case of good defense measures, human beings can still survive in this temperature, even outdoor activities.


    At least for these people in Yanguo, as long as they wear protective clothing and sealed helmets, there will be no problem. The only thing to pay attention to is the battery power and oxygen storage displayed by the life monitoring device on the protective clothing.


    As long as the battery still has electricity, the protective clothing can provide enough heat to resist the cold, and it doesn''t need to rely on the outside air at all. Instead, it can only rely on the air circulation inside the protective clothing to obtain the oxygen to maintain life.


    But protective clothing can only ensure the survival of the human body, want to take off the helmet to eat and drink, or need a safe, and the temperature is not so low environment.


    On this point, both Xugou and Haizhu are naturally prepared. When the reinforcements came to the ground, they built a temporary camp to allow everyone to enter and get a safer rest place.


    But for the group of medical experts who have just arrived, they don''t have much time to eat and rest.


    At the first time of landing, with the help of the reinforcements who arrived before and the staff sent by Xugou and Haizhu, they quickly unloaded the materials carried by the aircraft, and then directly put into the intense work.


    "Contact Lucia and ask them to provide the latest virus samples. If you can''t provide them, Xiao Wang will take someone to collect them in person!" The team leader of the expert group is distributing the work. He doesn''t want to waste any time: "if Lucia says that she wants us to help treat the infected people, she says that we have just arrived. At present, she doesn''t have the ability to treat the patients on a large scale. Let them send one or two zombies. Let''s do the analysis first!"Although this shows some callousness and inhumanity, the main purpose of the expert group is to study the virus itself, formulate a treatment plan and develop a vaccine. For the treatment of patients, it is not the work of the expert group, and it will also affect the real work of the expert group.


    "I know! I''ll go right away! " The person called Xiao Wang by the leader answered, turned around and left to find someone to contact Lucia.


    "The rest of the people first set up the camp, and first came to the rescue team comrades to understand the situation, they should also have virus samples, ask how their research progress, first familiar with the situation." The team leader continued to assign tasks, but also looked at Chen Xin who participated in the meeting and said to him, "academician Chen, when will the laboratory on the plane be available? If you can, I need you to debug it as soon as possible, so that we can work


    "No problem, it''s all small things." Chen Xin nodded and agreed without saying anything: "the laboratory has carried out some debugging before coming, which can be used in theory, but I''m not a professional in this field. You have to come by yourself for some detailed parameters."


    At this point, Chen Xin thought for a moment and said to the team leader, "otherwise, you can send someone who knows how to debug this aspect to me and let him cooperate with me to adjust the parameters. It should be available today."


    "OK, I''ll let Xiao Li cooperate with you. He used to be in charge of this work in the laboratory." The leader nodded and sent a man to Chen Xin.


    Chen Xin looked at the person assigned to him by the team leader and gave him a polite smile.

 Chapter 520

    With the efforts of all the experts, the panel soon started its own work.


    Several medical tents have been set up to serve as temporary laboratories and wards for patients.


    Although there is a simple laboratory on the aircraft, which can study and analyze the virus, for the sake of insurance and safety, the team leader asked people to arrange the equipment they brought.


    After all, the laboratory on the aircraft can only carry out virus analysis, clinical treatment research, or need another site.


    After all this was arranged, Lucia''s first infected person was sent to the camp.


    Looking at the infected person, the expert team and the rescue team who went down to the ground again isolated and disinfected the patient for the first time, and then sent it to the negative pressure ward in the medical tent.


    "How is the patient?" Outside the negative pressure ward, the leader in protective clothing inquires the doctor who is checking the patient''s condition in the negative pressure ward through the phone.


    "The patient''s body temperature is very high, and it is difficult to breathe. However, after getting on the ventilator support, his breathing has been normal, and his blood oxygen content has also remained at the normal value. However, his body temperature still can''t fall down, and he may need physical cooling." In the negative pressure ward, after checking the physical condition of the infected person, the doctor reported the situation to the team leader.


    In fact, the early infection of this virus is not very different from the common virus infection. They are all fever and shortness of breath. These are also some common characteristics after the virus invades the human body, mainly the natural response of the human immune system.


    Fever is a kind of beneficial protective mechanism for human body to resist the infection and invasion of pathogenic microorganisms. When the body temperature rises, the activity and reproduction of some pathogenic microorganisms will become less active.


    However, the immune system response of human body is significantly enhanced, including the increase of white blood cell count and the bactericidal activity of phagocytes and neutrophils.


    This is the natural response of the human immune system against the virus and the first line of defense of the human body.


    But there are limits and reaction time in the human immune system. If the virus propagates too fast and exceeds the limit that the human immune system can cope with, all kinds of new diseases will appear in the human body.


    Obviously, the infected person has not been infected for a long time, and the body is still in the stage of the immune system fighting against the virus invasion. At this time, as long as enough medical support is provided, it can help the human immune system overcome the virus invasion.


    In fact, it is also one of the main treatments for most viral infections. By providing help for the human immune system, the immune system can defeat the virus.


    After all, the vitality of the virus is often stronger than that of normal cells. If we kill the virus directly, it will cause greater damage to normal cells to a great extent. If it is not necessary, ordinary doctors will not use the treatment that will cause great harm to the human body.


    In fact, even the medical cabin developed by Chen Xin can quickly cure human injury, but it is based on stimulating cell division and rapid regeneration.


    Limited by the fact that there is an upper limit on the number of cell divisions in the human body, it doesn''t matter if this treatment is used for life-saving or emergency. If it is used frequently, it will shorten the life span if it can''t prolong the number of cell divisions in the human body.


    Moreover, at present, there is no good treatment for the epidemic infection caused by this virus in both Yanguo and Lucia, and there is no specific drug for it. Therefore, this kind of external support to help the human immune system fight against the virus is a more feasible treatment at present.


    Although such a treatment scheme needs more time and medical resources, and the patient''s body may not be able to bear the cost because of poor physical quality, it is the most likely scheme to cure at present.


    And the task of the expert group is to explore the effective treatment scheme for patients. Therefore, in addition to the external supportive treatment, they will also take some experimental treatment schemes for patients.


    However, at present, without knowing the specific situation, the expert panel will not take any radical treatment for the patients, and it is still conservative and prudent.


    "It seems that if it is a mild infection, through supportive therapy, the patient should be able to recover." Chen Xin stood aside, although he couldn''t give any advice on the specific treatment plan, but through the communication with the team leader, he also had an understanding of the harm of this virus: "but if the infection is moderate or severe, I''m afraid it can''t be cured by external support, especially the zombies. I suggest that these infected people try the medical cabin."


    "Academician Chen, what''s the effect of your medical cabin?" The team leader has already communicated with Chen Xin about the medical cabin on the way here. After weighing it, he decided to have a try."There is no actual clinical trial, and I can''t guarantee the specific effect, but it should be better than the effect of the prosthetic instrument I gave to the rescue team." Chen Xin said, looking to the side of a rescue team doctor: "they used the body repair instrument, the principle of the two is the same, but the effect of the medical cabin is better."


    Hearing Chen Xin say so, the team leader also looked at the doctors of the rescue team.


    The doctor quickly said: "the effect of the human body repair instrument is really good, but when we use it to treat the infected people, the effect is not very good. This is mainly because when the infected people were infected by the virus before, there was no damage to their bodies, and the damage of the virus to the human body was not strong.


    In addition, we can''t kill the virus. If we only rely on repairing human body damage, it''s not much different from supportive therapy. Moreover, the repair instrument needs to be used continuously to play a supporting role, so it doesn''t have a good effect on the treatment of infected people. "


    "This has been mentioned in the information they gave me before, so I designed the medical cabin and improved the treatment effect." For the rescue team doctors, Chen Xin did not refute, because it is true.


    After all, the repair instrument is only a temporary repair, which has little effect on the treatment of infected people.


    But the medical cabin is not the same, Chen Xin specially enhanced its therapeutic effect, and increased the function for the virus, which can play a very good role in the treatment of infected people.


    The team leader had already known about these situations in the previous communication, so he thought about it after listening to the doctor of the rescue team and said, "if you have mild infection, try conventional treatment first. Ask Lucia if you have severe infection and" zombies ". Let''s try the medical cabin for treatment."

 Chapter 521

    With the cooperation of Lucia officials and the "revolutionary army", several seriously infected people and a living "zombie" were sent to the temporary camp of Yanguo.


    Needless to say, after the admission procedure, the patients with severe infection were sent to the negative pressure ward for routine treatment and stable condition before they were sent to the medical cabin for treatment.


    As for "zombies", both the expert group and Chen Xin are quite interested.


    "It looks quite aggressive!" The leader looked at the "zombie" who was still ferocious and full of aggressive desire to bite, and sighed.


    Although I have seen countless infected people in my life, and there are many kinds of infectious diseases, some of them are so heavy that people can''t eat for three days, but this kind of "zombie" infected people is really the first time for the team leader to see.


    This made him very surprised, but also a little surprised, because the virus can naturally mutate to such a degree that he could not help worrying about whether the horrible biochemical virus in the movie might also appear in the real world.


    After all, the virus infected by the "zombie" in front of us, after some artificial transformation, is infinitely close to the biochemical virus in the movie.


    The gap between the two is just a reality and a movie, which breaks the constraint of energy conservation.


    If it is based on the reality and the virus infected by the "zombie", it is possible to develop a virus that can spread widely and turn people into "zombies".


    Thinking of this, the leader''s heart suddenly tightens. Although this is a violation of the International Convention and the bottom line of human morality, even before the disaster, all countries in the world have studied biological and chemical weapons in private. Who can guarantee that no one will study this seemingly "invincible" biological and chemical weapons in this situation?


    This terrible possibility made the leader''s heart firm in his determination to develop a vaccine as soon as possible.


    Even if we can not eliminate the possibility of the emergence of biological and chemical weapons, at least to ensure that the virus can be prevented and controlled.


    Chen Xin didn''t know that the team leader had so many psychological activities in the short time when he saw the "zombie". He just looked at the "zombie" in front of him and asked Lucia who sent the "zombie" to him: "are there many" zombie "infected people like this


    "According to the revolutionary army, they appeared in the isolation zone. At that time, dozens of people became such monsters. Some of them were killed on the spot. Only a few dozen of them were alive. Some of them were sent to our medical and scientific research institutions, and the rest were switched off. This is specially for you." The person in charge of Lucia explained to Chen Xin and asked with concern: "can they really be cured?"


    "Theoretically, it''s OK, but we need to do some checks." Chen Xin nodded and looked at the leader: "let''s try the effect of medical cabin with him."


    "Well, academician Chen, you can arrange it." The team leader gave the task to Chen Xin. After all, the medical cabin is his research achievement.


    Chen Xin nodded and said to the people beside him, "after cleaning and disinfecting the people, send them to the aircraft, and I''ll start the machine."


    Then he went out.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    On the aircraft, the medical cabin has been launched, and Chen Xin is checking it.


    The medical cabin was erected close to the bulkhead of the aircraft before. Because of the need to save space, the medical cabin will be erected next to the bulkhead in a folded state when it is not in use.


    However, when it needs to be used, the bracket on the back of the medical cabin will turn the medical cabin over and turn it into a flat state, so that patients can be put into the medical cabin for treatment.


    "Is this the medical cabin? It looks a bit like a coffin... "Xiao Li, who was sent by the team leader to cooperate with Chen Xin''s work, looked at the medical cabin in front of him and couldn''t help saying something. Although he soon stopped talking, Chen Xin still heard what he wanted to say.


    Glancing at Xiao Li, Chen Xin didn''t say anything to him. He just felt that this man couldn''t speak.


    After thinking about it, Chen Xin said to him, "Xiao Li, go to see if the patient has sent it. In addition, let them fasten the restraint belt to prevent the patient from struggling."


    "I see. I''ll go now." Xiao Li, who knew that he had said something wrong, was pardoned and agreed to leave quickly.


    Looking at Xiao Li leaving, Chen Xin shakes his head helplessly, feeling that this person is very unstable.


    However, Chen Xin doesn''t care about it either. Anyway, as long as someone delivers it, the medical cabin can be cured. Other details are not very important.


    Also did not let Chen Xinjiu and so on, very soon, washed peels cleanly, changed a body surgery clothing "zombie" to be sent over."Is this sedative?" Looking at the "zombie" who was much quieter than the active appearance just now, Chen Xin asked the doctor.


    The doctor nodded his head and answered in a positive way: "it was too aggressive before. We couldn''t even clean and disinfect her, so we took an injection to calm her down. It won''t have any effect on the treatment, will it?"


    "It''s OK. It''s more convenient. I don''t design restraint belts in the medical cabin. If I''m too active, I''m afraid I''ll damage the machine." Chen Xin gave a smile and motioned to them to carry people into the medical cabin.


    Looking at the "zombie" carried into the medical cabin, Chen Xin couldn''t help picking her eyebrows. After calming down and washing away the blood stains and filth, the "zombie" is still very beautiful. It''s a young woman with typical Lucian appearance, but the corners of her mouth are torn, which seems to affect her appearance.


    Moreover, the "zombie" looks thin and thin. It should be that he hasn''t had a good meal for a long time. He looks malnourished.


    This made Chen Xin frown and think about it. He said to the doctor: "she may be very weak. After treatment, she will consume a lot of energy. First, give her some nutrition and water to avoid problems later."


    "Well, I''ll arrange for her to be hanged right away." When the doctor heard Chen Xin say so, he quickly asked people to take the infusion set and glucose.


    It is the fastest way to supplement nutrition through infusion. For people who lack nutrition for a long time like this "zombie", the effect is very slow if they rely on food.


    Soon, the glucose and infusion set were brought over, and began to infuse the "zombie".


    After a bag of glucose had been injected into the body of the "zombie", Chen Xin had her carried into the medical cabin, closed the hatch and started the treatment procedure.

 Chapter 522

    Donia felt like she had a long dream. In the dream, she seemed to have a serious illness, and she became a fierce beast. She felt hungry and wanted to bite something.


    Originally, dongnia felt that she couldn''t wake up, but after a warm feeling like soaking in a hot spring, dongnia felt that she was gradually waking up again.


    Hot spring, which has been a very long term for Donia, only when she was very young, her parents took her to visit Lucia''s famous resort once.


    After that, Lucia''s economy became more and more depressed, so that her parents gradually lost their jobs, which made their family''s situation worse and worse. They could not even maintain their whole life, not to mention the luxury of hot springs.


    But Tonya still remembers the warm feeling, just like she is now, wrapped in the warm feeling.


    Are you in a hot spring? Or is she going to be "purified" as an infected person? If the feeling of being "purified" is like this, it''s not bad for Dounia, who has given up her hope of life after the infection.


    "The patient''s temperature is normal, and the blood oxygen content is within the normal range, so the oxygen supply can be stopped." However, a voice rang out in Donia''s ear, saying that she didn''t quite understand Chinese.


    patient? Are you talking about yourself? It''s the doctor talking? How can it be Chinese?


    Because she wanted to live in the country of Yan before, dongnia had taught herself Chinese for a period of time, and even thought about going to a training class. After all, learning Chinese and going to live in the country of Yan are things that some young people in Lucia yearn for after the country of Yan has gradually developed in recent years.


    So you''re not dead? The thought came to Dounia''s mind.


    This idea made her have a little desire to survive.


    Is he saved by Yan people? This thought flashed through donya''s mind. She wanted to open her eyes and at least have a look at what was going on.


    "Academician Chen, the patient''s eyes are open!" In front of the medical cabin, the doctor who had been watching dongnia saw that the "zombie" who had been treated in the medical cabin had signs of opening his eyes, and quickly reported to Chen Xin.


    Chen Xin heard the doctor''s voice, said to him: "check the patient''s physical condition, see if there are adverse reactions, do what you should do, don''t look at me!"


    Chen Xin said that the doctor was very busy. After checking dongnia''s condition, he looked at dongnia who had opened her eyes and asked in Russian, "are you ok? Do you remember your name? "


    "My... Name is... Donia..." Donia opened her mouth. The corner of her mouth seemed to have some pain, and her throat was very dry. She couldn''t speak, but she still said her name and answered the doctor''s question: "I feel very... Warm, but I can''t move..."


    When the doctor heard Donia''s reply, he felt relieved, At least Chen Xin''s medical cabin will bring people back.


    Moreover, the patient has obviously recovered her senses, and the restraint on her body can also be untied.


    The doctor asked other people nearby to help untie the tie, and said to Donia: "your body is tied. Before you were infected by the virus, you became very aggressive. Now we have cured you. Have a good rest and don''t move."


    "OK, I''ll... Rest." At this time, dongnia''s brain was separated from her previous muddle, and she finally opened her eyes and saw the scene in front of her. So she said in stumbling Chinese: "thank you


    Everyone in front of the medical cabin laughed when they heard the voice, which was so Maowei and out of tune that they could hardly hear the Chinese "thank you".


    "First, send the patient to the intensive care unit to check her physical condition and the virus. Although the medical cabin cured her, she can''t be careless." Chen Xin gave orders to the doctor on one side, then motioned them to carry dongnia on the stretcher and send her away.


    The doctor nodded, and together with the others, he lifted donya out of the medical cabin and launched the aircraft.


    Seeing that dongnia was pushed away, the leader who had been watching the whole process congratulated Chen Xin: "Congratulations, academician Chen! Your medical cabin cured this patient, which proves that this is a great invention! "


    The leader really thinks that the medical cabin is great. After all, he clearly knows how dangerous the virus is, and what kind of disaster it will bring to the world if it becomes a biochemical weapon.


    But now, at least, they have a way to treat the infected people. They are not helpless in the face of viruses or biological and chemical weapons.


    For the leader''s praise, Chen Xin shook his head with a smile: "it''s a good thing to be cured, but there is only one medical cabin! The manufacturing cost of this thing is very high. If there is no second one in a short time and the technology can not be promoted, the importance of this thing is not as high as you think. "It''s not that Chen Xin is unwilling to promote the medical cabin, but the investment needed to make this thing is really high. Even if he made this medical cabin himself, he spent 5-digit survival to upgrade it to the current level, which can be used to cure the "zombies" infected by the virus.


    "You can''t say that! First of all, we need to solve the problem of whether or not we have it. We need to consider mass production, scientific research and innovation. Ideas and innovation are the most important. Only when we have new technologies can we consider promoting them! " The leader complimented Chen Xin, but he didn''t say much.


    After all, he was not a person who liked to compliment others. After a few words, he turned the topic back to the epidemic.


    "Academician Chen, your medical cabin here can cure the zombie infection. Now the most frightening crisis has been solved." The team leader also knows how powerful the "zombie" is. Now that he has a solution, he can naturally focus more on the treatment of ordinary patients: "I don''t know if the medical cabin for ordinary infected patients can provide treatment?"


    As for this question, Chen Xin thought about it for a while before answering: "at present, it is possible to treat it, but I still don''t recommend that ordinary mild patients should use the medical cabin. If severe patients can''t use the ordinary therapy, they can use the medical cabin for treatment, but it also needs to consider the physical condition of the patients, Just now, the patient was obviously too weak. Some of them could not bear the body consumption caused by medical cabin treatment. "


    "This is really a problem. It seems that if we want to use the medical cabin for treatment, we still need to supplement the patient''s body first." The leader nodded, thinking seriously about how to solve this problem.

 Chapter 523

    In the area under the control of the "revolutionary army", because the Revolutionary Committee has started negotiations with the officials, the atmosphere here has changed slightly.


    Most of the members of the "revolutionary army" were rioters at the beginning. They resisted the government because they felt that they could not survive. They and the government were hostile. But now the Revolutionary Committee has begun to negotiate with the government, which undoubtedly shakes many people''s trust in the Revolutionary Committee.


    After all, the so-called revolutionary committee did not have a mass base. At the beginning, the rioters just needed a leader, and the so-called revolutionary committee rose with the tide.


    If the Revolutionary Committee can deal with the problem well and convince all people, then their ruling foundation can be gradually established.


    However, within a month after the founding of the whole "revolutionary army", there were negotiations with the biggest enemy and the target to be overthrown, and it was inevitable that there would be vacillation.


    It''s easy to say if only the trust in the Revolutionary Committee has been shaken, but obviously a small group of people do not just distrust the Revolutionary Committee, but want to replace it.


    In one of the refuges held by the "revolutionary army", a few people with ulterior motives have gathered together.


    "I went to ask, the Committee sent a zombie to the official side, they cured the zombie through the Yan people." One of the masked men revealed to the others what he had heard.


    The news obviously surprised others. After a whisper, someone asked, "are you sure?"


    "Sure, the source is from the Committee." The masked man did not say from whom the news came, but he certainly convinced others.


    Or, for others, whether they are convinced or not depends on what they want to believe.


    "Since Yanguo people can treat infection, why does the committee not negotiate with them, but have to go through official consultation?" Questions have been raised.


    "Because Yan people and the government are in a group! They''re all in one group! " One of them said excitedly, and the excitement on his face couldn''t even be covered with a mask: "do you really think they are here to treat the sick and save the people? no I''m telling you, they''re here to do human experiments with us!


    These viruses! Do you know? These viruses can be used as weapons! This is a biological weapon! They are not the ancient virus released by the thawing frozen soil in Siberia, which is officially developed biological and chemical weapons!


    Are Yanguo people saving people? no They''re experimenting with infected people! Don''t think that they are saving people with good intentions. They are making biochemical weapons with our people! "


    "Shut up! You''re too loud! Are you trying to bring in the committee? " Seeing that the more he said, the more excited he was, someone suddenly yelled at him and stopped him from going on.


    The masked man who began to speak saw that everyone was quiet again, and then he continued: "although the committee is negotiating with the officials, it is obvious that they have no way to contact the Yanguo people, and as just said, the Yanguo people may not have the idea of saving people, otherwise they have the means of healing. Why don''t they help us?


    So far, there has been no news of sending infected people to the Committee for treatment. They said that they had negotiated with the official. Only a few core members of the Committee knew what they had talked about. Even many people inside the committee did not know what the official and them had achieved. "


    "Isn''t that to say that the revolutionary army was sold because of the agreement reached between the Committee and the government in private?" Some people think it''s unbelievable. Although they don''t trust the Revolutionary Committee very much, there are still some people who have some good feelings and expectations for it.


    However, if some people have a good opinion of the Revolutionary Committee, naturally some people have a bad opinion. Soon some people chimed in and said, "who knows who the Revolutionary Committee is? They just stood up and organized during the riot. Most of them were just children! Whether they are reliable or not, who can guarantee that they are not in collusion with the authorities? "


    "It''s reasonable. I think the purpose of the negotiation between the Committee and the officials is to betray us so that they can get more benefits!" A guy who looks big and heavy said, although also covered his head, but he didn''t look as yellow and thin as others.


    "What should we do now? What should we do if the Committee sells us and sends us to the government and Yan people for biochemical experiments? " Some people have asked about other people''s concerns, although this is nonsense.


    "Then we will overthrow the rule of the committee just like we did before overthrowing the official rule!" Some people are very radical.


    "No, the biggest problem now is that the infected people can''t get treatment. No matter what the committee is doing, at least the stable order now can allow more people to get treatment." Some people prefer a more secure solution.It''s just that neither of them is obviously supported by the majority, and more people seem to be inclined to survive and get treatment than radical programs.


    This is of course the most appropriate way for ordinary people, but it is obviously not in their interests for those who want to.


    "Since Yanguo people have the technology to treat zombies, they must be able to treat infected people. Why don''t we arrest Yanguo people and force them to hand over the treatment methods to treat more people?" Some people seem to have put forward a more feasible option for everyone.


    Hearing someone put forward this plan, the prepared insiders also cooperated and said: "that''s right! The government and the Committee don''t care whether we live or die, so we can make a living by ourselves! Arrest the people of Yan country and force them to hand over the method of treating epidemic disease! "


    "Yes, we have to actively help ourselves! Since Yan people have a treatment, we''ll grab it! " Another insider also loudly echoed, and raised his hands to propose: "since the Yan people can come to Lucia, it proves that they have a plane! We can grab the plane and drive it out of this damn place! "


    "Leave Lucia? But where can we go without Lucia? " Leaving Lucia is really something many people want to do, whether before or after a disaster.


    "Equator! We''re flying to the equator! No matter how cold the weather is, the equatorial region will be warm! " So cried the premeditated, inciting others.

 Chapter 524

    Lucia is a magical land. It produces many things, including talented musicians like Tchaikovsky, literary giants like Tolstoy, Gorky and Pushkin, and famous painters like Lebin.


    Not to mention the birth of the famous ballet genre, Lucia ballet, in this country and race, which is playfully known as the fighting nation.


    People have to marvel at how such a rough looking, even somewhat barbaric country has bred such a splendid culture.


    It''s just that Lucia produces an amazing culture, as well as something that goes well with the fighting people: the lucians, who are always called maozi.


    At first, the word "maozi" was a derogatory term.


    However, with the development of the times, the derogatory meaning of the word seems to fade away gradually, with a unique descriptive flavor.


    Mao style equipment, Mao style maintenance, Mao style rescue... And so on, it seems that this has become the exclusive description of lucians. As long as you mention Mao Zi, you can understand what you want to say.


    Although there is a suspicion of stereotype, we have to say that the way of thinking of lucians is quite different from that of people from other countries and nationalities in some aspects. They always like to choose a simple and direct method, even if it costs more.


    This was true in the old days of suvia, and it is also true in Lucia today.


    Outside the temporary camp of the state of Yan, a group of lucians, who wrapped themselves up like rice dumplings with all kinds of things they could find, were negotiating with the soldiers on guard.


    "Hello comrade, we are members of the revolutionary army. We are transporting infected people for treatment. Can we go in?" A burly man was negotiating with the Yanguo soldier in power armor, who was much thinner in front of him, and tried to take something out of his pocket to bribe him.


    But the soldiers of Yan country are obviously different from the police of Lucia. They can''t be bought by bribery.


    "Sorry, I can''t take your things, and I haven''t been informed that I can let you in, so I can''t let you in." The thin soldier sidled over the things handed over from the opposite side, and at the same time, he seriously and resolutely refused the other side''s request.


    This seems to make the burly Lucia man feel very embarrassed. A big man, who is very humble in front of the soldiers, earnestly begged the other side: "comrade, these are all innocent infected people. They can''t be saved if they can''t get treatment. Do you think you can accommodate them? Let''s go in for a moment. "


    However, the soldiers of Yan country just shook their heads and didn''t have the idea of accommodation at all.


    "I have no authority to let you in, and I have not been informed that I can let you in. If you want to go in, please negotiate through formal channels." Yan soldiers did not put forward a cold face, or pointed out a feasible plan for the other side.


    If the strong man of Lucia is really just sending infected people for treatment, the advice given by the soldiers of the state of Yan is more practical and feasible. As long as he responds to the Revolutionary Committee and contacts the state of Yan through the official channels of the Revolutionary Committee, naturally someone will arrange the treatment of these infected people.


    But it is obvious that this strong man of Lucia, the people who came with him, and even the so-called "infected people" who were carried on the stretcher, are just a group of guys with ulterior motives.


    Under the promotion of some people behind the scenes, they plan to infiltrate into the camp of Yanguo people in this way, and then create chaos from inside the camp, so that Yanguo people can''t afford to fall into chaos, so they take the opportunity to kidnap the doctors who treat the infected people and snatch the treatment methods.


    A small number of core elements among them even have a further plan, that is, to seize the plane of Yanguo people, so that the people behind the scenes can fly to the equatorial region with better living conditions.


    From Lucian''s point of view, it''s good to come up with such a plan, at least it''s a very feasible plan.


    If Lucia''s own army is stationed here, this plan is likely to succeed. Even if it is replaced by the Yan army before the change, this plan is not without feasibility.


    After all, they also have weapons hidden under the stretcher. If they can''t mix in, a strong attack is also an alternative.


    But what they are facing now is not the Lucian army with the same firepower level or the Yanguo army without changing clothes, but the elite Yanguo special forces equipped with military exoskeletons and electromagnetic rifles.


    In such a situation, a strong attack can only be a head drop.


    However, maozi is maozi. Even if someone made a plan for them behind their back, after several unsuccessful attempts to persuade the soldiers on guard, several rioters who could not stand the cold still pulled out their ancestral AK directly from the stretcher and launched an attack on the soldiers on guard."Ding Ding Ding!"


    The bullet made a string of sparks on the military exoskeleton of the soldier. Although it did not break through the bulletproof guard plate on the exoskeleton, the soldier who was caught off guard was repelled by two steps.


    With the help of exoskeleton, the soldier quickly set up an electromagnetic rifle and began to counterattack. With several precise shots, he knocked down several rioters at the head. At the same time, the soldier also quickly called for help through communication equipment.


    "Emergency! Lucians are shooting at me at the door. Ask for help Although the soldier was asking for help, he didn''t show any nervous or flustered mood. He just used the surrounding bunkers to call the names of those Lucian rioters with their ancestral AK in their hands.


    Although AK''s bullet is still very lethal, but for this soldier, it was just caught off guard at the beginning, and he was bitten by a bullet on his arm, which did not cause any harm to him.


    Even if the arm can''t be used for a while, with the help of exoskeleton, the soldier can hold the electromagnetic rifle in his hand with his arm and shoot steadily without any effort.


    Although they didn''t deliberately shoot at the lethal parts, when reinforcements arrived and ended the attack that didn''t bring much trouble, most of the Lucian rioters were killed, and only a small number chose to surrender and survived.


    After a simple treatment of the prisoners'' injuries, they were pointed at with guns and began to clean up the bodies on the ground. They planned to join the prisoners and hand them over to Lucia''s authorities for treatment. The wounded soldiers also received good treatment.


    Just at this time, a rocket was suddenly fired from outside the camp, hitting the prisoners who were carrying corpses at the gate of the camp, causing a violent explosion.

 Chapter 525

    "Come on! This way An officer is directing his soldiers to pass quickly at an intersection under the capital of Lucia.


    Looking at the armed troops who were rushing into the passage on the other side of the road, the officer emphasized loudly: "all the suspects should be arrested! Kill all the rebels! Don''t let go of anyone who is suspected! "


    Although he was only an elite special force subordinate to the intelligence department, this officer had the demeanor of the anti insurgency workers in the Soviet era.


    However, after the attack on the camp, the atmosphere in Lucia''s capital at this time will not be much worse than that at the peak of the Anti Japanese war.


    Even if the last rocket was included in the attack, the casualties were mainly concentrated on the attackers. Almost all the rioters died. Except for those who were killed at the beginning, only two of the prisoners who had surrendered survived and were injured.


    As for Yanguo, there was not much loss. Four people were slightly injured and one was seriously injured. After being carried to the medical cabin, the seriously injured were soon cured.


    However, the nature of this incident is extremely bad, and the impact is also extremely serious.


    The people of Yan state withdrew all the people on the ground at the first time. After the two ark evacuated all the people and materials, they quickly rose to an altitude of one kilometer and made solemn representations to Lucia.


    If Yan people didn''t respect Lucia''s sovereignty, it would be time for Titan to call Lucia''s leader''s office.


    In the face of the questions from the Yanguo people, Lucia''s leader wanted to lift the table at this time.


    Originally, Yanguo agreed to the aid that had been discussed before, and sent medical experts to help research and crack the virus and solve the epidemic problem. Everything has been developing in a good way, and Lucia has gradually had the hope to tide over the crisis.


    But it was all ruined by the attack.


    Lucia''s leaders dare not think about what the country would look like if the Yanguo people left the rescue team now, under the double attack of epidemic and cold.


    Although suvia was a giant oppressed by the whole world at that time, now Lucia is just a remnant of the body of this giant. With the gradual depletion of nutrients in the body over the past few decades, Lucia is just barely maintaining the appearance of a big country.


    And this disaster drained Lucia''s last strength. She was unable to cope with an epidemic, which led to riots in the capital. Now this is even more so.


    In the face of such a crisis, Lucia''s leaders no longer want to think about any proper solutions. As he once said, there is only one attitude towards these behind the scenes troublemakers. No matter where they hide, they should take them out! Grab him in the toilet and drown him in the toilet!


    The army, which had been mobilized to suppress the riots, had not moved for a while because of official negotiations with the revolutionary army, but now all the troops are in action, and they are searching for people related to the backstage in Lucia''s capital.


    In fact, it''s not hard to guess who is behind the scenes, and Lucia''s leader himself knows very well.


    They used to be the people who benefited most from the huge corpse when suvia disintegrated. Most of them once held the economic lifeline of the whole country of Lucia. To some extent, their will at that time was the will of the whole country of Lucia.


    It was after the collapse of suvia that they became the oligarchs in charge of the country.


    Although the seven oligarchs who once controlled the country were defeated after the current leader of Lucia came to power, they still exist in the country.


    After all, the old oligarchs fall down and the new oligarchs stand up. As a world-class power, Lucia has never been short of rich people despite her poor economic situation.


    But when the disaster came, these rich people, old and new oligarchs, especially the oligarchs and rich people involved in the financial industry, suffered heavy losses. With the complete cessation of financial activities, their huge wealth evaporated overnight.


    Although most of them have prepared solid and reliable private shelters for themselves before the disaster, it can only keep them alive.


    Maybe they live a lot better than ordinary people, and even some people listen to them. But compared with the power and wealth they once had, they are not worth mentioning at all.


    Some rich people may think it''s good to live, but some people are not willing to lose their rights and status.


    In fact, Lucia''s intelligence department had caught their shadow in the previous riots, but the impact of the riots on the capital was too big, and the impact of the epidemic made the situation out of control. These people took the opportunity to hide, and even gave birth to the revolutionary army, a more thoughtful organization, which made Lucia''s official ignore these people temporarily.But when they jumped out to make trouble, especially after such a big mess, as Lucia''s leader who used to be in the intelligence department, they directly decided to solve the problem with Mao''s method.


    Catch all of them, and then kill all of them.


    Just as Comrade iron and steel did in those years, although it was overdone, we have to say that from some angles, the effect was excellent.


    This gave the order that all the troops that had been used to suppress the uprising should go out to arrest all the suspects and kill all the rebels.


    In the face of the large-scale official action, the revolutionary army was of course very nervous, but the Revolutionary Committee acquiesced in the official action and even provided cooperation after asking the official what happened.


    This naturally makes the official action more smooth, but it also makes the behind the scenes more panic, so that they jump out of the wall.


    The gunfire once again rang out in Lucia''s capital, but compared with the last riot, the fighting this time was undoubtedly much more fierce.


    Behind the scenes are the once rich and oligarchs. Although most of their wealth and power are gone, they can still use a lot of power.


    It may not be able to resist the official crackdown, but it is not a problem to bring chaos back to bear.


    So for a moment, the whole underground of Lucia''s capital became a battlefield.


    Innocent people hid in their hiding places, covered their ears, wrapped up all the covers they could find, trembling endlessly, looking forward to the end of this turmoil earlier, or they could die faster and get out of this cold human hell earlier.

 Chapter 526

    On the ark, Chen Xin sat in his room reading books.


    Yanguo''s original rescue operations and Research on the virus and vaccine have been suspended.


    Because of the attack, the temporary camp on the ground was demolished for the sake of safety, all materials and equipment were transferred to the two ark, and the aircraft also returned to Yanguo after emergency takeoff.


    The demolition of the temporary camp also means that the treatment of infected people in Lucia and the research on the virus cannot continue.


    Although it is said that we can rearrange the equipment on the ark and continue the research on virus and vaccine, we can give up the research on the ground at any time. Once there is an accident such as virus leakage on the ark, the impact will be out of control.


    However, the virus samples have been properly preserved, even if they return to the country of inflammation can continue to study.


    Although the research work on the virus can no longer continue, the previous patients with Lucia infection have recovered after treatment.


    After a period of observation, they will be sent to the ground by airship and handed over to Lucia for official treatment.


    As for the crew members who were infected with the disease before, they also received proper treatment during this period, and now most of them have recovered.


    In fact, under the current situation, the two ark ships can return home, and there is no need to take care of Lucia''s affairs.


    It''s just that they can''t just walk away until they''re officially ordered to leave.


    So now the two ark hovered at an altitude of one kilometer above the capital of Lucia, waiting for the final domestic opinion on this matter.


    As for how to deal with this issue in China, most people still hope to continue to complete the work at hand, although some people feel that even if they go back to be criticized, they should give priority to ensuring their own safety.


    If you can''t guarantee your own safety, don''t talk about helping others.


    The two views have their own reasons, and many people support them. However, after discussing with Chen Xin and the leader of the expert group, the captains of the two ark decided that even if they wanted to leave, they would have to wait until the official order from China.


    Originally, after the attack, the captains of the two ark wanted the expert group and Chen Xin to go back by aircraft first, and the reinforcements to go back by the transport helicopter when they came.


    After all, relatively speaking, both the expert group and Chen Xin are of great value to the country, and all kinds of new weapons on the side of the reinforcements are also important materials, which should not fall into the hands of those with ulterior motives.


    However, after discussing with the leader of the expert group, Chen Xin just asked the transport helicopter to transport the Titan back, while the aircraft took a virus sample with several members of the expert group.


    And they themselves, together with the reinforcements, boarded the ark "Hai Zhu" and planned to wait for the official orders from China together with the two ark.


    The ark itself can accommodate a lot of people. Although there are so many people at once, they can still live. So the captains of the two ark did not object to this decision.


    But it''s hard for Chen Xin.


    The purpose of the expert group and him to stay is to prevent the country from allowing them to continue their mission. Although this possibility is not high, if Lucia officials can successfully suppress the situation and persuade the domestic high-level officials in a short time, it is still possible for the country to agree that they will continue to stay and provide assistance to Lucia.


    Although the possibility is not high, Chen Xin and the team leader of the expert group tend to wait for a while rather than go back and turn around halfway.


    Under such circumstances, the expert group can continue to do their work. After all, there are still a few infected people who have not recovered on board the dog. They can continue to study the treatment plan. Although the research work on the virus has been suspended, they will not have nothing to do.


    But Chen Xin''s side is different. When he came here, he needed him to debug and operate the medical cabin. Now the medical cabin goes back with the aircraft, and he seems to have nothing to do on the ark, so he can only read in the cabin assigned to him.


    Although such a day is not hard, it is hard for Chen xinlai to say that he has nothing to do.


    This is the first time in such a long time that he felt free after the impact of the meteorite.


    He had been busy with all kinds of things before he became an academician. Before he became an academician, he had to be busy for his own survival. After he became an academician, he had to be busy for all kinds of work and things at hand. In fact, he seldom had a real leisure time.


    After all, the pressure of survival and the pressure of work made it difficult for Chen Xin to be idle.However, at the moment, it''s like taking time off in a hurry. Chen xinjiufei feels that he''s at leisure when he can calm down and read books on the ark.


    But this kind of leisure can only be temporary. After all, even if he can take a little vacation, the situation of the whole world is still so bad, and the pressure and threat of survival still exist. Under such circumstances, it is difficult for him to get real leisure.


    Especially now Chen Xin''s identity, even if the environment of Bluestar returns to normal, as an important scientific researcher, he still has a lot of work to do.


    With this in mind, Chen Xin suddenly feels that his original choice of cooperation with the state may be a wrong choice in a sense.


    Chen Xin can''t help but ask himself sometimes, if he didn''t choose the way he is now, but in a more selfish state, he just used the system to make himself better, didn''t consider the survival of large-scale harvest, but only relied on himself to build a refuge to get survival, maybe it should be a completely different situation now?


    In that case, although survival is slow, Chen Xin''s consumption and demand for survival are not so great.


    After all, in that case, he basically only needs to bear his own survival needs, plus his parents, Mo Qingyan and Qin LAN at most.


    Chen Xin simply thought about it for a while, but found that even if he went back to the beginning, he would still choose to cooperate with the country and reap the survival. It would not be much different from now. It was only to cooperate with the country in a way that was not so close to the country.


    In any case, Chen Xin doesn''t feel that he can be the kind of person who can watch others struggle on the line of life and death, but he can lie in a warm and comfortable place to eat and drink, and has no ambition to conquer or dominate others.


    With this time, it''s better to think about how to improve the current blue star environment and find a way to make the sun reappear.

 Chapter 527

    After reading for a while, Chen Xin put down his books and walked to the cockpit of the ark.


    The atmosphere here is much more tense than before. After all, they have been attacked. The two ark are now in a state of war readiness. The light control has even been implemented in the ark, and the cockpit is no exception.


    However, although the lights are controlled, they will not go dark.


    Chen Xin went to the captain of the Haizhu and asked him, "what''s the situation now?"


    "At present, there is no latest instruction in China. We and Xugou are still on standby." Seeing that it was Chen Xin, the captain of the Hai Zhu nodded at him and then explained, "as for Lucia, they have been keeping in touch with us. According to the latest information shared, the war situation in the capital of Lucia is now in a state of anxiety."


    "Anxious? Why do you use this description? " Chen Xin is very curious that the war situation has turned into anxiety. Is Lucia''s official decline to such a point that it is impossible to suppress a group of oligarchs behind the scenes by joining hands with the revolutionary army?


    The captain of Haizhu naturally read out the meaning represented by the expression on Chen Xin''s face, and he was very helpless: "no way, although Lucia''s official troops attacked in the first time with the cooperation of the revolutionary army, those oligarchs'' armed forces were not vegetarian.


    Most of them were mercenaries they had raised in the past, and their combat effectiveness was not bad. Moreover, some of these oligarchs controlled military industrial enterprises, and their weapons and equipment were not inferior to those of the regular army. In the bunker built by those oligarchs, there were even war guns, which caused great trouble to the attack of Lucia''s official forces. "


    Chen Xin can understand the difficulty of the attack when he hears that there are anti Japanese guns.


    Anti tank gun, also known as anti tank gun, is a kind of gun with low trajectory, which is mainly used to damage enemy tanks and other armored targets.


    Generally speaking, it is arranged on the battlefield to resist the attack of armored group, but if such a gun is arranged in a narrow passage, even if Lucia''s official Army can drive the tank in, it is only a live target, and it is still a fixed target.


    It''s like you block the only exit of the ant nest. All ants can only come out from this exit, but you put a spray gun on the place opposite the exit. As long as the number of ants is not enough to block the spray gun, no matter how many ants come out, it''s meaningless.


    Although the artillery is not a spray gun, Lucia''s official troops are not ants. They can''t even compare with the suvian army or the earlier Russian gray cattle.


    So it''s not surprising that the oligarchs have such weapons and equipment, and the war situation becomes anxious.


    This kind of situation changed Yan country to attack, but can rely on the heavy machine armor''s 50 mm short tube recoilless gun to knock down the opposite defensive gun.


    But for Lucia''s official Army, one gun was enough to make them helpless.


    After all, it''s impossible for the other side to use only one artillery to block the passage, match it with two heavy machine guns, sweep the small penetration with machine guns, and fire the large-scale attack. It''s very difficult to break through such a defense line before the ammunition is exhausted.


    As for the heavy firepower such as rockets, Chen Xin believes that Lucia''s official Army must have used it, but since the oligarchs have made defensive artillery, they must be ready for defense.


    It''s much easier to build a strong enough shelter with high-grade reinforced concrete than to get a war cannon underground in the capital of Lucia.


    "What are they going to do now? Is that all? " Chen Xin shakes his head. If so, there is no need for them to stay. If they drag on like this, there will be only one result, that is, Lucia''s capital will not be saved.


    As for Chen Xin''s question, the captain of the Haizhu shook his head and said, "it''s not that. They''re trying to get around that artillery. At least they''re regular troops, one of the five regular armies. They can''t even get one artillery. It just takes time."


    Lucia''s army can solve the problem, which neither the captain of the pig nor Chen Xin doubt.


    However, it is uncertain how long it will take them to solve the problem.


    "Did they ask us for help?" Chen Xin is more concerned about this issue. After all, when the war is going on like this, Lucia''s leaders estimate that their blood pressure is full. It''s not something to consider asking them for help at this time.


    After all, what Yan has in his hands is an easy way to solve the problem.


    "Lucia''s leader personally sent us a message for help, hoping that we could lend the Titan to them to break through the defense lines of the oligarchs'' armed forces. However, considering that we did not receive domestic orders and the possibility that the Titan might be destroyed, I discussed with the captain of the xuygou and did not agree." The captain of the Hai pig did not agree with what he said here. Of course, he did not refuse directly. Instead, he asked Lucia''s leaders to contact China directly.After thinking about it, Chen Xin asked the captain of the Haizhu, "what caliber of artillery are they using?"


    He had to assess the level of force used by the oligarch''s armed forces and calculate the possibility of being destroyed if Titans were used to face the artillery.


    "It''s 75mm caliber, and it''s an old model. Although its power is average on the battlefield, it''s really easy to use in this situation. Moreover, the other side has a lot of shells in reserve, and the lucians really can''t get in for a while." The captain of the Hai Zhu shrugged. As a naval officer, he didn''t think it was a big caliber. The 75mm caliber was only a small caliber toothpick on the World War II naval ships.


    75mm It''s very difficult to penetrate Titan''s defense with caliber artillery, as long as it''s not armor piercing bullets, especially the two titans have shields.


    "Titan can block this caliber." Chen Xinmo rubbed his chin and suddenly thought of something. He asked the captain of the Hai Zhu, "if our soldiers are not equipped with Titan and heavy mecha, how do you take down this anti-aircraft gun?"


    In the face of Chen Xin''s question, the captain of Haizhu gave a serious thought before answering: "I''m the Navy. If this happens, we will call fleet artillery support or air support directly to destroy the target with saturated fire.


    Although this is a common tactic of the federal army, when it comes to such a firepower base that will be difficult to break through for a while and a half, it is the most inadvisable way to take human life to fill in! Of course, if there is no other way, our soldiers will not be afraid of sacrifice. "

 Chapter 528

    Yanguo has new equipment that can be used for breakthrough, and the conventional tactics are not without artillery. Although the lucians have no new equipment, they also have no way in conventional tactics.


    In this case, Yan people may instinctively think about tactics, and make a breakthrough around the enemy''s weak defense. However, Lucian''s tactics are not so flexible. They are more used to hammering walnuts and making a direct breakthrough.


    Of course, no matter how reckless the lucians are, it is not enough to say that the army is facing a direct attack from a defensive gun.


    They are no longer the suvian army that only had spiritual belief as a guide, and there is no blue hat that can take the lead in charge. After losing their belief, although the combat effectiveness of the army will not drop too much, its ability to fight hard battles will drop a lot.


    What''s more, for Lucia''s army, although the current situation is difficult to solve, it is not impossible to say that there is no solution. Even if there is no need to attack, they are not helpless.


    "Did the special ammunition arrive?" The commander of Lucia''s official Army inquired to the combat staff beside him that the so-called special ammunition was the winning weapon to solve the problem of the artillery blocking the whole passage.


    The staff officer nodded and replied in the affirmative, "it just arrived a few minutes ago."


    "Let a combat team carry the special ammunition, find the vent of the enemy''s stronghold, and then drop the special ammunition." The officer gave the operational order with a gnashing of teeth attitude: "at the same time, we use special ammunition in the front of us, and directly hit it through the launcher!"


    "Yes, commander!" The staff officer answered and immediately went to pass the order.


    The so-called special bomb is a kind of special smoke bomb made of nerve gas. After use, it will quickly release a large amount of toxic gas and paralyze the nerves of the inhaler.


    Lucia''s army once used this kind of thing in a hostage rescue operation, and the effect shocked the whole world. Although it caused some unnecessary casualties, this kind of nerve gas is really very useful.


    Under normal circumstances, Lucia''s military will not use this kind of thing, but now, in any case, it is not normal. Naturally, this unconventional means has no restrictions on its use.


    This kind of special ammunition can be pulled open by hand, and then thrown out like a hand grenade by manpower. Of course, it can also be used as a gun grenade and fired out with a rifle.


    Although the range is not too far, it is enough in the current situation. After all, the use of nerve gas is very environmentally friendly. If it is used in an open field, it needs to be hit on the enemy''s position with a mortar or other launcher.


    But in such a closed underground environment, as long as the special ammunition is shot into the tunnel and close enough to the target.


    As expected by the commander, although the armed men tried to disperse the nerve gas in the passage through the air flow after the firing of the anti-aircraft guns after discovering that the official forces of Lucia used special bombs, they had no effect because of the insufficient distance.


    Although these armed men also have gas masks, they put on gas masks for the first time after they found that Lucia''s official Army used nerve gas, but this did not stop Lucia''s official offensive.


    Half an hour later, Lucia''s official Army had entered the previously blocked underground passage very leisurely, and found out the armed elements hiding in the shelter built by the oligarchs one by one, and all those who resisted were killed.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Although the resistance of the oligarchs behind the scenes has been destroyed and all the suspects have been caught, it is far from over for Lucia''s leaders.


    It''s true that the people behind the chaos have been caught, but their influence has also happened and become an established fact.


    Affected by this, the cooperation originally reached between Lucia and Indonesia has been suspended and suspended. It is obvious that a new interest exchange and arduous negotiation are needed to resume.


    But it''s easy to say that Lucia''s diplomats who had nothing to do after the meteorite impact would be happy to do these things.


    However, the issue of Heyan can be solved only by diplomats'' smooth talk and paying for the things that pressed the bottom of the box in the suvian era, while the issue on the other side is not so easy.


    Before these oligarchs who made trouble behind the scenes, they spread a lot of anti official remarks in the "revolutionary army" camp, and controlled some forces within the "revolutionary army". Before that, they made good use of these people, incited their hostility, and used them to resist the suppression of the official Army.


    Although these people, together with the oligarchs and the armed forces they controlled, were suppressed in the subsequent battles, they were all part of the "revolutionary army" in any case.In addition, the government and the "revolutionary army" simply reached a cease-fire agreement, so after these people were suppressed, the relationship between the "revolutionary army" and the government has reached a very dangerous level.


    Although it didn''t turn over at once, it was almost a draw of swords. It was just a matter of firing.


    Although the suppression of the "revolutionary army" was a planned and easy task for Lucia officials, Lucia''s leaders did not want to do so.


    Because the capital of Lucia is in a mess now. If order and production cannot be restored as soon as possible, the whole capital will collapse in a week.


    Moreover, not only that, the war''s damage to the city is amazing. Although the overall underground structure of the capital has not been damaged, many places have been beaten to pieces in the previous conflicts.


    If there is another big conflict or even war, Lucia''s leaders can directly announce the move of the capital.


    Although at the beginning, the leaders of Lucia had made up their mind to suppress the riot even if the whole capital was smashed, but the problem had not been completely solved even if the capital was smashed, Lucia''s leaders had lost their determination to burn their boats.


    After all, Lucia is not such a populous country as Yanguo. There are only a few big cities in China, and only a few of them have underground refuge facilities that can accommodate a large number of people. Most of them were built in the Soviet era, and the capital is the one with the most perfect facilities.


    After abandoning the capital, there is only one other city in Lucia that used to be the capital, but because it is a harbor city, it has been engulfed by the rising coastline and frozen under the ice.


    For Lucia, they couldn''t afford to lose the capital.

    Lucia wants to keep her capital. It''s impossible for her to do so on her own.


    No matter the riots caused by the "revolutionary army" or the war brought by the oligarchy, they all caused irreversible damage to the order of Lucia''s capital and made the official rule of Lucia crumble.


    Although the army and country are still in the hands of Lucia officials, they have not many cards to play at this time, and there is no good way to change the current terrible situation.


    In addition to ask for the last help from Yanguo.


    Although in the past to ask for help, Lucia has taken out a lot of pressure box bottom of the family, this can move the country, in this kind of countries are now too busy to draw out valuable strength to help Lucia.


    But it has to be said that as a superpower that once oppressed the whole world for half a century, even if it died, after 30 years of consumption, the legacy it left behind is still amazing.


    Lucia''s official has come up with a new chip, so that the high-level of Yanguo has to reconsider whether to help Lucia tide over the difficulties.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "What on earth did Lucia take out to make the senior management agree that we should stay and continue to help lucians?" On the ark, the commander of the former reinforcements was listening to Chen Xinda.


    After suppressing the turmoil caused by the oligarchs, lucians reached a new agreement with the high-level officials of Yan state again, and paid the price in exchange for the continued assistance of Yan state to Lucia.


    As for what kind of chips did Lucia take out to get the approval of the senior management of Yan state, it naturally became a very curious question for everyone.


    However, it is obvious that the top management will not let the bottom people know about this kind of thing. Therefore, among all the people in Lucia, only Chen Xin knows the specific situation.


    Now, accompanied by the officials sent by Lucia, he is going to check the things brought out by the lucians, and the former reinforcements have now become his bodyguard, responsible for providing him with personal protection.


    As the commander of the reinforcement force, he can still know some information, which naturally makes him curious about what lucians have come up with to persuade the top.


    Although as a soldier, he clearly knows that there are confidentiality regulations and he can''t inquire about things that shouldn''t be inquired about, as Chen Xin''s bodyguard, they are going to check and accept the thing with Chen Xin next. At that time, they will naturally be able to see what it is. Now they just want to know in advance and satisfy their curiosity.


    Chen Xin can certainly understand the curiosity of the commander of the reinforcement force who wants to know what that thing is, but he just sold it at this time and said with a smile, "you will know in a moment. In a word, it will surprise you."


    Chen Xin naturally already knew what the lucians had brought out. To be honest, he was also very surprised that the suvians actually made that kind of thing.


    When he saw the land cruiser sealed up by the suvians before, Chen Xin was already amazed by the technology of the Cold War era when the two poles were competing for hegemony, but he did not expect that it was not the limit.


    It has to be said that in the Cold War era, because of the threat of war, the scientists in the Soviet Union and the Federation really applied some technologies that could have benefited mankind to how to kill the same species efficiently, and made a lot of terrible weapons.


    But it is undeniable that the Cold War era is also the era of the fastest progress of human science and technology.


    In the Cold War era, just in the field of space, the first man-made satellite was launched by the suvians in 1957, manned space flight was realized in 1961, and Gagarin, the first astronaut, went into space.


    Eight years later, in 1969, the Federation landed on the moon, marking the first time that human steps were printed on the surface of another planet. Even if it was just a satellite of a blue star, it also marked that human beings finally stepped out of their cradle for the first time.


    After that, until 1972, the Federation made six lunar landings, but in the decades after that, human beings never launched a manned spacecraft out of low earth orbit.


    Although it can be said that in the Cold War era, human beings have been living in the shadow of the end of war and even nuclear war, and even once came to the dangerous edge of the Third World War, we have to say that that era was really the era of the fastest development of human science and technology.


    The Federation has achieved unprecedented development in the aerospace field and accumulated a lot of scientific and technological strength because of vigorously promoting the Apollo moon landing program. This is also an important reason why the Federation has been able to lead the world in science and technology after the collapse of suvia.


    Space exploration is indeed a project that is difficult to see benefits in a short time. The huge amount of funds and resources required is a heavy burden even for a superpower.This also makes many people think that instead of throwing so much money into a project with no benefit and flying to the sky to dig stones, it''s better to invest the money in poor mountainous areas and buy more lunches for children.


    However, these people are short-sighted and ignore the catalysis of the development of the aerospace field to the progress of science and technology. They do not see that with the progress of science and technology in the aerospace field, it has driven the development of all industries in related fields and the improvement of technology..


    Only the progress of science and technology can make people''s life better and better. Although many people think that the rapid development of science and technology has left behind many people who can''t keep up with the speed of scientific and technological progress, this is not the reason to oppose scientific and technological progress.


    In fact, Chen Xin often thinks that if the two sides of the cold war insisted on fighting in the field of space in those years, and suvia did not fall so early, maybe human beings have colonized the moon now.


    In that case, maybe in the next few decades, many wars and disputes will not appear.


    After all, a lot of wars and disputes, in a sense, have always been around oil, an important strategic resource.


    If space science and technology can be developed by leaps and bounds, perhaps mankind will have developed new energy technologies that can replace oil, eliminate this kind of fossil energy, and adopt cleaner and more efficient energy, or even realize the scenes in the original scientific fantasy.


    If Chen Xin had only chosen to live a safe life for himself, he would not have the idea of making Titans, mobile bases, aircraft, medical cabins and so on, because there was no need for that.


    This is also intuitively reflected in the thing they are going to check and accept. For suvia at that time, although they developed this powerful machine, it did not have much practical value.


    Because at that time, the weather controller, which could only control the weather in the area with the machine as the center, could not be used as a weapon.

 Chapter 530

    Meteorological weapons are nothing new or science fiction. As early as World War II in the last century, human beings actually had the preliminary application of meteorological weapons.


    It is an early application of meteorological weapons to make the airport defog, ensure the aircraft take-off and landing, and make heavy fog to cover the troops crossing the river.


    In the real sense, the technology of artificial weather intervention appeared in the 1940s. The success of the experiment of supercooled fog nucleation and ice formation by federal scientists laid the foundation for the development of artificial weather.


    Since then, the federal government has begun to apply weather intervention technology to military experiments.


    Since 1966, the Federation has secretly conducted artificial rainfall in Vietnam for seven years to destroy traffic and cause difficulties in the mobilization of the Vietnamese people''s army and material transportation.


    The whole process is divided into two stages: test stage and actual operation stage. The test stage was carried out in Laos in 1966, and the actual operation stage was carried out in the rainy season from 1967 to 1972 in the long and narrow area at the junction of Laos, Vietnam and Cambodia.


    The operation mode is mainly to use wc-130e meteorological reconnaissance aircraft and rf-4c reconnaissance aircraft to launch smoke bombs containing silver iodide or lead iodide into cumulus clouds in the operation area. In the process of falling, the smoke bomb is ignited to produce artificial crystal nucleus to promote the cloud and rain.


    The federal artificial rainfall operation is considered to be a precedent for the use of meteorological weapons in meteorological warfare, which has become the beginning of the application of meteorological weapons to the battlefield.


    As for the term meteorological weapon, it appeared in the 1970s, and its prominent feature is strong concealment.


    Sometimes, the consequences of weather modification are mixed with natural weather changes, and the effects of weather modification at a certain time and place can only be displayed in the area far away from the target area after several hours, days or even weeks.


    It is difficult to identify the connection between this consequence and artificial influence operation, and it is easy for attackers to evade the responsibility of war initiators.


    As early as 1977, the United Nations promulgated the Convention on the prohibition of the use of means affecting climate for military purposes. In 1992, the United Nations Framework Convention on climate change once again reiterated the prohibition of the development of meteorological weapons. However, the research on Meteorological control technology by European and American military powers headed by the Federation has never stopped.


    Meteorological weapons are strategic weapons embodying the idea of total war, and have the destructive ability to compete with weapons of mass destruction such as nuclear, chemical and biological weapons. At the same time, meteorological weapons are also used in concealment, which makes it difficult for the injured country to pursue responsibility.


    Therefore, in the era of bipolar hegemony, when the Federation holds such a powerful weapon, how can suvia be willing to be threatened by the federal meteorological weapons?


    Therefore, in the most intense era of bipolar hegemony in the last century, suvia also devoted herself to the research of meteorological weapons, and achieved quite good results, and even completed a weather controller similar to that in science fiction.


    However, the weather controller has defects due to technical reasons. It can only affect the weather within a certain range with the instrument as the center, and can not influence and control the weather in a long distance. Needless to say, the cost of using it once is quite high, and a lot of preparatory work is needed.


    This also made this weather controller like chicken ribs to the suvia at that time. It was tasteless to eat and a pity to abandon.


    When the suvians started the machine several times, all they could do was adjust the weather near the capital and avoid two droughts.


    Of course, for the suvians of that era, this level of weather control was a great achievement. At least it could protect the capital from federal weather weapons.


    Moreover, the suvians are not stingy with follow-up investment, and still intend to continue to study.


    However, with the deterioration of the economic situation in the late suvia era and the final disintegration of suvia, the successor Lucia did not have enough strength to continue to promote these studies.


    The space program of the suvia era was forced to stop. Even the completed space shuttle had to give up and let it rot. a large number of scientific research institutions were unable to support and had to be dissolved. The same was true for the research on Meteorological weapons.


    The whole weather controller is sealed up together with the supporting base. Although Lucia officials wanted to restart the research several times, they were too poor to afford the funds to restart the research, and even could not maintain the sealed base.


    This also led to the fact that when Chen Xin and others came here, the gate of the base had not been opened for decades, just like the base they had been to in Siberia before.


    Looking at the dust raised after the door was opened, and the thick layer of dust on the surrounding equipment and various things, Chen Xin couldn''t help saying, "even if you don''t have money to maintain, you don''t even say you don''t do cleaning for decades, do you?""The security level here is very high. No one has been in since it was sealed up." The accompanying Lucia officials were obviously familiar with this situation for a long time. After all, when suvia disintegrated, they inherited too rich a legacy. They were used to these things and didn''t care much about them.


    In fact, both the research base and the Siberian weapon test site Chen Xin had seen before belonged to the type of sealed up and abandoned archives in warehouses for decades.


    If it wasn''t for Lucia''s leader, who was once a member of the Intelligence Department of suvia, who had a good understanding of these things and had counted the legacy of the suvia era after he came to power, I''m afraid that the existence of these things would even be forgotten. No one would remember that suvia had carried out these studies in that year.


    Chen Xin had no choice but to shake his head. He stepped on the thick dust on the ground and entered the research base to see what the weather controller made by the suvians was like.


    However, after Chen Xin entered the base, he realized that the so-called weather controller was actually the whole base through the introduction of Lucia officials nearby.


    At that time, the weather controller made by the people of suvia continued the consistent thinking and style of military weapons in suvia. After realizing the function, it was directly connected by power.


    Thanks to it, the volume of the whole weather controller is extremely huge. Although the core part is not particularly huge, its supporting equipment needs the whole base to accommodate.


    And if you want to use this weather controller once, you need a supporting nuclear power station to provide power for it. Not to mention, you also need the aircraft to broadcast relevant chemicals in the corresponding airspace in advance to enhance the effect, which is very cumbersome.


    If it''s just cumbersome steps and huge investment, which is acceptable to suvia, this weather controller can only affect the weather of its own surrounding areas, which makes subsequent Lucia officials feel that it is really a chicken.


    This also makes them willing to trade this seemingly important strategic weapon with Yanguo.

 Chapter 531

    "It hasn''t been started for decades. I''m afraid we can''t use it until we clean it thoroughly." After seeing the situation of the whole base, Chen Xin couldn''t help shaking his head.


    The whole base has been sealed up for more than 30 years, and all facilities are seriously aging. Apart from that, there is dust everywhere. There is no place for people to stand. It is a problem to check whether the weather controller can still be used even if the base is just put into operation.


    "The base will be handed over to you according to the order of the superior. If you need to clean up the base, we can provide you with the necessary manpower." Lucia official looked at the dusty place and felt that it really needed to be cleaned up.


    And to provide the people of Yan with the help they need is also the task of Lucia''s leader before he came.


    After hearing what the other party said, Chen Xin thought about it and nodded: "find some people to clean this place, please."


    "OK, I''ll arrange for people to clean up here. What else do you need?" Lucia''s officials nodded and agreed. Now there are a lot of idle manpower in the capital. They are sent to clean up the long sealed base, so as not to panic and create new troubles.


    Chen Xin shook his head: "clean up this place first. Let''s talk about it when we can use it. I''ll tell you what else we need."


    "All right." Lucia''s official was not surprised. He nodded and said nothing more.


    At this time, the commander of the reinforcement force who was responsible for protecting Chen Xin came to him and asked him, "academician Chen, what''s the use of cleaning up here? Are we going to stay here? "


    Chen Xin nodded his head and replied in a positive way: "this weather controller has very important research value. If it can change the current blue star climate and weather, and let the sun shine down again, it can greatly improve the living environment of human beings.


    Lucia has transferred the ownership of this base to us, so I will move both ark to this base later, and we will stay here temporarily.


    After that, there will be follow-up personnel in China. On the one hand, they will continue to assist Lucia and help them rebuild the capital to tide over the current crisis and difficulties. On the other hand, they will be able to study the weather controller nearby


    Speaking of this, Chen Xin stopped for a moment and asked the commander to slow down. Then he continued: "so this place will become more important. For the time being, you will be responsible for the security problem. Let the soldiers find out the situation here and guard here."


    Hearing Chen Xin say so, although he didn''t feel much about the place where the ground was covered with dust and the machines were rusted, the commander solemnly replied, "yes! Make sure you get the job done! "


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    According to Chen Xin''s expectation, after Lucia organized people to clean up the whole base, the two ark also moved here and lowered to the mooring height again.


    This base used to have a supporting airport and nuclear power plant, but now it is covered by snow, and the original nuclear power plant has been shut down since the time of suvia.


    As for why the nuclear power plant was shut down, it has a lot to do with the city cutting incident that year.


    Before the Chicheng incident, the use of nuclear energy in suvia was very extensive. It even produced such things as mobile nuclear reactors and lighthouses, which can be described as a typical case of the wide application of nuclear energy.


    However, with the meltdown of the core of the Checheng nuclear power plant and the huge disaster caused by it, suvia realized the danger of nuclear power and shut down some small nuclear facilities.


    In fact, the sealing up of this base has a lot to do with this, because the whole set of weather controller needs to consume a huge amount of electricity in the process of operation. There is no nuclear power station which can provide a lot of electricity. It is unrealistic to drive this weather controller by conventional electricity, because it needs the power supply of the whole city at that time.


    Although the site has been cleaned up, the nuclear power plant has been shut down for many years, and the reactor has been buried in snow and frozen to death. So even if the base is cleaned up, it will still be in the same state as a big ice cellar for a while and a half, and the water and electricity will not be restored.


    However, it was only a small problem. After all the others arrived, Chen Xin arranged for others to settle in the base and began to put the base back into operation.


    "Academician Chen, at present, what we need to solve most is the problem of power supply and material supply." The captain of the Haizhu put forward his own views to Chen Xin on how to re operate the base, and explained to him: "although we are carrying sufficient supplies at present, if we want to stay for a long time, this material is not enough to consume.Although lucians said they would provide some help for us, they don''t have much spare power now. If they only rely on domestic transportation, they certainly can''t! So for the sake of long-term stationing, we must be self reliant and self-sufficient here. "


    "I agree with that. I suggest opening up several greenhouses in the base, planting a little vegetables and grain to reduce the supply pressure." The captain of the Xugou also agreed, and wanted to play the glorious tradition of the Yan army in Lucia.


    Chen Xin naturally would not object to this, but he also pointed out to the two: "it is necessary to achieve self-sufficiency in material supply, of course, but the first thing we need to solve is the problem of electricity. Without electricity, even if the greenhouse is built, it is useless."


    Hearing what Chen Xin said, the two captains couldn''t help nodding.


    "Academician Chen, how do you plan to solve this problem? Restart the Lucian nuclear power plant? " The captain of Haizhu has read the relevant information of the base, and naturally thought of the nuclear reactor that was shut down in the suvia era.


    "That reactor was built in the era of suvia, and it was shut down when suvia disintegrated. Now it''s almost impossible to repair it." Chen Xin shook his head and denied the possibility: "my plan is to build a large isotope generator here to replace the nuclear reactor to provide power for the whole base."


    In fact, Chen Xin has a better way to solve the problem of power supply, that is to build a fusion reactor directly, but controllable nuclear fusion technology is of great significance after all.


    Building a fusion reactor on a foreign land is really too influential. Considering that the senior management may not agree, Chen Xin plans to build a large isotope generator here.

 Chapter 532

    As for the weather controller, China also attaches great importance to it. It not only provides Chen Xin with follow-up supplies and the large isotope generator he needs, but also uses several new helicopters to lift a mobile base.


    Of course, the latter is Chen Xin''s additional request.


    In fact, for the country, although the weather controller has a certain significance, it is not worth investing so much energy and so many materials.


    In particular, a mobile base can be hoisted from Yanguo to Lucia by helicopter. Even if the domestic helicopter has been upgraded, it can do such a thing. It is also a huge loss for these helicopters to fly down thousands of kilometers with hundreds of tons of load.


    After all, the weather controller is only a product of the suvia era. Compared with the modern technology of artificial weather intervention, it is largely an outdated technology.


    Lucians can use it as a bargaining chip in exchange for follow-up aid from the Republic of Korea. After all, it''s all the black technology of the suvian era. Even in modern times, it still has a certain reference value.


    But to say how much attention the country attaches to weather controllers is to say that it looks up at them.


    For the suvians in those days, the weather controller was chicken ribs. Now, for the people of Yan, it''s also chicken ribs.


    The whole weather controller is a whole base. It can''t be moved, and it''s still near the capital of Lucia. The scope of influence is limited to the area where the weather controller is located. It doesn''t play any role in Yanguo.


    So send someone to study it, get the technology, refer to this technology after returning home, and copy a more advanced weather controller, which is the normal way to deal with it.


    However, Chen Xin is responsible for handling the weather controller. Naturally, he has a completely different view on this thing.


    In other words, Chen Xin, who holds the system in hand, does not need to study the technology of the weather controller in a conventional way. He can completely improve the weather controller by upgrading the system, and give full play to its role.


    After all, the weather controller affects the weather. After upgrading, it can control the weather, even the climate.


    According to Chen Xin''s idea, if this thing can be upgraded continuously, it will be used by him to transform the planet''s environment, accelerate the speed of natural recovery, and correct the current environment of the blue star back before the meteorite impact.


    However, this is not an easy thing to do. Although Chen Xin has always had such an idea before, it''s a pity that he lacks the necessary foundation, so that this idea has always stayed in the stage of just thinking.


    However, with the weather controller, Chen Xin has the foundation to upgrade. As long as he keeps upgrading the weather controller, sooner or later, he can upgrade it to a super existence that can directly modify the planet''s climate.


    Chen Xinke still remembers the blue cat new theater version he saw before the meteorite impact. In the dinosaur era, after the meteorite impact, there was dust all over the sky, and it set off a terrible fire shock wave.


    However, the black technology pulled out by the blue cat made a hole in the dust and falling meteorite, allowing the sun to shine down. Relying on the weather control of the black technology, the impact and dust were completely ineffective, sheltering the island where dinosaurs lived.


    If Chen Xin can upgrade the weather controller to that level, transform the global climate, and let the blue star return to the environment before the disaster, it is not impossible.


    Of course, this also means that Chen Xin needs to invest a huge amount of survival to upgrade the weather controller, and it can not be upgraded in place at one time, but needs to be upgraded again and again.


    Therefore, it is the most appropriate solution for Chen Xin to occupy the base where the weather controller is stored, and then slowly upgrade and transform the weather controller here until he finally realizes his vision and purpose.


    However, Chen Xin does not have the idea of living in Lucia for a long time. Although the weather controller is very important, it is not worth spending a lot of time in Lucia.


    After all, such an important thing, or move back to their own home in order to be reassuring.


    This is also the reason why Chen Xin asked China to transport a mobile base. He plans to upgrade the whole weather controller and try to reduce its size, then transfer it to mobile and ground, and then use the mobile base to transport the weather controller back to China.


    Although it is a bit troublesome, it is just right for Chen Xin to do so.


    And the weather controller installed on the mobile base can perfectly solve the problem that the weather controller can only affect the weather around itself.


    It may be difficult for the weather controller to control the weather in other areas at will, but it is not so troublesome for the weather controller itself to move.As for reducing the size of the weather controller or something, this is even simpler.


    Chen Xin has read the information provided by the lucians. The reason why the suvians made the weather controller so large in those years was mainly due to technical problems. Many parts were limited by the materials and machining accuracy at that time. They had to be made so large to achieve the purpose of controlling the weather.


    But for modern science and technology, half a century ago things are really behind. It''s not very difficult to improve technology and reduce volume.


    What''s more, Chen Xin still plans to use the system to upgrade the weather controller, so that the size of the machine can be reduced. At that time, he only needs to use the mobile base to transport the weather controller to the place where it needs to be, and then start the machine, so as to realize the maximum use of the weather controller and change the climate of the target area, It''s not just used to adjust the climate of a certain area.


    Of course, all this requires time and a lot of resources.


    China has given Chen Xin a lot of support in this matter. Although it can not be said that Chen Xin has spared no effort.


    The main reason for the state''s support for Chen Xin lies in its trust in him. After all, Chen Xin has indeed made a lot of contributions to the country and has shown great ability.


    Therefore, the state is willing to believe in his ability and provide support for him in such matters.


    So for this matter, Chen Xin still hopes to do it well, although there is no problem for him to do it well.


    With the material support provided by China, the base built by the suvians was once again busy.


    The large isotope generators were assembled and connected to the power supply lines of the base, which restored power supply to the dusty base once again.


    And after having electric power, Chen Xin and their work also started formally.

 Chapter 533

    With the power supply, the whole base will naturally run completely.


    Although many places have many faults due to disrepair, they were solved one by one with the efforts of Yanguo staff, making the whole base run smoothly.


    It''s just that we are not used to the use of this suvia base.


    "Academician Chen, at present, the base has resumed operation, but many of the equipment are old objects from the suvian era of the last century and can only barely make do with it." In the conference room of the suvia era, the captain of the Xu dog was reporting to Chen Xin.


    This conference room still retains the decoration of the suvian era, and the portraits of revolutionary tutors and iron and steel comrades are still hanging on the walls, which is very reminiscent of that era.


    For lucians, they may not be used to this style, and even a lot of people will express disgust. But for Yan people, it''s no surprise. Some elderly people even feel friendly, so they didn''t take the two portraits away when they cleaned up.


    However, the decoration can be preserved, but the equipment can not.


    Many of these portraits were hand drawn by painters of that era. Although they are not famous paintings now, they are also worth a little money.


    Even before the disaster, printed matter was something that some suvian collectors liked very much. The longer it was put, the more valuable it was.


    However, many of those circuits, equipment and instruments have been rusted. It took decades to rust the most advanced instruments into a pile of scrap iron.


    What''s more, even the most advanced instruments and equipment at that time are basically eliminated today.


    After repairing, they can still make do with it, but those things are really inconvenient for people to use, which leads to Chen Xin''s problem now is these old equipment.


    It''s unrealistic for others to replace all the new ones. After all, even if the equipment is transported from China, the state is willing to support it. It''s not worthwhile.


    As for the support from Lucia, if they have the ability, how can they let this base be abandoned for so long.


    However, this is the best problem for Chen xinlai to solve. After listening to the report of the captain Xu dog, he nodded slightly, thought about it, and said, "I have expected this. Later, I will transform these old equipment. Don''t worry about this. There will be usable equipment."


    Hearing Chen Xin say so, other people did not raise any objection, just nodded and went to the next topic.


    "The experts and the rescue team have moved into the base. We plan to demarcate an area for the treatment of infected people and the follow-up study of the virus. Fortunately, there are many empty places in the base. We have sorted out an area ourselves, and we are almost ready now." The team leader of the expert group explained to Chen Xin their work during this period, and it was a happy thing for them to continue to carry out research on the virus.


    It''s just that although we can continue to work, the problem is not without it.


    The leader of the expert group complained to Chen Xin: "it''s just that the rooms here don''t meet the requirements of asepsis. We can''t build the negative pressure ward for a while and a half. What''s more important is that the medical cabin you brought with you, academician Chen, has been sent back to China. Now it''s very difficult for us to carry out the treatment work for the patients with severe infection and the patients with variant infection."


    Although the "zombie" was cured before, the medical cabin had already returned to China with the aircraft carrying virus samples at the time of the attack. Now the expert group really can''t come up with any good method to treat the "zombie" mutation infected people.


    Although it is said that the support therapy to enhance human immunity can resist the erosion of the virus on the human body, but there are limits.


    The immune system of patients with mild and moderate diseases has not been greatly damaged. With medical support, they can continue to fight against the virus and eventually expel the virus from the human body.


    However, the body of the patients with severe infection and mutated infection has already become full of holes, and the immune system has almost collapsed. In this case, even if there is medical support, it can only maintain life, so that the situation does not worsen.


    If there is no specific drug for this virus, these severe infections and mutated infections can basically be said to have been unable to save.


    For this problem, the leader of the expert group certainly hopes to send the medical cabin back, but he has no authority to make a decision on this matter, so he can only report it to Chen Xin for him to solve.


    Chen Xin nodded, this matter is easy to solve, he still has the authority to transfer the medical cabin back.


    "I''ll take care of the medical cabin, and I''ll leave the treatment of the infected to you." Chen Xin said to the team leader, but also turned his eyes to other people: "the state has promised to help Lucia carry out the reconstruction work. The treatment of infected people is one of the most important parts of the whole reconstruction work, and other aspects of the work will be carried out one after another.We will be an important base for the state to assist Lucia. After that, the domestic materials, personnel and other assistance will arrive at us first. Therefore, in addition to our current work, the whole base should also make preparations in this regard. "


    "Will there be massive domestic aid for Lucia?" The captain of the Haizhu asked Chen Xin how much assistance China would provide, which also determined how large-scale preparations they would make.


    "At present, China will provide a certain amount of material assistance, but the scale will not be too large. After all, the transportation capacity is limited. Moreover, the previous earthquake in Southwest China consumed a lot of national reserve resources, and the support to Lucia is also very limited." Chen Xin shook his head. He also communicated with China on this point and got the answer that China would not provide large-scale support for Lucia''s materials, and the assistance mainly focused on technology.


    In fact, it''s not that China is stingy of material support, but that there are no conditions for it.


    After the great earthquake in Southwest China, all the major domestic forces have been used for the resettlement and reconstruction of the disaster areas in Southwest China, and all the materials have been transported to southwest China as much as possible, which is beyond Lucia''s reach.


    Therefore, after some discussion, the domestic assistance that can be provided to Lucia is mainly technical.


    Chen Xin is very understanding and supportive of such a decision made at home. After all, his own problems have not been solved. How can he spare so much energy to manage foreign countries.


    However, since we have taken so many things from Lucia, we can help them as much as we can. After all, in this situation, fighting alone will only make us in a difficult situation. Only by working together can we better rebuild our home.

 Chapter 534

    However, although Yanguo agreed to continue to assist Lucia, the situation in the capital of Lucia is still not optimistic.


    Although the oligarchs behind the scenes have been suppressed, and all kinds of unrest in the capital have been suppressed by the troops stationed in the capital, the relationship between the revolutionary army and the government has also dropped to the freezing point. Although there is no conflict between the two, there is nothing more.


    After all, the two were still hostile before. Although the two sides temporarily reached an agreement to stop the struggle and jointly deal with the spread of the disease because of the epidemic and the mutated virus, the oligarchs'' rebellion destroyed the hard won fragile peace.


    Now the official Army has suppressed all the unrest and stabilized the situation in the capital for the time being, but behind the calm, there is still undercurrent.


    Most of the people in the revolutionary army were awed by the force shown by the official, and for a moment they really did not have the courage to confront the official.


    But correspondingly, the vast majority of the people in the revolutionary army have become restless.


    After all, the strength of the official Army means that it is not difficult for them to level off the enemy revolutionary army.


    This is not only the bottom line, but also the top level of the revolutionary army.


    At this moment, they deeply realize that revolution is not as easy as they think. It can not be called revolution just by standing up and shouting slogans and taking people to attack official facilities.


    Moreover, if the revolution wants to succeed, it needs to face not the decadence that can be easily pushed down, but the invincible enemy that needs to experience arduous struggle.


    If we want to really win the revolution, we need the courage and perseverance of the real revolutionaries.


    But these two points are not available to the so-called "revolutionaries" of the Revolutionary Committee. Many of them have even begun to think about capitulating to the authorities.


    Dalia naturally sees all this in her eyes, but she has no good way to break the present situation.


    Although she found a lot of revolutionary works according to the old Bolshevik''s suggestion and drew a lot of valuable knowledge from them, she was still immature and lack of exercise.


    Although she has some awareness that a real revolutionary should have, she is still far away from a real revolutionary.


    At least in terms of revolutionary will, Dalia is still lacking, because even she is shaken when she sees the official Army suppressing the oligarch armed forces.


    Can their so-called revolution really succeed? Do they have the ability to defeat the official Army in front of them, overthrow the official rule and build a new country?


    Naturally, the answer is self-evident.


    "Let''s talk about it. You can say anything you want to say. In the face of the current situation, you can say what you think." Dalia looked at all the members of the meeting, felt the dull atmosphere of the meeting, and motioned for everyone to speak.


    However, no one came forward.


    At this time, Dalia deeply understood why the old Bolshevik would say that they were not real revolutionaries, but just children.


    In the face of the strength of the enemy, they did not have the courage to face the difficulties as their predecessors did, nor did they have the determination to open up victory with their flesh and blood, nor did they have the faith and perseverance to overcome all difficulties and obstacles.


    Dalia knew that many of the members of the committee had been scared out of their wits, and even thought about how to surrender to the authorities, so as to keep their insignificant power and status.


    She couldn''t help feeling very sad for these people.


    In the past, they complained about the government and felt that the suffering of life was brought by the government, because the government did not give them a good life.


    Dalia once thought the same way. After all, Lucia''s life was really hard in the past. We all wanted to find a sustenance because we couldn''t see hope in life.


    Revolution used to be just a word they talked about and a channel for them to vent their depression. All of them, including Dalia herself, never thought that they would succeed in revolution and realize their so-called "ideals" one day.


    But when the tide surging, opportunities appear in front of them, the tide swept them to the present position, they can not help but have an unreal feeling.


    This kind of untruth leads to that they are not ready to face all this, and they have no ability to deal with the problems they encounter.


    "We don''t have to be so pessimistic." Finally someone broke the silence. Dalia looked around and said that it was wa Lianjing, who had been regarded as a capitulator."Of course, you don''t have to be pessimistic. Anyway, for you, you just have to surrender!" Perhaps due to the influence of inherent impression, even though he has proved that he is not a capitulationist before, some people still regard him as a coward in the revolutionary team.


    However, walianjing didn''t care about this kind of evaluation. He went to the podium and looked at all the people in the conference room with firm eyes and said, "we still have hope, not surrender, but try to strengthen ourselves."


    Dalia looked at walianjing and was surprised at what he said, so she asked, "walianjing, why do you say that?"


    "I know that everyone is afraid of the strength of the official Army, but this is not what we need to face now." In fact, walianjing''s belief has always been firm. He always insists on doing what he thinks is right. In this regard, he seems to be more like a qualified revolutionary than other members of the Committee.


    His words aroused the interest of others.


    Seeing that everyone''s eyes turned to him, WA Lianjing continued to explain: "in fact, the authorities can take advantage of the aftereffect of sweeping down the oligarchic armed forces to defeat us, but they did not do so. Why? Because they don''t dare! "


    Such a bold argument caused a commotion in the conference room. We all listened to what wa Lianjing said more seriously. We wanted to hear why he said it and what the basis was.


    After all, the current situation has been so bad, any possible hope is good, they are eager to seize the last straw.


    "Now the environment is too bad, not only for us, but also for them! If conflicts and wars break out between the official Army and us in the capital again, the whole capital will be destroyed, and even the official will not be able to rebuild their homes in the cold ice and snow to save the situation! So they dare not fight! " Wa Lianjing emphasized loudly, and his words seemed to inject courage into everyone in the meeting room.


    Dalia''s eyes lit up, too. This statement of wa Lianjing is very reasonable. She couldn''t help asking wa Lianjing, "what should we do?"


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 535

    The answer given by wa Lianjing is to cooperate with Yanguo.


    Although the revolutionary army is awed by the combat effectiveness of the official Army, what is hidden in its heart is more dissatisfaction with the official Army.


    We have a strong army, but we can''t solve the epidemic. We don''t use the army to protect the people, but to suppress the riots


    How can it be without public resentment?


    People in the revolutionary committee actually know this, which is why no one has proposed to surrender.


    On the one hand, they are reluctant to give up their present power and status, although it is only a trivial thing.


    On the other hand, surrender is not supported by the people. If they dare to declare surrender, they will be overturned by the angry people at the first time.


    After all, it''s one thing to be deterred by the official force and lose the courage to resist the official. It''s another thing to surrender to the official and give up resistance.


    Under such circumstances, there are naturally not many roads to choose before the Committee.


    And to cooperate with Yanguo is a practical way for the current revolutionary army.


    Under the condition that the officials dare not continue to wage war to destroy the capital, the revolutionary army is not in danger of being exterminated, provided that they do not die themselves.


    As for what to do next without the threat of life and death, if we can''t think of it at all, there is no need for the revolutionary army to continue to exist.


    The reason why wa Lianjing proposed to cooperate with Yanguo is that, as one of the few clear headed and far sighted people in the committee, he understands that it is absolutely impossible to develop the revolutionary army by itself.


    After all, this is not the past. Even if they occupy more than half of the city, without material output, it is difficult to support the operation of the city and the development of the revolutionary army.


    After all, the capital of Lucia is different from that of Yan state. Although there are also a large number of underground air raid shelters and refuges, most of them were built in the suvian era to deal with the possible nuclear war with the Federation.


    When it was first built, it was not considered to grow vegetables underground.


    Unlike the Yanks, who like to grow things everywhere, the lucians prefer to store enough materials.


    Of course, they are not short-sighted. They really don''t grow anything, but the harsh and harsh natural environment makes Lucia''s agriculture less developed, and even more so now.


    If it wasn''t for Lucia''s vast territory and small population, there would be no good way for her to support so many people.


    In fact, even if the official Army does not manage the revolutionary army, they will soon face a serious problem, that is, food shortage.


    Under such circumstances, there are only two ways for the revolutionary army to develop.


    Either cooperate with the government or with the government.


    In the case of internal emotions against the official, the only thing the revolutionary army can choose is to cooperate with Yanguo.


    As for their own independent development, I''m sorry, they don''t have that ability.


    Because of this, Dalia, after thinking about it, sent walianjing and Vasili as representatives to discuss cooperation with Yan people.


    As for the revolutionary army, Chen Xin decided to meet them after some consideration.


    Vasili and walianjing have been discussing how to persuade Yanguo to agree to help the revolutionary army on their way here. However, when they entered the base cleaned up by Yanguo people, they were shocked by what Yanguo people had done.


    The whole base has now been cleaned up, and all water and electricity facilities have been maintained. It has been upgraded from the decadent and dilapidated suvia era to the modern level, and a new temporary planting greenhouse has been built in the base.


    It can be said that in such a short period of time from the time when Yan state obtained the ownership of the base to the time when Vasili and walianjing came here, Yan state has completely transformed it into a base that can live, live and work, and can also maintain itself and produce food.


    Vasili and Vasili were just passing by the greenhouse that had been built and was planting seeds when they entered the base, which made them very envious.


    As the top leaders of the revolutionary army, they certainly know that Yan won the base after the official Army suppressed the oligarchs. It''s not a few days, and even the battlefield has not been cleaned up yet. However, Yan people have already settled the whole base. Vasili and walianjing are shocked and even frightened by such executive power.After all, Yanguo people were able to deal with everything in such a short period of time, and even build greenhouses. In addition to Yanguo people''s strong infrastructure capacity, more importantly, Chen Xin upgraded the whole base.


    Because the whole base is only upgraded from the old state of the suvia era to the modern level, and the most core weather controller is not activated, so the cost of survival is not much, and the upgrade of the whole base is not exaggeration, just equivalent to a maintenance update.


    Because of the vague concept of system, Yan people didn''t find it strange, but for two lucians, this kind of thing is too exaggerated.


    Lucia''s infrastructure capacity and work efficiency under normal conditions are far less than that of Yan country. Therefore, even the normal construction speed of Yan country is enough to surprise lucians, not to mention the speed of Chen Xin''s opening and hanging.


    This also makes when Vasili and Vasili come to the meeting room to meet Chen Xin, the expressions on their faces are eager and expectant.


    After all, if the Yan people have such a strong construction capacity, they can help the revolutionary army build their own homes and make it possible for them to develop as long as they are willing to help.


    However, when Vasili and walianjing made clear their intention to Chen Xin, and proposed that they wanted to cooperate with Yan state in exchange for Yan state''s request for help to the revolutionary army, Chen Xin refused.


    "Why?" Vassili was puzzled, but also had some grievances and complaints in his heart. Yan people have such a powerful force, why don''t they want to help us? Isn''t it true that Yan people are very enthusiastic and helpful?


    Vasili''s question was also what Vasili wanted to ask, but he was relatively more official and did not ask the question.


    But now he is also very concerned about looking at Chen Xin, hoping to hear the answer from him. After all, he can continue to think of other ways to persuade Chen Xin.


    However, Chen Xin gave a reply that they did not know what to do: "what can you offer in exchange for our help? The official use of this base as a price in exchange for us to continue to help Lucia. What about your revolutionary army? What can you come up with? "

 Chapter 536

    Chen Xin''s words are extremely straightforward, which makes Vasili and wa Lianjing turn pale. They want to say something, but they can''t say anything.


    In fact, as Chen Xin said, Yan state can help the official of Lucia, and also obtain from the official all kinds of technology and heritage that can make Yan state interested. What can the revolutionary army do in exchange for Yan state''s help?


    If the former oligarchs had not been suppressed by the government and were willing to help the revolutionary army from behind the scenes, maybe they could come up with something that would interest Yanguo to persuade Yanguo to agree to help the revolutionary army.


    But now the oligarchs in the revolutionary forces have been suppressed by the government, and their forces have been uprooted. Even if there are still potential oligarchs, their power has not been able to turn over big waves.


    So even if they have something in their hands that can interest Yanguo, it won''t come out at this time, and it will attract the official attention and suppression.


    Vasili and walien Kyoto knew this clearly. They thought hard for a long time, but they found that although the huge revolutionary army occupied most of the capital city of Lucia, they were poor and had no chips to fight for the help of Yanguo.


    Looking at Vasili and walianjing''s changing faces, Chen Xin shook his head with a smile and said to them, "if you are really for the good of the people, I suggest that you don''t think about making trouble, but cooperate with the government to rebuild your capital.


    In this cold weather, you are short of food and clothing. If you destroy the only shelter that can keep out the wind and snow, do you want everyone to freeze to death?


    Now for you, it is secondary to be revolutionary or not. What you should do now is to let your people free from this epidemic and live a good life again. "


    "But..." wa Lianjing wanted to explain, but before he spoke, he was held by Vasili.


    "Don''t say it, walianjing." Vasili shook his head at Vasili and stopped him from saying, "he''s right. If we can''t make the people live better, why should the people follow us?"


    Of course, walianjing understood Vasili''s words, but he didn''t want to give up and said, "but if we can''t get help, what can we do to improve people''s lives and make them live better?"


    With that, WA Lianjing looked at Chen Xin again and said to him stubbornly: "Mr. Yan Guo, since you are willing to see us, I believe you are not going to refuse to help us directly. You said you need to pay for Yan Guo''s help, which proves that you already have a price in your heart, so can you tell us what you want? We are willing to pay the price as long as we can get the help of Yanguo and make the people live better. "


    Wa Lianjing thinks that he has guessed Chen Xin''s real purpose. He also thinks that his words are enough to move Chen Xin and make him ask for a price.


    In wa Lianjing''s view, as long as Chen Xin is willing to make an offer, everything will be discussed.


    No matter how much Chen Xin has offered, the revolutionary army must promise whenever it can afford it, because only in this way can the revolutionary army get the chance to develop and carry on their revolutionary cause.


    However, Chen Xin directly shook his head and said to wa Lianjing, "Yan country is not interested in your so-called revolutionary army. In fact, we are more willing to cooperate with Lucia officials than you. This is not only because the officials can afford to cooperate, but also because they still control most of the country.


    Although you now control most of the capital, you have nothing else. As long as the epidemic problem can be solved, the authorities will be able to stabilize the situation quickly. I don''t need to explain what will happen next to you


    Chen Xin''s words let walianjing and Vasili do not know what to say, can only be silent.


    Looking at their silence, Chen Xin shook his head and said to them, "in fact, I don''t think you need to adhere to your so-called revolutionary ideal, because it''s not a revolution at all.


    The real revolution means that the old society has been decayed and needs to overthrow the old order to complete social change. However, although there are some problems in your old order, it is not decadent and needs to be overthrown.


    For you, instead of thinking about how to make a revolution and how to develop your revolutionary army, you should think about how to cooperate with the government to rebuild your capital so that your people can have enough to eat and not suffer from hunger and cold.


    So go back, go back and tell your comrades, let them not think about confrontation, cooperate with the government, make concerted efforts to rebuild your capital, and let everyone live a life free from hunger and cold. That''s what you should do.


    We have reached a cooperation agreement with the government, which will help you rebuild the capital. There will be a lot of places that need labor. The manpower in your hands is still very important for the reconstruction work. Therefore, instead of saying something meaningless to me here, you''d better go back and think about how to cooperate with the government. "Although Chen Xin''s words sounded harsh, they were very pertinent suggestions for the revolutionary army at that time.


    At this time, no matter what conditions the revolutionary army can offer, it is not enough to persuade the high-level officials of Yanguo to agree to support a new regime to overthrow Lucia''s existing regime.


    In fact, the first batch of aid has already been prepared in China, mainly experts in geothermal and greenhouse cultivation, who will help lucians build a geothermal energy tower in their capital and use this tower as energy to build a large-scale greenhouse for cultivation.


    In addition, there will be an engineering team to follow. In addition to the construction, it will also help the lucians clean up the damaged shelters and repair them.


    Although the aid is not much, but for Lucia, it is urgently needed.


    The energy tower can provide them with warmth and solve the problem of fuel shortage under the pressure of cold environment. Although it takes a certain amount of time to grow crops in the greenhouse, it can also solve the problem of food shortage faced by the capital of Lucia.


    As long as there is enough time to solve the current epidemic problem, the reconstruction of Lucia is not a problem.


    So Chen Xin didn''t pay too much attention to this matter. After he dismissed Vasili and wa Lianjing, Chen Xin turned the focus of his work back to the weather controller that had been cleaned up.


    He didn''t forget what he was staying for.

 Chapter 537

    In fact, weather control is not very difficult, its basic principle is not complex.


    For example, artificial rainfall, which is now one of the most common technologies, is actually the most intuitive application of weather control.


    However, limited by the existing human technology level and the scale of related investment, it is very difficult to achieve artificial weather intervention.


    As long as junior high school geography class did not sleep in, basically all know the formation of the weather, the main reason is the temperature, there are differences in temperature in different regions, hot air flows to cold air to form the wind; The hot air evaporates the water vapor on the ground, and the water vapor condenses when encountering the cold air, which becomes precipitation


    In the final analysis, the main reason for the weather on the blue star is the solar radiation, because the energy brought by the solar radiation and the evaporation of surface water form all kinds of weather.


    So artificial intervention or manipulation of the weather, as long as the temperature is controlled, can actually affect the formation of a lot of weather.


    For example, if the local air is heated to above zero, the snowstorm can be turned into heavy rainfall, and the wind direction can be adjusted by controlling the location of the heating area.


    In fact, a long time ago, someone proposed to detonate hydrogen bombs in tropical areas to prevent the formation of typhoons. However, this method is too impractical and impractical. No country has ever really tried it.


    But when the suvians were studying weather controllers, they tried some bold ideas.


    Most of these ideas are not possible, either too much investment or technology is difficult to achieve, but there are also some ideas that can be achieved.


    Weather controller is one of the most feasible ideas, and it became a reality after the great efforts of the suvians at that time.


    It''s just that this technology needs to consume a lot of electricity, not to mention that when it is used, it also needs to send out airplanes to spread special chemicals. Both the cost and the impact on the environment were very serious at that time.


    Even as a superpower, suvia didn''t care much about this, and gave up the idea of large-scale application of this technology. It only carried out several experiments, and then asked scientists to continue relevant research without further experiments. It was not until the disintegration of suvia that the whole project was sealed up.


    Now Yanguo people have taken over this project. Theoretically speaking, Yanguo does not have the capital to apply this technology on a large scale. Especially in this end of life environment, even Yanguo can not afford to restart an experiment.


    Fortunately, it was Chen Xin who took over the project. After understanding the basic principle and operation mode of the technology, he was ready to upgrade the equipment and optimize the technology.


    The principle of the weather controller is not complicated. The equipment itself is actually a super high power microwave transmitter. Through the microwave of different bands, it can affect the formation and dissipation speed of the cloud in the region, and control the rise and fall of the regional temperature, so as to achieve the purpose of influencing the weather.


    However, although the suvians realized this technology at that time, limited by the power of the microwave transmitter and the influence of various other factors, their influence on the weather was very limited.


    Therefore, it is necessary to cooperate with the corresponding chemicals to amplify this effect and realize the real effect of controlling the weather.


    Because of this, the influence range of this weather controller is limited, and it can only work within the influence range of microwave.


    And clear the principle of this machine, for Chen Xin, upgrading is not a problem.


    First of all, of course, the first point is to improve the launch power of this machine, at least to enable it to significantly affect the weather without using chemicals.


    This is not to say that Chen Xin can''t afford to spread chemicals, but he thinks it''s too troublesome. In this environment, it''s not an easy job for planes to take off and spread chemicals. Therefore, it''s necessary to reduce the cost.


    As for how far the machine can affect, this is not Chen Xin''s main concern.


    After all, the ultimate goal is to put the weather controller on the mobile base and drag it around. As long as the influence range is not too small, it can affect the weather of the region.


    Therefore, instead of expanding the scope of influence of the machine, it is better to consider how to reduce the weight of this super large microwave transmitter which covers an area of the whole base.


    Chen Xin alone can only rely on the omnipotent system in this respect, but fortunately, there are a group of professionals around him.


    Standing near the microwave transmitter, the core of the weather controller, Chen Xin asked the people beside him, "do you have any ideas on how to reduce the volume of this weather controller?"


    These are some technicians from China who are responsible for assisting Chen Xin to complete the maintenance and upgrade of this weather controller.Facing Chen Xin''s inquiry, one of the technicians opened his own notebook and reported to Chen Xinhui: "at present, the materials used in this machine are very old. If we can replace some of the materials and optimize the structure, we can greatly reduce its weight."


    "Very good. Then you can give me a specific plan to see which parts need to be replaced and which parts need to be optimized." Chen Xin gave the job to these technicians.


    "I know, academician. We will work out a plan later." The technician answered, but he still asked Chen Xin, "academician, isn''t our main job to make this machine work? Now this machine can''t be used, and we haven''t found out its specific operation mode. Do we have to consider reducing the volume? "


    To this question, Chen Xin just replied with a smile: "it takes a lot of power to start this machine. We only have one isotope generator. Although we can supply energy to the weather controller, it''s still too wasteful to do that.


    And we don''t have the necessary chemicals to spread, even if we start this weather controller, it''s difficult to play a big role in such a bad environment.


    So in my opinion, we should first optimize and upgrade this machine, improve its efficiency, and then consider specific experiments. "


    "Is that so? But would that be a problem? " The technicians are still a little worried. Before they know the prototype clearly, they will consider improving it. This really makes him uneasy.


    However, Chen Xin was full of confidence in this, and said to the technician, "don''t worry, we have got all the original experimental records and relevant technical data of the suvians. There will be no problem."

 Chapter 538

    The efficiency of the technicians was very fast. Although they spent some time getting familiar with the structure of the weather controller, they quickly put out a plan and handed it to Chen Xin.


    The main content of this scheme is how to replace the parts on the weather controller to reduce its volume and weight.


    Although the suvians put a lot of effort and resources into this machine in those days, they were not stingy in terms of manpower and material resources, and they used the best things of the year.


    But nearly half a century later, whether it''s material or structure, many things on this machine are inevitably out of date.


    After Chen Xin got the report and went through it carefully, he had a comprehensive understanding of the parts of the whole weather controller that needed to be replaced.


    So, the next step is to upgrade the weather controller.


    However, Chen Xin''s upgrade this time is not limited to the weather controller. He also needs to adjust the building structure of the base.


    Because before the construction of the base, the suvians built it around the weather controller, which led to many buildings in the base need to accommodate the weather controller in structure.


    Now that Chen Xin has adjusted the structure of the weather controller, naturally the corresponding building structure also needs to be adjusted together.


    Besides, the base had no other functions before, but now it is regarded as a base for the follow-up support to Lucia, so it is necessary to expand its functions.


    Chen Xin has already asked people to do a good job in the relevant planning. He just needs to integrate them together when upgrading. So this time, his upgrade of weather controller also includes the upgrade of the base itself.


    It''s still the familiar green light, the whole base has changed again, but it''s still unknown.


    To be honest, Chen Xin has used the system upgrade function too many times since he got the system. It has to be said that this is the most powerful and black technology thing he has ever encountered.


    Perhaps there is a high latitude civilization behind this. Chen Xin occasionally wondered whether he should explore the existence of this civilization.


    But when he had this idea, he soon dismissed it by himself.


    It''s not because of other reasons, but because Chen Xin thinks that human beings are not qualified to explore the existence of high latitude.


    A civilization on the verge of destruction, even its own parent star has not yet stepped out, what qualifications to pursue the existence that has crossed the dimensions?


    The gap between the two is just like the gap between the people who draw on paper and the little people who are drawn on paper.


    No one has ever heard that people drawn on paper can really appear in reality, influence and interfere in the occurrence of real things.


    Therefore, even if Chen Xin really wants to explore the high-dimensional civilization behind the system, it is also a matter that he can only think about.


    However, Chen Xin sometimes can''t help thinking, is this disaster affecting the whole world and mankind just a game of high-dimensional civilization, just to see the struggle of mankind under the disaster?


    After all, the system came to the blue star with the meteorite at that time, which made it impossible for Chen Xin not to associate with it.


    But even if things really are like this, it is meaningless, because for human beings, they have to do their best to survive, even if they are regarded as the object of game entertainment by others, what can they do?


    Holding up the rebellious sword to heaven to kill the high gods also needs enough strength.


    For today''s human beings, if there are so-called gods or high-dimensional civilization, the most appropriate way for human beings is to please the gods. Perhaps the gods will give human protection and directly solve the disaster, so that human civilization can continue.


    Chen Xin doesn''t know what role he plays in this, but at least he knows that he holds the system. For human beings, maybe he is the key to ending this disaster.


    For Chen Xin himself, to end the disaster and upgrade the weather controller to a planetary reformer is the best solution Chen Xin can think of.


    But it really needs a lot of survival points. Even though Chen Xin has improved many people''s lives by promoting various technologies in China and can get a lot of survival points every day, it is difficult to support the survival points paid for upgrading this level.


    Maybe I should think about how to get more survival?


    Walking in the upgraded base, Chen Xin is thinking about this problem while checking the status of the upgraded weather controller.


    At present, Lucia''s side is an opportunity. The systematic way to obtain survival and improve the living conditions of others is not limited to Yan people.Although Yanguo has a large population, which is the best way for Chen Xin to get survival, and he does get a large number of survival from Yanguo, it does not mean that he can only get survival from Yanguo.


    To help lucians rebuild their capital is an agreement already reached between Yan state and Lucia. According to the aid agreement, it will provide Lucia with a lot of things developed by Chen Xin, so that lucians can also provide survival for Chen Xin.


    Therefore, if Chen Xin intervenes at this time, it will only make the survival that can be obtained more.


    Thinking of this, Chen Xin decided to change his original plan.


    According to his original idea, he stayed in Lucia just to upgrade the weather controller and transport it back to the mobile base. But now, he may be able to provide some help for lucians to improve their living conditions and gain more survival.


    As for how to help lucians, it''s also very simple. Now lucians need help in all aspects. Chen Xin only needs a little help, that is, a large amount of survival income.


    Although this is only a fraction of his final plan to upgrade the planet reformer, the increase in daily survival points is once and for all.


    After all, when Chen Xin tried to upgrade, the system showed that the number of points needed to upgrade was too much. According to Chen Xin''s estimation, even before the impact of the meteorite, 7.5 billion people in the world could provide him with survival, which was an astronomical number that would take several years to accumulate.


    The current level of human science and technology is still not high enough, so that things like planet transformation are too far away for human beings, which also leads to the astronomical number of survival points Chen Xin needs to upgrade the planet transformation instrument.


    Of course, this may also have a lot to do with the fact that when Chen Xin completed the planet reformer, the blue star was out of the doomsday state and the mission of the system ended.

 Chapter 539

    A huge transport plane slowly landed on the cleared temporary runway.


    Because the snow in Lucia is thicker than that in Yanguo, the runway is actually just the compacted snow and the marked navigation lights.


    However, the huge transport plane is still very stable at the end of the runway, there is no accident.


    "What are the goods and materials delivered this time?" Standing next to the plane, looking at the cargo unloaded from the cabin, Chen Xin inquired to the staff.


    This is a small upgrade on the performance of the core sent by China. Chen Xin further optimized it to improve the heating efficiency and coverage area. In this way, it can affect more people and provide more survival points for Chen Xin.


    Although the number of survival points that Chen Xin can gain from a refuge is online, no one has said that this energy tower is only for one refuge.


    The situation in the capital of Lucia is different from that in the Republic of Yan. Most of the underground refuge facilities here come from the suvian era. Some of them are dug very deep, even more than a meter underground. For example, the capital subway station is such a deep existence.


    But in addition, the capital of Lucia has many shelters similar to private basements, most of which are products of that era.


    At the beginning, Lucia government did not have as strong executive power and infrastructure capacity as Yanguo, so it only connected a small part of the basement together and built a refuge similar to the community, so it put its main strength on the large refuge established by the government.


    In this case, the scope that can be covered by the establishment of the energy tower should be the scope that the pipeline can be laid, not just the scope that can be affected by the heating place of the energy tower.


    Moreover, the lucians didn''t plan to build this energy tower on the ground, but on the ground. So what the lucians adopted was Chen Xin''s original design of the second energy tower, which closed the heat dissipation of the whole tower body and relied entirely on pipes to transport heat.


    This happens to be in Chen Xin''s favor, because in this way, the pipeline can connect more refuges to avoid the upper limit of the number of survival points that can be obtained by opening a refuge.


    As for Chen Xin, he can upgrade the heating pipeline and energy tower to influence more shelters and survivors, so as to gain more survival.

 Chapter 540

    Chen Xin''s intervention in Lucia''s aid plan is certainly not as simple as upgrading the core of the energy tower.


    After all the supplies were unloaded, the plane rushed back, and the random supplies and engineering teams were received by the base.


    After that, it will be transported directly to the installation site prepared by the lucians, and then the installation will begin.


    The construction of the energy tower is a relatively complicated project. Although the lucians have made a lot of preparations, the installation and connection of the heating pipeline, the shell assembly of the energy tower, and the commissioning of the overall equipment


    There is still a lot of work to do, and lucians are mainly responsible for the peripheral work, The part related to the core technology will be completed by the engineering team of Yanguo.


    "Can''t you teach us technology and let us do it ourselves?" Lucia''s official in charge of the energy tower project complained to Chen Xin. In his opinion, Yanguo has taken so many benefits from Lucia, and a civilian technology should not be so stingy.


    As a matter of fact, we can''t blame Lucia for complaining, because although the aid plan of Yanguo does help Lucia build an energy tower to provide them with heating equipment, the core of the energy tower must be imported from Yanguo. In other words, the relevant accessories and parts must also be imported from Yanguo.


    Even so, if the energy tower breaks down and needs to be repaired, if Lucia wants to repair it, she must have the technical engineer of Yanguo present to repair it.


    Otherwise, it will be regarded as abnormal operation, and Yanguo will not be responsible for the maintenance of any problems later.


    If it was before the disaster, this degree of restriction was very normal. Although it has been very few in recent years, in the 1980s and 1990s, many equipment imported from abroad by Yanguo had such severe restrictions on use.


    The parts must be bought from the designated manufacturer, the price is expensive, and the quality is not even comparable to that of domestic products; Foreign engineers must be present for any disassembly and repair, and even many key core parts are completely welded. If you don''t show them to you, they have to be disassembled and sent back to the original factory, which is expensive.


    It is precisely because of this technological blockade that Yanguo people simply choose not to rely on themselves. From imitation and imitation at the beginning to independent innovation later, they have developed their own technological path from scratch.


    It not only realized the localization of parts, but also realized the localization of a lot of equipment that was heavily dependent on imports.


    And finally out of this road of Yan people, also become very important to their own technology, easily won''t let foreigners learn to go.


    The kind of thing that happened in the 1980s and 1990s, when a few foreigners took a turn in the factory and learned the core technology, will never happen again.


    Although it is the end of the world, the protection of technology still needs to be attached great importance.


    This is not to say that Yan people are stingy. If they are really stingy, they don''t want to help Lucia. It''s just a kind of return to the past.


    So facing the problem of Lucia officials, Chen Xin just shrugged and said: "the core of the energy tower is very precise parts. Even in China, only a few factories can produce such parts that need high-precision processing, and need to use a lot of high-performance materials.


    The core itself is packaged, and it is easy to damage the core if it is disassembled at will.


    It''s because of this that you are not allowed to demolish them randomly. After all, Mao style maintenance or something, no matter how sophisticated it is, can''t stand the toss? "


    "You are prejudiced!" Lucia''s official said angrily, but there was no way to refute anything.


    What''s the point of saying so much when people don''t give you technology? To be able to give you an excuse as an explanation is Chen Xin''s face.


    No matter how much you say, it doesn''t make any sense when this form is better than people.


    Now it''s Lucia who asks for the conditions of Yan state. Even if it''s a little worse, Lucia can only accept them, and there''s no room to talk about them.


    In fact, the current conditions for Lucia are far from harsh, but they are just not willing to accept psychologically.


    Chen Xin saw that the official didn''t say anything more, so he turned around and walked ahead. As he walked, he said to Lucia official who followed him: "after the installation of the energy core, the coverage of the heating field can reach a radius of 500 meters. Under the condition of completely closing the tower and using only pipes, the effective heating range of the heating pipeline can reach 10 kilometers.


    You put the energy tower underground in the city center, which can theoretically provide heating for all shelters within a radius of 10 kilometers, so what''s the layout of the pipeline now? "


    Because this matter involves how much survival Chen Xin can obtain, he is naturally very interested in this matter.Hearing Chen Xin''s question, the Lucia official quickly explained: "at present, all the heat supply pipelines of the official shelters have been connected, and all the small shelters in the area are connecting them to the heat supply pipelines of the official shelters as much as possible, but because of the large number and the troublesome construction, only about 40% of them have been completed.


    We are speeding up the progress, and we expect to reach 85% by the time the tower is completed. As for the rest, there are still some people who are not willing to cooperate? "


    "Who doesn''t want to cooperate?" Hearing that someone didn''t want to cooperate, the expression on Chen Xin''s face suddenly became gloomy, and his steps stopped.


    It''s about the survival he can get. He doesn''t want any problems to affect his survival.


    "Some of the former rioters were originally recruited by the revolutionary army, but now I don''t know why. They are independent from the revolutionary army again. They neither obey the official management nor resist the revolutionary army, and they are very stubborn." Lucia''s officials also had a headache. When they explained to Chen Xin, they could not help complaining.


    Hearing this, Chen Xin frowned and asked, "how many of them are there? How much control? "


    "There are still about tens of thousands of people, mainly concentrated in a few small and medium-sized shelters occupied by them." Lucia''s officials explained to Chen Xin, and at the same time explained to him why they did not clean them up: "the high level did not want to continue the war to destroy the capital, so they tolerated their existence for the time being. We are now working with the revolutionary army to persuade them to cooperate with the reconstruction work, but they are very stubborn and are now in a stalemate."


    "Solve it as soon as possible, if they still don''t want to cooperate before the energy tower is built..." Chen Xin said here. After a pause, he continued: "I will send someone to cooperate with you to demolish it."

 Chapter 541

    Of the first batch of aid to Lucia, the energy tower was the focus, but for lucians, the greenhouse was the most important thing.


    During the construction of the energy tower, the greenhouse has been completed first.


    However, due to the fact that the energy tower for heating and power supply of the greenhouse has not been completed, the greenhouse has not yet been fully operational.


    However, because of the current food shortage in the capital of Lucia, the people of Lucia simply use other heating and power supply facilities first. Although they can''t make the greenhouses run completely, they can also make the seeds go on.


    Although the seeds germinate and grow slowly due to insufficient heating and power supply, these problems can be solved after the construction of the energy tower.


    By that time, the food produced by the greenhouses will be a great solution to the food shortage faced by the capital of Lucia.


    In fact, for Lucia, the food problem is also a classic problem.


    Whether it is kievros founded by Madame dongslai, or the Grand Duchy founded by Ivan IV, Novgorod, which is familiar to the knights, or the Romanov dynasty founded by Peter the great, or even the last suvia and modern Lucia, the food problem has been plagued the country.


    Their latitude is too high, and the cold climate in high latitudes creates a long winter here. More than half of the year, the land is frozen, which undoubtedly brings considerable difficulties to the agricultural cultivation of Lucia.


    After all, half of a year''s land can''t be cultivated. In the primitive farming society, it''s really difficult to increase food production.


    What''s more, in the era of suvia, although they had the largest territory in the world, only one third of it was suitable for farming. Today, the land utilization rate of one third is only 60%.


    In addition to the scarcity of agricultural population, although Lucia used to be a very famous exporter of agricultural products, it was built on the premise that the serfs did not live as well as cattle during the tsarist Russia period.


    In the era of suvia, the underdevelopment and lag of agricultural industry had seriously restricted the economic development of suvia.


    This is also the reason why the corn comrades, the second generation leaders of suvia, would vigorously promote agricultural development. This policy itself has no problems, but unfortunately, the land of Lucia is not suitable for planting corn originated in tropical Central America.


    In Lucia''s time, because of some problems caused by the disintegration of suvia, Lucia''s cultivated land was seriously abandoned. It was only in recent years that Lucia''s current leader took office that this problem was gradually improved.


    But now, the original vast territory is completely frozen by ice and snow, and nothing can be planted at all.


    Therefore, the greenhouse assisted by Yan people is more important to lucians than the energy tower that can supply heat and power.


    Of course, Lucia herself has the corresponding agricultural technology. Greenhouse planting is not the only thing that Yan people can do.


    However, although the lucians master the corresponding agricultural technology, no country in the world is better at farming than the Yan people.


    After all, whether it''s islands, reefs, deserts, snowy mountains or polar regions, even if it''s in space, it''s the people who are farming.


    The lucians have no problem building basic greenhouses, but they can''t compare with the Chinese in terms of crop management and seed cultivation of high-yield crops.


    Moreover, there are still many technical details of planting crops in this environment, which are different from those before the disaster.


    Because Yanguo has a professional team studying the ecological greenhouse and greenhouse planting technology, it has made a lot of achievements in this area, and these are the key points of the greenhouse for the lucians.


    After all, the simple greenhouse technology is not very rare, and it is not too difficult to grow crops. But how to cultivate high-yield crops in today''s environment and limited conditions, and how to improve the yield of crops, are the real core technologies.


    However, unlike the core technology of the energy tower, these technologies were taught to the lucians without reservation.


    It''s not that agricultural technology is unimportant, but that agricultural technology, unlike other technologies, is a technology that allows more people to live.


    People may have no mobile phone, no computer, no Internet, no everything given by modern technology, but people have to eat.


    In fact, Yanguo people''s deep love for land and persistence in agricultural cultivation is due to the fact that we have experienced too many tragedies and disasters caused by insufficient food. This fear even turns it into an instinct, which is engraved in our genes.Therefore, as a miserable people who know that there is no food, Yan people will not embarrass other countries in this matter.


    Other things may be reserved by the Yan people''s Congress considering the influence of various factors, but the Yan people have never considered how to grow more food.


    In fact, there is no need to keep a hand in this kind of thing. After all, agricultural technology itself is a very low threshold thing. It''s just planting crops. Even if there is no technology of Yanguo, the lucians themselves can do it.


    Moreover, in Chen Xin''s view, it is better to provide high-yield crop seeds for the lucians than to keep them technically.


    We should know that the seeds of high-yield crops are specially cultivated, and the genetic characters are not stable. It is normal for the first generation to have high yield, the second generation to have low yield, and the third generation to basically lose high yield.


    If we want to ensure the high yield, we need to use the specially cultivated high-yield crop seeds all the time. Not only that, but also we need to strengthen the planting management and the use of chemical fertilizer.


    Of course, this is not desirable for ecological agriculture, and the research on Ecological greenhouses in the research center is also avoiding this kind of thing.


    Because ecological agriculture is concerned with circular planting. If new high-yield seeds are sown every year, there is no circular planting.


    Of course, the aid to Lucia is just ordinary greenhouses and high-yield crops, not ecological greenhouses used in ecological agriculture.


    It''s not that the country is stingy, but that although the ecological greenhouse has more kinds of food and the overall yield is not low, the construction of the ecological system needs time and more energy, and it can''t produce a lot of food in a short time.


    As far as Lucia is concerned, they need more food in a short period of time, so high-yield crops and ordinary greenhouse cultivation are more suitable for them.

 Chapter 542

    Because Chen Xin has already expressed his attitude, Lucia has naturally accelerated the construction of heating pipelines, and is also stepping up efforts to demolish those still stubborn shelters.


    These refuges are unpopular for both the government and the revolutionary army.


    They not only resisted the official management, but also split from the revolutionary army. Now they are resisting the attitude of both sides at the same time, which naturally makes both sides feel very dissatisfied with them.


    Some of these people belong to the small rich. Before the disaster, they belong to those who have a little money but can''t be called the top class. They also spent money to build their own shelters before the disaster. Although they can''t compare with those oligarchs and the rich, the shelters they built are strong enough and can provide them with enough food supplies.


    These people also rely on the refuges built by these small rich, and led by these small rich, although they are not as capable of mastering an armed force as oligarchs, they also gather a large group of people to close their own area and form a self-sufficient small circle.


    This has undoubtedly brought great trouble to the reconstruction work of the government and the revolutionary army. After all, there are not a small number of these small rich people. They are connected with each other before the disaster. Many people are concentrated in the original rich areas, and the refuges can be connected with each other.


    Because of this reason, when the periphery of their area is closed, the interior is like a small community protected by a fortress.


    In terms of food, these rich people hoard a lot of food. In addition, some farsighted people made greenhouses. In the previous riots, they robbed a lot of things. For a while, they really didn''t worry about the lack of food.


    On the official side, because they didn''t want to destroy the city that was hard to rebuild by force, they didn''t use the army at the first time. They just sent staff to negotiate with the revolutionary army.


    But these people are obviously not ignorant people. Small groups led by the small rich formed an alliance after connecting. They united to resist the official and the revolutionary army.


    However, these people had seen how the government suppressed the oligarch''s armed forces before, so they did not choose to confront each other head-on. They just adopted a non violent and non cooperative attitude. They did not cooperate with the government, but they did not conflict with the government.


    In this way, the government will not easily use the army to solve them, but they can negotiate terms through confrontation with the government, and use the ordinary civilians who are coerced as chips to snatch greater interests for themselves.


    This kind of thing naturally makes the official very dissatisfied, but in order to avoid another war affecting the whole reconstruction plan, the official can only hold his nose and negotiate with these people.


    However, these people just saw this attitude of the official, so they overcharged. At the same time, the lion stuck the upper limit of what the official could pay. A little bit of sawing with the official made Lucia official very uncomfortable.


    Without Chen Xin''s urging, Lucia''s official may be grinding on until a price acceptable to both sides is reached to let this matter know.


    But now Chen Xin says that if the problem can''t be solved before the energy tower is built, he will send someone to help demolish it, and the problem will be much more serious.


    During this period of time, Lucia''s officials had a thorough understanding of who was in charge of all matters in the aid program of Yanguo. They knew that Chen Xinsheng had mastered Titan, power armor, exoskeleton, electromagnetic weapons and many other top technologies, as well as his importance to Yanguo.


    Chen Xin was able to mobilize the Yan army stationed in Lucia at the moment, which Lucia officials did not doubt at all.


    If the army of Yan country is allowed to carry out military operations in its own capital again, it is no doubt for Lucia officials to press their face on the ground and step on it, and even spit after stepping on it.


    In the past, the army of Yanguo could be said to rescue the trapped rescue team. There was more or less an excuse, but now if the army of Yanguo is allowed to carry out military operations in the capital in the name of assisting in demolition


    Even if this is not the world before the disaster, Lucia, regardless of her international image, has to consider the issue of popular support and national cohesion.


    After all, there has been a riot because of the epidemic before. If the people feel that the government has lost its control over the country, and even the demolition of this kind of thing needs the Yanguo army to do for them, it will undoubtedly aggravate the people''s distrust of the government and lead to bigger problems.


    On the contrary, if the government can deal with these problems smoothly, rebuild the capital by relying on the aid project of Yanguo, improve people''s living standards, and properly solve the epidemic problem, then the public support that the government can obtain will undoubtedly be greatly improved.


    In this way, Lucia officials can continue to support in such a bad environment, rather than a riot leading to the destruction of the whole country.


    Lucia''s official leaders are very clear about this. They are not reluctant to leave their own power and status. Although some people are reluctant to give up their own privileges and enjoyment, they know better that if Lucia loses order and leads his official, then disorderly ordinary civilians will only die in this disaster.


    At that time, Lucia, who once had a brilliant history, will fall apart and no longer exist.


    For Lucia''s senior management, they may not be patriots, but it is hard for them to accept that their country and nation no longer exist.


    So this time, Lucia officially united with the revolutionary army and issued an ultimatum to these people who were still struggling.


    They are required to remove all obstacles within the time specified by the government, so that the official construction team can complete the layout of all pipelines. If they continue to resist, the government will forcibly dismantle them, and the possibility of using force is not ruled out.


    The ultimatum was also agreed by the revolutionary army after the official sent people to explain it to the revolutionary army.


    Moreover, the revolutionary army also actively organized the relatives and friends of those who resisted to persuade them, intending to make progress by attacking the heart.


    It has to be said that under the threat of force and persuasion from relatives and friends, a large number of civilians who were coerced were convinced to give up their resistance.


    However, it is not so easy for the leading rich to give up. Although they do not confront the authorities, they are very firm in their attitude of refusing to cooperate.


    One of the radical points is to prevent the civilians being coerced from leaving, intending to completely block their own area and cut off communication with the outside world.


    This has undoubtedly worsened the situation.

 Chapter 543

    "We can''t continue to waste time with these people. They don''t want to have peace talks with the authorities at all. Let''s just tear them down." Outside a still resisting sanctuary, official Lucia officials are negotiating with representatives from the revolutionary army on how to solve the problem.


    At present, there are still several refuges for resistance like this in the capital of Lucia, but a small number of them have been willing to make peace with the authorities after the official ultimatum was issued, and the conditions have been reached, so there is no further resistance.


    But there are also people like this shelter in front of us who not only refuse to compromise, but also show an attitude of sticking to the end.


    This is no doubt very irritating to the official officials, who are not going to bear it any longer and are ready to take violent measures to solve the problem.


    Of course, he does not have the authority to mobilize the army, but Lucia also has the authority to force the police to dismantle. Although the manpower of the police is also very tight now, in order to properly solve this problem, the government has deployed part of the police force to form a special operation team.


    The representative of the revolutionary army naturally knew this. It seemed that he didn''t want things to go to such an extreme step, so he began to persuade and said, "I suggest that we wait and give them another chance to let our people talk to them again! I think their attitude has softened in the last negotiation. There should still be opportunities for negotiation. "


    Of course, the representatives of the revolutionary army did not deliberately oppose the government. Although the positions of the two sides are hostile, they will not hinder each other in the reconstruction of the city.


    It''s just that the leadership of the revolutionary army is just a group of young people with ideals, and most of them are ordinary civilians. As a result, many of them have a relatively simple perspective on problems, and usually use their own personal feelings as the basis for doing things and making decisions.


    Of course, it can''t be said that it''s wrong, but it''s easy to be emotional.


    Just like now, in fact, in the opinion of official officials, he wanted to forcibly demolish it long before the ultimatum was issued, but the representatives of the revolutionary army have been dissuading him, so that things have been delayed.


    However, this time, the official officials obviously did not want to listen to the opinions of the representatives of the revolutionary army. They directly shook their heads and said, "no, we are far behind in progress. The official requirement is that all problems must be solved before 12 o''clock tonight.


    There are only 13 hours left from 12:00 p.m. now. Even if they surrender immediately, we have no time to go in and clean up. There is no time to continue to accompany them! "


    The official''s attitude is very firm, but he is not a bad person. After a hesitation, he said, "I only give you the last half hour. After half an hour, no matter you can''t get out, I will have people demolish you."


    "Thank you! I will persuade them The representative of the revolutionary army expressed his thanks to the officials, and the whole person ran towards the shelter.


    She must seize the time, half an hour is not much time, and she has to persuade the other party to give up resistance, there is no time for her to slowly go in.


    As the representatives of the revolutionary army ran towards the shelter, the officials also began to organize the special action team of the police to prepare for the demolition.


    At this time, someone suddenly came to the official and reported to him, "the Yanguo side sent someone to investigate, saying that they were confirming that there was no heat supply pipeline dredged at present, so as to prepare for the pressure test of the energy tower later."


    "Have the people of Yan come?" The officials had been informed before, which was not surprising. So they said, "please bring them here... Forget it, I''ll go to meet them. You should hurry up and get ready. We''ll take action when the revolutionary army comes back."


    "All right!" His subordinates agreed, and they walked toward the direction of Yan people with the officials.


    However, when they saw the workers sent by Yan state, they were greeting each other, but suddenly there was a gunshot.


    "What''s the matter?" Yanguo''s staff reached out to shake hands and stopped in mid air, showing a puzzled expression to Lucia''s official officials.


    Lucia''s official listened, judged that the gunshot was coming from the direction of the shelter, changed his face and said, "something''s wrong! Take them to the command room! Protect the Yan people


    Then he ran in the direction of the shelter and called the police special action team to take action immediately.


    Yanguo''s staff were surprised by this, but they were still guided by Lucia to their command room, waiting for a result.


    Although Lucia''s police are seriously corrupt, they are still very quick in action, and there is nothing wrong with them. After a short exchange of fire, the police''s special operations team attacked the refuge.


    After more than an hour''s waiting, Lucia''s officials and the Armed Revolutionary Army representatives walked into the command room together.


    "What''s the matter, please?" Yan country''s staff looked at two people have some disheartened appearance, with a bit of curiosity and concern asked.


    "I''m sorry, it''s me!" The representative of the revolutionary army first said sorry, and then explained: "I just intended to take advantage of the last moment to persuade the people inside not to continue to resist. As a result, after I went in, without saying a few words, one of them took out a pistol and said that he wanted to fight with the official. Others wanted to stop him, I was accidentally hit in the arm by a stray bullet while persuading. "


    "So it is. Is it settled now?" Yanguo''s staff picked eyebrows, showed a helpless expression and asked each other.


    The official nodded his head and said, "after we attack, all the resistance has been disintegrated. Now the special action team of the police is carrying out the demolition. They will clear all the obstacles, and then we will let the workers in for construction and complete the layout of the pipeline."


    "That''s good. It seems that you have no problem here." Yanguo''s staff felt relaxed for a while, and a relaxed smile appeared on their faces.


    Because the construction progress of the energy tower is faster than expected, it is necessary to carry out a layout for the heat supply pipeline in order to arrange the trial operation of the equipment. Therefore, Chen Xin specially sent some technical personnel from Yanguo to understand the situation.


    Each of them was divided into an area, and this shelter was the last one to resist in the area the staff member was assigned.

 Chapter 544

    "Academician, Lucia has solved the opponents who are still fighting. At present, all the heating pipelines are being laid according to the original plan and are expected to be completed within a week." A staff member took the statistical report and reported it to Chen Xin.


    Hearing what the staff said, Chen Xin nodded with satisfaction and asked the staff, "what about the construction progress of the energy tower? Where is the construction going? "


    "At present, the main part of the energy tower has been completed, and the relevant supporting facilities are under construction. We expect to complete all the infrastructure construction in three days, and start the pressure test in five days. If there is no accident, formal heating will start in a week." Naturally, the staff are very concerned about the energy tower. When Chen asked, he reported what he knew.


    "Oh? It seems that the construction progress is faster than we expected! " Hearing the report from the staff, Chen Xin couldn''t help exclaiming.


    Originally, the expected construction period was about three to five days longer than the current construction schedule. Now, the construction schedule is so much ahead of schedule, which naturally surprised Chen Xin.


    However, he told the staff: "although the progress ahead of time is a good thing, but the quality must be well controlled, after all the construction is completed, arrange a day for inspection to ensure that all places meet the requirements according to the quality and quantity, and then carry out the pressure test."


    "Yes, academician!" Staff quickly agreed, seriously nodded and said: "please rest assured, we will seriously investigate, will not leave any security risks."


    Chen Xin didn''t say anything more when he heard the staff say that. Chen Xin was very relieved about the meticulous and serious work of these domestic technicians.


    Having said this, another staff member began to report other things: "the second batch of domestic aid is also in preparation. According to the news from China, this batch of aid mainly includes emergency food and medical drugs, as well as high-yield crop seeds for greenhouse use."


    "Is China ready for the second batch of aid so soon?" This surprised Chen Xin.


    He also knows something about the domestic situation. Although he has reached an aid agreement with Lucia, according to Chen Xin''s idea, China should solve its own problems before considering helping other countries. However, he did not expect that the second batch of aid would come so soon.


    The staff nodded and said: "the current situation in China has improved. Because the earthquake has passed, Southwest China is now in the process of post disaster reconstruction. Due to the adoption of new technologies, a lot of manpower and material resources have been saved. In addition, the greenhouses in the Qinghai Tibet region are in the harvest period, and there is still plenty of food, so the second batch of aid materials can be organized so quickly."


    Before the disaster, the state built a large number of greenhouses in the Qinghai Tibet region and Lingnan region to deal with the food problem after the disaster.


    Because it''s not ecological greenhouses, these greenhouses produce grain periodically. Now it''s harvest time, so the country has the spare power to support Lucia.


    After understanding the situation, Chen Xin nodded and arranged for the staff to receive this batch of materials: "can the warehouse of the base hold this batch of materials? First, store these materials in the base. When Lucia''s situation is more stable, we''ll give them the materials. "


    Food and medicine are different from previous energy towers and greenhouses. For Lucia today, only Lucia officials have the ability to build and manage energy towers and greenhouses, and the revolutionary army still lacks the ability to do so.


    But in the case of food and medicine, they are urgently needed for both sides, and they can be used as long as they have them.


    In order to avoid the situation that the two sides scramble for materials, Chen Xin thinks that he should temporarily store these materials in the base, wait for the situation between Lucia''s official and the revolutionary army to stabilize, and then give them these materials.


    The staff members have no objection to Chen Xin''s decision. After understanding the current situation in Lucia, they also feel that they can''t directly hand over these materials to Lucia.


    After all, the amount of materials is limited. It''s not enough to give them to Lucia or the revolutionary army, let alone divide them into two parts and give them to both families.


    Moreover, they are not sure whether the goods can be delivered directly to the people in need under the current situation.


    Out of this worry, a staff member suggested: "since this batch of materials is not suitable for either Lucia official or the revolutionary army, how about we distribute them ourselves?"


    "Isn''t that right? If we do that, both of them may have different opinions? " Another staff member felt that this was not a reliable approach.


    "But now this batch of materials is badly needed by the people. It''s not appropriate for us to hold them in our hands like this." The staff who proposed to distribute the materials themselves pointed out a key point. In his opinion, since the materials are aid materials, they should be distributed to the people in need immediately.


    As for this problem, Chen Xin stopped them from saying: "it''s very easy to cause unnecessary misunderstandings because our distribution is inappropriate. At this time, people in Lucia are very nervous. If we cause any unnecessary misunderstandings in the process of distributing materials, we will only delay more things.


    So we''d better wait until the construction of the energy tower is completed and the situation in the capital of Lucia is improved, and then hand over these materials to Lucia. Now you''d better send someone to inform Lucia''s official and the revolutionary army that they have these materials, and explain the situation. We must make it clear that we don''t want to detain these materials, but we don''t want to cause trouble. "


    "Well, academician, I''ll contact Lucia''s official and revolutionary army representatives later." When the staff saw that Chen Xin had made a decision, they didn''t go on. They just nodded and agreed.


    "Is there anything else besides these two things?" Chen Xin looked at the staff in front of him and asked them.


    "Lucia is preparing to move people from other areas to the heating area of the tower after the construction of the tower, and rebuild some damaged areas. I hope we can help." Another staff member said, and spread the drawings he brought in front of Chen Xin: "this is their design plan, as well as the new shelter construction drawings. Please have a look at them."


    Hearing what the staff said, Chen Xin picked up the drawing and looked at it carefully.

 Chapter 545

    As for the shelter Lucia wants to rebuild, Chen Xin is naturally full of interest and a desire to get involved.


    After all, for him, as long as he takes a hand in the process of reconstructing the refuges, he will naturally be able to obtain the survival provided by these refuges. Chen Xin is very willing to do this kind of beneficial and inexpensive thing.


    It is for this reason that Chen Xin, after seeing the reconstruction plan and design drawings of the refuge sent by lucians, asked the staff to contact Lucia and said that they could provide some technical support.


    As a matter of fact, Chen Xin can really provide a lot of help and ideas for the reconstruction plan of lucians'' shelters.


    Most of the refuges that lucians want to rebuild are places damaged in the previous conflict, which were originally private refuges built by oligarchs to live in.


    The internal space is vast, and the supporting facilities are perfect, also has a very good defense.


    Otherwise, the oligarchs and the armed forces they controlled could not have resisted Lucia''s official Army for so long.


    Just because the defense is good, when the official army attacked, it was inevitable to use relatively strong firepower to make a mess here and had to carry out reconstruction.


    However, the overall framework of the refuges built by the oligarchs before is still good. By taking this as the core, expanding outward, connecting other refuges around or opening up new space, we can build a medium-sized refuges that can accommodate thousands of people, similar to small communities.


    In fact, it was also inspired by those who resisted the government. They gathered together to form a group similar to a small community. Naturally, this model can also be applied to the design of shelters.


    Of course, Chen Xin was very interested in this, and even went to a shelter planned by the lucians for on-the-spot investigation.


    Lucia''s official people are very surprised. On the one hand, they are very happy that Chen Xin can help them with their reconstruction plan. On the other hand, they are very worried about his safety.


    Chen Xin is the leader of all the people in Lucia, and he is also an important scientist in the country. If anything happens to him, not to mention the possible military conflict between the two countries, even if the country only cuts off aid, Lucia can''t afford it.


    Therefore, Lucia''s official deployment of a whole special force in the area where Chen Xin wants to visit on the spot is to prevent dangerous elements from threatening Chen Xin.


    Chen Xin doesn''t think it''s an exaggeration. That is to say, in Lucia, if he is at home, his treatment will not be much worse or even more excessive.


    Therefore, in order to reduce unnecessary troubles, Chen Xin took several soldiers equipped with heavy machine armor as escorts, and he also put on nano armor and adjusted it to the defense mode, so as not to be unable to react when something really happened.


    And under such layers of protection, Chen Xin also came to this shelter in the planning and reconstruction.


    The previous fierce fighting made the walls full of bullet holes. In some places, it was like shelling, and the whole collapsed into a pile of scorched ruins. It was obvious that there had been a fire before.


    For such a shelter built underground, fire is very dangerous. Maybe the whole shelter will burn up and everyone will die together.


    After all, it''s underground. The air is not circulating and the environment is closed. If there is a fire, it will be suffocated even if it is not burned.


    Therefore, both Yanguo and Lucia pay great attention to the safety of fire and electricity in underground shelters.


    Stepping on broken bricks and stones and walking through a corridor beyond recognition, Chen Xin finally came to a place that looked clean and tidy.


    It can be seen that this place should have been specially cleaned up, at least the broken bricks and cement dregs have been cleaned up, and the degree of damage here is relatively small, which is much more complete than the previous corridor.


    "This is the hall of a former oligarch''s refuge, which was used as a stronghold by his armed forces. Therefore, the resistance in the corridor in front of him is very fierce, and the army took some effort to attack." Lucia''s official stood beside Chen Xin and introduced him nervously.


    But Lucia''s officials were not nervous. Beside him, there were four steel giants more than two meters high staring at him, and these steel giants still held weapons that could instantly beat him into a pile of meat sauce.


    Even if we know that these steel giants are just Chen Xin''s bodyguards and won''t do anything to him, it still makes him nervous.


    Chen Xin shook his head and didn''t say much about it. Maybe it''s better to make people feel scared than to make people feel kind. However, he didn''t have the heart to think about these things. Instead, he asked the official, "how are you going to transform this place and what are you going to use as energy?"


    This is also a topic that Chen Xin is more concerned about. In the planning drawings and shelter design drawings sent by lucians, there are circuits and power supply facilities, but they do not carefully indicate what kind of functions they are.


    Hearing Chen Xin''s question, Lucia''s official quickly explained, "we plan to adopt the nuclear battery technology left over from the suvian era."


    "Nuclear battery? Those things for the nuclear lighthouse? That''s quite appropriate. " On hearing this, Chen Xin understood what Lucia''s officials said: "those lighthouses can still operate smoothly for 30 years after the disintegration of suvia. Even if they have been in service for more than 10 years, they only have problems because of aging and lack of maintenance, which is enough to prove that their technology and quality are reliable.


    But can you produce this kind of nuclear battery now? Do they have enough output power for a shelter? That''s just to power the lighthouse, right? Is there enough electricity? "


    In Chen Xin''s impression, the power of that thing is not high, which is less than 100 watts.


    However, Lucia''s officials showed a trace of pride on their faces and said to Chen Xin: "after the disintegration of suvia, we have not done nothing. We have made some breakthroughs in this technology, and the performance of nuclear cells has been greatly improved. If a refuge of this scale uses multiple batteries in series, We can still guarantee the power supply. "


    Hearing what Lucia officials said, Chen Xin''s face became a little strange.


    As a matter of fact, the nuclear battery that lucians refer to is the isotope thermoelectric battery that he made in China. However, the nuclear battery used by lucians is still at the level of normal science and technology, far from Chen Xin''s black science and technology nuclear battery.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 546

    "Nuclear battery technology?" Chen Xin thought about it, but he still didn''t mention the isotope battery technology currently being used in China with lucians. It''s more appropriate to let the national level negotiate this kind of thing.


    Although both nuclear cell technology and isotope cell technology are nuclear cell technology, and they are similar in principle, the gap between them is unreasonable. Chen Xin is not sure whether the state will agree to share isotope cell technology with Lucia.


    This is not ordinary technology. Unlike the energy tower, it is enough to affect the strategic balance between the two countries.


    Although Lucia may not turn over with Yanguo after getting isotope battery technology, even if he turns over, he may not win, but Chen Xin doesn''t want to gamble on this kind of thing.


    Although he wants to get more survival, there are some things he doesn''t need to do.


    "Now that you can solve the energy problem, let''s not get involved." Chen Xin said to Lucia''s official, but as if he thought of something, he asked him, "I''ve seen your shelter design, and I think some places can optimize the design. I don''t know who your designer is. Can I have a chat?"


    "Ah! This... "Lucia''s official was very strange. His face became very strange. It seemed that he was in a dilemma, but he didn''t know how to explain it to Chen Xin.


    Seeing him like this, Chen Xin picked his eyebrows. He was slightly unhappy, but he still said, "is there any inconvenience? If so, forget it, but I''m sorry I can''t share my experience with the designer about the shelter design. "


    "I''m sorry, it''s not that we don''t let you communicate with him, but..." Lucia''s official obviously noticed Chen Xin''s emotion and quickly explained to him: "in fact, the planning drawings and design drawings we provided are a strategic plan from the period of suvia.


    At that time, because of the cold war, the high level of the Soviet Union developed a shelter plan to resist nuclear weapons attacks. These air defense shelters under the capital, as well as the planning and design drawings we provided, were part of that plan.


    However, at that time, suvia only completed the construction of the underground air defense shelter. Because the thermonuclear war did not break out, suvia did not promote the plan at that time, but only completed the relevant preparatory work.


    With the disintegration of suvia, this plan has been handed down to the official hands of Lucia. Because of the current situation, we turned over this old plan and made some adjustments on this basis, and then implemented it as a reconstruction plan. "


    "The plan of the suvia era?" Hearing this, Chen Xin was not surprised at all. Instead, he took it for granted: "I didn''t expect that 30 years after the disintegration of suvia, you are still enjoying its legacy."


    This obviously embarrassed Lucia''s officials, but in fact, he could only be silent.


    However, Chen Xin obviously didn''t want to embarrass him by saying this, so skipping this topic, Chen Xin asked, "who is the designer in charge of this project now? I think your drawings can be adjusted. We can share with you some of the technologies used in shelters. I believe you should use them. "


    Although Chen Xin will not provide isotope battery technology to lucians, some other civilian technologies can be shared with them. In this regard, he has asked for instructions from China and obtained permission from relevant authorities.


    "Is Yanguo willing to share the technology in shelter construction? That''s great Lucia''s officials were overjoyed, and the willingness of Yanguo to provide technical assistance was a great help to them.


    Although Lucia''s technical strength is not poor relying on the legacy of suvia, her development in recent decades has been very difficult, and her engineering construction capacity is totally unmatched with that of Yanguo.


    As the world''s largest infrastructure country, Yan''s engineering construction capacity is universally recognized. They are willing to share technology, which is a great surprise to Lucia and her husband.


    Even if they only share civilian technology, what Lucia needs now is these basic technologies that can speed up the construction of shelters.


    Thinking of this, Lucia''s officials quickly told Chen Xin, "I''ll report to them immediately and let them make arrangements."


    Chen Xin nodded and motioned to Lucia''s officials to report. At the same time, he walked deeper into the shelter.


    Through the corridor and down to the lower level, Chen Xin saw the luxurious decoration and living conditions left by the oligarchs when they built the place.


    "I don''t know what to say." Chen Xin could not help shaking his head slightly.


    Although it is said that the gap between the rich and the poor has been inevitable since human beings left the primitive society and had private ownership, it is still a matter of regret that some people can still live a luxurious life, while others are not well-dressed and precarious.


    Although for Chen Xin, his refuge is also enough luxury and enjoyment, it is far from those built by oligarchs.


    He is the refuge of upgrading the system bit by bit, while these oligarchs build these seemingly luxurious shelters directly with money.


    Of course, Chen Xin doesn''t mean that they can''t enjoy luxury, nor is he a man who hates the rich. He just thinks that if we can use the money for luxury to help more people, we may have a good life.


    Just like the famous story, a small group of people lived in the golden palace, ruling the people in the thatched houses and the people without houses. In the end, a group of people stood up, overthrew the rulers in the golden palace, demolished the golden palace, and then built more stone houses to let more people have houses.


    Chen Xin doesn''t want to be the one who demolishes the golden palace, but he thinks that people in the golden palace can at least let people who have no house have a thatched cottage.


    Of course, this is not what Chen Xin needs to care about or do. If people who have no houses and live in thatched houses feel that they can''t make it, they will go back and overturn the golden palace themselves.


    As for whether they demolished the golden palace and built the Silver Palace, or lived in the golden palace, that was their own business.


    As far as Chen Xin is concerned, he is only concerned about whether it can provide him with survival after the transformation.


    Because only in this way can he make the frozen world melt, from cold winter to spring.

 Chapter 547

    As for Chen Xin''s willingness to provide technical assistance to help them rebuild the refuge, lucians were naturally very happy. They soon arranged a meeting between Chen Xin and the person in charge and designer of the refuge reconstruction plan.


    "Isn''t your shelter designed to grow greenhouses?" In a conference room, Chen Xin knocked on the design drawings of lucians and asked them this question that puzzled him.


    "Because of the energy problem, we can only guarantee the power supply and heating of these shelters. If we want to build another greenhouse, the power consumption will at least double, which we can''t afford." The person in charge is very helpless hands a spread, said they do not make the reason of planting greenhouse.


    After hearing the person in charge say this, Chen Xin was stunned to realize that lucians are not from the state of Yan. With the energy tower and isotope battery technology provided by Chen Xin, the energy problem in this eschatological environment has been solved, and large-scale greenhouses can be built.


    But after thinking about it, he asked them, "how did those people solve the food problem in these shelters before? It''s not just about reserves, is it? "


    "Well, this..." the person in charge and the designer looked at each other, and the designer said: "they have a greenhouse, but it''s only a small greenhouse. They can afford the food consumption of about a dozen people, and the energy consumption is not high. They can afford this kind of consumption, and even raise some fish.


    However, the shelter after our transformation will accommodate nearly 5000 people, and their original greenhouse is only enough to provide an extra meal for the managers. So we just canceled the greenhouses, and the food supply of these refuges depends on external input. "


    The designer explained the reason, but he didn''t say that the government controls the food supply channel. Even if someone wants to make trouble, as long as the government cuts off the supply channel, it can directly solve the problem.


    It''s just that this kind of thing can be done, but it can''t be said. Otherwise, the public will know that the official purpose is like this, which will only cause more trouble.


    Chen Xin thought about the reason why he couldn''t say it, but he pretended not to know: "this can''t be done. What if there is something wrong with your food supply? Watching these people starve to death? It''s better to have a greenhouse in the shelter where they can produce food. "


    "This..." the person in charge hesitated for a moment, thought about it and asked Chen Xin, "how to solve the energy problem?"


    "Ground source heat pump." Chen Xin has long had a plan for this. What''s more, his own shelters are still using this system, so he explained: "by laying pipelines in the shallow strata, we can use the shallow geothermal to obtain energy.


    Although this technology can''t get a lot of energy, it''s OK to maintain at least one greenhouse, so that even if 5000 people can''t be self-sufficient, they can keep on for a long time in case of emergency. "


    After hearing Chen Xin say so, the person in charge and the designer had a quick discussion in a low voice. Then the person in charge asked Chen Xin, "we don''t have the budget to apply this technology, and we don''t have the relevant equipment. Can Yanguo help us solve this problem?"


    Lucia''s project leader is obviously calculating what he wants here. If Yanguo does not provide assistance, it can naturally follow their original plan without changing anything.


    But if Chen Xin says that Yanguo can provide equipment assistance, it is not impossible to increase input. Just control the scale of the greenhouse and make its output unable to meet the food needs of the shelter population.


    Of course, he can also give the yanguobao a budget according to the design that can meet the needs of the refuge population. As for the follow-up construction, he can deduct part of the equipment and budget and use it in other places, such as building a new shelter with perfect facilities for the official.


    Chen Xin did not know that Lucia''s project leader would have such an idea, but he did not directly agree.


    Although China has given Chen Xin certain permission to provide technical assistance to the lucians, Chen Xin is not stupid enough to say that Yanguo can provide assistance.


    He just thought about it for a moment and said, "we can provide you with the relevant technology, provided you have this need. As for direct material assistance, it''s not up to me to decide. If you really need it, you can ask for it at home. You need to talk about how you will help yourself. "


    At this point, Chen Xin also pretended to shrug his shoulders humorously: "this technology has been very mature in Yanguo, and we have also had large-scale applications. A set of equipment can even heat and power a shelter with more than 5000 people. With your nuclear batteries, it is enough to ensure that this shelter can be self-sufficient."


    While saying this, Chen Xin turned over the design drawing on the table again and said to two lucians, "there are some problems in your architectural planning. Private kitchens can really improve people''s happiness, but for the refuge as a whole, they are hidden dangers.


    Even if the use of induction cooker is also difficult to ensure the absolute safety of electricity, in case of fire and other things, it will endanger the whole refuge.


    So I suggest that you adopt a centralized food supply mode, such as the dining hall in the era of suvia. I think this drawing should have been designed in the same way, right? In this meeting place that you added, it should be the canteen in the original drawing design. "


    "Yes, we consider the privacy, personal taste and habits of the people, so the plan is to design a simple kitchen for every family. At least they can make something they want to eat. The canteen doesn''t feel good." The designer quickly explained that the reasons given seemed to be very sufficient, with typical correct ideas, respect for privacy and freedom.


    However, Chen Xin mercilessly tore up this boring lie, pointed to the drawing and said: "don''t joke, your original plan is to provide food from the outside. Unless you can ensure the diversity of food, the most appropriate way is to provide everyone with standard meals!


    Under such circumstances, don''t tell me what kind of food you think people can still make on it! In our country, there is an old saying that "a skillful woman can''t make a meal without rice." you can''t even guarantee food supply, and people can''t have enough to eat. How can you spare yourself to study food practices? "


    "This..." the designer face some embarrassment, but turned his eyes to the side of the person in charge, cast to him for help.


    The person in charge was blushed by the designer, but he still tried to explain to Chen Xin: "Mr. Chen, please listen to me..."

 Chapter 548

    Although lucians found various reasons, they did not succeed in persuading Chen Xin. Instead, they agreed to Chen Xin''s amendment plan under the threat of not providing technical support.


    Lucia''s new shelter will adopt Chen Xin''s revised design, add an additional planting greenhouse maintained by ground source heat pump, and replace the separate kitchen of each household with a collective canteen.


    In addition, the construction technology provided by Yanguo will also be used to optimize the building structure. The original independent basement buildings and the core area, which were originally only connected in series, will be transformed into the form of household rooms as the main living space, with the central functional area.


    This naturally increases the cost and investment of the whole reconstruction plan, and also goes against the original idea of Lucia.


    However, with the support of construction technology provided by Yanguo, the construction cost itself has not increased too much. On the whole, it is only about 15% more than the original reconstruction plan of lucians.


    In exchange for the 15% increase in cost, the number of people that can be accommodated in the shelter has increased by 20%, from 5000 originally designed by lucians to 6000, and the living and living conditions have been greatly improved.


    In the face of such a situation, even if the person in charge of Lucia is reluctant, he can only choose Chen Xin''s plan.


    After all, if we use their original plan, both the construction investment and the construction time are far greater than the current plan, but the effect is not as good as Chen Xin''s plan.


    With Chen Xin''s design, they can completely take down the population that originally needed five shelters to accommodate with four shelters. In this way, the construction cost of one shelter can be saved.


    It is clear to the lucians that which of the four refuges with a 15% increase in construction cost or the five refuges with the original construction cost is more expensive.


    It is for this reason that Lucia will officially agree with Chen Xin''s design.


    On the other hand, after Chen Xin sent the result back to China, China was also very satisfied with the result.


    After all, although the Congress provides technical assistance to Lucia, these things are not free.


    Although some of them were provided to Lucia in the name of donation, it is well known that free is the most expensive.


    All these things provided by Yanguo are paid by Lucia now or in the future.


    As for what to use to repay, Lucia, who needs to repay now, can use the technology or material objects of the suvian period to pay off the debt, while what needs to be repaid in the future is probably minerals and other things.


    In the current situation, land is not of great significance. Otherwise, Chen Xin wants Lucia to return the 1.5 million square kilometers of land occupied by Tsarist Russia, and let uriyasutai return to Yanguo, especially the tangnuwulianghai area, which is the territory of Yanguo directly seized by suvia!


    In fact, Yanguo''s high-level officials don''t have such an idea either. It''s just that there are basically no people in these areas now, and they have become no man''s land. Moreover, the living environment is very bad. To recover these areas, it needs a lot of investment in infrastructure. Not to mention, it also needs a lot of people to stay for a long time, and it is difficult to provide any production.


    In addition to the nominal harvest of recovering lost land, these areas can not provide any practical benefits for the country, but consume a lot of resources.


    It is for this reason that although the senior officials of Yanguo think it''s a pity, they still choose something more practical after careful consideration.


    Chen Xin did not express any opinions on this, but did his job well.


    Although for Chen Xin, if the country is willing to recover these areas, he has a way to turn them into productive and beneficial places for the country, on the whole, it still needs a lot of investment.


    Taking the current situation of Yanguo as an example, even if Chen Xin can use the system upgrade to turn the situation into the most favorable situation, Yanguo, who has just experienced the southwest earthquake, really can not afford such a huge investment to recover the lost land.


    However, Chen Xin wrote a feasible plan and handed it in to the senior management for reference.


    What this plan needs to make use of is Chen Xin''s mobile base. Relying on the self-supporting ability of the mobile base, the mobile base will be stationed in these areas, and then a semi permanent modular base will be built and developed on this basis.


    In these areas, although there may be no other production, there are still some mineral resources, which can provide a lot of industrial raw materials for domestic construction.


    It''s just that this plan still needs a lot of investment, and Chen Xin is not sure whether the senior management will do it or not, so he just submitted the plan and did not continue to ask.


    His main job now is still on the weather controller.


    After two upgrades, the weather controller has been repaired and ready to use.


    Chen Xin is now planning when to start the machine and conduct an experiment.


    But it''s not so easy to accomplish. After all, this machine was originally designed by the suvians to be used with special chemicals.


    Now Chen Xin has only replaced its parts and optimized its structure, but has not optimized and upgraded its working efficiency and operating principle. Therefore, if Chen Xin wants to start the machine for experiment, in theory, he still needs to spread chemicals to see the effect.


    Of course, if you just start the machine to see if it can be used, or what effect can be achieved after the machine is turned on, you don''t need to be so troublesome. Just start the machine.


    During this period, the isotope generator transported from China has been assembled and connected to the base circuit to generate electricity. The problem of power required for the operation of the weather controller has been solved. Now the start-up test conditions of the weather controller are basically ready.


    So Chen Xin is now planning a start-up test of the weather controller.


    Although the results of the experiment itself may not have any effect, after all, according to the design of the suvians, special chemicals are needed to work, Chen Xin decided to start the machine to have a look.


    After all, only when the machine is started can we collect relevant experimental data and understand what the machine can do.


    After collecting these data, Chen Xin wants to continue upgrading the machine and knows where to start.

 Chapter 549

    Since Chen Xin has decided to start the experiment, he will not delay.


    With the highest authority of the whole base and the full support of the state, he didn''t need to discuss this kind of thing with others, so with Chen Xin''s order, the whole base began to run, and began to make preparations for the operation test of the weather controller.


    It''s said that we need to prepare, but actually there are not many things to prepare.


    The whole equipment has been upgraded by Chen Xinxin. The old parts and inefficient structure have been replaced. After upgrading, the whole machine is the same as the new one.


    And the places that might have security risks were also checked out, and they were adjusted when Chen Xin upgraded last time.


    At present, the whole weather controller can be said to be in the best state. When the suvians first built it, it was not as good as it is now.


    Therefore, the preparation before the experiment is just to clear the area that may be affected, let the personnel of the base operate according to the safety regulations, and prepare for the unexpected situation that may be caused by the experiment.


    It has been said before that the principle of weather controller is to transmit specific microwave to affect the temperature in the area, thus affecting the weather.


    The chemical used by the suvians when they designed it is also a kind of special agent that can quickly change the temperature in this band of microwave, so the whole weather controller is actually a huge microwave transmitter.


    Now, after more than 30 years of dust, this huge machine is finally running again.


    Standing in the suvia style central control room, Chen Xin looked through the thick glass of the observation window at the huge coil buzzing in front of him due to charging, and asked the staff who were working in front of the operating platform: "what''s the situation now?"


    "It is reported that the power supply is normal, the output of isotope generator is stable, all lines are free of faults, and the system is charged with 85%. It is estimated that the charging can be completed in three minutes." The staff took a look at the display of the instrument on the console and reported to Chen Xin.


    Chen Xin nodded, looked at another staff member and asked him, "has the personnel in the relevant area of the base been cleared?"


    Because it is not sure whether the microwave emitted by the weather controller will cause harm to human body at present, it is necessary to confirm that the personnel in the relevant area have been cleared before the experiment, otherwise, if someone is exposed to excessive microwave radiation, it is likely to suffer huge harm.


    After all, not everyone is a green man. After being exposed to excessive gamma rays, he can still mutate into a super fierce man.


    "All security areas in the base have been cleared, and all personnel stay in a safe place." The staff nodded at Chen Xin, indicating that there was no problem.


    Hearing this, Chen Xin nodded slightly, looked at the watch on his wrist, raised his voice and said to everyone, "everyone, prepare for the last three minutes countdown, prepare for the first start test of weather controller!"


    With Chen Xin''s voice, everyone became more nervous and redoubled their work to avoid any accidents and mistakes.


    "Academician, drink water!" A staff member handed over a cup to Chen Xin. The cup was steaming, and several pieces of tea that had not yet been fully soaked were rising and falling.


    "Tea? From home? " Chen Xin took the cup, showing a look of surprise: "this is a good thing! Not much now? "


    While expressing surprise, Chen Xin also took a sip from his glass.


    Although he didn''t like tea very much, after such a long time, drinking hot tea again made Chen Xin feel nostalgic.


    "Well, I brought this with me when I came here. I have a friend who is responsible for agriculture. They still have some tea trees left, so they can get some tea." The staff member nodded to Chen Xin and explained softly.


    Hearing this, Chen Xin couldn''t help picking his eyebrows: "did you keep the tea tree? It''s not easy! But then, when we can restore the environment, the traditional culture of tea will not die out. "


    After the impact of meteorites, more than 99% of the world''s species have been extinct, and most of the animals and plants have disappeared. Any species that can be preserved is very precious.


    Not to mention tea for Yan people, it is an ancient existence that runs through thousands of years of Yan history.


    "Yes, but I don''t know when I can get the environment back." The staff also felt that they were very concerned about when they would be able to restore the environment to what it looked like before the disaster.


    In this regard, Chen Xin just chuckled and said to the staff member, "there will be such a day."


    With that, he looked back at the huge coil outside the central control room.


    At this time, the staff in front of the console also reported: "the machine is fully charged, all systems are running normally, and the test can be started!"


    "Countdown ten seconds, ready to start!" Hearing this, Chen Xin announced the start of the experiment without hesitation.


    The central control room seemed to be quiet all of a sudden. Only the staff in front of the console were counting down: "ten, nine, eight, seven..."


    And with the countdown of the staff, a red button on the console has been lit up, and the staff''s fingers are on the button.


    Everyone is watching the finger nervously. As soon as the finger is pressed, the weather controller will be activated.


    "Five, four, three..." with the countdown, someone could not help muttering "God bless", obviously expecting the success of the experiment.


    Chen Xin can''t help but feel a little nervous. Although he knows that this experiment is just to start the machine and there won''t be any problem, he is also nervous when the truth comes.


    "Two! One! Start The last two counts down, the staff pressed the flashing red button.


    There was an indescribable buzz and the weather controller was activated.


    Chen Xin came to the observation window several steps ago. In front of his eyes, the huge coil was converting the filled electric energy into microwave. The high-frequency sound produced by the machine was beyond the range of human ears, but it caused a brief tinnitus in everyone''s ears.


    But these are not the focus of Chen Xin''s attention. He just stares at the coil in front of him.


    Until one minute later, the staff reported to him: "academician, the weather controller runs for one minute, all the systems are running normally, the machine has no fault, the test is successful, will you stop now?"


    "Well, it can be shut down." Chen Xin nodded, which made the staff stop the machine.


    After the machine stopped, the hum in Chen Xin''s ear disappeared, and then came warm applause.

 Chapter 550

    The success of the experiment is, of course, very encouraging and gratifying.


    But the staff at the base didn''t have time to celebrate, they were gathering the test data.


    The cost of such an experiment is amazing even before the disaster. It not only needs to consume amazing power, but also the consumption of equipment operation and subsequent maintenance is a huge consumption.


    After all, the volume of the weather controller is here, which is a very large equipment to be installed in a whole base.


    So every test is very valuable, and the results of the test, as well as the test data that can be obtained in this process, become more and more precious.


    That''s why everyone seems more busy after the success of the experiment.


    Fortunately, we have prepared in advance, so the collection of test data is very fast.


    "Academician, this is the detailed data of this experiment." The staff presented the collected test data to Chen Xin, and said: "in this test, the total startup time was three minutes, and the target area was continuously irradiated. Because the irradiation range was reduced to the minimum range, the microwave irradiation was relatively concentrated, and the test results were obvious.


    According to our observed data, although the irradiation time lasted only three minutes, the temperature of the target area increased by about 12 ¡æ, from - 109 ¡æ to - 97 ¡æ, and the effect was very obvious. With the short rise of temperature, there was also a large airflow disturbance, and the instantaneous wind in the target area reached level 7.


    In addition, there are other relevant changes, which have been recorded in detail and attached to the report. Academician, you can check them at any time. "


    Chen Xin nodded and opened the report recording the test data. However, he frowned and asked the staff, "is there no problem in recording the temperature? It takes three minutes to raise the temperature to 12 ¡æ. Even if we reduce the radiation range to the minimum, the effect is not so good, right?


    According to the experimental records of the suvians in those years, when they first started up, it took them 15 minutes to continuously irradiate, and then the temperature of the target area increased by 3 ¡æ, and the gap was too big. "


    It''s no wonder that Chen Xin was surprised. According to the experimental data handed over to them by the lucians, when suvia built the weather controller, a start-up test was carried out. Just like Chen Xin, they started the machine to irradiate the target area without spreading chemicals.


    According to the test records, the irradiation lasted for 15 minutes at that time, which made the ambient temperature rise from 21 ¡æ to 24 ¡æ. After the temperature rise, the wind force above level 5 appeared in the target area, and there was no other obvious effect.


    But this time, Chen Xin and his team started the experiment, which lasted only three minutes, and the ambient temperature rose to 12 ¡æ, which is really incredible.


    Even if Chen Xin upgraded the equipment twice and improved the efficiency of the machine, there would not be a gap of more than ten times, right?


    If the temperature is raised to 12 ¡æ in three minutes and the irradiation lasts for half an hour, can the temperature of the irradiated area rise back to zero?


    While Chen Xin was thinking about this, the staff explained to him: "this may be related to the low ambient temperature when we tested."


    "Oh? Why do you say that? " Chen Xin heard the staff say so, and immediately looked at him curiously.


    "The operation principle of this weather controller is to affect molecular motion through microwave, increase molecular potential energy, and cause polar molecules in the air to vibrate, so as to generate heat and improve the ambient temperature." According to the working principle of the weather controller, the staff told Chen Xin their judgment: "when the ambient temperature is above zero, the molecular motion in the air is relatively active, so when the suvians carried out the experiment, there was no obvious change.


    When we carried out the experiment, the ambient temperature was more than 100 degrees below zero. In this environment, the movement of molecules was very inactive. Suddenly, they were affected by microwave and moved violently, generating a lot of heat. It is also possible to cause the temperature to rise rapidly. "


    "It''s possible." Listening to the explanation of the staff, Chen Xin did not deny this conjecture.


    The change of temperature is the process of energy transfer between two objects, and the efficiency of energy transfer is affected by the process,


    Therefore, if the conditions are different, the efficiency of energy transfer is also different.


    For the simplest example, putting ice into boiling water is obviously different from putting ice into normal temperature water.


    So it is possible that the current result is affected by different ambient temperatures, and the staff''s guess is also possible.


    But at present, the data obtained from the experiment is not enough. Only this time, it is impossible to confirm or falsify this conjecture.


    After thinking about it, Chen Xin said to the staff, "your guess is not impossible, but there is a lack of empirical evidence, and I can''t judge whether it is so. We need more experimental data for comparison.


    In addition, you can also send the data to China and ask other people''s opinions.


    In addition, we also need to consider the use of weather controller. If the temperature rises too fast just because of the influence of low temperature, we need not worry too much.


    But if even the ambient temperature is above zero, we can reach such a temperature rise, then we need to pay attention to avoid causing any problems both in the test and in the actual use later. "


    Chen Xin has to worry that if his guess turns out to be true, the weather controller can really quickly heat the temperature of the target area in a short time, and it is little affected by the ambient temperature


    No, even if it is greatly affected by the ambient temperature, as long as it can quickly heat the temperature of the target area, the weather controller is a powerful terrorist under the current ambient temperature of tens of degrees below zero for the whole blue star.


    As long as it is aimed at a certain area, and then quickly heating the temperature of the area, even if there is no melting ice and snow, just heating the air can kill people.


    What''s more, killing people is invisible, which is similar to the kind of weapons of mass destruction that Chen Xin once saw.


    Thinking of this, Chen Xinli could not help but feel a little worried. He motioned to the staff to get busy first. At the same time, he was considering whether to tell the country about it.


    Although this weather controller is developed for the purpose of meteorological weapons, meteorological weapons are only indirect killing. If his worries come true, it can be a powerful direct killing weapon. Chen Xin needs to consider eliminating the possibility of this kind of thing and limiting it to a controllable range.

 Chapter 551

    Whether the weather controller will become a weapon or not, after Chen Xin seriously considered it, he found that it was still up to him.


    The principle of microwave heating is not complicated, and it is not that no one has ever thought of applying them to the military, and microwave weapons have been conceived for a long time.


    It''s just that there are too many technical problems that can''t be solved. It''s the same as the smooth edge tank made by the people of suvia in those years. Although it''s not impossible to make it, it''s very impractical.


    Now Chen Xin''s weather controller is facing the same problem when it was originally controlled by the suvians.


    It''s made, but it''s not practical. It''s even chicken ribs.


    The reason why it has such a great effect now is that on the one hand, it is really the influence of the environment, and on the other hand, it also depends on Chen Xin''s upgrading of the whole machine.


    The effect of system upgrading is really black technology. After the old things of the original suvia era replaced the parts and optimized the structure, they not only improved the efficiency of energy transmission, but also improved the efficiency of converting electric energy into microwave.


    Under the influence of many factors, we have the amazing effect of heating up 12 ¡æ in a short time.


    Therefore, if Chen Xin doesn''t intervene, it can''t be said that there is no possibility of reaching this level only by the research of other people, but it is by no means an easy and easy thing.


    And whether the technology is harmful or beneficial depends on what the people who use it use it for.


    Just like the weather controller, if it is used to improve the environment, it can naturally make a lot of contributions to mankind, but if it is used for war and killing, it can only be a powerful weapon.


    Human beings have already possessed weapons that are many times more powerful than this. Although Chen Xin''s worry is necessary, there is no need to worry too much.


    After keeping this in mind and reminding himself not to use it as a weapon when upgrading the weather controller, Chen Xin continued to focus on how to improve the weather controller.


    The data collected in this experiment is very useful for Chen Xin. Through these data, he not only saw the powerful power of the weather controller, but also saw some shortcomings of the machine.


    According to the feedback from the staff, although the weather controller has undergone a structural optimization and the replacement of old materials before, some new problems are still reflected in this test.


    Some of the internal structure of the machine can still be optimized, and the transmission efficiency of the energy pipeline can also be improved... In a word, there are still many things that can be improved in this machine.


    This is not beyond Chen Xin''s expectation. After all, it is an old thing in the suvia era. Even though Chen Xin has upgraded it twice, this machine still has room for improvement.


    And that''s exactly what Chen Xin''s goal is to continuously optimize and upgrade until this machine can achieve the effect he wants.


    So after the test, Chen Xin ordered other staff to continue to check and analyze the machine and determine a new transformation plan.


    At the same time, he himself worked in the base laboratory with the following chemical researchers to study the chemicals used by the lucians.


    Now that we know the working principle and operation mode of the weather controller, it is not very difficult to analyze what chemicals were used by the suvians in those years and what role they played in the experiment.


    In particular, Chen Xin has detailed records of this chemical in the information they have obtained, and there are still some stocks in the base.


    The materials have been translated and studied for a long time. As for the small amount of inventory, after a long time of storage, it has deteriorated and can not be used, but it can be used to analyze its chemical composition.


    After the analysis of the researchers, the essence of this chemical soon appeared in front of Chen Xin and them.


    "In short, this is a kind of material that uses the physical properties of polar molecules to influence them through microwave, thus rapidly emitting a lot of heat energy. The chemical properties are very simple, and it is also very simple for us to copy them." The researchers don''t pay much attention to this old thing decades ago. After explaining it, they still added: "in fact, the effect of this chemical agent is quite general, and it has certain harm to the environment. We can produce better ones, which are safe, clean and pollution-free."


    Hearing this, Chen Xin nodded slightly, considered for a while, and said: "first, make a batch of test products, I want to see the effect."


    "Well, it''s not complicated to make this kind of thing. It only needs some simple reactions, and there''s no danger. As long as there are enough raw materials, you can take as many as you want." "But how do we use these chemicals?" he asked? Just like the suvians used to fly? "


    "That''s too much trouble, and I don''t think it''s efficient. How about using artillery directly?" Chen Xin thought of one thing and proposed it to the researchers.


    "With guns? Artificial precipitation bomb? It''s OK, too. " Chen Xinyi said that the researchers immediately understood what Chen Xin was saying. Although the commonly used artificial rain bombs are rockets, it is not impossible to launch them with gun tubes: "how big is that?"


    "That''s my job. You just make these chemicals. I''ll deal with the rest." Chen Xin laughs. It''s time for him to do something like this.


    Hearing this, the researchers did not ask, just nodded and said: "OK, give it to us, I really hope to make this machine work earlier, so that we can see the sun on this day."


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While Chen Xin is studying the weather controller enthusiastically, thinking about when the long night in the sky can disperse, another group of people think they are studying some evil weapon.


    These people are not the official of Lucia. Although the weather controller is the secret of the suvia era, few people even knew it in the times of Lucia, it is a matter that most of the official of Lucia know that the government handed over a base with the cold war technology left over from the suvia era to the Chinese.


    They are not surprised by this. The only thing they are curious about is what the cold war technology left over from the Soviet Union is, but most people don''t speculate about weapons.


    But some people are guessing about weapons.


    They didn''t know the specific situation, but they saw the effect of the experiment when they carried out the experiment.


    In just a few minutes, there was a violent wind, which seemed to detonate something in the air. The rolled up snowflakes were blowing around like a blizzard, and the ice and snow in the core area even showed some signs of melting


    Such a scene is not a weapon, and it is not convincing.

    On the mobile base that Chen Xin specially transferred from China, there was a 130mm naval gun.


    This was originally a barrier clearing run for the mobile base, which was used to clear the obstacles that were not easy to clear on the mobile route. However, after Chen Xin made a little improvement, this gun also had the ability of anti-aircraft angle and launching special shells.


    After all, it''s not difficult to make such changes, and the original naval gun has a certain anti-aircraft angle, and Chen Xin just made some adjustments.


    With the gun for launching, the rest is the special shell itself.


    With the efforts of the researchers, the chemicals Chen Xin needed were quickly deployed, and the amount was quite a lot.


    "How did you do so much?" Chen Xin was surprised to see the chemicals in front of him in blue plastic barrels.


    This is really a lot of weight. If it''s used as a shell, Chen Xin estimates that it can do at least a dozen rounds. It''s not a problem.


    "We went to Lucia and asked them if they had any relevant chemical raw materials. They opened a chemical warehouse to us and there were plenty of raw materials in it." The researchers explained to Chen Xin and shrugged their shoulders helplessly.


    Hearing this explanation, Chen Xin could not help but be surprised. However, he soon did not care any more. Instead, he asked the researchers, "is there anything to pay attention to in the treatment of these chemicals?"


    "There is nothing to pay special attention to. They are very stable in nature, not easy to volatilize and decompose, and they are only weakly alkaline. As long as you pay attention to the skin and wash it in time, don''t get it into your eyes." The researchers thought about it and answered Chen Xin.


    It''s basically the same thing as domestic edible soda. There''s really no need to pay special attention to it. As long as you don''t put it in your mouth, there won''t be any problem.


    According to the researchers, Chen Xin is also relieved. In this way, he just needs to simply fill in a special shell.


    And Chen Xin has already been ready.


    With the cooperation of the researchers, Chen Xin quickly completed the charging of the shell.


    He didn''t do much, but only made three. He planned to see the specific effect in the next experiment, and then decide whether to upgrade or mass manufacture.

    "Do you have time now, Dalia? I have something to report to you alone. " Wa Lianjing went up to Dalia and said to her with an excited look


    "Walianjing? What can I do for you Dalia looked at wa Lianjing in surprise, but said to the people beside her, "go ahead. I''ll talk to you about the resettlement later."


    After the people around her left, Dalia asked wa Lianjing, "what do you need to say in private? I can only give you ten minutes. Later, I also made an appointment with the official to talk about material assistance, so if you have any trouble, please speak quickly. "


    It''s not that Dalia is tired of Valentin or something, but that she really has no time.


    With the official reconstruction work, the revolutionary army is also carrying out the reconstruction of the occupied areas and the resettlement of the people.


    However, compared with the government, they are not abundant in both materials and construction forces, so there are many problems in the reconstruction work.


    These days, the members of the committee are also very busy. Everyone has a lot of things to do. As one of the leaders, Dalia is naturally very tired, and her face is a little tired.


    But even so, in the occupied areas of the revolutionary army, there are still many things she needs to deal with, and her time is very tight.


    Without any nonsense and politeness, WA Lianjing directly told Dalia the purpose of his coming to her: "it''s like this. Dalia, before the impact of the meteorite, I used to work in a chemical plant and knew that the government had sealed up a large number of chemical raw materials when the disaster came.


    Originally, I planned to take people to take out that batch of chemical raw materials these two days to see if they could be used. But when I went to the warehouse, I saw that Yanguo people pulled away a batch of chemical raw materials from there. "


    "Yanguo people took away a batch of chemical raw materials?" Dalia felt helpless for a while, rubbed her forehead and said to walianjing, "walianjing, I know you have been worried about the future of the revolutionary army, but you can handle things like this yourself. There is no need to report to me.


    And isn''t it normal for Yan people to pull away a batch of chemical raw materials? The government has reached a cooperation agreement with them. Maybe they just need it? You don''t have to doubt that there''s a conspiracy behind everything. "


    "Originally I thought so, but until someone showed me this." Naturally, walianjing is not a conspiracy theorist. Naturally, he has his reasons and evidence to say so.


    Then he took out an old mobile phone from his pocket, opened a video and put it in front of Dalia.


    "What is this?" Dalia picked up the phone, looked at the picture and frowned: "it looks like wind? Isn''t that normal? It''s windy. "


    "No, it''s not normal. This picture was taken near the base where Yanguo people were stationed." Wa Lianjing explained to Dalia and motioned her to look at it carefully: "because there are Yanguo people stationed there, I sent several people to be responsible for staring there. If there is any movement of Yanguo people, they can inform me in time. This video is taken by them.


    Before the shooting of this video, they said that there was no wind at that time, but they didn''t know what Yanguo people had done in the base. They only felt a sound, but they couldn''t hear it. Then there was a strong wind in the sky, and it was very strange to blow from the middle to the surrounding, as if something had exploded in the middle. "


    "What does this have to do with your story telling?" Dalia also saw what was shown in the video. What wa Lianjing said was like the wind blowing when something exploded.


    The pictures on the video give Dalia a headache. She really doesn''t want to think about the conspiracy of the Japanese, but it''s obvious that the scenes on the video are easy to have bad associations.


    "I think Yan people may be experimenting with something, which may be why they want to get this base from the official hands." Walianjing was not sure what was going on. He made a guess based on what he had learned: "it could be some kind of machine or some kind of weapon. The last time Vasili and I went there, we saw a very huge machine."

 Chapter 553

    If it is before the impact of the meteorite, when it comes to Lucia''s delicious food, it is estimated that many people will answer caviar and big Leba.


    These are indeed two very famous foods of Lucia, especially caviar. In the 12th century, caviar has become a delicacy on the table of European nobles, and is sought after as one of the world''s three delicacies.


    But few people know that before the impact of the meteorite, one third of the caviar in the world was already produced by Yanguo.


    It can be said that with the development of artificial breeding technology, caviar has been pulled down from the altar and become a kind of special food which is just a little more expensive.


    However, after the impact of the meteorite, the bread that can be made with wheat is not extinct, but caviar is really not seen at all.


    But in front of Chen Xin, there is a box of fresh caviar.


    "Is caviar still available in this environment?" Chen Xin looked at the jar in front of him, which was still emitting cold, and even the frost on the shell was not finished. He frowned and looked at the Lucian in front of him.


    This is a banquet organized by Lucia''s government to thank Yan for her assistance during this period.


    Chen Xin didn''t want to come for this kind of thing, but the people sent by Lucia repeatedly asked him to be present, and even said that Lucia''s leaders would also be present in person to thank him, which made Chen Xin have to come in person.


    Originally, Chen Xin thought that it was just a very common way for everyone to have a meal together. After all, in the doomsday environment, he didn''t have the conditions to eat something good.


    But he didn''t expect that lucians were very devoted to turning it into a formal dinner, offering something he hadn''t eaten before the disaster like caviar.


    "In fact, as a traditional food with a long history in China, we still keep a part of caviar." Seeing Chen Xin''s expression at this time, lucians hesitated for a moment and chose a compromise saying: "sturgeon, as a precious species, is also part of China''s plan to preserve species samples before the disaster. What we use today is to dispose of some of the old fish."


    Chen Xin can''t deny this explanation. Although he also knows that it takes more than ten years for fish to make caviar, he has no positive view on this kind of luxury.


    So for those caviar, he has no interest in tasting.


    Just simply took some ordinary food, and went to one side with a few workers of Yan country, said their own things.


    This undoubtedly makes Lucia people feel very shameless, but the purpose of today''s banquet is to thank Yan people, which makes Lucia people can not make any face to Yan people, but try their best to make the situation less embarrassing.


    However, this kind of embarrassment did not last long. Soon after the arrival of Yanguo people, Lucia''s leader appeared.


    His arrival defused the embarrassment.


    Chen Xin met Lucia''s leader, and after a bit of courtesy, they entered the formal part of the banquet.


    Today, lucians prepare the traditional cocktail party and buffet. After all, in this environment, it is obviously not enough to prepare a formal dinner.


    Since there is no way to prepare a formal dinner, the relatively casual buffet is the best choice.


    Today, Lucia''s leaders seem to be in high spirits. They are still having a warm conversation with Chen Xin. Naturally, the topic discussed by both sides is about the reconstruction of the refuge.


    Although Chen Xin almost overturned Lucian''s original plan and redone it, Lucia''s leaders didn''t mind.


    After all, Lucia still depends on the aid of the state of Yan. In the matter of rebuilding the refuge, the state of Yan will also provide technical support and "slightly" make some changes, which is something that Lucia can "happily" accept.


    "Mr. Chen, we need more help from your country for the reconstruction plan of the refuge. Lucia''s strength in infrastructure is really inferior to yours." An official next to the leader put on a very humble attitude towards Chen Xin, saying some things that the leader is not convenient to say, but he can keep a low profile.


    In this regard, Chen Xin responded positively: "as long as there are no domestic opinions on technical assistance, there is no problem in this part. After all, in this big environment, we should all work together.


    If our two countries choose confrontation instead of cooperation, we will lose both sides in this last world, won''t we? "


    "That''s right. In the current environment, if human beings are still trapped in infighting, it can only let us kill ourselves." For Chen Xin''s words, Lucia''s leaders can''t help nodding in agreement.


    "As for specific aid projects, you can send people to talk with China. Although China has given me relevant authority, I am not very good at these. It may be better for you to talk with them about specific terms." Chen Xin didn''t want to argue with Lucian at the negotiation table. He had already made a big head when he discussed with the person in charge about the reconstruction of the refuge, so he simply asked Lucian to talk with the domestic special diplomats, even if he had the authority to make a decision.


    Lucia''s leader didn''t mind, just raised his glass and touched Chen Xin.


    The wine at the banquet is all aged wine. Although Lucia''s most traditional vodka is indispensable, more wine is prepared which makes Chen Xin very surprised.


    "These wines are still from the suvian era." When it comes to this topic, Lucia''s leader cheerfully pulled Chen Xin to say: "the origin of this batch of red wine is Georgia, the hometown of the second generation leaders of suvia. When the iron and steel Comrade took charge of suvia and the Kremlin, he liked his hometown''s wine very much, so he stored a lot of it in the Kremlin.


    Some of them have been sealed up in the cellar of the Kremlin''s underground air defense shelters. Perhaps the original staff have forgotten, and this batch of wine has been preserved until this disaster, when we restart these suvia era shelters and clean up, we can see the light of this batch of wine again. "


    "It''s a legend. If my friend is here, she will be very happy. She likes collecting these wines best." Chen Xin naturally thought of Mo Qingyan and asked Lucia''s leader, "don''t you know if you can give me a bottle? I want to take it back to my friends. "


    "Of course, it''s just a bottle of wine." Lucia''s leader was very generous about this, and after he finished, he approached Chen Xin and whispered to him, "besides wine, I have another interesting news here. I wonder if Mr. Chen is interested in it?"

 Chapter 554

    After the riots and a series of subsequent events, Lucia officials attached great importance to the intelligence collection of the revolutionary army.


    After all, he is the biggest official opponent at present. Even if the two sides have reached a certain intention of cooperation and temporarily suspended the war, it does not mean that the two sides have eliminated their hostility to each other.


    In order to eliminate the influence of the revolutionary army on the official rule as much as possible, after the riot was calmed down, Lucia''s official dispatched elite spies to infiltrate the revolutionary army.


    It has to be said that it''s too easy for elite spies to infiltrate non-governmental organizations. Some of them even joined the Committee and became powerful figures in the revolutionary army.


    In the final analysis, it''s just an organization built by a group of young people with their so-called ideals. There is no strict organizational structure, and there is a lack of talents inside. The infiltrating spies only need to show a little talent to get promoted.


    Under such circumstances, it is too easy for these experienced spies to obtain intelligence.


    These experienced spies didn''t even use any high-tech equipment and intelligence torture means. They just pulled each other to drink two bottles of vodka and got the intelligence they needed.


    As a result, information about the revolutionary army''s internal use of the weather controller being studied by the Yan people as a powerful weapon was soon sent to Lucia''s leader''s desk.


    This kind of thing itself is not worth mentioning, but at the moment of banquet, it is a very good topic.


    And as Lucia''s leader, a former suvia agent, he himself was curious about what the Yanks had achieved in the weather controller project.


    "Did the weather controller experiment explode as some kind of weapon? These guys are really associative After listening to the "interesting" news that Lucia''s leader shared with him, Chen Xin was very indifferent and said, "although the weather controller is indeed a kind of weapon, I think they should pay more attention to why you still have caviar rather than whether we are studying some powerful lethal weapons."


    "Is it because there''s caviar on the dinner menu today?" When Lucia''s leader heard that Chen Xin mentioned caviar, he picked his eyebrows and understood what was going on after a little thought, so he said to Chen Xin, "in fact, we always have caviar to eat, and the slaughtered sturgeon will be made into canned fish to provide more ordinary people with protein and nutrition, Caviar is just an extra product of the process of killing sturgeon


    Lucia''s leaders bypassed the topic of caviar, stressing instead that the fish was not wasted and that more people could eat it.


    Chen Xin did not deny this, but asked curiously, "how do you raise so many sturgeons? Sturgeon that can make caviar is not easy to raise! Especially in the present environment, you have to keep the water temperature and maintain their living environment.


    The most important thing is that feeding these fish requires a lot of food, right? Although I can also understand the significance of ensuring the supply of meat, enriching the variety of food, and ensuring the nutritional balance of the people, why not raise some animals that are easier to feed and have a high meat production rate? Or do some people just want caviar


    "It''s not hard to raise sturgeons." Lucia''s leader laughed and explained to Chen Xin, "in fact, this is still related to your country. Before the disaster, the best-selling caviar in your country squeezed our country''s caviar industry, because Lucia has been using the traditional way of fishing wild sturgeon in the Black Sea to produce caviar, although the quality is very good, But the output is far less than that of the artificially cultured sturgeon in your country.


    So a few years ago, in order to improve the disadvantage of the caviar industry in our country, the caviar manufacturers in our country learned from you and built several artificial breeding factories for artificially cultivating sturgeon to obtain more caviar.


    At that time, in order to keep it secret and maintain the high-quality reputation of Lucia''s wild natural caviar, they didn''t disclose it. Even I didn''t know about it until I went to inspect it. "


    At this point, Lucia''s leader stopped, touched a cup with Chen Xin, drank a mouthful of wine and moistened his throat.


    Chen Xin sipped the wine in his glass and felt the mellow aroma of the wine. At the same time, he continued the topic: "but no one thought that there would be a meteorite impact. Therefore, the whole plan of artificially raising sturgeon to get caviar has died. However, it is obvious that some people are not willing to give up this luxury food and use artificial breeding technology in the name of preserving species, Raised a large number of sturgeon, so that they can eat caviar after the disaster... Right


    In the face of Chen Xin''s conjecture, Lucia''s leaders did not deny: "you know, there are always some people who, for the sake of their appetite and enjoyment, will do things that are difficult for ordinary people to understand or even irrational.


    But it''s not unusual to maintain a luxurious life in this doomsday environment and raise a group of fish with precious food in order to eat caviar, is it? "


    At this point, Lucia''s leader gave Chen Xin a smile.


    Chen Xin picked eyebrows, did not say anything more, just nodded his head to understand.


    Seeing that Chen Xin didn''t talk about this topic again, Lucia''s leader skipped the topic and asked Chen Xin, "speaking of it, have you made any progress in the research on weather controllers?"


    "It''s just a simple start-up test, but the effect is not as good as we expected, so it will cause a little extra impact." Although Chen Xin doesn''t mind sharing the progress of the experiment with Lucia''s leaders, he won''t tell them specific things: "and this kind of thing is very normal. After all, the weather controller itself can be regarded as a weapon, can''t it?"


    "That''s true. After all, it was for the purpose of developing weather weapons that suvia studied weather controllers." Speaking of this, Lucia''s leader shrugged his shoulders and did not deny the fact.


    After the two continued to talk about some topics, Lucia''s leader left because he had other things to deal with.


    Seeing Lucia''s leader leave, Chen Xin becomes less interested in the banquet, so he asks others to stay and eat well. After that, he takes the red wine given by Lucia''s leader and leaves the banquet site and goes back to the base.

 Chapter 555

    After the special shell was made, Chen Xin naturally did not waste time and soon arranged to start the second test.


    In this experiment, Chen Xin did not upgrade the weather controller, but it was still the same as last time, except that this time he will use special shells to spread chemicals in the target area.


    The purpose of this is to obtain comparative data and determine the role of chemicals in the use of weather controllers.


    With such data, it will be a good reference for Chen Xin to upgrade the weather controller to a version that does not require chemicals, or to strengthen the role of chemicals.


    Because this test needs to use the mobile base to launch special shells, Chen Xin came to the mobile base this time and did not stay in the central control room of the base.


    "Academician, the shell is ready. It can be launched at any time. Please give instructions!" The captain of the mobile base is the same as Chen Xin when he returned from Lucia last time. At this time, the mobile base is ready to launch special shells. He is reporting to Chen Xin in the command room.


    Chen Xin nodded and said to him, "stand by and wait for the instructions from the base."


    "Yes When the captain heard what Chen Xin said, he immediately conveyed his order.


    The whole mobile base is now stopping a few kilometers away from the base. When the test starts, the shell will be fired to a predetermined area to detonate in the air.


    When the chemical in the shell diffuses in the predetermined area, the weather controller will be activated on the other side of the base to microwave the target area.


    Compared with the last test, there is only one more shelling process. Therefore, Chen Xin is not worried about whether there will be any problems in the test. For this reason, he comes to the mobile base and wants to see with his own eyes what kind of impact this test will have.


    If the experiment is successful, Chen Xin can start the next part of the weather controller upgrade, and send the current results back to China, so that China can prepare to start the research in this area, and prepare for the future planetary transformation.


    Although planetary transformation is still a long way off, with weather controllers, there is still a foundation. As long as we continue to push forward, Chen Xin estimates that within three years, we will be able to control the global climate, solve the current dust problem, and let the earth see the sun again.


    It''s going to be a long process to let the ice and snow melt and the temperature of the whole planet rise.


    After all, the world''s land is basically covered with snow ranging from a few meters to more than ten meters. In high latitude areas like Lucia, the snow can even reach 20 meters to 30 meters.


    Under such circumstances, if the temperature rises rapidly in a short period of time, it will cause a global flood, which is another devastating disaster.


    You know, now people basically live underground. Once there is a flood, people don''t even have a place to hide.


    So even if we want to restore the climate of Bluestar, I''m afraid we have to slowly figure it out, let the temperature rise bit by bit, let the ice and snow melt slowly, otherwise, the global flood, unless Chen Xin evolved the ark into a floating city, no one can survive.


    However, this kind of thing needs to be considered in the future. Now it is more important to focus on the completion of the experiment.


    Chen Xin adjusted his mind and said to the captain, "ask if the base is ready, can we start the test?"


    Hearing Chen Xin''s instructions, the captain immediately picked up the phone, sent a communication to the base, and soon received a reply.


    "Academician, the base replied that it is ready to start the test at any time." After receiving the reply from the base, the captain immediately reported to Chen Xin and asked him, "do you want to start the test?"


    "Let''s go!" Without hesitation, Chen Xin decisively gave the order to start the experiment.


    With Chen Xin''s command, the command room of the mobile base was immediately busy.


    All kinds of instruments and equipment carried on the mobile base have already been aimed at the target area at this moment, in order to obtain the first-hand observation information in time.


    The apron on one side has already started, and the helicopter has taken off from the hangar and flew to the test area, so as to collect relevant data more closely.


    According to the previous test results, after the weather controller is started, it will cause the local temperature to rise rapidly and cause strong wind, but these helicopters are as close as possible to the test area, hoping to obtain more accurate data.


    The only naval gun carried on the mobile base has been aimed, loaded and waiting to be launched.


    The order of the beginning of the experiment is just to let these people on standby turn into the working state.


    "The last three seconds, three, two, one! Launch With the command of an acoustic emission, the naval gun on the deck of the mobile base gave a roar.


    A special shell blasted out of the gun bore and passed a firelight in the dark sky. Less than a second later, there was also a burst in the target area.


    "Successful launch, the shell has detonated in the target area accurately!"


    "Visual observation of the explosion! Confirm the successful air blast of the shell! "


    "In the process of chemical diffusion, the air concentration in the target area is rising!"


    "Radar observation is normal, all data are normal!"


    One by one, the information was confirmed, and one by one, the report came up. Now Chen Xin, who was standing in the command room to direct the experiment, had the illusion that he was commanding thousands of troops and fighting a crucial war.


    Maybe it''s all the soldiers in the command room who give Chen Xin the illusion, but it''s not wrong to say that this is a war.


    This is a war in which human beings are challenging nature.


    "Alert base, ready to activate weather controller!" Chen Xin picked up the telescope and stood in front of the observation window to see the situation of the target area.


    But in the dark, it''s a luxury to see the situation more than ten kilometers away. All you can see is a silent snow field under the night vision.


    However, when Chen Xin was about to put down his telescope, he accidentally found that there seemed to be several figures in the snow not far from the mobile base.


    This made Chen Xin alert quickly, because he did not arrange anyone to observe on the ground.


    "Lucian?" Chen Xin''s mind flashed over the news that Lucia''s leader had told him before. He called the captain beside him and said to him, "someone is peeping at that position. Bring them back."


    Although the experiment is not a shady thing, the nature of being peeped is different.

 Chapter 556

    "See? Oleg! Do you see that? " In the snow not far from the mobile base, a young Lucia was pointing to the mobile base in front of him and shouting, "they''re firing! Did you see it? Oleg! They fired


    "Shut up, boy, I see it! If you speak a little louder, the people of Yan country will hear you! " The so-called Oleg is a typical strong man of Lucia. He presses the little guy down and signals him to shut up. At the same time, he also stares around alertly to avoid being found.


    However, although Oleg was very careful, the guy he held still struggled and tried to shout.


    This makes Oleg hard to cover his mouth, at the same time, he also feels helpless to this kind of amateur. If the weather is not right now, he really wants to try to take off his socks and put them in each other''s mouth when he was playing torture game in spy school.


    Oleg was a spy and a very good old spy.


    Although he was only in his thirties, he had been lurking in a European country for more than ten years before the disaster. He obtained a lot of important information for Lucia, but he was not found.


    As an elite spy belonging to KGB''s European part, as long as he stays for a few more years, Oleg will be able to pretend to be dead and return home, and then enjoy the leisurely life after retirement at home. Of course, the premise is that he will disappear without exposure.


    In their line of work, exposure means death. Even if they can get away successfully, it will be a very ugly sum in their resume. Some of them will even be disposed of if they cause great losses.


    It is precisely because Oleg knows this that he has been cautious all the time. He only seeks no fault and no meritorious service. That''s why he has been able to lurk safely for more than ten years. He has grown from a little boy''s rookie to an elite with a beard.


    However, just when Oleg was looking forward to making a living, so that he could retire home and get a beautiful wife to live in peace, the meteorite came.


    Of course, KGB couldn''t put these elite spies abroad to die, so it pulled them back before the disaster.


    This is the first time for a spy like Oleg.


    KGB spies lurking in Europe withdrew to China in various ways before the disaster. At that time, KGB headquarters was full of elite. Oleg even met several of his classmates in spy school. He never contacted them after graduation. He thought they had all died.


    However, the happy days did not last long. With all kinds of disasters caused by the meteorite impact, Lucia''s days became very difficult.


    If it had not been for the rest of the world, life would have been more difficult, and Oleg would have regretted why he had to come back to suffer the crime, although he did not regret returning to Lucia.


    Fortunately, the hard times did not last long, and KGB and Lucia officials could not let a large group of elite spies idle.


    They have been re assigned the task, but this time they are not going to target the enemy country, but their own internal.


    Oleg was ordered to sneak into the shelter of a rich businessman and become one of his subordinates. He collected intelligence and information about these rich businessmen and oligarchs, prevented whether they had any conspiracy, and sent it to KGB in time.


    Originally, Oleg''s task had been well performed, and he did not encounter any crisis or difficulties. He gradually gained the trust of the rich businessman.


    But no one expected that the epidemic attacked Lucia, and the whole capital was paralyzed. Oleg had already obtained the intelligence that the oligarchs would secretly promote the uprising, but who thought that the guy who was responsible for transmitting the intelligence actually contracted the epidemic and died soon, which led to the failure of Oleg''s intelligence to be transmitted.


    This made Oleg very upset. If he had taken a little risk at that time and passed on the information, maybe he would not have caused such a big loss in the future?


    Oleg can not assume, but things have happened, as for the later rich with all his subordinates into the revolutionary army, and because of the stubborn resistance was suppressed by the official what has nothing to do with Oleg.


    Because he was assigned a new task, he was asked to join the revolutionary army and collect information about them.


    This is also the reason why Oleg will be here. He showed some intelligence talents in the revolutionary army and was soon entrusted with the task of collecting intelligence.


    The information that Yan people might be testing new weapons was collected by his subordinates, and it was Oleg who told the official this information.


    Today, he just took his hands to observe the experiment of Yan people, but he didn''t expect that the man he brought was so unreliable. He screamed and screamed, and Oleg almost wanted to shoot him.


    Fortunately, after holding down the energetic guy, Oleg and his wife lurked down again. Although it was very cold in the snow, the lurking in less than half an hour was about to freeze him, Oleg still buried himself in the snow as much as possible to avoid being discovered.


    However, just when Oleg felt almost safe, there was a strong wind.


    It''s the strong wind mentioned in the previous intelligence! Oleg reacted almost instantly. After all, he was also a professional intelligence officer. Although the gun fired by Yanguo people on the mobile base just now sounded very powerful, in fact, the caliber was just like that. The wind pressure caused by the shell explosion could not reach this level in any case.


    As he lowered his head, he felt the strong wind sweeping over his head and made a judgment.


    It seems that Yan people are experimenting with something extraordinary! As an old spy''s sense of smell let Oleg aware of this.


    Naturally, he kept this information in mind and prepared to send it back to the revolutionary army and the government.


    Of course, this is not a double dealing, selling two copies of one piece of information, but a necessary means to maintain one''s current identity.


    Don''t think that if he looks rough, he''s really wild. In fact, he should have been eliminated when he was in spy school. Rough is just a disguise.


    Just as Oleg was thinking about this, he suddenly heard a different voice coming from the wind.


    It''s a helicopter! Oleg woke up and almost instinctively bounced from the snow. He looked up to see the direction of the sound. An invisible helicopter was coming towards him, and the snow-white searchlight had come first.


    "Run Oleg called, pulled up the boy on the ground, turned around and ran back.


    However, people can''t run the helicopter. With little effort, Oleg and his men were caught by the Yanguo soldiers who came down from the sky.

 Chapter 557

    "Tell me who you are." In a room temporarily vacated in the mobile base, Chen Xin looks at the captured Oleg and his men, and asks them with a look of being well prepared.


    "We are..." Oleg did not intend to resist, is ready to confess his identity.


    However, before he spoke, the guy on one side jumped up first and yelled at Chen Xin: "we won''t say anything! You won''t know a word from us


    The young man''s fierce action naturally led to the ruthless suppression of Yanguo soldiers standing on one side. The whole person was directly pressed on the table with a bang, and the whole face was pressed on the table by Yanguo soldiers equipped with exoskeletons, which was about to deform.


    All of a sudden, Oleg was embarrassed and helpless, but Chen Xin looked at the two people with different reactions with great interest and showed his interested eyes.


    Chen Xin waved his hand to the soldier to let go of the boy. He turned to Oleg and asked him, "come on, who are you?"


    Chen Xin asked the question again.


    This time, he wanted to say something more, but he was stopped by olegra, and he confessed to Chen Xin: "we are members of the revolutionary army. We are here to have a look. There is no malice! It''s all a misunderstanding! "


    "Uncle Oleg?" He looked at Oleg in disbelief and seemed very surprised that the uncle, who usually looked brave and resolute, could say everything without backbone.


    "Shut up, it''s nothing to hide!" Oleg yelled at the boy, and then respectfully said to Chen Xin: "we are not official spies. We just heard that there was a strange noise here, so we just came to have a look. There is really no malice.


    And we also want to thank you for your help. If you didn''t help us treat those infected people, I''m afraid we should all be sick now. "


    Chen Xin noticed that when Oleg said this, he gave himself a special wink.


    "Not an official spy? Well, you don''t really look like spies. " Chen Xin nodded playfully, and then said: "OK, since you are not spies, I will not embarrass you. You take this young man to get something to eat. It seems that he hasn''t had a few full meals recently?"


    Hearing something to eat, the expression on his face was obviously shaken. He wanted to firmly refuse, but the hunger in his stomach soon disintegrated his will to resist.


    In the boy some don''t want to, but shy attitude, he still followed the side of the Yan soldiers left the room, was taken to the canteen.


    After the boy left, Chen Xin put away his smile and looked at Oleg in front of him. At this time, Oleg''s face became more serious. Although he was still respectful, he could not see the rough feeling, but showed a kind of capable look.


    "So... Are you from KGB?" Chen Xin looked at Oleg and asked him.


    Oleg did not admit it, but nodded his head slightly.


    Chen Xin was clear about his attitude, and he didn''t say much. He just said to himself, "so you''re here to watch us? Because the high level of the revolutionary army thinks that we are testing some powerful weapons? "


    "We really have no malice. The high level of the revolutionary army didn''t think you were testing any powerful weapons. We just came to have a look." Oleg is still dripping, but the expression on his face seems to be saying that what he is saying now is irony.


    Of course, Chen Xin understood what he meant, but he didn''t find it strange. After all, he had learned about it from Lucia''s leaders before, and it was no surprise that someone peeked at him when he was conducting his own experiment.


    As for saying that the revolutionary army suspected that they were studying some powerful weapons, Chen Xin could only smile.


    Weather controller is a kind of weather weapon. In terms of its power alone, it may not be very lethal, but its scope of influence and consequences are far better than most of the weapons possessed by human beings. The only one that can match it may be nuclear weapons, the ultimate weapon.


    In fact, if Chen Xin does not study the weather controller with the idea of changing the overall climate of the blue star and letting mankind see the sun again, but takes it as a powerful weapon, I''m afraid he can kill all the people in the capital of Lucia with the weather controller now.


    Of course, the facts belong to the facts, but Chen Xin has no obligation to explain to the revolutionary army. As for their misunderstanding and hostility, it only makes him feel that these lucians do not know good or bad.


    At the moment, their survival depends to a large extent on the assistance provided by the state of Yan to Lucia, whether it is medical treatment or food, or the construction of shelters.


    If Yanguo cuts off the aid to Lucia at the moment, or simply agrees to cooperate with the government to flatten the revolutionary army, these people will have no chance to live.


    But at the moment, they don''t know how to be grateful. On the contrary, they are full of hostility, exclusion and suspicion towards the people of Yan, which makes Chen Xin very uncomfortable.


    If it wasn''t for the fact that these people could continue to bring survival points, he would have let Lucia''s officials get rid of the so-called revolutionary army.


    After all, as the person in charge of Yan state''s aid project to Lucia, Chen Xinshang has considerable authority. If he wants to, he can completely cut off all the supplies of the revolutionary army, and it is not impossible for him to send someone to cooperate with the official to suppress these revolutionary army. But after serious consideration, Chen Xin did not do such a thing. However, he was obviously not in a good mood. He said to Oleg in a low voice: "I don''t care whether your revolutionary army has malice or not. Your behavior of peeping at our secret experiments can be regarded as a provocation to our country and a theft of secret technology. I hope this is the last time, and there won''t be another time, otherwise... Don''t blame me for being rude to you." Chen Xin is not a person who is used to speaking harshly, so what he said is a relatively mild threat, and he can''t hear any lethality. But Oleg is not the ordinary people who don''t know anything about the revolutionary army. He clearly knows what kind of deterrence is hidden under Chen Xin''s seemingly mild words. If those people of the revolutionary army who are not very smart want to use force against the country or continue to provoke, Oleg clearly knows that even if there is no official intervention, the power of the people of the country now in the capital of Lucia is enough to easily flatten the whole revolutionary army. Thinking of this, he busily promised: "I promise there won''t be another time!" Chen Xin couldn''t deny the validity of this guarantee. He just shook his head and didn''t say much. He obviously didn''t like Oleg''s guarantee. www.novelhall.com , the fastest update of the webnovel!

 Chapter 558

    To send Oleg and his men away from the mobile base, Chen Xin is still in a bad mood.


    This unwillingness to repay the people''s kindness has always been hostile to the people of Yanguo, although it has been widespread in western countries before the disaster, especially their media''s years of propaganda to discredit Yanguo, leading to prejudice has long been engraved in their people''s bone marrow.


    At the beginning, Chen Xin didn''t mind Lucia''s hostility to Yan country. After all, it''s other people''s ideology. There''s no need to watch them live for a small matter.


    Although Chen Xin claims to be a man with a good temper, no matter how good he is, his temper is limited.


    He felt that he could no longer indulge the revolutionary army in the capital of Lucia. Whether they were real revolutionaries or not, Chen Xin felt that it was time to solve these people and the problems they brought.


    Thinking of this, after Chen Xin returned to the base, he did not go to see the test report for the first time. Instead, he called the commander of the former reinforcement force.


    Because he has been staying in Lucia, and now he controls the base, he has been temporarily appointed as the safety director of the base. In addition to the special forces he originally brought, he also has another team of Yanguo soldiers.


    "Academician, are you looking for me?" The commander came to Chen Xin''s office and saluted him in a straight line. After saying hello, he asked Chen Xin what he was looking for.


    "Is there anything wrong with the security of the base recently?" Chen Xin asked him without feeling happy or angry.


    The commander had heard about catching two lucians before he came, so he quickly apologized to Chen Xin and said, "sorry, academician! I neglected the security work in the test area! I''m willing to accept punishment. "


    "A little thing, not much." Chen Xin waved his hand. Although this kind of thing can be investigated for responsibility, it is really unnecessary: "in such a large experimental area, unless I give you another regiment, otherwise you have to protect the base and protect the people in your hands. How can you empty the entire experimental area?"


    Hearing Chen Xin say so, the commander put down some worries in his heart, but at the same time, he was also a little nervous.


    After all, Chen Xin didn''t punish him for this, it must be something else he needs to do.


    Sure enough, Chen Xin said: "although this incident is not a big deal, I don''t want the so-called revolutionary army to cause us any more trouble. Later, you can contact Lucia and tell them about this incident, saying that I hope they can solve the revolutionary army issue as soon as possible."


    "I''ll get in touch? Wouldn''t it be better for the base staff to contact us? " The commander didn''t understand that there were no special liaison personnel in the base. Chen Xin asked him to contact Lucia, which was unreasonable.


    But Chen Xin did not intend to explain, just looked at him.


    "Guarantee to finish the task!" The commander was excited by Chen Xin''s look and stood up quickly and yelled.


    Chen Xin nodded with satisfaction and said to him, "if you understand, go ahead. I hope to receive the result as soon as possible."


    "Yes, academician!" The commander answered loudly, then turned and left Chen Xin''s office.


    Although he doesn''t quite understand why Chen Xin has such an attitude, the commander who clearly understands Chen Xin''s importance to the country knows very well that Chen Xin is just changing his attitude and hopes that Lucia will officially solve the revolutionary army. Even if he plans to let the army of Yan country do it himself, the country will only call in follow-up support or persuade him not to use such a radical way, It will not stop Chen Xin from dealing with the revolutionary army.


    Even for the sake of Chen Xin''s safety, if necessary, it is within the acceptable scope of the high-level of Yanguo to wage war with the official of Lucia.


    In this regard, as the security director of the base, he has received a clear instruction from China, and the highest premise is Chen Xin''s safety.


    While the commander went to carry out Chen Xin''s instructions, Chen Xin in the office finally opened the test report to understand the details of the test.


    This test is not much different from the last start-up test.


    There was no difference between the two experiments, except that the exposure time was extended to 15 minutes and chemicals were projected into the target area.


    This is mainly for comparison, so as to confirm the variables in the test process and the influence of these variables.


    The results of the experiment did not disappoint Chen Xin and the researchers, which clearly reflected the results and the main factors affecting the results.


    The first is the exposure time. This time, due to the extension of the exposure time and the pre arranged detection balloon, the staff can more accurately record the temperature change during the test.


    This also makes Chen Xin can intuitively see that with the extension of irradiation time, the temperature does have a significant rise.


    But also, when the temperature rises to a certain extent, it rises more and more slowly.


    In short, the whole temperature rise is not a straight line, but a curve with large radian. The closer to zero, the more gentle the rise of this line.


    This explains why the temperature rise was so exaggerated before. When it was 100 degrees below zero, it was 12 ¡æ in three minutes, but when it was close to zero, it didn''t rise by 5 ¡æ in three minutes. And this result was obtained under the influence of chemicals. By comparison, Chen Xin also found that when the temperature is very low, the spread of chemicals can not play a very good effect. This kind of chemicals seems to have a better effect only when the ambient temperature is relatively high or close to zero. As for why we can draw such a conclusion, we only need to calculate the temperature change curve of this time and the temperature change curve of last time, and then compare them, then we can get the difference. After all, the first half of the two curves basically coincide, but the second half of the temperature curve has a small jump, which can explain the problem. And understanding these data, Chen Xin is also aware of the current situation of this weather controller. In short, it may still not be of any use, unless Chen Xin continues to invest in its survival and further upgrades. Otherwise, this machine can''t play a big role now. Although it can make the local temperature rise, the effect will be significantly reduced when it is close to zero. In the range of zero degree, the most common cause of temperature change is strong wind. As for rainfall and other weather changes, we must at least let the temperature reach above zero in order to have a more significant effect. www.novelhall.com , the fastest update of the webnovel!

 Chapter 559

    Comparing the two tests, it can be seen that although the weather controller is useful, it is not very obvious in the current environment.


    From the test results, the stage of good effect of using weather controller alone is the stage of relatively low temperature. After the temperature rises, the effect of weather controller decreases year on year.


    However, the best working curve with chemicals needs the ambient temperature at least above zero. The irreconcilable boundary between the two is a dilemma.


    Although it is not impossible to use the weather controller to irradiate the target area first, and then broadcast chemicals to maximize the effectiveness of the weather controller after the temperature rises, it is still not an efficient way.


    In other words, it''s not a way to work quickly.


    According to Chen Xin''s assumption, the weather controller should be able to quickly change the weather in a certain area, quickly form precipitation and strong winds, and affect the dust in the atmosphere.


    However, in the current situation, this weather controller can only make the local temperature rise in a short time.


    Although the weather is controlled by controlling the temperature, the water vapor in the air has already condensed into ice in the environment of more than 100 degrees below zero, and the air here is no less dry than that from the desert.


    In this case, if local warming wants to cause rainfall or snowfall, it must at least maintain this temperature, let the snow on the ground melt and evaporate, make the air humidity reach saturation, and form rainfall.


    But in this case, it is necessary to use the weather controller to irradiate the target area for a long time.


    However, the weather controller is not a searchlight or heater. It can be turned on for a long time. The power consumption of this big machine is equivalent to half of the power consumption of the capital of Lucia.


    Long time start, even if Chen Xin they have isotope generator, it is difficult to bear such a large power consumption.


    And more importantly, such a huge power consumption and converted electromagnetic waves also have a heavy burden on the machine itself.


    In the last test, there was no problem because of the short start-up time, but this time, the running time of the machine was prolonged, and it was obvious that some parts of the machine were overloaded.


    Although there is no problem for the time being, and it can be sustained by a little longer, no one can guarantee that there will be no problem.


    Although such a large machine is broken, one or two parts may not affect the overall operation, but no one really wants something to happen.


    Therefore, after the completion of this test, the staff put forward to limit the use time of the weather controller, and try to avoid using it for too long.


    In fact, if it is in the environment before the disaster, short-term irradiation and a few degrees temperature rise are enough to achieve the goal. There is no need to irradiate the target area for a long time to make its temperature rise to above zero as it is now.


    Therefore, after this test, the staff need to further overhaul the whole weather controller, and replace some vulnerable parts again. At the same time, according to the data of the two tests, they need to consider how to further improve the machine.


    This time, Chen Xin completely left the improvement work to the staff at the bottom to deal with, while he himself was considering how to reduce the weather controller, which is still a giant, to be installed on the mobile base.


    Through these two tests, Chen Xin has also found out the limit of this weather controller.


    According to the data obtained so far, when the radiation range of this machine is reduced to the minimum, the projection distance can reach 50 km, and the affected area is about a circle with a radius of 5 km.


    This area looks very large, but if you look at the actual result, that is to create a rainfall in some areas.


    Of course, we can expand the influence area by adjusting the projection range of the weather controller, but generally speaking, it is nothing more than expanding the small range to a certain range.


    If only such performance, of course, can not meet the needs of Chen Xin, or even the needs of changing the weather in the current environment.


    Therefore, to improve the performance of the weather controller and expand its scope of influence is what we need to do now.


    As for reducing the size, installing it on the mobile base, so that it can move and affect the weather in more areas, it is a further matter.


    Now, Chen Xin has left the task of improving the performance of the machine to his staff, while the task of reducing the size is up to him.


    Generally speaking, the weather controller can be regarded as a large microwave transmitter. One of the main reasons for its huge size to occupy the whole base is that it needs to convert electric energy into electromagnetic waves. However, in terms of the technology of the suvia era at that time, it can only make such a large one.


    In fact, even with the current technology, the machine can be made smaller, but on the whole, the weather controller still can not be reduced to a mobile base.


    In terms of human science and technology, it will take decades for Yanguo''s scientific research speed to achieve this even before the disaster. Because one of the most critical factors is that if you want to influence a large enough range, the power of the machine must be large enough, and the simplest way is to make a large one. But it''s easy to make a large one. It''s hard to keep enough power even if you want to reduce it. All the factors involved in this process may require the improvement of the overall level of science and technology in order to reduce the volume. However, for Chen Xin, this is relatively simple. Everything is left to the omnipotent system. As long as there is enough investment in survival, the system will always make you satisfied. In fact, if Chen Xin is willing to survive, he can even reduce the weather controller to the extent that it can be put in his pocket. Of course, the cost of survival is astronomical, even more than the cost of Chen Xin''s directly upgrading the weather controller to a planetary reformer. Chen Xin certainly won''t think about this kind of thing. Even if he wants to save his life to achieve the goal of reducing the weather controller, he can''t be so reckless. From the current situation, in order to reduce the volume of the weather controller, the first thing we need to remove is its original huge power supply structure. The nuclear power plant originally built by the suvians has now been replaced by isotope generators, but isotope generators do not need the bloated power supply organization that originally supported the nuclear power plant. So this part can be removed. The remaining part is the optimization of structure and materials. The last optimization upgrade can only be regarded as a preliminary optimization. This time, it will be a further optimization. www.novelhall.com , the fastest update of the webnovel!

 Chapter 560

    The upgrading of weather controller is obviously not a work that can be completed quickly in a short time.


    In fact, it took a few days for the staff to summarize the problems exposed in this experiment and submit them to Chen Xin in a report.


    However, although it took a few days, the information collected and sorted out by the staff was also very comprehensive. They not only marked out all kinds of problems, but also gave the solutions they could think of.


    This includes not only the modification of the existing structure of the weather controller, the replacement of parts and other suggestions, but also the transformation of power supply lines and other aspects.


    It can be said that with this report, Chen Xin can upgrade the weather controller again without thinking at all, and the effect is even better than his own.


    For Chen Xin, he doesn''t have any boring things like the face of a leader. He has to point out any mistakes in the reports submitted by his subordinates, and modify them to show his ability and authority.


    In today''s environment, everyone has become pragmatic and efficient. Although the bureaucratic articles like those in the past can not be said to be completely extinct, they basically can not find the soil for survival.


    And without all this red tape, efficiency is also visible to the naked eye.


    However, after Chen Xin got the report and read it in detail, he did not immediately start to upgrade the weather controller. Instead, he asked the staff to make a renovation plan according to the report.


    This time, Chen Xin does not plan to use the system upgrade to complete the transformation and upgrading of the weather controller, but plans to let the staff complete all the transformation according to the report they provide.


    Of course, it''s not that Chen Xin wants to be lazy, but that some staff members suggest to him that he leave this matter to the people under him instead of completing all the work himself.


    Because the concept of the system is fuzzy, in the view of Chen''s new staff, it is Chen Xin who has completed all the transformation and upgrading work before.


    Although this makes the staff feel that Chen Xin is really powerful and his ability is exaggerated, correspondingly, they feel that they can hardly play a role.


    In this case, naturally, someone would like to be more involved in the project, rather than just a tool person to fill the gaps for Chen Xin.


    What''s more, the staff can''t copy Chen Xin''s ability. They can''t quickly upgrade the whole machine by themselves, and they can''t be familiar with the weather controller. They can copy another one in other places.


    With Chen Xin in, of course, we can expect Chen Xin to give full play to his ability to do all this. But what if Chen Xin is not there? If he suddenly has something to return to, who can take over this big business?


    If Chen Xin is suddenly gone and something comes back to China, the weather controller will come to a halt, which is absolutely undesirable.


    What the country needs is not only a usable weather controller, but also a master of the whole weather control technology. This is not what Chen Xin can do simply by upgrading the weather controller itself.


    He must let these staff conduct in-depth research on the weather controller, participate in every process of its upgrading and transformation, and even let them complete the upgrading and transformation themselves. Only in this way can these staff understand the weather controller enough, understand its structure and principle, and make it possible to duplicate one in other places.


    So this time, Chen Xin did not participate in the upgrading of the weather controller. As a leader, he just assigned tasks to the staff under his opponent, so that they could give full play to their ability and initiative to complete the task. At the same time, Chen Xin also hoped to see what surprise they could bring him.


    In fact, even without Chen Xin, these workers are also the top technicians in Yanguo. They have studied the weather controller in many aspects before. Now they don''t know it completely, but at least they are basically familiar with it.


    Therefore, some of the staff are very bold to dismantle the most critical core parts of the weather controller.


    There was no movement here. When the weather controller was built in the suvia era, the whole core part was sealed. For so many years, even the maintenance was not carried out.


    Chen Xin''s two previous upgrades had no impact on this area, so that when the core shell of the weather controller was disassembled, someone found the slogan written inside the machine by the original builders.


    Looking at these slogans full of the flavor of suvia, Chen Xin, who is inspecting the construction site, even has an indescribable feeling. It''s like seeing a veteran who still sticks to his post and defends his motherland even though the country has perished.


    Although Chen Xin knows that this is his own illusion, and these slogans of the suvian era are just historical relics, after some consideration, Chen Xin still decides to let people dismantle the parts that can be disassembled, and then give them to Lucia''s official.


    After all, in a sense, this is a precious historical trace for Lucia.


    In addition, for the core part of the weather controller, Chen''s staff only expressed their disgust¡° Such an old structure, even if it was designed in the era of suvia, is it too old-fashioned? Didn''t the suvians think about upgrading it and using a new structure? This kind of design was out of date at that time, wasn''t it A staff member while dismantling the core components of the weather controller, while spitting to colleagues. Make complaints about Tucao is not very popular with colleagues, but the same old mood is used in the design of the core of the weather controller. "This design was not outdated at that time, but it was not what advanced. It''s strange that the scientific and technological forces of suvia at that time should not have designed it like this. The technology they mastered could support them to adopt more efficient structural design. Why should they design it like this? " Obviously, although colleagues are also thinking about this issue, their concerns are not the same¡° Maybe it''s a request from the top of suvia? You know, in those days, the government of suvia often interfered with the progress of scientific research and spent money on scientific research. " The staff showed their helplessness¡° Also, mature and stable technology is always better than experimental technology that does not know the result. " Colleagues can only think so at this time, after all, this is not the focus of their attention. www.novelhall.com , the fastest update of the webnovel!

 Chapter 561

    In order to meet Chen Xin''s research and transformation needs of weather controller, a transport plane will fly from China almost every few days.


    The aircraft mainly transports a variety of customized parts and related materials. Although Lucia can also provide materials, at present, Lucia''s official situation is basically at the end of its tether.


    With the help of Yanguo, the situation of the epidemic has improved a lot and has been controlled temporarily. However, Lucia''s domestic industrial production is basically paralyzed.


    In addition, Lucia herself is also carrying out the reconstruction work of the refuge. Even if she can provide materials for Chen Xin and them, she can only provide some basic building materials, which is not enough.


    Therefore, some important mechanical parts and raw materials can only be transported by air from China.


    Fortunately, the air route has been gradually unblocked. With the existence of air filters and electric engines, most of the aircraft have been able to take off again.


    Because of this, Chen Xin can enjoy the treatment of having a special plane to deliver goods every few days.


    In addition to the parts needed by Chen Xin for the modification of the weather controller, there are also follow-up assistance materials provided to Lucia.


    Although most of these materials are emergency food, which is used to alleviate the current food problems in Lucia, some of them are related equipment and building materials needed for the reconstruction of the capital shelter in Lucia.


    Chen Xin is also very concerned about how much survival he can get, so after busy with what he is doing, Chen Xin comes with a batch of supplies to Lucia''s refuge, which he has visited once before.


    Compared with the war damaged appearance when Chen Xin came last time, the refuge now looks much better.


    Although the construction is in progress, there are busy workers and flying dust everywhere, it can be seen that the original damaged areas have been treated and repaired.


    This is not what Chen Xin saw last time as an independent private refuge for the rich, but a new look after connecting with the surrounding residential areas and being used as a functional area.


    This is also a place where Chen Xin revised the design drawings of lucians and adjusted their original plans.


    Although the lucians originally planned to use this place as the core of the shelter after reconstruction, they didn''t want to expand it. They even planned to use the original shelter after it was repaired.


    Chen Xin doesn''t plan a shelter like this, so he specially modified the design drawing to enlarge the area and expand it into a functional area for 6000 residents of the whole shelter.


    In addition to the greenhouse and dining hall specially emphasized by Chen Xin, the main expansion here is the private home theater, library and gym prepared by the rich for themselves.


    Originally, these were luxury facilities for private enjoyment. In the original planning of lucians, they were also preserved here, only for a few people.


    But after Chen Xin''s adjustment and expansion, these places have become public facilities, which can meet the needs of more people.


    Chen Xin also plans to design a large public bathroom and an indoor swimming pool, but these two points have been canceled in consideration of Lucia''s need to save water and protect personal privacy, and replaced by independent bathrooms for each household.


    It is worth mentioning that although it is an independent bathroom for each household, Chen Xin did not design stoves for each household. All hot water is provided by the heating facilities in the functional area.


    And these heating facilities are the ground source heat pump assisted by Yanguo.


    They not only heat the entire shelter, but also provide hot water for all.


    When Chen Xin arrived, Lucia''s workers were laying heating pipes on the floor. Although the main machine of the equipment had not yet arrived, these heating pipes could be laid first.


    "How do you make it? What are these black things? " Chen Xin, quite curious, watched the workers bury the orange hose in the groove of the black mat on the ground, and couldn''t help asking them.


    The worker looked up at Chen Xin and the official Lucia who accompanied him. Seeing that the official nodded, he explained, "these are the heat insulation mats made of waste tires. They can play the role of heat insulation and heat preservation. Under them are the moisture-proof materials. Next, you just need to bury the heating pipes in the grooves that have been opened in advance, You can lay the floor on it. "


    "Sounds good, but used tires?" Chen Xin tilted his head, did not know what he thought of, and suddenly laughed.


    Naturally, Lucia''s officials were very curious. As they continued to inspect Chen Xin, they also asked Chen Xin, "Mr. Chen, what were you laughing at just now?"


    "Nothing. I just think that rubber can only be produced by industry now. Natural rubber has disappeared. Even waste rubber tires should be very important resources, right?" When Lucia''s officials asked, Chen Xin answered his question.


    Just for this point, Lucia''s officials had no choice but to say: "before the disaster, recycling waste tires to make this kind of insulation mat belonged to resource recycling. At that time, Lucia did not lack of rubber. Whether it was petrochemical production of synthetic rubber or import of natural rubber, Lucia could get enough resources, but now, even waste tires, It can only be used sparingly. "


    "Well, which country is not like this now?" When Chen Xin heard Lucia''s sigh, he could not help sighing: "before the disaster, human beings always said that resources were scarce, but they did not pay attention to saving. Every year, a lot of resources were wasted, which not only wasted but also polluted the environment. Innumerable people have advocated saving resources, but few people really pay attention to it. Now it''s better to save all materials. Anyone who dares to waste resources in such an environment is really looking for his own death. " Lucia''s officials agreed. Different from the fact that the government of the Republic of Yan had prepared for the disaster with the help of the whole nation, Lucia had also made preparations, but Lucia''s basic and official control over the people could not make them like the government of the Republic of Yan. In addition, the problem of epidemic disease made the whole country in chaos. Now they are really worried about the problem of resources. For example, a considerable part of the building materials used in the reconstruction of the refuges were recovered from some warehouses owned by the oligarchs and the rich. This is also the reason why Lucia''s official design for the reconstruction of the refuge was so tight. On the one hand, they wanted to eliminate some hidden dangers; on the other hand, they really did not have the resources to carry out drastic reconstruction. If there were no supplies from Yanguo, it would be impossible for lucians to agree with Chen Xin''s revised design. www.novelhall.com , the fastest update of the webnovel!

 Chapter 562

    Yanguo''s aid to Lucia''s reconstruction of the refuge mainly focused on some equipment and scarce materials.


    For example, the ground source heat pump used in the shelter is the same as the core of the energy tower, which is transported from Yanguo by air, and some cold proof and heat insulation materials used in buildings also rely on the assistance of Yanguo.


    Of course, the amount of construction material assistance in this part is not very large. After all, the transport capacity of aircraft is precious. It is impossible to transport too many construction materials by aircraft. Only the scarce materials and related equipment can be transported by aircraft.


    Besides airplanes, Yanguo is also considering opening up the railway line from China to Lucia.


    It''s just that this route is too long. Even if Chen Xin had successfully arrived in Siberia by railway before, they would have to take the same length of that route to reach the capital of Lucia.


    Thousands of kilometers away, even if the nuclear power train can run so far, the maintenance of the rail is also a big problem.


    Therefore, although Yanguo is considering this matter, and Lucia is also actively cooperating and making efforts, the smooth railway transportation is still a distant thing.


    This also led to the fact that the transportation of goods and materials between Yanguo and Lucia can only be carried by air at one time.


    However, this has little impact on Chen Xin. The transformation of the weather controller has domestic support. Whatever materials or parts are needed can be basically guaranteed to be delivered in time. Even if something is temporarily in short supply, it is not impossible to send a plane to fly.


    As for the upgrading of the weather controller, because of the domestic support, although Chen Xin did not intervene in this upgrading, the progress is still very smooth.


    The parts with problems in the two tests have been replaced, some of them are old though they have no problems, and the parts that Chen Xin did not replace in the two previous upgrades have also been replaced this time.


    In addition, for the core part of the parts, the staff through the connection with the domestic, re drafted a new structure, intended to replace the core parts of the weather controller as a whole.


    After replacement, the core part will have higher energy conversion efficiency and load capacity, can withstand higher current input, and can also convert more energy.


    On the whole, Chen Xin is very supportive of this scheme. Although he can solve the problem with his hand, all the parts involved in this scheme are processed and produced in China, and then transported to Lucia by transport plane for on-site installation.


    In fact, before placing an order in China, Chen Xin also mentioned that these parts can be processed in Lucia''s side, or even directly with the original old parts.


    However, the domestic side, after some consideration, chose to let the domestic factories produce.


    Chen Xin can guess some domestic considerations, so he didn''t say much about it. After all, at the beginning, he planned to let the staff complete all the work, and didn''t want to interfere with the system upgrade.


    In addition to that, researchers in charge of chemicals are also trying to improve the formula that lucians left behind.


    After all, the previous experiments also showed that chemicals need to be above zero to have a better effect, but now in this environment, the temperature above zero is very difficult to achieve, so improving chemicals to make it work below zero has become a method that will inevitably be tried.


    Chen Xin didn''t intervene in this aspect. He just improved the structure of the special shell so that the chemicals contained in it could spread better.


    According to Chen Xin''s prediction, if there is no accident, the domestic parts will be delivered on time. According to their current progress, all the renovation work will be completed in about a month, and the third test of weather controller will begin.


    After the third test, Chen Xin will use the system upgrade again.


    This time, Chen Xin is going to adjust the weather controller directly to the extent that it can directly affect the current environment.


    This is not an easy thing, because at present, the ambient temperature in any region of Bluestar is dozens of degrees below zero, and the temperature in a region near the frigid zone like Lucia has dropped to more than 100 degrees below zero. If you want the weather controller to work directly in this environment, it is really only possible to rely on the black technology blessing provided by the system upgrade.


    After all, in this kind of environment, if you want to raise the temperature of an area above zero, I''m afraid it will be easier to drop a nuclear bomb directly.


    Of course, in that case, it is not to control the weather, but to create disaster directly.


    A completely uncontrollable nuclear explosion cannot be used as a means to adjust the weather.


    Although a nuclear explosion can release huge energy and generate enough heat in the explosion area in a very short time, it can not have much impact on the weather.


    Unless the equivalent is enough and air explosion is used to blow up the dust in the atmosphere directly.


    It''s just that this method is just talking, not to mention the radiation problem caused by the air explosion of nuclear bombs. Even if we use relatively clean hydrogen bombs and want to blow open the atmosphere, the nuclear explosion equivalent used must be more exaggerated than that of Czar bombs.


    No one can predict the impact of such a nuclear explosion. So it can only be an assumption, and no one will really try it. It is more feasible to wait for natural dust fall than to rely on nuclear shock wave to disperse the dust in the sky. In fact, if it had not been for the sudden eruption of volcano dopa, which caused a huge amount of volcanic ash and eruptions, by now, the dust in the atmosphere would have dropped a little, and the sky would have recovered some visibility. Thinking of these, Chen Xin always has an idea and impulse to fly to the sky to have a look. Although the last time the transport plane was modified, it flew up in the past, but it didn''t see anything at that time and didn''t understand the situation carefully. It flew up and came down soon. But now Chen Xin''s idea is different. This time, he wants to fly up as much as possible to find out how serious the dust distribution in the atmosphere is. Even if the weather controller can be used, the impact on the dust in the atmosphere will not be realized in a short time. Chen Xin can''t wait to see if there is a faster way to work. Although he also knows that it''s a good way to upgrade the weather controller, sometimes people can''t wait. www.novelhall.com , the fastest update of the webnovel!

 Chapter 563

    With the full support of China, the upgrading of the weather controller was completed as scheduled, and the third experiment was prepared step by step.


    As for Lucia, their work on the reconstruction of refuges is also very smooth. Three of the five refuges in the plan have been completed, and the construction of the other two are coming to an end. Only the last finishing work is needed to complete all the construction.


    In terms of the treatment of epidemic diseases, with the medical aid and materials provided by Yanguo, the infection situation has been effectively suppressed, and the infected people have also been effectively treated. Although the development of vaccine still needs to wait for some time, the overall situation is gradually getting better.


    On the surface, it seems that everything is going well, and the situation in Lucia''s capital is gradually improving.


    But the undercurrent is still surging, it seems that there are always some people are not willing to live a plain life.


    In fact, people''s desire can never be satisfied. For ordinary people, it is already a very happy life to be able to eat, dress and warm, have little savings, and not be troubled by various life problems. Even if there is some pressure in life, it is enough for a family to be happy together as long as they can live well.


    But for some people, the material living conditions can be secondary to them, the emotions brought by relatives, friends and family are also secondary, and even everything that satisfies their personal needs and desires is secondary.


    Only when he stands in a high position and dominates others, can he really be intoxicated physically and mentally, willing to devote himself to it and give all he has.


    In fact, such people are not uncommon. There are always some people around us who are willing to sharpen their heads and climb up. They can do everything for the sake of drilling.


    If only before the disaster, we all live an ordinary life, this kind of person is no more than utilitarian.


    However, in today''s disaster environment, this kind of people''s practice and at all costs has completely changed.


    Stable social order is seen by them as an obstacle to their ascent. The stable life of the people is meaningless without their rule. The measures taken by the rulers to improve people''s livelihood are regarded by them as a bid to win the hearts of the people


    In the eyes of these careerists, if they do not sit in the position of supreme power and rule everything, no matter how happy the people live, it will only become an obstacle to their power.


    Because only in adversity and suffering, people will need someone to lead them, people will want someone to overthrow the existing rulers.


    What the careerists need to use is this emotion to overthrow the original ruler and let themselves ascend the position of a new ruler.


    It''s very unfortunate for the people to have careerists. However, in Lucia''s capital, all kinds of careerists come on stage one after another when everyone should unite to fight against the disaster. They make a mess of everything and make everything that should not be so bad very bad.


    What''s more unfortunate is that while everything is getting better, some people want to make trouble for their own ambition.


    But this time, the people who caused trouble are far more brilliant than those before.


    There was caviar at Lucia''s official banquet for Yan people before, which was not a big deal. Although it was really out of date, it didn''t say that it would bring much problems.


    However, under the instigation of intentional people, it was spread in the revolutionary army that the officials fed the fish the food they should have provided, so that the officials could have caviar to eat.


    Such a rumor is of course nonsense, but it is difficult to refute and falsify.


    Because caviar did appear at the official banquet at that time, and the official itself has always provided caviar, but these caviar are only for the official high-level, which is a very luxurious and rare enjoyment.


    In fact, this is not too much. There are also special supplies in the state of Yan. Chen Xin can get such supplies every month, including meat, eggs, fresh vegetables and milk. For ordinary people, this is absolutely a luxury in the end of the world.


    But if we deprive ordinary people of their food rations to make use of these luxuries, we are exaggerating.


    Because people may not be able to eat what animals can eat.


    If you think about it with your head, you can know that the fish feed used for fish farming is obviously impossible to be used for people to eat, and it is also impossible to say that the food originally provided for people can be used for fish.


    But most of the time, people are reluctant to think, and they are very easy to be incited and coerced.


    At the beginning, it was just a little rumor in private, and no one believed it. But when someone really got a can of leftover caviar, everyone believed it.


    Even if the rationalists are willing to calm down and think, they have to follow the crowd rather than insist on the so-called truth.


    As a result, not a month after the two previous riots subsided, a new one was brewing.


    The leaders of the revolutionary army naturally noticed this. After all, Oleg, a KGB senior spy, is now working in the internal intelligence of the revolutionary army. In order to avoid causing more riots, he will report all kinds of intelligence to the Revolutionary Committee in time.


    Although a few young people in the committee are leaders because of the sweeping trend, they are not careerists. In the face of this situation, they also want to try to calm down the signs of the riots¡° We can''t allow rumors to spread. If it goes on like this, it will only lead to another riot. This time we have no chance of winning at all As the "opposition" within the committee, WA Lianjing is a rare rationalist. Of course, he can see that the reason why the revolutionary army was able to rise suddenly in the last riot and gain its present power largely depends on the support of the former oligarchic armed forces and the forces controlled by the rich. They are just puppets pushed to the front stage. Now that the oligarchs and the rich have been pulled out, the revolutionary army is like a toothless tiger, which poses no threat to the government. Although the source of internal rumors can not be found, what kind of consequences will be caused by allowing rumors to spread can be clearly foreseen. I''m afraid the government has long wanted to completely suppress the revolutionary army. In this case, another riot is just an excuse for the government to suppress it¡° What wa Lianjing said is right. We can''t set off another riot. In that case, it will only give the official an excuse to suppress us! " Dalia''s face was also very ugly at the moment. She thought about it seriously and said, "in this situation, it''s meaningless for us to continue to insist on the revolution. I propose that we formally surrender to the authorities." www.novelhall.com , the fastest update of the webnovel!

    "What? How could the revolutionary army voluntarily surrender? " When Chen Xin heard the news, he was full of surprise.


    This made him very puzzled and strange.


    In Chen Xin''s view, those so-called revolutionary forces are young people who are not very clear headed. They can not realize their mistakes so quickly, nor can they wake up so quickly in the face of difficulties.


    They will choose to fight stubbornly even if there are more difficulties. That is the route they will choose.


    But what is the way to surrender?


    "When I first heard it, I thought it was incredible." The staff who came to report to Chen Xin also had a face of disbelief: "the intelligence reported by Lucia said that the top level of the revolutionary army had realized that if they continued to fight against the government, it would only lead to more and more hardship for the people and was not conducive to the reconstruction of the country, so they chose to surrender."


    "Aware of the unfavourable situation, the situation has gone, so you choose to give up? It''s not impossible... "Chen Xin nodded understandably about the choice of the revolutionary army''s top management.


    He had met several people at the top of the revolutionary army before. Although they were all young people who were not very clear headed, there was no lack of idealists who hoped that the country would become better.


    But they are willing to surrender. Will the people in the middle and lower classes of the revolutionary army who are extremely dissatisfied with Lucia''s official position and the careerists who mingle in the revolutionary army be willing to surrender?


    Chen Xin was not sure, so he asked the staff about his doubts.


    "The high level of the revolutionary army took this into consideration, so they gathered the core members of the opposition that they had already controlled, controlled these opposition with their loyal armed forces, and then let Lucia''s official Army into the territory of the revolutionary army to suppress those who wanted to surrender." When the staff talked about this, the expression on their faces became a little complicated: "although there was a certain amount of confusion and conflict, they quickly controlled the situation. Although there are still sporadic resistance, the matter is basically under the control of Lucia''s official."


    "It''s quite surprising. These revolutionary army guys are very resourceful." Chen Xin was a little surprised, but he didn''t think it was too unexpected. After all, KGB has penetrated into the revolutionary army. In this way, the government can''t solve the problem


    Then Chen Xin had to let Titan go down to fight the riot.


    But now it seems that there is no need.


    Perhaps the only thing that surprised Chen Xin in the whole thing was the choice of those high-level revolutionary army officials, right?


    After all, not everyone is willing to give up their rights, just to make others live better.


    From this point of view, the top ranks of the revolutionary army have finally taken on the appearance of a real revolutionary.


    Having talked about this issue, Chen Xin brings the topic back to the weather controller.


    After all, no matter what happened to the lucians, it was only their own business. The weather controller was the only problem that Chen Xin and his Chinese people had to solve.


    "The upgrading of the weather controller has been completed, and the preparations for the third test are ready. Academician, when do you think the third test can start?" The staff asked Chen Xin for instructions.


    Because almost all the work of this upgrade was done by the staff, they put their efforts into it, and at the same time, they also made everyone have more expectations for the weather controller. Naturally, they also had more earnest expectations for the third test.


    Chen Xin was able to understand this emotion, and he didn''t hesitate about it. After thinking about it, he said, "now that we are ready, let''s start the experiment as soon as possible and choose a better time."


    "Do you want to choose an auspicious day?" When the staff heard Chen Xin say this, they couldn''t help joking.


    "Ha ha, it''s OK to choose a good day! Superstition is also for the sake of making a good fortune Chen Xin just laughs at this.


    Although it''s a bit superstitious to look at the old yellow calendar, it can bring people psychological comfort and protection. Chen Xin naturally won''t reject such things.


    After all, who can guarantee that these things are really groundless? If there are some forces that human beings can''t understand at present influencing all this, wouldn''t it be self troubling to resist and exclude?


    After all, no one knows whether the so-called superstition is a trace of high latitude civilization. However, after seeing that high latitude civilization is just an entertainment system, it has black technology that Bluestar technology can''t observe. Chen Xin still thinks it''s better to believe it and have peace of mind.


    "OK, I''ll find someone to calculate and see if there are any good days recently." Hearing Chen Xin say so, the staff are also happy, very seriously ready to find someone to count the day.


    However, the joke belongs to the joke, and the staff are still very serious about the various issues of the test with Chen Xinhe.


    Chen Xin is not careless either. Although he is not a professional, he has become very professional after taking over these jobs for such a long time. In addition, he has personally handled the whole weather controller project. He is familiar with every step of the experiment, and has never let go of any possible problems.


    After the two spent a long time checking the whole test process, Chen Xin thought of another thing, so he said to the staff: "we arrested two lucians in the last test. Although we didn''t mind others looking at the test, we still need to pay attention to some safety problems. Let''s arrange the guard and patrol in this test."¡° I know. Then I will contact the security and let them do a good job in this aspect. " When the staff heard Chen Xin mention this, they also looked awe inspiring and nodded seriously¡° Don''t be too nervous. It''s just a routine for them to set up guard and patrol. To tell you the truth, I don''t think it''s more than 100 degrees below zero. There are so many people idle and bored, just to see the weather control experiment that can''t be seen at all. " Chen Xin seems a little indifferent to this. After all, if you don''t enter the base, just looking outside, all you can see is that the mobile base fires, and then the wind blows in the test area. These superficial things can''t touch the core of the weather controller. Security guards and patrols are just for the sake of safety. I don''t want to see any more chaos. However, Chen Xin''s attitude is not very concerned, but the staff are still very serious. They don''t think the vigilance work can be perfunctory. On the contrary, they think that there was a problem last time, and there must be no problem this time. www.novelhall.com , the fastest update of the webnovel!

 Chapter 565

    "Is the patrol route clear this time?" In the bottom hangar of the mobile base, the commander spoke to the soldiers gathered in front of him before the mission: "last time I was sneaked into the test ground by two spies, I lost face in front of academician Chen!


    Our security work is not done well! It''s not just losing my face! It''s a shame on all of you! Academician Chen is kind-hearted. Because we were not asked to clear the site last time, no one was held responsible for this. But! But... "


    The commander said here, especially emphasized, and the expression of the soldiers who listened to him also became more dignified.


    Yanguo''s soldiers attach great importance to honor, whether it''s personal honor or collective honor. The last time they were touched into the test site by spies, even if Chen Xin didn''t tell them to clean up and patrol, it''s still a shame for everyone.


    Therefore, every soldier participating in this patrol mission can not help but hold a breath. They not only want to put an end to all problems, but also want to catch a few more spies. Fortunately, Chen Xin has proved that the soldiers of Yan state will never make a second mistake on the same issue.


    "Everyone should be ashamed! It''s a huge mistake in itself to let the spy touch the test area! " The commander was still yelling.


    When this happens, the most uncomfortable thing is actually the person in charge of security.


    If it''s not for the trouble of sending someone from China to replace the commander, and Chen Xin is saying good things for him, I''m afraid that the country will be held responsible and replaced to take charge of the security work.


    However, even so, more soldiers have been sent to China to provide better security.


    In this test, the commander also made great efforts. He not only made precise patrol route planning for the entire test area, scattered all the soldiers who could be deployed under his hands, but also used all the UAVs, helicopters and other equipment, so as to spread the sky and earth net and eliminate all hidden dangers.


    After a severe lecture, the commander finally got to the point: "so this mission, no mistakes or accidents are allowed! Do you have confidence? "


    "Yes!" All the soldiers cried out.


    "Good! What we want is this momentum! Let''s go The commander didn''t talk nonsense any more and ordered the operation to start with a loud drink.


    At the command of the commander, the soldiers boarded the all terrain vehicle and armored vehicle carried here respectively, and rushed out from the open exit, while the other soldiers went up to the hangar on the top floor, where they took the helicopter to the scheduled patrol location.


    The test area demarcated in this test is much larger than that in the last two times, because what Chen Xin is going to do this time is to really influence and manipulate the weather, rather than just test equipment before.


    Therefore, the designated test area has become much wider. Although the area with a radius of more than ten kilometers is much smaller than the area expected to be affected by the test, it is still a vast area.


    Fortunately, due to the impact of environmental factors, there is snow everywhere, there is no hidden shelter, and there is no animal interference, which reduces the difficulty of security and patrol work.


    The soldiers only need to set up dynamic sensors around the test area, set up radar, patrol according to the planned route with the help of all terrain vehicles and snow motorcycles, and cooperate with the air support of UAVs and helicopters. They can control this area, and prevent people from touching the test area like last time.


    This time, Chen Xin is still watching the test on the mobile base, but this time the mobile base is located in the test area, rather than firing shells from outside the test area into the test area.


    Moreover, this time, there was not one special shell fired, but a total of 16.


    Because it''s a test that really affects the weather, this time everything is operated according to the standard, unlike the previous test.


    Sixteen shells will completely cover the entire test area, and then catalyze under the influence of the microwave projected by the weather controller, and finally achieve the purpose of influencing the weather and forming rainfall.


    In addition, another reason why Chen Yu makes the mobile base stop in the test area is that he needs to test the impact of the microwave emitted by the weather controller on the human body and various mechanical equipment.


    After all, it''s a civilian equipment to affect the weather in the area. You can''t empty the people in the covered area before using it every time?


    Although according to the data from the previous two tests, the microwave projected by the weather controller is theoretically harmless to the human body, this upgrade was specially adjusted for this problem.


    However, it is uncertain whether the high-power radiation is really harmless to the human body and whether the mechanical equipment and electronic products in the area will be affected.


    So this time, Chen Xin will let the mobile base enter the test area for relevant tests.


    As for the security of the mobile base itself, there is no need to worry about it. When the prototype was made in the suvia era, it was designed for nuclear war, and its external defense performance is excellent.


    Chen Xin only optimized the structure, adjusted the power source and added new functions in the upgrading and transformation of the mobile base, and did not weaken the defensive performance of the mobile base itself. On the contrary, he strengthened it again according to the requirements of modern war. It can be said that the mobile base has enough defense to resist the possible danger. In fact, this is also a part of the test. The test is not only aimed at the weather controller, but also the military hopes to actually test the defense capability of the mobile base. In particular, this invisible microwave is an invisible killer in modern war. It''s better to defend against the visible attack with naked eyes and radar, but the invisible attack is the most difficult to resist. For this test, the military has made a lot of efforts to equip everyone on the mobile base participating in the test with special protective clothing, so as to avoid casualties. As for the damage of machinery and equipment, the military does not pay attention to it. If it is damaged, it is easy to repair it. As long as there is no problem with people, it is easy to say. It is for this reason that Chen Xin came to the mobile base in person. He also hopes to experience the actual impact of the weather controller and see if there will be problems in the mobile base. Because next, he will consider how to move the weather controller to the mobile base. If something goes wrong with the mobile base at this time, it will affect all his future plans. www.novelhall.com , the fastest update of the webnovel!

    Facts have proved that strict patrol and security measures are necessary.


    On the outskirts of the test site, the patrolling soldiers again found the lucians who wanted to touch the test area.


    However, their luck is obviously not as good as Oleg and his men. Before the experiment started, they were found by fully armed patrol soldiers and directly caught on the mobile base.


    "Send them to the base and give them to Lucia directly. The test will start soon. There is no time to interrogate them, and it is not suitable to leave them here." Chen Xin looks at the arrested Lucian and the commander who finally feels proud. He shakes his head and signals him to give the person to Lucia directly.


    The test will start soon, and the mobile base will be covered by the microwave radiation of weather controller.


    It doesn''t matter that they wear special protective clothing, but although these lucians are wrapped in thick clothes to resist the cold, they have no protective measures.


    It''s ok if it''s irradiated by microwave, but if it''s OK, it will be the same as putting raw eggs in the microwave oven, so it''s sure to send people away.


    Although Chen Xin wanted to test the effect of microwave irradiation on the weather controller, he was not crazy enough to do experiments with living people.


    As for interrogating them, Chen Xin doesn''t have the spare time to do so. He just comes to spy on them. What else can he do? Even if there is, we can ask Lucia''s official to interrogate him well without his own trouble.


    The commander took the order and gave the captured Lucian to the helicopter. After that, the soldiers continued to patrol closely.


    At the same time, the experiment has entered the countdown.


    "All ships ready! Prepare for shelling In the command room, although I have had an experience, the captain is still very nervous, and the whole person is serious to a tense state.


    This time, 16 shells will be fired continuously, and even supplementary fire will be carried out according to the situation, which is a new test for the members of the whole mobile base.


    They had also conducted artillery training before, and even launched shells in the last test, but they fired 16 times in a row, which is totally different from single shot.


    Continuous rapid firing and adjusting the firing position for each design is a great test for the artillery itself and the Gunners. After all, this is not an anti-aircraft gun used to fight aircraft, and it can''t shoot continuously like a machine gun.


    "Academician, the artillery is ready. It can be launched at any time. Please instruct!" As before, after the artillery preparation, the captain reported to Chen Xin.


    "Stand by." Chen Xin nodded, picked up the phone and contacted the base: "how is the weather controller ready?"


    "Report to academician, 90% of the weather controller charging has been completed, all preparations have been completed, start the test at any time!" It''s also good news from the base. After all, they have been tested twice. We are familiar with what to prepare.


    When Chen Xin heard such a report from the base, he nodded with satisfaction, so he said to the phone, "start the test!"


    After receiving Chen Xin''s instructions, the base and the mobile base immediately started to operate, while Chen Xin himself came to the observation window of the command room, where he could clearly see the turret on the deck.


    In the last test, because only one shot was fired, and the location of the shell was far away from the mobile base, Chen Xin did not see the shell firing. This time, he wanted to see the shell firing with his own eyes.


    Without Chen Xinjiu and others, the turret on the deck moved quickly, and then with the captain''s command, the 130mm caliber naval gun roared.


    The shell shot out from the muzzle like electric light and exploded in the sky, accompanied by a sound like thunder.


    Even though the observation window and the command room had been soundproofed, Chen Xin still felt the amazing movement of the 130mm caliber naval gun when he was standing by the window.


    Sixteen shots in a row. It''s like sixteen fireworks have been exploded from a distance. However, when you stand at a close distance and watch the shells being fired, what reverberates in your ears is sixteen thunders resounding through the sky.


    Looking at the 16 firelights in front of him and feeling the red mark left by the sudden light on his retina, Chen Xin looked up at the place where the shell exploded.


    Although it''s hard to see clearly, the flash of light still allows Chen Xin to see the smog like chemicals gradually spreading in the sky when the later fired shell explodes.


    This makes Chen Xin excited and looking forward to. He hopes that this experiment can be a complete success.


    "Academician, the base is about to start the machine for microwave irradiation. Please change into protective clothing as soon as possible." Chen Xin didn''t wear protective clothing. At this time, the captain, who had wrapped himself in heavy special protective clothing, urged Chen Xin, worried that he was going to verify the effect of microwave irradiation of weather controller.


    Hearing the captain''s advice, Chen Xin patted his wrist, and his original clothes turned into nano armor, wrapping his whole body up, even his face under the heavy armor.


    With nano armor, Chen Xin''s voice became a little dull, as if he was talking in an iron can. However, he still looked at the sky outside and asked the captain, "has the projection started?"¡° Not yet. " The captain took a look at the electronic clock in the command room and said to Chen Xin, "this time, we need to wait until the chemicals in the sky are completely dispersed and the diffusion range reaches the maximum before microwave projection starts, so it will take a few minutes." Chen Xin nodded and switched the visual mode of nano armor. In different visual modes, he can clearly see the situation in the sky and the change of surrounding temperature through the display interface of armor¡° I hope this experiment will be a complete success. " Chen Xin murmured to himself, feeling nervous. In this experiment, what they want is not just warming up and windy as before, but to change the weather to make the test area rain. To achieve this goal, it is much more difficult than the previous two experiments. Even Chen Xin can only hope that the experiment is successful. After all, the upgrade of weather controller this time does not rely on the system black technology, but on the efforts of the staff. Even Chen Xin doesn''t know whether this experiment will succeed or not. This kind of expectation and tension, which he had never had before, made Chen Xin have a new experience. After taking a deep breath, Chen Xin silently estimated the time. A few minutes passed quickly, and the microwave projected by the weather controller immediately shrouded the entire test area. www.novelhall.com , the fastest update of the webnovel!

 Chapter 567

    In the infrared vision mode of nano armor, Chen Xin clearly saw that as the microwave of weather controller projected to the designated area, the color of the sky gradually changed from black purple to blue.


    In infrared vision mode, the lower the temperature, the more the color will go to the purple end of the spectrum, while the higher the temperature, the more it will go to the red end.


    Now the sky in Chen Xin''s view has changed from purple to blue, which is enough to show that the temperature has obviously increased, and the increase is still continuing.


    With the further microwave irradiation, the sky is close to cyan, even turning green.


    The display screen of the nano armor also shows that the temperature at this time is - 14 ¡æ, and it is only a little bit close to breaking through zero.


    In fact, it''s not only Chen Xin who has seen the temperature rise. At this time, the mobile base has turned on all the observation equipment, and also has monitored the temperature rise in the sky in real time.


    The air expansion and flow caused by the rapid rise of temperature in a short time caused strong wind again in the test area.


    Standing in front of the observation window, Chen Xin can even feel the whistling of the strong wind. A vertical antenna on the deck is even blown to produce an amazing radian.


    But this has not affected Chen Xin''s mood at the moment, because he is expecting the temperature to rise a little higher and the wind to be stronger. Even if the antenna is blown off, it is acceptable.


    Because it means that the temperature in the sky has risen to the temperature Chen Xin needs.


    "Keep going! Break through zero quickly Chen Xin looked at the change of color in the sky and couldn''t help muttering.


    Although the current situation looks very good and the experiment seems to be going well, Chen Xin''s tension has not slowed down for half a minute.


    If the temperature can''t rise above zero and the rainfall can''t form, then the experiment will not be a success. No matter how strong the current momentum is, it doesn''t make any sense.


    In Chen Xin''s expectation, the temperature in the sky continues to rise, but it seems that the rising speed has entered a bottleneck, and gradually slows down as the temperature approaches zero.


    This situation is expected by Chen Xin, and the same situation has happened in previous experiments. However, Chen Xin is still worried and nervous for fear that this experiment will fail.


    Fortunately, it seems that the situation is not developing in a bad direction. Although the speed of temperature rise has slowed down, it is still rising steadily, and finally broke through to 1 ¡æ under the gaze of Chen Xin.


    Seeing that the temperature broke through to 1 ¡æ, Chen Xin got excited and couldn''t help cheering.


    At the same time, other people in the command room also cheered for this moment!


    Although the rain has not yet formed and the biggest goal of the experiment has not been achieved, the temperature has risen above zero, which is a new breakthrough.


    You know, in such a long time after the impact of meteorites, except for special circumstances, the global temperature has not risen above zero for a long time.


    At this moment, it is not easy to let the temperature rise to above zero again with the help of human beings, and it is also a matter worthy of celebration.


    And the most important point is that only when the temperature is above zero can rainfall form.


    But the formation of rainfall in addition to temperature, there are many other factors, this time whether the real formation of rainfall, whether Chen Xin or the staff are not sure.


    Although according to their calculation data, rainfall can be formed, no one can guarantee that the derived results will be realized.


    What if there is a little deviation, or the environmental conditions can not meet the requirements of rainfall, there is no rain?


    No one can put an end to such a situation, and no one can guarantee that it will not happen.


    So despite the cheers, everyone soon got back into the intense work, even though their work was only to monitor environmental changes and could no longer have any significant impact on the whole test process.


    Just when Chen Xin couldn''t help but want to increase the radiation power of the weather controller on the other side of the base, an instrument in the control room suddenly flashed and sparked.


    "Well? What''s going on! " Chen Xin turned his head and looked at the device that had sparked: "cut off the power quickly! Stop the fire


    The operators of the equipment were also startled, but fortunately, the operators on the mobile base were all soldiers. At the moment, they were able to deal with the problem calmly. They immediately cut off the power supply of the equipment and prevented the equipment from producing electric sparks and developing into a fire.


    Seeing this scene, Chen Xin knew that it was impossible to continue to increase the power of microwave irradiation.


    So he said to the captain, "inform the base. According to the original plan, let the weather controller end the irradiation."


    Although the rain has not yet formed, the microwave irradiation time has reached the predetermined time of the previous experiment. Since there may be problems if the microwave irradiation continues, it is better to stop according to the original plan.


    The captain didn''t say anything more. He just nodded his head. On the one hand, he arranged for people to check the mobile base to see if there were other places where electric sparks and fire might occur. On the other hand, he also connected with the base and conveyed Chen Xin''s instructions.


    The base received Chen Xin''s instructions. Although they were still not willing to end the experiment, they also knew that scientific experiment was nothing else, and recklessness could not solve the problem. At this time, the best way is to carry out according to the original plan. After the test, we can find out the problems and summarize the experience and lessons, and analyze why there is no rainfall. So despite the reluctance, the weather controller stopped as planned. After the weather controller stopped, the temperature had reached 7 ¡æ, which was not a low temperature. If we can continue the microwave irradiation, maybe the temperature can be further improved, but after the weather controller stopped, the temperature began to fall rapidly. Chen Xin''s face showed a look of regret. He had great expectations for this experiment, but he did not expect that this experiment could not produce rainfall¡° What''s wrong? Obviously, according to the calculation, rainfall can be formed! We also specially measured the air humidity to judge whether there are conditions that can form rainfall Chen Xin stood beside the observation window with a dignified expression on his face. However, just as he was thinking about what went wrong, the bent antenna on one side had been re erected and began to fall in the opposite direction. At the same time, there are also very small snowflakes in the sky slowly falling on the observation window. Seeing this scene, Chen Xin suddenly widened his eyes. The hexagonal structure of snowflake is so beautiful at the moment. www.novelhall.com , the fastest update of the webnovel!

 Chapter 568

    The snow fell. This time, it was not the snow blown by the strong wind, but the real snowflakes falling from the sky.


    "It''s really snowing!" Chen Xin rushed out of the command room and came to the deck outside.


    Looking up at the sky, snowflakes are falling, although the sparse, it looks like only a light snow, but it seems to be a hope.


    "It really snowed!" At this time, the operator of the mobile base and the captain also came to the deck, looking at the snowflakes gradually falling from the sky, also made an exclamatory sound.


    I''m afraid this is the first time you''ve seen natural snowfall since the impact of meteorite and the global temperature dropped below zero.


    This can not help but make everyone excited and sigh, because this snow is produced by the influence of science and technology, and it is also the goal of these people''s efforts and struggle.


    Now that the goal is achieved, how can we not be excited?


    "Academician, it''s snowing!" A staff member beside Chen Xin is shouting excitedly to him, and there are more staff members who are also shouting beside him.


    Looking at the cheering staff, Chen Xin''s face was also full of smiles. He was as excited and excited as they were.


    Chen Xin feels the same excitement and excitement of these staff members. This time, he and these staff members devoted too much effort to the experiment. They thought that the experiment was unsuccessful, and they were all ready to fail. But now the success has really affected the weather. How can we not feel the joy of success?


    Although the strong wind is sweeping at the moment, with the weather controller turned off, the temperature is constantly falling, and the cold wind is blowing so hard that everyone''s clothes are noisy, but at this moment, the noise of the wind can not cover up everyone''s joy.


    It can improve the local weather, although it is only a light snow, and even the small snow will soon stop, but it still marks the success of the research on weather controller. They can control the weather and try to improve the current environment.


    Even though it''s only a small attempt, it''s a good start. No matter Chen Xin or many of the staff involved in the experiment, we all believe that from this moment on, they can gradually modify the environment of Bluestar. One day, this research will change everything and restore the environment of Bluestar to what it was before the disaster.


    Everyone cheered and celebrated for a long time, and it didn''t return to the mobile base until the snow stopped.


    After cheering the victory, we still need to work hard.


    A staff member sent a report to Chen Xin: "academician, in the previous test process, the microwave radiation of weather controller had a certain impact on the electrical circuits in the mobile base. This is the statistical result of loss. Please have a look."


    Chen Xin took over the report and read it carefully. At the same time, he asked the staff, "apart from the damage of the electrical circuit, are there any other losses? Do the operators on board have any physical discomfort or other conditions? "


    "There are two individual crew members who are suffering from physical discomfort, manifested as mild vomiting, dizziness and other symptoms. At present, they are being treated in the medical room, and the situation is not serious." The staff reported to Chen Xin and explained: "they mainly stayed in the kitchen during the experiment. Many metal kitchenware in the kitchen were affected by microwave irradiation, which had an indirect impact on them. In addition, everything was normal."


    "We still can''t be careless, and then let them go to the base to receive a comprehensive examination, to ensure that there is no mistake, and we can''t make fun of the comrades'' bodies." Chen Xin attached great importance to this, and did not really feel that there was no problem because the staff said there was no problem.


    When the staff heard Chen Xin say so, they also wrote down his words seriously: "I know the academicians, and then they will be arranged to go to the base for a comprehensive physical examination."


    Seeing that the staff had written down what they said, Chen Xin continued to ask while turning over the report: "there has been a certain degree of short circuit and meltdown in the electrical circuit. It seems that microwave irradiation still has a great impact


    I saw an electric spark generated by equipment in the command room before. It didn''t write on it. Didn''t it cause any damage? "


    "Yes, because the power was cut off in time, the device itself did not break down, and it can still be used normally after restarting." The staff explained to Chen Xin.


    Chen Xin nodded clearly, put down the report and fell into thinking.


    Of course, the mobile base itself has defensive measures, and it has enough resistance to microwave radiation and EMP impact that may appear on the battlefield.


    However, there is an upper limit to this defense capability. The microwave irradiation for such a long time in this experiment has broken through the defense of the mobile base, which will cause damage.


    However, this is not the main reason for Chen Xin''s thinking, because according to the initial prediction, the microwave radiation generated by the weather controller should not have such a great impact on the mobile base, let alone cause any damage to the human body.


    However, the result of the report now is that the metal kitchenware in the kitchen was indirectly affected by microwave irradiation, and at the same time, it also caused damage to the electrical circuit of the mobile base, which had to make Chen Xin think about the causes and problems.


    The problems in the kitchen can be ignored for the time being, but the electrical circuit of the mobile base has special protection. In this case, it still causes a lot of damage. It is very necessary to investigate the causes and solve the problems, so as to prevent similar situations in the future. As for the cause of this problem, Chen Xin is not very good at electrical, but he thinks it should not be caused by inadequate protection. But Chen Xin himself can''t figure out the reason for it for a while and a half. He can only roughly speculate that it may be caused by the high microwave irradiation power generated by the weather controller. The more specific reasons can only be analyzed by professionals¡° The damaged parts of the mobile base in this test should be repaired in time, without delay. If any problems are reported in time, the base will solve them. " Chen Xinru told the staff. The mobile base is related to Chen Xin''s next stage of upgrading the weather controller. He does not want any mistakes or mistakes in the mobile base. If it''s not that this is just a small damage, the maintenance personnel of the mobile base can fix it by themselves. Chen Xin even wants to use the system upgrade to repair the mobile base. Even so, the mobile base will be upgraded later. After all, what Chen Xin will do next is to move the weather controller that can affect the weather to the mobile base. www.novelhall.com , the fastest update of the webnovel!

    The success of the experiment allowed Chen Xin to relax for a while.


    Although there is still a lot of work to do, it''s OK to give yourself a half day off to have a good rest.


    It''s just that he''s living in Lucia now, and he''s still living in a base in the era of suvia. Even if he''s upgraded before, some things inside are still full of Suzhou flavor. It''s not very comfortable to live in, and there is a lack of entertainment facilities.


    Of course, for Chen Xin, although he took half a day off, it doesn''t mean he can really play.


    In his spare time, Chen Xinhui plays games, chats with Mo Qingyan and Qin LAN, or accompanies his parents.


    But in places like Lucia''s former suvia base, Chen Xin''s rare spare time in the afternoon is to go to the greenhouse.


    This greenhouse is reconstructed from the original warehouse of the base, using the latest modular ecological shelter planting technology of Yanguo. After the greenhouse shelter assembled from China arrives here, it is directly assembled for use, instead of transforming the warehouse into a greenhouse.


    This technology is not within the scope of Yan''s assistance to Lucia. Although it is not a big deal to export a few shelter, Yan''s technical support to Lucia is still to help them transform the permanent greenhouse, rather than the shelter greenhouse that can be removed at any time.


    This is not a decision made by Chen Xin, but a decision made by the domestic side. Chen Xin is too lazy to go into the cause. Anyway, he knows what he has.


    The area of a single shelter greenhouse is not large, which is about the size of a traditional container, but after several containers are put together, the shelter greenhouse is not small at all.


    There are a large number of fresh vegetables, fruits and staple food crops, which are rich in variety. Although the yield is not enough, if we just maintain the consumption of these people in the base, there is no problem.


    The reason why Chen Xin came here is that he wanted to make some fresh vegetables and fruits and cook his own food.


    For Chen Xin, spending time on cooking is always the best way to relax.


    Container type shelter greenhouse each container is a separate individual, they can exist independently, under the long-term power support provided by isotope battery, the greenhouse built by ecological technology can operate for a long time, in addition to the necessary care, it does not need to bother to maintain.


    This was originally the shelter planting technology used by the army, and it was developed to provide vegetables and fruits for border posts with poor transportation and poor environment, such as plateau and snow mountain.


    With the support of various kinds of black technology obtained by Chen Xin through the system, this technology has also been upgraded, and now it has become a container greenhouse with more convenient maintenance, higher output and more varieties than before.


    Although each greenhouse is a separate individual, several containers are considered to be used together at the beginning of the design, so the connection channel of each container greenhouse is designed in advance.


    Even the inside of the container is equipped with stairs, which can stack the two containers and save the floor space.


    For this kind of container greenhouse, Chen Xin likes it very much. If he could have such technology before the disaster, when he built his own refuge, he would have made one for himself.


    In fact, this technology has been vigorously promoted in China.


    Some of the existing shelters are not convenient to use, but many of the shelters reconstructed after the earthquake in Southwest China use this technology.


    This container type greenhouse has a solid structure and a special anti-seismic design, which can resist earthquakes of magnitude 7 or above. Besides providing vegetables, fruits and food for the shelter, it can also be used as a safe space to avoid earthquakes.


    In fact, a large part of the reason for adopting such a design is due to the problems reflected by the previous earthquake in Southwest China.


    The shelter itself should be used to resist disasters and provide emergency shelter for the people when disasters come. However, the earthquake has made the shelter which originally provided the function of refuge dangerous, which is undoubtedly very difficult to accept.


    Therefore, in the process of reconstruction, in addition to strengthening the seismic capacity of each refuge, the strengthened and stable safety points of this structure are specially designed for emergency refuge in the refuge in case of disaster.


    The reason why we choose to plant greenhouse is mainly considering the problem of food supply.


    After all, as we all know, being buried under the ruins is not the most terrible. As long as there is a certain space, without the whole person being pressed down, we can support ourselves with food and water until the rescue comes.


    So a greenhouse that can provide food and water when necessary is a good choice.


    In particular, the container greenhouse has a separate power supply system, and the plants inside can provide the necessary oxygen for photosynthesis.


    Of course, despite the benefits, no one really hopes to use these functions one day. The biggest function of these container greenhouses is still to produce crops. Chen Xin goes through a container greenhouse, goes to the bottom, climbs the stairs connecting the upper container, and looks at the colorful fruits and vegetables in the container greenhouse. His happiness is spontaneous. Here, we can basically find most of the common vegetables and fruits before the disaster, and a small part of them are easy to grow and harvest. For the present eschatological environment, the sense of security and happiness brought by having such a container greenhouse is incomparable to having a whole manor before the disaster. Satiety is always the most urgent need of human beings, and eating well is always the first pursuit. Chen Xin reached out to pick some vegetables and fruits and put them in a basket. Although there was no meat, these vegetables and fruits were enough for him to make a good meal. After picking enough food, Chen Xin suddenly thought of the caviar he had seen at the banquet held by lucians when he was carrying these vegetables and fruits back. In fact, in a sense, these fruits and vegetables are more luxurious than caviar. After all, it''s hard to say who is more luxurious between maintaining the survival of several fish and maintaining a greenhouse that can continuously produce fruits and vegetables. Chen Xin touched his nose, put these meaningless ideas behind him, reached out and picked up a fresh tomato from the basket, and ate it raw. The sweet and sour juice permeates into the mouth, which brings us peace of mind. www.novelhall.com , the fastest update of the webnovel!

 Chapter 570

    A basket of fresh vegetables and fruits is made into a rich dish by Chen Xin. Although there is no meat, in the present environment, fresh vegetables can satisfy people.


    With a few tins and a little wine, even before the disaster, it can be called a feast.


    However, considering that he still has to work tomorrow, Chen Xin didn''t make wine for himself. After all, he was in Lucia. The wine he got was basically high vodka, while the wine with low alcohol was only a bottle of Georgia red wine he planned to bring back to Mo Qingyan.


    It was something that leader Lucia gave him with historical collection value. It was a bit wasteful to drink it directly.


    However, even if there was no wine, it was also a big dinner. Chen Xin obviously had too much to enjoy alone, so he invited several other people from the base to celebrate the success of the experiment.


    "Wow! What a feast! Academician Chen, you really have no skill The first to arrive was the captain of the two ark. As soon as he entered the door, the captain of the Xu dog showed a look of praise.


    The captain of the Haizhu ship offered a gift to Chen Xin, a box of canned fruits.


    Compared with fresh fruit, canned fruit is more durable to store. This kind of thing, which was not popular in the market, has become the only way for ordinary people to eat fruit. Even the two ark captains who come to Chen Xin''s place as guests, also use this kind of fruit can head as a gift.


    Chen Xin doesn''t care much about this. In his capacity, he can get any fresh fruit or canned fruit he wants.


    Compared with the gifts brought by the two captains, Chen Xin was more happy that they could celebrate the success of the experiment together.


    In addition to the two captains, Chen also invited the captain of the mobile base, the commander of the security forces and the deputy of the test team.


    Originally, Chen Xin also invited two leaders of the rescue team and the expert team, but the two leaders were busy treating patients and had no time to come over, so there were only five people to enjoy this rich dinner.


    "Academician, I''d like to propose a toast to you. Without your leadership, this research will be successful only in a short time. You should be the first to succeed in this experiment! " The deputy of the experimental team raised the cup, replaced the wine with brown sugar water, and looked at Chen Xinjing.


    Chen Xin also held up the same cup of brown sugar water, touched it with the other party, and then said with a smile: "the greatest contribution to the success of this research is that everyone involved in it has been fighting together in Lucia, a land far away from the motherland, for less than half a year to make the machine work. Everyone has paid a lot of hard work and efforts for this matter, Everyone should be a hero. "


    Chen Xin said that although it sounds like a scene, he thinks so from the bottom of his heart.


    Although the system upgrade is the key factor to make the weather controller work and really affect the weather, without the hard work and dedication of all the staff, Chen Xinyi alone, even if he can upgrade the weather controller, can not operate such a large machine by one person.


    The success of this experiment is the result of the cooperation of all people, not just the contribution of one person.


    "Yes, it''s thanks to our joint efforts." Several people sitting at the table did not feel that the success of this experiment should be attributed to any one. Although the deputy said that Chen Xin should be the first to make contributions, it only said that Chen Xin made great contributions, not to deny the contributions of others.


    So after a few words of chatting, the captain of Xugou suggested, "well, we''ve been in Lucia for almost half a year. In a few days, it should be mid autumn festival. Why don''t we have a good celebration? It''s a celebration for all of us. "


    "That''s a good proposal. It''s almost Mid Autumn Festival. It''s time to celebrate." The proposal immediately won everyone''s approval.


    Although we don''t have the concept of holidays at the end of the world, the more it is, the more we need to celebrate traditional festivals and other activities to let us remember the past, instead of living more and more numbly.


    That will only let people gradually forget the past, forget the brilliance and glory of human civilization, leaving only the numbness of struggling to survive in the cold and darkness.


    If we don''t remember these traditional customs, they will be easily forgotten.


    So it is necessary to celebrate the Mid Autumn Festival.


    On the one hand, it can make everyone who has been in Lucia for nearly half a year feel homesick, on the other hand, it can also celebrate traditional festivals, so that even in this eschatological environment, people can recall the past traditions and customs far away from home.


    Of course, the more important point is to give you a reason to celebrate the success of the weather controller test.


    A few people can be regarded as the main leaders of the base, and after some sum up, this matter is even settled.


    However, in addition, Chen Xin suddenly thought of something and said to others, "everyone has been away from the motherland for half a year. They can neither call home nor go back for such a long time. Are they all homesick? Does anyone want to go back and see the family? "


    Speaking of this topic, everyone''s expression suddenly became a little heavy.


    Although all of you came voluntarily at the beginning, the time of staying in Lucia for more than half a year was beyond everyone''s original expectation.


    Although before the disaster, we all had the experience of not being able to meet our family for half a year, or even for a longer period of time, people can call before the disaster, and they can still write letters if they are in trouble. With such a way of communication, it is not enough to say that there is no sound at all.


    But now in this environment, even if you want to contact your family in China, you can''t find the right channels and methods.


    So when Chen Xin talked about whether anyone wanted to go home to have a look, everyone thought of his family for the first time.


    Just as leaders, they need to set an example. Even if the discussion really allows people to ask for leave to visit their families, they will not be the first group.


    "I agree to let everyone go back to visit their families, but I''d better take turns and come in batches. I''m afraid too many people will delay my work at one time." The deputy took the lead in talking, and he should have been responsible for this kind of administrative work.


    Chen Xin nodded in agreement, thought about it and said, "come according to the time when you come to Lucia. Those who have come to Lucia for more than four months can apply to return home and visit their families for a week.


    I will get in touch with the mainland, coordinate the transportation, and strive to let everyone go back to visit their families. "

 Chapter 571

    News of being able to ask for leave to return home to visit their families spread wildly in the base, and all of a sudden everyone''s mood was affected.


    Although we all came to Lucia with full consciousness, although the work was heavy and the environment was bad in the past six months, it was not very hard on the whole. It was not too much to insist on for a few months.


    But everything is afraid to start. After knowing that the superior is discussing allowing everyone to go back to visit their relatives, everyone can''t help but be aroused.


    They are now in Lucia, which is far away from their motherland. There are at least several thousand kilometers of roads in China. The long distance physically separates us from our country.


    Although the communication is not interrupted, it is obvious that the channels that can maintain communication with China are official channels, which are not suitable and unlikely to be used to call ordinary staff members and their families.


    Of course, this is not to say that ordinary staff can''t use these communication devices to make phone calls in China, but most of the communication devices in official channels only connect to various departments in China, not to shelters or individuals.


    Therefore, even if the communication equipment is open to ordinary staff, they can call various departments in China at most, and can not contact their families.


    As for writing a letter, it''s also a way. Before the disaster, there was no express that we used to use, but the national post was still in operation.


    It''s just that all the postal codes and regional addresses before have been in a mess due to this apocalyptic disaster. In addition to the damage of a large number of primary postal facilities and the collapse of the postal system, many of the addresses have been completely abandoned, and there are no postmen.


    Even if a letter can be sent back to China, it is not easy to find the corresponding address and send it to the recipient.


    Not to mention receiving replies from home.


    In this case, we have not contacted our family for a long time. I don''t know how the family is doing and whether everything is OK.


    In the past, I could use my work to paralyze and persuade myself, so that I could not think about these things as much as possible. But now when the higher authorities say that they can let everyone go back to visit their relatives, everyone can''t sit still.


    Some people went directly to their superiors and asked about going back to visit their relatives. Even if they were a little more reserved, they were asking around and secretly estimated whether they would have a chance to go back to visit their relatives.


    This kind of mood undoubtedly affects everyone''s work.


    Although everyone works hard and doesn''t delay their work because they are homesick, they are still thinking, which affects their morale and makes their work efficiency decline.


    Originally, we were asked to go back to visit our relatives in order to ease our thoughts and emotions and improve our work efficiency as much as possible. All of a sudden, it became what it is now, which really made Chen Xin and others unwilling to see.


    But at the same time, they also realized how serious people''s emotions are.


    After all, the missing for family accumulated in a few months is no more than before the disaster, which is enough to affect everyone''s working state.


    With this in mind, Chen Xin convened a formal meeting of other people to discuss and formulate a provisional regulation.


    According to the regulations, the staff who have been in Lucia for more than four months can apply to a temporary coordination group and score according to a temporary evaluation standard, so as to return to visit relatives in batches in the form of rotation according to the order.


    As soon as the regulations were published, there was a strong response.


    Of course, the most controversial issue is the evaluation criteria. After all, it involves whether you can become the first group of people to return to China to visit relatives. We are very concerned about this.


    But fortunately, the formulation of the evaluation criteria has undergone rigorous discussion, and it is not the result of a slap in the head decision. Generally speaking, there is no objection. What we care about is just how many points we can score and how many batches we can rank in.


    Because it''s a rotation system, only when one batch of people return home after visiting relatives, can the second batch return home. If the batch is later, it will undoubtedly stay in Lucia for a longer time than others.


    Fortunately, after the promulgation of the regulations, everyone''s mood has stabilized a lot. In order to return to visit relatives as soon as possible, some people''s work efficiency has also improved a lot, and even some people take the initiative to work overtime during their break time, so that they can finish their work as soon as possible and accumulate more scores.


    In the face of this situation, Chen Xin and others are relieved. They are afraid that the regulations will arouse everyone''s antipathy. In that case, the problem will be serious.


    Now that we can all accept it and implement it in accordance with the regulations, it is undoubtedly the most ideal result.


    However, this also makes Chen Xin and others feel that they need to arrange for everyone to return home as soon as possible. After all, even if it''s a donkey who has been hanging carrots but can never eat them, it''s not OK.


    So Chen Xin contacted the mainland, and after a new batch of materials arrived, he arranged for the first batch of returnees to board the return flight.


    In fact, it doesn''t take much. When these planes returned home, they were empty most of the time. Now taking some people back is also an effective use of resources.


    The only thing that needs to be coordinated is that after these people return home, the transportation problem for them to go home is arranged in China.


    After Chen Xin contacted China, the domestic side also provided a quite positive response, saying that it would coordinate all this well.


    Knowing this, Chen Xin was relieved to leave everything to the person who was in charge of these things.


    But after seeing off the first group of people who came back to visit their relatives, the Deputy asked Chen Xin a question: "academician, have you been away from home for a long time? From the southwest earthquake to now, you have been back home for two times, so long, don''t you miss home? Why don''t you go home to visit your family? "


    This is also a question that the deputy is very puzzled. Although Chen Xin, as the person in charge of the project, can''t be the first group to return home to visit relatives in order to set an example, his name can be written on the list of the next few groups.


    In terms of Chen Xin''s prestige and identity, as well as his contribution, this will not lead to any gossip, on the contrary, it will make people feel that he deserves it.


    But from the beginning, Chen Xin crossed out his name from the list of visiting relatives back home.


    "Yes! But compared with other people, I at least know that there is no problem at home, and I want to get in touch with my family, so it is not particularly urgent for me to go home to visit my family. " For this issue, Chen Xin''s performance is very indifferent: "and in my capacity, it''s just a matter of words to want to return home, there''s no need to rob everyone''s quota."

 Chapter 572

    With the welfare of returning home to visit relatives as a temptation and encouragement, all the people in the base quickly adjusted after their morale was shaken and regained their vigor and morale.


    The work is still carried out step by step.


    The situation of the third test is much better than that of the previous two. At least there is no problem with the equipment this time, and there is no need for structural adjustment and maintenance of the weather controller itself. Some of them just carry out further technical optimization and improvement on the basis of the existing test results, so as to make the machine work better.


    In addition, Chen Xin has been planning to reduce the size of the weather controller, move it to the mobile base, and turn it into a mobile medium-term goal.


    But it is not easy to achieve this goal in a short time, so relatively speaking, the atmosphere in the base is not as urgent and tense as before. Although all the staff are still working efficiently, they feel more leisurely.


    In this regard, Chen Xin is happy to see its success. Although it is said that upgrading the weather controller to a size that can be installed on the mobile base can be done instantly through the system upgrade, for the sake of safety, Chen Xin still decided to work with the staff to study and analyze the weather controller, formulate an upgrade plan, and then upgrade it.


    And it is also conducive to the accumulation of technology and training team experience, and improve the level of the whole research team.


    "Academician, according to our analysis, it is very difficult to install the weather controller on the mobile base according to the structure of the existing mobile base, so we must carry out a large-scale transformation of the mobile base." In the conference room, a staff member was holding a sketch and telling Chen Xin their conclusion.


    For this conclusion, Chen Xin did not express any opinions, but picked up the drawing and read it carefully before saying: "tell me your opinions, how do you want to change?"


    The current mobile base is mainly to carry personnel and provide regional support, so the structural design is mainly to accommodate personnel, so there is really no place to plug the weather controller into the whole mobile base.


    Even if it''s just the core part of the parts, it''s also necessary to dismantle the public space of the top hangar and personnel cabin, or even the garage on the bottom floor.


    Therefore, Chen Xin understands the staff''s proposal to modify the structure of the mobile base, and he actually has the same idea.


    Now I ask the staff for their opinions. To a large extent, I want to use them as a reference to see if there are designs or ideas that can make people shine.


    "We plan to replace the energy system of the mobile base first." The staff really have a lot of ideas. As soon as they come up, they intend to replace the power source of the mobile base.


    "Change it? What are you going to replace it with? " Chen Xin did not ask why, because the weather controller itself is a big energy consumer. If you want to install it on the mobile base, you must solve the energy problem.


    The original energy supply of the mobile base itself is no problem, but to add a weather controller, this is not the load that the energy of the mobile base itself can afford.


    Naturally, it is for this reason that the staff want to replace the energy system of the mobile base.


    So he told Chen Xin: "the plan is to replace it with a small fusion reactor. At present, there are mature technologies in China, so this scheme should be adopted. If it doesn''t work, it''s not impossible to use the isotope generator, but the output power of the isotope generator will be relatively low, and it may need to add two groups, so the structural layout needs to be adjusted."


    "Well, small fusion reactor... Yes, that''s a good idea. I''ll apply to China. You can improve the scheme in this respect." Chen Xin nodded, expressed his affirmation and support, and then continued to ask, "do you have any other ideas?"


    "Also, we hope to adjust the structure of the mobile base to make room for installing weather controllers on the mobile base." Although the staff said this, but the expression on his face was a little embarrassed: "but now the volume of the weather controller is undoubtedly much larger than that of the mobile base. Before the exact completion of the transformation of the weather controller, this idea is not very good to practice. We can only confirm how much space can be made on the mobile base."


    This is also a kind of helplessness for ordinary researchers. They don''t know how much the weather controller will shrink when they move to the mobile base. Therefore, they can only aim at the space that can be vacated on the mobile base, and try their best to reduce the weather controller to the range that this space can accommodate.


    It is not possible to adjust the size of the mobile base according to the size of the weather controller, because in that case, what needs to be redone is the whole mobile base.


    But for Chen Xin, it''s much easier to say, because he can adjust the mobile base according to the weather controller, and he can also adjust the weather controller according to the mobile base. No one has to adapt to who''s saying between the two, so they can adjust each other to achieve the most appropriate state.


    Therefore, Chen Xin didn''t explain much about the questions raised by the staff, but said to him, "don''t worry about this. Try your best to do it first. As for how to reduce the size of the weather controller and how to adjust the space of the mobile base, I will coordinate these things."


    "Good academician, I see." The staff nodded to understand what they should do.


    Chen Xin saw that the other party did not put forward any new suggestions, so he signaled to him to go ahead: "sort out the ideas. These two suggestions are very good. Let''s make a plan first. Don''t write the details in too much detail, and explain the ideas clearly."


    With that, Chen Xin picked up the previous sketch and handed it to the staff


    "I see. I''ll do it first." The staff took the sketch from Chen Xin and then turned to leave.


    After the staff left, Chen Xin himself used the nano molecules in his watch to simulate the structure of the mobile base in front of his eyes, trying to replace its energy system, and hollowed out its interior, trying to put a weather controller in it.


    But the weather controller itself is now many times larger than the mobile base, there is no way to put it into the mobile base.


    Chen Xin didn''t get stuck because the weather controller was too big. He tried to disassemble different parts of the weather controller and put them on different floors of the mobile base according to their functions.


    Trying and Thinking: "do you want to take the weather controller apart..."


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 573

    It''s really a way to reduce the footprint of the weather controller by disassembling it into different functional modules.


    Because when the suvians built the weather controller, they used the tile structure, which led to the fact that all the supporting facilities of the weather controller were on the same plane, resulting in a very large area of the weather controller.


    However, if it is divided into different functional modules, as long as the different functional modules are stacked, it can reduce its floor area.


    It''s like a big pool of more than a dozen books, but if you stack all the books together, it only takes up the area of one book.


    But even so, the current weather controller is still a huge beyond imagination.


    Most of the bases covering an area of more than a few hectares are the supporting facilities and functional modules of the weather controller. Even if Chen Xin can dismantle them and put them into the mobile base by categories, it is not what a mobile base can do at present.


    Even if the entire interior of the mobile base is hollowed out, the volume is too much.


    Therefore, before considering how to insert the weather controller into the mobile base, it is necessary to reduce the volume of various supporting facilities and functional modules of the weather controller.


    And this is a real hard battle, whether it is for Chen Xin or for the ordinary staff, it is a hard battle that needs real teeth.


    For the manufacturing industry, it is generally accepted that under the premise of ensuring the same function, the smaller a thing is, the higher the technical requirements will be.


    This is not only the problem of machining accuracy, but also an important factor is how to ensure the function of the equipment or parts in the case of reducing the volume, so that it can maintain the original function, rather than function attenuation due to reducing the volume.


    Take a simple example. The most important reason why a laptop is more expensive than a desktop is that its internal parts need to be smaller than a desktop.


    At the same time, we have to consider a lot of problems, such as power consumption and heat dissipation. It''s not just a matter of scaling down.


    This is not only the problem that laptops and desktops need to face, but also the problem that super large devices such as weather controllers need to face.


    Even more serious problems need to be faced by the weather controller.


    First of all, the problem facing Chen Xin and the researchers is how to solve the problem of power supply lines.


    Weather controller is a super energy consumer. It not only needs a nuclear power plant to power it, but also needs thick cables to transmit the surging power.


    If it''s placed in the base, it''s OK. It''s a big deal to dig a cable trench for the thick cables. There''s always a place to arrange them.


    But mobile base is not the same, its volume is only so large, how to wire can be said to be a science.


    Because this is not only to connect the lines, but also to ensure that the lines will not interfere with each other. The energy transmission efficiency of the lines must be in the best state. At the same time, the more critical point is to be able to plug so many cables into the limited space in the mobile base.


    "I have contacted with China, and the small fusion reactor will be delivered to China as soon as possible. Before that, we need to come up with a basic scheme for wiring." Chen Xin projected the perspective model of mobile base with nano molecules on the conference table, removed the energy system and replaced it with the model of a small fusion reactor.


    Watching Chen Xin put the fusion reactor into the mobile base, and the interior of the mobile base automatically adapted to the volume of the small fusion reactor, several staff members had a glimpse, and felt that this technology of nano molecular projection drawing was very practical and intuitive.


    Of course, this kind of feeling is just a flash, and we soon pull our thoughts back.


    The perspective model of mobile base projected by Chen xinsou not only simulates the structure and equipment of mobile base, but also simulates all the original electrical circuits.


    With all the design drawings of the mobile base, it''s not surprising that Chen Xin has done such a thing.


    For other staff, this saves them the trouble of looking through the mountains of drawings. They only need to intuitively feel from the model to know the routing of the mobile base.


    But in the face of the complicated cobweb like internal electrical circuit of the mobile base, some people still feel that it is better to go back to the drawing, at least not so dizzy.


    Inside the huge mobile base, almost every place needs electricity, and natural lines are indispensable.


    In the drawing, it may be just a thin schematic line and symbol, but in reality, it may be dozens or even hundreds of wires and cables. When these cables are completely presented in front of you, what they weave is a huge web, which is far more complex than spider web.


    In particular, you have to distinguish the purpose of each line and where it will be connected in this dense network. It''s really a waste of time.


    Fortunately, Chen Xin also knew this. After making some adjustments, he concealed the complicated and detailed lines, leaving only the main ones.


    This is quite intuitive, just like a person, if all the blood vessels in his body, including capillaries, are drawn in great detail, it will undoubtedly make him dizzy, and he can''t tell which is which. But if it''s just aorta and main vein, a junior high school student can tell what these blood vessels are for.


    "Academician, if you look at it like this, it''s not easy to connect the line!" Looking at the lines projected from the mobile base, a staff member in charge of electrical design said with some embarrassment: "the power output from the small fusion reaction furnace needs to be adjusted through the transformer. In addition to the lines supplied to the weather controller, it also needs to be supplied to the original power system and other internal electrical equipment.


    Not only can there be no reduction, but also need to ensure the normal operation of the original equipment, can not cause interference... Coupled with the internal structure adjustment, the various functional modules of the weather controller are packed, which is equivalent to redoing the entire electrical circuit! "


    "Why, can''t you do it?" When Chen Xin heard the staff''s words, he didn''t say anything, but turned his eyes to the other side, showing a trace of severity.


    It''s not that he is unkind and has to embarrass the staff, but that this is the simplest problem in the whole project.


    "No! It''s difficult to show our ability, isn''t it? " However, the staff member laughed and looked confident.

 Chapter 574

    When new work starts, new materials and supplies need to be transported in China.


    As a result, the number of transport planes between China and Lucia did not decrease because of the success of the test, but became busier and busier.


    These transport planes carry not only the materials transported from China, but also the staff who went back to visit their relatives and had finished their holidays.


    For a short seven day holiday, it will take at least two days to go back and forth on the road. For those who live far away and more remote, it may take three or four days to go home. After a short reunion with their families, they will have to return to a foreign country. This is a very cruel thing for anyone.


    But in this era, not only the staff, but also more people choose the same path. In order to make their families get a better life, they choose to leave their families to work hard and rebuild their old homes bit by bit with their own hands.


    It''s hard to bear the separation from your family, but it''s far more important than the reunion to rebuild your home and make your family live a better life.


    So although we didn''t give up, we resolutely set foot on the job.


    But today the flight landed in Lucia, in addition to the return of the staff, but also one more person.


    After the plane landed, the staff quickly got off the plane, and the ground crew quickly unloaded the cargo in the cabin and began to check and repair the plane.


    "It''s so cold!" The woman with helmet can''t see her face clearly walked out of the engine room. She couldn''t help exclaiming. She quickly adjusted the value of the protective clothing and followed the others to the room.


    She just flew over from China, but she didn''t adapt to the cold temperature of Lucia. Although she was wearing protective clothing, she didn''t adjust the cold resistance mode of the protective clothing. She was shocked by the low temperature of more than 100 degrees below zero on Lucia''s side, and felt a sharp chill.


    Following other people into the room, the woman felt better and marveled at the bad environment.


    Before the disaster, she had not been to Lucia, but Lucia at that time, even in winter, was not so cold.


    Now Lucia has really achieved the real sense of the death temperature, dripping water into ice is not enough to describe the terrible cold.


    Women clearly know that in this low temperature environment, if there is no protective clothing, the body or skin will be directly exposed, within a second, will be directly frostbite.


    The speed of frostbite is not much slower than that of putting hands into liquid nitrogen. It can be said that it freezes through in minutes.


    After all, there is no difference between - 100 degrees and - 190 degrees in frostbite.


    If it wasn''t for the protection of protective clothing, no one would want to stay in such an environment for another second.


    Looking at the frost on the helmet of the protective clothing, the woman can''t help but take a deep breath and recall the warmth and comfort of her home. She can''t help admiring these people who came to work for Lucia.


    In such a difficult environment, it''s true to ignore life and death.


    Although strangers are unlikely to enter, the inspection of the base is still very strict.


    The soldiers in power armor and two heavy machine armour guard the main entrance to the base. Even if they know each staff member, they still check their identity one by one, check their certificates, and let them enter the base after they are confirmed to be correct.


    When the woman saw this, she quickly took out her passport and ID card, which she had prepared specially, and held them in her hands for verification.


    The low temperature of more than 100 degrees below zero means that even steel has to freeze. Of course, the original paper is not good enough. Now the materials used for writing are made of special materials, some of which are similar to plastic materials, so that they can withstand the cold weather.


    When it was the woman''s turn, she handed all the documents to the soldiers. The other side looked through them for a long time, and then asked, "are you visiting relatives from China? Who are your relatives? Face is really big enough to let you come from China. "


    It''s no wonder that soldiers have such doubts. After all, in this big environment, it''s very difficult to visit relatives in China. There won''t be a pass and permission at leisure, let alone the possibility of visiting relatives across the country. This is a rare thing before the disaster.


    This makes people wonder what kind of identity background a woman has, and how she can visit her relatives at such a time.


    "Academician Chen Xin." The woman gave a smile and said a name that surprised the soldiers and took for granted.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "The support here is not necessary. After it is put on the mobile base, all the supports and structures have to be redone. There is no need for such load-bearing structures." Chen Xinzheng and a group of staff face the huge metal structure in front of him and draw on the drawings to discuss where to give up.


    The huge steel structure support is the base part of the weather controller. In those days, the suvians built it very solidly, but now it has become a burden and hindrance.


    "These are really not necessary structures, but if they are installed on the mobile base, they still need load-bearing support, right? In addition, don''t these brackets need to be designed for support? " One of the staff members seems to be trying to save a little material, intending to use the brackets.


    After careful consideration, Chen Xin still shook his head: "these supports are too big. It takes time and effort to dismantle them. Even if it''s necessary to cut them, what do you take to cut such a thick steel frame? Although it really should be able to save a little bit now, it''s not worthwhile to save more manpower for this material. "


    Hearing Chen Xin''s words, the staff also felt that it was true, but they still sighed: "Oh, what a pity."


    "It''s no pity. As long as we can rebuild our homes, these things will only be better in the future." Chen Xin said seriously, and then he wanted to explain his work to the staff: "next we will..."


    However, at the beginning of Chen Xin''s speech, a shout nearby interrupted him.


    Chen Xin turned his head and saw a soldier leading a woman in a familiar protective suit to him.


    In his surprised eyes, the woman opened the helmet of the protective clothing, revealing Mo Qingyan''s happy and angry face: "ah Xin!"


    "Qing Yan? What are you doing here? " Chen Xin was really surprised. He didn''t know how Mo Qingyan came to Lucia. How did she come so far?


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 575

    Mo Qingyan''s arrival has really made Chen Xin''s life much better. After all, it''s more comfortable for someone to make a bed and make clothes for you every day.


    However, although ten Zhang soft red gentle, but Chen Xin did not indulge in gentle Township, forget the business.


    After several rounds of discussion and careful study, the project team finally came up with a preliminary reduction and transformation plan for the weather controller.


    In this scheme, the first thing to do is to divide the whole weather controller into different functional modules according to its functions.


    Then, according to the function of each module, the unnecessary modules are removed, and after adjustment, they are combined together to form a new weather controller in the way of reducing the volume as much as possible.


    Then, on the basis of this weather controller, it was installed into the adjusted mobile base.


    Of course, this scheme is obviously impossible to be put forward by ordinary researchers.


    After all, they will not propose such a scheme that the original weather controller is disassembled, reassembled according to different modules, and then put into the mobile base. After all, instead of doing so, it is better to directly build a new weather controller, and then build a new mobile base according to the weather controller.


    However, for Chen Xin, who holds the upgrade function of the system, this is an easier solution.


    The division of weather controller module area has been completed long before the scheme comes out. Now each area has been divided according to different functions. Although the relevant disassembly work has not started yet, which parts can be removed, which parts can be reduced, and which parts can not be moved have been confirmed.


    These modules can be disassembled directly after the plan starts.


    It''s just that although things are going well, some people still find Chen Xin and put forward the idea that the upgrading and transformation of the existing weather controller is too expensive, so it''s better to build a new one in China.


    Of course, this idea is not a problem. It can even be said that it is a more practical approach than the scheme they are using now.


    After all, the technology of this weather controller has been figured out, and it is only for further research and reservation for the renovation plan.


    Although the cost of rebuilding one may be higher, compared with completely upgrading the existing weather controller, the cost is not much lower.


    Moreover, in the process of manufacturing weather controller, we can thoroughly master the manufacturing technology of weather controller, optimize and upgrade it, and build a new weather controller with lower cost and high efficiency.


    It is also said that although the existing weather controller has been upgraded and renovated, it is something of the suvia era. Unless Chen Xin completely upgrades it and even replaces the overall design, those designs of the suvia era really belong to something that should be eliminated.


    These designs did not forget to replace in the previous upgrade process, but belong to the part that can not be replaced and will not affect the use of weather controller.


    For example, the suvians designed an old structural form of cement support. Although it can be replaced by a more convenient and durable new metal support, since the cement support is not damaged, there is no need to replace it.


    Correspondingly, such a design is not uncommon in the weather controller.


    Before we have a thorough understanding of this technology, we are still conservative and hesitant about the transformation of the weather controller.


    In order to avoid the modification of some key parts, the function of the weather controller will be affected.


    But now that we have basically understood the weather controller, and we have to dismantle and upgrade it as a whole, some old designs can really be thrown away.


    Without Chen Xin''s system upgrade function, it really costs a lot of unnecessary investment to do so. However, with the system upgrade function, many things are much simpler. Compared with rebuilding a new one, it will save a lot of investment.


    Of course, Chen Xin didn''t stop the idea of building a new weather controller, and sent the proposal back to China.


    In his opinion, the more the weather controllers, the better. The greater the range of influence, the better. It''s better to have one in each region. When it''s time to start at the same time, it may be able to change the weather in a large area at one time, affect the meteorological system of the whole world, and restart the meteorological system.


    China also attaches great importance to the technology of weather controller. Chen Xin''s suggestions and related research results of weather controller are very valuable information for China. Naturally, China is also considering whether the idea of building a new weather controller is feasible.


    However, this kind of thing will not be able to come to a conclusion for a moment and a half. Chen Xin''s work in Lucia can''t be delayed either. Chen Xin''s work will continue to focus on Lucia''s weather controller before it is explicitly stated in China that it will not be abandoned or other disposal will be carried out.


    In addition to the weather controller, the mobile base will also be transformed.


    As the base and mobile platform carrying the weather controller, the mobile base should make enough space first.


    As a result, the mobile base is now parked in a hangar in the base, and it has to accept the general reconstruction project like rifling and overall reconstruction.


    Naturally, the crew of the mobile base moved down from above and moved to the base for temporary residence, while the personnel cabin, hangar, garage and other spaces of the mobile base itself were completely emptied and planned to be demolished.


    Such a large-scale transformation is somewhat difficult to accept emotionally for the crew who have just adapted to the work and life on the mobile base.


    It took me several months to get familiar with this vehicle and my job, but now I say to dismantle it, which is more or less uncomfortable.


    However, these soldiers quickly accepted the fact and understood that the purpose of such transformation was to make better use of the weather controller and the mobile base, so although they were upset, no one really said anything irrational.


    As for the transformation of the mobile base, Chen Xin also attached great importance to it. After the transformation, he took charge of it himself.


    After all, after the demolition, he still needs to use the system upgrade function to upgrade the mobile base to complete all the transformation.


    If there is no system upgrade, it''s just to remove an internal space in the mobile base, but there''s no way to put something as big as the weather controller into it.

 Chapter 576

    In the hangar of the base, the huge mobile base is no longer what it used to be.


    The upper deck has been almost completely disassembled, the internal space has been emptied, and the middle compartment has been removed from the top deck to the bottom garage.


    If the mobile base before dismantling is a huge thing full of deterrence and sense of power, it is just a huge metal frame after dismantling.


    Although not all the parts have been emptied, but the upper hangar, the public space of personnel cabin and the garage on the ground floor have been emptied, it still makes the whole mobile base much thinner.


    "Academician, the empty space is still unable to accommodate the weather controller!" A staff member, holding the drawing, standing beside the mobile base, was frowning and said to Chen Xin, "according to the current calculation, it will take at least three times as much space to put the weather controller in. It''s impossible at all."


    Although the staff have been trying to reduce the size of the weather controller as much as possible during this period, so far, even if many unnecessary parts are removed, it is still a huge thing and can not be put into the mobile base at all.


    Of course, Chen Xin knew this, and didn''t say anything about it. He just nodded his head and said, "don''t worry about this. First, install the fusion reactor on the mobile base.


    As for the weather controller, first try to reduce the volume of each part. It''s really not good. You can expand the volume of the mobile base! There are more ways than difficulties, step by step. "


    "Yes, academician." The staff also understood this, so they nodded and went to their work.


    Chen Xin has entered the mobile base which has been basically demolished.


    This is one of the two mobile bases that he upgraded when he was in Siberia. The other one is still in China, and Chen Xin has not been involved in the specific purpose.


    But now this one, most of the internal structures have been removed, will be used as the bearing platform of weather controller.


    The bottom garage originally used to place vehicles will be used as the installation location of energy transmission and conversion modules. The surging energy generated from the small fusion reactor will be input into the weather controller to provide sufficient energy for the weather controller.


    It sounds like it''s possible to connect a fusion reactor directly to a weather controller, but it''s not.


    The fusion reactor made by Chen Xin uses magnetic fluid to generate electricity, which is different from the traditional high-temperature boiling water. It uses ionized gas to pass through the strong magnetic field at high speed. Under the influence of Lorentz force, positively charged ions and negatively charged ions deflect in the opposite direction and fall on the opposite electrode plates to form the positive and negative electrodes of the power supply.


    Of course, the benefits are obvious, such as the continuous production of nuclear fusion raw gas intake heating reaction exhaust power generation product separation recovery and reuse of non fusion nuclei.


    But at the same time, although this reduces the requirements for the reaction vessel, there are certain requirements for the power consumption, because if it can not bear such a high power output, the line will be burnt out.


    Therefore, some equipment is needed to restrain and tame the electric power of this violent flood, so as to make it more docile, and then it can be transmitted to the weather controller.


    This is just like the high-voltage electricity can not be connected to the civil electrical appliances, it needs the transformer for conversion.


    Moreover, although the weather controller needs a large amount of energy in the process of operation, this kind of energy can not directly connect the current just output from the fusion reaction furnace to the machine, which will probably burn the machine directly.


    The energy transmission and conversion module, on the other hand, is also a safety measure of the weather controller to avoid the machine failure or damage due to the current problem.


    Because of this consideration, in addition to building a nuclear power plant for the weather controller as a power supply facility, the suvians also prepared a dedicated substation and transmission line for the weather controller.


    But when it is installed on the mobile base, the nuclear power station can be replaced by a small fusion reactor, and the variable power station is not so good.


    Fortunately, the convenience brought by the development of science and technology is not only the improvement of power generation, but also the smaller substation equipment.


    Chen Xin vacated the garage on the ground floor, which is intended to be used to install the energy transmission and conversion modules after the upgrading of modern technology.


    Thanks to the fact that technology has improved a lot compared with that of the suvia era, the garage of the mobile base can accommodate these modules.


    In addition to these auxiliary equipment, the weather controller itself still has many other modules. The volume of these modules is not small at all. Even if the public space of the personnel cabin, the upper hangar and the top deck of the mobile base are vacated, it is still difficult to install the giant weather controller.


    Not to mention anything else, the antenna used by the weather controller to transmit microwave is a huge object with a diameter of more than 50 meters. Although it can be erected outside the top deck of the mobile base, it is still too large to be placed.


    It is difficult to install an antenna alone, not to mention the coil used by the weather controller to generate microwave. It is a huge circular coil with a diameter of more than 100 meters. Unless the structure is changed, it cannot be inserted into the mobile base.


    Moreover, the weather controller has more than these two components. In order to prevent the microwave from escaping, the protective cover that needs to be added should cover the whole machine


    So even if the empty mobile base has a large internal space, which is no less than the hangar of a heavy aircraft carrier, it is still difficult to put in such a huge thing as weather controller.


    Chen Xin must find a way to reduce the size of the weather controller, or expand the internal space of the mobile base.


    Fortunately, both of them are not difficult for him. As long as he uses the system upgrade, it can be done in a moment.


    What the mobile base needs to do is to enlarge, lengthen and expand its internal space, but the weather controller is not easy to do.


    After all, even if Chen Xin''s cognition and thought can completely control the result of the system upgrade, Chen Xin is not a real professional after all, and it is difficult to guarantee that the upgrade route he chooses must be the best.


    Therefore, it is safe to wait for researchers to come up with a suitable scheme, and then upgrade the weather controller according to the scheme, so that it can be put into the mobile base.


    Now the mobile base doesn''t need any big changes, but the weather controller needs to reduce its size bit by bit.

 Chapter 577

    For the weather controller disassembly and transformation work is very smooth, but the progress is still very slow.


    After all, from a practical point of view, it is still not a simple job to reduce the size of a huge machine, even with the right idea.


    Chen Xin had expected this for a long time. Although it would be an instant if he used the system upgrade, he still followed the staff to analyze and study it bit by bit in the most simple way to confirm all the transformation processes.


    Only after all the processes of a module have been confirmed and the transformation scheme and plan have been finalized, can Chen Xin launch the function of system upgrading and directly transform the finalized transformation scheme into reality.


    Although this is relatively slow, the effect is the best.


    After all, if Chen Xin shrinks the entire weather controller directly, there will be many black boxes in it, which will require the staff to spend a lot of time to analyze again.


    Not like now, although the efficiency is a little low, at least the technology used in each step has been thoroughly understood, and there is no unknown black technology.


    Of course, the cost of doing so is that it took Chen Xin almost a week to install the energy transmission module of the weather controller on the mobile base, and it was only a rough installation, and later they had to adjust it according to other modules.


    So far, in addition to the energy transmission module, only the small fusion reactor has been installed in place, replacing the original energy system of the mobile base.


    This small fusion reactor is not the model that Chen Xin made at the beginning, but the model that domestic researchers made through him at the beginning, after having a thorough understanding of the relevant technology, with the technology mastered by the country.


    This reactor may not be as efficient as Chen Xin''s original model, but at least all the components can be produced, all the technologies have been mastered, and it can be mass produced with the help of domestic industrial system.


    If it''s just an organization or a small country, it doesn''t matter whether they can replicate that device. After all, it''s small-scale and needs to be solved only if there is one, rather than large-scale application or mastering the core technology.


    However, for a large country, if a technology can not be applied on a large scale, or if there are black box parts that are not thoroughly understood, then the technology can not be compared with the technology that can be applied and promoted on a large scale, and the technology that has been thoroughly understood.


    Although the sophisticated black technology is very attractive, it can''t be mastered, applied or promoted, and the best technology is of little significance.


    This is also the reason why the state clearly knew that Chen Xin could provide a lot of black technology here, but still let him upgrade the original technology as far as possible, or cooperate with other staff to carry out research and development, and try to analyze the black technology he developed as far as possible, instead of using it directly.


    This is true for Yan Kingdom, and it is also true for Lucia.


    Although they built the energy tower with the aid of Yanguo to solve the heating problem of the capital, the key technology of the energy tower is in the hands of Yanguo people. They can only build a new energy tower by purchasing the core of the energy tower from Yanguo, which is undoubtedly a very frustrating thing for the official of Lucia.


    However, no matter how much they negotiated with Yanguo, Yanguo''s senior management did not agree to provide them with the key technology of the energy tower. Instead, they only provided the finished product packaging core, not the technology.


    Even the number of packaging cores will be limited and the supply will not be open.


    Under such circumstances, although lucians can only hold their noses, they still hope to be able to analyze the relevant technologies.


    Through various channels, we learned that Chen Xin was the scientist who developed the key technology of the energy tower, and some ideas naturally appeared in some people''s minds.


    They are not so stupid as to think that they are going to take any unfavorable idea against Chen Xin. After all, if something happens to an important scientific researcher like Chen Xin, it will be a result that we do not want to see for both countries.


    What these Lucia officials think is just to set up some key nodes of this technology from Chen Xin.


    They don''t even expect to obtain a complete set of technology. After all, it''s really impossible. Moreover, Lucia''s scientific research strength is not too weak, and the principle of the energy tower is not too complicated. After Lucia''s scientific researchers participated in the construction of the energy tower, they also found out the relevant operation mechanism of the energy tower.


    But the key core technology can not be found out by participating in the construction. They really don''t understand how the energy tower can extract so much heat energy from the underground so efficiently.


    You know, the heat supply range of the energy tower''s pipeline is 10 km in radius. Although it has a lot to do with the transmission capacity of the pipeline, it also reflects from the side how much heat such an energy tower can provide.


    But if you want to know this, in addition to trading with Yanguo, you can only get it from Chen Xin, the inventor.


    The way to trade with Yanguo has been blocked, so we have to find a way from Chen Xin.


    After summing up, they came up with a very good idea, though not brilliant.


    ¡­¡­


    "There is something wrong with your seed bank in Lucia. Would you like us to help maintain it?" Chen Xin looked at Lucia, a female scientist with silver hair, and frowned: "can''t you solve this problem yourself?"


    "Sorry, Chinese scientists have tried, but the heating system of the seed bank has reached the limit. If the temperature drops further, the temperature in the seed bank will break through the critical value, and then a large number of precious plant seeds and animal embryos stored in the whole seed bank will be frozen." With an anxious look, the female scientist sincerely said to Chen Xin, "these seeds and embryos are very precious to human civilization. We have tried our best. There is really no way to ask you for help. Please help us!"


    Chen Xin hesitated for a moment. In fact, he didn''t want to deal with this kind of thing, but he still asked the female scientist, "how do you want us to help?"


    "I know that you have helped our country build an energy tower in the capital, which can provide continuous heat for the capital and protect the life of the people in the capital, so I hope you can help us build the same energy tower in the seed bank, so that we can protect the seed bank!" It seems that the female scientists have already conceived a plan before they come here, and they are full of expectation, they said to Chen Xin.

 Chapter 578

    "Building power towers? Seed bank? Why do you come to me when you should go to your official Chen Xin looks at the female scientist in front of him. Although he doesn''t look happy or angry, he also shows his resistance to what the female scientist is asking for.


    It''s true that Chen Xin has mastered all the technology of the energy tower, but this kind of thing should be solved through diplomatic channels between the two countries, rather than directly coming to the door, as if he would help the lucians build the energy tower.


    "We have contacted the authorities, but they can''t help us now. The country has been attacked by an epidemic. The power of the authorities is basically used for reconstruction, and there is not much power to help us protect the seed bank." The female scientists look sad and obviously feel very desperate for such a situation.


    She covered her face and seemed to be suppressing her crying voice. With a slight choking voice, she said, "we have no other way. If there is no other way to change the temperature of the seed bank, we can only watch the seeds and embryos freeze!


    The government has no spare power to help us. Now they can only manage themselves. I also know about the energy tower from a friend. Now this is our only hope!


    I can only ask for your help! Please see, for the sake of mankind and the earth, help us! Please save those seeds and embryos, they are the key to rebuild our home in the future! "


    Chen Xin looks at the woman scientist who is hiding her face and crying. Although she believes 70% or 80% about this, she still has some doubts in her heart.


    It''s not that there''s something wrong with what women scientists say. From all aspects, there''s nothing wrong with what women scientists say.


    In the face of a global disaster, countries with a little ability in the world will be ready. A big country like Lucia should prepare its seed bank for ecological reconstruction after the disaster.


    It is also normal to say that the seed bank is in danger of freezing because of low temperature.


    After all, before the disaster, the temperature in winter in Lucia could reach minus 40 or 50 degrees. Needless to say, now, the temperature is more than minus 100 degrees. Chen Xin believes that no matter how the original seed bank can withstand the harsh environment, I''m afraid it hasn''t considered the normal operation at such a low temperature.


    Not to mention that the whole country is not in normal operation because of the epidemic in Lucia. It is very normal that there is a problem in the seed bank.


    However, the female scientists went directly to him for help, which became a problem.


    According to the normal procedure, it should also be the seed bank represented by female scientists who reported the problem to Lucia official. Lucia official was unable to solve the problem and thought that the energy tower could solve the problem.


    It''s normal to be here, but it''s time for Lucia to send someone to talk with Yanguo about support, or directly buy the core of the energy tower.


    There is no official way to solve the problem, so that female scientists can directly find themselves and look like they have no way to ask for help.


    Isn''t it someone playing something? Chen Xin had this idea in his mind, and he was a little more alert.


    Chen Xin can''t help thinking otherwise. After all, during Lucia''s time, all kinds of bullshit have come out one after another. He has seen all kinds of guys full of ambition and crooked ideas. Who can guarantee that the female scientist in front of him is not such a person?


    Thinking of this, Chen Xin also made clear his attitude and said to the female scientist, "sorry, I can''t help you. If you need help, you should contact the relevant departments of our country through the official departments of your country through formal channels.


    Whether you need material assistance or technical support, you should talk to the relevant departments of our country about it, not come to me for personal help.


    We do have a part of the task of helping you in Lucia, but all we can do is to deal with the domestic transportation of materials and provide you with medical and related technical support.


    As for other things, I don''t have the right to promise you anything and I can''t provide any help. If it''s just you, I can consider recruiting a foreign scientist on behalf of our scientific research department.


    I can''t do anything else. So please forgive me. If your seed bank is really in crisis and needs help, please go to the official channel for help. "


    Chen Xin''s words can be said to be very cold and inhuman, but this is the reply in common sense.


    Faced with Chen Xin''s indifferent attitude, the female scientist burst into tears and cried out: "no! You can''t do this! Seed bank is the wealth of all mankind! It is related to the reconstruction of human civilization! You can''t do this! You should help us


    Said, she even want to rush to Chen Xin in front, but immediately by the side wearing exoskeleton soldiers pull, quickly subdued.


    Looking at her tears, Chen Xin shook her head and said, "I''ve already told you the way. Instead of asking for help from your own authorities, you''re just messing around with me. Do you think I''ll agree to help you? I''m sorry, it''s impossible. Send her out and give the person to Lucia''s official. "


    With that, Chen Xin ignored the crying female scientist and left the reception room.


    For Chen Xin, this incident is not worth his attention. However, what happened just now made him alert. He specially told the commander in charge of security that he wanted to strengthen security measures recently. At the same time, he also informed China about this incident.


    Chen Xin may not be good at this aspect, but there are not many professionals in this aspect in China. Just a little analysis can tell the fact that lucians are concerned about the energy tower technology.


    However, even the people in the domestic intelligence departments feel very strange. It seems too simple, rude and direct to directly ask a female scientist to come to Chen Xin.


    Unless Chen Xin is similar to the kind of fool in the movie who can sell the national interest for personal friendship and ignore the three words of others, who wants to die for the sake of all mankind, it is impossible to agree to help the female scientist.


    In the face of such a situation, as well as the analysis given by China, Chen Xin, after some consideration, took the initiative to hope that China would send people with experience in this field to his side.


    Chen Xin used to be an Internet writer. He has heard about KGB for a long time, not to mention the legendary existence of KGB''s swallow. He doesn''t want to be the material of spy films. It''s better for professional people to do professional things.

 Chapter 579

    Naturally, China attached great importance to Chen Xin''s reaction. After a little discussion, a whole security team was sent to him.


    "Hello, academician Chen. I''m from GA Bureau. You can call me Ye Yu. I will be responsible for your safety in the future." A woman who looks more than 30 years old and looks very capable stands in front of Chen Xin and introduces herself to him. At the same time, the team members who are still sorting things behind her also put down their work and stand in a row in front of him.


    Chen Xin glanced at the past. In addition to the woman who claimed to be Ye Yu, there were five members of the security team behind her.


    It looks tall, short, fat and thin with their own characteristics, but it doesn''t have the feeling of outstanding appearance. It seems very common only from the aspect of face.


    Ye Yu noticed that Chen Xin looked at his team members, so he introduced them to him: "these are all my team members. We have performed many tasks together, and we have been responsible for protecting important leaders and foreign guests. We have rich safety experience. We will be responsible for your safety problems. You can trust us on this point."


    For Ye Yu''s words, Chen Xin didn''t give much reaction, just nodded and said: "I''m sorry to trouble you to come to Lucia from China. After that, I''ll give you all my safety."


    Chen Xin''s words are polite, but one of Ye Yu''s team members, a skinny man who looks a little smart, suddenly says: "this is not trouble! Now that we are able to come out to carry out our tasks, we have to thank academician Chen for your help! "


    "Skinny monkey, shut up Ye Yu saw his team member so suddenly cut in, immediately denounced a dissatisfaction.


    Although it''s true that as the security personnel of GA Bureau, what they are responsible for is to protect the important people from all walks of life, in this kind of environment, they don''t have much work to do, and the whole country is still peaceful, so they have little use.


    Although people like them have nothing to do is the greatest happiness for others, after all, the environment is different, and leisure also makes them feel reborn.


    Now we are able to come to Lucia for a mission. We are still very happy that we can use it for our country.


    Because of this, the team member called "thin monkey" is a little too excited, but ye Yu doesn''t want to leave a bad impression on Chen Xin because of him.


    Chen Xin didn''t care about it. After nodding to them, he said to Ye Yu, "I think you should also understand the situation. Lucians may be thinking about my energy tower technology, so they have a plot. Before, they sent a female scientist to ask for help, but I blocked her back. But they must have more than one means, so it''s up to you!"


    "Please rest assured, academician Chen, we have dealt with KGB. Although this is their home court, we have not carried out relevant tasks and will not let you encounter danger or let them plot to succeed." Ye Yu assures Chen Xin seriously.


    It has been discussed in China, and we do not intend to share the energy tower technology with Lucia, but only provide them with packaging core. Therefore, according to the judgment of relevant departments, the female scientist sent by Lucia is probably just the beginning, and we must be vigilant about what means they will use later.


    As a matter of fact, the progress of lucians'' follow-up action is not slow. They have passed on the demand of building a new Taiwan energy tower to China through formal channels.


    China did not refuse lucians to buy the core, but in terms of quantity, China did not meet all the needs of lucians.


    Lucians plan to build energy towers in several major cities. Together with the energy towers in the seed bank, they plan to build seven energy towers.


    China did not fully agree with this. On the grounds of insufficient production capacity and shortage of relevant technical personnel, only three energy tower cores were provided for Lucia, and Ye Yu came to Lucia with these three energy tower cores.


    They don''t need Ye Yu to manage the energy tower and core affairs. Their only task is to protect Chen Xin''s safety and prevent lucians from spying on him and his technology.


    "Academician Chen, this is Daqiang. After that, he will be responsible for protecting your safety. If anything happens, please cooperate with Daqiang and follow his instructions." Ye Yu called a young man who looked very tall, and introduced him to Chen Xin. At the same time, he asked for help.


    This is often the most troublesome thing for them to do security work. If the target does not cooperate with them, to do some dangerous actions is undoubtedly the last thing they want to see for those who are in charge of security work.


    Chen Xin didn''t have any resistance to this. He nodded his head and said: "in case of danger, I will act according to the instructions of professionals. Don''t worry about this. I just hope you can check out the possible danger around me."


    "Don''t worry, that''s what we''re here to do." Ye Yu nodded and introduced the remaining four players to Chen Xin.


    Although the "thin monkey" of the four looks dry and thin, he is a blasting expert. His main responsibility is to check the explosives and avoid the safety threat to the target person they want to protect.


    Among the other three, one is a sniper named Lao Wei, one is a network security expert named Zhang Ming, and the last one is a communication expert named Zou Jun.


    Among them, network security experts and communication experts are of little use in this situation. Their main task has changed from maintaining network and communication security to protecting Chen Xin.


    As for the sniper, Chen Xin thought that he might not be useful in Lucia''s environment, but Lao Wei explained that he was not the kind of sniper that Chen Xin thought was lying on the commanding height to snipe at the target.


    On the contrary, he is the kind of anti sniper who guards the target and counterattacks quickly after the target is sniped.


    Chen Xin was a little surprised. He had never heard of this kind of sniper. After all, he had a sniper''s girlfriend and knew about snipers. But this kind of anti sniper was the first time he had heard of it.


    "Snipers like us mainly judge the location of enemy snipers at the first time when the target is sniped, and counterattack at the first time." Lao Wei''s expression is very serious, explaining his work to Chen Xin: "when encountering the situation of enemy sniper, many times the enemy sniper''s first shot, even if it hits, will not be able to ensure the killing, so most of the time he will make up the gun.


    And my job is to find out the enemy sniper immediately after he shoots, and then carry out anti sniping, so as to eliminate the possibility of the other party''s re shooting. "

 Chapter 580

    The arrival of the security team has built a security defense line for Chen Xin. Although Chen Xin is unlikely to encounter danger in the base, after the investigation of Ye Yu and others, some security risks have been found in the base.


    Some of these hidden dangers are just security loopholes that the staff didn''t notice. If they can''t fill in them, they will be over. However, some of them are the technology that Lucia is thinking about.


    For this point, Chen Xin did not publicize this matter under Ye Yu''s suggestion, just checked out all the security risks and blocked the loopholes.


    As for the handling of this matter, after collecting the evidence, it was reported to the relevant state departments for them to deal with.


    Although this incident had a certain impact on the relations between the two countries, it was overturned after Lucia took the initiative to soften up when both Yanguo and Lucia wanted to maintain the current mode of cooperation.


    However, although this matter has been turned over, lucians'' peeping at the energy tower technology of Yanguo has not stopped.


    Lucia, the core of the three towers, allocated two of them to the other two important cities in the country, and the remaining one to the seed bank.


    With the construction of three energy towers at the same time, the demand for engineering and technical personnel has tripled.


    Under the pretext of insufficient technical personnel, Lucia once again issued a request for technical assistance to Chen Xin.


    In the face of Lucia''s request, Chen Xin refused.


    Chen Xin can refuse to ask for help in the private name on the pretext of not getting the official permission and not conforming to the process specification. However, Chen Xin can only procrastinate and not reply to the requests that are sent in the official name and conform to the specification in all aspects at most.


    Although procrastination is also a way, Chen Xindao can''t do such a thing. After all, the construction of the energy tower really concerns the life and death of many people.


    Chen Xin has learned before that although Lucia built a large number of underground bunkers in the tosuvian era and saved a large number of people during the meteorite impact, the subsequent extreme cold and cooling gave Lucia a a heavy blow.


    Originally, Lucia''s winter was very cold, but now it is beyond the limit that human beings can bear.


    Even though Lucia has deep underground bunkers and refuges, it is difficult to resist the invasion of cold. After all, these bunkers and refuges were originally built to resist nuclear war, and they did not consider the extreme situation of extreme low temperature of more than 100 degrees below zero.


    Even if Lucia official did a lot of cold protection measures at the beginning of the disaster, it is still difficult to resist the extreme cold of more than 100 degrees below zero.


    In the first winter after the impact of the meteorite, nearly 30% of the population of Lucia was lost, and a large number of the old, the weak and the poor were frozen to death and frostbite because they did not have enough cold protection measures to withstand the low temperature.


    In fact, this kind of thing is the same for Yanguo. If it wasn''t for the appearance of Chen Xin, who provided isotope batteries and energy towers to solve the heating problem, Yanguo would also freeze to death and die of many people.


    So although Chen Xin can''t give Lucia the technology of the energy tower, it''s still within Chen Xin''s scope to help them build a new energy tower.


    However, having said that, the shortage of technical personnel is indeed a very serious problem.


    Previously, the engineering team sent by Yanguo could be responsible for the construction of one energy tower, but with the help of the Lucian engineering team, it was enough to support the construction of two energy towers, but the efficiency and progress of the project would be slower.


    But there is also an energy tower. There are not enough technicians.


    "So, Lucia, this is a game for us to play?" In the face of such a situation, the thin monkey complained a lot.


    "Even if you know it''s a bureau, you have to break it." Chen Xin shook his head.


    Although he also saw that Lucian had come prepared to participate in the construction of the energy tower, and then waited for the opportunity to obtain the key technology of the energy tower from him, he had to take the initiative to deal with it.


    At this time, Ye Yu suddenly asked: "must academician Chen go in person? Can''t we deploy new technicians from China, or send someone else? "


    "There is no manpower available in China now. The reconstruction work in Southwest China has hindered a large number of effective forces in the country. The technicians want to split one into two. Last time, the team was forced out, so there was no surplus manpower." Chen Xin also felt helpless about this, but he explained to Ye Yu: "as for sending other people to..."


    At this point, Chen Xin made an expression of opening his hands: "the construction technology of the energy tower is still a little complicated. At present, except for the domestic people and the engineering and technical personnel dispatched to Lucia, I am the only one who knows the whole set of relevant technologies, and I am also the inventor of the energy tower. I am the most suitable person to look at this kind of thing."


    "So we have to wade in this game?" Ye Yu also feels a bit headache. As security personnel, their principle is to let the target avoid all possible dangers. But now, knowing that the other party has set up a situation, they still have to step on it. It''s really uncomfortable.


    Although it is said that the other party''s plot is only technology and will not cause personal injury to Chen Xin, as GA, they exist in order to put an end to this kind of thing, and it is impossible to indulge this kind of thing.


    Moreover, taking the initiative to enter the game now is simply putting yourself in a passive position, which is really not conducive to the development of security work.


    Chen Xin is optimistic about this. He said to Ye Yu, "the other party''s goal is the core manufacturing technology of the energy tower. Now that you know their goal and want to block the other party''s hand, you should be able to do it?"


    Chen Xin''s words are inspiring, but ye Yu''s job is this. So even if he knows that Chen Xin is inspiring, Ye Yu can only nod his head.


    "Academician Chen, please rest assured that since we know the purpose of the other party, we will certainly protect your safety and prevent the leakage of technical data!" Ye Yu made a solemn promise to Chen Xin, but after that, she also asked with great concern: "academician, in the process of building the energy tower, where may relevant technologies be leaked? Can you prevent lucians from contacting key technologies in the process of building?"


    "At present, the core of the energy tower we provide for the lucians is packaged in China, and the whole core can not be disassembled. Theoretically, they can not touch the key technology, but if there are any problems in the construction process, I can''t guarantee it." Chen Xin naturally considered this issue.


    Packaging the core and forming the black box of technology can indeed prevent lucians from peeping, but no one can guarantee that lucians will not adopt other ways.

 Chapter 581

    The seed bank built by the lucians is not in its capital, but closer to the Arctic circle.


    It''s not that lucians have a bad brain and know that the temperature will drop, but that they have built the seed bank in such a place to be frozen. It''s that the construction time of the seed bank is not before the disaster, but long before there are relevant plans.


    In fact, countries all over the world started similar projects more than ten years ago. For example, the most famous international seed bank has been in operation for more than ten years and was built in Norway, which is more than 1000 kilometers away from the North Pole.


    Lucians had drawn up a similar plan at the beginning, but the domestic economic situation was not good at that time, and the project did not get enough financial support, so it has been intermittent all the time.


    The address of the seed bank is an abandoned missile silo of the suvian era. Even the refrigeration equipment for storing seeds is added after the seed bank is in operation.


    So when we first built the seed bank, we had the idea to protect these precious seeds with the help of the Arctic cold.


    But no one expected to encounter a meteorite impact, a world-class disaster rarely seen in millions of years, and the entire human civilization would be almost destroyed.


    After the disaster was determined to happen, Lucia officials launched a series of plans to ensure the continuity of the whole country. Among them, the seed bank naturally got attention, obtained sufficient funds and resources support, successfully established, and stored a large number of plant seeds and animal embryos, We even kept 5000 gene samples.


    According to Lucia''s official plan, if all countries in the world could not prevent the impact of meteorites at that time, and the whole country that suffered heavy losses in Lucia was on the verge of collapse, then the seed bank would be the last hope to restart Lucia.


    But no one thought that the global temperature would drop to such a terrible level after the disaster.


    The low temperature of more than 100 degrees below zero makes it difficult to resist even the missile silos built in the suvia era. The whole seed bank has become a veritable ice cellar. Not only does it not need to consider the problem of refrigeration, but it also needs to find a way to heat the internal space, so as to avoid the low temperature directly freezing the plant seeds and animal embryos.


    The previous winter, with the support of Lucia, the seed bank survived very hard, but it was still affected to a certain extent.


    Originally, they were able to support them, but with the invasion of the epidemic, the whole of Lucia was almost paralyzed, and the government had no spare resources to support them, which also made the situation of the seed bank critical, and they could not survive the next winter.


    Moreover, the maintenance personnel of the seed bank also fell ill because of the cold. The shortage of manpower, materials and the coming extreme cold are enough to completely destroy this already precarious seed bank.


    Sitting on the plane, listening to Lucia''s staff introducing the situation of the seed bank, and feeling the slightly hostile gaze projected by the female scientist beside him, Chen Xin felt that he was getting a hot potato.


    Although he knew it was a pit, he had to step on it, which can describe Chen Xin''s current situation.


    However, Ye Yu and Chen Xin are all well prepared. Generally speaking, Chen Xin doesn''t think this pit will pit him.


    The only thing he worried about was whether the lucians would play extra tricks.


    If only during the construction period of the energy tower, Chen Xinzi wants to get some key technology from him in his work, he thinks that the other party can''t get anything out of him. After all, after knowing the purpose of the lucians and their reminding from Ye Yu, Chen Xin still thinks that he can keep a secret.


    But if lucians send a KGB swallow or something to play seduction, Chen Xin thinks that even if he can keep a secret, it will cause a lot of unnecessary trouble.


    Don''t think it''s impossible. During the cold war, KGB swallows were famous. Many scientists who defected to suvia were lured by swallows.


    They are all elite spies selected and trained by KGB. They are especially good at luring targets to take the bait and stealing all kinds of confidential information. In those days, they were really famous, which made people turn pale.


    If you have to take an example, the black widow in Avengers is a classic portrayal of KGB swallows, and the real swallows'' ability to steal intelligence is even more terrible.


    But despite the worries, the work still needs to be done.


    On the transport plane that Chen Xin and Chen Xin are taking now, there is one of the three cores of the energy tower that Lucia officially purchased from Yanguo, which will be used to build an energy tower in the seed bank that can ensure the stable operation of the seed bank in the next cold winter.


    "Mr. Chen Xin, after the construction of the energy tower, it will deliver a lot of heat to the seed bank to resist the cold winter. But if the cold winter is over, we don''t need so much heat, how can we adjust the output of the energy tower?" On the plane, an engineering technician sent by Lucia''s official is asking Chen Xin some technical questions.


    Because the seed bank is close to the polar circle, under the current extremely cold and low temperature, the lucians do not have many available modes of transportation, so they borrowed the transport aircraft of Yanguo to pack and transport the core of the energy tower together with the engineering and technical personnel to the seed bank.


    This also gives Lucia''s engineers a chance to get in touch with Chen Xin.


    In the face of this problem, Chen xinlue thought about it and explained: "the output power of the energy tower can be adjusted, which is very simple. When the energy tower is not needed to operate, just close the pipeline conveying medium."


    Although Chen Xin answered the other party''s question, he didn''t mean to explain it in depth.


    But Lucia''s engineers were obviously not satisfied with the answer, so he asked, "but will it affect the exploitation of geothermal energy? If the pressure of the conveying medium is insufficient, will it cause damage to the underlying formation? "


    "At present, as far as I know, there is no such thing. Even in winter, the temperature in southern China is not lower than your current temperature. China''s energy tower can operate well, and I think your energy tower can also operate well." Chen Xin saw that the other party was reluctant, and he was a little wary, and didn''t say any more.


    After perfunctorily answering the question of Lucia''s engineers and technicians, Chen Xin stopped talking to him and asked the official in charge of Lucia: "how long will it take to reach the destination?"


    "At our current speed, there should be half an hour left." Lucia, the official in charge of the construction of the energy tower, looked at his watch and replied respectfully to Chen Xin.

 Chapter 582

    The process of building the energy tower is poor. Perhaps the only thing worth mentioning is that there is no suitable space for building the energy tower around the seed bank, so Chen Xin creatively put the construction site of the energy tower in one of the spare wells of the original missile launching well of the seed bank.


    This is a design of Lucia''s missile silo. In addition to the silo normally used for launching missiles, there will also be a spare silo of the same specification.


    When the seed bank was rebuilt, the main well was only transformed into a seed bank due to the problem of funds. Later, although they got sufficient financial support, they were not allowed to rebuild the spare well in time, so the spare well was abandoned all the time.


    Although it is a spare shaft, all the specifications are built according to the standards. After cleaning up all kinds of garbage accumulated after decades of abandonment, there is no difference between the spare shaft and the main shaft.


    Compared with the 20 or 30 meters thick snow outside and the construction environment of more than 100 degrees below zero, the construction in the spare well is much easier, and the environment is more suitable for construction.


    However, although it is suitable for construction, since it is a missile launching well, in order to consider the relationship between the bottom and the flame burning during missile launching, the steel and cement pouring is very solid and thick, which brings a lot of trouble to the construction of the energy tower.


    It took the construction team almost a week to drill the deep well for the installation of the energy tower, and it took three days just to drill through the cement layer.


    Later, in the process of building the energy tower, the sure lucians tried various means to attack Chen Xin, in order to get the key technology about the energy tower from him.


    However, Chen Xin, who has made clear the purpose of the lucians, has not been deceived. Although he has questions and answers for the lucians, he has not revealed the key core technology at all, which makes many attempts of the lucians fail.


    Not only that, Ye Yu''s security team also played a great role in preventing lucians from plotting against Chen Xin.


    They even found out the real conspiracy of lucians. The female scientist confirmed that Chen Xin had been worried about KGB swallows. Lucians asked her to find Chen Xin directly just to hide this.


    Just ask a chessman who was used by a crude plan. Who could have thought that she was an elite spy carefully cultivated by KGB?


    Even Chen Xin was cheated. He thought it was just a female scientist with low EQ and poor brain. As a result, he was a shrewd spy beyond imagination.


    This kind of stimulation really surprised Chen Xin, and even couldn''t bear it.


    Fortunately, Ye Yu noticed this in time, and directly pierced Lucian''s plot.


    It seems that lucians are not willing to tear their face. After the identity of female scientists was pierced, they did not make any more explorations.


    With the completion of the energy tower, Chen Xin is not willing to continue to entangle with lucians and goes back to the base directly.


    The upgrading of the weather controller in the base is still in progress, and the project team has come up with the first version of the upgrading scheme.


    After looking at the scheme, Chen Xin did not waste any more time, and directly upgraded the whole weather controller according to the transformation and upgrading scheme.


    According to this upgrade scheme, the weather controller is divided into several modules, and the volume of each module is reduced by about one third after the upgrade.


    Although this is a great achievement, the weather controller still can''t be put into the mobile base.


    The volume of the whole weather controller needs to be reduced by half to fit into the mobile base without affecting the use of the mobile base.


    In this case, Chen Xin did not continue to let the staff spend time on the weather controller. Instead, he upgraded the system to get everything done. Finally, he integrated the weather controller with the mobile base and upgraded it into a new mobile base.


    The newly upgraded mobile base is more than twice as large as the original mobile base. The increase of the overall volume naturally brings the growth of the internal space volume, so that the weather controller after the upgrade can be perfectly placed in it, and there will be no more trouble that it can not be plugged in.


    And after upgrading the mobile base, although the volume has increased, but the improved power system and moving mechanism ensure its mobility.


    In fact, Chen Xin would like to upgrade the mobile base to a floating warship, but after a try, Chen Xin is still persuaded to give up the required survival points.


    Even if the propeller and vector thruster are used as the power, the number of survival points required to upgrade such a floating warship is also a number that will make Chen Xindu painful. It is also several times the number of survival points required to upgrade without using materials.


    The number of survival points needed to upgrade a floating warship is enough for Chen Xin to build several new mobile bases. So he hesitated again and again, but he gave up the idea of floating warship. He just enlarged the size of the original mobile base and put the weather controller in it.


    In addition to accommodating the weather controller, the newly upgraded mobile base has reduced the area of the vehicle garage, the top hangar and the public space of the personnel cabin, but it has been re installed, so that the mobile base will not lose its function.


    Not only that, after the upgrade of the mobile base, the increase of the size also greatly increases the number of people that can be accommodated on it, which is enough for all the people in the base to carry on.


    Now the mobile base is a veritable mobile base, not more like a land cruiser than before.


    The merger of weather controller and mobile base has been completed. Chen Xin''s work in Lucia has also been completed, and he can return to China.


    However, considering that the weather controller and mobile base still need to be tested after the upgrade, Chen Xin did not fly home directly, but planned to take the mobile base and drive back to China as he did last time.


    On his way back home, Chen Xin plans to fine tune and repair the mobile base to make it more livable and make the weather controller more practical.


    The technicians sent to the base to help Chen Xin transform the weather controller naturally want to return home with him, but the rescue team and medical expert team sent to help Lucia still need to stay until the virus problem of Lucia is solved.


    For this reason, Chen xinrang''s commander in charge of security and his special forces also stayed together to continue to provide protection for these medical personnel, while other personnel in the base boarded the newly upgraded mobile base together and prepared to return home.

 Chapter 583

    The huge new mobile base marches on the snow. Although the huge size brings all kinds of convenience, it also has an impact on its March.


    Although the original mobile base also has a huge size, it is only the size of two railway cars parked side by side. In today''s world, which is covered with thick snow, there are basically no obstacles.


    However, after doubling its size, more consideration must be given to its capacity.


    At least where the mobile base used to be, now there are some places that the mobile base can''t pass, and the requirements for the flatness of the ground have become higher.


    The huge obstacle remover in front of the car body will continuously clear away the snow and make the ground as flat as possible, so that when the huge car body moves forward under the support of six tracks, it will not suffer uneven force due to terrain reasons and cause unnecessary damage.


    Although the size has been enlarged, Chen Xin still adopts the crawler forward mode.


    Only from the original four rows of eight tracks to the present six rows of twelve tracks, and the tracks themselves have become wider and longer, which can spread the weight they bear more evenly on the ground.


    The huge crawler makes a huge noise in the process of running, and at the same time, it is constantly producing vibration. Fortunately, the mobile base itself has enough sound insulation design and shock absorption measures, so even in the vehicle garage at the bottom of the car body, there is not much noise to hear and much vibration to feel.


    But if you open the garage door to the outside, there will be a huge noise coming in.


    After the transformation, the mobile base has one more deck than the original one. Apart from the space that must accommodate the weather controller, other parts of this deck are designed as personnel cabin. In addition to the old personnel cabin, all the people in the previous base can be brought on.


    It''s just that the public space used as the canteen has obviously shrunk a lot, so that everyone has to eat in batches and in line. There is no way for everyone to sit at the table at the same time.


    This kind of problem is expected by Chen Xin. Although it is indeed a design defect, it is not an insurmountable defect on the whole. After all, it is not unusual that the canteen can not accommodate all people to eat together at the same time.


    As long as we control the dining time separately, we can solve this problem perfectly. The only thing we may need to worry about is that if the whole staff hold a meeting, the public space may not be enough.


    But then you can use the hangar on the top deck.


    Although about one-third of the top deck area is occupied by the weather controller, the size of the hangar is still larger than that of the original hangar, and the number of take-off and landing platforms protruding from the side has increased from the original capacity of four helicopters to six, half of the original number.


    However, although the hangar has increased a lot, the number of helicopters carried has not been supplemented, so the original number of helicopters still makes the hangar a little empty.


    Now from the hangar, what you can see is not the empty top deck, the island command room and the isolated naval gun. The huge microwave projection antenna is installed on the top deck, just like a huge iron pot.


    It''s just that this pot can''t be used to cook or hold anything. It''s used to project microwaves.


    In this upgrade, Chen Xin also made adjustments to the original naval gun, upgrading it from a 130mm naval gun to a 150 mm dual gun. In this way, it can launch special shells and project chemicals to the designated area much faster, which also makes the response speed of the weather controller faster.


    As for the upgrade of the mobile base under his command, the captain of the mobile base is naturally very happy. Although it means that he has to be familiar with the new environment again, it can not affect his good mood.


    Who doesn''t want to command a bigger warship? If you can be the captain of an aircraft carrier, I''m afraid no one will want to continue to be the captain of a destroyer?


    This joyful mood also made the captain want to better complete his own work, made new strict requirements for all operators on the mobile base, and even carried out several exercises to simulate the response under various circumstances.


    It has to be said that these soldiers are good. Although they have not been familiar with the mobile base for a long time, now they have changed the new environment, they still adapt to the new mobile base very quickly. In the shortest time, they can operate and play a 100% efficiency and function.


    Chen Xin is also very satisfied with this situation. In the past few days after he left Lucia, as the captain and operators became familiar with the whole mobile base, some small problems and irrationalities they raised were solved by Chen Xin''s upgrade.


    Even Chen Xin realized one of his ideas when he transformed the land cruiser into a mobile base last time on the mobile base, that is to add a small planting greenhouse on the mobile base.


    The greenhouse is placed at the rear of the car body, which looks like a piece protruding from the top deck to the second deck.


    The vertical planting mode is adopted in the greenhouse, which still uses the technology of ecological greenhouse for reference. It can carry a variety of crops and solve the food problem for the crew on the mobile base.


    However, the area of this greenhouse is not large, and the output is not much. Although it can solve the food problem, if the whole mobile base points to the output of this greenhouse, it is not enough. It still needs to be replenished from the outside.


    The existence of greenhouse only makes the self-supporting ability of mobile base stronger. Even without external supply, it can also obtain the supply of fresh vegetables, so that the crew on the mobile base will not fall into the situation of septicemia due to the lack of fresh vegetables.


    In addition, Chen Xin also marked a small test area in a corner of the top hangar to carry out some necessary tests, such as making special shells filled with chemicals.


    This test area is not permanent. After Chen Xin and Chen Xin leave the mobile base, it can be cleaned up. However, at present, it needs to carry the task of making special shells and transforming the original ammunition.


    After all, Chen Xin has increased the caliber of the naval gun, but the original shells are no longer matched, and all the ammunition needs to be rebuilt.


    Without Chen Xin, of course, this batch of ammunition would not have been used, but Chen Xin''s system upgrade would not have wasted this batch of ammunition.


    The reason why Chen Xin also made new special shells on his way home is that he plans to conduct several more start-up tests of the weather controller on his way home to test the effect of the weather controller in different environments.

 Chapter 584

    "Bang! Bang! Bang The newly upgraded 150 mm Twin Gun spewed flames into the sky. A special shell exploded at high altitude, making the fire flash in the sky. At the same time, it also spread the chemicals into the air.


    After a second improvement, the chemical has now been replaced by a more diffusible form of dust, which has spread into the sky with the bombardment and rapidly formed a thick cloud.


    "In the process of cloud formation, the diffusion range has reached the test requirements, you can start the weather controller!" In front of the console, an operator was reporting the situation loudly while opening a transparent cover on the console, revealing the red button under the cover: "start?"


    "Start!" The captain, who watched everything nervously, heard the operator''s words, took a deep breath, and then gave the order out loud.


    "Got it! Start the weather controller The operator received the captain''s command, repeated it aloud, and then put his finger on the red button: "count down five seconds, five, four, three, two, one! Start


    As the big red button was pressed, the huge microwave transmitting antenna outside the warship Island spread out and aimed at the position where the artillery cloud just spread out, emitting invisible waves.


    The clouds rolled.


    On the top deck of the mobile base, several high-power searchlights are shining in the direction of the clouds, so that Chen Xin standing on the deck at this time can clearly see that the clouds in front seem to be stirred by an invisible thug, and it seems that a heart throbbing change is taking place.


    "Boom! Click An electric light flashed through the clouds, lighting up the dark sky in an instant.


    Only in the light of the sky at the same time, this accompanied by lightning and thunder, but also let the sky become more manic.


    It''s like a long sleeping dragon is waking up, venting its anger accumulated by deep sleep.


    "I haven''t seen thunder and lightning for a long time." Beside Chen Xin, Mo Qingyan looks at the lightning and thunder in the sky, and sighs in a low voice.


    Because both of them are wearing protective clothing and speak through the communication channel, it''s not as if they need to shout because the wind is too loud.


    Chen Xin looked at the constantly stirring situation in front of him and said with a smile to Mo Qingyan: "in fact, thunder and lightning are not uncommon. It''s just that we are bored underground and seldom come to the surface, so we can''t see it. But in the future, I believe all this will change."


    "Ah Xin, you are so confident!" Mo Qingyan can''t help laughing when she hears Chen Xin say so.


    If others say that, of course, she only thinks that the other party is talking about the scene, looking forward to the future, but the only one who can turn the illusory possibility into the prospective vision is the man beside her.


    Mo Qingyan knows very well that all the scenes in front of her are achieved through Chen Xin''s efforts.


    Chen Xin said that the future will become better, which is not only his own expectation for the future, but also his own promise for the future. He has the confidence and ability to really make the future better.


    While they were talking, lightning flashed more and more frequently in the sky, and the strong wind also became more and more powerful, even making Mo Qingyan a little unstable.


    Just when Mo Qingyan was almost blown down by the strong wind, Chen Xin reached out to help her and held her in his arms.


    Chen Xin didn''t say anything, and there was no so-called embarrassing atmosphere between them. The two men, who are both old husbands and wives, don''t care about this little physical contact.


    However, Mo Qingyan still felt happy and sweet. After all, she was held by her boyfriend.


    Two people nestle together, looking at the constantly stirring clouds in the sky and the more ordinary lightning flash up, the heart not only did not face the storm feeling, but has a feeling full of hope.


    Because the lightning and gale in front of us is not an invincible natural disaster, but a manifestation of human''s manipulation of nature and change of nature.


    Although the performance of the two is the same, but the symbolic meaning is quite different.


    One is that human beings succumb to nature, the other is that human beings defeat nature.


    From the beginning, the development of human civilization is not to conform to nature, but to transform and utilize nature.


    In cold weather, we hunt animals for fur to make clothes instead of growing fur on our bodies.


    From the tree down to the ground life, we can not resist the invasion of wild animals, we built fences and houses to keep the wild animals out of the home, rather than let ourselves grow claws and teeth or return to the tree as monkeys.


    The fire ignites the earth, the flood engulfs the homeland, and human beings never give up raising the rebellious sword to the sky.


    Conquering and transforming nature is what human civilization has been doing.


    The power of fire has been tamed and become the driving force for the progress of human civilization; The flood was intercepted by levees and dams and became a tame River and the cornerstone of agricultural development


    The pace of human beings to transform and utilize nature has never stopped and will never stop.


    Once we couldn''t understand the wind, rain and lightning. We thought it was the power of gods and worshiped them blindly. Even if there were great pioneers who explored the mystery of heaven and earth, and let us understand what is wind, what is rain, and what triggered the lightning, we still can''t control it, we can only adapt to its existence.


    But now, with the continuous thunder in the sky, human beings can finally declare that they have conquered all this at the moment, and let the wind, rain and lightning obey the orders of human beings.


    Facing all this, Chen Xin felt a strong pride in his heart. He even wanted to shout at the sky.


    Just like the warrior who raises his sword in front of the dragon, he challenges the sky.


    Chen Xin thinks so and does so.


    "Ah Roared at the sky, Chen Xin felt that the whole person was happy a lot.


    In Chen Xin''s arms, Mo Qingyan looks at Chen Xin''s roar to the sky, and doesn''t feel that Chen Xin''s behavior is silly at the moment.


    She can understand the feelings and thoughts of this man holding her own. In fact, even Mo Qingyan wants to shout to the sky with Chen Xin to express the suffocation of being forced to live underground since the impact of the meteorite.


    With the roar of Chen Xin, the clouds in the sky seem to have reached a limit and began to rain.


    Although these raindrops have been frozen into ice crystals before they fall to the ground, it is freezing rain rather than snowflakes.


    This is a great breakthrough. Although it doesn''t seem to have changed anything, in fact, a lot of things have quietly changed with the rain.

 Chapter 585

    "Academician Chen, what range of weather changes can weather controllers affect now?" In the communication room of the mobile base, Chen Xin is alone at this time. On the screen in front of him, the person who is making another video call with him asks him about the weather controller.


    "From the previous experiments, the weather controller can effectively affect the weather conditions within a radius of 100 kilometers. If it is before the disaster, whether it is wind, thunderstorm, electricity or frost, snow, hail can do it." Facing the screen, Chen Xin''s expression is confident, but his brow is still frowning: "but in this environment, the temperature is too low, and the rainfall will freeze without landing, and it is difficult to affect the weather continuously.


    Although the previous experiments did successfully produce rainfall, the ice debris that fell to the surface was basically frozen. Although this situation has been expected by me, from the current situation, the practicability of the weather controller still needs to be strengthened. "


    Although Chen Xin is very satisfied with the results of this experiment of weather controller, and even feels that he can challenge nature, it is precisely because of this idea that he also puts great pressure on himself.


    Today''s weather controller can only affect the weather of a city or a small area at most. Although this is already very remarkable, it is not much different from the effect of artificial rainfall before the disaster.


    Moreover, the cost of weather controller to change the weather is much higher than that of artificial rainfall. Although the weather controller can do more, it can not cover up the fact that the practicability of the weather controller itself is not high.


    However, Chen Xin is not satisfied with this, but the people who make video calls with him are already very satisfied with it.


    "Academician Chen, you are too anxious." The person in the video laughingly comforted Chen Xin, and then said to him with a smile: "to do research, we have to do it step by step. How can we become a fat man with one mouthful?


    This weather controller can have the present appearance, already let a person very satisfied! It''s like a child. You have to give it time to grow up! It''s impossible to say that the child born yesterday will run all over the ground today!


    We all know that you want to use the weather controller to change the current situation of the blue star, but it takes time. It''s urgent


    Hearing this, Chen Xin sighed and said, "maybe you are right. I''m really impatient."


    "It''s normal for young people to be impatient. After spending so long in Lucia, I believe academician Chen has accumulated a lot of pressure. Let''s take a vacation and have a good rest." It seems that the person in the video doesn''t want Chen Xin to be so tired that he persuades him to take a holiday: "you haven''t been with your family for a long time, have you?"


    Referring to his family, Chen Xin couldn''t help laughing bitterly and said: "I haven''t been home for half a year, so I guess my mother will be worried to death."


    "Ha ha, so give yourself a holiday and spend time with your family when you come back." The people in the video said to Chen Xin with a smile, even jokingly: "academician Chen, although you are very good, you can finish everything by yourself, but you always have to give others a chance! Don''t do everything by yourself, let others have a chance to show their face! "


    "Good leader, I know what to do." See each other''s words have said this, Chen Xin also can only smile to promise to come down.


    Indeed, he had been in Lucia for so long that it was time for him to go back and spend time with his family.


    Especially their parents, they are very old, and they have already reached the age of life. If it wasn''t for this disaster, maybe they would be enjoying their grandchildren every day, right?


    Thinking of this, Chen Xin can''t help thinking about whether it''s time to think about getting married and having children.


    It''s just that although there are two candidates, it''s not easy for Chen Xin to choose who. After serious consideration, he still finds it difficult to make a choice.


    Hang up the call with the leader, Chen Xin left the communication room.


    At this time, they are close to the border of Yan state. The previous experiment was not conducted in Yan state. Chen Xin worried that there would be some problems, so the experiment was actually completed in Lucia.


    The test area is a no man''s land even before the disaster, even if there are any accidents and problems, it will not cause much impact.


    Coming to the ship island on the top deck, it''s a little bigger than the previous ship Island, and its vision has become more open.


    Just looking in front of the mobile base, you can only see the huge obstacle sweeper and the snow raised by the obstacle sweeper when clearing the road.


    "How far are we from the border?" Chen xinlai goes to the captain who is looking at the map and asks him.


    "The straight-line distance is about 50 kilometers. At our current speed, if there is no accident, we should be able to cross the border tonight." The captain reports to Chen Xin and points out their current position on the map.


    "It looks very close. I wish I could go home early!" Chen Xin can''t help sighing that although the distance between the two fingers is only a little on the map, it actually takes more than half a day to run at the speed of the mobile base.


    After all, the mobile base is so large that it has high requirements for the terrain it passes through. It is difficult to pass through any big pit on the road.


    If it wasn''t for the thick snow all over the place now, and relying on the obstacle remover to flatten the snow directly and make a hard road, it would be possible for such a large mobile base to move forward and move only in a very flat plain terrain.


    The road they are going to cross into the border of Yanguo is a valley sandwiched between two mountains. Even if there is snow on the uneven ground, the slope here is still very large, which puts a huge test on the traffic capacity of the mobile base.


    What awesome is that the mobile base moving mechanism after upgrading is still very powerful. And the huge obstacle removable device in front of the car body can also smooth out a smooth road for the mobile base, so that the mobile base has no impassable obstacles.


    They also passed the final road smoothly, crossed the border and returned to the territory of Yanguo a little later than expected.

 Chapter 586

    Across the border, although the domestic environment is not much better than that of Lucia, the cities and settlements along the way are much denser than that of Lucia.


    Compared with the thousands of kilometers of no man''s land in Lucia, even in Xinjiang Province, it is very difficult to encounter a similar situation. Although the population density is also small, cities or inhabited settlements can still be encountered every few hundred kilometers.


    These settlements are also in good condition. Although they are tens or hundreds of kilometers away from the main cities, there are no problems with the shelters here. They are in place in terms of cold protection and warmth, material supply and even medical security.


    This makes Chen Xin, who has just returned from Lucia, deeply feel the most intense contrast and contrast between the two countries.


    In Lucia, even in cities like their capital, after several riots, shelters have become dilapidated, supplies are in trouble, and health care is overwhelmed by disease. It''s a pretty miserable scene.


    But in the territory of Yanguo, even if it is just an ordinary settlement in Xinjiang Province, there is only a shelter for more than 5000 people, and its situation is much better.


    The strong shelter provides a solid and reliable shelter for all residents, and they can completely resist the invasion of the external extremely cold climate.


    The traditional Karez has been transformed into underground water network and heating pipeline, which provides sufficient water and geothermal resources for the refuge. It provides heating for the refuge and geothermal power generation at the same time, so that the refuge has abundant electric energy, and there is no need to worry about the energy problem.


    The greenhouse also built with containers provides the shelter with a continuous supply of fresh vegetables and other food. Even if the material supply is interrupted for a while and a half, there will be no food shortage here.


    Although the main food source here is the transportation team sent by the city every other period of time, the supply is not very stable due to the impact of today''s environment, but on the whole, there are at least two transportation cycles of grain reserves here.


    That is to say, even if the transportation team is delayed by environmental impact, they can at least persist until the next transportation cycle without falling into the state of broken grain area.


    With such a guarantee, it may not be safe, but at least in Chen Xin''s view, it has done the best it can.


    However, looking at the environment here, a kind of application mode of mobile base suddenly appeared in his mind, that is, as a transport vehicle, it goes back and forth between the city and these settlements, transports materials for each settlement, and undertakes possible rescue tasks.


    The size of mobile base is huge, and it will not be easily affected by environmental factors. Even in bad weather such as snowstorm, this giant of more than 100 tons can fully guarantee its own stability. With the nearly sustainable energy guarantee inside, it will become the most suitable means of transportation as long as it is slightly modified.


    Especially with the helicopter and vehicle, it can achieve effective and rapid support, which is absolutely the ideal choice for regional support in today''s environment.


    Chen Xin thought this way, and felt that he had fallen into a misunderstanding before.


    Mobile base doesn''t have to be used for military use. It also has great potential for civilian use.


    Thinking of this, Chen Xin thinks that he may be able to redesign the existing mobile base and add a transportation type civil mobile base in addition to the medical mobile base.


    At present, the mobile base has not been put into mass production. There are only two prototypes Chen Xin brought back from Siberia.


    One of them stayed in the Research Center for disassembly research and mapping after it was brought back last time, so as to provide data support for subsequent production. The other one is the one that Chen Xin has transformed into a weather controller carrying platform.


    Although Chen Xin originally designed the mobile base for battlefield support and medical mobile base, both of them just stay on the drawings. For the country, although these two mobile bases look good, there is no urgent need at present.


    But compared with these two models, the transportation mobile base is different.


    Although Chen Xin has made isotope batteries and energy towers for a long time, and the country is also vigorously promoting their application, so far, many parts of the country still retain the old way of energy supply and traditional fuel vehicles.


    The way of energy supply is not mentioned. In this regard, the country has been vigorously reforming, but the capacity of isotope batteries is not rich enough to be used everywhere.


    Therefore, the traditional thermal power plants still exist, and even play an important role in many areas.


    This is especially true for vehicles. Although there are new energy vehicles powered by isotope batteries, the production and transformation of such vehicles are relatively troublesome.


    Not everyone, like Chen Xin, can complete the transformation of a car as soon as his eyes are closed. The traditional fuel vehicles still have a considerable number and play their role in many posts.


    But the size and high energy consumption of fuel vehicles determine that they are not the most suitable choice in today''s environment.


    In Xinjiang, a relatively flat Province, the transportation capacity of a mobile base is even equal to that of a hundred trucks, not to mention its self-supporting capacity, which is far less than that of fuel vehicles that need refueling.


    If we can build a transportation network with mobile base as the core, it will be a huge good news for the current material supply.


    As for the fact that the moving speed of the mobile base is not fast, this is an objective problem, but even so, the mobile base can move a distance of one or two hundred kilometers a day. As a means of transportation and supply, as long as the stable supply frequency is maintained, the speed is not very important.


    After clarifying these factors, Chen Xin''s idea of building a material supply network with mobile base as the core has gradually taken shape.


    "It seems that after going back, we should speed up the mass production and construction of the mobile base." Although Chen Xin has no idea whether the plan will be passed by the senior management, it is right to do the relevant work well first.


    It''s impossible to say that when the senior management has passed the new plan, the mobile base is only a draft on the drawing, and even can''t do mass production, then it''s really blind.


    However, mobile base is nothing else. It is not easy to mass produce this kind of thing which is basically the same as amphibious attack ship or light aircraft carrier. Even if the industrial strength of the country was already inflamed before the disaster, mass production is not so easy.

 Chapter 587

    "Transport mobile base? That''s a good idea


    He is still the leader who had a video call with Chen Xin last time, but this time Chen Xin has returned to the research center and is talking to the leader with the help of the communication equipment of the research center.


    Facing the attitude of the leader, Chen Xin naturally felt that the plan was more likely to pass. So he launched the nano molecules on his hand, projected the transportation mobile base he designed these days, and elaborated his whole plan to the leader in detail.


    "This is the transport mobile base I designed. Compared with the previous model, I have made some adjustments to its internal structure." Chen Xin showed his design to the leaders, and highlighted some of the reconstructed parts to explain: "the original vehicle garage at the bottom will be retained, but a lift will be installed here to facilitate the transportation and loading of materials, and the second deck connected by the lift will be transformed into a large warehouse for storing materials."


    Since it is a transportation mobile base, there must be space for loading goods.


    When Chen Xin designed the transportation mobile base, he naturally took this into consideration. He lengthened the length of the original mobile base, and moved the power cabin, which was responsible for the function, backward to the stern of the hull, between the bottom deck and the second deck.


    Then move the personnel cabin and other living facilities to the top deck. In this way, the whole second deck will be empty, which can be used as a cargo hold comparable to a warehouse.


    In terms of personnel allocation, the transportation type mobile base is not as much as the battlefield support type and medical type. The corresponding personnel cabin can naturally reduce some space. After moving to the top deck, it can still be arranged, even if it takes up more than half of the space in the hangar.


    It took Chen Xin a few days and optimized the drawing with the system upgrade. There are no loopholes or problems in this scheme.


    "Because it is a transport type, the vehicles carried should also be adjusted accordingly. I adjusted the original all terrain vehicle to a newly designed vehicle, while the four helicopters with different functions carried in the hangar were reduced to one transport helicopter." Chen Xin continued to explain his adjustment of mobile base to leaders.


    Listening to Chen Xin''s explanation and looking at the demonstration animation projected by nano molecules, the leader nodded with satisfaction.


    But the leader nodded, frowned and said: "although it looks really good, according to academician Chen''s design, this mobile base should be more than 100 meters long, right? Can we build such a big thing? Is it necessary to build it? "


    The leader''s question seemed to press the pause button, which made Chen Xin, who was originally in high spirits, stop explaining.


    Whether it can be built, how much resources it will cost, whether the country can afford to invest such resources, whether the final result is proportional to the resources invested, and whether such a large investment is necessary


    Although these problems do not seem to have much to do with the mobile base itself, they are the key to restricting Chen Xin''s plan and putting the mobile base into practice.


    Is mobile base useful? Of course it works.


    Is mobile base easy to use? Of course it works.


    But is it necessary to build a mobile base?


    Not necessarily.


    Mobile base is not something that has to be built. In the current domestic situation, having a mobile base will certainly make the situation better, but not making it worse.


    So it''s not necessary to build a mobile base, especially when the cost of building it is not cheap.


    This is just like the situation faced by the suvians when they built the land cruiser, the predecessor of the mobile base.


    Does it work? Useful, but not so useful.


    And it''s too expensive. With this investment, it''s better to build more than 180 tanks and make up an armored division to do the same thing.


    That''s why the suvians sealed up three land cruisers in those days, because they were so chicken.


    The current situation of Yanguo is not so bad. After Chen Xin''s adjustment and upgrading, the mobile base can still be of great use.


    It''s just that the cost is so high that it doesn''t seem so cost-effective.


    After all, Yanguo is also in a precarious state. Although the domestic situation is still optimistic, the overall situation is still grim. The country has not got rid of the various effects brought by the disaster.


    In particular, the previous southwest earthquake was a heavy blow for the state of Yan. Although it didn''t hurt much, it also affected the state of Yan in a short time.


    "I understand what you mean. From the current situation, I think the construction of mobile base is necessary." Chen Xin did not use any rhetoric or exaggeration to persuade the leaders here, but expounded in a practical and realistic manner: "the high investment and high cost of the mobile base itself is indeed its disadvantage, but relatively speaking, the maintenance cost of a transportation mobile base is far lower than the consumption of traditional material transportation in an area.


    In the long run, the investment is worthwhile, and with the successful construction of the mobile base, the return of the investment can be seen soon.


    The only problem is the construction of the mobile base itself, and whether the country can put up enough resources to build the mobile base. "


    "Yes, academician Chen, your analysis is in place. The country is really facing difficulties now. For a while and a half, it will not be able to spend so much money to build mobile bases." The expression on the leader''s face also became somewhat helpless.


    If Yanguo still has the industrial construction capacity before the disaster, he can approve Chen Xin''s plan without considering so much. But now the country''s industrial production capacity is still recovering, and he really can''t carry out such a huge plan.


    According to Chen Xin''s plan, each province will be equipped with a mobile base, and the provinces with larger area will be equipped with more mobile bases according to the actual situation.


    A single mobile base may not be very expensive, and the country can afford it, but more than 30


    This is comparable to the investment of two complete aircraft carrier formations, which is not affordable by the country now.


    As for building one or two first to improve the situation in some areas, this may be a compromise, but it is still not a trivial matter. The impact and the things involved still need careful consideration.


    It''s not easy to decide such a big thing even if the leader who talked with Chen Xin is in a high position. So he thought about it and said to Chen Xin, "academician Chen, you should first improve the design scheme of this transportation mobile base, and make a detailed plan on how to build it and how much investment it will take to build one, We need to have a serious discussion before we can make a decision. "

 Chapter 588

    There are not enough resources to produce mobile base, which is the biggest problem Chen Xin wants to promote his plan.


    It''s like playing construction games. If you want to expand production and construction and upgrade the building level, you need more resources first.


    If you want to get more resources, you can either build more mines or miners in the game, or upgrade mining equipment. In reality, it''s the same.


    It is not that the country does not have enough mines, but the change of the natural environment has led to the fact that many open-pit mines and small mines can no longer be used, and the output of the mines that are still in operation has declined due to the impact of the natural environment, resulting in the country''s inability to obtain sufficient resources for a while.


    Of course, there is more than one way to solve this problem, but among the practical and effective ways, improving mining tools is undoubtedly a good choice.


    The research center where Chen Xin works has related projects in this field.


    "Is this the mining Titan you designed?" Chen Xin looks at the body that is crushing a rock for testing, covers the noise reduction earphone on his head, and shouts to the researcher through the microphone.


    The researcher nodded his head and answered Chen Xin positively: "yes, after our test, human form is not necessary, so we adopted a more reasonable structural design."


    No wonder researchers say that, because the Titan in front of us is obviously different from those designed and manufactured by Chen Xin.


    Four spider like mechanical legs maintain the balance of the body. As for the body itself, it looks like the spider drow in the fantasy adventure game Chen Xin used to play before, an evil creature that saws off the human lower body and puts it into a giant spider with brain removed.


    The driver is wrapped in the upper part of the simple exoskeleton like body, which is not very different from the ordinary exoskeleton. There is nothing special except that the body is bigger and a large air pick is connected to the arm as a mine gun.


    But when it comes to the four legs of the lower body and the mine bucket with the back like the belly of a spider, it really looks like a spider drow.


    However, the shape is not important, because from the structure of this thing, this kind of structure is much more convenient than Chen Xin''s original design of humanoid Titan.


    The stability brought by four legs allows the body to load one more bucket without additional balance design and load, and the traffic capacity brought by four spider legs is not comparable to that of two legs or wheels.


    And for the underground mine, it''s enough to decide to design the mining Titan as a spider.


    In fact, the spider''s shape is really practical. In the obstacle test environment, the spider with four legs runs much faster than the spider with two legs.


    Moreover, the mining efficiency of this mining Titan is also very good. In Chen Xin''s conversation with the researcher, all the rock blocks used for testing have been broken and put into the bucket behind him.


    "It''s a good design, but I remember spiders have eight legs?" Seeing that the test had been finished, Chen Xin took off his headphones and joked with the researchers.


    Like Chen Xin, the researcher also took off the earphone. At this time, when he heard him say this, he laughed a little embarrassed. Then he explained to Chen Xin, "in fact, we built an eight legged Titan at the beginning. The prototype is much more efficient and has better traffic capacity than the current one. When we tested it, it can even walk on the wall, The mining efficiency is more than twice that of the current one.


    Not only that, it can also provide good protection for the driver. Even in the outdoor, the good sealing structure can resist the cold, and can resist the collapse or splash of gravel. "


    In fact, the four legged mining Titan is hardly a real Titan.


    Although the volume is not very different from that of the Titan made by Chen Xin before, considering that there is still a bucket on the mining type, which accounts for one third of the body volume, how small its body volume is can be imagined.


    The lower part of the body and the mine bucket are not equipped with armor and cover. It looks like they are all exposed, while the upper part of the body is more like a set of exoskeletons are removed and connected directly. There is no real Titan cockpit that can fully accommodate the package of the pilot.


    This is not so much a Titan as an enhanced exoskeleton.


    It''s just that compared with the exoskeleton, the power performance and power output of this mining model are much larger. It''s beyond the category of exoskeleton and can be listed as Titan.


    Although it''s only a beggar''s version of Titan.


    When Chen Xin came to the warehouse with the researcher, he saw the prototype he mentioned.


    Eight slender supporting feet stand on the floor, supporting a slightly slender upper body compared with the normal Titan. Four mechanical arms are connected with four air picks, and a pair of big Ao is installed on the lower body just like a real spider, which can swallow the broken ore directly into the "belly", a fully covered mine cabin hanging behind.


    If the Eight Legged Titan in front of us is described as the SR character in the card drawing game, the four legged Titan outside can only be regarded as n-card dog food compared with it.


    "Wow, this guy''s design aesthetic is great! If you add a little more feminine design, you can cheat krypton in mobile games. " Chen Xin saw a joke, went to the Titan, patted one of the supporting feet, full of praise for it.


    However, he did not ask the researcher why he did not continue to study this one, but to build the four legged n-card outside.


    Because the reason is obvious. It''s like drawing cards in the game, and Sr characters need krypton gold to get them. This Eight Legged Titan is obviously more expensive than the four legged Titan outside.


    Trying to open the cockpit, Chen Xin sat in and felt the feeling of riding. Then he asked the researcher standing aside, "how many four legged ones can you build for this model?"


    Although Chen Xin doesn''t manufacture a specific cost, he can also estimate that if such a standard Titan is to be manufactured without his participation, the cost will be quite high, and the cost of the simplified four legged version may not be as expensive as the cockpit he is sitting in.


    "One standard Titan can make five mining models." The researchers came up with the reason why they gave up mass production of standard Titan.

 Chapter 589

    How about the standard Titan? Of course!


    Before the earthquake relief in Southwest China, Titan''s excellent performance has proved the excellence of this large humanoid mechanical vehicle.


    They are robust, flexible and convenient, and can adapt to various positions and environments almost as well as people.


    And all kinds of Titans can be used in almost most occasions, whether military or civil, with high value.


    That''s why even if the standard Titan is expensive, the state still plans to mass produce it.


    But it''s not cheap.


    The cost of a standard Titan, no matter how simple it is, is almost the same as that of the latest fighter before the disaster. Before the disaster, the country did not need the money. However, in the current environment, it can only be said to build a batch of small-scale fighters first.


    Large scale production of Titans, which for the country, really can not afford.


    Even if Chen Xin reduced the cost to the price of a main battle tank, it could not be mass produced.


    This is why although Chen Xin has provided a large number of high-tech and good things to the country, the country still changes and reuses the old things.


    Is not willing to use good things, but really can not afford to use.


    Therefore, in the mining Titan project, the design team adheres to only one basic principle, that is, cheap, mass production.


    The buffer cockpit, which can completely wrap the pilot, has been removed and replaced with a helmet and metal frame with only exoskeleton for protection.


    The driving mode has also been transformed from the human-computer interaction assisted by the computer intelligent program into the force feedback operation of a more fool.


    Just these two changes have downgraded the mining Titan from a standard Titan to a mechanical frame that is only a little better than the exoskeleton.


    Of course, the original high cost will come down.


    Titan itself is expensive, of course, and its driving mode has a lot to do with it.


    It''s a metal structure that weighs several tons. Even if there are all kinds of power assisted machines inside to make the giant move, it''s not something that can be pulled manually by the driver.


    It''s just like the joystick of an airplane. The old airplane is connected with the wing by steel wire. In those days, the pilot used to pull the airplane by brute force. So the scene of the broken joystick in the cartoon is not a fake. Sometimes it''s broken and it doesn''t have to be pulled.


    The control lever of modern aircraft has hydraulic power or electronic assistance. The larger the aircraft, the more complex it is, and the higher the cost will be.


    Titan is the same. If we want to make this kind of several ton people move, we need to write a complex control program, so that the computer installed in the cockpit can accurately recognize the driver''s instructions and give timely feedback. This not only requires a lot of labor, but also needs to design a very complex operating system.


    Not the one in the computer, but the system that operates Titan.


    This is the big part of the cost. After all, electronic components, circuits, mechanical transmission structures and other things are money.


    But it''s easy to switch to the exoskeleton type. A few metal hydraulic connecting rods, a set of force sensing feedback module, all live together.


    Compared with the standard Titan, the combined cost of a mining Titan is less expensive than that of a standard Titan cockpit.


    But that''s also its advantage.


    This thing is designed to improve the mining efficiency of the mine, that is to say, the miners can extract more ore in unit time.


    That Eight Legged mining Titan prototype is really efficient. One can work twice as efficiently as the final mining Titan, but this is based on the premise of five times the manufacturing cost and the need for professional Titan drivers.


    Although professional Titan pilots have been trained all the time, and even a training base has been built near the scientific research center, there are not many of them, just a little more than the total number of Titans produced at present.


    Under such circumstances, it is obviously impossible for the valuable Titan pilot to do the work of mining.


    The optimal solution should be to allocate the mining Titan to the basic level miners directly to improve their work efficiency.


    So it''s easy to understand why the mining Titan did such a good job.


    However, Chen Xin is not very satisfied with this. It''s not that he is dissatisfied with the design idea of mining Titan, but that he thinks it can be improved.


    The researcher asked for a mining Titan that was being tested. He sat on it and tried to operate it. He also compared it with the prototype that he had sat on before.


    It has to be said that the contrast is really strong. The comfort of driving is really different.


    Of course, on the whole, the mining Titan is OK, although the cab... No, it can only be called the driver''s seat. The driver is completely exposed, which can not be called a "cab".


    Although the driver''s seat is not comfortable enough and completely exposed, considering that the miners'' working environment is hundreds of meters underground, this simple design is not a big problem. Even if it is used in an open-pit mine, as long as the workers wear protective clothing, there will be no problem.


    The simple exoskeleton is also easy to operate, only need one or two days of training to be able to fully master its use.


    But for the mining efficiency of this thing, Chen Xin thinks it can be improved.


    There is only one air pick. The efficiency is not substantially improved compared with the original manpower exploitation.


    "Contact the mining department and ask them to arrange a mine. We need to take this mining Titan to the site for testing. I always feel that it can be improved." Chen Xin came down from the mining Titan and said to the researcher on one side.


    However, after listening to his words, the researcher on one side asked curiously, "academician, what do you think can be transformed? Now this should be the most appropriate way, right? That''s what we''ve simplified according to the lowest manufacturing cost. "


    "No, no, what I''m going to do is not to simplify its manufacturing costs, but to enhance its efficiency." Chen Xin shakes his head and shakes his head. He is afraid that the mining Titan explained to the researcher, "your simplification is very good. Its cost is effectively reduced, but the mining efficiency is also reduced, isn''t it? Although it is right and necessary to reduce the cost, if the efficiency is too low, it will lose its practical significance.


    So I''m going to take this mining Titan to the mine for field test to see how efficient it is and whether there is room for improvement. "

 Chapter 590

    Chen Xin went to a ilmenite mine in the city.


    This is a mineral deposit that was proved in the municipal area, but was not mined before the disaster.


    However, with the great demand for rare metals in the process of domestic industrial reconstruction after the disaster, especially after the establishment of Chen Xin''s scientific research center, the proven and not too difficult mines like this have been arranged for mining.


    "At present, the mine is not deep, only more than 300 meters, and the overall mining difficulty is relatively small." A mine technician is explaining the situation of the mine to Chen Xin, but he is a little nervous in front of Chen Xin: "however, because it is a mountain mine, and the mining time here is very short, and the construction is insufficient, so at present we mainly use manual mining method to mine ore, so the output does not reach the maximum allowable mining amount of this mine."


    Chen Xin noticed the other party''s nervousness, but he didn''t say much. He just asked the technician, "what equipment do the underground workers mainly use?"


    "This is mainly the protective equipment that the state requires to wear when going down the well. In the past, some exoskeletons were distributed to the workers in order to increase production, but now they are also distributed to the workers." When Chen Xin asked about the underground situation, the technician became more nervous, but he still answered his question seriously.


    Hearing the technician''s reply, Chen Xin nodded and said with some approval: "exoskeleton is very practical for this kind of work which is engaged in heavy physical labor. How many sets have you distributed here?"


    The technician saw that Chen Xin didn''t seem to have any expression because of what he said. Instead, he calmed down a little and said to Chen Xin, "well, we have a small mine here. We don''t have many exoskeletons. We can''t do a single piece of work, so we can only allocate it to the workers at the bottom of the mine. Their workload is bigger and they need more."


    Chen Xin nodded slightly, and he knew more or less about the situation of the mine.


    Before the disaster, when he was just an ordinary person, when their survival group discussed how to avoid the doomsday, in addition to buying air raid shelters and building self built shelters, some people also put forward the idea of using abandoned mines to transform shelters.


    However, this idea is very impractical and unsafe.


    First of all, it''s very troublesome to buy a mine in Yanguo, even if it''s just an abandoned mine. Although it''s much simpler than buying an air raid shelter, it''s still a matter of going through a lot of procedures and approving qualifications.


    This is not very realistic for the people in the survival group at that time, because what we want is a plan that can be implemented immediately, rather than the troublesome things that will take several months to go through the formalities.


    In particular, when it was still the end of the day, the relevant departments were still working or not.


    And for the mine transformation itself, it is not without problems.


    If it''s a mine that hasn''t been mined out, it''s a good thing to say that the underground space with solid support can really be used as a refuge or to accommodate large machinery and equipment.


    In fact, at the beginning of the disaster, the country did use some mines to protect valuable industrial equipment and other important materials.


    But for abandoned mines, it''s less safe.


    The geological structure destroyed by mining, the long-term unattended and permeable, decayed and collapsed tunnel


    All of these constitute a rather fatal potential threat, not to mention a series of problems such as air circulation inside the mine.


    Although the reasonable transformation can indeed make the abandoned mine tunnel into usable or even living space, it is too long in terms of cost and cycle, which can not be afforded by Chen Xin and others at that time.


    In his mind, Chen Xin shook his head slightly. These things were all the attempts they made to survive. Now they have little meaning, leaving only some memories and related knowledge.


    Recalling the memory that he needed, Chen Xin clearly knew that in a mine, he would continue to dig down, and excavate several working faces at different depths at the same time, so as to increase the total mining amount per unit time.


    In this process, the workers at the bottom of the mine are undoubtedly the hardest, because they have to dig down. In terms of workload, they have to work harder than the workers at other working faces.


    Recalling this, Chen Xin looked at the researcher who was with him and asked him, "how are you preparing for the mining Titan?"


    "The prototype and simplified machine have been debugged and can be put into use at any time for testing." The researcher enthusiastically replied to Chen Xin, and he was also looking forward to the performance of the two mining Titans designed by him when they were put into practical application.


    Chen Xin nodded slightly and asked the technician, "we are going to use your mine to test new industrial equipment. We have been informed before. Is the test site ready?"


    "It''s ready. Are you going to test it now?" The technician asked, but his eyes involuntarily turned to the two titans that were starting up behind the three.


    "Well, now that we''re ready, let''s start testing." Chen Xinru nodded and said to the researcher.


    When the researcher heard Chen Xin say this, he immediately responded and said to the two mining Titans behind him, one large and one small, which had already started: "the experiment begins! Mining Titan prototype, simplified machine, field mining test, start


    With the researcher''s voice, the two titans moved.


    "That... I''m sorry! Can you wait a moment? " Seeing that both Titans were moving, the technician of the mine suddenly said to Chen Xin, "that small robot can take our elevator down, but that big one... It should weigh several tons, right? The personnel lift can''t bear such heavy things, so it can only be transported by the tramcar. "


    Hearing this, Chen Xin didn''t feel surprised. He just winked at the researcher.


    The researcher understood and took the technician of the mine to one side. After asking him about the situation in detail, he made the adjustment.


    The smaller simplified machine will ride the personnel elevator with them to the bottom of the mine, while the prototype machine will go down to the working face of the mine through the ore transport channel, and then go down to the bottom of the mine relying on its own mobile ability.

 Chapter 591

    In the deepest part of the mine, there are only a few light bulbs for lighting, providing limited light sources.


    Damp, sultry, stuffy, noisy, dark... All kinds of bad adjectives that can be thought of come out in Chen Xin''s mind.


    It''s not that Chen Xin deliberately belittled it. It''s that the mine is hundreds of meters underground, which is really such a bad thing.


    Because of the deep underground and the lack of air circulation, even before the disaster, the temperature is higher than that of the ground, and even deeper, the higher the temperature.


    That''s why in the past, when miners were less aware of safety, these people were more used to working naked.


    If it''s a traditional mine pick, it''s OK. At most, it makes a jingling sound. But most modern mines use air picks, which make a lot of noise.


    Working in such an environment, you can imagine how hard it is to work.


    But for the miners working here, they feel lucky to have such a job.


    In the current environment, it is very happy to have a stable job and get enough quota supply to support a family every month.


    And their working conditions have improved a lot.


    The newly issued protective clothing can effectively isolate the hot and humid environment under the ground, while the exoskeleton makes the work that originally required a lot of physical strength easier. On the whole, the miners are very satisfied with the current situation.


    It is for these reasons, even in the bottom of the mine to do the most dangerous and arduous work, these workers are still trying to complete the work in their hands.


    But today, their work needs to be suspended.


    After receiving the instructions from the technician, the workers stopped their work one after another, and looked blankly at the technician and Chen Xin, who was standing with him.


    They don''t quite understand why they have to stop all of a sudden.


    "Zhao Gong, what''s the matter?" Among the workers, the foreman found the technician and asked him about the specific situation: "our schedule is very tight now. The shutdown will delay the progress."


    "The top sent someone to test some things. You don''t have to worry about the delay of work stoppage." The technician didn''t explain more to let the other party understand that it would not affect their work, so he turned to Chen Xin and said, "it''s ready to start the test."


    Chen Xin nodded and motioned the researcher to start the test.


    After receiving the instructions from Chen Xin, the researcher signaled the simplified version of mining Titan to come forward and prepare to start the test.


    Seeing the appearance of the mining Titan, the workers were shocked, and were obviously shocked by the strange shape of this thing.


    But the researcher obviously didn''t care what the workers were thinking. He just directed the pilot to drive the Titan to the place where the workers were working just now. The four supporting feet opened and stood firmly in front of a rock wall.


    Then he raised his pick.


    Seeing this strange looking machine in front of them, which looks like a big spider, they started to hit the rock wall with an air pick at the place where they just worked. The workers had some reaction and guessed that it might be a mining machine.


    This makes the workers who see the mining Titan a little excited. Obviously, they are very curious about the new machine. They are still wondering whether they can use the new thing and what the parts of it are for.


    But the foreman was not as curious as the workers. Looking at the work of the machine, he immediately frowned, went to the researcher who was conducting the test and said to him, "you are not playing right! The position of the air pick is particular. It''s very inefficient for you to fight like this, and it will destroy the part we have already played before! "


    "What did you say?" Because of the noise of the pickaxe, some researchers didn''t hear what the foreman said.


    The foreman could only repeat his words aloud. This time, not only the researcher, but also the technician and Chen Xin heard his words.


    After listening to the foreman''s words, the researcher took a look at the position where the driver who was operating the mining Titan hit the air pick, which was indeed different from the position where the workers had hit before. After hesitation, he looked at Chen Xin and asked him, "academician, what should I do?"


    When the researcher asked Chen Xin for instructions, the driver of the mining Titan also noticed the movement here and stopped his action.


    In the face of this situation, Chen Xin went to the foreman with great interest, looked at him up and down, pointed to the mining Titan and asked, "you said he was playing in the wrong position?"


    "No, if the air pick wants to break the rock wall, it has to pay attention to the location of the hole. If the hole is well drilled, the stone will split itself. If the hole is not well drilled, it''s just a hole." The foreman nodded his head seriously. He didn''t dare to say anything because Chen Xin looked like a big man.


    Hearing the foreman''s affirmative reply, Chen Xin nodded slightly, looked at the mining Titan in front of him, then looked at the foreman, thought about it, and asked him, "let''s go. Are you better than him?"


    "I can!" The foreman''s eyes brightened. He was very confident in his work and professional field, but he hesitated: "I can''t use the thing he opened."


    "It doesn''t matter. Let him teach you." Chen Xin said, turned his head to one side of the technician, asked him: "borrow your workers, no problem?"


    "Of course, it''s no problem, but do you really want him on? This should be very expensive experimental equipment, right? What if it''s broken? " The technician still maintained the foreman. Although he agreed to let him go, he also pointed out the possible problems.


    Chen Xin didn''t care. He asked the foreman, "can you use an exoskeleton?"


    "Yes! It''s not long since it was newly distributed, but we''ve all learned to use it. " The foreman touched the exoskeleton he was wearing and gave Chen Xin a positive answer.


    Hearing the foreman say so, Chen Xin made a decision: "let the driver change with him, teach him how to use this simplified version of Titan, and then let him test it."


    After that, it seems to be to prevent researchers from objecting. Chen Xin added: "it is the labor tools originally designed for these workers to test by themselves that can reflect the most intuitive results."


    "All right, academician!" The researcher did not raise any objection. He quickly nodded and motioned to the driver to exchange with the foreman.


    The driver was a little confused, but after the researcher explained it, he didn''t make any trouble. He was just a test driver of Titan, not a professional miner. It''s normal that he is not as proficient in mining as others.


    So he directly exchanged with the foreman and enthusiastically instructed him how to operate the simplified mining Titan.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 592

    The foreman is really better at using the air pick than the previous drivers. After understanding how to operate the mining Titan, he quickly uses the air pick equipped on the mining Titan to continue their interrupted work on the rock wall in front of them, and soon breaks a rock wall into pieces.


    Just when the foreman was going to clean up the mined ore as usual, he found that the set of equipment on his body limited his movement, and he was frozen there for a moment.


    "You can pick up the ore and put it in the bucket at the back." The researcher thought he didn''t know where to put the ore, so he gave a warning.


    But Chen Xin patted him and said, "he can''t bend down and pick up the ore on the ground."


    Being reminded by Chen Xin, the researcher immediately came to the foreman and took a look at his equipment. Then he said: "he was wearing ordinary protective clothing. The life support equipment on his back and the structure of the simplification machine supported him, so he couldn''t bend down. In the original design, he could squat down to pick up ores."


    For this explanation, Chen Xin nodded understandably. It''s not strange. After all, it''s Titan. Even if it''s a simplified version, it''s very easy to carry a set of life support equipment on it.


    However, this kind of design is not practical in Chen Xin''s view, because the protective clothing itself has life support equipment. It is unnecessary to redesign new protective clothing in order to drive Titan.


    As for how this is designed now... Titan drivers are not wearing protective clothing, but Titan''s driving clothing. Their life support equipment is different from the structure of ordinary protective clothing.


    This kind of problem is quite common in design, because when researchers first design something, they first consider to achieve the core goal and solve the problems, and then they improve on the basis of achieving the core goal and add other design goals.


    Before finalization, everything can be modified, which is the purpose of testing.


    Find out the inadequacies or irrationalities and revise them.


    However, with the help of researchers and Titan drivers, the foreman unfastened the fixed connection and came down from the mining Titan. With a frown, Chen Xin came to the simplified version of Titan and motioned several people to get out of the way. He picked up a large ore on the ground and put it into the bucket. Then he asked the foreman, "how many times do you have to repeat this kind of work a day?"


    "We haven''t counted that. There are always dozens of times a day. It has something to do with the hardness of the rock wall and the efficiency of our work." The foreman was a little stiff in front of Chen Xin.


    Chen Xin nodded, looked at the researcher and asked him, "I saw that there was a Da''ao auxiliary loading and unloading ore on the prototype machine before. Why did the design be removed from the simplified machine?"


    "This..." the researcher was stunned by Chen Xinwen. After a long time, he explained: "the design is not very stable, and the operation is a little complicated. It''s not very convenient. Considering the cost, he canceled the design in the simplified version and changed it to what it is now."


    Hearing what the researcher said, Chen Xin shook his head helplessly and said to him, "although it''s important to simplify the structure and reduce the cost, you''ve overdone it! No matter how complicated the design is, it''s easier than bending over and picking up stones like this? "


    "Ah, it''s... We''re not thoughtful." Although he didn''t change the design, the researcher had to carry the pot.


    In fact, in the previous laboratory testing phase, the mining Titan initially retained an auxiliary mechanical arm to collect ore, and then loaded it directly into the back hopper.


    However, because it is a hopper, not a bunker used on the standard Titan, there are some differences in the structure between the two, which leads to the ore in the hopper will slide out from the hopper when the simplification machine lowers and uses two mechanical arms to collect ore.


    Although it is said that adding a partition can solve the problem, in order to simplify the design, and in the actual test, the driver bent down to pick up the stone and didn''t find it inconvenient, so the relatively complex design of the mechanical arm was removed.


    However, after listening to Chen Xin''s words, the researcher also reflected that he was thinking badly.


    During the experimental test, they just broke a simulated stone poured out of cement. Even after breaking it with an air pick, it just broke into several pieces. It was really easy to pick up the strength of the exoskeleton. It was just a matter of bending down.


    But for the workers under the mine, it means that they have to bend dozens or even hundreds of times a day.


    The equipment originally designed to improve the production efficiency and reduce the labor intensity of workers increases the degree of fatigue of workers, which is undoubtedly undesirable.


    So after Chen Xin pointed out this point, the researcher soon realized this problem, so he took the initiative to carry the pot.


    However, it''s not for the sake of perfunctory. The researcher quickly asked Chen Xin, "academician, do you think the original design of the manipulator should be added back?"


    "I don''t have a say in this. I have to ask this worker." Chen Xin pointed to the foreman standing in front of him and said to the researcher, "whether it''s easy to use or not depends on the actual users who have used it before they can give the most intuitive answer. Is it necessary to change the structure of mechanical arm to assist in ore collection, or let him see what''s going on?"


    "OK, I see." The researcher nodded, didn''t say anything more, just looked at the passage where the crowd came just behind him, waiting for the arrival of the prototype.


    But after waiting for a long time, the prototype didn''t come down. Instead, the driver himself came down from the elevator.


    "Sorry, academician! The prototype is too big. It got stuck when it came down. " The driver of the prototype plane was helpless and depressed. He finally got a chance to drive Titan, but he got stuck because of his size. It was a shame.


    When Chen Xin heard this, he was surprised and asked, "how did it get stuck? Where did it get stuck? "


    "In the tunnel above, I came in very smoothly and didn''t encounter any obstacles, but the tunnel below suddenly narrowed and jammed the body." The driver was also aggrieved when he said that.


    Originally, it was just a test, and the previous passage passed smoothly, so he was careless. Unexpectedly, because the light was too dim, he didn''t notice that the tunnel in front of him suddenly narrowed, so he was stuck in the tunnel wall.

 Chapter 593

    Finally, with the help of the simplified machine and several miners equipped with exoskeletons, the stuck Titan finally got out of the difficulty and the test was carried out smoothly again.


    But this time it was the pilot, not the miner, who drove the prototype Titan.


    After all, it''s a real Titan. You have to accept professional training to drive it. It''s not something ordinary miners can play with.


    Seeing the real Titan''s mining efficiency, both miners and technicians praise this kind of large-scale machine. In particular, seeing that Titan can continue to crush the rock wall, and at the same time, it can use the two mechanical big Ao in its lower abdomen to continuously stuff the ore into the mine cabin behind its belly, which makes their eyes even brighter.


    Although the development of modern science and technology has separated the industrial and mining industry from the primitive and heavy manual labor, under the current environment, the mine still adopts the relatively primitive manual labor mode.


    Workers use pickaxes to destroy the structure of the rock wall, so that it is broken into ore, and then manually load the ore to the mine car, and then transport it from the ground to the ground.


    It''s not that the mines don''t want to use new technology, but they really don''t have the money to purchase new mining equipment. Although the country is also vigorously organizing production, this kind of thing is always in short supply. When the factory produces it, it''s also important for the big mines to use it first. Such small mines with small mining volume can only rely on pneumatic picks and manpower.


    There is no other advantage, the only one is the low cost of labor and cheap equipment.


    But this does not mean that people in the mine do not want to have good labor tools to improve their labor efficiency.


    Just looking at the prototype, although the workers'' eyes were bright, the technicians could only smile bitterly and then gave up the idea of buying this one.


    Of course, he can see that the prototype is good, but he can also see that the prototype is expensive. Even if this kind of valuables are mass produced, they can''t afford it.


    On the contrary, he thinks that the simplified machine he saw below is more likely to be equipped for mining.


    "Master, do you think it''s necessary to use these two big clamps to collect ore?" Chen Xin found the foreman and asked him.


    The foreman looked at the two big AOS under the prototype carefully. Then he nodded to Chen Xin seriously and said, "it''s very necessary. With this, we can drill all the time without stopping to pick up ores."


    Obviously, the foreman is very satisfied with the design which can save a lot of things.


    However, he also understood that the prototype was not something they could care about. After that, he added: "in fact, I think the former one was very good. If I improved the design, it would be great. Although this one is good, it''s too big to be used underground."


    Hearing what the foreman said, Chen Xin took a look at the huge prototype machine in front of him. He thought that it would get stuck in the tunnel just now, so he could hardly disagree with what the foreman said.


    He thought about it seriously, and felt that it was true. The giant Titan was huge, even if the mining type had specially reduced its size.


    Compared with the structure and volume of the simplified machine, which is basically similar to the exoskeleton, and the height and size of the prototype machine, Chen Xin also thinks that the smaller one is more practical in the mine.


    After all, in the narrow mine tunnel, once the mainframe like the prototype is stuck, the effect will be comparable to the mine disaster.


    But the simplification machine is different, the relatively small structure also brings more light weight, so that it can meet the danger will not be too big and delay.


    Therefore, after this field test, Chen Xin has already had an idea for mass production of mining Titan.


    After the test in the mine, Chen Xin and his party returned to the research center.


    The huge prototype machine was naturally driven into the warehouse and was still on standby, but the simplified machine was towed to the laboratory, ready to put the idea into practice immediately.


    The mechanical arm that had been removed was added back, and the ore hopper opened a mine entrance again. It was placed in the middle of the two mechanical arms, which looked like the front face of a crab.


    Seeing this kind of design, Chen Xin didn''t hesitate and hesitated for long, so he killed the design draft.


    At first glance, the original design is added back, which only solves the current problems, but does not solve the previous problems. Otherwise, the design sketch Chen Xin saw will not just copy the original design completely.


    However, although he killed the manuscript, Chen Xin gave his plan.


    "Just design the two arms to turn 180 degrees." Chen Xin directly modified the performance of the design drawings submitted by the researchers, and said: "you don''t need to stick to the mouth at the bottom to insert the ore, and let the mechanical arm flip 180 degrees ¡ã£¬ Just throw it in the bucket! We build industrial machines, and we don''t need to be too innovative or high-tech to make them run smoothly or to solve the problem. "


    Hearing this, the researcher immediately had a feeling of being broadened. At the same time, he also understood Chen Xin''s idea of turning the manipulator 180 degrees ¡ã It is much simpler, more direct and more rude than the idea of opening the door on the bucket, but it also solves the problem that workers need to bend many times every day and the ore in the bucket will slide.


    "Academician, can this be finalized?" Looking at the design that has been changed by Chen Xin, the researcher asks Chen Xin.


    Because Chen Xin''s designs are always ready for mass production, Chen Xin seldom modifies his designs many times, so the researcher asked.


    However, Chen Xin did not answer this question. He just shook his head at him.


    "After modification, make several prototypes, send them to the previous mine, continue testing, and record the feedback of all workers after using them." Chen Xin told the technicians.


    The technicians naturally knew that the prototype needed to be tested, so they didn''t ask any more questions, nodded and took away the drawing.


    Watching the technicians leave, Chen Xin touches his chin and feels that although the prototype can''t be mass produced, it doesn''t mean it''s useless at all.


    Although there are some problems and shortcomings in its design, it is undeniable that this kind of non-human Titan design has opened up a new idea for Chen, and let him have a new idea for Titan design.


    "Let''s take this to practice and transform it! After all, it''s a waste of resources to build things in the warehouse. " Chen Xin waved and projected the structure of the prototype with nano molecules, and began to think about how to modify it.

    "Back? Wash your hands and eat. " Back in the shelter of his own home, the voice of his mother calling him to eat came.


    Chen Xin has a smile on his face. After leaving home for such a long time, it is undoubtedly a great happiness for Chen Xin to be able to eat the food cooked by his mother after working every day.


    At the dining table, his father is setting dishes and chopsticks, and Mo Qingyan and Qin LAN are helping to carry food from the kitchen.


    After all, they are two girlfriends, which was not accepted by the public in the past.


    Although Mo Qingyan and Qin LAN have accepted the current mode of getting along, Chen Xin still feels a little strange, especially when they appear together with her parents.


    It''s like a boy taking his girlfriend home. He''ll feel a little uncomfortable the first time.


    Although Chen Xin has taken his girlfriend home for a long time, it is immoral for him to have two girlfriends. He will worry that his parents will not accept it.


    Fortunately, Chen Xin''s parents didn''t care much about it. Although it was hard to accept that his son had two girlfriends, they didn''t say much.


    In such an environment, it is the greatest happiness for a family to be together. There is no need to worry about other things.


    It is a simple and happy thing for a family to sit around the dining table and eat dishes that are ordinary but full of home flavor, whether before or after the disaster.


    "Son, what have you been up to lately? Didn''t you just come back from abroad? Why are you on a business trip these two days? " Chen Xin''s mother took a look at her son and asked about his work.


    "For work, there''s a device to test." Chen Xin did not explain too much, but simply said what he had done.


    For a mother, as long as she knows what her son is going to do, it''s enough to make herself at ease. She doesn''t need to know too much.


    As for the father on one side, he just told Chen Xin: "work things should be done seriously, don''t be careless, you are a leader now, you should set an example, do you know?"


    "I see, Dad." Chen Xin is accustomed to a sentence, from small to large, not to eat when his father did not less than a variety of advice, Chen Xin listen to have become a habit.


    However, even so, the advice of his parents still has a lot of insight and valuable life experience, and Chen Xin did not show any impatience.


    After dinner, Chen Xin wanted to help wash the dishes, but he was directly driven out of the kitchen.


    Looking at Qin LAN and Mo Qingyan washing dishes in the kitchen, Chen Xin touches his nose and has to turn around to leave and go back to his room.


    Although according to the rules of the family, women cook and men wash dishes, since two girlfriends rush to do the dishes, Chen Xin is willing to save some time.


    I stayed outside for half a year. Although I didn''t suffer much, compared with the comfortable environment carefully built by myself at home, it was still worse than one grade.


    So after returning to his room, Chen Xin lay down on the bed and didn''t want to get up.


    "Hoo hoo, this energy is really not as good as before!" Chen Xin couldn''t help sighing.


    Maybe it''s because I''m getting older. Although I''m only in my thirties and I''ve been back home for several days, the tiredness caused by going out for a long time has not subsided.


    If it was in the past, Chen Xin would not feel so tired. He even had the experience of going to Shanghai stock market on business in the morning, coming back at two or three o''clock in the morning after he was busy, and continuing to work the next day.


    But now the body has long been unable to bear such hard work.


    Thinking of this, Chen Xin can''t help but want to go to a hot spring.


    Although some people say that hot spring can''t really eliminate fatigue, it just makes people feel comfortable physically and feel relaxed in the sense, and fatigue still exists, this doesn''t prevent Chen Xin from hoping to relax himself by taking a bath.


    When he comes to the bathroom and takes off his clothes, Chen Xin immerses himself in the bath.


    Feeling the warm water around him, he couldn''t help taking a long breath.


    It has to be said that the island country across the sea has a special preference for taking a bath. Even if the family is poor, there is a reason why they have to take a bath even if they get a cement pool or an iron bucket to burn firewood.


    This kind of relaxation brought by the whole person soaking in hot water is incomparable to any other way.


    Chen Xin had been away for half a year before. Although he said that there was no shortage of living conditions and he could take a bath at any time if he wanted to, it was impossible to say that he could be provided with the service of taking a bath for him.


    After all, Lucia was already in short supply of heating at that time. In the end, the city''s heating could only be maintained by the energy tower supported by Yanguo. How could there be extra resources to repair the bathhouse and take a bath?


    While taking a bath to get rid of fatigue, Chen Xin can''t help comparing the living standards of people between Lucia and Yanguo.


    As a former superpower, Lucia is in complete decline. Although before the disaster, relying on the iron hand and strength of this generation of leaders, the whole country has gradually come out of the quagmire brought by the disintegration of suvia, the whole country is still full of various problems.


    The arrival of the disaster almost completely destroyed the country.


    This can be deeply felt in the life of the people Chen Xin saw when he arrived at Lucia.


    Although the people''s life in Yanguo was also greatly affected, on the whole, at least there was no food shortage and serious survival problems.


    Although there are also many problems in all aspects, the country has been trying to solve the problems and make the people live better.


    Although there is still a big gap in life before the disaster, at least the people of Yanguo have no worries about food and clothing.


    Not to mention urban riots or mass epidemics.


    As for Lucia... When Chen Xin left, Lucia''s situation in all aspects had improved, the riots in the city had been completely solved, and the heating and food had been guaranteed with the aid of Yanguo, but on the whole, the living standard of the people in Lucia was still very low.


    Such a strong contrast between the gap, let Chen Xin more to live in the country and feel lucky.


    If he is living in Lucia, even if there is a system, he is very sad. In the present life, the most likely thing is to hide in the shelter of his own home, and then calculate everyday, right?


    Instead of living without pressure like now, you can even think about how to end this disaster.

    After a good night''s rest, Chen Xin can finally face the new day with great energy.


    After breakfast in the morning, Chen Xin left his shelter and went to his office in the ecological dome, ready to start today''s work.


    Chen Xin''s office is located on the second floor of the ecological dome, with its back facing the atrium of the dome. Relying on the artificial light from the ceiling, the office does not look dark even if the lights are not turned on.


    Moreover, after opening the window leading to the atrium, the oxygen produced by the plants in the atrium will flow into the office with the specially designed air flow, bringing fresh air to the office.


    Chen Xin likes this office very much, not only because the environment is very good, but also because his exclusive laboratory is next to the office, and the elevator connecting to the downstairs test field is next to it. It''s very convenient for Chen Xin to do whatever he wants to do.


    However, most of the time, Chen Xin did not stay in this office, and this office has been empty for half a year.


    Fortunately, even if no one used it for a long time, Chen Xin''s office was still very clean, and the green plants in one corner of the office grew very well, and did not wither because no one was there for a long time.


    This is naturally the result of someone taking care of it every day. Otherwise, even if someone cleaned up the office before he came back, the plant would not grow as well as it does now.


    A pot of green plants may not be worth anything before the disaster, but now, such a pot of green plants is rare. In a sense, a pot of green plants is more valuable than Chen Xin''s office.


    Fortunately, there are many green plants in the ecological dome. Compared with the appearance before Chen Xin left, the plants in the ecological dome have become more and more prosperous.


    Some vines in the atrium spread to the ceiling along the supporting columns, gradually winding around the frame at the top of the dome.


    This also makes the whole atrium look full of vitality, at the same time, full of green, quite a wild taste.


    Even before the disaster, such a vibrant indoor courtyard is also a rare sight, not to mention that the external animals and plants have gone through mass extinction, and there is no green in the world, which makes it more difficult to see the scenery in front of us.


    But for Chen Xin, what he wants is not how to enjoy the beautiful scenery, but how to make it more beautiful.


    At present, these plants can grow so exuberantly, which is naturally inseparable from the good environment in the ecological dome. No matter the temperature, light or humidity are regulated, they are kept in the appropriate range to ensure the growth needs of these plants.


    In addition, of course, it is also inseparable from the careful care of these plants every day.


    But the most important thing is the existence of ecological dome, which insulates the cold outside.


    Because the temperature in the ecological dome is kept at an appropriate temperature, the staff here don''t even need to wear protective clothing when they are indoors. They just need to wear ordinary clothes as before the disaster.


    This also makes the life in the ecological dome, to a large extent, has been restored to the level before the disaster.


    Under such circumstances, Chen Xin''s thinking is of course how to promote it, so that more people can enjoy the life before the disaster again.


    It''s just that it''s not an easy thing to do.


    If we just rely on reinforced concrete to build a dome building, so that people can live in it, this is actually very easy to do, and so far, the country is also trying to do such things.


    Before, in the southwest, when the country rebuilt the shelters destroyed by the earthquake, the dome structure was used to build a more livable environment instead of allowing people to live underground for a long time.


    It''s just that there is a big gap between that kind of dome and Chen Xin''s ecological dome.


    You know, Chen Xin''s ecological dome has been upgraded and optimized in many places. Technically, it is too advanced.


    What Chen Xin wanted was not only to build such a small dome, but also to use it as a refuge.


    According to Chen Xin''s idea, what he wants to build is a city that is similar to the kind of city shrouded under the dome in science fiction, relying on the dome to resist external aggression, so that people can live and work in peace and contentment.


    Even if such an exaggerated urban ecological dome can''t be built, a small ecological circle covering an island, such as the one inhabited by pretty boy of Skeleton Island, should be built.


    The city level ecological dome is really too advanced for human science and technology. Even if Chen Xin can get the dome out through system upgrading, it is not very practical and can not be promoted in a sense.


    On the contrary, the kind of small ecosystem with holographic image that pretty boy of skeleton island lived in is very suitable, so we can consider building one.


    In the movie, pretty boy''s small ecosystem is just a small area covering the island. For pretty boy''s large animals, it''s like a stadium in a zoo. Although there is enough activity space, it still looks very small.


    But even so, compared with the figure of a pretty guy, that small area is big enough for humans.


    If Chen Xinzhen can build such an ecological dome, there will be enough space in it to accommodate the next town, or even build a micro city.


    Thinking of this, Chen Xin couldn''t help being moved by his idea.

 Chapter 596

    The idea of Dome City is not new. As early as last century, some architects and science fiction creators have put forward such an idea.


    However, at that time, due to the influence of various factors such as environment and science and technology, although some people tried, they ended up with nothing.


    In these people''s ideas, the dome city should be covered by a huge dome, isolated from the outside rain and snow and other adverse weather effects, at the same time can control and adjust the light, temperature and other factors, to build a perfect living environment.


    There are not many such plans and designs, but because of the huge investment and the strong industrial and technological support, so far, this idea has remained on paper.


    Although there are also some buildings that can be called domes, they do not meet Chen Xin''s requirements.


    The most important point, of course, is that the scale is not large enough.


    At present, most of the domes built by human beings are only individual buildings. No matter how large they are, they are almost the size of a stadium or an airport or a station. Compared with Chen Xin''s expectation of a city scale, they are naturally far behind.


    However, these dome buildings still give Chen Xin a lot of reference.


    In fact, one of the important reasons restricting the emergence of Dome City is that this technology is not very useful under normal circumstances.


    Although it sounds nice to say that a huge dome envelops the city and insulates it from the invasion of rain, snow and other disastrous weather, other effects that follow also need to be considered comprehensively.


    With the constraints of construction cost, construction difficulty itself, and the bigger the city is, the bigger the dome it needs, this kind of thing that looks beautiful and has a bright future will become less practical.


    Another important factor is the dome itself.


    Chen Xin''s Research Center originally used steel structure and glass exterior wall. Although it used new materials, its overall weight is still not light.


    Fortunately, the scientific research center is not too big, and it can be supported by steel structure and glass external wall. In addition, the external wall also has snow removal measures, so there is no risk of bearing too much load and overall collapse.


    But to extend the dome to cover a whole city, the total weight of the steel structure and the glass wall will reach an amazing level.


    So if we want to really build the dome, the materials and structure of the dome itself need to be carefully considered and designed.


    The simpler way is to reduce the height of the dome, widen its arc, and make it into a flat arc similar to the dome of the scientific research center, instead of making a hemispherical cover.


    This can not only save materials, but also reduce the weight of the dome, which can support the dome covering a city in the current situation.


    Arc dome itself can effectively prevent the accumulation of snow, as long as with the appropriate snow removal system, the dome itself is not worried about the possibility of snow fall and collapse.


    Even so, Chen Xin does not intend to continue to use glass curtain wall as the external wall of the dome.


    The first is the weight of the glass itself. In addition, the dome that envelops a city is to be built. Undoubtedly, the consumption of glass is also amazing. He doubts whether there are so many composite glass needed today.


    And using glass dome, construction difficulty and construction period are the problems that need to be faced seriously.


    In contrast, another material is undoubtedly more suitable.


    This material is ETFE membrane, more formally known as ethylene tetrafluoroethylene copolymer membrane.


    Ethylene tetrafluoroethylene copolymer membrane as a crystalline polymer, melting point is 256 ~ 280 ¡æ. It can self extinguish when burning. It has high shear strength and low temperature impact resistance, which is the best among the existing fluoroplastics. It has high impact strength from room temperature to - 80 ¡æ, stable chemical properties, good electrical insulation and radiation resistance.


    It can be said that it is the most ideal material for making dome among all materials at present.


    In the 1990s, this kind of material has been used as covering or film material.


    The water cube, one of the main stadiums of Yanguo 2008 Olympic Games, is also an external wall made of this material.


    If the dome is made of this material, it can achieve the lightest mass with enough strength.


    As for the problem of cold insulation, we only need to cover the outer layer of ETFE membrane with another layer of insulation material to solve this problem.


    With such a large dome that can keep warm and cold, the area covered by the dome can leave the deep underground shelter and resume the life on the ground before the disaster.


    After all, it has been two or three years since the disaster. Although there will still be meteorites falling from the sky, the number has been greatly reduced, and the surface is no longer so dangerous. The safety of the dome city is still enough to guarantee.


    And even if hit, ETFE membrane damage repair, no doubt than the glass curtain wall to the simple, but also more convenient for maintenance and repair.


    After solving the dome problem, the rest of the urban construction problem itself, which does not need to worry, the City builders of Yanguo have enough experience in this area to solve all these problems.


    After such a calculation, Chen Xin found that the conditions for the construction of a dome city are already in place, and there is no technical obstacle to move forward.


    If the dome can be built, with a dome to block the cold outside, even without large heating facilities such as energy tower, the temperature inside the dome will not be too low.


    As long as the internal heat is not lost, the ambient temperature in the dome can be maintained in an acceptable range, so that people who originally need to avoid the cold in the underground shelter can return to the surface life.


    Not to mention, as long as an energy tower is erected in the dome, the temperature in the dome can be the same as that in the scientific research center, so that the four seasons can be like spring, and even support a basic need to restore the ecological environment.


    Thinking of this, Chen Xin has quickly sorted it out according to his own mind, and plans to report it to the state to promote the construction of Dome City.


    However, before reporting, Chen Xin felt that he should first come up with a complete set of design, rather than hand in such a rough plan.


    Although the construction of Dome City is feasible in theory, how much impact such a huge dome will bring, how difficult the construction is, whether it can be successfully completed in today''s environment, if it is to be built, where it is to be built, and how to complete the construction are all things that need to be considered.


    So after Chen Xin hesitated for a while, he decided to improve the whole scheme first, at least after the feasibility study, and then report it.

 Chapter 597

    The idea of building a dome, building a small ecosystem, and then Rebuilding life before the disaster is undoubtedly full of temptation and hope.


    But to achieve all this, it still needs efforts and detailed planning and design.


    Even according to Chen Xin''s idea, the technologies applied in this process are all ready-made technologies or cases, but it still needs a professional design team to plan and design the whole scheme.


    Naturally, this task is not competent by ordinary designers, and even small-scale design institutes are unable to undertake such work.


    Because it''s not just about designing a dome or a small ecosystem, it''s about designing a whole city.


    Even though this city may only be a pocket City, and may not be as big as an urban area or a small town, it is still a super project rarely seen even before the disaster.


    There are few design institutes with engineering design experience of this scale, or even a design institute can not complete.


    If it is before the disaster, it may need several design institutes to work together, one responsible for part, and finally complete the design together.


    Of course, Chen Xin can only report his plan to the state and seek the help of the state, so that the state can assign design institutes and designers with sufficient design ability to complete the work.


    Chen Xin''s plan seems to be much more feasible than the previous mobile base logistics plan. The senior management is naturally very interested in it, and thinks that the difficulty of implementing it is much less than the mobile base logistics plan.


    Therefore, the senior management also strongly supported the plan. They not only gathered experts in relevant fields to demonstrate the feasibility of the whole plan, but also informed all qualified design institutes to come up with relevant design schemes.


    Chen Xinbei is naturally encouraged by the strong support of the state.


    If he can, he doesn''t like living underground. He hopes to live on the ground and enjoy the environment of green water and green mountains.


    After waiting patiently for about half a month, the preliminary design plans from various design institutes gradually gathered here.


    Because the whole plan is put forward by him, he also needs to evaluate these design schemes and select the suitable ones.


    Of course, in just half a month, all the design institutes can come up with is just a simple draft. There is no detailed design. It is only a preliminary planning and the design of the main structure.


    Because the general framework of the Dome City has been finalized, there is no big difference in the layout of the dome itself.


    Some of the designs submitted by various design institutes adopt triangle structure, some adopt hexagon structure, and some adopt irregular design, but generally speaking, most of them are triangle design.


    This kind of design does not have much to spend live, belongs to the very classical reliable design, after all, the triangle is the most stable structure, this is the simplest physics knowledge.


    The structure of the dome needs to support the weight of the whole dome. Naturally, the more stable the better.


    Other structures are not bad, but relatively speaking, Chen Xin prefers classic design.


    After all, this is not a landmark building, nor is it a unique design work that allows designers to display their talents, but a general-purpose building that needs to be promoted on a large scale in the future.


    So the most important thing is to be regular, solid and reliable, practical and durable.


    Therefore, in the dome design, Chen Xin selected the classic design of triangular structure.


    Of course, in addition, he did not exclude some non triangular designs that made him feel bright, and still put them into the range of candidates.


    After all, if there is a better design, he will not reject it.


    In addition to the dome, it''s the part where designers show their skills and talents. It''s also the most important part of the whole design, ground urban planning.


    The space under the dome should be as large as possible, and there should be a certain height, so that there is enough space to accommodate a city.


    For the city under the dome, it is obvious that it can not be like the vast majority of cities, reinforced concrete, high-rise buildings, if so, it does not meet the design requirements.


    At the beginning when the plan passed the high-level review, Chen Xin proposed that the city under the dome must ensure sufficient greening and ecological environment, and at the same time, it should accommodate as many residents as possible.


    This is undoubtedly a difficult requirement, not only to ensure the green and ecological environment, but also to accommodate more people, is undoubtedly a huge challenge for designers.


    It is definitely not feasible to simply reserve the open space for greening, because the total area is limited, and the increase of the green area will undoubtedly reduce the building area, reduce the usable building area, and naturally accommodate less population.


    So how to make a balance between ecology and population has become the top priority.


    Fortunately, those who can receive this task are all excellent national designers, and this little problem can''t defeat them.


    In the first draft that can be put in front of Chen Xin, all the designers are very clever. Some of the excellent designs are even amazing. Only a few of them have no bright spots.


    There is no highlight of the design needless to say, will naturally be eliminated, although there is no highlight and no shortcomings, but with those amazing design, or contrast is too bright and strong.


    Among these wonderful designs, some people combine greening with architecture, which is also in line with the concept of ecological architecture before the disaster. Building indoor ecological garden and hanging garden can expand the building space and area as much as possible to accommodate more people, and ensure the existence of ecological environment as much as possible, so as to make the whole dome city environment more beautiful.


    This kind of design is undoubtedly Chen Xin''s favorite, just like his scientific research center, which has a green environment. Who wants to be full of reinforced concrete?


    So after some screening, Chen Xin quickly picked out his favorite designs.


    In addition, Chen Xin also selected some designs that look not so bright, but also very moderate.


    This is not to make up for the number, but he does not want to influence the final result only by his own personal preferences. After all, these designs are submitted by designers with a high degree of professionalism.


    For the layman like Chen Xin, he didn''t get rid of anything that really made him feel not very good. Instead, he handed over the next screening to the jury specially set up by the state for them to conduct screening from a professional point of view.

 Chapter 598

    In a design institute in a city, everyone is busy with their work in front of the computer.


    This is a very famous and powerful design institute. They have many excellent works and won various awards. They are well-known in the industry.


    However, with the coming of the disaster, the Design Institute, which was originally operated in Shanghai Stock Exchange, had to move to the inland area.


    What''s more, the Design Institute, which was originally a private enterprise, has to be affiliated with a state-owned enterprise design institute and survive on the business allocated by the other party.


    This is also the way for the state to resettle the private enterprises with certain technical strength, such as overall relocation, overall resettlement, retaining the original technical strength, and providing certain business, so that they can continue to survive.


    However, there are not many enterprises that can enjoy this kind of treatment. Only those technology-based enterprises with certain strength and popularity can enjoy this kind of treatment.


    Most of the ordinary enterprises are either closed down, personnel scattered, or swallowed by state-owned enterprises, directly integrated into the body, and few private enterprises can survive.


    Fortunately, the strength of this design institute is still excellent, and the affiliated state-owned enterprise design institute also has a lot of business, so they are barely surviving.


    "Stop your work. I have something to announce." The person in charge of the design institute suddenly came to the office, patted his hands and interrupted everyone''s work, attracting their attention to himself.


    Seeing that everyone looked at themselves, the person in charge continued: "first of all, I''d like to announce a good news. The dome city plan that we assisted the design institute to design has passed the preliminary examination. Just now, the design institute has called to confirm this."


    Hearing the words of the person in charge, everyone cheered. The positive result of his hard work is undoubtedly joyful and worthy of celebration.


    However, the person in charge waved his hand to calm everyone down. Obviously, there is something else to say.


    After everyone calmed down, the person in charge continued: "although we have passed the preliminary examination, it is still uncertain whether we will adopt our scheme, so we can''t relax. Please continue to work hard.


    After that, the design scheme will be jointly designed by us and the design institute. They will be responsible for the design of the dome, heating and other infrastructure parts, and we will be responsible for urban construction and greening. Therefore, the task on hand is still very heavy. "


    After the person in charge said this, everyone in the design institute didn''t have much reaction.


    When they received the design work of the Dome City, they were actually ready for the follow-up work.


    It''s just that I wasn''t sure whether the scheme I designed could pass the preliminary review before, so I didn''t promote it. Now that I''ve confirmed that their scheme has passed the preliminary review, then the follow-up work can be carried out naturally.


    Everyone simply responded to the person in charge and started their own work.


    The follow-up design work of the Dome City has been arranged long before they received this task. Some people have even done part of the work in advance, so there is no need to make more arrangements.


    When the person in charge saw this, he didn''t say anything more. Although in the past, he was bound to boost his morale by means of salary increase and holidays, so as to make everyone''s enthusiasm for work even higher.


    But now in this big environment, there are few things he can do.


    Salary increases and bonus payments are no longer effective. They are more valuable than the money admitted by the state but actually can''t buy things. On the contrary, they are materials and material exchange certificates.


    The material exchange vouchers on the book of Design Institute are all special-purpose, which are used to exchange the materials needed by the operation of Design Institute. General material vouchers are scarce resources, but there are not many on the book of Design Institute. At least we have to wait until this single design task is completed before we can have enough things to issue prizes.


    And tourism, not to mention, this ice and snow, where to travel?


    However, even so, the person in charge said some words of encouragement, let everyone work hard to complete the design task, and strive to win the project.


    Back in his office, the person in charge came up with the previous design plan and planned to see what could be modified.


    Before the establishment of this design institute, he was also a senior designer himself, and he had great talent and talent, otherwise it would be impossible to open such a design institute in a place like Shanghai stock market with his own hard work.


    Only after he became the person in charge, more specific design work was entrusted to his subordinates, and he was more just in charge of the overall situation.


    Because we are cooperating with the Design Institute, the design institute is responsible for the design of the dome and other infrastructure of the dome city. Therefore, this aspect seems to be in line with the rules and has no characteristics.


    But in the layout of the city, the designers of the design institute put forward a bold idea.


    They put the energy tower and geothermal power generation facilities responsible for providing heat and energy for the whole Dome City, as well as the ecological greenhouses for planting crops outside the dome to make more space inside.


    Not only that, they also dug down, expanding the city down, increasing the space in the dome.


    This is indeed a bold and innovative design, and it is precisely because of their difference that Chen Xin chose to let this scheme pass the preliminary examination.


    Compared with the conventional layout of putting the energy tower in the center of the city and building the city around the energy tower, the design of jumping out of the fence is more creative.


    And this is not just a show off. This kind of design really has a very good effect. It not only makes more space available for construction in the dome, but also breaks the restriction of building a city around the energy tower, so that urban planning can have more choices and layout models.


    Because of this, they also removed the ecological greenhouse, another important facility to maintain the operation of the city, from the dome.


    Although the ecological greenhouse is not necessary for every Dome City, the environment in the dome city is much better than the outside world. In this case, it is a good choice to plant vegetables directly in the dome city.


    However, in their plan, although the ecological greenhouse is still connected with the dome, the ecological greenhouse belongs to an area hanging outside the dome, rather than being directly covered by the dome, thus freeing up more space for urban buildings.


    However, even if these two areas are excluded, the dome city is still very small due to the limitation of 5km in diameter. A series of facilities such as administrative area, functional area, residential area and living area need to be arranged in the small space under the dome.


    In order to achieve this, the designers of the design institute almost went bald, but fortunately they finally completed the task.

 Chapter 599

    While the designers are trying to complete the design of the Dome City, Chen Xin is also perfecting a new design.


    It''s just different from the perfect design drawings of designers, Chen Xin is adjusting his design through the nano molecules projected from his wrist watch.


    This is the prototype of the previous mining Titan. Because it can''t be mass produced, it''s only used for design and technical verification. After the mass production of the simplified machine is finalized, this prototype can''t be used and can only be put in the warehouse.


    Chen Xin thinks that this is too wasteful, so he plans to improve it to see if there is any chance to use it again.


    Of course, the answer is yes. Such a Titan can''t be useless. Even if it''s only used as a transport vehicle, it can also be used. It''s just that the input and output are out of proportion.


    Chen Xin, of course, will not do so. What he envisions is to send it to more useful occasions and consider more mass production.


    Although it has been proved that the design of this prototype is not reasonable and it is not suitable for mass production, it is not a problem for Chen Xin.


    The unreasonable design of this prototype is that it is not suitable for working under the mine to a large extent.


    In addition, as a Titan, ordinary workers can''t easily start, and they need special driving training, which undoubtedly increases the difficulty of its promotion.


    If it''s the kind of large mining machinery that can effectively improve mining efficiency, it''s OK. It''s a big deal to train a professional driver.


    Before the disaster, large industrial and mining enterprises will have such specialized operators to operate those professional equipment, which is not a big deal.


    It''s just that the scope of application of the prototype is too narrow now. The professionally trained drivers drive the expensive Titan down to mine. At the same time, the output of mining has not improved a lot, or the input and output are out of proportion.


    Therefore, the key for Chen Xin to improve the prototype is to improve its scope of application and reduce the cost.


    In Chen Xin''s opinion, it is a kind of idea to design prototype machine in the direction of mass production, but its original design idea is not a problem.


    If it''s just for personal use, the exoskeleton is much cheaper than Titan, and it''s easy to operate.


    But if it is used as a mining vehicle, the prototype still has development potential.


    Chen Xin has investigated before. Most of the mines still in operation in China are underground mines. In the past, most of the open-pit mines that were easy to mine were affected by disasters and the snow environment, and production did not resume.


    If the prototype machine can be transformed into one that can carry out large-scale open-pit mining, it will undoubtedly play a great role.


    However, if Titan is to be used in open pit mining, the prototype will undoubtedly be small.


    You know, the open pit is not like the underground mine, where large machinery is usually used to directly dig the whole mountain, break all the rocks and veins together, and then screen out the ore.


    The efficiency of prototype machine is not suitable for mining of this scale.


    Although it can be used more widely on the ground, in this case, the efficiency of the air pick is very low.


    Therefore, we need to redesign the mining tools of the prototype machine, and at the same time, we need to improve its shape, so as to have higher mining efficiency.


    However, while Chen Xin was making such adjustments, he suddenly found that he was not so much improving the prototype as redesigning a machine that could be used for open-pit mining.


    Thinking of this, he simply jumped out of the Titan category and redesigned the large mining machinery directly.


    First of all, the original six legged walking mode can be retained. Although the crawler chassis of normal large construction machinery is also good, in the more complex environment of snow or mine, the walking stability brought by six supporting feet is undoubtedly incomparable to that of wheels and crawlers.


    And the design of the mine cabin can improve the ore-forming bucket. In fact, the closed mine cabin is not very necessary. Whether it is underground or on the ground, it is much simpler to directly open an open mine hopper.


    As for the key to transformation, mining equipment is undoubtedly the top priority.


    The original pneumatic pick is really easy to use on broken rocks, but it is only for people to use, and the production efficiency is not high enough.


    If it is applied to this kind of large mining machinery, it is better to directly replace two hammers, and directly smash them back faster.


    So Chen Xin replaced this redesigned mining machine with two air hammers, which will be used to directly crush large rocks and break rock walls.


    In addition, the original two auxiliary machines, DAAO, will still be used for ore collection.


    But now that the size is enlarged, the mining machine designed by Chen Xinxin doesn''t look like a monster of half human and half spider. On the contrary, it looks more like a giant spider.


    Chen Xin canceled the humanoid design of the upper body, and simply made the large mining machine into a spider shape, which has two huge forearms with air hammers and sharp front ends, which will be used to cut into the rock wall and crush the rock with air hammers.


    The six supporting feet on the side are used to assist walking, and only the two smaller auxiliary big Ao at the front end are used to load ore into the ore hopper.


    The bucket still uses the way of opening at the front end, loading directly from the head to the bucket, instead of having to go around to the back and then throw it in.


    And its size has been enlarged a lot, the whole spider looks like a big truck.


    Its driving system and cockpit are simplified by Chen Xin, and become a similar existence to the truck cockpit. The driver only needs to pull the control lever here to control the machine forward, backward and work.


    Although its driving is still a little complicated, and even inconvenient because of pulling the joystick, it is much easier to train a truck driver than to train a Titan driver.


    Next, we just need to enlarge its engine output to make it have more surging power and stronger output, and then it can become a good mining machine.


    Of course, before that, we should try our best to reduce the cost.


    Chen Xin''s way of reducing costs is more subtle than previous researchers'' way of directly disassembling a Titan into an exoskeleton.


    What''s more, the volume of large machinery itself is placed here, so it is impossible to reduce its manufacturing cost all at once.


    Fortunately, Chen Xin transformed it from Titan into a large-scale machine, many of which can be replaced, thus reducing the cost of the machine. In the end, the cost of the large-scale machine, which is twice the size of the original machine, is much lower than that of the original machine.

 Chapter 600

    "Ah Xin, why do you have such an expression? Is there something wrong with you?" Mo Qingyan noticed a strange expression on Chen Xin''s face and came back from the outside. She couldn''t help asking him a question of concern.


    "Oh, nothing, a little thing." Although Chen Xin said so, the expression on his face didn''t look like nothing.


    On the contrary, he gives people the feeling that he has encountered something embarrassing, like everyone''s black history. He doesn''t want to be known, but he is extremely embarrassed.


    Mo Qingyan probably understood Chen Xin''s expression. Seeing that he said so, she didn''t go on asking.


    On the other hand, Chen Xin''s father noticed that his son''s expression was not normal, and asked with the same concern: "is it a matter of work? What''s wrong with your work? "


    "No, it''s a little thing. I can handle it myself." Chen Xin at this time put on a pair of don''t care, as if it is really just a small matter, not worth mentioning.


    Seeing him like this, the father who knew his temper didn''t say anything more, but told him: "if there is a problem at work, don''t be afraid of trouble, face it positively and deal with it. Since it has happened, we should first find a way to solve it, instead of thinking about how to evade responsibility."


    "I know, Dad." Chen Xin nodded, his face changed, as if he had put down the burden.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    After dinner, he returned to his room. Chen Xin sat at his desk with a bitter smile on his face.


    In fact, Mo Qingyan and her father both guessed what happened to him, but they didn''t go on just to take care of his face.


    But it''s really not serious. It''s just a little accident. It''s like an embarrassing accident. It''s not really a mistake in work.


    In fact, the problem lies in the mining Titan designed by Chen Xin. He just wants to use the existing prototype machine, but ignores the huge difference between open pit and underground mining.


    Underground mining, mainly need to excavate the tunnel, and then break the rock to get ore.


    In this mining process, before the disaster, because of the development of science and technology and the improvement of mechanization, we also began to use a lot of machinery to carry out mining operations.


    In fact, the use of pneumatic pick to break rock by hand was relatively rare before the disaster. Only some relatively small mines chose more primitive mining methods because they could not afford large machinery.


    But after the 21st century, there are fewer and fewer such small mines.


    After the disaster, it is mainly affected by the weather and environment. Many machines can''t work in the low temperature environment of dozens of degrees below zero, because they were not designed to work in this environment at the beginning, so many machines can''t continue to use.


    Coupled with the damage of the national industrial strength, it is impossible to produce large quantities of machinery that can be used in today''s environment in a short time, which leads to many mines still use the more primitive artificial mining method.


    When researchers designed the mining Titan before, it was for this reason that they equipped the Titan with an air pick, and finally simplified the structure into an exoskeleton with an air pick to balance the bucket with supporting feet.


    However, this is not the case with open-pit mines.


    For open-pit mines, they use the method of directly excavating the mountain, and then crushing the excavated ore.


    With the rapid development of science and technology, the blasting in the past has become direct excavation. No matter how hard the rock is, it can''t resist the powerful cutting brought by cemented carbide pick and hydraulic assistance.


    Of course, this is much more practical and efficient than Chen Xin''s air hammer.


    Although it is true that the open pit is unable to operate due to environmental factors, it is not easy to say that the digging head is replaced by an air hammer to smash the ore with brute force.


    After all, the ore really needs to be broken, but it''s not said that it needs to be broken to the extent of crushing.


    This is exactly where Chen Xin was embarrassed. He sent the mining machinery he had designed to the relevant mining department. People probably didn''t know how to respond. In order to avoid hurting his face, he sent him some information about mining machinery for reference.


    As soon as Chen Xin looked at these materials, he immediately understood what was wrong with him. What he did was too taken for granted.


    But fortunately, this is just a design draft, and it''s not really determined to cause such a thing, so it''s nothing more than embarrassment, timely modification and adjustment, and it''s nothing.


    The biggest problem is that Chen Xin made a joke himself. Fortunately, no one will laugh at him for such a thing.


    The mining department is also very interested in his new design, and actively provides information on various mining equipment, so that he can design open-pit mining equipment that can be used.


    After referring to the information sent by the mining department, Chen Xin also has a new idea and plans to overturn the original design and start over.


    The air hammer is replaced by a digging head, and a digging head like a large roller is directly placed in front of the machine body to directly excavate and crush the ore, and then send it to the ore hopper behind the machine body. In this way, the structure can be more simple.


    At least the original mechanical DAAO used to assist in ore collection can be removed. It only needs to design a conveyor belt inside the body to pour the ore excavated by the mining head directly on the conveyor belt, and then the ore can be directly sent to the ore hopper by the conveyor belt.


    In fact, the original mining machinery is such a design, a machine is complex to dig, after the ore is broken, it is directly transported by conveyor belt or large truck, and the efficiency is quite high.


    But the original large-scale mining machinery is really difficult to withstand the current environment, most of them will be frozen and difficult to operate.


    Thinking of this, Chen Xin felt that he might as well transform the original mining machinery directly instead of fighting against the mining Titan here.


    It''s just that there''s no reason to give up halfway since he has done it. He still decides to finish his work.


    Moreover, this design is not completely problematic. As long as the unreasonable parts are corrected, it can still be used.


    Chen Xin thought of this, so he revived his spirit, turned on the computer, called out the data previously sent to him by the mining department, and planned to make a careful study to determine how to modify his design.


    While Chen Xin was working, his door was pushed open, and Qin LAN came in with a snack.


    However, she did not disturb Chen Xin''s work, just put things aside, and then backed out.

 Chapter 601

    While Chen Xin redesigned the mining machinery, the design draft of Dome City, which passed the preliminary examination, has completed the follow-up design and has been submitted by various design institutes.


    Compared with the first draft of conceptual design, the subsequent design drawings are much more detailed, but this is still only a preliminary scheme, mainly to improve the detailed functional area division, various urban design layout and other details that are not included in the first draft.


    As for more detailed design work such as water and electricity pipelines, we will not continue to follow up until we are selected.


    After all, although the designers of various design institutes say that there is no commercial design task now, and they have a lot of leisure work on hand, they are not such a waste of manpower.


    But even so, the number of new design drawings is still amazing.


    In any case, this is to design a whole city, even if it is just a pocket city with a diameter of no more than five kilometers according to the prior requirements, but it still has to have all the functions that a city should have.


    A city should have municipal office buildings, schools, hospitals, commercial streets, residential areas, green belts, parks and so on


    Each functional area needs to be designed separately, and each building needs to have a separate design drawing. Even if it doesn''t need to be designed separately, each building has a detailed internal structure design, but the appearance and size need to be completed in advance.


    Even if this is just a pocket City, in the end, each design is handed in dozens of hundreds of drawings.


    Fortunately, now that the network communication has been restored, and the paper drawings are not easy to transport, the design institutes still submit the electronic drawings.


    This is undoubtedly good news for Chen Xin, which means that he doesn''t need to go through every design one by one.


    Unfortunately, there are more than a dozen designs that have passed the primary election, with tens or hundreds of them each. It takes a long time to quickly turn over all of them, not to mention to carefully look at them in order to review the appropriate scheme.


    Fortunately, the electronic version only needs to transmit these drawings to its own wristwatch, and then it can directly project all the details on the drawings with nano molecules, so as to understand the specific details of the whole design scheme in a more intuitive three-dimensional model way.


    Moreover, for Chen Xin, he can also directly project VR devices with nano molecules, calculate the drawings into three-dimensional images, and experience the feeling of living in the city designed on the drawings.


    Thanks to these two methods, Chen Xin was not slow in reviewing the drawings.


    To pass the preliminary examination, these designs naturally have their own advantages.


    Although the design of this kind of pocket city is estimated to be the first time for various design institutes, it is difficult for them.


    The municipal planning of a city is something that every city will have, and the layout design of this city provides a lot of reference and experience, which makes every design institute perfect in the urban layout planning.


    This is not a boast, because the planning and layout of a city, if viewed from a plane, in the case of limited city size, there is an optimal solution.


    What kind of layout and streets can radiate more areas and make functional buildings play a greater role? In fact, there are standard answers.


    So when the design institutes make their own design perfect, in fact, the planning and layout is a similar result in the end.


    To break the framework of this standard answer, to make innovation, to show different places, is the real design skills of each design institute.


    For example, the design institute cooperating with the design institute put the energy tower and ecological greenhouse outside the dome, which is not uncommon in the designs submitted by various design institutes.


    Most of the designs received by Chen Xin are more or less unique. Only a few of the design drafts have no innovative design or unique place.


    This kind of design draft without these unique designs is obviously not attractive to Chen Xin.


    Of course, he doesn''t want to say that he will just eliminate the design draft without any characteristics. After all, although the standard design has no characteristics, it has one advantage, that is, the standard answer will not have any shortcomings.


    Compared with some special design for innovation, moderate design is more in line with the idea of the mean.


    Unique design sometimes does not necessarily suit everyone, nor does it necessarily meet everyone''s needs and aesthetics, but there will not be such a problem in the standard design.


    Although the standard answer is not amazing, but at least it can be accepted by all, more suitable for a wide range of promotion.


    However, Chen Xin prefers to have some unique designs, or creative schemes.


    Most people can come up with the right answers, but not everyone has the right ideas. It''s more attractive to be able to make their own unique things in addition to the standard answers.


    For example, Chen Xin is now watching this design in VR. The designer creatively adopts the design of ring street, taking three rings of different sizes as the street mode of the whole Dome City, and puts them up in the air, leaving enough green space on the ground. This is a very ingenious design.


    Some of this applies the model of overpass and greening under overpass, but we have to say that this design is very interesting.


    There are three tangent rings. Each ring is closed and unidirectional. The road directions of the three rings are in the same direction. In this way, there will be no traffic jam at the crossroads. It can be said that starting from another way of thinking, the problem of urban traffic congestion has been solved, even the traffic lights are not needed.


    This kind of design is undoubtedly very ingenious and innovative. It breaks the traditional design of straight-line road. Although it seems a little inconvenient at first glance, we can find the convenience of this road when we think about it.


    And the ingenious design like this, in these design schemes Chen Xin got, each one has its own unique place more or less, which makes Chen Xin very surprised.


    It''s just that the design of the dome city will only adopt one scheme in the end. Even if Chen Xin wants to pass more schemes, he will eventually screen out all other schemes and leave only one final scheme.


    If you can, Chen Xin really wants to integrate the advantages of various design schemes, and then concentrate on a set of schemes to gain the advantages of various design schemes and make a design that integrates the advantages of various design schemes.

 Chapter 602

    Having seen all the design schemes, Chen Xin was pleasantly surprised by the excellent designs.


    Each design has its own unique features, among which the highlights can even be overwhelming.


    However, it is precisely because of so many wonderful designs that a brand-new idea was born in Chen Xin''s mind, that is, to blend the amazing designs of various schools together to form a design that is rich in the advantages of many schools.


    For example, the ring road layout is a wonderful design, but only one of the design schemes adopts this design.


    In another design scheme, the green belt and walkway are carried by the building itself to form a design similar to the sky garden, which is also very eye-catching.


    Not to mention Chen Xin''s plan to move the energy tower and ecological greenhouse out of the dome.


    All of these schemes have their own advantages, so why not focus on these rather than choose only one of them and only one advantage among these wonderful designs?


    Chen Xin thinks so and does so.


    He picked out the wonderful parts of each scheme, and then brought these designs together to adjust it into a new scheme.


    In this plan, Chen Xin adopted the design of moving the energy tower and the ecological greenhouse out of the dome, putting them outside the coverage of the dome, and then digging 10 meters under the foundation of the whole Dome City to form a three-layer underground space, expanding the population limit that the city can accommodate.


    This is a design from two different schemes. Chen Xin applied them together, adding more usable space for the dome city.


    The ring road, which has always been his favorite, will not be absent. However, Chen Xin did not directly adopt the design of the ring road. Instead, he turned it into three rings with different heights, only overlapping at the tangent point.


    Among them, the largest outer ring was put on the ground by him, and the foundation fitting the dome became a ring road, which was convenient for the transportation of various materials and the driving of heavy vehicles.


    After being elevated, the middle ring runs through all the functional areas along the circular road, which concentrates the administrative, commercial, educational, medical and other functional areas on this line.


    The inner ring is the residential area of the city, where a large ecological community building from another design is placed.


    This building is also the only one among all the designs received by Chen Xin that takes the whole residential area as a whole building.


    In other design schemes, although there are also schemes that take the whole residential area as a whole, in these schemes, the residential area is still composed of one residential building, not just one building.


    The highlight of this design is not to design the residential area as a residential building in the traditional way, but to design it as a large residential complex.


    Inside the complex, there are various functional service facilities, so that residents can meet their basic living needs without leaving the building.


    And reduce the waste of space between residential buildings and residential buildings, more effective use of space, making the number of people living here greatly increased.


    The combination of sky garden and ecological park ensures enough green area, and does not reduce the green space between residential buildings, which leads to insufficient greening of the whole residential area.


    Combined with the surrounding and connecting of the air corridor, the whole residential area is far more practical than the old residential building design.


    Although the final synthesis of several schemes looks like a research monster, after integrating the advantages of each scheme, the final product is not as bad as expected. On the contrary, it has more advantages than these schemes because it integrates the advantages of each design.


    Looking at the final formed scheme, Chen Xin touched his chin, went into it through VR equipment and experienced it for himself. After finding nothing unreasonable, he decided the scheme.


    Of course, Chen Xin''s so-called decision does not mean that he intends to use the fusion scheme, but that he will transform the fusion scheme into design drawings.


    Chen Xin plans to send this integration of all other designs back to various design institutes, so that they can refer to this integration scheme to modify their original scheme.


    After all, Chen Xin is not a professional designer, and this fusion scheme is just a product of fusion and splicing. It can only be said that as a reference, the real design still needs professional designers.


    However, the purpose of Chen Xin''s doing this is also to hope that the design institutes can combine each other''s advantages with excellent design, gather the advantages of each design institute, and finally design a perfect scheme.


    It''s not because of the screening that some programs with characteristics and highlights will be eliminated, which makes people feel pity.


    And in the final analysis, this design is to design a city. Each design institute can only be responsible for the most distinctive and bright part of its own design, and split the design of a city into several different sub items.


    In fact, there''s no problem. After all, this is the design of a whole city. Even if it''s just a pocket City, the whole design can be divided into several technical packages according to the method of segment bidding, so that each design institute can design the segment that they are good at.


    After making such a decision, Chen Xin contacted the senior management and discussed with them. Chen Xin''s idea was supported by the senior management.


    As a result, the original evaluation scheme was modified, and the integration scheme on Chen Xinji was distributed to various design institutes, so that they could modify it according to the drawing.


    For the design institutes, this is undoubtedly a thing that makes them feel uncomfortable.


    After all, it used to be everyone''s preying on food, and each family relied on their own ability to take the job. Now it turns out that each family relies on their own ability to get only a small piece, which undoubtedly makes everyone very unhappy.


    However, the fusion scheme itself has given them a great deal of shock. After all, they can be valued by Chen Xin and feel that the design with their own characteristics is the essence of each design scheme.


    The scheme that can integrate these essences naturally preserves the advantages of these essence designs.


    Although the shock may not be so strong when gathered together, for these designers who are professional designers themselves, they can feel the design skills and ideas of other people and inspire their own inspiration.


    After many designers see this integration scheme, especially after they find the embodiment of their most proud place in this scheme, they immediately have more updated ideas.


    And these ideas, also let them finally come up with the design become more exciting.

 Chapter 603

    The progress of Dome City is quite smooth. If the dome city can be successfully established, it is undoubtedly an excellent thing for the current Yan state.


    Even in a relatively closed environment, the dome city is more open than the underground refuge.


    If people live underground for a long time, it will cause some problems.


    In fact, in various shelters, managers usually need to face this problem.


    Repressed and closed environment, will undoubtedly increase a person''s psychological pressure, and make it produce a lot of psychological problems.


    Some people may be simply in a bad mood, but some will undoubtedly become depressed or irritable.


    In this eschatological environment, people bear more psychological pressure than before the disaster, and many people''s nerves are always tense.


    Although with the gradual recovery of the country''s situation, living conditions are also slowly improving, but this improvement and change is ultimately limited.


    Life may be just a little more fresh vegetables every day, staple food from old rice to new rice to do emergency food, seemingly insignificant changes in all the signs of life changes.


    But the same changes for ordinary people, it is easy to ignore the past.


    For example, if you only have radish and vegetables every day, and suddenly eat meat one day, and then you can eat it every other day, this is a huge change in your life.


    But if you used to have radish and vegetables every day, but now you just have more lettuce or leeks besides radish and vegetables, you may not feel this change.


    For ordinary people, if they can''t really feel their life is getting better, they can''t reduce their inner pressure. They are always vigilant about their present life, and they are easy to accumulate more inner pressure.


    Under the accumulation of pressure, it is easy to become psychological diseases and various psychological problems.


    Ordinary psychological diseases and psychological problems can be solved by self-regulation and the guidance of psychiatrists, and the country is also aware of this point, and as far as possible for each of the larger shelters are equipped with psychiatrists.


    Even if there is no resident psychiatrist in the small shelters, there will be a medical team equipped with a psychiatrist on a regular basis for inspection, in order to try to ease the psychological problems caused by environmental depression.


    If the plan of Dome City can be carried out smoothly, people will be able to move from the originally depressed underground shelters to live in the ground city, with a good natural environment and relatively more open living space, which can greatly alleviate the psychological pressure caused by environmental repression.


    What''s more, the change of living environment can make people feel the improvement of the quality of life, increase people''s confidence in the country and their expectation of a better future.


    At first glance, the sense of expectation seems to be nothing, but for the people, the simplest life has more hope, and the good days are still in the future.


    This may be difficult for people living in the city before the disaster to feel, because they are under great pressure of life, coupled with the fast pace of life, they can not calm down to experience the changes and beauty of life, and it is more difficult to have a sense of expectation for the future.


    Perhaps there will be a vision at the beginning, but this vision will soon become worthless or forgotten under the pressure of renting, working, overtime and so on.


    But this kind of expectation is an important embodiment of people''s happiness, and creating people''s expectation of future life is also an important means to improve people''s happiness index.


    In today''s environment, to be able to move back from the underground shelter to live on the ground, or to live a life almost the same as that before the disaster in the domed City carefully built by the state, is undoubtedly the dream of many people.


    Although few people will be able to live in the dome city at the beginning, and some people even think that it will give priority to those high-rise and those in power, however, as long as some people can live in the Dome City, and the country continues to build more dome cities, it will undoubtedly make everyone look forward to living in the dome city.


    In this way, even if few people can live in the Dome City, it can greatly stabilize the current social mood and eliminate social hidden dangers.


    The state''s follow-up investment in this area is not just a dome city. In the future, the dome city will gradually replace the existing underground shelters and make living on the ground become the mainstream of human civilization.


    Of course, it also takes time. After all, building a city is not an easy task. Now they haven''t even finalized the drawings.


    However, although the drawings have not yet been finalized, the approximate scale of the Dome City has been determined, and the work of city site selection can be started.


    Although it''s just a pocket City, it''s perfectly possible to rebuild on the basis of the original city in theory, but for the sake of safety, we still need to carefully select the site.


    After all, the geological collapse happened around the city before, which made the people of the city government startled and even alerted the high-level officials to intervene in this matter.


    Because the collapse is not a small area, but a lake in the former urban area. The area of the whole collapse area has reached one third of the urban area before the disaster, and there is a trend that it will spread to the urban area.


    This situation has aroused great attention of the municipal government, specially invited geological experts to conduct a detailed investigation of the collapse area.


    Chen Xin didn''t know the specific investigation results. At that time, he was still in Lucia and didn''t come back. It was only when he chatted with Tang Tang that he learned about it from her.


    It is said that due to the exploitation of underground water in the urban area, coupled with the joint influence of the eruption of DOPA volcano and the southwest earthquake, the geological activity near the urban area has intensified, and the influence of various factors has led to such a result.


    Therefore, if we want to build a domed city in the future, this factor must be taken into account. Otherwise, when the city is repaired, it will encounter geological collapse and the whole city will collapse, which is not a trivial matter.


    In fact, many projects in the country have been affected, especially the reconstruction work in Southwest China.


    The southwest region itself belongs to the area with relatively active geological activities, and the occurrence frequency of geological disasters is also relatively frequent. Affected by this series of events, the production and living activities of the whole southwest region will be continuously affected for a long time in the future.


    Therefore, the country is currently carrying out a large-scale plan to investigate the geological conditions of major cities in the country, in order to have a more comprehensive understanding of the impact of the eruption of DOPA volcano on Yanguo.

 Chapter 604

    Chen Xin is also very concerned about the ongoing national geological survey.


    After all, there is still a way to overcome the cold environment, but if there is something wrong with the earth under your feet, you will really lose your home and shelter.


    So far, however, the results are worrying.


    The impact of the eruption of DOPA volcano is global, and the whole blue star will be affected by it.


    It''s not just that volcanic ash covers the world and earthquakes hit the southwest.


    This is a super volcano, its eruption can even create a species extinction, let the whole blue star into disaster and havoc.


    Although it is not the disaster of mass extinction and global large-scale geological changes as the geological dating, the consequences of super volcano eruption can not be underestimated.


    After all, such a terrible eruption will have a great impact on the plate movement and crustal activity of the whole blue star.


    Especially before that, there were enough meteorites to break through the earth''s crust and fall down. Now is the time to show its impact on blue stars.


    In fact, the national geological survey of major cities in the country also proves this to a great extent.


    Geological activities all over the country tend to become active. Although small-scale earthquakes will not bring any impact, no one can guarantee that with the active geological activities, large-scale earthquakes will not occur.


    Fortunately, at present, the major cities in China are not in the areas with extremely active geology. After all, it is difficult to form big cities in such areas. In ancient times, people would spontaneously avoid such dangerous areas.


    So up to now, the main geological problems found are the subsequent secondary disasters caused by earthquakes, such as cracks, collapses, groundwater level decline and other problems that are not fatal but still troublesome to deal with.


    At present, the geological survey plan is still in progress. According to the national meaning, it means to conduct a survey in the main areas of the country. At present, only the screening of major cities has been completed.


    Although many problems have been found, the good news is that so far, there is no sign of disaster of the same magnitude as the previous earthquake in Southwest China.


    Moreover, due to the influence of environmental factors, some possible geological disasters such as landslides have been eliminated, only avalanches occurred in some areas.


    Although avalanches are also terrible disasters, they are nothing compared with landslides or other geological disasters.


    However, although these geological disasters are not fatal, they also make the current environment worse.


    Apart from other things, because of the earthquake, the groundwater level in many areas has been affected, the water level has dropped, the incoming water has not been available, or the water quality has become turbid due to the earthquake, which will have a great impact on people''s lives.


    Although small-scale earthquakes in some areas will not pose any threat to cities and refuges, mines can not withstand such small earthquakes.


    We should know that the mine itself is destroying the geological structure. Although the development of modern mining technology makes the mine safer, it does not mean that it is really safe.


    Otherwise, before the disaster, there would be no news of mine accidents every year.


    As for the impact of geological disasters on engineering construction, not to mention that, according to the information Chen Yu received, a lot of construction projects were affected by geological disasters, which affected the construction period, and individual projects even had to be relocated.


    On the other hand, because of the large-scale geological collapse and the decline of groundwater level in the urban area, Chen Xin, who originally planned to choose the first dome city here, had to change his mind and consider choosing an area with more stable geological conditions.


    We should know that this area at the junction of Hunan Province and Hubei Province is not only mountainous, but also an area where geological activities were active or the stratum was thin. Otherwise, there would not be so many hot springs underground.


    Now, affected by the previous events, the local geological activities have become active, but it is not conducive to the site selection of the new town.


    In fact, there are many mountains in Hunan Province, but there are not many relatively plain areas. It is not easy to choose a suitable place to build a dome city.


    After all, the diameter of the dome city is only five kilometers, and the whole city is less than a big city. It''s a small city, but it''s also a city, which will accommodate tens of thousands of people.


    In fact, according to the current design, the dome city is expected to accommodate 50000 to 70000 people. If it is crowded, the design will be more compact, and it will not be difficult to accommodate 100000 people.


    With such a large population, the state obviously attaches great importance to site selection. If something goes wrong, no one can shoulder the responsibility.


    So these days, on the one hand, Chen Xin is paying attention to the design drawings, on the other hand, he is also discussing the problem of site selection with geological experts.


    The site selection of this city as a dome city has been abandoned due to geological collapse. After discussing with experts at present, we tend to move the city to the direction of the provincial capital Star City, and build more domes in the future to serve as the new urban area of this city, and simply move this city to its location.


    After all, the city was originally located on the Bank of Dongting Lake, which is a very rich area of groundwater network. In ancient times, it was a part of yunmengze. If the groundwater network system was affected by the earthquake, causing a large range of groundwater level decline and geological collapse, the city would also be threatened.


    It is a very valuable proposal to move the urban area southward to a more stable area and build a new city.


    It''s just that the investment and impact are too great. Even if it''s just building a dome city now, it''s a great project to move a part of the population first, let alone the whole city later.


    For the country, even before the disaster, such a thing is not easy to complete, so this plan is only a proposal at present.


    However, Chen Xin himself is very interested in the idea of connecting multiple dome cities together to form a whole.


    Dome City is only similar to the area of an urban area in the past, even smaller. In this case, a single Dome City obviously can not accommodate the whole population of the next city, even if it is only a small city, and a large number of people have been lost due to the previous disaster.


    So the idea of building new domed cities and connecting them to form a new urban area is very creative.

 Chapter 605

    "I''m out of the door!" In the morning, after breakfast, Cao min finished packing the rest of his emergency food. Then he said hello to his family, carrying his own equipment, ready to go out.


    Before the disaster, Cao min also had a good job and a happy family, but the disaster destroyed his original happy life.


    Today''s Cao min is just an ordinary construction worker. Although it is very different from his previous work, it is not easy to have a stable job in today''s environment.


    Although the state attaches great importance to talents, people with real ability will be recruited by the state to engage in similar jobs as before the disaster, but there are also industry restrictions.


    Talents in technology-based industries such as manufacturing and R & D can naturally find new jobs. However, it is very difficult to find suitable jobs in the tertiary industry such as service and finance.


    In fact, this is also the necessity of the times and the environment. The development of the tertiary industry is based on the overall economic prosperity and development of a country. Because people have money, they want to enjoy more services.


    Poor people can''t even afford to eat, so how can they think of more services?


    That''s why Cao min is just an ordinary construction worker now. In the shelter where he lives, only this job can give him enough income to support his family.


    Because of the post disaster reconstruction, construction workers are in the greatest demand. Although there are better jobs in various shelters, they are not available to ordinary people.


    For ordinary people like Cao Min who have no special skills, the construction workers who simply sell physical strength are the most suitable jobs now.


    Cao min''s work today is not complicated. He just needs to go to the construction site outside the shelter to complete the cleaning of the ruins of the old city and the leveling of the land.


    This is a simple job, only need to have enough physical strength to complete, so there is no difficulty, just a little tired.


    For Cao min, it doesn''t matter if he is tired. Anyway, he is still young. After one day''s work, he goes home to sleep, and the next day he will be full of energy. As long as he has enough income to support his family, it doesn''t matter if he is tired.


    Just as Cao min gathered with his workers on the construction site to start the day''s work, the foreman stopped them.


    "A new project will be launched recently, and some people will be transferred from our side." The foreman gave some unexpected news to the workers, and continued to add: "the good news is that the salary of the transferred workers will be increased by 10%, but the bad news is that the new project is located near the county and far away from the urban area, so all the transferred workers need to live on the construction site before the project is completed.


    Of course, there is still a holiday to come back every week. At present, we sign up on a voluntary basis. Does anyone want to sign up? "


    The foreman''s words made everyone hesitant and excited. It''s no doubt tempting to increase the income by 10% in the current environment. After all, what is sent is not money, but real materials, which can make the family eat and wear warm things.


    But living on the construction site, it can''t help but make everyone feel a little beat.


    Before the disaster, it didn''t matter. It was just poor accommodation and hard work.


    But now this environment, living on the construction site, it''s not only the condition is a little poor, make bad people will freeze to death.


    Of course, the workers also know that since the state has decided to do so, it will not really freeze people to death, and the accommodation conditions should be guaranteed.


    As for living well or not, in today''s world, it''s good to have a place to live. It doesn''t matter at all.


    However, for the vast majority of people, they prefer to live in a safe and familiar environment, rather than take risks in a strange environment.


    However, some people are greedy for more than 10% of their income and raise their hands to show that they are willing to work in new projects.


    Cao min is naturally one of them.


    Although he does not want to leave his wife and family, and he is not greedy for the extra 10% of his income, Cao Min has a reason not to go.


    His wife is pregnant.


    Whether it was before the disaster or in today''s bad environment, it was a happy thing.


    Especially at a time when people''s livelihood is difficult, it''s a happy thing to have more children at home, to have a child between husband and wife, and to be the crystallization of love.


    But it is also a heavy burden.


    Of course, the state has subsidies in this regard. Pregnant women can get half more rations to supplement nutrition, and there are additional subsidies after the birth of the baby.


    This can also be regarded as the state''s encouragement of population fertility in the current environment.


    But even if there are these, in terms of current conditions, it is still difficult to be as good as before the disaster. Apart from other things, the chicken that can be bought casually before the disaster is now what Cao min dare not think about.


    What he can think of and do is just to do more and save more food for his wife and the children to be born, so as not to make the children hungry before they are born.


    In fact, most of the people who volunteer to work on the construction site are like this, either to save more food for their families, or for other reasons. At worst, they are single and want to eat more.


    In short, the foreman soon recruited enough workers and registered them one by one.


    The new project hasn''t started yet. They don''t need to go there so early. Now they just need to confirm the list.


    After watching the foreman register his name, Cao min was relieved. Then he and his workers returned to the construction site and started today''s work.


    Although the country decided to put the newly built Dome City on the other side of the county due to geological disasters, it does not mean that the city side has given up completely.


    Although the area of the collapse is not small, fortunately, it is not an urban area. After some investigation by geological experts, it is determined that the geological structure of the urban area is still stable. Although the groundwater level has dropped, it is not enough to give up the city.


    Therefore, the final plan is to build a new city in the county, but the existing urban area on the urban side will not give up, but will first move a part of the population to the new city, and the urban side will carry out ruins cleaning and land leveling, leaving the possibility of building a dome City in the urban area.

 Chapter 606

    On the construction site of the new city, Chen Xinzheng holds a drawing and discusses the construction with the Engineer in charge of leveling the land.


    "When you level the land, please follow the designated scope. Many places in the new town need to be reserved for planting trees. Don''t directly compact the land. It will be troublesome to plant trees and plants later." Having said the specific questions, Chen Xin half joked and half seriously said a word to the engineer.


    Although this is only a half joke, it is not Chen Xin''s nonsense.


    Although in order to build a new Dome City, the whole land needs to be leveled, and the land needs to be tamped for the construction of new city buildings and dome support, the green area in the new city must be reserved, and even the soil needs to be treated, so as to avoid the impact of subsequent planting.


    In the final analysis, it is also because in the external natural environment, plants are almost extinct. Only a small number of seeds are buried deep in the soil to avoid the previous catastrophe, which is the last kindling left for nature.


    However, it is unknown when the last ignition will be rekindled. After all, in such a cold environment, it is a huge problem for plants to survive, let alone sprout.


    Under such circumstances, it is necessary to pay special attention to the artificial planting of plants for greening. After all, it is not like before the disaster. It is nothing more than a matter of money to plant dead plants or to plant them again.


    Now every plant is extremely precious, and it can only be obtained by artificial greenhouse cultivation. The number is rare, cultivation is not easy, and the loss of any plant is unacceptable.


    The engineer naturally knows this. When he came to understand the key points of construction, someone had solemnly explained it to him.


    So the engineer also nodded his head very seriously and replied to Chen Xin: "academician Chen, don''t worry, we are all professional construction teams, and we have taken over many large projects at home and abroad. We should pay attention to everything! There will be no problem


    When the engineer said this, he looked confident and full of confidence.


    But he didn''t brag about this. Although some of the workers were transferred from other places, they were only grass-roots workers. The construction team brought by the engineers was a very experienced team who had taken over many major projects at home and abroad.


    So he is naturally full of confidence in his speech, and he is also confident to complete the task well.


    Listening to the engineer''s words, Chen Xin naturally felt at ease with him. He didn''t say anything more. He turned around and looked at the construction drawings in his hand again.


    This is the general construction plan of the new city. After several rounds of modification and adjustment, the construction design drawing of the Dome City has finally been determined.


    This set of drawings eventually adopted the design after Chen Xin integrated the schemes of various design institutes. After all, after reading that design drawing, all design institutes affirmed that the design integrating the advantages of various design institutes is indeed better than their individual design.


    As a result, the final design drawings are not contracted to any design institute, but are divided into different design bid sections, which are distributed according to the adopted design parts of each design institute, and different parts are designed respectively.


    In each design institute will be responsible for their own part of the design, this set of design is so out.


    Each design is a different part, in the final integration, there are still some problems, but after coordination, these problems can be solved smoothly, and finally handed over to the construction team.


    Of course, what engineers get now is only the design drawings of some foundation parts, and what Chen novice has is only the general design drawing.


    After all, it''s the design of the whole city, and it''s still a paper version. All the drawings can be filled with a truck.


    Therefore, the drawings can only be the parts that they are responsible for, and only Chen Xin and the superior departments have the general plan.


    Fortunately, this is not a problem. As long as the construction team carries out the construction in strict accordance with the drawings, there will be no problems. Moreover, the design institutes have sent designers to the construction site for this matter, and any problems will be timely adjusted.


    When Chen Xin and others discussed the construction problems, the construction site was also in full swing.


    It used to be an industrial area of the city. Before the disaster, some light industrial factories were mainly set up here. It was also a prosperous industry, which brought good financial revenue to the county.


    However, after the disaster, it was completely abandoned, and the original factory buildings here were basically in ruins after being destroyed by fire, freezing and snow.


    Therefore, it is not difficult for the workers to clean up. Moreover, the original factory building is just a colored tile house with steel beams. After the fire and freezing, there is basically nothing left.


    The only thing that is hard to chew is the cement base on the ground. It is a little troublesome to dismantle these reinforced concrete bases by manpower alone.


    However, this is not as troublesome as the snow clearing on the construction site. In addition, a lot of construction machinery was used in the construction. Generally speaking, it went smoothly.


    In particular, it was originally an industrial zone. There were not many buildings on the land, and the terrain itself was relatively flat. It was an ideal new town construction land.


    Chen Xin watched the workers demolish the original buildings, and the cement and roads on the ground were also shoveled away. He asked the engineers concerned, "do you want to throw away these construction wastes?"


    "No, the removed reinforced concrete will be recycled, the reinforced steel will be used for other purposes, and the construction waste such as cement and bricks will be used for the foundation filling of the new town after being treated." It''s a designer beside Chen Xin who is in charge of the foundation part of his design institute.


    Hearing what he said, Chen Xin became interested and asked him, "do you want to recycle?"


    "Yes, resources are tight now. Although these construction wastes have lost their original functions, bricks and cement blocks are good foundation materials after being crushed again. They also have the function of cold proof and heat insulation. As long as they are laid in the foundation and poured with new reinforced cement, they will be a good construction foundation." The designer seems to be very excited when he talks about this, and he talks endlessly about it to Chen Xin.


    Through the introduction of the designer, Chen Xin can''t help nodding a little.


    It''s true that resources are in short supply now. Resources that can be recycled like this can''t be wasted even if it costs a little.

 Chapter 607

    The construction of the new city began, but Chen Xin did not stay on the construction site this time.


    As far as he is concerned, although the construction of the new city is promoted by him, it does not need him to keep an eye on the construction site.


    After all, his job is to develop new products that can improve the current situation and contribute to national construction, rather than simply focusing on a construction site.


    Although Chen Xin''s main job recently is to design the Dome City, it does not mean that he has no other job.


    The improvement and upgrading of the weather controller has encountered some obstacles. In terms of the science and technology now mastered by the country, it is the limit that the technology can not reach to further improve it.


    Despite the participation of the researchers brought by Chen Xin in Lucia and the deployment of excellent researchers and experts in related fields by the state, the improvements that can be achieved with the existing technology have been completed by these researchers and Chen Xin at the time of Lucia.


    If we want to continue to improve the weather controller, it is only possible for researchers to make new breakthroughs in the field of existing science and technology.


    After all, all the improvements that can be made have been completed. If you want to make new improvements, you can only break the existing conventions and make breakthroughs.


    But it''s not easy to make a breakthrough!


    Reality is not a game. If you click upgrade in the game, it may be finished in an instant. At worst, it''s just a matter of running the progress bar.


    But in reality, if science and technology want to make a breakthrough, it may be more than ten years, or even decades.


    Behind the breakthrough in one field may be the qualitative change brought about by decades of technology accumulation in other related fields.


    Similarly, if a certain research can not make a breakthrough, it may just be that the accumulation of technology in other related fields is not enough.


    This is particularly obvious in the high-tech field. If the accumulation of basic science is not enough, it is difficult to make research achievements and breakthroughs.


    Take the simplest example. For an experiment, the accuracy of the existing experimental equipment can not meet the requirements, which leads to the failure of the experiment. However, another research institution has higher accuracy experimental instruments, and they can succeed in the experiment at one time.


    The difference is only caused by the accuracy of the experimental equipment.


    In fact, this is a very profound lesson and experience for Yan state.


    Now Yanguo''s industrial strength is very strong, and various fields of science and technology have caught up. However, in the 1990s and the early years of the 21st century when Chen Xin was a child, Yanguo did not have such strong industrial strength.


    At that time, Yanguo was already developing a new type of fighter independently, but it was stuck by the aeroengine. Although it is not to say that it could not be built, the things it made were not as good and durable as foreign countries.


    Although there are deep historical reasons for this, China''s technology accumulation in the field of aero-engine at that time was weak, and lack of independent research and development experience.


    But the more essential reason was that the western countries had nearly 100 years of aviation manufacturing and more than 200 years of industrial accumulation at that time, so they were far ahead of us in this respect.


    If we want to catch up with them, we have to go through the technological route and accumulated things that people have spent hundreds of years on in a shorter time.


    Despite the unremitting efforts of the previous generation, we have gradually caught up, but how much effort has been spent and how many researchers have devoted their lives to it is an indescribable number.


    Therefore, to make a breakthrough in the weather controller is not something that can be achieved in a short time.


    This is clear to the researchers who are responsible for the research of weather controllers, and they are ready to fight for a long time.


    After all, there has never been a saying that we are afraid of difficulties because we can''t make breakthroughs in a short period of time. If we just don''t do research because we can''t see hope in a short period of time, then human science and technology can''t make progress today.


    Of course, if there are external forces involved, the breakthrough will be very fast.


    For example, the upgrade system of Chen''s novice can directly break the bottlenecks and barriers and make technology leap forward.


    Of course, Chen Xin also wants to do so. After all, he proposed the plan. He has always been in charge of the project. According to his plan, the weather controller will continue to be upgraded in the future.


    However, for the sake of technology accumulation, the national high level did not let Chen Xin continue to upgrade the weather controller on the mobile base.


    In addition, the country is building another weather controller based on the technical information obtained from the weather controller on the mobile base.


    Chen Xin feels helpless about this, but he doesn''t think it''s wrong.


    In fact, this is the same situation that Yanguo faced at that time in the 1980s and 1990s. It is better to buy foreign technology or engage in technology research and development on its own.


    In this regard, Yanguo has suffered losses more than once. Naturally, it is more reasonable for Yanguo to believe that one step at a time, one step at a time, and he is not willing to upgrade directly. Instead, he hopes that his researchers can make a breakthrough in their research.


    What''s more, when Chen Xin was in Lucia, the researchers have not yet thoroughly analyzed the technical improvement brought about by several upgrades to the weather controller. Now they have smashed new technologies. In a sense, it''s not a good thing.


    Of course, the state has not let Chen Xin, who is obviously open-minded, idle. Recently, his work is not only the design and construction of Dome City, but also many other projects sent by other research institutions that need assistance.


    These projects belong to those that have made breakthroughs in technology and finished products, but still need technical verification and test improvement.


    And it''s much more efficient to send these to Chen Xin, upgrade and improve them, and then go back to reverse analysis, than to spend a lot of time to test and improve them a little bit.


    Originally, this was Chen Xin''s job. However, in consideration of letting Chen Xin create more new things and give full play to his creative ability, the state made some adjustments, so that not so many projects were sent to Chen Xin for upgrading.


    And this has indeed achieved good results, such as Titan and airbags ark, which are very satisfactory to the country.


    Now the state is not asking Chen Xin to completely turn back and upgrade for others. This is mainly because he has spent half a year in Lucia before and accumulated many domestic projects.


    Now that Chen Xin is back, naturally these projects have been sent to his desk and need him to deal with them.


    In fact, after Chen Xin returned to the research center, he spent most of his working time on this, and he squeezed out time to do the dome city design plan.

 Chapter 608

    "What is this?" Chen Xin, holding a list of projects, looks at the latest batch of scientific research project products delivered to the research center, with a strange expression on his face.


    It''s not that he''s dissatisfied with his work, but that the thing in front of him is really weird.


    "Well, this is..." one side of the staff quickly took out another list to check, found the corresponding number, and then quickly said: "this is the latest field survival module developed by the disaster response Institute.


    The purpose of the design is to let the field scientific research and exploration teams carry them, and to set up a shelter that can provide them with certain protection and living space in case of special circumstances. "


    "I can read the instructions." Chen Xin replied to the staff who was not very good. Although he was very grateful for the explanation, he was unable to make complaints about the so-called "field survival capsule" in front of him.


    Because in front of Chen Xin''s eyes, the so-called field survival capsule is like a balloon that has been compressed and vacuumed.


    If you have to find a comparative description, it is about the feeling that the watery white radish is made into preserved vegetables, or that it has been pickled for ten years.


    In particular, the disaster response research institute probably didn''t pay much attention to the modeling and color matching because it was just a laboratory prototype. The dark shell color made it more like an old preserved vegetable.


    No wonder Chen Xinhui make complaints about it. After all, modeling is not like a high-tech product.


    Make complaints about Tucao but Chen Xin will not make complaints about this, or what is the feeling of disapproval.


    He just said to the staff on one side, "send these to my lab. is there a manual for this? If you have, find out. "


    "Yes, academician." The staff quickly nodded, turned around and rummaged through the things sent with the "preserved vegetables", found the supporting instruction manual, and handed it to Chen Xin.


    With the instruction manual, Chen Xin walked to his laboratory while reading it.


    The disaster response research institute is a new research institution established by the state after the disaster. It is a combination of several related institutions before the disaster. It is mainly responsible for the development of various emergency rescue products in the disaster environment.


    After all, the environment is different now, and many emergency supplies need to be redesigned.


    The field survival module they sent is a newly designed emergency rescue supplies, along with some other field survival tools, the whole set of field survival supplies.


    In fact, the state of the old preserved vegetables in the field survival module is not what it is.


    According to the design of the disaster response Research Institute, the field survival cabin is usually folded and vacuumized. When it needs to be used, it only needs to pull the pull ring to inflate in one minute and become a small hard spherical tent that can accommodate two people.


    That''s why Chen Xin saw an old preserved vegetable.


    Limited by the material, not only to be able to vacuum folding compression, but also to have enough strength support after inflation to become a hard sphere, the researchers who designed it can only fill special materials into the outer material.


    This is a newly developed non Newtonian fluid material. Normally, it is a mass of liquid colloid, but it will harden once it is subjected to huge deformation and certain pressure.


    This is also the principle of the new type of liquid protective clothing and body armor. After being impacted, the liquid quickly turns into a solid and has a strong defense ability.


    However, the same thing that comes out of this way... Looks like a lump of preserved vegetables.


    Now Chen Xin''s job is to improve it to make it easier to use and, more importantly, easier to carry.


    After all, it''s an emergency aid, and it can''t be compressed after being inflated. As a disposable, it can''t be too heavy.


    Although the field workers carrying it should be equipped with exoskeletons as auxiliary equipment, and the ability to carry materials is much better than that of ordinary people who only rely on physical strength, the ability to carry more weight is not to say how many can be carried, but also the volume of materials to be carried.


    In fact, the most ideal state should be like the escape ball used in wandering earth, which can be compressed to the limit at ordinary times. It''s just the size of a thermos. When it''s thrown out, it can immediately inflate into a ball that can accommodate two or three people, and it can resist the impact of external forces.


    But it''s a science fiction movie after all. With the existing technology, the material problem can''t be solved.


    Although there are similar inflatable balloons in reality, it is obvious that such things can not be thrown out and inflated by themselves. Moreover, the internal structure is complex and uses a lot of materials, so it can not be compressed to a very small size.


    That''s why Chen Xin is faced with an old preserved vegetable rather than a compressed package.


    Although the field survival cabin can be vacuumized, the non Newtonian liquid material filled in the outer wall can not be impacted by too much pressure, otherwise it will be hard to use, and this also determines that it can not bear too much pressure in the compression state, and it can not be compressed to the limit.


    The researchers of Disaster Response Research Institute have made the best of what they can do, and the design has also met the initial design requirements as far as possible. Although this old preserved vegetable doesn''t look very good, it has actually met the most basic requirements.


    However, it takes a lot of time to improve the volume, weight and convenience of use. Under normal circumstances, it may take two or three years for them to produce more mature products.


    And sent to Chen Xin here, can undoubtedly shorten the improvement process to the extreme.


    After reading the instructions, Chen Xin knew enough about the old preserved vegetable.


    There is nothing wrong with the design of the disaster response research institute. It is also very practical, and the improvement requirements are very clear. For Chen Xin, it is not difficult to deal with.


    At this time, he had the upgrade plan of the wild survival module in his mind.


    It''s obviously not appropriate to change the materials. After taking over this work for so long, Chen Xin also clearly knows that although the upgrade function of the system is good, if his brain is too big, he will directly upgrade the materials into something that modern science and technology can''t make or that is very difficult to make, That will undoubtedly make a product that could have been used unusable.


    After all, whether a product can be applied or not, the most critical issue is whether it can be mass produced.


    So this time, he will try not to move the materials, but adjust the structure to make the field survival module more practical.

 Chapter 609

    The sky is still dark, although there is a trace of white, but it is almost invisible.


    The chilling cold is still there. Although the protective clothing is insulated from the cold, listening to the cold wind blowing outside the helmet and the frost condensation on the mask are enough to make people understand how cold the weather is.


    Stepping on the thick snow, the members of the investigation team are walking hard with deep and shallow feet.


    They are one of the investigation teams of the national geological survey plan. This time, their mission is to carry out geological survey in the mountainous areas around the city.


    As an investigation team sent by the state, the equipment is naturally very perfect. When they set out, they also had specially allocated all terrain vehicles as means of transportation.


    But when they arrived in the mountainous area, because the terrain was rough and the all terrain vehicle couldn''t drive up, they had to leave two team members to guard the vehicle, and the others went into the mountainous area on foot.


    Fortunately, as a geological investigation team, the team members all have rich experience in field scientific research, and in the past, they also walked into the mountains on foot, so they didn''t feel any problem about it.


    It''s just that there is a big gap between the current environment and that before the disaster. If there was such deep snow before the disaster, they would not go into the mountains in any case, because it was too dangerous.


    But now, the whole world has become like this. If you are afraid of danger, don''t do anything. Stay in the shelter and die.


    In addition, they are not blindly adventurous. In addition to the protective clothing that everyone should be equipped with to ensure that they can survive in the wild, they are also equipped with all kinds of other equipment to deal with the danger. In the face of today''s environment, although they still have some danger, they still have the ability to protect themselves.


    "Captain, how long do we have to go?" A member of the team inquired to the team leader through the phone of his protective suit.


    They have been walking for more than half a day, and they have gone deep into the mountains, but the leader of the investigation team didn''t mean to stop, still carrying the team forward.


    According to their original plan, they need to go to a depression in the mountains, set up a camp there, and then investigate, but they are still a long way from the camp.


    So the captain also responded in the phone: "we have to get to the camp to have a rest. At our current speed, we will probably walk another hour. Comrades, hold on a little longer, and we can have a rest when we get to the camp."


    After the captain explained, he didn''t forget to encourage everyone. In fact, he was very tired, but as the captain, he needs to lead his team members, so he can''t complain and be tired at this time.


    After all, if the captain starts to complain and get tired, how can he expect the players to stick to it?


    The captain''s words did encourage the team members more or less. Although they were very tired after a day''s walking, and they knew that they had to build the camp by themselves when they arrived at the camp, they had a little hope in the end and didn''t feel like they were walking blindly.


    Perhaps it was encouraged by the team leader that the front is the camp, and everyone''s pace has accelerated a lot. Although it may be more exhausting, everyone unconsciously wants to arrive at the camp earlier.


    The captain didn''t say much, but he sped up his pace.


    After all, everyone is tied together by a rope, just like a long string. If a person walks fast or slow, it will affect others, so we can only move forward at the same speed.


    This is also a kind of safety guarantee for people to move forward in places like snow mountains, glaciers or swamps. Even if someone falls or falls into a pit or glacier fissure, other people can still hold him, so that he won''t fall to the bottom or be trapped directly.


    In addition to the safety rope, the members of the investigation team also have various field equipment such as locator, signal bomb, ice pick, and some newly produced field emergency supplies to ensure their life safety in the field.


    As the captain moved forward, he pressed a button under his helmet and popped a suction nozzle in his helmet.


    It''s used for eating in the wild. It''s connected with a detachable container, which contains nutrition cream similar to jelly.


    In the wild, if you want to open the mask to eat, you can instantly stick your mouth and food together under the current ambient temperature of dozens of degrees below zero, and the food itself will soon cool down or even freeze.


    So this installation on the protective clothing can rely on the heat preservation effect of the protective clothing itself to maintain the heat, ensure that the food is not cold, at the same time, it can also be very convenient to eat food directly in the process of traveling, and will not delay the time because it is inconvenient to find a place to make a fire and cook in the field.


    It''s easy to say that the food in the container is finished. You can directly replace the container with food. Just remove the empty container and replace it with a new one.


    The nutrition cream contained in such a container is enough to maintain the nutrition needed by a normal adult in a day. It also contains a lot of water. Although it can not provide a sense of satiety, it is practical enough for the investigation team who often do scientific research in the field.


    Moreover, the suction nozzle can be switched to the kettle on the other side to drink warm and palatable hot water, which makes people no longer want more.


    With the help of exoskeleton, they finally arrived at the camp.


    Here is a mountain depression, surrounded by mountain walls, blocking the cold wind around. As long as you set up a tent, it is a perfect camp.


    "It''s a lot better than when we used to build huts with branches!" While commanding the team members to support the tent, the team leader could not help feeling.


    In the past, investigation teams like them came to the mountain for scientific research. After entering the mountain, they basically built a shelter with local materials. It was almost impossible for them to live comfortably.


    Even if the conditions are better and can be equipped with tents, the conditions in the wild are still very difficult.


    But now, they are equipped with all kinds of equipment to ensure that even in the wild, they can still at least have a hot meal and a warm and comfortable quilt to sleep in.


    Just as the people were busy, they gradually put up the tent and were ready to finish the meal, the captain heard some low roars.


    The sound was covered by the strong wind around, mixed in the roaring sound, it seemed that it was hard to hear clearly, but when the captain listened attentively, he suddenly felt the vibration from his feet.


    The snow around seemed to be collapsing, and the roar the captain heard was coming from the mountain wall.


    This made the team leader suddenly surprised and yelled: "avalanche!"


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 610

    "There''s an avalanche!" The captain yelled, and at the same time quickly pulled a striking orange red pull ring on the backpack which had not been unloaded.


    With the captain''s cry, the other team members also noticed the avalanche of snow, quickly found their own backpacks, and did the same action as the captain.


    Huge silver balls spread around them like inflatable balloons. The members of the investigation team quickly got into these balls, sealed the entrance of the ball from inside, and then firmly grasped the handle inside the ball.


    In just a few minutes, everyone has completed the escape action of hiding in the ball, leaving only a ball in place and a camp half built.


    At this time, the team leader hid in the ball and grasped the grip inside the ball. He was very nervous.


    He had encountered an avalanche, but he was very lucky that time. He just watched the avalanche happen far away and didn''t face the threat of the avalanche.


    However, he was deeply impressed by that experience, especially when he saw the avalanche pouring down and completely destroying the mountain forest, which was hard to forget for his whole life.


    So he was very skeptical about the reliability of the so-called emergency survival module.


    However, at this time, they had no better way than to hide in the emergency survival capsule which was only allocated before departure, hoping that the balloon like thing could resist the avalanche.


    The speed of avalanche is very fast. They can''t escape from the avalanche before it comes.


    As the ground shaking became more and more intense, the members of the investigation team were also full of tension and worry. It was just a few minutes, but it was the longest suffering for them.


    Finally, with a growing roar, the avalanche came.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Raise your ears, listen to the outside has gradually quieted down, the captain knows that the avalanche is finally over.


    This made him feel relieved. At the same time, he couldn''t help but secretly congratulated himself that the emergency survival capsule was really effective. Although he was badly hurt in the avalanche just now, he just rolled back and forth in the survival capsule. Besides a little uncomfortable, he didn''t get hurt.


    After the captain lights up the light on his protective clothing and lights up the narrow space in the survival cabin, he checks his health and calls other team members through the phone.


    The space in this emergency survival module is quite small, only one person can curl up in it.


    But it''s also for the sake of safety. In case of danger, if the space is too large and people roll inside, it is easy to cause injury or secondary injury.


    Such a narrow space, let the human body curl up in it, but can play a role in fixing the body.


    Although it''s uncomfortable to roll with the emergency survival module, at least it can ensure that people inside will not break their arms or pin their legs to their heads.


    Through the phone, the team leader confirmed the situation of the team members around him. Generally speaking, it was pretty good. Only two or three people were slightly injured, but they were only minor injuries, not serious, and they could deal with them by themselves.


    It made him feel relieved to wait for the rescue.


    Although it''s a bit frustrating to stay in the emergency survival capsule, it''s much better than climbing out directly.


    Although the emergency survival cabin is inflatable, it is made of very good insulation materials, which can effectively resist the cold outside and maintain the internal temperature.


    So even if the protective clothing doesn''t work, you can stay in the emergency survival cabin for a long time without freezing to death.


    What''s more, they just encountered an avalanche. Even if the weight of the emergency survival module is relatively light, it can expel the rolling snow in the avalanche and float to the upper layer of the avalanche. They may also be buried by the snow at this time.


    At this time, although it is a self-help method to dig out a way to escape while the snow is not frozen, for the sake of safety and insurance, it is better to stay in the emergency survival cabin and wait for rescue.


    After all, before they arrived at the camp, they had walked for a day and consumed a lot of physical strength.


    Originally, they were ready to make a fire to cook and have a good rest, but now they have encountered an avalanche. The team members basically don''t have enough physical strength to dig themselves out of the snow.


    So at this moment, they can only stay in the emergency survival module for a night, waiting for the arrival of rescue.


    Fortunately, the outer layer of the emergency survival module has become hard at this time, which can maintain its own shape and resist the accumulation of snow around, so as to ensure that there will be no danger for these investigators to stay in it.


    Although the team members can''t make a fire to cook and eat steaming food, their protective clothing can still provide them with emergency nutrition cream and drinking water to maintain their survival.


    The only thing you need to pay attention to is not to drink water because you are nervous. After all, you are staying in the emergency survival cabin. It''s a troublesome thing to go to the toilet. No one wants to pee in the small space where you have to stay for a long time. Even if you can''t smell it with a helmet, it will be very uncomfortable.


    The team leader has sent the signal of danger to the two team members guarding the vehicles outside the mountain area through the communication equipment, asking them to ask for help.


    The captain is not worried about whether he will be saved.


    Before the avalanche, they were in a depression, surrounded by mountain walls, so even if they had an avalanche, they were most likely buried in that depression.


    Even if the rescue couldn''t arrive for a while and a half for various reasons, after a night''s rest and recovery, the team members were able to find a way to get out of the snow by relying on their exoskeletons.


    In addition, everyone has a phone and a locator. It has been confirmed just now that everyone is still in touch, and they are also carrying their own backpacks. It is not a problem to hold on for a period of time.


    At this time, the team leader can''t help but be thankful that they encountered an avalanche halfway through the construction of the camp. When they have time to pick up their backpacks and launch the emergency survival module to avoid danger, they can take their own backpacks with them.


    If their camp is built, and they unload their materials and exoskeletons, and are ready to rest before they encounter an avalanche, their situation will be much worse.


    Now they are just a little bit in trouble. As long as they are at ease until tomorrow morning, they can try to save themselves and wait for help.


    Now all they have to do is to fill their stomachs and have a good night''s rest.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 611

    After a night''s rest, the members of the investigation team wake up one after another.


    The internal space of the emergency survival cabin is very narrow. When people stay in it, they can only curl up, and even their legs are difficult to straighten. If they are a little tall, they may have to be squeezed.


    It''s very hard to curl up in such a small space for a night.


    This also leads to the first thing everyone does when they wake up is to knead their bodies, which are extremely uncomfortable because they have been curled up all night.


    But it''s better to stay in the emergency survival cabin for one night than to be exposed to the cold snow outside. So there is no complaint.


    After waking up, the members of the investigation team reported safety to each other on the communication channel and confirmed that no one had any problems or lost contact. After the injured had been bandaged and had a rest all night, they were ready to help themselves.


    Because of the impact of the avalanche, the emergency survival module rolled over for a while, which led to various orientations of the entrance.


    Some are up, some are down, some are behind, some are under the buttocks. Although everyone can understand the reasons for this situation and is lucky to survive, this situation has brought a lot of trouble to the self-help of the team members.


    Fortunately, we all had exoskeletons, and we also had survival tools in our backpacks. After wasting a lot of energy, all the members of the team dug themselves out of the snow.


    Because everyone was together at the beginning. Although they were scattered by the avalanche, no one got lost or separated by the locator and communicator they carried.


    "Captain, I just checked the supplies. The tents and main equipment we carried were washed away by the avalanche. Now there are only backpacks and some supplies we carry with us." One of the team members reported to the team leader with a dejected look that although they were lucky to survive the avalanche, they lost a lot of materials, which undoubtedly means that their investigation mission failed.


    The captain''s face became ugly when he heard this. The loss of tents and materials was a small matter, but the equipment they carried was an important guarantee for them to complete the mission. Now all of them have been lost, which obviously means that they have no way to continue the mission.


    This is the real irreparable loss, especially after the termination of their mission this time, the state has to organize another investigation team to resume their mission. The delay of time and additional resources are very heavy costs.


    And the team leader and other team members who deeply understand this point will not be lucky for the rest of their lives.


    But now that things have happened, the avalanche is an accident that no one wants. We have no way to change the situation. We have to wait for rescue.


    Fortunately, the situation of their distress last night has been reported to the two team members who are responsible for guarding the vehicle. They have also sent a message to the country for help. After learning that the rescue team has completed self rescue and is waiting for rescue, the rescue team soon arrived.


    Because the place where the investigation team was in danger was in the mountainous area, the rescue team came by helicopter.


    Looking at the helicopter with searchlights in the sky and a huge human figure hanging under the belly of the helicopter, the captain couldn''t help looking at the team members and asked him, "isn''t that a Titan? Does rescue need this kind of thing? "


    Nowadays, Titan is becoming more and more familiar. It''s not surprising to see Titan, but it''s a bit surprising to see a Titan hanging from the rescue helicopter.


    The rescue helicopter lowered its altitude and lowered Titan first.


    Watching the huge Titan fall on the snow, splashing a snowflake, the team members do not know what to say.


    Until Titan leveled out a piece of ground for landing, the same huge helicopter landed, the rescue team got off the helicopter, and the leader of the investigation team met up with several members.


    "Thank you for your rescue. Several members of the team were injured. Although they have been bandaged, please take care of them." The captain said this to the rescue team, looking at the giant Titan, and asked, "do we need Titans for rescue?"


    "Considering that you may be trapped in the snow, Titan is necessary." The rescue team explained to the captain, but also quickly let the team members board the plane.


    After they all got on the plane, the plane took off directly, while Titan stayed where he was, as if digging something.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    In the scientific research center, Chen Xin learned from Tang Tang that the investigation team was in danger.


    This is not to say that Chen Xin should be involved in the rescue work, but the rescue team called him shortly after the team was in danger.


    Because the investigation team encountered an avalanche and was in the mountainous area, the rescue team''s own rescue force was not enough to complete the rescue of the whole investigation team, so it was hoped that a large helicopter and a Titan could be borrowed from the scientific research center to carry out rescue in the snow in the mountainous area.


    Tang Tang, as the executive director of the scientific research center, agreed to the loan, but because it was too late, he didn''t tell Chen Xin about it immediately. He didn''t know about it until Chen Xin came to work the next morning.


    "If you can save people, just borrow it. It doesn''t matter." Chen Xin doesn''t care much about it. After all, it''s used to save people. If it''s lent to others, it''s used as long as it''s not the way Liu Bei borrowed from Jingzhou.


    However, it reminded him of another thing, so he asked Tang Tang Tang: "I remember that before the expedition started, it should be equipped with a number of emergency survival cabins, right? They are able to survive the avalanche. Should they use this thing to let Titan recycle the used emergency survival capsule? I need to check the effect when I bring it back. "


    "I''ll call the Titan pilot." Tang Tang nodded and passed on Chen Xin''s explanation to the Titan pilot who went to save people, asking him to bring back the used emergency survival capsule while saving people.


    But Tang Tang and Chen Xin didn''t expect that the effect of the emergency survival module was very good. All the members of the investigation team extricated themselves, and they didn''t use Titan to rescue.


    On the contrary, the emergency survival module buried in the snow was not easy to dig, so Titan dug for a long time and only got a few.


    In addition, after the use of this thing, the surface hardens and the volume expands too much. Even if there is a large helicopter, it can''t bring much. In the end, it only brings a few back.

 Chapter 612

    At the test site of the research center, staff are unloading several silver balls more than one person high from the helicopter cabin.


    "Academician, all the emergency survival pods that can be brought back are here." The crew reported to Chen Xin that these spheres were all the emergency survival cabins they could bring back.


    Looking at the silver ball unloaded from the cabin, Chen Xin nodded and said, "it''s hard. Go and have a good rest. In addition, take these to my laboratory."


    "Yes, academician." One side of the staff agreed, the ball with a small cart after loading, to the side of the elevator transport in the past.


    Although these spheres are actually very light and can roll easily, the staff still did not make the move of rolling these spheres directly to Chen Xin''s laboratory.


    By the time Chen Xin checked the Titan used for mountain rescue and asked the driver about the situation, these silver balls had been sent to the laboratory, and several researchers had begun to check these balls.


    Chen Xin put on his experimental operating suit and put on his protective equipment. Then he went to one of the spheres and asked a researcher who was checking: "what''s the situation of these emergency survival capsules?"


    These emergency survival cabins are the same as the old preserved vegetables that were sent to Chen Xin before. However, after Chen Xin upgraded them, the practicability of these cabins has been changed, so they are equipped to the investigation team as an emergency survival supplies, so that they can be used for practical testing while providing support.


    Although Chen Xin and the disaster response Research Institute did not hope to carry out the actual test in this way, it is obvious that after the avalanche, the investigation team used these emergency survival capsules for escape at the first time.


    So although the first use test is not what Chen Xin expected, now that it has been used, don''t waste this precious opportunity to check the use of these emergency survival capsules.


    These emergency survival cabins are no longer the old preserved vegetables Chen Xin had seen before. All the used survival cabins are silver balls full of air.


    This layer of silver is not a brush paint, but a special layer of heat insulation material. The reason why it is silver is also to isolate heat radiation.


    Chen Xin picked up an art knife and tried to scratch on this layer of material, but there was no trace left.


    Chen Xin was very satisfied with this. Just now, he didn''t just scratch it lightly. Instead, he did it with the force of piercing the outer layer of the emergency survival module. But he didn''t scratch this layer of material, which is enough to show that it is reliable enough.


    In this way, even if you encounter any broken ice or stone tips in the wild, you can at least resist them.


    But even so, Chen Xin used another tool to separate the outer layer of insulation material.


    However, to some surprise, although the outer layer of the emergency survival module was cut, resulting in the internal air leakage, the whole survival module still maintained a spherical shape and did not collapse.


    Chen Xin was not surprised by this, but continued to peel off the outer layer of the whole emergency survival module, revealing a layer of black mesh inside.


    These black meshes are distributed in triangles, and each line is about the thickness of the refill of the ballpoint pen. It looks like a layer of mesh is woven with black threads in the inner layer of the emergency survival capsule, making it the structural support of the emergency survival capsule.


    In fact, it is not wrong to say that the grid formed by these black lines is indeed the structural support of the emergency survival module, but it is not the line used, but the non Newtonian liquid material used by the disaster response research institute before.


    This kind of material will harden rapidly after being impacted. Chen Xin uses this to make a triangular grid like pipe with flexible material in the inner layer of the emergency survival capsule, and then fills these pipes with this kind of non Newtonian liquid material.


    In this way, when not in normal use, flexible materials and liquid non Newtonian liquid materials can be folded up very easily without taking up much space, and can be installed on the backpack to be used as a kind of vehicle airbag.


    However, when it is released and inflated, due to the accumulation of internal gas, the original liquid non Newtonian liquid material will solidify and harden rapidly, becoming the support to support the structural strength of the emergency survival capsule.


    This kind of non Newtonian liquid material has high strength after hardening, even if pressed hard, it is difficult to break or deform it.


    This makes even if the outer layer of the emergency survival module is damaged and the air leaks inside, it can still have a certain outer strength to protect the internal personnel from external impact.


    Of course, it''s weaker in defense than the disaster response Institute''s initial plan to completely fill the outer layer with this material, but considering the cost, this design is more economical.


    Originally, Chen Xin wanted to use memory metal as the structural support of the emergency survival capsule. This material has excellent performance, can quickly restore shape when the temperature changes dramatically, and has the strength and toughness of metal.


    Even if things made of memory metal are crushed or crumpled together, they can automatically recover as long as the temperature changes.


    It was a material that had been around for a long time before the disaster, but it wasn''t used on a large scale because of manufacturing costs.


    Chen Xin is also worried about this point, so he did not use memory metal as raw materials, but used the original non Newtonian liquid materials in a more economical way.


    And from the current use of the situation, this non Newtonian liquid material performance is very good, has perfectly met the design requirements of Chen Xin.


    If we insist on saying what is insufficient, it may be that this kind of material can not be recovered after hardening, which belongs to disposable material, making the whole emergency survival module unable to be recycled.


    Chen Xin didn''t care too much about this. After all, this thing is used to save lives, and it can be used at most once. Who can use this thing every day?


    However, in addition to these problems, Chen Xin is also very concerned about the use of the team members who spent the whole night in the emergency survival module to see if there is anything worth improving in the structure.


    At the beginning, Chen Xin only considered the use of emergency refuge, and did not consider the situation of staying in the emergency survival capsule for a long time in case someone was trapped.


    Now that there is a clear use case, he certainly hopes to be able to understand the situation as much as possible, so as to make improvements later.

 Chapter 613

    Although Chen Xin was studying and improving the emergency survival capsule, when he took apart the emergency survival capsule, he saw the possibility of improving the dome design from the grid structure formed by the hardening of non Newtonian fluid material.


    Although these two things seem to be totally different at first glance, they have something in common.


    The grid structure adopted by the emergency survival module is a complete sphere, and the structural support of the dome is also a sphere. In principle, the two can be regarded as the same structure.


    Therefore, some designs used in the emergency survival module can also be applied to the dome structure.


    However, there is a huge difference between the dome structure and the emergency survival module. If we want to apply the technology used in the emergency survival module to the dome, we need to adjust the technology itself.


    What Chen Xin thought of actually refers to the kind of non Newtonian fluid material that still has a certain degree of elasticity and good supporting performance after it is solidified and hardened by impact. Can we follow the characteristics of this material to enhance the strength of the dome support and reduce the weight of the support structure, so that the dome can be made lighter and larger at the same time.


    In terms of structure, both of them adopt triangular grid support structure, but they are different.


    The triangular support structure is the most stable structure, so it is not unusual to use this structure as the support, and the emergency survival module only adopts a plane structure, while the dome support adopts a more complex three-dimensional structure.


    Although the single-layer plane triangular network structure is also stable, because there is only one layer, and the material itself has a certain deformation, it will have a certain degree of elasticity.


    If it is replaced with a rigid material, it will become extremely hard even if the deformation allowance is eliminated.


    In Chen Xin''s view, this is a place that can be used.


    Although the dome structure needs to be stable, in a sense, it also needs a certain degree of elasticity, that is, shock resistance.


    Because this is a cover covering a city. Although there are few meteorites now, in case of meteorite impact, the dome will bear the brunt and become the first layer of impact.


    It is a feasible way to strengthen the dome material strength as much as possible to resist the impact of meteorite.


    But there is no doubt that the requirements of material processing will become very high, and the requirements of material science itself will also be very high, and a lot of expensive materials will be needed to achieve this.


    This is not unacceptable for Chen Xinhe and the state, but it also lacks cost performance.


    Therefore, if there are cost-effective materials that can be used to strengthen the dome structure, it is naturally the best thing.


    In the current determined urban design drawings of dome, the supporting material of dome structure is high-performance steel, which is constructed into a triangular grid structure in the form of hollow pipe to provide sufficient support and strength.


    The outer layer is made of EFTE material, which is then spliced together to form the outer layer of the dome.


    The reason for this is to resist possible meteorite impact.


    If it''s a large meteorite impact, it doesn''t need to mention anything. Unless Chen Xin builds an energy shield now, otherwise a meteorite will fall down and the whole city will be gone, and there will be no problem of resistance.


    But if it''s a small meteorite, even a little bit of it may fall. The structure of the dome can at least play a buffer role, so that it will not cause great damage to the city under the dome.


    Moreover, even if a part of the single air bag structure is damaged, the damaged part can be replaced, so that the whole dome will not need to be replaced if a hole is damaged.


    Originally, only steel is suitable for this kind of large support structure, and other materials are not suitable in terms of strength or cost.


    But now the appearance of this kind of non Newtonian liquid material gives Chen Xinxin a choice and inspiration.


    The strength of this material after solidification and hardening has been tested. Although it is not particularly outstanding in hardness, its toughness is very good.


    Although the original development idea of this material is to exist as a liquid and harden after being impacted, it can not be used as a kind of material if its characteristics after hardening are used.


    According to Chen Xin''s idea, he wants to use this material to weave a layer of support structure on the surface of the triangular EFTE airbag to enhance the strength of the dome.


    When designing the dome structure, Chen Xin actually discussed this problem with relevant experts, but at that time he proposed to use steel wire as the material, but in this way, the quality was greatly increased, and the steel wire itself was relatively flexible and the support strength was not enough.


    Although we also proposed a series of possible materials such as engineering plastics and carbon fiber, either the cost or the material itself could not meet the requirements, so we had to give up this idea.


    But now the appearance of this kind of non Newtonian liquid material gives Chen Xin a new choice.


    He can use this material to fill the inner layer of the EFTE airbag with the same reinforcement structure as the emergency survival capsule. When the EFTE airbag is impacted by external force, this layer of reinforcement structure can be used as support and buffer to disperse the impact caused by external force and enhance the strength of the EFTE airbag.


    Otherwise, EFTE material itself is also a kind of flexible material, which can''t maintain its own shape after being damaged, which is a certain trouble for the dome.


    For example, although some small meteorites have broken through EFTE airbags, they have only broken through a small hole in the airbags. In this case, if there is no internal support, the airbags will collapse completely.


    Although it is easy to find the damaged area in the subsequent repair, it will also affect the overall performance of the dome.


    But if the airbag itself has a certain strength, even after it is broken down, it can still maintain its own shape, which can maximize the overall shape of the dome without affecting the performance.


    Moreover, even if the meteorite is relatively large and the breakdown area is relatively large, this material can be used as a reinforcement support to maintain the overall shape and structure of EFTE airbag as far as possible, so as not to cause large-area collapse due to the destruction of the lower steel structure support.


    Although Chen Xin''s idea is very good, whether it is practical or not still needs to be tested.


    Now Chen Xin is planning to conduct a simulation test to see if his idea is feasible.

 Chapter 614

    A silver dome stands in the dark. The arc-shaped dome structure gives light from the inside and lights up the whole dome.


    Although the light is not obvious, and the thickness of the dome also restricts the internal light, it still makes the dome like a lighthouse in the dark, which can guide passers-by to return home.


    At this moment, however, a meteor far more dazzling than the dome crossed the sky.


    The friction between the stars and the air ignites the air and burns a bright light, just like a sun rising in the night, illuminating the dark sky.


    Meteor across the sky, falling in the direction of the dome, seems to be deliberately aimed at the dome, want to smash it.


    As the meteor kept falling, it finally hit the dome, broke through the outer insulation material, air bag layer and steel structure support of the dome with irresistible momentum, and fell into the interior of the dome.


    However, when the meteor fell into the dome, everything seemed to be pressed to pause, and all stopped.


    "It seems that after the diameter of the meteorite exceeds one meter, the destructive power will be enough to destroy the dome city." Chen Xin''s figure appeared on the dome where the meteorite broke through. Looking at the place where the meteorite broke through and the flames around the breach, Chen Xin frowned.


    This is the virtual projection he made in the hologram room of the shelter. Through the virtual image, he simulated the possible damage caused by the impact of meteorite on the dome.


    Chen Xin simulated the damage caused by the impact of meteorites of various sizes on the dome. From the smallest one centimeter in diameter to the one meter in diameter, one meteorite after another fell directly on the simulated dome.


    However, through testing, Chen Xin found that in fact, the damage of meteorites to the dome itself is not too great.


    Even when the meteorite with a diameter of one meter hit the dome just now, it did not cause much damage to the dome. It just caused all the EFTE airbags within a radius of 50 meters around the impact point to be jammed, creating a breach with a diameter of about five meters.


    This is not particularly serious damage to the dome itself, which is five kilometers in diameter.


    Although it is necessary to replace all EFTE airbags with a radius of at least 60 meters around the impact point, and replace the steel structure support with a radius of at least 100 meters below, it is still not very serious damage.


    However, for the dome city itself, a meteorite with a diameter of one meter can destroy more than half of the city after impact.


    "So I have no problem with my thinking, but the city itself can''t resist the impact of this series." Chen Xinli explained his ideas and recorded the test results of the last impact in his experimental notebook.


    The main purpose of Chen Xin''s test is to test whether the structural support built inside the EFTE airbag can enhance the defensive performance of the dome.


    After testing, Chen Xin concluded that if the size of the meteorite is small, it will help to maintain the structure of the dome itself and prevent a big hole from being broken by the impact.


    This is mainly because during the impact process, the dome will be impacted and squeezed by the meteorite impact. The closer the EFTE airbag is to the impact point, the easier it is to be squeezed. In this case, if there is a supporting structure inside it, it can undoubtedly maintain the general shape of the airbag, and it will not collapse because of the explosion.


    Of course, there are limits to the supporting structure. With the increase of the meteorite, the scope of compression becomes larger and larger. The closer to the impact point, the more serious the damage of the air bag is. Even the supporting structure itself will be crushed.


    However, the support structure plays a very good role in the airbag which has a certain distance from the impact point. Even if the airbag is jammed, the support structure can still maintain the shape of the airbag without collapse.


    Therefore, this kind of method of erecting support inside EFTE gasbag can really enhance the structural strength of the gasbag itself, but its defense against meteorites has not been greatly improved.


    But it''s normal. After all, it''s a meteorite, not anything else. The force generated by the impact is enough to break through the main armor belt of the battleship. Even if Chen Xin lays a layer of steel plate on the dome, it should be broken down.


    Chen Xin''s original idea is to use the dome as a buffer layer, so that the impact of meteorites on the ground is not so powerful.


    But after testing, he found that it didn''t really work.


    Although the dome does play a certain role in buffering, for meteorite impact, when the meteorite can break through the dome and impact to the ground, the meteorite that can be greatly reduced in impact will not cause too much damage, but the meteorite that can cause large-scale damage can still cause great damage even if its power is reduced.


    What''s more, when the meteorite''s power reaches a certain level, it can directly destroy the whole Dome City, but the dome itself is only hit out of a big hole.


    According to the test, Chen Xin concluded that it is necessary to strengthen the air bag strength, but it is not as reliable as the development of city level shield to rely on it to resist meteorite impact.


    After sorting out his own ideas, Chen Xin turns off the projection of the holographic imaging room and restores it to its original appearance. He is preparing to leave for a rest, but he notices that Qin LAN is standing there at the door.


    "What''s the matter, LAN?" Chen Xin looked at Qin LAN holding her arms at the door and asked her, "what can I do for you?"


    "I can''t find you if I''m ok?" Qin Lanchong Chen Xin replied, walked over to him and asked him, "I see you are doing experiments. Is that the dome city to be built?"


    "Yes, what''s the matter?" Chen Xin wondered why Qin LAN asked this question.


    "When the city is built, can we move in?" Qin LAN looked at Chen Xin expectantly and bit her lip before she continued: "I''m thinking about our future. If we have children, it''s impossible for them to live underground like this, right?"


    "Children?" When Chen Xin heard Qin LAN say that, he couldn''t help thinking.


    It has to be said that Qin LAN raised a very realistic question.


    Although the relationship between Chen Xin, Qin LAN and Mo Qingyan is very delicate, they all want to have children in the future.


    With children, the problem of raising children in the future is a problem that must be considered.


    But for this point, Chen Xin has not carefully considered, he thought about it and said to Qin LAN: "it''s not a big problem to move to the new town. But how do you think about children? "


    "I..." Qin LAN blushes and doesn''t know how to answer, so she simply hugs Chen Xin''s neck and kisses his lips.

 Chapter 615

    Naturally, Chen Xin has thought about children.


    Although many young people of their generation seem to fall into the trend of thinking that they don''t want to get married and have children, it is mainly because they can''t afford to get married and have children.


    However, for Chen Xin, this does not affect him.


    Before the disaster, he was neither unable to get married because he had no money nor the pressure to get married and raise children.


    As a freelancer living in a third tier city, Chen Xin''s contribution income is enough to make him live a comfortable life, no matter whether he is married or raising children.


    As for now, that is not a problem.


    And there is a more critical point, that is, the national policy to encourage fertility.


    Before the disaster, the country has begun to make policy adjustments to encourage fertility, in order to deal with the problem of aging population.


    After the disaster, although the old and frail population was largely eliminated by nature, the reduction of natural environment and living conditions also affected the birth rate and neonatal survival rate.


    After all, in this big environment, adults may not survive, let alone infants.


    Even if the country has provided security as much as possible, and also made policy adjustments, but the overall environment is so, the role of policy adjustments is ultimately limited.


    This is one of the reasons why the dome city plan can be vigorously implemented by the state, because individuals understand the impact of a good living environment on the birth rate and neonatal survival rate.


    And the country is also out of this consideration, so in the future, when choosing the qualification to live in dome new town, it will make a tilt in terms of married couples.


    Of course, for Chen Xin, there is no problem in wanting a new town''s residence qualification.


    Just let him feel headache is how to deal with the relationship between Qin LAN and Mo Qingyan.


    Anyone who marries will be sorry for the other, but it is not in line with the national law to marry both.


    You can''t say that you have two girlfriends with senior leaders. Can the state open a back door for you to marry both?


    Although in terms of the current environmental situation and Chen Xin''s contribution to the country, this kind of thing is most likely recognized by the state with its nose in its hands and will not be taken seriously, it makes Chen Xin feel that it is not very good after all.


    Maybe it''s a little suspected of being cheap and behaving well, but it''s disgusting for people to take the initiative to violate the law when they are taught to abide by the law from childhood to adulthood, and now the state''s violence organs are still in normal operation.


    As for not marrying someone, three people just go on living like this, having children and then being born to support them, which is of course a solution, but it still makes Chen Xin feel sorry for Qin LAN and Mo Qingyan after all, and can''t give them a decent reputation and identity.


    Maybe it''s time to face this problem seriously? Chen Xin felt his conscience and felt that the matter was to be solved. He couldn''t be sorry to Qin LAN and Mo Qingyan.


    They are both good girls. It''s lucky that they are willing to follow them together. They can''t bear any responsibility.


    Seriously thinking about this problem, Chen Xin thinks that he should face it head on.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    On the construction site of dome new town, the land leveling work is being carried out in an orderly way.


    In addition to the workers who are working, there is an engineering Titan specially lent by Chen Xin to the construction team.


    This is a follow-up improvement based on Chen Xin''s original prototype Titan''s practical application experience in rescue and disaster relief in Southwest China. After learning from Chen Xin''s previous experience in designing mining Titan, the latest model of Engineering Titan is redesigned.


    In the process of disaster relief in Southwest China, the role Titan can play is obvious to all, and the country is also very optimistic about this large mechanical vehicle.


    But the cost of Titan is still a little high, and the design of prototype Titan is not prepared for engineering construction, so the design of new model Titan is inevitable.


    Chen Xin spent a lot of time on the design of this type of Titan. He also asked many people for their opinions and corrected some design defects caused by his personal experience.


    Although the final engineering Titan can not be said to have done the best, Chen Xin can at least guarantee that this type of Engineering Titan has at least solved the practical problem.


    The engineering Titan is bigger than the prototype Titan, but this is mainly to increase the strength of the Titan and make it more powerful.


    At the same time, compared with the perfect body defense armor of the prototype Titan, the engineering Titan has been weakened a lot in this aspect.


    The original composite armor equivalent to tank armor has been replaced by pure steel plate. The armor thickness seems to have not changed, but in fact the defense capability has decreased by more than one level.


    Moreover, the cockpit and the Titan''s own joints have also been modified. The joints of the prototype Titan are very flexible, and can make all kinds of movements just like human beings, but this is unnecessary on the engineering Titan.


    Therefore, in addition to some unnecessary joints, Chen xinti not only makes the engineering Titan stupid, but also makes the matching operation much easier.


    It is easy to operate, so the requirements for driving system and hardware are reduced, which makes the cost of Titan project reduced, reaching the national standard.


    On this basis, a number of Engineering titans have been manufactured and applied to the construction of Dome City.


    However, these Titans, like other Titans, belong to scientific research centers, and the nature of working on the construction site is temporarily borrowed.


    After all, engineering Titan is also a Titan. Even if the cost has been reduced a lot, it is still a very expensive construction machinery compared with other Titans.


    In addition, all Titan pilots are trained by the Titan training base of the scientific research center. At present, only the scientific research center has complete Titan maintenance capability, so the state is still letting the scientific research center manage all Titans.


    The military has no objection to this. The general formed a team with Titan and stationed in Titan training base, as if taking it as a base.


    Chen Xin''s visit to the construction site today is largely due to the inspection of Titan''s use at the construction site.


    However, from the current situation, the use of Engineering Titan is quite satisfactory, and the performance in all aspects is also very good. It has played a great role in the construction site and can replace many of the past construction machinery.


    This is naturally a very good signal. After all, most of the construction machinery in the past can not be used in the present environment because of various problems. As a result, most of the engineering construction can only rely on manpower. Now there are new substitutes, which can undoubtedly greatly speed up the progress of engineering construction.

 Chapter 616

    "At present, the land clearing and leveling work has been completed, and we are currently excavating the foundation of the dome and the foundation of the urban architectural planning part." In a meeting room of the construction site, the engineer is introducing the construction progress of the project to Chen Xin.


    The excavation of building foundation is the most important part of the whole construction project. In a sense, it is not too much to regard it as the most important part.


    The foundation of "ten thousand tall buildings rising from flat ground" is the foundation that determines whether the building is firm and durable.


    If the foundation of a building is not well laid, even if the building is built, it is a paper house that can be pushed down.


    For Yanguo, a big country in infrastructure construction, there is no need to emphasize this point. The engineering team of Yanguo can complete the construction according to the requirements of the project without reminding.


    "Well, I''ve seen that just now. It looks like you''ve done a good job." With a smile on his face, Chen Xin seems to be very satisfied with the construction progress of the engineering team.


    When Chen Xin said this, the engineer immediately laughed. Although Chen Xin is not his superior leader, it is obvious that Chen Xin''s recognition is still a happy thing for him.


    However, while praising Chen Xin, he also asked the engineer, "do you excavate the building foundation first, and then construct other supporting facilities?"


    This is what Chen Xingang was curious about when he visited the construction site. The workers are digging the foundation very deep, but they are basically limited to the scope of the buildings planned in the design drawings.


    The rest of the land was only leveled and not excavated.


    However, according to the design drawings, various supporting facilities will also be built on the non building part of the land, so Chen Xin has this question.


    After all, it''s a whole city. It''s impossible to build only houses, and ancillary facilities such as sewers, drainage pipes and heating pipelines will also be laid, not to mention the city level power supply lines and dome lighting system.


    In the future, in this Dome City, lighting is needed to simulate the change of light, so as to artificially create the difference between day and night.


    "Yes, according to the construction plan, the progress of this phase is mainly to excavate the building foundation. As for the supporting facilities, according to the construction plan, the construction will be carried out after the foundation is completed." The engineer explained to Chen Xin that although Chen Xin is not his boss, Chen Xin''s identity is undoubtedly more important than his boss, and the engineer needs to answer any questions he has.


    After listening to the engineer''s explanation, Chen Xin didn''t have any special views or opinions. He didn''t know much about engineering construction, and only asked what he didn''t know.


    However, after the engineer explained, Chen Xin still pretended to be clear and nodded, did not ask anything more.


    However, a designer on one side took the initiative and said to Chen Xin: "this is mainly due to the special situation of the dome city. According to our plan, we will first complete the main construction of the heating tower and the dome, and then raise the temperature under the dome to restore the temperature of the whole construction environment to above zero. In this way, the construction difficulty can be greatly reduced, It can also make the original construction machinery work. "


    Chen Xin can understand this. Most of the original construction machinery used diesel oil. When the diesel oil reaches tens of degrees below zero, even the high-grade diesel oil is easy to condense, which makes the diesel engine unable to start.


    Not to mention that the construction machinery itself is very rough design, and there is no wind and cold proof design for the cab. Even if the driver has protective clothing, the control lever will freeze in this weather.


    However, if the dome insulation can raise the temperature of the construction site under the dome to above zero, these construction machinery which can not be used can be put to great use.


    After all, even with the help of Engineering Titan, excavation in permafrost and ordinary soil are two completely different difficulties.


    Therefore, when formulating the construction scheme, it was proposed that the dome and energy tower should be completed first. In this way, the power can be obtained through the energy tower to ensure the construction power, and the temperature of the whole construction site can be warmed by the dome insulation, so that the frozen soil can melt and the construction difficulty can be reduced.


    "This has been determined before, but I''m not worried about it." Chen Xin nodded and said another thing: "the dome city is an ecological city, and the ecological environment is the most important for the city, so I hope you can also pay attention to this problem in the construction process."


    Since Chen Xin does not emphasize this problem, the dome city emphasizes the important role of ecological reconstruction in its design. Therefore, all parts of the city are built around the core of green ecology.


    Not only is the city full of green plants, including the city''s water cycle, garbage disposal and a series of supporting facilities are designed with the most environmentally friendly design, in order to make the city create the most perfect ecological environment in the future.


    And the construction itself is the most ecological destruction, even in the construction process, no matter how much attention, this will still more or less affect.


    Chen Xin reminded that he also hoped to minimize its impact on the ecology in the construction process.


    Even if there is no ecology on the construction site of the dome city now, after the dome is built, this is the problem that we have to face. If we don''t make preparations now, it will be a big problem in the future.


    For this problem, both engineers and designers have long been in mind. In the previous construction process, they also paid great attention to this point.


    Now Chen Xin mentioned it again. Both of them nodded and said, "please rest assured that we will not be careless about ecological problems."


    While assuring Chen Xin, the engineer also focused on their efforts in the construction process: "we are in strict accordance with the construction requirements in the construction process, and the environmental and ecological protection has been implemented to everyone from the beginning.


    All workers have received relevant education, and relevant responsibilities have been made clear to people. We will make every effort to ensure that the whole construction is safe.


    For the impact on the ecological environment caused by the construction process, the part that can be restored will be restored after the completion of the construction, and the part that cannot be restored will also minimize the damage as far as possible, so as to ensure that the impact on the ecology and environment during the construction process is minimized. "


    "I''m relieved to hear that." Hearing this from the engineer, Chen Xin''s face was even more smiling.


    Now that he has decided to live here, Chen Xin certainly hopes that his new home will have a better environment in the future.

 Chapter 617

    An all terrain vehicle drove out of the gate of the research center and headed for the city.


    Chen Xin in the car today is a rare day off for himself. At the same time, he takes Mo Qingyan and Qin LAN out to relax.


    Although he is the top leader of the Department and giving himself a holiday is a matter of one sentence, Chen Xin is very dedicated and spends most of his time on work.


    Especially during this period of time, he still needs to deal with the backlog of work when he went to Lucia, so Chen Xin doesn''t have much time to take a holiday.


    Fortunately, the backlog is always limited. After spending a lot of time in a hurry, Chen Xin has finished all the backlog and finally has time to take a holiday.


    During the holidays, Chen Xin didn''t want to stay at home all the time, which was a bit boring.


    So he pulls on Qin LAN and Mo Qingyan and plans to go downtown together.


    At this time, Mo Qingyan also suggested that everyone go to her house to dig out her frozen wine.


    After all, it''s her treasure for many years. It''s a pity to be buried under the ice and snow.


    Chen Xin naturally agrees to this matter, and Qin LAN has no objection to it. After all, her training as a Titan pilot is very hard. Since she has time to take a holiday, helping her good friend dig wine is also a soothing thing.


    The goal is decided, and the rest is action.


    Chen Xin asked Tang Tang Tang for a small all terrain vehicle, and prepared the tools for digging, as well as the thermostatic storage box used to preserve Mo Qingyan''s treasures.


    As for his own RV, although it was a better one, Chen Xin didn''t want to drive it because the car body was too big.


    So the three finally drove Chen Xin''s all terrain vehicle from Tangtang and went into the city like this.


    "It seems that the three of us haven''t come out together like this for a long time." In the car, Mo Qingyan looks at Chen Xin who is driving and Qin LAN who is sitting in the co driver''s seat. She can''t help sighing.


    Although she and Qin LAN have already established a relationship with Chen Xin, it is almost impossible to make a date like before the disaster.


    In addition, Chen Xin still has a lot of work to do. They really haven''t been out together for a long time.


    In fact, this is the first time that the three people have come out to play after they have established a relationship, and it''s also the first time after the disaster.


    "After all, there is no place to play in this environment, right? If it wasn''t for protective clothing, the temperature of more than minus 70 degrees outside would frostbite people in an instant. Who would have run out to play with nothing? " After hearing Mo Qingyan''s words, Chen Xin shakes her head slightly and replies.


    For human beings, the low temperature of more than - 70 degrees below zero is very dangerous and fatal. If there is not enough protection, it will be frozen stiff in the real physical sense.


    As for what kind of frozen meat it will be, just think of the frozen meat thrown into the refrigerator. More than - 70 degrees below zero just shortens the freezing process to a very short time.


    In such an environment, there is not enough heat preservation, minutes will be frostbite.


    So naturally, no one will play outside and work outside. There is no way to do that.


    If Chen Xin had not provided the country with protective clothing, which can effectively protect the human body in cold environment, I''m afraid the biggest problem that the country needs to face now is large-scale labor frostbite and complications, right?


    With this idea, Chen Xin has been driving closer to the city.


    The urban area is not what Chen Xin had seen before. After two years of post disaster reconstruction, the urban area is no longer what Chen Xin had seen after the disaster.


    Although there are still a lot of ruins and abandoned buildings, most of the city has obviously been cleaned up, and the main roads seem to be maintained without snow.


    Especially near several shelters, Chen Xin can clearly see that the buildings there are traces of reconstruction and repair, and the lights are back on.


    This is undoubtedly a good phenomenon, because it indicates that the city is constantly recovering, and people are rebuilding their homes bit by bit.


    Although the city may be affected by geological activities, generally speaking, people''s lives are getting better day by day.


    Chen Xin didn''t go deep into the city. He took Qin LAN and Mo Qingyan out, but he came to dig up Mo Qingyan''s frozen treasures. As for the other side of the city, none of them wanted to go.


    So Chen Xin drove directly to the door of Mo Qingyan''s house and then stopped.


    Compared with the last time Chen Xin and Qin LAN came here, the snow is much thicker. Not only the whole yard can''t be seen, but also the buildings beside have been buried.


    If not three people still remember the location, it will take a lot of effort to find it.


    "Hoo hoo, it looks like the snow is deep! If I knew that, I''d let Alain take Titan away. " Chen Xin looked at the snow more than ten meters thick and scratched his head. It''s not easy to dig! Especially the last time he and Qin LAN dug in the channel has been buried in the snow, but it takes a lot of effort to dig in again.


    "Dig slowly. Anyway, it''s OK today. If you drive Titan, what if you dig the house down?" Mo Qingyan doesn''t care about it. Instead, she plays a joke with a smile.


    Hearing what she said, Chen Xin naturally didn''t care. He just shrugged, took out the ready digging tools from the car and handed them to the two women. At the same time, he went to the yard and calculated the location. He planned to dig down the place where he had dug last time to see if he could save some energy.


    Watching Chen Xin start digging snow, Qin LAN and Mo Qingyan naturally come up to help, but they are huddled together with their heads down. Although they say they are also working, they are obviously whispering.


    Chen Xin didn''t care about this. Although he said he could cut into their communication and listen to what they were saying, Chen Xin didn''t eavesdrop on what his two girlfriends were talking about.


    Anyway, I brought them out today to relax. In this case, why not let them do what they want to do?


    As for himself? Digging up the snow early and bringing back Mo Qingyan''s treasures is the main purpose of today''s work.


    You should know that Chen Xin has been thinking about Mo Qingyan''s treasures for a long time, and now she can finally get rid of her dowry. Is it not a waste of opportunities for her to procrastinate?

 Chapter 618

    Because three people were equipped with exoskeletons, even though the tools excavated were simple shovel and hoe, it was easy to dig out the snow.


    The passage that Chen Xin and Qin LAN dug last time was not completely buried. Although the entrance of the passage was sealed by the newly fallen snow, the traces of the passage were still preserved.


    And after Chen Xin, Qin LAN and Mo Qingyan dug up the snow gradually, the last channel was also revealed.


    "It seems that after the last excavation, it was frozen here, so although the back was covered with snow again, the ice wall remained." Chen Xin raised his hand and knocked on the ice wall of the passage, and soon found out why the passage remained.


    Mo Qingyan curiously looks at the passage and asks Qin LAN, "did you dig it when you and a Xin came here last time?"


    "Well, last time we came to check the situation of your house, it turned out that it was completely covered with snow outside. We had to dig a way in." Qin Lan thought of the last time she came with Chen Xin, and the expression on her face became very nostalgic.


    Although it is not a long time ago, but now recall, but still full of memories.


    At that time, her relationship with Chen Xin had just been reconfirmed. Mo Qingyan had not yet expressed her heart to Chen Xin. Even the weather was not as cold as it is now.


    Unlike now, the weather is getting colder and colder, and the relationship between them is totally different.


    Thinking of her first date with Chen Xin here, Qin Lan''s mood has become a little complicated.


    However, since Qin LAN has accepted the three people''s current relationship, she can''t do anything to regret. Moreover, her relationship with Mo Qingyan is actually closer than that with Chen Xin. After all, they know Chen Xin earlier than she does.


    It''s just a pity that two people fall in love with the same person, and they are in the modern world.


    Otherwise, in the ancient environment where three wives and four concubines were allowed by law, this might be the same story as that of e Huang NV Ying?


    Qin Lan''s mind is full of wishful thinking, while Chen Xin takes them down the snow covered stairs carefully.


    The ice here is obviously more serious than when Chen Xin and Qin LAN came last time, and their equipment today is also obviously inferior to the power armor that Chen Xin and Qin LAN wore when they came here.


    But fortunately, exoskeleton is still powerful, plus the shovel in hand, as long as the ice and snow chisel awesome place, it can still be passed.


    It''s just that Chen Xin wants to carve out a place to stay, but the two girls obviously don''t think so. Mo Qingyan directly pulls Qin LAN to the ground, and then slides down the snow covered stairs.


    "Ah Xin, you are too slow!" Mo Qingyan looks back at Chen Xin who is still knocking on the ice and laughs at him.


    Chen Xin felt helpless for a while, but he didn''t say anything. He just said to them, "you two, be careful. Don''t fall."


    "I see, master!" Moqing Yan back to Chen Xin a, this just pull Qin LAN continue to slide down, soon arrived at the bottom of the stairs.


    Chen Xin abandoned some of his kung fu, and after digging out his foothold, he slowly came down.


    It''s not that he has to take the trouble, but later they will dig out Mo Qingyan''s wine from the ice sealed wine cellar and transport it. If there is no suitable foothold, it will be very inconvenient.


    As for the elevator here, when Chen Xin and Qin LAN came together last time, the elevator had already gone on strike. Now he wants to make it work unless Chen Xin is willing to save some peanuts to upgrade it.


    Chen Xindao is not reluctant to give up this survival point, but Mo Qingyan has said before she came that she will not come back to live, and some things naturally do not need to be repaired.


    And even if the elevator is repaired, there is still more than ten meters of snow to dig outside the elevator on the ground. It''s better to take the stairs directly.


    When she comes to the wine cellar, Mo Qingyan looks at the wine cellar which has been frozen tightly. It''s true that Chen Xin and Qin LAN expected that they would cry without tears.


    These wines are treasures she has collected for many years, and some of them can even be called orphans. Now she is really sad to see her precious wine frozen into ice lumps.


    "Don''t worry, there''s still a chance that these wines can be saved. Be careful and take them out first." Chen Xin comforts Mo Qingyan, and then goes into the wine cellar.


    The wine in the cellar is put on the special wine rack, but now it has a thick layer of frost.


    Chen Xin carefully took down a bottle from the wine rack and put it very gently. At such a low temperature, although the glass itself will not become brittle and fragile, there is still a gap between the air pressure inside and outside the glass bottle.


    In addition, the glass bottle itself will freeze together with the wine rack. If Chen Xin is not careful, he will easily break these wine bottles.


    In that case, although Mo Qingyan won''t really kill him, she will be sad for a long time.


    This is the reason why Chen Xin didn''t wear power armor today. After all, if he used power armor, he still didn''t have the easy control power to use directly.


    In fact, in order not to break the wine, he turned off the exoskeletons on his hands and simply took the bottles off the wine rack with his own hands.


    At this time, Qin Lan also found some boxes from the warehouse beside the wine cellar, and put the bottles of Chen Xin''s wine into these boxes one by one.


    When Mo Qingyan saw a box of wine packed, she picked it up and said to them, "I''ll send the wine up."


    "Well, the stairs are slippery. Be careful and step on the place I just dug." Chen Xin exhorts Mo Qingyan, but the action on his hand doesn''t stop.


    There are nearly 500 bottles of good wine in Mo Qingyan''s wine cellar. It''s a big project to take down one bottle and transport it out. It really takes some time.


    In addition to these treasures, Mo Qingyan also had a lot of other ordinary drinks, but today they have moved them.


    However, with the cooperation of the three people, the wine was quickly moved to the all terrain vehicle they came.


    As the wine cellar empties gradually, Mo Qingyan''s mood becomes a little complicated.


    No matter what, it''s her home. Now with the empty of the wine, the connection between myself and here is gradually being untied. Maybe I will never come back here again.


    Thinking of this, Mo Qingyan said to Chen Xin, "ah Xin, I want to get something to commemorate. Would you like to go down with me?"


    At the beginning, Mo Qingyan just went to stay with Chen Xin. There are still a lot of her personal belongings here, but these things are frozen.


    Chen Xin, of course, would not refuse. He nodded and walked downstairs with Mo Qingyan.

 Chapter 619

    After taking some personal belongings of herself and her sister from her old home, which has been completely frozen, and emptying the old wine cellar, Mo Qingyan reluctantly looks at the home she spent a lot of effort to build and leaves with Chen Xin.


    Although not willing to live in her own home, Mo Qingyan knows that she is already very lucky.


    At the beginning of a disaster, you can work with your friends to find a way to deal with the disaster. You can avoid the first wave of disaster in the shelter you build, instead of being displaced like others.


    After the disaster, I can live a stable life with my sister with the help of my reserve materials and friends. I am not in a precarious situation because of the disaster.


    It can be said that the situation of Mo Qingyan and Mo Qingxin is much better than that of most people. Especially when the world is cooling down, they can also live with Chen Xin. They have not been frozen into an ice cellar with this family.


    Although, in a sense, Mo Qingyan may pay more to live in Chen Xin than she and her sister to go to the official refuge, it is already a great happiness for Mo Qingyan to have a safe home and a stable life in this eschatological environment.


    Although life in the country''s official shelters may not be so bad, and now the country''s situation is recovering and getting better day by day, and life is more and more hopeful, Mo Qingyan thinks that if she can have her present life, I''m afraid many people may not mind such things as serving a husband with others.


    It''s just against social morality and national laws.


    However, both Mo Qingyan and Qin LAN really like Chen Xin, and both of them accept each other''s existence and are willing to share with each other.


    This avoids a lot of unnecessary trouble.


    In Mo Qingyan''s opinion, such a relationship is no big deal. As long as the three of them can accept it and do not affect others, it is actually a way to reduce many unnecessary disputes and make the three get along happily.


    Although she didn''t think it was good at first, Mo Qingyan thought it was good after she got along for a long time.


    She doesn''t have to be sad because Chen Xin chooses Qin LAN, and Qin LAN won''t be jealous because she likes Chen Xin, and Chen Xin doesn''t have to be in a dilemma between her and Qin LAN.


    Even before that, she never showed Chen Xin that she liked him.


    But now, she doesn''t need to worry about these problems. She is Chen Xin''s girlfriend now, and she is with him, and has been recognized by his parents. As for the rest, she doesn''t want to think about it.


    To be able to live happily together is what Mo Qingyan wants most now.


    Just before Qin LAN talked to her about another thing, but also let Mo Qingyan some worry.


    That''s about marriage and kids.


    Although she doesn''t mind living with Chen Xin like this, it doesn''t matter if she doesn''t have children even in the name of marriage.


    But Qin LAN seems to value this very much.


    For Mo Qingyan, affected by the unhappiness of her family when she was a child, although she hopes to find a good man, she has a indifferent attitude towards marriage, and even once did not want to get married.


    As for the child, she also has a indifferent attitude. She feels that if she can''t give the child a complete family and care, it''s really unnecessary to give birth to the child and let him bear the pain brought by his parents.


    But in this matter, Qin LAN, who has always been independent and strong, is very traditional.


    She hopes to get married, have children, and teach her husband and children like a traditional woman.


    Of course, it''s not that she wants to be a traditional housewife.


    Qin LAN is a woman with a strong personality, so she is also strong on personal issues. She does not think that women need to abandon their families for their career, nor does she think that it is a weak performance for women to marry.


    On the contrary, she thinks that if she can do the best in her family and career, it is really strong.


    This is one of the reasons why when she was in contact with Chen Xin at the beginning, they broke up because of their different personalities.


    Qin LAN is too strong to give in to Chen Xin.


    However, no matter how strong she was, her self-confidence collapsed after her colleagues died and she lost a hand.


    If it''s just the death of a colleague, it won''t make Qin LAN lose confidence completely.


    It''s a pity that she not only killed her colleagues, but also lost the most important arm for the sniper and the most important support for her self-confidence. This is the most important factor for her to lose self-confidence.


    This is one of the reasons why she wanted to commit suicide at the beginning. Her inner belief has collapsed, and the whole person has lost hope. Giving up life is not an unimaginable thing.


    Although Chen Xin later made a prosthesis for her and cured her, for Qin LAN, it is difficult to establish her collapsed belief.


    Fortunately, Chen Xin has given her new support and renewed her hope for life, which makes Qin LAN get rid of the idea of suicide.


    But this also makes in Qin Lan''s heart, Chen Xin has replaced her original enterprise, has become her new spiritual pillar.


    This also makes Qin Lan''s whole heart flutter on Chen Xin''s body, the whole person''s character has also had some changes.


    As a result, when she finds out that Mo Qingyan also likes Chen Xin, she will want to let Mo Qingyan become Chen Xin''s girlfriend and share a man with her instead of fighting with her for a victory as she used to think.


    Qin LAN didn''t talk about these ideas with others, but Mo Qingyan and Qin LAN knew each other before Chen Xin. In addition, girls often talk about everything, so Mo Qingyan can still detect Qin Lan''s change of mind.


    Especially recently, Qin LAN talked to Mo Qingyan several times about the children''s growth in the future, which makes Mo Qingyan understand Qin Lan''s current state of mind.


    Only for this point, Mo Qingyan is more inclined to go along with fate and does not want to force Chen Xin to make a decision.


    If Chen Xin wants to have children, either she or Qin LAN can have a child and raise it.


    After all, they still have the conditions to raise children. They are not unable to raise a child because of the bad environment.


    As for children''s growth, Mo Qingyan also attaches great importance to it, even more than Qin LAN to some extent, but she doesn''t want to force Chen Xin to make a choice.


    Perhaps it is her childhood experience that makes Mo Qingyan understand that raising a child is a responsibility of both husband and wife. If one of them is forced, the final result will be hard to be happy.

 Chapter 620

    Back at the research center, Chen Xin asks Qin LAN to return the car, while he and Mo Qingyan return the things they brought back to the shelter.


    Because the things brought back are frozen by the low temperature of tens of degrees below zero, suddenly heating up to zero will directly damage these things in the process of thermal expansion and cold contraction, so we must have a gradually warming environment to thaw the things brought back.


    In particular, every bottle of Mo Qingyan''s treasures has become a lone product, and even whether there will be any in the future has become a question. Naturally, we need to cherish them more.


    After all, all the wine producing areas have become extinct. It''s not difficult to make wine again, but it''s extremely difficult to reproduce the unique environment and restore the unique flavor.


    Even Chen Xin dare not say that he can do such a thing.


    This involves not only the temperature and humidity, but also the local natural environment, climate, light, rainfall, and even the soil composition, pH and so on, which will affect the final results.


    Perhaps for ordinary people, it may not make any difference, but for some gourmands, the difference may be as obvious as salty and sweet tofu.


    Therefore, in order to prevent Mo Qingyan''s precious collection from being damaged by thawing too fast, it is necessary to use a very slow speed to thaw these wine bottles that have been frozen into ice lumps.


    You know, for some very old red wine or other liquors, it may be just a shake, or the temperature change brought by palm contact, which may destroy its original delicate flavor. Even if the glass bottle storing liquors can withstand the effect of temperature rise, these liquors may not be able to withstand the same thing.


    This is why a stable and constant temperature environment is needed to store red wine or other liquors, in order to avoid the influence of environmental changes on the flavor of wine.


    Therefore, Chen Xin specially built a new constant temperature wine cellar for Mo Qingyan in the refuge, and this wine cellar had already adjusted the temperature to minus 70 ¡æ before they set out.


    This is naturally Chen Xin''s wine cellar through the system upgrade, so we can achieve such an exaggeration as cold storage.


    After taking all the wine from the incubator and putting it into the wine cellar, Chen Xin and Mo Qingyan were relieved. They closed the door of the wine cellar and switched it to the heating mode. In the next week, the whole wine cellar will slowly heat up at a very slow speed to thaw the wine.


    As for the personal belongings that Mo Qingyan brought back to her and Mo Qingxin, it''s easier to deal with. After all, they are not so delicate and fragile. They just need to control the thawing speed, so that they won''t rise from below to above in a moment, and they will be OK.


    "Don''t worry now? Your babies are going to be fine. " Seeing Mo Qingyan standing at the door of the wine cellar patting her chest with a sigh of relief, Chen Xin couldn''t help laughing at her.


    However, since the two of them knew each other, Mo Qingyan really cherished her wine. Usually, she didn''t let anyone touch her wine. Many times, even if she promised to take a bottle out to share it with everyone, she was very reluctant to give up. At the beginning, those friends often joked about it with her.


    Thinking of this, Chen Xin couldn''t help saying, "when the ice melts, let''s open a bottle to celebrate. Which one do you think is better? The 1982 Chateau voyage? Or that 1956 bottle of concurrent? "


    "No! Neither bottle will do! Let you drink 2009 Chateau Beausejour at most Hearing the two bottles of wine Chen Xin wanted to drink, Mo Qingyan suddenly changed her face and stood in the door of the wine cellar like an old hen protecting her cubs.


    The two bottles of red wine mentioned by Chen Xin are all collected by Mo Qingyan. They are quite rare in these collections. After all, they are all from decades ago, and those that can survive until the disaster are rare. Maybe there are dozens of bottles all over the world, not to mention the fact that even the original place of production has been destroyed.


    It''s probably the last bottle in the world.


    For Mo Qingyan, the wine is her lifeblood. It''s impossible for Chen Xin to drink it.


    Although Chen Xin is the man she loves, she is very persistent in this matter. Her only concession is to take out some second-class treasures that are not so old, hoping to make Chen Xin satisfied.


    It''s just that Chen Xin doesn''t really want to drink these wines. He''s just teasing Mo Qingyan.


    So he didn''t agree. Instead, he put Mo Qingyan on the door of the wine cellar and raised her chin: "if you don''t give me a drink, you''ll have to pay a heavy price!"


    "No! Those two bottles of wine are my most precious treasures. I can discuss the rest. Those two bottles are not allowed! " Although Mo Qingyan feels very shy, she still sticks to it.


    In the face of Mo Qingyan''s coy but persistent appearance, Chen Xin became more and more interested. He deliberately blew air in her ear and said in a very low voice: "but I really want to drink! Do you know how long I''ve been craving it? "


    "Not for long! Those wines have been precipitated for so many years. They should be drunk on a special occasion. How can they be drunk so casually? " Mo Qingyan naturally can feel Chen Xin''s purpose and his body''s reaction to him, but she is not willing to sacrifice her treasure.


    Listening to Mo Qingyan''s words, Chen Xin fondly pinched her chin, pressed her face and asked, "what is a special occasion?"


    "I don''t know!" Mo Qingyan is too shy to see Chen Xin.


    But Chen Xin looks at Mo Qingyan this appearance, on the contrary is more and more exuberant, even starts to attack her, has a kind of irresistible impulse.


    But even so, Mo Qingyan did not let go, just clenched her teeth, silently bear, squeeze out a few words from her teeth: "let you drink something else at most, I really can''t bear those two bottles."


    "What else do you mean?" Chen Xin deliberately misinterprets Mo Qingyan''s words, and has some meaning.


    Of course, Mo Qingyan can understand what Chen Xin is saying, but she is too shy to speak at this time.


    Just when Mo Qingyan is about to collapse in Chen Xinhuai, Qin LAN, who returns from the car, sees the two people who are entangled with each other. She suddenly coughs and asks, "what are you two doing?"

 Chapter 621

    In the end, Chen Xin still didn''t drink the top wines that Mo Qingyan collected.


    It''s not that he has nothing to do with Mo Qingyan. It''s just that, as Mo Qingyan said, these wines are real treasures, and even the orphans in the current environment. It''s too wasteful to drink them casually. It''s more meaningful to wait until a more appropriate time.


    And after all, these drinks are all the private property of Mo Qingyan. Although Chen Xin can bully Mo Qingyan to achieve his goal, everything has a certain degree. It''s not good to make Mo Qingyan angry if he plays too much.


    So Chen Xin finally just let Mo Qingyan take a bottle of wine after all the wine thawed. It''s not so bad, but it''s not so precious. The most important thing is that more than one bottle of wine has opened and everyone drinks it together.


    For Chen Xin, although this is only a small episode, it does make him adjust his state and relax his body and mind through this vacation. The most important thing is to enhance his relationship with Qin LAN and Mo Qingyan.


    Therefore, after the vacation, Chen Xin again devoted himself to the work with a warm attitude.


    However, although Chen Xin devoted himself to his work with enthusiasm, he didn''t have much important things on hand for the time being.


    Other experts sent by the state are already in charge of the weather controller, and limited by the shackles of the development of basic science, it is difficult to make a breakthrough in the short term.


    Although Chen Xin is willing to help, considering the problems of technology development and accumulation, he can only occasionally help upgrade some parts and equipment sent over there, instead of directly upgrading the whole weather controller.


    As for the dome new city, although Chen Xin has to check the construction progress occasionally, the design has been finalized, and he is not responsible for the construction. On the whole, there is nothing wrong with him.


    It''s just to confirm whether the construction progress is in line with the expected construction plan, and check whether there are any mistakes and omissions. Chen Xin doesn''t need to keep an eye on it all the time.


    As a result, Chen Xin seems to have little extra work to do besides his daily work.


    But his daily work doesn''t take up much of his time. After all, the improvement work is backed up by the system upgrade. Basically, it can be completed in a flash every time, and it won''t waste too much time.


    However, Chen Xin''s leisure did not continue. Tang Tang soon found him and put forward a new problem to him.


    "Green plants and animals needed for the construction of Dome City?" After listening to Tang Tang''s question, Chen Xin asked, "why do you come to me for this kind of thing?"


    "Because we are the only research institution that can cultivate individual animals and plants on a large scale in China at present, and our current level of ecosystem research is also the top in China. In addition, you proposed the project of dome new town, so we have to deal with it without bothering two masters." Tang Tang explained to Chen Xin.


    Listening to Tang Tang''s explanation, Chen Xin touched his chin: "shouldn''t you go to see Professor Li? He''s the expert in ecological research. "


    Professor Li is a scientist in charge of ecological agriculture research in the scientific research center. He is also the main leader of the scientific research in the scientific research center. Although he is Chen Xin''s deputy, he is respected by Chen Xin, Tang Tang and others in the scientific research center because of his seniority.


    And Professor Li himself has made great achievements in scientific research. The previous research projects of ecological greenhouse are basically presided over by Professor Li, and many key technological breakthroughs are also the difficulties he personally leads people to overcome, which is a lot of hard work for an old man.


    Moreover, it is precisely because of Professor Li that some researchers who were not convinced of Chen Xin at the beginning of the research center were able to be suppressed and work under Chen''s novice.


    "Professor Li is not very well recently. The old man is old." Tang Tang shook his head and told Chen Xin some bad news.


    Hearing Tang Tang Tang say that Professor Li is not in good health, Chen Xin immediately asked nervously, "is Professor Li OK? What did the doctor say? "


    "It''s not a big problem. The old people may be too tired recently. They may fall down when they are a little old. The doctor says it''s OK, but they should cultivate themselves well." As the administrative director of the scientific research center, Tang Tang naturally wants to have a relationship with Professor Li at the first time.


    Chen Xin was relieved to learn that Professor Li was in good health. At the same time, he understood why Tang Tang Tang found his head.


    "OK, I''ll take care of it, but I can understand why animals are needed in dome new town because it needs green plants." Chen Xin asks Tang Tang Tang suspiciously.


    It is easy to understand the need for green plants. After all, it is to build an ecological city. Green plants are the most important part of the ecological environment, which is not difficult to understand.


    But Chen Xin was confused by the demand for animals. When Professor Li built the ecological greenhouse, he didn''t see the need for animals?


    In particular, the scientific research center itself is an ecological dome environment, where plants grow naturally, forming an ecological cycle, and there is no need for animals to participate in it.


    Tang Tang didn''t explain this to Chen Xin, but just made a helpless expression and said, "it''s hard for me to answer this kind of professional question, but I heard them mention it before. It seems that the scope of the ecological circle that the dome new town needs to build is too large, and animals must participate in it, Otherwise, it is difficult to maintain the operation and self-sustaining of the whole ecosystem. What''s the matter? You can ask the researchers in charge of the project, and they submitted the application. "


    Facing Tang Tang''s attitude, Chen Xin could only nod his head and say, "OK, I know. I''ll go to ask them. However, since they have submitted such an application, there should be a real need. The cultivation of animals and plants will be left to you, Xuejie. "


    "I see. I''ll take care of it." For work, Tang Tang did not show impatience and rebuff. He only complained and joked to Chen Xinban after he agreed to do it. "Speaking of it, I''ve been working here for such a long time. When can I take a vacation for my sister? I haven''t had a holiday in a long time


    "Ah? Xuejie, you are in charge of administration. If you want to take a vacation, don''t you approve it yourself? Do I have to approve it? " Although Chen Xin recognized the meaning of the joke in Tang Tang''s words, he really wondered why Tang Tang didn''t take a vacation.


    Seeing Chen Xin''s response, Tang Tang suddenly said: "you are my immediate superior. How dare I take a vacation without your approval? If you can''t find someone to work with, isn''t it embarrassing to pull me back? "

 Chapter 622

    In the scientific research center, there is a special biological cloning laboratory.


    This is what Chen Xin built when he studied the genetic improvement of wolves, and the biggest achievements here are the big wolf dogs that played an important role in the southwest earthquake.


    They''re all bred here.


    However, after breeding enough populations, these dogs were transferred to other places for breeding and training. The research center is only responsible for the follow-up research, as well as the cultivation and improvement of a small number of individuals.


    So when Chen Xin came to this lab, most of the incubators in the lab were empty, and only a few of them were hatching new embryos.


    "Academician, why are you here?" The researchers who are working see Chen Xin coming and say hello to him.


    Chen Xin nodded his head as a response, and then he said, "dome new town says that building an ecosystem requires animals to join the ecosystem, so we need to cultivate new animals here, so I''ll come and have a look."


    When Chen Xin said this, the researchers nodded: "the city level ecosystem is really inseparable from the participation of animals. When Professor Li studied the eco agricultural system before, he considered that we should cultivate a group of animals to participate in the ecosystem.


    However, the result of the calculation at that time was that the scale of the eco agricultural system was not large enough and the number of animals was too small. It was not only difficult to maintain, but also very troublesome and costly to cultivate animals. Therefore, we chose to maintain the eco agricultural system by means of automatic machinery or manual work.


    Now it is necessary for animals to participate in the construction of city level ecosystem! "


    Hearing what the researchers said, Chen Xin felt his chin and asked him, "I understand the importance of animals in the ecosystem, but it''s not impossible without animals, is it?"


    In Chen Xin''s view, the scale of Dome City is not particularly large. Although it is necessary to build the largest artificial ecosystem in history, with the previous research foundation of ecological agriculture system, it is not impossible to build an ecosystem composed of only plants, and the participation of animals is not particularly necessary.


    "Although it can be done, it would be too expensive to maintain the whole ecosystem." Naturally, researchers have considered similar questions, so they replied to Chen Xin: "not only are plants pollinating, but animals themselves are part of the ecological cycle. Without this part, it is not worth the loss to rely on external forces to maintain the operation.


    Moreover, the addition of animals can also make the whole ecosystem more complete and stable. After all, we are only imitating nature. Only the ecosystem formed by nature itself is the most stable and perfect. "


    Chen Xin can only partially agree with the researchers'' remarks.


    As a part of the ecosystem, animals can make the whole ecosystem more complete, which is certain. It is right that animals can make the whole ecosystem more stable and not easy to collapse, but the ecosystem formed by nature itself is not stable.


    Because with the changes of the natural environment, animals and plants are constantly evolving, and the natural ecosystem itself is not immutable.


    Otherwise, there would not have been so many niche changes in the history of natural evolution, which eliminated the old overlord and brought the new race to the top of the food chain.


    However, Chen Xin would not say this. After all, he just came to confirm the status of the biology laboratory and whether the follow-up animal breeding work can be carried out here. He did not come to discuss the theory of biological evolution with the researchers.


    "How many incubators can we use now?" Chen Xin took a look at the empty incubator around and asked the researchers.


    "There are 120 incubators here, only 20 of which are in use at present, and the rest can be used at any time." Naturally, the researchers are very familiar with the situation here, so the answer is just open mouth.


    Chen Xin nodded with satisfaction and said to the researchers, "in this case, you should be ready to cultivate animals. As for which animals are needed, I will confirm with the project team of dome new town, and then transfer embryos and gene samples from the national seed bank."


    "Good academician, we will be ready." The researcher agreed, and his face was excited. After all, there is nothing to do in the biological laboratory now. It is undoubtedly a happy thing to have a new job.


    And researchers can also hear that this is a big research project. After all, human beings have never tried to build a city level ecosystem before, which is of great significance in studying how human beings live in harmony with the natural environment and building ecological balance.


    Compared with the ecosphere II experiment built by the Federation in those years, it is undoubtedly too large-scale and more meaningful.


    After all, the biosphere experiment No. 2 conducted by the Federation in those years was nothing more than a few scientists and simulated ecological environment. They did not build a complete ecological system, nor did they try to let human beings and ecological environment live together.


    Most importantly, their experiment failed completely for various reasons.


    As a researcher from the field of biology, he is naturally familiar with this period of history. He sincerely hopes that Yanguo can achieve satisfactory success in this aspect, really build an effective and stable urban ecosystem, and realize the harmonious coexistence of human and environment.


    This is an epoch-making research even before the disaster, not to mention that the external ecological environment has been completely extinct and collapsed. Only human beings can reconstruct the ecological system in the greenhouse environment.


    If the harmony between human beings and environment can not be achieved, it means that human beings can not rebuild the ecological environment of blue star, which is a great disaster for human beings.


    Although the blue star itself does not need human beings to rebuild its ecological environment, the mass extinction of species has occurred on this planet more than once, the death of global animals and plants has occurred more than once, and the natural environment will recover itself, it will take at least several decades or even millions of years.


    For the blue star itself, this may be just a flick of a finger, but for human beings, this is a long time scale beyond the whole human development process from the initial evolution to the present civilization.


    Human beings can''t wait that long. Similarly, human beings can''t allow the natural environment to evolve naturally, because no one knows whether human beings can adapt to the natural environment evolved from nature.

 Chapter 623

    Chen Xin can''t help much in ecosystem research. After all, this is not his field.


    However, he is good at biological cultivation.


    After all, Chen Xin personally presided over the whole project when cultivating large cold resistant wolfhounds, and participated in the whole process of cultivation, even including the training and practical use after individual cultivation. Chen Xin participated in it, which can be called rich experience.


    It''s just that the animals needed to build the ecosystem are not large animals, or the demand for large animals is not so great.


    In the natural ecosystem and food chain, large animals usually live at the top of the food chain, which is the last link of the closed loop of the whole ecosystem.


    That is to say, in the cycle that rabbits eat grass, wolves eat rabbits, wolves die in the rotten land, and then grow grass, the niche of wolves.


    This niche is necessary in the natural cycle, because if rabbits have no natural enemies, they will breed unrestricted and eventually break through the limit that the environment can bear, leading to the collapse of the entire ecosystem.


    Kangaroo state has been deeply aware of this, even before the disaster, they are still deeply troubled by it.


    At that time, kangaroo country wantonly slaughtered the top of the local food chain, such as the original kangaroo. As a result, the local rabbits, kangaroos and other creatures lost their natural enemies, and began to breed in large numbers, destroying the grassland, causing a sharp deterioration of the local ecology, a heavy blow to the country''s animal husbandry, and the kangaroos were rampant.


    At that time, kangaroo country also tried to make some efforts, such as banning the hunting of kangaroos, offering rewards to rabbits and kangaroos, but the final effect was very little, and even needed the country to introduce wolves from abroad to curb the breeding of rabbits.


    The reason is that they killed all the organisms at the top of the niche, leading to the loss of balance of the whole biological chain.


    But if you put it in a small ecological environment like a dome City, the existence of this large predator is not necessary.


    It is also easy to understand that such a small ecological environment has limited carrying capacity and can not sustain the survival needs of large predators.


    This is the reason why the old saying says that there are no two tigers in one mountain. Large predators in the wild will have their own territory, and the purpose of expelling other large predators in the territory is to ensure that they can get enough food.


    However, the small ecological environment such as Dome City can carry some herbivorous or omnivorous small animals. Large predators such as wolves and tigers are not necessary, and may threaten the safety of urban residents.


    As for smaller predators such as cats and dogs, they are not suitable for dome cities, but the reason is that they are not suitable for breeding.


    People who have a little knowledge of the ecosystem will know that in the niche, the more organisms at the top of the food chain, the fewer they are and the more difficult it is to reproduce.


    Top predators, such as tigers and lions, can breed three to four cubs at a time, which is a very High-yielding Population. Usually there are only one or two cubs, and they breed once a year, so it is difficult to expand the population.


    As for small and medium-sized predators such as cats and dogs, their relative reproductive capacity is stronger. It''s common to have three or four births.


    If they are smaller animals, they will have more reproduction. Mice, which have more than a dozen babies at a time, are not enough for small creatures.


    The smaller the body size is, the more we can only rely on the number to ensure the continuation of the population.


    This is not the restriction of the world rules in the novel, but the necessity of biological evolution and ecological evolution.


    And the most important thing is that if the dome city wants to maintain the self-sustaining, operation and balance of the ecosystem, it needs more small creatures, such as earthworms, than cats and dogs, which can be regarded as big ones.


    "What if you want to have cats and dogs?" At lunch time, listening to Chen Xin talking about these problems, Mo Qingyan asks Chen Xin with great concern.


    In fact, she has always wanted to have a cat and a cute kitten, which is quite different from Qin LAN, who wants to have a dog and then train to be a police dog.


    "It depends on how you want to keep it. If you just keep it as a pet at home, it''s not a big problem. As long as you ensure that the cats and dogs have enough food, sterilize well, and don''t let the cats and dogs run around, it''s just like keeping pets in the past. It won''t cause too much burden to the ecology." Chen Xin has really considered this issue seriously. As one of the animals most closely related to human beings, cats and dogs must still have many people who want to raise cats and dogs.


    When disaster comes, it is not easy to protect people''s survival. Pets such as cats and dogs are not considered at all. Therefore, in addition to the possibility of keeping some pets or animals in private shelters, no one brings pets into official shelters.


    Now that the situation is getting better and the material supply is guaranteed, there will certainly be people like Mo Qingyan who want to keep pets with her.


    In Chen Xin''s opinion, this is not a big deal. Of course, some people will say that no one has enough to eat and there is nothing to feed their pets. But in Chen Xin''s opinion, as long as people who want to keep pets are willing to pay more labor and the remuneration they get can afford the consumption of keeping a pet, this is not something that can''t be done.


    However, after listening to his reply, Mo Qingyan had some more ideas, so she asked him, "what if the pets run out and become stray cats and dogs?"


    "If that''s the case, we can only hunt and kill." Chen Xin''s words showed a trace of cruelty, but he patiently explained: "stray cats and dogs do serious damage to the ecology. Dogs are a little better, and they don''t have a strong desire to hunt.


    But cats, in their bones, are animals full of hunting impulse. They are also rare animals in the animal kingdom that will hunt for fun. Even if a cat is sterilized and will not reproduce, its existence will pose a great threat to the local ecology.


    So if there are stray animals like cats and dogs in the wild of the Dome City, they can only be killed. After all, the ecology of the dome city is much more fragile than the natural ecology of the original urban environment. Once destroyed, it may bring about the collapse of the entire ecological environment. "


    "Well, I can understand that stray cats and dogs themselves are a very dangerous problem." As for Chen Xin''s attitude on this issue, Mo Qingyan shows an understanding attitude, but her mood is obviously still a little low.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 624

    Of course, Chen Xin sees that Mo Qingyan wants to have a pet. After all, she always wanted to have a cat before the disaster.


    On the one hand, she didn''t have time to raise a cat because she was running a shop. On the other hand, she tried it once. As a result, the kitten she sent died within two months when she met a black heart shop. This left Mo Qingyan a big psychological shadow.


    This also caused Mo Qingyan on the one hand wanted to raise a cat, but on the other hand, she did not dare to raise a cat easily, for fear of meeting the same situation at the beginning.


    After the disaster, it''s even more impossible to keep pets. People don''t have enough to eat. How can they have extra food to keep cats?


    However, for Chen Xin now, he feels that he can satisfy Mo Qingyan''s wish.


    It''s not a lot of effort to cultivate a cat and give it to her as a pet by means of laboratory.


    And Chen Xin is seriously considering whether to open pet raising in Dome City.


    It''s just that Chen Xin doesn''t know much about this. He decides to consult some experts who are more knowledgeable.


    "Professor Li, how are you? Is it better? Take good care of yourself Chen Xin came to the sanatorium of the scientific research center and visited Professor Li, who was undergoing treatment.


    In fact, Professor Li''s condition is not serious. It''s just that when people get old, they really lack energy. In addition, their health is getting worse and aging. A little illness may develop into a big problem.


    So even if Professor Li himself said that he didn''t need to stir up the public with a little trouble, Tang Tang still didn''t dare to neglect the arrangement of the doctor and the best convalescent ward, so that Professor Li could cultivate himself well.


    Professor Li was also very happy to see Chen Xin. After a few simple greetings, he asked about his work.


    "You don''t have to worry about work. Director Tang will take care of it, and your students are all trained by you? You can''t trust them? " Chen Xin explained to Professor Li the recent work of the scientific research center and relieved the old professor.


    In the face of Chen Xin''s consolation, Professor Li said with a smile: "I understand that although all my students are good, they are still inexperienced. I need an old man to guard them. This can be regarded as an old man''s stubbornness. I''m always worried about these young people. It''s also the old man''s old fault. I''m always idle and I love to worry about this and that. "


    Although the young people in Professor Li''s mouth are actually middle-aged people in their 40s and 50s, in Professor Li''s eyes, they are still the students who listened to his lectures.


    Chen Xin didn''t say much about Professor Li''s attitude. He could only continue to comfort Professor Li for a few words before he talked about his main purpose.


    "Professor, our country is preparing to build a dome city. We need to build an ecological system in the city. At present, the scientific research center is organizing the cultivation of animals and plants. What animals do you think are needed in this aspect?" Chen Xin asked Professor Li for advice.


    When he heard Chen Xin''s question, Professor Li''s happy expression suddenly became serious. After thinking about it carefully, he replied: "this question is not easy to answer! Before the disaster, the animals in the urban environment were mainly the wild animals left in the process of urban development, mainly mice and other small animals, insects and birds. Large wild animals were extinct in the city.


    In addition, there are domesticated and imported animals, which together form the wild animal population in the urban environment, but they are only a part of the whole ecosystem.


    For example, fish and shrimp, frogs, plankton, microorganisms in rivers, and even human beings living in cities can be included in the animal groups of the whole ecosystem. "


    Professor Li''s words made Chen Xin raise his eyebrows. At the same time, he quickly took out a book and recorded what Professor Li said.


    Seeing that Chen Xin took out the book records, Professor Li adjusted his thinking and said more seriously: "from the perspective of a city, the two groups of animals and plants in the urban ecosystem should be linked. For example, if you are greening in the urban area, you should consider whether there is a relationship between the animals you put in and the greening plants you use.


    If the animal you put in can''t eat this plant, or there will be toxic reaction after eating, etc., these are the problems that need to be considered.


    Therefore, we need to integrate them to build a stable food chain and supply-demand relationship, so that every animal and plant in this ecosystem can participate in the ecological cycle, so that every member of them, even the consumer, is a producer.


    For example, if you want to put in birds, as consumers in the ecosystem, the food that birds need is mainly insects, then you need to put in insects to meet the consumption needs of birds. Birds themselves are producers, and their corpses and feces can be fed back to the whole ecological environment.


    Insects, on the other hand, mainly feed on plants. In the past, we tried our best to control and kill all kinds of insects, which is not a good thing for the ecological cycle. Therefore, I suggest Comrade Chen pay more attention to this aspect, and focus on control as much as possible. It''s impossible to lose any link in the food chain. "


    Hearing what Professor Li said, Chen Xin felt more cautious about this matter, so he nodded, recorded what Professor Li said, and made a mark.


    After talking about this topic, Chen Xin also asked Professor Li, "Professor, do you think it''s appropriate to open pet raising in the future Dome City?"


    "If you ask me this question from the perspective of ecological environment, I can only say that pets can also be regarded as a member of the urban ecological environment. Although the impact on the urban ecological environment is not too great, if there are pets in a city, we still need to seriously consider their impact." At this point, Professor Li seems to be a little tired.


    Chen Xin didn''t go on talking about it. He just said some polite things to Professor Li, such as having a good rest, and then left.


    Through a conversation with Professor Li, Chen Xin understood that the construction of ecological environment is not to simply add some species, but to artificially gather them together.


    If we want to build a balanced ecosystem, we need to consider the relationship between each species and other species in the whole system, in order to achieve the ideal state that all species can coexist.


    So it''s better to leave this matter to more professional people to study. Before they come up with a feasible scheme and verify its feasibility, it''s better not to mess about.

 Chapter 625

    In a city with a dome, insects are flying all over the sky. They are constantly gnawing at the leaves of the plants, making the original environment full of vitality become broken and desolate.


    A large number of insects are rampant, and even other animals are unable to withstand such a terrible disaster. The streets are full of dead animals, and their bodies are also eaten by insects, and even become a hotbed for hatching new insects.


    "Failed again!" Chen Xin, who saw this scene, could not help sighing, and the researchers who saw this scene with him became very depressed.


    "It''s really hard to build a stable ecosystem artificially!" A researcher could not help but abandon himself and almost lost the confidence to continue.


    This is the 17th time that they failed. Although this time the whole ecosystem persisted longer than any previous test, the whole ecosystem collapsed because of the gradual death of birds and the almost exponential reproduction of insects.


    Before that, the 16 attempts they made also ended in failure.


    For the first time, because the species of plants were not well controlled, insects produced toxins after eating the leaves of plants, poisoned birds and their corpses, and then indirectly poisoned other animals, resulting in the collapse of the whole ecosystem.


    The second time, although we noticed the problem of plant species, the number of birds in the city was unbalanced due to the hunting of pet cats. In the end, you still led to a flood of insects and the collapse of the whole ecosystem.


    The third is a surge in the number of birds, eating up all the insects; The fourth time, the predatory birds were put in to maintain the balance. As a result, the common birds were killed because of the territory problem; For the fifth time


    Looking at the experimental records, Chen Xinfan did not want to recall how he had failed before.


    In all the 17 experiments, they only insisted on the shortest ecosystem for seven months, and the longest one was this one. Although it lasted for 10 years, it finally collapsed.


    "What''s the problem? We have fully considered the demand and output of all animals in the whole food chain. Why do we still collapse? " A researcher is unwilling to question, as if he is questioning other people, as well as himself.


    Facing this problem, Chen Xin sighed helplessly: "the ecological balance itself is very fragile. Any variable can easily break the original balance. It takes a long time for nature to form a stable coexistence relationship to form a stable structure.


    The idea that we are now trying to artificially bring together several organisms to build a balanced and stable ecosystem is really idealistic. "


    Although Chen Xin doesn''t think this is impossible, after so many failures, even he has to admit that a truly stable ecological environment is far from being formed by adding several kinds of organisms.


    Perhaps there is a natural enemy relationship between the two species, but the effect of population number, environmental carrying capacity and other environmental factors often leads to the result is not as ideal as expected, and the difference between the theoretical result and the actual result may be just a little variable, which will lead to the difference between the two.


    "Are we thinking the wrong way?" Although seventeen consecutive failures frustrated everyone, some researchers still put forward new ideas: "in our previous experiments, animals were put in at one time. As a result, due to the different reproduction speed, the development speed between populations was different. As a result, a balanced ecosystem could not be formed, and the ecosystem soon collapsed every time.


    This time, we tried to propagate the species to a certain scale, and then put them in batches. The whole ecosystem collapsed in ten years, which lasted longer than every time before. So should we adjust our thinking? "


    "It''s reasonable for you to say that ecological balance should be a kind of dynamic balance. There should be some flexibility in the number of different populations, so that the whole ecosystem has a certain fault tolerance rate and automatic correction function. Maybe we should really change our thinking." Chen Xin listened to the researcher''s words and nodded in agreement.


    Their previous experiments mainly relied on Professor Li''s successful experience in studying the ecological agriculture system, combining several coexisting animals and plants according to the consumption and supply relationship in the food chain, in order to build a balanced ecological system.


    But it is clear that the ecosystem is not simply composed of several species.


    In particular, the changes of environmental factors will affect the ecology of species, and there is a relationship of mutual influence between different species.


    In this case, there are quite a few variables that affect the final ecological balance. Although Chen Xin can simulate the impact of various environmental variables here, he can''t calculate a correct answer.


    In other words, there are correct answers, but the conditions they provide are not enough to calculate the optimal solution.


    In the face of such a situation and seventeen consecutive experimental failures, it is also a good choice to change ideas.


    "It seems that we have overlooked another important factor." At this time, a researcher is trying to repeat the test just now. Just looking at the result, he suddenly found a blind spot.


    Hearing what the researcher said, Chen Xin looked at him curiously: "what did you find?"


    "What we need to build is an urban ecosystem, right? But so far, it seems that we have not taken the city as a variable into the whole ecosystem! And all we have been simulating is the ecology of animals and plants, not the existence of human beings. " The researcher spoke out about his findings.


    "That''s right, but we can''t build a stable ecosystem without considering cities and human activities. If human activities and cities are added as influence variables, it will be more difficult to achieve a balance." Although other researchers agree with his findings, they do not agree with his ideas.


    Chen Xin has some different views on this. He interrupted the debate between the two researchers and thought about it for a while. He said: "since we want to change our thinking, it is a way to add urban variables and human activities into the ecosystem as a reference. After all, this is the result we want. Now it is a better way to calculate, isn''t it?


    Moreover, what we should consider more than that is how to build this system first, so that it can run smoothly, instead of being destroyed for various reasons like now. "

 Chapter 626

    The failure of the ecological environment experiment really frustrated many researchers and Chen Xin, but it was just a dozen times of experiment failure, which did not make people lose their fighting spirit.


    In addition, they always lead to the collapse of the whole ecosystem when they only join animals. If they are only plants, they can make the whole ecosystem maintain a relatively stable state for at least 500 years.


    This also proves that the construction of artificial ecosystem is feasible, but compared with the situation that plants are relatively stable and controllable, animals are relatively more prone to change, which leads to the imbalance of ecosystem and eventually leads to ecological collapse.


    Chen Xin''s initial idea was to add animals to this relatively stable plant only ecosystem, but previous experiments have proved that this is not feasible.


    The failure of the first few experiments is largely due to the mismatch between plants and animals, which makes them unable to coexist.


    In the following experiments, they tried to put animals and plants together in the experiment, but the differences in reproduction speed between different species can easily lead to the collapse of the whole ecosystem.


    This is why, after the failure of the 17th experiment, some people proposed to change their thinking.


    Because according to the original idea, they have tried all the schemes they can try, and it has been proved that they must jump out of their original idea.


    So after the 17th experiment, Chen Xin gave everyone a day off to have a rest and change their minds to see if they could produce some new ideas.


    And he also tried to adjust his thinking, thinking about the problem.


    An ecosystem is generally composed of four parts: abiotic environment, producer, consumer and decomposer. In order to maintain the operation of an ecosystem, these four parts are indispensable.


    In Chen Xin''s current experiments, the abiotic environment is the best guarantee, and it is also the most stable part of the four parts.


    As for producers, they usually refer to the green plant part. Although this part is not as stable as the abiotic environment, it does not need to worry too much. They can already build a stable plant ecosystem.


    However, the consumer part of the whole system really baffles Chen Xin and the researchers.


    By definition, animals are consumers in the ecosystem, but in fact, every link in the whole food chain can be regarded as producers and consumers.


    They consume the next level, and they will be consumed by the upper level of the food chain. Finally, the existence at the top of the food chain will be decomposed by the decomposer after death, forming a closed loop of the whole material cycle and energy flow.


    Therefore, the supply and demand relationship between each species and other species is the key to maintain the balance of the whole ecosystem.


    This is just like a production line, where raw materials are imported from the source, and the processing workshop processes the raw materials into parts, and then assembles them in the assembly workshop. The amount of work to be done in each link is calculated in advance.


    If one of the links is more or less, it will lead to problems in the whole production line.


    More will lead to more things piled up in a certain link, and less will lead to less final products of the production line.


    It''s just that the production line in the factory can be adjusted directly, but the ecological environment is obviously not so easy to control and adjust.


    Although human beings can indeed play a regulatory role in the ecological environment of the Dome City, so that the entire ecological environment can persist for a longer time, if the ecosystem itself has problems, even if there is external interference, it will only operate for a period of time and eventually collapse.


    And there are problems in some aspects, even external intervention is difficult to save the whole ecosystem.


    This point can be clearly seen in the previous 16th and 17th experiments. The massive reproduction of insects creates a terrible scene like locust plague. Even if human intervention is involved, the final result is that the entire ecosystem must be rebuilt.


    Of course, the result is that the whole ecosystem has been out of balance without external intervention.


    If there is a monitoring system that can monitor the whole ecological environment all the time and deal with the problems and variables in time when they are found, it can indeed maintain the operation of the whole ecological system to a certain extent.


    As long as the problems that lead to the collapse of the whole ecosystem don''t happen in a moment, it can make the whole ecosystem run smoothly for a long time.


    But Dome City can do this, but later if you want to restore the ecology of the whole blue star, it will not.


    After all, human beings do not have such a strong power to monitor the ecology of the whole blue star, and timely adjust the possible problems.


    Therefore, Chen Xin must find a way to make the whole ecosystem run smoothly without external interference.


    But it''s not easy?


    Giving up thinking about this problem, Chen Xin decided to let his brain rest for a while and change his brain to see if he could have new inspiration.


    So he left the research center and went back to his home.


    Back home, Chen Xin noticed that Qin Lan was sitting on the sofa sorting out something, so he went over curiously and asked her, "what are you looking at?"


    "Some photos. Among the things that Qing Yan brought back before, there are many photos of the past, so put them in order." Qin LAN answers Chen Xin''s question and looks up at him: "why did you come back so early today?"


    "I met some obstacles in my work, and the experiment failed again, so I just gave everyone a day off to let everyone have a rest and change their minds." Chen Xin said so, sat down beside Qin LAN, picked up her album and turned it up.


    Most of the photos above are of them playing in Mo Qingyan''s bar before, and some of them were taken when we went outdoors together.


    Looking at these photos, Chen Xinfan recalled the happy times in the past and felt relaxed for a while.


    However, when Chen Xin was looking through these photos, he suddenly noticed that one of them was different.


    Qin Lan was photographed in the photo, but she was totally different from Chen Xin, who always made training clothes. Instead, she wore a long plain white dress and sat quietly in front of a table. In front of her, there was a glass ball like a fish tank with stones and small fish and algae.


    Chen Xin''s eyes are really attracted by the glass ball. He asked Qin LAN curiously, "a LAN, when did you take this picture? And what is this ball? If you don''t open your mouth, won''t the fish suffocate? "


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 627

    The glass ball in Qin Lan''s photo is called ecosphere, which is a popular small fresh decoration before the disaster.


    The method is also very simple, just find a transparent glass container, lay a layer of fine sand in it, fill about two-thirds of the water, then put in small fish and shrimp, and seal the whole container.


    The ecosphere created in this way can maintain the ecological balance for about two months. Although it needs to be exposed to the sun every day to ensure the light, and the proportion of small fish, shrimp and algae should be well controlled, generally speaking, it is only such a simple thing that can maintain the ecological balance for two months, which is of great research significance.


    In fact, after the ecosphere was first invented by two scientists, it has always been a very meaningful research project.


    If the ecosphere is compared to a small blue star, the little red shrimp represents human beings.


    So this ecosphere can lead to today''s blue star. The natural ecological environment is constantly damaged. If it continues to be damaged and not improved, all life may be threatened by death.


    The idea of the ecosphere just reminds us of the importance of maintaining ecological balance to life. It also reminds us of the chain relationship and the mystery of all kinds of creatures on the blue star.


    At the same time, before the disaster, space research institutions are also carrying out research on the ecosphere, in order to build such a balanced ecological environment with spaceships or space stations and outer space colonies as containers to ensure the survival of human beings.


    This coincides with Chen Xin''s current purpose and can also provide him with a lot of reference.


    "I used to see this kind of small ecosphere in Qingyan''s bar. Do you care about it, Xin?" Qin LAN sees that Chen Xin is very concerned about ecosphere, so she asks curiously.


    Although she is together every day, Qin Lan''s main job is to assist in the development and design of Titan. In addition, she is not the kind of person who likes to ask Chen Xin what he is doing every day, so she doesn''t know Chen Xin''s work very well. She just knows what he is doing.


    Chen Xin nodded and explained to Qin LAN: "recently, we are studying the ecosystem. This ecosphere is of great reference significance."


    "Is ecosystem the ecological cycle in biology textbooks before?" Qin LAN can be admitted to the civil service and become a special police officer. Of course, she can''t be a scum. She still knows what these middle school students have learned.


    "It''s the ecosystem. Now the natural ecosystem has collapsed, so I plan to build an artificial ecosystem. But so far, it''s difficult to maintain its balance and existence. It always collapses after a few years. It''s not as stable as this kind of ecosystem." The bitter smile on Chen Xin''s face is not that he belittles himself, but that the real artificial ecology is not as stable as the ecosphere.


    Although a simple and small ecosphere like this may not work in two or three months, if it is well controlled, an Ecosphere can last for more than two to three years, or even five to seven years for larger ones, and the longest can last for more than ten years.


    This is obviously more stable than Chen Xin''s ecosystem.


    Of course, this is mainly because of the difference in complexity between the two. After all, the internal environment of the ecosphere is very simple, the number of species is small, and the natural variables that affect the balance are also small. It is not particularly difficult to maintain the balance.


    After all, there are only algae and small fish and shrimp in it, and only light and temperature can affect its ecological balance. Controlling these two variables well is enough to ensure the ecological balance in the ecosphere until the life of algae or small fish and shrimp is exhausted.


    As for reproduction, it is impossible. The space of such an Ecosphere is very limited, which does not support the reproduction of small fish and shrimp or the increase of algae.


    The replacement of a larger space can improve this.


    Thinking of this, Chen Yu suddenly felt that he could try another way.


    He stood up excitedly, took Qin LAN and gave her a kiss on the face, then rushed to the holographic image room.


    Qin LAN looks at Chen Xinyi in a hurry. Although she is puzzled, she also feels helpless, but she still smiles and doesn''t care. She continues to sort out the photos in front of her.


    Chen Xin, who rushed to the hologram room, put his new ideas into an instrument built with nano molecules on a watch, and then projected them in the hologram room.


    This time, Chen Xin did not use the method of adding everything at the beginning to build the ecosystem, nor did he use only plants to build the ecosystem, or even directly use the Dome City as the basic environment. Instead, he chose a kind of plant and an animal, like an Ecosphere. He only delineated a small space and put two species in.


    In addition, all Chen Xin provides for this "ecosphere" is soil, light and enough water resources.


    Chen Xin''s plant is just the most common grass, and the animal is rabbit.


    Rabbits eat grass, then excrete faeces, which are decomposed by bacteria and absorbed by grass again as nutrients to supply grass growth, thus forming a cycle. If there is no problem, it should be a stable system.


    Of course, if the number of rabbits increases beyond the environmental carrying capacity, it will undoubtedly lead to the collapse of the whole ecosystem.


    However, this is only a simulation experiment. Chen Xin only allowed rabbits to reproduce moderately and maintain the population size, but did not allow them to reproduce unrestricted.


    After all, Chen Xin is very clear about the terrible consequences of rabbit overbreeding.


    Because the number of rabbits is artificially controlled, this cycle has not been broken. After the number of rabbits reaches the upper limit of the environment''s carrying capacity, it will be stable, and it can continue to cycle according to the program.


    Chen Xin is not surprised by this result, because quite a lot of other variables are ignored. The whole cycle is just a simple simulation test, and there is no ecosystem to speak of. In addition, Chen Xin is also adjusting artificially. If this can collapse, then there is no need to play.


    With this initial foundation, Chen Xin can carry out further tests.


    That is to say, instead of artificially controlling the number of rabbit population, we put predators into it and control the number of rabbits by predators themselves.


    Of course, with the addition of predators, the size of the "ecosphere" becomes narrower. Therefore, while investing in predators, Chen Xin also enlarges the size of the whole "ecosphere", improving the environmental carrying capacity and the upper limit of environmental carrying capacity.


    As for Chen Xin''s predators in the ecosphere, he chose the same common wolf.


    Rabbits eat grass and wolves eat rabbits. In the end, the carcasses and excrement of wolves and rabbits will be decomposed and return to the earth to become nutrients of grass. In this way, the cycle will be formed.

 Chapter 628

    When Qin LAN and Mo Qingyan were worried about finding the holographic projection room, Chen Xin''s experiment had reached a new stage.


    The "ecosphere" in front of him is no longer the state of the region and a few species at the beginning, but a large island with prosperous species.


    On the island, all kinds of creatures are full of vitality, and different species maintain a balanced symbiotic relationship. Although it is not the harmonious coexistence mentioned in some novels, the relationship between different species is stable, and no one species threatens the survival of other species, so it is possible to break the ecological balance.


    Qin LAN and Mo Qingyan already know what Chen Xin is doing recently, so they don''t find it strange to see this scene full of vitality. However, the beautiful scene of harmonious coexistence of creatures still makes them unconsciously exclaim.


    "Ah Xin, did you make this? How beautiful the island is Mo Qingyan takes the lead in praising that the island is really beautiful in front of her eyes, which is no worse than the tourist attractions she has been to.


    Although Qin LAN didn''t say anything, she could see from her eyes that she liked the scenery very much.


    Chen Xin didn''t have any special feeling about this. He just laughed at them: "this is my ongoing experiment of constructing an ecosystem. At present, my idea is right. The ecosystem of this island has been stable for 400 years. If there is no influence of external factors, it can continue to exist stably."


    This island is the result of Chen Xin''s increasing species in the previous "ecosphere".


    This time, Chen Xin''s strategy is to first build a stable ecological cycle, and then gradually add new links and chains in this cycle, so as to expand the size of "ecosphere" in a stable way.


    From rabbits and grass at the beginning, to today''s Island, although not complex, has a wide range of ecological systems. This experiment is very smooth.


    Although there was ecological imbalance due to the addition of new species by Chen Xin in the middle of the experiment, with the increase of species and space in the whole ecosystem, the whole ecosystem also has a certain ability of regulation. In this experiment, although there were several ecological imbalances, the balance was finally restored by the ability of regulation of the ecosystem itself.


    This also surprised Chen Xin. After all, in the previous experiment, once the ecosystem was out of balance, without external intervention, the whole ecosystem would collapse directly.


    This result also makes Chen Xin reflect on what they have neglected in the previous experiment, which makes the whole ecosystem so fragile.


    While Chen Xin is thinking about these problems, Qin LAN and Mo Qingyan are curiously observing the island built by Chen Xin.


    The whole island area is not too large. There is a small basin surrounded by a circular mountain range and a bay formed at the gap of the mountain range. There is a fresh water lake in the center of the basin. On the outside of the mountain range are the same beaches as the Bay, as well as reefs and cliffs. On the inside of the mountain range are dense virgin forests.


    It can be said that the terrain of the whole island is very complete, so it is difficult to find such a suitable terrain environment for a variety of organisms in nature.


    However, this island was artificially created by Chen Xin for the purpose of experiment. It is not surprising that it has all kinds of terrain and is suitable for all kinds of creatures.


    "Is there no one on this island?" Looking at the panoramic view of the whole island, Qin LAN suddenly asked Chen Xin strangely, "ah Xin, do you want to build a dome city ecology? If it''s just an island, isn''t it enough? "


    For Qin Lan''s question, Chen Xin nodded and explained to her, "there is no human activity on the island for the time being. That''s the content of the next experiment. After all, the damage and impact of human activities on the ecology is too great. I must consider all the influencing factors before putting human activities into the whole ecosystem. "


    Qin LAN and Mo Qingyan obviously know little about this. They can understand what Chen Xin is saying, but it is difficult to understand the specific meaning of his words.


    Fortunately, they didn''t like to study deeply. They didn''t ask much. They just stayed by Chen Xin''s side quietly, enjoying the beautiful scenery of the island in front of them, accompanying Chen Xin and watching him continue to work.


    Chen Xin has never affected his working state because of two more people around him. He is still very focused on observing the changes of the whole ecological environment.


    However, the island''s ecology has stabilized. Without variables, it will not break the balance due to its own internal reasons.


    Seeing this, Chen Xin finally put in a new variable, human beings, to the island.


    However, Chen Xin obviously did not add cities to the island at the very beginning, nor did he invest in modern science and technology. Instead, he just launched a sailing boat equivalent to human science and technology in the era of great navigation before the first industrial revolution, so that the sailors came to the island as survivors of shipwrecks.


    Due to the small number of human beings and backward science and technology, this boat has not had a great impact on the island. Even with the passage of time, their impact on the island ecology has been gradually eliminated.


    It seems that human beings have become a part of the island ecosystem and participated in the ecological cycle.


    For such a situation, although Chen Xin had some expectations, he still felt a bit surprised.


    It has to be said that the development of human civilization and science and technology has seriously damaged the environment, and with the growth of human population, the pressure on the ecological environment is also increasing day by day.


    Only in this way can the impact of human beings on the environment be limited to the minimum when human science and technology are not very developed.


    Just like the human beings on this island, their demands for the environment are only limited to their own survival, and they are also within the range of the whole island environment.


    So they can integrate into the island''s ecosystem, and not become a variable that destroys the island''s ecology.


    Chen Xin is very satisfied with this. Although this is only a simulated state, the experimental results can still provide great reference value for his ongoing experiments.


    As for the impact of the development of human science and technology on the environment, this is not too difficult to solve in Chen Xin''s view.


    After all, the reason why human beings caused so much damage to the environment in the past is largely because human beings did not realize this problem and did not pay attention to it. When human beings recognize and begin to pay attention to environmental problems, it is difficult for human beings to cause such large-scale damage to the natural environment.

 Chapter 629

    Finally, Chen Xin proved through experiments that the period of the two industrial revolutions was the period of the most serious damage to the natural environment.


    At the beginning, when human beings landed on Shanghai Island as a variable, it did have a certain impact on the island''s ecology. However, due to the small number of human beings, the island''s ecological carrying capacity can carry the needs of human survival, so the ecological balance has not been damaged.


    Although part of the ecological environment has been damaged, the whole is still balanced.


    However, as Chen Xin released the restrictions on human science and technology and gradually upgraded the level of human science and technology, the damage to the environment became more and more serious.


    During the first industrial revolution, in order to drive the steam engine, people cut down trees and dig coal under the stratum, which caused great damage to the ecological environment; During the second industrial revolution, the rise of petroleum and chemical industry directly polluted the whole ecosystem.


    If Chen Xin didn''t start to introduce his own upgraded new energy technology at the end, which curbed the damage of human beings to the environment, I''m afraid that this "ecosphere" experiment will eventually fail because of the collapse of ecological balance, just like the previous 17 experiments.


    Of course, this is just an experiment.


    Although human beings did do these things in history and did cause great damage to the ecology of Bluestar, it is not inevitable.


    Or in other words, human development does not have to be based on the destruction of the environment.


    After Chen Xin traced back the time of "ecosphere", reintroduced human science and technology, and modified human behavior pattern to care for the environment, human damage to the environment immediately reduced a lot, and even gradually reduced to the extent that the environment can bear with the improvement of science and technology.


    Although this is a very ideal state, it proves Chen Xin''s idea and provides important data support for him to build the ecological environment of the dome city.


    Qin LAN and Mo Qingyan don''t have any feeling or understanding about it, but it''s very uncomfortable for them to watch the beautiful island become ugly under the over development of human beings.


    It has nothing to do with whether they know that this is the history of human development, or whether they are environmentalists. Anyone with a normal aesthetic is unlikely to like the cross flow of sewage, and the sky is full of black clouds, acid rain and toxic air brought by pollution.


    So they were happy to see that Chen Xin retraced the whole experiment, reintroduced human beings, and obtained completely different results.


    "Ah Xin, did you modify something?" Although Mo Qingyan can''t see why the results are different, she can still understand that there must be some adjustments made by Chen Xin: "so, your experiment should be successful?"


    Chen Xin smiles and nods. After exporting and saving the existing experimental data, he restarts the "ecosphere" and replies to the two: "I have found a way. Although I can''t guarantee the success of the experiment, I have at least 70% confidence in success."


    Hearing Chen Xin say so, Qin Lan also gently nodded to him and said with concern: "since the experiment is successful, go to bed early. You''ve been busy all day. It''s time to go to bed early."


    Finish saying, saw Mo Qing Yan one eye, two people eyes revealed the same vision.


    So they stood up at the same time, one on the left and the other on the right, took Chen Xin''s arm and put him out of the holographic imaging room.


    "Well? What are you doing? Wait, I haven''t verified the experimental results yet! Wait a minute! Let me turn off the machine! Ah LAN! Qing Yan! Put me down Chen Xin intends to break free, but Qin LAN and Mo Qingyan are very determined and put him back in the bedroom.


    There was nothing to say all night, but when he got up the next morning, Chen Xin had a withered face.


    "I''m so stupid, I only know that women are tigers, but I don''t know that two women are more terrible than tigers..." at this time, Chen Xinyi looks like Xianglin''s sister-in-law, his eyes are blankly talking, and his two beautiful bodies are sleeping.


    Quite a bit trembling to get up from the bed, went to the bathroom to wash clean, and took a shower, Chen Xin this just slightly recovered a bit.


    The two goblins on the bed who beat him to the marrow last night finally woke up. Looking at Chen Xinyi''s appearance of being squeezed dry, they couldn''t help laughing together.


    It''s just that there is a sense of shyness and competition in the smile.


    Although they have reached an agreement and are willing to live in harmony, Qin LAN and Mo Qingyan still need to compete on some things.


    It''s like Qin Lan''s gesture to Mo Qingyan at this time. After Mo Qingyan returns to her for a four, Qin Lan''s face suddenly changes. Then she gets up from the bed unconvinced and rushes directly into the bathroom even though Chen Xin is still taking a shower.


    "Alan, what are you doing in the morning?" Listening to Chen Xin''s exclamation in the bathroom, Mo Qingyan''s face is a little bit hot and dry, burying her scarlet cheek in the pillow.


    Just listen to the voice from the bathroom, her face is more shy, and finally she can''t bear it. She also rushes into the bathroom to continue the unfinished competition with Qin LAN last night.


    For Chen Xin, it''s really enviable to get up in the morning and be treated like this, but it''s really a heavy burden.


    Even if Chen Xin''s health is really good, he can''t stand such pressure.


    Finally, he had to ask for a day off, had a good rest in the office for a day, and asked the canteen to prepare some nutritious food for him before he recovered.


    As for the experiment that should have been carried out, it didn''t affect much, but Chen Xin didn''t use the holographic imaging room at home. Instead, he used nano molecules to project a pair of VR glasses in the office and made do with the experiment.


    This time, Chen Xin adjusted his thinking. He did not invest in all species from the beginning, nor did he deliberately calculate the symbiotic relationship between species. Instead, he first built a dome city as a basic environment, and then put in only the most basic consumers and producers, just like making an ecological ball, to make the ecological cycle work, Then gradually add a variety of species that have been checked before, and let them develop freely. Until the ecological environment is stable, the next species will be added.


    Compared with the scheme used in their previous experiments, this method undoubtedly lengthened the time for the formation of the whole ecological environment, but it was also relatively stable. After Chen Xin spent a day putting all the species in, the ecology of the whole simulated Dome City was still very stable, and there was no ecological imbalance.

 Chapter 630

    Through experiments, Chen Xin has obviously found a correct way to build an ecosystem.


    First, build a more stable ecological cycle, and then add new species to it, stimulate the original species with new species, make them change, accommodate new species, and form a new ecological cycle. After such repetition, we can finally get a stable ecosystem.


    In fact, this approach is to use the adaptability of organisms to force them to make changes in order to adapt to the environment.


    In the natural environment, in order to survive better, animals and plants often take the initiative to adjust themselves to adapt to the environment, and when the environment changes, they will often not adapt to the situation.


    If given some time, adaptive organisms can gradually adjust themselves to adapt to the environment, and finally survive.


    Darwin''s theory of biological evolution comes from this. In the process of constant adaptation to the environment for hundreds of millions of years, organisms develop and evolve into different forms and new species. In the final analysis, all organisms themselves can be traced back to the origin of life. It is only the evolution of hundreds of millions of years that makes them different.


    The reason why Chen Xin''s previous experiment of building a dome city ecosystem has been failing continuously is that they directly knead different species together and did not consider the adaptation process of species to the environment.


    In fact, it''s no wonder that Chen Xin didn''t give the species time to adapt, because it''s not an actual operation, it''s just a simulation through a virtual device.


    All kinds of data of species and fitness among different species are written in advance. They are pieced together and calculated according to the preset variables. Although there are adaptive variables among species, these variables need time to adapt and adjust just like the real biological evolution.


    The biological adaptability of species can not be achieved by one or two generations of iteration. After all, the organisms in nature usually do not have such exaggerated speed of variation and evolution, and the adaptability of species is not so strong.


    But Chen Xin''s experiment is different.


    Although there is not much change on the whole, it is just to build a stable cycle first, and then add new variables continuously.


    But the key is that every time Chen Xin adds a variable, he will wait for the whole ecological cycle to stabilize before adding a new variable, which gives the species time to adapt.


    In short, every time Chen Xin joins a new species, he gives the original species time to adapt and evolve.


    It is precisely because of the time to adapt that the whole ecosystem can adjust itself to accommodate more species and build a more stable ecological environment.


    However, for the ecological environment construction of Dome City, it can only be regarded as a reference value, and can not be constructed in this way.


    After all, the construction period of the whole Dome City is about one year. With one to two years of follow-up work, the whole city will be completed in three years. It is impossible to spend two or three hundred years slowly waiting for the ecological environment to be stable.


    However, this does not have a great impact on Chen Xin. Through virtual simulation experiments, we can condense hundreds of years into a few hours, and get a result Chen Xin wants through a large number of experiments.


    Before the construction of the dome city ecosystem, the main problem is that after the species population reproduction, it is easy to cause the ecological imbalance due to the over reproduction of one species or the conflict between two species.


    But now that Chen Xin has sorted out his ideas again, he can select the right species combination through many simulation experiments, and test the most suitable construction method with the help of simulation experiments.


    Chen Xin thinks so and does so.


    In the virtual space, ten domes have been unfolded, and all the basic conditions are based on the real situation.


    It''s just that the basic ecological construction and the species to be put into each dome are different.


    This time, Chen Xin hopes to find out how to stabilize the species combination in a short time through the test, so as to build a stable ecological environment in the Dome City in a short time.


    For this ecological environment, Chen Xin has lowered his requirements. He does not require how complex the ecological environment is, or how many species there are, but hopes that the whole ecological environment can be built in a short time and stable enough.


    According to Chen Xinxin''s previous ideas, there are some problems in his thinking. It is unrealistic to directly build a complete ecology.


    The maladjustment and conflict between species in a short period of time can completely destroy the balance of the whole ecosystem. Only when the species adapt to each other can the balance of the whole ecosystem be maintained and new species be accommodated.


    First, build a simple ecological cycle in a short time, and then add new species to the ecological cycle continuously for a long time, so that the whole ecological cycle will eventually become rich and diverse, turning the original short-term plan into a long-term project.


    This will certainly make the construction of the whole ecosystem take a long time, but it is not a long time for the self-regulation of the ecological environment and the adaptation of species.


    This time, the experimental results also verified his conjecture.


    Ten domes, in the initial foundation of ecological construction, only three domes have problems, the other seven have successfully established a stable ecological environment.


    As for the three domes that have gone wrong, they have not fallen into ecological collapse, but can be adjusted by human external forces to restore ecological balance.


    This makes Chen Xin very happy and full of confidence in the success of this plan.


    He tweaked the details of several domes, adding new species to them, as well as the most critical human activity.


    His own "ecosphere" experiment has accumulated enough human activity data for him, and now it is substituted into the dome ecosphere experiment, which undoubtedly makes this experiment more valuable and authentic.


    The impact of human activities on the ecological environment can be fully verified in Chen Xin''s experiment.


    After all, what he wants is an urban ecology, rather than simply building an ecological environment apart from human beings.


    After Chen Xin added these parameters and variables, with the passage of time in the virtual space, different ecological environments evolved in the ten domes, giving different results.


    Finally, after the 100 years set by Chen Xin, the environment in the ten domes has undergone earth shaking changes, and Chen Xin has also obtained the answer he wants.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 631

    Ten experimental domes have lasted for 100 years, and only three have really completed the construction of ecological system.


    The other seven ecological domes, some plants grow wantonly, have lost the trace of animals, and even cover the whole city without human intervention; Some are due to the flooding of some animals. As in previous experiments, the ecological balance collapses and all living things become extinct and desert; Some are half dead because of the influence of human activities, and the whole ecology is in danger


    But in addition, the three dome cities, which can survive for 100 years and maintain ecological balance, have achieved the experimental goal perfectly.


    In these three domes, there is not only a stable ecological environment, but also a harmonious relationship between human activities and ecological environment, and human activities have become a part of the whole ecological environment.


    Not only that, the species are prosperous, the biological population is full of vigor and vitality, the whole ecosystem is stable and balanced, and can accommodate new species at any time, which can be said to be the most ideal result.


    After deriving these three results, Chen Xin finally took a breath.


    This experiment can finally be ended, and all the previous efforts are finally meaningful.


    It is undoubtedly very satisfying to be able to get such a result. Although it is said that even if the ecological dome is just a little greenery, and some animals can also be raised casually, Chen Xin obviously does not want such a result.


    In fact, from the beginning, Chen Xin had such a choice. He could provide animals and plants for the Dome City, which could be some common species. He built the Dome City as a park or greenhouse. As long as the animals and plants can be filled in, whether it can form an ecological balance and build a balanced and stable ecosystem does not need Chen Xin to consider.


    But for Chen Xin, if the result is like that, it will be meaningless for him.


    What he wants is an ecological environment in which human beings and other creatures live in harmony with nature, so that after the weather controller is upgraded to a planet reformer and the blue star climate is reversed, the blue star ecology can be rebuilt, not just for a city to do some greening and raise animals.


    So even though he has spent a lot of effort and energy and failed many times, Chen Xin still pursues the answer and result to build the ecological environment he wants.


    Fortunately, Chen Xin got the answer he wanted and found a way to build a harmonious urban ecology.


    Chen Xin left the research center after he derived the three experimental results and gave them to other researchers to deduce a scheme based on the three experimental results.


    Instead of going home, he went to the weapons laboratory where he was doing research on mecha and Titan.


    Here, a new Titan is being tested and studied.


    This Titan and other titans have a very different shape and appearance.


    If the ordinary Titan looks like a technological creation, with rough shape and metallic design, then this Titan is more like a mythical creation, with more delicate and delicate design. Although the appearance also has a metallic sense, it has more sense of future.


    To make an analogy, ordinary Titan is a hardline science fiction painting style, while this Titan is full of that super series of decorative style.


    What''s more, this Titan is really equipped with those fantasy style and super series melee weapons. At this time, this Titan is holding a long knife to chop the armor plate for testing.


    Watching the Titan split the armor plate equivalent to the main armor of the main battle tank, Chen Xin went forward and asked the researcher who was doing the test: "how about the performance of this body?"


    "It''s amazing. It''s completely superior to our existing body. Both the output power of the body and the output power of the core are several times more than those of the existing body, and the material of the body is better than what we use now! The shield it carries can even withstand the direct attack of the main battle tank''s close range armor piercing bullet. It''s incredible The researcher''s face was full of excitement, and he was obviously shocked by the Titan''s performance.


    Naturally, this Titan was not made by these researchers, but was upgraded by Chen Xin using his original body.


    Originally, Chen Xin just wanted to realize his dream of driving GAODA, so he just rubbed out such a fantasy super system and planned to play occasionally, which was a relaxation for himself.


    Adhering to the principle that since he is his own toy, he should make his best design. Chen Xin applied some designs of fantasy body he had seen before, and named the body white dragon.


    In the design of the body''s shape and performance, Chen Xin also tried to rely on this as much as possible, in order to better reflect the theme of the white dragon.


    Even on the head of the machine, Chen Xin specially installed two antennas like dragon horns, and specially made the head of the machine into the shape of a dragon head. Many decorative dragon patterns were added to the surface of the machine.


    All this is to satisfy his dream of having a big toy.


    But Chen Xin did not expect that after the body was built, the researchers saw that the performance of the body was so powerful, so they pestered him to test the body.


    Chen Xin had no choice but to lend the body to them for research and testing, which can be regarded as providing technical support for the design and development of Titan project.


    I just don''t know how much I have gained after lending them this machine for so long.


    Thinking about this, Chen Xin asked the researcher, "have you finished the test? I want to drive it out. "


    "Today''s test has been done almost, academician Chen, you want to open completely no problem!" When the researcher heard Chen Xin say that he wanted to drive this valuable machine for a walk, he unexpectedly did not object. Instead, he said to him, "if you can, can you cooperate with us to complete the follow-up test project, academician Chen?"


    "What are the projects?" Chen Xin inevitably picked up the list of test items handed over by the researcher, glanced at it and then nodded: "OK, they are all outdoor test items, I can cooperate with them."


    After that, Chen Xin motioned the tester to stop the machine, and then sat in by himself. Chen Xin projected a driving helmet directly with nano molecules, held the joystick of the machine, and yelled: "white dragon Titan starts, driver Chen Xin, attack!"


    With the cry, which was quite second in the class, but not heard by others, Chen Xin pulled the control lever, activated the jet port on the back of the body, suspended the whole body, and rushed out of the test site in a nearly flying way.

 Chapter 632

    Chen Xin is not an excellent Titan driver. Although he said Titan was his invention, he belongs to a researcher. He only knows how to drive Titan, which is not up to the level of top ace driver.


    Even after receiving the training, Chen Xin, with the super body of the white dragon Titan, which is specially made for himself, just regards it as a big toy rather than a real super war machine.


    However, in Chen Xin''s view, the most suitable destination for the white dragon Titan is its own big toy, rather than being used as a war machine.


    After all, if we still need to send the white dragon Titan to the battlefield in the current environment, we can imagine what a terrible situation the human race will face.


    Fortunately, this Titan, named White Dragon by Chen Xin, only needs to be his toy. At most, it can be used by researchers for analysis and research, and there is no need to consider taking it to battle.


    This also allows Chen Xin to drive this super series Titan to his heart''s content and enjoy the pleasure of driving radish without considering other things.


    White dragon Titan, as a super body, has a performance far superior to that of ordinary Titans. Even its energy system is quite different.


    Ordinary Titans use isotopic batteries. Although they have strong output and can be used for a long time, they are far from the fusion reactor on white dragon Titans.


    This micro fusion reactor is naturally the product of the system upgrade. Its output power is 20 times that of isotope battery, which provides strong power for the white dragon Titan.


    With enough power, we can drive a bigger body and use some high energy consuming equipment.


    The flight thrusters, electromagnetic shooting weapons and high frequency vibration melee weapons that ordinary Titans don''t have are the standard configuration of white dragon Titan.


    Although these weapons are more decorative than practical in some sense, flight thrusters are very practical equipment.


    Through several main thrusters and more than 20 attitude control nozzles, the whole white dragon Titan can move at a high speed of 350 kmh, and can fly at low altitude in a short time.


    It''s obviously not up to standard for an aircraft, but it''s quite enough for a Titan.


    In particular, the white dragon Titan is 1.5 times as tall as the ordinary Titan and weighs more than 1.7 times.


    In addition to studying its materials, the previous analysis and testing of the white dragon Titan focused on this set of flight thrusters. They plan to integrate this set of devices into ordinary Titans after analyzing them, and develop a number of Titans with flight ability.


    Chen Xin naturally supported this, so he lent the white dragon Titan to those researchers for analysis and testing.


    Now, he drives the white dragon Titan himself. In addition to experiencing the pleasure of driving radishes, he also has the purpose of testing the white dragon Titan''s flight propulsion outdoors.


    That''s why Chen Xin directly started the jet port to let the white dragon Titan fly close to the ground and leave the scientific research center instead of coming out.


    The speed of 350kmh is quite terrible. Under normal circumstances, only high-speed railway and high-speed racing cars can reach such a speed on the ground, and this can only be achieved when both of them have special tracks and venues.


    So you can imagine what a terrible feeling it was when the white dragon Titan flew close to the ground at such a speed.


    If not for the fact that the ground is basically covered with snow and there are no obstacles, Chen Xin would not dare to raise the speed of the white dragon to this level.


    Although Chen Xin used nano molecules to project a driving suit and helmet for himself in time, with the help of the helmet to assist driving, the scene in front of him was still a great test of his reaction and judgment ability.


    This is also the difference between top racing drivers or pilots and ordinary people. In the case of extremely high speed, the object may not stay in the line of sight for even a second. The reaction time left to the driver is quite short.


    Ordinary people may have passed without reaction, but pilots or racing drivers need to respond and judge in time, and complete the operation, which is really a test of a person''s ability and quality.


    Although Chen Xin doesn''t have such excellent physical fitness, he can still control the white dragon Titan by relying on the driving suit and helmet projected by nano molecules with the assistance of helmet.


    According to the test requirements, a series of tests, such as linear acceleration, emergency stop, turning, speed change and so on, have been carried out, which can be said to give full play to the body performance of Bailong.


    It has to be said that the performance of the Super Series airframe upgraded by the system is really exaggerated. Even if it flies close to the ground at a high speed of 350 kmh, Bailong''s airframe can still respond quickly and complete all Chen Xin''s operations accurately.


    When flying close to the ground at a high speed of 350 kmh, even if it is 90 km in place ¡ã Turn, 180 ¡ã Turn around, or 360 ¡ã The white dragon has completed all the movements perfectly, but the body itself is still in good condition, it seems that it has not reached the limit of performance.


    It''s just a pity that Bailong may not have reached the limit of body performance, but Chen Xin has reached the limit of his body.


    After all, he is not a professional pilot and has never been trained. For Chen Xin, it is still too heavy a burden to carry out all kinds of exaggerated maneuvers at such a high speed.


    He had to finish these tests, the white dragon stopped, the whole person sitting in the driver''s seat panting to restore their state.


    350 kmh sharp turn, the G force is enough to make people have black vision and physical discomfort.


    Even professional pilots have to wear special anti-G suits and undergo strict professional training before they can stand it.


    However, even so, for pilots, this kind of high-speed mobility still has a great load on themselves, not to mention that Chen Xin is just an ordinary person with average physical quality.


    Fortunately, his driving suit took on part of the function and function of anti-G suit. After Chen Xin gasped for a while and took out a bottle of special energy drink from the storage compartment in the cockpit, he finally recovered.


    After the recovery, Chen Xin did not rush back.


    Now that the test has been finished, he finally drives the white dragon out. How can he have a good time.


    Although he can''t bear the pressure brought by Bailong at the highest speed, Chen Xin can still control it at a slightly lower speed.


    Insert the drink bottle into the net pocket beside the cockpit, push the lever with both hands, the huge body of the white dragon flies up again, and the air jet from the propeller blows up the snowflakes all over the sky.

 Chapter 633

    When Chen Xin got addicted and drove Bailong back to the research center, it was several hours later.


    Because I was flying at high speed just now, a thin ice shell formed on the surface of the whole aircraft because of the low temperature. When I returned to the scientific research center, the temperature rose suddenly, and the thin ice on the surface melted. Coupled with the heat generated by the aircraft itself, a layer of white water vapor rose up on the surface of the white dragon.


    With the distinctive shape of the white dragon, it''s like a cloud of white water vapor covering the surface of the body. It really makes the white dragon look like a Dragon God coming out of the clouds. It''s quite fairy and mysterious, and looks very handsome.


    Chen Xin opened the cockpit and jumped down. He turned his head and looked at the white dragon Titan. He felt his chin and muttered, "it really looks like a dragon. It''s cloudy and foggy. Next time, just install a smoke generator."


    "Do you really think of it as a toy?" Next to meet Chen Xin back Qin LAN heard him mutter, can''t help but ask.


    "Ah LAN? What are you doing here? " Hearing Qin Lan''s voice, Chen Xin turned and looked at her: "I made the white dragon to play by myself. It''s OK to add some special effects to increase the entertainment effect, isn''t it?"


    "Yes, in order to drive a robot, I specially built such a powerful body as a toy. It''s really nothing." Qin LAN did not have the good spirit to Chen Xin to return a sentence.


    It''s not that she deliberately turns against Chen Xin. She just looks at the huge performance gap between the test model she used and the white dragon Chen Xin made as a toy. Qin LAN is still a little tasty.


    Now, as a Titan pilot, although her technology is not the best, she is also a member of the first echelon of all Titan pilots in China.


    It is also because of Qin Lan''s superb driving skills that she was able to work as a Titan tester in the scientific research center to assist researchers in developing and testing the new Titan. At the same time, she was able to drive to the latest Titan developed in China.


    But even if the newly developed Titan is compared with Chen Xin''s own white dragon, the gap is still as big as the miscellaneous fish mass production machine and the protagonist''s special installation machine.


    In particular, just now Chen Xin drove the white dragon out to maximize the performance of the white dragon''s airframe. He carried out all kinds of maneuvers at a speed of 350 kmh, which was like driving a fighter.


    This makes Qin LAN especially envious in the heart, at the same time also can''t help some small taste, why oneself can''t open so fierce organism.


    Qin Lan''s emotion Chen Xin can naturally detect. Looking at her, she seems to be a little unhappy. Chen Xin takes off her helmet, scratches her head and asks her, "what''s the matter? So much sour? "


    "Nothing." Qin LAN is just a moment to eat, see Chen Xin asked himself, or quickly hide their emotions, but she still looked at the huge white dragon with a bit of envy, asked Chen Xin: "Xin, can I open this machine?"


    "What do you mean? No problem! Take it if you want! Anyway, I built this machine to play by myself. By the way, I lent it to them for analysis and testing. If you like it, it''s OK to drive it out to play. " For his girlfriend want to open the idea of white dragon, Chen Xin naturally not allow.


    He is not that kind of very unique character, even his own things to others are not willing to touch, since they have been lent to researchers for testing, Qin LAN want to open of course is OK.


    And he also noticed Qin Lan''s emotion, and understood what she meant.


    Now Qin LAN is a Titan pilot. With her character, it''s natural for her to want a better body.


    Chen Xin, who understands this, knows that it''s time to build an exclusive body for Qin LAN. However, he doesn''t show this idea, but plans to surprise her.


    So he just comforted Qin LAN and said that Qin LAN could drive the white dragon at will. Then he went to the researchers who had done the test before and asked them about the test of the white dragon.


    "The performance of Bailong is excellent! Both the mobility and the carrying capacity of the body are excellent! If it is air combat, its performance is better than that of active fighters in low altitude environment! " The researcher was obviously very satisfied with Bai Long and was very excited when answering Chen Xin''s question.


    Although the white dragon has been lent to them for research for some time, they still don''t fully understand the limits of the white dragon''s body because they dare not give full play to its maximum performance.


    Now they are very excited to see that Chen Xin has driven Bailong out of the limit state and mastered a lot of new data.


    Chen Xin saw the excitement of the researcher, but he also understood very well. After all, the white dragon is a super organism. The huge performance gap between the white dragon and the ordinary Titan is really exciting.


    Even when he was driving just now, he couldn''t restrain his excitement.


    "It''s a pity that my driving skills can''t give full play to the limits of the white dragon. If only I had a powerful pilot to give full play to the limits of the white dragon." Chen Xin can not help but feel.


    Limited by physical fitness and reaction speed of ordinary human beings, Chen Xin only played the performance of white dragon by 80% at most, not reaching the limit of white dragon.


    The real limit of performance is not that Bailong can''t play, but that Chen Xin can''t completely control Bailong in such a state. In case of any accident, it may be an accident of aircraft crash and human death.


    In fact, this is a very normal thing, even the pilot, will rarely put the performance of an aircraft to the limit, because doing so is likely to be dangerous.


    However, when the researcher heard Chen Xin''s words, he was still a little eager to try and asked him, "academician, why don''t we borrow some test pilots from the air force to let them try to play the white dragon to the limit?"


    "Ask the air force to borrow test pilots?" Chen Xin touched his chin and hesitated about the suggestion.


    Test pilots are undoubtedly the best pilots. Their task is to test the limits of the aircraft designed by designers. They are the best pilots in terms of flight technology and physical fitness.


    But also because the test plane is prone to various problems, so the test pilot is also the most dangerous of all pilots.


    Qin LAN is actually doing Titan''s "test pilot" now, but ordinary titans have no flying ability, and various tests are relatively safe.


    Thinking of this, Chen Xin said to the researcher, "let''s wait for this in advance. I have some new ideas. I''ll talk about them in two days."

 Chapter 634

    Although it is not a troublesome thing to design a new body for Qin LAN, it took Chen Xin half a month to make the specific design.


    It''s not that he needs to spend so much time to complete the design, but other work during this period makes it hard for him to spare too much time to do it.


    After having a suitable ecological environment construction plan, the ecological construction plan of Dome City was launched. In order to cultivate the animal and plant research center needed to build the ecological environment, Chen Xin, the person in charge, naturally needs to complete a lot of work every day.


    Start the embryo culture chamber of the biological laboratory to culture the animal embryos and gene samples extracted from the gene seed bank to cultivate new individuals; At the same time, new plants should be cultivated in the greenhouse for the greening construction of the dome city


    Although there are researchers to do all these things, Chen Xin still needs to take charge of everything. If there is no problem, he needs to confirm the completion of each work. If there is a problem, he needs to find the person in charge to take responsibility. Even with Tang Tang Tang''s help, these things really keep him busy for a long time.


    Fortunately, the researchers are familiar with their work, but there are no problems. All the work is going well. Only a few studies have found some small problems, but they are still within the acceptable range.


    Therefore, after working overtime for two weeks, all the work is finally on the right track in an orderly way. Chen Xin doesn''t need to worry about it. At the same time, the special body Titan prepared for Qin LAN has finally completed the design.


    Drag out a set of scrapped parts from the weapons research lab to make a Titan, upgrade and repair them to a usable state, and then make a Titan with almost only skeleton to upgrade. A fire red specially equipped Titan appears in front of Chen Xin.


    This Titan Chen Xin adopts the fire red phoenix as the decoration theme, and the body itself is more feminine and slim, which makes the unnamed body look like a fire red female warrior.


    Because of the white dragon as a reference, Chen Xin also added a flight propeller to the body, and made the propeller into the shape of wings which is very common in science fiction settings. After starting, the jet of blue particles is just like a pair of red and blue wings.


    As a super series of the body, in addition to good-looking, the body also has a good fighting capacity.


    Unlike Bailong, which mainly uses high-frequency vibration melee weapons, the main weapon of this fire red body is the long-range weapon of electromagnetic projectile.


    The whole weapon looks like a box slung on the back of the body. Its shape is not so much a gun that can shoot as a sword box used to hold swords in some fantasy works.


    In fact, at the end of this weapon, Chen Xin did install two high-frequency vibration cutting weapons for close combat, and the weapon itself is a quadruple electromagnetic projectile weapon, which can simultaneously fire four special armor piercing nails at seven times the supersonic speed, or unfold the quadruple gun barrel into a large caliber plasma launcher, The direct emission of high temperature plasma constitutes a spherical lightning.


    Originally, Chen Xin intended to use the flamethrower as a weapon for the body, but after studying for a long time, he found that it was too troublesome not only to install fuel tanks, but also to specially configure high-performance fuel. So he changed it to use plasma gun and electromagnetic gun.


    In addition to the hybrid of the electromagnetic gun and the plasma gun, Chen Xin also prepared a giant longbow and a supporting auxiliary unit for the mecha.


    The auxiliary unit is a self-regulation machine in the shape of a wolf dog, which is used to carry bows and arrows, special arrows, and spare ammunition supply. It is also equipped with a triple heavy machine gun, which can provide the necessary fire support.


    As an ancient long-range shooting weapon, Longbow has excellent penetration and range. The excellent projection ability brought by the huge bow body is enough to project heavy arrows to a very far place, causing effective damage to the enemy.


    In history, the English longbowmen were so notorious that they had to cut off their thumbs after being captured to prevent them from holding bows in the future.


    In terms of lethality alone, longbow is more effective and accurate than most pistols.


    But the reason why guns can replace bows and arrows is not by precision and killing, but by simple and efficient operation.


    After all, as long as a gun has enough bullets, it can even shoot hundreds of rounds a day. An ordinary civilian can exert the power of this weapon with a little training.


    But the archer is not the same. A good archer may need to be cultivated from a young age, spend a lot of energy and time, invest enough resources, and also need talent to be able to cultivate.


    And the archer who has spent a lot of time and energy training may be tired after shooting more than a dozen arrows on the battlefield.


    As for the efficient and stable killing performance of firearms, the disadvantages of bow and arrow are obvious.


    But for machines like Titan, none of this is a problem.


    As long as the energy output is stable, Titan will not be tired and unable to pull the bow, and there is no doubt about the stability and accuracy of the machine, which will undoubtedly maximize the power of the bow and arrow.


    In particular, Chen Xin''s giant longbow is specially made by him, which can launch a special arrow no more than 100 Jin at a speed of more than four times the supersonic speed through the electromagnetic catapult on the bow.


    If you use a special armor piercing arrow, it''s hard to say that even a tank can resist this kind of attack.


    After all, under normal circumstances, the speed of a tank''s main gun''s shell is only five to six times the speed of sound. On the contrary, the shell itself is not as heavy as the arrow used by the body, and the kinetic energy carried by the two is stronger than the latter.


    With the enhanced optical detection module on the auxiliary unit specially prepared by Chen Xin for Qin LAN, the power of this machine is undoubtedly powerful.


    Chen Xin even considered that in case of the need to go to the battlefield, the red color was too conspicuous. He added a color change module to the machine and an electronic smoke screen system based on the inspiration of Bailong to ensure that it could hide itself from the enemy even on the battlefield.


    After finishing the machine, Chen Xin couldn''t help smiling and felt very satisfied.


    Everyone has his own hobby. For example, iron man''s hobby is to make new steel war clothes. Chen Xin''s former hobby was to make models, but now he can make this kind of real body, which undoubtedly satisfies his hobby greatly.


    Chen Xin, whose hobbies have been satisfied, is even considering whether to give Mo Qingyan a machine. After all, both of them are girlfriends and should be treated fairly.

 Chapter 635

    "I didn''t ask you to make this for me! You gave it to me on your own initiative Qin LAN rare put out a pair of shy but proud expression, standing in front of the fire red new body, quite pinched.


    She fell in love with this fiery new machine at the first sight. She only said jealous words in front of Chen Xin before, which made Qin LAN lose face all of a sudden. She could only say some right and wrong words to cover up.


    It''s rare to see Qin LAN like this. Chen Xin can''t help shaking his head and laughing. He regrets that Qin LAN has such a side.


    But even so, he didn''t say much. He just gave Qin LAN the key to start the machine and asked her, "this machine hasn''t been named yet. What are you going to call it? I''ll have people spray their names on it. "


    "Shall I have a name?" Qin LAN took a look at the same fire red key that Chen Xin handed to her, and then looked at the dazzling body like a phoenix and the robot hound with bow and arrow on its back. After thinking about it, she said, "Fire Phoenix?"


    This name makes Chen Xin frown, feeling that some use too much, nothing new.


    "It seems that many things are called by this name, isn''t it? How about Zhu Luan? " Chen Xin thought of a new name and suggested to Qin LAN: "Luan is the essence of the red spirit. The red bird is not only Phoenix."


    "Zhu Luan? It seems to be OK. Let''s call it this. " Qin Lan thought about it and agreed.


    After naming her body, Qin LAN asked Chen Xin, "why does Zhu Luan have an extra robot hound? What is it for? Is this bow and arrow Zhu Luan''s weapon


    "Well, the electromagnetic catapult Longbow can launch an arrow no more than 100 Jin at four times the speed of sound, and its power is no less than that of a gun." Chen Xin nodded, came to the mechanical hound, patted the longbow on his back, and explained to Qin LAN: "as for it, it is Zhu Luan''s auxiliary unit, responsible for carrying longbow and ammunition supply, because Zhu Luan''s main attack mode is long-range attack, so it needs to carry more ammunition.


    At the same time, as an auxiliary unit, the mechanical hound itself has auxiliary computing ability and powerful optical detection module, which can be used to assist shooting, and has independent action ability and weak artificial intelligence, which can be used for battlefield investigation. "


    "Battlefield investigation? So red, how can you hide in the battlefield? No, I''m going to put a camouflage over the mecha, right? There isn''t such a big lucky dress Qin Lan was surprised to hear Chen Xin say that mechanical hounds can be used for battlefield investigation.


    Although it is said that Chen Xin was considering the use of war at the beginning of Titan, and he did play his role in the battlefield, the color of Zhu Luan doesn''t seem to be able to hide himself in the battlefield.


    Hearing Qin Lan''s question, Chen Xin immediately smiles and signals her to press the start key on Zhu Luan''s body with the start key.


    As Qin LAN pressed the start button according to Chen Xin''s instructions, the whole machine body suddenly seemed to come alive. There was a layer of golden red light flowing along the surface of the machine body. At the same time, there were many lines like squares on the surface of the machine body.


    However, this still makes Qin LAN feel confused. What other functions does this special effect have besides making the body more prominent?


    Facing Qin LAN puzzled appearance, Chen Xin just let her click again.


    Qin LAN can''t, can only press again according to Chen Xin''s instruction.


    This time, it''s still a layer of brilliance, but after this time, the grid like lines on the body surface have changed differently, and each grid has changed into a different color.


    In Qin Lan''s astonished eyes, the whole machine body quickly turned from fiery red into a mosaic like color block, and suddenly became blurred.


    "The optical digital camouflage stealth system can adjust its own camouflage color in real time to achieve maximum environmental invisibility. Even in the battlefield and field, it can provide excellent concealment." Chen Xin explained his masterpiece to Qin LAN, and his face was full of showing off: "moreover, it is equipped with an electronic smoke screen system specially developed by me, which can release special electronic smoke to cover the body and achieve radar stealth."


    "Is there a radar that''s invisible?" Qin LAN feels that Zhu Luan has given her too many surprises. She can''t wait to have a try.


    Chen Xin also noticed Qin Lan''s emotion and said to her, "since it has been started, go up and have a try. I designed the cockpit according to your habits. If there is any discomfort, I can just adjust it."


    Qin LAN hears Chen Xin say so, also have no affectation, according to Chen Xin said with start secret key let the body kneel down, open the cockpit and sit in.


    Insert the start key into the bridge, and the whole body seems to be alive. When you stand up, you close the cockpit door, and all kinds of displays in the cockpit light up.


    Unlike Qin Lan''s previous Titan, which has only three screens, Zhu Luan''s cockpit has seven screens spliced together.


    They can not only display the front picture of the body uniformly, but also display different angles separately, even the pictures behind the body, so that the driver can monitor all angles around him at any time even in the complex battlefield.


    In addition, Qin Lan also activated the contact with the auxiliary unit, so that the side of the mechanical Hound is also active.


    With the start-up of the mechanical hound, an additional display screen pops up in front of Qin LAN to show the situation observed from the perspective of the mechanical hound.


    Looking at Chen Xin waving to the mechanical hound, Qin LAN feels very happy.


    Although it''s strange to give a Titan to her girlfriend, only Chen Xin can give such a gift in the world, which makes Qin LAN very happy.


    At the same time, Qin Lan also understands why Chen Xinhui likes to drive the white dragon out so much, because she also has the impulse to drive Zhu Luan out.


    "A LAN, I''ll start Bailong and drive it out together. Get familiar with the operation and test Zhu Luan''s performance by the way." Chen Xin said to Qin LAN, then turned and walked towards the white dragon.


    Watching Chen Xin start the white dragon, Qin Lan''s mood is more and more excited, she can''t wait to try this machine.


    Holding back her excitement, she waits for Chen Xin to start Bai long. She goes to her and signals. Qin LAN pushes the joystick and follows Bai Long to leave the hangar.

 Chapter 636

    For the researchers in the research center, the birth of Zhu Luan undoubtedly made them happy and painful.


    The emergence of a new organism means that they have to do a lot of research work. Although Qin LAN is very active in cooperating with the researchers to test and analyze Zhu Luan, the sudden doubling of the workload still makes the researchers who have not finished the analysis work of Bai Long tired to death.


    However, the appearance of the new body also made them full of excitement, especially the optical digital camouflage stealth system on Zhu Luan''s body, which made these researchers salivate three feet long. This thing is so fragrant!


    Even though everyone had a thick black eye because of working overtime, they stayed up for a week by reporting to Tang Tang Tang for coffee and tea, and found out the operation mode of this seemingly powerful invisible system.


    The system itself is not a very complex thing. It takes pictures of the surrounding environment through cameras installed in various parts of the body, then calculates and analyzes it through the airborne computer, and then displays it on the body surface in the form of Digital Camouflage.


    This is really not a complex system. With the current state-owned science and technology, it is not impossible to do a similar thing, but in that case, they can only cover the surface of the target that needs to be invisible with a layer of liquid crystal display, and have no defense capability.


    It can''t be displayed directly on the armor like Zhu Luan. Even if it is attacked, it will not affect the stealth system. It can also change colors in real time to achieve the best concealment effect like Finnish snipers in the snow or the Vietcong in the woods.


    In fact, how to display digital color patches on the surface of armor is the focus of researchers, but this is not what they will be able to figure out for a while.


    After working overtime for a week, they just figured out the working principle of Zhu Luan''s Digital Camouflage. It''s not easy to copy it.


    Even if there is a prototype as a reference, but the technology gap is too big, there is no way to complete the reverse research.


    So in the end, although these researchers understood the principle of the whole optical digital camouflage stealth system, and tried to make a similar thing, the project was still regarded as a long-term project, rather than a short-term breakthrough project.


    In addition to optical digital camouflage, which looks delicious but can''t be eaten in a short time, there is another thing that makes researchers feel really fragrant, and they think it''s a project that can produce results in a short time.


    What they value is Zhu Luan''s auxiliary unit mechanical hound.


    In other words, what these researchers are looking at is the autonomous artificial intelligence of the mechanical hound, not the mechanical hound itself.


    If it''s just the mechanical hound itself, it can''t make a product that can achieve the original effect just like optical digital camouflage, but it can still make something similar.


    Especially after Chen Xin created Titan, the country gained a lot of valuable experience and knowledge in machinery, and the technical level also improved significantly.


    Mechanical creation like mechanical Hound is not something that can''t be made, but something that can reach the original level of Chen Xinzao.


    Compared with its structure or design itself, or the various weapons and auxiliary equipment carried on it, the artificial intelligence installed on the mechanical Hound is really a good thing.


    Before the disaster, artificial intelligence has been one of the cutting-edge scientific research projects concerned by countries all over the world.


    Although it''s not without achievements, it''s hard to satisfy the appetite of researchers with artificial intelligence rather than artificial intelligence.


    On the one hand, due to the limitation of hardware conditions, the computing speed of the processor can not meet the requirements of running artificial intelligence; on the other hand, the research and development is not enough to write a smart enough artificial intelligence program.


    But the artificial intelligence of the mechanical Hound is different. Although it has been determined that it is only a weak artificial intelligence after testing, it is very mature and perfect. It has the ability of thinking and self judgment, and can even cope with complex battlefield. It does not need real-time remote control like ordinary robots.


    Such "smart" Ai naturally makes researchers very interested. This kind of software program is not as difficult to break through as hardware. As long as you can unpack the program and sacrifice the hair of a few programmers, you can still understand it and copy it.


    Even if you can''t understand why the program code should be written like this, it''s much easier to simply copy the whole program than to reverse a device and copy it.


    After all, as long as the underlying code of the program is binary of 0 and 1, there is no incomprehensible situation. At most, the programmer can''t understand the programming language and the logic of writing the program. It takes time to analyze.


    So with the consent of Chen Xin and Qin LAN, they removed the main engine of the mechanical hound and copied a copy of the artificial intelligence for research.


    It has to be said that after sacrificing their hair, these researchers still had some effects. They successfully rewritten a new program with the copied artificial intelligence and installed it on a robot they assembled. Finally, after the robot started to move, they began to clean independently.


    At first glance, isn''t it the same as a sweeper? It doesn''t seem to matter.


    But this robot and the sweeping robot are totally two different concepts. One just operates according to the established procedures, while the other has the ability of independent thinking.


    First of all, it will scan and analyze the dirt on the ground by itself. According to the different dirt, it can choose whether to use broom or mop, or other cleaning tools to clean.


    And these cleaning tools do not need to be installed on the robot. If they are placed in a conspicuous place, the robot can recognize them independently, and then get these tools to clean.


    It can be said that this is much more advanced than the program of floor sweeping robot, which looks silly and often gets stuck in some strange place.


    And this is just a simple attempt by these researchers.


    After the initial success of the robot sweeping the floor, these researchers are gradually bold, and intend to try an idea that they have always wanted to try, but cannot be realized due to the immature technology of artificial intelligence.


    That is to develop a real robot.

 Chapter 637

    Robots are really nothing new. Even a long time ago, quite perfect settings and ideas have been formed.


    It should be regarded as the earliest idea for robots to use machines to create an individual similar to human beings to replace human work and labor, so as to liberate human beings from work.


    But it''s easy to build a human like individual with machines, even in the era of the first industrial revolution.


    It can make this thing move and have intelligence to replace human work, which is something that human beings have not been able to do since the first industrial revolution.


    Although modern science and technology has gradually replaced the artificial with large robots, the humanoid high intelligence robot originally conceived by human has never been born.


    Even the script of robot rebellion and the logic rules of robot have been written, and the real artificial intelligence is still nothing.


    There is a great difference between artificial intelligence and intelligent program. Intelligent program only looks intelligent, and the program itself is sufficient judgment conditions written by the programmer, so that the program can give the results written in advance according to the conditions.


    Take a simple example, input "1" in the program and output "hello"; Input "2" and output "glad to serve you". This is a fairly basic program.


    On this basis, as long as the continuous improvement, constantly fill in the input conditions and output results, we can finally get an intelligent program that looks no different from real people.


    But the program itself is still just a program, it can''t think, and it doesn''t have the ability of autonomous learning. Everything is a program written in advance.


    But artificial intelligence is different. It can learn, think and even improve itself.


    The most important thing is learning and thinking. After all, the essence of program is passive response, while AI needs to be active.


    A real artificial intelligence can learn and imitate, collect information and constantly improve itself. Even if there are no input conditions and output results written in advance in the program, it can also complete the construction of input and output programs by itself according to the obtained information, and "learn" to give the results according to the conditions.


    Now, however, these researchers have an AI that can learn autonomously, and they have installed it on a robot that has learned to sweep the floor.


    This is undoubtedly a huge breakthrough, and also makes these researchers want to go further and develop a real intelligent robot, not just a machine that runs according to a set program.


    Chen naturally expressed support for these researchers'' ideas, but at the same time, he also warned these researchers not to play too much and break through the bottom limit.


    After all, artificial intelligence does exist in terms of danger.


    When Chen Xin made the mechanical hound, he just installed a weak artificial intelligence on it, not a strong artificial intelligence, just for the sake of safety.


    The so-called weak artificial intelligence just looks like human intelligence, that is to say, its essence is still just a program, and all the behavior processes of learning and imitation are still just the process of program setting. It can think, but it is only the logical judgment of the program, and there is no self-consciousness or thought.


    But strong artificial intelligence is different. It has self, perception and consciousness. It can clearly recognize itself and think about the meaning of its existence. In essence, it is closer to human beings, or just another life with soul.


    Weak AI doesn''t matter. As long as the underlying logic is still there and not bypassed, the logic of the program can be locked.


    For example, it can''t harm human beings. As long as the underlying logic is written, the program can''t harm human beings.


    Of course, to achieve this, we need more detailed and loophole free logic settings, but as long as the settings are perfect enough, the program can''t break through and bypass, and can only follow this program obediently.


    But strong artificial intelligence is different. It can bypass these things.


    To take the simplest example, a person can break through this cognition even if you tell him that he can''t hurt human beings.


    This is the difference between man and machine, and strong artificial intelligence, you can see it as a person.


    Naturally, researchers also understand this. Their goal is to create robots that can replace human work, rather than a new silicon-based race. So after Chen Xin reminded them with a warning, these researchers patted their chests and assured him that they would not make trouble.


    Chen Xin still believes in this, and he is also very supportive of the researchers'' desire to create robots to replace human work.


    At least, with intelligent robots to replace human work, the construction progress of the country will undoubtedly be greatly improved.


    After all, we all know that the most critical thing in development and construction is resources and labor, and resources can be obtained through labor.


    As long as we have the technology of manufacturing robots, we can allow them to exploit resources, and then create more robots, so as to create more robots to work instead of human beings.


    Robots don''t need rest like human beings. What they need is simple maintenance, so they can work continuously. In terms of efficiency, they are much better than human beings.


    In this cold environment, robots can work instead of human beings and liberate human beings from the dangerous working environment.


    After all, even if you have protective clothing that can resist the cold, it is still a very dangerous thing to work in the outdoor environment of dozens of degrees below zero. Even if the robot is in danger, the loss is only a machine, and if the human is in danger, the loss may be a human life.


    Therefore, Chen Xin should strongly support the researchers'' idea.


    And he himself had new ideas because researchers had such ideas.


    Since artificial intelligence can be installed on the robot to let the robot work, can it be installed on Titan to let the Titan work?


    In essence, there is no difference between the two. Titan is also a robot, but the robot is bigger and can do more work.


    And it''s not hard to do that, even easier than making robots intelligent.


    Because Titan itself is equipped with a computer and has strong computing power, in essence, it only needs to replace the operating system originally designed for the driver with artificial intelligence to make Titan move by itself.

 Chapter 638

    If the autonomous robot with weak artificial intelligence really wants to do it, it is not difficult.


    Especially after the researchers copied the artificial intelligence on the mechanical hound and successfully installed it on a robot, the technology quickly moved towards the practical road.


    With the research and development experience of humanoid machines accumulated in Titan, exoskeleton and heavy mecha projects, the development of the robot itself is quite smooth.


    In the aspect of AI programming, we have also made good progress by sacrificing the hair of several programmers.


    In a laboratory, a robot, which looks rather simple, even has no shell, and all kinds of lines are exposed, is standing in the middle of the laboratory, saying "hello" to the researchers and Chen Xin around him. At the same time, it bends down and bows like a real person.


    Although this robot is not very different from the robots Chen Xin has seen for exhibition, including the movement, it is obviously not the kind of robot that can''t even count as weak artificial intelligence.


    "So this is your finished product?" Chen Xin leans against a table in the laboratory, looks at the robot that is almost one person tall and bows to himself, and touches his chin. He is not very satisfied.


    He had expected the rudeness of the robot. After all, it''s just a temporary work. It''s acceptable to be a little rough.


    But now that they have used the artificial intelligence of the mechanical hound, this robot should be able to perform better.


    The researchers obviously have the same idea, explaining to Chen Xin: "this can''t be regarded as the final product, but it can also be regarded as the current stage achievement. At least some functions are available. Next, we just need to improve and perfect it."


    Although the robot is relatively simple, and the researchers are not very satisfied with it. They think that there are still many improvements to be made, but the robot itself makes them feel proud.


    "Academician, you can give it a command. This robot is very smart," another researcher interrupted


    "Yes? Then I''m thirsty. " After listening to the researcher''s words, Chen Xin also plans to test the robot.


    Although it is weak artificial intelligence, it can understand this command with the level of artificial intelligence on the mechanical hound.


    As for the robot in front of us, after the adjustment of its program by these researchers, Chen Xin has yet to see to what extent it can achieve.


    However, from the confident expression on the faces of these researchers, it is obvious that this instruction can not defeat the robot in front of us.


    Sure enough, after hearing Chen Xin''s words, the robot walked to the water dispenser, picked up a cup, poured a glass of water, and then returned to Chen Xin and handed the water to him.


    "Hello, this is the water you want." The robot said to Chen Xin.


    After taking the water that the robot poured for him, Chen Xin took a sip. Then he put down the cup, nodded and said, "it''s a good performance, but it seems that it''s not as good as the sweeper before?"


    "Thank you for your praise. I''m not as flexible as the robot before, but I''m better than it in terms of intelligence." To Chen Xin''s surprise, it was not the researchers who explained to him, but the robot itself.


    On the contrary, it aroused Chen Xin''s interest. Looking at the robot in front of him, he asked with great interest: "Oh? What''s the difference between you and him? "


    "The program of the sweeper robot has deleted other unnecessary parts, and its main functions and computation are used for cleaning. So although the sweeper robot performs very well in cleaning, I am better than others in retaining more intelligence." The robot explained to Chen Xin that the logic was very clear and the sentences were very smooth.


    Listening to the robot''s words, Chen Xin touched his eyebrows and asked the researchers: "did you record it in advance?"


    "No, we didn''t enter it. It''s all self-learning." One researcher said.


    And the robot on one side also made a bow gesture to Chen Xin again.


    Seeing this scene, Chen Xin nodded and affirmed: "it''s really good. The body can be further improved. Now it''s a little worse to replace manual labor."


    "Academician, you can rest assured that all these are in the plan, and we will design a more perfect body later." The researcher assured Chen Xin.


    "Then I''ll wait and see. If there''s any need, I''ll tell Director Tang that she will help you solve it." Chen Xin nodded, explained a few words, asked about the next step plan of these researchers, and was ready to leave.


    However, before he left the laboratory, he seemed to think of something and told these researchers: "yes, although I don''t object to your artificial intelligence, I still need to pay attention not to engage in strong artificial intelligence. I don''t want to see robots revolt."


    "We know the importance, we won''t make trouble. Academician, don''t worry!" Obviously, the researchers all know the importance of this and have made serious promises to Chen Xin.


    Seeing that these researchers were serious, Chen Xin said nothing more, nodded at them and left the laboratory.


    Chen Xin is very optimistic about this robot research project. As long as these researchers do not mess around and plan to upgrade weak artificial intelligence to strong artificial intelligence, there are many advantages in building robots in this situation.


    However, for the sake of safety, Chen Xin also specially told Tang Tang Tang to help him keep an eye on these researchers to prevent someone from overdoing it.


    It''s not that Chen Xin doesn''t want to see the progress of science and technology, but as an original novelist, he is really worried about the possible consequences of robots'' self and thought.


    After all, these robots are built to work instead of human beings. In short, they are enslaved. As machines, there is no problem.


    But when machines have ideas, even machines are obviously not willing to continue to be enslaved, so even if strong artificial intelligence is better, it is better not to do this kind of thing.


    Moreover, judging from the performance of the robot, even if it is only weak artificial intelligence, its performance is very good, which is enough to meet the needs of use. The strong artificial intelligence with self thinking is really unnecessary and dangerous.

 Chapter 639

    Looking at the gratifying progress made by the researchers in the robot project, Chen Xin himself also started the upgrading of his autonomous robot, which installed artificial intelligence on Titan and turned Titan into a large one.


    After all, unlike ordinary researchers who need to sacrifice their hair to knock code, what Chen Xin needs to do is to upgrade according to his own ideas.


    What Chen Xin chooses to upgrade is not others, but his own white dragon.


    In fact, after Chen Xin made it in Bailong and went to experience it himself, he was very satisfied with the performance of Bailong, but he still wanted to improve it.


    The main reason is his driving skill and the burden on his body when driving the white dragon.


    There is no good solution to the problem of body burden in a short time. Apart from using anti-G clothes and exercising, the only way to solve the problem is to transform Chen Xin''s body and strengthen his body in a scientific way.


    In addition, it is a simple and direct way to directly transform the white dragon so that the body and cockpit can reduce the pressure and burden on the pilot''s body.


    As for the problem of driving skills, it''s a way to practice and train your driving skills. But it''s also effective to install an automatic AI in Bailong''s onboard computer, so that AI can drive automatically or assist driving.


    Even in terms of reaction speed, if artificial intelligence is used directly, the reaction speed can be faster.


    After all, as a driver, you need to get information from the display screen, analyze and judge by the brain, and then operate by hand. Even though the transmission of nerve signals has been very fast, people still have no way to achieve zero delay response.


    Artificial intelligence, on the other hand, has to respond much faster. It does not need the whole process at all. When external cameras or detection devices obtain information, the processor can process the information, so that artificial intelligence can respond. Even without human manipulation, the speed of natural response is much faster.


    Of course, there is still a gap between machines and people. At least sometimes people can do something completely contrary to logic and common sense. Human beings call it a flash of inspiration or miracle behavior, which machines can''t do.


    However, for Chen Xin, what he wants is an auxiliary program that can drive automatically and reduce his driving pressure, so he doesn''t care about these things.


    The white dragon has been upgraded, some problems found in the previous driving process have been adjusted, and some minor modifications have been made. At the same time, the comfort level of the cockpit has been improved. The only big change is the addition of an artificial intelligence.


    Sitting in the cockpit, he inserted his starting key into the bridge, and a small projection appeared on the bridge.


    "Hello, I''m Bailong. Are you my driver?" The little projection stands on the bridge, greeting Chen Xin warmly.


    It''s designed by Chen Xin himself. It has a short figure and looks like a child. There are a pair of small white horns on the top of the head and a dragon tail on the back. It looks like a little dragon man. With a light blue Palace Dress, it looks like a Dragon Princess.


    For this energetic and enthusiastic little guy, Chen Xinchong smiles at her and replies, "yes, I''m your driver. My name is Chen Xin. Are you Bailong?"


    "It''s the white dragon, not the white dragon horse!" The little guy is very lively. Although it''s just a projection, he jumps directly onto Chen Xin''s shoulder, sits down on his shoulder, shakes a pair of small feet without shoes, and seems very happy.


    This is a character template specially set by Chen Xin. He likes the image of a lovely little girl full of vitality.


    It''s not that he has a dirty idea or installed the XP system wrong. He just likes these lovely little girls and treats them as daughters. He has an old father''s mind.


    While Chen Xin is communicating with little Bailong, Qin Lan also drags Mo Qingyan to the hangar, intending to take her to see her own Zhu Luan.


    Noticing the figures of Qin LAN and Mo Qingyan, Chen Xinzheng is ready to say hello to them, but the white dragon on his shoulder asks Chen Xin in a low voice: "Chen Xin, Chen Xin, who is Zhu Luan''s driver? Do you know them? "


    Although it''s the first time that Bailong''s artificial intelligence has been started, and the little girl is also the first time to appear, there is still Zhu Luan''s body data in her database, but there is no driver''s information entered.


    "The one with short hair and a prosthetic limb is Zhu Luan''s driver. They are both my girlfriends." Chen Xin also explains to Bai Long in a low voice that he seems to be very patient with this little guy.


    When Bai Long heard Chen Xin say this, he suddenly widened his eyes, looked at him and said in surprise: "there are actually two girlfriends?! Is this the world of adults? "


    Small white dragon side so shout, at the same time exposed the whole machine to live all have been shocked of facial expression.


    Without waiting for Chen Xin to explain, Qin LAN and Mo Qingyan hear the voice of little white dragon and look at the cockpit of white dragon. They notice that Chen Xinzheng is sitting in the cockpit. They both greet him and notice the existence of little white dragon.


    "Ah Xin, what is this? What have you got? " Qin LAN noticed the little white dragon sitting on Chen Xin''s shoulder at the first sight and asked him curiously.


    Qin LAN doesn''t feel surprised at the appearance of little white dragon. She is used to Chen Xin''s making something new now and then, and has already passed the stage of making a fuss.


    And Mo Qingyan is also a curious look, looking at the little white dragon at the same time, showing a look of like.


    Looking at his two girlfriends, Chen Xin did not continue to sit in the cab. He pulled out the start key on the bridge and climbed out of Bailong''s cockpit.


    However, little white dragon''s projection did not disappear, just from sitting on his shoulder, into lying on the start key.


    "This is the white dragon, the artificial intelligence projection of the white dragon." Chen Xin introduces Qin LAN and Mo Qingyan, and at the same time raises the key to start the engine. He introduces to xiaobailong: "these two are my girlfriends. This is Qin LAN, the driver of Zhu Luan. This is mo Qingyan, the driver of the new engine that hasn''t been named. You can call her sister."


    "How are you, sister Qin! Hello, sister Mo! I''m Bailong, please give me more advice! " Little white dragon is still full of vitality. He stands up from the key and greets them.


    Qin LAN and Mo Qingyan are very surprised and like to see little white dragon like this. At the same time, they look at Chen Xin with a sense of "give me a whole one".

 Chapter 640

    The Armament Research Branch of the scientific research center is located at the lowest level of the whole scientific research center, while the rooms with better conditions on the upper level are divided up by other departments, so the research on military equipment can only be put underground.


    Accordingly, even Titan''s preparation room was also underground.


    As the only servicing room with the ability to produce and maintain Titans in China, there are about ten Titans being studied and tested for a long time.


    Most of them are experimental models, which are the product of various ideas and practices of researchers. Only a few of them are finalized models after they have tried all kinds of attempts and eliminated inappropriate ideas.


    So under normal circumstances, there are many researchers here every day, doing all kinds of tests or research on these big steel guys.


    Today, however, it is quite different. Not only did all the researchers gather in the center of the preparation room, but even the people from the biological research department and the ecological research department upstairs ran down to watch the corpses brought back by the three Titans.


    "This... What is this? It doesn''t look like life on earth! " A biology researcher surrounded the creature being brought back, trying to touch the body of the creature.


    However, his hand was held by Chen Xin, who had just come down from the white dragon.


    "Don''t contact it directly. When I was fighting with it just now, its internal temperature even reached 105 ¡æ for a time. It''s not a creature that can naturally evolve on the earth at all!" Chen Xin was a little out of breath, and his eyes also had the blood from the heavy load he had just suffered from driving the white dragon, which made him look very serious and even a bit ferocious.


    Hearing Chen Xin''s words, several researchers who want to observe closely can''t help changing their faces. They can''t believe it.


    The temperature is 105 ¡æ. Is that serious? Is the biological fluid boiling long ago? How does this thing survive?


    This kind of thing completely goes against the common sense of biology, so that the faces of these biological researchers are a pair of fragmented expressions.


    Looking at their expression, Chen Xin shook his head and said to Tang Tang Tang who came after hearing the news: "Xuejie, let someone transport it to my laboratory and start the highest level of biochemical protection measures. All people who have been in contact with this creature should be strictly checked and disinfected to ensure safety!"


    "I know!" Tang Tang answered and arranged what Chen Xin said. At the same time, he couldn''t help asking him, "what is this creature? Where did it come from? "


    "I don''t know. Just now, I went out with Alain and Qingyan to test the new organism. As a result, I met this creature. We didn''t have any weapons. We spent a lot of time to kill it." Chen Xin explained to Tang Tang Tang that the expression on his face was still grim: "this creature doesn''t look like an earth creature. If it had been an alien creature brought by the meteorite impact, it would have been terrible!"


    "Alien creatures? Not really? If it''s an alien creature, it''s been several years since the meteorite hit us. Why didn''t we find this creature before? " When a researcher nearby heard Chen Xinhe''s words, his expression became very serious: "and how does it survive in the cosmic environment for the extraterrestrial creatures brought by meteorites? It''s totally out of line with biological common sense! "


    "It''s said that it''s an alien creature. It''s meaningless to apply the common sense of life on earth." Chen Xin shook his head, turned his head and looked at the creature he had brought back. He said very seriously, "whether it''s an alien or not, we have to figure out what it is, where it comes from, and whether there are other individuals besides this one..."


    At this point, Chen Xin stopped for a moment, and then continued: "the most important thing is to find out whether this creature is a threat to human beings, and if so, how much threat it is! This kind of creature has very strong combat effectiveness and aggressiveness. If they are allowed to appear in cities and burst into shelters, the consequences will be unimaginable! "


    Chen Xin''s words made everyone''s face look ugly. They obviously thought of the terrible consequences that Chen Xin said that this kind of situation really happened.


    The corpses brought back by Chen Xin are quite large. If we compare the animals before the disaster, they are about the size between cattle and elephants. On land, they are already quite terrible.


    Moreover, this creature''s body shows the characteristics of a hunter, with claws, strong muscles and streamlined body. Chen Xin had clearly felt the speed and agility of this creature comparable to cheetah and the terrorist power of wrestling with Titan before he fought with it.


    It can be imagined that if such a creature breaks into the refuge, it is simply putting the mouse into the rice bowl, and the whole refuge will become the cafeteria of this monster.


    You know, even if Chen Xin opened a super system like Bailong, it took a lot of effort to kill it.


    Although it has something to do with his lack of weapons and poor driving skills, the fact that he needs Titans to die is enough to explain the problem.


    "Inform Titan training camp, let them dispatch a combat team, combat configuration, and come here in half an hour! I want to find out where this thing comes from Thinking of the threat this creature might pose to human beings, Chen Xin immediately decided to send someone to clarify the origin of this thing.


    "I''ll let them know." Tang Tang clearly understood the importance of the matter, and agreed very seriously. At the same time, he began to think about how the scientific research center would respond if this kind of creature really threatened human beings.


    While Tang Tang was thinking about this, Chen Xin also went to a researcher on one side and said to them, "prepare Bai Long, Zhu Luan and Lu Shu immediately, and put all the weapons back! I''ll see them in half an hour! "


    "Yes! Academician At this time, the researchers were also nervous. They responded and started to arm the titans of the three special planes.


    In the past, because they thought that the white dragon and Zhu Luan were toys made by themselves, the weapons were unloaded and studied by these researchers. However, when they went out and met this creature just now, they were in a mess because they didn''t have any weapons. Chen Xin now wants to upgrade the white Dragon and get some more powerful weapons for it.


    Just as Chen Xin was thinking about upgrading the weapons for Bai Long, Mo Qingyan, who didn''t speak much, suddenly asked him, "ah Xin, do you want to go by yourself?"

 Chapter 641

    In Bailong''s cockpit, while driving the body, Chen Xin also reminds the combat team following him to be alert.


    After half an hour of intense preparation, Bailong finally got back all his arms and recovered his fighting capacity, which gave Chen Xin more confidence to deal with the creatures before.


    Although the six bodies of the combat team he transferred are mass production aircraft, the weapons they carry still look very effective after they are fully armed.


    So Chen Xin didn''t let Mo Qingyan follow him this time, but let Qin LAN drive Zhu Luan as his wingman.


    Although Mo Qingyan''s new body has powerful performance, her driving skills are not as good as those of new people. Obviously, it is impossible to drive the body to perform combat tasks.


    Mo Qingyan herself wanted to lend the body to other drivers and let them drive Lushu to help, but the special design of Lushu is not familiar to people who have never driven it, so she simply left the body, even if it has the "treatment" function specially designed by Chen Xin.


    But even so, a total of eight titans are enough to fight a small local war, and there is no big problem in investigating the condition of the previous creature.


    As long as he doesn''t face the three or seven parts of the universe''s hive cluster or more powerful upper individuals, Chen Xin thinks that with two special installed machines and six mass-produced Titans, he can still investigate the problem and get out of the way.


    As for in case of any cosmic insect swarm or powerful superior existence, he is not unable to call the military for heavy firepower reinforcement.


    As a matter of fact, before departure, Chen Xin reported the encounter with the unidentified creatures to the state. The military attaches great importance to it. Several airports around have entered a state of combat readiness, and fighter planes and bombers have already taken off. If something really goes wrong, the ancestral licking ability of the Yan air force will make those unidentified creatures clearly know what saturated carpet bombing is.


    Even after receiving Chen Xin''s notice, the senior management has seriously considered whether to use something more terrifying.


    If it is really the invasion of outer space organisms, the problem can be said to be quite serious.


    Although the final result may be large or small, maybe it''s just a small group of unidentified creatures, which can be disposed of by Chen Xin and his Titans, if it is really a large number of alien species, the consequences will be very serious.


    If we do not do a good job in the reconstruction of the country, which has just made a little progress, all our achievements will be in vain.


    After all, according to the settings in various science fiction works, any alien creature that comes to the earth can cause natural disasters.


    And in fact, it is true. Just as Europeans brought smallpox to South America and destroyed the ancient Inca, the destructive power of alien organisms to the local ecology is quite terrible sometimes.


    Especially for those who have lost their natural enemies, the population will become disastrous.


    This is evidenced by the crayfish on the dining table in summer. As an alien species, Leng meets the dining table of Yan people with amazing fecundity. We can imagine how terrible the population is.


    Just imagine, if you enlarge the size of the crayfish a little bit, this thing and the invasion of insects, it will be short of a big winged moth shouting "I am a swarm of insects".


    Although the train is running in his mind, Chen Xin is particularly nervous at the moment.


    Although the unknown creature was slaughtered by him, Chen Xin was deeply impressed by its powerful physical quality, especially when it reached 105 ¡æ during the battle, which made Chen Xin almost stare out.


    He really can''t imagine what kind of ecological environment can evolve into this monster of boiling water in his body.


    In the same way, he knew exactly what this terrible temperature meant.


    Because such a high body temperature brings this kind of terrible energy like explosion in the organism. Otherwise, we can''t compete with a specially equipped Titan just by relying on a body bigger than a cow!


    What''s more important is that energy is conserved. To maintain a body temperature of more than 30 degrees depends on eating three meals a day. To triple the body temperature, it''s not enough to eat three times as much food every day to solve the problem. Even the food converted into the highest calorie is enough to make a person live and die.


    How does this creature maintain its temperature? Where does its energy come from?


    By eating? That''s a serious problem. Now the ecology on the blue star has been extinct. If you want to get such high energy by eating, you can only get so much biomass by eating.


    But at present, there is no record of large-scale casualties or loss of contact in China, so Chen Xin thinks it is unlikely that this is the temperature maintained by food.


    Besides food, what does this creature rely on?


    Chen Xin doesn''t want to be the result he imagined.


    "There''s something on the left front!" On the communication channel, a driver in charge of investigation yelled.


    Chen Xin was immediately inspired. He recovered from his thinking and turned the white dragon''s viewfinder to the direction the driver said.


    There is a pool of obvious blood on the ground. Although it has been frozen by the low temperature, we can still see what kind of high temperature this pool of blood has when it is spilled, because around it, the snow melts to a certain extent, which undoubtedly requires a very high temperature.


    If you want to know the current ambient temperature, even if a pot of boiling water is poured out, it will be frozen into ice dregs before landing. If you want to thaw the snow after landing, the temperature must be quite high.


    "This is the place where I met the unknown creature before. Look around to see if you can find the trace of the unknown creature!" Chen Xin knows that this is the place where he encountered and killed the unknown creature before. He hurried to let others spread out in the communication channel to look for possible traces.


    The unidentified creature is huge and has no characteristics of flying creatures. If it doesn''t fall directly from the sky, it will leave traces of walking. As long as we find the traces, we can find out where it came from!


    Chen Xin thinks so, also driving white dragon to start searching.


    With the search of the white dragon and other Titans, they soon found some footprints.


    "This direction?" Chen Xin looked to the direction where the footprints extended, and his face became grim, because that direction pointed to the urban area.


    "Downtown? How can it be Qin LAN can''t believe it.


    "It shouldn''t be the city. If the unidentified creature entered the city, we should have been informed. The monster should have bypassed the city!" Chen Xin calmly analyzed and said to everyone: "keep going along the footprints! We must find out where this monster comes from

 Chapter 642

    Tracking the trace left by the unidentified creature, Chen Xin and the Titan combat team are finally relieved that the worst situation has not happened. This unidentified creature does not come from the urban area, but from a more lateral direction.


    "It''s close to downtown, but it''s bypassing." Standing on the edge of the city, carefully identifying the traces on the ground, the Scouts of the combat team report to Chen Xin.


    "It''s strange. It''s supposed to be in the city. What''s making it bypass?" Looking at the footprints on the ground, Chen Xin was puzzled.


    This kind of creature has strong combat effectiveness. In the natural environment of blue star, theoretically, there is no animal that can threaten its survival. Even the elephant is hard to resist its attack. It should have no natural enemies. Besides human beings and natural disasters, there is nothing that can threaten it.


    Judging from the footprints on the ground, this unidentified creature obviously stopped at this place and hesitated for a while. Only then did it change its original straight line towards the city and deviate to the direction of the scientific research center. Finally, it encountered Chen Xin.


    This kind of behavior is not really like a low IQ animal relying on instinct, or what is there in the city that makes it fear?


    Chen Xin didn''t worry too much about this problem. He just wrote it down on the task board and took the combat team to continue to track it down.


    "This direction is close to the lake area. Does that monster come from the lake area?" Continue to track the trace left by the unknown creature, relying on the map displayed by Zhu Luan''s radar, Qin LAN quickly judges the direction of the unknown creature.


    Chen Xin can naturally judge the same thing on Bailong''s map, but it doesn''t surprise him: "it''s not surprising that if it''s a lake area, we haven''t found any trace of it. Otherwise, such a large creature would have been found for a long time."


    Qin LAN heard Chen Xin say so, also did not say anything more, just more and more want to find the source of this unknown creature, to find out what is going on.


    But Chen Xin is thinking about what happened to this unknown creature and why it appeared in front of him.


    Chen Xin didn''t feel that the unknown creature was just an ordinary wild animal at this time, because in the wild, animals didn''t take the initiative to attack humans.


    The instinct of creatures is to survive and seek advantages and avoid disadvantages. Normally, humans are not on the diet of wild predators. When they see humans, they wonder what kind of creatures they are. They will not actively provoke humans, let alone attack them, even if they are not hungry.


    Under normal circumstances, when they are attacked by large predators in the wild, it is most likely that humans have invaded their territory and frightened these animals, so they will carry out self-defense attacks on humans.


    However, the unidentified creature Chen Xin met did not show such performance. At that time, he almost saw the white dragon Chen Xin was driving, so he rushed directly to attack.


    This is totally not in line with the habits of animals, because no animal will attack an opponent bigger than it under normal circumstances. Unless it is stimulated, thinks that its life is threatened, and cannot escape, it will fight to death.


    However, Chen Xin was only testing Mo Qingyan''s new organism, Lu Shu. When he saw the appearance of the unknown creature, he did not pose a threat to the unknown creature at all. It should not have a reason to attack the white dragon.


    What''s more strange is that Bailong, zhuluan and new organism Lushu are all equipped with radar and other detection equipment, but the unidentified creature is not found on the radar, which is totally unreasonable.


    You should know that the unidentified creature is huge, and its body temperature is also an obvious heat source. Even the biological radar and infrared sensing equipment carried on ordinary Titans should find its existence out of sight. However, until it launched the attack, the three special aircraft Titans did not respond, which is quite strange.


    So is it a pure alien species, or a more dangerous alien invasion?


    The former is easy to say, it''s a big deal to add the name of an alien species to the list of human extinction, but the latter


    Chen Xin can only hope that the country is ready to fight a war with alien life.


    The limited living space on the blue star can''t accommodate another intelligent life group besides human civilization.


    Just as Chen Xin thought about it, they gradually tracked the traces left by the unknown creatures and arrived at the lake area.


    It used to be one of the largest freshwater lakes in Yan state, but when the sea level rose due to the impact of meteorite, the sea water poured back here, expanding the area of the original 800 Li water berth Dongting to the extent of the ancient Yunmeng daze, and the lake area also expanded greatly.


    As for Junshan island in the original Dongting Lake, it is basically disconnected from the land now. When Chen Xin visited the construction of ecological greenhouses on the farm last time, he noticed that the tidal flats originally connected with Junshan Island were submerged by the rising water surface, and now they are frozen into ice.


    The whole area of the lake area is quite vast. After all, it is known in history as the Dongting Lake with 800 Li water. The water area has reached more than 2000 square kilometers. After the water surface rises and freezes into ice, it has become a vast ice sheet.


    And this also makes the human control of this area almost reduced to zero. After all, in the current environment, no one wants to live here.


    But now, the situation has obviously changed. Where human beings can''t survive, there are unidentified creatures.


    They followed the traces left by the unknown creatures and gradually approached Junshan island in the past.


    "Academician, Junshan island is in front of us. According to the trace we traced, the unknown creatures should have come from the island!" The scouts in the team report to Chen Xin.


    "It seems that changes have taken place on the island that we don''t know..." after hearing what the Scout said, Chen Xin thought for a moment, and then said in the communication channel, "call the air force and let them send helicopters to investigate the whole Junshan island from the air. I want to know what happened on the island!"


    Chen Xin did not rashly take the combat team to the island. When the situation on the island is not clear, it is the safest way to let the helicopter conduct aerial investigation first and confirm the general situation.


    If there is any danger on the island that they can''t solve, and the whole combat team is in danger, that is the most stupid way.


    Of course, if the helicopter''s aerial investigation can not find any abnormality, they must also be duty bound to land on the island and find out what happened on the island.

 Chapter 643

    After half an hour of intense waiting, the results of aerial investigation came.


    On the island, the helicopter did not find anything unusual. It just found a cave, which could be the nest of unknown creatures.


    The failure of air investigation naturally means that Chen Xin and Chen Xin have to land on the island.


    At this time, the follow-up support also arrived with the help of transport helicopters dispatched by the air force, and a temporary camp was built near Junshan island.


    Inside the temporary command post in the camp, Chen Xin and others are analyzing the photos taken by the helicopter from the air.


    Because the island has also been hit by meteorites, Junshan island now looks more like the surface of the moon. There are several small craters around a large crater. Although it is covered with snow, we can still see the traces after the meteorites hit.


    On the wall of the pit, there is a quite obvious hole. In this photo taken from the air by helicopter, the black hole is really quite different from the gray snow around it.


    The cave does not look small, and it is slanting downward. Even if the helicopter approaches the cave and shines in with a searchlight, the cave is dark and seems to be quite deep.


    "From the photos, it is obvious that the unknown creature came out of this cave, and there should be more than one. There are many footprints around the cave, which is not like that left by a wild animal." The biologists who arrived later looked at the footprints in the photos and carefully analyzed them: "but it''s strange that these footprints only go around a few times and then return to the cave. Only one footprints leads to the outside. If it''s a group of wild animals, it shouldn''t be such a living habit."


    As for the biologists'' doubts, Chen Xin just said to him: "what we are going to face is probably alien creatures. To analyze it with the habits of earth creatures will only mislead us. Moreover, I think it is not wild animals, but intelligent alien creatures."


    "Do you have some wisdom?" Hearing Chen Xin say so, the biologist thought for a while and nodded: "if it is an alien creature, then everything is unknown. We really can''t use the biological habits on earth to analyze. But if that''s the case, we need more information, otherwise we can only make blind guess here. "


    "So we have to go to the island and go into the caves to find out." Chen Xin knocked hard on the table, looked at the officer and asked him, "how much power can we use now?"


    "There is a special team that has arrived at the temporary camp. Academician, you bring a Titan combat team, plus a Marine Regiment. In addition, the air force can send an aviation regiment to bomb here at any time, and the rocket army will also provide firepower support for us when necessary." After a little calculation, the officer answered Chen Xin''s question.


    Hearing the officers say that so much force can be used at present, Chen Xin is a little relieved that he has so much power in his hand. Even if it is an alien invasion, he can solve the problem by direct strategic bombing.


    But after thinking about it for a while, he still didn''t ask people to bomb directly. Instead, he said to the officer, "let the special forces and Titans get ready and go to the island first to see what''s going on. If we can solve the problem, we don''t need to bomb."


    The officer nodded and affirmed Chen Xin''s decision, but he also asked Chen Xin, "what if the problem can''t be solved?"


    "Poor is tactical, rich is..." Chen Xin said here, his right hand into a fist, directly hit in front of the photo and map: "strategic bombing."


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    With the command of the battle issued, the special forces who were temporarily dispatched were ready to follow the eight Titans to mount Junshan island and enter the discovered cave.


    The space inside the cave is not small. At least eight Titans entered the cave smoothly.


    And as they gradually descended and reached the interior of the cave, the height of the cave became higher and higher.


    "The cave should have been excavated on the basis of natural caves. There are traces of excavation on the walls of the cave." After going deep into the cave for a period of time, Chen Xin found many new clues.


    "It''s a trace of excavation, but what is it made of? There is no organ on the body of that creature that can excavate the rock wall! " Biologists who keep in touch with Chen Xin can''t figure out how the creature dug through the pictures taken by Bai long. It''s obvious that its claws are not designed for digging.


    Chen Xin has some speculations about this, but he hopes his speculations will not come true. However, he still said: "they are likely to be social structures similar to ants and bees, with worker bees or worker ants. The creature we met before may play the role of soldier ants."


    "If so, it can explain their strange behavior." The biologist nodded, thinking about the probability of this possibility.


    "Now I''m worried about whether the bombing will work. The hole is so deep that we should be under the lake now. I''m afraid the bomb won''t blow in." Chen Xin is worried about another thing.


    "Academician, you don''t have to worry about this problem. The air force has prepared ground penetrating bombs, and the engineers have prepared to blast at the entrance of the cave." The officer on one side said so, obviously they had plans for some things.


    Hearing that there were already engineers in preparation at the entrance of the cave, Chen Xin''s worries did not ease.


    After all, it is not clear what these creatures are. Since they can excavate this cave, it undoubtedly proves that they have the ability to excavate. Simply blasting the cave will not play any role.


    But it''s no use worrying about them now. What''s more important is to find the nest that can be identified as an alien creature and find out what''s going on.


    As for how to deal with them, that''s the next thing.


    As Chen Xin went deeper and deeper, they finally found the nests of those alien creatures, and everything that appeared in front of them stunned everyone.


    Looking at the nest in front of him, Chen Xin finally understood why the creature he met had a body temperature of 105 ¡æ, because these guys actually dug out the magma directly, relying on the heat of the magma as their own energy source!


    Deep in the cave, there is a pool like magma pool, in which dark red magma is accumulated, while a huge and bloated monster lies beside the magma pool. The bloated body is almost translucent, emitting an unknown orange red light.


    And the same individual as the creature Chen Xin encountered before is sitting around the monster, supervising other smaller individuals to dig the cave.

 Chapter 644

    The bodies of these alien creatures were transported out of the cave, and the cave collapsed directly after Chen Xin discussed with the commanding officer.


    Although he has killed all the alien creatures he encountered and searched the cave to make sure there are no missing ones, Chen Xin is still worried that there are still fish who have missed the net.


    After all, this is an alien creature that no one has ever seen, and no one can guarantee that these alien creatures will be killed, or only this group.


    But in any case, to be able to clean up these alien creatures is also a solution to a huge hidden danger.


    After recovering all the corpses of alien creatures, biologists dissected the corpses of these alien creatures and found a large number of daughter embryos in the mother''s body. They also found more than 50 young embryos in the cave.


    Obviously, these alien creatures are breeding in large numbers.


    Chen Xin is not clear about the ecological habits of this alien creature, but no matter what the living habits are, they can reproduce in such a large number, and their individual strength is so strong that even if they are ordinary beasts, they are enough to pose a great threat to human beings.


    Especially in the battle, Chen Xin saw with his own eyes a combat sub body burst into the team of special combat team members, causing several people injured in just a few seconds.


    Professional soldiers equipped with powered exoskeletons are hard to confront the fighting offspring of this alien creature. It can be imagined that ordinary people who have no fighting ability will encounter what kind of terrible consequences this alien creature will have.


    So even if there are living samples to better study the habits of this creature, Chen Xin also has the ability to capture living samples, but Chen Xin still ordered to kill all the alien individuals and destroy all the young embryos.


    Even in order to prevent future trouble, Chen Xin asked Qin LAN to shoot the young embryos of alien creatures with Zhu Luan''s plasma gun. He destroyed all the embryos with high-temperature plasma and turned them into a pile of coke.


    Not only that, Chen Xin also issued a strict order to destroy all the remains of alien creatures at the scene, leaving only the mother, several combat Progenies and another seed body as samples for research.


    Originally, Chen Xin wanted to destroy all of them, but considering that this alien creature may still exist, it is necessary to study their biological habits, and then he left some samples for research.


    Even these samples, Chen Xin also let Qin LAN personally stare, to ensure that all samples are under control.


    Maybe it''s because of all kinds of sci-fi movies. Chen Xin is really afraid of someone''s death and wants to cultivate or control this alien creature, which will lead to serious consequences.


    Fortunately, Yanguo''s high-level officials are not the brainwrecks in the movies. They don''t want to fantasize about the idea of controlling alien creatures after research, and they don''t have any messy ambitions.


    After understanding the whole story of the incident, the high-level officials fully respected Chen Xin''s opinions. They not only asked the soldiers to destroy all the bodies of alien creatures in strict accordance with Chen Xin''s suggestions, leaving only some samples for research, but also specially asked the military to send a troop to stay near Junshan Island to prevent alien creatures from escaping.


    And all the biological samples were not transported away. They were all sent to Chen Xin''s scientific research center on the principle of proximity, where they were directly studied.


    In order to study these alien biological samples, the state has sent biological experts in related fields, but it has strict requirements on them. All research on alien organisms must be carried out in accordance with the safety regulations, and any research that violates the regulations or exceeds the limits is strictly prohibited.


    In order to ensure absolute safety.


    Chen Xin naturally fully supports this. For the bodies of these alien creatures, he specially asked people to prepare a separate laboratory. He also put the three machine armours of Bai Long, Zhu Luan and Lu Shu beside the laboratory. In case of any accident, he directly destroyed the laboratory and all the biological samples with the three machine armours.


    As for Chen Xin''s arrangement, although some biologists complain a little, they think it''s a bit of a fuss. After all, what Chen Xin demands is that no matter whether someone is in the laboratory or not, if there is an uncontrollable consequence, even people will destroy the laboratory together. But these biologists also support his caution and caution.


    In the laboratory, several biologists dissected the combat progeny first.


    In addition to the fact that Chen Xin first encountered this kind of progeny and knew it best, there was also a sample in the laboratory that had been killed by Chen Xin before. Relatively speaking, the number of samples studied was the largest, so we need not be so careful.

 Chapter 645

    By dissecting and studying the collected biological samples, Chen Xin and biologists finally have a certain understanding of this alien creature.


    This is a very strange creature, with a colony structure similar to ant colony or bee colony. The division of labor between individuals is clear, and even there are huge differences in body size.


    If not for the discovery of a large number of embryos in the nest and in the mother''s body that have not yet been fully hatched, but have already possessed the basic morphology, Chen Xin could not believe that the two seed bodies with such great individual differences would be the same organism.


    At present, there are four kinds of individuals found in this alien creature. The first one is Chen Xin, the giant mother they saw in the cave. This monster''s body length is more than 10 meters. Although a lot of biomass inside the body has been lost after being killed, it is estimated that it weighs more than 30 tons in good condition.


    However, although the mother is huge, she has no mobility. Although she has a large number of walking limbs under her body, just like the queen, she has basically lost her mobility and become a huge reproductive machine.


    A biologist who participated in the research thinks that this kind of mother may be very similar to the queen of ant colony. Before the birth of offspring, the body is not so heavy and huge, but after arriving at the nest, the body will have a certain degree of changes, such as the expansion and development of genital organs used to cultivate offspring, so that a large number of offspring and offspring can be produced.


    After discussion with other biologists, Chen Xin thinks it is possible.


    Because more than two-thirds of the mother''s body is inflated to the exaggerated abdomen, not only the whole body is almost translucent, but it is also filled with a lot of liquid and daughter embryos. More than half of the weight of more than 30 tons is this huge abdomen.


    Naturally, there is more information about maternal anatomy than that, and Chen Xin is most concerned about the brain of this thing.


    As we all know, intelligence quotient of biology is closely related to brain capacity. Although it is not absolutely said that animals with larger brain capacity will be smarter, larger brain capacity means more brain cells, which naturally means more space to build more complex neural networks.


    After being dissected, Chen Xin and biologists are presented with a brain weighing more than 100 kg.


    Although it''s not unusual for a monster weighing more than 30 tons to have such a big brain, after rigorous analysis, the mother has extremely high intelligence, and can even control and command all her offspring.


    What''s more surprising is that the mother''s command and control of the offspring does not rely on the pheromone commonly used by ant colony or bee colony, but on the bioelectrical signal.


    Near their mother''s brain, Chen Xin found a special organ, which can generate electromagnetic waves in the form of biological discharge, thus transmitting radio wave signals, such as radio.


    This great earthquake shocked Chen Xin and biologists, but also shocked all people who understand this fact.


    Biological radio, it seems that no species on the blue star has evolved such exaggerated organs, and it''s really unnecessary for animals.


    After all, the transmission of information between animals is not too complicated. The combination of pheromones, body movements and calls is enough to transmit all the information.


    But a biological radio? How on earth did this evolve? Why did this species evolve such a set of information transmitting organs? What''s the matter with the environment they live in, and they need to transmit information in this way?


    However, through the dissection of other progenies, Chen Xin and others suspect that this kind of creature is likely to be a population with certain wisdom, and they can communicate through radio waves to form a whole.


    This is not like the existence of lions or monkeys, but the structure of ant colony and bee colony, with a more efficient way of communication, and individuals with a certain amount of wisdom


    This makes Chen Xin wonder if this kind of creature has already begun to evolve towards the swarm of insects in science fiction.


    Although there is no evidence, after dissecting all the biological individuals, Chen Xin is more and more worried that his worry will come true.


    Among the other three seed bodies of this alien creature, Chen Xin has encountered combat progenies. The surface of the body is covered with a thick chitin skeleton, which has a strong defensive force. At the same time, the body structure is similar to that of cats, with strong flexibility, movement speed and strength. At the same time, there are a lot of combat progenies, some of which are similar to the existence of soldier ants in ant colony.


    The other is Chen Xin''s offspring, which are similar to those of worker ants or worker bees. They are only half the size of their fighting offspring, and their chitin bones are not so thick and strong. However, they have a pair of insect like forelimbs, which can dig and pop up quickly like a shrimp, It looks like a combination of a hammer and a shovel.


    After seeing this kind of sub body, Chen Xin gradually understood why there were traces of excavation in the cave. Obviously, the cave was excavated little by little by this kind of sub body.


    As for the fourth seed Chen Xin, they did not find a living body. The only individual sample was an immature embryo taken from the mother''s body.


    The size of this embryo is very large, more than three times that of the other two seed embryos, which once led Chen Xin and biologists to think that it was the mother''s embryo.


    But the final anatomy and research found that this is an unknown fourth seed body.


    What exactly is the use of this daughter? We have different opinions, because the information we have on hand is too little, and now they are just beginning to study it. Obviously, it will take more time to decipher all the information.


    Just when Chen Xin arranged for the scientific research center to set up a project for these biologists to continue to study these alien creatures, news came from Junshan island that the military had bombed the whole island.


    This made Chen Xin suddenly surprised.


    Although they did apply for air support at that time and were ready to carry out strategic bombing, after clearing all the progenies in the cave, they had already wiped out these alien creatures, so the air bombing had been cancelled at that time. How come now that the corpses have been pulled back for autopsy and the army has started bombing?


    Just when Chen Xin was puzzled, more information came, and he was shocked.


    New caves and tunnels appeared on Junshan Island, from which a large number of combat progenies poured out, which forced the military to carry out large-scale bombing to eliminate these alien creatures.


    Moreover, it is not only Junshan Island, but also many places in the whole Dongting Lake area, where there are also traces of alien creatures, which have been inundated.


    www.novelhall.com , the fastest update of the webnovel!

 Chapter 646

    The whole coast of Dongting Lake has been in a state of emergency. Alien creatures have sprung up from various places around Dongting Lake, just like mushrooms growing in the ground. All of a sudden, they are overflowing and everywhere.


    If Chen Xin hadn''t discovered the trace of this alien creature before, and informed the military to be on guard, I''m afraid these alien creatures would have broken through the defense line and started to march into the cities around Dongting Lake.


    But even so, the military is still very difficult to resist these alien creatures.


    On the one hand, the individual strength of alien creatures is strong. Even if the ordinary soldiers are equipped with exoskeletons, it is difficult to confront them head-on. At least several soldiers need to work together to kill a combat daughter.


    On the other hand, it is also because of the large number of these alien creatures, and they attack from underground.


    In the process of attack, this kind of alien creatures show extremely high intelligence. When they are bombed by the air force, they will quickly drill into the ground to resist the air attack. When they encounter strong defense resistance, they will want to dig a passage through the ground to attack behind the defense line.


    Although this is not too difficult for the military to cope with, it still caused considerable trouble and brought a lot of casualties.


    If it was not for the timely support of the subsequent armored forces to stabilize the defense line, I am afraid these alien creatures would cause more damage.


    Even so, when these alien creatures like ants began to blossom along the coast of Dongting Lake, the military did not have enough troops to build strong defense lines everywhere to resist their invasion.


    After all, Dongting Lake is located in the inland area, which can be regarded as the hinterland of Yan state. Even if the military has troops around, it is only a small number of garrisons, but not the main force of the general.


    If we had not received the notice and warning of Chen Xin''s discovery of alien creatures before, and the military had mobilized part of the army, I am afraid the alien creatures would have broken through the defense line long ago.


    Even so, the military is now using high-intensity air force bombing to curb the spread of alien creatures, in order to gain time to mobilize troops.


    Hearing this news, Chen Xin felt as if his head had been hit with a stick.


    Originally thought that it was just a group of alien creatures that accidentally fell on the blue star. After destroying all the individuals, they had already solved this incident. However, they did not expect that they had actually multiplied underground into a large scale. Now they are bursting out because of their own actions.


    This makes Chen Xin even feel that he is the culprit of this disaster. If he is not so radical, he should first study the combat daughter who attacked him, analyze the situation clearly, and then go to exterminate these alien creatures, so that the military can make sufficient preparations. Would it not be so troublesome now?


    However, this idea only existed in Chen Xin''s mind, and was dispelled by him for a moment.


    Even if this is the case, he doesn''t want to think about what it is. Now the only thing he needs to do is to find a way to help the military defeat these alien creatures. Chen Xin doesn''t want to know how these alien creatures spread to the whole Dongting Lake.


    He just wanted to know how to effectively kill these alien creatures and how to thoroughly solve them.


    For the current situation, Chen Xin has something to support the battlefield. Although he wants to drive the white dragon to the front line to resist alien invasion, this time he is stopped and forbidden to go to the front line by the high level.


    Before that, he thought it was not so dangerous. Chen Xin had the white dragon Titan in his hand, and the extraterrestrial creatures really could not threaten his safety.


    But the battlefield is different. In such an environment, even if Chen Xin has a white dragon Titan, it can''t guarantee absolute safety, not to mention the new offspring of those alien creatures that have the ability to destroy Titan.


    Before Chen Xin, they did not understand what the role of the fourth seed is reflected in the battlefield to show their role.


    This is a kind of daughter that can emit high-temperature body fluid vesicles. They look like a hermit crab with a spiral case on its back, but their back is not a spiral case, but a huge vesicle like organ, which can throw the vesicles formed in the body, which are composed of highly corrosive high-temperature body fluid, onto the human position, causing great damage.


    The high corrosiveness of this high temperature body fluid can even corrode the armor of tanks and Titans, and cause great damage to vehicles and unprotected personnel.


    Fortunately, the speed of this kind of progeny to launch the vesicles is very slow, so that the soldiers have enough time to avoid or shoot the vesicles with guns, which did not cause more damage. But even so, at the beginning, they lost several Titans and tanks that could not avoid.


    Now the whole front is showing a sticky situation. The number of alien creatures is extremely large, and they are not pure wild animals. Although they have a certain wisdom, they can''t compare with human beings, they still show some simple tactics.


    It can even be said that fighting with human beings comes and goes, and even occupies a certain advantage in the battlefield.


    In such a situation, on the one hand, the military is constantly mobilizing new troops to the front line to fight against the invasion of alien creatures; on the other hand, it is constantly using artillery, missiles and air force bombing to curb the expansion of alien creatures.


    Although it is still able to maintain the front, and with the arrival of reinforcements, the front is constantly stable, Chen Xin is worried that these alien creatures will emerge from other places.


    Moreover, ordinary soldiers don''t have enough advantages against this alien creature, which is one of the reasons why the military is at a disadvantage on the battlefield.


    The military now needs equipment that can withstand alien attacks on the battlefield and help stabilize the front.


    Of course, Chen Xin is able to make such equipment. It''s only temporary, and it''s just a drop in the bucket. In a battlefield of this scale, a single piece of equipment can''t turn the war around, unless it''s a big killer like an atomic bomb.


    However, it is obvious that the high-level officials do not want to use such things at present. They are still using conventional force.


    Chen Xin can''t help but feel annoyed. If he had completed the design of the self-discipline Titan earlier, now he could pull out 180 self-discipline Titans to support the front line at any time, and the military would not be in such a passive situation.


    However, it''s not too late to mend. Chen Xin quickly upgraded the self-discipline Titan in his laboratory to the point where it can be put into actual combat, and copied the artificial intelligence carried in it, so that the factory began to produce this self-discipline weapon that can fight on its own.


    At the same time, Chen Xin is seriously thinking about how to create greater advantages for the military on the battlefield.

    In the city, there are shuttling vehicles and passing troops everywhere.


    Because of approaching the front line of the battle, it has become a war zone. After the troops and various materials from the rear are transported to the railway station, they will be quickly unloaded and then distributed to the places where they are most needed.


    Because the lake area is a war zone, even in the urban area, you can still hear explosions and gunfire from afar.


    For this country and this land, the last time there was gunfire, gunfire and war was decades ago. Up to now, few people have the memory of war, as if the war had been far away from their lives.


    But with the continuous sound of the explosion, the army walking through the city, still let the people living in the city feel the pain of the war.


    Although the war has not yet burned them, and the front-line troops are fighting against the invasion of alien creatures, everyone who can feel the approaching war can clearly feel that their lives are under threat, while another group of people are fighting to protect their lives.


    This can''t help but make everyone secretly pray that this war can be ended earlier and life can return to peace.


    But it''s a pity that no God heard the prayer, or heard it and didn''t respond. The war is still going on, even spreading to cities.


    Although there is a distance between Junshan island and the urban area, the military has also arranged many defenses here to protect the lives of more than 100000 people in the city.


    But obviously, alien invasion is not so easy to stop.


    Perhaps these alien creatures on the ground will be blocked by the defense line constructed by the military, and then killed in front of the position by gunfire and bombing, but the underground workers'' ants have extended the battle line to the city.


    Fortunately, these monsters can''t gnaw through the reinforced concrete for a while and a half, and the sound of underground excavation is not small. After the first worker ant''s daughter broke a small shelter to make killing, each shelter has greatly increased its vigilance, and installed monitoring equipment to prevent these alien creatures from sneaking attack.


    However, although it is effective, it still can not hide the fact that alien invasion has invaded the city.


    Under such circumstances, the city government can only maintain the order of the shelter while applying to the higher authorities to move the people in the urban area.


    Naturally, the superior passed the municipal government''s application quickly, and planned to make all the cities along the Dongting Lake move together.


    Although the military is still fighting, and continues to cause effective damage to alien creatures, everyone knows that with alien creatures invading the city through underground excavation, the defense line can no longer limit these alien creatures.


    It''s only a matter of time before the alien creatures bypass the defense line and invade the city. If the military can not keep most of the alien creatures out of the defense line and move the people in the city, it will only be a massacre when the alien creatures bypass the defense line and wait for these people who have no resistance.


    With such a large population, migration is not an easy task. Even if the municipal government can organize such a large-scale migration, how to migrate and where to migrate are all huge problems.


    It''s not easy to resettle these 100000 people now. Even if a temporary camp is built, it won''t be able to be completed in a moment and a half.


    But even so, with the cooperation of the military, the municipal government is organizing the relocation, or evacuation.


    Resettlement can be considered later. Now it is important to withdraw the people first.


    In the temporary command post set up in the urban area, all kinds of voices are noisy. All people have to shout loudly to let others hear what they say.


    There is no way. The front is the battlefield. The roar of guns can already be heard here. All aspects of affairs need the coordination and command of the headquarters. When someone is talking all the time, the noise is inevitable.


    In front of the map, several staff officers and generals in charge of command are surrounded in front of the map. The blue line of defense marked on the map is like a dam, blocking the red line representing alien creatures in front of the city, but the red dot marked on the back indicates the position where alien creatures have penetrated.


    Looking at the increasing number of red spots in the rear cities, the general''s brow has become more and more wrinkled.


    "How long does it take to evacuate people from the city?" The general inquired to an official sent by the city government.


    "It''s expected to take at least 20 hours. Although we have plans, now the main transportation capacity of the city is used to support the battlefield. We need time to move people." The officer explained to the general with a bitter look on his face.


    According to their original plan, evacuation of the people in the city can be completed within 12 hours when the urban roads are unblocked and the railway station can be used. However, in such a chaotic situation in the city, it is really difficult to evacuate the people quickly.


    Twenty hours is already a very optimistic estimate. In fact, they originally expected that it would take at least one day, but now the 20 hours is the result of their death.


    "If the high-speed railway station is put back into operation, can it speed up the evacuation?" At this time, Chen Xin''s voice sounded in the headquarters.


    "Academician Chen, why are you here?" The general was surprised to see Chen Xin walking into the headquarters.


    "There are 20 self-discipline Titans coming out of the scientific research center to support the front line, so I came with them." Chen Xin gave a simple explanation, then skipped the topic and pulled the topic back to the main topic: "there are three railway stations in the city, the old railway station, the railway station and the high-speed railway station. The old railway station does not mention him. The high-speed railway station has not been put back into use since the meteorite impact. The municipal government only guarantees that the original railway station can be used. Now if the high-speed railway station is put back into operation, Can you speed up your evacuation? "


    Hearing Chen Xin''s question, the city government official quickly calculated it and nodded his head and said, "if the high-speed railway station can be used, as long as the evacuation train stops at the high-speed railway station, the people can be transported away quickly, which can greatly shorten our evacuation time!"


    "OK, in that case, give me two hours, I will resume the operation of the high-speed railway station, and you will withdraw the people to the high-speed railway station." When Chen Xin heard the official say so, he made sure.

 Chapter 648

    Qin LAN and Mo Qingyan are driving their bodies at the original location of the high-speed railway station. According to Chen Xin''s instructions, the equipment Chen Xin gave them is arranged around the original high-speed railway station.


    Although they really want to go to the battlefield and support the front line with Zhu Luan''s powerful body performance, at Chen Xin''s request, Qin LAN and Mo Qingyan come here to set up the de icing equipment he made according to Chen Xin''s request, so as to enable the high-speed railway station to resume operation.


    Take down a deicing device from the back of the mechanical hound next to him, unfold it in the way Chen Xin said, and insert it into the snow. After Zhu Luan''s artificial intelligence inspection, he confirms that the device has started and the connection is normal. Qin LAN then rushes to the next preset position.


    On the other hand, Lushu, driven by Mo Qingyan, is doing the same thing, just because Lushu itself is a four legged body, and all the de icing equipment is carried on the back of Lushu''s body.


    "Alan, I''ve finished the work here. How many people are left on your side?" Insert the last deicing device on the back of Lushu into the snow. Mo Qingyan calls Qin LAN on the communication channel.


    "There are the last three left. Sure enough, four legs are faster than two legs!" Qin LAN replied in the communication channel, and also said to Mo Qingyan: "Qingyan, Lu Shu is faster. You can check again whether all the devices are connected, and there are no omissions."


    "I see. I''m checking." Mo Qingyan heard Qin Lan''s words, and immediately began to check.


    She also knows the importance of what they are doing now.


    The equipment they are setting up was made by Chen Xin when he knew that the city government was going to evacuate the people. According to Chen Xin, the equipment is set around the high-speed railway station, and as long as it is started, it can melt all the snow buried in the high-speed railway station within two hours.


    Although it sounds like a black technology, but with the trust in Chen Xin, the two girls still drive their own bodies according to Chen Xin''s requirements and come to the location of the high-speed railway station with the de icing equipment Chen Xin gave them. They set up the de icing equipment according to the coordinates Chen Xin gave in advance.


    But when they set up the deicing equipment, they were still worried. On the one hand, they were worried about the safety of the city. On the other hand, they were worried about whether Chen Xin''s equipment could work. What''s more, only melting the snow at the high-speed railway station would not work, and more importantly, melting the snow on the railway.


    After Mo Qingyan checks all the installed equipment again and confirms that they are connected and working properly, Qin Lan also completes all the work and comes to join her.


    After they got together, they felt a little uneasy. While waiting for Chen Xin''s arrival, they also talked about it in the communication channel to ease their own tension.


    "Ah LAN, when can ah Xin come over?" Mo Qingyan asks Qin LAN.


    Chen Xin didn''t drive the white dragon when he went to the city to see off the self disciplined Titan. Because of the high-level ban on him going to the battlefield, Chen Xin had to go to the headquarters by car under heavy protection, which made it difficult for Qin LAN and Mo Qingyan to get in touch with Chen Xin for a while.


    "Ah Xin said that he went to the headquarters to transport self disciplined Titans and inform them about the high-speed railway station. In a short time, he should be back soon?" Qin LAN is not sure about this. Although Chen Xin told them what they wanted to do before, waiting at this time still makes them feel a little anxious.


    Normally, as a sniper, Qin Lan''s greatest need is patience, but at this moment, she is a little restless.


    On the other side of the city is the battlefield. As a soldier, she hopes that she can kill the enemy on the battlefield at this time, rather than that other people are fighting desperately and preparing to leave in the rear.


    But Qin Lan also understood that in the case of being unable to prevent alien creatures from invading from the underground, the most important thing is to ensure the safety of people''s lives and property.


    But this still can''t calm Qin Lan''s mood. She still hopes that she can join the war in a more direct way.


    However, it''s just an idea and impulse. Qin LAN still understands that the most important thing for her now is to do well the task Chen Xin assigned to her and Mo Qingyan, so as to ensure the smooth re operation of the high-speed railway station.


    At this time, Mo Qingyan suddenly asked, "speaking up, why don''t a Xin Let us start the de icing equipment? It''s going to take time for him to come, isn''t it


    "I don''t know, but a Xin should have his own consideration? Or are you worried that we won''t be able to operate the equipment, or that we will miss the work? " Qin LAN guessed, not sure why Chen Xin didn''t let them start the de icing equipment to save time.


    Just as they were waiting for Chen Xin to return, Chen Xin''s voice finally rang out in the communication channel: "a LAN, Qing Yan, is the deicing equipment ready?"


    "It has been arranged. When will you come, ah Xin?" Qin LAN reports to Chen Xin and cares when he can come.


    "I''m on my way. You two go home and ask Han Ping and Han Ze to protect my parents and prepare to leave with the people in the scientific research center. You two will also leave with the people in the scientific research center. The Titans over there have been sent to the front line. Although there are special forces to protect them, the two titans over there are still safer." Chen Xin tells Qin LAN and Mo Qingyan to evacuate and protect his parents.


    Although the scientific research center is outside the urban area and protected by special forces, it is still too close to the urban area. Even though the urban area has begun to be infiltrated by alien creatures, it is not safe here.


    The whole city has to be evacuated, and the scientific research center is no exception.


    "What about your side?" Mo Qingyan interjected in the communication channel.


    "Don''t worry, I''ve asked my sister to send my white dragon. With white dragon, my safety is not a problem." Chen Xin explains to Mo Qingyan.


    Qin LAN and Mo Qingyan both know that this is not the time to argue with Chen Xin. Although they are very worried about him, they can only say "be more careful" and return to the research center according to Chen Xin''s instructions.


    Not long after they left, Chen Xin came here under the protection of a special combat team, and the white dragon sent by Tang Tang also arrived in front of him.


    Chen Xin did not immediately board Bailong, but started the de icing equipment first.


    This set of deicing equipment, which he temporarily destroyed a large amount of survival, is the key to the general''s guarantee that the high-speed railway station will resume operation in two hours.


    With the start of the deicing equipment, a light blue energy field visible to the naked eye covers the whole location of the original high-speed railway station, and the internal temperature of the energy field begins to rise rapidly, a huge amount of water vapor is evaporating, and the snow on the ground is also melting visible to the naked eye.

 Chapter 649

    Of course, this set of de icing equipment was made by Chen Xin through system upgrading, but in order to achieve the best effect, he also lost a lot of survival.


    So this set of equipment can melt the snow covering the whole station in just two hours, making the original high-speed railway station exposed.


    When Chen Xin thaws the snow at the high-speed railway station, other parties are also moving quickly.


    The city government has sent all the staff and is evacuating all the people in the shelters. Although the loss of abandoning a city is considerable, compared with the life and death of more than 100000 people, it is obvious that human life is more important.


    Fortunately, after the initial cataclysm, the people who can survive have long been used to order and are ready for the transfer under the official organization.


    When the municipal government organizes the evacuation, the military invests all its strength in the front line, and strives to delay as much as possible, so as to ensure the smooth evacuation of the rear cities.


    Not only that, in order to ensure the safety of the evacuation operation, the military also deployed an elite patrol in the city, specially responsible for dealing with those alien creatures who infiltrated into the city by digging.


    This elite is equipped with heavy machine armour, even if it is one-on-one against alien creatures, it is not without the power of World War I. with their heavy machine guns, it can still cause effective damage to alien creatures.


    Although it is difficult to contain the alien invasion on the frontal battlefield due to the large number of alien creatures, it is still no problem to deal with the small infiltrating enemies in the urban environment.


    As a matter of fact, the military has been extremely subdued in this battle.


    Although preparations were made at the beginning, at the beginning, the military thought that it was just an island problem. It did not expect that the alien creatures would have such a large scale, so the military strength mobilized was not enough.


    Although the follow-up reinforcements also arrived soon, the whole defense line was suppressed by alien creatures because it lost the advantage at the beginning.


    The surprise attack, which was originally our first advantage, turned into an encounter. Around the lakeshore, where there was no natural danger to defend, we had to build a hard stronghold and fight in a daze.


    Even though the air force''s bombing has achieved certain advantages, the follow-up heavy firepower will be launched and the front line will be stabilized, but the ability of extraterrestrial creatures to dig the ground makes the military become powerful, and it can only watch the extraterrestrial creatures infiltrate into the city from the underground.


    This makes the military feel like a giant with a hammer, while these alien creatures are hamsters in the earth. Although the risers are about to be knocked to death, the military can only knock them to death after they rise, and can''t stop them.


    It''s not that the military didn''t want to use the ground penetrating bomb to directly attack the underground, but the surface of the lake area is covered with snow, and there is ice more than ten meters deep down. It''s only the soil layer that has been dug up. Even if the ground penetrating bomb is used, it doesn''t have a good effect.


    After all, the nest Chen Xin discovered was at least 100 meters deep underground. Even if the earth penetrating bomb could reach such a depth, it would be difficult to cause effective killing.


    It''s not that the military didn''t want to organize elite forces to break into the ground and destroy the alien nest like Chen Xin did before. But after one attempt, the military had no choice but to give up the idea.


    However, the underground passages of these cities are very narrow. In terms of the size of alien creatures, only worker ants can pass smoothly, and human beings will be greatly restricted after entering.


    In such a situation, even with the most advanced equipment, it is difficult for the soldiers to display their own advantages. In this cave environment, it is easy to fall into the enemy''s numerical advantage.


    So after several attempts, the military had no choice but to give up the plan to destroy these alien creatures and change its combat strategy to delay the evacuation of the people.


    After all, in addition to soldiers equipped with heavy machine armour can form an advantage over alien creatures, the exoskeletons of ordinary soldiers can only rely on the enhancement brought by quantity and weapons to resist alien creatures. Heavy equipment such as tanks, artillery and Titans can not go deep underground, so it is difficult to complete the clearance of alien creatures.


    In fact, if it were not for the fact that the nests of these alien creatures were underground and kept flowing like a tide, they would have been wiped out by the military.


    But in the face of the alien creatures hiding in the tunnel, not fighting head-on with the military, but infiltrating from the underground, the military is really powerless.


    Fortunately, in the face of this kind of disaster, everyone knows the priority of things, and the evacuation work went very smoothly.


    When Chen Xin was melting the snow at the high-speed railway station, the first batch of evacuated personnel had arrived at the high-speed railway station, and the scientific research center had packed all the important materials and was preparing to evacuate.


    Although the time is pressing, when evacuating, we should carry only the most important things as far as possible, but there are too many important things in the scientific research center. Even if they are the first to receive the evacuation message, they still spend a lot of time to transfer these important materials and equipment.


    Chen Xin''s parents have received the words from Qin LAN and Mo Qingyan, but they are not too nervous. They just ask Han Ping and Han Ze to help them pack up, and they are preparing to leave with the people in the research center together with Qin LAN and Mo Qingyan.


    At this time, Chen Xin''s parents seemed calm and calm. They didn''t get into a panic because of the need to evacuate. They didn''t even care about the jars at home. They just asked Han Ping and Han Ze to help them pack up some clothes to wear, take some important things with them, and didn''t take other things.


    Qin LAN and Mo Qingyan are also picking up their things, but their things have been almost cleaned up by Mo Qingxin. As long as they take some important personal belongings, they can leave.


    "It''s a pity that my wine has been drunk by ah Xin for a long time, so I can''t waste it like this." Mo Qingyan still has some regrets about her wine. Although she knows that this refuge should not be broken by alien creatures, she still regrets her collection which was rescued before.


    After all, the whole city is evacuating, and no one knows when mankind will be able to recapture the city.


    "Don''t pity these things at this time. The whole city has been abandoned. Don''t care about these things. Just pack them up and go. It''s time to leave." Qin LAN can understand Mo Qingyan''s mood, but this time is not the time to tangle these.


    Mo Qingyan hears Qin LAN say so, although in the heart does not give up, but still nodded, took own some important personal belongings, then left the underground of the refuge with Qin LAN.

 Chapter 650

    When Qin LAN and Mo Qingyan arrived at the high-speed railway station driving the evacuation team of Titan escort Research Center, a large number of people waiting for evacuation had gathered here.


    Fortunately, there were staff at the scene to calm down and maintain order. Although there were a lot of people, they didn''t seem very confused.


    The team of the scientific research center was quickly arranged to a place to repair and wait for evacuation. While Tang Tang arranged for everyone to repair temporarily, he also asked Qin LAN and Mo Qingyan to go to Chen Xin and ask about the evacuation.


    Qin LAN asks Mo Qingyan to stay at the station, while she comes down from Zhu Luan. It takes a lot of effort to find Chen Xin in the station who is trying to repair the equipment in the station with several staff members.


    "Ah LAN? What are you doing here? What about the others? " Chen Xin saw Qin LAN appear, quickly asked a concerned.


    "The people of the scientific research center have withdrawn, and your parents are also here, but there are still some materials in the back. Director Tang sent some vehicles to transport them back." Qin LAN reports to Chen Xin what Tang Tang asked her to tell her. At the same time, she asks with concern: "ah Xin, can the high-speed railway station be used now? How do we evacuate so many people? I see snow on the railway line. Does it take time to clear it? "


    "Don''t worry. I''ve already arranged for the evacuation. I''ve done a lot of preparation before, and now I''ll just wait for the evacuation." Chen Xin didn''t worry about it and comforted Qin LAN.


    When he planned to use the high-speed railway station as the evacuation station, he had already made a plan. He not only prepared the deicing equipment for the high-speed railway station, but also contacted the vehicles for evacuation.


    As a matter of fact, Chen Xin has already arranged for the subsequent resettlement sites. Now he can evacuate only when the vehicles for evacuation arrive.


    Chen Xin didn''t talk with Qin LAN much. After understanding the situation, he asked Qin LAN and Mo Qingyan to guard around the station.


    Although alien creatures did not infiltrate here, but just in case, he still let the only two titans in the station patrol to ensure safety.


    As for his own white dragon, although he can also drive the white dragon to patrol, it is obvious that Chen Xin can play a better role in other aspects.


    So Chen Xin just let the white dragon start, and then the AI little white dragon controls it. He follows Qin LAN and Mo Qingyan on patrol, instead of driving by himself.


    "Academician, the damage of the line here is not very serious, but the whole power grid has collapsed, and the significance of repair is not great. We have checked the rail side, except for the snow covered part, the other parts are in good condition and can still be used now." A staff member reported the repair of the station to Chen Xin.


    If such a large high-speed railway station wants to be put back into use, it''s not just about melting the snow.


    Although the original vehicle dispatching equipment and the power supply network of high-speed rail lines have been unable to use, but the signal lights, road gates and other equipment are still in great need, and must be restored to a usable state.


    Chen Xin was surprised to hear the staff say that the rails could still be used.


    The city is located in the south, and the coldest temperature in winter is only ten degrees below zero. Therefore, the rail is not treated with special cold protection as the northern rail, but even so, the high-speed rail station, which has not been maintained and used since the disaster, can still be used, which makes Chen Xin surprised at the quality of the rail.


    However, since the rail can still be used, it will save a lot of effort. Chen Xin told the staff, "clear up the platform as soon as possible, and the express train I ordered should be coming soon."


    "Express train?" The staff didn''t understand the meaning of Chen Xin''s words, but they didn''t ask much. After all, although they didn''t understand, they still understood the meaning, that is, the train is coming.


    While the staff were busy, Chen Xin also received a communication that the "express train" he was waiting for had entered the urban area and was coming to the high-speed railway station.


    After receiving this news, Chen Xin also quickly asked the staff to arrange the first batch of evacuees to board the platform and prepare for the evacuation work.


    The first group of people who were ready to leave boarded the platform with anxiety. At this time, the sound of the train siren came from a distance, like the roar of a giant beast, but it brought hope to all.


    I saw a train push away the snow on the rail in a very rough way. From time to time, it whistled and drove into the station.


    The huge front of the car is equipped with a special snow remover. Even if the snow is higher than the car body, it doesn''t matter. In the Siberian wasteland, Chen Xin''s nuclear power train hard topped the snow.


    What Chen Xin called to evacuate the people was the mobile shelter composed of nuclear powered trains, which was used to transfer the victims during the southwest earthquake period.


    As the train stopped, the door opened and several soldiers came down from it. After handing over with the staff on the platform, they opened all the doors and let the staff organize the people on the platform to get on.


    Seeing that the people on the platform could not wait, but still kept order under the organization of the staff, they boarded the train in turn, Chen Xinxin''s worry was relieved.


    In order to successfully evacuate more than 100000 people from the urban area, Chen Xin mobilized all the mobile shelters that he could get to within the specified time through the high-level management. A total of eight nuclear powered trains were enough to transfer everyone safely.


    With the arrival of the first nuclear power train, other trains have entered the high-speed railway station.


    Soon, the three platforms and four tracks in the station stopped the train, and the first group of people organized also boarded the train at the fastest speed on the premise of maintaining order.


    With the help of some of the staff, the team of the scientific research center also transported all kinds of important materials to the already prepared freight cars.


    "Academician, your carriage is ready. Do you want to get on first?" A staff member approached Chen Xin and persuaded him to leave first.


    Chen Xin shook his head, thought about it for a while, said: "let my parents take my car to go first, I stay and wait for the car behind."


    It''s not that Chen Xin has a high mental consciousness and wants to get on the train last. It''s just that he arranged and designed the evacuation plan. He has to be responsible for it all. He has to make sure that at least most people can evacuate smoothly and the follow-up work can go smoothly without him.


    Otherwise, if there is any problem at the station, he can quickly solve it by upgrading the system. Without Chen Xin, ordinary people may have no way to deal with it, which will affect the subsequent evacuation work.


    Moreover, there are still a lot of things that have not arrived at the scientific research center, and some vehicles can''t follow the train. Obviously, it is necessary to organize the evacuation of the motorcade. Chen Xin also needs to be personally involved in the organization of these motorcades, so he really can''t leave at this time.

 Chapter 651

    The mobile refuge made up of nuclear powered trains is quite different from the last nuclear powered train Chen Xin saw in Southwest China.


    At that time, there were 27 cars in the nuclear power train, 20 of which were used to carry the victims, but because each car was a long sleeper car, only 90 people were carried in one car.


    So although there are 20 cars, they can only transport less than 2000 people at a time.


    At that time, because the resettlement of the victims went smoothly, and there were airbags to help transport the victims, it didn''t matter that the train could only transport so many people at a time.


    But now there are more than 100000 people waiting to be sent away. Although there are only a few thousand people on the three platforms, this is only the first batch of victims to be transported.


    Although there are eight nuclear powered trains in the mobile shelter, considering the total number of people who need to be moved, this efficiency is obviously not good.


    So this time, the carriage carried by the nuclear power train has also made considerable changes. It is not the sleeper carriage for long-term residence, but the double hard seat carriage for more people.


    Although it can''t make people live in the car for a long time, it can transport more people in a short time.


    Considering that this is an evacuation mission, it is the most important to be able to take more talents at one time, so it is inevitable to use the carriage that can carry more people.


    This kind of double deck car is one of the long cars developed after the nuclear power vehicle was put into use. The double deck hard seat can carry 220 people in total, and more people can be packed if necessary.


    A nuclear powered train as a mobile refuge can jam 5000 people.


    Under the arrangement of the staff, the first batch of evacuees on the platform quickly boarded the first train. After confirming that it was full, the nuclear power train, as a mobile refuge, drove out of the high-speed railway station and along the railway track to the predetermined resettlement site.


    Seeing a train leaving, Chen Xin was relieved. At this time, the people from the scientific research center and his parents had already boarded another nuclear power train. Relatively speaking, the conditions of this train were better.


    Considering the purpose of transporting scientific research instruments and these scientists, although the mobile shelter is also the same vehicle formation, it has two long sleeper cars and three freight cars, just for the people of the scientific research center.


    However, the scientific research center had too many things to take away, and three freight cars were soon filled, which made Tang Tang, who was responsible for organizing the transfer, a little worried and angry.


    She quickly found Chen Xin and reported the situation to him: "is it possible to transfer a new car now? We need at least two more cars to transport all the important materials that need to be loaded and transported away! "


    Faced with such a situation, Chen Xin also felt numb. After thinking about it, he could only say to Tang Tang Tang: "I''ll try my best to find a way. It''s really no good. You can go to the city government and let them find a way to make some space in the evacuation team. It''s really that they will be transported by car without a train."


    "That''s all we can do now! I''ll go to the city Tang Tang nodded. After all the people who needed to be transferred in the research center got on the train, what she needed to be responsible for was the transfer of these valuable materials.


    In a sense, these materials are even more important than the transferred researchers.


    So it''s no wonder Tang Tang Tang feels anxious and angry.


    Fortunately, things are going well. After Chen Xin contacted with other parties, another mobile shelter he has supported has arrived half an hour late as a price. That train will be equipped with two more carriages to carry away these important materials.


    Hearing this news, both Chen Xin and Tang Tang were relieved.


    While they were busy with these things, a new group of evacuees were also sent to the high-speed railway station.


    The number of this group of people is obviously several times more than that of the previous group. At least 20000 or 30000 people are crowded around the former high-speed railway station, which makes it crowded and noisy.


    Even if there are staff to maintain order, it''s a mess.


    After all, in the case of knowing that the alien invasion and the city will be abandoned, everyone hopes to evacuate earlier.


    In this situation, if you stay one more minute, you will be in danger.


    Although there are still troops fighting ahead to keep alien creatures out of the line of defense, this large-scale migration itself is still very easy to panic.


    At this time, the evacuation staff and Chen Xin can only arrange these people to board the other three trains which are also parked on the platform as far as possible, so that these people can evacuate as early as possible.


    It has to be said that even at this time, the staff of the municipal government are still doing their best to maintain order. Although more and more evacuees gather at the high-speed railway station, the chaos and noise are increasing, these staff are still trying to maintain order at an acceptable level.


    After the three trains parked on the platform were full of evacuees, the trains prepared by the municipal government for the evacuation plan were transferred one after another, and the people waiting for evacuation were stopped on the platform to board these trains symbolizing the hope of leaving.


    Looking at the people on the platform, although they seemed very anxious, there was no riot and fighting, Chen Xin still felt relieved.


    At this time, the staff of the municipal government also found Chen Xin and asked him about the resettlement of the people after the evacuation.


    Originally, the municipal government should be responsible for this, but before, the municipal government only prepared the evacuation plan. For example, the resettlement of more than 100000 people, without high-level coordination and planning, it was very difficult to do even before the disaster. In addition, the evacuation was very sudden, so the municipal government did not know the specific resettlement location.


    "The resettlement site for the evacuation was the Dome City in the previous planning. Originally, according to the planning, some people would move from the city to the past, but at that time, the consideration was to wait for the city to be built before moving, instead of being like now, just like escaping." Chen Xin shook his head helplessly.


    The foundation construction on the other side of the Dome City has been basically completed, even the dome has been built, the construction of the dome itself has been basically completed, and a considerable part of the internal buildings have been completed, and now the follow-up construction is in progress.


    Although it does not have the conditions to let more than 100000 people live in it, it is still OK to temporarily settle down and wait for the follow-up arrangements.


    After all, the dome, which is nearly finished, can keep warm from the cold and shelter from the wind and snow, compared with setting up tents directly in the field.

 Chapter 652

    The evacuation work has been carried out in a tense and orderly manner. Although there are more than 100000 people to be evacuated, fortunately, the municipal government has a pre prepared evacuation plan, so far there has been no problem.


    The military also relies on planting bombs in the evacuated shelters, and the air force uses ground penetrating bombs and other means to delay the alien invasion of the city as much as possible.


    On the whole, the current situation has finally stabilized.


    Although cities still have to give up, the fierce battle between humans and alien creatures has gradually become a drag on time.


    On the human side, there is no effective means to curb the underground offensive of alien creatures, so we have to give up the cities along Dongting Lake. On the other hand, the alien creatures are due to the huge casualties.


    Unlike the human side, where the armed forces rely on advanced equipment and do not suffer too much casualties, but consume a lot of ammunition, a large number of individuals have been wiped out in terms of alien creatures.


    Even though the social structure of this alien creature is similar to that of insect swarm, and the combat progeny and worker ant progeny at the bottom belong to cannon fodder and consumables, they have been heavily damaged by human carpet bombing before, and continued mass destruction after that, which still makes the alien creature consume a lot of troops.


    The success makes them from the original like flood surge, become now some successor powerless appearance.


    But that doesn''t mean alien life is not going to work.


    Although the loss of a large number of combat and worker ant progenies has weakened the population as a whole, the underground mother and hatchery have not been damaged. For the alien species, it is only the hatchery that needs to hatch a few more rounds if they want to replenish their forces.


    Especially when these alien creatures realize that they have lost a lot of individuals, and let the mother and the hatchery start to catalyze the hatching speed of their offspring, their replenishment speed will be faster.


    Although the incubation rate of the catalytic progeny will greatly shorten the life span of the progeny, and even affect the physical quality, it can replenish the number of the progeny in a short time.


    Since they are all thrown directly into the battlefield and live for less than three minutes, there is no difference between using cheap instant progeny and using more expensive standard progeny, right?


    Although they are just a group of alien creatures, there is a highly intelligent individual in their group. Even without human intelligence, they can quickly learn this truth on the battlefield.


    However, while continuing to add oil to the battlefield, the leader of this ethnic group is also gradually changing his strategy and starting to recover the corpses of the dead offspring from the battlefield to recover biomass.


    For this alien creature, fighting is actually a quality war. As long as there is enough biomass, the group can hatch a continuous stream of offspring and send them to the battlefield until the opponent is completely submerged.


    After all, for civilizations that are still on the planet''s surface, fighting mass wars is no match for their endless stream of creatures.


    In the memory inherited from the ethnic group''s genes, this ethnic group has invaded many living planets, relying on their amazing reproductive capacity and powerful combat effectiveness, and finally drowned the whole planet with offspring like a sea.


    But this time, there seems to be something wrong with the planet they chose. Not only is the whole planet covered with ice and snow, but the whole planet is also short of organic matter and biomass. As a result, the population can only convert energy by absorbing geothermal energy, which greatly weakens their expansion speed.


    In fact, if this group of alien creatures invades the blue star before the disaster, relying on their strong reproductive capacity, the biological invasion at this moment is not just a Dongting Lake area, but the entire Yangtze River Basin.


    This is not known to humans at this time, but with the further study of extraterrestrial organisms, they will know this sooner or later.


    As for how to completely eliminate these alien creatures and expel them from the blue star, even Chen Xin still has no idea at this time.


    Although it''s not that there is no way to completely exterminate these creatures, Chen Xin is still entangled with the things at hand at this time, and can''t spare time and think about how to exterminate these invasive alien creatures.


    While organizing the evacuation of cities around Dongting Lake, high-level officials are also seriously considering the possibility of using nuclear weapons in the lake area.


    After all, after the evacuation of the people around the city, the use of weapons of mass destruction such as nuclear weapons will be less restricted and restricted, so that the high-level can consider using them.


    However, at present, the high-level officials are not sure whether nuclear weapons can effectively kill and kill alien creatures. Considering the possible impact of using nuclear weapons in their own territory, the high-level officials have such an idea, but they are only prepared to use it as a last resort.


    At present, the high level still hopes to rely on the conventional military force to solve the problem of these alien creatures emerging from the ground.


    It''s just that although the military can stabilize its defense line on the frontal battlefield, it can''t effectively eliminate these alien creatures now.


    After getting the information that most of the people in the rear cities have completed the evacuation work, the military has no longer adopted the tactics of hard top, and began to gradually withdraw the defense line, reduce the intensity of shelling and bombing, and reduce the consumption of ammunition.


    Maintaining high-intensity air force bombing and shelling can indeed effectively kill alien creatures, but the consumption of ammunition behind this is also very amazing.


    Although many people make complaints about too many ammunition reserves, they have to destroy a lot of expired ammunition every year, but there is a logistic transportation replenishment process between the warehouse expired and the battlefield consumption.


    It''s really cool to blow up TMD in the front line, but the logistics is also a curse.


    Under normal circumstances, the better the front-line bombing, the louder the voice of the logistics curse, which is proportional to the two.


    After all, every bullet used in the front line needs to be transported by logistics.


    Even though the country has a fairly perfect and powerful logistics system, there is still a limit to the amount of ammunition that can be sent to the battlefield and front line in such a sudden large-scale war.


    After such a long period of high-intensity fighting, the ammunition carried by the troops on the defense line has basically been used up, and the ammunition sent by the logistics has also consumed a lot. On the whole, if we continue to maintain the previous high-intensity firepower, the consumption of ammunition will not be able to keep up.


    After all, most of the people in the city have evacuated, and the corresponding ammunition supply has also been affected.


    So the military decided to withdraw gradually after evaluating the situation on the battlefield.

 Chapter 653

    "Academician, this is the last group of people to leave." On the platform of the high-speed railway station, the staff organized the last batch of evacuees to board the train and report to Chen Xin.


    After more than ten hours of intense evacuation, there are only a few thousand people left on the platform.


    Now, no more than in the past, everyone is making a list at the shelter level, so there is no possibility that someone has left it out.


    After all, with the deterioration of the environment, people like Chen Xin who built their own shelters to survive are hard to persist in this harsh environment. They can only turn to the official shelters for help and go to the official shelters.


    Because of this reason, all the people in the urban area are under the control of the government, and no one will leave when evacuating. It is also relatively better to manage and control the order.


    After the last group of people were arranged to board the evacuation train, Chen Xin also let the last group of staff on the train.


    They evacuated the city, but the military continued to hold on.


    Evacuating people does not mean giving up the city completely.


    The reason for evacuating the people is that the city is close to the lake area, so it is too close to the front line of the battle. If there are a large number of people in the city, the military can not use powerful weapons, so it is very constrained.


    But now that the people have been withdrawn, the army can move the front back and rely on the city to build a more effective defense system.


    It''s not like now, in the open lake area and the hard work of alien creatures, we can only rely on heavy firepower to continuously suppress the large-scale attack of alien creatures.


    As for the attack of alien creatures digging underground, it is not that the military has no way to deal with it.


    In the past, it was only because of the inability to retreat, and the lake area, that many things on the temporary defense line were too late to be laid out and expanded, which gave the alien creatures an opportunity to take advantage of, and led to the situation that many parts of the military were in a passive situation.


    But now that the military''s worries have been solved, enough space has been made available for more effective defense, which undoubtedly greatly improves the military''s unfavorable situation against alien creatures on the front line.


    So when the city government organized the evacuation of the people, the military began to take over the city gradually and began to set up new defense lines.


    But now these things have nothing to do with Chen Xin. He had been busy with the evacuation before. Now he has finally dealt with these things. With his nerves relaxed, he just fell asleep on his seat.


    Seeing Chen Xin fall asleep on his seat, Tang Tang sighs a little when he looks like this. After getting a blanket, he carefully covers Chen Xin''s body.


    Qin LAN and Mo Qingyan have already taken care of his parents to evacuate, while Tang Tang has to deal with the evacuation of follow-up materials from the scientific research center, so he has stayed until the end, and now he is with Chen Xin.


    Looking at Chen Xin''s tired appearance, Tang Tang can''t help feeling some heartache, but also some nostalgia.


    She and Chen Xin are classmates. When they formed a club together, they had seen Chen Xinlei sleeping.


    However, Tang Tang at that time did not expect that in the future, they would meet with each other in such a relationship as they are now, and they would see Chen Xin fall asleep again in such a situation.


    Thinking of this, Tang Tang found the staff on the train and asked them, "how long does it take us to get to our destination?"


    "It will take about two hours. Several trains evacuated before are on this line. If they are successful, they can arrive quickly. But the station over there is a simple station with only one platform. It may take a lot of time to get in and get off." The staff answered to Tang Tang Tang.


    They have been several times to transport other evacuees before, and they still know about the situation at the resettlement site.


    Hearing what the staff said, Tang Tang nodded and didn''t ask anything else. He just asked where there was hot water on the bus. Then he went to pick up some hot water, took out a bag of dry powder from his luggage and poured it into the cup. After mixing with the hot water, he ate it.


    Most of the other people in the car are similar to Tang Tang at this time. They all take out some food from their bodies and eat it silently.


    I''ve been busy for more than ten hours. In fact, most of the staff have been hungry. Even the ordinary people who have been evacuated haven''t eaten anything because of their high mental stress. Now they are able to rest safely. Naturally, the first thing that people think of is eating.


    After having a full stomach, most people find it hard to hide their tiredness and find a comfortable position to rest.


    Tang Tang can''t stand it, so he curls up in his seat with his arms and leans against the seat, intending to squint for a rest.


    However, even if Tang Tang has been used to high-intensity work in the past, this time things for her, also really let her tired enough, this Mi then sleep in the past.


    It was not until the train was about to reach its destination and slowed down that she was awakened by the shaking.


    At this time, Chen Xin has woken up, and the blanket that covered him has also covered Tang Tang.


    "Xiao Chen, are you awake? Where are we? " Tang Tang rubbed his stiff face because he was asleep, stood up from his seat, put the blanket away and put it on the seat.


    Chen Xin shook his head, looked out of the window and then replied, "it''s dark outside. I don''t know where I''ve been, but I think I''m going to my destination."


    "Yes? That should be waiting for the train in front to get off. I asked the staff before. There is only a small railway station here, so it may be slow to get off. " Tang Tang remembers the information he asked the staff before and explains it to Chen Xin.


    Chen Xin also definitely nodded: "it should be almost the same. This time, more than 100000 people will be transferred. It''s not so simple to deal with."


    "Yes! It''s a very hard job just to resettle these people. I don''t know if the municipal government is ready to resettle them. " Tang Tang couldn''t help worrying about it.


    After all, there are more than 100000 people in a city, so it is not easy to settle them well before the disaster.


    "Don''t worry, these people will be resettled in the Dome City under construction. There are enough places for them." Chen Xin is not too worried about this. After all, he proposed the resettlement site, and he knows something about the situation over there: "although it is designed to accommodate 50000 people, now in this situation, more than 100000 people will not be able to accommodate, or they will be very crowded."

 Chapter 654

    The construction site of Dome City is now in chaos.


    The original construction has been suspended, and the whole dome interior has been temporarily cleaned up after the emergency stop of construction. Now a large number of people have been arranged to be resettled.


    Fortunately, most of the overall construction of the dome has been completed, and staying inside the dome can still play a role in preventing cold and keeping warm. In addition, the municipal government also brought the materials for resettlement when organizing the evacuation, so the tent was quickly set up and most of the people were resettled.


    Obviously, the resettlement of more than 100000 people will not be done well in a short time and a half. Even when Chen Xin and Chen Xin get off the train and come here, the resettlement work is still going on.


    Chen Xin didn''t intervene in these matters. The municipal government was free to plan in this respect, but he did.


    However, after arriving at the Dome City, Chen Xin quickly found the mayor and asked him to summon the relevant responsible personnel and the person in charge of the construction team on the construction site to hold a meeting.


    "As we all know, it is impossible for us to recover the city in a short time, so these 100000 people have to be resettled here first." When everyone came, Chen Xin took the lead in speaking and informed others of the current situation.


    "Academician Chen is right. Now we are faced with a very serious situation. Comrades should do their own work well. They should not let any people have no place to live or food. They must settle everyone at all costs." After Chen Xin finished his speech, the mayor also continued to speak, indicating the attitude of the municipal government and expressing his determination: "even if our own comrades want to go out to climb the ice and lie in the snow, we can''t let the people freeze and starve!"


    Although this sounds like a bit of formality, it''s still necessary to emphasize the keynote of the meeting on such an occasion.


    Therefore, Chen Xin did not oppose the mayor''s speech. After he finished speaking, he patiently listened to the speeches of several other leaders, and then asked about the current situation.


    Although he should not be in charge of these matters, in some ways, he, the academician of the scientific research center, is actually the one who has the right to overview and co-ordinate all the meetings in this room.


    Therefore, no one expressed any objection to Chen Xin''s inquiry about the current situation. Instead, they reported to him one by one.


    "At present, in terms of the construction progress, the main construction of the dome has been completed, the construction of some functional buildings in the city has also completed the foundation part, and the supporting planting shed and heating energy tower have only completed the foundation construction, which is the general situation." First of all, the person in charge of the construction team was reported. He didn''t give a detailed explanation, but gave a general explanation to let everyone know the current construction progress.


    After hearing this, Chen Xin nodded slightly, pondered for a while, and then said, "don''t rush to finish the construction in the city now. Take out the workers and go to cover the energy tower and the planting shed first, so that these two parts can work.


    The other is the railway station. Before, only your construction team used it. The small railway station has no problem. Now it must be expanded, at least to ensure the stability of the city''s heating and food supply. "


    "I know. I''ll send someone to implement it later, but there may be a shortage of people and some assistance may be needed." The person in charge of the construction team nodded, knowing that these were all intended adjustments, and did not say anything against them.


    After Chen Xin and the person in charge of the construction team finished speaking, he also turned his eyes to the mayor: "can the municipal government allocate manpower here?"


    "At present, it may not be possible. The people are basically still in the process of resettlement. For a while and a half, they may not be able to pull out people." The mayor looks embarrassed. It''s not that he shirks, but that he really can''t help it.


    Chen Xin was able to understand his difficulties, but still said to the mayor, "I can only give you two days. After two days, I want to see the resettled people and the transferred workers."


    "This..." the mayor hesitated for a while, discussed with other responsible personnel around him, and then gave a positive reply to Chen Xin.


    After solving this problem, Chen Xin also asked the mayor, "is there any difficulty in resettling the people at present? Is there any problem that needs to be solved? "


    "There''s no big problem in a short period of time. When we made plans for the tents and other materials for resettlement, we had to prepare them in advance. At present, except that so many people have to be resettled at once, the comrades at the bottom may not be able to get busy, everything is still under control." The mayor did not complain to Chen Xin, nor did he deliberately exaggerate. His answer was practical and realistic.


    Listening to the mayor''s reply, Chen Xin pondered a little. He didn''t say much. He just nodded and said, "we all know the current situation, so I hope you can work together to overcome the difficulties."


    This can only be regarded as a scene, but it''s appropriate to say that in the present situation.


    However, Chen Xin is not just saying beautiful things. After that, he also said to the person in charge of the construction team: "before, the dome city was designed to accommodate 50000 people, so there were a lot of ecological facilities, and the layout of the city was not very crowded, leaving a lot of living space.


    Now we need to accommodate more than 100000 people, and many places need to be adjusted. Later, I will contact the design institute and ask them to modify the drawings. At that time, the construction will need your cooperation. "


    "Academician, please rest assured that we will not delay! Any work given to us must be completed on time with good quality and quantity! " The person in charge of the construction team made a promise to Chen Xin.


    Chen Xin nodded his head with satisfaction, which was quite reassuring.


    After that, he also asked other people if there was anything that needed to be coordinated or coordinated by the superior department. After some handling, it was a matter of straightening out the myriad tasks of the people.


    After dealing with these issues, Chen Xin said to the public, "I know that temporary relocation and resettlement will have a huge impact on all people, and the resettlement work is also very arduous. However, we still have an important problem at present, that is, the shortage of materials. It''s definitely impossible to rely on the state to import materials. We have to find a way to solve the problem ourselves."


    "Well, what''s your plan, academician Chen?" When the mayor heard Chen Xin say so, he also felt that this matter really needed to be dealt with, so he looked at Chen Xin.


    "I plan to organize a team to go back to the city after the current situation stabilizes and try to collect the materials left in the city." Chen Xin expressed his thoughts and plans: "aliens will not need those human materials. There are still military forces in the urban area. It is feasible to organize people to collect materials."

 Chapter 655

    Although the resettlement work of more than 100000 people is complicated, it is still going on in an orderly way with the efforts of the staff, and soon everyone has a place to live.


    Although the so-called residence is only a tent and may be shared by several families, it is a place where people can temporarily live, so that all the people who have temporarily evacuated to the dome can finally settle down.


    After the people settled down, the work of the staff was not reduced, but increased.


    After all, after more than 100000 people have been resettled, the subsequent needs of eating, drinking and Lhasa''s life are still a very heavy work.


    And no more than in the original city, all kinds of things have to be planned and arranged, so that the staff of all departments are busy.


    In fact, even Chen Xin himself is also busy during this period of time. He has no rest time, and all kinds of things that need to be dealt with by him are piled in front of him.


    He needs to go to the design institute and the higher authorities for the planning and design modification of the dome city. He also needs to coordinate the conflict between the follow-up construction of the Dome City and the resettlement of the people. He also needs to come forward to discuss with the military to organize people to go back to the urban area to collect materials


    Although the original staff of the municipal government have disposed of a lot of work, there are still a lot of work to be handled by Chen Xin himself.


    After all, he is the person with the highest authority in Dome City at this time. Even the mayor needs to find someone to coordinate and discuss many things, but Chen Xin can make decisions here.


    As a result, a lot of things must be decided by him before they can be settled.


    Just like the planning and design modification of the Dome City, it is obvious that more than 100000 people will stay in the Dome City before the original city is recovered.


    But is the residence of more than 100000 people in the Dome City permanent or temporary? If the urban planning is revised, is it temporary or semi permanent or permanent?


    Different choices require completely different changes in urban planning and design, but only Chen Xin, the person in charge of the Dome City project, can make decisions.


    After discussing this matter with the main leaders of the municipal government, Chen Xin decided to modify the original design on the premise of semi permanent residence.


    After all, the dome city was originally designed to accommodate only 50000 people, taking into account both ecological and residential functions, while trying to restore the original blue star ecological environment.


    Now more than 100000 people are crammed in, which is not enough for the original planning. The places originally reserved as ecological areas are now full of tents, and there are people stranded here everywhere.


    This kind of situation is not serious in a short time, and the people can tolerate it for a while.


    However, if more than 100000 people live in tents for a long time, the subsequent problems will be very troublesome, especially when some problems accumulate to a certain extent and break out, even the country will not want to bear such a price.


    Therefore, Chen Xin and the design institute must revise the design drawings of the dome city according to the decisions made by the municipal government and the possible changes in the future.


    What''s more, Chen Xin worries that although the alien creatures are blocked by the military''s defense line, it''s still uncertain whether all the alien creatures are blocked and whether human beings can completely eliminate them.


    Dome City originally had no defense capability. Now do you want to upgrade and change it?


    In addition, the military now takes the original city as the defense line, the lake area is the battlefield, and the dome city is not far away from the war area. Should it be considered as a logistics supply base?


    These are all issues that Chen Xin needs to consider. At the same time, he must make decisions and be responsible for his own decisions.


    This is also the reason why Chen Xin didn''t sleep well these days after he came to the dome city to revise a drawing.


    There are too many things to consider.


    Fortunately, in the end, these problems have been implemented, and the new drawings have been revised by the design institute.


    In addition to these, the construction of the dome city itself has not yet been completed. Now it is necessary to settle a large number of people at the same time, and the conflict between the two is a problem that needs to spend a lot of time and energy to reconcile.


    Fortunately, this matter can be handed over to the staff of the municipal government to appease the people, so that the construction can continue.


    The construction is continuing, the drawings have been revised by the Design Institute, and the people are appeased by the staff of the municipal government. Generally speaking, most of the work at this stage has been dealt with temporarily.


    But Chen Xin still has no time to spare, because he is thinking about how to organize people to go back to the city to collect the leftover materials, and how to use the 100000 people who are idle now.


    As we all know, people can''t be idle. When they are idle, they tend to think about things. When they are busy, they have no time to think about other things, which is more conducive to social stability.


    Chen Xin had given an account of these things at the previous meeting. After the staff had settled the people, they began to count the labor force and draw out those who were willing to participate in the labor and work.


    At present, the workers who are willing to participate in the labor at the initial stage have been divided into two groups, all of which have been assigned to the construction team for arrangement.


    Because they are not professional construction workers, their work is mainly manual labor such as moving bricks.


    On the whole, although the problem is not without it, the situation is still good, there is no big trouble, and everyone is basically willing to work, so that the situation in the dome city tends to be stable on the whole.


    With the support of these workers, the construction team also set aside some of its staff and organized two new construction teams to complete the construction of facilities around the city mentioned by Chen Xin at the meeting.


    Some countries have urgently allocated an energy tower for heating, because the infrastructure construction has been completed before, so only all the parts can be installed after they arrive, while the greenhouse needs to wait for the energy tower to be built to get heating, which is not available at present.


    However, the expansion of the railway station is very smooth. Two new platforms have been built, which effectively improves the throughput of the whole station.


    This also makes it possible for Chen Xin''s planned organization to go to the urban area to collect the materials left behind.


    After all, the city is still under the control of the military. Although there are wars and there is a certain danger in collecting materials, on the whole, this plan is not infeasible.

 Chapter 656

    "At present, most of the urban areas are still under our control, and the buildings are relatively intact. We also arranged soldiers to collect and transfer the materials left behind by various shelters and warehouses." In a temporary communication room, Chen Xin is talking with the military commander in the urban area, the general he met before, and listening to the other party''s introduction of the current situation in the urban area.


    "So we are now organizing a group of people to go back to the city to collect materials. Is this plan feasible?" Chen Xin inquired with the general that although he was very concerned about the materials left over from the urban area, Chen Xin did not say that he would exchange human lives for materials.


    If the general told him that the situation in the city was dangerous and it was not suitable to organize people to recycle materials, he would not insist on this plan.


    Although it is very important and meaningful to recycle the materials left over from the urban area, the premise is to ensure relative safety.


    If it''s the same as the survival film of doomsday, it costs a few lives to collect materials, then Chen Xin would not be willing to do such a thing.


    Fortunately, the current situation in the urban area is fairly good.


    According to the general''s report to him, most of the urban areas are still in the hands of the military. After the initial encounter, the alien creatures are also weak. They did not invade the urban areas on a large scale. Only in the area along the lake, some areas that are not well defended were abandoned by the military and became enemy occupied areas.


    In addition, the penetration of workers'' ants into the city is not serious. This is mainly due to the reinforced concrete. After all, although workers'' ants have good tunneling ability, they seem to have no acid corrosion ability and can not dig reinforced concrete for the time being.


    This has greatly improved the safety of the city, and the feasibility of material collection in Chen Xin''s plan has also increased.


    "If we want to collect materials, I think it is feasible. As long as we operate in relatively low-risk areas, the safety can be guaranteed." After listening to Chen Xin''s idea, the general considered it and agreed to Chen Xin''s plan.


    Although there is still war in the front, it is a great risk for the rear to organize people to carry out this kind of material recycling operation, but after the general and Chen Xin made an assessment together, they all felt that the risk was worth taking.


    On the one hand, the military is in control of the situation, and the safety of the personnel involved in the operation can be guaranteed. On the other hand, these materials are very important for the 100000 people who are temporarily placed in the dome city.


    After all, these 100000 people suddenly left the city and left in a hurry. Each of them only carried his most important personal belongings. In addition, he didn''t bring anything else.


    Even the staff of the municipal government took the transfer of personnel as the top priority at that time, and gave up a lot of materials, equipment and other inconvenient things.


    At that time, it was a real need to give up these things, but now that more than 100000 people have been resettled, it is also an indisputable fact that they are facing a shortage of materials.


    Although the country is already organizing transportation capacity to allocate materials, compared with transporting materials from other places to dome cities, it is the fastest way to directly go back to the urban area to collect those leftover materials.


    And so many things just give up, the loss is still great, Chen Xin how a little reluctant.


    Although it makes him look like a little bit of a petty man, nowadays, if he can save, he can save, otherwise life will be hard.


    As the old saying goes, if you are not in charge of your family, you don''t know that firewood and rice are expensive. Although Chen Xin used to be the head of the scientific research center, the housekeeper is Tang Tang Tang, the executive director. She handles all the problems. Chen Xin doesn''t need to worry about these things.


    But now, he is actually the highest person in charge of the dome city. He is asked to deal with all the problems, and all kinds of problems are put on him at once.


    In the face of material shortage, Chen Xin can directly report to his superiors for material support regardless of anything, but it is irresponsible to do so.


    Out of a sense of responsibility, Chen Xin decided to go to the city to collect the materials left behind.


    After discussing the specific plan of action with the general, Chen Xin hung up the call with the general and was ready to send a team back to the city to collect materials.


    This news was soon known to more than 100000 people in the dome city. Although some workers had been dispatched to participate in the construction of the Dome City before, it was totally different from the risk of going back to the city to collect materials.


    For a while, few people are willing to take the initiative to sign up.


    Because he may indeed need to risk his life, Chen Xin still adheres to the principle of voluntariness as far as possible after consulting with the leaders of the municipal government, and does not intend to force the people to participate in this operation.


    In addition to publicizing and persuading as much as possible so that everyone can take the initiative to sign up, the city government mainly arranges the police and the city government staff for this operation.


    It is the duty of the police to protect the people. In addition, the special police force of the listed police station itself has a considerable degree of firepower. It may not be able to deal with those alien creatures, but it is better than unarmed civilians.


    In the end, in addition to the special police team, Chen Xin brought along some people who voluntarily signed up and some staff members of the municipal government.


    For the sake of operational safety, Chen Xin personally led the team, driving the white dragon as a guard.


    Qin Lan also drives Zhu Luan. This time, she has not seen her for a long time and works with her former colleagues in the special police team. Mo Qingyan drives Lu Shu as their support.


    Zhu Luan''s handsome and beautiful appearance and powerful combat effectiveness are the envy of Qin Lan''s special police team colleagues. This kind of powerful equipment is more attractive to them than any peerless beauty.


    Ding Ning and Qin LAN through a good relationship, but also climbed to the cockpit of Zhu Luan to feel some, then pester Chen Xin, let him also give himself a whole.


    Of course, Chen Xin knows that Ding Ning is only joking, but he does have some ideas about the police Titan at this time, but the most important thing now is to collect materials, so this idea can only be temporarily suppressed, and does not affect Chen Xin''s attention.


    "It''s dangerous to go back to the city to collect materials this time. Although the military still controls the situation and the area we went to is relatively safe, the danger still exists, so everyone must obey the command and can''t act without permission!" Chen Xin stressed to all those involved in the action that he was very serious.


    This is the first time that he has organized such an action and is responsible for the lives of so many people, which makes him feel great pressure.

 Chapter 657

    The group took the train from the Dome City back to the city.


    What they arrived at is still the high-speed railway station, which has been taken over by the military after being repaired, as a channel for the military to receive materials and external contacts.


    Although the original railway station in the urban area is larger and more convenient, it is very close to the forefront of the military defense line because of its location, even less than two kilometers.


    Once the alien creatures attack, it is easy to spread to the railway station.


    The high-speed railway station is much safer than the high-speed railway station. If you want to reach the high-speed railway station from the lake area on the other side of the city, you have to go through the whole urban area. Now that the military has deployed layers of defense, this is by no means an easy thing to do.


    However, compared with more than a dozen tracks on 89 platforms in the urban railway station, the high-speed railway station has only three platforms and four tracks, which is much smaller. Therefore, the throughput of materials is much lower.


    For this reason, the military has not given up the use of urban railway stations, but has strengthened its defense and deployed an armored train to assist in defense.


    However, it has nothing to do with Chen Xin and others.


    When they got off the train at the high-speed railway station, they left the high-speed railway station with their own equipment and were met by people arranged by the military, and came to the scientific research center where they are now the headquarters and logistics base.


    Chen Xin was a little surprised at this situation, but felt that it was reasonable.


    The location of the research center is very good, and all aspects of the conditions are very perfect. There is even a military camp left behind by the special forces. Next to it is the only Titan training base in China. The research center itself has the ability to repair and produce Titan and other military equipment. As a headquarters and logistics base, there is no problem at all.


    The reason why Chen Xin was surprised was that he was surprised when he saw that the place where he was before had become what he is now.


    Because Chen Xin had contacted in advance, the military was ready for them to collect materials. It not only helped to prepare the vehicles, but also specially sent a company of soldiers to protect their safety.


    "The current situation in the urban area is fairly safe. We have sent someone to clean up the area you are going to, and there is no sign of infiltration, so it belongs to a relatively safe area." The officer sent by the military to deal with this matter unfolded a map in front of Chen Xin and others, which marked the security area designated by the military: "although it is a relatively safe area, it is still dangerous, so please pay attention to safety when you collect materials."


    "Don''t worry, we are all ready for this. Before we came here, we also emphasized that discipline will not come disorderly." Chen Xin assured the officer.


    The two sides discussed the details of the operation again, and then everyone got on the bus and drove to the city.


    Chen Xinye, together with Qin LAN and Mo Qingyan, drives Titan to protect the safety of the motorcade.


    Although the safety of Chen xinlai''s convoy is somewhat strange in a sense, as the driver of Bailong, he doesn''t feel too disobedient in doing so.


    "Ah Xin, do you think everything in our house is still there?" In the communication channel, Mo Qingyan suddenly asks Chen Xin a question.


    Hearing Mo Qingyan''s inquiry, Chen Xin was stunned for a moment, and then replied: "it should still be there. Since the scientific research center is regarded as the headquarters by the military, the refuge of our family should also be there. If the things inside are not moved, they should be in good condition."


    "When we go back later, shall we go back and get something? I left in such a hurry that a lot of things were left behind. When it comes to supplies, there are many things in our shelter, aren''t there? " Mo Qingyan offers.


    "Well, there''s no problem. When we get back, we''ll have a look and see what we can take." Chen Xin thought about it and agreed.


    In the past, when we evacuated, we did not have time to pack up because of time constraints. As a result, we left a lot of materials and other things here. Now that we have the opportunity to take them away, we can not waste them.


    Having settled the problem, Chen Xin and others followed the motorcade to the target area, where the original urban hospital was.


    One of the most important reasons for choosing the place to collect materials is to take away a large number of heavy medical equipment and medical materials left behind in the hospital.


    These things are very important to more than 100000 displaced people, even more important than other things.


    "The first team is responsible for searching the hospital, the second team goes to the warehouse to carry materials, and the third team cooperates with the comrades of the military for defense. Everyone should move faster, move more materials as much as possible, and pay attention to safety at the same time. If you find anything abnormal, report it to me immediately." Arriving at the hospital, Chen Xin gives orders to the people he brings.


    Everyone knew clearly the importance of the matter, so after a promise, each team started their work according to the division.


    The first team in charge of searching the hospital is all police. Although they are not special police like the third team, they are more vigilant and more effective than the ordinary city government staff of the second team, so they are arranged to search the hospital.


    Although the most important part of the hospital is the drugs and medical materials stored in the warehouse, the medical materials scattered in various departments are also a big head. What''s more, the medical equipment is also urgently needed in the dome city.


    Many of the equipment are even left behind before the disaster, and some imported medical instruments can''t be bought now, so they have to be moved back as much as possible anyway.


    It''s just that these medical equipment are obviously not so easy to carry. Some small pieces of medical equipment were quickly moved to the car, but some large-scale equipment are not so easy to carry.


    After all, some of the equipment is not only big and heavy, but also very expensive. It can''t be bumped. Even the disassembly must be careful, so that the person in charge of the transportation is very constrained.


    Even before he came, Chen Xin took this into consideration and specially asked several professionals from the hospital who were familiar with the disassembly and maintenance of various medical equipment, but the speed of carrying these medical equipment was still not fast.


    Fortunately, as soon as the military entered the city, it blocked the underground road for the sake of safety, eliminating the possibility of alien creatures invading the whole process from the underground road. At present, the surrounding environment is still safe and there is plenty of time to move slowly.

 Chapter 658

    While others are nervously carrying supplies, Chen Xinze, Qin LAN and Mo Qingyan stop the three Titans at the entrance of the hospital together with others to guard.


    Although we all think that there will be no danger, but the safety issue can not be ignored, so all people keep vigilant, and no one relax or slack off.


    Even in the communication channel, everyone kept quiet as much as possible, and no one chatted.


    This undoubtedly makes the atmosphere a little dull, but the sound of gunfire can be heard vaguely in my ears, which still makes everyone understand that they are in war now, even in the rear, they can still feel the breath of war.


    Chen Xin is obviously not used to this kind of atmosphere. After all, unlike Qin LAN, he was a special police officer or a sniper before, and has long been used to this kind of highly concentrated work.


    It''s just that Chen Xin can''t go away and take a nap. Especially before, he said that if there is any accident, he will report it to him as soon as possible. If someone else reports it, he will be sleeping, which will be really embarrassing and delay things.


    Therefore, Chen Xin can only bring up his spirit and focus as much as possible at this time.


    "Chen Xin, are you tired? Why don''t you have a rest and I''ll watch for you? " Xiaobailong didn''t know when he climbed out of the console. Looking at Chen Xin''s tired face, he suddenly said to him.


    Chen Xin was a little surprised. Although xiaobailong is an artificial intelligence, she is only a weak artificial intelligence. It is reasonable to say that it is impossible for her to care about herself.


    "White dragon, how can you suddenly care about me?" Chen Xin feels a little strange and asks xiaobailong why she has this idea.


    When she upgraded the white dragon, she didn''t upgrade the little white dragon''s program. It''s reasonable to say that although she can have simulated emotions, she can only carry out the established procedures, and can''t have such spontaneous care.


    "Before Qin LAN has specially asked me through Zhu Luan, let me care about you." Xiaobailong doesn''t lie to Chen Xin or hide anything. He tells him the answer directly.


    Chen Xin was relieved to hear Xiao Bailong say that. If someone had told Xiao Bailong, her behavior would not be strange.


    However, Chen Xin didn''t agree with xiaobailong. He just shook his head at her and said, "no, Bailong, just help me pay attention to the surrounding environment. Before, he upgraded the radar and increased the vibration detection. You should pay attention to the vibration of the surrounding environment."


    "I know! Leave it to me Xiaobailong nodded to Chen Xin seriously and jumped on his shoulder. With a serious face, xiaobailong began to stare at the radar screen in front of him.


    With xiaobailong, who can speak, Chen Xin feels much better even if she doesn''t chat with her. She is not as boring as before.


    In addition, xiaobailong can also help guard, which makes him continue to guard at the same time, but also began to think about some problems.


    For example, why did he encounter that alien creature at the beginning, what was the purpose of these alien creatures invading the blue star, and how their mother communicated with other offspring through the organ like the biological transmitter as a swarm structure. Is there any higher existence on the mother


    These questions are all questions that Chen Xin has raised since he encountered alien creatures.


    Just because of the influence of various things before, he didn''t have time to think about these problems.


    Now that he finally had a little leisure, he could not help but let his thoughts fly and began to think about these problems.


    At the beginning, Chen Xin thought that the reason why he was attacked by the fighting progenitor of alien creatures was that the fighting progenitor was investigating.


    If we regard these alien creatures not as beasts, but as a group with high intelligence, many of their behaviors and practices can be well explained.


    Only in this way, while solving the doubts, it also makes the risk of these alien creatures soar.


    After all, the gap between a group of beasts and a group of higher intelligent creatures is quite large.


    It''s like a group of lions on the grassland. Although individuals know that lions can easily kill humans, lions will only occupy their own territory and then hunt for food to ensure their own survival. They will not ask for more and will not take the initiative to attack humans.


    But conversely, what if it''s a group of humans?


    Even the primitive tribes on the African grassland will want to eat better, get more things, expand their territory and fight with other tribes.


    Between the needs of higher intelligent creatures and those of lower intelligent beasts, the latter only needs to be fed, while the former has more desires and needs.


    If it''s just a group of wild animals, with the military''s current strength along the Dongting Lake, these wild animals can be easily exterminated, even if the military is relatively passive at present.


    No matter how cunning a fox is, it can''t fight a hunter.


    But if this is a group of advanced intelligent creatures, it will be much more difficult to eliminate them.


    That is to say, the intelligence of offspring may not be high, that is, the intelligence of animals like cats and dogs, but individuals like the mother who need to command at least one ethnic group will undoubtedly have higher intelligence.


    This point has been proved in the process of dissecting the maternal samples obtained before. With such a big brain, even if these alien creatures have no civilization, their thinking is still very primitive, which has been regarded as intelligent individuals.


    They are already entitled to ideas beyond survival.


    No matter what the idea is, such a group structure similar to that of insects is enough to make the lower children realize the will of the mother at the cost of their lives.


    Even if the mother''s idea will be destroyed with the whole group, the son will still carry out its will.


    What''s more, no matter whether extraterrestrial creatures are advanced intelligent creatures or not, their existence is bound to consume resources. Now the resources on the blue star are undoubtedly extremely limited, and it is impossible for human beings and extraterrestrial creatures to coexist peacefully.


    Between the two, it is necessary to separate a life and death, because only those who survive can obtain enough survival resources in today''s harsh environment to maintain their own survival.


    "It''s not that humans are exterminating alien creatures, but that two species are fighting for survival." Chen Xin couldn''t help muttering, which aroused little white dragon''s concern.

 Chapter 659

    There was no accident in the material recycling work of the hospital.


    Although this is a war zone, very close to the front battlefield, until Chen Xin and others completed the collection and transportation of materials, there was no encounter with alien creatures as originally expected.


    Chen Xin is very relieved. Although he is ready to encounter alien creatures and fight, if he can avoid fighting, no one really wants to fight.


    After all, war kills people.


    Even if today''s science and technology is advanced, the front line is to fight with alien creatures who only rely on flesh and blood, and the military has used a large number of modern weapons to reduce casualties, it does not mean that there are no casualties.


    In fact, even if Chen Xin and others don''t come to the hospital to collect materials, the military also plans to use this place.


    Of course, the military''s use does not mean that it will be converted into a field hospital.


    Although it''s not impossible, it''s still too close to the battlefield ahead, and the closure of the underground road is not completely safe.


    If alien creatures break through here, the wounded will not have much time to transfer.


    Therefore, the military''s plan is to move the medical equipment here to a safer place, and build a field hospital with these medical materials to treat the wounded.


    However, after Chen Xin sent the news that there was a need to collect the materials left over from the city, the military gave up the materials here in a big way. Chen Xin was the first to use them to meet the needs of more than 100000 people who had been transferred.


    For this reason, Chen Xin did not empty all the hospital''s supplies. He just moved some urgently needed medical supplies and equipment from the other side of the Dome City, leaving a lot of things for the military.


    At least a few operating rooms in the hospital have been emptied by Chen Xin, who left two for the military.


    For the military, what they mainly need is the treatment of trauma. After all, what they are vulnerable to on the battlefield is skin and flesh injuries, but other diseases are rare.


    The same is true for other medical supplies. Chen Xin left most of the medical supplies used to treat common injuries on the battlefield, and only took a small proportion. The rest are mainly medical supplies used to treat other diseases, which are not needed by the military.


    With these medical supplies, Chen Xin and others returned to the scientific research center.


    Chen Xin originally intended to let everyone have a rest and transport these materials to the high-speed railway station to load on the train. He also took advantage of this free time to go home and take all the materials he could take away from home.


    However, after Chen Xin returned to the scientific research center with his team, the general in charge of commanding the city''s operations found Chen Xin.


    "Academician Chen, if we want to restore Titan''s production capacity in the scientific research center, can we do it now?" The general didn''t know how to be polite to Chen Xin. As soon as he came up, he asked why he wanted to find Chen Xin.


    Chen Xin was stunned to hear the general say this, but he nodded his head and replied: "it''s very simple. We didn''t move Titan''s production equipment when we evacuated before. As long as there are enough technicians and raw materials, Titan''s production can be resumed at any time here, but I don''t really recommend it."


    After listening to Chen Xin''s reply, the general said that he did not recommend resuming Titan production in the scientific research center. He was not angry or had any other indication. Instead, he nodded his head with understanding.


    After thinking about it for a while, he continued to ask Chen Xin, "if you put Titan''s production on the other side of the Dome City, how long will it take you to resume production?"


    "Is it a bad situation? Does the military need Titans on the battlefield? " Chen Xin is a little strange. It is reasonable to say that the general should not have such a big demand for Titans.


    Titan naturally has an absolute advantage in the fight against alien creatures. This large-scale combat robot has moderate size, strong power and fierce firepower. It is very suitable to deal with the alien creatures encountered in the street battle in the urban environment.


    Even tanks and armored vehicles are not as easy to use as Titans in this urban environment. After all, tanks and armored vehicles are still lacking in flexibility. They can''t easily cope with all kinds of terrain in the urban environment as Titans.


    But judging from the current situation of the city''s defense line, the military has stabilized the situation ahead, is relying on the complex environment of the city to effectively resist the invasion of alien creatures, and has caused a lot of effective damage to them.


    However, from the time Titans were developed by Chen Xin to the time when Chen Xin sent the last batch of self disciplined Titans to the front line before the outbreak of the war, the military has at least obtained more than 200 Titans from the scientific research center.


    Although some of them are test models or improved civilian versions that were sent to the southwest disaster area for testing, the military has at least one combat force composed of more than 50 military Titans and 20 self-discipline Titans on the battlefield of this city. It is reasonable to say that there is no lack of Titan combat power.


    Chen Xin was surprised by the general''s eagerness to resume Titan production. However, he thought about it and replied, "if we transport the equipment here and guarantee enough raw materials, I can resume Titan production in three days."


    "What about the output?" The general seemed more excited and concerned.


    Chen Xin estimated for a while, thought about it and said, "a week, 20 sets, with sufficient raw materials."


    Of course, this output is not the real output of Titan production line in the scientific research center. Although we have mastered Titan production technology, the production time of one Titan has been reduced to one week, the Titan production line in the scientific research center can start five at the same time.


    The production line of parts is a little redundant, which can produce Titan and repair parts at the same time.


    That is, five Titans can be built in a week, plus parts that can assemble two titans.


    However, the previous research center was an experimental production, and the output was not the focus. It was more about mastering Titan''s production technology and improving Titan''s design.


    As long as the Titan can be built in the research center, it can be adjusted and repaired in time.


    Now, if the military has this demand, Chen Xin can also upgrade the production equipment and increase the output, which is not difficult for him.


    The general was relieved when he heard Chen Xin say this. Then he said to Chen Xin, "there are more than 20 self-discipline Titans supported by academician Chen and Titans in Titan training base in this city. With other troops, it''s really no problem to stabilize the front line, but the defense lines in other areas are not as stable as ours."

 Chapter 660

    As Chen Xin knows, the war situation in this city is in a relatively stable state, and the military has also stabilized its defense line, blocking alien creatures out of the city.


    However, the city is not the only battlefield in this war, and the direction of alien attack is not the only one.


    Along the coast of Dongting Lake, I don''t know when such a large number of alien creatures have been bred. It''s a strategy of comprehensive attack and flowering on all sides. It can be said that the whole Dongting Lake is surrounded by war zones.


    As one of the largest freshwater lakes in China, Dongting Lake has an area of more than 2000 square kilometers before the disaster, and the perimeter of the lake basin is more than 800 kilometers. It spans many counties and cities between Hunan and Hubei provinces, which can be said to be a very broad area.


    Since ancient times, there has been a saying that "three rivers and five lakes are in front of the city". Along the whole Dongting Lake, the city only occupies a corner of the East Dongting Lake.


    Relying on the advantages of Chen Xin''s scientific research center, the city has a large number of Titans into the battlefield, which can stabilize the war situation. However, other fronts along the Dongting Lake are not so easy.


    It has to be said that the physical quality of these alien creatures is really terrible. The chitin skeleton that can only be effectively punctured by heavy machine guns provides them with quite strong defense, which also adds great trouble for the soldiers on the battlefield to eliminate them.


    Although the military has deployed troops equipped with exoskeletons and heavy machine guns to the front line as far as possible, alien creatures are not human beings. They do not have the concept of focusing on attack, nor do they have the idea of occupying cities.


    It''s all about launching an attack on the whole line, where the outstanding part is played, where the main attack direction is played.


    And the huge number and powerful reproductive capacity of alien creatures are enough to support them to adopt such tactics.


    In fact, this is also the most difficult place for insects to resist. The vast sea of insects can not be resisted only by the defense line built by flesh and blood.


    Even though these alien creatures are not insects, their attack methods are the same as those of the swarm.


    Under such circumstances, the military can only pull up a line of defense with no gap along the whole Dongting Lake, nearly 1000 kilometers long, and then guard against it.


    Although relying on modern armored clusters, air force strike force, missiles, artillery and other technical equipment, the military has been able to stabilize the defense line as a whole, and has not allowed alien creatures to break through the defense line, the defense in other areas is not as abundant as that in the city.


    Now the cities along the Dongting Lake have been basically abandoned, and the population has been moved to the rear for resettlement just like this city. The city itself has become a part of the defense line to resist the invasion of alien creatures.


    But where there is a city, it can also build a defense line with the help of the city, while where there is no city, it must be as hard as before to shake with alien creatures in the wilderness.


    Although most of the surrounding areas of Dongting Lake are hilly areas, when the snow depth reaches more than 10 meters, the undulation of the terrain has been flattened a lot, which is almost a state of no danger.


    The military can only arrange defense lines as much as possible and suppress them with heavy firepower.


    And this kind of fighting method is undoubtedly extremely unfavorable for human beings. After all, people need rest and equipment will be damaged, but there is an endless stream of alien creatures, tireless and no need to rest.


    This kind of strategy, which is close to using the inferior sub body as a consumable like a bullet, puts a lot of pressure on the military.


    With Titan''s outstanding performance, the city has played a role in blocking alien creatures, which undoubtedly makes commanders on other fronts particularly envious when reporting the war situation.


    Naturally, he asked the general in charge of the city how to get more information about Titan.


    As a matter of fact, the entire theater command received reports about more Titans, which almost buried the headquarters.


    It''s not that we can''t fight without Titans, but with Titans, who wants to fight with those alien creatures with the flesh and blood of their soldiers?


    Especially when it is difficult to fight against the combat sub body even if equipped with exoskeleton armor, the military urgently needs a kind of equipment that can stabilize the front in the battlefield.


    Originally this kind of work should be tank, but in the face of flexible and a large number of alien creatures, the tank is not very good.


    The battle front in the wild can still rely on the mobility of tanks and alien creatures, but in cities, buildings affect the line of sight and roads restrict mobility. Tanks can not really play a good role in front of these alien creatures.


    Although the sharp teeth and claws of alien biological combat progeny have nothing to do with the tank''s armor, once they encounter the progeny carrying vesicles like a hermit crab, the high temperature corrosive liquid wrapped in those vesicles can still corrode the tank''s armor and kill the tank''s passengers.


    Although the military has sent a large number of land and air missions equipped with armed helicopters to support the battlefield, they are still at a disadvantage.


    After learning about the situation from the general, Chen Xin could not help feeling a little heavy and regretted that he had not considered expanding Titan''s production capacity before.


    Now if he has a factory that can produce Titans on a large scale, how can he make the front line so passive? Why should the soldiers rely on their flesh and blood to shake those powerful alien creatures?


    But regret is useless. Now the key is to solve the problem and come up with a way to make up for it.


    Fortunately, this is not difficult for Chen Xin.


    "In that case, general, please help to dismantle the equipment on this side of the scientific research center and transport it to the Dome City, where I will resume Titan production as soon as possible." At this time, Chen Xin could only say this to the general. At the same time, Chen Xin added: "in addition, I suggest that more Titan production factories be built in safe places in the rear. If the existing military factories have the conditions, they can also temporarily transform the production line to produce Titan.


    As for the technical problems in this respect, I will start to solve them when I go back. Anyway, I will provide the soldiers on the front with the equipment they need in the shortest time. "


    "With academician Chen, I can rest assured." When the general heard Chen Xin''s promise, he was relieved.


    With more Titans, the battle line will be more stable, and at the same time, more soldiers will not need to fight for alien creatures with flesh and blood.


    When it comes to equipment, Chen Xin suddenly remembers another thing he got back: "speaking of the mobile base I got back from Lucia? Where are they now deployed? "

 Chapter 661

    Because Titan''s production line is not easy to dismantle, Chen Xin and Chen Xin finally returned to the dome city with the materials collected from the hospital.


    On the whole, this material collection operation was very successful. It not only obtained the materials urgently needed in the Dome City, but also gave Chen Xin the latest information about the whole battlefield.


    Although the result of this operation is very satisfactory, the information about the whole battlefield obtained from the general is not optimistic.


    Although we have a lot of trust in the military and believe that the children''s soldiers will protect the people, it is an indisputable fact that the war situation is unfavourable.


    If Chen Xin is just an ordinary person, maybe he is not so worried now. Anyway, he believes in the country and the army, lives a good life at ease, and does what he can to support the country.


    But now he is not an ordinary citizen.


    At this time, Chen Xin can and must do more to change the unfavorable situation on the battlefield.


    As for what can be done to change the war situation, Chen Xin naturally has his own set of ideas. When he talked with the general before, he also exchanged ideas with the other party. While Chen Xin had more ideas, he also formed a more systematic idea.


    Of course, the plan itself lacks the necessary conditions for its implementation. Chen Xin does not intend to waste too much effort on it.


    At present, what Chen Xin needs to pay attention to is the urgent problems to be solved on the battlefield.


    Chen Xin knew from the beginning that the individual combat effectiveness of soldiers could not fight against alien creatures, but the biggest difference between human beings and wild animals is that besides human beings can use tools, there is a more important point, that is, unity and cooperation.


    It doesn''t matter that the combat effectiveness of individual soldiers is less than that of alien creatures. It only depends on the number of people who can kill them.


    It''s just that the number of alien creatures on the battlefield is vast. Relying on the worm sea tactics, the number of them far exceeds the forces that the military can mobilize at this stage.


    In addition, the logistics supplement capabilities of the two sides are also very different. It takes only a period of time for alien creatures to hatch a large number of new Progenies and send them to the battlefield, but human beings can''t.


    A qualified soldier only needs three months from joining the army to being able to go to the battlefield. Even if he can skillfully operate weapons under the wartime system, it will take him three months to effectively play his combat effectiveness on the battlefield.


    This undoubtedly puts human beings in a disadvantageous position.


    At this time, if you want to win the war, you can only use the advantage of equipment to increase the human''s killing of alien creatures, so that a soldier can kill at least 10 or 100 alien creatures on the battlefield. Only in this way can the war situation be effectively reversed.


    At present, exoskeletons and heavy machine guns equipped by the military are competent for this job, but it is difficult to say that they can form an advantage in the battlefield.


    That''s why the general asked Chen Xinwen to resume Titan production. At present, the military really needs armored units that can play the role of tanks in the battlefield and are as flexible as ordinary soldiers.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Back in the Dome City, Chen Xin asked people to deal with the materials brought back, and then directly found the person in charge of the construction team.


    "Give you 48 hours, can you build a steel frame factory for me?" Without any nonsense or politeness, Chen Xin directly asked the other party this question.


    "This... Steel frame factory building? If it''s just the frame of the house, 48 hours should be OK. " The person in charge of the construction team didn''t understand what Chen Xin meant, but after a little thought, he gave an uncertain answer.


    It takes 48 hours to build a steel frame factory. Although the factory structure built with colored steel tiles is really simple and easy to build, the 48 hour time limit still makes the person in charge of the construction team not very sure.


    But Chen Xin didn''t give him any bargaining room at this time. Instead, he asked him seriously, "48 hours, you can only advance, you can''t exceed, can you do it?"


    "This Looking at Chen Xin''s serious appearance, the person in charge hesitated for a moment, but nodded his head seriously and said, "I can do it."


    "If you can do it, you can immediately send out a construction team to build a steel frame factory of standard size. As for other things, you can follow up and build the factory for me first." At this time, Chen Xin''s style seems a little barbaric.


    But when he thought about the situation on the battlefield, he didn''t have the heart to spend more time. Everything seemed urgent.


    "What is the purpose of this plant? Are there any special construction requirements? " The person in charge of the construction team heard that Chen Xin asked him to build a factory. Although he didn''t know what Chen Xin meant, he instinctively asked some key questions.


    Chen Xin shook his head and said to the person in charge, "the factory is used to place the Titan production line, but you only need to be responsible for building the standard steel frame factory I want. I will deal with other problems. The battlefield in front is in urgent need of more Titans. If we can build the production line one day earlier and produce Titans, we can make the soldiers in the front pay less sacrifice, So I can only give you 48 hours. "


    The person in charge was very surprised at Chen Xin''s attitude, but when he heard that it was for front-line service, he immediately changed his attitude and seriously assured Chen Xin: "guarantee to complete the task!"


    With that, he turned around to call in his hands and began to carry out the construction task of the steel frame workshop.


    On Chen Xin''s side, he found the person in charge of the municipal government, informed them of the incident, and asked all of them to provide 100% support for the construction and production of Titan factory.


    As for Chen Xin''s order, everyone understands the importance of things, and no one really dares to paint any tricks on such things, or neglects his duty.


    After all, they are all government workers in the period of disaster. They pay more attention to efficiency and ability. Those who cheat and cheat have been eliminated from the government at the beginning.


    And thinking that this is to serve and contribute to the front line, everyone is actually very happy and willing.


    To be able to provide more support for the front line means that the front line is closer to the victory of the war, and the victory of the war also means that we can take back the abandoned cities and return to our homes.


    Although this may still be a distant thing, with such a belief, we can undoubtedly make everyone more active.


    Therefore, when the staff mobilized the whole Dome City, it was under the guidance of such belief that the whole Dome City burst out with great enthusiasm.

 Chapter 662

    The enthusiasm of the mobilized people is amazing.


    Many people spontaneously provided help for construction and material transportation, which also greatly accelerated the progress of construction.


    Within 48 hours, the steel frame workshop has been built in the factory area originally designated in the dome city.


    At the same time, after Chen Xin sent someone over, the military cooperated with those technicians to dismantle Titan''s production equipment, packed and transported them to the Dome City, and now they are in the process of intense installation and debugging.


    In addition, the railway station previously emphasized by Chen Xin has also laid two temporary railway tracks, through which materials mobilized from other places are continuously transported to the dome city.


    Although Titan''s production was carried out in the scientific research center before, in fact, not all parts were produced in the scientific research center.


    Chen Xin had considered Titan''s mass production before, so he distributed some parts to factories in other places for production in the form of orders.


    It''s just that the demand has not been large before, and each factory is just trying to carry out small batch production, familiar with the production process and master the production technology and process.


    But now that Titan is going to be produced on a large scale, the parts produced by these factories naturally need to be expanded.


    Fortunately, since the disaster, almost all industrial production has been regulated and allocated by the state. After Chen Xin reported the demand, the state soon arranged all the factories to expand production, coordinated all the resource allocation, and completed the transportation arrangement.


    As a result, within 48 hours after Chen Xin started to build the Titan factory, the factory building had been completed, the Titan production line dismantled from the urban scientific research center had arrived, the temporary railway tracks at the railway station had been laid, and the main raw materials and the first batch of spare parts were in place.


    By 72 hours, the factory equipment had been debugged, all kinds of raw materials needed for production had been ready, and the factory could start production.


    Of course, this speed is very fast, even faster than Chen Xin expected.


    In three days, not only the factory has been built, but also the equipment has been installed and debugged, and the whole production line can be put into use. This is really a miracle.


    Even Chen Xin was surprised by the construction progress. Even though he had expected the factory to be available at least in three days, Chen Xin was shocked when everything was really done and much earlier than he expected.


    But now is not the time to be shocked and dejected. Everyone''s efforts should seize the time to use it and produce Titans earlier to support the battlefield.


    Naturally, Chen Xin would not waste such precious time. After inspecting the factory and confirming that the factory is ready for use, he upgraded the system of the whole Titan factory, added new production lines for it, increased the output of the whole factory, and improved the production equipment and production efficiency.


    After upgrading the Titan factory, Chen Xin asked the workers and technicians to start the production of Titan.


    When Chen Xin was upgrading, he paid special attention to the part of the production process, and did not change the original Titan production process. He was still the production process he had mastered before, but only increased more production lines and improved the mechanical efficiency in the production process.


    Even so, one week after Chen Xin promised the general, 22 new Titans could go to the battlefield even though they didn''t have spray paint.


    When the factory entered full speed operation and kept producing Titans, Chen Xin was not idle.


    However, he did not participate in the production of Titan, but is trying to restore the operation of the research center as much as possible.


    After such a long time, the personnel and most of the equipment of the whole scientific research center have been transported to the Dome City, and are gradually returning to operation.


    Although there is no good experimental conditions in the original research center, we are still trying our best to restore the previous research.


    Especially for biological research, after arriving at the Dome City, the researchers set up a very simple biological laboratory and began to dissect and analyze the alien biological samples obtained from the battlefield.


    Strive to be able to analyze the characteristics and weaknesses of these alien creatures as soon as possible, in order to provide help for the soldiers who are fighting bravely in the front.


    In this kind of thing, although Chen Xin can''t help them in research, he can help them upgrade the conditions of the laboratory so that they can do better research.


    In addition to the biological research, the Armament Research Room of the former research center also moved to the research center. Although they left a considerable number of technicians to help repair Titan in the research center, some researchers came to Dome City.


    They are not idle, but constantly collect the use of various equipment on the battlefield, and then improve the equipment according to these conditions.


    On this point, all of them are better than Chen Xin.


    After all, ordinary people need to go through all kinds of complicated processes to improve their equipment, and Chen Xin only needs to know where to change and how far to change, so that he can directly solve all problems with a flash of green light.


    However, although Chen Xin can easily replace the work of scientific researchers in Armament Research, his main energy and time are still on Titan.


    Titan is really easy to use, but the current general model of Titan still exposes many problems in the battlefield.


    This is not to say that the previous universal Titans were flawed in design, but that they were not designed for the battlefield of fighting alien creatures.


    For example, the reactive armor on the general Titan''s outer armor is very effective in dealing with human armed forces. Even the direct attack of the tank''s main gun can also play a very good defensive role.


    But the inert explosives used in reactive armor are of no use to the claws of alien creatures.


    Moreover, the main armor made of metal and multi-layer composite materials is as difficult to resist the corrosion of the liquid when facing the high temperature corrosion vesicles thrown by alien creatures as the tank armor.


    After all, no one will design a tank or Titan considering that they will one day face the highly corrosive liquid that can bathe the whole Titan or tank.


    So far, the main damage of Titan on the battlefield is the corrosion of the outer armor, which leads to the internal structure damage.


    Therefore, it is imperative to improve Titan''s outer armor.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 663

    In order to resist the high temperature corrosion vesicles of alien creatures, upgrading the outer armor material is the most direct way.


    When it comes to corrosion-resistant materials, Chen Xin first thought of ceramics and ceramic armor.


    Corrosion resistance of ceramics is a common sense that many people know.


    Before Chen Xin became an Internet writer, he once worked in the chemical industry. It''s very normal to deal with all kinds of corrosive things in this industry.


    Among them, ceramic, plastic, and other corrosion-resistant materials made of parts or lining, is the most direct way to deal with metal materials in the process of use by a variety of chemical corrosion.


    The corrosion resistance of plastics may have overturned many people''s cognition, but in fact, there are such plastics, which are even widely used in the chemical industry.


    But this plastic is obviously not suitable for armor.


    After all, corrosion-resistant plastics are corrosion-resistant, and their strength and hardness are not high enough. Although they can not be pierced with a knife, they are far from being able to be used as armor.


    As for whether the strength of corrosion-resistant plastics can be increased to the hardness of tank armor, it is certainly possible, but the cost and time investment of R & D are not worthwhile, and can not meet the needs of the current battlefield.


    At this time, it is not to be as perfect as possible in the laboratory, but to take out as much as possible what can be used to meet the needs of the battlefield. As for the follow-up improvement, it can be done slowly.


    That''s why when we look at the military equipment in World War II, the early models are all messy and full of experimental things, while the equipment produced in the later period obviously has more optimized design and adapts to the changes of the battlefield.


    So instead of trying to improve the performance of plastics, it''s better to think of a more practical way.


    In fact, the armor of modern tanks is no longer composed of single material. The composite armor used by modern tanks is to stack multiple layers of materials with different properties to obtain the performance of multiple materials. To achieve a thin layer of armor is equivalent to the effect of heavy armor in the past.


    Therefore, Chen Xin wants to improve the tank and Titan''s outer armor, using the form of composite armor is the most simple and effective method.


    All he has to do is develop a new type of composite armor.


    But it is not so easy.


    In addition to plastics, corrosion-resistant materials also include ceramics, and ceramic composite armor has been used in the military field for a long time.


    But on the battlefield, even the tanks equipped with ceramic composite armor are still difficult to resist the high temperature corrosion vesicles of alien creatures.


    To a large extent, the reason is that the ceramic composite armor is designed to resist armor piercing projectiles rather than corrosion.


    The firing principle of the ceramic layer is different. With the thickness of the ceramic layer itself, after the high hardness alloy steel on the surface of the armor is corroded, the ceramic layer filled with glass fiber reinforced resin by ceramic balls in the middle can not resist the erosion of high temperature corrosive liquid, so that the bottom layer of high toughness alloy steel will be eroded together.


    Therefore, in order to resist the attack of corrosive vesicles from alien organisms, the corrosive liquid must be isolated in the outermost layer.


    "The outer layer is coated with anti-corrosion plastic, the middle layer is supported by high hardness ceramic interlayer, and the bottom layer is still made of high toughness alloy steel. Do you think this design can resist the attack of corrosion vesicles from alien organisms?" In the temporary laboratory, while drawing a diagram on the whiteboard, Chen Xin asked other researchers in the laboratory.


    Several researchers frowned and listened to Chen Xin''s explanation, but they shook their heads.


    "It''s a good idea, but even if the hardness of plastics is higher, it''s hard to match the performance of steel. And even if the performance can meet the requirements, the production cost will be very high in this case." A researcher is a little bit cold water, but he is obviously thinking from the perspective of reality.


    At this time, another researcher also chimed in and said: "the key is that even if we develop new armor, we have to replace all the tanks currently equipped by the military. In this case, the investment is too large, and even if the country agrees to this plan, it will take a lot of time to replace all tanks with new armor."


    "It''s easy to say that it''s a big deal to use armor plate to attach armor. Although the effect is poor, it can still play a defensive role. Now the key is how to design a new type of armor." Another researcher also joined in the discussion and put forward his opinion: "academician, in the final analysis, your design is to create a corrosion isolation layer on the surface of the existing armor to isolate the corrosion of the corrosion vesicles thrown by alien creatures. In this case, we will directly coat a special protective coating on the surface of the existing tank armor, Can it have the same effect? "


    "Protective coating? "Coating?" As soon as Chen Xin listened to the researcher''s words, he immediately understood what he meant.


    This is more practical than changing new armor. At the same time, both the cost and investment are much smaller, and it can meet the needs of the battlefield faster.


    Moreover, it is easier to develop a new type of coating to paint and coat tanks than to develop a new type of armor to replace tanks.


    "In that case, our R & D direction will be to make protective coatings!" Chen Xin also quickly adjusted his thinking and determined a new R & D direction. However, he stressed: "even if we are developing new protective coatings, the development of new protective armor can not be delayed. We should develop a new type of material or armor that can resist alien biological attacks, which can be used as a technical reserve for the next generation of Titans."


    There is nothing wrong with Chen Xin''s words. For a long time, Yanguo''s military industry''s research and development idea is to research and develop a generation, reserve a generation, and use a generation.


    New coatings can be applied to the battlefield immediately, while new armor can be used as a technical reserve for the next generation of equipment.


    However, this idea is undoubtedly based on the fact that this war will last for a long time. After all, only alien creatures will attack with corrosive liquid.


    The war between normal human beings will still focus on piercing rather than corroding armor.


    Therefore, both anti-corrosion coatings and anti-corrosion armor are only used to deal with alien creatures. If alien creatures can be eliminated in a short time, these things will not be useful.


    "Academician, do you think this war will last for a long time?" One researcher asked his own question.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 664

    Will the war last a long time? Chen Xin didn''t know this, but he felt that at least he should be prepared for a long-term war.


    In addition, the development of corrosion-resistant armor, even if the armor is developed, the war is over, and the armor can not be used, it can still be used as a technical reserve, not a waste.


    What''s more, Chen Xin, who consciously has system support, doesn''t think that his development of a corrosion-resistant armor needs to be delayed until the end of the war.


    With the task assigned, these researchers under Chen Xinji didn''t waste any time. They soon started the research and development of anti-corrosion coatings and anti-corrosion armor.


    Chen Xin himself is also involved in the design of the new model Titan.


    At this time, the whole Dome City has been running with high efficiency, and all the work has been carried out in an orderly way. Although there are still many things that Chen Xin needs to deal with, after Chen Xin entrusts most of the work to Tang Tang Tang, he can put most of his energy on the design of new Titan.


    The large-scale application and actual combat test of the general-purpose Titan in the battlefield have exposed a lot of problems as well.


    First of all, just like the iron cross zoo, although it is indeed advanced and easy to use, the maintenance of Titan is still a very troublesome thing.


    So far, only Titan''s preparation room and Titan''s pilot training base left by the original scientific research center can provide complete Titan''s maintenance and preparation services in the whole theater. In other areas, only temporary maintenance points can be set up to do some simple maintenance of replenishing ammunition and replacing consumables.


    However, this level of maintenance obviously can not guarantee the use of Titans on the battlefield.


    It''s very common to run out of ammunition in the battlefield against alien creatures. After all, when the swarms of alien creatures come towards you, the only thing you can do is either turn around and run, or hold the trigger and send all the bullets out of the gun.


    But in addition to replenishing ammunition, the biggest problem for Titan is the wear and tear of outer armor and joint parts.


    The wear and tear of joint parts was exposed when Chen Xin took Titan to the southwest for disaster relief and used them for the first time.


    He has tried to solve this problem, and he has indeed made a lot of improvements, replacing better quality parts, adjusting the structural form, and reducing wear as much as possible


    But these parts are easy to be damaged when they are used with high strength, although they are only relative to other parts.


    So in the previous improvement, Chen Xin and his researchers simply designed these parts to be replaceable, which can be disassembled cheaply. Once damaged to a certain extent, the whole parts can be directly disassembled and replaced with new ones.


    The old parts will not be thrown away. The worn parts will be removed for maintenance, and other parts that are still in good condition can be reused.


    Just replacing the damaged parts requires professional maintenance workers and professional sites.


    In the past, there were not many Titans in use, and they were not used with such high intensity to carry out combat missions. In addition, at that time, almost all Titans were concentrated in Titan training base and scientific research center. On the whole, the two maintenance points were completely adequate.


    But now the battle is fierce on the battlefield. Titan also has very heavy combat tasks every day. Most of the time, the pilots can rest, and after the maintenance of the body, they will continue to go on.


    This will maintain the number of Titans on the battlefield and ensure that there are enough Titans to fight on the battlefield, but the result is that the loss of Titans is much higher than that of normal use.


    The replacement parts consume a lot, while a large number of parts that can be recycled after replacement can only be sent to the training base and the servicing room of the scientific research center that has become the headquarters, which undoubtedly affects Titan''s maintenance efficiency.


    Therefore, Chen Xin plans to adopt a design that is more convenient for maintenance in the design of the new Titan, not only for the replacement of parts, but also for the establishment of simple maintenance points on the front line, so as to complete the maintenance of a Titan without making it too dependent on logistics.


    So far, though, Titan''s performance on the battlefield is not "too" logistics dependent.


    The most critical problem that really causes the lack of logistics maintenance is that Titan is a kind of new equipment in the stage of finalization, research and development, and trial. They do not have a large number of military equipment, and they do not have a large number of use. Therefore, they have not established a complete logistics support system.


    It is precisely because of all this that Titan has played an outstanding role in the battlefield, but at the same time, the logistics maintenance is very difficult.


    As a matter of fact, for modern war, it is no longer a matter of fighting for numbers, occupying space or relying on the victory of one battle to win the whole war.


    What really determines the victory of a modern war is logistics. It can even be said that from the Napoleonic era, the key to military victory has become the success of logistics support.


    This is reflected even in the battlefield with alien creatures.


    In fact, in terms of the combat power comparison between the two sides, although the human army is not superior in individual strength, the military power and various advanced weapons mastered by human beings are enough to beat the alien creatures.


    However, the speed of alien creatures replenishing progenies is far faster than that of human beings replenishing equipment consumption on the battlefield.


    Humans can spend a week to build a bomb and transport it to the battlefield, killing a bunch of alien creatures, but in this week''s time, alien creatures can hatch the bomb, kill more than twice the number of new offspring, and send them to the battlefield.


    This is the most intuitive comparison of logistics supply capability between human and alien creatures at this time.


    Therefore, for Chen Xin, the design of the new Titan must consider whether the logistics can keep up, and whether the current national production capacity can meet the needs of large-scale production.


    In addition, the key point is compatibility.


    The design of the new Titan will take time. Although Chen Xin will soon come up with a suitable finalization plan, it will take time to arrange production, equip the front line and form combat effectiveness. Before that, it is undoubtedly necessary to mass produce the original general Titan.


    As a result, after the design of the new Titan, the military will be equipped with the original universal Titan.


    If there is a big difference between the two titans in terms of driving mode, parts used for maintenance and maintenance mode, it will inevitably lead to various problems in use.


    Although it''s not that it can''t be overcome, as a designer, we should avoid these problems.

 Chapter 665

    On the battlefield of the West Dongting Lake, with the roar of artillery fire, the soldiers on the battlefield are struggling to resist the attack of alien creatures and try their best to eliminate them.


    But the literal meaning is like the tide of alien creatures, wave after wave of offensive, still let the soldiers resist very difficult.


    The attack of alien creatures never stops. The soldiers can only stick to the defense line with their willpower and fight with these seemingly endless enemies.


    "Comrades, there will be bombing in three minutes. Seize the opportunity to hand over the battlefield!" An officer on the front line received a new order, looked at his watch and yelled at all the soldiers.


    After all, the soldiers are not made of iron. Even if they have the will of iron, the superior in charge of the command can''t make a troop stand on the battlefield all the time without repair.


    However, the alien creatures did not give them time to breathe and rest. The constant offensive made the soldiers even have no time to stop and drink.


    The only way to delay the attack of alien creatures on the battlefield is to use large-scale carpet bombing to temporarily block the attack of alien creatures, and then let the soldiers take advantage of this short gap to make the reinforcements go up, withdraw the exhausted soldiers and replace them in the rear to repair.


    This is also thanks to the great role played by Titan troops in the battlefield of East Dongting Lake, which delayed the attack of alien creatures and brought a lot of effective killing. The situation of the battlefield of East Dongting Lake is better than that of West Dongting Lake, and the air force can use more force to bomb West Dongting Lake.


    Otherwise, the entire Dongting lake coast needs to use such means to replace and repair the troops. In any case, the rotation of combat troops can not be guaranteed.


    As for artillery troops, although they have been providing artillery support for the battlefield, and they have the ability to launch a large-scale artillery attack to block the attack of alien creatures, the effect of artillery attack is not as effective as carpet bombing.


    Moreover, artillery forces should also ensure continuous artillery attack on the battlefield and assist the front-line combat forces to effectively kill alien creatures.


    The officer in charge of the front-line command looked at the watch on his wrist and felt that the second hand walked very slowly in these three minutes. But finally, after the longest pointer turned three times on the dial, the bombs from the sky arrived as scheduled and quickly created a sea of fire in the front of the battlefield.


    Explosion, fire, flying shrapnel, relying on the steel and fire falling from the sky, a brief blank appeared on the battlefield, and the continuous offensive of alien creatures also stopped at this moment.


    As the sea of fire spread towards the rear of the alien biological offensive, the reinforcements who came to replace the front quickly entered the battlefield and exchanged positions with their exhausted comrades, so that they could be replaced to rest.


    The officer in charge of the command stares at the front line nervously, while letting his soldiers quickly complete the handover of the battlefield, he is on guard against alien creatures taking the opportunity to sneak attack.


    Although it seems too cautious to be so wary of a group of alien creatures, it has not happened before.


    When the air force carpet bombed the alien creatures, a unit also took over the battlefield and took turns to have a rest. However, a unit of the alien creatures raided their positions by tunneling, causing the unit and the unit that came to take over to be unprepared.


    Although the soldiers fought bravely and a land and air regiment came to support in time, they succeeded in repelling the attack of alien creatures, but both troops suffered heavy casualties, and even the land and air regiment that came to support lost two helicopters.


    Obviously, it was a premeditated sneak attack, that is, taking advantage of the opportunity that human beings would take advantage of the gap created by bombing to carry out rotation to sneak attack on the positions.


    Naturally, after that sneak attack, although the handover and replacement on the battlefield was still the gap created by air force bombing, the vigilance of both the replaced troops and the troops coming to replace was greatly improved. Even if they were about to be replaced, they were still guarding the whole position.


    Fortunately, there was no problem in this battlefield handover. After greeting the newly reinforced force commander, the officer and his soldiers successfully withdrew from the front line.


    After returning to the rear temporary camp and arranging the rest and ammunition supply for the soldiers, the officers got a little leisure and relaxed.


    He took out a crumpled package of cigarettes from his pocket, drew out one and lit it. The officer took a long breath.


    Cigarettes have become extremely luxurious now. After all, the country''s greenhouses have to be used to grow food. There is no spare place to grow tobacco. Even if there is one, it can only be a small amount of special supply.


    Even if he wants to get a pack of cigarettes as the commander of an army, it''s not easy. It''s hard for him to get a pack of cigarettes from others before.


    Twenty cigarettes he smokes are very rare. Only when he comes down from the battlefield can he light one.


    Now there are only three unlit cigarettes left in the box, which means that he has been rotated at least seventeen times on the battlefield.


    "I don''t know when this battle will be fought!" Smoking, the officer could not help but complain.


    Although soldiers should not have such weariness of war, the offensive of alien creatures has never stopped until now.


    When they first entered the battlefield, the alien creatures were what they were, they are what they are now, how many they were then, and how many they still have now, just like they did nothing after a month''s battle.


    This situation is very demoralizing for both grassroots soldiers and front-line commanders like him, and it also puts great pressure on those who are facing the alien biological warfare peak.


    Although he has been sticking to the defense line and never wavered in his belief, after a month of fierce fighting, anyone will think in his heart, when will this battle be fought.


    Although the eight year war of resistance against Japan lasted for a long time, there was hope. The enemy killed one and lost one. It was not as good as it is now. After fighting for half a month, the enemy did not know how many had been wiped out, but there were never fewer enemies in sight.


    Although the officers also know that they have actually eliminated a large number of enemies, the replenishment of alien creatures is too fast, just like there is an assembly line in the rear producing new progenies, which makes the alien creatures on the battlefield have no sense of reducing at all.


    Just as the officer crushed out the butt of his cigarette and regained his spirits, ready to have a good sleep to recover his energy and rejoin the battlefield, he suddenly felt a strong vibration coming from his feet and a loud noise coming from the outside.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 666

    When the officer came out of the barracks following the noise, he saw a huge steel structure.


    Eight broad tracks run over the snow beside the camp, making the feet feel a violent vibration. The huge chassis and the steel structure more than 200 meters long and more than ten stories high on the chassis are like the aircraft carrier on the shore, giving people a great sense of pressure.


    Especially when there are helicopters taking off and landing on this huge steel structure, the officers really feel that the Navy, which is equivalent to canceling the establishment, has finally brought the warships frozen in the sea to shore.


    Because the huge steel structure in front of us is just like an aircraft carrier.


    But this is not a real aircraft carrier, just a mobile base.


    "The state has finally sent this thing!" Next to the officer, another officer suddenly spoke in praise.


    The officer looked sideways and found that it was an acquaintance. Then he asked, "Lao Wang, do you know this thing? Talk about it


    When the officer asked, the other officers who took turns to rest also noticed Lao Wang''s words, and they all focused on it.


    "This is a mobile base. Last year, the country got something from Siberia. I''ve heard other people talk about it." Lao Wang''s troops are elite and have access to more information.


    Although what he said was that he had heard of others, at that time, the mobile base was actually parked in the station where their troops were, and they were responsible for protecting it.


    However, this kind of information belongs to confidentiality, which obviously cannot be said casually.


    Listening to what Lao Wang said, all the other officers showed a look of sudden realization. Only the officer who asked questions before continued to ask Lao Wang: "what''s the use of this thing? It looks like an aircraft carrier. Isn''t it just for taking off and landing helicopters? "


    "I don''t know. I''ve also heard that this thing can be used for battlefield support, and it should have combat effectiveness, right?" Lao Wang said ambiguously. Although he knew something, he didn''t say anything to avoid leaking the secret.


    Several officers saw that they couldn''t get any more information, and after looking at the mobile base for a while, they scattered one after another.


    Basically, everyone has either just withdrawn from the battlefield or is ready to go to the battlefield. No one has extra leisure to watch the excitement here. It''s serious to seize the time to rest and prepare.


    The same is true for officers who have just retired from the battlefield, but he can''t help but hope for mobile bases.


    If the country only now transfers it to the battlefield, it obviously thinks that the arrival of mobile base can provide support for the battlefield.


    For their commanders and soldiers who are fighting on the front line, no matter how much support they have, more support can relieve their pressure on the front line.


    Therefore, for the arrival of mobile base, officers still hold expectations, hoping to see the performance of mobile base in the battlefield.


    However, the mobile base did not let the officer wait and be disappointed. When he took turns to fight on the battlefield again, the officer saw the use of the mobile base.


    With the assistance of air reconnaissance, the mobile base locates the situation behind the alien creatures, and then several missiles are launched from the deck of the mobile base to attack the rear of the alien creatures.


    Missiles are not used to directly attack alien creatures. Although they can reduce the pressure on the front line, they can also have a good effect. To achieve such an effect, it is good to use artillery. There is no need to use missiles.


    The real target of the missile is the burrow of the alien creatures discovered by the air reconnaissance.


    Even if extraterrestrial creatures are capable of digging, it''s not easy to dig holes like this to transport troops to the battlefield.


    Once it is blown down, it will undoubtedly have an impact on the replenishment of alien forces. Even if it can be excavated again quickly, it can still have an effective impact on the offensive of alien creatures.


    At the same time, several obviously specially modified transport helicopters with several huge figures also swam on the battlefield. They put their Titans into the battlefield where they need support, so that these guys can help the soldiers on the front, stabilize the front and destroy the enemy.


    In fact, the logistics of using missiles to attack alien creatures is only a task after the mobile base arrives at the front line. When such a mobile base appears in the battlefield of West Dongting Lake, the most critical task is to send the newly manufactured Titans to the front line, and provide rear service support for the Titans, so as to ensure that they can play a maximum role in the front line.


    As for the helicopters carrying Titans, they are also specially modified. After removing the bottom of the cabin, they are directly transformed into several fixed frames to fix the Titan. At the same time, they are equipped with recoil parachutes, so that the Titan can be directly airdropped to the front line, so that the Titan can be more efficiently sent to places in need.


    After the Titan completes its combat mission, these helicopters can recover the Titan and transport it to the next place where it is needed, or send it back to the mobile base to replenish ammunition and equipment.


    These Titans were the first ones produced by Titan factory in Dome City. After they were produced, they were sent by Chen Xin for the first time.


    According to Chen Xin''s prior plan, another mobile base that had never been seen before was transformed into a Titan support ship by him, and the helicopter carried by him was also transformed into a tactical support platform that can deliver several Titans to the battlefield at any time.


    The effect of mobile base and Titan on the battlefield did not disappoint the officers who had great expectations of it. Relying on the high mobility provided by helicopters, which was like the fire brigade, Titans effectively helped to stabilize the front.


    This makes the soldiers in front feel less pressure, at the same time, it also makes the general in charge of commanding the battlefield of West Dongting Lake feel relieved.


    The battle of West Dongting Lake has no advantage over that of East Dongting Lake. He has been fighting a tough battle.


    In the past, because one could not effectively contain the attack of alien creatures, even if the armored forces were organized to try to counterattack, the effect was very few, and some armored forces were lost, which made the general very difficult and depressed all the time.


    Now he has an effective mobile power in his hand, which gives the general time and spare power to adjust the front and arrange more effective defense.


    After seeing the role of the mobile base carrying Titan in the battlefield, the military leaders finally made up their mind to start building and deploying more mobile bases.

 Chapter 667

    At this stage of the war with alien creatures, Yanguo has already used all its strength, and the whole country has changed from the previous post disaster reconstruction and survival construction to the war mode.


    Fortunately, all aspects of the country were under state control before, but now the adjustment of the state model has not had the same dramatic impact as the change from the peaceful era to the war model.


    But even so, it has had a great impact on the whole country and brought considerable losses to the national economy and people''s livelihood.


    After all, everything in Yanguo before was to serve the people''s livelihood. Now the whole country''s strategic direction will be changed, and everything will be affected.


    The allocation of materials, the transformation of production and construction, the allocation of human resources


    Problems affect all people''s lives.


    This undoubtedly makes everyone look forward to the early end of the war.


    But how long will the war last? This question is not only being asked by the common people, but also by the senior management.


    To this question, everyone hopes that the answer is tomorrow, that the war will end tomorrow, and that everything will return to its original state. This is undoubtedly the answer that everyone hopes to hear.


    Unfortunately, the war will last for quite a long time.


    Although it is said that the military has blocked the Bing Feng of alien creatures and blocked them in the Dongting Lake area, which has not spread the invasion of alien creatures, it does not mean that the war can end soon.


    For the military, it has exhausted all their strength to be able to stop alien creatures in the Dongting Lake area and prevent the invasion from spreading.


    At first glance, it may be inconceivable that such a big Yanguo has the world''s first army. Even if the disaster has caused a heavy blow to Yanguo, it is not enough to say that the military has only this strength, is it?


    But in fact, the situation is far worse than expected. The tide like offensive of alien creatures and the literal comprehensive attack along the Dongting Lake make the military have to take a comprehensive defense way, and deploy heavy troops to defend each section of the lake.


    This is equivalent to that every inch of land on the lakeshore of nearly 1000 kilometers around the whole Dongting Lake is equipped with enough defense to resist the attack of alien creatures.


    Such a defense line has never existed in the history of human war.


    This is because it is impossible for human beings to adopt such an offensive mode, and there is no such force to adopt such an offensive mode.


    So this involves a large number of military forces. After all, there are only so many standing armies in Yanguo. After removing the troops that can''t be mobilized casually, there are only so many troops that can be used.


    This can not help but make all people wonder, what do aliens grow up on?


    Even if the insect population can breed offspring and progenies on a large scale, produce them like an assembly line, and consume them like bullets, it will consume resources, right?


    How do they maintain such an exaggerated breeding speed and maintain the offensive?


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "What do aliens grow up on? Why do you care about this? " In the office, while having lunch, Chen Xin, who takes the opportunity to have a rest, can''t help but ask Mo Qingyan the question.


    Mo Qingyan is here to deliver food to Chen Xin. During this period, Chen Xin has been busy working in the office, even eating and living in the office, and has no time to go home.


    Worried about his health, Chen Xin''s parents made a meal every day and asked Mo Qingyan to bring it to him to supervise him to have a good meal.


    As for why Mo Qingyan is curious about this problem, the main reason is that she heard about the recent war situation from Chen Xin and couldn''t help feeling it.


    "People are very curious. Even insects have to eat? The insects in the game at least have a fungus blanket or something. It''s logistics, but the invading alien creature can''t see logistics at all. Even if it''s planted from the ground, it doesn''t grow so fast, does it Mo Qingyan looks at the photos on Chen Xin''s desk. They are the photos of Dongting Lake from the sky. The whole surface of the lake has been completely covered by alien creatures, which seems to be enough to frighten several people to death.


    After all, as Mo Qingyan said, even insects have to eat, so how do so many alien creatures breed?


    Even the factory assembly line production also needs raw materials. These alien creatures can''t be created out of thin air.


    In response, Chen Xin just shook his head and said, "when you cleared the alien nest, didn''t you go with me? Aliens are hatched in eggs, and their food... Should be obtained from the mother. "


    "The matrix? The big monster we saw at the time? " Of course, Mo Qingyan still remembers the super large matrix she saw last time, but it still puzzled her: "but does the matrix have to eat? Where does the initial energy come from? "


    "We don''t know yet. The biology lab is doing the analysis, but it''s speculated that they get energy from magma." These news are not confidential, so Chen Xin didn''t avoid telling Mo Qingyan something: "according to our conjecture, this kind of alien creature relies on its mother to absorb heat from magma, and then convert it into energy material in its mother body, that is, the high-temperature body fluid is transported to its daughter body and the embryo in its mother body.


    With this high-energy material, the embryo can hatch quickly, and the offspring can have enough energy to fight.


    According to the information we have obtained, this speculation should be no problem. Moreover, according to the information we have obtained, extraterrestrial creatures are also recycling the bodies of their offspring killed on the battlefield. Obviously, these biomass can be recycled. "


    "Eating bodies?" Mo Qingyan can clearly understand what this means.


    Chen Xin did not angry white her one eye, with chopsticks knock bowl: "I''m still eating!"


    "Sorry!" Mo Qingyan quickly apologizes to Chen Xin.


    However, both of them obviously didn''t mind this and quickly skipped the topic.


    "Ah Xin, when do you think the war will end? If the country uses a nuclear bomb, it should be able to kill all these alien creatures in an instant, right Mo Qingyan takes the photo taken by the reconnaissance plane and looks at the dense alien creatures on it. She asks Chen Xin.


    However, Chen Xin still shook his head and replied in a negative way: "not to mention whether the country is willing to use nuclear bombs on its own territory. Even if nuclear bombs are really used, it''s difficult to completely eliminate these alien creatures. At most, it''s just to wipe out those that appear on the surface of the lake. It won''t have a good killing effect on the matrix deep underground.


    As long as the mother is still there, these alien creatures will still be able to reproduce rapidly and soon return to their present scale. It is impossible for us to keep throwing nuclear bombs to destroy these alien creatures, right


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 668

    In fact, there are still some mistakes in Chen Xin''s judgment, because the high level did consider whether to use nuclear weapons.


    For high-level officials, maintaining the current front means that soldiers are killed every day and a lot of logistics supplies and ammunition are consumed, which brings heavy pressure on the army and the country itself.


    If we can use nuclear bombs to quickly clean up the alien creatures on the battlefield, the high level is willing to use nuclear weapons.


    After all, the whole area of Dongting Lake has been completely occupied by extraterrestrial creatures. In addition, even if there are no extraterrestrial creatures in the current environment, the whole lake area belongs to no man''s land, so the use of nuclear weapons will not cause too much impact.


    And now the nuclear weapons are no longer the kind of serious pollution model, relatively speaking, they are very clean. Even if they are really thrown away, the country can afford to use them.


    The main reason restricting the high-level use of nuclear weapons is whether it can play an effective role.


    As Chen Xin said, it is useless to kill the offspring of many alien creatures if we only clean up these alien creatures on the surface of the lake area and can''t deal a blow to the alien nest deep underground.


    So for the current high-level and military, what they need is not nuclear weapons, but weapons that can solve these alien creatures once and for all.


    To achieve this, we need to have a good understanding of alien creatures and their weaknesses.


    And that''s what biologists do.


    In fact, from the very beginning when Chen Xin killed the fighting offspring of the alien creature, biologists have been studying the alien creature.


    Especially since the beginning of the war, the state has mobilized a large number of experts and scholars to crack alien creatures and find their weaknesses as soon as possible.


    But how fast is it to study a new species? In particular, they don''t have living samples, and all of them are dead individuals. The progress of the research is also affected.


    However, although there are problems objectively, subjectively, these biologists still hope that they can immediately crack the secrets of these alien creatures and find their weaknesses.


    After all, the war has affected everyone in Yanguo. These biologists know that they are duty bound and become the key to the victory of the war.


    If we can find the weaknesses of alien creatures one day earlier, we can formulate new strategies and tactics for these alien creatures one day earlier, so that human beings can win the war one day earlier.


    But even if all biologists have done their best, and even take the initiative to work overtime, the research on the weaknesses of extraterrestrial organisms is still slow.


    This has led these biologists to make a seemingly inhuman request to obtain living samples.


    Although capturing prisoners on the battlefield is a part of war, from the beginning of war, there has been the activity of capturing prisoners.


    But in today''s battlefield, it''s not easy to capture the prisoners of alien creatures.


    Apart from that, when only Titan can confront the alien combat progeny in strength, ordinary soldiers want to subdue it, no less than ordinary people want to subdue a crazy elephant.


    It''s easy to say that there are narcotic drugs that can make alien creatures lose combat effectiveness, but so far, human beings have not found a way to subdue this alien creature other than directly killing it.


    At present, the military has sent out Titan teams to try to capture alien creatures, but they have gained little. Basically, all they can catch are the offspring who have been beaten to death or even lack arms and legs.


    And before they are sent to the research laboratory, these progenies usually end up on their own.


    If you want to capture the experimental samples that can be used for research, unless you can make these alien creatures completely incapacitated, but also save their lives, and prevent them from committing suicide, then it is possible to send them to the laboratory for research.


    And that''s too hard to do, even if the military has Titans.


    However, after hearing about it, Chen Xin thought about it and said that he had a way to have a try.


    As for Chen Xin''s idea that there is a way to capture living creatures, the biologists who are in charge of the research all have bright eyes. They are eager for Chen Xin to get some living alien creatures for them.


    However, the senior management and the military are not very willing to agree with Chen Xin''s approach.


    Because Chen Xin''s way is to send out his three specially installed Titans, and use their more powerful fighting power than ordinary Titans, as well as Chen Xin''s special transformation, to capture living samples of alien creatures.


    Capturing living samples of alien creatures to crack their weaknesses is indeed the key to the success or failure of this war.


    But this does not mean that the state is willing to use Chen Xin as an important scientist in exchange.


    However, Chen Xin made several applications and said that he was confident enough. Finally, the senior management agreed to his plan to let Chen Xin go to the theater to capture living samples of alien creatures.


    With the permission of the high level, Chen Xin quickly upgraded Bailong, zhuluan and Lushu, which not only strengthened their weapons, but also carried a set of equipment for capturing alien creatures for Lushu, which has the auxiliary ability in the three bodies.


    In order to ensure Chen Xin''s safety, the military specially mobilized a unit to coordinate around. At the same time, a Titan team was responsible for assisting Chen Xin to complete their task.


    It can be said that in order to capture the living samples of alien creatures, the high-level and the military have invested as much as possible.


    Chen Xin is not very worried about whether he can catch the living samples of alien creatures. What he is worried about is how to take the captured living samples back intact.


    Chen Xin was surprised by the fact that he committed suicide immediately after he was arrested. At the same time, he was more worried about whether these alien creatures really had the same thinking connection and higher nodes in command as the Zerg in science fiction.


    After all, in the history of mankind, the army that can decisively commit suicide after being captured, except for the army of a certain country who had a good life in World War II, the army of other countries is not so crazy, let alone animals and beasts.


    But now that he has decided to take action, Chen Xin can only hope that the capture equipment he installed on Lushu''s body can work well, so that he can successfully capture the living samples of alien creatures and subdue them.


    With such apprehension, Chen Xin, together with Zhu Luan, Lu Shu and the Titan team, drove the White Dragon into the "dangerous" area in the urban area where alien biological activities were confirmed.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 669

    While Chen Xin is driving the white dragon and taking the Titan team into the dangerous area to search for alien creatures, their actions are also discovered by alien creatures.


    In fact, as Chen Xin guessed, these alien creatures do have superior command nodes and thinking networks.


    However, the higher command node is not the parent in Chen Xin''s conjecture, but the existence that has not been seen so far.


    The mother does have high intelligence, and also has a certain command ability, which can be used as the command node of alien creatures.


    But this kind of command node is the same as the lower level officers on the front line. It is only the lower level command node of alien creatures, and its control range and number of offspring are very limited.


    In a sense, the existence of the matrix is just an extension of the superior command node, similar to a signal amplifier, which is used to transmit the command of the superior command node to the subordinate command node.


    There is one thing that Chen Xin and biologists have not misjudged, that is, these extraterrestrial creatures do communicate by using electromagnetic signals through organs similar to biological transmitters in their bodies.


    However, the lower level sub body only has the ability of communication, while the command nodes at all levels can forcibly control the lower level sub body through the electromagnetic signal, just like the game player manipulating the role in the computer, not only can he "see" and "hear" all the information received by the lower level sub body, but also can directly let the lower level sub body act according to their own orders.


    Whether it''s to let them charge at the risk of bombing and gunfire, or to commit suicide after being captured.


    Or they can be used as surveillance cameras to monitor the invaded area.


    For Chen Xin''s white dragon, the superior command node of the alien creature is "impressive". After all, the initial encounter was the collision between a controlled combat daughter and the white dragon.


    However, the emotions of alien creatures are quite different from those of human beings. Although they are "deeply impressed" with the white dragon, it does not mean that the superior command nodes of alien creatures have any special ideas or emotions about the white dragon.


    Just because of the impression of the white dragon and the cognition of the superior command node, these huge iron cans have amazing combat effectiveness and can easily kill the fighting offspring, which is much stronger than those small meat men.


    This makes the higher command nodes have a great "curiosity" about these tins. They want to know what''s going on with these tins, hoping to crack the powerful secrets of these tins, so as to enhance the fighting capacity of the ethnic groups.


    Therefore, when humans want to capture living samples of alien creatures, the superior command node of alien creatures is also preparing to capture Titan.


    The hunting ground chosen by both sides happened to be in this alien biological activity area marked as a dangerous area by human beings.


    On the ground, there are human Titan squadrons and armored forces that are searching, while on the ground, there are worker ants and a large number of combat ants that are digging, as well as special bubble ants specially prepared by higher command nodes to capture human Titans.


    The vesicles emitted by these vesicles are not high-temperature corrosive liquids, but liquids with strong viscosity that can quickly condense into colloids. Some of them are similar to the silk thread or mucus sprayed by spiders or other organisms for hunting. As long as the vesicles hit, they can catch prey.


    In fact, Chen Xin''s strategy is similar, except that in order to ensure that he can catch the living samples, and due to the limitation of materials, Chen Xin does not use mucus, but electric shock traps installed on Lushu.


    As long as it is aimed at the target to launch, it will open a conductive net made of high conductivity wire and high strength molecular material in the air, cover the target, and then send out a high-voltage electric shock in time, so as to achieve the effect of paralyzing the target.


    The reason why we choose electric shock instead of other ways to capture is that so far biologists have not found any other means to make alien creatures lose their ability to move.


    Anesthetics are not easy to use. Ordinary anesthetics can''t pierce the chitin exoskeleton of alien creatures. Moreover, the size of alien creatures also requires the use of anesthetics in a large dose before they can be subdued.


    With the activity of alien creatures, it is not a realistic thing to inject a large number of anesthetics into them after they are captured on the battlefield.


    With this, it''s better to directly corona the vehicle according to the alien biological injection of anesthetics.


    And in the previous war, it is not without testing, high voltage electric shock is still effective for alien creatures.


    It''s just that in the previous battle, we wanted to shock alien creatures. Some technical details were not solved. Although we successfully captured the living samples, we committed suicide before they were sent to the laboratory.


    This time, Chen Xin solved some technical problems in detail, making it possible to catch the net through high-voltage electric shock. This is his greatest reliance to promote this action.


    In fact, at this time, Chen Xin had already detected the existence of alien creatures in this area through the biological detection radar on the white dragon.


    This is also Chen Xin''s absorption of alien creatures to take the lead in attacking. He directly broke through the ground and gushed out from the ground. He surrounded them like a tide.


    In the face of alien creatures, the whole Titan team instantly set up a defensive formation, and set up the dense array defense system and 75mm short tube portable gun that Chen Xin specially installed for this team to fight against alien creatures.


    Chen Xin also raised the long-range weapon equipped with white dragon and began to shoot while looking for the opportunity to capture alien biological samples.


    Although the original capture action has become a confrontation, Chen Xin does not intend to waste this opportunity. He said to Mo Qingyan, "Qingyan, pay attention to seize the opportunity. I will try to create an opportunity for you. When you hear the signal I give you, you will launch the electric shock net carried by Lushu. Don''t be afraid. Alan will cover you."


    "I know, I know what to do!" Facing the surging alien creatures, Mo Qingyan is very nervous, but she still grasps the joystick and responds to Chen Xin loudly.

 Chapter 670

    Human beings, alien creatures, the two sides of the army launched a fierce battle.


    Human bullets, artillery, and alien bubbles and claws are intertwined and dancing on the battlefield, forming a picture that can not be drawn with the most heavy colors.


    Every minute, every second, there''s death spreading, from aliens to humans.


    Although the Titan team on the human side, the core of the battlefield, played a very strong fighting force at this time, almost completely pressing the alien creatures to fight, the armored forces responsible for supporting the battlefield on the periphery were under great pressure.


    In the face of such a situation, it is obvious that this planned raid can not be turned into a protracted war.


    Although the surprise attack has turned into an encounter, Chen Xin''s goal is very clear, that is, to capture living samples of alien creatures. Once this goal is achieved, they can retreat without having to confront with alien creatures.


    "No way! The situation must be opened up! " Chen Xin yelled in the communication channel that the situation in front of him was the last thing he wanted to see: "the Titan team will help the armored forces and block the main force of alien creatures'' attack! Alan, you cover me! Pay attention to the timing! I''ll give you a chance! "


    With that, Chen Xin said to the white dragon on the console: "white dragon, start the overclocking mode!"


    "Yes, Chen Xin!" Little white dragon answered loudly, and with her reply, the color of the light in the cockpit changed to blood red, and at the same time, red light overflowed from the outside of white dragon''s body.


    "Overclocking mode start, countdown 5 minutes!" Small white dragon a small face full of serious and nervous, loudly to Chen Xin.


    At the same time, a big red countdown appeared on the console, reminding Chen Xin to pay attention to the time.


    Chen Xin, who started the overclocking mode, didn''t waste time either. As soon as he pulled the joystick, the whole machine flew out close to the ground and rushed into the alien creatures.


    "Chen Xin!" Qin LAN and Mo Qingyan see Chen Xin suddenly rushed out, immediately issued a exclamation.


    Of course, they are worried about Chen Xin and want to rush up to help, but now it''s a battlefield. They can''t be so emotional.


    Qin LAN immediately calms down and releases the mechanical hound that has been following him all the time. She also controls Zhu Luan, opens all her weapons and shoots at the alien creatures around Chen Xin, providing cover for Chen Xin.


    Mo Qingyan in Lushu is still worried about Chen Xin, but she also controls Lushu and cooperates with Qin LAN to provide cover for Chen Xin.


    Although Lu Shu is not as powerful as Zhu Luan in long-range attack capability, it still has its own unique mode of operation. Several UAVs taking off from Lu Shu''s back swept the battlefield quickly with Chen Xin''s specially added electromagnetic weapons, and built a defense line around Chen Xin almost in an instant.


    In fact, with the power of three specially installed planes, it''s very easy to kill alien creatures. Even the white dragon, who has rushed into the enemy group, is just like a peerless general after turning on the overclocking mode, and is playing an unparalleled mowing in the enemy group.


    What really makes Chen Xin feel embarrassed is how to select one of these alien creatures as a target, separate it from the enemy group, and subdue it to be captured by Lushu.


    However, at this time, the Titan team, who was responsible for cooperating with them, did not stay in place. According to the instructions given by Chen Xin, they quickly walked through the ruins of the city, quickly cleaned up the surrounding alien creatures, together with the surrounding armored forces, curbed the attack of alien creatures, and cut off the lines of alien creatures.


    For a moment, the battlefield became a dolly like situation. The core of the situation was Chen Xinhe''s alien creatures. Outside the alien creatures, there were mechanical hounds, zhuluan and Lushu who were constantly wandering and hunting. Outside of them, there were Titan squadrons and armored forces. Outside of them, there were the waves of attacks from alien creatures.


    "Academician Chen! The attack of alien creatures is too fierce. We won''t last long! " The commander of the armored forces evaluated the battlefield situation at this time. Although he was strongly supported by the Titan team, his armored forces were still unable to withstand the attack of alien creatures on such a scale.


    "Call the air force! Give me three minutes! " Chen Xin yelled in the communication channel, asking the armored forces to hold on.


    At this time, around Chen Xin, all the alien creatures have been slaughtered by him, and after the subsequent offensive has been blocked, the number of alien creatures can not be replenished, and has been rapidly reduced, and will soon reach the level of carrying out the capture task.


    At this time, Chen Xin is not willing to give up, but also can not give up.


    The commander of the armored forces is not affectable at this time. As a soldier, even if he is ordered to be nailed to the battlefield and fight to the last soldier, he will only fight to the death and not retreat, instead of saying to the commander that he can''t hold on and ask to withdraw.


    Since we have been instructed to persist for another three minutes, we should persist for three minutes.


    What''s more, what he said won''t last long. It''s only relatively speaking. It''s not that he won''t last for just three minutes.


    While calling for air force support, the commander yelled to his soldiers, "comrades! Hit me hard


    For a moment, the firepower of the peripheral armored forces seemed to be much stronger, and even the alien creatures'' tide like offensive seemed to be frustrated for a moment, and the offensive slowed down.


    While the surrounding armored forces are fighting hard, Chen Xin''s countdown is less than two minutes away.


    White dragon''s overclocking mode can indeed bring extremely powerful combat effectiveness, and even can instantly kill a large number of alien creatures as if it were unparalleled. However, it also brings a great burden to the body and Chen Xin himself as a driver.


    Therefore, the overclocking mode can only last for five minutes. At the end of the five minutes, Bailong must go back for overhaul before it can use the overclocking mode again.


    Therefore, there is no such thing as insisting on perseverance. Chen Xin must complete the arrest in the five minute overclocking mode.


    Fortunately, with the cooperation of all parties, he has cleared the surrounding alien creatures, and will soon achieve his goal.


    "Attention, Qingyan!" Chen Xin shouts to Mo Qingyan and changes his attack mode. He starts a fighting daughter from the alien creatures around him and throws it at Mo Qingyan!


    Relying on the strength of the body in the overclocking mode, which is far stronger than that in the normal mode, Chen Xin throws the combat sub body up and flies straight to Mo Qingyan.


    Mo Qingyan didn''t waste this opportunity either. The electric shock capture net equipped on the back of Lu Shu was launched, which turned into a big net flashing electric light in the air, netting the thrown combat sub body.

 Chapter 671

    "Academician Chen! You''ve been fooling around with this operation! As a scientist, how can you drive Titan to the front by yourself A leader like person in front of Chen Xin angrily said to him dissatisfied.


    It''s not that this leader is dissatisfied with Chen Xin, but that, as he said, Chen Xin, as a scientist, should not rush to the front like a soldier.


    Originally, the senior management agreed that Chen Xin would send three special aircraft Titans to capture living alien creatures. It was expected that the armored forces would cooperate with the Titan team to raid the areas where alien creatures were active. After discovering the alien creatures, they would block most of them and only put a small part of them across the defense line. Then Chen Xin would take care of them and complete the capture.


    Finally, under the cover of the air force, all people leave the battlefield, and everything is done perfectly.


    But although the plan was good, no one thought that a surprise attack turned into an encounter, and the alien creatures sent out an unimaginable army to attack Chen Xin.


    The surrounding armored forces could not resist the attack of alien creatures, so they had to let the Titan team to support.


    According to the original plan, it is obvious that Chen Xin, an important scientist, will not be allowed to work hard directly. At this time, it can be judged that the action has lost the opportunity, so we should give up the task and retreat to avoid Chen Xin''s danger.


    But no one thought that as a scientist, Chen Xin would be so reckless. He overloaded his Titans and went up so recklessly.


    Although the result was good in the end, they successfully captured the living samples of alien creatures and completed the retreat under the cover of the air force. In addition to certain losses suffered by the armored forces, only the white dragon needed to be overhauled, with no other losses.


    However, Chen Xin''s behavior undoubtedly attracted the dissatisfaction of the senior management, which made them regret that they let Chen Xin go to the battlefield.


    This leader is undoubtedly the one who was sent to warn or preach to Chen Xin.


    Facing the leader''s preaching or rebuke, Chen Xin can only listen carefully at this time, with helpless expression on his face.


    After all, he still understood the bad words. The reason why the senior management sent people to preach to him was that he really took some risks this time.


    Although the white dragon''s combat power is amazing, it''s Zhao Zilong on Changbanpo after turning on the overclocking mode. It''s OK to kill seven in and seven out of the alien creatures, but it''s still too risky.


    After all, Chen Xin is an important scientist, not an ace pilot.


    He should stay in the laboratory and do research peacefully, instead of charging at the front like a big soldier.


    The general is responsible for directing the battle, and the soldiers are responsible for the attack, while the scientist should never do what the soldiers do, which is the greatest waste of his own value.


    It''s just the situation at that time. What Chen Xin did, though risky, was the most likely way to accomplish the task.


    The white dragon, which he specially upgraded before departure, has improved the performance of his landline, ensuring that the white dragon can still ensure his safety even when facing a large number of alien creatures, and effectively eliminate alien creatures at the same time.


    And that''s why he''s able to take such a risk.


    So for this operation, Chen Xin did not think it was dangerous, but he couldn''t bear the alien creatures. Suddenly, he didn''t know what to do. He launched a large-scale attack on them and almost let Chen Xin overturn.


    As a result, he really has no good reason to refute the leader''s preaching at the moment. He can only listen carefully and show an open-minded attitude.


    Fortunately, although Chen Xin''s adventure is dangerous, the gains are still worth it.


    Three combat progenies were captured as living samples.


    Although Chen Xin killed all the surviving individuals and even the valuable embryo samples at that time when he first encountered alien creatures and cleared the alien nest, now it is one time and another.


    In order to overcome the weaknesses of alien life, biologists need living samples.


    In fact, this is one of the reasons why Chen Xin wants to fight. After all, he gave the original order to kill all living samples, in order to eliminate the possible uncontrollable consequences caused by biological experiments.


    But now, the uncontrollable consequences do not need biological experiments as a prerequisite, it just jumped out.


    As a result, when humans want to study alien creatures, all they can use are the dead bodies after being killed, and there are no living samples to study.


    The three battle progenies Chen Xin captured this time are the first and only living samples that biologists have obtained.


    At this time, a large number of biologists are around the container holding the three fighting daughters, looking at the three fighting daughters in the container, full of the desire to study and explore.


    "All right, everybody!" After listening to the leader''s lecture, Chen Xin clapped his hands and attracted the eyes of the biologists around the container. Then he said, "ladies and gentlemen, these three biological samples are not easy to come by. Please use them sparingly. At the same time, we should study and analyze the biological habits of this alien creature as soon as possible and find out their weaknesses."


    "Academician Chen, don''t worry! We''re not going to waste your hard work A biologist smiles kindly at Chen Xinbao.


    Seeing the leader''s admonition to Chen Xin just now, he can understand how much the country has paid for the three living samples.


    Behind this price is not only the investment of the state, but also the heavy responsibility.


    Whether human beings can defeat the alien creatures, biologists'' research on these three living samples is very important.


    "I believe you will not disappoint the country and the people, so start the research as soon as possible. If there is anything I can do for you, just open your mouth, even if you want to catch some more living samples." Chen Xin, half joking, half serious, made a promise to biologists.


    "Living samples are not needed for the time being. If academician Chen is required to capture living samples every time you go to the battlefield in person, then we really dare not take this living sample any more." At this time, the biologist waved his hand. Chen Xin''s going out once caused so much trouble. If he wants to go out again, no one can stand it.


    However, although too many things have happened in this capture of living samples, these samples have been obtained safely. Relying on the special container provided by Chen Xin, these combat progenitors can stay in the container quietly, instead of making their own decisions directly like those previously captured.


    This immediately aroused biologists'' desire to study. Looking at this container, they asked Chen Xin, "academician Chen, does this container limit the communication between alien creatures and the outside world? Can this prevent them from committing suicide? "

 Chapter 672

    With the capture of precious living samples, the research on extraterrestrial organisms has undoubtedly been injected with new vitality, and the research has made great progress soon.


    Although the weakness of alien creatures has not been solved up to now, it also enables human beings to have a certain understanding of the habits of alien creatures.


    This is of great significance for human beings to deal with the attack of alien creatures and even the subsequent strategic counterattack.


    However, while biologists are seriously studying these precious living samples, people from the military find Chen Xin and ask him about the sudden outbreak of powerful combat power when he was driving the white dragon.


    "You say that? That''s the overclocking mode of the white dragon. It can be regarded as the secret weapon I added to the white dragon. By overloading, the output of the body can be increased to 300%, which can greatly enhance the combat power of the body in a short time. " Chen Xin did not hide the overload mode, but said it frankly.


    In fact, he also expected the military to pay attention to this matter. After all, the combat effectiveness shown by white dragon before is really amazing. If Titans can have such combat effectiveness, the plan of human counterattack against alien creatures can be put on the agenda.


    So the military naturally put forward such ideas and suggestions to Chen Xin, hoping that he can carry the same overload system on the general Titan that the military is now equipped with.


    However, in the face of the military''s request, Chen Mo shook his head and said: "Bailong can use overload mode because it is a special aircraft specially built by me. The performance of the aircraft itself is reserved because of the driver''s burden, and not all of it is released. Therefore, in overload mode, the combat power can be increased by three times.


    However, the general Titan itself is weaker than the white dragon in terms of body performance. Although it has certain potential to be tapped, the installation of overload mode will increase the body performance to about 150% ~ 170% at most, which will not be greatly improved. "


    On hearing this, the people of the military are not too disappointed. They also understand that the performance gap between the specially installed aircraft and GM''s mass-produced aircraft is not as amazing as that of Bailong. As long as the combat power can be effectively improved, even a little is good.


    So the people in the military are still full of hope to ask Chen Xin: "150% is also good! Academician Chen, can these Titans equipped by the army pretend this overload mode?


    You are also on the battlefield. You must know that in the battlefield, if you have more fighting power, the soldiers will have more chances to survive. Although GM Titan is not as powerful as your white dragon, overloading it at the critical moment can still play a great role. "


    If GM Titan is equipped with overload mode, it can really play the role of reversing the war situation or protecting the lives of soldiers on the battlefield at the critical moment.


    "It can be installed, but I want to remind you that even Bailong, considering the bearing capacity of the body and the driver, can only run for five minutes at most after starting the overload mode. Moreover, after overloading, it must enter the site for overhaul and replace the parts before using the overload mode again." Chen Xin explained to people in the military that although he didn''t think there was any problem with overloading ordinary Titans, he still had to make it clear: "if it''s a general Titan, it''s limited by the performance of the body itself and the material quality. Although they can use the overloading mode, it''s basically a one-time waste. If it''s a killer mace to turn the war around at a critical moment, It''s not impossible, but if you hope to make it a regular tactic, I suggest you change your mind. "


    Overloading can bring about a powerful explosion, but the body will be scrapped after it is used up, which is obviously not in line with the military''s ideas and requirements.


    Although it''s not impossible to say that, Titan is not a cheap mass production product. The cost of a Titan is almost more than three main battle tanks. If you use it once, it''s too wasteful. It''s really not in line with the military''s good tradition of thrift.


    So after a little hesitation, the military asked Chen Xin, "academician Chen, is there any way to make adjustments? Can we reduce the output increase after overload, extend the overload time or reduce the loss of overload to the body


    It''s a very simple solution. Since overloading does great damage to the body, can I reduce the damage by overloading a little? Or extend the overload time?


    As for this problem, Chen Xin nodded after thinking about it: "it can be, but it''s not of great significance. Instead of using ordinary general Titan to transform and install overload mode and turn mass production machines into consumables, it''s better to concentrate more resources and build an elite team with special installed machines to carry overload mode for these special installed machines and play a greater role in the battlefield."


    Chen Xin''s idea is no surprise. It''s just two different ways of thinking: strengthening the ordinary army and forming special forces.


    The military naturally wants both. Although the country''s overall resources are not as abundant as they were before the disaster, the post disaster reconstruction work in the past two years has been fairly good, and the production of various materials can still be supplied.


    However, in the past, because war is unlikely to break out in this environment, basically all the resources have been allocated to production and reconstruction for the construction of people''s livelihood.


    Now that the war has broken out, the country has also transformed from economic construction to war mode, and various resources have been allocated to military production. Now the military hopes to get the general Titan and elite special aircraft equipped with overload mode, which can still be achieved.


    Although titans are expensive, the military can afford one or two hundred general-purpose Titans and more than ten or twenty specially installed aircraft.


    So of course, they put forward two requirements for Chen Xin.


    Chen Xin didn''t have any opinions about this either, but after thinking about it, he replied, "GM Titan, I''m trying to develop a new model. Since you have made such a request, I can try to upgrade and improve the new model. In overload mode, there won''t be much improvement in combat power, but it won''t be scrapped after one use.


    As for the special installed aircraft, everyone has different habits and different requirements for the body. I need the driver to connect with me personally. "


    "Let''s go back and choose the driver!" The military got Chen Xin''s promise, and immediately felt a little excited.


    Chen Xin''s achievements with Bai Long, Zhu Luan and Lu Shu are really amazing. When he thinks that he can form such a Titan team with the same amazing fighting power, the military has more confidence in winning the war.


    After all, although the war can be won through bloodshed and sacrifice, who is not willing to use equipment instead of human life to consume and win?

 Chapter 673

    The mass production Titan with overload mode required by the military is not difficult for Chen Xin to complete. He just needs to make some modifications to the design drawing of the new Titan, adjust some parameters, and add overload mode to the new Titan.


    It may be difficult for others to complete this in a short time. After all, overload mode has a huge impact on the body itself, and the body has to make adjustments from structural design to material selection.


    Although it is modified on the existing drawings, the workload is no less than that of redesigning a new one, or even redesigning a new one.


    However, for Chen Xin, adding overload mode to the new Titan is just an upgrade to the drawing.


    Of course, in order to be on the safe side, Chen Xin also handed over the revised drawings to the research department for review, instead of directly taking them to production.


    Although it won''t be a big problem in terms of the result of the system upgrade, it''s still safe to let other people go over it again. Maybe there are some amazing people in your own hands. What can you do to make changes that make people shine?


    As for the promise of the military''s special installed aircraft, it''s much simpler. When the time comes, we''ll start mass production and upgrade them directly.


    In fact, if it wasn''t for the production of specially installed machines, he had to work together and upgrade the system to achieve it. With conventional production technology, even the original white dragon could not be copied. Chen Xin had already upgraded all Titans to the level of white dragon, and even pushed them on the battlefield.


    Although the cost of upgrading Titan with a special installed machine is very high, for Chen Xin now, he can still afford to pull hundreds of special installed machines.


    Unfortunately, not to mention hundreds of specially installed aircraft, hundreds of titans are just squeezing out toothpaste. It''s almost impossible to pull hundreds of specially installed aircraft in the battlefield.


    However, now that the military intends to form a small team composed of special installed aircraft, it can still play a positive role in the battlefield.


    Chen Xin is also very concerned about this. He used Bailong himself several times before. It can only be said that there is no way. After all, he is not a soldier. He is really so desperate that he is afraid.


    This is not to say that he has to drive the white dragon to the battlefield to show off anything, but that the white dragon, Zhu Luan and Lu Shu are all special installed planes made by him for fun and to verify the technology, which are very different from ordinary Titans in operation.


    In addition, Chen Xin didn''t want his own things to be used by others, so he didn''t let other drivers drive the three bodies.


    Now that the military has set up an elite team equipped with special aircraft, Chen Xin will no longer have to go to the front line. If there is any need to deploy high-end combat power, it can be entrusted to this elite team.


    Even if the effect is good, a second and a third elite team can be formed later.


    As for the resources needed to build the special installed machines of the elite team, this is actually a secondary consideration for Chen Xin. Although he has no way to mass produce the special installed machines with the system in hand, it doesn''t cost him much to build several special installed machines.


    It''s not that Chen Xin can''t do mass production and special installation. It''s that the investment in mass production and special installation is too large, and it needs to transform all aspects involved in the whole production process, which is basically equivalent to upgrading the entire national industrial system. This is neither a matter that can be finished in a moment or a half, nor the most critical thing at present.


    Throughout the war history of mankind, we can see that what the army really needs is reliable, durable, and easy to mass produce and maintain equipment. As for whether the equipment is advanced or not, it should be considered after meeting the above requirements.


    Advanced technology and equipment are certainly good, but if it is not conducive to maintenance, can not mass production, only small quantities of equipment, then this equipment can play a very limited role in the battlefield.


    This can be seen from the fact that AK47 is the most popular gun in the world.


    Although some people deliberately belittle the AK47, saying that the quality of the gun is not good. It was only when suvia invested a lot of resources in the AK47 that the gun became so classic, there is no denying that the AK47 is a very durable gun.


    Whether it''s desert, swamp, snow field or tropical rain forest, even if there is sand, mud, ice and snow in the barrel of the gun, it will not affect the use of AK47. Moreover, even those black uncles in Africa who have not attended school can make it by themselves, which is quite convenient for production and maintenance.


    This also created AK47''s international reputation and status, and became the weapon that killed the most human beings.


    From the example of AK47, we can see that before the emergence of technology gap, the most important thing of equipment was that it was easy to maintain, reliable and durable, and easy to mass produce.


    Therefore, although Titan with special installed aircraft is good, what the military really needs is not those special installed aircraft, but a general-purpose type capable of mass production and equipping the whole army.


    Therefore, Chen Xin did not spend his energy on how to mass produce the specially installed aircraft. Instead, he spent more energy on the new model of mass production general Titan.


    It not only improves the design, making it more convenient for production, but also optimizes the structure, simplifies the parts, makes it easier to maintain, and increases the durability of the body.


    At the same time, Chen Xin also formulated standards and specifications for Titan''s production process, adjusted and optimized the design of the production line, so that the country could establish new Titan production plants in other places, and gave relevant technology and design drawings to several major military factories, so that they could transform the production line as soon as possible to produce Titan.


    With such efforts, according to Chen Xin''s estimation, Titan''s production will be improved qualitatively in the future. He can produce 10 units a week here, and it should not be a problem for other places to produce 100 units a week.


    Although it may take a long time for the production efficiency to reach this level, it can solve the problem of Titan''s large-scale equipment in the end.


    As long as the military obtains a large number of Titans, it is believed that after stabilizing the war situation, it can start to plan a counterattack.


    When Chen Xin thinks about the counter attack, he is more worried about the superior individuals of the alien creatures that are hidden deep underground and have not been seen so far. Now these offspring are just cannon fodder, and even the mother is just the breeding machine and subordinate nodes of the alien creatures. Up to now, none of the superior nodes have been seen by human beings, and they will really enter the counter attack stage, These are all things that need to be considered.

 Chapter 674

    In the biological laboratory, the living samples of the three captured combatants are kept in a special cage provided by Chen Xin, and a group of biologists are studying them.


    The three combatants in the cage seem to be a bit depressed. This is not because they are overdrawn because of too many experiments. But since they were captured, biologists have tried various methods, but they have not found the food of these combatants, so that they have not eaten anything so far.


    This is, of course, very bad news for biologists.


    It took a lot of effort to get these three fighting sons back. If they starved to death, it would be a great loss.


    What''s worse is that if they don''t come up with anything, not to mention the military and Chen Xin, who have paid a lot to capture these three fighting sons, they will want to strangle themselves.


    However, it is a pity that the three fighting daughters did not eat anything. Even if they got all the food they could, they could not attract the attention of the three fighting daughters.


    Therefore, when Chen xinlai checked their research progress, he was faced with not only the three starved and depressed fighting offspring, but also the help from biologists.


    "Hiss, you are giving me a difficult problem!" Facing this problem, Chen Xin also felt very difficult: "how can I know what these alien creatures eat! It''s a question mark whether this kind of creature will eat anything on earth or not


    This is not to say that Chen Xin is shirking, but that he really can''t think of any good way.


    If biologists want better research instruments and more detailed analysis of alien organisms, it''s just a matter of words for Chen Xin.


    But it''s too hard for Chen Xin to figure out what they eat.


    However, in the face of Chen Xin''s complaint, biologists can only say bitterly: "we have no choice but to go to the doctor in a hurry. If we go on like this, these precious living samples will really starve to death."


    Hearing biologists say that, Chen Xin can only scratch his head and stick to it.


    He went to the container where the three living samples were held and carefully observed them. Then he asked the biologist, "have you ever collected their feces? Can''t we judge what we''ve eaten by analyzing the composition of feces? "


    "We also thought of this, but these alien creatures have never been photographed. They don''t even have excretory pores and cloaca. Even our previous autopsy of corpses didn''t find that there are excretory organs in their bodies, but only digestive organs, just like they just eat but don''t pull." When biologists say this, the expression on their faces is like a big joke.


    However, when Chen Xin heard biologists say this, he had a different idea and asked him, "if there is a kind of food that can be thoroughly digested by their stomach after eating, does that mean that there is no need to excrete it?"


    "Theoretically, it is, but it is not in line with the theory of biological evolution! It is impossible for biological evolution to evolve the whole digestive organ into such a closed loop, and there is no food in nature that can be completely digested and absorbed without excretion! " Although we think that Chen Xin''s hypothesis is possible, biologists obviously think that it is still impossible.


    However, Chen Xin shook his head and said to the biologist, "aliens are an ethnic group. These progenies are bred by the mother. If the progenies do not need to be digested at the beginning, it is possible for them to degenerate their excretory function as time goes on."


    "It''s possible in theory, but it''s possible..." biologists can''t help shaking their heads. Although there are all kinds of strange things in nature and all kinds of possibilities, it''s too exaggerated even if it''s an alien creature.


    However, Chen Xin has no extra idea about this, just to one side of the researchers asked: "we get back before the mother body is still well preserved?"? Get some maternal fluids and see if they eat them


    When Chen Xin said this, the biologists on one side naturally did not stop him. They thought that mammals lived by the secretion of the mother in their infancy.


    Take the human newborn as an example. After the newborn grows up to three to five months, with the improvement of intestinal function and the enhancement of digestive ability, if you only drink breast milk, it will be excreted for a long time.


    If Chen Xin''s judgment is correct, it is possible that they do not need excretion.


    But biologists still feel incredible and say with emotion: "how did this evolve? No matter how amazing natural evolution is, it is not enough to say that it has evolved such a thing, is it


    However, facing the exclamation of biologists, Chen Xin shook his head and said with uncertainty: "this kind of creature may not necessarily have evolved naturally, but may have been guided or interfered."


    "Guide, interfere? Academician Chen, do you suspect that this is an alien biological weapon? " Biologists have apparently come up with some sort of science fiction routine.


    "It''s possible, but it''s more likely that there are superior individuals with high intelligence in this group, which can guide and control the breeding and evolution of subordinate individuals. If there is a sense of cluster or similar to the existence of insect groups, they may gradually differentiate into this kind in the process of evolution." Chen Xin''s brain hole is obviously bigger. He thought biologists would make their own guess: "suppose that if organisms like ants can continue to evolve and evolve higher intelligence, and with the control of the queen over the ant colony, can they really not control the evolution and reproduction of worker ants?"


    "This..." biologists did not envisage such a possibility, but after a serious analysis, these biologists also had to nod their heads and answer positively: "it is really possible that, in terms of the Queen''s control over the ant colony, there is the possibility of adjusting the direction of ant colony reproduction and evolution by means of pheromones."


    While Chen Xin and biologists were discussing this issue, researchers also took the previously preserved maternal body fluid samples and put them into the container holding the living samples under the gaze of Chen Xin and biologists.


    In the eyes of the public, the three living samples finally showed the desire to eat.

 Chapter 675

    Although the successful use of maternal body fluids caused the appetite of three living samples, it did not change their fate that they would eventually starve to death.


    On the one hand, it is natural that only Chen Xin''s mother''s body, which they first captured, is on hand. Most of the preserved body fluids are used for analysis and research, and there are very few samples left.


    On the other hand, it is also because the body fluid left by these dead mothers can make the three living samples have the desire to eat, but it can not meet their eating needs.


    You should know that the size of the fighting offspring is no less than a cow, and the body temperature can reach 105 ¡æ in the limit state. Even if the body temperature is lower in the normal state, it is still much higher than other creatures.


    To maintain such a large body size and such a high body temperature means that the metabolic rate of the fighting offspring is very fast, because it is the only way to generate enough heat.


    However, in order to maintain a high-speed metabolism, a lot of nutrients need to be consumed.


    Although the body fluids of alien organisms contain a lot of nutrients, which are high-energy nutrients, the scarcity of them is a problem. There is another problem, that is, they have been thoroughly cooled, and most of the heat contained in them has been lost.


    Although it is not impossible to heat it up and feed three live samples, even if all the preserved samples are fed to them, it will not last long.


    So after analyzing the current situation, Chen Xin discussed with biologists and decided to complete all the established studies before they really starved to death, and by the way, dissect the three fighting progenies to study their physiological conditions.


    As for the consumption of valuable living samples in this way, it is indeed a very painful thing, but there is no way to do it.


    It is just the result of the analysis. Although it has solved some doubts and problems, it has also caused new problems.


    "Since these offspring are fed by their mothers, how can they maintain such a large population? Are there innumerable matrixes underground? " A biologist feels very incredible.


    "Not necessarily. It''s very likely that these progenies are just cannon fodder." Another biologist looked at the research report in his hand, shook his head and said: "judging from the corpses we have obtained, the vast majority of corpses seem to be born in a short time, and there is a big gap between the batch of samples obtained by academician Chen and them before."


    Hearing what the biologist said, others immediately asked with interest, "is there a big gap? How old is it? "


    "The difference in physiological function between the biological samples obtained by academician Chen before and the data obtained by dissection and analysis and the biological samples obtained by us after the war is almost 1.2:1. The alien creatures encountered by academician Chen at that time are obviously more powerful." The biologist handed the report to others and motioned them to pass it on: "and the most important thing is that the biological samples obtained after the war basically had a certain degree of gene collapse and organ failure, while the living samples captured by academician Chen did not have such problems."


    This phenomenon shows the problem is quite obvious, these biologists just a little analysis came to a surprising answer.


    "In other words, the individuals who are fighting with us on the battlefield are just cannon fodder. Even if they are left alone, they will soon die?" Some people have come to this conclusion.


    The biologist who pointed out this definitely nodded: "according to the calculation, under normal circumstances, that is, academician Chen, the kind of progeny they encounter can survive for more than 30 to 40 years, but on the battlefield, this kind of progeny will not survive for more than three months. It can be said that they are the cannon fodder that is catalyzed."


    For a moment, the meeting room became silent, and everyone was surprised by the fact.


    "It seems that the conclusion is very obvious. This kind of creature is indeed a biological group with human intervention, as academician Chen predicted before." Someone made a concluding speech, but the tone was very heavy: "now it''s only time to find out whether they are alien biological weapons or the higher biological groups speculated by academician Chen!"


    "Judging from the current situation, academician Chen''s conjecture is more likely. Instead of biological weapons, they show more biological habits." A biologist participating in the meeting expressed support for Chen Xin''s inference: "after all, at present, these alien creatures must have upper nodes, which is in line with academician Chen''s conjecture."


    So far, although there is no clear evidence to show the existence of alien superior nodes among the clues and evidence that humans have, according to the analysis of various data, it is easy to draw the conclusion that the superior nodes exist.


    "If only we could organize an attack and capture a parent or upper node! In this way, we can learn more information and fight back against alien creatures better! " Biologists were not the only ones at the meeting, one of the officers said.


    Some people immediately objected to the officer''s words, shaking their heads and saying, "it''s impossible. Academician Chen''s capture of living samples was difficult enough. Now, if we want to capture the upper node or mother, it''s only possible to go deep into the nest of alien creatures. But now we can''t attack it at all. Even if we force it, we will lose a lot, It''s not worth the loss! "


    "Let''s not talk about that. Let''s sort out the data and research reports on hand, put them together, and give them a detailed report on alien life." The person in charge of the meeting stopped the discussion and announced that everyone would sort out the final result and report.


    At this moment, the door of the conference room was suddenly pushed open. An officer rushed in and came to the officer who attended the meeting. He whispered something to him, which changed his face.


    The biologist noticed each other''s face and quickly asked, "what''s the matter?"


    "Nothing. I''m sorry. I''ll go first." The officer got up quickly and left the meeting room with the officers who came in later.


    After they left, they could still hear the sound of running in the corridor and the voice of one of them: "go to find academician Chen..."


    All of a sudden, it was obvious that everyone at the meeting was a little confused, but the person in charge was stunned for a while, but soon recovered, and said to everyone, "let''s finish the meeting. Let''s go back and do our work well. Don''t inquire about the things we shouldn''t inquire about. Our task is to study the ecology and weaknesses of alien creatures, and other things are none of our business."

 Chapter 676

    At this time, in the Honghu area of Hubei Province, the progenies of alien workers are constantly digging up the ice layer and pouring out from the bottom of the lake like tides.


    Honghu Lake is located at the junction of Hubei Province and Hunan Province, adjacent to the Yangtze River, which is a part of ancient yunmengze.


    After the rise of the whole blue star sea level, Honghu Lake has been connected with the Yangtze River and Dongting Lake, forming a whole.


    After the temperature dropped, nature was frozen into an ice sheet like Dongting Lake, and even connected with Dongting Lake.


    After the invasion of alien creatures, although the military also set up a defense line here, because it is close to Chen Xin''s city, and the troops there are well-equipped, which effectively curbs the attacks of alien creatures. As a result, most of the attacks of alien creatures are focused on that side.


    For example, the Honghu area is less aggressive. Although there are still a lot of alien creatures here, compared with other defense lines, the response here is relatively easy.


    After all, alien creatures are still pouring out from around Junshan Island, and Chen Xin''s city is the first place to contact and attack, and the surrounding areas need to let alien creatures run for a while to reach.


    But now, it is obvious that alien creatures have dug the channel from Junshan island area to Honghu area, and are pouring out from the bottom of Honghu Lake.


    Human beings have already seen the tunneling ability of extraterrestrial organisms. This is how the extraterrestrial organisms in the whole west Dongting Lake area emerge from the ground.


    But before Honghu area was mainly from the Junshan island near the extraterrestrial creatures, Honghu area did not have extraterrestrial creatures from the underground, so we subconsciously ignored this possibility.


    Although it is not that we are not unprepared, in the continuous attack of alien creatures, everyone''s energy is put on resisting the existing attack, so there is no extra energy to guard against the possible danger.


    In fact, even if there is a defense, it doesn''t work.


    The number of alien creatures is amazing. Even though Honghu area has been coping with it easily before, it is only relative to other areas.


    Although not tired to deal with, but also can not draw out the extra strength.


    So when extraterrestrial creatures come out from under the Honghu Lake, the whole defense line in the Honghu Lake area becomes precarious, even tottering.


    All the troops on the line of defense have been pushed up, and the troops that have taken turns to rest have been reorganized and then returned to the line of defense.


    However, even so, they are still very difficult to withstand the attack of alien creatures at this time.


    The commander stationed in this section of the defense line naturally called for help at the first time, but it took time for the reinforcements to arrive.


    Moreover, because alien creatures came out directly from the bottom of Honghu Lake, even the air force''s bombing could only cut off the original attack from Dongting Lake along the Yangtze River, but could not effectively contain the attack directly from the bottom of Honghu Lake.


    At this time, the soldiers on the front line can only resist with their flesh and blood.


    Although the artillery in the rear soon began to roar, just like the trench warfare in World War I and World War II, if it is a sea of people tactics regardless of the cost, even if there is enough artillery, it is difficult to completely suppress the attack of the other side.


    After all, in modern wars, such tactics have long been eliminated, and the armies of all countries will not use this method of using human life to fill in victory.


    But for alien creatures, the progeny is just cannon fodder. Even if the progeny is put aside, it will be consumed by itself. It''s better to put it into the battlefield as cannon fodder.


    As a result, although a shell explodes among the alien creatures on the battlefield, it can clear a large area of open space, but in the next moment, the open space cleared by the explosion will be filled by the following alien creatures, as if the shelling was just an illusion.


    Although the artillery in the rear continued to bombard with the momentum of discarding the gun barrel, which really reduced the pressure on the front line, with more and more new channels under Honghu, the attack on the defense line was also more and more.


    If there is no support, it will only be a matter of time before the whole line of defense collapses and collapses.


    Fortunately, at the first time when they received the request for help, the military was organizing reinforcements. The soldiers on the defense line sacrificed their lives to resist the attack of alien creatures and won the precious time. The first batch of reinforcements finally arrived.


    Many people were stunned to see several large helicopters pull down in front of the position and then drop the Titan.


    However, although the way of reinforcement is exaggerated, the effect is immediate.


    With this group of 50 Titans put into the battlefield, they soon cooperated with a wave of helicopter attack, and cleared a group of alien creatures in front of the position, so that the soldiers in this section of the defense line could take a breath.


    Although the investment of the 50 Titans could not change the war situation, and the advantages they created were soon offset by the influx of alien creatures, the arrival of reinforcements gave great morale to the soldiers fighting on the defense line.


    Moreover, this is only the first batch of reinforcements. Although the follow-up reinforcements did not arrive at the battlefield as soon as they did, they are coming one after another, which gives the front-line soldiers and commanders a little more confidence to defend the defense line.


    But these commanders also know that although the arrival of reinforcements can control the current situation, the situation will not be changed if we can not solve the problem of the continuous influx of alien creatures under Honghu Lake.


    After all, what the Honghu defense line needs to face now is the attack from both the surface and the bottom of the East Dongting Lake. The air force''s bombing can block the attack from the East Dongting Lake for a while, but not for a lifetime.


    In addition, more and more alien creatures dig through the ice beneath Honghu Lake, just as alien creatures have opened the underground passage to Honghu Lake.


    More and more alien creatures are gradually offsetting the advantages brought by the arrival of reinforcements, leaving the war situation still in a disadvantageous situation.


    "Damn, if only the passage at the bottom of the lake could be blocked!" In the command post of Honghu defense line, an officer hammered his desk hard. There were large red arrows on the map in front of him. At a glance, the large red arrows showed that the blue defense line was so precarious.


    Each red arrow represents an alien attack, and each arrow represents a channel to be found.


    It doesn''t need much professional knowledge, and it can be seen from the map that if we can''t find a way to destroy these channels, the attack of alien creatures will not stop.


    But it''s impossible to blow up the tunnel.


    So far, human beings have found many underground passageways for alien creatures, but only a few of them have been destroyed at great sacrifice, except for the one that Chen Xin bombed on Junshan island when he first met.


    Now there is no good way to destroy the underground passage of alien creatures.

 Chapter 677

    "Damn it, how did these alien animals get to the bottom of Honghu Lake?" In the rear headquarters, an officer with a general on his shoulder was swearing: "the troops deployed in Honghu area can''t resist such an attack at all!"


    In fact, it is not only the defense line in Honghu area that cannot be blocked, but it is difficult to find a defense line that can block this double offensive along the coast of Dongting Lake at this time.


    That is to say, Chen Xin''s city can resist this kind of attack by fighting with alien creatures in the empty city left behind after evacuating from the urban area. The defense line in other areas can only rely on heavy firepower and front-line troops.


    At this time, Chen Xin was also in the headquarters. After hearing the general''s complaint, he took a look at the map and said, "it should be dug along the groundwater layer. The groundwater is not completely frozen, and the soil layer is relatively soft, so it''s easier to dig. In terms of the alien species'' regardless of the cost, there is no problem in digging."


    "Is there any way to curb their offensive?" The general inquired about Chen Xin. Chen Xin''s miraculous performance all the time made him have special expectations.


    "Have you tried the bomb? Or will they shoot missiles into these channels? " Chen Xin put forward his idea.


    "The air force and rocket forces are trying, but it doesn''t work well." The general shook his head. Chen Xin''s method had been tried in other places for a long time: "although it is true that the passage can be collapsed, these alien animals don''t care about being collapsed. They can dig through the collapsed place very soon. Even if they can''t, they will dig in other directions. The passage can only be blocked for a while."


    "Well... That''s troublesome. If you want to get it done once and for all, it''s very difficult to change the current situation unless you can blow up the whole underground of Honghu Lake and make it impossible for alien creatures to dig through in a short time." Chen Xin also shook his head and blasted the whole underground of Honghu. Of course, he could do it, but if he wanted to do so, it was obviously not the decision that he and the general in front of him could make.


    The general also understood Chen Xin''s meaning, thought about it and said, "I''ll go to the high level and apply for the use of nuclear weapons!"


    In fact, the military had the idea of using nuclear weapons to solve the problem of alien creatures before, but it was not able to make a decision because of the possible impact of using nuclear weapons and the fact that it might not be able to effectively kill the alien creatures underground.


    Now both the general and Chen Xin understand that if they want to stop the emergence of alien creatures in the underground of Honghu Lake, they have to blow down the whole lake basin and let the foundation collapse to completely block these channels.


    If we want to achieve this, we can only use nuclear weapons to achieve such great power.


    After all, the Honghu area has just seen the emergence of alien creatures. If the lake basin is blown down, it can still stop alien creatures.


    Moreover, the area of Honghu Lake is much smaller than that of Dongting Lake, and the equivalent needed to collapse the lake basin is not so large, so tactical nuclear bombs can be used to achieve this goal.


    However, when the general was preparing to apply to the high level for the use of tactical nuclear bombs, Chen Xin was worried about other things.


    "Do you have a map of the groundwater distribution in the whole Dongting Lake area?" Chen Xin inquired to one of the staff.


    "This... We don''t have it. We''re going to find it." The staff officer rummaged through some maps in the headquarters, but did not reply to Chen Xin.


    Hearing this, Chen Xin shook his head. Instead of asking him to look for the map, he just turned his eyes to the map displayed on the large screen in the headquarters, frowning and thinking.


    After hesitating for a moment, Chen Xin said to the staff on one side: "let the surrounding areas have an inspection. I suspect that the alien creatures have not only launched an attack on the Honghu area."


    "Not only did they launch an attack on Honghu area? Academician Chen, why do you say that? " At this time, the general heard Chen Xin''s words and immediately issued a question.


    Only one Honghu area has caused trouble. Now the whole defense line has been affected. If there is another breakthrough, the general thinks it will be impossible to defend.


    "Since alien creatures can dig along the aquifer to Honghu Lake, they can naturally follow the aquifer and spread to other parts of the Dongting Lake system." Chen Xin said, pointing to the rivers flowing into Dongting Lake on the map.


    "Ah! That''s it When the general saw the direction that Chen Xin was pointing to, he immediately felt frightened and said to the staff on one side, "hurry up, release the warning according to what academician Chen said, and check the cities around the Dongting Lake water system!"


    Chen Xin''s worry is that aliens will dig underground water along the river flowing into Dongting Lake, and then spread to other places.


    If this is the case, the defense line set up by the military along the Dongting Lake will become meaningless, just like the bypassed Maginot defense line, and become a useless device.


    Moreover, Chen Xin''s worry is likely to become a reality, not just a groundless worry.


    After all, since alien creatures can launch attacks in Honghu area, who can guarantee that they will not launch attacks in other directions?


    Looking at the staff to convey the warning, General Chen Xinhe felt like he was on pins and needles.


    It''s just that they obviously can''t just wait here. Although the Honghu defense line under attack has gradually stabilized after mobilizing other troops to reinforce, it obviously can''t solve the problem.


    "Academician Chen, apart from using nuclear weapons to blow up the whole basin of Honghu Lake, is there any other way?" The general asked Chen Xin.


    Faced with this problem, Chen Xin hesitated for a moment and said with hesitation: "yes, but it''s more difficult than using a nuclear bomb."


    "What''s the way?" When the general heard Chen Xin say so, he asked him.


    It doesn''t matter whether it''s difficult or not. As long as we can solve the problem, we have to solve it no matter how difficult it is.


    In this regard, Chen Xin can only shake his head and said: "according to the previous anatomy and research of alien creatures, we can preliminarily determine that the alien creatures are all under the command of the upper node. If we can dispatch a troop to find out and eliminate the upper node, it is possible to curb the enemy''s attack."


    "Isn''t that beheading?" The general responded that this is the decapitation operation of raiding local headquarters with special forces commonly used in modern war, which immediately made him eager to try.


    However, Chen Xin shook his head again and said helplessly: "decapitation is a very practical tactic, but the problem is that we don''t know where the upper nodes of alien creatures are, and we don''t have a special force that can carry out decapitation. This method obviously doesn''t work."

 Chapter 678

    Finally, the high level approved the application for using tactical nuclear bomb, and planned to use an air launched missile to hit a tactical nuclear bomb into the tunnel on Honghu Lake, and then use nuclear explosion to destroy all the tunnels in the whole lake area.


    According to the calculation, the impact of the nuclear explosion will destroy most of the channels at the bottom of the lake. After the melting of the lake water, it will completely block the possible channels after cooling, which is enough to block the threat from the bottom of Honghu Lake in a short time.


    Aliens want to invade again unless they can empty the bottom of Honghu Lake again.


    At the same time, other areas have also found traces of alien invasion. According to the detected signs of alien activity, they have penetrated into the surrounding area of Dongting Lake, and the whole active area has covered more than half of the ancient yunmengze area.


    Even in Xingcheng, the capital of Hunan Province, and three towns, the capital of Hubei Province, two important cities have found underground signs of alien biological activities, which has put the two places into a considerable degree of tension and preparedness.


    In other cities in the Dongting Lake area, tunnels dug by underground alien creatures have been found one after another, and some cities have directly become new war zones.


    Under such circumstances, the high level had to make a decision to let the troops withdraw.


    "Let the troops retreat and let go of the line of defense?" Chen Xin didn''t understand this and asked the general in the headquarters.


    They have just received the decision of the high-level to withdraw the troops, which shocked Chen Xin greatly. He did not understand why the high-level should choose. The withdrawal of the troops undoubtedly means opening the way to the alien creatures and allowing them to drive straight into other surrounding cities, which will undoubtedly cause huge losses to the surrounding cities.


    Although it is said that alien creatures have spread from the underground along the aquifer to the surrounding cities, this is still not the reason for Chen Xin to give up the existing defense line.


    However, Chen Xin didn''t understand it. As a commanding general, he saw it more thoroughly than he did. He explained to Chen Xin, "academician Chen, it''s not that the country wants to give up, but that we have to retreat and readjust our defense line now."


    As he spoke, the general drew out the map and pointed to the major cities around Dongting Lake, which had been marked red on the map. He said to Chen Xin helplessly: "these cities are important economic and industrial cities in Hunan and Hubei provinces around Dongting Lake. Once they were invaded by alien creatures, they suffered great losses!


    When the state retreats its defense line, it is also to adjust its defense and focus on protecting these important big cities. Otherwise, if we lose these cities, not only will we lose a considerable part of our industrial production capacity, but also a large number of people will be affected, which will have a great impact on the country. "


    After hearing the general''s explanation, Chen Xin was able to understand it, but he still frowned and asked, "but once the defense line retreats, the range we need to defend will be expanded. With the current strength, we can''t completely block these alien creatures, can we?


    Once they cross the line of defense, they will expand quickly with the speed of these alien creatures. What can we do to prevent their invasion at that time? "


    Chen Xin''s worry is not unreasonable. Once the terrible breeding ability of alien creatures spreads, it will spread to other regions. At that time, it will not be one region that needs to be defended, but most regions of the country.


    "The problem is that even if we continue to stick to the defense line, we can''t completely block the expansion of alien creatures in this way." The general couldn''t help but show a wry smile and pointed to the cities marked red on the map and said: "these cities are behind the defense line. It''s reasonable to say that these cities can''t be invaded when we block the positive invasion of alien creatures, but now we still detect the traces of alien biological activities.


    Academician Chen, we don''t want to withdraw now! But we have to withdraw. If we don''t transfer the troops back, once the alien creatures break through these cities like Honghu, do you think we will put nuclear bombs in the city, or withdraw people to other places like this city? "


    Chen Xin also felt helpless because of the general''s words. At this time, he wanted to make a big killing weapon to kill all these alien creatures at once.


    But the reality is that he can''t.


    Although he can build powerful bombs or other destructive weapons, once that kind of thing is used, can it completely kill all alien creatures? Let alone, the damage caused by it will be quite serious, and the consequences will be borne by human beings.


    Chen Xin would not have chosen such an extreme way to solve the problem if he had not come to the end where there was no way.


    Before things get to the worst, it''s obvious that we can''t use this way in any case, which may have huge sequelae.


    But if it''s any other way, Chen Xin has no clue, or can''t ensure that he can kill all the alien creatures.


    After all, the breeding speed of these alien creatures is too exaggerated, and they all hide underground. If we can''t kill all the mothers and embryos once and for all, and eliminate the possibility of their continued breeding, we can''t eliminate the threat of alien creatures.


    This is no doubt unacceptable. After all, even if the vast majority of alien species can be wiped out in a short time, with their breeding speed, they will be on the same scale or even more exaggerated in three or two years.


    Therefore, Chen Xin must ensure that the threat of alien life can be eradicated once and for all. Even if his population cannot be exterminated, his threat to human beings must be eliminated.


    "If only there was a way to kill them all at one time. Now even if we throw nuclear bombs, we can''t guarantee to kill them all." Chen Xin hammered the table very reluctantly. His face was gnashing his teeth. He hated his helplessness in this matter.


    In this regard, the general could not comfort him. He only shook his head, called the staff on one side, and began to arrange the retreat of the defense line.


    After all, it is the defense line around the whole Dongting Lake area. Where to withdraw, where to continue to stick to, where to withdraw first, where to withdraw later, and where to withdraw after withdrawal


    All kinds of problems need to be coordinated and controlled by the general and the staff. There are so many things to do that there is no time to comfort Chen Xin.


    And Chen Xin didn''t need to be comforted. After a little venting, Chen Xin regained his spirits, left the headquarters and went to the biology research laboratory. Now he is eager to get the biologists'' research data on alien creatures and find out the way to deal with them.

 Chapter 679

    What was dropped was a 100000 ton tactical nuclear bomb with small equivalent. In addition, the missile was used to drill into the tunnel at the bottom of Honghu Lake and detonate it. Therefore, no mushroom cloud rose at the scene.


    But this does not mean that the power of this nuclear explosion is small, on the contrary, because the power of all the explosions is buried underground, and the damage caused by the nuclear explosion is eaten by all the alien creatures underground.


    The high temperature produced by the nuclear explosion directly melted the frozen Honghu Lake, and a large number of ice layers were directly evaporated into water vapor. The flame and impact produced by the explosion directly exploded a big pit at the original bottom of Honghu Lake, and the soil around the bottom of the pit was burned, becoming a glass like texture.


    The surrounding melted lake water poured into the explosion pit, a huge amount of lake water was still rapidly evaporated, turned into water vapor rising, but quickly frozen under the influence of cold air, turned into a large number of ice particles falling, and then again evaporated by the heat released by the fission reaction at the bottom of the lake, and so on.


    However, even so, a large amount of lake water flowed into the channel along the original channel dug by extraterrestrial creatures, together with the fire and impact generated by the explosion.


    Under the power of the nuclear explosion, the whole Honghu Lake is like a pot of fish soup directly poured into a red hot iron pot, which is directly boiled.


    But it didn''t last long. With the impact of the nuclear explosion on the bottom of the lake, most of the channels collapsed in a very short time.


    Although a large amount of lake water was evaporated, a considerable amount of lake water still deposited at the bottom of the crater formed by the nuclear explosion, and poured into the collapsed and non collapsed channels to submerge them.


    In the whole Honghu area, all the extraterrestrial creatures, both at the bottom and on the surface of the lake, were destroyed under the influence of this nuclear explosion.


    The fish on the surface of the lake fell into the melting water and were cooked directly. Even the meat was crisp and rotten, and the bone and meat were separated directly, forming a pot of thick soup. The fish on the bottom of the lake was not much better, except that the fish on the surface of the Lake evaporated together with the fish soup, while the fish on the bottom of the lake was boiled, and mixed with the fish soup and poured into the alien nest along the channel.


    I don''t know whether it is the good luck of human beings or the bad luck of alien creatures. Under this wave of flooding, the upper node of alien creatures responsible for commanding the invasion of Honghu area also died, resulting in the loss of control of alien creatures in the whole Honghu area.


    The fighting sub body and the worker ant sub body do not have high intelligence. After losing the command of the upper node, they continue to attack according to the previous command, but they obviously feel that they have changed from the fierce warrior who is not afraid of death to the beast who will flinch and fear.


    After losing the fearlessness of death, these alien creatures are just a group of wild animals.


    The soldiers on the front line felt this most obviously. Although they began to retreat gradually under the cover of the air force and artillery before the nuclear explosion, their battle with alien creatures did not stop until the light of the nuclear explosion lit up the whole Honghu Lake. Only then did they really feel the change in the state of these alien creatures and the huge difference in combat effectiveness brought by the gap between them.


    However, at this time, only the soldiers on the front line are aware of this change, and only Honghu area is affected. The alien creatures in other areas are still maintaining a strong offensive, unless a nuclear bomb is also sent to these areas in order to achieve the same effect.


    After using a tactical nuclear bomb, the military and high-level officials have no scruples. Considering the adjustment of the whole defense line, the military has also used tactical nuclear bombs in other places where alien biological activities have been detected and where alien biological invasion has occurred.


    However, the equivalent of these tactical nuclear bombs is not large. They do not reach the 100000 ton equivalent of Honghu. Most of them are small tactical nuclear bombs with only a few thousand tons of equivalent, just to destroy the underground passage of alien creatures.


    However, even so, at the moment of the nuclear explosion, the attack of alien creatures seemed to be like eating the EMP bomb, resulting in a short period of setbacks, just like their upper command node was down.


    However, unlike the state of direct loss of command in Honghu area, the offspring of alien creatures in other areas were affected for a short time, and they soon resumed the rhythm of attack.


    At this time, the military has not been aware of the opportunities and effects that this change may bring, and is still adjusting its defense line.


    The defense lines that were originally surrounded by groups shrank backward in the areas that had been penetrated and crossed, and were pulled into protrusions one by one, while most of the remaining defense lines that were not in the direction of breakthrough only retreated a little to avoid becoming protrusions and being surrounded by alien creatures.


    After this adjustment, the defense lines of the areas that are broken through by alien creatures along the groundwater layer become pockets. If you look at the map, the penetration attack by alien creatures is like a tentacle in the pocket, surrounded by three buns.


    That''s what the military wants!


    Now that we can''t stop it, let''s put it in and surround it with local advantages, and surround these alien creatures who have broken through the original defense line!


    The change of tactics also brings new advantages to the war situation, and the use of tactical nuclear bomb also makes mankind pull back a city in the battlefield.


    Relying on such tactics, mankind did not bear huge losses after withdrawing the defense line.


    Although the trace of alien biological activities has been extended to many cities around, but relying on the advantages of tactical nuclear bomb and local encirclement tactics, human beings still hold a new line of defense and keep the alien biological in the line of defense.


    But after all, it is the defense line adjustment of the whole Dongting Lake area. In some areas that were not the main attack direction of alien creatures, there are still some defense lines that were broken by alien creatures gathering heavy forces in a short time.


    Fortunately, this kind of breakthrough was only for a short time. Under the strong attack of the defenders at all costs, these breakthroughs were blocked, and things didn''t get out of hand.


    But the loss of the garrison is also quite large. After all, in the case of fighting with alien creatures, when the opponent uses the sea of people tactics, the garrison can only take human life to fight.


    After all, at that time, a large number of air force, artillery and missile troops went to support several major breakthrough battlefields. Such a defense line in ordinary areas could not get enough firepower support.


    However, in any case, there was no uncontrollable chaos in this time''s front adjustment. The military also achieved its own strategic goal and temporarily stabilized the unfavorable situation brought about by the breakthrough of Honghu area and the infiltration and bypass of several areas on the defense line.

 Chapter 680

    From the breakthrough in the Honghu area to the final stabilization of the situation, the fierce fighting lasted for a whole week, and more than 30 tactical nuclear bombs were used in the battlefield, which made Chen Xin think that the military was going to blow up an isolation belt with small equivalent nuclear weapons.


    In fact, the military would not be stingy if a nuclear bomb could be used to blast out an isolation belt and block alien creatures.


    But it''s a pity that alien creatures are not so easy to stop. Even if the channel is collapsed by a nuclear bomb, these guys with a large number of densophobia will still attack directly from the ground like a tide.


    The only way to collapse the underpass is to prevent them from bypassing the defense line and sneaking attacks from underground.


    However, after destroying most of the channels dug up by these alien creatures along the groundwater, their offensive was finally contained.


    This may also be because the exobiotics can catalyze a large number of lower progenies, but they need to be replenished due to the consumption of a large number of progenies after the nuclear explosion. Or because the battle line is lengthened, and most of the channels used to transport troops are collapsed, the offensive of the exobiotics is not as fast as it was at the beginning.


    Now all the defense lines are seizing the time to build permanent fortifications, in order to seize the time that can be slightly relaxed and build a solid defense line.


    Although it also relied on the defense line to block the fierce attack of alien creatures before, at that time, most of the defense lines were temporarily constructed because of emergencies. Even if they were later reinforced, they did not reach the level of permanent fortification.


    This time, the war situation has stabilized, and the offensive of alien creatures has eased. The military and high-level officials intend to take advantage of this time to strengthen the defense line and improve the overall defense capability, at least not to be easily penetrated and broken through.


    Because of the need to build the defense line, a large number of high-rise workers were transferred from the cities around Dongting Lake. The original cities were demolished or rebuilt according to different needs, and a large number of people were relocated to the rear of the defense line.


    It can be said that this time, although the military has stabilized the defense line and blocked the attack of alien creatures, it has even frustrated their offensive to bypass the defense line. Strategically speaking, this is a very successful counterattack.


    But similarly, human beings have lost the whole Dongting Lake area, and millions of people in several cities need to move, resulting in huge losses of industrial and agricultural production capacity.


    In particular, the ecological greenhouse planting area established in Dongting Lake area has been completely destroyed by alien organisms, which has a huge impact on food production.


    The impact of this incident is not only the Dongting Lake area and surrounding provinces and cities, but also the whole southern region.


    We should know that before the alien invasion, the country could plan to transform the Dongting Lake area into an important grain producing area in the whole southern region to supply the food and vegetable consumption of several surrounding provinces.


    But now, it''s all over.


    If the military and high-level officials did not use nuclear weapons in the end to block the alien creatures attacking Hunan and Hubei provincial capitals, the losses would be even greater.


    After all, the capitals of Hunan Province and Hubei Province are the two largest cities in the central and southern regions of China. They have gathered a large amount of industrial and technological production capacity. Once the loss occurs, it will be a huge blow to the country.


    Not to mention the combined population of millions in the two cities, small cities can also migrate, such a big city may involve the whole country, it is not easy to move or evacuate.


    So what the military can do is to defend these two cities by all means to prevent them from being attacked by alien creatures.


    Fortunately, relying on the ultimate means of human nuclear weapons, they have finally held the line of defense.


    Now the country can only find new suitable areas, rebuild the city and these production facilities, and restore the production capacity as soon as possible.


    But I''m afraid the impact of this wave of losses can''t be eliminated in a short time. Even if production is resumed, it will take at least three or four months, which also leads to the shortage of materials in all aspects.


    "Chen Xin, these are the materials distributed this month. Take a look. You need to sign it." Tang Tang puts a list of goods and materials in front of Chen Xin, indicating that he will sign after reading it.


    Chen Xin is not surprised. In the past, Tang Tang was responsible for signing all these things, but now there is a shortage of goods and materials. The person in charge of the goods and materials allocated by each department must sign for confirmation in person, so as to avoid problems or someone filling their own pockets.


    Therefore, these documents need to be signed by Chen Xin himself. Fortunately, Tang Tang usually handles these documents well. He only needs to read them once and then sign them.


    However, on the list of materials Tang Tang brought this time, the quantity of various materials was obviously less than that of the previous month.


    Although Chen Xin is not in charge of the affairs, he is still concerned about the distribution of materials. After all, Tang Tang comes to him with such a few things every month, so he has a little impression.


    This makes Chen Xin frown and ask Tang Tang Tang: "sister, what''s the matter? Why is there so much less material this month? "


    "The war in the front is tight, and the rear naturally needs to tighten supplies." Tang Tang sighed helplessly, pointed to the list on the novice Chen and explained: "because a large number of materials have to be transported to the front line for the construction of the defense line and the production of various equipment, in order to ensure the supply of front-line materials, the rear naturally has to reduce the material rationing.


    We''re fairly good. We''re in the leading position of Titan production and scientific research center. We can apply more when we make reports. Other places don''t have such good conditions. Now many places have begun to implement the wartime rationing system.


    Now, I have spent a lot of energy to keep the share of these materials. Otherwise, we will get even less materials this month. "


    After listening to Tang Tang''s explanation, Chen Xin also shook his head helplessly. Strictly speaking, they are in the front line, but after all, they are behind the line of defense. In addition, they are also production and scientific research units. Although they are also in the scope of ensuring material supply, they will still be affected to some extent.


    Moreover, Chen Xin took a closer look and found that the reduction was mainly due to the supply of vegetables and fruits. However, materials related to Titan''s production, such as steel, were only slightly affected. It can be seen that the country''s food production was the most seriously affected.


    Thinking of this, he only sighed, signed his name on the document, and then said to Tang Tang Tang, "let Professor Li work harder and let the ecological greenhouse on the other side of the Dome City operate as soon as possible. At least we should ensure the supply of food and vegetables in the city."

    Apart from these trivial matters, what Chen Xin is dealing with now is the military''s requirements for him, the improvement of the military''s existing combat capability of exoskeleton, and the development of power armor that is convenient for mass production.


    Exoskeletons and power armor are things that Chen Xin brought out a long time ago. With the efforts of scientific research personnel in the field of national military industry, both have been mass produced and promoted.


    The exoskeleton has been fully equipped with the military, and even the civilian version has been popularized in various cities, which provides considerable help for production and construction.


    But the exoskeleton is only the exoskeleton after all. Even if the armor plate is added to improve the performance and output, it is only the exoskeleton. It really plays a great role in fighting with alien creatures, but the role is really limited to some extent.


    After all, exoskeletons allow ordinary soldiers to lift heavy machine guns and use heavy machine guns as light machine guns, effectively killing alien creatures, which is really of great help to the war situation.


    However, when the alien creatures are close at hand and the two sides enter the stage of short combat, the alien creatures that need Titans to confront are not threats that ordinary soldiers equipped with exoskeletons can deal with.


    Because of this reason, although the defense line was held, the casualties of the soldiers on the front line were not small.


    For the same reason, the military and high-level officials agreed to use nuclear bombs at that time and withdraw the defense line. Now they have concentrated a lot of resources on building YONGGU fortification, in order to better resist the attack of alien creatures and reduce the casualties of soldiers.


    Of course, this is a very effective means, but in addition, some people have put forward different ideas, that is, to strengthen the combat effectiveness of soldiers, so that they can at least survive in the face of alien creatures.


    At the end of the day, this kind of opinion became a request for Chen Xin.


    In the face of this requirement, Chen Xin didn''t feel anything wrong. After all, this is a very reasonable idea. If more soldiers can be saved, it can also make the war situation more favorable.


    Just want to do this, but it is not so easy.


    It''s not that Chen Xin can''t do it. With the ability of the system, let alone being able to survive in front of alien creatures, he can do it even if he can open an unparalleled exoskeleton in the pile of alien creatures.


    But the problem is that it can''t be mass produced even if it''s made.


    In the final analysis, all the problems are the same as the difference between Titan''s mass production and special-purpose aircraft. What the military wants is equipment that all soldiers can be equipped with. It''s better to simply add modifications to the original equipment to achieve the effect.


    This not only plays the role of upgrading equipment, but also does not need large-scale replacement and re production, which is the best solution.


    But it is undoubtedly very difficult to achieve this.


    After all, the performance of exoskeleton is there. It is almost impossible to achieve the effect of greatly improving its combat power without major changes.


    Chen Xin is also familiar with the exoskeletons the military is now equipped with.


    Although its main structure was designed by military researchers themselves, and Chen Xin mainly solved the problem of energy, he is still familiar with it.


    As for power armor, it''s his favorite work. Even Titan today is developed on the basis of power armor.


    Therefore, Chen Xin is familiar with the exoskeleton and power armor, but it is also because of this familiarity that he clearly realizes that it is by no means simple to transform them to meet the requirements of the military.


    Therefore, Chen Xin gave up the method of seeking a breakthrough in the body performance, and changed his thinking and wanted to find a new way.


    After all, it is necessary to save the cost as much as possible, facilitate mass production and match with the original exoskeleton and mecha. Therefore, it is impossible for him to exaggerate. He can only break the routine and see if there are any other methods that can solve the problem and cost less.


    However, Chen Xin was puzzled.


    He has a say in what alien creatures look like. After all, he has faced up to them and participated in the anatomy and living experiment of the biology research group. He is quite familiar with these alien creatures.


    Therefore, Chen Xin clearly knows that without heavy firepower, even if ordinary soldiers have exoskeletons and power armor, they will not play any role in front of the fighting offspring of alien creatures.


    Exoskeletons are basically broken in one beat, and power armor is just a little stronger tin can.


    Therefore, confrontation is definitely out of the question, unless Chen Xinken upgrades every exoskeleton to the point where it can fight against alien creatures, otherwise it is out of the question.


    But in this case, regardless of the survival and materials required for the upgrade, it will take quite a long time.


    Since we can''t fight, should we try to escape?


    This idea flashed through Chen Xin''s mind.


    In the past, when playing games, there were usually several kinds of defense schools. One was dead pile defense, which made it hard for anyone to fight; One is the death heap attack, which takes seconds before the opponent kills himself.


    In addition, there is another way of thinking that is heap speed. If it is too fast for anyone to hit, it will not take damage. Even if it is a range attack, it can also have enough speed to dodge.


    Thinking of this, Chen Xin seems to have inspiration.


    Strictly speaking, the speed of an alien creature is not slow. It is basically the same as that of a horse. Although it can''t reach the level of a famous horse, the average speed of an ordinary horse is still OK.


    In exoskeleton, it is not realistic to achieve this speed without modification.


    Although it can''t be ruled out that a few gifted guys can achieve this kind of speed, in terms of body performance, they can''t achieve such a fast running speed.


    But the biggest difference between humans and animals is that we can use tools. If we can''t reach that speed by running on our legs, what about flying?


    If you add a nozzle on the exoskeleton, you can take off in a short distance when you are in danger. Just like the super jump in the game, you can instantly pull away the distance. Is that what you want?


    Chen Xinyue thinks more and more that this idea is feasible, and with the distance between the takeoff and the place, he can continue to shoot with heavy firepower to kill the enemy.


    And it doesn''t take much to remodel the exoskeleton, just add a backpack.


    Thinking of this, the inspiration in Chen Xin''s mind seems to burst out, so he can''t help but want to do one first to test it.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 682

    In an unfinished building in the Dome City, Chen Xinzheng and his research team are conducting a test experiment.


    The manufacture of the jet backpack is not a laborious thing for him with the hand holding system. It took him some time to make a jet backpack that can be hung on the exoskeleton, and also optimized the original military exoskeleton.


    Although the overall structure has not been greatly changed, Chen Xin has optimized some details of the exoskeleton, as well as the operating system installed on the exoskeleton, and added a flight control program to adapt to the jet backpack.


    After all, after the installation of the jet backpack, you need the whole person to fly like the super jump in the game. If you can''t control your posture in the air, it''s OK to land on your feet first. If you land on your face first, it''s a tragedy.


    Therefore, it is necessary to install gyroscopes in the jet backpack, install buffers in the legs to prevent the impact of landing from breaking the leg bones, and even add attitude control nozzles to prevent some rookies from breaking their necks.


    Chen Xin found an unfinished building as the test site. Soldiers wearing exoskeletons equipped with jet backpacks kept jumping between the floors of the building to test the performance of jet backpacks.


    "How does it feel to use a jet pack? Is there anything wrong with it? " Through the phone in his hand, Chen Xin contacted the soldiers who were constantly jumping up and down.


    "At present, it feels good. It can jump 50 meters at the longest distance and 10 meters at the highest. There is no abnormality or maladjustment." The soldier being tested gave Chen Xin a quick reply, which seemed to be very satisfied with the jet pack.


    However, a researcher monitoring the exoskeleton and testing the soldier''s condition issued a warning at this time, saying: "academician, it is detected that the nozzle of the jet backpack is overheated, so it is recommended to suspend the cooling!"


    "I see, tester. Pause the test and let the backpack cool down." Chen Xin issued instructions to the testers to suspend the test.


    Of course, it''s not an accident or a mistake. After all, the soldiers in charge of the test have been jumping up and down in the building for a long time. It''s normal for them to use it for a long time and overheat.


    But it also reflects that jet backpacks are not suitable for long-term continuous use.


    When the backpack cools down, Chen Xin asks the tester to come back to him, and then dismantles the backpack for further inspection to confirm the loss.


    "The loss of the nozzle here is a little serious. It seems that it can''t be used continuously for a long time. This point should be included in the use specification at that time." As Chen Xin disassembled the parts of the backpack and inspected them one by one, he told the researchers what to pay attention to.


    Although it is a product of rush work, there is no problem with the quality of this jet backpack. Although it has been used for a long time, it is still an excellent equipment.


    "Do you think this jet backpack can improve the survival rate of our soldiers in the battlefield?" Chen Xin reassembled the backpack and asked the tester in his hand.


    The testers are special forces who have been transferred back from the battlefield. They have already encountered alien creatures in the front line, and they have fought and fought with them head-on. They have a clear understanding of the combat effectiveness of alien creatures, and they also know how to save their lives in front of them.


    Asked by Chen Xin, the tester definitely nodded and said: "if you are on the battlefield and have a jet backpack, you can avoid the attack of alien creatures. However, you feel that the speed is a little slower when you take off. The attack of those alien creatures is very fast. If you can jump faster, the effect will be better.


    There''s no need to jump so far and so high. It''s a little useless in the battlefield. It may be necessary to jump high in the city, but it''s still too high to jump three stories at a time. Usually, one or two stories is enough. "


    Hearing what the tester said, Chen Xin raised his eyebrow and confirmed to him, "that is to say, you don''t think the jet pack can jump so far, but it needs to jump faster. Is that what you mean?"


    "Yes, on the battlefield, we usually encounter alien creatures who attack too fast to escape." The tester answered earnestly, and introduced to Chen Xin what happened on the battlefield: "in addition, on the battlefield, we can''t retreat so far all of a sudden. We can hide behind and roll to the side, but if we run back, it is likely to involve other comrades in arms around us and affect the defense line."


    Listening to the introduction of the tester and his gestures, Chen Xin seriously thought about it, nodded to him and said, "OK, I see. Your opinions are very valuable. I will revise them according to your opinions. Later, I will trouble you to test again. It''s hard for you."


    "Yes, academician!" The tester saluted Chen Xinjing, and then said to him, "this is what I should do. If I can develop new equipment, I can also make comrades in the battlefield sacrifice less. What can I do with my hard work? Academician Chen, you are really great!"


    "In other words, without your blood and sacrifice in front of us to block the attack of alien creatures, how could we have peace of mind to conduct research in the rear?" Chen Xin smiles and doesn''t say anything more. He just studies how to modify the backpack.


    The tester also stepped aside, resting and waiting for the next new test.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While Chen Xin was studying new equipment to reduce casualties on the battlefield, the situation that human dropping nuclear bombs would cause a setback in alien biological offensive in previous battles was finally sorted out and reported to the relevant departments.


    This is a very important piece of information, and it is also a very critical piece of information.


    If we can find the reason why nuclear explosion will affect the attack of alien creatures, it will undoubtedly give human beings more advantages in the battlefield.


    If it can affect the attack of alien creatures, or even hinder their attack, it will undoubtedly create more opportunities for the front-line soldiers, so that they can better kill these alien creatures.


    Even if we further study this topic, we may be able to find out how the upper nodes command the lower individuals, so as to find a way to win the war.


    And such an important task is naturally entrusted to biologists who have been studying alien creatures.

 Chapter 683

    It is a big problem for biologists why nuclear explosion affects the attack of alien creatures.


    The military can''t wait to figure out why, so that it can replicate the impact and gain more advantage on the battlefield.


    But it''s clear that they can''t just drop another bomb on the battlefield in order to reproduce this phenomenon.


    After all, the use of more than 30 tactical nuclear bombs has already filled the whole war zone with radiation. If you throw them again, it''s like the rhythm of turning the war zone into nuclear wasteland.


    Although the tactical nuclear bombs used now are not as polluted as the early nuclear weapons used in those years, for the sake of the health of the soldiers fighting in the theater, the military is still trying to avoid using nuclear weapons as much as possible.


    Since there is no way to reproduce what happened before by creating a nuclear explosion, biologists can only analyze it based on the available information.


    The first thing to be expelled is the possibility that the nuclear explosion killed the command node of alien creatures.


    After the analysis and judgment, it was determined that the collapse of alien creatures in Honghu area after the nuclear bomb explosion was the result of killing the superior command node.


    Therefore, after the nuclear explosion, the attack is not the same, and the possibility of the upper node being killed is eliminated.


    Although some people think that there is more than one upper node in other areas. After one of the nodes was killed, other nodes took over the command. In Honghu area, all the upper nodes were killed in a short time, but this statement is only possible and can not get everyone''s approval and support.


    More in line with the information collected at present, it is said that the impact after the nuclear explosion interfered with the command links of alien creatures, resulting in the interruption of their command.


    Although it recovered in a short time, the interruption caused a setback in the offensive.


    This statement has been recognized by many people, but it still lacks theoretical basis.


    So biologists have to find evidence to support that.


    And that requires them to test live samples of alien life.


    But the previous three living samples have been used up. Although biologists have obtained a lot of experimental data and valuable information, the three living samples are still not alive.


    Now, if you want to continue testing, you have to capture new live samples.


    Fortunately, this time the capture task does not need Chen Xin, but entrusted to the special team newly established by the military.


    This team is an elite team composed of specially installed Titans discussed by the military and Chen Xin before. All the members are from the ace Titan pilots carefully selected by the military, and the body is a special body that Chen Xin personally made for them.


    Although there are only eight people in the whole team, the combat effectiveness of eight specially installed aircraft is enough to fight against 50 general Titans.


    And this mission is also the first mission after the formation of this special team.


    This naturally made the members of the whole team very excited. After all, after obtaining excellent body, they only conducted several combat tests to familiarize them with the new body.


    They have not carried out any formal tasks, which makes them eager to prove that they are worthy of such a large amount of resources.


    Of course, excitement comes from excitement. Since these pilots are the elite selected by the military, there are no problems that can''t exist in reality, such as being reckless on the battlefield, disobeying the command, or neglecting the enemy.


    In addition, there are no boring roles such as the temporary recruits'' spearheads in the team to insist on their own opinions and refute everyone. Every member of the team is very clear about their responsibilities and positioning and is ready to carry out the task.


    For this special team''s first official combat, Chen Xin is also very concerned.


    After all, this team is built by him, and he also wants to know whether the team''s performance in the battlefield can meet his expectations.


    In addition, while this team is carrying out the task of capturing living samples, Chen Xin has completed all the research and development of the jet backpack, has finalized the design, and has made the first batch of equipment to a special force.


    And this special force will also carry out this mission with this Titan team. On the one hand, it is to assist the Titan team in carrying out the mission. On the other hand, it is also intended to test the actual effect of jet backpack through actual combat.


    Although this may be a bit unfair to the special forces, all the equipment must be tested in the battlefield to know whether it is really useful.


    Therefore, the special forces did not have any opinions on this, but gladly accepted the mission.


    Looking at the departure of the two troops through the monitor of the headquarters, Chen Xin couldn''t help getting nervous, which made him more nervous than the last time he went to catch the living samples himself.


    "Academician Chen, are you concerned? Don''t worry, our soldiers are good, and this time we have made enough preparations, there will be no problem. " In the headquarters, the officer in charge of the operation was the same person who was in charge of the operation last time. Aware of Chen Xin''s nervousness, he began to comfort him.


    Chen Xin sighed and said helplessly: "the equipment used by these soldiers are all put into actual combat for the first time. If there is any problem, I can''t face their families."


    "The equipment you have developed, academician Chen, is certainly no problem. But for the equipment you have developed, academician Chen, we would not have been able to defend this war." When the officer heard Chen Xin say so, he felt immediately.


    For ordinary soldiers, if they don''t have exoskeletons, they have to cooperate with at least two or three people to control heavy firepower, and they are not flexible at all.


    No one can fight on the battlefield with the strength support provided by exoskeletons.


    If it''s the same kind of ordinary equipment as the assault rifle before, maybe the alien creatures have already broken through the defense line.


    Because of this, the military attaches great importance and gratitude to Chen Xin, and officers do not want Chen Xin to have any psychological burden because of equipment problems or failure to meet the requirements, resulting in casualties.


    It''s just that this kind of problem is very difficult for professional psychologists to deal with, let alone military officers who are good at fighting.


    So after a few words of consolation to Chen Xin, the officer gave up and began to concentrate on directing the battle.


    However, he was still thinking about whether to make a report to his superiors and let them send someone to guide Chen Xin.


    After all, the importance of Chen Xin now is self-evident. If he has a problem with his mentality, it''s a great event.

 Chapter 684

    After arriving at the mission site, the special forces equipped with jet backpacks did not immediately start operation, but quietly waited in the standby area, waiting for the special team to work with them.


    The location of this capture mission is different from that of the previous one. It is not in the city, but in a battlefield on the defense line.


    "What do the superiors think about directly capturing prisoners on the battlefield? Can you hold it? " A soldier who is leaping forward whispers in the team channel.


    Because it''s a complaint, he only dares to say it on the team channel, not to speak nonsense to the whole theater on the regional channel, not to mention the command channel where only the commander has the right to speak.


    But also because it is only their own tactical team can hear the team channel, talk can also be less scruples, can complain about what.


    "To avoid something like last time? Last time, I heard that an armored force and a Titan combat team were sent out to capture the city. As a result, those alien beasts directly attacked, and they almost didn''t stop them. " A little more informed teammates also whispered the news they heard on the team channel.


    Although they are on the battlefield, the usual iron discipline and strict training make them not the amateur level who will chat before the task.


    It''s just that we are on standby at the rear of our own defense line, and the previous command channel''s instructions are also on standby. It''s not against discipline to chat for a while.


    "Those alien beasts!" There was a curse.


    But at this time, we are more concerned about their mission. Although we have heard the mission briefing, we know that the mission this time is to let the comrades in the front defense line open a gap and let a small number of alien creatures come in. Then they set up a pocket array in the rear of the defense line and together with another special force to capture this small number of alien creatures as much as possible, Help comrades on the front to plug the gap.


    But this tactic is still worrying. What should we do if the defense line is really broken through.


    But this kind of thing is not what they should consider. If there is an accident, what they can do is to fight back the alien creatures.


    "It''s easy to use this new equipment! It''s like flying when you use it. " Soon the topic will jump to their new equipment of spray painted backpack.


    As for the new equipment issued just before this mission, although everyone is not very familiar with it and does not know how to use it, the soldiers of the special forces are very satisfied with the equipment itself.


    They have actually been to the battlefield and fought. Naturally, they know how useful this kind of super jump equipment is.


    Once used well, we can have one more life at the critical moment.


    And with this thing, many tactics and operations can become completely different, so that they have more tactical options.


    "If only they had spray painted backpacks earlier, they would not have sacrificed." Several people chatted and talked about their comrades in arms who had died. It was a pity for them. If they had jet backpacks at the beginning, maybe several comrades would not have died.


    However, this kind of words is just a sigh. They are all soldiers. They may not be able to say that they are ready to sacrifice for their country from their first day in the army. But for these special forces, they are really ready to die for their country every time they perform a mission.


    "Don''t say that. We didn''t have the ability. Otherwise, even without advanced equipment, we could have rescued Dongzi." They are old comrades in arms who trust each other with their lives and know their roots. There is no taboo in talking about the past, so they are more direct.


    It just made the atmosphere a little dull, and no one spoke any more.


    They waited for some time, and only a few helicopters from another special team arrived at the scene.


    Seeing the special team transported by helicopter, the people in the special forces were surprised.


    They originally thought that their jet backpack was the new equipment invested by the country in this mission, but they didn''t expect that they were just the foil. The real new equipment was this special team.


    Eight new specially equipped Titans were transported by four specially designed Titan transport planes. After releasing the fixed clasps, the eight Titans directly hit the ground.


    Looking at the eight special Titans with different colors and shapes from ordinary Titans, the special forces can''t help but wonder, when did the country secretly develop these things?


    Although Chen Xin did have a variety of Titans when he first got up for disaster relief in Southwest China, and there were all kinds of Titans, after Titans began mass production and were equipped in the army, they quickly unified the model and coating, and there was no mess before.


    That is, when the scientific research center is still doing research on new models, it will do some new experimental models for testing.


    But now it''s war time. It''s obvious that these Titans, which are not mass-produced, suddenly appear in large numbers on the battlefield. It''s hard not to think about secret weapons or special forces.


    Some people even murmured in their hearts that the country is not going to test new equipment this time, is it?


    Although as a special force, they have also helped the country to test a lot of equipment, but this kind of equipment has never been tested in actual combat, and their teammates are also gaudy, which really makes the soldiers of the special forces feel a little nervous.


    For the sake of confidentiality, only the commander of the special forces knew some general information about the Titan equipped by the special team, and did not inform the soldiers.


    After all, there is a higher level of command, and the grass-roots units only need to obey the command.


    The commander of the special forces and the leader of the special team had a simple exchange. The superior had worked out the combat plan before and distributed it to them. In addition, this time, the mission had a clear goal. They were mainly familiar with each other, so that they could cooperate in the fight later.


    After they have confirmed and both units have adjusted, the commander of the special forces will take his soldiers into the preset position and get ready for the battle.


    The eight titans of the special school team came close to the defense line, ready to block the defense line and finally capture after opening the door for alien creatures to enter.


    While they were ready, the troops on the front line were also informed that they were ready to open a hole in the line.

 Chapter 685

    This time, the battle is much smoother than expected.


    On the one hand, the special forces equipped with jet backpacks played an outstanding role. Relying on the battlefield mobility advantage brought by jet backpacks and the large caliber heavy firepower they carried, they well annihilated the alien creatures that were put into the defense gap, and cooperated with the special team to complete the capture task.


    On the other hand, the specially equipped Titan, which is also equipped by a special team, has great power, blocking the gap of the defense line, blocking the attack of alien creatures trying to break through the defense line, and causing quite effective damage to it.


    The result of the combination of the two is that more than 20 individuals of alien creatures have been captured, transported back to the research institutions in the rear and handed over to biologists.


    In addition to the combat progeny, there are also several worker ant Progenies and a valuable vesicular progeny.


    Chen Xin was very surprised that these special forces were able to catch the vesicles.


    So far, human beings have only seen this kind of progeny from a distance on the battlefield. What Chen Xin had obtained was an embryo that had not yet hatched. This was the first time that they had come into close contact with the special existence of vesicular progeny.


    Just seeing the appearance of the vesicular body, Chen Xin''s face became very blue, and other biologists along with him also became very ugly.


    This is because there is a "cannon" composed of biological exoskeleton structure on the back of the vesicular body.


    It''s a cannon in the literal sense. Although the outer shell is closed, and the "cannon tube" itself can''t be seen from the outside, Chen Xin has provided biologists with a scanner that can scan the biological body structure. At this moment, they can see clearly the "cannon" composed of endoskeleton and muscle under the shell on the back of the vesicular body.


    Although the nature is uncanny, in the process of natural evolution, there are always a few species that will release themselves and evolve into monsters such as echinoderms, if you want to say that natural evolution can evolve a good creature into a biological cannon, I''m afraid not Darwin would have to sit up like Newton from the coffin.


    In particular, the four legs of the vesicular oophore have evolved into a rather stout appearance for the purpose of fixing the body. It looks even more like the legs of an elephant. After carrying a barb and being able to get stuck in the soil, Chen Xin feels that if this is a natural evolution, he can dip all the biological teaching materials in soy sauce as a sashimi.


    "This... This..." a biologist was very excited. He pointed to the vesicle in front of him and said in surprise, "how can there be such a creature?"


    "It seems that this is an alien invasion, not the biological invasion we started to think about!" A biologist who thought that aliens might be just a biological population, but the lower offspring were influenced by the higher individuals to control the direction of evolution, also felt that this was really something that could not grow out of natural evolution.


    "So is this alien biological weapon? It''s amazing that a cannon grows directly. At first, I thought they used spitting to launch vesicles Another biologist at this time also felt the appearance of three views subversion.


    Although the existence of vesicles has been found in the battlefield before, and these things have not been eliminated in the battlefield, this cannon is really something they have never seen before.


    After all, since the gun can be retracted to the inside of the vesicle body, it obviously won''t stretch out all the time.


    When they encountered vesicular bodies on the battlefield before, they didn''t use searchlights to shine on them. At first, they thought they were just special creatures, and there were no animals on earth that could launch liquid as a means of attack. Biologists didn''t feel surprised about this.


    But now we see that the vesicle progenitor not only emits vesicles by spitting as they think, but also grows a cannon on its back with a shell that can cover the cannon. If everyone thinks that this is something that can be evolved by natural evolution, then he can really rewrite the theory of evolution.


    "I suggest that this living specimen be dissected! There must be traces of alien biological transformation on this unnatural creature! " A biologist came up with a more radical idea.


    Chen Xin hesitated for a moment, looked at the other biologists around him, but no one objected. After thinking about it, he nodded: "in that case, send it to the anatomy room. I also want to know how this kind of creature grew up like this."


    After hearing Chen Xin say so, the researchers and biologists at the scene didn''t hesitate to ask people to push the cage with vesicular bodies and send them to the dissecting room. Chen Xin also followed suit. After disinfection, he put on his surgical clothes and entered the dissecting room, hoping to see the dissecting process of the creature with his own eyes.


    Biologists first injected a large number of powerful anesthetics into this vesicular progeny, which they had tested on previous living samples. It can effectively paralyze alien creatures, at least in combat progeny.


    With the injection of anesthetics, the vesicle passed out as they expected.


    Only with the help of the crane and other equipment in the dissecting room and several heavily armored staff, did the biologists put the vesicle on the dissecting table.


    One of the biologists took a look at the others with a chainsaw in his hand and got the signal of "ready to go up" from Chen Xin. Then he held the chainsaw, poked it into the neck of the body and saw its head off.


    Looking at the scene of blood splashing, Chen Mo helplessly shook his head.


    It''s not that we have to be so cruel, but the outer skin of alien creatures is quite thick. Even if it''s not as strong as the chitin exoskeleton, it can''t be cut open with a scalpel.


    So when we dissected these alien creatures before, we started to use tools like chainsaws.


    As the head of the vesicular body is cut off, its life activity stops.


    After confirming that it was dead, the two biologists climbed on the back of the oogonium, found the shell used to cover the gun door, and pried it open with a crowbar.


    Seeing the red cannon under the pried open carapace, everyone swallowed unconsciously, which was really frightening.


    "Hook out the barrel and measure it." Chen Xin said to the biologist standing on the back of the sporophore.


    So, in the eyes of everyone''s surprise, the gun barrel made of muscle and bone on the back of the vesicle body was pulled out of the body by two biologists with hooks.

 Chapter 686

    Under the dissection of biologists, the "cannon" on the back of the vesicular body was stripped off.


    After dissection, biologists determined that this is a pipe with a length of about two meters composed of endoskeleton and muscle. It really belongs to something that can grow on organisms, but there is no serious organism or natural experience to grow such an organ on itself.


    As for its working principle, it compresses the huge lung chamber connected with the gun tube through muscle contraction, which is similar to the way that children have played with ejecting paper balls through their nostrils to eject bubbles filled with high-temperature corrosive liquid to attack the enemy.


    In addition, the vesicles ejected were not what Chen Xin had expected at the beginning. Spheres were formed in the vesicle daughter body one by one.


    They are stored in a gland in the form of liquid. When it is necessary to spray vesicles, these high-temperature corrosive liquids will be injected into the gun barrel through the gland. At the same time, the gland will secrete a kind of mucus to wrap the high-temperature corrosive liquid and harden after contacting with air, which forms the vesicles seen by humans.


    "It''s more primitive than we expected, but it''s not something that may grow out during the evolution of normal organisms." a biologist looked at the "cannon" that had been completely torn apart in front of him and shook his head seriously: "Although animals will evolve glands or organs for spitting, it is completely a gun tube, or even the whole body will evolve into a cannon. It is absolutely the result of biological transformation."


    "But we haven''t found any traces of artificial induction!" another biologist showed a flat plate in his hand, which showed all the examination results of vesicular daughters after being dissected.


    To everyone''s surprise, they did not find any trace of artificially induced growth in the vesicular progeny, just like the anatomical results of the previous battle progeny.


    It''s like God made a big joke. The vesicle and combat daughters really grow like this naturally.


    But when Chen Xin listened to the biologist, he shook his head and said, "it is not necessary to induce growth. Gene compilation can achieve the same effect, even pheromone induction can achieve the same effect.


    What''s more, it doesn''t matter how alien creatures do this. What matters is that they grow up like this is not the result of natural evolution, which proves that they are not beasts, but a civilization.


    We must adjust the strategy of fighting them. We can no longer treat alien creatures as a kind of beast or animal, but should treat them as a dangerous invasion of interstellar civilization and guard against their attack with a more rigorous and cautious attitude. "


    "Academician Chen is right. Our focus now is not on how extraterrestrial creatures grow like this, but on how much trouble they will bring us and how we should deal with them!" a scientific researcher agreed with Chen Xin,


    In his opinion, it doesn''t matter whether aliens grow up naturally, genetically modified, or made by other means. What really matters is how humans deal with these aliens and how to eliminate them.


    Although in the sense of research, it is not meaningless to study how extraterrestrial creatures grow into what they are now, whether they are naturally evolved or artificially guided, and even have great scientific research value. Maybe we can find a way to defeat extraterrestrial creatures, but for today''s humans, they can''t waste their resources and time on it noodles.


    Of course, it is of great significance for human beings to verify that extraterrestrial organisms are not naturally evolved creatures. At least human attitude towards extraterrestrial organisms has changed from eliminating pests to resisting aggression.


    If extraterrestrial creatures are just beasts, then humans just take the attitude of eliminating the termite nest in their backyard.


    Although the proliferation of termites may cause the house to collapse, it is difficult to directly threaten a person''s life, so even if termites appear in the yard, humans usually don''t rush to deal with them.


    As far as human beings are concerned, although the invasion of alien creatures has made human beings have the determination to demolish and rebuild the house and clean up termites, they do not start to demolish the house immediately, but intend to arrange everything step by step.


    But the invasion is different. It''s like someone broke into your house with a stick in open fire to kill you and rob your house and property.


    At this time, you will do everything you can to resist, kill robbers and protect your life and property.


    Human beings are now transforming themselves from the former model to the latter model.


    This transformation affects all aspects. The whole country and society are not only transformed into a wartime system and various means such as material rationing, but also twist the whole nation, the whole country and even the whole human civilization into a whole to fight against alien creatures as much as possible.


    The most intuitive manifestation of this is that Lucia also joined the battle and sent their reinforcements.


    The situation in Lucia was really bad before, but with the assistance of Yanguo, especially during the months when Chen Xin personally stayed in Lucia, their situation has changed greatly.


    The newly built shelter provides a good and stable living environment for ordinary people. The food produced in the greenhouse feeds everyone. The energy emitted by the energy tower is warm and stable, which provides enough energy to ensure that everyone will not freeze to death or live in the dark.


    With these, Lucia gradually recovered.


    And this country, nicknamed the fighting nation, does have resilience in the face of disasters and difficulties. As long as they are given hope, they will soon burst out unimaginable strength.


    Just as they were able to create suvia that frightened the whole world, the recovered Lucia also broke out amazing strength, and they rebuilt their country with considerable enthusiasm.


    While rebuilding their country, the lucians did not forget to help their country in difficulties, and the high-level leaders of the two countries have always maintained contact.


    At the beginning of the alien invasion, the lucians asked Yanguo if they needed help. At that time, Yanguo thought it could deal with it, but declined the kindness of the lucians.


    But now, when the alien invasion has become an alien civilization invasion that threatens human survival, as a part of human civilization, lucians have joined the battle.

 Chapter 687

    "I''m really surprised that lucians would send troops to the war." looking at the Lucian army entering the camp, Chen Xin expressed his surprise to the officers next to him.


    "This is a salute to your country''s help to our country before, and the invasion of alien creatures is related to all mankind. Even if Lucia will not be affected by alien creatures for a while, we can''t sit back and watch aliens invade the earth." the Lucia officer next to Chen Xin replied very seriously.


    For this answer, Chen Xin nodded slightly.


    Although he had some doubts about the lucians sending reinforcements and doubted the purpose of the lucians, it was not a bad thing to have more available forces at this time.


    After all, even if Lucia had any other ideas, it was only a matter within humans. They would not surrender to alien creatures.


    And even if they want to surrender, how to communicate with alien creatures is still a problem.


    "Academician Chen, how will our soldiers join the battle? Will they join the battlefield as an independent force or join your forces to fight together?" the officer of Lucia asked Chen Xin.


    This should have been the responsibility of the military, but the lucians obviously don''t have the configuration of an exoskeleton and a 12.7mm heavy machine gun like Yanguo. They can''t directly go into the battlefield. That''s to let the lucians die.


    Therefore, during the high-level discussion on how to arrange the lucians to participate in the war, the proposal to upgrade the equipment for the lucians was naturally put forward.


    This matter was handed over to Chen novice to evaluate the equipment of lucians.


    According to the evaluation results, there are two different treatment methods.


    "How are your equipment?" Chen Xin asked the officers in Lucia about the situation


    Although from the current situation of Lucia''s army, they can only go to death in battle, we still need to understand the situation.


    "Because we received the information shared by your country, we learned about the performance of alien creatures on the battlefield. Therefore, our army is equipped with heavy weapons as much as possible. Just because we lack the popular exoskeleton equipment in your country, we can''t make every soldier equipped with heavy firepower." at this point, Lucia''s officer shook his head and showed a bitter expression.


    Once upon a time, Yanguo still needed to introduce military equipment and technology to suvia. In only a few years, Lucia had an essential generation gap with Yanguo.


    However, although I am sorry, the question still needs to be answered. Therefore, Lucia officer took Chen Xin into the military camp temporarily allocated to Lucia''s army, and took him to see the current equipment of Lucia.


    Lucians really can''t equip everyone with heavy weapons, and they don''t have such advanced exoskeletons as Yanguo, but they still equip the army with unpowered booster exoskeletons and let the soldiers carry large caliber weapons as much as possible.


    However, they have been adjusted to armor piercing bullets, shotguns, grenades and other equipment, rather than small caliber weapons such as automatic rifles.


    In addition, they also brought a batch of tanks and armored vehicles. Although they also know that these armored forces can be of limited use and can''t be compared with the titans of the burning country, they can''t help it.


    After Chen Xin simply browsed around their equipment, Chen Xin also had some ideas in his mind.


    "Although your equipment can also pose a certain threat to alien creatures, it is still difficult to pose an effective threat on the battlefield." Chen Xin did not have any vague meaning about this kind of thing, and made it clear to the lucians: "So either you stay behind and do some auxiliary work to assist our troops in the front, or upgrade your equipment so that you can fight against alien creatures."


    "Upgrade equipment? This... Is your country willing to provide equipment?" Lucia''s officer seemed to be surprised. Before coming, he was ready for his troops to go to the battlefield with these existing weapons.


    After all, they are the wool, and they can beat the race of the bear by boxing. Even if they are shovel, they dare to charge, even now they have weapons.


    But now listening to Chen Xin''s meaning, it seems that Yanguo is willing to upgrade their equipment, which is really a surprise.


    "I can''t let you go up and die! This is not an internal struggle of human beings, but a war with alien creatures. As an available force, you always want to make you play the greatest role. Even if it''s a real mission to die, you have to play enough role, don''t you?" Chen Xin did not shy away from the issue of death, because such a task would really appear in the war.


    Lucia''s officers obviously knew this too. They didn''t care too much about Chen Xin''s death, but more about Chen Xin''s equipment.


    "Will you provide the same equipment as your army?" Lucia''s officers still looked forward to it, although they knew it was only an extravagant hope.


    "I''m not sure about this. Although I''ve been ordered to evaluate your equipment status and decide whether to provide weapons for you, what kind of weapons and equipment to provide still needs to be discussed and decided by my superiors." Chen Xin replied to the officer in Lucia.


    Despite the fact that Chen Xin himself could decide what kind of equipment to provide Lucia''s army, he still didn''t do such a thing.


    It is a matter that needs careful consideration to provide weapons equipped by one''s own army to the armies of other countries.


    Even if they are now facing the invasion of alien creatures, it still needs to be taken seriously. After all, Yanguo and Lucia are still two countries and have not completely formed an alliance under the threat of alien invasion.


    According to Chen Xin''s assumption, the equipment provided by the state to this reinforcements in Lucia should be civilian exoskeletons with heavy machine guns, while power armor and Titan will not be provided to the Lucian army.


    After all, Lucia''s army is also going to the battlefield. It is inevitable to improve their output and damage ability to alien creatures.


    However, the military exoskeletons in Yanguo are not enough, and there are not so many provided to Lucia''s army, so it is more appropriate to use civilian exoskeletons.


    As for Titan and power armor, not to mention that the use and maintenance require professional training and consume a lot of time. The output of these two alone is not enough to meet the needs of the inflammatory country itself. How can they be provided to the armies of other countries.


    But even so, it is much better than the equipment brought by the lucians themselves.

 Chapter 688

    "Hey, Vasili, have you heard? The people of Yanguo are going to change our clothes." in the canteen of the military camp, Vasili just had a lunch and planned to find a place to sit down and enjoy the "rich" lunch that Lucia couldn''t eat. A comrade in arms pushed him from behind and told him the gossip.


    Vasili was not too surprised. He just carefully protected his lunch and found an empty seat to sit down with his friends before he said: "This is not a strange thing. If the Yanguo people don''t want us to go to the battlefield, just to die or drag them down, they can only improve our combat effectiveness and survival rate, or simply throw us behind."


    "That''s right!" Vasili''s friend also sat down, but he obviously didn''t care much about dressing up: "but even without the equipment of the Chinese people, I can kill those alien beasts!"


    As he spoke, he also compared a strength posture to show the muscles on his arm.


    Looking at his friend''s figure similar to that of a bear and his physique that can really fight with the bear, Vassily didn''t doubt what he said.


    But he shook his head and said, "the combat effectiveness of alien creatures is very strong, and according to the people of Yanguo, those guys have shells on the surface of their bodies. Small caliber rifles can''t be pierced at all. If they don''t use large caliber weapons, they can''t be killed at all."


    "There is no monster that can''t be killed. It''s just that the people of Yanguo are too careful. If you want me to say, I should send a bazooka and blow up these alien beasts with a rocket launcher." my friend shouted at me as he stuffed food into his mouth.


    Vassily had already seen the strange, shook his head, and bowed his head to eat his own lunch.


    While they were having lunch, the canteen suddenly became noisy. Many people crowded towards the door. It seemed that there was something attractive outside.


    Vasili and his friend looked at each other. They grabbed a soldier passing by and asked him, "what''s the matter? Is there anything outside?"


    "The Yanguo people sent some alien monsters to show us what the alien monsters are all about." the soldier replied to Vasili, then broke free of his hand and continued to run towards the door of the canteen.


    When Vassily and his friends heard the news, they all put the food on the table into their mouths. Then they stood up and ran outside.


    In today''s era when there is no abundance of materials, the waste of any bite of food is a sin.


    Because the external ambient temperature is too low, there is a corridor between the canteen and the outside. This is a corridor built of transparent glass. The temperature is lower than that in the canteen, but you can see the situation outside.


    Pushing through the crowd, Vasili came to the glass window and looked at the open space in the center of the military camp. Several transport vehicles were unloading goods. They were containers like iron cages. You could vaguely see that there were huge creatures in them.


    "That''s an alien? It looks so big!" Vassily''s friend crowded in and looked at the containers.


    "It''s really big, but the equipment of Yanguo people is more surprising than those alien creatures." Vasili was more careful than his friends. He noticed that the containers that seemed to hold an elephant were carried down from the car by four people.


    Before becoming a soldier, Vasili worked as a warehouse porter for pocket money in his school days. He clearly knew that such a large box was something that could only be moved by forklift or crane in the past.


    If you want to carry such a big thing by manpower, even if it is empty, it is only made of very light wood, and it can''t be carried by just four people.


    Obviously, these four people are equipped with quite advanced power equipment.


    Thinking of the passive assisted exoskeleton issued by the army before he came to Yanguo, Vasili easily guessed that the four box carriers were equipped with the dynamic exoskeleton demonstrated by Yanguo people in Lucia.


    In addition, several tall figures around the transport vehicle are undoubtedly the military equipment of Yanguo people.


    "Hey, Chekov, do you remember the two big robots they sent out when the Chinese people came to rescue the capital?" Vasili asked his friend.


    When Chekov heard Walisi''s question, he definitely nodded and replied, "of course, I remember that the two big guys were fierce at that time. I saw them smash through the barricade, push away obstacles, and even use shields to resist small caliber shelling. What''s the matter? Why do you suddenly ask this?"


    "Yan people are escorting these alien creatures with that big guy. Why do you think?" Vasili frowned at the tall figures around the transport vehicle.


    "Either show us the force and let us understand that the Yanguo people now have a strong force, and Lucia is not the opponent." an officer nearby heard their conversation and interposed: "either these alien creatures are too dangerous. They should ensure that there will be no accidents in the process of showing us living samples of alien creatures."


    "Which do you prefer, major?" Vassily looked at the talking officer and recognized his rank.


    "I''m afraid it''s the latter kind, as you think." the major shook his head. He obviously had the same idea as Vasili: "the people of Yanguo didn''t ask us for help. It''s Lucia''s initiative to provide assistance. The official statement is to repay the people of Yanguo for their previous help to Lucia, that is, the people of Yanguo don''t need our assistance.


    But after we came, they didn''t leave us alone or throw us anywhere, so that we could kill some alien creatures in a decent way. Instead, they specially arranged experts to evaluate our equipment level. Now they decided to upgrade our equipment for us, and specially transported living samples of alien creatures to let us know more about the enemy, you What do you think they''re doing? "


    "I''m afraid that we are too weak and underestimate the enemy. If we go to the battlefield, we will be cannon fodder, which will directly destroy the whole battle, and even lead to the collapse of the front." although Vasili''s level and rank are not high, he still has read some military works. It''s not too difficult to understand this.


    "That''s right, that''s it." the major nodded. As an officer, he naturally knows more than a big soldier. How can Vassily not understand what Vassily can understand?


    When the officer said this, the expressions on Vasili and Chekov''s faces became a little ugly. Vasili was worried about their army, while Chekov was more or less unconvinced and wanted to prove that alien creatures were not so difficult to deal with.

 Chapter 689

    Chekov soon had the opportunity to prove himself. The people of Yanguo summoned all the lucians and introduced them in detail the known species and abilities of alien creatures in front of them. At the same time, they also showed them living samples of alien creatures.


    If Chekov really wants to prove his ability, he will stand up and ask to compete with alien creatures at this time. Although he will be punished and imprisoned afterwards, this is really a good opportunity to prove that human beings can defeat alien creatures.


    But when we saw that Yanguo people directly took a pistol equipped by Lucia''s army and directly emptied a magazine against alien creatures across the cage, and the alien creatures were unharmed, even if Chekov drank too much and dared to fight with the bear, he couldn''t help counselling.


    Although he is usually reckless, it is not to say that his brain is full of muscles and he can''t distinguish the difference in combat effectiveness.


    Although the power of the pistol is not high, it is too outrageous to shoot at close range and even break through the shell of a creature.


    Even if there are elephants and rhinoceros among the thick skinned animals on the earth, which can resist small caliber pistol shooting by rough skin and thick meat, it is not that the bullets can''t even hit a pit, or even bounce.


    Chekov himself has used the military pistol. He has a deep understanding of the power. Even if he shoots the steel plate, there should be a depression. Now the shell of alien creatures is directly resistant like steel plate, which is a little scary.


    Moreover, after comparing alien creatures with his own body shape, Chekov also lost the idea of melee combat with alien creatures, but he didn''t think that alien creatures were invincible.


    "Vasili, do you think you can kill aliens if you shoot at close range with bazuka?" Chekov whispered to his friends, still the somewhat irrelevant idea he had put forward before.


    But this time, Vasili was really considering his statement. After thinking about it carefully, Vasili said: "it''s no problem to use bazooka bazooka, but you just heard from the people of Yanguo that alien creatures appear like a tide. How many bazooka do you think you need to defeat them?"


    Bazuka bazooka can certainly kill alien creatures, which has been proved by Chinese people on the battlefield, but they also don''t think that equipping all soldiers with a bazooka is a way to defeat alien creatures.


    This is not to say that rocket launchers cannot destroy alien creatures, but they are not worth the cost of war and are not efficient enough.


    To take the simplest example, the rocket launcher was originally invented to fight tanks. It is undoubtedly very profitable for a rocket to kill a tank.


    However, if you use rocket launchers to fight infantry, one rocket can kill one class, which is still a loss in the war, because it theoretically takes only one shuttle bullet to kill one class.


    Of course, this is certainly not the case in actual wars. Sometimes it is worth paying even the greatest price in order to win a strategic place.


    However, in the battle with alien creatures, humans must calculate the cost.


    For alien creatures, although the lower level daughter of combat daughter will not be reduced to the status of bullet, it is not much better. It is just cannon fodder and consumables on the battlefield. It is an extremely cheap thing.


    As just said, it is profitable to destroy a tank with a rocket, but it is undoubtedly a loss to destroy only one infantry.


    Especially when alien creatures throw their lower daughters into the battlefield as bullet like consumables, it is not only very wasteful but also inefficient for you to use rockets to block them.


    After a rocket is launched, it needs to be loaded. At this time, the soldiers who launch the rocket have been torn up eight times by other alien creatures.


    Because of this, the military of Yanguo gave up the idea of using rocket propelled grenades, and instead equipped all infantry with exoskeletons and heavy machine guns that can break through the shell of alien creatures, and directly fired with heavy machine guns instead of naming names with rocket propelled grenades.


    In this exhibition, lucians clearly recognized the huge gap between themselves and alien creatures. At the same time, they also understood that equipping soldiers with armor piercing bullets and grenade launchers can indeed kill alien creatures, but they still can''t achieve the purpose of defeating each other. They can only die with dignity before being torn apart by alien creatures, Just a few cushions.


    But this is still a game that makes the battle loss ratio ugly.


    Human beings need at least 16 years to train a qualified soldier, so that the baby can grow from birth to the level of military service, and then spend a few months to a year or two to train.


    However, alien creatures can hatch new combat daughters in only a few months or even days or hours, and they are always in an endless stream.


    If so, humans simply do not have enough population to compete with alien creatures.


    This is also the reason why Yanguo accepts the reinforcements sent by lucians and plans to upgrade their equipment. One more country and one more soldier can at least spend more resources on the battlefield.


    Although this is very cruel or cruel, for war, an ordinary soldier is just a resource to be consumed, but generals need to decide where to consume it and how to make it meaningful.


    What the Yanguo military is doing now is to make these resources provided by Lucia not be wasted or consumed meaninglessly, but to give full play to their value and show the significance of their existence on the battlefield.


    "We don''t provide you with much equipment. After all, we don''t have enough equipment ourselves, so what we can provide you is a set of exoskeleton with jet backpack, but without armor plate. We will provide you with armor plate drawings. You can make your domestic production and transport it to you, although I don''t think there is a thin iron plate in front of alien creatures How much protective effect can it have? "Chen Xin is introducing the equipment provided to them to the senior management of Lucia''s army at this time.


    For the exoskeleton without armor plate, the senior management of Lucia''s army didn''t think there was any problem. After all, they also saw what alien creatures looked like. An extra layer of armor plate was nothing more than making alien creatures tear fresh-keeping film into packaging boxes, that''s all.


    "What about weapons?" these Lucia officers were more concerned about weapons than armor.


    Chen Xin held up a gun that looked very sci-fi on the table and said, "the trial type No. 2 electromagnetic rifle launches 9mm nail bullets in an electromagnetic orbit. Its penetration is no less than that of the traditional 12.7mm armor piercing bullet, which can cause effective killing to alien creatures."

 Chapter 690

    After receiving the equipment provided by Yanguo and knowing and getting familiar with the situation of alien creatures, the reinforcements sent by these lucians were finally pulled to the battlefield.


    Because the war situation was not very critical at this time, and the lucians also belonged to the friendly forces who came to reinforce, although the headquarters sent them to the battlefield, they did not directly put them into the front line to fight.


    Instead, it was placed behind the line of defense as a reinforcement force for auxiliary operations to familiarize them with the battlefield first.


    Although lucians don''t mind being thrown into the battlefield directly, since they can get familiar with the environment first, they naturally won''t have any objection.


    The lucians who arrived at the defense line were surprised by the fierce exchange of fire on the defense line at the beginning, and many people even felt frightened.


    They are not recruits, nor have they never experienced war. Some people even participated in the previous battle to suppress the opposition in the capital of Lucia, but they have not felt such a fierce battlefield.


    The dense sound of machine guns never stopped. It sounded as fierce as a rainstorm. The artillery and air strikes launched from time to time in the rear made them feel like they were staying in the trenches of World War II.


    However, this is only a daily battle on the defense line, not a real fierce battle at all.


    "What? Is this just an ordinary exchange of fire?" Chekov couldn''t help staring at the information introduced by a soldier of the inflammatory country.


    Vasili was also very surprised. He thought the soldier of the burning country who knew Russian asked, "but according to the density of your exchange of fire, this is a full-scale exchange of fire? We didn''t see such a fierce fight in the Middle East."


    "It''s different. The kind of war in the Middle East, even if the exchange of fire is fierce, is nothing more than the exchange of fire between several troops, but here, everyone on the whole line of defense is firing." the soldiers of Yanguo smiled at them and didn''t feel that lucians were making a fuss.


    In fact, he would be as surprised as these lucians if he hadn''t adapted to the fierce fighting in the defense.


    After all, the battle ahead is really fierce. Everyone on the whole defense line is shooting with weapons all the time, because if they don''t do so, the alien creatures who have been attacking the defense line like the tide will be submerged by their huge number.


    "What is the fierce exchange of fire like?" Chekov asked curiously, and Vasili was also interested in this question.


    The soldiers of Yanguo still smiled and said, "we threw 30 tactical nuclear bombs before."


    The two lucians suddenly widened their eyes and forgot to close their mouths.


    The suvians were really crazy about the use of nuclear bombs. They built reservoirs, railways and put out fires with nuclear bombs... Suvians did everything they could think of to use nuclear bombs.


    As the successor of suvia, Lucia is naturally familiar with nuclear bombs, but this does not mean that two Lucia soldiers have seen nuclear bombs used.


    In fact, in human history, there are still only two nuclear bombs that were really used in war.


    Although the soldiers of Yanguo are talking about tactical nuclear bombs, even tactical nuclear bombs are also nuclear bombs, and the number of 30 is already very terrible.


    This also made the two Lucian soldiers clearly understand what the battlefield against alien creatures was like, and how fierce the war was.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While the lucians adapted to the battlefield, Chen Xin was debugging a new model of Titan.


    "Academician Chen, is this the new Titan? How does it look different from the previous one!"


    Hearing that Chen Xin was going to test the new model of Titan, the military also quickly sent people to the scene to observe and understand the situation.


    But what appeared in front of them was a body with a great shape difference from the previous Titan, which surprised the military.


    "It''s really different. I modified a lot of designs. This one is prepared for large-scale mass production. Originally, some components on Titan that consume resources and man hours can be saved." Chen Xin explained to the military. He did omit and modify a lot of things on the new model of Titan.


    When Chen Xin said this, the people in the military nodded to understand. After all, the Titan was easy to use, but the cost was there. Even if Chen Xin increased the production line, the output was still so much.


    Because it is a test, there is still a previous universal model next to the new Titan. The comparison between the two is obvious, and people can clearly see the difference.


    The general-purpose Titan has a more human appearance, has two arms to operate weapons, is taller and has thicker armor.


    The new model of Titan makes people look slim and thin at a glance, and basically has no human shape.


    On the new model of Titan, Chen Xin adopted the anti joint motion structure to strengthen the walking ability, but cut off his hands and directly connected the weapons to the Titan''s body.


    In addition, Chen Xin directly transformed the Titan''s body into a weapon platform. The shape looked like a bowl buckled upside down. The trunk structure became much lower. Needless to say, the head also became installed in front of the body rather than directly above it.


    This makes the new Titan look like a hunchback with a turtle shell, arms loaded with weapons, legs walking against joints, and the shape looks quite strange.


    Although this design looks a little strange, after abandoning the human structure, the structure of the new model Titan is relatively simpler, and its production and operation have become a lot simpler.


    The military has no problem with the appearance. They are more concerned about the performance.


    However, there is no need to worry about this. Compared with the original universal Titan, the new Titan is definitely much better than the universal Titan in weapons.


    First of all, Chen Xin installed a dense array on the head of the new Titan like a turtle shell, while one side of his arms was a 75mm portable short barrel gun that had been verified on the general-purpose Titan.


    But this time he directly connected the gun body to the Titan, not the original portable.


    On the other side is a large caliber six unit aircraft gun, which is fed by a bullet chain, and the long bullet chain is connected to the ammunition box on the back of Titan.


    Watching the new Titan test the weapons it installed, the military was very satisfied with the firepower, but they still asked Chen Xin a question: "academician Chen, the speed and quantity of alien creatures are so fast and so many. In case they break through the firepower blockade and get close to Titan, how can they solve the problem of close combat?"

 Chapter 691

    If it were in the past, the military would certainly not consider the issue of close combat.


    Human beings have been separated from the era of cold weapons for hundreds of years, and melee in war has been a matter of decades ago. With the development of science and technology, human beings have been more and more separated from face-to-face combat in war, but attack outside sight.


    Even in close sight combat, the use of weapons such as guns and artillery is enough to kill the enemy when he approaches.


    In the past, the military used pistols to solve this problem. Soldiers were equipped with an assault rifle as the main weapon. When the enemy approached, they used pistols to fight at close range.


    After all, in modern warfare, no one will equip ordinary soldiers with protective equipment such as bulletproof vests or armor. The penetration of pistols is enough to kill the enemy in front of them.


    However, as the battle between humans and alien creatures unfolds, small caliber weapons are just a scratch on the surface of alien creatures, and even the skin can''t be broken, so they have become useless.


    What this leads to is the overwhelming disadvantage of mankind in the close combat between humans and alien creatures.


    Although relying on weapons with large caliber firepower, humans can still kill alien creatures at close range, once alien creatures attack humans, ordinary soldiers are simply unable to resist.


    The jet backpack developed by Chen Xin has solved some of the above problems, giving ordinary soldiers at least one chance to widen the distance in close combat.


    But this is only a temporary cure, not a permanent cure.


    This is especially true for large vehicles such as Titan. After all, it is impossible for Titan to fly.


    Even if Chen Xin can do it, the cost is still a big problem. With the technology and resources to make Titan fly, doing something else can change the war situation.


    So the Titans had to think about melee.


    Before, it was easy to say that the general-purpose Titan could solve the problem of close combat by adding bayonets to the weapons equipped, or simply bringing a cold weapon like Chen Xin''s white dragon.


    Even if these bayonets and cold weapons play a self-defense role and don''t die so miserably, they do solve the problem to a certain extent.


    At least, in case of emergencies, you can draw a knife to decide life and death, rather than lead the neck to kill.


    However, the new model of Titan needs to face this problem. It has removed its arms and replaced them with weapons, which has indeed saved a lot of resources, reduced unnecessary structures, and made maintenance and production much more convenient.


    But similarly, if you lose the grip ability of both hands, you can''t equip melee weapons.


    In the past, infantry can be used to solve this problem. In any case, infantry and tanks cooperate, tanks cooperate, and Titans cooperate as well.


    But now... If alien creatures break through in front of them, the Titans can''t stop the attack, and ordinary soldiers can only be regarded as an addition, which can''t play a big role.


    Of course, Chen Xin had already prepared and considered this. He motioned to the staff on one side that they would push out the melee weapons specially prepared for the new Titan after receiving Chen Xin''s signal.


    It''s a large chain saw the size of Titan.


    "When designing the new Titan, I also considered the need to replace weapons to deal with different tasks. Therefore, the new Titan''s arms are plug-in. When it needs to be replaced, it only needs to pull out the originally installed weapons to replace them." Chen Xin commanded the staff to replace the weapons of the test body, While explaining to some stunned military representatives, "this is also for the convenience of logistics maintenance. If the weapon is broken but the body is still intact, the combat effectiveness can be restored by replacing the weapon.


    The melee problem you are worried about is also simple. You can solve this problem by replacing one hand with a melee weapon.


    However, I generally don''t recommend this, because it will weaken the firepower.


    Of course, this is just a suggestion. How to configure weapons is your military''s business. I won''t do much. "


    "What did academician Chen say? The design of the new Titan is very good. Thanks to academician Chen, we can have such new equipment!" the military representative said sincere compliments to Chen Xin, but did not forget to ask: "Academician Chen, what are the production costs and man hours of the new model Titan? If the existing production line changes production, how long will it take to adjust? What changes should be made in the process?"


    These are really key issues. Whether a piece of equipment is easy to use depends on whether it is large enough. No matter how easy it is, it can only be built one or two. Unless it is a nuclear bomb that can solve the problem, it will be useless.


    "At this point, please rest assured that the production cost of the new model Titan is one third lower than that of the general model. The parts adopt a simpler design, which makes it easier to produce, and the technical threshold is correspondingly reduced. More factories can produce these parts." Chen Xin took the military representative to the new model Titan and continued to introduce: "Because the structure is simplified and the modular design is adopted, the maintenance is also much simpler.


    If you have enough parts, you can use spare parts to put together one in a day in the rear maintenance station, even if you only rely on manpower. "


    "Can you use human parts to make one in the maintenance station?" the military representative was completely surprised. Although he understood from Chen Xin''s introduction that the structure of the new model Titan is simple and easy to maintain, he didn''t think it could reach this level.


    It''s like someone telling you that there are enough parts to put together a car for you in the garage. It''s beyond the scope of normal imagination.


    "It''s OK in theory, but under normal circumstances, key parts, such as engines and airborne main engines, will not be prepared at the maintenance station. The damage of these parts can only be repaired by returning to the rear repair shop." Chen Xin explained to the military representative.


    Although the modular design makes maintenance easier, it is obviously impossible for Chen Xin to really make a Titan in the field repair station in front of him.


    After all, even if he reduces the production difficulty and cost of parts, the key core parts are still quite sophisticated things, which cannot be placed in the repair station in front for simple battlefield maintenance.


    Military representatives can also understand this kind of thing. After all, the battlefield simple repair station in front only plays the role of maintaining and repairing some minor problems. It is impossible to really play the role of overhaul. In that case, the maintenance cost of the repair station is too high.

 Chapter 692

    Holding the electromagnetic rifle in their hands, they kept shooting the bullets in the drum at the alien creature in front. Vasili and Chekov had adapted to the high-intensity battlefield and even had leisure to chat in this fierce battle.


    "Vasili, how many bullets do you have left?" Chekov felt a sudden meal in his electromagnetic rifle, skillfully took out a new drum from his ammunition hanger, replaced it, and continued to pull the trigger, which asked Vasili aside.


    Vasili was covering Chekov who changed his bullets at this time. Seeing that he had changed his bullets, he checked his residual ammunition and said, "I still have four drums. Save some use, man. We have to stay here for two hours."


    "I know, but this bullet can last up to half an hour." Chekov estimated the consumption of ammunition and thought they might not last that long.


    Although it was a defensive operation and the shooting was almost non-stop, they subconsciously saved bullets, rather than holding the trigger and soon emptied the ammunition they brought, and had to go to the rear to replenish ammunition.


    It is reasonable to say that both of them are veterans and should not make such mistakes that are difficult for recruits to make on the battlefield for the first time.


    Even if the recruits are too nervous, they can empty one magazine at most, not all their bullets.


    But for Vasili and Chekov, they were put into the front line for the first time. When facing the tide of alien creatures, tension and pressure made them unconsciously consume ammunition quickly.


    However, even if the drum with a capacity of 100 rounds is empty, it can not make the monsters in front of them less, which undoubtedly makes them bear a great mental impact and pressure. It is not uncommon to empty all ammunition.


    Even for veterans who have experienced many battles, in the face of enemies that can''t be killed, or monsters with terrible shapes such as alien creatures, it''s not impossible to have a mental breakdown, let alone empty ammunition.


    The problem would have been even more serious had the military not anticipated such a situation at the beginning and allowed them to adapt to the battlefield in advance.


    But even so, many people had mental problems when the reinforced Lucia army was officially put into the front line of the defense line for the first time.


    This caught Lucia''s military by surprise. Although they were ready to face the terrible enemy and deal with all kinds of problems before coming, they were still in a hurry because of the large number of non combat attrition in the first battle.


    After all, this is the first time for Lucia.


    As an old army power, lucians were not so ashamed even if they participated in two world wars in the suvian era.


    When such a thing happened, Lucia''s military could only send the soldiers with problems to treatment, and rectify the remaining soldiers so that they could adjust their state and deal with the battlefield.


    They came as reinforcements. It is undoubtedly unacceptable that they lost their combat effectiveness before they fought much.


    Fortunately, the lucians are the existence of the so-called fighting nation. After some rectification and adjustment, their army has regained its combat effectiveness and put into the battlefield again.


    The lucians who once again entered the battlefield performed much better this time. Although some people were still very nervous, at least they could stably hold the defense line and play their due combat effectiveness.


    "The lucians have performed well recently. It seems that they have adapted to the battlefield." in the headquarters, the general is satisfied with the state of the lucians and praised them. At the same time, he also informed Chen Xin: "they plan to send another group of troops from home. It seems that the previous performance is too poor, which makes the senior level of Lucia feel very ashamed."


    "Let soldiers risk their lives on the battlefield because of losing face? I don''t quite understand this idea." Chen Xin shrugged and didn''t care much about it. Although it was all human life, since Lucia''s senior management thought it was worth saving face with human life, he was eager to use more battlefield fillers to reduce the casualties of his own soldiers.


    "Soldiers defend the country. If they lose face at this time, they have to earn it back hard, otherwise it will be a shame for a lifetime." the general understood a little, said a word to Chen Xin, and asked, "how are the new Titans ready? Can they be put into use now?"


    Hearing the general''s question, Chen Xin was also serious. He organized some language before answering: "at present, the design work has been basically completed, the model has been determined, and several prototypes have been tested. However, I still want to put them into the battlefield for actual combat test, and then let the factory produce."


    "Actual combat test? Academician Chen, do you think there are still problems with the new Titan?" the general didn''t understand the design, but when he heard Chen Xin say so, he asked with concern.


    "It''s not a problem, but to determine whether there are any deficiencies through actual combat test, or to check whether it can give full play to its combat effectiveness on the battlefield and achieve my expected results." Chen Xin explained.


    Although the general didn''t quite understand Chen Xin''s practice, he nodded and said, "since academician Chen, you need actual combat tests, I''ll arrange it. When can you put them into the battlefield?"


    "As soon as possible, for the new model of Titan, we have built a total of five prototypes. Find an area where the war is not very fierce, and organize the five prototypes into a team to be responsible for battlefield support." Chen Xin thought and explained the situation to the general.


    He wanted to put these Titans into the front line to directly participate in the battle, but this is a new equipment, which has not been tested in the actual battle. So he put them into the front line. In case of any problem, the body loss is small, and in case of loose defense line, it is a big problem.


    So even if he plans to test the new model of Titan in actual combat, Chen Xin still decides to be safe and conservative.


    Hearing what Chen Xin said, the general nodded clearly and replied: "In that case, let the new Titan invest in the defense line stationed by the lucians. Originally, this is not the main battlefield. It is important for the lucians to garrison here. The war situation here is not very fierce. It is just right to test the new Titan. Even if there are any problems, we can respond in time."

 Chapter 693

    Jiang Juan is a female soldier and a rare female car soldier.


    Before the disaster, based on the idea of training herself, she signed up for the army after graduating from college, and then obeyed the assignment and became a car soldier.


    This is not very common in the military. Although the military also recruits women soldiers in many arms in accordance with the principle of equality between men and women, there is still a certain gap in the number of women soldiers compared with men.


    This has led to the rare presence of female Autobots in the army.


    Originally, Jiang Juan could retire from the army after military service and live an ordinary life again, but when the disaster came, everyone''s retirement time was postponed indefinitely, which led to her staying in the army.


    Later, the military selected Titan drivers. Although auto soldiers such as Jiang Juan were not the first priority, they were also within the scope of selection.


    Jiang Juan was also very lucky to pass the screening and became, although not the first batch of Titan reserve drivers.


    However, because Titan always has more drivers than the body, Jiang Juan has been trained in Titan driver training base before, and occasionally she can get a chance to actually drive.


    In her opinion, as long as the country continues to produce new Titans and she tries to improve her driving skills, it will always be her turn to become a formal driver and have her own body.


    However, this opportunity came much faster than Jiang Juan expected and much more than she expected.


    The invasion of alien creatures put all Titans into the front line, and the factories in the rear are working overtime to produce new bodies. Their reserve pilots, who can operate the bodies on the battlefield, were stuffed into the newly created Titans and sent to the battlefield.


    Under such circumstances, Jiang Juan sat on the Titan she had been thinking about, and then drove it to the battlefield.


    The intensity of the war exceeded Jiang Juan''s imagination. Even the solid and reliable Titan in her view would also be destroyed by alien creatures.


    Originally, with her hard-working driving skills, Jiang Juan''s body was also damaged, but basically it was a small injury that could be repaired without losing the precious Titan.


    Unfortunately, in the previous war centered on Honghu area, Jiang Juan''s Titan was attacked by the capsule, the front armor was eroded, the Titan''s engine was damaged, and the nuclear battery package was damaged, resulting in radiation leakage.


    Although Jiang Juan made great efforts to drive her back to the rear maintenance point, the excessive radiation value still made the ground service technician of the maintenance point announce that the body can not be repaired and can only be recycled.


    Jiang Juan, who lost her seat, was also sent to the rear to wait for a new body.


    This made Jiang Juan very depressed for a time. Although it was normal for such things to happen in the war, the body she liked very much was lost in less than a month, which still made Jiang Juan feel that she had made an unforgivable mistake.


    She clearly knows how valuable a Titan is. Otherwise, she would not have driven the body back to the rear at the risk of excessive radiation after the Titan''s nuclear battery package was damaged, hoping to be repaired.


    However, the body leaked excessive radiation and the engine was damaged. Obviously, her beloved seat has lost the value of maintenance and rescue. She can only disassemble the useful parts and send the rest to the rear for recycling.


    This made Jiang Juan once fall into self blame and regret. She even began to doubt whether she was really qualified to drive Titan.


    However, during the war, there was no time for her to doubt and deny herself. After the new Titan was produced, she was assigned to a new body again and returned to the battlefield.


    But this time, what she belongs to is not the familiar universal model, but the new model that Chen Xin plans to carry out practical test. At present, it is a new Titan named Gongshi Titan.


    Compared with the general type familiar to Jiang Juan, the Gongshi Titan is obviously much simpler in structure and driving.


    But after being familiar with the body, Jiang Juan found that although the structure of the body is much simpler, the firepower of the body has been greatly strengthened.


    The whole machine body has three weapon slots, all of which are modular design, and can be replaced with different weapons at the maintenance point at any time, which makes Jiang Juan very satisfied.


    The previous general-purpose model used a hand-held design. Although weapons can be changed quickly, it is difficult for the general-purpose model to hold both hands and let the two weapons fire together because it is hand-held.


    However, the Gongshi type has obviously strengthened in this regard. Including the overhead weapon position, the weapons installed in the three weapon positions can fire at the same time, which greatly enhances the firepower output intensity in unit time.


    This undoubtedly makes Jiang Juan and other drivers feel very satisfied. After all, although the previous general-purpose weapons have strong firepower, they are still a grade worse than the Gongshi type.


    In particular, Jiang Juan was satisfied that the weapon types of the three weapon positions were not fixed, but could be selected by the driver according to different tasks.


    Due to the experience that the body was destroyed by baopaozi last time, Jiang Juan did not replace the dense array on her head. In her opinion, this thing can effectively protect the body from the attack of baopaozi.


    After all, this thing is used to hit missiles. Even if the firing speed is reduced, it is still no problem to hit those flying vesicles. Even if it means carrying more ammunition boxes and increasing the body load, it is worth it in Jiang Juan''s opinion.


    As for the weapon position of both hands, Jiang Juan chose a six barrel machine gun to shoot alien creatures, while the other hand was equipped with a new melee equipment chainsaw sword that she had never seen before.


    According to Jiang Juan''s previous combat experience, the killing effect of the 75mm short barrel gun equipped by Titan is not very good. If it is really more efficient than killing, the effect of machine gun is the best.


    As for the chainsaw sword, Jiang Juan intended to use it to deal with close combat. Before that, the body of her comrades in arms was demolished by the combat daughter rushed to the front.


    Therefore, in order to resist the possible melee, Jiang Juan specially chose this chainsaw sword.


    Although not everyone of the other four bodies with her chose chainsaw sword, they were basically the same in the choice of other weapons.


    Everyone gave up heavy firepower such as short barrel guns and chose more efficient rapid fire weapons such as machine guns and machine guns.


    After completing the selection of weapons and equipment and ammunition supply, the five new male Titans were sent to the battlefield.

 Chapter 694

    Exoskeleton, power armor, electromagnetic rifle, Titan


    Watching Yanguo people constantly take out all kinds of awesome sci-fi painting style equipment from their crotch, lucians feel that they have been left behind for a whole era.


    "Vasili, how do you think the Yanguo people made these powerful guys? Compared with them, I feel like we still stay in World War II and use the mosinagan of my grandfather''s generation!" Chekov complained to his friends and looked at the male Titan spitting fire and death, full of envy.


    Vasili was also envious, and not just him. In fact, all lucians were very hot about the equipment of the army of the burning country.


    Before the disaster, the two countries had many joint military exercises. In fact, Lucia''s military was also familiar with the military equipment of the Chinese people.


    But now it seems that after a disaster, the people of Yanguo have begun to list and install all kinds of science fiction equipment, while the lucians are a century behind, as if they were still in the era of World War II.


    In particular, they are facing alien creatures, which makes lucians feel as if they have been thrown into the shooting scene of a science fiction blockbuster.


    All the soldiers at the bottom are full of envy for the military equipment of Yanguo, but this envy has no negative impact. After all, they have also obtained the weapon upgrade of exoskeleton and electromagnetic rifle from Yanguo.


    After experiencing the satisfaction brought by high-tech weapons, the soldiers at the bottom did not have any negative emotions because of this kind of thing.


    However, senior officers are very worried about this. Yanguo is a neighbor of Lucia. Now Yanguo''s military equipment has completely crushed Lucia, which makes these officers worry that their military equipment lags behind their neighbors.


    Although the two countries are now allies and are jointly fighting against alien creatures, Yanguo has never shown aggression against Lucia, which can not reassure the officers of Lucia.


    After all, it is impossible for a country''s national defense and security to rely on the kindness of its powerful neighbor, even if the neighbor is really kind.


    Therefore, after people collected and sorted out the data of these military equipment now put into the battlefield in Yanguo, Lucia''s officers sent these data back to China, so that China could find ways to develop the same equipment, or find ways to obtain technical support from Yanguo, so that they could produce such advanced equipment themselves.


    Lucia''s senior management naturally attached great importance to this. In fact, they had discovered this problem as early as when Yanguo sent people to assist Lucia''s capital. After all, at that time, Yanguo people had made exoskeletons, power armor and Titans, which can be called black technology, shine in front of lucians.


    However, at that time, Lucia was on the verge of collapse. The senior management of Lucia needed to deal with various livelihood issues first, so that the country could be maintained and continued, and did not have much energy and resources to invest in the research and development of new equipment.


    In particular, Lucia''s own scientific research ability has declined sharply in recent years. Many advanced military equipment even rely on archaeological methods to dig data from the archives of the past Soviet era in order to resume production, which really makes Lucia, once one of the world''s poles, feel very ironic.


    For this reason, after people''s livelihood was restored, Lucia''s senior management paid attention to scientific and technological research and development, and asked domestic scientific research institutions to improve their own science and technology.


    We should not exaggerate like Yanguo, but at least we should ensure the production and life of our people.


    After receiving the information and requirements from the military, the senior management of Lucia naturally transferred these information and requirements to the relevant scientific research departments.


    However, Lucia''s scientific research department can only say that it is powerless.


    Exoskeleton, electromagnetic rifle, power armor and even Titan are not impossible to do with Lucia''s domestic technical strength, but they can''t solve the energy problem.


    Obviously, not every country can be like Yanguo. Some people hang up to help solve problems. If ordinary scientists want to make a breakthrough, they can''t have results in a short time.


    After receiving the feedback from the scientific research department, Lucia officials did not give up the idea of independent research and development, but also had to seek technical cooperation from Yanguo.


    Although the high level of the country was not happy with its success, it did not refuse the technical cooperation request of the lucians.


    After all, the current environment is such that it is better to have an ally who can cooperate and help each other than to fight all problems alone or simply have one more enemy.


    Only when Lucia got the consent of Yanguo and prepared to set up a scientific research team to conduct technical exchanges with Yanguo, Chen Xin, as one of the most key figures, was unable to take the time to take charge of it.


    Because at this time, he is working with biologists to study the abnormal offensive setback of alien creatures during the previous nuclear explosion.


    "I think we should find inspiration from electromagnetic interference. Now that we have determined that the connection between alien organisms depends on electromagnetic waves, we can take this as a breakthrough and use electromagnetic interference equipment to interfere with alien organisms and affect their command." a biologist put forward his own view according to their existing research results.


    After listening to the biologist, Chen Xin did not object to this.


    Based on the information currently obtained and the clues they have at hand, Chen Xin also feels that the previous setback in the alien biological offensive is largely due to the EMP impact caused by the nuclear explosion affecting the command link of alien organisms and interfering with their command.


    "But we have done experiments. Electromagnetic pulse has no effect on alien organisms!" another biologist questioned.


    One of the important effects of nuclear explosion is EMP impact. Obviously, they will not let go of such obvious information. Moreover, when alien creatures are dissected for the first time, it is proved that they communicate with each other by electromagnetic signals, which makes them think of this first.


    However, it is strange that they have conducted many experiments, whether using living biological samples held in the laboratory or directly on the battlefield, which have not had an impact on alien organisms.


    Because of this, biologists give up this idea and look for other possibilities.


    However, after many experiments, they still have to turn their eyes back to the idea of electromagnetic interference.


    Because other attempts have failed, only electromagnetic interference is the most likely in all possible hearts.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 695

    "Can it be that the intensity of electromagnetic interference is not enough? The EMP impact intensity produced by nuclear explosion is very high. It seems that the electromagnetic interference test we did did did not reach that high intensity. Is this the reason?" some people put forward different views and tried to find the details they did not notice.


    However, Chen Xin shook his head and denied this possibility: "it should not be a strength problem. When we do experiments in the laboratory, the strength may not be enough, but when we test on the battlefield, we use military jamming equipment, and the jamming strength is no less than a nuclear explosion."


    "What''s the reason? Is it the interference frequency? But we use all channel blocking, so there should be no problem!" another researcher with military background asked suspiciously.


    "There must be something we haven''t noticed. There is no doubt that the idea of electromagnetic interference is correct, but it is obvious that the communication mode of alien organisms can not be interfered simply by electromagnetic wave interference or full channel blocking." Chen Xin secretly hates that he is not a real expert at this time, and he has no inspiration in his mind.


    Biologists in a room can''t find inspiration. After all, they usually study organisms, not electromagnetic waves.


    At this time, someone suggested, "we don''t have the right major. Why don''t we find some people in communication and physics to help analyze?"


    "Yes, I''ll apply to the above." when Chen Xin heard the proposal, he nodded and agreed. At the same time, he saw that all his faces were hard to hide their fatigue, so he said, "everyone has worked hard. Let''s stop here today and go back and have a good rest."


    Chen Xin said that the biologists in the laboratory had to stop their work and left the laboratory in twos and threes. The rest were sorting out their work at hand and planned to leave after finishing it.


    Seeing that everyone went to rest, Chen Xin also sorted out the things on hand. After sorting them out, he planned to leave the laboratory to eat.


    During this time, he also spent a lot of time in the laboratory. Sometimes he didn''t care about eating at all. When he was hungry, he sent the staff to get something to eat. Filling his stomach indiscriminately was even a meal.


    Now he decides to have a rest. Chen Xin can''t stand hunger. He wants to go to the canteen and have a good meal.


    However, when he left the laboratory, he found that Mo Qingyan was waiting at the door of the laboratory with a food box.


    "Ah Xin, are you hungry? I brought you something to eat." seeing Chen Xin coming out, Mo Qingyan quickly greeted him and raised the food box in her hand.


    "Why are you here? Have you been waiting for a long time?" Chen Xin quickly glanced at his watch and found that it was already time for dinner. He asked Mo Qingyan painfully: "why don''t you go in? Just stand here."


    "I was going to go in, but when I saw you discussing things, I was afraid to disturb you, so I waited outside." Mo Qingyan shook her head slightly and didn''t think it had anything to do with waiting: "don''t say that. You must be hungry. Eat first!"


    Then he handed the food box in his hand to Chen Xin.


    Chen Xin took the lunch box and was slightly moved, so he said to Mo Qingyan, "go to my office."


    They came to Chen Xin''s office and sat down at his desk. Chen Xin opened the food box and looked at the hot food inside. Without being too polite, he directly picked up chopsticks and ate.


    Looking at Chen Xin''s wolfing down, Mo Qingyan couldn''t help laughing and said, "slow down, and no one will rob you."


    "I haven''t eaten much since the morning and patronized the research." Chen Xin replied and took two more mouthfuls of rice. Suddenly, his face changed. He pointed to the water cup on one side and blushed at Mo Qingyan and shouted, "water! Water!"


    Mo Qingyan quickly picked up the water cup and handed it to him. She went to him, patted him on the back and said painfully, "slow down!"


    "It''s okay to choke at once." Chen Xin replied and put down his water cup. Then he continued to eat, but his action did slow down a little.


    Seeing that Chen Xin was all right, Mo Qingyan sat down again. Looking at his face with black circles under her eyes, she lost a lot of weight. She couldn''t help asking painfully, "ah Xin, are you working very hard recently? You work overtime every day these days, and your uncles and aunts are worried about you!"


    "There''s no way. We''re at war now! We''ve worked out the results one day earlier, so the front line can sacrifice less people. How can we have time to rest!" Chen Xin shook his head helplessly.


    It''s a time of war. Everyone is working hard for the war against time. He really has no reason to relax and rest.


    If I hadn''t seen you today, I would have been too tired. Chen Xin wouldn''t have said to let you have a rest.


    But for Mo Qingyan, it is no doubt that she can not be satisfied. She is very distressed and unhappy and said, "but even if you work hard, you should still pay attention to your health! What if you are tired?"


    "No, I''m measured, and I''m the person in charge. I can''t rest. Let others still work? What''s that like!" Chen Xin smiled.


    In the past, he was also a good fisherman, but now he has experienced so much and assumed so many responsibilities. Coupled with the impact of the war, he has gradually changed his character and style of action and become more serious and responsible.


    Mo Qingyan has become speechless by Chen Xin''s words. After all, she can''t say anything to let Chen Xin rest and others continue to work.


    Finally, she can only reluctantly advise Chen Xin: "then you should have a good rest and eat on time! Look at you, people are tired and thin."


    "I see! I promise you I''ll have a good meal and have a good rest." Chen Xin assured Mo Qingyan, half caring and half changing the topic: "By the way, I haven''t been home for such a long time. What''s the situation at home? After moving to the Dome City, everything at home is Qing Yan. You''re busy. Ah LAN went to the battlefield and I have to work. My parents rely on you to take care of them. It''s really hard for you!"


    "Nothing, that''s what I should do." although knowing that Chen Xin was changing the topic and that most of his promises were just comforting words, Mo Qingyan didn''t say anything, but comforted him: "Don''t worry, everything is fine at home. After all, your identity is here. There''s nothing difficult and need to worry about. My uncles and aunts are in good health. I don''t need to do anything. They are worried about you and let you take good care of yourself."


    "Hard work!" Chen Xinxin felt guilty and couldn''t help holding Mo Qingyan''s hand.

 Chapter 696

    With Chen Xin''s application, the senior management soon coordinated several communication experts and electromagnetic physicists to assist in the research.


    With physicists and communication experts, research will soon resume. However, this time, Chen Xin handed over the research on how to interfere with alien biological communication to a new research team composed of physicists and communication experts, while biologists re focused their research on alien organisms themselves.


    Chen Xin put down his scientific research work and started mass production of the new model Gongshi Titan instead.


    Before, five male Titans were put into the battlefield for actual combat test. The results obtained made the senior management very satisfied, and the mass production was naturally put on the agenda.


    Originally, this kind of thing should not be handled by Chen Xin, but as the chief designer of Gongshi Titan and the general person in charge of the project, although someone will handle the specific affairs on how to mass produce this new Titan, he still needs to overview everything and coordinate all aspects.


    The production plant of Gongshi Titan is still on the side of the Dome City, but instead of adjusting the production line of the original general-purpose Titan, another factory has been built.


    This is a new factory built when Titan decided to expand its production. It was originally intended to produce general-purpose Titan.


    However, as the Gongshi model has been designed in such a short time and is ready for finalization and mass production, the new factory originally scheduled to produce general-purpose model will naturally have to make corresponding adjustments.


    After all, the two models of Titan military have made a comparison and made the decision to use the main production capacity for mass production of Gongshi type.


    "Academician, the adjustment of the production line at the new factory has been basically completed, and the factory is going to be ready for trial operation. Do you see when you need to go?" a staff member found Chen Xin, handed the report submitted by the factory to Chen Xin and reported to him.


    Chen Xin nodded slightly. After turning over the report, he replied positively: "trial operation is very important. Let them determine the time. I''ll go there at that time."


    "Good academician, I will inform them to confirm the time." the staff nodded. He understood that Chen Xin''s time was very precious. Only when the factory determined the time of trial operation, Chen Xin could make corresponding schedule adjustment.


    "The production of the new Titan is very important. You let the factory keep an eye on it. There can be no mistakes in all aspects. If there are any problems, let them report them directly and I''ll solve them. We can''t delay the production." Chen Xin told us not to worry.


    "Academician, don''t worry, we''ll handle it." the staff nodded and wrote down Chen Xin''s words, but it seemed that Chen Xin''s words reminded him of something, so he opened his mouth and asked Chen Xin: "Academician, when the five Gongshi models were tested in actual combat, some drivers reported that the Gongshi model''s firepower could be strengthened. However, at that time, it was mainly to test whether the Gongshi model met the design requirements, so this matter was not reported, but recorded. What do you think should be done?"


    "Hmm? The pilot said the firepower could be improved?" Chen Xin showed a surprised expression.


    The warrior Titan was designed by him, and all equipment was tested in actual combat.


    Under such circumstances, the pilot said that he could increase his firepower, which inevitably made Chen Xin feel a little strange. He wanted to know how the pilot planned to increase his firepower.


    "That''s what the driver said at that time, but he only mentioned it at that time. The on-site maintenance technicians didn''t ask more about the specific situation, and the driver didn''t say more." the staff recalled the situation and explained to Chen Xin.


    Chen Xin nodded slightly. It was normal. The driver probably just felt it at that time. The staff wrote it down and didn''t go deep into the matter.


    After thinking about it, he said to the staff in front of him, "which driver is it? Let him sort out his ideas and write a report. If it is feasible, he will be rewarded."


    "It seems to be a female driver. She was the driver of Titan before, but she took turns to drive the new body after the plane was broken." the staff recalled it a little and soon recalled the driver''s information.


    "Female drivers? This is a little rare." Chen Xin was even more surprised.


    In fact, he has seen most Titan drivers, of which the proportion of women is quite small. When he was still in the scientific research center, there were only a few female drivers in the driver team of Titan driver training base except Qin LAN, and most of the others were men.


    However, this only surprised Chen Xin. He didn''t pay too much attention to this matter. He just said to the staff: "let her sort out her ideas into a report and hand it in as soon as possible."


    "Yes, academician." the staff answered and left Chen Xin''s office.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    In the maintenance station behind the defense line, maintenance technicians are repairing various vehicles and equipment parked here.


    Although it is a positional battle, the loss of various weapons, equipment and vehicles is still not small. Damaged or faulty equipment and vehicles are sent every day.


    This also led to the maintenance technicians working almost three shifts day and night, in order to repair these equipment and vehicles as soon as possible.


    Among all the weapons and vehicles, several titans are undoubtedly the most attractive and one of the most priority maintenance equipment for maintenance technicians.


    At this time, the Titans parked in this maintenance station do not need much maintenance. They are the five Gongshi models that were tested in actual combat before. Because they are all new bodies, there is no loss in the previous actual combat test. Parking here is just routine maintenance.


    Just next to one of the airframes, a maintenance technician is being pulled by the driver to say something. He looks very helpless.


    "But this can greatly improve the Titan''s firepower output. Connect the two machine guns in parallel and make them into a double assembly. In this way, you can output double firepower per unit time, which can greatly improve the Titan''s firepower! Master Wang, you are the best, so do me a favor!" the female pilot is Jiang Juan, She is begging the maintenance technician to help her transform her seat.


    "I said, little girl, I really can''t promise you what you said. If I don''t say that changing equipment in private is a punishment, I don''t mind carrying a punishment to help you transform, but where does this material and equipment come from? I can''t change a machine gun for you? And even if the organic gun gives you trouble, the conditions of this maintenance station can''t be transformed so much!" The maintenance technician looked at the female driver in front of him and looked very helpless.

 Chapter 697

    "The idea of double machine gun is indeed feasible, but it is not practical." after receiving the report from Jiang Juan, Chen Xin commented that it is not practical.


    "Academician, why don''t you think it''s practical? Isn''t the design of double machine gun able to double the fire delivery?" Jiang Juan, who was called to the office by Chen Xin, was a little unconvinced.


    The idea she put forward was based on her actual experience on the battlefield. It was directly denied by Chen Xin, which was obviously unacceptable to her.


    Chen Xin shook his head and asked her, "since you are a Titan pilot and have used machine guns... What machine guns do Gongshi use?"


    "The Gongshi gun is a 23-1 aircraft gun with a caliber of 23mm. It uses 23mm standard aircraft gun shells and is a single barrel sliding core machine gun." as a driver, Jiang Juan is very familiar with the Titan and supporting equipment she drives.


    Chen Xin nodded slightly and was very satisfied with her professional ability, so he then asked, "not to mention the technical difficulty of dual loading transformation, I just ask you, what is the spacing between the two muzzles, have you calculated?"


    "This..." Jiang Juan hesitated for a moment, but quickly replied loudly: "report, no!"


    "No more than 20 cm." Chen Xin announced the answer to Jiang Juan and explained: "I haven''t thought about the design of the dual mounted machine gun, or even there is no dual barrel machine gun that can be used, but in the end, we choose the single barrel machine gun, not because we can''t afford to use the dual barrel or don''t want to use the dual barrel machine gun, but because the double fire projection of the dual barrel machine gun can''t play a good effect on the battlefield compared with the single barrel machine gun."


    "Why? With one more barrel, you can hit one more shell and cause more damage?" asked Jiang Juan strangely.


    Chen Xin shook his head. Obviously, he was disappointed that Jiang Juan could ask such a question, but he still explained: "if it is used to hit targets such as aircraft or tanks, double the firepower delivery can really solve the problem, but the problem is that we are fighting alien creatures now.


    A 23mm general-purpose machine gun ammunition is enough to break through the shell of alien creatures and cause effective killing. One more shell is still hit in the same position to a large extent, which can not effectively improve the damage efficiency of alien creatures except blowing the target to pieces. "


    Adding a gun barrel can indeed increase the ammunition delivery, which can also improve the probability of effective killing when dealing with armored targets such as tanks and aircraft.


    After all, you can''t just hit a tank or a plane with one shell. One more shell can improve the possibility of hitting the target.


    However, when the target is replaced by an alien creature that can be killed by one shell, adding a gun barrel and doubling the ammunition delivery is just a waste of ammunition.


    The target that can be killed by one shot does not need two shots to kill. The two gun tubes are so close that the two shells will basically hit only one target. One shot can ensure the killing. The two shots only blow the target to pieces. There will be no such thing as two gun tubes can hit two different targets.


    In fact, the multi barrel machine gun is just a way to improve the firing speed when the machine gun firing speed was not enough in the past.


    However, for the modern military industry, it can achieve extremely high firing speed, and the ammunition delivery volume can even reach thousands of rounds in one minute. At this time, the multi barrel machine gun appears to be chicken ribs and impractical.


    This is also why there are fewer and fewer gun tubes on modern warships. Except for Gatling''s rotary tube design, there are few multi tube designs.


    Because with the support of modern science and technology, one barrel is enough to ensure sufficient firing speed and smash enough shells to the enemy.


    After listening to Chen Xin''s explanation, Jiang Juan was frustrated. Although she still felt a little unconvinced, she also knew that her ideas were not so practical.


    "But you don''t have to be depressed. Although it''s superfluous to be a double mounted machine gun, it doesn''t mean it has no reference value at all." Chen Xin comforted Jiang Juan.


    However, his words are not simply comforting, but they do have a certain reference value.


    "For alien biological warfare, we really need to increase the fire delivery." Chen Xinjian showed a puzzled look to Jiang Juan, so he explained to her: "simply increasing the firing speed or adding an additional gun barrel is meaningless, because doing so will only hit a large number of bombs and drugs on the same target, which is a very inefficient method for this war.


    What we really want is to hit more ammunition on the enemy''s head in unit time, but we also want to avoid putting too much ammunition on the same target.


    To achieve these two goals at the same time is the key for me to design the Gongshi type into three weapons, because in this way, the three weapons can project ammunition to three different targets at the same time, which can not only effectively improve the fire delivery volume, but also improve the killing efficiency. "


    "In that case, isn''t my idea meaningless?" Jiang Juan also understood Chen Xin''s idea at this time. He obviously didn''t want to waste a lot of ammunition on the same goal.


    "It really doesn''t mean much to Titans, but it has different meaning to ordinary weapons." for Jiang Juan''s idea, Chen Xin is not comforting her, but does have a certain reference value.


    "Ordinary weapons? Academician, do you mean individual weapons?" although she is a Titan pilot, Jiang Juan still knows about the weapons equipped by ordinary soldiers: "they are using heavy machine guns now? Are you going to make that into a duplex?"


    "Yes, for a 23mm machine gun, one shell is enough to kill alien creatures, but for a 12.7mm heavy machine gun, it''s just enough to break through the shell of alien creatures." Chen Xin has long planned to improve the lethality of individual weapons, but he hasn''t had any good ideas.


    Coupled with the busy work of various things, he could not spare time to design new weapons.


    But now Jiang Juan''s idea of double loading suddenly gave him new inspiration, and it just added the existing weapons together. It doesn''t need too many redesigned parts. It''s simple and easy to operate. It''s a very practical idea.


    "Your idea is very meaningful, and then there will be a formal reward for you." Chen Xin looked at Jiang Juan and smiled at her.


    However, Jiang Juan bit her lip and asked Chen Xin, "academician, can I not give a reward? I still want to change my Titan for a double mounted machine gun."

 Chapter 698

    Behind the defense line, a helicopter is preparing to land on the take-off and landing platform of the mobile base.


    "Come on! Where''s the stretcher? The wounded has a torn left chest and will be sent to the operating room immediately!" with the landing of the helicopter, the prepared medical staff rushed up and pushed the stretcher to the cabin door. After transporting the wounded out, they immediately rushed to the elevator to send the wounded to the operating room at the first time.


    The helicopter on the take-off and landing platform also shut down the engine, stowed the propeller with the help of ground crew, and was pushed into the hangar for supply and maintenance.


    At the same time, another helicopter that had completed servicing was pushed out. After the pilot checked it, he obtained the permission of the tower and took off quickly.


    Wang Jiang took his helmet, got off the plane, said hello to his co pilot, and said to the ground crew: "the left air inlet made a strange noise when he came back just now. It may be something. Please check it."


    "I see. When will your next flight take off?" the maintenance personnel wrote down Wang Jiang''s words and asked again.


    If the next shift of Wang Jiang is tight, the maintenance needs to be arranged urgently. Only some simple maintenance can be done to ensure that the aircraft can continue to fly.


    However, if there is enough time for the next shift, the ground crew can check the aircraft, troubleshoot some faults and replace worn parts to make the aircraft better.


    "Lao Li, when will we fly next?" Wang Jiang suddenly couldn''t remember and asked the co pilot aside.


    "Six hours later, so you still have time to eat and take a nap." the co pilot called Lao Li also took off his helmet. Under the light in the hangar, his face was full of fatigue: "I can''t carry it. Go to sleep first, and then go to the canteen to get something to eat on the plane when I leave."


    "OK, then go and have a rest first." Wang Jiangchong nodded to Lao Li, and then turned to the ground crew: "it will fly in six hours, so can it be done?"


    "I''m not sure. If it''s just the air inlet, it should be enough to change the filter element. You can finish it in almost two hours, but it''s hard to say how long it will take for other problems." the ground crew shook his head and didn''t dare to promise, but he still said to Wang Jiang: "But don''t worry, just make sure your plane can fly in six hours."


    "OK, please!" Wang Jiang said, and then walked towards the stairs.


    There were elevators leading to the decks of other floors in the hangar, but now all the elevators are transporting the wounded. Naturally, Wang Jiang doesn''t need to grab the elevator with the wounded, which will delay their treatment time, and it won''t take a few minutes to take the stairs.


    Go down the stairs inside the mobile base and come to the floor where the canteen is located. Wang Jiang glanced at the other pilots eating in the canteen, and then walked to the dining window.


    Because it''s not a meal now, the people who come to dinner are basically the pilots who have just returned.


    "Master, what else to eat?" Wang Jiang asked the master behind the window and looked at the dish in front of the master.


    "You''re lucky today. There''s also a scrambled egg with tomatoes. Do you want it? The tomatoes and eggs are fresh and shipped here today." the chef took a look at Wang Jiang''s flight suit and introduced it to him with a smile: "in addition, there are scrambled cabbage, protein meat and baked potatoes. What do you want to eat?"


    "Scrambled eggs with tomatoes? Let''s have one! Then we''ll order some protein meat, baked potatoes and fried cabbage." Wang Jiang was excited to hear that there were fresh scrambled eggs with tomatoes.


    Although the treatment of pilots has always been the best, and they can get the best material support even in wartime, under the overall lack of materials, even if the mobile base bears the responsibilities of field medical treatment and airport, and the material supply has always been guaranteed, there is an inevitable shortage of supply.


    Even pilots like Wang Jiang can''t guarantee that they can eat fresh vegetables and eggs every day.


    In fact, the materials delivered from the rear are delivered once every three days, not every time there are foods such as fresh vegetables and eggs. It can be said that the fresh vegetables delivered that day can only be eaten every few days.


    However, Wang Jiang doesn''t feel anything about this. Now the material supply is tight and it''s good to be full.


    Thinking of his grandfather''s generation, it was snowy to fry noodles in the air raid shelter during the war. They had to eat all together to have an apple. Now they can sit in the restaurant and eat delicious food without fighting hungry.


    Besides these dishes, the restaurant also has foods such as bread, compressed biscuits and emergency food. Although the taste may be worse, it can still ensure nutrition and energy.


    This makes Wang Jiang feel very satisfied.


    After dinner, he went to the master of the canteen and took two loaves and two packets of compressed biscuits. Wang Jiang took them back to the cabin assigned to him and Lao Li.


    He put the bread and compressed biscuits he brought back on the table and took a look at Lao Li who was already asleep. Wang Jiang shook his head, took off his flight suit and lay down on the bed.


    But instead of going to bed immediately, he took out a small book and pen and planned to write a diary.


    Originally, Wang Jiang didn''t have the habit of keeping a diary, but since the beginning of the war, after he was transferred to the mobile base, he saw too many things beyond cognition and imagination, and Wang Jiang gradually had the idea of writing something.


    In particular, Wang Jiang''s heart was touched by transporting the wounded back from the defense line for treatment every day and watching the fighting of his comrades in arms in front and the lost lives one by one.


    He records what he sees and hears and his inner thoughts every day, so as not to keep these emotions in his heart and affect his performance of tasks.


    Just writing, unconsciously, a small book is almost finished.


    "War!" Wang Jiang sighed and finished writing today''s diary. Then he put away his little book and closed his eyes to sleep.


    As pilots, their mission is very tight. They need to go back and forth to the front every day and transport the seriously injured to the mobile base for treatment. The flight mission is quite full every day.


    If not for aircraft maintenance, pilots need enough time to rest, and it is impossible to set aside six hours between their two missions.


    Therefore, Wang Jiang should seize these six hours to make up his sleep and restore his energy and physical strength in order to deal with the next task.

 Chapter 699

    "Hey, Lao Wang, get up!" Wang Jiang was woken up by Lao Li.


    He opened his eyes and saw that Lao Li had put on his flight suit again. Wang Jiang got up from bed and said to him, "Lao Li, don''t you sleep more? The bread and compressed biscuits on the table are for you. Fill your stomach first. I''ll wash my face."


    With that, Wang Jiang pulled the towel hanging on one side, came to the washstand in the corner of the cabin and washed his face.


    There is no toilet in the cabin of the mobile base, and only a simple washstand can be used for washing.


    After washing, Wang Jiang and Lao Li left the cabin together. Although they were still half an hour away from the mission time, they obviously needed to arrive at the hangar in advance to check the plane before flight.


    Although it is said that the ground crew will adjust the aircraft to the best state every time, the flight inspection between take-off is something that every pilot must do.


    When they came to the hangar, their plane had been prepared, and several ground crew were loading ammunition on the plane and filling the fuel tank with fuel.


    Although the electric powered nuclear battery helicopter has long been equipped with the army, the military has not replaced the original fuel engine version of the helicopter, but continued to use it after adding an air filter developed by Chen Xin.


    After all, the number of aircraft equipped with the whole army is too large. Even if it is only to transform the engine, it is a huge project, which requires a huge amount of resources and takes a long time.


    Therefore, in order to save costs, a large number of fuel engine versions of helicopters are still in service.


    However, there is no problem for Wang Jiang and Lao Li. The two versions of the aircraft are just different in power mode and there is no difference in driving.


    "Did you find out the reason for the previous abnormal noise?" said hello to the ground crew, Wang Jiang asked about the previous abnormal noise, and Lao Li began to check the plane before flight.


    "The inspection is clear. There is too much sand and dust sucked into the air inlet, and there is caking in some places. I have replaced you with a new air filter, and now there is no problem." the ground crew explained to Wang Jiang, took a picture of the plane on the side, and said: "the engine has also been inspected for you, and it is in good condition, but the wear of the bearing is a little serious. Although it can be used, it also needs to be replaced.


    This time it''s too short to change it for you. Just add some oil to lubricate it. Take it easy and change it when you come back. "


    "OK, hard work!" Wang Jiang wrote down the matter and nodded seriously. Then he got on the plane, started all kinds of equipment in the cockpit and checked the condition of the plane.


    At this time, Lao Li also finished the external inspection before the flight and sat in the cockpit.


    "Everything is normal through external inspection, ammunition and fuel have been filled up, and everything is in good condition." Lao Li informed Wang Jiang and asked him, "what about the mission briefing?"


    "Here it is." Wang Jiang handed the task briefing to Lao Li and explained to him, "it''s still the task to transport the wounded to the No. 7, No. 9 and No. 11 defense lines."


    When Lao Li heard Wang Jiang''s words, he couldn''t help picking his eyebrows, shaking his head and saying, "it''s another delivery task. When can I catch the attack task!"


    "Isn''t it good to transport the mission? It''s safe and can save people. I''d rather transport more wounded than go to the front line." Wang Jiang smiled. Although he was a little discouraged, he really felt that it was worth saving more people than killing more alien creatures.


    Lao Li just complained. When he heard Wang Jiang say so, he just shook his head and said nothing more.


    After all, it used to be peacetime. Helicopter pilots like them can rarely catch combat missions. It is the limit that they can hit ground targets at ordinary times. Now they are waiting for war, but they still can''t catch any combat missions, which still makes Lao Li feel a little frustrated.


    "All right, get ready to take off." after Wang Jiang checked all the instruments and meters of the plane and confirmed that the display was normal, he motioned to the ground crew to push himself out.


    However, when the ground service was ready to push the plane and Wang Jiang was ready to start the engine, a staff member suddenly ran over with a document, handed it to Wang Jiang, and said to him, "urgent task, area 14 needs investigation. You go and have a look."


    "Area 14? What''s going on?" when Wang Jiang heard the staff''s words, his eyes suddenly coagulated, and the whole person was nervous.


    Area 14 is one of the war zones, surrounded by the No. 7, No. 9 and No. 11 defense lines mentioned by Wang Jiang.


    "Just now, the No. 9 defense line sent a message that the frontal offensive of alien creatures has been strengthened. They detected a new tunnel. They suspected that there was a change in area 14 and needed air investigation." the staff explained to Wang Jiang and said helplessly: "now all the aircraft groups are flying, and you are just on your way, so this task is left to you."


    "OK, I know. We''ll find out what''s going on." Wang Jiang gave Lao Li the documents handed over by the staff. Only then did he make a commitment to the staff and start the aircraft engine.


    The staff quickly stepped aside and watched the ground crew push the plane onto the take-off and landing platform outside.


    With the rotation of the propeller, Wang Jiang pulled the joystick and flew up.


    "Isn''t area 14 always safe? Why is something wrong suddenly?" Lao Li looked at the documents and asked Wang Jiang on the plane.


    "Who knows? The No. 9 defense line said that the offensive of alien creatures had strengthened, and that if new tunnels were detected, we should always go and have a look!" Wang Jiang said, couldn''t help laughing and said to Lao Li, "it''s up to you, not the delivery task."


    "It''s good to have a chance to attack!" Lao Li still wants to do something. Simple air reconnaissance still can''t satisfy him.


    "No, I don''t want to lick the ground, mark the location of the new tunnel, find out what happened, and let the base launch missiles to knock the tunnel directly. It''s easy for us and others." Wang Jiang doesn''t have the strong desire to attack like Lao Li. He hopes to complete the task safely.


    However, he was not the kind of person who was afraid of things or avoided the war. After saying the previous words, he asked Lao Li, "have the used missiles been supplemented?"


    "Don''t worry, the ground service has been filled up. If there is any accident, it will be enough for those alien beasts to drink a pot." Lao Li''s face showed a kind and sunny smile and a row of white and neat teeth.


    Wang Jiang nodded. Although he didn''t want to encounter the situation that needed to fight, he was ready to face the battle.

 Chapter 700

    When the helicopter arrived at the target area, Lao Li looked down at the window and saw it was dark. Only the fire emitted by the shelling from time to time in the distance could make the scene below flash away, which made him mutter: "you can''t see anything."


    Although he couldn''t see anything on his mouth and his ears were full of the noise made by the rotation of the propeller on his head, Lao Li clearly knew that the darkness under the plane was countless alien creatures.


    "Lao Wang, do you want to turn on the light?" Lao Li asked Wang Jiang next to him.


    They are carrying out investigation tasks. They need to investigate what happened to alien creatures in this area, why the offensive of alien creatures will be strengthened, and where the new channel is located


    The light of fire produced by artillery bombardment alone, but there is no way to see all this clearly.


    However, it is still too dangerous to turn on the searchlight. Although there have been no flying units in alien creatures so far, humans are not without aircraft loss.


    In order to understand the situation of alien creatures, helicopters carrying out reconnaissance missions had been hit down from the sky by the vesicles of alien creatures after going deep into the enemy occupied area.


    Fortunately, they drive military helicopters, and the reconnaissance equipment is not only searchlights.


    Radar, infrared, low light level night vision... All kinds of equipment can detect alien organisms in a dark environment.


    Lao Li suggested turning on the searchlight just to see more clearly.


    However, Wang Jiang shook his head: "be safe. Don''t turn on the lights first. In case of a pile of vesicles below, we will have to be beaten down. It''s a small matter to cover the national flag. It''s a sin not to complete the task."


    Hearing what Wang Jiang said, Lao Li didn''t object. He just turned on the instruments and equipment at hand to observe the situation of alien creatures.


    The infrared display is still dark. The chitin shell of these alien creatures isolates the loss of heat, which is equivalent to being invisible under infrared vision.


    But this is not a big deal. There is no infrared vision, low light level night vision and biological radar.


    "How about the new biological radar scanning?" Wang Jiang asked Lao Li. At the same time, he carefully manipulated the aircraft to maintain a safe altitude and circled, looking for the new channel mentioned in the previous mission briefing.


    "It''s all over the ground. It doesn''t look special." Lao Li glanced at the radar display screen and reported to Wang Jiang. At the same time, he didn''t forget to express his emotion: "this new radar is much easier to use. Unlike the original one, it doesn''t show alien creatures at all."


    The fact that the previous biological radar could not scan alien organisms had been found when Chen Xin first encountered alien organisms, but the reason was not clear.


    At that time, the military also felt a big headache and urgently asked the rear scientific research department to solve the matter.


    Later, after several live samples were captured and dissected by biologists, it was found that the surface of chitin bones of alien organisms was covered with a special structure. They could absorb radar waves emitted by radar without forming reflection, so they could show nothing on the radar.


    Later, Chen Xin upgraded the military''s existing radar and adjusted it to scan alien creatures through the radar.


    "Twilight display? What can you see?" Wang Jiang asked Lao Li. Their goal was to find the newly generated channel: "did you see the new channel mentioned in the mission briefing?"


    "I can''t see it for the time being, but look at the moving direction of these alien creatures. They seem to come from 9 o''clock. Let''s go there." Lao Li quickly analyzed the results displayed on the screen and said to Wang Jiang.


    Wang Jiang nodded, pulled the joystick and controlled the plane to fly in the direction indicated by Lao Li.


    The area they needed to investigate was not large. In addition, they flew in the sky. They soon found something unusual.


    "What''s that?" Wang Jiang looked at the shimmering display screen, on which a huge thing like a hill was climbing out of the newly formed channel, which was very conspicuous on the screen.


    "I don''t know, but no matter what it is, I think we should kill it!" Lao Li also felt his back cool at this time. It was not fear, but an instinctive fear when creatures met natural enemies.


    Wang Jiang felt the same when he heard Lao Li say he would kill it. He opened the communication channel and shouted to the rear base: "falcon calls eagle''s nest, Falcon calls eagle''s nest, we found something abnormal in area 14! An alien creature more than 30 meters high is climbing out of the ground and requesting fire support!"


    "Falcon, Falcon, this is the eagle nest. What did you find? Please explain the situation!" in the communication channel, the mobile base received Wang Jiang''s call and hurriedly responded to him. At the same time, it was also preparing for the missile launch.


    "Eagle''s nest, eagle''s nest, I''m a falcon. We carried out a reconnaissance mission in area 14 and found an alien creature with a height of more than 30 meters and a huge body climbing out of the surface through a new channel. We asked for an immediate attack! The missiles we carry can''t resist such a large target!" Wang Jiang repeated again and cut the picture they had taken, Let the mobile base see.


    In the command room of the mobile base, everyone showed the same surprised expression through the picture sent back by Wang Jiang.


    The officer in charge of command immediately grabbed the communicator and said to Wang Jiang, "falcon! Immediately provide accurate coordinates to guide the missile!"


    "Falcon received!" Wang Jiang heard that he asked them to provide coordinates to guide the missile. He quickly sent the accurate coordinates calculated by Lao Li Gang. At the same time, he did not forget to add: "this monster has been separated from the underground passage. It is at least 70 meters long. At present, it is approaching the No. 9 defense line at a speed of 20 kmh!"


    "Yingchao, the missile is on the way and needs your terminal guidance!" the officer said to Wang Jiang, while the operator on the side has pressed the missile launch button.


    At this time, on the top deck of the mobile base, a missile launch port has been opened, and a cruise missile spewed flames from the launch port and flew towards Wang Jiang''s position.


    When Wang Jiang heard that the missile had been launched, he settled down and said to Lao Li: "Lao Li, prepare for laser guidance. We can''t let this monster close to the defense line!"


    "I see!" Lao Li answered. While opening the laser guidance equipment, he was ready for terminal guidance. At the same time, he also opened the launch insurance of all weapons on the helicopter, and was ready to repair the knife in case the missile didn''t kill the monster.

 Chapter 701

    The missile pierced the night sky and, under the laser guidance of the helicopter, accurately hit the alien creature whose body was like a mountain.


    However, to everyone''s surprise, when the fire of the missile explosion dispersed, the monster with flame still flowing in front of everyone.


    Although the missile broke through the outer shell of the alien creature, it did not kill it, but caused heavy damage to it, ignited part of its body fluid, and flowed wantonly along the broken shell of the monster, like a huge torch.


    The burning caused by the ignition of body fluid in the body made the monster bear great pain. It issued a violent cry and spit liquid from the mouthparts of the head.


    After the liquid was sprayed out, it burned quickly, as if the monster was spitting fire.


    "Damn it, this TMD is a siege weapon!" when Wang Jiang and Lao Li saw that the flame emitted from the monster''s mouth was tens of meters away, they naturally thought of what terrible consequences would happen if the monster approached the defense line.


    Even the missile launched by the mobile base could not kill it. It could only break through its shell. Even looking at the monster''s lively appearance, Wang Jiang even felt that the missile just now could not be regarded as seriously injuring the monster.


    With such strong defense, if it approaches the defense line, I''m afraid even the Titans will be difficult to kill the monster.


    Such a huge fire breathing monster is close to the defense line. It can destroy the whole defense line by itself!


    Luckily I found it here! Wang Jiang and Lao Li looked at each other and saw happiness from each other''s eyes.


    But now is not the time to be happy. The monster is not dead yet!


    Wang Jiang continued to call the mobile base in the rear to make another attack. At the same time, he also pushed the joystick and controlled the helicopter to fly towards alien creatures.


    "Lao Li, get ready to attack, all fire!" Wang Jiang shouted to Lao Li.


    "I see!" as an old partner, Lao Li clearly knows what Wang Jiang is going to do: "the power of our missiles and rockets is limited. We fly to the place where the missiles exploded just now!"


    "I see. Pay attention. This monster will spit fire. There must be some place in its body to store fuel and light it directly!" Wang Jiang speculated as he watched the monster still spit out fire.


    At this time, Lao Li showed a confident and serious expression on his face: "look, we are the military region''s martial arts competition and the first to hit the ground target!"


    With that, Lao Li manipulated the weapons carried on the helicopter and, with the cooperation of Wang Jiang, made every effort to output the blasted area on the monster''s back.


    Missiles, rockets and machine guns hit the back of the monster who was constantly venting his anger and pain in an instant, making it feel more pain.


    At the same time, I don''t know whether Lao li really shot as he said, or was lucky. With his shooting, the monster''s back suddenly exploded violently, and even blew up the shell on one side of the monster''s body!


    "Lying trough, Lao Li, did you really hit it?" Wang Jiang quickly held the joystick to stabilize the helicopter to avoid being overturned by the airflow generated by the explosion.


    "I don''t know, but it looks like it''s hitting!" Lao Li looked at the monster below and couldn''t believe it.


    But the monster has obviously not been completely eliminated. Although the explosion has caused serious damage to the monster, it is obviously not enough to kill it.


    However, fortunately, the second missile launched by the mobile base has arrived. Wang Jiang hurriedly asked Lao Li to conduct laser guidance, while he controlled the helicopter to pull away quickly to avoid being involved by the missile explosion.


    As the missile falling from the sky plunged into the monster''s back like a sharp sword, there was another violent explosion, and the monster was finally blown in two.


    Seeing that the monster was blown in two, Wang Jiang and Lao Li informed the mobile base of the result, and then returned to the mobile base under the instructions given by the mobile base.


    This monster is also the first encounter of human beings. As the first witnesses, the data on Wang Jiang, Lao Li and their helicopter are very valuable, which helps human beings understand this new monster at the first time.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "Let''s talk about your specific impression of this monster." Chen Xin, who hurried to a room in the mobile base, threw the monster photo taken by Lao Li on the table and asked him and Wang Jiang.


    At this time, Chen Xin didn''t have time to be polite or say more. He went straight to the point.


    Wang Jiang and Lao Li looked at each other. They also knew the importance of this matter, so Lao Li first said, "this monster is very big. When we arrived at the target area, it just poked its head out of the geography, because it is too big and we have never seen it before, so we called the mobile base and asked them to launch missiles to destroy the monster."


    Lao Li couldn''t help swallowing his saliva. Although he didn''t feel it when he drove a helicopter to attack the monster, now he returned to the rear and calmed down. Both he and Wang Jiang were surprised at their boldness.


    At that time, they were likely to be destroyed and killed. They didn''t even need more. They should say goodbye when they were sprayed by the monster.


    Because according to the detection results of various instruments carried on the helicopter, the flame emitted by the monster was more than 1000 degrees, which was enough to destroy the two helicopters in an instant.


    "What we wanted at that time was to destroy the monster as much as possible, so when the first missile didn''t kill the monster, we didn''t think too much and directly flew up to attack the monster''s wound." Wang Jiang told behind Lao Li. Although his tone was calm, people could still feel his mood at that time: "Missiles, rockets and machine guns, all the weapons we can use.


    I don''t know if we were lucky. We hit an organ in the monster, so it exploded again and exploded the shell on one side. At this time, the second missile also arrived. I asked Lao Li to guide the second missile directly into the monster''s back and blew it in two. "


    Listening to Wang Jiang''s words, Chen Xin couldn''t help picking up his eyebrows and asked him, "what organ did you hit, causing the monster to explode?"


    "Yes, the monster can spit fire, and the first missile attack ignited it. It flows out like fire, not blood." Wang Jiang recalled and said to Chen Xin.


    This situation made Chen Xin''s eyes freeze and guess, "then you may hit its fuel storage organ."

 Chapter 702

    "Fire breathing monster... Damn it!" after asking the pilot about the fire breathing monster, Chen Xin became very bad and even hammered the table in front of him.


    And he also surprised the others around him. Wang Jiang and Lao Li, who had not left, couldn''t help looking at the scientific research academician in surprise and looking at each other. Lao Li asked, "what''s wrong with this leader?"


    Facing Lao Li''s inquiry, Chen Xin just looked up at him with a very bad face and said, "you are also a soldier. I ask you, if it was just a conflict between soldiers at the beginning, the weapons were limited to light weapons, and then one party suddenly brought out tankra, what do you think it means?"


    "This..." Chen Xin''s question came so suddenly that Lao Li didn''t turn his head for a moment.


    On the other hand, Wang Jiang reacted, stared at Chen Xin, and asked incredulously, "is the war escalating?"


    "Yes, before, it was just a battle between ordinary soldiers and subordinate descendants between us and alien creatures, but some time ago during the Honghu campaign, we threw 30 tactical nuclear bombs to escalate the war. Now it''s the turn of alien creatures to attack." Chen Xin nodded with a dignified look. Obviously, what Wang Jiang said is exactly what he thought.


    "But although this fire breathing monster is very powerful, it can''t be compared with a nuclear bomb?" Lao li felt that he didn''t understand. Although the monster they saw was indeed huge and had amazing defense, even if the mobile base used two missiles to kill it, it still couldn''t be compared with a nuclear bomb.


    "It''s not such a comparison, and I don''t mean that aliens sent out this huge fire breathing monster only after we used a nuclear bomb." Chen Xin shook his head, explained a sentence, but left without saying anything more.


    The emergence of such large combat units by alien creatures has a great impact on mankind.


    This time, the helicopter found it early and didn''t let this large monster close to the defense line, but next time, no one can guarantee to find it so timely and destroy it so easily.


    Therefore, the defense line must be adjusted on a large scale. There are too many things to be rearranged, such as firepower allocation, early warning system and response plan. He still has a lot of work to do next.


    After Chen Xin left, Lao Li asked Wang Jiang, "Lao Wang, what''s the matter with that monster? If alien creatures have such a monster to leave from the beginning, why don''t they send it to play at the beginning? They have to be bombed by a nuclear bomb before they send this monster to fight?"


    "Should it be a production problem? I heard that although alien creatures are creatures, they reproduce very fast, but even if they are fast, it takes time to grow. It will take a long time for such a big monster to grow up?" Wang Jiang guessed, only analyzing according to the information he knows.


    Lao Li was relieved to hear him say this: "fortunately, we knocked out one. If the number of this thing increases, it will be a big trouble!"


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    In fact, fire breathing monsters are really a big problem.


    In addition to the one knocked down by Wang Jiang and Lao Li, 17 giant fire breathing monsters were sent out by alien creatures. They climbed out of the ground and attacked the human defense line in different places.


    This powerful monster really had a great impact on the defense line. Of the 17 giant fire breathing monsters, only three were found and cleared before approaching the defense line, and the remaining 14 were found after approaching the defense line.


    Although the air force and missile forces responded in time and killed all 14 giant fire breathing monsters, several of them really touched the defense line and launched attacks, causing great damage to the defense line.


    The casualties of front-line soldiers, the shaking of the whole defense line after being attacked, and the impact of the emergence of giant monsters on morale


    The impact of this giant monster is not only that the enemy has added an indestructible arms, but also affected all aspects of the war.


    "We need to adjust our defense line and deploy enough missile troops! This monster can''t do anything with conventional weapons!" the general knocked on the map with a grim look.


    Although 17 giant monsters have been eliminated this time, since 17 can appear this time, at the rate of alien reproduction, it may be 71 next time!


    So human beings must make enough response, at least have ways to deal with them.


    However, now, the only way to kill effectively is to attack with missiles. Although conventional artillery can break through the shell of this giant monster, it is difficult to damage effectively.


    After all, with a huge body more than 30 meters high and more than 70 meters long, if you want to kill it by shelling, it is tantamount to cutting off a hill of the same volume by shelling.


    Not impossible, but requires a considerable amount of ammunition.


    And in this process, the monster is not static. If you can''t kill the monster in time and effectively and let it close to the defense line, it will undoubtedly cause huge losses and impact.


    "The alert density of the air force and land airlines must be increased. We need to find these giant monsters more effectively and eliminate them all before they approach the defense line!" an officer put forward his own suggestion, which was quickly recognized by others.


    However, another officer also put forward different opinions as a supplement: "relying on the air force and land Airlines alone is not enough. I think a new early warning system needs to be established. Such a big monster cannot be found by planes and helicopters alone!"


    "I agree with that. If this giant monster can be found immediately after climbing out of the surface and killed with missiles, it can''t threaten the security of the defense line no matter how powerful it is!" the general couldn''t help nodding his agreement when he heard the officer say so.


    Indeed, if it can be found in time and killed in time before these giant monsters approach the defense line, it will not pose a threat to the defense line.


    At this time, another officer suddenly asked: "Can we arrange more mobile bases behind the defense line? This time, the mobile base has performed very well in defending against this monster! It can quickly send helicopters to investigate the target area, launch missiles to attack immediately after finding the target, and can also work as a field hospital and airport at ordinary times. At the same time, it also has enough mobility How practical! "

 Chapter 703

    Although the attack of the giant fire breathing monster had a great impact on the human defense line, the excellent performance of the mobile base in this attack also successfully made the military pay more attention to the mobile base.


    Originally, because of its high cost and less practical functions in peacetime and war, the mobile base did not allow the country to include it in the mass production plan, but decided to master the relevant technology.


    Although Chen Xin successfully installed the weather controller on the mobile base through various ways and new use plans, which made the senior management have a certain interest in it and decided to carry out production, there was no large-scale production in the end, but only one or two handhold technologies were trial produced.


    And even one or two of these trial produced units have not officially entered the service stage so far, but are still outfitting and testing.


    However, now the military suddenly felt that it was good, so the two mobile bases in the rear, which had basically completed outfitting and commissioning, were urgently deployed to the Dongting Lake area to support the defense line.


    At the same time, the mobile base equipped with weather controller was also transferred. The military built a new defense system with these four mobile bases as the fulcrum.


    In this defense system, the mobile base is mainly used as a missile launching platform and a battlefield airport. At the same time, it provides battlefield medical services and battlefield intelligence nodes.


    Through the information collection and communication network support of the mobile base, there are mobile radar stations and missile launch positions around the mobile base. The intelligence obtained through the deployed radar and front-line and air reconnaissance not only provides intelligence support for the whole battlefield, but also shoulders the task of fire attack.


    After all, relying solely on the mobile base as the missile launch platform, the firepower delivery volume is still not enough, and the coverage area is not enough.


    After the establishment of this system, relying on the cooperation of mobile base, abnormal radar station and missile launch position, the defense line was indeed stabilized and played a very excellent effect.


    But this also raises another problem, that is, the military wants more mobile bases.


    "If you want more mobile bases, build them! Why do you ask me? Haven''t the drawings and production technology been handed over to the relevant departments?" Chen Xin was puzzled when he came to find his own military representative and senior representative.


    It really makes Chen Xin feel very strange. After all, the military needs more mobile bases, and the country has the ability to manufacture mobile bases. Just build them directly. Why do you come to find yourself?


    Let yourself be responsible for the production of mobile base? It only needs a transfer order from the top.


    Do you think that the current mobile base production consumes too many resources and the production cost is too high, and you hope to improve the design and reduce the production cost?


    Chen Xin was wondering. The representative of the military had explained: "academician Chen, you misunderstood. In fact, we came to you in the hope that you could design a new mobile base to better support regional defense."


    "Is the existing mobile base not enough to complete this task? What specific requirements do you have for the new mobile base?" Chen Xin looked at the military representative and wanted to hear his specific requirements.


    Hearing what Chen Xin said, the military representative and the high-level representative looked at each other and said directly to him, "in fact, the existing mobile base has indeed played a good role. We are also very satisfied with this large mobile facility, but we feel that the firepower delivery capacity of the existing mobile base is still lower."


    "Lower? Do you want stronger firepower delivery capability and battlefield support capability?" Chen Xin understood what the military representative meant.


    The military representative saw that Chen Xin understood and smiled: "that''s what you mean! Academician Chen, the existing mobile base was built for the main purpose of future logistics support. In the use of this war, they really played a good role in logistics support.


    But now the main purpose of the mobile base has changed from logistics support to battlefield support. We need the mobile base as the defense support node of the battlefield to deal with the existing and possible more powerful combat units of alien organisms.


    Accordingly, the existing mobile bases are not enough in terms of firepower and battlefield support. "


    "I see. The current mobile base is somewhat similar to the amphibious landing ship of the Navy, but now you think it can no longer meet the operational needs and needs a heavy aircraft carrier?" Chen Xin thought over the words of the military representative and changed a new version.


    "That''s what that means. The state hopes academician Chen that you can redesign a new mobile base and build it into an existence similar to a heavy aircraft carrier to better support battlefield operations." at this time, the high-level representative saw that Chen Xin had understood their purpose, so he told him the requirements of the military and the high-level.


    Chen Xin nodded clearly, but fell into thinking: "to improve the battlefield support capability, the fire delivery capability of the mobile base must be improved. At the same time, it is not only used as a helicopter take-off and landing platform... If you want to be similar to the existence of heavy aircraft carriers, take-off and landing fighters?"


    "I have such an idea. After all, the military airport available to the air force is still some distance away from the Dongting Lake theater. Although we are also building a new military airport and adjusting the deployment, it is true that a fixed airport is not as good as an airport that can be moved at will." the military representative nodded and expressed his affirmation to Chen Xin.


    "It''s a big thing. It needs to be redesigned in all aspects of mobile and deployment. I''m afraid I can''t come up with a good plan in a short time. If you want to use it immediately, I''m sorry, I''m afraid I can''t do it for a while and a half." Chen Xin looked at the military representative and hesitated, but chose a euphemistic expression that he couldn''t do it.


    "I have such an idea. After all, the military airport available to the air force is still some distance away from the Dongting Lake theater.

 Chapter 704

    Although Chen Xin said that it was impossible to design a larger mobile base in a short time, both the military and senior management entrusted the task to him.


    Facing the entrustment of the military and high-level officials, which is half order and half request, Chen Xin can only promise.


    After all, this is really related to the victory of human beings in the war against alien creatures. If possible, Chen Xin also hopes to provide more advantages for the country and mankind.


    The design of a large mobile base is naturally not as simple as the previous mobile base.


    It can even be said that because of their different functions and body shapes, they almost completely redesigned one.


    After all, with so much body enlargement, the whole hull structure and travel mode must be redesigned, rather than simply enlarging the original mobile base.


    Although we can learn a lot of technical experience from the original mobile base, large mobile bases still can''t copy these experiences mechanically.


    While thinking about how to design a large mobile base, Chen Xin also picked up a paper pen and drew a sketch on the paper.


    According to the requirements of the military, in fact, an aircraft carrier is the most in line with their requirements, but it is obvious that the aircraft carrier can not reach the shore, and the previous disaster has also lost the use of all naval ships, and the aircraft carrier is no exception.


    "So do you want to design a land aircraft carrier?" Chen Xin looked at what he sketched on the paper, which was similar to the aircraft carrier with tracks, but shook his head.


    The drawing is simple, but if you really want to design, it is not so simple to install tracks under the aircraft carrier.


    Besides, the displacement of a large aircraft carrier is more than 70000 tons, and the largest can even reach more than 100000 tons. Such a huge weight doesn''t matter at sea. There will be no problem if it is supported by sea water.


    However, on land, these weights are all pressed on the ground, and any uneven stress may cause the whole hull to overturn or even break.


    Moreover, a runway that can take off and land fighters, even if it is only a carrier aircraft, needs to be at least two or three hundred meters long. Such a large movable object moves on the ground, not to mention the problem of load-bearing and force, whether there is a terrain that can pass through is a problem.


    However, since I took the job, I still have to do.


    The requirement put forward by the military is that fighters can take off and land, but it is unrealistic to make a runway as long as an aircraft carrier.


    However, fighter take-off and landing is not the only way to taxi on the runway. The catapult or vertical take-off and landing adopted by the aircraft carrier itself in order to shorten the runway length can be used as a reference.


    "Use vertical take-off and landing to shorten the runway length and increase the missile launching well..." Chen Xin gradually sorted out his ideas. With the clarification of his ideas, he also gradually had a general direction.


    As Chen Xin gradually found the direction, the sketch on the drawing became clear: "the vertical take-off and landing position is set on the deck, the lifting platform is installed, the hangar is placed under the deck, and the missile launching well is installed on the side, which can be launched obliquely and can be put away at ordinary times..."


    In this version of the design, Chen Xin did not lengthen the runway too much, but changed the takeoff and landing platform protruding from the side of the hangar of the mobile base to be placed on the top deck.


    In addition, the vertical take-off and landing mode is adopted. Only the top deck is used as the take-off and landing stand, and it is not used as the runway, so it is not necessary to lengthen the length too much.


    As for the missile launch site, it was originally placed on the top deck. Although the launch site of the original mobile base can be retained after the top deck is used for take-off and landing, in order not to affect the take-off and landing of aircraft on the deck.


    After some consideration, Chen Xin put it on the side of the mobile base and made it into an inclined angle. The bottom is in the mobile base and the launch port is outside.


    "Such a change is almost the same. Next, we need to make it bigger." Chen Xin looked at the things he designed and nodded with satisfaction.


    Although it takes a lot of process and verification to really convert the drawings into real objects, and many places need to be modified according to the actual situation, at present, this is only a conceptual design drawing, which can reflect the design idea, but it doesn''t need to be done in too detail.


    Therefore, it did not take long for Chen Xin to complete the drawings of the so-called large mobile base.


    The large mobile base on the drawing is indeed larger or longer than the mobile base currently used by the military.


    After comprehensive consideration, although Chen Xin did not make the top deck into a runway, he still lengthened the overall length of the mobile base, and installed catapults and blocking cables on the top deck, so that it can be used to take off and land aircraft when necessary.


    Of course, although such a function is designed, the main take-off and landing mode of large mobile bases is vertical take-off and landing. Although it needs to redesign a fighter that can take-off and landing vertically, Chen Xin thinks it''s worth it.


    As for the lengthening of the hull, it is not only to make the top deck have the function of runway, but also to expand the hangar so that it can accommodate more fighters.


    After all, fighters are different from helicopters. They have stronger combat effectiveness and larger size, so they need a large enough hangar to accommodate fighters.


    For this reason, the deck of the aircraft carrier is actually very high. Although there is a huge space inside, the largest space is always the hangar.


    Therefore, when designing a large mobile base, Chen Xin also removed the deck under the original hangar and turned it into a part of the hangar, so that there is more space in the hangar to accommodate more fighters.


    In addition, it is the missile launch port on the side. Although the inclined way is adopted to make some launch mechanisms extend out of the hull, most of the structure is still inside the hull. Chen Xin has also made some adjustments, but the overall change is small.


    Chen Xin did not make much adjustment in other parts of the mobile base, but optimized the internal space structure and expanded the area used as a field hospital.


    "It looks ok, but I''m afraid the power system and mobile mechanism need to be redone!" the structural design of the superstructure is easy to do, but the mobile mechanism at the bottom is the focus of this large mobile base, which is the part that makes Chen Xin feel headache.


    Fortunately, he didn''t need to worry about it alone. After reprocessing the completed conceptual design drawing and transforming it into a more detailed and formal design drawing, Chen Xin sent the drawing to the relevant units and asked them to put forward the design scheme according to the design drawing.


    For Chen Xin, what he wants is not technology, but ideas. As long as ideas can solve problems and are practical, he can turn them into practical technology.

 Chapter 705

    After transferring the design drawings of the large mobile base, that is, the land aircraft carrier, to the relevant departments, Chen Xin did not spend more time on this matter.


    Although the military shows the attitude that it can''t wait to use the land-based aircraft carrier tomorrow, in fact, both the military and senior management know that even if Chen Xin is hanging up, it can solve the technical problems in the shortest time, but it is still not a thing that can be completed in the short term to convert such a large thing from drawings to physical objects.


    Even before the disaster, it took several years to build an aircraft carrier with the industrial strength of Yanguo and the drawings and technology have been improved.


    Therefore, after the military made such a request, it did not urge it too much.


    As for Chen Xin himself, after completing the design drawings, he turned his attention back to the study of alien creatures.


    The communication experts and physicists who had been transferred before have made a breakthrough after studying, and through the analysis of the existing data, they can infer the cause of the collapse of the alien biological attack and infer the impact of the EMP impact caused by the nuclear explosion.


    "EMP shock? Why doesn''t electromagnetic interference work?" Chen Xin didn''t know much about this. After understanding the inferences made by physicists and communication experts, he asked him.


    A physicist explained to Chen Xin: "this is mainly caused by the different principles and modes of action of EMP impact and electromagnetic interference. In short, EMP destroys electromagnetic equipment, while EMI... That is, electromagnetic interference only affects communication quality and will not damage equipment."


    Hearing what physicists said, Chen Xin raised his eyebrows, thought for a moment and said, "your consciousness is that the EMP impact produced by the nuclear explosion has damaged the organs used by alien organisms for communication, resulting in the impact on their communication command; but our electromagnetic interference means only interfere with their communication, and the other party can ignore this?"


    "You can say so." a communication expert nodded and continued to explain: "EMI interference can be countered by technical means, such as changing frequency and improving signal strength, which is harmless to the equipment itself. When the interference disappears, the communication can return to normal.


    But EMP is different. It is instantaneous damage. After EMP, the damaged equipment is difficult to restore normal use in a short time. Even if the equipment is not damaged, it is difficult to restore communication in a short time.


    Therefore, according to the data we have and the experiments conducted with the assistance of comrades in the biological field, we have confirmed that EMP can cause damage to the communication organs of alien organisms, so we can come to this conclusion. "


    "I see. In that case, can it be applied to actual combat?" the reason for the setback of alien attack was found. Chen Xin didn''t care about the specific reason. He just wanted to know whether it could be used to deal with alien creatures.


    The two experts looked at each other, discussed and nodded: "if we can artificially create a high-intensity EMP impact, it can indeed have a certain impact on alien organisms, but we can''t judge how big the impact is. After all, there is a lack of relevant data and information, and we can only infer based on the existing information."


    Chen Xin nodded clearly and said to the two experts, "it''s hard. Please organize these conclusions into a report and submit it to the high level. As for whether EMP impact can be applied to combat against alien creatures, I will arrange experiments as soon as possible, and I need your assistance at that time."


    "No problem, please rest assured to give it to us." the two experts knew that this was due and did not object.


    After communicating with the two experts, Chen Xin also plans to implement this matter as soon as possible.


    Now that you know the reason, it''s not difficult to simulate similar scenes and copy similar effects.


    In fact, mankind already has the technology of EMP impact applied to the military field, and the EMP bomb was born.


    Just facing a group of creatures, no one would think of using these weapons against electronic devices to deal with living creatures.


    But since it is useful to judge this way, humans will not struggle. It was not used to deal with biological problems.


    Some EMP bombs were soon transferred by Chen Xin, and then tested in various ways.


    After some experiments, the conclusion is gratifying, but the effect is not as good as expected.


    These EMP bombs transferred by Chen Xin have a limited range of influence. Within their scope of action, it can be observed that alien creatures are affected. They lose control and suddenly become anxious and afraid, but soon they will be cleared by other alien creatures still under control around them.


    Yes, the aliens themselves actively cleared these uncontrolled daughters after being impacted by EMP.


    Obviously, for alien creatures, they don''t mind this little loss. On the contrary, they can''t accept the loss of daughter control more than the loss of these daughters.


    From the results of this test, it is certain that EMP impact will cause damage to alien creatures, but this damage has little impact on combat.


    Unless a large-scale EMP impact can be produced, it is possible to produce results that can affect the war situation.


    The EMP impact caused by the previous nuclear explosion has a wide range of influence, affecting the upper nodes of alien creatures hidden underground, which will cause a setback in the offensive on the battlefield.


    In order to achieve a similar effect, it is obviously necessary to create an EMP impact of at least the same scale.


    This is somewhat tricky for mankind. After all, there is probably no good way to create such a large-scale EMP impact except nuclear explosion.


    However, Chen Xin thought of one thing that could be used, that is, the weather controller.


    In addition to nuclear explosion, thunder and lightning will also form EMP impact. In the past, thunder and rain did not turn on the TV because of this reason.


    As long as a large enough thunderstorm can be produced, it can also produce a large enough EMP impact.


    Now, the mobile base equipped with weather controller is configured behind the defense line as part of the battlefield support system.


    Just use it to create a large-scale thunderstorm, we can know whether the EMP impact caused by thunderstorm will have a large enough impact on alien organisms.


    After the idea took shape, Chen Xin soon submitted the idea.


    The military has also drawn up an operational plan based on Chen Xin''s idea and the relevant reports submitted by experts.

 Chapter 706

    Over Dongting Lake, thunder clouds have begun to stir, and lightning strikes from time to time, briefly lighting up the sky.


    At this time, the atmosphere on the battlefield seemed a little dull. Although it was still actively defending, it only needed a little attention and attention to find what everyone seemed to be preparing, as if holding a breath.


    Recently, with the completion of YONGGU fortification construction, the defense conditions of the defense line have been improved a lot.


    The newly built bunker allows soldiers to have a safer fighting environment. They can stand in a safe bunker and use the installed defense machine guns to kill the attacking alien creatures more effectively, instead of being nailed to the defense line and fighting with the alien creatures with the weapons in their hands during the whole rotation time.


    The solid bunker can effectively resist the attack of combat offspring and worker ant offspring. As the defense support of the defense line, it can also be used as a place for soldiers to rest and rotate, making the rotation of troops on the battlefield more efficient and safer.


    In addition, the newly installed defense machine guns on the defense line and the anti-aircraft guns that should almost withdraw from the stage of history have excellent lethality to alien creatures after being leveled.


    With these conditions, the pressure on the defense line should have been reduced a lot. It was true before. The soldiers did become calm after the fortifications were repaired.


    But not today.


    After the senior management approved Chen Xin''s plan to use the weather controller to create a thunderstorm, the front-line defense forces naturally received a notice to cooperate with the test.


    Previously, due to the problem of human combat power and quantity, mankind has been in a passive defensive position in this war. Even if the nuclear bomb, the most powerful weapon mastered by mankind, is still just stabilizing the defense line and unable to fight back.


    We have been doing our best to resist the attack of alien creatures before. Naturally, we have no free time to think about this.


    However, when the defense line is stable and everyone''s survival pressure is not so great, everyone can''t help thinking when mankind should counter attack.


    As the high-level ordered the grass-roots soldiers to cooperate with the experiment, everyone knew that this was preparing for the counter attack. Naturally, they held their breath and wanted to take this opportunity to teach these alien creatures a lesson and let them know that human beings are not easy to provoke.


    In addition to the soldiers on the front line, other departments with authority to know about the experiment are also holding their breath. Everyone hopes that the experiment will achieve good results so that mankind can have effective means to alien organisms.


    In the expectation of everyone, the experiment finally began.


    The clouds in the sky began to stir violently, and lightning danced among the clouds with the strong wind.


    Looking at the tyrannical Thunder Dragon in the sky, some soldiers on the defense line were shocked. Some even couldn''t believe that such a brilliant heavenly power was a power that human beings could control.


    The scope of this test is wider than that of any previous weather controller startup test. For this test, the military even dispatched the air force to help spread the chemicals used in the test, so that the influence range of the test reached the maximum theoretical value.


    For this reason, the whole East Dongting Lake, which was selected as the experimental area, was shrouded in thunder clouds.


    When the thunder clouds in the test area release lightning due to the influence of the weather controller, the spectacular scene shrouded in thunder for hundreds of miles is really amazing and frightening.


    Of course, this spectacular scene is not the main purpose of this test. The main purpose of this test is to test the effect and effect of EMP impact on alien organisms caused by lightning.


    Therefore, only cloud discharge can not achieve the purpose of this test.


    In fact, before the experiment began, the military had sown a large amount of metal powder in the air according to the experimental requirements to guide the release of charge in the clouds.


    Chen Xin''s special lightning needle was also thrown on the ground in order to lead lightning to the ground and lead the energy of lightning into the ground at the same time.


    With these preparations, as the weather controller increased the energy release, the first lightning finally struck down.


    Just like a light that cuts through the night, it hits the earth with a roar and releases powerful energy.


    A simple lightning strike can not cause much impact on alien creatures. Even if it is hit, it is nothing more than killing a handle body, which can not play any role.


    But when one thunder after another constantly split from the sky and enveloped the whole earth like rain, the alien creatures visible to the naked eye became agitated.


    "We have observed the commotion of alien creatures, report to the above!" an observer observed the commotion of alien creatures on the forward position and shouted at the correspondent.


    Hearing what the observer said, the correspondent quickly picked up the phone and reported the discovery to the above.


    Reports like this occurred at all observation posts throughout the defense line, and a large amount of information was summarized into the headquarters.


    "Academician Chen, the frontier reported that there was an obvious commotion among alien creatures!" a staff officer excitedly informed Chen Xin of the news.


    "Commotion? Isn''t it a setback like the previous nuclear explosion?" Chen Xin didn''t seem too excited. When he heard the news, he just rubbed his chin and fell into thinking.


    On the other hand, a physicist said: "the EMP impact effect produced by nuclear explosion is stronger than that produced by lightning. This difference is normal."


    Hearing what the physicist said, Chen Xin shook his head slightly and said, "I''ve expected the effect to be different, but why is it just a commotion..."


    "What''s wrong?" an officer in the headquarters asked.


    When he asked this question, others in the headquarters also looked at Chen Xin.


    Chen Xin did not speak, but a biologist on one side explained: "if the communication and control of alien creatures are affected, it should be a riot or a setback like the last time, but just a riot, it proves that lightning has no great impact on their communication, and the lower offspring are still under the control of the higher offspring."


    "The opportunity of counterattack we expect is to have a significant impact on alien creatures, weaken their combat effectiveness and create the possibility of counterattack." at this time, Chen Xin also took over the topic and expressed his view: "if it''s just a commotion, the impact can''t constitute a condition for counterattack."

 Chapter 707

    When Chen Xin was worried that the effect of thunderstorm did not meet expectations, the thunderstorm clouds over the East Dongting Lake area rolled more and more severely.


    The frequency of lightning strikes began to be faster and faster. Lightning continued to hit the ground like heavy rain, and even lit up in the sky. The continuous lightning even formed a lightning network over the whole East Dongting Lake area.


    Before a flash of lightning dissipates, new lightning will appear, so that the whole sky can only see dazzling and dazzling thunder at this time.


    However, even so, the front observation post still stared at the sky ahead, and dared not move its eyes even if it was dazzled by lightning.


    Because this is their task to monitor the situation of lightning and the impact of lightning on alien organisms.


    "Why hasn''t there been much change?" in an observation post, the correspondent also looked at the alien creatures still attacking in front with a pair of binoculars, and his expression became a little anxious and impatient.


    As frontier observation posts, they have been told before for this mission. If there are major changes in alien organisms, they should report them in time.


    However, with the beginning of the experiment, thunderstorms did hit down, and alien creatures also had riots, but the "big changes" explained by the superior never appeared, or there were signs of occurrence.


    The thunderstorm was violent, but it also seemed to reach a limit, maintained at a peak and began to decline.


    But the extraterrestrial creatures on the ground are still just riots. It seems that thunderstorms have not had much impact on them.


    This naturally does not meet the expectations of the test.


    At this time, whether it is the front observation post or ordinary soldiers, or the scientific researchers in the rear or the generals in the headquarters, the mood is looking forward to and worried.


    They expect that this experiment will bring surprising results, but this result has not appeared yet, which makes people worry about whether this experiment can really achieve the expected results, or just so.


    However, no matter how strong this expectation and worry is, the objective physical phenomenon will not change with human subjective will.


    The thunderstorm triggered by the weather controller has reached the maximum, and the EMP impact caused by it has indeed affected alien organisms, and even the communication between the front position and the rear has been disturbed and affected to a certain extent.


    But all this is the limit.


    "Damn it, is it over?" looking at the thunderstorm that seems to be slowing down gradually, Chen Xin, who has come outside, held up his telescope and looked at the lightning twinkling sky in the distance, couldn''t help scolding.


    The physicist who came out to watch with him regretfully put down his telescope, sighed and said: "it seems that the EMP impact caused by thunderstorm is not strong enough! The released energy can not reach the degree of our expected impact on alien organisms!"


    "It''s a pity, but it''s good to prove that the EMP impact produced by thunderstorms is still effective, which at least points out the direction for us. Next, as long as we develop methods that can produce strong enough EMP impact, they can be used to deal with alien creatures!" although Chen Xin was disappointed with this experiment, he still said some encouraging words.


    After all, as a leader and core figure at the moment, if he looks lost and depressed, it will undoubtedly have a great impact and blow on the morale of others.


    Therefore, he must cheer up. Even if the test does not meet expectations, he must show that he is confident and everything is under control.


    "Well, indeed, although the experiment did not achieve the expected effect, it at least pointed out the right direction for us. As long as we study in this area, we will succeed!" physicists were encouraged by Chen Xin and boosted their spirit again.


    However, when they encouraged each other and began to discuss how to continue the experiment in the next step, a staff officer suddenly rushed over and shouted to Chen Xin: "academician Chen, we have received information. There is an emergency!"


    "Emergency?" as soon as Chen Xin heard this, his face suddenly changed. He hurried back to the headquarters behind the staff officer, and the physicist behind him hurriedly followed up.


    Returning to the headquarters, Chen Xin asked the staff what was going on while walking to the command desk.


    "It''s not the battlefield, it''s the weather." the staff explained to Chen Xin: "just now the comrades of the meteorological monitoring department sent a message that a cold wave heading south was affected by our experiment, and its movement speed was accelerated. It is expected to arrive in the Dongting Lake area within four hours, which will have an unpredictable impact on the whole battlefield."


    "Cold wave?" Chen Xin was surprised.


    He paid special attention to these information before the experiment. Although he knew that a cold wave would go south, according to the notification of the meteorological department at that time, the experiment should not affect the cold wave.


    According to the data given by the meteorological department at that time, the cold wave should not reach the Dongting Lake area until tomorrow after their experiment.


    But as it is now, in four hours, the cold wave forward will affect the front line soon.


    After all, the whole defense line is around Dongting Lake, not only the south, but also the north. They will be affected first.


    "Academician Chen, do you think whether to terminate the experiment?" the general asked Chen Xin.


    Although the experiment did not achieve the expected results, the originally planned experimental time did not come, and the general was not sure whether to continue the experiment, which required Chen Xin to make judgment and decision.


    Chen Xin hesitated, frowned and thought for a while before saying, "stop the test. We don''t know what results will be caused by thunderstorm and cold wave. If it has a serious impact and affects the defense line, it''s bad, so stop the test!"


    "Yes!" the staff on one side quickly responded and went to convey the order to stop the test to the relevant units.


    Looking at the staff to convey the order, Chen Xin thought and said to the general: "this is the first cold wave of this year. Before, the meteorological department predicted that there will be a significant cooling, so that the soldiers on the front line can seize the time to prepare for resisting the cold wave. At the same time, we should also be careful whether alien creatures will attack us through the impact of the cold wave!


    After all, their body temperature is more than 70 degrees, and the limit can reach more than 100 degrees. Even if the cold wave brings a significant cooling, it should not have much impact on them, so we must let the front line pay attention to this! "


    "I understand. When we knew there was a cold wave going south, we had prepared the front-line soldiers to resist the cold wave, and the relevant equipment to resist the cold wave had been sent." the general nodded to Chen Xin, indicating that they were ready.

 Chapter 708

    The cold wave has long been common to mankind. Even now, after the whole world has been frozen, the cold wave will occur several times a year in recent years.


    Although the arrival of each cold wave will lower the already low temperature again, even close to the limit of minus 100 degrees, for Yanguo, in addition to being in a hurry for the first time, after several times, the cold wave is the same for Yanguo.


    After all, with the help of Chen Xin, a person who opened and hung the energy tower, the black technology heating equipment makes Yanguo not worry about the impact of the cold wave.


    Especially when the snow is getting thicker and cannot melt because of the cold weather, they even isolate the colder temperature of the outside world to some extent.


    This is somewhat similar to the Inuit igloo. As long as the internal temperature is maintained and the heat is not lost, for humans, the cold wave is just a short-term bad weather that can''t go out and must stay indoors.


    However, this cold wave is somewhat different.


    Not only did the cold wave move southward faster than expected, but also because the previous thunderstorm test formed a storm in the Dongting Lake area.


    Thunderstorm itself belongs to a kind of extremely bad weather. Thunderstorm produced by weather controller also accumulates energy in the air by means of local heating, and then releases positive and negative charges by guiding air friction.


    According to the original plan of Chen Xin, meteorologists and physicists, thunderstorms should dissipate naturally after the test is suspended, and will not bring subsequent adverse effects.


    Even if the temperature rise in some areas will have some impact on the weather, it will not be very serious.


    However, when the cold wave heading south suddenly accelerates and will reach the Dongting Lake area within a few hours, everything becomes different.


    As we all know, when cold air and hot air meet, various weather phenomena will occur under the alternation of cold and hot.


    One of the manifestations is that the air pressure decreases rapidly in a short time, resulting in drastic changes in the weather.


    This phenomenon is called Bomb cyclone, which is usually seen in North America. The cause is that the warm and humid air meets the cold air, causing a rapid drop in air pressure in a short time, resulting in extreme weather.


    In the famous disaster film the day after tomorrow, such a scene also appears.


    A huge hole is formed in the clouds, just like a typhoon eye. The colder air in the upper atmosphere is sucked to the ground because of the rapid decline of air pressure, and everything is frozen in an instant.


    Now, as the cold wave heading south meets the warm air over the East Dongting Lake area caused by thunderstorms, an extremely violent bomb cyclone is forming.


    Even the most experienced meteorologists cannot predict what terrible damage this low-pressure system will bring. After all, mankind has never seen what will happen when cold air close to minus 100 degrees meets hot air of more than a dozen degrees.


    Since the birth of mankind and the formation of civilization, the entire Blue Star atmospheric circulation system has actually been relatively stable.


    Although there will be some bad weather, it has not produced too extreme weather phenomena.


    But this time, mankind will see what may be the most terrible weather phenomenon in human history.


    Because it''s dawn.


    "With the formation of this low pressure system, a large amount of high-rise air is sucked to the ground. This gradually formed pressure system is now like a huge vacuum cleaner to wash the air in the sky and the dust and particles in the air." the meteorologist pointed to the picture taken on the big screen and explained to the people around him: "Because these dust and particles are absorbed to the ground, the originally blocked sunlight loses its obstruction, and naturally it can shine on the ground."


    "The thunderstorm test artificially created a heating mass in the air. With the stop of the test, the heating mass lost energy supplement. Coupled with the cold wave and cold air going south, the temperature began to decrease rapidly, resulting in the air flow from top to bottom, so this low-pressure system was formed. Am I right?" After listening to the physicist, Chen Xin asked him the reason for the formation of this low-pressure system.


    The meteorologist nodded and still didn''t forget to add: "the principle is true, but this time the low-pressure system formed too fast! And the cooling range is too large, so it can cause such a terrible phenomenon."


    As he spoke, he did not forget to look at the gradually forming and brighter hole on the big screen.


    The picture on the big screen was taken in the eyes of the wind formed by the low-pressure system. Here, a thick layer of dust has fallen on the ground, which has become gray black under the long lost sunlight, and the sky is gradually changing from dim yellow to clear.


    Although it was a rare blue sky and sunshine, none of the people present had a smile on their face or felt happy about it.


    Because all this happened in just half an hour, and with the formation of the cyclone, the cold visible to the naked eye is coming.


    In the cyclone shrouded area, as the upper atmosphere is gradually sucked down to the ground, the ambient temperature is also decreasing sharply, because a layer of frost is rapidly forming on the gray black ground where dust falls.


    Although the picture on the big screen shows a calm and calm, it seems that even a leaf will not be blown up.


    But everyone looking at the big screen knows that this is only the center of the cyclone, similar to the existence of the typhoon eye. The faster it forms, the stronger the wind outside.


    For human beings, we have never observed what happens when the air of minus 100 degrees meets the air of above zero temperature.


    However, according to the meteorological data currently available to mankind, the faster the temperature decreases and the faster the cyclone forms, the more violent the storm brought by the low-pressure system. Obviously, an unprecedented violent storm is gradually taking shape.


    "Have all the soldiers on the defense line done their protective work? The storm may be more violent than we thought, so we must do a good job in response." looking at the blue sky we haven''t seen for several years, Chen Xin''s face is about to drip water, and asks the general on one side.


    At this time, the general was also very serious and said, "the soldiers on the front line have received orders, and everyone is ready to deal with extreme weather and all kinds of emergencies. I believe our soldiers can deal with such weather."


    "That''s good, but we still need to remind the soldiers that alien creatures may take this opportunity to launch a large-scale attack." Chen Xin reminded with worry: "humans can''t resist this bad weather, but those alien creatures may not be!"

 Chapter 709

    Chen Xin doesn''t know whether extraterrestrial creatures can resist the sharp cooling and strong winds brought by bomb cyclones, but it is obvious that such bad weather is not bearable by humans.


    Even though grass-roots soldiers have popularized protective clothing and exoskeletons, even if the protective clothing can withstand the extreme cold of more than minus 100 degrees, the frozen exoskeletons will still fix people into ice sculptures.


    In this weather, no one dares to stay outdoors. If you lie on the ground, even the whole person will be frozen on the ground.


    The military can''t help but rejoice at this time. It was lucky to upgrade the defense line to YONGGU fortification. Otherwise, there would be no place for the soldiers to escape.


    Although it is true that shrinking the soldiers into the bunker will affect the defense against alien creatures, at this moment, we can''t care about the risk that the defense line may be broken, and we can''t let the soldiers be frozen on the position directly.


    Fortunately, the bunker is equipped with defensive machine guns. After forming cross fire coverage, it can also resist the attack of alien creatures.


    In addition, alien creatures seem to be aware of the threat brought by this terrible weather. The offensive has slowed down a lot, and even tends to retreat and shrink their forces gradually.


    In the tension and waiting between humans and alien creatures, the storm finally came.


    The cyclone driven by the southward cold wave was very close to the East Dongting Lake area and soon reached the East Dongting Lake area.


    The soldiers stationed in the bunker can clearly see that with the arrival of the storm and the sudden drop of temperature, frost flowers began to condense on the walls of the bunker, and quickly spread to the whole wall.


    Even if there are heating facilities in the room, the temperature is falling quickly. The heat provided by heating equipment can play little role in such a rapid cooling.


    However, this is only the beginning. In the areas where the storm has passed, there are heating pipelines and equipment that have been frozen cracked and blasted due to the sudden drop in temperature, and even an energy tower has failed due to the sudden drop in temperature.


    Human beings rely on science and technology to deal with this is still so difficult, and the alien creatures that only have the body to deal with are naturally not much better.


    Although Chen Xin was worried that the sudden storm and cooling would not have any impact on alien organisms, after all, their body temperature is more than 70 degrees, which is more suitable for survival in a cold environment.


    But even so, these alien creatures are difficult to resist extreme cold as low as more than 100 degrees below zero.


    Although their chitin exoskeleton can effectively prevent heat loss and preserve their body temperature, the body temperature of more than 70 degrees is also enough to resist the severe cold and keep them warm.


    But that doesn''t mean they can resist the extreme cold of more than 100 degrees below zero.


    On the observation post of a human bunker, an observer clearly saw through a telescope that a combat daughter was frozen in the wind and snow, and then quickly turned into an ice sculpture.


    Although these aliens can survive in low temperature, their chitin exoskeletons not only prevent heat loss, but also cause the fact that their body surface temperature is also very low.


    This also makes them easy to be frozen. After all, the body surface temperature is too low, and quick freezing doesn''t need to cool down.


    "Is this too exaggerated? Are these alien creatures frozen to death?" looking at the alien creatures frozen into ice sculptures outside for almost an instant, the shivering observer asked his comrades in arms.


    At this time, the heating function of his protective clothing has been turned on to the maximum, and the heating facilities in the bunker are the same, but at this moment, the soldiers in the bunker still feel colder and colder.


    Many people have a layer of frost on their bodies, especially on the surface of exoskeletons. Even if they are wiped by hand, it is difficult to erase the frost on them.


    The helmet and mask covering the head are the hardest hit areas. It is even necessary to turn on the deicing function of the mask to remove the thicker and thicker frost on the mask. However, even so, most people still have a thick layer of frost on the mask.


    The low temperature made everyone in the bunker shiver. Many people even stamped their feet in place to try to warm themselves, but it didn''t play any role.


    Even if the heating equipment in the bunker is trying to release heat, and even has been turned on to the maximum, it still can''t make people feel a trace of warmth.


    Even if these soldiers stay next to the heating equipment, they still can''t reduce the chill on their bodies.


    At this time, the soldiers who still stick to the combat post bear even more cold, because they must stay next to the shooting hole where they can shoot, which is connected with the outside world, and the cold will directly erode their bodies.


    In fact, the two hands of the shooter on the defensive machine gun have been frozen on the handle of the machine gun and can''t be taken off.


    Although his hands are covered with thick gloves, and the gloves and protective clothing are integrated with their own heating function, the shooter still feels that his two hands have lost consciousness, which makes him very worried about whether he can press the shooting button when he needs to fire.


    If those alien creatures outside were not frozen, the human defense line at this time could not resist the attack of alien creatures.


    Such a cold temperature can no longer be maintained by will.


    The commander in the bunker himself was also very cold, but at this time he still insisted on standing at the observation port, looking out with a telescope and constantly monitoring the situation of alien creatures.


    However, his telescope was frozen, and the lens could not withstand such a low temperature and cracked.


    Looking at the frozen telescope lens in his hand, the commander also had to give up the idea of continuing observation and shouted to the soldiers in the bunker: "remove the people next to the shooting port, keep a distance from the shooting port, close the bunker! Only keep the observation port!"


    Hearing the commander''s order, the soldiers hurried away from the Bunker''s firing port and found something to plug the holes that introduced the cold into the bunker.


    Many soldiers were frozen and had to rely on the help of others to be dragged away from their original position.


    The commander looked at what the soldiers used to block the shooting port was frozen almost in an instant. His face became very grim. It was obvious that such a low temperature had seriously affected the operation.


    While commanding the soldiers to move the frozen people to the heating equipment in the hope that the heaters that have almost no effect can bring them a little heat, the commander is also preparing to ask for help from the rear.


    In such a situation, if we continue to let the soldiers stay here, it will really freeze to death.

 Chapter 710

    The terrible cold continued, but the war came to a standstill because of the sudden cold.


    Although the overall strength of both humans and alien creatures has not been affected by the cold wave and storm, it is clear that neither side can launch any offensive at this time.


    Because the terrible force 14 strong wind, accompanied by a low temperature of more than 100 degrees below zero, is enough to tear any creature or anything that dares to rise on the surface at this time.


    In fact, in such a terrible cold and strong wind, even the mobile base seems a bit shaky, so we have to find a shelter that can avoid the strong wind to avoid being damaged by the strong wind.


    As for alien creatures, they are more miserable than humans.


    Perhaps the nests deep underground are not afraid of such strong winds and cold, but these offensive forces on the surface can not resist the terrible wind of force 14 and the low temperature of more than 100 degrees below zero that can instantly freeze and crisp steel.


    After a large number of combat daughters and worker ant daughters were frozen at low temperature, they were directly blown away by the strong wind and torn to pieces by the strong wind.


    For a while, the whole battlefield in the East Dongting Lake area was one of the alien creatures.


    However, humans cannot be happy with this situation, because while alien creatures bear all this, humans are the same.


    Although humans can rely on bunkers, heating facilities and other construction facilities to resist the cold erosion, humans also have no ability to fight back.


    Even with protective clothing protection, the cold resistance limit of ordinary civil protective clothing design is minus 115 degrees. At this time, the external ambient temperature has approached this extreme value, and the local temperature is even lower than this.


    Even the lucians who had been living in the cold zone before were already too cold to stand. They relied entirely on the traditional Lucian heating method of vodka to ensure that they would not freeze to death.


    As for vehicles and aircraft? Sorry, they can''t even start. Even electric vehicles can''t be used at this time. The whole is frozen. Even if electric deicing is started, obviously these deicing devices are not designed to operate at a low temperature of more than 100 degrees below zero.


    Under the power of nature, everything seemed to be frozen and fell into stagnation.


    "This storm came at a bad time! I knew it would not be so urgent to carry out thunderstorm test. It would be good to press it for a period of time until the cold wave passes!" in the Dome City, Chen Xin returned home for a long time, but he was helpless complaining.


    "This is also a helpless thing, isn''t it? Who could have thought that it would develop into such a terrible storm?" Qin LAN comforted Chen Xin.


    The attack of the storm made her Titan army unable to fight. The army had no intention to confine everyone to the battlefield and transferred the body and driver to a place where they could avoid the cold and storm.


    After all, in this case, leaving the body and driver on the battlefield is just freezing the body and driver. In order to protect these precious bodies, it is necessary to take cold protection measures for them.


    Qin LAN naturally gets some free time and can go home to rest like Chen Xin.


    After all, although she is a Titan pilot, she is not a professional soldier and does not need to be so strict in discipline.


    Mo Qingyan poured three cups of hot water and handed them: "drink some hot water. It''s cold like this. Warm up and don''t get cold."


    Chen Xin took the water cup, touched the hot cup and felt the temperature in the palm of his hand. He couldn''t help sighing: "I don''t know how the soldiers on the front line are doing? They have been nailed to the defense line. I''m afraid it''s hard enough."


    "It''s really hard enough. The temperature in our room is almost below zero. We can imagine what the situation is in the front line." Mo Qingyan also looked with emotion. While wrapping her quilt tightly, she shrank on the sofa.


    In their Dome City, the external dome has been completely completed, and the energy tower and geothermal heating system have been completed. Therefore, under normal circumstances, when the external temperature is about minus 70 degrees, the temperature inside the dome can still be maintained at 10 ¡æ - 12 ¡æ, so as to ensure the survival of plants inside the dome.


    The indoor temperature is basically 20 ¡æ, which is not too cold, but it will not waste energy because the temperature is too high.


    However, now, the ambient temperature inside the dome has dropped to more than ten degrees below zero, and the indoor temperature has gradually approached below zero. We can imagine how cold it is outside.


    "Ah Xin, how long will this storm last?" Qin LAN looked at Chen Xin and asked him.


    Although I like the feeling of three people sitting together and chatting for a long time, everyone is worried at this time. Qin LAN naturally cares more about when the sudden storm can pass and let everything return to normal.


    "I don''t know. No one has seen such a big storm, and I can''t tell when it will dissipate." Chen Xin shook his head slightly and sighed before explaining: "Now that there are no meteorological satellites, our grasp and prediction of the weather have suddenly regressed for hundreds of years, and it is difficult to accurately judge the weather conditions. However, people from the meteorological department speculate that the bad weather may last for about a week, and the subsequent impact will not completely dissipate until a month."


    Hearing what Chen Xin said, Qin LAN and Mo Qingyan could not help looking ugly. It was obvious to them that such bad weather would last for another week, which would undoubtedly freeze to death.


    This also makes Mo Qingyan and Qin LAN think back to the first time when the disaster came and the first time when the temperature dropped.


    At that time, human beings, like now, were almost unable to resist the cold brought by the sudden drop in temperature. Many people fell ill and even froze to death.


    If it was as cold as it is now, I''m afraid no one could survive?


    After all, at that time, human shelters were not designed to withstand the extreme cold of more than minus 100 degrees. Minus 40 or 50 degrees was the limit that shelters could withstand at that time.


    Thinking of this, Mo Qingyan couldn''t help looking at Chen Xin and said to him, "fortunately, ah Xin is here. If you hadn''t done this, I''m afraid we would have frozen to death by now?"


    "No, human beings are tenacious, and this degree of low temperature can not destroy human beings." speaking of this, Chen Xin showed a self mocking smile on his face: "and if it weren''t for me, there wouldn''t be such an extremely bad storm, wouldn''t there?"

 Chapter 711

    Although the storm has brought extreme cold, it is not to say that it is not good.


    At least with the formation of the storm, a large number of dust and particles in the air were adsorbed to the ground, the sky became clear, the blue sky was exposed for a long time, and the sun finally sprinkled on the ground again.


    Since the disaster, first the dust caused by meteorite impact, and then the volcanic ash emitted by the eruption of DOPA volcano, the whole sky has long been covered. Even after a few years, there is still no sunshine on the ground.


    The sky is always dark, as if the sun had already disappeared, and there will never be dawn and sunshine.


    However, when a violent storm is generated, like a huge vacuum cleaner, sucking down the suspended dust and particles from the sky with the cold air, the sky is exposed for a long time.


    The blue color is so clear that people can''t believe it.


    Because human beings have not seen the blue sky for a long time. For a long time, many people have forgotten that the sky is blue, the sun will rise, and the sun will shine on the earth again.


    After years of no sunshine, many people seem to have forgotten all this.


    However, when the sun really shines on the earth again, people suddenly realize that they have not forgotten all this, but they have not seen the sun for too long and can not see the hope of the sun rising again. Everyone has gradually buried the blue sky and sunshine deep in their memory.


    When the sun returns to the earth, as described in the fairy tale, people who have been tortured by darkness and suffering and have gradually forgotten what light is finally recall the feeling of the sun shining on them and the joy of running under the blue sky.


    Of course, before the storm stopped, no one dared to leave the shelter of the building and run in the strong wind of level 14 and the extreme cold of more than minus 100 degrees.


    It''s not looking for happiness, but looking for the quickest way to heaven.


    However, for humans who have not seen the sun for several years, even if they can only feel the feeling of sunlight shining again through the camera or a few observation ports indoors, it is still a rare experience that people flock to.


    In the bunker on the front line, the soldiers stationed have been rotated. The soldiers who have temporarily thickened and increased the heating effect have replaced the soldiers who have been frozen enough, so that they can go to the warmer place behind to repair and change their protective clothes at the same time.


    The first thing the soldiers in rotation did was to come to the observation ports that had not been blocked, look out excitedly, and look at the golden light reflected by the long lost sunshine on the ice surface of Dongting Lake.


    "How beautiful!" some soldiers couldn''t help sighing.


    Everything in front of us has been covered and frozen by ice and snow. We can''t see the traces of alien creatures, nor the dust and dust falling on the ground. Some are just a piece of white ice and snow shining golden in the sun.


    "Everyone, don''t look too long. It''s easy to get snow blindness. Just have a good look!" the commander didn''t stop the soldiers'' behavior, but reminded them not to stare at the snow for too long, so they would be blind.


    The soldiers obeyed the commander''s orders, and each gave his place to others after becoming addicted.


    This is to allow other comrades in arms to see the snow and ice in the sun, rather than worry about their own snow blindness.


    The storm has been expanding and continues to move towards the south of the country.


    Scientists tried to use satellite communication equipment to restore contact with satellites in outer space. Although they had little effect, they also obtained several satellite cloud images sent back by meteorological satellites.


    At the time of the meteorite impact, although the satellites in space suffered heavy losses, since the space station and the astronauts on it could survive, some satellites naturally survived.


    Relying on the surviving satellites and the satellite cloud images they sent back, mankind finally looked down on the earth from space again.


    At this time, the surface of the blue star is only gray black, and a thick layer of black cloud surrounds the whole planet.


    Only over Yanguo, there is a huge funnel-shaped hole, exposing the ground below, and the funnel is rotating, gathering the surrounding black clouds to the center, forming a huge vortex.


    Now this vortex has gradually covered the whole southern part of Yanguo, and is moving downward and southward.


    "According to the prediction of meteorologists, the storm will eventually arrive in Guangdong Province in a week, and then dissipate due to the rise of temperature." in the conference room, a staff member is briefing others: "And according to the prediction, after this storm absorbs the dust over China, it will greatly improve the current air quality over China. Even if the dust in other areas spreads later, it will no longer block the sun. Although it will get dark, it will not be dark again."


    "That means the long night is over?" hearing the staff say so, Chen Xin couldn''t help whispering, as if he couldn''t believe it.


    The staff nodded, with a trace of excitement and excitement, and answered positively: "yes, the long night has ended. Although the natural law of sunrise and sunset will be followed, the sun will rise as usual."


    "This is so happy!" Chen Xin could not help clenching his fist and restraining his emotions: "although the storm has caused great impact and loss to us, it can be regarded as inadvertently doing a good thing!"


    "Yes! When the sun comes out, the temperature will rise, the crops have light, and photovoltaic power generation can be used... Everything has changed!" another staff member participating in the meeting couldn''t help crying excitedly.


    Chen Xin can understand this excitement. Is he not excited himself?


    Human civilization is too dependent on the sun. Even if they haven''t seen the sun for too long in the long night of several years, the impact of the sun on human civilization has not disappeared or dissipated.


    Now the sun finally shines again, which is the best news and the most exciting thing for human beings who have experienced all this suffering.


    "Everything will be different, so we should make preparations to meet this difference!" Chen Xin said loudly to other excited people, and announced the new work plan at the same time: "Since there is no dust cover, we must first find ways to restore contact with satellites in space and rebuild satellite communication network and satellite positioning system, which will help us change the current situation.


    In addition, the amount of dust and particles in the air has decreased, and the obstacles restricting the flight of the aircraft have been eliminated. We want the aircraft to fly again... "

 Chapter 712

    When the storm stopped, a whole week had passed.


    Although this extremely cold storm, which can be attributed to man-made accidents, had a serious impact on the whole central and southern part of the country, when the storm subsided, there was a sky that could finally see the sun.


    When the sun rose as usual many years ago, everyone had a feeling of long absence.


    This is the same for Chen Xin. It is the first time he has seen the sun rise in recent years since the last time he watched the sun set when the meteorite hit.


    Originally, he thought he might never see the sun rise again in his life, but he didn''t expect that this time, the sun unexpectedly shone on the earth again.


    Can it be regarded as a blessing in disguise, or a blessing in disguise?


    Chen Xin doesn''t want to show joy and joy. After all, the previous storm was caused by him in a sense, and the losses can also be attributed to him to some extent.


    Although it is said that human beings have not suffered serious damage due to the promotion brought by science and technology, it can not be said that they have not suffered losses.


    In this case, others may be happy to cheer the long lost sunrise, but for Chen Xin, he needs to consider the handling of various problems after the storm.


    Of course, although these problems need Chen Xin to deal with, it is not true that he is the only one to deal with them.


    As the main area affected by the storm, the East Dongting Lake area suffered the most serious losses.


    Because it used to be a war zone here, and the main reason for the storm was the thunderstorm test carried out by Chen Xin at that time, which led to that when the storm formed, extreme cold and strong wind attacked, the whole East Dongting Lake area was still a fierce battlefield.


    Although the soldiers on the defense line were prepared in advance because of the timely notification, these defenses did not fully resist the invasion brought by the cold wave.


    A large number of soldiers were still frostbitten on the defense line, and many weapons and equipment were frozen on the battlefield. One bunker was attacked by corrosive vesicles before, and even the outer wall was frostbitten this time.


    What''s more, because the temperature is too low, the coverage area is too wide, so that the whole heating pipeline is frozen. Even one of the energy towers responsible for providing heat is frozen, and many of them fail.


    "At present, the areas affected by the storm include Hunan Province, Hubei Province, Jiangxi Province, Guangdong Province and Fujian Province, and other surrounding provinces, cities and regions are also affected to varying degrees..." a staff member is reporting the disaster caused by the storm.


    Chen Xin listened carefully. The staff said too much, and the disaster was far more serious than he expected. To sum up, there were only eight words: it spread widely and was devastated.


    The worst situation is not in the area of East Dongting Lake. Although it is the center of storm formation, the front line has indeed been greatly damaged and damaged because it has been fighting with alien creatures, but with early warning, although there is not enough time, protection work has been done.


    In addition, the military is mainly stationed, and the military is undoubtedly more efficient than local areas, so the situation is not particularly serious.


    But even so, there are still a large number of soldiers on the front line who are frostbitten and in urgent need of treatment, leading to the collapse of the medical system.


    However, the army can respond quickly, but local governments are not so efficient, and many prefecture level counties and cities have not withstood this degree of storm and extremely cold conditions, resulting in serious disasters.


    This has led to the severe test of the medical system in all provinces and cities in the south, just as when the first cold wave came, a large number of frostbite and complications almost crushed the medical system.


    The disaster situation this time is more serious than at the beginning. If Chen Xin had not added a lot of black technology to the country in recent years, many places would not be able to survive this storm.


    Even though many places struggled to survive by relying on the black technology provided by Chen Xin, the snow and ice rolled up by the storm and the dust from the sky still buried many shelters. After the disaster, the first thing to do in many places is to actively carry out self-help and dig themselves out from under the snow and ice.


    The scope of the storm was beyond imagination. After all, in the past, even if there were typhoons and storms, it could not cover the whole central and southern part of the country, or even spread all the way down to the southeast coast.


    Even if it is a super large typhoon rarely seen in history, it is difficult to spread to so many provinces and cities, and unlike now, the state can organize various forces to actively rescue.


    Under such circumstances, although the state is also actively providing disaster relief, the war in Dongting Lake area, land transportation isolated by ice and snow, and air transportation that has been affected by high-altitude air quality all restrict the speed and intensity of national disaster relief.


    In the face of this unprecedented super natural disaster, what we can do is to actively save ourselves first, and then consider helping others.


    "We have known the disaster situation in the rear. How is the situation on the front line?" the general, as the front-line commander, asked an officer attending the meeting.


    As a general and commander of the theater, although he also cares about the affected areas, there is still war ahead, and he can only focus his attention on the battlefield.


    "At present, the alien creatures on the front line did not attack. The storm also caused a great blow to them. A large number of combat daughters were torn up by the storm, and now they are unable to attack us." the officer reported to the general and explained: "The troops on the front line have been replaced. The soldiers with severe frostbite have been sent to the rear for treatment. Now the replaced troops are in good condition. They are repairing and maintaining the defense line. At the same time, they are actively preparing for war to ensure that we can block them even if alien creatures attack."


    Hearing what the officer said, everyone in the conference room looked a little better. This is one of the few good news after hearing so many bad news.


    "In addition to these, I think we also need to pay attention to the changes brought about by the rising sun." it was Chen Xin''s turn to speak, but he turned to the environment and weather: "Although the storm blew away the black clouds above our heads and made the sun reappear, it did not blow away the dust in the blue star atmosphere. We need to consider whether the sun comes out temporarily or for a long time.


    If it''s only a temporary light, it''s easy to say, but if it''s a long-term impact, many things need to be adjusted. "

 Chapter 713

    The black clouds in the sky were blown away, revealing the clear sky again, which is certainly a gratifying thing.


    But how long this will last, whether it is temporary or permanent, is an issue that policymakers must consider.


    If it is only a short light, and then the black clouds will cover the sky, there is nothing to say. It is rare. Now this short light is good, and there is no need to make too many adjustments and changes.


    But if this effect is permanent and mankind finally regains the sunshine after many years, many things will be changed.


    Not to mention anything else, with the return of sunlight, there will be great changes in the cultivation of crops.


    Now human beings rely on artificial light to maintain agricultural production, which needs to consume a lot of energy to provide light for crops.


    If the effect of natural light on crops can be restored, it will undoubtedly save a huge amount of energy, which can be used in other places and greatly improve the current situation faced by the country.


    Not to mention the impact of other means of using solar energy on the current situation faced by the country. After all, mankind has not evolved to get rid of the sun in terms of species or science and technology.


    We are born because of the energy of stars, and civilization is developed because of the light and heat from the sun. Everything of mankind is built under the sun.


    Regaining sunshine is of great significance to both the country and the whole mankind.


    The senior management also knows this and attaches great importance to it. All relevant departments are required to evaluate the current situation as much as possible to determine how long the sunshine will last.


    After the clouds dispersed, the space Department re contacted the surviving satellites in space. The meteorological department obtained quite valuable data and made analysis and prediction.


    The conclusion is that the sun will not continue, but it will not return to the night.


    The specific analysis results are quite complex. There is a thick pile of analysis reports obtained by Chen Xin alone.


    After reading it carefully, he input all the data into the virtual device simulated by nano molecules for calculation. The final conclusion let Chen Xin finally relax.


    According to the data obtained by the current meteorological department, most of the dust and particles over Yanguo have dissipated under the influence of the storm. The most thorough dissipation of dust clouds is the area passed by the storm center, that is, an arc from the East Dongting Lake area to the coastal zone of Guangdong Province.


    In addition to this area, because the scope of the storm is too wide, the dust clouds in surrounding provinces and cities also dissipate to varying degrees according to the distance from the storm center.


    It is possible to be close, that is, the degree of cloudy days with poor air quality at ordinary times. What is far away is about the appearance of severe haze days in the past, and what is farther away is sandstorm weather. Only the northwest and northeast border areas of Yanguo are too far away, with only a little light before dawn.


    This is undoubtedly good news for Yanguo.


    However, due to the air flow, the dust clouds that have not dissipated in the surrounding areas will still fill this cleared area.


    However, even if the dust cloud will return to the sky over the country, it will no longer form the previous thick that can block the sun and turn the day into night.


    According to the forecast of the meteorological department, most areas can maintain the existence of light in the future. Only those areas less affected by the storm may return to night in the future because the dust clouds do not dissipate enough.


    That''s good! After all, most areas of Yanguo will be able to get rid of the night and return to the day of alternating day and night.


    As a result of this prediction, the state has begun to adjust its strategy. Many plans and plans prepared long before the disaster have been turned over again. The high-level will formulate a new national policy according to the current situation.


    After all, for human beings, sunshine and no sunshine are really two different things.


    Thanks to the dust dissipation, the Aerospace Department has also reconnected with the satellite equipment still existing in space. It has not only restored many functions closely related to production and life, such as satellite communication, weather prediction and satellite positioning, but also prepared to launch new satellites to make up for the satellites lost due to meteorite impact, Rebuild the satellite network in space.


    The restoration of satellite communication has made the transmission of domestic information much smoother than before. Although the national defense and military communication network has always played an important role, there is always a gap in the convenience between telephone line and wireless communication.


    Although the complete recovery will take some time, even the recovery of the most basic communication network will enable the country to better and faster grasp the local situation, make more efficient targeted adjustments, and speed up the operation of the whole country.


    Several valuable military satellites are put into use again, which also allows mankind to overlook the overall situation and finally master the situation of the whole battlefield in real time.


    Overlooking from space, the situation of the whole battlefield was clearly presented to everyone for the first time, and the military can finally grasp the situation of the whole battlefield in a more timely manner, which also greatly enhanced the advantages of mankind in this war.


    It can be said that although the storm has seriously affected Yanguo, when the dust in the sky dissipates and many functions in the field of sunshine and aerospace are restored, it is indeed a blessing in disguise.


    Because of these restored things, the current situation in Yanguo is undoubtedly much better. The whole country is more closely linked again. Both the allocation of resources and production and life will be greatly affected by the dissipation of dust and the end of the long night.


    Chen Xin, who looked at all this from the deduction of virtual devices, also sincerely generated a kind of excitement and excitement, which is the hope for the future!


    This makes Chen Xin full of energy.


    Although they still have various difficulties to overcome, all these will be overcome.

 Chapter 714

    As the meteorological department confirmed that the sun would not be obscured again, each department began to adjust their next plans and arrangements.


    Agricultural production departments naturally think about how to reuse natural light without spending a lot of energy every day to provide artificial light.


    At the same time, they also plan to build a large greenhouse on the ground to make up for the loss of food production caused by the invasion of alien organisms.


    The military doesn''t care about this. Although there is no small impact on them, the war is still the same. When the sun shines, the impact on the military is the smallest.


    As for other departments, the meteorological department is probably the most influential and happy.


    Before this time, the meteorological department seemed to go back a hundred years ago in terms of meteorological monitoring and weather forecasting because of communication obstacles and the absence of satellite cloud images.


    They can only rely on local manual monitoring to determine the weather conditions, and then summarize these collected conditions, so that they can analyze the future meteorological trend and speculate on possible weather changes. The efficiency is quite low, and the accuracy of prediction is greatly reduced.


    If it weren''t for this reason, when Chen Xin wanted to conduct a thunderstorm test, they wouldn''t go south with the cold wave. They only reacted when they arrived at the test area in a few hours.


    Now they don''t have to worry about it. The restored satellite communication and meteorological satellite monitoring enable them to finally re monitor the weather in real time and accurately and effectively predict the future weather.


    Although it is still not as good as before the disaster, it has at least recovered to the level of the 1980s and 1990s.


    And with the satellite network supplement plan listed by the Aerospace Department, the number of satellites will be gradually restored to the level before the disaster in the future, which is naturally excellent for the meteorological department.


    For this reason, although the meteorological department has been busy, its morale is very high. A large number of sealed instruments and equipment have been put back into use. Meteorological analysts who were useless because of the loss of satellite cloud images have also vigorously recalled and re established the gas phase analysis and prediction department.


    Similarly, the space sector has regained its vitality and enthusiasm because it has regained a clear sky.


    As we all know, the launch of spacecraft needs good weather. It not only needs appropriate time for the spacecraft to orbit, but also needs good weather to avoid interfering with the launch of spacecraft.


    In the past, there was no way to launch a spacecraft under the weather conditions of dark clouds.


    Now the black clouds in the sky have dispersed, which undoubtedly gives the space Department a place to use again, rather than helping other departments in production and research.


    This has also led the space Department to formulate many ambitious plans, including the reconstruction of satellite positioning network, the re launch of meteorological satellites, the re search of existing on orbit satellites and the restoration of connections


    Even the space Department has reconvened previously trained astronauts for restorative training, so that these astronauts who thought they were no longer possible to go to heaven can be prepared to resume the use of the space station launched before the disaster.


    The aviation department is also planning to clean up the airports in major cities in China and restore the domestic aviation network.


    Although there are still planes available before, especially with the help of Chen Xin, the routes with Lucia have been reopened, the domestic air transportation is still relatively limited, that is, the military can still use it on a large scale. Civil aviation can basically be said to be completely stopped and transport a little scarce materials at most.


    However, now, with the restoration of meteorological conditions, the reopening of satellite and other facilities, the restoration of air navigation and control, the restoration of civil aviation and the expansion of military aviation have also become listed in the plan.


    In addition to these departments, other departments are also actively dealing with the changes caused by the re emergence of the sun.


    It can be said that with the return of the sun, the whole Yanguo is like a frozen person, glowing and moving again in the sunshine.


    However, although with the re illumination of the sun, the whole country is adjusting and intending to carry out large-scale reconstruction, the threat of alien organisms still forces the country to focus most of its energy on the war.


    Although various departments have formulated plans enthusiastically, most of the planning countries have only approved them without investing resources.


    It is not that the state does not want to start these plans and invest resources to vigorously resume construction, but now it must devote most of its resources to war.


    If the invasion of alien creatures is not blocked, it will be tantamount to another doomsday disaster for mankind.


    Under such circumstances, the state can only devote more resources to war rather than reconstruction.


    However, it may be a blessing in misfortune. After alien creatures suffered the attack of extremely cold storm and lost a large number of combat daughters, they may be replenishing the number of daughters during this period of time, or they may be affected too much. Until human beings re strengthened the defense line, and the impact of the storm completely subsided. After a month, alien creatures have not attacked again.


    If it were not for the recovered military satellites, they had begun to monitor the entire theater for 24 hours to make sure that alien creatures did not play the trick of hiding from other places, and the vibration monitoring devices installed on the defense line did not respond. The military even thought they were playing a surprise attack again.


    Thanks to the fact that aliens have not attacked this month, the military has strengthened the defense of the front line again, not only repaired the damaged parts in the storm, but also added more firepower points.


    After all, now that the sun shines, the line of sight becomes much wider, and the range of defense weapons can be better played. Naturally, the military has installed more defense weapons.


    Chen Xin is considering how to adjust the design of the dome city because of the influence of sunshine.


    Before, although the dome city also considered the illumination after the re emergence of the sun, so it made the dome itself semi transparent, but it was considered for more than ten years or decades. It never thought that it could restore the illumination now.


    For this reason, the construction work of the other two dome cities under construction has not resumed since the storm. The design department is working with Chen Xin to study how to readjust the design.


    In addition, the agricultural department also found Chen Xin, hoping to discuss with him how to transform the ecological greenhouse into a place where natural light can be used, so that Chen Xin was very busy for a while.


    However, in addition to these things, another thing also involves a large part of Chen Xin''s energy, that is, the country has received help from Europe, and alien creatures have appeared along the Mediterranean coast.

 Chapter 715

    Although it was really thought that extraterrestrial creatures should not only appear in Yanguo, not only in a place in the Dongting Lake area, Chen Xin and the national high-level did hold such expectations and ideas, hoping that extraterrestrial creatures would only appear in this place.


    Because if alien creatures also invade other parts of the country, the country will fall into an extremely passive situation of two-line combat.


    Fortunately, no trace of alien creatures was found in other places in Yanguo. It seems that they really only appeared in the Dongting Lake area and are now firmly blocked by the military defense line.


    But no one expected that alien creatures would appear in the Mediterranean.


    This is no better than that in the Dongting Lake area. The military of the Republic of China strictly prevents and guards against alien creatures.


    The whole Mediterranean area is very wide. Needless to say, there are dozens of surrounding countries, spanning three continents and connecting the two oceans, which can not be surrounded even before the disaster.


    Under such circumstances, it can be said that the invasion of alien creatures is almost unlimited. European countries are OK. At least they can resist and struggle, while African countries on the other side are completely pushed flat by alien creatures and let them ride the African continent.


    Before, although China and European countries had some contacts, they were only connected, with neither information exchange nor intelligence sharing.


    After all, the distance is too far away, and it is difficult for Yanguo to receive signals from European countries, so it is difficult to maintain smooth communication.


    If the storm had not blown away the dust clouds, the space Department would have reconnected with the communication satellites in the sky, and the signal receiving capacity would have been greatly strengthened. I''m afraid it would not be able to receive signals from European countries and understand that they have been ravaged by alien creatures at this time.


    Even Lucia was surprised at this. Although they were closer to Europe, their communication was completely cut off because Lucia had been unable to deal with European countries.


    It can be seen that Lucia asked for help from the burning country rather than from the European countries closer.


    Therefore, this time, European countries did not ask Lucia for help. In fact, they were not asking for help from Yanguo, they were just asking for help from neighbouring countries, but the help signal was received by Yanguo communication satellite, which was unexpectedly restored to use.


    Just for this matter, neither Yanguo nor Lucia can sit idly by.


    Although European countries are far away from Lucia and Yanguo, they did not ask for help from the two countries. The relationship between Lucia and Yanguo and European countries is not particularly good. The two countries do not know that there is no problem at all.


    However, alien creatures will not give preferential treatment to the two countries because they do not support European countries.


    On the contrary, once alien creatures destroy the resistance of European countries and completely invade the European continent, their next trend will undoubtedly be towards Lucia and Japan.


    At that time, Lucia and Lucia will face alien creatures who have completely mastered the two continents of Africa and Europe. At that time, even if the strength of Lucia and Lucia is strong, it is estimated that it will be difficult to resist the attack of alien creatures.


    Therefore, it is a very inevitable thing to support European countries at this time, so that they can continue to support and block alien creatures in Europe, rather than allowing them to continue to invade or even spread to inflammatory countries.


    In fact, the senior leaders of Yanguo do not want to make this decision. After all, there is already a war zone in China. Just supporting the war in Dongting Lake area has made Yanguo need to deal with it with the strength of the whole country. Now they have to support Europe, which really makes Yanguo a little stretched.


    However, if alien creatures really destroy European countries and occupy Europe, the consequences will also be unbearable.


    Therefore, after communicating with Lucia, the two countries decided to provide assistance and military support to European countries.


    But how to support, the two countries have fallen into embarrassment and differences.


    For Lucia, they have just recovered a little strength in their country to support Yanguo. It is because Yanguo has supported them before. Based on the idea of helping each other and the fear that Yanguo can''t carry it, Lucia sent troops to support them.


    Although more reinforcements are still being formed in Lucia, it is only an army.


    According to Lucia''s original plan, these reinforcements will be sent to Yanguo after the formation and training, and their equipment will be provided by Yanguo.


    After all, Lucia can''t produce the set of equipment that can fight alien creatures in Yanguo.


    As for the Yanguo side, although it has retained strong strength in terms of population, industrial production capacity, military and scientific and technological forces, when there is a theater to be maintained in its own country, most of the troops of the Yanguo military can only invest in its own battlefield first, rather than supporting Europe.


    Therefore, after many consultations, the two countries finally decided to form a joint force to support Europe, but the force will not be too many, and it is mainly composed of lucians, and the inflammatory country is responsible for providing the equipment of the support force.


    After they went to Europe, their main task was not to fight, but to make European countries have the ability to fight alien creatures as much as possible.


    After all, the ability of the two countries is limited, and the military forces that can send in the past can not afford to fight with alien creatures.


    To accomplish this task, a reliable logistics support base is undoubtedly what the reinforcements need most.


    Fortunately, the military had previously proposed the need for a larger mobile base. Chen Xin has completed the planning and design of the land aircraft carrier and handed it over to the relevant departments for further detailed design.


    Now after a month, the drawings have returned to Chen Xin.


    However, because only domestic use was considered at that time, the moving speed of the land aircraft carrier was not fast, and the traffic capacity was limited. It was only considered as the strategic support point of the defense line.


    Now to support the European battlefield, after serious thinking, Chen Xin thinks it''s time to have some real black technology.


    After all, the speed of mobile base is slow enough. If it runs too slow, it will not be practical to support the European battlefield.


    Therefore, after careful consideration, Chen Xin decided to add flight capability to the land aircraft carrier.


    This was something he had considered when designing the mobile base. At that time, it was also to enable the mobile base to deploy rapidly. However, later, with the manufacture of helicopters with large capacity, the mobile base can be suspended by helicopters for rapid deployment, so he did not deepen the design in this regard.


    But now, obviously, it''s time to take out this design again.

 Chapter 716

    In fact, from a practical point of view, the most appropriate way to quickly reinforce the European battlefield should be the air bag ark used by Chen Xin in disaster relief and support to Lucia in the southwest.


    This large airship has good carrying capacity and sufficient self-sustaining capacity after transformation.


    The good performance of this air bag ark has been proved in Lucia''s support operations before. If the country wants to support the European battlefield immediately, it should actually use the air bag ark instead of waiting for Chen Xin to build the land aircraft carrier.


    In fact, the original plan of the military and the national high-level to reinforce the European battlefield was to wait for Lucia to form an army, and Yanguo used trains to transport the troops sent by Yanguo and the equipment provided to Lucia to Lucia, and then enter the European region by railway from Lucia.


    However, although this plan can support the European battlefield, it is unlikely that European countries can effectively resist the attack of alien creatures.


    Although he doesn''t know what the alien creatures on the European battlefield look like, Chen Xin clearly knows that even if they are only as strong as the Dongting Lake area, they are still not able to resist the armies of European countries that have not been driven by their own plug-in.


    In such a situation, if a force that can effectively resist the attack of alien creatures is reinforced on the battlefield, do European countries use their own forces to resist the attack of alien creatures and rely on this force to eliminate alien creatures?


    Or will this detachment top up and fight with alien creatures to consume, and their own troops take this to preserve their strength?


    The answer is something that doesn''t need to be thought about at all, especially in those European countries.


    One likes to surrender, one likes to sell his teammates, one likes to pit his teammates, and the other can fight. He was beaten down decades ago, and now he has become a mess.


    Although these countries have undergone a round of integration in the previous disasters, their strength is still good, and there is no surrender in fighting with aliens. It is reasonable that there should be no moths.


    However, the past historical records of these European countries are not very good. Chen Xin doesn''t want his soldiers to be cheated by these guys.


    If we can make the soldiers of these countries play a more effective role, we can at least make them less excuses to entrap people.


    Therefore, considering maintaining the European front and making this support to the European battlefield more effective, Chen Xin feels that it is very necessary to provide a land aircraft carrier for the reinforcements.


    If we follow the normal process, it may take at least a few years to produce a land aircraft carrier. Whether it is the final design or the actual construction, it requires a lot of time and resources.


    But now Chen Xin is ready to speed up the process, and everything will be much faster.


    First of all, it is the drawings. The drawings previously required by various departments to cooperate with the design are summarized again. Chen Xin did not look at each drawing carefully, but gathered them all into the computer to generate a three-dimensional model and combined them together.


    Because the design framework is fixed in advance, all the designs are based on the conceptual design drawings given by Chen Xin. In addition, various departments can coordinate directly, so the design drawings gathered by various parts naturally do not have any size gap or design mismatch, and soon assembled into a three-dimensional model of a land aircraft carrier.


    Chen Xin imported the data into his watch and re projected it with nano molecules, ready to adjust the details.


    This is only the first draft design proposed according to the original frame design drawing. Many parts are simply conceptual design. There is only a description and size to show that there is such a thing here. When it is finally implemented on the drawings really used for production, it will be changed long ago.


    Even after it is implemented on the drawings, various modifications and adjustments will be made in the actual construction process.


    Therefore, large vehicles such as land aircraft carriers need to modify and adjust the drawings countless times in the whole construction process, which will even run through the whole construction process.


    But now Chen Xin obviously doesn''t want to take his time. He directly upgraded the system to the drawings.


    This is a very simple thing for Chen Xin now, and after his upgrading and adjustment, the drawings of the land aircraft carrier have been upgraded to a satisfactory level.


    But this drawing is just Chen Xin''s idea. If it is, he will submit the drawing to other departments for modification and improvement, integrate their opinions and adjust the unreasonable places.


    Now, however, Chen Xin has just upgraded and adjusted the drawings of the land aircraft carrier based on the experience accumulated in the previous mobile base, and has directly finalized it.


    In order to save time, he does not intend to take this drawing for modification and adjustment. Instead, he intends to get the finished products out first, and then slowly map the drawings and push back the technology, just as when the mobile base was built.


    And most importantly, in order to enable the land-based aircraft carrier to reach the European battlefield in the shortest time, Chen Xin designed the real black technology equipment - anti gravity device on the land-based aircraft carrier.


    At first glance, the existence of anti gravity device sounds very outrageous, but in fact, so far, humans still have a certain theoretical basis to realize this technology.


    For example, superconductors still in the laboratory stage and maglev, which can be applied in practice, can actually be regarded as anti gravity in a sense.


    The essence of anti gravity is to counteract the binding of gravity on the object, so that the object can be suspended in the air.


    After achieving this, only a small thrust is needed to make the object "fly" in another form.


    This is essentially the same as the traditional flight technology, which offsets the gravity through the air lift to make the aircraft fly in the sky. It offsets the constraints of gravity on the object in some way to make it leave the ground.


    Of course, although the basic principle is very simple, it is very difficult to realize it. Although it has a theoretical basis and ideas, it is almost impossible to realize it.


    But for Chen Xin, as long as he has ideas, the rest can be handed over to the system upgrade, which is nothing more than survival. For him now, after his survival has broken through the eight digits, he has not paid much attention to how many survival points he has.


    After all, he uses less survival points now. Unless he plans to hit a land aircraft carrier directly with survival points like this, it will only be a small fuss about upgrading drawings, which really won''t cost much.

 Chapter 717

    With the drawings, all that remains is to build the land aircraft carrier.


    However, if countries organize production according to the drawings, it will undoubtedly take a long time to complete.


    After all, to build such a big thing, the production of supporting parts, from the main steel plate to a screw, all need supporting factories for production, and then they can be summarized step by step and finally assembled into a land aircraft carrier.


    However, according to Chen Xin''s plan and ideas, it is obvious that we can''t wait so long, especially for the anti gravity device. Although we can certainly process it according to the drawing with the drawing, how long it takes for this processing time and how long it takes for humans to master the manufacturing technology are endless.


    Therefore, in order to avoid wasting time and save unnecessary steps, Chen Xin directly asked for a new production mobile base from the state.


    This is a mobile base that the country has been manufacturing before, but the production progress of this one is slower and has only been completed recently.


    Originally, this one was also to be put into the front line against alien creatures. Together with the other four mobile bases that have formed a defense network, it has become a new battlefield support node.


    However, Chen Xin''s side has a need, and the senior management and the military still did not hesitate to allocate it directly to Chen Xin''s side.


    After getting the new mobile base, Chen Xin was not polite and began to upgrade it.


    Because the drawing itself is changed from the mobile base, the upgrade consumption of land aircraft carrier is lower than Chen Xin expected. Of course, it has a lot to do with Chen Xin''s failure to make major changes.


    Chen Xin did not upgrade his mobile base into a land-based aircraft carrier once, or upgrade the land-based aircraft carrier to what he designed.


    Of course, this does not mean that the system cannot be upgraded at one time, but Chen Xin has other plans.


    After the upgrade, Chen Xin found the military and asked them to equip the so-called "temporarily transformed" land aircraft carrier with crew.


    After all, unless Chen Xin upgrades the land aircraft carrier to a fully automated level where one person can drive, it is by no means possible for a few people to drive such a large land vehicle.


    In fact, even the mobile base needs at least dozens of professionals in various positions to fully operate.


    This is the result of many times of transformation and optimization of the mobile base after Chen Xin, and it was not unique to everyone in the suvia period.


    Therefore, although the land aircraft carrier comparable to an aircraft carrier is not so large in terms of volume, the internal complexity and the number of operators required are not discounted at all.


    In addition, Chen Xin also plans to upgrade it to a type of floating flight with anti gravity equipment, which requires more operators.


    After receiving Chen Xin''s request, the military was immediately surprised. They really didn''t expect Chen Xin to build a land aircraft carrier in such a short time.


    Even if he used the existing mobile base for transformation, the speed was incredible.


    However, Tuo Chen Xin often made such big news before. The military was only surprised and had no other ideas. He soon allocated the personnel he needed and the crew needed for a land aircraft carrier.


    "I won''t say any polite words. Your next task is to familiarize yourself with the land aircraft carrier in the shortest possible time, strive to form combat effectiveness as soon as possible, and be able to drive it and use it." facing the people transferred by the military, Chen Xin was not polite, but emphasized his requirements to them.


    Among the people transferred by the military, the captain is a naval colonel. As senior technical talents, although naval ships are no longer available, they are still not wasted or idle.


    But before they were assigned to other posts, they received strict training while maintaining their original professional skills.


    Now facing Chen Xin''s explanation, the captain replied calmly: "Academician Chen, please rest assured that we will be familiar with and master the land aircraft carrier in the shortest time, and we will certainly form combat effectiveness in the shortest time! Moreover, among these people transferred by the military, there are many people who have served on the mobile base before, and some people who have served on the aircraft carrier before. There will be no problem in mastering the land aircraft carrier within three months Yes. "


    "I have confidence in your determination, but although this land aircraft carrier adopts a design similar to the original mobile base, there are still adjustments and changes in many places. There are no instructions for you to see these places, so everything depends on you. The task is very arduous." Chen Xin''s words don''t have any moisture. The system is upgraded. All kinds of problems will be solved by black technology, but there will be no instructions and so on. Everything depends on your own exploration.


    So for those who came to take over the land aircraft carrier, their task is far more arduous than they thought.


    Moreover, Chen Xin did not forget to add: "according to my ideas and plans, you need to drive this land aircraft carrier to support the European battlefield. In order to facilitate your journey and improve the mobility of the land aircraft carrier, I will add a set of special equipment to this land aircraft carrier. You have a lot to master!"


    Hearing what Chen Xin said, the captain also felt the pressure, but he said calmly: "please rest assured, academician Chen, even if the task is arduous, we will ensure to complete the task! We promise to be familiar with and master the land aircraft carrier within three months!"


    "If you have this confidence, I''m relieved, but there''s one thing to explain. You don''t have three months, only one month. In one month, you''ll start on your back, arrive in Lucia, pick up the troops set up there to support the European battlefield, and then go to the European battlefield." when Chen Xin said this, his face was also a little embarrassed.


    Because it''s his idea to make all this happen, otherwise the support forces just need to go north by train.


    Also because of this, the personnel receiving the land aircraft carrier only have one month, plus the time to travel to Europe, so they can get familiar with and master the land aircraft carrier.


    Hearing what Chen Xin said, the captain''s face finally changed, but he nodded very seriously and promised Chen Xin: "time is tight and the task is heavy. We have long been mentally prepared. Please rest assured, academician. Even if all of us don''t sleep for a month, we will complete the task assigned by our superiors!"

 Chapter 718

    Although land aircraft carriers retain most of the functions of mobile bases, including bottom dock, upper hangar, medical facilities and so on, considering that they will fight for a long time in the European battlefield far away from local support, it is unknown whether those European countries will provide them with sufficient supplies and needs, Therefore, Chen Xin specially installed a special production line on the land aircraft carrier.


    "When you arrive in Europe, those European countries can provide supplies. If they can''t provide supplies, you have to take care of yourself." on the land aircraft carrier, Chen Xin took the captain deep into the interior of the ship and came to the cabin where the production line he installed is located: "This production line is the center of this land-based aircraft carrier. After you arrive in Europe, as long as you can obtain ore raw materials and put them here, you can smelt them into metal materials, and then generate the required parts or finished products through 3D printing technology. You can be competent either to supplement consumption or repair the ship body."


    "This is a good thing! Academician Chen, what can this set of equipment produce?" the captain suddenly brightened up after listening to Chen Xin''s introduction.


    As a captain, he certainly knows that logistics is what he plays in modern war. With such a set of equipment, he can get continuous supplies as long as he squats in a mining area. This is much more practical than other weapons and equipment.


    Chen Xin also installed this set of equipment out of the idea of ensuring their logistics supply in Europe.


    "It can produce everything," said Chen Xin. He took the captain into the cabin and came to the 3D printing equipment. He opened the above production list with his permission: "this equipment can produce all kinds of steel plates and replacement parts for repairing the hull, from soldiers'' exoskeletons, power armor and electromagnetic rifles to shipborne aircraft, tanks, armored vehicles and Titans.


    Even if necessary, you can rebuild a mobile base by producing parts and assembling them yourself, and even this version of land aircraft carrier can be built.


    When installing and designing it, I have calculated the dimensions of all parts. It can complete the production of all your weapons and vehicles, so that you won''t get into trouble because of the loss of weapons and equipment when necessary. "


    "That''s great!" the captain shouted to Chen Xin. He was surprised by the variety of materials that this 3D printing device can produce. He didn''t know what to say. He could only express his mood with exclamation.


    However, the captain also noticed a detail in Chen Xin''s words. In contact with the information mentioned in Chen Xin''s mission assignment, the captain asked him: "Academician Chen, you have been emphasizing that you will add a new set of equipment to the land aircraft carrier, saying that this 3D printing equipment can only build the current version of the land aircraft carrier, that is, we can''t use this 3D printing equipment to make the new equipment you add.


    What equipment are you going to install on this land aircraft carrier? What if the equipment breaks down and we can''t repair it? "


    Hearing the captain''s question, Chen Xin took a very vigilant look out and saw that there was no one outside. Then he whispered to the captain, "what I want to install on this land aircraft carrier is called an anti gravity device. After starting, this land aircraft carrier can become an air aircraft carrier with flying ability.


    However, at present, even I can only trial produce this device, which is still in the experimental stage, and the equipment itself is dangerous, so you can''t use this 3D printing equipment. There are no relevant drawings entered, and I don''t intend to let you manufacture it in Europe.


    After all, you know what the virtues of European countries are. Supporting them is only to enable them to maintain the front, so as not to let alien creatures break through Europe and then invade Asia along Eurasia and spread to China.


    Although I will install anti gravity devices on this land-based aircraft carrier in order to provide rapid support so that these Europeans will not be pierced by alien creatures, I must ensure that they will not leak out, and you must also ensure that this technology will not leak out. "


    Chen Xin''s words obviously can''t be put on the surface, but the captain can understand why Chen Xin did this and why he told him this.


    As the captain, he obviously will play an important role in the mission of supporting the European battlefield. Even when necessary, he is the person in charge of the mission. Therefore, as the captain of the land aircraft carrier, he must clarify the purpose and goal of the operation.


    What Chen Xin said is undoubtedly the deeper purpose of the country and the high-level decision to support the European battlefield, rather than what he said that for the sake of the community of common destiny of mankind, we can''t wait to die for the human countries in Europe.


    "I see. Academician Chen rest assured that I know what to do. We will ensure that China''s important science and technology will not leak out while completing the task." as a captain who can become a colonel in the Navy and has been selected to become a land aircraft carrier, the captain himself has rich experience in how to protect his country''s confidential technology from leakage.


    After all, the navy is a high-tech service, and there are quite a lot of confidential technologies on warships. There is no need to emphasize the confidentiality regulations.


    When Chen Xin heard the captain say this, he nodded slightly, but he also emphasized another thing: "protect important science and technology from leakage. This is just by the way. The focus of your task this time is to make the Europeans have the ability to resist alien invasion.


    I also discussed with the high-level and the military before. After discussion, the high-level and the military can provide simplified versions of technologies such as exoskeletons and electromagnetic rifles for front-line combat forces to face alien creatures.


    As for whether they will crack the technology or not, in the current situation of fighting against alien creatures, they don''t care so much about this little problem, but they can''t get a screw for equipment such as power armor and Titan! "


    In fact, countries like Titan and power armor do not say that they will not provide them to European countries at all. After all, they are also fighting against alien creatures like Yanguo, which can improve their combat effectiveness and help fight against alien creatures.


    It''s just that exoskeleton and electromagnetic rifle can provide simplified versions, which should be supported for the sake of the human community. However, equipment such as Titan and power armor need real gold and silver from European countries, which can be replaced by technologies that can make inflammatory countries feel excited.

 Chapter 719

    Chen Xin installed these powerful things on the land aircraft carrier, and the captain naturally had to report to his superiors.


    How can the high-level people not pay attention to such an adverse thing as 3D printing equipment after getting the news?


    "The 3D printing equipment is not as powerful as you think. It is mainly used for emergency preparation in the European battlefield." facing the representatives sent by the senior management and the military to ask about it, Chen Xin didn''t bother to explain. He took them to a 3D printing equipment he redone and showed them.


    "Now I use this machine to print a set of power armor. In addition, I have a set of power armor I asked someone to take from the factory. You can compare the difference between the two." Chen Xin said, and started the equipment to make it work and print the power armor.


    Because the internal space of this equipment is very large, a large number of parts can be printed together during printing, so the printing speed is very fast.


    But the representative from the top saw some clues, but he didn''t mention it here. He just silently watched the whole power armor printed in the form of parts.


    The parts were printed out and the workers called by Chen Xin quickly began to assemble.


    Originally, in terms of the design of the whole set of equipment, it was automatically assembled by the supporting mechanical arm and production line, but now it is just a display, so Chen Xin asked the workers to assemble it.


    A power armor has complex structure and many parts. It is not easy to assemble it. If there is only one person, it will take a lot of time.


    However, Chen Xin obviously couldn''t let the military and senior people wait so long, so Chen Xin called a group of skilled workers, who also brought various auxiliary tools, so it took only about two or three hours to assemble the whole set of power armor.


    As like as two peas of 3D printed power armor were completed, another set of power armour was prepared to be pushed forward. The two seemingly identical power armoured units were placed before the military and high-level representatives.


    "How long does it take you to assemble a set of power armor?" having roughly understood what Chen Xin wanted to express, he took the initiative to ask the workers aside.


    Without much thought, the workers quickly replied, "if we are on the production line, without considering the supply of parts, we can assemble 20 sets of power armor in 14 hours a day."


    In fact, this figure is a bit exaggerated. Under normal circumstances, the factory production line can not be transported to this production efficiency at full load.


    After all, there are quite a lot of parts required for power armor, which need to be produced in different factories and finally transported to the assembly factory for assembly.


    However, even if the country now concentrates a lot of resources, the operation efficiency of the factory production line is only a little more than 80%, because there is a lack of enough parts to make the production line run.


    This is mainly because of the shortage of resources. Now that the country is in a state of war, it is reasonable to concentrate all resources on the production of such war materials.


    However, with the change of the current situation, there are many places that need to invest resources. In addition to the production of war materials, there are many places that need resources.


    In addition, due to the unbalanced distribution of resources in China, a large number of resources need to be transported before they can be gathered in production plants. In order to avoid the waste of a large number of resources due to transportation, the country can only adopt the principle of nearby distribution as far as possible, which also leads to a large number of factories not getting enough materials to meet the needs of full capacity production.


    The high-level representatives naturally understood this, so when the workers said that they could assemble 20 sets of power armor a day, they naturally converted it into the actual output.


    But even judging by the actual production speed, the speed of 3D printing is still a little slow.


    Of course, this is not the key to the problem.


    "Academician Chen, how long will it take for a complete set of 3D printing equipment to produce a set of power armor?" the high-level representative asked Chen Xin this question.


    When he asked this question, the military representative went to the front of the two sets of power armor, reached out and knocked the two sets of power armor to check their quality.


    "In fact, it''s so fast. The advantage of 3D printing equipment lies not in its production efficiency, but in that it can produce anything when there are enough raw materials." Chen Xin explained to the representatives of senior management and the representatives of the military "The 3D printing technology I use is slightly different from the existing printing technology. It does not use laser welding powder printing, so it can print with a variety of materials, but it also brings a problem that more materials are needed for printing, not just one.


    Production efficiency is a big problem. It is destined not to replace the existing production lines. Therefore, 3D printing technology can be used on land aircraft carriers. They need to persist in the European battlefield for a long time and provide assistance to European countries. It is very useful to bring such a set of equipment.


    However, this technology is not suitable for domestic production. It is like having a machine that can make everything, but taking it to make only one thing. It is a waste.


    Research departments are still suitable for the use of 3D printing technology. Sometimes they need to produce some non-standard things or temporarily processed things. At this time, they only need to input drawings and dimensions into the 3D printing equipment to get what they want. It is undoubtedly much better than going to someone to produce, process and customize. "


    In fact, this is also the advantage and disadvantage of 3D printing. It is good to be able to print everything, but it also limits the application of 3D printing in production.


    After all, the processes and processes needed to produce a product are fixed. What is needed is to maximize production efficiency and produce what is needed quickly and in large quantities.


    At this time, instead of using a machine that can make everything, it is better to build a production line dedicated to producing this product.


    In fact, this is the same concept as the difference between using industrial machines to directly produce products and using industrial machines as a production line to produce products.


    It is not impossible to do so, but it is obvious that the latter can give more play to production efficiency and the advantages of 3D printing technology.


    After Chen Xin''s explanation, the senior representatives obviously understood Chen Xin''s meaning, but after a more detailed understanding of the various details of the 3D printing technology put forward by Chen Xin, they left with satisfaction.


    On the contrary, the military side, looking at a set of 3D printing equipment, suddenly had an idea of coquettish operation.

 Chapter 720

    "Academician Chen, can you design a small mobile base that can accommodate soldiers of a company, carry power armor, Titan, armored vehicles, tanks, helicopters and other vehicles, and have sufficient self-supporting capacity to stay behind the enemy for a long time?" the military representative asked Chen Xin, which was an idea he had temporarily planned.


    If we can use a vehicle such as a small mobile base to carry a special force of about a company, carry other vehicles such as power armor, Titans, tanks, armored vehicles and helicopters, and have the ability to stay behind the enemy for a long time, it will undoubtedly be very tempting in the war.


    After all, if such a force is pushed behind the enemy, as long as it is not found, it can bring quite a heavy blow to the enemy.


    Compared with the traditional use of special forces to destroy behind the enemy, special forces supported by heavy weapons and vehicles will be able to play a greater role.


    However, after thinking about it, Chen Xin shook his head and said, "of course you can do it, but it doesn''t make much sense! Even if such a small mobile base is as small as a big drive, it can hardly be hidden if it goes deep behind the enemy?


    Of course, in terms of the current environment, it has certain practical value. After all, now that we have lost the means of satellite reconnaissance, it is not a big problem to hide behind the enemy, but the enemy we are facing now is alien creatures? Do we need these to fight with them? "


    "No, no, academician Chen, you misunderstood." when the military representative heard what Chen Xin said, he quickly shook his head and explained to him: "this small mobile base is really considered to be used by soldiers behind the enemy, but at present, the military needs it more for small-scale troop mobilization."


    Hearing this from the military representative, Chen Xin was confused, which made him look at the other party and wait for the other party''s explanation.


    "The current environment is terrible. I believe you can understand that the cold weather and harsh environment are the enemies we need to face now without me saying more, academician Chen." Chen Xin thought the military representative or explained the purpose of this small mobile base in the future, but the other party talked about the environment: "Thousands of miles of sea is frozen, the whole territory is frozen, the original border posts are submerged in ice and snow, and the naval ships are frozen by the tsunami before the disaster. Under this situation, our military can no longer patrol and protect the border line.


    Although no one can cross the border line for at least hundreds of kilometers to see the densely populated snow field under this environment, the national border can not be ignored. Even if there is no such demand, we still need to maintain border patrol.


    Especially at sea, in Europe, alien creatures invaded from the Mediterranean, which may be related to the location where the meteorite fell, but no one can rule out that the invasion of these alien creatures is related to water. Therefore, the military is now trying to restart maritime patrol and border patrol.


    But academician Chen, you know, the environment is too bad. Even with power armor and exoskeleton protective clothing, it is difficult for our soldiers to patrol in the field in today''s environment.


    If the whole blue star had been shrouded in the dark before, it might not be a big problem, but now with the change of China''s environment, especially our renewed sunshine, it is certain that the surrounding countries will covet China''s territory.


    Even if the environment has not changed much, living in the sun and living in the night are completely different living conditions. These neighboring countries will never miss the opportunity to live in the sun, so we must strengthen our defense against the border! "


    The officer''s words made Chen Xin understand his ideas.


    He clearly nodded his head, took over the words of the officer and continued: "but now the environment is bad, not to mention that we still need to fight against alien creatures, which involves most of the strength and energy of the country and your military, so that the military can not send more people to maintain border patrol and border lines, not to mention nothing for maritime defense.


    At this time, I took out the mobile base and land aircraft carrier. I''m afraid you were planning to use the mobile base to rebuild the border defense. However, at that time, the military still had spare power to deal with it. The demand for the mobile base was not particularly large, so you plan to take your time.


    But now, on the one hand, we have to go to war with alien creatures. On the other hand, China has restored its sunshine, and its attraction to foreign forces has become much stronger. Under such circumstances, the military''s demand for border defense has also become strong.


    So you want to have a mobile outpost that can be stationed at a certain point and radiate a wide range of surrounding areas. You also have a certain combat capability, can find the enemy''s invasion, and can resist the enemy''s attack for a period of time or delay the enemy''s attack after encountering the enemy''s attack, so as to buy time for the mobilization of large forces. Am I right? "


    "That''s almost what that means. Originally, we just wanted a mobile base, but now academician Chen has come up with 3D printing technology, which is very useful!" the military representative looked at the 3D printing equipment aside, looked very excited and said to Chen Xin: "With this, our soldiers can get enough logistics support even if they are stationed in a deserted place. As long as they input enough drawings, they can build a camp by themselves!


    In this way, as long as they establish three or five strongholds around themselves and then travel around with mobile bases, it is enough to ensure the actual control of a large area, which is very useful for the current country! "


    This conversation with military representatives made Chen Xin understand their needs.


    This is not difficult for Chen xinlai, and the requirements put forward by military representatives are also urgently needed by the country.


    Therefore, Chen Xin didn''t refuse this, but said to the military representative, "you need a smaller mobile base, which is no problem. However, I need you to give more detailed requirements, such as how many people you need to carry, how many people you need to support, how long you need self-supporting ability at the same time, and what equipment you need to equip


    These problems need to be confirmed by you. After you confirm these requirements, give them to me, and I will design things according to your requirements.


    It''s not troublesome. Mobile bases are easier to do with small ones than large ones. Now we''d better solve the land aircraft carrier and supporting the European battlefield first. "


    When the military representative heard Chen Xin say so, he had no objection, nodded and left.

 Chapter 721

    The preparation of the land aircraft carrier was carried out quickly, and the personnel allocated by the military soon mastered the driving method of the huge land aircraft carrier.


    However, mastering driving methods does not mean forming combat effectiveness.


    Now they can only drive this huge land aircraft carrier, and there is still a long way to go before they can drive it to fight and give full play to its full performance and combat effectiveness.


    But the plan to support the European battlefield forced them not to have more time to adapt and master the land aircraft carrier.


    In particular, after they initially mastered the operation of land aircraft carriers, Chen Xin upgraded again and installed the original anti gravity device.


    This suddenly made the crew who had initially mastered the driving method of land aircraft carrier feel very uncomfortable. After all, it was not easy for you to work overtime and spend time mastering a technology. As a result, the technology was upgraded the next day. You need to start over again. Everyone will feel very uncomfortable.


    But these soldiers did not complain, but more seriously and invested in re mastering the relevant operation technology of the upgraded land aircraft carrier.


    On the one hand, it comes from their sense of mission and honor as soldiers, on the other hand, it is also the credit of the captain of this land aircraft carrier.


    As the captain, he has learned about his arrangement from Chen Xin and expected the installation of anti gravity equipment, so he has made preparations before.


    Therefore, these crew members can timely adjust their state and quickly re-enter their work.


    However, as a former naval officer, although he was satisfied with the land aircraft carrier in all aspects, he was still dissatisfied in some aspects.


    To this end, he specifically found Chen Xin and put forward his dissatisfaction.


    "Academician Chen, the land-based aircraft carrier is a good ship. Yes, the force is also very powerful, but is it too thin to have only one ship? What about the accompanying fleet?" this is the captain''s most dissatisfied with the land-based aircraft carrier and the most incomprehensible place.


    As an officer of the Navy, in the captain''s impression, the navy boat did not say, and the big ship was never a ship when it set out.


    Especially the aircraft carrier, as the core of the fleet, takes the whole aircraft carrier formation as an escort every time.


    Although some people boast that the aircraft carrier itself has strong anti Strike ability and survivability, and talk about the aircraft carrier that ate several nuclear explosions and did not sink, in fact, those who really know the aircraft carrier know that the aircraft carrier itself is fragile.


    Its strength depends on carrier aircraft and its escort formation.


    A simple aircraft carrier can sink with only one submarine, and even a torpedo boat can send a huge aircraft carrier to the bottom of the sea.


    Therefore, when countries use aircraft carriers, they will be equipped with a huge escort fleet.


    But the land aircraft carrier obviously did not, not only did it not have a convoy, not even a convoy.


    Of course, this is mainly because the land aircraft carrier is not a real aircraft carrier. There is no precedent to find and no experience to refer to if you want to establish an escort fleet.


    After all, there are two completely different concepts of operating an aircraft carrier on land and operating an aircraft carrier in the sea.


    However, when the captain asked Chen Xin this question, he naturally paid attention to it.


    But this is obviously not something that can be achieved overnight. Even if Chen Xin has systematic help, it is by no means easy to build an escort fleet that can match land aircraft carriers.


    Therefore, in the face of the captain''s request, Chen Xin can only temporarily promise to consider this matter, but can''t give him a promise.


    "I can''t help you with the escort fleet for the time being. Even if I can complete the design of the escort ship, it''s impossible to build such a fleet in a short time in the current form of the country." Chen Xin explained to the captain that this is also the truth. After all, even if there is a system, he can''t make things out of nothing.


    However, Chen Xin comforted the captain: "you don''t have to worry too much about this. Your ship has 3D printing equipment. After you enter Europe, you can ask European countries for materials and occupy a mining area under the banner of producing equipment for them.


    Then you can use 3D printing equipment to make more mobile bases and tanks, and use mobile bases and tanks to build a land defense system. Although it is not as good as your navy''s previous fleet, it can still work. "


    Chen Xin''s words are not just comfort. After all, 3D printing devices can do this.


    No fleet? It''s not a problem. As long as you dig all the way, the ore will be refined into raw materials, and then printed with 3D printing equipment. As long as the ore pipe is enough, it''s no problem how many fleets it takes for 3D printing equipment.


    Therefore, after hearing this statement given by Chen Xin, the captain can only leave reluctantly. After all, the current situation is so, and it is really impossible for the state to build a whole fleet for him.


    But after the captain left, Chen Xin did not give up thinking about it.


    As the captain said, the aircraft carrier really needs the cooperation of the fleet to play its maximum role.


    And even if we can''t build a frigate fleet for the time being, it won''t take much resources to think about how to design a land frigate.


    Compared with the aircraft carrier at sea, the land aircraft carrier is not much different in essence, but Chen Xin emphasized its strike power when designing the land aircraft carrier, which can launch more missiles, and can not build the flight deck as large as the sea aircraft carrier.


    This leads to a small gap between land and sea in the design and consideration of frigates.


    Artillery giant ships are no longer popular in modern war. In those years, federal warships wanted to use plastic. The destroyers known as the world''s most advanced destroyers used carbon fiber as materials.


    However, the cost of shipbuilding is so high that the world''s first economy like the Federation can''t afford it. Moreover, for land, a certain amount of defense is still necessary. At least it can''t be hit by civilian ships, and the whole ship''s side is torn like paper.


    After all, there are more problems and attacks on land than at sea.


    At sea, you can''t let a team of frogmen dive to bomb warships at the bottom of ships, but on land, it''s not easy for a team of special forces to bury mines and explosives on the moving base or the forward route of land aircraft carriers.


    Therefore, defense must be the key points, and there must be a certain obstacle removal ability, which can open up a way forward for land aircraft carriers, and also have the strike ability of fire platform.


    In short, the frigate required by the land aircraft carrier must at least have the defense and firepower to resist the attack of infantry, and can also cooperate with the land aircraft carrier for accompanying action


    To achieve these goals, there are too many things to consider in the design of such a land frigate, and Chen Xin has to turn to others.

 Chapter 722

    Regarding the design of the land-based aircraft carrier frigate, Chen Xin brought in weapons experts from both the army and the Navy.


    Of course, land aircraft carriers belong to land vehicles. Army weapon experts undoubtedly have the most say in how to design the defense of frigates and use those weapons to fight.


    However, this large weapon platform has never existed in the army. Even if there is a mobile base as a reference, it still needs naval weapon experts to provide some valuable experience.


    After all, compared with the army, the navy is an old expert in playing with such big guys.


    "I suggest not to design such a land frigate too large." the first person to express his opinion was a naval weapons expert, who told Chen Xin: "as a frigate, its main significance is to protect land aircraft carriers, so everything should be carried out around this purpose.


    The Navy used to make ships so large, which was based on actual needs. Ocean navigation has requirements for the size of the hull, but it can''t be made small.


    After all, the wind and waves on the sea are so big that the hull is small and the ability to resist wind and waves is small. When a wave comes, the whole ship is thrown up. What else to talk about.


    But you use it on land. It''s OK to carry enough defensive weapons. You don''t need to consider ocean navigation and self-reliance. You don''t need to be so big. "


    Listening to the words of the naval weapon expert, Chen Xin still nodded slightly. When he felt that what others said was reasonable, the army weapon expert on one side was not happy: "what does it mean that our army doesn''t need to build so big? Together, your navy can build big guys, right?"


    Of course, army weapons experts are only joking, not really having any opinions.


    However, for the army, it is also their dream to have the opportunity to build big guys.


    After all, the navy can''t move thousands of tons or tens of thousands of tons of ships, just like dumplings. The army doesn''t even have hundreds of tons of things. Sometimes it will be used as a stem to make fun of, and sometimes the army itself will make fun of it.


    Of course, jokes are jokes. During the serious discussion, the army weapon experts still said very seriously: "I suggest to adopt a more mature design, first design a general chassis, and then install different weapons and equipment on the chassis according to different functions.


    This design can adjust the formation of frigates according to different mission requirements to meet the needs of air defense, land and other operations, and the common chassis parts can also facilitate logistics maintenance and maintenance, which can be greatly improved for the continuous operation of the whole fleet outside. "


    It is really a good design idea to adopt a unified general chassis and then replace different modules to achieve different functions.


    A unified chassis means that parts are universal, which can save a lot of energy and consumption in production and logistics maintenance.


    The benefits of the universal chassis include the replaceability between different functional modules. When necessary, the damaged module or chassis can be removed and replaced with usable spare parts, so that the combat effectiveness can still be maintained.


    If different chassis designs are adopted, there will be no such convenient functions, and one more model of parts is also an additional burden for logistics and production.


    We not only need to prepare twice as many parts, but also have to design another production line, which will cause more consumption.


    So on this point, both army and Navy weapons experts agreed, but the two sides had a dispute over how big the chassis was.


    "I still don''t think we can make it too big. It''s too big and inflexible. It''s inconvenient for production, maintenance and use." the Navy''s weapons experts still insist that we can''t make the frigate too big.


    However, the army''s weapon experts argued with reason. Obviously, they didn''t want the frigate to be too small: "what''s the use of making it too small? If it''s too small, I might as well directly use 4-25 anti-aircraft guns and tank clusters to match the helicopter!


    The frigate of the land aircraft carrier needs to act together with the land aircraft carrier. It shoulders a variety of combat tasks such as escort, obstacle removal, air defense and investigation. How can it be competent for these tasks if it is too small? "


    "Even so, with such a large tonnage, not to mention how to build it, such a heavy weight is enough to move? Moreover, land is not better than the sea. Except for plain terrain, where can you find a place where you can pass such a large tonnage guy? Moreover, it is still a fleet trip, which is not practical on land!" after a quarrel, the Navy''s weapons experts, I''m about to pat the table angrily.


    However, the army''s weapons expert did not know this, but he still wanted to get a big enough guy for the army.


    Listening to the quarrel between the two sides, Chen Xin had to come out and make things right. He said to the two weapons experts, "both of you have extinguished the fire. In fact, I have solved the problem of passage. Land traffic capacity is not a factor limiting the tonnage of land frigates."


    "What? Solved?" the army and Navy Weapon experts looked at Chen Xin together. They didn''t know that the land aircraft carrier had anti gravity devices and could fly in the air.


    This matter is also confidential within the military and senior management. At present, it has not been made public. Therefore, even army and Navy weapons experts do not know about it.


    However, it''s not that we can''t tell the two weapons experts. After all, if we ask them to help design the frigate, the information we should know should still be said.


    So Chen Xin explained to the two weapons experts and let them know about the anti gravity device.


    After listening to Chen Xin''s explanation, the two weapon experts were stunned. It took them a long time to recover and digest the information he said.


    "If so... Can''t an aircraft carrier fly?" the Navy''s weapons expert thought of the aircraft carrier on the way.


    "It can fly, but it still needs to be used with the propulsion system. The anti gravity device itself can only realize the floating air energy." Chen Xin nodded affirmatively.


    When Chen Xin said that he could fly, the eyes of the two weapon experts met and flashed brilliance from their eyes.


    The army weapon expert said: "in this case, we should design on the premise that the frigate is in flight. Flying in the sky has more to consider than walking on the ground."


    "Yes, if you fly in the sky, the weapon range is completely different, and the overall structure of the platform and the arrangement of weapon positions also need to be reconsidered." the Navy''s weapon expert nodded in agreement.


    Seeing that the two sides reached a consensus, Chen Xin was a little relieved and discussed with two weapons experts how to design the frigate allocated to land aircraft carriers.

 Chapter 723

    When Chen Xin led weapons experts to study how to build frigates that can accompany land-based aircraft carrier operations, it seems that alien creatures have finally recovered from the impact of the storm and launched a new attack on the defense line in the Dongting Lake area.


    Of course, this is expected by the high-level and the military. In fact, it took alien creatures so long to resume the attack, which surprised the military.


    After all, although the previous storms caused great damage to alien creatures, in fact, the lost alien creatures only broke through the ground.


    Although the number is huge, in the military''s view, there is not much difference between this and the number of operational daughters lost by alien creatures in the process of attack.


    So it took alien creatures so long to resume the attack, which really surprised the military and worried about whether alien creatures were brewing any conspiracy or other attack plans.


    However, under the surveillance of the satellite, no abnormality was found.


    In the face of such a situation, the military can only strengthen the defense of the defense line, make everyone vigilant and beware of the possible conspiracy of alien creatures.


    However, alien creatures seem to have only recovered to the attack before the storm, showing no special place.


    Moreover, the humans they face have further strengthened all the defense lines during the armistice caused by the previous storm, not only improving the defense against the impact of alien creatures, but also installing more defense machine guns and heavy artillery.


    Human beings with satellite surveillance have opened a full map perspective at this time. Every move of alien creatures can be seen clearly.


    Originally, due to the lack of light, the firing of artillery only depends on the calibrated firing area in advance, and then blind firing. The shelling effect and whether it hits or not all depend on the feedback of front observation posts and air calibration.


    But the two are also affected by the lack of light, which makes the effect of shelling not good.


    With the restoration of light and the re launch of satellites, mankind can finally restore the original accurate artillery and missile attacks.


    Use powerful missiles to directly attack the passageways and exits of alien creatures, cut off their military lines, and then use carpet artillery to annihilate the advancing military peaks. There is no need to send air force for bombing. Only with the cooperation of the army and rocket army, an alien attack was annihilated.


    A large number of machine guns in the forward position did not even get much chance to shoot, because after the military line in the rear was cut off, alien creatures could no longer fill the vacancy cleared by artillery bombardment with a flood of water, resulting in not many combat sons who could rush to the front of the defense line.


    So all of a sudden, the pressure on the defense line seemed to be reduced a lot out of thin air, without the pressure that seemed to be broken in the next moment.


    Such a situation immediately made the military feel relaxed and vigilant. No one can guarantee whether this is the plan set by alien creatures.


    Although it is not surprising to have such a result from the immediate situation, it is incredible for everyone that the victory came so easily.


    However, while being vigilant, the military is also rapidly implementing the plan to reinforce the European battlefield.


    Having adapted to the driving mode of the land aircraft carrier and preliminarily mastered the operation mode of the anti gravity device, the land aircraft carrier and its mechanized reinforced infantry regiment equipped with power armor will set off north to Lucia and join the reinforcements there to gather a brigade to reinforce the European battlefield.


    However, although the reinforced infantry regiment was fully staffed and all the soldiers had received training in the operation of power armor, they were not equipped with power armor, and even the exoskeletons of their original equipment were removed.


    This is not that the military is stingy and even reluctant to provide them with complete equipment, but that the military intends to let the army make up all the equipment on the road by itself in the way of manufacturing equipment all the way as envisaged by Chen Xin.


    This is also a test of the 3D printing facility carried on the land aircraft carrier to test whether it can meet the needs of actual use.


    As for the required raw materials, they are provided by the mining areas on the way during the progress of the land aircraft carrier.


    Some of these mines are still in operation, which can directly provide ore and raw materials, but for some mining areas that have stopped operation, they can only be mined by land aircraft carriers.


    For this test, neither the military nor Chen Xin is very sure. Although after calculation, the super large 3D printer specially designed by Chen Xin loaded on the land aircraft carrier can meet the needs of producing so many power armor, it is still worrying whether they can obtain enough minerals.


    Out of preparation for this issue, in fact, China has prepared a batch of equipment sufficient to arm the regiment. After they arrive in Europe, get in touch with European countries and establish strongholds, they will be transported from the domestic side.


    For all the members of the land aircraft carrier, this will be a voyage they have never had, and it will also be a great test for them.


    Before their departure, Chen Xin also provided them with another gift as a gift before their departure, that is, the design drawing of the land frigate just completed by him and the weapon experts and designers of the army and navy.


    This type of frigate, like the land aircraft carrier, is equipped with anti gravity devices, but this part is removed from the drawings given by Chen Xin because of the confidentiality of the anti gravity devices.


    In other words, land aircraft carriers can indeed manufacture land frigates with anti gravity function, but they can not manufacture anti gravity devices. Therefore, after the frigates are built, they can only be used for ground use and can not fly in the air.


    However, this has little impact, because the anti gravity device can be transported and installed after it is completed in China, which will not cause any impact.


    As for the escort on the way to Europe, after the land aircraft carrier is equipped with carrier aircraft, tanks, anti-aircraft guns and other vehicles, it actually has sufficient self-defense capability.


    Although there may be some problems facing the attack of alien creatures, if some people with ulterior motives want to make things, there is still no problem at all.


    And Chen Xin didn''t really let a land aircraft carrier go to Europe.


    Although it is really too late to build a new frigate, it can only be said that preparing the design drawings for the land aircraft carrier is better than nothing. After all, they will not be able to obtain enough materials and have enough time to manufacture frigates until they arrive in Europe, but this does not mean that there is no other way.

 Chapter 724

    The cold wind was blowing, and the snowflakes were like a mass of white filling the gap between the sky and the earth.


    The lead gray sky is low and dark. The dark clouds that cannot be penetrated by the sun have a faint yellow. Only a glimmer of light from the distant horizon can make this dark ice field not dark.


    This is the Shandong Peninsula of Yanguo, but it should be called Shandong island now.


    With the rise of coastline, the whole Shandong Peninsula has been separated from the mainland and turned into a complete island.


    However, although it has become an island, the people''s life in this area has not been greatly affected.


    At the beginning of the disaster, the people in this area were temporarily moved inland. After the surface environment stabilized, they returned to this area and settled here.


    As for the country, although it is very difficult, it has been trying to maintain the material supply in this area and ensure the production and life of the people in this area.


    Originally, there was no difference between here and other places after the Yanguo disaster, and there was nothing that could attract the attention of high-level officials.


    But when Chen Xin arrived here by plane, there was a rare bustle here.


    A large number of staff are constantly busy, chiseling the thick ice with various tools, which looks like a hot scene.


    "Academician Chen, this is the naval port before the disaster, and all the warships of the Northern Fleet were parked here before the disaster." a naval officer said to Chen Xin in a complex tone, but his eyes looked at the huge steel ship frozen in the ice and snow ahead.


    When the disaster came, the world set off a large-scale tsunami, the rise of sea level even destroyed all coastal cities.


    In the face of such a tsunami and disaster, even the largest warship built by mankind - aircraft carrier is just a small sampan manipulated by nature.


    Therefore, in order to avoid the destruction of these warships, which cost a lot of national resources and efforts, the Navy tried every means to park them together and put them in the military port in order to avoid all of them being destroyed by the tsunami.


    The Navy''s efforts were not in vain, but they did not play a great role.


    These warships were not destroyed by the tsunami. Except that some warships were crushed and damaged, most of the warships parked in the military port were just flooded, and they could be reused as long as they were overhauled.


    However, they have become "useless".


    Because the whole world is frozen.


    The whole ocean, all rivers, lakes, everything, all water bodies are frozen by the extremely cold low temperature, and these warships that leave the ocean are just a pile of scrap iron are frozen in the frozen ocean.


    All warships have been frozen, like huge monuments. They represent the glory of mankind and the strength and prosperity of yesterday.


    Now, however, they are just a pile of scrap iron frozen in the ice.


    Originally, the state has given up recycling these warships, only to see if there is a chance to disassemble them and recycle the steel and other resources on them.


    A small number of badly damaged warships have actually been disassembled, but with the decreasing temperature, the work has become more and more difficult and stopped.


    Therefore, most of the warships in the military port are still intact, but they have lost the opportunity to sail on the sea again.


    Now, Chen Xin has put forward a new idea, which seems to give these warships a chance to live again.


    "Academician Chen, all the warships of the Northern Fleet, including the flagship aircraft carrier, are here. What are you going to do with them? Can these warships really be used again?" the naval officer asked Chen Xin with some expectation in his eyes.


    As a naval officer, of course, I don''t want to see the large fleet built by generations after a lifetime of struggle be abandoned.


    But the reality has made these warships useless. In addition to being disassembled and recycled, he really can''t think of any place where these warships can be used.


    However, as a scientist who has been working miracles all the time, Chen Xin suddenly proposed that these warships could be used for other purposes, which undoubtedly gave the Navy another glimmer of hope.


    Considering that the army can have land aircraft carriers, it seems not impossible for the navy to reopen these warships?


    When the officer thought so, Chen Xin said to him, "I intend to transform these warships into land-based warships so that they can move again and contribute to the country''s national defense again."


    "Land ship? Is it a large vehicle like the land aircraft carrier and mobile base?" the eyes of the naval officer lit up when Chen Xin said so.


    As a naval officer, he certainly could not have known about the land aircraft carrier. After all, the crew were all from their navy, and the navy was very concerned about this matter.


    After all, large vehicles have always been the patent of the Navy, and the army has never had such a big house.


    Therefore, although it is called a land aircraft carrier, the crew driving the land aircraft carrier still needs to be provided by the Navy.


    This also gives the Navy more hope that with the increase of large vehicles such as mobile bases and land aircraft carriers, the Navy, which now seems to have lost its function, will rejuvenate itself in another form.


    However, what the Navy didn''t expect is that Chen Xin not only revitalized the Navy, but also put these warships that had to be disassembled into new use.


    Following Chen Xin, naval officers came to a warship with him.


    This is an old warship. Although it is also an active warship of the Navy before the disaster, compared with the new warships in service one after another, this is an old warship that has fallen behind.


    As an old warship that has been in service for more than ten years, it is also approaching the retirement age. However, due to a catastrophe, these old warships did not wait for a glorious retirement ceremony, but were frozen in this military port together with other warships.


    Now, these veterans who have served for more than ten years seem to be dressed up again and back on the battlefield.


    On the hull of the old ship, a group of workers are cleaning the frozen ice on the hull, while another group of workers are chiseling the ice at the bottom of the hull to separate the ship from the ice.


    Looking at the busy workers, Chen Xin once again projected the design drawings of the land ship with nano molecules through his watch, compared it with the warship in front of him, and prepared to upgrade the warship, so that the old warship could radiate vitality and brilliance again.

 Chapter 725

    In the narrow and closed bridge, operators are sitting in front of the equipment, staring at their screens.


    The officers sitting in the captain''s position are slightly uncomfortable. Although they have been on the ship for several days, as army officers, they are still not used to this naval bridge.


    "Pilot, report our current position." it seems that in order to alleviate the discomfort caused by this small habit, the captain asked the pilot who was operating the radar.


    Because the bridge is small, there are not many people on the bridge. In addition to the captain himself, there are only four people: the helmsman, the communication officer, the first mate and the navigator asked by the captain.


    "We are now at XX degrees east longitude and XX degrees north latitude. The radar shows that everything is normal." the pilot glanced at the radar and reported to the captain.


    Listening to the pilot''s answer, the captain clearly nodded his head and asked, "how far are we from our destination?"


    "According to the radar, we are still about 80 kilometers away from the destination. At our current forward speed, we will arrive in six hours." the pilot just measured the distance on the radar and gave an accurate reply to the captain.


    The captain could not help but breathe a sigh of relief. He was still a little nervous about carrying out such a task for the first time, but now he was relieved to hear that he would arrive at his destination in six hours.


    The vehicle he was driving, or warship, was the land ship newly equipped to the army.


    However, this is not a newly built warship, but Chen Xin transformed it with those warships frozen in the military port.


    Its prototype is an old navy warship. After Chen Xin''s upgrading, it has now become a land ship.


    The ship body and the original ship body of the navy have been greatly changed. There are four more tracks under the original ship body as the traveling mechanism, and the bow part has been transformed into a huge dock to accommodate the tanks, armored vehicles and other vehicles carried on the ship.


    As for the part of the deck, because the bow did not need to break the waves, it was also changed from the original pointed head to flat head, and the armament was strengthened at the same time.


    The original naval gun on the front deck has been upgraded and a double mounted 75mm electromagnetic gun has been installed, while the original missile launch port on the deck has been moved to the rear deck. At the same time, the bridge has been moved forward after shrinking, making the deck more compact and compact.


    In addition to the missile launch port, the original helicopter hangar and take-off and landing platform are retained on the rear deck.


    In addition, two single mounted 75mm electromagnetic guns were added on the side, and the original smoke exhaust pipe was removed.


    After all, after the replacement of the new nuclear power system, there is no need for the original huge oil tank and engine room, nor for the huge chimney.


    As a result of this transformation, the original 100 meter long ship body has been shortened to only more than 70 meters, and the hull has become low and compact.


    However, because the original ship type of the ship was a destroyer, after it was transformed into a land ship, Chen Xin did not change its purpose, but took it as an implementation plan for a small mobile base used to maintain the border discussed with the military before.


    The original helicopter hangar on board is still reserved, but Chen Xin also installed the 3D printing equipment here.


    Usually, this is the hangar for parking the helicopter, but when necessary, you can move the helicopter to the take-off and landing platform at the stern, and then turn this into a 3D printing workshop for printing what you need.


    The reason why the two are combined is also to save space. After all, the whole ship is so large. In order to travel better on land, Chen Xin has also reduced the volume and length. Under the limited space, it is really impossible to set aside space for 3D printing.


    At the same time, after Chen Xin''s upgrading, the number of pilots required by the land ship has also decreased greatly, and the number of necessary passengers has even been pressed down to less than 50 by Chen Xin.


    However, according to previous military requirements, in addition to the crew, the land ship is also equipped with an enhanced aircraft company for border patrol and other combat tasks.


    According to the original plan, they will arrive at the border area of Inner Mongolia, establish three permanent strongholds in the border area and resume border patrol, and this land ship is the support for them to implement this plan.


    For the tasks assigned by the military, the captain did not have any ideas other than completing the tasks.


    As a soldier, obeying orders is a bounden duty, not to mention the task of defending the country.


    But the captain was still worried about how to better complete the task.


    After all, whether it''s equipment or mission, or the environment in which the mission is performed, it''s the first time for the captain. He really doesn''t know how to establish a permanent stronghold in such an icy and snowy environment.


    Although before departure, the military equipped the land ship with a scientific officer specially responsible for this matter and an engineering team assigned to the ship, the captain also had detailed communication with each other these days and learned that the 3D printing equipment provided to them was the key to completing this task.


    But for the captain, in the face of areas he had never touched, he still had no bottom in his heart.


    Just as a soldier, he retreated in the face of difficulties, which is really not a qualified soldier. Therefore, although he has no bottom in his heart, he still firmly believes that he will successfully complete the task.


    Just after the captain considered whether to rotate with the chief mate later, he went to the science officer to ask about the establishment of a permanent stronghold, but the communication officer on the side suddenly opened his mouth and reported: "report to the captain, ship 2 sent a communication, asking whether it is necessary to speed up the progress and arrive at the target site earlier."


    After hearing the inquiry of ship 2, the captain thought about it and said to the communication officer, "reply to ship 2 and maintain the current forward speed."


    The captain did not agree to the proposal of ship 2. Although they are advancing at cruising speed, they can indeed advance to full speed to reach the target site about an hour in advance, for the sake of safety, the captain decided to maintain the current speed.


    This land ship is not advancing alone. There are three other land ships around him, but only ship No. 2, which sent communication, is on the border garrison mission like this land ship.


    The other two land-based ships have different configurations from them and will continue to move forward to catch up with the land-based aircraft carrier that has gone to Lucia and go to Europe as the escort formation of the aircraft carrier.


    Therefore, considering the requirements of formation advance, the captain does not intend to accelerate and everything is safe.

 Chapter 726

    As this formation did not go straight from the land to the Dongting Lake area, it went upstream along the Yangtze River from the open sea.


    On the one hand, it gives the crew time to be familiar with the ship operation, on the other hand, it is also a long-distance navigation test for all ships of the whole fleet.


    On this formation, Chen Xin naturally also installed anti gravity devices. Both land aircraft carriers and other land ships in the formation are equipped with anti gravity devices.


    However, under normal navigation, although the anti gravity device remained open, it did not let the ship fly.


    It operates in a way that offsets the weight of the hull itself and reduces the burden on the load-bearing structure and traveling mechanism.


    "Academician Chen, since the anti gravity device installed on the ship can make the ship fly, why don''t you just make all the ships into spaceships?" in the tower of aircraft carrier Cambridge, a major general of the Navy suddenly asked Chen Xin looking at the fighters undergoing takeoff and landing training on the deck.


    This is something that many people don''t quite understand. Since there is anti gravity technology, why not just build a floating fleet? Instead of letting the fleet climb on the ground?


    For this question, Chen Xin can only reluctantly shrug his shoulders and answer major general: "General Zhang, it''s not that I don''t want to, but with the current anti gravity device technology, to build a floating fleet means a considerable amount of energy consumption. Even the micro fusion reactor just meets its energy consumption demand.


    On the other hand, I can make things, but then scientists will not be able to understand how I do it. "Chen Xin also paused and helplessly spread his hands: "In fact, even for the current anti gravity device, in terms of China''s scientific research force, it is not easy to understand its principle and copy a device with the same function. Even if I provide drawings, I''m afraid it will take at least ten years to produce results."


    Hearing what Chen Xin said, the major general called General Zhang could only understand and reluctantly nod.


    As an old navy, after decades of Navy construction, he certainly understands how difficult it is for such high-tech products to produce finished products.


    Even if you buy a complete set of technology from others, it will take several years to understand the R & D and design ideas and master the core technology.


    Moreover, even if we master the technology and want to put it into practical application and production, it still needs a long period of technical research and development.


    Therefore, Chen Xin said that if the effect is further improved, the researchers will not understand it. Now it will take ten years to copy the same thing. The old general still understands it very well.


    However, Chen Xin also saw the old general''s urgency, so he comforted him: "General Zhang, you don''t have to be too disappointed. Now the anti gravity devices installed on these land ships have a very good effect. Although usually considering the relationship between energy consumption and hull bearing capacity, they only operate at low power consumption by offsetting 80% of the hull weight, they can still start the full power operation mode to make the hull fly when necessary, but the duration can''t be too long ¡£¡±


    "I know. I''ve seen it before when we entered the Yangtze River from the Shanghai stock market. It''s amazing that such a big ship can fly!" General Zhang couldn''t hide his excitement.


    As an old navy, it''s exciting to watch the originally frozen fleet gallop again, not to mention watching these behemoths weighing tens of thousands of tons fly up and shuttle through the sky.


    The shock of such a scene can hardly be expressed in words. If general Zhang hadn''t been in good health, I''m afraid there would be something wrong with his excited heart just seeing such a scene?


    However, after the first excitement, the old general had some tolerance for such a scene, although he was still very excited every time he saw the fleet taking off to cross the River Bridge on the Yangtze River.


    Just as Chen Xin and general Zhang were discussing some problems of floating navigation of land ships, the ship suddenly sounded the alarm.


    However, General Chen Xin and general Zhang were not nervous about this. They just asked the staff of the tower: "is there another bridge ahead?"


    This has sounded more than once in the days after the fleet entered the Yangtze River, and everyone is used to it.


    "Yes, we have arrived at the three towns in Hubei Province, and there are many Yangtze River bridges ahead." the staff were not nervous about this, and calmly answered their questions.


    At this time, a broadcast also sounded on the ship: "the ship is about to start anti gravity navigation, and there will be bumps in the rising process. Please pay attention to grasp the nearby handles and fix yourself to avoid falling. The flight take-off and landing on the deck is suspended, and all staff please enter the deck bunker."

    The huge land aircraft carrier gradually rises from the ice under the action of anti gravity devices, and the shadow cast by the huge ship body is enough to cover an entire block.


    Such a huge thing flew from the sky, which brought unimaginable shock to people on the ground.


    Especially when the tens of thousands of tons of giant ships fly over from low altitude, there is a soul stirring sense of oppression because of the vibration caused by gravity.


    However, Chen Xin, who is standing on the outer corridor of the bridge and looking at the city under his feet, can only sigh.


    Different perspectives bring different feelings.


    Seeing such a huge ship of tens of thousands of tons passing from the top of the head on the ground is naturally shocking and oppressive, but if you stand on the side of the ship and watch the city passing under your feet, you will feel another mood.


    For Chen Xin, this is his third visit to Sanzhen after the disaster.


    Compared with the last two times, this time the city brought him a very different feeling.


    When Chen xinlai first came, the city was in the post disaster reconstruction period, but at that time, the sky had been covered by dust and the whole city was shrouded in darkness.


    At that time, there were a large number of reconstruction projects in the city, and even the streets were cleaned. Although the city was full of ruins, which could not hide the desolation and decline after the disaster, it also had a thriving vitality.


    However, when we look at the city again, although the whole city is covered with snow, we can still feel the vigorous vitality of the city.


    Most of the reconstruction projects under construction have been completed, but the city is still noisy. It is a new construction project.


    Most of the old ruins have been cleaned up, and the damaged buildings have been demolished. What is being built in the city is a huge dome.


    Looking at the dome close to the top, Chen Xin''s face was mixed with pride and exclamation.


    General Zhang noticed Chen Xin''s sight and expression and said with a smile: "that''s the urban dome project started by the three towns this year. It is said that it plans to cover the blocks with domes in the city, build a new urban area and restore the life before the urban disaster."


    Speaking of this, general Zhang seemed to remember something, and praised Chen Xin: "look at my memory, didn''t academician Chen put forward the scheme and design of the Dome City? You should have a sense of achievement that this technology can be applied to the actual urban construction?"


    "I don''t have a sense of achievement, but I feel that I have finally made some contributions to the country and the people." in the face of General Zhang''s praise, Chen Xin is quite modest. Although he has a trace of pride and pride in his heart, it''s still not suitable to show off in the open.


    However, for Chen Xinqian, general Zhang said with a smile: "young people''s modesty is a virtue, but excessive modesty is hypocrisy. Academician Chen, you have made many contributions to the country. Everyone can see how much you have made. Your achievements are completely worthy of pride and pride. Others will only praise you. No one thinks you are complacent."


    What general Zhang said is naturally a sincere truth. In his opinion, Chen Xin, who has contributed a lot of new equipment to the army, made outstanding contributions to the cause of national defense, and made many contributions to the post disaster reconstruction of the country and the construction of people''s livelihood, definitely deserves the praise of the country. He is proud of his achievements.


    Just listening to General Zhang''s praise, Chen Xin has no pride or pride.


    If he was really proud of watching the dome built in the city just now, which provided new shelter for the people in the city, Chen Xin had lost his complacency after general Zhang said so.


    On the contrary, he shook his head and sighed at General Zhang: "I just don''t think I''ve done enough, and now the country is not stable and peaceful, but it''s not time for me to feel proud of my contributions to the country!"


    Chen Xin''s words made general Zhang look sideways. At the same time, he nodded sympathetically: "it''s also said that the country can''t talk about stability and peace until the war of alien creatures is over. Our task is still very heavy!"


    With that, general Zhang looked in the direction of the bow and looked into the distance in that direction.


    That is the direction of Dongting Lake, and it is also the battlefield where Yanguo fights with alien creatures.


    If we can''t solve the problem of these alien creatures, for Yanguo, we must put a lot of resources and valuable manpower into this battlefield all the time.


    Although it is impossible to talk about the return of interests to protect the country, for the country, the war does not see any return, but is constantly consuming resources.


    This is obviously a great loss for the country. Only by ending the war one day earlier can these resources and manpower be invested in national construction one day earlier.


    Chen Xin and general Zhang obviously know this, so they just want to end the war as soon as possible.


    "Now with this fleet, I believe it should play a certain role in the war situation and end the war as soon as possible." Chen Xin is not sure about this. Although he says that land aircraft carriers are as powerful as aircraft carriers at sea, he always feels that land aircraft carriers can''t play much role in dealing with alien creatures.


    "With this fleet, we will have more advantages in dealing with the attack of alien creatures, and we will certainly end the war as soon as possible." General Zhang smiled at Chen Xin, and couldn''t help patting the railing of the portico next to him. Obviously, as an old navy, he has full confidence in the aircraft carrier.


    In this regard, Chen Xin can only smile and say nothing more.


    However, his eyes flashed over the fighter waiting to take off on the deck, and he suddenly thought of something, so he asked General Zhang: "when they train to take off and land, do they train when they travel on the ground?"


    "Yes, what''s the problem?" General Zhang was stunned when he heard Chen Xin suddenly ask this question, but he quickly answered his question.


    "This land-based aircraft carrier has the function of floating in the air. In the future, it should be necessary to take off and land in the floating environment? Can they try to take off and land in the floating state?" Chen Xin doesn''t know much about the Navy and carrier aircraft, but looking at the aircraft parked on the deck, he thinks it should also take off in the floating state.


    Hearing what Chen Xin said, general Zhang couldn''t help thinking about it. After thinking about it, he said, "it seems that I can practice. I''ll go back to the captain and talk about it."

 Chapter 728

    On the dark ice sheet, a huge steel creation floats in the air and is moving forward slowly driven by the engine at the tail.


    Around the giant ship, three smaller steel warships are floating around it, guarding the safety of the giant ship.


    Lights of different shades and colors are on the deck of the giant ship, and lines and indicator strips are outlined on the deck.


    A fighter was lifted up from the hangar, and the fighter ready for take-off was towed to the take-off position under the traction of several deck staff.


    At the same time, another group of staff connected the landing gear at the bottom of the aircraft to the ejection track of the electromagnetic catapult.


    With the rise of a baffle at the tail of the aircraft, the pilot finished the final inspection before takeoff, made a ready gesture to the ground crew on one side, and applied to the tower for takeoff at the same time.


    The tower quickly approved the take-off. In the take-off gesture made by the ground service, the engine at the tail of the fighter jet a bright flame, and then it was ejected in an instant.


    As the fighter was ejected, the other two fighters waiting on the side of the deck also started their engines and prepared to take off.


    However, unlike the fighter that was ejected, the two fighters took off by taking off and landing vertically.


    After the three fighters took off separately, the elevator at the corner of the deck lifted the fourth fighter onto the deck again, completed the preparation before takeoff in a very short time, and also took off from the deck by means of electromagnetic ejection.


    The four fighters that flew into the sky formed two double aircraft formations and began flight training over the whole fleet according to the scheduled plan.


    At this time, in the tower, several officers are counting the training results of this take-off.


    "The speed of ejection and take-off has basically been the same as that of peaceful take-off, which is a very good achievement!" an officer was very happy to see the time counted from the preparation of the fighter in the hangar to the final ejection and take-off on the deck.


    Another officer on the side shook his head and said, "but the vertical takeoff and landing speed is still too slow, even slower than the ejection take-off. Although it is necessary to wait for the runway clearance after the ejection take-off to avoid interference, the speed is still unsatisfactory!


    The timeout from the standard take-off time is 12 seconds, which completely wastes the advantages brought by the simultaneous vertical take-off and ejection take-off. It seems that we should strengthen the training in this regard! "


    "It''s not to blame the soldiers! After all, there was no model that could take off and land vertically in China before. Everyone was not familiar with vertical take-off and landing. Now it''s still in the exploratory stage, and it''s acceptable to slow down." previous officers were optimistic and persuaded dissatisfied officers.


    While the two officers were talking about this, the captain on the side said: "if you are not familiar with it, you should seize the time to get familiar with it. If you don''t understand it, you should seize the time to understand it. If you haven''t explored the effective take-off and landing process of travel, you should explore and practice more!


    Unfamiliar is not an excuse. There is not much time left for us. According to our current speed, we will reach the territory of Germany in another week. To contact European countries, we must form a combat deterrent as soon as possible. "


    Hearing what the captain said, several officers stopped arguing and discussed how to formulate a new training plan.


    The captain looked at the map in front of him with some anxiety and felt some anxiety about the upcoming contact with European countries.


    They are now on their way to Europe. In addition to their aircraft carrier and the three escort land ships that later arrived in Lucia to form a formation, there are also two transport land ships made with 3D printing equipment with the help of resources provided by Lucia when they stayed in Lucia.


    The two land-based transport ships are equipped with two infantry regiments established by Lucia and a Yanguo infantry regiment carried on the land aircraft carrier, which is just the strength of a brigade.


    They are all the reinforcements sent by Yanguo and Lucia to the European battlefield.


    However, this fleet to reinforce the European battlefield is still somewhat strange, because only Yanguo''s land aircraft carrier and three land frigates are equipped with anti gravity devices.


    This also led to the fact that when the Yanguo people carried out floating combat training, the lucians could only watch the Yanguo people fly in the sky, while they themselves could only follow on the ground.


    Of course, the lucians were very jealous and asked the people of Yanguo. After all, how fragrant is the floating warship? I will understand it after seeing the floating fleet.


    However, this kind of eye heat and true fragrance of lucians are used by Chinese people. The technology is still in the stage of experiment and testing, which is confidential and blocked back.


    The captain of the land-based aircraft carrier kept Chen Xin''s account in mind. Although he did not keep the existence of anti gravity technology confidential, he did the most rigorous protection for the anti gravity device itself, strictly preventing any foreigner from listening to their intelligence.


    Lucians also felt unable to this, and finally gave up spying on anti gravity technology. They just informed their officials and senior management of the matter and let the senior management find a way to talk about it with Yanguo. As soldiers who reinforced the European battlefield, they paid more attention to how to complete the reinforcement task.


    According to the results discussed by the high-level leaders of the two countries before departure, the troops of their brigade are not directly used to put on the frontal battlefield of the European battlefield. They will be more used as a teaching force to help European countries form armies that can resist the invasion of alien organisms and use their own strength to resist the alien organisms invading Europe from the Mediterranean.


    As for the problem of insufficient combat power, it will not be a problem with Yanguo''s 3D printing equipment.


    Previously, in Lucia, the land aircraft carrier not only made two land transport ships with the resources provided by the lucians, but also made exoskeletons and electromagnetic rifles that can be equipped with all three regiments, so that the force has been fully filled.


    European countries have already received the notice sent by Yanguo and Lucia. They have already prepared resources and mining areas, waiting for them to arrive, so as to provide countries with weapons and equipment that can effectively kill alien organisms.


    But for European countries, the captains of land aircraft carriers have no good impression. In recent years, European countries have never stopped targeting and discriminating against inflammatory countries.


    Now, of course, they are asking the burning country to save them, but what are the faces of these old Europeans? The captain knows a lot from the diplomats accompanying the ship. Whether they will secretly make a trip or make any small moves is unknown but must be guarded against.


    As the commander of the whole fleet, the captain must make all preparations for this.

 Chapter 729

    As the land fleet gradually approached Europe, European countries were eagerly looking forward to the arrival of the joint fleet of Yanguo and Lucia.


    Although there is only one brigade, which is like a drop in the bucket for the current European battlefield, the equipment and technology they carry are undoubtedly the greatest support and help to the European battlefield.


    For the current European countries, although the military strength is tight, it is not enough. What really bothers them is that light weapons have no lethality to alien creatures.


    These Europeans do not have the good comprehensive strength and luck of Yanguo. Chen Xinyuan constantly provides all kinds of advanced military equipment, and has sufficient production capacity to mass produce these advanced military equipment and equip them to the army.


    Their military equipment is still in the state before the disaster. Although it is not backward, and many military equipment are quite advanced before the disaster, it is obvious that these equipment are not suitable or suitable for fighting alien creatures.


    Although it is said that these Europeans were also military powers in those years, and their overall strength is not weak now, it is a pity that the two world wars have already drained the blood of these Europeans.


    Especially after World War II, the shift of the world''s focus and the rise of national movements led these old European powers to lose their vast colonies and could not recover themselves by sucking blood from the colonies as after World War I, so that in the half century after World War II, the life of European countries was not very good.


    As for the subsequent wave of European refugees, it can only be regarded as throwing another handful of salt on the wounds of these Europeans.


    This global disaster is more like stabbing another knife into the wound, or stabbing it with a blunt knife. Don''t pull it out after stabbing, and slowly bleed with a blood tank.


    In order to preserve its own people, English gave up its native land in exchange for the opportunity to merge and coexist with France. However, the Gauls'' own territory is also dominated by plains, which created France the strongest Knight country in Europe at that time in the era of cold weapons in the middle ages, but now it also makes France unable to resist the rising sea level.


    You should know that the average altitude of the whole western European Plain is even less than 200 meters. The people of England and France can only avoid the central plateau and the Alps in the southwest of France and build their shelters.


    However, after the alien creatures launched an attack from the Mediterranean, it made them complain incessantly. After all, after losing the territory in the north, the two countries can only withstand the invasion of alien creatures and have no strategic depth.


    As for the two countries on the Iberian Peninsula, they can only hold each other for warmth at this time.


    Although the terrain of the Iberian Peninsula is high and will not be submerged by the rising coastline, neither of the two countries is a powerful country. Their economic strength is limited, and their national strength can only be described as poor and weak. They have long lost the arrogance of Spain ruling the eastern hemisphere and Portugal ruling the Western Hemisphere.


    If it were not for the towering terrain, the whole Iberian Peninsula is a plateau. For the time being, relying on the terrain to block the attack of a wave of alien creatures, I''m afraid these two countries would not exist now.


    The rest of Europe... The Balkans have been occupied, and the Apennine peninsula is not much better. Only a few mountains close to Germany are still in the hands of mankind and barely maintain the defense line with the support of Germany, Britain and France.


    Although the Eastern European countries have not been invaded by alien creatures, it is a pity that they themselves do not have much national strength.


    After the disaster, although they had a fairly vast land, they could not even build shelters for their nationals, so that now the Eastern European countries have existed in name only. Even if there are survivors, they are unable to provide any help for the war.


    On the contrary, the Nordic countries had determined at the beginning that they could not withstand the severe cold after the disaster, so they also studied English, gave up their original land and threw themselves into the embrace of Germany.


    Relying on the population and resources brought by the Nordic countries, Germany has become the best European country in this disaster.


    And after the alien invasion, because there were a series of Mediterranean coastal countries ahead, Germany was not attacked by alien creatures.


    This also enabled the Germans to give full play to their industrial advantages and provide equipment and materials for the armies of other countries struggling to resist the invasion of alien organisms.


    However, even so, it was very difficult for them to resist. If it were not for the limitation of terrain factors, which led to the relative limitation of the attack of alien creatures, I''m afraid France would have fallen at the moment.


    But even so, the territory of the French is now divided into two parts: the central plateau and the Alps. The original Rhone River Basin in the middle has been broken by alien creatures, directly dividing the only remaining southern territory of France into two parts.


    French people really want to play their traditional art, but it''s a pity that aliens don''t understand the meaning of French military ceremony, so that this traditional art can''t play a role.


    However, this also ensures the bottom line of the morale of the coalition forces of European countries. After all, it is unacceptable for any human to lose or be bitten to death by alien creatures.


    Before the complete collapse of the army, everyone can still resist.


    It''s just a pity that European countries now have no effective way to curb the offensive of alien creatures except using heavy weapons and large caliber machine guns.


    In addition, the industrial production capacity of all countries is basically on the street, and it is not easy to supplement heavy weapons. The English people have begun to use their remaining nuclear weapons.


    After the light weapons, as the main weapons of the army, have lost their function, it is undoubtedly a severe test for European countries to rely on heavy weapons to beat back the tide of alien creatures.


    You know, these Europeans don''t have exoskeletons, power armor, Titans and electromagnetic rifles, nor do they have cold clothes that can withstand tens of degrees below zero, let alone energy towers that can heat an entire shelter or city.


    In addition, the dust clouds in Europe have not dispersed. They have been suffering from food shortage since the disaster.


    On the front line, these Europeans seem to have returned to the trench war of World War I. in hunger and cold, they can only rely on earthworks to resist the attack of alien creatures that don''t treat their lower offspring as life at all.


    Under such circumstances, Yanguo said that it can provide electromagnetic rifles that can effectively kill alien creatures and exoskeleton protective clothing that can enable soldiers to have a certain protective ability and resist the severe cold, which is a real help in the snow for these Europeans.

    With communication satellites, the fleet arriving in Europe will have less trouble to communicate with China.


    Although the transmission of signals will still be affected by dust clouds, it is not impossible to establish stable ties with China.


    After the fleet arrived in Germany, they soon sent back information to the country.


    In addition to informing China of the war situation and situation on the European battlefield, it also conveyed to China the help from German officials and the appeal of the alliance formed by European countries to obtain a series of powerful equipment such as power armor and Titan from Yanguo.


    The high-level has long expected that the alliance composed of European countries hopes to get help from Yanguo and obtain a series of powerful equipment such as power armor and Titan.


    Not only expected, but even the foreign trade version of power armor, Titan and even land-based ships intended to meet the demands of European countries and trade with them. In fact, the senior management has already been prepared.


    However, the top management did not pay attention to what to exchange from European countries with these things.


    What do European countries have to attract domestic things that are worth exchanging for these powerful equipment at home? Of course, there are some answers.


    Although some of the unique technologies of European countries are part of the domestic market, the rest are not attractive to the domestic market.


    Now, unlike before the disaster, we can talk about economic cooperation and other things before the disaster, but now there are no economic exchanges between countries all over the world due to the interruption of traffic and communication. Talking about economic cooperation can only be a dream, or just a cake to satisfy hunger.


    Of course, European countries also know this, so in addition to taking some science and technology at the bottom of their box as bargaining chips and hoping to exchange assistance from Yanguo, they also said that as long as Yanguo is willing to lend a helping hand, they are willing to meet any reasonable requirements of Yanguo.


    In fact, even if it is unreasonable, there is no choice for European countries now.


    Agreeing to the requirements of Yanguo will pay a certain price, but at least you can survive.


    But if you don''t agree, it''s hard to say. Although Yanguo can provide exoskeletons and electromagnetic rifles for everyone''s sake, so that European countries can resist the invasion of alien creatures, so that they won''t beat Europe too soon, it''s just that.


    The reason why Yanguo and Lucia are willing to help Europe is mainly based on the idea of allowing European countries to block alien creatures from the Mediterranean and avoid their own two-line war.


    But if European countries are really useless, or still want to do something at this time, it is not an impossible option for Yanguo and Lucia to give up European countries.


    Although this will bring great trouble to the two countries, according to the plan given by the lucians, they can rebuild the defense line established in Eastern Europe in the suvian era and use it as a basis to resist the attack of alien creatures.


    As for manpower, lucians have begun to gather the people of Eastern Europe and are trying to reorganize them.


    Lucia did not hide this from European countries, and even the Lucia officials who arrived in Germany with the fleet directly told European countries that Lucia could receive and resettle refugees that countries could not resettle.


    In the face of Lucia''s attitude, European countries have no choice but to choose cooperation and cooperation between Yanguo and Lucia.


    Only European countries are willing to agree to the conditions of Yanguo, but Yanguo doesn''t know what to want.


    In order to discuss this matter, the high-level also held a video conference, hoping to listen to the opinions of all parties.


    "There are not many things that European countries can take out now. Besides technology, academician Chen, what do you think we should exchange with them?" a senior official asked Chen Xin at the meeting.


    As the developer of these important technologies and an important domestic scientific researcher, Chen Xin''s opinions are very important in the view of senior management.


    However, facing the high-level inquiry, Chen Xin thought about it and asked, "can European countries open mining areas to us and let us mine ore?"


    "Mining ore? That''s OK. Although European countries are now making full efforts to produce military equipment for fighting against alien creatures, they have lost a lot of people and industrial equipment, and many mining areas have been abandoned." diplomats of the European Fleet connected by video at the other end replied quickly.


    "But China is the same now? Many domestic mining areas can''t operate. Is it necessary to send someone to Europe to open mines?" another senior official put forward a different view at this time.


    At this time, the situation of Yanguo is indeed as the official said. Although there is a shortage of resources in China, it is mainly because of the climate that a large number of mining areas are not exploited at all.


    If a country has surplus manpower, isn''t it more economical to mine directly in its own country than to mine in Europe and then transport it back?


    However, regarding this question, Chen Xin explained: "I don''t mean to send people from home to mine minerals, but to ask the fleet to collect refugees in Europe and then use these refugees to mine minerals.


    In this way, on the one hand, these refugees can be organized and turned into available manpower. On the other hand, they can also obtain resources to allow the fleet to directly produce all kinds of materials in Europe, and even transport some materials back to China to support domestic production and construction. "


    Hearing what Chen Xin said, the senior management immediately became interested. After several senior officials discussed it, they all felt that this was really a good plan.


    They use their people to open their mines on their land, and then they have to buy the equipment they produce. They have to thank us later. This is really a very worthwhile business.


    "That''s a good idea. There are 3D printing equipment on the land aircraft carrier. As long as there are sufficient resources, production and construction will not be a problem, which can better support the European battlefield and make these Europeans support longer." a senior official said with great appreciation and asked the diplomats of the fleet: "Will Europe agree to this plan? If you follow this plan, how many refugees can you collect in Europe and ensure production and output?"


    "Yes, there are a lot of refugees in Europe now. Most of them come from countries along the Mediterranean coast that have been attacked by alien creatures. However, now European countries are unable to host them. Most people can only find a place to settle down in the city and then freeze to death in the lack of food and clothing." here, the diplomats of the fleet can''t help feeling a little compassionate: "If we can close them, we can ensure production and output by matching the mining areas promised to us by European countries."

 Chapter 731

    After establishing a stable communication connection with the European Fleet, domestic and fleet contacts became more and more frequent.


    Because a large number of equipment are mainly developed by Chen Xin, the fleet also needs to consult and communicate with him on some technical issues.


    "We are now stationed in Ruhr Industrial Zone in Germany. Germany has provided us with the first batch of materials. Using these materials, we have built infrastructure and started to produce the first batch of exoskeletons and electromagnetic rifles." through satellite video phone, engineers and technicians of the fleet are reporting their current work progress to Chen Xin.


    After the fleet arrived in Germany, the Germans naturally felt overjoyed. Their first thought was to fill the battlefield with this powerful reinforcement force to withstand the pressure from alien creatures.


    However, it is obviously impossible for the fleet to be at the mercy of the Germans. After putting on a posture, backed by force and several rounds of negotiation efforts by diplomats, the fleet stationed in Ruhr Industrial Zone, built infrastructure based on the mining of local minerals and materials provided by the Germans, and used it as the logistics base of the fleet.


    Now the fleet is starting production through the built infrastructure and 3D printing equipment. Although the 3D printing equipment is mainly printing infrastructure components, it also began to produce some exoskeletons and electromagnetic rifles in small quantities and provided them to the German army nearest to them.


    "How did the German side respond to this batch of equipment?" hearing that the technicians said they had begun to produce exoskeletons and electromagnetic rifles, Chen Xin was also very concerned about the feedback after the Germans used these equipment.


    This is the first time that the equipment developed by Chen Xin has been handed over to foreigners for use. He would like to know whether the equipment he designed is practical for foreigners, or where they think they need to adjust and modify.


    Facing Chen Xin''s inquiry, the technicians quickly replied to him: "the German side is very satisfied with the equipment we provide, especially the electromagnetic rifle. They hope that we can provide them with drawings so that they can also produce this rifle to equip the front-line army against alien creatures.


    However, the Germans do not seem to attach importance to the exoskeleton. Although they have received and equipped the exoskeleton we provided to the army, from the feedback provided by the Germans, they feel that this kind of equipment is not practical and consumes too many resources. It is better to produce more electromagnetic rifles. "


    "The Germans actually think so? Are they dissatisfied with exoskeletons? Or do they think exoskeletons are impractical?" Chen Xin was confused by the German idea.


    "No, in fact, the Germans are also satisfied with the exoskeleton, but the problem is that the materials in Europe are very tight, and all resources have to be used for the production of war weapons. The Germans think that the exoskeleton consumes too many resources." the technicians couldn''t help but feel a burst of laughter and helplessness when they mentioned this, and explained to Chen Xin: "The resources consumed by a set of exoskeletons can produce three electromagnetic rifles. If only electromagnetic rifles are produced, the same resources can equip four soldiers, but if exoskeletons and electromagnetic rifles can only arm one soldier, which is too expensive for the Germans. They don''t have enough resources to invest so extravagantly."


    Hearing the technicians say so, Chen Xin understood that at the same time, he also deeply felt helpless.


    European countries, to put it better, are western developed countries. To put it worse, a group of naughty people have settled down. Both industrial production capacity and infrastructure capacity have lagged far behind that of China. In terms of resource output, they relied on imports from other countries before the disaster.


    Now, after they have lost the import of resources, it is difficult for them to meet their consumption only by relying on the output of local resources, let alone cope with a war.


    Especially after the disaster, countries have lost a lot of industrial capacity and less resource output.


    If not for the fact that European countries have finally united in the face of alien invasion and used all kinds of resources together, I''m afraid they would be even worse than they are now.


    Thinking of this, Chen Xin can only reluctantly shake his head and say to the technicians: "we don''t care how the equipment is used for them. You are only responsible for processing the supplied materials and producing equipment so that they can withstand the attack of alien creatures."


    "Don''t worry, academician, the country has formulated relevant plans and coping strategies before coming, and we won''t delay things." the technician said to Chen Xin, who seemed very confident about this.


    Chen Xin doesn''t doubt whether the European fleet can complete the task, but he still asked the technicians: "did they distribute the weapons and equipment you gave Germany to other countries? Or did they send their troops to the front line to resist alien creatures after they equipped their own troops?"


    This is also the key concern of Chen Xin. Yanguo sent a fleet for support. Although it uses their materials for production, it hopes that they can improve their combat effectiveness and resist the invasion of alien creatures.


    If the Germans only armed themselves with equipment, hid in the rear and watched people from other countries in front fight with alien creatures, Chen Xin could not accept it anyway.


    "Academician Chen can rest assured that we will not sit idly by and watch this happen." facing Chen Xin''s concerns, the technicians assured him confidently: "comrades in the diplomatic field have begun to get in touch with English and France, and we have assigned a land ship to contact them.


    In addition, on the German side, although they have not sent troops equipped with electromagnetic rifles and exoskeletons to the front line, it takes time to master the new equipment, and they also sent a small number of electromagnetic rifles to the front-line troops, which should be to test the actual effect of these weapons on the battlefield. "


    "It''s hard for you. You should also pay attention to your own safety in Europe. While being wary of alien attacks, you should also be careful of those European guys. In the past, they dared to take our things. Now in this environment, you should pay more attention to guard against their greed." Chen Xin really has no good impression of those European guys, so he is also particularly wary of them.


    However, this is not a groundless worry for Chen Xin. After all, in this environment, European countries can only be said to be struggling to survive. If they take risks, no one can tell.

 Chapter 732

    After the call with the European Fleet, Chen Xin is also ready to go home from work.


    Recently, all kinds of work in the Dome City have been on track. The theater is stable because of the entry of the land fleet. Chen Xin is not so busy and can enjoy the treatment of getting off work on time.


    Leaving the office building, Chen Xin walked home.


    Because the dome has been completed, now the dome looks more like a well planned city than the unfinished refugee camp when Chen Xin and his colleagues first moved in.


    Relying on the energy tower heating the whole dome, the temperature in the dome is maintained at about 10 degrees, so you don''t need to wear protective clothing even outdoors. You only need to wear protective clothing when you leave the dome and go outside the dome.


    With a suitable temperature, Chen Xin''s clothes are more in line with the current temperature. He is just a set of ordinary work clothes and a coat. He looks no different from other staff who are also off duty.


    If people who know Chen Xin pass by and greet him from time to time, it is estimated that if ordinary people don''t know him, they can''t see that Chen Xin is the top person in charge of the Dome City and one of the important scientific research forces in Yanguo at the moment.


    Chen Xin himself didn''t care about it. He greeted others friendly and didn''t think he was special.


    Before the disaster, he may feel that he needs to show his holiness in front of others. Otherwise, what''s the significance of traveling at night in royal clothes.


    But in today''s environment, it''s too boring and low-grade to pursue any pomp and style, and play with the routines such as making people show their holiness in front of them.


    For Chen Xin now, instead of spending time and energy on pursuing independence, it''s better to think about how to develop new equipment, so as to solve the problem of alien creatures earlier.


    Because Chen Xin lived not far from the office building, it was only a few minutes for him to walk home, so he didn''t let anyone drive him or anything else. Only a security guard followed him as a security guarantee.


    Although Chen Xin is theoretically not dangerous in the Dome City, there should be security measures.


    After all, no one can guarantee that if a psychopath can''t think of attacking Chen Xin? Although Chen Xin can call out his nano armor at any time, what if he doesn''t react?


    Important researchers like Chen Xin are terrified even if they are just frightened.


    Therefore, security personnel should be equipped. Even if they can''t play a great role, it''s good to use them as service soldiers for Chen Xin.


    However, today, the security guard behind Chen Xin felt that he could play a role, because on Chen Xin''s way home, someone had been following behind them with a seeming intention.


    While the security personnel raised their vigilance, they also touched the gun at their waist.


    Now it''s a time of war. All security personnel wear guns directly at their waist and can draw guns directly without any cover.


    This is not only to facilitate the rapid response of security personnel, but also a deterrent.


    However, now the deterrence seems to have no effect. Starting from the door of the office building, the people behind Chen Xin seem to have made up their mind. Suddenly, they took two quick steps and trotted towards Chen Xin.


    It doesn''t look special. It''s like someone meets an acquaintance on the road and wants to say hello, but in the view of security personnel, it''s a security threat.


    So when the man who ran over reached out to Chen Xin as if he wanted to shoot him and was about to open his mouth to say something, the security personnel grabbed the man at the first time and pressed the man on the ground after a trip.


    Chen Xin noticed this change. Before he reacted, the man had been pressed on the ground.


    "Pain! Brother Chen, it''s me! Bruce Lee! Misunderstandings are all misunderstandings! Let go of me! My hand is about to break!" the pressed man quickly shouted for help and looked up and shouted at Chen Xin.


    When Chen Xin heard the cry, he looked closer, smiled and shook his head, motioning the security personnel to let go of the man. And said to him, "Bruce Lee? What''s the matter with you? You don''t need this way to find me? Suddenly, I wonder why terrorists!"


    "Wronged! What a great injustice! How dare I attack brother Chen! I really have something to find you, but I can''t find you, so I have to squat here." Li Yulong, who was released by the security personnel, got up from the ground, patted the dust on his body and explained to Chen Xin.


    At the same time, Li Yulong didn''t forget to move a few steps aside, as if he was avoiding the security personnel.


    Looking at Li Yulong, Chen Xin smiled helplessly, but he was in a good mood.


    For Chen Xin, he has not seen Li Yulong and his old friends for a long time. Now he can see that Li Yulong is the same as before and has not changed much. Naturally, he is very happy to meet his old friends.


    However, looking at Li Yulong''s slightly old clothes, Chen Xin couldn''t help frowning slightly. It seems that Li Yulong doesn''t live very well.


    This made Chen Xin feel a little strange. Li Yulong''s family was originally a rich businessman. Although it was a great blow to their family engaged in the hotel industry after the disaster, Chen Xin remembered that he had given Li Yulong a lot of help before, helped him have a relationship with the municipal government and the municipal police station, and he also set up a trading market himself. It is reasonable that he should not be so miserable.


    Thinking of this, Chen Xin couldn''t help looking up and down at Li Yulong and asked him, "Bruce Lee, what''s the matter with you coming to me? It''s embarrassing to see you like this!"


    "Don''t mention little brother Chen, I''m bitter!" hearing Chen Xin''s words, Li Yulong immediately felt the same sadness and complained to Chen Xin: "Since I moved to the dome new city, my family''s business has been lost, and my men have run away. I can''t live any longer! If the state doesn''t distribute rations and supplies, I''ll starve to death. Brother Chen, you have to help me!"


    Listening to Li Yulong''s complaint, Chen Xin didn''t feel that he was miserable, nor did he raise any sympathy, but he couldn''t help but raise a burst of smile at the bottom of his heart.


    Li Yulong deliberately pretended to be miserable in front of him to win his sympathy so that he could help.


    When Li Yulong asked him for something, he played this set. He always pretended to be miserable and didn''t bring a heavy sample.


    However, Li Yulong has a good sense of propriety. Although he plays miserable and sympathizes, he never offends people or makes unreasonable demands. The so-called playing miserable is just to make others more inclined to him and easier to be persuaded by him.


    So Chen Xin doesn''t mind helping him. As long as he doesn''t go too far, Chen Xin is still willing to help for the sake of his friends.


    "What do you want me to help you?"

 Chapter 733

    Li Yulong and Chen Xin found a place where they could sit down and talk about things and were ready to have a good chat.


    The place they are looking for is a public canteen in dome new town, which originally belonged to one of the characteristics of Yanguo in the last century, but gradually eliminated with the changes of the times.


    However, with the change of social environment after the disaster, this kind of public canteen gradually flourished.


    On the side of dome new town, there will be such a public canteen in almost every block to provide food for the people.


    At first, the state directly distributed physical goods as the reward for people''s labor, but later, as everything gradually got on track, the distribution of physical goods was too cumbersome, and some food was not easy to preserve. Ordinary people now have no refrigerator at home, and public kitchens should be used in shelters


    For many reasons, the issuance of physical goods was cancelled and meal vouchers and other bills were issued instead. Everyone went to the public canteen to eat with meal vouchers.


    The canteen can provide people with more delicious meals than standard emergency food because of the adjustment of material supply.


    There were not so many public canteens in the original shelter, but when the people of the whole city moved to the dome new city, every family had no kitchen, and people''s eating became a big problem. Only by opening a large number of these public canteens, the municipal government solved the problem of eating for more than 100000 people.


    These canteens are built according to unified standards. Each canteen can accommodate at least 500 people to eat at the same time, and can provide meals for 3000 people within two hours. In dome new town, there are at least more than 30 such public canteens.


    At this time, it''s the meal point. Although it''s just time to get off work, there are already many people waiting in line in the canteen.


    Although Chen Xin said he could go home for dinner, since Li Yulong came to ask for his help, he didn''t mind saying that he could spare a meal and listen to what he wanted to say.


    Li Yulong went to the dining table of the canteen very attentively and came back with two meals. Since he was asking for someone to do something, he had no possibility of letting Chen Xin go to fetch meals himself.


    After taking the food back and sitting down, Li Yulong said to Chen Xin, "brother Chen, you have to help me! I''ve really had a hard time these days!"


    "It''s no use just complaining. Tell me what happened to you these days. If it''s really miserable, I can''t help you!" Chen Xin didn''t take Li Yulong''s complaining seriously.


    Based on his understanding of Li Yulong, Li Yulong may indeed have a hard time these days, but what''s the matter? Their family background is still there, not to say that they can''t live.


    Moreover, the state has been distributing basic living security materials to ordinary people. Even if they have no ability to work and can''t exchange their labor for food and other living materials, it''s not impossible to say that they can''t live.


    So Chen Xin just ordered Li Yulong and looked at him in his spare time to get him to the point.


    Hearing what Chen Xin said, Li Yulong also knew that it was no use selling miserably, so he changed a more serious expression and said to Chen Xin: "little brother Chen, although what I said is a little exaggerated, our family''s life is really difficult.


    After moving to the dome new town, my family lost almost everything and lost the business you took care of me before, brother Chen. Although you helped to establish a relationship with the municipal government and the municipal police station, dad still has a lot of contacts.


    But my family still lost a lot of things and business. Many people who used to work with my family have left. It''s really difficult. That''s why I want to come to brother Chen and see if there''s anything I can do. "


    When Li Yulong finished, he looked forward to Chen Xin and hoped that he could give a positive reply.


    However, after listening to Li Yulong''s words, Chen Xin just bowed his head and remained silent for a long time before he asked Li Yulong, "what do you want to do? If you just want to find a job, there are important people everywhere now. I can arrange a better job for you, but there is no problem at all.


    But isn''t this what you want? What about the trading market you used to do? Even if you move to dome new town now, your foundation in this field should still be there? It shouldn''t be difficult for you and your family to reopen?


    Tell me your real purpose. If it''s not too much, I can''t help you. "


    "You''re not holy without brother Chen!" Li Yulong quickly flattered Chen Xin, and then explained to Chen Xin: "I don''t have a business in the trading market without the care of brother Chen. I can only survive by selling fruits and some materials.


    Since I moved to the dome, I can''t grow fruit. It''s impossible for the municipal government to grant me land to continue growing fruit, so the business is much worse. Now it''s basically reduced to the black market of the stall. "


    At this point, Li Yulong paused, and the expression on his face looked very disappointed.


    Although the trading market he had set up before was built with the help of Chen Xin and the shadow of his parents, he always said that it was a career he worked hard to break out.


    Originally, although the business was not so prosperous, it was also booming and gradually had a stable basic market.


    But who would have thought that with the invasion of alien creatures and the overall relocation of the city, Li Yulong''s foundation suddenly turned into nothing.


    In the face of such a blow, Li Yulong certainly wants to give up. After all, his father is still at home, and his past contacts can still go through. As long as Li Yulong is willing to manage well, he can''t live on.


    But if Li Yulong is willing to live on the capital left by his parents, he won''t want to make a career by himself.


    Because he is unwilling, because he wants to prove himself, because he wants to make a career, and is unwilling to follow the route planned by his parents, Li Yulong will come to Chen Xin and hope to get some help from him.


    In the face of Li Yulong''s remarks, Chen Xin''s feeling is slightly subtle, but he can also understand it.


    I''d rather ask for friends and owe people, than ask my parents, just to prove myself in front of my parents. Chen Xin has had such a mentality.


    "If you want to do something, I really have a job here, but the job is very dangerous. Do you have the courage to take risks?" Chen Xin thought of a thing he planned to do recently, so he offered Li Yulong an opportunity.


    Facing Chen Xin''s inquiry, Li Yulong nodded hard and said firmly, "now in this world, what don''t you take risks? Brother Chen, you say, as long as I can do it!"


    "OK, come to my office tomorrow and let you do something." Chen Xin saw that Li Yulong''s attitude was firm, so he nodded and agreed.

 Chapter 734

    The next day, excited by Chen Xin''s promise to work for himself, Li Yulong, who was almost awake all night, changed his serious and clean clothes and waited in front of the office building early in the morning.


    Chen Xin didn''t keep him waiting, so he quickly called him to his office.


    "Little brother Chen!" Li Yulong greeted Chen Xin and straightened his body, hoping to make himself look more energetic.


    Looking at his appearance, Chen Xin nodded with satisfaction. Then he said, "sit down and don''t stand."


    Li Yulong sat down according to his words. Only then did he notice that there was a science fiction model on Chen Xin''s desk.


    "Brother Chen, you said yesterday that you had a job for me to do. What kind of work is it?" Li Yulong asked Chen Xin directly without politeness after sitting down.


    Although it is said that Chen Xin''s status has opened a gap with Li Yulong, Li Yulong does not show much formality in front of Chen Xin, but is very close.


    Chen Xin doesn''t feel any offense to this. Instead, he appreciates Li Yulong''s attitude. If he shows restraint and alienation, Chen Xin will feel uncomfortable.


    Therefore, after Li Yulong asked, Chen Xin didn''t talk nonsense. He just pointed to the model on the table and said, "what you want to do is related to this. Do you know what this is?"


    "It looks like a transport vehicle, but it''s a little different. Brother Chen, do you want me to deliver goods or run logistics?" Li Yulong glanced at the model on Chen Xin''s desk, thought a little and guessed what Chen Xin wanted him to do.


    "Yes, it''s really related to transportation and logistics." Chen Xin nodded to confirm Li Yulong''s guess, and then explained: "you know about the invasion of alien organisms, but not only China, but also Europe.


    Therefore, some time ago, China sent a group of reinforcements to Europe to reinforce Europe with the reinforcements sent by Lucia to support European countries against the invasion of alien organisms.


    Although the troops themselves carry a lot of supplies, they also have a certain self-supporting ability, and European countries will also provide material support, considering the complex situation and environment in Europe, China still plans to establish a logistics channel between domestic and European assistance forces.


    On the one hand, it is to be able to provide material assistance to the troops, on the other hand, it is also to transport the resources obtained by the troops on the ground back to the country. "


    Speaking of this, Chen Xin paused and gave Li Yulong some time to digest what he said before he continued: "because the traffic is cut off and there is a lack of means of transportation in China that can travel such a long distance and have a large volume of traffic, so this matter is handed over to me.


    I told you that there is work for you to do. That''s what I said... Of course, important material transportation is a matter for the military. If you don''t intervene, you''re not qualified.


    The main person in charge of this matter is the military. Even me, what I can do is to put you into the transportation team to be responsible for the transportation of ordinary supplies. As for what you can do, it depends on your own play. "


    Seeing that Chen Xin had finished, Li Yulong didn''t immediately ask, but after carefully digesting what he said, he asked: "brother Chen, this transportation can be completed by the military alone? What do you mean by putting me in..."


    "If you can ask this question, it proves that you are suitable to do it." Chen Xin seems to be very happy that Li Yulong will ask this question, and smiles at him: "if it''s just transporting materials, the military can handle it by itself.


    Although the throughput will not be small after the logistics channel is established, and it will be a waste to use only military personnel to transport materials, it can still be done. The reason why I want to plug you in is actually for another thing. Can you think of what it is? "


    "Well... It''s obvious that people don''t need to participate in material transportation. Even if the military is short of manpower, the state can recruit enough available people. Brother Chen, you let me participate... Shouldn''t it be smuggling?" Li Yulong thought for a while and then tentatively said his guess.


    "Yes, it''s smuggling, but it''s not illegal smuggling, but using private channels to communicate with Europe when the state knows and allows it." Chen Xin confirmed Li Yulong''s guess and changed a more high sounding way.


    Hearing Chen Xin''s "translation", Li Yulong immediately understood the profound meaning.


    Obviously, as he said, pure logistics transportation does not need to engage in other fancy tricks. Chen Xin must have other purposes to put him into the transportation team.


    This purpose is exactly the smuggling mentioned by Chen Xin and him.


    If it is someone else, it may be strange that they are all officially opened logistics channels. Why should they smuggle?


    Now it''s not before the disaster. There are customs inspections. Europe is counting on the assistance of the inflammatory country to resist the invasion of alien organisms. What the inflammatory country wants to transport used to be a one sentence thing?


    As for what the inflamed country wants to bring back from Europe, do European countries dare to risk offending the inflamed country?


    Li Yulong had such doubts, but he didn''t ask directly. Instead, he asked Chen Xin, "is the country going to transport anything back from Europe?"


    "Bruce Lee, you should know that many sophisticated machining plants in Europe, including large enterprises, are privately owned?" Chen Xin did not directly answer Li Yulong''s question, but asked him a question.


    When Li Yulong heard this, he immediately showed a clear expression on his face. He didn''t need a heavy hammer to ring the drum. Chen Xin just clicked a little, and he already knew what he was going to do.


    However, although he understood his mission, Li Yulong asked with doubts: "in this environment, can those private factories in Europe continue to operate? What do I need to pay attention to? Do I have specific goals?"


    "We should always respect the inviolability of private property, and the Europeans make these factories subject to unified allocation by means of government procurement and provision of raw materials. Generally speaking, they can operate." for the "smuggling" plan, Chen Xin has obtained a lot of information from the diplomats of the European Fleet. He took out these information and put it in front of Li Yulong: "What you need to transport back has not been clearly determined for the time being. In short, it is what you transport. A special person will contact you about this matter, and I am only responsible for inserting you in.


    In addition, you should note that you are not the only participant in this plan. What achievements you can make depends on your own luck. "


    "I know. I won''t let you down, brother Chen!" Li Yulong took the information and looked very excited and excited.

 Chapter 735

    Smuggling, even with the support and permission of the state, is still a matter that can not be put on the table.


    In fact, if Yanguo openly asks European governments for what they want, in the current environment, nine times out of ten European governments are just wrangling and will not refuse.


    However, rather than wasting time arguing with those annoying and hypocritical politicians, the senior leaders of Yanguo obviously prefer to find a few white gloves and exchange some domestic surplus living materials for something they are interested in, such as high-precision machine tools and high-performance parts technology.


    After all, European countries are different from Yanguo. Many of their top technologies such as precision machining technology belong to private factories rather than countries directly.


    For example, it may be just an insignificant processing plant, which looks like a small private workshop in China, but it is possible and common to have the world''s top parts processing technology or master any world advanced patents.


    This kind of small factories can be seen everywhere in Europe. Many small factories have things that the senior management of Yanguo will be interested in, but they are too many, and the amount of things that the senior management is interested in is not large. Going to the national level will become a big procurement that can kill Logistics.


    Because of different regimes, in European countries, the real top technologies are not in the hands of the official, but in the hands of private companies or large enterprises. The official can only obtain the finished products of these technologies through procurement.


    So instead of going through the governments of European countries to quarrel, and then slowly go to these manufacturers to talk about technology acquisition, it''s better to pull a batch of white gloves and directly exchange with these factories in private.


    This way of spreading the net is familiar to Yanguo. When Subia disintegrated, Yanguo benefited a lot from the collapse and disintegration of Subia by relying on this way similar to smuggling and reselling.


    This has nothing to do with the rapid development of economy, military, technology and other fields in Yanguo in the next two decades.


    According to the prescription, the senior management of Yanguo quickly completed the preparations in this regard, and Li Yulong, who was stuffed into the action by Chen Xin, also completed the training of relevant businesses under the arrangement of Chen Xin.


    While everyone is ready, Chen Xin has also prepared a cargo ship to Europe.


    This time, Chen Xin is still preparing a land ship with anti gravity engine. However, because it is a cargo carrier, this cargo ship emphasizes the carrying capacity, and the hull is also upgraded by Chen Xin with a cargo ship.


    Also because it is a cargo ship, the hull structure is relatively simple, and the size is larger than other land ships.


    The size of the cargo ship is not smaller than the existing mobile base, but only smaller than the land aircraft carrier. However, in terms of tonnage, in order to carry more cargo, the cargo ship can be filled with 30000 tons of cargo when the cargo hold is full.


    There is no doubt that there is a big gap between the carrying capacity and the 220000 ton container ship that Yanguo could manufacture before the disaster, but considering that it is a land ship and can fly, this carrying capacity is quite acceptable.


    Naturally, the structure of the cargo ship is not as complex as that of an ordinary land ship, and there is no mobile base. It is also responsible for taking off and landing aircraft and carrying a large number of passengers. Most of the space of the whole cargo ship is cargo hold, but the cargo hold is also divided into upper and lower layers, which are respectively loaded with different goods.


    The lower cargo hold is mainly used to carry food, which is also one of the main assistance that the country feels can provide to Europe after comprehensive consideration.


    Although the previous alien invasion almost destroyed the ecological agricultural planting area established by Chen Xin and others in the Dongting Lake area, it is certainly impossible for such a large country to have only such a grain producing area, especially after the disaster.


    Therefore, the grain production around Dongting Lake has indeed been affected, and the material supply was tight for a time, but this does not mean that the grain production of Yanguo itself has been greatly affected.


    After several months, the grain in other areas has entered the harvest stage. For the time being, the state still holds a large amount of grain that can be used for foreign trade. In particular, even if the cargo ship is filled, it only needs 30000 tons of grain.


    Although 30000 tons is not a small number, it is not a large number for a country.


    Therefore, for Yanguo, it is a matter of benefit without cost to transfer some food to Europe in exchange for something they can see.


    Of course, the high-level prepared not only food for the cargo ship, but also a number of second-hand civilian exoskeletons, as well as some drugs and other goods that the high-level felt were in short supply.


    These things are the chips on the hands of Li Yulong and his group of white hands selected by the top.


    They will arrive in Europe with the cargo ship, and then contact a number of private factories with the help of European Fleet staff to trade with them in exchange for something of high-level interest.


    These white knuckles are no different from their father''s grandfather more than 30 years ago, but they are now working for the government.


    They also have no specific goals. What they can get from Europe depends on their own ability and luck.


    The senior management just sent a team of staff responsible for the evaluation to accompany the team. If they get anything good, they will take it back to these staff for evaluation. As long as they pass the evaluation, they can reach a deal.


    Each time they complete a transaction, these white-handed sets can obtain some points, which can allow them to exchange more chips and materials for trading from the rear, so that they can exchange more things.


    Compared with normal diplomatic channels and high-level exchanges with each other''s countries, such a transaction will undoubtedly be much more efficient and fruitful.


    Therefore, after having prepared all the goods, the crew members have been familiar with the operation of the cargo ship, and the white-handed sets have received the "settlement fee", the logistics team set out.


    For the sake of safety, the cargo ship will remain floating all the way, and for the sake of safety, a frigate will accompany it.


    Although the frigate is also a land ship, it will still use the navigation mode of keeping floating in the whole process to travel with the cargo ship.


    On the one hand, it is to test whether the anti gravity device can support long-term uninterrupted operation, on the other hand, it is also to make the crew familiar with this mode of action for the future.

 Chapter 736

    Things in Europe have nothing to do with Chen Xin for the time being after the cargo ship set out, and his daily work is free to some extent.


    Although the alien attack in the Dongting Lake theater is still surging, it seems a little weak in front of the increasingly stable defense line and the strong industrial strength after human adjustment.


    To fight against steel with flesh and blood, I''m afraid they would have been wiped out in the war if these alien creatures had not had a flood of numbers and not weak single combat effectiveness.


    After all, this is just a group of alien creatures that are not very powerful. They are neither alien insects nor talon. They don''t have such exaggerated combat effectiveness.


    Before, it was affected by environmental factors and the human industrial production model had not been adjusted, which allowed alien organisms to take advantage.


    Of course, if alien creatures could break through the blockade of the inflammatory army and expand themselves, under their amazing reproductive ability, they would spread like viruses, and their number would increase like geometric multiples.


    If this situation is really turned into, the army of Yanguo may be difficult to deal with more alien creatures than ants.


    However, fortunately, the army of Yanguo has blocked the expansion of alien creatures. They are firmly limited to the Dongting Lake area. Even if they plan to dig tunnels from the underground, they are not enough to see in front of human monitoring means and ground drilling and Strike ability.


    In particular, Yanguo has restored its contact with satellites in the sky. With the monitoring and guidance of satellites, the human military strike force has also returned to the normal level. A large number of over the horizon weapons let these guys who are still fighting by flesh know what the steel tracks roll forward.


    Although humans are not alien creatures crushed by the tracks of tanks, there is no doubt that these alien creatures are crushed by iron creations.


    In fact, after the restoration of satellite communication and military satellite functions, the situation of war with alien creatures has changed.


    Previously, due to the obstruction of dust clouds, the satellite guidance in the missile guidance mode undoubtedly became unusable. Therefore, the military can only use the missile by relying on the limited means of laser guidance and limited radar guidance of front-line combatants, as well as the inertial guidance of the missile itself. The strike accuracy and efficiency against alien organisms can only be considered unsatisfactory.


    It is unable to deeply control the battlefield situation, and the missile does not know where to fight, which can effectively prevent the attack of alien creatures. As a result, although the military holds a big killer, it can only be used within the distance between air reconnaissance and ground observation, can not achieve over the horizon attack, and can not achieve overall control of the battlefield.


    It doesn''t mean that missiles can''t be used without satellite navigation. As long as there are coordinates, these big killers can be launched by inertial guidance.


    However, without battlefield information, it is difficult to choose where these missiles should hit.


    The price of a missile is high. If it is only used to bombard the cannon fodder of those alien creatures on the battlefield, it will be too wasteful.


    Now, satellite monitoring is enough for humans to master every move of alien creatures on the battlefield. No detail or change can escape the eyes of the sky.


    The re launched satellite navigation system has also played a role again. As long as the satellite finds any bad tendency of alien organisms on the ground, the missile will hit the target under the precise positioning of satellite navigation.


    It was with the cooperation of the satellite that after mankind resumed contact with the satellite, the military had knocked out all the underground exits of alien creatures in the Dongting Lake area with a wave of missiles, greatly reducing the ability of alien creatures to transport cannon fodder to the battlefield.


    This not only reduces the total number of alien creatures on the battlefield to a considerable extent, but also effectively curbs the reinforcement of the battlefield by underground alien creatures.


    Although alien creatures can continue to dig new channels and send new reinforcements to the battlefield, such reinforcements can not achieve good results under the attack of missiles with precise satellite positioning and navigation.


    During this period of time, alien creatures have not tried to attack after digging along the groundwater layer and penetrating into the defense line, as before, but human beings'' mastery of the hydrological and geological conditions of this area allows them to effectively analyze the possible attack direction of alien creatures.


    In addition to the vibration monitoring system and the seismic network originally used to predict earthquakes, every action of alien organisms underground is monitored by humans.


    As long as the vibration monitoring shows that there are signs of danger escalation and alien invasion in a certain area, the land fleet that has been wandering around the battlefield will arrive in the area and carry out a strong and powerful force attack to directly destroy any possibility of alien creatures breaking out of the ground.


    Relying on the powerful air strike capability of landing aircraft carriers and the battlefield mobility of land-based ships, the whole fleet is active on the battlefield like a mobile fortress.


    Destroyers and frigates are active on the battlefield. As mobile forces, they provide fire support for the battlefield. When necessary, they can go deep into the enemy''s rear from the air, while land aircraft carriers patrol the battlefield most of the time according to the action route planned by the military to provide air strike force and intelligence support.


    Where there are signs of gathering of extraterrestrial creatures, the fleet will drive there. With missiles and aerial bombs, extraterrestrial creatures will be fully aware of the absolute gap between flesh and blood and steel and fire.


    Of course, alien creatures are not the passive victims. They also made many attempts during this period. For example, they sent giant flamethrowers that almost brought great trouble to the defense line to dig from the ground again, and then cooperated with a large number of combat daughters to attack the defense line.


    But this tactic is simple and rough for human beings.


    Not to mention the missile attack system that has been deployed around the battlefield, but the frigates in the land fleet wandering on the battlefield can directly kill this thing with naval guns.


    Compared with blanket bombing from the field of view with large caliber artillery, the frigate can fly near the giant flamethrower and break the skull of the giant flamethrower with the naval gun in the way of direct fire within the field of view.


    Of course, in most cases, land ships will not do so, but more use satellite monitoring and reconnaissance aircraft positioning, and then use missiles to kill this thing.


    Only when these big guys are too close to the defense line will the land ship approach in the way of air flight and hit directly with ship guns.


    It is precisely by this series of means that alien creatures are no longer a huge threat to Yanguo, but have become a controllable situation.


    With the decline in the number of soldiers killed in the defense line, the military even has the idea of turning this place into a round war, turning alien creatures into a sharpening stone for its own army.

 Chapter 737

    The domestic war against alien creatures has gradually occupied an advantage, but this is not the case in Europe.


    Because of the gap between weapons and equipment, the difficulty of light weapons to cause damage to alien creatures, and the constraints of environmental factors, it is particularly difficult for Europeans to resist the attack of alien creatures.


    Therefore, after the arrival of the joint reinforcements of Yanguo and Lucia, European countries, after understanding the combat effectiveness of this force, urgently hope that this reinforcement force can quickly reinforce the frontal battlefield and share their pressure.


    At the request of European countries, after the lucians of the reinforcements discussed with the Yanguo people, the lucians sent four of their two regiments and six battalions, and Yanguo sent two battalions together to go to the frontal battlefield to support the operations of European countries.


    The remaining two Lucia battalions and a state-run army remained to defend the land aircraft carrier and the established logistics base.


    With them are two transport ships and a frigate carrying them. Three land ships will be used as fire support and their mobile stations. Two mechanized infantry regiments will be filled into the battlefield in the southwest of flange.


    Before the reinforcements arrived on the battlefield, they thought that the alien creatures on the European battlefield should be similar to those encountered by the inflammatory country. The two may only be different in scale and quantity.


    European countries are unable to resist the attack of alien creatures, which is more caused by the inability of light weapons to cause effective damage to alien creatures.


    However, when they really arrived at the battlefield and participated in the war against alien creatures in European countries, they found that they took it for granted.


    Although it is true that the Military Morality of European countries has declined in recent years and there has been little brilliant performance in the war, there are still some foundations in old Europe, and advanced military equipment is not absent.


    Although light weapons can''t cause damage to alien creatures, heavy machine guns, flat anti-aircraft guns and heavy artillery are still useful.


    Old Europe would not say that these things could not be taken out again. It was so embarrassing that it could barely resist the attack of alien creatures only by relying on terrain restrictions.


    Originally, Yanguo and Lucia thought it was due to environmental factors. The weather was too cold to give full play to the combat effectiveness of these soldiers.


    But when they came to the battlefield, they realized that although old Europe did pull its crotch and the environment and climate did limit the combat effectiveness of their soldiers, the main reason why old Europe was almost unable to resist the attack of alien creatures was that alien creatures were more visible to the naked eye.


    Not to mention the common cannon fodder such as combat daughter and worker ant daughter. The giant fire spitting daughter that only occasionally appears in Yanguo is almost a conventional arms here. The most conspicuous ones on the battlefield are the plural big guys.


    Along with it, there are obviously larger capsule and bubble bodies than those that have appeared in the Dongting Lake theater, with longer spraying distance, and even the same kind with two gun tubes, as well as the most incredible air units.


    "Are they really just a creature? Even insects can''t differentiate so much?"


    The pictures taken in the European battlefield were sent back to China, which shocked everyone. Many biologists even felt that the three views were broken.


    At the urgent discussion meeting, Chen Xin looked at the alien creature that was like a swarm of insects in the game. He shook his head: "even if ants can differentiate into worker ants, soldier ants and flying ants, alien creatures are too much!


    They are more like a biological weapon than a biological group. Everything they have is more like evolution for expansion and aggression, and nothing like changes made for survival. "


    "Yes, nature is the cruelest. Any useless or cumbersome design will be eliminated in nature. Only one species will develop in other directions after getting rid of the pressure of survival.


    According to Occam''s razor rule, if they just want to survive, they don''t need such an exaggerated body shape, nor do they need to be able to fly, nor do they need to spit fire. These are things that have nothing to do with their survival or their niche! "A biologist also agrees with Chen Xin, He also felt that this did not look like a normally evolved biological population.


    At this time, another biologist said, "so this is not an alien group we judged before, but a biological weapon. Are there aliens behind them?"


    "Aliens may not, or they are aliens themselves." Chen Xin shook his head and didn''t think there were aliens behind these alien creatures: "don''t forget that behind these alien creatures, there are superior descendants we haven''t seen so far. I seriously doubt that this is an alien civilization taking the route of biological evolution."


    "Is it possible for an alien civilization to follow the route of biological evolution?" a scientific researcher attending the meeting felt incredible. He thought that civilization should follow the route of science and technology rather than physical evolution.


    "The universe is so big that there are no surprises. Don''t forget that Bluestar was once ruled by insects. If an insect took the route of evolutionary brain at that time, the emergence of insect people was not unacceptable." perhaps because of the experience of an online writer, Chen Xin was very receptive to this point: "If this alien creature is stimulated or influenced in the process of evolution, it is not impossible to form a situation similar to that of collective intelligence or superior intelligence individuals controlling low intelligence individuals.


    However, the focus of our discussion today is not how they evolved, or why they evolved like this. After we destroy them, we have time to study this. Now we should pay more attention to the European battlefield. "


    "Yes, the European battlefield is like this. It seems that European countries are under greater pressure than we expected. Maybe we should increase our assistance to European countries?" an official participating in the meeting suggested to the public that he did not understand biology, but he could understand the situation.


    After hearing the official''s proposal, everyone discussed it and agreed.


    After all, it was in order for European countries to block alien creatures that Yanguo decided to help Europe. Now it is found that the pressure on the Europeans is greater than expected. Naturally, it is necessary to add some assistance so that they can carry it.


    "Then let the fleet build a field airport, and then provide a batch of aircraft air filters from home to European countries. It seems that their aircraft can''t fly yet. With air filters, they can at least restore their air strike power." after some discussion, an officer summarized the opinions of everyone: "As for other reinforcements, wait until the reinforcements give a further report."

 Chapter 738

    After receiving domestic orders, the fleet naturally took action soon.


    It has become a talent to carve DNA like farming. Infrastructure is naturally a good skill of Yanguo people. A temporary military airport was soon put into construction. With the play of 3D printing equipment, the construction period will not be too long.


    The construction of the airport was progressing smoothly, but diplomats encountered trouble when they asked European countries to provide aircraft intake culvert data for domestic production air filtration.


    "Sir, did I hear you right? You don''t have fighter planes?" the diplomat looked at the embarrassed French staff in front of him and felt a burst of disbelief.


    Although some people milk the law every day, and the iron cross is rusty and rusty, and Da Ying only cares about stirring the foundation and selling corruption, they are all traditional European powers. In those years, they were full of martial ethics. Although the two world wars drained their blood, leading to the decline of old Europe after World War II, it is not that they can''t even take out fighter planes now?


    Although English has lost its hometown and France has lost Paris, you are also an old industrial power at least!


    Even if the plane can''t take off in this environment, the fighter is useless, but why don''t you even have a fighter?


    Diplomats think so and ask so. After all, in this environment, he is not in the mood to play diplomatic rhetoric with each other.


    However, facing the questions of diplomats, the French staff regretted that: "We did have some fighters before, and they were sealed up when the disaster came, but we started them when alien creatures came. However, the harsh environment and the existence of flying units in alien creatures have led to their loss."


    "Haven''t you continued to build new ones?" the diplomats wondered.


    Before the disaster, your countries were unable to afford so many planes because of insufficient military expenditure. It is understandable that you are unwilling to continue to build.


    After all, we couldn''t fight at that time. We just maintained the basic national defense force.


    Moreover, even if Lucia on the other side goes crazy and starts to push Europa, at least old Europe is a member of the North Atlantic Treaty Organization, and now a European Union has been formed. It is not impossible for countries to gather their troops together, so there is not much demand in this regard.


    But it''s a time of war! You''re fighting alien creatures!


    Don''t you make up for the loss of your own fighter? Do you want to lie flat like this! Aliens have air units! Don''t you want to control the air!


    "The air units of alien creatures don''t have strong air control ability, and most of the time they fly at low altitude. We have arranged a large number of anti-aircraft guns on the defense line, which can effectively solve these flight units, so we don''t suffer too much in air control." franxi staff explained to the foreign diplomats, showing a slightly helpless expression: "We also want to build new fighters, but... A fighter needs to consume enough resources to arm our soldiers of a regiment. We can only use our resources where we need them first."


    The high cost of modern fighters is indeed a fact. The price of a gust fighter developed and produced by France is about 70 million euros, and this money is more than enough to provide a full set of individual arms for a regiment of the army, and even complete heavy equipment.


    In today''s environment, European countries need enough troops to fill the front. It is indeed more cost-effective to arm more infantry than to build a fighter.


    Especially in today''s environment, the service life of fighter is greatly shortened, and the engine can''t bear the flying environment of dust explosion.


    Therefore, it is not incomprehensible that European countries do not want the air force at all.


    But understanding is understanding. The diplomats of Yanguo still feel incredible and unacceptable.


    Yanguo is also fighting against alien creatures. Although the strength and scale of the alien creatures it faces are weaker than those in the European battlefield, Yanguo is not as passive as European countries.


    Thinking of this, the diplomats felt proud of the country, but they couldn''t help but say to the French staff: "originally, according to China''s plan, it was intended to assist a number of air filtration equipment used by aircraft to your country, so as to help your air force restore its combat capability and fight against the air units of alien organisms.


    But now that you have no fighters, we can only modify our original plan. I hope your country doesn''t mind. "


    Although I feel helpless and bored, I still have to say what I should say.


    "It should be. Our people are very grateful to your country for its assistance. On behalf of our country, I would like to express my gratitude to your country." the French staff expressed their gratitude to the foreign diplomats and also said to him: "With regard to assistance, in fact, after discussion between China''s top leaders and the military and other countries, we urgently need more exoskeletons and electromagnetic rifles to arm our soldiers and enable them to fight against those alien creatures."


    The diplomats of Yanguo nodded and replied positively: "I will tell you this at home. In fact, our logistics base in Ruhr Industrial Zone has begun to produce these equipment, and the first batch of equipment has been provided to Germany and Italy. I believe you will get what you want soon."


    "That''s better. With the equipment that can kill those alien creatures, our soldiers will be more brave to fight with these alien creatures and resist their invasion." the French staff seem to have great confidence in their soldiers.


    But the diplomats of Yanguo were not as optimistic as him. Although they didn''t say anything on the surface, they had no good impression of these Europeans.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    After returning to the fleet station, the diplomats briefed China on the situation in Europe.


    "These Europeans..." after listening to the report of the diplomats, the domestic officials responsible for contacting the fleet immediately felt helpless.


    Originally, they thought that European countries were more or less not so bad, but who could have thought that the actual situation was that they were worse than they thought?


    "OK, I have understood the situation, and I will report to the relevant departments." the official nodded to the diplomat to understand, and encouraged him: "your work has been completed very well. As for the support plan for Europe, China will redraft the support plan, and you will need your help at that time."


    After saying this, the official seemed to think of something and said to the diplomats: "the cargo ships transporting materials to Europe should arrive in these two days according to their speed of action. You should pay attention to receiving materials and assisting them in their work. They don''t just send materials, but also need your assistance in other tasks."


    "It''s our duty." the diplomat nodded seriously. Although he didn''t know what he needed to help, he agreed without any hesitation.

 Chapter 739

    The news that Europeans no longer have fighter planes really surprised the senior leaders of Yanguo.


    Although everyone expected that ferra in old Europe would be unbearable, they didn''t expect that they could be unbearable to this extent.


    In the face of such a situation, although many people feel that it may be easier for Yanguo to fight aliens by itself, a special meeting was held to discuss a new aid plan for Europe.


    After all, after all, these Europeans are still really resisting the invasion of alien creatures, and it''s not good for Yanguo to really leave it alone or take over it by themselves.


    Perhaps taking over by themselves may give better play to the resistance of these Europeans for Yanguo, but considering the various problems that need to be faced by taking over by themselves, Yanguo''s high-level still gave up this tempting idea after serious consideration.


    In the final analysis, although Yanguo is much better now, there are still many problems to deal with at home, and there is not much margin to deal with European problems.


    It''s true that if you take over completely, you can get a series of benefits such as the territory and population of old Europe. However, it''s a pity that today''s inflammatory country doesn''t have such a big appetite to swallow such a big piece of cake, even if Lucia is an ally.


    "All comrades know about Europe. Do you have any views?" the senior leaders who presided over the meeting asked.


    "These Europeans are going back and forth! Let me just say that we should send troops by ourselves. Anyway, there are land ships now, and sending troops in the past is not a trouble. These Europeans are unreliable!" an officer participating in the meeting directly expressed his dissatisfaction with the Europeans and put forward his own ideas at the same time.


    Soldiers always have a more direct way to solve problems. Since the Europeans are not in charge, we will do it ourselves.


    Although this idea is direct, it can be regarded as an idea. Yanguo also had such consideration at the beginning. It is only affected and dragged down by the domestic battlefield. Now the military does not have enough troops to send to Europe to fight.


    So for this idea, an official said directly: "although land ships can help us transport our generals to Europe, it''s a pity that we don''t have enough troops to maintain two fronts at the same time. It''s too expensive!"


    "Yes, not only the troops can''t keep up, but also the logistics can''t keep up. At present, the ammunition consumption in the Dongting Lake theater is very large, and we can only ensure the consumption of one battlefield." another official immediately opened his mouth and explained the current logistics supply situation.


    The statements of the two officials obviously dispelled the idea that the officers wanted to send troops directly to Europe.


    However, it is obviously impossible to ignore the problems of Europe. For today''s inflammatory countries, they also need European countries to exist, maintain their defense lines and resist the attack of alien creatures, so that the inflammatory countries can focus on dealing with domestic alien creatures.


    "The support to Europe must continue." the senior leaders who presided over the meeting knocked on the table a little and set a tone for the discussion: "the lucians are now building the Eastern European defense line as the second defense line against alien invasion, so they can''t spare too much manpower for the time being.


    According to the information we received from Lucia, they can only send another brigade at most, so we are unlikely to take over the European defense operation ourselves.


    Although everyone doesn''t want this line of defense to be useful, we still want Europeans to continue to stick to it until the construction of the line of defense is completed!


    Moreover, even if the Eastern European defense line is completed, according to the plan of the lucians, it is also to gather refugees and defeated troops from European countries, and then use them as the main force to fill the defense line, so we''d better think about how to make European countries last longer. "


    Since the top leaders have set the tone, others naturally can only discuss around this tone.


    At this time, Chen Xin suddenly asked, "I remember that before the end of the cold war, the North Atlantic Treaty Organization sealed a large number of military equipment in Europe. Don''t you know if these things are still there?"


    "Cold war equipment?" Chen Xin''s question immediately attracted a burst of surprise. Everyone was surprised why Chen Xin asked this.


    However, in this kind of meeting, since someone asked, someone would answer, so soon a staff member replied: "Most of these equipment are still there. Except for a small part of the sealed warehouses that were submerged by rising sea levels or damaged by bad weather, most of the cold war equipment sealed by the North Atlantic Treaty Organization are still there, and it is certain that they can still be used now. In fact, European countries have unsealed a considerable part of the cold war equipment for arming him Our army is gone. "


    Perhaps thinking that Chen Xin''s question might be related to the issues discussed at the meeting, the staff added: "it seems that they still have a batch of sealed cold war fighters, but they have no plan to use them because they lack maintenance parts."


    Hearing this answer, Chen Xin nodded clearly and then said, "I think we can send a maintenance team from home to Europe to help these Europeans repair the sealed aircraft and put it back to use.


    Although these aircraft are all products of the cold war period, they can also be used to fight alien creatures. As for the problem of parts, as long as they are willing to provide drawings, I think it is not a problem to print a batch of parts for them with 3D printing equipment. "


    Chen Xin''s proposal stunned the participants at the meeting, but they soon agreed to his proposal.


    Although the fighters in the cold war period are somewhat backward compared with modern fighters, they are still quite desirable. After all, they want to fight alien creatures, and they do not use the awesome electronic countermeasures and radar stealth functions of modern fighters. Their flight speed can also reach hypersonic speed, which is more than enough to fight alien creatures.


    And more importantly, during the cold war, Europe was the buffer zone between the Federation and Subia. If there was a war, this was the battlefield, so European countries and the Federation deployed heavy troops and a large number of weapons and equipment here.


    At that time, they were preparing for the Third World War at all costs. The number of these weapons and equipment was amazing.


    Even with the disintegration of Subia and the end of the cold war, most of the equipment was eliminated, but there are still an amazing number of these left to be sealed.


    Although these aircraft and weapons and equipment are not in good condition due to the lack of maintenance and repair parts, these old guys can still come in handy as long as they are repaired.

 Chapter 740

    Charlie is a pilot of the Royal English air force. After the disaster, because English gave up its strategy of ensuring national survival, he and his flight group were transferred to an air base in the southwest of France and stationed here.


    They were stationed with a French flight regiment, which made the air base, which was not too large, seem a little crowded and cramped.


    However, this was only temporary. When the alien invasion began, the two flight regiments stationed here and their aircraft were soon exhausted.


    A flight regiment usually has about 24 fighters, 50-80 pilots, a varying number of reserve pilots and about 200 ground service personnel.


    In the modern war mode, the two flight regiments are quite powerful, but in the face of an overwhelming array of alien creatures and harsh weather conditions, the two flight regiments and the fighters they are equipped with can not play their due role. Needless to say, the loss is also relatively fast.


    This also led to a month after the war with alien creatures, in the air force base where Charlie was located, there were only half of the two flight regiments combined with almost 200 pilots, more than 50 fighter planes were lost, and only seven or eight aircraft that were repaired due to engine damage or lack of parts survived.


    Not only that, the ground crew also suffered a certain loss. Although the loss was small, it still depressed the morale of the whole air force base.


    Although the statements of the first class air force, the second class Navy and the third class army are just a joke, this can really reflect the difference between the three from the side. After all, the air force pilots are the most refined and expensive. The navy is also a high-tech arm, and only the army is very ordinary.


    Especially for the English people, the army is the only force in the English armed forces without a royal title.


    In the past, Charlie was very proud of his status as an elite pilot of the Royal Air Force.


    But now, the army, which has always been despised by them, is fighting hard on the front line to withstand the attack of alien creatures, while their air force can only squat in the air base, which not only stimulates their self-esteem, but also undoubtedly exacerbates the low morale of these air force pilots.


    A large number of aircraft losses not only make them unable to fight, but also make them idle now. After all, with such low morale and the loss of aircraft, everyone has no intention to train. Most people just gather in the dormitory to play cards and fight every day to kill boring time.


    If it were not for the current shortage of materials, it would be difficult for even their pilots to buy alcohol. Charlie believed that there would be a lot of drunks in the base.


    Charlie himself is quite self-discipline. Perhaps it is the result of being strictly required by his father since childhood. Charlie still retains the temperament and self-discipline of British gentlemen in those days, and does not degenerate like other teammates.


    But even so, Charlie felt that he could only do this. After all, the whole base is like this now, and he has nothing to do.


    Even the officers at the base were too lazy to restrain these pilots, and even their daily training became indulgent.


    This makes Charlie, who still insists on exercising his physical fitness as much as possible every day and maintaining his state, feel very helpless.


    With a helpless mood, he had a lunch in the canteen. Charlie sat on a table and ate his own lunch.


    Because of the shortage of materials and the need to supply the front line first, the base, which originally had a guaranteed supply of materials, has gradually fallen into a shortage. The lunch has dropped from the original level of bread, sausage and vegetables to the level of almost only potatoes and carrots.


    Even a large part of these potatoes and carrots were planted by the base, which emptied an underground hangar without planes, and then built a greenhouse.


    Charlie doesn''t think he has any complaints about this. He can only eat enough if he can fight. Now there are no planes, and they pilots are useless. It''s nothing to pay worse.


    Just after accepting his life like this, Charlie still felt a little unwilling. He hoped to get a new plane up there. He could also fly the plane back to the battlefield to fight those alien monsters. Only in this way did he feel that he didn''t waste his life.


    In fact, Charlie is already reporting and applying to be transferred to the front line. Even if he only operates machine gun shooting in the trench, Charlie thinks it''s better to stay in the base and do nothing.


    However, it is obvious that Charlie''s superiors do not want to send valuable pilots to waste in the trenches ahead. Even if they have nothing to do now and have no new aircraft for them, they are still valuable pilots and can''t waste so much.


    While Charlie was eating potatoes and thinking about how to persuade his superiors to transfer him to the front line, a pilot with a French logo rushed towards him and shouted, "Hey! Charlie! Good news! We have a new plane!"


    "New plane? What new plane?" Charlie didn''t understand the situation. He quickly grabbed the French pilot and asked him, "Renault, make it clear, what''s going on?"


    Renault, who was held by Charlie, was very excited and danced to Charlie to vent his emotions: "new fighter! Charlie! New fighter! 20 sea harriers sealed during the cold war and 18 phantom F1! We have a plane! We can fly again!"


    The French pilot Renault is a friend whom Charlie met after he came to the base. He is usually very enthusiastic. Obviously, it is very exciting for him to have a plane to fly again.


    However, Charlie was surprised and puzzled at the same time. He wanted Renault to ask, "harrier and phantom F1? Cold war aircraft? Where did they turn out these antiques? And these antiques have been discontinued for many years? Now there are maintenance parts?"


    These cold war aircraft belong to the outdated third-generation aircraft. Compared with the mainstream fourth-generation aircraft, and even the fifth generation aircraft in Yanguo, Lucia and the Federation, they are undoubtedly backward and will be eliminated.


    However, this does not mean that these aircraft can not be used. After all, they are also the main models in those years. Many aircraft that served only at the end of the cold war have been sealed up for only more than 20 years, and they are still enough to fight alien creatures.


    Even in a sense, these third-generation machines are better than the fourth generation machines to fight alien creatures.

 Chapter 741

    Charlie and Renault left the canteen and went outside.


    The biting cold wind blows. If they don''t wear thick enough and have just had lunch, they are still warm. At this temperature, a person can be frozen through in more than ten minutes.


    However, at this time, both of them did not care much about the cold ice and snow, because the falling things really shocked them, making the two pilots who thought they were well-informed fall into a shameful look of growing up and dumbfounded.


    "This... What is this?" Charlie asked Renault blankly. "Didn''t you agree to have a plane? How did you get a spaceship?"


    "I don''t know... I just heard it said that Yanguo people would help send a batch of planes sealed up during the cold war, but it didn''t say that they would use spaceships to transport them." Renault also looked dull at this time. Although he knew that a new plane would come, he didn''t think it would be in this way.


    In their unbelievable eyes, the huge cargo land ship landed on the apron of the base.


    Naturally, the officers of the base were also deeply shocked, but they at least remembered what they should do, so they greeted them with their prepared ground service.


    However, standing under the huge cargo land ship and looking up at the huge steel creation with a height of more than ten floors, they still couldn''t believe it.


    Although before the disaster, Yanguo''s strong industrial strength and infrastructure capacity had shocked the whole world, and the officials of various countries had been promoting the threat theory of Yanguo, when Yanguo really didn''t know where to take out this terrible big guy in front of them, they still had a loss of what to do.


    I''m just talking. Why did you really make this kind of thing?


    In fact, the European countries were also in an uproar and shocked at the fleet composed of all land-based ships sent by the Yanguo people. However, while shocked, the countries could not help but rejoice secretly.


    At this time, the stronger the inflammatory country is, the more good news it is for all countries. After all, they are about to be unable to carry it. The arrival of the reinforcement of the inflammatory country gives them the possibility to continue.


    Just like now, for Charlie and Renault, although the cargo land ships of Yanguo people are shocking, they are not comparable to the dozens of fighter planes unloaded from the belly of this large ship.


    Because the spaceship is owned by others, the fighter plane is its own. Although these dusty fighters are old, after maintenance, these veterans can carry them back to the battlefield instead of rotting in the base.


    However, Charlie was still amazed by the huge cargo land ship in front of him. He couldn''t help thinking how powerful it would be on the battlefield if the huge ship had enough firepower.


    Charlie just thought like this, but Renault on one side asked Charlie with a very exaggerated look: "Charlie, why don''t these Chinese people put guns and missiles on this ship and use it to fight alien creatures? It''s no better than those old cold war fighters?"


    As ordinary pilots, Renault and Charlie have not been in contact with the outside world for a long time. Naturally, they don''t know that the Yanguo people sent not only the freight land ship in front of them, but also the real warship and aircraft carrier.


    "They have, not only warships equipped with missiles and artillery, but also an aircraft carrier that can fly in the sky." a French officer who followed the cargo land carrier to deliver goods seemed to hear Renault''s words, came up to them and asked them, "are you pilots?"


    Renault and Charlie looked at the rank mark on the officer''s collar and quickly stood at attention and saluted: "yes, sir, we are pilots."


    The officer nodded slightly, looked at their fairly good mental outlook and nodded with satisfaction: "come on, boys, you actually did a good job. Although we lost a lot, in the face of those alien monsters, losses and sacrifices are inevitable.


    With these planes, you guys can go back to the sky again! Although it''s just some old planes, I don''t think you mind? "


    "Don''t mind, sir!" Charlie and Renault responded to the officer, but after answering, Charlie asked the officer, "Sir, can I ask a question?"


    "What''s the problem?" the officer seemed in a good mood and motioned Charlie to make himself at home.


    Charlie organized the language and looked at the cargo land carrier unloading and the cold war fighter it unloaded. He couldn''t help asking the officer in doubt: "Sir, these old aircraft can really be used again, but there is a big gap compared with the ships of the Chinese people, isn''t it?


    Why not let the Yanguo people use their spaceships to fight alien monsters? Compared with the Yanguo people''s spaceships, these old-fashioned fighters are like the products of the last century... No, they are the products of the last century! "


    When Renault saw Charlie say this, he couldn''t help but say, "yes, sir! You just said that the Yanguo people not only have spaceships equipped with artillery and missiles, but also built a flying aircraft carrier. It''s good for the Yanguo people to use their spaceships to fight alien creatures. What do you want us to do with these old-fashioned planes?"


    "Don''t you think we don''t want to?" the officer shook his head helplessly when he heard the words of the two pilots: "the people of Yanguo sent a whole fleet, including aircraft carriers, warships and the large cargo ships you see now to transport materials. Of course, we want them to go to the front line to fight alien monsters, but they refused."


    Charlie and Renault were puzzled when they heard the officer''s answer: "why? The invasion of alien monsters is a matter for all mankind! Why don''t Yanguo people help?"


    "Because their fleet plays a more important role! And there are alien creatures invading in their country." the officer looked at the two people. Although he felt that the Yanguo people should send their fleet to the battlefield out of some prejudice, he explained to them: "Now the Yanguo people are using their flying aircraft carrier to produce powerful equipment for our front line, so we can''t let them pull the fleet to the front line to do those alien monsters, so we need you guys to drive these old Cold War aircraft to fight those alien monsters."


    Charlie and Renault looked at each other and saw the same expression in each other''s eyes.


    Charlie couldn''t help asking the officer, "excuse me, sir, can we ask what equipment the Yanguo people are producing? I don''t think any equipment can be stronger than flying warships."


    When Charlie asked this question, a team of soldiers in exoskeleton protective clothing were coming down from the cargo land ship with electromagnetic rifles.


    "Practical exoskeletons and electromagnetic rifles are better for Yanguo people." the officer looked at the team of soldiers with envy in his eyes.


    Charlie and Renault felt that they had been shocked enough today. It was like that during their stay in the base, the world had become unknown to them, which made them sigh: "what are our scientists doing?"


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 742

    "What are our scientists doing?" not only Charlie and Renault have such questions, but also the executives of France, England and Germany have such questions.


    After seeing the fleet named land line but actually flying out of the pockets of Yanguo people, as well as the exoskeletons and electromagnetic rifles that have now been equipped to the army, the Titans and power armor that Yanguo people are using, and the 3D printing technology they use to build the base


    All these, one by one, have made European leaders wonder at the shocking science and technology in China. At the same time, they want to grasp their scientists'' necks and ask them what they do with so much R & D funds every year.


    Why are the floating warships of the Yanguo people in heaven? They can''t even make a practical exoskeleton.


    "I think we should urge those scientists. They have obtained the samples of Yanguo people''s exoskeleton and electromagnetic rifle at the first time, but so far, they don''t say that they have built our own exoskeleton and electromagnetic rifle, and they haven''t even done the technology to crack Yanguo people, which has to make people think about what they are doing." the Frenchman expressed his opinion, And don''t forget to emphasize: "we allocate so much research funds to them every year, even in today''s environment, we still guarantee their material supply and all needs. I think it''s necessary for us to consider whether this money is worth it."


    It is understandable that French people feel that the investment in scientific research departments is not worth it.


    Before the disaster, European countries were at the same level as Yanguo in terms of scientific research level. Although it is obvious that Yanguo has come to catch up with Yanguo in recent years, the declining old European rotten ship also has three Jin nails, so it is unlikely to say that the gap is too large.


    But now, the Yanguo people are land-based ships and power armor, but the scientists in old Europe can''t even crack the exoskeleton and electromagnetic rifle with ready-made samples, which really makes the leaders of European countries angry.


    Even if the disaster caused by the meteorite fall sets back the scientific and technological level of various countries, it is not enough to say that there is such a big gap between Europe and Japan?


    "I don''t think it''s scientists'' fault, but Yanguo''s science and technology has really lagged behind us." the English people didn''t care so much about it. They took off their glasses and wiped them. Then they said, "I''m more concerned about when Yanguo people can provide us with relevant technology, even if it''s just the foreign trade version they provide to us."


    For the English people who have lost their homeland, it is not important whether they can develop their own research and development. As long as they can get the technology for production, they can be equipped to the army to resist aliens.


    "I''m afraid this is not enough for the time being. The people of Yanguo have offered some trading conditions, and we need to discuss whether to answer..." the German people on one side explained, but they didn''t seem to want to agree to the conditions of Yanguo people.


    But before he had finished, the Frenchman had patted the table and said: "Promise them! Promise them whatever conditions! What we need now is more exoskeletons! More electromagnetic rifles! Their power armor and the humanoid mechanical armor called Titan! With those, we can fight against those alien monsters instead of filling the front with the lives of soldiers!"


    "But many of the things that the Chinese people want are within the scope of the embargo of the Wassenaar agreement, and we need to discuss..." the Germans still want to explain, but obviously these are just excuses.


    In fact, the aid provided by the Chinese people is not much that the Germans want to accept.


    Although they agreed to lend Ruhr Industrial Zone to the fleet of Yanguo, and provide them with resources to produce equipment for the front line, in the view of the Germans, it is enough to do so.


    England and France on the front line, as well as other countries, rely on German blood transfusion to resist the attack of alien creatures. The help of the Chinese people is only icing on the cake. In fact, it is the best situation for the Germans to maintain the war situation in this way.


    In a large-scale war, the former enemies are constantly bleeding, but they do not directly participate in the war, but only supply materials to other countries to earn benefits. What is better than this?


    In World War I and World War II, the Federation was in such a position. As a participating country, it did not directly participate in the war, but more provided materials, which is why the Federation became the world''s first power after World War II.


    Now, it''s finally Germany''s turn to do so!


    However, this is unacceptable for English and France, as well as other countries.


    The Italian patted the table directly and said with great dissatisfaction: "if the front-line Italian army can''t get enough exoskeletons, electromagnetic rifles and other weapons that can effectively kill those alien animals, then the Italian army will no longer resist the attack of those alien animals and give way to the defense line that the Italian army is holding!"


    Behind the Italian defense line is Germany. Once they get out of the defense line, alien creatures will drive straight into Germany.


    "No, you can''t..." when the Germans heard the threat from the Italians, they immediately felt a little flustered. How can the Italians get out of the defense? Are their pig teammates crazy?


    However, other delegates at the meeting expressed their support for the Italian statement.


    "If Italy gives way to the front line, as long as it does not give way to the Swiss line, you can withdraw to Switzerland," the Swiss expressed his attitude.


    "If the Italian army leaves the line of defense, the Austrian army will choose to retreat because it is unable to stop the attack of alien creatures." the Austrian also chose to stab the Germans at this time.


    Germany faces the Mediterranean, next to Switzerland and Austria, and in front of them is Italy. If these three countries open their defense lines, the Germans will face the front of alien creatures directly from the Mediterranean.


    The Englishman on one side put on his glasses again and said in a calm but oppressive tone: "maybe you have your own plans, but no matter what your calculations, we need all the help that can help us win the war! No matter what the price of this help needs to be exchanged!


    One thing you need to make clear is that this war is not a civil war between humans. You can survive by surrender. This is a life and death struggle between humans and alien creatures. If we lose, it doesn''t matter Germany, England and France! The whole mankind will perish! "

 Chapter 743

    No matter how many little abacus the Germans have, they still choose to compromise and be soft in the face of the common pressure of other countries.


    After all, today''s Germany is no longer the German one, two or three empire in those days. Regardless of whether the military morality is abundant, the whole country has become very short-sighted in a sense and only pays attention to the immediate interests.


    Otherwise, they will not make the move that the front is still in war and the rear begins to drag their feet for interests, especially if it is still a war of subjugation and extinction.


    However, under the pressure of various countries, especially the move of Italy, Switzerland and Austria threatening to release the positive defense line, Germany finally had to agree to exchange its consent to the people''s request for more assistance.


    What is demanded by Yanguo is mainly the lifting of the ban on nine categories of embargoed materials originally included in the Wassenaar agreement, such as special materials and related equipment, navigation and avionics equipment, computer equipment and so on, which have been embargoed by European countries before the disaster.


    Originally, some radical people in China intended to directly ask European countries to abolish the agreement, but after some discussion, they were still slightly less aggressive, just asking for the lifting of some embargoed materials.


    The main reason is that Chen Xin has helped to open and hang up in China. Many things that could not be imported have been better replaced. Only some things that are not so urgently needed or there are no relevant supporting industries in China still need European technology.


    Before, Li Yulong and his white gloves actually did the work of collecting these materials and technologies in Europe.


    With the materials allocated to them, they find these factories with the production technology of materials on the embargo list, or directly exchange technology and equipment, or sign long-term production orders, in order to get these materials and related technologies back to China.


    Now that European countries have agreed to the conditions of the United States, these materials and technologies originally on the embargo list can be collected and transported back to China more easily.


    In addition, with the conditions of European countries agreeing to Yanguo, some cutting-edge technologies originally held in the hands of various countries have also been obtained by Yanguo.


    Accordingly, China naturally began to provide more assistance to European countries.


    A number of foreign trade versions of power armor and heavy machine armor were loaded and shipped to Europe by the second cargo land ship, while the first cargo land ship loaded with goods also set sail from Europe and returned to China.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "It seems that they have done a good job in Europe!" on the land cargo ship arriving at home, the official who came to receive materials looked at the list of materials returned with the ship, and his face was filled with joy.


    If he could get such a ship of materials and technologies before the disaster, he would be crazy. Many of them are key technologies and products of the embargo imposed by European countries on inflammatory countries for decades, and many of them affect and restrict the development of inflammatory countries in relevant fields to a considerable extent.


    This forced Yanguo to start from scratch and go through the road of European countries again bit by bit, so as to catch up with the level of European countries.


    Although this makes Yanguo walk out of its own road and will no longer be restricted by anyone, the wasted time and resources, as well as the energy invested by those scientific researchers and their precious youth can not be exchanged for anything.


    However, now, with the efforts of domestic scientific researchers and comrades on other fronts, Yanguo has finally become strong. European countries have to take out these things originally embargoed in exchange for Yanguo''s assistance.


    In the official''s view, this is undoubtedly a great victory and success. At the same time, it is also the best irony to European countries.


    Thinking of this, the official especially wanted to thank Chen Xin.


    In his opinion, Chen Xin has made great contributions to the country''s ability to feed and warm the people in the face of such major disasters, and even spare no effort to support Europe.


    Not to mention anything else, isn''t this land cargo ship used to transport goods between Europe and China built by Chen Xin?


    Although he is not an expert in science and technology, he also knows that the anti gravity technology used by Chen Xin on this land ship is stunned by researchers in related fields.


    This is really the anti gravity technology that only appeared in science fiction. So far, what humans can achieve is only superconducting magnetic levitation in the laboratory, which is thousands of miles away from this anti gravity technology.


    The shock brought by this incredible technology even makes people wonder if Chen Xin is an alien.


    After all, the sudden leap in science and technology can also be described as a burst of inspiration, but for Chen Xin, I''m afraid no one will think he is a burst of inspiration genius.


    Because he has produced too many achievements. If this is a burst of inspiration, his inspiration is the flood discharge of the Three Gorges dam.


    Moreover, his fields are too extensive, covering almost all industries and fields he can involve, and can make achievements that ordinary people can''t match.


    This is obviously not a normal situation. After all, if this is a normal situation, everyone will have to hang. It''s too far worse than Chen Xin.


    Apart from other things, is it just an exoskeleton that the military didn''t study at the beginning? However, the shackles of energy and operating system have seriously limited the development of the military in this field. Until Chen Xin came up with a mature exoskeleton scheme, this easy-to-use and convenient equipment can be equipped with the whole army and applied to the civil field.


    There are many examples like this, so that even the most dull and stubborn conservatives know that what happened to Chen Xin can not be explained by the acquired scholar syndrome.


    There must be a deeper secret in him.


    But even those who have ideas have no intention to explore what secrets Chen Xin has.


    Because Chen Xin has made too many contributions to the country.


    For the whole country, as long as Chen Xin has not done anything harmful to the country, can''t such a big inflammatory country accommodate a person with a little secret?


    Especially when Chen Xin is still making unmatched contributions to the country with his hidden secrets, the senior management can say to those who have ideas: "if you want to dig Chen Xin''s secrets, you can replace his contributions to the country first."


    To paraphrase the famous saying of the chief designer, whether white or black, a good cat is one that can catch mice.


    And even if Chen Xin stops making new contributions to the country, with his contributions now, the country will not have any adverse thoughts on him.

 Chapter 744

    A large number of materials and technologies from Europe have naturally spread to Chen Xin.


    But he didn''t care much about it.


    On the one hand, it will take a long time for China to digest these technologies. On the other hand, the military is planning a counter offensive in order to eliminate alien creatures in the Dongting Lake area.


    A huge problem for the counter offensive is how to go deep underground and deal with alien creatures who can climb to the ceiling in the tunnel.


    For humans, the huge physical gap makes it difficult for humans to fight against alien creatures in a narrow place, especially after losing the support of quantitative advantage and heavy firepower, the combat power gap between humans and alien creatures can be said to be like an ordinary person trying to knock down a cow with his bare hands.


    Moreover, after entering the underground tunnel, ammunition supply, logistics support and other aspects need to be considered.


    In order to counter attack the plan, the military is gathering its elite troops, planning to arm them with heavy machine armor, and then cooperate with the Titan forces to clear the underground alien creatures, just as Chen Xin and them went deep into the alien nest last time.


    But even so, the military wants to get more powerful weapons.


    Besides, at least there should be heavy armored units that can provide cover and fire support for ordinary infantry, which can not only resist the attack of alien creatures, but also effectively output fire as a fire platform.


    This is not a good goal to achieve.


    Although Titans can be equipped with shields as heavy armored units, they can not be regarded as heavy firepower units due to the design problems of Titans themselves.


    Although portable short barrel guns and heavy machine guns can play a good lethality, there is still a certain gap between them and the heavy firepower expected by the military.


    After all, due to the Titan''s own design, the amount of ammunition they carry is limited. Conventional battlefield operations are good, logistics can keep up, and there is no problem as long as ammunition is available.


    The modular ammunition boxes designed by Chen Xin can ensure that they can change ammunition in a very short time even when there is the most intense exchange of fire on the battlefield, and will not affect the operation.


    However, in the narrow, rugged and deep underground tunnel, it is very difficult to ensure the supply of ammunition.


    Therefore, what the military needs is a combat unit that can be used in the underground tunnel environment and can stably and continuously give full play to its firepower advantage.


    And this is just not a good requirement to meet.


    According to the experience gained in the battlefield today, the intensity of fighting with alien creatures has even exceeded that in the battlefield of World War II. Heavy machine guns are often fired directly with one bullet chain, then change the second one within half a minute, and then continue to buckle until the barrel is red.


    In today''s environment where the temperature is tens of degrees below zero, it can be imagined how many bullets need to be thrown if the barrel of a heavy machine gun can be turned red.


    If it were not for the fear of insufficient firepower in Yanguo, which has led to a large number of ammunition in China, I am afraid I would still worry about this huge consumption of ammunition.


    Now it''s good. The ammunition that has been overstocked for many years and is about to expire has been hit out, which has greatly reduced the storage pressure of logistics.


    However, to plan a counter offensive, how to ensure ammunition consumption is a very serious problem.


    If this problem is not solved, it is obvious that the military has no way to realize their plan to counter attack and clear up alien creatures.


    To solve this problem, the military''s first thought is naturally Chen Xin.


    In the military''s view, Chen Xin is about to become a Doraemon existence. If you have any needs, you can basically solve them by opening your mouth.


    Especially after the land fleet came out, Chen Xin already felt that he was omnipotent within the military. At present, the military is arranging people to reassess some ideas and plans that could not be realized because of his big brain. It is expected to take out some of them that can be realized and show them to Chen Xin to see if they can be realized.


    Of course, the military only has this idea about those plans with big brain holes, and has not really taken them out.


    At present, the first thing to be solved is how to ensure ammunition supply and fire support in the underground environment.


    Firepower support is not too difficult to solve. An excellent self-propelled artillery platform is enough to solve the problem. The only trouble may be the traveling chassis.


    After all, Chen Xin''s next tunnel dug by alien creatures is rugged and winding. The tracked chassis of tanks and self-propelled guns and the wheeled chassis of armored vehicles used by the military are obviously unable to adapt to the passage in this environment.


    However, this point is easy to solve. When Chen Xin first developed the mining Titan for mining, he once made a multi legged chassis imitating the spider ecological structure, which was originally used in the mine. It is very suitable to be transformed and used as the chassis of the fire platform.


    As for the firepower platform itself, it can be modified with the military''s ready-made vehicle turret.


    This kind of work can even be completed by ordinary weapon designers without labor. Chen Xin does it himself.


    The problem of vehicle chassis is solved, and the problem of ammunition supply can also be solved. It''s OK to change this chassis into a carrier platform.


    In fact, when receiving the military''s request, Chen Xin already had a lot of ideas. He even conceived many models of different sizes.


    Small robots can be made into spiders, carrying one or two ammunition boxes. They are specially responsible for transporting ammunition for front-line combat forces. They can go out in groups or perform tasks alone.


    The larger one can be the size of a cart. It is also a robot, and this spider robot can have different functions. It can not only carry ammunition, but also carry heavy machine guns as a fire support platform.


    Larger ones can be made into the size of cars. This one needs someone to drive. Similar to the spider Titan conceived by Chen Xin before, it can not only carry a large number of weapons and ammunition, but also be directly used as a heavy firepower platform.


    The design of three types of vehicles, large, medium and small, can be said to perfectly meet the needs of the military. Even medium and small robots can be used in other environments, and do not need to be limited to the underground environment.


    This also makes the military want to list the two robots in the whole army when they see the design of the two robots.


    After all, with the popularity of all kinds of black science and technology equipment pulled out by Chen Xin, the military''s requirements for logistics supply have become different from before. Although individual soldiers can carry more and more weapons and ammunition by relying on exoskeleton and power armor, the amount of supply has also become larger and larger.


    This has led the military to be very optimistic about this small and medium-sized transport robot that can send ammunition to the front line by itself.

 Chapter 745

    The production of the new robot did not take much effort. Chen Xin just transformed the chassis of the spider Titan he had made, and the chassis of the new robot will be available when the proportion is reduced and some details are adjusted.


    The design of the small robot is very simple. When Chen Xin first built the spider Titan, it was for mining. Therefore, a mine cabin was designed in the belly of the spider. Now it is a ready-made ammunition cabin.


    Just improve the structure and make a card slot, you can directly clamp the ammunition box on it and fix it. No matter how the small robot climbs and rolls up and down, there will be no risk of ammunition falling.


    As for its power source, it is even simpler. Two high-performance batteries are enough for the little guy to carry a box of ammunition and run at the speed of 60kmh for 18 hours in the complex and changeable environment on the battlefield.


    This small robot, which is about the size of a dog, small, agile and flexible, can be said to be the best transporter on the battlefield.


    They can deliver ammunition to soldiers on the front line in time, but they are difficult to be found and attacked. Even on the battlefield of World War II, they are competent to deliver ammunition or other supplies to the front line.


    The intelligent program of the small robot was handed over to the research team that had been studying artificial intelligence before. They wrote a new program with the artificial intelligence program copied from Chen Xin and installed it on the small robot.


    This program allows it to identify battlefield information and terrain, and has a certain logical judgment ability. It can independently judge the situation faced, make judgments, and better perform tasks.


    However, because the tasks that small robots need to perform are not complex, this program is not an artificial intelligence program, but something similar to the previous UAV or auto driving program. Although it is more advanced and intelligent, it is not artificial intelligence.


    On the medium-sized robot, because of the existence of fire support model, it has written a real artificial intelligence program, so that it has a certain logical thinking ability, can judge the situation of the battlefield by itself, and use the four mounted 25mm machine gun to provide fire support for the soldiers.


    The plan of the large spider Titan was rejected by the military. It''s not that this Titan is bad, but that the military feels that this coincides with the functions of the two existing models of Titan, and there is no significant qualitative improvement in performance, so it doesn''t intend to increase investment.


    Chen Xin has no opinion about this. The spider Titan itself is not as practical as the general Titan, and the cost is even higher, which is lost to the Gongshi Titan.


    In addition to its unique structure and huge body shape, in addition to having a certain place to play in underground tunnels, large robots of this shape can not be used in conventional operations.


    However, the fact that the state is considering providing more support to Europe recently has inspired Chen Xin. He plans to modify the design of this spider Titan and throw it to the Europeans.


    After all, there are many mountains in Europe. If spider Titans fight in mountains, the effect should be very good.


    Chen Xin believes that Europeans will like this kind of good thing very much. As for Yanguo himself, it''s better to use cheap Gongshi type.


    As for the cost of a spider Titan is equivalent to two and a half Gongshi. In terms of combat effectiveness, two spider Titans can only beat three Gongshi Titans. There is no need to tell Europeans.


    In this regard, the senior management and the military have no opinion. It is good for the country to take the design scheme that has been verified in China and is not very practical to find Europeans in exchange for more interests.


    Moreover, giving the European spider Titans does not mean giving them all the relevant technologies. The core components are still controlled by Yanguo, but only giving them design drawings and the design of some external mechanical structures and parts.


    After finalizing the plan, production naturally goes fast.


    With the 3D printing equipment provided by Chen Xin, the production of similar technical verification or experimental models has become very convenient. From the original need to find a special person to customize, it can be produced quickly only by drawings, which greatly facilitates the production and research work in related fields.


    However, for the production of medium and small spider robots, the military does not intend to directly equip them to the army, but plans to carry out actual combat inspection first.


    In addition to some of the prototypes produced have been sent to the front-line forces for actual combat testing, the military also plans to send some spider robots to the European battlefield to test whether the performance of this robot can meet the needs of the battlefield with higher intensity combat.


    This idea of the military immediately aroused Chen Xin''s interest. Therefore, he even planned to personally visit Europe to learn about the use of spider robots and other equipment supporting Europe on the European battlefield.


    Naturally, the military and senior management dare not let Chen Xin go to Europe to take risks, which is no better than when he went to Lucia. Europe is a war zone. If Chen Xin encounters any danger, it will be a huge loss to the country.


    However, for this point, Chen Xin said that there is not much distance between his place and the theater in China, and he will only stay at the base where the fleet is stationed to debug various equipment to aid Europe.


    In order to persuade the senior management to agree with him to go to Europe, Chen Xin also said that his visit to Europe can effectively improve the production and living conditions of the fleet station, improve the efficiency and speed of the built base to produce European aid equipment, and produce more equipment to better support the European battlefield.


    Moreover, Chen Xin also said that he needs to know more about alien creatures in order to study new equipment for these alien creatures so that humans can better eliminate them.


    After all, even if the extermination of alien creatures is completed in China, the alien creatures on the European battlefield still have to be dealt with and faced. It is impossible for Europeans to deal with them by themselves.


    After careful consideration, the senior management finally agreed to Chen Xin''s application to Europe. However, they also put forward conditions that they would send someone to follow Chen Xin to ensure his safety. At the same time, they also limited his scope of activities to the station of the European Fleet.


    In addition, Chen Xin''s trip to Europe is not a cargo land ship, but a land frigate allocated by the military.


    In addition, the military also transferred the Titan team fully equipped with special aircraft back as Chen Xin''s personal guard to protect his safety.


    Such treatment made Chen Xin feel flattered, but it strengthened Chen Xin''s idea of testing all kinds of new equipment in the European battlefield.

    This is still Chen Xinran. In the face of Chen Xin''s remarks, the political work cadre just looked at Chen Xin with a smile and was not moved by him.


    "OK, OK, I know. I''ll stay on the ship and won''t run around, but I remember this should be an important grain producing area in Lucia. Please ask me if there is any local food when replenishing. I was impressed by the sausage they provided in their capital before. I like it very much. If you can get it, please help me." In the face of political cadres with this attitude of oil and salt, Chen Xin can only show obedience and jokingly put forward a small request.


    For Chen Xin''s request, the political cadres seriously nodded, wrote it down, and replied to Chen Xin, "please rest assured, I will ask Lucia about it."


    "OK, that''s troublesome. I''ll go back first." seeing that the political cadre promised, Chen Xin had nothing else to do, so he turned and walked towards his cabin.


    Although he enjoyed good treatment on the frigate, Chen Xin''s cabin was just a small cabin no different from other cabins, except that four or six people lived in other cabins. His cabin had only two beds, and he lived alone.


    He took off his coat and hung it on the hook on the wall. Chen Xin washed his face in front of the washstand in the cabin. Then he lay down in bed and planned to have a rest.


    This trip was much harder than the last time he went to the capital of Lucia. After all, he had a special train at that time and enjoyed much better treatment than now. Even the air bag ark was better than the warship in terms of comfort.


    After all, civilian vehicles pay more attention to comfort, while military vehicles pay more attention to combat performance.


    But this is nothing for Chen xinlai. After all, he went to Europe to do business, not on vacation.

 Chapter 747

    Chen Xin''s short stay in Stalingrad did not delay their trip. After replenishment, the frigate set off again for Europe.


    However, after the land ship took off, Chen Xin left the cabin and came to the deck to overlook the city that has left a great reputation in the history of World War II.


    In the war that can be called human catastrophe, suvia and Germany launched a fierce war around the city. Both sides invested heavily here and killed more than 2 million people. It can be called the most bloody and tragic war in modern history.


    Now, however, looking down from the sky, it is difficult to find the traces left by the war.


    On the contrary, the city has long been rebuilt, and now it has become an important logistics node for Lucia to deliver supplies to the Eastern European defense line under construction. The whole city is very lively.


    Stalingrad itself is an important major grain, coal and fuel producing area in Lucia. In those years, the Germans attacked here just to get rich resources in the south of Lucia.


    Now, these valuable resources are transported here and then transported to the Eastern European defense line to support the construction of the defense line.


    Looking at this scene, Chen Xin asked the officer who had been following him: "how is the construction progress of the Eastern European defense line? Do you think this defense line will be used?"


    "At present, the main construction of the Eastern European defense line has been completed by 60%, and the fortresses of several important defense nodes are under construction, but I only hope this is a Maginot defense line." facing Chen Xin''s question, the officer answered somewhat unexpectedly.


    Hearing the officer mention the famous French defense line in the world military history, although Chen Xin could understand his meaning, he still asked, "why do you say that?"


    "Isn''t a defense line that costs a lot of resources and energy to build but is not used exactly in line with the meaning of the existence of the Eastern European defense line?" for the Eastern European defense line, the officers naturally think that it will never be used: "Although we all know the necessity of building the Eastern European defense line, if this defense line is really used, it means that the whole Europe has been occupied. I''m afraid this is not the result you want, academician Chen?"


    Maginot line, a line of defense built by France to resist possible German attacks in World War II, is to prevent the tragic war as in World War I and the tragedy of being hit under the capital city.


    However, the Germans did not attack the defense line directly, but bypassed the forest on the side of the defense line, which made the defense line built by the French spend a lot of time and energy into a decoration, and with lightning speed, the French signed the surrender letter in more than a month.


    The officer mentioned this line of defense at this time, of course, hoping that the Eastern European line of defense would be as useless as the Maginot line.


    After all, if this line of defense comes into use, it means that France, Italy, Austria and other countries on the front line are all defeated by alien creatures, and even Germany has fallen. Otherwise, the military peak of alien creatures can''t reach here.


    However, Chen Xin had another worry. He asked the officer, "what''s the situation in the black sea? Have those alien creatures broken through the Turkish Strait?"


    Although the Eastern European defense line can block the attack of alien creatures from the land, if they break through the Turkish Strait and attack from the Black Sea, they can bypass the Eastern European defense line and then directly insert into the Asian continent, making the whole Eastern European defense line like the magino defense line. It is really a decoration.


    "At present, the situation is still ideal. Turkey is not the main attack direction of alien creatures. Although the attack is also fierce, they have blocked alien creatures out of the Black Sea because of the firm resistance of several countries in the Balkans." when the officer mentioned this matter, he could not help paying a little respect to those countries: "At present, Lucia is trying to provide support for them, and extends the Eastern European defense line to the Turkish Strait, which has been included in the planning scope of the defense line. At present, this is also the only belligerent zone on the whole Eastern European defense line."


    Hearing what the officer said, Chen Xin couldn''t help picking his eyebrows.


    As the birthplace of World War I, the Balkan Peninsula has always been called the Balkan powder keg. Ethnic and religious issues have kept the region in a state of war for a long time. They fight by themselves and foreign interference forces


    There was little peace in this land. Even at the end of the last century, the embassy established by Yanguo here was bombed


    Although more than 20 years have passed, many people have gradually forgotten this history, as a person born in that era, Chen Xin has personally experienced those things. Even in those years, he was a member who took to the streets to protest.


    Now, however, the Federation that caused the embassy bombing has been destroyed under the natural disaster, and the countries of the North Atlantic Treaty Organization are also friendly forces that need support and unity.


    Thinking of this, Chen Xin only feels an unspeakable irony, but this is the necessity caused by the current situation. People can''t help feeling that if there are so-called gods and controlling the damn fate, he must be a hopeless bastard.


    However, despite such thinking, Chen Xin did not intend to retaliate against European countries or pit them. After all, these countries are also comrades in arms of the same camp to resist alien invasion. Pit them led to their defeat, the collapse of European defense lines, and the long drive of alien creatures is obviously not the result Chen Xin wants.


    But if you don''t pit them, it doesn''t mean you can''t let them suffer or shed some blood. After all, Yanguo''s assistance is not free. Since they want all kinds of materials and equipment supported by Yanguo, it''s serious to exchange the price and interests satisfactory to Yanguo, isn''t it?


    As for free aid... If Yanguo dares to give it to them, it may not dare to ask for it. The most expensive thing in the world is free.


    Thinking about these problems, Chen Xin was still worried about the Turkish Strait, so he asked the officer, "can we go to the Turkish Strait when we return? I want to know about the defense construction there. After all, if the Turkish Strait is broken through, all our efforts will be in vain."


    "I see. I''ll apply to China. If we get the permission from China, we can go there." the officer nodded and didn''t refuse. Although he needs to prevent Chen Xin from running around to ensure his safety, he doesn''t mean that Chen Xin is not allowed to go anywhere.

 Chapter 748

    The land frigate did not land in the whole journey, but went all the way west, crossed the European part of Lucia, entered Eastern Europe, and then directly crossed the land of Germany to reach the fleet base stationed in Ruhr region in western Germany.


    Because it did not intend to land, supplies were also replenished in Stalingrad. In addition, the whole Europe was not big, so the land frigate went very fast.


    Yesterday they were still resupplying in Stalingrad, and today they are about to fly over the Eastern European defense line.


    "Academician Chen, did you get up so early today?" in the bridge, the captain was sitting on the bench directing the ship''s progress. Seeing Chen Xin walking into the bridge, he quickly greeted him warmly.


    It is the morning now. Although there is no sunshine in Europe, everyone is still working in strict accordance with the specified work and rest time on the warship.


    However, Chen Xin is not a crew member on the ship. He does not need to abide by the work and rest time of the army. Therefore, the captain was surprised that he arrived at the bridge so early.


    "The soldiers got up too early. I couldn''t sleep when I heard the sound, so I got up together." Chen Xin smiled and explained a little. Then he came to the porthole and looked out of the porthole.


    Because it is only cruising, the flying altitude of the land frigate is not high. Even if you look out from the porthole of the bridge, you can see the ground.


    Originally, Chen Xin thought it would be dark outside, but to his surprise, the ground below was brightly lit, illuminating the whole land, and a large number of workers and construction machinery were working.


    Chen Xin was stunned, but quickly reacted and asked the captain, "are we over the Eastern European defense line now?"


    "Yes, the following is the Eastern European defense line under construction. Now this section we see should be the Polish defense line." the captain glanced at the navigation map and explained to Chen Xin.


    Hearing what the captain said, Chen Xin picked up a pair of binoculars and looked out. He saw that countless workers were working hard on the vast plain below, and the outline of a defense line had gradually emerged.


    Looking at the hot workers and roaring machinery below, Chen Xin couldn''t help sighing to the captain: "it''s difficult for these Europeans to build a defense line on the plain."


    "But what can we do? The whole of Eastern Europe is a super great plain. In addition to building a defense line from the Carpathians to the visva River, we can only retreat back to the hills of central Lucia to build a defense line. In that case, we have to give up the whole of Europe." Naturally, the captain knows very well about the defense line built by the forces of Lucia and Yanguo, so he is also quite moved.


    In fact, it is a helpless choice to build the defense line in its current position. Most parts of Europe are plain terrain. One part of the few mountains is the Alps where the front line of European countries against alien organisms is now located, and the other part is the Carpathians where the defense line of Eastern Europe is now located.


    It can be said that these two mountains can not be ignored or abandoned in any case if we want to rely on the advantages of terrain to resist alien creatures.


    Unfortunately, the Carpathians only cover half of Europe, and the north is still a plain, so we can only rely on the visva River in Poland as a defensive position.


    Looking at the defense line under construction, Chen Xin sincerely sighed: "I really hope they do white work. This defense line will never be used."


    "It depends on whether the Europeans are doing well this time. If the defense line in front of them is broken, humans can only retreat to this defense line for defense." the captain naturally sincerely hopes that, as Chen Xin said, this defense line is useless, but no one dare say that European countries will be able to withstand the attack of alien creatures on the front line.


    Before the United States helped European countries, they were almost overwhelmed.


    If the assistance of Yanguo and Lucia had not provided them with a large number of weapons that could effectively kill alien creatures, and the European aid fleet had provided them with battlefield fire support and reinforcements equipped with exoskeletons and electromagnetic rifles to fight the fire in the whole defense line, I''m afraid there would be a place where the European defense line has been broken.


    Even now, with the support of the European aid fleet, the whole defense line is still often in emergency and needs the fleet to fight the fire.


    This is one of the reasons why Chen Xin wants to come to Europe. He hopes to provide some help to the front line so that this line of defense can last longer.


    Let alone hope that this line of defense can completely block the attack of alien creatures, but at least this European line of defense cannot collapse until the construction of the Eastern European line of defense is completed and the civilians and population of European countries are evacuated behind the Eastern European line of defense.


    It''s just simple to say. Even Chen Xin doesn''t have a clue if he really wants to do this.


    Even if he really goes out and plans to use the system to upgrade the whole defense line, the whole European defense line is a huge defense line across the Mediterranean coast of Europe, starting from the Iberian Peninsula in the West and the Black Sea in the East. Even today''s Chen Xin is not able to upgrade it as a whole.


    Moreover, for Chen Xin, strengthening the defense line is a great waste of his ability. Developing new weapons in the rear to change the war situation is much more useful than strengthening the defense line and turning the front line into a meat and blood mill.


    "Take the liberty to ask, academician Chen, how are you going to help these Europeans this time?" the captain asked Chen Xin for a moment of curiosity.


    For Chen Xin, the captain has heard many rumors about him. Whether it is the land ship he now commands or the exoskeleton and protective clothing allocated to the fleet, it comes from Chen Xin''s research results.


    Therefore, for the impact of this important scientific researcher''s trip to Europe on the European defense line, not to mention the captain, even the ordinary crew on this land ship talk about this topic in their spare time.


    Some people think Chen Xin will build a powerful weapon, similar to a nuclear bomb, which can wipe out the battlefield.


    But more people believe that Chen Xin will provide the European defense line with powerful weapons that can be popularized to ordinary soldiers, so that they can kill more alien creatures, so as to stabilize the defense line.


    However, for Chen Xin himself, he has no ideas or relatively clear concepts. After all, he has not seen the specific situation of the European defense line and does not understand the war situation. He can''t start even if he wants to do something.


    Therefore, facing the captain''s question, Chen Xin can only smile bitterly and answer: "strengthen the armaments of European countries as much as possible so that they will not be too weak in front of alien creatures. That''s all I can think of before I really see the battlefield."

 Chapter 749

    When Chen Xin arrived at the station of the European aid fleet by land ship, even though he was used to seeing all kinds of big scenes, he was still amazed at the construction achievements they had made.


    It has to be said that after having 3D printing technology that can be applied on a large scale, Yanguo, which originally has a strong infrastructure capacity, seems to have been sealed. The construction capacity erupted, and even Chen Xin, who has a system, was amazed.


    The time for the European aid fleet to arrive in Europe was not long, and it was only more than a month before and after, but at this time, the station in front of Chen Xin had become a huge industrial production area.


    Giant mining machinery several floors high is in operation, directly excavating the mountains on one side. A large number of mountain rocks are broken and transported to another giant machinery behind the mining machinery for crushing and sorting through the conveyor belt.


    The selected ore is directly transported to a larger production facility for smelting, processed into raw materials, cooled on the conveyor belt with the help of the cold environment, and finally sent to a huge 3D printing field to be printed into huge building modules.


    These building modules are lifted by helicopters or cranes like building blocks and sent to places where they are needed. They are built into new buildings or facilities like building blocks.


    These raw materials will also be transported to other 3D printing plants to produce all kinds of products urgently needed at the front. Just as Chen Mo can see, several factories are operating in an orderly manner.


    Transport vehicles stop at the gate of the factory, and the products produced are directly loaded. When one vehicle is filled, one vehicle will be transported away, and there is no backlog at all.


    All this seems so amazing, but at the same time, it is so incredible that people can''t help lamenting the soul stirring power and charm of large-scale industrial production.


    Chen Xin once heard a saying that when science and technology develop to a certain extent, it is no different from magic.


    Once Chen Xin didn''t feel much about this sentence, but when he looked at all the amazing great undertakings created by human power, he had to say that it was as magical and amazing as magic.


    "That''s great! That''s what industrial production should look like!" Chen Xin is not the kind of unswerving industrial party, but in the face of this amazing large-scale industrial production, he can''t help becoming a believer in industrial greatness.


    You know, this large area of industrial facilities in front of us were built from scratch by the people of the European aid fleet with 3D printing facilities in more than a month.


    Even if the crazy devil of Yanguo''s infrastructure can build such a magnificent industrial production area in a month, and it is still expanding its scale, and the expansion speed is so amazing, the infrastructure capacity and industrial production capacity shown are really exaggerated.


    With the landing of the land ship, the people of the European aid fleet came to meet them.


    Of course, the most important thing is to welcome Chen Xin.


    After a simple and brief welcome, Chen Xin did not choose to rest, but couldn''t wait to pull the staff of the European aid fleet and let them take themselves to visit here.


    Just now I just looked down from the sky. Although I feel the magnificent momentum here, Chen Xin hopes to have an in-depth understanding.


    After all, his main purpose of coming to Europe is to deeply understand the situation here and upgrade and adjust the situation here, so that the European aid fleet can better support the European battlefield.


    Seeing Chen Xin''s attitude, the people of the fleet did not shirk it, so they led Chen Xin to visit the huge industrial base they had built from scratch in a month.


    "This was originally an open-pit mining area in Germany''s Ruhr Industrial Zone, with rich mineral types and reserves. However, before we came, Germany''s mining here had stopped, and we didn''t use this mining area again until we came." the staff introduced it to Chen Xin and said in a proud tone: "We brought a full set of industrial production drawings. It took us a week to build these mining machinery by relying on the 3D printing equipment on the aircraft carrier. After ensuring a stable output of raw materials, we allowed the aircraft carrier to manufacture new 3D printing equipment, and then built this industrial zone.


    At present, a large smelter is responsible for smelting ore into raw materials, which will be transported to one large, four small and five 3D printing yards here. The four small printing yards are responsible for producing electromagnetic rifles and supporting ammunition accumulated at the front line, and the large printing yard is responsible for producing building modules and other large equipment to expand the production scale. "


    Listening to the introduction of the staff, Chen Xin nodded with great satisfaction. In more than a month, these staff can really be proud of this achievement.


    However, after listening to the introduction of the staff, Chen Xin also found a detailed problem and asked him, "didn''t you produce exoskeletons?"


    "Technicians should have reported this problem to you before. At present, the main demand of European countries is electromagnetic rifles. They are eager to arm more front-line troops." the staff explained to Chen Xin and reflected the problem: "The electromagnetic rifles we provided to them were very popular, and the combat troops on the front line liked this new rifle that was compatible with their ammunition.


    In particular, it can penetrate the outer skin of alien creatures, so that ordinary soldiers can give better play to their firepower advantage, which greatly enhances the effective killing of alien creatures by the front-line defense line, so that they can better resist the attack of alien creatures. "


    "Sounds good, but what''s the matter with the supporting ammunition? If it''s not compatible with their ammunition, why do we produce ammunition?" Chen Xin asked new questions and sighed to the staff member: "It seems that the situation in Europe is worse than I expected! Ordinary soldiers can''t effectively kill alien creatures. I don''t know how they persist for so long."


    For this problem, the staff just smiled bitterly and said: "they arranged a lot of heavy machine guns on the front line, and even pulled out the antiques during World War II. Only by focusing on the defense line arranged by machine guns and anti-aircraft guns did they reluctantly block these alien creatures with the help of terrain advantages.


    As for ammunition, their standard ammunition mainly adopts reduced ammunition. Even with the addition of electromagnetic rifle, the lethality to alien creatures is still insufficient. The supporting ammunition produced here are full power ammunition, with higher initial speed, stronger penetration and better lethality.


    So we set up a production line to produce supporting ammunition and send it to the front line together with electromagnetic rifles. European countries are also making adjustments in this regard. Therefore, this is only a temporary emergency, and then it will be adjusted to the same electromagnetic rifle production line. "

 Chapter 750

    "Now we are still using 3D printing equipment to produce electromagnetic rifles. Do you plan to build a special production line?" Chen Xin followed the footsteps of the staff, visited this huge industrial base and raised new questions.


    The staff nodded and said, "in fact, we are already building. The building modules you see are for the production line. The reason why we use 3D printing equipment for production is mainly the 3D printing equipment we built first. The front line needs guns and has to be in a hurry, so let these 3D printing equipment first.


    When the production line is completed, the electromagnetic rifle will be produced there, and the 3D printing equipment here will be converted to exoskeleton, power armor, Titan and other equipment. "


    As European countries agreed to the requirements and conditions of the inflammatory country, the foreign trade version of power armor and Titan naturally put on the aid agenda.


    Although the European defense line needs electromagnetic rifles most, and even the demand for exoskeletons is small, European countries are still very clear that this is only temporary.


    As Yanguo handed over the relevant technical data of the foreign trade version of electromagnetic rifle to Germany and other European countries, so that they can also produce this weapon, the production capacity of electromagnetic rifle is also increasing, and the front line can get more electromagnetic rifles every day.


    When the demand for electromagnetic rifles is met, the demand for powerful equipment such as exoskeleton, power armor and Titan will naturally arise.


    Therefore, European countries have submitted demand orders to the European aid fleet after obtaining the promise of Yanguo to provide power armor and Titan. However, the production plans of the European aid fleet are now assigned to electromagnetic rifles. Production can only be carried out after the production line of electromagnetic rifles is completed and the 3D printing field is empty.


    After walking around, Chen Xin finally had a comprehensive understanding of the industrial base. While admiring the achievements of these staff, Chen Xin also asked with concern: "do you have any problems to solve now? I''m here to solve problems for you this time. You can raise any problems."


    "At present, the main problems we encounter are the shortage of raw materials and living materials, but there is little problem in production and construction." the staff naturally knew why Chen Xin came to Europe, so they didn''t be too polite, so they said the biggest problem facing the European aid fleet.


    While talking about these problems, the staff also explained to Chen Xin: "3D printing technology is really good, but with this technology, everyone wants to make everything and wants to build a complete industrial system here directly. However, Germany lacks petroleum as raw materials for chemical production, and the output of this mining area is limited, so the production raw materials on hand can not meet the production needs now.


    Although the German side has provided us with some raw materials, they also have to meet their own production needs, so the fleet is basically self-sufficient. "


    At this point, the staff can''t help feeling helpless. For large-scale industrial production, the biggest headache is undoubtedly the lack of raw materials.


    After all, reality is not like a game. If you find a piece of resources and send mining units to dig, one or two resources can meet all your needs.


    After many simplifications, electromagnetic rifles need fewer types of raw materials, but there are still more than a dozen kinds of raw materials, of which a considerable part belongs to chemical products. They need to be preliminarily processed into parts before they can be used in production.


    The lack of raw materials is indeed a huge problem and limitation, which is a headache for the staff of the European aid fleet.


    It is not that they did not want to solve this problem in the past. Even if Germany is reluctant, other European countries are willing to open more mining areas to the European aid fleet.


    But the problem is that the European aid fleet is short of manpower and mining equipment. Even if they get a new mining area, they are unable to mine it.


    As for the shortage of living materials, it is better understood that Europe is at war now, and all resources are inclined to the war. The production of living materials itself has been greatly affected. They are not enough to feed themselves. How can they have excess resources to supply the European aid fleet?


    If this problem had not been taken into account before they came to Europe, the European aid fleet had brought enough materials and had sufficient self-sufficiency, I''m afraid they would still have to ask for logistics supplies from home.


    This has led to the failure of the European aid fleet to expand the production scale. After all, expanding the production scale requires more manpower, and more manpower means more material consumption.


    In the case that they can only ensure the current scale of personnel consumption, they must consider logistics problems. It is simple to dispatch personnel from home, but it is obvious that this will also increase the material consumption of the fleet.


    After listening to the two questions raised by the staff, Chen Xin nodded to understand: "I understand the problems you said. These problems are not difficult to solve."


    Of course, there are ways to solve the problem. Of course, relying on domestic material transportation is a way. Now that there are freight land ships, it can be said that a stable logistics channel has been established between China and Europe. It is not too difficult to transport materials from China to Europe to ensure the operation of the European aid fleet.


    However, the carrying capacity of land cargo ships is limited, and they also need to carry other materials, which can not be used to carry all logistics supplies.


    Therefore, the fundamental solution is to carry forward the traditional skills of Yan people, open up wasteland and cultivate land, and be self-sufficient.


    This cannot be solved by the European aid fleet alone.


    Although they have also built planting greenhouses, it is obvious that if they want to expand the production scale and meet the needs of fleet logistics consumption, the output of greenhouses built by themselves is certainly not enough.


    However, this is the best problem for Chen Xin.


    As for the shortage of raw materials, we really have to dig mines.


    After all, reality is not a game. There is no way to turn out resources out of thin air, and there is no such thing as a mineral to meet all production needs, which is neither scientific nor magical. Therefore, mining and mining has become the primary problem that Chen Xin needs to solve for the European aid fleet.


    By meeting the demand for raw materials and allowing the industrial base built by the European aid fleet to operate at full capacity and produce more weapons and equipment, it can naturally better support front-line operations and enable European countries to persist for a longer time.


    As for how to mine and open mines, Chen Xin thinks some game settings may give him a good reference.

 Chapter 751

    "At present, the European aid fleet operates well, and the production and construction speed has reached the target set in the expected plan, but the shortage of production raw materials still affects their production efficiency." Chen Xin is contacting China in the communication room of the land aircraft carrier: "I have talked with the relevant person in charge of the fleet. The only mine provided to us by Germany is the mine where the fleet is stationed. Although it is said that we can further tap the production capacity and carry out destructive mining without considering sustainable mining to improve the production, the production capacity that can be improved is still limited.


    Moreover, according to the production demand, the mining area provided by Germany can only produce a limited number of raw materials, and other raw materials still depend on their supply, which is a great restriction on production.


    Therefore, I suggest that it is better to make use of the mining areas provided by France and England, and establish a complete resource output system in Europe to ensure the acquisition of production raw materials so as not to be controlled by others. "


    The senior management who was talking to Chen Xin listened carefully to his report and discussed it in a low voice before asking, "but now the European aid fleet is short of manpower and materials, and can''t continue to develop new mining areas? Or do you have any new ideas, academician Chen?"


    "Yes, judging from the current situation, we lack both necessary manpower and sufficient logistics materials. We really don''t have the ability to explore more mining areas to obtain raw materials." Chen Xin nodded without denying this: "So my idea is to enrich our own food and clothing, improve the logistics support of the European aid fleet, ensure that the material output here can meet the consumption of the fleet, and then expand the fleet''s manpower and explore resources."


    Speaking of this, Chen Xin paused and continued with a little self mocking smile: "of course, I think the leaders and others of the fleet have already thought of this plan. I also saw that the people of the fleet have opened up planting greenhouses and planted some crops that can mature quickly, but it still took too long to get results.


    As for the transportation of materials from China to Europe, although there are freight land ships to ensure the transportation of materials, there should be insufficient materials in China now? "


    For this problem, a leader in charge of logistics material supply nodded affirmatively: "although the intensity of the front-line battle has decreased recently and the defense against alien organisms is progressing smoothly, the material consumption is still very high. Most of the domestic materials are supplied to the front-line combat forces, and the people''s livelihood should be guaranteed.


    In addition to supplying the "purchasing plan", the materials we can take out can only ensure the basic consumption of the fleet. Although there is not no spare power, we should also consider possible emergencies and reserve them. "


    The so-called "purchasing plan" is what Li Yulong is doing. They are collecting all kinds of available technologies and materials in European countries with emergency food and living materials delivered from China, and have made some achievements.


    Because of this, a large part of the material quota sent by cargo land ships is allocated to them, not for the expansion of the fleet.


    Chen Xin has no opinion on this. The basic material supply of the fleet is still guaranteed, but there is no surplus material to expand manpower.


    As for how materials should be distributed and what is more important to the country, it is natural for people above to consider, and they do not need to talk about it.


    "So academician Chen, do you have any other solutions?" several senior leaders looked at Chen Xin with great interest. Since Chen Xin knew these problems and took it out, it was obvious that he must have new ideas.


    Chen Xin nodded affirmatively and asked several senior leaders, "have you heard of single cell protein?"


    "Single cell protein? Protein meat?" a senior leader seemed to have heard of similar things and said slightly: "before the disaster, someone proposed to build this artificial protein meat factory to produce synthetic food with artificial protein to meet food consumption, but the country did not adopt this scheme at that time."


    "It is a similar concept. Single cell protein is also called microbial protein. It is not a pure protein, but a cytoplasmic mass composed of protein, fat, carbohydrate, nucleic acid, nitrogen-containing compounds, vitamins and inorganic compounds that are not proteins." Chen Xin introduced to several senior leaders, but in order to facilitate their understanding, Chen Xin did not say too many professional terms: "In short, this is a kind of cytoplasm rich in protein and fat, and the cultivation speed is quite fast, and the production efficiency is thousands of times higher than that of animals and plants. In fact, it was a very mature technology before the disaster. In addition to protein meat, it is often used as a food additive to supplement protein, vitamins and minerals.


    Although this kind of food may not taste good, it is no problem to fill your stomach. It is non pathogenic to human body and rich in nutrition. It is a good synthetic food.


    Moreover, the cultivation is quite simple. Industrial and agricultural wastewater and waste, and even oil and natural gas related products can be used as production raw materials. The cultivation and production are quite simple, and can be industrialized and large-scale production. "


    "Yes, I remember. At that time, there was a proposal to build protein factories in various cities to produce single-cell protein to produce synthetic food and meet food consumption. We also considered this proposal at that time." at this time, another leader also remembered this matter and asked other leaders aside: "I remember everyone thought the plan was feasible at that time. How did you give it back?"


    "It was mainly the problem of raw materials. At that time, according to our estimation, industrial and agricultural production would be devastated, and it was difficult to obtain the raw materials used to produce protein. Therefore, after a comprehensive evaluation, I felt that the large-scale deployment could not provide enough raw materials, so I gave it No." a leader nearby seemed to have a better memory, I soon remembered it.


    However, although they initially rejected the plan, it was one moment after another. Now they listen to Chen Xin mention the plan. After a while of discussion, they all think it is a good plan.


    Only a few senior leaders were quite concerned and asked, "although this technology can indeed solve the problem of eating, where do you get the raw materials for producing these single-cell proteins? If it is transported domestically, it is better to transport food directly. Is there a channel to obtain food in Europe?"


    "Please rest assured that I have seriously considered this and there will be no problem." Chen Xin nodded affirmatively and transmitted his written report to several senior leaders through the network.

 Chapter 752

    The cultivation and production of single cell proteins is indeed a very simple thing. The raw materials they need are not complex.


    Such as agricultural waste, wastewater, industrial waste, wastewater, oil, natural gas and related products can be used as raw materials for the production of single-cell protein. Even more exaggerated, hydrogen and carbon dioxide can be used as raw materials.


    Before the disaster, these things were easy to do. For those production enterprises, they were worried that these waste residues and wastewater could not be treated. They were used to produce single-cell protein and synthetic protein meat.


    But these things are not so easy to deal with in the post disaster environment.


    First of all, industrial and agricultural production has been devastated, and the scale has shrunk sharply. The wastes produced by agricultural production have become valuable resources, which need to be used in available industrial production, but can not be used as raw materials for synthetic protein.


    Industrial waste is also in the same state. Most of the waste is pulled for recycling, and the products related to oil and natural gas should give priority to meeting the use needs of the national economy and the people''s livelihood, and there is no surplus to produce synthetic protein.


    This is the same whether in Europe or in China.


    However, since Chen Xin put forward this idea, he naturally has his own calculation.


    Although the English abandoned their own territory, as the sun never sets empire that once ruled the world, their sphere of influence once spread all over the blue star.


    Even after the sunset of the Empire, the territory of the former empire became independent into countries one after another, but these countries are still a federation. If they are combined, their volume is still equivalent to that of the former empire.


    Of course, when the sun never sets, it is naturally impossible to put it back. Although various countries still recognize the existence of the Federation, they just regard it as an organization, not a sovereign state.


    The English people know this, so they don''t expect to rebuild the empire that never sets. They just live by the legacy of the Empire.


    Thanks to the rich legacy of the former powerful empire, they can still come up with a lot of good things.


    For example, the distribution map of offshore oil resources in Europe.


    The ocean is rich in oil resources, which is well known. The exploitation of offshore oil was also a very prosperous industry in the past.


    But now, not to mention that the vast majority of drilling platforms have been destroyed by the previous disaster. The sea surface is frozen, the mining site is far from the land, and there is a lack of effective transportation and material support. Even if there are oil drilling platforms that can operate, they can no longer operate, and no one dares to stay on the drilling platform far from the land.


    However, this is not a problem for Chen Xin at all.


    It doesn''t matter if the drilling platform is damaged. Chen Xin holding the system can not only repair the drilling platform, but also make a technical upgrade.


    It''s not a problem to stay away from the land. The terrain needs to be considered when driving on the land. For the endless flat ice, isn''t the speed hurricane released?


    As for whether the ice thickness can withstand the weight of land ships and crack, it is not a problem. It can still fly!


    There is no need to worry about material supply. The consumption of living materials is not large. It can be solved by making supplies by landing ships in the process of transporting oil.


    The food problem is even better. The purpose of digging oil is to provide raw materials for the production of synthetic protein. Will there be no food?


    The only problem is the transportation of oil. After all, in the past, the oil extracted from the drilling platform was transported to the factory through pipelines.


    However, now that the sea is frozen, most of the original factories can no longer be used. Oil pipelines were useless in the past, let alone no one knows whether these oil pipelines can still be used now.


    Therefore, considering the actual situation, the best way is to establish a sub base near the mining site, directly use crude oil to cultivate synthetic protein and carry out petrochemical production, and then transport the produced products with land ships.


    For others or other countries, it is undoubtedly difficult and difficult to realize this plan.


    But for Chen Xin, all this is nothing to say.


    According to the resource distribution map provided by the English people, after the fleet sent helicopters to determine the situation of the drilling platform, Chen Xin began to manufacture his newly designed industrial ship with the help of the 3D printing field in the base.


    This is specially designed to exploit resources and open sub bases. The inspiration naturally comes from the design of base cars in the game.


    It is a land ship about more than 100 meters long, which can accommodate 50 people. At the same time, it is equipped with a 3D printing equipment and a perfect agricultural greenhouse and synthetic protein production facilities. It has good self-supporting capacity and can perform tasks alone for a long time.


    Moreover, this land ship itself is a huge ore mining equipment, which can directly mine open-pit mineral resources or conduct drilling operations, and then manufacture small robots to mine deep underground resources.


    The mined resources can be directly processed by the smelting equipment on board, processed into raw materials, and then supplied to 3D printing equipment to produce the required equipment or facilities.


    It can be said that this land-based ship is really like the base car in the game. It can establish a relatively simple industrial base by relying on only one land-based ship.


    After the design of this land-based ship was completed, the drawings were quickly sent back to China, and the senior management was naturally very satisfied with it. After all, not only Europe needs this industrial ship like a base car, but also a large number of mines and mines abandoned in China because of insufficient manpower and poor mining conditions, but also such industrial ships are needed to reuse them.


    Compared with dispatching a large number of people to restore mine operation, and then transporting a large number of materials to maintain security, relying on the self-sufficient mining resources of an industrial ship will undoubtedly save a lot.


    As for the resource consumption caused by the base construction of industrial ships, compared with the resources mined by them, this is undoubtedly a cost-effective deal.


    Therefore, the senior management soon adopted Chen Xin''s design, which not only allowed the domestic production of such industrial ships, but also sent new reinforcements to the European aid fleet, so that they can have people to expand sub bases and obtain more resources according to Chen Xin''s plan.


    Even after careful domestic evaluation and consideration, the diplomats of the European aid fleet went to the officials of European countries with the introduction ppt temporarily made by Chen Xin and sold them this industrial ship.


    After all, for European countries, this industrial ship is very useful for them to resume production and support the battle of the European defense line.

    The North Sea, a sea area between the English and Northern European countries, is almost the same size and area as the English mainland.


    It was once an important source of fishery resources in Europe, one of the four largest fishing grounds in the world, and also an important source of oil and natural gas resources in Europe. Chen Xin of the world has reason to believe that it will be a new era for mankind to step into the sea of stars.

 Chapter 754

    Because most of the drilling platforms are submerged under the ice, there is no need to reuse them.


    So after the industrial ship landed, it began to drill again.


    Tuo Chenxin designed a drill for the industrial ship. In addition, the ice layer is not difficult to drill. The Beihai oilfield belongs to a shallow sea oilfield. Re drilling did not bring any trouble to the industrial ship.


    And after drilling dozens of meters of ice, they were surprised to find that there was life in the sea water flowing under the ice.


    "What''s the situation under the ice?" Chen Xin asked with great concern and curiosity as he watched the staff operate the equipment to explore the ocean under the ice.


    "At present, in addition to the microorganisms found in the detection process of the seawater we extracted before, sonar has also found some fish schools and marine organisms." the staff replied to Chen Xin and explained by pointing to the picture displayed on the instrument screen in front of him: "It should be a school of fish, but the number is not large. It should be that the previous disaster has caused serious damage to the marine ecology of this sea area. Although it has been restored in the past two years, the overall number is still rare."


    Hearing the staff say so, Chen Xin frowned and thought for a moment and asked him, "can these fishery resources be exploited and utilized now?"


    "I''m not a professional, so I''m afraid it''s not easy to comment, but judging from the current situation, it''s still not suitable for large-scale fishing." the staff shook his head and disagreed with the exploitation of these fishery resources that have just recovered a little, and he said with humor: "And it can''t be mined. It''s OK to drill a hole in the tens of meters thick ice. It''s unrealistic to want to drill for fishing."


    "That''s true, but we can''t deny this possibility first. Send the data back to China and let relevant professionals make an assessment to see whether the fishery resources here can be used." although Chen Xin also feels that it''s unrealistic to dig through the ice to fish, it''s still very beneficial if these fishery resources can be used.


    So he still asked the staff to collect the data and send it back to China for professionals to judge.


    In addition to fishery resources, the most important thing for them to come to the North Sea is to exploit oil.


    Although relying on the oil field distribution map provided by the English people, they easily drilled a well and drilled oil, the drilling platform also needs to be built by them, which undoubtedly increases the difficulty of exploitation.


    After all, no country in the world has ever tried to drill and exploit offshore oil on the ice.


    Even lucians are drilling on the sea, so they don''t repair the drilling platform on the ice.


    However, it is difficult for Chen Xin to let the industrial ship lay a basic mining platform by relying on the resources brought from the industrial base, and then Chen Xin upgraded it to adapt to the current ice environment. Even if the construction of this oil well is completed.


    Only because the supporting facilities have not been completed and there is no oil pipeline to transport the extracted oil, so the oil well has not been officially put into operation.


    Knowing that an oil well was secured on the side of the industrial ship, the base soon sent them new materials with small cargo land ships, so that they could start building petrochemical equipment and important synthetic protein factories.


    Compared with oil exploitation, the sea water under the ice provides convenience for synthetic protein factories, which is rich in nutrients.


    After all, before a large number of marine organisms died, a large number of dead fish bodies provided rich nutrients for the whole ocean.


    Although this will cause marine eutrophication and affect marine ecology, under this situation, the original marine ecology has long collapsed. Now it can be said that it is the stage of the establishment of a new ecosystem, and this eutrophic ocean has no great impact.


    Although only a few marine organisms can adapt to such an environment, these seawater can be used as raw materials for the production of synthetic proteins.


    Although crude oil was used as raw material for the production of synthetic protein according to the original plan, Chen Xin doesn''t mind modifying the scheme since there is nutrient rich seawater available.


    After all, oil is not only an important industrial resource, but also an important energy source to support human civilization. Perhaps Yanguo uses nuclear energy on a large scale because of Chen Xin''s activity, reducing the energy consumption of oil, but there is still a great demand in industrial production.


    As for European countries, not to mention, European countries still at the original stage of energy structure are extremely hungry for oil.


    If we can obtain more oil resources and replace the inexhaustible seawater as the raw material for the production of synthetic protein, it can be said to be better.


    Therefore, Chen Xin quickly adjusted the design of the synthetic protein factory and changed to seawater as the main production raw material.


    For others, it may be necessary to completely overthrow and redesign, but for Chen Xin, this is just an idea. It doesn''t even matter if it is built. The problem can be solved by upgrading.


    With the help of Chen Xin, the punishment base was soon completed and finally officially put into operation.


    The oil produced by the oil well will be transported to the nearby chemical plant for fractionation. The various products obtained will be loaded by categories and transported back to the industrial base by small freight land carrier together with the synthetic protein food produced by the synthetic protein factory.


    Various petroleum products are used as industrial raw materials to meet production needs. After secondary processing, they become new production raw materials and products, and finally produce weapons and equipment and other supplies needed by the front line. They are connected with the synthetic protein food after secondary processing and transported to the front line.


    These supplies are tantamount to providing charcoal in the snow for the front line. Although the quantity is not large, the precious fuel can not only make many armored forces and air forces lying prone due to lack of fuel supply operate again, but also bring warmth to the soldiers on the front line.


    After all, there is no energy tower and heating system provided by Chen Xin on the European defense line. In addition to burning something to keep warm, they can only keep warm by fortifications such as bunkers.


    As for the others... A shake may warm the soldiers a little.


    Although the taste and taste of synthetic protein food are indescribable, it is good to have something to eat and fill the stomach for the front-line combat forces who have been short of food for a long time. Who cares about the taste and taste of these synthetic proteins?


    For example, in World War II, the Yankees'' canned lunch meat was notoriously bad, but when these things were transported to the front line, they were still very popular. After all, it could fill the stomach.

 Chapter 755

    With the operation of the first logistics base in the North Sea, the supplies produced by it began to be continuously transported to the front line by small cargo land ships.


    As their supplies were transported to the front line, these small land ships immediately became the most popular presence in the front-line army.


    Every time they appeared, everyone on the front line cheered, which even exceeded their previous welcome to the frigate providing fire support for them. Just as the scum man likes the new and hates the old, there is always a new wife to replace the original wife.


    However, the joke is a joke. Because of their high frequency of occurrence and can provide supplies that can effectively improve morale, the popularity of small cargo land ships transporting logistics supplies is indeed much higher than that of escort land ships that only occasionally appear in the rescue site when the defense line is in danger.


    After all, what Yanguo has invested in the European defense line is only the three frigates and carrier aircraft on the land aircraft carrier that arrived in Europe with the European aid fleet.


    Although the effective operational attack range of aircraft carrier can reach a radius of 1000 kilometers, the limited number of ships and carrier based aircraft is undoubtedly seriously insufficient compared with too many targets requiring support and attack in the long defense line.


    This leads to the possibility that the front combatants are far less likely to receive air fire support than to receive supplies from cargo land ships.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Bob is an ordinary corporal of the English army. He and his company are responsible for guarding a fire point in the mountains in the middle of the line of defense.


    This firepower point is the most important strategic support in this section of defense. In addition to the company of Bob who is responsible for Garrisoning the firepower point, a French infantry battalion and an Italian infantry battalion are also arranged on their two wings.


    It is called firepower point, but in fact it has been built into a solid bunker or semi underground fortress.


    Because in this fire point, in addition to Bob''s company, there is an artillery company responsible for providing fire support for the whole defense line.


    At the same time, it is also the logistics supply place for everyone on the whole section of the defense line, storing all their supplies. The soldiers who rotate can eat, rest and sleep here, and then prepare their weapons before they go into battle.


    If they lose this firepower point, they can only stay in the trench dug out by themselves in the low temperature environment of tens of degrees below zero, shivering and gnawing at the frozen food, rather than having a hot soup to warm their bodies with their intestines and stomach.


    The environment on the front line is indeed bad, and supplies have become increasingly scarce some time ago. In addition to sufficient ammunition, there is less and less food to eat.


    Bob and some of his teammates are even considering whether to put an alien creature across the defense line and kill it to see if they can cut some meat to eat.


    Of course, their ideas were not put into practice, not that they could not do it, but that the European aid fleet of Yanguo came, which brought them fire support and new supplies.


    This undoubtedly greatly changed the situation on the front line, and made Bob and his comrades in arms not really have to catch alien creatures to eat, and their logistics officers don''t have to grab the transport team to deliver supplies every time, just like begging for more food.


    However, although the supply situation has been greatly improved, the long-term continuous battle has still brought many impacts and problems to them.


    The damage of equipment, casualties and lack of logistical supplies once made the morale of the front line extremely low.


    If we don''t know that they can''t hold on, it means the destruction of mankind, and the alien creatures ahead can''t accept surrender. I''m afraid they can''t hold on long ago.


    "Hey, Bob, do you have anything else to eat? I''ll exchange this with you." there was another round of rotation. Bob and several comrades in arms left the trench in front and returned to the warm fortress. His comrades in arms couldn''t wait to beg Bob for food.


    Maybe he had a relationship with his roommate in Yanguo when he was in college. Bob formed the habit of often carrying something to eat.


    At that time, it was to avoid being hungry when my roommate in Yanguo cooked. Now it has become an effective means to save lives.


    After all, there is food in your pocket. In today''s environment, it can really save your life.


    Hearing the inquiry from his comrades in arms, Bob touched his body and then took out an energy rod. This is the most popular thing in the supplies sent by the Yanguo people last time. Unfortunately, the quantity is not much. This is the last one left by Bob.


    "This is the last one." he threw the energy bar to his comrades in arms, then took half a packet of homemade cigarettes thrown by the other party, looked at it and put it in his pocket.


    Although they are all comrades in arms who can help each other block the bullets, these food has already become a very strong hard currency. Even if Bob and they can only exchange between comrades in arms or exchange something else with the people in the supply team.


    For example, half a pack of homemade cigarettes thrown to him by his teammates was bought from the supply team. Although this thing was just rolled with a piece of paper and some unknown leaves were dried, it was OK for big soldiers like Bob.


    "It''s supposed to be the day to deliver supplies," Bob asked his teammates who were eating the energy bar.


    Because the front line consumes a lot of ammunition every day, the supply of ammunition is guaranteed even if the food supply is insufficient. The supply team will still send supplies regularly without any delay.


    "Yes, I don''t know how much food they can send this time. If I say, I should hand over the logistics supply to the Yanguo people. What they are best at is farming!" Bob''s comrade in arms swallowed the food in his mouth and boasted his knowledge to Bob: "I tell you, when I fought in the Middle East, I saw the peacekeeping troops of Yanguo people. Do you know? They even cultivated wasteland around the barracks to grow vegetables! Grow vegetables in a place full of sand in the Middle East!"


    Hearing this from his comrades in arms, Bob suddenly missed the taste of the vegetable salad made by his mother before. Since the damn disaster came, the English Channel abandoned the local land, and Bob has rarely been able to eat fresh vegetables.


    "Do you think there will be fresh vegetables in today''s supply? I heard that Yanguo people built a greenhouse..." just as Bob was chatting with his comrades in arms, a huge roar interrupted their conversation.


    A small cargo land carrier has arrived over this fire point and is slowly landing.


    Seeing the appearance of the cargo land ship, everyone on the whole fire point and the surrounding defense line could not help cheering.


    They know that the emergence of land ships means that they can get quite rich food supplies today, not only shells sent by the supply team.

 Chapter 756

    "Welcome! Friend!" Bob''s superior warmly welcomed the Yanguo staff who came down from the land ship. His warm and friendly appearance made Bob think he might not be so enthusiastic about his father.


    However, Bob didn''t think it was wrong for his superiors to treat Yanguo staff so warmly, because on the other party''s ship, they had the supplies they urgently needed, especially the food provided by Yanguo people, which was much better than those transported later.


    It''s a little ugly. The food supply from the rear is like pig food for pigs... No, it should be said that pigs before the disaster ate better than this.


    Dark potatoes are mixed with something that is hard and dry and can be used as a stick to make French bread. This is the food during World War II.


    But the things sent by Yanguo people are different!


    Compressed biscuits and energy bars taste hard, but they are full and anti hungry. The key taste is very good. They are much more delicious than those magic sticks that don''t know what they are mixed with.


    As long as the dehydrated vegetables are soaked in boiling water, and then put the seasoning package sent in, it is a very good vegetable soup!


    In this cold and dark era, a bowl of hot soup that can warm the stomach and body and mind can no longer be great!


    Not to mention that there are emergency food bags in the supplies of Yanguo people, which can eat real meat!


    Although some guys who understand Chinese translate that what is written in the ingredient list is mouse meat, for Bob and them, as long as it is meat, they are going to catch alien creatures and come back to roast them. Just mouse meat is not a problem at all.


    "What good things did you bring today?" Bob''s superior asked him eagerly after welcoming the staff of Yanguo.


    The supply of Yanguo is now the most popular thing in the whole European defense line. Anyone will cherish the opportunity to get supplies from them.


    The staff member seemed to be used to the enthusiasm of these European soldiers, so he smiled at each other and said: "You are lucky today. We have built a new logistics base in the rear to produce synthetic protein meat while mining oil. Today, I have emergency food for gasoline and synthetic protein meat processing, as well as some weapons and equipment. It depends on what you need, and I also have some ammunition."


    "You can provide weapons and equipment?" the Officer immediately widened his eyes and showed an expression of disbelief.


    It''s no secret that Yanguo people have better military equipment. In fact, as long as they see the protective clothes and exoskeletons worn by Yanguo people and the power armor of their escorts on board every time, no front-line officer doesn''t envy and ask about it.


    However, the answers they get are similar, that is, they are organizing rear production, talking with officials of various countries about technology transfer, and only provide a small part of electromagnetic rifles to the troops most in need of weapons.


    As for the coveted power armor and exoskeleton, the Chinese people said they had not brought the finished products, and the countries had not reached a technology transfer agreement and could not provide them.


    Now the officer actually heard from the staff of Yanguo that they can provide weapons and equipment. How can it not surprise people!


    Although food can effectively boost morale and enable soldiers to fight better, it is nothing compared with the advanced military equipment of Yanguo people.


    "What can you provide? Your exoskeleton or those handsome power armor?" the officer asked eagerly. Perhaps he thought these might be too extravagant, so he added: "even if only electromagnetic rifles are OK!"


    "Oh, don''t worry, there are all!" however, the staff of Yanguo, who had been an officer before and refused to offer any conditions, was particularly good at talking this time, and introduced to him: "we brought 100 sets of exoskeletons, 20 sets of power armor, 500 electromagnetic rifles and supporting maintenance parts this time.


    In addition, I have 200 barrels of gasoline, 150 barrels of diesel, 50 barrels of kerosene, 20 tons of emergency food made of synthetic protein meat, 10 tons of dehydrated vegetables, and more other food supplies, about 100 tons.


    These can be provided to you, but I have to go to five strongholds that need supplies this time. I don''t have much to give you.


    In addition, the power armor needs special technicians to maintain. If you want, I''ll leave a technician here. You can let someone learn how to maintain it from him, and then I''ll pick him up when I go back. "


    "Enough, enough! Even if only a part is enough! Can I have it all?" the officer looked very happy at the moment. He had long been greedy for the exoskeleton and power armor of the Chinese people. Now he can finally get a set of soldiers to arm his own men, which made him almost faint with excitement.


    The staff of Yanguo didn''t say anything about it. They just nodded and asked the people on the land ship to start unloading.


    "I can give you five tons of emergency food, two tons of dehydrated vegetables, 20 tons of other food supplies, 50 electromagnetic rifles, 20 sets of exoskeletons, and only five sets of power armor. I will leave enough repair parts, and let our people help you build a repair station to teach you how to use and maintain these things." At the same time, the staff of Yanguo said, huge boxes were being unloaded from the cargo hold opened by the land ship.


    The officers quickly organized people to carry these materials. Although there was still a war ahead, there were still many soldiers who took turns to rest in this firepower point. At this time, they were carrying these materials with enthusiasm.


    It is not easy for the supply ship of Yanguo to appear once. It may not be possible to meet it in the next month or two. Especially this time, they provide such abundant supplies, which is more than three or four times as much as usual, which makes people more excited.


    In addition to the rich food, the most exciting things at this time are the electromagnetic rifles and exoskeletons just taken out of the carrier, as well as the handsome power armor.


    The officers quickly selected a group of trusted elite soldiers to learn how to use these new equipment, but the people of Yanguo said that the people they left will only stay until the supply ship returns, and their own people must learn how to use these things in a short time.


    Bob''s luck was very good, because he had the habit of saving food at ordinary times. Instead of being hungry, he looked quite strong. In addition, he performed very well in ordinary times and was selected to use one of the sets of power armor.


    Looking at the power armor provided by Yanguo people, Bob couldn''t help getting excited. Some were at a loss. Under the guidance of technicians sent by Yanguo, he took off his equipment and put on the power armor for the first time.

 Chapter 757

    Because it has passed a support agreement and obtained what it wants, or is in the process of obtaining it, China has finally opened its arsenal to European countries to provide comprehensive support.


    All kinds of domestically produced foreign trade heavy weapons and explosives of various equivalents were transported to Europe by cargo land ships, and then quickly distributed to the front-line forces under the treatment of the logistics supply departments of European countries.


    Although these belong to the equipment before the disaster, for European countries, when the equipment such as electromagnetic rifle is not enough to be distributed to everyone, these things are still great. At least they can use these things to kill alien creatures.


    In the industrial base of the European aid fleet in Europe, they finally began to produce exoskeletons, power armor, and the most important foreign trade version of Titan.


    There is nothing to say about exoskeleton and power armor. Reduce the output, replace the nuclear battery with a battery, reduce the duration of combat, and replace the built-in operating system with a special version that is not so easy to use. Basically, it can be delivered to the European army.


    As for the relevant design drawings and other things, they are also handed over to the military production plants still in operation in European countries, so that they can also produce these things.


    Of course, all the design drawings have been modified, not to mention cutting corners, but at least there is a difference of one or two versions from the model used by Yanguo.


    After all, Yanguo only provides support for them, not to teach them how to produce their own trump products.


    Titan, a powerful military equipment, did not provide design drawings or other things to European countries, but was produced in a small amount by the European aid fleet, and then provided to the armies of European countries together with other equipment.


    This is mainly because Titan wants to use nuclear batteries, but Yanguo obviously will not hand over the technology of nuclear batteries to Europeans.


    The original batteries on these Titans are enough for them to use for a long time, so this time, Yanguo directly sealed the battery compartment when these Titans leave the factory. If there is no power or damaged, they need to return to the factory for overhaul instead of letting Europeans replace the batteries themselves.


    Europeans certainly have opinions on this, but when they sold aircraft to Yanguo in those years, they simply welded the aircraft engine to death and refused to dismantle it. Now Yanguo is just a little tribute to the classics.


    Of course, apart from these discordant parts, Europeans are happy that they have finally received these strong support.


    Titan, in particular, watched the four legged spider Titan easily cross various obstacles on the test site, and the various powerful weapons installed also destroyed the pre-set targets in the test site very efficiently, which made the military representatives of European countries who came to watch the test very satisfied.


    However, for several technicians of Chen Xin and Yanguo who stood aside, they were not very excited about the Titan in front of them, but more concerned about the gap between it and the two titans being used in China.


    "The spider chassis has a good walking ability. Pay attention to collecting more data, which can provide data support for the later development of Titans for mountain warfare." Chen Xin ordered a staff member nearby and asked with concern: "what is the combat effectiveness ratio between spider, general-purpose and male?"


    "The manufacturing cost is higher than that of the general model, but the combat effectiveness is only equivalent to that of the Gongshi model." the staff on one side turned over the report in their hands and replied to Chen Xin: "It is mainly because of the problem of weapons and equipment. Although the spider type adopts the same weapon arm design as the Gongshi type, it has no hot plug function and can only use fixed weapons, which affects its combat capability.


    Moreover, NATO ammunition and weapons are used. There are still some gaps between the weapons we use now, which also leads to the gap in combat effectiveness. However, on the whole, it is enough to fight against alien creatures. "


    Because of the version for Europeans, Chen Xin and researchers did not install too many advanced technologies on the spider Titan.


    The bipedal walking mode tested on the two titans in Yanguo is not used on the spider Titan. It uses the quadruped walking mode, and the weapons are just an inseparable rotary tube machine gun and a 75mm recoilless smooth bore gun.


    Of course, considering the needs of use, Chen Xin added a rocket launch nest on the spider''s shoulder, which can be regarded as improving the Titan''s combat capability.


    Compared with bipedal walking mode, quadruped walking mode undoubtedly consumes more resources, but it is relatively more stable, and it is better for the passage of complex terrain. There is no difference between advantages and disadvantages.


    Chen Xin adopted this chassis on the Titan for Europeans mainly to adapt to the mountainous terrain on the European side. Of course, there are two more legs and the manufacturing cost increases accordingly.


    Moreover, the control procedure is also relatively more complex. After all, it needs two more legs, and the coordination needs to be handled well.


    As far as weapons are concerned, they are actually enough. Although they are not as hot as the Gongshi type used by Yanguo, nor as general-purpose, that is, hand-held weapons can be changed at any time, there is nothing wrong with fixed weapons without dealing with a complex and changeable environment.


    Moreover, vehicles and weapons such as tanks were fixed in the past. No one said that tanks could replace the main gun with heavy machine guns.


    So these Europeans are very satisfied with the spider Titan in front of them, but it is too expensive and needs to consume too many resources. They have only placed a small batch of orders for the time being, rather than a large batch of orders like electromagnetic rifles and exoskeletons.


    These problems have nothing to do with Chen Xin. It''s a headache for diplomatic staff.


    After chatting with the staff for a while, he looked at several Titan drivers standing aside. They were the Titan team following him. Now they were driving spider Titans for testing. After all, there were no suitable drivers in Europe, so they had to go on.


    "What do you think of this Titan?" Chen Xin wants to listen to the opinions of professional drivers. After all, they are the actual users, and their opinions are more valuable for reference.


    "A fairly practical Titan. The four groups walk well in stability and terrain passing ability. If I were allowed to drive, I would be willing." several drivers looked at each other before one of them spoke: "However, the weapon system must be upgraded. There is no dense array to resist the attack of capsule and bubble body. Even titans are still easy to lose."

 Chapter 758

    The arrival of new equipment has made a qualitative leap in the combat effectiveness of the combat forces on the front line.


    These new equipment and the logistical supplies provided by the Yanguo people have finally allowed the combat troops on the front line to breathe a sigh of relief. There is not so much pressure. The defense line is no longer in three emergencies a day. There is a risk of being broken through and needs to fight the fire.


    The stable defense line also relieved the countries behind the defense line.


    Before, they were all holding on with their teeth, for fear that after the defense line collapsed, it would be their turn to feed those alien creatures.


    Now the defense line has finally been stabilized with the support of Yanguo people, and these most closely related countries naturally feel the deepest.


    Although it''s not time to relax, at least you don''t have to be in a panic all day, even if you receive a report of the collapse of the front line one day, and then feed alien creatures.


    This also makes the officials of these countries more grateful for the support of Yanguo, and hopes Yanguo can provide them with more assistance.


    Therefore, they not only opened more mine resources to Yanguo, but also paid no attention to the full ship of materials on the cargo land ship.


    If a ship of goods can be exchanged for a ship of aid... No, even half a ship of aid is profitable for European countries now.


    After all, a little bit of resources can be exchanged for more aid from the United States to keep their citizens alive. Whether this long-term deal is cost-effective or not, these Europeans still know.


    With the departure and return of the cargo land ship, the energy tower core carried by Chen Xin was also opened to European countries to provide them with energy tower construction services.


    This powerful geothermal heating equipment immediately aroused extremely strong interest and demand in European countries. After all, no matter how well the front line fought, the impact on them was not so direct, but the improvement of their living conditions by this heating equipment was quite intuitive.


    This undoubtedly makes European countries greedy. They have to bite their teeth again and take out good things from their pockets to meet the appetite of Chinese people.


    After all, compared with armaments, heating equipment is directly related to itself, and belongs to the rigid demand at the same level as armaments. It can be said that it is even more important than armaments in priority.


    The number of energy tower cores in Yanguo''s hands is limited. Whoever grabs it first will undoubtedly have priority.


    For these Europeans, they can still unite in the face of the threat of alien invasion, but when the crisis is lifted a little, their tradition of infighting appears again.


    Everyone wants to get the energy tower first, but it is obvious that Yanguo people can not meet everyone''s needs at the same time, nor can all energy towers start at the same time. In order to obtain the priority, they can only please Yanguo people so that they can get the core of the energy tower first.


    Chen Xin naturally didn''t bother to take care of these things. After he handed them over to diplomats, he was concerned about the domestic situation during this period of time.


    When Europe has made remarkable achievements through the excellent performance of industrial ships, China is also putting industrial ships into use, and has also made modifications according to the drawings sent back by Chen Xin, so that industrial ships can be applied to more fields.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Lao Hu, with a dozen men he pulled, looked at the snow covered Valley in front of him. He was a little uneasy, but he also had hope.


    This will be their new home in the future. Although there is nothing now, everything will be there as long as they work hard with their own hands.


    "Big guy, let''s get to work! First unload the equipment on the ship, and a few people put on mining clothes to explore the way with me, and the rest beat up the foundation first." Lao Hu turned and shouted to the dozen men around him, explaining the task: "Women and old people take good care of their children. Don''t let them run around. Get together and take online classes on time. We can''t waste our studies! We''ll be wronged these days. We''ll live on the ship first. When we open the mine and have the first harvest, we''ll go to the state to exchange the living cabin and build our own new home!"


    "Just wait for Lao Hu! We can''t wait!" the men on the side cheered and coaxed at the same time.


    Their passionate faces, although also with a trace of anxiety about the future, are more about the good hope of a new life.


    Lao Hu and his more than a dozen companions are a mining team. They contracted the valley in front of them, a small iron mine before the disaster.


    The state leased them a miniaturized industrial ship after transformation to enable them to mine this iron ore. The state set a monthly mining amount for them, and the mined ore was taken away by the state according to the mining amount, and the remaining 30% and the excess were owned by themselves.


    Of the 70% taken by the state, 50% is the contracting cost of iron ore, and 20% is the rent of the industrial ship. Two years later, the industrial ship will belong to Lao Hu and them.


    The points they get themselves can be converted into corresponding proportions of points and exchanged with the state for various living materials. From living quarters, power supply facilities, heating equipment to small ecological domes, and other living materials, they can be exchanged with the state through points.


    These iron ores were also proved by the state before the disaster. They were originally contracted to private mining.


    But now the disaster is coming, and the original contractor obviously can''t do it anymore. Naturally, the state has to contract the mine to people willing to mine.


    In addition, in order to enable these people to mine these small mines, the state has specially reduced the industrial ship, removed the 3D printing equipment and greenhouse cabin, and provided them with several sets of exoskeletons originally developed by Chen Xin for mining and some miniaturized mining equipment, so that they can use these things to re mine the mines.


    It can be said that as long as you work hard, you can live a rich and comfortable life in this way.


    Lao Hu was such a person. He took more than a dozen people he knew who were willing to fight a better life with him rather than being trapped in the shelter, and took them and their families to contract the iron mine to the state, intending to work hard for the future of himself and his children.


    In the past, they may not have the courage or the opportunity, but now the country has prepared everything. All they have to do is be brave and use their own hands to open up a future. For these men, if they dare not again, they will really be a loser.


    In fact, it was not just Lao Hu and them. At this time, all the 200 small industrial ships provided by the state in the first batch had been rented out and scattered to 200 small mines all over the country.


    These people who rent industrial ships and contract mining will use their hard work and sweat to open up a better life for themselves and contribute to national construction.

 Chapter 759

    In the wind and snow, a cargo land ship was moving forward.


    Today''s weather is a little bad. The snowflakes rolled up by the strong wind are constantly beating on the glass of the bridge of the land ship, which seriously affects the sight of the Jiang Fang.


    However, Jiang Fang is not worried about any obstacles and dangers. Although the wind and snow outside is heavy, it will not have any impact on the cargo land ship where he is now.


    What''s more, the land ship is now suspended in the air 500 meters away from the ground for cruising. Even if there is anything on the ground, it will not hinder the cargo land ship unless it is a mountain that can''t be seen by the river and can''t be swept out by the radar.


    Of course, even so, Jiang Fang did not relax his vigilance. As a navigator, he was still very conscientious in watching the front and the radar display on the console, so as to timely find the obstacles to be avoided and avoid the danger of his cargo land ship.


    "Xiaojiang, how long do we have to get to the next mining area?" I just went to dinner. At this time, I returned to the bridge and saw that Jiang Fang was still staring outside, so I asked him.


    "We are about 50 kilometers away from the next mining area, and it will take about 15 minutes to fly." Jiang Fang answered the captain''s question and asked curiously, "Captain, how did we get this trip?"


    Because it was the pilot, when the ship stopped in the previous mining areas, Jiang Fang stayed on the bridge and did not go down to help load and unload the goods. Therefore, he did not know what they had gained from this trip.


    Seeing the captain, Jiang Li wanted to make up for her curiosity.


    For this question, the captain replied with a smile: "the harvest is good. All mining areas have been running smoothly, and basically exceed the mining amount specified by the state. Our cabin is almost full."


    "That''s really good!" Jiang Fang couldn''t help being happy.


    Although their income is not linked to these harvests, Jiang Fang is sincerely happy to be able to fill the cargo hold.


    "Yes, I heard that Lao Wang''s ship on the European route is also full of cargo this time, loaded with urgently needed materials in China." the captain was also talking about the news he heard.


    Although he only recently became the captain of the cargo land ship, he also knew each other and had contacts with the captains of several other cargo land ships.


    "European route? Captain, I heard that the subsidy for running European route is higher. Is it true?" Jiang Fang was curious when she heard the captain mention European route.


    As a pilot of a cargo land ship, he can receive additional materials as a subsidy every time he sails. This is the main source of income for Jiang Fang and the guarantee for him to support his family. Naturally, he pays special attention to matters related to it.


    The captain didn''t care about this, but joked and said, "why? I don''t think this route makes money and want to run the European route?"


    "Hey, Captain, you know, I have two children and parents to support. It''s always good to earn more." Jiang Fang was a little shy and explained with a smile.


    "I know your family has a heavy burden, but I still don''t recommend you to run on the European route." the captain understood Jiang Fang''s idea very well, but he didn''t want this young man to run on the European route: "There is a war in Europe, and the European route is still dangerous. Lao Wang and his team were attacked by flying alien creatures last time. If they were not escorted by frigates at that time, they would be in danger.


    Your family has a heavy burden. I can understand that you want to earn more. But if you want to do so, you have to consider it for your family. You are the main source of income in your family. In case something happens to you, who will support your wife and children? "


    Speaking of this, the captain also became serious and sincere, patted Jiang Fang on the shoulder: "of course, if you really want to run the European route, I can help you tell Lao Wang, but I still hope you think more and don''t take the risk when you see that the European route makes more money."


    Although the captain''s remarks seemed timid and conservative, Jiang Fang knew that the captain was doing it for his own good.


    European routes are more subsidized precisely because they are more dangerous.


    Although according to the national report, the situation on the European battlefield is gradually improving, Jiang Fang also knows that it is still very dangerous there. Although attacks by flying alien creatures do not often occur, they will always encounter one or two times on this route.


    Before that, he heard that the captain mentioned that a crew member of Lao Wang''s ship was injured by an alien attack.


    This makes the Chinese larva have to bear their own ideas and think more about the consequences.


    However, while considering whether he should give up the idea of running European routes, Jiang Fang couldn''t help asking the captain, "Captain, do they contract these small mines to make money? I heard that the country wants to draw 70% of the money! There is some money?"


    "Why can''t you make a profit? Don''t think the country''s pumping is high. You should know that their industrial ships for mining are national, and their mining equipment is also national. Even the mines are contracted by the state, and 70% pumping is very reasonable." the captain himself was excited about contracting mines and naturally knew something: "As long as they work for two years, they only pay 50%. That industrial ship is theirs, and the rest of the ore they dig out is their own!


    These minerals can be exchanged for all kinds of good things provided by the country. My mouth watering! If I didn''t need to run a boat, I would like to pull a group of brothers to charter a mine and work hard for two or three years to have everything! "


    "Captain, why don''t you go? If you want to go, I''ll follow you!" Jiang Fang said to the captain half jokingly and half seriously.


    If the captain really has such an idea, Jiang Fang feels that he is really likely to join.


    It''s just a pity that although the captain was excited, he didn''t really want to dig.


    "Hey, what do you think? Mining needs professional skills. What are we doing? Boat runners! Boat runners are at ease. Mining is not our job." the captain shook his head with a little pity. In fact, he did ask about relevant matters, but the professional skills required for mining persuaded him to retreat.


    And more importantly, it is a sense of responsibility.


    The captain patted the reluctant and regretful scallop on his face, smiled at him and said, "young man, look open, you know we are also very important! They can safely open a mine here, but we rely on us to deliver supplies to them and transport the ore they dug out!


    If it weren''t for us, they wouldn''t get supplies here, and the excavated ore couldn''t be transported away, but they couldn''t do anything! So don''t think our work is unimportant. Everyone is making contributions to national construction and doing their own work! "

 Chapter 760

    Lao Hu and his companions came out of the mine and looked up at the sky. It was getting dark at dusk.


    "Lao Hu, how much did we dig today?" a companion walked up to Lao Hu and asked him about today''s work results.


    Not all of their dozen men went down to the mine. Only eleven people really worked underground, and three people were responsible for handling the ore they dug up.


    "I have to ask them, but they should have dug more than 100 tons today?" old Hu shook his head, and he could only estimate the approximate quantity.


    Before the disaster, small iron mines of this scale contracted by them could dig about 20-50 tons of ore a day.


    While Lao Hu and his team have greatly improved their production efficiency by relying on the drill bit on the industrial ship and the mining exoskeleton provided by the state.


    Digging out more than 100 tons of ore a day is not an exaggeration.


    "The standard set by the state for us is to dig 100 tons a day, and the extra is our own. It seems that this period of time has not been in vain!" another man said happily with a happy smile, and he did not forget to ask Lao Hu: "Lao Hu, what do you say we should exchange these minerals for? How about we change a living cabin? The cabin on the ship is still too small, and the family is still a little cramped to live together."


    "What kind of living quarters do you want? If I say, just change a new set of mining equipment. The mining area we contracted is still very large. We can open another sub mine and dig more is serious!" another person obviously has different opinions. He hopes to have more equipment, dig more mines and earn more income.


    This is a very simple idea, which can be called an idea, but Lao Hu shook his head.


    "I''ve thought about it. This month, I''ll find the state to change an ecological greenhouse to let women grow some vegetables, melons and fruits and improve the food for the children. It''s all when they grow up. It''s no good not to eat better." Lao Hu''s idea is simpler, but also more far sighted: "Don''t we work so hard just to make life better for our wife and children? And I asked Xiao Tang. He said that the reserves of this mining area are limited and the geological structure is not very stable. If we dig too fast, the mountain will collapse."


    When Lao Hu said this, several people stopped talking and nodded their heads in agreement.


    After all, everyone did come out to work for his wife and children. As for the fact that the mine can''t dig more, these old men don''t know very well. Among them, only Lao Hu had worked as a miner before, and the Xiao Tang they mentioned was the only one of them who studied geological exploration, and it was the confidence that they dared to contract the mine.


    It was Xiao Tanghua who studied the distribution of ore veins in the mine and told them how to dig more ore, so that they could dig more than 100 tons of ore a day.


    Otherwise, even if they have mining equipment provided by the state, they can dig 80 or 90 tons a day, which is the limit. The standard of 100 tons requires women to go to the mine to help.


    So when Xiao Tang said we couldn''t dig more, everyone had no opinion.


    As for Lao Hu''s need to exchange minerals for greenhouses instead of living quarters, everyone can understand that it is really important to let the children eat better and improve their food.


    They now live on the industrial ship. Although the cabin is a little narrow, everyone lives a little crowded, and life is not very convenient, they can always live. Moreover, the thermal insulation and heating effect of the industrial ship is good, and there is no uncomfortable place.


    If they want a cabin, they just want to live better.


    But to tell the truth, Lao Hu himself really wants the living cabin provided by the state, because it really looks very comfortable.


    The so-called residential cabin adopts a comprehensive design similar to the trap house and container house. A residential cabin is ten meters long and six meters wide. It is divided into upper and lower floors with complete functions. It is completely an integrated house, which can accommodate 3-5 people.


    Lao Hu and his group can exchange about ten living quarters, which is enough for everyone to live in. After all, several single boys can squeeze together.


    Apart from the part extracted by the state, the rest of the ore dug by Lao Hu can be exchanged for a ton of points, while a living cabin needs 100 points, and the luxury version of the living cabin will cost 20 points.


    For Lao Hu and his family, it''s not that they can''t afford to change one set for each person. It''s basically enough to save for two months.


    However, the ecological greenhouse Lao hu wants to change is much more expensive. A greenhouse with 500 points can grow fruits and vegetables. Not to mention, it can also use water tanks and breeding boxes to raise fish and poultry to meet the food needs of about 50 people.


    Only the ecological greenhouse needs additional heating and power supply. They can''t afford an ecological greenhouse by relying on the equipment on the industrial ship. They have to spend more points to exchange for supporting equipment.


    In fact, the heating and power supply equipment were also included in their plan. We had gathered together to discuss and set rules before.


    But now that you have some points in your hand, you can live a good life. You can''t help but have some new ideas and think better.


    This is understandable. After all, a group of people put a safe life in the shelter. However, when they came out to contract the mine, they wanted to live a better life by their own efforts.


    Now that the good days are near, everyone naturally hopes to improve their living conditions. There''s nothing to say, including Lao Hu himself. In fact, he thinks more.


    The party returned to the industrial ship, took off their mining exoskeleton and dusty protective clothing, and then entered the living area of the ship and returned to their cabins.


    It has to be said that mining exoskeleton and protective clothing are a great gospel for miners who need underground operation.


    If it had been put before, I''m afraid the first thing they did when they went up to the well would have been to take a bath and wash away the dust and slag.


    Unlike now, as long as you take off your protective clothing, you are basically clean. Simply wash your face, you can eat with your family.


    The men who returned to their cabins sat down at the table. The women had already prepared meals for them. The family ate dinner happily. Although it was only a simple meal, it was a happy taste for men who had worked hard all day to have dinner with their wives and children.


    The father asked the child about today''s homework, and the wife told her husband about the triviality of the day, which was also full of life satisfaction and warmth.

 Chapter 761

    Compared with the prosperity in China and the better and better life of ordinary people, Europe is not so happy.


    Because of different social forms, the lives of high-level bureaucrats and rich people in Europe do not have much impact. They were ready long before the disaster.


    These people have money and power to ensure that they can still get good living conditions even in the end of the disaster.


    Of course, some of them felt that Europe was not so safe, so they went to the Federation in advance and prepared everything there.


    Originally, in their vision, the Federation, as the most powerful country of blue star, should be enough to ensure their safety and enable them to enjoy a luxurious life even at the end of the world.


    But they did not expect that the impact point of the meteorite happened to be in the Federation, and the eruption of Yellowstone volcano directly buried the whole Federation.


    But in Europe, most people live well because they have not been impacted by meteorites.


    Although this man lives well and is limited to the dignitaries who have been prepared before the disaster, the people at the bottom can only struggle with cold and hunger.


    Although it is said that before the disaster, European countries did not build shelters at any cost, after all, these countries are not as lucky as Lucia and can inherit the legacy from a superpower as compared with countries with strong mobilization capacity such as Yanguo.


    Even in the Cold War era, European countries have built some underground air raid shelters and other facilities, but over time, these facilities have long ceased to exist with the end of the cold war.


    The vast majority of European people are in a state of being abandoned by high-level dignitaries and struggling to survive in the city.


    Fortunately, as the initial disaster passed, the top leaders of European countries still understood that the bottom people were indispensable if they wanted to continue to rule the country.


    Moreover, as the high-level leaders who rule a country, they are not really short-sighted to the point of completely giving up their own people. No matter before the disaster, they do not have the ability to manage it.


    Therefore, after the situation was stable, the top leaders of various countries began to gradually relieve the bottom people of various countries and re count and manage them as valuable human resources to rebuild cities.


    At this time, although everyone''s life was still very hard, some ordinary people who were unable to fight, smash and rob survived by working for the official in exchange for food.


    Just as the invasion of alien creatures began, these ordinary days became very difficult and difficult, even in the apocalyptic environment after this disaster.


    Officials of all countries must transport a large number of materials to the front line to resist the invasion of alien organisms, mobilize the troops originally used to maintain urban security to the front line, and forcibly recruit strong labor from the ordinary people to supplement their forces.


    This also led to the city''s originally slightly improved security environment suddenly fell to the bottom.


    Although some people with ulterior motives knew that there was a war ahead, they still couldn''t restrain their mind. They began to buy zero yuan, even established their own forces, and began to squeeze and enslave ordinary people who were unable to fight, smash and rob.


    Although the officials of all countries know this and send the remaining troops to suppress it, they have limited manpower and are stretched everywhere. They can only press the gourd and pick up the ladle again. They are tired, but they can only make a drop in the bucket.


    The factories and mines controlled by various countries are good, and some major cities can also have relatively good public security in some areas to accommodate ordinary people.


    But in addition, in some small cities, national officials have lost control of the city, which has become a stronghold of local forces.


    They do not directly resist the authorities of various countries. On the surface, they still belong to the official jurisdiction of various countries, and even hand over materials, but they also show a posture of local separatism.


    This not only gives national officials a headache, but also makes the life of the people at the bottom more difficult.


    These local forces are not going to be friendly and polite. For the bottom people ruled by them, they have been squeezed and directly enslaved them as slaves.


    In such a cold and dark environment, the vast majority of these people at the bottom lack food and clothing to keep out the cold, and even have no fuel for heating. They can only struggle hard. Every day, people are frozen to death because of cold and hunger.


    Among them, some local forces may have some foresight and brains. They should be a little better for the people at the bottom, so that they can have some food and a place to live without freezing to death.


    However, the vast majority of local forces only care about making themselves comfortable, do not care about the life and death of these enslaved bottom people, and squeeze and enslave them to death as animals, just to drain their last bit of value.


    Many people are overwhelmed and try to escape from cities controlled by local forces. However, under the pressure of hunger and cold, they lack food, clothing to keep out the cold, and even transportation.


    Escape from the city, waiting for them is still only death.


    It''s just that the difference is to be enslaved to death or frozen to death in the wild with the longing for freedom.


    It can be said that today''s Europe has returned to the dark middle ages. Cities, villages and other places have become independent existence. The so-called state has also reduced to a conceptual title. Although the officials of various countries still control many regions and resources, they are only the strongest of many separatist forces.


    Although countries do not want to see this broken pattern, they are unable to stop it. Most of their military forces have been invested in the battlefield to fight against alien creatures. If they want to suppress domestic division and separatism, they have no way to transfer forces.


    This allows countries to stabilize their existing territory as much as possible and maintain the situation as much as possible.


    However, fortunately, the proliferation of guns in European countries is not as high as that in the Federation. Even if the local separatist forces occupy a place, they do not have much force to dare to resist the regular armies of various countries, so the tax collection is still going on.


    Since we can obtain resources and manpower, the officials of various countries are unable to pay off. In the end, we can only turn a blind eye and keep the situation so.


    But for the Chinese people, this situation is unacceptable.


    On the one hand, the separatist local forces have brought great trouble and trouble to Yanguo''s work of collecting "folk" technologies and materials from European countries. On the other hand, it also makes people worry that they will affect the battle against alien creatures ahead.


    Originally, Yanguo didn''t want to take care of these things. After all, it was the housework of other European countries. However, when a team sent by Yanguo people to exchange materials was robbed and the people were tied up, the nature of the matter became completely different.

 Chapter 762

    Li Yulong curled up and moved his body, trying to sit up from the ground.


    But the posture of hands tied behind their backs makes this most basic action very laborious.


    In addition, Li Yulong has not eaten since he was caught and is locked up in this cellar like place. Now Li Yulong is cold and hungry.


    However, there was no lighting in the cellar where he was held. It seemed that the people who caught him didn''t want to waste valuable fuel or electricity on him, and didn''t even give him the most basic lighting.


    "Hey! Are you still alive?" Li Yulong finally sat up after a long time. He whispered around tentatively.


    He was not the only one arrested, but also two staff members and a locally hired driver.


    As for the two soldiers responsible for protecting them, they were not caught, but fled after resisting and trying to rescue them.


    The all terrain vehicle they came to was robbed by the separatist forces in the small town, which made Li Yulong worry about the goods on the vehicle.


    The things he brought out didn''t matter. They were just a batch of food and living materials, but there were a batch of high-precision parts he had exchanged from another city on the car. He didn''t want an accident with that batch of goods.


    But for now, I''d better care about the others arrested with me and think about how to escape.


    "He''s still alive, but his hands and feet are tied." soon, one of the staff made a voice to show that he was fine.


    The other staff member seems to be in a coma and hasn''t woken up yet.


    As for the hired driver, he quickly said that he had no problem, but his hands and feet were tied up.


    In the face of such a situation, Li Yulong felt some despair. He couldn''t help blaming himself and said, "I was careless and thought these people were good people! As a result, everyone was caught, and I don''t know whether the two soldiers escaped."


    "Don''t worry, I was knocked out at last. I saw them break through." the staff who had woken up said something reassuring to Li Yulong: "we''ll be fine. After they break out, as long as they inform the fleet, someone will rescue us.


    So don''t give up now. Let''s find a way to live first. As long as we support until the rescue arrives, we will be fine. "


    "Well, sure, just these tujiwa dogs, what to take to block the fleet''s land ships and Titans! We will be fine." Li Yulong echoed at this time, but he was still worried about what to do if the people who caught them killed them before the fleet came to save them.


    Li Yulong is not worried about whether the fleet will save them. In fact, no Yanguo people will worry about this problem.


    As long as the country can receive the news of their arrest, it will send forces to actively rescue them.


    This point has been proved by countless examples long before the disaster.


    But it also takes time for the country to save people.


    Although Li Yulong is sure that the state will save them at the first time, what if?


    What if those who catch them outside will kill them before the country comes to save them?


    Maybe someone will open the cellar and shoot at them with a gun the next second?


    Li Yulong doesn''t know what his fate will be. Now he can''t get rid of the shackles of the rope. He can only wait nervously with the hope of the country to save himself and the fear of being torn up.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While Li Yulong was anxiously waiting for rescue, the land frigate, as a rescue escort, had actually taken off and arrived over their small town.


    Although it is a city, it may not be as good as a larger town if it is placed in Yanguo.


    In the bridge of the frigate, the captain was looking at the overlooking map of the small town taken by radar and infrared camera, and confirmed the rescue plan with the staff.


    "I suggest lowering the altitude, shouting at them, asking them to surrender and send them out." a staff officer said his view: "if there is a strong attack, in case the other party tears up the ticket, it will threaten the lives of the hostages."


    However, another staff member objected: "persuasion can''t work. Who knows if these people will resist stubbornly? The longer the confrontation, the more dangerous the hostages will be. What if they threaten us with the safety of the hostages? The contraception will only affect the rescue of the hostages, and when do we need to negotiate with the kidnappers and terrorists?"


    Although the people who occupy the small town are not terrorists, but local separatist forces at most, they are right to say so.


    Both sides'' suggestions are reasonable, and they can be done for escorting Land Cruisers.


    The choice of what to do is in the hands of the captain.


    But after thinking about it, the captain looked at Chen Xin and asked him, "academician Chen, what do you think of this?"


    Because Li Yulong is Chen Xin''s friend, after knowing that the kidnapped person is Li Yulong, Chen Xin also followed the frigate and came to participate in the rescue operation.


    Facing the captain''s inquiry, Chen Xin also glanced at the small town map taken by infrared camera and radar scanning, thought and asked, "can you determine where the arrested person is?"


    "They may be locked up in an underground building, and it''s difficult for us to confirm their location from aerial scanning." the staff officer shook his head and said it couldn''t be done.


    But another staff officer also added: "however, we can send Marines on board to conduct infiltration operations, find out the location of the hostages, and then organize rescue."


    Chen Xin''s eyes lit up when he heard the staff officer say this. He thought for a moment and said to the captain, "in that case, I suggest putting the Titan team I brought into battle, and they launch a frontal attack on the town to attract the attention of the militants, and then the Marines infiltrate to find the hostages for rescue.


    As long as the frontal fire is strong enough so that they don''t have time to think about tearing up tickets, the hostages won''t be in danger, will they? Moreover, our attack is firm enough to let them understand that hostages can''t threaten us. "


    "This plan..." the captain thought about it. It was really a good and feasible plan, so after discussing with several staff officers, he agreed to the plan.


    So the members of the Titan team, who were bored and on standby in the hangar, were excited to sit in their own aircraft. After some servicing, they were ready to go out, and the frigate was gradually reducing its height and landing on the ground.

 Chapter 763

    With the landing of the frigate, five huge figures were put down by crane from the helicopter platform at the tail of the warship.


    Although these Titans have the ability to parachute, they intend to be as light as possible in order to avoid being found by the militants in the city.


    "The longbow is in place, the infrared camera is turned on, the field of vision is good, the target has been confirmed, and the data is uploaded to the command link!" as a white Titan kneels into the shooting position and begins to monitor the town in front of him to provide guidance for the team''s attack, the whole Titan team has also entered the combat position one after another.


    A heavy Titan opened the fixed mechanism of his legs. At the same time, part of the structure contracted and folded to fix himself in the firing position. Then he expanded the firing track of the electromagnetic gun on his shoulder and connected it with the ammunition supply mechanism on his back: "the heavy gun is in place and has launched the siege mode."


    "Siege mode? Do you still need siege mode to fight such a small city?" at this time, a slightly loose voice expressed his dissatisfaction in the command channel of the Titan team: "the sharp knife has reached the attack position. Visually confirm that the other party is only equipped with assault rifles and other light weapons, and a high-speed raid can break through their defense line."


    "There''s nothing wrong with being careful. What if they have a monument that can move for 30 years? Moreover, we feint to attract attention for the special forces to rush into the battle to rescue the hostages. Only by making the momentum bigger can we attract the enemies to us." at this time, another voice also inserted in the command channel: "the Falcon is in place and can launch an air attack."


    Each titan of the Titan team has different combat capabilities. Together, they are an all-round combat team, integrating battlefield investigation, air attack, fire support, battlefield penetration and other combat capabilities. One team is equivalent to the combat capability of a synthetic battalion in the past with the support of land and aviation.


    The military''s positioning of this Titan team is not to take them as ordinary combat units filling the front, but to build them into a sharp knife that can perform a variety of combat tasks and be invincible on the battlefield, which can lay an important force for victory at the most critical moment.


    They can be said to be an attempt of the military to the future war, and also an attempt to use the Titan, a new combat unit, after Chen Xin provided a large number of new weapons for the military.


    It can be said that this team is now the heart of the military, and the army is very precious to them. In addition to allowing them to conduct actual combat exercises on the battlefield of alien creatures at home and sharpen their cooperation ability and combat skills, they will not use them.


    This time, if it was not for the protection of Chen Xin, the military would be reluctant to put such an absolutely elite experimental force into Europe.


    However, since such a team has been placed in Europe, there is now another opportunity for them to carry out combat missions. Naturally, the military will not miss such an opportunity. I hope to test how much this force can play in attacking a town and carrying out anti-terrorism operations.


    After all, so far, the combat missions performed by this team are only hammering alien creatures on the battlefield. They belong to the output of standing piles in the fortress squatting on the defense line. It is difficult to test how strong their actual combat ability is.


    However, with the combat capability of this team, it is really a little overqualified to attack such a small city that does not even count as a military target.


    In particular, they also have a land frigate as support. If it is not for the rescue of hostages, I am afraid that heavy artillery will launch a siege mode. After one round of shelling and combined with the air attack of falcons, the whole town will have to be razed by them. The other three Titans only need to go to the autopsy.


    "Come on, don''t be poor. This is our first combat mission to fight against extraterrestrial creatures. Be serious!" the fifth Titan finally said. It is also the captain of the team, a Titan specialized in electronic warfare and command operations. At this time, it is responsible for communication nodes and electronic suppression, and providing support to the special forces that have penetrated into the small city.


    "I see, captain." even the most expressive knife closed his mouth at this time.


    "Remember, our task is to feint. We need to attract the enemy''s attention. Don''t attack hard and break them." the captain is very satisfied with the silence of the team members in the communication channel at this time. Although there is electronic suppression, it doesn''t matter if they chat in the communication channel, but according to the combat regulations, they should keep the communication silent as much as possible.


    "That''s to stop fighting? But with our firepower, even if we stop it, these armed elements with only light weapons will be crushed?" the sharp knife asked slightly dissatisfied at this time.


    This is not too much. The small town in front of us is really just an ordinary small town.


    Although some barricades have been built because of the snow and being occupied by armed elements, this defensive building built of broken bricks, sandbags and snow may be OK to deal with the police or light infantry, but it is as fragile as a toy house built of waffles in the face of the Titan team with heavy firepower.


    Even if the heavy artillery does not use its own electromagnetic gun that can launch 75mm high explosive howitzer, only the 12.7mm large caliber rotary tube machine gun equipped with sharp knife is enough to wipe out these fragile defenses.


    "Otherwise, why should we do this task? If there is no difficulty, let the Marine Corps on the marine ship do it?" the captain''s tone was also a little harsh at this time, because the task is really no difficulty. The only thing they need to worry about is that they will break the opposite side in another round: "Academician Chen is watching from above! If anyone performs badly and messes up the task, don''t drive the Titan in the future. Return the body to academician Chen and go back and drive the armored car!"


    Hearing what the captain said, the sharp knife with the most desire for performance has become the one with the most serious preparation.


    After all, having a strong desire for expression also means that sharp knife also has a strong self-esteem. Sharp knife is still very proud of his identity as a special Titan driver, which is what he is most proud of.


    If you are fired for screwing up the mission and go back to the original army to drive tanks and armored vehicles, you will lose your face and die.


    Others think the same. No one wants to be thrown back to the original army, which is the biggest shame for a soldier.


    So after the captain said this, everyone took out 120% of the seriousness and investment and was ready for the battle.


    "Heavy artillery, three rounds of artillery, knock down the marked barricade! Block the street with a sharp knife! Long bow, the fire point is your job! Falcons block the enemy''s reinforcement!" the captain assigned the task. When he received the signal from the special forces, he immediately shouted: "attack!"

 Chapter 764

    "Dong!" with a dull noise, Li Yulong, who had closed his eyes to rest because of the darkness, was awakened.


    He opened his eyes and listened carefully, trying to judge what had just made the sound.


    "Is this...?!" the same kidnapped staff also heard the sound and showed some surprise and uncertainty.


    "What''s the matter? What''s the sound?" Li Yulong noticed the abnormality of the staff. Although he couldn''t see his expression, he could also hear the surprise in his tone.


    The staff hesitated, but still explained to Li Yulong indefinitely: "it sounds like an explosion. I heard this sound on the aircraft carrier before. Did the fleet send someone to save us?"


    Just as they were talking, two more muffled sounds came.


    Because they were locked underground, they couldn''t really hear it, but the dull sound that could be introduced into the basement was obviously a big sound.


    "Listen, it''s an explosion! Someone must have come to save us! We''re saved!" the staff got excited. He twisted his body excitedly and wanted to stand up and listen more clearly.


    But his hands and feet were tied, so that he could only wriggle on the ground. After tossing for a long time, he just moved to the door and put his ears close to the door.


    At this time, Li Yulong also looked at the staff with great concern. Although he could not see in the dark, Li Yulong could still judge the position of the other party through his voice.


    At this time, he was also excited and looked forward to it, hoping that someone would really save them.


    Except for the three dull sounds at the beginning, there was no sound from then on. The quiet environment made Li Yulong''s heart sink to the bottom of the valley.


    On the contrary, the staff lying at the door was still expecting. He could vaguely hear some voices. Someone outside was scolding something in German.


    This made him very curious about what happened outside and why there was no explosion.


    In addition to these, what he cares about most is when the people who came to rescue them can find them and rescue them.


    As for those who did not come to rescue them, or there would be no one to save them, it was not considered at all.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "Team a suppresses the enemy! Team B searches for hostages!" at this time, on the ground, the infiltrating special forces have captured a building. They are divided into two groups. One group is blocking the return of armed elements, and the other group enters the building to search for the kidnapped hostages.


    Before, they caught two people alive in the process of infiltrating into the city. After some torture, they determined that the hostages were locked underground of the building, so they contacted the Titan team outside the city to launch an attack. After attracting most of the forces of the militants, they captured the building.


    In the view of the commander of the special forces, the task is really not difficult. Even without the assistance of the Titan team outside the city, they can complete the task of rescuing the hostages.


    After all, they are just a group of armed elements without even heavy weapons. To put it better, they are called separatist forces. To put it worse, they are just a group of bandits and robbers. It is impossible to resist special forces equipped with various advanced equipment, including military exoskeletons.


    However, since the above has provided support, the commander is certainly not going to say not to use it.


    At least under the control of the Titan team, the return force of the militants is very limited, and they can suppress it easily.


    For this group of militants, in the commander''s view, they are already candles in the wind.


    As long as the hostages are rescued, whether they attack, or the Titan team outside the city enters the city, or it is easier to clean up by the land frigate, they can easily crush these bold militants.


    The only difference may be to take into account the image and the long-standing tradition of the inflammatory army, so as to reduce killings and casualties as much as possible.


    It''s just that these armed elements are really bold. The end of armed elements who dare to kidnap Yanguo people is never very good.


    In the past, even if the soldiers of Yanguo abided by military discipline and would not do anything to them, there would be other forces that wanted to please Yanguo to do it as a favor to please Yanguo.


    But now... The commander aimed at a returning militant through the red dot sight, knocked him down with one shot, and then sentenced the terrorists to death in his heart.


    Whenever it comes to Yanguo, the safety of people''s lives and property has always been the first consideration of the state. Threatening the safety of people''s lives and property is an enemy of the whole Yanguo.


    As soldiers of the burning country, the only thing they have to do is destroy the enemy.


    Because a team of people went down to search, they soon found the kidnapped Li Yulong, two staff members and a locally hired driver in the basement of the building and rescued them.


    "The hostages have been successfully rescued and are evacuating. Please ask for fire cover!" seeing that the hostages have been rescued, the commander did not waste time. While reporting to the superior, he also commanded his soldiers to fight and retreat towards the scheduled evacuation site.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "The hostages have been rescued successfully! No casualties!" the messenger quickly informed everyone of the good news in the bridge of the frigate.


    "Great! Order the special forces to protect the hostages and evacuate safely, and the Titan team will cover them. Make sure the hostages are safe." the captain quickly gave the order, and his face also showed a smile.


    With the order, the staff on one side also hurriedly arranged a helicopter to pick up the special forces. They have completed the task. Next, as long as they pick up the hostages, they will successfully complete the rescue task.


    However, at this time, Chen Xin suddenly said, "let the Titan team attack, and the special forces will escort the hostages to evacuate and help to eliminate the militants in this city."


    "Academician Chen, what''s this for?" the captain and several staff members looked at Chen Xin in some confusion and didn''t understand why he said so.


    Facing the doubts of the captain and several staff officers, Chen Xin explained: "the superior agreed to join the Titan team in order to test their combat effectiveness through actual combat. Just now it was just a feint and delaying the enemy. Now it''s time for them to give full play to their real strength."


    Hearing what Chen Xin said, the captain reacted. The military agreed to join the Titan team, but in order to test how much role they can play in the conventional battlefield.


    Now they have only demonstrated their basic firepower suppression ability, and the real cooperative combat ability has not been shown. It is also due that Chen Xin ordered the attack and let them give full play to their combat effectiveness.


    After all, this is actual combat, and there is no better test project than this.


    Thinking of this, the captain also nodded and gave an order: "the Titan team attacked. After the special forces sent away the hostages, they assisted the Titan team to eliminate the militants in the city."

 Chapter 765

    "At present, the security environment in Europe is quite bad. If you can, I suggest negotiating with the European side and let us send troops to clean up the separatist forces in their backyard. Their existence has seriously affected the front-line operations and our work." when Li Yulong was brought to Chen Xin, he was having a video conversation with the top level in China, While reporting on the rescue operation, Chen Xin also put forward his own views.


    However, the high-level leaders obviously have deep concerns about sending troops to interfere in the internal affairs of other countries. Even under this situation, sending troops to help European countries stabilize domestic order is the best practice, but the high-level leaders are obviously not willing to do so.


    "China has always adhered to the five principles of peaceful coexistence, and we have no right to interfere in the internal affairs of other countries." of course, leaders are very excited about Chen Xin''s suggestions, but Yanguo''s long-standing principles still need to be adhered to.


    Chen Xin is naturally not qualified to comment on the leadership''s attitude, but he persuaded: "but now the chaos in Europe is not just their own public security problem. These armed separatist forces also seriously affect the ability of countries to mobilize resources and manpower, and also have a great impact on the European defense line.


    According to the information we have collected, these armed separatist forces have boldly attacked the transport vehicles transporting supplies to the front battlefield. European countries are also tired and unable to suppress these armed separatist forces. If the situation worsens, the European defense line will lose its power to resist the invasion of alien organisms, which is very unfavorable to our country. "


    "That''s true, but interfering in the internal affairs of other countries violates China''s long-standing diplomatic principles." Chen Xin said that the senior leaders are naturally clear, but obviously they have more concerns: "We''ll talk about this later. In a word, even if we really want to enter European countries to help them maintain law and order, the high level also needs more discussion. This is not an easy decision to make, academician Chen. I hope you can understand this."


    In the face of the leader''s attitude, Chen Xin can only nod and say, "I understand that the more this time, the more we can''t mess around, but I still hope that the current situation in Europe can be effectively controlled, not worsened."


    "Of course, it''s related to the life and death of the whole Europe, so we have to act cautiously." senior leaders nodded slightly when Chen Xin said so, and then ended the call.


    Noting that Chen Xin had finished talking with senior leaders, Li Yulong came forward and said hello to Chen Xin: "brother Chen, thank you for saving me!"


    "You''ve worked hard, haven''t you been hurt?" Chen Xin looked at Li Yulong in front of him, just patted him on the shoulder, looked up and down, and said when he was all right: "if something happens to you, I really can''t explain to your father."


    "It''s all right. You saved us before they could do anything to us." although Li Yulong was slightly shocked by a kidnapping, he quickly smiled and said to Chen Xin that he was all right.


    Chen Xin originally wanted to say something to Li Yulong, but the bridge was obviously not a place to talk, so after confirming that Li Yulong was okay, Chen Xin asked someone to take him to rest.


    After Li Yulong left the bridge, the captain also reported to Chen Xinhui: "academician Chen, Titan team and special forces have cleared the militants in this small city. They asked for instructions on what to do next. There are many innocent civilians in the city. They don''t look very good."


    "Civilians? This is a hot potato." Chen Xin shook his head. It''s hard to deal with this matter.


    He did not ask what the status of the civilians was now. He wanted to know how miserable the civilians enslaved by a group of armed elements should be.


    In accordance with humanitarian principles, they should carry out relief, but this is in the territory of other countries. The army of inflammatory countries should not do this.


    If it had been before, Chen Xin might have let the fleet carry out relief regardless, but now after listening to the words of the leader, Chen Xin also knows that some principles that should be observed should continue to be observed.


    So after thinking about it, he said, "inform the local authorities, let them send someone to take over the city, let the special forces and Titan team maintain law and order temporarily, and retreat when the local officials arrive."


    When the captain heard what Chen Xin said, he had no objection. After nodding to show understanding, he went to convey the order.


    After receiving the order, the special forces began to maintain law and order in the small town, and organized some local people to clean up the battlefield.


    Just now they played too fast when they cooperated with the Titan team to clean up the militants. Most of the militants are now lying on the ground without breathing, so someone needs to carry them away.


    The people in the city are very cooperative. After all, these militants didn''t do anything good in the city before. Instead, they tossed them miserably.


    Therefore, the local people are very happy to see these militants cleaned up.


    They not only organized people to clean up the bodies, but also sent some people to ask the special forces if they had to do anything else, and even organized some girls for emergencies.


    For such things, the commander of the special forces can''t really cry or laugh. Although he can understand the local people''s mood, fear and flattery after suffering torture and oppression, it is not only against the military discipline of the country, but also against their principles of life.


    So he sternly rejected the kindness of the local people and asked them to take those girls home. It seemed that the local people were worried about gain and loss. The commander just asked them to help prepare some hot water.


    After all, at this time, if they show that they have no requirements for these people, it is likely to aggravate their fear and ask them to help do something, which can help calm people''s hearts.


    As for asking the local people to prepare food, not to mention the tradition of soldiers in Yanguo, they don''t take a needle from the masses. Just looking at these yellow faced and skinny locals, we know that they are in a state of hunger and cold under the oppression of armed elements. Where can we provide them with any food.


    However, several special forces found the warehouse of the militants while searching for whether there were any remains of the militants. They asked the local people to move out the grain stored in it and let them divide it.


    Looking at the happy look of the local people who were given the food, and the practice of holding the food and eager to gnaw and hurry home to hide, these special forces seem to understand how their ancestors won the popular will of the people.

 Chapter 766

    After that, the local officials came to the receiving city and the civilians did not set off any waves. Except that the troops who came to the receiving city saw the set of exoskeletons on the special forces of Yanguo and the envy, jealousy and hatred generated by the special aircraft of Titan team with different shapes, the whole handover process was quite smooth and smooth.


    However, this incident still caused a lot of waves. After all, Yanguo directly used force in Germany this time, captured a city and wiped out an armed force.


    This was absolutely unimaginable in the past. After all, Germany is also a sovereign country with its own army and territorial sovereignty. In this way, it is undoubtedly a slap in the face for another country to use force in its own country and capture a city.


    But in the current situation, whether it is Germany or other European countries, the first thing they think of is not to get back their face.


    Of course, face is to be found, but what countries see in this matter is the strong combat effectiveness and rapid response ability of the Chinese army.


    The Yanguo people were kidnapped. It took them less than five hours to receive the distress signal, set sail the frigate, and then the Yanguo special forces to clear up the militants and capture the city.


    Of course, there is a relationship between the attack without hesitation of the Yanguo army and the large gap between the armed elements and the Yanguo special forces in terms of force. However, in addition to the powerful equipment gradually obtained by the European armies such as exoskeletons and Titans, the land ships that the Yanguo people can quickly put their troops into the battlefield undoubtedly make all countries jealous.


    If they also have land ships and can form a rapid response force to maintain law and order in their own country, they will not worsen the situation in their respective countries to this extent.


    But for land-based ships, Yanguo will not let go anyway.


    Therefore, after several negotiations, European countries have not achieved their goals, and all countries can only put out their idea of getting land ships.


    However, in addition, all countries are also aware of the deterioration of their own public security, so they took a circuitous way and reached a new agreement with the country.


    "China will send a brigade to Europe, and companies will carry small land ships as rapid response forces to assist European countries in maintaining law and order." senior military officials briefed Chen Xin on the latest agreement reached between China and European countries.


    Asked about the specific content of the agreement, Chen Xin was somewhat surprised: "those Europeans will allow us to send troops into their country?"


    "In fact, they have long wanted us to send troops, but they have not been able to dispatch too many troops in China. Before, they only sent the infantry regiment of the European aid fleet. Now the troops of this brigade are still composed of reserves, and their equipment needs your European side to prepare." the top military level explained to Chen Xin, Although reserve troops have long been used in China, it is the first time that reserve troops have been sent abroad to fight, and the military can only say that it is a new attempt.


    But fortunately, although it is a reserve force, a considerable number of them are recalled veterans, and the overall combat effectiveness of the force is guaranteed.


    But now there are no spare resources to arm them, so we have to load them on cargo land ships and send them to Europe, where Chen Xin will arm them.


    "Academician Chen, you don''t have to worry about equipment. China has negotiated with the European side, and they will provide a batch of resources to produce equipment and land ships for these troops." the top military officials continued to explain this matter to Chen Xin. After all, there are too many places in which Chen Xin needs to participate: "The European demand is to split the brigade into companies, and then they will send the same troops to act with us and take small land ships to maintain regional law and order.


    For European countries, there is no way for them to make their troops move quickly in this weather, so they can only do so. "


    Hearing this, Chen Xin couldn''t help but frown slightly. The Europeans made a loud calculation and asked Yanguo to help maintain law and order and rub Yanguo''s equipment. This is really a very favorable plan for them.


    However, Chen Xin is not opposed to this plan. After all, the situation in Europe is a mess. His original intention is to send a force to maintain law and order. Now that an agreement has been reached with Europe, he is naturally happy to see its success.


    "What about the equipment of these Europeans? We won''t be responsible, will we? Or do they intend to use their own equipment?" Chen Xin asked the senior military officials. There is no problem for their own army to equip, but the European army must ask clearly.


    Although the European aid fleet is now providing equipment for European countries, it is very clear that European countries use resources to order from the European aid fleet, not for nothing.


    "Like the brigade we sent, their equipment is uniformly provided by the European aid fleet, but don''t worry, they will provide additional resources for the production of these equipment." the senior military level dispelled Chen Xin''s doubts and explained: "In fact, European countries plan to directly arm a force familiar with the set of equipment we provide them in this way. After obtaining the equipment, they can use security warfare to quickly form combat effectiveness, so that they can soon get a force with good combat effectiveness.


    After that, they will send this force to the front line of defense to rotate with the troops on the front line of defense. After replenishing their troops, the rotated troops will continue to be dispersed everywhere in this way to cooperate with our troops in the task of maintaining law and order, and continue to change their clothes at the same time.


    Such repeated rotation, in order to deliver enough troops equipped with new weapons for the front line, we have to say that the Europeans'' plan is really good, that is, arming the troops, strengthening the combat effectiveness of the troops, and withdrawing the excessively worn troops in front for rotation. It can be said that they kill multiple birds with one stone. "


    "Well, this plan is really good. Compared with sending our production equipment directly to the front line and letting them get familiar with our equipment in a short time," Chen Xin appreciated the plan, nodded and said, "as long as they can provide the materials needed for production equipment in time, I have no problem here."


    This plan must be said to be really good. The troops of Yanguo do not rotate, so that more than half of the experienced "veterans" can always be maintained. The European side can also rotate the "recruits" all the time, so that they can quickly get familiar with new equipment, form a battle, and then return to the front line to replace new "recruits", forming a virtuous circle.


    These people will not be idle, maintain law and order, improve the domestic environment and situation of various countries, and undoubtedly strengthen the management of their respective countries.

 Chapter 767

    After the adoption of the resolution on the formation of joint forces to maintain public security in European countries, the European aid fleet began to build new barracks and produce equipment for the upcoming troops.


    The main work of this force is to maintain the declining public security and domestic order of European countries, and make the armies of European countries familiar with their newly acquired equipment, so as to form combat effectiveness against alien creatures. Naturally, it enjoys a high priority in equipment acquisition.


    In fact, European countries have long planned to directly arm an army equipped with new equipment and then send them to the battlefield.


    Previously, due to the problem of production capacity, the equipment they obtained from the European aid fleet were small batches, which could only be transported to the front line piecemeal to supply the most needed troops, not to mention, but also because of insufficient production, they could not change the equipment for a whole force.


    Only a small number of people can be armed first or dispersed as team weapons, and these people equipped with new weapons can be used as reserves and mobile forces to fill or support the front when necessary.


    Although it is not impossible to play a role in this way, it is obvious that such a small-scale change can not maximize the role of new weapons.


    Moreover, this practice, which is similar to putting sugar in well water, also plays little role in improving the overall combat effectiveness.


    After all, only a few people can get new weapons, accounting for a very low proportion of the total number of front-line people, and the vast majority of soldiers are still using their original weapons.


    Originally, European countries also wanted to get more new equipment. It''s best to arm an entire army at once, or even let the defenders on the front line change their clothes at once. However, limited by the production capacity of the industrial base of the European aid fleet, this is just an assumption.


    However, with Chen Xin''s construction of sub bases in Europe, the resources continuously obtained from these sub bases not only meet the production needs of the industrial base, but also greatly improve the production capacity of the industrial base and produce more equipment, which makes it possible to push the plan forward.


    Otherwise, even if countries have passed the resolution to form a joint force, they do not have so much equipment to provide them. They can only wait for the industrial base to squeeze out equipment a little, or hope that Yanguo can transport some equipment from home to Europe to arm this force.


    However, thanks to the good operation of the sub base and the fact that the arsenal of European countries can produce relevant supporting parts after obtaining the production technology and drawings provided by Yanguo, the capacity of the industrial base is quite sufficient, and the newly built production line can operate at full capacity.


    The production of equipment sufficient to arm the troops of a brigade is a month, and this also includes small land ships to be provided to them.


    In terms of design, Chen Xin has learned from the design ideas of domestic small industrial ships and optimized the design based on the mobile base. The interior can accommodate the troops of a company and carry their weapons and equipment and attached vehicles.


    Because this small land ship can fly, it has no function of taking off and landing helicopters, and there is no hangar carrying helicopters. There is only a garage for parking armored vehicles to carry the vehicles allocated by the company.


    Moreover, because it is a small military ship and is used together with Europeans, after careful consideration, Chen Xin removed the greenhouse cabin on the ship, so that this type of land ship needs to rely on external supply input and can not maintain itself for a long time.


    To a large extent, this saves space for small land ships and reduces its volume. After all, after taking away so many functions, small land ships are much smaller than mobile bases and can be called pocket warships.


    After Chen Xin''s discussion with China, the company carried on this small land ship is also determined to be three platoons in a row. The army of Yanguo accounts for two-thirds. Only the European troops who have completed the dressing and adaptability training can be assigned to these small land ships and become the remaining one-third.


    This is mainly to ensure that sufficient manpower can be used to maintain law and order and to ensure the control of Yanguo over land ships.


    After all, at present, China has not opened the technology of land-based ships to European countries. If European countries have any ideas about land-based ships, they can''t forcibly seize the control of land-based ships when the number of people is not dominant.


    On the other hand, according to the original plan of European countries, a brigade will receive equipment, carry out adaptive training, and assist in maintaining law and order in the process. When their training is completed, the whole brigade will be taken away and sent to the front line, and then replace the next brigade from the front line to restart training.


    However, this plan was rejected by the Yanguo side. Instead, it was modified to make one-third of the people receive adaptive training. After completing the adaptive training, they carry out practical training. Those who have passed the practical training will help maintain public security until the next batch of people who have passed the practical training replace them.


    The European plan is undoubtedly to quickly obtain large quantities of troops equipped with new equipment. The training of such a brigade by brigade can indeed quickly complete the dressing and training of a large number of troops, but naturally, the main work of maintaining law and order is transferred to the Japanese army.


    Although it is said that maintaining law and order is the main purpose for the troops of the brigade of Yanguo to be sent to Europe, even so, Yanguo is still unwilling to do everything by themselves. These Europeans just come to get jealous.


    Therefore, they revised the training plan. Although according to the revised plan, the production of troops equipped with new equipment has changed from a brigade every three months to a regiment every month, although the overall training speed has not changed, it is more sustainable.


    Moreover, this way can also better perform the task of maintaining law and order, and enable these troops with new equipment to gain more practical experience through the battle of maintaining law and order.


    Although the main components of these troops are veterans who have been removed from the front line for repair, the configuration of exoskeleton and electromagnetic rifle is completely new, and the combat effectiveness has also changed a little. Even these veterans must re carry out adaptive learning and correct their originally established combat habits.


    Although the European side did not like the plan of Yanguo very much, after some discussion and discussion, they were finally persuaded to agree to the plan.


    The first batch of troops to receive training were transferred from home by European countries, quickly completed the formation, and then sent to the newly built barracks in Yanguo.

 Chapter 768

    After getting off the transport plane, Bob carried his luggage and looked curiously at the training camp where he needed to stay for two months.


    This is a military camp composed of a large number of shelter buildings. It looks like the planning of a field military camp, but structurally, in addition to a field runway for aircraft landing, there is also a large parking apron for land ships.


    At this time, a large number of small land ships assigned to this force are docked here, and some soldiers of Yanguo are around these land ships. I don''t know what they are doing.


    In addition, there are many large buildings similar to the hangar in the military camp. Many soldiers in European uniforms like Bob are getting off the plane carrying them here and being sent into these buildings.


    Bob was no exception. Following the crowd, he also walked into a building that also looked like an aircraft hangar.


    The entrance of the building seems to be for cold protection and thermal insulation. A channel made of thermal insulation material is specially built. Bob is allowed to enter after a simple inspection.


    "What are they checking for? Malnutrition?" a soldier behind Bob asked Bob. He came from another army. After meeting Bob on the plane, they talked quite speculatively, so they walked together after getting off the plane.


    The malnutrition in his mouth is not a joke. In fact, although the soldiers sent here are in good condition, they are limited to the increasing lack of supplies before. Everyone receives more and less, and they are somewhat malnourished. Many people even look yellow and skinny.


    For the problem of companions, Bob felt that it was unnecessary to check whether they were malnourished, because one of them could be regarded as malnourished.


    "Maybe it''s epidemic prevention inspection? After all, our group basically came down from the front line. They may be worried about what alien virus we were infected with on the front line." Bob said his speculation, but his eyes couldn''t stop looking at the hangar shaped building.


    There is a large open space inside the building. Instead of parking aircraft, there are sets of exoskeletons, electromagnetic rifles and power armor.


    Bob''s eyes missed seeing the power armor.


    Bob''s company received some supplies, including several sets of power armor, when the Yanguo supply ship transported supplies to the defense line.


    Bob got the right to use power armor because of his good performance. He always wore that set of power armor in subsequent battles, played a great role and performed very well.


    Even once an alien creature broke through the line of defense and rushed into the trench. It was also Bob who killed the alien creature and prevented it from damaging the line of defense by improving the combat power provided by the power armor.


    Only in the process, Bob was seriously injured and had to be sent to the rear hospital for treatment, and his power armor was damaged during the battle.


    Bob was still sorry for his damaged power armor. At the same time, he also looked forward to completing the treatment as soon as possible and returning to the army. He asked his superior if the power armor could be repaired and whether he could put on the power armor again.


    However, with the deployment of European countries to form a joint force, Bob did not return to his original force, but was sent here together with other healed wounded soldiers to become the grass-roots officer of the newly formed joint force.


    After all, although the joint force is a new barracks in a sense, it is obviously impossible for European countries to really recruit a large number of recruits to receive the training of Chinese people and new equipment. Their way is to transfer a group of cured veterans from the rear hospital as grass-roots officers to build the officer system of the joint force.


    This is also a common practice of European countries in the past. When it is not necessary to maintain a large-scale army, they usually maintain the number of a force by retaining the military corps. When it is necessary to use this force, they will call enough recruits or demobilized veterans to fill in, and quickly form a complete force with the support of the military corps and veterans.


    This can also be used for the formation of troops in wartime. After all, if the intensity of the war ahead is too high, many troops will be scattered, and most wounded soldiers may not be able to return to their original troops in time because of the different time of recovery.


    At this time, in order to avoid waste, they are usually organized into a new force.


    As a member of the new army, Bob didn''t quite understand what the army was doing at this time, but seeing the equipment placed on the shelves in the hangar, Bob guessed that they might be trained in how to use these equipment.


    "It seems that our regiment is going to completely change the equipment of Yanguo people?" Bob''s companion asked him in surprise. After all, these exoskeletons and electromagnetic rifles in front of him can be seen as Yanguo people''s equipment.


    "It looks as like as two peas," Bob looked at a power armour, which was exactly the same as the one he had worn before. This made Bob expect to wear it again.


    "Wow, it seems that you''ve worn it before, so you should have a chance, but I don''t think they put much power armor. Maybe only some people can wear it." Bob''s companion looked around and found that the number of power armor was really small.


    Just as they chattered and talked about these equipment in groups, a group of soldiers from the inflammatory country came in in neat lines.


    With them came a group of officers in military uniforms of various countries. Bob noticed that there were English officers among them. According to the rank, it was a captain.


    However, in this group of officers, it seems that the leader is a major of Yanguo.


    Bob didn''t have any idea about it. After the officers and soldiers of Yanguo came, he quickly stood up with others to welcome the officers.


    "I think many of you may not know what you''re doing here." the opening is the major Yanguo, who speaks good English to Bob, although with a little colonial accent and more federal English: "Here I would like to explain that in view of the current security situation in various countries and the needs of the front line against alien organisms, various countries have established this joint force to maintain order in various countries and be put back into the battlefield after adapting to the new equipment."


    Hearing this, Bob was excited. He knew he had a chance to wear that power armor again.


    The other people nearby are also excited. Who doesn''t like these new equipment? Even if it''s only a second-class exoskeleton, it''s very popular on the battlefield.

 Chapter 769

    "Get out of the car, you pigs!" a loud sergeant was yelling. In front of him, a military car lined up, and the recruits were getting off.


    Like others, in the roar of the sergeant, Elvin jumped out of the car with his luggage and others. While standing in a row shivering in the snow, he also looked around and looked at where he was now.


    Their location should be a playground, where many transport vehicles are parked, and a large number of people like Elvin are gathering here.


    Many lamp posts were erected around. The light of the searchlight made the playground as bright as day. Elvin couldn''t help covering his face with his hands. He hadn''t felt such strong light for a long time.


    Some tall buildings surround the playground, but perhaps the light of the searchlight is too strong, so that these buildings are basically shrouded in the shadow. They look like a giant beast hiding its body in the dark.


    Amid the sergeant''s roar, Elvin and the others formed a simple line and walked towards one of the buildings.


    When he came near the building, Elvin recognized that it was a huge hangar, which calmed Elvin a lot, and he couldn''t help feeling a little cordial to the building in front of him.


    As a ground crew member of the airline before the disaster, Alvin was still very familiar with the hangar, which greatly reduced his fear of this strange military camp.


    Although the German army was not put into the front line against alien creatures, everyone knew that it would happen sooner or later as the war continued.


    Now, Erwin feels that countries are ready to send the Germans to the front.


    But this is no problem for Elvin.


    Compared with the danger that he might encounter in the battlefield, Elvin thought it was more terrible to starve or freeze to death.


    For this reason, Elvin is one of the few people here who volunteered to join the army.


    Most of the remaining people are basically recruited by countries for compulsory recruitment. In their view, feeding insects on the front line is the most terrible.


    However, for Elvin, as long as he can eat enough to join the army, he doesn''t mind going to the front line to fight alien creatures. Even if he finally dies and feeds alien creatures, at least he can eat enough when he is alive and won''t starve to death.


    Several years have passed since the disaster. In these years, Elvin lost his family and hardly had enough to eat.


    Although he has always worked for the German government in exchange for some food, in today''s environment, if he doesn''t save a little, he is likely to finish this meal and there will be no next meal.


    As a result, after hearing that he could eat enough to join the army, Elvin took the initiative to join the army and was sent to the camp.


    At first, Elvin thought that he might be simply trained, and then sent to the battlefield as cannon fodder.


    Just like the war story his grandfather told him when he was a child.


    During World War II, his grandfather was drafted into the army and sent to Stalingrad, where he survived the worst winter in German history.


    However, the German veteran who lived through World War II died long before the disaster. He failed to withstand disease and aging.


    But as Elvin entered the hangar after passing the health quarantine at the gate of the hangar, he found that he didn''t seem to be coming to be cannon fodder.


    Because in the huge hangar he walked into, many soldiers were being trained. They were equipped with exoskeletons and power armor that Elvin had only seen in science fiction movies and games before, and recruits like him were randomly assigned to classes.


    Seeing this scene, Elvin''s uneasy heart seemed to settle down at once.


    If you can wear exoskeleton or power armor, you can''t consume cannon fodder at will, can you?


    After all, no one would equip cannon fodder with such advanced equipment, would they?


    Unexpectedly, however, Elvin was not assigned to the teams equipped with exoskeleton and power armor, but was brought to a group of people who looked like ground technicians.


    "These are your new recruits who have experience in mechanical maintenance." the sergeant in charge assigned Erwin and the other two recruits to the team, so he continued to assign other recruits.


    This makes Elvin feel a little regretful. Although it is said that the ground service is far more likely to survive than combat soldiers, he still has the impulse to try looking at the handsome exoskeleton and power armor that only appear in science fiction.


    The veteran on one side seemed to see his idea, reached out and patted Erwin on the shoulder, smiled at him and said, "boy, don''t envy us. We are a maintenance class. Their handsome big toys will eventually be sent to us for repair. You have plenty of opportunities if you want to play."


    "Thank you, I see." Elvin responded to the Veterans'' comfort and quickly said hello to the veterans: "Hello, my name is Elvin. I''m from Berlin. I heard you can eat enough here."


    "Ah, another guy who came to join the army to eat enough!" the veterans laughed and showed kindness to Elvin''s reason for joining the army.


    One of the veterans also took out an energy rod from his body and threw it to Elvin. He smiled at him and said, "eat. We can really eat here. In addition, we are ground service. We don''t need to train like them, as long as we can repair these big toys."


    Seeing the energy bar thrown to him, Elvin wanted to put it in his pocket, but felt his hungry stomach. He couldn''t help but unpack the package and put the energy bar into his mouth.


    "Hey, what did you three do before? Have you repaired anything?" the veteran who looked like the leader of their maintenance team asked Elvin and two other recruits.


    After the two recruits next to Elvin looked at each other, one of them said, "I studied car repair. Before the disaster, I opened a repair shop. This is my brother. He learned the same things as me."


    "I used to work on the ground in an airline. After the disaster, the plane couldn''t fly and the company closed down. I had been living in Berlin before." Elvin also chewed the energy bar and introduced himself to several veterans.


    While they are introducing themselves, other teams are doing the same thing, but relatively speaking, the requirements of other teams are obviously much stricter than the ground team.

 Chapter 770

    The two-month training period soon ended. For Elvin, he didn''t seem to have had a few full meals, and only half of the rich Chinese dishes in the canteen were tasted.


    For Bob, these two months have been very solid. In these two months, he was installed in the power armor for training almost every day, and even made him hallucinate once, as if the power armor was a part of his body.


    In fact, not only Bob, but many trained soldiers had similar hallucinations.


    This is mainly because the power armor and exoskeleton provide a strong strength blessing. If worn for a long time, it will give people an illusion that their strength has really improved so much.


    In particular, soldiers wearing power armor may only be able to lift more than 100 kilograms, but after wearing power armor, they can easily lift more than a ton of things. It is easy to have an illusion that their power is increased by 20 times.


    This has led to a large number of non combat attrition before the newly formed joint security maintenance force went to the battlefield.


    Some soldiers who had hallucinations thought that their bodies could reach the output of exoskeleton or power armor, and did the same thing after taking off their equipment, so they strained their muscles and fractured their bones


    As a result, the multinational joint command of the force had to transfer a large number of psychologists to coach and adjust them. At the same time, it also asked the inflammatory forces, which nominally belong to the same force, how to overcome this problem.


    However, it is surprising that there are few such problems in Yanguo. Even though Yanguo is equipped with far more exoskeletons and power armor than European countries and has been equipped for a longer time, few soldiers or civilians will hurt themselves because of illusion.


    Psychologists carefully analyzed it and finally came to a conclusion that people in European countries are more direct and advocate power in character. Therefore, after the great increase of power, self-confidence also soared, resulting in a psychological illusion.


    However, Yanguo people are more introverted. They do not show off their strength, but regard it as a tool. They have a clear understanding from the beginning. Therefore, they rarely have the illusion that the strength of exoskeleton or power armor is part of their own body.


    This result made European countries look at each other, but the problem was finally solved because it was discovered early. The joint security maintenance force finally completed all the two-month training and can perform security maintenance tasks together with the troops of the country.


    Sent out to carry out law and order maintenance work is a combined regiment of two inflammatory countries and a motorized infantry regiment composed of European countries.


    A total of 30 small land ships were assigned to them, and companies were sent to European countries. A new security line was set up behind the front line to maintain order in all countries.


    He Cheng Tuan is a new way of organization in Yanguo, and its model comes from the military reform of division reform brigade and regiment before the disaster.


    As the country with the strongest infantry combat effectiveness on the blue star, Yanguo has gradually abandoned the force formation of the traditional operation mode in the past, and adopted the synthetic force of multi arms joint operation.


    The so-called synthetic force is to group mechanized infantry, tanks, artillery and even missiles into an attack cluster.


    It is not like the traditional formation mode, which is formed by a single arm. When multiple arms are combined, they also need to coordinate and command, which will affect the operation efficiency.


    For example, the brigade sent to Europe this time is a composite brigade, which is composed of one artillery regiment directly under the central government and nine battalions directly under the central government.


    Among the nine battalions directly under the central government, in addition to the Kaixin battalion, the industrial and chemical battalion and the repair battalion, the remaining six battalions are four armored infantry battalions and two tank battalions respectively.


    However, due to the use of new equipment, great changes have taken place in the functions and arms of the force. For example, the armored infantry battalion is now equipped with exoskeletons and no longer takes armored vehicles, but changes to small land ships, and the tank battalion has also replaced tanks with Titans.


    In addition, it is now cooperating with the joint forces composed of European countries, so the United States has also adjusted the formation of troops, the original formation mode has been adjusted, and the troop ratio has been readjusted with the company as the organic system.


    Each small land ship carries a company of troops as combat troops, and they are additionally equipped with driving, medical and repair teams.


    The joint force formed a reinforced platoon of mechanized infantry, which was composed of three classes of soldiers equipped with exoskeleton and one class of soldiers equipped with power armor according to the suggestions given by Yanguo.


    The two platoons in Yanguo are completely different. They add up to a total of six classes. One class is equipped with power armor, one class is equipped with Titans, and the remaining four classes are ordinary soldiers equipped with exoskeletons.


    In this way, on such a land-based ship, there are two classes of power armor as heavy firepower units, while the Titan is responsible for acting as the original tank, and seven infantry teams equipped with exoskeletons will cooperate with the Titan in infantry Tan coordinated operations under the cover of power armor.


    Such a force, coupled with the support of land ships, can be said to have quite strong combat effectiveness.


    It''s more than enough to fight alien invasion on the front line. It''s just overqualified to maintain law and order.


    However, this has also made this force used to maintain law and order play a very strong role.


    With the high mobility of landing ships, although this force was divided into company level combat units, relying on the strong combat effectiveness of company level combat units, they quickly eliminated most separatist forces in European countries and stabilized the domestic security environment of various countries.


    Of course, because of their limited military strength, they can only stabilize most of the main settlements, and there are still some areas beyond their reach.


    After all, although they have strong combat capability, the company level is already the smallest combat unit that can be split. If they are split down, although the troops still have enough combat effectiveness to defeat a separatist force, they can not effectively control an area.


    Therefore, the joint security maintenance force can only regularly clear the areas not under actual control after stabilizing the security in the main areas.


    However, this is not without benefits. At least after this group of joint forces have completed a one month security task and been transferred back to the front line, the new troops will not be unable to accumulate practical combat experience without the enemy.

 Chapter 771

    Nuremberg is a city in southeast Germany. It is located in the small basin along the Pegnitz River in the northwest of Munich and forms a Shuanglian city with the adjacent field.


    It is an important industrial and commercial center in Bavaria. In history, it was famous for toy manufacturing in Europe. Before the disaster, it was a city with a population of more than 500000.


    This is also a city with a long history. It was once famous in history. Although it was not a good reputation, it also led to the severe bombing of the city during World War II.


    At the time of the disaster, the city was not hit hard because of the terrain.


    In addition, it is an important transportation hub in the region, so German officials also give priority to the post disaster reconstruction of the city.


    After the invasion of alien organisms, it has been paid more attention as an important transportation route to transport materials from Germany to the front line of defense. German officials have arranged a brigade here to ensure the smooth material transportation.


    For the brigade stationed here, their days are undoubtedly very comfortable compared with other colleagues.


    Nuremberg is located behind the defense line. Although it is said that occasionally some alien flying units will cross the defense line and attack the rear, they will not have much impact and will be hit by anti-aircraft artillery.


    As a material transfer center, it will obviously not lack material supply.


    Stationed here, we do not need to fight and kill like the troops on the front line, nor do we need to pull out every bit of materials from our teeth and transport them to the front line to support operations like the rear.


    It can be said that they only need to properly express their sense of existence every day to maintain the operation of the city, and they can eat fat.


    I really should have said that, the front is tight and the rear is tight. This army can be said to be full of pride and Jiao here.


    If it were not for this army, which still knows its position is very important. Once it affects the front-line operations, it will lead to the complete collapse of the defense line and the destruction of the whole human world. They are somewhat restrained in their work, and they do maintain the material transfer of Nuremberg after they are full as much as possible, I''m afraid it has already become a local separatist force.


    After all, there is food and drink here, and as an important traffic road, it has important strategic significance since ancient times. Relying on the terrain, the defense here is also very strong, and fully has all the necessary conditions for forming a local separatist power.


    This has led to the army becoming more and more arrogant. In addition to not forming a de facto separatist regime and openly disobeying official orders, they are actually no different from the separatist forces occupying the place.


    Relying on the force in their hands, although they are not called slavery, they are also driving the people of this city to serve them, and the military discipline has long been corrupted.


    Of course, German officials wanted to replace them, but they suffered from not having enough strength to make the army yield. They could only hold their nose and endure their existence, resulting in the loss of at least 10% of all materials passing through Nuremberg.


    However, in the view of the garrison, they have really done what they can call dedication and benevolence. At least they are still doing their duties. They are also restrained in the matter of floating and disappearing, and only get 10%, haven''t they?


    However, for German officials, the existence of this force makes them feel like a lump in their throat. It''s like an old sputum stuck in their throat. They can''t swallow it or spit it out. It has been stemming disgusting people.


    If this army creates a de facto separatist regime and openly resists the official decrees, the German authorities can also directly suppress them and eradicate this cancer.


    However, they did it in a proper way, which made German officials have no suitable reason to completely suppress and eradicate them, so they can only be disgusted.


    After all, now German officials can still maintain their existence, which largely depends on the support of the military. If they lose the strength of the military, German officials obviously can''t even control their capital.


    The army did not openly betray and confront the official, so he was still a member of the German military. In addition, the chief officer of the army was also in charge up and down, and someone spoke for him, which made the German official unable to deal with the army.


    This also makes this army clearly know that the authorities have no way to take them, making them more arrogant and unscrupulous.


    However, with the establishment of the joint security force, the security force jointly established by European countries began to operate, and a large number of separatist forces and armed elements were eradicated, which still made the commander of the force feel a certain threat.


    For the sake of safety, he also warned his men to restrain themselves during this period to avoid hitting the muzzle of the gun. He was beaten to the door by the joint security forces and exterminated as a separatist force.


    Although the force also has a brigade strength, the commander of the force does not think that the force in his hand is capable of fighting the joint security force.


    After all, among the previously lost materials, there were equipment provided by Yanguo, which was enough to make him clearly realize the huge gap in combat power between a soldier equipped with Yanguo equipment and a soldier not equipped with Yanguo equipment.


    Not to mention, he already knew that all the members of the joint security forces had been equipped with Yanguo equipment, and he had never seen such powerful equipment as Titans and land ships.


    Although facing the worries of his subordinates, he confidently said that the land ship was just a target flying in the sky, which could be shot down with anti-aircraft guns.


    But in fact, he clearly knew that if the joint security forces came to attack him, even only one regiment''s strength would be needed to defeat his army. If the two forces were equal, it would be a war of annihilation without doubt.


    In the city, equipped with exoskeleton and power armor, and supported by Titans, the army has too much advantage.


    It was precisely because he knew this that he deliberately asked his men to restrain a little during this period of time.


    Under the guidance of the chief officer, this unit is still relatively sober. It is not out of mind, or because of the current environment, it feels that no one can do anything about itself. It is still obedient and restrained its recent behavior, so as to avoid being approached by the joint security forces.


    After all, although the joint security force was established not long ago, it was enough to prove that it was powerful and terrible to wipe out most of the separatist forces and armed elements in European countries in just one or two months.


    However, whatever they were afraid of, just when the commander of the force was worried that the joint security forces would come to the door, they had appeared over Nuremberg.

 Chapter 772

    On the bridge of the land ship, Chen Xin and the captain listened to the second lieutenant who came to report, and their faces showed an expression of sadness and laughter.


    "Although it was said before the disaster that the German army had become a civil service, and its combat effectiveness had declined sharply, it was not unreasonable to this extent?" Chen Xin shook his head and knocked on the table with his finger joints: "A brigade! It was scared to surrender just because it saw the land ship of the security forces? Is that ridiculous? They deserve to be called soldiers?"


    Different from Chen Xinyi''s expression of destroying Sanguan, although the captain also felt outrageous about the performance of the German army, he still asked the second lieutenant in front of him what was going on.


    After all, he and Chen Xin just came to inspect the logistics support of the front line, not to clean up the local troops. Suddenly, such a garrison surrendered to them, but they were really caught off guard.


    The second lieutenant is a company commander of the joint security maintenance force. His original task was only to serve as Chen Xin''s escort force, take his company''s land ship with Chen Xin''s escort land ship, inspect several important material transfer cities behind the defense line, and be responsible for security work.


    However, no one expected that when the two land ships arrived at the first big city in their inspection trip, the local garrison would collectively surrender because they were frightened by the two land ships.


    This is an incredible thing for the soldiers of Yanguo. In the history of this army, they have not surrendered since the day they were established.


    On the contrary, there are many examples of fighting until the last soldier and the whole army is finished, but still fighting hard and sticking to their positions.


    So when this happened, they really felt incredible.


    But now that things have happened, we still have to deal with them.


    Therefore, when receiving the surrender statement issued by the other party and seeing that the other party concentrated its weapons and fired a white flag, the second lieutenant, as the commander of the company, could only release his own troops to control the city and control the surrendered troops. While figuring out what was going on, he hurried to report the situation to Chen Xin.


    Now when Chen Xin asks, the second lieutenant naturally keeps busy reporting to Chen Xin what he has just found out.


    "So they feel guilty because of their corruption and think we are here to destroy them, so they directly surrendered to us in order to survive?" Chen Xin felt more and more sad after hearing the second lieutenant''s introduction and explanation.


    "That''s right," the second lieutenant nodded.


    "Well, first take prisoners, control the city and maintain law and order. What to do depends on the arrangement." Chen Xin also feels unimaginable. The army has surrendered to him and confessed what they have done. If Chen Xin does not accept their surrender, it will obviously become more troublesome.


    In particular, they now have only two land ships and only one company on hand. If they fight, they may not be able to defeat the garrison, even with the help of two land ships.


    However, Chen Xin also kept an eye and did not let the two land ships land, but let them patrol over the city.


    This can not only serve as a deterrent to the surrendered Garrison and the people in the city, but also make them wonder how many people there are on the two land ships.


    After all, we have to rely only on the strength of one company to receive the surrender of a brigade. This strength is really a little stretched.


    So let the other party not know how many people they have, and at the same time, dispatch a group of crew from the land frigate to assist in receiving prisoners, which is the only way at present.


    The second lieutenant took command and most of the troops on the two land ships were put on the ground.


    In addition to the company led by the second lieutenant, Chen Xin transferred the equivalent of two reinforced platoons from the land frigate, and threw all the power armor and Titans on the two land frigates. In this way, there are almost two companies.


    Coupled with the deterrence of land-based ships, even if the surrendered garrison reacts that there are fewer land-based ships than they expected, they dare not easily explode and stab.


    "Academician Chen, should we ask for help?" the captain looked at Chen Xin and asked him.


    Chen Xin nodded slightly and said to the captain, "of course we need help. Send a help signal to the surrounding security forces and let them send all the land ships. In this way, even if there are no people, relying on the land ship alone is also a deterrent."


    "Yes, I see." the captain answered and hurriedly asked the messenger to send a signal for help.


    At this time, the captain was also a little scratchy. After all, now they only have two land ships. Because they want to deter the ground, they have to be relatively low. Almost all the troops that can be transferred on the two ships have been sent down, resulting in the emptiness of the frigates.


    Under such circumstances, if the soldiers of the brigade below suddenly feel that the land-based ships in the sky are just paper tigers, or see through their reality and become unwilling to surrender, the captain feels that he has no way to protect Chen Xin.


    Fortunately, this area is one of the areas that Germany attaches great importance to at present. Many companies of the joint security maintenance force have been assigned here. After receiving the captain''s request for help, most of them gave certified replies and said they would rush there as soon as possible.


    Chen Xin was relieved to learn that other land ships were coming.


    In this way, they only need to insist until other land ships arrive. As long as other land ships arrive and have enough manpower, even if the following troops turn against the water, Chen Xin can send land ships to suppress them again.


    With this guarantee, Chen Xin studied the map of Bavaria again and thought about how to adjust the material transfer efficiency here.


    However, the work was interrupted before it started: "academician Chen, a total of four land ships have received our help signal, and they can arrive in about half an hour."


    "That''s great. How about the reception of the prisoners below? Nothing''s wrong?" Chen Xin heard that four land ships would arrive, which undoubtedly gave him great self-confidence.


    "At present, our army has received about a battalion of troops, and the political commissar on board is selecting some of the more reliable personnel to form a team to help our people work." the soldier who came to report replied to Chen Xin and said: "The people in the city have known what happened. They are gradually taking to the streets. Everyone looks yellow and skinny. Should we give them relief?"


    Facing this problem, Chen Xin didn''t directly open the warehouse to relieve the victims as he did last time. Instead, he said, "put the food first. When other frigates arrive, let''s talk about how to relieve these victims."

 Chapter 773

    After the arrival of two land ships that received the request for help, Chen Xinli''s reliable troops reached a battalion. Only then did he have enough strength to control the situation in Nuremberg.


    At the beginning, the company that arrived with Chen Xin was first sent to the ground. After collecting the weapons of the surrendered Garrison and taking care of them, they began to organize the citizens of Nuremberg to continue the material transfer to the front line.


    Originally, the garrison was responsible for this part of the work, but now that the Garrison has been taken care of, this part of the work will naturally be handed over to Chen Xin.


    The two companies that subsequently arrived were assigned other tasks by Chen Xin.


    One of the companies is responsible for maintaining law and order throughout Nuremberg. Although a company''s troops are too weak to maintain law and order in a city with hundreds of thousands of people, they have selected some people from the Garrison under custody.


    With the help of the garrison whose weapons were confiscated, they also controlled the security and situation in Nuremberg and adjacent fields.


    After entering Nuremberg, another company called a group of citizens. With the help of these citizens, they began to distribute materials in Nuremberg to relieve the hungry and cold people.


    Seeing that most of the work was finally carried out in an orderly manner, Chen Xin was relieved, and after the subsequent two companies arrived, he went down to the ground with the two companies.


    Walking on the streets of Nuremberg, looking at the people with expectations on their faces pouring towards the material distribution points, Chen Xin couldn''t help shaking his head and said helplessly to the political work cadres beside him: "what do you call this? At least Germany is also a sovereign state. It is also a big and powerful country in Europe. Why can''t even control its own army?


    It''s just that you can''t control the army. It''s a big deal to say that you are weak and arrogant, but the army can be scared to surrender by two land ships. The fighting will is poor to this extent. I really doubt whether they will be deserters on the battlefield. Can they really hold the front line? "


    No wonder Chen Xin felt it. Before, he didn''t know much about the equipment of the garrison in Nuremberg. He thought it was just an ordinary infantry brigade. He surrendered because he lacked air defense weapons and couldn''t fight against land ships.


    However, after landing on the ground, Chen Xin was really surprised to hear from the company responsible for collecting weapons that the brigade was equipped with not only anti-aircraft guns, but also anti-aircraft missiles.


    The land ship is really strong, but it is not invincible. It will still be damaged more or less in the face of air defense fire.


    In particular, air defense missiles, although they are designed to attack aircraft and shoot down incoming missiles, this does not mean that they are useless for land ships.


    On the contrary, if it is hit by anti-aircraft missiles, even land ships will suffer heavy losses.


    Therefore, under the previous circumstances, as long as the garrison fired missiles at the land ship, it still had a chance to shoot down the land ship.


    However, they did not fight and fell, which really made Chen Xin feel incredible.


    "Maybe they don''t want to fight? The overall quality of the armies of European countries has indeed declined over the years, and there is no way to be poor in fighting will." the political cadres next to Chen Xin didn''t respond so much, but advised Chen Xin: "Now it''s more important for us to decide what to do next. Academician Chen, you''re here to inspect the logistics supply. It''s OK for us to take over the city in a short time. It''s impossible for the troops to stay here for a long time."


    Hearing what political cadres said, Chen Xin also nodded very seriously. He naturally knew these things.


    However, Chen Xin had dealt with this matter before, so he quickly led the topic to another direction: "the situation here has been reported before. When the German officials arrive, hand over the city to them.


    Seriously, I don''t have any confidence in these Europeans now. I doubt how they hold the line of defense! Now I want to suggest that China let them send someone to occupy Europe, so as to more effectively organize the forces of the whole Europe against aliens. "


    Chen Xin''s remarks are not just complaints and complaints. Chen Xin has always had such ideas and ideas since he began to inspect the situation in all parts of Europe and the operation of material transfer cities behind the defense line.


    The situation in all parts of Europe is not ideal. Although the security situation in all parts of Europe has picked up due to the activity of the joint security maintenance force, the material shortage caused by the poor environment and the material expropriation to maintain the front line against the consumption of alien organisms have also plunged the whole of Europe into the misery of people''s decline and starvation.


    Although it is said that this is the reason why European countries have invested most of their resources in the front line to fight against alien invasion, looking at those yellow faced ordinary people, Chen Xin still feels deeply dissatisfied with European countries.


    Before, he didn''t go deep into the cities of various countries and didn''t know much about the situation. He thought that a series of people''s livelihood problems were caused only by the fact that European countries deployed a large number of troops to fight against alien creatures, resulting in their inability to maintain domestic law and order and the lack of labor force for productive labor.


    He also wondered whether to open some livelihood technologies to European countries to help them improve their production and living conditions, make people of all countries live better, and have more power to resist the invasion of alien organisms.


    But in fact, it''s not the same thing at all.


    It is a fact that Chen Xin saw the decline of people''s lives. However, this situation was not caused by the poor living environment in various countries because they deployed a large number of troops to fight against alien creatures.


    The root cause of all this is still the contempt of the officials of various countries for the ordinary people, and they don''t pay attention to their life and death at all.


    For European countries, what really deserves their attention is the things related to their vital interests. What needs to be concerned is still the so-called elite. Ordinary people don''t need to care whether they live or die.


    Under such a premise, European countries are only passively maintaining the survival of ordinary people. Compared with the endless squeezing of ordinary people by the armed separatist forces, the officials of various countries are just not so cruel.


    Or in other words, the officials of European countries do not treat ordinary people as disposable consumables and give them some possibility to live, just to squeeze them better.

 Chapter 774

    Just like what I learned in textbooks, the ruling class will always squeeze and exploit the ruled class. Even if it occasionally releases goodwill to improve the living conditions of the ruled class, it is only for better exploitation.


    For European countries, whether they fight against the invasion of alien creatures or form a joint security force to maintain domestic security, its essence is still just to safeguard their own interests and survival.


    Improving the living conditions of ordinary people is conducive to safeguarding their interests, and they will really do it.


    Otherwise, even if Chen Xin provides them with better technology, there will still be very few that can really improve the living conditions of ordinary people.


    Perhaps under the huge difference in the formation of black technology brought by Chen Xin, the living conditions of ordinary people will be significantly improved, but there will be no change in essence.


    It may even happen that when the ruling classes of various countries control the benefits brought by these technologies and enjoy a better life, they still put ordinary people under their original living environment.


    As for excuses, Chen Xindu has helped them think about them. Because a lot of resources need to be used to maintain the battle against alien creatures, countries are unable to improve people''s livelihood for the time being.


    Thinking of this, Chen Xin even had an idea of "destroy it, hurry up" and felt that these countries in Europe were really hopeless.


    Of course, he can''t really do that.


    After all, when he was walking in Nuremberg, he looked at the miserable appearance of ordinary people and was moved with compassion. He didn''t want them to fall under the minions of alien creatures.


    "Go and urge the Germans. If they don''t want the city, we''ll take over the city." maybe the appearance of ordinary people in Nuremberg stimulated Chen Xin. After waiting for two days and the official German people haven''t arrived, he asked people to send an ultimatum.


    "Academician Chen, isn''t it not good to say so?" the political work cadres stopped Chen Xin''s order and persuaded him.


    Chen Xin has the highest authority of the European aid fleet and the troops sent by Yanguo in Europe. Although he has no command, if Chen Xin really makes any decision, both the European aid fleet and the Yanguo troops in the joint security maintenance force will follow his decision and execute his orders.


    Under such circumstances, in terms of the strength of the two, in the current environment, it may be understaffed to control a country, but it is easy to control a city or surrounding areas.


    Even due to the deterrence of force, European countries will not have any strong reaction to it. At most, it will be over with a few words of protest.


    But being able to do so and wanting to do so are completely different things.


    Although the political work cadres understand why Chen Xin has such feelings, and even he is thinking about whether to simply practice the ideal of our ancestors'' red flag all over the world, if they really do so, they still need to take into account the consequences and impact.


    After all, if you really do so, it is likely to affect the front line of defense and shake the defense against alien creatures. If it really leads to the collapse of the front, it will lose too much.


    Although it is said that the Eastern European defense line has completed the main construction and can play a role in resisting the invasion of alien organisms, as said at the beginning, no one wants this defense line to really play a role.


    And more importantly, once the current defense line collapses to the point where it needs to resist the invasion of alien creatures in the defense line of Eastern Europe, the whole Europe will also be occupied by alien creatures, and a large number of land and population will fall.


    In order to avoid this possibility, political cadres feel that they still need to persuade Chen Xin not to do things too impulsively.


    "Well, let''s put it another way and express the meaning." after considering it, Chen Xin still chose a less aggressive statement, but his attitude is still very firm.


    Of course, the meaning of political work cadres is not just another way of saying it, but Chen Xin''s attitude is firm. After his attempts to persuade failed, he can only let people convey Chen Xin''s meaning to German officials.


    Political cadres are opposed to taking over the city of Nuremberg.


    After all, this is a city under the official control of Germany. Although the German officials lost their actual control of this place because of the garrison problem, it is still nominally under the official control of Germany.


    Temporary military control can also be said to be the need to maintain law and order. After all, the role of the joint law and order maintenance force is to maintain order in all countries.


    Before, German officials did not express any dissatisfaction with this, and even thanked the inflamed country for solving the problem of the garrison in Nuremberg. After all, before, they also suffered from the eating of this force, but they have been laissez faire because they were unwilling to bear the possible losses caused by the elimination of this force.


    It is no doubt better for German officials to solve the Nuremberg problem and restore their substantive control.


    However, if the inflammatory state officially takes over Nuremberg, the nature of the problem will change, which will involve deeper things and bring very serious consequences.


    Therefore, political cadres have always wanted to persuade Chen Xin not to do so. However, Chen Xin seems to be stimulated by the official attitude of European countries towards ordinary people. Now his attitude is very tough.


    This undoubtedly made the political cadres very scratched. On the one hand, he did not want to lead to any serious consequences, but on the other hand, he also wanted to support Chen Xin''s practice. Under the embarrassment of both sides, he finally sent a note to the German side and asked them to send someone to take over Nuremberg as soon as possible.


    However, the German side gave a very speechless answer, which made the political cadres feel that it might be better for them to take over Nuremberg directly.


    "Due to traffic problems, the staff who went to Nuremberg to take over the city could not arrive on schedule. Please let the citizens form a Municipal Committee for autonomy and maintain the material transfer to the front line."


    Traffic problems make it impossible for the staff taking over the city to arrive on time, so let the citizens exercise autonomy?


    Political cadres do not believe this at all.


    If it is really a traffic problem, they can turn to the Yanguo side for help. There is no problem sending a land ship to help pick up the staff.


    But the German government has allowed citizens to govern themselves, which is astonishing.


    This is completely like trying to take control of the city, but no one is willing to come or the internal benefit distribution has not reached an agreement.


    Looking at this reply, political cadres really think that maybe it would be better for Yanguo to take over the city.

 Chapter 775

    In the end, the country did not formally take over Nuremberg, nor did it maintain military control.


    This is certainly not because the official German people arrived and took over the city from them again.


    In fact, the German officials sent to take over the city were still unable to arrive because of "traffic problems" until Yanguo took the initiative to lift the military control.


    Chen Xin asked people to ask and urge them several times, but he always got the answer of "traffic jam, please hand over the city to citizens'' autonomy and maintain material transfer".


    Such an answer undoubtedly makes Chen Xin very angry, and even has an idea of simply ignoring it and dying with the city.


    But in the end, he didn''t go so far.


    After all, once the troops of the inflamed country and the joint security forces withdraw, the situation in Nuremberg will deteriorate visually, and it will become unknown whether the materials supporting the front line can be transferred smoothly.


    As for the possible consequences of this, no one knows.


    The city can''t let it go, but there are all kinds of problems when it takes over. After Chen Xin was almost scratched by the difficulty of the hatchback, he still thought of a solution to the problem.


    He chose to really let the people of Nuremberg take over the city themselves according to the reply given by Germany.


    However, unlike the German government''s expectation that the city will be self-made by the people and still belong to the German government, Chen Xin put forward a new proposal for these people who appear to be flustered and frightened after convening the people''s representatives of Nuremberg and field and informing them that the inflammatory army will be deregulated and the joint security forces will withdraw, That is, Nuremberg and field declared urban autonomy.


    It should be noted that the urban autonomy here is completely different from the citizen autonomy hoped by German officials.


    Although they are all autonomous, the former means to turn cities or regions into independent administrative divisions. Although they still belong to Germany in name, they will not obey the orders of German officials or obey the jurisdiction of German officials.


    Civil autonomy is just to hand over the management of the city to the people themselves, let them maintain the operation of the city, and the city is still controlled by German officials.


    For German officials who have not sent official staff to Nuremberg for some reason, whether Nuremberg declares autonomy or not has little impact on the current situation in Germany.


    In other words, in the view of German officials, if the actual control of cities cannot be recovered, there is little difference between letting them be controlled by civil autonomy or separatist forces.


    The worst thing is that a city declares independence, which is really painless for German officials who have not mastered the city and control.


    After all, it''s out of reach anyway, so what''s the big difference between who owns the city? It just sounds better in name.


    It is even possible that for German officials, it is better to let them govern where they are unable to manage for the time being, which can save some resources. After all, controlling the city still requires some investment.


    But for the citizens of Nuremberg, there is a big difference between the two.


    For citizens'' autonomy, all they can do is to maintain the continuous operation of the city, especially the operation of the most critical material transfer, so as to continuously deliver supplies to the front line of defense, and continue to pay taxes to German officials.


    That is, although they enjoy the right of autonomy, they still have to be under the jurisdiction of the official administration and pay taxes.


    As for autonomy, it is basically equivalent to independence. Although it is nominally attributable to a country, in addition, it is equivalent to an independent country.


    For the people of Nuremberg, the only thing that may need to be discussed is that they need to continue to maintain the transfer of goods to the front line.


    In the face of official inaction and the inconvenience of Chen Xin and his countrymen to intervene, the people of Nuremberg finally chose independence and autonomy.


    They have been deeply hurt by the official inaction of Germany and lost their trust, so since they are all autonomous, why not just a little?


    Therefore, under such circumstances, it is not difficult to understand that Nuremberg chose independence and autonomy after breaking away from military control.


    It can be said that from the previous semi separatist regime of the garrison, he has made a round trip, but he has taken a real separatist regime in Nuremberg.


    In the face of such a result, Chen Xin doesn''t matter. It''s just that everyone is busy in vain.


    However, after the autonomous Committee established by the people of Nuremberg agreed to Chen Xin''s request and will continue to transfer materials to the front line, the situation is still somewhat different.


    At least the autonomous committee will not float away the transferred materials. At most, it will only obtain some materials from them to maintain the operation of the city, which virtually reduces a lot of consumption, so that more materials can be transported to the front line and make more contributions to human beings against the invasion of alien organisms.


    In fact, for Chen Xin, if the officers of the garrison were not frightened by the two land ships and suddenly surrendered to him, he would not really care about Nuremberg.


    Now after such a toss, although it seems that he has done white work, the existence of those surrendered garrison still proves to Chen Xin that he has done something in this trip.


    These surrendered garrisons were handed over by Chen Xin to the autonomous Committee for disposal.


    After some discussion by the self-government Committee, they chose to expel the official German army.


    After all, the whole city didn''t like the army that was still dominating the city.


    Although the presence of this garrison makes Nuremberg''s public security relatively stable, and some armed forces around do not dare to make trouble, objectively speaking, it has protected the people of Nuremberg, but this does not prevent them from expelling this force.


    As for what to do with the security and defense work in Nuremberg after the expulsion of this force, the autonomous committee plans to form a militia by itself to defend its own city.


    In order to help these people and supervise whether the autonomous committee will try its best to maintain the material transfer work, Chen Xin informed the European aid fleet and asked the fleet to send a working group here.


    The main task of the working group is to supervise and inspect the transfer of goods in Nuremberg, while assisting the members of the self-government Committee and helping them train the militia.


    The autonomy committee also plans to purchase the weapons and equipment used by the militia from the inflammatory state. Therefore, after making a detour, Nuremberg''s control is equal to being controlled by the inflammatory state.

 Chapter 776

    Although what happened in Nuremberg has brought a lot of trouble to Chen Xin, after ending what happened in Nuremberg, Chen Xin still got a lot of inspiration from it.


    For the current European countries, in order to ensure their actual control over the territory, in addition to eliminating the armed separatists in the territory, the most important thing is to send people for administration.


    This is not only to maintain urban law and order and tax collection, but also other issues related to it need the intervention of the actual controller of the city.


    It is precisely because of this situation that, with the activity of the joint security forces, the main separatist forces in the territories of European countries have been eradicated, but the officials of various countries lack the necessary personnel to take over these territories.


    Because the officials of various countries have sent out all the people they can shoot, now they have no spare power to take over the new city.


    Therefore, in the past, although the joint security forces had the ability to expel or eliminate the armed separatist forces in European countries, in the end, they could only expel the armed separatist forces in the main areas of various countries.


    Other places were abandoned because they lacked the necessary manpower to manage them, and the armed elements who had been cleared once soon reoccupied the area, resulting in a stalemate with the joint security forces.


    This time, what happened in Nuremberg opened a hole for Chen Xin and gave him a lot of enlightenment.


    Since the manpower is tight and unable to maintain local law and order and management, and even the number of troops stationed in the city is seriously insufficient, let the city govern itself and form its own militia to maintain urban law and order.


    This approach can greatly alleviate the situation caused by the shortage of manpower in European countries, and allow more cities to give full play to their original productivity.


    We should know that when most of the troops of various countries are stacked on the front line of defense, countries can not actually transfer much military strength. As a multinational mixed organization, the joint security maintenance force also reflects this problem in a certain way.


    After all, the size of the joint security force is only one brigade. For a single country, it may not be able to afford it, and there are not so many people.


    However, for the consortium of major European countries, this scale is too small. If possible, they obviously hope to train more troops equipped with inflammatory national armaments, which can also be used to maintain their rule in addition to sending them to the front line to resist alien creatures.


    However, after what happened in Nuremberg, Chen Xin clearly realized that the lack of manpower to manage a city or an area can allow the local people to manage themselves, lack troops, or form militias to defend their homes.


    As long as some staff are sent to guide and help, such autonomy can save a lot of manpower, restore control over the originally separated areas, and have good production efficiency.


    Therefore, after discussing with the European aid fleet and reporting to China that he has obtained permission, Chen Xin plans to "let go and mobilize the masses" among European countries.


    The armed separatist forces in a city or an area will be eliminated through the settlement of the joint security forces, and then the people''s self-control will be fostered.


    We only need to send a working group to assist them in their work in the early stage so that the autonomous committee can operate. These cities that were originally occupied and could not provide resources or manpower can play their due role again.


    With the launch of this plan, a considerable area was quickly restored to control, and because these newly restored areas were located in the original resource mining area, the materials and raw materials available to the European aid fleet became rich all of a sudden.


    But this also exposed a problem. All of a sudden, the actual control area increased so much, which not only brought management pressure, but also put forward the demand for the maintenance of public security.


    The formation of militia to maintain law and order is certainly a method, but what the militia can guarantee is only local law and order. More places still need joint law and order maintenance forces to maintain order and order.


    However, due to the size of the joint security forces, the area they can maintain and cover is also limited.


    After all, there is only one brigade. Although there are more than 30 land ships, if they are spread to the whole of Europe, this force is really not worth mentioning.


    So this leads to the establishment of a new armed force if we want to expand more controlled areas.


    What they need is not the garrison stationed in the city. This role has been played by the militia. What this new armed force needs to play is the role of patrol.


    With a certain mobile force and force, it is not passively stationed in a certain city, but like the joint security maintenance force, it can patrol and maintain law and order in more areas.


    Moreover, it is better for this army to be an autonomous armed force like the local autonomous committees, rather than a puppet armed force established with the support of the inflammatory state.


    After all, China''s input in Europe is also limited, and it can not really form a controlled armed force.


    This is neither necessary nor good.


    This demand makes Chen Xin think that the organizational form is actually the Knights.


    Chivalry can be said to be a specialty of ancient Europe, and the knights, as a military organization, did play a role in maintaining law and order at that time.


    Although to a large extent, the Knights are more used in war as a military organization, it has to be said that a knights can really effectively maintain order and security in a large area.


    Moreover, according to Chen Xin''s idea, what he wants to establish is not a feudal knights in the traditional sense, but an organization more similar to the Rangers.


    First of all, adhering to the principle of voluntariness, the order will recruit people and raise military funds from the autonomous cities in its region, then establish and train armed forces with the help of the European aid fleet, and then conduct regular patrols and security maintenance in the region with its own mobility, so as to ensure order in the region together with the militia forces.


    If this system can work, the militia will be more responsible for urban public security in the areas controlled by autonomous cities, and its function will tend to the police.


    The Knights are more used to be responsible for the security of the whole region, clean up the possible armed forces or affect the existence of regional security, and shoulder the task of fighting together with the joint security maintenance force, and their functions tend to the army.


    After Chen Xin put forward this plan and idea, although the European aid fleet was not optimistic about it, the autonomous cities established during this period were very interested in the plan, and several knights were also established with their support and soon played a role.

 Chapter 777

    The knights, of course, can''t really be like those tin cans on horses in the middle ages.


    In fact, even if they want to ride a horse in a retro way, there are no horses for them in this environment now.


    Although in a sense, this regional armed force does need mobility, riding is also a way to solve the problem when there is a lack of cars or other modern means of transportation.


    However, what Chen Xin prepared for these "knights" were snow motorcycles and snow vehicles. Of course, they were all equipped with isotope temperature difference batteries.


    Now Yanguo has fully understood the isotope temperature difference battery technology provided by Chen Xin and can produce this "nuclear powered" vehicle.


    In fact, domestic vehicles that almost never need to refuel are widely used. Nuclear powered snow motorcycles with protective clothing are the first choice for most people who need short-distance travel. Although driving is OK, cars are mostly used for long-distance travel.


    After all, it is light, flexible and easy to use. On the premise that one or two people commute in a short distance, snow motorcycles are really easy to use.


    Chen Xin does not intend to provide land ships to these knights. In fact, they don''t even have a mobile base that can''t fly. They just obtained a small military camp composed of movable plank houses and functional shelters from the European aid fleet.


    As for snow motorcycles and other means of transportation, as well as the weapons equipped by the knights, in addition to a set of exoskeletons to improve combat ability and protective clothing to deal with extremely cold environments, the weapons of these knights are still ordinary guns and a small number of heavy weapons.


    This is mainly due to the consideration of the combat functions of the Knights. After all, they have to face only ordinary militants, not alien creatures that can eliminate 9mm caliber bullets.


    According to the plan discussed by Chen Xin and various autonomous cities, a knight order will be responsible for maintaining the order of three to five autonomous cities according to the size of the city. Its main need is to face armed elements with certain force.


    Since it is fighting against people, of course, there is no need for heavy weapons such as electromagnetic rifles and heavy machine guns.


    The reason why they left them some heavy weapons was mainly to prepare for a rainy day. Usually, these knights can only use ordinary guns and throw explosives.


    The expenses of the Knights are mainly provided by the cities they are responsible for. These cities regularly pay certain funds to the Knights and are responsible for providing daily materials, while the Knights need to maintain the peace and stability of these cities as much as possible.


    With the knights, a security system composed of joint security forces, autonomous militias and the Knights was formed.


    In this system, the joint security force is naturally the main military force. With sophisticated weapons and equipment, they are responsible for the clearance of large-scale armed separatist forces. They have good mobility and can be responsible for a considerable area.


    At ordinary times, it is not stationed in a city, but takes land ships as the base and regular patrols as the main activity mode.


    The militia is the main public security force in the city. They are not very armed. They only have a small number of light weapons such as police pistols, which are scattered in their respective cities, doing the work of the former police and responsible for maintaining urban public security.


    As for the knights, they are a supplement between the two. They have a certain armed force, mainly as a supplement to the joint security forces.


    After all, the joint security forces are limited to the size of the forces and the mode of action. Their main work is to clear up and deal with large-scale armed separatist forces, such as remote areas or small-scale armed forces. They are obviously overqualified.


    The Knights are just an effective supplement to the joint security forces. They can be stationed in a certain area for a long time, assign people to patrol the main cities and residential areas in the area, and even disperse in multiple cities. Cooperating with the militia can effectively maintain the security of the area.


    It is precisely because of this advantage that the scheme of establishing the knight order has been supported by various autonomous cities.


    Soon, several knights were established with the support of these autonomous cities, which also effectively improved the local security environment.


    With the joint efforts of the security forces, the militia and the knights, the areas with chaotic order and serious armed separatism have rapidly stabilized. The establishment of autonomous cities has made a large number of people and resources that were not officially controlled by European countries reused and become a strong support to the front line.


    After all, neither European officials nor Chen Xin will obviously allow such a large force of autonomous cities to drift away from the war against alien creatures.


    Although officials of all countries can not effectively control autonomous cities and can only recognize their existence by pinching their nose, this does not mean that officials of all countries really have no way to take autonomous cities.


    After all, they are the original legitimate rulers of various countries. If the officials of various countries who control the armed forces such as the army are really forced to be anxious, there is no problem in biting their teeth and mobilizing the army to kill chickens and monkeys by cutting open autonomous cities.


    Therefore, as the cost of official recognition of urban autonomy, autonomous cities need to pay taxes to national officials to support the front-line combat against alien creatures.


    Fortunately, each autonomous city also understands that it largely depends on the front line to resist the attack of alien creatures, so there is no objection on this point.


    Autonomous cities need to pay taxes to support the front line, and the Knights are no exception.


    Although they are not military, they are also military organizations. Although these knights are only supported by autonomous cities and have no source of income, they also need to pay taxes.


    However, what they need to pay is not the resources of autonomous cities, but to send some people to directly participate in the front-line operations.


    Fighting against alien creatures naturally requires dead people, so this tax method is also jokingly called "blood tax".


    According to the regulations, after the establishment of each knight regiment, one quarter of its people need to be transferred to the front line every three months to participate in the battle of alien creatures, and one quarter of its people will be sent for rotation after three months.


    In this way, a knight order is basically equivalent to three months of service on the front line in a year.


    Originally, Chen Xin and officials of various countries thought that the knights would oppose this request, but they did not expect that after the request to collect "blood tax" was passed down, the Knights did not show much resistance.

 Chapter 778

    On the defense line against alien creatures, Bob is fighting bravely in his own power armor.


    The armor piercing incendiary bomb ejected from his three barrel heavy machine gun is very efficient in harvesting the lives of alien creatures, so that the burning corpses quickly lay a fire wall in front of the defense line.


    This is a recently popular tactic. Armor piercing incendiary bombs are fired from heavy machine guns to kill and ignite the bodies of alien creatures, and then electromagnetic rifles are used to kill other alien creatures illuminated by fire.


    This has two advantages. First, it can illuminate the battlefield by igniting the corpse, so that other soldiers can obtain the field of vision and range. At the same time, the igniting corpse is also a natural obstacle, which can cause a certain delay to the attack of alien creatures.


    After all, out of biological instinct, alien creatures are essentially afraid of fire. Even under the control of the upper node, these alien creatures do not have the ability to think independently and will be fearless of death.


    And the size of alien creatures is huge. Other alien creatures need to climb when they continue to attack. In the process of climbing, it will undoubtedly make alien creatures more conspicuous and easier to be shot.


    Looking at a small slope piled up with the bodies of alien creatures, Bob was very satisfied with the killing effect of the heavy machine gun on his power armor.


    "Change ammunition!" Bob noticed that his heavy machine gun was about to empty bullets. After shouting, he stepped back two steps. After emptying the last few bullets, he picked up a new bullet chain from one side and loaded it on the machine gun.


    A soldier on one side quickly helped Bob remove the original empty bullet chain case and install the new one.


    After Bob moved and checked that there was no problem, he nodded to the soldier, took a few steps forward again and rejoined the battlefield.


    While pulling the trigger and feeling the shock caused by the bullet, Bob''s thoughts suddenly drifted for some reason.


    Several months have passed since the end of the three-month service in the joint security maintenance force and returned to the front line. Even the second batch of soldiers trained and dressed in the joint security maintenance force have returned.


    These formally trained soldiers, together with the exoskeletons and power armor brought back, greatly improved the combat effectiveness of the original troops in the face of alien creatures, and killed a large number of alien creatures more efficiently.


    The improvement of combat effectiveness brought by these soldiers and equipment undoubtedly makes the defense line more stable. The defensive pressure on their defense line is obviously not as strong as before.


    At least in Bob''s impression, they haven''t had an urgent defense in recent months. Almost all problems have been solved by themselves. Compared with before, they have greatly improved and the defense has become a lot more stable.


    Among them, the greatest credit naturally belongs to Bob and his soldiers who have changed their new equipment, but at the same time, some credit also belongs to those "knights".


    With the establishment of the first knights and the collection of blood tax, the first knights were soon assigned to the defense line to help the defenders fight against alien creatures.


    Originally, they didn''t care much about this army, which also has exoskeletons, but still uses traditional guns. In particular, they still use the title of "Knight" very retro, which makes people feel that they are just fun.


    But Bob didn''t think the "knights" were worth laughing at. He just felt that they were useless in frontal combat.


    After all, 7.62mm caliber bullets can not penetrate the skin of alien creatures, and can only be used to kill those militants who disturb public security. The weapons of these "knights" are destined to play little role.


    However, these Knights also had a good command of self-knowledge, and knew that their weapons suck up, and then they volunteered to take up the work of auxiliary warfare.


    Although they were only equipped with ordinary guns, their exoskeletons were no different from others. With the addition of machinery to power, these "knights" soon became very excellent auxiliary soldiers on the battlefield.


    Just like just now, it was a "Knight" who helped Bob change his ammunition, which greatly saved Bob''s time to change his ammunition.


    On the battlefield, one second is enough to decide life and death. It can save time and change direction, which plays a role in improving combat effectiveness.


    This also makes these "knights" quickly recognized by the soldiers. Although some people will ridicule them as "knights", they have undoubtedly won the respect of other soldiers.


    Bob chatted with the "Knight" while creating another flame slope.


    Now there is little pressure on the battlefield. Even if Bob continues to fight, he has enough margin to chat with others.


    "Anton, I heard that the second batch of members of your knights are coming soon?" Bob asked the "Knight" next to him after another beautiful shot.


    The knight nodded politely and kept working. "Yes, the second batch of members of the regiment who came to pay blood tax will return next week. After that, they will take over our work and continue to provide battlefield support for you."


    "That''s great!" Bob said after he shot a short shot and killed an alien that missed the wall of fire. "I hope they can be as good as you. When you go back, I''ll miss you."


    "Ha ha, please rest assured that the members of our knights are very good, and they will make you satisfied." the knight smiled, distributing new ammunition to others and full of confidence in the coming new "knights".


    Although the Knights'' order has not been established for a long time, and the first Knights'' order only has a history of a few months, as a collective, the members of the Knights'' order have trained together, so they know each other and have a good degree of trust.


    Therefore, this knight will show confidence in the coming New knights, which is the trust in the comrades in arms of the same collective.


    Bob nodded without saying anything more, but continued to fight with alien creatures with his mecha team composed of all soldiers equipped with power armor, and every soldier wearing power armor had a knight around him.


    The main work of these knights in the trenches was to carry ammunition from the rear ammunition depot, replace ammunition for weapons and equipment such as power armor and heavy machine guns, and assist other soldiers in combat.


    Although they were only auxiliary operations, it was obvious that these Knights did a good job.

 Chapter 779

    "Academician Chen, I still think you shouldn''t go to the front in person. It''s too dangerous." in the bridge of the frigate, Chen Xin is standing in front of the window and looking out with a telescope. The political cadres beside him are still trying to persuade him to change his mind.


    However, Chen Xin didn''t care about it. He put down his telescope, turned to the political cadres and smiled at him: "when I came to Europe, my main job is to assist the European aid fleet and help Europe resist the attack of alien creatures. This line of defense is the key to Europe''s fight against alien creatures. If I don''t come to see it myself, wouldn''t I be the same as I didn''t come to Europe?"


    "But academician Chen, you have done so much work. In the past few months, the overall order in Europe has been improved, and the output of various materials, reserve sources and weapons and equipment have been greatly increased. You have made a lot of contributions to the fight against alien creatures, so there is no need to take risks in person!" political cadres obviously disagree with Chen Xin''s words, Still trying to persuade him: "and when you came, you promised the top that you wouldn''t do dangerous things. It''s against the agreement reached between you and the leader to go to the front in person!"


    Before Chen Xin came to Europe, the task assigned by the leaders to this political work cadre was to let him watch Chen Xin and not let him do dangerous things, let alone go to dangerous places.


    The best thing is to tie him with a rope, let him stay on the frigate, and directly let him return home after doing things, so as to avoid any danger that may pose a threat to Chen Xin.


    However, no matter how political cadres oppose and persuade, Chen Xin still insists on coming to the front line to inspect the defense of the defense line and understand how Europeans are doing in resisting alien invasion.


    After all, he helped the European aid fleet provide massive materials and a large number of trained personnel for the front line, which can be described as greatly enriching the European defense line and improving the defense line''s resistance to alien creatures.


    Under such circumstances, Chen Xin was naturally very curious about how much help he had done in the rear to the front line.


    In addition, he also wants to know what the alien creatures resisted by the European defense line look like, what is the difference between them and China, and whether the European experience in resisting them can be used for reference in China


    On the other hand, Chen Xin also needs to know the use of the reduced version of exoskeleton and power armor he provided to European countries on the front line, whether there is any need for improvement, and collect relevant data for reference when developing the next generation of exoskeleton and power armor in China.


    Chen Xin''s political cadres naturally understand these reasons. He also understands how important it is for him to develop more and more effective weapons and equipment to eliminate alien organisms when researchers like Chen Xin come to the front and feel the invasion of alien organisms.


    However, it is precisely because they know the importance of Chen Xin that political cadres should prevent Chen Xin from going to any place judged to be dangerous.


    After all, all this depends on Chen Xin. It can be said that he alone has been related to the war situation against alien creatures all over the world, not to mention his significance to Yanguo. The senior leaders of Yanguo want to put him in the safe.


    However, under Chen Xin''s persuasion, the senior management agreed to him and allowed him to interview relevant personnel and collect relevant data.


    However, all this should be carried out under the supervision of political cadres. Chen Xin cannot act alone. After arriving in the frigate, he can only stay on the frigate and must not take any dangerous actions.


    Therefore, after obtaining the permission of the high-level, Chen Xin took a frigate and followed a batch of materials to reach the material hub set up behind the defense line in European countries.


    These hubs are located behind the defense line. Although they are still some distance from the front line, they can also feel the smell of war here.


    All kinds of materials transported from the rear need such a hub for coordination and distribution, and the damaged weapons and equipment on the front line will also be sent down here for maintenance


    A large number of materials are distributed here to maintain the operation of the front line of defense. In addition, a large number of personnel from the rear to support the front line will also be uniformly distributed here, so that these reinforcements can be distributed to the defense line in a more reasonable way, rather than sprinkling pepper or simply rubbing piles.


    At the same time, the supply of front-line troops also needs these material hubs to solve the problem. All kinds of materials sent from the rear will be redistributed here and sent to the front line in a balanced manner as much as possible, rather than sending what they have to the front line as they did when there was a shortage of materials.


    It can be said that all the information Chen Xin wants to know can be obtained here. Even if he knows the first-hand information of the battlefield, there are soldiers who have just withdrawn from the front line in these material hubs. They are enough to answer Chen Xin about the latest situation on the front line.


    According to the idea of political cadres, Chen Xin can arrive here. All the information he needs to know can be collected here. He doesn''t need to go to the forefront of the defense line in person.


    However, Chen Xin did not stop here.


    After staying at the material hub for a few days, although a large number of valuable data have indeed been collected, Chen Xin still hopes to personally go to the forefront to understand a more intuitive situation.


    This naturally attracted opposition from political cadres.


    "My agreement with the senior management is that I will not do dangerous things, which does not conflict with my desire to go to the front." facing the obstruction of political cadres, Chen Xin explained to him: "Although in the material hub, I can collect the data I want by interviewing the soldiers withdrawn from the front line, many data are still not comprehensive and detailed enough. Many things can more intuitively understand the information I want to know only when I go to the front line in person and look with my eyes, so I have to go to the front line."


    Hearing what Chen Xin said, the political cadres were in a hurry. However, before he said anything, Chen Xin raised his hand and stopped him.


    "Of course, I will abide by the agreement between me and the leaders, and I will not joke about my life. Although I want to go to the front line, I promise I will stay in a safe place and will not take risks." Chen Xin tried to convince the political cadres and promised him.


    Although the political work cadre has been singing against him, Chen Xin knows that the other party is also thinking about his own safety, so he does not have to go to the front line, but adopts the way of persuasion, hoping to obtain the consent of the political work cadre.


    Chen Xin''s attitude made him helpless, and the political work cadres finally did not continue to block him, but he still put forward conditions for Chen Xin, requiring that all his actions in the forward position must be arranged according to his own arrangements, and there should be no risky behavior.

 Chapter 780

    On Chen Xin''s way to Europe, he once looked down from the sky on the frigate at the Eastern European defense line under construction.


    He was deeply impressed by the construction site that spread from one end of the line of sight to the other end of the line of sight, like a giant dragon across the earth.


    However, although the defense line under construction is large in scale, it is still inferior to the European defense line that has been put into use and is fighting fiercely almost all the time.


    At this time, Chen Xin''s land frigate has reached the forefront of the European defense line, and below them is the most intense forward position.


    Here, even in the air, there is a certain danger.


    Because the air units of alien creatures will launch air raids from time to time to try to break through the defense of the defense line from the air. If they encounter these flying units in the air, it will undoubtedly pose a certain threat to the frigate.


    Although for the land frigate, relying on the anti-aircraft weapons on board will not be afraid of those flying units, no one can guarantee whether there will be accidents.


    During Chen Xin''s flight to the forward position, they have encountered at least three groups of flight units, which makes Chen Xin even think that mankind has lost the air control over the defense line.


    Of course, not really.


    In the face of alien creatures penetrating the defense, the air defense weapons arranged on the defense line will play their due role and beat down these flying units.


    Looking at the track of the tracer bullet on the ground from time to time, which is like a whip flashing electric light, pulling from the ground to the sky, Chen Xin has a very intuitive understanding of the battlefield.


    Although it is said that air defense weapons are the first weapon that Chen Xin sees to be powerful in the forward position, in fact, the soldiers in the trenches in the front of the position and the weapons they are equipped with are the most direct collision and confrontation with alien creatures in the forward position.


    Because alien creatures are attacking like a tide all the time, the front end of the front position is a line of defense that is also fighting fiercely all the time.


    Looking down from the sky, you can intuitively see that the whole defense line is bright.


    It was not a light, but the light of the fire from the muzzle of the shooting gun in the forward position.


    Originally, the flame at the muzzle was just the moment when the bullet was fired. It could not illuminate much range or last long.


    However, with the almost non-stop shooting at the muzzle, these weak flames gathered together and lit up the whole line of defense.


    Looking at the fire like a flaming dragon, Chen Xin really felt the fierce battle.


    Although I have seen the fighting situation between the army of Yanguo and alien creatures in the front line of the Dongting Lake theater in China, I have to admit that there is still a difference in the intensity between the two.


    Perhaps it is because the scale of alien creatures on this side of the European battlefield is larger, so their attacks are more intense!


    Because there is no sunshine, the earth is black, but on the other side of the line of defense illuminated by the fireworks, the dark earth seems to be alive. Under the weak light, it constantly rushes towards the line of defense like waves, just as the sea always beats the coast, and this offensive seems to never stop.


    Chen Xin clearly knows that within the scope of his eyesight, on the other side of the defense line, all the ground is covered by alien creatures. They are literally attacking like a tide.


    This is not an exaggerated description, but a very realistic description, because there are indeed as many aliens as the number of oceans.


    "If I throw a nuclear bomb, I don''t know what effect it will have?" Chen Xin said to himself, but he was wondering whether it would be worthwhile to do so.


    Although limited by the light problem, Chen Xin can''t really see the specific situation of the "vast ocean of insects", he can guess how much. I''m afraid even if a nuclear bomb hits, it will only empty a number of alien creatures in a short time, forming a hole, and then it will be filled by other alien creatures in an instant.


    Of course, there is no doubt about the power of nuclear bombs, but there are indeed too many alien creatures.


    In addition to the trenches at the forefront of the defense line and the anti-aircraft artillery filled behind the trenches, humans also arranged additional artillery positions as fire support.


    It may not be true on the ground, but you can clearly see the rear of the defense line in the sky. The light generated by a firing bullet across the sky hit the alien creatures in front of the front position. As Chen Xin expected, it hit craters one by one, created a blank in a short time, and then disappeared in a moment.


    Relying on the cooperation of three different configurations on the defense line, mankind firmly blocked the alien creatures out of Europe by relying on such a seemingly thin defense line, and did not let the alien creatures continue to deepen and spread.


    In fact, Chen Xin''s contribution is very significant.


    Although the current defense line seems to be very stable, and a large amount of ammunition pouring down is enough to defuse the attack of alien creatures, these defense lines were already crumbling before Chen Xin arrived in Europe. From time to time, air support needs to be called to eliminate the enemy who has exceeded the bearing capacity of the forward position by several times.


    After the soldiers in the forward position gradually began to replace the equipment provided by Chen Xin, their combat effectiveness was effectively improved. When facing the attack of alien creatures, they finally began to pull back the city, which created a situation that the current defense line was stable and alien creatures were more or less killed.


    At present, Chen Xin is also thinking about the equipment he provides to European countries.


    Before seeing it with his own eyes, it seems that the earth is attacking you. Chen Xin''s impression of the European battlefield is basically similar to that of the domestic Dongting Lake theater. Therefore, Chen Xin adopts a specially designed reduced version of the equipment provided to European countries.


    However, now, looking at the scene of fierce fighting in front of him, Chen Xin couldn''t help asking himself whether he should provide them with more powerful weapons?


    Although the reduction of export allocation is a thing that countries will follow in arms export, the current scene makes Chen Xin feel that he should provide the original and improve every trace of valuable combat power against alien creatures.


    After all, the sight of "sea of insects" always makes people unconsciously feel afraid and want to seek a sense of security.


    For the terrorist upright apes, powerful weapons are the best source of security at present. The greater the power, the stronger the sense of security.


    But soon Chen Xin did not think about it again, but asked the captain to prepare for landing.

 Chapter 781

    "Bob, take your team and go to the headquarters!" in the stronghold, the major in charge of the command shouted at Bob who was resting: "there is a big man to inspect the defense line and pick us. You need to be responsible for the safety of that big man."


    Bob got up from his chair. His power armor was parked on a shelf to be checked by a technician.


    Hearing the major''s words, Bob asked him curiously, "big man? What big man will go to such a dangerous place on the front line to inspect? Let''s protect his safety. What about the combat mission? We still have an attack mission today!"


    "Your attack task is left to team B to solve. Now take your people to change their equipment and go to the headquarters!" the major didn''t talk nonsense to Bob, but gave his orders.


    However, when Bob went to get his team members to prepare their equipment, he still approached Bob and whispered to him, "this is a real big man. There is a land ship at the headquarters. You know what that means!"


    As a person trained at the European aid fleet base in Yanguo, Bob certainly knew what a land ship meant, which immediately made him stare.


    Seeing Bob''s reaction, the major knew he understood, so he patted him on the shoulder: "so do well! If you can show your face in front of big people, our whole defense will be good!"


    "I see!" Bob nodded solemnly, came to his armor and asked the technician to speed up the inspection.


    Bob understood why the major wanted him to behave well.


    Although with the development of the construction of Yanguo''s European aid fleet, at present, the whole Europe has greatly improved both material and order, various production has also been restored, and the conditions of their front-line soldiers are much better than before, on the whole, they are still very difficult.


    When he was trained at the base of the European aid fleet, Bob had seen the facilities and conditions of the Chinese people, which really made him very jealous.


    Not to mention the warm and comfortable barracks and the land ships that Yanguo people look like science fiction, or other dazzling facilities, the most exciting thing for Bob is the container style greenhouse cabin built by Yanguo people in the base.


    In today''s environment, it''s impossible to eat fresh vegetables and fruits.


    Even if there is still vegetable and fruit production in the rear, the transportation from the rear to the front has long become stale, even if the temperature is very low.


    So Bob, most of what they can eat are canned or processed food. As for fresh vegetables or fruits, that''s what Bob ate only when he was in the Yanguo people''s base.


    Therefore, the major''s words are naturally easy to understand. He should perform well in front of the big people, win the favor of the big people and get benefits for the stronghold they are stationed in.


    Bob doesn''t hate such things, and he doesn''t have the idea that he is a soldier and doesn''t want to be a bodyguard for big people.


    After the technician checked his power armor and confirmed that there was no problem, replaced the consumables and refilled the ammunition, Bob put it on again, picked up the weapon and walked out of the stronghold with the team members who had also changed their equipment.


    Compared with the warm environment in the stronghold, the outdoors is hell.


    Just as he walked out of the door, Bob saw that there was white frost on the observation window of his helmet.


    If the protective clothing used to drive the power armor has excellent thermal insulation and electric heating function, I''m afraid they will be frostbitten or even frozen to death at the moment they go out of the door.


    Before getting the help of Yanguo, their cold resistance mainly depended on multi-layer cold proof clothes to resist the attack of cold. Although the effect of cold proof clothes originally prepared for polar operations was also good, it still made people feel very cold. Moreover, their heads and hands must be wrapped in several layers, making the whole person look very bloated and stiff, It is far less light and comfortable than the protective clothing first provided in Yanguo.


    However, Bob was still trying to make complaints about his protective clothing, which was very satisfactory.


    This set of power armor is good everywhere. When he was training in Yanguo base before, he even had a limb illusion because he was reluctant to take it off. However, this set of power armor is criticized, that is, the armor itself is not sealed and does not have the function of keeping warm.


    Therefore, if you want to use power armor in cold environment, you must first wear a set of special protective clothing inside.


    This is undoubtedly very uncomfortable. After all, Bob clearly knows that the power armor of Yanguo people is isolated from the inside and outside. There is an internal circulation system, not to mention the life support system, which is much more functional than his own.


    Bob couldn''t help thinking that if he performed well and showed his face in front of big people this time, would he have a chance to get the power armor without simplified function? Or upgrade your own set and install all the functional modules?


    With this idea in mind, Bob''s pace was a lot faster. It was fifteen minutes from the stronghold to the headquarters. He arrived five minutes ahead of schedule and ten minutes later.


    Outside the headquarters, a huge land ship hovered at a very low altitude. Bob recognized it as the one he had seen in the European aid fleet base before.


    At that time, Bob heard that it was the ship of a big man in Yanguo. Because he wanted to come to Europe, he specially sent this land ship to Europe in order to protect his safety.


    Recalling this message, Bob was excited again. He knew that if he could really please the big man this time, he would certainly get something good.


    So Bob came to the headquarters with his team.


    After a briefing, they were allowed to enter the headquarters after they laid down their weapons in power armor.


    Being asked to lay down his arms undoubtedly made Bob nervous. It was obvious that such instructions were given to protect the safety of big people.


    As required, the team members were left outside. After unloading their weapons, Bob entered the headquarters and met the big man.


    Under the guard of two power armored soldiers who were obviously better equipped than him, a Yanguo man wearing only protective clothes was talking to the officers of the headquarters. When he saw Bob coming in, he didn''t stop talking, but just smiled at him.


    Bob also knew that he couldn''t provoke any of these people in the headquarters, so he stood aside and waited for the adults to finish talking.


    However, his eyes were fixed on the two soldiers who were surrounded by the big people. Their power armor sprayed with snow Digital Camouflage really made Bob jealous.

 Chapter 782

    After the headquarters received Chen Xin, Bob took his team members to form a battle formation and escorted Chen Xin to their stronghold.


    Different from the more casual way of advance when he came, Bob and his team members consciously undertook the escort task on the return trip because they wanted to protect Chen Xin, an important figure.


    Although in Bob''s opinion, the team of soldiers with more advanced equipment beside Chen Xin is enough to protect Chen Xin''s safety, Bob has not forgotten that they need to please Chen Xin.


    So Bob set out the battle formation used by the key guards in accordance with the code of conduct, carried out the task of protecting Chen Xin in accordance with the requirements of the code of conduct, and guided Chen Xin and his guard to the stronghold.


    Bob certainly walked a little slower than when they came back, but they returned to the stronghold very smoothly.


    Along the way, Chen Xin looked at the Bob team who was performing the requirements of the code of conduct, and his mood was happy.


    Although he also felt that Bob''s so-called protection was meaningless, he was satisfied with Bob''s serious attitude.


    In fact, unless the front defense line collapses, it is possible for alien creatures to cross the defense line, escape the surveillance of frigates and Falcon Titans patrolling in the sky and attack Chen Xin.


    At the same time, it is also necessary to break through the protection of a combat team equipped with power armor around Chen Xin and a Titan team with combat formation around Chen Xin, so as to really hurt Chen Xin under heavy protection.


    Under the multiple security system, the symbolic significance of Bob''s team is greater than the practical significance, that is to show their attention to Chen Xin.


    After entering the stronghold, the major who had been waiting for a long time hurriedly welcomed Chen Xin. He also asked the soldiers in the stronghold to line up to welcome Chen Xin.


    This made Chen Xin more or less unaccustomed. After a simple process, he asked the major to disperse the people.


    Because of the space in the stronghold, only the power armor team followed Chen Xin into the stronghold, while the Titan team stopped the body outside the stronghold and launched a protective formation.


    Bob, who returned to the stronghold, did not dissolve his team, but still let them follow the team around Chen Xin. At the same time, he also accompanied Chen Xin with the major and followed him to inspect the stronghold.


    The so-called inspection is actually to look around, find some problems and solve some problems.


    Under normal circumstances, what Chen Xin can see during his inspection should be arranged by the major and prepared for what he wants to see.


    But before coming, Chen Xin didn''t give notice in advance, which undoubtedly made the major have no time to prepare, and the time was only enough for them to simply clean up the stronghold, so as not to appear too dirty and messy, which made Chen Xin feel dissatisfied.


    However, even if it was temporarily cleaned up, the situation in this stronghold was not much better.


    This stronghold is a permanent fortification built of reinforced concrete. Although the defense is very strong, it is not very comfortable to live.


    In addition, a large number of soldiers live here, lack the conditions to take a bath, and the ventilation conditions of the stronghold itself are limited, so when Chen Xin walked into the soldiers'' living area


    He had to put on his protective suit and helmet again.


    "Sorry, sir, they are just some big soldiers who don''t understand the rules. Please forgive me." seeing Chen Xin put on his helmet again, the major undoubtedly felt very embarrassed. At the same time, he was also worried that Chen Xin was dissatisfied, so he hurried to apologize to him.


    The major himself didn''t wear a helmet. Of course, he could smell the smell of sweat accumulated around him for a long time because of lack of ventilation and neglect of bathing, as well as the foot smell emitted by soldiers baking their feet for warmth. It was an indescribable smell after fermentation.


    However, he himself has always lived here. He has been in abalone restaurants for a long time without smelling it. After getting used to it, he feels good.


    But obviously, Chen Xin can''t stand the taste.


    "Don''t you have the conditions to take a bath? You should pay more attention to personal hygiene?" Chen Xin was not angry, but asked with concern.


    While explaining to Chen Xin, the major did not forget to show his merit without trace: "sorry, sir, although there are bathing facilities in the stronghold, the conditions are limited. Our soldiers can only take a bath once a week. Everyone has to fight on the front line every day, so they are really sloppy."


    "Forget it, it''s not your fault. I''ll discuss with your superiors later to see how to improve your living conditions." Chen Xin didn''t delve into this problem, but he also knew that the living conditions of soldiers had a great impact on their combat effectiveness, so he planned to pay attention to it.


    Apart from the unacceptable sanitary environment, other problems in the stronghold are not so serious.


    Chen Xin turned around and was satisfied with his inspection.


    However, he did not leave immediately. Instead, he randomly found some soldiers in the stronghold and asked them some questions about life and their views on current weapons and equipment.


    Most of the soldiers'' life problems are still in heating and fresh food. Chen Xin has solved these two problems, so he has not gone too far on these two problems.


    However, Chen Xin is very interested in the problems reflected by these soldiers in terms of weapons and equipment.


    This stronghold receives a lot of equipment provided by Yanguo. The soldiers have basically used most of the equipment, including electromagnetic rifles, exoskeletons and power armor. In addition, it is the forefront of resisting alien invasion, so the soldiers also have their own views on these weapons and equipment.


    "The electromagnetic rifle is really easy to use, but the firing speed is a little too fast. Usually, 30 bullets in a magazine almost hit out with a trigger."


    "Exoskeletons are easy to use, but there are a few hangers. More ammunition hangers should be added to carry more ammunition."


    "All aspects of the power armor are very good, but there is a little air leakage. I hope it can increase the function of keeping warm and install other modules."


    "When the front line resists the attack of alien creatures, the main casualties are caused by flying units falling from the sky. The position needs an air defense weapon that can effectively resist air threats."


    Chen Xin recorded the opinions put forward by these soldiers one by one, intended to be used as a reference.


    After recording these, Chen Xin also looked at the major and asked him, "can the stronghold see the forward position? I want to have a close look at how the forward position fights."

 Chapter 783

    Although he came to inspect the position and really needed to know the operation of the front position, Chen Xin didn''t have any idea of going to the forefront trench.


    Climbing up the fire observation post of the stronghold and using a telescope, Chen Xin can directly overlook the whole position. He doesn''t need to run to the forefront of the position like a big soldier.


    The position inspected by Chen Xin looks like an inverted "human" shape. The front cross is the forefront trench to block the attack of alien creatures. Even if you stand at a stronghold at least one kilometer away, you can still clearly see the fire of soldiers and hear the fierce gunfire.


    At the back of a horizontal, two oblique trenches are not only the extension of the front trench, but also its fire supplement.


    More heavy firepower was obviously arranged on the two obliquely deployed trenches. Chen Xin even noticed that they also dug artillery positions between the two trenches, and arranged mortars and flattened anti-aircraft guns.


    However, looking at the appearance of those weapons, they should be old antiques pulled out of the warehouse. Most of them are from the cold war.


    But I have to say that these old guys are still very useful. At least in this battlefield, these weapons designed during the cold war have more advantages in lethality than modern weapons.


    This is not a retreat in science and technology, but a reduction in the power of modern weapons compared with those during the cold war.


    Modern weapons emphasize accuracy and effectiveness. They pay attention to one hit and destroy the enemy at the least cost, which is also determined by the form of modern war.


    But the weapons in the cold war period are different. Most of them are prepared for the possible three wars, more to meet the needs of large-scale war, and more emphasis on lethality and large-scale attack.


    So on this occasion, the old friends of the cold war really played better than modern weapons.


    After all, steel core bullets are much easier and cheaper than missiles to fight alien creatures. They are also large and full.


    Seeing that these cold war era weapons are now widely used, Chen Xin can''t help asking the major aside, "I see a lot of anti-aircraft guns arranged on the position. Are these old guys easy to use?"


    "It''s really easy to use. Flattening the anti-aircraft gun is very good for the lethality of alien creatures." the major nodded and explained to Chen Xin: "the firing speed of the old-fashioned anti-aircraft gun is not as fast as that of the modern anti-aircraft gun, but it''s a bit rather than a disadvantage now.


    After all, modern anti-aircraft guns may have fired hundreds of shells in a minute or two. Although the firepower is rapid, it can''t last. What we need now is firepower that can last and output stably. On this point, the old things are better used. "


    "I see. The output speed of modern anti-aircraft guns is really a little high." hearing what the major said, Chen Xin nodded slightly and wrote it down.


    Chen Xin did not pay attention to this problem. When he was in China, the military of Yanguo did not have any trouble in this regard. He felt that when the weapon firing speed was high, it could naturally be replaced with an anti-aircraft gun with low firing speed.


    In particular, the anti-aircraft gun is not the main weapon in the Dongting Lake defense line built by Yanguo. After all, the soldiers of Yanguo have a set of exoskeletons and heavy machine guns, and the firepower output brought by them is enough to meet the needs of the battlefield.


    In addition, there are no flying units of alien creatures in Yanguo, so there is no need for anti-aircraft guns to fight mosquitoes.


    However, as far as the European battlefield is concerned, it lacks the firepower configuration of ordinary soldiers with one heavy machine gun per person like Yanguo. They really need to use anti-aircraft guns as necessary firepower supplement.


    Although the electromagnetic rifle provided by Chen Xin solved the problem that ordinary soldiers could not cause damage to alien creatures, although the penetration of the electromagnetic rifle was sufficient, its lethality could only be said to be usable, not color.


    After all, in order to be compatible with European rifle bullets, electromagnetic rifles have some accommodation in caliber, and electromagnetic rifles mainly emphasize penetration. The killing caused by bullets themselves can only be said to have limited power for alien creatures.


    Therefore, in this battlefield, the tactics of flattening anti-aircraft guns to hit ground units have become extremely effective and practical.


    With those large caliber mortars, it constitutes the main heavy firepower strike force in the forward position, and it is also the main means of killing alien creatures in the European battlefield.


    As for more powerful and caliber firepower, it is the 155mm caliber howitzer attached to the stronghold.


    However, in order to protect the barrel and save shells, usually these guns will not fire. Only when the forward position is really unable to withstand, will they roar to support them and push back the attack of alien creatures.


    Only before receiving the support of Yanguo, even with these heavy howitzers, the front line of defense is often in urgent need. Only with the support of air strike forces can we stabilize the front line.


    Even several times, alien creatures broke through the first trench. It was only with the output of heavy firepower on the second trench and the timely support of the air force that they pushed the alien creatures back.


    However, more than half of the soldiers stationed on the position were killed.


    After that, this position encountered several similar situations, but later, with the fire support provided by Yanguo''s land ships and fighters, the losses were smaller and smaller each time.


    Recently, with powerful equipment such as electromagnetic rifles, exoskeletons and power armor, the combat effectiveness of the first trench has increased sharply. They have not been broken by alien creatures for a long time. Now even the situation of calling artillery fire support has become much less.


    It can be said that with the blessing of Chen Xin, their defense line is becoming more and more stable.


    But today, it seems that the attack of alien creatures is a little fierce, or they want to show it in front of Chen Xin, a big man. The soldiers in the forward position have called for artillery support for a long time.


    Because the weather was too cold, all the guns were closely protected, covered with thick thermal insulation blanket, in order to avoid freezing or other damage to the guns.


    After all, metal parts change in metal properties at a low temperature of tens of degrees below zero, but they are easy to be damaged.


    Now they got the order to use artillery support. The artillery ran out of the bunker of the stronghold, quickly lifted the insulation blanket covered on the artillery, quickly corrected the firing data and prepared for launch.


    At the same time, another group of artillery carried the shells to the gun position and completed the loading of the shells with the calibration of firing data.


    Refusing the major''s request to let him into the bunker, Chen Xin stood on the observation post and watched the artillery finish the launch preparation, then¡ª¡ª


    "Boom!" "boom! Boom!" "boom! Boom! Boom! Boom!" the God of war began his roar.

 Chapter 784

    After watching a heavy howitzer shelling from a close distance, Chen Xin finally returned to the land ship with satisfaction.


    "Send a class of power armor to the position I''ve been to. People''s hard reception and hospitality should always give some benefits." Chen Xin ordered the people around him after he came back.


    A class of power armor is naturally a generous gift, but for Chen Xin, it is just to let the 3D printing device print once.


    In fact, there are packed power armor on land ships. These power armor are reduced versions for European countries, and they are packed in the number of teams. They are originally used for the troops on the front line.


    Now separate a box, and it will not cause any impact.


    Chen Xin naturally has the authority to make such a decision. Therefore, after hearing his order, the people around him didn''t ask much. They just confirmed the quantity with Chen Xin, and then took a list for him to sign. After completing the formalities, they went to arrange helicopter delivery.


    "Academician Chen, what are the inspection results? Do you have any feelings?" the political work cadres saw Chen Xin coming back and came to him and asked.


    Chen Xin insisted on inspecting the defense line, which really made it difficult for political cadres to do. Fortunately, Chen Xin came back unharmed. He was relieved.


    "I can''t talk about my feelings, but I know a lot about the situation." Chen Xinchong''s political work cadre smiled. He didn''t have any ideas about the previous obstruction to himself. As he walked towards the bridge, he said: "The attack of alien creatures on the European battlefield is indeed more fierce than that at home. Although Europeans suffer from the loss of equipment, the number and types of alien creatures are stronger than those at home!


    To tell the truth, even if our soldiers are changed, they can do better in the face of such an attack, but their strength is limited, but they are not as embarrassed as them.


    When the quantity reaches a certain level enough to cause qualitative change, the quality of soldiers and the advancement of weapons are meaningless, and everything has evolved into a quality war. "


    "Quality war? Academician Chen, what do you mean?" suddenly heard a new term from Chen Xin''s mouth. Political cadres were a little more curious. At the same time, they also wanted to know how Chen Xin evaluated the defense war against alien creatures.


    "The so-called quality war means that the two sides are no longer fighting for industrial production capacity, the comprehensive quality of soldiers and the technological advancement of weapons, but simply competing for who can deliver more materials on the battlefield." Chen Xin explained to political cadres and gave special examples: "Just like the famous van fleet ammunition quantity during the war to resist US aggression and aid Korea, it already has the rudiment of a quality war. Although our ancestors withstood such fierce artillery fire, they have to admit that such firepower attack is effective.


    If any other army during World War II faced the amount of van fleet ammunition, it would collapse. Only our ancestors could withstand 70 fire attacks per square meter. "


    Hearing what Chen Xin said, the political cadres could understand Chen Xin more or less, so he asked Chen Xin, "but now, whether in the European battlefield or at home, the firepower delivery volume has not reached the standard of van fleet ammunition? Although alien creatures do have a tendency to pile us up with quantity."


    "So I say it''s a quality war!" Chen Xin smiled and was preparing to explain. He suddenly noticed the eagle Titan landing on the ship. He thought of one thing, so he stopped talking and walked over there.


    "Academician!" the pilot of the eagle Titan just got off the body and saw Chen Xin coming up, so he quickly stood at attention and saluted him.


    "Relax, let me ask you something." Chen Xin nodded and then asked, "did you notice the flying units of alien creatures when you were flying over the battlefield? Did you have contact with them? I''d like to hear your views on those flying units."


    Hearing Chen Xin''s question, the eagle''s pilot sorted his thoughts a little, and then answered, "I did see some flying units of alien creatures before, but they had been shot down by ground air defense fire before I came into contact with them, so there was no contact.


    However, judging from the pictures I observed, these flying creatures are about the same size as a fighter, with a wingspan of about 15 meters and a body length of more than 10 meters. Their body structure is somewhat similar to that of ancient pterosaurs or bats. I don''t see feathers. Their wings are skin membrane structure, which is similar to the Fengshen pterosaur in the age of dinosaurs as a whole.


    As for combat effectiveness, I can only say that flesh and blood can not resist air defense fire at all. Unless these flight units rely on a number of hard piles, it is difficult to break through the air defense network on the previous position. "


    "Really? The information you said is very important. I wrote it down." Chen Xin nodded and recorded the information the pilot said. Then he asked him, "if you are asked to catch an alien flying unit back, do you think the eagle can catch it?"


    "This..." facing Chen Xin''s problem, the driver hesitated and dared not promise.


    "There are difficulties? Tell me, I''ll find a way to see if it can be solved." Chen Xin looked at the driver''s hesitation, just smiled and didn''t care.


    Hearing what Chen Xin said, the pilot bit his teeth and replied to Chen Xin, "if it''s a flying unit that kills alien creatures, the eagle has no problem at all, but I lack the necessary air capture means, so I can only kill it and bring it back."


    "Can only be killed and brought back? I see. It''s really hard to catch alive in the air." Chen Xin nodded understandably, turned and looked at the eagle Titan parked aside.


    This Titan was built by Chen Xin himself. Naturally, he is also very familiar with it. All the designs are familiar with his chest. Chen Xin clearly knows that there is only a pair of power claws for close combat on the eagle. The flying unit used to tear apart alien creatures will be very easy to use. It can even be used to cut the turret of a tank, but it is really difficult for the pilot to catch living creatures.


    "OK, I see. If you can, get some complete bodies back." Chen Xin gave up the idea of letting the driver catch some live bodies and asked him to get some more complete bodies back.


    Seeing that Chen Xin changed his mind, the driver quickly agreed with a sigh of relief.

 Chapter 785

    After arranging people to capture alien creatures that have never appeared in China on the European battlefield, Chen Xin calmed down to think about how to strengthen the combat capability of the front-line forces.


    Although the result of this inspection is that the front-line troops have been able to resist the attack of alien creatures and have shown a certain calm, this does not mean that they do not need to enhance their combat capability.


    During his stay in Europe in recent months, although Chen Xin is not very able to obtain domestic information, there will still be briefings in China every week, and the instant messaging is smooth, and he knows all the information he should know.


    The Dongting Lake theater has now turned from defensive to offensive. Although the offensive is not strong, several attacks have not achieved results and have been repulsed by alien creatures, it is obvious that the offensive and defensive has been easy.


    Relying on land-based ships and mobile bases as strategic support, Titans and power armored forces as key offensive forces, even ordinary soldiers also have exoskeletons, carry heavy machine guns and jet backpacks to ensure firepower and mobility. The combat capability of the Yanguo army has formed a considerable generation gap with European countries.


    Although Europe has also begun to equip power armor and exoskeleton, there is a big gap between Europe and Japan in terms of the number of equipment and the application ideas of equipment.


    Although Europe, relying on the support of inflammatory countries, has gradually changed from being shaky to being able to support and resist the attack of alien creatures, it is clear that just being able to resist the attack of alien creatures is far from enough.


    Human beings will fight back and must fight back, because this is human''s home and cannot be occupied by alien creatures.


    If it is only to isolate disasters, the United States and European countries have actually done so.


    Relying on the strong defense line and the fighting of the army, they have blocked the disaster of alien invasion.


    Although this will bring huge military expenditure and mankind must spend a lot of effective power to resist the attack of alien creatures, blocking is blocking after all.


    For some people who are not so enterprising and responsible and just want to maintain the status quo, this is enough.


    After all, they don''t have so many ideas. They can maintain their current life and won''t be affected. As for how human beings and civilian life are, they are never within the concern of those big people.


    Perhaps some people will try to turn this war into a so-called sustainable war, so as to obtain a steady stream of benefits and benefits, but this is harmful to mankind.


    In the eyes of real people of insight, we must not do so.


    Chen Xin did not have such an idea, nor did the senior leaders of Yanguo.


    In their eyes, construction and development are what they need. They will not consider and choose to obtain private interests by relying on continuous war to damage the interests of the country and even the whole mankind.


    This is also why the army of Yanguo launched a counterattack with an almost impatient attitude just after it had the ability to counterattack.


    Because from the high-level point of view, the war with alien creatures has seriously slowed down the road of national construction and development, and more seriously affected people''s production and life. If these alien creatures are solved one day earlier, the country can return its energy and resources to construction and development one day earlier.


    Even if such a hasty attack may bring some unnecessary losses, these losses are within the tolerable range compared with the consumption brought by the current state of war.


    However, when the inflammatory country was ready to counter attack, the European side had just got rid of the situation of being beaten passively, took a breath and was able to deal with the attack of alien creatures.


    Although there is Chen Xin, who helps the country open, it has to be said that the situation in Europe is really a mess.


    If it had not been for the hard work of Chen Xin and the European aid fleet during this period, coupled with the strong assistance of China, the European side would not have recovered in such a short time.


    Therefore, it is unrealistic to hope that Europe will have the ability to counter attack in a short time.


    If we take the three stages divided by the founder of Yanguo in on the protracted war, Yanguo has entered the stage of strategic counterattack, but Europe has just changed from strategic defense to strategic stalemate.


    During this period, Europe should try its best to accumulate strength for the counter offensive.


    It is for this reason that Chen Xin will vigorously rectify the chaotic order in Europe and establish a practical and effective security maintenance system, as well as organizations such as militias and knights, which can be regarded as reserve forces, so as to cultivate sufficient reserve forces for Europe.


    In this way, when Europe turns to the stage of strategic counter offensive, it can quickly arm itself and put enough troops into the counter offensive.


    But if we want to counter attack, it is not enough to rely solely on reserve forces.


    Although the resource output of Europe has recovered a lot, coupled with the efforts of the European aid fleet to ensure the consumption of the front line and the living needs of the people, it is careless, but it is obvious that this can not accumulate resources for the counter offensive.


    In order for Europe to accumulate strength for strategic counterattack, in addition to increasing the existing resource output as much as possible and making the output greater than the consumption, it also needs to reduce the existing consumption as much as possible.


    Although the consumption of people''s living materials can not be reduced, in fact, this part is often squeezed to the limit first during the war.


    Although Chen Xin is very reluctant, he has to admit that even if the material production situation improves, the living conditions of people in Europe will not be improved in a short time.


    Although countries have limited control over their own countries, and autonomous cities can be called out of their control, they can squeeze the bottom people and obtain more resources as much as possible.


    Even those autonomous cities are the same. After all, the key point that they are not regarded as hostile forces by the military of various countries is that they are still paying taxes to the officials of various countries.


    As long as a little tax increase is tolerated by the autonomous cities, they can be squeezed continuously. As long as it is controlled to a degree that will not cause the rebound of the autonomous cities, there will be no problem.


    Therefore, if Chen Xin wants to reduce the existing consumption, he can only think of ways from the front line.


    How to reduce consumption as much as possible without weakening or even improving the front-line combat effectiveness is what Chen Xin needs to consider.

 Chapter 786

    The so-called quality war is a way of war in which the belligerents throw more quality materials into the battlefield in as many ways as possible.


    Because in such a war, the quality of weapons and equipment, the quality of soldiers, and even tactics and Strategies of both sides have no impact on the outcome of the war.


    Even the outcome of one or more battles cannot affect the outcome of the whole war. If we cannot form a quality advantage on the battlefield and cut off the other party''s material delivery to the battlefield, we will not win.


    It can be called the ultimate embodiment of the impact of logistics on war.


    At this point, aliens already have all the characteristics of this mode of war.


    How many individuals of alien creatures human beings have annihilated has no impact on alien creatures. There is neither a decline in the quality of soldiers nor a collapse in morale, nor a decline in the combat capability of troops after the depletion of technical weapons.


    Some are just endless, as if they are massive descendants used to consume human bullets, like the flood of the mountain tsunami, trying to submerge human positions and defense lines.


    This is a quality war. There is no need to worry about the gap between the combat effectiveness of both sides, nor do we need to consider any tactics and strategies. As long as the other side''s elimination speed is not as fast as the rear side''s delivery of materials to the battlefield, it can''t stop the offensive.


    As for whether the weapons are advanced or not, whether the soldiers are brave or not, and whether the tactics and strategies are effective, they are meaningless.


    Because you worked hard to annihilate a large army. When celebrating the victory, the rear may have sent ten times the number of new troops you annihilated into the battlefield.


    Even if you can continue to win, each time is a great victory and can wipe out a large number of enemies, as long as you destroy faster than the enemy, you will still be submerged in the end.


    Even before you are overwhelmed by the number, you have lost your combat effectiveness due to the consumption of ammunition, the wear and tear of weapons, and even the loss of personnel.


    At this point, alien creatures have proved this with their breeding speed faster than that of human bullets. If they don''t kill fast enough, they will really be stacked to death.


    But aliens can fight quality wars, but humans can''t.


    Although there is a trend of quality war on the front line, which is faster than the speed of human throwing steel into the battlefield or the speed of alien creatures throwing biomass into the battlefield, human beings do not have the capital to carry out quality war.


    Chen Xin has studied the mother of those alien creatures responsible for breeding offspring, which is an efficient fertility machine that can directly obtain energy and material from magma.


    Relying on the endless magma and geothermal energy under the blue star, the resources of alien organisms can be regarded as infinite. The only thing that restricts their breeding speed and production quantity is their speed of obtaining energy.


    In Yanguo, because alien creatures are limited to the battlefield of Dongting Lake, their access to energy and material is limited. This is why the number has been limited and can not break through the defense line of Yanguo military. Now they are being counterattacked.


    But Europe is different. The alien creatures that have spread throughout the Mediterranean Sea do not have the restriction of obtaining energy and material, which leads to their seamless attack like tide along the whole Mediterranean coast.


    In the long defense line, tens of thousands of tons of bullets are fired every day, not to mention the consumption of a large number of shells, missiles and other explosives.


    It can be said that all the time, this line of defense is like a bottomless pit, constantly swallowing up a large amount of materials to fight against the tide of alien creatures.


    Human beings can''t afford such consumption.


    After all, the mines will dry up one day, and the oil wells will dry up eventually. No matter how many troops there are, they can''t afford to be consumed.


    It takes 16 years to raise a generation and train it to the point where it can go to war, but what about aliens? They grow operational progeny even faster than humans produce bullets.


    Therefore, for Chen Xin, how to maximize the efficiency of every bullet and gram of steel to kill alien creatures and make a good enough exchange ratio has become the focus he needs to consider.


    After all, in the quality war, in addition to having a stronger quality delivery ability than the opponent, there is only how to make more efficient use of the quality in their hands.


    Alien creatures can achieve the reuse of materials by recycling biomass on the battlefield, but humans do not have such an advantage. They can only improve the exchange ratio between each gram of material and their opponents as much as possible, and kill the most enemies with the least consumption.


    For humans, this is not impossible.


    After all, the talent of human beings in killing is too strong. It can be said that human beings have been particularly good at killing and destruction since their birth.


    Throughout the history of mankind, it is a history about how to kill and war, and mankind has been studying how to kill more efficiently.


    In the age of cold weapons, there may still be efficiency problems. No matter how brave a person is, he can kill so many enemies.


    But in the era of hot weapons, one button can easily kill tens of thousands, hundreds of thousands, or even millions of people.


    The mass energy conversion formula not only explains the relationship between matter and energy, but also brings human beings with weapons that can easily destroy themselves.


    However, Chen Xin does not intend to use a nuclear bomb.


    On the one hand, the nuclear bomb has a great impact, which is not only a problem of environmental pollution, but also a problem of the sustainability of killing.


    What Chen Xin needs is to reduce the overall consumption and reduce the pressure on rear logistics and production. Using nuclear weapons does save trouble, but it can not reduce the material consumption of ordinary soldiers.


    Just like modern anti-aircraft guns and old-fashioned anti-aircraft guns during the cold war, the front line now prefers to use old-fashioned anti-aircraft guns, because the firing speed of old-fashioned anti-aircraft guns is slower and the ammunition consumption is not so large.


    After all, the current situation on the front line is the same as the overall situation in Europe. They can get limited ammunition supplies per unit time, so they can''t open up to fight.


    If modern anti-aircraft guns are used, the firing speed of thousands of rounds a minute is really cool, but it is not designed to kill ground units. Hundreds of shells may not last a minute, which is very undesirable in today''s battlefield where there is no pause in combat time.


    The old anti-aircraft guns perform better at this point. After all, the firing speed is only a few hundred rounds a minute. As long as you control it a little, don''t press the trigger and don''t let go. All the bullets are fired at once, and hundreds of shells are enough to support a short period of time.


    Therefore, for Chen Xin, what he has to do is to reduce the firing speed of the current weapon and improve the power of the weapon.

 Chapter 787

    "Reduce weapon firing speed and increase weapon damage? Isn''t this changing the assault rifle back to the old rifle?" listening to Chen Xin explain his ideas, the political cadres he brought to discuss couldn''t help thinking of the old rifle.


    Hearing this, Chen Xin smiled: "it''s normal. Isn''t the war between us and alien creatures like the trench war on the battlefield of World War I? However, the intensity of our war is much more intense than that of World War I. whether it''s steel delivered or materials consumed, it''s much more than that of the two world wars combined.


    You know what? Now the front line consumes a large amount of materials and ammunition every day. It''s only the defense line I visited last time. Their three battalions have to destroy a ton of ammunition in an hour, which is only the consumption of ordinary soldiers.


    As for the ammunition consumed by explosives and rear artillery support, although there is not so much, there is not much less. The ammunition consumed by the whole defense line at all times can only be calculated in 10000 tons.


    So even if I just reduce the firing speed of my rifle by one shot per minute, the ammunition I can save is an extremely huge number. "


    "But having said that, it''s too much work to replace the equipment of the whole front line, and the investment will not be small." the political work cadres only estimated a little and knew that this is by no means an easy job to complete.


    Chen Xin also agreed with this. He nodded and said, "so I don''t intend to solve the problem at one time, and dressing up is a step-by-step thing. Even during World War II, new equipment emerged one after another in various countries. Can''t many weapons developed in the middle of the war be generally equipped with troops until the later stage of the war or even near the end of the war?"


    Hearing what Chen Xin said, the political work cadre nodded reassuringly. Although he did not stop Chen Xin''s power, he could still persuade Chen Xin about his possible disorderly ideas.


    Since Chen Xin doesn''t have the idea of fooling around, he naturally won''t talk much.


    "Academician Chen, what are you going to do? Do you have any specific plans?" the political work cadres asked Chen Xin curiously.


    Chen Xin thought for a moment and said, "there is no good idea in a short time. I intend to start with the electromagnetic rifle we are equipping the troops of European countries. This is the weapon we are changing. We can see the effect intuitively."


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    A small land ship carrying supplies gradually landed, and the officers who had been waiting for a long time on the ground rushed to meet them with people.


    With the door of the land ship opened, several staff of Yanguo came down from it.


    "Hello, I''m major Marvin, the commander of the XX stronghold of the XXX defense line. I was ordered to receive materials." the officer took out a document from him, handed it to the staff of Yanguo, and explained it to him. His attitude was very respectful, even with a trace of flattery.


    No wonder major Marvin has such an attitude. Because of the remote location of his troops, so far his troops are still using the old equipment and do not enjoy the welfare of replacing the new equipment provided by Yanguo.


    It''s not easy for his troops to receive materials and change new equipment this time. Major Marvin is very excited. Naturally, he also wants to please the staff of Yanguo and strive for better welfare for his troops.


    Although it is not the turn to replace the equipment provided by Yanguo, major Marvin has long heard that Yanguo people will provide better weapons and equipment and better logistics supplies. If they can get more supplies from them, let alone flatter them, even if major marwen asks Yanguo people''s father in front of him, he will not refuse.


    Of course, the staff of Yanguo didn''t have the special hobby of asking people to call their father. After receiving the supporting documents handed over by major Marvin and checking them with the list in their hand, the staff member asked people to start carrying materials.


    "According to the figures on the list, the equipment is electromagnetic rifles and exoskeletons of three battalions, as well as a platoon of power armor and a company of new high-level dual-purpose guns." the staff showed major Marvin the list in hand and explained the quantity of materials to him: "You can get ammunition of two cardinal numbers and one regiment''s standard weekly supplies. I won''t read what''s in it. You can look at the list yourself. Everything is packed. You can count the quantity."


    Hearing the staff say so, major Marvin said thank you and hurriedly asked the people he brought to help count the quantity of these materials, while he accompanied the staff, hoping to bring closer the relationship.


    "This batch of electromagnetic rifles is a new modification, and their firing power is improved compared with the previous models. Like the previous models, they can be compatible with the NATO ammunition you are currently equipped with. However, because this type of electromagnetic rifle reduces the firing speed, it is recommended to use it with the new ammunition." The staff didn''t care much about major Marvin''s relationship, but explained the equipment to him.


    Major Marvin heard that the firing rate of this electromagnetic rifle was reduced, but he didn''t think there was anything wrong, even thought it was a good thing.


    Major Marvin was particularly concerned about the consumption of ammunition because his troops had not been changed for a long time. In addition, the garrison was far away from the supply point, and the supply delivery was often delayed.


    In fact, even though the fighting is very fierce, in order to save ammunition, major Marvin''s troops also fight by firing three bursts as much as possible, rather than holding the trigger and hitting one magazine directly.


    After all, holding the trigger to empty the magazine directly is very cool, and the killing effect is also very good, but it consumes too much ammunition.


    For major Marvin''s troops, which are not necessarily delivered on time, every bullet needs to be saved.


    Therefore, major Marvin thought it was good for the firing speed of electromagnetic rifle.


    "What is the firing rate of this electromagnetic rifle?" major Marvin asked curiously. According to his estimation, in fact, the firing rate of 300 to 400 rounds a minute is an ideal firing rate, which can not only ensure the firepower, but also reduce the consumption of ammunition to a more acceptable level.


    The answer given by the staff did not exceed major Marvin''s expectation: "the firing speed of this electromagnetic rifle is 350 rounds per minute. There are three shooting methods, single shot, three consecutive shots and consecutive shots. The magazine can hold 40 bullets."

 Chapter 788

    Although the new slow fire electromagnetic rifle was quickly distributed to the army and quickly reduced ammunition consumption, it is obvious that Chen Xin will not be satisfied with it.


    The bullets that can be saved by reducing the firing speed of electromagnetic rifles are mainly those that are fired more when holding the trigger. For example, some elite veterans or soldiers with enough experience will adjust the firing speed to three bursts to save ammunition.


    Therefore, although relying on the huge base, the ammunition consumption of the new electromagnetic rifle is quickly reduced after loading, on the whole, the proportion of the reduced part in the whole logistics consumption is not much.


    Compared with the whole defense line shooting tens of thousands of tons of ammunition every minute, saving one or two rounds of ammunition each time is really not so remarkable.


    So Chen Xin soon turned his attention to other aspects.


    In addition to electromagnetic rifles, Chen Xin is most concerned about the anti-aircraft guns widely used in the front line, or anti-aircraft and flat dual-purpose guns.


    This small caliber rapid fire gun was originally used for air defense, but after it was leveled in World War II, it was used to fight infantry and destroy vehicles such as tanks, and achieved good results. Therefore, this weapon was also designed to attack the ground.


    When this weapon is in the air, it mainly relies on the formation of a barrage at high firing speed to block the aircraft, because it needs to form a barrage, and the natural firing speed must be very fast.


    Especially with the progress of modern military science and technology, when the jet aircraft flies higher and higher, the anti-aircraft gun is basically unable to hit, so it is more used to shoot UAVs and ground attack missiles.


    Therefore, the requirement of shooting speed is higher and higher.


    In the past, this was naturally a very correct idea, but now it is a waste.


    After all, you can destroy the enemy with three or five shells. As a result, because the firing speed is too fast, you can shoot out more than ten or twenty shells at once, which is a complete excess of vitality.


    Although there is no gap when alien creatures attack, even if they keep shooting in one direction with their eyes closed, they can constantly destroy the enemy, but too high fire speed will still hit the same target many times, resulting in excess firepower.


    Before the assistance of Yanguo, these dual-purpose guns were the main weapons that could effectively kill alien organisms on the battlefield. Therefore, a large number of such weapons were deployed on the whole defense line, and the small caliber shells they used were also the largest part of ammunition consumption.


    If this part of consumption can be reduced, Chen Xin believes that it is very meaningful to reduce logistics pressure and resource consumption.


    Just when Chen Xin tried this, there was news in China, and the high-level ordered him to finish his work in Europe and return to China as soon as possible.


    "What happened? Why did China suddenly want me to return home?" Chen Xin frowned when he came to inform his political cadres.


    "Academician Chen, you have been in Europe for almost a year, and the domestic side has always had the idea of allowing you to return home." facing Chen Xin''s inquiry, the political work cadres hurriedly explained to him: "this time the country hopes you will return home as soon as possible, because the military has turned into the stage of comprehensive counter offensive, and the country needs you, so it will let you return home as soon as possible."


    Of course, the reasons given by political cadres are very reasonable. After all, Chen Xin still has a lot of work in China. Staying in Europe for a long time has delayed many of his work in China.


    If the war situation in Europe had not stabilized, I''m afraid China would have wanted to transfer Chen Xin back.


    At present, the situation in Europe has gradually improved and everything has stabilized. Although it is far from the situation in which the domestic counterattack can be carried out, at the beginning, what the domestic want is to enable the European side to maintain the defense line and not completely collapse.


    Even when Chen xinlai came, both China and Lucia were building defense lines in Eastern Europe to prevent Europe from continuing to resist the attack of alien creatures after the total collapse of Europe.


    When Chen Xin came to Europe at that time, the minimum goal given to him at home was to support the European defense line until the construction of the Eastern European defense line was completed.


    Now, Chen Xin has overfulfilled the task, not only making the European defense line stick to the completion of the construction of the Eastern European defense line, but also stabilizing the whole European order, improving the situation in all aspects, and turning the defense line from precarious to safe.


    In the absence of accidents, there is no doubt that there will be a total collapse.


    Even the Black Sea area, which Chen Xin had been worried about before, has now established a solid defense line, blocking the possibility of alien breakthrough from here.


    Even for the European aid fleet, a large number of materials are transported back to China every week, raising the number of cargo land ships on this route from three to seven, almost one shift a day.


    Therefore, it is not very strange for the domestic side to recall Chen Xin at this time.


    But Chen Xin still heard some problems from the words of political cadres, so he asked them, "is there something wrong with the domestic counter offensive?"


    This is what Chen Xin has been worried about.


    Since he learned that the domestic counter offensive had been launched, Chen Xin has always paid attention to this matter. Although he has not received relevant information about major problems, there are small problems such as poor offensive and unnecessary losses caused by insufficient preparation in the process of counter offensive.


    Chen Xin is not very worried about these small problems. Since the country is ready to counterattack, it has naturally made plans for these problems.


    Moreover, in terms of the current strength of Yanguo, these small problems are within the scope that the country can bear.


    Exposing the problems will help solve the problems, adjust them in time and avoid bigger problems.


    But that doesn''t mean there are no other hidden dangers.


    You know, the biggest problem with alien creatures is that they are deep underground. What is revealed on the ground is only cannon fodder that is not important to them.


    It is really not difficult for human beings to clear up the alien creatures on the ground, but in order to completely eliminate the threat posed by these alien creatures and completely eradicate them, we must go deep into the underground.


    This part is what Chen Xin is most worried about, because mankind has not really designed weapons for use in underground caves so far.


    And there is no experience of large-scale operations in this environment.


    Whether we can achieve the desired results is a very unknown thing.


    It is precisely out of concern about this that Chen Xin handed over the work at hand after thinking for a while, and then left for home.

 Chapter 789

    Chen Xin returned home very quickly. After he handed over all his work, the land ship returned with his usual route.


    At present, this route has become an important material transportation route between Europe, Yanguo and Lucia. Resources from Europe will be imported into Yanguo through this route, and various materials produced in Yanguo will also be transported to Europe through this route.


    As an intermediate node, Lucia has also obtained great benefits by virtue of the advantages of communicating the products of the two places and its own material production.


    In particular, Lucia also needs to build a defense line in Eastern Europe. A large number of materials gather in Lucia. The construction of the defense line also requires a lot of human and material resources. With the support of Japan and Europe, it has greatly promoted the local prosperity of a wave of Lucia.


    This also led to the fact that when Chen Xin returned home, not only the Eastern European defense line had been completely built, but also fortified at several main nodes, which was majestic when viewed from the air.


    "This defense line looks much stronger than the European defense line." still standing on the lookout platform outside the bridge, Chen Xin sighed at the brightly lit Eastern European defense line below.


    "This is academician Chen. Your work in Europe has won them time to build a defense line and fortify it." the political work cadres explained to Chen Xin with compliments: "if academician Chen hadn''t stabilized the European defense line, I''m afraid you would be building a fortress while fighting."


    For the compliment of political cadres, Chen Xin just smiled and said, "isn''t that what I want to do when I come to Europe to prevent the whole Europe from becoming a battlefield?"


    After laughing, overlooking the earth from the sky and looking at the endless defense line under his feet, Chen Xin couldn''t help feeling a sense of pride because he had contributed to the establishment of this defense line.


    Looking at this magnificent defense line established under their own influence, how can people not be proud and filled with emotion?


    "There are 37 large fortresses in the whole Eastern European defense line. The whole defense line is based on these 37 large fortresses and is divided into 37 different jurisdictions. Each large fortress will set up several small fortresses as strategic support according to the jurisdiction." seeing Chen Xin looking at the defense line under his feet, the political cadres were lucky to simply introduce him: "Each small fortress is built with a structure similar to the Suo fort, which incorporates all the defense structures that can be used in the urban defense era, while the defense line outside the fortress is built with reference to the experience of trench construction during World War I and World War II.


    In addition to the trenches used to allow soldiers and the enemy to fight head-on, there are a series of preset heavy machine guns and dual-purpose artillery fire points, artillery positions, tank attack positions, underground traffic ditches, underground barracks, ammunition depots and other facilities. It can be said that the defense capacity is several times that of the European defense line. In terms of the attack intensity encountered by the European defense line, it is absolutely impossible to break through this defense line! "


    Hearing the introduction and evaluation of political cadres, Chen Xin is also very satisfied with the line of defense in front of him.


    Although human beings do not have the powerful body and terrible reproductive ability of alien creatures, nor the strong vitality that can invade species across galaxies, human beings have their own strength.


    We can build our home with our own hands, and we can build a solid defense line with unity.


    Thinking of these, Chen Xin suddenly became full of confidence in the complete elimination of alien creatures.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    It is still Stalingrad that I came to last time. As the middle point of the whole route, land ships between China and Europe will choose to make some supplies here.


    Chen Xin is the same with them. The land ship landed on a specially built berth.


    Because there are land ships going back and forth on this route every day. While the route becomes busy, their supply business here also becomes more.


    So the lucians built special berths for land ships to facilitate their loading and unloading of goods and replenishment.


    "It seems that the city is much better than when we came last time. If I could look like what I am now, maybe I would like to visit the city." Chen Xin looked at Stalingrad in front of him and joked to the political cadres on the side.


    For Chen Xin''s joke, political cadres also smiled and said, "academician Chen, if you want to go to the city, we can stay here for a day."


    "Forget it, there''s no need. Since China is anxious to call me back, don''t waste time." Chen Xin smiled and shook his head and refused, but still looked at the city in front of him, with an inexplicable longing.


    This is not the yearning for this city, but the yearning for human urban life before the disaster.


    In front of the city, the street lights are on, the snow on the street seems to have been cleaned, there are lights in the buildings, and there are pedestrians and vehicles on the streets. Although it seems that many places are still covered with snow, you can feel the strong breath of life.


    The city is alive, it is emitting vitality, it is a city full of vitality.


    "It''s really beautiful!" Chen Xin sighed and said with emotion to the political cadres: "don''t you think? A city full of vitality and vitality still stands up from the ruins even after the disaster!"


    "This is really beautiful!" the political work cadres sincerely agreed with Chen Xin.


    Stalingrad in front of us, if we only look at it from the appearance, we can''t talk about how beautiful and beautiful it is. After all, there are only street lights and lights from the windows in the city at night, which is far from those beautiful cities before the disaster.


    But the scenery in front of us is also beautiful, because it is the fuel of human civilization.


    "I don''t know what happened to the domestic construction in the year I left?" Chen Xin sighed for a while and turned to discuss the domestic problems with political work Cadres: "a lot of resources are transferred to military production, but also to support the construction of European battlefields and Eastern European defense lines. I''m afraid the domestic construction will be delayed a lot?"


    Because Chen Xin has been with him for almost the whole year, he has only read some briefings on the domestic situation, so he can only guess and answer: "the domestic construction should not be affected much? This will not be taken into account above.


    Moreover, in the briefing from home, there are also reports on the achievements of domestic construction. I believe they must have achieved commendable results in this year.


    Even Stalingrad of the Lucian people looks like this. How can China be worse than this? "


    "That''s right. Let''s go home early and see what China looks like earlier!" Chen Xin smiled.

 Chapter 790

    "Didi! Didi! Didi!" in the morning, the sound of the alarm clock woke Chen Xin up from his sleep.


    However, when Chen Xin woke up, he just stretched out an arm and patted on the alarm clock at the head of the bed. After pressing and stopping the alarm clock, he retracted his arm and hugged the soft body in his arms.


    "Ah Xin, it''s time to get up." Mo Qingyan, who was held in Chen Xin''s arms, whispered to him.


    After nearly a year, Chen Xinjiu returned home yesterday. Mo Qingyan and Qin LAN were naturally very happy about his return, so some things that men dream of naturally happened.


    In the morning, Qin LAN got up early because she had work to do. She got up early and went to work.


    However, when she got up, Mo Qingyan also woke up. She just worried about Chen Xin who was still sleeping, so she didn''t wake him up. She was still held in his arms and continued to sleep.


    Being held in her arms by Chen Xin and waking up together in the morning is a very reassuring and happy thing for Mo Qingyan.


    Her beloved came back after a year. She also wanted to have more time to be gentle with Chen Xin instead of calling him to work early in the morning.


    The time on the alarm clock is getting late. If you don''t get up again, Chen Xin''s parents will have bad ideas.


    Although she and Qin LAN are actually the default daughter-in-law of Chen Xin''s parents, some things will still make people feel shy and embarrassed in front of their parents.


    So Mo Qingyan still stretched out her small hand, gently pushed Chen Xin''s chest twice and said to him, "get up! The sun is drying your ass! If you don''t get up, people will get up!"


    Although Qin LAN had kindly helped close the shading curtains when she left, Mo Qingyan could still feel the sunshine coming in from the window.


    After returning to the sunshine for a long time, Mo Qingyan''s sleep has been in a very good state. Every morning when the sun shines into the room, she will wake up. Today, if she wasn''t to accompany Chen Xin, she also got up early.


    However, Chen Xin, who was pushed twice by Mo Qingyan, just held her tighter, rolled over and pressed her, and then muttered, "let me sleep again..."


    "Ah Xin!" when Chen Xin pressed her down, Mo Qingyan felt helpless. After struggling for nothing, Mo Qingyan could only let it go.


    Although she knew that Chen Xin was just playing tricks, Mo Qingyan connived at some of his little willfulness when she thought that Chen Xin had not seen him for a year.


    Otherwise, she and Qin LAN wouldn''t have stayed with him last night.


    You know, when Chen Xin went to Europe, she and Qin LAN had their own jobs and lived in their own places. They didn''t live with Chen Xin''s parents.


    On the one hand, Chen Xin is not at home. It doesn''t seem justifiable for them to live in Chen Xin''s house. After all, it doesn''t look like they were in the shelter built by Chen Xin himself.


    So usually, Mo Qingyan and Qin LAN take turns to accompany Chen Xin''s parents for dinner. Occasionally, they stay at the request of Chen Xin''s parents, but they hardly stay. Most of the time, they leave after dinner with the two old people.


    But Chen Xin came back from Europe yesterday. They haven''t seen Chen Xin for a long time. They have a lot to say to him, so they both stayed and slept together at night.


    It is precisely because Chen Xin came back after such a long interval that Mo Qingyan connived at Chen Xin. Even if she was pressed to get up, she would be late for today''s work.


    However, when Mo Qingyan was thinking about how to ask for leave later, Chen Xin kissed her on the forehead and let her go.


    "Ah Xin? What''s the matter? Don''t you sleep more?" seeing Chen Xin who let go of himself and sat up from the bed, Qin LAN immediately looked at him curiously. He didn''t understand why Chen Xin, who was just waiting for bed, got up so directly.


    "You have to get up and work! The leader will see me today! You can''t stay in bed at home?" Chen Xin kissed Mo Qingyan again. Then he got up and walked to the bathroom. When he came to the bathroom door, he looked back at Mo Qingyan who had sat up from bed: "Qing Yan, I want to take a bath. Do you want to take a bath together?"


    "Well, but don''t be bad!" Mo Qingyan glanced at the alarm clock and saw that it was still time to take a bath, so she nodded and agreed.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "Good morning, academician Chen, are you back from Europe?" a staff member saw Chen Xin appear and hurriedly greeted him, as if surprised at his return.


    Chen Xin also greeted the staff member, nodded and said, "I came back yesterday. How''s my work recently?"


    "It''s terrible. Without academician Chen, our research progress has been slowed down by at least 500%!" the staff member exaggerated. Of course, what he said was just a joke, but there is no doubt that the lack of Chen Xin has indeed reduced the efficiency of the whole organization.


    Hearing this joke from the staff, Chen Xin just smiled. Although he didn''t take it seriously, he still smiled at him and said, "well, when I go to have a meeting with the leaders first, you can ask people to sort out the problems accumulated by various departments during this period, and deal with them after I finish the meeting."


    "Yes, academician!" when the staff heard Chen Xin say so, they also put away their smiling face and nodded quickly and seriously.


    Looking at the staff member hurried to perform the task assigned by him, Chen Xin habitually shook his head, and then went upstairs to his office.


    After a year, I didn''t come back. Although the office is still clean and tidy, it seems cold and unpopular.


    He opened his chair and sat down. He looked at the office he had not seen for a long time. After a little adjustment, Chen Xin opened the conference system on the table and waited for a meeting with senior leaders.


    So far, he doesn''t know why the top management is eager to call him back. That''s why he got up so directly from the gentle village today. He urgently wants to know what happened.


    If something serious happens, he must be prepared. After all, although the situation seems to be very good, if something goes wrong, it will soon make all this disappear.


    Preventing bad things from happening is what Chen Xin hopes to do.


    Chen Xin suddenly felt that maybe he should prepare some plans or backup plans like a rich and young victim of paranoia?


    With this in mind, when Chen Xin thought about these, the conference equipment in front of him lit up and the senior leaders went online one by one.

 Chapter 791

    In a laboratory, Chen Xinzheng and a group of researchers wore goggles and watched the experiment in front of them.


    A device that looks like a cannon is placed in the center of the laboratory, and on the other side, about ten meters away from it, there is a shelf on which is the shell of a cut combat daughter.


    "No. 3 experimental laser irradiation weapon, the 12th damage test, the target combat daughter''s back armor, the purpose of the experiment is to test the damage effect of laser irradiation weapon on alien organisms." a researcher read today''s test project according to the regulations, and then asked Chen Xin for instructions: "academician, can we start the test?"


    Looking at the experimental laser weapon in front of him, Chen Xin nodded with expectation: "let''s start."


    "The experiment begins!" the researcher announced loudly and then pressed the button on the side console.


    The angle of the laser weapon itself has already been adjusted, and there will be no deflection problem, so just press the switch to "launch" the laser weapon.


    With the press of the button, a not clearly visible light hit the shell in front, which burned in just a moment, producing a large amount of smoke and making the lavender laser visible to the naked eye.


    The irradiation lasted about three to five seconds, the researchers stopped the irradiation, and a scorched mark was etched on the target''s shell.


    Chen Xin asked the researchers around him to take the target, while he himself went to the laser weapon and looked at the laser weapon made by these researchers using the abundant energy brought by the nuclear battery during his absence.


    In fact, there has always been research on laser weapons. Countries have put forward this concept as early as last century and carried out a lot of research.


    However, limited by the level of science and technology, even if relevant technologies have appeared very early, and the laser itself has been widely used in many fields such as industrial production, there are even laser weapons that can be used. There are still no laser weapons that can really reach the practical level and can be put into the battlefield.


    To some extent, the laser weapon in front of us is already a very good laser weapon. If we can strengthen the research, the practicality is not too far away.


    However, just when Chen Xin was expecting the laser weapon in front of him, the combat daughter shell as a target was sent to him.


    This is a cut shell, which became easy to obtain after the Dongting Lake theater entered the counter offensive stage. Various research departments obtained a large number of samples as experimental materials.


    The flesh and blood on the back of the shell are basically removed. It can be said that only the chitin part of the outermost layer of the fighting daughter body is left. In terms of defense, it has been weakened a lot.


    But this shell is still strong. If it is put in a game that mainly experiences masochism, it is even a good production material, which can be used to process armor or weapons.


    But even so, there is still a scorched black on the surface of the shell, almost burned through in the middle, and even on the back.


    It can be said that this shell can not resist the irradiation of laser and will be burned through in a very short time. Even when it is still growing on the combat daughter, it has flesh and blood as support and buffer.


    However, Chen Xin is not satisfied with this effect.


    He reached out and buttoned the blackened place on the buckle shell. He found that even the carbonized part still had enough strength. Even if he pulled his fingers several times, he just pulled out a small hole.


    This made him very disappointed, shook his head and asked the researchers aside, "how long did the irradiation last?"


    "5 seconds, which is the most suitable irradiation time we tested before. Although it can reach 12 seconds at most, the machine will overheat in 7 seconds, so we only irradiate for 5 seconds for safety." the researcher on the side hurriedly explained that he also saw that Chen Xin seemed very dissatisfied.


    Sure enough, Chen Xin shook his head and said: "This efficiency is too low. At a distance of 20 meters, these alien creatures can rush in front of you in only one second on the battlefield. In such a short distance and time, you won''t have the opportunity to use this thing to cause fatal injury to it. It''s even difficult to burn through the shell. At most, it just leaves a scorched scratch on the surface of its shell."


    Chen Xin''s evaluation immediately made many researchers look at each other. They didn''t expect that Chen Xin, who came back after a year''s absence, would give such an evaluation in the face of their hard-working research results for a year.


    However, before Chen Xin finished his words, he still shook his head and said: "the efficiency of laser irradiation is too low. Although it does have a good damage effect, if it can last longer or concentrate more lasers on the same place for fire collection, the effect should be good, but it can''t be done on the battlefield.


    The number of alien creatures on the European battlefield is far more than that in the Dongting Lake theater. I don''t know how many times. That''s really the same as the sea. Do you think your laser weapon can dry the sea? "


    "This... No, no weapons can dry the sea." facing Chen Xin''s question, the researchers quickly shook their heads and showed a lost expression on their faces.


    Chen Xin saw the loss of researchers, but he didn''t say anything: "however, what we need to face is the literal enemy of the sea. If the weapons you designed can''t dry the sea, I''m afraid I can only give an impractical evaluation."


    Chen Xin gave two new research directions and encouraged them: "but you don''t have to be too discouraged. As a prototype, this machine is actually good. You can try to study individual laser weapons and heavy laser weapons next.


    If it can be carried by a single soldier and can burn through the shell or ignite it in one second, it can still be put into actual combat.


    As for the heavy laser weapon, that is to enlarge it and turn it into a high-power irradiation cannon. As long as it is swept, it can cause the incapacitation or death of the irradiated alien creatures. It is also a sharp defensive weapon.


    In short, your research is very promising, but this experimental prototype is not practical at present. Keep working hard! "


    With that, Chen Xin left the laboratory, and the expression on his face was not easy.

 Chapter 792

    The reason why the state let Chen Xin return home is indeed, as he feared, because the counter offensive against alien creatures is not progressing smoothly.


    One of the most important reasons is that all human weapons are developed on the premise of fighting on the ground, and all kinds of heavy firepower are powerful underground.


    Although at the beginning, when the military was planning to carry out the counter offensive operation, it asked Chen Xin to specially develop some equipment, which also played a good role in the counter offensive operation, the narrow underground cave still seriously limited the military''s operation.


    Not to mention anything else, the stray bullets produced by bullets hitting the stone walls around the underground cave are a big headache for the military.


    Although relying on exoskeletons and power armor, stray bullets can cause little damage, some bullets broke soldiers'' helmets, causing facial frostbite or non combat attrition caused by inhaling toxic gases in underground tunnels.


    Moreover, the power armor has enough defense to resist stray bullets, but the bulletproof insert plate of the exoskeleton is not wrapped everywhere, and there are still casualties in the end.


    In addition, in the underground cave, the gap between the strength comparison between the enemy and ourselves and the individual combat effectiveness leads to the military''s attack is not smooth, and it can even be said that the offensive is seriously frustrated.


    If it were not for the military''s powerful weapons such as power armor, Titans and spider robots, and just relying on ordinary soldiers, even with exoskeletons as assistance, they would only be passively beaten or even have no power to fight back in the face of alien creatures in underground tunnels.


    Therefore, in the year Chen Xin went to Europe, since the military launched a counter offensive, some people have been singing down the military''s counter offensive plan and think that they "acted too hastily".


    In some ways, this statement does not have much problem. After all, the achievements made by the military can only be described as difficult.


    But some people with ulterior motives are saying that the military should not counter attack and just live in the alien biosphere. It should not waste people and money to attack the underground, let alone use domestic precious resources to support Europe and build the defense line in Eastern Europe.


    It has to be said that these people''s statements still have a certain market among ordinary people. Especially when these people move out of the countless crimes that European countries have committed against Yanguo in modern history, it is easy to provoke people''s opposition to European countries, oppose countries'' continued assistance to Europe, and even feel that Europeans are dead.


    If in the past, when Chen Xin was just an ordinary person, he might have the same idea.


    In history, these European countries have been sorry to us. Now they are in trouble. We have done our utmost to help them without falling into a well. Why should we repay them with resentment?


    Our own life is not easy. Domestic construction needs resources and investment everywhere. Why use valuable human and material resources on those European white eyed wolves, and finally we can''t say a good word?


    It is precisely because of this trend of thought that some people in China are advocating this idea, trying to cut off ties with Europe, stop assistance to them and use resources to restore domestic production and construction.


    There are even many supporters of this view at the senior level, which undoubtedly makes the senior level very vigilant. The popularity of this trend of thought is not good for the country.


    The high level itself is very clear that the aid to Europe is to resist the more turbulent and difficult alien biological offensive in Europe, and the Eastern European defense line itself is also prepared for this.


    But Chen Xin''s work in Europe was so excellent that he forcibly rescued the European battlefield, which had been pessimistic at the senior level, which reversed the situation of the whole Europe and enabled them to resist the offensive on the European battlefield that was far more terrible than at home.


    The Eastern European defense line has gradually become a backup plan that seems useless when it is increasingly improved and even began to be fortified one by one.


    But the high-level still did not relax their vigilance, because alien creatures attacked from the Mediterranean in Europe, and the defense lines laid by humans were all concentrated on the North Bank of the Mediterranean, that is, part of the European continent.


    As for the South Bank of the Mediterranean, the vast African continent


    Senior officials dare not think about it, but they are secretly preparing for defense, and the Eastern European defense line is also extending towards the Middle East.


    After all, neither Yanguo nor Lucia wanted to be blocked by the European defense line. As a result, alien creatures penetrated the African continent, then broke through from the Middle East and stabbed the two countries in the back.


    In fact, it is precisely out of this concern that the military can''t wait to launch a counter offensive.


    At present, most of the military forces have been invested in the Dongting Lake battlefield. Although the huge domestic reserve forces and militia forces have not been on the battlefield, in case of an alien attack from the Middle East, the military does not have the power to launch an all-round war on both fronts at the same time.


    Although some people commented that this concern of the senior management was groundless, the senior management felt it was inevitable.


    However, due to the fact that some people at the top level have begun to support the idea of withdrawing European forces, after several discussions, the top level finally came to the conclusion that the current situation in Europe should be maintained for the time being, and the military concentrated its efforts to complete the suppression of alien creatures in the Dongting Lake area in the shortest possible time, so as to end the large-scale war in China.


    In this way, domestic forces can be freed up, whether to defend against possible offensives in the Middle East, support Europe, or strengthen domestic construction.


    Because of this high-level decision, in the military''s view, Chen Xin, who can bring great changes to the current war situation, has no reason to stay in Europe. He needs to be recalled to help the military gain an advantage in the domestic battlefield, so as to complete the strategic counter offensive and the elimination of alien organisms as soon as possible.


    Chen Xin understood all this thoroughly during the meeting with the high-level. It is obvious that the high-level and the military have high hopes for him. It can even be said that he has placed the hope of winning the counter offensive on him.


    Although Chen Xin also knows that the country must have more than this plan and there must be other plans that can change the war situation, Chen Xin still feels the heavy responsibility on his shoulders and the importance the country attaches to himself.


    This also makes his nerves relaxed by returning home tense again, even tighter than when he was in Europe.


    After all, if something happens in Europe, there is still room for retreat, but now it is at home. If something happens, he doesn''t think he has a way back, or he won''t allow himself the possibility of failure at all.

 Chapter 793

    In order to understand the current situation and problems encountered by the military, Chen Xin came to the Dongting Lake theater.


    This was the first time he came to the Dongting Lake theater after the outbreak of alien invasion, and went deep into the front of the theater.


    Moving from the dome new town to the Dongting Lake theater, you can clearly see the impact on the original city after the outbreak of the war.


    At the beginning of the invasion, it became a war zone, and some buildings were obviously damaged in the original battle. Even now, there are still traces of gunfire in many places.


    Although it was solidified into a part of the defense line of the whole Dongting Lake, it is obvious that the military will not clean up the ruins and repair the city, but directly use these things to build the defense line. Even in order to build the defense line, many parts of the city have been completely leveled to make room for the construction of the defense line.


    It can be seen that these lines of defense have suffered quite fierce attacks and devastation in the previous wars, and many places have left traces of repeated repair. Even if they are repaired repeatedly, many places still look broken.


    As for the ground, it has long been soaked with the blood of alien creatures.


    Chen Xin doesn''t know whether this land will undergo urban reconstruction in the future, but this land can at least be literally watered by blood, that is, he doesn''t know whether the blood of alien creatures can improve soil fertility and whether it can be used for farming in the future?


    The thinking in his mind is a little divergent, but Chen Xin still noticed that the troops stationed on these lines have become much rarer, and his mental state is relatively relaxed.


    It can be seen that they just stay here, and most of the troops originally stationed on the defense line have left here.


    The reason why they do not need to evacuate is that they left these fortifications because of the attack. Naturally, they can not be said to evacuate.


    In fact, the more Chen Xin moves forward, the more troops he sees.


    On the land that has been ploughed countless times by bombs, the bones of alien creatures are blown to pieces, but also mixed in the soil, scattered everywhere.


    As for the surface of Dongting Lake, it looks like a Xiamen delicacy eaten by Chen Xin. A large number of alien corpses are frozen in the ice layer, and they are stacked one after another. They are blown up one layer after another, melted, frozen, frozen and melted


    The military poured a large amount of ammunition into this area, and even beat out 10% of the ammunition prepared for the Third World War. It can be imagined how many times this lake area has been ploughed, so that now the whole lake water of Dongting Lake is mixed with the remains of alien organisms and fragments of bombs.


    The color of the whole lake has also been dyed into an unspeakable color, which is abstract as if some bad urchin knocked over the paint can.


    However, Chen Xin doesn''t care about it, and the troops on the ice won''t care about it. What they care about is to break into the ground, completely eliminate these alien creatures and win the war for the country.


    Through the frozen lake, Chen Xin came to Junshan island again.


    However, the whole island has completely changed compared with the last time Chen Xin saw it. The military has moved the front-line headquarters here, and a large number of military barracks have been set up on the island. It is obvious that it has regarded it as a forward base and plans to launch a counter attack from here.


    Not only that, the whole island seems to have been completely cut off by a bomb during the war. At the beginning, the cave that Chen Xin once went deep into the ground was blown into a structure similar to a big horn. Some troops are driving into the underground caves from here, ready to carry out the task of paying off the underground caves.


    Although the offensive is not smooth, the military is still expanding the war results as much as possible. One cave after another is being cleared, even with little effect.


    Chen Xin''s arrival was undoubtedly greatly welcomed by the forefinger. Several generals in charge of commanding operations warmly welcomed him.


    After a warm courtesy, Chen Xin asked about the current situation.


    "The current situation is not very good. Although we have won phased victories and successfully invaded the nest of underground alien creatures, it is obvious that after we lost the fire support of aircraft and artillery underground, we tend to be inferior in combat effectiveness." an officer introduced with a solemn expression and a bitter smile on his face: "The reproductive ability of alien creatures has not been affected in previous battles. Although we pressed them back to the ground with strong firepower output, and they did not occupy much advantage in the tunnel, our soldiers were suppressed."


    Listening to this, although he had made psychological preparations before coming, Chen Xin couldn''t help asking, "isn''t the attack very smooth?"


    "Not only is it not smooth, it can be said that we have not been smooth since we broke into these tunnels." another officer on the side complained helplessly.


    The officer who opened his mouth to introduce Chen Xin heard the complaint. Similarly, his face was not very good-looking. He showed a helpless expression and explained to Chen Xin: "In these tunnels, although there is no tide like attack, and the soldiers need to face a small number at a time, they are endless. As long as they stop shooting, they will rush up like a blocked toilet, and they will emerge from the places you can see and can''t see!


    Our soldiers are very limited in such an environment. They are afraid to blow up the caves, so they dare not use powerful explosives. It is difficult for them to kill alien creatures effectively by machine guns alone. Moreover, each cave needs to be sawed repeatedly to attack. After attacking, they have to worry about whether those alien creatures will dig another channel from other places


    In such an environment, our soldiers are very passive. If we didn''t have the spiders and robots provided by academician Chen, I''m afraid it would be difficult for us to maintain the current situation. "


    "It really doesn''t sound very good. Do you have any ideas and plans?" Chen Xin looked at the frowning officers and asked them.


    Although Chen Xin is here to solve the problem, it also depends on what the military thinks.


    After all, according to different tactics, the solutions that Chen Xin can provide are also different. It is still necessary to formulate appropriate solutions according to the military''s ideas and strategies.


    In the face of Chen Xin''s inquiry, the officers in front of him looked at each other, quickly took out a plan already formulated, spread out several supporting drawings in front of Chen Xin, introduced it to him, and then asked, "academician Chen, what do you think of this plan? Can these things..."

 Chapter 794

    The plan put forward by the military is crazy.


    Even when he was a network novelist, his brain hole often opened and joked that there was a black hole above his neck, Chen Xin was shocked by the military''s whimsical plan.


    The plan put forward by the military is not so much an attack plan as a construction plan.


    Speaking of tunnel warfare, the Chinese military had not played this tactic in those years, and still had some experience in how to clear the enemy in the tunnel.


    But these experiences have some limitations.


    After all, whether it''s smoke, fire, irrigation and flooding, or the removal of mountains and mountains by drilling bombs, the effect of dealing with small-scale tunnels is good, but it''s useless to deal with large-scale underground tunnels, especially those that have been dug down for hundreds of kilometers.


    Just like these caves under the Dongting Lake, even if the whole Dongting Lake is melted and all the water is poured in, it is impossible to fill the whole cave.


    As for the use of smoke and other methods, they have not tried, but the huge channel and the underground cave network extending in all directions ensure the ventilation of these caves below. Smoke and poison gas are not worth mentioning at all. Instead, they let their own people do somersaults and feel embarrassed.


    Although the plan of using heavy bombs to blow up underground caves is feasible, after some research and analysis, the military still feels that this plan can not completely eradicate alien creatures underground.


    The military has conducted simulation experiments using supercomputers and Chen Xin''s virtual system to detonate a 5 million ton nuclear bomb underground, which can indeed cause a large-scale collapse of the underground caves in the Dongting Lake area.


    In theory, we should achieve the strategic goal of making all caves and tunnels in this area collapse under the chain reaction and eliminating underground alien creatures.


    However, in the simulation experiment, the military also found that unless they can bury the nuclear bomb deep enough, the power of nuclear explosion cannot be transmitted to the deep underground, let alone collapse the deep underground tunnel.


    As for the use of a more powerful nuclear bomb, it is not impossible, but the greater the power, the greater the impact, and the associated may have an impact on the surrounding cities.


    Their aim is to wipe out alien life, not to trigger a big earthquake in the whole Dongting Lake area.


    Therefore, after many studies, the military decided to adopt a steady and steady plan, push down step by step, and build a stronghold as a strategic support after each distance.


    Stockpile supplies and rest troops in the support point, and then launch a new offensive based on the support point, continue to deepen, gradually and steadily, and completely clear up the whole underground space.


    This plan is highly feasible, and the military is indeed implementing it.


    Although the progress has been slow, it has indeed achieved certain results. Some shallow caves have been cleared and attacked in this way.


    There are no other problems with the whole plan except that the investment is a little larger and the effect is a little slower.


    However, with the speculation that alien creatures on the European battlefield may go south to Africa and attack from the Middle East, and with the gradual deepening of the military, all kinds of heavy weapons can not play their power, and the attack becomes more and more slow, the military has to consider changing its plan in order to speed up the attack and shorten the clearing time of Dongting Lake area.


    This undoubtedly needs to modify the whole plan, and greatly improves the difficulty of marching and construction in underground caves.


    It is easy to say that a group of senior military staff took about half a month to complete the adjustment and revision of the whole plan, shortening the originally expected three-year settlement plan to six months.


    However, what follows is that the military must upgrade the existing weapons and equipment and improve their clearance efficiency in underground caves by at least three times, so as to ensure that the clearance task can be completed on time.


    As for the construction difficulty of underground strategic support points, not to mention, it can be said that many of them, even systematic Chen Xin, seem to be difficult.


    However, in the military''s view, Chen Xin, who can create a series of things that only appear in science fiction works, such as weather controllers that can purify the sky and land aircraft carriers used as airports, must have the strength to solve problems.


    After all, their demands are much simpler than purifying the sky and building a flying aircraft carrier.


    Just looking at these requirements put forward by the military, Chen Xin still has an impulse to curse his mother.


    It is not difficult to upgrade the existing weapons and equipment and improve the efficiency of the military''s collection in underground caves. It is nothing more than the development of a new weapon.


    As for the resource input and cost brought about by the assembly of new weapons, it is also not a big problem when countries can obtain resources from Europe.


    What really embarrassed Chen Xin was the military''s proposal to build strategic support points underground.


    First of all, these strategic support points should have sufficient logistics maintenance capacity to allow troops to be stationed, repaired and replenished.


    Although considering that these supply points may be built hundreds of meters underground, Chen Xin still feels that this is a problem that can be solved.


    However, the military also requires these support points to have sufficient defense against the attack of alien creatures, so that they can maintain the existence of support points when attacked by alien creatures, and even repel the attack of alien creatures.


    In particular, the military also requires that these support points must be built quickly and form combat effectiveness quickly, which really makes Chen Xin want to curse.


    Are you kidding? It''s hard enough for construction personnel to build logistics supply points hundreds of meters underground and have enough defense, and then they have to be able to build them quickly!


    This requirement is changed by any other person in the construction department or R & D department. It is estimated that physics (¨s¡õ '') (¨s©¥©ß) will be on the spot, that is, Chen Xin can also consider whether there are any means to achieve this.


    After all, this unreasonable request is comparable to a sharpshooter pupil who fantasizes about the blue cat all day.


    But perhaps only the completely unreasonable black technology of the blue cat can meet this requirement.


    As for Chen Xin himself, after carefully studying the military''s requirements and plan for three days, he came to the conclusion that the investment in the whole plan was too huge and very impractical.


    Even if they can meet the requirements of the military, the investment in this plan has exceeded the upper limit that the country can afford at present.


    After all, the country has to prevent a possible war in the Middle East, and it is impossible to invest too much resources in this elimination plan.

 Chapter 795

    If the military''s plan takes three years to achieve slow and steady progress according to their original expectation, the input and consumption of this material is also amazing, but because there are three years, although the overall consumption is large, it is still within the range that the country can afford.


    However, when the whole plan needs to be accelerated, shortened from three years to half a year, the overall consumption remains unchanged, and even the consumption increases due to accelerated progress, the plan is beyond the scope of the country.


    Although relying on Chen Xin''s efforts in Europe, the European aid fleet can now transport a large amount of resources from Europe to China every day, and many small mines that have been put into operation in China can also produce an amazing total of minerals, it still can not support the military''s huge plan.


    After all, according to the requirements of the military, the army has to build a small supply point almost every few kilometers to stabilize the caves attacked, and build a large strategic support point every more than ten kilometers to stabilize the surrounding areas


    Considering that alien creatures have dug at least thousands of kilometers deep under the Dongting Lake, covered the provinces and cities around the Dongting Lake along the water system, and built a huge three-dimensional cave network, it can be imagined how many supply points should be built according to the military law.


    Therefore, even if Chen Xin can meet the requirements put forward by the military, the plan will eventually be rejected by the top because of too much consumption.


    Therefore, after careful consideration, Chen Xin put forward another idea.


    The reason why the military wants to build so many supply points and strategic support points is mainly because of the dense network of underground tunnels and the huge number of alien creatures in each tunnel.


    In the face of this simple quantitative advantage, we have to adopt the way of almost building a hard stronghold and fighting a stupid war, advance layer by layer, fight steadily step by step, and hold on to the rest to ensure the smooth progress of the campaign.


    But Chen Xin''s idea is the opposite.


    How many tunnels do aliens dig? Ignore him. His tunnel is his tunnel. Let''s dig a new way down!


    The idea of this tactic is quite different from that of the military. The military wants to eliminate all alien creatures, so it will eliminate them layer by layer from top to bottom. However, Chen Xin''s idea is to dig holes to the deepest layer first, eliminate the mother bodies of alien creatures used for breeding, cut off his military line, and then eat each other''s forces one by one.


    The reason why Chen Xin has this idea comes from the real-time strategy games he used to play.


    After all, in the game, as long as there are resources, the force is just a matter of producing more buildings. No matter how many soldiers die on the front line, it is not a matter as long as the economy in the rear is not affected.


    In those real-time strategy games, the only restriction on the size of troops is the population limit set by the game and the total resources of the map.


    Without the limitation of population and resources, the tactics devised by those crazy real-time strategy players can make the computer emit the aroma of roasted graphics cards.


    However, if the economy is cut off, production buildings are damaged and the economy is affected, players will soon fall into the dilemma of not being able to continue the military line, and then lose their strategic advantage and quickly play GG.


    This is also the biggest difference between real war and game war.


    In the real war, the cold weapon era is to consider how to kill the enemy more and reduce the enemy''s forces, while the war in the hot weapon era is more about fighting comprehensive national strength, depending on whose country can''t carry it first.


    After World War I and World War II, the whole country went bankrupt to see who drained their last war potential first.


    As for the loss of troops and economic losses, of course, they have an impact on the war, but they are not so obvious. They are more a state of gradually losing strategic advantage.


    But the game war is different. It is who can destroy the other party''s economy faster, so that the other party can''t obtain more resources and produce more troops.


    The military still adopts the war thinking cultivated by the real war, so it will build the attack plan with the tactics of clearance and suppression, occupation and so on.


    But for non-traditional players like Chen Xin, who operate more than normal, especially when he can realize his ideas, he can jump out of the original rules and come up with tactics that soldiers in the traditional military field can''t think of.


    Although Chen Xin''s tactic of directly attacking the breeding mother of alien creatures with a drill bit is actually a decapitation tactic in modern war and an ancient war wisdom. There is even a special one in the Thirty-six Strategies to describe this tactic, it is indeed a great innovation.


    After all, the military group wanted to break their heads, but they didn''t think of a tactic that they could dig a tunnel by themselves, bypass these caves already dug by alien creatures, and go directly to the nests of alien creatures deep underground.


    In the final analysis, it''s not that they can''t think of such a tactic, but that they don''t have such an offensive tactic of hitting hundreds of kilometers of tunnels in their cognition.


    In fact, if Chen novice didn''t have a system to realize some of his crazy ideas, he couldn''t think of such tactics.


    With tactics, it''s much easier to achieve it.


    It may be difficult for others to realize this idea, but for Chen Xin, the most difficult thing is to generate ideas, not how to realize them.


    If you want to dig a hole down, the easiest way is naturally to use a drill.


    With the current technology mastered by mankind, it is not difficult to drill a hole one or two kilometers deep, but it is obvious that a small hole that can only go down to one person is meaningless.


    According to the needs of combat, at least a hole as big as a subway tunnel must be dug.


    In order to dig such a large hole, the shield machine is obviously a very easy-to-use tool, but under normal circumstances, the shield machine is used horizontally, and there is almost no shield machine to dig down vertically, because generally, the shield machine is not used to dig down.


    Moreover, even if the shield machine is used to dig a hole downward, it is also necessary to consider how to deal with... When digging a cavity, the original cave and encountering the enemy.


    These problems are not only related to all aspects, but also unprecedented attempts and breakthroughs in many aspects.


    Even if Chen novice holds the system and can completely rely on his brain hole to solve problems that others can''t solve, he still has to deal with these problems carefully and cautiously.


    In particular, it is not only a matter of making a hole, but also how the army should attack.


    After all, it''s easy to dig a hole. The troops can''t directly drop from the hole and hang a rope for thousands of meters?

 Chapter 796

    In a huge plant, Chen Xin is following several staff through the same huge production line to visit the equipment being produced in the plant.


    "Academician Chen, this is the most advanced shield machine in China." the staff pointed to a machine that looks like a flat giant pipe and introduced it to Chen Xin: "this shield machine adopts our latest designed cutter head, which can deal with various complex geological conditions, whether it is hard rock or soft rock, and can have a good tunneling effect.


    Moreover, on this shield machine, we have improved the conveyor belt of the earth bin to speed up the soil conveying efficiency. At the same time, we have also improved the structure of other parts, which greatly improves the working efficiency of the machine. Compared with the original model, the tunneling speed and pipeline laying speed of this shield machine should be increased by at least 12%


    Listening to the introduction of the staff, Chen Xin clearly nodded, approached the shield machine, looked carefully and asked, "how fast is the tunneling speed of this machine?"


    After all, the shield machine is used to dig holes. The efficiency of natural excavation is the first, and the standard to measure the efficiency is naturally how many meters this shield machine can advance in an hour.


    "According to different rock strata, this shield machine can dig 1.5-1.75m every 20-30 minutes, and about 3-5M per hour. It is the fastest shield machine in our hands." the staff was very proud when introducing it.


    Don''t think this speed is slow. In fact, the tunneling speed of shield machine has been very fast at this level.


    Under normal circumstances, it is common to dig only more than ten meters a day.


    After all, the role of the shield machine is mainly to dig the tunnel, and the prefabricated tunnel segments are laid into the excavated tunnel in the process of digging the tunnel.


    In this process, many processes such as excavation, pipe jacking and subsequent construction can be pushed more than ten meters a day, which is a very fast speed.


    Therefore, the shield machine can advance an average of 3-5 meters an hour, which is really a very fast speed.


    But Chen Xin is not satisfied with this, even disappointed.


    The reason is very simple. The purpose of his trip is to prepare excavation equipment for his plan to dig holes and directly attack alien biological nests. He expects that the deepest point of alien biological nests is at least 1000 meters underground, or even deeper.


    At such a depth, even if it is a vertical excavation, more than 1000 meters will have to be excavated for three or four months according to the propulsion speed of more than 10 meters a day, not to mention the possible battles encountered in the construction of supporting facilities and excavation.


    Considering that this is an attack, it needs to transport troops and all kinds of heavy equipment downward, as well as a large number of ammunition supplies and other materials that will be used in combat, it is undoubtedly more appropriate to dig obliquely downward than to drill vertically.


    However, if it is inclined, according to Pythagorean theorem, this inclined tunnel will undoubtedly be much longer than the vertical shaft, and the construction period will also be extended.


    Dig slowly. Of course, that doesn''t mean No.


    Although the time of the military''s plan is half a year, the preparations before the attack and the time delayed by the difficulties that may be encountered during the attack are combined by many factors. In fact, the time set by the military for its own plan is reserved for nine months, and will be postponed according to the actual situation.


    In fact, although the high-level demands to shorten the counter offensive time against alien creatures, and the military has accelerated its own plan, they are ready to fight for at least a year.


    Therefore, if Chen Xin''s attack plan can be completed within one year, it is still within the range acceptable to the high-level and the military.


    But for Chen Xin himself, a year is still a little longer, and he must set aside spare time for the plan, and he can''t completely expect the plan to go smoothly.


    Therefore, the tunneling speed has become a key factor.


    "Can the tunneling speed be accelerated?" Chen Xin asked the staff. At the same time, he was also looking at the shield machine with the system upgrade interface to see whether the tunneling speed can be improved by system upgrade.


    The staff scratched their head and said with some distress: "we also want to speed up the tunneling speed, but the tunneling speed of the shield machine has a great relationship with the material and structure of the cutterhead. According to our current technology, the cutterhead used now is the cutterhead with the highest efficiency we can make.


    If you want to speed up the excavation, you can only transform the cutterhead, either change the structure or improve the material, but neither of these can be completed in a short time. "


    With that, the staff explained in detail to Chen Xin the advantages of the cutterhead now used by the shield machine, as well as the details of its material and structure.


    Although the staff did not know why Chen Xin paid attention to the shield machine, there must be a need in this regard, so he answered Chen Xin''s questions as much as possible.


    Listening to the explanation of the staff, Chen Xin frowned slightly. Although he can improve the material and structure of the cutterhead by means of system upgrading to make it more efficient, the efficiency that can be improved is not much.


    According to the staff, even if the cutter head is improved, no matter how the efficiency is improved, it can only increase the propulsion speed by 50% at most, which is the limit.


    This is already a very satisfactory result. As long as this speed can be guaranteed, the whole tunnel excavation can be completed within the originally planned time, and even there can be spare time to make room.


    But this is not enough for Chen Xin. After all, he needs to consider a very important factor, that is, the combat time other than excavation.


    Whether it is the alien nest itself in the deep strata or the huge number of alien creatures scattered in the underground caves, the military''s attack and suppression of them will take time.


    If it takes more than half a year just to dig a tunnel, there will undoubtedly be little time left for the military to fight. This is obviously not in line with Chen Xin''s idea of quickly solving the problem of the Dongting Lake theater in a short time to deal with the possible enemy situation in the Middle East.


    Of course, if the problem of the Dongting Lake theater cannot be solved in a short time, Chen Xin is not without other solutions.


    For example, the general''s current offensive is suspended and turned into a defensive posture, blocking the possibility of alien creatures attacking the surface, and then while driving, he turns his troops and manpower into the construction of a defense line to prevent the Middle East.


    When the defense line is repaired, the progress of excavation is almost the same, and then launch the offensive again to solve the problem of alien creatures in Dongting Lake area.


    However, this scheme is only an alternative plan. Before that, Chen Xin still hopes to shorten the time required for tunneling as much as possible.


    So he asked the staff a whimsical question: "can you replace the cutterhead with a drill bit?"


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 797

    Can the cutter head of shield machine be replaced with drill bit?


    If someone else asks this question, the staff may not even bother to answer, and just give the person a blank eye.


    But Chen Xin asked this question. The staff must seriously consider how to answer and explain, so that Chen Xin can understand that this is impossible and save face for him at the same time.


    However, even so, in the view of the staff, this idea is still impossible.


    Although the Cutterhead of the shield machine itself is equivalent to a huge drill bit, the staff also understand that Chen Xin means whether the cutterhead like a large flat plate in front of the shield machine can be replaced with that kind of pointed drill bit.


    After all, in the eyes of many people, the efficiency of drilling is so high that many cartoons or some science fiction works have machines that can quickly dig in the soil with a large drill in front.


    It takes a lot of time to explain the specific principle, but there is a very simple and easy to understand explanation, that is, if the spiral bit is really easy to use, why don''t we use that bit to dig holes?


    Naturally, the answer is also very simple. Naturally, it is not easy to use. We don''t need such a drill bit.


    In fact, as long as people have a little understanding of the drill bit, they will find that the front end of the structure of most drill bits basically tends to be flat, and there are few very sharp drill bits.


    This is mainly because the bit is usually used to drill hard objects. If the bit tip is too sharp, it will be easily worn out, affecting the service life and effect of the bit.


    Therefore, most of the bits are designed with a flat head as possible and made of hard metal to enhance their durability.


    The cutter head of the shield machine is actually a rotating mechanism with grooves. A large number of blades are installed on it to cut rocks and soil layers. Although it can be regarded as a huge bit, this does not mean that the cutter head of the shield machine is really a bit.


    When the Cutterhead of shield machine works underground, it will encounter various strata with different hardness, resulting in the stress of cutterhead is very complex. It is not the kind of screw bit working in uniform medium, so the stress can be ignored.


    Therefore, the machine whose front end is a drill in cartoons and science fiction is only imagination, but can not be applied to practice.


    After listening to the staff''s explanation, Chen Xin was naturally embarrassed and felt that his ideas were a little whimsical.


    However, his idea is not impossible. After all, with the system in hand, Chen Xin can do many things that others can''t do.


    Of course, even if there is a system as a backer, Chen Xin will not win blindly. At present, since professionals say that changing drill bits is not feasible, he will not say that he has to try.


    The most appropriate way is to do an experiment first. Just like the original Dome City and ecosystem, do several simulation experiments, and naturally you can know whether it is feasible.


    To understand this, Chen Xin did not continue to embarrass the staff, but told him that he might need a super large shield machine to perform the task, and then left the factory.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Returning to his office, Chen Xin first input the shield machine drawings brought back from the factory into his watch, and then projected them with nano molecules.


    Looking at the shield machine model projected in front of him, Chen Xin studied the model and thought about how to upgrade it.


    The principle of shield machine is to cut the front end continuously, and then install the segments one by one into the excavated pipeline, so as to realize the rapid construction of tunnel.


    Therefore, what affects the working efficiency of shield machine is the cutting efficiency of front-end cutter head.


    This is also the reason why Chen Xin wanted to replace this cutterhead with a drill bit. In his opinion, the cutting efficiency of the drill bit is undoubtedly higher than this cutterhead.


    Although the professionals in the factory said it was unlikely, Chen Xin did not completely give up the idea.


    With the idea of trying, Chen Xin first upgraded the drawings of the shield machine to the form that the front end is a large drill bit.


    Then the virtual simulation system is started to simulate and test the actual use of this structure.


    However, the result disappointed Chen Xin, because the drill bit was solid. In the process of underground drilling, a lot of heat was generated due to continuous cutting and friction, which could not dissipate heat. Finally, it was damaged due to local high temperature and wear.


    Obviously, this plan is really whimsical and not very practical.


    Therefore, Chen Xin quickly adjusted his thinking.


    Since the drill bit is not practical, what about adjusting the structure of the cutterhead?


    With this in mind, Chen Xin upgraded and adjusted the drawings again, upgraded the original cutter head of the shield machine to a slightly convex shape in the center, and optimized the structure.


    This time, the effect was satisfactory. Although the tunneling efficiency was not improved much, the adjusted shield machine completed the excavation smoothly.


    This result undoubtedly encouraged Chen Xin and made him clear his ideas.


    The idea of not cutting the actual bit is abandoned, and the cutterhead structure and working mode of the shield machine are studied in order to improve its working efficiency.


    The Cutterhead of shield machine is mainly used to loosen, break and excavate soil or rock underground. Due to its huge size, its working speed is not fast, even slow.


    After all, if it''s fast, the heat generated by friction is amazing.


    Chen Xin tried to double the rotation speed of the cutter head of the shield machine, but the result is not the improvement of work efficiency, but the melting and wear of the cutter head on the same cutter head due to high temperature, and finally the whole cutter head is damaged.


    This undoubtedly creates great restrictions on Chen Xin, which makes him need to think about a more appropriate scheme.


    Although the system upgrade can do things that cannot be done under normal circumstances, the basic physical laws that should be observed should still be observed. If Chen Xin can''t improve a reasonable and feasible scheme, even the system upgrade will just create an industrial waste with no practical value.


    Therefore, Chen Xin must seriously conceive a reasonable scheme and make a breakthrough while being reasonable, which is also a very arduous task for him.


    In particular, he also needs to come up with a feasible plan as soon as possible, so that the military can start implementing it as soon as possible and save time.


    "Hey, it looks like we''re going to work overtime again!" Chen Xin smiled bitterly, but he didn''t feel too depressed. Instead, he cheered up and put himself into work.

 Chapter 798

    On the frozen lake surface in Dongting Lake area, a group of engineers are drilling holes into the ice and burying the prepared explosives after drilling to a certain depth.


    Instead of blasting the ice, they intend to use the seismic waves generated by the explosion to carry out geological exploration underground and determine the location and trend of underground caves.


    This is to prepare for the tunneling attack plan formulated by Chen Xin.


    Although when designing this scheme, Chen Xin made preparations for how to prevent the damage of shield machines and tunnels by those alien creatures in the underground caves, if possible, both the military and Chen Xin hope to find a excavation route that can avoid those existing underground caves.


    On the one hand, it can save a lot of trouble. After all, if you can directly dig down to the nest of alien creatures without interference and then attack directly, it is really very worry-saving and labor-saving.


    For the military, this is undoubtedly the most ideal state.


    On the other hand, it is to minimize the construction difficulty in the excavation process.


    The shield machine prepared by Chen Xin for this excavation task is at least more than 70 meters long and more than 10 meters in diameter. If the machine falls down because of digging a cavity, it will undoubtedly cause great damage to the machine.


    Therefore, planning a reasonable excavation route has become an important prerequisite for the implementation of the whole plan.


    While these engineers were burying explosives, another group of engineers were cooperating with the engineers in the tense construction in the original urban area.


    Their task is to dig a large foundation pit here for placing the shield machine.


    Although this excavation offensive does not need to dig down first and then hoist the shield machine down like the subway, it still needs to excavate a pit in advance and clear the starting position to facilitate excavation.


    After all, the whole shield machine is tens of meters long and weighs amazing. The excavation is inclined downward with a certain angle. It is impossible to raise the tail of the whole shield machine to the sky.


    On the construction site, Chen Xin is inspecting the progress of construction.


    "The construction period is very tight. Are you confident to complete the task?" Chen Xin asked the construction director aside.


    Because both the high-level and the military hope to solve the problems in the Dongting Lake area as soon as possible, they are very worried about the construction period card.


    "Please rest assured that we have divided the workers into three shifts, with 24-hour rest for people and machines, so as to ensure the completion of the construction of the foundation tunnel within the specified time!" the person in charge looked very confident with his words.


    In fact, the person in charge is really confident in completing the construction. On the one hand, he has sufficient manpower. The military even provided some engineers to assist the construction.


    On the other hand, the construction itself is not a particularly complex and large-scale construction. It is just digging a deep pit to complete the foundation tunnel erected by the shield machine.


    Although the construction requirements are very strict and the construction period is tight, it is still within the scope that can be completed. It just needs to be constructed very efficiently without any time to make mistakes and waste.


    However, this is not too harsh. As long as there are no mistakes in the construction, we can basically ensure the smooth completion of this task.


    Chen Xin nodded with satisfaction. Since the person in charge was so confident, he naturally wouldn''t say much.


    At the same time of construction, a huge shield machine is being assembled on the side of the construction site.


    This is the shield machine required for this mission obtained by Chen Xin after upgrading the system with a finished shield machine ordered from the factory.


    He spent almost a week trying again and again before, and finally got the machine that can dig 50 meters a day.


    Chen Xin used the concepts and ideas of some sci-fi films he had seen a long time ago for reference, and further improved the cutter head of the original shield machine.


    In addition to improving the material and structural efficiency of the cutter head, Chen Xin also installed a directional acoustic transmitter on the cutter head.


    This is somewhat similar to the sonic gun. The transmitter will emit ultra-high frequency sound waves in the direction of excavation, so as to loosen the soil and break the rock and improve the excavation efficiency.


    In fact, 50 meters a day is not the limit of this machine. According to Chen Xin''s design and simulation results, this machine can dig more than 100 meters a day at most if it is driven with maximum power, but then the subsequent tunnel construction can''t keep up.


    Therefore, after careful calculation and evaluation, Chen Xin controlled the excavation speed at the most appropriate speed of 50 meters a day.


    This can not only ensure the construction of each section of excavation, but also ensure the excavation speed, and will not delay too much time.


    According to Chen Xin''s prediction, the whole excavation project needs to dig down about 4000 to 5000 meters. Because it is inclined excavation, the distance is several times the vertical depth.


    The time he prepared for the whole plan was about nine months, and the construction period was about three to four months. The remaining time reserved was for the military.


    The military has no objection to this. According to their estimation, if the mother of alien creatures used to produce combat offspring can be successfully removed in the first wave of attack and their recruitment can be cut off, the military is confident to end the battle within three months.


    Chen Xin is not optimistic about this. He is always worried that there are higher units for alien creatures, and it is uncertain what is hidden in the underground alien creatures more than 1000 meters deep.


    The military''s estimate of the end of operations in three months is only the result of the current situation.


    According to Chen Xin''s calculation, even if the offensive goes well, it may take the military four to five months to end the whole campaign.


    If anything happens, the whole operation will last longer.


    In this regard, Chen Xin has also expressed his concerns to the military, and the military has made plans and adjustments for this, but they do not intend to modify the original timetable and still intend to complete all the clearance and suppression operations within three months.


    This inevitably makes Chen Xin feel a little worried about whether the military is too confident.


    However, the operational plan formulated by the military is very rigorous, and all parties have left enough margin for emergencies and prepared standby plans. It really doesn''t look like excess self-confidence.


    Facing this situation, Chen Xin had to put down his worries and focus all his energy on the implementation of the plan.


    After all, there are many things to consider and prepare for in order to dig more than 1000 meters underground in three months and launch a large-scale operation. As the proponent of the plan, Chen Xin still has a lot to do.

 Chapter 799

    While Chen Xin was preparing for the excavation plan, the military also slowed down its offensive. They abandoned some caves and tunnels that had been beaten down, and instead stuck to the areas that had been stabilized. In addition, they planned to blow up many channels and seal all the roads broken by alien creatures, leaving only some holes for their own use.


    After such an adjustment, the military only needs a small number of troops to hold a few main channels left, which can block the upward attack path of alien creatures.


    And because of this change from attack to defense, most of the troops originally prepared to attack the underground have been idle for a while.


    The military did not really let these troops idle. In addition to allowing them to continue to monitor the whole Dongting Lake area to prevent alien creatures from digging new channels to rush out of the ground again, it made these troops prepare for the next clearance and suppression operations.


    Before the military offensive has not been very smooth, on the one hand, it is the relationship between weapons, on the other hand, it is also because it does not adapt to the underground tunnel environment.


    For this reason, the military plans to conduct a training for the existing troops during the three months of excavation work to adjust the status and tactics of the troops, so as to play a stronger combat effectiveness in the subsequent clearance and suppression operations, and better adapt to the operations in underground caves and tunnels.


    To this end, the military specially reserved a small section of the tunnel close to the surface, which was not completely sealed, and opened it up with the ground. The idle troops were rotated into the tunnel and engaged with the combat sons in the tunnel, so as to study the tactics of fighting in the tunnel and cave.


    Because it is a specially reserved tunnel, the number of alien creatures in the tunnel is not as exaggerated as other tunnels. The military also has more room for trial and error and research tactics.


    By constantly putting the troops into the tunnels to fight, allowing them to explore more applicable tactics and directly carry out actual combat test, the military quickly explored a set of applicable tactics and soon extended them to all troops.


    However, the military is not satisfied with this. On the one hand, they continue to let the troops explore tactics, while looking for Chen Xin, hoping that he can provide some more practical equipment for underground operations.


    Chen Xin had expected the requirements put forward by the military. After all, the military put forward relevant requirements when discussing the attack plan several times before.


    Just for the requirements put forward by the military, Chen Xin has no good ideas.


    Limited by the environment in the underground tunnel, all kinds of heavy vehicles can''t get down at all. At most, some small vehicles such as SM assault vehicles can pass through.


    Moreover, due to the narrow and complex terrain in the underground tunnel, heavy firepower such as various artillery can not be used at all. After all, a single shot can only hit more than 100 meters, and it will explode into the stone wall. If it is powerful, it will even lead to the collapse of the tunnel. The military will not use heavy weapons under such circumstances.


    Even Titan''s hand guns were abandoned and only rotary machine guns were used.


    However, even for rotary heavy machine guns, there is still the problem that bullets will jump when they hit the rock wall.


    This has had a great impact on the promotion and operation of the army, and it is also difficult for the military to achieve more brilliant results in previous operations.


    This also makes Chen Xin have great restrictions on the conception of new weapons.


    According to the requirements put forward by the military, Chen Xin can only think of tossing on the small platform such as the military''s existing Bobcat assault vehicle, or designing new weapons for Titan.


    As a small multifunctional vehicle platform mainly equipped by the army, SM assault vehicle has many advantages, such as light weight, small volume, multiple functions and strong adaptability. The army developed a series of modifications around SM assault vehicle before the disaster, forming a vehicle family.


    Among these modifications, there are many 40mm assault guns and 120mm forced howitzers, which can be called crazy modifications.


    You know, the bobcat assault car is very small. The length of the 6 * 6 body is only about three meters, and the self weight is not even a ton.


    However, even if the SM assault vehicle can resist 120mm caliber artillery, it can not shoot effectively in the underground tunnel environment. The military is not crazy enough to use this caliber artillery for tunnel warfare, so most of the time, it is still equipped with heavy machine guns or small caliber artillery.


    Even so, there are still many problems in the use process.


    Therefore, the military urgently hopes to solve the problem that it is unable to use high-power weapons in underground tunnels and put all kinds of heavy weapons into combat in order to win.


    However, powerful weapons are big explosions. In order to pursue the killing effect, the 85mm grenade can produce about 900 effective fragments, which can kill the enemy within 280 square meters. In the narrow tunnel, it is often one shot and hurt both the enemy and ourselves.


    This leads to that even if Chen Xin has a system, he really doesn''t think of any good ideas.


    After all, the powerful weapons the military wants are all this virtue. The greater the power, the greater the killing area. It''s really difficult to use in the tunnel.


    Before, the military mainly relied on heavy machine armor and Titans to open the way and achieved certain results.


    But it also caused terrible losses to Titans and heavy mecha. Logistics statistics concluded that the number of Titans and heavy mecha lost during the period of military rework was more than the total loss in the previous defense stage!


    And more importantly, the driver''s loss.


    The heavy machine armor in the tunnel is OK. At least it is not so big, and there is more or less room to move and dodge. However, for the Titan, one can almost block a tunnel. There is room to dodge only in some spacious caves, which undoubtedly makes the Titan bear a lot of attacks and causes a sharp rise in driver casualties.


    Facing this situation, Chen Xin himself urgently hopes to come up with the heavy firepower that can be used in the environment of underground tunnels, so that the military can play a stronger combat effectiveness in the next battle.


    After all, even if the operation is carried out by tunneling, the military still has to go deep into the underground tunnels to fight. If there is no input of new weapons and only tactical changes, I''m afraid it is difficult to reduce casualties and equipment loss.


    But this is not an easy thing to do. Even if Chen Xin can save a lot of research and development time, he has no clue and inspiration at this time and can''t think of how to solve this problem.


    Gripping his head in distress, he crumpled the draft paper covered with various ideas and threw it into the corner. Chen Xin was trapped: "the road of live ammunition weapons is impassable. Do you want to consider non live ammunition weapons?"

 Chapter 800

    "This plan doesn''t work! Damn it!" frowning, he crumpled a piece of draft paper in front of him and threw it out. Chen Xin felt very upset.


    There are a lot of the same paper balls on the floor of the office. Obviously, Chen Xin''s work is not going well.


    "What''s the matter? What''s the problem with throwing so much waste paper?" he raised his finger and knocked twice on the opened door. Qin LAN looked at the waste paper ball in Chen Xin''s office and couldn''t help asking him curiously.


    While asking, Qin Lan also found a broom at the door of Chen Xin''s office and cleaned the waste paper ball on the ground.


    While cleaning the waste paper ball on the ground, Qin LAN couldn''t help complaining to Chen Xin: "I didn''t say, ah Xin, your habit of throwing waste paper at random really needs to be changed. At least it''s also the leader of a department. You let your people see what it looks like like like like."


    "It''s annoying to get so much." Chen Xin looked at Qin LAN and stopped his work. The whole man leaned back on the chair and rubbed the bridge of his nose tired.


    Qin Lan''s hands and feet were very sharp. She soon cleaned up all the waste paper in Chen Xin''s office and stuffed it into the dustbin, although it made the dustbin full and about to pile up into a hill.


    After cleaning up the garbage, she came to Chen Xin''s back, helped him rub his temples, and asked with concern, "Why are you so annoying? Is your work not going well? Or do you have any problems?"


    With his eyes closed and enjoying Qin Lan''s massage, Chen Xin took a breath and explained: "the military needs heavy weapons that can be used in underground caves and tunnels. The existing weapons are not suitable. I can''t find ideas for a while and a half. It''s inevitable that I get annoyed!


    You should know that the tunneling plan has now begun. It is less than four months before the military starts to attack. I must come up with a feasible plan before the tunneling is completed, so that the military can have useful weapons to carry out underground clearance operations! "


    "Don''t push yourself too hard." listening to Chen Xin''s explanation, Qin LAN can''t say anything comforting to him.


    Of course, she knows how important Chen Xin is responsible for. If he can come up with a feasible plan one day earlier, it means that many casualties can be reduced.


    In this case, Chen Xin naturally can come up with the results as soon as possible. Qin Lan also hopes that he can come up with a feasible plan one day earlier.


    But as Chen Xin''s girlfriend, Qin LAN looked at his tired and troubled appearance, and more was distressed. She hoped that Chen Xin would not let herself be so tired.


    Qin LAN can only persuade Chen Xin to pay attention to his body and don''t force himself too much.


    Chen Xin felt more comfortable when Qin LAN gently rubbed his temples. He reached out and held Qin Lan''s left hand rubbing his forehead, put her palm close to his cheek, and felt the softness of Qin Lan''s palm. He couldn''t help but relax.


    During this time, in order to solve the problem of the Dongting Lake theater, Chen Xin stretched himself very tight. He has been working overtime in the office for many days and has never been home.


    Since he came back from Europe, he has stayed at home for a few days, and then he has devoted all his energy to his work.


    First, the military''s attack plan was revised, then the shield machine was adjusted and upgraded, and now we have to consider new weapons


    It can be said that Chen Xin has not been idle since he came back from Europe.


    In the face of Chen Xin''s busy and heavy work, how can Qin LAN not love her lover?


    But both she and Chen Xin understand that the more this time, the less time to rest.


    After being warm with Qin LAN for a while, Chen Xin pulled Qin LAN into his arms, let her sit on her lap and asked her, "why do you have time to come and see me today?"


    "Because you have revised the counter offensive plan, most of the troops have been idle recently. Every day, in addition to training, they are studying tactics, so they are relatively idle." Qin LAN leaned against Chen Xinhuai and specially adjusted his sitting posture to avoid the metal prosthesis from hitting Chen Xin: "Zhu Luan had a small problem because of high-intensity combat some time ago. Taking advantage of the fact that there was no combat task during this period, he just sent it for maintenance. I also had a two-day holiday.


    Originally I went to see my uncle and aunt, but they said you hadn''t been home for a week. Please let me see your situation, so I came. "


    "It''s hard for you. During my absence, if you and Qingyan hadn''t accompanied my parents, I really can''t rest assured that they are old." Chen Xin couldn''t help feeling when Qin LAN mentioned his parents.


    Although he said that he knew that the state would take good care of his parents'' lives, and even a special person was responsible for their daily life, Chen Xin was very worried that he was not around to take care of them.


    And for the elderly, they also need someone to accompany them. Especially now, they can''t contact relatives and friends at home, and they don''t have any entertainment projects. They can only take care of each other at home every day. If Qin LAN and Mo Qingyan didn''t visit them often, Chen Xinzhen is worried about whether their parents will have any problems because of loneliness.


    "What are you talking about? This is what we should do." Qin LAN blushed when she heard Chen Xin say this: "and it''s mainly Qingyan who is accompanying them. I''ve always had combat missions here before. I seldom have time to visit my uncles and aunts. Unlike Qingyan, who can often talk with them."


    "That should also thank you. When I was away, they were thanks to the care of you two." Chen Xinchong and Qin LAN smiled and suddenly joked: "when did you and Qingyan change their words? They are closer than me to my parents and call my uncle and aunt. Don''t you feel strange?"


    Hearing what Chen Xin said, Qin LAN bashfully hammered him on the chest and said angrily, "what are you talking about? You''re not married, what are you talking about!"


    After being hammered by Qin LAN, Chen xinlai said it didn''t hurt or itch, but this flirting made him suddenly feel much better, so he simply hugged Qin LAN and kissed her on the face.


    This made Qin LAN more and more shy. She glanced nervously at the door of the office, which broke away from Chen Xin''s arms and stood up: "don''t do this in the office! Being seen has a bad impact on you!"


    Qin Lan''s shy appearance immediately made Chen Xin laugh. If it was before, I''m afraid he can''t imagine Qin LAN showing such a shy appearance in front of him?


    However, just when he was ready to say something to Qin LAN, the door of the office was suddenly knocked. A researcher came in and said to Chen Xin with a somewhat excited look: "academician, the laser weapon project has made a breakthrough!"

 Chapter 801

    In the laboratory, Chen Xinzheng and Qin LAN watched this laser weapon test together.


    The researchers who came to Chen Xin just now told him that the laser weapon had made a breakthrough, so he came to the laboratory with Qin LAN. In order to show him the research results, the research team prepared this experiment.


    In front of Chen Xin is the laser weapon he has seen before, but obviously some improvements have been made.


    Twenty meters in front of it is a new combat daughter shell as the target.


    "Let''s start. Let me see what breakthroughs you have made." after that, Chen Xin motioned the researchers aside to start the test.


    "The fourth experimental laser irradiation weapon, the third damage test, the target combat daughter''s back armor, the purpose of the experiment is to test the damage effect of the laser irradiation weapon on alien organisms." he is still the researcher in charge of reporting when Chen Xin came to watch the test last time. After finishing the experimental project, this time he did not ask Chen Xin for instructions, so he shouted, "the test begins!"


    With that, another researcher pressed the button on the console.


    It is slightly different from the scene seen by Chen Xin last time. Although a laser irradiates the target, this time it is not ablation, but almost within a second or two after the laser irradiates it, there is an explosion on the shell as the target, but the explosion is very small. It just blows a hole in the shell and splits it in two.


    Chen Xin couldn''t help but pick his eyebrows and looked at the researchers aside in a little surprise: "how did you do it?"


    "We changed our thinking." facing Chen Xin''s surprise, the leader of the project team explained to Chen Xin: "before, we always used continuous laser to continuously irradiate the target and use thermal damage to achieve the purpose of material melting and damaging the target. This is also our main research direction, that is, using laser weapons to fight low and slow small targets.


    However, what academician Chen said to us last time, especially the metaphor of drying the sea, made us realize that our research direction needs to be adjusted. What we need to deal with is not low, slow and small aircraft, but alien creatures with large size, fast moving speed and strong defense.


    Therefore, we replaced the original continuous laser with pulsed laser. At the beginning, we intended to irradiate with high-power density laser to achieve the effect of laser cutting. However, in the test, we found that the pulsed laser would produce considerable kinetic energy impact at a certain frequency, so we adjusted the machine and used the kinetic energy impact generated by high-frequency laser to damage the target.


    This adjustment is not easy, but fortunately, we also have some research in this field before. After several experimental adjustments, we have the test machine you see now, academician Chen. At present, the effect is good. "


    After listening to the explanation of the researchers, Chen Xin nodded clearly.


    No wonder the project team came up with a new experimental model so soon. It turned out that there had been research in this field for a long time. Now, relying on the door-to-door play, we have a laser weapon that is already considerable in Chen Xin''s view.


    Although in Chen Xin''s opinion, this laser weapon is still a long way from being practical in the battlefield, on the whole, it is a promising laser weapon.


    It only needs some more time to study and improve, and it can be installed in the army.


    "Your achievements this time are very good, and this laser weapon is also very promising, but my suggestion to you is not to give up the previous research." Chen Xin affirmed the achievements of the project team, but also felt that it was not necessary to give up their previous research.


    Although I felt that the power of the laser weapon was not enough and the damage effect was not good enough in the last test, it was also a scientific research route worthy of investment in development and research.


    "Academician, please rest assured that we have not given up the research of continuous laser, but at present, our research team is short of manpower and can not carry out the research of two topics at the same time, so we have focused our manpower on the research of pulsed laser." the leader of the research team explained to Chen Xin that the previous research is also the result of their hard work, and the research has not failed, Naturally, I will not give up casually.


    Even if it does not have practical value, it will be reserved for technology accumulation, not to mention that it is also a promising research project.


    Hearing what the team leader said, Chen Xin nodded with satisfaction.


    Although he had been upset about the development of new weapons before, now after Qin Lan''s comfort and watching a successful experiment, he has relieved his boredom.


    This makes Chen Xin feel relaxed and ready to go back and start his work again, but Qin LAN grabbed him.


    "Ah LAN, what''s the matter?" Chen Xin was a little strange. He didn''t understand why Qin LAN held him.


    "Aren''t you studying new weapons? Isn''t this laser weapon!" Qin LAN whispered to Chen Xin, a little excited: "I''ve fought in the underground cave environment before. This laser weapon is better than live ammunition weapons!"


    Hearing Qin Lan''s words, Chen Xin was stunned and immediately reacted.


    Yes, laser weapons are really suitable for use in underground space. It is a non physical weapon. Naturally, there is no problem that those live ammunition weapons will jump.


    As for the problem of insufficient or excessive power, it is not a problem for Chen Xin.


    After all, laser weapons are energy weapons, and the output power can be controlled by adjustment. There is no case that the explosion power of fixed ammunition such as missiles or shells is fixed and uncontrollable.


    Moreover, the volume of this laser weapon is not large. It can be installed on the SM assault vehicle that Chen Xin was very optimistic about before, and made into a mobile laser launch platform to provide fire support for the troops in the underground caves.


    Thinking of this, Chen Xin was also excited. He suddenly hugged Qin LAN and kissed her on the face. Only then did he excitedly ask the researchers on the side: "how long can you rebuild such a laser weapon?"


    "Well, this..." the researcher was overwhelmed by Chen Xin''s sudden excitement, but he quickly replied: "if there are enough raw materials, it will take about three days to install and debug. The technology is mature. As long as the parts are assembled, now with 3D printing equipment, it is very convenient to produce these parts."


    Hearing what the researchers said, Chen Xin nodded with great satisfaction and said to him, "please make another laser weapon like this... No, two. The previous one also makes one. Will you have five days? Tell me what you need and I''ll solve it."


    "Enough," the researcher replied positively.

 Chapter 802

    In Chen Xin''s exclusive laboratory, a six wheeled car less than three meters long was parked in front of him.


    The car body is short and compact, leaving only two seats for the driver''s seat and the co driver''s seat. The car is equipped with a round machine that looks like an astronomical telescope. It is almost one-third the length of the car, and the supporting base occupies the second half of the car.


    This is Chen Xin''s new weapon inspired by Qin LAN.


    Laser weapon launching platform transformed from the chassis of Bobcat assault vehicle.


    Chen Xin has made two versions, using pulse laser and continuous laser respectively. After small-scale trial production, he will send them to the military for testing to determine the specific mass production model.


    However, Chen Xin is more optimistic about the version of pulsed laser, mainly because the damage effect of this laser is better than that of continuous laser.


    Of course, after Chen Xin''s upgrade, the damage effects of these two lasers have reached the standard of practical weapons, but the operation mode is different.


    The six wheel assault vehicle equipped with two kinds of laser weapons is light and compact, and the six wheel chassis also has quite good traffic capacity. It can have good mobility even in underground tunnels.


    After Chen Xin''s adjustment and upgrading, the laser weapons carried by it only need to irradiate for about 0.5 seconds to effectively kill the combat daughter.


    Although it sounds like it only shortens the time from a few seconds to a few tenths of a second, it doesn''t seem much, in practice, it undoubtedly greatly improves the killing efficiency of laser weapons.


    For a simple example, if it takes 2-3 seconds to irradiate a combat daughter to cause effective damage and break through its chitin exoskeleton shell, how can we ensure that the laser can irradiate the same position for at least 5 seconds in the battle of the underground tunnel?


    You should know that under the combat ring of the underground tunnel, alien creatures still have a high mobility. In addition to moving on the ground, they can also climb on both sides and top of the cave. In this environment, it is not easy to point the laser at the moving target and maintain the irradiation time of a few seconds.


    In this case, the best way to shorten the laser irradiation time is to achieve the kind of irradiation in science fiction that can be lit, even pierced and cut.


    However, although Chen Xin, a laser weapon with high power rate and high damage, can be built through system upgrading, it is not suitable for production.


    At least in a short time, there is no way to achieve mass production to meet the needs of the military to eliminate alien creatures in underground tunnels in counter offensive operations.


    The irradiation time of 0.5 seconds can be effectively damaged. Such laser weapons can not only meet the use needs of the military, but also facilitate production.


    Chen Xin has already asked the factory. It only needs a little adjustment of the production line. The production of other parts is ready-made. In a month, 100 small assault vehicles equipped with laser weapons can be equipped to the army to meet the needs of the army.


    However, Chen Xin still tried to make a laser weapon with power that can instantly cut the body of the combat daughter within the effective irradiation range in case of need.


    Of course, the laser gun with the power to instantly cut the body of the combat daughter is not suitable for loading on the assault vehicle, but more suitable as a weapon of Titan.


    The greater the power, the greater the energy required. For small assault vehicles, even if they are equipped with nuclear batteries, the energy power they can output is limited. Meeting the consumption of an ordinary laser weapon is the limit.


    Titan, on the other hand, can output much more energy and power than small assault vehicles.


    Out of this consideration, Chen Xin is also ready to replace Titan with laser weapons.


    After all, if Titan could be equipped with more powerful laser weapons and sweep away those alien creatures directly in the tunnel, the combat efficiency would undoubtedly be greatly improved.


    But Chen Xin still has some concerns about the actual use effect of laser weapons. He plans to wait until the military puts two assault vehicles equipped with laser weapons into actual combat to test the effect, and then consider whether to replace Titan with laser weapons according to the effect.


    Laser weapons and live ammunition weapons are two different weapons, and their use is more similar to holding a flashlight to illuminate the target, rather than shooting a light mass like a bullet as shown in many movies.


    Therefore, the use must be different from the existing weapons. The military needs to actually test and study how to use this new weapon.


    However, these are not the contents that Chen Xin needs to be responsible for.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Two assault vehicles equipped with laser weapons were soon sent to the front line and handed over to the military.


    The military was really surprised that Chen Xin really provided new weapons so quickly. Although they asked Chen Xin, they just had a try and didn''t really place their hopes on new weapons.


    After all, they also know that this requirement is very inhumane and a little whimsical.


    The research and development of a new weapon, from design finalization to trial production, and then to actual combat testing, and finally determine mass production, usually takes several years.


    It is possible for the military to change a rifle for ten years, eight years and three months to come up with a new weapon that can be put into actual combat, even if it is just an engineer shovel.


    This is why Chen Xin has created too many miracles before, which makes the military have such an idea.


    But even so, the military is still ready without new weapons. They all feel that even if Chen Xin can come up with new weapons that meet the requirements in three months, he may not be able to enter mass production and catch up with the subsequent counter offensive and suppression operations.


    But now Chen Xin has done it, and the military has undoubtedly been greatly shocked.


    However, the way soldiers think about problems is different from ordinary people. For them, there is no new weapon and whether they are prepared for new weapons. With new weapons, they naturally have to make adjustments around new weapons.


    The two sample vehicles were tested quickly, and the military quickly found out the effects of different types of laser weapons on the two vehicles.


    The military is undoubtedly satisfied with the damage effect of the laser weapons on the two sample vehicles. Although it seems that it is not much different from the damage caused by large caliber bullets or small caliber machine gun shells, it is obvious that there is an essential difference between the two.


    Laser weapons have well solved the problem of bomb jumping, which has been bothered by the military, and the problem of tunnel collapse caused by shell explosion, and met the requirements of the military for underground tunnel operations.


    Therefore, the military immediately organized a group of front-line commanders and fighters with rich combat experience to study tactics and use methods. On the one hand, it also returned the test results to Chen Xin and put forward some improvement suggestions.

 Chapter 803

    Three months passed quickly.


    The excavation operation is going very smoothly. More than 90% of a deep underground tunnel has been completed, and only the last short distance can open up the nest of alien creatures under the ground.


    The military is also making intensive preparations. The latest laser assault vehicle has been equipped to the team that will be put into the attack as the leading force, and has explored a set of use methods and formulated relevant tactics for it in the past three months.


    Although this laser assault vehicle is only as powerful as a heavy machine gun, after it is actually put into use, the military has concluded that laser weapons are much easier to use than machine guns.


    Compared with the crane machine gun, which needs to carry a large amount of ammunition and may cause accidental injury due to bullet jumping in use, the laser weapon completely avoids these shortcomings, can provide continuous and stable fire support for the army, effectively suppress alien organisms, and greatly improve the combat efficiency of the army.


    After all, when a heavy machine gun is used in an underground tunnel for an hour, it can shoot tens of thousands of bullets. Even without considering the accidental injury caused by bullet jumping, tens of thousands of bullets need to be towed by a truck.


    Now with laser weapons, the consumption of this part of ammunition can be completely removed.


    Satisfied with the laser weapon, the military even tried to install it on the spider robot previously provided by Chen Xin to the military.


    Compared with assault vehicles, spider robots are obviously more suitable for the tunnel environment. Originally, Chen Xin also provided the military with models equipped with heavy machine guns, and the military is also very satisfied with their use.


    However, compared with the current version equipped with laser weapons, the original version of heavy machine gun is naturally less attractive.


    If the production of spider robots is not more complex and time-consuming than assault vehicles, the transformation of existing fire support spider robots is also more troublesome, and the laser weapon module should be supplied to the production of assault vehicles first. The military may want a large number of spider robots equipped with laser weapons.


    But three months is really too short. Even if the factory worked hard, the total number of laser weapons finally delivered to the army is less than 200.


    Among them, more than 100 are installed on assault vehicles, more than 50 are installed on spider robots, and the remaining dozens are used as replacement.


    Among the dozens of spare laser weapons, more than a dozen were tentatively installed on the Gongshi Titan by some thoughtful technicians. After some tests, they also had good results.


    With these laser weapons, the military can''t just wait and select the best troops. The military sent them into the underground tunnels that have been temporarily turned into defense to test the use effect of these new weapons.


    It has to be said that laser weapons do have satisfactory results. In the military test, the troops organized with laser weapons completed the operation at a much higher speed than the original attack, and cleaned up a tunnel very cleanly.


    If the military hadn''t planned to continue the attack and let them withdraw directly after the suppression, it can''t be said that this tunnel would have been attacked.


    This is undoubtedly much more efficient than the previous military''s laborious tug of war with alien creatures.


    This has undoubtedly greatly boosted the morale of the military and given them more confidence in the counter offensive plan. If they can always eliminate underground creatures with such efficiency, the military even feels that they do not need to rely on the excavation plan, and they are sure to eliminate the alien creatures underground in the Dongting Lake area within six months.


    Of course, if there are no other moths in alien life.


    But things are often expected. According to Murphy''s theorem, if a bad thing may happen, it will happen. When there is only a short distance left in the excavation operation, and the construction team expands the tunnel according to the original plan to build the forward base, the accident still happened.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    In the process of tunnel excavation, detectors have been monitoring the stratum around the tunnel to prevent the possibility of penetrating an underground tunnel or cave in the process of tunneling.


    At the same time, it is also monitoring the activities of alien organisms in the surrounding tunnels and caves to avoid tunneling and interference to the construction.


    The previous excavation work has been very smooth. Relying on a line determined by geological exploration, it completely avoided the existing underground tunnels and caves. During the tunnel excavation construction, it did not encounter the interference of alien organisms.


    However, when the tunnel excavation was only less than 100 meters away and the construction team had begun to expand the tunnel into a forward base, the surrounding alien creatures were like crazy. Suddenly, they all made crazy holes towards the tunnel excavation position, with a momentum of vowing to dig through here.


    This undoubtedly triggered the alarm. The construction team adopted an emergency plan and hurriedly evacuated all the workers. At the same time, in order to protect the precious shield machine, it was also disassembled in the shortest time and evacuated from the ground together with the evacuated workers


    It took three months to dig, but it took less than half a day to retreat.


    After the evacuation of the construction team, the army conveniently and quickly entered the tunnel and prepared for battle according to the detected alien biological activities.


    When the first worker ant body dug through the wall of the tunnel and drilled out, an invisible laser instantly shone on its head, and then fried it into a smashed watermelon in less than a second.


    Then, more alien creatures poured into the tunnel and began to attack upward.


    However, human beings have long been ready. With the help of the fire control system, dozens of laser weapons continue to shoot these alien creatures. Almost instantly, the tunnel is filled with the bodies of alien creatures, and even the offensive of alien creatures is affected.


    But these alien creatures did not stop, but constantly risked huge casualties to completely dig the tunnel, allowing more combat daughters and worker ant daughters to flow into the tunnel.


    Because the tunnel is almost a straight line, human beings naturally do not have the limitations of previous operations in underground tunnels, which are limited by the tortuous terrain and unable to give full play to the advantages of weapons. While the newly equipped laser weapons are powerful, heavy machine guns and light machine guns do not want to fall behind. They sprinkle a lot of ammunition and send death to alien creatures at the same time.


    However, for fear of collapsing the tunnel, the military still did not use large-diameter artillery and powerful explosives.


    The Anti Japanese military''s fight against the underground alien nest in the Dongting Lake area was launched when the human side did not expect it, but was ready.

 Chapter 804

    Because the war had begun, the military began to devote itself to the counter offensive, and Chen Xin was busy.


    But this time, he doesn''t have to go to the front line or take charge of all aspects of work. After all, it''s domestic. These things are being done, and the situation in Yanguo is much better than that in Europe, and there are few things to worry about.


    Therefore, although a lot of work has been piled on Chen Xin''s desk, he can still think about the defense in the Middle East after handling his work.


    The so-called Middle East refers to some areas from the eastern and southern Mediterranean to the Persian Gulf Coast, including most of West Asia except afghanistan, Egypt in Africa and the Outer Caucasus on the border with Russia.


    This area connects the three continents of Asia, Europe and Africa. Since ancient times, it has been a transportation hub between the East and the West. It is a place of "two oceans, three continents and five seas", and its strategic position is extremely important.


    In 1902, the English geographer and Geopolitician Harford mackind put forward the world island theory, which regarded the three continents of Asia, Europe and Africa as a world island, and the Middle East is the center of the world island.


    In the world island theory, whoever controls the center of the world island can then control the whole world island and the whole world.


    In the age of cold weapons, limited by the problems of transportation, science and technology and productivity, no country can control the center of the world island. However, in history, it is still an important traffic artery connecting the three continents of Asia, Europe and Africa, and this position continues to this day.


    However, with the development of history and the continuous improvement of productivity, even without the world island theory proposed by Harford mackind, this land has always been coveted.


    From the sun never setting empire of "God, I have the right" to the two superpowers competing for world hegemony after World War II, almost all the wars in this land since World War II are the mess left by the English occupation of this land and the wars provoked by the struggle between the Federation and the Soviet Union for world hegemony.


    From this, we can also see how important the strategic significance of this region is.


    For the world after the disaster, this region is still an important transportation throat. Even if you can go from Russia to Europe, and Africa has cut off all information exchanges, the Middle East still has very important strategic significance.


    After all, alien creatures can invade the Middle East from the Mediterranean. After that, as long as they cross the Arabian Peninsula and the Iranian Plateau, they will have no obstacles, whether they attack the Indian peninsula south or central Asia north.


    The only possible obstacle may be the Himalayas, known as the roof of the world, which can rely on the terrain to prevent alien creatures from moving eastward and penetrate the Qinghai Tibet Plateau.


    This situation really confirms Harford mackind''s World Island theory. Whoever controls this area can control the three continents of Asia, Europe and Africa and the whole world island.


    This is the worst case for humans.


    At present, human beings have built two important defense lines, one along the North Bank of the Mediterranean and the other across Eastern Europe. Although the southern end of the Eastern European defense line extends towards the Middle East, it only extends near the great Caucasus mountains. With the help of the terrain of the mountains, it can block the advance route of alien organisms.


    If we can''t block alien creatures on the Mesopotamian plain, once they cross the Iranian Plateau, it means that the whole Asian continent is open to alien creatures.


    Therefore, the current plan of Yanguo is to solve the problem of Dongting Lake area as soon as possible, and then use troops and resources for defense in the Middle East.


    However, there are disputes about how to build the defense line in the Middle East.


    At present, the most effective way is naturally to build a defense line in the Zagros Mountains on the west side of the Iranian plateau with the help of terrain, and then connect it with the greater Caucasus mountains of the Eastern European defense line to form a whole. If alien creatures really attack from here, they can block alien creatures on the Mesopotamian plain.


    But some high-level officials in China think it is too far to build the defense line in this way.


    They felt that Yanguo should not go so far away from the Middle East to build a defense line, but should build a defense line along the Himalayas and guard the border.


    If only in terms of the length and quantities of the defense line, there is not much difference between the Zagros Mountains and the Himalayas.


    Both are mountainous terrain, and the length of the defense line is not much different. The terrain of the Himalayas is even steeper, and the construction of the defense line is more conducive to defense.


    But if you compare the location on the map, you will understand that if you only build a defense line in the Himalayas, it can really block the route of alien creatures attacking Yanguo eastward and protect Yanguo''s own home.


    But at the same time, Central Asia and the Indian peninsula are not fortified areas for alien creatures passing through the Middle East.


    Even because the ocean surface is frozen, alien creatures can invade Southeast Asia as long as they run a little farther east.


    In Chen Xin''s view, the location of the defense line is indisputable. Repairing the defense line in the Middle East can effectively connect with the defense line in Eastern Europe, which can not only enhance the defense effect of the defense line, but also unite with allies, and make the defense line guard more regions.


    It can be said that repairing the defense line in the Zagros Mountains in the Middle East is a matter of killing many birds with one stone.


    But if the defense line is retreated to the Himalayas, the role of this defense line will be greatly reduced.


    Not to mention that the two regions of Central Asia and the Indian peninsula will directly lose their barriers. The attack of alien creatures is unimpeded. It is just that the matter of allowing alien creatures to pass through the Middle East itself has a very significant impact on the country.


    The most intuitive point is that when central Asia and the Indian peninsula are captured, the inflammatory country will face alien creatures attacking from three directions.


    This will undoubtedly greatly increase the consumption of combat for Yanguo.


    And have enemies in front and rear of the Central Asian region, and then they can continue to go up to Lucia. Lucia will face the situation of being caught in the back and belly, and it is likely to lose territory of Europe, lose the best land of their own, and even the whole country will fall into this trap.


    Chen Xin really doesn''t understand why senior management have different opinions on this matter. Is it true that some people are so short-sighted?


    Or does someone play an ignominious role and intend to seek benefits from it?


    But the problem is that alien creatures are just a group of beasts like insects. Even if human beings want to sell national interests and take refuge in alien creatures for private interests, it is impossible!

 Chapter 805

    When Chen Xin wondered why some of the top leaders chose to build a conservative defense line in the Himalayas, the military attack was quite smooth.


    Through the vibration monitoring of the underground situation in the whole Dongting Lake area, the military found that alien creatures were converging towards the end of the tunnel, so it became the center of the battlefield and the most anxious place.


    Relying on the good play of laser weapons and the unobstructed terrain in the tunnel, the army of Yanguo soon blocked the crazy counterattack of alien creatures and began to push back gradually.


    But alien creatures don''t care about casualties at all. They continue to dig the wall of the tunnel against amazing casualties, but they are burned through their heads by laser weapons at the moment they emerge.


    A large number of corpses piled up in the tunnel, even showing that the corpses of alien creatures directly blocked the channels they dug around the tunnel.


    In fact, because the top of the tunnel was not excavated, and alien creatures did not dig the tunnel from that direction, a large number of corpses piled up there directly, and even tended to accumulate upward after being filled.


    It is conceivable how many alien creatures died in this battle.


    If it''s on the ground, it''s hard to see this literally piled up like a mountain of corpses.


    But in this tunnel, even if Chen Xin initially considered the issue of military attack and enlarged the tunnel diameter to 20 meters, he still quickly filled the tunnel because of the high casualties of alien creatures.


    Even because the accumulation of corpses blocked the passage, alien creatures are constantly digging new passages along the tunnel.


    In the face of this situation, the military was also impolite. After a strong push back, it put the counter offensive forces that had been waiting for a long time into the tunnel and began to launch a counter offensive along the channels excavated by those alien creatures.


    However, although it successfully pushed back the past, the military still felt that its strategic intention had been hindered.


    Because their original plan was to dig through a large underground cave about 1500 meters underground, that is, after detection, it was determined to be the location of the nest of alien creatures, and then destroy the breeding ground of alien creatures to block their troop replenishment.


    But now, affected by the counterattack of alien creatures at any cost, it is obvious that the military can no longer continue to dig. More than 50 meters long bodies are piled up at the bottom of the tunnel, and the walls are also channels dug by alien creatures.


    Under such circumstances, it is obvious that the original strategy can no longer be implemented.


    But the military is not willing to give up the original plan. After all, this plan is much more effective than using ammunition consumption to fight each other''s breeding speed.


    But now it is obviously impossible to continue the excavation according to the original plan, and the military has to modify the immediate plan.


    Only in the face of the current situation, the military staff can only think of the continued attack of conventional tactics, relying on the advantages brought by the current laser weapons to open the situation.


    After all, even if someone plans to continue to dig down, there is no suitable excavation tool at present. It is impossible to plug the shield machine back into the tunnel and continue to dig down with the corpse that has been filled with nearly 100 meters of tunnel?


    Not to mention the problem of these bodies, the alien creatures pouring in from the tunnel wall are a very troublesome problem.


    If the troops in those passages are not fighting against the counter push, awesome strength has been achieved, and the offensive of the other side has been suppressed. The tunnel has been excavate from time to time, and now the military will even be affected.


    However, attacking with conventional tactics has another problem, that is, the problem of time.


    Even if the tunnel has reached 1400 meters underground and is only 100 meters away from the nest of alien creatures, it will take at least more than a month for the military to push back from the channel around the tunnel to attack the nest of alien creatures according to the original plan.


    This is still under the condition of smooth attack. If we take the current crazy counterattack posture of alien creatures and their hidden hands, it is almost certain that there will be any accident.


    Under such circumstances, the military had to find another way.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "What? You asked me if there was any way to let at least one object the size of a DF missile pass through the last 100 meters of soil to reach the nest of alien creatures?" Chen Xin was very surprised when asked by the military officer: "what do you want to do? You don''t want to throw a nuclear bomb?"


    For Chen Xin''s speculation, the officers sent by the military did not deny it, but replied: "this is beyond the scope of my answer."


    Hearing the officer say so, Chen Xin can only pinch his nose and give up finding the answer from the other party.


    After all, even if the military really wants to use a nuclear bomb, it is not something that ordinary officers can know. Even if the officer is involved, it involves important preparations for the use of a nuclear bomb.


    However, judging from the questions asked by the other party, the military estimates that it really has this idea.


    Instead of taking a month to attack slowly, it''s better to drop a nuclear bomb and solve the problem directly.


    From the analysis of the current situation, it will undoubtedly consume a lot of resources, precious troops and time to continue to attack with conventional tactics.


    If nuclear bombs are used, as long as they can be successfully inserted into the nest of alien creatures, relying on the power of strategic nuclear bombs is enough to solve the problem and save these consumption.


    Chen Xin put down his work, stretched out a finger and knocked rhythmically on the desk, falling into thinking.


    The officer did not urge, so he stood in front of Chen Xin, waiting for his answer.


    Chen Xin''s thinking did not last long. After all, he only thought about the possible consequences of bombarding alien biological nests with nuclear bombs, not how to break a DF missile into alien biological nests.


    "It is not difficult to transform a DF missile so that it can penetrate 100 meters of stratum, and I can do it according to the requirements of the military." Chen Xin gave a positive answer, but also stressed to the officer: "However, the consequences and impact of nuclear attack need to be seriously considered. After all, the underground of the whole Dongting Lake area are caves and tunnels excavated by alien organisms. Whether these caves and tunnels have damaged the geological structure of the area, and whether nuclear explosion will cause geological movement


    These are things that need careful consideration. If large-scale geological activities are triggered, the consequences will be unimaginable. I hope you understand this. "

 Chapter 806

    In the underground tunnel of Dongting Lake, the troops who were fighting bravely and advancing steadily received instructions from their superiors and began to evacuate orderly from the tunnel.


    "Platoon leader, what does this mean above? The position that was finally fought down gave up and retreated?" a soldier operating heavy mecha asked his platoon leader while replacing the empty rocket launcher.


    As soldiers of the burning country, they have a very glorious tradition. Even in a sea of swords and fires, they will break through without frowning. Even if they know that they will die, they will spare no effort to finish the task.


    But for this army, there is one order that is the most difficult to accept, that is, to give up the position and retreat.


    For the soldiers of Yan country, their heads can be broken and their blood can flow. They can''t lose their positions! Even if the enemy flattens the whole position for several meters with bombs, even if there is only the last person in the whole company, and even if a unit bears 500% of the casualties, it will never give up the position it should stick to.


    Therefore, there is no doubt that the soldiers are emotional about the military''s sudden demand that all troops abandon the positions they have attacked during this period and retreat.


    The soldier in front of him is just a representative of thousands of soldiers.


    Facing the soldier''s question, the platoon leader didn''t explain, but said to him, "don''t ask if you shouldn''t ask. Soldiers take obeying orders as their bounden duty! Since it''s a military order, it should be implemented to the letter! Those who understand should be implemented, and those who don''t understand should also be implemented!"


    "I know! But I just can''t figure it out!" the soldier was not convinced by the platoon leader''s words, but still argued unconvinced: "how many sacrifices have we made along the way? Lao Li, Dunzi and Xiao Zhao, seven people have been sacrificed in our platoon alone!


    There are so many disabled comrades in arms that they may never be able to return to the battlefield again! The positions we fought down were abandoned and we retreated. I have no face to see them! "


    "Obey orders!" the platoon leader actually doesn''t understand why to retreat like the soldiers in front of him, but since the superior has explained the task, as a soldier, he has to obey orders.


    The army has never been a place where people and conditions can be stressed.


    As he said just now, for orders, those who understand should be executed, and those who do not understand should also be executed.


    The army will never explain to you because you don''t understand an order, nor give up executing an order because a soldier doesn''t understand it.


    Therefore, even the platoon leader himself did not understand why he received the order of full retreat, but he still firmly implemented the military order, organized his platoon to complete the retreat, and blew up his own tunnel as required, so that the enemy could not pursue along the tunnel.


    After they withdrew from the underground along the tunnel, the soldiers who had just looked wronged suddenly noticed that at the exit of the tunnel, where the shield machine originally retreated from the underground was placed, the shield machine had been lifted, and a large missile was lying on the original position of the shield machine, A group of soldiers in exoskeletons are busy around the missile.


    "Platoon leader, isn''t that mushroom egg?" seeing the missile, the little soldier''s wronged look disappeared suddenly, and his eyes were amazing.


    "Don''t inquire about what you shouldn''t inquire about. If you really want to serve mushroom eggs, that''s military secrets! Forget the confidentiality discipline? Go back and copy the confidentiality regulations 20 times!" the platoon leader quickly stopped the little soldier from asking.


    Although at the moment he saw the missile, he guessed that it might be a nuclear bomb and instantly understood why he received the military order of full withdrawal, his integrity as a soldier made him react in an instant. The use of nuclear weapons has always been a high military secret, which is not what ordinary soldiers should inquire about and know.


    If you see it, pretend not to see it!


    With this idea in mind, the platoon leader quickly restrained the soldiers of his platoon and quickly left the tunnel. Everyone pretended not to know anything and returned to their camp.


    In addition to this platoon, more evacuated soldiers noticed the large missile, and even identified the type of missile and the ground penetrating warhead used.


    But everyone chose the same way as the platoon leader, pretending that they didn''t know anything, and with uncontrollable excitement, they returned to the camp and waited for further orders.


    Yanguo has used nuclear bombs in the Dongting Lake area before, so these soldiers have no doubt about whether the military will use nuclear bombs. If they want to use nuclear bombs, they will not be allowed to stay in the camp. They must take nuclear prevention measures.


    Sure enough, soon all the troops received further instructions and began to withdraw from the temporary camp now built on the surface of Dongting Lake and returned to the semi YONGGU camp before the counter offensive.


    And in accordance with the requirements of anti nuclear, chemical and biological weapons, we have made preparations for response.


    After everyone completed the preparations, the DF missile prepared by the military and upgraded by Chen Xin and equipped with ground penetrating warheads was also loaded on a flat car and pushed into the tunnel.


    After the missile was pushed into the tunnel, the last group of staff responsible for launching the special missile also evacuated by helicopter.


    The whole Dongting Lake area seemed to be evacuated at once, and no one remained.


    Not only the troops who had invaded the tunnel before, but also the underground tunnels from other directions, and even the troops responsible for holding on were withdrawn.


    After all, this time the military is using a strategic nuclear bomb of the megaton equivalent level, and the tactical nuclear bomb used before is not at the same level. Moreover, although the military''s purpose this time is only to use nuclear bombs to destroy the nests of underground alien creatures and block their troop replenishment, it has not continued its original plan to use nuclear bombs to blow up underground tunnels in the Dongting Lake area, The idea of solving the problem once and for all.


    In fact, the military has really looked for geological experts to calculate in this regard. The time was just before the geological survey of the whole Dongting Lake area for the excavation plan.


    After receiving the geological survey report and the distribution of underground tunnels in the Dongting Lake area, the military handed these data to relevant geological experts for very comprehensive and detailed calculation and calculation.


    But at that time, they all thought that the excavation plan would go well, and the use of nuclear bombs was only the last backup plan.


    The military only left a hand in designing the tunnel, designed the tunnel into a style that can be used for nuclear bombs, and left some backhands in tunnel construction, so that it can be used when nuclear bombs need to be used.


    Now, it''s time for these backhands to play a role.

 Chapter 807

    The missile pushed into the tunnel slides all the way to the depth of the tunnel under the push of the flat car.


    Although it is a missile, because the tunnel is not a complete branch line, it still needs a flat car to send the missile to a suitable position. It can''t ignite directly at the tunnel entrance.


    However, the military made preparations in advance when designing the tunnel. The tunnel is more than 4000 meters long and the vertical depth reaches 1500 meters. Although the last section has not been completely completed, it has also met the initial design requirements and can ensure the use of nuclear bombs.


    As for that, the military asked Chen Xin to transform the missile in order to penetrate the last layer more than 100 meters deep, so as to directly detonate the nuclear warhead in the nest of alien organisms.


    Although it sounds strange to launch missiles in the tunnel, it is not impossible to fire missiles in the tunnel as long as the tunnel is straight enough and long enough to maintain stability after the missile is ignited.


    Although it is as dangerous as driving an aircraft through a tunnel, any change and jitter of air flow may make the missile deviate from the predetermined trajectory and hit the tunnel wall, but it is still feasible after all.


    The ground penetrating missile, which has been upgraded and transformed by Chen Xinzhi, has been specially optimized in this regard to ensure that the missile can smoothly reach the bottom of the tunnel, penetrate more than 100 meters deep, and send the warhead carrying the nuclear bomb into the nest of alien organisms.


    The speed of the flat car is accelerating. Although no one drives, through remote control, this modified flat car has gradually approached its speed limit.


    "Ignition of booster rocket!" in the remote control room on the other side, I saw that the flat car had reached the predetermined depth, and the booster rocket installed on the flat car to accelerate began to work, further improving the speed of the flat car.


    At the moment, the people in the remote control room are very nervous. They have done this for the first time. They have not done any exercises before. Everything is only a scheme obtained through computer simulation. At most, they have only run several simulation tests in the virtual system of Chen Xin.


    Practice, this is the first time.


    However, the first practice was actual combat.


    Therefore, no one can guarantee that this time will be successful.


    But similarly, everyone knows that this missile launch is not allowed to fail.


    The reason is also very simple. What they shoot out is not an ordinary missile, but a strategic nuclear missile of the equivalent level of one million tons. Once the explosion position deviates, they can''t complete the scheduled task. It''s small, and other effects can''t be borne by anyone.


    However, with Chen Xin''s upgrading and adjustment of the missile, the whole launch process has also undergone several simulation tests. In theory, there will be no problem.


    Just when everyone was sweating, the staff responsible for broadcasting the situation suddenly shouted, "the missile is about to enter the horizontal section!"


    "Separation of the first stage booster rocket!" the person in charge of the launch also issued his own order loudly.


    This order was accurately executed. While the missile entered the horizontal section, the first stage booster rocket that had completed the acceleration was separated from the flat car very smoothly, and at the same time, the second stage accelerator rocket was ignited smoothly.


    According to the predetermined plan, the first stage rocket boost allows the flat car carrying the missile to pass through the first inclined downward tunnel. After entering the horizontal section, it carries out the second stage acceleration. After leaving the horizontal section, the missile itself will start ignition, and then go all the way down to the bottom of the tunnel.


    The main reason for this arrangement is that no one has fired a missile in the underground tunnel. There is also a horizontal section of the tunnel that is planned to be expanded into a logistics base in order to enable the troops to better put into operation. Naturally, it can''t directly let the missile ignite and fly by itself.


    However, when the missile leaves the horizontal section, the missile itself will separate from the flat car after ignition, further increasing the speed.


    This is also to improve the speed of the missile as much as possible. After all, in the tunnel, due to the influence of all aspects, it is impossible for the speed of the missile to break through the sound barrier. Therefore, in order to improve the speed of the missile as much as possible, we can only improve the speed of the missile as much as possible through multi-stage rocket acceleration.


    The engine of the missile itself has been adjusted. Although it will not accelerate the speed of the missile to break through the sound speed, it will also make the speed of the missile close to the sound speed as much as possible to provide more kinetic energy.


    As for how a missile that does not reach the speed of sound will penetrate the stratum more than 100 meters later, this is what Chen Xin''s transformation needs to achieve.


    In fact, the principle of the ground penetrating warhead of the missile is similar to that of the shell piercing projectile. The outer shell is made of soft material. After hitting the target, the inner shell made of hard material wrapped in the outer shell penetrates the armor or stratum with strong kinetic energy.


    However, Chen Xin adopted some brain hole designs on the missile. When the missile hits the target, the hard armor piercing warhead with a nuclear bomb inside will be hit out like a shell in the gun chamber, so that its speed can break through the sound speed and obtain enough kinetic energy to penetrate more than 100 meters of the formation.


    Of course, this design is not available on serious missiles. It is entirely Chen Xin''s idea of relying on his brain hole, and then forcibly upgraded it with the system upgrade function.


    After all, no missile will consider launching in a tunnel, let alone how to make a nuclear warhead penetrate more than 100 meters deep and detonate more than 1500 meters underground.


    As for why we should accelerate the missile after Chen Xin''s upgrading and transformation can penetrate a warhead more than 100 meters deep, it is in order to enable the missile body to penetrate the pile of corpses dozens of meters long deposited at the bottom of the tunnel.


    Of course, these corpses are not as hard as the stratum, but the gap between a large number of corpses and the softness of the corpse itself are excellent cushioning materials. If the missile can not accelerate to a certain extent and forcibly penetrate these corpses, the missile will get stuck in these corpses.


    In this way, even if Chen Xin''s upgraded warhead can penetrate the formation, it will also be affected, lose a lot of kinetic energy, and may even fail to penetrate the formation.


    With the support of these measures, the missile finally plunged into the bodies at the bottom of the tunnel, penetrated the layers of bodies with strong thrust and reached the bottom of the tunnel.


    "Bang!" a steel needle like ground penetrating warhead, which is much thinner than the missile, shoots out from the top of the missile and instantly penetrates into the stratum.


    Then... The people in the remote command room felt the earth shaking under their feet.

 Chapter 808

    Through the satellite that has resumed operation, it can be clearly seen that a large number of cracks appear on the ice surface of the whole Dongting Lake area, and even the lake surface bulges with the naked eye on the satellite map, and then the whole collapses.


    The explosion of a megaton nuclear bomb should not have had such a great impact on the thousands of thick strata.


    But alien creatures have eaten this land full of tunnels and caves, just like a steamed bread with cavities inside. The impact of the explosion will not only pass along the stratum, but also impact upward along these tunnels and caves.


    So the whole stratum was jacked up, and after being jacked up, it quickly collapsed due to the destruction of geological structure.


    Although such violent geological activity is not a natural earthquake, it still makes the surrounding areas feel strong vibration, and even buildings in many cities collapsed.


    Fortunately, the residents of the surrounding cities have migrated as early as when alien creatures began to invade. At present, soldiers are stationed around, and solid fortifications and barracks are built, which has not caused much impact.


    Such drastic topographic changes have also changed the original topography of the whole Dongting Lake area.


    Junshan island in the middle of the lake sank completely this time. With the collapse of the stratum, it was originally the exit of the underground tunnel excavated by alien organisms. The natural collapse was also the most serious. The whole island sank together with a large area of the surrounding lake, making the whole Dongting Lake look more like a big pit after drying up.


    Even though the military had made many calculations before the operation and simulated it with the help of Chen Xin''s virtual system, the collapse degree of Dongting Lake area still exceeded the original expectation.


    The average subsidence of the whole lake area is more than 50 meters, and even more than 100 meters in some serious places!


    It will be three days before the whole Dongting Lake area stabilizes and there is no more collapse.


    Flying over Junshan island by helicopter, looking at the completely unrecognized island at his feet, Chen Xin said with emotion: "what amazing damage! We fought with alien creatures for nearly two years, and the whole Dongting Lake has not been damaged like this. As a result, it is only a nuclear bomb, and the mountains and rivers change shape in just three days..."


    "It''s mainly that alien creatures have eaten away the bottom of Dongting Lake. Before geological scanning, more than half of the 500 meter deep strata under the whole lake area are tunnels and caves excavated by alien creatures. How can this not collapse?" a scientific researcher accompanying Chen Xin heard Chen Xin''s sigh and sighed.


    As he spoke, he looked at Junshan Island, which was almost unrecognizable under his feet, and asked Chen Xin, "I remember academician Chen, you had an ecological planting farm on Junshan island before, didn''t you?"


    "Yes, before the alien invasion, Professor Li and I solved the problem of establishing an ecological agriculture system under greenhouse conditions. We originally planned to re-establish agricultural production in the original Junshan farm. Who would have thought that the alien invasion broke out soon after it was put into use, and the whole ecological agriculture production area was abandoned." Chen Xin lamented when he mentioned this matter, At the beginning, he and Professor Li spent a lot of effort on ecological agriculture. They originally intended to solve the problem of domestic food production, but they didn''t expect to encounter the invasion of alien organisms, and their efforts were almost wasted.


    But when it comes to ecology, Chen Xin suddenly sounded something. He couldn''t help looking at the Dongting Lake at his feet and said with worry: "the whole Dongting Lake has become what it is now. I don''t know how much impact it will have..."


    "Impact? Academician Chen, are you talking about the impact caused by the geological collapse?" the researchers heard Chen Xin''s concern, smiled and said: "don''t worry too much about this. The Academy of Geological Sciences has calculated that the nuclear explosion will not cause too much damage to the geological structure of Dongting Lake area. On the contrary, the geological structure tends to be stable because of the collapse of those tunnels.


    In addition, the Dongting Lake area itself is not in the earthquake zone, and there will be no geological disasters after that. At most, there are some small-scale geological collapses. "


    However, Chen Xin shook his head and said with a worried look: "I''m not talking about the geological impact. Although the nuclear bomb explosion did cause geological collapse, it also destroyed the original geological structure and released the energy accumulated by possible earthquakes. There is little possibility of large-scale earthquakes in the future.


    What I''m worried about is the ecological problem. Although I can''t see any impact now because of the temperature, in the future... The whole Dongting Lake will become like this, which will have an impact on the ecology... "


    When Chen Xin said this, he suddenly laughed at himself, shook his head again, and said helplessly: "this cold winter has not been known to last for many years. The earth''s ecology has long been destroyed. In the future, even if the ice and snow melt, the ecological system will be re formed. The impact is meaningless. I''m really worried about it!"


    For Chen Xin''s worries and self mockery, the researchers comforted him: "academician Chen, you are also thinking about the future of the country and mankind. How can you be groundless? Moreover, even if the ecological environment will be re formed in the future, the collapse of Dongting Lake area will also have an impact on the ecological environment in the future.


    Although this is a very distant thing from us and may not need to be considered until hundreds of years later, it is better for us to consider this problem now than to leave it to future generations, isn''t it? "


    Hearing the consolation of the researchers, Chen Xin smiled and said nothing more.


    The plane circled the whole Dongting Lake, and the impact of the nuclear bomb was presented to Chen Xin.


    After understanding the current situation of Dongting Lake area, Chen Xin ordered to return.


    Returning to his laboratory, Chen Xin input all the data and data he saw and collected after the nuclear explosion in these three days into the virtual system, and began to calculate and deduce the impact of the nuclear explosion.


    Chen Xin calculated and deduced that in addition to the impact of the nuclear explosion on geology, environment and future natural ecology, he was most concerned about whether the nuclear explosion completely eliminated the underground alien organisms.


    Although according to his prior calculation, this nuclear explosion is enough to destroy the underground nests of alien creatures and most alien creatures, and even if there is a missed fish will be crushed to death in the geological collapse, no one can guarantee that all alien creatures will be destroyed by this nuclear explosion.


    Therefore, in order to seek peace of mind and get a result, Chen Xin still hopes to get a more accurate answer through the calculation of the virtual system.

 Chapter 809

    When Chen Xin calculated through the virtual system whether the damage caused by the geological collapse caused by the nuclear explosion could empty the underground alien creatures, the military was also paying attention to this matter.


    However, the military''s approach is different from that of Chen Xin. Instead of collecting data and data for analysis, they used various instruments to re set up a monitoring network in the Dongting Lake area to detect the underground situation.


    This is also the experience found out in the battle with alien creatures before. When alien creatures dig and move underground, they will produce vibration and leave various traces. The activity status of underground alien creatures can be detected through the detection of instruments and equipment.


    The existing human technology is enough to do this. If we didn''t do so before, there is nothing worth testing underground. Now that we know that there are alien creatures underground, we naturally need to use these equipment to avoid hitting alien creatures again if there is a real problem.


    Relying on this detection network, the news is very encouraging. At least within the detection range of the current instrument, there is no trace of alien biological activities.


    This reassures both the military and the national high-level. Although the entire detection network is still left in case, and many troops continue to be stationed in the Dongting Lake area, at least now the large military that was originally assembled can be used as another way, and the military production that was originally in full operation can also be adjusted to the people''s livelihood for the time being.


    The past two years of fighting with alien creatures have had a great impact on the people''s livelihood in our country. Although it will not deprive ordinary people of food, it has also reduced the living standards of many people.


    This is also a matter of no choice. After all, it is a large-scale war. It is impossible for the state to sustain it unless it tilts its resources and strength to the military industry.


    But the subsequent decline in people''s living standards is also a necessary price. It can only be said that there will be pain brought about by the war.


    However, although the state intends to tilt its resources and forces to the people''s livelihood, it can''t move too much or too fast. Although the military industry doesn''t need to operate at full capacity, it still needs to be maintained.


    On the one hand, this is because Europe is still fighting against alien creatures, and China needs to support Europe.


    At the same time, it is to defend the second front that may be opened up in the Middle East.


    Although a small number of people in China are opposed to continuing to support Europe and building a defense line in the Middle East, and even the top level has different opinions, the top level has unified their opinions and decided to continue to support the European battlefield. At the same time, they have joined hands with Lucia to extend the defense line in Eastern Europe to the Middle East and block alien creatures on the Mesopotamian plain.


    Of course, due to compromises in some aspects, while unifying internal opinions to build a defense line in the Middle East, the high-level also proposed that regional investigations must be carried out in the Mediterranean, Africa and the Middle East first. Only when it is ensured that alien creatures do not invade the Middle East can a defense line be built in the Middle East, otherwise a defense fortification will be built in the Himalayas.


    In fact, this is not an excessive requirement, and there is no problem strategically. After all, if aliens have begun to march into the Middle East and humans want to build the defense line, they must use a large number of troops to block the attack of aliens, so as to buy time for the construction of the defense line.


    This is just like the situation in the Dongting Lake theater at the beginning. The flesh and blood of the army is used to resist the attack of alien creatures until the defense line is established.


    However, this will undoubtedly cause the army to bear considerable losses, and foreign operations are no better than domestic ones. The support in all aspects of supplies, sources of troops and military supplies will be inferior to domestic ones, which will undoubtedly lead to greater casualties and losses.


    If you are fighting at home, you don''t have to say anything. It''s your duty for soldiers to protect their homes and defend their country.


    But to shed blood and sacrifice abroad, we have to bear unnecessary sacrifices because of the restrictions of the foreign environment. Even if we are also defending our country, some people will still have some ideas.


    On this point, the military and high-level consultations several times, and finally came to the current compromise plan and made two preparations.


    The regional investigation of the Middle East was launched soon after the situation in the Dongting Lake area stabilized.


    A light land carrier set out from home and headed for the Middle East, where it will conduct detailed regional investigation to find out the situation.


    As for China, a series of adjustments are being made to gradually turn the country from the wartime state of going all out to the normal state, and prepare various materials and building materials for the construction of the future defense line.


    At the same time, the two design teams should also formulate defense construction plans according to the situation of the Middle East and the Himalayas.


    In short, although the war in the Dongting Lake area is temporarily over, there are no fewer things.


    It can even be said that after the war, there are more things we need to be busy.


    However, fortunately, materials are constantly imported into China from Europe. With the further stability and improvement of the situation in Europe, the total amount and types of these materials continue to increase, making the freight routes between China and Europe more and more busy.


    After careful consideration, lucians put forward the idea of restoring the railway line for the sake of material transportation and strategic support.


    This idea was supported by the European side. After careful study and judgment, the Chinese side also agreed to the plan and provided nuclear powered locomotives as support.


    Although the speed of freight trains is much slower than that of freight land ships, the strong power of nuclear powered locomotives can provide much stronger carrying capacity than that of freight land ships.


    And with such a long railway line, there can''t be only one train.


    It can be said that once the railway line is connected, the connection between Europe, Lucia and Yanguo will become closer, and the material distribution among the three will become smoother.


    This will be a great help to combat the invasion of alien organisms.


    Especially after that, Yanguo also plans to build a Middle East defense line. With this railway, the transportation of various materials will be much more convenient.


    Therefore, China''s domestic railway departments are busy. In addition to maintaining the huge domestic railway network, they also have to connect with foreign countries to prepare for the connection of the Asia Europe railway, which really makes them have some separation and lack of skills.


    While everyone was busy, Chen Xin received an invitation from Jianning railway factory to visit the production of the latest nuclear powered trains.


    Considering that the nuclear powered train is bound to become an important means of transportation in the future, Chen Xin naturally attaches great importance to this matter.


    But when he left for Jianning railway factory, he took Qin LAN and Mo Qingyan with him.

 Chapter 810

    In Jianning''s train factory, Chen Xinzheng held a meeting with the people from the factory.


    The content discussed at the meeting was still about the manufacturing and design of nuclear powered locomotives. In addition to the railway passenger transport that the country plans to gradually restore at present, Chen Xin and his colleagues mainly discussed the preparation of train sets after the connection of Asia Europe railway line.


    "At present, the most important demand for the Asia Europe railway line is the demand for freight logistics. Therefore, the most needed freight cars are general container trucks, gondolas for bulk goods, refrigerated trucks for frozen food, hopper cars for transporting coal and grain, tank cars for transporting gasoline and other liquids." a staff member is holding a report, Explain to the participants: "among them, the demand for container trucks is the largest, hopper trucks are also in great demand, others..."


    The content of the staff is quite lengthy, and involves many professional related issues. Others attending the meeting may listen very attentively, but for Chen Xin, he just listens to these contents, most of which are not directly related to him.


    This undoubtedly led him to listen a little distracted and think about the situation in Europe.


    Chen Xin undoubtedly knows more about the situation in Europe. After all, most of the goods that Europe can provide to China are the output obtained under his own operation.


    At present, Europe mainly imports various ores, crude oil and other industrial raw materials, while domestic exports to Europe are mainly foreign trade ordnance, some grain and living materials.


    In the past, land cargo ships went from China to Europe. When loading, they mainly used freight containers, but when they came back from Europe, it was difficult to load the goods in containers.


    After all, most of the ore is in bulk, and it is easy to damage the container when it is loaded in a container.


    Therefore, the practice at that time was to preliminarily smelt the ore, refine it into ingots of raw ore, and then load them into containers.


    But even so, it is still very inconvenient. Chen Xin had to design a universal container to solve the problem.


    As for the oil products produced after the Beihai oil field resumed work, it was also faced with the same problem. Fortunately, at that time, the output was not high, most of them were still supplied to the logistics needs of the European defense line, and only some of them were transported back to China after being loaded in barrels.


    However, barrel loading transportation undoubtedly greatly increased the transportation cost and reduced the transportation volume. If the transportation volume was not really small at that time, Chen Xin wanted to be two land ships for oil transportation and specially transported oil products home.


    But now... Listening to the introduction of the staff, it seems that it is going to be transported by oil tanker.


    Chen Xin feels that he can''t deny it.


    In terms of transportation, of course, tank cars can be used to transport oil products, but it is best to transport refined oil, because the transportation volume of tank cars is too low when used to transport crude oil.


    Generally, the load of a common tank car is about 50-70 tons, and the volume is about 50-70 cubic meters. Even if a train is divided into 100 cans, a train can pull thousands of tons of refined oil.


    Although it sounds a lot, it''s not much. Even if the largest 120 cubic meter long tank car is used, it can pull more than 10000 tons.


    And obviously, it''s impossible for a train with more than 100 cars to hang all tank cars.


    Therefore, relatively speaking, it is still the ship, a means of transportation with a large volume, which has a larger capacity and is more cost-effective.


    This is also why in the past, oil pipelines were used more than trains in the transportation of crude oil and refined oil, in addition to oil tankers.


    Thinking of this, Chen Xin suddenly felt that he might be able to reuse those oil tankers. Anyway, they are now like other ships. Most of them are frozen in the port. If no one cares, they may not be cared for for for hundreds of years, or they may simply be disassembled into waste steel.


    However, when Chen Xin was thinking about these problems, the staff suddenly talked about a topic that interested him.


    "According to the requirements of Europe, they hope to open passenger trains with China. Although the state has not promised this, the Ministry of Railways asked us to come up with a feasible design scheme." the staff introduced it to the participants.


    Hearing this, Chen Xin asked, "do Europe want to open passenger trains? Do they want to escape?"


    "We don''t know. The Ministry of Railways just asked us to come up with a design scheme for passenger trains." the staff was curious about this question, but obviously he couldn''t answer it.


    Chen Xin himself can answer this question, but he just asks with his mouth. Since no one answers after asking, he doesn''t care, so he asks another question: "Passenger train is really a problem worthy of attention. Not only the trains in Europe, but also the domestic countries have the intention to restore the passenger transport trains. Do you have a mature passenger train design now?"


    After asking this question, Chen xinlue looked expectantly at the staff of the train factory.


    Chen Xin had visited the nuclear powered train under test before, including passenger cars, but that was a few years ago. What the train manufacturer took out was only a conceptual design scheme.


    Moreover, at that time, limited by the number of nuclear powered locomotives, these nuclear powered locomotives were used closely for the transportation of important materials, that is, they used the mobile shelter composed of nuclear powered locomotives when they were used for disaster relief in the southwest, transferring victims and relocating people around Dongting Lake.


    Now several years later, Chen Xin is curious whether they have come up with a new and more practical design.


    The staff did not live up to Chen Xin''s expectations. They soon came up with a design scheme for passenger trains.


    "At present, the passenger cars we have that can be grouped with the nuclear power locomotive are mainly divided into short-distance hard seat cars and long-distance hard sleeper cars, as well as supporting functional cars. In terms of the current technical reserves, it is not a problem to come up with a feasible scheme." the staff explained to Chen Xin, In addition, various functional carriages are also displayed one by one: "these functional carriages are the results of the efforts of our researchers and designers in recent years. Considering that the requirements are for a long-distance passenger journey to Europe, more consideration should be given to the content of logistics support in train formation. After all, there is no supply for thousands of kilometers, the car can stand it, and people can''t stand it.


    In addition, we need to consider the problem of snow removal. Thousands of kilometers of railway is also a very troublesome thing in case of snow sections that are difficult to pass... "

    The meeting lasted for several hours, and it ended when it was almost time for dinner.


    After the meeting, naturally, everyone was ready to eat, but several leaders of the train factory held Chen Xin and didn''t let him go to the factory canteen with others.


    "You have other arrangements?" Chen Xin looked at the leaders of the train factory in surprise. He didn''t know what they were going to sell.


    One of the rich leaders smiled and said, "although the master of our canteen has good skills, it''s big pot dishes and the dining environment is noisy. Let''s find a quiet place and have a good chat with academician Chen."


    Hearing what the leader said and seeing that other people have the same attitude, Chen Xin can''t guess that these people are asking for something. He specially wants to find a chance to talk with him in private.


    For Chinese people, where is a better place to talk about things than at the dinner table?


    Of course, Chen Xin can see that the things you want to talk to yourself should be very important, otherwise there is no need to find a quiet place.


    So Chen xinlue thought about it and agreed. He just asked people to pick up Qin LAN and Mo Qingyan who were visiting the factory, and went to what they called a "quiet place" with several leaders.


    Instead of leaving the factory, they walked into a garage where Chen Xin visited before the meeting to display sample cars.


    "So this is the quiet place you said." Chen Xin looked at the place where the leaders were going to entertain themselves and said with a little surprise: "it''s the first time I''ve been invited to dinner in the train carriage!"


    "Haha, academician Chen, don''t leave at night. We also have luxury carriages specially designed for the special train. Academician Chen, you can experience it. After that, these carriages will organize a special train for academician Chen. It''s also convenient to go out in the future!" a leader with glasses joked to Chen Xin, but he was also a bit serious and flattering.


    For Chen Xin, the only question for him to enjoy the special train treatment is whether he needs it.


    However, recalling his previous experience of taking a special train to Lucia, Chen Xin did not reject the special train: "that feeling is good. In fact, I really like taking a train. It''s really good to have a special train!"


    While Chen Xin was greeting several leaders, Qin LAN and Mo Qingyan were also invited to the carriage. As soon as they came up, they heard Chen Xin''s voice.


    Qin LAN took Mo Qingyan''s hand and sat beside Chen Xin. He suddenly asked curiously, "ah Xin, what were you talking about just now? What''s really good?"


    "Oh, it was these leaders who said that they would let me experience the luxury carriages specially prepared for the special train in their factory. They said that they could form a special train for going out later." Chen Xin explained to Qin LAN.


    Qin LAN had also taken a special train with Chen Xin before, so he was no stranger to the special train. He just blinked and said with a smile: "ah Xin, when you want to go out, you always have something urgent, either a plane or a land ship. Do you have time to take a special train?"


    "If I think so, there are still some. After all, the special train is really comfortable to sit up!" Chen Xin smiled and explained to Qin LAN. At the same time, he also asked the two of them, "what did you see this afternoon?"


    "I didn''t see anything. I just visited several warehouses and looked at their various carriages." the answer was mo Qingyan. Perhaps it was rare to go out with Chen Xin. She seemed much more excited than Qin LAN: "I didn''t expect that there were so many patterns in the carriages of the train. There were several carriages. I wanted to go back and build a so-called creative villa for myself."


    "Creative villa? Good idea!" listening to Mo Qingyan''s words, Chen Xin couldn''t help smiling.


    However, after listening to these words, Mo Qingyan can''t really get some carriages back, and Chen Xin can''t really get some carriages for her.


    On the other hand, several leaders took the opportunity to say, "I don''t know what kind of carriages this lady likes? Academician Chen, if you have an idea, these carriages can also be compiled into a special train. It''s no problem to be a creative villa for this lady at that time!"


    "It can be!" Chen Xin heard that the other party was joking. Naturally, he was joking.


    As they spoke, the dishes were ready and served.


    Looking at the rich dishes on the table by current standards, as well as the service personnel who voluntarily withdrew and the closed carriage door, Chen Xin''s smile converged, looked at several leaders and asked them: "There must be something wrong with your warm hospitality. As the saying goes, people must ask for something under courtesy. You might as well say something directly, otherwise I won''t be at ease!"


    Although Chen Xin can see that these people want to talk while eating and talk until the atmosphere is harmonious and warm, Chen Xin is still not used to this.


    Hearing Chen Xin''s direct question, several leaders were stunned, but after looking at each other, they quickly unified their opinions. The rich leader said, "academician Chen, is it true that the country wants to build a defense line against alien organisms in the Middle East?"


    "Why are you asking?" Chen Xin was stunned when he heard this question, but soon picked up his chopsticks and took some vegetables to Qin LAN and Mo Qingyan. Then he continued: "there is still no shadow. Don''t catch the wind."


    Seeing Chen Xin''s attitude, several leaders suddenly showed an expected expression on their faces. The leader wearing glasses hurriedly said, "academician Chen, don''t get me wrong. We don''t want to inquire about state secrets. Just if we want to repair the defense line, we must transport a large number of materials, and the demand for train skins will be greatly increased at that time.


    We also want to make some preparations for this matter in advance. After all, if we can confirm the news in advance, we can adjust the production plan in the factory and make arrangements in advance to avoid being in a hurry, can''t we? "


    Faced with the inquiries of several leaders, Chen Xin slightly tilted his head, picked up a sparerib on the table and put it into his mouth. Gu said to his left and right: "this sparerib is good! Are there still pigs in China? Do you need special carriages to transport it? The main transport capacity of the railway is distributed to raw materials. It''s rare that you can find a way to squeeze out the transport capacity to these food supplies!"


    Hearing Chen Xin''s words, several leaders were stunned, and then quickly responded. They no longer continued to ask this topic, but enthusiastically prepared dishes for Chen Xin, and said: "we use refrigerated carriages, which are transported from Guangdong Province. We don''t boast. Our factory still has advantages in producing these food material transportation carriages!"


    Seeing that several leaders stopped asking about the repair of the defense line and boasted about their various fully functional carriages, Chen Xin knew that they understood what he meant, so while eating vegetables, he smiled and asked questions about the production of several carriages. Several leaders also answered enthusiastically. For a moment, the guests and hosts were happy.

 Chapter 812

    In the evening, at the request of several leaders, Chen Xin decided to stay and experience the so-called luxury carriage specially prepared for the special train.


    It has to be said that these carriages are really luxurious. In a sense, they are not even like train carriages, but more like luxury suites in high-end hotels.


    In addition to the corridor by the window on one side, the other parts of the whole carriage are a large suite, with a series of facilities such as living room, bedroom, bathroom and toilet, and even a small terrace and a study that can see the outside.


    The floor of the whole suite is covered with soft carpet, which will feel very comfortable even if you step on it barefoot.


    The walls of the room are clean and beautiful. Modern design and built-in lighting make the room look soft and warm, giving people a warm feeling.


    This made Qin LAN and Mo Qingyan very satisfied. They rushed to the sofa in the living room and looked unwilling to get up.


    Chen Xin looked at the two people like this. He just spoiled them and smiled. He went to the bar and poured himself a glass of water.


    Although the food was delicious, Chen Xin still felt thirsty after drinking some wine.


    He sat down on the high foot in front of the bar. Chen Xin looked around the whole room. He didn''t need much analysis to judge that this luxury car was specially prepared.


    After all, as a sample, the carriage is also well prepared. It is like a luxury suite that can receive guests at any time. It can be used at any time, not just for display.


    This also makes Chen Xin feel a little strange. What is the purpose of the train factory to produce this kind of luxury carriage.


    According to the current situation of the country, this luxury carriage pursuing enjoyment should not be produced. Even the special train for senior leaders or important people should be similar to the special train he took to Siberia last time. It is not a problem to have a separate room, but the whole carriage is a room, or this kind of luxury decoration, It''s too extravagant and wasteful.


    However, this is not the focus of Chen Xin''s attention. Chen Xin is more concerned about where they know that the Middle East needs to build a defense line than why train manufacturers produce such luxury cars?


    At present, this matter is only limited to high-level discussion. It is still uncertain whether to build a defense line in the Middle East or in the Himalayas. The whole matter can be regarded as a state secret. How did these leaders of the train manufacturing plant hear about it?


    The people above the Ministry of Railways revealed it to them? It''s possible. After all, trains will be used in all aspects of railway transportation, and the demand for nuclear powered locomotives and various carriages will undoubtedly increase. In this case, it''s not uncommon to give people in the train manufacturer a gas in advance.


    Of course, there is another possibility, that is, the state is preparing for the construction of the defense line in the future. As an enterprise involved, the train manufacturer knows that it will build a defense line and need a lot of materials. This kind of thing also makes sense.


    But even if there is reason to explain why they know about it, Chen Xin still feels that such matters related to state secrets should not be so easy to leak out.


    However, while he was thinking about these problems, Mo Qingyan, who was lying on the sofa, suddenly looked up and asked Chen Xin, "ah Xin, what did those leaders ask you just at dinner?"


    "For a matter that is still a state secret at present, they want to make some preparations in advance, so they ask for some information from me." Chen Xin explained, but did not elaborate.


    Mo Qingyan didn''t ask again when she heard Chen Xin say so. She and Qin LAN knew that many of the work involved by Chen Xin belonged to state secrets. They shouldn''t know or inquire.


    At this point, long ago, someone specially approached them, told them about it, and emphasized the confidentiality regulations.


    Mo Qingyan didn''t continue to ask, but when she interrupted, Chen Xin didn''t want to continue thinking, so she stood up and walked to the bathroom of the room: "I''ll take a bath. Do you two want to take a bath?"


    "I don''t have clothes to wash or change!" Mo Qingyan hesitated when she heard Chen Xin''s proposal to take a bath. "I said I would go back at night. I thought I didn''t need to spend the night, so I didn''t bring clothes to change."


    Qin Lan said indifferently, "what''s the matter? I''ll change it when I go back tomorrow. I''m not dirty. Even if you don''t take a bath, do you still have to wear it for another day?"


    When Qin Lan said this, Mo Qingyan no longer insisted, so she took the initiative to get into the bathroom than Qin LAN.


    Looking at Mo Qingyan''s move, Chen Xin and Qin LAN looked at each other and laughed.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    After taking a bath, the three leaned against the sofa and chatted.


    Qin LAN removed her prosthetic limb and is maintaining it. After she broke her hand, it has become her daily habit.


    Noticing the prosthetic limb on Qin Lan''s hand, Chen Xinshun took it and examined it for her.


    This prosthetic limb is still the one Chen Xin made for her at the beginning. It has been used for several years, and many places have been worn badly. Even the red paint sprayed by Chen Xin''s evil taste at that time has been worn almost. It looks like a very old prosthetic limb.


    However, Qin LAN is obviously well maintained. The prosthetic limb is in good condition. After Chen Xin''s inspection, he found that there are only minor defects such as aging and wear of parts.


    However, even so, Chen Xin can''t help feeling guilty about Qin LAN. After all these years, he forgot to change Qin LAN for a better prosthetic limb.


    Thinking of this, Chen Xin knocked on his forehead. The watch on his wrist turned into nano molecules and quickly wrapped Qin Lan''s prosthetic limb. When maintaining and adjusting this prosthetic limb, he also asked Qin LAN with regret: "I''m really negligent. Alan, have you used this prosthetic limb for several years? Let me make another one for you. Do you have any requirements?"


    "Hmm? How can you say this? I use this prosthetic limb very smoothly!" Qin LAN looked at Chen Xin strangely and didn''t understand why he suddenly mentioned this, but she smiled and said: "It''s just that some parts are aging. Ah Xin, if you have time one day, just change the parts for me. There''s no need to make a new one. You''re so busy with your work that it''s not worth wasting time for such a small thing."


    In Qin Lan''s opinion, Chen Xin''s work is very important to the country. He really doesn''t need to bother him with these little things.


    However, Chen Xin felt more sorry for this. He was moved by Qin Lan''s understanding and couldn''t help hugging her and Mo Qingyan

 Chapter 813

    When Chen Xin, Qin LAN and Mo Qingyan woke up the next morning, packed up their personal hygiene and prepared to leave, Qin Lan''s prosthetic limb had been replaced with a brand-new prosthetic limb.


    From the appearance, the new prosthetic limb is no different from the real arm. Even Qin LAN feels that this is the hand she lost.


    But this is still a mechanical prosthesis, but the surface has been camouflaged enough, so it looks like a real arm.


    For this prosthetic limb, out of the idea of making up for Qin Lan''s debt, Chen Xin spent a lot of effort. He not only made the prosthetic limb the same as the real arm, but also installed sensors all over the whole arm on its surface, so that the prosthetic limb can have the same touch as the normal arm.


    Moreover, the flexibility of the whole hand has been greatly improved, which Mo Qingyan and Chen Xin both experienced last night.


    "Ah Xin, is this......" looking at his new prosthesis, Qin Lan was very happy, but still a little embarrassed: "I don''t mean I don''t like it. I just think you don''t need to spend so much time on such a small thing. Your energy and time should be spent on work..."


    "Why do you say this? Do we need to say this before?" Chen Xin stroked Qin Lan''s hair and smiled at her: "it''s just a little spare time. It''s nothing, and I think I should spend more time with you, isn''t it?


    And you don''t need to be so tangled. It''s just a small thing. If you always care about these small things, you won''t be like you! I still prefer the tigress who threw me in bed before, not the little cat now! "


    The last sentence, Chen Xin whispered close to Qin Lan''s ear, but it still made Qin LAN blush.


    But this also made her worry less. When she hammered Chen Xin directly, her face became relaxed, and there seemed to be a feeling of letting go of something.


    Chen Xin noticed Qin Lan''s emotional change. He smiled to himself and laughed at himself. He had never found Qin Lan''s personality change in recent years, which had to be said to be a great negligence.


    Although busy work is an excuse. After all, he spent a year in Lucia and Europe respectively and didn''t spend a lot of time with Qin LAN, but Qin Lan was the person next to him in the final analysis. He didn''t even notice this change. In some aspects, Chen Xin really didn''t care enough.


    Mo Qingyan on one side is also happy when she looks at Qin Lan''s emotional changes. Although she says that Qin Lan''s personality changes have no problem in her opinion, she doesn''t want her good friends and sisters to embarrass herself and suppress her true feelings all the time.


    Now Qin LAN can put down some burdens, which is undoubtedly a good thing for her.


    This also makes Mo Qingyan feel good. After holding Chen Xin''s hand, she always wears a smile on her face.


    Even the leaders who came to see Chen Xin off noticed the full smile on Mo Qingyan''s face.


    However, this is not the focus of their attention. Compared with the people around Chen Xin, they pay more attention to Chen Xin himself.


    Of course, out of the traditional human and worldly sophistication, people around Chen Xin such as Mo Qingyan will not be ignored, and even in some ways, they are more flattering than Chen Xin himself.


    Of course, these are not things that can be put on the table, so several leaders remained polite, courteous with Chen Xin and seeing Chen Xin off.


    On the way to be polite to these leaders, Chen Xin asked the question that made him care: "what idea did you design and manufacture the luxury carriage? From a practical point of view, shouldn''t it appear?"


    Hearing Chen Xin''s question, several leaders were stunned. One of them hurriedly explained with a smile: "Academician Chen, you misunderstood. In fact, the luxury carriage is actually a kind of goods. It''s not so much a carriage as a built luxury suite. It''s just made into a carriage, or we made it to entertain important guests like academician Chen."


    "For entertaining guests? Oh, I see." hearing the leader''s explanation, Chen Xin suddenly realized that it makes sense.


    For train manufacturers, there is no doubt about their importance as one of the few remaining train manufacturers in China, which makes them have an important position in the national production plan. At the same time, important senior leaders and other figures often come to inspect them.


    Now, no more than before, there are no hotels in the city, but the leaders can''t help receiving them. The best way is to build a reception place by themselves.


    For example, the carriage where Chen Xin ate yesterday and the place where he lived last night were obviously built for this purpose.


    This kind of carriage that is clearly placed there and will not move is easy to manufacture. It is much easier than building a carriage. At the same time, it is much cheaper than building a reception place. Therefore, it is not surprising that the train manufacturer chooses this way.


    Having figured this out, Chen Xin didn''t say anything more, just joked: "can you make these carriages? What if there is really a need in this regard? For example, I want the luxury carriage to be my special train carriage now."


    "What is placed there can''t be moved, but we have made the relevant design drawings. If there is a real need, it can still be produced." the leader with glasses answered Chen Xin''s question, but the answer was very clever.


    Hearing this answer, Chen Xin nodded clearly. He knew that even if he really wanted such a luxury carriage to be his own special train, he could definitely make it with the technology of the train manufacturer.


    As for whether there are drawings as early as he said, it is a matter of different opinions.


    He was sent out of the train factory by several leaders and took the plane back to dome new town. Chen Xin couldn''t help thinking whether he could get a special train. After all, the special train is more comfortable than a helicopter in terms of comfort.


    However, this is just a thought. After all, the resources consumed by a special train are much higher than that of a helicopter.


    It is also more luxurious. After all, taking the special train not only needs to consume all kinds of supply resources to maintain, but also needs Chen Xinzhen to have that time to take the train.


    If there is really something urgent for Chen Xin to deal with, he will probably choose to fly.


    Maybe you can build yourself a land ship? This idea came out of Chen Xin''s mind

 Chapter 814

    When Chen Xin was thinking about whether he could build a land ship for himself as his "special car", the land ship sent by the military to the Middle East for investigation had arrived at his destination.


    Different from the domestic situation, the Middle East, like Europe, is still in the dark.


    This not only provides a good cover for the reconnaissance task of land-based ships, but also increases the difficulty of the task.


    After all, during the day, optical investigation can intuitively see the required information. In the dark environment, it needs the assistance of various instruments and equipment.


    Fortunately, the land ship is a special type of investigation. It is not only equipped with a large number of instruments and equipment, but also equipped with reconnaissance aircraft and reconnaissance UAVs.


    The ship is also responsible for the implementation of the investigation task of the elite in the army. With the cooperation of the two sides, the task can be said to be carried out smoothly.


    However, the Middle East region is still so large. Although the land-based ships released the reconnaissance UAV after entering the Middle East region and began a large-scale search, it will take some time for them with only one ship to investigate the whole Middle East region.


    "Captain, I suggest that we should change the investigation method and go directly to the Mediterranean coastal area for investigation, rather than the current dragnet investigation, which is too inefficient." in the bridge, a staff officer accompanying the ship put forward his own suggestions to the captain.


    The captain did not immediately agree with the staff officer''s suggestion, but thought it over carefully for a while before saying: "inserting directly into the Mediterranean can indeed save time, but our task is to find out the overall situation of the Middle East and whether aliens have launched a large-scale invasion of the Middle East, which needs a comprehensive investigation.


    Moreover, if we plug directly into the Mediterranean, we are just a reconnaissance ship with limited arms. If we encounter alien creatures, we may encounter danger. It''s better to be safe. "


    As a captain, he should be responsible for everyone on and off the ship, and ensure to complete his mission and tasks. Naturally, he should act cautiously.


    Although it is not impossible to take risks, he must comprehensively consider the proportional balance between the risks he bears and the possible gains, rather than making a rash decision in case of trouble.


    When the captain said that he wanted to pursue safety, the staff did not object. His duty was only to put forward his own suggestions to help the captain find out and make up the deficiencies, rather than to interfere with the captain''s decision when the captain made no obvious mistakes.


    So when the captain didn''t agree with his suggestion, the staff just frowned and said, "but the efficiency of our current investigation method is too low! It''s too much work to investigate the whole Middle East region after such a carpet search."


    Speaking of this, the staff officer did not forget to add: "it''s true that our reconnaissance ship is nuclear powered, but the unmanned reconnaissance aircraft we carry still burn heavy oil. The oil consumption is very fast for such a large-scale investigation every day!"


    The problem of fuel consumption mentioned by the staff officer made the captain frown slightly and asked the chief mate aside, "how much fuel do we have left?"


    "When we came out, we brought a total of 20 tons of heavy oil, which has consumed almost 30% so far." the chief mate answered the captain''s question and reminded the captain: "but so far, the areas we have scanned only account for 17% of the whole Middle East, and they are all distributed in the Iranian plateau.


    Considering the purpose of our reconnaissance mission, I also suggest that our ship go out to the Mesopotamian plain and conduct targeted reconnaissance in the Red Sea and Aleppo, Syria, which is much more effective than our carpet search. "


    The chief officer''s words are actually a kind of support for the staff''s suggestions, but the reasons and suggestions he gave are more comprehensive and stable than the staff''s previous suggestions. Therefore, after considering it, the captain adopted the chief officer''s suggestions: "In that case, we will go out of the two river basins and advance to the location of Babylon, Cuba. If there are still people there, we can also know the situation."


    "Local people? It''s unlikely that any local people will survive?" the staff on one side obviously had no expectations


    During this time, they searched most parts of the Iranian Plateau in a carpet way. Of course, the areas with cities are the key search objects, but obviously all the cities are empty.


    Such a result is not surprising. After all, this area has experienced war all year round. Although people''s livelihood is not poor, it is not an economically developed area.


    Although several oil producing countries have money, the money is mainly concentrated in the hands of the royal families and high-level officials of various countries. The gap between the living standards of the people at the bottom and the rich is so large that it is amazing.


    How much response capacity such a country can have in the face of global disasters is really a difficult question to answer.


    There is no problem for the rich to survive, but ordinary people may not be able to withstand the initial disaster.


    Moreover, in this area, from fresh water to food, these basic living materials are basically scarce. In the past, there was nothing to import for money. Now where do they import from?


    In a few years, even if there are survivors, they belong to few lucky people.


    "In short, go and have a look. Babylon is at least one of the oldest cities in this land and the capital of a country. It should not even have no living people." the captain shook his head. Although he didn''t expect anything, he decided to go and have a look.


    After all, in his opinion, although the environment in the Middle East is bad, the temperature is not as low as that in China. In the tropics, someone should be able to survive.


    The captain made a decision, and the staff and chief mate had no other opinions, so the reconnaissance ship began to adjust its course and move towards the city of Babylon, Cuba.


    At the same time, the released unmanned reconnaissance aircraft also changed the flight route and the direction of investigation.


    "Speaking of which place do you think the Red Sea and Aleppo will be the focus of alien invasion?" the captain ordered to adjust the course. Looking at the map in front of him, the captain suddenly asked the chief officer and staff a new question.


    The staff officer thought about this question and said: "I think it''s Aleppo. The Arab plateau is high on the side close to the Red Sea. From the perspective of terrain, it is not suitable for large-scale military attack. The whole Middle East region can be said to be surrounded by mountains. The only flat land is the Mesopotamian plain, and Aleppo is the only ''gap'' in the Mesopotamian plain facing the Mediterranean , if you want to invade the Middle East from the Mediterranean region, this place is the most suitable place to attack. "

 Chapter 815

    There is no problem with the staff''s judgment. Aleppo, as the only gentle area in the Middle East in the direction of the Mediterranean, is an excellent place to attack the Middle East.


    As long as we break through Aleppo, we can directly insert Syria into the two river basins at the core of the Middle East, and then control the whole Middle East.


    However, it was surprising that when the reconnaissance ship arrived over Babylon and sent reconnaissance aircraft to Aleppo, the results were surprising.


    Aliens do attack in this direction, but their attack is only equivalent to harassment.


    Compared with the attack on the Dongting Lake area of Yanguo and the current wave of attacks on Europe, the attack of alien creatures on the Middle East is hardly worth mentioning.


    They didn''t even break the coastline of Aleppo!


    This abnormal situation undoubtedly made the people on the reconnaissance ship feel very confused. When they urgently sent the situation back to China, they also contacted the locals.


    It has to be said that in the face of disaster, human vitality is still very tenacious.


    There are more than 20 countries in the Middle East, most of which rely only on underground oil to maintain the wealth of the upper class, and the life of the lower class is not very good.


    Among the disasters sweeping the world, these 20 countries were brought out alone, and no country can resist the disaster.


    However, if the forces of more than 20 countries are brought together, it is not impossible to resist the attack of this disaster.


    It''s a very simple truth that unity leads to life and division leads to death. Naturally, everyone can figure it out.


    Led by the strongest countries, we put aside the past disputes, moved the people of various countries together, and built large-scale refuge facilities, as well as other factories and other production facilities for survival, with the intention of living through this disaster by uniting the strength of all countries.


    However, the idea is beautiful, but the actual implementation is full of problems.


    Conflicts of various religious beliefs, old grievances accumulated by various countries due to war, etc


    Although all countries have maintained great tolerance and restraint in the face of disasters, various problems and conflicts still occur from time to time. In addition, the Middle East has been plagued by war all year round, and most of the people who can stay are full of martial ethics. Even if there is military pressure, it is difficult to ensure that there will be no trouble. Moreover, many times, even the armies of all countries themselves will be involved in conflicts.


    In addition, when the disaster came, the whole world fell into chaos. Countries that once relied heavily on imports fell into material shortage, which greatly affected their expected construction progress


    Finally, less than 50% of the asylum facilities that they originally planned to accommodate at least 60% of the people in various countries have been completed, that is, less than 30% of the people can have a shelter when the disaster comes


    In short, according to the information obtained from the investigation land ships of Yanguo and the local official institutions still operating in Babylon, their population is only less than 10 million.


    Before the disaster, the population of the whole Middle East was at least 490 million.


    The 10 million people who survived were concentrated in the two rivers basin and Asia Minor Peninsula, and the coast of the Persian Gulf was swallowed up by rising sea levels.


    This has also led to the fact that most of the Middle East is now a no man''s land. The remaining alliances formed by various countries are now stretched out and have lost their resistance to alien creatures.


    But fortunately, alien creatures somehow continued to attack Europe and did not launch a large-scale attack on the Middle East.


    They built a weak defense line in Aleppo, barely blocking the sporadic attacks of alien creatures, so they saved their homes.


    Having learned of these situations, the reconnaissance ship dared not neglect. While transmitting all the intelligence back to China, it was also requesting instructions for further action.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    For the situation in the Middle East, China can not help but feel some headaches.


    If all the people in this area die, the problem will undoubtedly be much simpler, but there are less than 10 million people, and they also have operating official institutions and some armies, which undoubtedly makes it difficult for the country to deal with their problems.


    Build a strong defense line in the area, regardless of these locals?


    This is not impossible, but obviously it is not in line with the habits and policies of the country.


    However, despite the 10 million people, it is also a huge burden and burden for Yanguo.


    How to deal with the problem of 10 million people has become a difficult problem in front of the senior management.


    Finally, after many discussions, the senior management decided to follow Chen Xin''s example in Europe to support the local people, help them restore order and production, and make the 10 million people produce value, rather than become a burden consuming resources.


    As for the construction plan of the defense line, some adjustments have been made.


    First of all, since the Middle East has not been attacked on a large scale, the building of a defense line in the Middle East can naturally be confirmed.


    However, considering the current situation in the Middle East, in addition to the original defense line construction plan, a side branch will be extended to Aleppo to help the local people build a solid defense in Aleppo.


    This fortification does not expect them to block the large-scale attack of alien creatures, but hopes that during the construction of the real defense line, they can drag alien creatures and block sporadic attacks.


    Although we don''t understand why aliens don''t attack the Arabian Peninsula on a large scale, it is clear that this situation can be used.


    The plan was soon established and communicated to the Lucia and European sides.


    For the plan of the Chinese people, Lucia naturally gives strong support. After all, the establishment of the Middle East defense line also seals the back of the lucians to avoid being attacked.


    Although the European side did not oppose it, it obviously did not support it as much as the lucians.


    After all, now Europe needs the assistance of inflammatory countries. In their opinion, the more assistance from inflammatory countries, the better. Naturally, they don''t want the guys in the Middle East to take a share.


    Especially before the disaster, the Middle East refugees had a bad reputation in Europe and seriously disturbed the social order of all countries, which really annoyed all countries.


    However, Europeans are not ignorant. They also understand the necessity of establishing a Middle East defense line, but they are not as supportive as Lucia.


    In the final analysis, European countries are too busy to take care of themselves. Although their situation tends to be stable on the whole, they have little spare time to do other things. They can neither get involved in nor benefit from the construction of defense lines in the Middle East, so they naturally lack interest.

 Chapter 816

    Because the situation in the Middle East is better than expected, China has adopted a different strategy in the construction of the Middle East defense line.


    Originally, Yanguo planned to transport engineering teams and construction workers from home for construction, but now that there are still 10 million people in the Middle East, it is natural to make use of these people.


    Therefore, the defense line originally built by the workers of Yanguo has become the construction method of sending technical engineers and workers from the Middle East.


    The official organizations in the Middle East greatly support and agree with this. After all, the plan given by the Yanguo people is that they build the defense line and the Yanguo provides living materials as a reward, which is a good thing for the Middle East region where people are now in decline.


    You know, in this cold era, what you fear is not that you don''t have work, but that you don''t have food.


    Agriculture in the Middle East is not developed. Although the two river basins are traditional agricultural production areas, they have also been devastated by years of war and other problems.


    Although before the disaster, officials of various countries made a wave of efforts and spent money to build some greenhouses that can be used in cold environment, it is a pity that the quantity and production capacity are limited.


    Otherwise, they would not have less than 10 million people left.


    Now they can work for Yanguo in exchange for living materials. These people struggling in hunger and cold are naturally willing to do everything.


    And this is to defend their own homeland. These Middle Easterners have no reason to oppose this.


    The first is to build the defense line in Aleppo. Although alien creatures have not launched a large-scale attack in this direction, for the sake of safety, the defense line here must be built first before the Middle East defense line can be built at ease.


    The Yanguo people began to build the defense line, while the lucians helped open up the railway line from Eastern Europe to the Middle East, transported the workers who finished the construction of the defense line in Eastern Europe to the peninsula of Asia Minor, began to build the defense line in the great Caucasus mountains, and extended the defense line to Aleppo.


    Yanguo opened up the railway line to the Middle East through Kazakhstan and began to transport construction teams, construction machinery and a large number of materials to the Middle East.


    When the two countries began to make such efforts, the local official institutions in the Middle East naturally dared not neglect. In addition to mobilizing all the troops they can mobilize now in Aleppo, they also began to organize local labor to cooperate with the construction teams of the two countries.


    Despite the slow progress of the project due to the long-term malnutrition of the local people and their lack of familiarity with the project construction, the Middle East defense line has been built as planned.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    While the work in the Middle East has been in full swing, Chen Xin did not go to the Middle East this time.


    Although Chen Xin has shown strong organizational and working abilities in his previous work in Lucia and Europe, this time the senior management did not send Chen Xin to the Middle East after taking into account the actual situation, but sent a senior official to the Middle East to coordinate the construction of the Middle East defense line.


    Chen Xin himself stayed in China this time and did not arrange any extra work for him.


    This is a rare leisure for Chen Xin. He can go home from work after completing the work at hand step by step every day. It can be regarded as a very rare thing.


    Chen Xin naturally wants to be able to go everywhere without going abroad. Who wouldn''t want to be able to accompany his parents and family at home?


    As a result, Chen Xin now goes to and from work on time every day. After returning home, he has dinner with his parents. The family is happy.


    Chen Xin enjoyed such a life very much and felt the warmth of home after a long time.


    Although I don''t feel it at ordinary times, it is really a rare warmth if I wander away for a long time, return home after a long absence, live with my family and feel the care of my family.


    Especially when Qin LAN and Mo Qingyan often come when they have time, they become more noisy as soon as there are more people.


    Although the threat of alien creatures was not completely solved, after the war in the Dongting Lake area, the overall domestic atmosphere gradually eased under the conscious control of the state.


    After fighting with alien creatures for so long, everyone collapsed too tightly. Now that the domestic war has finally ended, the country should naturally seize the time to reply to the national economy and people''s livelihood at home, and also let the people who are too tight relax. After all, if people collapse too tightly, something will happen.


    Qin LAN and Mo Qingyan, who have become more frequent since Chen Xintong came to his house, can see that the state is indeed consciously easing everything that had been running at a high speed.


    However, the country has not completely relaxed all at once, but is adjusting in an orderly manner.


    After all, the war in Europe is not over, and the threat of alien creatures has not been eradicated. We can relax, but we can''t completely relax.


    As an important scientific research department, although Chen Xin said that he left work on time every day, he did not do a lot of work. The new requirements put forward by the military after summarizing the performance of various equipment on the Dongting Lake battlefield, the cooperative tasks sent by other domestic scientific research departments, and the research of various scientific research projects of his department


    As the head of the Department, after receiving instructions from the senior management, Chen Xin naturally knows what to do. On the one hand, through reasonable arrangements, researchers and staff can reduce overtime and get a holiday to relax; On the one hand, it is also sorting all the work according to priorities as much as possible, and then completing the urgently needed work efficiently.


    For Chen Xin, such work is much easier than coordinating the affairs of the whole Europe, but it is also relatively complicated.


    If Tang Tang hadn''t been helping, Chen Xin might have to work overtime instead of getting off work on time every day.


    In addition to the departments in charge of Chen Xin, the vast majority of domestic institutions are almost in the same state. They don''t work overtime as much as possible and complete their work as efficiently as possible, so as to recover the invisible loss of the country under the state of war in the previous two years.


    Thanks to this policy of the state, Chen Xin also took time to return to his shelter.


    It was abandoned by Chen Xin when alien creatures invaded, and the original scientific research center became the front-line command of the military at that time.


    Now the war is over. Although it is necessary to maintain a rapid response force in the Dongting Lake area to deal with the possible resurgence of alien life, this front-line headquarters does not need to be retained.


    Therefore, after the military withdrew most of the military forces in the Dongting Lake area, it was returned to the Department in charge of Chen Xin.

 Chapter 817

    Having returned to his refuge for a long time, Chen Xin inevitably felt some melancholy and emotion.


    This shelter cost him a lot of effort and energy. At the beginning of the disaster, everyone was in a panic all day, hoping that the country could solve the crisis. However, he took the lead in spending all his savings to build this shelter for himself, so that he could only live under the end of the day.


    However, no one expected the subsequent changes. A person who wanted to survive had a completely different experience because of an opportunity.


    Having obtained the system, he not only greatly improved and improved his living environment, but also picked up his parents who were far away from home, and let his ex girlfriend and confidante live in together, so that he could enjoy the welfare of the whole people. Not to mention, he became an academician of the Academy of Sciences. It can be said that Chen Xin dared not think of it before.


    Not to mention what Chen Xin experienced later, the disaster relief of the southwest earthquake, Chen Xin still can''t forget those people buried under the ruins; Go to Lucia to receive the black technology during the cold war and help them rebuild the capital. The low temperature of more than 100 degrees below zero is absolutely fresh in Chen Xin''s memory; Chen Xin never felt so busy when he helped countries in Europe fight against alien creatures, resume production and stabilize social order


    During this period, Chen Xin, perhaps for his own interest or for the country, created a series of things, such as power armor, exoskeleton, machine armor, Titan, mobile base, floating warship... Which almost completely changed the current situation of the country.


    If we put it before the disaster, even Chen Xin, the original online novel writer, can''t imagine that the country will become so "science fiction" because of his influence in a few years.


    This time he revisited his hometown and returned to the shelter he had built. Chen Xin couldn''t help feeling what would have happened if he hadn''t found the system at the beginning.


    If there is no system, Chen Xin''s life will certainly not be as good as it is now, and the country may not be as it is now. He will certainly not become an academician of the Academy of Sciences. It is unknown whether he can even get back together with Qin LAN and Mo Qingyan.


    It is also unknown whether his original humble shelter can withstand the cold wave and cooling later.


    It is even possible that he could not finish his first year. Because of lack of fuel and food, he had to give up the shelter and go to the official shelter in the city to make a living, and then died of cold, hunger and disease.


    This makes Chen Xin have to sigh that he is an ordinary person, because he will get an adventure due to fate, which can come to today.


    He returned to his shelter again. Looking at it, everything here was the same as when he left two years ago, but there was a thick layer of ash everywhere. The crops in the greenhouse were in a mess because they were left unattended. Chen Xin couldn''t help feeling the passage of time.


    In the past two years, Chen Xin has been busy almost all the time, rarely able to relax, let alone feel the passage of time.


    However, when he revisited his hometown now, he still couldn''t help lamenting that things are right and people are wrong.


    Chen Xin is very satisfied with and likes this shelter that he has built himself and upgraded the system.


    Whether it is the comfort of living or the various decorations and furnishings here, Chen Xin is most satisfied with it, not to mention all the things that have happened here, but also his unforgettable memory.


    When she came to the wine cellar specially built for Mo Qingyan, her treasures were still stored here.


    Fortunately, it was not affected by the war, and the nuclear battery installed in the shelter was still working well, and the wine in the wine cellar was still well preserved.


    He picked out a bottle, opened it, found a cup and poured a cup for himself. Chen Xin didn''t clean it up, so he sat on the dusty sofa and tasted it alone.


    This familiar but dusty environment gives Chen Xin a different feeling. It stimulates the alcohol and slightly drunk feeling of taste buds, which makes him relax his body and mind. The whole person leans on the sofa and completely empties his thoughts.


    Perhaps it seems to outsiders that Chen Xin is nervous at the moment. Sitting in a dusty room drinking is something that normal people can''t do.


    But for Chen Xin, this is just a feeling.


    But after sitting for a while, the dust in the room still affected the interest.


    It''s just that Chen Xin doesn''t want to clean up the room. You know, after the last upgrade before he left, the whole shelter has become very large. If you want to clean up here, it''s undoubtedly a very troublesome thing. If you have help, you have to clean it up at least all day.


    And Chen Xin doesn''t live here anymore. Even if the military has returned the scientific research center to him, it is obviously impossible for the research department that has settled in dome new town to move back.


    Chen Xin will not return to live here, so it is unnecessary to clean up here.


    However, people are always emotional. What''s more, for Chen Xin, this shelter has additional significance to him, not just a residence.


    "Maybe we can put some scientific research teams here?" Chen Xin said to himself. After drinking, he was a little irrational, but he didn''t make any nonsense decisions: "The land on the other side of the new town is limited, and I was still reporting to my sister for a new experimental site. Since the military here has not used it, I can let some of them come here, otherwise it would be a waste to put such a large facility."


    The scientific research center is well preserved because it is regarded as the front-line headquarters by the military. It is not like the urban area has been completely destroyed and transformed into a defense line.


    Therefore, it is not a problem to move back a part of the research team that needs a new test site.


    As for the food and housing problems of these people after moving back, they don''t have to worry about it. At the beginning, the scientific research center had all kinds of living facilities.


    Besides, it''s really not good. Doesn''t Chen Xin still have a system? One upgrade can solve all the problems.


    At the thought of this, Chen Xin didn''t know whether it was the effect of alcohol, or in Chen Xin''s opinion, it was really better. He killed the residual wine in the wine glass. He stood up from the sofa, regardless of the dust he was stained with, and snapped his fingers at the air.


    As he snapped his fingers, the long lost green light network lit up again in the shelter. After sweeping the whole shelter in an instant, it spread to the outside scientific research center.

 Chapter 818

    "Don''t you live well in the new town? Ah Xin, why do you want to move back here?" in Chen Xin''s private shelter, Qin LAN is sorting out some clothes and putting them in the wardrobe.


    She didn''t understand what Chen Xin thought. Obviously, she lived well in the dome new town, but suddenly said she wanted to move back to the original shelter.


    Facing Qin Lan''s question, Chen Xin hugged her waist from behind her, held her in his arms and asked, "don''t you like to come back to live? Isn''t it more comfortable here than in the new city?"


    "The conditions here are better, but will we add unnecessary trouble when we come back?" Qin LAN still doesn''t quite understand why Chen Xin came back. After all, everyone has moved to the new town: "Besides, you, me and Qing Yan, we all work in the new town. Your parents also live in the new town. Then you come back to live here now. Don''t you think it''s troublesome?"


    Then Qin LAN patted Chen Xin, holding his arm, and said, "don''t bother me. There are still a lot of clothes to clean up. You don''t help!"


    Looking at Qin LAN, Chen Xin couldn''t help laughing.


    But after laughing, he still explained to Qin LAN: "this is my own place anyway. Since it has been taken back now, it''s impossible to leave it here, isn''t it?"


    Chen Xin''s words changed Qin Lan''s expression a little. In fact, she agreed to come with him for Chen Xin''s reason, but she didn''t quite understand why Chen Xin had to come back here.


    Although it is said that the shelter can''t be left deserted, Qin LAN still feels that Chen Xin doesn''t need to move back. He can leave it to others to take care of. He can come back once in a while. There''s no need to move back at all.


    Noticing the change of expression on Qin Lan''s face, Chen Xin held her shoulder again, smiled at her and said: "The test site of the scientific research department I am in charge of in the new town is not enough. After that, I will reopen the scientific research center here, move some research projects back here and sort them out. I can live here when I work here. Alan, you don''t want to see me sleep in the office after I work hard every day?"


    With that, Chen Xin also showed a flattering expression to Qin LAN.


    Hearing what Chen Xin said, Qin LAN immediately gave him a bad look: "don''t think I don''t know. Your office also has a lounge and a bed to sleep. It seems that he is miserable."


    However, although he said so, Qin LAN no longer opposed Chen Xin''s decision.


    After all, after understanding Chen Xin''s ideas, Qin Lan also understood that Chen Xin did not completely move back to live, but lived here when she needed to work here, which naturally made her less opposed.


    Qin LAN likes this shelter very much. The living facilities here are much more comfortable than those in dome new town. After all, this is a shelter carefully built by Chen Xin, and then it has been expanded and upgraded. If Qin LAN doesn''t think it''s too troublesome to move around, Qin LAN won''t object to coming back to live.


    "Since you''re coming back to live, why don''t you help clean up? Don''t expect me to clean up the room alone!" Qin LAN snorted at him when she saw Chen Xin still standing aside and didn''t reach out to help him clean up.


    Seeing that Qin LAN has no objection, Chen Xin quickly reaches out to help her sort out the clothes she brought back.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    When they finished cleaning the room, Chen Xinjiu cooked a table in his familiar kitchen.


    Because the shelter has not been occupied for a long time, the vegetables and fruits planted in the greenhouse grow very badly. After Chen Xin upgraded the shelter again, he just restored the greenhouse to a normal state. He hasn''t cleaned up these crops that have not been taken care of for a long time. Now he just picked some of them that can still be eaten and made a few dishes for Qin LAN and himself.


    However, although the rice noodles in the warehouse have been put for a long time and have become old, they can at least eat.


    "I haven''t eaten the food you cooked by ah Xin for a long time. Since moving to the new town, either you have to work overtime or you can''t see people abroad. It''s rare for you to cook." Qin LAN eats the food cooked by Chen Xin. Although limited by the materials, the cooking is very ordinary and the taste is average, she still has a feeling of long absence.


    In this regard, Chen Xin just smiled and said to her, "when I get back to clean up the greenhouse, I''ll plant vegetables and fruits here again. I''ll make you what you want to eat."


    Although he didn''t say anything, Chen Xin also knew that he didn''t spend much time with his family in the past two years. He had already decided to spend more time with them in the future.


    In fact, he wants to move back to the shelter. He also has the idea of spending more time with his parents and Qin LAN and Mo Qingyan.


    After all, Qin LAN and Mo Qingyan don''t live with him in the new town. They only come to Chen Xin''s house for dinner or get together when they have time.


    So Chen Xin hopes to restore the shelter here, so that Qin LAN and Mo Qingyan can live with him and have more time with them.


    As for his parents, Chen Xin also consulted his parents, but the two elderly seem unwilling to move again, and they prefer the living environment in the new town. After consideration, Chen Xin chose to respect his parents'' opinions and did not let them move back.


    It is precisely because of this that he will avoid the difficult place to live according to the needs of his work, rather than completely move back.


    As for whether Qin LAN and Mo Qingyan have time to live here with him, it is a good problem to solve. After all, he can transfer Qin LAN and Mo Qingyan to the scientific research center here and let them live here and work nearby.


    However, we need to ask Qin LAN and Mo Qingyan for their opinions. Chen Xin did not directly do so.


    "By the way, can the hot spring bathroom still work? I haven''t been in the hot spring for a long time." after dinner, Qin LAN stretched in her seat and suddenly remembered what she missed most in the shelter.


    When Qin LAN mentioned the hot spring bathroom, Chen Xin smiled: "don''t worry. When I repaired here, I focused on the hot spring. Although it was damaged by the previous war, the hot spring can still be used."


    This is also the part of the adjustment made by Chen Xin when he re upgraded the shelter. The previous underground hot spring water was affected by the water vein excavated by alien organisms and the subsequent nuclear bomb explosion. In fact, it has changed a lot. If Chen Xin hadn''t upgraded it, it would be useless now.


    Hearing that the hot spring bathroom was still available, Qin LAN immediately cheered and ran to the hot spring bathroom: "ah Xin, you washed the bowl, I''ll take a bath first!"

 Chapter 819

    After Chen Xin resumed the operation of the high-speed railway station, it became a very important material channel in the Dongting Lake theater.


    Because the railway station in the urban area was too close to Dongting Lake, it had been designated as a war zone at that time. Although the front was pushed forward and that area was built as a defense line, considering the safety of material transportation, the railway station in the urban area was abandoned, and the high-speed railway station was expanded to meet the needs of material distribution in the war zone.


    The high-speed railway station, which used to have only three platforms, has now been expanded to seven platforms, which can accommodate 12 trains to stop and load and unload goods at the same time. It has played a very important role in the previous war.


    After all, this is the nearest place to Junshan island. In the war, it is also one of the main battlefields of the Dongting Lake theater. It consumes a lot of ammunition and other materials every day, and these materials all depend on this railway station for supply and transportation, which really plays a very important role.


    But now that the war is over, the railway station, which used to be very busy every day, is now so deserted that when Chen novice gets off the scientific research department and enters the station by train, there is only their train on the platform.


    "I didn''t expect that we were so embarrassed when we left, and now we still have a day to come back." sitting in the carriage, through the thick double-layer glass windows, the researcher experienced the scene when we left. Looking at the neat platform outside, he couldn''t help feeling it.


    The fellow who sat next to him was transferred to the research department. He had not experienced the evacuation two years ago. He asked curiously, "is our research center here before?"


    "Yes, our former research center is here. It''s a big place, almost one tenth as big as the dome new city." the researcher introduced the original situation to his peers, and his face was full of pride: "At the beginning, the conditions of our research center were really good. It not only had its own ecological planting greenhouse and small dome, but also had an energy tower specially built for the scientific research center, which was responsible for heating and power supply for the scientific research center.


    In addition, there was a Special Force stationed directly outside the scientific research center, responsible for security issues. At that time, if it was not for the outbreak of alien biological invasion, it would even build a special railway to the scientific research center


    Alas, now, the research center doesn''t even have enough test sites. Several project teams have to use the laboratory in turn! Fortunately, academician Chen took back the original place and we can move back! "


    Hearing what the researcher said, his companion showed a surprised expression on his face.


    Although he knew that the scientific research center led by Chen Xin had a very important position before he was transferred to this department, he didn''t expect that they had such exaggerated treatment two years ago.


    This made him curious and asked: "at the beginning, your treatment was so good. Why are there not enough test sites after you arrived in the new city? Our center should also be very important to the country. Aren''t land ships, mobile bases and Titans all developed by our center?"


    "It''s mainly because academician Chen stayed in Europe for a whole year last year!" speaking of this, the researcher immediately looked melancholy: "because the top person in charge of the Department is not in, our research progress is much slower and there is a large backlog of work. After all, director Tang is only a management post, and she can''t make decisions for academician Chen, so many things are delayed."


    Because Chen Xin went to Europe, Tang Tang Tang was in charge of the management of the research center when he was away, but Tang Tang''s level was not enough after all. Many problems can only be reported to the above, and she can''t interfere with the reply from the above.


    Chen Xin is different. Because his identity is different, many Tang Tang Tang need to negotiate and even quarrel with the superior departments again and again. Chen Xin can directly determine it with his own authority.


    Therefore, this led to the fact that Chen Xin had delayed the expansion of the office of the research center on the side of the new city for a year, which could be decided directly, until the war was over when he came back.


    But now there is no need to consider the expansion, because Chen Xin took back the original research center.


    Because the original research center had no land restrictions, it was built very large, and the facilities were perfect, with enough space to accommodate the people of the whole research department.


    Unlike the dome new town, because the size of the dome itself is limited by the design, it is very crowded after accommodating a large number of people beyond the design. The office location of the research center in the new town is only two buildings that were not originally used for scientific research, and there is not enough space to accommodate everyone.


    This is something that was not considered at the beginning. After all, the dome new town was originally just an ecological city under planning. It was used to test whether the city in the ecological dome mode could operate normally. It was not considered that the people of the whole city would move in later, so that the dome accommodated much more people than the original design.


    However, the country has been in a state of war before, and we all know that it is fighting, so we still have a high degree of tolerance for the crowded environment.


    However, after the war, these problems that had been shelved have been put back on the table and need to be dealt with one by one.


    "Speaking of, we can move back to the original research facilities, but what about so many people in the new town? Did they move out of the city? Now the city has been basically transformed into a defense line, and they have no place to move back?" the group left the high-speed railway station and asked the researcher this question on the way to the research center.


    The researcher didn''t know about this problem. He shook his head and said, "I''m afraid academician Chen can know this kind of thing, but I think he should rebuild the city, or build a new dome here? I remember the original plan was to build a dome urban agglomeration. Unfortunately, the war broke out and the plan was shelved."


    "Dome City Group? Did you have to build many domes?" the companion was immediately attracted by the information revealed by the researcher and asked him curiously.


    The researcher nodded affirmatively and told his peers about the original plan: "the original plan of dome new town was put forward by academician Chen. The plan is to build multiple ecological domes to explore how to build an ecological environment in which human beings and nature live in harmony, so as to conduct relevant research on the ecological recovery of Bluestar after the cold winter recedes in the future.


    At that time, I also participated in this project. Now the new city is only the first dome to be built. According to the plan, three or five more domes should be built around it. Unfortunately, the invasion of alien creatures delayed this matter... "

 Chapter 820

    The project team moved back to the scientific research center is only a small part of the scientific research department in charge of Chen Xin, accounting for about one-third of the current staff of the scientific research department, but they are responsible for many projects, and most of them occupy a large area.


    For example, for the research on laser weapons that have been put into practice by Chen Xin, the project team is studying how to manufacture high-power laser weapons, so as to eliminate the enemy by sweeping on the front battlefield, rather than shooting at him.


    In addition to this project team, other research projects requiring large-scale test sites, such as Titan armor improvement research, research and development of new models of power armor, and electromagnetic weapons research, are among the relocation team this time.


    After all, compared with the office building on the other side of the dome new town, the weapon test site specially built on the side of the scientific research center is more suitable for the research of these weapons projects.


    The site of the research center should have been much more spacious. In addition, after Chen Xin came back, he also made an upgrade in order to reopen it. Undoubtedly, all facilities are more comfortable to use, and all project teams are naturally more willing to study here.


    Although it is not impossible to engage in scientific research because of poor conditions, it is obvious that a good research environment can greatly promote the research progress of the project.


    A place that can flutter open, for the projects that these research groups are currently studying, it not only provides them with a test site, but also allows them to better test their own research.


    To take the simplest example, the project team studying power armor used to have only one research room about the size of school teachers. It is no problem to engage in theoretical research and sample trial production.


    However, once they want to conduct sample testing, they have to apply for an additional experimental site, which is shared by several project teams. Whoever needs it can apply.


    If everyone doesn''t have anything to test, it''s OK. There will be a venue soon. However, if several project teams have to test, they must wait in line, which will affect the research progress.


    Back to the research center, the test site assigned by the project team studying power armor is completely enough for testers to run a 50 meter sprint in power armor, so that they can toss whatever they want.


    Thanks to this, all project teams have dug out the projects that had been shelved because there were not enough test sites. For a moment, new project applications filled Chen Xin''s desk.


    Even Chen Xin himself started a new project after moving back to the scientific research center.


    The new project launched by Chen Xin has little to do with the current battle against alien biological invasion, because the problem he is trying to solve now is how to make land ships break through the atmosphere and develop smaller land ships.


    Or you should change your name, such as spaceship or floating ship.


    The land ship originally developed by Chen Xin mainly travels on land. Only when encountering insurmountable obstacles will the anti gravity device be turned on for floating navigation.


    However, in the actual use, at the beginning, we still followed the operation specifications. The main mobile mode is land travel, and the floating mode is only used when necessary.


    However, with the gradual withdrawal of land-based ships from small ships and Chen Xin''s upgrading and upgrading of land-based ships, the vast majority of land-based ships soon chose the floating mode as the main mode of movement. They would land on the ground only when they arrived at their destination or made a short voyage.


    As a result, land ships have basically become floating ships in the atmosphere, flying in the sky all day.


    Therefore, it is also logical that the Aerospace Department found Chen Xin and asked him whether it could make the land-based ship break through the atmosphere and enter outer space.


    In recent years, China''s space sector has been very low-key, and it can even be said that the sense of existence is quite thin.


    This is mainly due to the limitation of the environment. The space Department itself is far away from the lives of ordinary people. In addition, after the end of the world, the sky is covered by dust. Human beings have lost contact with outer space. At the same time, they are unable to launch spacecraft into space. Space activities are almost completely cut off, and it is not enough for the space Department to fade out of people''s vision.


    However, under the wrong circumstances, Chen Xin reopened the sky with the weather controller, and the space Department has resumed contact with the spacecraft that have been wandering in space for several years, which makes the space Department return to people''s vision again.


    However, it is still limited by the impact of the overall environment. Even Yanguo does not have much resources to invest in the aerospace industry, so that the Aerospace Department has been in a tight situation in recent years.


    However, even so, people in the space sector have not given up the construction and research of the space industry.


    With limited funds, they tried to save money and couldn''t carry out space activities. They focused on the research of the original subject


    Over the past few years, although the space Department has not conducted another space activity, it has still produced a lot of scientific research results.


    Some of these research results have been applied to the military field, such as power armor, exoskeleton and protective clothing. Now for Yanguo people, they are used to equipment in daily life, and many technologies originally used in space suits have been applied.


    In fact, even Chen Xin''s land-based ship uses a lot of technology originally used to build spacecraft.


    Otherwise, a ship, even if Chen Xin can upgrade it into a land ship using the system, will never be so easy to really fly and achieve mass production.


    Now, with the end of the domestic war and the adjustment of national policies, the space Department has received a long-time capital injection. In addition, the sky over Yanguo has been reopened, and the original Jiuquan launch site can be used again. The space activities that the space Department has shelved for a long time have been put on the agenda again.


    However, the Aerospace Department also knows that today, unlike in the past, the country can no longer afford large-scale space activities, and the funds they have received are tight, only enough to launch a medium-sized launch vehicle.


    Under such circumstances, the space Department naturally wants to find cheaper ways to enter space, and it is best to recycle.


    The land-based ship developed by Chen Xin naturally entered the vision of the Aerospace Department.


    In their view, since the land ship can fly, is there the possibility of transforming the land ship into a spaceship and sending it into space?


    The question of the Aerospace Department was put on Chen Xin''s desk, and for Chen Xin, there is naturally no "no" answer.

 Chapter 821

    The appearance of the upgraded Research Center has changed greatly compared with the original one. The dome that originally only covered the main building and the entrance and exit of Chen Xin''s private shelter has been enlarged into a large dome that is slightly smaller than the Dome City, but covers the ecological greenhouse, geothermal energy tower and other supporting facilities around the location of the whole research center.


    Moreover, the original weapon test site has also been upgraded, with larger site and more complete and advanced facilities.


    In addition, Chen Xin also added two sets of 3D printing equipment for the research center. With complete raw materials, these two sets of 3D printing equipment can produce all Yanguo''s active equipment except land aircraft carriers and mobile bases, including small land ships.


    To this end, Chen Xin also specially opened a dock next to the original main building of the research center to park a small land ship produced.


    Naturally, this small land-based ship is an experimental object made by Chen Xin to answer the question of the space Department.


    However, the size of this land ship is very small. Strictly speaking, it can only be regarded as a miniature land ship, because it is only half the size of the escort land ship, which is almost as large as the mining land ship rented by the state to those mining miners, or even smaller.


    The land ship is so small that it can naturally accommodate a lot less personnel. Under Chen Xin''s repeated simplification, the load of the land ship is 12-15 people.


    There are only ten narrow cabins on board. Of course, compared with the situation that astronauts can only sit in the spacecraft and have trouble turning around in the past, it is still much more generous. At least there are two bunks and a table in the cabin, which is the size of a normal room.


    Although there are ten compartments, under normal circumstances, two compartments will be used to store materials to improve the activity time of the land ship.


    The whole ship is driven by nuclear power, and it is not a nuclear battery, but a miniature nuclear reactor used on a nuclear powered train.


    This undoubtedly provides sufficient power for the special small land ship, so that it can use plasma thrusters to send itself out of the atmosphere and into space.


    The reason why plasma thrusters are used is mainly because the core component used for the floating of land-based ships is the anti gravity generator. This equipment can counteract the influence of gravity on land-based ships, but what it can do is counteract each other with gravity and can not produce additional lift.


    At the altitude still affected by gravity, the anti gravity generator can effectively offset the influence of gravity and allow the land ship to adjust the flight altitude at will.


    However, if the height of the land ship continues to increase, the lift provided by the anti gravity generator will be smaller and smaller until it reaches the lifting limit of the land ship.


    Although this ceiling is close to breaking through the atmosphere into space in a sense, the small land ship can''t break through the atmosphere without the help of additional lift.


    It is for this reason that Chen Xincai installed a high-power plasma propeller to provide enough thrust to send the land ship into space.


    If you want to go into space, thrust alone is not enough. After all, there is a vacuum in space. Land ships must ensure that the hull is completely sealed. Otherwise, if there is air leakage and precious air is lost, the air leakage point will become an additional force application point, making the hull out of control.


    This is one of the reasons why so far, the spacecraft built by humans are not large, because it is necessary to ensure the tightness of the spacecraft and make the spacecraft shell enough to cope with the harsh environment of outer space, which is an extremely severe test for both materials and structure.


    Although Chen Xin can upgrade the whole land ship into a spaceship capable of interstellar navigation by means of system upgrading, considering that it is a spacecraft to be delivered to the space Department, Chen Xin still uses the technology that Yanguo has and can do to build the land ship as much as possible.


    Fortunately, there is now 3D printing technology, which can directly print the shell of the whole ship without any gap. Compared with the traditional production and construction technology, it is undoubtedly much better in ensuring the tightness of the hull.


    As for the hull materials of the land ship, Chen Xin doesn''t have to worry about it. The Aerospace Department has come up with the best material formula in their hands, which was previously used in spacecraft manufacturing.


    However, even before the disaster, the price of these materials was so expensive that it was amazing. Even the dishes of the top countries of Bluestar could afford it. As for now after the end of the world, even the best country with the current comprehensive national strength recovery could not be taken out so easily.


    Of course, countries with reserves of raw materials are not without them, but these raw materials themselves are scarce resources. In addition to the aerospace sector, there is also a great demand in other departments and fields.


    Far from it, just the reactor for producing nuclear powered locomotives also needs to use a large number of scarce resources to ensure the safety of nuclear reactors.


    This is one of the main reasons why Chen Xin built the land ship so small, because the raw materials are really not enough.


    The raw materials granted by the state to the Aerospace Department, together with some of the materials they still have on hand, can only build such a large land ship after Chen Xin improves the utilization rate of materials as much as possible.


    Of course, even so, the length of this land-based ship is more than 50 meters long. It really belongs to the category of giants in spacecraft.


    For such a large ship, except for the multi-layer shell with sufficient thickness to ensure the strength of the hull, it is naturally impossible to have only the crew cabin inside the hull.


    In addition to the standard configuration of the bridge''s cockpit, power cabin and anti gravity generator, Chen Xin also prepared a "large" comprehensive laboratory for spacecraft and an ecological greenhouse.


    The role of comprehensive laboratory is needless to say. One of the most important purposes of aerospace activities is to carry out various scientific experiments in space. A large comprehensive laboratory is very valuable for aerospace activities.


    Before the disaster, countries built space stations to a large extent in order to have enough space in space for scientific experiments.


    As for the ecological greenhouse, on the one hand, it is also used for biological research as part of space experiments, on the other hand, it is used to produce food to meet the consumption of the ship.


    After all, even if the cost is reduced, every gram of load in space is still very valuable. It is certainly the best to make food self-sufficient and free more space to carry other materials.


    On the premise of meeting these conditions, the land ship came into being and was built by Chen Xin.

 Chapter 822

    The newly built land ship... No, it should be said that the ship needs to be actually tested to find out whether there are any problems or what needs to be improved.


    To test the spacecraft, it was not the crew of the Navy or land ship, but the astronauts sent by the space Department.


    These astronauts were reconvened by the space department after Chen Xin created a super storm to purify the sky of Yanguo, and after a period of recovery training.


    Originally, the plan of the space Department was to send them to heaven to restore the use of the space station. However, there has been a lack of sufficient funds to restart space activities. As a result, this plan has not been carried out, and the astronauts can only continue to maintain training and have no chance to go to heaven again.


    But now with the spaceship built by Chen Xin, they finally have a chance to go back to heaven and let mankind return to the universe.


    Moreover, the spaceship Chen Xin built this time has enough space to accommodate more than a dozen people, which is more capable of loading than the space shuttle built by the Federation and suvia, and the number of astronauts who can go to heaven has reached an unprecedented 12, which is unprecedented in history.


    Of course, it is not a simple thing for the 12 astronauts to go to heaven. Even if they have a spacecraft that can send them to heaven, they also need to be familiar with the operation process of the spacecraft and consider going to heaven after completing the test process of the spacecraft.


    Therefore, the test of the spacecraft is not only for the spacecraft itself, but also for these astronauts.


    Among these astronauts, Chen Xin also met Zhang Chengguang and others who were saved by him in those years. When he saw acquaintances for a long time, both Chen Xin and Zhang Chengguang were quite impressed.


    In those days, Zhang Chengguang and his three men were determined to die to prevent the impact of meteorites. After the mission failed, they stayed in the space station. Finally, there was no way, so they fought hard and forced to land back to Bluestar.


    If they hadn''t met Chen Xin in the wild, they might not have survived.


    This also led to Zhang Chengguang''s great gratitude to Chen Xin and always remember this kindness.


    Originally, they intended to repay Chen Xin for his care, but they didn''t expect that Chen Xin would soar like a rocket and soon reach a height they could only look up to.


    Now when we meet again, they are still astronauts, but Chen Xin is already an important scientist who plays an important role in the country. They have to sigh that things are changeable.


    Although Chen Xin has some feelings about this, he doesn''t care too much about it.


    Saving the three astronauts was just easy for him, not much to care about.


    Although saving three astronauts would have had a great impact on his life if he had no system, he had a system after all, and his life situation was completely different after that time.


    He handed over with the astronauts and specifically taught them how to drive the spacecraft. Of course, Chen Xin doesn''t need to come in person. His own staff is responsible for this matter. He only needs to overview the project, deal with some possible problems, and make subsequent improvements to the spacecraft.


    After the handover, the ownership of the spacecraft was transferred from the scientific research center to the Aerospace Department, but the spacecraft will continue to stay at the scientific research center until all tests are completed, and the astronauts will drive back to the launch site in Jiuquan to prepare for future space travel.


    The whole test process will last for a long time, and the space Department will also carry out various experiments before going to space. Therefore, the 12 astronauts and the team of the space Department accompanying them will stay in the scientific research center for a long time.


    So after handling the handover of the spacecraft, Chen Xin went to busy with other things.


    There are not many things in the scientific research center. In order to maintain management, Tang Tang stayed in the dome new city to be responsible for administration. Many things handled by Tang Tang Tang in the scientific research center were put in front of Chen Xin, but these things are only cumbersome and not troublesome.


    However, even so, Chen Xin wrote himself an intelligent program to classify and preprocess all the things that need him to deal with. Except for the more important things that need his manual approval, other trivial matters are handed over to the intelligent program.


    After running like this for a week or two, seeing that there was no problem, Chen Xin suddenly had a new idea in his mind.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    At the beginning of the establishment of the scientific research center, it was equipped with a supercomputer.


    The main purpose of this computer was to give various scientific research groups at that time to calculate and meet the research needs. Of course, at that time, the scientific research center could also obtain a supercomputer under the condition of national resource shortage. The high-level mainly attached importance to Chen Xin.


    Facts have proved that there is no mistake in the high-level emphasis, and Chen Xin has indeed made a considerable contribution to the country.


    But the use of supercomputers is not much, because Chen Xin is a guy who depends on the system, not orthodox scientific research.


    Therefore, the supercomputers are mostly used by Chen novice in various research groups, but he doesn''t use them very much himself.


    However, later, Chen Xin made use of supercomputers and combined them with virtual technology to create a virtual illusion, which can simulate and calculate various projects. On the contrary, it is more useful than using supercomputers alone.


    Of course, Chen Xin''s usage also consumes more computing power on the supercomputer itself, so that at that time, he also upgraded the supercomputer itself so that it can afford this consumption.


    However, at the time of evacuation, Chen Xin had to leave the supercomputer because it was inconvenient to carry.


    After the military took over, it has been using this supercomputer and virtual technology to calculate and simulate the battlefield situation, which has made a contribution to the war.


    Now, for this supercomputer, Chen Xin is ready to upgrade again and install the intelligent program he wrote on this supercomputer.


    This was not a zero hour idea. Before the invasion of alien organisms, the scientific research center was carrying out research on artificial intelligence, but the invasion of alien organisms interrupted the research progress at that time.


    After that, the scientific research center moved to the dome new city. Due to the limited conditions in all aspects, the research of artificial intelligence has been greatly affected, and no achievements have been made in recent years.


    This time, Chen Xin wants to really create a real sense of artificial intelligence.


    To this end, he specially transferred his white dragon to the scientific research center, and planned to use little white dragon as a template to write her program for manufacturing artificial intelligence.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 823

    While Chen Xin was busy manufacturing artificial intelligence, the scientific research department of dome new town received instructions from their superiors to restart the construction plan of Dome City.


    The construction plan of the dome city is an important project related to the national economy and people''s livelihood and the future reconstruction of the blue star ecological environment before the invasion of alien organisms.


    Therefore, when the country had just recovered from the plight after the disaster, it still invested a lot of resources to build the dome new city, and planned to invest enough scientific research in it to study the coexistence and development of ecosystem and human beings.


    According to the original plan, after the dome new town is completed, the state will build more ecological domes in three to five years to expand the dome new town into a city group.


    However, with the invasion of alien creatures, the construction of the new dome was cancelled, and the whole plan was shelved. All kinds of resources were sent to the front line against alien creatures. The Dome City, which costs a lot and is not helpful to the war, will naturally be suspended.


    The only finished product of the whole dome urban construction plan has also become a resettlement site, which has resettled the population far beyond the design bearing limit.


    Now, with the end of the civil war and the restart of various construction projects, this large-scale construction project that was stopped before has naturally been restarted under the promotion of some people.


    However, the construction of the Dome City costs a lot. Even if the high-rise wants to restart the construction of the Dome City, it will not start construction immediately in the short term.


    In particular, the project has been stopped for several years. Although the original drawings are still there, it also needs time to sort them out.


    You know, even the drawings of an aircraft can be filled with a container, not to mention the drawings of a city?


    Even if these drawings have been paperless, they are still very large data and need time to rearrange them.


    Especially for the problems encountered in the construction of dome new town, the modifications made on the drawings used in the construction should also be fed back to the original drawings.


    This is undoubtedly a huge project, which requires a lot of manpower to do these things.


    And these people have to be professionals. Most people can''t deal with these architectural drawings.


    Therefore, several design institutes and their subordinate design institutes that still exist in China have been transferred, and a large number of professionals have been concentrated in the scientific research center, and some have carried out surveying and mapping in the dome new town.


    Surveying and mapping the dome new city is naturally due. When the new city was built, it was not designed to accommodate more than 100000 people, and the space in the city is not allowed.


    But what happened later, the city was crammed with more than 100000 people, which undoubtedly made the original architectural planning of the city a mess, and many original designs were modified.


    Re mapping, in order to compare the current dome new town with the original drawings.


    As for why we should go to the scientific research center, this is naturally the reason why the electronic version of the design drawings of dome new town is stored in the supercomputer of the scientific research center.


    Moreover, the scientific research center is large and has a virtual illusion. You can directly simulate the drawings and calculate the differences through the supercomputer. Isn''t it easier than comparing yourself with the vast sea of drawings and data?


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Chen Xin was surprised that the state would restart the construction of the dome city.


    In his capacity, he can naturally get access to more information that other people can''t get access to. Through this information, Chen Xin can clearly understand that the current situation of the country is not as good as expected.


    Despite the end of the domestic war, the country has shifted its focus back to domestic construction, but now it has to support the European battlefield on the one hand and build a new defense line in the Middle East on the other hand. It can be said that the domestic resource consumption is still very large.


    Despite the European supplement and the considerable output provided by the domestic small individual contracted mines, the current domestic life still needs to be calculated.


    At this time, Chen Xin did not agree to restart the large-scale construction project of Dome City.


    In particular, the original design intention of the dome city was to establish an ecological city rather than a residential city, which is very different.


    He doesn''t think the country now has enough resources and energy to restart the original research project of ecosystem restoration.


    Not that this project is unimportant, but because the most important thing now is not this, and a lot of resources should not be used on this.


    However, although he did not agree with the high-level practice, Chen Xin did not interfere, but asked the high-level about it through his own authority.


    In fact, it''s strange that Chen Xin didn''t know about it in advance.


    As Chen Xin, if the state wants to restart the construction project of Dome City, he should know in advance.


    In particular, he was responsible for the Dome City Project at the beginning, and now he has the most say in the dome new town. It is a very abnormal thing that the project is restarted without him.


    However, when Chen Xin asked the senior management about this matter, the senior management replied that the dome city plan was not prepared for domestic construction, but intended to be used in the Middle East.


    This really surprised Chen Xin, even more than the high-level directly bypassed him and confirmed it.


    Although it is said that the construction of the dome city consumes resources, it is not a problem to build two new domes if it is crowded. It is just why the new dome will be built in the Middle East rather than in China?


    This is a bit unreasonable.


    The explanation given by the high level is that the high level responsible for the construction of the Middle East defense line feels that it is very dangerous for the population of the Middle East to be concentrated on the Mesopotamian plain. If alien creatures invade the Middle East, the residents of this region will suffer huge losses.


    Therefore, the high-level plan is to move the population of the Middle East to the Iranian Plateau and let them move behind the Middle East defense line, so that they will not suffer huge losses even if alien creatures invade.


    Of course, there is no problem with this scheme, but the Iranian plateau is mainly plain terrain. If it is used to build shelters, it is obvious that underground buildings are not suitable. At this time, Dome City, a large shelter building suitable for construction in plain areas, has naturally become the first choice for this high-rise.


    It is precisely because of this idea that the senior manager restarted the Dome City project with his own authority and asked the domestic government to sort out the drawings.


    It is precisely because of this idea that the senior manager restarted the Dome City project with his own authority and asked the domestic government to sort out the drawings.

 Chapter 824

    Is it necessary to build a dome city in the Middle East?


    If only from the perspective of demand, it is still necessary.


    After all, the original cities on the Iranian plateau were abandoned at this time. If you want to resettle a large number of people, a city is necessary.


    Even because there are nearly ten million people in the Middle East at this time, one city is far from enough.


    But in terms of cost performance, building a dome city in the Middle East is not so necessary, or even a waste.


    Compared with building a dome City, the cost of building ordinary shelters and all supporting facilities to accommodate the same population is less than one-third of the cost of building a dome city.


    In fact, a more economical and practical way is to build temporary camps with movable plank houses and functional shelters to resettle a large number of people, and then let these people build the temporary camps into permanent cities by themselves.


    This is not only convenient and fast, but also a large number of people can be resettled, and the cost is more economical.


    Compared with the Dome City, the cost of accommodating one million people with movable plank houses and functional shelters is equivalent to that of building a dome city that can accommodate 100000 people.


    Obviously, if the country really wants to resettle the population in the Middle East, this is the most appropriate approach, especially when these people are used to build the Middle East defense line. A temporary camp that can be moved at any time is simply not suitable for these Middle East people.


    Even if Chen Xin is willing, he can integrate a set of cheaper and practical simple camps, which can not only meet the use needs, but also quickly build them to accommodate a large number of people.


    Chen Xin didn''t believe that the high-level leader who presided over the construction of the defense line in the Middle East didn''t understand these things, but the other party still sent the requirements for the Dome City drawings, which inevitably made Chen Xin feel very confused and puzzled.


    With an attitude of being responsible for things, Chen Xin sent an inquiry message to the senior manager.


    The high-level in the Middle East gave Chen Xin face and soon sent a reply.


    Chen Xin carefully read the reply given by the senior, and finally figured out what was going on.


    In fact, there were some misunderstandings, and the senior''s meaning was misconveyed.


    First of all, the state does have the intention to restart the construction of the Dome City, but it has not determined it. After receiving the request of the middle and upper classes in the Middle East, the high-level person in charge of the construction of the defense line in the Middle East thought of the Dome City, so he planned to build such a city for the Middle East upper classes who asked for it in the Middle East.


    However, it is obvious that this city cannot be funded by Yanguo. After all, our domestic resources are tight now. How can we have the resources to build a dome city for the foreign upper class to enjoy?


    But the upper class of these Middle Easterners controls the official institutions in the Middle East. If their requirements are not met, it will affect the construction of the Middle East defense line.


    Therefore, this high-level official asked for the drawings from China and planned to modify them and throw them to the upper classes in the Middle East. If they were willing to pay for materials, Yanguo could build such a city for them to live in.


    However, if these Middle Easterners intend to whore for nothing, the country will have "temporary" economic difficulties. Everything will be based on the construction of the defense line, and then "discuss" the construction of the Dome City after the defense line is repaired.


    This is one of the reasons why Chen Xin, the head of the Dome City project, did not know that the Dome City project was restarted, because the state did not plan to build the dome city immediately, and naturally did not inform Chen Xin.


    In fact, it can''t be completely said that there was No. the senior management issued instructions to the scientific research department of dome new town, but Chen Xin was not notified separately. In addition, he was not in dome new town at this time, so things missed.


    After all, the scientific research center has just resumed operation, and the communication with dome new town is not smooth. It is not difficult to understand the interpretation errors.


    After clarifying the situation, Chen Xin naturally responded to the high-level request.


    Through the artificial intelligence installed on the upgraded supercomputer, Chen Xin quickly sorted out the drawings of the Dome City and "optimized" it.


    The initial design policy of Dome City is ecological city, so the design of the city will accommodate 60000 people, and a complete urban ecosystem will be retained.


    This was a satisfactory design for Yanguo at that time, and Yanguo could afford to build such a pilot city at that time.


    But for the Middle East, such a design, although there is no problem, is not practical.


    After all, at that time, Yanguo wanted to maintain an ecosystem in the Dome City in order to study the reconstruction of the blue star ecological environment after the disaster. For the upper classes in the Middle East, this was unnecessary and they couldn''t afford to play.


    In addition, considering the need to accommodate a large population, Chen Xin "optimized" the Dome City, which is a very logical thing.


    After Chen Xin''s adjustment, the number of people that can be accommodated in the Dome City has been greatly improved, from 60000 to 120000. The original ecosystem inside the city has been deleted by him, and only some self-sustaining green belts have been retained.


    Chen Xin did not make major changes to the overall planning structure of the city, but adjusted the layout according to the appearance of the dome new town, so that the land vacated after deleting the ecosystem can be fully utilized.


    Chen Xin also showed the adjusted drawing to professional architects. They only proposed some detailed modifications and had no comments on the drawing itself.


    Therefore, after the drawing was determined, the drawing was sent to the high-rise in the Middle East, and Chen Xin also attached a city projection video simulated by the virtual fantasy as display materials.


    The senior management who got this drawing and demonstration video was naturally very satisfied with it and sent the video and drawings to the official institutions in the Middle East.


    The official agencies in the Middle East were also quite satisfied with the drawing. Those upper classes even immediately asked Yanguo to help them build such a city. As for Yanguo''s requirements, they also instructed the official agencies to agree.


    After receiving such a response from the official institutions of the Middle East, it is obvious that the high-level official did not intend to be polite. While the Middle East mobilized labor to build the defense line, he also wanted to empty the whole Middle East and put forward resource requirements for them.


    The Middle East understood the current situation and happily provided the high-level with a lot of resources and labor to start building the Aleppo defense line and the Middle East defense line itself.

 Chapter 825

    After the construction of the defense line in the Middle East began to go smoothly, Chen Xin had some ideas about the dome urban design map that was turned out and rearranged.


    The state wants to restart the construction of the dome city. He has confirmed this intention to the high-rise. The high-rise does have this idea, but the high-rise wants to adjust the original design scheme of the dome city.


    As has been said before, this design scheme was originally experimental in nature. The purpose is to study the coexistence between human beings and the ecological environment and the restoration of the ecological environment after a disaster.


    According to the original design, after the dome city is built, it will not be finished. A large number of scientific research institutions and staff will maintain it, cultivate and reproduce species in it, so as to establish the ecosystem designed by Chen Xin, so that it can maintain its self circulation and stability.


    In general, this is not so much a city as a large research facility.


    For today''s Yanguo, the restart of the construction of the dome city is obviously not to continue the research project, but to accommodate the people.


    Since the sky was purified and the sun rose again, the country has been planning to bring people living underground back to the ground.


    After all, as we all know, people need to bask in the sun. Living underground for a long time will have various negative effects on their bodies. There is no way to live in underground shelters, but if the situation improves, people should return to the ground to live again.


    In fact, after the sun came out again, people in some areas and cities began to transform their shelters and prepare to return to the ground.


    If it had not been delayed by the war with alien creatures, the country would have wanted to start promoting this aspect.


    Restarting the construction of the dome city is an attempt to this end.


    After all, life in the dome city is basically no different from that in the city before the disaster, except that there is a cover on the top of the head.


    Therefore, it is now necessary to adjust the functions of the Dome City from an experimental scientific research city to a more professional living city.


    In fact, it is not difficult to do this. Today''s dome new city is such a city. The dome new city, which accommodates more than 100000 immigrants, is now an out and out living city, but in some aspects, it is different from a simple living city because of the limitations of the original urban design and the needs of supporting war.


    Chen Xin''s drawings after "optimization" again are very appropriate.


    After all, this is a city designed simply to accommodate the population and meet the needs of life.


    This drawing was not only sent to the senior level responsible for repairing the defense line in the Middle East, but also received by the senior level in China.


    However, the cost of Dome City is still too high. Even if China can afford to build a new dome, it is still a heavy burden.


    Therefore, the senior management expressed to Chen Xin whether the cost can be reduced, hoping that he can optimize the drawings again, so that the country can at least afford to build two dome cities at the same time.


    Facing the request put forward by the high level, Chen Xin did not refuse, but it was not easy to realize.


    To reduce the construction cost, in addition to reducing the material input, it is to reduce the labor cost. After all, the construction cost is mainly these, and the land does not need to be included in the cost now. The land belongs to the state and does not need to be counted as money.


    However, both materials and labor are not good for compression.


    In terms of labor cost, there is no room for compression, unless we can improve the current construction mode on a large scale and complete more work with fewer workers, which can reduce the cost.


    But this is not an easy thing to do, and even if the labor cost is reduced, it will certainly not meet the requirements that the high-level hope that the country can afford the construction of two dome cities at the same time.


    After all, the labor cost does not account for the majority for the Dome City, and the greater cost is actually in the materials for building the dome.


    When designing the supporting structure of the dome, Chen Xin deliberately chose light materials, and even the outer layer of the dome was made of EFTE airbag and light thermal insulation materials instead of heavy materials such as glass.


    These lightweight materials greatly reduced the self weight of the dome itself, while maintaining sufficient structural strength. In addition, some designs added by Chen later, there was the large dome of the dome new city, which sheltered more than 100000 people in the whole city.


    However, the use of these materials is also the largest part of the construction cost of the dome city.


    Even before the disaster, these materials themselves were relatively high-cost materials, but at that time, there was enough industrial scale to produce in mass, which could naturally suppress the cost to an acceptable level.


    However, the industrial scale is obviously not as large as that before the disaster, and the domestic industrial production capacity also supports Europe and the Middle East. There are not many resources that can be squeezed out.


    If we can not reduce the cost, with the current affordability of the country, we can only afford the construction of a dome City, and even some are tight.


    However, if these materials are replaced with cheaper materials, it will affect the weight and structure of the dome. If you want to do so, you must overturn the original design, which is tantamount to pushing everything down and starting over.


    Even for Chen Xin, this is not an easy thing to accomplish.


    However, he convened relevant researchers to study this issue and see how to meet the requirements put forward by the high-level.


    The first issue raised is the construction. Some people think that the current 3D printing technology can be used for the construction of dome cities. After all, this printing technology is convenient and can save labor investment.


    Chen Xin quickly adopted this suggestion and designed a new 3D printing equipment that can be used for dome construction. As long as the materials are complete, the supporting structure of the dome can be printed directly.


    But this is not enough. Although this has effectively reduced some construction costs, it still can not meet the standards required by the high-level.


    If you want to really reduce the cost, you still have to make an article on the materials.


    In the face of this problem, these researchers convened by Chen Xin put forward two diametrically opposite schemes.


    One party hopes to develop new materials. As long as it can develop materials that also meet the construction requirements and have low cost, it can meet the requirements of the high-level.


    On the other hand, we hope to work hard on the structure. By optimizing the structure and replacing the originally expensive materials with cheap materials, we can also meet the requirements of high-rise buildings.

 Chapter 826

    How to reduce the material cost of the dome has become the biggest headache for Chen Xin and the whole design team.


    The original structure of the dome was mainly composed of high-performance light steel as the main structural support, EFTE airbag and support structure, and the outer layer was covered with thermal insulation materials.


    Obviously, there is nothing to adjust and modify the outer thermal insulation layer and EFTE airbag. When Chen Xin first designed the dome, he has done enough optimization for these two layers, and the structure and materials are the optimal solution.


    So it''s the same sentence. Unless you change the materials, there''s nothing to adjust.


    Changing materials... Not to mention how troublesome the research and development of a new material is, even if Chen Xin can produce a new material through the system, there is still a long distance between the invention of a material in the laboratory and large-scale industrial production.


    We should study the production process, develop production equipment, establish factories and formulate process flow


    It can be said that a new material can be turned from a laboratory into an industrial product that can be mass produced in three to five years or more.


    This is why Chen Xin did not upgrade the dome materials through the system.


    Replacing a new material can indeed meet all requirements, but corresponding to it, a new set of new material production line needs to be established.


    Even if Chen Xin transforms the old production line into a production line of new materials by means of system upgrading, it is still not a small project. After all, Chen Xin can only solve the problems of production equipment, such as production process, process flow and process parameters. He has no way to solve them and still depends on other researchers to explore.


    Although the problem of production equipment is the most troublesome and difficult problem in the application of new materials.


    Therefore, although the development of a new material can solve all problems and meet the requirements put forward by the senior management, Chen Xinhe and the whole design team only take this scheme as an alternative. In addition to allowing researchers to speed up the research progress in this field, they still put more hope on how to replace high-performance light steel with existing cheap materials.


    "The steel we use now is a special light material. If ordinary steel or light aluminum is used, the cost is only one third of that of this material, which can be said to be the best solution at present." in the conference room, a researcher is saying: "However, if ordinary steel is used, even if the dome is built according to the existing structure, the self weight of the dome will be increased by at least four times. Light aluminum can reduce this proportion to twice, but it still exceeds the safe bearing range of the supporting structure of the dome in the original design scheme."


    Using ordinary steel or light aluminum can effectively reduce the cost, but because the weight of ordinary steel and light aluminum is still heavier than the original high-performance light steel, the weight of the dome will increase a lot.


    It''s not that the supporting structure can''t bear it, but the heavy weight undoubtedly increases the risk of dome collapse.


    After all, this is a large dome shrouded in a city. All the weight is borne by the supporting structure itself. If the weight is too heavy, it will undoubtedly cause a great burden on the whole structure.


    "What about strengthening the supporting structure?" someone suggested.


    "Not very good. Strengthening the supporting structure also means increasing the weight. It''s better to add supporting columns." someone on one side denied the proposal.


    "It''s feasible to add supporting columns, but in that case, we have to build tall buildings in the city and put the supporting points on the roof." a designer pressed twice on the table and projected the design drawing and three-dimensional projection of the dome in front of the people. He adjusted the design drawing, showed the columns on it, and then continued: "In this way, the structure and strength of the dome can be guaranteed, but these high-rise buildings as support points have become a problem."


    The designer didn''t say what the problem was, but everyone participating in the meeting understood what he meant, because if a tall building wants to be high, it can''t be too heavy.


    But this contradicts the load-bearing. After all, these high-rise buildings should be used as the supporting columns of the whole dome. If they can''t bear the load, it''s meaningless.


    "How many solid cement columns?" some people obviously don''t give up on this. Since it''s impossible to build a high-rise building, they just pour several solid reinforced concrete support columns. If they don''t believe it, they can''t support it.


    "In that case, reducing the cost is meaningless." the designer calculated the project cost and showed it, which immediately made everyone at the meeting shake their heads.


    Pouring reinforced concrete pillars is not just using steel bars to build shelves, and then pouring cement into them. If you want to build a reinforced concrete pillar as big as a tall building, it will not be cheaper than building several tall buildings.


    Faced with such a result, everyone was silent for a moment.


    Obviously, although the solutions they can come up with now are not without solutions that can solve the problem, none of these solutions have shortcomings.


    It seems impossible to find a perfect solution to the problem and meet all the requirements at the same time.


    Just when people were thinking about whether they were using alternative schemes and replacing new high-strength steel with new materials, some people tentatively said, "do you want to use foam metal?"


    "Bubble metal? Is it not strong enough?" people questioned about what foam metals are.


    The so-called foam metal is a kind of material obtained through special processing, so that metallic materials contain foam pores.


    This material is one of the new materials before the disaster. It has good air permeability and small density, and has certain strength, ductility and additivity. It can be used as lightweight structural materials.


    This material has been used in the core of aircraft clamping devices for a long time. In the aerospace and missile industries, foam metal is used as a lightweight and heat transfer supporting structure.


    Because it can be welded, glued or electroplated to the structure, it can also be made into sandwich bearing members.


    "It sounds feasible. Is there any information on this?" hearing this suggestion, Chen Xin thought it seemed feasible, but he didn''t understand this material.


    The people who put forward the proposal quickly adjusted the foam metal related data and sent them to everyone.


    Looking at the materials related to foam metal materials projected in front of him, Chen Xin felt that this material seemed to meet their needs.


    Then he thought, "it seems that foam metals can be considered, so we can assess the feasibility of this material. If we can use it, we should come up with a plan as soon as possible."

 Chapter 827

    Now that the direction has been determined, the results will naturally be obtained soon.


    Soon a report was put in front of Chen Xin.


    Foam metal is indeed a very good material, with a certain degree of strength and ductility, and the foam structure can make it absorb energy from the impact just like ordinary foam material, and its application prospect is very extensive.


    However, in construction, this material is more used in laminated composites and will not be used alone.


    After all, even if the strength of the foam metal is not bad, but a foam metal and a solid metal ingot, the two can withstand the static is obviously larger.


    Foam metal can not be used as a support, such as aircraft fuselage and offshore platform, thin walled cylindrical shells are easily damaged under load. But if the shell is supported by continuous foam metal coils, the structure has greater strength than the unreinforced center shell with the same diameter and size.


    However, it is a special application environment, which is different from the requirements of high-strength and light materials required for dome support structures.


    But Chen Xin did not mind. The strength of foam metal material is not enough to be used as the main material, which does not mean that this material can not be used.


    Because foam metal material itself is not used as a separate material.


    "Filling with foam metal materials, and then using other high strength materials as skeletons, can produce supporting structures that meet the requirements of dome structure and reduce costs at the same time?" Chen Xin elaborated his ideas and asked others.


    "Theoretically, it should be possible, but whether it can be done or not needs to be tested, and the specific material selected should also be tested." a researcher in materials science replied to Chen Xin''s query.


    Hearing this answer, Chen Xin nodded and said, "let''s do it. It''s time to do experiments, tests, tests, and give me a result as soon as possible."


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Although Chen Xin did not provide additional help in this matter, the researchers themselves quickly came up with a feasible scheme.


    "After testing, we determined that using high strength material as skeleton and filling with foam metal material can really replace the original high-strength steel. Although the total weight of the dome is still 30%, the strength and weight can meet the design requirements." a researcher submitted their test report to Chen Xin.


    After Chen Xin upgraded the supercomputer of the scientific research center, everyone in the whole scientific research center now doesn''t use paper much, but uses tablet computers for direct file transmission, which also makes the whole scientific research center look full of science fiction.


    Chen Xin quickly browsed the report submitted by the other party, turned to the final result, took a serious look, and then asked, "the total weight of the dome has increased by 30% compared with the original, which can meet the design requirements? Have you confirmed with the design department?"


    "It has been confirmed. The result given by the design department is that with our current scheme, the safety range of the total weight of the dome is 45% more than the original weight. If the key parts are reinforced and the structure is optimized, this value can be enlarged to 60%. With our current scheme, the requirements can be met." the researcher replied to Chen Xin, There was an uncontrollable excitement on his face.


    "What about the cost?" the new scheme can meet the requirements in terms of structural strength and weight. Chen Xin is not surprised. He is more concerned about the cost.


    The researchers clearly understand that the cost problem is the main reason why they came up with this scheme, so they replied: "the cost of our scheme is about 60% lower than the original design, which can fully meet the above requirements of bearing the construction of two dome cities at the same time."


    Hearing what the researchers said, Chen Xin nodded with satisfaction and said to him, "in that case, submit this report to the design department and modify the design drawings according to this scheme. I hope to see the modified design drawings as soon as possible."


    "Yes, academician, we will finish it as soon as possible." the researcher nodded and left Chen Xin''s office.


    After the researchers left, Chen Xin leaned back on his chair and breathed a sigh.


    Reach out and click twice on the desktop of the desk, call out the design drawing of the Dome City and project it. Chen Xin said to himself: "since the construction cost of the dome city is no longer a problem, it is entirely possible to build the urban agglomeration according to my previous idea.


    A dome is an urban area. When multiple domes are connected, it is a ''big city''.


    Well... It seems that there is no need for multiple domes, one large dome and several small domes. Together, they are also a city. The large dome can be used as the main functional area and the small dome as the residential area... "


    Chen Xin was talking to himself, and the projection on the table was changing with his ideas.


    "Academician, in terms of urban planning and construction costs, a large dome and several small domes attached to the large dome are a more appropriate scheme." a voice sounded in the office, and a blue female face appeared on Chen Xin''s desk.


    This is the artificial intelligence installed by Chen Xin after upgrading the supercomputer of the scientific research center. In addition to providing computational support to all research departments and researchers of the scientific research center, she is also the housekeeper of the scientific research center.


    Through the cameras and other electronic devices installed in the scientific research center, it can be said that the whole scientific research center is under her control, while Chen Xin shares part of her control authority with the artificial intelligence, so that she can handle all the affairs of the scientific research center according to the preset rules.


    It can be said that in addition to the things that Chen Xin must personally confirm and deal with, the large and small things of the scientific research center are now handled by this artificial intelligence. She is equivalent to the role of Tang Tang Tang, but compared with Tang Tang Tang, the efficiency and trivial degree of artificial intelligence in dealing with things are much better.


    Of course, artificial intelligence will be a little rigid in dealing with things. It will only be carried out in strict accordance with preset programs and rules. It is not as flexible as human beings.


    As for why she made suggestions to Chen Xin, Chen Xin opened her auxiliary function and asked her to calculate the cost performance of her ideas.


    "Xiyao, calculate whether the structure can support if the dome is built according to this structure." Chen Xin adjusted the projection on the table and issued a new instruction to artificial intelligence.


    "Yes, academician." after accepting Chen Xin''s instruction, Xiyao began a new calculus.

 Chapter 828

    The design of the dome city was soon finalized.


    Foam metal is used extensively to reduce construction costs, while improving the structure of Dome City, changing the whole city from a large dome to a series of small dome in series, reducing the structural requirements and construction difficulties of dome, and further reducing construction costs.


    After repeated calculation, the cost of this scheme is 60% lower than the original cost, and the project is easier to build. At the same time, because it is the design of multiple domes, multiple domes can be built at the same time, which greatly shortens the construction period.


    Moreover, the small dome in this scheme can be separated and built separately. In small places such as counties and towns where there is no need for large dome, the dome can also be built to improve the local living environment.


    This scheme soon moved the high-rise, especially the design of the small dome, which made the high-rise feel excited and satisfied.


    After all, even if a country wants to build a large dome, it needs to consider whether it can afford to build it, but if a small dome is just a place, it can afford to build it.


    The plan was soon adopted, and the high-rise also decided to officially restart the construction plan of the dome city.


    The first step for the high-rise to restart the Dome City construction plan is to plan a new Dome City around the dome new city.


    In fact, this was only a part of the original Dome City construction plan. In addition to the dome new city, the state also selected seven surrounding areas suitable for the construction of dome cities, and planned to build a total of five dome cities.


    The construction period of the whole plan is 50 years. Some of the five dome cities are dedicated to ecological research, industrial production and scientific and technological research and development. Of course, there are also cities dedicated to living and living.


    It can be said that the original planning had the concept of Chen Xin. Now he has pieced together a city through a small dome, and five dome cities have been pieced together to become a big city.


    But now this plan is obviously impossible to achieve, but the original location of the city can be used.


    However, Chen Xin has different views on this. He does not support directly starting to build a new Dome City, but suggests building a small dome next to the dome new city to verify the technology.


    After a brief discussion, the senior leadership agreed to Chen Xin''s proposal.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "Dad, mom, I''m back." Chen Xin opened the door and said hello to his parents.


    Although he has basically lived in the scientific research center for a long time recently, Chen Xin still goes back to dome new town to accompany his parents every weekend.


    "Back? How''s your work recently?" Chen Xin''s father looked at his son and asked with concern.


    "It''s going well. The state plans to expand a new urban area in the new city, so I''ll stay in the new city and supervise the construction during this period." roughly explained to my parents, Chen Xin didn''t talk in depth. He didn''t like to talk about work with his family, especially many things he involved were confidential.


    Chen Xin''s father didn''t ask much. He knew that his son did a lot of work that he couldn''t say to the outside world, so he didn''t ask much. He just cared about Chen Xin and didn''t ask any more.


    However, hearing that Chen Xin said that he would expand the new city here, Chen Xin''s father was still somewhat curious: "expand the new city? What is the new city used for?"


    "It is mainly used as a residential area. The population density of the new town is too large. After all, it was designed to accommodate only 60000 people, but finally more than 100000 people were crowded in. Considering the floating population, the total population of the new town is nearly 200000, so it must be expanded, otherwise the city will be too crowded." these are not secrets, So Chen Xin explained to his father.


    In fact, these things do not need to be kept secret. You can find them by paying attention to them in the new town.


    After all, the new town accommodates more than 100000 migrants from the original urban area. In addition, Titan factory was built here to support the war. After various supporting facilities were built, a large number of workers worked here, which not only made the new town prosperous, but also made the city more crowded.


    The living space in the city is limited. Many residential buildings were urgently built at the beginning. It is inevitable that there is a lack of reasonable planning and design because of speed. Many residential buildings are only able to live, far from being comfortable.


    However, even so, these residential buildings are also overcrowded. If there were not war factors before, the whole city was under the wartime system, and various social problems were suppressed, I''m afraid various social problems would have erupted in the new city.


    It is undoubtedly a good thing to build a new urban area and divert part of the surplus population from the past.


    "This is quite good. There are really too many people now. Even our community can feel that there are too many people living in it at ordinary times." Chen Xin''s father nodded and seemed to support it very much.


    In fact, this is also a feeling. The community where Chen Xin''s parents live is the first batch of communities built in the new town. It belongs to the community built according to the original design drawings. Both the environment and supporting facilities are very good.


    It is mainly for people assigned to municipal departments and scientific research institutions. Chen Xin can settle his family here because of his identity.


    However, even such a community is now full of people, and the green area planned in the community was not completed in time at the beginning. Later, when a large number of people moved in, they directly flattened and built movable plank houses in order to solve the housing problem.


    Originally thought it was just temporary resettlement, but now these plank houses have been covered, not only the planned green belt, but also two-story movable plank houses have been covered on the roof of each resident''s building, and these plank houses have been filled with people.


    It can be seen from this that the population here in the new town is crowded to what extent.


    It''s not that the state has never thought of a solution, but it has been fighting for the past two years. The state really can''t spare the energy to build a resettlement community. Therefore, the population resettlement problem on the side of the new town has been delayed again and again. It can only be solved temporarily by building movable plank houses, but can''t fundamentally solve the problem.


    However, this expansion of the new urban area can finally solve this problem once and for all.


    "The father and son talked and came to dinner." Chen Xin''s mother brought the prepared food to the table and interrupted the father and son''s conversation.


    Chen Xin and his father had to stop talking, stood up and walked to the restaurant.


    "Wow, it''s so rich today!" Chen Xin looked at the food on the table and couldn''t help but praise it with exaggeration. Then he took up his job.

 Chapter 829

    Chen Xin returned to the new city after the construction of the new dome began because he had to supervise the work in the new city.


    As for the scientific research center, thanks to the blessing of Xiyao, Chen Xin can connect through the network to let Xiyao send him the things to be handled in real time, so that he can handle the things in the scientific research center in time even in the new town.


    Xiyao''s own computing power and Chen Xin''s preset logic operation module ensure that she can handle all kinds of trivial and complicated affairs in an orderly manner.


    This also makes that although there are still many affairs to be handled by Chen Xin in the scientific research center, his work has not increased much with the assistance of Xiyao.


    "It''s really convenient for Xiyao to help you deal with all kinds of things!" Tang Tang Tang watched Chen Xin easily deal with all kinds of things that Xiyao had classified on the tablet, and couldn''t help but make a voice of envy.


    As the general manager of the whole scientific research department, Tang Tang Tang has to deal with many and complicated things every day. Even if she has two deputies and three secretaries to help her deal with various affairs, Tang Tang Tang still feels that she is busy every day.


    If she also has an AI like Xiyao as an assistant, I think she can be much easier.


    Chen Xin listened to Tang Tang Tang''s admiration, smiled and said, "sister, you can also send the things you need to deal with to Xiyao and let her help you deal with them. As long as you input your information into Xiyao''s system, I can give you permission after approval."


    "But this is just my manual input of information. Unlike you, this is to let Xiyao take the initiative to help you deal with all kinds of information. It means that I have to tell Xiyao all kinds of affairs first, and then send the results to me after she handles them. This will not reduce much work for me." Tang Tang Tang Tang only thought a little about Chen Xin''s suggestion, but she added: "Unless you can make the new town realize networked office and connect the whole office system to Xiyao, the results are almost the same."


    Tang Tang''s words just expressed the actual situation. However, Chen Xin seemed a little surprised after hearing what she said: "isn''t the new town networked office?"


    "My Lord, did you forget that many supporting facilities were not perfect at that time because of the temporary opening of the new town? Although the network and other equipment have been gradually supplemented in the past two years, the office network, like the so-called network office before the disaster, is only used to send emails and information. Many specific affairs are not handled through the network Tang Tang looked at Chen Xin helplessly and explained to him in detail.


    Although Chen Xin is a gifted scientist, he is very confused about these things.


    This reminds Tang Tang Tang of when he was in school. At that time, Chen Xin, like now, was always able to put forward a lot of good ideas, but there are often some deficiencies in details when the specific implementation and implementation are put into practice. She needs to tell him the truth.


    However, Tang Tang has no opinion on this, because Chen Xin''s ideas can often bring better results than her ideas, but his character is not suitable for leading others, but more suitable for being a person who puts forward ideas and lets others implement them.


    Now Chen Xin and her cooperation mode is actually no different from that in those years. Chen Xin still puts forward ideas. She is responsible for dealing with various problems arising from the implementation of ideas, but now Chen Xin is a leader and she is a deputy.


    "So..." Tang Tang Tang''s explanation finally made Chen Xin understand the situation, which also made him a little embarrassed. After moving to the new town, he was busy with all kinds of things. In the middle, he went to Europe for another year. There were indeed omissions in the situation and all kinds of things here.


    Tang Tang''s explanation with resentment also made him feel a little embarrassed and wanted to make up for it.


    So after thinking about it, Chen Xin said to Tang Tang Tang: "I remember there is no supercomputer in the new city, but there is also a large computer? Connect this computer to Xiyao''s network, and I will install a Xiyao subroutine in it to assist in handling various affairs. I should be able to share some work with you."


    "It would be better if we could strengthen the office network in the new town. Now the networking in the new town is really not as good as the original scientific research center." the scheme given by Chen Xin has helped Tang Tang Tang a lot, but she still couldn''t help mentioning the bad office network in the new town.


    In this regard, Chen Xin just smiled at her and said, "sister, you are the director of the whole department. Don''t you just make a report and ask to upgrade the office network?"


    "It''s easy to say. Do you think I haven''t made a report? But what can I do if it doesn''t approve me?" Tang Tang felt even more helpless.


    In the year Chen Xin went to Europe, Tang Tang discovered these problems long ago, and she has been reporting to the above for improvement.


    However, due to the fact that the whole country was in a state of war at that time, all kinds of materials were given priority to the battlefield, and her report was always shelved, so the matter was delayed.


    Now that Chen Xin''s old story was mentioned again, Tang Tang Tang complained to him.


    After Tang Tang Tang explained the reason, Chen Xin couldn''t help touching his nose. In fact, it''s not to blame the above, because in the state of war, everything will take the needs of the battlefield as the top priority. If a scientific research institution in the rear wants to upgrade the office network, it naturally seems to be a feasible thing, so there is no approval at all.


    But now that the domestic war is over, it''s not that we can''t mention it again.


    Especially now, when the new urban area is to be expanded, the construction team is ready-made. It is entirely possible to make a report and upgrade the research environment here in the new city.


    Chen Xin determined his idea, so he said to Tang Tang Tang: "sister, you go and make statistics. In addition to the office network needs to be upgraded, there are other things that need to be done. Sort them out together and make a plan for me. This time, expand the new urban area, upgrade the research environment here in the new city and improve various facilities."


    "OK, first connect the mainframe in the new town to Xiyao''s system and let her help me do it." Tang Tang obviously won''t miss the opportunity to save himself a little.


    When Tang Tang Tang said this, Chen Xin smiled freely and freely. He simply stood up and said to her, "OK, just take advantage of now. I happen to have time."

 Chapter 830

    The news of the expansion of the new urban area soon spread in the new city as the construction began.


    There is no way. After all, the new city is close to the dome of the new city and starts to break ground. It''s hard to know about the new city.


    The news also made people in the new town floating. Almost everyone was discussing whether they could have the opportunity to distinguish a good house in the new town.


    This is a very realistic topic.


    In the new town, only when it was relocated at the beginning, some of the houses that had been built had relatively good living conditions, sufficient living area and relatively good supporting facilities.


    Later, because a large number of people need to be resettled quickly, most of the houses are mainly movable plank houses or tube shaped buildings built quickly. Although it can not be said that they can''t live, at least in terms of living conditions, they are not so satisfactory.


    In some worse places, the living environment is even worse than the previous underground shelters.


    However, the situation was special at that time. We were thankful to have a place to live and could not expect more.


    Now, with the expansion of the new urban area imminent, it is obvious that a number of new houses will be built, and these houses will be used to accommodate the surplus population in the new town, which undoubtedly makes the people of the new town have extra expectations.


    Many people are imagining that they can move to the place where they live and live in a spacious and bright house.


    But obviously, even if the new urban area is expanded, only some people can live in the new urban area. After all, the new urban area is only used to accommodate the surplus population, not to relocate the owner of the new city again.


    In fact, the area of the new urban area is about a quarter of that of the new city, and the designed population is 40000.


    In addition to housing, relevant supporting facilities will be built in the whole new urban area to ensure the living needs of the resident population.


    "Eh? Can the new urban area accommodate only 40000 people?" a researcher couldn''t help showing his surprised expression when he heard a friend participating in the project say so.


    The researcher''s friend is a designer. He has been involved in the design of the Dome City in the scientific research center before, and recently returned to the new city to participate in the construction of the new city.


    The researcher knew that he was involved in the construction of the new urban area, so he naturally came to him to ask for some gossip.


    "Yes, the design is a small dome, which can accommodate 40000 people on the premise of ensuring the living needs of the resident population, so the new urban area is not as good as you think. The houses will be built relatively densely, but the supporting facilities will be relatively perfect. In general, it is more comfortable than living in the movable plank house on the side of the new town." the designer explained to the researcher, Because he knew the specific information, he didn''t care much about whether he could live in the new urban area.


    But the researcher obviously cares about the house in the new urban area. He now lives with his parents and family. The living space is only 50 square meters. In addition to his parents, he also has a sister. It is very inconvenient for four people to live together.


    And recently, he is planning to marry his girlfriend who talked about marriage before the disaster, so he also hopes to take this opportunity to move out of his home and live with his beloved girlfriend.


    "What is the house like in the new urban area? Is there any standard for room distribution? If there is any internal news, tell your brother!" the researcher listened to the designer. Since he wanted to come to the designer to participate in the project, he must know some gossip.


    Hearing the researcher''s question, the designer couldn''t help grinning: "internal news? Yes, want to know?"


    Researchers and designers are classmates in the same dormitory in the University. Although they are not a major, they have lived together for four years. Naturally, they know what virtue each other is.


    Seeing the designer''s smile, he immediately guessed his purpose, so he hurriedly said, "talk about it! It''s a big deal to invite you to dinner later!"


    "Well, you owe me a meal!" it is undoubtedly very good for the designer to knock a meal. He smiled happily and whispered to the researcher: "Houses in the new urban area are roughly divided into three specifications: 70, 50 and 30. The 70 flat is for married families with more than two children, the 50 flat is for married families with only one child, and the 30 flat is for married families without children.


    If you want to apply for a house in the new urban area, I suggest you and your girlfriend go to the civil affairs department to register for marriage, otherwise you can''t apply for a house in the new urban area if you are single. "


    "Is this news true or false? Is it reliable?" the researcher was skeptical, but he couldn''t give evidence to question, so he had to confirm it to the designer with a skeptical attitude.


    However, the designer clapped his chest and promised him: "I believe my brother is right. What I said has been written into the design requirements. For a small house of 30 square meters, there should be a living room and bedroom, considering the use of husband and wife''s residence, with standard kitchen and bathroom space.


    Moreover, kindergartens and schools will be built in the new urban area, which are prepared for husband and wife families. If they are prepared for singles, don''t design these at all.


    If you really want to apply for a house in the new urban area, it''s certainly right to register with your girlfriend first! Then you only need to explain that it''s a new marriage when applying, and you need to approve the marriage house! "


    What the designer said was clear. The researcher hesitated for a while. Then he gritted his teeth and made up his mind. He nodded fiercely before he said to him, "OK, I''ll ask for leave in the afternoon and take Xiaohui to register for marriage! If this happens, I''ll thank you for your whole life!"


    "It''s serious all my life. Just invite me to have a good meal." the designer looked at his friend and finally made up his mind. He didn''t take advantage of the fire, but happily let him remember the treat.


    "OK! Xiaohui and I will invite you to eat the best!" the researcher nodded heavily, turned and ran to ask for leave.


    Watching the researcher run away, the designer''s heart also gushed out a sense of accomplishment, which contributed to a marriage.


    In fact, he had long watched the researcher want to get married, but he was worried that his lover could not get married for various reasons. This time, he finally took advantage of this opportunity to push his friend. He still had a sense of achievement.


    Just when he was happy, he suddenly heard someone say, "although it''s good to help friends, we can''t forget the confidentiality regulations we should abide by!"


    Hearing this sound, the designer quickly looked back and saw Chen Xin and Tang Tang Tang standing behind him. He quickly greeted them: "academician Chen! Director Tang! I..."


    He just wanted to explain. Chen Xin waved his hand to show him that he didn''t have to be nervous: "I can understand helping friends, but the confidentiality regulations that should be observed should still be observed. Don''t say anything that shouldn''t be said. I won''t investigate this time. Remember to ask your friends to keep it confidential."

 Chapter 831

    After reminding the designer to pay attention to the confidentiality regulations, Chen Xin and Tang Tang Tang let him go.


    Looking at the designer''s embarrassed escape, Chen Xin couldn''t help laughing at Tang Tang Tang: "do you think he looks like us caught by the teaching director in those years? When we secretly cooked hot pot in the community activity room and the teaching director came in, I remember that we seemed like this?"


    "Aren''t we the same at that time? We were caught by the teaching director cooking hot pot in the club activity room and violating the regulations on the use of electrical appliances. If the director hadn''t let us go, I''m afraid we would have to be criticized that time. At that time, I was scared to death." Tang Tang Tang Tang couldn''t help sighing when he heard Chen Xin mention the past, but she quickly restrained these emotions, He turned to Chen Xin and asked, "Xiao Chen Xuedi, do you intend to apply for a house in the new urban area only for married couples?"


    "Well, the population pressure in the new town mainly comes from the newborns in the past two years. It''s OK to be an adult. You can tolerate being crowded at all, but if you want to raise children, the current living environment is obviously unfavorable to the growth of children." Chen Xin nodded definitely, which explained to Tang Tang Tang Tang: "The purpose of expanding the new urban area is not only to solve the problem of excessive population density in the new town, but also to provide a good growth environment for the next generation in the new town.


    Therefore, when designing the new urban area, I asked them to take the use of husband and wife as the main design premise, and added kindergartens and schools.


    After all, the country now needs to consider the problem of population growth. If there is no good reproductive environment, everyone doesn''t want to have children, or the parenting environment is too poor, which affects the survival rate of newborns, which is not a good thing for the country. "


    Tang Tang naturally agrees with Chen Xin''s remarks.


    From the disaster to now, the environment of the whole blue star has changed greatly, and people''s living environment has also changed greatly.


    Under such circumstances, many couples are obviously unwilling to have children. After all, the environment is too bad. After birth, the husband and wife may not have enough energy to take care of the children, not to mention that in the current environment, it is troublesome to provide sufficient and comprehensive nutrition for the growth of infants and young children.


    Therefore, creating a relatively good growth environment is a great help to the future population problem of the country.


    After all, before the disaster, there was a trend of population aging in Yanguo. If this generation of young people reduce fertility because of environmental problems, the population of Yanguo will inevitably decline sharply with the gradual death of the elderly in the next few decades.


    Although at the beginning of the disaster, a large number of old and weak people died due to physical reasons, which has changed the population structure to a certain extent, the proportion of newborns does not increase, and the problems caused by population aging are still visible to the naked eye.


    Moreover, in the current environment, the consequences of population aging are much more serious than before the disaster.


    Before the disaster, it was nothing more than the decline of social vitality and the shortage of labor force. But now, the decline of population leads to the lack of sufficient labor force, which will affect all aspects of the whole country and may even lead to a serious social crisis.


    In fact, there are also considerations for the state to restart the construction plan of the dome city.


    "That''s true. I know there are several couples who got married in the past two years, but they have no plans to have children." Tang Tang Tang nodded definitely. The couples she knows don''t want children, largely because they have no place and have no time to take care of themselves.


    Thinking of this, she couldn''t help reminding Chen Xin: "having a house to solve the problem of living can only say that some difficulties have been solved. Many people are too busy to take care of their children. How can we solve this? Kindergarten alone is not enough?"


    "This is also a matter of no way. What we can solve is the difficulties in material conditions. As for the problems that both husband and wife are busy and have no time to take care of children, our parents can raise us. I think people of our generation should also have no problem." Chen Xin doesn''t have a good way to solve this problem. It can''t be said that because parents don''t have time to take care of their children, they give them a holiday?


    And just as Chen Xin said, his parents'' generation also went to work every day, and both husband and wife went to work. There is no preferential treatment for this generation of young people''s parents to help take care of their children. Doesn''t it also expand Chen Xin''s generation?


    Therefore, Chen Xin feels that this can be overcome at least. It is not like hard material conditions such as house and education that can not be overcome by individuals.


    Tang Tang has no intention to argue with Chen Xin about this matter, so he didn''t say much. After all, her identity is different from that of Chen Xin. Chen Xin''s ideas and opinions on these matters will be used as a reference for high-level policy-making, and Chen Xin can also get a lot of information that Tang Tang Tang can''t get because of her identity. Tang Tang Tang doesn''t think her views will be better than Chen Xin.


    "Do you need a hint to let some people who don''t plan to get married now take this opportunity to get married? I think couples who don''t plan to have children can also blow the wind." Tang Tang Tang just put forward his own suggestions according to what Chen Xin said without arguing with Chen Xin about how couples should squeeze out time to take care of their children.


    In the face of Tang Tang Tang''s suggestion, Chen Xin touched his chin and thought about it and said, "you can give married couples a hint. It''s still a little inappropriate to let others rush to get married. After all, marriage is not so simple."


    "Well, I''m just making suggestions." Tang Tang Tang nodded slightly, but suddenly remembered something and asked Chen Xin, "what about younger brother Chen? When will you get married? Qin LAN and Mo Qingyan, who do you want to choose?"


    "Don''t embarrass me about this, sister Xue. Qingyan and Aran are crazy about who I choose. Now the three of us can survive. If I really make a choice, that''s the worst thing." Tang Tang Tang''s inquiry obviously poked Chen Xin''s biggest pain point and made him frown at once.


    Tang Tang obviously didn''t support Chen Xin''s attitude. He frowned at him and said, "I understand you don''t want to hurt them, but you always have to give them a result for this kind of thing, don''t you? The longer you delay, the greater the damage to them. Sometimes it''s difficult to make a choice, but it''s better to choose than not."


    "No, sister, don''t force me. I really let me make a choice. At least one of the three must be crazy." Chen Xin shook his head and bitterly rejected Tang Tang Tang''s proposal.

 Chapter 832

    Relying on various so-called "internal news", the news that the distribution of housing in the new urban area will be dominated by couples with children soon spread.


    Because of the instructions given by Chen Xin and the policy set by the senior management long ago, the municipal government on the side of the new town did not control the rumors. While allowing the rumors to spread, it was also secretly preparing for the future housing distribution.


    Send grass-roots staff to make statistics on the existing residents, classify them according to the situation, and preliminarily count the number of people who need to be divided.


    Then, according to these preliminary statistical results, make a preliminary distribution plan in combination with the number of houses in the new urban area


    Although the new urban area is still in the stage of laying foundation, these preparations have been carried out in an orderly manner.


    The construction of the new urban area is progressing smoothly, even to the point of lack of success.


    If it is a large dome, it may also cause some difficulties due to high construction requirements and great difficulty, but the construction difficulty of the small dome with only a quarter of the area of the large dome in the new urban area is much less.


    In addition, the construction team uses 3D printing equipment to build the dome of the new urban area, which has greatly improved the construction efficiency in terms of construction difficulty and speed.


    Even after the foundation is leveled, data classification is still being done in the new town, where a third of the dome and most of the houses have been built.


    Although most houses are only rough with 3D printing technology, they have begun to take shape.


    As the person in charge of the project, Chen Xin naturally wants to inspect the construction of the new urban area, and the inspection results are undoubtedly satisfactory.


    3D printing technology is not a new invention. The 3D printing equipment developed by Chen Xin only makes this technology more practical and more convenient to use.


    As for building a house with 3D printing technology, in fact, this technology had been applied long before the disaster.


    Moreover, the built house has great advantages in earthquake resistance, thermal insulation, sound insulation and other performance, construction speed, saving building materials and so on.


    However, before the disaster, Yanguo was a large infrastructure country with a large number of construction workers. At the same time, the land was relatively expensive, and 3D printing construction was obviously not very suitable. Therefore, although it had the world''s advanced 3D printing construction technology, the application of this technology was not very extensive.


    However, in this environment, 3D printing construction technology has been widely used in order to save building materials and reduce construction time.


    In addition to the construction of domes and buildings in the new urban area, this technology has also been applied to the construction of the Middle East defense line.


    According to what Chen Xin learned, because of the wide application of 3D printing technology, the construction speed of both equipment and fortifications is at least twice that of the same period, and the work efficiency has been greatly improved.


    The construction speed in the new urban area is no less than that. When Chen Xin inspected, he can even see that the first floor buildings are gradually built with the naked eye.


    "Academician Chen, the wall built by the 3D printing technology we are now using is such a hollow structure. The interior is filled with this wave line to stabilize the structure, which not only saves building materials, but also improves the construction efficiency. If it is built manually, it will consume more construction efficiency and building materials than it is now." The Engineer in charge of on-site construction explained to Chen Xin with a proud face. Obviously, he is very proud of this 3D printing architectural technology.


    Chen Xin can understand the pride of the engineer. In fact, he looks the same when explaining what he has made.


    Therefore, Chen Xin did not interrupt the engineer''s explanation, but let the other party play freely.


    Just noticed that after the wall was printed, the workers filled the wall with a kind of white debris. Chen Xin asked curiously, "what are you adding here?"


    "It''s thermal insulation material. Because the construction requirements stated that thermal insulation should be done, we filled this thermal insulation material. The main components are asbestos and glass fiber. In addition to thermal insulation, it can also effectively play the role of sound insulation, and the effect is very good." the engineer explained to Chen Xin, and took some thermal insulation material from the bag on the side, Took it in his hand and showed it to Chen Xin.


    After a simple look at these thermal insulation materials, Chen Xin nodded with satisfaction: "you did a good job. The construction progress in the new urban area is faster than expected, which is very good. We should continue to maintain it. In addition, we should pursue the construction speed and not neglect the construction quality. We must ensure that everything meets the construction requirements and standards and there are no potential safety hazards."


    "Don''t worry about this, academician!" on this issue, the engineer seemed confident. He pointed to the 3D printing equipment working on one side and said: "people may make mistakes and be careless, but the machine will not make mistakes or be careless. Our engineering quality is definitely better than that built manually!"


    It''s true that people may make mistakes, but as long as the machine doesn''t break down, it won''t make any mistakes, and the project quality is absolutely stable.


    Therefore, Chen Xin just smiled and encouraged the engineer''s attitude.


    After explaining a few words, Chen Xin came to a building that had been capped and began to be decorated by decorators. He checked a house that had completed the initial decoration.


    This is a 50 square meter house. According to the design plan, there are two rooms and one living room. The kitchen and bathroom facilities are complete, which can be used for a family of three.


    Because the total area is only 50 square meters, although the designer has spent a lot of effort on decoration to improve the comfort of use, the room is still not large on the whole.


    The two bedrooms are of the same size. One can be used for husband and wife, and the other can be used as a children''s room. After all the decoration, the children''s room can also be divided into two relatively independent spaces.


    If the family''s population continues to increase, it can apply for a bigger house.


    Although according to the regulations discussed at present, families with two children over the age of 5 can apply for a 70 square meter house, it will be controlled as much as possible according to the situation.


    And even if you apply, you may eventually get a house of 50 square meters, because the number of houses of 70 square meters in the whole new urban area is not much, accounting for only about one fifth, while the houses of 50 square meters are the most, and two-thirds of them are this house type, but they are different in internal decoration and internal space division according to the number of children.


    As for the rest, it is a 30 square house type for newly married families without children or families ready to raise children.

 Chapter 833

    People who want to divide houses obviously account for the majority in the new town, and this proportion is still rising with the completion of the new urban area day by day.


    Families with children naturally Miss kindergartens and schools in the new urban area and want to give their children a good living environment.


    Couples without children are busy having children during this period because of the so-called gossip. At the same time, they also think about the more comfortable living space in the new urban area.


    After all, with the gradual completion of the new urban area, the overall situation of the whole new urban area is gradually revealed, which is obviously more reasonable than the planning of the new town, more perfect supporting facilities and more beautiful green environment


    These are deeply attracted to the people in the new town who have to live in a family of three or five because of the excessive population, or even more people crowded in a movable plank house or a narrow tube building.


    However, it is obvious that only about 40000 of the more than 100000 permanent residents here in the new city can move to the new urban area.


    As for the remaining nearly 100000 people, what should we do? Obviously, it is impossible to leave these people directly in their original residence.


    In order to solve this problem, the municipal government held a municipal meeting for discussion, and Chen Xin was naturally invited to participate in the meeting.


    "I suggest that some movable plank houses be demolished, some open space be vacated to build new residential buildings, and the original residential community be re planned. Taking this opportunity, the unreasonable planning of the new town caused by haste should be adjusted, and the supporting living facilities should be improved." at the municipal meeting, a vice mayor is expressing his views.


    In fact, this proposal is largely nonsense, because what the municipal council wants to discuss is how to deal with these problems, not whether to deal with them.


    Of course, even if this kind of meeting particularly emphasizes the efficiency of the meeting and does not engage in bureaucratic articles, such "nonsense" is still necessary. After all, it is necessary to open the topic.


    Sure enough, after the vice mayor finished, a municipal official followed up and began to explain what can be demolished in the current urban area of the new city.


    The overall area of the new town is not large. After all, it is only a dome city originally designed to accommodate 60000 people, so there are not many places to move.


    According to the prediction of the municipal department, after 40000 people are moved from the existing urban area to the new urban area, most of the ecological circles and green areas that can be demolished are originally planned.


    At the beginning, for rapid resettlement, these areas built movable plank houses that are relatively easy to dismantle, and because of the problem of the structure of movable plank houses, the number of people accommodated is not too much. Therefore, in terms of demolition, as long as people can be moved out, the demolition is not difficult, and can be completed quickly in a short time.


    However, this does not mean that the problem is easy to solve.


    After all, the previous urban planning has also been carefully designed. Although the part of the ecosystem is not needed now, this does not mean that the vacant plots after demolition can be built at will.


    Playing construction games also pays attention to the layout of a city and the division of functional areas. A real city like this will only involve more problems.


    Therefore, how to use these plots and what each plot is used for are issues that need to be seriously discussed.


    This is also the main content discussed at this meeting.


    After some statistics, people from the Municipal Department said that about nine plots could be vacant. At the same time, in order to adjust the urban layout and improve the existing living environment and space, at least two large plots should be used for the construction of residential communities to accommodate the relocated population in other places, so that construction can be carried out in other places.


    As for the remaining seven plots, it is obvious that they have become the object of contention among various departments.


    "Another high school should be built in the urban area. At present, the high school in Xincheng has been overloaded with the graduation of this junior middle school graduate." people from the education department took the lead in putting forward their own needs.


    No matter how poor you are, education cannot be poor. For the country, educated talents are undoubtedly a very important part of the labor force, so education has always been the top priority. Even in the current environment, students'' courses have not been delayed at all.


    Therefore, when the education department proposed to build a high school, other departments did not object, so they directly designated one of the plots as education land.


    Of course, even if a high school is built, it is still a little big to directly delimit an entire plot. Therefore, someone proposed to build a smaller residential community outside the high school.


    The education department obviously doesn''t want to agree to this proposal. How can the meat that has been put into the mouth spit out again.


    However, the education department itself knows that it is more than enough to build two high schools on the plot allocated to them. If they want to keep the whole plot, they must think of other ways.


    However, at this time, Chen Xin suddenly asked, "there is no vocational and technical school here in the new city? I propose to build another vocational and technical school next to this high school. After all, there is still a great demand for skilled workers in various places. After graduating from high school, you can become a qualified worker after a year or two of Vocational and technical training, can''t you?"


    If before the disaster, Chen Xin suggested that high school students go to vocational and technical schools after graduation, it would undoubtedly be bloody.


    After all, before the disaster, most high school graduates would still choose to continue to study in college, thinking that they would seek a good background in the future. Only some people who did not get enough grades to go to college would choose vocational schools.


    But obviously, the social environment has changed. It has become not so easy to take the college entrance examination after graduating from high school as before.


    Although all localities can still guarantee nine-year compulsory education and high school education, it is obvious that after the traffic is cut off, it is undoubtedly very difficult to go to college in other places.


    It''s easy to say that there are local universities. Based on the principle of studying nearby, we can still have books to read. The state is also trying to maintain the teaching and academic research level of these universities and ensure the source of students, but it''s impossible to face the national enrollment as before the disaster.


    Moreover, there is a shortage of labor in various places. Compared with the academic talents trained in four years in universities, the skilled workers trained in Vocational and technical schools are more popular.


    Therefore, when Chen Xin put forward the proposal to build a vocational and technical school, everyone did not oppose it. On the contrary, after a while of discussion, they agreed to his proposal.


    Of course, if you have the opportunity to go to university, you obviously prefer to go to university, and the national demand for highly educated professionals is also not small. Therefore, while paying attention to the training of Vocational and technical workers in Vocational and technical schools, we should also pay attention to university education.


    But this is obviously not the subject of this municipal meeting.

    Finally, of the nine plots, only five can be used to build residential communities. One plot is taken away by the education department to build a comprehensive high school, which includes both ordinary high school courses and vocational and technical school courses, which is equal to two academic systems of one school.


    Such a school setting model naturally has its advantages, that is, in addition to the normal full-time high school courses, students can also learn some vocational skills. After graduation, they can either choose to continue their further study to enter the university or choose to get employed.


    The school system is also divided into two types. One is full-time high school, which normally studies high school courses, but after graduation, those who can enter the University naturally go to the University, but those who fail to enter the university can stay in the school for one to two years of vocational training, and then go to work.


    The other is to receive vocational training at the beginning, but the courses also include cultural courses required by normal full-time high schools, but it takes more than one year than ordinary full-time high schools.


    If you choose this school system, you can also choose to work directly after graduation, but at the same time, if you make progress, you can also go to college if your grades are good enough.


    As for the remaining plots, one of them was jointly taken by the hospital, fire department and public security department to build the hospital, fire brigade and Public Security Bureau.


    The previous three departments naturally had office space, but they were all temporary facilities, so the hospital was better. They were assigned to a fairly good building, but it was not a special hospital.


    Therefore, this time, we will take this opportunity to simply rebuild it, so as to provide better services for the people.


    Naturally, no one objects to the construction of such public service facilities, and only one plot is taken by the three departments, which is very economical compared with the education department directly taking one plot. Naturally, there is no problem with the use of this plot.


    In the last two plots, one of the municipal government originally wanted to build a new municipal office building, but it is obvious that the project of municipal office building must be put back.


    Therefore, although this plot is indeed reserved to be used as the land for municipal office buildings, it will be used as a temporary resettlement area to temporarily relocate people from other residential areas here, and then demolish and rebuild the emptied residential areas to improve the original housing conditions.


    As for the last plot, it is planned to build a park at Chen Xin''s suggestion.


    After all, the new town was originally planned as an ecological city. Although the plan of the ecosystem has been removed and the green space in the original plan has been misappropriated for other purposes, it is obvious that there can be no green in the city.


    At the beginning, various departments were naturally unwilling to use valuable plots of land to build parks. You should know that although the new city can move 40000 people to the new urban area, there are still more than 100000 people in the city. How to protect their lives and improve the living environment so that the residents of the new city will not have resentment because someone moves to the new urban area is still a very severe test for the municipal government.


    However, after some discussion and persuasion, the city government agreed to this decision and used one of the valuable plots for the construction of the park.


    In addition to the reasons that the park can provide entertainment and leisure places for residents, improve the urban environment and improve the happiness index of residents, the project cost of the new urban area shown by Chen Mo to the municipal government is the place that moves the municipal government''s leadership most.


    Because after accounting, the leading group of the municipal government found that the project cost of the small dome in the new urban area is really "not expensive". If the municipal government tightens its belt, it can save enough to build a family in the new urban area within three to five years.


    In other words, as long as the municipal government is willing, they can expand a new urban area in five years, and then completely adjust the urban planning and layout to a reasonable and comfortable mode.


    The five-year period is neither long nor short. If the city is destined to be re planned and adjusted after five years, it is better to solve all kinds of problems now and make good planning, so as not to fight again after five years.


    This is also the main reason why the municipal government agrees to build the park, because if a small dome can be added, the space in the existing large dome of the new town will be much looser, and more plots can indeed be used to plan other urban buildings except residential areas.


    Of course, the main reason here is that the plot used to build the park is not large. If it is used for other things, one project is too large to fill the two projects. After weighing it, the municipal government found that only building the park is the most suitable.


    After all, the idea and theme of urban layout and planning are different from those before the disaster. The plot does not need to think about how to attract investment, or build buildings and sell land.


    The main purpose of the municipal planning of the new town is to engage in municipal construction or resettle residents.


    Although there is also a planned business district in the new town, the business district, like the department stores in the 1980s and 1990s, is mainly used to provide residents with materials other than various necessities of life. Just like people in that era would not go to department stores easily, there is no one to go at ordinary times, so the scale of the business district is not large.


    As for the other five plots used as residential areas, there is nothing to discuss. The purpose has been determined. Naturally, the design department will work on how to design the community.


    However, the design department has also reaped some benefits in this matter, that is, they have won some space on the plot used to build the park, and they can build a small building as the office of the design department.


    Of course, the main reason why the design department can strive for this benefit is that the design department itself has few people, and the place used to build a building for office is not large. There was no suitable land before. Now that there is land, it is not difficult for the design department to strive for some benefits for itself.


    After all, they are the city''s own design department. They have to come for these municipal planning and design. Other departments don''t want them to make themselves unhappy when making design drawings.


    You know, designers don''t need to be specific to you when designing houses or other buildings. They just need to move the position of elevators and stairs a little, and your whole building will suffer.


    And you can''t change this kind of thing in the future. After all, this is a house, not something else. It''s impossible to say that I''m not satisfied with the demolition and reconstruction.


    Therefore, although the design department usually looks like a Yamen with clear water and no mountains and dew, at this critical moment, other departments still hope to let the design department design a more comfortable office environment for their own department.


    Even Chen Xin himself plans to let the design department transform, readjust and plan the building of the current scientific research department.

 Chapter 835

    When Chen Xin was busy with the construction of new urban areas, other domestic departments were not idle.


    With the national strategic adjustment brought about by the end of the civil war, various requirements and controls under the original war mode have been cancelled, and the focus of national construction and development has shifted back to people''s livelihood, which has really improved the situation of the country in recent months.


    Instead of maintaining high-intensity military operations and consumption, a large amount of steel does not need to be used to make shells, but can be used to make all kinds of machinery and production tools to improve production conditions


    The valuable transport capacity of the railway has been liberated and there is no need to transport materials to the front line every day, which has significantly picked up the domestic material supply level


    The factory does not need to produce military products day and night, but can return to the production of civil products, which also makes the types of domestic material supply more


    In short, although the country still has to bear the burden of aid to Europe and support for the construction of the Middle East defense line, the overall situation is gradually improving, and the construction stopped because of the war has been resumed, which has obviously made the life of the Chinese people much better in recent months.


    Even the aid to Europe has been greatly improved due to the adjustment of domestic productivity, which has enabled Europe to gain many advantages on the battlefield.


    Judging from the current war situation, if alien creatures do not make some other moths, it is impossible for them to break through the European defense line, while the Eastern European defense line and the Middle East defense line are less likely to be used at present.


    However, Yanguo and Lucia have no intention of giving up the construction of these two lines of defense. On the contrary, the two countries have accelerated the two lines of defense currently under construction, and intend to take advantage of the opportunity that Yanguo''s productivity is now liberated from the domestic war to complete the line of defense across Eurasia as soon as possible, which is enough to be called the new great wall.


    Of course, this is not that the two countries have the delusion of being killed, want to waste domestic resources, or simply want to build a spectacle, but that the countries that have fought with alien creatures clearly know that there is no reason to talk with these alien creatures, and they can''t have any luck.


    It is better to spend a lot of resources to build a defense line and turn it into useless furnishings, rather than give up the construction of the defense line because the war situation is not dangerous at present.


    Instead, we should seize the time when we have advantages and improve the defense system as soon as possible. In this way, even if alien creatures can toss out any moths, humans also have the ability to resist.


    Moreover, not only the construction of the defense line, countries are also further strengthening their domestic military production and military construction. Lucians even proposed to organize the military R & D departments of various countries for cooperation and take out their technologies, so as to develop military equipment that can draw on the strengths of many countries and better meet the needs of the current war.


    European countries support this proposal very much. After all, there is often technical cooperation between European countries, and there is no problem. Moreover, now all the technical equipment used by countries to fight against alien organisms comes from the assistance of China. They are not stingy about their own technology.


    As for Lucia, in fact, they had already opened their own technology library to Yanguo as early as when they first received assistance from Yanguo.


    Moreover, due to some grievances and disputes between Yanguo and Lucia in those years, the technologies of the two countries are actually interconnected to a great extent, and there is no problem in technical cooperation.


    However, at present, it is obvious that Yanguo''s technology is the strongest among the three parties. Rather than joint research, it is still taking advantage of Yanguo to a large extent.


    Just out of the consideration of uniting all parties and the need to enhance the military strength of the other two parties in order to fight against alien creatures, Yanguo agreed to the proposal of joint research put forward by Lucia.


    After all, the military equipment of the three parties now depends on Yanguo. Of course, Yanguo''s military technology is advanced, but on the other hand, the military equipment production capacity of Lucia and European countries has also been wasted.


    If Yanguo doesn''t give them technology, they can only produce those old-fashioned equipment, and how much role these equipment can play in the battle against alien creatures has obviously been tested in actual combat.


    However, if they can play a satisfactory role, now countries will not be equipped with all the equipment of Yanguo.


    Therefore, the joint research plan was adopted. Yanguo opened the foreign trade version of major equipment against aliens such as power armor, exoskeleton electromagnetic rifle and Titan to European countries and Lucia.


    Obviously, countries can''t be stingy, and they have taken out all the technologies they can afford.


    After all, before the technical disaster of pressing the bottom of the box, we all knew each other. Although we were not forced to take out the old foundation, we could still tell whether the things we took out were good or bad.


    So even if some countries want to cherish themselves, other countries will not let him do so.


    However, although all countries have come up with their own advantageous technologies, it is obviously impossible to say that the development of new equipment is a combination of various technologies.


    Before the disaster, a San studied the main battle tank and got the most advanced mainstream technology in various countries at that time, but the thing he made was just an expensive and amazing industrial waste.


    Therefore, this joint research project mainly studies a series of equipment taken out by Yanguo, trying to apply the technology taken out by various countries to these equipment and improve them.


    In addition to these improvements, the joint research project naturally needs to develop something and achieve some results to prove that the joint research project is not an obvious project.


    In order to achieve this goal, it is natural to have a large-scale project that can produce at least some practical results that can play an important role in the battlefield.


    However, it is not easy to find such a large-scale project, because the series of equipment used by Yanguo now covers most of the equipment used in the current battlefield, except for the open land ships and mobile bases. It is not easy to develop something new.


    Therefore, all countries took out some equipment R & D plans before the disaster. Some of them were just the upgrading of active equipment in various countries at that time, while others were works with big brain holes.


    Some of these plans are reasonable, but a considerable part of them are the products of designers'' flying themselves. Although the creativity and ideas are really good and can not be used as research projects, they are obviously not suitable to be the main target of the whole joint research project.


    However, among these plans, the joint research project has selected a suitable project as their research project.


    This project is the South Tianmen plan put forward by the Yanguo military.


    www.novelhall.com, the fastest update of the webnovel!

 Chapter 836

    The so-called South Tianmen project is an aviation themed immersive experience project once displayed by the Yanguo air force at an air show. It itself is not like a military R & D plan.


    Because the things displayed are too advanced, similar to a science fiction concept, rather than something that can be truly developed and manufactured.


    The whole Nantianmen plan includes several components, such as the "Luan bird" large-scale Aerospace strategic carrier platform, "Xuannv" aerospace unmanned fighter, and the orbital airborne force equipped with unmanned tactical aircraft armor. The purpose is to create a "deep space strategic strike cluster" to effectively resist the attack of alien civilization.


    At that time, this plan was just an air show experience project similar to entertainment projects. Although relevant conceptual things have been released in the follow-up, such as the "Xuannv" aerospace unmanned combat aircraft, the relevant aviation enterprises really made a decomposition model for exhibition.


    However, the plan itself is still just a thing similar to the concept of science fiction. It can not be said that there is such a R & D plan, or that the plan does exist, but obviously before the disaster, no one will think that it is possible to realize the plan in a short time.


    However, when the end of the world came, alien creatures began to invade, and Yanguo pulled out black scientific and technological equipment like a scientific and technological explosion, the South Tianmen plan seemed to have the possibility of realization to some extent.


    Besides, after seeing the land-based aircraft carrier transformed from an aircraft carrier, no one will think that Yanguo can''t build a large-scale Aerospace strategic aircraft platform.


    After launching anti gravity flight, the land aircraft carrier itself can be regarded as an air-space carrier platform, but compared with the "Luan bird" in the South Tianmen plan, the land aircraft carrier is still slightly smaller, and the design concept is completely different.


    According to the design of Nantianmen plan, the large-scale Aerospace strategic carrier platform "Luan bird" has a total length of 242 meters, a wingspan of 682 meters and a maximum takeoff weight of 120000 tons. It can carry the "Xuannv" unmanned Aerospace fighter for long-term cruise at an altitude of more than 40 kilometers from the ground.


    In the event of a combat mission, if it is a combat mission on the planet, the orbital airborne force will be launched to cooperate with the air-space UAV for orbital airborne combat.


    If it is an enemy outside the planet, the space unmanned combat aircraft will cooperate with the strategic carrier platform to carry out space attack. It can be said that this deep space strategic attack cluster can respond effectively to the enemy both inside and outside the planet.


    It is by no means easy to build such a giant that can fly in the sky. Before the disaster, even if all countries in the world unite and cooperate sincerely, each country takes out its own technology to press the bottom of the box and fully supports the project, it is still a matter of choice whether it can build a large space strategic aircraft platform.


    After the disaster, if Chen Xin hadn''t been constantly digging out all kinds of black technology things, Yanguo wouldn''t want to build such a thing at all.


    However, as far as the current situation is concerned, building such a large space strategic carrier platform is of great practical significance for fighting with alien creatures.


    As for the technologies related to the manufacture of this big guy, Yanguo now has a small nuclear reactor and anti gravity generator in hand, so there is no problem for such a big guy to fly. As for the materials used to manufacture this big guy more than 200 meters long and more than 600 meters wide, it is not a big problem in the case of joint research by various countries.


    After all, countries now take out some really good things. Things such as high-performance alloy formulas are open. It''s not difficult to solve a material problem, just a problem of cost and cost.


    After having qualified materials, aerospace UAVs are not a problem. Yanguo''s technical R & D level in the field of UAVs has long reached the world''s leading top level. All it needs to solve is the problem of engines and materials. As for flight control, it is not a big problem.


    Therefore, after Yanguo came up with such a plan as a research project, after the countries participating in the joint research discussed and adopted the plan, they put their own excellent technology and scientific researchers into the research of the project.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    "The South Tianmen plan, I didn''t expect to actually take out all these things!" on a small land ship, Chen Xin was looking through the information of the South Tianmen plan.


    Of course, the materials that could be sent to him could not be the immersive science fiction experience project at the beginning, but the introduction materials of the serious scientific research plan reorganized and planned by the joint research project team.


    The big top secret words on the cover are enough to illustrate the importance of this information.


    "Academician, what do you think of this plan?" the researcher sitting in front of Chen Xin looked at Chen Xin and wanted to hear his evaluation of this plan.


    "Evaluation? HMM... there is no problem with the plan itself. In terms of our current technical reserves, small nuclear fusion reactors can also meet the energy consumption of this big guy. It is not difficult to get it up with anti gravity generators. As long as the material problem can be solved, everything else is easy to say." Chen Mo closed the data in his hand and put it back in the file bag: "But the investment in this plan is too high, and how long will it take to build such a large thing? Ten, eight or twenty years?


    It''s at least as big as six aircraft carriers! How many resources will it take to make it? Even if Europe and Lucia help share the resource consumption, it is an astronomical consumption. I don''t quite understand why we need to build this kind of thing now. "


    There is nothing wrong with the Nantianmen plan itself, but the Luan bird large space strategic aircraft platform is too large. With a wingspan of more than 600 meters, it is lucky that it can take off and land vertically with an anti gravity generator. Otherwise, how much runway does such a big guy need to build to make it fly?


    Moreover, the human and material resources needed to build such a huge aircraft are astronomical. Even before the disaster, no country can say that it can independently afford the whole project.


    To put it mildly, even before the disaster, Lucia was only half of the countries qualified to build such a large space strategic aircraft platform, except for the United States and the Federation. If the whole Europe can integrate all resources and cooperate together, there may be a play.


    In addition, if any country wants to build something of this level alone, even without considering technology, the consumption of labor and resources alone can completely bankrupt regional powers.

 Chapter 837

    Chen Xin''s questions were actually raised by researchers from various countries at the beginning.


    After all, the information of the South Tianmen plan is clearly there. We all know how much resources it takes to build such a thing, which is not even lower than the cost of the European defense line, the Eastern European defense line and the Middle East defense line!


    With this money, why don''t you take it to do something else? Why do you have to build such a super project? If air strike force is needed, the existing land carrier can also provide sufficient source of air force, and there is no need to develop such a large air space strategic carrier platform for low earth orbit flight.


    If it is a war against alien creatures, using these resources to build nuclear bombs is enough to completely wash the area occupied by alien creatures with nuclear bombs.


    Not to mention Titan and power armor, it can create a literally iron torrent.


    However, when discussing this plan, countries also feel that the research of such a large project can effectively integrate the technologies in the hands of countries. After all, countries have their own scientific research routes. Before technology integration, the technical styles and routes of countries are different.


    To conduct joint research, we must integrate technologies of different routes and styles.


    Such a large-scale project that requires joint research by all countries is the best way to integrate technology.


    In addition, countries also need such a large-scale project to integrate their resources.


    After all, European countries, Lucia and other countries are now grasshoppers on the same rope. The concept of a community of human destiny has never been so clear as it is now.


    Almost all the existing countries on the blue star have invested in the battle against alien creatures. If the resources of each country are not integrated or go their own way, it is impossible to concentrate all their forces against alien creatures.


    It''s good to say that Yanguo has fought a war before, and Yanguo itself has a high degree of control over its own country, so there is no problem in the use and allocation of various resources.


    Lucia has had problems before, but it has slowed down with the assistance of the United Nations and its own adjustment.


    In addition, it has also participated in the fighting in the country and supported the European battlefield, and repaired the Eastern European defense line. Lucia''s domestic resources have been integrated.


    Although it can''t be said that the allocation of domestic resources is as easy as that of Yanguo, it''s just a little close. There''s no problem.


    European countries are much worse in this regard.


    Europe itself had the Atlantic Treaty Organization led by the Federation, and it also engaged in various joint organizations, which eventually evolved into the EU. This was intended to integrate the whole Europe into a whole, eliminate obstacles between countries, and turn the whole Europe into a national union.


    However, after the establishment of the European Union, although it is indeed promoting the process of European integration, the result... The brexit of the English channel is enough to show what the union is.


    Every year, more than 40% of the administrative work of the administrative organs of the whole EU is to translate various texts. It is amazing how beneficial it is for the country and the people to have books and cars on the same track.


    Although at a critical juncture, countries still know the importance and cooperate with each other, and Chen Xin helped them adjust when he was in Europe, the problems in Europe have accumulated very deeply and can not be solved overnight.


    Coupled with the losses of European countries in their own industrial capacity and other aspects after the disaster, Europe has not brought its full strength into play at all.


    It is very meaningful and necessary to integrate and redeploy the resources of European countries through such a large project.


    Not to mention, the fundamental purpose of this project is to integrate the forces of Yanguo, Lucia and Europe.


    After all, the invasion of alien organisms has been a common problem faced by all mankind. It is obviously not wise to worry about the differences between countries.


    In fact, there is another meaning of the high-level promotion of this project, which is to take this opportunity to integrate all countries on the blue star in a real sense, so that human civilization can change from each country into a real whole.


    This does not require much insight. In the current environment with internal disasters brought by natural disasters and alien creatures as strong enemies, if mankind does not unite, it can only show that the leaders of human countries are fools.


    The joint research is a small attempt made by various countries to promote the goal of human integration.


    If the forces of all countries can be integrated to complete such a project, it will undoubtedly promote the process of human integration by a big step.


    After all, to complete such a super project is a very arduous challenge to the coordination among countries and the allocation of resources.


    To overcome these problems is undoubtedly to open up various passes between countries that hinder the process of human integration.


    It can''t be said that the completion of the South Tianmen plan can immediately turn all countries into a whole that focuses on one place, but at least for all countries, it is a foundation for better cooperation.


    In fact, when Chen Xin asked the high-level about this matter, the high-level revealed to him that after the completion of the South Tianmen plan, it was to promote the establishment of the human coalition government.


    After learning the whole story from the high-level and why the high-level should promote the South Tianmen plan, Chen Xin no longer opposed the plan, but accepted the joint appointment of Yanguo, Lucia and European countries and became the general director of the joint research project.


    Originally, all countries had ideas about this position, but the candidates were unable to convince the public.


    Chen Xin has won the common support of all countries.


    After all, he is an important researcher in Yanguo, and his contributions and achievements are obvious to all. Yanguo will not oppose him to lead joint research projects.


    Lucia also knows about Chen Xin. Chen Xin spent a year in the capital of Lucia to help them improve their people''s livelihood, which has won the favor of Lucia officials, and they have no objection to it.


    Although European countries do not agree with Chen xinlai''s leadership of the joint research project and want to replace their own people to ensure their own interests, their proposed candidates are undoubtedly not as persuasive as Chen Xin.


    After all, even European countries themselves have received great benefits from Chen Xin before. His year in Europe can be said to have completely reversed the current situation in the European battlefield, and European countries really have no face to oppose Chen Xin.


    Therefore, under the influence of various factors, the hat of the general director of the joint research project was worn on Chen Xin''s head.

 Chapter 838

    As a joint research project, researchers participating in the South Tianmen project were gathered from European countries, Lucia and other parts of the country.


    After all, this is a multinational joint research project, which needs to bring together researchers and technicians from various countries for collaborative research, even in the era of network development before the disaster.


    Such a large multinational joint scientific research project is bound to bring together researchers and relevant technicians from all countries.


    Even in order to build the "Luan bird" large space strategic aircraft platform, it is necessary to set up a new research site. After all, mankind has never made such a huge thing before, and naturally there is no plant that can accommodate such a large thing.


    The newly established research site, after comprehensive consideration of the situation of various countries, is still placed in the territory of the United States.


    The site selection is an originally sealed air force base in Yanguo. Because it was selected as a research site, the originally sealed base has become lively again.


    Researchers from various countries were sent here by land ships, planes and trains. Most of them only know that they need to participate in a research project, and they don''t even know the specific situation of the project and what they want to do.


    Peter is such a researcher who was expropriated by the state without knowing anything, and then loaded on a land ship and sent along with others.


    At first, Peter felt a little afraid and overwhelmed about his current situation, but after a few days on the land ship, he gradually calmed down his mind.


    After all, he has no ability to resist the expropriation of state institutions. Even if Belgium, his country, is only a small country in Europe, and it would be gone if it were not for the buffer zone between France and Germany, the strength of a country is still beyond the resistance of a small scientist.


    Moreover, after boarding the land ship, he found that in addition to himself, scientific researchers from other European countries were also loaded on the land ship, and his mind was more stable.


    It is obvious that all European countries have participated in this matter by pulling people from so many countries in Europe. They still use the land ships of Yanguo people, and the Yanguo people have also mixed it.


    In the current environment, it is a good thing for researchers like Peter to participate in large projects shared by both China and European countries.


    You should know that Belgium is just a small European country that can''t be any smaller. In today''s environment, the life of the whole country is not very easy, let alone unofficial researchers like Peter.


    If Chen Xin hadn''t joined one of the knights in Europe with his mechanical knowledge, and became the logistics maintenance technician of the knights, responsible for repairing all kinds of vehicles for them, I''m afraid Peter would either starve to death or be sent to the battlefield.


    In the final analysis, he is only a mechanical researcher who is a little famous in Belgium. He is not a famous scholar. Even if the country wants to preserve its scientific research strength, his name will not be on the list.


    In fact, before joining the knights, Peter had a very tight life.


    If he hadn''t been single all the time, fed alone and the whole family were not hungry, he had a good income before the disaster. He also made some transformation to his family when he was idle. He could earn a living in this ordinary era of the end of the world by relying on some small hands. I''m afraid he would have starved to death.


    After joining the knights, although he had enough to eat and drink, his life was not as good as expected.


    After all, the Knights are supported by free cities. If the situation in the city is bad, so is the Knights. In addition, Belgium is a small country, and the public security situation is actually good. The Knights do not have many tasks, so they can''t exchange more equipment for their achievements. Naturally, their life will be ordinary.


    So for Peter, to be able to participate in such a large-scale project with high confidentiality, let alone his treatment in the future.


    This can be seen only from the meals that can be eaten every day on land ships.


    Even if the land ships only provide emergency food and dehydrated vegetables, they are much more delicious than synthetic protein blocks. At least this is normal food, not industrial raw materials.


    Although synthetic protein blocks have solved the problem of declining food production in European countries due to war, to be honest, even after seasoning, the taste and taste of synthetic protein blocks are really not flattering.


    After years of eating decent food again, Peter really finished his meal with tears, and he was not the only one who cried.


    Although the whole of Europe is much better because of Chen Xin''s combing in that year, and European countries have benefited a lot from various construction projects of Yanguo''s European aid fleet and the opening of mines everywhere, with the bottomless hole of European defense line, the living standard of people in European countries is still at a very low standard.


    This also led to the fact that when there were new people on the land ship, the first people watched them in the canteen. Their tears because they ate decent food became one of the few entertainment items for Peter and others on the land ship.


    After all, it''s fun to watch others cry because they eat decent food.


    But their joy did not last long. When all the cabins on the land ship were occupied, the land ship turned to the East and flew back to the burning country.


    "My God! Is that the blue sky?! the sun rises!" as the land ship gradually approached Yanguo, the sky gradually became clear, and they came back in time. It was just when the sun rose, so Peter, who saw the sunrise, was stunned.


    As surprised as Peter, there were other people on the land ship. They could not help but squeeze into the cabin on the side where they could see the sun and put their heads close to the porthole in order to see the rising sun.


    "I never thought that the sunrise was so beautiful!" a researcher looked at the fiery red sun outside the window and sincerely praised it, saying everyone''s voice at the moment.


    For people who have never lost, they may not feel how valuable and important the sun rises as usual every day.


    But for those who have experienced darkness, the light that pierces the darkness is the most precious thing.


    These researchers recruited from European countries have the deepest experience when the sun shines on their faces.

 Chapter 839

    There was not only one land ship carrying the researchers. Peter and his land ship were landing slowly on the airport apron, and two other land ships were also landing.


    However, one of the other two land ships is obviously somewhat different in shape, looks more round, and has no tracks for ground travel. It is more like a spaceship than a land ship.


    In fact, this is indeed a spaceship. After removing the part of the land ship used for land travel, the spaceship used the spare hull space and load to install nuclear reactors and thrusters, making it a spaceship that can fly in the atmosphere.


    This is a spaceship that Chen Xin rebuilt after he made a spaceship for the space Department last time, but one is different from that spaceship, because although this one has the same engine and anti gravity generator, it has not been modified for space and can only fly in the atmosphere.


    Its size is only about two-thirds of that of a normal land ship, and its internal structure is very different from that of an ordinary land ship.


    Other land-based ships, warships or cargo ships are not specially designed to carry personnel, nor do they have too many requirements for internal comfort. Everything is designed on the premise of practicality, and the highlight is simplicity.


    But this ship is different. It is more close to the concept of a business ship.


    The interior mainly focuses on the personnel cabin and emphasizes the comfort of the cabin. Therefore, Chen Xin specially went to the train manufacturer, consulted them about the design experience of the special train luxury compartment, and asked them to help design the interior decoration of the cabin to improve the living comfort of the whole spacecraft.


    The ship has also become a standard personnel transport ship for transporting important personnel. It is different from other land ships like trucks and commercial vehicles.


    This time, Chen Xin came to the research base on this spaceship, together with several domestic experts in related fields.


    These experts are different from those researchers who are transported by land ships like strong men. Although those researchers also have some abilities and fame, they are undoubtedly several grades worse in terms of ability and fame than these figures who can be said to be Taishan Beidou in their respective fields, and naturally there is a big gap in treatment.


    These experts can enjoy the shuttle of the newly built official ship, and those ordinary scientific researchers can only ride on land ships.


    After the official ship sent Chen Xin and several domestic experts, it still needs to go to Lucia and Europe to pick up several experts from their countries.


    Compared with those ordinary researchers who were recruited like catching strong men, it is obvious that these experts are the ones who can really play an important role in the whole South Tianmen project.


    After all, just like Edison''s famous saying, genius is one percent inspiration and 99 percent sweat. Of course, without that one percent inspiration, all the sweat in the world is just sweat!


    In terms of scientific research projects, those researchers with a large number belong to the 99% sweat. Although they can''t complete the research of the project without them, they also can''t achieve breakthrough without the experts who are 1% inspiration. No matter how many other researchers are.


    "Hey, Peter, do you see that spaceship over there? The people of Yanguo treat their own people very well! That ship looks much more imposing than the one we sit on." on the apron, another researcher who lives in the same cabin with Peter is shivering with cold, but still doesn''t forget to talk with Peter.


    They saw the airship on the apron, the airship''s more imposing and beautiful appearance than the land ship they sat on, and the ferry car that didn''t need to expose people to the cold at all.


    This obviously made the researcher feel unbalanced, and he was obviously dissatisfied with the differential treatment of Yanguo.


    But Peter shook his head and said to him: "The people who came down from that spaceship are the top experts of Yanguo in aviation, aerospace, materials and other fields. Although I haven''t seen that young man, you should know his name. His name is Chen Xin. At present, he is the most important comprehensive scientist in Yanguo. When he was in Europe, he completely reversed the current situation in Europe on his own, even if I was only in Belgium A small place and I have heard of his name. How can such a big man be treated like us! "


    "There are so many experts at this level at one time. What are Yanguo and other countries doing?" the researcher was obviously confused.


    They didn''t know anything when they were loaded on the land ship. They only knew that all countries were searching for more famous scientific researchers, and then shipped them here. It was said that they wanted to participate in a big project, but they didn''t tell them what they came for.


    Peter obviously didn''t know either, but judging from what he saw in front of him, he didn''t need to think much to come to the conclusion that this must be a major event.


    Although these scientific researchers sent by various countries are not as good as those real bosses, they are still small and famous in their respective countries. Before the disaster, they are at least professors in well-known universities. Therefore, although they do not have the treatment of those bosses, they can still enjoy good treatment in this base, at least better than before they came not a few.


    Peter and the researcher were assigned to the same double room because they were together.


    Because the base is reopened, the living environment is mainly dominated by movable plank houses. However, these plank houses are obviously not temporary plank houses, and the internal space is at least equivalent to the business hotel before the disaster.


    Peter was very satisfied with two single beds, two writing desks, and supporting bathroom and heating equipment.


    Especially the heating equipment, which makes Peter, who used to rely on the traditional heating method of fireplace for most of his time in Europe, sincerely thank the beauty of technology.


    After putting down their luggage and sorting out and packing up respectively, they are ready to go out together. They intend to get familiar with the environment first, and then find someone to understand the situation. At least they should find out what they want to do when so many of them are gathered here.


    However, after they went out, they soon met other people from the same land ship. Under the persuasion of the other party, they chose to act together and walked towards the canteen of the base.


    Obviously, eating is the first demand of human beings at any time.


    Especially after the experience on land ships, they obviously look forward to the food treatment that Yanguo can provide.

 Chapter 840

    The food provided by the base restaurant did not live up to the expectations of Peter and others. Fresh rice and vegetables were something they had not eaten for a long time. In particular, the base also provided fresh meat. Although the quantity was small, it also moved Peter and others who had not eaten meat for several years to tears again.


    If it hadn''t been for the last few meals on the land ship so that Peter and others wouldn''t look too ugly, I''m afraid their lunch would be very humiliating.


    However, even so, they wolfed down a meal, causing everyone to eat.


    However, everyone obviously has some unfinished business. If the stomach didn''t start to send a signal warning them that there would be problems if they ate again, I''m afraid they would be tempted to put something in their stomach.


    This also led to that when lunch was over, Peter and others had a big stomach and collapsed on the chair for a long time.


    "This is the fullest meal I have had since the disaster!" one of them seemed to slow down and adjust his sitting posture, which was filled with heartfelt emotion.


    "The people of Yanguo seem to be quite rich in materials. Have you noticed? They don''t limit the number of meals we eat at all, but they just ask us to eat and not waste!" another person seems to have been observing just now. He also eats less. At this time, he is talking about his discovery: "In other words, these people don''t care how much you eat!"


    Hearing what the two companions said, Peter couldn''t help joking: "if you can eat like this every day, I can do whatever the Chinese people want me to do, and I have no problem doing it!"


    "Ha ha! People in Yanguo don''t like your old ass!" everyone laughed when they heard Peter''s joke, but someone asked more concerned and curious: "but what kind of project do Yanguo people want to study? Speaking, everyone''s good direction is different?


    I''m electrical. I''ve made wing circuits for the A350 in Airbus before. What about you? Maybe we can infer what Yanguo people want to build from the direction we''re good at! "


    "I''m a mechanic and used to teach in the University." Peter also introduced his specialty.


    "Machinery? What''s the specific aspect? I''m also engaged in machinery, but I study mechanical dynamics. There was a research project before, but the project stopped after the disaster." another person also made an introduction and looked at Peter with a desire to communicate.


    After all, after so many years of disaster, no one can communicate in the professional field for a long time. Now he finally meets a person who can communicate, which obviously makes him eager to discuss their previous research with Peter.


    "I study the control of large machinery." Peter seems reluctant to mention the past. After all, he was also a scholar at the beginning, but now he has been reduced to repairing vehicles for the Knights and has become a repairman, which is a big difference.


    But Peter is not the only one with this idea, but some people prefer to recall the past rather than recognize the present.


    After a few people had an exchange, they found that the fields they involved included many industries such as machinery, aviation, electrical and metallurgy. Although they could not be said to have no intersection, it was impossible to infer the purpose of Yanguo to gather them from their respective expertise.


    After all, it is possible to build anything in these industries.


    While a group of people were discussing, a radio suddenly rang out in the whole base, which was broadcast in turn in many different languages to inform all staff participating in the project to attend the meeting in the afternoon.


    Hearing the broadcast notice, several people gave up and continued to guess. After all, what does Yanguo want them to do? A statement will certainly be given at the afternoon meeting.


    Instead of guessing for themselves, it''s better to wait for the meeting notice, so several people left the canteen, prepared to go back to their rooms for a rest, and then went to the meeting together in the afternoon.


    Peter and his companions went back to the room. After lying in bed for a while, they set out together and followed the crowd to a huge hangar for the meeting.


    Obviously, there were too many people participating in the meeting. Even the United States could not prepare a meeting room for so many people. It had to choose an hangar in the base as the meeting place.


    However, although it is the hangar, enough chairs are prepared to let everyone sit down for a meeting instead of standing.


    Peter and some people who came with him found a corner seat and sat down, chatting and waiting for the beginning of the meeting.


    Because of the previous notice, everyone received the information of the meeting, so soon the hangar was full.


    As the participants of the meeting came to Qi one after another, some important experts from Yanguo also appeared in the venue. In addition to them, there are some experts from other countries, all of whom are leaders in their respective industries.


    Soon, a meeting host from Yanguo announced the beginning of the meeting. After finishing his opening remarks, he directly projected a picture that could be seen by everyone in the hangar on the huge white cloth hanging in the hangar.


    The picture shows a rather huge aircraft with its parameters listed next to it.


    "My God! They actually want to make this kind of thing!" "are the people in Yanguo crazy? How can they make this kind of thing!"


    "With such a large volume and a takeoff weight of more than 100000 tons, what do they take to make it fly?"


    The huge "Luan bird" large space strategic aircraft platform in the picture almost instantly aroused heated discussion among everyone in the venue. Obviously, everyone was shocked and incredible by such a huge aircraft, but also felt impractical.


    The "Luan bird" large-scale Aerospace strategic carrier platform, whether it is the flight altitude, take-off weight, or the huge volume itself, is in the cognition of these people. The height that human science and technology can not reach at present, that is, it can not build such a large aircraft, nor can it fly.


    But obviously, Yanguo was not worried about these two issues. Chen Xin began to explain after the host calmed down the venue.


    As the general director of the project, it is natural for him to dispel the concerns and doubts of others on this occasion, and build up their confidence that they can make the research project.


    Of course, what Chen Xin used as an explanation is the land-based ships and land-based aircraft carriers that Yanguo has put into use.


    Seeing that the huge body of the land aircraft carrier could fly, the whispering voice sounded again in the meeting hall, but this time they obviously turned to discussing the possibility of building the "Luan bird".

 Chapter 841

    Peter soon got an introduction to the scientific research project that needed to mobilize many countries to participate.


    "Nantian gateproject?" Peter read out the name on the cover, raised his eyebrows, and made no comment on it.


    It is a tradition for Chinese people to use some classical names in these scientific research projects, which was known by many people before the disaster.


    Peter cares more about what he wants to do than the name.


    After opening the information, Peter carefully read the above introduction and finally had a concept of the "South Tianmen plan".


    This is a comprehensive air and space combat system building plan, and what Peter and others need to participate in is the part of developing a large air and space strategic carrier platform for this plan.


    Of course, they are not the main force of research. Those experts in all aspects sitting on the stage are the main force of research. Ordinary researchers like Peter probably start to fight these experts.


    Peter doesn''t care about this. He knows his own abilities very well. Even if he is responsible for such a large-scale project, he doesn''t have this ability. He will only make a mess of things.


    Looking through the information, Peter quickly saw the content related to himself.


    Although there are many participants in the whole project, even if only the people in this base are filled with an hangar, it is obvious that the organization ability of Yanguo is very excellent.


    When they were loaded on the land ship, Peter had completed the data statistics of these people and registered their specialties. After they were sent to the base, these data were quickly entered into the supercomputer of the base. Xiyao brought by Chen Xin analyzed and processed them and quickly completed the distribution of these people, They were assigned to their respective departments.


    In addition to the materials introduced, there is also an identity card for everyone. After registering the identity information, the identity card will display the corresponding information, including department, responsible position and responsibility.


    This is not something made by Chen Xin, but the product of a scientific research department in China. It is a simple but very practical information terminal.


    Although it is only a small LCD screen composed of a signal receiver and a simple chip, it can exchange information with Xiyao who has now taken over the whole base through the wireless network, upload the user login information, obtain new instructions from Xiyao and display them on the LCD screen.


    At the same time, this simple information terminal is still everyone''s access control card and meal card. You need to use it to pass various access control and eat in the canteen.


    The cost of such a small card sized information terminal is not high, and the difficulty of technical implementation is very low, which is almost the level of pagers in the 1980s and 1990s.


    However, such a simple thing saves a lot of organizational work, because everyone can clarify their identity and responsibilities through this small information terminal without relying on manpower to convey them one by one.


    After completing his identity registration, Peter was assigned to the "R & D Department of large variable cycle engine matrix control technology" to participate in the power control R & D of the planned large Aerospace strategic carrier platform.


    For such a large project, of course, it is impossible to cram everyone into one department. In fact, Peter knows that there are more than 20 such large technology R & D departments. Each R & D department is responsible for the R & D of a technology, and there are various project groups and research groups below the project group.


    For example, Peter was assigned to a research group to be responsible for the research and development of a small project among tens of thousands of small projects under thousands of sub projects of the whole project, and Peter was appointed as the leader of the research group when he was assigned his duties.


    Before the disaster, Peter was also responsible for some research projects. It was not difficult for him to be the leader of the research team.


    Through the information terminal as the identity card, he sent information to the people in his group and asked all the people in his group to gather in their office space first.


    This is Peter''s cleverness. After all, the meeting is over at this time. Everyone in the hangar is logging in and querying their assigned positions through the information terminal. If you stay in place and call the people of your department, I''m afraid you can''t call them up when it''s dark for dinner.


    Simply go to the office first and gather in a place where there are few people over there.


    Peter''s method obviously worked well. When he came to the research room assigned to them, two members of his team arrived first, and the others continued to arrive.


    After getting to know each other and getting familiar with the environment, we quickly adapted to the new environment and new work.


    Although there is no need to start work immediately today, it is obvious that Peter and his team have taken the lead in completing the preparations and can put into work.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    When Peter knew his team members, Chen Xin was in the computer room of the base and learned about the situation in the base through Xiyao.


    "At present, 15% of the research teams have completed the personnel convergence, of which 7.4% have gone to the office and are familiar with the environment, and the rest are still in the hangar." each information terminal has a locator, and Xiyao can control everyone''s position at any time: "Their efficiency is too low. It is expected that it will be around 22:30 p.m. before everyone can complete the grouping and get familiar with the venue."


    "It doesn''t matter. As long as they can get familiar with their new colleagues and new office space today, and with the success of some people, the rest will be faster and faster." Chen Xin doesn''t think that these people''s efficiency is very slow like Xiyao, nor that they will delay so late.


    After all, Xiyao only made a rough estimation based on the motion trajectories of these people without detailed analysis, so the calculated data is only an inaccurate theoretical value.


    It''s not that Xiyao''s performance is not good, nor that she doesn''t have enough calculation capacity. At this time, the research work of the South Tianmen plan has begun. Chen Xin is calculating some data of the project he is responsible for with the help of the huge computing power of Xiyao and the supercomputer in the base.


    These data are very complex, and the amount of computation required is also very large. In fact, not only the supercomputer in the base is involved in the operation. Chen Xin also said that some data were packaged and sent to the supercomputer in the scientific research center, and the operation was assisted by deputy Xiyao there.


    The project that requires two supercomputers for calculation is the "directional energy shield defense technology" personally responsible by Chen Xin.

 Chapter 842

    What do you need to build a large space strategic aircraft platform?


    If you list everything, I''m afraid the catalogue alone can write a book.


    However, generally speaking, it is mainly composed of hull structure, energy system, power system and internal circulation system, as well as weapon system and carrier aircraft takeoff and landing system used for combat.


    There are so many disciplines and technologies involved that even before the disaster, all countries on the blue star may not be able to meet it together.


    After all, there are too many technologies that have not been developed by human beings. Even if the forces of the world are gathered, they may not be able to complete the theoretical basis of all technologies within 50 years.


    If not for the existence of Chen Xin, who can help open plug-ins, with the existing scientific and technological level of mankind, it may take another 100 years to make it fly.


    Instead of gathering a large number of scientific researchers like this, we began to start the basic design of all components mentioned in the South Tianmen plan under the arrangement of Chen Xin.


    Of course, the most difficult thing to complete in the South Tianmen plan is the "Luan bird" large space strategic aircraft platform. After all, this thing is too big. Even with anti gravity technology, it is very difficult to build such a big thing.


    Therefore, most of the researchers who were called up were put into the projects related to "Luan bird".


    As for the two parts of "Xuannv" aerospace unmanned combat aircraft and unmanned tactical aircraft armour, the assigned manpower may not be as many as the manpower of various sub items under the "Luan bird" project.


    However, even so, Xuannv Aerospace unmanned combat aircraft and unmanned tactical aircraft armor were the first departments to come up with the initial design.


    After all, relatively speaking, both air and space unmanned fighters and unmanned tactical aircraft armour have a good foundation in Yanguo. Although various technologies can not be said to be very mature, it is no problem to meet the needs of initial design.


    Especially the unmanned tactical aircraft armor, although it can not be said to be too simple for Yanguo, it is not difficult.


    After all, compared with the Titan, heavy machine armor and power armor currently used in Yanguo, the problem to be solved is the problem of remote control and self-discipline control, plus the problem of how to realize orbital airborne.


    For Yanguo, perhaps the only problem is how to realize orbital airborne.


    Compared with the large-scale Aerospace strategic aircraft platform that still solves the basic theoretical problems and the unmanned tactical aircraft armor that can basically directly pull out a finished product, the aerospace unmanned fighter project is most in line with the high-level intention of various countries, so as to achieve the purpose of integrating the technologies of various countries through joint research projects.


    First of all, the space fighter itself is not something out of reach for mankind. In 2010, the Federation tried to fly a prototype, claiming that it can continue to work in space for 270 days.


    In addition, although there are certain difficulties and thresholds for the current blue star countries in terms of the relevant technologies of air and space fighters, if countries take out all the things at the bottom of the pressure box and are willing to pay the cost, there is still no problem in making a flying prototype.


    The English took out their own engine technology, the French were responsible for most of the precision parts of the aerospace aircraft, and the Germans contributed their own materials and formulas for making aircraft.


    Relying on these technologies contributed by various countries, combined with the UAV technology that Yanguo had been ahead of the world before the disaster, and the relevant technical data of suviah era aerospace aircraft archaeologized by lucians from the pile of old papers


    With the help of supercomputer, the technology verification machine of "Xuannv" space unmanned combat aircraft was soon built.


    "Is this the technology verification machine you spent on building a land ship?" Chen Xin looked at the dark, unpainted plane in front of him, stroked his chin and said with a trace of curiosity: "introduce it to me."


    Chen Xin didn''t care much about the high cost of this technical verification machine as the general person in charge of the project.


    After all, for this kind of technology research and development, the initial technology verification machine or prototype would have been very expensive.


    Not to mention that this is a technology verification machine, which is intended to maximize the technical advantages for verification, regardless of the cost.


    "The aircraft uses nuclear batteries as the main power source, with a maximum flight speed of Mach 25, and has the ability to take off from the ground and directly enter space. However, we mainly take off the fighter from an altitude of 413000 feet from the ground, and rarely use the aircraft to enter space by itself." a researcher introduced Chen Xin and added: "Because this aircraft mainly solves flight and control problems, we have not installed weapon systems on it, which may affect the flight speed of the aircraft."


    "This is not a problem. Basically, air and space fighters take off from the air and space strategic carrier platform. The combat field is also the atmosphere above the stratosphere and low earth orbit. The requirements for the maximum flight speed are not so strict. Moreover, when they enter outer space, the weight is meaningless." Chen Xin has nothing to do with the impact on the maximum flight speed of the aircraft. After all, he has entered outer space and got rid of the influence of the earth''s gravity. The extra weight of a mere weapon system is really not a problem.


    After listening to the scientific researchers explain the flight control system and various materials used by the aircraft, Chen Xin said to them: "if there is no problem with the aircraft, we will arrange a test flight as soon as possible and strive to finalize the design of the prototype as soon as possible. However, here I want to make a request to you and reserve space for me to install shield equipment on the aircraft."


    "Shield equipment? Do fighters also need energy shields?" the researchers asked curiously when they heard Chen Xin''s words.


    Chen Xin nodded, confirmed the other party''s guess, and explained: "The installation of energy shield is mainly to improve the survivability of the aircraft in the space environment. After all, the test of the aircraft in the space environment is far more severe than that in the atmospheric environment. In case of any space garbage or fine cosmic dust, it is better to install an energy shield to resist rather than rely on the fuselage materials."


    "I see. We''ll leave some space when designing the prototype." the researcher nodded to understand.


    Chen Xin talked with the researchers about the research and development and flight test of the aircraft, and then turned and left the hangar where the technology verification aircraft was parked.

 Chapter 843

    The development of the large-scale space strategic carrier platform has not encountered any problems. After Chen Xin helped provide a set of artificial intelligence templates, the unmanned tactical aircraft armour quickly manufactured a prototype and began to carry out practical testing.


    Although the problem of orbital airborne has not been solved, the combat test of the mecha itself has no problem.


    As for the problem of airborne, it can be solved by hanging an airborne backpack.


    The whole Nantianmen plan, it can be said that all projects are still progressing smoothly, which makes Chen Xin, the general director of the project, feel relieved.


    After all, he was responsible for such a large project for the first time, which put him under considerable pressure.


    Although it is said that there is a system upgrade as the last card that can be used to reveal the bottom, and there is no fear that the project will fail, in case of any problems or mistakes, Chen Xin and the country still don''t want to see and can''t afford it.


    The investment of this project has reached the limit that the country can bear at present, and even the contribution of European countries and Lucia.


    Although it can not be said that all countries have done their best, at least this time, countries are really sincere cooperation, and there is no stinginess in the investment of resources and technology.


    And this also made him more aware of his great mission and how heavy the burden on his shoulders.


    Now all projects are progressing smoothly, which makes Chen Xin feel a little easier.


    "Ah Xin, how are you recently? Are you tired from your work?" the voice of mother''s concern came from the open communication equipment.


    "Fortunately, at present, the project is progressing smoothly and there is nothing tired." Chen Xin feels the concern of his parents and feels a lot of warmth in his heart. After all, thousands of miles apart, who will care about you so much except his parents and family?


    After a brief chat and caring about his parents'' health, Chen Xin hung up the phone.


    "Xiyao, how is the construction of the new urban area in the new town?" after the call with his parents, Chen Xin opened the intelligent terminal and asked Xiyao about the situation in the new town.


    Although Chen Xin is now in the military base of Xinjiang Province because he is responsible for the South Tianmen plan, he can still contact the new town through Xiyao to understand the various conditions of the new town and the construction progress of the new city.


    Although Chen Xin is not responsible for the construction of the new urban area, and he participated in the re formulation of the design scheme, he is still very concerned about it.


    "At present, the dome of the new city has been installed, and all buildings have been capped through 3D printing technology. The final internal decoration is under way. According to the data transmitted from the No. 1 auxiliary body of the new city, it will take about a week for the new city to be delivered." Xiyao showed the data collected by his own auxiliary body in the new city in front of Chen Xin.


    Because the body of Xiyao was brought to the military base in Xinjiang Province by Chen Xin, the vice body of Xiyao remained in the new city and the scientific research center. In order to distinguish, according to the order, the second vice body of the scientific research center and the first vice body of the new city.


    There is no difference between the two parabodies and Xiyao''s ontology in performance. More accurately, they are exactly the same as Xiyao, but copy the data in the past.


    However, Chen Xin has made some intelligent restrictions on the vice body, that is, it limits the intelligent growth of the vice body.


    At present, the security of artificial intelligence has not been fully verified, and no one dares to allow the unlimited growth of artificial intelligence. Therefore, except Xiyao''s ontology, all other artificial intelligence have set the upper limit of growth to prevent it from growing into a real artificial intelligence, that is, digital life.


    As for Xiyao itself, it is out of the need to co-ordinate other vice bodies and artificial intelligence research that Xiyao has released some of the upper limits of growth.


    But even Xiyao''s ontology has a growth limit and is written into the underlying code.


    Looking at the data displayed by Xiyao and processing several documents that need to be signed and confirmed by him through remote transmission, Chen Xin is busy with everything today.


    He stood up and looked out of the window. At this time, it was dark, and a bright moon was hanging high in the sky.


    Because Xinjiang province is already the border of Yanguo, it is actually the outermost part of the clear sky of Yanguo, and there is still a lot of dust floating in the sky.


    This also makes the moon in the sky seem to be covered with a layer of gauze, which looks hazy, but adds a special beauty.


    "The bright moon rises from the Tianshan Mountains and the vast sea of clouds." looking at the bright moon outside the window, Chen Xin remembered these two poems for some reason.


    At this time, he seems to be particularly able to resonate with ancient poets and feel the emotions that the ancients wanted to convey through poetry.


    After all, at this moment, Chen Xin also goes to the frontier for the sake of his country and misses his parents and family in his hometown.


    But in ancient times, people came to defend the border for the country, lower than the invasion of foreign enemies, while now Chen Xin comes to the border to study new scientific research projects for the country.


    Although the purpose is different, the feelings of home and country can also resonate.


    "When people in ancient times looked up to the moon like me, I''m afraid they would never imagine that blue star would become like this one day?" Chen Xin couldn''t help feeling that the ancient poet who wrote magnificent poems would be stunned to see today''s scene.


    After all, the sky is covered by dust, and the earth is plunged into eternal night. For the ancients, such terrible things can only be seen in fairy tales.


    However, for the ancients, it is no different from the disaster of the collapse of the sky and the need to refine stones to mend the sky, which has been gradually overcome in the hands of modern people. This has to be said to be a great miracle created by mankind.


    "Sorry, academician, I can''t understand what you said." Xiyao on the intelligent terminal was not closed, but although she heard Chen Xin''s words, she couldn''t understand the meaning of the words.


    Her language recognition module recognizes what Chen Xin said, but she is only an intelligent program limited by the upper limit of intelligent growth. She can''t understand the feelings and feelings contained in Chen Xin''s words like a real human.


    "It doesn''t matter if you can''t understand. One day you will understand." Chen Xin didn''t mind Xiyao''s incomprehension, but smiled at her: "one day, you will understand what I said today, and then you will understand."


    Chen Xin did not continue to explain. Instead, he found a cup in the room, poured himself a glass of wine, sat in front of the window, looked at the hazy moon, raised his glass and drank with the moon in imitation of the ancients.

 Chapter 844

    The military base used as the research site of the South Tianmen project is an air force base. Naturally, it also has a runway.


    However, this runway has not been used for a long time. Since the air base was sealed before the disaster, there have been no aircraft taking off and landing on this runway for several years.


    When Chen Xin and his crew arrived by land ship, they just landed on the tarmac full of snow.


    It''s not that they don''t remove the snow, but the snow more than ten meters thick. It''s really a huge project to remove it, and the snow is very thick. Instead of cleaning the snow, it''s better to open a roller to compact the snow and use it directly on the ground.


    The only problem may be that the road will slip after the snow is compacted, but even if the snow is cleared, the ground is as easy to freeze and slip in such a cold day.


    Therefore, in order to solve the runway problem of aerospace aircraft test flight, the staff of the base spent three days to level the snow covered runway, so that it can at least meet the standard of Field Airport and can be used for aerospace aircraft test flight.


    "Is there no problem with the runway? No, the runway melts directly as soon as the aircraft engine is ignited?" Chen Xin''s worry is not groundless. After all, the technical verification aircraft of the test flight aerospace aircraft still uses the traditional jet engine, not the NVN induction force field engine and kd-64bv variable cycle engine set on the Xuannv Aerospace UAV in the South Tianmen plan.


    The so-called NVN induction force field engine is a radiation propulsion engine, which uses the products of the giant change reactor as the medium for propulsion. This propulsion mode is still too early for human beings, and science and technology have not developed to this point.


    Therefore, the traditional engine technology that has been mature is adopted by the overhead aircraft. Relying on the advanced technology provided by various countries, the aircraft can meet the design requirements.


    However, this also brings a problem, that is, when the aircraft engine starts, the temperature of the tail flame can reach a high temperature of thousands of degrees. If the snow melts, it will evaporate in an instant.


    The researcher on one side didn''t worry much about it and replied to Chen Xin: "academician Chen, please rest assured that we have made detailed calculations and there will be no problem."


    With that, he introduced the situation of the aerospace plane to Chen Xin in detail, explaining that even if the snow on the runway was evaporated by the tail flame of the aerospace plane, it would not affect the test flight of the aerospace plane.


    Chen Xin nodded after listening to the explanation. He also knew that since these researchers were able to formulate such a flight test plan, it was obvious that they had made detailed calculations in all aspects and decided to do so only after they were sure there was no problem.


    But he was still a little worried, so he asked more.


    Moreover, Chen Xin not only asked, but also sent the researcher''s explanation to Xiyao and asked her to help with derivation and calculation.


    Although he had asked Xiyao to calculate these data before the test flight, when the project team submitted the test flight application plan to Chen Xin, he still didn''t trust Xiyao to calculate it again. After confirming that there was really no problem, he agreed to let the overhead plane take off.


    As Chen Xin''s order was conveyed, the aerospace plane on the runway began various pre flight inspections and started the engine.


    Chen Xin looked at the plane on the runway with his telescope. At this time, its surface had been sprayed with a layer of black protective paint, which was very inconspicuous.


    However, the fully enclosed nose, which is different from the traditional aircraft glass cockpit, still illustrates the essence of this aerial UAV.


    "I remember that Xuannv''s design adopts two operation modes: forward swept wing and manned unmanned?" watching the test flight of the aerospace aircraft enter the reserved position on the runway, Chen Xin suddenly asked the researcher aside.


    According to the original design of the South Tianmen plan, the Xuannv Aerospace UAV adopts neural induction control. The pilot directly controls the aircraft through the helmet, so it does not need the glass cockpit of the traditional aircraft.


    In the unmanned mode, a neuron computer with bionic human brain will be installed in the cockpit to control the flight and mission of the aircraft.


    Of course, there is no problem with this design. In addition to the fact that current technology can''t do these things at all, there are really no shortcomings.


    Even the wing design of the aircraft was specially analyzed at that time. Although it can not be said to be reasonable or superior in performance, at least this structure can really fly.


    Therefore, after the whole Nantianmen plan was taken out, the original sci-fi level settings and requirements only made some simple modifications or lowered standards to make it conform to the reality and the current scientific and technological level. In addition, no more adjustments were made.


    But on the aerospace plane, what Chen Xin saw was that the technical verification plane for the test flight abandoned most of the original design of Xuannv Aerospace unmanned combat aircraft.


    Rather than saying that this technology verification aircraft is the product of the realization of Xuannv Aerospace unmanned combat aircraft, it is just an aircraft redesigned according to the idea of Xuannv Aerospace unmanned combat aircraft.


    Obviously, the researcher on the side also understood this problem. Facing Chen Xin''s inquiry, he explained to him: "In addition to our technology, the original design of Xuannv fighter also has some problems in its own layout. For example, its forward swept wing design and the front wing of rhombic connecting wing design will have a certain conflict, which will greatly affect the elevation performance of the aircraft. Therefore, we modified the aerodynamic layout and redesigned the aircraft.


    At present, academician, the technology verification machine you see adopts a pneumatic shape originally designed by Lucia for su-47 golden carving. However, the whole su-47 project has not been put into production, so this design has not been really produced, but has been tested in wind tunnel.


    The South Tianmen project needs this, so Lucia took out this design, coupled with other finished technologies provided by various countries, so we have the current technology verification machine. "


    Chen Xin was not surprised to hear the researcher say so. When he went to inspect, he really didn''t pay much attention to the shape of the aircraft. After all, he had a lot of things at that time, so the specific responsibility of each project was handed over to the project leader.


    He is only responsible for dealing with the overall situation, so specific details like this can only be seen when the plane flies.


    In particular, Chen Xin doesn''t know much about aircraft. If there was not a conceptual design drawing of Xuannv Aerospace UAV in the data in front of him, he might not be able to find this difference, which looks different from the technical verification aircraft in front of him.


    While Chen Xin and the researchers were talking about this, the technology verification aircraft on the runway also completed all the preparations before takeoff, and the engine emitted a long tail flame, pushing it into the blue sky.

    The test flight of the new space plane was quite successful. Although it did not really break through the atmosphere into space, it still flew to an altitude of 30000 meters with the powerful thrust of the engine, and always maintained the ultra-high speed of Mach 7.


    This is very incredible for an aircraft. After all, under normal circumstances, the flight speed of supersonic fighters is below Mach 3.


    Although we can build an aircraft that can accelerate to Mach 10, this kind of aircraft is not a fighter, which requires high mobility.


    As for the reason, it is not that there are any technical obstacles, but that when maneuvering at high speed, the pilot can not bear the ultra-high G force brought by large-scale maneuvering at hypersonic speed.


    Although it is said that astronauts can withstand greater G force with the anti-G design of space suits after strict training, the problem is that it is impossible for every fighter pilot to reach the level of astronauts, and it is impossible to give every fighter pilot a space suit.


    Therefore, in order to protect pilots, the flight speed of fighters is limited.


    In fact, in the South Tianmen project, the original Xuannv Aerospace unmanned fighter also adopted the pilot protection design because of the manned driving mode. The flight speed in the atmosphere was limited to about Mach 5. Only after leaving the atmosphere can it reach the high speed of Mach 25 of the speed of the second universe.


    When there is no one at all, this consideration can be omitted. After all, whether the aircraft itself can withstand such a large G force is a matter of materials, and the upper limit that metal can withstand is obviously much higher than that of human beings.


    Therefore, even at Mach 7 hypersonic speed, this test flight aerospace aircraft technology verification aircraft can still carry out various maneuvers and has a good performance and performance.


    However, even so, there are still many problems with this technology verification machine. After all, it is a piece of things pieced together by various technologies. Although there is no problem for the aircraft to fly, there are still some coordination problems among various technologies.


    It is precisely because of these small problems that the overhead plane did not complete all the flight test projects.


    After all, according to the design, the technical verification aircraft for the test flight is to try to fly to an altitude of 40000 meters for a hypersonic cruise flight of Mach 10, but now it has only reached an altitude of 30000 meters and a speed of Mach 7.


    This obviously does not meet the expected requirements.


    Therefore, after the plane returned, it was immediately taken back to the hangar by the aerospace aircraft project team and immediately started inspection and adjustment.


    Chen Xin did not intervene in the space plane, although if he did, let alone the space plane designed now, even if he really built the Xuannv fighter in the conceptual state of the South Tianmen plan, it would be nothing more than a matter of thinking for Chen Xin.


    But this obviously conflicts with the joint research itself. After all, the purpose of all countries is to integrate the technology of all countries through joint research, not to say that they lack this overhead fighter.


    And more importantly, only by taking this whole R & D route once can we accumulate enough experience.


    Not to say that the plane was made, I only know how to make it, but I don''t know why.


    This is also the blood and tears experienced by Yanguo in that year, because the industrial foundation was weak in the early days of the founding of the people''s Republic of China, and many things were built with the assistance of suvia in that year. Later, the relationship with suvia deteriorated, and the technical support for many things was cut off, so he had to focus on R & D himself. He suffered a lot of losses and lagged behind others.


    It was not until a few years before the disaster that the overall foundation of the country was established and the accumulation of various technologies reached the threshold that it caught up with others.


    Therefore, technology research and development is still very important. It does not mean that Chen Xin can solve the problem by making a finished product through system upgrading and allowing them to conduct reverse research.


    Although Chen Xin can build Xuannv fighters through system upgrading, no researchers have completed all the R & D routes step by step. Even if they can reverse crack all the technologies on Xuannv fighters, the country can only obtain these technologies. To really use them in practice, we still have to go through the route of product R & D again.


    If there are ready-made products for technical upgrading, it doesn''t matter. As long as there is no too fault in the upgrading, it can provide ideas for researchers and reduce their many exploration and detours.


    However, a product made from scratch can''t do this. In particular, the technology on the Xuannv fighter is full of black technology, and the fault between it and the technology now mastered by mankind is too obvious.


    Human cognition of these technologies is still in the stage of theory and concept. Even if we really have these technologies, it is still not easy to master them.


    After all, a technology does not mean that it is OK to have it. It also needs to be thoroughly studied, master the principle and be able to apply it in practice. This is the real mastery of a technology.


    Moreover, scientific and technological development has its context and style, which can be seen from the strong suvian style of military equipment in the early days of Yanguo. Even today, Yanguo''s scientific and Technological Development and military equipment line have gone out of its own style, we can still see the shadow of suvian technology in those years.


    This is the so-called technology system. After all, the style of suvia technology was obviously different from that of the Federation.


    The technology between the two cannot be said to be diametrically opposed, but it took many years of time and experience for Chinese researchers to integrate the two.


    This is the same generation of science and technology at the same level. If we come to a technology that has been ahead for decades, it can not be absorbed in a short time.


    This is like the power armor, Titan and other equipment currently used by Yanguo. Although Chen Xin made these things through upgrading, the relevant technologies have been reverse studied all the time.


    Many researchers in China are groping at the same time. As for what problems and how to improve, they are all black in their eyes.


    We can only draw the gourd according to what Chen Xin made, and send it to the battlefield for actual combat. If we encounter problems in actual combat, we can make minor repairs according to the feedback.


    It is still difficult to understand the technology and design a similar product by yourself.


    Otherwise, the power armor, exoskeleton, heavy machine armor and Titan used by Yanguo are all made by Chen Xin.


    This is also what a senior leader in charge of science and technology talked about before Chen xinlai.


    Although the country really needs these things made by Chen Xin and appreciates his contribution to the country, the development of science and technology can not be so encouraging.

    The development of science and technology needs to be gradual, and the breakthrough of scientific research projects needs to be accumulated, but this can only be aimed at those already basic scientific research projects.


    Only when there is basic accumulation can we proceed step by step on the basis.


    If it is a scientific research project without even the most basic basic accumulation, it is completely blind. We need to create a road from scratch.


    Under such circumstances, even if Chen Xin doesn''t want to encourage others, the state also hopes to accumulate more R & D experience, but Chen Xin can only make things first and then reverse crack them.


    Energy shield is obviously such a scientific research project.


    For human science and technology, the theoretical basis of energy shield is not available, but there are some possible or impossible assumptions in various science fiction works.


    Among these assumptions, the electromagnetic force field is more reliable or possible.


    In fact, each of us is in a huge energy shield - the planet''s magnetic field.


    The sun is not as amiable as expected. While providing us with light and heat, it will unkindly emit a large flow of high-speed charged particles to us.


    Without the protection of a strong magnetic field, the atmosphere on which we live will be stripped away, and there will be no life on the blue star.


    However, not all substances will be affected by electromagnetic force, so no matter how strong the electromagnetic force can "ignore all attacks", so if you want to turn the electromagnetic force field into a usable energy shield, you must add other things to the electromagnetic force field.


    As we all know, charged particles will be affected by the magnetic field. A strong magnetic field can also make charged particles move around themselves.


    In this case, if the number of charged particles moving around the magnetic field is large enough and the speed is fast enough, a barrier can be formed, and then the barrier can be shaped into any shape by the method of magnetic field superposition.


    Theoretically, such an energy shield can resist all attacks based on electromagnetic principles.


    According to the relativistic kinetic energy formula, when the speed of an object is infinitely close to the speed of light, its own kinetic energy is also infinitely increasing.


    According to this principle, the magnetic field can be used to accelerate charged particles to a very high speed, so that each particle can carry very high kinetic energy.


    When an attacking entity contacts the energy shield, a large number of high-speed charged particles will pour their kinetic energy on it, causing it to disintegrate and explode instantly.


    The fragments produced by the explosion will be blocked outside the shield by dense high-energy particles, and part of the energy released by the explosion will be absorbed by these particles and re transformed into its own kinetic energy, and the other part will be dissipated in the surrounding space.


    However, from the law of energy conservation, it is obvious that it takes a lot of energy to accelerate charged particles to a very high speed and carry a very high kinetic energy.


    Therefore, two key factors for manufacturing energy shield can be deduced, one is powerful energy, and the other is efficient and mature magnetic restraint technology.


    The charged particles are bound into shields by magnetic confinement technology, and then driven by electromagnetic field to move at high speed within the range of magnetic field confinement. Theoretically, this is the situation of energy shield that can be realized by human technology.


    The most critical two points, powerful energy and magnetic confinement technology, have actually been solved in the small fusion reactor realized by Chen Xin.


    However, the technical accumulation on these two issues is not deep enough. After all, researchers have not completely analyzed the small fusion reactor manufactured by Chen Xin, and even a giant change reaction power station has not been completed. It is obviously too early to go beyond these theoretical construction and directly start building energy shield.


    With the current science and technology of mankind, in addition to the technical bonus provided by Chen Xin, there is still a long way to go to create a sufficiently stable magnetic restraint device.


    Therefore, for the "directional energy shield defense technology" personally responsible by Chen Xin, he is still the only one who uses system upgrade to make finished products, and then hand them over to others for reverse cracking and theoretical construction.


    However, fortunately, due to the reverse research on small fusion reactors in China, some good results have been achieved in this area. After Chen Xin built a very simple energy shield generator, they can quickly find out the context and find the direction to start.


    Unlike some experts from other countries, looking at the energy shield generator rubbed out by Chen Xin, the face is full of mice pulling Turtles - it feels like there is no way to start.


    "Academician, I don''t think the shield generator can be activated all the time. We should adopt the design of reactive shield. The shield will start and activate only when something hits. Under normal flight conditions, I don''t think it''s necessary to operate the shield at full power, which is too energy-consuming." a researcher proposed to Chen Xin.


    Chen Xin nodded and said definitely, "good suggestion. It''s really unnecessary to keep the shield on all the time. We can connect the shield with the radar. When the radar starts to alarm, the shield starts to warm up, which can effectively save energy.


    In addition, we can also install high-density energy storage devices for the shield to store energy at ordinary times. When it is necessary to activate the shield, we can release energy from these high-density capacitors to drive the shield or reinforce the shield to resist high-intensity attacks. "


    As a former Internet writer, Chen Xin belongs to people with many brain holes. In addition, he has played too many science fiction games, including some very hard core games.


    As a very common science fiction setting, energy shield is naturally reflected in the game, and many forms can be used as a reference.


    "High density high-capacity capacitor? This is really OK! Store the energy at ordinary times and release the energy when the shield is activated, so that the instantaneous strength of the shield can be greatly improved, so that we can use low-power reactors or nuclear batteries to charge high-power shields!" a researcher obviously understood the benefits of this, Soon loudly agreed with Chen Xin''s proposal.


    However, there is no ready-made finished product for high-density high-capacity capacitors. It is obvious that the electric energy storage devices developed by human beings do not have the capacity to meet the energy consumption demand of energy shield.


    After some discussion with the researchers, Chen Xin can only add a research sub item of high-density and high-capacity capacitance to the research project.


    Fortunately, Chen Xin himself is the general person in charge. He can make a decision to add a research project without having to write a report for approval. Therefore, the project team was quickly established and put into operation.

    The runway is still the same as the test flight, but the test flight is different from the last one.


    Chen Xin has done a good job on the current aerospace plane. Although it has not been greatly changed, it is obvious that some problems exposed during the last test flight have been adjusted in this upgrade, and the shield device has been installed.


    This test flight, in addition to further testing the ultimate performance of the aerospace aircraft, is to test the shield device to test whether the shield device can operate normally at an altitude of 40000 meters.


    Because it has flown once, this takeoff is not as nervous as last time.


    "Academician Chen, what do you think of the test flight?" a scientific researcher from Europe asked Chen Xin in English.


    These scientific researchers from Europe have also been familiar with the working environment of Yanguo during this period, and have more contact with Chen Xin, the general person in charge, and become familiar with him gradually.


    While waiting for the space plane to complete the take-off inspection, I couldn''t help chatting with Chen Xin.


    "This test flight? I don''t have any opinion. The plane has flown once. There is no problem in all aspects of design. Theoretically, it can meet the design requirements. I don''t think there will be any problems in this test flight, unless there is an accident." facing this problem, Chen Xin didn''t say much, but just showed his confidence in this test flight.


    In fact, the same is true. After all, the overhead plane has flown once before and has been optimized by him with the system. There is no possibility of problems in terms of performance or quality.


    Although there is still the possibility of accidents, in theory, the test flight is safe.


    Hearing Chen Xin''s words, the European researcher raised his eyebrows and was obviously surprised by Chen Xin''s confidence in the test flight.


    But he didn''t say anything more, just nodded and said, "I hope God bless everything as smoothly as academician Chen said."


    "This is in China, you have to say God bless." Chen Xin joked, but he didn''t make fun of other people''s beliefs.


    Although this apocalyptic disaster has caused great suffering to the whole world and seriously affected the religions of all countries in the world, there are still a large number of devout believers who are more determined in this case.


    They believe that this disaster is only a test given by the gods to mankind. Mankind needs to abandon bad habits and sins, purify themselves and regain the care of the gods.


    Chen Xin has always scoffed at this statement. When he was in Europe, he had a conflict with religious groups in a city, which ended in violent repression.


    But he has great respect for people who really believe in piety and are willing to be strict with themselves and not force others to believe.


    The foreign researcher in front of us is obviously not a pious person. The so-called God bless is just a mantra developed over the years.


    So in the face of Chen Xin''s ridicule, he just shrugged and made an indifferent expression.


    While they chatted, the aerospace plane also completed the preparations before the test flight, entered the runway and soared to the sky with the roar of the engine.


    Watching the SkyPlane climb, Chen Xin suddenly asked the researchers aside, "do you have any ideas about the weapons of the SkyPlane?"


    "At present, there is no good idea. I''m afraid it doesn''t make much sense to install missiles on aerospace aircraft. After all, the flight speed of aerospace aircraft can reach Mach 10, which is faster than that of many missiles." the researchers shook their heads. Obviously, there is no good answer to Chen Xin''s question.


    In fact, the same is true. Even if the ultra-high speed missile df-17 currently equipped by Yanguo has a maximum flight speed of Mach 10, it is still a ballistic missile, which is not the same as the missile equipped on ordinary fighters.


    Therefore, the project team has a headache about what weapons the aerospace plane should be equipped with.


    If we want to develop missiles for use in hypersonic environment, it is undoubtedly a new project, which will increase the investment cost of air and space fighters.


    However, it is obviously impossible to say or not to do. After all, aerospace aircraft are used for war. It is impossible to say that aircraft are made without weapons and can only be used as high-speed reconnaissance aircraft.


    But it is obviously not easy to develop a hypersonic air-to-air missile or air-to-ground missile that did not exist before.


    First of all, the engine of the missile is a big problem. After all, not all missiles can reach a flight speed of more than Mach 10.


    Df-17 is a ballistic missile. Relevant design experience cannot be directly applied to air-to-air missiles or air-to-ground missiles.


    "How about laser weapons?" Chen Xin put forward an idea.


    In the ultra-high speed environment, the laser is indeed much more ideal than the missile. After all, no matter how fast the aircraft is, it is not as fast as the speed of light.


    "Laser weapons are indeed feasible, but under the current technical conditions, high-power laser weapons will have large optical lenses, which will be easily damaged in the ultra-high speed environment. If this problem can not be solved, the laser weapons can not be used in the ultra-high speed aircraft." the researchers nodded and agreed with Chen Xin''s idea, but also pointed out the problem.


    At the current scientific and technological level of mankind, the most practical laser weapons are those made by Chen Xin''s scientific research center. However, even if those laser weapons that have been tested in actual combat want to be applied to ultra-high speed air and space fighters, there are still many technical difficulties to be overcome.


    Without Chen Xin''s intervention, it is obvious that mankind can not make such a scientific and technological breakthrough in a short time.


    Chen Xin also nodded clearly. He naturally knows this. After all, he has also participated in the R & D and manufacturing of laser weapons.


    But difficulties are difficulties. If there is no good solution to the problem, we should do it, whether it is laser weapons, hypersonic air-to-air missiles and air-to-air missiles.


    However, at this time, another scientific researcher on the side suddenly said, "I don''t know whether the high-energy particle beam weapon is feasible? Since we can build a magnetic beam device to restrain the high-energy charged particles into a shield, can we also launch it into a weapon?"


    "High energy particle beam? Do you mean to accelerate charged particles with a magnetic field and then use the kinetic energy carried by the particle beam to cause damage?" Chen Xin couldn''t help but feel bright at the suggestion of the scientific researcher.


    This is indeed a very feasible idea. After all, the energy shield has been built. The technical principle used between the two is the same, just changing the application mode of electromagnetic field.

    "At present, the flight altitude of the aerospace-1 test aircraft is 40000 meters, and the flight speed is Mach 9.5. It has reached the scheduled flight altitude. Please indicate whether to start the shield device according to the original plan for Shield operation test?" the pilot responsible for operating the aerospace aircraft on the ground asked loudly for instructions when he saw that the aircraft had reached the flight altitude scheduled for the test.


    According to the scheduled test plan, the test flight of the aerospace aircraft is to test the shield system.


    In fact, the shield system has been turned on since the space plane took off, and a series of tests have been carried out during the climb.


    Now we are going to test whether the shield system can start normally and smoothly in the hypersonic flight environment.


    Although in theory, the shield system will not have any problems, even the fighter with mature technology will have various faults such as engine shutdown, aircraft stall and power failure in the sky. In case the shield equipment is affected by the fault, whether it can be started and restarted smoothly has become an important matter related to the life and death of the aircraft.


    Moreover, even if there is no fault, it is still a very important thing whether the shield generator can be restarted manually in the high-altitude and high-speed environment.


    Therefore, the test of shield equipment switching on and off in high-altitude and high-speed environment is added to the test plan.


    At this time, the pilot asked for instructions, and the project leader in charge of command approved it according to the test plan. The pilot who received the instructions immediately operated according to the operation process.


    Through the camera on the aerospace plane, Chen Xin and others can clearly see through the display screen of the tower. With the pilot''s operation, a light blue barrier is quickly formed around the aircraft fuselage, but the light soon fades down, as if it was just an illusion.


    However, both the sudden increase in energy consumption of the aerospace aircraft and the display of various instruments on the aerospace aircraft prove that the shield system has been successfully restarted and in good condition.


    The crowd couldn''t help cheering. The fact that the aerospace plane could pass various tests in the high-altitude and high-speed environment not only marks an important achievement of the South Tianmen project, but also marks that mankind has possessed the energy shield technology from now on.


    Seeing that the shield equipment was running well, everyone congratulated Chen Xin.


    He is the general director of the whole plan and the general director of the shield project. Undoubtedly, the smooth research and development of shield technology is due to him.


    But Chen Xin was very insipid. He just smiled politely. After receiving the congratulations from everyone, he ordered the pilot to continue other tests.


    However, the main tests have been completed, and the rest are only the basic projects of performance tests. Although they must be completed, they will not affect the overall situation.


    Moreover, due to the lack of weapons used in this high-altitude and high-speed environment, it is impossible to conduct actual combat tests on shield equipment. Therefore, after completing all the test items, Chen Xin ordered the aerospace plane to return.


    "Can the air defense weapons we have now pose a threat to aerospace aircraft?" thinking of this question, Chen Xin asked an air force officer nearby.


    The South Tianmen project was originally developed by the air force, and the air force also participated in various projects. Naturally, air force officers were also present during the test flight of aerospace aircraft.


    Hearing Chen Xin''s question, the air force officer shook his head: "if the aerospace plane maintains hypersonic flight speed, there is no way to shoot it down in terms of the performance of air defense weapons we currently have. The speed is too fast. Even if the radar can be locked, the missile can''t catch up."


    Hypersonic missile is one of the most advanced missiles in the world before the disaster. It is very difficult to intercept it with the existing human air defense weapon system.


    After replacing hypersonic missiles with more flexible hypersonic aircraft, the interception difficulty is undoubtedly greatly enhanced.


    Because the flight speed of hypersonic aircraft is too fast, when maneuvering in the air, it will bring great tracking overload pressure to the missiles to intercept. This overload pressure may be an amazing number of 80 to 90g, which can not be achieved by all active air defense missiles in the world.


    Moreover, if we want to intercept hypersonic targets, we need not only a missile that can catch up with the target, but also an air defense radar system that can lock it and a guidance system that can guide the missile to track the target.


    Only in this way can we intercept hypersonic targets.


    However, even if these three conditions are complete, they are only capable of intercepting hypersonic missiles.


    In order to intercept the air and space fighters with special stealth design for the fuselage, ultra-high maneuverability and high-altitude and high-speed penetration, humans must develop a more efficient air defense system.


    After understanding these situations, Chen Xin whispered something to the air force officers. After listening, the other party''s expression on his face became very wonderful, but he quickly nodded excitedly and soon left the tower.


    Many people in the tower noticed this scene, especially several foreign researchers.


    But at the moment, they all had a very tacit understanding. They didn''t even pay much attention to the scene. They saw it and pretended not to see it.


    Nowadays, the pattern of blue star is that all countries rely on Yanguo to live. If you go to inquire about something you shouldn''t inquire about and offend Yanguo, it''s not a small matter.


    Not to mention that they are all working on the territory of Yanguo people, and they rush to inquire about some things, which may be suspected of espionage. Just offending Yanguo and causing their country to be cut off by Yanguo is enough to send European countries whose situation has just improved back to hell again.


    In addition, Chen xinmingxian has an attitude that he doesn''t want people to know, so they can''t inquire about something they shouldn''t.


    Therefore, these foreign researchers look at the nose and heart from the eyes of the heart, with an expression that they don''t know anything.


    Chen Xin naturally saw the attitude of these foreign researchers, but he didn''t make any additional remarks.


    After all, what he just mentioned to the air force officer is really something that outsiders can''t know and inquire about. He himself regrets mentioning it on this occasion. He should find a safer occasion to mention it again.


    But just now he spoke in a very low voice. This is the air force base of Yanguo. I don''t worry that someone will overhear their conversation.


    Moreover, even if someone really overheard his conversation, these scientific researchers from Europe can''t send back the information. We should know that all their contacts with Europe depend on the communication channels of inflammatory country, and the Intelligence Department of inflammatory country will not be completely open for them to use.


    Therefore, Chen Xin soon relieved himself and left the tower after the aerospace plane returned.

 Chapter 849

    Although the whole air force base has been designated as the research site of the South Tianmen project, there are still some tests to be done elsewhere.


    After all, this is only an air force base. Although Yanguo has played a strong infrastructure force to transform it into a qualified laboratory after it is designated as the research site of the South Tianmen plan, it is a temporarily built research site, and some professional tests need to be carried out in other places.


    For example, the actual combat test of energy shield must use a professional weapon test site, which was not built at the air force base.


    Therefore, if Chen Xin wants to test the energy shield in actual combat, he must transport it to a place where this test can be carried out.


    Fortunately, many land-based ships in the base are responsible for the transportation of materials and personnel in peacetime. There is no problem in dispatching a land-based ship to take charge of this task.


    The energy shield was soon sent to a weapon test site nearest to the air force base, where the energy shield used for testing will be tested by various weapons now equipped by the Japanese army, including even various small missiles.


    The military attaches great importance to energy shield technology, because it is not only a technology that can be used for aerospace aircraft.


    In addition to aerospace aircraft, ordinary fighters, tanks, armored vehicles, land ships and mobile bases, as well as Titans and power armor, the equipment widely used and mounted in these countries can use energy shield technology.


    This will undoubtedly have a great impact on the army of Yanguo, because it will completely change the form of future war and have a far-reaching impact on the thinking of future war.


    After Chen Xin announced that shield technology had made a breakthrough, the Yanguo military had urgently convened experts in relevant fields to study and judge shield technology, and focused on analyzing the impact of this technology on future wars and the changes of military tactics and strategies after having shield technology.


    To take the simplest example, when an aircraft carrier has an energy shield to the power output of the nuclear reactor on the aircraft carrier, the aircraft carrier will not be afraid of any conventional missile attack, which greatly improves the survivability of the aircraft carrier.


    Individual weapons such as tanks or Titans, not to mention, with energy shields, human war mode is enough to move from reality to science fiction.


    Although the energy shield is not invincible and can still be broken, various war machines with greatly improved survivability will undoubtedly greatly change the form of war.


    A tank that could have been destroyed by a missile will greatly improve its defense capability after it has an energy shield. It may not be able to destroy it with ten times of firepower.


    Before humans developed weapons that can penetrate the energy shield, in the face of war machines equipped with energy shield, either use saturated firepower to consume the energy of the shield, or overload the shield with an instantaneous attack exceeding the upper limit of the shield, otherwise it is impossible to destroy a unit loaded with the shield.


    This means that anti-aircraft artillery must be used to attack mosquitoes. It must use much more ammunition than in the past to destroy a target.


    This alone is enough for the military staff to come up with all kinds of brain opening tactics and rewrite the current mode of war.


    It seems like a spiral cycle. For example, the former battleships have heavy armor, unparalleled defense and can resist the attack of various weapons. Even some battleships are strong enough to face the nuclear bomb.


    This also makes it impossible to sink a battleship at a certain time except that another battleship can destroy the battleship.


    Battleships have become the representatives of the strongest "shield". Countries all over the world are competing to build larger and thicker armored battleships.


    However, with the great bombing made by human beings more and more in line with the aesthetics of green skin, these weapons with a stronger sense of art smashed the "shield" symbolized by battleships, so the "spear" has become a new mainstream.


    Modern warships are the representatives of this school. They want to build warships with plastic. A warship can even be smashed and sunk by cargo ships.


    But their firepower is enough to easily send the representative battleships of the past "shield" to the bottom of the sea, so they don''t need defense at all, or humans can''t build a "shield" that can resist the current "spear".


    The energy shield technology is the new "shield", which makes the spiral of war go back. Now the "shield" is stronger than the "spear".


    The actual combat test of energy shield proves this in a very shocking way.


    The Yanguo military used all the conventional weapons equipped by the army, from various types of guns to explosives, and artillery of various calibres were pulled up all over, and even the air force stepped in. The Yanguo air force, which is ancestral to Tiandi, fired all the ammunition that can be used for ground attack, and almost let the rocket Army take out ballistic missiles and blow them up.


    However, under the attack of so many weapons, the temporarily modified 59 tank equipped with shield device as the target has always stood on the test field.


    Even the land beside the tank was ploughed down three points, but the 59 tank didn''t even rub off a piece of paint.


    Finally, the anti-ship missile originally used to destroy warships was pulled out. After activation, the light blue energy shield was extinguished after resisting a heavy anti-ship missile.


    This really shocked the Yanguo military. The defense of the tank itself is not worth mentioning. Although 59 tank was once the main weapon of the Yanguo military, its defense ability is not much better than that of paper in front of various modern weapons.


    Especially for various types of artillery and missiles, this is not an attack that a tank can withstand at all.


    But the 59 withstood such an attack and persisted to the end.


    This is enough to show that the energy shield is powerful and excellent.


    After obtaining such results, the Yanguo military reported the results at the first time, hoping to equip the whole army with this new equipment that rewrites the times.


    Of course, the senior management readily agreed and expressed strong support for this. They found Chen Xin at the first time and hoped that he could put the energy shield technology into practice and equip it with the main equipment currently equipped by the military to complete the upgrading of the army.


    From the high-level point of view, as long as the energy shield technology can popularize the whole army, it doesn''t matter what defense line they repair. Humans can launch a comprehensive strategic counterattack against alien creatures.


    Facing the requirements put forward by the senior management, Chen Xin just calmly took out the design drawing of Titan equipped with energy shield and the modification scheme of existing Titan.

 Chapter 850

    Although there is no large-scale invasion of alien creatures in Aleppo, sporadic attacks occur from time to time.


    The engineering teams of Yanguo and Lucia took the lead here to help the local garrison strengthen their defense to strengthen their defense and resist the possible attack of alien creatures from here.


    So far, the defensive situation of the defense line is normal. Although there are occasional large numbers of alien creatures, the pressure here is much less than the non-stop offensive like the tide in the European defense line.


    Otherwise, with the military power in the Middle East that is no different from playing for the inflammatory country, they have long been pushed flat by alien creatures.


    Now, with a stronger defense line, it is easier to resist the attack of alien creatures.


    Of course, although it is easy to resist the attack of alien creatures, it does not mean that the defenders here can become easier.


    On the contrary, after knowing the real scale of alien creatures, the garrison in Aleppo is obviously much more tense than before.


    Before Yanguo and Lucia came to help them strengthen their defense lines, they thought it was only a regional disaster. After all, the intensity was not strong, and they could resist it only.


    Countries in the Middle East even thought it was some kind of marine life that had never been found before, but it had been living on the seabed before, and it appeared on land with the disaster.


    Therefore, although they concentrated most of the military forces left in the Middle East after the disaster to fight in Aleppo, they were basically in an attitude of preventing biological pests.


    However, when Yanguo and Lucia appeared one after another, took out equipment similar to science fiction movies and began to attack alien creatures, and told them that this monster was an alien invasion to occupy the world. Now Europe is being attacked in an all-round way, these Middle East oilmen are completely ignorant.


    At first, they thought it was a joke. After all, after a disaster, Yanguo took out land ships and power armor, which are no different from science fiction movies. They said that they are the invading aliens, which are more reliable than those monsters who are alien creatures.


    But when all kinds of data and video records are put in front of these oil men, they still have to believe that the world has changed.


    In particular, the Yanguo people simply put them on land ships and took them around the European battlefield. After seeing the offensive that would drown the earth like the rising tide of the sea, these oil men had to choose to believe it.


    So their army moved like a donkey kicked in the ass, cooperating with the Yanguo and Lucian to strengthen the defense line.


    Moreover, these oil men also took out all their family assets, bought a large number of new weapons and equipment from Yanguo, re armed the general team, hired Yanguo people as instructors, and put all the troops back into training.


    The purpose is to improve the combat effectiveness of these troops so that they can better protect themselves.


    Although Yanguo and Lucia do not deny the practices of these oil men, their willingness to cooperate is naturally a good thing.


    That''s why Yanguo sent high-level officials to be responsible for the construction of the Middle East defense line and the construction of dome cities for these oilmen and Middle East dignitaries.


    However, these have nothing to do with the troops stationed in Aleppo. They have not been affected except for new equipment and hard training.


    After all, they will not retreat unless their current line of defense is completely broken.


    The dome city built on the Iranian plateau is not what these big soldiers can think of. Instead of thinking about these unrealistic things, it is better to spend more time training so as to survive the war.


    Maybe you can be promoted and transferred from the front line, go to the Dome City as a guard for those big people, and live in houses that are said to have plants and sunshine.


    For the defenders of the Aleppo line, it can be said that it is their ultimate goal and dream to be transferred back to the rear and become the escort of big people.


    However, even so, they only think about it occasionally. It is more practical for them to live.


    Although the attack of alien creatures that Aleppo''s defense line needs to face is not strong, it is still facing the invasion of alien creatures after all. Even if the defense line is upgraded and the defense becomes more stable, people are still killed every day because of fighting with alien creatures.


    However, the situation today seems to be somewhat different. It seems that those Yanguo people sent to train them have received some orders to transfer an army as preparation to cooperate with their actions.


    However, the people of Yanguo did not tell the defenders what action they wanted to cooperate with. They just asked them to change their equipment and assemble. After that, they fell into waiting.


    As for what to wait for, the people of Yanguo always avoided talking, and sent people to stay at the forefront of the defense line and look at the sky with night vision, as if there was something to come from the sky.


    Some of these defenders don''t know the situation, but now these Yanguo people are in charge of command. They are asked by the high level to cooperate. Naturally, they can only wait obediently according to the orders of Yanguo people.


    When they were bored, these people seemed to wait for what they were waiting for and began to signal to the sky.


    Then, these defenders who consciously had seen the world saw the Titans falling from the sky.


    Twelve new titans of a squadron equipped with shield system, twelve old titans of a squadron equipped with shield equipment, and a command plane were thrown down from the sky by two specially modified land ships.


    Titan is not without airdrop, but in the past, most of them used low altitude airdrop, or simply a helicopter to lift it to a designated position and put it down.


    This time, however, they dropped 25 Titans from an altitude of 5000 meters above the ground.


    In the cockpit of Titan, many pilots looked nervous, but only the drivers of 12 old Titans equipped with shields were nervous, while the drivers of the other 12 new Titans did not.


    Because the twelve new titans are unmanned Titans, they are equipped with weak artificial intelligence and have certain autonomous combat capability. A command aircraft is responsible for command and control.


    This time, Yanguo will put them into the Aleppo defense line to test not only the airborne equipment, but also the actual combat capability of the new unmanned Titan.


    "It has reached the parachute opening height, all aircraft open their parachutes!" the command plane issued a command and also opened its own parachute.


    So, in the surprised eyes of the garrison on the ground, umbrella flowers bloomed in the sky.

 Chapter 851

    With the decline of height, the disposable recoil rockets carried by these Titans began to ignite, further buffering their falling speed, but finally they hit the ground with a dull sound of "Dong".


    Although this generation of unmanned Titans has made room for the cockpit and subtracted a driver of more than 100 kg, they have inserted a control core weighing more than 10 kg and a shield device weighing at least 100 kg. Coupled with supporting energy upgrading and weapon strengthening, the weight of unmanned Titans is heavier than that of general-purpose Titans.


    Of course, equipped with shields and upgraded energy, they are also stronger in combat capability.


    Twelve unmanned Titans and twelve general-purpose modified titans are all equipped with 30mm machine guns that have been tested in actual combat and recognized as the best used by all Titan pilots.


    This is the best weapon recognized by Titan pilots on the battlefield. 30mm shells can effectively kill alien creatures, and can more effectively cause penetration damage after carrying armor piercing bullets. The high firing speed of machine guns also ensures the sustainability of firepower output, which is very effective to deal with the continuous attack of alien creatures.


    In addition to machine guns, the general-purpose modified Titan is also equipped with four 75mm portable guns. Although this weapon is not as popular as the 30mm machine gun, it is still a popular weapon.


    After all, portable rapid fire guns can be more lethal than machine guns, and incendiary bombs are the favorite of some Titan pilots who advocate firepower.


    Using incendiary bombs to quickly blast a wall of fire on the battlefield can effectively delay and affect the attack rhythm of alien creatures, interfere with their attack waves, and cause effective damage to alien creatures. It is a weapon loved by Titan pilots.


    The same is true this time. After landing, the four general-purpose modified Titans equipped with portable guns quickly adjusted their posture and began shelling.


    As for the other eight Titans, four of them are equipped with chainsaw swords for close combat, which is also recognized as one of the most effective weapons against alien creatures. In close combat, a roaring chainsaw sword can''t be better. They can very effectively cut alien creatures into a pile of fragments, and the effect is quite outstanding.


    In addition to the fact that the ground service is easy to scold when cleaning up after the war and blood splashes ten meters when using, there is only the problem that the serrations are seriously worn and need to be replaced frequently.


    However, this time, because they were equipped with shields, they did not intend to use chainsaw swords to fight close combat, but were strafing with machine guns as much as possible.


    "Captain, you can''t test the shield like this! Do you want to send some dogs over and let them chew the shield?" a general-purpose modified driver suggested to the captain on the communication channel.


    Twenty five Titans output enough firepower to form a death barrage. No alien creature can cross their firepower blockade.


    In particular, because the twelve unmanned titans are controlled by artificial intelligence, their killing efficiency is even 30% higher than that of human drivers. Almost every bullet can take away an enemy.


    Moreover, their auxiliary weapons are more targeted than those carried by the general-purpose modified Titan. In addition to six hand guns, they also carry two sniper guns and four dense arrays.


    The so-called sniper gun is an improved product of the electromagnetic plasma dual-purpose gun on Zhu Luan of Qin LAN. At that time, the military was very greedy for the gadget, but in the end, it still couldn''t bear the cost and chose the electromagnetic sniper gun after reduction.


    Special ammunition is launched through the magnetic track to accelerate the projectile to Mach 30. Even if it is only a solid warhead, it is powerful enough to penetrate everything.


    In fact, in the test of the energy shield, the electromagnetic sniper gun was a weapon that almost broke through the energy shield. A special armor piercing bullet penetrated the shield, but when it passed through the shield, the kinetic energy was exhausted and the lethality was lost.


    "Bite a hammer, don''t look for trouble. Although we''re here to test the shield, we''re not asking you to take the initiative to test!" the captain spoke with a Sichuan accent. At the moment, he was sitting in the command plane, commanding the unmanned Titans and the manned universal modified Titans.


    Although it is said that their combat mission includes testing the ability of the shield to withstand the attack of alien creatures, before coming, the superior has told us not to take the initiative to withstand the attack of alien creatures with the shield. If there is no suitable time, this test will not be done, and the highest priority is to ensure the survival of the body and the driver.


    Therefore, although after landing, alien creatures have found them and launched an attack on them, the captain has arranged a strict fire blockade network to eliminate the possibility of alien creatures crossing the fire network and fighting them at close range.


    On the new unmanned Titan, although it is equipped with electromagnetic shield, the large explosion-proof shield originally loved by Titan drivers is still installed in a row, and every one has it.


    However, the connection form is no longer to let the Titan hold it in his hand, but changed to a mechanical arm with limited angle of movement, hanging the shield on the Titan''s left shoulder.


    In addition, on the new unmanned Titan, these shields have also been upgraded, equipped with explosive reaction armor and strong light flash, which has achieved good results in actual combat tests.


    The manipulator can adjust the angle of the shield at any time, so that it can more effectively bounce off and defend against the attack of alien creatures, and even the shooting of the tank main gun. It can be said to be a very powerful defense equipment.


    In fact, before the shield technology came out, military designers planned to popularize the combination of shield and manipulator to all general-purpose Titans.


    As for the male type, their body structure makes it impossible for them to use shields. They can only install gun shields on machine guns, rotary tube machine guns and portable guns.


    "No. 9, No. 10, release the UAV! Investigate the battlefield situation, and everyone retreated slowly and approached the defense line." although the firepower of more than 20 Titans was excellent, the ammunition they carried could not maintain their high-intensity operation for a long time, so the captain soon ordered them to start moving backward.


    Their airdrop position is just in front of the Aleppo defense line, and their fighting figure can be seen on the defense line, so as long as they move back a little, they can get effective support from the defense line.


    After all, they were airborne operations and carried very limited ammunition. Even if two boxes of ammunition were thrown down with them, it did not prevent them from completing the test mission with the help of the defense of the defense line.


    They are here to test the actual combat effect of the new Titan and the play of the shield in the actual combat, not to let them do much damage to alien creatures here.

 Chapter 852

    Two squadrons of Titan mecha were put into the battlefield, mainly to test the combat effectiveness of the new body.


    Therefore, the Titan mecha of the two squadrons were not assigned specific combat targets. What they received when they were put into the battlefield was a series of test targets, and the specific combat plans were completely formulated by the leaders of the two squadrons.


    In fact, even if the superior departments want to formulate specific operational plans or arrange specific operational objectives for them, it is impossible to talk about. After all, there are no conventional operational tasks such as pulling out fire points, attacking defense nodes and beheading the headquarters when fighting with alien creatures.


    When the troops are pulled to the battlefield, there is only one thing they need to know. Pull the trigger and shoot at alien creatures. The more they can kill, the better.


    After all, what you are facing is that you don''t follow your tactics and strategies at all. You are playing with a wave of alien creatures of the whole family. You have no choice but to be hard.


    For the two Titan squadrons that need to test the performance of equipment, it will test their on-the-spot ability.


    In particular, they were directly thrown on the front position with the most intense battle on the battlefield. The battle intensity here is the highest, and behind it is their own defense line. It is also convenient to retreat. It is indeed an ideal practical test site.


    But in this way, what they need to face is an endless sea of worms.


    For the captain of Titan Squadron, he can let his players retreat while playing, retreat below the defense line, and rely on the defense line to test these weapons he brought.


    This is the safest and safest solution.


    However, the equipment they want to test also includes the latest technology of energy shield, and the focus of their test is energy shield.


    Obviously, their strategy can''t be too conservative. If they don''t have an approach battle with alien creatures in the whole process, and can''t test the play of shield in actual combat, it''s obviously not in line with the predetermined goal to shoot with weapons.


    Therefore, although the captain let the team close to the defense line, he did not let the team directly rely on the defense line to fight. They were still a short distance from the defense line.


    Although the team did not put one or two alien creatures to chew the shield as the team members said at the beginning, the team leader still asked the team members to start saving bullets, control the firing rhythm and consciously reduce the density of the fire net.


    If it was in the European defense line, the captain would not dare to do so, because it would be difficult for them to survive, let alone test the shield.


    The attack intensity of alien creatures on the other side of the European defense line is far higher than that here in Aleppo defense line. The attack waves of alien creatures like waves crashing on the shore are enough to completely submerge them.


    Even if their firepower is fully open, they may not last long, let alone reduce the firepower density.


    However, Aleppo is somewhat different. The attack intensity of alien creatures here is far from that high. Slightly reducing the density of some firepower networks and adopting a more ammunition saving combat method will not take too much risk.


    But even so, after the Titan squadron reduced the density of the fire net, few alien creatures could break through the fire net.


    Even if one or two can break through the blockade occasionally, they are still killed quickly, and there is no chance to test the strength of the shield.


    "Captain, 27 new weapon tests and 136 unmanned Titan actual combat tests have been completed, and there are still 13 energy shield tests left. I still suggest that we send some alien creatures to chew the shield, which can complete the test quickly." a team member checked the tests they need to do one by one through Titan''s onboard computer, Seeing that only the test of energy shield was left, he proposed to the captain again.


    Hearing the team members say so, although they still don''t want to do so, the captain said: "continue to move backward. After approaching the defense line, everyone will turn to alert mode and hand over the battle to the unmanned Titan."


    "Yes!" the team members answered and began to move again.


    At this time, the troops waiting to meet them on the defense line have also entered the combat position, but the fire of the Titan squadron is too fierce, and they are of no use for a while.


    "Do we need to support them? They seem to be running out of ammunition." a garrison suggested to the Yanguo officer. From his perspective, the firepower of these big guys dropped by air has been declining, and now half of the body doesn''t fire much, which is undoubtedly a sign that the ammunition is almost exhausted.


    However, Yanguo officers are more familiar with their own equipment and the combat style of their own soldiers. Obviously, they can''t be without ammunition.


    However, he nodded and said, "provide fire support for them. Don''t fight too hard. They come to test their equipment and leave some enemies for them."


    "I see." the garrison immediately sent down the order.


    Soon, the defenders began shelling and other fire support, and the Titan squadron retreated to the front of the line.


    Instead of retreating into the defense line, they set up a guard formation, turned the GM modified Titan into a guard firing mode, and handed over the main fire output to the unmanned Titan.


    This undoubtedly makes them look like they really consume too much ammunition and have to reduce the design frequency.


    However, in fact, although they did consume a lot of ammunition, at least one third of them were enough to support them to fight for a long time.


    "The garrison began to attack, captain. Should we send some dogs to chew the shield? The task can''t be completed in this way!" the team members continued to propose to the captain looking at the shells fired from behind the defense line.


    However, he had just finished his words. A shell that seemed to be a mortar shell fell next to them and exploded. Shrapnel, blown snow and soil hit the shield of half of the squadron Titans and threw a blue light.


    "They hit by mistake?" the team members couldn''t believe it. He didn''t expect that the shield that alien creatures didn''t bite was lit up by friendly forces.


    "It''s probably a mistake. Do you have the parameters of the shield test?" the captain asked the team members. In fact, he was more concerned about whether the task could be completed than the team members, but he couldn''t deliberately send alien creatures to test the shield. It would take a much greater risk to do so.


    "There are parameters, but some things need to be tested." the team member answered positively. At the same time, he also found another discovery: "in addition, when the shield is activated, we can''t shoot from the inside out. Our bullets will also be blocked by the shield. We have to report this back!"

 Chapter 853

    "Academician, this is the actual test report of unmanned Titan and GM modified Titan on the Aleppo defense line." a staff member sent a report to Chen Xin.


    "The next time this kind of report is sent directly to the electronic version, it will be more efficient." Chen Xin took over the report, said a word casually and opened the report. However, after a brief browsing, he frowned and raised his head: "they were mistakenly hit on the battlefield?"


    "Yes, at that time, the garrison used mortars to try to cover and fire support them, and a shell fell around them." the staff had read the report before, and Chen Xin could naturally answer when asked why.


    Hearing the staff say so, Chen Xin shook his head with dissatisfaction.


    Although it is inevitable that there will be accidental attacks and injuries on the battlefield, he instinctively doesn''t like such things.


    Continue to read the report, turn to the summary table of various tests, and look at several unfinished labels. Chen Xin asked discontentedly, "the tests of other projects have been completed well. How many tests of shield have not been completed?"


    "The unmanned Titan''s combat effectiveness is very high, and the general modification also plays a good role. If they ignore the ammunition consumption, no alien creature can pass through their fire network, so some close combat tests really can''t be carried out." the staff defended the pilots, and he explained to Chen Xin: "Academician, you have explained that the test is safety first, so during this actual test, they have been carrying out according to the normal combat process, and have not taken the initiative to test the effect of the shield."


    "Oh, if so, it''s no wonder they didn''t complete the task." Chen Xin shook his head. If so, the problem is not with these drivers.


    Although he is not so satisfied that the test has not been completed, Chen Xin is obviously not that kind of rigid dogmatism. He will not ask the soldiers on the front line to complete the test, or even take some risks that they don''t need to take in order to test.


    "Have the test troops withdrawn?" Chen Xin asked the staff.


    The test task is not arranged by him personally. The following staff are responsible for these things. Chen Xin only needs to pay attention to the results.


    As for the concern about whether the test troops have withdrawn, it is necessary to check the airframe that has been tested in actual combat and recover the test data at the same time.


    "They are returning. They should be back in the afternoon." the staff looked at their watch and reported to Chen Xin.


    Those test troops will not come to the air force base. They will be sent to the scientific research center, which is the Department responsible for the development of Titan''s new body.


    Although the unmanned tactical aircraft armor is a part of the South Tianmen plan, the air force base where Chen Xin is now mainly responsible for the R & D of large-scale Aerospace strategic carrier platforms and aerospace unmanned fighters, and other projects are not here.


    "After coming back, let the research department complete the data recovery as soon as possible, and analyze it to see where there are problems." Chen Xin ordered the staff and emphatically told them: "although the more mature technologies are used, the more so, the more careless, and we must not let go of any possible problems."


    Speaking of this, Chen Xin paused a little before continuing to say to the staff: "now it''s different from before. Before, we had to provide the troops with usable equipment at the fastest speed. It''s acceptable to adjust some minor defects in actual combat.


    But now the war situation has changed. What we need to do is to provide more reliable equipment for the troops. Now we need to solve the problem of good and precision, not whether there is a problem as before. "


    "Yes, academician!" the staff quickly answered and wrote down Chen Xin''s words.


    Although Chen Xin is not directly responsible for the project of the new Titan, as the general director, he obviously has a direct influence on the project. In particular, he personally provides the design drawings and shield technology, which makes Chen Xin not only have enough influence but also have enough control over the project.


    Of course, Chen Xin will not use his influence to interfere in the project. He also hopes that the project can be completed better.


    Having said this, Chen Xin asked the staff to leave, and he turned over the test report in more detail.


    This report mainly records what items the driver completed during the actual test, as well as some simple opinions of the driver.


    It is more appropriate to say that it is a Task Briefing than a test report.


    As for more detailed test reports, more detailed and accurate results can only be obtained after the test troops return home and those bodies are sent to research institutions for data collection and analysis.


    However, even in the task briefing, the feedback provided by the driver at the first time still has a very valuable reference value, so Chen Xin looked at this part very carefully.


    "When the shield is activated, you can''t attack from the inside?" Chen Xin noticed one of the feedback and understood it after a little thinking.


    Although the energy shield is a new technology and a very cutting-edge technology, as far as the energy shield itself is concerned, the electromagnetic shield made by Chen Xin is actually quite rough and primitive.


    In fact, it is just a simple and crude way to restrain high-energy charged particles into a shield through magnetic restraint device, and there is no more precise or advanced use.


    It''s like simply building a wall with random stones, not stacking it neatly, let alone turning the wall into a fortification with complete energy supply.


    Therefore, although this shield can intercept attacks very effectively, it is undoubtedly a two-way barrier. The outside can''t hit the inside, and the inside can''t hit the outside.


    The reason why those test airframes are still in normal use and have been in normal operation is that the shield has not been activated, but is in standby mode, which does not interfere with their operation.


    At the thought of this, Chen Xin couldn''t help but be in a cold sweat. If there was a close combat, the shield would be activated by the close combat attack. In this case, although the alien creatures could not hurt the body and driver in the shield, the Titan could not attack the enemy outside the shield.


    Unless the shield is turned off, bullets and missiles will be intercepted by the shield.


    This problem must be solved! Chen Xin immediately wanted to open the system upgrade interface to upgrade the shield, but after thinking about it, he gave up the idea and sent it to the project team to try to solve the problem.

 Chapter 854

    When Chen Xin''s project teams are trying to overcome technical problems and continuously contribute to the progress of the South Tianmen plan, the new urban expansion of the new city has also been completed.


    Of course, the expanded new urban area is not broad and comfortable. After all, it is designed on the premise of residential resettlement area, and it is impossible to sacrifice living space to give comfort in this environment.


    On the whole, however, this is still a satisfactory new urban area. At least those who have obtained the housing qualification and can move in are still very satisfied.


    Moreover, although the whole new urban area is slightly compact and cramped in planning, it can not be compact. After all, it is only a small dome only a quarter of the size of the new city dome, and the area and space are really limited.


    However, the designers still try their best to make the new urban area look beautiful. They also painstakingly designed green belts in various places to make the city look a little more comfortable than a steel jungle.


    In order to get better lighting, all buildings in the new urban area adopt a cross design, which makes the new urban area look different.


    "At present, the occupancy rate in the new urban area has reached 70%, and the residents who have obtained the housing qualification are actively moving, and the main urban area of the new city is also actively removing the vacated movable plank houses and some temporary buildings. Generally speaking, everything is going well." in Chen Xin''s office, Tang Tang is reporting the situation of the new town to him via Internet phone.


    As they planned before, some people who have obtained the residence qualification move into the new urban area, freeing up the space in the main urban area.


    Some of these vacated spaces are used to relocate people who were originally crowded in movable plank houses or temporary additional buildings, and some are rebuilt according to the planning of the previous municipal meeting.


    After such a change, although the living environment in the new town can not be said to be much better, it has also been greatly improved compared with before.


    Moreover, the re planned cities and functional areas can also make the city more beautiful and reasonable and more convenient for people''s life.


    "Sounds very good, isn''t there any trouble in the municipal administration?" Chen Xin asked Tang Tang Tang with concern.


    He knows how much work can be done for such a large-scale housing distribution and population living environment adjustment. Even though he has done a lot of preparatory work before, he has also done some hair blowing work.


    But things in this world have never been oligopoly but uneven. Even if the house is small, it is a new house!


    And it''s not a set of people. If someone gets a house, naturally someone can''t get a house.


    Although the country now has a strong executive power, and even more than at any time in history, the country needs the support of the people, no one can guarantee that no one will make trouble when it involves its own vital interests.


    For this problem, Tang Tang Tang shook his head and said, "it''s not a big problem. Although some people are really angry and have come to the gate of the city government, it''s basically not a climate. It''s just an individual making trouble.


    The staff of the municipal government will persuade them to leave. If they don''t listen to the advice, the police will directly arrest them by making trouble and causing no trouble. "


    "That''s good, but you still have to tell the city government to pay attention to the ways and methods of dealing with the problem. Don''t be too rude, resulting in some uncontrollable consequences." Chen Xin thinks it''s still necessary to remind the city government to pay attention to the means of dealing with the problem.


    Although it is said that heavy codes are used in troubled times and policies are very important in extraordinary times, we should pay attention to the impact of things that should be paid attention to.


    "I''ll tell them, but I don''t think there''s any need to worry about the city government. They are all experienced veteran cadres and there will be no problems in this regard." Tang Tang Tang understood Chen Xin''s concerns, but he didn''t worry too much.


    After talking about the new urban area, they talked about some work matters. Chen Xin asked, "by the way, how is the upgrading of scientific research institutions in the new city? Didn''t it say that we should take the opportunity of municipal transformation to transform the original office building and improve the office environment and scientific research conditions? How is it going now?"


    "Everything is going well. At present, the office is being rebuilt, a lot of new things have been added, the office network has been rearranged, and a lot of new instruments and equipment have been added. Everyone is looking forward to it." Tang Tang Tang mentioned this matter with a little more joy and expectation, and said to Chen Xin with great interest: "After the new office building is built, I must choose an office with big windows!"


    "Anyway, you are in charge of the distribution of the office. You can reserve any position for yourself." Chen Xin doesn''t care about this. With the rising of the sun, the office with windows has become popular again. After all, everyone wants a sunny office.


    Unlike before, rooms with windows are relatively cold, and rooms near windows are not comfortable.


    "Then I''ll choose the best one for myself." Tang Tang Tang said half jokingly. Although she didn''t intend to leave the best office to herself, she really wanted to choose a room with large windows and good lighting.


    They chatted some more gossip and hung up the communication.


    After hanging up the communication with Tang Tang Tang, Chen Xin leaned against his chair and asked Xi Yao to call out the recent work plan and research progress.


    As the general director of the whole Nantianmen project, Chen Xin works a lot every day. Although relying on the operation of Xiyao, he does not need to personally intervene in many things, he must pay attention to and understand the project research progress.


    At present, the research progress of the whole Nantianmen plan is still in line with expectations, and the theoretical basis has been almost perfect. Many project teams have begun to trial produce the technical verification machine of their own projects.


    This also led to the long printing schedule of the two large 3D printing equipment set in the base. Several project teams typed the report to him and asked for higher priority and give priority to their printing plan.


    Chen Xin doesn''t want to interfere in this kind of thing. If he really gives priority to any plan, more people will come to him to open the back door.


    Therefore, he called back all the application reports, and the scheduling and priority of 3D printing equipment were handed over to Xiyao for comprehensive allocation according to the importance of the project and the existing queuing order, so as to ensure absolute fairness and justice with artificial intelligence.


    Chen Xin did solve the dispute. After all, artificial intelligence really has no face to talk about, and there is no possibility of favoritism in the program, so everyone obeyed Xiyao''s distribution.


    Although Chen novice still has the authority to modify Xiyao''s allocation results, no one will call him again and ask him to give priority to his projects.

 Chapter 855

    Of course, the most difficult thing to complete in the South Tianmen plan is the large-scale Aerospace strategic aircraft carrying platform.


    After all, it is more than 200 meters long and more than 600 meters wide, which is equivalent to the huge size of four aircraft carriers. Even if it is not a problem to fly with an anti gravity generator, trying to make such a huge thing is still a severe test of human industrial manufacturing capacity, materials science and structure.


    Building an aircraft carrier has been a great test of a country''s overall industrial strength.


    Just like the passage circulated on the Internet, it needs "the National Planning Commission, the military industry commission and nine ministries of national defense industry, 600 related majors and 8000 supporting manufacturers". This is not a job that can be completed by a shipyard, but a strong country with strong national strength.


    It is almost impossible to build an airborne aircraft platform several times larger than an aircraft carrier.


    This is not only a technical problem, but also a problem of industrial production capacity.


    Not to mention anything else, just the 100000 tons of qualified high-performance steel made from this stuff can''t be made even by smashing the pot and selling iron for many small countries.


    Not to mention that the materials used in some places are much rarer and more expensive than high-performance steel. Maybe some small countries sell them all, and they may not be valuable.


    However, this time, all the existing countries of mankind are involved in the construction, which is not a problem in terms of materials.


    In particular, Chen Xin''s previous efforts in Europe, the mining and smelting of various mineral resources and the synthesis of high-performance materials are not too big problems.


    The mining sub bases all over Europe provide sufficient raw materials for the construction of aircraft carrying platforms.


    However, there are only materials, which need to be processed into parts.


    You should know that the carrier platform is more than 200 meters long and 600 meters wide. In order to ensure sufficient structural strength, many parts are surprisingly large.


    For example, the length of some components of the main support structure of the carrier platform is even more than 100 meters!


    Such a huge component has never been manufactured in human history, because nothing needs such a large part.


    Even if there were components with a length of hundreds of meters in the past, they would be manufactured by splicing multiple parts, rather than manufacturing such a huge part as a whole.


    If it weren''t for 3D printing technology, I''m afraid we would have to study how to make such a large part first.


    Moreover, even with 3D printing technology, to manufacture such a large component, it still needs to redesign the printing equipment, and the existing printing equipment is difficult to complete its manufacturing work.


    Moreover, even if such a huge part is manufactured, how to ensure that its structural strength meets the requirements is a headache for the project team.


    All this needs the overall coordination of Chen Xin, the general person in charge, which tests his ability even more.


    If Xiyao, an artificial intelligence, had not assisted him and helped him deal with a lot of trivial affairs, I''m afraid he would be really tired to death.


    Fortunately, the country is also aware of the difficulties of this project and has deployed a large number of experienced administrative and technical personnel.


    These people may not be able to help much with the improvement of the theoretical basis, but they can play too much role in the actual construction of the carrier platform.


    Experienced administrative personnel can coordinate the cooperation and communication between departments, make the cooperation between departments more smooth, and also solve the "small problems" in the process of mass production and manufacturing.


    The technicians can better complete the production and manufacturing work. For some problems that may not be aware of or will not be found on the drawings, the technicians on site can find and deal with them in the production and manufacturing process.


    However, even with these conditions, it is still not easy to build a large-scale Aerospace strategic carrier platform.


    In order to avoid waste and verify the technology, Chen Xin decided to build a small scaled down carrier platform for technical verification. At the same time, he can also accumulate experience for the real design and construction of large space strategic carrier platform.


    This scheme was quickly recognized and supported by all parties. Everyone also felt that it was more reliable to do a technical verification first than to directly start building big guys.


    After all, those large parts of more than 100 meters are really difficult to build, and they really don''t have any relevant experience.


    If we can build a smaller one first, verify whether the structural design is reasonable, or find the possibility of changing large parts into small parts, it is very beneficial for the construction of the whole empty space carrier platform.


    Therefore, under the condition that each project team improved the basic theory, a small carrier platform reduced by nearly ten times was built.


    This carrier platform is not a scaled down version of the large carrier platform expected to be built. Although it is similar in structure, its drawings have been carefully designed.


    Moreover, the carrier platform also has the same performance indicators as the large carrier platform, and can also launch UAV operations.


    However, the UAV mounted on this small carrier platform is not an aerospace aircraft that can basically enter the design finalization stage, but some specially designed small UAVs.


    This small carrier platform is only more than 20 meters long and more than 60 meters wide. It looks like an airliner with extremely long wings.


    The main part of the fuselage is the crew cabin and control center to accommodate personnel, as well as a UAV maintenance workshop specially prepared for the carrier platform, while on both sides of the fuselage are two UAV launch tubes.


    This is a new technology specially developed for the airborne aircraft platform. It can launch UAVs quickly at high altitude, recover and maintain them. It is an important basis for the formation of the operational concept of the airborne platform.


    As for the huge wing whose wingspan has completely exceeded the design of ordinary aircraft, this is one of the key points of this technical verification.


    Because of the use requirements of large Aerospace strategic carrier platform, the design of such a large span is in line with its positioning, but this large span design is also a torture to the wing structure and materials.


    After all, we all know that the longer something is, the easier it is to break, and so is the wing.


    It is not a simple thing to make it long enough and strong enough to meet the needs of aircraft flight.


    Fortunately, the whole South Tianmen project has gathered the world''s top scientists and scientific research teams. It is difficult for them to be defeated by a wing with a wingspan of more than 60 meters.


    As for the energy and power of this small carrier platform, it is relatively simple.


    A small nuclear reactor is installed on the carrier platform, together with an anti gravity generator and a shield device, which provides it with abundant energy, a more convenient way to rise into the air, and sufficient safety protection.

 Chapter 856

    Driven by the anti gravity generator and two large thrust engines, the small carrier platform took off smoothly along the runway.


    In terms of flight mode, this small carrier platform is not fundamentally different from the land ship, but the carrier platform is lighter, more aerodynamic in shape and structural design, and more suitable for flight.


    At the same time, due to different positioning, the carrier platform needs higher flight speed. The engine equipped with it also has greater thrust than that of the land ship, and can fly at higher speed.


    Moreover, because of its own positioning, the carrier platform is designed to stay in the sky for a long time. Although land-based ships can also do this, it is obvious that it is not designed for this purpose, and there is still a big gap in self-supporting ability.


    The same is true for the test flight of the small carrier platform. The carrier platform will stay in the sky for at least one week to test whether the carrier platform can operate normally and whether there will be problems when it is stuck in the air for a long time.


    Chen Xin didn''t intervene in the whole process of the design and manufacturing of small carrier platform. He just approved the project and coordinated the resource allocation.


    It can be said that apart from the nuclear reactor, anti gravity generator and shield device provided by him, other parts of this small carrier platform are the achievements of existing human science and technology.


    Therefore, Chen Xin pays more attention to the test of this small carrier platform than others.


    Others thought that this was because he was the general director and showed special concern for the project, which was a serious and responsible performance.


    However, in fact, Chen Xin is curious about what kind of achievements can be made without his help.


    Although it was often said on the Internet before the disaster that the only things restricting the development of human science and technology are energy and materials, as long as these two problems are solved, human science and technology will usher in another big outbreak.


    However, science and technology are not so easy to break out. The so-called science and technology explosion is actually some ideas that could not be realized due to the limitations of materials and energy.


    These assumptions are based on the existing technical theory and have the possibility to realize some designs, but the existing energy mode and material properties can not meet the design needs.


    When there are energy and materials that can meet the needs, these ideas can be realized. Naturally, it looks like a sudden blowout of science and technology. However, it only realizes the design that could not be realized. As for science and technology itself, there is no new East and West.


    Of course, after having these realized ideas, based on these ideas, new technologies will indeed be developed. It is only known whether the blowout can meet people''s expectations.


    At present, the carrier platform can be regarded as an idea that could not be realized, which has been realized with appropriate energy.


    Therefore, in a sense, the performance of this aircraft platform can be regarded as a comprehensive embodiment of human science and technology, and can also be extended to a test of whether human beings can really bring a scientific and technological blowout after having more reliable nuclear technology than originally.


    Although Yanguo has indeed ushered in vigorous development in science and technology after obtaining the nuclear battery and nuclear fusion technology provided by Chen Xin, there is still a certain gap from the statement of blowout.


    The South Tianmen plan, which is jointly participated by many countries, integrates the science and technology of various countries. With such a scientific and technological foundation, coupled with reliable energy technology and some black technologies that have been listed by Chen Xinkai, mankind actually has the necessary conditions for the scientific and technological blowout.


    If on this basis, humans can not build a reliable carrier platform, which is not too high-tech, then it is indeed too early for humans to have a scientific and technological blowout.


    Fortunately, so far, the test of the carrier platform has been carried out smoothly. The whole carrier platform has successfully lifted into the air, entered the predetermined cruise altitude, and flew smoothly.


    In the next week, it will continue to fly continuously, during which various tests will be carried out, including UAV launch and recovery, high-altitude material supply and other projects, and the seven crew members on the carrier platform will always stay on it to test the life maintenance ability of the carrier platform.


    After all, according to the design, the large Aerospace strategic carrier platform will fly at high altitude for a long time. The self-supporting capacity needs to reach three months according to the design standard, and it should meet the survival needs of at least 1000 people.


    This requires very high requirements for its internal survival cycle system, and its difficulty is no less than designing the survival cycle system for the space station.


    If there are few people, the pressure is relatively small and the design is relatively simple. If the small carrier platform can operate smoothly, the large platform can be developed on its basis.


    Therefore, although a carrier platform is small, it carries a lot of things.


    Even in a sense, it can be regarded as the phased achievement of the South Tianmen plan after such a long time.


    It is also the test of the work results of Chen Xin and all participants of the whole Nantianmen plan during this period. Therefore, Chen Xin also bears considerable pressure and responsibility.


    He even wanted to transfer a land carrier to carry him. He followed the carrier platform all the way in the past few days and participated in the test all the way.


    However, in the end, he still didn''t do so. After all, there are too many things he needs to participate in the whole Nantianmen plan. He doesn''t have a week to spend on this test, and the senior management can''t approve him to stay in the sky for a whole week.


    Therefore, Chen Xin had to stay in the base and could only obtain the test information through remote monitoring and communication with the carrier platform.


    Fortunately, the work of other researchers was also fruitful. There were no problems in the preliminary test of the carrier platform, the flight was very stable, and all equipment operated normally.


    As for whether there will be problems in the future, it depends on whether the operation of the carrier platform is good in the next week.


    Before that, humans had not made such an aircraft that could fly at high altitude for a long time. The last aircraft that humans made that could stay in the sky for a long time was an airship.


    Therefore, no one is sure whether the carrier platform can run smoothly for a long time. Before the test results come out, everyone can only wait with expectation.


    Chen Xin did not stay. He left the monitoring room after the carrier platform entered the cruise altitude and flew smoothly.


    Only when he returned to his office, a researcher stopped him.

 Chapter 857

    "Sir, my team and I have come up with a plan. I''d like you to have a look." the researcher who stopped Chen Xin handed a design plan to Chen Xin with great expectation on his face, but he looked quite nervous.


    Chen Xin frowned at the researcher and looked at the design scheme in his hand. He hesitated before taking over.


    After receiving the plan, Chen Xin didn''t look at it immediately, but asked him, "who are you? What is this plan? Why show it to me directly instead of submitting it to your upper level department?"


    The ID card hanging on the chest of the researcher who stopped Chen Xin shows that he is a level 3 researcher. According to the researcher level in the base, he obviously can''t directly deliver his ideas to Chen Xin.


    After all, there are so many people in the whole research base. Everyone has new ideas and passes them to Chen Xin, so he can''t do anything else.


    Therefore, the scientific researchers and technicians participating in the South Tianmen project are divided into five levels. People at each level have different permissions. Level five is the lowest and level one is the highest.


    The third level belongs to the middle level, which can lead a research team composed of level 4 and level 5 personnel to complete the research tasks assigned by level 1 or level 2 personnel.


    Of course, they can also do some of their own projects, but this must be on the premise of completing the work, and these projects must be related to the major projects studied by their departments.


    In short, you can make some inventions by yourself, but your inventions must be related to the projects of your department, and you must finish your own work before you make inventions.


    Therefore, according to the regulations, a three-level personnel obviously has no authority to directly find Chen Xin, not to mention what design scheme he brought.


    The correct process should be that he submits the design scheme to his boss, who thinks it is feasible or has good ideas and ideas, and then reports it to him.


    Level II personnel have the authority to directly submit reports to Chen Xin, but these reports will still be reviewed by Xiyao. If they are not too important, Xiyao will directly give a reply after reassessment and will not reach Chen Xin.


    As for level-1 personnel, their reports will also be reviewed by Xiyao, but their reports will be reminded by Xiyao to review Chen Xin to ensure that he can see them.


    Because the first-class personnel are basically the direct person in charge of each project, the report they submit is related to the project R & D Progress of the whole plan. Chen Xin must read it to ensure his mastery of the whole Nantianmen plan.


    Although level 3 and below personnel are not qualified to report directly to Chen Xin, they can submit the report to Xi Yao and apply to her to transfer the report to Chen Xin.


    As long as they pass the review of Xiyao, Chen Xin can still see their reports, although most of them will be called back and handed over to their superiors for processing.


    Under such a management system, some people report beyond their level, especially the paper documents are sent directly to Chen Xin, which makes things very interesting.


    "My name is white. I''m a scientific researcher in English airlines. I''m assigned to the ''R & D Department of matrix control technology for large variable cycle engine'', mainly responsible for the R & D of engine." the researcher introduced himself and pointed to the report held by Chen novice "I have an idea about the space-based aircraft platform. I think instead of developing new aircraft, why not transform the existing land-based ship? The land-based ship itself can fly. We just need to improve its engine and aerodynamic shape..."


    White got excited and danced.


    However, without waiting for his detailed introduction, Chen Xin interrupted him: "Mr. White, I understand what you mean, but this is not the reason why you report beyond your level? Why don''t you submit this report to your superior or Xiyao?"


    "Sorry, sir, I think you should like to see it very much!" white seemed to have never thought that Chen Xin would have such an attitude. He was at a loss to explain to Chen Xin: "Sir, my design is based on the existing land ships in Yanguo.


    Although I don''t have relevant technical parameters, I sat on a land ship when I came here. According to the parameters of the ship, my team and I designed this scheme.


    I submitted this design scheme to my superior before, but he called back my scheme and told me not to do this, and the artificial intelligence also called back my scheme. It thinks the feasibility of my design scheme is too low! I have to come to you. I think you will find the advantages of this scheme! "


    Listening to White''s words, Chen Xin still didn''t read the design scheme regarded as a treasure by white. Instead, he frowned and shouted to one side, "Xiyao."


    "Academician." Xiyao''s projection appeared.


    Although she is only an artificial intelligence, Xiyao can monitor everything in the base through cameras all over the base.


    As for her projection, it was projected through Chen novice''s watch.


    "Do you know about this design scheme?" Chen Xin motioned to Xiyao the design scheme in his hand.


    "I know that this design scheme lacks the specific performance parameters of the land ship, only stays in the assumption stage, and the feasibility evaluation is only 13.2%, so I call back the scheme and ask for further improvement, but it is obvious that researcher white III has not improved the scheme." Xiyao uses the nano molecule projection scanner through Chen novice''s watch, In just a few seconds, he scanned the design scheme on Chen novice again and gave a low evaluation.


    Hearing Xiyao''s comments, white became more excited. He shouted at Xiyao''s projection: "you''re just a stupid artificial intelligence. How can you understand the subtlety of my design scheme?


    It is much more practical to transform a spaceship with a land-based ship than to study a carrier platform! We should give up any large space-based strategic carrier platform and focus on the line of transforming a land-based ship into a spaceship!


    My design scheme is 100 times more practical than the current plan of the carrier platform which wastes time and resources! "


    Then white looked at Chen Xin excitedly. He seemed to hope for his support and said sincerely to him, "Sir, you must be able to understand my idea and see the essence of this design scheme!


    Land going ships and spaceships, this is what we should study, not to engage in a carrier platform still floating in the atmosphere. That is a useless plan in addition to wasting resources and time! "


    Looking at the excited white and his attitude of trying to impose his ideas on others, Chen Xin couldn''t help shaking his head and returned the plan to him: "sorry, Mr. White, if your plan Xiyao evaluates that the feasibility is too low, then the answer I give you is the same. You''d better go back and modify and improve this plan."


    With that, Chen Xin turned and left. Just after taking a few steps, he looked back at the dull white standing in place and added to him: "by the way, please don''t skip the level next time. It''s very bad."

 Chapter 858

    For White''s plan itself, Chen Xin actually has no exclusion.


    It has long been a cooperative project between Chen Xin and the space Department of Yanguo to transform land-based ships into spacecraft and break through the atmosphere to the universe.


    Prior to the start of the South Tianmen program, the space Department of Yanguo had obtained a specially modified spacecraft from Chen Xin, regrouped astronauts and resumed space activities.


    Therefore, the transformation scheme proposed by white actually has ready-made examples for Chen Xin.


    In terms of feasibility, it is indeed easier to upgrade a land ship into a spaceship than the current South Tianmen plan.


    As for White''s transformation plan, Chen Xin also called out the electronic archive record through Xiyao and browsed it again.


    It has to be said that Mr. White still has some talents. Without nuclear technology, anti gravity technology and many key data of land ships, the transformation scheme proposed by him still has the feasibility of more than 13.2%, which is enough to prove that the whole scheme does have certain feasibility.


    His superior directly called back his plan, which had to be said to be a little rough.


    So Chen Xin also found his superior and asked about the specific related matters.


    But in addition, Chen Xin did not deal with the superior, nor did he express any views on white''s transformation plan.


    As Mr. White thought, Chen Xin did not recognize heroes with his insight, deal with him, get an unfair boss, promote and appoint him, and let him give full play to his talents.


    Chen Xin did nothing, and the justice Mr. White expected did not come.


    From White''s point of view, he may have suffered unfair treatment, but his superiors did nothing wrong.


    All participants of the whole Nantianmen plan serve the plan and project. It is impossible for someone to stop the project that has invested so many resources because he thinks the project and plan are unreasonable.


    Moreover, the primary task of every staff participating in the South Tianmen plan is to complete the assigned project tasks, followed by others.


    As a scientific researcher in the South Tianmen plan and the leader of the project team with three levels of authority, white not only did his own private work, but also led his project team to do private work together. His superior just beat back his design scheme and asked him not to do private work, which has been a shield for him.


    In this regard, Chen Xin reviewed Xiyao''s monitoring records, and there is sufficient evidence to prove that white and his project team completed his design scheme during working hours, which has seriously violated the rules and regulations he needs to abide by.


    After that, Xiyao called back his plan and asked for continuous improvement, which is also no problem. After all, there is only 13.2% feasible plan, and the audit procedure of artificial intelligence can not pass anyway.


    He should at least improve the feasibility of his scheme to more than 30%, otherwise anyone who has any ideas and ideas will report to Chen Xin. He doesn''t have time to do business. Just reviewing these reports every day will make him have no time to sleep.


    In fact, white is not the only one with ideas like this. Many people are very confident in their ideas and designs. They are also reporting their ideas and designs, but others are following the rules and procedures.


    Even if they were called back, they also came back after modifying the scheme. Many people''s schemes passed the review of Xiyao and were seen by Chen Xin after they were changed in this way.


    Chen Xin remembers that in Xiyao''s records, a design scheme was even called back 27 times, but people didn''t come to Chen Xin directly, but seriously revised their scheme again and again.


    This is the correct approach. After all, the rules and regulations are formulated for people to abide by. If you think it is unreasonable, you can suggest modifying the rules and regulations instead of violating it.


    Otherwise, everyone thinks the rules and regulations are unreasonable and everyone violates them. What else should we do with the rules and regulations?


    That''s why Chen Xin called back without even looking at White''s plan.


    Even according to the regulations, Chen Xin can severely punish white, not just let his superiors warn him.


    According to the regulations, Chen Xin can reduce his authority from level 3 to level 5 at the bottom, or directly dismiss him and let someone throw him back where he came from.


    Chen Xin is a person who likes to obey the rules. If the rules are unreasonable, you can modify the rules. If the rules make you suffer injustice, you can appeal, but injustice and grievance are not the reason for you to violate the rules.


    Order and peace are brought about by the constraints of various rules. If you lose the constraints of rules, you can only bring disaster.


    For Chen Xin, he has already seen too much. Especially in this eschatological world, if he loses the rules, it will really be hell.


    So it seems like a small thing, but it can''t be handled as a small thing.


    For white himself, Chen Xin will not impose additional punishment. After all, it is only a small matter in general. Let his superiors warn him.


    But in this matter itself, Chen Xin asked Xiyao to inform everyone, and indicated the possible severe punishment, so that everyone could understand the seriousness of this matter.


    In a sense, Chen Xin is killing chickens and monkeys, but he didn''t take white out to kill him.


    Chen Xin''s handling of this matter is undoubtedly a deterrent to the participants of the whole Nantianmen plan. The vast majority of people did not expect that a leapfrog report would bring Chen Xin such a violent action.


    For a while, many people in the research base had some ideas.


    Some people think that Chen Xin is making a mountain out of a molehill, and some think that he is restricting others'' freedom of speech, but most people still think that Chen Xin is right.


    Xiyao secretly collected and investigated the sources of these remarks and found that most of those who think Chen Xin makes a mountain out of a molehill and restricts freedom of speech come from European countries, and those who think Chen Xin is right are basically Chinese and some lucians.


    Chen Xin doesn''t care about this result, even if those people have opinions or ideas, he also doesn''t care.


    In his opinion, all he wants is for these people to work hard and abide by the existing regulations so that the South Tianmen plan can be completed smoothly. As for other things, it is not within Chen Xin''s consideration.


    It doesn''t matter what these people think or do. They don''t care as long as they don''t violate the regulations and affect the project progress.


    But if someone takes any action, the handling method set by Chen Xin in Xiyao program will definitely let them clearly realize where their mistakes are.

 Chapter 859

    Because of Chen Xin''s handling method, many people have some ideas and opinions, but most people don''t care too much about it. Even if they have opinions, they just complain or complain and don''t make any substantive actions.


    But some people are obviously not so self-discipline.


    Before the disaster, there were great differences between Yanguo and European countries. Yanguo people paid more attention to rules and order and were more willing to abide by various rules and regulations. Few people would put their will above the collective.


    But in Europe, these people seem to care more about the so-called "free will", and they are not willing to obey the collective management and constraints.


    This can be seen from the response of countries to disasters before the disaster.


    Yanguo can well restrain its people, let everyone respond to disasters in accordance with official measures, build a large number of shelters, and maintain social order.


    But in Europe, even the meteorite hasn''t fallen, but there is news flowing out, which has completely collapsed the social order of some countries.


    For these Europeans, even if they want to starve to death, even if the country wants to be destroyed, even if other people want to die, don''t want to restrict my freedom. Nothing is higher than personal freedom. Only free will is what they care about most, and others can stand aside.


    This idea existed before the disaster and had a far-reaching impact on Europe. Even the disaster failed to make Europeans reverse their concept of free will.


    They think that they are more important than the collective. First, they should ensure their own freedom, and second, they should consider the problems of the collective.


    Chen Xin''s handling of this issue has made some researchers from Europe feel that their freedom has been restricted and affected.


    Of course, they were dissatisfied with this situation, so a small number of people connected, and even sent representatives to find white.


    "What do you want to do?" white didn''t have a good attitude towards people who came to him in private.


    Perhaps hurt by Chen Xin''s attitude, white seems very decadent these days. If the base doesn''t provide wine, he may have become an alcoholic now.


    The people who came to him didn''t care about White''s attitude, or white''s resentful attitude, which was what they wanted: "white, can I call you that? Are you really willing to be treated like this by those inflammatory people?"


    "What can you do if you are unwilling? Is there any way you can change all this? This is the military base of Yanguo, and everyone has to work for them!" white looked at the people who came to him with dissatisfaction, but he was not as angry as the other party expected.


    White is really dissatisfied with Chen Xin''s attitude towards him and feels very angry after being warned by his superiors, but he himself is a person with weak self-esteem and even has some tendency of inferiority.


    After all this, he is also reflecting on whether he has made a mistake, but it is usually difficult for people to recognize their mistakes.


    Therefore, white''s reflection has not produced any results, but made him less cynical.


    "But it shouldn''t be! Their banner is the joint research of various countries, but now we are all working for the Yanguo people! They can decide everything, and we don''t even have a chance to speak, which is wrong!" the people who came to white seemed to have some eloquence and motivation. He whispered to white: "Yanguo people are really powerful. They have an advantage in this plan. It''s no problem, but we shouldn''t have the right to speak! For example, the person in charge of Yanguo made a decision alone without even convening any meeting to discuss your matter this time!


    This is dictatorship! This is wrong! We should unite to protest and strive for our due rights and interests! We should implement democratic elections and select suitable candidates to represent our interests. Someone should speak for us and not let all things be decided by the Chinese people!


    Just like what happened to you this time, if someone can stand up for you and fight for you in front of the person in charge of the country, will your design scheme be called back?


    No, not only not, but even if someone fights for you, you can get a new project and become the person in charge of the project!


    It''s not like now. Some hard work is wasted by indifference! All this is because no one speaks for you and no one protects your interests! "


    The people who came to white explained their demands to white. In short, they felt that the whole South Tianmen plan should not be in the hands of Yanguo people.


    Since it is a joint research project, a committee should be elected to discuss and decide all kinds of things together, rather than being decided by the people of Japan.


    It is hard to say that such remarks are wrong. Seeking the right to speak and safeguarding the interests of themselves and small groups is not a wrong thing, nor is it a violation of law and discipline.


    After all, many times, it is difficult for vulnerable groups to safeguard their rights and interests if they can not speak for themselves.


    Researchers from European countries like them can''t express some demands if no one can speak for them, which is not a good thing for the research progress of the whole project to some extent.


    Reasonable expression of demands is conducive to improving work efficiency, but obviously the person who came to white didn''t think so reasonable expression of demands.


    But white obviously didn''t see this, but was stirred up by the other party''s words.


    Yes, I''m just because no one speaks for me this time? If their superiors were on their side from the beginning, willing to speak for themselves, and even support themselves and help themselves improve the design scheme from the beginning, things would not be like this!


    White wanted to "understand", so he asked the man, "what do you want to do? What do you want me to do?"


    Seeing that white said this, the man immediately said to him with some excitement: "we hope white, you can stand up and tell us what you have suffered and the unfair treatment you have received, so that more people realize that we need to unite and strive for our interests from the Chinese people!


    We can''t be a mess. We should elect a person who can represent our interests and speak for us, and spare no effort to support him! Only in this way can we strive for our due rights and interests! "


    At first glance, these words naturally have no problem, and even feel very reasonable, so white was soon convinced, nodded to the man and said, "I see. What should I do?"

 Chapter 860

    When the people who came to white were excited and white planned how he would stand up and speak out about the unfair treatment he suffered and how to win more sympathy, Chen Xin and the heads of major project teams were watching the live broadcast broadcast broadcast by Xiyao in a conference room.


    The heads of these large project teams are not all Yanguo scientists. Although most of them are Yanguo people, there are still several experts from European countries and several experts from Lucia.


    In this base, relying on monitoring probes everywhere and the electronic ID card on everyone, Xiyao can monitor everyone''s every move.


    Although in a sense, this is a violation of personal privacy, or in a more "free" way, it is called a violation of human rights.


    However, considering the very important and highly confidential project research being carried out in the base, all countries agreed to let AI monitor everyone''s decision from the beginning.


    Heads of the major project teams and some important experts know this, and it''s not strange to install monitoring in the laboratory, so no one opposes it.


    Looking at the live broadcast on the screen, an expert from Europe took off his glasses, helplessly pinched the bridge of his nose, sighed and said, "what are these people thinking? When are they still thinking of competing for power and profit?"


    As a real scientist, he clearly understands why countries should invest so much resources and energy to promote the South Tianmen project and the situation facing mankind.


    It can be said that if mankind does not unite and work together in good faith, it is hard for Yanguo and Lucia to say that European countries will surely come to an end.


    Now, European countries can continue to maintain the European defense line and have the spare power to improve people''s living conditions. To a large extent, they rely on the assistance of other countries.


    Therefore, the whole Nantianmen plan is dominated by Yanguo, and Yanguo has no problem in mastering the right to speak, because this is the case now.


    Even if European countries unite and count Lucia together, they can''t compare with China in strength.


    If not for the inflamed countries, they still need European countries to resist the invasion of alien organisms, they can leave Europe alone and let Europe live and die.


    It is precisely because of this that European countries have no intention to compete for any voice with Yanguo now, not to mention the whole South Tianmen plan. Yanguo actually only needs these European researchers to work, not their opinions.


    Therefore, after Chen Xin convened the heads of various major project teams to watch the live broadcast of how these people are preparing to do things privately, everyone''s attitude is actually very unified.


    "These guys! How many of them? Since they don''t want to work well, let''s just send them all back to Europe!" an expert from Lucia seems to be grumpy and wants to do it once and for all.


    His proposal has won the support of many people. These experts are real scientists. They all hate this kind of thing that they don''t do real academic research and work.


    However, some people have put forward relatively mild suggestions: "I don''t think we should use such fierce means. Many people are just incited. We can be a little lenient to them and only deal with those who are the first. Now the research of various projects is at a critical juncture. If a large number of people are suddenly sent away, it will affect the research progress."


    Hearing someone say so, others nodded in agreement.


    After all, they are in charge of a large project. I know that the manpower is tight and the project progress is really a critical moment. If there are a lot less people, or even suddenly people are panic, it will really affect the project progress.


    "Chen, what do you think of this?" a Lucia expert asked Chen Xin.


    As the general director of the whole Nantianmen plan, Chen Xin certainly has the final decision to kill and seize these people.


    So everyone looked at Chen Xin and waited for his decision.


    However, to everyone''s surprise, Chen Xin just touched his chin and said, "let them make trouble, and deal with it when things get noisy."


    "Academician Chen, this will affect the progress of the project." an expert from Yanguo reminded Chen Xin.


    Chen Xin nodded and didn''t deny it, but he still said, "because some people were dissatisfied with white''s incident before, which itself has affected the progress of the project."


    With Chen Xin''s words, Xiyao also timely projected various statistical data to let everyone in the conference room see the specific affected progress.


    "The resentment of these people will affect the progress of the project. Instead of letting them hold back or let us deal with the hidden dangers directly, we''d better take this opportunity to let them make trouble, let everyone vent their emotions, expose the hidden problems, and then solve them at one time." Chen Xin still has an indifferent attitude, but his treatment method seems very cold: "I don''t like to leave future troubles. If I want to deal with the problem, I''ll just cut the grass and root out the problem elements, and then clean them up at one time, so that other talents can work more at ease."


    Hearing what Chen Xin said, although everyone thought that doing so would interfere with the project progress, it was really bad to keep hidden dangers all the time, so after discussion, everyone supported Chen Xin''s decision.


    At this time, white, who is monitored by Xiyao, has also discussed their plan. They plan to find a lunch time, and white will talk about the unfair treatment he has suffered in the canteen, and then others who have already connected in advance will coax and incite others, and then put forward their demands and negotiate with the threat of strike, Let the Japanese side agree to their demands.


    Generally speaking, these people really planned and calculated very orderly. If Chen Xin hadn''t found out about it in advance, their plan would have a great possibility of... Failure.


    Because these people have made a mistake, that is, it is not Yanguo asking them to work.


    If they don''t work, Chen Xin can send them back to Europe for a group of people who are willing to work.


    In fact, if the whole South Tianmen plan is not to integrate the science and technology and resources of various countries, Chen Xin can complete the plan by himself without the participation of European countries.


    As for these Europeans, they may indeed make trouble, but it is clear that as long as they make trouble, Chen Xin can catch them all, load them on land ships and send them back to Europe.

 Chapter 861

    Things developed as Chen Xin expected.


    At noon after two days, white delivered a speech in the canteen accusing him of all kinds of unfair treatment.


    Those who contacted him before also took the opportunity to coax in the crowd, and began to spread discontent, incite others to sympathize with white, and try to get more people to join the protest.


    However, just when they thought everything was going well, white''s speech attracted a lot of people to watch, and they also started the people who had been connected in advance, a team of soldiers equipped with heavy mecha suddenly burst into the canteen.


    These heavy machine armor are not as common as power armor.


    They are more than three meters tall, have much heavier armor than power armor, and are also equipped with heavier weapons.


    For example, machine guns and missile launching nests can be seen on Titan, as well as portable guns and other weapons.


    This heavy machine armor was originally designed to replace tanks and form a new armored force with infantry equipped with power armor to deal with obstacles such as barricades or strongholds that may appear in urban street warfare.


    At first, this kind of heavy machine armor was very popular with the military. They directly changed to an armored division.


    However, with the emergence of Titan, the positioning of heavy mecha seemed to be on the same level.


    As an individual equipment, it is too large and heavy, not as light and flexible as power armor; As a vehicle, the equipment is not as solid and reliable as that of Titan. It is inferior in both firepower and defense.


    Originally, as heavy individual equipment or light vehicles, this heavy machine armor is not useless.


    However, with the invasion of alien creatures, the army needs more heavy firepower such as Titan. If a single soldier has power, armor is enough, and heavy machine armor has no large-scale equipment.


    Even so, the military still armed one or two armored divisions and sent them to the battlefield during the previous battle of Dongting Lake.


    The deterrent power of this heavy machine armor is not comparable to that of power armor. Its height of more than three meters is equivalent to the firepower configuration of light vehicles, which makes these big guys know that it is a real war machine at a glance.


    In the face of power armor, maybe people who are not afraid of death stand up and bet whether a soldier will shoot.


    But in the face of such guys with guns, no one dares to stand in front of them, let alone talk to these war machines about freedom and democracy.


    "Catch all the people whose ID cards turn red." with these heavy machine armor and another team of soldiers equipped with exoskeletons, as soon as they entered the field, they checked everyone''s ID cards according to the order of the team leader. They caught all the people whose color turned red and locked.


    Obviously, these people whose permissions are locked are the people who are connected in advance marked by Xiyao.


    Because of the deterrence of heavy machine armour, no one dared to stab or protest at this time. Even if there was resistance, they were quickly subdued under the suppression of the soldiers and then taken away from the canteen.


    White was so regretful that he was quickly subdued by two soldiers and pressed on the table in the canteen.


    He was supposed to speak from the table, but it was clear that the soldiers would not make him so conspicuous.


    He regretted why he listened to those people and stood up to give a speech. Now he will be thrown back to Europe.


    At the thought of returning to Europe and going to the day when he could only eat three meals and feed on protein, white''s regret could not be expressed in words.


    "It''s a pity, Mr. White. I should have asked your superior to warn and remind you not to violate the regulations again. It seems that you didn''t listen at all!" Chen Xin came to the canteen after the situation was controlled. Looking at white pressed on the table, he couldn''t help sighing.


    For white, Chen Xin really doesn''t have a bad feeling. Although he hates his violation of the rules, he doesn''t intend to do anything with him.


    However, some people always kill themselves and live a good life. However, they have to make something happen.


    "Sir, please give me a chance!" white begged Chen Xin. Now he finally knew he regretted and knew that he had done wrong: "I know it was wrong. Please don''t send me back to Europe!"


    "Sorry, Mr. White, I''ve given you a chance. You didn''t cherish it yourself." Chen Xin shook his head and said to the soldiers escorting white: "pull it out, ship it with others, and then send it back to Europe."


    With that, Chen Xin looked at some unknown people in the canteen, so it seemed that they were frightened. After thinking about it, he stepped on the chair and stood on the table.


    After asking Xiyao to connect her voice to the speaker of the canteen, Chen Xin said, "sorry to interrupt your lunch time. Before, some people with ulterior motives intended to take this opportunity to incite a strike and undermine the project research of the South Tianmen plan, so as to achieve their selfish purpose.


    Their plot was discovered by Xiyao in time and reported to me, so I transferred the garrison of the base to arrest them, and then they will be deprived of all authority and repatriated.


    I hope you will not be affected by them. The South Tianmen project is a multinational joint research project jointly negotiated and adopted by all countries. There is no matter that you are working for the country or that you are being squeezed by the country.


    This research concerns all mankind. Your work is to integrate the science and technology and resources of various countries and contribute to the survival and development of all mankind. Everyone should do their best to work hard, not to affect the progress of the project for the so-called freedom, democracy, the difference between countries, and meaningless personal ambition.


    This time, we only dealt with the leading saboteurs and only repatriated them. However, if anyone wants to emulate them, I will investigate his responsibility next time, not only will he be repatriated, but also impose penalties including but not limited to imprisonment according to the seriousness of the circumstances.


    I hope you will understand that the South Tianmen plan was adopted by agreement of various countries. The government of your country has granted the planning committee full powers. We have the right to investigate and punish those who affect the progress of the project. Therefore, please take your work seriously in the future. "


    Chen Xin said that and left the canteen.


    As he left, the team of heavy mecha also lined up behind him.


    Looking at Chen Xin leaving under the protection of heavy mecha, everyone in the canteen was silent for a moment.

 Chapter 862

    Those who intended to make trouble were sent back to Europe by land ships that day, and it would not be good to wait for their fate.


    After all, all countries have participated in the joint research of the South Tianmen project, and the official institutions of European countries have also expressed strong support for it, and these people sent back are undoubtedly a great shame to the official institutions of all countries.


    Even if Chen Xin did not hold them accountable, the official institutions of their country would hold them accountable after they were sent home.


    But this has nothing to do with the base and the South Tianmen plan.


    After those people were sent away, the atmosphere in the base was indeed tense for some time, but the appeasement and restraint of the heads of major project teams did not cause irreparable consequences.


    After the aftermath of this incident, the researchers involved in the South Tianmen project obviously focused more on their work, so the project progress was improved.


    In addition to these troublemakers being dealt with and repatriated, this matter also has another impact.


    It was their proposal to elect some public opinion representatives to respond to problems at the upper level and speak for the lower level. After discussion between Chen Xin and other responsible persons, it was approved.


    However, instead of playing with public opinion elections, Chen Xin Let Xiyao open the permission of lower level personnel to respond to her.


    Everyone can respond to problems or put forward opinions to Xiyao, who will screen and evaluate and make treatment decisions.


    These handling decisions will be fed back to the parties and their superiors by Xiyao, and the more important things will go back to Chen Xin, so as to form an effective public opinion feedback mechanism.


    After the opening of this mechanism, less than 1% of the remaining parts can be fed back to Chen Xin.


    Even for this 1%, Xiyao has attached handling opinions. Chen Xin only needs to read it once and make some modifications if he thinks there are problems, so he can give a direct reply.


    After this mechanism has been put into operation, the satisfaction of all staff has indeed increased a lot, and the work efficiency has also improved.


    On the whole, this matter has a fairly satisfactory result.


    Seeing that this matter had a satisfactory result, Chen Xin stopped paying attention to it.


    Because after a week of uninterrupted flight, the small airborne aircraft platform for testing has successfully completed the test mission and landed on the runway of the base again.


    In the course of this week''s test, the small airborne aircraft platform used for the test had various problems, and the most serious one even caused the strike of one of the engines.


    However, relying on the anti gravity generator to stabilize the fuselage at the flight altitude, a brave crew climbed out of the fuselage for maintenance outside the cabin, and the fault was successfully eliminated.


    This also reminds the project team that a maintenance channel needs to be set outside the carrier platform.


    After all, when a long-term non landing flight needs repair and maintenance, it really needs an external channel that can be used for external maintenance.


    In addition, there are other problems reflected by this test, some of which have been successfully solved by the crew, some require overhaul and maintenance after the landing of the carrier platform, and some simply need to be removed and rebuilt.


    Fortunately, all these were expected by the project team. In the final analysis, this is only the first test flight of a technical verification aircraft. It is normal to have problems, and it is strange not to have problems.


    When the problems are exposed, they naturally need to be dealt with. Both Chen Xin and the project team obviously put their energy and time on it, and no one cares about the public opinion.


    There are many problems exposed in the flight test of small airborne aircraft platform. After all, it was a hodgepodge at the beginning.


    Although the technologies are mature and have no problems flying, the running in between various technologies is not very good.


    The problems in this flight test are mainly focused on this aspect.


    The project team can only study how to solve this problem one by one. There is no shortcut.


    Although for Chen Xin, that is, the system is upgraded once, the reason has been said that in order to integrate the technologies of various countries, Chen Xin does not intend to use the system upgrade to hang up.


    The cost of Chen Xin''s failure is that the project team spent about four months to successfully solve all the problems exposed in the flight test of the small carrier platform.


    In these four months, other project teams have also made a lot of progress.


    For example, the research team of the energy shield project solved the problem when Chen Xin gave a topic on how to make the shield not hinder the use of weapons in the shield.


    The way to solve the problem is also very simple. The project research team has come up with two different schemes.


    Scheme 1 is to make the shield into a shield and use it like the shield in the cold weapon era. Naturally, the shield will not affect the use of weapons.


    This solves the problem, and it is not difficult to realize it. Even there is no need to make any change to the existing shield use form. It only needs to change the original 360 ¡ã fully activated shield into a small area shield only for the attack direction.


    To achieve this, only some adjustments need to be made to the magnetic restraint and radar.


    The radar accurately judges the attack direction, and the magnetic restraint device activates the shield in this direction to play a defensive role.


    However, there are some problems with such a shield, that is, it will be easy to resist small power attacks, but if it is a high-power attack, it will cause damage beyond the coverage of the shield.


    Of course, this problem is not serious. After all, the shield can pop up the explosion or fragments. Even if there is a place beyond the shelter, it will not be seriously hurt.


    In addition, you can also increase the output of the shield generator, expand the coverage area of the shield, or simply activate the full coverage shield, which can make the defense watertight.


    As for the other method, the idea is more strange. They adopted an idea in science fiction to stick the shield on the surface of the object that needs to be protected.

 Chapter 863

    Because the charged particles are constrained by magnetism to form a shield, the shield itself has no specific shape. It can be a ball or made into other shapes.


    So they simply gave up the spherical shield, and the falling shield adhered to the surface of the equipment and made it attached to the surface of the equipment. In this way, they can not only continue to play a defensive role, but also keep the weapons undisturbed.


    However, this has high requirements for magnetic confinement technology. So far, they have not been able to make the magnetic field evenly distributed on the object surface, and are still carrying out technical research.


    However, based on the existing magnetic constraint technology, it is difficult to find a magnetic field that can fit the surface of the object, not impossible. Therefore, Chen Xin still did not intervene, but let the research group carry out technical research by itself.


    In fact, these are not the only two schemes proposed by the project team, but after multi-party comparison, only these two methods are reliable.


    Several other options include shooting with weapons out of the shield; Some people really made a shield and held it in their hands to fight like in the era of cold weapons; The shield was also connected with the machine gun firing coordinator at the machine gun firing port of the propeller aircraft, and the shield was also designed as a coordinator


    These schemes can not be said to be unreasonable or impractical, but they are relatively less practical.


    For example, adding a shield coordinator to pause the shield when firing is a good design idea, but it is not unrealistic.


    Weapons with low firing frequency, such as artillery, may also use this design. Anyway, it doesn''t matter if they flicker every other period of time.


    But if it is a weapon such as a machine gun, the shield will not work at all when the machine gun is fired.


    In modern warfare, a few seconds can determine life and death, not to mention how machine guns can have a few seconds to shoot continuously. During this time period, shields can not play a protective role.


    Therefore, although this scheme is the simplest to implement, just improve the startup of shield generator, it is the most difficult to use among several schemes.


    As for the form of shield, this is a design that can be tried, but it is only suitable for individual equipment or large size for things such as Titans.


    Vehicles such as tanks or aircraft are not suitable for this design of shield.


    In fact, the design of extending the weapon out of the shield is the same. It''s not a problem for you to use it alone. Even tanks can be used together, but it''s really useless for aircraft.


    Modern fighters, especially the fifth generation aircraft, pay attention to stealth performance. The missiles and machine guns on the fuselage are made into hidden type, which is to reduce the reflection area of the surface. They will be exposed only when they are in use. There is no way to stretch out the shield in advance.


    Therefore, the project team finally determined the direction of tackling key problems in two directions: directional shield and irregular shield.


    As for the existing shield, in fact, it can not be used by relying on the principle of coordinator. It has been reflected when the Titan troops were tested before.


    When the shield is not activated, the shield has no impact on the operation. If you want to fire, you can fire with a machine gun, or even a missile. As long as the shield is not activated, there is no problem.


    Only when you are attacked and want to continue the attack when the shield is activated will it be impossible to attack targets outside the shield.


    When the shield has been activated and cannot attack, it is mainly when it is fired by fire or surrounded by melee units.


    Therefore, after some evaluation, the military still installed the shield device on warships, fighters and other vehicles, adding a layer of defense to these vehicles.


    As for the army''s tanks, they are not equipped with shields. Even Titan is equipped with shields only for some new models and upgraded general modifications, which are not fully popularized.


    In addition to the shield project, good progress has also been made in air and space fighters. After the technology has been verified by the technology verification aircraft, the project team has begun to design the prototype aircraft.


    In this regard, all countries participating in the South Tianmen project have shown strong interest. Almost unlimited resources from European countries have been invested in this project. They even dug out the original paper archive materials and packed them and shipped them from Europe to meet the research needs of the aerospace fighter project.


    Because air and space fighters are very valuable projects for all countries.


    This is not only because of the combat effectiveness of the space fighter itself, but also because it represents the possibility that the aircraft can break through the atmosphere and enter outer space.


    The realization of this actually represents another meaning, that is, the cheap way to enter space.


    The fundamental reason why human beings do not explore outer space on a large scale is not that technology cannot do it, but that there is no cheap technology.


    Sending a man into outer space costs far more money than gold as heavy as himself. One can imagine how much money a space project needs to invest.


    So far, only the three blue star top powers and powers, Yanguo, Lucia and the Federation, which no longer exist, can afford the manned space program.


    Although Europe can also play space projects, it can carry out manned space independently. Even if European countries unite, they can''t do it. They can only send their astronauts into space with the help of federal technology.


    The international space station is also a multinational cooperation project, and even the federal government can''t afford to play it.


    What countries have been seeking and exploring before the disaster is cheap and reusable space technology.


    If we can make a breakthrough in this, then mankind can step out of the blue star, the cradle of human civilization, enter the vast space and open a new era of human civilization.


    Compared with the harsh natural environment and limited resources on the blue star, the vast and almost unlimited resources of the universe are the hope of human development in the future.


    Therefore, all countries are very interested in the aerospace fighter project. They hope to make a breakthrough in this technology, and then commercialize it, restart space activities, or simply establish a space city in outer space, and human beings migrate to outer space or colonize the moon.


    In this regard, Chen Xin did not make any impact or interference, nor did he upgrade the system for the project, but just watched the research of the project team.


    This is not that Chen Xin is not enthusiastic about it, but that he clearly remembers that there is a clear limitation on the system he obtained, that is, after he leaves the doomsday environment, the system will be frozen.

 Chapter 864

    The continuous promotion of the South Tianmen plan has greatly influenced and promoted Europe, Lucia and even the mainland of China.


    As we all know, if you want to quickly settle and solve the problems of victims after a major disaster, carrying out engineering construction and providing work for relief is the most effective method.


    In addition to various scientific research projects, the South Tianmen plan also requires a lot of resource investment and industrial production capacity for the production of industrial raw materials and various parts required by the project, which undoubtedly stimulates the depressed social situation of various countries.


    For European countries, the industrial production demand brought by the South Tianmen plan has greatly stimulated their domestic economic recovery.


    The South Tianmen plan itself has the purpose of integrating various industries such as industrial systems and production resources of various countries. Therefore, after receiving their share to meet, all countries are actively promoting the recovery of their own industrial system.


    Originally, Chen Xin had adopted a series of measures in Europe to make European countries recover, which can be regarded as a basis for recovery.


    Now, stimulated by a large number of order demand, countries have invested a lot of human and material resources to expand these foundations into a new industrial system.


    As long as their original industrial system is well preserved and can resume construction, they also actively began to resume construction under the intervention of official institutions of various countries.


    Although the expansion and recovery speed is not too fast because of the relationship between time and resources, it has also greatly solved the current employment and various social and livelihood problems in various countries.


    Even some original industrial cities have a labor shortage due to the sharp decline in population after the disaster, so that they have to find ways to obtain labor from other non industrial cities.


    The reactivated industrial production undoubtedly found a way for most survivors who had to struggle because they had no jobs and other sources of income.


    Although Chen Xin''s previous initiatives in Europe have improved the living environment in Europe, many people have been able to live.


    However, the things that Chen Xin made essentially serve the war on the front line. Materials have to be transported to the front line. Even people have to join the knights to pay blood tax. For many survivors, the improvement is not as great as expected.


    The increased supply of goods and materials is only to make them from three meals to three and a half meals.


    After all, countries will not feed these people in vain. Keeping them hungry is the limit of assistance by official institutions of various countries. More materials are still supplied to the front line of defense.


    However, the recovery of industrial production is completely different. Workers can get paid through work, which not only enables them to eat and wear three meals, but also enables them to have a certain balance and improve their quality of life, so as not to live as embarrassed and miserable as before.


    As for their salary, in addition to synthetic protein blocks as food for three meals, there will also be some necessary living materials and tokens that can be used to buy industrial products.


    Originally, European countries wanted to continue to use the euro, but obviously Europe is now like this. The credit of countries is not as good as paper, and the euro is also too hard to wipe its ass.


    Therefore, with the help of Lucia, countries simply used the leftover materials from industrial production to make tokens with stamping machines to replace money.


    Although some clever people soon thought of ways to obtain a large number of tokens by counterfeiting, it is a pity that in this social environment, power, resources and equipment are controlled and difficult to obtain, and counterfeiting is too easy to be found.


    Therefore, generally speaking, there is no big problem in the issuance and use of tokens.


    With such measures, the situation in European countries has gradually begun to improve.


    The factory re issued the roar of machinery, and the city gradually regained the breath of life.


    This is also a good thing for the South Tianmen plan. The recovery of the situation in European countries will bring increased industrial output and resource output. Various resources required by the South Tianmen plan are mined and processed into raw materials.


    Some raw materials will be further processed into various parts, more advanced synthetic raw materials, or directly made into industrial finished products, and then continuously transported to Yanguo or other countries together with other raw materials for the research and production of the South Tianmen plan.


    Stimulated by this whole process, a new industrial chain has been formed.


    On the other hand, Yanguo has not suffered losses. Although Yanguo obtains these raw materials and industrial products from European countries without compensation, it still needs to provide remuneration to countries.


    However, most of these rewards are food and basic living materials, which are produced by using these raw materials to a large extent.


    For Yanguo, although it seems that Yanguo is supporting European countries, on the whole, Yanguo does not suffer losses. On the contrary, it better supports the promotion of the South Tianmen plan by relying on the increased industrial capacity of European countries.


    After all, even with the strength of Yanguo before the disaster, it is almost impossible to support the South Tianmen plan.


    Moreover, without the participation of European countries, many unique technologies of European countries can not be used to supply various projects of the South Tianmen plan. The participation of researchers from various countries also makes the research progress of the project much higher than that of China alone.


    Therefore, overall, the South Tianmen plan is still a win-win situation.


    Even the railway and other transportation lines from Europe to Yanguo have been touched with light, and many cities that need to pass or stay on each transportation line have been restored because of the reopening of transportation.


    The opening of the transportation line itself has also strengthened the material exchange and circulation between Europe, Lucia and Indonesia, so that the exchanges among countries are gradually restored, and there is a trend for human society to become a whole again.


    This is exactly what countries want.


    Before the disaster, with the development of science and technology and society, countries all over the world had already become an inseparable whole, and there were countless relationships among countries.


    After all, no country dares to say that it can completely cut off its ties with other countries. Even if it has a complete industrial system, it also needs to import a lot of things from abroad.


    This is especially true for small countries. Many countries are heavily dependent on import and export. Even several developed countries in Europe also need to cooperate with other countries.


    An unprecedented disaster has cut off the links between countries, which has actually dealt a great blow to all countries.


    Now the resumption of ties is a major positive for all countries.

 Chapter 865

    The recovery of industrial production capacity in European countries not only improved the situation in various countries and improved the quality of people''s life, but also had a great impact on the war situation on the front line.


    Originally, the European defense countries only tried their best to support it, and the situation improved only with the support of the United States.


    However, the production capacity of various military equipment provided by Yanguo to Europe is also limited. Even after the domestic war has ended, Yanguo still cannot provide a large number of military equipment and materials to Europe.


    Previously, with Chen Xin''s efforts, the European aid fleet was able to establish a large number of sub bases in Europe, which finally pulled up the production capacity of various military equipment and materials, so as to stably transport equipment and supplies for the front line.


    But this is still not enough to change the war situation, but to stabilize the already precarious defense line, so that Europeans will not continue to retreat and lose their already scarce territory.


    With the recovery of European industrial capacity, countries can produce foreign trade version equipment provided by China, and the situation is very different.


    Although the production capacity of all countries can not be compared with that of Yanguo, even if they add up, it is only equivalent to that of the European aid fleet, it can provide equipment and ammunition for the front-line troops in twice the previous quantity, which undoubtedly enables the front-line troops to complete the dressing change faster.


    Although it is incredible to say, even with the production system built by Chen Xin in Europe for a year, the whole European defense line has not completed all the dressing work so far.


    Although foreign trade powered armor, exoskeleton and electromagnetic rifles are allocated to almost every section of the defense line, many troops still do not get new equipment.


    This is not because the inflamed country has not provided enough weapons and equipment, nor is it because European countries are still playing intrigues and have not distributed enough equipment to all troops.


    But because the defense line is too long and there are too many troops stationed in the defense line to resist the invasion of alien creatures.


    Even if the European aid fleet has been fully produced, before the industrial production capacity of European countries is restored, the number of weapons and equipment produced is still limited and can only be changed to troops in part.


    Considering the combat effectiveness, only elite troops can give priority to obtaining new weapons and equipment.


    In addition, the Knight Order and joint security maintenance force systems developed by Chen Xin ensure that the army can quickly familiarize itself with equipment and form combat effectiveness after changing clothes, but this also leads to the fact that the speed of changing clothes is not so fast.


    The recovery of European industrial production capacity not only enables European countries to start mass production of new weapons and equipment, but also allows the European aid fleet to expand production capacity.


    With 3D printing equipment, for the European aid fleet, the only limit to expanding production capacity is raw materials.


    Relying on these, the soldiers on the front line finally have enough weapons and equipment to make the line truly stable. Even if alien creatures have repeatedly made large-scale attacks, there is no danger to be broken through in the line of defense.


    The stability of the defense line undoubtedly gave European countries a sigh of relief.


    After all, from the initial danger to the occasional sporadic alarm of large-scale attack after receiving the assistance of the inflammatory country, although European countries rationally know that they are not so dangerous, they are still worried that if the defense line is broken one day and alien creatures flock into Europe, everyone will be finished.


    Now the stability of the defense line undoubtedly makes them completely relieved and don''t have to worry about the breach of the defense line.


    This has a great impact on European countries.


    It''s like there is a fence in front of you, and outside the fence is a large group of hungry lions and tigers preparing to eat. If it''s just a wooden fence, you will feel that your life is in danger at any time.


    If you replace the fence with barbed wire, you will know that you are safe, but when those beasts roar and roar at you, or even rush at you, and the barbed wire is deformed, you will still feel cold in your back.


    Only when the fence is replaced with a high wall of reinforced concrete, the lion and tiger can''t jump up at all, and the fence is connected with the power grid, can you feel safe completely. Even if the lion and tiger shout loudly outside, you won''t feel dangerous.


    European countries that feel safe also have more energy to manage their domestic problems.


    Before, I was worried that the defense line would be broken. All countries tried their best to supply and maintain the defense line, and were simply unable to maintain their own national economy and people''s livelihood.


    Now the defense line is stable and less dangerous. Coupled with the recovery of industrial production capacity, countries can finally work hard to improve the national economy and people''s livelihood and carry out post disaster reconstruction.


    However, when countries began to rebuild their own countries after the disaster, they inevitably had some new ideas.


    Especially with the gradual restoration of communication channels between countries and the improvement of information circulation efficiency, they also know that Yanguo has encountered alien biological invasion, but they will eventually eliminate it all.


    Although it is said that the scale of alien biological invasion in Yanguo is not large, and it is not difficult to eliminate it with Yanguo''s national strength, it still gives European countries new ideas.


    They think that since Yanguo can eliminate alien creatures, can they do the same thing?


    Even if not, on the premise of having enough weapons and equipment, can we move forward and recover some areas previously occupied by alien creatures?


    This is not a fantasy. After all, there are examples of Yanguo''s successful elimination of alien creatures at home and abroad. They don''t think it''s impossible.


    As for nuclear weapons, both England and France have nuclear powers, and Lucia is a nuclear power. It is not difficult to get some nuclear weapons that can be cleared.


    The emergence of this idea has had a great impact on European countries. After all, no country does not want to recover the lost land.


    Even Yanguo and Lucia did not stop the Europeans on this matter, but only persuaded them to be cautious and be fully prepared.


    It is best to wait for the success of the South Tianmen plan, the launch of the large-scale Aerospace strategic aircraft platform, and the most secure way to cooperate with the armies of various countries to launch a counter offensive.


    Although European countries feel that this very sound proposal put forward by Yanguo is too sound, they also know that without the support of Yanguo and Lucia, they can not complete the plan of counterattack and recovering lost territory alone.


    Therefore, although European countries have started preparations in this regard, they have not acted impulsively. On the one hand, they are resuming domestic production and construction, on the other hand, they are beginning to accumulate materials and silently prepare for the counter offensive.

 Chapter 866

    The Knights of pine and sleigh are a rural knights in France. When Chen Xin asked the autonomous cities to form the knights, several surrounding cities funded the formation of the Knights.


    As for this somewhat nondescript Knight Order name, it comes from the specialties of several surrounding cities.


    These cities are located in the foothills of the Alps. They are some small cities in the mountains. In the past, they mainly relied on tourists visiting the Alps and some agricultural and sideline products to maintain the city''s financial revenue.


    The local pine and the sleigh made of pine are one of the few local specialties. Therefore, when the knights were named, someone proposed to use this name.


    The number of the knights is not large. About 20 volunteers have been gathered in several surrounding cities, which can be regarded as the first members of the Knights.


    They have obtained a number of fairly decent equipment. In addition, several surrounding cities have brought them some local specialty sleds, and several snow motorcycles provided by members of the order have become all the possessions of the order.


    Because the surrounding cities are small, and the population is small, everyone knows each other, and even relatives, the Knights actually do not have many tasks to maintain law and order.


    They mostly use the snow motorcycles and sleds of the knights to help local residents transport some things, or help local autonomous institutions do some entrusted work, but they are not combat tasks.


    This seems better for the people of the Knights. Many of them are just forest guards or ordinary local residents. They volunteered to join the knights to do something for their hometown.


    No combat mission makes them more comfortable. After all, no one likes war.


    Moreover, if there is a local security problem, they are likely to face their own acquaintances.


    So they are also happy to receive daily jobs such as moving things or helping autonomous institutions repair. In addition to paying blood tax at the front line, they haven''t even fired a gun.


    But this is really not a problem for such a small place. Even some young people with ideals have taken the initiative to join them and become the new blood of the Knights.


    With the recovery of the industrial capacity of European countries, the situation in all countries is picking up, and the small cities where the Knights are located are also stained with some light, making life a lot easier.


    As a result, the Knights lived a lot with their childhood, and the regiment also bought some new possessions.


    For the surrounding towns and knights, such a day can be said to be very good. If they don''t have to send people to pay blood tax, they even think it''s not very different from their previous life.


    That is, it''s a little dark and cold. Although everyone''s life has been a little bitter, they can deal with it now.


    Originally, people thought that life would be like this in the future, but a news spread after a group of members of the Knights returned from paying blood tax.


    "You know, countries are preparing for a big counterattack, and materials are hoarding everywhere! When we were on the front line, the army even tried to recover the lost land of some protrusions!" the knights who had just returned from the front line boasted the gossip they had heard in the local pub while taking advantage of their vacation.


    In the past, the main industry of these small cities was all kinds of agricultural and sideline products, and wine making will naturally happen.


    Although there was no sunshine after the disaster and the grain yield was terrible, after life was better, they still managed to get something that could ferment and brew something that could barely be called wine.


    For most old drinkers, this can only play a comforting role. A little is better than nothing, but it makes the tavern flourish again.


    Everyone likes to come to the pub for a drink, chat and boast with others. It is one of the few recreational activities now.


    So these knights who have just returned from the front naturally like to come to the tavern and boast about their experience on the battlefield.


    This time, however, what they boast is not a face-to-face dance with alien creatures, but the big news that countries intend to turn from defense to counterattack against alien creatures.


    "Really, little Jimmy? Are they really going to fight back against those alien monsters?" an elderly old man asked when he heard the members of the Knights say so.


    This is a bad thing about this small town. Everyone knows each other. Maybe you met an old man who participated in your baptism when you were a child. He watched you soak cold water with your feet and pee a pot by the way.


    Compared with the black history from small to large, being called a nickname is no longer a great thing.


    The member of the Knights called little Jimmy put down his glass and vowed: "Of course it''s true! When we were on the front line, we built several new ammunition depots for the army. They were already hoarding ammunition, and Bob also participated in the counterattack. A line of defense that had been hit out of the protrusion was pulled back by the army. I heard from him that he killed at least 200 alien monsters!"


    "Good job, Bob!" a member of the Knights named Bob was also in the tavern. Little Jimmy''s boast made everyone in the tavern cheer for him.


    For these people staying in the rear, alien creatures are still a little far away from them. After all, people from the enemy occupied areas on the front line are unlikely to come to small cities like them under these conditions.


    So the only thing they know about alien creatures is the dictation of the knights who went to the front to pay blood tax.


    Bob raised his glass and motioned to confirm what little Jimmy said.


    However, even if it is confirmed that countries are indeed preparing to fight back, this kind of thing is still too far away from the residents of small cities. They just discuss it without any practical feeling.


    While their discussion was in full swing, a land ship was landing at the Knights'' station.


    The head of the order and several important members stood in front of the land ship to meet the people on board.


    A logistics official came. Before the Knights paid blood tax, the other party came to pick them up. This time is the same.


    For some procedural reasons, picking up people to pay blood tax and sending back those who have paid blood tax are not carried out by the same land ship, but a ship full of people to send or pick up each Knight order one by one.


    "Pine and sleigh knights, there are four people in the blood tax this time. Get on the boat." the official checked the list and checked the members who paid the blood tax, so they got on the boat.


    The captain of the knight watched them get on the ship and was a little relieved. Paying blood tax can be said to be the most important thing for the knight regiment. If they can send people on the ship smoothly, they will be half done.


    However, there was still a little unexpected this time, because the logistics officer handed a document to the head: "I believe you should have heard the news that countries are preparing to fight back. All Knights need to be prepared. You can see the document for specific requirements."

 Chapter 867

    Such situations as pine and sled knights are almost everywhere in Europe. Each Knights received documents from logistics officers asking them to prepare for future counterattack plans.


    In fact, they don''t have much to prepare. Only one third of the members of each Knights will be recruited, the remaining third will be used as reserve, and the last third will continue to maintain daily operation.


    In other words, since they received this document, at least half of the people of each knight regiment should start military training and be ready to go to the battlefield at any time.


    At the same time, the logistics officer will also issue several sets of exoskeletons to each Knight order to make them familiar with and understand the use of these equipment and be able to use them skillfully.


    According to the requirements of the document, each member of the Knights must be proficient in the use of exoskeleton, and be able to complete a full set of tactical actions in the case of wearing exoskeleton, reaching the qualified standard.


    For knights like the pine and sleigh knights, which usually have no combat tasks, they suffer a lot. They have little military action and little military training.


    Although according to the requirements of the knights, they usually have some shooting training to maintain basic combat effectiveness, they do lack professional military training and lack practical combat experience. Only those members who have paid blood tax have certain combat experience.


    In fact, at this time, European countries were also very glad that Chen Xin had developed the knight order system and blood tax policy, which made them have more troops with at least a certain training foundation and certain battlefield experience.


    You should know that the biggest difference between veterans and recruits is battlefield experience.


    During World War II, when the cannon rang on the battlefield, veterans would listen to the caliber and landing point, hide in the gun hole and count the time when the barrage slowly entered, while the recruits were scared and shouted, said they couldn''t help running around, and then they were directly killed.


    Those members who have paid blood tax on the front line have experienced combat and seen the cruelty of the front line and the appearance of alien creatures, which has laid a good foundation for them.


    They only need to be armed, and then adapt to training a little, and they can basically be pulled to the front line to fight as qualified troops.


    For all knights, these members who have paid blood tax are also very valuable wealth. They have contacted exoskeletons and power armor on the front line, which can well train other knights. At the same time, they can also impart combat experience to them, so that recruits will not really be new.


    Fortunately, in addition to the Knights such as pine and sled knights who have not performed much military tasks, many Knights have fought a lot of public security wars. Their members have honed a good combat experience. With a little training, they can perform very well, and even directly dress up and go to the battlefield.


    However, it will take a long time for these knights to really come into use. After all, the equipment of the knights is the previous military equipment of various countries. Although there is no shortage of guns and ammunition, there is no equipment such as exoskeleton and power armor, not to mention the electromagnetic rifles widely used in the front line.


    These things need to be produced in sufficient quantities by the factory before they can arm these knights. Otherwise, they can''t effectively kill alien creatures with those ordinary equipment.


    This is also one of the main reasons why countries are not in a hurry to launch a counter offensive. After all, this is not World War I. two people can fire a gun. If there is no gun, they can pick up the dead man''s gun on the spot and press the bullet to fill the trench.


    As for weapons and equipment, there are not only exoskeletons, power armor and electromagnetic rifles. It takes a long time to prepare ammunition for electromagnetic rifles, batteries supporting exoskeletons and power armor, and various other transport vehicles and supplies.


    In particular, it is a big problem to use such a large-scale military force. People eat food chewed by horses.


    In order to solve this problem, European countries even asked China to build two new synthetic protein factories in the North Sea and the Baltic Sea in order to obtain more synthetic protein food for military grain reserves.


    This is certainly a bit stingy, but for European countries, it is the most economical and available way to hoard food.


    In addition to these, countries are also vigorously restoring their industrial production facilities and producing all kinds of weapons and equipment as much as possible.


    The damage was too complete to recover, so we had to find the European aid fleet to buy industrial production equipment produced by 3D printing equipment.


    I have to say that this is really a turn of Feng Shui. When Yanguo bought European machines, now Europe comes to buy Yanguo machines.


    In fact, they actually admire the 3D printing equipment of the European aid fleet. For industrial production, nothing is more fragrant than 3D printing equipment.


    However, for 3D printing equipment, Yanguo looks very dead. No matter what conditions countries offer, it is not for sale.


    Although it is said that there is a trend for all mankind to unite, and with the promotion of the South Tianmen plan, the process of European countries'' integration is even more advanced than they did in the half century after World War II.


    But even in this case, Yanguo still took some of its valuable technologies seriously and did not share them.


    After all, Yanguo suffered losses in this regard in those years. It is necessary to learn some lessons.


    Moreover, now that countries are still countries, they have not really unified into a human United regime, and some restrictions between countries should still exist.


    What''s more, even if mankind really has the trend and tendency to establish a joint regime to integrate all mankind into one regime, it is impossible for countries to really expose their best things to others if this joint regime is not established.


    Moreover, even if the United regime is established, countries will still form a force and group, and it is impossible to eliminate the differences between the original countries in a short time.


    This can be seen from the fact that Europeans have been engaged in European integration for so many years, and the last thing they do most is to translate documents.


    Even if someone is selfless, you can''t deny that most people are selfish.


    However, both Yanguo and Lucia support the European counterattack plan. While providing large amounts of aid to Europe, they are also more actively promoting the construction of the Middle East defense line, and plan to take the Middle East as a direction of counterattack.


    To this end, they are not only accelerating the construction of the Middle East defense line, but also consciously converging their troops towards the Middle East defense line.

    Although the original plan was to launch a counterattack after the completion of the Nantianmen plan, because the development and construction cycle of the large-scale Aerospace strategic carrier platform was somewhat too long, when European countries, even Lucia and Yanguo were ready for counterattack, the construction progress of the Luan bird large-scale Aerospace strategic carrier platform was still not even half.


    After three years of testing and R & D, the theoretical research and development, as well as various tests and designs of the large Aerospace strategic carrier platform have been completed.


    In the whole process of R & D and design, 3D printing technology has played an important role.


    This technology makes the manufacturing of test prototypes much easier and greatly shortens the construction period, which can shorten the whole R & D and design process to three years, and start the construction of this super aircraft immediately after the design and development is completed.


    It is more difficult than anyone can imagine to build a behemoth equivalent to at least four aircraft carriers.


    Not to mention anything else, just the plant itself that can accommodate this behemoth can be regarded as a super project.


    Without considering the demolition of the plant, it is also necessary to consider the problem of leaving the plant after the construction of the Luan bird large space strategic aircraft platform is completed.


    Therefore, in addition to having enough space to accommodate a behemoth more than 600 meters wide and more than 200 meters long, the plant should also have a super gate at least 700 meters wide and comparable to a long-span suspension bridge.


    It is difficult for designers and construction units to build such a plant in a conventional way.


    However, there are always more ways than difficulties. After some attempts and research, the plant was erected and successfully completed.


    If it is unrealistic to build a 700 meter wide gate, try a more realistic design.


    Therefore, the design team designed the whole plant with the top fully open. After the completion of construction, the Luan bird large-scale Aerospace strategic carrier platform did not translate out of the plant from the ground, but directly took off and left the plant from the openable ceiling on the top of the plant.


    This has undoubtedly greatly solved the construction problem of the plant, and such a huge plant can also be used as the hangar and maintenance site of Luan bird after it is retained.


    After all, it''s not easy to build such a large plant. It''s too wasteful to dismantle it. Luan bird itself also needs hangar and maintenance site. It''s a good choice to keep it.


    Relying on 3D printing technology, the construction of the plant is also very fast, and the construction of Luan bird starts at the same time as the construction of the plant.


    By the time the plant is fully completed, some basic parts of Luan bird have also been manufactured.


    As for parts, it is also compared with the huge size of Luan bird. Some completed parts will not be smaller than a large civil airliner.


    As for the most important wing skeleton, the 300 meter long skeleton, even if printed with 3D printing equipment, takes a lot of time to complete, and requires a special site. Therefore, the construction progress of Luan bird is not fast.


    According to the expectation of construction progress, it will take about one year to basically complete the construction of the whole Luan bird, and then it will take about one year to outfitting. Finally, the training and running in of crew members will take about one or two years.


    It will take at least three to five years for the whole Luan bird large-scale Aerospace strategic carrier platform to be put into actual combat.


    But Europe can''t wait.


    During the three years when Luan bird was built and European countries were preparing to fight back, European countries tried to fight back several times on a small scale.


    Three years is enough for European countries to complete the dressing of all their armies, and they have also purchased some small land ships and mobile bases from Yanguo, which has greatly improved the combat effectiveness of the army.


    Relying on these troops with improved combat effectiveness, they tried to counterattack in some areas where the previous defense lines were broken and concave, trying to flatten the defense lines and push them back to their original positions.


    Such counterattacks have achieved certain results. Although not every counterattack can achieve the expected operational objectives, with such attacks bit by bit, Europe has recovered some lost ground and gradually leveled the original uneven defense line like a dog''s bite into a straight line.


    They succeeded in bringing back most of the previously occupied areas of the whole defense line, and even played some prominent parts.


    This gave Europeans a lot of confidence. They even began to formulate a counter offensive plan. The whole plan was written in great detail, which made people mistakenly think that they were preparing for a world war.


    The Yanguo side also tried to carry out some attacks, starting from the completed defense line in the Middle East, and attacked the Cyprus Island close to Aleppo.


    Because of the weak offensive of alien creatures in this direction, the joint force composed of Yanguo and the Middle East army successfully occupied the island of Cyprus and established a solid base on it.


    Although alien creatures are powerful, their threat to humans has actually decreased a lot after humans can kill effectively and have shields to resist attacks.


    The success of the Yanguo attack can well explain the problem.


    After the improvement of human military science and technology, alien creatures can only rely on quantity to resist human attack.


    This has also greatly encouraged countries to launch a counterattack and completely eliminate alien organisms from the blue star. At the same time, some European countries do not want to wait any longer.


    After all, we have waited for three years. If we wait another three years, the morale of the people will be consumed.


    Both Yanguo and Lucia are aware of this situation. After assessing the power currently available to mankind, although the two countries still do not agree to start a large-scale counterattack immediately, they do not oppose a small-scale counterattack in local areas first.


    For example, recover the love sea area and the Apennine peninsula.


    Before, the two regions, one because of the rise of sea level and the other because of their geographical location surrounded by the sea on three sides, were quickly occupied when alien creatures invaded.


    European countries had a hard time defending alone, so there was naturally no way to face the fall of these two regions.


    But now with the power to fight back, European countries certainly want to recover their lost land.


    In particular, the Apennine peninsula is located in the middle of the whole Mediterranean. If we can recover the lost land, we can completely divide the whole Mediterranean into two parts, divide the forces of alien creatures into two, and then annihilate them region by region.


    This strategy was soon adopted, and European countries began to gather forces. This time, Lucia also sent her troops to the peninsula of Asia Minor, ready to join the army of Yanguo here, and then launch an attack on the love sea area.

 Chapter 869

    Several years later, when the children were studying this history in school, the history books called this counterattack the first counterattack war.


    The counterattack war lasted nine months. Europe mobilized nearly 7 million troops to participate in the war, accounting for more than 10% of the total population of Europe after the disaster.


    After nine months of arduous fighting and the convenience brought by the mountainous terrain of the Apennine Peninsula, this huge army finally pushed the front back to Sicily and successfully completed the strategic goal of dividing the Mediterranean into two.


    Lucia mobilized three million troops to the limit, and the two million troops sent by the United Nations crushed the alien creatures in the Aegean Sea with the momentum of an unstoppable torrent of steel, and recovered the Peloponnesian Peninsula, Crete and Rhode Island, as well as many islands in the Aegean Sea.


    Although many islands in the Aegean Sea were frozen under the ice due to the rise of sea level, several large islands remained, allowing the lucians to establish new strongholds and lines of defense here, suppress alien creatures, and then eliminate the remaining alien creatures in the whole Aegean Sea.


    In this war, mankind mobilized 12 million troops to fight with hundreds of millions of alien creatures.


    In the war, many brave people died and shed their blood on the earth.


    However, it is precisely because of their sacrifice and dedication that mankind can eliminate alien creatures, drive them away from our territory and recover the territory of mankind.


    And these sacrificed people are also recorded in history and remembered with the inheritance of human civilization.


    In nine months, hundreds of thousands of people were killed and injured. Mankind has achieved its strategic goal. It has also cleared the Aegean Sea and the Adriatic Sea, eliminating countless alien creatures. Their bodies and blood flow even covered the whole sea surface, and a thick layer was frozen by the cold.


    When the blue star thaws one day, I''m afraid these bodies will raise the sea level by another meter.


    However, no country has the idea of cleaning up these bodies. It is not that they do not want to, but that they simply do not have the ability to deal with such a large number of bodies.


    Just like the Dongting Lake in Yanguo, there are fierce battles on the lake, and the ice is frozen all over the bodies. If you can''t dig them out, even if you dig them out, unless you pull the recycled biomass to make synthetic protein blocks, even if you burn them, humans don''t have so much fuel to cremate them.


    In the face of this situation, countries really have no good way but to let these bodies be placed like this.


    After the first counterattack, because of the brilliant victory, both the morale and the people''s will of the human side have been greatly improved.


    By fighting side by side in the real sense, the estrangement between countries has been quickly replaced by comrades in arms fighting side by side.


    The experience of sharing life and death and striving for the future of mankind has even directly promoted the elimination of barriers among European countries and greatly accelerated the process of European integration.


    After all, the army is not like a national administrative department. It can provide a special translation team for each language for a little writing problem.


    In order to ensure the transmission of military orders, European countries have imposed a language as the language of military orders.


    The emergence of a common language is undoubtedly an important factor to promote the integration of countries.


    This counterattack war had a great impact on European countries, as well as on Yanguo and Lucia.


    After so many years, Lucia once again used large-scale foreign troops. If it was put before the disaster, it would undoubtedly scare people to death in European countries.


    However, in the current environment, it makes European countries rejoice, and even wants Lucia to mobilize 20 million troops to sweep everything like in World War II.


    For Lucia itself, this is also an opportunity for the country to get rid of its disadvantages and develop again.


    Lucia''s leaders did not give up this opportunity. Relying on the impact of the war, Lucia made a series of adjustments at home and completely solved some problems that have remained since the problem-solving era of suvia.


    Although Lucia, who has solved these problems, has been affected a lot for a while, putting aside the burden of countries, lucians soon found that their country seems to have returned to the era of grandparents'' mouth full of hope and ideals and children''s ice cream.


    Although there was no ice cream this time, everyone saw hope again.


    For a country, when its people are full of hope, then everything will not be difficult.


    In the war, although Yanguo did not send many troops, two million Yanguo troops played a role that seven million Europeans did not play.


    Relying on mobile bases, land ships and Titans, the two million troops of Yanguo are completely mechanized legions, acting as an irreplaceable blade in the attack on the Aegean Sea.


    The powerful armored forces not only participated in the Aegean war, but also participated in the final settlement of the Adriatic Sea in the final stage of the war.


    The infantry troops of Yanguo, fully equipped with exoskeleton and power armor, with electromagnetic shield, almost invincible tank torrent and Titan and heavy machine armor that always fall from the sky with victory, have really impressed the armies of European countries and Lucia.


    In nine months, those giant robots equipped with electromagnetic shields that can fall from the sky at any time with your call have become the most desired scene for every soldier participating in this war, because it means that the enemy in front of you will be completely crushed.


    Although all countries purchased land ships and Titans from Yanguo before the war, it is obvious that the airborne version is the latest model used by Yanguo. The latest expansion packages, including airborne devices and shield devices, are not for sale at all.


    This makes that even if European countries want to play Titan airborne like Yanguo, they don''t have enough technology to achieve it.


    Only the lucians turned over the technology of throwing tanks together with airborne soldiers in the suvian era, and managed to use Titans as airborne soldiers.


    Although the joint research of the South Tianmen project has successfully integrated the science and technology of various countries and reconnected the industrial systems of various countries into a whole, three years is not enough for them to turn their gains into real combat effectiveness.


    Therefore, after the first counterattack war, European countries took the initiative to stop the attack.


    They want to digest their gains, and humans need to accumulate more power to completely crush the alien creatures that occupy their homes.

 Chapter 870

    In the factory building, which is so huge that you can''t see the end at a glance, the construction of Luan bird''s large-scale Aerospace strategic carrier platform is coming to an end.


    At this time, as the general person in charge of the project, Chen Xin is standing on the super large vehicle above the Luan bird and inspecting the final construction work of the Luan bird.


    The huge fuselage with a length of more than 600 meters needs a plant with a length of 700 meters to accommodate, which makes it take more than ten minutes for the whole driving from one end of the plant to the other.


    But looking at the huge lead gray body of Luan bird from the sky, it really gives people an unspeakable shock.


    Especially when such a huge body is out of its own hands and has its own part in building it, there is a sense of achievement.


    "Academician, the main construction of luanyiao No. 1 has been completed by 97%, and now only the final installation and commissioning of internal equipment are left. According to the project progress, the final construction work will be completed within one month." beside Chen Xin, the Engineer in charge of on-site construction reported to Chen Xin with pride.


    Such a huge aircraft is unique in human history. Just being able to build it is an engineering miracle.


    As an engineer in charge of on-site construction, he really has enough reasons to be proud and proud.


    And not only the engineer, Chen Xin himself is also proud and excited.


    He still remembers that the first counterattack started immediately after Luan bird started construction. Luan bird''s construction was affected, but these workers overcame all kinds of difficulties, always stuck to their posts, and completed their work with quality and quantity and efficiency.


    In this process, every problem they overcome can be called the most in the world.


    Just give an example to understand how great they are. For example, the overall printing and hoisting of the 300 meter long wing keel is the largest thing in human history.


    You know, it''s equivalent to the size of an Eiffel Tower. Even if the wing keel adopts a lightweight structure and is not so heavy, it''s a great project.


    After that, the installation of four UAV launch tubes is equivalent to installing four amphibious attack ships on the wings.


    Not to mention the installation of the skin on the body surface, the skin of the multi-layer composite structure is installed manually by workers, and the final product is a 600 meter long wing, with an error of no more than 1 mm at the left and right ends.


    These workers have created an incomparably brilliant miracle with incomparably exquisite skills and unimaginable sense of responsibility and care.


    Now, this huge unimaginable behemoth is finally going to complete the final construction and wake up to fly in the sky. How can it not make the people involved in its construction feel proud, proud and excited?


    "The more this time, the more we can''t relax our vigilance. It''s the last moment. Let''s work harder, but we can''t make mistakes at this time!" Chen Xin has a beard on his face at this time. In order to build Luan birds, he is too busy to shave his beard: "we''ve finished the 99 worship. Don''t ruin it on this last shiver."


    "Academician, please rest assured that all our construction personnel are ready. In the last month, even if they are nailed to the construction site without eating or sleeping, they will complete the construction of luanbiao No. 1 with quality and quantity on time, and there will be no mistake!" the engineer said quite sonorous and powerful, showing great determination.


    "That''s what you want! Come on, I''ll give it to you! When the Luan bird construction is completed, I''ll ask you for help!" Chen Xin patted the engineer on the shoulder and encouraged him.


    After getting off the train, Chen Xin got into the Luan bird for inspection.


    The internal structure of this huge Aerospace strategic aircraft platform is not inferior to that of an aircraft carrier.


    Or put another way, it is an aircraft carrier flying in the sky.


    Of course, such a huge Luan bird cannot be driven by a little crew. Up to hundreds of crew members will be responsible for maintaining the normal operation of Luan bird, and the living cabin under construction is the guarantee for maintaining the normal life of hundreds of people in Luan bird.


    Although in order to ensure that the total weight of the body is not too heavy, this part of the living space adopts the extreme lightweight design, it still has enough guarantee for the quality of life of the crew members who need to stay in the sky for a long time.


    The cabin has enough space for the crew to live and rest. There are all kinds of supporting facilities such as bathroom and toilet, and even shops, canteens and gyms.


    It can be said that like the aircraft carrier, it is simply a complete living community with perfect living facilities.


    In addition to these, the whole Luan bird large space strategic aircraft platform is a complete war machine.


    In order to ensure the operation of this giant, Luan bird has installed four small fusion reactors, so that the whole body has abundant and surging energy, which is enough to support the shield system covering the whole Luan bird and ensure the normal operation of the body.


    Moreover, the four small fusion reactors are not connected in series. Even if one of them fails, the other three can ensure the normal operation of Luan bird.


    In fact, as long as one of the four reactors can operate normally, it can ensure that Luan birds can take off and land normally and start the weapons on the body to fight.


    In addition, in order to ensure that the Luan bird''s huge fuselage can fly smoothly, three anti gravity generators are installed on this huge aircraft for the first time to ensure the stability of the Luan bird''s fuselage.


    As for the combat effectiveness of Luan bird, it mainly depends on the air and space unmanned fighters launched by the four UAV launch tubes, as well as air defense weapons all over the body.


    After three years, Xuannv Aerospace unmanned fighter has finally been successfully developed. This kind of unmanned fighter that can independently break through the atmosphere and reach outer space for combat is extremely powerful. In addition, unmanned fighter can make more movements that do not need to consider the driver''s affordability. This kind of fighter has completely exceeded all human fighters at present, It is listed as a completely new generation of fighter.


    Previously, in the first counterattack war, the land aircraft carrier was used to carry the first batch of Xuannv fighters officially designed and completed for Aegean sea operations. When facing the overwhelming number of alien biological flying units, they made extremely amazing achievements.


    With its own zero loss, only one Xuannv fighter damaged its wing and was forced to make a forced landing. It completely wiped out all alien biological air flight units in the Aegean Sea. At that time, the Xuannv fighter participating in the battle was only a quarter of the carrying capacity of Luan birds.


    It is precisely because of the terrible air battle between the two belligerents that all countries have made up their minds to fully train and install the air and space fighters, retire the original fighters, and concentrate the most elite Ace Pilots on the Luan bird.


    Chen Xin naturally saw the Xuannv fighters installed into the launch tube on the Luan bird. These fighters will be remotely controlled by the pilots sitting on the Luan bird.


    Although the painting style may look like playing a game, it has to be said that this operation mode can avoid the loss of elite pilots to the greatest extent.


    After all, pilots who can control air and space fighters are very valuable. Almost every one is a trump card and an absolute elite.


    Standing in front of the UAV launch tube and looking at those Xuannv fighters fixed on the launch rack, Chen Xin couldn''t help but sigh: "I really hope to see them flying in space as soon as possible!"


    "It''s fast, academician. As long as the final equipment installation and commissioning are completed, Luan bird can carry out test flight, and these fighters will certainly fly at that time." the staff on one side heard Chen Xin''s emotion and couldn''t help laughing at him.


    In the view of the staff, Chen Xin, as the general person in charge of the South Tianmen plan, should participate in this test.


    However, Chen Xin just smiled and shook his head without saying anything.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    Time always flies. The final stage of the construction of Luan bird large-scale Aerospace strategic carrier platform was completed very quickly. Only three months after Chen Xin''s last inspection, all the construction and commissioning were completed and officially put into use.


    As for the outfitting and crew running in, these are the follow-up.


    Chen Xin, as the general director of the South Tianmen project, has been proud to say that he has completed the largest project in the history of mankind after delivering the Luan bird large-scale Aerospace strategic aircraft platform to the military.


    Watching the 700 meter long ceiling cover plate on the top of the plant unfold in turn, the huge Luan bird large space strategic aircraft platform rises slowly under the action of the anti gravity generator and occupies all his sight. The spectacular spectacle of blocking the sky and the sun is really indescribable to describe his pride and moving.


    The feeling of excitement and oppression brought by the passing of giants from the top of the head is even more soul stirring to the unparalleled extreme.


    Watching the Luan bird rising slowly, Chen Xin finally took a breath as if he had taken off the burden and said, "my work can finally be over."


    "Academician, have you really decided?" a staff member nearby heard Chen Xin say so, as if he wanted to persuade him again.


    However, Chen Xin shook his head and said, "the South Tianmen plan has exhausted my efforts and energy. It is also the most proud achievement in my life. Now I have died without regret."


    "But the country still needs you!" the staff was excited when they saw Chen Xin brushing his clothes.


    The country still needs itself. This really made Chen Xin shake and hesitate, but finally he shook his head, took off his white coat symbolizing the identity of a researcher, took off the badge of academician''s identity hanging on his chest and handed it to the staff member.


    "Allow me to be selfish. I''m just a lucky guy. There are more people who are more useful to the country than me, but there''s a lot less of me, isn''t there?" Chen Xin smiled and felt relieved to unload the burden: "and I''m not saying I don''t contribute to the country anymore, but I just want to change the environment."


    "Where are you going, academician?" the staff still wanted to persuade Chen Xin, but it was obvious that Chen Xin had decided to go.


    Chen Xin smiled and raised his finger to the sky: "I have a date with the moon. I''m going to this date now."


    With that, he turned and left regardless of the staff''s gaping expression.


    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª


    A year later, a small lunar base has been built.


    This is the first permanent base established by mankind on the moon. All countries... No, it should be called the human alliance now. After the end of the South Tianmen plan, all countries put forward this proposal to promote the real integration of mankind into a whole.


    Although there are still theoretical problems in various countries, European countries have announced the cancellation of the original boundaries between countries and began to officially promote European integration in preparation for the complete elimination of alien organisms.


    Now within the human alliance, only Lucia and Yanguo still maintain the original national boundaries, but the two countries are also discussing how to eliminate the gap and truly realize the human alliance.


    One of the manifestations of this proposal is that the lunar advance team composed of astronauts and scientists from various countries no longer belongs to various countries, but uses the name of the human alliance.


    With the help of Yanguo''s spacecraft, they have established a permanent base on the moon and will become the first permanent residents of the moon.


    This can be said to be a milestone step in human history.


    At the moment, everyone in the moon base gathered in the restaurant and was singing a birthday song.


    "Happy Birthday to you, Chen Xin!" an astronaut from Lucia sent Chen Xin a cake. The gravity of the moon is very small, so his action appears very careful.


    However, Lucia''s astronaut is quite strong, and his cautious actions are somewhat funny.


    However, no one here will laugh at anything. Everyone watched him deliver the cake to Chen Xin with blessings.


    "Thank you, this is my first birthday on the moon! It''s also the most meaningful birthday!" Chen Xin looked at the others, glanced at Qin LAN and Mo Qingyan standing next to him, and said to them, "ah LAN and Qing Yan, can you blow candles with me?"


    "Good!" Mo Qingyan smiled and happily agreed.


    The three blew out the candles together. After everyone applauded, Chen Xin took out a knife and cut the cake.


    But the cake is not big enough to give everyone a piece. He can only cut it as small as possible so that more people can taste it.


    After sharing the cake, this little celebration will soon end. After all, everyone has a lot of things to do and doesn''t have much free time.


    After eating his birthday cake, Chen Xin put on his driving suit and walked towards the hangar.


    The magnetic boots on his feet ensure that he will not fly because of the low gravity of the moon, but the feeling of walking under low gravity is not very good.


    Qin LAN and Mo Qingyan also follow up. The three of them will drive their Titans to a meteorite crater for investigation.


    Although there are two lunar rovers in the lunar base, but the other two scientific research teams want to use them, Chen Xin and they have to use Titan.


    And compared with the lunar rover, Chen Xin prefers to drive the white dragon.


    On the way to the hangar, Qin LAN suddenly asked Chen Xin, "ah Xin, are you really well? The acquired scholar syndrome can be cured. Forget your acquired ability. This is also a wonder in the world."


    "Anything can happen, can''t it? Besides, without that special ability, I''m not a waste. Isn''t it good now?" Chen Xin smiled, put on his helmet and jumped into the white dragon''s cockpit.


    The low gravity of the moon makes it easy for him to do this.


    Qin LAN looked at Chen Xin sitting in the cockpit, frowned and shook his head: "this guy must not be telling the truth!"


    "Why do you care so much? He has no special ability. Isn''t it good to spend more time with us?" Mo Qingyan pushed Qin LAN behind her and smiled at her: "let''s go. There''s still a lot of work to do today!"


    With that, she also jumped on her Titan, closed the hatch cover and started it.


    Qin LAN didn''t say much. He also jumped on his own Zhu Luan and started it.


    "Today''s task is to survey the meteorite crater in the south, obtain rock samples, analyze the mineral composition of the meteorite crater, and prepare for the establishment of the mine later. There are many things. Let''s go!" Chen Xin said in the communication channel, driving Bai Long to the air lock.


    "Let''s play, see who arrives first! The lost man sleep on the floor tonight!" Mo Qingyan suddenly came up with an idea, and said to the other two.


    "Competition? Hehe, white dragon will not lose!" Chen Xin''s voice was full of confidence.


    "Isn''t this a joke? We''re going to perform the task. Are you too relaxed?" although he said so, Qin Lan also secretly clenched the joystick and was ready to start.


    With the opening of the airlock, the three Titans started instantly and rushed out together.
